Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art As shown in FIG.
Usually, it is attached under the sink 2 of the kitchen, and is constructed so that kitchen waste such as garbage is crushed by the rotary blade 3 and the fixed blade 4, and then is sent to the sewer pipe together with the sewage. The sewage treatment equipment 5 treats sewage on the downstream side of the garbage treatment device 1. In addition to sewage containing crushed kitchen waste, this sewage does not include kitchen waste, for example, sewage containing only detergent. Therefore, when the sewage treatment facility 5 attempts to efficiently treat the sewage, a problem occurs. Therefore, a switching valve 7 is provided in the drain pipe 6 on the downstream side of the garbage treatment device 1, and by operating this switching valve 7, when the wastewater discharged from the garbage treatment device 1 contains garbage, the high load sewage treatment unit Sewage is made to flow into the waste water 8 and when the waste water discharged from the waste treatment apparatus 1 does not contain waste, it is made to flow into the low load waste water treatment unit 9.

[0003]

However, in the case of the above-mentioned conventional garbage treating 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. Moreover, it often takes time for the motor-operated valve to switch the flow path, and there is a case where the wastewater is properly selected and does not flow to the wastewater treatment facility 5. Further, the solenoid valve can be switched in a short time, but it needs to be energized during use, which is not economical. Further, the manual switching valve has to be manually switched before and after the garbage processing device 1 is used, which is inconvenient and impractical.

The present invention has been made in order to solve the above-mentioned conventional problems, and an object thereof is to provide a garbage disposal device which has a short response time for switching a flow path, is excellent in economic efficiency and is easy to use. I am trying.

[0005]

In the kitchen waste treating apparatus of the present invention, an upper drainage channel is provided in a processing chamber for crushing kitchen waste, and the main drainage channel near the downflow chamber is provided with a hydraulic pressure of waste water accumulated in the garbage processing apparatus. Is provided with a valve mechanism that opens when the pressure exceeds a certain value.

[0006]

As described above, when the garbage treatment device is not used as described above, the valve mechanism of the main drainage channel remains closed and tap water flowing out from the tap is collected in the downflow chamber and the treatment chamber. , The water level rises and flows out of the upper drainage pipe, and is either treated by the low-load sewage treatment section of the sewage treatment facility or treated directly, or directly into the sewer pipe.

When the garbage processing device is driven to rotate the rotary blade and the rotary plate, dirty water is accumulated in the device and swirls to rotate. When the swirl becomes strong, the water pressure applied to the valve body of the valve mechanism increases. In order to do so, the valve body opens, sewage flows out from the main drainage channel, and flows into the high-load sewage treatment section of the sewage treatment facility.
Wastewater with high concentration of garbage is treated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 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 garbage processing 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, and an electric motor 14 which is an example of a rotary drive device is hermetically housed inside a casing body 13 of the garbage disposal device 11. A rotary plate 17 having a pair of rotary blades 16 attached to the rotary shaft 15 of 14 is provided, and the kitchen blade is crushed by the rotary blade 16 and the ring-shaped fixed blade 18 fitted on the outer peripheral portion of the rotary plate 17. There is.
The upper part of the casing body 13 is covered with a hood 19,
Although not shown, it is fixed with bolts and nuts.

On the side wall of the casing body 13, the downflow chamber 2
The main drainage channel 21 communicating with 0 is connected. This main drainage channel 21 is provided with a connecting pipe 22 provided on the side wall of the flow-down chamber 20.
And a drain pipe (not shown) connected to the connecting pipe 22. As shown in FIG. 2, in the connecting pipe 22, the valve 24 is normally kept closed by the spring 24, and when the water pressure of the waste water in the garbage processing device 11 rises as the rotary blade and the rotary plate 17 rotate. A valve mechanism 25 for opening the valve is provided. Therefore, the valve mechanism 25 needs to be provided at a position where the water pressure of the dirty water is applied as the rotary blade and the rotary plate rotate.

Further, an upper drainage channel 26 is connected to the upper part of the hood 19 so that the dirty water accumulated in the processing chamber 27 flows out. Although not shown in FIG. 1, the upper drainage channel 26 communicates with the low-load wastewater treatment section of the wastewater treatment facility or is directly connected to the sewer pipe.

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

A switch (not shown) of the garbage processing device 11
The electric motor 14 is driven by turning on the rotary plate 17 and the rotary blade 1
6 rotates, swirl is generated in the wastewater in the garbage treatment device 11,
When this vortex becomes strong, the water pressure applied to the valve body 28 of the valve mechanism 25 rises enough to resist the urging force of the spring 24, the valve body 28 opens, and dirty water flows out from the main drainage channel 21. At this time, the water level in the processing chamber 27 drops to L, and the garbage that is thrown in with the dirty water from the throwing port is crushed by the rotating rotary blade 16 and the fixed blade 18. The crushed kitchen waste flows into the high load sewage treatment section of the sewage treatment facility through the main drainage channel 21, and the sewage mixed with the garbage in a high concentration 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 the 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 path is opened and closed by the water pressure of the waste water in the garbage processing device, so that the response time for switching the flow path is short. In addition, the drain pipe does not require an electric switching valve and does not need to be energized, which is economical. Further, the valve mechanism automatically opens and closes, which is convenient.
