Abstract
본 발명은 세탁기의 포량감지 및 수위설정방법에 관한 것으로, 종래에는 같은 포량일지라도 세탁조내의 포상태에 따라 모터의 여러 펄스수 차이가 많이 발생하여 포량감지시 에러가 발생되고 항상 물을 포량감지 설정수위까지 급수하게되어 전체 세탁시간이 많이 소비되었다.The present invention relates to a quantity detection method and a water level setting method of a washing machine. Conventionally, even if the same amount of water, various pulse number differences of the motor occur depending on the state of the laundry in the washing tank. Since the water was supplied until the entire washing time was consumed a lot.
따라서 종래의 문제점을 해결하기 위하여 본 발명은 포량감지시 공수위 상태에서 모터 온/오프시의 펄스수와 모터온시의 전류값을 조합하여 포량을 감지하고, 사용자가 수동조작으로 수위를 설정했을 때 모터의 FG 신호를 이용하고 포량을 감지한 후 수위를 결정함으로써 세탁진행에 따른 포손상 및 세탁성능 저하를 사전에 방지할 수 있도록 한 효과가 있다.Therefore, in order to solve the conventional problems, the present invention detects a quantity of air by combining the number of pulses at the time of motor on / off and the current value at the time of motor in the airborne state when the quantity of water is detected, and the user sets the water level by manual operation. When the FG signal of the motor is used and the amount of water is detected and the water level is determined, it is possible to prevent the damage and deterioration of washing performance due to the washing process in advance.
