Some air purifiers are selectively mounted on the main body case, and the air purifier and the decorative panel are mounted in order on the main body case, or only the decorative panel alone. That is, the decorative panel must be attachable to both the main body case and the air purifier.

As a conventional technique which satisfies this demand, Japanese Utility Model Laid-Open Publication No. 2-137626 is known.
The mounting structure as shown in the figure is adopted. In FIG. 9, reference numeral (60) denotes a main body case, (61) denotes an air purifier frame, (62) denotes a decorative panel frame, and (63) denotes a decorative panel used when the air purifier is equipped. It is a mounting plate.

[0004] When the air purifier is not provided, the horizontal frame (64) of the frame (62) is abutted against the joining wall (65) on the lower surface of the case from below, and screws are inserted through screw holes (66). Is screwed into the female screw body (67). When an air purifier is provided, the machine frame (61) is fastened to the joining wall (65), and the mounting plate (63) is fixed to the machine frame (61) via the notch (68). Then, the horizontal frame (64) of the frame (62) is screwed to the mounting plate (63).

[0005] Further, the air purifier and the decorative panel include:
Each of the four screw holes (69) and (66) is fastened with screws through four screw holes (69) and (66). 66) is a keyhole-shaped so-called daruma hole, and a female screw body (67),
The screws temporarily assembled in (70) can be temporarily assembled by hooking a pair of daruma holes.

[0006]

In the above-described mounting structure of the decorative panel in the ceiling-mounted type air conditioner, a pair of round hole-shaped screws are added to the temporarily assembled screws in both the air cleaner and the decorative panel.
