A simultaneous intake and exhaust type ventilation fan to which the present invention is applied is generally constructed as shown in FIG. That is, the inside of a main body frame 1 formed in a rectangular cylindrical shape is partitioned from side to side by partition plates 2 to form an exhaust passage 3 and an intake passage 4. And this exhaust path 3 and intake path 4
As shown in FIGS. 6 and 7, the shutter 5, which opens and closes at the same time, is provided with a guide partition plate 6 that is close to or in contact with the partition plate 2. In these drawings, 7 is the flange of the main body frame 1, 8 is the switch provided on the flange 7, 9 is the drawstring of the switch 8, 10 is the actuator of the switch 8, O is the pivot point of the shutter 5, and 11 is the aforementioned This is a rod that connects the actuator 10 and the shutter 5.

つてシヤツタが閉じないという問題がある。
As mentioned above, since the inner edge of the guide partition plate 6 provided in the conventional shutter 5 is straight, the opening angle of the shutter 5 is restricted to θ1 . However, if the shutter 5 is opened forcefully, the arc portion R may separate from the main body frame 1 as shown in FIG. 7, and at this time, if the guide partition plate 6 is deformed as shown in FIG. There is a problem in that the shutter does not close because the partition plate 6 hits the partition plate 2.
本発明は、シヤツタの開放角度を実質的に増大
し、又、開閉動作をスムーズなシヤツタ装置を提
供することである。 SUMMARY OF THE INVENTION An object of the present invention is to provide a shutter device that substantially increases the opening angle of the shutter and allows smooth opening and closing operations.

The present invention provides a shutter device for a simultaneous intake/exhaust type ventilation fan, in which a guide partition plate provided on the shutter is provided with a line that intersects a line that is directed downward at an angle θ 1 of 90 degrees or less with respect to the shutter at its inner end. Similarly, a protrusion formed by a line formed at an angle θ 2 of 90 degrees or more with respect to the shutter and a circular arc portion R centered on the pivot point O is provided.

The protrusion 61 of the guide partition plate 6 does not separate from the main body frame 1 even if the shutter 5 is opened at an angle greater than the specified angle, so the shutter 5 is reliably closed and the line 6
Since the angle θ 2 that determines B is set to 90 degrees or more, even if the guide partition plate 6 butts against the partition plate 2, the two act so as to contact each other and perform the closing operation while being guided by sliding.
次に本発明の一実施例を第１図ないし第４図に

ある。 FIG. 1 shows a guide partition plate 6 provided on the shutter 5.
shows a side view. The guide partition plate 6 has a line 6A having an angle of 90 degrees or less with the pivot point O as the center, a line 6B that intersects this line 6A and has an angle of 90 degrees or more with respect to the shutter 5, and the pivot point. It is formed in a shape surrounded by a circular arc portion R with O as the center. A portion 61 is a protrusion that remains within the main body frame 1 in the opened and closed state as shown in FIGS. 3 and 4. The reason why the angle θ 2 is set to 90 degrees or more is so that even if the line 6B hits the partition plate 2, both will slide and the shutter 5 will close smoothly.
尚、開放角度やスムースな開閉動作をさせるた
めには第２図のように角度θ１よりも大きな角度
θ３でなされる線６Ｃとし、突出部６１を設けな
いものでも同様に達成できるが、このときは第１

策ではない。 Incidentally, in order to achieve the opening angle and smooth opening/closing operation, the line 6C is set at an angle θ 3 larger than the angle θ 1 as shown in FIG. At this time, the first
Compared to the one shown in the figure, the material indicated by diagonal lines will be wasted, which is not a good idea.

As described above, the present invention provides a guide partition plate provided on a shutter with a line at its inner end that is directed downward at an angle θ 1 of 90 degrees or less with respect to the shutter, and a line that intersects this line and is also attached to the shutter. against 90
This is provided with a protrusion formed by a line with an angle θ 2 greater than 2 degrees and a circular arc portion R centered on the pivot point O, thereby substantially increasing the opening angle of the shutter. Furthermore, it is possible to provide a shutter device for a simultaneous intake/exhaust type ventilation fan whose opening/closing operation is very smooth.
