2. Description of the Related Art Generally, an air filter for an air conditioner is provided near a suction port of the air conditioner and is detachably attached along a guide rail portion for mounting provided on a front grill of the air conditioner. It is supposed to be done.
Then, in the air filter 110 of the conventional air conditioner, for example, as shown in FIGS. 5A and 5B, the mesh portion 102 is fixed to the wide lattice-shaped frame portion 101. The frame portion 101 is configured to be detachably mounted along the mounting guide rail portions 103, 103 provided in the air conditioner. However, when the net portion 102 is fixed to the frame portion 101 in this way, when the air filter 110 is removed from the air conditioner and cleaned, the lattice-shaped frames 101a of the frame portion 101 interfere with each other. There was a problem that it was difficult to clean.

A filter is described in Japanese Patent Laid-Open No. 11-47527. This is shown in FIG.
As shown in (b), in a filter composed of a filter body 201 made of a predetermined filter material and a filter frame 202 supporting the filter body 201, the filter body 201 is formed of a flexible member, The filter body 202 is detachably attached to the filter frame 202, and the filter body 201 is formed by a bag-shaped member into which the filter frame 202 can be inserted. Further, as shown in FIGS. 7A and 7B, a filter body 203 made of a predetermined filter material and a filter body 2
In the filter configured with the filter frame 204 supporting 03, the filter body 203 is formed of a flexible member, is detachably attached to the filter frame 204, and the filter body 203 can be detachably coupled at both ends. It is formed by a sheet-shaped member.

As shown in FIGS. 8 (a) and 8 (b), the filter body 20 comprises a filter body 205 made of a predetermined filter material and a filter frame 206 supporting the filter body 205.
5 is formed of a flexible member, is detachably attached to the filter frame 206, and the filter body 205 is formed of a plate-like member, and the end of the filter body 205 is inserted into the filter frame 206 from a predetermined direction. A possible support portion 206a is provided.

However, FIGS. 6 (a) and 6 (b) and FIG. 7 (a)
In the case shown in (b), since the filter bodies 201 and 203 are in the shape of a bag, there is a problem that it becomes a double structure and it becomes difficult for air to pass through. Furthermore, the material of the filter bodies 201 and 203 is more than double. There was a problem that it was uneconomical because it was necessary. In addition, FIG.
In the case shown in (b), the filter body 205 was formed of a thick material, and was a plate-like one instead of using a mesh.

Further, Japanese Patent Laid-Open No. 64-31942 discloses a kitchen ventilation fan. This is shown in FIG. 9, FIG.
As shown in FIG. 11, a ventilation fan main body 308 including a blower 304, a filter holding frame 309 provided on the front surface of the ventilation fan main body 308, and the filter holding frame 3
So as to cover the front surface of the filter frame 310, the tape-shaped holder 312 that is attached to the inner surfaces of both sides of the filter frame 310 and forms one side of the surface fastener, and the front surface of the filter frame 310. The tape-shaped holders 312 arranged on both sides of the filter frame 310 are arranged on both sides.
And a filter 311 made of a non-woven fabric that is engaged with and held by the. However, this uses a filter 311 for a ventilation fan using a blower, has a different application from the present invention, and was not applicable to the present invention.
