Title:
OPERATION CONTROL METHOD AND SYSTEM FOR WASHING MACHINE MOTOR, WASHING MACHINE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/078046
Kind Code:
A1
Abstract:
An operation control method and system for a washing machine motor, a washing machine, and a computer-readable storage medium. The method comprises: controlling a rotor of a motor to perform accelerating rotation in a first rotation direction, acquiring a current rotation speed of the motor, and on determining that the rotation speed of the motor has reached a first target rotation speed (N1) and the operation has lasted for a first preset period of time (T1), controlling the rotation speed of the motor to continuously change from the first target rotation speed (N1) to a second target rotation speed (N2) without any stopping time; and on determining that the rotation speed of the motor has reached the second target rotation speed (N2) and the operation has lasted for a second preset period of time (T2), controlling the rotation speed of the motor to continuously change from the second target rotation speed (N2) to the first target rotation speed (N1) without any stopping time, wherein the direction of the first target rotation speed (N1) is opposite to the direction of the second target rotation speed (N2). In the process of switching between the first target speed (N1) and the second target speed (N2) of the washing machine in a washing process, a zero-speed stopping time is eliminated, thereby reducing clothes washing time.
