御し、吹出口１８を流出する流れの偏向を制御する。The downstream end inner wall of the integrated casing 15 is provided with a thick arc-shaped constriction curved surface so that the flow is smoothly constricted. Reference numeral 16 denotes a guide blade which is provided before and after the rotary blade 11 and whose cross section is in the shape of an arcuate blade.
5 is fixed on the wall surface by a support rod 17. The flow exiting the rotary blade 11 is converted into a bias flow directed toward the central axis by the lower guide blade 16, and is rectified by a flow path consisting of the guide blade 16 and the arc-shaped constriction curved surface of the integrated casing 15, and then flows downstream. The air is guided to an air outlet 18 provided on the side. 19 is the rotor blade 1
The bias flow is controlled by a control plate which has the same diameter as the outer diameter of the ponnu part of 1 and is movable in any direction and at any height by a drive device 20 supported and fixed at the center by the support rod 17, The deflection of the flow exiting the outlet 18 is controlled.
前記吹出口１８の下流側には漸次拡大形状を有する案内
壁２１が設けられている。A guide wall 21 having a gradually expanding shape is provided on the downstream side of the air outlet 18 .
以上のように構成された風向制御型送風機について、以
下第２図から第５図を用いてその動作原理を説明する。The principle of operation of the wind direction control type blower configured as described above will be explained below with reference to FIGS. 2 to 5.
まず第２図は風向制御型送風機の断面図を示すものであ
って、制御板１９が吹出口１８上流端面左側上に接触し
ている場合について説明する。この場合、回転翼１１に
よって送り出された流れＦ。First, FIG. 2 shows a sectional view of the wind direction control type blower, and the case where the control plate 19 is in contact with the upper left side of the upstream end surface of the air outlet 18 will be described. In this case, the flow F delivered by the rotor 11.
は一体型ケーシング１５に沿って流れ、案内翼１６軸方
向へ向かうバイアス流（向心流）ＦＢとなる。flows along the integrated casing 15 and becomes a bias flow (centripetal flow) FB directed toward the axial direction of the guide vane 16.
ここで図の左側においてもバイアス流が発生するが、吹
出口１８上流端面に接触している制御板１９の遮蔽効果
により、バイアス流ＦＢは遮られる。Here, a bias flow also occurs on the left side of the figure, but the bias flow FB is blocked by the shielding effect of the control plate 19 that is in contact with the upstream end surface of the air outlet 18.
このため吹出口１８から出る流れＦＡは図の右側からの
バイアス流ＦＢの作用により押されて左側の案内壁２１

２人は案内壁２１と干渉しコアンダ効果によって案内壁
２１面上に沿って流れ、風量低下をほとんど引き起こさ
ずに大きく偏向される。この場合、最大偏向角度は案内
壁２１の形状によって任意に設定できる。Therefore, the flow FA coming out of the air outlet 18 is pushed by the action of the bias flow FB from the right side of the figure, and is pushed toward the left guide wall 22.
bent to the side. As a result, the two flows coming out of the air outlet 18 interfere with the guide wall 21, flow along the surface of the guide wall 21 due to the Coanda effect, and are largely deflected with almost no reduction in air volume. In this case, the maximum deflection angle can be arbitrarily set depending on the shape of the guide wall 21.
次に第３図に示すように、制御板１９を吹出口１８上流
端面右側で接触させた場合について説明する。この場合
、図の右側のバイアス流ＦＢが遮られ、吹出口１８から
出る流れ２人は右側に傾き、右側の案内壁２１に沿って
右側に大きく偏向される。Next, as shown in FIG. 3, a case will be described in which the control plate 19 is brought into contact with the right side of the upstream end surface of the air outlet 18. In this case, the bias flow FB on the right side of the figure is blocked, and the two flows exiting from the air outlet 18 are inclined to the right side and are largely deflected to the right side along the right guide wall 21.
すなわち、制御板１９の遮蔽位置に応じて、遮蔽位置の
存在する方向に流れは広角に偏向することになる。That is, depending on the shielding position of the control plate 19, the flow is deflected over a wide angle in the direction of the shielding position.
また、流れＦＱよりも上流の流れについては全て第２図
と同一であるため、以下は省略する。Furthermore, since all the flows upstream of the flow FQ are the same as those in FIG. 2, the following description will be omitted.
次に第４図に示すように、制御板１９をわずかに持ち上
げ、吹出口１８上流端面と制御板１９の間に小さな間隙
ｄを設けた場合について説明する。Next, as shown in FIG. 4, a case will be described in which the control plate 19 is slightly lifted and a small gap d is provided between the upstream end surface of the air outlet 18 and the control plate 19.
この場合、このわずかな間隙を通過する流れＦ”ｎｔ。In this case, the flow F"nt passes through this small gap.

ことによって、流れの偏向角度を任意に設定することが
できる。is generated, and due to this action, the flow FA exiting from the outlet 18
The tilting force of becomes smaller. As a result, the degree of adhesion to the guide wall 21 also decreases, and the deflection angle also becomes smaller compared to FIG. 3. As the gap d is gradually increased, the deflection angle of the flow gradually becomes smaller, and eventually the deflection angle reaches zero as shown in Figure 5. . That is, by changing the height d of the control plate 19, the deflection angle of the flow can be arbitrarily set.
