In the embodiment constructed as described above, with the discharge lid 13 closed, the input lid 12 is opened, a predetermined amount of kitchen waste is put into the storage tank 10, and the input lid 12 is closed. At the same time, when the key lock device 70 is changed from the unlocked state to the locked state using a key (not shown) managed and held by the administrator and the start switch 107 is pressed and operated, all the relays 105, 106,
108 is energized and the normally open contacts 105a, 106a, 1
08a1, 108a2 and 108a3 are closed, so that the electric heaters 15, 45 and 53a are controlled under the control of the controller 100.
, The electric motors 31, 43, and 52 are started, and the timer 110 is started to start timing. Therefore, the bottom 11c of the storage tank 10 is heated from the outside by the electric heater 15, the inside air in the storage tank 10 is heated by the electric heater 45, and the catalyst (not shown) of the deodorizer 53 is heated by the electric heater 53a. At the same time, the stirring member 20 is rotationally driven by the electric motor 31, the hot air circulation fan 42 is rotationally driven by the electric motor 43, and the exhaust fan is rotationally driven by the electric motor 52.

For this reason, hot air is blown toward the kitchen garbage in the storage tank 10 and circulates. At the same time, the hot air circulating to the hot air circulating fan 42 is added to the outside air through the intake passage A, and is simultaneously circulated to the hot air circulating fan 42. Part of the hot air is released to the atmosphere through the exhaust duct 51, the exhaust fan, and the deodorizing device 53 (see arrows in FIGS. 3 and 4). In addition, the kitchen waste is heated and dried from below by the bottom 11c of the storage tank 10, and heated and dried from above by hot air,
The water vapor generated from the kitchen garbage moves upward using the flow of hot air as a carrier and is discharged to the atmosphere together with a part of the hot air through the exhaust duct 51, the exhaust fan, and the deodorizing device 53. Therefore, the drying operation of the kitchen waste is started in a state where the deodorizing exhaust is performed by the exhaust device 50.

By the way, when the key lock device 70 is unlocked or the discharge lid 13 is opened at the time of the pushing operation of the start switch 107, the lock detection switch 102 or the door switch 103 is opened. The relays 105 and 106 are not energized, and the normally open contacts 105a and 106a cause the electric heaters 15 and 106 to operate.
45, the electric motors 31, 43 and the timer 110 are not energized. For this reason, although the exhaust device 50 can be started, the drying operation of the kitchen waste cannot be started. When the key lock device 70 is changed from the unlocked state to the locked state, the discharge port cover 13 is opened.
Is closed, the lock detection switch 102 and the door switch 103 are closed, and the relays 105 and 106 are energized, so that the electric heaters 15 and 45 and the electric motor 31 and
43 and the timer 110 are energized, and the garbage drying operation starts in a state where the deodorizing exhaust is performed by the exhaust device 50.

The above-mentioned operation of drying the garbage continues until the elapsed time after the start reaches the set time of the timer 110, during which time the heating temperature of the bottom 11c of the storage tank 10 and the garbage are sprayed toward the garbage. The temperature of the hot air is maintained at approximately 127 to 130 ° C. (a temperature range set in consideration of the fact that oil, resin, and vinyl are contained in the garbage), and the temperature of the catalyst of the deodorizing device 53 is substantially maintained. 2
The temperature is maintained at 80 to 300 ° C. (the temperature range in which the catalyst functions effectively). When the elapsed time after the start of the drying process operation reaches the set time of the timer 110, the normally closed contact 110b of the timer 110 is opened to cut off the power supply to the relay 108, and thereby the normally open contact 108a1,
108a2 and 108a3 are opened and the electric heaters 15 and 4 are opened.
5, 53a, the electric motors 31, 43, 52, and the timer 110 are cut off, and the deodorizing exhaust and drying of the garbage are completed, and the timer 110 is reset.

After the deodorizing exhaust and the drying operation of the garbage are completed as described above, if the discharge switch (not shown) is pushed and operated with the discharge opening lid 13 opened,
The electric motor 3 is provided by another energizing circuit not shown in FIG.
1 is energized, and the stirring member 20 is continuously rotated clockwise in FIG. 4, so that the kitchen waste after the heating and drying treatment in the storage tank 10 is discharged by the blades 23 of the stirring member 20 into the discharge port 1.
1b, and some of the blades 23
However, the remaining part falls from the blade 23 to the discharge port 11b, is automatically discharged out of the storage tank 10 through the discharge port 11b, and is stored in the container 18 through the hopper 16. In a state in which the opening lid 12 is open or a state in which the container 18 is not set at a predetermined position (detected by each switch (not shown)), the rotation driving device 30 is activated even if the discharge switch is pushed. The agitation member 20 is configured to stop when the pushing operation of the discharge switch is stopped. Further, the garbage that has been heated and dried and stored in the container 18 can be taken out together with the garbage bag while the container 18 is tilted as shown by the imaginary line in FIG.

That is, the heating operation by the electric heater 15 and the stirring member 20
As a result, the stirring operation and the heating / blowing operation by the hot air circulation device 40 are all stopped. Therefore, safety during the drying operation of the apparatus can be ensured, and odor generation from the garbage is suppressed. At this time, the inside air inlet 1 in the storage tank 10 is also operated by the exhaust device 50 that is operating.
It is possible to prevent the user from inhaling the odor through the inlet 11a by suppressing the discharge from the inlet 1a.

Further, in this embodiment, the outside air is sucked into the suction side of the hot air circulation fan 42 through the intake passage A by the rotation drive of the hot air circulation fan 42 by the electric motor 43, and is assimilated into the circulating hot air by the hot air circulation fan 42. While circulating, the inside air in the storage tank 10, that is, a part of the hot air containing water vapor is discharged out of the storage tank 10 through the exhaust device 50. Therefore, the inhalation of the outside air can suppress the saturation of the water vapor in the inside air, thereby promoting the generation of water vapor from the garbage, thereby also improving the heating and drying efficiency of the garbage. In addition, outside air suction
Since the hot air circulation fan 42 provided for circulating the hot air in the storage tank 10 is used, the configuration can be made simpler and cheaper than when using the suction fan and the driving device. .

Can be cooled also by the outside air sucked into the storage tank 10, and the overheating damage of the electric motor 43 can be suppressed, whereby the durability of the electric motor 43 can be improved and the storage tank can be cooled. The outside air sucked into 10 can be preheated by the electric motor 43,
The cooling of the hot air by the outside air in the storage tank 10 can be suppressed, and the heat utilization efficiency in the storage tank 10 can be improved.

Also, in the present embodiment, the housing tank 10 is formed so that the drive shaft 42a of the hot air circulating fan 42 passes therethrough.
Since the through hole 11d provided in the tank body 11 itself is configured to be the intake opening of the intake passage A, there is no need to separately provide an intake opening, so that the cost can be reduced and the structure can be simplified.
