Problems solved by technology

However, this kind of balance ring structure can only reduce the number of collisions (collisions between the outer tub and the casing of the washing machine) through the hysteresis of the liquid flow during the low-speed start-up stage of the washing machine.

Abstract

The invention provides a vibration damping and balancing device. The vibration damping and balancing device comprises an annular machine body and a plurality of guide pipes, wherein the annular machine body is provided with a plurality of liquid inlet passages distributed in the circumferential direction to receive a fluid injected from the outside of the vibration damping and balancing device; atleast a part of each guide pipe extends in the longitudinal direction, and starting ends of the guide pipes are fixedly connected with the liquid inlet passages respectively to discharge the fluid tothe outside of the vibration damping and balancing device. The vibration damping and balancing device can be set to use the fluid during work, and in a rotating device having eccentricity in a specific area, by injecting the fluid into the guide pipes opposite to the eccentricity, the eccentricity of an eccentric side is offset, so that the balance of the rotating device is better, and the vibration noise is reduced.

Description

technical field [0001] The invention relates to the field of rotating devices, in particular to a vibration-reducing balance device and a vertical pulsator washing machine with the vibration-reducing balance device. Background technique [0002] During the dehydration period of the clothes washing machine, due to the eccentricity of the clothes and the resonance of the system, the system vibrates greatly during high-speed dehydration, and at the same time generates a large noise, which makes the user feel uncomfortable, especially starting the washing machine at night will affect the user's rest sleep. [0003] In the prior art, a balance ring is usually provided on the upper or lower end of the inner tub of the washing machine, and the purpose of load balancing is achieved by injecting a balance liquid into the balance ring. However, this kind of balance ring structure can only reduce the number of collisions (collisions between the outer tub of the washing machine and the...
