[0007]

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a system floor, which is laid at a predetermined height on a floor slab 2 of a room in which OA equipment and the like are provided by support legs 3 and the like. A space S is formed between the floor slab 2 and the system floor 1, and cables C such as power cables for OA equipment and telephone lines or communication cables are freely routed.

Reference numeral U denotes a floor air-conditioning unit which is set at an arbitrary floor panel 1a of the system floor 1 so as to blow air in the space S from the floor. In the present embodiment, air in the space S is simply blown out for the purpose of preventing heat generated from the OA equipment from staying in the room.
When ventilation or cooling / heating is required, outside air is introduced into the space S, or a heat source device for cooling / heating is connected to the space S.

As shown in FIG. 2, the floor discharge air conditioning unit U mainly includes a panel member 4, a blower 5, a duct portion 6, and a discharge port member 7.

The panel member 4 is made of, for example, a fiber-reinforced cement floor panel, and uses a low-cost one that does not produce a squeaky sound. The size of the panel member 4 is, for example, a widely used 500 × 500 mm module having the same size as the floor panel 1 a of the system floor 1, and is moved to a free position on the system floor 1. Can be set at an appropriate position by replacing the floor panel 1a.

The blower 5 comprises a casing 5a, rotating blades 5b, an electric motor M, etc.
Is designed to be as thin as, for example, 103.6 mm.
The rotating blades 5a are not limited to the plate fan as shown in the figure, but may be any of conventionally known centrifugal or axial flow fans such as a sirocco type, a turbo fan, a silent fan, and an axial flow fan. Fans are preferred.

The duct 6 is continuously connected to the discharge portion of the casing 5a, and has two outlets 6a on the upper side in contact with the panel member 4. A circular hole 4a is formed in the panel member 4 at the position of the outlet 6a.

A disc-shaped outlet member 7 is rotatably fitted in the circular hole 4a. As shown in FIG. 3, the blowout member 7 has a large number of wind direction plates 7a arranged in parallel, and blows out the wind from a slit 7b therebetween. Each wind direction plate 7a is inclined in one direction, and wind is blown obliquely from the slit 7b. Note that the slit 7b is designed so that pencils, high heels, and the like do not fall. A flange 7c is formed around the outlet member 7, and the outlet member 7 fitted in the circular hole 4a is rotatably supported by the panel member 4.

In FIG. 2, reference numeral 8 denotes a power supply unit such as the electric motor M. Reference numeral 9 denotes a stepping relay which changes the number of revolutions of the electric motor M,
The air volume and wind power are switched in multiple stages. Reference numeral 10 denotes a receiver, which receives an on / off command from a distant position, and a command signal such as air volume adjustment. 11 is a transformer.

Since the floor air-conditioning unit of the present embodiment is constructed as described above, the blower 5 can be operated by a remote controller, and the air volume thereof can be adjusted. The switch can be turned on / off directly by wire control or at hand.

The outlet member 7 is manually moved
Since it can be rotated 60 ° and blows out obliquely upward, as shown in FIG.
The wind direction can be set independently and freely. Therefore, the room for adjusting the airflow in the room is wider than before.

Further, in this embodiment, the outlet member 7
Are arranged at appropriate intervals.
As shown in (B), when the two outlet members 7 are directed to each other, the left and right winds buffer each other from an oblique direction, and are directed vertically upward on the floor. It is also possible not to do so. In this way, the wind direction and the wind force can be arbitrarily changed by appropriately causing the mutual winds to interfere with each other.

In the above-described embodiment, two outlet members 7 are arranged. However, three outlet members 7 may be arranged at respective apexes of an equilateral triangle, or four outlet members 7 may be fixed. The number and arrangement method of the outlet members 7, such as arrangement at each of the four corner positions of the quadrangle, are not limited to the above embodiment.

In the above embodiment, since the two outlet members 7 are arranged in the same duct portion 6, the wind force blown out from both outlet members 7 is the same, but the inside of the duct portion 6 is divided or branched. Alternatively, a wind force adjusting means such as a damper may be provided inside each outlet member 7 to change the wind force blown from each outlet member 7.

[0020]

(1) The duct is connected to the discharge section of the casing of the blower, and the blowout member is provided on the panel member at the position of the blowout port of the duct, so that the directivity is caused by the rotating blades of the blower. When entering the duct portion, the air flow in the casing having the above becomes high-pressure air that is static and non-directional within the duct portion, and exists as homogeneous and stable high-pressure air at any point in the duct portion.
Therefore, it is possible to blow out uniform and stable wind from the blowing member provided at any part of the duct portion. (2) The outlet member is configured such that a large number of wind direction plates inclined in one direction are arranged in parallel, and the wind blows obliquely from slits between the wind direction plates. Since it is rotatably provided on the panel member of the section, it is easy to control the wind direction and the like by the blowing member. (3) Since the installation height is 150 to 200 mm, the double floor can be lowered, and the ceiling height in the room can be sufficiently ensured even in an existing building. (4) Since the blower is ON / OFF and the air volume is adjusted by remote control, there are various operation variations and the usability is good.
