Dish washing machine and washing control method and device thereof

Abstract

The invention belongs to the technical field of control of tableware washing, and provides a dish washing machine and washing control method and device of the dish washing machine. The method is that the subsequent washing modes are accurately selected in the turbidity calibration stage, the pre-washing stage and the main washing stage of the dish washing machine according to the detected turbidity value; the fault and abnormality of a turbidity sensor is determined at the turbidity calibration and the pre-washing stage according to the detected turbidity value; in case of fault and abnormality in the turbidity sensor, the dish washing machine is controlled to work by an abnormal washing mode in the main washing stage and the abnormal washing mode at a rinsing stage; the fault and abnormality of the turbidity sensor are determined at the main washing stage according to the detected turbidity value. According to the method, the dish washing machine is controlled to automatically work by the abnormal washing mode in the rinsing stage in case of fault and abnormality in the turbidity sensor, so that the problems that the turbidity is easily inaccurately determined to cause that dish washing machine cannot adaptively wash tableware, and the dish washing machine is failed to wash in case of fault and abnormality in the turbidity sensor, can be solved.

Description

technical field [0001] The invention belongs to the technical field of tableware washing control, and in particular relates to a dishwasher and a washing control method and device thereof. Background technique [0002] At present, a turbidity sensor that detects the turbidity of water is usually installed in a dishwasher. During operation, the dishwasher can judge the degree of pollution of the tableware through the turbidity value detected by the turbidity sensor, and according to the degree of pollution of the tableware The degree of pollution automatically selects the washing mode and the corresponding control parameters, so as to achieve the purpose of self-adaptive washing operation for the tableware according to the degree of pollution of the tableware. However, in the dishwasher washing control method provided by the prior art, because the processing method of the turbidity signal fed back by the turbidity sensor is unstable, and the setting of the washing method is u...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a washing control method for dishwashers, which aims to solve the problem in the prior art that the turbidity judgment is easy to make mistakes, which leads to the inability to realize the self-adaptive washing operation on the tableware, and when the turbidity sensor malfunctions abnormally, it will cause The problem that the dishwasher cannot complete the washing process by itself
