(First Embodiment)
FIG. 1 is a schematic front view for explaining the window panel 10 according to the first embodiment of the present disclosure. FIG. 2 is a schematic vertical sectional view taken along the line AA of the window panel 10 shown in FIG. The window panel 10 is arranged at the opening of the building.

In the present embodiment, the window panel 10 includes an outdoor panel 11 and an indoor panel 12 having translucency. The outdoor panel 11 and the indoor panel 12 are arranged parallel to each other. The outdoor panel 11 and the indoor panel 12 may be made of glass or may be made of resin (for example, made of polycarbonate or acrylic).

In the window panel 10 according to the present embodiment, a plurality of strip-shaped solar heat reflecting films 14 are formed on the indoor side surface 11a of the outdoor panel 11 at predetermined intervals B in the vertical direction V. Similarly, on the outdoor surface 12a of the indoor panel 12, a plurality of strip-shaped solar heat reflecting films 15 are formed at predetermined intervals B in the vertical direction V. The strip-shaped solar heat reflecting films 14 and 15 extend in the horizontal direction H. The width A of the solar heat reflecting films 14 and 15 is substantially the same as the interval B. The width A and the interval B may be several mm to several cm.

The solar heat reflecting films 14 and 15 have a high visible light transmittance and a function of reflecting solar heat, and may be formed of, for example, titanium, stainless steel, tin, chromium, or the like.

The outdoor panel 11 and the indoor panel 12 are arranged in parallel with each other so that the solar heat reflecting film 14 and the solar heat reflecting film 15 face each other. In FIG. 2, for the sake of explanation, the film thicknesses of the solar heat reflecting films 14 and 15 are displayed larger than they actually are. Since the film thicknesses of the solar heat reflecting films 14 and 15 are about 0.1 mm, there is almost no unevenness. Therefore, in reality, there is almost no gap between the indoor side surface 11a of the outdoor panel 11 and the outdoor side surface 12a of the indoor side panel, and the indoor side surface 11a of the outdoor panel 11 and the outdoor side surface 12a of the indoor side panel are substantially equivalent. Please note that it is in contact.

In the present embodiment, the outdoor panel 11 is movably supported in the vertical direction V with respect to the indoor panel 12. The indoor side panel 12 is fixed to a window frame (not shown). The support structure of the outdoor panel 11 is not particularly limited. For example, guide rails may be arranged at both ends of the outdoor panel 11 and the indoor panel 12 in the horizontal direction to movably support the outdoor panel 11 with respect to the indoor panel 12.

The window panel 10 according to the present embodiment further includes a panel moving mechanism 30. The panel moving mechanism 30 moves the outdoor panel 11 forward and backward with respect to the indoor panel 12 in the vertical direction V. In the embodiment shown in FIGS. 1 and 2, the panel moving mechanism 30 is configured to act on the lower end of the outdoor panel 11 and is displayed so as to be located below the outdoor panel 11. , The point of action and the position thereof are not particularly limited.

FIG. 2 shows a state in which the outdoor panel 11 is not moved with respect to the indoor panel 12. In this state, the solar heat reflecting films 14 and 15 are at substantially the same position in the vertical direction V (that is, the solar heat reflecting films 14 and 15 are exactly overlapped), and a gap 16 is provided between the solar heat reflecting films 14 and 15. exist.

FIG. 3 shows a state in which the outdoor panel 11 is moved by the panel moving mechanism 30. In FIG. 3, the outdoor panel 11 is moved vertically upward by a distance C with respect to the indoor panel 12. The distance C is substantially the same as the width A and the distance B. Therefore, when the outdoor panel 11 is moved, the solar heat reflecting film 14 and the solar heat reflecting film 15 are alternately positioned in the vertical direction V, and there is no gap between the solar heat reflecting films.

4 (a) and 4 (b) are diagrams for explaining the operation of the window panel 10 according to the first embodiment. FIG. 4A shows a usage state in winter, and FIG. 4B shows a usage state in summer. 4 (a) and 4 (b) show the solar heat from the sun.

And are in substantially the same position in the vertical direction V, and there is a gap 16 between the solar heat reflecting films 14 and 15. Therefore, a part of the solar heat can be taken into the inside of the window panel 10 (that is, the room) through the gap 16 (incident heat). As described above, according to the window panel 10 according to the present embodiment, the necessary solar heat can be taken into the room in the winter, and the solar heat acquisition rate can be relatively high.

On the other hand, as shown in FIG. 4B, in the summer when the solar altitude is relatively high, the outdoor panel 11 has the width A (interval) of the solar heat reflecting films 14 and 15 in the vertical direction V with respect to the indoor panel 12. B) It is in a state of being moved by a minute, that is, a state in which the solar heat reflecting film 14 and the solar heat reflecting film 15 are alternately positioned in the protruding direction P, and there is no gap between the solar heat reflecting films 14 and 15. Therefore, the solar heat is reflected by the solar heat reflecting films 14 and 15 and released to the outdoor side (reflected heat). As described above, according to the window panel 10 according to the present embodiment, unnecessary solar heat can be blocked and the solar heat acquisition rate can be relatively low in the summer.

As described above, according to the window panel 10 according to the present embodiment, the outdoor panel 11 is moved by the width of the solar heat reflecting films 14 and 15, that is, only a few mm to a few cm with respect to the indoor panel 12. By doing so, it is possible to switch between blocking the solar heat and taking in the solar heat. Since unnecessary solar heat can be blocked in the summer and necessary solar heat can be efficiently taken in in the winter, solar energy can be used efficiently. Although the use of the window panel 10 in the summer and winter has been described here for the purpose of making the explanation easy to understand, the window panel 10 according to the present embodiment is exposed to solar heat when the user feels hot regardless of the season. Please note that it is possible to take in solar heat if it is blocked and feels cold. For example, the panel moving mechanism 30 may be automatically controlled according to the room temperature.
