Abstract

본 발명은 전자동 세탁기의 안전스위치에 관한 것이다. 구체적으로는 세탁기의 저수조가 탈수 행정시에 비정상적으로 요동하는 경우에 세탁조의 회전을 중단시키는 역할을 하는 세탁기의 안전스위치에 관한 것이다. 특히, 본 발명은 저수조의 하부면에 설치되어 세탁물의 언발란스를 감지하여 작동하는 전도형의 안전스위치에 관한 것이다.The present invention relates to a safety switch of a fully automatic washing machine. More particularly, the present invention relates to a safety switch of a washing machine, which serves to stop the rotation of the washing tank in the case where the water storage tank of the washing machine is abnormally shaken during the dehydration stroke. In particular, the present invention relates to a safety type switch of the conductive type installed on the lower surface of the water tank to operate by sensing the unbalance of the laundry.

본 발명은 세탁기의 언발란스 감지용 안전스위치는, 내부에 한 쌍의 접속편이 설치되어 있으며, 그 사이에서 이동가능한 전도성 수은이 삽입된 전도형 안전스위치를 저수조의 하부 외측 바닥면에 부착하였으며, 상기 안전스위치의 일단부는 주제어기판의 제어용 마이컴에 연결되고 타단부는 전동기에 접속된 것을 특징으로 한다.According to the present invention, a safety switch for detecting an unbalance of a washing machine has a pair of connecting pieces installed therein, and a conductive safety switch having conductive mercury inserted therein is attached to a lower outer bottom surface of the water tank. One end of the switch is connected to the control microcomputer of the main controller and the other end is connected to the motor.
