Problems solved by technology

If this method is used for dehydration, one case may cause the inner cylinder of the washing machine to hit the box, resulting in greater vibration noise, and may even cause the washing machine to shift, posing a safety hazard; another case may cause the washing machine to be delayed. Entering the predetermined dehydration speed for dehydration, there is a delay, and even the washing machine does not dehydrate

Abstract

The invention provides a dewatering control method of a roller washing machine, a medium and the roller washing machine. The method comprises a pre-dewatering stage and a final dewatering stage. The pre-dewatering stage comprises the steps of determining first load weight of a load and a first weight gear interval to which the first load weight belongs; performing rotation speed fluctuation detection on a motor to obtain a first rotation speed fluctuation value; and if the first rotating speed fluctuation value is below a rotating speed fluctuation limit value corresponding to the first weight gear interval, executing the pre-dewatering step. The final dewatering stage comprises the steps of determining second load weight of the load and a second weight gear interval to which the second load weight belongs; performing rotation speed fluctuation detection on the motor to obtain a second rotation speed fluctuation value, and determining a target rotation speed gear according to the second rotation speed fluctuation value and the second weight gear interval; and executing the final dewatering step. According to the method, the dewatering success rate of the small-weight load is increased, the time delay is shortened, the probability of displacement of the large-weight load due to box collision during dewatering is reduced, and the vibration and noise level is balanced.

Description

technical field [0001] The present application relates to the technical field of drum washing machines, in particular to a dehydration control method of drum washing machines, media and drum washing machines. Background technique [0002] At present, the motors used in many drum washing machines are series motors. In the dehydration stage of the drum washing machine, the dehydration logic usually used is: to judge whether the speed fluctuation is within the preset speed fluctuation limit, and when the speed fluctuation is within the preset speed fluctuation limit, the predetermined dehydration speed is used for dehydration . If this method is used for dehydration, one case may cause the inner cylinder of the washing machine to hit the box, resulting in greater vibration noise, and may even cause the washing machine to shift, posing a safety hazard; the other case may cause the washing machine to delay Entering the predetermined dehydration speed for dehydration, there is a...
