Description

[Detailed description of the invention] [Technical field] This invention relates to an air conditioning outlet device installed in the ceiling of a building.

[Background technology]

FIG. 6 shows a side end surface of a conventional air outlet device installed in a ceiling. The box-shaped outlet main body 61 has a linear outlet 62 on its lower surface, and is connected to a duct 63 on its side. A movable blade 64 is provided in the linear outlet 62, and the rotation of the movable blade 64 causes the blowout air to
The air distribution pattern of a' and b' can be vertical as shown in FIG. 6, or horizontal as shown in FIG.

FIG. 8 shows an example in which the air outlet devices shown in FIG. 6 are installed on both sides of each lighting fixture 66 on a ceiling 67. 68 is the floor surface.

The reason why the blowing direction is made variable as described above is mainly due to the following reasons. That is, as shown in FIG. 8 by solid lines and broken lines showing the vertical blowout patterns during heating and cooling, respectively, the distance of the blown air is longer during cooling than during heating. Therefore, even if the air distribution pattern is good during heating, the blown air may reach close to the floor surface 68 during cooling, making the feet cold. A so-called draft phenomenon occurs.

Therefore, as shown by the chain line in the figure, horizontal airflow is used during cooling. However, if the installation distance between adjacent lighting fixtures 66 is narrow, if the horizontal blowout is used for cooling, wind collisions will occur as shown by the shaded area R in Fig. 8, and the colliding wind will descend, similar to the above. causes a draft phenomenon.

[Purpose of invention]

This idea is an air-conditioning outlet device that can change the blowing direction between vertical blowout and horizontal blowout, and also shortens the reach of the blowout air during horizontal blowout to avoid interference of the blowout air with nearby blowout devices. The purpose is to provide

[Disclosure of invention]

The air conditioning outlet device of this invention includes a box-shaped outlet body that has a linear outlet on the lower surface and is connected to a blower duct, and a box-shaped outlet body that is provided in the outlet body so as to be movable in the longitudinal direction of the linear outlet. a wind distribution control plate that changes the opening width of the linear outlet in the longitudinal direction; and a wind distribution control plate that is rotatable about a rotation axis along the longitudinal direction of the linear outlet It is equipped with movable vanes that regulate the air blowing direction.

According to the configuration of this invention, a movable blade that can rotate around the rotation axis along the longitudinal direction of the linear air outlet is provided, so by changing the angle of this movable blade, vertical or horizontal airflow can be achieved. You can In addition, we have installed a wind distribution control plate that changes the opening width of the linear outlet in the longitudinal direction, so that when the air blows out horizontally, the opening width of the linear outlet is widened by the air distribution control plate. can be expanded in the longitudinal direction, and the horizontal reach is shortened. Therefore, even if there is another outlet device nearby, interference of the outlet air when the cold air is blown out horizontally can be avoided, and comfortable cooling can be obtained.

Embodiment An embodiment of this invention will be described based on FIGS. 1 to 5. This air conditioning outlet device includes a box-shaped outlet body 3 that has a linear outlet 1 on the lower surface and is connected to a blower duct 2, and a linear outlet 1 that is movable in the longitudinal direction of the outlet body 3. A wind distribution control plate 4 is provided on the linear outlet 1 to change the opening width in the longitudinal direction of the linear outlet 1. It is provided with movable blades 5 which are movably provided and which regulate the direction of air blowing. The blower duct 2 is connected to a duct connection port 6 formed at the center of the front of the outlet body 3.

The air distribution control plates 4 are arranged near both ends inside the outlet main body 3, and are rotatably attached at each upper end by a hinge part 7, so that the lower end can be moved in the longitudinal direction of the linear outlet 1. ing. A stopper 9 is fixed to the inner surface of the outlet body 3, and prevents the air distribution control plate 4 from rotating inward from the vertical angle. The lower end surface of the air distribution control board 4 is an interlocking guide surface 4a having an arcuate curved surface.

The movable blade 5 is rotatably supported by the end plate of the outlet body 3 via a support shaft 10 at both ends. The upper end of the movable blade 5 is connected to the interlocking guide surface 4a of the air distribution control board 4.
As the air distribution control board 4 rotates,
The movable blade 5 rotates while being guided by the interlocking guide surface 4a. The movable blade 5 is biased in the direction of collapse by a torsion coil spring 12 (FIG. 3).

Reference numeral 13 denotes an operation means for the wind distribution control board 4, which includes a pair of bias springs 14 that tension and bias each wind distribution control board 4 toward the open side, and a cable material 1 such as a wire that connects both wind distribution control boards 4.
5, and a thermally expandable member 16 connected via 5.
The thermally expandable member 16 is made of a shape memory alloy formed into a coil spring shape. The thermally expandable member 16 is designed to be in an expanded state at low temperatures. Note that, as the operating means 13, a shape memory alloy in the form of a compression coil spring may be used that biases the air distribution control plate 4 toward the closing side. In that case, bias spring 14 is not necessary.

Operation According to this configuration, when hot air is blown out, the heat expandable member 1
6 is compressed, and the air distribution control board 4 is connected to the bypass spring 1.
4, it is pressed against the detent piece 9 to form a vertical angle (as shown by the solid line in FIG. 2). In addition, the movable blade 5 is connected to the interlocking guide surface 4 of the air distribution control board 4, as shown in FIG. 3A.
It is held at the upper end of a and forms a vertical angle. Therefore, as shown in FIGS. 4A and 4B, the blown air a is distributed vertically downward.

When cold air is blown out, the heat expandable member 16 is expanded by the cold air, and the air distribution control plate 4 is opened as shown by the chain line in FIG. 2 due to the restoring force of the bias spring 14. When the air distribution control plate 4 opens, the position of the interlocking guide surface 4a at the lower end thereof rises as shown in FIG. Therefore, as shown in FIG. 5A, the blowing wind b is in the horizontal direction. In addition, as the air distribution control plate 4 expands, the opening width of the linear air outlet 1 increases, and the pair of air distribution control plates 4 are inclined downwardly, so that the air flow b is increased as shown in FIG. 5B. It also spreads horizontally. Therefore,
The horizontal reach of the cold wind becomes shorter. Therefore, even if other air conditioning outlet devices are nearby, the problem of cold air blowing out in the horizontal direction colliding with and falling down can be solved.

In the above embodiment, the air distribution control plate 4 is rotatable, but the air distribution control plate 4 is not limited to a rotary type as long as it can change the opening width of the linear outlet 1. . In addition, the operation means 13 of the air distribution control board 4
may use a drive source such as a motor, or may be operated manually.

[Effect of idea]

The air conditioning outlet device of this invention is equipped with a movable blade that can rotate around the axis of rotation along the longitudinal direction of the linear outlet.By changing the angle of this movable blade, the air outlet can be set vertically or horizontally. It can be used as a speech bubble. In addition, we have installed a wind distribution control plate that changes the opening width of the linear air outlet in the longitudinal direction, so that when the air blows out horizontally, the air distribution control plate can widen the opening width of the linear air outlet. can be expanded in the longitudinal direction, and the horizontal reach is shortened. Therefore, even if there is another outlet device nearby, interference with the outlet air when blowing cold air horizontally can be avoided.
This has the effect of providing comfortable cooling.
