전자동 세탁기의 냉온수 밸브 제어방법

Abstract

본 발명은 전자동 세탁기에 관한 것으로, 특히 전자동 세탁기에서 세탁이나 헹굼을 하기 위해 물을 입수할 때, 정확한 세탁수의 온도를 맞추기 위해, 냉수 및 온수 밸브의 개폐를 비례미분 방식을 이용하여 세탁수 온도를 정확하게 제어할 수 있는 전자동 세탁기의 냉온수 밸브 제어 방법을 제공한다.
PURPOSE: A control method for cool/hot water valves of a fully automated washing machine is provided to precisely control temperature of water by controlling a single control variable. CONSTITUTION: A control method for cool/hot water valves of a fully automated washing machine includes the steps of supplying cool water to a washing tub(S11), blocking the cool water supply when the cool water in the washing tub reaches a predetermined water level(S12), supplying hot water to the washing tub(S13), blocking the hot water supply when the temperature of the supplied water in the washing tub reaches a predetermined temperature(S14), supplying hot and cool water to the washing tub under the proportional and derivative control(S15), and blocking the hot and cool water supply if the water level reaches a target point(S16).
