Description

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

Conventional configurations and their problems Conventionally, there are many areas where the air conditioning flow does not reach depending on the installation location and conditions of the air conditioner, so the flow can be deflected over a wide angle without reducing the air flow rate of the air conditioner. There is a growing need for directional control devices and a desire for simple means for deflecting the flow.

Hereinafter, a flow direction control device devised prior to the present invention will be described 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 toward the outlet section 3. The blades 5 provided on each of the plurality of shafts 4 are rotatable about the shaft 4. A blade 5 rotatably provided on the shaft 4 in one of the rows of a plurality of shafts 4 arranged so as to have a gradually expanding shape.
are each rotated by a predetermined angle so that adjacent blades 5 are connected to form a guide wall 6. In addition, the width of the blades 5 may be set to be equal to or larger than the distance between the shafts so that the guide wall 6 can be formed so as not to cause a gap between the blades, but in order to make the guide wall 6 smooth, The width of the blade 5 is made equal.

In the above configuration, in the state of the blades as shown in FIG. They interfere with each other and adhere and flow due to the Coanda effect. Of course, since the blades 5 are rotatable around the shaft 4, the blades can also be oriented so that the left and right sides are switched as described above, and can therefore be deflected to the left with respect to the flow direction. As a result, the flow is deflected at a wide angle in the direction of extension of the formed guide wall.

However, when the flow blown out from the outlet part 3 is deflected to the right side with respect to the flow direction along the flow path 1, and when it is made to proceed straight, the blades 5 forming the guide wall 6 are rotated at different angles. The flow direction must be parallel to the flow direction along the flow path 1. Also, the vanes 5 on the side facing the flow along the flow path 1 must likewise be rotated through different angles so as to be parallel to the flow along said flow path 1. Therefore, as a future challenge, when the flow blown out from the outlet section 3 is made to go straight or deflected to the left or right, it is possible to freely change the outlet section with a simple operation by rotating the blades 5 at different angles. 3
It is necessary to deflect the flow in the longitudinal direction.

Purpose of the Invention The present invention has been made in view of the above-mentioned problems, and it is possible to rotate a plurality of blades by a predetermined angle at once with a simple operation, and deflect the direction of the flow in the longitudinal direction of the outlet over a wide angle. The present invention provides a flow direction control device that can control the flow direction.

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 directions provided to cross the flow flowing along the flow path. a shaft, a blade that is provided on each of the plurality of shafts and rotates with the rotation of the shafts, and a rotation angle control device that rotates the shaft fixing the blade by a different predetermined angle, The shafts are arranged in pairs so as to gradually expand from the inlet to the outlet of the flow passage, and the blades provided on the plurality of shafts arranged in the pairs are rotated as necessary. Rotated by a predetermined angle via an angle control device, one of the blades arranged in the pair can form a guide wall to which the flow adheres due to the Coanda effect, and the other blade contributes to the flow attached to the guide wall. The structure is such that it faces in the direction of

According to this configuration, the rotation angle control device rotates the plurality of axes by different predetermined angles.
The rotation angle of the blades provided on each of the plurality of shafts can be gradually changed from a location close to the outlet section to a location close to the inlet section.

DESCRIPTION OF EMBODIMENTS A flow direction control device according to an embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 4, 5 and 6, 7 is a flow passage, 8 is an inlet, and 9 is an outlet. 11
are vanes rotating with a plurality of shafts 10 provided to cross the flow flowing along the flow path 7. The plurality of shafts 10 are arranged in pairs in a shape that gradually expands from the inlet portion 8 to the outlet portion 9, and each shaft of one of the shafts arranged in the gradually expanded shape is rotated by a predetermined angle, and The matched blades are brought into contact with each other to form a guide wall 12. Further, gears 13 and 14, which are rotating members, are provided adjacent to each other on the peripheral surfaces of the distal ends of the plurality of shafts 10, and the diameters of the gears 13 and 14 increase as they approach the outlet portion 9. Furthermore, motors 15 and 16 necessary for rotating the gears are provided on the upper left and right sides of the flow passage 7, and the motors
The annular belts 17 and 18 that transmit the rotation of the motors 15 and 16 to the gears 13 and 14 are connected to the motors 15 and 16 and the gear 1.
They are installed between 3 and 14 respectively. The above-mentioned gears 13, 14, motors 15, 16, and belt 1
7 and 18 constitute the rotation angle control device.

Next, a case will be described in which the flow blown out from the outlet portion 9 of the flow passage 7 is deflected from the straight direction to the right side with respect to the flow along the flow passage 7. In FIG. 6, the state of the blades that cause the flow blown out from the outlet portion 9 to travel straight is shown by broken lines. In other words, to make the flow go straight, the flow path 7
All the blades are parallel to the flow along. In order to deflect the flow from the straight direction to the right side with respect to the flow along the flow passage 7, a guide wall 12 is installed on the right side with respect to the flow along the flow passage 7.
At the same time, the blades on the left side should be oriented to the right side with respect to the flow along the flow path 7 so as to attach to the guide wall 12 and contribute to the flow flowing along the flow path 7. Must be.
However, since the shape of the guide wall 12 is gradually enlarged, the blades move from a direction close to parallel to the flow along the flow path to a direction close to perpendicular to the flow as they approach the outlet part 9. The angle at which the passageway 7 is rotated clockwise (hereinafter referred to as clockwise) when viewed from the top must be increased as the outlet portion 9 is approached. In other words, gear 13,
The diameter of the motor 14 increases as it approaches the outlet 9, and the rotation of the motors 15, 16 is controlled by the belts 17, 1.
8, the gears 13 and 14 are rotated in conjunction with each other, and the shaft closer to the outlet section is configured to have a larger rotation. In addition, the rotation of the motor 16 is controlled by the belt 18 so that the left blade faces the right side (rotates clockwise) with respect to the flow along the flow path 7.
and rotates the gear 14 in conjunction with the transmission.
In this case, the blades closer to the outlet 9 have a larger rotation angle, so the blades 11 are not all parallel.
Since the rotation angles of the blades 11 are oriented in substantially the same direction, there is almost no problem even if the flow is deflected.
On the other hand, if the motors 15 and 16 are rotated counterclockwise, a guide wall is formed on the left side for the flow along the flow path 7, and the right wing 11 is attached to the guide wall and contributes to the flow. can be directed,
The flow can be deflected to the left.

As described above, according to this embodiment, by providing a gear with a larger diameter as it approaches the exit portion, and further applying clockwise or counterclockwise rotation to the motor via a belt to the gear, a plurality of blades 11 can be rotated by a predetermined angle at a time, and a guide wall with a gradually expanding shape can be formed on either the left or right side with respect to the flow along the flow path, and on the other hand, it can be attached to the guide wall in a direction that contributes to the flowing flow. By rotating the blades 11, the flow can be freely deflected over a wide angle in the longitudinal direction of the outlet portion 9 by a simple operation.

Hereinafter, a flow direction control device according to another embodiment of the present invention will be described with reference to FIG. In FIG. 7, the rotation angle control device is somewhat different from the flow direction control device of the embodiment of the present invention described above (see FIGS. 4 to 6). That is, the outlet portion 9 is located at the tip of a plurality of shafts 10 arranged in pairs so as to gradually expand from the inlet portion 8 to the outlet portion 9.
There are provided cylinders 19, 20 with smooth outer peripheral surfaces, which are rotating members whose diameter decreases as the diameter approaches the cylinders 19, 20, motors 15, 16, and belt 1.
The only difference is that a rotation angle control device composed of 7 and 18 is used, and the other configurations are the same.
In operation, the motors 15 and 16 are rotated, and the belts 1 are placed around the outer peripheries of the cylinders 19 and 20, respectively.
By moving the shafts 7 and 18, the shaft 10 provided with a cylinder with a smaller diameter rotates more, so the blades 11 can be rotated more as they get closer to the outlet 9, and the guide wall 12 can be formed, increasing the effect. Even on the surface, the flow can be freely deflected over a wide angle in the longitudinal direction of the outlet portion 9 with a simple operation.

In the embodiments described above, the annular belts 17, 18 are moved using the motors 15, 16, but the driving source for moving the belts 17, 18 may be a manual lever or the like. In addition, in the embodiment, the gears 13, 14 or the cylinder 1
A circular belt 1 is used to move the parts 9 and 20 in conjunction with each other.
7 and 18 were used, but it is also possible to use meshing gears, a belt with ends, or drive each shaft with an independent motor.

Effects of the Invention As described above, the present invention includes a rotation angle control device that rotates a plurality of axes by different predetermined angles, so that a plurality of blades can be rotated in the same direction by a simple operation of the rotation angle control device. Furthermore, since each blade can be rotated by a predetermined angle, it is possible to easily form a guide wall with a gradually expanding shape, and the blades can also be rotated so as to attach the guide wall and contribute to the flowing flow. The flow of the flow direction control device can be very easily and freely deflected over a wide angle in the longitudinal direction of the outlet, and the effect is great.
