2. How to Use the Filter Unit 1 How to use the filter unit 1 will be described with reference to FIG. The filter unit 1 can be attached to the air conditioner unit 49 . The air conditioner unit 49 has a case 51 and a blower 53 .

The case 51 is a rectangular tubular member having an inlet 55 and an outlet 57 . The blower 53 is installed inside the case 51 . Air generated by blower 53 enters case 51 through inlet 55 , flows along direction F, and exits through outlet 57 .

The case 51 has filter holding guides 59 . The filter holding guide 59 is provided on the inner surface of the ceiling portion 51A of the case 51 . The filter holding guide 59 has a groove 61 opening downward.

A filter mounting hole 63 is formed in the bottom portion 51B of the case 51 . The position of the filter mounting hole 63 is below the filter holding guide 59 . The filter mounting hole 63 is normally covered with a cover 65 . The cover 65 includes a cover body 67 and packing 69 . When the filter mounting hole 63 is covered with the cover 65, the packing 69 enters the inside of the case 51 rather than the bottom portion 51B.

The air conditioner unit 49 is attached to a vehicle, for example. The air conditioner unit 49 is installed, for example, in a place where the space below the bottom portion 51B is narrow.
When attaching the filter unit 1 to the air conditioner unit 49 , first, the cover 65 is removed from the case 51 . Next, the filter unit 1 is pushed into the case 51 from below the case 51 through the filter mounting hole 63 .

At this time, the filter unit 1 is pushed in with the projecting portion 27 facing forward. Further, when the filter unit 1 is located below the case 51, the connection member 11 is bent so that the filter unit 1 is changed to a form in which the sides 39 and 43 are bent with respect to the sides 15 and 19 (hereinafter referred to as a bent form). ). The bent form is a form in which the end portion 23 is bent inside.

When the entire first resin frame 3 is pushed into the case 51, the connection member 11 is extended, so that the filter unit 1 is changed to a configuration in which the sides 15 and 19 and the sides 39 and 43 are aligned ( hereinafter referred to as a linear form). Further, the filter unit 1 is pushed into the case 51 and the projecting portion 27 is inserted into the groove 61 .

Finally, the cover 65 closes the filter mounting hole 63 . The packing 69 contacts the side 41 . The filter unit 1 is fixed to the case 51 by inserting the protruding portion 27 into the groove 61 and by supporting the side 41 with the packing 69 from below.

3. Effects of the Filter Unit 1 (1A) The filter unit 1 is provided with the bendable connecting member 11 so that it can be folded. Therefore, even if the space below the bottom portion 51B is narrow, the filter unit 1 can be easily pushed into the filter mounting hole 63 as shown in FIG.

(1B) When removing the filter unit 1 from the air conditioner unit 49 , for example, the second resin frame 7 is pulled in the direction of the filter mounting hole 63 . At this time, force is applied to the interface between the end portion 11A and the first adhesive surface 25 . Further, force is applied to the interface between the end portion 11B and the second adhesive surface 47 as well.

The direction of the applied force is a direction perpendicular to the outer peripheral surface 13A and the outer peripheral surface 37A. The first adhesive surface 25 is a surface that intersects with the outer peripheral surface 13A. Therefore, the angle formed by the direction of the applied force and the first adhesive surface 25 is small. Also, the angle formed by the direction of the applied force and the second adhesive surface 47 is small.

As a result, even when the second resin frame 7 is pulled in the direction of the filter mounting hole 63 , the end portion 11A is difficult to separate from the first adhesive surface 25 and the end portion 11B is difficult to separate from the second adhesive surface 47 .
(1C) The connecting member 11 is made of nonwoven fabric. Therefore, even if the connecting member 11 is repeatedly bent, the connecting member 11 is less likely to deteriorate.
