2. Description of the Related Art Conventionally, in a building such as a house, a heat insulating material is inserted between an inner wall and an outer wall in order to enhance the effect of heating the room.
Even though it is not affected by the cold weather outside, it has a structure that prevents the heat inside from escaping to the outside. For example, there is one that inserts glass wool or the like between the inner wall and the outer wall to exert a heat insulating effect. In addition, there is a building in which a space is formed between the inner wall and the outer wall, and warm air is passed through the space. In this building, an inner wall material is attached along the inner surface of a pillar, a plate-shaped heat insulating material is attached along the outer surface of the pillar, and an outer wall material is attached on the outer surface.

A conventional building having a heat insulating structure in which glass wool or the like is simply inserted between the inner wall and the outer wall has a gap between the glass wool or the like and a pillar, and Could not be completely shut off. For this reason, warm air easily escapes, and heating costs increase. Also, to form a space between the inner wall and the outer wall,
When a plate-shaped heat insulating material is attached along the outer surface of the pillar, if the heat insulating effect is to be increased, it is necessary to attach a thick heat insulating material, but the wall becomes thick and the cost becomes high. Further, it is difficult to attach the heat insulating material.

[0004] Therefore, an object of the present invention is to provide a wall structure of a building having an air circulation space and having an excellent closed structure without increasing the thickness of the wall of the building.

In addition, along with the cloth foundation 12, the cloth foundation 12 and the heat storage unit 14
The recessed line 16 is formed by. A large recess 18 is formed in a part of the recess 16.

A building 10 is constructed on a cloth foundation 12. Floor material is spread on the floor surface of the building 10 to form the floor 20,
An inner wall material is stretched over the inner wall to form an inner wall 22. A ceiling material is stretched on the ceiling surface to form the ceiling 24. The floor 20 is kept at a predetermined interval so that air flows between the floor 20 and the heat storage unit 14. This interval is the floor passage 26a for air. Meanwhile, the heat insulating material 28 covers the inner wall 22 and the ceiling 24. The inner wall 22 and the heat insulating material 28 form a wall flow path 26b with a predetermined space therebetween. Both the ceiling 24 and the heat insulating material 28 form a ceiling flow path 26c with a predetermined space therebetween. It has a closed structure so that air does not leak from the heat insulating material 28 to the outside. Cloth foundation 1
A sealed structure is also provided between the heat insulating material 28 and the heat insulating material 28.

A heat collector 42 is provided on the roof surface on the south side of the roof 40 of the building 10. In order to supply the air in the ceiling flow path 26c to the heat collector 42, the ceiling flow path 26c and the heat collection space 45 are connected by the supply path 48.

On the other hand, an outer wall member 34 is attached to the outside of the furring strips 32 ... (See FIG. 3). As described above, the inner wall 22 and the heat insulating materials 28a and 28b form the wall flow path 26b.

The floor 20 is constructed by crossing the conventionally known large pulls and joists and laying a floor material 19 thereon. Conventionally, the large pull is supported by the floor, but in this embodiment, it can be supported by the upper surface of the heat storage unit 14. Therefore, the construction of the floor 20 is easy.

A communication pipe 52 extending from the upper portion of the heat collector 42 to the recess 18 is provided to send the air warmed by the heat collector 42 to the recess 18 of the recess 16. A circulation fan 54 as a feeder is arranged near the heat collector 42 of the communication pipe 52. When the circulation fan 54 is driven, the air warmed by the heat collector 42 is sent to the recess 18 of the recess 16. The circulation fan 54 is controlled by a known electric means so as to be driven when the temperature of the heat collector 42 reaches, for example, 20 degrees. The circulation fan 54 uses a solar cell as a drive source. Therefore, when the temperature of the air in the heat collector 42 rises due to the sun, the electricity is also stored in the solar battery that drives the circulation fan 54.

The building 10 has a second floor portion 2F. The second floor portion 2F is composed of a floor 60 and a partition wall 62. The floor 60 and the partition wall 62 are also provided with flow passages similar to the floor flow passage 26a.
The flow path of the floor is 60a, and the flow path of the partition wall 62 is 62a. Each of the flow channels 60a and 62a constitutes a flow channel that communicates with the wall flow channel 26b and the ceiling flow channel 26c. In addition, the wall channel 26b, the ceiling channel 26c, and each channel 60 of the building 10.
The a and 62a are covered with the heat insulating materials 28a and 28b, and have a closed structure so that air does not leak.

FIG. 4 shows a modification of the wall structure. In this example, when the first heat insulating material 28a is fitted between the pillars 31, ...
Positioning is performed by fixing 0 and 70 with nails or the like.

The air flow in the building 10 constructed as described above will be described. When the temperature of the air inside the heat collector 42 rises to a predetermined temperature, for example, 20 degrees due to the sunlight,
The circulation fan 54 starts driving. Then, the warmed air is sent to the recess 18 via the communication pipe 52. On the other hand, when the warmed air in the heat collector 42 is withdrawn,
The heat collecting space 45 in the heat collector 42 becomes negative pressure, and the check valve 50
Opens, and the air in the wall channel 26b and the ceiling channel 26c is sucked. Air is circulated by this suction force and the supply force of the circulation fan 54. That is, the air sent to the recess 18 fills the recess 18 and the recess 16 and warms the floor 20. Air also flows between the heat storage unit 14 and the floor 20. At this time, the heat storage unit 14 is also warmed.

The air in the groove 16 and the recess 18 rises in the wall passage 26b and reaches the ceiling passage 26c. On the other hand, the second floor portion 2F communicates with the flow passage 60a of the floor 60 and the flow passage 62a of the partition wall 62 and circulates to the ceiling flow passage 26c.

When the temperature of the heat collecting space 45 in the heat collector 42 falls below 20 degrees, for example, the driving of the circulation fan 54 is stopped. However, the entire building 10 is surrounded by warm air inside the heat insulating material 28. Further, even after the circulation fan 54 is stopped, the heat is stored in the heat storage unit 14 and is warm, so that the heat is radiated from the heat storage unit 14 and the entire building 10 can be kept warm. At night,
Even if the temperature of the air in the heat collecting space 45 of the heat collector 42 decreases, the check valve 50 exists, so that cold air does not circulate.

The heat storage section 14 is shielded from the outside air through the cloth foundation 12 and the recessed section 16, and the heat storage section 14 does not extremely cool because of the presence of earth and sand. Further, as described above, since warm air passes through the floor, walls, and ceiling of each room of the building 10, the entire building 10 can be heated. Further, the air circulates in the closed circulation path and does not take in cold outside air, which is efficient. Furthermore, since the indoor air that has been warmed up is covered with the heat insulating material 28 and the air layer (the floor channel 26a, the wall channel 26b, and the ceiling channel 26c), it has an excellent heat insulating effect and does not cool. .

The heat collector 42 is preferably provided on the roof on the south side. Further, the communication pipe 52 may be provided in the wall. Further, in the above embodiment, when the sun does not shine, or when the air is not warmed by the heat collector 42 at night or the like, the air is heated using a heating means such as a stove in the recess 18, It is possible to heat the entire building 10 and store heat in the heat storage unit 14.

In the above embodiment, the method of use in the winter is explained, but it is preferable to use it in the night in summer. That is, in the summer night, the heat collector 42
When the temperature of the air in the heat collection space 45 has dropped, the temperature of the room can be lowered by circulating the cooled air.

Although the heat insulating material 28 has a double structure in the above embodiment, it may have a triple structure, a quadruple structure, or the like. In this case, the number of heat insulating materials fitted between the pillars and the number of heat insulating materials located outside the pillars may be appropriately distributed. Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. .

[0023]

Since the present invention is constructed as described above, the wall structure of a building can be made a closed structure, and a building having an excellent heat insulating effect can be constructed. In addition, heat insulation of a multiple structure can be achieved. Among the materials, by fitting the inner heat insulating material between the pillars, it is possible to realize a wall structure having an excellent heat insulating effect without increasing the thickness of the entire wall. .
