Abstract

본 발명은 세탁시 모터의 정역회전구동에 의하여, 정역 회전하면서 세탁 및 헹굼을 하게 되는 펄세이터의 회전시간으로 펄세이터의 구속 여부상태를 감지할 수 있도록 한 세탁기의 펄세이터 구속감지방법에 관한 것으로, 본 발명은 모터를 구동하여 세탁을 하는 단계와, 상기 단계에서 모터의 구동에 의하여 정역회전하는 펄세이터의 인닥던스변화로 회전시간을 감지하는 단계와, 상기 단계에서 감지된 회전시간이 일정한가를 판단하는 단계와, 상기 단계에서 판단결과 회전시간이 일정하면 정상동작을 하는 단계와, 상기 단계에서 판단결과 회전시간이 일정하지 않을 경우, 이 일정하지 않는 회전시간이 소정의 설정시간을 경과하였는가 판단하는 단계와, 상기 단계에서 소정의 설정시간이 경과하였으면 펄세이터가 구속된 것으로 판단하여 펄세이터의 회전을 짧게 좌,우 회전시키면 펄세이터구속을 해제하는 단계로 이루어짐을 특징으로 한다.The present invention relates to a pulsator restraint detection method of a washing machine capable of detecting whether a pulsator is restrained by a rotation time of a pulsator that is washed and rinsed while washing and rinsing while performing forward and reverse rotation of a motor during washing. The present invention includes the steps of washing the driving of the motor, the step of detecting the rotation time by the change in the inductance of the pulsator forward and reverse rotation by the drive of the motor in the step, and whether the rotation time detected in the step is constant Determining, and if the rotation time is constant as determined in the step, performing normal operation; and if the rotation time is not constant as determined in the step, determining whether the non-uniform rotation time has passed a predetermined set time. And the pulsator is determined that the pulsator is constrained if the predetermined time has elapsed in the step. If a shorter rotation left, right rotation is characterized by made of an step of releasing a pulsator bound.
