Abstract

PURPOSE:To make it possible to deflect air flow from the front face to the right or left or to any desired direction by changing the angle of inclination of a deflection member according to the movement of an operation shaft to the direction of a flow channel. CONSTITUTION:A flow of air is made to jet out by a nozzle 7 which is provided at the downstream end of a flow channel 6 which makes the air flow pass. A guide wall 8 is provided which surrounds the nozzle 7 and is formed to make a gradually enlarged form. It is made possible to move an operation shaft 9 provided in the flow channel 6 in the direction of the flow of the flow channel 6. Furthermore, a flow deflection member 11 provided on the downstream side of the nozzle 7 changes its angle alpha of inclination relative to the operation shaft 9 as the operation shaft 9 moves in the flow direction of the flow channel 6. That it, because the angle of inclination alpha of the flow deflection member changes by the movement of the operation shaft in the flow direction of the flow channel, it is made possible to deflect the flow to the right or left from the front face or to a desired direction.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a flow deflection device that is installed at the outlet of an air conditioner or the like and deflects the flow from an air source in an arbitrary direction. .

BACKGROUND OF THE INVENTION A conventional flow deflection device is shown in FIG. This is Noz/I/
The flow blown out from the guide wall 3 is caused to adhere to the guide wall 3 by the deflection plate 2, thereby deflecting the flow. Reference numeral 4 denotes a negative pressure area provided between the nozzle 1 and the guide wall 3, whereby the deflection is greatly increased.

Problems to be Solved by the Invention In the conventional example described above, it is possible to turn the deflection plate 2 by rotating the knob 5 and deflect the flow in the circumferential direction of the nozzle. The problem is that you can't direct the flow and blow it out.

The present invention solves these conventional problems and also makes it possible to blow air to the front.

Means for Solving the Problems In order to solve the above problems, the flow deflection device of the present invention comprises:
A nozzle that is provided at a downstream end of a flow path through which the flow passes and blows out the flow, and a guide wall that surrounds the nozzle and is formed in a shape that gradually expands toward the downstream side.

It has an operating shaft movable in the flow direction of the flow path, and a deflection member provided downstream of the nozzle.

The deflecting member has an inclination angle with respect to the operating shaft that changes in accordance with movement of the operating shaft in the axial direction of the flow path.

Function The present research has shown that with the above-described configuration, the inclination angle of the deflection member changes according to the movement of the operating shaft in the axial direction of the flow path, thereby controlling the layering state of the flow coming out of the nozzle onto the guide wall. This causes a large deflection from the front to the left and right.

Embodiments Below, one embodiment of the present invention will be described based on the accompanying drawings.

In FIGS. 1 to 3, 6 is a channel 7 through which the flow passes.
8 is a nozzle provided at the downstream end of the flow path 6 for blowing out the flow, and 8 is a guide wall formed to surround the nozzle 7 and gradually expand toward the downstream side. Although the cross section of the guide wall 8 perpendicular to the axial direction of the flow path is circular in the figure, it may be polygonal. 9
is an operating shaft that is movable and rotatable in the flow direction of the flow path 6, and is moved or rotated by a drive mechanism 9a. has been completed. 10 is a bearing that guides the operating shaft. Reference numeral 11 denotes a deflection member provided on the downstream side of the claw/L/7, which has an airfoil-shaped cross section and is configured to rotate around a rotating shaft 12 provided downstream of the operating shaft 9. Reference numeral 13 denotes an angle setting member having a substantially circular cross section and provided near the nozzle/L/7 so that the deflection member 11 comes into contact with the operating shaft 9 in accordance with movement in the flow direction of the flow path, and the inclination angle α changes. The reed is formed into a ring shape so that the deflection member 11 can rotate about the flow direction axis of the flow path. Reference numeral 14 denotes a spring that biases in a direction that reduces the inclination angle α.

Further, the deflection member 11 is provided with a long groove 15.
As shown in FIG. 4, the deflection member is cut so as to be rotatable within an inclination angle α of about 90°. Also, the width of the groove is almost the same as the operating shaft. Further, the angle setting member 13 is fixed to the bearing support rod 10a of the bearing 10 by an angle setting support rod 13a. and bearing support rod 1
0a is fixed to the wall surface 6a of the flow path 6.

The operation of the above configuration will be explained below using FIGS. 5 to 7. First, as shown in FIG. 5, when the inclination angle α of the deflection member 11 is small, that is, when the operating shaft 9 moves downstream, the flow blown from the nozzle /l'7 is directed toward the guide wall 8.
The air blows out almost to the front (upward in the figure) without interfering with the air.

In this case, since the operating shaft 9 is moved downstream, the deflection member 11 is also moved downstream, and the flow is less likely to be disturbed. (In the case of frontal blowing, it is better not to be affected by the deflection member.)
.

Next, as shown in FIG. 6, move the operating shaft 9 to the upstream side,
When the deflection member 11 is brought into contact with the angle setting member 13 and the deflection member 11 is slightly inclined, the flow coming out of the nozzle 7 is tilted toward the guide wall 8, and as a result, the flow and the guide wall interfere with each other. The flow is deflected to the right side of the diagram. Further, by rotating the operating shaft around the axis of the flow path, it can be deflected to the left side in the figure. Next, as shown in Figure 7, if the operating shaft 9 is moved further upstream and the inclination angle α is approximately 90°, the flow coming out of the nozzle will adhere evenly to the entire guide wall, and will spread over the entire circumference. Speech out.

As described above, by moving and rotating the operating shaft 9 in the flow direction of the flow path, it is possible to deflect the flow blown out from the nozzle in all directions from the front to the left and right, and simultaneously in the entire circumferential direction. . Furthermore, since the deflection member 11 has an airfoil-shaped cross section,
Deflection is performed well with little disturbance of the flow.

Effects of the Invention As described above, the flow deflection device of the present invention provides the following effects.

By moving the operating shaft in the axial direction of the flow path, the inclination angle of the flow deflection member changes, so that the flow can be deflected in any direction from the front to the right (or left).
