、4は渦安定板、5は背面ガイダ、6はフィルタ、7は
熱交換器、8は内側底板である。That is, 1 is an outer box, 2 is a front grill, 3 is a cross-flow fan, 4 is a vortex stabilizer, 5 is a back guider, 6 is a filter, 7 is a heat exchanger, and 8 is an inner bottom plate.
以上の様な構成において、貫流ファン3を矢印a方向に
回転させると、矢印すの如く渦が発生し、矢印Cの如く
、吸入口21及びフィルタ6を通って空気が吸入されて
、熱交換器7で熱交換され、貫流ファン3を貫流して、
吸出し口22から吸出される。In the above configuration, when the cross-flow fan 3 is rotated in the direction of the arrow a, a vortex is generated as shown by the arrow A, and air is sucked through the suction port 21 and the filter 6 as shown by the arrow C, and heat exchange is performed. The heat is exchanged in the vessel 7 and flows through the once-through fan 3.
It is sucked out from the suction port 22.
しかし、破線dで囲まれる領域付近では流速が遅く、時
には矢印eで示す様に流れが逆流する場合が見られる。However, the flow velocity is slow near the area surrounded by the broken line d, and sometimes the flow reverses as shown by the arrow e.
従って、従来においては、破線dの領域付近の熱交換器
7においては熱交換量が極めて少なかった。Therefore, conventionally, the amount of heat exchanged in the heat exchanger 7 near the area indicated by the broken line d was extremely small.
又、騒音に関しては、矢印eの如く逆流のために渦が発
生し騒音は大きくなるという欠点があった。Further, regarding noise, there is a drawback that vortices are generated due to the backflow as shown by arrow e, and the noise becomes louder.
本考案は以上の様な欠点をなくシ、熱交換器全体にわた
って均一な高い熱交換量を保ち、しかも低騒音の空気調
和機を提供することを目的とするものである。The object of the present invention is to eliminate the above-mentioned drawbacks, maintain a uniform high heat exchange amount throughout the heat exchanger, and provide an air conditioner with low noise.
以下本考案の一実施例を第2図に基いて説明する。An embodiment of the present invention will be described below with reference to FIG.
なお第1図に示す従来例と同様の部分は共通番号を付し
た。Note that parts similar to those in the conventional example shown in FIG. 1 are given common numbers.
31は第1の貫流ファン、41は第1の渦安定板である
。31 is a first cross-flow fan, and 41 is a first vortex stabilizer.
32は第2の貫流ファンであり、熱交換器7の下部に対
向して設けられている。32 is a second cross-flow fan, which is provided opposite to the lower part of the heat exchanger 7.
42は第2の渦安定板である。42 is a second vortex stabilizer plate.
以上の様な構成において次に本考案の作用を説明すると
、第1図に示した従来例と異なるのは、第2の貫流ファ
ン32によって矢印C1に示す流れが生じ、これが第1
の貫流ファン31による矢印Cの流れと合流して吹出し
口22から吹出すことである。Next, the operation of the present invention in the above-described configuration will be explained. What is different from the conventional example shown in FIG.
This is to merge with the flow of arrow C caused by the cross-flow fan 31 and blow out from the outlet 22.
従って、従来の様に熱交換器を通過する一部の風の流速
が遅くなることがなく、熱交換器全体にわたって均一な
流れを得ることができる。Therefore, the flow velocity of a part of the air passing through the heat exchanger does not become slow as in the conventional case, and a uniform flow can be obtained throughout the heat exchanger.
その結果、熱交換器全体にわたって均一な熱交換量を得
ることができ、逆流などもなく騒音低下となる。As a result, a uniform amount of heat exchange can be obtained throughout the heat exchanger, and there is no backflow and noise is reduced.
又、第1の貫流ファン31の一部に第2の貫流フアン3
2を通過した調和空気が流入するため、吹出し口では、
良好な圧力特性が得られる。Further, a second cross-flow fan 3 is provided in a part of the first cross-flow fan 31.
Since the conditioned air that has passed through 2 flows in, at the outlet,
Good pressure characteristics can be obtained.
従って、吹出し側にも熱交換器を置くことが可能となり
、熱交換量を増大でき、その上、吹出し側熱交換器の整
流作用により、吹出し騒音も低下することができる。Therefore, it is possible to place a heat exchanger on the blowout side as well, increasing the amount of heat exchange, and furthermore, the blowout noise can be reduced due to the rectification effect of the blowout side heat exchanger.
更に、吹出し側熱交換器の遮音効果により、貫流ファン
外周近くで発生する後流孔れによる騒音も下げることが
できる。Furthermore, due to the sound insulation effect of the blow-out side heat exchanger, noise caused by wake holes generated near the outer periphery of the once-through fan can also be reduced.
以上の様に本考案の空気調和機によれば、第1の渦安定
板と背面ガイダを備えた第1の貫流ファンの吸入側に熱
交換器を備え、且つ、この吸入側で、第1の貫流ファン

を備えかつ第1の貫流ファンと同一方向に送風する第2
の貫流ファンを配設している。As described above, according to the air conditioner of the present invention, a heat exchanger is provided on the suction side of the first once-through fan provided with the first vortex stabilizer plate and the back guider, and the first cross-flow fan is provided with the heat exchanger on the suction side. A second vortex stabilizer plate is provided at a slow flow rate portion between the once-through fan and the heat exchanger, and the second vortex stabilizer plate blows air in the same direction as the first once-through fan.
A once-through fan is installed.
従って、熱交換器全体にわたって均一した風量により均
一した熱交換量を得ることができ、空気調和機の能力を
向上させることができる。Therefore, a uniform amount of heat exchange can be obtained by making the amount of air uniform over the entire heat exchanger, and the performance of the air conditioner can be improved.

能力向上が可能となる。In addition, 1. Since the air flowing out from the second once-through fan flows in, it is possible to obtain good pressure characteristics at the outlet. Therefore, sound insulating materials, heat exchangers, etc. are installed on the outlet side to reduce noise and improve the air conditioner. It becomes possible to improve the ability of
さらに第1の貫流ファンと熱交換器との間に空気流の逆
流部分がなくなるため、騒音の低下を図ることができる
。Furthermore, since there is no reverse flow of air between the first once-through fan and the heat exchanger, noise can be reduced.
