Description of the Related Art In recent years, so-called system ceilings in which lighting lamps, fire detectors and the like and air conditioning air outlets are concentrated and arranged in a linear continuous manner have been frequently used from the viewpoint of interior beauty and quick construction. As an air outlet for air conditioning, a line-type diffuser having an elongated rectangular outlet formed on a lower surface capable of being constructed in harmony with them is widely used. As shown in FIG. 9, the wind direction switching in the conventional line-type diffuser has a length corresponding to the length of the long rectangular outlet,
A head portion 102 having a semicircular cross section having a pivotal support portion 100 and a plate-like blade portion 104 projecting perpendicularly to the same diameter from the center of the diameter portion of the circumference of the head portion 102 are integrally formed. The wind direction is switched by rotatably supporting the vane 106 thus rotated around the pivot 100. For example, in the case of blowing cold air in the summer as a horizontal airflow along the ceiling, the tip of the blade 104 is connected to one side wall 108 as shown in FIG.
And blows out from the gap between the other side wall and the head 102 as a horizontal airflow along the ceiling through the throttle portion of the air outlet, and blows warm air as a downward vertical airflow in winter. When the air is blown out, the tip of the blade 104 is directed directly downward as shown in (a), and the air is blown out vertically from the gap between both the head 102 and both side walls through the throttle portion of the air outlet.

は大きなコスト増を生じさせる。However, in the above-described air flow adjusting device for setting an air flow by rotating a ginkgo-shaped cross-section vane having a head portion and a wing portion integrated with each other, FIG.
As shown in (a), the area of the actual flow path changes significantly when the horizontal airflow is set and when the vertical airflow is set, so the pressure loss of the airflow fluctuates greatly, and a larger noise is generated when the horizontal airflow is set than when the vertical airflow is set. In addition to this, if the output of the blower fan is not adjusted, the amount of blown air fluctuates greatly, so that it is difficult to accurately control the air in the room each of which is carried by a plurality of diffusers connected to one entire duct system. Was. Further, since a large amount of air flows into the upper wedge-shaped space on the tip side of the closed blade portion 104 as shown in FIG. 9A and receives a rotational moment around the pivot portion such that the vane 104 is pushed open. In order to counter this, it is necessary to provide an adjusting and fixing mechanism for maintaining the vane at the set angle, which causes an increase in cost. In addition, as shown in FIG. 9 (a), when the blade tip is brought into contact with the side wall and one of the flow paths is fully closed, the vane is directly opened manually from the room side with a finger or a finger of a finger. It is difficult to return and rotate in the direction
To cope with this, it is necessary to separately provide a vane adjusting and fixing mechanism. Therefore, FIG.
As shown in (c), a certain amount of clearance must be left between the tip of the blade portion and the side wall so that operations such as rotation return adjustment can be performed with a fingertip or a nail, and the one-side flow path can be completely closed. As a result, air flows out from the gap, while air flowing out from the gap between the side wall and the head 102 and blown out from the blowout port flows along the ceiling due to the flowed out air as shown in the figure. However, there was a problem in that it did not peel off from the ceiling surface to form a stable horizontal airflow. Furthermore, since a wedge-shaped space that opens upward is formed above the tip of the blade portion 104,
A large amount of air is pushed into the gap between the tip of the blade portion and the side wall which is left slightly, and a thin and fast air flow is generated downstream of the gap, causing turbulence near the outlet, making it difficult to set a stable wind direction. There was a problem. In addition, the conventional vane, which is a long member with a complicated deformed cross section with a head and blades, first manufactures a special aluminum extrusion mold, and uses the deformed bar material as the long aluminum material. It is extruded and manufactured by additionally processing a pivot at both ends where the long material is cut, so that the manufacturing cost is high. Further, in the conventional vane including the head and the blade, at least the arc diameter of the head 100 on the vane side, the hanging length of the blade 102, the pivotal position of the rotation, the flow path width on the main body side, and the flow path lower end Must be aligned with each other, and the setting of the mounting position of the vane and the mounting structure are complicated.
In particular, for example, when the specification of the short side length of the line type diffuser is changed, when a corresponding vane is manufactured, a large increase in cost is caused.

And the other side is protruded into the flow path so as to face the other side with a gap. One of these opposed protruding sides serves as a sandwich holding plate, and a plate-like sandwich gap is formed between the sandwich holding plates. Both ends of the shielding body 16 are held in a state of being loosely fitted in the sandwiching gap. Therefore, the shield can slide in the short-side direction W of the air outlet 12 in a state where both ends are held therebetween. In the embodiment, the lower holding member 36 is formed of a rigid material, and the upper holding member 34 is formed of a leaf spring material. Thus, the sandwiching holding mechanism 32 holds the shielding body slidably with friction in the horizontal direction while restraining both ends of the shielding body in the vertical direction. The guide mechanism may slide and guide the shield 16 in the short direction of the air outlet 12. Therefore, the upper sandwiching holding member 34 is not provided, and only the both ends of the shield 16 are placed and received. May be constituted only by the receiving plate member.

Adjust the airflow to blow out. In other words, the shield always linearly slides in the short direction of the air outlet so as to always shield a certain area in the flow path in the air outlet frame and keep the total area of the actual air flow path constant. A selection flow path for selectively changing the actual flow flow path is set, and the blowing direction of the air flow is adjusted in cooperation with the outlet edge projecting frame portion. Change the actual air flow path only by sliding the outlet in the short direction, and
At this time, no change in the flow path area occurs, so that noise reduction can be achieved. Also, no matter what horizontal slide position the shield is set in the flow path, the pressure loss in the outlet frame is constant, and the load on the indoor side is constant and the output design of the blower is easily performed. . In addition, since the shield 16 is simply set at a required position while sliding, and is arranged so as to intersect with the flow direction of the air flow, the force received from the air flow is, for example, a force in a direction perpendicular to the air flow. The holding of the shield in the stationary position can be maintained, for example, even when the shield is loosely fitted from above and below, or held with some friction, or simply placed on the upper surface of the receiving member.

The occupant slides the shield 16 to the center of the flow channel width via the slide operation unit with a fingertip or the like to set it. As shown in FIG.
When 2 is formed, the airflow flowing down the opposed parallel flow path wall portion PS is equally distributed to the left and right by the upstream facing surface 26. Each of the divided flows that have passed through the selection flow paths p1 and p2 is bent toward the center side by the outlet edge projecting frame portion 20 and merges. The lateral velocities of the shunts are offset by the merging and are blown out as downward vertical airflows.

The shield 16 is slid so that the area of p2 and p2 are biased at an appropriate ratio. In the figure, an amount of air corresponding to the area passes through the narrower selection flow path p2.
Although the airflow that has passed through the wider selection flow path p1 has a substantially horizontal airflow component, it merges with the airflow that has passed through the selection flow path p2, is turned into an obliquely downward airflow, and is blown out.

え、簡単に戻す方向に再移動させることができる。By sliding the shield 16 in the short direction W of the outlet 12 in this manner, the direction of air flow is adjusted in cooperation with the outlet edge projecting frame 20. Even if the shield 16 is slid to set the wind direction variously as in (a), (b), and (c), the total area of the actual flow passage is constant regardless of the set position, and the wind direction of the air flow is changed. Regardless of the setting, the pressure loss of the airflow in the outlet frame is constant, the noise is reduced, and the air conditioning control can be easily performed. Further, even if the shield 16 is slid to a position where one side of the flow path is completely closed as shown in FIG. A force can be directly applied to the slide operation unit 28 provided, and the slide operation unit 28 can be easily moved again in the returning direction.

故障が少なく、製造コストを低廉にすることができる。As described above, according to the air flow control device for an air outlet of the present invention, an outlet frame having an elongated rectangular outlet on the lower surface, and the outlet of the air outlet in the outlet frame. A shield provided along the longitudinal direction and slid in the short direction of the outlet, a guide mechanism for guiding the sliding of the outlet in the short direction of the shield, and two opposing longitudinal edges of the outlet. And a shielding member that always projects a certain area in the flow path in the outlet frame so that the total area of the actual flow path is constant. It is characterized by forming a flow path and sliding the shield in the short direction of the air outlet so as to adjust the air flow direction in cooperation with the air outlet edge protruding frame portion, so that the air is blown into the room. Pressure loss in the outlet frame is constant even if the airflow direction is set variously It can facilitate accurate retention on the air conditioning design with reduced noise Te. In addition, a gap that should be closed when set to horizontal airflow and a narrow flow path when set to oblique airflow can realize an airflow adjustment structure that does not generate thin and fast airflow, so that the airflow blown into the room is intended It can be flowed in the direction. Also, changing the wind direction setting requires only sliding movement of the shield, so there is no need for an adjustment and fixing mechanism to lock the shield at the set position, simplifying the device structure, and changing the wind direction setting instantly and easily from the indoor side. It can be carried out. In addition, since the shield that slides and functions even with a simple shape, the manufacturing cost of parts is low, and the guide mechanism that slides and guides the shield may have a simple structure, and the device can be made thinner and lighter.
The number of failures is small, and the manufacturing cost can be reduced.

In addition, the pressure loss of the airflow in the outlet frame can be reliably kept constant to easily maintain the accuracy of the air conditioning design.

The air exceeding the pressure is forcibly pushed in, and a thin and fast air flow is generated downstream of the air flow, so that noise is not generated and a turbulent flow near the outlet does not disturb the blown air flow.
