In addition, although the general drainage similar to what is used when installing the conventional natural ventilation type | mold ventilation building can be used for this drainage 16, only the area where the ventilation fan 30 is installed is drained 16 Therefore, in order to compensate for the decrease, it is preferable to increase the opening area of the drainage drain 16 by the installation area of the blower fan 30 as compared with the case of the natural ventilation type ventilation building. Thereby, even if it is only the case of ventilation by natural ventilation in the state where the ventilation fan 30 does not operate, the ventilation performance equivalent to the conventional natural ventilation type ventilation building can be exhibited.

The forced exhaust type ventilation ridge 20 includes a pair of symmetrical ventilation bodies 21 and a pair of ventilation covers 22, respectively. The upper part of the drainage 16 is covered with the ventilation body 21, and the upper part of the ventilation body 21 is covered with the ventilation cover 22. Thus, a ventilation path A is formed between the ventilation main body 21 and the ventilation cover 22, and indoor air is discharged from the exhaust port 60.
The blower fan 30 is disposed in the field opening 15, and the blower fan 30 is driven by the solar cell module (power source) 40 disposed on the upper surface of the ventilation cover 22. The solar cell module 40 and the blower fan 30 are directly connected by the wiring 50. By providing the solar cell module 40, the indoor air can be forcibly discharged by forced ventilation by the blower fan 30 in a time zone where sunshine is obtained, which is particularly effective in a state where the outside air temperature is high such as in summer. .

As shown in FIGS. 4A and 4B, the solar cell module 40 is attached to one of the pair of ventilation covers 22 and has a wiring 52 on the solar cell module 40 side of the wiring 50. The wiring 52 has one end connected to the solar cell module 40 and the other end provided with a connector 52a. The connector 52a is connected to the connector 51a on the blower fan 30 side shown in FIG.

As shown in FIG. 4 (c), the ventilation main body 21 includes a pair of bottom surface plate materials 21a arranged to be inclined along the field plate 13, and a bottom surface opening formed at an upper end portion of the pair of bottom surface plate materials 21a. A body 21b, an upper rising plate 21c that is erected at the upper end of the bottom plate 21a, and a lower rising plate 21d that is erected at the lower end of the bottom plate 21a, It is attached to the top of both flow roofs via a fixture (angle member) 17. The upper side rising plate member 21c is located between the upper side end portion of the bottom plate member 21a and the bottom opening 21b.
The ventilation main body 21 includes a ventilation cover fixing tool 21f provided with a hole for a screw 70 for fixing the ventilation cover 22 to the ventilation main body 21, and a ventilation cover fixing for holding the ventilation cover fixing tool 21f on the ventilation main body 21. A tool holding member 21g and a partition plate 21h are provided. The ventilation cover fixture 21f is U-shaped with an opening on the lower surface side, and is disposed over the entire length in the longitudinal direction of the ventilation main body 21. The upper surface provided with a hole for the screw 70 is in close contact with the ventilation cover 22, and the side surface The lower end and the bottom plate member 21a have a predetermined interval. The ventilation cover fixing member holding member 21g is disposed at two left and right sides of the ventilation main body 21 in the longitudinal direction with the partition plate 21h interposed therebetween, and supports the ventilation cover fixing member 21f at a total of eight points. The partition plate 21h is provided over the entire length in the longitudinal direction of the ventilation main body 21 at the center in the short direction of the ventilation cover fixture 21f, and the upper end thereof and the ventilation cover 22 have a predetermined interval.
A cutout groove 21e having a U-shaped cross section is formed on the upper surface of the ventilation cover fixture holding member 21g on the side where the solar cell module 40 is provided. The diameter of the notch groove 21e is substantially the same as the diameter of the wiring 52. By arranging the wiring 52 in the notch groove 21e, the wiring 52 can be pulled out to the blower fan 30 side without bypassing the ventilation cover fixing tool 21f. Moreover, the wiring 52 can be clamped by the notch groove 21e by making the diameter of the notch groove 21e substantially the same as the diameter of the wiring 52.

The ventilation cover 22 on which the solar cell module 40 is provided is provided with a hole 22a through which the wiring 52 passes. The lower end of the ventilation cover 22 extends beyond the lower side rising plate member 21d, and the hole 22a is provided at a position extending beyond the lower side rising plate member 21d.
Although caulking or the like is preferably applied to the opening gap of the hole 22a in which the wiring 52 is disposed in order to prevent rainwater intrusion, the hole 22a through which the wiring 52 passes as described above passes over the upper side of the lower rising plate member 21d. By providing at the extended position, even if rainwater enters from the hole 22 a, the rainwater is drained from the exhaust port 60, so that the rainwater entering from the hole 22 a passes through the field opening 15 of the building 10. Intrusion into the inside can be prevented.

  The cutout groove 21e of the ventilation body 21 is formed so as to be shifted laterally from the position where the hole 22a is provided so as not to overlap the hole 22a of the ventilation cover 22. If there is no allowance for the length of the wiring 52, it becomes difficult to connect the connector 52 a of the wiring 52 and the connector 51 a of the wiring 51, and to attach / remove the ventilation cover 22 to the ventilation main body 21. It is preferable to provide a margin. However, if the length of the wiring 52 is increased, the wiring 52 is likely to interfere with other members, so that the notch groove 21e is shifted by a predetermined distance instead of directly below the hole 22a as in this embodiment. By forming the wiring 52 at the position, the wiring 52 can be accommodated without interfering with other members even when the wiring 52 has a sufficient length.

FIG. 5 is a view showing a blower fan of a forced exhaust type ventilation building according to an embodiment of the present invention, in which FIG. 5 (a) is a plan view, FIG. 5 (b) is a left side view, and FIG. It is a rear view.
An axial fan is used as the blower fan 30, and a housing 32 that supports the fan motor unit 31, a pair of attachment pieces 33 that extend from the housing 32, and a pair that is formed by folding back from the end portions of the attachment pieces 33. Engaging piece 34.
Further, the blower fan 30 has a wiring 51 on the blower fan 30 side of the wiring 50. One end of the wiring 51 is connected to the fan motor unit 31, and the other end includes a connector 51a. The connector 51a is connected to the connector 52a on the solar cell module 40 side. Thus, by directly connecting the blower fan 30 and the solar cell module 40 with the connectors 51a and 52a, the blower fan 30 can be driven by solar energy without using a battery or a base.
The substantially cylindrical fan motor unit 31 has a plurality of blades 35 attached thereto, and is fixed to the housing 32 via three support members 36 arranged at equal intervals on the upper surface side. The support member 36 has one end connected to the fan motor unit 31 and the other end connected to the housing 32. The height position of the upper surface 31a of the fan motor unit 31 may be equal to or less than the height position of the upper surface 32a of the housing 32. However, in the present embodiment, both heights are the same. One of the three support members 36 is a hollow support member 36a having a hollow inside, and one end of the wiring 51 is connected to the fan motor unit 31 through the inside of the hollow support member 36a.

The blower fan 30 is installed in the drainage 16 by fitting a pair of drainage folding plates 16c between the attachment piece 33 and the engagement piece 34 (see FIG. 4D). Since it can fix by inserting a pair of draining cut folding plate 16c between the attachment piece 33 and the engagement piece 34, the ventilation fan 30 does not shift | deviate by a vibration or an air current. The blower fan 30 is attached so that its axis is perpendicular to the opening surface of the field opening 15. Since the height position of the upper surface 31a of the fan motor unit 31 and the height position of the upper surface 32a of the housing 32 are the same, the fan motor unit 31 is installed in the draining drain 16 while the It does not protrude upward from the upper end (see FIGS. 1 to 3).
In this manner, the blower fan 30 can be installed using the conventional drainer 16, so there is no need to newly provide a mounting member. Moreover, since the ventilation fan 30 is installed in the draining drain 16, it can be provided separately from the ventilation main body 21, and the height of the forced exhaust type ventilation building 20 can be lowered to improve the design. In addition, by making the blower fan 30 independent of the ventilation main body 21, the replacement and maintenance of the blower fan 30 is facilitated as compared with the case where the blower fan 30 and the ventilation main body 21 are integrated.
In addition, in a state where the blower fan 30 is installed at the drainage drain 16, the fan motor unit 31 does not protrude upward from the upper end of the drainage cut-up plate 16b, so that the blower fan 30 and the ventilation main body 21 do not interfere with each other. As shown in FIG. 2 or FIG. 3, even if the roof slope of the building 10 changes, a ventilation building corresponding to the slope can be installed.
Note that the blower fan 30 may be disposed close to one end of the drainage drain 16 as shown in FIG. 4 (d), but it is more preferable from the viewpoint of ventilation to be disposed at the center of the drainage drainage 16. .

According to the present embodiment, since the blower fan 30 is installed using the drainer 16, there is no need to newly provide a mounting member. Moreover, since the ventilation fan 30 is installed in the draining drain 16, it is not necessary to provide integrally with the ventilation main body 21, and the height of the whole ventilation building can be made low and design can be improved. In addition, by making the blower fan 30 independent of the ventilation main body 21, the replacement and maintenance of the blower fan 30 is facilitated as compared with the case where the blower fan 30 and the ventilation main body 21 are integrated.
In addition, it was difficult to cope with the gradient with the conventional fan fan 30 and the ventilation wing integrated, but the fan fan 30 was separated from the ventilation body 21 and installed in the draining drain 16 and installed in the draining drain 16. In the state, by preventing the fan motor unit 31 from protruding upward from the upper end of the draining and raising plate 16b, the blower fan 30 and the ventilation body 21 do not interfere with each other, and the roof slope of the building 10 changes. Ventilation building corresponding to the gradient can be installed.
Further, the hole 22a is provided at a position extending beyond the upper side of the lower rising plate member 21d, so that the hole 22a for passing the wiring 52 is provided at a position extending beyond the upper side of the lower side rising plate material 21d. Thus, even if rainwater enters from the hole 22 a through which the wiring 52 passes, the rainwater can be prevented from entering the inside of the building 10 from the field opening 15.
Further, the solar cell module 40 is disposed on the upper surface of the ventilation cover 22, and the solar cell module 40 and the blower fan 30 are connected by the wiring 50, so that the forced exhaust type ventilation building 20 can be connected without connecting to a household power source or the like. Since the blower fan 30 can be driven independently, ventilation using both natural ventilation and forced exhaust can be performed.

In this embodiment, the ventilation main body 21 includes a pair of bottom surface plate materials 21a, forms a bottom surface opening 21b between the pair of bottom surface plate materials 21a, and attaches the ventilation main body 21 to the ridge top of the double-flow roof. The forced exhaust type ventilation building 20 corresponding to the roof has been described. However, if only one of the bottom plate 21a and the ventilation cover 22 is provided, the forced exhaust type ventilation building 20 corresponding to the single-flow roof can be obtained.
Moreover, although the present Example demonstrated using the solar cell module as the power supply 40, you may use an indoor power supply.
Moreover, although the forced exhaust type ventilation building 20 in the present embodiment has been described as including the ventilation main body 21 and the ventilation cover 22, the ventilation cover 22 is not necessarily required if the ventilation path A is formed in the ventilation main body 21. And not.

  The forced exhaust type ventilation building of this invention can install a ventilation fan, without providing the member for attachment newly, is excellent in maintainability, and can respond to the different gradient of a roof top part.
