Abstract

본 발명은 세탁기의 탈수 제어방법 및 그 장치에 관한 것으로, 종래에는 세탁물의 탈수시 모터 구동시간이 제한적으로 설정되어 있어 비산음 상태에서 모터가 구동되어 소음이 발생될 뿐아니라 모터의 온도가 급격히 상승됨으로써 탈수시간이 길어지고 탈수효율이 저하되는 문제점이 있었다.The present invention relates to a method for controlling dehydration of a washing machine and a device thereof, and in the related art, the motor driving time is limited when the laundry is dewatered, so that the motor is driven in a scattering state and noise is generated as well. As a result, the dehydration time becomes longer and the dehydration efficiency is lowered.

이러한 점을 감안하여 본 발명에서는 세탁물 탈수시 배수가 끝나 일정시간이 경과하면 모터를 온시켜 저속으로 구동함으로써 세탁물에 함유된 물을 제거하고 이에따라 모터의 회전속도를 점차로 증가시켜 고속으로 소정시간 유지시킴으로써 비산음 상태를 제거하여 소음을 방지하고 모터의 급격한 온도상승을 방지하여 탈수 효율을 증대시킨다.In view of this point, in the present invention, when the laundry is dewatered and drained after a predetermined time, the motor is turned on and driven at a low speed to remove water contained in the laundry, thereby gradually increasing the rotational speed of the motor to maintain a predetermined time at a high speed. Eliminates scattered noise to prevent noise and prevents rapid temperature rise of the motor to increase dewatering efficiency.
