Description

[Detailed Description of the Invention] This invention relates to a bay window that can simultaneously achieve indoor heating and ventilation using solar thermal energy.

Traditionally, bay windows have been provided with skylights, which let in more light and heat, brightening the room and increasing the heating effect to some extent. In addition to bay windows, there are also so-called solar houses in which a heat collecting plate is attached to the roof of the building and the heat energy captured by this is introduced indoors.

However, we believe that no technology has yet been proposed that utilizes solar thermal energy for heating and promoting ventilation while effectively air-conditioning a room in winter and summer.

This invention was proposed from the above-mentioned viewpoint, and will be explained below with reference to drawings showing an embodiment of this invention. Fig. 1 is a perspective view of a bay window seen from the indoor side, and is indicated by an arrow. The object indicates the state of air circulation. Figure 2 shows the state viewed from outside the room. That is, 1 is a bay window main body provided extending from the building to the outdoor side, and includes a bay window section 1a, a roof section 1b, and a base plate section 1c.
A window glass 2 is attached to the front central part of the bay window part 1a of the bay window main body 1, and the roof part 1b is formed into a skylight 3 that can let in sunlight. 4 is the heat collecting part,
As shown in FIGS. 2 to 4, the window glass 2
It is arranged at the front lower part of the lower overhanging window part 1a. The heat collecting part 4 may be made of a metal plate with excellent thermal conductivity such as aluminum, copper or galvanized steel, or may be coated with black paint on its surface, or may be made of metal oxides (FeOx, CuO, etc.).
CrOx, etc.) or metal sulfides (NiS, ZnS, etc.) and coated with Ni, Fe, Ca, Al, etc.), or a transparent plate such as a glass plate polycarbonate is placed above it. It is preferable that the
Reference numeral 5 denotes a cavity provided so as to be in contact with the entire inner surface of the heat collecting section 4, and on the lower side of the cavity 5, there are a plurality of (for example, three) cavities whose one end 7 opens near the floor surface on the indoor side. The other end of the lower ventilation duct 6 is connected for communication, and the upper side of the cavity 5 has an open end 12 whose tip end opens near the ceiling on the indoor side, and an open end 12 that passes through the roof 1b and extends to the outdoor side. For example, the base end portions of two upper ventilation ducts 8 that are branched to the open end portion 13 are connected in communication. Each lower side ventilation duct 6
is horizontally piped along the base plate 1c of the window frame body 1, and a damper 11 (see FIG. 3b) which can be opened and closed is attached to the indoor opening end 7 of the pipe. Each upper ventilation duct 6 extends almost horizontally from the cavity 5 along the side surface of the bay window 1a toward the built-in part of the bay window main body 1, and from there extends upward along the built-in part to its tip. The opening end 12 of one branch duct 9 opens to the indoor side, and the open end 13 of the other branch duct 10 opens to the outdoor side. ,10
As shown in FIGS. 3a and 3b, dampers 14 and 15, which can be opened and closed, are attached to the open ends 12 and 13 of the dampers 12 and 13, respectively.

A louver 16 that can be opened and closed by a well-known method is attached to the outdoor side of the skylight 3, and an insulating door 17 whose one end is pivoted to the overhang window frame by a well-known method is attached to the indoor side of the skylight 3. It is provided so that it can be opened and closed freely.

Further, on the indoor side of the window glass 2, a heat collecting screen 18 is provided, which has a well-known screen or curtain structure that can be drawn out and stored vertically or horizontally, and is coated with a heat collecting material. The structural material of the heating section 4 is appropriately selected. Furthermore, a heat shielding screen 19 having poor thermal conductivity and reflective properties, for example, treated with silver foil, is similarly attached to the indoor side of the heat collecting screen 18 in parallel with the heat collecting screen 18. Furthermore, the heat collecting part 4 and the window glass 2 which are above the heat collecting part 4
A shelf board 20 is attached to the indoor side from the boundary between the heat collecting part 4, the shelf board 20, and the base plate part 1c.
A required storage space 21 is formed in a portion surrounded by. A heat insulating material 22 is attached to the storage space 21 along the inner circumferential wall of the cavity 5 in order to prevent heat conduction from the heat collecting section 13 .

This device has the above-mentioned configuration, and its usage is as shown in Figure 3a, mainly during the daytime in winter, when the louver 16 and the heat insulating door 17 are opened and the sun's rays are directed through the skylight 3 as indicated by the arrow. The solar thermal energy is introduced into the room to collect sunlight and heat, and the heat rays of the sun's rays are introduced into the room by pulling out the heat collecting screen 18 on the window glass 2 as shown by the arrows, and the solar heat energy is further collected into the heat collecting part 4. The damper 15 of the branch duct 10 that opens to the outside of the room at the tip end of the upper ventilation duct 8 is closed, and the damper 15 of the branch duct 10 that opens to the outside of the room is opened to the outside of the room at the tip of the upper ventilation duct 8. The damper 14 of the branch duct 9 and the damper 11 of the open end 7 of the lower ventilation duct 6 are opened. Therefore, the sunlight is efficiently introduced into the room as described above, and the indoor air enters the cavity 5 from the lower ventilation duct 6 and flows from there through the upper ventilation duct 8 and its branch duct 9. As the heat is circulated as shown, the temperature in the cavity 5 in contact with the heat collecting part 4 is increased sequentially, and the synergistic effect of these heats the room.

At night in winter, the insulation door 17 is closed and the lower ventilation duct 6 is closed, as shown in Figure 3b.
By closing the damper 11 of the upper ventilation duct 8 and the damper 14 of the branch duct 9 of the upper ventilation duct 8, indoor air warmed during the daytime is prevented from leaking to the outside.

Furthermore, in the summer, as shown in FIG. 4, the louver 16 is closed to prevent sunlight from entering the room as shown by the arrow, and a heat collecting screen 18 is housed in the window glass 2 to block it. thermal screen 1
9 to prevent sunlight entering the room through the window glass as shown by the arrow.
In addition, by opening the damper 11 of the lower ventilation duct 6 and the dampers 14 and 15 of the branch ducts 9 and 10 of the upper ventilation duct 8, high temperature outside air is introduced into the room as much as possible. At the same time, indoor air flows from the lower ventilation duct 6 to the cavity 5 to the upper ventilation duct 8 as shown by the arrow.
and is discharged outdoors through the branch duct 10, and from the branch duct 9 to the branch duct 10. At this time, the air in the cavity 5 is heated by the thermal energy received by the heat collecting part 4, and an upward airflow phenomenon occurs from the lower ventilation duct 6 to the upper ventilation duct 8. This phenomenon forces the air inside the duct to be semi-forcibly discharged outside, improving the ventilation effect.

As described above, according to this invention, a bay window main body is formed that extends to the outside of the room and consists of a bay window section, a roof section, and a base plate section, and a window glass is attached to the center of the bay window section. In a bay window, the roof is formed into a skylight that allows sunlight to enter, and a louver that can be opened and closed is attached to the skylight. By opening and closing the louver, the entry of sunlight into the room can be adjusted, and the interior can be brightened in winter and summer. The temperature can be maintained in a good condition. In particular, a heat collecting part is provided at the bottom of the overhanging window below the window glass, and a hollow part is provided in contact with the entire inner surface of the heat collecting part, and one end of the hollow part touches the indoor floor. While connecting the other end of the lower ventilation duct that opens nearby,
On the upper side of the cavity, the base end of the upper ventilation duct, which is branched into a duct end whose distal end opens near the ceiling on the indoor side and a duct end whose tip opens toward the outdoor side from the roof, is connected in communication. As a result, the air inside the cavity is heated by the thermal energy received by the heat collecting section, causing an upward airflow phenomenon from the lower ventilation duct to the upper ventilation duct. When energized, it exhibits a remarkable effect of promoting ventilation of indoor air extremely well.
