Abstract
본 발명은 세탁기의 배수펌프 구동제어장치 및 방법에 관한 것으로서, 특히 배수펌프가 부착된 강제 배수형 전기세탁기의 배수펌프 케이싱(cashing)내에 배수할 세탁수의 유무를 판단하여 상기 배수펌프의 동작 및 차단을 제어하는 세탁기의 배수펌프 구동장치 및 그 제어방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage pump driving control apparatus and method for a washing machine, and more particularly, to determine the presence or absence of wash water to be drained in a drainage pump casing of a forced drain type electric washing machine equipped with a drainage pump. The present invention relates to a drainage pump driving apparatus for controlling a shutoff and a control method thereof.
이러한 세탁기의 배수펌프 구동장치 및 그 제어는 제어부에서 신호가 입력되면 배수펌프의 동작으로 재설정 수위를 감지하는 제1단계와, 상기 제1단계에서 재설정수위가 감지되면 소부하부의 양단전압(V1)을 상기 전압 감지부에서 감지하고, 상기 배수펌프의 동작으로 세탁조내의 세탁수를 완전히 배출시키는 제2단계와, 상기 제2단계에서 세탁수가 완전히 배수되면 탈수전동기가 동작함과 동시에 이때 전압감지부에서 상기 소부하부의 양단 전압(V2)을 감지하여 상기 소부하부의 양단전압 V1과 V2를 비교하는 제3단계와, 상기 제3단계에서 소부하부의 양단전압 V1이 V2보다 클경우 상기 배수펌프를 차단하고, 상기 제어부에 설정된 배수 및 차단시간이 지나면 상기 탈수전동기 및 배수펌프를 차단하는 단계에 의해 달성된다. 따라서, 이러한 배수펌프구동장치 및 그 제어방법은 절전형 세탁기에 유용하게 적용된다.The drainage pump driving device of the washing machine and its control are the first step of detecting the reset water level by the operation of the drainage pump when a signal is input from the controller, and the voltage at both ends of the small load (V 1) when the reset water level is detected in the first step. ) Is detected by the voltage sensing unit, and the second step of completely discharging the washing water in the washing tank by the operation of the drainage pump, and when the washing water is completely drained in the second step, the dehydration motor is operated and at this time the voltage detecting unit Senses the voltage across both ends of the small load (V 2 ) at step 3 and compares the voltage between both ends of the small load V 1 and V 2 , and at the third step, the voltage between both ends of the small load V 1 is greater than V 2. When the drainage pump is blocked, and the drainage and cutoff time set in the control unit is achieved by the step of blocking the dehydration motor and the drainage pump. Therefore, such a drain pump driving device and a control method thereof are usefully applied to a power saving washing machine.
