본 발명은 자동차의 디포거 구동회로에 관한 것으로, 좀더 상세하게는 자동차의 후방 유리창에 구비된 열선에 전류를 흘려서 가열함으로써 유리창에 낀 성에 등을 제거하는 자동차의 디포거 구동회로에 관한 것이다.The present invention relates to a defogger driving circuit of an automobile, and more particularly, to a defogger driving circuit of an automobile to remove frost and the like caught on the glass window by heating a current by heating the heating wire provided in the rear window of the vehicle.

일반적으로, 디포거는 자동차의 유리창에 전기 저항선을 삽입하여 유리창을 따뜻하게 함으로써 유리의 안쪽이나 바깥쪽에 붙은 서리와 얼음을 녹이는 장치를 말한다. In general, a defogger is a device that melts frost and ice on the inside or outside of a glass by inserting an electric resistance wire into a window of a car to warm the window.                         

상기 디포거 구동회로는, IG1 스위치 온되었거나 알터네이터 "L"단자의 전압을 검출하여 엔진이 작동하는 상태에서, 사용자가 리포거 스위치가 온시키면, 유리창에 구비된 열선으로 전원을 공급하여 유리창에 낀 성에 등을 제거한다.
The defogger driving circuit, when the engine is operated by detecting the voltage of the IG1 switch on or the alternator " L " Remove your back.

그러나, 상기와 같은 디포거 구동회로는, IGN1 스위치가 온된 상태에서 디포거 스위치가 온되면 열선으로 전원을 공급함에 따라 배터리가 방전되어, 이후에 엔진 시동을 걸 때 전류 부족 현상이 발생할 수 있다.However, in the defogger driving circuit as described above, when the defogger switch is turned on while the IGN1 switch is turned on, the battery is discharged as power is supplied to the hot wire, and a current shortage may occur when the engine is started later.

특히, 엔진시동과 동시에 디포거 스위치를 온하면 열선으로 전원이 공급됨에 따라 엔진 시동에 필요한 전원이 부족해질 수 있는데, 배터리 노후시에는 더욱 심각하게 발행한다.In particular, when the defogger switch is turned on at the same time as the engine is started, the power required to start the engine may be insufficient as power is supplied by a hot wire, which is more seriously issued when the battery is deteriorated.

이에, 본 발명은 상기한 바와 같은 종래의 제 문제점을 해소하기 위해 산출된 것으로, 자동차의 후방 유리창에 구비된 열선으로 전원을 공급하는 회로를 개선하여, 엔진 시동과 동시에 디포거 스위치를 온해도 엔진 시동중에는 열선으로 전원이 공급되지 않도록 하여 배터리가 다소 노후하더라도 엔진 시동에 필요한 전원을 충분히 확보할 수 있도록 하는 자동차의 디포거 구동회로를 제공하는데 그 목적이 있다.
Accordingly, the present invention has been calculated to solve the above-mentioned problems of the prior art, by improving the circuit for supplying power to the hot wire provided in the rear window of the car, even if the engine is started at the same time the defogger switch on the engine It is an object of the present invention to provide a defogger driving circuit of a vehicle that does not supply power to a hot wire during starting so that a sufficient amount of power for starting an engine can be secured even if the battery is slightly aged.

상기한 바와 같은 목적을 달성하기 위한 본 발명에 따른 자동차의 디포거 구 동회로는, IG1 전원을 제어전원으로 입력받아 스위칭온되어 IG2 전원을 공급하는 디포거릴레이와, 상기 디포거릴레이로부터 IG2 전원을 공급받아 열을 발생하여 유리창에 낀 성에를 제거하는 열선과, 사용자의 조작에 의해 온/오프되는 디포거스위치와, IG1 스위치가 "온"되었거나 알터네이터 "L"단자의 전압을 검출하여 엔진이 작동하는 상태에서 상기 디포거스위치가 온되었으면 상기 디포거릴레이의 제어전원으로 IG1 전원을 공급하는 전자제어부를 포함하여 구성된 것을 특징으로 한다.The defogger driving circuit of the vehicle according to the present invention for achieving the above object is a defogger relay for switching on by supplying IG1 power as a control power supply to supply IG2 power, and IG2 power from the defogger relay Is supplied with heat to remove frost on the window, defogger switch on / off by user's operation, IG1 switch is "on" or alternator "L" terminal detects the voltage If the defogger switch in the operating state is characterized in that it comprises an electronic control unit for supplying IG1 power to the control power of the defogger relay.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명에 따른 자동차의 디포거 구동회로의 회로도이다. 상기 도 1에 도시된 바와 같이, 본 발명에 따른 자동차의 디포거 구동회로는, 디포거릴레이(RY)와, 열선(10)과, 디포거스위치(SW)와, 전자제어부(20)를 포함하여 구성되어 있다.1 is a circuit diagram of a defogger driving circuit of a vehicle according to the present invention. As shown in FIG. 1, a defogger driving circuit of a vehicle according to the present invention includes a defogger relay RY, a heating wire 10, a defogger switch SW, and an electronic controller 20. It is composed.

상기 디포거릴레이(RY)는 전자제어부(20)의 제어에 따라 IG1 전원을 제어전원으로 입력받아 스위칭 온되어 IG2 전원을 열선(10)으로 공급하도록 되어 있다.The defogger relay RY is switched on by receiving the IG1 power as the control power under the control of the electronic controller 20 to supply the IG2 power to the heating wire 10.

상기 열선(10)은 상기 디포거릴레이(RY)로부터 IG2 전원을 공급받아 열을 발생하여 유리창에 낀 성에를 제거한다.The heating wire 10 receives IG2 power from the defogger relay RY and generates heat to remove frost on the glass window.

그리고, 상기 디포거스위치(SW)는 사용자의 조작에 의해 온/오프되어 디포거 작동여부에 대한 명령을 전자제어부(20)로 입력하도록 되어 있고, 상기 전자제어부(20)는 상기와 같이 디포거스위치(SW)가 온되었으면 상기 디포거릴레이(RY)의 제어전원 라인과 연결된 단자를 접지시켜서 상기 디포거릴레이(RY)의 제어전원으로 IG1 전원을 공급한다. In addition, the defogger switch SW is turned on / off by a user's operation to input a command for defogger operation to the electronic controller 20, and the electronic controller 20 defoggers as described above. When the switch SW is turned on, the terminal connected to the control power line of the defogger relay RY is grounded to supply IG1 power to the control power of the defogger relay RY.                     

이때, 상기 전자제어부(20)는 IG1 스위치(30)가 "온"되었거나 알터네이터(40) "L"단자의 전압을 검출하여 엔진이 작동하는 상태에서 상기 디포거스위치(SW)가 온되었을 경우에만 상기 디포거릴레이(RY)의 제어전원 라인과 연결된 단자를 접지시켜서 상기 디포거릴레이(RY)의 제어전원으로 IG1 전원을 공급시킨다.At this time, the electronic control unit 20 is only when the IG1 switch 30 is "on" or the defogger switch (SW) is turned on in the state that the engine operates by detecting the voltage of the alternator 40 "L" terminal. The terminal connected to the control power line of the defogger relay RY is grounded to supply IG1 power to the control power supply of the defogger relay RY.

상기와 같이 구성된 본 발명에 따른 자동차의 디포거 구동회로의 작용 및 효과를 상세히 설명하면 다음과 같다.Referring to the operation and effects of the defogger driving circuit of the vehicle according to the present invention configured as described above are as follows.

디포그릴레이(RY)의 코일단에 IG1 전원이 연결되어 있어, 디포그릴레이(RY)의 제어전원은 IG1이 된다.The IG1 power source is connected to the coil end of the depg Relay RY, so that the control power supply of the Depg Relay RY is IG1.

이에 반해, 디포그릴레이(RY)의 스위치단에 IG2 전원이 연결되어 있어, 차량의 후방 유리창에 구비된 열선(10)으로 공급되는 전원이 IG2 전원이 된다.On the other hand, the IG2 power source is connected to the switch terminal of the defog relay RY, so that the power supplied to the heating wire 10 provided on the rear window of the vehicle becomes the IG2 power source.

이때, 상기 IG2 전원은 엔진시동중에는 공급되지 않는 전원이므로, 엔진 시동과 동시에 디포거 스위치(SW)를 온해도 엔진 시동중에는 열선(10)으로는 전원이 공급되지 않는 것이다.
At this time, since the IG2 power is not supplied during engine start, even when the defogger switch SW is turned on at the same time as starting the engine, power is not supplied to the heating wire 10 during engine start.

이상에서 설명한 바와 같이 본 발명에 따르면, 엔진 시동과 동시에 디포거 스위치를 온해도 엔진 시동중에는 열선으로 전원이 공급되지 않도록 하여 배터리가 다소 노후하더라도 엔진 시동에 필요한 전원을 충분히 확보할 수 있도록 하는 효과가 있다.
As described above, according to the present invention, even if the defogger switch is turned on at the same time as the engine is started, the power is not supplied to the hot wire during the engine is started, so that the power required to start the engine is sufficiently secured even if the battery is slightly aged. have.
