Description

Side plate structure of washing machine

Technical Field

The invention belongs to the technical field of washing machines, and particularly relates to a side plate structure of a washing machine.

Background

During the dehydration of the drum washing machine, the laundry tends to form eccentric masses inside the drum of the washing machine, which, during the dehydration of the washing machine, generate an alternating eccentric force on the drum, which is transmitted to the cabinet through springs, dampers, door seals, etc., causing the cabinet of the washing machine to vibrate. And the vibration of the lateral plate of the box body at the highest rotating speed for dewatering is a key factor for causing vibration noise of the washing machine. The vibration of the washing machine box body can be divided into box body integral swing and box body left and right side plate vibration, wherein the box body integral swing is mainly determined by the rigidity of the washing machine box body framework, and the vibration of the box body left and right side plates is completely determined by the thickness, the process modeling and the like of the side plates. In order to solve the problems in the prior art, the external shape of the side plate of the washing machine is mostly processed by pressing to form a rib pressing mode so as to enhance the rigidity of the side plate, but the existing side plate rib pressing mainly adopts a non-connected transverse rib or vertical rib structure, the rigidity and first-order inherent frequency of the side plate are lower by adopting the rib pressing mode, the vibration reduction and noise reduction effects are not obvious, and the user experience is poor; many users complain about the phenomenon that the drum-type washing machine is easy to run and shift under the conditions of washing large load, high water content and the like.
