【考案の詳細な説明】
本考案はシヤツターの開閉とフアンモータの作
動とを連動させる換気扇に関する。[Detailed Description of the Invention] The present invention relates to a ventilation fan that links the opening and closing of a shutter with the operation of a fan motor.
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
ツター片との間に隙間ができ、換気扇不使用時に
室内を外気から完全には遮断し得ないこととなる

風を伴なう降雨の場合には前記隙間から雨水が侵
入する恐れがあり、更には風が強い場合には、風
圧に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 outside air when the ventilation fan is not used, resulting in a decrease in indoor cooling and heating efficiency. As well,
In the case of rain accompanied by wind, there is a risk that rainwater may enter through the gaps, and furthermore, in the case of strong winds, the shutter pieces may flap due to wind pressure, causing unpleasant noise. There are drawbacks.

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, and furthermore, the shutter piece and the connecting piece are connected. As for the structure, the uppermost shutter piece and the connecting piece are rotatably connected by a shaft and a round hole, and the other shutter pieces and connecting pieces are rotatably and slidably connected by a shaft and a long hole. I try to do that.
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
を発生させるという欠点を解消することができる

率が低下するのみならず、風を伴なう降雨の場合
には前記隙間から雨水が侵入する恐れがあるとい
う欠点は解消し得ないのである。 Therefore, with this configuration, it is possible to eliminate the disadvantage that the shutter pieces flap even in strong winds and generate unpleasant noise, but a gap is created between the shutter outer frame and the shutter pieces, and the ventilation fan Since the room cannot be completely isolated from the outside air when not in use, not only will the efficiency of cooling and heating the room decrease, but also there is a risk that rainwater may enter through the gap in the case of rain accompanied by wind. The drawbacks that exist cannot be overcome.

開閉の動作がスムーズでなくなる等の新たな欠点

要とするという欠点がある。 Furthermore, since there are many moving parts, oil droplets etc. can adhere to these parts, making them prone to malfunctions.In addition, new drawbacks arise, such as the shutter opening and closing not being smooth, and it is difficult to operate the shutter opening and closing. It has the disadvantage that excessive effort is required for each operation because it is performed by the human's own strength.

図面によつて詳細に説明する。 The present invention solves the above-mentioned drawbacks by using a bifold shutter, installing the shutter on the outdoor side of the ventilation shell, and opening and closing the shutter using a motor that operates in synchronization with the fan motor. This will be described in detail below with reference to the accompanying drawings showing examples.

である。 The shutter drive mechanism 6 has a guide shaft 15 and a drive screw shaft 16 vertically arranged to sandwich the shutter 5, and is rotatably supported by hanging pieces 17, 17 hanging down 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.

ている。 Further, the electrical configuration is as follows. 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 to the forward rotation terminal of the motor 7 via the switching contact of the switch 8 and the normally closed contact c, and furthermore, the normally open contact o of the switch 8 is connected to the other terminal 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
ていることから先づモータ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 to 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 be in the correct position. 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
昇に伴なつてシヤツター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

タ４が作動して換気動作を行なう。 When the female screw cylinder 20 rises to a position where it presses the operating 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 the ventilation operation.
換気扇を停止させる場合には、スイツチ２３

ータ７が逆転して、前記と逆に雌螺筒２０を下降
させる。 To stop the ventilation fan, press switch 23.
All you have to do is manually operate the switching contact so that it comes into contact with the contact a side.At the same time, the power to the motor 4 is immediately stopped, and since the switch 9 is in the ON state, the motor 7 is reversed, and vice versa. The screw tube 20 is lowered.
そして、雌螺筒２０がスイツチ９の作動片を押
圧する位置まで下降すると、第１図中実線で示す
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。 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.

等特有の効果を奏する。 As described above, in the present invention, since the ventilation shell can be isolated from the outside air by the shutter provided outside the ventilation shell, there is no gap 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 can operate smoothly.Furthermore, since the shutter can be folded in two, there are no pivot points. It has unique effects such as the reduction in the amount of noise, the adjustment of the positional relationship of each part, and the ability to reduce the labor required for operation since the opening and closing operations of the shutter are performed by a motor.
