Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal apparatus capable of decomposing organic substances (garbage and cooking effluent, etc.) mainly generated in a home kitchen by microorganisms and flowing the treated water through a sewer pipe. It is about.

[0002]

2. Description of the Related Art FIG. 8 is a block diagram of a conventional garbage processing apparatus. In FIG. 8, reference numeral 1 denotes a sink, and a crushing means 3 is installed at a drain port 2 provided at the bottom thereof.
The crushing means 3 and the garbage disposal unit 4 are connected by a pipe 5. The garbage disposal unit 4 includes a cylindrical decomposition tank 6, a cylindrical processing tank 7, and a water tank 8. The processing tank 7 is located inside the decomposition tank 6, and the inside of the processing tank 7 and the crushing means 3 are connected by a pipe 5. The outer peripheral portions (cylindrical peripheral wall portions) 9 and 10 of the decomposition tank 6 and the processing tank 7 are each composed of a member having a large number of small holes in the form of a wire mesh, and are integrally rotated by the rotation driving means 11. . The water tank 8 is connected to a drain 13. The decomposition tank 6 is filled with a required amount of a filter medium 14 for inhabiting microorganisms.

The operation and operation of the garbage disposal apparatus configured as described above will be described below. First, the garbage generated in the kitchen is put into the crushing means 3, and the power is turned on to pour water while crushing the garbage. Enter tank 7. The crushed garbage is rotated by the rotation driving means 11.
It is stirred in the processing tank 7.

[0004] Then, it passes through the wire mesh of the outer peripheral portion 9 and enters the inside of the decomposition tank 6. The garbage that has entered the decomposition tank 6 is
It is decomposed by microorganisms attached to the water tank and accumulates in the water tank 8. Then, the water is transported again to the decomposition tank 6 by a pump (not shown), and is completely decomposed while repeating this process. The purified water falls into the water tank 8 and overflows, and is drained to the sewer through the sewer pipe 13. By rotating the decomposition tank 6 by the rotation driving means 11, oxygen required for microbial decomposition is effectively supplied to the microorganisms.

[0005]

However, in such a method, when the decomposition tank 6 and the processing tank 7 are rotated, the garbage in the processing tank 7 is unevenly distributed, for example, in a lump. The contact area of the microorganisms is reduced, and no oxygen is supplied to the central part of the garbage, so that it cannot be said that the microorganisms are efficiently decomposed. Therefore, garbage easily accumulates in the processing tank 7 and maintenance such as periodically removing the garbage collected in the processing tank 7 is required.

The present invention has been made to solve the above problems of the garbage disposal apparatus, and to improve the decomposition performance of the garbage disposal apparatus to provide a garbage disposal apparatus.
