Dehydration control method and system of washing machine and washing machine comprising dehydration control system

Abstract

The invention belongs to the technical field of washing machines, particularly provides a dehydration control method and system of a washing machine and the washing machine comprising the dehydrationcontrol system. The method aims at solving the problem that an existing dehydration method cannot solve the problem that water-proof clothes block water outlet holes. For the purpose, the dehydrationcontrol method comprises the following steps that a dehydration program is started; the changes of the water level of an outer cylinder are detected to judge whether or not a dehydration cylinder canconduct normal dehydration operations; according to the detected water level changes, the revolution speed of the dehydration cylinder is controlled. By detecting the changes of the water level of theouter cylinder, it can be judged whether or not water in the dehydration cylinder flows through the water outlet holes in the dehydration cylinder to the outer cylinder, so that whether or not the water-proof clothes block the water outlet holes in the dehydration cylinder is judged, and when it is judged that the water can normally flows through the water outlet holes, the dehydration cylinder conducts the dehydration operation at the normal revolution speed; when it is judged that the water outlet holes are blocked by the water-proof clothes, the revolution speed of the dehydration cylinderis reduced, therefore bad conditions of strenuous vibration and loud noises of the washing machine are effectively avoided, and the dehydration effect of clothes is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and specifically provides a washing machine dehydration control method and system and a washing machine including the system. Background technique [0002] The washing machine is a clean electrical appliance that uses electric energy to wash clothes. With the acceleration of the pace of life and people's high requirements for living comfort, the washing machine has become an important household appliance in people's daily life. The current washing machine generally has a dehydration function, so that the washed clothes can be dried faster, which meets the needs of people with a fast pace of life. However, when the washing machine dehydrates some waterproof clothing, there will be a problem that the waterproof clothing will block the water outlet hole of the dehydration bucket, which greatly reduces the dehydration effect of the washing machine. [0003] In the dehydration control of the...
