Counterweight balance ring for washing device

Abstract

The invention discloses a counterweight balance ring for a washing device. A hollow annular structure is formed in the balance ring, a plurality of permanent magnets are alternately arranged on the inner ring wall of the balance ring according to N poles and S poles, a plurality of counterweight components are arranged in the hollow annular structure, and each counterweight component is provided with a solenoid coil and can slide or keep static in the hollow annular structure by changing the current of the solenoid coil. According to the counterweight balance ring, eccentric loads are balancedby the aid of movable balancing weights, and the counterweight balance ring is simple in structure and easy to implement by the aid of a solenoid driven mode. When the washing device is in a no-loadstate, the balancing weights are uniformly distributed in the balance ring, and balance of a drum is ensured. When the washing device is in a high-speed dewatering state, eccentric loads are balancedby the movable balancing weights, and vibration of the drum is restrained. Noise and vibration generated in the washing, rinsing and dewatering process of a drum washing machine are effectively reduced, and running stability of the drum washing machine is improved.

Description

technical field [0001] The invention relates to a counterweight balance ring, in particular to a counterweight balance ring of washing equipment. Background technique [0002] With the development of technology, consumers have higher and higher performance requirements for washing equipment, such as washing machines, including reducing the vibration noise during washing and dehydration, improving the stability of washing machine operation, and avoiding collisions and displacements. Phenomena such as collision and displacement are usually caused by the eccentric load generated by the random distribution of clothes. When the washing machine spins and dehydrates at high speed, the eccentric load will generate an exciting force and cause the washing machine to vibrate violently. Noise will be generated during this process, and even resonance with the ground will occur, which will bring a lot of inconvenience to users. [0003] The invention aims at suppressing the vibration dur...

AI Technical Summary

Problems solved by technology

1. It can only balance the eccentric load of small loads within a certain range, and it is difficult to balance the eccentric load when the eccentric load is too large

2. This scheme allows the ball to move in viscous oil to balance the eccentric load, but the viscous oil will also hinder the movement of the ball, making it unable to quickly maintain dynamic balance

However, due to its multi-stage gear transmission, additional noise may be generated during the movement of the balance unit
