A so-called garbage processing machine (garbage processing apparatus) as described in Japanese Patent Laid-Open Publication No. 6-206 is proposed.

[0003] In the above-mentioned conventional garbage processing machine, the garbage thrown into a processing tank (bioprocessing tank) is stirred by a stirring means (stirring blade) together with a processing medium containing microorganisms, and the fermentation action of the processing medium is performed. Is used to decompose garbage into gas and water, thereby reducing garbage. At this time, in this conventional technique, in order to activate the microorganisms in the processing tank, a temperature detector and a humidity detector for detecting the temperature and humidity of the processing medium containing the microorganisms are provided. The processing tank is appropriately heated by a heater or the processing medium is humidified by a sprinkler so that the value detected by the vessel becomes a suitable value.

Further, this prior art uses a deodorizing medium mixed with the same microorganisms as the microorganisms that inhabit the processing medium in the processing tank described above, and deodorizes an exhaust gas from the processing tank by the microorganisms (deodorizing tank). The gas (odor) generated when the garbage is decomposed in the treatment tank is guided to the deodorizing device together with the exhaust gas through the duct, and the exhaust gas is passed through the deodorizing medium in the deodorizing device to remove the odor. After removal, the exhaust fan actively releases the air.

[0005]

However, the above prior art has the following problems. That is, as described above, the above-described conventional technology has a structure in which a deodorizing medium mixed with the same microorganism as the microorganism in the processing tank for decomposing garbage is used in the deodorizing device, and the deodorizing medium exhausts the processing tank. To remove the odor contained in When the odor is removed by the microorganisms in this way, the treatment medium in the treatment tank has an appropriate temperature environment in which the activity of the contaminated microorganisms can be activated, as well as the deodorization medium in the deodorization device. In addition, there is a temperature environment in which the contaminated microorganisms can be actively activated.

In the above prior art, as described above,
In order to ensure a suitable activity environment for the microorganisms in the treatment tank, the treatment medium in the treatment tank is heated or hydrated. Not particularly considered. Also, for example, when using a garbage disposer at a time or place where the outside air temperature is relatively low, heat is released and the temperature of the deodorizing medium decreases,
As a result of the deterioration of the activity environment of the microorganisms mixed in the deodorizing medium, the deodorizing ability of the deodorizing device may be reduced.

[0007] The present invention has been made in view of the above, and an object of the present invention is to maintain a suitable temperature environment for microorganisms in a deodorizing device and to ensure appropriate deodorizing performance of the deodorizing device.

When the deodorizing medium containing microorganisms is used for the deodorizing apparatus, the temperature of the processing medium in the processing tank is set to a suitable value, and a temperature environment in which the mixed microorganisms are actively activated is secured. Similarly, in order to ensure a suitable deodorizing performance of the deodorizing device using microorganisms, it is necessary to ensure a temperature environment in which the activity of the microorganisms becomes active in the deodorizing medium in the deodorizing device.

In the present invention, as described above, the surroundings of the deodorizing device for deodorizing exhaust gas from the treatment tank for decomposing garbage are covered with a heat retaining member, so that, for example, when the outside air temperature is relatively low. Even when the garbage disposer is operated at a location or place, the heat in the heat retaining member is suppressed from being released to the outside, and the atmosphere inside the heat retaining member is kept warm to prevent the temperature of the deodorizing medium from dropping. can do.
Thereby, an appropriate temperature environment of the microorganisms in the deodorizing medium can be maintained, and the appropriate deodorizing performance of the microorganism deodorizing device can be secured.

Can be reduced. In addition, for example, the temperature of the deodorizing medium can be kept at an appropriate temperature with a simple structure because the ambient temperature in the heat retaining member can be raised by utilizing the heat released by the exhaust fan. Can be maintained in a temperature environment suitable for microorganisms.

(3) In the above (1) or (2), preferably, the deodorizing medium in the deodorizing device is the same as the processing medium in the processing tank.

Output. Also, the input of garbage is detected (specifically, for example, the input lid 6 by a limit switch).
Or the change of the weight of the processing tank 10 by the load cell 35), and the drive may be controlled at a predetermined number of revolutions under the above-described drive conditions. Further, as shown in FIG. 11, the drive device 21 may be controlled by an inverter via an inverter.

At this time, in order to secure a suitable activity environment of the microorganisms in the processing tank 10, the temperature and the water content of the processing medium are detected by the temperature sensor 41 and the water content sensor 37, respectively. In response to these detection results, a command signal is output to the processing tank heater 42 and the solenoid valve 88 of the water supply device 38 (see FIG. 5) to appropriately heat and humidify the processing medium. When water is supplied to the processing medium, the stirring means 13 in the processing tank is driven to make the water content of the processing medium uniform.

On the other hand, in order to supply fresh oxygen to the microorganisms mixed in the processing medium in the processing tank 10, the intake 4
6 is introduced into the treatment tank 10 through the heat exchanger 47, the intake duct 48, the intake hose 3 and the like, and gas generated in the treatment tank 10 due to the decomposition of garbage. And the like are exhausted to the outside of the processing tank 10 from the exhaust port 25 (see FIG. 4) to ventilate the processing tank 10. At this time, the suspended matter in the treatment tank 10 such as the treatment medium finely divided by the stirring is collected by the filter 26 (see FIG. 4), and the suspended matter deposited on the filter 26 is appropriately removed by the vibrator 2.
The filter 26 is shaken by being excited by the filter 7. The driving of the vibrator 27 is controlled by an anemometer for detecting the amount of exhaust air, a moisture content sensor 37, a temperature sensor 41, and the like.
The controller 32 estimates that the filter 26 is clogged in response to a change in the state quantity determined based on the detection result of (or another temperature sensor for detecting the ambient temperature in the processing tank 10). In this case, the vibrator 27 may be driven or the operation panel 9 may be operated appropriately.

The exhaust gas led out of the processing tank 10 is led into the deodorizing unit 2 through the exhaust hose 4 and then flows into the heat exchanger 47 through the exhaust duct 49, where the relatively low-temperature outside air is discharged. The mixture is cooled by heat exchange with water to remove the contained water. The condensed water is supplied to the drain 52 (see FIG. 8) and the hose 53 (see FIG. 8) as described above.
Through the container 54 (see FIG. 8).

The exhaust gas from which moisture has been removed by passing through the heat exchanger 47 passes through the heating duct 50,
After being heated by the exhaust fan 55, the exhaust fan 55 actively sends the air to the deodorizing device 60 via the deodorizing device introduction duct 59 to decompose and remove the odor contained by the microorganisms mixed in the deodorizing medium in the deodorizing device 60. At this time, the control device 32 appropriately rotates and drives the deodorizing medium stirring means 65 and stirs the deodorizing medium appropriately, thereby making the water content of the deodorizing medium uniform and securing the gas permeability of the deodorizing medium, The activity environment of microorganisms mixed in the deodorizing medium is improved, and the pressure loss of exhaust gas is reduced. At this time, the control device 32 performs the operation according to the stored program at a predetermined rotational speed of, for example, about several rpm at intervals of once every half day.
A command signal for appropriately driving the deodorizing medium stirring means 65 is output to the driving device 70 for about 2 minutes or appropriately in accordance with the operation of the operation panel 9. Further, at this time, in order to secure a suitable activity environment of the microorganisms in the deodorizing device 60, the temperature and the water content of the deodorizing medium are detected by the temperature sensor 81 and the water content sensor 77, respectively. Exhaust heater 51 and water supply device 78 (see FIG. 7)
A command signal is output to the electromagnetic valve 89, and the deodorizing medium is appropriately heated and humidified. When water is supplied to the deodorizing medium, the deodorizing medium stirring means 65 is driven to equalize the water content of the deodorizing medium.

The exhaust gas from which the odor has been removed by passing through the deodorizing device 60 flows into the ultraviolet sterilizing unit 83 through the duct 82, is sterilized, and finally discharged to the atmosphere through the exhaust pipe 85. . At this time, the suspended matter in the deodorizing device 60 such as the deodorizing medium finely divided by the stirring is collected by the filter 86 (see FIG. 7), and is prevented from scattering outside the garbage processing machine.

Hereinafter, the effects obtained by the above configuration in the garbage disposer of this embodiment will be sequentially described. (1) Ensuring proper deodorizing performance Here, in the case of using the deodorizing device 60 that deodorizes exhaust gas with a medium containing microorganisms as in the garbage disposal machine of the present embodiment, as described above, the garbage disposal In the machine body 1, the processing tank heater 42 and the like are appropriately operated to
The temperature or the like of the processing medium within 0 is set to a suitable value to ensure a temperature environment in which the mixed microorganisms actively activate. As described above, in order to ensure a suitable deodorizing performance of the deodorizing device 60, the processing medium in the processing tank 10 needs to have a favorable activity environment for microorganisms. Therefore, it is necessary to secure a temperature environment in which the activity of microorganisms becomes active. In addition, for example, when operating the garbage disposer at a time or place where the outside air temperature is relatively low, heat is released and the temperature of the deodorizing medium decreases,
As a result of the deterioration of the activity environment of the microorganisms mixed in the deodorizing medium, the deodorizing ability of the deodorizing device 60 may be reduced.

In the present embodiment, as described above,
By covering the periphery of the deodorizing device 60 for deodorizing exhaust gas from the processing tank 10 for decomposing garbage with the heat retaining member 91, for example, the garbage processing machine is operated at a time or place where the outside air temperature is relatively low. Even in the case, the heat in the space inside the heat retaining member 91 is suppressed from being released outside the deodorizing unit 2,
By keeping the atmosphere in the heat retaining member 91 (that is, the atmosphere around the deodorizing device 60) warm, it is possible to prevent the temperature of the deodorizing medium from lowering. Thereby, an appropriate temperature environment of microorganisms in the deodorizing medium can be maintained, and appropriate deodorizing performance of the deodorizing device 60 can be secured.

Further, since operating devices such as the exhaust fan 55 and the exhaust heater 51 are provided in the heat retaining member 91 together with the deodorizing device 60, heat in the heat retaining member 91 is utilized by utilizing heat released from these operating devices. Since the ambient temperature can be raised, the deodorizing medium can be kept at an appropriate temperature with a simple structure, and a temperature environment more suitable for microorganisms mixed in the deodorizing medium can be maintained.

(2) Noise Reduction Also, as in the present embodiment, an exhaust fan 55 is provided in an exhaust path from the inside of the processing tank 10 of the garbage processing machine body 1 to actively ventilate the processing tank 10. When the exhaust fan 55 is used, the exhaust fan 55 drives the rotating blades such as the built-in turbo blower by the driving device 57 to generate an air flow in the exhaust path such as the above-described duct 58. In some cases, the driving noise of the garbage and the wind noise of the rotating blades leaked out of the garbage disposal machine.

In this embodiment, the exhaust fan 55
In addition, since the driving device 57 is covered with the heat retaining member 91 together with the deodorizing device 60, the above-described driving sound and wind noise can be prevented from leaking out of the garbage disposal machine, and noise to the surrounding environment can be reduced. can do.

In this embodiment, the exhaust fan 55 is provided in the heat retaining member 91 in order to obtain the effect of noise reduction. However, the proper deodorization of the deodorizing device 60 which is an essential effect of the present invention. It is not always necessary to provide the exhaust fan 55 in the heat retaining member 91 as long as the performance is ensured. In short, if at least the deodorizing device 60 (strictly, the medium container 63) is covered by the heat retaining member 91, a heat retaining effect of the deodorizing medium can be obtained, and a decrease in the deodorizing performance of the deodorizing device 60 can be suppressed. be able to.

In the present embodiment, the heat insulating member 9
Although the description has been made by taking urethane as an example of the first material, the material is not limited to this. For example, the heat retaining member 91 may be made of, for example, styrene foam, and the heat retaining member 91 may be composed of a member having heat insulating properties.

Further, in the present embodiment, the deodorizing medium stirring means 65 is provided to stir the deodorizing medium in the deodorizing device 60 to make the water content of the deodorizing medium uniform and to ensure the air permeability of the deodorizing medium. However, such a function of stirring the deodorizing medium is not necessarily required. Further, when the garbage is put into the garbage processing machine main body 1, the opening / closing lid 6 is configured to be opened / closed. However, the present invention is not limited to this. For example, the garbage may be manually opened / closed. Furthermore, although the deodorizing unit 2 for deodorizing exhaust gas is configured to be configured independently of the garbage disposal machine main body 1, the present invention is not limited to this, and the deodorizing unit 2 and the garbage processing machine main body 1 are integrally configured. It does not matter. In these cases, a similar effect is obtained.
