Description

[Detailed Description of the Invention] This invention relates to an improvement of a ceiling-embedded air conditioner (hereinafter referred to as a cassette-type air conditioner).

This type of conventional cassette-type air conditioner is the first
It has a structure as shown in FIG. In other words, when fixing the main body 1 to the ceiling interior 3 and attaching the decorative panel 5 to the main body, one person supports the decorative panel 5 while another person supports the decorative panel 5.
Pass the bolt 8 through the central round hole 10 and attach the decorative panel 5.
are temporarily tightened to the main body 1, and then the other bolts 8 are fully tightened and installed as shown in Fig. 1.

In this case, multiple people are required to install the decorative panel, and it is difficult to tighten the holes because there is little play between the holes and the bolts.As shown in Figure 2, the decorative panel Since the position of the decorative panel 5 is determined, it is difficult to align the lines between the decorative panel 5 and the joints of the ceiling, resulting in poor aesthetics. For this reason,
When installing the main body 1, there were drawbacks such as having to redo the work unless the alignment with the ceiling joints was very carefully done.

This project was developed in view of these drawbacks, and the work of installing decorative panels is easy and can be done by one person.
This provides a device that allows ceiling joints to be aligned simply by adjusting the decorative panel 5.

An embodiment of this invention will be described below with reference to FIGS. 3 and 4. 1 is an air conditioner body installed in the ceiling 3 by hanging bolts 2, 4 is a ceiling opening, 5 is a decorative panel body, Reference numeral 6 denotes a suction grill, which is formed on the flat part of the decorative panel 5. Reference numeral 7 denotes a support, which is a mounting bolt 8 of the air conditioner main body 1.
A plurality of mounting holes 9 are provided, the diameter of which is larger by the necessary adjustment allowance. Reference numeral 10 denotes a mounting hole located approximately in the center of the support 7, which has the same diameter as the mounting hole 9 and has an opening 11 into which the mounting bolt 8 can be inserted. 1
Reference numeral 2 designates washers provided to prevent the heads of the bolts from coming out of the mounting holes 9 and 10 when the mounting bolts 8 are tightened.

In the structure configured as described above, when attaching the decorative panel 5 to the main body 1, first temporarily tighten the central bolt 8 to the main body 1, and then tighten the mounting hole 10 of the central support 7 of the decorative panel 5. opening 11 of
The decorative panel 5 is temporarily fixed by passing the shaft of the bolt 8 through the screw, and then sliding it so that the bolt 8 comes to a predetermined position. Thereafter, as shown in FIG. 4, the decorative panel 5 can be adjusted longitudinally, horizontally, and in the rotational direction separately from the main body 1 within the adjustment allowance of the mounting holes 9 and 10 using the temporarily fixed bolts 8 as support. The decorative panel can be aligned with the ceiling joint while it is temporarily fixed, and once the position is determined, the work is completed by simply tightening the other bolts 9.

As described above, the installation hole of the decorative panel can be temporarily fixed approximately in the center, and even if the main body 1 and the ceiling opening 4 are misaligned, the decorative panel
Since the mounting holes 9 and 10 provided in the panel are made larger by the necessary adjustment allowance, it is possible for one person to install the decorative panel 5, and it is also adjustable in the front and back, left and right, and rotational directions. It is also easy to align the decorative panel 5 and the ceiling joint. In other words, work efficiency is improved, installation time is shortened, and installation costs are also reduced.
