Balance ring and drum washing machine with same

Abstract

The invention relates to a balance ring and a drum washing machine with the same. The balance ring uses rollers as balance mass, roller groups which are formed by clamping the rollers by retainers and are arranged in an annular shell and the balance ring is coaxially installed on a rotary drum of the drum washing machine. The structure is simple and compact, the capacity of balancing the eccentric force in the rotary drum is enhanced, the vibration during spinning of the washing machine is effectively reduced and the noise is decreased; since the retainers isolate the rollers, the impact is relieved and the noise is further decreased; since the ratio of length to diameter of the rollers can be changed, the structural dimension design of the cross section of the balance ring is enabled to be more flexible; since the retainers are connected with a plurality of rollers to form the roller groups, partial rollers which fall into a self-locking area can be pulled out of the self-locking area due to collaborative movement of the roller groups and the balance capacity is enhanced; since the central distance between the connected rollers can be changed by changing the structural dimension of the retainers, so the distribution included angle of the densely arranged roller groups can be changed, and when no eccentric force exists in the rotary drum, the vibration caused by the balance ring is reduced.

Description

technical field [0001] The invention relates to a washing machine, in particular to a balance ring and a drum washing machine with the balance ring. Background technique [0002] During the dehydration process of the washing machine, due to the randomness of the distribution of clothes, there will always be an unbalanced distribution of clothes in the dehydration bucket, which is what we usually call eccentric load. When the dehydration bucket rotates at high speed, the centrifugal force generated by the eccentric load is equivalent to the exciting force in the forced vibration, which will cause the dehydration bucket to vibrate violently. The vibration of the dehydration bucket will cause severe vibration of the whole machine. These vibrations will not only produce a lot of noise and bring great discomfort to the user's senses, but also greatly reduce the service life of the washing machine's mechanical and electrical components. When the eccentric load is large, it may e...

AI Technical Summary

Problems solved by technology

Whether to redistribute clothes is random. The number of times to redistribute clothes mainly depends on the difficulty of uniform distribution of clothes, and also depends on the preset eccentric protection value. If this value is set large, the pass rate will be high and dehydration will be easy to achieve. , but the washing machine vibrates greatly, and the service life will be affected

On the contrary, if this value is set small, the vibration will be small, the washing machine will be protected better, but it is not easy to achieve dehydration, there will be no dehydration, or the dehydration lasts for a long time
