Description

【0001】
【発明の属する技術分野】
本発明は、送風機を内部に備えたレンジフードファンに係り、特に、整流板の表面に発生する結露を防止するレンジフードファンに関する。
【0002】
【従来の技術】
一般に、この種のレンジフードファンは、特許第2508901号公報や特開2001−4181号公報に記載したように構成されており、調理で発生した燃焼ガスや油煙・蒸気を効率よく捕獲し、送風機により屋外に排出するようになっている。
【0003】
最近では、ガスコンロ、ガスレンジのガス調理器から火災発生の防止を目的として誘導加熱ヒータ(Induction Heating ヒータ:IHヒータ)を利用した電磁調理器が普及しつつある。
【0004】
しかし、調理器具として電磁調理器を採用した場合、レンジフードファンの整流板に結露が発生し、発生した結露が次第に成長して液滴となって滴下する問題が生じることを知見した。
【0005】
レンジフードファンの結露発生問題はガスコンロの場合には生じていない。ガスコンロでは、燃料ガスの燃焼による高温の燃焼ガスが図10に示すようにレンジフードファン1の整流板2に案内されて本体ケーシング(フード本体)3内に案内され、送風機4の吸込口5から吸引されるようになっている。送風機4で吸引された燃焼ガスや蒸気は続いて送風機4から送風され、排出口6より外部に排出されるようになっている。
【0006】
その際、レンジフードファン1の整流板2に導かれて整流板2の吸込口5に案内される空気は、燃焼ガスで加熱されて温まっている。このため、整流板2の表面温度と背面側の裏面温度との間に大きな温度差が生じることがなく、整流板2に結露が生じるのを有効的に防止でき、結露問題が生じることはなかった。
【0007】
しかし、誘導加熱ヒータを備えた電磁調理器を用いると、電磁調理器による調理によって周囲温度が殆ど上昇しない。このため、調理中の鍋から発生する蒸気により、整流板2の下面(表面)は温められるが、整流板2の背面側を流れる空気は温度上昇することが少なく、冷たい。
【0008】
【発明が解決しようとする課題】
冬場や空気調和機の冷房運転中に電磁調理器を用いて調理すると、整流板2の表面(下面)に鍋や薬缶から発生する上昇蒸気が接触して結露が生じ、この結露が次第に成長すると液滴となって滴下する問題があった。発生した結露が水滴等となって滴下すると、調理場を汚し、清潔感が損なわれる問題があった。
【0009】
本発明は、上述した事情を考慮してなされたもので、整流板表面に結露が生じるのを未然にかつ有効的に防止し、調理場を清潔に保つことができるレンジフードファンを提供することを目的とする。
【0010】
本発明の他の目的は、安全性に優れ、清掃を簡単かつスムーズに行なうことができるレンジフードファンを提供することにある。
【0011】
本発明の別の目的は、整流板の取付構造を簡素化して商品性を向上させ、整流板の着脱性やその自由度を向上させたレンジフードファンを提供するにある。
【0012】
【課題を解決するための手段】
本発明に係るレンジフードファンは、上述した課題を解決するために、請求項1に記載したように、本体ケーシング内に送風機を有し、この送風機の吸込口を覆うように整流手段を本体ケーシングのフードに間隔をおいて設けたレンジフードファンにおいて、前記整流手段を偏平断熱構造に構成したものである。
【0013】
また、上述した課題を解決するために、本発明に係るレンジフードファンは、請求項2に記載したように、前記整流手段は、内部に断熱空間層を形成したものであり、さらに、請求項3に記載したように、前記整流手段は、プレート状の下側整流メンバと上側整流メンバとを組み合せて両メンバ間に断熱空間層を形成し、上記下側整流メンバを不燃材料で形成するとともに、少なくとも一方の整流メンバは一面が開口したボックス形状に形成したものであり、さらにまた、請求項4に記載したように、前記上側整流メンバと下側整流メンバは、一面が開口したボックス形状に形成するとともに、開口部同士が対向するように組み合せて一体的に構成したものである。
【0014】
さらに、上述した課題を解決するために、本発明に係るレンジフードファンは、請求項5に記載したように、前記上側整流メンバと下側整流メンバとを組み合わせたとき、少なくとも外側に位置する整流メンバの周辺立上り部を絞り加工により形成したものであり、また、請求項6に記載したように、前記整流手段は、組み合わされる上側整流メンバと下側整流メンバとの間の断熱空間層に断熱材を設けたものであり、さらに、請求項7に記載したように、前記整流手段は、上側整流メンバの周辺立上り部と下側整流メンバの周辺立上り部との間に周方向の側方空間部を設け、この側方空間部に断熱材を設けたものであり、さらにまた、請求項8に記載したように、前記整流手段は、上側整流メンバに本体ケーシングへの係合取付手段を設けたものである。
【0015】
また、上述した課題を解決するために、本発明に係るレンジフードファンは、請求項9に記載したように、前記整流手段は、偏平断熱構造の外表面が撥油性の皮膜で被覆されたものであり、さらに、請求項10に記載したように、前記整流手段は、整流メンバの上面に断熱材を設けたものであり、さらにまた、請求項11に記載したように、前記整流手段は、整流メンバを断熱材料で形成したものであり、またさらに、請求項12に記載したように、前記整流手段の偏平断熱構造は、下面をフラット状に、上面を中央部が窪んだ凹状に形成したものである。
【0016】
【発明の実施の形態】
本発明に係るレンジフードファンの一実施形態について添付図面を参照して説明する。
【0017】
図1は、本発明に係るレンジフードファンの一実施形態を下方から斜め上方に向って見た全体図であり、符号10はレンジフードファンを示す。レンジフードファン10は例えば箱形形状のレンジ本体としての本体ケーシング11を有し、この本体ケーシング11の前面にレンジフードファン10の作動を操作する操作ボタン12が設けられる。本体ケーシング11の下面にフード13が設けられており、このフード13に整流板14が整流手段として間隔をおいて着脱自在に取り付けられる。整流板14は偏平断熱構造に形成され、整流板14とフード13との間に整流板14の周辺から送風機15の吸込口16に至る吸込流路17が形成される。この吸込流路17に沿って空気流が案内されるようになっている。
【0018】
レンジフードファン10の本体ケーシング11内に送風機15が収納される。送風機15は電動モータ18とこのモータ駆動のシロッコ羽根等の送風羽根19とを有し、ファンケーシング20で覆われている。送風機15の吸込口16はフード13のベルマウス22部に開口している。
【0019】
一方、レンジフードファン10の下側に露出するように整流板14が取り付けられており、この整流板14は偏平な矩形のボックス状をなして内部に偏平断熱構造の空気層である断熱空間層23を形成している。整流板14は、矩形形状以外にレンジフードファン10の下面形状に応じて種々任意の形状に形成してもよい。
【0020】
整流板14は、金属等のステンレス材料、不燃性材料等のセラミックス材料で形成される。整流板14の表面および裏面、少なくとも表面は、好ましくはシリコンやフッ素樹脂材料等の撥油性材料でコーティングされ、樹脂被膜が施される。整流板14の清掃を円滑かつスムーズに行なうためである。
【0021】
整流板14は、図3および図4に示すように、プレート状の上側整流メンバ24と下側整流メンバ25とをほぼ同寸法に形成し、上側整流メンバ24および下側整流メンバ25の外周は板金プレス加工による絞り加工により周辺立上り部26が形成され、蓋形状に絞り込まれる。絞り加工で上側整流メンバ24と下側整流メンバ25の外周部を絞り込むと、周辺立上り部26のコーナ部にR部が形成されるため、鋭い折曲部が形成されずに安全性が向上し、外観形状が優れ、商品性を高めることができる。
【0022】
上側整流メンバ24および下側整流メンバ25の外周部は折り曲げ加工で形成してもよい。しかし、折り曲げ加工により両メンバ24,25を形成すると外周コーナ部に鋭い角部に形成されるため、清掃時に注意を要する。上側整流メンバ24および下側整流メンバ25は立上り部26により一面に開口を有する偏平ボックス形状に構成される。
【0023】
外周部に周辺立上り部26を有する上側整流メンバ24と下側整流メンバ25はほぼ同寸法に形成され、圧入・嵌合させることにより、一体的に偏平ボックス形状に構成される。両整流メンバ24,25は、摩擦接合による締結である焼嵌め等により強固に結合される。両整流メンバ24,25の結合は焼嵌め等による圧入嵌合ではなく、溶接等による固着であっても、リベット等による締結であってもよい。両整流メンバ24,25はいずれにしても締結され、一体化されて整流板14が組み立てられる。
【0024】
整流板14の上側整流メンバ24には、図3および図4に示すように、フック形状の引掛け金具28およびロック爪形状の掛止め金具29が係合取付手段として複数個、例えば2個ずつ4隅部に設けられる。その際、整流板14は偏平ボックス形状に形成され、内部に断熱空間層23が形成されているので、各金具28,29を上側整流メンバ24にねじ止め固定でき、取付構造が簡素化され、外観形状も良好となる。整流板14の上面および下面はほぼフラット形状に形成される。また、整流板14の上面、具体的には上側整流メンバ24の上面に***(小孔)を形成してもよい。***は複数個形成してもよい。
【0025】
次にレンジフードファン10の作用について説明する。
【0026】
レンジフードファン10の製造に際しては、フード本体としての本体ケーシング11下部に整流板14を引掛け金具28および掛止め金具29を利用して着脱自在に取り付ける。
【0027】
整流板14は、少なくとも下側整流メンバ25が不燃性材料で形成され、この下側整流メンバ25と上側整流メンバ24の周辺立上り部26,26同士を対向させて組み合わせることにより一体的に偏平断熱構造に構成される。上側整流メンバ24および下側整流メンバ25は、外周部を好ましくは絞り加工により周辺立上り部26を形成する一方、上側整流メンバ24および下側整流メンバ25の表面には撥油性材料の樹脂コーティングが施される。この樹脂コーティングは整流板14を形成した後、この整流板14に外表面に施してもよい。
【0028】
そして、上側整流メンバ24と下側整流メンバ25は各立上り部周辺26,26を対向させて焼嵌め等により嵌合させ、偏平ボックス(円盤)状の整流板14を一体に組み立てる。組み立てられた整流板14の上側整流メンバ24に引掛け金具28および掛止め金具29を取り付け、この引掛け金具28および掛止め金具29を利用して整流板14をフード13に間隔をおいて取り付ける。
【0029】
整流板14のフード13への取付により、整流板14の周辺から送風機15の吸込口16に至る吸込流路17が形成される。送風機15の吸込口部はフード13のベルマウス22により形成され、吸込流路17に案内された空気流が送風機15に下方からスムーズに吸い込まれるようになっている。
【0030】
このようにして、図1および図2に示されるレンジフードファン10が組み立てられ、製造される。製造されたレンジフードファン10は各家庭や店等の調理場に据え付けられる。
【0031】
据え付けられたレンジフードファン10は、送風機15に通電してモータ駆動させることにより作動される。送風機15の作動により、整流板14の周辺から空気が吸込流路17に吸い込まれる。吸込流路17に吸い込まれた空気流はフード13のベルマウス22に案内されて吸込口16から送風機15に吸い込まれる。送風機15に下方から吸い込まれた空気流は続いて半径方向外方に吹き出され、ファンケーシング20に案内されて排出口30から外部に排出される。排出口30には図示しない排気フードが接続され、屋外に排出されるようになっている。
【0032】
このレンジフードファン10においては、送風機15の回転駆動により、室内の空気がフード13と整流板14の間に形成される吸込流路17からベルマウス22に入り、送風機15へ下側から吸い込まれる。吸い込まれた送風機15は、吹出方向が変えられ、ファンケーシング20に案内されて排出口30から屋外へ排出される。
【0033】
その際、電磁調理器の調理により、誘導加熱ヒータの誘導加熱作用により生じた水蒸気や油煙が上昇流となって上昇し、整流板14の下面(表面)に接触する。
【0034】
しかし、整流板14の表面に水蒸気や油煙の上昇流が衝突し、接触しても、整流板14は偏平断熱構造で形成されているので、整流板14表面に結露が生じるのを正確にかつ確実に防止できる。この場合、整流板14は内部に断熱空間層23が形成されており、吸込流路17を通って屋外に排出される空気温度の影響を受けない。
【0035】
また、電磁調理器による調理時に、誤って天ぷら油に火が付いても、整流板14は悪影響を受けない。整流板14は上側整流メンバ24および下側整流メンバ25の周辺立上り部26,26がフード13で上側からカバーされるため、周辺立上り部26,26の結合部が外部に露出するのを有効的に防止でき、外観形状の向上を図ることができる。しかも、各整流メンバ24,25の周辺立上り部26,26を絞り加工で形成することにより、周辺コーナ部にR部が形成される。このために、清掃時に整流板14のコーナ部に手が触れても、怪我をすることがなく、清掃作業を効率よく円滑に行なって、安全性をより向上させることができる。
【0036】
整流板14の外表面、少なくとも表面にシリコン樹脂やフッ素樹脂等の撥油性材料でコーティングすることにより、整流板14の表面に撥油性・撥水性の被膜を施すことができ、清掃作業の作業性が向上し、作業の簡素化、能率化を図ることができる。
【0037】
なお、このレンジフードファン10においては、整流板14を構成する上側整流メンバ24および下側整流メンバ25の外周部に周辺立上り部26,26を形成した例を示したが、この立上り部26は一方の整流メンバ24または25に形成し、他方の整流メンバ(例えば上側整流メンバ24)に形成する必要は必ずしもない。)
次に、本発明に係るレンジフードファンの他の実施形態を図5ないし図9を参照して説明する。
【0038】
図5は、本発明に係るレンジフードファンの第2実施形態を示すもので、レンジフードファンに備えられる整流板14Aの断面構造を示す。この整流板14Aを除いた他の構成は、図1および図2に示すレンジフードファン10と異ならないので、図示を省略する。
【0039】
この整流板14Aは、プレート状の上側整流メンバ24と下側整流メンバ25とを組み合せて偏平断熱構造に形成する技術は、図2ないし図4に示される整流板14と共通するが、上記整流板14Aは、両整流メンバ24,25内に形成される偏平な断熱空気層に断熱材32を充填させたものである。断熱材32としてはガラスウールや独立気泡の断熱材料、例えば発泡ウレタンや発泡スチロールがある。
【0040】
両整流メンバ24,25間の断熱空気層に断熱材32を設けることにより、空気層だけの場合より、より一層整流板25の表面に付着する結露を確実かつ有効的に防止できる。
【0041】
図6は、本発明に係るレンジフードファンに備えられる整流板14Bの第1変形例を示すものである。他の構成は図1および図2に示すものと異ならないので、説明を省略する。
【0042】
この整流板14Bは、プレート状の下側整流メンバ25の周辺部を絞り加工等により周辺立上り部26を形成し、上面が開口した偏平ボックス形状に形成される。そして、下側整流メンバ25のボックス内に形成される空間層23に断熱材33を設けたものである。整流板14Bの周辺立上り部26の一辺にフック状の引掛け金具28が溶接等で複数個取り付けられ、この辺に続く周辺立上り部26の側辺に掛止め金具29がそれぞれ取り付けられる。そして、整流板14Bに取り付けられた引掛け金具28および掛止め金具29により整流板14Bが本体ケーシング11のフード13(図2参照)に着脱自在に取り付けられる。整流板14B自体をセラミックス材料のような不燃性の断熱材料で形成してもよい。この場合には、他の断熱材料は設ける必要はない。
【0043】
この整流板14Bにおいては、下側整流メンバ25の上面に断熱材33を載せると、断熱材33側表面の清掃性が悪化するが、整流板14Bの下面(表面)に付着する結露は解消できるので、結露発生防止に関しては一実施形態に示す整流板14と同等の作用効果を奏することができる。
【0044】
図7は、整流板の第2変形例を示すものである。この変形例に示された整流板14Cは、上側整流メンバ34と下側整流メンバ35との寸法形状を異にして形成したものである。
【0045】
整流板14Cの上側整流メンバ34は下側整流メンバ35と同様に周辺部が絞り加工等により絞られて周辺立上り部36,36が形成され、一面が開口した偏平ボックス形状に構成される。上側整流メンバ34は下側整流メンバ35より1廻り小さな寸法形状に形成され、両整流メンバ34,35は立上り部36,36を対向させて組み合わせることにより一体化される。
【0046】
両整流メンバ34,35を組み合せて一体的に結合したとき、整流板14Cの内部に偏平な断熱空気層37が形成される一方、周辺部に側方空間部38が周方向に形成され、この側方空間部38に断熱材39が設けられる。側方空間部38は下側整流メンバ35の立上り部36と上側整流メンバ34の立上り部36との間に形成される。
【0047】
この整流板14Cの偏平断熱構造によれば、整流板の表面(下面)に発生する結露を防止できる一方、整流板14Cの立上り部36である側壁に結露が生じるのを有効的に防止できる。整流板14Cを除いたレンジフードファンの全体的構成は第1実施形態に示すものと異ならないので、説明を省略する。
【0048】
図8および図9は整流板の第3変形例を示すものである。
【0049】
この変形例に示された整流板14Dは、上側整流メンバ40と下側整流メンバ41のメンバ間に偏平断熱構造の断熱空間層43を形成する構成は、第1実施形態の整流板14と共通する。
【0050】
この整流板14Dは、プレート状の上側整流メンバ40の中央部を凹設して凹部形状に形成する一方、下側整流メンバ41をフラット形状に形成したものである。上側整流メンバ40は中央部に向って下り傾斜する凹状に形成されており、図1および図2に示すレンジフードファン10の送風機15、フード13および整流板14Dに付着した油や水滴を外へ流出させない構造となっている。整流板14Dは送風機15やフード13に付着した油や水滴を整流板14Dの上側整流メンバ40の中央部付近に集める構成となっている。
【0051】
他の構成および作用は、図1ないし図2に示されるレンジフードファンと異ならないので、説明を省略する。符号44は上側整流メンバ40の周辺立上り部、45は下側整流メンバ41の周辺立上り部である。
【0052】
なお、本発明の実施形態では、レンジフードファンにフィルタを備えない例を説明したが、このレンジフードファンにおいても、送風機の吸込側にフィルタを設けてもよいことは勿論である。この場合、フィルタは、空気流の吸込流路に設けて、フード13のベルマウス部に設けてもよい。
【0053】
【発明の効果】
本発明に係るレンジフードファンにおいては、電磁調理器で調理しても整流手段(整流板)の表面に結露が発生するのを未然かつ有効的に防止でき、結露の滴下による調理場の汚損を確実に防止でき、清潔感を保つことができる。
【0054】
また、このレンジフードファンは、整流手段を偏平断熱構造で構成し、整流板を本体ケーシングに簡単かつ容易に着脱させることができ、しかも、不燃性材料で形成したので、火炎の虞もなく安全性を向上させることができる。
【0055】
さらに、レンジフードファンを構成する上側整流メンバまたは下側整流メンバの周辺立上り部のコーナ部を滑らかに加工することができ、鋭いエッジ部がなく、機械的・物理的強度を向上させるとともに、清掃時に怪我をさせたりする損傷を未然にかつ確実に防止できる。
【0056】
さらに、整流板の表面を撥油性材料の被膜を施すことにより、清掃作業を効率よく短時間で行なうことができ、外観性を向上させ、商品性を高めることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a range hood fan provided with a blower inside, and more particularly, to a range hood fan that prevents condensation generated on the surface of a current plate.
[0002]
[Prior art]
In general, this type of range hood fan is configured as described in Japanese Patent No. 2508901 and Japanese Patent Application Laid-Open No. 2001-4181, and efficiently captures combustion gas, oily smoke / steam generated by cooking, and blower It is designed to be discharged outdoors.
[0003]
In recent years, electromagnetic cookers using induction heating heaters (Induction Heating heaters: IH heaters) have become widespread for the purpose of preventing fires from gas cookers in gas stoves and gas ranges.
[0004]
However, when an electromagnetic cooker is adopted as a cooking utensil, it has been found that condensation occurs on the current plate of the range hood fan, and the generated condensation gradually grows and drops into droplets.
[0005]
The problem of condensation on the range hood fan does not occur in the case of a gas stove. In the gas stove, the high-temperature combustion gas resulting from the combustion of the fuel gas is guided into the main body casing (hood main body) 3 by being guided by the rectifying plate 2 of the range hood fan 1 as shown in FIG. 10, and from the suction port 5 of the blower 4. It comes to be sucked. The combustion gas and steam sucked by the blower 4 are then blown from the blower 4 and discharged to the outside through the discharge port 6.
[0006]
At that time, the air guided to the current plate 2 of the range hood fan 1 and guided to the suction port 5 of the current plate 2 is heated by the combustion gas and warmed. For this reason, a large temperature difference does not occur between the surface temperature of the rectifying plate 2 and the back surface temperature on the back side, it is possible to effectively prevent the dew condensation on the rectifying plate 2 and no dew condensation problem occurs. It was.
[0007]
However, when an electromagnetic cooker provided with an induction heater is used, the ambient temperature hardly increases due to cooking by the electromagnetic cooker. For this reason, although the lower surface (front surface) of the rectifying plate 2 is warmed by the steam generated from the cooking pan, the air flowing on the back side of the rectifying plate 2 does not increase in temperature and is cold.
[0008]
[Problems to be solved by the invention]
When cooking with an electromagnetic cooker during the cooling operation of a winter or air conditioner, the rising steam generated from the pot or medicine can comes into contact with the surface (lower surface) of the rectifying plate 2 to cause condensation, and this condensation gradually grows. There was a problem of dropping into droplets. When the generated dew condensation drops as water droplets or the like, there is a problem that the kitchen is soiled and the cleanliness is impaired.
[0009]
The present invention has been made in consideration of the above-described circumstances, and provides a range hood fan capable of preventing condensation from occurring on the current plate surface in advance and effectively, and keeping the kitchen clean. With the goal.
[0010]
Another object of the present invention is to provide a range hood fan which is excellent in safety and can be easily and smoothly cleaned.
[0011]
Another object of the present invention is to provide a range hood fan in which the mounting structure of the rectifying plate is simplified to improve the merchantability, and the rectifying plate is attached and detached and the degree of freedom thereof is improved.
[0012]

The appearance shape is excellent, and the merchantability can be improved.
[0022]
The outer peripheral portions of the upper rectifying member 24 and the lower rectifying member 25 may be formed by bending. However, if both members 24 and 25 are formed by bending, they are formed at sharp corners at the outer corners, so care must be taken during cleaning. The upper rectifying member 24 and the lower rectifying member 25 are formed in a flat box shape having an opening on one surface by the rising portion 26.
[0023]
The upper rectifying member 24 and the lower rectifying member 25 having the peripheral rising portion 26 on the outer peripheral portion are formed to have substantially the same dimensions, and are integrally formed into a flat box shape by press-fitting and fitting. Both rectifying members 24 and 25 are firmly coupled by shrink fitting or the like that is fastening by friction bonding.

At that time, since the rectifying plate 14 is formed in a flat box shape and the heat insulating space layer 23 is formed inside, the metal fittings 28 and 29 can be fixed by screws to the upper rectifying member 24, and the mounting structure is simplified. Appearance shape is also good. The upper and lower surfaces of the rectifying plate 14 are formed in a substantially flat shape. A small hole (small hole) may be formed on the upper surface of the rectifying plate 14, specifically, the upper surface of the upper rectifying member 24. A plurality of small holes may be formed.
[0025]
Next, the operation of the range hood fan 10 will be described.
[0026]
When manufacturing the range hood fan 10, the rectifying plate 14 is detachably attached to the lower portion of the main body casing 11 as the hood main body using the hook metal fitting 28 and the hook metal fitting 29.
[0027]
The rectifying plate 14 includes at least a lower rectifying member 25 made of a non-combustible material, and is integrally flattened by combining the peripheral rising portions 26 and 26 of the lower rectifying member 25 and the upper rectifying member 24 so as to face each other. Configured to structure. The upper rectifying member 24 and the lower rectifying member 25 form a peripheral rising portion 26 by preferably drawing the outer peripheral portion, while the upper rectifying member 24 and the lower rectifying member 25 are coated with a resin coating of an oil repellent material. Applied. The resin coating may be applied to the outer surface of the rectifying plate 14 after the rectifying plate 14 is formed.
[0028]
Then, the upper rectifying member 24 and the lower rectifying member 25 are fitted by shrinkage fitting or the like with the rising portions 26 and 26 facing each other to assemble the flat box (disk) -shaped rectifying plate 14 integrally. The hook metal fitting 28 and the hook metal fitting 29 are attached to the upper flow straightening member 24 of the assembled current plate 14, and the current plate 14 is attached to the hood 13 at an interval using the hook metal fitting 28 and the metal hook metal 29. .
[0029]
By attaching the rectifying plate 14 to the hood 13, a suction flow path 17 extending from the periphery of the rectifying plate 14 to the suction port 16 of the blower 15 is formed. The suction port portion of the blower 15 is formed by a bell mouth 22 of the hood 13 so that the air flow guided to the suction flow path 17 is smoothly sucked into the blower 15 from below.
[0030]
In this way, the range hood fan 10 shown in FIGS. 1 and 2 is assembled and manufactured. The manufactured range hood fan 10 is installed in a kitchen such as each home or store.
[0031]
The installed range hood fan 10 is operated by energizing the blower 15 and driving the motor. By the operation of the blower 15, air is sucked into the suction flow path 17 from the periphery of the rectifying plate 14. The air flow sucked into the suction channel 17 is guided by the bell mouth 22 of the hood 13 and sucked into the blower 15 from the suction port 16. The air flow sucked into the blower 15 from below is blown outward in the radial direction, guided to the fan casing 20 and discharged to the outside through the discharge port 30.

The blower 15 that has been sucked in has its blowing direction changed, is guided by the fan casing 20, and is discharged from the outlet 30 to the outside.
[0033]
At that time, due to cooking by the electromagnetic cooker, water vapor or oily smoke generated by the induction heating action of the induction heater rises as an upward flow and comes into contact with the lower surface (surface) of the rectifying plate 14.
[0034]
However, even if the upward flow of water vapor or oil smoke collides with the surface of the rectifying plate 14 and contacts it, the rectifying plate 14 is formed with a flat heat insulating structure. It can be surely prevented. In this case, the rectifying plate 14 has the heat insulation space layer 23 formed therein, and is not affected by the temperature of the air discharged to the outside through the suction flow path 17.
[0035]
Further, even if the tempura oil is accidentally ignited during cooking by the electromagnetic cooker, the rectifying plate 14 is not adversely affected. Since the peripheral rising portions 26 and 26 of the upper rectifying member 24 and the lower rectifying member 25 are covered from the upper side with the hood 13 in the rectifying plate 14, it is effective that the joint portion of the peripheral rising portions 26 and 26 is exposed to the outside. The appearance shape can be improved. In addition, by forming the peripheral rising portions 26, 26 of the respective rectifying members 24, 25 by drawing, an R portion is formed in the peripheral corner portion. For this reason, even if a hand touches the corner part of the baffle plate 14 at the time of cleaning, it does not get injured, and the cleaning operation can be performed efficiently and smoothly, thereby improving safety.
[0036]
By coating the outer surface, at least the surface, of the rectifying plate 14 with an oil-repellent material such as silicon resin or fluororesin, an oil-repellent / water-repellent coating can be applied to the surface of the rectifying plate 14, and the workability of the cleaning work is improved. As a result, work can be simplified and streamlined.
[0037]
