[0002]

2. Description of the Related Art In recent years, as office buildings have become more intelligent, many office automation equipment and the like have been installed indoors. The floor of such an OA equipment room has come to have a double floor structure in order to provide free access to various cables.

By the way, in order to improve the deterioration of the indoor environment due to the heat generation of the OA equipment, the double-floor space is also used as an air conditioning duct. Moreover, underfloor air conditioning units have been developed as a method of providing personalized air conditioning. This unit includes a fanless unit that pressurizes the space of the double floor and blows it out from the floor finishing material opening, and a unit with a fan that is a fan unit with an outlet. The present invention is
This is related to the latter unit with a fan in order to facilitate the application to existing buildings and achieve a more personalized air-conditioning orientation.

As a unit with a fan that has been developed so far, it is difficult to easily install it on the existing system floor, or the installation height is high and the double floor height is 3
There were problems such as a large size of 00 to 400 mm, inability to freely change the wind direction, and poor usability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 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 in a room where OA equipment and the like are provided, by supporting 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 an electric power cable for OA equipment and a telephone line or a communication cable are freely arranged.

U is a floor blowout air-conditioning unit, which is set at an arbitrary position of the floor panel 1a of the system floor 1, and uses the space S as a duct to blow out the air in the space S from the floor surface. Has become. In the present embodiment, the air in the space S is simply blown out for the purpose of preventing the heat generated from the OA equipment from staying in the room. However, for example, when ventilation or cooling / heating is required. The outside air is introduced into the space S, or a heat source device for cooling and heating is connected to the space S.

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

The panel member 4 is made of, for example, a fiber reinforced cement floor panel, which is low in cost and does not produce creaking noise. The panel member 4 has the same size as the floor panel 1a of the system floor 1, for example, a widely used module of 500 × 500 mm, and can be moved to a free position on the system floor 1 to be arbitrarily It can be set at an appropriate position by replacing the floor panel 1a.

The blower 5 is composed of a casing 5a, rotating blades 5b, an electric motor M, etc., and has a thickness dimension D.
Is designed to be thin, for example, 103.6 mm.
The rotary blade 5a is not limited to the plate fan as shown, but may be any conventionally known centrifugal type or axial type fan such as sirocco type, turbo fan, silent fan, axial flow fan, etc., but low noise. Fans are preferred.

The duct portion 6 is continuously connected to the discharge portion of the casing 5a, and the outlets 6a are formed at the upper two places 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 disk-shaped outlet member 7 is rotatably fitted in the circular hole 4a. As shown in the enlarged view of FIG. 3, the blow-out member 7 has a large number of wind direction plates 7a arranged in parallel and blows out the air from the slits 7b between them. Each wind direction plate 7a is inclined in one direction, and the wind blows obliquely from the slit 7b. The slits 7b should be designed so that pencils and high heels do not fall. A flange 7c is formed around the blow-out member 7 so that the blow-out member 7 fitted in the circular hole 4a is rotatably supported by the panel member 4.

In FIG. 2, reference numeral 8 is a power supply unit such as the electric motor M. Reference numeral 9 denotes a stepping relay, which can be changed by changing the rotation speed of the electric motor M.
Switch air volume and wind power in multiple stages. Reference numeral 10 denotes a receiver, which receives command signals such as an on / off command and an air volume adjustment from a remote position. 11 is a transformer.

Since the floor blowout air conditioning unit of this embodiment is constructed as described above, it is possible to operate the blower 5 and adjust the air volume thereof by the remote control. It should be noted that it is also possible to control by wire or turn the switch on and off directly by hand.

The outlet member 7 is manually set to 3
Since it can be rotated by 60 ° and is blown out obliquely upward, as shown in FIG. 4 (A),
The wind direction can be set independently and freely. Therefore, the range of airflow adjustment in the room is wider than in the conventional case.

Further, in this embodiment, the outlet member 7
However, since two pieces are arranged at appropriate intervals,
As shown in (B), when the two outlet members 7 are directed toward each other, the left and right winds buffer each other from an oblique direction and are directed vertically above the floor. It is also possible not to. Thus, by appropriately interfering the mutual winds, the wind direction and the wind force can be arbitrarily changed.

Although the two outlet members 7 are arranged in the above embodiment, the three outlet members 7 are arranged at the respective vertex positions of the equilateral triangle, or the four outlet members 7 are arranged in the regular shape. The number and arrangement method of the outlet members 7 such as the arrangement at each of the four corners of the quadrangle are not limited to those in the above embodiment.

Further, in the above-mentioned embodiment, since the two outlet members 7 are arranged in the same duct portion 6, the wind force emitted 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 emitted from each outlet member 7.

【The invention's effect】

1) It can be easily and inexpensively mounted on a system floor that has been widely used in the past. 2) Since the double floor can be lowered, it is possible to secure a sufficient ceiling height inside the existing building. 3) There are various variations of operation, and it is easy to use. 4) Since the blowing direction can be changed arbitrarily, the air conditioning is personal and comfortable.
