FIELD OF INDUSTRIAL APPLICATION The present invention is applied to an apparatus for easily disposing of waste generated in kitchens, hospitals, etc. Garbage is currently disposed of in landfills or incinerated by local governments. Due to a lack of land for landfill, waste disposal has no choice but to rely on incineration, but incineration also poses issues such as hygiene issues during transportation and difficulty in locating an incinerator. The present invention relates to a device that reduces the weight and volume of waste at the place where it is generated, and makes it sanitary, and can solve this problem. The present invention can be used for waste disposal in homes, restaurants, grocery stores, etc.

A condensing section 13 surrounds the garbage container 1 in the storage section 3.
A drain pipe 14 is provided at the bottom of the storage section 3. Furthermore, the downstream side of the drain pipe 14 is divided into a steam exhaust pipe 15 and a drain pipe 16 . The air introduced into the cooling path 18 formed around the outer periphery of the storage section 3 by the blower 17 passes through the cooling path 18, the heat exchange wall 21 which is the outer wall of the garbage container 1, and the garbage container 1, and is mixed with steam and sucked. The steam is discharged outside through the steam exhaust pipe 15 and the catalyst 22 heated by the heater 20.

Garbage is thrown into the garbage container 1 through the door 9. The garbage container 1 can be taken in and taken out through a door 9 that is detachably provided inside the storage section 3. When the magnetron 10 oscillates microwaves in this state, the temperature of the dust 8 rises and generates water vapor. The temperature of the waste container 1 which is permeable to microwaves does not rise, but the temperature of the waste 8 which is permeable to microwaves tends to rise more than the central part where there is no heat dissipation. Therefore, water vapor is first generated in the center of the waste 8, and comes out from the surface while pushing out the free water due to thermal destruction of the surrounding waste. The pushed out free water passes around other garbage 8, flows down through the hole 2 at the bottom of the garbage container 1, and is discharged to the outside through the drain pipe 14.

Water vapor passes through the hole 2 of the garbage container 1 and enters the storage section 3.
Since the condensation section 13 outside the garbage container 1 is filled with the waste and is cooled by the air from the blower 17, it condenses on the inner wall of the storage section 3 and is discharged to the drain pipe 14. Since the condensed water of steam has undergone a distillation process, it has relatively little organic matter and flows down smoothly and is quickly discharged, so water droplets do not absorb microwaves and the bottom of the storage compartment 3 is kept relatively clean. It will be done.

The heat of condensation when the water vapor condenses and the latent heat of the condensed water heat the air in the cooling path 18 on the outer periphery of the storage section 3 via the heat exchange wall 21. Heat exchange performance is improved by providing unevenness on the heat exchange wall 21. In order to recover the heat of condensation, the cooling air flows in the opposite direction to the direction in which the condensed water flows, and first receives the sensible heat of the low-temperature condensed water located below the garbage container 1, and then receives the sensible heat of the high-temperature condensed water. Furthermore, it receives the heat of condensation from water vapor and becomes high-temperature air.

This high-temperature air makes a U-turn before the lid 9 and passes through the waste 8 in the waste container 1, thereby promoting the drying of the waste 8. This heated air is difficult to cool the garbage 8, so it accelerates drying, and the catalyst 20 supplies oxygen necessary for oxidizing the odor (as the drying progresses, the garbage 8
generates some amount of decomposition gas. This causes odor, but it is oxidized and rendered odorless by the catalyst 22, which is maintained in advance by the temperature detection unit 24 so as to reach the activation temperature by the heater 20). The moist air that has passed through the garbage is dehydrated again in the condensation space and discharged to the outside. The progress and completion of this drying is detected by means such as a decrease in the temperature of the temperature detection section 23, an increase in the temperature of the magnetron 10, or a change in the weight of the dust 8.

The garbage 8 shrinks when dry and accumulates at the bottom of the garbage container 1, but since it is dry, it will not rot even if stored as is, and can be repeatedly disposed of until the garbage container 1 is full.

[0021] The heat of the microwave is consumed as vapor latent heat of water, sensible heat of air, and heat radiated from the device. Therefore, when the blower 17 is controlled to substantially stop the amount of air blown and the waste 8 is heated and dried, almost no heat escapes to the outside of the container and efficiently becomes condensation heat of water vapor or latent heat of condensation heat. Focusing on this point, the present invention uses a bag as the garbage container and uses microwaves intermittently. That is, the detection unit 27 detects that the temperature of the storage chamber 3 or the waste container 1 has risen to a predetermined temperature due to the heat of condensation, the magnetron 10 is stopped, and at the same time, the amount of air blown by the blower 17 is increased to transfer the heat of condensation from the device to the waste. Transferred to container 8 and dried with warm air. The garbage 8 is cooled by latent heat while being dried by the dry warm air. When the temperature drops to a predetermined level, microwaves are irradiated and the amount of air blown is reduced again. By repeating this process, wasteful outflow of heat to the outside of the device is reduced. That is,
Since the storage section 3 or the garbage container 1 essentially functions as a heat storage material, there is no loss in heat conduction.

Furthermore, while microwaves tend to heat the dust from the center, warm air heats and dries only the outer surface, so drying can be speeded up by alternately operating the two.

Although microwaves are used as the heating means in this embodiment, the same effect can be obtained even if the method described in claim 1 is carried out using an infrared heater, an electric resistance wire heater, or the like.

Effects of the Invention As is clear from the above embodiments, a condensing section that cools water vapor evaporated from garbage with cooling air;
The cooling air has a blowing means and exhaust port for the cooling air, and a condensed water discharge means, and the cooling air is in contact with steam and condensed water through a heat exchange wall and flows in the opposite direction to the condensed water. This makes it possible to reuse the heat of condensation of water vapor and the latent heat of condensed water to dry waste.
