Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor blowout air conditioner, and more particularly to a floor blowout type air conditioner installed on a free access floor having a double floor structure.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional office room facility using a double-floor free-access floor, 1 is an office room, 2 is a lower floor, 3 is an upper floor board forming a free-access floor, 4 Is an access floor space formed between the upper floor plate 3 and the lower floor 2, 5 is a floor outlet provided in the upper floor plate 3, 6 is an exhaust chamber along the top of the office room 1, and 7 is this exhaust chamber 6 In order to divide the lower part of the ceiling plate, for example, a ceiling plate provided at a height of 2700 mm from the upper floor plate 3, 8 is a ceiling inlet formed in this ceiling plate 7, and 9a is an air conditioning partition in a living area where a person is located. ,
Reference numeral 9b is an air conditioning partition in a non-residential area where OA equipment, computers, etc. are located, and 10 is an air conditioning partition in the residential area 9a.
Laterally-directed air-conditioning air outlets formed on the side surfaces, 11 is a desk arranged adjacent to the air-conditioning partition 9a in the living area, 12 is an air conditioner, and 13 is the access floor space 4 described above.
And a connection duct for connecting the inside of the air-conditioning partition 9a in the living area.

In conventional office room equipment,
A large amount of wiring needs to be changed due to layout changes of equipment A, computers, etc. In order to make this change freely, a free access floor with a double floor structure is adopted, and warm air from the outlet of the air conditioner 12 or Cold air is supplied into the access floor space 4 between the upper floor plate 3 and the lower floor 2, and
It is blown into the office room 1 from the floor outlet 5 of the upper floor plate 3 and the connection duct 13 through the side outlets 10 of the air conditioning panel, and is provided on the ceiling plate 7 that constitutes the lower portion of the exhaust chamber 6. The ceiling suction port 8 enters the exhaust chamber 6 and returns to the suction port of the air conditioner 12.

Further, heat exhausted from office automation equipment, computers, etc. in the non-residential area is exhausted overhead from the side surface middle portion of the air conditioning partition 9b through the top opening of the air conditioning partition 9b.

[0005]

However, in the above-mentioned conventional office room equipment, however, the air-conditioning partition 9a and the access floor space 4 are connected to each other via the connection duct 13, and warm air or cold air is supplied from the side air outlet 10 of the air-conditioning partition 9a. Therefore, when the air-conditioning partition 9a is installed in the office room 1, the connection duct 13 obstructs the installation and cannot be freely installed.

Further, it has been extremely difficult to cope with this because it is necessary to largely move the air conditioning partition due to the layout change of the office automation equipment, the computer and the like.

The present invention eliminates the above-mentioned drawbacks.

[0008]

A floor blowout air conditioner according to the present invention has a hole formed in an upper floor plate at a desired position forming an access floor, a closing plate detachably fitted in the hole, and the closing plate. It is characterized by comprising a vent which is formed in the plate and an expandable connecting duct which connects between the air conditioning partitions.

The closing plate is displaceable within the hole of the upper floor plate.

The air conditioning partition is guided and moved by the closing plate.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

In the present invention, as shown in FIGS. 1 to 3, a circular hole 14 having a diameter of, for example, 500 to 600 mm is formed in any of the upper floor plates 3 forming the access floor, and a lattice is formed below the circular hole 14. A grating (lattice) 15 having a circular hole is fixed, a disk 16 is rotatably mounted on the grating 15, and a rectangular hole 17 is formed in the disk 16 at an eccentric position. An obstruction plate 18 having a width equal to, but having a width sufficiently smaller than that is slidably and detachably fitted in the rectangular hole 17 in the vertical direction (vertical direction in FIGS. 1 to 3). Put together.

Further, a ventilation hole 19 is formed in the closing plate 18, the lower end of an expandable and flexible connecting duct 20 is connected to the upper end of the ventilation hole 19, and the upper end is connected to the lower end of the air conditioning partition 9a. .

Further, the air conditioning partition 9a is movably mounted on the upper floor plate 3, and air conditioning partition guides 21 extending laterally (left and right in FIGS. 1 to 3) are provided on both upper surfaces of the closing plate 18. It is provided so that the lower end of the air conditioning partition 9a can be guided and moved in the lateral direction along this.

The blocking plate 1 in the rectangular hole 17
The part which is not closed by 8 is closed by the panel 22.

Since the floor blowout air conditioner of the present invention has the above-mentioned structure, the grid-like holes of the grating 15, the ventilation holes 19 of the closing plate 18 and the connecting duct 20 are provided between the air-conditioning partition 9a and the access floor space 4. Since the connection duct 20 is connected via the air-conditioning partition 9a and is not housed in the air-conditioning partition 9a and is not exposed to the outside, it does not impair the external appearance.
There is no fear of hindering the installation of a.

Further, in the present invention, since the closing plate 18 can be moved to some extent in the vertical direction in the rectangular hole 17 of the circular plate 16, the air conditioning partition guide 2 of the closing plate 18 is provided.
The position of the air conditioning partition 9a guided by 1 can be adjusted to some extent in the vertical direction, and the connection duct 2
Since 0 is a stretchable and flexible one,
The air-conditioning partition guide 21 allows the air-conditioning partition 9a to be largely moved in the lateral direction within the allowable range.

Furthermore, if the circular plate 16 is rotated in the circular hole 14 of the upper floor plate 3, the air conditioning partition 9 as shown in FIG.
The direction of a can be changed greatly. In this case, the upper floor plate 3 provided with the circular holes 14 is arranged at a different place.

In another embodiment of the present invention, two connecting ducts 20 are connected to the ventilation holes 19 of the closing plate 18, and one of them is connected to the air conditioning partition 9a in the living area as in the above embodiment. Then, connect the other to OA equipment, computer, etc. in the non-residential area.

[0020]

As described above, according to the floor blowout air conditioner of the present invention, it is not necessary to dispose the connecting duct outside the air conditioning partition, and there is a great advantage that a large change in the position of the air conditioning partition can be easily achieved. is there.
