Method for controlling flocculation processing water of washing machine through turbidity measurement and washing machine

Abstract

The invention discloses a method for controlling flocculation processing water of a washing machine through turbidity measurement and the washing machine. The washing machine comprises a washing machine body and a water circulation processing system, wherein the water circulation processing system comprises a flocculation container used for performing flocculation processing on water discharged from the washing machine body; the flocculation container is provided with a turbidity detection device; whether the set condition is met or not is judged through detecting the turbidity of the water after the flocculation through flocculation agent putting in each time; and if the condition is not met, a measure of putting the set quantity of flocculation agents for realizing the flocculation processing on the water in different times is adopted until the set condition is met. The method of measuring the turbidity value is used for judging the putting of the flocculation agents; the method is simple; the putting quantity of the flocculation agents is precise; the defect of poor flocculation effect or even failure due to great error is avoided; the water circulation processing efficiency is improved; and the rinsing water is saved.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a circulating water-saving washing machine, in particular to a method for controlling washing machine flocculation treatment water through turbidity measurement and the washing machine. Background technique [0002] With the improvement of people's living standards, the washing machine has become one of the main household appliances in people's daily life. The washing process of the washing machine mainly includes several stages of washing, rinsing and drying. After entering the rinsing stage, in order to rinse off the stains and residual detergent, it is necessary to enter more water or perform more rinsing times to rinse the clothes, which will consume a lot of water resources, even if it is a water-saving drum washing machine. Clothes also need to be rinsed at least twice, and this process consumes at least 30L of tap water. Sometimes there are less stains on the clothes or le...

Problems solved by technology

[0007] However, because the flocculant is directly put into the water tank of the washing machine to treat the washing water, it will cause secondary pollution of the clothes by the flocculant

In addition, if the dosage of flocculant has a large deviation, the flocculation effect will deteriorate. When the amount is small, the floc particles are small and cannot be effectively stratified, and when the amount is too large, the floc density is large and cannot be effectively stratified. Both situations will make The filter screen of the filter container is severely clogged, cannot be drained normally, and is difficult to clean. The final result is that the process of flocculation treatment of water cannot be carried out normally.
