Abstract

PURPOSE:To improve a heat insulating effect by a method wherein a sponge- form sheet formed of a material being a metal having a number of fine holes or a synthetic resin is fitted in a window frame and an amount of solar heat rays passing through is limited. CONSTITUTION:Plastic films 4 are laminated on both surfaces of a sponge-form thin layer formed of a metal or a synthetic resin having fine holes 3 with a size of 10 micron or less extending through in a direction between the obverse and the reverse to form a sponge-form sheet 1. The sheet l is directly attached to a window frame 2 or in juxtaposition with a surface glass or attached in a state that a vacuum layer is formed between a glass sheet and the sheet. Only the heat lays of solar light are cut out by the sponge-form thin layer, propagation of heat to the interior of a room is prevented from occurring, and a cooling load during a summer season is relieved. This structure improves the heat insulating effect of a window.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window structure having a heat ray protection function used on a roof or a wall surface of a building.

[0002]

2. Description of the Related Art Generally, in a daytime building in summer,
Is it is extremely large to receive the infrared effect of radiant heat caused by sunlight, radiant heat per hour ² per area of the building 1m 500
It is said to be kcal, and even in the case of wall glass, it is said that it reaches 300 kcal / m ² per 1 m ² of glass surface in case of the summer sunshine.

Therefore, when the entire ceiling of the building is made of glass, the indoor temperature rises abnormally due to the incidence of radiant heat (infrared radiation) on the inside of the building, and in order to maintain a comfortable indoor atmosphere, Although cooling was indispensable, the cooling load was inevitably large, and the equipment cost and operating cost were enormous.

By the way, 60% or more of the cooling load is the load from the glass surface, and most of the load is due to the radiant heat of the infrared rays of the sunlight, and the transfer between the outside air and the indoor air on the glass surface. The heat load is negligible.

That is, as long as the radiant heat (infrared rays) of the ceiling surface and the wall surface is blocked, the rise in the indoor temperature can be suppressed to a low level, and the indoor atmosphere can be maintained to some extent comfortable without using cooling. This is possible and the cooling load can be reduced.

Therefore, in the prior art, in order to block the radiant heat (infrared ray) of sunlight from entering the indoor space, a curtain or a blind for light shielding is installed on the ceiling surface or wall surface, or the material of the glass itself is protected against heat rays or heat rays. I changed it to one that has a reflection function, or I applied a film on the glass surface, but there was a problem in appearance and operation,
Moreover, not only is the effect of blocking radiant heat (infrared ray) not perfect, but it also has the drawback that the interior of the room becomes dark because it blocks visible light.

[0007]

The problem to be solved is that the conventional structure for blocking the radiant heat (infrared ray) of sunlight does not provide a complete radiant heat (infrared ray) blocking effect, and is also visible. This is to block even the light rays, and it is intended to obtain a structure in which the radiant heat (infrared rays) of the sunlight is blocked as much as possible and a ray other than infrared rays is allowed to pass through.

[0008]

According to the present invention, a sponge-like thin layer made of a metal or synthetic resin having a large number of fine holes penetrating in the front and back direction is fitted into a frame body as appropriate.

It is practical to attach thin pieces such as plastic films to the front and back surfaces of the spongy thin layer.

A surface glass may be provided on the outside of the spongy thin layer.

A spongy thin layer is preferably arranged in contact with the inside of the surface glass.

It is also conceivable that the inner surface glass is arranged inside the sponge-like thin layer with a space, and a space is formed between the inner surface glass and the surface glass.

The space is preferably sealed.

A vacuum pump may be communicated with the sealed space.

It is preferable that the spongy thin layer micropores have a size of 10 microns or less.

[0016]

The thin spongy layer is composed of a spongy metal having a three-dimensional mesh shape or a spongy resin and has a large number of fine holes penetrating in the front and back directions. Is there.

The amount of infrared rays of sunlight applied to the spongy thin layer is limited by a large number of fine holes penetrating the spongy thin layer in the front and back directions.

By attaching thin pieces such as a plastic film to the front and back surfaces of the sponge-like thin layer, it is possible to prevent dust from clogging the fine holes.

By arranging the surface glass on the outside of the spongy thin layer, it can be used as a window glass, and the infrared rays of the sunlight applied to this surface glass penetrate in the front and back directions of the spongy thin layer. Since the passing amount is limited by the large number of small holes, the temperature of the surface glass rises, but since the surface glass is in contact with the outside air, heat is sequentially radiated to the outside.

When the sponge-like thin layer is disposed in contact with the inside of the surface glass, the temperature of the surface glass can be efficiently raised, and heat radiation to the outside can be smoothly performed.

Further, by arranging an inner surface glass inside the sponge-like thin layer with a space therebetween, and forming a space between the inner surface glass and the surface glass, radiant heat passing through the spongy-like thin layer is propagated indoors. Is blocked by the space and the inner glass.

By sealing the space, it is possible to prevent the radiant heat from being dispersed due to the circulation of air and prevent the heat from propagating indoors.

By connecting a vacuum pump to the closed space and evacuating the closed space by the operation of the vacuum pump to bring it into a vacuum state, air convection can be eliminated and the surface glass can be transferred to the inner glass. The amount of heat can be extremely reduced, and the propagation of radiant heat from the outdoors can be almost blocked.

At night in winter, the indoor temperature is high and the outdoor temperature is low. The heat on the indoor side flows from the inner glass to the surface glass, but the closed space portion By exhausting the air into a vacuum state, convection of air is removed, and heat transfer from the indoor side to the outdoor side can be prevented.

Since the sponge-like thin layer basically has a function of blocking the passage of radiant heat (infrared rays), it is also possible to block a small amount of radiant heat from indoors.

When the micropores of the spongy thin layer are 10 μm or less, the passage of infrared rays and short heat rays having a wavelength of infrared rays or less is blocked, and the propagation of radiant heat to the inside is greatly reduced. 70 to 80% of radiant heat is blocked.

At this time, the weight of the sponge-like thin layer can be about 2% of the total weight of the metal or synthetic resin when compared with the original weight of the metal or synthetic resin. 80-90% of the light is allowed to pass,
The brightness of the room can be maintained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to the drawings, in which 1 is a spongy thin layer fitted in a frame 2.
The spongy thin layer 1 is made of metal or synthetic resin and has a three-dimensional mesh-like shape with a thickness of about 3 mm. And a thin piece 4 such as a plastic film is attached to the front and back surfaces.

Reference numeral 5 denotes a surface glass having a thickness of about 3 to 5 mm fitted in the frame body 2, and a spongy thin layer 1 is bonded and disposed on the entire inner surface thereof.

Reference numeral 6 denotes an inner surface glass which is placed inside the spongy thin layer 1 with an appropriate distance and is fitted into the frame body 2. The inner surface glass 6 has the same thickness as that of the surface glass 5, and both of the glass materials. A space portion 7 is provided between 5 and 6.

The space 7 is hermetically sealed by both the glasses 5 and 6 and the surrounding frame 2, and a communication pipe 9 to a vacuum pump 8 provided outside the frame is connected to the space 7 to form a vacuum. By operating the pump 8, the space 7 is brought into a vacuum state and the state is maintained.

In the embodiments of the drawings, a schematic explanatory view of the present invention is shown, but it is needless to say that accuracy is actually required in the frame body, glass, hermetically sealed structure and the like.

[0033]

Since the present invention is configured as described above, it is possible to remarkably reduce the incidence of radiant heat (infrared rays) of sunlight into the room, reduce the cooling load in the summer, and reduce equipment costs. Or, the operating cost can be saved.

Moreover, since visible light is sufficiently transmitted, it is possible to always obtain stable brightness without darkening the room.

Further, by connecting a vacuum pump to the closed space portion to evacuate it, air convection can be prevented and the amount of heat transfer in the closed space portion can be extremely reduced.

Moreover, it is possible to prevent the radiant heat (infrared rays) from escaping from the room during the winter nights, and to save the heating energy.
