본 발명은 자동차의 창문 서리 자동 제거에 관한 것으로, 특히 뒷 창문에 발생되는 서리를 감지하고 자동으로 열선을 작동시켜 발생된 서리를 제거하도록 한 자동차의 창문 서리 자동 제거장치에 관한 것이다.The present invention relates to automatic window frost removal of a vehicle, and more particularly, to an automatic window frost removal apparatus for detecting the frost generated in the rear window and automatically operating a heating wire to remove the frost generated.

종래의 자동차에 있어서, 뒷 창문에 발생된 서리 제거 방법은 운전자가 뒤창문을 시각적으로 학인하여 서리가 발생된것으로 판단되면 열선동작 스위치를 수동조작하여 온시킨다.In the conventional vehicle, the method of removing frost generated in the rear window turns on by manually operating the hot wire operation switch when the driver visually recognizes the rear window and determines that the frost is generated.

열선동작 스위치가 온되면 열선에는 구동전원이 공급되어 발열이 되고, 그 발열에 의한 열원으로 서리를 제거하게 된다.When the hot wire operation switch is turned on, the driving power is supplied to the hot wire to generate heat, and the frost is removed as a heat source by the heat generation.

그러나 이러한 종래의 서리 제거장치는 운전자가 서리가 발생된것을 확인하고 수동조작으로 열선동작 스위치를 조작하여야만 열선이 발열되어 서리제거가 가능하므로 수동조작에 의한 불편함이 따르는 문제점이 있었다.However, such a conventional defroster has a problem in that the driver has to check that frost is generated and operate the hot wire operation switch by manual operation so that the heating wire is defrosted and the frost can be removed.

따라서 본 발명은 상기와 같은 종래 기술의 제반 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 뒷 창문에 발생되는 서리를 감지하고 자동으로 열선을 작동시켜 발생된 서리를 제거하도록 자동차의 창문 서리 자동 제거장치를 제공하는데 있다.Therefore, the present invention is to solve the problems of the prior art as described above, an object of the present invention is to detect the frost generated in the rear window and to automatically remove the frost generated by operating the heating wire to automatically remove the window frost To provide a device.

이러한 본 발명의 목적을 달성하기 위한 기술적 수단은 광을 발생하고 뒷창문을 서리 발생 여부에 따라 뒷 창문으로 투과되는 광을 수광하여 서리 감지값으로 출력하는 서리 감지수단과, 상기 서리 감지수단에서 출력되는 서리 감지값에 따라 열선 제어신호를 발생시키는 열선 제어수단과, 상기 열선 제어수단에서 출력되는 신호에 의해 열선을 발열시켜 서리를 제거하는 열선 구동수단으로 이루어진다.Technical means for achieving the object of the present invention is a frost detection means for generating light and receiving the light transmitted to the rear window according to whether or not frost occurs, and outputs the frost detection value, and output from the frost detection means The hot wire control means for generating a hot wire control signal according to the frost detection value, and the hot wire driving means for generating frost by heating the hot wire by the signal output from the hot wire control means.

이하, 본 발명을 첨부한 도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings of the present invention.

제1도는 본 발명에 의한 서리 감지부의 장착위치를 설명하기 위한 사시도로서, 도시된 바와 같이 자동차의 뒷 창문(1)의 하단부에 설치되고, 차량 내부에는 광을 발생시키는 발광부(2a)가 구비되고, 차량 외부에는 발광부(2a)에서 발광된 광을 서리 유무에 따라 수광하기 위한 수광부(2b)가 구비 되었다.1 is a perspective view for explaining a mounting position of the frost detection unit according to the present invention, which is installed in the lower end of the rear window (1) of the vehicle as shown, the light emitting unit (2a) for generating light inside the vehicle is provided On the outside of the vehicle, a light receiving unit 2b for receiving light emitted from the light emitting unit 2a according to the presence or absence of frost is provided.

제2도는 본 발명에 의한 창문 서리 자동 제거장치 구성도이다.2 is a block diagram of the automatic window frost removal device according to the present invention.

도시된 바와 같이, 광을 발생하고 뒷창문의 서리 발생 여부에 따라 투과되는 광을 수신하여 서리 감지값으로 출력하는 서리 감지부(2)가 뒷 창문(1)의 하단부에 장착되고, 상기 서리 감지부(2)내의 수광부(2b)에서 출력되는 광 감지값에 따라 열선 제어신호를 발생시키는 열선 제어부(3)가 수광부(2b)에 연결되며, 상기 열선 제어부(3)에는 열선 제어신호에 의해 열선을 구동시키는 열선 구동부(4)가 연결되어 구성 된다.As shown, a frost detection unit 2 for generating light and receiving light transmitted according to whether or not frost of the rear window is generated and outputting it as a frost detection value is mounted at the lower end of the rear window 1, and the frost detection A heating wire control unit 3 for generating a heating wire control signal according to the light sensing value output from the light receiving unit 2b in the unit 2 is connected to the light receiving unit 2b, and the heating wire control unit 3 is connected to the heating wire by a heating wire control signal. It is configured to connect the hot wire drive unit 4 for driving.

이와 같이 구성된 본 발명에 의한 창문 서리 자동 제거장치의 작용 및 효과를 첨부한 도면 제3도를 참조하여 설명하면 다음과 같다.The operation and effects of the automatic window frost removing apparatus according to the present invention configured as described above will be described with reference to FIG. 3.

먼저, 자동차의 시동이 온되면 서리 감지부(2)내의 발광부(2a)는 공급되는 전원으로 포토다이오드(PD)가 발광을 하여 광을 송출시키게 된다.First, when the vehicle is turned on, the light emitting unit 2a in the frost sensing unit 2 emits light by emitting light from the photodiode PD using the supplied power.

송출되는 광은 뒷 창문(1)의 서리 발생 여부에 따라 투과 또는 차단되는데, 이때 수광부(2b)는 차량 밖에 설치되어 뒷 창문(1)으로 투과되는 광에 따라 포토트랜지스터(PT)가 온 또는 오프되고, 포토트랜지스터(PT)의 온 또는 오프에 의해 연산증폭기(OP1)의 출력전압(VO)이 달라져 서리 발생을 감지하게 된다.The transmitted light is transmitted or blocked depending on whether frost of the rear window 1 is generated. In this case, the light receiving unit 2b is installed outside the vehicle and the phototransistor PT is turned on or off according to the light transmitted to the rear window 1. The output voltage VO of the operational amplifier OP1 is changed by turning on or off the phototransistor PT to detect the occurrence of frost.

즉, 뒷 창문(1)에 서리가 있는 경우에는 포토다이오드(PD)에서 발광된 광이 차단되어 수광부(2b)에 수광되는 광량이 없어 포토트랜지스터(PT)가 오프되고, 이로인해 연산증폭기(OP1)의 출력전압(Vo)은 OV가 되어 열선 제어부(3)에 입력된다.That is, when there is frost in the rear window 1, the light emitted from the photodiode PD is blocked and there is no light received by the light receiving unit 2b, so that the phototransistor PT is turned off, thereby causing the operational amplifier OP1. Output voltage Vo becomes OV and is input to the heating wire control unit 3.

열선 제어부(3)는 입력되는 저전위(OV)에 의해 트랜지스터(TR1)가 오프되며, 트랜지스터(TR1)의 오프에 의해 릴레이(RY)도 오프되어 열선 구동부(4)는 구동을 하게된다.The transistor TR1 is turned off by the input low potential OV, and the relay RY is also turned off by turning off the transistor TR1, so that the heater wire driver 4 is driven.

열선 구동부(4)의 구동에 의해 열선(도면에는 미도시)에는 발열 전원이 공급되어 발열을 하게되고, 그 열원에 의해 뒷 창문(1)에 발생된 서리는 제거된다.The heating wire (not shown in the figure) is supplied with heat generating power to generate heat by driving the heating wire drive unit 4, and the frost generated in the rear window 1 is removed by the heat source.

다음으로 뒷 창문(1)에 서리가 없는 경우에는 포토다이오드(PD)에서 발광된 광이 뒷창문(1)을 투과하여 수광부(2b)에 수광된다.Next, when there is no frost on the rear window 1, the light emitted from the photodiode PD is transmitted to the rear window 1 and received by the light receiving unit 2b.

수광부(2b)의 포토트랜지스터(PT)는 수광되는 광에 의해 턴-온되고, 이로인해 연산증폭기(OP1)의 비반전단자(+)에 전압(Vcc)이 걸리게되어 연산증폭기(OP1)의 출력전압(Vo)은 비반전단자(+)와 반전단자(-)의 전압차가 증폭되어 열선 제어부(3)에 입력된다.The phototransistor PT of the light receiving unit 2b is turned on by the received light, thereby applying a voltage Vcc to the non-inverting terminal + of the operational amplifier OP1, thereby outputting the operational amplifier OP1. The voltage Vo is amplified by the voltage difference between the non-inverting terminal (+) and the inverting terminal (-) and input to the heating wire controller 3.

열선 제어부(3)는 입력되는 고전위(5V)에 의해 트랜지스터(TR1)가 구동되고, 트랜지스터(TR1)의 구동에 의해 릴레이(RY)에는 구동전류가 흘러 릴레이(RY)도 구동이 된다.In the hot wire control unit 3, the transistor TR1 is driven by the input high potential 5V, and the drive current flows through the relay RY by the driving of the transistor TR1 so that the relay RY is also driven.

릴레이(RY)가 구동되면 열선 구동부(4)의 제 2 입력포트(I2)에는 전압(Vcc)이 입력되므로 열선 구동부(4)는 뒷 창문(1)에 서리가 발생되지 않은 것으로 인지하고 동작을 하지않게 된다.When the relay RY is driven, since the voltage Vcc is input to the second input port I2 of the heating wire driving unit 4, the heating wire driving unit 4 recognizes that no frost has occurred in the rear window 1 and operates. Will not.

즉, 열선 구동부(4)는 뒷 창문(1)에 서리가 발생된 경우에만 자동으로 동작하여 서리를 제거하게 되는 것이다.That is, the hot wire drive unit 4 automatically operates only when frost is generated in the rear window 1 to remove frost.

이상에서와 같이 본 발명은 뒷 창문에 발생되는 서리를 감지하고 서리가 발생된 경우 자동으로 열선을 구동시켜 서리를 제거하므로 사용자에 의해 시각적인 확인과 열선 구동을 위한 조작 스위치의 조작에 따른 불편함을 해소 시킬 수 있는 효과가 있다.As described above, the present invention detects frost generated in the rear window and automatically removes frost by driving a heating wire when frost is generated, thereby making it inconvenient according to a user's visual confirmation and operation of an operation switch for driving a heating wire. There is an effect that can be eliminated.
