[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable toilet having a container for receiving excrement and disassembling the excrement in the container.

[0002]

2. Description of the Related Art As a prior art of a toilet for treating this kind of excrement, there is a technique disclosed in Japanese Patent Publication No. 2-48320.

[0003] That is, the technique disclosed in the above-mentioned gazette is based on a human waste inlet provided with a human waste introduction port, a human waste intake port dispersed at a position arbitrarily away from the human waste introduction port, and an appropriate switching means provided inside. In the storage tank, an intake port connected to a blower and an exhaust port connected to an exhaust fan are provided, and a heater is provided at an appropriate position of an air supply path leading to the air supply port and an appropriate place in the night soil storage tank. The present invention relates to a human waste separation apparatus for controlling the temperature of human waste in a tank by setting the temperature of the human waste at or near 50 degrees as a set temperature.

[0004] The human waste decomposition apparatus thus constructed is capable of decomposing human waste by improving the fermentation environment of high-temperature fermentative bacteria.

[0005]

The above-mentioned conventional human waste disintegrating apparatus is disposed below a toilet in an individual house, and is large in size and cannot be used easily.

However, portable toilets for storing excrement of infants, elderly people, and persons requiring care do not have a concept of treating excrement in the portable toilet.

In a general portable toilet, a toilet bowl for a poly bucket is provided under the toilet seat where the buttocks are placed, and after use (after excretion)
It is necessary to remove the toilet tub and dispose of the excrement in Haki and wash the toilet tub, which makes the treatment after excretion cumbersome and has a hygienic problem.

[0008] In particular, when a paper bucket is used to store the excrement of a portable toilet, the paper bucket containing the excretion needs to be disposed of as combustible garbage. The practice of putting them in a deodorant bag for a few days and disposing them at the time of collection of garbage means that there is resistance in storing the garbage in the home until the garbage is removed as garbage from the home, and there is a feeling of filth. there were.

Therefore, there is a need for a portable toilet that can treat excrement and does not emit odor.

In addition, there is a possibility that the handler of the portable toilet containing the excrement of an infant, an elderly person, or a person requiring care may be directly used by an infant, an elderly person, or a person requiring care. It is necessary to facilitate handling, and it is necessary to perform the control operation required for the portable toilet in the normal use operation.

[0011] Therefore, the present invention provides a portable toilet which can efficiently treat excrement, can be used without emitting odor, and can be used without the user having to operate a special control switch. This is an issue.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a portable toilet according to the present invention will be described below.

[First Embodiment] FIG. 1 is a perspective view showing an entire portable toilet according to a first embodiment of the present invention.
2 is a cross-sectional view showing the structure of the portable toilet of the first embodiment of the present invention, and FIG. 3 is a cross-sectional view showing the attachment structure of the toilet lid of the portable toilet of the first embodiment of the present invention. , (A) and (b) show two examples of the mounting structure.

In FIG. 1, the seat portion 2 has an upper opening 2a on which the buttocks are placed, and the base portion 3 serves as an overall base and has an armrest portion 3a. The toilet lid 5 is pivotally supported by the seat portion 2 and can open and close the upper opening 2a.

As shown in FIG. 3A, in the upper opening 2a of the seat 2, a toilet lid 5 for opening and closing the upper opening 2a is rotatably supported by a rotary shaft 5a fixed to the seat 2. It is supported. In addition, in a part of the periphery of the rotating shaft 5a of the toilet lid 5,
The stepped portion 5b has a stepped portion formed by rapidly expanding the diameter from the rotating shaft 5a, and the stepped portion 5b is the hollow portion 2 of the toilet lid 5.
b is rotated, and the stopper 2 of the seat 2 is rotated by the rotation.
It contacts with c and regulates the rotation of the toilet lid 5. The rotation of the toilet lid 5 by this is usually about 100 to 130 degrees from the state where the upper opening 2a of the seat portion 2 is closed. A permanent magnet 5c is embedded near the step portion 5b around the rotary shaft 5a of the toilet lid 5. Further, when the toilet lid 5 is closed in the upper opening 2a of the seat portion 2, it faces the permanent magnet 5c of the toilet lid 5,
The reed switch 6, which is the closest position, is embedded in the seat 2 side. The reed switch 6 paired with the permanent magnet 5c detects opening / closing of the toilet lid 5, and the reed switch 6 is the toilet lid switch of the present embodiment.

Similarly, it is also possible to configure as shown in FIG. In particular, only the differences will be described. The step portion 5b rotates the hollow portion 2b of the toilet lid 5, and the rotation causes the step portion 5b to come into contact with the stopper portion 2c of the seat portion 2 to regulate the rotation of the toilet lid 5. . For the rotation of the toilet lid 5, a limit switch 7b is arranged near the step portion 5b around the rotating shaft 5a of the toilet lid 5, and when the toilet lid 5 is opened, the rotor 7a of the operating rod is stepped. It is arranged so as to be in rotational contact with a portion counterclockwise of the portion 5b. When the toilet lid 5 is closed in the upper opening 2a of the seat portion 2, the stepped portion 5b of the toilet lid 5 presses the rotor 7a of the operating rod, and the rotation of the toilet lid 5 causes the rotor of the operating rod to rotate. The pressure of 7a is gradually released,
Accordingly, the micro switch 7b detects opening / closing of the toilet lid 5, and the limit switch 7 including the rotor 7a and the micro switch 7b becomes the toilet lid switch of the present embodiment.

Further, as shown in FIGS. 2 and 3, the seat portion 2
The upper opening 2a is formed in a size that allows urination and defecation with the buttocks resting. In addition, the weight of the human body is dispersed around it and is added to the base 3.
The lower surface around the seat portion 2 is recessed downward so that the odor is trapped on the lower surface side of the seat portion 2.

An armrest 3a is formed integrally with the base 3 of the main body 1. This armrest 3a can be used as a support for the body and also as a guide for the buttocks. Further, it also has a function of guiding the seat portion 2 so that it can be placed at a fixed position on the upper surface of the base portion 3. That is, when the seat portion 2 is placed on the upper surface of the base portion 3, the positions of both sides and the rear portion are determined according to the armrest portion 3 a, and the seat portion 2 is moved to the upper surface of the base portion 3 to move the seat portion 2 to the upper surface of the base portion 3. Can be placed in place.

The main body 1 forming substantially the whole of the portable toilet of the present embodiment is a seat portion 2 having an upper opening 2a, and a base portion 3 having an armrest portion 3a which serves as a base of the whole.
And a toilet lid 5 that opens and closes the upper opening 2a of the seat 2. However, the main body 1 for carrying out the present invention is
The seat portion 2 and the base portion 3 can be integrated.

Then, as shown in FIG. 2, a processing container 4 which can be freely inserted into and removed from the front opening 3b of the base 3 of the main body 1.
Has an opening wider than the upper opening 2a of the seat 2. The processing container 4 is basically a substantially rectangular parallelepiped box-shaped container having an upper opening, and has a handle portion 41 on the front surface thereof, which can be inserted and removed and carried. At the center of the processing container 4, an agitator 42, which is supported by bearings on both sides, is arranged. The stirrer 42 obtains a rotational force from a gear 43 attached to a shaft 42a protruding rearward of the processing container 4.
The stirrer 42 has two stirring elements 42b having a spiral shape and a stirring element 42c having a spiral shape opposite to that of the stirring element 42b. The stirring element 42b and the stirring element 42c are 2 at the center.
It is divided. The rotation of the shaft 42a causes the stirring elements 42b and 42c to rotate within the processing container 4, and the stirring elements 42b and 42c perform an operation of collecting in the central direction or dispersing from the center to both sides. The stirring elements 42b and 42c of the present embodiment are spirally connected in parallel to the shaft 42a, and are connected in an arrangement in which the shaft 42a has a uniform balance with respect to 360-degree rotation. Further, the shaft 42a is arranged so that a uniform load is applied to the rotation of the shaft 42a. Therefore, in the processing container 4, the shaft 42 a is rotated by the rotational force applied to the gear 43, and the pair of stirring elements 42
b and the stirring element 42c rotate. This rotation has a small contact resistance due to the bearing, and can be easily rotated.

The rear portion of the processing container 4 is lower than the front surface having the handle portion 41, and is a part of an exhaust path described later. Further, the main body 1 of the present embodiment is separated into the seat portion 2 and the base portion 3, but it is also possible to make the processing container 4 which can be inserted into and removed from the main body 1 in which both are integrated.

A thin metal plate 31 is laid under the front opening 3b of the base 3 into which the processing container 4 is inserted and removed. Although the upper surface of the metal thin plate 31 is substantially smooth, a heater 32 including a thermistor is arranged on the lower surface thereof. A heat insulating material 33 made of a foamable synthetic resin is filled between the lower surface of the metal thin plate 31 and the bottom surface of the base 3. Therefore, the amount of heat generated by the heater 32 is efficiently transferred to the processing container 4 side. The heater 32 is mounted in the main body 1 and constitutes a heating means for controlling the temperature of the processing container 4 mounted in the main body 1 within a predetermined temperature range. Since the heater 32 in the present embodiment is composed of a thermistor, the temperature control is performed by the heater itself, but the on / off control of the energizing current may be performed by temperature detection. Alternatively, the energization current value may be controlled. In this embodiment, the temperature is detected by a temperature sensor (not shown), and the heater 32 including a thermistor is used.
Then, the temperature is further controlled.

A controller 34 is provided on the opposite side of the front opening 3b of the base 3 into which the processing container 4 is inserted and removed. The controller 34 performs electrical control of the entire portable toilet of this embodiment.

FIG. 4 is a block diagram of a controller for controlling the portable toilet according to the first embodiment of the present invention.

The controller 34 comprises a microcomputer 50, and a signal of a temperature sensor for controlling the temperature of the processing container 4 within a predetermined temperature range is input to the input of the microcomputer 50 via a publicly known input circuit (not shown). . Further, the signal of the toilet lid switch including the reed switch 6 or the limit switch 7 is input.

At the output of the microcomputer 50, an ON / OFF signal for the heater 32, which is a thermistor, is output through a publicly known output circuit and driver circuit (not shown). Similarly, the motor forward rotation output that drives the motor 35 in the forward direction and the motor reverse rotation output that drives the motor 35 in the reverse direction are output. Similarly, the exhaust fan strong output and the exhaust fan weak output of the exhaust fan 37 that rotates the exhaust fan 37 in a specific direction with high (high speed rotation) and weak (low speed rotation) are output.

The electric motor 35, which is controlled to rotate at a constant speed by the controller 34, applies a rotational force to the gear 43 of the processing container 4 by the output gear 36 after the predetermined deceleration. That is, when the processing container 4 is mounted on the main body 1, the mounting causes mechanical coupling between the output gear 36 and the gear 43 to impart a rotational force to the agitator 42.

Similarly, the exhaust fan 37 whose rotation is controlled by the controller 34 exhausts the air in the processing container 4 through the catalyst deodorizer 38 and the exhaust port 39 of the base 3. That is, the exhaust fan 37 forcibly exhausts the air in the main body 1 from the exhaust port 39 of the base 3 through the catalyst deodorizer 38.

Next, the general operation of the portable toilet of this embodiment having the above-described structure will be described.

First, the crushed rice husks, wood chips, etc. and aerobic high-temperature fermenting bacteria are mixed and put in the processing container 4 to a height of 50 to 60%. In the present embodiment, crushed rice husks, a mixture of wood chips, etc. and aerobic fermentative bacteria were put, but in the case of carrying out the present invention, a fine powder of a plant constituent containing activated carbon and aerobic fermentative bacteria are used. I wish I had it. The aerobic fermenting bacteria used in the present embodiment used were aerobic high-temperature fermenting bacteria.
However, when carrying out the present invention, it is not limited to aerobic thermophilic fermentative bacteria, fermentative bacteria existing in nature (rice husk, when attached to wood chips, etc., and also those floating in the air (Including) aerobic fermentative bacteria.

Since the temperature at which the aerobic high-temperature fermenting bacterium used in the present embodiment can satisfactorily operate is in the range of 45 to 65 ° C., the treatment container 4 is heated by the heater 32 as a heating means.
The temperature inside is within the temperature range of 50 to 60 ° C., and under the adjusted temperature conditions, once every 8 hours, the crushed rice husks, wood chips, and excrement in the processing container 4 by the agitator 4 are used. Etc. and aerobic fermentative bacteria are mixed and stirred.

Further, at a predetermined time interval, the exhaust fan 37
The air inside the main body 1 to drive the catalyst deodorizer 3
The exhaust fan 37 forcibly exhausts the exhaust air from the exhaust port 39 of the base portion 3 via 8. Note that the exhaust fan 37 is always driven in a weak state by supplying oxygen and removing water to the aerobic fermentative bacteria during the decomposition process of the exhaust, and the temperature of the seat 2 is the temperature inside the processing container 4. This is because it is difficult to be affected by the range of 50 to 60 ° C. and the inside of the main body 1 is set to an atmosphere of about 35 to 40 ° C. The exhaust fan 37 of the present embodiment also functions as an air supply unit that introduces outside air into the processing container 4 mounted on the main body 1.

In this state, when the user sits down on the seat 2 of the main body 1 and excretes from the upper opening 2a of the seat 2, the excrement is agitated under the temperature condition of the temperature range of 50 to 60 ° C. in the processing container 4.
The rice husks, wood chips, excrement, etc. are mixed with the aerobic fermentation bacteria and stirred. When the excrement is mixed and stirred by the agitator 42 with rice husks, wood chips, excrements, etc. and aerobic fermentation bacteria, microorganisms and aerobic fermentative bacteria are produced by the aerobic high-temperature fermenting bacteria in which the rice husks, wood chips, excrements, etc. are actively active. Is fermented and decomposed, and the crushed rice husks, wood chips, and excrement in the processing container 4 become compost.
The compost is a mixture of crushed rice husks, wood chips, etc. and aerobic high-temperature fermentative bacteria with excrement, which is then referred to as "compost".

Fermentative decomposition of excrement by aerobic fermenting bacteria during this period also kills Escherichia coli and other parasite eggs that are harmful to humans at high temperatures. In addition, rice husks in the processing container 4, wood chips,
Even if excrement or the like is used as a fertilizer, no odor is generated and bacteria are not propagated.

When the compost in the processing container 4 is applied as fertilizer or is discarded, the processing container 4 is pulled out from the main body 1. At this time, the mechanical connection between the output gear 36 and the gear 43 is released by the mounting. When mounting the processing container 4 on the main body 1 again, the processing container 4 is fitted into the main body 1. By the insertion, the output gear 36 and the gear 43 are mechanically coupled.

Next, the operation of the portable toilet of this embodiment having the above-described structure will be described with reference to FIGS. 5 and 6.

FIG. 5 is a flow chart for controlling the main program of the portable toilet of the first embodiment of the present invention, and FIG. 6 is a subroutine call in the main program control of the portable toilet of the first embodiment of the present invention. 4 is a flowchart of a motor driving routine performed.

This program is executed by turning on the power (or inserting an outlet). First, when the power is turned on, initialization is performed in step S1, a predetermined timer T and an 8-hour timer are reset, and then step S2 is performed.
Then, the exhaust fan 37 is rotated in a weak state, and step S3
To determine the lapse of 8 hours. When it is determined in step S3 that 8 hours have not elapsed, in step S4 the toilet lid 5
When the toilet lid 5 is not opened, the routine from step S2 to step S4 is repeatedly executed.
In addition, the lapse of 8 hours determined in step S3 is as follows.
It is determined by the characteristics of the main body 1, and usually 5 to 12
It may be set within the range of time, and depending on the conditions, it may be set to drive about 1 to 3 times at night when human activities stop.

When it is determined in step S3 that 8 hours have passed, the timer T is set to t minutes in step S5. The time t set in the timer T is about 1 minute in the present embodiment, and is set as the time required for one rotation operation of the agitator 42. After the electric motor drive routine is called in step S6 and executed, it is determined in step S7 whether the flag F2 is set to "0", assuming that the electric motor drive routine is executed without interruption. When the processing is ended without interruption, the flag F2 is "0",
The routine from step S2 is repeatedly executed.

When the electric motor driving routine is interrupted by opening the toilet lid 5, or from step S2 to step S
When the routine of No. 4 is released by opening the toilet lid 5, the exhaust fan 37 is strengthened in step S8 to increase the exhaust capacity of the exhaust fan 37. As a result, forced exhaust is performed from the exhaust port 39 of the base 3 so that the odor does not flow to the user side.
In step S9, the toilet lid 5 is closed and the routine processing from step S2 is performed again. However, if the opening of the toilet lid 5 continues, it is determined in step S10 whether the opening of the toilet lid 5 has continued for 30 seconds, and the routine from step S8 to step S10 is performed until the opening of the toilet lid 5 continues for 30 seconds. Execute repeatedly. That is, the exhaust capacity of the exhaust fan 37 is increased, and forced exhaust from the exhaust port 39 of the base 3 is continued so that odor does not flow from the upper opening 2a of the seat 2 to the user.

If it is determined in step S10 that the opening of the toilet lid 5 has continued for 30 seconds, it is highly likely that excretion has been performed during that time. Therefore, it is determined in step S11 whether the flag F1 is "1". . "1" of the flag F1 is for determining whether or not the routine after this step S11 is entered for the first time, and flag F1 = "0" is for this step S11.
Indicates that the routine after 11 was entered for the first time.

When the flag F1 is not "1" in step S11, it means that the routine after this step S11 is entered for the first time, and therefore the timer T is set to t / 2 minutes in step S12. T / 2 minutes set in timer T is
In this embodiment, it takes about 1/2 minute, and
The time required for the operation of 1/2 rotation is set. This rotation, or time, is the time to wrap the excrement with fine powder of plant constituents and aerobic fermentative bacteria. After calling the electric motor drive routine in step S13 and executing it, step S1
In step 4, the flag F1 is set to "1". Then, step S1
In step 5, it is determined whether the toilet lid 5 is closed, and in step S15, the toilet lid 5 is closed.
If is not closed, the routine returns from step S8. That is, until the toilet lid 5 is closed, the exhaust fan 37 is kept strong and the exhaust capacity of the exhaust fan 37 is kept large, and when the routine after step S11 is entered again, the flag F1 = "" in step S11. Since it is 1 ", the processes of steps S12 to S14 are omitted, and the step waits for the toilet lid 5 to close in step S15.

If it is determined in step S15 that the toilet lid 5 has been closed, this means that the excretion has ended. Therefore, in step S16, the timer T is set to t minutes. In the present embodiment, t minutes set in the timer T is about 1 minute, and 1 minute of the agitator 42 is used.
It is set as the time required for the rotation operation. In step S17, the excrement is not wrapped with the fine powder of the plant constituent and the powder of the aerobic fermenting bacteria, and there is a possibility that the odor exceeding the capacity of the deodorizer 38 is temporarily scattered. , The exhaust fan 37 is stopped, and the electric motor drive routine is called in step S18 and executed, and then step S
At 19, the progress of 3 minutes is judged. Then, step S1
After waiting 3 minutes at 9, the flag F1 and the flag F2 are set to "0" at step S20, and the routine from step S2 is repeatedly executed.

When the above-mentioned electric motor drive routine is called, the subroutine program shown in FIG. 6 is executed.

First, in step S31, the electric motor 35 is rotated forward, and if the toilet lid 5 is not opened in step S32,
In step S33, it is determined whether the time set in the timer T has elapsed, and the routine of steps S31 to S33 is repeatedly executed until the time set in the timer T has elapsed in step S33. When the elapse of the time set in the timer T is determined in step S33, the motor 3 is determined in step S34.
5 is rotated in the reverse direction, and if the toilet lid 5 is not opened in step S35, it is determined whether or not the time set in the timer T has elapsed in step S36, and the time set in the timer T in step S36 elapses until step S34. The routine from step S36 is repeatedly executed. In step S36, timer T
When the elapse of the time set to is determined, this means that the electric motor drive routine is not interrupted by opening the toilet lid 5, so "0" is set to the flag F2. When it is determined in step S32 or step S35 that the toilet lid 5 has been opened, this means that this electric motor drive routine has been interrupted by opening the toilet lid 5 in step S38, so "1" is set in the flag F2. Then, in step S39, the electric motor 35 is immediately stopped. The stop of the electric motor 35 in step S39 can ensure the safety when the toilet lid 5 is opened.

As described above, the portable toilet of the present embodiment has the upper opening 2a on which the buttocks are placed, and the main body 1 and the main body having the processing container 4 for storing the fine powder of the plant constituent and the aerobic fermentative bacteria. Toilet lid 5 for opening and closing the upper opening 2a of 1
And a stirrer 42 that stirs the fine powder of the plant constituents and aerobic fermentative bacteria in the processing container 4 of the main body 1, an electric motor 35 that drives the stirrer 42, and the air inside the main body 1 is discharged to the outside of the main body 1. The controller 34 includes an exhaust fan 37, and the controller 34 performs steps S31 to S36 of the electric motor drive routine.
When the toilet lid 5 that opens and closes the upper opening 2a is opened during the process (1), the electric motor 35 that drives the agitator 42 is stopped. Therefore, when the toilet lid 5 that opens and closes the upper opening 2a is opened during the stirring operation with the power turned on,
The electric motor 35 that drives the stirrer 42 can be stopped, and even if there is a person who does not have a proper judgment ability or a person who accidentally put his / her hand through the upper opening 2a of the main body 1, those persons are injured. Never. Of course, since the number of rotations is about one rotation per minute, it is possible to eliminate any trouble in the main body 1 in combination with the possibility that harm is not caused even under normal circumstances.

Further, the controller 34 has an upper opening 2a.
When the toilet lid 5 for opening and closing is closed after a predetermined time has passed, it is determined in steps S4 and S6 of the electric motor drive routine and steps S8 to S15, and in steps S8 to S20, the agitator is closed. Since the electric motor 35 that drives 42 is driven for a predetermined time, it is possible to perform the processing after excreting the excrement in accordance with the excretion action of a person only by opening and closing the toilet lid 5, and in particular, immediately after excretion and in the past. In order to block the odor emitted from the excreted waste, it can be wrapped with fine powder of plant constituents and powder of aerobic fermentative bacteria, etc., and does not emit odor.

Then, the controller 34 uses the upper opening 2
Since the electric motor 35 that drives the agitator 42 is driven for a predetermined time when the state in which the toilet lid 5 that opens and closes a is opened continues for a predetermined time, in particular, the odor emitted from excrement during excretion is blocked. Therefore, it can be wrapped with fine powder of plant constituents and powder of aerobic fermentative bacteria, etc., and odor does not leak to the user of the portable toilet from the upper opening 2a.

Further, the controller 34 has an upper opening 2a.
Since the exhaust fan 37 has its exhaust capability improved more than usual from the time of opening the toilet lid 5 for opening and closing until the toilet lid 5 is closed, the odor emitted from excrement during excretion is blocked. Since the air is taken in through the upper opening 2a, the odor does not leak from the upper opening 2a to the user of the portable toilet.

Furthermore, when the controller 34 opens the toilet lid 5 for opening and closing the upper opening 2a and then closes it after a predetermined time, it closes it by the electric motor routine of steps S4 and S6 and steps S8 to S15.

In particular, if human waste is applied to the connection between the switch and the lead wire, the lead wire and the connection may corrode, but the operation reliability can be improved.
It also looks good and is easy to clean.

According to a seventh aspect of the present invention, in the portable toilet according to any one of the first to sixth aspects, the toilet lid that opens and closes the upper opening of the main body is opened below the permanent magnet by the blow molding. In addition to the effect according to any one of claims 1 to 6, since the permanent magnet is fixed to the magnet fitting concave portion, the magnet fitting concave portion including the mounting space is formed. Since the toilet lid is formed by blow molding, any shape can be easily formed. Also, a permanent magnet can be placed in the magnet fitting recess, and even if there is a gap around the permanent magnet, the magnet fitting recess is open downwards, so water droplets may enter or accumulate in it. There is nothing to do. At the same time, the appearance of the surface and the ease of cleaning are improved.
