Abstract The present invention relates to a method for controlling a laundry treatment apparatus, to reduce a frequency of water hammering noise during a process for washing a filter and a heat exchanger. According to the present invention, the laundry treatment apparatus comprises: a drum rotationally disposed in a tub to receive laundry; the heat exchanger exchanging heat between air flow and a refrigerant on a circulation path circulating air discharged from the tub therethrough; the filter filtering the air flow; a first washing device supplying washing water to one from the filter and the heat exchanger; and a second washing device supplying the washing water to the other one from the filter and the heat exchanger. The method comprises: a flow rate measurement step of measuring a flow rate while supplying water into the tub; and a washing step of controlling, based on the flow rate, a first flow path control valve controlling water supply to the first washing device and a second flow path control valve controlling water supply to the second washing device. When the flow rate is less than a preset reference flow rate, the washing step performs a low pressure washing mode of repeating opening/closing of the first flow path control valve for a plurality of times and repeating opening/closing of the second flow path control valve for a plurality of times. When the flow rate is equal to or greater than the preset reference flow rate, the washing step performs a high pressure washing mode of closing the first flow path control valve after the opening of the same for a preset first time and closing the second flow path control valve after the opening of the same for a preset second time. 본 발명은, 의류를 수용하는 드럼이 터브 내에 회전 가능하게 배치되고, 상기 터브로부터 배출된 공기가 순환되는 순환유로 상에 기류와 냉매를 열교환시키는 열교환기가 구비되고, 상기 기류를 여과하는 필터와, 상기 필터 및 열교환기 중 어느 하나에 세척수를 가하는 제 1 세척기구와, 상기 필터 및 열교환기 중 다른 하나에 세척수를 가하는 제 2 세척기구를 구비한 세탁물 처리장치의 제어방법에 관한 것으로써, 상기 터브 내로 급수를 하면서 유량을 측정하는 유량측정단계와, 상기 유량을 바탕으로, 상기 제 1 세척기구로의 급수를 단속하는 제 1 유로단속밸브와 상기 제 2 세척기구로의 급수를 단속하는 제 2 유로단속밸브를 제어하는 세척단계를 포함하고, 상기 세척단계는 상기 유량이 기 설정된 기준유량 미만이면, 상기 제 1 유로단속밸브의 개폐를 복수회 반복한 후 상기 제 2 유로단속밸브의 개폐를 복수회 반복하는 저압세척모드를 실시하고, 상기 유량이 기 설정된 기준유량 이상이면, 상기 제 1 유로단속밸브를 기 설정된 제 1 시간 동안 개방시켰다가 폐쇄한 후, 상기 제 2 유로단속밸브를 기 설정된 제 2 시간 동안 개방시켰다가 폐쇄하는 고압세척모드를 실시한다.
AbstractList The present invention relates to a method for controlling a laundry treatment apparatus, to reduce a frequency of water hammering noise during a process for washing a filter and a heat exchanger. According to the present invention, the laundry treatment apparatus comprises: a drum rotationally disposed in a tub to receive laundry; the heat exchanger exchanging heat between air flow and a refrigerant on a circulation path circulating air discharged from the tub therethrough; the filter filtering the air flow; a first washing device supplying washing water to one from the filter and the heat exchanger; and a second washing device supplying the washing water to the other one from the filter and the heat exchanger.
