Description

[Detailed Description of the Invention] This invention relates to a mounting structure for an exterior panel of an air conditioner.

A conventional air conditioner was constructed as shown in FIGS. 1 to 4. In other words, 1 is the main body, 2 is the top panel, 3 is the outlet grille, and 4a and 4b are the end covers and electrical panel covers provided on both sides of the outlet grille 3, including the outlet grille 3, the end cover 4a, and the electrical panel cover 4b. The top panel 2 is fitted into a hole punched and drawn. 2a, the corners of the upper panel 2 are finished by welding for design purposes. 5 is a side plate, 6 is a front panel, and like the top panel 2, corner portions 6a are finished by welding. Reference numeral 7 denotes a base, which forms the external appearance of the air conditioner main body 1 together with the above-mentioned elements 2 to 6.

8 is a pair of frames forming an air passage communicating with the blowout grille 3 in the main body 1; 9 is a frame 8;
A heat exchanger is detachably supported by a support plate 10 and an inlet 9 led out from one frame 8.
a and an outlet 9b. A drain pan 11 is removably inserted and supported in a notch 8a formed in a substantially U-shape in the frame 8 below the heat exchanger 9, and has a discharge port 12 and a discharge pipe 13 outside one frame 8. .

Reference numeral 14 denotes a blower consisting of a motor 15, a fan 16, and a mounting base 17, which is fixed to a pair of frames 8 via the mounting base 17. 18 is a filter, 19
is the suction port. When the blower 14 is operated, the air sucked through the suction port 19 flows through the filter 18 to the heat exchanger 9, where it becomes cold air or hot air and is blown out from the blow-off grille 3.

Next, the assembly structure of each element will be explained. Fourth
As shown in the figure, screws 30 are attached to the top panel 2 and base 7.
The top panel 2 is fixed to the frame 8 with the screws 30 and nuts 31, and the side plate 5 is fixed to the top panel 2 and the base 7 with the screws 30 and nuts 31.

In air conditioners configured in this manner, if the width dimension changes depending on the model, the bending of the end face of the top panel and the drawing hole size of the outlet grille will change, so a mold corresponding to the model is required.

This invention was developed in consideration of the above-mentioned circumstances, and aims to provide an air conditioner that can be used with different models simply by changing the length of the top panel.

An embodiment of this invention will be described below.
That is, in FIG. 5, 201 and 202 are first and second upper panels that are parallel to each other at a predetermined interval, and 3 is the first and second upper panel 201 and 20.
2, 4a and 4b are end covers and electrical panel covers provided on both sides of the outlet grill 3, 5 is a side plate, 6 is a front panel, and 7 is a base, each of the above elements. Together, they form the external appearance of the air conditioner main body 1. In FIGS. 6 and 7, 8 is a pair of frames forming an air passage communicating with the outlet grille 3 in the main body 1, and 9 is a pair of frames 8.
The heat exchanger is detachably inserted and supported in a square hole 801 formed in the frame 8, and has an inlet 9a and an outlet 9b led out from one frame 8. 11 is a through hole 80 formed in a substantially V-shape below the square hole 801.
A drain pan 2 is removably inserted into and supported by the frame 2, and a drain port 12 is provided at the end led out from one frame 8.
has. Other structures are the same as the conventional example.

Next, the assembly structure of each element will be explained in more detail.

7 and a folded part 208 is formed by folding the end of this mounting part 207 upward.

Additionally, a top flange 803 and a bottom flange 80 are formed by bending the peripheral edges of the pair of frames 8.
4. Front and rear flanges 805 and 806 are formed,
A flange 807 is formed by cutting and bending at the upper corner of the front side, and a notch 808 is formed at the upper part of the rear side. The first top panel 201 has a mounting portion 2
07 to the flange 807 of the frame 8, and the horizontal installation part 205 to the top flange 803, respectively, and are fixed with screws. In addition, the folded portion 209 of the second top panel 202 is inserted into the notch 808 of the frame 8, and the horizontal installation portion 20
6 is in contact with the upper surface flange 803 and fixed with screws, and the first and second upper surface panels 20
1 and 202 are assembled in parallel with each other at a predetermined interval.

Reference numeral 20 shown in FIG. 9 is a connecting member made of aluminum die-casting or synthetic resin, and protrusions 2001 and 2002 formed at both ends are the first and second connecting members.
Cavities 203, 204 in top panels 201, 202
In this state, the horizontal installation portions 205, 206 of the first and second upper panels 201, 202 are placed on the upper surface of the connecting portion 2003 of the connecting member 20.
are installed, and the two are connected by screws to form the top panel 2. Also, 9th to 1st
As shown in FIG. 1, the connecting portion 2003 of the connecting member 20
A stopper 21 having an elongated hole 2101 in the center is attached to the top surface with a mounting screw 22, and a protruding portion 2004 and a rising wall 2005 integral with the connecting portion 2003 are provided on the outer surface of the connecting portion 2003. A groove 2006 for accommodating the tongue piece is provided on the inner surface side of the rising wall 205.

On the other hand, the peripheral edge of the side plate 5 is bent by drawing. In addition, the bent portions 501, 50
2,503 is further folded back, and the upper folded part 504 has tongue pieces 505, 506 at positions corresponding to the stopper 21 and the groove 2006.
The tongue piece 505 is further provided with a through hole 507 for inserting the stopper 21. When attaching the side plate 5 to the connecting member 20, loosen the attaching screw 22 and insert the stopper 21 around the attaching screw 22.
