Abstract

PURPOSE: To provide an air damper in a dwelling of air cycle structure which is sufficient in air volume, inexpensive and easy in fitting by suspending a small piece of a heat insulating plate in an oscillating manner from a lower end part of the heat insulation plate. CONSTITUTION: In an air damper in a dwelling of air cycle structure, a small piece 5 of a heat insulation plate is suspended in an oscillating manner from a lower end part of a heat insulating plate 1. When the weak wind blows, the small piece 5 of the heat insulation plate is pressed to allow the air to pass. When the wind blows in the opposite direction, the small piece can be held in the suspended position.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application> The present invention relates to a damper for air passages in a house having an air cycle structure.

<Conventional technology> As shown in Figure 3, a house with an air cycle structure has an attic ventilation opening (2) with a shutter and an underfloor ventilation opening (3) in the attic and under the floor, and also has an attic ventilation opening (2) with a shutter and an underfloor ventilation opening (3) in the attic and under the floor. An air passage is created by opening a space between the two, and an insulating plate (1) is provided approximately in the middle of the air passage to make the air passage double, and an air damper (4) is provided at the lower end of the insulating plate (1). The damper opens when air flows from the indoor side to the outdoor side, and closes when air flows from the outdoor side to the indoor side.

Therefore, the air around the house flows in response to changes in the temperature of the outside air, increasing the indoor heating and cooling effect.

To explain in more detail the flow of air using arrows, Figure 3 (a) shows how it is used in summer, with the attic ventilation opening (2) and the underfloor ventilation opening (3). Let's open it together.

By opening the attic ventilation opening (2), air that has become hot due to sunlight and accumulated in the attic, or air that has become hot inside the south wall, will rise and exit through the attic ventilation opening (2). go.

Instead, cold air from the north side of the house and under the floor enters through the ventilation openings (3) under the floor, opens the air damper (4) and rises through the Saint's room, lowering the temperature of the walls and ceiling, so the room does not get too hot even in summer. .

Figure 3 (b) shows the usage situation during the daytime in winter. By closing both the attic ventilation opening (2) and the underfloor ventilation opening (3), on warm winter days, the south side The air behind the wall is warmed and rises, descends through the blue space on the north side of the attic, passes under the floor, and returns to the blue space on the south side.
warms up and rises. This allows warm air to circulate around the house, making the entire room warmer.

Next, Figure 3 (A) shows the usage situation at night in winter. At this time, the air flow stops, so the air damper (4) is closed on both the south and north sides and is used during the day. Warm air stagnates in the blue space, and the cold outside air is blocked by a double layer of warm air, so the room stays warm for as long as it takes.

This air damper (4) has conventionally been used by fitting a device as shown in No. 21ffl into a heat insulating plate (1).

The structure of the device is that a very light board (6) is suspended by a hinge that moves lightly, so when air flows from the indoor side to the outdoor side, the light board (6) is pushed away by the wind, and the air will now pass. Conversely, when air flows from the outdoor side to the indoor side, the light plate (6) remains lowered, preventing air from passing through.

<Problem to be solved by the invention> For this reason, if the amount of air passing through the air damper is insufficient, it is necessary to attach several of these devices, but since they are installed between pillars, there are restrictions and it is not necessary to add more. The air volume was insufficient.

In addition, the air damper equipment is expensive, and it takes time and effort to install it.

Therefore, the present invention provides an air damper that can provide a sufficient amount of air, is inexpensive, and can be easily installed.

Measures to Solve Problems> For this reason, a small piece of the same insulation board was suspended from the lower end of the insulation board using a hinge that moved lightly.

For this reason, when a weak wind blows, small pieces of the board are pushed away,
It allows air to pass through, but when the wind blows in the opposite direction, a stopper is installed at the hanging position to act as a shutter.

<Example> Fig. 1 shows an example of the air damper according to the present invention, in which a small piece (5 pieces) of the same hard foam urethane board is attached to the lower end of a heat insulating board (1) using a hard foam urethane board.
), a film (7) made of synthetic 41 resin is sandwiched between each plate, fixed with adhesive, and hung.

For this reason, when a weak wind blows from the indoor side, the damper easily opens and air passes through, but when the wind blows from the outdoor side, the stopper acts as a shutter and blocks the movement of air.

Since the small piece (5) of the hard foamed urethane board can be suspended over the entire width of the lower end of the insulation board (1), a sufficient amount of air can pass through it.

Furthermore, when this heat insulating material plate (1) is installed, an air damper is also installed at the same time, so there is no need to separately install an air damper, making the construction extremely simple.

<Effects of the Invention> Conventionally, in a house with an air cycle structure, an air damper device was attached to a heat insulating board placed in the middle of the green space, but according to the present invention, an air damper device is attached to the lower end of the insulating board. Since it is only necessary to attach small pieces of suspended insulation board, construction time is shortened and a large amount of air can be sent at a low cost.
