Description

[Detailed description of the invention] Industrial applications This invention relates to a detached house with variable heat insulation.

Conventional technology Traditional houses are broadly divided into insulated and non-insulated types.

In general, insulated buildings have the disadvantage that while it is difficult for heat to escape from inside, it is also difficult for heat to enter from outside. In other words, it is better not to emit heat at night in winter, but it also insulates during the daytime when the sun is shining so that no heat is absorbed. During the summer daytime, solar heat is not allowed to enter the building, but at night, the problem arises that the heat from inside the building cannot escape.

Insulated houses do not necessarily save energy because of this contradiction.

In uninsulated houses, the opposite phenomenon occurs as in insulated houses, and energy savings are not achieved.

In particular, the sealing of wall cavities with insulation materials is a problem in the housing industry, as the difference in temperature between inside and outside creates condensation water, which accelerates the corrosion of wood.

In particular, corrosion of the foundation is a problem due to insufficient ventilation at the base.

Problems to be Solved by the Invention Therefore, the present invention solves the problems of promoting ventilation in the base, ventilation in the wall cavity, and heat insulation in order to eliminate the drawbacks of the prior art.

Means for solving the problem The foamed resin L-shaped insulation material (1) has many grooves (2) in an L-shaped direction, and this L-shaped insulation material (1) is used as a base (13).
A narrow board is fastened to the outside of the pillar (16) and a stud (17), and the outer wall (4) is also fastened.

On the inside, there is a heat insulating material (3) in contact with the inner wall, and between this heat insulating material (3) and the outer wall (4) there is an air space (
12) is formed, and a spacer is inserted between the foundation (14) and the base (13) to maintain a gap.

Furthermore, inside the building, the duct (5) is connected to the underfloor space (8).
) and the attic space (7), an intermediate ventilation fan (6) is provided between the duct (5), and both sides of the outer wall (4) are structured to prevent air movement, and the attic ventilation opening (10 ) and the underfloor ventilation opening (11) shall be openable/closable.

Function The present invention is a variable heat insulating wall that absorbs heat from the outside world but does not let it out, distributes the heat through air circulation in the indoor wall cavity, and protects the foundation from corrosion by providing ventilation around the four peripheries of the foundation.

EXAMPLES Below, the present invention will be described in detail based on the drawings.0 Starting from the winter, the underfloor ventilation opening (11) and the attic ventilation opening (10) are closed.

Now, if the sun is shining from the right direction in Figure 1, then
The outer wall (4) is heated, and eventually the air in the air layer (12) is heated, and the high-temperature air rises and flows into the attic space (7), whereupon the cold air inside the building flows into the air layer (12). do.

In this way, heat can be absorbed into the building by air convection.

On the other hand, on the non-solar surface, the outer wall (4) is cooled and the air layer (1
2) The air inside is also cooled and descends. The descending heavy air has no place to flow out, so it becomes still air, and the insulation material (3
) and insulating the entire wall.

In this way, heat is collected in the attic space (η, but as it is, the high-temperature air cannot descend and warm the room. Therefore, the intermediate ventilation fan (6) is driven and the high-temperature air is transferred to the underfloor space (η) through the duct (5). 8).

From the partition cavity (9), mixed air from the underfloor space (8) and the attic space (7) flows into the attic space (7).

The heat collected in this way is forced to circulate through the intermediate ventilation fan (6) to warm the building.

In other words, the wall becomes a non-insulated wall on the solar irradiated surface, and the wall becomes an insulated wall on the non-solar irradiated surface. Such walls are called variable insulation walls.

At night, all the walls act as insulating walls, just like non-solar surfaces, and work to prevent heat from escaping.

In the summer, although not shown, the underfloor ventilation opening (11) and the attic ventilation opening (10) are opened to release the collected hot air to the outside to cool the building.

As explained in detail about the invention, it is a variable insulation house that can heat the house with a small electricity bill in the winter, stay naturally cool in the summer, and protect the foundation with airflow, contributing to resource and energy conservation. be.
