Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a so-called ceiling-embedded air conditioner, and more particularly to an air conditioner configured to allow adjustment of the mounting position of a blow-off panel.

[Conventional technology]

As shown in FIG. 3, a ceiling-embedded air conditioner is an air conditioner main body (hereinafter abbreviated as the main body) installed in a ceiling space 3 formed between a ceiling slab 1 and a ceiling material 2. ) 4 by suspending it using a hanging bolt 5 and an insert 6, and an air blowing panel 7 is installed corresponding to this embedding position.
is attached to the ceiling material 2 and exposed on the room 8 side.

Inside the main body 4, although not shown, a blower, a heat exchanger, a dew pan, etc. are built-in. The blowout panel 7 has a suction port 9 at the center and a blowout port 10 at the end.

Now, if the main body 4 and the blow-off panel 7 are formed integrally, the blow-off panel 7
Since the mounting position of the ceiling space 3 is uniquely determined, it becomes impossible to accommodate various dimensions of the ceiling space 3. Therefore, there is a device in which the blow-off panel 7 can be expanded and contracted relative to the main body 4 so that the installation can be adjusted. As shown in FIG.
The position of the blow-off panel 7 can be adjusted by slidably fitting the sliding duct 11 communicating with the blow-off panel 7.

[Problem that the invention attempts to solve]

The main problem with the above-mentioned conventional ceiling-mounted air conditioner is that the position adjustment range of the blowout panel 7 is limited to the sliding duct 1.
There is a limit to the adjustment range of the sliding stroke of No. 1, and the installation work requires a great deal of effort due to stiffness.

That is, the general installation method for a ceiling-embedded air conditioner is as follows. First, the main body 4
We carried out suspension work to ceiling slab 1 of
First, lay the base of the ceiling (hang the frame support 12 across the front of the ceiling, then attach the frame 13 with clips), third, attach the ceiling material 2, and fourth, attach the main body 4 and A hole is drilled in the ceiling material 2 corresponding to the mounting position of the blow-off panel 7, fifthly the ceiling base is reinforced, and sixthly the blow-off panel 7 is installed. Of the above construction works, 1st, 4th, 5th, 6th
Normally, the first construction is carried out by an equipment contractor, and the second and third are carried out by a construction company.

In the above construction procedure, as mentioned earlier, in conventional air conditioners of this type, the adjustment range of the blowout panel 7 was limited, so the lower position of the main body 4 was determined by the height dimension of the main body 4. If it exceeds the ceiling space 3, the main body 4 will end up hitting the edge support 12. Therefore, as a construction procedure, the ceiling work (see 2nd and 3rd) generally precedes the work, so the main body 4 is first hoisted to a position where it will not hit the ceiling, and after the ceiling work is completed, it is hung again, and then the piping to the main body 4 is connected. Construction work will have to be carried out, resulting in duplicate work. One way to solve this problem is to prepare blow-out panels that can be adjusted to fit the dimensions of various ceiling spaces 3, but preparing blow-out panels of various standards is complicated in manufacturing and packaging conditions. This is not desirable in terms of cost.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a ceiling-mounted air conditioner whose position can be adjusted to suit various ceiling spaces with a simple configuration without making any particular changes to the configuration of the main body or the blowout panel.

[Means for solving problems]

In order to solve the above problems, this invention
The air conditioner body is housed in the ceiling space formed between the ceiling slab and the ceiling material, and is connected via a sliding duct that is slidably fitted into the air outlet passage of the air conditioner body. In a ceiling-embedded air conditioner, the air conditioner is configured to include a blow-off panel that has an air blow-off port and is mounted exposed on the side surface of the room of the ceiling material, and is configured such that the mounting position of the blow-off panel can be adjusted; The present invention is characterized by comprising an intermediate duct which can be fitted into the sliding duct of the blow-off panel and whose other end can be fitted into the blow-out air passage of the air conditioner main body.

[Effect]

According to the above-mentioned present invention, by providing the intermediate duct whose one end in the axial direction can be fitted into the sliding duct of the blowout panel and whose other end can be fitted into the blowout air passage of the main body, the mounting screws, etc. The air outlet of the air outlet panel and the air outlet of the main body can be communicated with each other by a simple fitting action without using any special attachment parts, and therefore the adjustment range is expanded by the axial length of the intermediate duct. can do. As a result, there is no need to raise or lower the main unit during ceiling construction, and it can be installed in advance at a higher position than the roof fence that may come into contact with it, and subsequent adjustments can be made by sliding the intermediate duct and sliding duct. It is possible to improve the operation.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

FIG. 1 shows an embodiment of the present invention. Components that are the same as those in the conventional example shown in FIG. 3 are designated by the same reference numerals, and detailed explanation thereof will be omitted.

The parts in Fig. 1 that differ from Fig. 3 are the main body 4.
The main body 4 and the outlet panel 7 are connected to each other by interposing an intermediate duct 14 between the main body 4 and the outlet panel 7.

The intermediate duct 14 is made of styrofoam. This is because, while the intermediate duct 14 itself does not need to function as a support structure, it must have heat insulation properties since the temperature of the blown air must not fluctuate. Regarding the shape of the intermediate duct 14, the end 15 of the blowout panel 7 on the side of the sliding duct 11 is formed so that the sliding duct 11 is a male and the end 15 is a female so that the end 15 can be fitted with the blowout panel 7, and the blowout air of the main body 4 is The end 16 on the passage side is formed so that the end 16 is male and the blowing air passage is female so that they can be fitted together. This relationship may be the opposite of the above. Furthermore, each end 15, 16 of the intermediate duct 14 is preferably formed to be slidable in the axial direction with respect to the sliding duct 11 and the blowing air passage to be fitted. This is because if it is not made slidable, the adjustment range of the blow-off panel 7 will be uniquely determined by the physical dimension of the axial length of the intermediate duct 14. Of course, even with this, the adjustment range can be expanded compared to the conventional method. However, in order to make smoother adjustments in accordance with the on-site situation, it is preferable to make it slidable as described above. Moreover, since the intermediate duct 14 is actually made of styrene foam, cutting is easy. Therefore,
The dimensions may be adjusted by making the intermediate duct 14 somewhat longer and cutting it as necessary.
In this respect, there is an advantage that the intermediate duct 14 is made of styrene foam.

Next, in the above embodiment (FIG. 1), the intermediate duct 14 was explained as being provided individually for each sliding duct 11, but the present invention is not limited to this. That is, as shown in FIG. 2, it may be an integral intermediate duct 14A that surrounds each sliding duct 11 and the suction duct 15 from the suction port 9. Of course, in this case, the blowing air passage 16 and the suction air passage 17 must be formed in separate spaces internally. As for the construction materials, the exterior is formed from galvanized iron plates in order to maintain overall strength, and heat retention is ensured by attaching heat insulating material to the inner walls.
In this case, the sucked air will not be dissipated into the ceiling space, and since it is made of galvanized iron, it can be easily fabricated on-site.

[Effect of idea]

As described above, according to the present invention, there is provided a ceiling-mounted air conditioner whose position can be adjusted to suit various ceiling spaces with a simple configuration without the need to make any special modifications to the configuration of the main body or the blowout panel. I can do it.
