Abstract

PURPOSE:To open a garret exhaust port during summer and close it during winter and to use it for exhaust purpose exclusively during summer and exhaust heat with the aid of a ventilation fan during a windless time, by a method wherein a partition having a vent port is installed to the garret exhaust port, a check valve and a damper positioned opposite to the check valve are mounted to the partition, and the damper is opened and closed with the aid of a motor-operated opening and closing device. CONSTITUTION:During summer, a damper 4 of a garret exhaust port 1 is opened and a damper 25 of an underfloor ventilating port 20 is also opened. During windy weather, a check valve 6 closes a vent port 3 at the garret exhaust port 1 on the windward to stop entrance of wind. Meanwhile, on the leeward, a check valve 6 is opened by a negative pressure to pull off a heated air in a garret space 19. In an underfloor space 22, the open air forcibly opens a check valve 21 to enter from the windward, and on the leeward, the air is stopped by the check valve 21, and a wind pressure pushes up a heated air from a wall cavity 23 and a partition cavity 24 into the garret space 19 to cool a building. During winter season, if the damper 4 and a damper 25 of an underfloor ventilation port 20 are closed, the air inside and outside a building is prevented from replacement by each other, resulting in ensurance of warm and comfortable living.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to attic ventilation of houses. [Prior Art] In recent years, many houses have been constructed due to the housing boom. However, many of these houses were built before energy conservation became an issue, and they are unsuitable for today's energy conservation era.

In particular, many attic vents are simple, fixed-open types, which have the disadvantage of not providing enough exhaust power in the summer, and in the winter, heat being easily dissipated due to the difference in temperature between the inside and outside.

When it's windy and rainy, rain tends to come in with the wind, causing rain leaks, and it can also become a trap for noise and debris.

Another problem is that the building becomes hot during the day when there is no wind because heat is not exhausted during the windless period in the summer.

[Problem that the invention seeks to solve]

Therefore, in order to eliminate the drawbacks of the prior art, the present invention provides a function for opening the attic ventilation opening in the summer and closing it in the winter, and furthermore, in the summer, it is used for exhaust only, and when there is no wind, a ventilation fan is used to exhaust heat. The purpose is to

[Means to solve the problem]

Hereinafter, this invention will be explained based on the drawings.

The configuration will be explained with reference to Figure 3.4.

Partition board (2) with vent (3) in attic exhaust outlet (1)
There is a check valve (6) hanging on the hinge (7) on the partition plate (2) and a damper (4) hanging on the hinge (8) on the opposite side. Electric opening/closing [(5
) Attic exhaust vent that opens and closes.

[For production]

Next, the operation will be explained with reference to Fig. 3.4.11.21.

The electric switchgear [(5) has a pressure switch (15) on the damper (4) side and a limit switch (16) on the opposite side.
Damper (4) and electric switchgear (5) are wired (17)
It is linked with.

The electric opening/closing fit (5) is operated by a forward/reverse motor (14).

In winter, the damper (4) hangs down and is pressed against the partition plate (2) by the pressure switch (15) K, as shown in FIG. 3, and is in a closed state.

In this case, the air inside the building cannot be moved by pushing or pulling the outside air.
) or the check valve (6) is tensioned to ensure airtightness.

In fact, the stronger the wind, the higher the airtightness, and the more effective it is at keeping the air from moving.

With commonly used opening/closing devices, either pushing or pulling breaks the airtight and moves air, cooling the building.

Next, in summer, when the switch contacts (18) and (28) are connected, the contacts (28) and (29) are energized, the forward/reverse motor (14) rotates, and the damper (4) is connected to the wire (17). The limit switch (16) is then pulled up and opened by the attic exhaust outlet (1) K contact point (29).
) is cut and the forward/reverse motor (14) stops.

As shown in Figure 4.11, if there is wind from the right direction in the drawing, the mine stop valve (6) will close the vent (3) on the windward side, and the check valve (6) on the leeward side will close due to the wind pressure. It opens to exhaust hot air from the attic space (19).

In other words, it is used exclusively for exhaust air without letting outside air in. If it is closed in winter, the switch should be connected to contacts (18) and (26).
), the contact (27) of the pressure switch is energized, the forward/reverse motor (14) rotates in reverse, and presses the damper (4) against the partition plate (2), and the pressure causes the contact (27) of the pressure switch (15) to close. ) is cut, the forward/reverse motor (14) is stopped, and the vent (3) is closed.

〔Example〕

The present invention will be described in detail below based on the drawings.0 An attic exhaust port (1) is installed in the upper part of the attic space (19), and a damper (25) and a check valve (
Provide an underfloor ventilation opening (20) with an underfloor space (21).
2) and the attic space (19) are electrically connected through a wall cavity (23) and a partition cavity (24).

Let's take a look at the function of the attic exhaust vent configured in this way.

The summer case will be explained with reference to FIG.

The damper (4) of the attic exhaust port (1) is opened, and the damper (25) of the underfloor ventilation port (20) is also opened.

Now, if there is wind from the right direction in the drawing, the check valve (6) closes the vent (3) at the attic exhaust port (1) on the windward side, and no wind enters.On the other hand, on the leeward side, The negative pressure causes the check valve (6) to open and draw out the hot air from the shed S9rLtJ (19).

In the underfloor space (22), check valve (21) is installed from windward.
) is pushed aside and outside air enters, and on the leeward side, the check valve (21)
The air is stopped by the wall and the wind pressure is ff'iJ (23
), the rising hot air is pushed upward from the partition cavity (24) into the attic space (19), thereby cooling the building.

In winter, the damper (4) is closed as described in the operation section, and the underfloor ventilation opening (20) also closes the damper (25). (See Figure 2) If the damper is closed in this way, the air inside and outside will not be exchanged, and you will stay warm in winter.

Next, the second claim will be explained.

Connect the box (9) to the attic exhaust port (1), and insert the slit (
The box bodies (9) are connected as a pair through a slit pipe (10) (11).

The summer case will be explained with reference to Figures 12, 15, and 16.

The hot air that collects in the upper part of the attic space (19) is selectively collected by the slit pipe (10) (11) and exhausted by the force of the wind. It also has a large amount of heat output and can make buildings much cooler.

Other functions in the case of summer and in case of winter are the same as those in claim 1.

Next, Claim 3 will be explained.

An intermediate ventilation fan (12) is provided on one of the slit pipes (10), and a backflow valve (13) is attached to the end of the slit pipe (10) of the box body (9) on the exhaust side.

This will be explained with reference to FIG.

When the temperature inside the building reaches high temperatures during the summer daytime with no wind, the intermediate ventilation fan (12) can be turned on manually or automatically using a thermoswitch.
The end of 10) is closed, and the hot air is sucked from 11) into the intermediate ventilation fan (12), pushes aside the check valve (6), and is discharged to the outside.

On the other hand, in the underfloor space (22), outside air flows into the underfloor space (22) from each underfloor ventilation opening (20) by displacing the check valve (21) and is pulled up into the attic space (19), keeping the building cool. It is.

The case where there is wind and the case of winter are the same as in claim 2.

〔Effect of the invention〕

As explained above, the present invention is an attic exhaust vent that can keep the attic cool in summer through natural wind or ventilation by a ventilation fan, and keep warm in winter by blocking outside air and save energy for heating and cooling.
