[0002]

2. Description of the Related Art Conventionally, a technology relating to a garbage disposal apparatus for decomposing garbage using a microorganism or an enzyme as a treatment material has been known.
Many have been proposed and some have been put to practical use.
However, in such a conventional garbage processing apparatus, the odor of the garbage or the odor such as microorganisms is severe, and it is a serious problem to suppress or prevent the generation of such odor. Then, as a means for solving such a problem, for example, a technique described in Japanese Patent Application Laid-Open No. 10-43726 has been proposed. This technology is an apparatus having an intake path for taking in outside air into a processing chamber having a processing material for decomposing garbage, and an exhaust path for discharging air in the processing chamber to the outside, and circulating the air in the processing chamber. A dehumidifier is provided in the middle of the air circulation path so that the air flowing from the intake path is dehumidified by the air circulation path and exhausted from the exhaust path.

And the first to third processing tanks 20, 24,
Since the height of 29 is also the same and the entire upper surface is flat, the dehumidifier 40 and the crusher 13 can be placed and fixed in a stable state. Further, in the garbage disposal apparatus 1, since the temperature of the third processing tank 29 is set to a high temperature of about 100 to 130 degrees Celsius as described above, the temperature of the tray 34 discharged from the third opening 34 is reduced. 35
It is possible to kill a certain amount of bacteria (sterilization).

[0022]

As is clear from the above description of one embodiment of the present invention, in the present invention (the invention according to claim 1), the gas dehumidified by the dehumidifying device is passed through a pipe to form the gas. The gas flowing into the third processing tank is configured to flow into the third processing tank, and the gas flowing into the third processing tank flows into the second processing tank from the third processing tank, and flows again into the dehumidifier. like,
Since the air is circulated in the order of the dehumidifier, the third processing tank, and the second processing tank, the air in the garbage processing apparatus flows in the order of the dehumidifier, the third processing tank, and the second processing tank. , And is not exhausted to the outside from this circulation path, so that it is possible to further prevent the generation of offensive odor.

Further, the second invention (the invention according to claim 2)
Since a crushing device is provided between the charging port and the first processing tank, the processing of garbage by the processing material in the first processing tank and the second processing tank is extremely effective. In addition, the gas in the first processing tank can be effectively prevented from being discharged in the direction opposite to the direction in which the garbage is charged. In particular, in the present invention, since the gas is flowed from the second processing tank to the dehumidifying device, the gas in the first processing tank is moved to the second processing tank without moving to the crushing device. Because of the movement, combined with the mounting position of the crushing device, it is possible to further prevent the malodor from leaking out of the charging port.

In the third invention (the invention according to claim 3), the temperature in the first processing tank is the lowest, the temperature in the third processing tank is the highest, and the temperature in the second processing tank is lower. Since the third treatment tank forms the above-described air circulation path, it is not only effective for treating garbage but also can further prevent the generation of offensive odor. That is, when the first processing tank is set to the highest temperature, the gas inside easily rises, and there is a high possibility that a bad smell will leak from the inlet, and the second and third processing tanks If the temperature is low, the water content of the treated final product is also high, so the odor generated from the final product is also high, and the present invention can effectively prevent the generation of such a bad odor from the final product. it can.

Further, according to the fourth invention (the invention according to claim 4), the installation state of the dehumidifying device can be stabilized, and even when the crushing device is provided, it can be stably installed. , The size of the whole garbage disposal device can be made compact.
