Description

자동차 후방 윈도우의 열선장치Heating device of car rear window

본 발명은 자동차 후방 윈도우 상에 형성되는 성에 등을 제거시키기 위한 자동차용 열선장치에 관한 것으로, 보다 상세하게는 차량 주변의 온도 변화에 따라 자동적으로 작동되도록 설치된 자동차 후방 윈도우의 열선장치에 관한 것이다.The present invention relates to a heating apparatus for a vehicle for removing frost and the like formed on the rear window of the vehicle, and more particularly, to a heating apparatus for a rear window of a vehicle installed to be automatically operated according to a temperature change around the vehicle.

일반적으로, 자동차의 주행 시에 있어서, 차실 내부 온도와 외부 온도간의 차이에 의해 차량의 전방, 측방 및 후방 윈도우에 성에가 형성되어 시야를 흐리게 하는 경우가 있으며, 디프로스터는 이러한 자동차 윈도우의 흐려짐을 방지하고자하는 것으로, 차체의 인스트루먼트 패널에 장착된 디프로스터 덕트를 통해 난방 장치의 히터에 의해 가열된 공기를 흘려 보내므로써, 자동차 윈도우의 성에 형성을 방지하거나 이를 제거하는 기능을 한다.In general, during driving of a vehicle, frost is formed on the front, side, and rear windows of the vehicle due to the difference between the interior and exterior temperatures of the vehicle, and the vision is blurred. It is to prevent, by flowing the air heated by the heater of the heating device through the defroster duct mounted on the instrument panel of the vehicle body, thereby preventing or eliminating the formation of frost on the vehicle window.

이를 위해 디프로스터 덕트는 2개의 측면 배출구와, 2개의 상방 배출구 및 히터 장착부로 이루어져 있으며, 이러한 디프로스터 덕트는 히터 유니트 장착부에 의해 히터 유니트 상에 장착되고, 상기 각각의 측면 배출구와 상방 배출구는 인스트루먼트 패널상의 디프로스터 그릴(또는, 인스트루먼트 그릴)에 연결된다.To this end, the defroster duct consists of two side outlets, two upper outlets and a heater mount, which are mounted on the heater unit by means of a heater unit mount, each of the side outlets and the upper outlet being instrumented. It is connected to the defroster grille (or instrument grille) on the panel.

한편, 상술된 디프로스터는 주로 차량의 전방 윈도우와 도어 윈도우를 위하여 설치된 것이며, 자동차의 후방 윈도우의 경우에는 전방 윈도우와 같은 디프로스터를 설치하기가 곤란하므로, 후방 윈도우 내에 다수의 열선을 제공하여 열을 가하여 주므로써 윈도우에 형성되는 성에 등을 제거하도록 되어 있었다.Meanwhile, the above-described defroster is mainly installed for the front window and the door window of the vehicle, and in the case of the rear window of the vehicle, it is difficult to install a defroster such as the front window. By adding, the frost on the window was removed.

그런데, 이러한 종래의 열선장치는 운전자가 운전 중에 후방 윈도우를 통한 후방 시야가 성에 등으로 인하여 가려지게 되면, 운전석에 마련된 열선장치의 스위치를 작동시키므로써 작동하게 되는데, 대부분의 경우, 운전자가 운전에 지장이 있을 만큼 후방 시야가 흐려진 후에야 상기 열선장치를 작동시키게 되므로써 안전 운행에 지장을 초래하게 되는 것은 물론 성에를 제거시킨 후에는 열선장치의 작동을 다시 중지시켜야 하는 등의 불편함이 있었다.However, such a conventional heating device is operated by operating a switch of the heating device provided in the driver's seat when the driver's rear view through the rear window is blocked due to frost or the like while driving, in most cases, the driver may Since the heating device is operated only after the rear view is blurred enough to cause a problem, it causes inconvenience in safe driving, and it is inconvenient to stop the operation of the heating device again after removing the frost.

따라서, 본 발명은 이러한 종래의 불편함을 해결하기 위하여 제안된 것으로, 상기 열선장치의 작동구조를 개선하여, 운전자에 의한 수동 조작은 물론 차량 윈도우의 성에 형성의 원인이 되는 차량 주변의 온도에 따라 자동적으로 열선장치가 작동될 수 있도록 하는 것을 목적으로 한다.Accordingly, the present invention has been proposed to solve such a conventional inconvenience, and improves the operation structure of the heating apparatus, according to the temperature around the vehicle which causes not only manual operation by the driver but also the frost formation of the vehicle window. The purpose is to allow the heating system to operate automatically.

[실시예]EXAMPLE

이하, 첨부된 도면을 참조하여 본 발명의 양호한 실시예를 보다 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

여기서, 도 1은 본 발명에 따른 자동차 후방 윈도우의 열선장치 작동 회로도이다.1 is a circuit diagram of a heating device for a rear window of an automobile according to the present invention.

먼저, 본 발명에 의하면, 기존의 열선장치의 작동 회로 내에 별도로 전자석을 이용한 가변 스위치를 제공하며, 또한 이러한 가변 스위치를 차량의 주변 온도에 따라 작동되도록 하므로써 열선장치를 자동적으로 작동시킬 수 있게 된다.First, according to the present invention, a variable switch using an electromagnet is separately provided in an operation circuit of a conventional heating apparatus, and the heating apparatus can be automatically operated by operating the variable switch according to the ambient temperature of the vehicle.

이를 위하여, 도 1에 도시된 바와 같이, 본 발명에 따른 열선장치는 후방 윈도우 내에 설치되는 다수의 열선(1)과, 이러한 열선과 직렬로 연결된 전원(2)과, 자동차의 시동장치와 연결된 시동 스위치(3)와, 이러한 열선 회로를 수동적으로 개폐시키기 위한 수동 스위치(4)와, 상기 수동 스위치(4)와 병렬로 설치된 자동 스위치(5)와, 상기 자동 스위치(5)의 작동을 제어하기 위한 전자석(6)과, 상기 전자석(6)에 직렬로 설치되는 저항으로서의 핫코일(7)을 포함한다.To this end, as shown in Figure 1, the heating device according to the present invention is a plurality of heating wires (1) installed in the rear window, a power source (2) connected in series with such heating wires, starting with the starter of the vehicle To control the operation of the switch 3, a manual switch 4 for manually opening and closing such a hot wire circuit, an automatic switch 5 installed in parallel with the manual switch 4, and the automatic switch 5 And an electromagnet 6 for use, and a hot coil 7 as a resistor provided in series with the electromagnet 6.

상기 전자석(6)은 자동 스위치(5)와 나란하게 배열되어 전자석(6)에 전원이 연결되는 경우, 전자석(6)에 자력에 의하여 자동 스위치(5)를 개폐시키게 되고, 전원이 저하되면 전자석(6)의 자력 또한 저하되면서 자동 스위치(5)가 개방되도록 설치된다.The electromagnet 6 is arranged side by side with the automatic switch 5 when the power supply is connected to the electromagnet 6, the electromagnet 6 to open and close the automatic switch 5 by magnetic force, when the power is reduced the electromagnet As the magnetic force of (6) is also lowered, the automatic switch 5 is installed to open.

또한, 상기 핫코일(7)은 차량 주변의 온도에 따라 저항이 변화되어, 주변 온도가 높아지게 되면 저항이 증대되고, 주변 온도가 낮아지면 저항이 감소되게 된다.In addition, the resistance of the hot coil 7 is changed according to the temperature of the vehicle surroundings, the resistance is increased when the ambient temperature is increased, the resistance is reduced when the ambient temperature is lowered.

이러한 구성에 의하여, 차량의 시동이 걸리게 되면, 전자석(6)에 전원이 공급되어 자력이 형성되고, 이 때, 주변의 온도가 높은 상태라면, 상술된 바와 같이 전자석(6)에 연결된 핫코일(7)의 저항이 증대되므로써 전자석(6)에 공급되는 전류가 저하되어 전자석(6)의 자력이 저하되므로써 자동 스위치(5)가 개방된 상태를 유지하게 되어 열선장치가 작동되지 않게 되고, 만약 주변의 온도가 낮은 상태라면, 핫코일(7)의 저항이 저하되어 전자석(6)의 자력이 증대되므로써 자동 스위치(5)가 폐쇄되어 열선장치가 작동되게 된다.By this configuration, when the vehicle is started, power is supplied to the electromagnet 6 to form a magnetic force. At this time, if the ambient temperature is high, the hot coil 7 connected to the electromagnet 6 as described above. By increasing the resistance of), the electric current supplied to the electromagnet 6 is lowered, and the magnetic force of the electromagnet 6 is lowered, so that the automatic switch 5 is kept open and the heating apparatus is not operated. If the temperature is low, the resistance of the hot coil 7 is lowered and the magnetic force of the electromagnet 6 is increased, so that the automatic switch 5 is closed to operate the hot wire device.

또한, 상기 열선장치의 작동에 의해 후방 윈도우의 온도가 상승하게 되면, 핫코일의 온도가 증대되어 저항이 증가하므로써 자동 스위치(5)가 자동적으로 개방되게 된다.In addition, when the temperature of the rear window is increased by the operation of the hot wire device, the temperature of the hot coil is increased to increase the resistance so that the automatic switch 5 is automatically opened.

이상 상술된 바와 같이, 본 발명에 따른 자동차 후방 윈도우의 열선장치에 의하면, 차량 주변의 온도에 따라 열선장치의 작동을 자동적으로 제어할 수 있도록 하므로써 운전자의 편의성이 향상되는 효과가 있다.As described above, according to the heating apparatus of the rear window of the vehicle according to the present invention, it is possible to automatically control the operation of the heating apparatus according to the temperature of the vehicle surroundings, thereby improving the driver's convenience.
