フイルターが使用されている。
Filters used in small air purifiers with an overcapacity of 5 m 3 /min or less, such as those used indoors in homes and cars, require periodic replacement.
Since anyone can replace the filter, not an air conditioning specialist, a simple cassette-shaped filter is usually used.

ルターにとつては重大な欠点であつた。 However, in order to obtain easy replacement, all of these use an outer frame formed by molding or assembling rigid plastic or metal. This increases the cost of the mold required for molding and the processing cost required for assembly, making the cassette filter expensive. This was a serious drawback for cassette filters that required periodic replacement.

It lacked sex.

The cassette filter according to the present invention will be explained according to the drawings. FIG. 1 shows an embodiment of a cassette filter according to the present invention, and FIG. 2 is a partial sectional view thereof, showing a pleated nonwoven material 1 and a nonwoven fabric outer frame coated with an adhesive layer 3 on the surface. 2 are combined. The nonwoven material 1 is appropriately selected depending on the type of dust to be collected, but in particular, in order to collect fine dust such as indoor cigarette smoke, a laminated filter of microfine fiber made by the melt blow method is used. Good air cleanliness can be obtained by using an electric filter or an electret filter.
又、材は、薄手の不織布をひだの高さ10mm以
上にひだ折りしたものを使用することが好適であ

として使用出来る。 In addition, it is preferable to use thin non-woven fabric folded to a pleat height of 10 mm or more, but it is also preferable to use thick non-woven fabric, etc., with a thickness of 10 mm or more by veneering or laminating. If so, it can be used as a material for the present invention.
外枠２は、粗密２層構造の厚み方向に弾性を有

能となる。 The outer frame 2 is formed of a nonwoven fabric having a coarse and dense two-layer structure and has elasticity in the thickness direction.
It is advantageous to use non-woven fabrics with an average density of at least 0.3 mm and an average density of at most 0.3. This is because if the thickness is less than 2 mm, it will not be compatible with the filter installation part of the air purifier, and if a nonwoven fabric with a density of more than 0.3 is used, the elasticity in the thickness direction will be low. This is because the filter does not function as a cassette filter that can be easily replaced because it lacks compatibility with the installation location. By using a low-density nonwoven fabric with a thickness of 2 mm or more, the filter installation part, which is designed to be slightly smaller than the size of the cassette filter of the present invention, has a pressing force due to elasticity in the thickness direction and surface friction resistance. The filter can be fixed without requiring any fixing means.
特に厚みが2.5〜4.6mmで、平均密度が0.07〜
0.15の粗密２層構造の不織布の使用は更に有利な

には、高密度不織布の有する剛性が、後に述べる
接着剤の剛性を補助するという作用を示すことで
ある。 Especially when the thickness is 2.5~4.6mm and the average density is 0.07~
The use of a nonwoven fabric with a two-layer structure of 0.15 density shows further advantageous characteristics. First, to explain the effect of the dense surface in a two-layer structure, firstly, when applying an adhesive with low solution viscosity or melt viscosity, applying it to the dense surface side prevents the adhesive from sinking into the nonwoven fabric. It is possible to form a suitable adhesive layer on the nonwoven fabric, and the second
The reason is that the rigidity of the high-density nonwoven fabric assists the rigidity of the adhesive described later.
又、粗面の不織布は、柔軟であるために、空気

ーの挿着をより容易にするとともに、適度に圧縮
されシール材としての機能をも示す。 Moreover, since the nonwoven fabric with a rough surface is flexible, it facilitates the insertion of the cassette filter into the filter installation part of the air cleaner, and also functions as a sealing material when compressed appropriately.
次に、不織材と外枠を結合する接着剤である

ル系、硬質ウレタン系等が適宜選択され得る。 Next, the adhesive that connects the nonwoven material to the outer frame is selected from materials that have the necessary rigidity for inserting the cassette. Rigidity here does not necessarily mean that it is as rigid as conventional plastic or metal outer frames, but rather that it is not as flexible as soft rubber or film, and that it does not require the slight pressure applied when inserting the cassette. Hardness that can withstand Therefore, depending on the adhesive method, for example, in the case of hot melt adhesive, polyolefin type, ethylene-vinyl acetate copolymer type, polyamide type, polyester type, etc.
For solution or emulsion adhesives, acrylic adhesives, ethylene vinyl acetate adhesives, vinyl chloride ethylene adhesives, etc. may be selected as appropriate; and for reactive adhesives, epoxy adhesives, phenol adhesives, hard urethane adhesives, etc. may be selected as appropriate.

全て本考案でも採用出来る。例えば、材のひだ

る。 Next, the method for making the cassette filter will be explained. All of the commonly used methods of gluing the material and the outer frame can be used in the present invention. For example, there is a method in which hot melt resin is applied to the pleated side surface of the material and the material is bonded to the outer frame, or a method in which adhesive is applied to the outer frame and then the material is inserted and bonded.
In addition, a method of sandwiching a hot melt film between the material and the outer frame and heat-sealing the material can also be adopted.
次に本考案のカセツトフイルターを実施例に基
