DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art FIG. 16 shows a conventional office room equipment using a double floor structure free access floor, wherein 1 is an office room, 2 is a lower floor, and 3 is a free access floor, for example, 500 mm × 500 mm. , A large number of square upper floor boards, 4 is an access floor space formed between the upper floor board 3 and the lower floor 2, 5 is a floor outlet provided at an arbitrary part of the upper floor board 3, and 6 is an office room 1. An exhaust chamber 7 along the top defines a lower part of this exhaust chamber 6, for example 2700 mm from the upper floor 3
, A ceiling inlet formed in the ceiling plate 7, an air-conditioning partition 9 a provided in a human living area, 9.
b is an air-conditioning partition provided in a non-living area where OA equipment, computers, etc. are located, 10 is a laterally-directed air-conditioned air side outlet formed on a side surface of the air-conditioning partition 9a in the living area, and 11 is a living area. Desk, 12 is an air conditioner, and 13 is the access floor space 4 described above.
And a connection duct connecting the inside of the air-conditioning partition 9a in the living area.

In conventional office room equipment, O
A lot of wiring changes are required along with the layout change of the A-devices and computers, and a free access floor with a double floor structure is adopted to make this change free. Is upper floor board 3 and lower floor 2
And 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 outlet 10 of the air-conditioning panel, and the exhaust chamber 6 From the ceiling suction port 8 provided in the ceiling plate 7 constituting the lower part of the air conditioner, and returns to the suction port of the air conditioner 12.

[0004] In a non-residential area, heat exhausted from OA equipment, computers, and the like is exhausted overhead from an intermediate portion of the side surface of the air conditioning partition 9b through an opening at the top of the air conditioning partition 9b.

However, in the above-mentioned conventional office room equipment, the air-conditioning partition 9a and the access floor space 4 are connected via the connection duct 13, so that warm air or cold air is blown 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 connecting duct 13 becomes a hindrance and cannot be installed freely.

[0006] In addition, it is necessary to move the air-conditioning partition largely according to the layout change of the OA equipment, the computer and the like, but it has been extremely difficult to cope with this.

[0007] For this purpose, Japanese Patent Application No. 5-91906 proposes an improved floor air conditioner.

In this floor blow air conditioner, FIGS.
Upper floor plate 3 forming an access floor as shown in FIG.
For example, a circular hole 14 having a diameter of 440 mm is formed in any one of the above, and a grating 15 having a grid-like hole is fixed below the circular hole 14.
6 is rotatably fitted, a rectangular hole 17 is formed in the circular plate 16 at an eccentric position, and a closing plate 18 is movably fitted in the rectangular hole 17, and a through hole formed in the closing plate 18 is formed. Stoma 1
The lower end of an extendable and flexible connecting duct 20 is connected to the upper end of the connecting duct 9, and the upper end of the connecting duct 20 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 so as to be movable along an air-conditioning partition guide 21 extending on both sides of the upper surface of the closing plate 18.

The closing plate 1 in the rectangular hole 17 is used.
Portions that are not closed by 8 are closed by panels 22.

In the floor air-conditioning system of the above-mentioned proposal, as shown in FIG. 19, between the air-conditioning partition 9a and the access floor space 4, a grid-like hole of the grating 15, a ventilation hole 19 of the closing plate 18 and a connection duct 20 are provided. The connection duct 20 is housed in the air-conditioning partition 9a and does not go outside, so that the appearance is not impaired and the installation of the air-conditioning partition 9a is not hindered.

Further, the closing plate 18 is formed in the rectangular hole 17 of the disc 16.
Air conditioner partition 9a
Can be adjusted to some extent.

Further, if the disk 16 is rotated in the circular hole 14 of the upper floor plate 3, the direction of the air conditioning partition 9a can be largely changed as shown in FIG.

[0014]

However, in the floor air-conditioning apparatus using the above-discussed disk 16, the air hole 1
The size of 9 is limited, and it is impossible to flow a large amount of air.

Further, even if the air-conditioning partition 9a is largely moved on the upper floor plate 3, the air-conditioning partition 9a is limited by the degree of extension of the connection duct 20, and cannot be moved largely.

Further, there is a disadvantage that the connection duct 20 cannot be used for guiding electric wires and the like.

The present invention has been made to eliminate the above disadvantages.
