The invention discloses a control method and device of a washing machine. The control method of the washing machine comprises the steps that firstly, in the dewatering process, the rotating speed of a motor is controlled to increase the rotating speed of a washing drum of the washing machine; secondly, the first average value T1 of the torque changing amount of the motor when the rotating speed of the washing drum is increased to a second preset rotating speed from a first preset rotating speed is acquired; thirdly, whether the eccentric amount is larger than a preset threshold value or not is judged according to the first average value T1 of the torque changing amount; fourthly, if the eccentric amount is larger than the preset threshold value, the washing machine is controlled to enter a loose shaking process; fifthly, if the eccentric amount is smaller than the preset threshold value, the washing machine is controlled to continue the dewatering process. According to the control method and device of the washing machine, the washing machine can be intelligently controlled by judging the eccentric amount under the condition that the number of hardware devices is not increased, higher intelligence is achieved, the precision is improved, and cost is reduced.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to a control method and device for a washing machine. Background technique [0002] Dehydration (spin-drying) is a function of the washing machine. It mainly drives the dehydration bucket to rotate at high speed through the motor, and uses the centrifugal force generated by the high-speed rotation to separate the water in the clothes. However, during the dehydration process, due to the uneven placement of the clothes, the eccentricity problem will occur when the dehydration bucket rotates. If the eccentricity is too large, it may cause damage to the washing machine. [0003] At present, the pulsator washing machine mainly uses a mechanical door switch or a detection sensor, such as a speed detection sensor, is installed in the washing machine to judge the eccentricity. [0004] However, the method of using a mechanical door switch is not precise enough, and the method...
