Washing machine water purifying system and washing machine

Abstract

The invention relates to a washing machine water purifying system. The system comprises a water purifying module which is connected with a washing machine body through a pipeline, and the water in thewashing machine is filtered by the water purifying module and returned to the washing machine; the water in the water purifying module is driven back into the washing machine by a first water pump; at least a water inlet and a water outlet are formed in the water purifying module, the water inlet is connected to a washing machine outlet through a first pipeline, the water outlet is connected to awashing machine water inlet through a second pipeline, the first water pump is disposed on the second pipeline, the first water pump is further connected with a flush water supply pipe to drive the water in the flush water supply pipe to enter the water purifying module from a clean water inlet, and the water purifying module is backwashed. The invention also relates to a washing machine providedwith the above described filtration system. The system performs backwashing on the water purifying module, thereby more effectively removing contaminants attached to the surface of a filter membrane,improving the filtration performance of the filter membrane and prolonging the service life of the filter membrane.

Description

technical field [0001] The invention relates to laundry equipment, in particular to a washing machine water purification system and a washing machine. Background technique [0002] Existing water-saving washing machines filter the washing water for reuse during the washing and rinsing stage. After long-term use of the water purification module, the sediment attached to its surface will cause blockage of the filter holes, which will reduce the filtration efficiency of the water purification module. Some water-saving washing machines generally use the mode of forward flushing on the filter membrane to remove the pollutants attached to the surface of the membrane, that is, the flushing water flow is in the same direction as the water flow when the filter membrane is filtering water. This washing mode cannot deeply remove the pollutants on the surface of the filter membrane. Pollutants, the flushing effect is average, making it difficult for the filter membrane to maintain good ...
