  The present invention relates to a building ventilation device provided with a solar cell module, and more particularly, to a building ventilation device excellent in workability capable of arranging the solar cell module at an optimum angle regardless of the gradient of the roof.

Conventionally, as a ventilation device that naturally ventilates hot air and moisture trapped in the attic, as shown in FIG. There is a ridge ventilation device 100 with supporting legs 300 supported on top. In this ridge ventilation device 100, the support leg 300 is formed integrally with the canopy part 200, and the support leg 300 is installed on the ridge part of the roof a by fixing the support leg 300 to the through plate i of the roof a with a bolt 110. . The support leg 300 is provided with a ventilation slit 400 communicating with the outdoors from the ventilation opening c, and hot air and moisture in the attic d are discharged to the outdoors from the ventilation opening c through the ventilation slit 400. It has a structure.
However, natural ventilation by the ventilation slit 400 alone does not provide sufficient exhaust capability. Therefore, it may be possible to forcibly ventilate by installing a ventilation fan. However, if the ventilation fan is operated using an indoor power supply, electricity costs will be charged, and facilities and wiring for connecting the indoor power supply and the ventilation fan will be charged. The work is complicated and construction becomes difficult.

On the other hand, as a building structure equipped with a solar cell module, the upper side of the ventilation opening of the building is covered with left and right inclined side surfaces formed in a substantially mountain shape, the solar cell module is installed on one inclined surface, and the other inclined surface Some have been provided with ventilation louvers on the surface. And it has also been proposed to forcibly ventilate by providing a ventilation fan in the internal space of the ridge and supplying and operating electricity from the solar cell module (see, for example, Patent Document 1).
However, since this ridge structure is a structure in which the angle of the solar light receiving surface of the solar cell module cannot be adjusted, it may not be able to sufficiently receive sunlight and may not be able to generate power efficiently. Moreover, since the structure which supports a solar cell module and a ventilation louver above the ventilation opening part of a ridge is complicated, construction is difficult.

  Hereinafter, an embodiment according to the present invention will be described with reference to the drawings. As shown in FIG. 1, the building ventilation apparatus 1 concerning this embodiment is installed in the building b of the roof a, the canopy part 2 which covers the upper part of the ventilation opening c of the building b, and a canopy part Support leg 3 which supports 2 on the roof a, and a ventilation fan 4 which performs forced ventilation of the attic d through the ventilation opening c.

  The roof a includes a base plate e, a base material f stretched on the base plate e, and a tile g laid on the base material f. The ventilation opening c is formed by cutting out a part of the butting top of the field board e and communicates with the attic d. Around the ventilation opening c, rainwater intrusion prevention plates h and h are provided. The rainwater intrusion prevention plate h is formed by bending a plate material into a U shape, and one end side is fixed between the base material f of the roof a and the roof tile g, and the other end side of the left and right roofs a and a. It stands up vertically from the edge and prevents rainwater from entering the attic d from below the building ventilation device 1.

The canopy portion 2 is composed of a base material 6 having a mountain-like cross-sectional view having inclined surfaces on the left and right sides, and a solar cell module 5 installed on the surface of the base material 6.
The substrate 6 is formed of a steel plate having weather resistance suitable for outdoor use, and is inclined at a predetermined inclination angle θ with respect to the horizontal plane H. The inclination angle θ is 20 ° <θ <40 °, and particularly preferably 30 °. In this example, the inclination angle θ is 30 °. The left and right ends of the base 6 are bent downward to prevent rainwater from entering the building ventilation device 1. A wiring box 7 for the solar cell module 5 is attached to the back side of the base 6.
The solar cell module 5 is installed on an inclined surface on the surface of the base 6 where the amount of solar radiation is large with the sunlight receiving surface 51 facing upward. The type of the module may be any type such as a crystal type or an amorphous type, but it is preferable to use a sheet in which an amorphous sheet that is easy to adjust to the dimensions of the substrate 6 and is lightweight is bonded to a steel plate.

  The ventilation fan 4 is suspended from the butt top of the base 6 and is disposed above the ventilation opening c. And the ventilation fan 4 is connected with the electric wire taken out from the wiring box 7, and becomes a structure which act | operates with the direct current supplied from the solar cell module 5.

The support leg 3 includes a roof support member 8 fixed to the roof a and a canopy support member 9 fixed to the canopy portion 2.
The roof supporting member 8 bends one end portion of the plate material into a substantially L shape so as to follow the side surface of the through plate i and the surface of the roof tile g to form a fixed portion 81 fixed to the roof a, and the other end portion. The fixing portion 81 is bent at a substantially right angle in the opposite direction to form a shaft portion 82 at the tip thereof, and the fixing portion 81 is fixed to the through plate i of the roof a with the bolt 11.
The canopy support member 9 is formed by forming a bearing 91 having a C-shaped cross section at one end of a plate material, and a ventilation slit 92 communicating with the ventilation opening c is provided on the plate surface. The bearing 91 is connected to the shaft 82 so as to be relatively rotatable, and constitutes the hinge 10. The end opposite to the bearing 91 is fixed to the back surface of the canopy 2.

The building ventilation apparatus 1 concerning this embodiment is comprised as mentioned above, and demonstrates the effect | action below. In the building ventilation apparatus 1 according to the present embodiment, the support leg 3 includes a roof support member 8 fixed to the roof a and a canopy support member 9 fixed to the canopy portion 2. Since the canopy support member 9 is connected to the canopy 10 via a hinge 10, the roof support member 8 is fixed to the roof when installed on a steep roof as shown in FIG. After the inclination angle of the canopy support member 9 with respect to the roof support member 8 is adjusted by the hinge 10, when the hinge 10 is fixed with a fixture such as a clamp (not shown), the solar light receiving surface 51 of the solar cell module 5 is fixed. The canopy 2 can be supported in a state where it is inclined by 30 ° with respect to the horizontal plane H.
Similarly, when installed on a roof with a gentle slope, if the inclination angle of the canopy support member 9 with respect to the roof support member 8 is adjusted in the direction opposite to that in FIG. The canopy 2 can be supported in a state where is tilted by 30 ° with respect to the horizontal plane H. In other words, the solar light receiving surface 51 of the solar cell module 5 can be arranged at an optimum angle with respect to the horizontal plane H regardless of the slope of the roof a. As a result, the power generation efficiency can be improved, and larger power can be obtained.

  Moreover, since the hinge 10 connects the shaft 82 and the bearing 91 so as to be relatively rotatable, the inclination angle of the sunlight receiving surface 51 with respect to the horizontal plane H can be adjusted steplessly to an arbitrary angle. Further, since the angle adjusting means is constituted by the hinge 10, the structure can be simplified and the manufacturing cost can be suppressed.

  Furthermore, since the electricity generated by the solar cell module 5 is fed to the ventilation fan 4 through the electric wires, the attic can be well ventilated without applying an electricity bill. Moreover, it is not necessary to wire the ventilation fan 4 from the indoor power supply, and the workability is excellent. Moreover, since the ventilation fan 4 rotates, the hot air and moisture in the attic are forcibly discharged to the outside through the ventilation slit 92, so that it is possible to effectively prevent the hot air and moisture from being accumulated in the attic.

  Moreover, after fixing one end part of the support leg 3 to the roof a, the ridge ventilation apparatus 1 is attached to the ridge part b of the roof a only by attaching the canopy part 2 to the other end part of the support leg 3. Because it can be installed in a machine, it has excellent workability and can reduce the burden on the operator. In addition, as described above, the inclination angle of the solar light receiving surface 51 of the solar cell module 5 can be set to an optimum angle regardless of the slope of the roof, so that the solar cell module 5 can be installed on an arbitrary roof and is excellent in versatility.

  The building ventilation device 1 is not limited to the illustrated embodiment. For example, the base material 6 may not have a cross-sectional mountain shape having inclined surfaces on the left and right, and may be any shape as long as the solar light receiving surface 51 of the solar cell module 5 can be disposed so as to receive sunlight. Therefore, for example, a single-flow inclined surface shape or a flat plate shape arranged in the horizontal direction may be used. Further, the angle adjusting means may not be the hinge 10 and may be any configuration that can set the inclination angle of the solar light receiving surface 51 of the solar cell module 5 to an optimum angle. Further, the roof support member 8 and the canopy support member 9 are formed of a plate material having substantially the same width as that of the canopy portion 2. However, the present invention is not limited to this. A plurality of them may be arranged at predetermined intervals.

  Moreover, the fixing structure with respect to the roof a of the fixing part 81 is not limited to the above-described embodiment. It may be a structure fixed with. If it does in this way, since support leg 3 can be fixed to roof a outside the canopy part 2, attachment work will become easy. In this case, since the fixing part is not covered with the canopy part 2, it is preferable to perform waterproofing or rustproofing.

  Further, the prevention of rainwater intrusion into the attic is not limited to the provision of the rainwater intrusion prevention plate h in the ventilation opening c. For example, a louver-shaped rainwater intrusion prevention member is provided in the rainwater intrusion path or has air permeability. A foam may be provided.
