Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an energy-saving glass window, and more particularly to an energy-saving glass window that utilizes heat-reflecting window glass.

Prior Art Heat-reflecting window glass is used to improve the efficiency of air conditioning by reflecting sunlight in the summer. Windows that use conventional heat-reflecting glass prevent strong solar radiation from entering indoors in the summer and help improve the efficiency of air conditioning, but in the winter they prevent useful solar energy from entering indoors and are used for heating purposes. This has the disadvantage of increasing fuel consumption.

OBJECTS OF THE INVENTION It is therefore an object of the present invention to overcome the above-mentioned drawbacks of the prior art by providing an energy-saving glass window of simple construction.

Composition of the Invention In order to achieve this object, an energy-saving type glass window according to the present invention includes a shoji in which an ordinary window glass and a heat ray reflective window glass are held parallel to each other with a space between them, and a shoji shoji that holds the heat ray reflective window glass above and below the heat ray reflective window glass of the shoji. It has a structure comprising a slit bored perpendicularly to the surface of the heat ray reflective window glass at the end so as to communicate the space with the outside, and a window frame for holding the shoji at an arbitrary angular position.

Embodiment Referring to FIGS. 1 and 2, which schematically show a front view and a cross section of an embodiment, a shoji 1 has an ordinary window glass 2 and a heat-reflecting window glass 3 arranged in parallel with each other through a gap 4. Hold. The normal window glass 2 is a normal window glass. A slit 5 is made in a part along the upper edge of the heat-reflecting window glass 3 of the shoji 1 and a part along the lower edge of the heat-reflecting window glass 3.
The shoji 1 is communicated with the outside through the shoji 1.

The shoji 1 is held on a window frame 7 by holding fittings 6. The window frame 7 is integrally fixed to the wall W. The illustrated holding fixture 6 has a shaft element that rotatably supports the shoji 1 around a vertical axis of rotation, and a tightening element that holds the shoji 1 at an arbitrary angular position. Although the shoji 1 of the present invention needs to be held at any angular position, it does not necessarily need to be rotatable around a vertical axis.

To explain the function, in the summer, the shoji 1 is held at an angular position where the heat ray reflecting window glass 3 faces outdoors as shown in FIG. By doing so, the solar radiation S is actively reflected by the heat ray reflecting window glass 3, and an increase in the cooling load due to the solar radiation S is prevented.
Also, the air accumulated in the sky 4 inside the shoji 1 is indicated by the arrow M
As shown in , since the heat is automatically discharged to the outside through the slits 5 provided at the upper and lower parts of the shoji 1, an increase in the incident heat indoors from the air 4 is prevented.

In winter, the shoji 1 is normally held at an angular position where the window glass 2 faces outdoors as shown in FIG.
In this state, solar radiation S passes through the normal window glass 2, enters the sky 4, and is reflected by the heat-reflecting window glass 3. Since ordinary glass is opaque to heat rays with long wavelengths, most of the heat rays reflected from the heat ray reflecting window glass 3 are not emitted to the outdoors and warm the air in the sky 4. The warmed air is automatically sent indoors through slits 5 provided at the top and bottom of the shoji 1 as shown by arrow N. Therefore, the indoor air is mixed with the air from the sky 4 and warmed, producing a heating effect by solar heat.

During the intermediate period when the outside temperature is comfortable, the shoji 1 is held in an open angular position to enable outside air conditioning through ventilation and to save energy.

Effects of the Invention The energy-saving glass window according to the present invention uses a shoji that holds a heat-reflecting window glass and an ordinary window glass in parallel with a space between them, and the above-mentioned space is attached to the upper and lower ends of the heat-reflecting window glass of the shoji. Slits are made perpendicular to the heat-reflecting window glass surface so as to communicate with each other, and the shoji is constructed so that it can be held at any angle, so the simple structure allows sunlight to be actively reflected outdoors in the summer. This reduces the cooling load, allows solar heat to be used for heating in the winter, and allows outside air conditioning through ventilation during the middle months when the outside temperature is comfortable.
It has a remarkable energy saving effect.
