Abstract

PROBLEM TO BE SOLVED: To provide a small sized garbage treating machine which can be used safely in a kitchen or its vicinity. SOLUTION: The machine is provided with a garbage receiving container 12, a container 11 for drying into which the container 12 is inserted, and a heater 30 for heating the container 11, an air layer 41 is formed between the container 12 and the container 11, the thickness of the air layer 41 is increased near the heater 30 and decreased with the distance from the heater 30, so that the container 12 can be heated almost uniformly to demonstrate a heating capacity equivalent to that in a conventional method of hot-air introduction even at relatively low temperatures, and garbage can be dried in a short time. Since the temperature of the container 12 is controlled below the heat distortion temperature of a heat resistant resin even when the temperature of the heater 30 is increased, the raw material can be selected freely as compared with a method in which a garbage receiving container is heated directly.

From the discharge port 20 to the deodorizing device 22 and discharged outside.

The operation of the 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 drying container 11 heated by the heater 30 transfers heat to the garbage storage container 12 from all around, and the temperature in the garbage storage container 12 rises to heat the garbage. Steam is generated from the heated garbage and is discharged from the discharge port 20 at the top of the garbage storage container 12.

The discharged steam is supplied to the fan 26 and the motor 2
, And the suction filter 3
9. After the odor is removed by the deodorizing device 22 through the exhaust hose 21, it is discharged to the outside. Therefore, there is no unpleasant odor during drying, and the crushed and dried garbage is stored in the garbage storage container 1.
Although it remains in 2, it has a reduced bulk, is easily discarded, and is dried and has a reduced water activity, so that it does not rot or generate mold. Therefore, until the garbage storage container 12 is full, 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, lose weight, and is 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 drying container 11 is set so as to gradually narrow upward. Therefore, the temperature of the bottom of the drying container 11 near the heater 30 increases (about 250 ° C.), but the bottom has a large gap between the garbage storage container 12 and the drying container 11, so that the garbage storage container 12 Is kept low (about 130 ° C.).

On the other hand, as the side of the drying container 11 goes upward, the heat of the heater 30 is hardly transmitted, and the temperature decreases (about 160 ° C.).
Is small, the heat transfer to the garbage storage container 12 is improved, and the temperature becomes almost the same as the bottom surface (about 130 ° C.).

Therefore, the garbage storage container 12 is heated to a substantially uniform temperature in the vertical direction, so that the garbage storage container 12 exhibits the same heating capacity as the conventional method of blowing in hot air even at a relatively low temperature, and reduces 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.

Since the upper portion of the garbage container 12 is supported by the support 40 formed of a material having a smaller thermal expansion coefficient than the material of the garbage container 12 and attached to the drying container 11, As the heating temperature rises, the garbage storage container is pressed against the support 40, and the hot air in the air layer 41 formed between the garbage storage container 12 and the drying container 11 becomes more difficult to escape, resulting in higher thermal efficiency and faster drying. Become.

Further, by setting the ends of the plurality of ribs 42 provided on the outer periphery of the side surface of the garbage storage container 12 so as to be in contact with the drying container 11, the heat convection in the air layer 41 is made smooth and the temperature is reduced. Garbage storage container 12 that is difficult to rise
By transmitting the heat of the drying container 11 to the side surface via the ribs 42, the heating efficiency of the garbage storage container 11 is further increased, and rattling in the drying container 11 of the garbage storage container 12 can be suppressed. it can.

By making the garbage storage container 12 into a mortar-like shape and inclining the sides, heat is easily received from rising heat convection, heating efficiency is increased, and the garbage storage has a stirring section. 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 drying container 11, the side surface of the drying container 11 is positioned within the range of the heat of the heater rising upward.

The outside air flowing in from the air intake 44 enters the air layer 41 via the suction port 35, and passes around from below to above. 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, suction force acts in addition to the capacity of the suction means including 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 drying container 11 and the heat insulating case 33 further enhances the heat insulating effect, and the outside air from the air intake 44 convects also in the second air layer 45. This has the effect of transmitting the heat at the bottom of the drying container 11 to the upper side surface of the drying container 11, increasing the heating efficiency of the drying container 11 and performing the drying process with low power consumption.

Preferably, the second heater 51 is provided above in consideration of the temperature distribution in the height direction of the garbage storage container 12.

The operation of the above configuration is as follows.
By the suction force of the centrifugal fan 26, the air in the lid 24 is taken into the space surrounded by the garbage storage container 12 and the lid 24 from the intake port 50. The side wall of the garbage container 12 is heated by the second heater 51 wound around the outer periphery of the drying container 11. The fan 46 provided on the lower surface of the lid 24 stirs the air in the garbage storage container 12, and at this time, heats the side wall of the garbage storage container 12 to increase the temperature of the air in the garbage storage container 12. By circulating high-temperature air, the drying speed of garbage can be increased.

Further, a fan 46 provided on the lower surface of the lid 24
This stirs the air in the garbage storage container 12 to remove the heat from the bottom surface to make the temperature in the garbage storage container 12 uniform and to scatter the steam on the surface of the garbage to promote the generation of steam. The drying speed can be increased.
