Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and reality
Execute example, the present invention is further elaborated.Only should be appreciated that specific embodiment described herein
Only in order to explain the present invention, it is not intended to limit the present invention.
The rotary drum washing machine vibration-proof structure of the present invention, including be arranged on the peripheral balance ring in dehydration barrel openend,
For reducing the mass of the intrinsic frequency that dehydration barrel is rocked, this mass is arranged on balance ring inside or dehydration
Bucket top.
The vibration attenuation mechanism of above-mentioned rotary drum washing machine vibration-proof structure is: actual clothing is at washing process distributing position not
Determine, when loading center of gravity and concentrating on dehydration bucket bottom, mainly cause the swing of dehydration barrel, and when load weight
When heart position concentrates on dehydration barrel top, rocking of dehydration barrel can be caused.Generally rock and be easier to make than swing
Become vibration big, hit case displacement, by applying mass inside dehydration barrel top or balance ring, reduce dehydration
The intrinsic frequency that bucket rocks, increases the range of speeds that balance ring plays a role, thus reduces the amplitude rocked.
Above-mentioned rotary drum washing machine vibration-proof structure, by be arranged on balance ring in or the mass at dehydration barrel top,
When washing machine works, reduce intrinsic frequency and amplitude that dehydration barrel is rocked, thus balance ring can be made very fast
Play a role, effective to solve dehydration barrel vibration big, the problem hitting case displacement.
