Description

[Detailed description of the invention] The present invention relates to a skylight having a ventilation structure.

Skylights are effectively used in rooms with few windows to let in outdoor light during the day. Conventionally,
Such skylights generally cover windows installed in the roof with lighting materials such as glass tiles or transparent plastic, and cover windows installed in the ceiling with light control materials such as diffusers.
The outer peripheries of the roof window and ceiling window are connected by side panels to form an interior space, and the light taken in from the roof window through the lighting member is irradiated into the room through the light control member of the ceiling window. .

By the way, in general, as light comes in from a skylight,
The indoor temperature tends to rise, which is desirable in the winter, but undesirable in the summer because it increases the heat. In addition, the temperature rise due to daylighting is significant in the interior space surrounded by the side panels of skylights, and the heat accumulated in this interior space is not effectively used in the winter because it is difficult to transmit indoors, and in the summer it is not used outdoors. Since it is not released into the atmosphere, the temperature inside the room gradually increases. Skylights are also known in which curtain-type or sliding shutters are attached to ceiling windows to cut out incident light in the summer, but once the shutters are closed, they no longer function as skylights, and when the shutters are closed, However, the heat accumulated in the interior space of the skylight cannot be reduced.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a skylight that moves heat accumulated in the interior space of the skylight or indoors to improve the indoor temperature environment.

According to the present invention, an internal space is formed by connecting the lighting member that covers the window provided on the roof, the light control member that covers the window provided on the ceiling, and the outer periphery of the window on the roof and the window on the ceiling. A ventilation structure is provided that includes a side plate and communicates the indoor space, the interior space, and the outdoors.

Therefore, with the light coming through the skylight, the heat accumulated in the interior space of the skylight and inside the room can be moved together with the air flow through the ventilation structure, thereby improving the indoor temperature environment.

In the present invention, the ventilation structure includes a first duct extending from the indoor space to the interior space of the skylight, and a second duct extending from the interior space of the skylight to the outdoors. According to this, when the indoor temperature rises due to daylighting, air flows from the room into the interior space through the first duct, and then flows out from the interior space to the outdoors through the second duct. , heat from indoors and internal spaces is released to the outdoors.

In particular, according to the present invention, the ventilation structure includes a first duct that extends from the indoor space to the inner space of the skylight, a second duct that extends from the inner space of the skylight to the outdoors, and a second duct that branches from the second duct and extends indoors. 3, a switching valve provided at a branch portion of the second duct and a third duct, and a fan provided at an inlet portion of the second duct. According to this, in the summer, the switching valve is switched so that the second duct communicates with the outdoors, creating a flow of air from indoors to the outdoors through the interior space of the skylight, and in the winter, the switching valve is switched so that the second duct communicates with the outdoors. The second duct can be switched to open into the third duct to create a flow of air from the interior through the interior space of the skylight and back into the interior. Furthermore, a fan is attached to the inlet of the second duct, and this fan is rotated to enter the interior space from the room through the first duct, and from the interior space to the second duct and the ventilator. This creates an airflow that exits outdoors through the roof and allows the accumulated heat to be dissipated to the outdoors. Therefore, in the summer, the heat in the room or internal space can be released to the outside, and in the winter, the heat in the internal space can be transferred indoors to increase the indoor temperature.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the invention. A window 1 having a rectangular opening, for example, is provided on the preferably southern slope of the roof L.
A frame 2 made of synthetic resin or the like is fitted into the window 1. A transparent plastic plate 3 is attached to the upper surface of the frame 2 to seal the window 1. The upper surface of the transparent plastic plate 3 is covered with a glass tile 4, which reinforces the transparent plastic plate 3 and prevents sand and dust from accumulating on the transparent plastic plate 3. In addition,
Heat-resistant glass may be used instead of the transparent plastic plate 3. On the other hand, a window 5 is provided in the ceiling C, and the window 5 has an opening corresponding to the lower part of the window 1. A diffusion plate 6 made of polycarbonate resin or the like having an uneven surface is attached to the lower surface of the window 5. Window 5 is sealed. A heat insulating shade 7 is provided above the diffusion plate 6.

A side plate 8 is attached between the window 1 on the roof L and the window 5 on the ceiling C so as to connect their outer peripheries, thereby forming an interior space 9.

The above configuration is almost the same as a conventional skylight.

In this embodiment, one end is the ceiling C.
The other end is opened at the bottom of the side plate 8, and the other end is opened at the lower part of the side plate 8.
A first duct 10 is provided that communicates the interior space 9 with the interior space 9 . Further, a second duct 11 is provided that connects the interior space 9 and the outdoors A, with one end opening at the top of the side plate 8 and the other end opening at the roof L. The first duct 10 and the second duct 11 are made of a flexible material such as synthetic resin to facilitate piping work. moreover,
In the opening in the roof L of the second duct 11,
A ventilation roof 12 is attached to prevent rainwater from entering.

In the above configuration, sunlight is transmitted through window 1 of roof L.
The light enters the interior space 9 through the glass tile 4 and the transparent plastic plate 3. The incident light is further radiated into the room from the window 5 in the ceiling C through the heat insulating shade 7 and the diffuser plate 6. And with the lighting,
The temperature of the internal space 9 and the room H increases. Since the heated air becomes lighter and flows upward, it enters the interior space 9 from the indoor space H through the first duct 10, and then passes from the interior space 9 through the second duct 11 and the ventilation roof 12 to the outside. An air flow is created that exits at A. Due to the air flow, the heat accumulated in the room H and the interior space 9 is released to the outdoors A, and for example, in the summer, it is possible to suppress the rise in the room temperature due to daylighting.

In this embodiment, a third duct 13 is provided which branches off from the second duct 11, opens into the ceiling C, and communicates the second duct 11 with the room H. Also, the second duct 11 and the third duct 13
A switching valve 14 for switching the air flow path to the outdoor A side and the indoor H side is attached to the branching portion. This switching valve 14 can be operated from the room H by an interlocking mechanism (not shown).
Furthermore, a fan 15 is attached to the entrance of the second duct 11, and the fan 15 is driven by the electromotive force of a solar panel 16 provided on the roof L.

Therefore, in this embodiment, for example, in the summer, the switching valve 14 is switched so that the air flow path is connected to the outdoor side A, and the fan 15 is rotated to allow the air to flow from the room H through the first duct 10 to the inside. Creating an air flow that enters the space 9 and further flows out from the interior space 9 to the outdoors A through the second duct 11 and the ventilation roof 12, and releases the heat accumulated by this air flow to the outdoors A. Can be done. Also,
In this case, a ventilation effect that purifies the air in the room H can also be expected. Next, for example, in winter, the switching valve 14 is switched so that the air flow path leads to the indoor H side, the fan 15 is rotated, and the first
An air flow is generated which enters the interior space 9 through the duct 10 of the interior space 9 and returns to the room H from the interior space 9 through the second duct 11 and the third duct 13. The accumulated heat can be transferred to the indoor room H to increase the indoor temperature.

Another embodiment of the invention is shown in FIGS. 2 and 3. As shown in FIG. 2, the inlet portion of the second duct 11 is filled with a heat storage member 17 such as a ceramic ball. As shown in FIG. 3, the window 1 of the roof L is provided with a daylighting zone 18 and a heat-gathering zone 19. In this case, as the heat collection zone 19, a heat-absorbing plate material or the like can be used.

Therefore, in this embodiment, the daylighting zone 18
In addition to the temperature-raising effect associated with daylighting from
With the addition of an active temperature raising action from 9, the inside of the internal space 9 becomes even hotter. This heat is transferred by an air flow from the room H through the interior space 9 to the outdoors A or the room H due to the rotation of the fan 15, and at this time, the air flow contacts the heat storage member 17 and heat storage occurs. . For example, when it is desired to raise the indoor temperature at night, the switching valve 14 is switched to the indoor H side to generate an air flow from the indoor H through the internal space 9 and return to the indoor H, thereby storing heat during the day. The heat accumulated in the member 17 is transferred to the indoor H.
can be heated. Note that a heat exchanger or the like may be arranged in place of the heat storage member 17, and the heat within the internal space 9 may be used for various purposes.

In each of the embodiments described above, the heat insulating shade 7 and the diffuser plate 6 are used as light control members, but the diffuser plate 6 may be replaced by electrochromic or photochromic glass. In that case,
The amount of daylight can be automatically adjusted depending on the strength of the sun's rays.

As explained above, according to the present invention, a ventilation structure is provided that communicates the interior space of the skylight with the outdoors, so that the heat accumulated in the interior space of the skylight and the interior of the room due to sunlight is removed by ventilation. Due to its structure, it can be moved along with the air flow, thereby improving the indoor temperature environment.
