Abstract
본 발명은 세탁시 구동하는 세탁모터의 전류 상태에 따라 펄스를 발생하고 이 발생된 펄스를 소정의 기준펄스와 연산하여 과전류상태를 감지할 수 있도록 한 세탁기의 세탁모터 과전류감지장치에 관한 것으로, 본 발명은 세탁시 구동하는 세탁모터의 파워모듈에 흐르는 전류상태를 감지하는 감지수단과, 상기 감지수단에 의하여 감지된 전류를 소정의 시정수를 갖고 지연하여 단펄스를 출력하는 단펄스출력수단과, 상기 단펄스출력수단에서 발생되는 단펄스와 소정의 기준펄스와를 연산하고 이 연산된 펄스에 의하여 세탁모터의 구동을 제어하는 제어수단으로 구성됨을 특징으로 한다.The present invention relates to a washing motor overcurrent detection device of a washing machine that generates a pulse according to a current state of a washing motor driven during washing, and calculates the generated pulse with a predetermined reference pulse to detect an overcurrent state. According to the present invention, there is provided a sensing means for sensing a current state flowing through a power module of a washing motor driven during washing, short pulse output means for outputting a short pulse by delaying a current sensed by the sensing means with a predetermined time constant; And a control means for calculating the short pulse generated by the short pulse output means and a predetermined reference pulse and controlling the driving of the washing motor by the calculated pulse.
