Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double glazing of a building, and more particularly, to use solar energy to create an air curtain, which effectively conducts heat to and from the building through the window. The present invention relates to a double-glazed window that can be cut off and the air conditioning cost can be significantly reduced.

[0002]

2. Description of the Related Art When an air flow is created along a window of a building to form a so-called air curtain, heat conduction to and from the inside and outside of the building through the window is effectively blocked, and the cooling efficiency and heating efficiency inside the building are significantly improved. It is known to be increased. However, if the blower is driven by a commercial power source when making this air curtain, electric power is consumed for driving the blower, which is a negative factor in reducing the air conditioning cost.

On the other hand, the solar cell converts light energy into electric energy, and from the viewpoint of solving the global environmental problems such as the global warming problem, the spread of the solar cell must be actively promoted. It is one of the challenges. Among the solar cells, amorphous solar cells have recently attracted attention because they are lightweight, suitable for mass production, and low in cost, although the energy conversion efficiency is slightly inferior to that of crystalline solar cells. In the case of using such a solar cell to obtain electric energy in a building, conventionally, a pedestal is installed on a rooftop and the solar cell is arranged on this pedestal.

[0004]

Therefore, in order to obtain electric energy using a solar cell, a stand for the solar cell is required, and it is necessary to secure a space for installing the stand, which results in cost reduction. There was a problem in terms of points and space. By the way, the window is often provided with a blind composed of a large number of blades in order to adjust the amount of solar radiation into the building. And, although this blind is originally arranged at a place where it receives enough sunlight energy, in the past, it does not utilize the received sunlight energy at all,
It just blocks the sun. The present invention was devised by paying attention to these amorphous solar cells and blinds, and an object of the present invention is to create an air curtain using solar energy in a window of a building, which allows the window to pass through the window. It is to provide a double glazing that can effectively cut the heat conduction to and from the building and significantly reduce the air conditioning cost.

[0005]

In order to achieve the above-mentioned object, the present invention is directed to a double-paned inner and outer window glass which is arranged in an opening of a building and defines a space in the opening, and a large number of vanes. And a blind disposed in the space, an air intake opening inside the building and communicating with a space part near one of the two facing sides of the opening, and outside the building. An air outlet that is opened and communicates with a space portion near the other of the two opposite sides of the opening; a blower that sucks air from the air intake and discharges air from the air outlet; It is characterized in that the vane plates are provided with amorphous solar cell panels respectively attached to the surfaces that receive sunlight, and conduction means for supplying the electric power generated by the amorphous solar cell panels to the drive motor of the blower.

The blind 11 has a plurality of blades 110.
The blind 11 includes an elevating mechanism that is connected to each vane plate 1101 to elevate the vane plate 1101 and an adjusting mechanism that is connected to each vane plate 1101 and adjusts the angle of the vane plate 1101. Top 50 of double glazing 3
It is extended from 1 to the lower side 505, thereby shielding sunlight and changing the angle of the blade 1101 to adjust the amount of daylight to the inside of the building, and when not in use, it is in a state of being superimposed on the upper side 501 side. As a result, a conventionally known structure for opening the double window 3 is used. As shown in the cross-sectional view of FIG. 2, each of the vane plates 1101 faces the sun 1 with the double window 3 shielded.
101A and a back surface 1101B facing the inside of the building,

It is 5 mm and-also functions as an electrode. An amorphous silicon layer 25 is formed on the stainless steel substrate 23, and the amorphous silicon layer 25 is a P layer, an I layer, and an N layer necessary for forming an amorphous solar cell.
It is formed of a known multilayer structure including layers. A transparent electrode 27 is formed on the amorphous silicon layer 25,
The transparent electrode 27 functions as a + electrode.

A fluorine resin is coated on the bottom of the stainless steel substrate 23 and on the transparent electrode 27 to form protective layers 29, 3.

The transparent electrode 27 and the protective layer 31 side is the light receiving surface (front surface) 21A of the amorphous solar cell panel 21, and the stainless steel substrate 23 and the protective layer 29 side is the back surface 21B of the amorphous solar cell panel 21. On the back surface 21B of the amorphous solar cell panel 21, a base layer 33 made of synthetic resin for firmly attaching the amorphous solar cell panel 21 to the vane plate 1101 is formed. The amorphous solar cell panel 21 has a thickness of 3 mm or less excluding the underlayer 33 and has some flexibility, and the underlayer 33 also has flexibility.

It is incorporated in the space 9 above. The air intake 13 is opened in the lower part of the inner glass plate 7, the air outlet 15 is opened in the upper part of the outer glass plate 7, and the air inside the building is sucked from the air intake 13 by the drive of the blower 17. The air is blown upward from the slit plates 37 arranged in front of and behind the blind 11, and is discharged from the air discharge port 15 to the outside of the building. This creates an air flow in the space 9 from the lower side 505 to the upper side 501, so that a so-called air curtain is formed before and after the blind 11. The drive motor of the blower 17 is connected to the lead wire 35, and the blower 17 is driven by the electric power generated by the amorphous solar cell panel 21.
