Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposer for decomposing garbage generated in restaurants, food processors and the like, and more particularly to a garbage disposer having a deodorizing device including a microorganism carrier. It is.

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open No. 11-16515 discloses a method for decomposing garbage generated in homes and restaurants.
A so-called garbage processing machine (garbage processing apparatus) as described in Japanese Patent Laid-Open Publication No. 6-206 is proposed.

[0003] In this conventional garbage processing machine, garbage introduced into a processing tank (bioprocessing tank) is stirred by a stirring means (stirring blade) together with a processing medium mixed with microorganisms, and the processing medium is fermented. The garbage is decomposed into gas and water to reduce the amount of 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 water is added to the processing medium by a sprinkler so that the value detected by the vessel becomes a suitable value.

Further, this prior art uses a deodorizing medium containing the same microorganisms as the microorganisms that inhabit the processing medium in the above-mentioned processing tank, and is provided with a deodorizing device for deodorizing exhaust gas from the processing tank using the microorganisms. The gas (odor) generated when the garbage is decomposed in the treatment tank is guided to the deodorizer together with the exhaust gas through the duct, and the exhaust gas is passed through the deodorizing medium in the deodorizer to remove the odor. 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 uses a deodorizing medium in which the same microorganisms as the microorganisms that inhabit the processing medium in the processing tank for decomposing and processing garbage are used in the deodorizing device, and the microorganisms are used to decompose from the processing tank. The odor contained in the exhaust is removed. When deodorizing exhaust gas by microorganisms like this,
In the treatment tank, the temperature and humidity of the treatment medium are set to a suitable state to ensure the proper decomposition processing performance of the garbage, as well as the environment in which the microorganisms can be actively activated. In order to ensure a suitable deodorizing performance of the deodorizing device, it is necessary to secure an environment in which the activity of microorganisms in the deodorizing device becomes active. However, in the above-mentioned prior art, no special consideration is given to securing the activity environment of microorganisms in the deodorizing device.

Further, as described above, in the above-mentioned conventional technology, the temperature and humidity of the processing medium in the processing tank are detected so that the activity environment of the microorganisms in the processing tank becomes suitable. Since the processing medium is heated and humidified so as to have a value, a large amount of water is contained in the exhaust gas guided from the processing tank to the deodorizing device via the above-described duct. As described above, when exhaust gas containing a large amount of moisture is passed through the deodorizing device, the moisture content of the deodorizing medium may increase beyond a suitable range with the progress of the decomposition process of the garbage, and microorganisms may be removed. There is a possibility that the activity environment will deteriorate and it will not be possible to demonstrate proper deodorizing ability.

[0007] The present invention has been made in view of the above, and an object of the present invention is to provide a garbage disposer capable of suitably maintaining the deodorizing performance of a deodorizing apparatus.

[0008]

Means for Solving the Problems (1) In order to achieve the above object, the present invention relates to a garbage processing machine for decomposing garbage, a processing tank containing microorganisms and a processing tank for receiving garbage. An intake path for introducing outside air to the processing tank, an exhaust path for exhausting the processing tank, and a deodorizing device provided in the exhaust path for deodorizing the exhaust gas;
The exhaust passage is provided upstream of the deodorizing device,
A heat exchanger that performs heat exchange between the exhaust gas and the intake air on the intake passage side.

As described above, in order to maintain the performance of the decomposition of garbage by microorganisms, the processing medium containing the microorganisms in the processing tank usually has an appropriate temperature and humidity. Therefore, usually, a large amount of water is contained in the exhaust gas from the processing tank. For example, as in the case of the processing tank, a deodorizing medium containing microorganisms is included as a deodorizing device, and the exhaust gas is passed through the deodorizing medium. In the case of using one that removes the odor contained in the exhaust gas, the moisture content of the exhaust gas may increase the moisture content of the deodorizing medium as the garbage decomposes. In this case, as described above,
The activity environment of microorganisms in the deodorizing medium may deteriorate, and the deodorizing ability of the deodorizing device may decrease.

Therefore, in the present invention, as described above, the heat exchanger is provided in the exhaust passage to the deodorizing device for deodorizing exhaust gas from the treatment tank for decomposing garbage, thereby improving the deodorizing device. Moisture contained in the introduced exhaust gas can be appropriately removed by the heat exchanger. Thus, for example, as described above, even when a device containing a deodorizing medium containing microorganisms is used as the deodorizing device, by suppressing an excessive increase in the water content of the deodorizing medium, It is possible to prevent the deteriorating activity environment from deteriorating and the deodorizing ability of the deodorizing device from deteriorating, thereby maintaining good deodorizing performance.

Further, when the water content of the deodorizing medium increases,
There is a possibility that the air permeability of the deodorizing medium is significantly reduced, and the pressure loss of exhaust gas in the deodorizing device is increased. As a result, the ventilation in the processing tank may be stagnated, and the water in the processing tank may not be able to be discharged, and an environment suitable for activating microorganisms in the processing tank may not be maintained. There is also a possibility that the decomposition processing performance cannot be sufficiently exhibited. Also in this case, in the present invention, by suppressing the increase in the water content as described above, the air permeability of the deodorizing medium can be ensured, so that there is also an effect that the decomposition treatment performance of garbage can be sufficiently ensured. .

(2) In the above (1), preferably,
The deodorizing device includes a deodorizing medium that mixes microorganisms and removes odor contained in the exhaust gas.

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

Next, when a predetermined switch on the operation panel 9 is operated to start the operation of the garbage disposal machine, the control device 32
By appropriately rotating and driving the stirring means 13 in the processing tank and appropriately stirring the inputted garbage with the processing medium,
The frequency of contact between microorganisms mixed with the processing medium and garbage is ensured, and the garbage is decomposed. At this time, the control device 32
According to the stored program, a command signal is sent to the drive device 21 of the agitation means 13 in the processing tank 13 at a predetermined rotation speed of, for example, about several rpm for about 1 to 2 minutes per hour, or in accordance with the operation of the operation panel 9 as appropriate. 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 ensure 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 accordance with 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 heat the processing medium appropriately.
Humidify. 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 inlet 4
6, outside air 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 is removed. The processing tank 10 is exhausted from the exhaust port 25 (see FIG. 4).
It is led out to ventilate the inside of 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 filtered by the vibrator 27. Is shaken off by being shaken. The driving control of the vibrator 27 is performed based on detection results of an anemometer for detecting the amount of exhaust air, a moisture content sensor 37, a temperature sensor 41 (or another temperature sensor for detecting an ambient temperature in the processing tank 10), and the like. When it is estimated that the filter 26 is clogged, the vibrator 27 may be driven or the operation panel 9 may be operated appropriately.

The exhaust gas led out of the treatment 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.
(See FIG. 8).

The exhaust gas from which moisture has been removed through the heat exchanger 47 passes through the heating duct 50 and is exhausted by the exhaust heater 51.
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 ensuring air permeability,
The activity environment of microorganisms mixed in the deodorizing medium is improved, and the pressure loss of exhaust gas is reduced. Also, at this time, the control device 32 executes, for example, a number r in accordance with the stored program.
A command signal for driving the deodorizing medium stirring means 65 is output to the driving device 70 at a predetermined rotation speed of about pm, once every half day for about 1 to 2 minutes, or in accordance with the operation of the operation panel 9 as appropriate. Further, at this time, the temperature and the water content of the deodorizing medium are measured by a temperature sensor 81 and a water content sensor 77, respectively, in order to secure a suitable activity environment for the microorganisms in the deodorizing device 60.
The controller 32 outputs a command signal to the exhaust heater 51 and the solenoid valve 89 of the water supply device 78 (see FIG. 7) according to the detection results, and appropriately heats and humidifies the deodorizing medium. 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.

Here, as described above, in the garbage disposer of the present embodiment, in order to keep the performance of decomposing garbage by microorganisms, a processing medium into which microorganisms are mixed in the processing tank 10 is appropriate. Temperature and humidity. Therefore, a large amount of water is contained in the exhaust gas from the processing tank 10. As described above, the exhaust gas from the processing tank 10 contains the deodorizing medium containing microorganisms and passes the exhaust gas through the deodorizing medium. When the deodorizing device 60 that removes the odor contained in the exhaust gas is used, the moisture content of the exhaust gas may cause the water content of the deodorizing medium to rise excessively with the progress of the decomposition process of the garbage. In this case, the activity environment of microorganisms in the deodorizing medium may deteriorate, and the deodorizing ability of the deodorizing device 10 may decrease.

Therefore, in the present embodiment, as described above, the heat exchanger 47 is provided on the upstream side of the deodorizing device 60 for deodorizing exhaust gas from the processing tank 10 for decomposing garbage. The moisture contained in the exhaust gas guided to the deodorizing device 60 can be appropriately removed by the heat exchanger 47. Accordingly, even when the deodorizing device 60 including the deodorizing medium containing the microorganism is used, an excessive increase in the water content of the deodorizing medium can be suppressed, and the activity environment of the microorganism in the deodorizing medium deteriorates. As a result, it is possible to prevent the deodorizing ability of the deodorizing device 60 from being reduced.
Good deodorizing performance can be secured.

FIG. 12 is a diagram showing a correlation between the water content of the deodorizing medium in the deodorizing apparatus and the pressure loss of exhaust gas passing through the deodorizing medium. As shown in FIG. 12, when the water content of the deodorizing medium is relatively low, since the surrounding water is small, almost no suction force acts between the individual medium particles in the deodorizing medium. And a certain degree of air permeability is secured. If the deodorizing medium is not stirred, as the moisture content of the deodorizing medium increases, moisture penetrates into the gaps between the finely laid medium particles, and the permeability decreases as the gaps become saturated with moisture. Then, as shown in FIG. 12, the pressure loss increases.

As can be seen from the correlation shown in FIG. 12, when the deodorizing device 60 for deodorizing exhaust gas with a deodorizing medium containing microorganisms as in the present embodiment, water is added by the moisture in the exhaust gas. When the water content of the deodorizing medium increases, the air permeability of the deodorizing medium may be significantly reduced, and the pressure loss of exhaust gas in the deodorizing device 60 may increase. As a result, ventilation in the processing tank 10 for performing the decomposition processing of garbage may be stagnated, and the water in the processing tank 10 may not be able to be discharged, which is suitable for activating microorganisms in the processing tank 10. Environment cannot be maintained, and there is a possibility that the performance of the garbage disposer, which is the original purpose of the garbage disposal machine, cannot be sufficiently exhibited. However, in the present embodiment, by suppressing the increase in the water content of the deodorizing medium as described above, the air permeability of the deodorizing medium can be ensured. There is also an effect that it can be sufficiently secured.

In the above description, the deodorizing medium stirring means 6
5 is provided to stir the deodorizing medium in the deodorizing apparatus 60 to make the water content of the deodorizing medium uniform and to ensure the air permeability of the deodorizing medium. In order to realize an appropriate deodorizing ability by preventing an excessive rise of the deodorizing medium, the deodorizing medium need not necessarily have a stirring function. For the same reason, in order to obtain the essential effects of the present invention, an exhaust heater for heating exhaust gas is not necessarily required.

In the above description, when the garbage is put into the garbage disposal main body 1, the opening / closing lid 6 is driven to open and close. However, the present invention is not limited to this. I do not care. Further, the deodorizing unit 2 for deodorizing exhaust gas is configured to be configured independently of the garbage disposal machine main body 1, but is not limited to this, and the deodorizing unit 2 and the garbage processing main body 1 are integrally configured. It does not matter. In these cases, a similar effect is obtained.
