Next, the configuration of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a configuration of a garbage disposal apparatus attached to a sink.
The garbage disposal device 31 is disposed below the sink 32 and is connected to a drain outlet of the sink 32. In the garbage disposal device 31, a separation unit 33 is disposed immediately below the drain outlet of the sink 32, and a drying unit 34 is configured below the solid liquid separation unit 33. A volume reducing unit 35 is connected, and a storage unit 36 is configured in the volume reducing unit 35.

  The separation unit 33 separates garbage and waste water, holds the garbage in the separation unit 33, and discharges the liquid to the drain pipe 3. The separation unit 33 is configured to be able to hold a certain amount of garbage and discharge the introduced waste water to the drain pipe 3 even when the garbage is stored. For this reason, garbage is exposed to the waste water introduced into the separation part 33, and water-soluble components, such as salt contained in garbage, can be washed away by waste water.

The drying unit 34 introduces the garbage stored in the separation unit 33 and dries it. Since it becomes possible to introduce into the drying unit 34 the garbage from which water-soluble components such as salt are reduced in the separation unit 33, the energy required for drying the garbage can be reduced.
The volume reducing unit 35 compresses and reduces the volume of garbage dried in the drying unit 34. The storage unit 36 stores the waste compressed in the volume reduction unit 35.
In this manner, by disposing the separation unit 33, the drying unit 34, the volume reduction unit 35, and the storage unit 36, the garbage can be discharged together with the waste water from the sink 32 and can be introduced into the garbage processing device 31. . And a liquid and garbage are isolate | separated, the water-soluble component of garbage can be decreased, and it can dry and can reduce and store.

The drying unit 34 includes a heater 11, a fan 12, and the like. The volume reducing unit 35 is configured by the screw 15, the screw driving device 6, and the like, and the storage unit 36 is configured by the drawer 16 and the support 24.

The processing device 31 is mainly configured by mounting various devices on the frame 20, and the frame 20 is configured by connecting an upper frame 20a and a lower frame 20b. The rubber packing 1 is attached to the upper end of the frame 20 to connect the drain port of the sink 32 and the garbage disposal device 31.
In the separation part 33, the net body 8 that separates garbage and waste water is provided in the upper frame 20a, and the drain pipe 3 is connected to the upper frame 20. The net 8 has an opening on the side surface, and the bottom is closed. The net body 8 is provided with an arm 2 for rotating the net body 8. The arm 2 is rotatably supported at both ends by a pivotal support 5 and a net drive unit 4, and is configured to rotate with the net 8 by the net drive unit 4. By rotating the net body 8 in the upper frame 20 a by the net body driving device 4, the garbage retained in the net body 8 is discharged to the drying unit 34.
Note that a deceleration motor can be used as the mesh body driving device 4.

A seal ring 7 mounted in the frame 20 is disposed below the mesh body 8, and the drying unit 34 is isolated from the separation unit 33 by the bottom of the mesh body 8 and the seal ring 7. .
