Therefore, the ridge portion 3 is projected on one surface 2 and the ridge portion 5 is a concave ridge, and the ridge portion 5 is projected on the other surface 4 and the ridge portion 3 is a concave ridge. Has become. It should be noted that the intersection of the ridge portion 3 and the ridge portion 5 does not protrude from any surface of the substrate 1. When a large number of such substrates 1 are stacked to form a ventilation device, the protrusions 3 on one (upper) surface 2 of the lower substrate 1 and the other (lower) of the upper substrate 1 that overlap each other. The ridges 5 of the surface 4 are arranged so as to face in the same direction, and the ridges 5 and 3 which are vertically stacked are bonded and fixed to each other to form a wall, and a large number of wide air passages 6 are formed. . In order to prevent air from leaking from the direction orthogonal to the passage 6, a spacer 7 having a thickness substantially the same as the thickness of the passage 6 is interposed and fixed at the end portion between the substrates 1 and 1 so as not to leak. ing.

In this way, the substrate 1 is laminated in such a manner that a plurality of passages 6 oriented in the direction of arrow X and a plurality of passages 6 oriented in the direction of arrow Y are alternately formed vertically to form a block-type ventilation device. Of.

[0006]

However, in the above-mentioned conventional ventilation device, when a plurality of sheet-like substrates 1 each having a substantially square plan shape are stacked and configured, the lower substrate 1 is formed.
The ridges 3 on one (upper) surface 2 and the ridges 5 on the other (lower) surface 4 of the upper substrate 1 are arranged so as to face in the same direction, and the ridges 5 are vertically overlapped. , 3 must be adhered and fixed together to form a wall, and care must be taken not to cause a positional deviation between the upper and lower ridges 5, 3, which is a problem. Further, as described above, the spacer 7 having substantially the same thickness as the thickness of the passage 6 must be interposed at the end portion between the substrates 1 and 1, and the spacer 7 needs to be aligned with the substrate 1. Also in this respect, there is a problem that it takes time.

The present invention solves such a problem, and an object of the present invention is to make the manufacturing easier than the conventional ventilation device.

[0008]

In order to solve this problem, the present invention has a large number of parallel projecting ridges projecting from one surface and located at equal intervals and projecting from the other surface. A large number of sheet portions having parallel ridges which are parallel to each other and are arranged at equal intervals and which are orthogonal to the ridge, and a large number of parallel ridges which are projected from one surface and are arranged at equal intervals. A plurality of sheet portions each having a ridge portion and protruding from the other surface and having ridge portions that are parallel to each other and are arranged at equal intervals and are orthogonal to the ridge portion. In the state in which the sheet portions of are overlapped with each other, the ridge portions of one sheet portion and the ridge portions of the other sheet portion face in the same direction and are vertically overlapped, and the overlapped ridge portions are bonded and fixed. The walls of the passage are formed, and Wherein the two sheets portion is made provided with a convex portion for the spacer along the side portions.

[0009]

With this configuration, by folding the substrates having the two sheet portions on each other, the ridge portions of one sheet portion and the ridge portions of the other sheet portion face each other in the same direction, and vertically overlap each other. Since the wall of the passage can be formed by adhering and fixing the overlapping ridges to each other, there is no problem of positional deviation between the ridges as in the conventional example, and the spacer as in the conventional example is also unnecessary. Therefore, the work efficiency at the time of manufacturing is significantly improved, and the cost can be reduced.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. First, the first embodiment shown in FIGS. 1 to 5 will be described. Reference numeral 11 is a substrate integrally forming two sheet portions 12a and 12b having a substantially square planar shape, which constitutes a ventilation device, and one sheet portion 12a. A large number of parallel projecting ridges 14a protruding from one surface (upper surface) 13a and located at equal intervals are formed on the other side, while the other surface (lower surface) 15a is formed.
A large number of more protruding ridges 16a which are parallel to each other and are arranged at equal intervals and are orthogonal to the ridges 14a are formed by press molding. Further, the other sheet portion 12b is formed with a large number of parallel projecting ridge portions 16b protruding from one surface (upper surface) 13b and located at equal intervals, and protruding from the other surface (lower surface) 15b. A plurality of ridges 14b which are parallel to each other and are arranged at equal intervals and are orthogonal to the ridges 16b are formed by press molding.
Therefore, the ridge portion 14a is projected on one surface 13a of the one sheet portion 12a, the ridge portion 16a is a concave portion, and the ridge portion 16a is projected on the other surface 15a.
The portion 14a is a concave line. The intersection of the ridge 14a and the ridge 16a does not protrude from any surface of the seat 12a. The same applies to the other sheet portion 12b. The ridge portion 16b projects on one surface 13b, the ridge portion 14b is a concave portion, and the ridge portion 14b projects on the other surface 15b. The ridge 16b is a concave ridge. The intersection between the ridge 16b and the ridge 14b does not project from any surface of the seat 12b.

When the two sheet portions 12a and 12b are folded over each other, the ridge portion 14 of one sheet portion 12a is folded.
a and the ridge portion 16b of the other sheet portion 12b face in the same direction and are vertically overlapped with each other, and the overlapped ridge portions 14a and 16b.
The walls of the passage 17 are made by adhering and fixing the comrades.

By the way, the ridge portion of the seat portion 12a
On the upper surface in the vicinity of a pair of opposite sides parallel to 14a, the protrusions 1 for spacers having a height substantially the same as the height of the passage 17 are provided.
The seat portion 12 is formed with parallel lines 8 and 18 and the upper ends of the protruding portions 18 and 18 overlap the seat portion 12a.
It is adhered and fixed to the back surface of b so that air does not leak from a direction orthogonal to the passage 17.

Further, the ridge portion 15 of the other sheet portion 12b
On the back surface in the vicinity of a pair of opposite sides parallel to the above, ridges 19 and 19 for spacers having the same height as the ridges 18 are formed parallel to the ridges 15a.

As described above, a large number of substrates 11 are formed by laminating the two sheet portions 12a and 12b and adhering and fixing them. For example, the ridge 16a on the lower surface of the upper substrate 11 is laminated.
The ridges 14b on the upper surface of the lower substrate 11 and the ridges 14b on the upper surface of the lower substrate 11 are vertically overlapped in the same direction, and the overlapped ridges 16a and 14b are bonded and fixed to each other to form a wall of the passage 17. As a result, a large number of passages 17 oriented in the arrow X direction and passages 17 oriented in the arrow Y direction are alternately formed in the upper and lower directions to form a block-shaped ventilation device.

Therefore, the block-shaped ventilation device is attached to the wall that divides the interior and the exterior of the building. At that time, the ventilation device is divided into two equal parts with one diagonal line as a boundary when viewed from a plane. Install so that one half projects outside and the other half projects indoors.

When using the above ventilation device to ventilate the room, the passage 17 directed in the direction of the arrow X serves as a discharge passage for the air in the room, and the passage 17 directed in the direction of the arrow Y serves as an inflow passage for the air outside the room. Becomes

By the way, synthetic resin or paper is used as the material of the substrate 11 which constitutes the ventilation device, and the material is selected according to the application. That is, when heat exchange is required between the outflowing indoor air and the inflowing outdoor air, the substrate 11
May be made of synthetic resin such as vinyl chloride, and when both heat exchange and humidity exchange are required, the substrate 11 may be made of hygroscopic paper. Further, even if a hygroscopic material is mixed with the resin, the hygroscopic property can be provided.

As described above, when paper is used as the material of the substrate 11, the strength is weaker than that of the synthetic resin substrate, and in order to increase the strength especially in the peripheral portion, the second shown in FIG. 6 and FIG. As in the embodiment, the folding piece 20 is integrally provided on the peripheral portion of the substrate 11 in which the two sheet portions 12a and 12b are developed to form the substrate 11
It is also possible to fix it to the peripheral part with an adhesive. In the second embodiment, the folding piece 20 is 1 in the peripheral portion of the substrate 11.
The sheets are stacked to form a double structure, but a triple structure or a quadruple structure can be used.

[0019]

As described above, according to the present invention, the ridges of one sheet portion and the ridge portions of the other sheet portion are the same by folding the substrates having the two sheet portions on each other. Since the overlapped ridges face each other in the vertical direction, and the overlapped ridges can be bonded and fixed to form a wall of the passage, there is no problem of positional displacement between the ridges as in the conventional example, and The spacer as in the conventional example is not necessary, and the work efficiency at the time of manufacturing is significantly improved, and the cost can be reduced.
