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

Provided is a balancing ring used for a washing machine. The balancing ring comprises a housing with an annular inner cavity. The annular inner cavity is internally provided with at least mass bodies capable of moving along the annular inner cavity. Centripetal sides of the mass bodies are provided with first magnets. The centripetal side of the housing is provided with an attraction part which can be attracted by magnetic force. Each balancing ring remains static or rotates around a central shaft at the speed lower than the pre-set rotation speed. The mass bodies are fixed by magnetic attraction of the first magnets and the attraction part. The mass bodies and the housing of the balancing ring rotate as a whole. When the balancing ring rotates around the central shaft at the speed higher than or equal to the pre-set rotation speed, centrifugal force enables magnetic attraction to be overcome. The mass bodies can move in the annular inner cavity at the proper position to achieve balance. The invention further discloses the washing machine having the balancing 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...
