Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、住宅等の小屋裏を換気する装置に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a device for ventilating an attic such as a house.
住宅建材の進歩により室内の高気密化が一般化し、それ
に伴なって生活居住環境を悪くする結露、カビ、冬季の
酸欠等の問題が生じるが、それらを防ぐ為に季節に応じ
て最適に呼吸する家屋が良いとされている。Due to the advancement of housing construction materials, airtightness in the room is becoming common, which causes problems such as dew condensation that deteriorates the living and living environment, mold, and oxygen deficiency in winter, but it is best suited according to the season to prevent them. A breathing house is said to be good.
例えば、実開昭59−189020号公報に示すように、小屋裏
の軒先側と棟木側とに換気装置を設け、外気を小屋裏に
とり入れたり、小屋裏の空気を外部に排出したりしてい

そして、前記換気装置は第３図、第４図に示すように構
成してある。The ventilation device is constructed as shown in FIGS. 3 and 4.
つまり、方形枠状の本体１に上下方向に向う通気口２を
形成し、本体１の上部にダンパー３を上下回動自在に設
けると共に、本体１内に設けたモータ４の出力側を第１
リンク５、第２リンク６を介してダンパー３に連結し、
モータ４を正転するとダンパー３が上下に回動して通気
口２を開閉するように構成してある。That is, the ventilation hole 2 that is oriented in the vertical direction is formed in the rectangular frame-shaped main body 1, the damper 3 is provided on the upper portion of the main body 1 so as to be vertically rotatable, and the output side of the motor 4 provided in the main body 1 is the first side.
Connected to the damper 3 via the link 5 and the second link 6,
When the motor 4 is normally rotated, the damper 3 is vertically rotated to open and close the vent hole 2.
かかる換気装置であると、ダンパー３の一端部が本体１
に連結され、ダンパー３の中間部に第２リンク６が連結
されてダンパー３を第１・第２リンク5,6により押し上

角度、つまり開き角度αが第１・第２リンク5,6の長さ
によって決定され、しかも第１・第２リンク5,6はダン
パー３を閉じた時に本体１の高さ内に納める必要があ
る。According to such a ventilation device, one end of the damper 3 has the main body 1
The second link 6 is connected to the middle part of the damper 3 to push up the damper 3 by the first and second links 5 and 6 to open the vent hole 2, so that the rotation angle of the damper 3 is increased. That is, the opening angle α is determined by the lengths of the first and second links 5 and 6, and moreover, the first and second links 5 and 6 must be housed within the height of the main body 1 when the damper 3 is closed.
このため、第１・第２リンク5,6を長くして前記ダンパ
ー３の開き角度αを大きくすると本体１の高さ、つまり
空気流通方向の寸法が大きくなってしまうし、本体１の
空気流通方向の寸法を小さくするために第１・第２リン
ク5,6を短かくするとダンパー３の開き角度が小さく本
体１の通気口２を流通する空気の流通抵抗がダンパー３
によって大きくなり、スムーズに空気を流通できないの
で効率良く換気できない。Therefore, if the opening angle α of the damper 3 is increased by lengthening the first and second links 5 and 6, the height of the main body 1, that is, the dimension in the air flow direction, becomes large, and the air flow of the main body 1 is increased. If the first and second links 5 and 6 are shortened in order to reduce the dimension in the direction, the opening angle of the damper 3 is small and the flow resistance of the air flowing through the vent hole 2 of the main body 1 is reduced.
As a result, the air becomes larger and the air cannot flow smoothly, so efficient ventilation cannot be achieved.
そこで、本考案は、前述の課題を解決できるようにした
換気装置を提供することを目的とする。Then, this invention aims at providing the ventilation device which was able to solve the above-mentioned subject.

この時、ピン51は前述の位置であるからクランクアーム
50とリンク52は一直線状とならずに所定角度θを成すの
で、クランクアーム50が矢印方向に若干回転するとダン
パー30を更に閉じる方向に回動するので、モータ46の停
止位置が若干ずれてもダンパー30で通気口59を確実に閉
じることができる。At this time, since the pin 51 is in the position described above, the crank arm
Since the 50 and the link 52 do not form a straight line and form a predetermined angle θ, when the crank arm 50 slightly rotates in the direction of the arrow, the damper 30 further rotates in the direction in which the damper 30 is further closed. The damper 30 can surely close the vent hole 59.
つまり、クランクアーム50をピン51が直線X1上となる位
置で停止させるようにすると、モータ46の停止位置が若
干ずれるとピン51が直線X1を越えてダンパー30を開き側
に回動するから通気口59を確実に閉じることができな
い。That is, the crank arm 50 pin 51 when be stopped at a position where the upper straight line X 1, pin 51 when the stop position is slightly shifted in the motor 46 is rotated in the opening direction of the damper 30 beyond the straight line X 1 Cannot securely close the vent hole 59.
これと同時に、ダンパー30は緩衝材18に当接するので騒
音を発生したりすることがない。At the same time, since the damper 30 is in contact with the cushioning material 18, noise is not generated.
前述の状態よりモータ46を回転して出力軸47を矢印方向
に回転するとクランクアーム50とカム49が矢印方向に回
転してリンク52を下方に移動するのでダンパー30はヒン
ジ38を中心として上方に回動し、クランクアーム50とリ
ンク52が第１図仮想線で示すように一直線状となるダン
パー30が略水平姿勢となって通気口59を開放し、ダンパ
ー30の開放角度を大きくできる。When the motor 46 is rotated in the above-described state to rotate the output shaft 47 in the arrow direction, the crank arm 50 and the cam 49 rotate in the arrow direction and move the link 52 downward, so that the damper 30 moves upward about the hinge 38. When the damper 30 is rotated, the crank arm 50 and the link 52 are in a straight line shape as shown by the phantom line in FIG. 1, and the damper 30 is brought into a substantially horizontal posture to open the vent hole 59 and increase the opening angle of the damper 30.
この様にダンパー30を略水平姿勢に回動するので、通気
口59を全て開放できて流通する空気の流通抵抗が小さく
なるから空気をスムーズに流通でき、遮蔽板55を押し開
いて小屋裏内の空気を屋外に排出できる。Since the damper 30 is rotated in a substantially horizontal position in this way, the ventilation holes 59 can all be opened and the circulation resistance of the circulating air is reduced, so that the air can be smoothly circulated, and the shielding plate 55 is pushed open to open the inside of the attic. The air can be discharged outdoors.
この時、カム49の低部49bがリミットスイッチ54の可動
片54aと対向してリミットスイッチ54はOFFするので、そ
れによってモータ46を停止させる。At this time, the lower portion 49b of the cam 49 opposes the movable piece 54a of the limit switch 54 and the limit switch 54 is turned off, so that the motor 46 is stopped.
また、屋外より小屋裏内に空気が流れようとすると遮蔽
板55を閉じて取付けフランジ14の一側面に押しつけるか
ら、通気口59を閉じて小屋裏内に空気が屋外より流れ込
むことを防止できる。Further, when air tries to flow into the attic from the outside, the shielding plate 55 is closed and pressed against one side of the mounting flange 14. Therefore, it is possible to close the ventilation port 59 and prevent air from flowing into the attic from the outside.
ダンパー30を開閉するクランクアーム50とリンク52はダ
ンパー30が垂直姿勢の閉じ状態、略水平姿勢の開放状態
においてクランクアーム50が上下方向に向い、かつリン
ク52と略一直線状となるので、クランクアーム50とリン
ク52を長くしても本体10の空気流通方向に突出しない。Since the crank arm 50 and the link 52 that open and close the damper 30 are oriented in the vertical direction when the damper 30 is closed in the vertical posture and opened in the substantially horizontal posture, and the crank arm 50 and the link 52 are substantially in a straight line, Even if 50 and the link 52 are lengthened, they do not project in the air circulation direction of the main body 10.
これによって、クランクアーム50とリンク52を長くして
ダンパー30の開き角度を大きくできるし、本体10の空気
流通方向の寸法を小さくできる。As a result, the crank arm 50 and the link 52 can be lengthened to increase the opening angle of the damper 30, and the dimension of the main body 10 in the air flow direction can be reduced.
したがって、本体10の通気口59を流通する空気の流通抵
抗がダンパー30によって大きくならず、スムーズに空気
を流通できて効率良く換気できるし、建物開口部の室外
側に取付けた場合に本体10が大きく突出しないから違和
感がなく見栄えが良い。Therefore, the flow resistance of the air flowing through the vent hole 59 of the main body 10 is not increased by the damper 30, the air can be smoothly circulated, and the ventilation can be efficiently performed, and the main body 10 can be installed when installed outside the building opening. Since it does not protrude significantly, it does not feel strange and looks good.
