Description

[Detailed Description of the Invention] The present invention relates to an air conditioner having a vertically extending cabinet, such as a package type air conditioner.

Conventionally, in this type of air conditioner, left and right side plates constituting the outer box are fixed to a base material such as an angle.

However, if the side plates extend long in the vertical direction, there is a risk of partial distortion. Therefore, the side plates themselves should be thick enough to prevent distortion, or the base material should be extended in the vertical direction. The side plates were fixed to this base material so that the side plates could maintain a vertical plane. However, the former method has the disadvantages of poor workability, increased weight, and increased costs, while the latter method also has the drawbacks of increased work steps due to an increase in the number of bonding locations, and weight loss due to the use of a large amount of base material. This resulted in an increase in costs.

In order to eliminate these drawbacks, the present invention utilizes a front decorative frame, and by attaching this decorative frame, it prevents distortion of the side panels, reduces weight, and reduces work processes. One embodiment thereof will be described with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes an outer box of the air conditioner, which is composed of left and right side plates 2 (one of which is not shown), and a back plate 3 that connects these side plates 2. The front surface of the outer box 1 constitutes an inlet 4 and an outlet 5, and grills 6 and 7 are attached to them, respectively. A bent flange 8 bent at right angles is formed on the front side of the side plate 2, and an appropriate number of openings are opened outward (toward the side surface of the outer box) at appropriate locations on the bent flange 8, and these openings are closed. Elastic locking members 9, 9... having such elasticity are fixed by spot welding. Further, the bent flange 8,
The flange 10 connected to the back plate 3 is a base material necessary inside the main body 1, such as a base material 11 on which a blower (not shown) is placed, or a base material for fixing a heat exchanger (neither is shown). It is fixed with screws 12 at several locations.

In addition, the elastic locking members 9, 9 are appropriately provided at locations other than the locations where they are fixed to the base material 11. A front decorative frame 13 is attached to the front surface of the bending flange 8, and has the same length as the bending flange 8. The front decorative frame 13 includes a flange portion 13a which is in planar contact with the bent flange 8 and is inserted and locked from the opening side of the elastic locking devices 9, 9, and a side plate from the flange portion 13a. A front part 13b curved forward in an arc shape so as to be connected to the surface position of 2, a continuous part 13c bent at a right angle from the top of this arc-shaped front part 13b, and the flange at the edge of this continuous part 13c. The mounting portion 13d is horizontal with the portion 13a and is bent in the same direction. 14 is a heat insulating material located on the discharge port 5 side and filled in the front decorative frame 13, and 15 is a decorative board attached to the continuous portion 13c.

After the bent flange 8 of the side plate 2 is fixed to the base material 11, the front decorative frame 13 is fixed to the flange portion 13a.
is locked to the elastic locking tools 9, 9... and attached to the mounting portion 13d.
is fixed to the base material 11 with screws 16 to complete the assembly. At this time, distortions and the like are corrected by the flange portion 13a of the front decorative frame 13 in the portion other than the attachment point of the side plate 2 to the base material 11, and the flange portion 1
3a is connected to the arc-shaped front part 13b, so it does not deform and has sufficient strength even if it is formed from a thin plate material. Therefore, the front decorative frame 13 can be attached to only a few places, and the number of man-hours can be reduced.

In addition, the heat insulating material 1 provided in the front decorative frame 13
4 has better workability than, for example, inserting the part corresponding to the decorative frame into one that is formed integrally with the side plate. Furthermore, in terms of design, since the front portion 13b forms an arc shape continuous with the side plate 2, the effect is great without spoiling the appearance.

As is clear from the above description, the air conditioner of the present invention has bent flanges that extend vertically at the front of the left and right side panels of the outer box, and an appropriate number of places on the bent flanges that extend outward. A flange part that fixes the opening locking tool, and a flange part that is locked to the locking tool at one end and contacts the bending flange in a plane, and a circular arc shape that extends from the flange part to the surface position of the left and right side plates. A front decorative frame, which extends to approximately the same length as the bending flange, is attached, and the front decorative frame is made up of a front part that extends to the front part, and a mounting part that is screwed to the base material to which the left and right side plates are fixed at the other end. Therefore, the end faces of the side plate and the bending flange are prevented from being distorted by the flange part of the front decorative frame and the arc-shaped front part continuous to this flange part, so there is no need to use a separate angle, etc. In addition, the side plates can be thin, requiring fewer attachment points, and of course the number of attachment points for the decorative frame can also be reduced. Therefore, the overall weight can be reduced, the cost can be reduced, and the number of man-hours can be reduced.
