従って外気導入口１４からは外気が積極的に安定して吸
引され、その外気導入量は外気導入口１４の大きさが小
さい割には多くなり、これにより車室内の相対湿度が大
きく低下することを防止することができて快適な暖房を
行うことができる。Therefore, the outside air is actively and stably sucked in from the outside air inlet 14, and the amount of outside air introduced is large considering the small size of the outside air inlet 14, and as a result, the relative humidity inside the vehicle cabin is significantly reduced. It is possible to prevent this and provide comfortable heating.
なお外部の気温が特に低いときに内気暖房のみを行いた
い場合には、内外気切換ダンパー１８を外気導入口１４
側に揺動させて外気導入口１４を閉鎖すると共に内外気
兼用通路４ａの内気導入口２０を開くことによって行え
る。Note that if you want to perform only indoor air heating when the outside temperature is particularly low, the inside/outside air switching damper 18 can be connected to the outside air inlet 14.
This can be done by swinging it to the side to close the outside air inlet 14 and open the inside air inlet 20 of the indoor/outside air passageway 4a.
この場合、内外気兼用通路４ａと内気専用通路４ｂの両
方を通して内気を大量に吸引することができて効率の良
い暖房を行うことができる。In this case, a large amount of inside air can be sucked through both the inside and outside air passageway 4a and the inside air exclusive passageway 4b, and efficient heating can be performed.
次に冷房運転する場合には、吹出口切換ダンパー１２を
第１図の実線にて示すように揺動させて車室用吹出口３
を開くと共に分岐口１０を閉鎖し、また内外気切換ダン
パー１８を第１，２図の実線にて示すように揺動させて
内外気兼用通路４ａの内気導入口２０を開くと共に外気
導入口１４を閉鎖し、この状態で冷房運転を開始する。Next, when performing cooling operation, the air outlet switching damper 12 is swung as shown by the solid line in FIG.
The branch port 10 is opened and the branch port 10 is closed, and the inside/outside air switching damper 18 is swung as shown by the solid line in FIGS. is closed and cooling operation is started in this state.
従って、送風機９は内気吸込口２から内気を吸い込んで
エバポレータ８内に吸い込み、このエバポレータ８によ
って冷却された空気を内外気兼用通路４ａと内気専用通
路４ｂの両方から効率良く吸い込んで車室用吹出口３か
ら吹出させ、車室内を冷房する。Therefore, the blower 9 sucks inside air from the inside air suction port 2 and sucks it into the evaporator 8, and efficiently sucks the air cooled by the evaporator 8 from both the inside and outside air passage 4a and the inside air exclusive passage 4b to blow the air into the passenger compartment. The air is blown out from the outlet 3 to cool the interior of the vehicle.
この冷房運転を行う場合、外気導入口１４の大きさを比
較的小さく構成し、内外気切換ダンパー１８による外気
導入口１４の閉鎖を容易に確実に行えるようにしである
から、外気導入口１４からの外気の吸込みをほとんど無
くすことができて冷房効果を良くすることができる。When performing this cooling operation, the size of the outside air inlet 14 is configured to be relatively small so that the outside air inlet 14 can be easily and reliably closed by the inside/outside air switching damper 18. It is possible to almost eliminate the intake of outside air and improve the cooling effect.
また、車室内の空気が汚れて外気を一部導入しながら冷
房運転したい場合には内外気切換ダンパー１８を切換え
て外気導入口１４を開くと共に内外気兼用通路４ａの内
気導入口２０を閉鎖することによって行うことができる
。Further, when the air inside the vehicle is dirty and it is desired to perform cooling operation while introducing some outside air, the inside/outside air switching damper 18 is switched to open the outside air inlet 14 and close the inside air inlet 20 of the inside/outside air passageway 4a. This can be done by:
この場合、外気導入口１４と送風機間の送風通路４が仕
切プレート１７によって仕切られているので、エバポレ

。As described above, in the present invention, the outside air inlet is provided at the rear of the evaporator to introduce outside air without passing through the evaporator, and a partition plate is provided in the ventilation passage between the outside air inlet and the blower. The internal/external air switching damper is used to divide the passage into an internal/external air passageway and an internal air exclusive passageway, and the inlet of the internal/external air passageway and the external air intake port can be selectively opened and closed using an internal/external air switching damper. When introducing outside air from the mouth, the outside air can be introduced actively and efficiently using a blower with little air resistance, and the amount of outside air introduced from the outside air introduction port can be increased.
従って、外気導入口の大きさを相対的に小さくすること
ができ、これにより内外気切換ダンパーによる外気導入
口の開閉を比較的簡単な装置で確実に行える効果がある
。Therefore, the size of the outside air inlet can be made relatively small, which has the effect that the outside air inlet can be reliably opened and closed by the inside/outside air switching damper with a relatively simple device.
