DEVICE AND METHOD FOR CONTROLLING TEMPERATURE OF WASHING WATER AT EARLY POWER INPUT IN DISH WASHER

摘要

PURPOSE: A device and a method for controlling a temperature of washing water are provided to improve the washing efficiency at an initial washing and to prevent unnecessary power consumption. CONSTITUTION: A microcomputer(7) contains a rinsing water temperature discriminating unit(71); a washing water level discriminating unit(72); a rinsing water level discriminating unit(73); a timer(74); a washing water temperature control unit(75); a rinsing pump driving command unit(76); a hydroelectric valve driving command unit(77); and a booster driving command unit(78). A water level of rinsing water is detected. The rising water is supplemented and a booster is driven by turning on a hydroelectric valve when the rinsing water is not filled enough. Otherwise, a state of the hydroelectric valve is detected. In turning on the hydroelectric valve, the hydroelectric valve is turned off. In turning off the hydroelectric valve, a temperature of the rinsing water is detected. The booster is operated continuously until the temperature of the rising water reaches a specific temperature. The heated rinsing water is inserted into a washing tub.
