A magnetic levitation control device, a drum washing machine and a magnetic levitation control method thereof

Abstract

The invention discloses a magnetic levitation control device, a drum washing machine and a magnetic levitation control method thereof. The device comprises a sensing device which is used for acquiringeccentric amount of an inner drum when an inner drum rotor is unbalanced during operation of the drum washing machine to be controlled and acquiring magnetic field strength of the drum washing machine during operation and a controller configured to dynamically adjust a magnetic drive force of a magnetic pole in a magnetic levitation module of the drum washing machine according to the eccentric amount and / or to correct the rotational speed and position of the inner drum rotor according to the magnetic field strength. The device can solve the problem that the eccentric force of the magnetic levitation drum washing machine is different when the external disturbance is large and clothes are at different positions, the inner drum is not stable and deviates from an equilibrium position, a levitated object fails to be levitated, and the effect of avoiding the circumstance that the levitated object fails to be levitated is achieved.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a magnetic levitation control device, a drum washing machine and a magnetic levitation control method thereof, in particular to a washing machine flexible magnetic levitation control device, a drum washing machine and a flexible magnetic levitation control method thereof. Background technique [0002] The current drum washing machine has a large operating noise. In the traditional structure, it is necessary to use counterweights to balance the washing machine during operation, and the washing machine is too heavy. In the case of high-speed operation of the washing machine motor, a prominent problem is the friction and wear of the mechanical bearings, and some parts will wear out and fail, which will cause uneven air gaps in the motor in severe cases. [0003] In patent documents such as application publication number CN106702657A, a magnetic levitation drum w...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to address the above defects, to provide a magnetic levitation control device, a drum washing machine and a magnetic levitation control method thereof, so as to solve the problem that the eccentric force of the magnetic levitation drum washing machine is not the same when the magnetic levitation drum washing machine is subjected to large external disturbances and when the clothes are in different positions. The cylinder is unstable and deviates from the equilibrium position, causing the suspension of the suspended object to fail, so as to avoid the suspension failure of the suspended object
