DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a specific embodiment of the ceiling-mounted air conditioner of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of the present invention,
It is an exploded perspective view of a ceiling embedded type air conditioner.

In FIG. 1, reference numeral 1 denotes a metal casing embedded in a ceiling surface, which is formed in a box shape opened on the lower side. Reference numeral 2 denotes a plate-like partition member attached to the inside of the casing 1. The partition member 2 has an upper end attached to the top surface of the casing 1 and both side ends attached to side surfaces of the casing 1, respectively. 2 and casing 1
This divides the internal space of the casing 1 into a suction side space 3 and a discharge side space 4. A blower (not shown) such as a sirocco fan is provided in the suction side space 3, a heat exchanger (not shown) is provided in the blowout side space 4, and a drain pan 5 is provided below the heat exchanger. Has been established. On the other hand, reference numeral 11 denotes a lower surface panel made of resin which is attached to a lower side of the casing 1. The lower surface panel 11 has an inlet 12 and an outlet so as to communicate with the suction side space 3 and the discharge side space 4 of the casing 1, respectively. 13 is open. The lower surface of the lower panel 11 has a shallow recess formed around the suction port 12, and a suction grill (not shown) having a large number of slits is detachably attached to the recess 11a. With the configuration described above, the air sucked into the suction side space 3 from the suction port 12 by the blower exchanges heat with the heat exchanger in the blowout side space 4 and blows out from the blowout port 13 into the room.

As shown in FIGS. 1 and 2, a temporary fixing hook 14, 14 stands up from the edge of the suction port 12 at substantially the center of the upper surface of the lower panel 11, and at least the tip of the hook 14 extends downward from the suction port. 12 and can be visually recognized. The hooks 14 are integrally formed with the lower panel 11. On the other hand, in the casing 1,
Reinforcing edge 2a bent horizontally from the lower end of partition member 2
, The temporary fixing holes 1, 14
5 and 15 are formed. The reinforcing edge 2 a is provided to improve the rigidity of the partition member 2. The tip of the temporary fixing hook 14 is cut obliquely on both sides to form cut portions 14a, 14a, whereby the tip is tapered downward. 16 are fixing screws for finally attaching the lower panel 11 to the casing 1, and 17 is a blind cover for hiding the fixing screws.

In the ceiling-mounted type air conditioner having the above structure, the lower panel 11 with the suction grille removed is lifted with respect to the casing 1 embedded in the ceiling surface, and the temporary fixing hooks 14, 14 are temporarily fixed on the casing side. When the hooks are hooked on the stopper holes 15, 15, the temporary fixing is completed. Also, with the suction grille removed, the temporarily fixed lower surface panel 11 is slightly lifted and shifted to the side so that the temporarily fixed hooks 14 and 14 are temporarily fixed holes 1.
5 and 15, the lower panel 11 is removed. Meanwhile, the temporary fixing hooks 14, 14 and the temporary fixing holes 15, 15
Can be visually recognized from below through the suction port 12, so that the lower panel 11 can be temporarily fixed to the casing 1 with good workability.

Further, since the temporary fixing hooks 14 and 14 are integrally formed with the lower panel 11, the conventional leaf spring 53 becomes unnecessary, and the existing partition member 2 is used for forming the temporary fixing holes 15 and 15. In addition, a new member is not required, and the cost can be reduced by reducing the number of parts. Moreover, since the temporary fixing holes 15, 15 are formed in the reinforcing edge 2a of the partition member 2, the temporary fixing hooks 14, 14 hit the partition member 2 and are guided in the lateral direction when temporarily fixing.
Temporary fixing can be performed with better workability. Further, cut portions 14a, 14a are formed at the tips of the temporary fixing hooks 14 and tapered downward, so that the temporary fixing hooks 14, 1 are formed.
When the hook 4 is hooked on the temporary fixing holes 15, the lateral displacement is absorbed, so that the temporary fixing can be performed with further improved workability.

In the above embodiment, two temporary fixing hooks and two temporary fixing holes are provided, but the number is arbitrary.

[0019]

As described above, in the ceiling-embedded air conditioner of the first aspect, it is possible to visually recognize that the temporary fixing hook is hooked on the temporary fixing hole by using the suction port of the lower panel. Compared with the conventional temporary fixing structure using the daruma hole and the leaf spring, the lower panel can be temporarily fixed to the casing with good workability.

Further, according to the present invention, the cost can be reduced by reducing the number of parts.

Further, according to the third aspect, the function of guiding the temporary fixing hook can perform the temporary fixing with higher workability.

Further, according to the present invention, since the lateral displacement between the temporary fixing hook and the temporary fixing hole can be tolerated, the temporary fixing can be performed with further improved workability.
