DISINTEGRATION END DETECTOR FOR DISPOSER, CONTROLLER FOR DISPOSER AND METHOD OF CONTROLLING DISPOSER

摘要

PROBLEM TO BE SOLVED: To provide a disintegration end detector for disposer which is capable of exactly detecting the disintegration end of garbage and can save of electricity and water, and a controller. SOLUTION: The disintegration end detector 100 is a disintegration end detector for a disposer to disintegrate the garbage by a disintegrating mechanism 4 interlocked with a drive motor 3 and has a current phase detecting circuit 110 which detects the phase of the current supplied to the drive motor 3, a voltage phase detecting circuit 120 which detects the voltage phase of the AC voltage of a commercial power source and a multiplier circuit 130 which calculates the phase difference of the current phase detected by the current phase detecting circuit and the voltage phase detected by the voltage phase detecting circuit. The phase difference calculated by the multiplier circuit and the preset reference value of the current at the disintegration end of the drive motor 3 are compared and the disintegration end is decided when the phase difference exceeds the reference value.
