。Air outside the vehicle (outside air) or inside the vehicle (inside air) (hereinafter referred to as cold air) is sent into the machine box from the side inlet 1a, singly or in a mixture, and a part of the cold air is sent to the heater 7a by the distribution damper 8a. The hot air is guided to the lower part of the mixing chamber 6a, and a part of the hot air is guided to the upper part of the mixing chamber 6a through the upper part of the damper 8a. However, due to restrictions on the size of the device, the mixing chamber 6a is generally small, so the mixture is not sufficiently mixed, and the upper part is relatively cold and the lower part is warm. Therefore, relatively cold air is guided to the discharge ports 2a and 3a toward the upper side of the vehicle interior, and relatively warm air is guided to the discharge ports 4a and 5a toward the lower side of the vehicle interior, and the temperature difference between the upper and lower warm air is comparatively large. The target is large, and it remains almost constant due to the shape etc. To change this temperature difference, damper 8
In addition to adjusting the distribution of cold air by a, upper discharge ports 2a and 3a
The distribution damper 9a) can be changed to some extent by using a damper 10a that controls the flow rate to the lower discharge ports 4a, 5a, or an additional damper, but at the same time the distribution of the flow rate to the lower discharge ports 4a to 5a
This caused a problem in that the ratio of the amount of air coming out of the tank also changed, and it was difficult to obtain an appropriate temperature difference. The present invention has been improved for the purpose of solving the above problems, and has the structure described in the claims. To specifically describe the embodiment shown in the drawings, a substantially rectangular cold air inlet 1 is vertically provided on the side surface of one end of an air conditioner box.

are provided, and the flow rate of cold air to the upper and lower passages 11, 12 and the lower half of the heater 7 on the road is adjusted on the cold air flower side of the heater 7. The lower passage 12 is extended in an approximately inverted L shape to the rear of approximately the lower half of the heater 7 by a guide plate 19, and the upper passage 1 above it is extended to the rear of approximately the lower half of the heater 7.
A space formed below the upper surface of the machine box as an extension of 1 is defined as a mixing chamber 6. Discharge ports 2 and 3 for sending warm air to the upper part of the vehicle interior are provided on the surface of the machine box at the rear inclined upper part of the mixing chamber 6. A passage 20 is formed below the passage 12 in a downward substantially inverted L shape along the guide plate 19, and communicates with the discharge ports 4 and 5 for sending hot air downward into the vehicle interior.
図示例のものは、導入口1に送風ダクト15を接続して

成されている。Alternatively, cold air cooled by a cooler inside the evaporator is introduced. The distribution dampers 13 and 14 are connected to shafts 13a and 1, respectively.
4a, and when it rotates to the outermost side (position H in Figure 1), it closes the upper and lower passages 11 and 12, and closes the upper and lower passages 11 and 12.
The heater 7 is configured to be fully closed when the heater 7 is rotated to the position (C position in the figure).

出口と乗員の上半身方向への吹出口に連通排風する。The two distribution dampers 13 and 14 may be manually or automatically linked in a fixed relationship, or may be controlled independently. The upper discharge ports 2 and 3 communicate with and exhaust air to a defroster air outlet of an instrument panel and an air outlet toward the upper body of the occupant, which are not shown in the figure, respectively.
18は軸18aを中心に回動するロータリ式ダンパで、
吐出口2,3への通路16,17を開閉して両吐出口2
,3から出る温風量の割合を制御する。18 is a rotary damper that rotates around a shaft 18a;
Opening and closing the passages 16 and 17 to the discharge ports 2 and 3
, 3 controls the rate of hot air volume.
下方の吐出口4,5は乗員の足元付近の車室内下方に開

御する。The lower discharge ports 4 and 5 open to exhaust air downward into the vehicle interior near the occupant's feet. A damper 21 rotates around a shaft 21a, which opens and closes the passage 20 to control the amount of hot air coming out of the discharge ports 4 and 5.
上記の構成であるから混合室6には、加熱器7を通つた
熱風とその上下の通路11,12を通つた冷風とが三層
伏態に入り込み、立上つた案内板19で通路12からの
冷風、加熱器7の下半部からの熱風が上向きに導かれ、
上部通路11からの冷風、加熱器7の上半部からの熱風
とよく混合して温風となるものであるが、上部通路11
の冷風量が下部通路12の冷風量よりも常に多く、かつ
その冷風の一部は機箱面に沿つて上部吐出口2,3に向
かう。With the above configuration, the hot air that has passed through the heater 7 and the cold air that has passed through the upper and lower passages 11 and 12 enter the mixing chamber 6 in a three-layer subterranean state, and are separated from the passage 12 by the raised guide plate 19. The cold air from the lower half of the heater 7 and the hot air from the lower half of the heater 7 are guided upward,
The cold air from the upper passage 11 mixes well with the hot air from the upper half of the heater 7 to become warm air.
The amount of cold air in the lower passage 12 is always larger than the amount of cold air in the lower passage 12, and a part of the cold air flows toward the upper discharge ports 2 and 3 along the machine box surface.
従つて車室内上部へ排出される温風が車室内下部への温
風よりも常に温度が低いことになる。従つて第3図aの
下グラフのように両ダンパ13,14を、第1図の加熱
器閉位置Cから、上下部閉位置Hに略同じ角度で回動さ
せると、同図上グラフのように上下部温風の温度差は余
り変らないで共に温度が上る。Therefore, the temperature of the warm air discharged to the upper part of the vehicle interior is always lower than that of the warm air discharged to the lower part of the vehicle interior. Therefore, when both dampers 13 and 14 are rotated at approximately the same angle from the heater closed position C in FIG. 1 to the upper and lower closed positions H as shown in the lower graph of FIG. As shown, the temperature difference between the upper and lower hot air does not change much, but the temperature of both rises.
また第3図b下グラフのように上部ダンパ13に比べて
下部ダンパ14を下部通路閉側Hに大きく回すと、下部
通路12を通る冷風量が少なくなりその減少分は加熱器
7により加熱されるので同図上グラフのように上下部温
風の温度差は大きくなる。Further, as shown in the lower graph of FIG. 3b, when the lower damper 14 is turned to the lower passage closing side H more than the upper damper 13, the amount of cold air passing through the lower passage 12 decreases, and the decreased amount is heated by the heater 7. Therefore, as shown in the upper graph of the figure, the temperature difference between the upper and lower warm air becomes large.
第3図cは上記と反対に下部ダンパ14を上部ダンパ1
3に比べて第1図C方向即ち加熱器閉側に位置させて上
下部温風の温度差をなくした例。In Fig. 3c, the lower damper 14 is replaced with the upper damper 1, contrary to the above.
3, this is an example in which the temperature difference between the upper and lower hot air is eliminated by locating the heater in the C direction of FIG. 1, that is, on the closed side of the heater.
第3図dは上下温風の温度差を略一定に保つて共に温度
を上げる場合のダンパ13,14の制御伏態を表わす。
上記のような種々の調整に当りダンパ13,14の位置
が変つても、上下温風の風量割合は殆ど変らない。FIG. 3d shows the control state of the dampers 13 and 14 when the temperature difference between the upper and lower hot air is kept approximately constant and the temperature of both is raised.
Even if the positions of the dampers 13 and 14 change during the various adjustments described above, the ratio of the upper and lower warm air volumes hardly changes.
なお上部ダンパ13は主に上方吐出口2,3への温風、
下部ダンパ14は主に下方吐出口4への温風の温度を制
御することができるから各別制御がよいが、連動的に制
御させることもできる。吐出口2,3、4,5の各温風
量割合調節はダンパ18,21で行う。本発明は、上記
のように上下方温風の温度差を風量バランスを変えるこ
となく行い得る点で前記公知のものに比べて優れている
。The upper damper 13 mainly blows hot air to the upper discharge ports 2 and 3.
Since the lower damper 14 can mainly control the temperature of the hot air flowing to the lower discharge port 4, it is preferable to control each of them separately, but they can also be controlled in conjunction with each other. Adjustment of the hot air volume ratio of each of the discharge ports 2, 3, 4, and 5 is performed by dampers 18 and 21. The present invention is superior to the above-mentioned known systems in that it is possible to adjust the temperature difference between the upper and lower hot air without changing the air volume balance as described above.
上下2枚のダンパのみで調節が行われるから構成操作が
簡単である。また公知例の1枚ダンパの約1/2の長さ
でよいから、風圧によるモーメントが小さく操作性がよ
い。特に上下方向に同時に連動させるようにすると両ダ
ンパ13,14の重量は相殺され変動が少なく操作機構
の構成上有利である。Since adjustment is performed using only two dampers, the upper and lower dampers, the configuration is easy to operate. Furthermore, since the damper only needs to be about 1/2 the length of the known one-piece damper, the moment due to wind pressure is small and operability is good. In particular, if the dampers 13 and 14 are moved simultaneously in the vertical direction, the weights of both dampers 13 and 14 are offset, resulting in less fluctuation, which is advantageous in terms of the structure of the operating mechanism.
