The present invention relates to a structure for assembling an air conditioner indoor unit rear plate, and more particularly, to a structure for fitting the indoor unit rear iron plate to the indoor unit rear plastic injection molding of the wall-mounted air conditioner at four points.

The parts of the air conditioner indoor unit are embedded in a plastic injection molding, and then the steel sheet is fixed to the wall after the plastic injection molding is fixed to the iron plate. According to the prior art, the plastic injection molding and the iron plate are bolted at a plurality of points (generally four points). Fixing bolts at multiple points takes time when installing the indoor unit of the air conditioner and is cumbersome and requires bolts to be fixed. In addition, it is impossible to fix the iron plate on the wall first and install the indoor unit on the iron plate.

In order to solve the above problems, an object of the present invention is to provide a structure for assembling the indoor unit rear iron plate of the wall-mounted air conditioner to the plastic injection molding of the indoor unit by fitting at four points. By fitting them together, they can be assembled quickly and easily, and no separate parts are required for assembly. In addition, it is also possible to install the indoor unit by assembling the rear plastic plate of the indoor unit on the wall first and then assembling the plastic injection molding of the rear unit of the indoor unit on the rear plate of the indoor unit.

In order to achieve the above object, the present invention provides a structure for assembling the indoor unit rear plate on the outside of the indoor unit rear plastic injection molding of the air conditioner,

The indoor unit rear iron plate includes: two first protrusions each having a first protrusion body extending upward from an upper end of the indoor unit rear iron plate and a first protrusion protrusion extending forward from an end of the first protrusion body; And two second protrusions each having a second protrusion body extending forward from both side ends of the indoor unit rear iron plate and a second protrusion protrusion extending upward from an end of the second protrusion body.

The indoor unit rear plastic injection molding includes two joining grooves formed so that, when the indoor unit rear steel sheet is joined to the indoor unit rear plastic injection molding, the first protrusion can be inserted into a position corresponding to the upper protrusion; And two third protrusions formed at positions that can be fitted between the main body of the indoor unit rear plate and the second protrusion protrusion when the indoor unit rear plate is coupled to the indoor unit rear plastic injection molding. Provide a structure for assembly.

The depth of the engagement groove is preferably equal to the length of the first protrusion body.

Preferably, the length of the first protrusion body is longer than the length of the second protrusion protrusion.

The first protrusion and the second protrusion may be press molded integrally with the indoor unit rear iron plate, and the third protrusion may be injection molded integrally with the indoor unit rear plastic injection molding.

Hereinafter, with reference to the drawings will be described in more detail the structure of the present invention.

A perspective view from below of a portion of the plastic injection molding 20 of FIG. 1 to illustrate in detail.

The indoor unit rear plate 10 has two first protrusions 12 at the top, two second protrusions 14 at each side, and a nail insertion hole 16 into which nails are inserted on a vertical center line. Has

The first protrusion 12 is the first protrusion body 12a extending upwardly from the upper end of the indoor unit rear iron plate 10 and the front of the first protrusion body 12a (the indoor unit rear plastic injection molding 20 in FIG. 1). Direction) and the first projections 12b extending in the other direction.

The second protrusion 14 is a second protrusion body 14a extending forward from the side end of the indoor unit rear plate 10 and a second protrusion protrusion 14b extending upward from the end of the second protrusion body 14a. It is composed.

The indoor unit rear iron plate 10 may be manufactured by pressing from one iron plate, and the first protrusion 12 and the second protrusion 14 may be manufactured integrally with the indoor unit rear iron plate 10.

The indoor unit rear plastic injection molding 20 has two coupling grooves 22 at the top, and two third protrusions 24, one at each side.

The coupling groove 22 is equal to the width of the first protrusion 12 at a position corresponding to the first protrusion 12 so that the first protrusion 12 of the indoor unit rear plate 10 can be inserted upward. It is formed with a wide width. The depth of the engaging groove 22 is equal to or greater than the length of the body 12a of the first protrusion 12. After the assembly of the indoor unit rear plate 10 and the indoor unit rear plastic injection molding 20 is completed, a portion of the load of the indoor unit is transferred to the indoor unit rear plate 10 through the first protrusion 12. The depth is preferably equal to the length of the first protrusion body 12a.

In order to be able to engage with the second protrusion 14 of the indoor unit rear plate 10, the third protrusion 24 is the body of the indoor unit rear plate 10 and the second protrusion projections at a position corresponding to the second protrusion 14 ( 14b) protrude inward with a thickness equal to or less than the gap between them.

Hereinafter, a process of assembling using the present invention having the above-described configuration with reference to the drawings to be described in more detail.

3 is a perspective view showing the state in the first stage of the air conditioner indoor unit rear assembly, and FIGS. 4A and 4B are the engagement state of the first protrusion 12 and the engaging groove 22 and the second protrusion 14 in the first stage, respectively. ) Is a cross-sectional view showing a coupling state of the third protrusion 24.

In the first stage of assembly, the upper end of the first projection 12 of the indoor unit rear plate 10 is inserted into the coupling groove 22 of the indoor unit rear plastic injection molding 20 and the first projection 12b is inserted into the coupling groove ( 22) After the jaw 26 of the inlet is over, the indoor unit rear plate 10 is rotated by rotating the indoor unit rear plate 10 with the axis of the first protrusion projection 12b spanned by the jaw 26. ).

3 is a perspective view in a state where the first step is completed. At this time, the indoor unit rear iron plate 10 is bent downward by the length of the first protrusion body 12a from the final position of the assembly.

FIG. 4A shows in detail the state of the first protrusion 12 and the engaging groove 22 in FIG. 3. The first protrusion projection 12b is in a state spanning the jaw 26 at the entrance of the engaging groove 22.
