Abstract

PURPOSE:To enable the execution of wide angled deviation without disturbing a flow, by a method wherein a nozzle, having a throttle throttled from a whole periphery toward the axis of a flow, is provided and a bias shield plate is situated up a line from the nozzle, and a bias flow shielding position and amount are varied. CONSTITUTION:A bias flow from other nozzle part, except a nozzle part where a bias flow is shielded, is exerted in a direction facing a nozzle part, where a bias flow produced by a throttle 7 of a nozzle 6 is shielded, and a flow F blown through the nozzle is deviated in the direction. A flow position shielded according to the movement of a bias shield plate 9 can be changed, and the direction of a flow can be changed arbitrarily. By changing a bias flow shielding amount, a deviating amount is controlled, and the flow can be blown in the direction of the middle part between a front and a maximum deviation direction. As a result, blowing in all directions is three-dimensionally practicable. Since the bias shielding plate is situated up a line from the nozzle, a flow is prevented from disturbance irrespective of flow resistance. Thus a flow is deviated at a wide angle without reducing an airflow.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention Industrial Field of Application The present invention is a device that is provided at an outlet of an air conditioner, etc., and is used to deflect and blow out a flow from an air source in an arbitrary direction. The present invention relates to a flow direction control device.

Conventional technology In an air conditioner that performs cooling and heating, it is desirable to control the airflow direction to downward blowing during heating and horizontal blowing during cooling in order to equalize the temperature distribution in the room being air conditioned. Further, due to the installation position of the air conditioner, etc., it is desirable to deflect the light over a wide angle in the left and right directions.

Conventional examples for achieving this purpose include those shown in FIGS. 111 and 12. -, 1a and 1b are guide walls (only two are shown in the figure, but there are many), 2 is a nozzle that blows out a flow, and a is a deflection plate rotated by a shaft 4.

Due to the flow guiding action of the deflection plate 4, the flow coming out of the nozzle adheres to the guide 91m, lb (one in FIG. 11) and is deflected. When the deflection plate 4 is rotated, the guide wall to which the flow adheres changes, and the blowing direction changes. Problems to be solved by the invention that deflects the flow by the above-described operation: This is because the deflection plate 4 is provided in the flow path, which creates resistance to the flow and also has a shape that disturbs the streamlines of the flow. This has had the problem of inevitably deteriorating the adhesion effect to the wall surface.

Means for Solving the Problems The present invention solves such conventional problems, and includes a nozzle provided at the outlet end of a flow path and having a restriction from the entire circumference with respect to the axis of the flow path, and a nozzle provided at the outlet end of the flow path, and a A bias shielding plate is provided on the side and blocks a part of the vial flow due to the constriction (flow toward the center of the flow path caused by the constriction), and the bias shielding plate has a variable position where it blocks the bias flow. , and the amount of flow obstruction is variable.

Function: With this configuration, the bias flow from other parts acts in the direction corresponding to the nozzle part where the bias flow generated by the nozzle throttle is blocked, and the flow blown out from the nozzle is deflected in that direction.

Furthermore, the position of the blocked flow changes according to the movement of the bias shielding plate, making it possible to arbitrarily change the direction of the flow.

Furthermore, by changing the amount of blocking the bias flow, the amount of deflection can be controlled, making it possible to blow air in an intermediate direction between the front direction and the maximum deflection direction. As a result, balloons can be generated in all directions in the a dimension. Further, in this case, since the bias shielding plate exists on the upstream side of the nozzle, it does not act as a resistance to the flow and does not disturb the flow. Therefore, the flow is completely attached to the guide wall without reducing the air volume,
It has the effect of deflecting the flow over a wide angle. .

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 5. In FIGS. 1 to 3, reference numeral 5 indicates a channel for guiding the flow sent from a blower or the like, and 6 indicates a rectangular nozzle having a throttle 7 around the entire circumference relative to the axis 5a of the channel. A bias shielding plate 9 is provided upstream of the nozzle 6 to block the bias flow generated by the aperture 7 . This is located near the exit of the nozzle 6 and is in contact with the aperture 7. Further, the bias shielding plate 9 is integrated with a rotating shaft 10 and is configured to move along the nozzle 6 in accordance with the rotation of the rotating shaft 10. This rotating shaft 10 has a shaft support 11
Supported by

The rotating shaft 10 is configured to be able to slide in the shaft support 11 and move in the axial direction, and by this movement, the gap d between the aperture 7 and the bias shielding plate 8 is reduced, as shown in FIG. It is made variable.

As shown in FIG. 4, the rotating shaft 10 has a guide groove 1.
2, and is positioned by a fixing ball 13 provided on the shaft support 11.

The operation of the above configuration will be explained using FIGS. 6 and 7. First, the direction in which the bias shielding plate 9 is viewed from the side as shown in FIG. 6 will be described. A part of the flow that enters in the direction of the axis 5a of the channel becomes a bias flow Fb due to the throttle 7. Here, a bias flow Fb occurs on the left side of the figure, but no bias flow occurs on the right side due to the effect of the bias shielding plate. Therefore, the mainstream Fa is deflected to the right by the bias flow Fb from the left, and Fa and F
The confluence F of b is deflected to the right.

As shown in FIG. 7, when the bias shielding plate 9 is viewed from the front, the bias flow Fb occurs both to the left and to the right, so these two flows cancel each other out, resulting in a combined flow Fb.
blows out in front. That is, the flow is deflected only in the direction where the bias shielding plate 9 exists. Therefore, by moving this bias shielding plate 9 by rotating the rotating shaft 10, it becomes possible to deflect the flow in any direction.

As shown in FIG. 8, when a gap d is provided by moving the rotating shaft 11 in the axial direction, a bias flow Fd passing through this gap
occurs. Due to this Fd, the deflection of the flow F is slightly weakened, and as shown in the figure, the blowing direction is intermediate between the frontal blowing and the maximum deflection.

This blowing direction changes in proportion to the size of the gap d, and can be set arbitrarily.

Therefore, by rotating the rotation shaft 11 and moving it in the axial direction, the flow can be blown out three-dimensionally in all directions. Further, at this time, since the bias blocking plate does not come into contact with the main stream F1, it does not create resistance to the flow or disturb the flow, and the flow is deflected over a wide angle without reducing the air volume.

Next, another embodiment of the present invention will be described using FIGS. 9 and 10. In the figure, 14 is a nozzle, which is formed in a circular shape. Reference numeral 16 denotes a bias shielding plate, which in this case has an arcuate shape. In operation, the flow is deflected in the direction corresponding to the nozzle portion where the bias shield plate is present, almost the same as in the first embodiment. In addition, in this embodiment, the nozzle 14 is circular and the bias shield plate 16
Since the bias shielding plate has an arc shape, the rotation interval of the bias shielding plate is not limited, and the blowing direction of the flow can be set arbitrarily finely.

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

(1) Since a deflection plate or the like is not inserted into the blowout flow, the air volume does not decrease, and since there are no objects in the flow, the flow is not disturbed, and a wide-angle deflection can be obtained.

(2) By rotating and moving the rotating shaft in the axial direction, it is possible to set the direction of the blowout flow in any three-dimensional direction.

(3) When applied to the air outlet of an air conditioner, the effect of (1) allows the air flow to be deflected vertically and horizontally without reducing the air volume, resulting in a great air conditioning effect.
