Abstract

The invention provides a washing machine drainage control method and belongs to the field of washing device control. The invention aims to solve the problem of poor automatic cleaning effect of filter screens of the conventional washing machines. The washing machine drainage control method is characterized in that the rotating speed of an inner barrel and / or an impeller is controlled in a drainage process and the flow speed of washing liquor is controlled by controlling the rotating speed of the inner barrel and / or the impeller to clean a filter screen through back flushing. The washing machine drainage control method improves the filter screen cleaning effect; the rotation of the inner barrel and / or the impeller increases the discharge speed of the washing liquor, so that the filter screen cleaning effect can also be improved. When the water level is relatively low, the inner barrel and / or the impeller rotate(s) at a relatively high speed and wave-like high speed rotating water flow containing a large number of bubbles is generated in the inner barrel; the high speed wave-like bubble water flow can wash thread residues attached to the filter screen away, so that the filter screen is cleaned automatically.

Description

technical field

[0001] The invention relates to a washing machine drainage control method. Background technique

[0002] The washing machine generates or separates lint, debris, small impurities, etc. during the washing process. These substances are easy to stick to the clothes and affect the cleaning effect of the clothes.

[0003] In order to solve this problem, a water hole is opened on the bottom side of the inner barrel of the existing washing machine, and a filter screen is installed at the bottom of the inner barrel. The lint is filtered through the filter, the lint is collected, and the lint is automatically removed.

[0004] The effect of the filter screen in this washing machine structure is remarkable, but because the water flow rate of the reverse flushing filter screen is weak when the pulsator washing machine is drained, it is difficult to thoroughly rinse the filter screen. After a long time, it is easy to cause the blockage of the filter screen and affect ...
