【考案の詳細な説明】
本案は空気調和機等に用いられる風向変更装置に関し、
特に風向変更体が自重で自然に回動するのを防止しつつ
、スムーズにこの風向変更体を回動操作できるように図
ったものである。[Detailed description of the invention] This invention relates to a wind direction changing device used in air conditioners, etc.
In particular, the wind direction changing body is designed to be able to be rotated smoothly while preventing the wind direction changing body from rotating naturally due to its own weight.
従来、第1図に示す壁掛型空気調和機1の空気吹出開口
2には、例えば第2図及び第3図にその詳細を示すよう
に空気吹出開口2の両側に設けられ軸穴3,3を有した
軸受板5′、6と、軸受穴3,3に嵌入される回転軸7
,8を有しかつ重心が軸心よりも高所に位置させて前下
方へ回動自在に支持される風向変更体9と、回転軸7と
連動し遊端が軸受板5′に弾性当接し風向変更体9を任
意の回動位置に保持するように回転軸7の先端に固定さ
れるバネ板10とからなる風向変更装置を備えている。Conventionally, the air outlet 2 of the wall-mounted air conditioner 1 shown in FIG. 1 has shaft holes 3, 3 provided on both sides of the air outlet 2, as shown in detail in FIGS. 2 and 3, for example. bearing plates 5', 6 having
, 8 and whose center of gravity is located higher than the axis and is supported rotatably forward and downward; The airflow direction changing device includes a spring plate 10 fixed to the tip of the rotating shaft 7 so as to hold the airflow direction changing body 9 in any rotational position.
尚、風向変更体9の一方の軸7は第2図に示す如く軸7
周囲の間隔子11とバネ板10との作用により風向変更
体9が軸方向へ移動しないように支持され、他方の軸8
は単に軸穴に嵌入されているだけである。Incidentally, one shaft 7 of the wind direction changing body 9 is connected to the shaft 7 as shown in FIG.
The wind direction changing body 9 is supported so as not to move in the axial direction by the action of the surrounding spacer 11 and the spring plate 10, and the other shaft 8
is simply inserted into the shaft hole.
斯る構成の風向変更装置においては、風向変更体9の重
心がこの風向変更体の軸心よりも高所に位置している。In the wind direction changing device having such a configuration, the center of gravity of the wind direction changing body 9 is located higher than the axis of the wind direction changing body.
従って、風向変更体9が前下方へ傾斜すればする程、風
向変更体の自重でこの変更体が前下方へ回動する虞れが
あります。Therefore, the more the wind direction changing body 9 is tilted forward and downward, the more the wind direction changing body 9 is likely to rotate forward and downward due to its own weight.
しかも風向変更体は前下方への傾斜角が大きくなるにつ
れて回動力が徐々に増加して回動し易くなる。Furthermore, as the angle of inclination toward the front and lower sides of the wind direction changing body increases, the rotational force gradually increases, making it easier to rotate.
これに対し従来は、単にバネ板10で軸受板5′を押圧
させていた。In contrast, in the past, the bearing plate 5' was simply pressed by the spring plate 10.
従ってバネ板10の押圧力が弱いと微振動並びに自重に
より風向変更体9はその自重により第3図イの状態から
回動して第3図口の状態になる虞れがある。Therefore, if the pressing force of the spring plate 10 is weak, there is a risk that the wind direction changing body 9 will rotate from the state shown in FIG.
この為回動を防止するにはバネ板10のバネ力を強くし
たり或いはバネ板10の遊端が摺動する軸受板5′の部
分にボッチを設けたりしていた。Therefore, in order to prevent rotation, the spring force of the spring plate 10 has to be increased, or a notch has been provided in the portion of the bearing plate 5' on which the free end of the spring plate 10 slides.
しかしながら前者の方式ではバネ板10のバネ力が強く
なり過ぎて風向変更体9の回動に支障をきたす虞れがあ
り、後者の方式ではボッチの為に風向変更体9の回動が
段階的となっていた。However, in the former method, there is a risk that the spring force of the spring plate 10 becomes too strong, which may interfere with the rotation of the wind direction changing body 9, and in the latter method, the rotation of the wind direction changing body 9 is gradual due to the bocce. It became.
このようにいずれの構造に於いても風向変更体9をスム
ーズに前下方へ傾斜させることができない欠点があった
。As described above, both structures have the disadvantage that the wind direction changing body 9 cannot be smoothly tilted forward and downward.
本案は斯る点に鑑みなされたもので、軸受板5のバネ板
10が摺動当接する部分の板厚を風向変向体9の前方へ
の傾斜角が大きくなるにつれて徐々に厚くしたもので、
第4図に示す実施例では軸受板5の板厚を全体に亙って
寸法1−1+αと徐々に厚くしているが、バネ板10の
摺動当接部のみに限定して厚くしても良い。The present invention was developed in view of this point, and the thickness of the portion of the bearing plate 5 where the spring plate 10 comes into sliding contact is gradually increased as the forward inclination angle of the wind direction deflector 9 increases. ,
In the embodiment shown in FIG. 4, the thickness of the bearing plate 5 is gradually increased to a dimension of 1-1+α over the entire area, but the thickness is increased only in the sliding contact portion of the spring plate 10. Also good.
すなわち風向変更体9の重心をこの風向変更体の軸心よ
りも高所に位置させ、且つ軸受板5のバネ板10が当接
する部分の板厚を徐々に厚くしたので、バネ板10の押
圧力と風向変更体9の回動力とを相殺することにより自
重でこの変更体が自然に回動するのを防止しつつ一定の
力でスムーズに風向変更体9を回動操作することができ
る。That is, the center of gravity of the wind direction changing body 9 is located higher than the axis of the wind direction changing body, and the thickness of the portion of the bearing plate 5 that the spring plate 10 comes into contact with is gradually increased, so that the spring plate 10 is not pushed. By offsetting the pressure and the rotational force of the wind direction changing body 9, the wind direction changing body 9 can be rotated smoothly with a constant force while preventing the changing body from rotating naturally due to its own weight.
従って、本案によれば風向変更体9は従来と同様にスム
ーズに前下方へ回動可能となると共に、風向変更板9の
前方への傾斜角が大きくなるにつれてバネ板10による
押圧力が強くなるので、機器の運転中に微振動等で風向
変更体9が勝手に回動することがなくなり、又風向変更
体9の前下方への回動動作を常に一定の力でスムーズに
行なわせることができる等実用的価値が大きい。Therefore, according to the present invention, the wind direction changing body 9 can be smoothly rotated forward and downward as in the conventional case, and as the forward inclination angle of the wind direction changing plate 9 increases, the pressing force by the spring plate 10 becomes stronger. Therefore, the wind direction changing body 9 will not rotate freely due to slight vibrations etc. while the equipment is operating, and the forward and downward rotation of the wind direction changing body 9 can always be performed smoothly with a constant force. It has great practical value.
尚、風向変更体9が左右に移動しないように軸受板5,
6に支持する構造は第1図〜第3図に示すものに限定さ
れない。Note that the bearing plate 5,
6 is not limited to the structure shown in FIGS. 1 to 3.
