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.

Embodiment Construction

[0036] figure 1 is a schematic structural diagram of a vibration damping and balancing device 100 according to an embodiment of the present invention; figure 2 Yes figure 1 A schematic cross-sectional view of the annular body 110 of the vibration damping balancing device 100 shown. see figure 1 and figure 2 , the vibration damping and balancing device 100 may include an annular body 110 and a plurality of guide tubes 120 at least partially extending in the longitudinal direction. The annular body 110 has a plurality of liquid inlet channels 111 distributed along the circumferential direction to receive the fluid injected from the outside of the vibration damping and balancing device 100 . The beginning ends of the guide pipes 120 are configured to be fixedly connected with the plurality of liquid inlet channels 111 respectively, so as to discharge the fluid to the outside of the vibration damping and balancing device 100 .

Abstract

The invention provides a vibration damping balance device. The vibration-damping balance device includes: an annular body with a plurality of liquid inlet passages distributed along the circumference to receive the fluid injected from the outside of the vibration-damping balance device; The starting ends are respectively fixedly connected with a plurality of liquid inlet channels so as to discharge the fluid out of the vibration damping and balancing device. The vibration damping balance device of the present invention can be installed in a rotating device that uses fluid in the working process and eccentricity occurs in a specific area. By injecting fluid into the guide tube on the opposite side of the eccentricity, the eccentricity of the eccentric side is offset to make the rotating device better balance and reduce vibration noise.

Description

technical field [0001] The present invention relates to the field of rotating devices, in particular to a vibration damping and balancing device and a vertical pulsator washing machine with the same. Background technique [0002] During the spin-drying period of the pulsator washing machine, due to the eccentricity of the clothes and the resonance of the system, the system vibrates greatly during high-speed spin-drying, and at the same time produces 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 set at the upper end or the lower end of the inner tub of the washing machine, and the purpose of balancing the load is achieved by injecting a balance liquid into the balance ring. However, this kind of gimbal structure can only reduce the number of hit boxes (the outer tub of the washing machine collides with the cabinet) through the hy...
