Attach to.

[Problem to be solved by the invention]

Conventional ceiling-mounted air conditioners are constructed as described above, so in order to attach the decorative panel, screws must be secured in multiple places, and the screw holes on the decorative panel and the screw holes on the main body must be tightened. It took a long time to position the machine, and the work had to be done at a high place, so there were problems with poor workability.

Furthermore, in order to attach the filter, the locking piece must be inserted into the locking hole and the fitting hole of the suction grill, so there is a problem that the filter cannot be attached or removed reliably and smoothly.

This invention was made to solve the above-mentioned problems, and it is possible to easily and reliably position and attach a decorative panel to the main body in a short time, and also to ensure that the filter can be attached and detached smoothly. The purpose is to obtain a ceiling-embedded air conditioner that can.

(Means for Solving the Problems) The ceiling-embedded air conditioner according to the present invention has the following features: (1) A stepped portion is formed on the lower surface of the main body adjacent to the suction port, and a recess is formed by a partition plate and a drain pan. The decorative panel is provided with a plurality of guide side walls that engage with the stepped portion and the recess, and a dowel hole for fixing to the main body.

(2) A support shaft for rotatably attaching to the suction port of the decorative panel, a pair of fitting holes drilled on the edge facing the support shaft, and a pair of engagement holes provided near the support shaft. a filter having a suction grill having a suction grille, a fitting piece fitted into the fitting hole, a protrusion piece locked to the locking tongue, and a handle provided upright near the fitting piece. It was established.

(3) - The fitting piece in (2) above is gradually shortened toward the projecting corner of the filter.

[Effect]

The decorative panel according to the present invention can be positioned by temporarily fixing the fixing dowel six by fitting it into the mounting screw attached to the main body, and inserting the guide side wall into the step and recess of the main body.

On the other hand, the filter can be positioned by pushing it under the locking tongue of the suction grill, and by bending it, the fitting piece can be fitted into the fitting hole of the suction grill, making it easy to attach and remove it from the suction grill. It will be sure and smooth. Particularly, when the fitting piece is gradually shortened toward the projecting corner of the filter, attachment and detachment become more reliable and smooth.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 to 4, 522 is a partition plate to which the blower 2 is fixed. 23 is a heat exchanger, and a drain pan 24 made of a heat insulating material made of styrofoam is arranged below. Reference numeral 25 denotes a downward step portion of the main body 1, which is provided adjacent to the suction port 3. 26 is a recess formed by the partition plate 20 and the drain pan 24, and is provided between the Suita 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, and 29 is a decorative panel provided with a fixing plate 31 in which a plurality of fixing holes 30 are bored corresponding to the mounting screws 27 with washers 28. . Reference numeral 32 denotes a guide side wall, which is integrally formed with the decorative panel 29 so as to engage with the step portion 25 and the recess 26 and to come into contact with the air outlet 4 . 33
is a wind direction plate provided on the outlet grille 8. Note that the same or equivalent parts as in the conventional example are given the same reference numerals.

Next, the procedure for installing the main body l and the procedure for attaching the decorative panel 29 will be explained.

The ceiling-embedded air conditioner main body 1 is installed on a ceiling 21m using hanging bolts 5, and is installed so that the lower surface of the main body is exposed toward the room through an opening 20 in a ceiling 21.

The decorative panel 29 includes a washer 28 attached to the bottom surface of the main body 1.
The fixing holes 3o are fitted into the mounting screws 27 and temporarily fixed, and then the guide side molds 32 of the decorative panel 29 are inserted into the stepped portions 25. It is mounted to the main body 1 by positioning it in contact with the recess 26 and the air outlet 4, and tightening the mounting screw 27. The ceiling opening 20 is thus closed.

In FIG. 5, reference numeral 7 denotes a suction creel formed into a box shape with side edges 34 around the periphery, and is provided with a support shaft 35 for rotatably attaching it to the decorative panel 29. A pair of locking tongues 36 are provided inside the side edge 34 near the support shaft, and a pair of fitting holes 37 are provided in the side edge 34a facing the support shaft 35.

6 and 7, 13 is a filter, and the outer frame 1
4 and an inner intermediate frame 15, and a net 16 is integrally attached to the grid frame by welding or the like. 38 is a protrusion provided on both frame edges of the outer frame 14 so as to come into contact with the locking tongue 36 when the filter 13 is inserted into the locking tongue 36 F of the suction grille 7; The fitting pieces provided at both ends of one side are inserted and locked into the fitting hole 37 of the suction grille 7. Reference numeral 40 denotes a pair of handles, which are attached to the fitting pieces 3 of the outer frame 14.
9 and is integrally erected on the edge.

Next, the procedure for attaching and removing the filter will be explained.

First, one end of the suction grill 7 is removed from the decorative panel 29, and the suction grill 7 is rotated to be supported by the support shaft 35 at the other end.Then, the protrusion 38 side of the outer frame 14 of the filter 13 is engaged with the suction grill 7. Insert the projecting piece 38 under the tongue 36 to lock the tongue 36
The filter 13 itself is bent by applying further force, and the fitting piece 39 is inserted into the fitting hole 37 of the suction grille 7.
Fits in. In this way, the filter 13 is restored from its bent state and is smoothly attached to the suction grille 7.

For the filter 13 installed as described above, the handle 40 is pulled upward in the direction of its protrusion, as shown in FIG. The filter 13 is curved in the longitudinal direction. Then, the fitting piece 39 of the filter 13 comes off from the fitting hole 37 of the suction grille 7, and the filter 13 is removed from the suction grille 7.

FIG. 9 shows another embodiment of the pair of fitting pieces 39 described above. That is, the pair of fitting pieces 41 shown in FIG. 6 and FIG. 41a is provided. That is, the pair of fitting pieces 41 become gradually shorter toward the projecting corner 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 grille 7 smoothly.

〔Effect of the invention〕

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

In addition, the outer frame of the filter is integrally formed with a protruding piece and a fitting piece that engage with the locking base and the fitting hole provided on the suction grill, respectively, so that the filter has the protruding side attached to the locking base of the suction grill. By inserting the fitting piece under the suction grille, fitting the fitting piece into the fitting hole of the suction grille, and vice versa, it can be reliably and smoothly attached to and removed from the suction grille. In particular, when the fitting piece of the filter becomes shorter toward the projecting corner of the filter, the above-mentioned attachment and detachment becomes more reliable and smooth.
