Description

[Detailed Description of the Invention] This invention relates to an air conditioner incorporating a heat exchanger and a blower, and particularly to a fixing device for the side plate thereof.

A front view of a conventional air conditioner is shown in FIG. 1, details of section A in FIG. 1 are shown in FIG. 2, and a right side view of FIG. 2 is shown in FIG.

In each figure, 1 is the frame of the air conditioner body, 2
3 is a heat exchanger, 3 is a dew pan, 4 is a fan that generates wind, 5 is a motor that rotates fan 4, 6 is a fan 4 and a blower stand that attaches motor 5 to main body frame 1, and 7 to 9 are parts of frame 1. A folding piece 8a is formed on the front edge of the side panel 8, which is a panel that covers the top surface, both sides, and the front surface. Reference numeral 10 denotes a mounting plate formed in an L-shape, one side of which is spot welded.The other side of this mounting plate 10 is attached to the front edge of the side frame 1a of the frame 1 from the front side with mounting screws 11. Panel 8 is fixed to frame 1. 12 and 13 are a suction port and a blowout port, and 14 is a controller for controlling the motor 5 and the like.

In such a fixing device using the mounting plate 10, traces of spot welding remain on the mounting plate 10, which is unfavorable in appearance, and spot welding cannot be performed with PVC steel plates, etc., which are commonly used these days. Furthermore, ease of assembling also deteriorates. In addition to this method, as shown in FIG. 4, there is a method in which a screwed part 15 is integrally formed on the folded piece 8a of the side panel 8. This results in poor yield and increased costs.

This invention was made to eliminate the above-mentioned drawbacks, and one embodiment of this invention will be described below. That is, as shown in FIG. 5, a long hole 16 is formed in the folded piece 8a of the side panel 8 along its longitudinal direction.
At the same time, as shown in FIG. 6, a mounting piece 17 bent into an L-shape is provided. This mounting piece 17 is provided with a series of notches 18 spanning the bending ridge line A, with an insertion portion 19 formed in one piece and a fixing portion 20 formed in the other piece. A through hole 21 for insertion of the mounting screw 11 is formed in the fixing part 20, and overall, the length L ₁ of the insertion part 19 is equal to the length L ₂ of the fixing part 20.
It is formed to be longer by a predetermined length. In addition, since the length of the elongated hole 16 is set according to the size of the notch 18 and the lengths L ₁ and L ₂ of the insertion part 19 and the fixing part 20, the insertion part 19 of the mounting piece 17 can be made longer. hole 1
6, one piece thereof can be passed through the elongated hole 16 as shown in FIGS. 7 and 8, and can be locked to the back surface of the folded piece 8a. Therefore, in this state, the side panel 8 can be attached to the frame 1 by overlapping the front edge of the frame 1a on the side of the fixing part 20, inserting the mounting screw 11 into the through hole 21 of the fixing part 20 from the front side, and tightening it. .

Note that the notch 18 is located between the frame 1 and the side panel 8.
Depending on the positional relationship such as assembly accuracy with
There is no need to provide it across 0.

As described above, in this invention, one piece of the L-shaped mounting piece is inserted into the elongated hole, one piece is locked, and the other piece is screwed to attach the side panel to the side frame. The mounting piece can be manufactured separately from the side panel, the yield rate of plate cutting in press working is good, and there is no need for spot welding, so assembly is easy, and there are no restrictions on the materials that can be used due to spot welding.
