Abstract

PURPOSE: An air conditioner for a vehicle is provided to reduce a mounting space and to improve air-conditioning efficiency through a short distance between ducts by mounting a heater, an evaporator and a blower motor unit between a dash panel and a crash panel. CONSTITUTION: Air flows to an intake duct(18) between a cowl chamber(24) and a dash panel(26) through a cowl top panel. The air flows through a blower motor(14) immediately after an internal/external set door(28). Then the air flows via an evaporator(16). If a warm/cool door(22) is opened, the air flows into inside through a vent duct(30) and a vent grille of a crash panel via a hole of a film door(20) on a case body(10). The film door hole is met with the opened warm/cool door when the cold air flows therethrough. If the warm/cool door is closed, the air flows to a heater core(12) through the evaporator. The film door is rotated to meet the hole with the upper face of the heater core. A foot mode door is opened when a user selects a foot mode to blow indoor air toward a foot. Thereby, the air is blown into inside via a foot mode grille from the heater core or the evaporator.

따라서, 상기와 같은 구성의 장치들이 응집되어 설치된 케이스바디(10)를케이스 바디(10)를 차량의 대쉬패널(26)과 크래쉬패드 사이의 공간에 설치하게 되면, 상기 필름도어(20)의 상면에는 크래쉬패드의 벤트그릴과 연결되는 벤트덕트(30)가 위치되어진다.Therefore, when the case body 10 is installed in a condensed manner, the case body 10 installed in the space between the dash panel 26 and the crash pad of the vehicle, the upper surface of the film door 20 There is a vent duct 30 is connected to the vent grill of the crash pad.

특히, 상기 블로워모터(14) 하단의 내외기 설정도어(28)에는 카울챔버(24)와 대쉬패널(26)사이에 형성시킨 흡입덕트(18)가 연결되어진다.In particular, the suction duct 18 formed between the cowl chamber 24 and the dash panel 26 is connected to the internal and external air setting doors 28 at the bottom of the blower motor 14.

여기서 상기와 같은 구성을 갖는 본 발명의 자동차용 공조장치의 작동상태를 설명하면 다음과 같다.Here will be described the operating state of the vehicle air conditioner of the present invention having the configuration as described above.

카울 탑패널로 유입된 공기는 카울챔버(24)와 대쉬패널(26)사이에 형성시킨 흡입덕트(18)로 유도되어, 상기 내외기 설정도어(28)를 통과하는 즉시, 상기 블로워모터(14)를 통과하게 된다.The air flowing into the cowl top panel is led to the suction duct 18 formed between the cowl chamber 24 and the dash panel 26, and immediately after passing through the internal / external air setting door 28, the blower motor 14 Will pass).

상기 블로워모터(14)를 통과한 공기는 증발기(16)를 경유하는 동시에 상기 웜/쿨도어(22)가 열려져 있는 경우에는 케이스바디(10)의 상부에 장착된 필름도어(20)의 홀을 빠져나가 벤트덕트(30)과 크래쉬패드의 벤트그릴를 거쳐 실내로 유입되어진다. 이때의 공기는 냉공기이다.The air passing through the blower motor 14 passes through the evaporator 16 and, when the worm / cool door 22 is opened, opens the hole of the film door 20 mounted on the case body 10. It exits and is introduced into the room through the vent grill of the vent duct 30 and the crash pad. Air at this time is cold air.

특히, 상기 필름도어(20)는 상기 냉공기가 통과할때에는 필름도어(20)의 회전으로 필름도어의 홀과 상기 열려진 웜/쿨도어(22)와 일치된 상태가 되도록 한다.In particular, when the cold air passes through the film door 20, the film door 20 rotates with the film door 20 so that the film door 20 is aligned with the hole of the film door and the opened worm / cool door 22.

한편, 상기 웜/쿨도어(22)가 닫혀져 있을때에는 상기 증발기(16)를 통과한 공기는 히터코어(12)로 흐르게 되는 동시에 상기 필름도어(20)는 회전하여 필름도어(20)의 홀이 히터코어(12)의 상면과 일치되는 위치로 변위되어진다.On the other hand, when the worm / cool door 22 is closed, the air passing through the evaporator 16 flows to the heater core 12 and the film door 20 rotates so that the hole of the film door 20 is rotated. The heater core 12 is displaced to a position coinciding with the upper surface.

또한, 운전자는 실내공기의 유입방향을 풋(foot)쪽으로 유입되도록풋모드(foot mode)로 설정하게 되면, 풋 모드 도어가 열리게 되는 동시에 히터코어(12) 또는 증발기(16)를 통과한 공기가 풋 모드 그릴을 경유하여 실내로 유입되어진다.In addition, when the driver sets the foot mode so that the inflow direction of the indoor air flows into the foot, the foot mode door is opened and air passing through the heater core 12 or the evaporator 16 It enters the room via the foot mode grille.

이상에서 본 바와 같이, 본 발명에 따른 자동차용 공조장치에 의하면, 하나의 케이스 바디내에 히터, 증발기, 블로워모터 유니트를 미리 설치하여 단순화시킨 유니트로 구성하여, 차량의 엔진룸과의 차폐판인 대쉬패널과 크래쉬패드 사이 공간에 장착시킬 수 있도록 함으로써, 장착작업이 용이하고 설치공간이 작아도 설치가 가능하여 공간활용도를 높일 수 있으며, 덕트간의 길이가 짧아져 공조효율을 향상시킬 수 있는 효과가 있다.As described above, according to the automotive air conditioner according to the present invention, a heater, an evaporator, and a blower motor unit are pre-installed in one case body, and configured as a simplified unit, and a dash which is a shield plate with the engine room of the vehicle. By being able to be mounted in the space between the panel and the crash pad, the mounting work is easy and installation is possible even if the installation space is small, so that the space utilization can be increased, and the length between the ducts is shortened, thereby improving the air conditioning efficiency.
