Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flow deflecting device that is provided at a blowout port of an air conditioner or the like and that deflects a flow from a blower source in an arbitrary direction to blow it out. .

PRIOR ART A conventional flow deflector is shown in FIG. In this, the flow discharged from the nozzle 1 is attached to the guide wall 3 by the deflecting plate 2 to deflect the flow. 4 is the nozzle 1 and the guide wall 3
It is a negative pressure region provided between and, whereby the deflection is further increased.

Problems to be Solved by the Invention In the above-mentioned conventional example, the deflection plate 2 can be rotated by the rotation of the knob 5 to deflect the flow of the nozzle in the circumferential direction, but in the front direction (upward in the figure). There is a problem that the flow cannot be directed and blown, the flow can be bent only in a certain direction, and the flow cannot be directed toward a person at an arbitrary position.

The present invention solves such a conventional problem, and makes it possible to blow in all directions in three dimensions and to send the flow to a person at any position.

Means for Solving the Problems In order to solve the above problems, the flow deflector of the present invention is
A nozzle provided at a downstream end of a flow passage through which a flow passes, having a throttle substantially perpendicular to the flow direction; a guide wall surrounding the inner diameter portion of the nozzle and gradually expanding toward the downstream side; An operating shaft that is provided in the passage and is movable back and forth in the flow direction of the flow passage and is rotatable, and the operating shaft that is provided on the downstream side of the nozzle penetrates the operating shaft to change the inclination angle with respect to the operating shaft, and the operating shaft is And a deflection member having a wing-like side surface provided with a fitting groove. The deflection member changes the inclination angle with respect to the operation shaft by moving and rotating the operation shaft in the front-rear direction, and causes the flow to flow. It is something that changes dimensionally.

Effect of the Invention With the above-described configuration, the inclination angle of the deflecting member is changed according to the movement of the operation shaft in the axial direction of the flow path, whereby the flow from the nozzle is controlled in its adhered state to the guide wall. It largely deflects from the front to the left and right, and in the entire circumferential direction.

Embodiments Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1 to FIG. 3, 6 is a flow path 7 for passing a flow.
Is a nozzle provided at the downstream end of the flow path 6 and having a throttle that is substantially perpendicular to the flow direction, and 8 is a guide wall that surrounds the inner diameter portion of the nozzle 7 and is formed in a gradually enlarged shape toward the downstream side. The cross section of the guide wall 8 perpendicular to the axial direction of the flow path is circular in the figure, but may be polygonal. An operation shaft 9 is movable and rotatable in the flow direction of the flow path 6, and is configured to be moved or rotated by the drive mechanism 9a. 10 is a bearing that guides the operation shaft. Reference numeral 11 denotes a deflecting member provided on the downstream side of the nozzle 7, having a wing-shaped cross section, and configured to rotate about a rotary shaft 12 provided downstream of the operation shaft 9. Denoted at 13 is an angle setting member having a substantially circular cross section, which is provided in the vicinity of the nozzle 7 so that the deflection member 11 abuts and the inclination angle α changes in accordance with the movement of the operation shaft 9 in the flow direction of the flow path. The member 11 is formed in a ring shape so as to be rotatable about the flow direction of the flow path of the member 11.
Reference numeral 14 is a spring that urges the inclination angle α in a direction to be reduced. Further, the deflecting member 11 is provided with a long groove 15 and is cut so that the deflecting member can be rotated within a range of an inclination angle α of about 90 ° as shown in FIG. Further, the width of the groove 15 is almost the same as that of the operation shaft so that there is no wasted space. The angle setting member 13 is fixed to the bearing support rod 10a of the bearing 10 by the angle setting support rod 13a. The bearing support rod 10a is fixed to the wall surface 6a of the flow path 6.

The operation of the above configuration will be described below with reference to FIGS. First, as shown in FIG. 5, when the inclination angle α of the deflecting member 11 is small, that is, when the operating shaft 9 moves to the downstream side, the flow blown out from the nozzle 7 does not interfere with the guide wall 8 and is almost in front ( It blows out upwards in the figure). In this case, since the operation shaft 9 is moved to the downstream side, the deflecting member 11 is also moved to the downstream side and the flow is less disturbed. (In the case of front blowing, it is better not to be affected by the deflecting member). Next, as shown in FIG. 6, when the operation shaft 9 is moved to the upstream side and the deflection member 11 is brought into contact with the angle setting member 13 to slightly incline the deflection member 11, the flow from the nozzle 7 Is tilted toward the guide wall 8 so that the flow and the guide wall interfere with each other and the flow is deflected to the right in the figure. Further, if the operation shaft is rotated around the axis of the flow path, it can be deflected to the left side in the drawing. Next, as shown in FIG. 7, when the operating shaft 9 is moved further upstream so that the inclination angle α is approximately 90 °, the flow from the nozzle is evenly adhered to the entire guide wall and is distributed over the entire circumference. Blow out.

As described above, by moving and rotating the operation shaft 9 in the axial direction of the flow path, the flow blown out from the nozzle can be deflected from the front in all the left and right directions and simultaneously in the entire circumferential direction. Further, since the deflecting member 11 has a wing-shaped cross section, the flow is less disturbed and the deflection is favorably performed.

Effects of the Invention As described above, according to the flow deflecting device of the present invention, the following effects are obtained.

By back and forth movement and rotation of one operating shaft, it becomes possible to direct the flow in all three-dimensional directions by combining the deflection of the flow in the direction of the deflection member and the deflection of the flow in the circumferential direction. As a result, the flow can be sent to a person at any position.
