A method for controlling release amount of detergent and a washing device, include: dividing inner space of a detergent box into independent N compartments, wherein each of the compartments is configured to store a type of detergent having a certain concentration range; assigning a concentration level Ci, i=1, . . . , N to each of the compartments wherein the higher the detergent concentration, the lower the concentration level; selecting one of the compartments containing detergent and releasing the detergent in the selected compartment, and obtaining the concentration level C of the selected compartment; obtaining a laundry weight m; and calculating a release amount of the detergent, wherein Vn=1.25*m*(C+1). The formula which is configured to calculate the release amount of detergent is also provided based on both of the detergent concentration level and the laundry weight. Hence, the problem of excess foaming and residue caused by putting too much concentrated detergents which have to introduce more rinsing cycles could be effectively solved.

Method for controlling release amount of detergent, and washing machine

A washing machine including: a first drainage pump arranged between a washing drum and a filter membrane assembly. The first drainage pump pumps water in the washing drum into the filter membrane assembly for filtration and ensures that a water level in a water inlet cavity of the filter membrane assembly is not higher than a lower edge of a sewage outlet, so as to prevent reduce of the amount of washing water due to drainage of excessive washing water/rinsing water. Since the first drainage pump is a low-lift water pump, water in the filter membrane assembly moves continuously during filtration, so as to scour pollutants on a surface of a filter membrane/membrane filament, reduce an accumulation degree of the pollutants, effectively prevent blockage and achieve low noise.
