Furthermore, when a flow only along one of the guide walls 12 is formed, another flow can contribute to the flow along the guide wall 12 is formed on the other side. As a result, the flow can be easily deflected over a wide angle range in the longitudinal direction of the outlet 9.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a flow direction control device capable of deflecting a flow blown out from an air conditioner or the like in the longitudinal direction of all outlets.

Conventional configuration and its problems Conventionally, there are many areas where the air conditioning air does not reach depending on the installation position and conditions of the air conditioner, so it is possible to deflect the air flow over a wide angle in the longitudinal direction of the air outlet, and it is easy to operate. Therefore, there has been a desire for something that can deflect IJ.

Hereinafter, a flow direction control device devised prior to the present invention will be explained with reference to FIGS. 1, 2, and 3.

In FIGS. 1, 2, and 3, 1 is a flow passage, 2 is an inlet, and 3 is an outlet. A plurality of shafts 4 are provided so as to cross the flow flowing along the flow path 1, and are arranged in pairs so as to gradually expand from the inlet section 2 to the outlet section 3. The blades 6 provided on each of the plurality of shafts 4 are rotatable around the shaft 4 . A plurality of shafts 4 arranged in pairs so as to gradually expand in shape.
On the other hand, the guide wall 6 can be formed by rotating each of the blades 5 rotatably provided on the shaft 4 by a predetermined angle so that adjacent blades 6 are connected.

In addition, the width of the blade 60 is such that the guide wall 6 can be formed.
In order to avoid gaps between the blades 5, the distance between the shafts may be set to -, but in order to make the guide wall 6 smooth, the distance between the shafts and the width of the blades 6 are made equal.

In the above configuration, as shown in FIG.
The right wing 6 is connected to the guide wall 6 for the flow along the
The flow is deflected to the right with respect to the direction of flow by the left wing 6'ff: the group of flow vanes 5, and the flow deflected to the right interferes with the guide wall 6. Due to the Coanda effect, the water adheres to the guide wall 6 and flows. On the other hand, since the blades 5 are rotatable around the shaft 4, the left blades 5 are connected to form a complete guide wall for the flow along the flow path 1, and the right blades 5fc are used for the flow along the flow path 1. If it is rotated to the left, the flow blown out can be deflected to the left. Furthermore, by rotating the blades 5 so as to be parallel to the flow along the flow path 1, the flow blown out can be made to travel straight. As described above, this flow direction control device is capable of deflecting the flow blown out in the extending direction of the guide wall that can be formed by the vanes 5, and can also cause the flow to proceed in a straight line.

However, the flow blown out from the outlet part 3 is
In order to change the state from being deflected to the right with respect to the flow direction along the flow path 1 to a state in which the flow is deflected straight, the vanes 5 forming the guide wall 6 are rotated at different angles so that the flow direction along the flow path 1 is It must be parallel to the flow. Of course, if the flow to be blown out goes straight and is deflected to the left and right, the blades 5 must be rotated at different angles. Therefore, the future challenge will be to move and rotate the blades 5. It is possible to freely form a guide wall by using a simple mechanism and operation, and to deflect the blowing direction more freely.

Purpose of the Invention The present invention has been made in view of the above-mentioned problems, and provides a mechanism that allows deflection over a wide angle in the longitudinal direction of the air outlet, and that allows the flow to be freely blown out by rotating a plurality of blades with a simple operation. also provides a simple flow direction control device.

Structure of the Invention To achieve this object, the flow direction control device of the present invention includes a flow path having an inlet portion and an outlet portion, and a plurality of flow direction control devices provided to cross the flow flowing along the flow path. a shaft, a blade that rotates together with the plurality of shafts, and an interlocking device that rotates the plurality of shafts in conjunction with each other in the same direction, and the plurality of shafts gradually expand in shape from the inlet to the outlet. The shafts are arranged in such a manner that they gradually face outward as they approach the exit portion, and by operating the interlocking device, the plurality of shafts are interlocked and rotated by a predetermined angle, thereby gradually expanding the shape. The blades provided on one nqh of a plurality of shafts arranged in pairs so that The structure is such that it faces in a direction that contributes to the flow.

According to the above configuration, when the interlocking device is activated, all the blades are rotated in the same direction and at the same angle, and as they approach the outlet, one of the blades, which is gradually turned outward, forms the entire guide wall. , the flow deflected by the other vane interferes with the flow that adheres to the guide wall and flows in a direction in which the other vane adheres to the guide wall and contributes to the flow,
The flow blown out from the outlet can be deflected on the extension of the guide wall.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 4, 6 and 6, 7 is a flow path having an inlet 8 and an outlet 9. In FIGS. 1° across the flow flowing along said flow path 7. Each of the plurality of shafts 10 is provided with a blade 11, and as the shaft 10 rotates, the blade 11 also rotates, and the guide wall 12 can be formed by rotating the shaft 10 by a predetermined angle. A ring-shaped belt 13, which is an interlocking device, is placed on the circumference of the tip of one of the plurality of shafts 1Q, and a ring-shaped belt 13, which is an interlocking device, is placed on the circumference of the tip of the other shaft. A belt 14 is applied, and the belts 13 and 14 are moved by motors 15 and 16, respectively. As shown in FIG. 6, when the flow is made to proceed completely straight (hereinafter referred to as the initial state), the blades 17 and 18 are rotated so as to gradually face outward as they are closer to the outlet portion 9. This allows either vane 17 or vane 18 to form a guide wall when rotated in the same direction at a predetermined angle.

According to the above configuration, if the motors 15 and 16 are rotated by the same angle in the clockwise direction (hereinafter referred to as clockwise) when viewed from the upper part of the flow passage 7 from the initial state, the respective belts will be rotated by the same distance. 13°14 moves, bell) 13.1
The shafts 10 on which the numbers 4 are respectively attached are interlocked and rotated in the same two directions and at the same angle. Therefore, the specified angle from the initial state.

The blades 17 in the initial state are rotated clockwise by a predetermined angle two times to form the guide wall 12, and the blades 18 in the initial state follow the flow as they approach the inlet. It is rotated little by little to the right with respect to the flow along the passage 7, and becomes in the state of a vane 11. The vanes 11 facing to the right with respect to the flow along the flow passage 7 deflect the flow to the right with respect to the flow along the flow passage 7, thereby contributing to the flow that adheres to the guide wall 12 due to the Coanda effect. Therefore, the flow blown out from the outlet section 9 is largely deflected to the right.

Next, the motors 15 and 16 are each rotated by a predetermined angle counterclockwise to return the blades to their initial state, and the blades 17.
18 is rotated so as to gradually face outward as it approaches the outlet portion 9, but the flow is large enough to proceed straight and there is no problem in actual use.

Furthermore, if the motors 15 and 16i are each rotated by a predetermined angle in the counterclockwise direction, the blades 18 in the initial state form a guide wall, and the blades 17 in the initial state are rotated to the left with respect to the flow along the flow path 7. This causes the flow to be largely deflected to the left.

In the above example, r, 扛 give an initial state in advance when the flow is in a straight line state, and from that state, the belt 13.14 and motor 15.16 gradually expand the shape. - The plurality of shafts 10 mentioned above are rotated in conjunction with each other at the same angle in the same direction, - The blades 11 provided on one of the plurality of shafts 10 mentioned above form a guide wall, and the blades 11 of the other side By attaching it to the guide wall and directing it in a direction where it can contribute to the flowing flow, it is possible to deflect the flow blown out in the longitudinal direction of the outlet over a wide angle, and the rotation of the motors 15 and 16 can be controlled. The flow t'L blown out can be freely deflected over a wide angle using a chisel, and since there is no need for a rotation angle control device such as a gear to rotate each blade by a predetermined angle, it is mechanically very simple. 10. The effect is great from the standpoint of cost and durability.

In addition, in the embodiments described above, the annular bell t4
- A plurality of shafts arranged in a gradually expanding shape were rotated in conjunction with each other in the same direction. Even if you use an interlocking device such as a belt, it will not break.

Effects of the Invention As described above, the present invention provides the blade with a so-called initial state in which the blade is gradually oriented outward as it approaches the exit portion, and then controls the blade to gradually expand from that initial state by means of an annular belt. If multiple shafts arranged in It is possible to deflect the flow that is blown out at a wide angle in the longitudinal direction of the outlet in a direction that contributes to the attached flow, and therefore, the flow that is blown out at will can be deflected simply by fully operating the interlocking device. It can be deflected, and since there is no need for a rotation angle control device such as a gear to rotate each blade by a predetermined angle, it is possible to realize a flow direction control device with a simple mechanism, and it is cost-effective and durable. From this point of view, the effect is significant.
