Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, an air conditioner 1 according to this embodiment is a ceiling-embedded air conditioner that is suspended and fixed in a ceiling space. An air inlet 3 which is an opening is formed in the center of the decorative panel 2, and a pair of outlets 4a and 4b are formed on both sides thereof.
The air sucked from the suction port 3 is heat-exchanged and then blown out from the air outlets 4a and 4b.

A central panel 6 is attached to the central portion of the decorative panel 2 corresponding to the suction port 3. When the central panel 6 is removed from the decorative panel 2, the inside of the filter chamber 20 and the inside of the main body 8 are exposed.

As shown in FIG. 3, a blower 5, heat exchangers 7a and 7b, and an electrical equipment box (not shown) for controlling the operation are housed in the main body 8 to blow the decorative panel 2. A pair of blowing passages 11a and 11b are formed along the longitudinal direction of the main body 8 at positions corresponding to the outlets 4a and 4b.

As shown in FIGS. 1 and 2, a pair of flanges 55 are formed in the main body 8 in the longitudinal direction. The flange 55 is provided with a filter chamber 20, which is a filter chamber, from a lower direction E. It is detachably attached with screws. The filter chamber 20 is a frame body and has four side surface portions 20a, 20b, 20c, 20d, and above the side surface portions 20b, 20d on two opposing short sides of these side surface portions. The first flange portions 30, 30 are integrally formed laterally. The flange portion of the box-shaped main body 8 is fixed to the first flange portions 30 and 30 with screws 56.

On the other hand, as shown in FIG. 2, the second flange portion 4 is provided below the short side surface portions 20b and 20d.
0 and 40 are provided separately from the filter chamber 20, and are attached by screwing.
The second flange portions 40, 40 are L-shaped in cross section, and one side portion of the second flange portions 40, 40 is a side surface portion 20 b, 20 d on the short side by the screw 60.
