Abstract

The invention discloses a balance ring. The balance ring comprises an annular body; the body comprises a first annular cavity and a second annular cavity, a plurality of spheres made from non-magnetic materials are placed in the first annular cavity, and a plurality of magnetic blocks are placed in the second annular cavity. Magnetic induction lines of the magnetic blocks are cut when the spheres roll and generate magnetic eddy-current damping. According to the balance ring, the magnetic blocks are used for generating a magnetic field, the magnetic eddy-current damping generated by cutting the magnetic induction lines with the spheres is used for ensuring that the rotating speed of each sphere is close to that of a roller at the starting moment, the use of liquid is avoided, and the problem that liquid leakage occurs in the use process of the balance ring is thus avoided.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a balance ring, a control method for the balance ring and a washing machine. Background technique [0002] In the prior art, in order to solve the problem of dehydration vibration and noise, the washing machine usually uses a liquid balance ring to offset the eccentricity problem generated when the drum rotates. However, the liquid balance ring has disadvantages such as low anti-deflection ability and instability interval, as well as problems such as liquid leakage and large error of liquid filling rate due to processing technology. [0003] The prior art discloses a balancing ring device for a drum-type washing machine, which includes at least two annular chambers arranged on the edge of the drum, at least one of which is a spherical balancing ring with rolling balls, and at least one of the chambers is a The liquid balance ring with flowing liquid adopts a passive bal...
