Description

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 has been used to attach a front frame of an air conditioner of this type. An example of the above-described conventional front frame mounting structure will be described below with reference to the drawings.

As shown in FIG. 7, in the conventional front frame mounting device, a cut-and-raised portion provided on the mounting member 3 is inserted into a holding portion 2e provided on the front frame 2 via a metallic mounting member 3.
It is configured such that the holding shape portion 5b provided on the fitting 3 is fitted to the holding portion 1e of the underframe 1 shown in FIG.

[0004]

However, in the above-mentioned configuration, the attachment 3 has a large variation in the cut-and-raised size, and the fitting force of the attachment 3 is too large to attach the attachment 3 to the front frame 2. Since the workability is very poor, or the workability is very small, the workability is remarkably impaired because a bond is applied to the attachments 3 and the holding portions of the front frame 2 because they are easily removed. Also, when attaching the front frame 2 to the underframe 1,
The heat exchanger attached to the
The heat exchanger may be damaged or the fixture 3 may not fit into the hole of the underframe 1, resulting in poor workability of attachment. Further, when trying to remove the front frame 2 from the underframe 1, it was very difficult to firmly remove the fitting between the underframe 1 and the fixture 3.

In view of the above-mentioned problems, the present invention improves the mountability of the mounting tool 3, and further significantly improves the mountability and dismountability of the front frame 2 to the underframe 1.
To provide a mounting structure.

[0006]

In order to solve the above-mentioned problems, the front frame mounting device of the present invention uses a synthetic resin as a mounting tool, and the mounting tool is provided with a flexible claw, and is provided at a position facing the claw. The mounting tool is fitted into the underframe having a hole having a holding shape for holding the claw, and the convex portion provided in the mounting tool and the hole provided in the front frame are fitted to each other, and the front frame and the underframe are provided. It is provided with a configuration in which and are attached via a fixture.

[0007]

According to the present invention, with the above-mentioned structure, the fitting force to the underframe does not change due to the dimensional variation of the mounting tool, and the fitting can be done with one touch, and the bond is fixed in consideration of the weak fitting force. However, it becomes possible to abolish this, and workability can be significantly improved. Also, by attaching the attachment to the underframe side, it is possible to prevent the attachment from damaging the heat exchanger.

Furthermore, when removing the front frame from the underframe,
By pressing the convex portion of the mounting tool, the mounting tool bends and can be easily removed.

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

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 structure in which a heat exchanger 4, a cross flow fan 7, and a power supply plate 5 are arranged on an underframe 1 and a front frame 2 to which a suction panel 8 is attached is attached. Further, in this embodiment, the pyroelectric sensor 6 is arranged 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 is The upper side of is fitted.

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 tool 3 as shown in the enlarged views of FIGS. The fixture 3 has a flexible claw 3a for attaching to the underframe 1, and when inserted into a hole 1a provided in the underframe 1, the claw 3a is fixed by being caught by a holding portion 1b provided in the underframe. You can 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 attachment 3 is attached to the attachment 3
This is to prevent the reverse insertion into the underframe 1.

The convex portion 3b provided on the attachment 3 is a rib for fitting with the hole 2a provided on the front frame 2, and the convex portion 3b is provided.
The underframe 1 and the front frame 2 can be fixed by fitting the holes 2a with each other. The convex portion 3b is provided with a C-plane cut 3e for facilitating insertion when the front frame 2 is attached. Further, as shown in FIG. 6, the fixture 3 and the front frame 2
The surface 3f contacting with is made into an undercut shape so that the fitting 3 and the front frame 2 are fitted together and cannot easily come off. Further, the rib 1d arranged on the underframe 1 prevents the weight of the front frame 2 from being directly applied to the attachment 3.

When the front frame 2 is to be detached from the underframe 1, it can be easily removed by pushing the attachment 3 in the direction of the arrow shown in FIG. 6 due to the characteristics of the synthetic resin of the attachment 3. Further, as shown in FIG. 2, even if a recess 2b is provided on the front side of the mounting hole 2a of the mounting tool 3 of the front frame 2, even if the air conditioner is installed at a position higher than a person's height, the position of the mounting tool 3 can be felt by hand. Is easy to understand.

[0014]

As described above, the present invention has a hole having a holding shape for holding a claw at a position opposite to a flexible claw provided on the fitting through the fitting made of synthetic resin. By adopting a configuration in which the underframe and the front frame provided with the hole for fitting the convex portion provided in the attachment are attached,
The fitting force between the front frame and the fitting does not change due to the dimensional variation of the fitting, and since the bond applied to the holding portion of the front frame can be eliminated, the workability of mounting the fitting can be significantly improved. Further, by adopting a structure in which the attachment is attached to the underframe, the attaching tool does not hit the heat exchanger and damage the heat exchanger when the front frame is attached to the underframe. And, when the front frame is attached to the underframe, it can be attached with one touch. Furthermore, 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 by both attachment and detachment.
