WASHING METHOD OF WASHING MACHINE TO IMPROVE WASHING EFFICIENCY AND RINSING EFFICIENCY BY RESETTING SUPPLY WATER LEVEL AND WASHING PATTERN CONSIDERING DETERGENT AMOUNT IN WASHING GRADUALLY

摘要

PURPOSE: A washing method of a washing machine is provided to wash and rinse the laundry efficiently, and to reduce water and energy consumption by accurately calculating the detergent amount dissolved sufficiently in washing water and optimally setting washing pattern. CONSTITUTION: The hardness of washing water measured in washing is loaded in turning on the washing machine, and the water level and the washing pattern are set according to the laundry amount and the hardness of washing water(S1,S2). Detergent is dissolved in supplying water to the first predetermined water level(S3). The amount of detergent dissolved in washing water is measured for the predetermined time(S4,S5). The second water level and the third water level are reset according to the measured detergent amount, and washing is performed at the first predetermined water level(S6,S7). Washing is performed according to the washing pattern in supplying water to the second predetermined water level, and according to the reset washing pattern in supplying water to the third predetermined water level(S8,S9). Rinsing is performed after finishing washing(S10). The hardness of washing water is measured and stored before finishing the final rinsing course, and the dehydration course is performed in finishing rinsing(S11,S12).
