Embodiment Construction

[0029] Such as figure 1 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. The rotating shaft 13 of the inner barrel 7 is substantially horizontal.

[0030] Balance rings 10 are 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 . The balancing ring 10 is arranged coaxially with the inner barrel 7 . In other alternative implementations, the gimbal 10 may also be provided only at one end of the inner bucket 7 .

[0031] As shown in FIG. 2 , the gimbal 10 includes a housing 12 having an annular cavity 11 . There is a viscous fluid 15 and a...

Abstract

Provided is a balance ring used for a washing machine. The balance ring used for a washing machine comprises a housing with an annular inner cavity. The annular inner cavity is provided with a viscous fluid and a plurality of balls which can roll along the annular inner cavity. One side of the annular inner cavity, close to the center shaft of the annular inner cavity, is provided with a liquid retaining device. When the balance ring is static or rotates around the center shaft in velocity lower than first rotating speed, the viscous fluid is absorbed by the liquid retaining device, and is maintained in the liquid retaining device. Thus, the viscous fluid in the annular inner cavity is reduced, and viscosity force of the viscous fluid on the balls is reduced, so the balls are remained in relatively low positions of the annular inner cavity and are not pushed to cross the highest point of the annular inner cavity, so as to prevent the balls from colliding each other and preventing noise. The invention also discloses a washing machine including the balance ring.

Description

[0001] 【Technical field】 [0002] The invention relates to a washing machine and a balance mechanism of the washing machine. [0003] 【Background technique】 [0004] 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 be balanced during the rotation, thereby reducing the vibration and noise generated by the unbalanced rotation of the barrel, a balance ring can be installed on the barrel along the circumferential direction. A gimbal generally consists of a housing with an annular cavity, a ball that can move in the cavity of the ring, and a viscous liquid that has a certain lubricating effect and provides a viscous force. [0005] In the dehydration stage, due to the high rotational speed of the bucket, the sphere in the balance ring is automatically stabilized at the opposite position of the eccentric mass of the clothes, thereby offsetting the eccentric mass formed by the clothe...
