Abstract

본 발명은 세탁 수행시 헹굼 행정에서 세탁물이 엉켜 부하가 커질 때 펄세이터를 좌우로 교반시켜 세탁물을 풀어줄 수 있게 하는 세탁기의 세탁물 엉킴방지회로에 관한 것으로 기존의 마이컴, 모터구동제어부(2), 런닝 커패시터(3), 펄스검출부(5)로 된 구성에서 메모리된 초기 데이타값과 헹굼 행정시 체크한 데이타를 비교하여 비교치가 같으면 계속 헹굼 행정을 실시하고, 비교치가 다르면 펄세이터를 좌, 우로 짧은 시간 간격으로 교반시키도록 제어하는 프로그램을 가진 마이컴(1)을 구비하여 이 마이컴(1)의 제어에 의해 세탁물이 엉켜 있을 때 펄세이터를 좌우로 교반시켜 약한 물살을 일으키게 함으로 세탁물의 엉킴을 방지하도록 한 것이다.The present invention relates to a laundry tangling prevention circuit of a washing machine that can release the laundry by stirring the pulsator from side to side when the load is entangled in the rinsing stroke during the washing, the conventional microcomputer, motor drive control unit (2), running In the configuration consisting of the capacitor (3) and the pulse detector (5), the initial data value memorized and the data checked during the rinsing stroke are compared. If the comparison value is the same, the rinsing stroke is continuously performed. If the comparison value is different, the pulsator is left and right for a short time. A microcomputer (1) having a program for controlling the stirring at intervals is provided, and when the laundry is tangled by the control of the microcomputer (1), the pulsator is stirred from side to side to cause weak water to prevent tangling of the laundry. will be.
