Cyclic spray control method and washing machine

Abstract

The invention belongs to the washing machine field and especially relates to a cyclic spray control method and a washing machine. The washing machine comprises an inner cylinder, an outer cylinder anda cyclic spray system. The cyclic spray system cyclically sprays washing water to the inner cylinder and/or the outer cylinder to scour and wash the inner wall of the inner cylinder and/or the outercylinder. The control method comprises the following steps that the washing machine makes the cyclic spray system start; the washing water is cyclically sprayed to the inner cylinder and/or the outercylinder; and the inner wall of the inner cylinder and/or the outer cylinder is scoured and washed. The method and the washing machine have advantages that the cleaner washing water after clothes washing is used to wash the dirty areas of the cylinder wall of the inner cylinder and/or the inner wall of the outer cylinder of the washing machine, cost is reduced, water resource wastes are decreased,and environmental protection performance is achieved; and through arranging a detection unit used for detecting the turbidity value of the washing water, according to the detected turbidity value ofthe washing water, the cyclic spray system is controlled to be started, and control precision is high and reasonable.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to a cycle spray control method and a washing machine. Background technique [0002] When the drum washing machine is washing and rinsing, due to gaps, angles of water flow, etc., after the laundry is finished, there are still detergent foams, lint, etc. attached to the observation window and the window gasket sealing ring, which cannot be rinsed clean. Due to the existence of foam and residual detergent, the washing effect is seriously affected, and it is easy to recontaminate the clothes when they are taken out, and the lint and sand left after washing are easy to accumulate in the side wall and folds of the window gasket sealing ring, which is easy to cause The growth of bacteria will affect the washing effect and healthy life. [0003] At present, various washing machine manufacturers have taken various measures to eliminate the foam and clean the remaining detergent...

AI Technical Summary

Problems solved by technology

At present, it is mainly used to introduce external water such as tap water for spraying to remove dirt or foam on the inner wall of the inner tub or the outer tub. However, during the washing process, if the clothes are not very dirty or after multiple rinses, the washing water and tap water The ingredients are basically the same. If the external water is used as the spray water and the laundry water is discharged, it will easily cause waste of water resources, and it is necessary to install external equipment, which will also increase the cost.
