　以下に、本発明の実施の形態に係る換気扇を図面に基づいて詳細に説明する。なお、この実施の形態によりこの発明が限定されるものではない。 Hereinafter, a ventilation fan according to an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.
実施の形態１．
　図１は、本発明の実施の形態１に係る換気扇の設置状態における分解斜視図である。図１に示すように、換気扇１は、中央が開口した枠状のフレーム２と、枠状のフレーム２の内部に固定された電動機３とを備える。換気扇１は、枠状のフレーム２にオリフィス４が設けられ、オリフィス４には油受け５が取り付けられる。枠状のフレーム２の内部には電動機３が設けられ、電動機３のシャフト６にファン７が取り付けられ、ファン７の中央部にスピンナー８が取り付けられる。すなわち、ファン７は、枠状のフレーム２の内側に設置される。 Embodiment 1 FIG.
FIG. 1 is an exploded perspective view of the ventilation fan according to Embodiment 1 of the present invention in an installed state. As shown in FIG. 1, the ventilation fan 1 includes a frame-shaped frame 2 having an open center, and an electric motor 3 fixed inside the frame-shaped frame 2. In the ventilation fan 1, an orifice 4 is provided in a frame-like frame 2, and an oil receiver 5 is attached to the orifice 4. An electric motor 3 is provided inside the frame-shaped frame 2, a fan 7 is attached to the shaft 6 of the electric motor 3, and a spinner 8 is attached to the center of the fan 7. That is, the fan 7 is installed inside the frame-like frame 2.
　換気扇１は、建物の壁面に形成された換気扇取付穴１０に挿入された木枠１１などに固定され、ファン７を回転駆動させることにより、室内側の空気と、室外側の空気との間に空気の流れを形成し、室内を換気する。すなわち、換気扇１は、木枠１１が設置された壁面の換気扇取付穴１０に枠状のフレーム２が挿入された状態で固定される。 The ventilation fan 1 is fixed to a wooden frame 11 or the like inserted into a ventilation fan mounting hole 10 formed on the wall surface of the building, and the fan 7 is driven to rotate, so that the indoor air and the outdoor air are interposed. Create an air flow and ventilate the room. That is, the ventilation fan 1 is fixed in a state where the frame-shaped frame 2 is inserted into the ventilation fan mounting hole 10 on the wall surface on which the wooden frame 11 is installed.
　枠状のフレーム２は、換気扇１全体を支持する強度を有し、樹脂で矩形状に形成されたものである。枠状のフレーム２は、室内側と室外側とが開口している。なお、枠状のフレーム２は、上記説明の形状に限定するものではなく、例えば形状は円形状であってもよく、材質は金属鋼板で形成されているものであってもよい。枠状のフレーム２を樹脂製とすることにより、型を用いての量産が可能となり、製造コストを低減できる。 The frame-shaped frame 2 has a strength to support the entire ventilation fan 1 and is formed in a rectangular shape with resin. The frame-like frame 2 is open at the indoor side and the outdoor side. The frame-like frame 2 is not limited to the shape described above. For example, the shape may be a circular shape, and the material may be a metal steel plate. By making the frame-like frame 2 made of resin, mass production using a mold becomes possible, and the manufacturing cost can be reduced.
　枠状のフレーム２の室内側、すなわち空気の流入側には、オリフィス４が着脱自在に設けられる。オリフィス４は、枠状のフレーム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４は、合成樹脂又は金属で形成されており、フィルター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ー又はメッシュガードの図示を省略する。 The orifice 4 is detachably provided on the indoor side of the frame-like frame 2, that is, on the air inflow side. The orifice 4 functions as a wind tunnel that closes a gap between the frame-shaped frame 2 and the fan 7 and guides indoor air to the fan 7. Note that the orifice 4 is made of synthetic resin or metal and has a filter or mesh guard attached thereto, but the filter or mesh guard is not shown in FIG.
　オリフィス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４に付着し、オリフィス４を伝い流下した油を捕集する機能を有する。その内部に溜まった油を捨てる際は、オリフィス４から油受け５を取り外すことで容易に捨てることができる。なお、油受け５は、オリフィス４と一体であってもよい。 The oil receiver 5 is detachably attached to the orifice 4. When the ventilation fan 1 is installed in the kitchen, the oil receiver 5 has a function of collecting oil contained in oil smoke discharged during cooking on the orifice 4 and collecting the oil flowing down through the orifice 4. When discarding the oil accumulated in the inside, it can be easily discarded by removing the oil receiver 5 from the orifice 4. The oil receiver 5 may be integrated with the orifice 4.
　枠状のフレーム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 frame-like 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、電動機３に設けられたシャフト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、枠状のフレーム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 the shaft 6 provided on the electric motor 3 to rotate the fan 7 attached to 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 frame-like frame 2 are ventilated in a state where the ventilation fan 1 is fixed.
　図２は、実施の形態１に係る換気扇の枠状のフレームの斜視図である。図２に示すように、枠状のフレーム２は、木枠１１に挿入される筒部２ａを有する。筒部２ａの室内側の端部には、室内側壁面に沿うように、上側縁部には上フランジ部２０が設けられており、左側縁部には左フランジ部３０が設けられており、右側縁部には右フランジ部４０が設けられており、フランジ下側縁部には下フランジ部５０が設けられている。以下、上フランジ部２０、左フランジ部３０、右フランジ部４０及び下フランジ部５０を総称するときはフランジ部６０という。筒部２ａとフランジ部６０とは一体成形されている。フランジ部６０は、換気扇取付穴１０よりも外形が大きくなっているため、筒部２ａを木枠１１に挿入した際には、筒部２ａから立ち上がる面は木枠１１に当接する。以下、フランジ部６０の筒部２ａから立ち上がる面を当接面６０ａという。 FIG. 2 is a perspective view of the frame-shaped frame of the ventilation fan according to the first embodiment. As shown in FIG. 2, the frame-like frame 2 has a cylindrical portion 2 a that is inserted into the wooden frame 11. An upper flange portion 20 is provided at the upper edge portion, and a left flange portion 30 is provided at the left edge portion along the indoor side wall surface at the indoor side end of the cylindrical portion 2a. A right flange portion 40 is provided at the right edge portion, and a lower flange portion 50 is provided at the flange lower edge portion. Hereinafter, the upper flange portion 20, the left flange portion 30, the right flange portion 40, and the lower flange portion 50 are collectively referred to as a flange portion 60. The cylinder part 2a and the flange part 60 are integrally molded. Since the outer shape of the flange portion 60 is larger than that of the ventilation fan mounting hole 10, the surface rising from the cylindrical portion 2 a comes into contact with the wooden frame 11 when the cylindrical portion 2 a is inserted into the wooden frame 11. Hereinafter, the surface rising from the cylindrical portion 2a of the flange portion 60 is referred to as a contact surface 60a.
　上フランジ部２０には、換気扇１を固定するためのねじ固定用穴２０ａと斜めねじ打ち案内穴２０ｂとが設けられている。左フランジ部３０には、換気扇１を固定するためのねじ固定用穴３０ａと斜めねじ打ち案内穴３０ｂとが設けられている。右フランジ部４０には、換気扇１を固定するためのねじ固定用穴４０ａと斜めねじ打ち案内穴４０ｂとが設けられている。下フランジ部５０には、換気扇１を固定するためのねじ固定用穴５０ａと斜めねじ打ち案内穴５０ｂとが設けられている。ねじ固定用穴２０ａ，３０ａ，４０ａ，５０ａは、当接面６０ａに垂直であり、斜めねじ打ち案内穴２０ｂ，３０ｂ，４０ｂ，５０ｂは、木枠１１との当接面６０ａに対して傾きを有する。 The upper flange portion 20 is provided with a screw fixing hole 20a for fixing the ventilation fan 1 and an oblique screwing guide hole 20b. The left flange portion 30 is provided with a screw fixing hole 30a for fixing the ventilation fan 1 and an oblique screw driving guide hole 30b. The right flange portion 40 is provided with a screw fixing hole 40a for fixing the ventilation fan 1 and an oblique screwing guide hole 40b. The lower flange portion 50 is provided with a screw fixing hole 50a for fixing the ventilation fan 1 and an oblique screw driving guide hole 50b. The screw fixing holes 20a, 30a, 40a, 50a are perpendicular to the contact surface 60a, and the oblique screwing guide holes 20b, 30b, 40b, 50b are inclined with respect to the contact surface 60a with the wooden frame 11. Have.
　次に、換気扇１の木枠１１への固定方法について説明する。作成した木枠１１を建物の壁面などに形成された換気扇取付穴１０に対して挿入し、換気扇取付穴１０と木枠１１との隙間をコーキング剤で埋めて固定する。換気扇取付穴１０に固定した木枠１１に、室内側から枠状のフレーム２を挿入する。 Next, a method for fixing the ventilation fan 1 to the wooden frame 11 will be described. The created wooden frame 11 is inserted into the ventilation fan mounting hole 10 formed on the wall surface of the building, and the gap between the ventilation fan mounting hole 10 and the wooden frame 11 is filled with a caulking agent and fixed. The frame-like frame 2 is inserted into the wooden frame 11 fixed to the ventilation fan mounting hole 10 from the indoor side.
　木枠１１は、板厚が２０ｍｍから３０ｍｍ程度であり、木枠内寸法は、枠状のフレーム２の外形寸法よりも１ｍｍから５ｍｍ程度大きい範囲で、施工業者又はエンドユーザによって現地で作成される。そのため、枠状のフレーム２を木枠１１に挿入するだけでは、換気扇１を壁面に固定することはできない。 The wooden frame 11 has a plate thickness of about 20 mm to 30 mm, and the dimensions inside the wooden frame are created on site by a contractor or end user within a range that is about 1 mm to 5 mm larger than the outer dimensions of the frame-like frame 2. . Therefore, the ventilation fan 1 cannot be fixed to the wall surface simply by inserting the frame-like frame 2 into the wooden frame 11.
　したがって、換気扇１を固定するために、換気扇１の枠状のフレーム２の上下左右の縁部から室内側壁面に向けて沿うように形成されたフランジ部６０に設けられたねじ固定用穴２０ａ，３０ａ，４０ａ，５０ａにより木ねじを木枠１１に打ち込む。 Therefore, in order to fix the ventilation fan 1, the screw fixing holes 20a provided in the flange portion 60 formed so as to extend from the upper, lower, left and right edges of the frame-like frame 2 of the ventilation fan 1 toward the indoor side wall surface, A wood screw is driven into the wooden frame 11 by 30a, 40a, 50a.
　取付説明書又は取扱説明書に記載の推奨寸法通りに作成された木枠１１に換気扇１を固定する場合は、ねじ固定用穴２０ａ，３０ａ，４０ａ，５０ａから木枠１１に木ねじを打ち込むことで強固に当接させることができ、換気扇１を固定することができる。 When the ventilation fan 1 is fixed to the wooden frame 11 prepared according to the recommended dimensions described in the installation manual or the instruction manual, the wood screw is driven into the wooden frame 11 from the screw fixing holes 20a, 30a, 40a, 50a. It can be made to contact firmly and the ventilation fan 1 can be fixed.
　一方、作業現場にて作成された木枠１１が推奨寸法通りに作成されておらず、ねじ固定用穴２０ａ，３０ａ，４０ａ，５０ａから木枠１１が外れてしまい、木ねじを打ち込めない場合であっても、斜めねじ打ち案内穴２０ｂ，３０ｂ，４０ｂ，５０ｂを用いることで、片側に寄せて換気扇１を取り付けたり、木枠１１を再作成したり、木枠１１と換気扇１との隙間を埋めたりするといった対応が不要となる。すなわち、木枠１１が推奨寸法通りに作成されていなくても、斜めねじ内案内穴２０ｂ，３０ｂ，４０ｂ，５０ｂを用いることで、換気扇１を容易に固定できる。 On the other hand, the wooden frame 11 prepared at the work site is not prepared according to the recommended dimensions, and the wooden frame 11 is detached from the screw fixing holes 20a, 30a, 40a, 50a, and the wooden screw cannot be driven. However, by using the oblique screwing guide holes 20b, 30b, 40b, 50b, the ventilation fan 1 is attached to one side, the wooden frame 11 is recreated, or the gap between the wooden frame 11 and the ventilation fan 1 is filled. Or the like. That is, even if the wooden frame 11 is not created according to the recommended dimensions, the ventilation fan 1 can be easily fixed by using the guide holes 20b, 30b, 40b, and 50b in the oblique screw.
　図３は、実施の形態１に係る換気扇の斜めねじ打ち案内穴付近の拡大斜視図である。図４は、実施の形態１に係る換気扇の斜めねじ打ち案内穴の部分の断面図である。なお、ここでは斜めねじ打ち案内穴３０ｂについて説明するが、斜めねじ打ち案内穴２０ｂ，４０ｂ，５０ｂについても同様である。図３に示すように、斜めねじ打ち案内穴３０ｂは、角穴となっている。斜めねじ打ち案内穴３０ｂを角穴とすることで、枠状のフレーム２の作成用の金型の構造が複雑とならず金型作成のコストの低減を図ることができる。また、斜めねじ打ち案内穴３０ｂのねじ打ち角度θを大きくとることで、木枠１１へ木ねじを打ち込む際のガイドを長くでき、より容易にねじ打ちを行える。さらに、木枠１１との許容隙間幅Ｌを広げることが可能となる。ここで、ねじ打ち角度θは、斜めねじ打ち案内穴３０ｂの当接面６０ａに対する傾きであり、ねじ打ち角度θが大きくなるほど木ねじが木枠１１に対して傾斜した状態でねじ込まれることとなる。 FIG. 3 is an enlarged perspective view of the vicinity of the oblique screwing guide hole of the ventilation fan according to the first embodiment. FIG. 4 is a cross-sectional view of a portion of the oblique screw driving guide hole of the ventilation fan according to the first embodiment. Here, the oblique screwing guide hole 30b will be described, but the same applies to the oblique screwing guide holes 20b, 40b, and 50b. As shown in FIG. 3, the oblique screwing guide hole 30b is a square hole. By making the oblique screwing guide hole 30b into a square hole, the structure of the mold for creating the frame-like frame 2 is not complicated, and the cost for creating the mold can be reduced. Further, by increasing the screwing angle θ of the oblique screwing guide hole 30b, the guide for driving the wooden screw into the wooden frame 11 can be lengthened, and screwing can be performed more easily. Furthermore, the allowable gap width L with the wooden frame 11 can be increased. Here, the screwing angle θ is an inclination with respect to the contact surface 60a of the oblique screwing guide hole 30b, and the wood screw is screwed in a state inclined with respect to the wooden frame 11 as the screwing angle θ increases.
　このように、実施の形態１によれば、斜めねじ打ち案内穴２０ｂ，３０ｂ，４０ｂ，５０ｂを用いることで、片側に寄せて換気扇１を取り付けたり、木枠１１を再作成したり、木枠１１と換気扇１との隙間を埋めたりするといった対応が不要となる。 As described above, according to the first embodiment, by using the oblique screwing guide holes 20b, 30b, 40b, and 50b, the ventilation fan 1 is attached to one side, the wooden frame 11 is recreated, The correspondence of filling the gap between the fan 11 and the ventilation fan 1 becomes unnecessary.
実施の形態２．
　図５は、本発明の実施の形態２に係る換気扇の斜めねじ打ち案内穴付近の拡大斜視図である。実施の形態２においては、斜めねじ打ち案内穴３０ｂは、丸穴となっている。斜めねじ打ち案内穴３０ｂを丸穴とすると、枠状のフレーム２の作成のための金型の構造は、スライドなどの追加によって幾分複雑となるが、木枠１１に木ねじを打ち込む際に、木ねじと斜めねじ打ち案内穴３０ｂとの接触面積が増加するため、木ねじの打ち込みが容易となる。 Embodiment 2. FIG.
FIG. 5 is an enlarged perspective view of the vicinity of the oblique screw driving guide hole of the ventilation fan according to Embodiment 2 of the present invention. In the second embodiment, the oblique screwing guide hole 30b is a round hole. If the oblique screwing guide hole 30b is a round hole, the structure of the mold for creating the frame-like frame 2 is somewhat complicated due to the addition of a slide or the like. Since the contact area between the wood screw and the oblique screw driving guide hole 30b increases, the wood screw can be driven easily.
　斜めねじ打ち案内穴３０ｂについて説明したが、斜めねじ打ち案内穴２０ｂ，４０ｂ，５０ｂについても同様である。 The oblique screwing guide hole 30b has been described, but the same applies to the oblique screwing guide holes 20b, 40b, and 50b.
　斜めねじ打ち案内穴２０ｂ，３０ｂ，４０ｂ，５０ｂ以外の部分は、実施の形態１と同様であるため、説明は省略する。 Since the portions other than the oblique screwing guide holes 20b, 30b, 40b, 50b are the same as those in the first embodiment, the description thereof is omitted.
