JPH04187936A - Air outlet of air conditioner with luminatire - Google Patents

Abstract

PURPOSE:To attain both optimum air-condtioning and illuminating effects by a method wherein an illuminator is mounted in the middle of a front grille, and air chambers communicating with air outlets are located on both sides of the illuminator and air-tightly connected so that the luminatire is held between the air chambers. CONSTITUTION:Conditioned air passes through left and right duct connectors 5a and 5b and is sent into a room from air outlets 2a and 2b on the left and right sides of a front grille 1 via lower openings 4a and 4b on the left and right sides of a U-shaped air chamber 4. The U-shaped air chamber 4 is hung on a beam 16 by a hanger frame 6 which is fixed on opposite walls in a middle space 4c of the U-shaped air chamber 4. The hanger frame 6 does not come in contact with an luminatire 3 and has a construction capable of satisfactorily enduring the weights of the front grille 1, the U-shaped air chamber 4 and the luminatire 3. The luminatire 3 is fixed by hanger bolts 9c in hanging state on a hanger plate 7 that overlaps and is attached on the top walls of the U-shaped air chamber 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an improvement of an air blowing device in an air conditioner with a lighting device.

[Conventional Techniques] In recent years, the demand for recessed air conditioners has increased from the standpoint of interior design and installation space, and as a result, the installation locations have diversified into ceilings and walls.

For example, FIGS. 7 and 8 show the conventional air conditioner shown in Japanese Utility Model Publication No. 63-40732, which is embedded in the ceiling.

In Fig. 7, (15) is a ceiling plate, in which a suction chamber (12), an air conditioner (10), and a blow-out chamber (13) are respectively mounted on beams (16). The suction chamber (12) and the air conditioner (10) and the outlet chamber (13) and the air conditioner (10) are housed and fixed in a suspended state by a hanging bolt (9) fixed to the duct ( 8) are connected to form a series of air channels. In addition, the suction chamber (12
), a suction grill (11) is fixed to the blow-off chamber (13), a blow-off grill (14) is fixed to the blow-off chamber (13), and each grill is exposed on the lower surface of the ceiling board.

Fig. 8 is another example showing a state in which it is embedded in a part of the ceiling where the air conditioner (11) is installed. The blow-off chamber (13) and blow-off grill (14)
is fixed to the vertical wall surface of the ceiling board (15).

Furthermore, Fig. 9 shows a conventional embedded layer air conditioner (10), suction grill (11), duct (8), and blowout chamber (13).
) is a sectional view of the entire room in which the outlet grill (14) is arranged in the ceiling, and the air conditioner (10) installed in the ceiling.
The air in the room taken in by the air conditioner (10)
The heat is exchanged inside the duct (8), the blowing chamber (1
3) and is blown into the room from the blow-off grill (14).

On the other hand, the lighting in the room is provided by a lighting fixture (3) installed on the ceiling surface, completely unrelated to these.

[Problems to be Solved by the Invention] Conventional recessed air conditioners and lighting fixtures are installed as described above. In many cases, the installation positions of the lighting equipment and air conditioning related components overlap, and it is necessary to shift either the lighting equipment or the air conditioning related components from the optimal position, resulting in a decrease in the efficiency of either one. Furthermore, since each piece of equipment has to be installed separately, it takes a lot of time to work, and there are also problems in that it is necessary to drill holes in the ceiling board for each piece of equipment.

This invention was made to solve the above problems, and aims to optimize both the air conditioning effect and the lighting effect.

[Means for Solving the Problem] In the case of the present invention, a lighting fixture is arranged in the center of the front grill, and each air outlet hole located on both sides of the lighting fixture is provided with a lighting fixture provided in a common air conditioner. Each air chamber communicated with the air outlet is airtightly connected to sandwich the lighting equipment.

[Function] In the case of this invention, the lighting equipment and the air chamber can be arranged together in one optimal location.

[Example] An example of the present invention will be described below. That is, in FIGS. 1 to 4, (1) is the front grill directly attached to the ceiling plate (15), (2a) and (2b) are the air outlets provided on the left and right opposite sides of this front grill, (3)
is an opening (2c) located in the center of the front grille so as to be located between these air outlets (2a) and (2b).
(4) are the left and right lower openings (
4a and 4b are U-shaped air chambers that are airtightly connected to the left and right air outlets (2a and 2b) provided in the front grille (1), respectively, (4c) is the central space, and (5a) (5b) is a connecting part of the left and right ducts which are arranged in parallel on one side wall common to this air chamber and set to the same ventilation resistance condition, and (6) is a U-shaped air chamber (4).
) is a rectangular hanging frame fixed to the opposite inner wall of Hole (a)
) are provided symmetrically. (7) is the above hanging frame (
6) Suspension of the lighting fixture (3) located above and superimposed and fixed on the top wall of the U-shaped air chamber (4) so as to straddle the left and right lower openings (4a) and (4b) from above. The plate (9c) is a hanging bolt for the lighting fixture (3) suspended from this hanging plate (7).

FIG. 5 is a side view showing an embodiment in which the air blowing device of the present invention configured as described above is installed in a ceiling space together with an embedded layer air conditioner (10).

Next, the operation will be explained. In other words, the conditioned air that is sucked in from the suction grill (11) of the embedded layer air conditioner (10) and sent through the air duct (8) passes through the left and right duct connecting parts (5a) and (5b), forming a double-shaped air conditioner. Through the left and right lower openings (4a) (4b) of the air chamber (4),
Left and right air outlets (2a) (2b) of the front grill (1)
) is sent into the room.

At this time, the U-shaped air chamber (4) has the above-mentioned hanging frame (
6), and this hanging frame (6) does not come into contact with the lighting equipment (3), and is suspended from the front grille (1) and the U-shaped air chamber (4). , the structure is sufficient to support the weight of the lighting fixture (3), and the lighting fixture (3) can be mounted using the above-mentioned hanging plate (7), which is superimposed and fixed on the top wall of the U-shaped air chamber (4). ) is fixed in a suspended state with a separate hanging bolt (9c).

In the above embodiment, a case was explained in which the air chamber was integrated into a U-shape, but as shown in another embodiment in FIG. You can.

[Effects of the Invention] Since the air blowing device of the air conditioner with lighting equipment of the present invention is configured as described above, the air chamber and the lighting equipment can be installed together at an optimal location on the front grill, Both can be used with maximum efficiency. Furthermore, by holding the air chamber and the lighting fixture separately, the installation work for each is facilitated, and the installation and removal of the lighting fixture is extremely easy.
