この発明は空気調和機の風向変更装置に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a wind direction changing device for an air conditioner.
従来の技術
従来、この種の空気調和機は第４図、第５図に示される
ような構成になっていた。2. Description of the Related Art Conventionally, this type of air conditioner has been constructed as shown in FIGS. 4 and 5.

状のものよシ形成されている。In the figure, 1 is the main body of the indoor unit, and the suction port 2a
A front grille 2 is provided with an air outlet 2b, and air outlet grilles 1 and 3 are provided with a rectangular air outlet passage 3a having short sides and long sides. Reference numeral 4 denotes a ventilation circuit formed between the main body 1 and the front grille 2, which communicates with the suction port 2a and the blowout passage 3a, and has a heat exchanger forming a part of the refrigeration cycle inside. 5 and a blower 6 are provided. 7
That's the speech bubble! Vertical wind direction changing blades whose ends are rotatably incorporated in the left and right side walls, which are the short sides of J/m/3, and 8 are a plurality of vanes rotatably incorporated into the long side surfaces of the outlet grille 3. The left and right wind direction changing blades are shaped like flat plates as shown in Figure 5.
発明が解決しようとする問題点
しかし、このような構造のものでは、吹出グルｌＶ３の
内を通過する風を左右へ大きく偏向する場合に、吹出口
２ｂの巾が変わらないこと、および風を左右風向変更羽
根８へ衝突きせることがら風量の低下が大きく、左右の
偏向角度があまり大きくできない問題があった。Problems to be Solved by the Invention However, with such a structure, when the air passing through the air outlet glue lV3 is largely deflected to the left and right, the width of the air outlet 2b does not change and the wind is deflected from side to side. There was a problem in that the air volume was greatly reduced due to collision with the wind direction changing blade 8, and the left and right deflection angle could not be made very large.
これは第５図に示すように、風上側より、吹出グリル３
内の吹出流路３ａを通過した風が、平板状の左右風向変
更羽根８に当たり、強制的に左右へ偏向された後、吹出
グリ）し３の左右両端壁に当たって抵抗が大きくなるだ
めである。このことは風量が減少することになり、これ
に起因して例えば暖房、冷房の能力の低下にも影響する
。As shown in Figure 5, this is done from the windward side of the outlet grille 3.
The wind that has passed through the air outlet channel 3a hits the flat left and right wind direction changing vanes 8, is forcibly deflected to the left and right, and then hits the left and right end walls of the air outlet 3, increasing resistance. This results in a decrease in air volume, which also affects, for example, a decrease in heating and cooling capacity.
そこで本発明は風を左右へ大きく偏向しても、風が吹出
グリル３の左右両端壁に当って減少するのを防ぎ、さら
に大きな左右の風向偏向角度が得られるようにするもの
である。Therefore, the present invention prevents the wind from hitting the left and right end walls of the outlet grille 3 and reducing the wind even if the wind is largely deflected to the left and right, thereby making it possible to obtain an even larger left and right deflection angle of the wind.
問題点を解決するための手段
上記問題点を解決するだめの本発明の技術的手段は、吹
出グリルの左右両端壁を吹出方向に広がる曲線壁とし、
吹出口の出口面積を拡大したものである。Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is that both left and right end walls of the outlet grill are curved walls that spread in the direction of the outlet;
This is an enlarged outlet area of the air outlet.
作 用 この技術的手段による作用は次のようになる。For production The effect of this technical means is as follows.
すなわち、左右風向変更羽根により、風を偏向する場合
、本発明では、吹出口を通過する風は左右風向変更羽根
により偏向され、その後の風は吹出グリルの左右両端壁
への当シが少なくなシ、左右へ大きく偏向される。そし
て風量の損失も少なくできる。That is, when the wind is deflected by the left and right wind direction changing blades, in the present invention, the wind passing through the outlet is deflected by the left and right wind direction changing blades, and the subsequent wind is less likely to hit the left and right end walls of the outlet grille. It is deflected greatly to the left and right. Also, the loss of air volume can be reduced.
実施例
以下、本発明の一実施例について、図面第１図〜第３図
に基づき説明する。ここで、従来例と同じものについて
は同じ符号を付して説明を省略する。EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3 of the drawings. Here, the same parts as in the conventional example are given the same reference numerals and the description thereof will be omitted.
同図において、９は吹出グリルａ内の吹出流路３ａへ回
動可能に設けられた左右風向変更羽根で、第１図の如く
円弧形状に形成されている。前記吹出グリル３の左右両
側壁３ｂは、左右風向変更羽根９の曲線部の方向に合わ
せて吹出口方向に向けて順次広がっている。前記左右風
向変更羽根９がわん曲しているのは、左右両側壁３ｂの
わん曲とあわせて周知の如くコアンダ効果によって風向
きを変更するためである。In the figure, reference numeral 9 denotes a left-right wind direction changing blade rotatably provided in the blow-off passage 3a in the blow-off grille a, which is formed in an arc shape as shown in FIG. The left and right side walls 3b of the outlet grille 3 gradually widen toward the outlet in accordance with the direction of the curved portion of the left and right wind direction changing blades 9. The reason why the left and right wind direction changing blades 9 are curved is to change the wind direction by the well-known Coanda effect together with the curves of the left and right side walls 3b.
そして、本発明の効果を具体的に示すものとして従来例
と実施例の場合の、風の偏向角度と風量低下率の関係を
示す実験結果を第３図に示す。As a concrete demonstration of the effects of the present invention, FIG. 3 shows experimental results showing the relationship between the wind deflection angle and the air volume reduction rate in the conventional example and the example.
この結果から明らかなように、送風機（風上側）から送
られてきた風が吹出流路３ａ内で左右風向変更羽根９に
よって左右へ偏向される場合、吹出口の左右両側壁３ｂ
に沿って風下側へ流れていくことになり、風景の低下が
大幅に改善される。As is clear from this result, when the wind sent from the blower (windward side) is deflected to the left and right by the left and right wind direction changing blades 9 within the blowout channel 3a, the left and right side walls 3b of the blowout outlet
The river will flow to the leeward side along the river, which will greatly improve the deterioration of the landscape.
なお、本実施例においては、コアンダ効果によって風向
きを変えるように構成したが、従来の如□く平板状の左
右風向変更羽根によって強制的に風向きを変えるように
しても同様の効果が期待できる。In this embodiment, the wind direction is changed by the Coanda effect, but the same effect can be expected even if the wind direction is forcibly changed using flat left and right wind direction changing blades as in the past.
発明の効果
以上のように、本発明は吹出グリルの左右両側壁を吹出

時の節電を高める効果も得られる。Effects of the Invention As described above, the present invention expands the area of the outlet by forming the left and right side walls of the outlet grill into curved walls that spread in the outlet direction, thereby increasing the left and right deflection angle of the air, and reducing the amount of air flow in that case. It will be extremely rare. This significantly improves the feeling during heating and cooling operation, and also provides the effect of increasing power savings during heating.
