본 발명은 차량용 실내온도 조절장치에 관한 것으로서, 더욱 상세하게는 실내와 실외의 온도차이로 인한 제베크 효과로 발생되는 열기전력을 이용하여 실내의 온도를 신속하게 조절할 수 있는 차량용 실내온도 조절장치에 관한 것이다.The present invention relates to a vehicle indoor temperature control device, and more particularly to a vehicle indoor temperature control device that can quickly control the indoor temperature by using the thermal power generated by the Seebeck effect due to the temperature difference between the indoor and outdoor. It is about.

일반적으로 자동차에는 편의시설로서 공조 시스템이 구비되어있고, 그 공조 시스템은 겨울철에는 히터를 동작시켜 차내의 온도를 높이고, 여름철에는 에어콘을 동작시켜 차내의 온도를 낮춤으로써 운전자가 쾌적한 환경에서 운전을 할 수 있도록 하고 있다.In general, a vehicle is equipped with an air conditioning system as a convenience facility, and the air conditioning system operates a heater in winter to increase the temperature in the car, and in summer, operates an air conditioner to lower the temperature in the car so that the driver can operate in a comfortable environment. To make it possible.

도 1은 종래의 실내온도 조절장치를 나타낸 개략도로서, 여기에서 참조되는바와 같이 외부의 공기를 차 실내로 유입시키거나 차 실내의 공기를 순화시키는 공조장치(1)는 크레쉬 패드(2)의 내부에 설치되어 있고, 상기 크레쉬 패드(2)의 전면에는 공기의 토출 방향 및 토출 공기의 온도를 조절하는 조작부(3)가 설치되어 있다.1 is a schematic view showing a conventional room temperature control device, wherein the air conditioner (1) which introduces outside air into the car interior or purifies the air in the car interior, as referred to herein, is an interior of the crash pad (2). The operation part 3 which controls the discharge direction of air and the temperature of discharged air is provided in the front surface of the said crash pad 2.

따라서, 운전자가 조작부(3)를 조작하면 그 조작부(3)에 입력되는 제어명령에 따라서, 공기의 순환 경로 및 온도가 조절되는 것이며, 이와 같이 조절된 공기는 차 실내를 난방 또는 냉방시키면서 차 실내의 공기를 운전자가 요구하는 온도로 유지하게 되므로 차 실내를 쾌적한 환경으로 조성하는 것이다.Therefore, when the driver operates the operation unit 3, the circulation path and the temperature of the air are adjusted according to the control command inputted to the operation unit 3, and the adjusted air is used to heat or cool the vehicle interior while heating or cooling the vehicle interior. The air is kept at the temperature required by the driver, thus creating a comfortable environment inside the car.

그러나 이러한 종래의 장치는 운전자가 직접 조작을 할 경우에만 공조시스템이 작동하게 됨은 물론, 작동 후에도 차 실내의 온도가 운전자가 요구하는 온도를 유지하기 위해서는 일정시간 이 경과하여야 하는 문제점이 있었다. However, such a conventional apparatus has a problem that the air conditioning system operates only when the driver directly operates, and, after operation, a certain time must elapse to maintain the temperature required by the driver even after the operation.                         

특히, 실내의 온도가 높은 여름철이나 온도가 낮은 겨울철에는 운전조건이 저하되므로 실내의 온도가 조절될 때까지 소정시간 경과 후 주행하여야 하는 등의 문제점이 있었다. In particular, since the operating conditions are deteriorated in the summer or in the winter when the temperature is high in the room temperature, there is a problem such as driving after a predetermined time until the indoor temperature is adjusted.

여기에서 참조되는 바와 같이 본 발명은 차량의 실내와 실외 온도 차이를 감지하도록 글라스(60)에 온도감지부(10)가 설치되어 있되, 그 온도감지부(10)는 열기전력이 발생되는 제베크소자(열전자소자)를 사용하는 것으로서, 글라스(60)의 내외부에 각각 제1금속(11)이 설치되어 있고, 상기 제1금속(11)의 사이는 제2금속(12)이 설치되어 있으며, 상기 제1금속(11) 및 제2금속(12)과 글라스(60)의 접촉면에는 차단재(13)가 설치되어 있다.As referred to herein, the temperature sensing unit 10 is installed on the glass 60 so as to sense a difference between an indoor and an outdoor temperature of the vehicle, and the temperature sensing unit 10 is a Seebeck where thermal power is generated. An element (thermoelectronic element) is used, and a first metal 11 is provided inside and outside the glass 60, and a second metal 12 is provided between the first metal 11, The blocking material 13 is provided on the contact surface between the first metal 11, the second metal 12, and the glass 60.

한편, 상기 온도감지부(10)는 열기전력을 입력받아 기준값과 비교하여 실내와 실외의 온도가 소정온도(약 10℃)이상 차이가 발생되면 제어신호를 발생시키는 ECU(20)에 연결되어 있고, 상기 ECU(20)에는 그 ECU(20)에서 발생되는 제어신호에 의해서 동작되어 실내의 공기를 조절하는 공조시스템(30)이 연결되어 있으며, 그 공조시스템(30)에는 공기의 토출 방향을 조절하는 엑츄에이터(40)가 설치되어 있다.On the other hand, the temperature sensing unit 10 is connected to the ECU 20 for generating a control signal when the difference between the indoor temperature and the outdoor temperature is a predetermined temperature (about 10 ℃) or more compared to the reference value by receiving the thermal power In addition, the ECU 20 is connected to an air conditioning system 30 that operates by a control signal generated by the ECU 20 to regulate indoor air, and the air conditioning system 30 adjusts a discharge direction of air. An actuator 40 is provided.

그리고, 상기 각 부분에는 전원을 공급하기 위한 배터리(50)가 연결되어 있다.And, each of the parts is connected to a battery 50 for supplying power.

이와 같이 구성된 본 발명을 상세히 설명하면 다음과 같다.Referring to the present invention configured as described in detail as follows.

먼저, 차량의 실내와 실외의 온도차이가 발생되면 온도감지부(10)에는 제베 크효과(Seebeck Effect)에 의해서 열기전력이 발생되게 된다.First, when the temperature difference between the indoor and outdoor of the vehicle is generated, the thermoelectric power is generated in the temperature sensing unit 10 by the Seebeck effect.

상기 제베크 효과를 상세히 설명하면 도 4에 나타낸 바와 같이 한 쌍의 제1금속(11)과 그 제1금속을 연결하는 제2금속(12)의 접촉면에 온도차이가 발생되면 열기전력이 발생하여 전류가 흐르는 현상으로서, 본 발명의 온도감지부(10)에 설치된 제1금속(11)과 제2금속(12)의 접촉면에는 열기전력이 발생되게 된다.Referring to FIG. 4, the thermal effect is generated when a temperature difference occurs between the contact surfaces of the pair of first metals 11 and the second metals 12 connecting the first metals. As a phenomenon in which current flows, thermoelectric power is generated on a contact surface between the first metal 11 and the second metal 12 provided in the temperature sensing unit 10 of the present invention.

이러한 열기전력은 온도차가 클수록 발생하는 전압도 크게된다.The greater the temperature difference, the greater the voltage generated.

이때 발생된 전압은 ECU(20)로 송신되고 그 ECU(20)에서는 메모리에 저장된 기준값과 비교하여 실외 온도와 실내온도의 차이를 연산하게 되는 것이고, 상기 온도차이가 소정온도(약 10℃)이상 발생되면 ECU(20)에서는 엑츄에이터(40)를 작동시켜 공조시스템(30)을 자동으로 가동, 조절 및 정지시키면서 차 실내의 온도를 최적한 상태로 유지하게 된다.The generated voltage is transmitted to the ECU 20 and the ECU 20 calculates a difference between the outdoor temperature and the indoor temperature by comparing with the reference value stored in the memory, and the temperature difference is greater than a predetermined temperature (about 10 ° C.). When generated, the ECU 20 operates the actuator 40 to automatically operate, adjust, and stop the air conditioning system 30 to maintain the optimum temperature of the vehicle interior.

즉, 여름철에는 실내 온도가 실외 온도보다 10℃이상 높아질 경우이고, 겨울철에는 실내 온도가 실외 온도보다 10℃이상 낮아진 경우이다. That is, in summer, the indoor temperature is higher than the outdoor temperature by more than 10 ℃, and in winter, the indoor temperature is lower than the outdoor temperature by more than 10 ℃.

따라서, 실내온도가 실외온도보다 높아지는 여름철에는 에어컨 및 환기기능이 작동되는 것이고, 실내온도가 실외온도보다 낮아지는 겨울철에는 히터 및 환기기능이 작동되는 것이다.Therefore, the air conditioner and the ventilation function is operated in the summer when the indoor temperature is higher than the outdoor temperature, and the heater and the ventilation function is operated in the winter when the indoor temperature is lower than the outdoor temperature.

상술한 바와 같이 본 발명은 차량의 실내 온도와 실외 온도의 차이를 검출하고 그 온도차이가 소정온도 이상 발생되면 냉난방 장치 및 환기장치를 자동으로 작동시켜 차 실내의 온도를 일정하게 유지하게 되므로 온도 차이가 심한 여름철 및 겨울철에도 운전자가 차량에 탑승과 동시에 주행할 수 있는 쾌적한 환경을 유지할 수 있게되는 특유의 효과가 있다. As described above, the present invention detects the difference between the indoor temperature and the outdoor temperature of the vehicle, and if the temperature difference is greater than a predetermined temperature, the air conditioner and the ventilator are automatically operated to maintain a constant temperature inside the vehicle. Even in the severe summer and winter, there is a unique effect that allows the driver to maintain a comfortable environment in which the driver can drive simultaneously with the vehicle.

이와 같이 본 발명은 차량의 실외와 실내의 온도차이를 감지하는 온도감지부의 제베크 효과로 인한 열기전력을 이용하여 차량의 실내 온도를 신속하게 조절하게 되므로 쾌적한 실내 공기를 유지할 수 있게되는 특유의 효과가 있다.As described above, the present invention uses a thermoelectric power due to the Seebeck effect of the temperature sensing unit for detecting a temperature difference between the outdoor and the indoor of the vehicle, so that the indoor temperature of the vehicle can be quickly adjusted. There is.
