Abstract

The invention provides a barrel collision detection method and device of a washing machine, a medium and the washing machine. The method comprises the following steps of sequentially obtaining acceleration values of an acceleration sensor in the washing machine, thereby obtaining the current acceleration value; and according to the fact that the current acceleration value is not within a preset acceleration limit value range and the absolute value of the difference value between the current acceleration value and the latest acceleration value exceeds the preset limit value, determining that barrel collision of the washing machine occurs, wherein the latest acceleration value is the acceleration value of the acceleration sensor obtained at the latest time before the current acceleration value is obtained. According to the method, the detection accuracy is high, barrel collision can be detected in time, the possibility of false detection is greatly reduced, and the phenomenon of repeated dewatering caused by false detection is avoided; and in addition, the method is simple in algorithm logic, low in cost, easy to implement, capable of guaranteeing detection timeliness and wide in application range.

Description

technical field [0001] The present application relates to the technical field of washing machines, in particular to a washing machine collision detection method, device, medium and washing machine. Background technique [0002] When most drum washing machines are dehydrating, they only detect the eccentricity in the tub at the low-speed stage, and no longer detect it at the high-speed stage. If there is a deviation in the eccentricity detection in the low-speed stage, it will cause excessive noise in the high-speed dehydration stage, and even barrel collision. Contents of the invention [0003] In the technical field of washing machines, in order to solve the above technical problems, the purpose of the present application is to provide a washing machine collision detection method, device, medium and washing machine. [0004] According to an aspect of the present application, a washing machine collision detection method is provided, including: [0005] Obtain the acceler...
