Document Type and Number:
WIPO Patent Application WO/2017/076218
Kind Code:
A1
Abstract:
A maintenance method for a water purification device of a water-purifying washing machine and a water-purifying washing machine. The washing machine comprises: a washing drum, a circulating water pipeline, a drainage pipeline, and a membrane module. The membrane module is provided with a water inlet (1), a water production hole (4), and a sewage outlet (3); the membrane module is connected to the circulating water pipeline by means of the water inlet (1) and the water production hole (4), and the membrane module is connected to the drainage pipeline by means of the sewage outlet (3); the membrane module is also provided with a flushing hole (2) through which water can enter for cleaning the membrane module; and the flushing hole (2) is communicated with the water inlet (1) of the washing machine. The maintenance method for the water purification device comprises: a water purification device receives a water purifying command; control washing water to enter a membrane module; and the water purification device stops water purification after running for a cycle, and controls the washing water to enter the membrane module. The technical solution resolves the problem of cleaning of a filtration membrane module in the existing water-purifying washing machine; and furthermore, a cleaning method of the filtration membrane module is simplified, water used for cleaning the filtration membrane module is saved, and the production costs of the water-purifying washing machine are lowered.
