Abstract

PURPOSE:To enable a building ventilation to be adapted for four seasons in Japan by a method wherein slider ventilation port provided with an adjusting mechanism is arranged at an air chamber inside the door. CONSTITUTION:During summer season, since the slider ventilation port 2 is opened, the wind is passed through the ventilation port 5 in the ventilation door at the upstream side, air chamber 4, aeration port 12, aeration ports 13, 14 and 15 of the slider ventilation port 2 and then flows into the space 26 of a ceiling room. In turn, at the downstream side, a pulling force is applied under a negative pressure, the hot air in the ceiling room space 26 is passed through the aeration ports 15, 14, 13 of the slider ventilation port 2, air chamber 4 and aeration port 5 of a ventilation door 1 and then discharged out of the house. During winter season, if a switch is changed over, a low speed motor is rotated, an arm 21 is pulled, a fulcrum point fixed to the plate 17 is simultaneously slid to close the aeration ports 13 and 15. In this way, the eaves door is ventilated and closed, thereby a comfortable dwelling circumstance can be created both in summer and winter.

Description

[Detailed description of the invention] The present invention relates to attic ventilation for houses and the like.

Conventionally, for residential attic ventilation, a vent was installed high in the attic space for a gabled building, and a vent was installed in the eaves for a hipped building.

These vents are installed in a way that makes it unclear whether they are intended for summer or winter, and a phenomenon has emerged in which it is cold in winter and hot in summer.

In addition, in Japanese-style decorative eaves, the area above the girder called a mento is usually blocked off with a board to prevent ventilation, which results in lack of ventilation and hot summers.

In some cases, a part of the mendo door was removed to create a ventilation opening, but if the ventilation opening was sized for the summer, it would be cold in the winter, making it difficult to create a ventilation opening.

The length of the door is equal to the length of the girder, and if you install a ventilation hole corresponding to this length, you can guarantee coolness in summer, and it has been proven in old private houses that you can live without an air conditioner. However, it is natural that winter can be a battle against unbearable cold.

Therefore, the present invention aims to accommodate Japan's four seasons by opening the ventilation openings in the door in the summer and closing them in the winter.

Hereinafter, the present invention will be described in detail with reference to the drawings.

Roof tarki (6) is placed on girder (7) 1) Roof tarki (6)
) and the space for the height of the girder (7) and the roof board (9).
It has a letter-shaped cross section with a ventilation hole (5) on the long side and a nail hole (5) on the short side.
Place the ventilation door (1) with the nail hole (8) on the top of the girder (7).
), and inside it, attach an air chamber (
4) and the vent α2 created between the auxiliary material αQaD.
Between the plate with vent αJ (161) and the plate with vent 09 (181), the plate with vent αJ (
17) Attach a sliding ventilation opening (2) that can be slid by the opening/closing machine (3).

Let's take a look at how a ventilation hole installed like this works.

In summer, the slide ventilation opening (2) is open as shown in Figures 9 and 10. An example thereof will be explained with reference to FIG.

If the wind is coming from the right direction in the drawing, the wind will flow through the ventilation opening (5) of the ventilation door (1) on the windward side, the air chamber (4), and the ventilation hole αz.
It flows into the attic space (A) through the ventilation hole (13 (141Q9) of the 1 slide ventilation opening (2).On the other hand, on the leeward side, a pulling force is applied due to negative pressure, and the hot air in the attic space (C) is the slide ventilation opening (2).
13), Vent αz1 Air chamber (4), Ventilation side door (1) Vent (5) is released to the outside, hot air is released through this series of air flows, and the building is cooled by outside air. It is.

Also, when there is no wind, outside air enters the under-floor ventilation opening (5) due to the temperature difference between the outside air and the inside of the building and drains into the under-floor space C? A ventilation door (1) rises from the wall cavity that connects S and the attic space (26).
It releases hot air.

In the winter, if you change the electric switch at hand, the inside of the deceleration motor will rotate, and the rotation axis a will rotate, and the 9 movement fulcrum (2G will rotate around the rotation axis α9, rotate 180 degrees, and turn the rotary switch (c) is limit switch t24)
When touched, the electricity is cut off and the deceleration motor (25) stops.

With this series of movements, the arm (2I) is pulled, and the fulcrum (21) fixed to the plate αη also slides at the same time to close the vent αJα9. The shape is shown in Figure 11.12. Of course, the underfloor ventilation opening (3) is also closed.

In this way, by closing the ventilation holes in buildings and cutting them off from outside air, it is possible to maintain warmth in the winter.

As described above, by ventilating and shutting off the side door at the needle base, needle base ventilation can save energy and create a comfortable living environment in both summer and winter.
