SOLUTION: A detecting switch 5 which close a circuit when detected that the bulb 4 of a feed pipe 3 is opened to the extent that a prescribed quantity of water supply can be obtained, is provided in the feed pipe 3 supplying water to a sink 1 equipped with a disposer 2. The motor 23 of the disposer 2 and the detecting switch 5 are connected with a lead wire 6. Thus, the motor 23 is connected to a power source in the state where the detecting switch and the driving switch are in-series.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposer operating device for pouring and crushing kitchen garbage with water.

[0002]

2. Description of the Related Art Garbage is crushed by throwing garbage together with water into a crushing room of a disposer attached to a sink of a sink, receiving the garbage on a rotating plate of the crushing room, and rotating the rotating plate with a motor. Crushed and cut between a fixed blade facing the periphery of the rotating plate and discharged to the discharge pipe through the discharge chamber below the rotating plate. Either open the valve and start the motor while pouring water to rotate the rotating plate, or open the water valve in advance and start the motor while pouring water and put the garbage in, either operation method is performed The former method is mainly used for treating small quantities of garbage, and in the case of a cafeteria or the like where a large amount of garbage is generated, a method of continuously putting garbage in a state of flowing water is used.

[0003]

As described above, in a disposer in which garbage is poured together with water and crushing treatment is performed, a sufficient amount of water is supplied by opening a water valve attached to the sink before starting the motor of the disposer. Although it is necessary to put it in a state, often when putting in garbage and immediately starting operation, or when intermittently processing even when processing large quantities, once the disposer is stopped and the valve is closed, When throwing garbage, operation may start before opening the valve, and if the rotating plate is operated without adding enough water, crushing will not be performed efficiently and not only will the processing capacity decrease, Since the rotating plate is locked or the crushed garbage is not smoothly discharged to the discharge chamber and drainage pipe, the garbage that has fallen below the rotating plate may flow out. Which may cause the discharge chamber and pipes clogged with no. When such an accident occurs, it is necessary to disassemble and repair the disposer, which is not only troublesome but also causes a large loss such as a reduction in the amount of processing. The present invention provides an operating device that enables a disposer to be operated only in a water supply state, prevents accidents due to inadvertent mistakes, and enables efficient disposal of kitchen waste.

[0004]

For this reason, in a disposer which is attached to a sink and is used for pouring kitchen garbage together with water and crushing, a valve of a water supply pipe for supplying water to the sink is opened to a predetermined water supply amount. A detection switch, for example, a flow rate switch or a pressure switch, for detecting and closing the circuit is provided, and an operation switch for operating the motor of the disposer and the detection switch are connected in series to a power supply.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A sink for mounting kitchen waste with a disposer attached thereto, a water supply pipe for supplying water to the sink, and a valve for the water supply pipe are provided, and the flow rate in the water supply pipe reaches a predetermined amount of water supplied to the water supply pipe. A flow switch that sometimes closes,
Alternatively, a detection switch such as a pressure switch that closes when the pressure in the water supply pipe due to water supply reaches a pressure corresponding to a predetermined water supply amount is provided, and a connection cord drawn from the detection switch is connected to a control panel of the disposer. Then, the detection switch and the operation switch of the motor are connected in series to the power supply.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment shown in FIG. 1 and 2, reference numeral 1 denotes a sink, and 2 denotes a disposer attached to a sink of the sink. A rotating plate 22 provided in a crushing chamber 21 is rotated by a motor 23 to crush the garbage put on the rotating plate 22. After processing, the outer periphery of the rotating plate and the fixed blade 2
4 to the discharge chamber below the rotating plate, and the discharge pipe 2
Discharge to 5 Reference numeral 3 denotes a water supply pipe for supplying water to the sink 1, 4 denotes a valve of the water supply pipe 4, and 5 denotes a detection switch connected to the water supply pipe 3. In this embodiment, a flow rate switch is used.
6 is a lead wire connected to the motor 23 of the disposer 2, 7 is a connection cord drawn from a detection switch (flow rate switch) 5, 8 is an operation switch provided on the operation panel 9, and 10 is a power supply.

When the valve 4 of the water supply pipe 3 is opened, the flow rate in the water supply pipe 3 increases, and when a predetermined flow rate is reached, the flow switch 5 is closed. Therefore, when a predetermined amount of water is not supplied into the disposer 2, the detection switch 5 is open, and the operation is performed without opening the valve 4 before or after throwing the garbage from the sink 1 into the crushing chamber 21. Even if the switch 8 is closed, the motor 23 does not start and the crushing process is not performed. When valve 4 is opened and sufficient water is supplied,
The flow switch 5 is closed and the disposer motor 23 is closed.
Is activated and the kitchen waste is processed with sufficient water. It should be noted that the motor 23 does not start unless the operation switch 8 is closed even if water is supplied to the sink when the kitchen waste is not processed.

FIG. 3 shows an embodiment in which a pressure switch is connected to the water supply pipe 3 as a detection switch 5 instead of the flow rate switch.
1 are denoted by the same reference numerals, and when the valve 4 is opened to change the water pressure of the water supply pipe 3 and the water pressure of the branch pipe 11 decreases to a predetermined value, the detection switch (pressure switch) 5 is closed. Then, the motor of the disposer 2 can be started and operates in the same manner as the embodiment of FIG.

[0009]

As described above, the present invention is connected to a water supply pipe for supplying water to a sink having a disposer, and detects a state in which the valve of the water supply pipe is opened to obtain a predetermined water supply amount, and closes the circuit. Since a detection switch is provided and this detection switch is connected to the power supply in series with the operation switch of the disposer, it is possible to prevent processing without supplying sufficient water to the disposer when processing garbage,
Garbage can always be disposed of in good condition, protecting the disposer and eliminating clogging of the garbage. In a kitchen or the like, the hands are often wet, and it is desirable to use a waterproof operation switch. However, as an operation procedure, usually, after the operation switch is turned on (ON), water is poured into a sink to dispose of the kitchen waste. When the process is completed, the water is stopped and the power switch is turned off (OFF). Therefore, when the operation switch is operated, the valve is closed, and the detection switch is opened and the electric circuit of the motor is opened. Therefore, even if the operation switch is operated with wet hands, there is no danger of electric shock and there is an effect that safety can be improved even if the switch is not a waterproof switch.

Since the operation switch is open when the garbage is not disposed, even if the valve is opened and the detection switch is closed, it is possible to keep the disposer from being activated. Also, leave the operation switch closed,
Or, if omitted, when the water supply is stopped, the operation of the disposer is stopped, and the operation is performed by opening the valve to a predetermined amount, so that the automatic operation of the disposer by operating the valve can be performed, especially for intermittent processing. In such cases, efficient processing can be performed.
