Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air filter fixing device for an air conditioner that fixes an air filter attached to the air suction side of the air conditioner.

Generally, the air suction side and air blowing side of an air conditioner are
It is formed as shown in the figure.

That is, the front panel 2 is attached to the air conditioner main body 1,
An air suction port 3 is provided at the center of the front surface of the front panel 2, and an air outlet 4 is provided below the air suction port 3.

A vertically long groove 5 is provided inside the air suction port 3, and an air filter 6 is inserted into this groove 5 upward from a lower opening 7 and housed therein.

In order to fix the air filter 6 so that it would not fall out of the groove 5, conventionally, the front panel 2 and the air filter 6 were formed and fixed as shown in FIGS. 2 to 5.

To further explain, as shown in FIG.
Locking protrusions 8 and 9 are provided that protrude toward the inner and outer surfaces of.

One of the locking protrusions 9 protruding toward the inner surface of the air filter 6 is, for example, d=2Trr! A protrusion is formed by the length of rL.

On the other hand, at the lower part of the air filter 6, as shown in FIGS. 3 and 4, a retaining hook 10 is formed inside thereof and engages with the retaining protrusion 9 by riding on it from above. A triangular projection 11 for fitting into the opening 7 is formed on the outside thereof.

The engagement length C of the engagement hook 10 is set to cd, and the distance of the triangular protrusion 11 from the inner surface of the air filter 6 is b > a, for example, b = a + 2 mm.
It is formed to the size of.

FIG. 5 shows a state in which the air filter 6 shown in FIGS. 3 and 4 is inserted into the groove 5 and fixed, and as can be seen from the figure, the air filter 6 has the engaging hook 10 attached to the locking protrusion. At the same time, the triangular projection 11 is inserted into the opening 7 while elastically pressing forward the front edge 12 on which the locking projection 8 of the front panel 2 is formed. It is fixed by elastically holding the triangular projection 11 between the openings 7.

However, in this conventional device, since the force F that spreads outward is always acting on the front edge 12, the front edge 12 remains curled outward due to permanent distortion, and the opening size of the opening 7 is changed. It became b.

Since the engagement length between the locking protrusion 9 and the engagement hook 10 is approximately equal to b-a, the air filter 7 rattles due to the vibration of the air conditioner 1 due to the enlarged opening size. There was an inconvenience that it would fall out of the opening 7.

The present invention eliminates these disadvantages and provides an air filter fixing device for an air conditioner that can fix the air filter without falling off and also allows the air filter to be easily attached and detached. With the goal.

Examples 6 to 7 of the present invention will be described below.

In FIGS. 6 and 7, parts that are the same as those of the prior art are designated by the same reference numerals.

In the present invention, in place of the triangular protrusion 11 of the conventional example, an engaging hook 13 is formed on the outer surface of the air filter 6 to be engaged by riding on the engaging protrusion 8 formed on the panel 2 from above. be.

To explain further, if the protruding length b of the engagement hook 13 from the inner surface of the air filter 6 is b > a, then the engagement hook 13
A recess 14 into which the locking protrusion 8 is loosely inserted is formed at the lower part of the recess 14 .

The rest of the structure is the same as before. With this structure, when the air filter 6 is inserted through the opening 7, the two engaging hooks 13 and 10 elastically engage the two engaging protrusions 8 and 9 formed on the front panel 2. The air filter 6 is then fixed to the front panel 2, and the locking hooks 13 and 10 are respectively resting on the locking protrusions 8 and 9, and the air filter 6 is fixed to the front panel 2. Ru.

An engagement hook 13 formed on the outer surface of the air filter 6
Since no force is exerted outwardly on the locking protrusion 8 formed on the front panel 2, the front edge 12 is also prevented from being permanently strained outwardly.

Therefore, the air filter 6 is fixed without falling off due to the engagement between the two locking protrusions and the engaging hook.

Further, the air filter 6 is removed by holding its lower end and pulling it downward.

That is, when the air filter 6 is pulled down, each retaining hook 10, 13
The air filter main body is pulled out from the groove 5 by elastically riding over each of the locking protrusions 9 and 8 downward and pulling it further downward.

The air filter fixing device for an air conditioner of the present invention is structured so that the engaging hook is placed on the locking protrusion from above and locked and fixed, so the air filter will not fall off even after many years of use. It can be fixed securely, and the front edge of the front panel does not curl outward like in the past, so it does not spoil the aesthetics of the air conditioner. Moreover, the air filter can be installed and removed easily into the groove. It has the advantage that it can be easily carried out by engaging and disengaging it.
