Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar cell ventilation device. More specifically, the present invention relates to a roof ventilator using a standard module solar cell, which is excellent in waterproofness, workability, and economy.

[0002]

2. Description of the Related Art Conventionally, the use of a solar cell as a power supply source for a ventilator has been studied with the expectation of developing a solar cell and expanding its application. As for use in this ventilation device, for example, as shown in FIG. 6, the power from the solar cell tile (a) installed on the roof surface (a) is supplied to the fan () of the ventilation device (c) for indoor ventilation. D) A system used as a driving power source is known.

[0003]

However, in practice, in the case of this conventional ventilation device, the solar cell (a) part and the ventilation device (c) part are separate bodies, so they are separated from each other. It had to be constructed, which was troublesome and not easy to construct. Moreover, it was not unthinkable to integrate this, but in the studies so far, the integration of the solar cell and the ventilation device is inevitably strong as a custom-ordered product, its structure is expensive, and construction is easy. Was not good, and there was a problem in the waterproof performance for the roof ventilation device.

For this reason, it has been the actual situation that a ventilation device with a built-in solar cell, which requires less construction, is economically advantageous, and does not impair the waterproof performance in a rooftop scene, has not yet been realized. Therefore, an object of the present invention is to solve the drawbacks of the conventional techniques as described above, and to provide a new solar cell ventilation device which is excellent in workability and economical efficiency and has a good waterproof performance.

[0005]

The present invention is to solve the above-mentioned problems by providing a ventilation device including a ventilation device main body portion installed on a roof surface and a main body cover portion having a solar cell attached to the ventilation device main body portion. Therefore, the main body part has a draining part and a water receiving part together with a ventilation fan, and the exhaust port part is formed on the periphery by attaching the main body cover part equipped with the solar cell module to the top part. A characteristic solar cell ventilation device is provided.

[0006]

In the ventilator of the present invention, since the solar cell is provided on the top of the cover in the structure including the main body and the cover, it is possible to integrate the solar cell of the standard module into the ventilator. , Saves construction work and is highly economical. Further, in this ventilation device, since the water draining portion and the water receiving portion are provided in the main body portion in advance, the roof ventilation device also has excellent waterproof performance.

Hereinafter, the solar cell ventilation device of the present invention will be described in more detail with reference to the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a sectional view showing an example of a solar cell ventilation device of the present invention. For example, as illustrated in FIG. 1, the solar cell ventilation device of the present invention is installed as a flat-field ventilation device on the installation surface of the roof plate (1) and roof tiles (2). The ventilation device is composed of a ventilation device main body part (3) attached and installed on the roof surface and a main body cover part (4) attached to this. The standard module solar cell (41) is provided on the top of the main body cover (4).
Are attached using the cover body (42) and the silicone resin (43). When a standard module solar cell is installed on a roof tile or the like, the appearance is inevitably impaired, but by installing it on the main body cover (4) of the ventilation device as in the present invention, the appearance becomes a problem. It is possible to improve workability and economy.

Further, the main body cover portion (4) can be appropriately provided with a louver portion (44) for an exhaust port and a cut-and-raised portion (45) for preventing water from entering. The cut-and-raised parts (45) are effective for improving the waterproof performance of the ventilation device. Then, the main body cover part (4) is provided with a mounting screw (4
Attach it to the ventilator body (3) according to 6). By this attachment, an exhaust port portion (5) is formed at the peripheral edge of the ventilation device.

The ventilation device body (3) includes a ventilation fan (3
1) together with the drainer (32) and the water receiver (3
3). The ventilation fan (31) of these is
Electric power from the solar cell (41) is received through the lead wire (6) and the waterproof connector (7) and driven by this. This ventilation fan (31) can be a single or a plurality. More preferably, the plurality of ventilation fans (31) are alternately switched and used so as to cope with a change in electromotive force of the solar cell (41) due to irradiation of sunlight. By this, effective use of electric power,
The durability of the ventilation fan (31) is improved.

Drainer (32) and water receiver (33)
The shape and arrangement of may be appropriate, and these may be integrated in their functions. Along with the cut-and-raised part (45), the draining part (32) and the water receiving part (33).
Due to the existence of the above, the waterproof performance of the ventilation device of the present invention installed on the roof flat scene becomes good.

FIG. 2 shows an example of the appearance of the solar cell ventilation device of the present invention having the above structure and shape. The standard module solar cell (41) is arranged together with the cover body (42) on the top, and the exhaust port (5) is arranged on the periphery. Then, the main body cover portion (4) as described above is attached and fixed to the main body portion (3) by the attaching screw (46).

FIG. 3 is a plan view showing a state in which the main body cover portion (4) is removed. For example, this Figure 3
As illustrated in FIG. 2, the ventilation fans (31) can be arranged as a set of two ventilation fans (31) as a total of four axial fans. In each set, a short path is prevented by the airflow control partition plate portion (8). Then, as shown in an enlarged view (A) showing a state where the partition plate is removed, the air flow control partition plate portion (8) is provided with a voltage control circuit and the number of ventilation fans (31) that operate according to the amount of solar radiation. A control circuit unit (9) such as a circuit for changing from two to four is arranged.

When the number of ventilation fans (31) that operate according to the amount of solar radiation is changed by the control circuit, the air flow control partition plate section (8) is short-circuited between the ventilation fans that do not operate and the ventilation fans that operate. Because a pass occurs,
It plays a role of preventing this short pass.
Then, in the ventilation device of the present invention that ventilates by such a controlled ventilation fan (31), it is effective to devise the formation of the exhaust port portion (5).

That is, the exhaust port portion (5) illustrated in FIGS. 1 and 2 is preferably arranged on the left and right sides and the front side with respect to the roof inclination. As a result, by arranging them on the left and right, as shown in FIG. 4, the wind from the side escapes in the opposite direction by the wind pressure. Further, as illustrated in FIG. 5, the wind from the front exits from the left and right exhaust port portions (5) due to the presence of the airflow control partition plate portion (8).

For this reason, the outside air does not disturb the indoor exhaust air by the ventilation device of the present invention. Ventilation performance will be good. Of course, the present invention is not limited to the above examples. Needless to say, various structures and shapes can be used for the details.

[0017]

Industrial Applicability According to the present invention, a roof ventilator integrated with a solar cell equipped with a solar cell of a standard module is realized.
Furthermore, it becomes a ventilation device with good waterproof performance.
