Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to human waste treatment for treating human waste outdoors, without purification facilities, in transportation systems such as ships and trains, and in tunnels that are closed from the surroundings and do not allow vacuum cars to enter. The present invention relates to a device, and more particularly to a defoaming mechanism of a human waste processing device that can prevent the processing from being effectively performed due to bubbles generated when human waste is heated.

[0002]

2. Description of the Related Art In a general house, human waste excreted from the human body is generally discharged to a sewer pipe by a flush toilet or the like, or temporarily stored in a septic tank for purification and then discharged to a river. However, when performing outdoors, for example, in a venue where a large number of personnel such as an athletic meet, a trade fair, and a rally are held, a temporary toilet is conventionally provided to eliminate the physiological phenomenon of the participants.

[0003] As described above, in the conventional treatment of human waste outdoors or in a place without a purification facility, a movable temporary toilet is used. However, most of them have a structure having a toilet tank for temporarily storing human waste, and human waste excreted from the human body is directly stored in this toilet tank. Therefore, after using the temporary toilet, the human waste stored in the toilet tank must be collected by a vacuum car or the like and transferred to a human waste processing facility. For this reason, the post-collection processing is required, and the post-processing is troublesome and unsanitary.

[0004] Transportation systems such as trains, buses, ships, and the like that travel long distances are provided with a dedicated tank for storing excreted human waste. After the processing, a method of collecting by a vacuum car at a terminal station or a relay point was generally used.

[0005] As described above, in the conventional disposal of toilets or movable transportation, human waste is mostly stored while being excreted from the human body and then collected. For this reason, any of the storage method, the recovery method, and the treatment method has to be said to be non-modern and extremely unsanitary. Therefore, when the temporary toilet has been used for a long period of time, excreted human waste remains in the tank, causing odor. In addition, since the operation of cleaning the temporary toilet after use is disliked by workers, it is not preferable from the viewpoint of modernization of maintenance of the temporary toilet and the toilet of transportation.

Under such circumstances, various methods for sanitary disposal of human waste have conventionally been considered. For example, there is a method of disinfecting and deodorizing by inputting a chemical agent together with human waste. This method is often used for transportation such as Shinkansen, but since urine containing chemicals circulates between the tank and the toilet, the water flowing through the toilet becomes dirty after a long-term use.
It had a bad smell and was unpopular for users. Further, in order to empty the tank and prepare it for the next use, a large amount of chemical must be introduced into the tank, which has the disadvantage of increasing the cost of the chemical.

[0007] Further, a method has been considered in which human waste is stored in a bag of vinyl or the like and packed to prevent the emission of odor. However, a large amount of plastic bag must be used for each excretion, which increases the processing cost and requires a process for separating human waste from the plastic bag at a later date. With this method, the process until packing is relatively easy,
Subsequent processing is cumbersome, and the processing facility becomes large.

Further, a method has been considered in which excreted human waste is stored in a closed evaporation container, and the human waste is directly heated and evaporated by the heat of a burner. For example, patent publication Showa 4
No. 17236, Patent publication No. 2545, Showa 1974, Patent publication No. 3149, Showa 50, Patent publication 58
No. 239, Japanese Patent Publication No. 110268/1982, and Japanese Patent Publication No. 55415/165415 are known. However, in these methods, since the flame of the burner is squirted into human waste to evaporate from the surface,
Moisture, a major component of human waste, cannot be evaporated efficiently,
It required a lot of energy to completely process human waste.

[0009] Further, with these configurations, the evaporating container is not cleaned after the human waste is dried, and the residue that cannot be evaporated from the human waste accumulates on the bottom of the evaporating container in a long-term use. The thermal efficiency became worse. In such a case, in order to clean the residue, the apparatus must be disassembled and maintenance must be performed each time, and there is a disadvantage that the maintenance is troublesome and expensive.

As described above, there are many problems in the treatment of human waste in a temporary toilet, and it is difficult to completely excrete human waste in the temporary toilet. Due to such social demands, the same inventor as the applicant of the present application has proposed a human waste processing apparatus that can heat the human waste to evaporate water, which is a major component of the human waste. The proposed human waste processing apparatus is provided for use in a temporary toilet, and a sealed drying pot (heat-resistant evaporating vessel) for storing human waste is provided in the apparatus. A rotatable stirring blade is rotatably supported, and the drying pot has a configuration in which a plurality of heat accumulators that roll on the inner bottom together with human waste according to the rotation of the stirring blade are housed.

The drying pot is heated from the outside to heat the waste in the drying pot, and at the same time, by rotating the stirring blade, the waste can be mixed and the moisture of the waste can be quickly evaporated. At the time of this evaporation, the spherical heat storage element rolls at the bottom of the drying kettle to uniformly heat the temperature of the human waste, and to transfer the heat of itself to the human waste to increase the heating rate. (For example, Japanese Patent Application No.
No. 4150).

This mechanism is basic, and the inventor has successively proposed an improved human waste treatment apparatus. Japanese Patent Application No. 164594/1990 discloses a configuration in which a pipe for supplying air to a drying pot and an exhaust pipe are connected, and the exhaust pipe is connected to a dust collector and a condenser. In this mechanism, the water vapor of the human waste evaporated inside the drying pot is condensed and collected, and can be circulated and used for washing water.
Dust remaining in the drying pot after drying of human waste is sucked and collected together with air, and the dust can be separated from air by a dust collector. By this mechanism, moisture can be collected from the human waste put into the drying pot, and the non-evaporable dust remaining in the drying pot after the drying of the human waste can be cleaned, so that the human waste processing apparatus can be used continuously. It is.

In Japanese Patent Application No. 411577/1990, a human waste treatment apparatus is unitized so as to be easily installed in a temporary toilet. In this mechanism, the structure of the drying pot is formed in a cylindrical shape so that human waste can be introduced from the side of the drying pot. For this reason, there is no need to dispose the toilet on the upper part of the drying pot, and the height of the apparatus can be reduced.

In Japanese Patent Application No. 412559/1990, a storage tank for storing urine collected by a urinal is provided, and the storage tank and the urinal are connected by an ejection pipe. In this configuration, urine and urine are excreted in the urinal, and urine is separated so as to be collected in the urinal. It can be put into a drying pot. For this reason, the toilet can be cleaned with urine, and the temporary toilet can be flushed even in a place where water supply cannot be installed.

[0015] Furthermore, in Japanese Patent Application No. 03-67538,
A mechanism is shown in which a liquid level sensor is inserted from the side of the drying pot, and the position of the liquid level of the human waste put into the drying pot can always be detected. In this mechanism, by detecting and judging the liquid level of the human waste, it is possible to prevent a large amount of human waste from being temporarily supplied, thereby preventing the ability of the human waste to evaporate, and to prevent a failure due to overflow. This can prevent the occurrence.

In Japanese Patent Application No. 189280/1991,
A reheating box with a built-in heater is arranged between the blower and the catalyst box, and a bypass is provided between the catalyst box and a pipe connecting the drying pot and the dust collector. With this configuration, the air from the drying pot can be made to flow to the catalyst box by the bypass during the evaporating process of the excrement, and the air flow can be made more efficient. Further, during the cleaning process of the drying pot, the bypass is closed, and the air containing dust can flow to the dust collector as it is.

Japanese Patent Application No. 189281/1991 is an improvement of the Japanese Patent Application No. 189280/1991. A bypass pipe is connected to a pipe connecting the drying pot and the dust collector, and the end of the bypass pipe is connected to the end of the bypass pipe. Is a configuration in which the negative pressure side of the ejector is connected and the catalyst box is connected to the ejector. In this configuration, when the bypass pipe is open, the air in the drying pot is forcibly sucked by the ejector and made to flow into the catalyst box, so that the air flow efficiency of the drying pot is increased and the evaporation is promoted. effective.

In Japanese Patent Application No. 265237/1991, a trash collection box is connected to an exhaust pipe of a drying oven, and a trash bag formed of paper, cloth, or the like is stored in the trash collection box. In this configuration, when cleaning the drying pot, air containing dust flows into the garbage bag, and only dust passes through the garbage bag and the dust can be separated. There is an effect that dust can be separated more reliably than a cyclone type dust collector.

[0019] In Japanese Patent Application No. 051170/1993,
The toilet and the human waste treatment apparatus are separated, and the human waste put into the toilet is stored in a tank, and then the evaporating and drying process can be continuously performed in a badge type. In this human waste processing apparatus, an opening for introducing human waste is formed at the top of a slightly spherical drying pot that can be rotated on a horizontal axis, and a spherical heat storage element is stored inside the drying pot. This is a configuration in which a burner capable of heating is provided. With this configuration, the human waste put into the drying pot is evaporated and dried by the heat of the burner. During this process, the human waste can be stirred by the heat storage body by swinging the drying pot, and after the drying, the drying pot is rotated. This allows dust to fall from the opening.

In Japanese Patent Application No. 121968/1993, a switching valve is interposed between an air supply pipe and an exhaust pipe of a drying oven, and a dust collection box and a blower can be connected in series to the drying oven via the switching valve. is there. With this configuration, air is circulated inside the waste disposal apparatus when cleaning the drying pot, and there is an effect that dust collection efficiency is improved.

Japanese Patent Application No. 125360/1993 has a configuration in which a high-frequency coil is installed on the lower surface of a drying pot, and high-frequency power is supplied to the high-frequency coil to generate electromagnetic waves. Since high-frequency electromagnetic waves are mixed in the drying pot, the drying pot itself generates heat instead of direct heating, thereby heating the human waste. For this reason, it is possible to quickly heat only the necessary drying kettle, which has the effect of reducing heat loss.

In Japanese Patent Application No. 307135/1993, the drying pot itself is normally upright, the upper part of the drying pot is always open, and the drying pot can be turned over only during cleaning. A heat storage body is accommodated inside the drying pot, and a lid plate that can be closed at the time of a fall is provided at an upper opening. In this configuration,
During the process of evaporating and drying the excrement thrown into the drying oven, the drying oven itself stands still and stands upright. The dust remaining in the opening can be released from the opening. At the time of this dust emission, the lid plate (there are several small holes on its surface) automatically closes the opening of the drying pot,
It prevents the heat storage material from dropping, and allows only dust to be released to the trash dish through a small hole in the lid plate.
The configuration of the human waste treatment apparatus can be simplified.

Further, in Japanese Patent Application No. Hei 5-314445,
The drying pot is supported rotatably, the output of the motor is engaged with the outer periphery of the drying pot, and a plurality of spherical heat storage elements are stored in the drying pot. Three baffle plates are inserted from the lid plate to the inside of the drying pot. In this configuration, unlike the conventional drying pot of the human waste processing apparatus, the drying pot itself rotates around a vertical axis, and the human waste can be heated by the electromagnetic wave from the high frequency coil. The heat storage element accommodated in the drying pot does not rotate with the drying pot due to the baffle plate, but rolls at the bottom of the drying pot, and can stir and heat human waste. In this configuration, there is no need to rotate the stirring blade inside the drying pot,
The height of the entire human waste processing apparatus can be reduced. Further, in the configuration in which the rotating blades are rotated, an excellent effect of eliminating a failure caused by foreign matter (eg, a ballpoint pen, clothing, a clock, etc.) put into the drying pot being entangled with the rotating rotating blades. It has.

Also, in Japanese Patent Application No. 151631/1994, similarly, a drying pot is rotatably supported, the output of the motor is meshed with the outer periphery of the drying pot, and a spherical , And a single baffle plate is inserted from the lid plate located at the upper part of the drying pot toward the inside of the drying pot. Even with this configuration, the drying pot itself rotates around a vertical axis, and the human waste can be heated by the electromagnetic waves from the high-frequency coil. According to the present invention, the baffle plate is formed of one piece fixed to the suction pipe, and since the heat storage body does not fit between the plurality of baffle plates, the heat storage body can be reliably rolled by rotation of the drying oven. Met.

In these newly proposed human waste processing apparatuses, the excreted human waste can be heated while being sealed in the drying pot, and the human waste can be mixed by rotating the stirring blades and the drying pot. . The temperature of the heated human waste uniformly rises, and most of the moisture, which is a component, evaporates and is released into the atmosphere as water vapor. By this heating and mixing, the rate of evaporation of human waste is increased, and the processing time of human waste can be shortened. In addition, water vapor diffused into the atmosphere is deodorized with a catalyst or the like. This is also preferable from the viewpoint of the above.

It is extremely sanitary to evaporate and diffuse human waste in the sealed evaporating container in this manner, and the operation can be systematized, so that no burden is imposed on the operator in maintenance and the like. is there. However, most of the conventional human waste processing apparatuses have a configuration in which a drying pot is fixed, and the stirring blades are rotated inside the drying pot to mix the human waste. In this mechanism, when foreign matter other than human waste, which cannot be evaporated, is introduced into the drying pot, the rotating stirring blade meshes with the foreign matter, which often causes a failure. For example, a metal ballpoint pen, belt, clothing, or the like may be thrown into the toilet bowl by the user's carelessness. When these foreign substances are thrown into the drying pot, the foreign substances bite between the stirring blade and the drying pot, causing rotation of the stirring blades to stop, and causing a phenomenon that the stirring blades and the drying pot are worn.

Further, if the stirring blades are stored inside the drying pot, the limited internal space of the drying pot is narrowed by these mechanisms, so that the internal space of the drying pot cannot be used effectively. Had become.

To solve such a disadvantage, Japanese Patent Application No.
In Japanese Patent Application No. 314445 and Japanese Patent Application No. 151631, Japanese Patent Application Laid-Open No. HEI 15-1631 discloses a configuration in which the drying pot itself is rotated so that human waste can be mixed without using a stirring blade. But
In this mechanism, the drying kettle must be rotatably supported, and furthermore, the drying kettle must be supported so that it does not move in the vertical direction and the center axis does not deviate. If the rotating drying kettle moves up and down or if the rotating shaft moves in a miso grinding motion, the opening end of the drying kettle will be separated from the lid plate, and the airtightness of the drying kettle will not be maintained.

As described above, in order to restrict the rotational movement of the drying oven, a regulating mechanism (a roller or the like) in two directions, a vertical direction and a rotating direction, is required, and this regulating mechanism must be complicated. It is. In addition, if the regulation mechanism becomes complicated, it takes time and effort to assemble the drying pot, and it takes time to remove the drying pot for inspection and maintenance of the human waste processing apparatus. .

Dust remaining after the human waste is evaporated and dried in the drying oven must be removed in order to continuously treat the human waste, but a suction pipe for cleaning is attached to the drying oven by a predetermined amount. It was difficult to control the insertion by the length. Conventionally, the amount of movement of the suction pipe is detected and controlled so that the suction pipe can be moved up and down by an appropriate length. However, a mechanism for moving the suction pipe and a control mechanism are complicated.

For this reason, the inventor of the present application filed Japanese Patent Application No.
No. 9457 has filed an application for a human waste treatment apparatus in which these disadvantages are improved. In this newly proposed human waste processing apparatus, a rotation holding means is provided at the upper part of the gantry, an evaporation container is hung below the rotation holding means, and an electromagnetic heating means is provided at an interval on the lower surface of the evaporation container. It is characterized by the following. In this proposed configuration, since the evaporating container is suspended and rotated, there is no need to provide any support means on the lower part and the side surface, and the mechanism for holding the evaporating container is extremely simple.

Also, with this configuration, only the evaporation container can be removed from the lower part of the rotation holding means,
It becomes easy to expose the inside of the evaporation container to the outside for periodic inspection and maintenance. It is possible to remove the covering means covering the upper part of the evaporation vessel and observe the inside of the evaporation vessel from above. This is because such a procedure becomes much more complicated.

As described above, in order to put human waste into the evaporating container and to heat and evaporate the human waste together with the evaporating container for processing, a mechanism for stirring the human waste to uniformly increase the temperature of the human waste must be provided. It must not have been. For this stirring, either the stirring blade is rotated at the center of the inside of the evaporation container to stir the waste, or the stirring blade is fixed so as not to rotate and the evaporation container is rotated to stir the waste. That configuration was adopted. Among these, a mechanism for fixing the evaporation container and rotating the stirring blade (for example, Japanese Patent Application No.
No. 90857), the mechanism for pivotally supporting the stirring blade is simplified, and the evaporating vessel can be firmly supported. However, because of the mechanism for rotating the stirring blade near the bottom of the evaporation container, it has been difficult to collect dust remaining in the evaporation container after evaporating the human waste. This is because it is impossible to install a pipe for sucking dust near the bottom of the evaporating vessel by the stirring blade, and it is necessary to suck dust from near the lower end of the rotating shaft that supports the stirring blade.

In a mechanism for rotating the evaporation container and fixing the stirring blade (for example, Japanese Patent Application No. 151631), the evaporation container is provided on the lower surface of a horizontal top plate so as to be rotatable in an airtight manner. A mechanism for suspending a pipe provided with a baffle plate from the top plate to the lower side of the evaporation container has been employed. In this mechanism, when the evaporating container is rotated, the baffle plate relatively rotates near the bottom of the evaporating container, so that the human waste rotating with the evaporating container can be stirred. With this mechanism, the pipe that holds the baffle plate approaches the bottom of the evaporation container and is located off the center of the evaporation container, making it easy to suck dust evenly at the bottom of the evaporation container. This has the feature that the evaporating container can be reliably cleaned.

However, in this mechanism, it is necessary to hold the evaporating container in a rotatable manner, so that the holding mechanism is complicated, and it is difficult to suspend a heavy evaporating container. In addition, since the space between the top plate and the rotating evaporating container must be maintained in an airtight and rotatable manner, there is a disadvantage that the airtightness of the joint portion must be improved. Since the upper end opening of the evaporating vessel is relatively wide, a large-diameter sealing material must be used to maintain the opening rotatably while maintaining airtightness. Had occurred. For this reason, there has been proposed a structure in which a rotating pipe is rotatably supported on a cover plate, the pipe is bent in a crank shape, and a half-moon-shaped stirring blade is fixed to a lower portion of the pipe (for example, Japanese Patent Application No. Hei 7 (1994) -197686). No. 301980). With this configuration, it is easy to keep the container airtight, and the production and assembly are simplified.

[0036]

[Problems to be solved by the invention]

As described above, when human waste is put into the evaporating container and heated, the human waste in the evaporating container is heated and boiled, and the water which occupies most of the components of the human waste is evaporated as water vapor. In this evaporation of human waste, the evaporation container is sealed,
Sanitary treatment can be carried out without spreading offensive odor to the surroundings. However, human waste contains various components, and when the human waste boils, these components generate fine bubbles. At the same time, to stir by the stirring blades to raise the temperature of the human waste uniformly,
Countless bubbles are likely to be generated on the surface of human waste. The generated bubbles are accumulated on the liquid level of the excrement and eventually fill the internal space of the evaporation container. An exhaust pipe for discharging the water vapor to the outside is connected to the upper portion of the evaporating container. When the internal space of the evaporating container is filled with bubbles, the bubbles flow from the exhaust pipe to the next processing mechanism.

An exhaust pipe connected to the sealed evaporating vessel is connected in series with a reheating mechanism for heating the evaporated water vapor and a deodorizing mechanism containing a catalyst such as platinum. In this reheating mechanism, the steam flowing out of the evaporation container is heated again to raise the temperature to a predetermined temperature, and then,
Odorous components were redox-reduced by bringing steam into contact with the catalyst contained in the deodorizing mechanism. By the reheating treatment and the oxidation-reduction treatment, the malodorous element contained in the steam is altered to change it to be odorless and then diffused to the outside. Since such a processing mechanism is connected to the evaporating container, if bubbles generated by heating the human waste flow from the exhaust pipe to the reheating mechanism and the deodorizing mechanism, the inside of these mechanisms will be bubbled. Was to be charged. If the foam fills the reheating mechanism and the deodorizing mechanism in this way, it would not be possible to process the steam by directly flowing the steam as it is, and the intended processing could not be performed. Furthermore, when foam generated from human waste fills the inside of the reheating mechanism and the deodorizing mechanism, various components contained in the foam adhere to the inner walls and members of the reheating mechanism and the deodorizing mechanism, which may cause a failure. Was. Also, if bubbles adhere to the surface of the catalyst housed inside the deodorizing mechanism, it has also been a factor of reducing the redox function.

For this reason, it is preferable that bubbles are not generated when the human waste stored in the evaporation container is heated.
Further, even if bubbles are generated, it is preferable that only the water vapor be allowed to flow out without causing the bubbles to flow out of the evaporation container to the outside. In response to such demands, it has been desired to develop a mechanism for reducing bubbles generated from human waste even when the human waste stored in the evaporation container is heated. Then, it may be to prevent bubbles generated by heating the human waste from flowing from the evaporation container to another mechanism, and further, liquefy the generated foam and return it to the remaining human waste. The same objective can be achieved by doing so. Further, the same object can be achieved by interposing a mechanism for eliminating bubbles between the evaporating container and another mechanism so as to prevent the bubbles from flowing to the next other processing mechanism.

The lower end of the hanging pipe 107 and the upper end of the oblique pipe 108 are air-tightly connected by electric welding or the like. This allows air to flow to the center of both without leaking.

The lower end of the oblique pipe 108 is cut obliquely, and the lower end of the oblique pipe 108 is cut in the oblique pipe 1 direction.
08 has the same direction as the cutting direction. A suction pipe 109 is provided at the lower end of the inclined pipe 108.
The upper end of the suction pipe 109 is cut obliquely in the opposite direction to the lower end of the oblique pipe 108.
When the upper end of the suction pipe 9 is connected, the axis of the suction pipe 109 is held vertically (in other words, the hanging pipe 107 and the oblique pipe 108 are bent in the shape of a triangle as shown in FIG. 7. Therefore, it is configured to be cranked by the hanging pipe 107, the inclined pipe 108, and the suction pipe 109.) This suction pipe 109 has a through-opening at the center thereof and has a pipe shape with upper and lower ends opened.
09 is airtightly connected to the upper end of the housing 09 by electric welding or the like, so that air can flow to the center of the two without leaking.

Thus, the hanging pipe 107 and the oblique pipe 108 are connected obliquely, and then the oblique pipe 108
And the suction pipe 109 are connected obliquely in the opposite direction, and the hanging pipe 107, the oblique pipe 108, and the suction pipe 109 form a single pipe-shaped crank body 102. In this crank body 102, as shown in FIG.
, And both are held vertically. And the hanging pipe 107 and the oblique pipe 1
08, since the joint surface of the suction pipe 109 is welded in an airtight manner, the crank body 102 performs the same operation as a single pipe, and air is supplied from the upper end opening of the suspension pipe 107 to the lower end opening of the suction pipe 109. Can flow without leaking.

The triangular plate 110 is fixed to the upper part of the suction pipe 109 by electric welding or the like.
9 is fixed to the lower portion of the base plate 9 by electric welding or the like, and the triangular plates 110 and 111 are arranged in parallel at an interval above and below.

The straight sides of the triangular plates 110 and 111 are rectangular side plates 112 and 113, respectively.
(In FIG. 12, the other side plate 113 is hidden behind the side plate 112 and is not shown. See FIG. 9). The triangular plates 110 and 111 and the side plates 112 and 113 are integrated. The structure is assembled. In these triangular plates 110 and 111, each side facing the center of the drying pot 51 is concave in an arc shape, and the back side of the curved stirring plate 114 is in close contact with the arc-shaped side. The back of the stirring plate 114 and the triangular plates 110, 1
11 and the contact sides of the side plates 112 and 113 are hermetically fixed by electric welding or the like, thereby forming a slightly triangular box-shaped structure that is sealed from the outside.

Further, an upper end of a skirt plate 115 formed by bending a thin steel plate into a tapered shape is fixed to an arc-shaped lower side of the agitating plate 114. It has a shape similar to a dump plate. 6, the radius of curvature of the stirring plate 114 is set to be larger than the radius of curvature of the inner periphery of the drying pot 51, and the length of both ends of the stirring plate 114 is slightly smaller than the inner diameter of the drying pot 51. It is set to the extent that it becomes smaller. For this reason, in the stirring plate 114 fixed to the triangular plates 110 and 111, the straight line connecting both ends of the stirring plate 114 passes near the center of the drying pot 51 (see FIG. 6), and the stirring plate 1

FIG. 6 shows a plane in which the stirring section 28 is suspended from the bearing section 24. Both ends of the stirring plate 114 are located at positions slightly apart from each other so as not to contact the inner wall of the drying pot 51. In addition, the center of the arc-shaped stirring plate 114 is separated from the inner wall of the drying pot 51 by a distance of about １ ／ of the inner diameter of the drying pot 51. 7 and 9 show the side surface of the stirring unit 28 suspended from the bearing unit 24.

[Configuration of Drive Unit 22]

Next, the configuration of the driving section 22 will be described with reference to FIGS. The main member of the drive section 22 is constituted by a cylindrical motor 118, and a rectangular gearbox 119 for reducing the rotation speed and outputting the output is integrally connected to the upper portion of the motor 118. . At the center of the upper surface of the gear box 119, an output shaft 120 for outputting a reduced rotational force is vertically projected. Further, a square motor hole 42 is opened on the front side (the right rear side in FIGS. 5 and 8) of the holding plate 41 described above. The tool 121 is fixed by screws. The motor fixture 121 has a length slightly longer than the opening width of the motor hole 42, a cross-sectional shape of "U", and a foot portion extending horizontally at both ends. When the foot portions formed at both ends of the motor fixing tool 121 are brought into close contact with the upper surface of the holding plate 41, and each foot portion is fixed with a screw, the motor fixing tool 121 is fixed so as to close the motor hole 42. A circular opening 122 is formed in the center of the motor fixture 121, and the output shaft 120 is inserted above the opening 122 below,
When the upper surface of the gear box 119 is brought into close contact with the lower surface of the holding plate 41, the gear box 119 and the motor fixture 121 are attached.
Are connected by screws. Thus, the motor 118 and the gear box 119 can be fixed to the motor fixture 121.

When the gearbox 119 is fixed to the motor fixture 121 in this manner, the output shaft 120 projects vertically from the upper surface of the motor fixture 121. A pulley 123 is fitted into the output shaft 120 and the pulley 1
23 is set at the same height as the pulley 95 fixed to the drive shaft 76 (see FIG. 7). Then, an endless belt 124 made of rubber or the like is wound around the outer circumferences of the pulleys 95 and 123 (see FIGS. 5 and 7).
See FIG. 8). Although not shown in FIGS. 5 and 8, as shown in FIG. 7, a screw plate 125 protrudes from the upper surface of the holding plate 41 at a position close to the motor hole 42. A tension bolt 126 that can move in the horizontal direction is screwed into 125. The tip of the tension bolt 126 is in contact with the side surface of the motor fixture 121, and by turning the tension bolt 126, the motor fixture 121 can be moved horizontally in the horizontal direction in FIG. This tension bolt 126

By adjusting the tension of the belt 124, the rotational force from the motor 118 can be smoothly transmitted to the drive shaft 76.

[Configuration of Heating Unit 23]

The outer shape of the above-mentioned heating unit 23 is shown in FIGS.
This is shown by FIGS. The outer shape of the heating unit 23 is a flat box shape, and as shown in FIG.
5 is mounted on the upper surface of a pair of horizontal angles 46 held by the pair. The heating unit 23 mixes high-frequency electromagnetic waves into the drying pot 51 and the heat storage unit 60 by a high-frequency coil 128 serving as electromagnetic heating means housed therein, thereby generating eddy current loss in the drying pot 51 and the heat storage unit 60. Can generate heat. The heating unit 23 is assembled as a unit for generating electromagnetic waves, and the internal structure of the heating unit 23 will be described in detail with reference to FIG.

The outer shell of the heating unit 23 is constituted by a coiled container 129 having a hollow box shape inside.
It is composed of a lid plate 131 that closes the upper opening of 30. The box 130 is made of a thin metal plate and has a square bottom, and is formed in a square shape by standing up four sides of the bottom. The lid plate 131 is formed by cutting a thin metal plate into a square shape, and its planar shape is set to be slightly larger than the opening of the box 130. Therefore, when the cover plate 131 is put on the upper opening of the box body 130, the four corners of the cover plate 131 project horizontally,
The upper part of the coil container 129 projects right and left.
The lower surface of the lid plate 131 is brought into close contact with the opening of the box 130,
A single coil container 129 is assembled by screwing the two or joining them together by electric welding.
Reference numeral 9 denotes a configuration in which the inside is hollow and closed from the outside.

A flat cylindrical high-frequency coil 128 for generating an electromagnetic wave is housed in the center of the hollow interior of the coil container 129 as shown in FIG. Outer circumference and coil container 1
29 is fixed with some gaps so as not to contact the inner peripheral surface. A pair of power lines 132 for supplying power are connected to the high-frequency coil 128, and the ends of both power lines 132 are insulated and fixed to the side surface (the right front side in FIG. 13) of the box 130. Each is electrically connected to the electrode 133.

[Configuration of Attaching Foam Sensor 161]

Next, a foam sensor 161 for detecting the height of foam generated inside the drying pot 51 is attached to the holding plate 41 in the present embodiment. As shown in FIG. 8, the appearance of the foam sensor 161 has a cylindrical shape in which the lower half has a small diameter and the upper half has a large diameter. It is. The state where the foam sensor 161 is fixed to the holding plate 41 in this manner is shown in FIG. Inside the foam sensor 161, there is housed a mechanism for detecting the height of foam by generating ultrasonic waves, emitting the ultrasonic waves toward the bottom of the drying pot 51, and receiving the reflected ultrasonic waves.

[Detailed Configuration of Foam Sensor 161]

Next, FIG. 14 shows the bubble sensor 16 described above.
FIG. 1 is a side view of a state where 1 is attached to the drying unit 21, and shows a state in which the holding plate 41 and the drying pot 51 in the drying unit 21 are cut vertically around the sensor hole 65. . The foam sensor 161 is assembled as a single unit in which a detection part and a drive part are integrated. The appearance of this foam sensor 161 is as follows:
A cylindrical insertion tube 162 whose outer shape is substantially the same as the inner diameter of the shaft hole 61, a flange portion 163 protruding in an annular shape around the insertion tube 162, and connected to the upper portion of the insertion tube 162 and electrically connected inside. The main body 164 has a cylindrical shape with a larger diameter than the insertion tube 162 that accommodates the device. Due to this shape, when the insertion tube 162 is inserted into the sensor hole 65, the lower surface of the flange portion 163 adheres to the periphery of the upper end opening of the sensor hole 65 to close the sensor hole 65, and the insertion tube 162 becomes the lower surface of the holding plate 41. It can be suspended and fixed by a predetermined length. When the flange 163 is caught in the sensor hole 65 in this manner, the foam sensor 1
The main body 164 is held by the holding plate 41
It will be stood upright on the top of the to be fixed.

The lower surface of the insertion tube 162 is divided into two parts on the left and right. A transmitting part 165 for generating ultrasonic waves is provided on one lower surface (left side in the figure), and the other lower surface (in the figure). (On the right side), a receiving unit 166 for receiving an ultrasonic wave is provided, and both are arranged in parallel at an interval. The ultrasonic wave T is emitted from the transmitting unit 165 toward the bottom of the drying oven 51, and the emitted ultrasonic wave T is reflected on the surface of the foam N or the human waste W. The ultrasonic wave T reflected in the direction of the holding plate 41 is received by the receiving unit 166. Thus, the transmitting unit 1
The ultrasonic wave is emitted from 65 and the time when the reflected ultrasonic wave reaches the receiving unit 166 is measured, thereby measuring the height position of the upper surface of the bubble N and the liquid surface of the human waste W. You can do it.

[Configuration of Control System]

Next, as shown in FIG.
The configuration of a control system for automatically operating the entire system 5 will be described with reference to a block diagram. The entire human waste processing apparatus 15 is intensively controlled by a central processing circuit 231. The central processing circuit 231 is constituted by a CPU (microprocessor, central processing element, etc.) or a non-volatile memory (ROM) storing a program. It is configured. A predetermined procedure is stored in this non-volatile memory, and certain conditions can be determined to operate the human waste processing apparatus 15 in an optimal state. When bubbles are generated inside the drying pot 51 described above, it is possible to detect the occurrence and make a self-determination so as to automatically remove the bubbles.

The transmitting section 165 and the receiving section 166 housed in the foam sensor 161 are connected to the foam height detecting circuit 232. The bubble height detection circuit 232 outputs an operation instruction to the transmission unit 165 at regular intervals, and causes the transmission unit 165 to output ultrasonic waves. Then, the ultrasonic wave reflected from the bottom of the drying pot 51 is collected by the receiving unit 166, and the elapse of the time is transmitted from the receiving unit 166 to the foam height detecting circuit 232. In the bubble height detection circuit 232, the transmitting unit 165
After the emission instruction signal is output, the time for inputting the signal receiving the reflected wave from the receiving unit 166 is counted, and the height of the bubble N shown in FIG. 13 can be detected from this time difference. The signal of the height position of the bubble N detected by the bubble height detection circuit 232 is input to the central processing circuit 231, and the central processing circuit 231 is determined based on the height of the bubble N.
Has determined how to treat human waste. Although not shown in FIG. 1, an instruction switch 233 is provided inside the temporary toilet 11.
3 is connected to the drying instruction circuit 234. The instruction switch 233 is operated by a user who defecates using the toilet bowl 16 and instructs to start processing of excreted human waste. The output of the drying instruction circuit 234 is input to the central processing circuit 231. A power switch 2 for starting the entire operation of the urine processing apparatus 11 is provided.
The output of 30 is also input to the central processing circuit 231.

The central processing circuit 231 compares the input various signals with the conditions stored in advance as a program in the signals, and based on the result of the comparison, determines whether the signal is in the urine processing apparatus 1 or not.
1 can be operated.
Therefore, a plurality of control signals can be output from the central processing circuit 231, and the control signals of the central processing circuit 231 are input to the motor control circuit 235 and the heater control circuit 236. The motors 36 and 118 described above are independently connected to the motor control circuit 235. Also,
The heater control circuit 236 is connected to a reheater 237 and a high frequency generation circuit 238, and the high frequency generation circuit 238 is connected to a high frequency coil 128. The reheating heater 237 is housed in a reheating box (not shown) connected to the exhaust pipe 37 of the drying oven 51, and reheats the evaporated water vapor.

Next, the operation of the human waste processing apparatus 15 stored in the temporary toilet 11 of the first embodiment will be specifically described.

<Activation of the human waste processing apparatus 15>

When using the temporary toilet 11, the human waste processing apparatus 15 must first be set to a standby state.
For this reason, the administrator of the temporary toilet 11
Is set to a state where the human waste processing apparatus 15 is operated. Then, the central processing circuit 231 is activated and enters a standby state. When various signals are input, each mechanism operates according to the steps of a predetermined program. In this standby state, the central processing circuit 231 outputs a control signal to the motor control circuit 235 and the heater control circuit 236, and the motor control circuit 235 controls the motor 36.
, And the heater control circuit 236 causes the reheater 237 to generate heat. The motor 36 sucks air from the outside and supplies air to each mechanism. Further, when the reheating heater 237 generates heat, the catalyst housed in the deodorizing mechanism 18 is heated and maintained in a state capable of exhibiting the function of participating and reducing the factor of the malodor (actually, the human waste processing apparatus). The opening and closing valve and the switching valve must be operated at 15, but the description and operation thereof are omitted in this embodiment.)

<Use of temporary toilet 11 by user>

Next, a user who wants to excrete human waste using the temporary toilet 11 opens the door 14 and opens the house 1.
3 and excrete human waste to the toilet bowl 16.
The excreted human waste falls into the human waste treatment device 15 from a discharge port (not shown) opened in the lower part of the toilet bowl 16 and is heated in the human waste treatment device 15, and most of the water component is evaporated and dried. Is processed.

<Pouring of human waste into the drying pot 51>

Then, as shown in FIG. 2, the urine excreted toward the toilet 16 passes through the lower outlet of the toilet 16 and is guided further downward by the bellows-like joint 39. Then, it passes through an on-off valve (not shown) in the middle and flows down to the connection ring 55 to which the lower end of the joint 39 is connected. As shown in FIG.
Since the input port 56 is opened at the center of 5, the discharged human waste is input into the internal space of the introduction section 54 from the input port 56. Since the bottom surface of the introduction portion 54 is inclined toward the drying pot 51, the human waste flows in the inclined direction and flows into the internal space of the drying pot 51.
Although some of the human waste may adhere to the joint 39 or the inner wall of the introduction portion 54, a small amount of washing water is jetted from the tank (not shown) to the toilet 16 after the user defecates, and the human waste attached to the toilet is discharged. Can flow into the internal space of the drying pot 51 together with the washing water.

<Heating of the drying pot 51>

After the excrement is introduced into the drying oven 51, the drying oven 51 is heated to start a process of evaporating and drying the excrement. In this heating operation,
The user who excreted human waste manually instructs processing for the next user. For this reason, the user presses the instruction switch 233 to start the processing of human waste in the drying instruction circuit 2.
34, and the drying instruction circuit 234 is
5 informs the central processing circuit 231 that the process of evaporation / drying has been started. Then, the central processing circuit 231 transmits a control signal to the heater control circuit 236, operates the high-frequency generation circuit 238 by the heater control circuit 236, generates high-frequency power by the high-frequency generation circuit 238, and supplies high-frequency power to the high-frequency coil 128. I do. When electromagnetic waves are mixed by the high-frequency coil 128, a phenomenon of electromagnetic induction occurs in the drying pot 51 and the heat storage unit 60, and the drying pot 51 and the heat storage unit 60 generate heat by themselves. The high-frequency power supplied from the high-frequency generation circuit 238 is transmitted to the high-frequency coil 128 via the electrode 133 and the power line 132, and the high-frequency coil 128 generates an electromagnetic wave in the vertical direction. This high-frequency electromagnetic wave leaks out of the coil container 129, and the high-frequency electromagnetic wave passes through the bottom of the drying oven 51 approaching the upper surface of the coil container 129 and is mixed.

For this reason, a high frequency electromagnetic wave is mixed at the bottom of the drying pot 51, so that the phenomenon of electromagnetic induction heating occurs (the drying pot 51 is made of a metal material such as iron). The drying pot 51 itself generates heat. At the same time, this electromagnetic wave also mixes with the heat storage body 60 stored in the drying pot 51, and the heat storage body 60 itself also generates heat. Since the drying pot 51 and the heat storage unit 60 generate heat due to the electromagnetic induction heating, the human waste stored in the drying pot 51 is heated by the heating of the drying pot 51 and the heat storage unit 60, and the temperature rises. As the temperature of the night soil rises, the stored night soil is eventually heated to a boiling temperature, and the water, which is the major component of the night soil, evaporates from its surface as water vapor.

<Supply and exhaust of air from outside>

In this way, the human waste boils inside the drying pot 51, and the water, which is a major component of the waste, evaporates. However, when the on-off valve (not shown) is opened, it is already operating. Fresh air supplied from the blower 36 is injected into the drying pot 51 from the air supply hole 63. The oxygen contained in the external air supplied to the drying pot 51 is
Contact with boiling human waste to oxidize its components. At the same time, the water vapor and air evaporated in the drying pot 51 must be released to the outside. For this reason, the steam and the air evaporated from the exhaust hole 64 are caused to flow out of the drying pot 51. Then, the steam and the air flowing out of the exhaust holes 64 are heated by a reheating heater 237 in a reheating box through a flow path (not shown), and pass through the deodorizing mechanism 18 to oxidize and reduce components causing a bad odor. Is changed to an odorless state and released to the outside. As described above, the processing after the human waste is evaporated is a conventionally known configuration.

When the drying pot 51 is heated,
The water vapor generated from the drying pot 51 tries to squirt from the lower opening of the toilet bowl 16 through the joint 39 through the inlet 56, but an on-off valve (not shown) is provided in the middle of the joint 39 to evaporate the human waste. -During the drying process, the on-off valve is closed, so that the odor and steam do not blow out into the house 13 from the lower opening of the toilet 16.

<Rotary Motion of Stirring Unit 28>

As described above, when the instruction switch 233 is pressed, the drying oven 51 using the high-frequency coil 128 is pressed.
Simultaneously with the heating operation, the central processing circuit 231 causes the motor control circuit 235 to operate the motor 118 to start the stirring operation. When power is supplied to the motor 118,
The rotational output of the motor 118 is reduced in speed through the gear box 119, and the output shaft 120 at the upper end is rotated at a low speed. Then, the pulley 123 fixed to the output shaft 120 also rotates at the same time, and as shown in FIGS. 5, 7, and 8, the pulley 95 is driven via the belt 124, and is fixed to the center by the rotation of the pulley 95. The drive shaft 76 is rotated in the horizontal direction (the pulley 95
As shown in FIGS. 10 and 11, a key 97 is interposed between the drive shaft 76 and the drive shaft 76, so that the rotation in the horizontal direction does not slip, and the pulley 95 and the drive shaft 76 are synchronized. Rotate.) This drive shaft 76 is shown in FIGS.
Since the upper and lower portions are respectively held by bearings 84 and 91 fixed to the outer barrel 71 as shown by, the drive shaft 76 is maintained to rotate smoothly in the horizontal direction. As described above, when the pulley 95 is driven via the belt 124, the rotational force is transmitted to the drive shaft 76 via the key 97, and the pulley 95 and the drive shaft 76 rotate simultaneously in the same direction.

The lower part of the drive shaft 76 is shown in FIGS.
Since the stirring section 28 is suspended as shown in FIG. 9, the entire stirring section 28 rotates horizontally in the internal space of the drying oven 51 together with the drive shaft 76. In this rotation operation, the connecting plate 105 is connected to the connecting plate 78 fixed to the lower end of the drive shaft 76, and the connecting plate 105 includes a hanging pipe 107, an oblique pipe 108, and a suction pipe 109. Since the crank body 102 is suspended, the crank body 102 rotates in synchronization with the drive shaft 76 inside the drying pot 51. In this rotation operation, the suction pipe 109 rotates around the drive shaft 76 while drawing a circular locus in the drying pot 51. In the rotational movement of the suction pipe 109, the opening at the lower end of the suction pipe 109 is kept at such an interval that it does not contact the bottom of the drying pot 51, and the suction pipe 109 is connected to the drying pot 5.
1 can rotate without contacting the bottom surface.

When the suction pipe 109 rotates, the triangular plates 110 and 11 fixed to the side surfaces of the suction pipe 109 are rotated.
1 and the agitating plate 114 and the skirt plate 115 simultaneously perform a circular rotation in the drying pot 51. The rotation of the stirring plate 114 and the skirt plate 115 causes the stirring plate 114 to rotate.
Are slightly spaced apart from the inner wall of the drying pot 51, the lower end of the skirt plate 115 is slightly spaced from the bottom of the drying pot 51, and the stirring plate 114 and the skirt plate 115 are Rotate without contact. And the stirring plate 11
4. The skirt plate 115 is, as shown in FIG.
14. The space inside the drying pot 51 is divided into two by the skirt plate 115, and while maintaining this state, the stirring plate 114,
Since the skirt plate 115 rotates, the stirring plate 114 and the skirt plate 115 stir the human waste stored in the drying pot 51, and at the same time, push the heat storage body 60 housed in the drying pot 51 to rotate. It will roll.

<Stirring of Human Waste by Heat Storage Body 60>

When the motor 118 operates as described above,
By the rotation output, the entire stirring unit 28 is rotated,
The heat storage body 60 charged into the drying pot 51 is rolled inside the drying pot 51 by the stirring plate 114 and the skirt plate 115. The sewage housed in the drying pot 51 is agitated by the stirring plate 114 and the skirt plate 115 and the heat storage body 60 is rolled at the same time. And the mixture is stirred so that the temperature of the whole excrement rises uniformly. When the heat storage elements 60 are rolled, human waste is adhered to the surface of each heat storage element 60, and
The heat which is generated is transmitted to the excrement, and serves to help increase the temperature of the excrement. Thus, human waste is stored in the heat storage body 60.
While being stirred, the temperature at which the heat is generated is transmitted, and the temperature of the whole human waste is raised.

<Detection of Foam Generated Inside Drying Kettle 51>

As described above, the drying pot 51 containing the human waste W is contained in the drying pot 51.
When water is heated, the water in the human waste is boiled and evaporated, but at the same time, bubbles N are generated by the components contained in the human waste W as shown in FIG. The foam N accumulates above the liquid level of the excrement W and its height gradually increases. Then, the foam N fills the inside of the drying pot 51, and the foam N flows out from the exhaust hole 64 from which water vapor normally flows out,
It will flow into the reheating box and the deodorizing mechanism 18. If the state is out of the original purpose, the steam cannot flow out, and the reheating box and the deodorizing mechanism 18 may be broken down.

Now, when the central processing circuit 231 is operating, the detection signal from the bubble height detecting circuit 232 is always input, and the central processing circuit 231 always grasps the height position of the bubble N shown in FIG. doing. That is, the bubble height detection circuit 23
2 constantly operates the transmission unit 165 to emit the ultrasonic wave T toward the bottom of the drying pot 51. Then, the receiving unit 16
Numeral 6 receives a reflected wave from which the emitted ultrasonic wave T is reflected by the surface of the bubble N. The foam height detection circuit 232
The time from when the transmitting unit 165 is activated to when the reflected wave is received by the receiving unit 166 is counted, and the distance from the lower surface of the bubble sensor 161 to the surface of the bubble N is determined by the delay of this time. Central processing circuit 2 using the detection result as a signal
31. For this reason, when the surface of the foam N becomes high and becomes a height that is inconvenient in the treatment of human waste,
Based on the detection signal from the bubble height detection circuit 232, the central processing circuit 231 instructs to change the processing so that the height of the bubble N is reduced.

<Removal of Bubbles Generated Inside Drying Kettle 51>

As described above, when the central processing circuit 231 determines that the surface of the bubble N has become high and a dangerous state has occurred, the central processing circuit 231 sends a control signal to the heater control circuit 236 to stop the temporary heating. Tell Then, the heater control circuit 236 suspends the operation of the high-frequency generation circuit 238, and stops the supply of the high-frequency power from the high-frequency generation circuit 238 to the high-frequency coil 128. Then, the mixing of the electromagnetic wave from the high-frequency coil 128 to the drying pot 51 is stopped, the drying pot 51 is not heated, and the temperature of the drying pot 51 decreases with time. Drying pot 51
When the temperature in the inside is reduced, the bubbles N are naturally reduced and liquefied and dissolved in the excrement W, the height of the foam N is reduced, and finally the liquid level of the excrement W becomes the level. In this way, once the human waste W is boiled and the foam N is generated and then liquefied, the components to be the foam are volatilized. No longer.

After the operation of the high frequency generator 238 is stopped by the central processing circuit 231, a certain time
(Set in accordance with the volume of waste, the quality of human waste, etc.), it is determined that the bubbles N have disappeared, and the process of evaporating and drying the human waste is started again. That is, the central processing circuit 23
Reference numeral 1 denotes a high-frequency generation circuit 2 through a heater control circuit 236.
The operation of 38 is restarted, high-frequency electromagnetic waves are mixed in the drying pot 51, and electromagnetic induction heating is performed. As mentioned above, human waste W
Is cooled after being boiled, so that the elements that generate the bubbles N are diffused, so that the bubbles N will not be generated from the surface of the human waste W even if they are heated again.

<End of Processing for Evaporation and Drying of Manure by Drying Kettle 51>

By rotating the stirring unit 28 while heating the drying pot 51 and the heat storage unit 60 with the high-frequency coil 128 in this way, the night soil stored in the drying pot 51 continues to boil, and most of the night soil components Moisture continues to evaporate. If this evaporating operation is continued, finally the drying pot 5
All of the human waste stored in 1 will be evaporated. When all the human waste in the drying pot 51 has evaporated, it is not necessary to heat the drying pot 51 and the heat storage body 60 by the high-frequency coil 128, and the evaporating and drying process must be completed. The end of this operation can be automatically performed by detecting a rise in the temperature of the drying pot 51 by a temperature sensor (not shown). That is, the temperature change on the side surface of the drying pot 51 is constantly monitored by a temperature sensor (not shown), and when excrement is present in the drying pot 51, the temperature of the drying pot 51 is maintained near the boiling point. The temperature does not rise. However, when all the human waste is evaporated, the drying pot 51
Is rapidly increased, and by detecting the change in the temperature with the temperature sensor, it can be determined that all the human waste in the drying pot 51 has been evaporated.
When it is determined by the temperature sensor that the evaporation of the human waste in the drying pot 51 has been completed, the central processing circuit 231
Outputs a heating operation stop signal to the heater control circuit 236. Therefore, the operation of the high frequency generating circuit 238 is stopped by the heater control circuit 236 and the high frequency coil 128 is stopped.
The operation of heating the drying pot 51 and the heat storage unit 60 by the high-frequency coil 128 is stopped.

<Cleaning Process of Drying Kettle 51>

[0148] When all the human waste stored in the drying pot 51 is evaporated and dried in this manner, most of the water component is evaporated, but the organic and inorganic substances contained in the human waste become dust. It will remain in the drying pot 51. When such dust adheres and accumulates on the inner wall and the bottom of the drying pot 51, the stirring plate 114, the skirt plate 115, and the heat storage unit 60 cannot rotate in the drying pot 51 due to long-term use. Will not be able to perform the processing function. For this reason, when the processing of evaporating and drying the human waste has been completed, the processing of cleaning the inside of the drying pot 51 must be performed next to remove dust remaining in the drying pot 51.

In the cleaning process, the motor 11
By rotating the agitating section 28 with the use of the air 8, air can be sucked from the upper end opening of the ventilation hole 77 provided in the drive shaft 76. That is, suction is started by a suction device connected to the valve 38 (the suction side of the blower 36 is connected by a communication pipe), and when the valve 38 is opened, the air in the ventilation hole 77 is discharged through the exhaust pipe 37. It will be aspirated. Then, a suspension pipe 107 constituting the crank body 102 connected to the lower end of the drive shaft 76,
Since the inclined pipe 108 and the suction pipe 109 communicate with the ventilation hole 77, air is sequentially sucked from the lower end opening of the suction pipe 109. When the air is sucked from the lower end opening of the suction pipe 109, dusts such as non-evaporable organic and inorganic substances remaining near the bottom of the drying pot 51 are sucked together with the air from the lower end opening of the suction pipe 109. Then, the dust sucked together with the air flows into the suction pipe 109,
Oblique pipe 108, hanging pipe 107 and ventilation hole 7
7 and is discharged from the drying pot 51 to the outside. The dust sucked together with the air is discharged to the exhaust pipe 37, the valve 3
8, the dust is captured by a dust separator (not shown) (having the same structure as a garbage bag in a vacuum cleaner), and the air is separated and cleaned to be discharged to the outside.

During the cleaning process, the motor 118 continues to operate, and the entire agitating section 28 is moved through the pulley 123, the belt 124, and the pulley 95 in the drying kettle 51 like a miso rubbing motion. It rotates in a circular path. For this reason, the lower end opening of the suction pipe 109 rotates in a circular shape near the bottom of the drying pot 51, so that dust accumulated on the bottom of the drying pot 51 can be sucked up evenly.
When the stirring unit 28 rotates, the stirring plate 114 and the skirt plate 115 also rotate, and the heat storage unit 60 is rolled at the bottom of the drying pot 51. Therefore, the dust accumulated on the bottom of the drying pot 51 is removed by the heat storage unit 60. In addition to removing the dust, the dust is finely crushed, and the dust accumulated at the bottom of the drying pot 51 is peeled off and finely crushed so as to be easily sucked together with air.

<Stop of cleaning process>

By sucking the dust stored in the drying pot 51 in this way, the cleaning processing of the drying pot 51 can be performed. If this processing is continued for a predetermined time, the cleaning processing is performed. Complete. When the cleaning process is stopped, the motor 118 stops its operation, the stirring unit 28 stops without rotating, the valve 38 is closed, and the blower 3
6 will stop. Then, when the cleaning process is completed, each mechanism constituting the human waste processing apparatus 15 maintains its state and waits, and waits for a user who wants to use the temporary toilet 11 next and excrete the toilet 16. I do. By repeating such a series of cycles sequentially, the temporary toilet 1
Human waste excreted in one toilet bowl 16 can be treated without odor.

[Second Embodiment]

Next, FIG. 16 shows a second embodiment using another foam sensor 171 having a different structure from the foam sensor 161 in the above-described first embodiment. The outer shape of the foam sensor 171 is cylindrical, and the outer diameter thereof is substantially the same as the inner diameter of the sensor hole 65. An insertion tube 172, a flange portion 173 fixed in a ring shape in the middle of the insertion tube 172, It is formed by a main body 174 having a large outer diameter connected to the upper end of the cylinder 172, and is configured as an integral unit. When the lower portion of the insertion tube 172 is inserted into the sensor hole 65, the lower surface of the flange portion 173 contacts and locks the upper surface of the holding plate 41, and the sensor hole 65 is closed. A pair of electrode rods 175 and 176 are fixed to the lower surface of the insertion tube 172 in parallel downward.
The electrode rods 175 and 176 are each formed of a highly conductive metal material such as copper or brass, and are electrically insulated from each other. For this reason, the electrode rods 175 and 176 are respectively arranged vertically toward the bottom of the drying pot 51, and are spaced apart from the surface of the human waste W in the upper space of the drying pot 51.

In this embodiment, a pair of electrode rods 17
The height of the bubble N is detected by the electrical conduction of 5, 176. That is, when electromagnetic waves from the high-frequency coil 128 are mixed and heated at the bottom of the drying unit 21, the human waste W boils,
Bubbles N are generated from the surface of the human waste W. As the human waste W continues to boil, the bubbles N are sequentially stacked upward and the surface thereof rises. In the normal processing, the lower ends of the electrode rods 175 and 176 are not in contact with the liquid surface of the human waste W, and are in an insulated state.
No current flows between them. However, as the bubble N rises, the bubble N eventually comes into contact between the lower ends of the electrode rods 175 and 176. Then, the electrode rods 175 and 176 become conductive via the bubbles N, and a small amount of current flows. By detecting this minute change in current, it can be determined that the bubbles N generated from the surface of the human waste W have risen to a predetermined height. When such a state is detected, the bubble sensor 171 outputs a signal to the central processing circuit 231 that the bubble N has reached a position higher than a predetermined height, as described above, and the central processing circuit 231 The supply of high frequency power to the power supply 128 is temporarily stopped. Then, the heating of the drying pot 51 by the electromagnetic wave is stopped, and the bubbles N generated from the excrement W are liquefied.
And the bubbles N can be removed.

[Third Embodiment]

FIG. 17 shows the bubble sensor 16 described above.
Reference numerals 1 and 171 denote a mechanism of the bubble sensor 181 according to the third embodiment for detecting the height position of the bubble N based on another principle. The outer shape of the bubble sensor 181 is cylindrical, and the outer diameter thereof is substantially the same as the inner diameter of the sensor hole 65. An insertion tube 182, a flange portion 183 fixed in a ring shape in the middle of the insertion tube 182, It is formed by a main body 184 having a large outer diameter connected to the upper end of the cylinder 182, and is configured as an integral unit. This insertion tube 182
Is inserted into the sensor hole 65, the lower surface of the flange portion 183 contacts and locks the upper surface of the holding plate 41, and the sensor hole 65 is closed. Since this insertion tube 182 is formed of an electrically insulated material, the holding plate 41 and the insertion tube 182
No current flows, and the lower surface of the insertion tube 182 is formed flat, and an electrode plate 185 formed of a copper plate or the like is fixed to the lower surface. An output terminal 186 is fixed to the upper surface of the main body 184, and the output terminal 186 is electrically connected to the electrode plate 185.
6, a positive high potential is applied. And the holding plate 4
A ground terminal 187 is fixed to the upper surface of the reference numeral 1, and a voltage of zero or a negative potential is applied to the ground terminal 187.
These output terminal 186 and ground terminal 187 are connected to a bubble height detection circuit for detecting a change in dielectric capacitance (capacitance) not shown.

In this embodiment, the height of the bubble N can be detected by a change in the dielectric capacitance (capacitance) generated in the electrode plate 185. That is, when electromagnetic waves from the high-frequency coil 128 are mixed and heated at the bottom of the drying unit 21, the human waste W boils, and bubbles N are generated from the surface of the human waste W. As the human waste W continues to boil, the bubbles N are sequentially stacked upward and the surface thereof rises. A negative potential or zero potential is applied to the foam N from the ground terminal 187 via the holding plate 41, the drying pot 51, and the human waste W. Then, the dielectric capacitance between the electrode plate 185 to which the high voltage positive potential is applied and the surface of the bubble N fluctuates, and compared with the dielectric capacitance between the surface of the human waste W and the electrode plate 185. Its capacity increases. That is, when the upper surface of the bubble N rises and the distance between the electrode plate 185 and the electrode plate 185 becomes shorter, the dielectric capacitance increases. By detecting a change in the dielectric capacitance between the output terminal 186 and the ground terminal 187, the bubble N becomes the electrode plate 1
85 can be determined. Thus, the height position of the bubble N can be detected by determining the change in the dielectric capacitance. When the bubble N rises to a predetermined height, the bubble sensor 181 determines the bubble N in advance as described above. The central processing circuit 231 outputs a signal to the central processing circuit 231 that the position has become higher than the set height.
The supply of high-frequency power to the high-frequency coil 128 from 1 is temporarily stopped. Then, the heating of the drying pot 51 by the electromagnetic wave is stopped, and the foam N generated from the human waste W is liquefied, and the foam N
Is settled in the human waste W, and the bubbles N can be removed.

[Fourth Embodiment]

Next, FIG. 18 shows a fourth embodiment of the present invention. In this embodiment, the foam N generated from the inside of the drying pot 51 is guided to the defoaming mechanism 191 using a water-sealed tank, and the foam is reduced to a liquid state, whereby the foam can be removed. . Hereinafter, the configuration in the present embodiment will be described with reference to the drawings.

In this embodiment, the aforementioned holding plate 41
Is a foam steam pipe 192 for introducing foam N to the outside together with water vapor.
Are connected at one end. The foam steam pipe 192 has a pipe shape, and is entirely bent so as to have an inverted U-shape.
One of the three openings is connected. This water seal tank 193
Has a hollow U-shape with both ends open upward when viewed from the side, and a foam steam pipe 1 at one end.
The other end of 92 is connected. A discharge pipe 194 is connected to the other end of the foam steam pipe 192, and the discharge pipe 194 extends upward.
The upper end of 94 is connected to a joint 195 for communicating with a reheating mechanism, a deodorizing mechanism, and the like. This water-seal tank 193 has a U-shape when viewed from the side, and its central horizontal part is elongated, and this central part is a closed tank shape. One end of a water guide pipe 196 is connected to the center of the bottom of the water seal tank 193.

The water guide pipe 196 extends horizontally and then extends upward to form a siphon pipe 197. The upper end of the siphon pipe 197 is open. A water storage box 198 having a hollow inside and a somewhat large shape is fixed to the outer periphery of the end of the siphon pipe 197, and the terminal opening of the siphon pipe 197 is located near the center of the inside of the water storage box 198. It is. A drain pipe 19 is provided at the bottom of the water storage box 198.
9 is connected, the drain pipe 199 extends vertically downward, and a collection box 200 for collecting water is located near the lower end opening. And
The inside of the water seal tank 193 described above is filled with water M, and the surface of the water M is at the same height position as the upper end opening of the siphon pipe 197 described above.
3 is higher than the ceiling. Therefore, the water seal tank 1
Most of the internal space of 93 is filled with water M, and the water M is filled up to both ends of the “U” shape. As described above, when the water M is filled in the water seal tank 193, the foam steam pipe 192 and the discharge pipe 194 do not directly communicate with each other, and the water M is interposed between the two. These water seal tank 193, discharge pipe 19
4. The water guide pipe 196 and the water M constitute a defoaming mechanism 191.

In this embodiment, when the drying unit 51 is heated by the heating unit 23, the human waste W stored inside the drying unit 51 boils, and steam is generated from the surface of the human waste W. In addition, foam N is generated from the surface by the components contained in the human waste W, and the foam N fills the internal space of the drying pot 51. When the drying unit 51 is continuously heated by the heating unit 23, the foam N fills the space above the drying unit 51,
It will flow out of the drying pot 51 from the foam steam pipe 192. The foam N flowing out of the foam steam pipe 192 flows inside the foam steam pipe 192, and then flows into the water seal tank 193 sequentially. Since water M is contained inside the water seal tank 193,
When the bubble N comes into contact with the water M, the bubble N is reduced to a liquid by the cold water M. However, the steam generated from the human waste W stored in the drying pot 51 moves toward the water seal tank 193 through the foam steam pipe 192. The water vapor pushes down the water M into the water seal tank 193 by the pressure and flows out from the discharge pipe 194. Therefore, even if the water vapor and the foam N are mixed and flow into the water seal tank 193, the foam N is all reduced to the liquid by the water M, and only the water vapor is discharged to the discharge pipe 194 and the joint 1.
It is transferred to the next processing step via 95.

Then, the bubbles N come into contact with the water M and are reduced to a liquid. The volume of the liquid bubbles N increases the volume of the water M. As the volume of the water M increases, the water level increases. However, since the height of the water surface is limited to the position of the upper end of the siphon pipe 197, the increase in the volume of the water M increases by the upper opening of the siphon pipe 197. Out of the water storage box 198 and drain pipe 199
It flows down further and flows into the collection box 200. In this way, all the components of the foam N generated are changed to liquid and collected in the water storage box 198, so that the foam N
Is generated in the water sealing tank 193, and the bubbles N are not moved to the reheating mechanism or the deodorizing mechanism following the joint 195. When the human waste W boils for a certain period of time, the components that generate the bubbles N are volatilized, so that the bubbles N are no longer generated, and only the steam is generated from the inside of the drying oven 51. The water vapor pushes down the water M, passes through the inside of the water seal tank 193, and flows through the discharge pipe 194 and the joint 195, so that there is no hindrance to the operation of evaporating the human waste W.

[Fifth Embodiment]

Next, FIG. 19 shows a fifth embodiment of the present invention. In this embodiment, the bubbles N generated from the inside of the drying pot 51 are guided to the defoaming mechanism 205, and the defoaming mechanism 205 can spray water like a shower to reduce the bubbles N to a liquid.

In this embodiment, the holding plate 41 described above is used.
Has a foam steam pipe 20 communicating with the internal space of the drying pot 51.
6 and the foam steam pipe 206 is connected to the holding plate 4
It extends vertically from 1 and is bent horizontally at the top. At the end of the foam steam pipe 206,
A closed shower box 207 having a hollow inside is connected. The shower box 207 has a sufficient volume to allow the bubbles N to flow in, and its bottom is inclined toward the center like a funnel. And on the upper surface of the shower box 207, the exhaust pipe 212 is extended upward.
A joint 213 communicating with the reheating mechanism and the deodorizing mechanism is connected to the exhaust pipe 212. A shower nozzle 208 for spraying water is fixed at the center of the ceiling of the shower box 207, and a suction pipe 209 extends downward at the center of the bottom of the shower box 207. The end of the suction pipe 209 is connected to a water pump 210. The water pump 210 is driven by a motor or the like, and a drain pipe 211 is connected to the discharge side thereof.
8 is connected. Then, water Q is injected into the inside of the shower box 207, and the liquid level of the water Q is set to be about １ ／ from the bottom of the shower box 207. These shower box 207, shower nozzle 208, suction pipe 209, water pump 210, drain pipe 211, water Q
Constitutes the defoaming mechanism 205.

In this embodiment, when the drying unit 51 is heated by the heating unit 23, the human waste W stored inside the drying unit 51 boils, and steam is generated from the surface of the human waste W. In addition, foam N is generated from the surface by the components contained in the human waste W, and the foam N fills the internal space of the drying pot 51. When the drying unit 51 is continuously heated by the heating unit 23, the foam N fills the space above the drying unit 51,
It flows out of the drying pot 51 from the foam steam pipe 206. The foam N flowing out of the foam steam pipe 206 flows inside the foam steam pipe 206, and the shower box 2
07. Simultaneously with the heating of the drying kettle 51, the water pump 210 has already been operated, and the water Q is sucked from the suction pipe 209 and is being pumped toward the drain pipe 211. The water Q is ejected from the shower nozzle 208, and the water Q is sprayed into a space in the shower box 207 like a shower.

Then, when the foam N flows from the foam steam pipe 206 into the shower box 207, the foam N
07 will float on the surface of the water Q stored in the storage unit 07. At this time, since the water Q is sprayed in a fine mist state in the space of the shower box 207, the water is physically jetted to the bubbles N to be destroyed, changed to a liquid, and mixed with the water Q.
By driving the water pump 210 in this manner, the water Q is constantly sprayed from the shower nozzle 208 to physically destroy the bubbles N. The water vapor evaporated from the human waste W passes through the foam vapor pipe 206, the upper space of the shower box 207, and the exhaust pipe 212, and then passes through the joint 213.
It will move to the next processing step.

[Sixth Embodiment]

FIGS. 20 and 21 show a sixth embodiment of the present invention. In this embodiment, the bubbles N generated from the inside of the drying pot 51 can be destroyed and eliminated by the defoaming mechanism 221 using a wire mesh.

The above-mentioned holding plate 41 has a bubble vapor pipe 2 for flowing the vapor N and the vapor N evaporated from the human waste W.
22 is connected. The foam steam pipe 222 is formed by bending the pipe slightly in a Z-shape. The middle portion is inclined toward the drying pot 51, and the opening at the other end is directed upward. Next, the defoaming mechanism 221 is formed by a defoaming box 223 having a hollow inside, an intake pipe 225 connected to the bottom surface thereof, and an exhaust pipe 226 communicating with the upper space. As shown in FIG. 21, the defoaming box 223 has a cylindrical outer shape, has a flat shape with a flat top and bottom, and has a funnel-shaped bottom portion inclined toward the center. A downwardly directed intake pipe 225 is connected to the center of the bottom surface of the defoaming box 223,

Numeral 24 is circular, and the periphery of the wire mesh 224 is fixed to the inner wall of the defoaming box 223 so as to separate the space above and below the defoaming box 223. The wire mesh 224 is formed by knitting a thin metal wire with a material such as copper, brass, or platinum.

In this embodiment, when the drying unit 51 is heated by the heating unit 23, the human waste W stored inside the drying oven 51 boils, and steam is generated from the surface of the human waste W. In addition, foam N is generated from the surface by the components contained in the human waste W, and the foam N fills the internal space of the drying pot 51. Then, the foam N rises through the foam vapor pipe 222 connected to the holding plate 41 and the intake pipe 225
It will flow into the lower space of the defoaming box 223 more. However, in the center of the space of the defoaming box 223, a wire mesh 224 is provided.
Is placed horizontally, the rising bubbles N come into contact with the wire mesh 224 and are retained there. Simultaneously with the inflow of the foam N, the steam evaporated from the drying pot 51 flows into the defoaming box 223 and passes through the gap of the wire mesh 224. Then, the bubbles N caught on the wire mesh 224 are physically ruptured when the steam flows, and are reduced to a liquid. The components of the foam N that has become liquid are the intake pipe 225 and the foam steam pipe 2.
It flows down below 22 and flows into the drying pot 51, so that it is mixed with the human waste W. By repeating this operation, even if bubbles N are generated from the excrement W, the bubbles N are captured by the wire netting 224 and reduced to liquid, so that they do not flow in the direction of the exhaust pipe 226.

[Seventh Embodiment]

FIG. 22 shows a seventh embodiment of the present invention. In this embodiment, the foam N can be eliminated by spraying the defoaming agent into the inside of the drying pot 51 to reduce the surface tension.

The holding plate 41 has a bubble sensor 161.

Can be. A nozzle 241 is fixed to the holding plate 41, and the opening of the nozzle 241 is directed to the internal space of the drying pot 51. The nozzle 241 can spray the liquid in a mist. Further, a closed liquid tank 242 is housed in the human waste processing apparatus 15, and the liquid tank 242 is positioned above the drying pot 51. An antifoaming agent 247 (for example, a chemical such as a surfactant) is stored inside the liquid tank 242, and a communication pipe 243 for discharging the antifoaming agent 247 is connected to the bottom side surface of the liquid tank 242. It is. A pressure pump 244 is connected to the end of the communication pipe 243.
A liquid feed pipe 245 is connected to the output side of the pressure feed pump 244.

A liquid level sensor 246 is provided close to the bottom of the inside, and this liquid level sensor 246 can detect that the liquid level of the antifoaming agent 247 has fallen and issue an alarm.

Next, the operation of this embodiment will be described. When the drying pot 51 is heated by the heating unit 23, the waste W stored in the drying pot 51 boils, and steam is generated from the surface of the waste W. In addition, foam N is generated from the surface by the component contained in the human waste W, and this foam N
Will fill the interior space. The height of the bubble N is detected by the bubble sensor 161. When the top of the bubble N is lifted to a predetermined height, the bubble sensor 161 detects the height and transmits a signal to the pump 244. This signal causes the pump 244 to start operating, and the communication pipe 243

Since the antifoaming agent 247 sprayed on 1 adheres to the upper surface of the foam N and reduces the surface tension, each foam N cannot maintain the tension and bursts and disappears. When the foam N ruptures and the foam N does not exist inside the drying pot 51, the sprayed defoamer 247 covers the surface of the human waste W,
Even if the human waste W is heated, the surface tension on the surface thereof is reduced, thereby preventing the generation of bubbles N again.

As described above, if the pump 244 operates according to a command from the foam sensor 161, the pump 244 stops its operation after a predetermined time has elapsed, and does not pump the defoamer 247 any more. . For this reason, once the bubbles N are generated inside the drying pot 51, the required minimum amount of the antifoaming agent 247 is sent to the drying pot 51, and the antifoaming agent 247 covers the surface of the human waste W. The amount of the antifoaming agent 247 injected at a time is set by the volume of the drying pot 51,
Try not to inject unnecessary amounts.

As described above, according to the first aspect of the present invention, a foam sensor for detecting the height of foam is provided inside a container for storing human waste, and the foam sensor detects the height of the foam from the human waste. The height of generated bubbles is constantly detected. And
When the height of the foam exceeds the allowable height, the foam sensor transmits the signal to the control mechanism, and the control mechanism temporarily stops the operation of the heating means for heating the container and interrupts the heating. Then
Since the temperature of the container is reduced and the temperature of the night soil is reduced, the generated bubbles are reduced and the height is reduced. And
Since the foam is liquefied and the components that generate the foam are volatilized and removed from the human waste, the foam is not generated even if the container is heated again after a predetermined time has elapsed. As described above, once bubbles are generated inside the container, if the temperature of the container and the human waste is lowered, the bubbles will not be generated even if the human waste is heated next time. Can be.
In addition, since the bubbles do not flow out to the reheating mechanism or the deodorizing mechanism, which is the next processing mechanism, it is possible to eliminate the cause of the failure due to the adhesion of the bubbles to these mechanisms.

According to the invention of claim 2 of the present application, the foam sensor emits an ultrasonic wave in the direction of the liquid level of the human waste and detects a reflected wave of the ultrasonic wave reflected from the surface of the foam.
The height of the foam can be detected. Since the height of the foam is detected by ultrasonic waves, the sensor does not directly contact the foam,
Long-term use is possible. Further, the height of the bubble can be accurately detected by detecting the time difference between the irradiation wave and the reflected wave, and the setting of the height position at which the bubble is to be removed can be electrically changed. Therefore, the height position of the foam at which the heating of the human waste is stopped can be freely changed depending on conditions such as the quality and temperature of the human waste to be processed.

According to the invention of claim 3 of the present application, the foam sensor is constituted by a pair of electrodes, and it is possible to detect the height of the foam by contact between the electrodes and electrical conduction. it can. With this configuration, the foam sensor can be easily manufactured, and the structure is strong and simple, so that a malfunction does not occur due to a change in impact or the like.

According to the invention of claim 4 of the present application, the foam sensor can detect the height of the foam by changing the dielectric capacitance (capacitance) between the electrode provided on the container and the human waste. . In this configuration, since there is no driving portion and a change in the dielectric capacitance can be electrically processed and detected by applying a potential, long-term use is possible.

According to the invention of claim 5 of the present application, a water-sealed tank is connected to the container, and the water-sealed tank is filled with water. In this configuration, the water vapor and bubbles generated from the container can be brought into contact with the water in the water seal tank and then flow to the next processing mechanism, and the bubbles are liquefied by contact with the water,
Only water vapor can be transferred to the next processing mechanism.
The bubbles can be eliminated only by bringing the bubbles into contact with the water in the water seal tank, and the disappearance of the bubbles can be reliably performed.

According to the invention of claim 6 of the present application, a siphon pipe is connected to the bottom of the water seal tank, and the other end of the siphon pipe has an opening at the liquid level of the water stored in the water seal tank. It has been set. For this reason, even if the volume of water in the water seal tank increases due to the volume of bubbles liquefied by contact with water, the increased liquid volume flows out from the other end opening of the siphon pipe, and the water inside the water seal tank The height of the liquid level in the water can always be kept constant. Further, since the volume of the liquefied foam can be automatically collected, the defoaming mechanism can be used for a long time.

According to the invention of claim 7 of the present application, a shower box is connected to a container, and the shower box is provided with a shower head for spraying water. With this mechanism, water vapor and bubbles generated from the container flow into the shower box, but the bubbles collide with water sprayed from the shower head and are physically destroyed and liquefied. In addition, since the steam can flow between the sprayed water, there is no resistance to the flow, and the steam can smoothly move to the next processing mechanism.

According to the invention of claim 8 of the present application, a defoaming box containing a wire mesh is arranged at a position higher than the container, and a foam steam pipe for flowing steam and bubbles is provided between the container and the defoaming box. It is a configuration that communicates. With this structure, bubbles and water vapor generated from the container flow into the defoaming box while rising from the foam vapor pipe, but when the foam comes into contact with the wire mesh installed in the defoaming box, the foam is physically repelled and liquefied. The liquid foam then flows down the foam vapor pipe and flows back into the vessel. Then, only the steam can pass through the wire mesh and move to the next processing mechanism, so that it does not hinder the movement of the steam. In addition, when water vapor passes through the wire mesh, the bubbles captured by the wire mesh are ruptured and pass through, so the bubbles and the water vapor flow simultaneously to the defoaming box, so that the bubbles are efficiently eliminated. Can be.

According to the ninth aspect of the present invention, when bubbles are generated inside the container, the generation of the bubbles can be detected by the bubble sensor, and the defoaming agent can be sprayed into the container. The antifoaming agent can reduce the surface tension of the foam and human waste, so that even when the human waste is heated, the foam does not occur again.
