Washing machine and balance device used for washing machine

Abstract

The invention provides a balance device used for a washing machine and a washing machine provided with the balance device used for the washing machine.The balance device used for the washing machine comprises a lower ring groove, an upper ring groove, a ring pipe and a plurality of balance balls.The upper ring groove is formed in the lower ring groove in a covering mode to define an annular balance cavity channel, the ring pipe is arranged in the upper ring groove, and the balance balls are movably arranged in the ring pipe.Balance liquid such as salt water is contained in the annular balance cavity channel, so that the balance device used for the washing machine has the functions of liquid balance and mechanical balance, the advantages of liquid balance and mechanical balance are integrated, the disadvantages of liquid balance and mechanical balance are made up, and the optimal integrated balance effect is achieved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a balancing device for a washing machine and a washing machine with the balancing device for a washing machine. Background technique [0002] In order to reduce the vibration during the dehydration of the washing machine, a balance device for balancing the rotating eccentric mass is usually installed on the dehydration drum of the washing machine. Commonly used balancing devices include liquid balancing devices and mechanical balancing devices. Liquid balance devices, such as saline balance rings, are very popular for their low cost, strong anti-eccentricity, and diverse structural designs. The deviation correction ability is poor at low speed / acceleration, and even the eccentricity will be increased in a short period of time. Mechanical balance devices, such as steel ball balance rings, respond quickly when the dehydration bucket rotates, and can quickly correct d...

Problems solved by technology

Liquid balance devices, such as saline balance rings, are very popular for their low cost, strong anti-eccentricity, and diverse structural designs. The deviation correction ability is poor at low speed / acceleration, and even increases the eccentricity in a short period of time

Mechanical balance devices, such as steel ball balance rings, respond quickly when the dehydration bucket rotates, and can quickly correct deviations. However, due to the shape of the ball and the structure of the raceway, it is difficult due to the centrifugal force of the steel ball itself at high speed. Stably keep the eccentric mass of the dehydration barrel balanced in the raceway, especially when the eccentricity is large, the balance effect of the steel ball balancing device is not ideal
