On the more downstream side, there are also attraction blades 12, 13, 14.
are arranged in this order on the downstream side of the mainstream deflection blade 11.

する様構成・配置されている。 The drive unit 3 has a gear train therein. 10b, 11b, 12b, 13b, 14b
are axes 10a, 11a, 12a, 13, respectively.
This is a gear fixed to a and 14a. 15a-2
0a are fixed shafts, and gears 15b to 20b are rotatably inserted around these shafts. Further, the shaft 11a is also fixed to a knob 21 installed outside the drive unit 3.
The blades 12, 13, and 14, of which these gear trains constitute a drive mechanism 21, are constructed and arranged so as to form a guide wall 22 when the blades 11 are tilted to their maximum by the operation of this gear train.
次に作動を説明する。 Next, the operation will be explained.
今、ギヤトレインの初期状態としてそれぞれの
羽根１０〜１４が第２図の如く設定されている場
合を考える。 Now, let us consider a case where each of the blades 10 to 14 is set as shown in FIG. 2 as the initial state of the gear train.
入口部８より流入する流れＡのうち、主流A1

の設定方向が流れＡとほぼ同一方向ゆえ、直進す
る。これらにより、出口部９を通過した流れは、
流れＡと同一の直進方向の流れＢとなる。 Main stream A 1 of the flow A flowing in from the inlet part 8
travels straight without being deflected by the mainstream deflection blades 11. Further, the bias flow A 2 also travels straight because the bias applying vanes 10 are parallel to the flow A.
Furthermore, the induced flows A 3 , A 4 , A 5 are also
2, 13, and 14 have a small degree of curvature, and their setting direction is almost the same as flow A, so they travel straight. Due to these, the flow passing through the outlet part 9 is
Flow B becomes the same straight direction as flow A.

歯数を少なくしてあるため、羽根１２，１３，１
４の順に、それぞれの下流側における接線方向
は、より下側を向く様に設定される。すなわち、
これらのギヤトレインの動きにより、第４図の如
き羽根の設定状態が得られる。 Next, rotate the knob 21 counterclockwise. At this time, gear 11b rotates 10b counterclockwise via 15b, 16b, and 17b;
Since the number of teeth in blade 1 is smaller than the number of teeth in blade 11b, blade 1
0 is more inclined than the blade 11. On the other hand, the gear 11b connects the gear 12b via the gear 18b.
Further, the gear 13b is rotated counterclockwise via the gear 19b, and the gear 14b is rotated counterclockwise via the gear 20b. The number of teeth at this time is 12b and 11
Since b is made equal, the tangential direction on the downstream side of the blade 12 points lower than the direction of the blade 11. Also, since the gears 12b, 13b, and 14b have fewer teeth in this order, the blades 12, 13, and 1
In the order of No. 4, the tangential direction on each downstream side is set to face more downward. That is,
These gear train movements result in the vane settings as shown in FIG.
入口部８より流入する流れＡのうち、主流A1

ため、順次合流して１つの円弧状流れを形成する
と共に、これらすべてが、羽根１１よりも下方を
向くため、全体として、主流A1を下方偏向すべ
く作用する。 Main stream A 1 of the flow A flowing in from the inlet part 8
is directed slightly downward by the mainstream deflection blade 11. Bias flow A 2 is bias addition vane 1
0 is facing downwards than the blade 11, so the mainstream
It acts to deflect A 1 downward. Furthermore, the induced flows A 3 , A 4 , A 5 are induced by the induced flow blades 12 , 13 , 14
Since the tangential angles at the downstream ends of the A 1 point sequentially downward, they sequentially merge to form one arc-shaped flow, and all of these points downward relative to the blade 11, so that the main flow A 1 as a whole is directed downward. It acts to deflect.
これらにより、出口部９を通過した流れは、流
れＡより下方に偏向した流れＢとなる。 As a result, the flow that has passed through the outlet portion 9 becomes a flow B that is deflected downward from the flow A.
次に、つまみ２１を更に反時計方向に回転し、
主流偏向用羽根１１が最大傾斜角に設定されたと

根１０は、第４図の設定より更に反時計方向に回
転される。 Next, rotate the knob 21 further counterclockwise,
It is assumed that the mainstream deflection blade 11 is set to the maximum inclination angle. At this time, the gear train has blades 12, 13,
14 is set so as to form a curved guide wall as shown in FIG. Further, the biasing blade 10 is rotated further counterclockwise than the setting shown in FIG.
入口部８より流入する流れＡのうち、主流A1

場合、誘引流れは、羽根１２，１３，１４が流路
を閉鎖するため形成されないが、この案内壁２２
が、主流A1の付着効果を生じさせる。 Main stream A 1 of the flow A flowing in from the inlet part 8
is largely directed downward by the mainstream deflection blades 11. The bias flow A2 is caused by the fact that the biasing blade 10 faces downward from the blade 11.
It acts to deflect A 1 further downward. In this case, no induced flow is formed because the vanes 12, 13, and 14 close the flow path, but the guide wall 22
causes the adhesion effect of mainstream A1 .
これらにより、出口部９を通過した流れは、流
れＡより大きく下方に偏向した流れＢとなる。 As a result, the flow that has passed through the outlet section 9 becomes a flow B that is deflected more downward than the flow A.

により流れに対する大きな風量低下をきたすこと
なく、広角の偏向が可能となる。Effects of the Invention As explained above, in the present invention, a large reduction in air volume can be achieved by deflecting the main flow using a plurality of rotatable blades around an axis arranged at the outlet of the flow, and by using the effects of bias flow and induced flow. Wide-angle deflection is possible without causing any damage.
また、主流偏向用羽根の最大傾斜時に、誘引用
羽根で曲面状案内壁を形成することにより、さら
に広角の偏向が達成される。 Furthermore, by forming a curved guide wall with the guiding blades when the main stream deflecting blades are at their maximum inclination, an even wider angle of deflection can be achieved.
