Automatic detergent feeding control method, automatic detergent feeding device and washing machine with same

Abstract

The invention provides an automatic detergent feeding control method. The automatic detergent feeding control method includes the steps: S1, after a washing machine is started, obtaining water volume needed by washing of the washing machine; S2, detecting temperature of a detergent storage box in the washing machine; S3, inquiring preset mapping tables to obtain working time of a current detergent feeding pump according to the water volume needed by washing of the washing machine and the temperature of the detergent storage box, wherein the preset mapping tables include a mapping table of water level-environment temperature range-detergent feeding pump working time; and S4, controlling the detergent feeding pump to work according to the working time of the current detergent feeding pump. By the control method, clothes can be guaranteed to be washed cleanly, detergent residue is reduced, washing effect is improved, and energy saving and environmental protection are achieved. Besides, the invention provides an automatic detergent feeding device and the washing machine with the same.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a control method and device for automatic detergent injection and a washing machine with the detergent automatic injection device. Background technique [0002] At present, the realization of the detergent automatic feeding function of the fully automatic pulsator washing machine is mainly based on the fuzzy weighing results to judge the amount of clothes, and determine the water consumption corresponding to the amount of clothes, and then control the detergent feeding pump according to the fixed ratio of detergent concentration. Working time is to control the dosage of detergent. The above-mentioned control method of automatic injection of detergent does not consider the influence of temperature on the amount of detergent injected. For example, the fluidity of the same brand of detergent varies greatly under different ambient temperatures. When the ambient temperature i...

Problems solved by technology

The above-mentioned control method of automatic injection of detergent does not consider the influence of temperature on the amount of detergent injected. For example, the fluidity of the same brand of detergent varies greatly under different ambient temperatures. When the ambient temperature is low, the detergent becomes viscous. , if the working time of the injection pump is the same as that at room temperature, the actual amount of detergent injected will be too small, which will affect the washing efficiency, and the clothes will be easily washed unclean

In addition, different brands of washing liquid have different degrees of concentration. If the ratio of water or washing liquid is fixed according to the ratio, when washing very dirty clothes, it is easy to have insufficient detergent or the clothes are not clean. When washing clothes that are not too dirty, it is easy to rinse uncleanly due to excessive washing liquid

[0003] To sum up, the disadvantages of the existing automatic detergent injection technology are that it is easy to cause waste of washing liquid, unclean clothes or residual detergent, etc., and the washing effect is poor.
