Description

[Detailed description of the invention] The present invention relates to a solar heat utilization device, and more specifically, a blind type solar heat collector is installed in a space inside a double-glazed window facing the outside air of a building, and the upper and lower parts of the space are connected indoors and outdoors. This invention relates to improvements to solar heat collection windows that can be opened and closed from both sides.

The conventionally known structure consists of two glass plates facing each other with a space between them, a solar heat collector placed in the space, and air intake and exhaust ports that can be opened and closed above and below the space leading to the inside of the room. will be established. In use, if both intake and exhaust ports are left open during winter sunshine, the low-temperature air in the room flows into the space from the lower intake and exhaust ports, is heated by the solar heat collector, and rises inside the space. Hot air enters the room through the upper air intake and exhaust vents and warms the low-temperature air in the room. Also, at night, both intake and exhaust ports are closed to prevent air convection between the room and the space, and to prevent low-temperature air in the space cooled by outside air from flowing into the room.

However, the intake/exhaust port of the conventional structure described above has a drawback that the structure is complicated and the construction cost is high. Furthermore, in the summer, both intake and exhaust ports are closed in the same way as at night in the winter, but the temperature in the space rises, increasing the cooling load in the room.

The object of the present invention is to provide an effective opening/closing window for solar heat collection that has a simple structure, eliminates the above-mentioned drawbacks, and is useful for energy saving.

The present invention will be described below with reference to Examples.

In Figures 1 to 3, the window frames are upper frame 1,
It is composed of a lower frame 2 and a vertical frame 3. Inside the above window frame, a shoji A consisting of a shoji main body 4 and a small shoji 12 is attached to the center part of the upper frame 1 and the lower frame 2, respectively.
5 and 25 so as to rotate on a vertical axis. Tight materials 5, 5, . . . are provided on the four peripheral edges of the shoji A at the portions that slide on the inside of the window frame, respectively, to seal the space between the shoji and the window frame. A solar heat ray transmitting plate 6 is hermetically fitted on the outdoor side of the shoji main body 4 via a tight material 7 and a sealing material 8, and a Venetian blind type solar heat collector 9 is disposed inside the shoji body 4, that is, on the indoor side. The blind type solar heat collector 9 has a plurality of heat collecting slats 10 whose upper surfaces are reflective surfaces and whose lower surfaces are heat collecting surfaces.
When used during the heating season, solar heat rays are reflected on the top surface of the slats, and by adjusting the angle of the slats, they are absorbed by the bottom surface of the slats. The air inside the room is warmed and sent into the room to assist in heating. In addition, when used in the summer, there are various blind type solar collectors that reflect the solar heat rays reflected from the heat ray reflecting surface on the top surface of the slats to the outdoors to prevent the slats from rising in temperature. A blind type solar heat collector whose surface is formed to reflect heat rays, and whose slat surface is reversed during winter and summer. Alternatively, first slats (not shown) having a heat ray absorbing surface on the upper surface and second slats (not shown) having a heat ray reflecting surface on the upper surface are arranged alternately, and in winter, each second slat is placed above the first slats (not shown). In the summer, each second slat is pulled down to the top surface of each first slat adjacent to it, and the top surface of all the slats is used as a heat ray absorbing surface or a heat ray reflecting surface. It is also possible to use blind type solar heat collectors.

In the case of this embodiment, the indoor side of the solar heat collector 9 is open, and a small shoji 12 (described below) is placed on this side.
Install.

The small shoji 12 has a transparent plate 13 or an opaque panel attached to the upper frame 14 through a tight material 7 and a sealing material 8.
It is fitted into a transparent board stile composed of a lower stile 15 and a vertical stile 16, and an appropriate gap G is provided between the upper stile 14, lower stile 15 and the shoji body 4 over the width of the upper and lower stile. provided. 17 is a hinge attached to the upper stile 14, 1
Reference numeral 8 denotes a fixing metal fitting attached to the lower stile 15, and both allow the small shoji 12 to be opened and closed in an undulating manner while maintaining the gap G around the hinge. 19, 19 are gap closing members formed on the upper and lower end surfaces of the small shoji 12, respectively, over the width of the upper and lower frames, and long guide holes 20, 20 along the indoor and outdoor directions are provided on the substrate, and the ventilation holes 2
Bolts 21 and 21 loosely fitted in holes 0 and 20 are fixed to the upper stile 14 and the lower stile 15, respectively. Also, gap closing member 1
9 and 19 have tight materials 22 and 22 attached to the outdoor side, and handle parts 23 and 23 by bending the ends to the indoor side.
will be established.

Upper and lower gap closing members 19, 19 during winter sunshine
When the gap G is opened by pulling it to the position shown by the dotted line (that is, toward the room), the low-temperature air in the room flows as shown by the arrow A ₁ −A ₂ −A ₃
- A ₄ enters the space 11 in the order of 4, is heated by the solar collector, and returns indoors again. At night in winter, when the upper and lower gap closing materials 19, 19 are pushed toward the outdoor side, the tight materials 22, 22 come into contact with the indoor side surfaces of the shoji main body 4 to keep the space 11 sealed. Small shoji 12 vertical stile 16,
16 and the shoji body 4, gap closing members 24, 24 similar to the gap closing member 19 are fixed to the vertical stile, and tight materials 22, 22 provided on the outdoor side of the closing members are brought into contact with the shoji body 4. Close the gaps in the vertical direction. Air circulation therefore takes place only in the vertical direction.
Note that the gap closing member 24 may be integrated with the vertical stile 16.

According to the present invention, in the summer when the solar heat collector 9 is not used, the shoji main body 4 is vertically rotated 180 degrees via the shafts 25, 25 with the upper and lower gaps G open, and the small shoji 12 is moved to the outdoor side. turn to The slats 10 of the heat collecting room 9 are put into use in the summer, and the sunlight that passes through the panel 13 and enters is reflected to the outside of the room. In this case, the air in the space 11,G is slightly warmed,
Outside air enters through the gap G at the bottom, removes the heat, rises in the space, and is discharged outdoors through the vent 20 at the top. Also, if the gap G is closed at night, it becomes a normal double glass shoji.

This invention has a simple structure with a gap that can be opened and closed on the indoor side. When both gaps are left open during winter sunshine, low-temperature indoor air flows into the space from the lower gap and is absorbed by the solar heat collector. The heated air that rises in the space enters the room through the upper gap and can warm the low-temperature air in the room. In addition, during the summer sunshine, by rotating the small shoji with the upper and lower gaps open to face the outdoor side, heat from the outdoor side can be blocked and indoor cooling can be used effectively.
Further, at night in winter, both gaps are closed to prevent air convection between the room and the space, thereby preventing low-temperature air in the space cooled by outside air from flowing into the room. Furthermore, since the gap closing member for the air intake and air extraction gaps is a sliding type with a simple structure, it has many effects such as fewer failures. In addition, according to the embodiment, since the shoji main body and the small shoji attached to the shoji main body are movable, cleaning the outer surface of the solar heat ray transmitting plate and the area around the blind type solar heat collector is easy, and the access to the heat collector is improved. Good quality, easy inspection and adjustment. Furthermore, by sealing the space between the small shoji and the shoji main body with a heat insulating tight material, a double glass shoji with good insulation surrounding the heat collector can be obtained.
