Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problems of limited eccentricity reduction effect of the existing drum washing machine, long time for eccentric compensation and inability to realize controllable and accurate compensation, the present invention provides a drum washing machine, which includes Inner cylinder, balance ring and active eccentricity compensation system. The balance ring is arranged on the inner cylinder. The active eccentricity compensation system includes a magnetic sliding assembly, an electromagnetic adsorption assembly, a locking assembly and a magnetic detection element. The magnetic sliding assembly is slidably arranged in the balance ring , the magnetic detection element can detect the position of the magnetic sliding assembly in the gimbal, the locking assembly can lock the magnetic sliding assembly at a set position in the gimbal, and the electromagnetic adsorption assembly can magnetically adsorb the magnetic sliding assembly when it is powered on. Magnetic slide assembly disengages from locking assembly

Embodiment 1

[0033] The locking assembly 4 is an elastic locking assembly, and the elastic locking assembly includes a spring, a sliding piece and a locking piece, wherein the sliding piece is connected to the sliding groove on the inner wall of the balance ring 1 (the sliding groove is along the circumferential direction of the inner wall of the balancing ring 1 Setting) sliding connection, the two ends of the spring are respectively connected with the sliding part and the magnetic slider 21, and the locking part includes a plurality of locking suction cups arranged circumferentially along the inner wall of the balance ring 1, when the electromagnetic adsorption assembly 3 is not energized, the spring Under the active force, one or several locking suckers will absorb the magnetic slider 21. When the electromagnetic adsorption component 3 is energized, the magnetic attraction force of the electromagnetic adsorption component 3 to the magnetic slider 21 is greater than the elastic force of th...

Embodiment 2

[0035] The locking assembly 4 is a magnetic locking assembly, which includes a magnetic slide rail and a locking piece, wherein the magnetic slide rail is arranged along the circumferential direction of the inner wall of the balance ring 1, and the locking piece includes a magnetic slide rail along the circumferential direction of the inner wall of the balance ring 1. The plurality of locking suckers provided, when the electromagnetic adsorption assembly 3 is not powered on, under the action of the magnetic attraction force of the magnetic slide rail on the magnetic slider 21, one or several locking suckers will absorb the magnetic slider 21, and the magnetic slider will When the adsorption assembly 3 is powered on, the magnetic attraction force of the electromagnetic adsorption assembly 3 to the magnetic slider 21 is greater than the magnetic attraction force of the magnetic slide rail to the magnetic slider 21, so that the electromagnetic adsorption assembly 3 will suck the ma...

Abstract

The invention belongs to the technical field of washing machines, and aims at solving the problems that an existing drum washing machine is limited in eccentricity reduction effect, long in eccentricity compensation time and incapable of achieving controllable and accurate compensation. To achieve the purpose, the invention provides a drum washing machine and a control method thereof. The drum washing machine comprises an inner drum, a balance ring and an active eccentric compensation system, wherein the balance ring is arranged on the inner drum; the active eccentric compensation system comprises a magnetic sliding assembly, an electromagnetic attraction assembly, a locking assembly and a magnetic detection element; the magnetic sliding assembly is arranged in the balance ring in a sliding mode; the magnetic detection element can detect the position of the magnetic sliding assembly in the balance ring; the locking assembly can lock the magnetic sliding assembly; and the electromagnetic attraction assembly can magnetically attract the magnetic sliding assembly when powered on, so that the magnetic sliding assembly can be disengaged from the locking assembly. According to the drum washing machine and the control method thereof, active, controllable and accurate compensation can be achieved, the eccentric compensation effect is improved, dewatering of a single piece of clothes can be achieved, and the user experience can be improved.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and specifically provides a drum washing machine and a control method thereof. Background technique [0002] The drum washing machine may be eccentric when dehydrating the clothes. The eccentricity will cause the drum washing machine to make a lot of noise, and when dehydrating a single piece of clothing, the drum washing machine may not be able to perform dehydration due to eccentricity. [0003] In the prior art, to solve the problem of eccentricity of the drum washing machine, a balance ring is generally installed on the inner drum of the drum washing machine, or a counterweight is added to the outer drum. The above two methods are for random compensation when the drum washing machine is eccentric. , the effect of reducing eccentricity is extremely limited, and the adjustment time of eccentricity compensation is long, and it is impossible to achieve controllable and accurate compensat...
