washing machine dehydration method

Abstract

The invention relates to the technical field of washing machines, in particular to a method for dehydrating a washing machine, aiming to solve the problem of how to start and stop the drain pump on demand during the dehydration and drainage process of the upper drain washing machine in the prior art, and how to suppress foam during the stoppage of the drain pump Rapidly proliferating technical problems. The method includes: starting the washing tub of the washing machine to rotate after the washing and draining is completed; at the same time, before or after starting the rotation of the washing tub, causing the drain pump of the washing machine to enter an initial operation stage; While, before or after the drain pump enters the initial operation stage, the value of the liquid level sensor of the washing machine is collected in real time; based on the value of the liquid level sensor, the operation of the drain pump is controlled. By adopting the above-mentioned technical means, the present invention effectively solves the technical problem of how to control the action sequence of the drain pump in an energy-saving manner and effectively suppress foam growth during the dehydration and drainage process of the top drain washing machine.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a washing machine dehydration method. Background technique [0002] Although the washing powder or laundry liquid in the prior art can achieve the technical effect of cleaning clothes after being added into the washing machine, it will increase the liquid viscosity of the washing water. When the washing machine is working, the above-mentioned washing water will form a large amount of foam in the washing bucket. Upper drainage and lower drainage are two common drainage methods adopted by washing machines with different structures. Washing machines with lower drainage structure are usually most pulsator washing machines and some drum washing machines. The outlet is set at the lower part of the washing machine, and the water is directly discharged from the outlet by using the pressure of the washing water itself. The structure is simple, no additional electricity is requir...

AI Technical Summary

Problems solved by technology

Furthermore, if excessive washing powder or laundry detergent is put into the washing machine, during the dehydration and drainage process, a large amount of foam will surge in the washing tub, which will greatly increase the working pressure in the washing tub, and further cause: the washing tub cannot be properly processed. The dehydration speed of the water and washing tub cannot be increased normally, the moisture and foam adsorbed on the clothes cannot be removed normally, the foam is formed in the washing tub to breed internal circulation, and more foam is continuously generated on the basis of the original foam in the washing tub, etc.

In addition, when the foam overflows due to excessive pressure in the washing tub, it will even further cause water leakage.
