本発明は車輌用空気調和装置に関し、特に自動車の天井
下面に設置される自動車用空気調和装置に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vehicle air conditioner, and more particularly to a vehicle air conditioner installed under the ceiling of a vehicle.
従来の技術
従来、自動車の天井下面に設置される自動車用空気調和
装置としては、その送風機に遠心力ファンを用い、装置
の前面に吹出口を有したものだけであった（例えば実開
昭６３−２２２１３号公報、実開昭６３−２４０１１号
公報）。Conventional Technology Conventionally, the only automotive air conditioners installed under the ceiling of a car were those that used a centrifugal fan as the blower and had an air outlet at the front of the device (for example, -22213 Publication, Utility Model Application Publication No. 63-24011).
発明が解決しようとする課題
しかしながら遠心力ファンを送風機として用いる場合に
は、装置の高さ方向の厚みを薄くするのに限界があった
。すなわち遠心力ファンは、その回転軸に垂直な端面か
ら空気を吸い込み、遠心力を利用して外周から空気を吹
き出す構成なのでファン直径をあまり小さくすることが
できない。Problems to be Solved by the Invention However, when using a centrifugal fan as a blower, there is a limit to reducing the thickness of the device in the height direction. In other words, since a centrifugal fan sucks in air from an end face perpendicular to its rotation axis and blows out air from the outer periphery using centrifugal force, the fan diameter cannot be made very small.
従ってファンの回転軸を水平方向にした場合（実開昭６
３−２２２１３号公報）にはファンの直径およびこのフ
ァンを覆うファンケーシングの厚さが必要となってしま
う。Therefore, if the rotation axis of the fan is set horizontally (
3-22213) requires the diameter of the fan and the thickness of the fan casing that covers the fan.
また遠心力ファンの回転軸方向の幅の最適値は、一般に
はファンの半径と同じである。従ってファンの回転軸を
垂直方向にした場合（実開昭６３−２４０１１号公報）
でもファンの径に比例したある程度の幅が必要であると
ともに、このファンを駆動するモータが軸方向に必要で
ある。Further, the optimum value of the width of the centrifugal fan in the direction of the rotating shaft is generally the same as the radius of the fan. Therefore, when the rotation axis of the fan is set in the vertical direction (Utility Model Application No. 63-24011)
However, a certain width proportional to the diameter of the fan is required, and a motor to drive the fan is required in the axial direction.
一方自動車の天井高さは、空気抵抗や車体の安定性等の
問題から一定の高さに制限されるため、車室の空間を広
くとるという点で空気調和装置の高さ方向の厚みを薄く
することは重要である。On the other hand, the ceiling height of automobiles is limited to a certain height due to issues such as air resistance and stability of the vehicle body, so in order to increase the space inside the vehicle, the thickness of the air conditioner in the height direction is reduced. It is important to do so.
一方上記のような従来の車輌用空気調和装置では、本体
装置の前方向には送風することができ、また、吹出口に
取り付けられた羽根の向きを変化させることにより、送
風する方向を左右にも変えることができたが、装置の斜
め下方向へは送風することができなかった。On the other hand, in the conventional air conditioner for vehicles as described above, air can be blown in the front direction of the main unit, and by changing the direction of the blades attached to the outlet, the direction of air can be changed from left to right. However, it was not possible to blow air diagonally downward from the device.
加えて、上記の従来の車輌用空気調和装置に用いられる
遠心力ファンおよびそれを駆動するモータは、前述した
通り大型のものでなくてはならないため、ファンおよび
モータの振動を防止し安定した送風を実現しようとした
場合、ケースの剛性を大きくする必要があり、すなわち
、空気調和装置自体が大型化してしまう。In addition, the centrifugal fan used in the conventional vehicle air conditioner and the motor that drives it must be large, as mentioned above, so vibrations of the fan and motor can be prevented and stable air flow can be achieved. In order to realize this, it is necessary to increase the rigidity of the case, which means that the air conditioner itself becomes larger.
そこで本発明は、まず車輌用空気調和装置の薄型化を目
的とする。Therefore, the first object of the present invention is to reduce the thickness of a vehicle air conditioner.
また本発明は、薄型の車輌用空気調和装置において、十
分な風量を確保し快適な空調を行うことができる車輌用
空気調和装置を提供することを目的とする。Another object of the present invention is to provide a thin vehicular air conditioner that can ensure sufficient air volume and perform comfortable air conditioning.
また本発明は、薄型の車輌用空気調和装置において、本
体装置の斜め下方向に、十分な風量で送風することがで
きる車輌用空気調和装置を提供することを目的とする。Another object of the present invention is to provide a thin vehicular air conditioner that can blow air diagonally downward from the main unit with a sufficient amount of air.
また本発明は、薄型の車輌用空気調和装置であって、か
つファン、モータの振動を抑え十分な風量で安定した送
風を行える車輌用空気調和装置を提供することを目的と
する。Another object of the present invention is to provide a thin vehicular air conditioner that can suppress vibrations of the fan and motor and stably blow air with a sufficient amount of air.

If this distance t' is made too short, a whistling sound will occur. As mentioned above, the present invention aims to increase the air blowing efficiency by ensuring a sufficient amount of air volume and making the wind speed constant over the entire area of the air outlet, and aims to achieve this object in a thin vehicle air conditioner. It is said that Therefore, in a thin vehicle air conditioner, it is important to set the optimum distance between the cylindrical impeller 5 and the first peak 9 and a range of this distance that does not cause any practical problems. In conducting this experiment, the same cylindrical impeller was used as the one used in the previous experiment, and the stabilizer 7 was also of the same shape as that used in the previous experiment. changed the distance between.

（矢印ｄ、矢印ｅ）。Next, the flow of air inside the device will be explained using FIG. 7. First, air sucked in from the suction port 3 is heat exchanged by the evaporator 4, and the heat-exchanged air flows across the cylindrical impeller 5 and then is blown out from the blowout port 2. At this time, part of the wind that has passed through the cylindrical impeller 5 near the upper diffuser 14 is transferred to the guide surface of the protrusion 18.
Although the air is blown towards the front of the device body instead of along line 9 (
Arrow a), almost all the wind passing near the upper diffuser 14 is separated from the curved surface of the upper diffuser 14 by the protrusion 8 and deflected diagonally downward (arrow b shown in Fig. 3).
, arrow c). The wind passing from the lower diffuser 8 of the air outlet 2 near the center of the blade 17 is blown out diagonally downward due to the influence of the wind blowing out diagonally downward as shown by arrows b and c (arrow d and arrow e). ).

That is, by making the upper and lower deflection blades 15 at a sufficiently large angle with respect to the horizontal plane (approximately 50° to 55° with respect to the horizontal plane), it is possible to blow out more downwardly, and by making the upper and lower deflection blades horizontal, It also becomes possible to blow air horizontally.
