Abstract
Disclosed are a water purifying module self-cleaning method and a washing machine using the method. The water purifying module self-cleaning method comprises: starting a water purifying module self-cleaning program to feed water into a washing machine to reach a preset level; and repeating a heating rinsing program and a clear water replacement rinsing program in sequence until detecting that the water purifying module is clean, wherein the heating rinsing program comprises a washing water heating step, a membrane rinsing step, a standing step and a membrane air washing step. The water purifying module self-cleaning method can peel off impurities, macromolecular particles and the like from the surface of a filter system (5) of a water purifying module, thus ensuring the water purifying effect of the water purifying module and effectively prolonging the service life of the water purifying module.
