Gimbal device of rolling drum-type washing machine

Abstract

The invention discloses a gimbal device of a rolling drum-type washing machine. The gimbal device comprises at least two annular chambers which are in coaxial with a rolling drum and are arranged at the edge of the rolling drum, wherein at least one chamber is a sphere gimbal provided with a grounder; and at least one chamber is a liquid gimbal provided with flowing liquid. The two different counterweights of the grounder and the liquid are utilized for respectively generating at least two counterbalances with different reaction speeds, thereby improving equilibrium state of rotation when the rolling drum of the washing machine dehydrates. When the rotation speed is less than the point of resonance of the rolling drum and an outer drum, the liquid gimbal absorbs vibration. When the rotation speed exceeds the point of resonance and is stabilized, the sphere gimbal generates high degree of vibration to absorb the vibration of the outer drum. For offset exceeding sphere volume, the liquid gimbal absorbs the vibration. The gimbal device can restrain vibration amplitude of the outer drum when starting and stably rotating, and realizes the purposes of low vibration, low noise and low cost.

Description

technical field [0001] The invention relates to a balance assembly for preventing or reducing vibration on a washing machine, in particular to a balance ring device for a drum type washing machine. Background technique [0002] With the development of washing machine technology, the washing capacity of washing machines continues to increase, and the speed of dehydration and drying is also increasing. The problem of vibration and displacement of the dehydration drum during the dehydration and drying process has become more and more a problem for the continuous development of washing machine technology. the bottleneck. [0003] In order to overcome the eccentricity and vibration of the dehydration drum caused by the unbalanced load during the working process of the above-mentioned washing machine, a balance ring structure is used on the washing machine. In the previous design, the gimbal is divided into two types: liquid injection gimbal and ball gimbal, both of which are pas...

AI Technical Summary

Problems solved by technology

[0009] Although the prior art listed above discloses a technical solution in which a plurality of side-by-side filler cavities are arranged in the same balance ring to enhance the working balance of the washing machine, each filler cavity is filled with the same filler, which does not It can't eliminate the vibration of the outer cylinder caused by the unbalanced dehydration during the working process of the washing machine, and the drumming problem, especially for the different load eccentricity of the wet clothes in the drum, it can only be effective for a small range of load eccentricity, once the load is eccentric If the amount is too large, there will be problems with vibration and pumping of the outer cylinder
