Use in the filter layered product at the humidification that humidification is formed with the filter lamination, when the humidification that adjacency is set in the mode that does not overlap each other is used the jut of filter, the protuberance of jut does not enter the depressed part of the humidification usefulness filter of adjacency, the humidification of adjacency does not overlap each other with filter, so the gap of can not inaccessible wind passing through and the humidification amount of stable output.For the humidification that the makes adjacency jut with filter does not overlap each other, for example the humidification of adjacency can be arranged at the position that differs from one another with the jut of filter.
As instantiation, be provided with the N kind of jut in the position that will depart from a circumferential direction (90/N) ° (wherein, N is the integer more than 2) humidification that forms with filter successively lamination of humidification is with in the filter layered product, the humidification of adjacency is not overlapping with the jut of filter, can be present in the position that differs from one another.
Fig. 1 ~ 4 are provided with the humidification involved in the present invention of wearing hole 2 that axle uses and a plurality of jut 3 with the schematic plan view of an example of filter for being illustrated on the filter ground 10.Fig. 1 is for to be illustrated in the situation of N=2 successively, depart from a circumferential direction (90/2) °=45 ° position is provided with 2 kinds of humidifications of jut 3 with the schematic plan view of filters.When 2 kinds of humidifications of lamination successively during with filter 1A and 1B, because humidification is not overlapping with filter 1A and 1B jut 3 separately, the gap of can not inaccessible wind passing through and the humidification amount of stable output.Fig. 2 is the humidification of situation that N=3 is shown the successively schematic plan view with filter, and Fig. 3 is the humidification of situation that N=6 is shown the successively schematic plan view with filter.
As other instantiation, as shown in Figure 4, humidification is arranged to respectively different circle-shaped of radius with the jut 3 of filter 1C and humidification with the jut 3 of filter 1D, in the situation that adjacency also can make jut 3 each other not overlapping.
Preferably wear hole or the location sign that axle is used at humidification with filter setting.Wear the hole that axle is used if arrange, then can not be offset ground lamination humidification filter.Fig. 5 and 6 is for illustrating successively N=2, depart from a circumferential direction (90/2) °=45 ° position is provided with 2 kinds of humidifications of jut 3 with the schematic plan view of filters.Wear the shape in the hole that axle uses without particular determination, but as Fig. 5 (I) in the situation of wearing the Kong Weizheng circle that axle uses, when humidification during with the rotation of filter layered product, humidification also rotates with filter, there is overlapping possibility in the humidification of adjacency with filter.Therefore, preferably wear the shape in the hole that axle uses not for just round.For example, as Fig. 5 (II) is in the situation of octagon wearing the hole that axle uses, and when humidification during with the rotation of filter layered product, humidification does not rotate with filter, so the humidification of adjacency is not overlapping in rotary course with filter, therefore preferred.But, octagon during such as N=2, wear in the situation of shape congruence in the hole that axle uses rotation (90/N) ° front and back in a circumferential direction, when when humidification passes axle and carries out lamination with filter, thus have humidification with the filter rotation or humidification that the anisotropy when passing causes adjacency with the jut of filter overlapping situation rarely.Therefore, such as the humidification filter of Fig. 6 (I), the location preferably is set with sign 11, or such as Fig. 6 (II) ~ (IV), preferably makes and rotate in a circumferential direction (90/N) ° front and back to wear the shape in the hole that axle uses not congruent.The location can arrange by printing with sign also can be by adding the indentation setting.In the situation that printing, the single face that can only be arranged at the filter ground also can be arranged at the two sides.
Humidification filter as shown in Figure 1 is for arranging the example of jut 3 by extruding, jut 3 only forms at the single face of filter ground 10.Fig. 7 is the schematic cross-section of the jut 3 under the dotted line XY of Fig. 1.Fig. 8 be the humidification on the jut two sides that is formed at filter ground 10 with filter 1E and 1F, depart from the jut circumferencial direction of humidification with filter 1E and 1F (90/2) °.Fig. 9 is the schematic cross-section under the dotted line ST of Fig. 8.(Fig. 8: opposing face solid line) is provided with jut 3B (Fig. 8: dotted line) by extruding at jut 3A.Like this, jut can form on the two sides of filter ground and also can only form at single face, but because humidification is not time-consuming with the preparation of filter, and the ground lamination of not makeing mistakes can be at lamination by making this jut towards same direction time the, so the more preferably side that only forms at single face of jut.
The shape of the jut that only forms by extruding not particular determination is the polygonal taper such as prism-shaped, circular cone, pyrometric cone such as cylindric, triangular prism shape, bowl-shape etc.But, the humidification of adjacency with the identical situation in the position of the jut of filter under, when the Breadth Maximum of jut is that the width of foot of jut is when following, in the situation that lamination humidification filter, jut enters the depressed part of the humidification usefulness filter of adjacency, humidification disappears with the gap between filter so that wind be difficult to by, the humidification amount reduces.Therefore, Breadth Maximum by making jut is greater than the width of the foot of jut, even the humidification of adjacency is identical with the position of the jut between filter, still so that jut do not overlap each other, the gap between humidification usefulness filter can be guaranteed, stable humidification amount can be guaranteed.
In a part of cutting the filter ground, in the method for vertical or incline direction bending, that the shape of jut is not limited to is circular-arc, horn shape etc. with respect to the filter ground.But, for example when the both sides of cutting equilateral triangle, when the base is bent into 90 ° with respect to the filter ground, if the humidification of adjacency is identical with the position of the jut of filter, then jut enters the notch portion of the filter ground of adjacency, gap between the filter ground disappears so that wind be difficult to by, the humidification amount reduces.Therefore, be present in jut by the zone with width longer than broken line width, even the humidification of adjacency is identical with the position of the jut between filter, the humidification of adjacency can not enter the notch portion of the jut that is present in humidification usefulness filter yet with the jut of filter, can guarantee the gap between ground, stable humidification amount can be provided.
The shape of jut is as mentioned above without particular determination, but can be the shape of " length of the circumferencial direction of the length＞jut of the radial direction of the humidification usefulness filter of jut, and the length of the radial direction of the humidification of jut usefulness filter＜humidification radius of filter ".Figure 10 is for being provided with the humidification involved in the present invention of wearing hole 2 that axle uses and a plurality of jut 3 with the schematic plan view of an example of filter on the expression filter ground 10.Figure 11 is the enlarged drawing of the jut 3 of Figure 10, and symbol A is " length that the humidification of jut is used the radial direction of filter ", and symbol B is " length of the circumferencial direction of jut ".As " humidification of jut is with the length of the circumferencial direction of the length＞jut of the radial direction of filter; and the humidification of jut is with the jut of the length of the radial direction of filter＜humidification with the radius of filter " and concrete shape, can list the elongated shapes such as shown in figure 11 fillet rectangle, rectangle as shown in figure 12, ellipse.
