The invention also provides a kitchen waste disposer control method, which is applied to the kitchen waste disposer and comprises the following steps: step S11 and step S12.

In step S11, a motor rotation torque of the drive motor in a rotating state is detected;

when the driving motor is started, the driving motor rotates at an initial speed and in a first rotating direction such as a counterclockwise direction, and the rotating torque of the motor is monitored in real time under the rotating state of the driving motor. The motor rotating torque is different when the food quantity is more, the motor rotating torque is larger, and the motor rotating torque is smaller when the food quantity is more.

In step S12, the rotational speed and/or rotational direction of the drive motor is controlled based on the monitored motor rotational torque.

Under different rotational speeds, the quartering hammer swing striking dynamics differs, can judge the kitchen garbage quantity that the user drops into through detecting the commentaries on classics moment of torsion, adjusts the rotational speed to increase or reduce the impact force of pendulum to food waste. When the amount of food is large, the motor rotation torque is large, and the rotation speed of the driving motor needs to be increased. When food quantity is less, the motor rotating torque is less, the rotating speed of the driving motor can be reduced, the pendulum impact force is monitored in real time, the rotating speed is changed in real time, the impact crushing efficiency and the abrasion condition of cutter head parts are balanced, the cutter head and the motor are protected from operating, and the failure rate is reduced.

The current kitchen waste cutting and grinding condition can be judged by detecting the rotating torque, so that the rotating speed of the cutter head can be adjusted. When the cutter head rotates clockwise, the side edge part of the serrated knife clamps the fiber food residues into the clearance of the sharp pointed knife and cooperates with the pendulum bob to cut off the fibers so as to cut off long fibers.

In some embodiments, the method further comprises: step S13 and step S14;

in step S13, in response to the power-on command, the driving motor is controlled to rotate in the first rotation direction for a first preset time; the driving motor rotates in a first rotating direction, such as a counterclockwise direction, for example, 60 to 120 seconds when being started;

in step S14, in response to a first preset time end command of motor rotation, the driving motor is controlled to rotate in a second rotation direction, wherein the second rotation direction is opposite to the first rotation direction.

After the driving motor rotates in the first rotation direction for 60 to 120 seconds, for example, the driving motor rotates in a second rotation direction for a second preset time, for example, the clockwise rotation is performed for 60 to 120 seconds, and then the counterclockwise rotation is performed. Under the control of a preset instruction, the motor realizes positive and negative rotation, exerts the cutting and grinding effects and more effectively breaks food residues. The positive and negative rotation of the motor and the control of the speed are beneficial to protecting the motor, reducing the abrasion of a grinding part and prolonging the service life of a key core part of the processor.

During the rotation of the cutter disc 20 relative to the grinding ring 10, the food waste is moved due to the high-speed rotating centrifugal force of the cutter disc 20, the food waste impacts the first blade 21 and/or the second blade 21 on the cutter disc 20, so that the first blade 21 and/or the second blade 22 rotate relative to the cutter disc 20, due to the up-and-down staggering of the first blade 21, during the rotation of the first blade 21 and/or the second blade 22 relative to the cutter disc 20, the first cutting edge on the first blade 21 and the second cutting edge on the second blade 22 are in staggered overlapping fit to cut off the food waste such as flexible fibers, meanwhile, the food waste is impacted by the reciprocating swing of the breaking hammer 25, the lug 26 plays a guiding role on the breaking hammer 25, the food waste is favorably cut by the second cutting edge 261 at the top, and furthermore, the food is punctured and cut by the vertical knife, so that the food is further crushed by the cutting teeth 201 on the cutting blade 11, and the food waste is sufficiently discharged after multiple treatments.
