BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner installation device for installing an indoor unit in a ceiling, and more particularly to an air conditioner installation device that simplifies the installation of an indoor unit.

0003

2. Description of the Related Art In general, this type of air conditioner has an indoor unit installed in the ceiling of a building such as a residence to hide its existence, and has been increasingly used in recent years as the interior design of residences has increased.

[0004] However, since this type of air conditioner has its indoor unit built into the ceiling of the house, it is difficult to install the indoor unit after the construction work of the house is completed, and it is difficult to install the indoor unit during the construction work. It is common to install them in conjunction with each other.

For example, an example of a conventional indoor unit installation device is shown in FIGS. 6 and 7. This is the ceiling plate 1 inside the ceiling 2 above the ceiling plate 1 of the house.
7, for example, four hanging bolts 5a, 5b, 5c,
5d are suspended, and their upper ends are fixed to a structure such as a beam inside the ceiling 2.

[0006]The indoor unit 3 has hanging ears 4a to 4.
The lower ends of each of the hanging bolts 5a to 5d are inserted into d, and the hanging bolts are directly tightened and fixed with flanged nuts 6a, 6b, 6c, and 6d. A plurality of tongues 7, 7, . . . are provided at each corner of the lower surface of the indoor unit 3 to project outward in the horizontal direction.

[0007]

[Problem to be Solved by the Invention] However, in such a conventional installation device, since the indoor unit 3 is installed before the ceiling panel 1 is installed, it is difficult to select the installation location for the indoor unit 3. In addition, a large amount of construction work is required, such as installation, formation of air supply/exhaust openings in the ceiling plate 1, and subsequent adjustment of the installation position of the indoor unit 3.

[0008] Therefore, there is a problem that the number of meetings between air conditioner-related workers and construction workers is extremely large, and the construction efficiency is not high.

That is, the indoor unit 3 is attached to the hanging bolt 5a.
~5d, the position of the opening 1a of the ceiling plate 1 is determined based on the indoor unit 3 itself, so if the opening size of the ceiling plate 1 is incorrect, for example, there is no space for drain pipe or refrigerant piping service, This requires a great deal of time and effort to adjust, and also requires a great deal of effort to correct when there is a discrepancy in the surface level between the lower surface of the ceiling board 1 and the lower surface of the indoor unit 3.

Furthermore, since openings are formed in the ceiling plate 1 while the indoor unit 3 is installed, dirt and dust generated during construction may enter the electrical components and heat exchanger, causing the interior of the indoor unit 3 to become dirty. Otherwise, problems such as damage or peeling of the insulation material are likely to occur. Furthermore, in some cases, the periphery of the opening 1a of the ceiling board 1 may not be fixed sufficiently and become unstable, or a gap may occur between the ceiling board 1 and the opening 1a, requiring a high level of skill from the installer. , construction costs will also increase.

[0011] Therefore, the present invention was made in consideration of the above circumstances, and its purpose is to provide an air conditioner that allows easy installation of an indoor unit and also simplifies the installation of ceiling panels. Our objective is to provide installation equipment for harmonizers. [Structure of the invention]

0012

[Means for Solving the Problems] In order to solve the above problems, the present invention is constructed as follows.

In other words, the present invention provides an air conditioner installation device for installing an indoor unit of an air conditioner in the ceiling of a building, in which the outer peripheral surface of the indoor unit is surrounded by a hanging tool suspended in the ceiling. The present invention is characterized in that a frame is attached, and stoppers are fixed to the inside of each corner of the frame, on which each corner of the lower surface of the indoor unit is placed.

[0014]

[Function] Since the frame has a frame structure, it is light, which makes it easy to attach it to a hanging tool. Moreover, before installing the ceiling board, the frame is installed at the height at which the ceiling board should be installed, so when installing the ceiling board, the ceiling board is set based on the outer circumference of the frame. The tensioning can be done by matching the actual parts, which simplifies the tensioning work and also makes it easier to attach to the frame.

When installing the indoor unit on the frame, after installing the ceiling board, stand the indoor unit up slightly, insert the entire unit into the ceiling through the internal space of the frame, and then move the indoor unit horizontally. By laying the indoor unit on its side and placing each corner of the lower surface of the indoor unit on the stopper at each corner of the frame, the indoor unit can be supported by the frame and the lower surface of the indoor unit can be leveled at the same time.

In other words, by placing each corner of the indoor unit on each stopper of the frame, the indoor unit can be installed inside the ceiling, so installation of the indoor unit is easy, and the indoor unit is relatively compact. If the work is light, it can be done by one worker, increasing work efficiency.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to FIGS. 1 to 5.

FIG. 2 is a longitudinal cross-sectional view of one embodiment of the present invention, and FIG. 1 is a perspective view of its main parts. Before the ceiling board 11 is stretched, a rectangular frame-shaped hanging frame 14 is suspended using, for example, four hanging bolts 13a, 13b, 13c, and 13d.

Each hanging bolt 13a to 13d is attached to a hanging frame 14.
It is arranged so that it hangs slightly outward from each corner of the
It consists of a bolt with a thread groove carved in its axial direction, and its upper end is fixed to a structure such as a beam (not shown) inside the ceiling 12.

On the other hand, the hanging frame 14 is constructed of a rectangular frame made of an elongated plate member made of metal or the like and having a required width so as to surround the four outer peripheral surfaces of the indoor unit 15 of the air conditioner. The external dimensions are adapted to the dimensions of the opening 11a of the ceiling plate 11.

The hanging frame 14 also has substantially disk-shaped hanging ears 16a, 16b, 16c, and 16d fixed to the outside of each corner by welding or the like so as to project outward in the horizontal direction. Each hanging bolt 13a is attached to 16a to 16d.
- 13d is inserted through the insertion hole.

Further, triangular plate-shaped stoppers 17a, 17b, 17c, and 17d that match the shape of the triangular internal space are fixed to the inside of the bottom surface of each corner of the hanging frame 14 by welding or the like.

The hanging frame 14 is constructed by inserting the lower ends of the hanging bolts 13a to 13d into the insertion holes of the hanging ears 16a to 16d, and then tightening the insertion ends of the hanging bolts 13a to 13d. Tighten to adjust the hanging height with nuts etc.
The hanging frame 14 is suspended inside the ceiling 12 so that the lower surface of the hanging frame 14 substantially matches the lower surface of the ceiling 11. This hanging work is very easy because the hanging frame 14 has a frame structure and is light.

After the hanging frame 14 is hung, the ceiling board 11 is stretched, but after all the building work on the house side including these is completed, the indoor unit 15 is hung as follows. Install it on frame 14.

First, as shown in FIG.
is slightly raised and inserted from below the ceiling plate 11 through the opening 11a into the ceiling interior 12 side.

After that, as shown in FIG.
5 is pushed up onto the hanging frame 14, the indoor unit 15 is laid down laterally (horizontally) as shown in FIG.
7d, and if necessary, fix the indoor unit 15 to the hanging frame 14 with an appropriate fixture.

[0027] As a result, the lower surface of the indoor unit 15 having the inlet, outlet, etc. can be easily exposed into the room through the opening 11a of the ceiling plate 11. After the indoor unit 15 is installed, a drain pipe (not shown), a refrigerant pipe, an internal/external connecting wire, a power supply, etc. are connected, and then the opening 11a of the ceiling plate 11 is opened.
Then, a decorative panel (not shown) having openings corresponding to the inlet and outlet of the indoor unit 15 is attached, and the work is completed.

Therefore, according to this embodiment, since the hanging frame 14 has a frame structure and is light, the hanging bolts 13 of the hanging frame 14 are
Installation to a to 13d becomes easy.

Furthermore, since the ceiling board 11 is stretched after the hanging frame 14 is hung, the ceiling board 11 is stretched based on the outer periphery of the hanging frame 14.
can be set up.

Therefore, the hanging frame 14, the ceiling plate 11, and the opening 11a can be easily and reliably aligned, which clarifies the work of determining the opening dimensions of the ceiling plate 11 and the work of aligning the ceiling surfaces. This will make the work easier, and the work efficiency of these construction operations will be significantly improved. Further, since the indoor unit 15 can be easily installed as if it were placed on the hanging frame 14, this installation work can be performed by one person if the indoor unit 15 is relatively light.

Furthermore, since the indoor unit 15 can be installed after the ceiling board 11 is stretched, there is no problem such as dirt and dust generated during construction work entering the indoor unit 15, and dirt can be removed. It can also be prevented.

Furthermore, since the configuration according to this embodiment is relatively simple, it is possible to reduce the cost of installation work for the indoor unit 15.

[0033]

[Effects of the Invention] As explained above, the present invention makes it possible to clarify the work of determining the opening dimensions of the ceiling plate and to facilitate the work of aligning the ceiling surfaces, etc., before installing the indoor unit of the air conditioner. Therefore, the installation of the indoor unit becomes easy, and the construction efficiency can be significantly improved.

[0034] Furthermore, it is possible to install the indoor unit after opening the ceiling plate, thereby preventing the indoor unit from getting dirty.
This has many practical effects such as shortening the construction period and effectively achieving a good ceiling finish.
