Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal apparatus for crushing kitchen garbage and the like. 2. Description of the Related Art A garbage disposal apparatus is mounted under a kitchen sink, crushes garbage such as garbage with a rotary blade and a fixed blade, and then flows the garbage together with sewage to a sewer through a drain. It is configured. This type of garbage disposal apparatus has been devised to prevent bad smell in order to treat perishable garbage. For example, a U-shaped trap is provided in a drainage channel for flowing crushed garbage from the garbage disposal device to block odors coming up from a sewer pipe. [0003] However, the conventional countermeasures against the odor of the kitchen garbage disposal apparatus can block the malodor coming up from the sewer pipe. However, there is a problem that the odor generated by the odor cannot be prevented. That is, after processing a relatively large amount of garbage having a high fiber content such as celery or corn skin, the fiber may be caught near the fixed blade or the discharge port of the garbage processing apparatus. Moreover, in the case of thin-skinned garbage such as onion skin, the garbage may adhere to the connecting pipe or the inner wall of the garbage disposal device. If such kitchen garbage is left, it will rot and produce a bad smell, which is not preferable for sanitation. In the past, aggressive measures to prevent such odors have not been made much. The present invention has been made to solve such a conventional problem, and has a function of cleaning garbage that has a function of cleaning garbage that is caught or adhered to a garbage disposal device or a communication pipe of a drainage channel. It is intended to provide a device. [0005] The kitchen waste treatment apparatus of the present invention is provided with a switching valve in the drainage channel, through which the backwash water for washing flows from the drainage channel side into the kitchen waste treatment device. Are connected. With the above arrangement, the switching valve is operated to introduce the backwash water from the backwash pipe into the kitchen waste treatment apparatus in a direction opposite to the normal flow of the wastewater. At the same time, the rotating plate of the garbage disposal device is rotated in the reverse direction to hold the garbage disposal device for a certain period of time, and the garbage attached to the inside of the garbage disposal device, the discharge port, and the connecting pipe is washed away. After a certain period of time, the three-way switching valve is switched again to stop backwash water from the backwash tube, and to discharge backwash water remaining in the garbage disposal apparatus and in the drainage channel and residual garbage. in this way,
By washing the inside of the garbage disposal equipment and the drainage channel with backwash water, not only the garbage caught on the discharge port and fixed blade,
Garbage attached to the inner wall of the garbage disposal device can be cleaned cleanly. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic view of an embodiment of a kitchen waste treatment apparatus according to the present invention, and FIG. 2 is a sectional view taken along line AA of FIG. In these figures, reference numeral 1 denotes a garbage disposal device provided on a bottom plate or the like of the sink 2, and inside the garbage disposal device 1, an electric motor (not shown), which is a rotary drive device, is hermetically stored.
A rotary plate 4 is fixed to a rotary shaft 3 of the electric motor, and a pair of rotary blades 5 is mounted on the rotary plate 4.
The garbage is crushed by the ring-shaped fixed blade 6 and the rotary blade 5 fitted on the outer peripheral portion of the garbage. [0008] The kitchen waste treatment apparatus 1 and a sewage pipe (not shown) communicate with each other through a drainage channel 7. That is, the connecting pipe 7A is connected to the side wall 8 of the kitchen waste treatment apparatus 1, and the drain pipe 7B is connected to the connecting pipe 7A. An electric three-way switching valve 9 is connected between the communication pipe 7A and the communication pipe 7B. However, the switching valve is not limited to the three-way switching valve 9. A backwash pipe 10 is connected to the three-way switching valve 9 and communicates with a water supply port for supplying tap water and the like. A check valve 11 is provided in the backwash pipe 10 so that sewage does not flow backward. The main body 1A of the kitchen waste disposal apparatus 1 and the three-way switching valve 9 are controlled by a control device 12. The control device 12 controls the kitchen waste processing apparatus main body 1 by sequence control.
A and the three-way switching valve 9 are controlled. 12A in FIG.
This is a switch of the control device 12. Next, the operation of the above configuration will be described. When using the garbage processing device 1, switch on the control device 12 is turned on.
The plug (not shown) of the switching valve 9 rotates to a position where the first port 9A and the second port 9B of the three-way switching valve 9 communicate simultaneously with the operation of the kitchen waste treatment apparatus 1. In the garbage processing apparatus 1, an electric motor is driven, and the garbage input together with the sewage from the input port is rotated by a rotating rotary blade 5.
And the fixed blade 6 crushed by the
A, flows through the three-way switching valve 9 to the drain pipe 7A. When processing garbage having a high fiber content such as celery or corn husk, as shown in FIG. 2, fibers 14 are disposed between the rotating plate 4 and the fixed blade 6 of the garbage processing apparatus main body 1A and near the discharge port 13. May be caught. In the case of thin-skinned garbage like onion skin, the garbage may adhere to the connecting pipe 7A, the inner wall of the garbage processing device 1, or the like. In such a case, a method of backwashing the kitchen waste disposal apparatus 1 will be described with reference to the flowchart of FIG. First, when "reverse" of the switch 12A of the control device 12 is pressed, the first port 9A of the three-way switching valve 9 is pressed.
The plug of the switching valve 9 rotates so that the and the third port 9C communicate with each other, and the backwash water is introduced into the kitchen waste treatment apparatus 1 from the backwash pipe 10 in a direction opposite to the flow of the sewage. At the same time, the rotating plate 4 of the kitchen waste treatment apparatus 1 is rotated in the reverse direction and held for a certain time,
The kitchen waste attached to the vicinity of the discharge port 13 and the connecting pipe 7A is washed off. After a certain period of time, the three-way switching valve 9 is switched again so that the first port 9A and the second port 9B can communicate with each other to stop backwash water and to communicate with the inside of the garbage disposal apparatus 1 and the communication. A large amount of backwash water and residual kitchen waste accumulated in the pipe 7A are discharged. By cleaning the inside of the garbage disposal apparatus 1 with the backwash water as described above, not only the discharge port 13 and the garbage 14 caught between the rotary plate 4 and the fixed blade 6 but also the inner wall of the garbage disposal apparatus 1 are provided. Garbage attached to the garbage can be cleaned cleanly. In the above embodiment, an electric valve is used as the three-way switching valve 9 and the control is performed by the control device 12. However, the present invention is not limited to such a configuration, and may be one that can be operated manually. Good. In such a manual case,
It is necessary to switch the three-way switching valve from time to time to wash the kitchen waste. As described above, according to the present invention, garbage such as fiber and skin remaining in the garbage disposal apparatus and the drainage channel can be eliminated by the above configuration. Therefore, it is possible to prevent the odor of the kitchen garbage from being spoiled, and to maintain the sanitary condition of the kitchen garbage disposal device and the sink for a long period of time.
