Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air shutter for controlling the transfer of air between the underfloor space and the attic space of a house.

[Conventional technology]

Conventionally, air was transferred by installing a ventilation fan in each duct tailored to the purpose.

For this reason, a duct circuit was required for each. or,
The duct connected to the outside air had no closing mechanism, allowing air to freely flow in and out.

Problems such as this were poor thermal efficiency and the cost and space of constructing double ducts.

[Problem that the invention seeks to solve]

Therefore, in order to eliminate the drawbacks of the prior art, the present invention aims to reduce costs by using a shutter to open and close a duct that opens to the outside, and a switching shutter when a double duct is required.

[Means to solve the problem]

The present invention will be explained below based on the drawings.

Then, the cam (c) and the fulcrum connected to the rotating shaft (movement) rotate and push the fulcrum αυ away from the opening/closing machine eel of the arm Q3.
As shown in Figure 11, the limit switch (C) arm (
) is released, the contact OD of the limit switch (A) switches to the contact B, the deceleration motor (To) stops, the slide shutter (9) moves to the position shown by the dotted line, and the vent (
1) , (31, (23, (4)) are closed.

The operation of the switch (19) in cases 2 and 3 is also similar.

〔Example〕

Hereinafter, the present invention will be described in detail based on the drawings.

This will be explained starting from claim 1.

Intermediate ventilation fans (44, (c)) on both sides of the air shutter slope
There is a field board (41J) connected to the insulation duct.
A slit pipe Gη with a partition CHI in the center of the cylinder and slits on both sides is the insulation duct 0 between the tiled roof he and the
Connected to 2.

During the daytime in summer, vents (1), (3), (2)
, (4) is opened and drives the intermediate ventilation fan (44J) to release the hot air from the attic space (43) through the slit of the slit vibro η into the gap in the tiled roof, cooling the roof and cooling the attic space (43). It throws away the heat.

Also, at night, the intermediate ventilation fan (44) is stopped and the intermediate ventilation fan (c) is driven to cause air to flow in the opposite direction of the arrow.
The cold air from the cold tiled roof θQ and outside air are guided into the attic space @j to cool the building.

In winter, the slide shutter (9) is operated by the opening/closing machine (11).

Next, the second claim will be explained.

In an insulated building, the underfloor ventilation and the attic ventilation can be opened and closed, and the underfloor space ■ and the attic space (43 odaku) are electrically conductive (4η) and an air shutter is installed in the underfloor space.
duct) (47) is connected to the vent I, and the underfloor space is 0.
6) Connect the duct θυ close to the ground.

The ventilation port α3 is connected to the outside air by a duct 6Q, the duct 153 is connected to the ventilation port a, and the intermediate ventilation fan (4a) is attached to the duct ei2.On the other hand, the duct G
An intermediate ventilation fan is installed in the attic space (43) of 1η, and the building has a structure in which the wall space is connected to the underfloor space (2) and the attic space (43).

Let's start with the case of summer.

In summer, the underfloor ventilation and attic ventilation are open. A check valve is installed in the underfloor ventilation hole. As shown in Figure 27, the air shutters (2) and (4) are open.

A perspective view is shown in FIG. 22.

Intermediate ventilation fan (if the 4-way fan is driven, the outside air will flow through the duct)
It passes through the vents (2) and (4) and enters the underfloor space (a), pressing against the reverse valve 64) of the underfloor ventilation, and the pressure rises through the wall cavity 6■ and flows into the attic space 03. The hot air is then released outside through the attic ventilation.

In winter, the underfloor ventilation opening and the attic ventilation opening are closed and the air shutter ■ is switched by the opening/closing machine Q9 as shown in Fig. 26. The perspective view is a third view.

When the intermediate ventilation fan (49) is driven, the cold air in the underfloor space (c) is transferred from the duct 6υ, (4η) to the attic space (43), and is mixed with the warm air in the attic space (4'5) to eliminate the cold air. The mixed air then falls down the wall cavity and returns to the underfloor space.

In this way, the building is heated evenly.

Next, Claim 3 will be explained.

In an insulated building, the underfloor ventilation and the attic ventilation are openable and conductive through the underfloor cavity and the attic space (43t duct) 661. An intermediate ventilation fan 6 is installed between the duct)elfl and the air shutter @.
51 and the vent αa is connected to the attic space (duct 57).
4 Above the power, the ventilation hole (19 is on the duct side and the attic space (
43 and opens downward. The building has a wall cavity (to) that connects the underfloor space (4Ei) and the attic space (c).

Let's start with the case of summer.

The underfloor ventilation opening and the attic ventilation opening are open, and the air shutter has ventilation openings (2) and (4) open as shown in FIG.

If you drive the intermediate ventilation fan @, the cold air from the underfloor space (c) will pass through the duct mark to the vent (2) near the air shutter Q.

(4) Cold air is discharged from the duct 6 to the ceiling, some of the air falls down the wall cavity ci3) and returns to the underfloor space, and some of the air pushes out the hot air from the attic space 03 through the shed ventilation opening. This amount of outside air is sucked in from the underfloor ventilation holes. This is how the building is cooled.

In winter, close the underfloor ventilation and attic ventilation, and use the air shutter as shown in Figure 16 (1).

(3) is open.

When the intermediate ventilation fan fg8j is driven, the cold air in the underfloor space (c) passes through the duct ■all-way vents (1), (3)e and is discharged from the duct 6η to the top of the attic space (43) where it mixes with warm air and becomes cold air. is removed and returns down the wall cavity (g) to the underfloor space (c), which has become a negative pressure.In this way, the warm air in the upper part is used to provide space heating.

〔Effect of the invention〕

As explained above, the present invention is an air shutter that contributes to cost reduction and energy saving by cutting off or opening the air flow inside and outside, and by not doubling the duct.
