Description

[Detailed Description of the Invention] The present invention relates to an exterior plate assembly structure for an air conditioner.

Generally, when assembling the exterior panels of an air conditioner, a particular problem is the ventilation grille, which is weak in strength and tends to rattle.

For this reason, conventionally, the mounting frame for attaching the ventilation grill was formed into a rectangular shape using strong thick-walled sheet metal material, and this mounting frame was firmly attached to the main body with screws, but this increased the weight of the main body and made assembly difficult. Moreover, it had the disadvantage of high manufacturing cost.

In view of these points, the purpose of the present invention is to provide an air conditioner that has a mounting frame that is lightweight by minimizing the number of parts, is strong, and prevents rattling.

The structure of the present invention consists of a pair of decorative frames that support the ventilation grill, step pieces that are integrally formed with the frames and project sideways and have a substantially doglegged cross section with their front sides facing each other diagonally, and an inner wall and corner of the step pieces. The present invention is provided with a frame plate of the main body whose edges are in contact with each other, and a decorative cover which extends over both the step pieces and has an outer wall and an inner wall pressed against each other from the front and covers the frame plate. With such a configuration, the mounting frame can be formed of a pair of lightweight decorative frames, and the frame is given strength by being supported by the frame plate,
In addition, wobbling can be eliminated by press-fitting the decorative cover.

Below, an embodiment of the present invention will be explained based on the drawings.
Indoor air is sucked in from a suction grill (not shown) at the rear of the bottom of the housing and blown out from the grill 1 to the front.As shown in Fig. 2, the central sill 3 and the narrow sill 4 are made of synthetic resin. It has a rectangular shape.

Reference numeral 5 denotes sheet metal frame plates on both left and right sides that partition the main body 2 into the inside and outside and provide strength in the vertical direction.As shown in Fig. 3, they are screwed to the top plate 6 and screws 7, and to the bottom plate 8 and screws 9, respectively. .

Reference numerals 10a and 10b are a pair of upper and lower decorative frames made of sheet metal that support the ventilation grille 1, and the stepped pieces 11a and 11b, which are approximately dogleg-shaped in front and face each other diagonally, are integrally formed to project laterally. Top decorative frame 10
a is screwed to the top plate 6 with screws 12, and the lower decorative frame 10a is integrally formed with the bottom plate 8, and this inner wall 2
3a, 23b are corner edges 24a, 24 of the frame plate 5
It is in contact with b.

Reference numerals 13 and 13 denote decorative covers made of synthetic resin that are assembled on both the left and right sides of the main body 2, and as shown in FIGS.
The inner walls 15a, 15b are pressed from the front, and the locking portions 18a, 1 engage with the notch holes 17a, 17b of the upper and lower projecting pieces 16a, 16b of the frame plate 5.
8b and a groove 20 that presses into engagement with the protrusion 19 of the ventilation grille 1 are integrally formed.

Therefore, the top plate 6 and the bottom plate 8 are screwed together via the frame plate 5 to form the frame of the main body 2, and the top plate 6
A combination of three ventilation grilles 1 is inserted from the front between the upper decorative frame 10a screwed together, the lower decorative frame 10b integrated with the bottom plate 8, and the decorative cover 13 is shifted slightly forward from the main body 2. Locking parts 18a, 18
b into the notch holes 17a, 17b from the side, and then slide the decorative cover 13 backward along the main body 2, the inner walls 15a, 15b become the stepped pieces 11a, 1.
1b, the groove 20 engages with the protrusion 19, and the thick thread 3 and the thick threaded part 21 and the thin threaded part 4 and the thin threaded part 22 are connected to each other, and the decorative cover 13
At this point, the frame plate 5 is covered, and the assembly of the exterior plate is completed.

Since the present invention is configured as described above, the step pieces of the pair of decorative frames are clamped from the inside by the frame plate and from the outside by the decorative cover, so that they can be assembled and fixed in place in a strong state without wobbling. In addition, since the external impact force applied to the decorative frame is received by the frame plate, it can withstand the strength, and since no external force is applied to the ventilation grille, damage can be prevented.

Moreover, since a frame plate and a decorative cover are used, a pair of decorative frames, which are lighter than conventional rectangular mounting frames, is sufficient, and the main body can be made lighter and manufacturing costs can be reduced.

Furthermore, by using the decorative cover to attach the ventilation grille, screws for attachment are not required, and an air conditioner that is easy to assemble and has an excellent design can be obtained.
