이하 본 발명의 바람직한 실시예를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.
제1도에 도시된 바와 같이, 자동차의 도아(2)에 위치하는 윈도우에 자동차의 실내를 밀폐하면서 플레이트(4)가 고정되게 설치된다.As shown in FIG. 1, the plate 4 is fixedly installed while sealing the interior of the vehicle in a window located in the door 2 of the automobile.
또한, 상기 플레이트(4)에 실내를 향하여 위치하는 에어닥트(6)를 연결하여 설치하되, 이 에어닥트(6)의 일단에 공기를 가변 시키면서 송풍할 수 있도록 된 에어펌프(8)가 풍량 조절스위치(10)를 구비하면서 연결되어 설치되고, 동시에 이 에어펌프(8)는 하우징(12)내에 고정 설치된다.In addition, the air pump (8) is installed to connect the air duct (6) located in the room (4) toward the room, the air pump (8) to be blown while varying air at one end of the air duct (6) The air pump 8 is fixedly installed in the housing 12 while being connected and installed with the switch 10.
그리고, 상기 하우징(12)내에 자동차의 실내 압력을 표시하는 압력 인디케이터(14)가 고정 설치되고, 이 압력 인디케이터(14)에 자동차의 실내 압력을 측정할 수 있도록 된 압력센서(16)가 연결되어 설치된다.In addition, a pressure indicator 14 for displaying the indoor pressure of the vehicle is fixedly installed in the housing 12, and a pressure sensor 16 is connected to the pressure indicator 14 to measure the indoor pressure of the vehicle. Is installed.
동시에 이 압력센서(16)에 상시 플레이트(4)를 관통하면서 실내를 향하여 압력라인(18)이 연결되어 설치된다.At the same time, a pressure line 18 is connected to the pressure sensor 16 toward the room while passing through the plate 4 at all times.
상기와 같이 구성되는 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
먼저 에어펌프(8)를 작동시키게 되면, 에어펌프(8)에 의하여 공기가 에어닥트(6)를 통하여 자동차의 실내로 송풍된다.When the air pump 8 is first operated, air is blown by the air pump 8 through the air duct 6 into the interior of the vehicle.
상기와 같이 에어닥트(6)를 통하여 공기가 송풍되면, 자동차의 실내에 일정한 압력이 발생하게 된다.When air is blown through the air duct 6 as described above, a constant pressure is generated in the interior of the vehicle.
이때, 에어펌프(8)로부터 송풍되는 공기는 실내에서 발생하는 압력에 의하여 저항을 받게 되는데, 이로 인하여 송풍되는 공기는 역으로 에어펌프(8)를 향하게 된다.At this time, the air blown from the air pump 8 is subjected to resistance by the pressure generated in the room, thereby the air blown is directed toward the air pump (8).
상기와 같이 송풍되는 공기가 자동차의 실내에서 일정한 압력을 발생시키게 되면, 압력라인(18)을 따라 공기가 압력센서(16)에 도달하게 되는데, 이로 인하여 압력이 체크되고, 동시에 그 압력의 정도가 압력 인디케이터(14)에 표시된다.When the air blown as described above generates a constant pressure in the interior of the vehicle, the air reaches the pressure sensor 16 along the pressure line 18, whereby the pressure is checked, and at the same time the degree of pressure Displayed on the pressure indicator 14.

따라서, 자동차의 실내에 발생된 압력에 의하여 저항받는 공기가 저항을 극복하고 자동차의 실내에 공급된다.Therefore, the air resisted by the pressure generated in the interior of the vehicle overcomes the resistance and is supplied to the interior of the vehicle.
이때, 압력라인(18)을 따라 증가된 압력이 전달되면서 압력센서(16)에 체크되고, 동시에 그 압력의 정도가 압력 인디케이터(14)에 나타난다.At this time, the increased pressure is transmitted along the pressure line 18 and checked by the pressure sensor 16, and at the same time the degree of the pressure is displayed on the pressure indicator 14.
이상에서 설명한 바와 같이 본 발명은, 토출구를 통하여 유출되는 냉기나 온기의 풍량을 실제값에 근접되게 측정할 수 있도록 함으로서, 주행중 속도변화에 따라 발생하는 차내 기압을 극복하여 원활히 토출이 이루어지도록 하는 효과가 있다.As described above, the present invention allows the amount of cold air or warm air flowed out through the discharge port to be measured to be close to the actual value, thereby overcoming the in-vehicle air pressure generated by the speed change while driving, so that the discharge is performed smoothly. There is.
