Washing machine and dehydration control method and device thereof

Abstract

The invention discloses a washing machine and a dehydration control method and device thereof. The washing machine comprises a dehydrating barrel and a dehydrating motor for driving the dehydrating barrel to run. The method comprises the steps of obtaining a feedback rotating speed of the dehydrating barrel in real time when the washing machine executes a dehydration procedure; controlling the dehydrating motor according to the feedback rotating speed of the dehydrating barrel to ascend the dehydrating rotating speed of the dehydrating barrel in a wave form to avoid a resonance point of the washing machine; when the feedback rotating speed of the dehydrating barrel ascends to a first preset rotating speed, entering the washing machine into a long dehydrating stage; driving the dehydrating barrel to alternately run at a second preset rotating speed and a third preset rotating speed through controlling the dehydrating motor at the long dehydrating stage, wherein the second preset rotating speed is greater than the third preset rotating speed and greater than the first preset rotating speed. According to the dehydration control method, the dehydration performance of the washing machine can be improved, abrasion of the dehydrating barrel is reduced and the implementation cost is low. The invention further discloses a computer-readable storage medium.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a washing machine dehydration control method, a computer-readable storage medium, a washing machine dehydration control device and a washing machine. Background technique [0002] At present, when the washing machine is dehydrating, it is generally controlled by using a fixed ON / OFF time for the dehydrating motor. Although this method can also take away a large amount of water and rush through some resonance points, when the load is too large, the speed of the dehydration motor rises very slowly, which makes the feedback speed of the dehydration bucket rise slowly, and it is easy to cause the feedback speed of the dehydration bucket to not reach. When the target rotation speed is reached, the fixed ON time is reached, which will affect the dehydration performance of the washing machine and the resonance point. [0003] Moreover, in the high-speed dehydration stage of th...

AI Technical Summary

Problems solved by technology

If the dehydration performance can be achieved by inputting 50Hz AC, then when inputting 60Hz AC, the dehydration speed is too high, which may cause bad phenomena such as wear of the dehydration bucket

If the structure of the washing machine is to adapt to the high speed corresponding to 60Hz alternating current, it will inevitably increase the production cost
