In this embodiment, a control method applied to any one of the first to sixth embodiments is described, after detecting that an eccentric inclination occurs in a water containing barrel of the washing machine, the washing machine executes a deviation rectifying program to control a cam to rotate around a rotating shaft, and the cam pushes the water containing barrel to shake, so that loads in the barrel are uniformly distributed, and the leveling and deviation rectifying effects of the washing machine are further achieved. By the control method, the washing machine can directly push the water containing barrel to rock by the cam so as to perform uniform load distribution treatment in the barrel and adjust the gravity center of the water containing barrel to perform the effect of deviation correction. Therefore, the washing machine does not need to supply water into the water containing barrel to rinse the load again so as to realize deviation rectification treatment on the outer barrel, the water consumption of the washing machine is reduced, and the time consumption of a washing program is reduced.
In this embodiment, the manner of detecting the eccentric inclination of the tub of the washing machine may be any of the existing forms, for example:
a sensor is arranged on the washing machine to detect the axis offset angle of the water containing barrel in a static state, and after the detected angle exceeds a set angle, the water containing barrel is judged to be eccentrically inclined, and the washing machine needs to execute a deviation rectifying program;
and after the collision between the water containing barrel of the washing machine and the anti-collision rod arranged on the shell is detected, the water containing barrel is directly judged to be eccentrically inclined, and the washing machine needs to execute a deviation rectifying program.
In this embodiment, when the washing machine was carrying out the procedure of rectifying a deviation, the motor continued to work, drove the cam and revolve around the pivot for the water containing bucket produces constantly to produce the slope under the promotion of cam and rocks, rocks to the utilization is rocked the effort and is made the load in the bucket carry out the equipartition, and then reaches the effect of adjustment water containing bucket focus, rectifying a deviation to the water containing bucket.
In this embodiment, when the washing machine executes the deviation rectifying program, the inner tub in the water tub is controlled to operate at a set rotation-stop ratio, so as to improve the uniform distribution degree of the loads contained in the tub.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
