Also in the above honeycomb-shaped air filter 95, the first sheet 91 having pleats formed on the entire surface is replaced by the flat second sheet 9
It is composed by stacking two. However, Figure 1
As shown in FIG. 3 (B), the first sheet 93 installed directly above or below the certain first sheet 91 and one second sheet 92 has the ridge line 9 of the mountain portion in the first sheet 93.
30 and the bottom line 919 of the valley portion of the first sheet 91 are overlapped so as to intersect each other.

製造コストが高くなる。However, the air filters 9 and 95 have some problems. That is, in manufacturing the air filters 9 and 95, it is necessary to cut the first sheet 91 and the second sheet 92 according to the size of the frame body 99. Since the size of the frame body 99 depends on the air conditioner or the like to which it is assembled, it is necessary to manufacture the air filters 9 and 95 separately for each device. Therefore, the manufacturing cost becomes high.

フィルタの製造方法にある。According to the present invention, a band-shaped filter medium is folded in a direction oblique to the longitudinal direction to alternately form peaks and valleys, and the band-shaped filter medium is folded back at a predetermined length. The method for manufacturing an air filter is characterized in that the flow paths of the layers are sequentially laminated, and the flow paths of the stacked layers intersect with the flow paths of the adjacent layers adjacent to each other.
【0013】本発明において最も注目すべき点は,積層
された各層の流路は隣接する隣接層の流路と互いに交錯

定の角度,即ち長手方向に斜め状となるように折る。The band-shaped filter medium is a sheet whose one side is significantly longer than the other side. Then, the band-shaped filter medium is fold-folded obliquely with respect to its longitudinal direction to form a corrugated body having alternating peaks and valleys (FIG. 1). The peaks and valleys of the corrugated body may have sharp tips or may be rounded. When the band-shaped filter medium is folded, the folding line is folded such that the folding line is inclined at a constant angle other than 0 degree with respect to each side of the filter medium, that is, in the longitudinal direction.

他に,脱臭機能を与えることができる。As the band-shaped filter medium, in addition to a general filter medium, for example, a non-woven fabric made of electret fibers can be used. The material is, for example, polypropylene or polyester. In addition, it is also preferable to use activated carbon fiber paper or the like for the band-shaped filter medium. In this case, the air filter can be provided with a deodorizing function in addition to the normal air filtering function.

あれば折り返し長さは変化する。It is preferable that the air filter is mounted on a frame made of resin or the like and used as a filter device. In this case, the strength is greatly improved compared to the case where the air filter is used alone. Further, when the air filter is assembled to the frame body and used, the predetermined length of the folding back at the time of stacking is almost equal to the inner diameter of the frame body. The predetermined length of the folding back is constant if the shape of the frame body is, for example, a rectangle, but the folding length changes if the shape of the frame body is, for example, a trapezoid.

That is, it is preferable to stack so that the lower end of the valley portion partially abuts. Further, it is preferable that both of them are adhered and fixed at the time of contact. As a result, the air filter does not have to lose its shape due to the pressure of air or the like, and is excellent in strength. In the adhesive fixing, for example, an adhesive, hot melt or the like is used to join the contact points of the peaks and valleys.

る。Next, it is preferable that a plurality of the fold-folded band-shaped filter media are laminated in advance to form channels intersecting with each other. That is, for example, two fold-folded band-shaped filter media are previously laminated and abutted as described above to form a laminate in which mutually intersecting flow paths are formed. After that, the above-mentioned laminated body can be folded back and laminated in sequence for each predetermined length (Example 2). According to this method,
The number of times the band-shaped filter medium is folded back is reduced. Therefore, the number of processing steps can be reduced and the manufacturing cost can be reduced.
