Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an improvement in the structure of a ceiling-mounted air conditioner.
[0002]
2. Description of the Related Art A ceiling-embedded air conditioner is constructed by attaching a ceiling panel to the lower surface of a box-shaped unit body containing a heat exchanger, a fan, a fan motor, and the like. An inlet is formed, and an outlet is formed around the inlet.
[0003]
In such an in-ceiling type air conditioner, the unit body is supported by suspension bolts suspended from the ceiling of the building, and is suspended from the ceiling. At this time, in general, the ceiling panel is fitted into the opening of the ceiling plate of the building, and the unit main body of the ceiling-embedded air conditioner is invisible from the outside.
[0004]
By the way, in some buildings, there is no ceiling plate, and the unit body of the ceiling-mounted air conditioner suspended from the ceiling may be exposed to the outside. The unit body is a solid steel plate whose outer surface is unpainted and heat-insulating material is stuck on the surface, so when the unit body is exposed to the outside, the beauty of the ceiling-mounted air conditioner May be impaired.
[0005]
For this reason, for example, reinforcing metal fittings for attaching a decorative panel are provided at the outer peripheral position on the back surface side (upper surface side) of the ceiling panel, and the decorative panel is fixed to these reinforcing metal fittings and stands upright. These standing decorative plates cover the outer periphery of the unit main body so that the unit main body is not exposed (for example, Patent Document 1).

[0027]
The left and right edges of two facing decorative plates 31 and 33 among the decorative plates 31 to 34 are bent inward at right angles, and a plurality of screw holes h and h for screw tightening are formed in these bent pieces 41. Have been. In addition, a plurality of screw holes j, j for inserting screws are formed on the left and right edges of the other two decorative plates 32, 34 so as to correspond to the screw holes for screw tightening. The decorative board 34 is connected to the decorative boards 31 and 33 and the decorative board 32 is connected to the decorative boards 31 and 33 by fixing the screw holes j to the screw holes h for tightening.
[0028]
The upper edges of the decorative plates 31 to 34 are bent inward at right angles, and two screw holes m and m for screw tightening are formed in these upper bent pieces 43. Then, a reinforcing top plate 36 is attached to the upper portions of the decorative plates orthogonal to each other through the screw holes m, m. Two screw holes n, n are formed at both ends of the reinforcing top plate 36, and the screw holes n, n and the screw holes m, m of the adjacent decorative plate are combined, so that the reinforcing top plate 36 is adjacent. It is fixed over two decorative boards. As a result, the four decorative boards 31 to 34 are reinforced with each other, and the square frame is kept in a good state.
[0029]
One decorative plate 31 of the four decorative plates 31 to 34 is provided with U-shaped insertion ports 44 and 45 through which the drain pipe 16 and the refrigerant pipes 17 and 18 are inserted. After the decorative plate 31 is inserted through the pipes 16, 17, and 18, the sealing plate 46 for the drain pipe and the sealing plate 47 for the refrigerant pipe that cover the empty portions of the insertion ports 44 and 45 are attached with mounting screws. .
[0030]
In this manner, the decorative plates 31 to 34 are fixed to the side plates 6a to 6d of the unit main body 2, and the decorative plates 31 to 34 cover the side plates 6a to 6d of the unit main body 2 and move the air conditioner 1 downward. When viewed from above, the unit main body 2 is not exposed. Furthermore, decorative screws are used for all the mounting screws for attaching the decorative plates 31 to 34, and the screw holes g and g of the decorative plates 31 to 34 are respectively provided at fixed positions, so that the appearance of the air conditioner 1 is improved. I do.
[0031]
Next, a procedure for assembling the decorative plate and the reinforcing top plate will be described.
[0032]
The decorative boards 31 to 34 described above are assembled after the installation of the ceiling embedded type air conditioner 1 and the outdoor unit is completed. First, the fixing brackets 36 are attached to the four side plates 6a to 6d of the unit body 2 with decorative screws. Next, the decorative plates 31 to 34 corresponding to the respective side plates 6a to 6d are attached to the fixing bracket 36 with decorative screws, and both ends of the two decorative plates 32 and 34 are both end portions of the other two decorative plates 31 and 33. Attach it with a decorative screw. The sealing plate 44 for drain piping and the sealing plate 45 for refrigerant piping are fixed to the decorative plate 31 with decorative screws. Then, the four reinforcing top plates 36 are attached between the orthogonal decorative plates 31 to 34 with decorative screws, and the assembly of the decorative plates 31 to 34 is completed.
[0033]
When these decorative plates are assembled to the side plate of the unit main body, the following effects can be obtained.
[0034]
The decorative plates 31 to 34 of the ceiling-embedded air conditioner 1 are attached to the side plates 6a to 6d via the fixing brackets 35, respectively. Is adhered, it is difficult for vibrations and sounds from the unit body 2 to be transmitted to the decorative plates 31 to 34, and the influence on the outside can be reduced. Further, since the heat from the unit main body 2 is not easily transmitted, the air conditioning ability can be sufficiently exhibited.
[0035]
Further, since the fixing bracket 35 is provided with the convex mounting portion 35b, the distance between the decorative plates 31 to 34 and the side plates 6a to 6d is maintained, and the suspension bolts 22, 22. -The possibility of contact with the contact can be reduced. The decorative panels 31-34 have a structure that is resistant to warping and distortion due to external pressure, since both ends of the decorative panels 31-34 are fixed with screws at the ends and the upper side is fixed with the reinforcing top plate 36. Can be.
[0036]
The decorative panels 31 to 34 of the present embodiment are not erected on the ceiling panel 3 like the conventional decorative panels 31 to 34, but are attached to the side panels 6a to 6d of the unit body 2 and Since a gap is provided between the ceiling panel 3 and the ceiling panel 3, the load is not applied, and the ceiling panel 3 is warped or distorted, and the durability of the boss portion 24 is improved.
[0037]
In addition, when the ceiling panel is detached from the unit main body, it is not necessary to perform the work of detaching the decorative panel (or detaching the ceiling panel from the unit main body while the decorative panel is attached), and the work of attaching and detaching the ceiling panel 3 is not necessary. Can be facilitated.
[0038]
As described above, the present invention has been described based on one embodiment. However, the present invention is not limited to this, and can be appropriately modified and implemented without departing from the gist.
[0039]
In the ceiling-mounted air conditioner, a plurality of types of units having the same vertical and horizontal dimensions but different height dimensions of the unit main body 2 and different air-conditioning capacities are designed, and the height of the decorative boards 31 to 34 is reduced. By designing according to a model having a high height, the decorative boards 31 to 34 can be used in common for a plurality of types of models, and the design can be saved.
[0040]
【The invention's effect】
As described above, according to the ceiling-embedded air conditioner according to the present invention, since the decorative member is disposed so as to cover the outside of the unit body, the ceiling-embedded air conditioner is Even when the camera is installed on the ceiling of a building with the camera exposed, the appearance can be improved.
[0041]
In addition, the decorative member is attached to the side plate of the unit main body via a fixing tool, and a heat insulating and vibration isolating material is attached to the fixing surface of the fixing member on the contact surface with the unit main body. Can be reduced, and the heat conduction between the unit body and the outside of the machine can be reduced to reduce heat loss.
[0042]
In addition, since the fixture has a convex mounting portion, the distance between the decorative member and the side plate of the unit body is maintained, and the possibility of contact with the suspension bolt due to the distortion of the decorative member can be reduced, and the stability can be improved. Can be installed.
