DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing apparatus for efficiently decomposing garbage generated in a kitchen of a general household by utilizing aerobic bacteria.

[0002]

2. Description of the Related Art Techniques for decomposing kitchen garbage (hereinafter also referred to as “garbage”) using aerobic bacteria and reducing the amount of the garbage include, for example, a technique of detecting the temperature of a culture substrate and controlling the heating (particularly). JP-A-6-190353, JP-A-6-142
634), and a method for determining the life span of bacteria by a temporal change in the temperature of a culture substrate (Japanese Patent Laid-Open No. 8-112).
No. 8), detecting the water content of the culture substrate and controlling the water content according to the water value (Japanese Patent Application Laid-Open No. 7-251146), and energizing time to the heating means according to the load of the stirring means. There are various types such as a control device (JP-A-7-265843), a device that determines that the water retention amount has increased according to the load of the stirring means, and repeats heating and stirring (JP-A-7-265843). Various types are known.

[0003]

However, in each of the above-mentioned known examples, the heating control is performed based on a preset threshold value, or the minimum temperature when starting the stirring of the culture substrate and when stopping the stirring. Temperature gradient from the maximum temperature of the culture, the temperature rise gradient when the stirring member is stirring the culture substrate, or the temperature gradient that decreases when the stirring member stops stirring the culture substrate. It is configured to determine the life. In any case, the heating control is performed based on a predetermined temperature or by detecting a temperature change, the stirring control or the heating control is performed based on a predetermined moisture content, or the life of the culture substrate is determined. doing.

That is, the control is performed based on a preset threshold value, a difference between the minimum temperature and the maximum temperature, and so on.
Control was performed by detecting the activity state of the bacteria pointwise. There is also a method that detects a temporal change in the temperature of the culture substrate, but this is used only as a parameter for determining the life of bacteria, and based on this temporal change, temperature control and moisture content control are performed. Was not considered to do.

[0005] When the control is performed by detecting the environmental state in a point manner, the tendency of the activity state of the bacteria cannot be grasped at all, so that the follow-up control is inevitably performed. In this way, when the follow-up control is performed, it takes time until the bacterial fermentation / decomposition activity starts even if the predetermined control is performed, and it is not possible to efficiently promote the bacterial fermentation / decomposition activity. The result was.

Further, in the above-mentioned conventional example, the temperature is controlled by detecting the temperature, or the temperature and / or the stirring is controlled by detecting the moisture content. In consideration of this, the environment for promoting the breeding activity of bacteria in the garbage disposal tank is not controlled, so that an environment that promotes the fermentative decomposition activity of bacteria could not be created immediately.

[0007] The present invention has been made in view of such a situation of the prior art, and a first object of the present invention is to determine the activity of fermentative decomposition of bacteria by the pattern of temperature change using time from the input of garbage as a parameter. It is an object of the present invention to provide a garbage disposal apparatus capable of grasping a trend and controlling the temperature before the fermentation decomposition activity of bacteria becomes inactive to efficiently decompose garbage.

A second object of the present invention is to provide a garbage disposal apparatus capable of exhibiting an optimum environment in which the fermentation and decomposition of bacteria is actively performed in consideration of the temperature and the moisture content.

[0009]

Means for Solving the Problems In order to achieve the above object, a first means comprises, for example, a stirring blade and a ventilation device for mixing a culture substrate containing at least one of sawdust and rice husk with aerobic bacteria. Put in the garbage disposal tank,

I have.

[0010] In this case, the control may be performed by using a temperature difference change pattern corresponding to a preset time lapse instead of the temperature change pattern corresponding to the preset time lapse.

Preferably, the heating means comprises a main heater and an auxiliary heater comprising a planar cord heater attached to an outer peripheral surface of the garbage disposal tank, and the control means comprises the main heater and / or the auxiliary heater. The operating state of one or both of the auxiliary heaters may be controlled to obtain a desired heating state.

Further, when it is determined that the fermentation / decomposition activity of the aerobic bacteria is in a low state based on the temperature measured by the temperature measuring means, a means for alerting the user of the environmental condition is further provided. Deterioration can also be reported.

[0013] The second means is a kitchen waste treatment apparatus based on the same premise as the first means, wherein a temperature measuring means for measuring the temperature of the culture substrate in the treatment tank; Moisture content measuring means for measuring the moisture content, heating means for heating the inside of the garbage treatment tank, the culture substrate temperature measured by the temperature measuring means and the culture substrate measured by the moisture content measuring means And a control unit for controlling a heating state by the heating unit and a stirring state by the stirring device from the moisture content, wherein the control unit controls the fermentation decomposition activity of the aerobic bacteria to be active. It is characterized by.

[0014] In this case, the control means sets at least three states, that is, a low temperature state, a normal state, and a high state of the culture substrate as the heating state, and sets the water content of the culture substrate as the stirring state. At least three states, a low state, a normal state and a high state, are set such that the lower the temperature of the culture substrate, the longer the heating time of the heating means, and the higher the moisture content of the culture substrate, the longer the stirring time. The heating state and the stirring state may be controlled based on the fuzzy theory according to these states.

A garbage inlet 16 communicating with the upper part of the
The inlet 16 is doubly covered by the outer lid 7 and the outer lid 18. In addition, in order to secure the degree of sealing of the lid, the inner lid 17 and the outer lid 18 are provided with packings for sealing between respective receiving surfaces. Further, a control device 7 for performing various operation controls is provided in a portion corresponding to the back surface of the insertion port 16.

At the bottom of the processing tank 3, an outlet 19 for taking out the contents is provided. The discharge port 19 is normally shielded by a drawer-type shutter 21 having a handle 20. When the user puts his hand on the handle 20 and pulls out the shutter 21, the contents of the processing tank 3 are discharged from the discharge port 19 to the discharge path 22. Since it falls, it can be taken out of the housing 2 by scraping it out.

A culture substrate 23 is contained in the processing tank 3. The culture substrate 23 is mainly composed of a material having poor biodegradability such as lignin, cellulose and hemicellulose. Specifically, sawdust, rice husk, rice straw and the like are cut and used. This culture substrate is such that each grain is porous and has voids, and the grain shape is complicated, uneven, and large voids are formed between the grains.

A door switch 77 (see FIG. 5) is interlocked with the outer lid 18. When the outer lid 18 is opened at a predetermined angle,
When the door switch 77 is opened and the control device 7 turns off the power of the motor 5 in accordance with the door switch 77, the stirring blade 4 is stopped.

The treatment tub 3 is formed of a polypropylene resin widely used for a washing tub of a washing machine and the like, and the sheet heaters 6 and 6a are adhered to the outer peripheral surface thereof over a wide area. The heat insulating foam sheets 24, 24a
Covered by. As shown in FIG. 4, the planar cord heaters 6 and 6a are heating wires 25 wound in a thin coil shape.
Is helically wound around the outer periphery of a cord of a Tetron with a cord 26 as a core, and the cord is coated with an insulating film 27 and the cord is adhered so as to be laid on an aluminum sheet 28. The surface code heaters 6 and 6a monitor the heat generation temperature by a thermistor (not shown) so that the heat generation temperature can be maintained at a predetermined value by a temperature control device incorporated in the control device 7. Has become.

The culture substrate 23 made of sawdust or the like having poor heat conductivity is contained in the processing tank 3. The sheet cord heaters 6 and 6 a are attached to the outer peripheral surface of the processing tank 3 over a wide area. Can be heated more uniformly. Reference numeral 29a is a temperature sensor for measuring the temperature of the culture substrate 23 in the processing tank 3.

The electric components such as the planar cord heaters 6 and 6a, the motor 10 and the motor for driving the fan 15 are as follows.
As will be described later, on / off operation timing, operation continuation time, and the like are controlled by a microcomputer in the control device 7. The planar code heaters 6 and 6a are simultaneously turned on and off in order to keep the entire processing tank 3 warm, and the case where the main heater 6 and the auxiliary heater 6a are used to control the on and off independently. There are times when you do.

In the garbage processing apparatus 1 configured as described above, the moisture content of the base material 23 in the processing tank 3 is reduced to 40 to 60%.
The aerobic bacteria are charged and agitated to create a hotbed for aerobic bacteria to propagate. Then, it is only necessary to open and close the lid every day and to put garbage into the processing tank 3. In the processing tank 3, the control device 7 automatically repeats the stirring and the ventilation automatically at predetermined time intervals. Thereby, the garbage is crushed by being stirred with the base material 23, and is rubbed and worn by the jagged grains of the base material 23,
Aerobic bacteria adhere to the surface, and the aerobic bacteria feed on garbage and reproduce. The garbage is fermented and decomposed into pieces, and most of the garbage is released as steam and carbon dioxide. In addition, low-molecular-weight decomposition products that become plant nutrients as solids, that is, compost, are left in the culture substrate 23. A small amount of gases such as ammonia and trimethylamine, which cause odor, are also included in the generated gas. These water vapor, carbon dioxide gas and other gases are discharged from the processing tank 3 to the outside of the apparatus by the fan 15 at the stage of ventilation, and this operation is intermittently continued by automatic operation.

Although the processing of such garbage may take some time depending on the conditions of use, if it lasts three to six months,
Decomposition products of garbage accumulate, or fermentation substrate 23
The fermentation base material 23 becomes viscous and sticky and juicy due to deterioration of air permeability and increase in moisture content due to abrasion and water absorption of the fermentation material. In such a state, it is not suitable for the propagation of aerobic bacteria, and the fermentation decomposition activity is low, and the temperature of the fermentation base material 23 decreases. And
The function of the anaerobic bacteria gradually increases in the fermentation base material 23, and a rotten smell appears. Therefore, by measuring the temperature of the fermentation substrate 23, it is possible to detect whether the substrate 23 is currently in a state suitable for bacterial propagation and fermentation decomposition activity.

Therefore, the temperature of the culture substrate 23 is monitored by the temperature sensor 29, and when the temperature reaches a preset threshold, the heaters 6 and 6a are energized, and further turned on and off to control the temperature in the processing tank 3. The substrate temperature may be set to a temperature optimal for the fermentation decomposition activity. However, in this method, the control state differs depending on the set threshold value. Therefore, in the present embodiment, a temperature change pattern is stored in advance in which a lapse of time since the garbage was put is used as a parameter, and when the temperature change pattern deviates from this pattern or deviates from the pattern by a predetermined width or more. The heater 6 and / or 6a is energized so that the temperature change matches the temperature change pattern.

FIG. 5 shows a circuit configuration of the control device 7 for performing such control. The control device 7 includes a CPU 70 and a C
ROM 7 connected to PU 70 via bus 80
1, basically comprises a RAM 72, a ROM table 73, a main switch 74, an alarm device 75, temperature sensors 29a and 29b, heaters 6 and 6a, a moisture content sensor 76, a door switch 77, and a motor driver 78.
In the figure, an operation display device 79 for displaying various messages is provided, and a temperature sensor 29a for measuring the temperature in the processing tank 3 and an external temperature sensor 29b for measuring the external temperature are provided as temperature sensors. It is an example.

The CPU 70 controls the entire control device. The ROM 71 stores static information such as a program of the CPU 70, and the RAM 72 stores the static information.
And dynamic information such as data to be processed by the CPU 70 is stored. The ROM table 73 stores a reference pattern such as a temperature change pattern using time as a parameter in the form of a table. Note that a plurality of such patterns are prepared according to the outside air temperature, the amount of the culture substrate 23, and the like.

The main switch 74 is provided on the housing 2.
By performing the ON operation, the kitchen waste disposal apparatus 1 starts operating. When the CPU 70 determines that the state of the culture substrate 23 has become unsuitable for bacterial fermentation decomposition activity based on the measurement results of the in-chamber temperature sensor 29a and the moisture content sensor 76 described below, This is for notifying by a lamp, and when the operation display device 79 is attached, it is also possible to configure so that in addition to the notification, the content of the alarm is displayed by a message.

The in-bath temperature sensor 29a is provided on the inner surface of the processing bath 3 as described above, and measures the temperature of the culture substrate 23. The outside air temperature sensor 29b is provided on the outer surface of the housing 2, and measures the outside air temperature. Measure. As the moisture content sensor 76, an electric conductivity sensor for obtaining the moisture content of the culture substrate 23 from a change in the electric conductivity of the culture substrate 23 is used here.

The moisture content is determined by the culture substrate 23
It can be indirectly measured by replacing it with a physical quantity that changes in response to the change in the moisture content and is easy to sense. Therefore, instead of the electric conductivity sensor, for example,
Change in rotational torque required to stir the culture substrate 23,
The current value and the number of rotations of the motor 10 for driving the stirring blade, which change according to the change of the rotation torque,
A change in the waveform of the terminal voltage of the phase-advancing capacitor, which occurs when the power supply is turned off, and the pH (pH) of the culture substrate 23 itself can be used. Of course, an infrared moisture measurement sensor that utilizes the fact that the amount of absorption changes due to the amount of moisture during infrared irradiation can also be used.

More specifically, since a change in the rotation torque of the rotating shaft 5 causes a change in the number of rotations of the motor 10 for driving the rotating shaft 5, a permanent magnet is fixed to the rotating shaft of the motor 10,
The moisture content can be measured by an encoder-type rotation speed sensor that captures this change in rotation speed using a Hall element. This rotation speed sensor is useful because it can also be used as a lock sensor for detecting an unrotatable state. In addition, when an induction motor using a phase-advancing capacitor is used as the motor 10 when the motor 10 is turned off, the back electromotive force generated at the terminal of the phase-advancing capacitor can be changed by changing the torque required to turn the rotary blade 4. It can be known from the voltage decay characteristics, for example, the decay time of the back electromotive voltage or the number of peaks of the voltage waveform until the back electromotive voltage disappears. In addition, although these specific structures are not particularly shown, they can be measured using a conventionally known general-purpose electronic circuit technology.

The door switch 77 outputs an opening signal to the CPU 70 when the outer cover 18 is opened at a predetermined angle. When this signal is input, the CPU 70
Is notified to the motor driver 78 which controls the driving of the motor 10, and when the motor 10 is rotating, the motor 10 is stopped.

The operation display device 79 is composed of, for example, a touch panel, and selects a mode such as inputting the amount of garbage by key input, processing based on the above-described temperature pattern, or processing considering the temperature and moisture content described below. As the display, the contents of the alarm when the alarm is issued as described above, the prompting of the input of kitchen waste when the amount of kitchen waste to be processed is reduced in quantity, Or the life of the device can be notified by a display.

The indication of the life of the culture substrate 23 is, in particular,
It is effective when the moisture content decreases. That is, when the input amount of garbage is small in a small family, or when idling is continued without inputting garbage on a trip or the like, the culture substrate 23
Moisture content decreases and dries dry. This makes it difficult for bacteria to multiply, and the spores can be sporulated or killed. In such a state, the garbage is no longer decomposed by bacteria, the garbage disposal apparatus 1 becomes a garbage dryer, and dried garbage accumulates in the treatment tank 3. Then, the culture substrate 23 becomes worn and finely divided, and cannot be reused. At this time, it is necessary to add water to increase the water content, but in the past it often failed due to the user's intuition. If the moisture percentage is also displayed, appropriate water replenishment can be performed without depending on the user's intuition as in the conventional case. It is to be understood that kitchen waste can be processed without the operation display device 79 having such a function.

In this embodiment, two heaters 6 and 6a are provided, one of which is a main heater and the other is an auxiliary heater so as to be suitable for a garbage disposal apparatus for cold regions. When the temperature of the outside air decreases to a predetermined temperature in winter or the like, the main heater 6 is operated to keep the temperature, and the temperature sensor 29a in the bath.
Thus, the temperature of the culture substrate 23 is detected, and the fermentation decomposition activity of bacteria is controlled so as not to deviate from the temperature change pattern. At this time, it is also possible to control the outside air temperature and the temperature of the culture substrate 23 by taking into consideration the outside air temperature and the temperature of the culture substrate 23 by the outside air temperature sensor 29b, and more efficient processing can be performed by such control.

At this time, when the time change pattern of the temperature of the culture substrate is viewed from the time when the garbage is introduced by opening and closing the lids 17 and 18, the temperature change pattern corresponding to the lapse of time set in advance is obtained. When it deviates, it is possible to determine that the fermentation decomposition activity of the bacteria is in a low state, and to operate the warming heaters 6 and 6a for the fermentation decomposition treatment and for promoting the evaporation of water. With this control,
Based on the fact that the temperature change of the culture substrate 23 changes at a constant rhythm during the day, by comparing with the constant rhythm, it is possible to judge the substrate state with higher accuracy, and to further improve the efficiency. Good processing becomes possible.

In this case, instead of observing the temporal change pattern of the temperature of the culture substrate 23, a preset temperature difference change pattern corresponding to the passage of time from the input of the garbage may be observed.

In this embodiment, the temperature control is performed by monitoring the change pattern of the temperature with respect to time or the change pattern of the temperature difference, but the fermentation decomposition state depends on the temperature and the moisture content of the fermentation base material 23 as described above. If both are monitored and the temperature and the moisture content are controlled so that they are in appropriate ranges, kitchen waste can be more efficiently processed. Hereinafter, an example in which kitchen processing is performed using both the temperature and the moisture content as parameters will be described. Note that the kitchen waste processing apparatus itself is the same as the kitchen waste processing apparatus 1 in the above-described embodiment with reference to FIGS.

In this embodiment, as described above, garbage processing is performed based on fuzzy inference using both temperature and moisture content as parameters. The moisture content of the culture substrate 23 is detected by the moisture content sensor 76, and The temperature of the substrate 23 is detected by the in-chamber temperature sensor 29a, and fuzzy inference is executed by the CPU 70 of FIG. 5 based on these detected values. At that time, control is performed as follows according to the substrate temperature and the moisture content.

[0043]

[Table 1]

That is, the above table shows the inference rules of fuzzy inference. The fuzzy inference rules of the present embodiment are as follows: "When the temperature of the culture substrate is low, the propagation of aerobic bacteria is inactive, When the temperature of the material is high,
Reproduction of aerobic bacteria is active. When the moisture content of the culture substrate is low or high, it is difficult to propagate aerobic bacteria. When the moisture content of the culture substrate is appropriate, the growth of aerobic bacteria is active. "Based on the general recognition of the propagation and decomposition activity of the culture substrate 23. In this inference rule, the qualitative concept of “low”, “normal” and “high” in the moisture content of the base material, and “low”, “normal” and “high” of the base material temperature
The qualitative concept is quantitatively expressed by membership functions, for example, as shown in FIGS. 6A and 6B as an example, and based on these functions, the most optimal bacterial reproduction is performed by known fuzzy theory. The environment in the treatment tank is optimized so as to satisfy the decomposition conditions, in other words, the kitchen waste treatment conditions that can be processed in the shortest time. The membership functions are stored in the ROM 71 in advance, and the CPU 70 performs fuzzy control with reference to the stored membership functions.

Although the temperature and the agitation control are performed by setting the membership function based on the fuzzy inference in this case, even if the fuzzy inference is not used, the water content of the base material and the temperature of the base material may be varied in advance. ROM pattern
It is also possible to store the information in the table 77 and set the temperature and the stirring control based on this pattern so as to provide an optimum environment in which the fermentation decomposition activity is actively performed.

[0046]

According to the present invention, the temporal change pattern of the temperature of the base material measured by the temperature measuring means starting from the time when the garbage is thrown in by opening and closing the lid in the processing tank is set in advance. When the temperature deviates from the temperature change pattern corresponding to the passage of time or when the temperature deviates from the temperature difference change pattern, the heating means is controlled so as to obtain a desired heating state, so that it is possible to immediately respond to actual garbage input. It is possible to prepare an environment for promoting the fermentation decomposition activity, and thereby it is possible to efficiently decompose kitchen garbage.

Further, according to the present invention, it is possible to prepare an optimum promotion environment for the fermentation decomposition activity in consideration of the temperature and the moisture content of the culture substrate in the treatment tank, so that more efficient kitchen garbage decomposition processing can be performed. Becomes possible.
