Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ventilation fan using a solar cell.

[0002]

[Prior Art]

 In recent years, due to global environmental issues, great expectations have been placed on solar cells that are installed outdoors to generate photovoltaic power. As a familiar application, the idea of installing a solar cell on the roof of a building and using the generated power to cover the daytime power consumption has been proposed and partially implemented.

On the other hand, at present, the power supply of the ventilation fan for ventilating the room is used by supplying power from the AC line. However, in buildings easily built outdoors such as public telephone booths, warehouses, or storage rooms, ventilation is often inadequate because only slit-shaped ventilation openings are provided on the wall surface.

Therefore, a method of using a ventilation fan using an AC line is introduced, but it is difficult to adopt a configuration in which power is supplied to a building built at a position away from the AC line.

[0005]

[Problems to be solved by the device]

 From such a point of view, it is possible to drive a ventilation fan using a solar cell, but it is indispensable to install a solar cell in the building or attach a ventilation fan, which is structurally complicated and requires a simple structure. It was not suitable for telephone boxes and storage boxes that are used.

[0006]

[Means for Solving the Problems]

 The present invention is provided with a slit-shaped ventilation opening provided on a wall surface, a solar cell having a width and a thickness that can be inserted through the ventilation opening, a solar cell supported and driven by electric power generated by the solar cell. It consists of a ventilation fan that projects from the inside of the wall surface through a slit in the wall surface and fixes the ventilation fan to the wall surface through the slit so that ventilation is possible. After projecting the solar cell from the inside of the wall surface through the slit in the wall surface, the solar cell is rotated around the fulcrum to fix the ventilation fan to the wall surface so that ventilation is possible through the slit.

[0007]

[Action]

 According to the present invention, a slit-shaped ventilation opening is provided on the wall surface, and the solar cell can be easily attached by inserting the solar cell into the ventilation opening. The ventilation fan is powered by the power generated by the solar cell. Can be operated.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. 1 and 2 are an internal perspective perspective view and a perspective view of the main body of a ventilation fan with a solar cell according to the present invention with the ventilation fan main body fixed, for example, when it is attached to a ready-made public telephone box. Is shown. Reference numeral 1 is a ready-made box body that forms a space, and is assembled by inserting a glass plate into an aluminum frame. Reference numeral 2 denotes a ventilation port provided in a slit shape above the box body 1, and has a size of about 3 cm in length and 30 cm in width. Reference numeral 3 denotes a ventilation fan main body. An intake port 4 is provided on the upper surface of the main body 3, and a slit-shaped exhaust port 5 is provided on a side surface of the main body 3 which is in contact with the ventilation port 2. The air sucked from the intake port 4 is discharged to the exhaust port 5 by the rotation of the fan 6. Numeral 7 is a solar cell panel made of single crystal, polycrystal or amorphous silicon which generates power when irradiated with light, and is formed in a panel shape with a length of 25 cm, a width of 15 cm and a thickness of about 1 cm. The solar cell panel 7 is provided in parallel with the slit-shaped exhaust port 5 of the ventilation fan main body 3. Then, the fan 6 of the ventilation fan main body 3 is rotated by the electric power generated by the solar cell panel 7.

Next, a case where the ventilation fan main body 3 having the solar cell panel 7 protruding in this manner is installed in the box body 1 will be described. The solar cell panel 7 protruding from the ventilation fan main body 3 is projected outside the wall surface of the box body 1 to fix the ventilation fan main body 3 to the wall surface. At this time, the slit-shaped ventilation port 2 of the box body 1 and the exhaust port 5 of the ventilation fan main body 3 are aligned with each other, and the exhaust air from the exhaust port 5 is drawn out of the box body 1 through the slit-shaped ventilation port 2. It is necessary to fix the ventilation fan main body 3 to the wall surface of the box body 1.

Next, the operation will be described. During sunshine, the temperature inside the box 1 rises and the inside of the box 1 becomes uncomfortable. At the same time, sunlight is applied to the solar cell panel 7. This solar cell panel 7 generates electricity with high output. This electric power rotates the fan 6 built in the ventilation fan main body 3, takes in unpleasant air in the box body 1 from the intake port 4, is discharged to the exhaust port 5 through the fan 6, and the air in the box body 1 is slit. It is discharged to the outside of the box 1 through the ventilation hole 2. In this way, as long as the sunlight is continuously applied to the solar cell panel 7, the ventilation fan is driven to enable ventilation.

3, 4 and 5 show another embodiment of the ventilation fan with a solar cell according to the present invention. An internal perspective view of the main part of the ventilation fan with a solar cell in a state where the ventilation fan is fixed, It is a perspective view and sectional drawing at the time of installing a ventilation fan. The same parts as those shown in FIGS. 1 and 2 are designated by the same reference numerals. 8 is a solar battery panel composed of single crystal, polycrystal or amorphous silicon that generates power when irradiated with light. This solar cell panel 8 is inserted from inside the box 1 through a slit-shaped ventilation port 2. In the state where the solar cell panel 8 is projected to the outside of the box body 1, the solar cell panel 8 is exposed to sunlight by rotating it about the shaft fulcrum of the shaft 9 provided at one end of the solar cell panel 8 and providing it parallel to the wall surface. It can be irradiated. Magnets 10 are attached to the back surface where the solar cell panel 8 is not provided and to the side surface portion of the main body 3 that is in contact with the back surface portion and sandwiches the wall surface, and the ventilation fan is fixed.

In the ventilation fan thus installed, sunlight is applied to the solar cell panel 8 to generate electricity. The generated power causes the fan 6 of the ventilation fan main body 3 to rotate, and the air in the box body 1 is taken in through the intake port 4 and discharged through the fan 6 to the exhaust port 6.

The solar cell panels 7 and 8 may be installed according to the direction of sunlight.
