(Embodiment 1) Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a garbage storage container, and 2 denotes a heating means comprising a sheath heater or the like. In this embodiment, the heating means is heated from below the garbage storage container 1.
The position of the heating means 2 is not limited to this position. Reference numeral 3 denotes a temperature detecting means disposed on the bottom rear surface of the garbage storage container 1 so as to detect an ambient temperature in the garbage storage container 1. The heating means 2 is turned on by the control means 6 based on the output of the temperature detecting means 3. / OFF control and heating control to maintain a predetermined temperature. Reference numeral 7 denotes a stirring blade rotatably arranged in the garbage storage container 1 and is driven by a drive motor 8.

The upper portion of the garbage storage container 1 is openably and closably covered by a lid 4, and the outside air sucked from the outer periphery of the lid 4 through the hollow portion 10 of the lid 4 is centered on the lid 4. This is a configuration in which the garbage is poured into the garbage storage container 1 from the provided intake port 5. An exhaust hole 8 is provided on the back surface (the surface on the side of the garbage storage container 1) of the lid, and the exhaust hole 14 communicates with the exhaust passage 11, and a downstream side of the exhaust passage 11 is provided for deodorization.

An exhaust fan 13 is connected to the exhaust port 13 of the catalyst 12, and the gas (including steam) generated from the garbage 20 in the garbage storage container 1 is discharged to the exhaust hole 14 by the suction force of the exhaust fan 13. Exhaust passage 1
1. Further, the air is exhausted to the outside through the catalyst 12 for deodorization.
The control means 6 controls the drive of the drive motor 8 and the exhaust fan 9 in addition to the heating means 2.

The operation of the above configuration is as follows.
In FIG. 2, the heating and drying process is started (time t0).
Then, the heating means 2 is turned on. Then, the temperature of the garbage 20 put into the garbage storage container 1 rises, and the output of the temperature detecting means 3 also rises later than the temperature rise. When the temperature detected by the temperature detecting means 3 reaches a predetermined temperature T0 (for example, 130 ° C.), the control means 6 turns off the heating means 2. Then, the detected temperature of the temperature detecting means 2 falls below the predetermined temperature T0 again, and at this time, the control means 6 turns on the heating means 2 again.

When the temperature reaches the predetermined temperature T0, the control means 6 operates the drive motor 8 intermittently, and the stirring blades 7 crush and agitate the garbage. The garbage is heated and dried by the stirring operation and the heating means 2.

In the heating / drying process, the control means 6 operates the exhaust fan 9 while the heating means 2 is turned off, and exhausts the gas containing water vapor generated from the garbage from the garbage container 1. Further, the operation of the discard fan 9 is stopped while the heating means 2 is ON. Thus, the heating means 2 for increasing the temperature in the garbage storage container 1
Since the exhaust is not performed during the ON period, the heating effect is enhanced. The higher the temperature of the catalyst 12 that absorbs the odor, the better the efficiency. Therefore, when the temperature detecting means 3 is at or below the predetermined temperature T0 and the heating means 2 is ON, the exhaust fan 9 is turned off to obtain the predetermined temperature T0. It is also possible to prevent lower discards from flowing into the catalyst 12 and lowering its deodorizing performance. Conversely, when the temperature detecting means 3 is at or above the predetermined temperature and the heating means 2 is OFF, the exhaust fan 9 for exhaust is turned on.
N enhances the effect of the catalyst 12 for absorbing odor.
