FIG. 3 is an exploded cross-sectional view of a ceiling-embedded air conditioner according to the present invention, FIG. 4 is a cross-sectional view of a main part of the ceiling-embedded air conditioner according to the present invention, and FIG. FIG. 5B shows a state where the panel is lowered from the panel frame body, FIG. 5B shows a state where the panel is attached to the panel frame body, and FIG. 5 is an exploded perspective view of the main part of the ceiling-embedded air conditioner according to the present invention.
[0013]
As shown in the figure, 1 is a case body of a ceiling-embedded air conditioner, 5 is a blower provided in the center of the case body 1, 7 is a bell mouth provided on the lower suction side of the blower 5, 6 is a heat exchanger disposed around and having a drain pan a at the lower portion, 1a is formed between the drain pan a and the lower end of the case body 1, and the heat exchanged by the heat exchanger 6 A panel frame body 4 provided with a delivery section for delivery and attached to the opening on the bottom side of the case body 1 is provided with a suction grille constituting a suction port 2 communicating with the bell mouth 7, and the delivery is provided around it. The decorative claw B provided on the decorative panel 4 is detachably engaged with the engaging part A provided on the panel frame 1a. It becomes the composition which was made.
[0014]
Next, in the ceiling-embedded air conditioner having the above-described configuration, the hanging hook 8 that suspends and supports the decorative panel 4 so as to be movable up and down is used as a fastening member as in the related art described above. A structure that can be easily and accurately attached without any trouble will be described.
One end of the plurality of hanging hooks 8 is attached with a screw D to a mounting portion C to which one end of a plurality of hanging hooks 8 formed of a hook portion 8a formed in a substantially L shape is provided on the decorative panel 4. This is suspended in a vertically movable manner, and is engaged with an insertion portion 9 for removably inserting the other end of the suspension hook 8 into the panel frame 1a, and a locking hole 8b provided at the other end. The hook portion 8 a provided at one end of the plurality of hanging hooks 8 is attached to the attachment portion C of the decorative panel 4. On the other hand, the other end of the suspension hook 8 is inserted from the insertion portion 9, and the engagement portion 10 is engaged with an engagement hole 8b provided at the other end so that the decorative panel 4 can be moved up and down. It becomes a structure that can be suspended and supported.
[0015]
In addition, the mounting portion C of the decorative panel 4 is composed of a sheet metal reinforcing member for reinforcing the decorative panel 4, whereby the strength of the decorative panel 4 can be reinforced and The panel 4 can be firmly suspended and supported.
[0016]
The insertion portion 9 includes a substantially rectangular insertion hole 9 corresponding to the plate-shaped suspension hook 8, and the locking portion 10 includes a protruding locking piece 10 on one side of the insertion hole 9. Part 10 is provided,
As a result, the other end of the suspension hook 8 provided with the locking hole 8b locked to the locking portion 10 may be easily separated by being regulated by the other side of the insertion hole 9. The structure is such that it does not exist.
[0017]
Further, on the other side of the insertion hole 9, a protruding regulation piece 11 that regulates both sides of the suspension hook 8 that is locked to the locking piece 10 is provided.
As a result, the suspension hook 8 can be effectively regulated on both sides so as not to be displaced.
[0018]
Further, the locking piece 10 is provided in a slightly higher position with respect to the restricting piece 11, so that when one end of the suspension hook 8 is removed from the attachment portion C, FIG. As shown, the suspension hook 8 is inclined so that it can be inserted into and removed from the locking piece 10.
[0019]
Further, the distal end portions of the locking piece 10 and the restricting piece 11 are formed so as to overlap vertically when viewed from the side, like the overlap portion b shown in FIGS. 2 (B) and 3. Thus, as described above, the hooking hook 8 can be inserted into and removed from the locking piece 10 only by inclining the hanging hook 8 at a predetermined angle.
[0020]
Further, since the locking piece 10 and the restriction piece 11 are formed integrally with the panel frame 1a, the dimensional shape can be accurately finished and the structure is advantageous in terms of cost. .
[0021]
With the above configuration, as shown in FIG. 1, FIG. 2 (A) and FIG. 2 (B), FIG. 3, FIG. 4 (A), FIG. 4 (B), and FIG. One end of the plurality of suspension hooks 8 is attached to the attachment portion C of 4 and is suspended so as to be movable up and down, and the other end of the suspension hook 8 is removably inserted into the panel frame 1a. Since the insertion portion 9 to be engaged and the engagement portion 10 to be removably engaged with the engagement hole 8b provided at the other end are provided, the plurality of suspension hooks 8 are attached to the attachment portion C of the decorative panel 4. The other end of the suspension hook 8 is inserted from the insertion portion 9, and the locking portion 10 is locked in a locking hole 8b provided at the other end. The ceiling-embedded air conditioner can be hung and supported so that it can be lifted and lowered.
[0022]
