Abstract

본 발명은 세탁기의 배수제어장치 및 방법에 관한 것으로, 종래에는 셋수위보다 낮은 수위(P4)는 수두가 낮아 세탁조 하부 일측벽에 형성된 에어챔버내에 충분한 압력을 발생시키지 못하므로 수위센서로 전달되는 공기압이 약해 수위센서내부의 다이아그램을 밀어올리지 못함에 따라 수위센서가 세탁조내의 수위를 정확히 감지할 수 없어서 리셋수위까지 배수됨이 감지되면 그 이후에는 리셋수위 이하의 세탁수가 충분히 배수될 수 있을 만큼의 미리설정된 넉넉한 시간동안 배수토록 하는데 실제로 완전배수가 다 되었는데 설정된 시간이 도달하지 않으면 바로 다음 행정으로 넘어가지 못하고 설정시간이 다 될때까지 기다려야 하므로 시간낭비가 많은 문제점이 있다. 따라서 본 발명은 온도센서를 이용하여 배수관내의 온도를 감지하여 배수완료시점을 빠른 시간내에 찾아내어 바로 다음 행정을 넘어갈 수 있으므로 배수시간이 단축됨으로써 세탁에 소요되는 전체시간을 단축하고, 전기를 절약할 수 있도록 한다.The present invention relates to a drainage control apparatus and method of a washing machine, and conventionally, the water level (P4) lower than the set water level has a low head so that it does not generate sufficient pressure in the air chamber formed on one side wall of the lower part of the washing tank, the air pressure delivered to the water level sensor If the water level sensor cannot detect the water level in the washing tank and is drained to the reset water level because the diagram inside the water level sensor cannot be pushed up, the water level below the reset water level can be drained after that. There is a problem in that it is a waste of time because the water is drained for a predetermined time, but when the set time is not reached, it does not go to the next stroke and waits until the set time is reached. Therefore, the present invention can detect the temperature in the drain pipe by using a temperature sensor to find the time of completion of drainage within a short time to go immediately to the next stroke, so that the drainage time is shortened, reducing the overall time required for washing, save electricity To help.
