【Example】

 An embodiment of the present invention will be described with reference to the drawings. In the embodiment described below, an example in which the air supply port 1a is provided on the ceiling 2 will be described, but it is of course applicable to the case where the air supply port 1a is provided on the side wall. First, the structure will be described. As shown in FIGS. 1 and 2, a rectangular air supply duct 1 has an air supply port 1a opening to a ceiling 2. A cylindrical PVC pipe 3 is arranged in the center of the air supply port 1a, and eight perforated plates 4 are attached so as to surround the PVC pipe 3.

As shown in FIGS. 1 and 3, each of the porous plates 4 has a main body 4a formed in a rectangular shape, and an attachment portion 4b is provided on an end side thereof, and a large number of the main body 4a are provided. The small hole 4c is opened. It is detachably supported on the inner peripheral surface of the air supply duct 1 and the outer peripheral surface of the PVC pipe 3 via the mounting portion 4b and is detachably supported by a chain (not shown) to prevent falling. It is hooked on the air duct 1.

The wind direction adjusting plates 5 are attached to the inner surfaces of the six porous plates 4 out of the eight porous plates 4 (the positions of the left and right three plates shown by A in FIG. 1). As shown in FIGS. 4 to 6, each wind direction adjusting plate 5 is configured by fixing a plurality of blades 5b to a rectangular frame 5a having the same shape as the shape of the multi-hole plate 4 to be attached. . In the figure, the wind direction adjusting plate 5 provided with five blades 5b is shown as an example.

The plurality of blades 5b are fixed at a predetermined angle with respect to the frame 5a, for example, by 40 degrees. Further, a magnet sheet 7 which is a magnet constituting a mounting means is fixed to the frame body 5a of the wind direction adjusting plate 5, and the magnet sheet 7 is magnetically adhered to the inner surface of the porous plate 4, whereby the wind direction adjusting plate is formed. 5 are detachably fixed to the inner surface of the corresponding perforated plate 4.

Since the porous plate 4 is generally made of a magnetic material such as an iron plate, it can be magnetized. When the porous plate 4 is made of a non-magnetic material such as reinforced plastic, the magnetic material is fixed in advance at the position where the magnet sheet 7 contacts. The wind direction adjusting plate 5 may be made of reinforced plastic or the like to reduce its weight. Further, the magnet sheet 7 which is the attaching means may be fixed to the porous plate 4 side.

In the blowout port having the above-described structure, when the wind direction adjusting plate 5 is not attached to the perforated plate 4, the conditioned air sent along the air supply duct 1 receives the conditioned air. It collides with the perforated plate 4 with an air flow perpendicular to the plane of 1a, and blows out into the room as a gentle air flow downward from the innumerable small holes 4c formed in the perforated plate 4. In addition, when the room is partitioned by partitions, such as in response to tenant construction, it is necessary to change the blowing direction to optimize the indoor air flow.

In this case, the corresponding perforated plate 4 is once removed from the lower part, and the wind direction adjusting plate 5 is magnetically attached to the inner surface of the perforated plate 4 as described above, and the perforated plate 4 is again attached.

At the punching type outlet with the wind direction adjusting plate 5, the conditioned air sent along the air supply duct 1 collides with the wing plate 5b of the air direction adjusting plate 5, and the direction of the air flow is wing plate. 5b is changed to a direction corresponding to the inclination, and then the air flow is changed to collide with the inner surface of the perforated plate 4 and blow out into the chamber from the small holes 4c along the changed direction. By thus providing the wind direction adjusting plate 5, the wind direction is adjusted.

The inclination and the like of the blade 5b is determined according to the changing blowing direction. Further, depending on the desired wind direction adjustment, the inclination of each blade 5b may be different. Further, in the above-described embodiment, the air supply port 1a is divided into a plurality of compartments, and the separate air flow direction adjusting plate 5 is attached to each compartment, so that the blowing direction can be set in a plurality of directions, and it is possible to make a fine adjustment. The wind direction can be adjusted, and the optimal air flow distribution can be created in the room.

In the wind direction adjusting plate 5 of the above-mentioned embodiment, the blade 5b is described as a fixed type, but even if it is set as a variable type and the blowing direction can be adjusted with one wind direction adjusting plate 5. Good. The variable wing plate 5b includes a shaft rotatably supported by the frame body 5a, a wing plate body fixed to the shaft, and a stopper for restraining the rotation of the shaft. Good.

In the case of the fixed type, when finely adjusting the wind direction, it is necessary to prepare the wind direction adjusting plate 5 having a plurality of inclinations, but in the case of the variable type, one type This can be done with the wind direction adjustment plate. Also, in the case of the variable type, it is advantageous for storage by tilting the slat main body when storing it in a warehouse or the like. Further, in the above-described embodiment, the magnet sheet 7 is used as the attaching means, but for example, a hook is projected from the air flow direction adjusting plate 5 toward the perforated plate 4 to form the first hook portion, and the perforated plate 4 is also used. The wind direction adjusting plate 5 may be fixed to the perforated plate 4 by hooking the hook on the small hole 4c using the small hole 4c as the second hooking portion.

The second hooking portion is not limited to the small hole 4c, and a ring capable of hooking the hook may be provided on the inner surface of the porous plate 4 or the inner surface of the air supply duct 1 to serve as the second hooking portion.
