Description

本発明は、ガスコンロ、電気コンロ、或いは電磁誘導加熱式クッキングヒータ（いわゆるＩＨクッキングヒータ）などの加熱調理器具による調理中に発生する廃ガス、油煙、湯煙（鍋などからの湯気）などの汚染空気の流れを整えるとともに吸込み捕獲効率を高めるために、フード部の下向き開口する捕獲空間に備えられる整流板、およびこの整流板を備えたレンジフードに関する。   The present invention relates to a flow of polluted air such as waste gas, oil smoke, hot smoke (steam from a pan, etc.) generated during cooking by a cooking device such as a gas stove, electric stove, or electromagnetic induction heating type cooking heater (so-called IH cooking heater). In order to improve the suction and capture efficiency, the present invention relates to a current plate provided in a capture space that opens downward in the hood portion, and a range hood provided with the current plate.

近年では、システムキッチンなどにマッチさせた統一感のあるデザイン性などが考慮されて薄型（平型）のレンジフードが注目されている。この薄型レンジフードは、下向きに開口する捕獲空間を有するフード部の上に、吸引力を捕獲空間に伝播させるとともに、捕獲空間に吸込み捕獲された汚染空気を屋外に排気する排気装置を設置してなる（例えば、特許文献１〜特許文献３などを参照）。
つまり、薄型レンジフードは、フード部の片側やその両側において取り付け配置されるキッチン棚などにマッチさせるなどのシステムキッチンとの統一感のあるデザイン性などの制約を受けずに、幅広く、フード部として斬新なデザインを実施することができるなどから、注目されている。 In recent years, thin (flat) range hoods are attracting attention in consideration of a unified design that matches system kitchens. This thin range hood has an exhaust device on the hood part that has a capture space that opens downward, and an exhaust device that propagates the suction force to the capture space and exhausts the contaminated air that has been sucked and captured into the capture space. (For example, see Patent Documents 1 to 3).
In other words, the thin range hood is widely used as a hood part without being restricted by the design with a sense of unity with the system kitchen such as matching the kitchen shelves attached and arranged on one side or both sides of the hood part. It attracts attention because it can implement innovative designs.

そして、薄型レンジフードでは、特許文献１〜特許文献３のそれぞれの図１に示されているように、フード部の下向きに開口する捕獲空間に、汚染空気の吸い込み捕獲効率（捕集効率）を高めるための整流板を備えている。
このように、フード部の捕獲空間に整流板を備えることで、整流板の周囲縁部と捕獲空間の開口周縁部との間に、汚染空気の吸込み流速を高める吸込み間隙（特許文献１では吸込み空間、特許文献２では吸気口と称している）を確保し、これにより、浅い捕獲空間でありながら、汚染空気の吸込み捕獲効率を高めるようにしている。
つまり、フード部の薄型化とともに捕獲空間の深さがより浅くなり、そのために、ガスコンロなどの加熱調理器の熱口（火口）や調理鍋から舞い上がり上昇に伴って広がる傾向にある汚染空気を捕獲空間で捕獲（捕集）できずにキッチン天井側などに取り逃がしてしまう。
この取り逃がしを抑えて捕獲空間での捕獲効率を高めるために、整流板の装着することによって捕獲空間の開口周縁部との間に吸込み流速の勢いを高める吸込み隙間を確保し、上昇に伴って広がる傾向にある汚染空気を取り逃がすことなく、吸込み隙間に勢い良く作用する吸込み流速によって捕獲空間に確実に吸込み捕獲するための改善が行われてきている。 And in thin range hoods, as shown in FIG. 1 of each of Patent Documents 1 to 3, the trapping space that opens downward in the hood part has a trapping efficiency (collection efficiency) for sucking and trapping contaminated air. A rectifying plate is provided to increase the height.
In this way, by providing the current plate in the capture space of the hood portion, a suction gap that increases the flow velocity of contaminated air between the peripheral edge of the current plate and the peripheral edge of the opening of the capture space (in Japanese Patent Application Laid-Open No. 2003-133867, suction). Space, which is referred to as an intake port in Patent Document 2), thereby improving the intake and capture efficiency of contaminated air while being a shallow capture space.
In other words, the depth of the capture space becomes shallower as the hood becomes thinner, and as a result, contaminated air that tends to spread as it rises from the hot mouth (crater) of a heating cooker such as a gas stove or cooking pan rises. It cannot be captured (collected) in the space, and it is lost to the kitchen ceiling.
In order to suppress this escape and increase the capture efficiency in the capture space, by installing a baffle plate, secure a suction gap that increases the momentum of the suction flow velocity between the opening peripheral edge of the capture space and spreads as it rises Improvements have been made to ensure that the trapping space is sucked and captured by the suction flow velocity that acts vigorously on the suction gap without escaping the contaminated air.

また、薄型レンジフードでは、特許文献１〜特許文献３に示されている。例えば、特許文献１に示されているように、キッチン壁への取り付けは、排気装置（送風機ユニット）の排気ボックスを、Ｌ形の吊り金具などを用いたネジ止めなどによって行われる。そのために、排気装置（排気ボックス）は、フード部の壁当接面部である後面部に略面一になるようにフード部の後側に位置し、フード部の天板（または捕獲空間の天面部）に開口されている吸気口（特許文献１の開口２１ａ）に連通されてフード部の上に設置される。つまり、薄型レンジフードでは、吊り金具などを用いたネジ止めによって排気装置がキッチン壁に定着固定され、排気装置にフード部が支持された状態で加熱調理器の略真上に位置して設置される。
そして、このように排気装置がフード部の後側に位置して設置されることで、特許文献１および特許文献２に示されているように、排気装置を目隠すようにフード部の天板の上からキッチン天井に至るように取り付けられる幕板（化粧板）をキッチン棚などの扉表面と略面一状態と成し得るようにしている。 Moreover, in the thin range hood, it is shown by patent document 1-patent document 3. For example, as shown in Patent Document 1, the attachment to the kitchen wall is performed by screwing the exhaust box of the exhaust device (blower unit) with an L-shaped hanging bracket or the like. For this purpose, the exhaust device (exhaust box) is positioned on the rear side of the hood portion so as to be substantially flush with the rear surface portion that is the wall contact surface portion of the hood portion, and the top plate of the hood portion (or the top of the capture space). It is communicated with an intake port (opening 21a of Patent Document 1) that is opened in the surface portion and is installed on the hood portion. In other words, in the thin range hood, the exhaust device is fixedly fixed to the kitchen wall by screwing using a hanging metal fitting, etc., and the hood portion is supported on the exhaust device and is positioned almost directly above the cooking device. The
And, as shown in Patent Document 1 and Patent Document 2, the top plate of the hood portion is hidden so that the exhaust device is located on the rear side of the hood portion as described above. A curtain board (decorative board) attached from the top to the kitchen ceiling can be made substantially flush with the door surface of a kitchen shelf or the like.

また、薄型レンジフードでは、調理者の手元や加熱調理器の熱口や調理鍋の鍋底などを照らす照明を、特許文献３に示されているように、捕獲空間の開口周縁部のうち、キッチン側（調理者側）に位置するフード部の前面部に沿う開口前辺縁部に備えて、調理者の手元や鍋底を効果的に照らすことができるようにしている。   In addition, in the thin range hood, as shown in Patent Document 3, the lighting that illuminates the hand of the cooker, the hot mouth of the cooking device, the bottom of the cooking pan, etc. In preparation for the front edge of the opening along the front portion of the hood portion located on the side (cooker side), the cooker's hand and pan bottom can be illuminated effectively.

特開２００６−１７０５３９号公報（段落番号００１１〜００１２、および図１参照）Japanese Patent Laying-Open No. 2006-170539 (see paragraph numbers 0011 to 0012 and FIG. 1) 特開２００７−１０７７５１号公報（段落番号００５４〜００５５、および図１参照）JP 2007-107751 (see paragraph numbers 0054 to 0055 and FIG. 1) 特開２００７−７８２２３号公報（段落番号００３３、および図１参照）JP 2007-78223 A (see paragraph number 0033 and FIG. 1)

ところで、特許文献３に示されているように、照明をフード部の前面部側に備えることで、調理者の手元や調理鍋の鍋底などを照らす上で有効である。つまり、ガスコンロなどの加熱調理器では、主に平面視で略四角形状を呈するトッププレートの前側２ヶ所と、後側中央１ヶ所に熱口（火口など）が備えられており、前側２ヶ所の熱口の使用頻度が高いものである。
そのために、前側２ヶ所の熱口を使用して中華鍋による野菜炒めや深底鍋によるビーフシチューなどの料理を作るときに、前側２ヶ所の熱口にかけられた鍋底、特に、深底鍋の鍋底まで確実に照らすことができる前側２ヶ所の熱口の略真上に位置するフード部の前面部側に位置させて照明を備えることが有効である。 By the way, as shown by patent document 3, it is effective in illuminating the hand of a cook, the pan bottom of a cooking pan, etc. by providing illumination in the front part side of a food | hood part. In other words, a cooking device such as a gas stove is equipped with two hot spots (such as a crater) at the front side of the top plate, which has a substantially rectangular shape in plan view, and at the center of the rear side. The hot mouth is frequently used.
For that purpose, when cooking dishes such as stir-fried vegetables in a Chinese wok or beef stew in a deep-bottom pan using the two hot-mouths on the front side, the bottom of the pan, especially the deep-bottom pan on the hot-mouth in the two front sides. It is effective to provide illumination by being positioned on the front side of the hood portion, which is positioned almost directly above the two hot ports on the front side, which can be surely illuminated to the bottom of the pan.

しかしながら、従来技術では、照明をフード部の前面部側に位置させて備えるために、特許文献３の図１に示されているように、前面部に沿う捕獲空間の開口前辺縁部の縁幅を、フード部の前面部から捕獲空間の内側に向けて縁方向全長（フード部の横幅全長）にわたり膨出させた幅広にしている。つまり、ランプなどの照明が取り付けられる照明ボックスを下向き開口の状態で内蔵させるための照明設置部を確保するために、従来では、開口前辺縁部の縁幅を、照明設置部に合わせて縁方向全長にわたり幅広にしている。
そのために、使用頻度が高く、それに伴い汚染空気の発生率（舞い上がり率）が高い前側２ヶ所の熱口の略真上に位置する捕獲空間の空間開口が、幅広形状の開口前辺縁部によって狭くなり、結果として、前側２ヶ所の熱口や調理鍋から舞い上がってくる汚染空気の一部をキッチン天井側に取り逃がしてしまうなどの問題を引き起こす原因となっていた。つまり、捕獲空間へと舞い上がってくる汚染空気の一部が、幅広形状の開口前辺縁部に突き当たり、吸込み隙間から捕獲空間に吸込み捕獲されることなく、キッチン天井側などへと拡散し取り逃がしてしまう問題（課題）が未だに残されており、その解決策が望まれている。 However, in the prior art, as shown in FIG. 1 of Patent Document 3, the edge of the front edge of the opening of the capture space along the front surface is provided in order to provide the illumination on the front surface side of the hood. The width is widened from the front surface portion of the hood portion toward the inside of the capture space over the entire length in the edge direction (the entire lateral width of the hood portion). In other words, conventionally, in order to secure a lighting installation part for incorporating a lighting box to which lighting such as a lamp is installed in a downward opening state, the edge width of the front edge of the opening is adjusted to match the lighting installation part. Wide in the entire direction.
For this reason, the space opening in the capture space, which is located just above the two hot ports at the front side, where the usage frequency is high and the rate of occurrence of polluted air (swelling rate) is high, is defined by the wide opening front edge. As a result, it became a cause of causing problems such as a part of the contaminated air rising from the hot mouths and cooking pots at the two front sides to the kitchen ceiling. In other words, part of the contaminated air that rises into the capture space hits the front edge of the wide opening, diffuses and escapes from the suction gap to the kitchen ceiling, etc. without being captured by the capture space. The problem (problem) which remains is still left, and the solution is desired.

そこで、本発明は、前記課題を解消するために創案されたものであり、薄型レンジフードであって、加熱調理器の前側２ヶ所の熱口にかけられた調理鍋の鍋底を効果的に照らすことができるフード部の前側に照明を備えた上で、前側２ヶ所の熱口や調理鍋から舞い上がってくる汚染空気を取り逃がすことなく確実に吸込み捕獲し得る開口形状を有する捕獲空間に備えられる整流板、およびこの整流板を備えたレンジフードを提供することにある。
また、排気装置の吸引力を、キッチン壁側に位置する捕獲空間の例えば、開口後辺縁部の一辺縁側を除く、残る三辺縁の開口前辺縁部および開口両辺縁部に沿う吸込み隙間へと有効に伝播させて、前側２ヶ所の熱口や調理鍋から舞い上がってくる汚染空気の捕獲効率をさらに向上させることが期待できる整流板を備えたレンジフードを提供することにある。 Therefore, the present invention was devised to solve the above-described problems, and is a thin range hood that effectively illuminates the bottom of a cooking pot that has been applied to two hot mouths on the front side of the heating cooker. Rectifying plate provided in a capture space with an opening shape that can reliably suck and capture the contaminated air rising from the hot mouth and cooking pan at the two locations on the front side of the hood that can perform And a range hood provided with the current plate.
In addition, the suction gap along the opening front edge part and the opening both edge parts of the remaining three edges, excluding, for example, one edge side of the opening rear edge part of the capture space located on the kitchen wall side. Another object is to provide a range hood equipped with a rectifying plate that can be effectively propagated and can be expected to further improve the trapping efficiency of polluted air that rises from two hot ports and cooking pans on the front side.

前記課題を解決するために、本発明の整流板では、フード部の捕獲空間の開口周縁部の少なくとも一部に、前記捕獲空間の内側に向けて縁方向全長にわたらないように膨出させた膨出部を設けて、この膨出部の両側または片側に備えられる拡張空間を有する前記捕獲空間に取り付け配置されて、前記開口周縁部との間に吸込み間隙を確保する整流板であって、整流板本体は、前記膨出部に応じて対向する整流板の縁全長にわたらない窪み部を備え、この窪み部は、前記膨出部との間に前記吸込み間隙を確保する底面視形状にて前記整流板本体の周囲縁部に形成され、前記膨出部の両側または片側に備えられる拡張空間を有する部分において、前記吸込間隙の幅が他の部分より広いことを特徴とする。 In order to solve the above-mentioned problem, in the current plate of the present invention, at least a part of the opening peripheral edge of the capture space of the hood portion is bulged so as not to extend over the entire length in the edge direction toward the inside of the capture space. A rectifying plate that is provided with a bulging portion, is attached to the capture space having an expansion space provided on both sides or one side of the bulging portion, and secures a suction gap between the opening peripheral portion, The rectifying plate body includes a dent that does not extend over the entire length of the rectifying plate facing the bulging portion, and the dent has a bottom view shape that secures the suction gap between the bulging portion and the bulging portion. In the portion having the expansion space formed on the peripheral edge portion of the rectifying plate body and provided on both sides or one side of the bulging portion, the suction gap is wider than the other portion .

ここで、前記窪み部は、底面視で略四角形状を呈する前記整流板本体の周囲四辺縁部のうち、その一辺縁部を、前記膨出部の膨出形状に沿わせ、かつ、前記捕獲空間の前記拡張空間側に向けて延設させることで形成される構成を採用することが好適なものとなる。   Here, the hollow portion has a one-side edge portion along a bulging shape of the bulging portion among the four peripheral edge portions of the rectifying plate main body that has a substantially square shape in a bottom view, and the capture It is preferable to adopt a configuration formed by extending the space toward the expansion space.

このような構成の整流板によれば、捕獲空間の開口周縁部の少なくとも一部に膨出部を備え、この膨出部の両側または片側に捕獲空間の拡張空間を有する開口形状の捕獲空間に、整流板本体を取り付けることで、膨出部との間に吸込み間隙を確保し、しかも、拡張空間における開口周縁部との間に吸込み隙間を確保することができる。
例えば、キッチン側に位置するフード部の前面部に沿う捕獲空間の開口周縁部の一部である開口前辺縁部の縁方向の中央部位に、照明設置部として利用される膨出部を備えてなる捕獲空間の開口形状において、窪み部によって膨出部との間に吸込み間隙を確保し、膨出部の膨出基部から連なる両側の拡張空間における開口前辺縁部との間においても吸込み間隙を確保するように、捕獲空間に整流板本体を取り付けることができる。
これにより、例えば、使用頻度が高く、キッチン側に位置する加熱調理器の前側２ヶ所の熱口や調理鍋などから舞い上がる汚染空気を、膨出部の膨出周面との間に確保される吸込み隙間と、前側２ヶ所の熱口の略真上に位置して開口する両側の拡張空間との間に確保される吸込み隙間に発生する吸込み作用によってキッチン天井側に取り逃がすことなく、確実に吸込み捕獲することが期待される。 According to the rectifying plate having such a configuration, an opening-shaped capture space having a bulging portion at least at a part of the opening peripheral edge of the capturing space and having an expansion space of the capturing space on both sides or one side of the bulging portion. By attaching the current plate main body, a suction gap can be secured between the bulging portion and a suction gap can be secured between the opening peripheral edge portion in the expansion space.
For example, a bulging part used as a lighting installation part is provided at the central part in the edge direction of the opening front edge part which is a part of the opening peripheral part of the capture space along the front part of the hood part located on the kitchen side. In the shape of the opening of the capture space, the suction gap is secured between the bulge and the bulge, and the gap between the bulge and the front edge of the opening in the expansion space on both sides of the bulge A current plate main body can be attached to the capture space so as to ensure a gap.
Thereby, for example, the use frequency is high, and the polluted air that rises from two hot mouths and cooking pans on the front side of the cooking device located on the kitchen side is secured between the bulging peripheral surface of the bulging portion. Suction without failing to escape to the kitchen ceiling due to the suction action generated in the suction gap that is secured between the suction gap and the expansion spaces on both sides that are located just above the front two hot ports. Expected to capture.

また、本発明のレンジフードでは、捕獲空間を有するフード部と、前記捕獲空間の天面部に開口されている吸気口に連通させて前記フード部の上に設置される排気装置と、前記捕獲空間に取り付け配置されて、該捕獲空間の開口周縁部との間に吸込み間隙を確保する整流板と、を備えているレンジフードであって、前記捕獲空間の開口周縁部の少なくも一部に、前記捕獲空間の内側に向けて縁方向全長にわたらないように膨出させた膨出部を備えて、この膨出部の両側または片側に前記捕獲空間の拡張空間を備え、かつ、前記膨出部との間に前記吸込み間隙を確保する底面視形状の整流板本体は、前記膨出部に応じて対向する整流板の縁全長にわたらない窪み部を前記整流板の周囲縁部に備え、前記膨出部の両側または片側に備えられる拡張空間を有する部分において、前記吸込間隙の幅が他の部分より広いことを特徴とする。 Further, in the range hood of the present invention, a hood portion having a capture space, an exhaust device installed on the hood portion in communication with an intake opening opened in a top surface portion of the capture space, and the capture space is attached positioned on, the suction and rectifying plate to secure the gap, a range hood that is provided with a least a portion of the opening edge of the capturing space between the opening peripheral edge portion of said capturing space, A bulging portion that bulges toward the inside of the capture space so as not to extend over the entire length in the edge direction, and includes an expansion space of the capture space on both sides or one side of the bulge portion, and the bulge The rectifying plate main body in a bottom view shape that secures the suction gap between the portion includes a hollow portion that does not extend over the entire length of the rectifying plate facing according to the bulging portion at the peripheral edge of the rectifying plate, Expansion provided on both sides or one side of the bulge In the portion having between the width of the suction gap is equal to or wider than other portions.

ここで、前記膨出部は、底面視で略四角形状を呈する前記捕獲空間の前記開口周縁部の一部を除いて、該開口周縁部の縁幅を幅狭にすることで前記開口周縁部の前記一部に形成され、前記窪み部は、前記開口周縁部との間に、前記吸込み間隙を確保する程度の大きさに形成されて底面視で略四角形状を呈する前記整流板の周囲縁部のうち、その一辺縁部を、前記膨出部の膨出形状に沿わせ、かつ、前記捕獲空間の前記拡張空間側に向けて延設させることで前記一辺縁部に形成される構成を採用することが好適なものとなる。   Here, the bulging portion is formed by narrowing an edge width of the opening peripheral portion except for a part of the opening peripheral portion of the capture space that has a substantially square shape in a bottom view. The dent is formed in the part of the rectifying plate and is formed in a size that is sufficient to secure the suction gap between the opening and the peripheral edge of the opening, and has a substantially rectangular shape in bottom view. Among the portions, the one edge portion is formed along the bulging shape of the bulging portion and extended toward the expansion space side of the capture space to form the one edge portion. It is suitable to adopt.

また、前記吸気口が、底面視で前記フード部の中央部位よりもキッチン壁に接する該フード部の壁当接面部側寄りに位置して開口され、前記吸込み間隙が、前記壁当接面部側に位置する前記開口周縁部との間では狭く、前記壁当接部側以外の他の開口周縁部との間では広く確保されていることが好適なものとなる。
さらに、前記膨出部は、前記フード部に備えられるオイルパネルに一体に形成され、かつ、前記開口周縁部に略平面的に連なる膨出面の面周囲から前記捕獲空間の空間底および前記拡張空間の空間底に至る膨出周面形状が流線形に形成されていることが好適なものとなり、この膨出部が、照明設置部であり、照明設置部が、キッチン側に位置するフード部の前面部に沿う前記開口周縁部の縁方向の中央部位に備えられている。つまり、加熱調理器の前側２ヶ所の熱口間における中央部の略真上に位置する開口周縁部に前記照明設置部が備えられ、この照明設置部の両側には側２ヶ所の熱口の略真上に位置する前記捕獲空間の拡張空間が備えられる。 In addition, the intake port is opened at a position closer to the wall contact surface portion side of the hood portion that is in contact with the kitchen wall than the central portion of the hood portion in a bottom view, and the suction gap is formed on the wall contact surface portion side. It is preferable that the gap is narrow between the opening peripheral edge located at the center and the other opening peripheral edge other than the wall contact portion side.
Further, the bulging portion is formed integrally with an oil panel provided in the hood portion, and from the periphery of the bulging surface that is substantially planarly connected to the peripheral edge of the opening, the space bottom of the capture space and the expansion space It is preferable that the bulging peripheral surface shape reaching the bottom of the space is streamlined, and this bulging part is a lighting installation part, and the lighting installation part is a hood part located on the kitchen side. It is provided in the center part of the edge direction of the said opening peripheral part along a front part. In other words, the lighting installation portion is provided at the opening peripheral edge located substantially directly above the central portion between the two hot ports on the front side of the heating cooker, and two hot ports on the side are provided on both sides of the lighting installation portion. An expansion space of the capture space located substantially directly above is provided.

このような構成によれば、排気装置の運転により通気口から捕獲空間に伝播される吸引力によって、捕獲空間の内側に膨出する膨出部である照明設置部の膨出周面と整流板の窪み部との間、そして、捕獲空間の拡張空間の開口周縁部と整流板の周囲縁部との間に確保される吸込み隙間に効果的に勢いの良い吸込み作用が発生する。
これにより、加熱調理器の前側２ヶ所の熱口や調理鍋から舞い上がってくる汚染空気を、照明設置部の膨出周面との間の吸込み隙間から吸込み捕獲し、そして、前側２ヶ所の略真上に位置する両側の拡張空間の開口周縁部との間の隙間から拡張空間に吸込み捕獲することができる。 According to such a configuration, the bulging peripheral surface of the lighting installation portion and the rectifying plate which are bulging portions that bulge inside the capture space by the suction force transmitted from the vent to the capture space by the operation of the exhaust device The suction action is effectively generated in the suction gap that is secured between the hollow portion of the capture space and between the opening peripheral edge portion of the expansion space of the capture space and the peripheral edge portion of the rectifying plate.
As a result, the contaminated air that rises from the two hot mouths and cooking pans on the front side of the heating cooker is sucked and captured from the suction gap between the bulging peripheral surface of the lighting installation section, and the two front side abbreviations. The expansion space can be sucked and captured from the gap between the opening peripheral edge portions of the expansion space on both sides located directly above.

また、キッチン壁に接するフード部の壁当接面部側に位置する開口周縁部との間では吸込み隙間を狭く、壁当接部側以外の他の開口周縁部との間では吸込み隙間が広く確保される。例えば、キッチン壁に接するフード部の後側の吸込み隙間は狭く、キッチン側、そしてキッチン棚側のフード部の前側および左右両側の吸込み隙間は広くしている。
これにより、吸気口から捕獲空間に伝播された吸引力は、狭く設定されているフード部の後側の吸込み隙間側よりも、広く設定されているフード部の前側および左右両側の吸込み隙間により多く伝播される。
つまり、狭く設定されている吸込み隙間は気流抵抗（気流摩擦）が大きく、広く設定されている吸込み隙間は気流抵抗が小さいために、吸気口からの吸引力の伝播は、気流抵抗が少ないフード部の前側の吸込み隙間と左右両側の吸込み隙間に多めに行われ、この前側の吸込み隙間と左右両側の吸込み隙間に勢い良く発生する吸込み作用によって加熱調理器の前側２ヶ所の熱口や調理鍋から舞い上がり上昇に伴って広がる汚染空気を取り逃がすことなく、確実に捕獲空間へと吸込み捕獲することができる。 In addition, the suction gap is narrow between the hood part in contact with the kitchen wall and the opening peripheral part located on the wall contact surface part side, and a wide suction gap is secured between the opening peripheral part other than the wall contact part side. Is done. For example, the suction gap on the rear side of the hood part in contact with the kitchen wall is narrow, and the suction gaps on the kitchen side and the front and left and right sides of the hood part on the kitchen shelf side are wide.
As a result, the suction force propagated from the intake port to the capture space is larger in the suction gaps on the front side and the left and right sides of the wide hood part than in the suction gap side on the rear side of the hood part that is set narrowly. Propagated.
In other words, the narrow suction gap has a large airflow resistance (airflow friction), and the wide suction gap has a low airflow resistance. The front suction gap and the left and right suction gaps are increased, and the suction action generated vigorously in the front suction gap and the left and right suction gaps from the two hot mouths and cooking pans on the front side of the heating cooker. Without taking away the polluted air that spreads as it rises, it can be reliably sucked and captured into the capture space.

また、膨出部がオイルパネルに一体に備えられていることで、例えば、膨出部を照明設置部とした場合、照明ボックスを隠すための目隠し化粧部として照明設置部が役目を成す。これにより、別途の目隠し部材などを必要とせずに、照明を設置することができる。
また、オイルパネルをフード部に取り付けることで、照明設置部をフード部の前面部に沿う開口周縁部の縁方向の中央部位に備えることができることで、調理者の手元や加熱調理器の熱口にかけられた調理鍋の鍋底などを、フード部の前側に備えられる照明によって万遍に照らすことができる。
また、膨出部の膨出周面形状が捕獲空間および拡張空間の空間底に向けて流線形に形成されていることで、気流抵抗を受けることなく、円滑な流れにて汚染空気は捕獲空間および拡張空間に吸込み捕獲される。 In addition, since the bulging part is integrally provided in the oil panel, for example, when the bulging part is used as a lighting installation part, the lighting installation part serves as a blindfold makeup part for hiding the lighting box. Thereby, illumination can be installed without requiring a separate blindfold member or the like.
In addition, by attaching the oil panel to the hood part, the lighting installation part can be provided at the center part in the edge direction of the opening peripheral part along the front part of the hood part, so that the cooker's hand and the hot mouth of the heating cooker The bottom of the cooking pot that is hung on the top of the hood can be illuminated uniformly by illumination provided on the front side of the hood.
In addition, the bulging surface shape of the bulging part is streamlined toward the bottom of the capture space and expansion space, so that the contaminated air can be captured in a smooth flow without receiving airflow resistance. And it is sucked and captured in the expansion space.

本発明の整流板は以上のように構成されていることで、例えば、キッチン側に位置するフード部の前面部に沿う捕獲空間の開口周縁部の一部である開口前辺縁部の縁方向の中央部位に、照明設置部として利用される膨出部を備えてなる捕獲空間の開口形状において、捕獲空間に窪み部を備える特殊な整流板本体を取り付けることで、窪み部によって膨出部との間に吸込み間隙を確保し、膨出部の膨出基部から連なる両側の拡張空間における開口前辺縁部との間においても吸込み間隙を確保することができる。
これにより、キッチン側に位置する加熱調理器の前側２ヶ所の熱口や調理鍋などから舞い上がる汚染空気を、膨出部の膨出周面との間に確保される吸込み隙間と、前側２ヶ所の熱口の略真上に位置して開口する両側の拡張空間との間に確保される吸込み隙間に発生する吸込み作用によってキッチン天井側に取り逃がすことなく、確実に吸込み捕獲することができる。 The current plate of the present invention is configured as described above, for example, the edge direction of the opening front edge that is a part of the opening peripheral edge of the capture space along the front surface of the hood located on the kitchen side In the opening shape of the capture space provided with a bulging part used as a lighting installation part at the central part of the A suction gap can be ensured between the two and the front opening edge in the expansion space on both sides continuous from the bulging base portion of the bulging portion.
As a result, the suction gap that is secured between the swollen peripheral surface of the bulging part and the front two places of the contaminated air that rises from the hot mouth and cooking pan at the front two places of the cooking device located on the kitchen side The suction action that is generated in the suction gap secured between the open spaces located on both sides of the opening and located almost directly above the hot mouth of the kitchen can surely suck and capture without being released to the kitchen ceiling.

また、本発明のレンジフードは以上のように構成されていることで、加熱調理器の前側２ヶ所の熱口の略真上に位置している捕獲空間の両側の拡張空間において、該拡張空間の開口周縁部と整流板の周囲縁部との間に確保される吸込み隙間に勢い良く発生する吸込み流速によって、加熱調理器の前側２ヶ所の熱口や調理鍋から舞いがってくる汚染空気を取り逃がすことなく、確実にキャッチして吸込み捕獲することができる。
つまり、両側の拡張空間は前側２ヶ所の熱口の略真上に位置して開口され、しかも、吸気口からより多くの吸引力が伝播されて整流板の周囲縁部（延長縁部）との間に確保される吸込み隙間に勢い良く吸込み流速が作用するなどから、前側２ヶ所の熱口や調理鍋から舞い上がってくる汚染空気を取り逃がすことなく、両側の拡張空間にて確実にキャッチして吸込み捕獲することができる。 In addition, the range hood of the present invention is configured as described above, so that in the expansion space on both sides of the capture space, which is positioned substantially directly above the two hot ports on the front side of the cooking device, the expansion space Contaminated air that flies from the two hot mouths and the cooking pan at the front side of the heating cooker due to the suction flow velocity generated in the suction gap secured between the peripheral edge of the opening and the peripheral edge of the current plate It is possible to catch and suck and capture without missing.
In other words, the expansion space on both sides is opened and positioned almost directly above the two heat ports on the front side, and more suction force is propagated from the air intake port to the peripheral edge (extension edge) of the current plate Since the suction flow velocity vigorously acts on the suction gap secured between the two, the air can be caught securely in the expansion space on both sides without letting out the contaminated air that has risen from the two hot ports and the cooking pan. Inhalation can be captured.

また、例えば、キッチン壁に接するフード部の後側の吸込み隙間は狭く、キッチン側、そしてキッチン棚側のフード部の前側および左右両側の吸込み隙間は広く確保されていることで、吸気口から捕獲空間に伝播される排気装置の吸引力は、狭く設定されているフード部の後側の吸込み隙間側よりも、広く設定されているフード部の前側および左右両側の吸込み隙間により多く伝播されることができる。
これにより、フード部の前側および左右両側の吸込み隙間における吸込み流速の勢いをより一層高めることができるために、加熱調理器の前側２ヶ所の熱口や調理鍋から舞い上がってくる汚染空気の捕獲効率をさらに向上させることが期待できる。 In addition, for example, the suction gap on the rear side of the hood that touches the kitchen wall is narrow, and the suction gap on the kitchen side and on the front and left and right sides of the hood on the kitchen shelf side is secured widely so that it can be captured from the intake port. The suction force of the exhaust system that is propagated to the space is more propagated to the suction gaps on the front side and the left and right sides of the hood part that are set wider than the suction gap side on the rear side of the hood part that is set narrower Can do.
As a result, the momentum of the suction flow velocity in the suction gaps on the front side and the left and right sides of the hood part can be further increased, so that the trapping efficiency of the contaminated air that rises from the hot mouths and cooking pans at the two front sides of the cooking device Can be expected to improve further.

また、膨出部を、照明を取り付ける照明設置部として使用した場合、照明設置部が照明ボックスを隠すための目隠し化粧部として役目を成すことで、照明の設置コストを低く抑えることができる。   In addition, when the bulging portion is used as an illumination installation portion for attaching illumination, the illumination installation portion serves as a blindfold makeup portion for concealing the illumination box, so that the installation cost of illumination can be kept low.

また、照明設置部の膨出周面形状が捕獲空間および拡張空間の空間底に向けて流線形に形成されていることで、汚染空気は気流抵抗を受けることなく、円滑な流れにて捕獲空間および拡張空間に吸込み捕獲される。これにより、加熱調理器の前側２ヶ所の熱口や調理鍋から舞いがってくる汚染空気をキッチン天井側に取り逃がすことなく、より確実に吸込み捕獲し、その捕獲効率を向上させることができる。   In addition, the bulging peripheral surface shape of the lighting installation part is streamlined toward the bottom of the capture space and the expansion space, so that the contaminated air is not subjected to airflow resistance and the capture space is smoothly flowed. And it is sucked and captured in the expansion space. As a result, it is possible to more reliably suck and capture the contaminated air flying from the hot mouths and cooking pots at the two front sides of the heating cooker to the kitchen ceiling side, and improve the capture efficiency.

The extended space portions M1 on both sides are located substantially directly above the two hot ports b on the front side of the heating cooker B. In this way, the contaminated air G that tends to spread from the hot mouth b and the cooking pan C at the two front sides and spread as it rises is surely sucked and captured by the expansion space M1 on both sides without being released to the kitchen ceiling K2 side or the like. Can do.

また、捕獲空間Ｍは、天面部１３（オイルパネル１７）に吸気口１２を備えている。この吸気口１２は、図１および図２に示すように、底面視で天面部１３の中央部位よりもフード部１の後面部１ｃ側寄りにおいて開口されている。つまり、フード部１の天板７に開口されている連絡口１０の開口軸芯上に略位置して天面部１３に開口されている。
これにより、捕獲空間Ｍの空気口１２が、前記したように、連絡口１０を挿通させて取り付けられる接続口部材１４によって排気装置２のファンケーシング２ｂの吸引口１１と直結されるようにしている。 Further, the capture space M includes an air inlet 12 in the top surface portion 13 (oil panel 17). As shown in FIGS. 1 and 2, the air inlet 12 is opened closer to the rear surface portion 1 c side of the hood portion 1 than the central portion of the top surface portion 13 in a bottom view. That is, the top surface portion 13 is opened substantially at the opening axis of the communication port 10 opened in the top plate 7 of the hood portion 1.
Thereby, as described above, the air port 12 of the capture space M is directly connected to the suction port 11 of the fan casing 2b of the exhaust device 2 by the connection port member 14 that is inserted through the connection port 10 and attached. .

A depression 4a is provided at one edge corresponding to the illuminating lighting installation 9.

≪窪み部の構成≫
窪み部４ａは、照明設置部９が備えられている捕獲空間Ｍの開口前辺縁部３ａとの間で吸込み隙間Ｓ１を確保する整流板４の一辺縁部において、照明設置部９の膨出形状（膨出周面）に沿わせ、かつ、捕獲空間Ｍの両側の拡張空間Ｍ１側に向けてそれぞれ延設させることで、図７に示すように、底面視で略四角形状を呈する整流板４の一辺縁部の縁方向の略中央部位において、底面視形状が略コの字形状（台形形状）に形成される。
つまり、窪み部４ａを挟む整流板４の一辺縁部の両側には、図２に示すように、整流板４の左右の両側辺縁部に連なるように延設された両側の拡張空間Ｍ１における開口前辺縁部３ａとの間で吸込み空隙Ｓ１を確保する延設縁部４ｂが備えられている。
これにより、両側の拡張空間Ｍ１における汚染空気Ｇの吸込み流速を確実に高めて、加熱調理器Ｂの前側２ヶ所の熱口ｂや調理鍋Ｃから舞い上がってくる多くの汚染空気Ｇを、キッチン天井Ｋ２側へと取り逃がすことなく、拡張空間Ｍ１（捕獲空間Ｍ）へと確実に吸込み捕獲し、屋外に排気することができる。 ≪Configuration of the hollow part≫
The recessed portion 4a bulges out the lighting installation portion 9 at one edge portion of the rectifying plate 4 that secures the suction gap S1 between the opening front edge portion 3a of the capture space M in which the lighting installation portion 9 is provided. As shown in FIG. 7, the rectifying plate has a substantially rectangular shape when viewed from the bottom by extending along the shape (bulging circumferential surface) and extending toward the expansion space M1 on both sides of the capture space M. 4 is formed in a substantially U-shape (trapezoidal shape) in a substantially central portion in the edge direction of one edge portion.
That is, on both sides of one side edge portion of the rectifying plate 4 sandwiching the recess 4a, as shown in FIG. 2, in both sides of the expansion space M1 extending so as to be continuous with the left and right side edge portions of the rectifying plate 4 An extended edge 4b that secures a suction gap S1 with the front edge 3a of the opening is provided.

The air can be reliably sucked and captured into the expansion space M1 (capturing space M) and discharged to the outside without being lost to the K2 side.

そして、このように一辺縁部の中央部位に窪み部４ａを備え、その両側に延長縁部４ｂを備えた整流板４は、図１および図２に示すように、フード部１の後側（キッチン壁Ｋ１側）に確保される吸込み隙間Ｓ２の間隔Ｌ１が狭く、フード部１の前側（キッチンＫ側）および左右両側（図示省略のキッチン棚側）に確保される吸込み隙間Ｓ１，Ｓ３の間隔Ｌ１，Ｌ３が広くなるように捕獲空間Ｍに取り付ける。
これにより、接続口部材１４を通して吸気口１２から捕獲空間Ｍに伝播される排気装置２からの吸引力は、フード部１の後側の吸込み隙間Ｓ２に比べて、フード部１の前側と左右両側の吸込み隙間Ｓ１，Ｓ３に多く伝播される。
つまり、後側の吸込み隙間Ｓ２は、図２に示すように、吸引力が伝播される吸気口１２から近いものの、前側の吸込み隙間Ｓ１の間隔Ｌ２と左右両側の吸込み隙間Ｓ３の間隔Ｌ３に比べて間隔Ｌ１が狭く設定されているために、気流抵抗（気流摩擦）が大きくなる。一方、前側の吸込み隙間Ｓ１と左右両側の吸込み隙間Ｓ３の間隔Ｌ１，Ｌ３は広く設定されているために、気流抵抗は小さい。これにより、吸気口１２からの吸引力の伝播は、気流抵抗が少ない前側の吸込み隙間Ｓ１と左右両側の吸込み隙間Ｓ２に多めに行われることになる。 As shown in FIGS. 1 and 2, the rectifying plate 4 provided with the recess 4a in the central portion of the one side edge and the extended edge 4b on both sides of the ridge part 4 as shown in FIGS. The gap L1 between the suction gaps S2 secured on the kitchen wall K1 side is narrow, and the gaps between the suction gaps S1 and S3 secured on the front side (kitchen K side) and the left and right sides (kitchen shelf side not shown) of the hood 1 It attaches to the capture space M so that L1 and L3 become wide.
As a result, the suction force from the exhaust device 2 transmitted from the intake port 12 to the capture space M through the connection port member 14 is larger than the suction gap S2 on the rear side of the hood portion 1 and on both the left and right sides of the hood portion 1. It is often transmitted to the suction gaps S1 and S3.
That is, as shown in FIG. 2, the rear suction gap S2 is close to the intake port 12 through which the suction force is propagated, but compared to the interval L2 between the front suction gap S1 and the interval L3 between the left and right suction gaps S3. Since the interval L1 is set narrow, the airflow resistance (airflow friction) increases. On the other hand, since the gaps L1 and L3 between the front suction gap S1 and the left and right suction gaps S3 are set wide, the airflow resistance is small. As a result, the propagation of the suction force from the intake port 12 is performed more in the front suction gap S1 and the left and right suction gaps S2 with less airflow resistance.

ちなみに、整流板４は、図１に示すように、フード部１の後側における捕獲空間Ｍに備えられている左右の支持部材２６によって、整流板４の後側が回動自在で、かつ、適宜係脱自在に支持され、フード部１の前側における捕獲空間Ｍに備えられている左右の係脱部材２７によって、整流板４の前側が係脱自在に支持されて捕獲空間Ｍに、前記した形態にて取り付け配置されるようになっている。
これにより、整流板４の上に溜まった油脂分や捕獲空間Ｍの天面部１３（オイルパネル１７の内面）に付着している油脂分などの汚れを拭き取ったり、排気装置２の排気ファン２ｄをファンケーシング２ｂ内から取り外してシンクなどにおいて洗浄するときなどにおいて、図４に示すように、整流板８をフード部１の後側（キッチン壁Ｋ１側）に下向きに回動させて捕獲空間Ｍを開くことができるようにしている。また、後側の支持部材２６に対する係止（掛止）状態を解除することで、整流板４をシンクなどにおいて洗浄することができるようにしている。 Incidentally, as shown in FIG. 1, the rectifying plate 4 is configured such that the rear side of the rectifying plate 4 is freely rotatable by the left and right support members 26 provided in the capture space M on the rear side of the hood portion 1. The form described above is supported in the capture space M by the left and right engagement / disengagement members 27 that are supported in a detachable manner and are provided in the capture space M on the front side of the hood portion 1. It comes to be mounted and arranged.
As a result, the oil and fat collected on the current plate 4 and the oil and fat attached to the top surface 13 (the inner surface of the oil panel 17) of the capture space M are wiped off, or the exhaust fan 2d of the exhaust device 2 is removed. When the fan casing 2b is removed from the inside of the fan casing 2b and washed in a sink or the like, as shown in FIG. 4, the rectifying plate 8 is rotated downward to the rear side (kitchen wall K1 side) of the hood portion 1 so that the capture space M is formed. It can be opened. Further, the rectifying plate 4 can be cleaned in a sink or the like by releasing the locked (hanging) state with respect to the support member 26 on the rear side.

≪排気装置の構成≫
ここでは、図１および図２を適宜参照しながら説明する。
排気装置２は、図１に示すように、フード部１の天板７上に横置きにて設置される。この排気装置２は、天板７の上にネジ止めなどによって取り付けられる排気ボックス２ａと、この排気ボックス２ａ内に内設されるファンケーシング２ｂと、このファンケーシング２ｂ内に、ファンモータ２ｃに軸支されて同軸上に収容される排気ファン（遠心ファンや多翼ファンなど）２ｄとを備えて構成されている。 ≪Exhaust system configuration≫
Here, description will be made with reference to FIGS. 1 and 2 as appropriate.
As shown in FIG. 1, the exhaust device 2 is installed horizontally on the top plate 7 of the hood portion 1. The exhaust device 2 includes an exhaust box 2a attached to the top plate 7 by screws or the like, a fan casing 2b installed in the exhaust box 2a, and a fan motor 2c in the fan casing 2b. An exhaust fan (such as a centrifugal fan or a multi-blade fan) 2d that is supported and accommodated on the same axis is provided.

そして、排気ボックス２ａ内に横置き（水平置き）に内設されるボリュート形状のファンケーシング２ｂにラッパ形状のベルマウスによって形成される吸引口１１と捕獲空間Ｍの天面部１３に開口されている吸気口１２とが、フード部１の天板７に開口されている連絡口１０を上下に挿通する接続口部材１４によって直結されることで、排気ファン２ｄの回転運転による吸引力が吸気口１２から捕獲空間Ｍに伝播され、各吸込み隙間Ｓ１〜Ｓ３に勢い良く吸込み流速が発生するようになっている。
ちなみに、接続口部材１４は、プレスなどによる絞り曲げ加工によって筒形状に形成されて、上端開口側が吸引口１１に、下端開口側が吸気口１２にそれぞれ接続されるようになっている。 Then, a volute fan casing 2b installed horizontally (horizontal) in the exhaust box 2a is opened to a suction port 11 formed by a trumpet bell mouth and a top surface portion 13 of the capture space M. The suction port 12 is directly connected by the connection port member 14 that vertically passes through the communication port 10 opened in the top plate 7 of the hood portion 1, so that the suction force due to the rotational operation of the exhaust fan 2 d is generated by the suction port 12. From the air to the capture space M, and a suction flow velocity is generated vigorously in each of the suction gaps S1 to S3.
Incidentally, the connection port member 14 is formed into a cylindrical shape by drawing bending using a press or the like, and the upper end opening side is connected to the suction port 11 and the lower end opening side is connected to the intake port 12.

次に、以上のように構成されている本実施形態に係る整流板（整流板本体）４およびこの整流板４を備えたレンジフードＡの作用について簡単に説明する。ここでは、図１および図２を適宜参照しながら説明する。
排気装置２の排気ファン２ｄが操作スイッチ１５による強弱３段階のいずれかによって回転運転すると、ファンケーシング２ｂの吸引口１１から接続口部材１４を通して吸気口１２から捕獲空間Ｍに吸引力が伝播される。このとき、捕獲空間Ｍに伝播された吸引力は、間隔Ｌ１が狭く設定されているフード部１の後側の吸込み隙間Ｓ２側よりも、間隔Ｌ２，Ｌ３が広く設定されているフード部１の前側および左右両側の吸込み隙間Ｓ１，Ｓ３側により多く伝播される。
これにより、加熱調理器Ｂからフード部１に至る全高にわたりキッチン壁Ｋ１が存在するフード部１の後側に比べて、汚染空気Ｇを取り逃がし易いフード部１の前側および左右両側の吸込み隙間Ｓ１，Ｓ３は、吸気口１２からより多く伝播されてくる吸引力によって勢い良く吸込み流速が作用するために、加熱調理器Ｂの熱口ｂや調理鍋Ｃから舞い上がり上昇に伴って広がる汚染空気Ｇを取り逃がすことなく、確実に捕獲空間Ｍへと吸込み捕獲し、屋外に排気することができる。 Next, the operation of the rectifying plate (rectifying plate body) 4 according to the present embodiment configured as described above and the range hood A including the rectifying plate 4 will be briefly described. Here, description will be made with reference to FIGS. 1 and 2 as appropriate.
When the exhaust fan 2d of the exhaust device 2 is rotated by one of three levels of strength by the operation switch 15, suction force is transmitted from the suction port 11 of the fan casing 2b through the connection port member 14 to the capture space M from the suction port 12. . At this time, the suction force propagated to the capture space M is that of the hood part 1 with the intervals L2 and L3 set wider than the suction gap S2 side on the rear side of the hood part 1 with the interval L1 set narrower. More propagation is performed on the suction gaps S1 and S3 sides on the front side and the left and right sides.
Thereby, compared with the rear side of the hood part 1 where the kitchen wall K1 exists over the entire height from the heating cooker B to the hood part 1, the suction gaps S1, on the front side and the left and right sides of the hood part 1 from which the contaminated air G is easily removed. In S3, since the suction flow velocity acts vigorously due to the suction force propagated more from the intake port 12, the polluted air G that spreads as it rises from the hot port b and the cooking pan C of the heating cooker B is released. Without being sucked and captured into the capture space M and exhausted outdoors.

また、図１に一点鎖線で示す矢印のように、整流板４の窪み部４ａから加熱調理器Ｂの略中央部位に向けて臨むようにフード部１の前側に備えられた照明（ランプ）１６によって、調理者の手元は勿論、前側２ヶ所の熱口ｂにかけられている調理鍋Ｃの鍋底から加熱調理器Ｂ全体を万遍に、かつ、確実に照らすことができる。   Moreover, as shown by the dashed-dotted line in FIG. 1, an illumination (lamp) 16 provided on the front side of the hood portion 1 so as to face the substantially central portion of the heating cooker B from the recess 4 a of the rectifying plate 4. Thus, the entire cooking device B can be illuminated uniformly and reliably from the bottom of the cooking pan C applied to the two hot mouths b on the front side as well as the hand of the cook.

そして、使用頻繁が高い加熱調理器Ｂの前側２ヶ所の熱口ｂや調理鍋Ｃから舞いがってくる汚染空気Ｇは、略真上に位置している捕獲空間Ｍの両側の拡張空間Ｍ１において取り逃がすことなく、確実にキャッチして吸込み捕獲することができる。
つまり、両側の拡張空間Ｍ１は、前側２ヶ所の熱口ｂの略真上に位置し、しかも、吸気口１２からより多くの吸引力が伝播されて整流板４の延長縁部４ｂとの間に確保される吸込み隙間Ｓ１に勢い良く吸込み流速が作用するなどから、前側２ヶ所の熱口ｂや調理鍋Ｃから舞いがってくる汚染空気Ｇを取り逃がすことなく、両側の拡張空間Ｍ１にて確実にキャッチして吸込み捕獲し、屋外に排気することができる。 And the contaminated air G which flies from the hot mouth b of the front two places and the cooking pan C of the heating cooker B which is used frequently is expanded space M1 on both sides of the capture space M located almost directly above. It is possible to catch and suck in and capture without fail.
That is, the expansion spaces M1 on both sides are located substantially directly above the two heat ports b on the front side, and more suction force is propagated from the intake port 12 so that the space between the extended edge portion 4b of the rectifying plate 4 is increased. In the expansion space M1 on both sides, the suction flow velocity acts on the suction gap S1 that is secured at the front, so that the polluted air G flying from the two hot ports b and the cooking pan C is not released. It can be caught securely, sucked in, and exhausted outdoors.
