Washing machine dewatering method and device, storage medium and washing machine

Abstract

The invention provides a washing machine dehydration control method and device, a storage medium and a washing machine, and the method comprises the steps: controlling a motor of the washing machine to operate according to a first set rotating speed, collecting the Q-axis current of the motor, and calculating a first eccentric value according to the Q-axis current; if the first eccentric value meets the first preset condition, the motor is controlled to operate at a second set rotating speed, and the Q-axis current of the motor is collected, so that the weighing value of the clothes is calculated according to the Q-axis current; calculating a second eccentric value of the motor according to the first eccentric value and the weighing value of the clothes; if the second eccentric value meets a second preset condition, the motor is controlled to operate at a speed increasing speed according to a third set rotating speed, Q-axis current in the speed increasing process of the motor is collected, and a third eccentric value of the motor is calculated according to the second eccentric value and the Q-axis current in the speed increasing process; if the third eccentric value meets a third preset condition, the washing machine is controlled to dewater according to the set dewatering rotating speed. According to the scheme, the barrel collision probability can be reduced, and the dehydration performance is improved.

Description

technical field [0001] The invention relates to the control field, in particular to a washing machine dehydration control method, device, storage medium and washing machine. Background technique [0002] At present, most of the front-loading washing machines use BLDC motors to drive the inner tub of the washing machine. Due to the uncertainty of the state of the clothes, during the dehydration process, due to the action of centrifugal force, the internal system shakes, causing the cylinder to shift and other phenomena. In order to reduce the For the occurrence of this phenomenon, it is necessary to identify the sloshing situation at different stages, and carry out corresponding control according to the swaying amplitude at different stages, so as to reduce the occurrence of phenomena such as displacement of the barrel. The vibration sensor detects the vibration displacement, the cost is increased, and the reliability is low. Contents of the invention [0003] The main pur...
