DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust system in a garbage disposal apparatus for decomposing garbage using the power of microorganisms.

[0002]

2. Description of the Related Art A garbage disposal apparatus for decomposing (fermenting) garbage using microorganisms has been disclosed in Japanese Unexamined Patent Publication No. 5-2706.
No. 01 publication. In this garbage processing apparatus, a garbage processing tank is filled with a carrier such as wood chips called a biochip as a garbage processing material. The garbage is put into the garbage disposal tank through the garbage disposal port provided in the garbage disposal tank, and the garbage is collected by the microorganisms living in the garbage processing material while operating the stirring means and stirring with the stirring means. They are fermented and decomposed. After the garbage is put in, the garbage disposal port is covered and sealed so that the odor of the garbage disposal tank does not come out of the garbage entrance. However, when processing garbage in the garbage disposal tank, it is necessary to supply outside air to supply air to microorganisms living in the garbage processing material in order to treat garbage in the garbage processing tank. It is necessary to deodorize the odor generated in the processing tank by the deodorizing means and exhaust it to the outside. For this reason, conventionally, an outside air intake part for sucking outside air is provided separately from the above-mentioned garbage inlet, and an exhaust path for deodorizing odor generated in the garbage disposal tank and exhausting it to the outside. And an exhaust fan is provided in the exhaust path, and by rotating the exhaust fan, an air flow is formed from an outside air intake section to a garbage disposal tank to an exhaust path, and fresh air is supplied into the garbage disposal tank. At the same time, the odor generated in the garbage disposal tank is exhausted to the outside through an exhaust path. However, in this case, the odor flows into the exhaust path by the exhaust fan,
In deodorizing by the deodorizing means provided in the exhaust path, if the air volume of the exhaust fan is large, the deodorizing effect cannot be sufficiently exerted by the deodorizing means, so that the air volume of the exhaust fan cannot be increased. There are restrictions. Since the air volume of the exhaust fan cannot be increased in this way, there is a problem in that, when the garbage is opened and the garbage is introduced, the odor generated in the garbage disposal tank flows out into the room. Was. Furthermore, although the exhaust gas flowing through the exhaust passage is deodorized by the deodorizing means, the exhaust gas may be exhausted to the outside without sufficient deodorization. In this case, there is a problem that odor is emitted at the outlet of the exhaust passage.

[0003] Therefore, the present inventor, in the process of reaching the present invention,
Consider a garbage disposal apparatus that supplies dilution air to the vicinity of the outlet of the exhaust path 5 to dilute the exhaust air and discharge the diluted air to the outside. Incorporating the garbage disposal apparatus A into a kitchen cabinet 11 such as a sink. Thought. This is shown in FIG. 8, the garbage inlet 2 is formed in the top plate of the kitchen cabinet 11, and the garbage is thrown in when the lid 3 'is opened. There is a problem that the odor in the processing tank 1 flows out of the kitchen waste inlet 2 into the kitchen. That is, although the garbage generated in the garbage processing tank 1 is exhausted by the exhaust fan 6, the capacity of the exhaust fan 6 cannot be increased so much (that is, if the capacity of the exhaust fan 6 is increased, Since the deodorizing performance of the deodorizing means is reduced, the capacity of the exhaust fan 6 cannot be increased so much. Therefore, when the lid 3 'is opened and the garbage inlet 2 is opened, the garbage disposal tank 1 Some of the odor generated inside flows out of the inlet 2. In the related art, the dilution fan 7 partially removes the odor generated in the garbage disposal tank 1 into the garbage inlet 2.
It does not help prevent spills.

Conventionally, it is necessary to separately form an opening serving as an outside air intake unit 50 and an opening serving as a dilution air supply unit 51 for supplying air to the kitchen waste treatment tank 1 in the kitchen cabinet 11. However, there was a problem that the appearance also deteriorated. Further, at the time of a power failure, the odor flows into the room unless both the opening serving as the outside air suction unit and the opening serving as the dilution air supply unit 51 are sealed, but the opening serving as the outside air suction unit 50 and the dilution air supply It takes time and effort for the user to seal the opening serving as the part 51.
