[0002]

2. Description of the Related Art As an example of this type of garbage processing device,
As shown in FIG. 5, there is a product in which raw garbage is heated and dried in the processing container 1 to reduce the weight and weight, thereby facilitating the handling of storage and transportation. There, the outer circumference of the processing container 1 is covered with an outer box 2. The outer box 2 is composed of a box main body 3 that covers the peripheral side and the bottom of the processing container 1, and a lid 5 above the box main body 3. Then, the blower fan 26 for taking in the outside air into the processing container 1 is built in the fan case 27 provided in the lid 5 corresponding to the upper inside of the processing container 1, and the outside air is blown by the blowing fan 26 and the box body 3. The air is sucked into the heat insulating space S in the lid 5 from the gap 28 provided therebetween, passed through the fan case 27 through the through hole 29 around the axis of the blower fan 26, and is supplied from the air supply port 30 provided in the fan case 27 to the processing container. Blow into 1,
Therefore, the exhaust of the gas generated in the processing container 1 is promoted.

[0003]

However, the outer box 2 is heated to a high temperature by the steam heat generated during the heating and drying of the garbage in the processing container 1, and particularly the lid 5 that closes directly above the processing container 1 has the steam heat. It was easy to get very hot. So, for example,
When the lid 5 is provided with an operation unit 31 such as a power switch, the operation unit 31 is heated and makes the user feel uneasy, and when another object is placed on the lid 5, heat damage is likely to occur, and the box When the main body 3 is made of a metal plate or the like having excellent weather resistance such as an iron plate or the like, there arises a problem that the surface is easily heated. Such a problem is that a heat insulating space S is formed between the processing container 1 and the box body 3 as a heat insulating measure, and the heat insulating space S is also provided inside the lid 5.
However, it was not completely satisfactory. That is, the heat insulating space S in the lid 5
Is in communication with the inside of the processing container 1 through the through hole 29 and the air supply port 30, and therefore the vapor in the processing container 1 flows backward when the driving of the blower fan 26 is stopped. However, there is a drawback that the odor inside the processing container 1 leaks out through the gap 28 for sucking the outside air.

An object of the present invention is to solve the above problems, and an object of the present invention is to provide a garbage disposal device capable of improving the heat insulating effect between the outer box and the processing container and preventing odor leakage.

[0005]

According to the present invention, as shown in the drawing, a processing container 1 which receives raw garbage and heats and dries it is housed inside an outer box 2 and the outside air is sent into the processing container 1. In the kitchen waste treatment device provided with the air supply line 9,
A heat insulating space S is provided between the processing container 1 and the outer box 2, and
In addition to being provided in a state of not communicating with the inside thereof and independently of the air supply conduit 9, the outside air inlet port 14 and the outlet port 15 are opened in the outer box 2 so as to communicate with the heat insulating space S,
The heat insulating space S is provided with a blower 16 for sucking the outside air from the outside air inlet 14 and discharging the outside air toward the outlet 15.

[0006]

The vapor in the processing container 1 does not flow back into the heat insulating space S which is provided in a state of not communicating with the interiors of the processing container 1 and the air supply conduit 9. Therefore, it is possible to prevent the odor from leaking to the outside from the outside air inlet 14 of the heat insulating space S. In the heat insulating space S, the air flow of the fresh and dry outside air can be always promoted by the air blowing means 16, and the heat insulating effect between the processing container 1 and the outer box 2 is improved.
