Anti-collision drum method and device for drum washing machine and drum washing machine

Abstract

The present application proposes an anti-collision cylinder method and device for a drum washing machine, and the drum washing machine. The method includes: a processing module acquires the acceleration of the drum in the drum washing machine collected by an acquisition module; and a processing module calculates the acceleration of the drum according to the acceleration. Displacement, and judge whether the displacement of the drum is greater than the preset threshold; if so, the processing module controls to turn on the electromagnetic module electrically connected to the processing module, so that the electromagnetic module generates a force that acts on the drum and is in the same direction as the drum. and an acting force in the opposite direction of the displacement, so that the displacement of the drum is reduced below the preset threshold under the action of the acting force. When the application detects that the displacement of the drum is greater than the preset threshold, the electromagnetic field generated by the electromagnetic module causes a mutually repulsive reaction force between the drum and the box, avoiding the collision between the drum and the box, without decelerating and restarting the dehydration process, The anti-collision barrel is realized without wasting resources and without affecting the dehydration efficiency.

Description

technical field [0001] The present application relates to the technical field of washing machines, in particular to an anti-collision cylinder method and device for a drum washing machine and a drum washing machine. Background technique [0002] With the development of living standards and technology, front-loading washing machines are increasingly developing towards large capacity and high speed. However, a washing machine with a larger capacity is more prone to eccentric vibration when a large amount of clothes are placed for dehydration after washing. The phenomenon of displacement during dehydration will generate a lot of vibration and noise, and also reduce the service life of the drum washing machine, resulting in a poor user experience. [0003] In the current technical solution, it can detect whether the eccentricity of the drum occurs during the rotation process. When the eccentricity of the drum is detected, the deceleration is controlled to stop the operation, an...

AI Technical Summary

Problems solved by technology

In this solution, although the collision between the drum and the washing machine box is prevented to a certain extent, it is necessary to forcibly decelerate until it stops running, and then restart the dehydration process. While realizing the anti-collision cylinder, it also leads to large power consumption and water consumption. problems, and prolong the laundry time, affecting the laundry efficiency
