のである。 The operation in the above configuration will be explained. The operation of the present invention is shown in FIGS. 4 to 7. In FIG. 4, the control means 4 faces the front, but in FIGS.
It rotates clockwise as the diagram progresses, and in Figure 7 it rotates 90 degrees.
The case is shown when rotated to be perpendicular to the inlet flow. At this time, since the control plates 4a and 4b are pushed inward by the guide hole 8, the width W of the control means 4 gradually becomes smaller. At the same time, the width of the overlap between the slits 5a and 5b provided in the control plates 4a and 4b increases, resulting in a gradual increase in the width of the slit at the center of the control means 4. In FIG. 7, the slit width is the maximum. Next, the state of flow will be explained. Flow entering from inlet 2 as shown in Figure 4
Fi is the flow F L0 on the left side of the control means 4 (not shown)
and the central flow F 0 and the flow to the right of control means 4 F L0
(not shown). First, the case where the control means 4 faces the front as shown in FIG. 4 will be explained. In this case, the central flow F 0 is divided into the left and right sides of the control means 4, so the overall flow is F
There are only two, R0 and F L0 . At this time, F R0 and F L0
Since is symmetrical, F R0 will be explained. F
R0 is divided into a flow F R1 along the control means 4 and a flow F R2 deflected inward at the constricted portion of the nozzle 3. The confluence of these two flows F R3 becomes a flow slightly inward. On the other hand, the flow F L0 on the left side of the control means 4 similarly becomes a flow F L3 directed slightly inward, and the confluence of F R3 and F L3 becomes a flow F directed toward the front and is blown out. Next, the case where the control means 4 is slightly rotated to the left as shown in FIG. 5 will be explained.
First, the flow F R0 on the right side of the control means 4 is divided into a front flow F R1 and an inward flow F R2 as before, and the combined flow F R3 becomes a slightly inward flow. On the other hand, a part of the central flow F 0 becomes a flow F S that passes through the slit created in the control means 4, but most of the flow flows along the control means 4.
Confluence F L3 of flows F L1 and F L2 on the left side of control means 4
The flow turns slightly inward as before, but by colliding with the control means 4, it merges with the central flow F 0 and becomes a flow F L3 ′ along the control means 4.
becomes. Since this F L3 ' faces toward the guide wall 10L, a Coanda effect occurs between the flow F L3 ' and the guide wall 10L, and the flow F L3 ' adheres to the guide wall 10L.
Also, since the flow on the right side F R3 is facing leftward (inward), F L3 and F R3 merge, and both reach the guide wall 10.
It adheres to and flows. Therefore, the confluence F will be deflected to the left and blown out. At this time, the deflection angle θ of the confluence F is deflected using the action of the fluid itself called the Coanda effect, so the inclination angle α of the control means 4 is
However, the angle θ is larger than that of the angle θ. Therefore, the result is that the airflow resistance does not increase much but is largely deflected. At this time, F S , which is a part of the central flow, flows out of the slit, but in this case, the amount is small and has almost no effect on the deflection. Next, a case where the control plate is tilted greatly as shown in FIG. 6 will be explained. First, the flow on the right side of the control means 4 becomes a flow F R3 directed slightly inward as before. Further, the central flow F 0 collides with the control means 4, and part of it becomes a flow F S flowing out from the slit of the control means 4, and the other part becomes a flow along the control means 4. In this case, the slit formed in the control means 4 is widened, resulting in a large flow of F S . On the other hand, the flow F on the left side of the control means 4
When L1 and F L2 merge, F L3 collides with the control means 4 as in the case of FIG. 5, merges with a part of F 0 and adheres to the guide wall 10L. Then, F R3 ′ is also attracted by F L3 ′ and tries to merge, but the flow from the slit F S
Since the merging is obstructed to some extent by the flow, the merging F cannot be completely deflected and blows out in the direction shown in FIG. At this time, as described above, the control means width W has become smaller and the flow blown out from the slit has increased, so the air flow resistance has hardly increased. Next, a case will be described in which the control means 4 is perpendicular to the inlet flow Fi, as shown in FIG. The central flow F 0 impinges on the control means 4 and is split into F L2 ' and F L2 '. Control means 4〓〓〓〓
The right-side flows F R1 ' and F R2 are given outward vectors by F R2 ', but since the inward vector is larger, F R3 becomes a slightly inward flow. Similarly, the flow for F L1 and F L2 is slightly inward. Therefore, the confluence F of the three flows F R3 , F L3 , and F S becomes a flow facing the front. In this case as well, the flow resistance is small as in the case of FIG.

結局この動作を繰り返すことによつて左右へスイ
ング動作を行なうことになる。 In order to perform the above operation, in the present invention, by rotating the control means 4 in the same direction, the deflection is initially made to the left in proportion to the rotation angle of the control means 4, but when a certain point is reached, the control means 4 is rotated in the same direction. It no longer deflects, and now the blowing flow from the slit F S
The deflection angle θ gradually decreases under the influence of , and when the inlet flow and the control means become perpendicular, the air blows back to the front. If you rotate it further, the deflection angle will gradually increase to the left due to the same effect as above, reaching a peak value at a certain angle, and then the deflection angle will become smaller as you return to the front. .
Eventually, by repeating this motion, a swing motion to the left and right will be performed.

いう効果も得られる。 That is, by simply rotating the motor 12 in the same direction, the control means 4 is rotated, and as a result, it is possible to perform a swing motion from side to side. Further, as the control means is tilted, the width W of the control means becomes smaller and the width of the slit becomes larger, so that the swing operation can be performed with almost no change in air flow resistance.

グを行なわせることができる。 Next, an embodiment of the present invention will be described with reference to FIG. In the figure, only one side 10R of the guide wall 10 is configured to have a gradually enlarged shape. Therefore, when the control means 4 is rotated, it is possible to perform a one-sided swing of only the right half.

ため次の様な効果を有する。 As is clear from the above description, the flow direction control device of the present invention has a control means that rotates around an axis and a guide wall that has a gradually expanding shape, and the control means rotates and enters the inlet. The width of the control means is configured to become smaller as it approaches a state perpendicular to the streamline direction of the flow, and a slit is provided in the control plate, so that the control means rotates so that the width of the control means becomes smaller as it approaches a state perpendicular to the streamline direction of the flow.
