Description
본 발명은 자동차의 환기장치에 관한 것이며, 상세하게는 자동차의 실내공기 강제 환기장치에 관한 것이다.The present invention relates to a ventilator of a vehicle, and more particularly to a forced air ventilation of the indoor vehicle.
주지하는 바와 같이 자동차의 환기장치는 도 2에 도시한 바와 같이 카울 탑 패널에 실외공기 유입구(1)를 형성하고, 상기 실외공기 유입구(1)로 부터 유입되는 실외공기는 공기 조화장치인 내·외기모드 절환 도어수단, 블로워, 증발기 코어 및 히터 코어를 경유하여 크래쉬 패드에 형성한 에어 벤트(4)를 통하여 실내에 유입되고, 실내공기는 리어 패키지 트레이 패널의 후방에 형성되는 통로(5)를 경유하여트렁크 룸에 모인 후 쿼터 패널(사이드 패널)에 형성한 실내공기 배출그릴(6)을 통하는 경로를 거쳐 외부로 배출되도록 되어 있다(도 2의 화살표 참조).As is well known, the automobile ventilation system forms an outdoor air inlet 1 on the cowl top panel as shown in FIG. 2, and the outdoor air introduced from the outdoor air inlet 1 is an air conditioner. The air is introduced into the room through the air vent 4 formed in the crash pad via the air mode switching door means, the blower, the evaporator core and the heater core, and the indoor air is provided with a passage 5 formed at the rear of the rear package tray panel. After the gas is collected in the trunk room, the gas is discharged to the outside via a path through the indoor air discharge grille 6 formed in the quarter panel (side panel) (see the arrow in FIG. 2).
상기한 환기 경로를 형성할 때 실외공기 유입구(1)는 주행시의 풍압이 정압(正壓)의 위치에 형성하고, 실내공기 배출그릴(6)은 부압(負壓)의 위치에 형성하여 운전석 근처에 설치한 외기모드 조작노브를 “온”으로 조작하면 실외공기 유입구(1)로 유입되는 정압의 외기에 의하여 실내공기를 실내공기 배출그릴(6)로 밀어냄으로써 실내를 환기하도록 되어 있다.When the ventilation path is formed, the outdoor air inlet 1 is formed at the position where the wind pressure at the time of driving is positive, and the indoor air discharge grill 6 is formed at the position of the negative pressure, near the driver's seat. When operating the air mode operation knob installed in the “on”, the indoor air is ventilated by pushing the indoor air to the indoor air discharge grill 6 by the positive pressure outdoor air flowing into the outdoor air inlet 1.
그러나 자동차의 환기 경로를 설계할 때 특히 실외공기 유입구(1)는 정압이 최대로 걸리는 위치에 선정하는 것이 바람직하나, 실외공기 유입구(1)는 그 형상의 결정시에 차량의 디자인과 관련되는 것임으로 실외공기 유입이 원활히 되는 위치에 선정하는데 한계가 있어 실외공기 유입이 양호하지 못하고, 또한 실외공기 유입을 양호하게 하기 위하여 실외공기 유입구(1)의 단면적을 크게 형성하면 우천시 또는 수밀 시험시에 물방울이 실내로 유입되는 다른 문제점이 발생하는 것이다.However, when designing the ventilation path of the vehicle, it is preferable to select the outdoor air inlet 1 at the position where the static pressure is maximized, but the outdoor air inlet 1 is related to the design of the vehicle at the time of determining the shape. The outdoor air inflow is not good because there is a limit in selecting the location where the outdoor air inflows smoothly. Also, if the cross-sectional area of the outdoor air inlet 1 is formed large in order to improve the outdoor air inflow, water droplets may be generated during rainy or watertight tests. Another problem is introduced into the room.
또한 실외공기 유입구(1)와 에어 벤트(4) 사이에는 저항요소인 증발기 코어, 히터 코어 및 덕트 등이 위치함으로 이들의 저항요소에 의하여 실외공기 유입이 원활히 되지 못함으로서 환기성능이 더욱더 나빠지게 되며, 환기성능이 나빠지게 되면 윈드 실드 글래스 등에 습기 등이 생성되어 시야 확보가 충분하지 못하며, 이산화탄소의 농도가 증가하고 산소부족으로 되어 졸음운전의 원인이 되는 것이다.In addition, since the evaporator core, the heater core, and the duct, which are the resistance elements, are located between the outdoor air inlet 1 and the air vent 4, the ventilation performance becomes worse as the outdoor air is not smoothly inflowed by these resistance elements. If the ventilation performance is deteriorated, moisture is generated in the windshield glass, and thus the visibility is not sufficient, and the concentration of carbon dioxide increases and the lack of oxygen causes drowsiness operation.
본 발명은 상기한 문제점을 시정하여, 실내공기를 강제적으로 배출하여 환기성능을 양호하게 유지토록 한 자동차의 환기장치를 제공하는 것을 목적으로 한다.An object of the present invention is to provide a ventilation device for a vehicle to correct the above problems, forcibly discharging indoor air to maintain a good ventilation performance.
상기한 목적을 달성하기 위하여, 본 발명은 카울 패널에 형성한 실외공기 유입구와, 상기 실외공기 유입구에 연결되는 덕트에 설치한 내·외기모드 절환 도어수단과, 양단을 실내와 배기 파이프에 형성한 벤튜리에 개구하고 중간에 밸브기구를 설치한 배출관과, 실내에 설치한 이산화탄소 센서와, 상기 이산화탄소 센서의 검출신호에 의하여 상기 밸브기구를 개폐함과 동시에 상기 내·외기모드 절환 도어수단이 내기모드 위치에 있을 때 외기모드 위치로 절환하는 제어수단으로 구성한 것이다.In order to achieve the above object, the present invention provides an outdoor air inlet formed in the cowl panel, an internal / external air mode switching door means installed in a duct connected to the outdoor air inlet, and both ends formed in the indoor and exhaust pipes. A discharge pipe in which the valve mechanism is opened in the middle of the venturi, the carbon dioxide sensor installed in the room, and the valve mechanism is opened and closed by the detection signal of the carbon dioxide sensor and the internal / external mode switching door means It is composed of a control means for switching to the external mode position when in the.

The indoor air is discharged to the discharge pipe 10 by the negative pressure generated in the exhaust pipe 11. The actuator 23 is “off” when the outside mode operation knob installed near the driver's seat is operated “on” and “on” when the betting mode operation knob is operated “on”, and the indoor air as described above. Is discharged to the outside through the discharge pipe 10, when the door 21 of the internal / external mode switching door means 2 is in the betting mode position (imaginary line in Fig. 1), the control means 20 is the actuator ( A signal is output to the door 23 to switch the door 21 to the outside air mode side (solid line in FIG. 1) so that outdoor air enters the room through the outside air inlet 1, and the door 21 is located in the outside air mode. When it is at the door 23 is not to output a signal to the actuator 23 so that the outdoor air flows into the room in the outdoor mode position state.
그리고 상기 제어수단(20)의 신호 출력측에 릴레이(21)를 연결하여 일정시간 동안 액츄에이터(133)(23)를 구동함으로써 외기의 유입량을 증대시켜서 환기를 더욱더 양호하게 한 것이다.In addition, the relay 21 is connected to the signal output side of the control means 20 to drive the actuators 133 and 23 for a predetermined time, thereby increasing the inflow of outside air, thereby making the ventilation even better.

이상과 같은 본 발명은 엔진의 구동시에 배출관(10)이 폐쇄되고 내·외기 모드 절환 도어수단(2)의 도어(21)가 외기모드 위치에 있을 때 제어수단(20)이 실내에 설치한 이산화탄소 센서(30)의 검출신호를 입력받아 맵에서 기설정된 설정치와 비교하여 이산화탄소량이 설정치 이상일 때 액츄에이터(133)에 신호를 출력함으로써 밸브(131)가 개방되고 밸브(131)가 개방되면 엔진에서 배출되는 배기가스가 벤튜리(12)를 통과할 때 발생되는 부압에 의하여 실내공기를 흡인하여 배기가스와 함께 강제로 배출되고, 상기와 같이 실내공기가 강제로 배출됨에 따라 실외공기 유입구(1)를 통하여 외기가 실내에 유입되어 실내가 강제 환기되는 것이다.According to the present invention as described above, when the exhaust pipe 10 is closed when the engine is driven and the door 21 of the internal / external air mode switching door means 2 is in the external air mode position, the control means 20 is installed in the room. When the detection signal of the sensor 30 is input, the valve 131 is opened by outputting a signal to the actuator 133 when the amount of carbon dioxide is greater than or equal to the preset value in the map, and then discharged from the engine when the valve 131 is opened. When the exhaust gas passes through the venturi 12, the indoor air is sucked by the negative pressure generated by the negative pressure and forcedly discharged together with the exhaust gas. As the indoor air is forcibly discharged as described above, the outdoor air is introduced through the inlet port 1. The outside air flows into the room and the room is forcedly ventilated.
한편 내·외기모드 절환 도어수단(2)의 도어(21)가 내기모드에 위치되었을 경우에는 상기 내·외기모드 절환 도어수단(2)의 도어(21)가 외기모드에 위치되었을 경우와 같이 밸브(131)가 개방됨과 동시에 제어수단(20)에서 내·외기모드 절환 도어수단(2)의 액츄에이터(23)에 신호를 출력함으로써 내기모드 위치에 있던 도어(21)가 외기모드 위치측으로 절환되어 실외공기 유입구(1)를 통하여 외기가 실내에 유입되어 강제 환기되는 것이다.On the other hand, when the door 21 of the internal / external air mode switching door means 2 is located in the internal air mode, the valve 21 is similar to the case where the door 21 of the internal / external air mode switching door means 2 is located in the external air mode. 131 is opened and the control unit 20 outputs a signal to the actuator 23 of the internal / external mode switching door means 2 so that the door 21 in the internal mode is switched to the external mode position side, Outside air is forced into the room through the air inlet (1).
이상과 같이 본 발명은 실내의 플로워와 배기 파이프의 벤튜리에 밸브기구를 설치한 배출관을 연결하고 이산화탄소 센서의 검출신호를 입력받은 제어수단이 상기 밸브기구를 개방하여 실내환기를 강제적으로 실시함으로써 실내환기를 양호하게 하여 쾌적한 탑승을 할 수 있게 하고, 실내환기가 양호함에 따라 윈드 실드 글래스 등의 습기제거가 양호하여 시야확보가 충분하고 실내가 쾌적함으로 졸음운전도 방지됨으로 안전운전을 할 수 있는 것이다.As described above, the present invention connects a discharge pipe having a valve mechanism to a floor of an indoor floor and a venturi of an exhaust pipe, and a control means receiving a detection signal of a carbon dioxide sensor opens the valve mechanism to force indoor ventilation. It is possible to make a comfortable ride by a good, and the indoor ventilation is good to remove moisture, such as windshield glass is good enough to secure the field of view and the interior is comfortable to prevent drowsy driving can be safe driving.
