Further, the odor in the treatment tank 1 is adsorbed by the coconut shell activated carbon, so that the discomfort of the user can be suppressed when the garbage is put in, and the adsorbed odor is decomposed by the microorganisms so that the deodorizing effect is continued.

By driving the fan 22, the air in the processing tank 1 circulates through the circulation path to vaporize the water generated by the decomposition of the garbage and to supply oxygen necessary for activating the microorganisms. A part of the air circulated in the processing tank 1 is discharged to the exhaust pipe 18
Main body case 52 through the exhaust passage 19 and the exhaust port 42 from the rear side
It is prevented that the air in the processing tank 1 is exhausted to the outside and becomes over-humidified, and the efficiency of removing moisture in the processing tank 1 is improved.

If the frame body 50 is not completely attached to the shelf portion 44, the frame body 50 does not contact the hanging portion 46 of the lock member 45, and the lock member 45 does not rotate. The lock between 48 and the recess 47 of the slide shutter 8 is not released. Therefore, it is possible to prevent the slide shutter 8 from being opened in the state where the frame body 50 is absent or in the incompletely mounted state, and the usability can be improved.

Furthermore, when the drive switch 60 is operated when the carrier 63 is taken out, the electric motor 24 is driven for a predetermined time to rotate the stirring blade 29 forward and backward, and even if the carrier 63 contains water, the efficiency is improved from the opening 5. Can be discharged well.

The handle portion 12 of the slide shutter 8 is exposed on the side surface of the upper case 51, and the slide shutter 8 can be pulled out without removing the upper case 51, which is convenient.

Even when the frame body 50 is attached to the shelf portion 44, it is located in the space surrounded by the frame body 50. Therefore, after sliding the slide shutter 8 to open the opening 5 and taking out the carrier, the slide shutter 8 is again attached. When closing, even if the carrier attached to the collar portion 6 of the opening 5 is pushed by the slide shutter 8, the carrier is surely dropped from the tip portion of the slide shutter 8 into the bag attached to the frame body 50. You can

Recesses that form an air circulation path in the processing tank 1
Since 15 is formed integrally with the processing tank 1, the structure can be simplified and the cost can be reduced, and the temperature inside the processing tank 1 can be reduced as compared with the case where the circulation path is provided outside the processing tank 1. It can prevent the deterioration.

Since the circulation path is formed on the back side of the processing tank 1, when the user inputs the organic substance, the opening for discarding the organic substance is close to the position of the user, and the usability can be improved. Since the exhaust port 42 is formed in the lower rear portion of the main body case, the exhaust port is located farthest from the user's position, and the user's discomfort due to the smell of the air in the processing tank can be suppressed.

Further, since the joint between the lower case 38 and the upper case 51 covering the processing tank 1 is located at the lowermost position of the processing tank 1, that is, below the drive mechanism such as a gear, the electric motor 24
When some abnormality occurs in the gears 33 to 36 and the heater 4 interposed between the stirring blade 29 and the stirring blade 29, the upper case 51 is removed for maintenance to expose the processing tank 1 and the drive mechanism, Maintenance can be performed easily.

Further, when the control board 21 is attached to the upper case 51 side when removing the upper case 51 for maintenance because the control board 21 and the like for controlling the drive mechanism are attached to the processing tank 1. As described above, it is not necessary to attach / detach the electrical contact or the like between the control board 21 and the drive mechanism, and the workability can be improved.

In the above embodiment, the drive switch
Although the control circuit 56 is configured to drive the electric motor 24 for a predetermined time when the 60 is operated, the electric motor 24 may be driven only while the drive switch 60 is operated. With this configuration, the electric motor 24 can be stopped according to the state of taking out the carrier 63, the carrier 63 overflows from the bag, or the carrier 63
