Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an underfloor air conditioning outlet used for a free access floor.

[0002]

[Prior art]

 Conventionally, underfloor air conditioning has been performed using free access floors in office buildings and the like. FIG. 3 shows a schematic diagram of a conventional underfloor air conditioning. In FIG. 3, 1 is a free access floor, 11 is a floor support pillar, 12 is a conventional underfloor air conditioning outlet, and 13 is an outlet of the underfloor air conditioning outlet 12.

As shown in FIG. 3, the wind A blown from the air conditioner passes under the free access floor 1, passes through an underfloor air conditioning outlet 12 provided at the opening of the free access floor 1, The air is blown out from the blowing portion 13 onto the free access floor 1. As shown in FIG. 4, a conventional underfloor air conditioning outlet 12 has a free access floor 1 and a flat circular blowout portion 13 so that the air volume can be adjusted and the blowout pattern is a swirl flow B. It was increasing the effect.

Further, instead of using the underfloor air-conditioning outlet 12, as shown in FIG. 5, one free access floor 14 is provided with a large number of small holes 15 and blows out from the small holes 15. It was 5 (a) is a perspective view of the free access floor 14, and FIG. 5 (b) is a side view thereof.

[Problems to be solved by the device]

 However, the structure shown in FIG. 4 (FIG. 3) and FIG. 5 is effective in terms of stirring the air, but the blowing direction cannot be arbitrarily changed, and depending on the mounting position (blowing position), the discomfort caused by the air flow is strong. There was a problem of feeling. An object of this invention is to provide an underfloor air-conditioning outlet that can change the outlet direction arbitrarily and eliminate discomfort caused by airflow.

[0006]

[Means for Solving the Problems]

 The underfloor air-conditioning outlet of this invention is provided with an outlet main body projecting above the free access floor rotatably in the horizontal direction at the opening of the free access floor, and the outlet main body can change the vertical outlet direction. It is characterized by having a section.

[0007]

[Action]

 According to the configuration of the present invention, the outlet main body is rotatably rotatable in the horizontal direction, and the outlet main body is provided with the outlet capable of changing the vertical outlet direction, so that the outlet direction can be arbitrarily changed. , It is possible to eliminate the discomfort caused by the air flow.

【Example】

 An embodiment of this invention will be described with reference to the drawings. 1 (a) is a perspective view showing a state in which the underfloor air conditioning outlet of the first embodiment of the present invention is attached to a free access floor, and FIG. 1 (b) is a sectional view thereof. In FIG. 1, 1 is a free access floor provided with an opening 8, 2 is an outlet main body, and 3 is an outlet provided with a vane 4.

In this underfloor air conditioning outlet, a cylindrical outlet main body 2 is attached to an opening 8 of a free access floor 1 so as to be rotatable in the horizontal direction (arrow a direction). The blowout portion 3 of the blowout port body 2 is provided with a vane 4 movable as shown by an arrow b so that the blowout direction in the vertical direction can be adjusted. FIG. 2 (a) is a perspective view showing a state in which the underfloor air conditioning outlet of the second embodiment of the present invention is attached to a free access floor, and FIG. 2 (b) is a sectional view thereof. In FIG. 2, 1 is a free access floor provided with an opening 8 (see FIG. 1), 5 is an outlet main body, and 6 is an outlet provided with a vane 7.

In this underfloor air conditioning outlet, the outlet main body 5 has a dome shape, and other configurations are similar to those of the first embodiment. 1) and is rotatably mounted in the horizontal direction, and a vane 7 for adjusting the vertical blowing direction is provided at the blowing portion 6 of the blowing outlet body 5. According to the first and second embodiments, the outlet main bodies 2 and 5 are horizontally rotated and the vanes 4 and 7 provided in the outlets 3 and 6 adjust the vertical outlet direction. By doing so, the blowing direction can be arbitrarily changed, and the discomfort caused by the air flow can be eliminated.

It should be noted that one having a low overall height (outlet) in the first embodiment or one having a low overall height (outlet) such as the dome shape in the second embodiment is installed under a desk, Further, by installing a high total height (air outlet) in the first embodiment on the side of the desk or the side of the OA equipment, it becomes possible to perform air conditioning according to the load condition. Further, by making the size of the opening 8 of the free access floor 1 to which the outlet main bodies 2 and 5 are attached to be common, the outlet main bodies 2 and 5 can be easily replaced. In this case, by making the opening areas and the internal pressure loss of the blowout portions 3 and 6 of the blowout port main bodies 2 and 5 the same, the blowout air volume becomes constant regardless of which of the blowout port bodies 2 and 5 is attached, and the entire blowout air amount becomes constant. Air balance is maintained.

In the above embodiment, the outlet main bodies 2 and 5 are cylindrical and dome-shaped, but the shape is not limited to these.

[0013]

[Effect of device]

 The underfloor air conditioning outlet of this invention has an outlet main body rotatably in a horizontal direction, and an outlet part capable of changing the vertical outlet direction is provided in the outlet main body, so that the outlet direction can be arbitrarily changed. It is possible to eliminate the discomfort caused by the air flow.
