Abstract

본 발명은 자동차 리어윈도우 디포거글래스(9)에 형성된 열선(10)에 배터리 전원을 공급하여 가열하기 위해 점화키스위치(SW1)의 점화단지에 연결된 디포거 스위치(SW2)와 디포거릴레이 RY를 구비한 통상의 리어윈도우 열선 전원공급회로에서 열선(10)의 일 끝단에 정온저항소자(TH)를 직렬연결하여 구성되고 이 정온저항소자의 큐리 온도값이 상기 열선(10)의 최고가열온도값에 대응되도록 설정된 리어윈도우 열선의 과열방지장치에 관한 것이다. 이 정온저항소자는 BaTiO3 산화물에 TiO2, CeO 등을 일정량 첨가하여 소결함으로써 소정의 큐리 온도를 갖게 만드는 것을 특징으로 한다. 본 발명에 의하면 별도의 타이머 없이도 열선의 과열을 방지하고 열선의 소비전류값을 낮출 수 있는 장점이 있다.The present invention provides a defogger relay RY connected to a defogger switch SW2 connected to an ignition stage of the ignition key switch SW1 for heating and supplying battery power to the heating wire 10 formed in the vehicle rear window defogger glass 9. In a conventional rear window heat wire power supply circuit, a constant temperature resistance element (TH) is connected in series at one end of the heat wire (10), and the Curie temperature value of the constant temperature resistance element is the highest heating temperature value of the heat wire (10). The overwind prevention device of the rear window heating wire set to correspond to. The constant temperature resistive element is characterized by having a predetermined Curie temperature by adding a predetermined amount of TiO 2, CeO, and the like to BaTiO 3 oxide. According to the present invention, there is an advantage of preventing overheating of the heating wire and lowering the current consumption value of the heating wire without a separate timer.
