Title:
METHOD FOR CONTROLLING IMPELLER WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/105500
Kind Code:
A1
Abstract:
A method for controlling an impeller washing machine. The impeller washing machine comprises an impeller, and an electric motor for driving the impeller to rotate. During the process of the electric motor driving the impeller to rotate, the impeller washing machine determines, according to working parameters of the electric motor, whether the rotation of the impeller is subjected to resistance, and controls the electric motor to drive the impeller to rotate anti-clockwise when it is determined that the rotation of the impeller is subjected to resistance. The impeller washing machine can accurately learn, in a timely manner and according to the working parameters of the electric motor, that the rotation of the impeller is subjected to resistance; and by means of controlling the electric motor to drive the impeller to rotate anti-clockwise, the situation wherein the impeller is continuously driven to rotate in the same direction when the frictional force between the impeller and clothes is relatively large or when the impeller is caught in the clothes, thus resulting in the clothes being damaged and a speed reducer shaft also being excessively stressed, thereby shortening the service life and even causing damage is avoided.
