Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to the installation of an indoor unit of a ceiling-mounted air conditioner.

Conventional technology Conventionally, a ceiling-mounted air conditioner has the following features, as shown in Figure 5:
A reinforcing square beam 12 is fixed to the roof beam 11, which is a structural part in the ceiling, and a hanging bolt 13 is hung from the reinforcing square beam 12. After fixing with a nut to a hanging fitting 15 provided on the indoor unit main body 14, the air is removed. Suction port.

A decorative grill 16 having an air outlet is attached to the indoor unit main body 14.
It can be fixed and installed.

Problems that the invention aims to solve The problems with the above conventional example will be explained with reference to FIG.

FIG. 6 is a diagram (viewed from inside the ceiling) showing the relationship between the installation dimensions of the ceiling-mounted air conditioner shown in FIG. Relative positioning of opening (cxd) and decorative grille 1
Indoor unit main body 1 to eliminate the gap between 6 and the ceiling surface
4 and the ceiling surface I7 (indicated by the difference e between the upper surface of the hanging bracket 15 and the lower surface of the ceiling 17 in the figure), etc., the installation work was extremely complicated and difficult, and the construction time was required. .

Means for Solving the Problems In view of the above-mentioned problems, the present invention constitutes an indoor unit by engaging an indoor unit main body housed in the ceiling with a decorative panel having an air inlet and an air outlet, The indoor unit main body is supported by a ceiling plate.

Effect: The above means eliminates the need for installing and constructing hanging bolts for hanging the indoor unit, and also eliminates the need for adjustment to eliminate the gap between the decorative grill and the ceiling surface.

Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 to 4.

FIG. 1 is a diagram showing the installation structure of an indoor unit of an air conditioner on the ceiling. Inside the ceiling is a hanging tree 7 that hangs the ceiling board 3 from the roof beam 5, and a field that is supported by the hanging tree 7 and serves as the frame of the ceiling board 3. It is composed of a rim 6 and the like.

■ is the indoor unit itself, with a heat exchanger inside.

A blower fan, a blower motor, a drain pan, a drain pump, electrical components, etc. (all not shown) are housed therein.

At the bottom of the indoor unit main body 1 are provided four support plates 4 that are horizontally rotatable. A decorative grille 2 having an air inlet 8 and an air outlet 9 is fixed to the indoor unit main body 1 with screws to form an indoor unit.

FIG. 2 is a perspective view of the support plate 4. A constriction part is provided at the bottom of the outer shell of the indoor unit main body 1, and the support plate 4 is fixed with screws 10. After lifting it further into the ceiling, the support plates 4 provided at four locations are rotated 90 degrees outward, so that the support plates fit into the constricted portions. Then, when the indoor unit body 1 is lowered a little, the support plate 4 is supported by the ceiling plate 3, and the temporary installation of the indoor unit body is completed. Then, tighten the screws 10 to completely fix the support plate 4.

FIG. 3 is a diagram showing a cross section AA in FIG. 2.

After the temporary installation of the indoor unit is completed as described above,
Position the indoor unit body and the ceiling opening.

Figure 4 shows the indoor unit main body 1 and the ceiling opening (CxD)
This is a diagram showing the positional relationship of the decorative grille 2 and the decorative grille 2 as seen from inside the ceiling.
Shift and adjust the indoor unit main body l in the horizontal direction. Finally, the decorative grille 2 is screwed onto the indoor unit main body from below, and the installation work is completed.

As described above, the rotatable support bracket 4 is provided at the bottom of the indoor unit main body 1, and the indoor unit main body I can be supported by the ceiling plate 3. This eliminates the need for aligning openings, tightening bolts when hanging the indoor unit, and adjusting the height of the indoor unit to the ceiling, making installation work much easier and greatly improving work efficiency.

In addition, due to recent technological advances, indoor units have become smaller and lighter, making it possible to install them even on ceilings that are somewhat weak.

Effects of the Invention As described above, the present invention configures an indoor unit by engaging an indoor unit main body housed in the ceiling with a decorative panel having an air inlet and an air outlet, and By supporting the ceiling board, you can perform tasks such as installing conventional hanging bolts, aligning the hanging bolt mounting position with the ceiling opening, tightening the bolts when hanging the indoor unit, and adjusting the height between the indoor unit and the ceiling surface. This eliminates the need for installation work for ceiling-mounted air conditioners, which was previously complicated and difficult.
