Description

  The present invention relates to a ventilation building that is installed on a roof and ventilates indoor air and outdoor air, and uses a fan operated by a solar cell module to increase the ventilation amount.

In a conventional ventilation building, indoor air is discharged from the opening of the roof by natural ventilation, and outdoor air is allowed to flow. This natural ventilation was performed by utilizing the upward movement of warm indoor air.
In order to increase the ventilation amount of such a ventilation building, a fan using a solar cell module may be used. (For example, refer to Patent Document 1).
There is also a prior art in which the fan is disposed at a position where it is hung from the ventilation building to increase the ventilation amount. (For example, see Patent Document 2)

Ventilation ridges 101 and 201 using a solar cell module fan according to the prior art will be described.
FIG. 7 is a prior art related to Patent Document 2, in which a ventilation fan 101 is attached in a state in which a ventilation fan 102 that is rotated by a solar cell module (not shown) is suspended indoors from a ventilation port 103. It is.
However, there are cases where a building or house where a ventilation building is installed is a joint portion of each field plate, and a purlin is attached to the top of the roof. If there is this purlin, if the ventilation ridge 101 is suspended from the ventilation port 103, it cannot be suspended in contact with the purlin, and the fan cannot obstruct the indoor air due to obstruction. Even if there is no purlin, since the fan 102 is installed on the indoor side of the house from the ventilation building 101, the indoor air sent out by the fan 102 does not pass through all the ventilation openings 103, and the ventilation efficiency is lowered.
Therefore, there is a need for a ventilation building equipped with a solar cell module fan installed at a position where ventilation can be appropriately performed even if there is a purlin.

8 is a prior art according to Patent Document 1, and a ventilation fan 202 is installed inside a building ventilation device 201. The fan 202 is rotated by a solar cell module 203. It moves.
However, the axis of the fan 202 is oriented in a direction perpendicular to the ventilation direction, and ventilation by rotation of the fan 202 may be ventilated in the opposite direction. In addition, since the fan 202 is suspended from the top of the ventilation building, it is directly affected by ventilation from both sides of the house, which is not safe for installation.
Therefore, there is a need for a ventilation fan that uses a solar cell module to appropriately promote ventilation, and that the installation is strong and easy to install.

Japanese Patent Laying-Open No. 2006-322218 (first page, FIG. 1) JP 2001-349027 A (first page, FIG. 1)

In the invention according to Patent Document 1, the axial direction of the fan is a direction orthogonal to the inflow and outflow directions of indoor air and outdoor air from the roof opening. Use of this axial fan may hinder indoor air exhaust and outdoor air inflow, and the ventilation rate cannot be increased.
Further, the invention according to Patent Document 2 arranges the fan at a position suspended from the roof opening to the roof side, and not only is the fan difficult to support, but the indoor air outflow by the fan is not necessarily the roof. Not done from the opening.

On the other hand, it is necessary to install an axial fan inside the ventilation building so that the contractor can easily perform the construction, and to place the axial flow fan in the vicinity of the roof opening so as to perform efficient ventilation.
Moreover, there has been a demand for a ventilation building in which a fan and a solar cell module can be easily installed even if the contractor does not have knowledge of electricity by incorporating the fan and the solar cell module into the ventilation building.

  Therefore, in the ventilation building using the fan by the solar cell module according to the present invention, in the ventilation building installed on the roof while covering the opening, the opening in the top of the roof, An axial fan having an axial direction perpendicular to the opening surface of the opening is provided at a position above the opening.

  Moreover, it is preferable to rotate an axial fan with a solar cell module.

  The axial fan is attached to the substrate. The fan is attached to the upper surface of the aperture surface after opening the substrate, and the fan is opened in the direction perpendicular to the upper surface of the substrate. Preferably, the air hole is formed with a vent hole but no fan attached.

  In addition, each side edge of the board has an extended and bent mounting surface, and the ventilation building is located above the roof of the roof of the basement plate and tile near the top of the mountain roof of the building to be installed. It is preferable that a barrier wall is disposed inside the ventilation building at positions above both sides of the roof opening, and the substrate is fixed by attaching a mounting surface to the surface of the barrier opening on the roof opening side. .

  Moreover, it is preferable that the light-emitting body which emits light by the power source from the solar cell module is attached inside the ventilation building and in the vicinity of the outlet of the ventilation building.

According to the present invention, it is possible to provide a ventilation building with high ventilation efficiency by forcibly discharging indoor air by forced ventilation using an axial fan. Moreover, since the ventilation holes are provided in addition to the axial flow fan, not only ventilation by the fan but also ventilation by natural ventilation can be performed together.
This can be ventilated by a fan during the daytime when the solar cell module is operating, and is due to natural ventilation during a time zone when the solar cell module is not operating such as at night. At night, there is an effect that noise caused by the rotation of the fan is eliminated.
In addition, in winter when the solar energy is relatively low, the specific gravity of the indoor air becomes lighter due to indoor heating, etc., so the need for forced ventilation by the fan is reduced, while the summer energy when the solar energy is relatively high For example, the specific gravity of indoor air becomes heavy due to indoor cooling, and natural ventilation does not work sufficiently, so the need for forced ventilation by fans increases. Therefore, the ventilation efficiency of the ventilation building can be increased by combining the forced ventilation of the fan proportional to the solar energy and the natural ventilation.

Moreover, since the fan and the solar cell module are attached to the inside of the ventilation building, the construction can be easily performed even if the contractor does not have knowledge of electricity.
That is, since the fan and the ventilation hole are attached to and formed on the substrate, the construction can be easily performed simply by attaching the substrate to the ventilation building. Further, the substrate can be firmly fixed by the method of fixing the substrate by attaching the mounting surface of the substrate to the inside of the ventilation building, that is, the blocking wall of the ventilation building.
In addition, by attaching a light emitter that emits light from the power source from the solar cell module, it can be confirmed that the solar cell module is operating from the outside. You can check the operating status without dismantling. Moreover, since it is attached to the inside from the discharge port, it is possible to avoid damage caused by rain winds and floating substances as much as possible.

Moreover, the ventilation efficiency by a fan can be raised by arrange | positioning a fan to the ventilation path near a roof opening part, and also locating the axis | shaft of an axial flow fan in the same direction as the ventilation direction.
That is, since the ventilation building is scheduled to be discharged and flow into the outside air through the roof opening and the ventilation path, it is preferable to install a fan in the ventilation path in terms of improving ventilation efficiency. Moreover, it is most necessary for ventilation to exhaust indoor air from the roof opening, and the axial direction of the axial fan above the roof opening is perpendicular to the opening surface of the opening. In the vicinity, the path through which indoor air is ventilated coincides with the axial direction of the axial fan. This makes it possible to efficiently ventilate indoor air using the property of generating an axial pressure in the axial direction of the axial fan.

BEST MODE FOR CARRYING OUT THE INVENTION A best mode for carrying out a ventilation building using a fan by a solar cell module according to the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view showing an example of a ventilation building 1 according to this embodiment, and FIG. 2 is a cross-sectional view showing a conventional ventilation building using a solar cell module without a fan. 3 and 4 show the substrate 22 according to the present embodiment, FIGS. 5 and 6 are perspective views of the entire ventilation building 1 according to the present embodiment, and FIGS. 7 and 8 are sectional views showing the prior art of the present invention.

The ventilation building 1 which concerns on a present Example is demonstrated.
As shown in FIG. 1 and FIG. 5, the ventilation building 1 is installed on the upper side of the opening 4 formed by moving the building base plate 2 and the roof tile 3 obliquely downward from the top of the roof. The ventilation building 1 is formed by combining the outer surface portion 11, the outer blocking walls 12, 12, and the inner blocking walls 13, 13. The outer surface 11 has a mountain shape on the upper surface, and a plurality of second discharge ports 16 and 16 are formed on both sides thereof. The outer blocking walls 12 and 12 are plate-shaped bent four times, and are categorized as 12a, 12a, upper surface joining portions 12b, 12b, second outlet blocking portions 12c, 12c, first outlet portions 12d, 12d, It consists of lower surface bonding portions 12e and 12e. The inner blocking walls 13 and 13 are plate-shaped and bent twice, and are composed of a caulking portion 13a and 13a, an opening blocking portion 13b and 13b, and a lower surface joining portion 13c and 13c.

  The ventilation building 1 is formed by these combinations. That is, the upper surface joining portions 12b and 12b of the upper shielding walls 12 and 12 are joined to the inner upper surface of the outer surface portion 11, and the lower surface joining portions 12e and 12e of the upper shielding walls 12 and 12 are joined to the inner lower surface of the outer surface portion 11, respectively. . Then, the lower surface joining portions 13 c and 13 c of the lower blocking walls 13 and 13 are joined to the inner lower surface of the outer surface portion 11. The ventilation building 1 which concerns on a present Example is formed by these joining. The joining method is screwing (not shown), but there is also a method such as welding.

  By the above combination, the ventilation path 15 is secured between the outer surface portion 11 and the outer blocking walls 12 and 12 and the inner blocking walls 13 and 13. Then, the first discharge ports 14 and 14 are formed by opening a plurality of holes in the first discharge port portions 12d and 12d of the outer blocking wall. Also, a plurality of openings are formed on both sides of the outer surface of the outer surface portion 11 to form second discharge ports 16 and 16. The second discharge ports 16 and 16 are the final discharge ports.

  As shown in FIG. 2, the ventilation building 1 was originally performed by natural ventilation. Natural ventilation is performed using the fact that the indoor air a, which is indoor air, is warmed and the specific gravity is reduced. The indoor air a enters the ventilation path 15 inside the ventilation building 1 through the opening 4 opened at the top of the roof, passes through the first outlets 14 and 14, and the second outlets 16 and 16, and is discharged outside. The In this embodiment, as shown in FIG. 1, a ventilation fan 21 is attached to increase the ventilation efficiency from natural ventilation, and the indoor air b is performed by forced ventilation.

A ventilation fan 21 is installed in the ventilation building 1 according to the present embodiment. As shown in FIG. 3, the ventilation fan 21 is attached to the substrate 22 at a plurality of locations. The board | substrate 22 is a rectangular board and the ventilation hole 23 is opened. The vent hole 23 is a substantially rectangular opening, and 2 × 2 holes are formed as one set and are formed in the central portion and both side portions of the substrate 22. And the ventilation fan 21 is attached by making a comparatively big round hole in the position between the ventilation hole 23 of the board | substrate 22 center part, and the ventilation hole 23 of a both-sides part. As shown in FIG. 4, the ventilation fan 21 is attached by being screwed with four screws 17 for each ventilation fan 21 from the bottom side.
It should be noted that the number of ventilation fans 21 attached, the number of ventilation holes 23, and the shape are appropriately changed depending on the size of the ventilation building 1 installed, the size of the substrate 22, and the length.

The ventilation fan 21 uses an axial fan. The shaft of the axial fan is attached so as to be in the same direction as the vertical direction of the substrate plane. Moreover, as shown in FIG. 4, the control board 25 is attached to the ventilation fan 21, and the solar electric energy from the solar cell module 5 is conducted to the control board 25 and the ventilation fan 21 through the conductive wire 18, The ventilation fan 21 is rotated.
As shown in FIGS. 1 and 5, the solar cell module 5 is a small panel-like module and is attached to the outside of the outer surface portion 11 of the ventilation building 1. The solar cell module 5 is attached by four screws 17 on one slope of the outer surface portion 11 having a mountain shape and slopes on both sides. As shown in FIG. 1 and FIG. 6, current is sent from the solar cell module 5 to the ventilation fan 21, and the light-emitting diode 6 that is a light emitter to be issued when the solar cell module 5 is in operation is disposed outside the ventilation building. It attaches toward the 2nd discharge port side of the 2nd discharge port blocking part 12c of the outer side blocking wall 12 of the blocking wall 13, 12c.
Thereby, the ventilation building 1 using the solar cell module 5 can be used in combination, and can be installed as one, so that it is possible to easily install even if the contractor does not have knowledge of electricity. . Further, since the light emitting diode 6 is attached, it is possible to confirm the operating state from the outside and the second discharge port 16.

As shown in FIGS. 3 and 4, the substrate 22 has a rectangular plate shape. However, as shown in FIG. 1, the both sides are extended and bent to form mounting pieces 24 and 24, respectively. The bending direction of the mounting pieces 24, 24 is such that the opening blocking portions 13b, 13b of the inner blocking walls 13, 13 are slightly inclined from the vertical direction toward the inside of the ventilation building, and coincide with this inclination angle. That is, in order to prevent moisture such as rain from entering the indoors when outside air flows into the front end portions of the inner blocking walls 13 and 13, there are provided caches 13 a and 13 a, and an opening is provided to prevent this inflow. The blocking portions 13b and 13b are slightly inclined toward the inside of the ventilation building. In order to attach the substrate 22 to the inclined opening blocking portions 13b and 13b and keep the substrate in the horizontal direction, the mounting pieces 24 and 24 of the substrate 22 also have the same angle as the inclined direction of the opening blocking portions 13b and 13b. It is tilted. Then, the mounting pieces 24, 24 and the opening blocking portions 13b, 13b are fixed by screws (not shown).
As a result, when the substrate 22 is attached, the substrate 22 is positioned in the same horizontal direction as the opening surface of the opening 4, and the ventilation fan 21 having an axial direction perpendicular to the substrate is Thus, it has an axial direction in the vertical direction.

By attaching to such a position, the ventilation of the ventilation fan 21 attached to the substrate 22 can be efficiently increased.
In other words, ventilation by the ventilation building 1 has been naturally ventilated by providing an opening at the top of the roof by utilizing the rise of warm indoor air with light specific gravity. Ventilation is possible. In addition, the presence of the ventilation fan 21 immediately above the opening 4 leads to sucking up the indoor air flowing into the opening immediately after the action of the ventilation fan 21, thereby enabling efficient ventilation.
And since the ventilation fan 21 is attached to the ventilation building 1, when a contractor constructs, it becomes possible to construct easily.

And the ventilation by the ventilation building 1 illustrated here is characterized by using the forced ventilation by the ventilation fan 21 and the natural ventilation by the ventilation hole 23 together.
That is, by using the solar cell module 5, forced ventilation is performed by turning the ventilation fan 21 by sunlight energy in the daytime. By performing natural ventilation at night when the sun is not exposed, there is no noise due to the rotating sound of the ventilation fan 21, and a calm residential space can be provided.
In addition, the conventional ventilation building naturally ventilates by taking advantage of the fact that the warm air in the indoor lightens and rises, but this is effective when the temperature of the indoor air is higher than the outside air, such as in winter or at night. It is. On the other hand, when the temperature of the indoor air becomes lower than the outside air due to the use of cooling, such as in the summer or in the daytime, natural ventilation cannot provide sufficient ventilation. Therefore, it is necessary to perform forced ventilation using a ventilation fan with a solar cell module in the summer or when the daytime solar energy is strong.
As described above, the ventilation building 1 exemplified here can selectively use forced ventilation and natural ventilation, and can improve ventilation efficiency.
