Reference numeral 25 denotes a step portion on the lower surface of the main body 1, which is provided adjacent to the suction port 3.
Reference numeral 26 is a recess formed by the partition plate 22 and the drain pan 24, and is provided between the blow-out port 4 and the suction port 3. 27 is a mounting screw with washers 28 provided at the four corners of the lower surface of the main body 1, 29 is a decorative panel, and a fixing plate 31 having a plurality of fixing darma holes 30 corresponding to the mounting screws 27 with the washer 28 is provided. . Reference numeral 32 denotes a guide side wall, which is integrally formed with the decorative panel 29 so as to engage with the stepped portion 25 and the recessed portion 26 and to come into contact with the air outlet 4. Reference numeral 33 is a wind direction plate provided on the outlet grill 8.
The same or corresponding parts as those in the conventional example are designated by the same reference numerals.

Next, an installation procedure of the main body 1 and an installation procedure of the decorative panel 29 will be described.

The ceiling-embedded air conditioner main body 1 is arranged behind the ceiling 21 by the hanging bolts 5, and is installed so that the lower surface of the main body is exposed to the room side from the opening 20 of the ceiling 21.

The decorative panel 29 is temporarily fixed by fitting the fixing darma hole 30 into the mounting screw 27 with the washer 28 attached to the lower surface of the main body 1, and then the guide side walls 32 of the decorative panel 29 are respectively stepped 2
5, Position the recess 26, the outlet 4 in contact with each other,
It is attached to the main body 1 by tightening the attachment screw 27. The ceiling opening 20 is thus closed.

In FIG. 5, reference numeral 7 denotes a box-shaped suction grille having a side edge 34 on the periphery thereof, and a spindle 35 for rotatably mounting it on the decorative panel 29 is provided. A pair of locking tongues 36 are provided inside the side edge 34 near the support shaft.
A pair of fitting holes 37 is provided in the side edge 34a facing the 35.

6 and 7, reference numeral 13 denotes a filter, which has a structure in which a net 16 is integrally attached by welding or the like to a lattice frame composed of an outer frame 14 and an inner intermediate frame 15. Reference numeral 38 denotes a protrusion provided on both frame edge surfaces of the outer frame 14 so as to contact the retaining tongue 36 when the filter 13 is inserted under the retaining tongue 36 of the suction grill 7, and 39 denotes the outer frame 14. Fitting pieces provided at both ends of one side are inserted and locked in the fitting holes 37 of the suction grill 7. Reference numeral 40 denotes a pair of handles, which are adjacent to the fitting piece 39 of the outer frame 14 and are integrally provided upright on the edge portion.

Next, the procedure for installing and removing the filter will be described.

First, the suction grill 7 is detached from the decorative panel 29 at one end and rotated, and is supported by the support shaft 35 at the other end.
The protrusion 38 side of the outer frame 14 of the filter 13 is fixed to the suction tongue 7 of the suction grill 7.
Inserted under 36, the protruding piece 38 is brought into contact with the locking tongue 36, and further force is applied to bend the filter 13 itself, and the fitting piece 39 is fitted into the fitting hole 37 of the suction grill 7. Mating. By doing so, the filter 13 is restored from the curved state and is smoothly attached to the suction grill 7.

As shown in FIG. 8, the filter 13 attached as described above is a filter in which the handle 40 is pulled up in the protruding direction (upward), and the projecting pieces 38 on both sides are brought into contact with the locking tongue 36 of the suction grill 7.
Bend 13 longitudinally. Then, the fitting piece 39 of the filter 13 comes out of the fitting hole 37 of the suction grill 7, and the filter 13 comes off the suction grill 7.

FIG. 9 shows another aspect of the pair of fitting pieces 39 described above. That is, the pair of fitting pieces 41 shown in FIG.
The outer frame 14 is attached to the tips of the pair of fitting pieces 39 in FIGS. 6 and 8.
Is provided with inclined surfaces 41a inclined in opposite directions with respect to the side surface of the. That is, the pair of fitting pieces 41
Is gradually shortened toward the projected corner side of the filter 13. In this way, the fitting piece 41 can be smoothly removed from the fitting hole 37, so that the filter 13 can be attached to and removed from the suction grill 7 smoothly.

〔The invention's effect〕

As described above, according to the present invention, the step portion is formed on one side of the lower surface of the main body adjacent to the suction port, and the recess is formed by the partition plate and the drain pan, and the step portion is formed on the decorative panel. Since the guide side wall that engages with the recess and the darma hole for fixing the main body to the main body are provided, the positioning and attachment of the decorative panel to the main body can be performed easily and reliably in a short time.

In addition, the outer frame of the filter is integrally formed with the engaging tongue provided on the suction grill and the protruding piece and the engaging piece that engage with the fitting hole. By inserting the fitting piece into the fitting hole of the suction grill and vice versa, the fitting piece can be securely and smoothly attached to and removed from the suction grill. In particular, when the fitting piece of the filter is shortened toward the projected corner side of the filter, the attachment / detachment is more reliable and smooth.
