Washing machine dewatering control method and device and washing machine

Abstract

An embodiment of the invention provides a washing machine dewatering control method and device and a washing machine and relates to the field of washing equipment. By the method, collision of a box and large displacement of an inner-outer barrel assembly at the moment of starting a dewatering time sequence can be avoided. The method includes: after a washing program is finished and completion of draining of the washing machine is determined, acquiring a center position of the inner-outer barrel assembly of the washing machine; determining weight of clothes according to vertical component of a center position and vertical component of an initial center position of the inner-outer barrel assembly, and determining eccentric parameters of the inner-outer drum assembly according to the center position and the initial center position of the inner-outer drum assembly, wherein the initial center position of the inner-outer drum assembly is measured in an empty-bucket state; generating a dewatering time sequence according to weight of the clothes and the eccentric parameters. The method is used for dewatering control of the washing machine.

Description

technical field [0001] Embodiments of the present invention relate to the field of washing equipment, in particular to a washing machine dehydration control method and device, and a washing machine. Background technique [0002] During the dehydration process of the washing machine, the vibration of the inner and outer cylinder assembly is large, and phenomena such as collision with the box body and large displacement of the inner and outer cylinder assembly are common, resulting in poor user experience. [0003] In the prior art, the position sensor is mainly installed on the suspension system of the washing machine. During the dehydration process, the position sensor feeds back the displacement of the inner and outer cylinder assembly to the control panel of the washing machine, and the control panel judges whether the displacement of the inner and outer cylinder is based on the displacement. Exceed the standard, and then deal with it accordingly, using this feedback mecha...

AI Technical Summary

Problems solved by technology

Among them, the position offset can only be detected during the movement process of the inner and outer cylinders (that is, during the dehydration process after the dehydration sequence is started), so it can avoid phenomena such as hitting the box body and large displacement of the inner and outer cylinder assemblies during the dehydration process; but , before starting the dehydration process, due to the presence of water-containing clothes in the washing machine, the inner and outer cylinder assemblies may not be in a balanced state. The feedback mechanism has not yet been activated, and the phenomenon of collision with the box body and large displacement of the inner and outer cylinder assemblies is unavoidable
