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, a corner portion 6a is 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 heat exchanger detachably supported by the frame 8 and the support plate 10; the heat exchanger is led out from one of the frames 8; Inlet 9a and outlet 9b
has. 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. . 14 is a motor 15, a fan 16, and a mounting base 17
The blower is fixed to a pair of frames 8 via a mounting base 17. 18 is a filter, 1
9 is a suction port. When the blower 14 operates, the air sucked in from the suction port 19 passes through the filter 18.
The air flows through 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 an air conditioner configured in this way, in order to remove the side plate 5 during piping work, it is necessary to loosen the upper and lower screws that fix the side plate 5. In particular, the screws for fixing the side plate 5 after the piping work is completed are left in the gap. The space was narrow and extremely difficult.

This invention aims to provide an air conditioner with a structure in which the side plate can be easily fixed from the top with a single screw using a fastener.

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. First, the first and second top panels 201,
202 has a cavity 2 inside as shown in FIGS.
The first upper panel 201 has horizontal installation portions 205 and 206 formed by further bending one side end to form horizontal installation portions 205 and 03, 204. Fold back the end and then bend this end downward to attach the mounting part 2.
07, and a folded part 208 is formed by folding the end of this mounting part 207 upward.
In addition, a top flange 803, a bottom flange 804, which are formed by bending the peripheral edges of the pair of frames 8,
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 top flange 803 and fixed with screws, and the first and second top 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 of the connecting member 20 correspond to cavities 203 and 20 of the first and second upper panels 201 and 202.
4, and in this state, the connecting member 20
Horizontal installation parts 205, 20 of the first and second upper panels 201, 202 on the upper surface of the connecting part 2003 of
6 are installed, and both are connected by screw fixation to form the top panel 2. Also, the 9th ~
11 As shown in the figure, 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 by a mounting screw 22, and a protruding portion 2004 and a rising wall 2005 integral with the connecting portion 2003 are formed on the outer surface of the connecting portion 2003. A groove 2006 for accommodating a tongue piece is provided on the inner surface side of this rising wall 2005. on the other hand,
The side plate 5 is formed into a thin box shape by bending its peripheral edge. In addition, the bent portions 501, 502, 503
The upper folded part 504 has a stopper 21 and a groove 2006.
Tongue pieces 505 and 506 are formed at positions corresponding to the above, and a through hole 507 for inserting the stopper 21 is provided in the tongue piece 505. Connecting member 2 to side plate 5
0, loosen the mounting screw 22 and align the stopper 21 with the elongated hole 21 with this mounting screw 22 as the center.
01 so that it can freely move inward and outward directions, and if the tongue piece 506 of the side plate 5 is housed in the groove 2006, the installation position of the side plate 5 can be determined, and the stopper 21 can be placed in the through hole 507 of the tongue piece 505. The side plate 5 can be fixed in that position by inserting it into the position and tightening the mounting screws 22. Further, a pair of narrow rectangular square holes 508 are provided in the bent portion 502 at the bottom of the side plate 5. The base 7 has cold and hot water piping to the heat exchanger 9 and drain discharge piping (both not shown) inside.
It is formed in a U-shape so as to form an insertion space, and its both ends are fixed to the frame 8 with screws, and the upper surface of the base 7 has bent portions 701 and 702 formed on the front and rear surfaces. and side bending part 70
3, and the side surface bent portion 703 is further provided with a pair of cut and raised pieces 704 that are formed by cutting upwardly between cuts of different lengths cut from the edge of the side bending portion 703 and facing in opposite directions. It is being Also, this cut and raised piece 7
04 is set to be approximately equal to the diagonal length of the square hole 508 at the bent portion of the bottom surface of the side plate 5. Therefore, when assembling the side plate 5, insert the square hole 508 at the bent portion of the bottom of the side plate 5 into the cut-and-raised piece 704 of the base 7, and loosen the mounting screw 22 on the upper side of the side plate 5. 22, the stopper 21 can freely move inward and outward through the elongated hole 2101, and with the tongue piece 5006 of the side plate 5 positioned above the groove 2006, the square hole 508 is inserted into the cut and raised piece 704. Then the tongue piece 5006 becomes the groove 2006
The mounting position of the side plate 5 can be determined. Then, by inserting the stopper 21 into the through hole 507 and tightening the mounting screw 22, the side plate 5 is fixed in that position.

As described above, in this invention, the side plate can be removed very easily by inserting the cut and raised piece of the base into the square hole at the bottom of the side plate and fixing the top of the side plate with a single screw using a stopper.
