DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front frame mounting device for an air conditioner.

[0002]

2. Description of the Related Art Conventionally, a metal leaf spring is used for mounting a front frame of this type of air conditioner. Hereinafter, an example of the above-described conventional front frame mounting structure will be described with reference to the drawings.

[0003] As shown in FIG. 7, in the conventional front frame mounting device, a cut-and-raised portion provided on the mounting device 3 is attached to a holding portion 2 e provided on the front frame 2 via a metal mounting device 3.
In this configuration, the holding shape portion 5b provided on the attachment 3 is held by the holding portion 1e of the underframe 1 shown in FIG.

[0004]

However, in the above configuration, the size of the cut-and-raised mounting fixture 3 varies greatly, and the fitting force of the mounting fixture 3 is too large to attach the mounting fixture 3 to the front frame 2. Since the workability is extremely poor or too small, the workability is significantly impaired because a bond is applied to the attachment 3 and the holding portion of the front frame 2. When attaching the front frame 2 to the underframe 1, the underframe 1
The heat exchanger attached to the
In some cases, the heat exchanger may be damaged, or the mounting fixture 3 may not enter the hole of the underframe 1 properly, resulting in poor mounting workability. Further, when trying to remove the front frame 2 from the underframe 1, it is very difficult to firmly remove the underframe 1 and the attachment 3 from each other.

[0005] In view of the above problems, the present invention has improved the mountability of the mounting fixture 3 and further improved the mountability of the front frame 2 to the underframe 1 and the removability.
An object of the present invention is to provide a mounting structure.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a front frame mounting apparatus according to the present invention uses a synthetic resin as a mounting tool, and has a flexible claw provided on the mounting tool. A fitting is fitted to an underframe having a hole having a holding shape for holding the claw, and a protrusion provided on the fitting and a hole provided in the front frame are fitted to each other to form a front frame and an underframe. Are attached via a fixture.

[0007]

According to the present invention, it is possible to perform one-touch fitting with the above structure without changing the fitting force to the underframe due to dimensional variation of the mounting tool, and furthermore, taking into account the case where the fitting force is weak, the bond fixing is performed. However, this can be abolished, and workability can be significantly improved. In addition, since the attachment is attached to the underframe, it is possible to prevent the attachment from damaging the heat exchanger.

Furthermore, when removing the front frame from the underframe,
By pressing the projection of the attachment, the attachment can be flexed and easily removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A front frame mounting apparatus according to one embodiment of the present invention will be described with reference to the drawings.

FIGS. 3 and 4 are a side view and a partially enlarged view of an air conditioner according to an embodiment of the present invention. The air conditioner has a configuration in which a heat exchanger 4, a cross flow fan 7, and a power supply plate 5 are arranged on a frame 1, and a front frame 2 to which a suction panel 8 is mounted is mounted. Further, in the case of the present embodiment, the pyroelectric sensor 6 is disposed on the power supply plate 5, and when the front frame 2 is attached to the underframe 1, after fitting the hole 2c on the lower side of the front frame 2, the front frame 2 Are fitted on the upper side.

In the front frame mounting apparatus of the present invention, the underframe 1 and the front frame 2 are mounted via a synthetic resin mounting member 3 as shown in the enlarged views of FIGS. The attachment 3 has a flexible claw 3a for attaching to the underframe 1. When inserted into the hole 1a provided in the underframe 1, the claw 3a is hooked and fixed to the holding portion 1b provided on the underframe. I can do it. The stepped portion 3c of the attachment 3 hits the portion 1c of the underframe 1 when the attachment 3 is inserted into the underframe 1, and serves as a stopper. Further, the rib 3d provided on the fixture 3 is
Is prevented from being reversely inserted into the underframe 1.

The convex portion 3b provided on the attachment 3 is a rib for fitting into the hole 2a provided on the front frame 2, and the convex portion 3b
The underframe 1 and the front frame 2 can be fixed by fitting the hole 2a with the underframe 1. The projection 3b is provided with a C-plane cut 3e to facilitate insertion when the front frame 2 is attached. Also, as shown in FIG.
3f is in an undercut shape so that the fitting 3 and the front frame 2 are not easily detached in a fitted state. Further, the ribs 1d provided on the underframe 1 prevent the weight of the front frame 2 from directly applying to the fixture 3.

When the front frame 2 is to be removed from the underframe 1, the attachment 3 is pushed in the direction of the arrow shown in FIG. Further, as shown in FIG. 2, even when the air conditioner is installed at a position higher than a person's back by providing a concave portion 2b in front of the mounting hole 2a of the mounting device 3 of the front frame 2, the position of the mounting device 3 can be felt. Is easily understood.

[0014]

As described above, the present invention has a hole provided with a holding shape for holding a nail at a position opposed to a flexible nail provided on the mounting tool via a mounting tool made of synthetic resin. By mounting the underframe and the front frame provided with a hole for fitting the protrusion provided on the mounting tool,
The fitting force between the front frame and the fixture does not change due to the dimensional variation of the fixture, and the workability of attaching the fixture can be significantly improved by eliminating the bond applied to the holding portion of the front frame. Further, by adopting a structure in which the attachment is attached to the underframe, when the front frame is attached to the underframe, the attachment does not hit the heat exchanger and does not damage the heat exchanger. And when attaching the front frame to the underframe, it became possible to attach it with one touch. Furthermore, even when trying to remove the front frame from the underframe, it is possible to easily remove it by pressing the mounting tool,
Workability can be remarkably improved in both attachment and detachment.
