Description

[Detailed Description of the Invention] [Industrial Application Field] This invention ventilates the attic space by sending air cooled by geothermal heat under the floor to the attic space, thereby keeping the attic space cool in the summer. Concerning the ventilation structure of houses in which people can live.

[Conventional technology]

In conventional houses, the space under the floor and the attic space are separate from each other, and when ventilating the attic space, ventilation holes in the gable walls take in the air and drain the air inside the attic space. into the atmosphere,
In addition, when ventilating the space under the floor, ventilation holes provided in the fabric foundation take in the atmosphere and release the air from the space under the floor to the atmosphere.

[Problem that the invention seeks to solve]

However, in the above-mentioned conventional houses, the air in the attic space heated by solar heat is exchanged with warm air outside, so if the difference between the temperature of the air in the attic space and the temperature of the outside air is small, the heat exchange rate is There is a problem that the effect is not expected because the value is low.

Furthermore, the ventilation means has a problem in that the ventilation capacity is low because the outside air is taken into the attic space by natural air flow, and it is difficult to keep taking in a constant amount of air at all times.

[Means for solving problems]

This invention was made in view of the above-mentioned circumstances, and its means include an intake hole formed in a fabric foundation installed on the ground, and an air intake hole formed in a gable wall or roof for exhausting air from the attic space. exhaust hole and
A hole formed vertically in the ground under the floor, and a bedding material with high thermal conductivity and moisture resistance laid on the ground under the floor including the surface of the hole, one side communicating with the attic space and the other side under the floor. A ventilating pipe that communicates with the internal space of the hole under the floor and extends vertically through the room, and a fan that sends air in the ventilating pipe from the internal space of the hole under the floor to the space in the attic. One of the methods is an intake hole formed in the fabric foundation set on the ground, an exhaust hole formed in the gable wall or roof to exhaust air from the attic space, and a vertical hole formed in the ground under the floor. and a bedding material with high thermal conductivity and moisture resistance laid on the ground under the floor including the surface of the hole, one side communicating with the attic space and the other side communicating with the interior space of the underfloor hole, and a floor material with high thermal conductivity and moisture resistance laid on the ground under the floor including the surface of the hole, and a ventilation pipe installed vertically across the ventilation pipe; a fan that sends air in the ventilation pipe from the internal space of the hole under the floor to the space in the attic; It consists of an exterior wall panel that has an internal ventilation passage that communicates with the attic space and whose lower part communicates with the underfloor space.

[Effect]

In the above means, when the fan in the ventilation cylinder rotates, air taken in from the intake hole of the cloth foundation flows into the space of the hole formed vertically in the ground under the floor. At this time, since the bedding material with high thermal conductivity and moisture resistance is laid on the ground below the floor, including the surface of the hole, the cold heat from the ground is transmitted to the air inside the hole space. cool down. The cooled air is sent into the attic space by the fan through the vent pipe and the ventilation passage, and the warm air in the attic space is exhausted to the outside through the exhaust hole. Ru. As a result, radiant heat is removed and absorbed, lowering the temperature inside the attic space. Furthermore, since the cold space also passes through the ventilation pipes and the ventilation passages of the outer wall panels, the temperature of the room also decreases.

〔Example〕

The first invention will first be described in detail based on the embodiments illustrated below.

In the figure, reference numeral 1 indicates a cloth foundation, and this cloth foundation 1 is fixed to the ground 2. A foundation 3 is fixed on top of the cloth foundation 1, and this foundation 3
An outer wall panel 4 is provided on top of the . Eave beams 5 are provided on these outer wall panels 4, and a roof 6 is provided on these eave beams 5. A floor 7 is provided on the base 3, and a ceiling 8 is provided below the eave sill 5. Further, a gable wall 9 is formed to surround the space under the roof 6.

An intake hole 11 is formed in the cloth foundation 1 to take in outside air into the space under the floor 10. A vertical hole 12 is formed in the ground 2 of the underfloor 10, and the ground 2 of the underfloor 10, including the surface of this hole 12, is covered with a thermally conductive and moisture-proof material made of aluminum foil, aluminum foil-deposited vinyl chloride sheet, etc. High quality bedding material 13
has been installed.

Inside the room surrounded by the outer wall panel 4, there is a ventilation cylinder 15 which has openings 14 at both ends and is hollow inside.
is installed so as to traverse the room, one opening 14 of this ventilation pipe 15 is connected to the space in the attic 16, and the other opening 14 is connected to the space under the floor 10, and the other opening 14 is connected to the space in the attic 16. The ventilation pipe 15 is preferably made of a material with high thermal conductivity so that it can also absorb indoor heat. An auxiliary ventilation cylinder 17 is arranged below the ventilation cylinder 15, and this auxiliary ventilation cylinder 17 allows outside air entering from the intake hole 11 of the cloth foundation 1 to pass through the vicinity of the bottom of the space inside the hole 12. Vent cylinder 1
The air flow is regulated so that it rises in five directions. An exhaust hole 18 is formed in the gable wall 9 below the roof 6.

A fan 19 is installed inside the auxiliary ventilation cylinder 17, and this fan 19 is connected to the auxiliary ventilation cylinder 1.
7 is raised and discharged from an exhaust hole 18 of a gable wall 9 through a ventilation pipe 15 and an attic space 16, and outside air is taken into the space under the floor 10 from an intake hole 11 of a cloth foundation 1. In this way, outside air enters the hole 12 in the underfloor 10 from the intake hole 11 in the cloth foundation 1, ascends through the auxiliary ventilation pipe 17 and the ventilation pipe 15, and enters the space in the attic 16, and then enters the exhaust hole 18 in the gable wall 9. Since the temperature of the ground 2 at the bottom of the hole 12 is considerably lower than the outside air in summer, when the air cooled by the ground 2 below the hole 12 rises inside the ventilation pipe 15, it cools the air in the room. At the same time, the high-temperature air in the attic space 16 heated by the sun's rays is exhausted to the outside.

Next, an embodiment of the second invention will be described based on the drawings. The difference from the embodiment of the first invention is that a ventilation passage 20 is formed inside the exterior wall panel 4, and the foundation 3 is arranged so that the ventilation passage 20 is communicated with the space under the floor 10 and the space in the attic 16. and that ventilation holes 21 are formed under the eaves 5, respectively. As the air in the space in the attic 16 is discharged to the outside by the action of the fan 19, the air in the ventilation path 20 inside the outer wall panel 4 rises and enters the space in the attic 16.
Air flows into the space. As air rises in the ventilation path 20 of the outer wall panel 4, heat is absorbed from the outer wall panel 4 and the outer wall panel 4 is cooled.

Incidentally, outside air naturally enters the space under the floor 10 from the intake hole 11 of the cloth foundation 1, passes through the auxiliary ventilation pipe 17, the ventilation pipe 15, and the ventilation path 20 of the outer wall panel 4, enters the space in the attic 16, and then enters the space in the attic 16, and then enters the space in the attic 16 through the ventilation hole 15. When exiting from 18, there is no need to operate the fan 19.

As shown in FIG. 2, an exhaust hole 18 is provided in the end wall 9.
Instead of forming an exhaust ridge 22 on a part of the top of the roof 6, an exhaust hole 18 is provided on the side of the exhaust ridge 22.
It is also possible to provide exhaust gas. In this case, as in the case described above, the air that enters the space under the floor 10 from the intake hole 11 of the cloth foundation 1 due to the action of the fan 19 passes through the auxiliary ventilation pipe 17, the ventilation pipe 15, and the ventilation path 20 of the outer wall panel 4 to the attic 16. Exhaust hole 1
Go outside from 8.

Further, the fan 19 may be placed inside the ventilation pipe 15 or in a space in the attic 16 instead of being provided in the auxiliary ventilation pipe 17.

The depth of the hole 12 is preferably about 50 to 100 cm, and the ratio of the area of the hole 12 to the area of the floor 7 is 1:1.
A ratio between 15 and 9 to 10 is desirable. Further, the area where the ventilation cylinder 15 contacts the indoor air is preferably large in order to increase the cooling effect. The present invention
It can also be applied to houses with two or more floors.

Note that in winter, since there is no need to move air within the vent pipe 15, the vent pipe 15 may be closed with a suitable closing member.

〔Effect of the invention〕

As is clear from the above explanation, geothermal heat is used to cool the outside air and cool the warm air in the attic space, which increases the heat exchange rate and improves the cooling effect. In addition, since outside air is introduced into the space under the floor using a fan, a constant amount of ventilation can be achieved at all times. Furthermore, by allowing air to pass through the inside of the outer wall panel, the inside of the wall can be cooled, making it possible to live even cooler in the summer.
