Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal apparatus suitable for general household or business garbage disposal machines using microorganisms. In detail, air with a bad smell exhausted from the inside of the container for decomposing garbage to the outside of the container is deodorized by the combustion means, and the container and the outside air are warmed by the waste heat of the combustion means, so that at least the exhaust The heat source for deodorization and the heat source for keeping the container warm can be commonly used by one combustion means.

[0002]

2. Description of the Related Art In recent years, a garbage disposal apparatus has been developed which decomposes garbage discharged from kitchens, kitchens and kitchens of general households, restaurants and hospitals into water and carbon dioxide using aerobic microorganisms. Is being developed. This type of garbage disposal apparatus is provided with a container for accommodating garbage, and a chip member (sawdust) serving as a hotbed of microorganisms is put into the container. When the garbage is thrown into the container, microorganisms obtain oxygen and propagate while the garbage is stirred with the chip member, and the microorganisms decompose the garbage into moisture and carbon dioxide.

[0003] Since the activity (propagation) of microorganisms used in this kind of garbage disposal apparatus becomes slow unless a certain temperature is maintained, an electric heater for maintaining the container at a constant temperature is required. A planar heater of this type is provided around the outer periphery of the container.

On the other hand, most of the garbage, such as vegetables and bread crumbs, targeted by such a garbage disposal apparatus is water. The activity of microorganisms requires a certain amount of water, but the activity (propagation) becomes dull if the water becomes excessive. Therefore, it is necessary to ventilate the inside of the decomposition tank 3 with a fan or the like in order to dry the air in the container.

[0005] As the garbage decomposition process progresses, carbon dioxide and air with a bad smell accumulate in the container. Therefore, ventilation is also required for exhausting and supplementing oxygen. During this ventilation, a deodorizer such as activated carbon is used to remove odors from the air exhausted from the inside of the container to the outside of the container.

[0006] In addition, when cold outside air is suddenly taken into the container during ventilation at this time, dew condensation occurs. The moisture from the dew interferes with the activity of the microorganisms. Therefore, the outside air must be heated in advance by a heating means such as an electric heater.

[0007]

As described above, according to the conventional garbage disposal apparatus, at least a heat source for keeping the temperature in the container at a constant temperature, and a heat source for warming the outside air during ventilation. Three heat sources are required: a heat source for warming and a heat source for deodorizing to remove bad smell during exhaust. In addition, it is necessary to individually supply energy for maintaining each heat source. Therefore, the cost of the garbage processing apparatus is increased due to an increase in the number of components such as a plurality of heat sources and wirings leading to the heat sources.

In view of the above, the present invention has solved such a conventional problem. At least, a heat source for exhaust deodorization and a heat source for keeping the container warm can be commonly used by one combustion means. A garbage disposal device is proposed.

[0009]

In order to solve the above-mentioned problems, a garbage disposal apparatus according to the present invention includes a container for storing garbage and decomposing the garbage, and a blower for ventilating the air in the container. Means, and combustion means for burning air exhausted from the inside of the container to the outside of the container by the air blowing means, wherein the air exhausted from the inside of the container to the outside of the container is deodorized by the combustion means, and the container It is characterized by being made to warm.

According to the present invention, since the air exhausted from the inside of the container to the outside of the container is burned by the combustion means, the air is deodorized, and the container is warmed by waste heat by the combustion means. A heat source for exhaust deodorization and a heat source for keeping the container warm can be commonly used by one combustion means. Therefore, since it is not necessary to separately provide a heat source for exhaust deodorization and a heat source for keeping the container warm, the number of components can be reduced, and the cost of the garbage disposal device can be reduced.

[0011]

Next, an embodiment of the garbage disposal apparatus according to the present invention will be described in detail with reference to the drawings.

(1) First Embodiment FIG. 1 is a perspective view showing a configuration of a garbage disposal apparatus 100 according to a first embodiment of the present invention. In this embodiment,
The air exhausted from inside the container that decomposes garbage to the outside of the container is deodorized by the combustion means, and the waste heat from the combustion means is used to warm the air taken into the container from the outside of the container and the outside of the container. In addition to the above heat source and the heat source for keeping the container warm, a heat source for heating the outside air can be commonly used by one combustion means.

The garbage disposal apparatus 100 according to the present invention decomposes garbage and the like discharged from kitchens of general households, kitchens of hospitals and kitchens of restaurants into water and carbon dioxide.
The garbage disposal apparatus 100 has a rectangular column-shaped cabinet 1 shown in FIG. 1 as a housing. The size of the cabinet 1 is, for example, about 70 to 80 cm in length and 50 to 6 in width in the case of an apparatus for processing garbage having a daily production of about 1 to 2 kg.
It is about 0 cm and the depth is about 45 to 50 cm.

For the cabinet 1, a member having good water resistance, waterproofness and weather resistance is used. In this example, after the iron plate is molded, the iron plate is subjected to enamel processing. The upper part of the cabinet 1 is opened, and this opening 1
A is provided with a lid 2 having good airtightness so that garbage can be taken into the cabinet 1 from the outside.
A lid receiver 1B is provided on the outer periphery of the opening 1A.

In this example, in order to improve the airtightness, a rubber packing (not shown) is attached to the back side of the lid 2 or to the lid receiving portion 1B. This rubber packing is sandwiched between the lid 2 and the lid receiving portion 1B. With such a structure, in addition to airtightness, one air circulation system that circulates air inside the container and one air ventilation system that ventilates air inside the container are used.
The two blowing means can be used in common.

Inside the cabinet 1, there is provided a bottomed decomposing tank 3 as a container, which stores garbage and decomposes the garbage. The decomposition tank 3 is made of stainless steel having corrosion resistance and fire resistance and formed into an inverted kamaboko or hopper shape.

A plurality of chip members 4 are put into the decomposition tank 3 so that microorganisms for decomposing garbage can be propagated. In this example, aerobic microorganisms are used to decompose garbage. As the microorganism, koji mold, enzymes and the like are used.

Further, a stirring member 5 having a plow shape is provided in the decomposition tank 3, and the garbage and the chip member 4 are stirred. The stirring member 5 is joined to a shaft portion 6, and both ends of the shaft portion 6 become shafts 7, which are engaged with bearing portions 8 provided on both sides of the decomposition tank 3. One end of the shaft 7 is taken out of the disassembling tank 3, and a pulley (belt wheel) 9 is attached to the shaft 7. The pulley 9 is connected to a motor 11 via a V-belt 10, for example. This motor 1
1, a geared motor is used, and a gear is built in so as to reduce the rotation speed of several thousand rpm to several tens to several hundreds rpm. This is because high-speed rotation is not required for stirring the garbage and the chip member 4.

A combustion device 60 as a combustion means is provided below the above-mentioned decomposition tank 3, and burns air with a bad smell exhausted from the inside of the decomposition tank 3 to the outside of the decomposition tank 3. The air exhausted from the inside of the decomposition tank 3 to the outside of the decomposition tank 3 is deodorized by this combustion, and the decomposition tank 3 is warmed by waste heat from the combustion device 60. Air with foul odor is, for example, 10
It is known that decomposition occurs when heated to about 00 ° C. In this example, the temperature in the decomposition tank 3 is suppressed to about 50 to 60 ° C. For this purpose, an appropriate heat insulating member is inserted between the decomposition tank 3 and the combustion device 60 to reduce the amount of heat transfer, or
Reduce the amount of gas supply to reduce the calorific value.
Ceramic, air or glass wool is used for the heat insulating member.

The combustion device 60 is formed by processing stainless steel or the like having corrosion resistance and fire resistance into a box shape.
In particular, the upper part is curved so as to be along the bottom of the inverted crab-shaped decomposition tank 3. The combustion device 60 is provided with a combustion chamber 62 having a window 61 made of fire-resistant glass. The window 61 is provided so that the internal combustion state can be checked.

The combustion chamber 62 is provided with a gas burner 63 as a combustion tool, so that air exhausted from the inside of the decomposition tank 3 to the outside of the decomposition tank 3 is directly burned and the decomposition tank 3 is directly heated. . Regarding the gas burner 63, it is preferable to use gas for city gas in a city gas supply area or use propane gas in a propane gas supply area. As the burner, an oil burner or an electric heater is used in addition to the gas burner 63.

In this example, a platinum catalyst member may be provided in the combustion chamber 62, and the air exhausted from the inside of the decomposition tank 3 to the outside of the decomposition tank 3 may be deodorized by the catalyst. For example, an opening is formed in a refractory member through which air flows, a platinum wire is applied to the opening, and the platinum wire is red-heated by the gas burner 63. When a gas with a bad smell is passed through the hole whose temperature has been locally increased, the gas can be burned and decomposed even at a low temperature of 300 to 500 ° C.

In this example, the air taken into the decomposition tank 3 from outside the decomposition tank 3 is heated by using the waste heat of the combustion device 60. Thereby, the heat source for exhaust deodorization, the heat source for keeping the decomposition tank warm, and the heat source for heating the outside air are combined into one combustion device 60.
Can be used in common.

A blower 64 is connected to, for example, the right side of the combustion device 60 via a ventilation duct 66.
Air is blown to zero. The reason for attaching the blower 64 is
This is because the air exhausted from the inside of the decomposition tank 3 to the outside of the decomposition tank 3 generally contains a large amount of carbon dioxide and is in an oxygen-deficient state, and complete combustion in the combustion device 60 is not expected only with the air. Therefore, oxygen is supplemented by the blower 64.

An operation panel 12 is provided on the upper right side of the cabinet 1. The operation panel 12 includes a power switch SW, a liquid crystal display 13 for displaying a message such as "combustion operation", an input key 14A for setting "strong / medium / weak" of rotation of the stirring member 5, and a combustion device 60. A start button 14B for starting and an LED 15 for operation display are provided. AC plug 1 at the bottom of operation panel 12
A control board 17 having wirings reaching 6 is provided. A control unit 18 is mounted on the control board 17. This control unit 18 will be described with reference to FIG.

An intake port 19 is provided on the upper right side of the cabinet 1 shown in FIG.
It is heated at 0 and taken into the decomposition tank 3. An exhaust port 21 is provided adjacent to this position, and the exhaust gas 20D after burning air with moisture and odor generated inside the decomposition tank 3
Is exhausted. The intake port 19 and the exhaust port 21 are formed in a lattice shape so that foreign substances do not enter the cabinet 1 from the outside. Legs 1C to 1F on the bottom of cabinet 1
(Only 1C and 1D are shown in the figure).
0 is placed on a veranda in a multi-family house and used outdoors such as a dog running in a detached house.

Further, an environment maintaining unit 22 as an environment maintaining means is connected to the inside of the decomposition tank 3, so that the inside of the decomposition tank 3 is maintained in an optimum operating environment. In this example, the environment maintaining unit 22 is integrated (unitized) in advance and the cabinet 1
And is attached so as to be hooked on the lid receiving portion 1B.

FIG. 2 is a perspective view showing an example of the configuration of the environment maintaining unit 22. The environmental maintenance unit 22 shown in FIG. 2 includes a main body 23, an intake port 24 for circulation ventilation, and an exhaust port 25.
, An intake duct 26 and an exhaust duct 27A. With this structure, it is possible to eliminate the flow of air from other than the intake port 24, the exhaust port 25, the intake duct 26, and the exhaust duct 27A, and to circulate the air in the decomposition tank 3 and the air inside the decomposition tank 3. One ventilation means can be used in common with the air ventilation system that ventilates the air.

The main body 23 has an elongated box shape, and has inverted L-shaped mounting portions 23A and 23B at both ends. By these attaching parts 23A and 23B, it is attached in the disassembling tank 3 of the cabinet 1 so as to be hooked on the lid receiving part 1B. It is preferable that the ceiling portion of the main body 23 be integrated to ensure airtightness.

At the bottom of the left side of the main body 23, there is provided a suction port 24 which is opened, for example, in a circular shape, and the air in the decomposition tank 3 is taken into the main body 23. For example, a circular opening 32A is opened in the side wall, and the opening 32A is formed.
Is connected to the intake duct 26, and warm air from the combustion device 60 is taken into the main body 23. A fan 29 as a blower is provided in the main body 23 adjacent to the intake port 24 to circulate air in the decomposition tank 3 or ventilate the air in the decomposition tank 3. As the fan 29, an axial fan or a sirocco fan is used.

A motor 31 is connected to the fan 29. In this example, the fan 29 is rotated so that air taken in from the intake duct 26 and the intake port 24 always moves toward the exhaust port 25. For example, AC10
AC such as a shade type or capacitor type driven by 0V
A motor is used. Of course, the present invention can also be applied to what is called an inverter motor for DC drive.

On the exhaust side of the fan 29, an exhaust duct 27A, an exhaust port 25 for circulating ventilation, and a valve mechanism 30 for adjusting the amount of ventilation are provided in the main body 23. The exhaust duct 27A is connected to, for example, a circular opening 32B opened on the right rear side wall of the main body 23, and is connected to the combustion device 60 described above. In this example, a valve mechanism 30 is attached near the entrance of the exhaust duct 27A and inside the main body 23, and the amount of air flowing inside and outside the decomposition tank 3 is adjusted. An exhaust port 25 for circulating ventilation is provided at the right bottom portion of the main body 23, and outside air taken in from the intake duct 26 and air circulated in the decomposition tank 3 are exhausted from the main body 23 into the decomposition tank 3.

FIG. 3 is a partial cross-sectional view showing an example of the configuration of the valve mechanism 30 for adjusting the amount of ventilation as viewed from the front, and FIG. 4 is a partial cross-sectional view as viewed from the side. The valve mechanism 30 shown in FIG. 3 includes a shaft 3 on the main body 23 side of the exhaust duct 27A.
For example, a circular-shaped valve body 34 having a 3 is provided. The main body 23 has bearings 35A and 35B at positions adjacent to the opening 32B of the exhaust duct 27A.
The shaft portions 33 of the valve body 34 are engaged with the bearing portions 35A and 35B to form a fulcrum shaft. A solenoid (electromagnet) 36 shown in FIG. 4 is connected to one end of the shaft portion 33 of the valve body 34, and the opening of the valve body 34 is adjusted with reference to the fulcrum axis.

Therefore, the amount of air exhausted to the combustion device 60 (see FIG. 1) through the exhaust duct 27A and the amount of air sent into the decomposition tank 3 from the exhaust port 25 for circulating ventilation are adjusted. Can be. Note that such a valve body 34 is not provided in the intake duct 26. The reason is that there is no circulation of air from outside the decomposition tank 3 into the decomposition tank 3 during circulation, and the same amount of outside air 20 exhausted from the inside of the decomposition tank 3 to outside during ventilation.
This is because a structure that incorporates C is adopted.

Subsequently, the intake duct 26 and the exhaust duct 2
An example of the arrangement of 7A and 27B will be described. FIG. 5 is a sectional view of the cabinet 1 as viewed from the back. The intake duct 26 shown in FIG. 5 is piped into the combustion chamber 62 from the above-described intake port 19, is bent in a U-shape without opening the end portion in the combustion chamber 62, and is again out of the combustion chamber 62. It is pulled out and connected to the environment maintaining unit 22. This is because the purpose is only to warm the outside air 20C.

The exhaust duct 27A is piped from the above-mentioned environment maintaining unit 22 into the combustion chamber 62, and the end of the exhaust duct 27A is opened in the combustion chamber 62. Exhaust duct 27B
Is drawn out of the combustion chamber 62 and connected to the exhaust port 21. The exhaust duct 27A and the exhaust duct 27B are
In the gas burner 63, the air with the bad smell exhausted through the exhaust duct 27A is directly separated.
Because it burns.

Next, the operation of the garbage disposal apparatus 100 during intake and exhaust will be described with reference to FIG. FIG. 6 shows FIG.
1 is a diagram in which the configuration diagram of the garbage disposal apparatus 100 shown in FIG.

In this example, it is assumed that a gas regulating valve 65 is connected to the gas burner 63, the amount of gas supplied to the gas burner 63 is adjusted, and air is sent to the combustion chamber 60 by the blower 64. Of course, the apparatus 100 is operated with the lid 2 completely sealed in the cabinet 1.

For example, in the decomposition tank 3 shown in FIG.
When circulating B, the valve body 34 is completely closed by the solenoid 36 (not shown), and the air 20B is circulated in the decomposition tank 3 by the fan 29. At this time,
Exhaust port 25 of environmental maintenance unit 22 by fan 29
The air 20B that has flowed out is drawn into the intake port 24 of the environment maintaining unit 22 through the inside of the decomposition tank 3, and circulates between the decomposition tank 3 and the environment maintaining unit 22.

Of course, in this case, the opening of the valve body 34 may be adjusted so that air is slightly taken into the decomposition tank 3 from outside the decomposition tank 3. Generally, it is said that the temperature at which the microorganism actively activates is about 25 to 40 ° C., depending on the type of the microorganism. Therefore, the temperature in the decomposition tank 3 is set to 60 ° C. at the maximum.
The gas supply amount of the gas burner 63 is adjusted so as to keep the gas supply amount at a level. As a result, the inside of the decomposition tank 3 can be maintained at a temperature at which microorganisms can easily be activated.

When the decomposition of garbage progresses and moisture (saturated steam) and carbon dioxide increase in the decomposition tank 3, the air in the decomposition tank 3 is ventilated. In this case, for example, the valve body 34 is opened by a half (appropriate amount) by a solenoid 36 (not shown), and the amount of air taken in from the outside of the decomposition tank 3 into the decomposition tank 3 and the amount of air circulating in the decomposition tank 3 are halved. At the same time, the air in the decomposition tank 3 is
Exhaust to zero. Of course, the valve body 34 is opened by 1/3 to reduce the amount of air taken into the decomposition tank 3 from outside the decomposition tank 3 by 1/3.
3, and the opening of the valve body 34 may be adjusted so that the amount of air circulating in the decomposition tank 3 is 2/3.

At this time, the air with a bad smell guided from the environment maintaining unit 22 through the exhaust duct 27A into the combustion chamber 62 is directly burned by the gas burner 63 in the combustion chamber 62. The exhaust gas 20D after combustion is exhausted from the exhaust port 21 through the exhaust duct 27B. Therefore,
The fan 29 and the valve body 34 combine the humid air or the air with the bad smell in the decomposition tank 3 with the dry air (outside air) outside the decomposition tank 3.
The occurrence of dew condensation and oxygen deficiency in the decomposition tank 3 which hinder the activity of microorganisms can be prevented.

In this example, when the outside air 20C is taken into the decomposition tank 3 from the outside of the decomposition tank 3 shown in FIG.
Is forcibly heated in the combustion chamber 62. Therefore, outside air 20
Even when cold air that causes a temperature difference between C and the air 20B in the decomposition tank 3 is rapidly introduced into the cabinet 1, dew condensation can be prevented. For example, if the inside of the decomposition tank 3 is 30
This is a case where the air temperature is kept at about ℃, and air having an outside air temperature of about 5 ℃ is taken therein. Even in such a case, the decomposition tank 3
The moist air inside the decomposition tank 3 and the dry air outside the decomposition tank 3 can be exchanged without obstructing the activity of the microorganisms inside. This can sufficiently contribute to maintaining the air environment of the microorganisms in the decomposition tank 3.

Further, according to this example, since the fan 29 is integrated (unit) inside the environment maintaining unit 22, the fan 29 is not affected by moisture due to condensation as in the conventional system, and the fan 29 and the motor 31 are not affected. Failure can be prevented.

Next, a configuration example of the control unit 18 used in each embodiment will be described. The power switch SW shown in FIG. 7 is connected to the AC plug 16 shown in FIG.
The control unit 18 is connected to the power switch SW.

The control unit 18 is provided with a power supply unit 47, which converts AC 100V into a control DC voltage VCC of, for example, DC 5V. DC voltage VCC from power supply unit 47
Is a microcomputer (hereinafter referred to as a microcomputer) 48,
It is supplied to the motor control unit 49, the combustion control unit 50, the solenoid control unit 53, and the LED 15. A motor control unit 49 is connected to an output stage of the microcomputer 48, and based on the motor control signal S2 from the microcomputer 48, the above-described motor 11 for driving the stirring member is controlled in speed such as “strong / medium / weak”. Is done.

In this example, a temperature sensor 51 is connected to the input stage of the microcomputer 48. The temperature sensor 51 is mounted in the cabinet 1 and detects the temperature of the air in the decomposition tank 3. The temperature detection signal S1 from the temperature sensor 51 is converted into a digital signal and output to the microcomputer 48. Microcomputer 4
At 8, the temperature of the air in the decomposition tank 3 is recognized based on the temperature detection signal S1. In this example, the microcomputer 48 compares the temperature information based on the temperature detection signal S1 with a preset reference value, and activates the combustion control signal S3 based on the result.

A combustion control unit 50 is connected to the output stage of the microcomputer 48, and outputs a combustion control signal S3 from the microcomputer 48.
The combustion control of the combustion device 60 is performed based on. For example, when the temperature in the decomposition tank 3 becomes lower than the reference value, the gas control valve 65 is adjusted to increase the gas supply amount to the gas burner 63. When the temperature in the decomposition tank 3 exceeds the reference value, the gas control valve 65 is adjusted to reduce the amount of gas supplied to the gas burner 63. By this control, the temperature in the decomposition tank 3 is maintained at about 25 to 40 ° C., and the optimum activity environment of the microorganism is maintained.

Further, a solenoid control unit 53 is further connected to the output stage of the microcomputer 48, and the solenoid 36 in the environment maintaining unit 22 is drive-controlled based on the solenoid control signal S4 from the microcomputer 48. At this time, when air is circulated in the decomposition tank 3, the valve body 34 is completely closed by the solenoid 36 shown in FIG. 4, and the air 20 </ b> B is circulated in the decomposition tank 3 by the fan 29.

When ventilating the air 20B in the decomposition tank 3, the solenoid 36 opens the valve body 34 by an appropriate amount to increase the amount of outside air 20C taken into the decomposition tank 3 from outside the decomposition tank 3. The fan 20 exhausts the air 20B in the decomposition tank 3 to the combustion device 60.

Next, the overall operation of the garbage disposal apparatus 100 according to the first embodiment will be described with reference to FIGS. In this example, it is assumed that the microcomputer 48 shown in FIG. 7 executes the circulation mode and the ventilation mode in order to maintain the inside of the decomposition tank 3 at a constant temperature. The circulation mode is an operation of controlling the combustion device 60 based on the temperature detection signal S1 obtained from the temperature sensor 51 shown in FIG. 7 and circulating the air 20B in the decomposition tank 3. The ventilation mode is an operation for ventilating the air 20B in the decomposition tank 3. Of course, it is assumed that the gas burner 63 is connected to the gas pipe 67.

First, the lid 2 of the cabinet 1 shown in FIG.
Is opened, and after confirming that an appropriate amount of the chip member 4 is accommodated in the decomposition tank 3, the garbage 20A is charged. This is because if there is no appropriate amount of the tip member 4, oxygen cannot be sufficiently distributed to the microorganisms. Thereafter, the lid 2 is firmly closed with respect to the cabinet 1. Then, the AC plug 16 shown in FIG. 8 is inserted into an outlet (not shown), and the power switch SW shown in FIG.
While C100V is applied, power is also supplied to the motor 11 for driving the stirring member. Then, the LED 15 is turned on, and the motor 11 rotates. The stirring member 5 is driven by the rotation of the motor 11.

Next, a gas main valve (not shown) is opened to make gas supply to the gas burner 63 possible. afterwards,
Press the input key 14B. The microcomputer 48 receives a combustion operation instruction from the user by this key input, and receives the combustion control unit 5 from the microcomputer 48.
The combustion control signal S3 is output to 0. In the combustion control unit 50, the gas burner 63 is ignited based on the combustion control signal S3. Thereafter, based on the temperature detection signal S1, the microcomputer 4
The combustion control is performed such that the opening degree of the gas control valve 65 is adjusted based on the combustion control signal S3 output from the control unit 8. Of course, there is an optimal temperature (for example,
When the temperature reaches about 30 to 40 ° C.), the supply of gas to the gas burner 53 is cut off by the combustion control unit 50 to which the combustion control signal S3 from the microcomputer 48 has been input.

Immediately after the start of use of the present apparatus 100, a circulation mode is executed to shift the inside of the decomposition tank 3 to a constant temperature. In this circulation mode, the motor 31 (not shown) in the environment maintaining unit 22 is driven, and the fan 29 is rotated.

The microcomputer 48 outputs a solenoid control signal S4 to the solenoid control unit 53.
The drive of the solenoid 36 in the environment maintaining unit 22 described above is controlled based on 4. In this circulation mode, the valve body 34 is completely closed by the solenoid 36, and the air 20B is circulated in the decomposition tank 3 by the fan 29 (see FIG. 6).

In this example, the microcomputer 48 always recognizes the temperature of the air 20B in the decomposition tank 3 based on the temperature detection signal S1 obtained from the temperature sensor 51. Then, when the decomposition process is performed for several hours and the inside of the decomposition tank 3 is executed in the ventilation mode, the combustion control signal S3 is activated. At this time, in the combustion control unit 50, the calorific value is adjusted by increasing or decreasing the above-described gas regulating valve 65, and the outside air 20C taken in from the intake duct 26 is decomposed by the combustion device 60 into the decomposition tank 3.
Heated to the same temperature as inside.

The valve body 3 is controlled by the solenoid 36.
4 is opened by an appropriate amount to increase the amount of outside air 20C taken into the decomposition tank 3 from the outside of the decomposition tank 3, and the air in the decomposition tank 3 is exhausted by the fan 29 to the combustion device 60 and burned. Deodorizes (see FIG. 6). Thereby, the raw garbage 20A is decomposed into water and carbon dioxide in the decomposition tank 3, the decomposed water is dried, and the air with a bad smell is burned and exhausted from the exhaust port 21.

As described above, according to the present embodiment, the air exhausted from the inside of the decomposition tank 3 to the outside of the decomposition tank 3 is deodorized by the combustion device 60, and the waste heat from the combustion device 60 causes the decomposition tank 3 to emit air. Is heated, a heat source for exhaust deodorization, a heat source for keeping the decomposition tank warm, and a heat source for heating the outside air can be commonly used by one combustion device 60. Therefore, since it is not necessary to separately provide these three heat sources, the number of components is reduced, and the cost of the garbage disposal apparatus 100 can be reduced.

Further, in this embodiment, since the environment maintaining unit 22 is integrated and mounted in the disassembling tank 3, the thickness of the main unit 100 can be reduced. It can be installed and used for running.

In this example, the case where the exhaust port 25 for circulating ventilation has a straight tip is described. However, the present invention is not limited to this, and the exhaust port 25 having a tapered discharge portion may be used. Good. With this configuration, the exhaust speed of the air 20B at the discharge portion is increased, and the drying effect in the decomposition tank 3 can be enhanced.

(2) Second Embodiment FIG. 9 is a conceptual diagram showing a configuration example of a garbage processing apparatus 200 as a second embodiment. In this embodiment, the air exhausted from the inside of the decomposition tank 3 to the outside of the decomposition tank 3 shown in FIG. 9 is directly combusted by the combustion unit 80, but without using the heat insulating member of the first embodiment. It is indirectly heated. With this configuration, gas consumption can be reduced. The components having the same reference numerals as those in the first embodiment have the same functions and the same materials, and thus the description thereof will be omitted.

The exhaust duct 27 A extending from the environment maintaining unit 22 of the garbage disposal apparatus 200 is connected to, for example, the air duct 66 of the blower 64 and to the mixing duct 81. The mixing duct 81 is a pipe material having a y-shape, and is used as a branch pipe or a merging pipe. The end of the mixing duct 81 is connected to a combustion unit 8 as a combustion means.
0 is attached. The combustion unit 80 has an inlet 80A
Is provided, and the mixing duct 81 is connected to the air inlet 80A. The combustion unit 80 has a combustion chamber 82,
A gas burner 83 is provided as a combustion tool. The gas exhausted from the inside of the decomposition tank 3 to the outside of the decomposition tank 3 is directly burned by the gas burner 83.

The combustion unit 80 has an exhaust port 80B.
Is provided, an exhaust duct 84 as a heat transfer member is connected, and waste heat from the combustion chamber 82 is transmitted to the decomposition tank 3.
For this heat transfer member, a copper tube having good heat conductivity is used. In this example, as the heat exchanger, the exhaust duct 84 is wound in a coil shape so as to surround the outer periphery of the decomposition tank 3 as it is, and the waste heat by the exhaust duct 84 and the air in the decomposition tank 3 exchange heat. You. By this heat exchange, the decomposition tank 3
Is indirectly warmed.

Next, the operation of the garbage disposal apparatus 200 will be described. In this example, a gas regulating valve 65 is connected to the gas burner 83, and the gas supply amount to the gas burner 83 is adjusted.
It is assumed that air is sent to the combustion chamber 82 by the blower 64.

For example, in the decomposition tank 3 shown in FIG.
When circulating B, the valve body 34 is completely closed by the solenoid 36 (not shown), and the air 20B is circulated in the decomposition tank 3 by the fan 29. At this time,
Exhaust port 25 of environmental maintenance unit 22 by fan 29
The air 20B that has flowed out is drawn into the intake port 24 of the environment maintaining unit 22 through the inside of the decomposition tank 3, and circulates between the decomposition tank 3 and the environment maintaining unit 22. Of course, also in this case, as in the first embodiment, the gas supply amount of the gas burner 83 is adjusted, and the inside of the decomposition tank 3 is maintained at a temperature at which microorganisms can easily be activated.

When the decomposition of garbage proceeds and moisture (saturated steam) or carbon dioxide increases in the decomposition tank 3, the air in the decomposition tank 3 is ventilated. In this case, the opening of the valve body 34 is adjusted by a solenoid 36 (not shown). At this time, the air with the offensive odor guided from the environment maintaining unit 22 into the combustion chamber 82 through the exhaust duct 27A is directly burned by the gas burner 83 in the combustion chamber 82. The exhaust gas 20 </ b> D after the combustion is exhausted from the exhaust port 21 while passing around the decomposition tank 3 through the exhaust duct 84.

Therefore, as in the first embodiment, the decomposition tank 3
The humid air or air with a bad smell inside and the dry air (outside air) outside the decomposition tank 3 can be exchanged by the fan 29 and the valve element 34, and the inside of the decomposition tank 3 which hinders the activity of microorganisms. Occurrence of condensation and lack of oxygen can be prevented.

In this example, the combustion unit 8 shown in FIG.
No air intake duct 26 is piped in 0. With this configuration, the combustion unit 80 can be made compact. Therefore, when the outside air 20C to be taken into the decomposition tank 3 from outside the decomposition tank 3 is warmed, a copper pipe 85 having a predetermined thickness is wound around the outside of the combustion unit 80 in advance as shown by a broken line in FIG. Piping. Then, this copper tube 85 is connected to the intake duct 26. Thus, the outside air 20C guided from the intake duct 26 to the copper pipe 85 can be indirectly warmed in the combustion chamber 82. Therefore, even when cold air that causes a temperature difference between the outside air 20C and the air 20B in the decomposition tank 3 is suddenly introduced into the cabinet 1, dew condensation can be prevented.

In each of the embodiments, the case where air is burned by the gas burners 63 and 83 has been described. However, the present invention is not limited to this, and the same effect can be obtained by burning with an oil burner or an electric heater.
