Description

本発明は空気調和機に関するものである。 The present invention relates to an air conditioner.

従来、この種の空気調和機は、吸込み口から室内空気を吸込み、これを熱交換器での熱交換によって温度調節をした後、空調風として吹き出し口から室内へ吹き出すようになっているが、横断流送風機のスタビライザによって生じる空気流れの偏流や乱れを減少させて騒音を減少させ、流量性能を向上させる為に、スタビライザに種々の形状工夫を凝らしていた（例えば、特許文献１）。 Conventionally, this type of air conditioner sucks room air from the suction port, adjusts the temperature by heat exchange in the heat exchanger, and then blows it out from the outlet as air-conditioned air. In order to reduce the drift and turbulence of the air flow generated by the stabilizer of the cross flow blower to reduce noise and improve the flow rate performance, various stabilizers have been devised in the stabilizer (for example, Patent Document 1).

図７、図８（ａ）（ｂ）は、特許文献１に記載された従来の空気調和機の室内機の斜視図、横断面図、スタビライザ付近の拡大図を示すものである。図７、図８に示すように、室内機１は、スタビライザ２がファン３の回転方向に延びてファン３との距離が最短となる第１の突端４を具備し、この突端４より先端部にこの突端４と同形状でファン３との距離を上記最短距離より大きくとる第２の突端５をつけることにより、先端部においてスタビライザ２とファン３との干渉音を極力抑えながら、スタビライザ２とファン３の間の空気の漏れ流れをファン３へ円滑に流入でき、流量性能が向上できる。このような方法では、横断流送風機のスタビライザ２によって生じる空気流れの偏流や乱れを減少させて騒音を減少させ、流量性能を向上させるものである。
特開平１０−１６０１８５号公報 FIGS. 7, 8 </ b> A, and 8 </ b> B are a perspective view, a cross-sectional view, and an enlarged view of the vicinity of the stabilizer of the indoor unit of the conventional air conditioner described in Patent Document 1. FIG. As shown in FIGS. 7 and 8, the indoor unit 1 includes a first protruding end 4 in which the stabilizer 2 extends in the rotation direction of the fan 3 and the distance from the fan 3 is the shortest. The second projecting end 5 having the same shape as the projecting end 4 and having a distance from the fan 3 larger than the shortest distance is attached to the stabilizer 2 while suppressing the interference sound between the stabilizer 2 and the fan 3 as much as possible. The air leakage flow between the fans 3 can smoothly flow into the fan 3 and the flow rate performance can be improved. In such a method, the drift and turbulence of the air flow generated by the stabilizer 2 of the cross flow fan are reduced to reduce noise and improve the flow rate performance.

しかしながら、前記従来の構成では、第１の突端４あるいは第２の突端５に吸込み流れが衝突して乱れが生じ、流量性能の向上や騒音低減が抑制される。 However, in the conventional configuration, the suction flow collides with the first protruding end 4 or the second protruding end 5 to cause turbulence, and the improvement in flow rate performance and noise reduction are suppressed.

また、第１の突端４から第２の突端５へと流れが拡散して乱れが大きくなる傾向にある。 Further, the flow tends to diffuse from the first tip 4 to the second tip 5 and the turbulence tends to increase.

さらに、第２の突端５の上部で熱交換器８からの吸込み流れとが衝突して、乱れが助長されるため、同様に流量性能の向上や騒音低減に抑制されることになるといった課題を有していた。 Furthermore, the suction flow from the heat exchanger 8 collides with the upper part of the second tip 5 and the turbulence is promoted, so that the problem is that the flow rate performance is improved and the noise is similarly reduced.
