The operation of the kitchen garbage disposer configured as described above will be described. The garbage put into the garbage storage container 12 is agitated by the rotary blade 14 and crushed by the rotary blade 14 and the fixed blade 13. The container 11 heated by the heater 30 transfers heat to the garbage storage container 12 from the entire circumference, and the temperature in the garbage storage container 12 rises to heat the garbage. Steam is generated from the heated garbage and discharged from the first discharge port 20 on the upper part of the garbage storage container 12.

The discharged steam is supplied to the fan 26 and the motor 2
The air is sucked by the suction means 7, passes through the suction section 39 and the exhaust hose 21, and is then discharged outside after the odor is removed by the deodorizing device 22. Therefore, there is no odor during drying,
Although the crushed and dried garbage remains in the garbage storage container 12, the garbage is reduced in volume, easily discarded, and dried to reduce water activity, so that it does not rot or generate mold. . Therefore, until the garbage container 12 is full,
One after another, the garbage can be put on the dried garbage and dried. Therefore, compared to garbage, it is possible to convert the garbage into garbage that is easier to handle, reduce in weight and easier to process.

Since the garbage storage container 12 has a mortar shape, the gap between the outer wall of the garbage storage container 12 and the inner wall of the container 11 is set so as to gradually narrow upward. Therefore, the temperature of the bottom of the container 11 close to the heater 30 becomes high (about 250 ° C.), but since the gap between the garbage storage container 12 and the container 11 is large at the bottom, the temperature of the garbage storage container 12 can be kept low. (About 130 ° C.).

On the other hand, as the side of the container 11 goes upward, the heat of the heater 30 is less likely to be transmitted, and the temperature decreases (about 16).
(0 ° C.) because the gap between the garbage storage container 12 and the container 11 is narrow, the heat transfer to the garbage storage container 12 is improved, and the temperature is almost the same as the bottom surface (about 130 ° C.).

Therefore, the garbage container 12 is heated to a substantially uniform temperature in the vertical direction, so that the garbage container 12 exhibits the same heating capacity as the conventional method of blowing in hot air even at a relatively low temperature, thereby reducing garbage. Can be dried in time. In addition, even if the heater temperature is high, the temperature of the garbage storage container 12 can be suppressed to a temperature that can be endured by the heat-resistant resin. Can be. In addition, since it can also be formed of a resin, its effect can be enhanced, for example, the surface releasability can be improved and sticking can be reduced as compared with the case of forming with a metal.

Further, since the upper portion of the garbage storage container 12 is supported by the support 40 formed of a material having a smaller thermal expansion coefficient than the material of the garbage storage container 12 and attached to the container 11, the heating temperature is reduced. Garbage storage container supports 4
It is difficult to escape the hot air in the air layer 41 formed by the garbage storage container 12 and the container 11 due to being pressed against zero, thereby increasing the heat efficiency and drying faster.

Further, by setting the tips of the plurality of ribs 42 provided on the outer periphery of the side surface of the garbage container 12 so as to be in contact with the container 11, the heat convection in the air layer 41 is made smooth and the temperature is hardly increased. By transmitting the heat of the container 11 to the side of the garbage storage container 12 via the ribs 42, the heating efficiency of the garbage storage container 11 is further increased,
The rattle in the container 11 of the garbage storage container 12 can be suppressed.

Further, by making the garbage storage container 12 into a mortar-like shape and inclining the side surface, the garbage storage container 12 becomes more susceptible to heat from rising heat convection. It has the effect of collecting at the center of the bottom of the container 12, makes it easier to be crushed, and can increase the drying efficiency. Further, since the heater 30 is formed in a circular shape and the position of the heat generating portion is disposed below the side wall of the container 11, the side surface of the container 11 is located within the range of the heat of the heater which rises upward. As a result, the temperature distribution of the garbage storage container 12 becomes uniform, and the space can be effectively used for the agitating section provided at the center, and a compact structure can be obtained.

(Embodiment 2) Next, a second embodiment will be described with reference to FIG. The same parts as those in the above embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

At that time, since the outside air moves by the heat convection of the air layer 41, the outside air is heated during the passage, and even if the outside air is low in temperature, when the outside air enters the garbage storage container 12 through the second intake port 43, , High temperature. Therefore, warm air is sent into the garbage storage container 12, and drying is further promoted.

Since the outside air rises on the rising airflow, a suction force acts in addition to the suction means comprising the centrifugal fan 26 and the motor 27, and the load on the motor 27 is reduced.

Further, the second air layer 45 between the container 11 and the heat insulating case 33 further enhances the heat insulating effect. Further, the outside air from the air intake port 44 convects in the second air layer 45, The effect of transferring the heat at the bottom of the container 11 to the upper part of the side surface of the container 11 is achieved, the heating efficiency of the container 11 is increased, and the drying process can be performed with power saving.
