DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing apparatus for crushing kitchen garbage and the like.

[0002]

2. Description of the Related Art As shown in FIG.
Usually, it is attached below the sink 2 of the kitchen, and is configured to pulverize kitchen garbage such as garbage by the rotary blade 3 and the fixed blade 4 and then flow the garbage to the sewage pipe together with sewage. On the downstream side of the garbage disposal apparatus 1, sewage is treated by the sewage treatment equipment 5. In addition to sewage including crushed garbage, the sewage does not include garbage. Therefore, there is a problem when it is desired to efficiently treat sewage in the sewage treatment equipment 5. Therefore, a switching valve 7 is provided in the drainage pipe 6 on the downstream side of the garbage processing apparatus 1, and by operating the switching valve 7, when the wastewater discharged from the garbage processing apparatus 1 includes kitchen garbage, a high-load sewage treatment unit is provided. The sewage is allowed to flow into the sewage 8, and when the sewage discharged from the garbage treatment apparatus 1 does not include garbage, the sewage flows into the low-load sewage treatment section 9.

[0003]

However, in the case of the above-mentioned conventional garbage disposal apparatus 1, an electric valve, a solenoid valve, and a manual switching valve are required as the switching valve 7 provided in the drain pipe 6. In addition, the electric valve often takes a long time to switch the flow path, and the sewage may be appropriately selected and may not flow to the sewage treatment facility 5. In addition, although the solenoid valve can be switched in a short time, it needs to be energized during use time, which is not economical. Further, the manual switching valve must manually switch the switching valve before and after use of the kitchen waste treatment apparatus 1, and is not practical because it is inconvenient.

The present invention has been made to solve such a conventional problem, and has as its object to provide an easy-to-use kitchen waste disposal apparatus which has a short response time for channel switching, is economical, and is easy to use. And

[0005]

According to the present invention, there is provided a garbage disposal apparatus in which an upper drainage channel is provided in a processing chamber for crushing garbage, and a water pressure of sewage collected in the garbage disposal apparatus is provided in a main drainage channel near a falling chamber. A valve mechanism that opens when the pressure exceeds a certain value is provided.

[0006]

As described above, when the kitchen waste treatment apparatus is not used, the tap water flowing out of the faucet accumulates in the downflow chamber and the processing chamber while the valve mechanism of the main drainage channel is kept closed. Then, the water level rises and flows out of the upper drain pipe, and flows into the low-load sewage treatment section of the sewage treatment equipment, or is directly treated in the sewage pipe.

When the garbage disposal device is driven to rotate the rotary blade and the rotary plate, the waste water is collected in the device and swirls to rotate, and when the swirl becomes strong, the water pressure applied to the valve body of the valve mechanism increases. To open the valve, sewage flows out of the main drainage channel and flows into the high-load sewage treatment section of the sewage treatment facility.
Wastewater mixed with garbage in high concentration is treated.

[0008]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway front view of an embodiment of the kitchen waste disposal apparatus of the present invention, and FIG. 2 is a partially enlarged view of FIG. In FIG. 1, reference numeral 11 denotes a garbage disposal device provided on a bottom plate 12 of a sink or the like. An electric motor 14 which is an example of a rotary drive device is hermetically housed in a casing main body 13 of the garbage disposal device 11, and A rotary plate 17 having a pair of rotary blades 16 attached to the rotary shaft 15 of 14 is provided, and garbage is crushed by the ring-shaped fixed blade 18 fitted on the outer peripheral portion of the rotary plate 17 and the rotary blade 16. I have.
The upper part of the casing body 13 is covered with a hood 19,
Although not shown, it is fixed with bolts and nuts.

[0009] On the side wall of the casing body 13, the flow-down chamber 2 is provided.
The main drainage channel 21 communicating with 0 is connected. The main drainage channel 21 is connected to a connecting pipe 22 provided on a side wall of the downflow chamber 20.
And a drain pipe connected to the connecting pipe 22 (not shown). As shown in FIG. 2, in the connecting pipe 22, the valve closing state is normally maintained by the spring 24, and when the water pressure of the sewage in the garbage disposal device 11 increases with the rotation of the rotary blade and the rotary plate 17. A valve mechanism 25 that opens the valve is provided. Therefore, it is necessary to provide the valve mechanism 25 at a position where the water pressure of the sewage is applied with the rotation of the rotary blade and the rotary plate.

Further, an upper drainage channel 26 is connected to an upper portion of the hood 19 so that sewage collected in the processing chamber 27 flows out. Although not shown in FIG. 1, the upper drainage channel 26 communicates with a low-load sewage treatment unit of the sewage treatment equipment or is directly connected to a sewage pipe.

Next, the operation of the above configuration will be described. When the kitchen waste treatment apparatus 11 is not used, that is, when washing the dishes and vegetables while the electric motor 14 is not driven and the valve mechanism 25 of the main drain 21 is closed, the tap water flowing out of the faucet is
It accumulates in the downflow chamber 20 and the processing chamber 27. Then, the water level rises to H in FIG. 1 and flows out of the upper drainage channel 26, and flows into the low-load sewage treatment section of the sewage treatment equipment, or the sewage pipe. The valve body 28 of the valve mechanism 25 maintains the valve-closed state even if the water level rises to H by the spring 24.

A switch (not shown) of the kitchen waste disposal apparatus 11
, The electric motor 14 is driven, and the rotary plate 17 and the rotary blade 1
6 rotates, and a vortex is generated in the sewage in the kitchen waste treatment device 11,
When the vortex becomes stronger, the water pressure applied to the valve body 28 of the valve mechanism 25 rises so as to oppose the urging force of the spring 24, the valve body 28 opens, and dirty water flows out from the main drain 21. At this time, the water level in the processing chamber 27 falls to L, and the garbage introduced together with the sewage from the inlet is crushed by the rotating rotary blade 16 and the fixed blade 18. The crushed garbage flows into the high-load sewage treatment section of the sewage treatment facility through the main drainage channel 21, and sewage mixed with high-concentration garbage is treated.

In the above embodiment, the valve mechanism 25 uses a check valve in which the disc-shaped valve body 28 is closed by the spring 24, but the valve mechanism 25 of the present invention is not limited to a valve having such a structure. ,
Any type of valve can be used as long as it is opened by a constant water pressure.

[0014]

As described above, according to the present invention, the valve mechanism provided in the main drainage channel is opened and closed by the water pressure of the sewage in the garbage disposal apparatus, so that the response time for switching the flow path is short. In addition, since an electric switching valve is not required for the drain pipe, there is no need to energize, so that it is economical. Further, the valve mechanism opens and closes automatically, so that it is easy to use.
