The present device configured as described above has an upper cover 2
2 is opened and organic matter such as garbage is treated through the inlet 21 into the treatment tank 1
It is used by putting it in. The organic matter put into the treatment tank 1 is taken into the carrier A by the forward and reverse rotation of the stirring body 3 driven by the stirring motor M, and is decomposed by the activity of the microorganisms living in the carrier A.

In order to prevent dew condensation and maintain the intake air temperature at an appropriate temperature, the ventilation fan F is controlled in accordance with a flowchart described later.
It is always performed to discharge water (steam) and gas generated by the decomposition process. Further, the drive control of the stirring motor M is to periodically stir the carrier A inside the processing tank 1
It is carried out intermittently in order to take in air and release moisture and gas generated in the carrier A. By such an operation, the inside of the treatment tank 1 is maintained in an environment suitable for the activity of the microorganisms living in the carrier A, and the organic matter taken in the carrier A leaves a small amount of composted residue, It is decomposed into gas containing carbon dioxide as a main component and water.

With the progress of the decomposition treatment, the carrier A
In the residue, hardly decomposed materials (plastic bags, disposable chopsticks, shells, etc.) that accumulate along with residues after decomposition and organic matter are accumulated,
Since the habitat of the microorganisms in the carrier A deteriorates and the treatment capacity decreases, the deteriorated carrier A needs to be replaced. Deterioration of the carrier A can be determined by an increase in the surface level of the carrier A in the treatment tank 1, but in a normal use state in a general household, at a cycle of about once every three to six months. You just have to exchange.

At the time of this exchange, first, the deteriorated carrier A inside the processing tank 1 is taken out. This removal is performed by holding the handle 80 integrally formed on the front surface of the exterior cover 8 from the outside of the exterior case 2, removing the exterior cover 8 so as to pull it upward and forward, opening the removal opening 26, and then opening the shutter 7. Is put on the handle 70 integrally formed on the front surface, pulled out forward, the discharge port 19 on the lower front surface of the processing tank 1 is opened, and the carrier A inside the processing tank 1 is discharged through the discharge port 19 to the discharge chute 25. The carrier A is dropped down, the carrier A is scraped forward along the slope of the discharge chute 25, and the carrier A is collected, for example, in a collection bag whose bag opening faces the outlet 26.

After the removal is completed in this way, first, the shutter 7 is mounted to seal the discharge port 19, and then the outer cover 8 is mounted to close the discharge port 26. New carrier is charged from. After the replacement is completed in this way, the organic substance processing can be performed by restarting the operation described above.

Next, a control example of the panel heater H2 characteristic of the present invention will be described with reference to the flowchart of FIG.

When the control is started simultaneously with the start of the operation of the apparatus, first, the outside air temperature To detected by the outside air temperature sensor So is set to a predetermined temperature (first set value).
It is checked whether it is lower than a (determination S1). Note that, as the predetermined temperature a, a minimum temperature that does not effectively lower the performance of decomposing microorganisms is set. Here, if the outside air temperature To is lower than the predetermined temperature a, the panel heater H2 is continuously operated (continuously energized) so that the maximum heating power of the panel heater H2 is obtained (determination S1).
Y → process S2).

Thus, the panel heater H in the upper lid 22 is
2 is heated, the entire surface of the inner lid 22a to which the inner lid 2 is attached is heated.
The cool air taken into the processing tank 1 from the suction holes 13 located around the periphery 2a is efficiently warmed. Therefore, the degradation of the decomposition processing performance due to ventilation when the outside air temperature is low can be suppressed. At the same time, since the inner lid 22a itself is heated, no dew condensation occurs on the inner lid 22a.

On the other hand, if the outside air temperature To is equal to or higher than the predetermined temperature a (N in judgment S1), it is checked whether the outside air temperature To is lower than the tank temperature Ti detected by the tank temperature sensor Si. (Decision S3). Here, if the outside air temperature To is lower than the tank temperature Ti (Y in judgment S3), the difference, that is, the tank temperature Ti−the outside temperature To = ΔT is larger than the second predetermined value b, and the third Or less (b <Δ
It is checked whether T ≦ c) (judgment S4). The second set value b is set to a temperature difference at which dew condensation starts to occur on the inner lid 22 according to the thermal conductivity between the upper lid 22 front surface and the inner lid 22a rear surface, and the third set value c is a temperature at which dew condensation increases. The difference is set.

If the condition of b <.DELTA.T.ltoreq.c is satisfied in the above judgment S4, there is not much condensation, but the on / off ratio of the panel heater H2 is constant (for example, 1: 1). Driving by driving (Y in judgment S4 → processing S
5). Even in the heating in which the capacity of the panel heater H2 is suppressed, since the difference between the outside air temperature and the inside temperature of the tank is not so large, it is possible to prevent dew condensation from occurring on the inner lid 22a.

On the other hand, if the condition of b <ΔT ≦ c is not satisfied in the judgment S4, then the temperature difference ΔT is changed to the third set value c.
It is checked whether it is larger (decision S4)
N → determination S5). Here, if the temperature difference ΔT is larger than the third set value, a large amount of dew condensation occurs. Therefore, the panel heater H2 is continuously operated so that the maximum heating power of the panel heater H2 is obtained. (Y in determination S6 → process S2). Accordingly, even when the outside air temperature is lower than the inside temperature of the tank and the temperature difference is large, it is possible to prevent the dew condensation from occurring on the inner lid 22a.

As described above, since the dew condensation on the upper lid 22 is prevented, when the upper lid 22 is opened, the dew water does not flow around the inlet 21. As a result, the moisture generated by the decomposition treatment of the organic matter can be smoothly discharged to the outside of the tank as water vapor.

In the above judgment S3, the outside air temperature To
Is not lower than the tank temperature Ti, and when neither of the conditions of the judgment S4 and the judgment S6 is satisfied, that is, when the temperature difference ΔT is smaller than or equal to the second set value b, the inner cover 22
a, no condensation occurs on the panel heater H2.
Does not drive, or stops if it is in operation (judgment S3
N → process S7 or N → judgment S6 → process S7).

After the processes S2, S5 and S7, the process returns to the first judgment S1 and repeats the above process.
Operation control.

The desired object of the present invention can be achieved by a configuration in which the panel heater H2 is always energized upon the start of operation of the present apparatus or a configuration in which a switch is provided so that the user can energize as needed. By controlling the panel heater H2 based on the outside air temperature and the inside temperature of the tank,
Since the power consumption is small and the user does not have to do much work, it is possible to efficiently realize the prevention of dew condensation on the upper lid 22 and the suppression of degradation of the decomposition processing performance due to the cool air.

Further, by controlling the panel heater H2 in the continuous operation and the intermittent operation at a constant on / off ratio as described above, the configuration and control of the panel heater H2 are simplified.

If a panel heater capable of setting the temperature using a thermistor is used, the process S2 in the flowchart of FIG. 5 is set to “operation at a high set temperature (for example, 60 ° C.)” and the process S5 is set to a “low set temperature (for example, By “operating at 40 ° C.”, the same function as described above can be realized with higher accuracy.
