【考案の詳細な説明】
本考案は内気および外気の取入切替機構を有す
る自動車用空調装置の空気取入口構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air intake structure for an automobile air conditioner having an intake switching mechanism for inside air and outside air.
従来、自動車用空調装置に用いられる空気取入
箱は、内気取入用流路と外気取入用流路と間にス
プリング付きのターンオーバ機構を有する１枚の
板状のダンパーが設けられ、内気取入と外気取入
との切替はダンパーの開閉操作によつて行なつて
いる。 Conventionally, an air intake box used in an automotive air conditioner is provided with a single plate-shaped damper having a turnover mechanism with a spring between an inside air intake flow path and an outside air intake flow path. Switching between inside air intake and outside air intake is performed by opening and closing the damper.
しかし、このような内外気切替機構の場合、ダ
ンパーの開閉操作時、スプリングの付勢力に抗し
て荷重をかける必要があるため、操作時の荷重が
大きい問題があり、また構造上通風抵抗が大きく
フアン効率が悪い問題がある。さらに走行時には
外気による風圧によつてダンパーが自然開放する
事態が発生しやすく、したがつてダンパーのシー
ル性が劣るために確実な内外気切替操作が困難で
あるという問題がある。 However, in the case of such an internal/external air switching mechanism, when opening and closing the damper, it is necessary to apply a load against the biasing force of the spring, so there is a problem that the load during operation is large, and the structure also causes ventilation resistance. There is a major problem with fan efficiency. Furthermore, when the vehicle is running, the damper tends to open automatically due to wind pressure from outside air, and the sealing performance of the damper is therefore poor, making it difficult to reliably switch between inside and outside air.
また、車室内と車室外とを仕切る部材に開口部

減させたダンパー装置が提案されている（例え
ば、実開昭54−95757号公報）。 Further, an opening is provided in a member that partitions the vehicle interior and the vehicle exterior, and instead of the plate-shaped damper, a substantially triangular prism hollow damper with two sides open is slidably provided in the opening, A damper device has been proposed in which the ventilation resistance of either the inside air intake channel or the outside air intake channel is reduced (for example, Japanese Utility Model Application Publication No. 54-95757).
ところが、上記ダンパー装置においては、上記
両流路の通風抵抗を同時に低減させることは困難
である。すなわち、内気取入用流路の通風抵抗を

抗を低減させることができず、反対に外気取入用
流路の通風抵抗を低減させようとすると、内気取
入用流路の通風抵抗を低減させることができな
い。 However, in the damper device described above, it is difficult to reduce the ventilation resistance of both the flow paths at the same time. In other words, if you try to reduce the ventilation resistance of the inside air intake channel, you will not be able to reduce the ventilation resistance of the outside air intake channel; on the contrary, if you try to reduce the ventilation resistance of the outside air intake channel. In this case, the ventilation resistance of the inside air intake channel cannot be reduced.
本考案の目的は、内外気切替操作が確実かつ容
易であり、内気取入時の通風抵抗および外気取入

ことができる自動車用空調装置の空気取入口構造
を提供することである。 The purpose of this invention is to provide an air conditioning system for automobiles that can reliably and easily switch between inside and outside air, reduce ventilation resistance when taking in inside air and ventilation resistance when taking in outside air, and improve fan efficiency. The purpose is to provide an intake structure.

る。 In order to achieve the above object, the air intake structure of the automotive air conditioner of the present invention includes a fan, an outside air intake hole on one side and an inside air intake hole on the other side. a hemispherical air intake box having a center on the axis of the fan, and a spherical lid that slides along the inside of the spherical surface of the air intake box to open and close both intake holes. It is equipped with the following.
上記構成によれば、球面状の蓋を空気取入箱の
球面内側に沿つて摺動させると、外気取入用孔と

されて内気のみがフアンに吸引される。 According to the above configuration, when the spherical lid is slid along the spherical inner side of the air intake box, the outside air intake hole and the inside air intake hole are opened or closed. In other words, when the outside air intake hole is opened, the inside air intake hole is closed by the above-mentioned lid and only outside air is sucked into the fan, and conversely, when the inside air intake hole is opened, The outside air intake hole is closed by the lid, and only the inside air is sucked into the fan.

る構造となつている。 In FIGS. 1 and 2, a hemispherical air intake box main body 1 is provided with an outside air intake port 2 extending outside the hemispherical body, and is formed by opening another part of the hemispherical body. An inside air intake port 3 is provided.
The lower edge of the hemispherical body of the air intake box body 1 is connected to the casing 4. A multi-blade fan 5 is mounted inside the casing 4, and is rotated by a blower motor 6 provided outside the casing 4. Further, the air intake box body 1 has a hemispherical lid 7 which is in surface contact with the inner surface of the hemispherical portion of the body and is adapted to rotate around a point indicated by 0 in the figure. That is, a hole is made in the part shown at point 0 of the air intake box body 1, and a rod is inserted into this hole.One end of this rod is fixed to the lid 7, and the other end is fixed to one end of the arm 8. A lever 9 is attached to the other end of the arm 8. In addition,
In the figure, the lid 7 has a structure in which approximately half of the hemisphere forms an opening.

閉鎖することになる。 Next, when switching from outside air intake to inside air intake, by moving the lever 9 in the direction shown by the arrow in the figure, the lid 7 rotates around point 0, closing the outside air intake 2 and closing the outside air intake port 2. Open the inside air intake port 3. Therefore, inside air flows into the space A, and this inside air flows into the casing 4 as the multi-blade fan 5 rotates.
It passes through a flow path B in the interior and is introduced into a heating unit (not shown). In this way, by operating the lever 9, the lid 7 slides on the inner surface of the air intake box body 1, and opens or closes the outside air intake port 2 and the inside air intake port 3, respectively.

できる。 As explained above, according to the present invention, the outside air intake hole and the inside air intake hole formed in the air intake box are provided above the fan, and furthermore, the distance from both the intake holes to the fan is Since it has a substantially linear configuration, it is possible to reduce ventilation resistance both when taking in outside air and when taking in inside air, and fan efficiency is significantly improved. Also, when the lid is closed,
Since the lid will not open even if a force is applied in the vertical direction, it can prevent the lid from opening automatically due to the wind pressure of outside air when taking in air while the vehicle is running, improving the efficiency of heating and cooling inside the vehicle. can. Furthermore, since the lid is adapted to slide in close contact with the inner surface of the air intake box, airtightness can be maintained sufficiently without using a spring or the like to bias the lid against the inner surface of the air intake box.
