Problems solved by technology

[0003] In the actual operation process, the amount of eccentricity mapping under different weights of clothes is different, and it is necessary to set the threshold value of different eccentricity mapping parameters in each load stage. At this time, the reliability of eccentricity control will also be related to the accuracy of clothes weight detection. When the weight deviates, the threshold value will change. The phenomenon of the whole machine running caused by this change is that the cylinder is displaced or the dehydration time is long, and in some cases it is not dehydrated.

Abstract

The invention belongs to the field of washing machines, and in particular relates to a dehydration control method for a washing machine and a washing machine. The control method includes: after entering a dehydration process, obtaining an eccentricity value Pi of the washing machine at a set rotation speed; obtaining a target rotation speed of the current load, and controlling the washing machine Calculate the motor torque coefficient t when the speed is increased from the set speed to the target speed from the set speed to the target speed; the torque coefficient t is fitted with the eccentric value Pi to obtain the corrected eccentric value P, control the washing machine to perform dehydration control according to the corrected eccentricity value P. The dehydration control method of the present invention eliminates the eccentricity threshold value set according to weighing in the dehydration process by adding eccentricity compensation in the eccentricity detection process, and directly adopts the eccentricity threshold value setting, thereby reducing the displacement probability of the knocker cylinder, improving the dehydration performance, and reducing the problem of undesired clothes. A levelling process produced uniformly.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to a dehydration control method for a washing machine and a washing machine. Background technique [0002] At present, most of the washing machines on the market are controlled by PMSM motors. In order to detect the eccentricity caused by the uneven distribution of clothes inside the washing machine, each signal quantity of the detection motor is used to map the eccentricity. Therefore, the mapped eccentricity is proportional to the swing of the drum itself, which meets the basic requirements for detecting eccentricity. [0003] In the actual operation process, the amount of eccentricity mapping is different under different clothing weights, and it is necessary to set the threshold value of different eccentricity mapping parameters in each load stage. At this time, the control reliability of eccentricity will be related to the accuracy of clothing weight detection at the ...
