For example, in addition to the detection unit, the conversion unit, the comparison unit, the amplifier, and the like, an actuator that collectively includes a setting unit provided in the controller 7 and a timer may be used. Further, the controller may be provided with a converter, a comparator, an amplifier, etc., all at once.

The operation of this embodiment will be described below with reference to the flow chart shown in FIG. First, the opening degree of the valve body 5a is set in advance by the setting unit 7a, and the operation timing of the disposer body 1 and the automatic valve 5 is set in the timer 7b.

Next, when garbage is packed in the disposer body 1 and the lid 2 is closed, the lid switch 2b is turned on, the timer 7b is activated, and the relays T1, T2 and T3 are turned on. This opens the contact T1-1 and the contact T
21 is closed, contact T22 is closed, contact T23 is opened, contact T31
Is closed, and the contact T32 is opened. First, in the setting unit 7a of the controller 7, the resistance value, for example, the valve opening 50
%, Which is 75Ω, is set. And this setting unit 7
The converter 52 converts the resistance value set by a into a voltage value (setting voltage), the potentiometer 51 detects the opening of the valve body 5a as a resistance value, and the converter 53 converts the resistance value into a voltage value ( (Measured voltage) and the comparison unit 54 calculates the deviation between the set voltage and the measured voltage.

A is fully closed, and the supply of water to the disposer body 1 is terminated (water supply after stopping the disposer body). Here, since the check valve 6 is installed in the water supply pipe 20, the water that has entered the disposer body 1 does not flow back.

When the lid 2 is opened in the middle, the timer 7
b turns off the relay T2, and causes the motor 12 of the disposer main body 1 to stop urgently.

Therefore, simply by filling the inside of the disposer body 1 with the garbage and closing the lid 2, a fixed amount of water is supplied to the disposer body 1 for a predetermined time to crush the garbage without clogging the drain pipe. be able to. Further, since the disposer body 1 does not operate unless the lid body 2 is closed, it is possible to prevent the disposer body 1 from being broken by dropping a spoon or the like into the disposer body 1, and to prevent accidental insertion of hands. It prevents things and is safe.

Here, when the external switch 8 is used, the opening / closing of the lid 2 and the operation of the disposer body 1 become irrelevant, and the external switch 8 is turned on even when the lid 2 is open.
By doing so, water supply before starting the disposer body and starting of the disposer body 1 can be performed. Also,
By turning off the external switch 8, the operation of the disposer body 1 can be stopped, and water can be supplied after the disposer body is stopped.

In this case, since the disposer main body 1 can be operated with the lid 2 open, it is possible to grind the garbage that is successively produced by washing dishes and the like.

Next, an embodiment in which a flow rate sensor is used for the detecting portion will be described. As shown in FIG. 7, the flow rate sensor 9 is installed in the water supply pipe 20, and the flow rate sensor 9 and the controller 37 are connected. Controller 3 in this case
7 is provided with a timer, a flow rate setting unit, a conversion unit, a comparison unit, an amplifier and the like, and the detection signal of the flow rate sensor 9 and the output signal of the set flow rate in the flow rate setting unit are converted into voltage levels in the conversion unit. The converted voltage values are converted and compared by a comparison unit to calculate a deviation voltage. The deviation voltage is amplified by an amplifier and added to the motor of the actuator 35b to adjust the opening of the valve body 35a. The flow rate measured by and the flow rate set in the flow rate setting unit are matched. When changing the amount of water supply before and after stopping the disposer body, it is preferable to set the flow rate at each time in advance in the flow rate setting unit and switch using a timer.

The flow rate sensor 9 is appropriately selected from those whose resistance value changes depending on the flow rate, those whose voltage value changes, those whose current value changes, and those whose pulse number changes.
