　しかしながら、上記特許文献１に開示される換気扇は、組み付けの際は換気扇の本体枠内でシャッター板全体を弾性変形させる必要があるが、組み付け性を良くしたシャッター板は、シャッター板面に強い外力を受けるとシャッター板両側の保持孔間寸法が小さくなる形状に変形し、シャッター板取付軸から脱落する。また、平板形状に起因する反りといった成形不良も発生しやすい。一方、脱落しにくいように強度を持たせたシャッター板は、弾性変形しにくいため、組み付け性が低下し、部品の破損を招く可能性があるという問題があった。 However, the ventilation fan disclosed in Patent Document 1 needs to elastically deform the entire shutter plate within the body frame of the ventilation fan when assembled, but the shutter plate with improved assemblability has a strong external force on the shutter plate surface. If it receives, it will deform | transform into the shape where the dimension between the holding holes of both sides of a shutter plate becomes small, and will drop from a shutter plate mounting shaft. Also, molding defects such as warpage due to the flat plate shape are likely to occur. On the other hand, since the shutter plate having a strength so as not to drop off is difficult to be elastically deformed, there is a problem that the assembling property is lowered and the component may be damaged.

　本体枠２の室内側、すなわち空気の流入側には、オリフィス板４が着脱自在に設けられる。オリフィス板４は、本体枠２とファン７との隙間を塞いで、室内の空気をファン７に導く風洞の働きをする。なお、オリフィス板４は、合成樹脂又は金属で形成されており、フィルタ又はメッシュガードが取り付けられているものもあるが、図１においてはフィルタ又はメッシュガードの図示を省略する。 The orifice plate 4 is detachably provided on the indoor side of the main body frame 2, that is, on the air inflow side. The orifice plate 4 functions as a wind tunnel that closes the gap between the main body frame 2 and the fan 7 and guides indoor air to the fan 7. Although the orifice plate 4 is made of synthetic resin or metal and has a filter or mesh guard attached thereto, the filter or mesh guard is not shown in FIG.
　オリフィス板４には、油受け５が着脱自在に取り付けられる。油受け５は、換気扇１が台所に据付けられた際に、調理時に排出する油煙に含まれた油がオリフィス板４に付着し、オリフィス板４を伝い流下した油を捕集する機能を有する。オリフィス板４から油受け５を取り外すことで、油受け５の内部に溜まった油を容易に捨てることができる。なお、油受け５は、オリフィス板４と一体であってもよい。 The oil pan 5 is detachably attached to the orifice plate 4. The oil receiver 5 has a function of collecting oil contained in the smoke smoke discharged during cooking when the ventilation fan 1 is installed in the kitchen, and collecting the oil flowing down through the orifice plate 4. By removing the oil receiver 5 from the orifice plate 4, the oil accumulated in the oil receiver 5 can be easily discarded. The oil receiver 5 may be integrated with the orifice plate 4.
　本体枠２の室外側には、室外側開口を開閉する複数のシャッター板９が設けられている。シャッター板９は、樹脂で形成されている。シャッター板９は、ファン７が発生させる換気流の風圧によって、上下へ回動し、横向きとなることで風路を開き、ファン７が停止すると自重により下方へ回動して下向きとなり風路を閉じる。シャッター板９が風路を閉じることにより、換気扇１の停止時には室内外の空気の移動が抑制されるため、室内温度を安定させることができる。 A plurality of shutter plates 9 for opening and closing the outdoor opening are provided on the outdoor side of the main body frame 2. The shutter plate 9 is made of resin. The shutter plate 9 pivots up and down by the wind pressure of the ventilation flow generated by the fan 7 and opens to the side when the fan 7 stops. close. Since the shutter plate 9 closes the air path, the movement of the air inside and outside the room is suppressed when the ventilation fan 1 is stopped, so that the room temperature can be stabilized.
　電動機３は、シャフト６を回転させることにより、シャフト６に取り付けられたファン７を回転駆動させる。ファン７は、シャフト６にスピンナー８が着脱自在に嵌め込まれており、換気扇１が固定された状態において、本体枠２の室内側の空気と、室外側の空気とを換気する。 The electric motor 3 rotates and drives the fan 7 attached to the shaft 6 by rotating the shaft 6. In the fan 7, the spinner 8 is detachably fitted to the shaft 6, and the indoor air and the outdoor air of the main body frame 2 are ventilated in a state where the ventilation fan 1 is fixed.
　図２は、実施の形態１に係る換気扇の本体枠の斜視図である。本体枠２の室外側の開口端の両側面には、シャッター板取付軸２０ａ，２０ｂ，２０ｃ，２０ｄが設けられている。シャッター板取付軸２０ａ，２０ｂ，２０ｃ，２０ｄは、本体枠２と一体に形成されており、分離不能である。 FIG. 2 is a perspective view of the main body frame of the ventilation fan according to the first embodiment. Shutter plate mounting shafts 20a, 20b, 20c, and 20d are provided on both side surfaces of the opening end of the main body frame 2 on the outdoor side. The shutter plate mounting shafts 20a, 20b, 20c, and 20d are formed integrally with the main body frame 2 and cannot be separated.
　図３は、実施の形態１に係る換気扇のシャッター板の概略図である。シャッター板９は、本体枠２の室外側の開口を開閉する板状の平板部９ａと、平板部９ａの一端部から立ち上がる耳部４０ｃと、平板部９ａの他端部から耳部４０ｃと同じ方向に立ち上がる耳部４０ａとを備えている。耳部４０ｃには保持孔５０ｃが設けられている。耳部４０ａには保持孔５０ａが設けられている。 FIG. 3 is a schematic diagram of the shutter plate of the ventilation fan according to the first embodiment. The shutter plate 9 is the same as the plate-shaped flat plate portion 9a for opening and closing the outdoor opening of the main body frame 2, the ear portion 40c rising from one end portion of the flat plate portion 9a, and the ear portion 40c from the other end portion of the flat plate portion 9a. Ear part 40a rising in the direction. The ear portion 40c is provided with a holding hole 50c. The ear portion 40a is provided with a holding hole 50a.
　図４は、実施の形態１に係る換気扇のシャッター板取付軸の拡大図である。シャッター板取付軸２０ａの室外側には、先端に近づくほど軸芯からの距離が小さくなる案内面２１が設けられている。実施の形態１において、案内面２１は、先端に近づくにつれて一定の割合で軸芯からの距離が小さくなるテーパ面となっている。また、シャッター板取付軸２０ａには、本体枠２の軸方向と垂直なパーティングライン痕２５が、中心を通っている。すなわち、本体枠２の作成用の金型は、パーティングラインがシャッター板取付軸２０ａの中心にくるように設計されている。これにより、本体枠２の作成用の金型にスライドを追加する必要がなく、金型構造を簡略化でき、本体枠２の作成用の金型の製造コストを低減できる。ここではシャッター板取付軸２０ａについて説明したが、シャッター板取付軸２０ｂ，２０ｃ，２０ｄについても同様の構造である。 FIG. 4 is an enlarged view of the shutter plate mounting shaft of the ventilation fan according to the first embodiment. A guide surface 21 is provided on the outdoor side of the shutter plate mounting shaft 20a so that the distance from the shaft core decreases as it approaches the tip. In the first embodiment, the guide surface 21 is a tapered surface that decreases in distance from the shaft core at a constant rate as it approaches the tip. A parting line mark 25 perpendicular to the axial direction of the main body frame 2 passes through the center of the shutter plate mounting shaft 20a. That is, the mold for creating the main body frame 2 is designed such that the parting line is at the center of the shutter plate mounting shaft 20a. Thereby, it is not necessary to add a slide to the mold for creating the main body frame 2, the mold structure can be simplified, and the manufacturing cost of the mold for creating the main body frame 2 can be reduced. Although the shutter plate mounting shaft 20a has been described here, the shutter plate mounting shafts 20b, 20c, and 20d have the same structure.
　次に、シャッター板９の本体枠２への組立方法について説明する。図５及び図６は、実施の形態１に係る換気扇の本体枠とシャッター板との結合部分の斜視図であり、図５は、シャッター板連動板３０が設置される側を示し、図６は、シャッター板連動板３０が設置されない側を示す。図５に示すように、シャッター板連動板３０を組み付けたシャッター板９の耳部４０ｃに設けられている保持孔５０ｃに、シャッター板取付軸２０ｃを挿入する。次に、図６に示すように、シャッター板取付軸２０ｃに対向して設置されているシャッター板取付軸２０ａの案内面２１に耳部４０ａを押し当てながら押し込む。この際に、耳部４０ａは、案内面２１によりシャッター板取付軸２０ａの先端側に案内されて弾性変形して撓む。耳部４０ａが撓んだ状態で、シャッター板取付軸２０ａは、保持孔５０ａに挿入される。 Next, a method for assembling the shutter plate 9 to the main body frame 2 will be described. 5 and 6 are perspective views of a portion where the main body frame and the shutter plate of the ventilation fan according to Embodiment 1 are joined. FIG. 5 shows a side where the shutter plate interlocking plate 30 is installed, and FIG. The side where the shutter plate interlocking plate 30 is not installed is shown. As shown in FIG. 5, the shutter plate mounting shaft 20c is inserted into the holding hole 50c provided in the ear portion 40c of the shutter plate 9 to which the shutter plate interlocking plate 30 is assembled. Next, as shown in FIG. 6, the ear portion 40a is pressed against the guide surface 21 of the shutter plate mounting shaft 20a installed facing the shutter plate mounting shaft 20c. At this time, the ear portion 40a is guided to the distal end side of the shutter plate mounting shaft 20a by the guide surface 21 and is elastically deformed and bent. With the ear portion 40a bent, the shutter plate mounting shaft 20a is inserted into the holding hole 50a.
　なお、上記とは逆の順番で、保持孔５０ａにシャッター板取付軸２０ａを挿入した後に、保持孔５０ｃにシャッター板取付軸２０ｃを挿入しても良い。 The shutter plate mounting shaft 20c may be inserted into the holding hole 50c after the shutter plate mounting shaft 20a is inserted into the holding hole 50a in the reverse order.
　シャッター板取付軸２０ａ，２０ｃの室内側には案内面２１が無いため、シャッター板９が本体枠２から脱落することは抑制される。 Since there is no guide surface 21 on the indoor side of the shutter plate mounting shafts 20a and 20c, the shutter plate 9 is prevented from falling off the main body frame 2.
　シャッター板取付軸２０ｂ，２０ｄに対しても、シャッター板取付軸２０ａ，２０ｃと同様の手順でシャッター板９を取り付けることができる。 The shutter plate 9 can be attached to the shutter plate attachment shafts 20b and 20d in the same procedure as the shutter plate attachment shafts 20a and 20c.
　実施の形態１に係る換気扇は、シャッター板９を本体枠２に組み付ける際に、シャッター板９の平板部９ａを弾性変形させる必要がなく、耳部４０ａを弾性変形させるだけで組み付けが可能である。したがって、平板部９ａに剛性を持たせることができ、設計の自由度が増すとともに、反りといった成形不良が軽減される。 The ventilation fan according to Embodiment 1 does not need to elastically deform the flat plate portion 9a of the shutter plate 9 when the shutter plate 9 is assembled to the main body frame 2, and can be assembled only by elastically deforming the ear portion 40a. . Therefore, the flat plate portion 9a can be provided with rigidity, so that the degree of freedom in design is increased and molding defects such as warpage are reduced.
　なお、上記の説明では、シャッター板取付軸２０ａ，２０ｂ，２０ｃ，２０ｄが同様の構造であるとしたが、同じシャッター板９が取り付けられるシャッター板取付軸２０ａ，２０ｃの一方と、シャッター板取付軸２０ｂ，２０ｄの一方とに案内面２１を設けるようにしてもよい。この場合には、案内面２１を備えない方のシャッター板取付軸を先に保持孔に挿入し、その後、案内面２１を備える方のシャッター板取付軸に耳部を押し込んで保持孔に挿入すれば良い。 In the above description, the shutter plate mounting shafts 20a, 20b, 20c, and 20d have the same structure, but one of the shutter plate mounting shafts 20a and 20c to which the same shutter plate 9 is mounted and the shutter plate mounting shaft. You may make it provide the guide surface 21 in one of 20b, 20d. In this case, the shutter plate mounting shaft without the guide surface 21 is first inserted into the holding hole, and then the ear portion is pushed into the shutter plate mounting shaft with the guide surface 21 and inserted into the holding hole. It ’s fine.
