2. Details of Embodiment <First Embodiment Specialized for Corresponding to Wall Ventilation Fan>
FIG. 1 illustrates a ventilation passage assembly 190, which is completed by assembling a ventilation passage assembly kit according to a first embodiment specializing in adapting to a wall ventilation fan, by a longitudinal section. 2 to 8 illustrate various parts constituting the ventilation passage assembly kit.

  As illustrated in FIG. 1, the ventilation passage assembly kit is a kit for forming a ventilation passage 180 from an indoor floor 171 to a ventilation fan 170 on a wall surface 173, and a main body part in which the passage is assembled by bending and joining. 100, attachment parts 107, 110, 140, and 150 attached to the main body part 100, and a fixing part 160 for fixing the assembled main body part to the wall surface.

  As illustrated in FIG. 2, the main body component 100 has a long rectangular back plate portion 102 having an insertion hole 106 into which the frame of the ventilation fan is inserted, and a size substantially equal to the back plate portion 102. A pair of long side plates for connecting the long side edge of the back plate 102 and the long side edge of the front plate 101 to each other. 103 and 104 and the joining margin 105 are integrally formed by punching or cutting. In particular, a press groove or the like is formed at a boundary portion (shown by a solid line) where each of the portions 101, 102, 103, 104, and 105 is in contact with each other so that it can be easily bent in the same process or a separate process. By bending the main body part 100 along the press groove or the like and fixing the joining margin 105 to the edge part of the side plate part 103 by adhesion or double-sided tape or the like, a passage having a square cross section can be formed. The press groove may be a shallow kerf.

  The material of the main body part 100 is not particularly limited. As illustrated in FIG. 3, a decorative paper or a decorative cloth is pasted on the surface of the corrugated cardboard 100B having a thickness of several millimeters, and the back surface (the ventilation passage 180). Side) and a composite material having an aluminum foil 100C for preventing condensation. Although not particularly limited, a material whose outer surface is laminated with vinyl or the like may be used. Although not shown, it may be constituted by a thin plastic plate, or may be strengthened by adopting a honeycomb structure as a core material. When using a thin plastic plate, it is not necessary to attach an aluminum foil.

  As the attachment part, a packing 107 made of, for example, a sponge having flexibility, which is fixed to a peripheral portion of the insertion hole 106 formed in the back plate 102 is provided. The packing 107 may be fixed to the main body part 100 first, or may be fixed later by bonding or the like during assembly. As is clear from FIG. 1, even if a gap is formed between the insertion hole 106 and the frame of the ventilation fan 170, the packing 107 provided at the peripheral edge of the insertion hole 106 of the main body part 100 passes air to the passage 180 through the gap. Suppresses inflow.

  The insertion hole is formed larger than the size of the frame of the ventilation fan, and the length of the main body part 100 and the size of the insertion hole 106 are actually processed even if the height of the ventilation fan provided on the wall surface is different. It can be easily handled without any problems. Since the packing 107 is also sized to be disposed at the periphery of the insertion hole 106, the ventilation path is opened to the outside even if there is a relatively large gap between the ventilation fan and the insertion hole 106.

  The opening restricting part is provided with a top plate part and a bottom plate part each having an opening formed in the main body part, and by adjusting the overlapping amount of the mask plate with respect to the opening of the top plate part, It is also possible to configure so as to selectively determine the degree of opening.

  As another mounting part, as illustrated in FIG. 7, it has a reinforcing part 150 that is assembled to form a cylindrical body and that is inserted into the passage by the main body part to form a rib that reinforces the passage. . For example, the reinforcing component 150 has a planar shape substantially equal to the cross-sectional shape of the ventilation passage 180, and is configured by laminating and fixing three plates having openings 150A. The reinforcing component 150 is inserted and arranged at several places in the ventilation passage 180 and fixed. The reinforcing component 150 facilitates improving the strength of the ventilation passage 180. The reinforcing component is not limited to a configuration in which plates are laminated, and may have a structure in which a plate is bent to form a cylinder.

  The fixing component 160 is a magic tape (registered trademark, hereinafter omitted) illustrated in FIG. 8, a double-sided tape not shown, or the like. The loop 161 of the magic tape 160 is bonded to the wall surface 173, and the hook 162 is bonded and fixed to the surface of the back surface portion 102 of the main body component 100.

  By using the assembly kit, air can be prevented from flowing into the passage from the gap between the insertion hole 106 and the ventilation fan 170, and the ventilation passage can be assembled by setting the ventilation flow rate from the floor as desired. Anyone can easily assemble a ventilation passage with functions. Since it is provided as an assembly kit, construction costs are reduced, and the ventilation passage from the floor can be configured at low cost.
