Problems solved by technology

[0003] However, when the barrel reaches or is at a certain rotational speed (for example, between 30 and 80 revolutions), the balls in the annular channel are likely to collide with each other, thereby generating noise

Embodiment Construction

[0042] Such as figure 1 and figure 2 As shown, the washing machine 1 includes a box body 2 , and a drum system 5 suspended in the box body 2 through an elastic suspension unit 3 and a damping support unit 4 . The drum system 5 includes an outer tub 6 connected to the elastic suspension unit 3 and the damping support unit 4, an inner tub 7 coaxially installed in the outer tub 6, and a motor 8 for driving the inner tub 7 to rotate.

[0043] A balance ring 10 is respectively installed along the circumferential direction of the wall of the inner barrel 7 near the axial ends of both sides of the inner barrel 7 . Balance ring 10 comprises annular passage 11 and lubricating oil 13 ( image 3 ) and some balls 12 that can roll along the channel. The spheres 12 are arranged in a single row in the channel 11 , and the diameter of the spheres 12 is slightly smaller than the inner diameter of the channel 11 .

[0044] The balls 12 in the annular channels 11 include magnetic balls 12a ...

Abstract

The invention discloses a washing machine which comprises a bucket which can be rotated under driven of a motor, wherein an annular channel is disposed along circumferences of the bucket; multiple spheres which can roll along the channel are installed in the channel; and the multiple spheres comprise magnetic balls and non-magnetic balls which can be attracted by magnetic force. Because of attracting force of the magnetic balls, the multiple spheres can be attracted together to form a mass body, the spheres in the mass body do not collide, or a few of spheres on edges collide when rotational motion of the bucket is unstable, so that noise generated from sphere collision can be reduced effectively. The invention also discloses a balance ring used in the washing machine.

Description

【Technical field】 [0001] The invention relates to a washing machine and a balance mechanism of the washing machine. 【Background technique】 [0002] Washing machines typically have a tub that is rotatable by a motor. Clothes are washed and dehydrated in the tub. In order to make the barrel tend to balance during the rotation, thereby reducing the vibration and noise generated by the unbalanced rotation of the barrel, a balance ring is installed on the barrel along the circumference. The balance ring includes an annular channel and several balls installed in the channel and can roll along the channel. During the dehydration process of the high-speed rotation of the bucket, the ball automatically adjusts the distribution position according to the unbalanced distribution state of the clothes in the bucket, so that the whole bucket reaches or tends to be balanced. [0003] However, when the barrel reaches or is at a certain rotational speed (for example, between 30 and 80 revo...
