Problems solved by technology

In the initial stage of dehydration, as well as the washing and rinsing stages of the washing process, the rotation speed of the bucket is low, and the mass body in the balance ring will move relatively, resulting in collision noise

Embodiment Construction

[0023] 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.

[0024] 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 balance ring 10 is arranged coaxially with the inner barrel 7 and has a central axis 11 . In other alternative implementations, the gimbal 10 may also be provided only at one end of the inner bucket 7 . In addition, the present invention is also applicable to the washing machine in which the inner tub 7 is t...

Abstract

A balance ring for a washing machine, comprising a housing with an annular cavity, in which there are at least two mass bodies that can move along the annular cavity, a first magnet is provided on the centripetal side of the mass body, and the shell The centripetal side of the body has an attractor that can be attracted magnetically. When the balance ring is stationary or rotates around the central axis at a speed lower than a predetermined speed, the mass body is fixed by the magnetic attraction force of the first magnet and the attractor, and the mass body and the housing of the balance ring rotate integrally; on the other hand, when the balance ring rotates around the central axis When rotating at a predetermined rotational speed or higher, centrifugal force causes the magnetic attraction force to be overcome, and the mass body can move in the annular inner cavity, so as to move to a proper position to achieve balance. The invention also discloses a washing machine with a balance ring.

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 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 balance ring generally includes a housing with an annular inner cavity, a mass body that can move in the inner cavity of the ring, such as a sphere, a group of spheres or other shaped moving bodies, and a viscous liquid that has a certain lubricating effect and provides viscous force. [0003] In the dehydration stage, when the rotational speed of the bucket is higher than its resonance rotational speed, the mass body in the balance ring is automatically stabilized at the o...
