The present invention has the above-described configuration, and its operation will be described next.

When the garbage is put into the garbage storage container 4 and the drying operation is started, first, the heating means 12 composed of an electric heater is energized, and the electric motor 9 for driving the rotary stirring blade 6 is determined in advance. Forward and reverse rotations are repeated for the specified time.

Thereafter, when a predetermined time elapses, the fan motor 13b for driving the sirocco fan 13a of the blowing means 13 and the exhaust motor 23 for driving the cooling fan 22 are operated, and the inside of the kitchen waste container 4 is Circulate hot air through

The flow of the air blown by the blowing means 13 will be described. The air passing through the circulating air passage 16 c of the circulating air duct 16 is heated by the heating means 12 installed near the blowing port 14 and then heated by the heater 12. It is sprayed on the wall surface of the kitchen waste container 4 through the cover opening 17a.

Further, the garbage is applied to the kitchen garbage along the wall surface of the kitchen garbage container 4, passes through the heater cover opening 17b while drying the kitchen garbage, and flows from the circulation air passage 16e to the air blowing means 1e.
The circulation is performed in such a manner as to return to the sirocco fan 13a which is a component of the third embodiment.

The circulating air is supplied when the rotary stirring blade 6 is appropriately operated while supplying power to the heating means 12 so that the ambient temperature detected by the temperature sensor 28 is maintained at 110 ° C. to 140 ° C. The garbage is agitated and crushed by the fixed blade 5 attached to the inner wall of the garbage storage container 4 to generate steam and drying proceeds.

On the other hand, by the operation of the cooling fan 22, the air that has cooled the components inside the main body 1 is exhausted from the exhaust port 26 to the outside of the main body 1.
2 becomes lower than atmospheric pressure by the operation of
The atmosphere in the kitchen waste container 4 is sucked through the odor outlet 19 and deodorized through the catalyst deodorizer 20, mixed with cooling air from the exhaust port 26, and discharged to the outside of the main body 1.

By the suction and exhaust, the circulation ventilation duct 1
Since the pressure in the inside 6 is lower than that of the atmosphere, the circulation ventilation duct 1
The outside air is taken into the circulation ventilation duct 16 through the ventilation port 16 d provided in the air circulation duct 6.

When the drying of the garbage proceeds in this state, the temperature of the outer wall portion of the garbage storage container 4 also rises. Is detected by the container sensor 27, and the power is turned off to terminate the operation.

In the present invention, the surface temperature of the heating means 12 rises to about 650 ° C. while the garbage put in the garbage container 4 is being dried.

Therefore, according to the present invention, as described above, the sirocco fan 13a and the fan motor 13b, which are the components thereof, are
And a circulating air duct 16 avoiding above the kitchen waste container 4.
To prevent the blowing means 13 from being heated by the heating means 12.

Further, since the heating means 12 is arranged in the vicinity of the air blowing port 14 into which the hot air is blown into the garbage storage container 4 apart from the blowing means 13, heat loss is small and the garbage can be efficiently dried.

Thus, the blowing means 13 composed of the motor 13b and the sirocco fan 13a
As a result, the heat is not heated, the heat of the blowing means 13 is easily insulated, and a compact and efficient drying garbage disposer can be provided.

In the present embodiment, the heating means 12 has been described as an example of an electric heater, but it is needless to say that the same effect can be obtained even by electromagnetic induction heating.

[0049]

As described above, according to the present invention,
A fan means and a sirocco fan,
Since the heating means and the garbage storage container are arranged so as not to be above, the atmosphere of the blowing means does not rise in temperature by the heating means and the like, and the circulating wind cooled by the garbage returns to the blowing means. The blowing means is not heated unnecessarily.

Accordingly, it is easy to take measures against the temperature rise of the blowing means, the cost can be reduced, and the size of the kitchen waste disposal machine can be reduced.

Further, since the heating means is disposed in the vicinity of the air vent located immediately before the air is blown to the garbage storage container on the circulation air path, heat can be efficiently transmitted to the garbage.
