COURSE CONTROL METHOD BY TURBIDITY OF A DISHWASHER FOR IMPROVING THE WASHING PERFORMANCE AND RELIABILITY THROUGH EXACT POLLUTION LEVEL DETECTION OF WASH WATER

摘要

PURPOSE: A course control method by the turbidity of a dishwasher is provided to compensate for a turbidity detection error caused by clearance of a turbidity sensor. CONSTITUTION: A course control method by the turbidity of a dishwasher comprises supplying wash water to a predetermined water level according to a user's wash command(S10,S20); detecting first turbidity of wash water supplied at a point of time when water supply to the predetermined water level is completed, and executing preliminary wash(S30,S40); detecting second turbidity of wash water circulating in the process of executing preliminary wash(S50); and controlling a wash stroke according to a difference value of the first turbidity and the second turbidity(S60¯S81).
