Eccentricity detection method for washing machine

Abstract

The invention provides an eccentricity detection method for a washing machine. The method comprises the following steps: S1, entering a washing procedure; S2, reading the value of an acceleration sensor to obtain an inclination angle of a corresponding outer drum; S3, judging whether the inclination angle of the outer drum is greater than a preset value; S4, if the judgment result is yes, controlling a motor to perform a certain period of time of eccentric treatment, then returning to S3, and if the judgment result is no, entering next step; S5, judging whether the washing time is ended; and S6, if the judgment result is yes, detecting and correcting the inclination angle and then ending the washing procedure, and if the judgment result is no, returning to S2. The method provides an active detection mode, namely whether the washing machine is eccentric during washing and bleaching is detected by utilizing the acceleration sensor, and the corresponding eccentric treatment is performed if the washing machine is eccentric, so that a drum collision phenomenon caused by high eccentricity during dewatering in the washing machine is avoided, and the service life of the washing machine is prolonged.

Description

technical field

[0001] The invention relates to the field of washing machines, in particular to a washing machine eccentricity detection method. Background technique

[0002] As a daily household appliance, the washing machine liberates people from the work of washing clothes, so it is popular among users. It mainly includes a cabinet, an outer tub, an inner tub, a pulsator, a motor and a control panel; the pulsator is located in the inner tub. The inner barrel is located in the outer barrel, and the outer barrel is suspended on the box body through a suspender, and the control board controls the motor for washing and dehydration. When the washing is completed, the washing machine dehydrates. The existing dehydration method of the fully automatic pulsator washing machine is that the clothes move under the drive of the inner barrel, and the dehydration effect is achieved through the action of centrifugal force. When the clothes are not evenly distributed, the dehydration is e...
