DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a first embodiment of the heat insulating self-adjusting wall of the present invention.
In the figure, reference numeral 31 indicates a building wall, and a fixing member 33 is fixed to the building wall 31. One end of a large number of plate-shaped thermosensitive members 35 is fixed to the fixing member 33 at predetermined intervals in the vertical direction.

In this embodiment, the thermosensitive member 35 is made of a shape memory alloy, a bimetal or the like, and the upper surface of the thermosensitive member 35 is plated with, for example, a metal having a large heat absorption coefficient.
The lower surface is plated with a metal having a small heat absorption rate.
In the heat-insulating self-adjusting wall configured as described above, the temperature of the heat-sensitive member 35 is, for example, SAT (Sol-Air T).
When the temperature is about 20 ° C., as shown in FIG. 1, the thermosensitive member 35 projects in a direction substantially perpendicular to the building wall 31, but at 10 ° C. at the SAT temperature.
At this point, as shown in FIG. 2, the tip of the heat-sensitive member 35 is deformed downward, and the air holding layer 37 having a relatively large air holding amount is formed, so that the heat insulating property is enhanced.

At this time, since the upper surface of the heat-sensitive member 35 plated with a metal having a high heat absorption rate becomes the atmosphere side, the heat absorption rate increases. On the other hand, when the SAT temperature reaches about 30 ° C., as shown in FIG. 3, the tip of the heat-sensitive member 35 is deformed upward, and the air holding layer 37 having a relatively large air holding amount is formed. Is enhanced.

At this time, since the lower surface of the heat-sensitive member 35 plated with a metal having a low heat absorption rate is the air side, the heat absorption rate decreases. The above-mentioned SAT temperature is obtained by dividing the value obtained by multiplying the solar radiation absorption rate on the surface of the heat-sensitive member 35 by the amount of solar radiation by the heat transfer coefficient, and adding the outside air temperature to this value.

In the heat-insulating self-adjusting wall constructed as described above, the outer surface of the building wall 31 is provided with the air holding layer 3.
7 is disposed, and the air holding amount of the air holding layer 37 of the heat-sensitive member 35 is determined by the heat-sensitive member 35.
The heat insulating property is increased as the temperature decreases or rises, and the heat insulating property is enhanced. Therefore, it is possible to easily change the heat insulating property drastically in accordance with the outside air temperature.

Further, in the heat-insulating self-adjusting wall configured as described above, since the thermo-sensitive member 35 which is automatically deformed by the temperature change is used, the outside air temperature can be controlled without using a special control device. Correspondingly, the heat insulation can be automatically changed. Further, in the heat-insulating self-adjusting wall configured as described above, for example, a metal having a large heat absorption rate is plated on the upper surface of the heat-sensitive member 35, and a metal having a small heat absorption rate is plated on the lower surface. In addition, it is possible to more reliably maintain the heat insulating property according to the outside air temperature.

Further, since the plate-like heat-sensitive member 35 is directly protruded to the outside, for example, the temperature of the outside becomes high, and the heat-sensitive member 35 shown in FIG.
When the thermo-sensitive member 35 is deformed so as to be perpendicular to the fixing member 33 from the state, the air in the air holding layer 37 can be quickly discharged. FIG. 4 shows the effect of the heat-insulating self-adjusting wall configured as described above on the vertical axis, where the heat transmission ratio (the heat transmission of the wall in the state of FIG. 2 with respect to the heat transmission of the wall in the state of FIG. 1). The horizontal axis indicates the thermal resistance of the building wall 31. The area between the arrows A indicates the effect of the air holding layer 37, and the area between the arrows B indicates the emissivity reduction effect. .

In the embodiment described above, an example was described in which the thermosensitive members 35 were arranged at predetermined intervals in the vertical direction. However, the present invention is not limited to such an embodiment. Needless to say, they may be arranged at predetermined intervals in the horizontal direction. FIG. 5 shows a second embodiment of the heat insulating self-adjusting wall of the present invention. In this embodiment,
One end of a plate-shaped magnetic member 41 made of a magnetic material is connected to the electrode plate 4.
3 so as to be rotatable.

An electromagnetic force means 45 for opening and closing the magnetic member 41 to change the air holding amount of the magnetic member 41 is provided. The electromagnetic force unit 45 is disposed near the magnetic member 41 and measures the temperature of the magnetic member 41.
7, the power supply controller 49 is turned on,
It has a control device 51 for turning off.

That is, in the control device 51, whether the power supply controller 49 is to be turned on or off is stored in advance in accordance with the signal from the temperature sensor 47. In the heat-insulating self-adjusting wall configured as described above, S
When the AT temperature is within a predetermined range of, for example, about 20 ° C., the power controller 49 is turned on, and the magnetic member 41 is separated from the electrode plate 43 by the repulsive force between the electrode plate 43 and the magnetic body 41. Projecting vertically, SAT
When the temperature becomes about 10 ° C. or 30 ° C. and departs from the predetermined temperature range, the power controller 49 is turned off,
As shown in FIG. 6, the repulsive force disappears, and the tip of the magnetic member 41 is dropped downward, so that the air holding amount of the air holding layer 53 increases, and the heat insulating property increases.

With the heat-insulating self-adjusting wall configured as described above, substantially the same effects as in the embodiment shown in FIG. 1 can be obtained.

[0024]

As described above, in the heat-insulating self-adjusting wall according to the first aspect, when the external temperature is at a predetermined temperature, the heat-sensitive member is located substantially perpendicular to the fixing member, and is determined in advance. When the temperature is lower than the set temperature, the heat-sensitive member is positioned so as to be inclined in the same direction with respect to the fixing member, so that the heat insulating property can be significantly changed according to the outside air temperature.

Further, since the plate-shaped heat-sensitive member is directly protruded to the outside, when the temperature of the outside becomes high and the heat-sensitive member is deformed so as to be perpendicular to the fixed member, air is retained. The air in the bed can be quickly exhausted. Claim 2
In the heat-insulating self-regulating wall, when the external temperature is lower than the predetermined temperature, the metal layer having a large heat absorption rate of the heat-sensitive member is located outside, and the external temperature is higher than the predetermined temperature. Sometimes, since the metal layer having a small heat absorption rate of the heat-sensitive member is located on the outside, for example, in winter when the temperature is low,
The temperature of the air-bearing layer is increased by the solar radiation, and in summer when the temperature is high, the temperature rise of the air-bearing layer due to the solar radiation can be suppressed.

According to the third aspect of the present invention, when the outside temperature is out of the predetermined temperature range, the power controller is turned off by the control means, and the repulsive force between the magnetic member and the electrode plate disappears. Since the magnetic member is inclined downward by its own weight and an air holding layer is formed between the magnetic members,
According to the outside air temperature, the heat insulating property can be changed drastically. Further, since the plate-shaped magnetic member protrudes directly to the outside, when the magnetic member is moved so as to be perpendicular to the electrode plate, the air in the air holding layer can be quickly discharged.
