本発明は、換気装置に関し、詳しくは例えば床下などの
換気を自動的に行う技術に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilation system, and more particularly to a technique for automatically ventilating areas such as under the floor.
従来、例えば北国（東北、北海道ルカ）において、床下
に雪が舞い込み、これらが堆積し、凍結する場合には、
布基砿部分を傷めたり、床下温度を著しく低下させるこ
とになるので、床下換気のために設けたフコラリを冬期
には閉塞するものであった。ところが閉塞するのを忘れ
ることがらシ、上記の問題を招きやすいものであった。Traditionally, for example, in northern countries (Tohoku, Hokkaido), when snow falls under the floor, accumulates, and freezes,
The fukorari installed for underfloor ventilation was to be closed off during the winter, as this would damage the fabric part and significantly lower the temperature under the floor. However, if one forgets to close the blockage, the above problems tend to occur.
このような問題を解消するのに、種々の強制開閉駆動装
置を設けることも考え゛られるが、装置が犬がかりとな
シ、それでいて自動開閉できないという問題があった。In order to solve this problem, it has been considered to provide various forced opening/closing drive devices, but there is a problem in that the devices are dog-locked and cannot be opened/closed automatically.
本発明はこのよりな画題に鑑みてなされたものであり、
その目的とするところは、簡単な装置で換気口を自動開
閉するとさができる換気装置を提供することにある。The present invention was made in view of this more specific theme,
The purpose is to provide a ventilation system in which ventilation openings can be automatically opened and closed using a simple device.

ことができたのである。That is, in the present invention, the positions of the holes (2) of the two perforated plates (+4-114-) are shifted from each other, and the two perforated plates (4) (4-1) are ventilated through the ventilation opening (3). They are provided facing each other so that the openings (3) can be closed, and one of the perforated plates (4) is fixed, and the other perforated plate (4) can freely come into contact with and separate from the fixed perforated plate (5). This relates to a ventilation device characterized in that a movable perforated plate (6) is supported by a displacement body (7) made of a shape memory alloy that can be largely and reversibly changed by temperature changes. With this configuration, it was possible to automatically open and close the ventilation openings with a simple device.

以上である。(~ is a ventilation system, which is used for under-floor ventilation of houses, but it can also be used in other places.Ventilation openings (3) are formed in the fabric foundation (8) that separates indoors and outdoors. , ventilation opening (3
) is fitted with a lattice-like partition (9) like a slatted grid to prevent small animals and garbage from entering the indoor side. On the indoor side of the ventilation opening (3), two perforated plates +4)f4+ as shown in Fig. 2 are provided. The holes (2) of these perforated plates +4141 are shifted from each other at 8
When two sheets are stacked, each hole (2)...
This makes it possible to block all of them. One of the perforated plates (4) is fixed between the holding parts (+o and 5), and the perforated plate (4) is placed on the outdoor side of the fixed perforated plate (5). ), and the moving perforated plate (6) and the fixed perforated plate (5
) is provided with a plate-shaped displacement body (7) made of a shape memory alloy that can greatly reversibly change the opening angle in a hinge-like manner depending on temperature changes. Variable body (7)
is a body that displaces greatly due to temperature changes, and as a displacement body (7) that displaces largely and reversibly due to temperature changes, for example, 0
When the temperature drops beyond a specific (transformation) temperature such as °0, martesisite transformation occurs and the material deforms significantly into a specific shape, and when the temperature exceeds a specific temperature such as 0υ mentioned above, it reversibly deforms to its original shape. There is a shape memory alloy (commonly known as Nitinol) that does this, but other materials may also be used. Shape memory alloys are alloys of nickel, titanium, etc., and can be produced over a wide range from -278°C to 100'O by changing the ratio of nickel to titanium and adding small amounts of other elements. Its transformation temperature can be controlled. Moreover, when it takes on a specific shape through transformation, the force exerted is approximately 200 times or more compared to the force due to expansion and contraction of a bimetallic transponder of the same size.

When the temperature rises above about θ'C outside of winter, the displacement body (7) deforms to its original shape, and moves the movable perforated plate (6) away from the fixed perforated plate (5). , the ventilation opening (3) is automatically opened. and,
In such an open state, the positions of the holes (2)... of the perforated plate [4) f4) are misaligned, so that dirt passes through the holes (2) (21) of the two perforated plates +4++4+ to the indoor side. In addition, as shown in Fig. 8, when the movable perforated plate (6) is installed outdoors, the movable perforated plate (6) is blocked by external force such as wind. Even if something happens, there is no need to open it. Fig. 4 shows another embodiment in which a movable perforated plate (6) is disposed on the indoor side of a fixed perforated plate (6). Figure 5 shows yet another embodiment, in which a slatted partition (9) is attached to an identified perforated plate (0,...) and a movable perforated plate (6) is arranged on the indoor side. 7 shows still another example.

While fully fixed, the other perforated plate is placed in contact with and separated from the fixed perforated plate, and the movable perforated plate is supported by a displacement body made of a shape memory alloy that can be reversibly changed by temperature changes. Therefore, the displacement body is largely reversibly displaced due to temperature changes in summer and winter, and the movable perforated plate is brought close to the fixed perforated plate to close the ventilation opening, and the movable perforated plate is moved away from the fixed perforated plate. There is an advantage that the ventilation port can be opened and closed automatically using a simple device. In addition, since two multi-plate plates with the holes shifted in position are used, the positions of the holes are shifted not only when the two perforated plates are in contact with each other, but also when they are separated from each other. This has the advantage of preventing dust from blowing into the interior.
