[0004] The fixed blade 42 is provided on the lower inner wall of the kitchen waste container 41, and the rotary blade 43 is fixed to a rotating shaft 44 protruding from the bottom surface of the kitchen waste container 41. This rotating shaft 44
Is engaged with a drive shaft 47 via a drive motor 45 and a speed reducer 46.

A heater 48 and a stirring fan 49 are provided above the kitchen waste container 41 as heating means for kitchen waste.

Reference numeral 50 denotes a fan motor, which is disposed above the kitchen waste container 41 and the heater 48. Then, the upper portion of the kitchen waste is heated by the heater 48 and the stirring fan 49, and the heated kitchen waste is crushed by the rotary blade 43 driven by the drive motor 45.

The outer container 5 is provided around the outer periphery of the kitchen waste container 41.
The upper opening of the outer container 51 is covered with a lid 52.

In the above configuration, when the kitchen waste is put into the kitchen waste container 41 and the drying operation is started, the upper surface of the kitchen waste is heated by the heater 48 and the stirring fan 49.

At the same time, the kitchen refuse generates steam while being crushed by the fixed blade 42 and the rotary blade 43, and the drying proceeds.

When the drying is completed, the temperature is detected by a temperature detecting means (not shown), and the operation is terminated.

[0011]

In the above-mentioned conventional example, as is apparent from the figure, since the fan motor 50 for driving the stirring fan 49 is disposed above the heater 48, the fan 48 is heated by the heat of the heater 48. There is a drawback that the motor 50 is heated and the heat insulating material needs to be strengthened as a measure for reducing the temperature of the fan motor 50.

Further, since a turbo fan is used as the stirring fan 49, the wind is blown out from the center of the fan so as to be scattered to the outside, so that the dried garbage can be collected not only in the garbage container 41 but also in the turbo fan. Scattered and adhered to the surrounding area, and the cleaning property was extremely poor.

[0013]

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

When the garbage is put into the garbage 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 operate, 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 discharged from the exhaust port 26 to the outside of the main body 1, and at the same time, the suction port 24 is
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.

In this state, as the drying of the garbage proceeds, the temperature of the outer wall surface of the garbage container 4 also rises, and when the temperature reaches the temperature at which the drying of the garbage ends, the temperature is reduced to the fixed container 3. Is detected by the container sensor 27, and the power is turned off to terminate the operation.

In the above-mentioned present invention, the surface temperature of the heating means 12 rises to about 650 ° C. during the drying of the garbage put in the garbage storage container 4.

For this reason, in 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 blowing port 14 into which the hot air is blown into the garbage 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.

Also, the sirocco fan 13
a, the wind generated there is also blown out only toward the front of the circulation ventilation duct 16, smoothly flows into the kitchen waste container 4, heat-drys the kitchen waste, and then blows again. 13, so that the dried refuse does not scatter around.

Further, since the air blowing means 13 and the heating means 12 are installed inside the main body cover 2, the inspection of the air blowing means 13 and the heating means 12 and the degree of clogging of the garbage can be performed by simply opening the main body lid 2. Can be easily checked.

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.

[0052]

As described above, according to the present invention,
Since the ventilation means consisting of a fan motor and a sirocco fan was placed avoiding the heating means and above the garbage storage container,
Since the temperature of the atmosphere of the blowing means does not rise by the heating means and the like, and the circulating air cooled by the garbage returns to the blowing means, the blowing means is not heated unnecessarily.

Therefore, 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 container can be reduced.

Further, since the sirocco fan is used for the blowing means, the noise is small, and the wind generated there is also blown out only toward the front of the circulating air duct. Never scatter outside.

Therefore, the cleaning property can be remarkably improved, and a kitchen waste disposer with high drying efficiency can be provided.

Further, since the air blowing means and the heating means are installed inside the main body cover, it is possible to easily check the air blowing means and the heating means and check the degree of clogging of kitchen garbage simply by opening the main body lid. Can be.
