For flow fins.

[0002]

2. Description of the Related Art First, a conventional ventilated house will be described. As shown in FIG. 11, a ventilation wall A is provided between the inside of the outer wall of the building, under the roof, and the internal structure space C of the building to form an air flow path B. At the lower part of the side wall of the building, an in-wall airflow fin D is attached so that air flows from the internal structure space C of the building toward the air flow path B but does not flow in the opposite direction. The air flow fins DD are mounted in the wall so that air flows from the air flow path B to the structural space C of the building but does not flow in the opposite direction.

[0003] Airflow fins D are also provided under the roof below the ventilation wall A so that air flows from the internal structure space C of the building toward the air flow path B and does not flow in the opposite direction. mounting, also from the internal structure space C of the building on top of the ventilation wall a under the roof, air is flow toward the air flow path B
However , a bidirectional opening E is provided so that air can flow in the opposite direction.

[0004] Fins G and F, which are opened in summer and closed in winter, are attached to the ridge or the back of the hut and the base. It is assumed that the fins G on the attic have taken measures against rain.

In the above-described structure of the ventilation house, in the summer, the air in the air passage B is heated by the radiant heat received by the outer wall of the building, and rises in the air passage B, so that the air flow in the one-way wall on the upper side wall. Through the fins DD, the air flows into the airflow passage B under the roof via the airflow fins D in the one-way wall under the roof. Further, the hot air is discharged from the fins G in the attic to the outside through the two-way opening E in the upper part of the roof through the air passage B under the roof.

The hot air in the internal structure space C is sucked into the ascending airflow in the air passage B in the side wall portion through the fins D in the one-way wall .

Under the floor, the underfloor airflow fins F are opened, so that fresh air outside passes through.

[0008] In this manner, the hot air that has absorbed the radiant heat received by the external side wall of the building and the hot air in the internal structure space C are released to the outside as an ascending airflow that rises in the air passage B, so that the building internal structure space C is discharged. This is to reduce the cooling load.

In winter, the air passage B on the south side of the building has an updraft as in the case of summer, but the fins G in the attic are closed, so that the air heated by the radiation cannot flow out of the building. Instead, on the north side of the building, the temperature of the air flow path B drops and stagnates or descends. Hot air from the south side descends along the ventilation wall A from above, but the fins DD inside the one-way wall automatically close, so that they do not enter the air passage B. Therefore, dew condensation does not occur on the inner surface of the outer wall.

[0010] The hot air circulates from the south side to the north side to reduce the heating load of the internal structure space C.

Further, since the underfloor airflow fins F under the floor are closed, cold air does not enter from outside.

However, the conventional ventilation house has the following defects. In the summer, all the underfloor airflow fins are opened, so that the cold fresh air outside does not flow into the internal structure space C and passes through it, and the cooling load reduction efficiency is poor.

Further, since the under-floor air fins, the in-wall air fins, and the attic air fins have the same shape and are rectangular, there are the following defects. FIG. 9 is a diagram showing a conceptual diagram of the structure of a conventional fin. When the fins close,
Since the airtightness is ensured between the p-side surface on the front side and the q-side surface on the opposite side of the fin, an air circulating portion r is required, in which the airtightness maintaining surfaces do not overlap. Therefore, in the air circulation part r,
A gap is forced between the flow hole and the fin body . Therefore, the airtightness of the fin is extremely poor. Since the outer shape of the fin is rectangular, the mounting process is complicated. In particular, if the accuracy in the horizontal and vertical directions is not ensured, the fin body is opened and closed smoothly due to the balance opening and closing due to its own weight. FIG.
FIG. 2 is a sectional view of a conventional rectangular fin. Since the fin body is provided in the meandering air passage, the thickness of the entire fin becomes large, and the fin does not fit within the thickness of the heat insulating material. Therefore, it cannot be installed in a factory in terms of transportation, and it is installed on site. It is also difficult to ensure the mounting accuracy. Since the fin body is provided in the meandering air passage as described above, the dust that falls down the air passage makes the opening and closing of the fin body slightly uncertain. Therefore, a dust receptacle 113 as shown in FIG. 10 must be provided. Further, bearings 118 are disposed on the shaft portions on both sides. Therefore, the structure becomes complicated and the cost increases.
When the mounting angle becomes flatter than 45 °, the fin
The body itself loses its balance and is always open.

The present invention has been made in view of these problems.

A rotation axis that passes above the center of gravity of the cross section of the body is inserted in parallel with the surface of the fin body, and set on the lower side from the middle of the opening of the fin seat.
When the fins are mounted vertically with support
The fin body always has an opening of about 10mm between it and the fin seat.
And open it in response to a breeze from the opposite side of the fin body.
Keep the balance so that the release area is increased, the fin seat is
It is a molded product with a cavity.
Has means to control opening and closing of fins with net and cam
Air fins under the floor or fins behind the hut
The gist is that

Here, the under-floor air fins and the under-roof air fins are the same, and the under-floor air fins are used from outdoors to indoors.
The airflow fins behind the hut are installed so that the air flows from indoors to outdoors.

Next, the operation will be described.

FIG. 1 is a diagram showing ventilation in hot and hot weather.

The magnet of the underfloor airflow fin F is released. The underfloor air fins F on the cold air side are opened by the slight wind pressure from the cold air that does not receive outdoor radiation, and the underfloor air fins F on the cold air side receiving the radiation receive the wind pressure on the contrary, so they close automatically. It does not let cool air escape from under the floor.

The cold air that has flowed under the floor is on the side receiving radiation,
On the opposite side, it passes through the double air passages B ₁ and B ₂ to become an ascending air flow, merges with the warm air that has passed through the air passage B ₁ under the roof, and discharges outside through the open hut air flow fins G. Is done. In this way, the cool air naturally convects to reduce the cooling load.

FIG. 2 is a diagram showing ventilation in cold weather.

The underfloor airflow fins F are closed both on the side receiving the radiant heat and on the opposite side by the action of the magnet.

The air in the air passage B ₁ on the side receiving the radiant heat becomes an ascending airflow, and the airflow fins DD in the one-way wall are automatically opened by the slight wind pressure of the ascending airflow. The warm air flowing from the air passage B ₁ via the bidirectional opening E merges with the warm air flowing through the air passage B ₂ in the upper part of the internal structure space C, and the air passage on the side not receiving radiation to reach B _2. But wind pressure on the fin of the one-way wall airflow fins DD acts from the opposite direction to close, warm air flow to the air passage B ₁ represents not penetrate. Therefore, the air passage B ₁
Because the air remains stationary, there is no condensation inside the outer wall and it has an insulating effect, the air flow circulates under the floor and reduces the heating load.

In this case, it is assumed that the airflow fins behind the hut are always closed by the action of the magnet.

It should be noted that the unidirectional wall airflow fins D and DD are merely reversed in installation.

The two-way opening E does not have the fin body D.

Here, since the air passage is doubled,
The air circulation efficiency is good.

FIG. 3 is a perspective view showing the configuration of the air fins in the wall. Since the under-floor air fins, the in-wall air fins, and the under-air air fins have a structure that covers the opening from one direction, there is no side space (a portion r in FIG. 9) unlike the conventional fins.
Hermeticity is perfect. The contour of the wall in the airflow fins a circular cylinder <br/> form, in its mounting, can simply drilling a hole with a drill, labor for machining the mounting holes on the rectangular can save labor.

Further, the air fins in the wall are characterized in that they can be installed very easily by merely applying an adhesive to the thickness of the heat insulating material itself and inserting the adhesive material into the fins.

Furthermore, since the outer shape is accommodated in the heat insulating material, it is easy to carry. In particular, it can be incorporated into a heat insulating material at a factory and transported to the site, leading to a reduction in the number of construction steps.

The airflow fins in the wall are balanced so that the fins cover the openings and close even in a substantially horizontal position, so that malfunction does not occur even on a roof having a slope of 45 ° or less.

FIG. 7 is a perspective view showing the structure of the air fins under the floor and the air fins behind the hut. Both are the same airflow fin and differ only in the mounting direction. That is the airflow flows from outdoors in the under-floor air flow fin, towards the hut back airflow fin is mounted so that the air flow begins to flow from the indoor.

Since the fin seat is a molded product having a cavity inside, the heat insulating effect is large.

In FIG. 1, the magnet of the underfloor airflow fin F is released, and the wind pressure of the cool air on the side not receiving the radiation pushes the underfloor airflow fin F to introduce cool air under the floor. The underfloor airflow fins F on the side receiving the radiation are automatically closed by receiving the wind pressure of the introduced cool air. The cool air introduced under the floor rises as an ascending airflow between the air passage B ₁ formed by the outer wall and the heat insulating wall I and the air passage B ₂ between the heat insulating wall I and the wall A forming the internal structure space C, through also an air passage B ₁ under the roof leading to the attic. Here, the magnet of the airflow fins G behind the hut is released, and the airflow is automatically released by the wind pressure of the rising airflow, and the rising airflow naturally convects as indicated by the arrow to reduce the cooling load.

[0047]

The effects of the present invention are as follows.

At the time of warmth and heat, the magnets of the underfloor air fins F are opened, and the underfloor air fins F on the side not receiving radiation due to the slight wind pressure from the cool air side are opened, and the underfloor airflow fins on the side receiving the radiation by guiding cool air under the floor. Since F receives a back wind pressure, it is automatically closed and does not let cool air escape from under the floor.

The cold air flowing under the floor receives the radiation,
The warm air that has passed through the double air passages B ₁ and B ₂ on both sides on the opposite side to become an ascending airflow, and that has passed through the air passage B ₁ under the roof,
The air is released outside through the open airflow fins G behind the hut. In this way, the cool air naturally convects to reduce the cooling load.

In cold weather, the underfloor airflow fins F are both closed by the action of the magnet on the side receiving the radiant heat and on the opposite side.

The air in the air passage B ₁ on the side receiving the radiant heat becomes an ascending airflow, and the one-way airflow fins DD are automatically opened by the slight wind pressure of the ascending airflow. The warm air flowing from the air passage B ₁ via the bidirectional opening E merges with the warm air flowing through the air passage B ₂ in the upper part of the internal structure space C, and the air passage on the side not receiving radiation to reach B _2. But wind pressure on the fin of the one-way wall airflow fins DD acts from the opposite direction to close, warm air flow to the air passage B ₁ represents not penetrate. Therefore, the air passage B ₁
Because the air remains stationary, there is no condensation inside the outer wall, and the airflow circulates under the floor, reducing the heating load.

In this case, the airflow fins behind the cabin are always closed by the action of the magnet.

The air fins under the floor and the air fins behind the hut are the same, and only the mounting direction of the fins is different. The common use of the fins enables compatibility, facilitates product type management, and leads to cost reduction. Further, the fin seat of the fin is a molded product having a cavity inside, so that the heat insulating effect is large.

The airflow fins under the floor, the airflow fins inside the wall, and the airflow fins behind the shed have a structure that covers the opening from one direction.
There are no side gaps as in conventional fins, and the airtightness is perfect. Further, the outer shape of the airflow fins inside the wall is circular, and it is only necessary to drill a hole to attach the airflow fin, and labor for machining the rectangular mounting hole can be saved.

The airflow fins in the wall are characterized in that they can be installed very simply by applying an adhesive to the thickness of the heat insulating material itself and inserting the adhesive material into the heat insulating material itself, so that it can be extremely easily installed.

Further, since the outer shape is accommodated in the heat insulating material, it can be easily incorporated into a heat insulating material at a factory and transported to the site, thereby reducing the number of construction steps.

The airflow fins in the wall are balanced so that the fin body covers and closes the opening even in a substantially horizontal position, so that there is no malfunction even on a roof having a slope of 45 ° or less.
