By the way, since the indoor unit is usually installed at a high place, according to such a conventional structure, the protrusion of the air filter body is inserted into the insertion hole of the body frame of the air conditioner indoor unit. Work is difficult,
There was a problem that workability was poor. Also, since the elastic locking piece that is formed to maintain this engaged state is made by integral molding with resin of the same material as the air filter body, deterioration of the resin over time reduces the springiness. In addition to the insufficient fixing, there is a problem in that the spring property is changed even when the temperature changes. other than this,
Since the spring property is weak due to its structure, accidents such as the air filter coming off during transportation are likely to occur, and the effective area of the air filter is reduced by providing the elastic locking piece under it, reducing the filter capacity. There was also the problem of doing.

It is therefore an object of the present invention to provide an improved air filter mounting structure in an air conditioner indoor unit which overcomes the above mentioned problems in the prior art.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings.

1 and 2, reference numeral 1 is an air conditioner indoor unit main body, 2 is an air filter provided at an air intake port 1a of the air conditioner indoor unit main body 1, and the air filter 2 is a frame body portion 21 and a frame body portion. The filter portions 22 to 25 surrounded by 21 are integrally formed of a synthetic resin material having a comparatively good effect.

At the lower edge of the air intake port 1a of the air conditioner indoor unit body 1, two receiving grooves 11 and 12 for receiving the lower end edge 2a of the air filter 2 are formed integrally with the air conditioner indoor unit body 1. A metal for receiving the upper edge 2b of the air filter 2 and pressing the lower edge 2a of the air filter 2 into the receiving grooves 11 and 12 at the upper edge of the air intake port 1a of the air conditioner indoor unit body 1. Two leaf spring members 31 and 32 having flexibility are provided.

The leaf spring members 31 and 32 are both thin plates made of phosphor bronze or other metal having a good spring property and bent into the shape shown in FIG. 2, and are formed at the upper edge of the air intake port 1a. Therefore, they are attached to the receiving grooves 11 and 12 by fixing their bases to positions corresponding to the receiving grooves 11 and 12 by screwing or other appropriate known means.

Therefore, when the air filter 2 is attached to the air conditioner indoor unit main body 1, the air filter 2
A part of the upper edge 2b of the air filter 2 is pressed against the leaf spring members 31 and 32 and lifted upward against the spring force of the leaf spring members 31 and 32.
It is possible to get over the outer wall portions 11a and 12a of the first and the second portions 12 and drop the corresponding portions into the receiving grooves 11 and 12.
This state is the state shown in FIGS. 1 and 2, and in the air filter 2, the corresponding portions of the lower end edge 2a of the air filter 2 are firmly received by the receiving grooves 11 and 12 by the spring force of the leaf spring members 31 and 32. .

As can be seen from FIG. 2, the leaf spring members 31, 3 are
The front end portions 31a and 32a of the air filter 2 are bent so as to be slightly inclined toward the air filter 2
Since the upper edge 2b of the air filter 2 is received, the upper edge 2b of the air filter 2 is pushed inward of the air conditioner indoor unit body 1 and does not come off from the air conditioner indoor unit body 1. As a result, the air filter 2 is positioned so as to be substantially parallel to the intake side surface 4a of the heat exchanger 4 arranged near the air intake port 1a of the air conditioner indoor unit body 1. When the air filter 2 is removed, the air filter 2 is lifted upward against the spring force of the leaf spring members 31 and 32, and only the lower end edge 2a of the air filter 2 is taken out from the receiving grooves 11 and 12. Good.

According to the above construction, when mounting the air filter 2, the upper edge 2b thereof is pressed against the leaf spring members 31 and 32 and lifted upward to receive the lower edge 2a of the groove 11,1.
Since it is only necessary to put it in 2, there is no need for the troublesome work of inserting the protruding piece into the engagement hole as in the past.
Anyone can easily attach the air filter 2. This effect is particularly remarkable when the indoor unit is mounted at a high place.

Further, since the leaf spring members 31 and 32 are made of metal, they are excellent in durability, and their spring properties are not affected by temperature changes or deteriorated in a short period of time.
Further, since the spring property is strong, it is possible to reliably prevent an accident that the air filter 2 comes off during transportation.
Furthermore, since the air filter 2 is not required to have a special shape, it is possible to increase the area of the filter portion of the air filter 2 and improve its performance as compared with the conventional one.

In the embodiment described above, the lower end edge 2a of the air filter 2 is received by the receiving grooves 11 and 12, and the upper end edge 2b thereof is received by the leaf spring members 31 and 32.
Although the configuration is such that it is pushed down toward Nos. 1 and 12, this may be reversed. That is, the receiving grooves 11 and 12 may be provided at the upper edge of the air intake port 1a, and the leaf spring members 31 and 32 may be provided at the lower edge of the air intake port 1a.
