It is determined whether or not it has elapsed (step S8), the signal to open the solenoid valve is stopped (step S9), the solenoid valve 70 is closed, and the water purging is stopped.

After the garbage has been pulverized, the drive motor 3 is stopped after a lapse of a predetermined time, and then, after a lapse of a predetermined time, the solenoid valve 70 is closed to stop water supply. The crushing chamber 24 can be cleaned, and when the eye plate 5A and the water blocking lid 5B are removed, the crushed garbage does not remain inside the crushed garbage. Can keep the inside clean.

In the above-described embodiment, the user sets the crushing time of the garbage by, for example, the amount of garbage, and outputs the crushing end signal after the set time has elapsed. However, the present invention is not limited to this. For example, the power of the drive motor 3 for driving the crushing mechanism 4 is detected, the power at the time of crushing is compared with the power at the end of crushing, and the end of crushing is detected and the drive is performed. The motor may be configured to stop. Furthermore, the phase difference between the current phase and the voltage phase when the drive motor is driven is detected, and when the load is reduced at the end of grinding, it is detected that the phase difference is reduced, so that the end of grinding is determined. It may be.

In addition, raw garbage is introduced from the sink inlet 10b, the mixing faucet 50 is opened, and water is supplied at a predetermined flow rate.
The driving motor 3 is manually driven to operate the crushing mechanism 4,
Assuming the time required for the user to crush from the amount of garbage,
The drive motor 3 may be manually stopped after a predetermined time has elapsed, and then the mixing faucet 50 may be closed to stop water supply. In this case as well, the water is stored in the perforated plate 5A by supplying the water at a predetermined flow rate, and the stored water W closes the inlet 10b, so that noise and odor from the inside of the disposer D can be prevented from leaking.
