A washing machine and a control method therefor, wherein the washing machine comprises a water-containing barrel (2), a flocculation container (4) and a filtering container (5), and the water-containing barrel (2), the flocculation container (4), the filtering container (5) and then the water-containing barrel (2) are successively brought into communication in a loop; the flocculation container (4) is provided with a stirring mechanism (7) which stirs to accelerate the dissolution of flocculant and a washing mechanism (8) for flushing and washing an inner wall of the flocculation container; a rotatable filtering mechanism (9) and a filtering and self-washing mechanism (10) using water intake current to spray and clean the filtering mechanism are provided in the filtering container (5). When the washing ends, water is discharged into the flocculation container, and after the flocculation processing, the water is discharged into the water-containing barrel of the washing machine for rinsing after being filtered by the filtering container, and the processing procedure is circulated until the rinsing is completed; during the last rinsing processing, the flocculation generated in the circulated water flocculation processing is controlled to be discharged and the rinsing is completed. Using rinsing water to wash the flocculation container improves the automation degree, simplifies the structure and saves production cost.


A method for controlling water circulation and processing in a washing machine and a washing machine, the washing machine comprising 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.
