Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the shape of a mounting piece for attaching and detaching an electric box to and from a unit body, which is provided in an air conditioner, and its mounting structure.

[0002]

2. Description of the Related Art As described in Japanese Patent Application Laid-Open No. 4-236022, a conventional technique is to place a mounting piece of an electric box against a sliding piece of a mounting bracket and slide the sliding piece into a holding sliding hole of the mounting piece. A general method is to attach and detach the electric box by fitting and temporarily holding the moving holding portion.

[0003]

The conventional method for mounting an electric box of an air conditioner is such that, when the main body and the electric box are combined, the holding sliding portion provided on the holding piece has a holding sliding portion provided on the electric box. Due to the structure in which the holes are fitted together, when the electric box becomes large and the weight becomes heavy, its positioning becomes difficult, the assemblability is poor, and the work efficiency at the time of product assembly and service maintenance becomes poor. I have a problem.

An object of the present invention is to provide an electric box assembling structure in which the unit body and the electric box can be easily positioned and easily assembled even when the electric box is large and heavy, and there is no danger of dropping the electric box. To do.

[0005]

In order to achieve the above object, the present invention has a bent portion having a function as a rail for temporarily holding and sliding an electric box main body on both sides of a unit main body. Also, holding pieces having holes for positioning the temporarily held electric box are fixed to both sides of the unit body.

[0006] A mounting piece having a convex shape for fitting into a positioning hole is fixed to the outer shell of the electric box.

Further, the outer bottom plate of the electric box is provided with a notch for receiving the sliding portion of the holding piece.

[0008]

With this configuration, even if the electric box is large and heavy, when the electric box is assembled to the unit body, the electric box can be temporarily placed on the holding piece and temporarily held. Further, at this point, since there is no need for positioning, even a heavy electric box can be easily handled.

Since the bottom plate notch of the outer wall of the electric box is in contact with the sliding portion of the holding piece, when the electric box is assembled to the unit main body, the bent portion of the holding piece acts as a rail to easily make the electric box. Can be pushed into the unit, and the positioning hole provided in the holding piece and the convex mounting piece fixed to the outer wall of the electric box can be easily combined to determine the positions of the unit main body and the electric box.

After that, the unit body and the electric box are fastened with screws.

[0011]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 shows a schematic view of an electric box of an air conditioner, FIG. 2 shows a schematic view of a mounting piece 4 attached to the unit body side, and FIG. 3 shows details of mounting an electric box of an air conditioner. The figure is shown.

The description will be centered on FIG. A holding piece 4 having a holding piece sliding portion 5 for mounting the electric box and a positioning square hole 6 for inserting the mounting piece 2 having a convex shape is attached to the main body of the unit. A mounting piece 2 having a convex shape for positioning with the unit body is provided on the outer casing 1 of the electric box.
Attach. The cutout portion of the electric box bottom plate 3 having the cutout of the electric box outer casing 1 is put on the holding piece 4 so as to be engaged with the holding piece sliding portion 5 of the holding piece 4 and pushed inward as it is. This is because the notch of the electric box bottom plate 3 having the notch and the holding piece sliding part 5 have a relationship like a wheel and a rail, and the electric box can be easily pushed in once the electric box is placed. After the electric box is pushed in, the convex portion of the mounting piece 2 having a convex shape is inserted into the positioning square hole 6 of the holding piece 4.
This is effective for determining the mounting position of the electric box, and it is easy to match the screw holes for mounting the electric box and the unit body, and the electric box and the unit body can be easily fastened with screws.

Further, since the unit body rests on the sliding portion of the holding piece, it also prevents the unit body from dropping during the work of attaching / detaching the electric box at the time of service maintenance.

As described above, the holding piece 4 is provided on the unit body side.
By providing a mounting piece having a convex shape on the electric box side, work efficiency is improved and safety is also improved.

When fixing the electric box to the unit body, the electric box can be easily mounted by the structure in which the cutout portion of the outer bottom plate of the electric box and the sliding portion of the holding piece make contact with each other and the bent portion of the holding piece acts as a rail. It can be pushed inside the unit, and the convex mounting piece fixed to the outer shell of the electric box is combined with the positioning hole of the holding piece, the position of the electric box is determined, and the screw can be easily fastened. In addition, since the electric box is temporarily held by the holding piece even after removing the screw at the time of maintenance for removal, there is no risk of falling and it is safe and easy to handle even a heavy electric box. An electric box mounting device can be realized.

[0017]

According to the present invention, a heavy electric box can be placed and temporarily held on a holding piece. Therefore, both hands can be used freely for work, and work efficiency is improved.
