[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention relates to an air conditioner, and more particularly to an air filter device.

[0002]

2. Description of the Related Art FIG. 5 is a cross-sectional view showing a conventional filter fixing device disclosed in, for example, Japanese Patent Laid-Open No. 2-136630, in which reference numeral 1 is an air conditioner body, which includes a heat exchanger 2 and a blower 3. Built-in. 4 is a front panel, 5 is a suction port for sucking air, 6 is an air filter provided between the front panel 4 and the heat exchanger 2, and a fixing projection 7 is integrally formed. Reference numeral 8 is a rail for inserting and fixing the air filter 6, and 9 is a charging filter, which is provided on the back surface of the air filter 6 by a mounting guide 10. 11 is a stepped hole provided in the air filter 6, 12 is a mounting hole provided in the charging filter 9, 13 is an engaging claw provided in the mounting guide 10, and the stepped hole 11 in the air filter 6 is Engages and fixes the charging filter 9 to the air filter 6.

Next, the operation will be described. The air filter 6 to which the charging filter 9 is attached is guided and inserted along the rail 8 and fixed to the front panel 4 by the projection 7.

[0004]

Since the conventional filter device is constructed as described above, when a latch is used to fix the air filter, the latch hits when the filter is attached or detached. When the depth of the air conditioner body becomes thicker and the suction port is provided on the ceiling surface of the body, it is necessary to bend and insert the air filter, which makes it difficult to bend and remove it. was there.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to reduce the depth of the air filter even if a latch is used for fixing the air filter, and to provide an apparatus for bending and inserting the air filter to fix the air filter. The purpose is to get.

[0006]

A filter device for an air conditioner according to the present invention comprises a frame body provided with a bendable thin portion,
In addition, an air filter provided with a fixing latch, a plurality of charging filters provided above the thin portion of the air filter, and a charging filter fixing tool including a frame body connected in series by a connecting plate are provided.

[0007]

In the filter device according to the present invention, when the air filter is inserted, the frame of the air filter is bent at a portion where the charging filter is not fixed, and the charging filter is inserted by escaping the latch.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, 14 is a ceiling suction port provided on the ceiling surface of the front panel 4, 15 is a guide rib, and 16 is a mounting boss, which is integrally provided on the front panel 4.
Reference numeral 17 denotes a frame body of the air filter 6, which is provided with a thin portion 18 which is bendable and deformable at an upper portion thereof. Reference numeral 19 is an L-shaped bent flange portion, 20 is a hook, 21 is a latch locked by this hook, 22 is an auxiliary plate, and a latch housing portion 23 for housing and fixing the latch 21 in the center and mounting holes 12 at both ends. Is provided.

The fixing of the charging filter 9 to the air filter 6 is shown in FIGS. 3 and 4, and in FIG. 3, 12 is a charging filter fixing tool main body, which is formed by a connecting plate 26 connecting the fixing frame 25 in series at the center. ing. 11 is the air filter 6
A stepped hole provided above the thin portion 18 of the air filter 13 , 13 is formed in the charging filter fixing tool main body 24,
It is an engaging claw that engages with the stepped hole 11 of FIG.

Next, the operation will be described. First, the plurality of charging filters 9 are fixed by the charging filter fixture main body 12 above the thin portion 18 of the air filter 6 through the engaging claws 13 . The air filter 6 to which the charging filter 9 is attached is inserted along the rail 8 and is bent while being bent at the thin portion 18 by the guide rib 15 from the middle, and the hook 20 provided on the air filter 6 is latched by the latch 2.
1 and the air filter 6 is fixed to the front panel 4 by a fixture 1
Since only the second connecting plate 26 passes through, the depth dimension need not be changed. To remove the air filter 6, the flange portion 19 is pushed upward so that the hook 20 is disengaged from the latch 21 and can be taken out.

[0011]

As described above, according to the present invention, an air filter provided with a bendable thin portion on a frame and a fixing latch, and a plurality of air filters provided above the thin portion of the air filter are provided. Since the charging filter and the charging filter fixture made up of the frame body connected in series by the connecting plate are provided, it is not necessary to lift the air filter to release the latch when the air filter is inserted, and the depth dimension can be reduced.
Moreover, it can be attached and detached by bending toward the ceiling suction port.
