Auto-wash control method and device of dishwasher and dishwasher

Abstract

The invention discloses an auto-wash control method and device of a dishwasher and a dishwasher, wherein the auto-wash control method comprises: after initial water intake of the dishwasher is under control and washing is carried out for a first preset time, detecting turbidity of washing water in the dishwasher to obtain a first turbidity signal value; judging a turbidity range at the first turbidity signal value to obtain contamination degree of dishware in the dishwasher, with the contamination degree of the dishware including light contamination, medium contamination and serious contamination; when the contamination degree of the dishware is serious contamination, controlling water re-intake of the dishwasher so that the dishwasher carries rewashing at least once; detecting turbidity of washing water in the dishwasher after the dishwasher carries out rewashing to obtain a second turbidity signal value, and acquiring a washing path of the dishwasher according to the second turbidity signal value to control the dishwasher to run according to the acquired washing path. The method improves recognition precision of the contamination degree of dishware, thus improving the accuracy of the washing path and improving user satisfaction.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to an automatic washing control method and device for a dishwasher and the dishwasher. Background technique [0002] In order to save users from the trouble of choosing a washing program, more and more dishwashers provide a washing program called "Auto", which uses a turbidity sensor that can detect the degree of dirt in the water. Since the testing agency has divided the automatic washing into four pollution levels: 0%, 50%, 100% and 150%, the general algorithm of the existing dishwasher automatic washing program is to divide four turbidity value intervals, corresponding to the above-mentioned The four pollution levels represent the different degrees of soiling of the dishes in the dishwasher. After the dishwasher enters the water for the first time, wash it for a period of time to wash off the dirt on the tableware, then detect the turbidity of the water through the...

AI Technical Summary

Problems solved by technology

For this reason, an object of the present invention is to propose an automatic washing control method for dishwashers. The automatic washing control method improves the resolution accuracy of tableware pollution levels, further improves the accuracy of the washing path, and solves the problems in related technologies. Dishwashers confuse the pollution level of tableware, resulting in incomplete washing or waste of water and electricity resources, which greatly improves the experience of using dishwashers, thereby improving user satisfaction
