Since it is fastened and fixed to the plate surface of the top plate portion 10 at 22, it is placed on the plate surface of one slope outside the top plate portion 10.

  As the ventilation fan 3, a sirocco fan that generates an air flow from below to above is provided so as to be rotated by a drive motor. As shown in FIG. 3, the ventilation fan 3 includes a base 30 and a housing 31, and covers the housing 31 from the upper side and is relatively fixed by the base 30 and four planting bolts 32. It is held by the housing 31.

  The base 30 of the ventilation fan 3 includes a central receiving plate portion 30b provided with a circular hole 30a (see FIG. 2) on the plate surface, and standing plate portions 30c and 30d provided at both ends of the receiving plate portion 30b. Is formed. The housing 31 is formed of a cylindrical surrounding frame portion 31a that houses the ventilation fan 3 therein, and a support plate portion 31c that covers the upper side of the surrounding frame portion 31a and has three holes 31b provided on the plate surface. ing.

  The ventilation fan 3 (see FIG. 2) is assembled inside the building 1 because the drive motor is electrically connected to the solar cell 2 through the power line 20 drawn from the plate surface of the top plate 10. Further, the plates of the standing wall portions 11 and 12 are maintained so as to maintain the horizontal direction by fixing the standing plate portions 30c and 30d to the inside of the standing wall portions 11 and 12 extending in the longitudinal direction of the top plate portion 10 with the fastening bolts 33. It is installed between the faces.

The ventilation fan 3 (see FIG. 1) is assembled and installed at a substantially central position of the building enclosure 1. In the building 1, vents 15 a, 15 b, 16 (see FIG. 2, only one side is shown) have standing wall portions 11 on both sides extending in the longitudinal direction of the top plate portion 10 on both sides adjacent to the installation position of the ventilation fan 3. 12 is provided. The vents 15a, 15b, and 16 are formed as vent holes that are formed by projecting a plurality of blades obliquely upward inward of the standing walls 11 and 12 while maintaining a ventilation gap.

A heat insulating foam 17 is laid and stuck on the inner surface of the top plate 10 (see FIG. 2). Inside the building enclosure 1, partition frames 18 , 19 surrounding the vent holes 15 a , 15 b , 16 on both sides are assembled over the plate surfaces of the standing wall portions 11, 12 (see FIG. 1).

  The partition plates 18 and 19 are directed downward from the side plate portions 18a and 19a (only one side is shown) on both sides facing the longitudinal direction of the building 1 and the top plate portions 18b and 19b extending between the side plate portions 18a and 19a. It is bent so as to exhibit a U-shape. Further, the lower side portions of the side plate portions 18a and 19a are notched according to the roof slope, and a plurality of vent holes 18c and 19c are provided on the plate surfaces of the top plate portions 18b and 19b.

  The ridge wrap 4 is formed in an umbrella shape corresponding to the gradient of the roof by bending the center of the plate surface in the longitudinal direction (see FIG. 1). In the center of the plate surface, three elongated holes 40a, 40b, 40c facing in the longitudinal direction are provided corresponding to the mounting position of the ventilation fan 3 and the opening positions of the vent holes 15a, 15b, 16. Both end surfaces in the longitudinal direction are bent as L-shaped step portions 41a and 41b corresponding to the height of the rafter described later.

On the plate surface of the ridge wrap 4, substantially quadrilateral draining frames 42 a, 42 b, 42 c having a rising width lower than the installation height of the ridge enclosure 1 surround the opening positions of the long holes 40 a, 40 b, 40 c. It is attached. Further, the support plates 43a and 43b of the ward 1 are placed and fixed to the draining frames 42b and 42c near both ends.

  In order to install and install the house building ventilation device, first, as shown in FIG. 4, a base plate that forms both slopes of the roof so that the building wrap 4 covers the ridge line of the building so as to cover the ventilation gap G of the building. Apply to B and fix. The ridge wrap 4 may be formed by covering the side surfaces of the step portions 41a and 41b with the plate surfaces closer to both ends on the upper side of the rafter W, and attaching the lower surface portions of the step portions 41a and 41b to the field plate B and fixing them with screws.

  Next, the building enclosure 1 is covered with the building enclosure 4 and the screws 5 are screwed onto the plate surfaces of the support plates 43a and 43b from the plate surfaces of the standing wall portions 11 and 12 (see FIG. 1). Install and fix to the ridge wrap 4. In the mounted state of the ward 1, the partition frames 18 and 19 are fitted to the outside of the draining frames 42b and 42c, and the ventilation fan 3 is relatively positioned to the inside of the draining frame 42a. In addition, the lower surface part of step part 41a, 41b is taken in below the roof flat plate R laid and installed on the board surface of the field board B. As shown in FIG.

In the house building ventilator with a solar cell driven ventilation fan installed and installed in this manner, the solar cell 2 is placed on the plate surface outside the top plate 10 and the power line 20 of the solar cell 2 is connected to the solar cell 2. for connecting in a mounting surface the ventilating fan 3 draws the interior of the building enclosure 1 from the plate surface of the top plate portion, rainwater prevented from infiltrating into the interior of To囲1 from the installation surface of the solar cell 2, for ventilating fan 3 Prevents the effects of rainwater.

In addition, the vent holes 15a, 15b, 16 are provided on both sides of the standing wall portions 11, 12 extending in the longitudinal direction of the top plate portion 10 on both sides adjacent to the installation position of the ventilation fan 3, and are surrounded by the partition frames 18, 19. For this reason, the use durability of the ventilation fan 3 can be enhanced by preventing direct influence of rainwater entering the inside of the building enclosure 1 from the vents 15a, 15b, and 16.

In the installation and installation, apart from the building enclosure 1 in which the solar cell 2 and the ventilation fan 3 are assembled and mounted, long holes 40a, 40b and 40c corresponding to the ventilation gap G of the building portion are defined along the longitudinal direction of the center of the plate surface. Since a plurality of building wraps 4 are provided at intervals, and the building enclosure 1 is assembled using the building wraps 4 as substrates, the installation work on the roof can be reduced and the entire apparatus can be easily installed and installed.

Further, the Totsutsumi 4 elongated holes 40a, 40b, provided three 40c into constant intervals along the longitudinal direction of the plate surface a center, thus does not commensurate with the intermediate of the elongated hole 40a installing a ventilation fan 3, on both sides of the long Since the building enclosure 1 provided with the vent holes 15a, 15b, 16 corresponding to the holes 40b, 40c is provided, the influence of rain water on the ventilation fan 3 can be prevented reliably, and the entire apparatus can be easily installed and installed.

In the house building ventilation device, the ventilation fan 3 rotates using the solar cell 2 as power. As the ventilation fan 3 rotates, indoor air is sucked into the building enclosure 1 from the long holes 40a, 40b, and 40c of the building wrap 4 and forced to the outside from the vents 15a, 15b, and 16 of the building enclosure 1. Discharged. The indoor air sucked from the long hole 40a of the wing 4 flows into the inside of the vent holes 18c, 19c of the partition frames 18, 19, and is discharged to the outside from the vent holes 15a, 15b, 16 of the wing enclosure 1.

  Since rainwater is blocked by the garage vents 15 a, 15 b, 16 of the building 1, it can be prevented from entering the inside of the building 1. Should rainwater enter the interior of the building 1 through the vents 15a, 15b and 16, the rainwater can be prevented from moving indoors by the drainage frames 42a, 42b and 42c.
