Abstract

The invention provides a drum washing machine, which includes a box body and an outer cylinder, and an avoidance opening is provided on the side wall of the box body in a collision-prone area for avoiding collision between the outer cylinder and the box body. On the premise of simple structure and easy implementation, the drum washing machine of the present invention effectively solves the problems of collision noise and displacement generated when the outer cylinder collides with the box body.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a structural improvement of a drum washing machine. Background technique [0002] During the dehydration process of the washing machine, if there is a violent shock, the drum will be bumped, which will not only easily cause the washing machine to shift, but also generate a lot of noise. In the prior art, in terms of program control, vibration reduction and displacement prevention are mainly achieved through eccentricity detection, water inlet drum balance eccentricity, adjustment of dehydration speed or motor stop ratio, and rapid passage through the resonance area. In terms of structure, dampers, Balance rings, counterweights, feet, etc. to achieve vibration reduction and displacement prevention. For example, CN201510428024.1 discloses that different intermittent dehydration sequences are selected corresponding to different water volumes, and the rotation speed of the ...
