Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a side plate attachment device for an air conditioner, and its purpose is to provide a side plate attachment device that can easily and quickly fix the side plate.

In general, the shape and dimensions of a case such as an air conditioner are not constant, and the majority of cases are custom-made and have different shapes and dimensions depending on the manufacture.Moreover, in the case of a case that requires airtightness, the side wall to which it is attached Complicated machining is undesirable because it increases manufacturing costs, and for this reason, a method of maintaining airtightness is taken by using a large number of bolts. For example, as shown in FIG. 1, a housing forming a heat exchange chamber in an air conditioner has side walls fastened and fixed to a required frame with bolts. This case 1
A framework 2 having a desired shape is formed by an upper skeleton 3, a lower skeleton 4, a corner skeleton 5, a reinforcing skeleton 6, etc.,
A large number of side walls 7 and a top plate 8 are fixed to the frame 2 with a large number of bolts 9, and a heat exchanger, a humidifier, etc. (all not shown) are housed inside the frame 2 as a heat exchange chamber. A blower fan (not shown) is attached to the top or adjacent to it. Therefore, in this case, a large number of bolts 9 are required to maintain airtightness when attaching the side wall 7. Moreover, each skeleton 3
Even if screw holes and bolt through holes are pre-drilled in ~6, the side wall 7, and the top plate 8, the positions of the holes are often misaligned during installation, and the assembly requires time and effort to correct the hole positions. There is.

In view of these points, the present invention aims to reduce the number of man-hours required for installing the side wall, improve the airtightness of the mounting portion, and provide a good appearance. The present invention will be explained based on the embodiment shown in the drawings.

The drawing shows an example of a casing forming a heat exchange chamber in an air conditioner. The casing 1 has a framework 2 formed by an upper skeleton 3, a lower skeleton 4, a corner skeleton 5, and a reinforcing skeleton 6. A side wall 7 and a top plate 8 are attached to these skeletons, and the inside of this skeleton is used as a heat exchange chamber. The side wall 7 is made of a steel plate having a required size, its periphery is bent inward, and a heat insulating member 10 is attached to the inner surface of the side wall.

In order to easily attach this side wall 7 to the frame body 1, the four circumferences of a steel plate having a required size are bent inward to form an outer end piece 71, and the width of this outer end piece 71 is made to match the thickness of the heat insulating member 10. The end of the outer end piece is further bent, and the locking pieces 72 are connected so as to be approximately parallel to the side wall, and the side wall main body, the outer end piece 71, and the locking piece 72 form a cross-sectional shape around the four peripheries of the side wall. A groove in the shape of a square is provided, and the four peripheries of the heat insulating member are locked in this groove. A sponge or sponge-like extremely elastic member 11 is provided on the outer surface of the locking piece 72, and a magnet 12 is provided on the outer surface of this elastic member 11.
2 is fixed to the locking piece by adhesive or other method. Although it is desirable that the elastic member and magnet be provided over the entire length of the engaging piece, they may be provided only at necessary locations.

Bolt holes 73 are drilled at the four corners of the side wall formed in this way in order to securely attach the side wall to the frame body, and to facilitate alignment of the bolt holes drilled in the frame body and the side wall, respectively. , this bolt hole 73
A bolt 13 is screwed between the bolt hole drilled in the bone side and the bone body side, and the bolt 13 is integrally attached. The number of supplementary bolts to be fastened is four per side wall, which is an extremely small number compared to the conventional method, making bolt tightening easier, and magnets are installed between these bolts via elastic members. Then, this magnet is engaged and fixed to the skeleton side. As a result, the elastic member acts as an airtight packing, and even if the housing side is slightly distorted due to welding or the like, airtightness can be maintained.

The embodiment shown in FIG. 4 is a different embodiment in which the elastic member is omitted so that the same airtightness can be maintained and the side wall can be easily attached. In this embodiment, the locking piece 72 is bent at an angle slightly larger than 90 degrees with respect to the outer end piece 71, that is, at a certain obtuse angle θ, so that when the locking piece is attached to the frame, the leading edge of the locking piece is bent toward the frame side. Make it stand out a little. And on the outer surface of this locking piece, there is an elastic magnet that is longer than the length of the locking piece.
For example, the magnet sheet 12 is integrally provided by adhesion or other means, and the magnet 12 is shaped like a tongue so as to protrude longer than the tip of the locking piece 72, that is, the bag-shaped bent portion l of the side wall. The amount of protrusion of this magnet is assumed to be L. As a result, when the flexible magnetic sheet is attached to the frame of the side wall, even if the surface becomes uneven due to distortion of the frame, the magnetic sheet flexes and absorbs this distortion, and the bolt It can be installed in an airtight manner in conjunction with the fastening.
