In this specification, front and rear are based on FIG. 2, and the front refers to the left side in FIG. 2, and the rear refers to the right side in the same figure.

Prior Art and its Problems Conventionally, pergolas have been installed only for the purpose of shading, and it has never been thought of to use them to heat indoors in winter.

The purpose of this invention is to provide a pergola that can heat indoor rooms in winter using solar heat.

Means to solve the problem The pergola according to this invention can be installed on the outside of the wall of the building.
It is equipped with a louver eave that protrudes forward and is swingable up and down around the rear end, and the louver eave has a plurality of movable vanes that can rotate freely, and one side of the vane has a solar heat absorption film. is formed, and a sunlight reflecting film is formed on the other surface, and the blade plate is provided with a heat pipe portion, and a portion of this heat pipe portion is embedded in the wall.

Embodiment An embodiment of this invention will be described below with reference to the drawings.

All members or parts designated by the same reference numerals throughout the drawings are the same.

Example 1 This example is shown in FIGS. 1-4. This pergola consists of a louver eave 2 provided to protrude forward from a wall 1 of the building, and columns 3 supporting the louver eave 2 at both ends of its front edge. The louver eaves 2 includes a front frame member 4 and a plurality of rotatable movable blades 5 provided in parallel between the front frame member 4 and the wall 1. At both end faces of the front frame member 4, bar-shaped protruding members 6 are provided that protrude on both left and right sides. The vane plate 5 is provided with a heat pipe section 7 on one surface thereof. The heat pipe section 7 is provided on one side of the blade plate 5, and both front and rear ends thereof are connected to the blade plate 5.
A circular tube 8 that is joined by welding, brazing, etc. in a state that protrudes forward and backward than the circular tube 8, and a hollow spherical portion 8a that is provided at both the front and rear ends of the circular tube 8 so as to be continuous with the circular tube 8 and that closes the openings at both ends. 8b, the inside of which is evacuated and filled with a working fluid (not shown). No wick is provided inside the circular tube 8. The spherical parts 8a and 8b are rotatably inserted into spherical recesses 9 and 10 provided in the rear surface of the front frame member 4 and the wall 1, respectively, and are fixed to the rear surface of the front frame member 4 and the wall 1 with screws 12. The two falling-off prevention plates 11 prevent falling from the recesses 9 and 10. Therefore, the vane plate 5 is rotatable around the circular tube 8. Moreover, each blade plate 5 is adapted to be rotated in conjunction with each other by a known interlocking mechanism. A sunlight reflecting film 13 made of a white coating is formed on the surface of the vane plate 5 to which the circular tube 8 is attached, and includes the circular tube 8 . When the vane plate 5 is made of aluminum or aluminum alloy, an anodized film may be formed instead of the white coating. A solar heat selective absorption film 14 is provided on the other surface of the vane 5. The solar heat selective absorption film 14 may be provided by subjecting the vane 5 itself to a solar heat selective absorption film treatment, but an aluminum foil or an aluminum thin plate that has been subjected to a solar heat selective absorption film treatment is attached to the vane board using an adhesive or a pressure-sensitive adhesive. It is convenient to attach it to 5. In particular, a coiled aluminum foil is prepared that has one side treated with a solar heat selective absorption film, the other side coated with an adhesive, and this side covered with a release paper, and this is arranged to match the surface area of the vane 5. It is best to cut it to size and use it. In some cases, an aluminum vapor-deposited synthetic resin film treated with a solar heat selective absorption film may also be used.
Although the solar heat selective absorption film 14 is generally smooth, it may have a corrugated longitudinal section in order to increase its surface area. The characteristics of the solar heat selective absorption film are that the solar absorption rate α is 0.85 or more,
A material with an emissivity ε of 0.3 or less is preferable. An arc-shaped elongated hole 15 is bored in the upper part of the strut 3, passing through the strut 3 in the left-right direction and extending vertically.The rod-shaped protruding members 6 at both ends of the front frame member 4 are loosely inserted into this elongated hole 15. The front frame member 4 is forced to move up and down within the range of the elongated hole 15. Therefore, the vane plate 5 is vertically swingable around the spherical portion 8b at the rear end of the circular tube 8, and the louver eaves 2 is also vertically swingable around the rear end. Further, the rod-shaped protruding member 6 can be fixed at any position within the elongated hole 15.

Such a pergola is used for indoor heating in winter as follows. That is, the rod-like protruding members 6 at both ends of the front frame member 4 are positioned at the lower ends of the elongated holes 15, so that each blade plate 5 is tilted forward and downward, and the solar heat selective absorption film 14 surface of the blade plate 5 is exposed to the sun. Each blade plate 5
(See Figures 2 and 3).
The working fluid flows into the front spherical portion 8a of the circular tube 8. Then, the sunlight S from outdoors O hits the solar heat selective absorption film 14, and as a result, with the help of the action of the solar heat selective absorption film 14, which absorbs heat well but radiates little heat, it is sufficient to reach the vane plate 5. The heat is conveyed. Due to this heat, the working fluid remaining in the front end spherical part 8a of the circular tube 8 is heated and vaporized and reaches the rear end spherical part 8b, where the gaseous working fluid liquefies heat and flows forward. The heat released when the gaseous working fluid liquefies is absorbed by the wall 1
is transmitted to indoor I through wall 1, and is radiated to indoor I.
is heated.

In the summer, each blade 5 is rotated to face the sunlight reflecting film 13 upward, and the front frame member 4 is raised to tilt each blade 5 downward toward the rear (Fig. 4). reference). Then,
The working fluid in the circular tube 8 flows into the rear end spherical portion 8b and stays there. Therefore, the heat pipe section 7 does not operate as it does in winter, and solar heat from the outdoors O is prevented from entering the indoors I. Moreover, the working fluid in the rear end spherical part 8b is heated and vaporized by the heat stored in the wall 1 by the sunlight S, and reaches the front end spherical part 8a, where the gaseous working fluid radiates heat and liquefies. Because it flows backwards, wall 1
The heat stored in the room is radiated to the outside O, and can be prevented from being radiated to the indoor I. Furthermore, due to the sunlight reflecting action of the sunlight reflecting film 13, the sunlight S
Even if most of the heat is reflected and a small amount of heat is stored in the slats 5, since the surface of the solar heat selective absorption film 14 faces downward, the heat will not be radiated below the louver eaves 2. Louva eaves 2
The area below can be used as a shade to keep it cool.

Example 2 This example is shown in FIG. In this pergola, the circular pipe 8 of each blade plate 5
The front end of the header 21 is straight, closed at both ends, and connected in communication with a front header 21 having a vacuum inside. Both ends of the front header 21 are loosely inserted into the long holes 15 of the support column 3. Further, the rear end of the circular tube 8 is connected in communication with a rear header 22 whose both ends are bent rearward and whose interior is vacuumed. Hollow spherical portions 23 are provided at the rear ends of the bent portions at both ends of the rear header 22, and these spherical portions 23 are fitted into recesses 24 provided in the wall 1. Then, the circular pipe 8, the front header 21,
A heat pipe section 7 is formed by the rear header 22 and the bulbous section 23. Rear header 2
2 is supported by support members 25 at both ends. Although not shown, the support member 25 consists of a vertical member that is extendable and can be fixed at a desired position, and an annular member provided at the upper end of the vertical member, and the rear header 22 is inserted through the annular member. There is. This pergola is used for winter indoor heating in substantially the same manner as in Example 1. Also, in the summer, in substantially the same way as in the first embodiment, solar heat is prevented from entering indoors, and the heat stored in the wall 1 is radiated outdoors.

FIGS. 6 and 7 show modified examples of the vane.

The vane plate 35 shown in FIG.
The heat pipe section 37 is comprised of a circular tube 38 that is fitted into a groove 36 provided on one surface of the heat pipe section 5.

The vane plate 45 shown in FIG.
A hollow portion 46 with a circular cross section extending in the length direction is provided in the center of the width direction of the heat pipe 5, and this hollow portion 46 is used as a heat pipe portion 47.
Such a wing plate 45 is made by extrusion molding.

Effects of the invention As described above, according to the pergola according to this invention, indoor space I can be heated using solar heat in winter. Furthermore, in the summer, it is possible to prevent solar heat from entering indoors and to radiate heat stored in the walls of the building to the outside.
