【考案の詳細な説明】
本考案は全く新規な換気扇のシヤツターに関す
る。[Detailed Description of the Invention] The present invention relates to a completely new shutter for a ventilation fan.
換気扇のシヤツターとして、従来、実公昭55−
34509号公報に示すもの、実公昭55−40512号公報
に示すもの等があつた。 Traditionally used as a shutter for ventilation fans,
There were those shown in Japanese Utility Model Publication No. 34509 and Japanese Utility Model Publication No. 40512/1983.
そして、前者はシヤツター外枠内に２枚のシヤ
ツター片を回動可能に枢着するとともに、シヤツ
ター片の室内側に連結片を設けて２枚のシヤツタ
ー片を連動可能とし、連結片を上昇させることに
よりシヤツターを開き、連結片を下降させること
によりシヤツターを閉じ得るようにして成る。 In the former case, two shutter pieces are rotatably attached within the outer frame of the shutter, and a connecting piece is provided on the indoor side of the shutter piece so that the two shutter pieces can be interlocked, and the connecting piece is raised. By this, the shutter can be opened, and by lowering the connecting piece, the shutter can be closed.
従つて、この構成では、シヤツター外枠とシヤ

よつてシヤツター片がばたつき、不愉快な騒音を
発生させることとなる等の欠点がある。 Therefore, with this configuration, a gap is created between the shutter outer frame and the shutter piece, and the room cannot be completely isolated from the outside air when the ventilation fan is not in use, resulting in a decrease in the effectiveness of cooling and heating the room. Not only do
In the case of rain accompanied by wind, there is a risk that rainwater may enter from the above-mentioned gaps, and furthermore, if the wind is strong, the shutter pieces may flap due to the wind pressure, causing unpleasant noise. be.

るようにしている。 In addition, the latter has three shutter pieces rotatably attached within the shutter outer frame, and an L-shaped connecting piece is provided on the indoor side of the shutter piece to enable the three shutter pieces to interlock. A protrusion piece provided at a predetermined position on the lower edge of the connecting piece and a protruding piece that engages when the shutter is closed is provided, and a spring is provided that always biases the connecting piece in the shutter closing direction. As for the connecting part structure, the topmost shutter piece and the connecting piece are connected by a shaft and a round hole so that they can only rotate, and the other shutter pieces and connecting pieces can rotate and slide by using a shaft and a long hole. I'm trying to connect them.
従つて、この構成とすることにより、強風下に
おいてもシヤツター片がばたつき、不愉快な騒音

欠点は解消し得ないのである。 Therefore, by adopting this configuration, it is possible to eliminate the drawback that the shutter pieces flap even under strong winds and generate unpleasant noise, but there is a gap between the shutter outer frame and the shutter pieces, When the ventilation fan is not used, it is not possible to completely isolate the room from the outside air, which not only reduces the efficiency of cooling and heating the room, but also increases the risk of rainwater entering from the gap in the case of rain accompanied by wind. The drawbacks that exist cannot be overcome.
更には、作動部が多く、これらの部分に油滴等
が付着するので故障しやすく、又、シヤツターの
開閉の動作がスムーズでなくなる等の新たな欠点
が生ずる。 Furthermore, since there are many operating parts, oil droplets and the like adhere to these parts, making them prone to breakdowns, and new drawbacks arise, such as the opening and closing of the shutter not being smooth.

である。 The shutter drive mechanism 6 has a guide shaft 15 and a drive screw shaft 16 vertically arranged with the shutter 5 in between, and is rotatably supported by hanging pieces 17, 17 hanging from the lower end of the lower shutter piece 10. A cylindrical body 19 slidably fitted to the guide shaft 15 is fixed to one end of the connecting shaft 18, and a female threaded cylinder 20 screwed to the drive threaded shaft 16 is fixed to the other end.
Further, a screw gear 21 fixed to the lower end of the drive screw shaft 16 is meshed with a screw gear 22 fixed to the output shaft of the motor 7 which can rotate forward and backward. Incidentally, the drive screw shaft 16 is rotatably provided upright.

４の屋外側々面に設けたパツキングである。 In addition, 23 is a double-throw switch operated by manual operation, 24 is a frame that connects the outdoor opening edge of the ventilation shell 2 and the outer frame 1, and 25 is the frame 2.
This is the packing provided on the outdoor sides of No. 4.
また、電気的構成は次のとおりである。 Further, the electrical configuration is as follows.

点ｏと商用交番電源の他方の端子との間にモータ
４を接続している。 The switching contact of the switch 23 is connected to one terminal of the commercial alternating power supply, and the common terminal of the motor 7 is connected to the other terminal, and one contact a of the switch 23 is connected to the switch 9 to reverse the rotation of the motor 7. terminal, and the other contact b is connected from the switching contact of the switch 8 to the normal rotation terminal of the motor 7 via the normally closed contact c, and further, the normally open contact o of the switch 8 is connected to the other contact of the commercial alternating power supply. A motor 4 is connected between the terminals.
以上の構成になる換気扇の作用は次のとおりで
ある。 The function of the ventilation fan configured as above is as follows.
換気扇不使用時には、雌螺筒２０が下降した状
態であり従つてシヤツター５にて、通風胴２の屋
外側開口端部を気密的に閉塞している。 When the ventilation fan is not in use, the female screw tube 20 is in a lowered state and the shutter 5 hermetically closes the outdoor opening end of the ventilation barrel 2.
換気扇を使用する場合には、スイツチ２３を手
動操作して切換接点を接点ｂ側に切り換えれば良
く、スイツチ８の切換接点が常閉接点ｃと接触し
ていることから先ずモータ７が正転して、駆動螺
軸１６を常時一方向に回転駆動する。 When using a ventilation fan, it is only necessary to manually operate the switch 23 and switch the switching contact to the contact b side.Since the switching contact of the switch 8 is in contact with the normally closed contact c, the motor 7 must first rotate in the normal direction. As a result, the drive screw shaft 16 is always rotated in one direction.
従つて雌螺筒２０が上昇し、該雌螺筒２０の上
昇に伴つてシヤツター５が屈曲されることとな
る。 Therefore, the female screw tube 20 rises, and as the female screw tube 20 rises, the shutter 5 is bent.
そして、雌螺筒２０がスイツチ８の作動片を押
圧する位置まで上昇すると、第１図中二点破線で
示すようにシヤツター５が完全な２つ折り状態と
なると同時にスイツチ８の切換接点が常開接点ｏ

タ４が作動して換気動作を行う。 When the female screw cylinder 20 rises to a position where it presses the actuating piece of the switch 8, the shutter 5 is completely folded in half, as shown by the two-dot broken line in FIG. Contact o
Since the motor 7 comes into contact with the ventilator, the motor 7 is stopped and the motor 4 is activated to perform a ventilation operation.

示すようにシヤツター５が完全に通風胴を蔽うと
同時にスイツチ９がOFFとなつてモータ７が停
止する。 In order to stop the ventilation fan, it is only necessary to manually operate the switch 23 so that the switching contact contacts the contact a side, and at the same time, the power to the motor 4 is immediately stopped, since the switch 9 is in the ON state, the switch 23 is in the ON state. is reversed, and the female screw tube 20 is lowered in the opposite manner to the above. When the female screw cylinder 20 descends to the position where it presses the actuating piece of the switch 9, the shutter 5 completely covers the ventilation barrel as shown by the solid line in FIG. Stop.

の効果を奏する。 As described above, in the present invention, the ventilation shell can be isolated from the outside air by the shutter provided outside the ventilation shell, so it is possible to completely eliminate the space between the shutter and the ventilation shell. In addition, since the shutter is opened and closed by a combination of a screw shaft and a screw tube, it can be made compact and operate smoothly.Furthermore, since the shutter can be folded in two, the It has unique effects such as fewer landing points and easier adjustment of the positional relationship of each part.
