DECIDING METHOD OF WASHING COURSE FOR WASHING MACHINE

摘要

PURPOSE: A washing course deciding method for a washing machine is provided to operate a washing stroke in an optimum washing pattern by deciding the amount of detergent with temperature and conductivity of washing water. CONSTITUTION: Washing water and detergent are inputted to submerge a temperature sensor and an electrode sensor installed to side of a washing tub(S1). Water temperature is measured by the temperature sensor(S2). A regression formula is set according to measured temperature(S3). Conductivity of washing water is measured by the electrode sensor(S4). The amount of detergent is decided by the regression formula according to measured conductivity(S5). A washing pattern is set the decided amount of detergent(S6). A washing operation is operated by the set washing pattern(S7). Thereby, washing efficiency is improved and time and water are reduced by operating the washing operation in an optimum washing pattern.
