Description

[Detailed description of the invention] "Field of industrial application" This invention relates to a curtain wall used as an outer wall of a building.

``Prior Art'' Curtain walls are generally constructed by constructing blind members 1 and mullions 2 in the form of a lattice on the outer wall of a building, as shown in Figure 2. Generally, glass is fitted into the waist part 3, and the part facing the floor 5 and ceiling 6 is called a waist part 3, as shown in FIG. 3, and an opening 4 that functions as a window is provided above the waist part 3.

``Problems that the invention aims to solve'' Conventional curtain walls have a structure that simply shields the indoors and outdoors with glass, so they have poor insulation performance. As a result, there is a drawback that the room temperature is greatly affected by the outside temperature. In other words, when the outside temperature is low, the room temperature also drops, which has the disadvantage of consuming a large amount of energy for heating.

Furthermore, when the outside air temperature is high, the room temperature also becomes high, which has the drawback of requiring a large amount of energy for cooling.

``Means for solving the problem'' In this invention, at least the waist part of the curtain wall is fitted with a heat insulating panel on the indoor side and a transparent panel like glass on the outdoor side. It has a two-layer structure, and a cavity is formed between the heat insulating panel and the transparent panel, and this cavity is divided into an indoor side and an outdoor side by a partition wall formed by a plurality of rotating blades.

One of the rotating blades is formed as a heat reflecting surface, and the other is formed as a heat absorbing surface. By rotating this rotary vane so that the heat-absorbing surface faces the indoor side, it is possible to provide the property of discharging indoor heat to the outside. Furthermore, by arranging a heat reflecting surface facing the indoor side, it is possible to introduce the outside temperature into the room.

In addition, in this design, ventilation holes are formed at the top and bottom of the two chambers divided into two by the rotating blade, and a shutter is installed in the ventilation hole, and the shutter can be opened as needed to allow the rotating blade to operate. Outside air and indoor air circulate through the partition wall, which promotes heat exchange.

``Example of the invention'' Figure 1 shows an example of a curtain wall according to this invention. In Fig. 1, 1 is a blind piece, 2 is a mullion piece, 3 is a waist part, and 4 is an opening, which are the same as the conventional one.

In this design, the waist part 3 of the curtain wall
In this step, a heat insulating panel 7 is fitted on the indoor side, and a transparent panel 8 is fitted on the outdoor side. Glass is generally used as the transparent panel 8. A cavity is formed between a heat insulating panel 7 and a transparent panel 8, and a plurality of rotating blades 9 are arranged in this cavity to form a partition wall.

In this example, a band-shaped blade 9 made of extruded aluminum material, for example, is provided in parallel with the blind material 1. The blade 9 is provided with a shaft 9A at its center in the width direction, and the blade 9 is rotatably supported by the shaft 9A. A flexible airtight material 11 is attached to each side of the rotating blade 9, and this airtight material 11
are brought into contact with the ends of adjacent rotating blades 9, and this contact creates an airtight structure between the blades 9, and the rotating blades 9 form a partition wall. Airtight materials 12 and 13 are provided on the lower and upper sides of the open material 1, and the edges of the rotary blades 9 are pressed against the airtight materials 12 and 13, so that the upper and lower ends of the partition wall are also airtight on the indoor side and the outdoor side. It has a certain structure.

Reference numeral 14 indicates a rotation operating device for rotating the rotary blade 9. This rotation operation device is, for example, a blank material 1.
A shaft 14A is rotatably supported, and a handle 14B is attached to a portion of the blind member 1 that projects outside. On the other hand, a shaft 14C is rotatably supported outside the end of each rotary blade 9, and shafts 14A and 1
4C by, for example, a worm gear 14D, and the shaft 9A of each rotating blade 9 and the shaft 14.
C is also connected by a worm gear 14D,
The rotating blade 9 can be rotated by rotating the handle 14B.
Therefore, by appropriately selecting the rotation angle position of the rotary blade 9, it is possible to set the spaces 15 and 16 in a state where they communicate with each other and a state in which the partition walls are shielded.

One surface 9B of the rotating blade 9 is, for example, mirror-finished to serve as a heat-reflecting surface, and the opposite surface 9C is, for example, coated with black matte coating to serve as a heat-absorbing surface. The reflective surface 9B and the heat-absorbing surface 9C of each rotating blade 9 are connected to each worm gear 14D so as to be aligned and face the outdoor side OUT and the indoor side IN.

In this way, a partition wall is formed between the heat insulating panel 7 and the transparent panel 8 by the rotating blades 9, and this partition wall forms two cavities 15 and 16 between the indoor side IN and the outdoor side OUT. do.

Ventilation holes 19 communicating with the indoor and outdoor areas are provided on the lower and upper sides of these two empty rooms 15 and 16, and shutters 17A and 17 are provided in each ventilation hole 19.
B, 18A, and 18B are provided. These shutters 1
Although 7A, 17B and 18A, 18B are not particularly shown, they have a structure that can be controlled to open and close by a drive source such as an electromagnetic solenoid.

The ventilation holes 19 communicate with the two empty rooms 15 and 16, respectively, and the shutters 17A, 17B, 18A, 18
By opening B, a vacant room 15 formed on the indoor side communicates between the attic on the lower floor and the room on the upper floor. Moreover, the empty chamber 16 on the outside of the room communicates with the outside air.

On the other hand, in this embodiment, the opening 4 is also made of glass 21, 2.
2 is fitted on the inside and outside to form a double structure, and a blind 24 is installed in the empty space 23 formed by the two glasses 21 and 22.

Further, in the opening 4, ventilation holes 19 are formed above and below the indoor side and the outdoor side of the empty room 23, and these ventilation holes 1
9 and shutters 17A, 17B and 18
The case where A and 18B are provided is shown.

The frame 25 supporting the transparent panel 8 of the waist portion 3 and the glass 21 on the indoor side of the opening 4 has one end connected to the mullion 2 by, for example, a hinge, and can be opened as necessary. Therefore, the frame 25 that supports these transparent panels 8 and glass 21 is made of airtight material 26.
It has a structure in which it is pressed into contact with the open material 1 through the.

"Operation of Example" For example, when the outside temperature is low like in winter, the waist 3
Then, the outdoor shutters 18A and 18B of the opening 4 are closed. When exposed to sunlight, the rotary blade 9 is rotated so that the heat absorbing surface 9C faces the outdoor side, and the rotary blade 9 is warmed by sunlight. At the same time, when the indoor side shutters 17A and 17B of the waist part 3 are opened, the air warmed in the empty room 15 moves upward and flows into the room, thereby warming the room.

As a result, it is possible to obtain the characteristic of taking in solar energy indoors.

When there is no sunlight, the shutters 17A, 17B and 18A of the waist 3 and opening 4,
18B is closed to stop the movement of air, the outside air and the room are shielded by the heat insulating panel 7 and the transparent panel 8, and the temperature inside the room is prevented from being released to the outside.

On the other hand, when the outside temperature is high and the sunlight is strong, such as in summer, the reflective surface 9B of the rotary blade 9 is operated so as to face outdoors. As a result, sunlight incident from outside is reflected by the reflective surface 9C of the rotary blade 9, thereby preventing heat from entering the room. When sunlight hits strongly, the indoor side shutters 17A and 17B of the waist 3 and opening 4 are closed, and when the outdoor side shutters are left open, the space between the vacant rooms 15 and 16 is shielded by the rotary blade 9. The air warmed in the empty room 16 rises and is exhausted to the outside through the upper ventilation hole 19, forming an air flow rising through the empty room 16 from the bottom to the top. The rotating blades 9 are cooled by this air flow,
The amount of heat that enters the room can be reduced.
At the same time, since the indoor shutters 17A and 17B are closed, the cold air generated by the air conditioner is prevented from escaping to the outside, providing the advantage that the energy required for air conditioning can be reduced.

Shutters 17A, 17B and 18 of opening 4
By opening A, 18B and the rotating blade 9 as necessary, indoor air and outside air can be mixed and passed through the empty room 23, and the indoor air can be ventilated. Also, on summer nights, the rotary blade 9 is shielded and the shutter 17 of the waist 3 is closed.
By opening all of A, 17B, 18A, and 18B, indoor heat can be absorbed by the heat absorption surface 9C of the rotary blade 9 using air as a medium, and can be released to the outside air from the reflection surface 9B. At this time, ventilation can also be performed by opening the rotating blades 9.

"Effect of the invention" As described above, according to this invention, one surface of the rotary blade 9 is the reflective surface 9B, and the other surface is the heat-absorbing surface 9B.
C, the rotary blade 9 is rotated by the rotary operation device 14, and the reflective surface 9B and the heat-absorbing surface 9C can be freely operated to face outdoors, so when the outside temperature is low, such as in winter. The heat absorbing surface 9C of the rotary blade 9 is directed outdoors to allow the rotary blade 9 to absorb solar heat, and this heat can be introduced into the room by the air flowing through the ventilation hole 19.

Also, when the outside temperature is high like in summer, the rotating blade 9
By orienting the reflective surface 9C toward the outdoors, it is possible to reflect heat from the outside and prevent heat from entering the room. Therefore, according to this invention, it is possible to minimize the influence of outside temperature and create a building that consumes less energy.

Furthermore, since the opening 4 also has a double glass structure, it can be reliably insulated from the outside air. Furthermore, a blind 2 is installed between the glasses 21 and 22.
4, it is possible to block external light. As a result, direct sunlight in the summer can be prevented from entering the room, and in this respect as well, the effect of saving energy for cooling can be achieved.

Further, shutters 17A, 1 are attached to the waist 3 and the opening 4.
Because it has a structure with 7B, 18A, and 18B,
Shutters 17A, 17B, 18A, if necessary.
There is also an advantage that ventilation can be performed by opening 18B and unblocking the rotary vane 9.

Furthermore, if one side of the waist part 3 and the opening 4, that is, the frame 25 that supports the transparent panel 8 and the glass 21, is constructed so that it can be opened and closed by a hinge, the interior can be cleaned and maintenance can be facilitated. is obtained.
