Washing machine water cycle treatment control method and washing machine

Abstract

Disclosed are a method for controlling water circulation and processing in a washing machine and a washing machine. The washing machine comprises a washing machine main body (1) and a water circulation and processing system (2). The water circulation and processing system (2) comprises a flocculation container (5) for flocculating the drained water from the washing machine main body (1), the flocculation container (5) being provided with a water level detection apparatus (4). After water is used by the washing machine for washing laundry, the water circulation and processing system (2) subjects the water to flocculation and then circulates same for re-use, and, according to the amount of detergent dosed, the amount of water intake for washing, and the amount of water processed in each flocculation, calculates the dose of flocculant needed for the water to be processed by the flocculation process this time. The dose of flocculant can be precisely calculated by measuring and calculating the amount of water intake for washing and the amount of water to be processed for each flocculation so as to ensure flocculation effects. Furthermore, by calculating the height of flocculation product after layer separation by means of the flocculant dose, using a water level measurement can entirely separate a clean water layer, such that more water joins the circulation for use, saving more water, and enabling flocculated matter to be prevented from mixing with the circulating clean water, improving flocculation efficiency.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a cycle water-saving method for washing machines, in particular to a washing machine water cycle treatment control method and a 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 less detergent is put in, and it may be rin...

Problems solved by technology

[0008] 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.
