The method for controlling the household kitchen waste treatment comprises the following steps:
when the motor is started, the remote controller sends a signal, and the CPU U1 realizes the starting and running of the motor by controlling the bidirectional thyristor switches Q1Q2 and K1 to realize the on-off of the motor auxiliary winding SW and the on-off of the motor main winding RW.
When the double-pole double-throw relay K1 is started, the state of the double-pole double-throw relay K1 is replaced by the CPU U1 according to the recorded state of the last time K1, after 200-300 milliseconds, the bidirectional thyristor switch Q1 and the bidirectional thyristor switch Q2 are switched on, the bidirectional thyristor switch Q2 is switched off after the starting is finished, and the state of the double-pole double-throw relay K1 is recorded by the CPU U1, so that the automatic reverse rotation of power-on can be carried out when the double-pole double-throw relay K1 is started each time: the CPU U1 records the state of the double-pole double-throw relay K1 after each start of the motor, and realizes the reversing start of the motor by changing the state of the double-pole double-throw relay K1 when the motor is started next time.
After the start is finished, when the motor normally operates, the CPU U1 detects the voltage of the motor auxiliary winding SW, if the voltage Vsw of the motor auxiliary winding SW is lower than a set threshold value, the motor state is judged to be locked, the bidirectional thyristor switch Q1 and the bidirectional thyristor switch Q2 are cut off through the CPU U1, the motor is stopped, after 200-300 milliseconds of delay after the state of the CPU U1 is switched, the bidirectional thyristor switch Q1 and the bidirectional thyristor switch Q2 are switched on, the motor reversing restart is realized, after the start is finished, the bidirectional thyristor switch Q2 is cut off again, and finally the CPU U1 records the state of the double-pole double-throw relay K1. If the motor is not locked, the CPU U1 can repeatedly detect the voltage of the motor auxiliary winding SW and repeat the judgment.
And, the number of times of blocking is also protected, wherein, the threshold value of the number of times of blocking is set by the CPU U1, when the number of times of blocking the motor of the processor exceeds the set threshold value, the CPU U1 controls to cut off the power supply of the motors of the two-way thyristor switch Q1 and the two-way thyristor switch Q2 until the remote control receives the working signal, and then the motor is restarted.
