Control method of dish-washing machine

Abstract

The invention provides a control method of a dish-washing machine. The control method comprises the following steps: S1, detecting the oxygen concentration Q1 in the dish-washing machine before tableware is put into the dish-washing machine; S2, detecting the oxygen concentration Q2 in the dish-washing machine after the tableware is put into the dish-washing machine; S3, acquiring a first oxygen concentration difference according to the oxygen concentration Q1 and the oxygen concentration Q2; S4, enabling the dish-washing machine to enter a cleaning program; S5, after cleaning in the dish-washing machine is completed, detecting the oxygen concentration Q3 in the dish-washing machine; S6, acquiring a second oxygen concentration difference according to the oxygen concentration Q2 and the oxygen concentration Q3; and S7, controlling the dish-washing machine to perform cleaning or end a cleaning program according to the relationship between the first oxygen concentration difference and the second oxygen concentration difference. The residual state of residues before and after the dish-washing machine is cleaned is effectively detected, it is guaranteed that the residues in the dish-washing machine are cleaned up, and the situation that after the dish-washing machine finishes the cleaning program, many residues still exist in the dish-washing machine or disintegrating residues are not discharged is avoided.

Description

technical field [0001] The invention relates to the technical field of dishwashers, in particular to a control method for dishwashers. Background technique [0002] With the improvement of living standards, dishwashers are gradually becoming popular in families due to their convenient operation and superior cleaning performance. In the existing related art, after the dishwasher runs the cleaning program, although the tableware is cleaned, the food residues removed after the tableware are not cleaned up in time, which causes the inside of the dishwasher to easily generate peculiar smell, and the user does not know when the dishwasher is turned on. Know whether there are residues that have not been cleaned up and there are still odors. When the residues are not cleaned up and the odor is strong, the user will smell the odor when opening the dishwasher, resulting in poor user experience. Contents of the invention [0003] The present invention solves one of the problems exis...
