The present invention relates to a flow direction control device for deflecting and blowing a flow from an air source in an arbitrary direction.

が望ましい。Conventional configuration and its problems In air conditioners that perform cooling and heating, the direction of air flow is controlled to blow downward during heating and horizontally during cooling, in order to equalize the temperature distribution in the room being air conditioned. This is desirable. Further, due to the installation position of the air conditioner, etc., it is desirable to deflect the light over a wide angle in the left and right directions.

形状でもあるため、壁面への付着効果を悪化させ
ることは免れないという欠点を有していた。 Figures 1 and 2 show conventional examples of achieving this purpose.
There is one shown in the figure. In the figure, 1a and 1b are guide walls (only two are shown in the figure, but there are many), 2 is a nozzle that blows out the flow,
3 is a deflection plate rotated by a shaft 4; Due to the flow guiding action of this deflection plate 3, the flow exiting from the nozzle is directed to the guide walls 1a, 1b (1a in FIG. 1).
It adheres to and is deflected. When the deflection plate 3 is rotated, the guide wall to which the flow adheres changes, and the blowing direction changes. The above operation deflects the flow, but since the deflection plate 3 is installed in the flow path, it creates resistance to the flow and also has a shape that disturbs the streamlines of the flow, so it may not adhere to the wall surface. This has the disadvantage that it inevitably deteriorates the effect.

By rotating around an axis, the position at which part of the flow is blocked can be varied, and by moving in the axial direction of the flow path, the amount at which part of the flow is blocked can be varied.

Furthermore, the position of the flow adhering to the guide wall changes according to the movement of the bias shielding plate, making it possible to arbitrarily change the direction of the flow.

It becomes possible to blow air in an intermediate direction between the front direction and the maximum deflection direction. As a result, balloons can be generated in all directions three-dimensionally. Further, in this case, since the bias shielding plate exists on the upstream side of the nozzle, it does not act as a resistance to the flow and does not disturb the flow. Therefore, it has the effect of completely adhering the flow to the guide wall without reducing the air volume and deflecting the flow over a wide angle.

In FIGS. 3 to 5, 5 is a flow path for guiding the flow sent from a blower, etc., 6 is a rectangular nozzle having a throttle 7 around the entire circumference with respect to the axis 5a of the flow path, and 8 is a rectangular nozzle of the nozzle 6. This is a guide wall formed to surround the nozzle on the downstream side, and gradually expands from the exit of the nozzle 6 as a starting point. Moreover, this guide wall consists of four wall surfaces 8a, 8b, 8c, and 8d. On the upstream side of the nozzle 6,
A bias shield plate 9 is provided to block the bias flow generated by the aperture 7. This is located outside the nozzle near the exit of nozzle 6, and is located at the aperture 7.
It is in contact with Further, the bias shielding plate 9 is integrated with a rotating shaft 10 and is configured to move along the nozzle 6 in accordance with the rotation of the rotating shaft 10. This rotating shaft 10 is supported by a shaft support 11. Further, the rotating shaft 10 is configured to be able to slide in the shaft support 11 and move in the axial direction, and by this movement, as shown in FIG.
The gap d between the aperture 7 and the bias shielding plate 8 can be varied. As shown in FIG. 6, a guide groove 12 is cut in the rotating shaft 10, and a fixing ball 13 provided on the shaft support 11
It is designed to be positioned by.

右側に広角に偏向する。この時の偏向角度は案内
壁８ａの形状によつて任意に設定できる。 The operation of the above configuration will be explained using FIGS. 8 and 9. First, the direction in which the bias shielding plate 9 is viewed from the side as shown in FIG. 8 will be described. A part of the flow that enters in the direction of the axis 5a of the channel becomes a bias flow Fb by the throttle 7. Here, a bias flow Fb occurs on the left side of the figure, but no bias flow occurs on the right side due to the effect of the bias shielding plate. Therefore, the mainstream Fa is directed toward the guide wall 8a by the bias flow Fb from the left side, and the confluence F of Fa and Fb adheres to the guide wall 8a,
Wide angle deflection to the right. The deflection angle at this time can be arbitrarily set depending on the shape of the guide wall 8a.
第９図に示すように、バイアス遮蔽板９を正面

偏向する。従つてこのバイアス遮蔽板９を、回転
軸１０を回転することによつて移動すると、任意
の方向に流れを偏向させることが可能となる。 As shown in FIG. 9, when looking at the bias shielding plate 9 from the front, the bias flow Fb occurs both to the left and the right, so these two flows cancel each other out, and the combined flow F is directed to the front. Speech out. That is, the flow is deflected only in the direction where the bias shielding plate 9 exists. Therefore, by moving this bias shielding plate 9 by rotating the rotating shaft 10, it becomes possible to deflect the flow in any direction.
第１０図に示すように、回転軸１０を軸方向に
移動して間隙ｄを設けた場合は、この間隙を通る

ｄの大きさに比例して変化し、任意に設定でき
る。 As shown in FIG. 10, when the rotating shaft 10 is moved in the axial direction to provide a gap d, a bias flow Fd is generated passing through this gap. Due to this Fb, the adhesion of the flow F to the guide wall 8a is slightly weakened, and as shown in the figure, the blowing direction becomes intermediate between the frontal blowing and the maximum deflection. This blowing direction changes in proportion to the size of the gap d, and can be set arbitrarily.

向する。 Therefore, by rotating and moving the rotary shaft 10 in the axial direction, it becomes possible to blow out the flow in all directions three-dimensionally. Furthermore, at this time, the bias shielding plate does not come into contact with the main flow Fa, so it does not act as a resistance to the flow or disturb the flow, and the flow is deflected over a wide angle without reducing the air volume.

Reference numeral 15 is a guide wall, which is shaped like a wall. Reference numeral 16 denotes a bias shielding plate, which in this case has an arcuate shape. In operation, the flow adheres to the guide wall surface corresponding to the nozzle portion where the bias shield plate is located and is deflected, almost in the same way as in the first embodiment. In addition, in the case of this embodiment, the nozzle 14 is circular, the bias shielding plate 16 is arcuate, and the guide wall 15 is tapered, so the rotation interval of the bias shielding plate is not limited. , you can set the flow direction in any detail.
