Abstract

PURPOSE:To reflect the insolation during the summer and promote the taking-in of solar energy indoors during the winter by a method wherein a heat ray reflecting windowpane is utilized. CONSTITUTION:A sash 1 holds an ordinary windowpane 2 and a heat ray reflecting windowpane 3 in parallel with a gap 4 therebetween. Slits 5 are respectively cut off at a portion along the upper edge and a portion along the lower edge of the heat ray reflecting windowpane 3 of the sash 1 in order for said gap 4 to communicate with the exterior of the sash 1 therethrough. During the summer, the sash 1 is held at the angular position, at which the heat ray reflecting windowpane 3 is in the outdoor side. Thus, the insolation S is positively reflected by the heat ray reflecting windowpane 3, resulting in preventing the cooling load from increasing. On the other hand, during the winter, the sash 1 is held at the angular position, at which the ordinary windowpane 2 is in the outdoor side. At the state as just mentioned above, the insolation S transmits the ordinary windowpane 2 and enters the gap 4 and then is reflected by the heat ray reflecting windowpane 3, resulting in heating the air in the gap 4. The air heated in the gap 4 is automatically sent out indoors through the slits 5 provided at the upper and lower parts of the sash 1 as indicated with the arrows N.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION 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.

BACKGROUND OF THE INVENTION Heat-reflecting window glasses are used to improve the efficiency of air conditioning by reflecting 11 rays of radiation during the summer. Conventional heat-reflecting windows Windows that use crow 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 Accordingly, it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art by providing an energy-saving glass window of cylindrical construction.

Structure of the Invention In order to achieve this object, an energy-saving glass window according to the present invention includes a shoji that holds an ordinary window glass and a heat ray reflective window glass parallel to each other with a gap therebetween, and a shoji shoji that holds an ordinary window glass and a heat ray reflective window glass in parallel with each other with a gap therebetween. The shoji has a structure including a slit bored in the shoji so as to communicate with the gap, and a window frame for holding the shoji at an arbitrary angular position.

Embodiment 1 FIGS. 1 and 2 schematically show the front and cross sections of the embodiment
Referring to the figure, the shoji 1 holds a normal window glass 2 and a heat ray reflective window glass 3 in parallel with a gap 4 in between. The normal window glass 2 is a normal window glass. A slit 5 is bored in a portion of the shoji 1 along the upper edge of the heat-reflecting window glass 3 and a portion along the lower edge of the heat-reflecting window glass 3, and the space 4 -1- is inserted through the slit 5 through the slit 5. to communicate with the outside of shoji I.

The shoji l is held on the window frame 7 by a holding fitting 6. The window frame 7 is integrally fixed to the wall W. The holding fitting 6 of the 1Δ example has a shaft element for rotatably supporting the shoji l around a vertical axis of rotation, and a tightening element for holding the shoji l 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.

In addition, the air accumulated in the gap 4 in the shoji l is automatically discharged outdoors through the slit 5 provided in a part and the bottom of the shoji l, as shown by the arrow M. 4
This prevents an increase in incident heat indoors.

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 gap 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 reflective window glass 3 are not emitted to the outdoors and warm the air within the void 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 this gap 4 and warmed, producing a heating effect by solar heat.

During the middle of the year when the outside temperature is comfortable, the shoji l 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 gap therebetween, and the heat-reflecting window glass is connected to the gap at the lower position of the shoji. The shoji is structured so that it can be held at any angle with a slit that connects it, so in the summer it actively directs sunlight outside to reduce the cooling load, and in the winter it uses solar heat to heat the room. In the middle of the season when the outside air temperature is comfortable, ventilation is allowed to be used for outside air conditioning, resulting in a significant energy saving effect.
