Balance ring and its drum washing machine

Abstract

The present invention relates to a drum washing machine balancing rings and, balancing ring using rollers as the mass balance is provided by the nip roller cage retaining the rollers constituting the groups of the annular housing, the balance shaft is mounted in the drum circle drum washing machine the simple and compact structure, to enhance the balance of the eccentric rotation tub, the washing machine efficiently reduce vibration during dehydration, reduce noise; holder separates the rollers, impact mitigation, reduce noise; aspect ratio may be changed the rollers this makes the structure dimensioned balancing ring cross section is more flexible; holder connecting a plurality of rollers forming a roller group, coordinated movement of the roller group can be part of a self-locking region has fallen by a roller lock-pull , enhance balance; holder may be connected to change the center distance between the rollers by the structure size, thereby changing the distribution of the angle between closely spaced group of rollers, when the tub is not eccentric rotation, to reduce vibration caused by the balancing ring.

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 random distribution of clothes, the clothes will always have an unbalanced distribution in the dehydration barrel, which is what we usually call eccentric load. When the dehydration barrel rotates at a 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 barrel to vibrate violently. The vibration of the dehydration barrel will cause severe vibration of the whole machine. These vibrations will not only generate a lot of noise, bring great discomfort to the user's senses, but also greatly reduce the service life of the washing machine machinery and electrical parts. When the eccentric load is large, it even directly causes damage to s...

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
