Control panel and washing machine and eccentricity sensing system control method for washing machine

By installing magnets and probes on the control panel of the washing machine, an eccentric sensing system is formed using the principle of magnetic field-induced current. This system can judge the stability of the spin-drying process in real time and adjust the spin-drying speed and acceleration, thus solving the problem of unbalanced spin-drying in the washing machine and achieving stable spin-drying.

AI Technical Summary

Technical Problem

Existing washing machines suffer from uneven spin-drying due to uneven load, which can easily cause the outer tub to collide with the machine body. Current technology cannot effectively guarantee stable spin-drying.

Method used

Magnets and probes are installed on the control panel of the washing machine. Utilizing the principle of magnetic field-induced current, the probes cut the magnetic field to generate induced current, collect instantaneous current values ​​and fluctuation frequencies, and form an eccentric sensing system to judge the stability of dehydration in real time and adjust the dehydration speed and acceleration.

Benefits of technology

It achieves stable control of the washing machine's spin-drying process, ensuring smooth spin-drying and improving the success rate of spin-drying.

Abstract

The present application provides a control disc seat, a washing machine and a control method of an eccentricity sensing system of the washing machine. The control disc seat comprises an upper magnet and a detection rod which can form an eccentricity sensing system. The present application also provides a washing machine, wherein an upper magnet and a detection rod are arranged on the control disc seat, and a lower magnet is arranged on the center of a rotating wheel of a pulsator. The detection rod is located in a magnetic field generated by the upper magnet and the lower magnet. Sensors for detecting instantaneous current value I and fluctuation frequency R are arranged at both ends of the detection rod. The present application also provides a control method of an eccentricity sensing system of a washing machine, which is executed on the washing machine provided with the eccentricity sensing system and the control disc seat. The washing machine starts to dehydrate. The dehydration stability Q is determined according to the instantaneous current value I and the fluctuation frequency R generated by the detection rod cutting the magnetic induction lines. The dehydration start speed and acceleration of the washing machine are determined according to the stability level. The above technical scheme and device can ensure the success rate of one-time dehydration and the stable dehydration of the whole machine.
