Description

本発明は、調理中に加熱調理器具や調理鍋などから舞い上がる湯煙や油煙などの汚染空気を吸い込み捕集するための深い捕獲空間を有するフード体の内部に送風機を正面向きの縦置きに設置している深型レンジフードに関する。 In the present invention, a blower is installed vertically in a hood body having a deep capture space for sucking and collecting contaminated air such as hot and cold smoke rising from cooking utensils and cooking pans during cooking. It relates to the deep type range hood.

レンジフードは、汚染空気を吸い込み捕集するための捕獲空間が浅いタイプの薄型レンジフードを除いて深型レンジフードと呼称されている。
この深型レンジフードは、高さ方向（キッチン天井方向）に深く形成されている捕獲空間を有するフード体の内部に、正面向きの縦置きに送風機を設置している。
そして、深型レンジフードは、フード体の前側（調理者側）を向いて開口されている送風機の吸引口の前方に、フード体の下向き開口部側に向けた斜め下向き姿勢で整流板を配置し、さらに、この整流板の下からフード体の背面板に向けて、フード体の下向き開口部側と送風機側とを仕切るための仕切り板を配置している（特許文献１および特許文献２などを参照）。
すなわち、従来の深型レンジフードでは、送風機のファンケーシングの高さに相当する縦幅で、フード体の両側面板間の横幅寸法よりもわずかに狭い横幅にて略横長矩形形状に形成されている整流板を、送風機の吸引口の前方に斜め下向き姿勢に配置している。
これにより、整流板の周囲各辺縁部と、仕切り板、そしてフード体の上面板および両側面板との間にそれぞれ形成される吸込み隙間により、汚染空気が勢い良く流速を速めて送風機が設置されている整流板の後方（裏側）に吸気されるようになっている。
特開２０００−７４４４１号公報（明細書中段落番号０００８、００１１、００２２および図４参照）特開２０００−７４４４２号公報（明細書中段落番号０００８、００１２および図１参照） The range hood is called a deep range hood except for a thin range hood with a shallow capture space for sucking and collecting contaminated air.
This deep type range hood has a blower installed vertically in a front direction inside a hood body having a capture space deeply formed in the height direction (kitchen ceiling direction).
The deep range hood has a rectifying plate placed in an obliquely downward posture toward the downward opening side of the hood body in front of the suction port of the blower that is open facing the front side (cooker side) of the hood body. Furthermore, a partition plate for partitioning the downward opening side of the hood body from the blower side is disposed from the bottom of the current plate toward the back plate of the hood body (Patent Document 1 and Patent Document 2, etc.) See).
That is, the conventional deep type range hood is formed in a substantially horizontally long rectangular shape with a width corresponding to the height of the fan casing of the blower and a width slightly smaller than the width between the side plates of the hood body. The rectifying plate is disposed in an obliquely downward posture in front of the suction port of the blower.
As a result, the air is vigorously increased by the suction gaps formed between the peripheral edges of the current plate, the partition plate, and the upper surface plate and both side surface plates of the hood body. The air is drawn into the back (back side) of the current plate.
JP 2000-74441 A (see paragraph numbers 0008, 0011, 0022 and FIG. 4 in the specification) Japanese Patent Laid-Open No. 2000-74442 (see paragraph numbers 0008 and 0012 and FIG. 1 in the specification)

ところで、従来の深型レンジフードでは、フード体の下向き開口部から捕獲空間に吸込み捕集された汚染空気を、斜め下向き姿勢の整流板に沿わせて周囲各辺縁部の吸込み隙間から送風機の吸引口の方向に向けて速やかに流入させて、該吸引口から排気ダクトを通して屋外に排気することができる。
しかしながら、加熱調理器や調理鍋などから舞い上がってくる汚染空気が、キッチン天井側などに拡散するなどのフード体の外側への漏洩を防ぐための吸引力（吸込み捕集力）をフード体の下向き開口部に有効に発生させることができない。すなわち、汚染空気を取り逃がさずに下向き開口部から捕獲空間に確実に引き寄せ捕集するといったレンジフードに求められる本来の捕獲性能が向上されていない課題が残されていた。 By the way, in the conventional deep type range hood, the polluted air sucked into the capture space from the downward opening of the hood body is collected along the rectifying plate in an obliquely downward posture from the suction gaps of the peripheral edges of the blower. It is possible to promptly flow in the direction of the suction port and to exhaust the air from the suction port through the exhaust duct.
However, the hood body has a suction force (suction collection force) that prevents the contaminated air that rises from the heating cooker or cooking pan from diffusing to the kitchen ceiling, etc. It cannot be generated effectively in the opening. That is, there remains a problem that the original capture performance required for the range hood is not improved such that the contaminated air is surely attracted and collected from the downward opening to the capture space without taking away the contaminated air.

なお、フード体の下向き開口部に強力な吸引力を発生させるための方策として、送風機のファンモータの出力を上げることが考えられるが、出力の大きいモータはコスト高であるばかりか、大型になる傾向にあるために、現状の送風機のファンケーシングに組み込むことが困難であり、実現性に乏しいものとなる。 As a measure for generating a strong suction force in the downward opening of the hood body, it is conceivable to increase the output of the fan motor of the blower. However, a motor with a large output is not only expensive but also large. Because of this tendency, it is difficult to incorporate it into the fan casing of the current blower, and the feasibility is poor.

そこで、本願発明者は、このような課題を解消するために、研究開発を重ねて本発明の創案に至ったものであり、送風機のファンモータの主力を上げずに、しかも、整流板自体に大きな改良などを加えることなく、送風機の吸引力をフード体の下向き開口部に有効に伝播させて、汚染空気を確実に捕獲し得るように改良された深型レンジフードを提供することにある。 Therefore, in order to solve such problems, the inventor of the present application has repeated research and development to arrive at the idea of the present invention, and without increasing the main force of the fan motor of the blower, and in addition to the current plate itself. An object of the present invention is to provide an improved deep range hood which can effectively capture the contaminated air by effectively propagating the suction force of the blower to the downward opening of the hood body without adding a great improvement.

前記課題を解決するために、本発明では、下向きに開口するフード体の捕獲空間の内部に、縦置きに送風機を設置し、この送風機の吸引口の前方に整流板を配置し、この整流板の周囲各辺縁部に沿って吸込み隙間を備えている深型レンジフードであって、
前記整流板と前記吸引口が開口されている前記送風機の開口壁面との間に気流抑止部材を備え、前記気流抑止部材は、前記フード体の下向き開口部側に位置する下側を除いて、前記開口壁面から前記整流板の方向に向けて立ち上げ形成される前記汚染空気の突き当たり部を備えていることを特徴とする。
ここで、前記整流板が、前記フード部の下向き開口部の方向に向けた斜め下向き姿勢に取り付けられている場合には、この斜め下向き姿勢の前記整流板に略沿う高さに合わせて前記突き当たり部が立ち上げ形成されていることが好適なものとなる。 In order to solve the above-described problem, in the present invention, a blower is installed vertically in a capture space of a hood body that opens downward, and a rectifying plate is disposed in front of the suction port of the blower. A deep range hood with suction gaps along each peripheral edge,
An airflow suppression member is provided between the current plate and the opening wall surface of the blower in which the suction port is opened, and the airflow suppression member is located on the downward opening side of the hood body, It has a contact portion of the contaminated air that is formed to rise from the opening wall surface toward the rectifying plate.
Here, when the rectifying plate is attached in an obliquely downward posture toward the downward opening of the hood portion, the abutment is made in accordance with a height substantially along the rectifying plate in the obliquely downward posture. It is preferable that the part is raised and formed.

また、前記整流板の上辺縁部とフード体の上面板との間に形成される吸込み隙間を狭くする垂下部材を、前記上面板に備えることが好適なものとなる。
さらに、前記整流板の下から前記フード体の背面板に向けて、前記フード体の下向き開口部側と前記送風機側とを仕切る仕切り板を配置していることが好適なものとなる。
また、前記整流板は、前記送風機のファンケーシングの高さに相当する縦幅で、前記フード体の両側面板間の横幅寸法よりもわずかに狭い横幅にて略横長矩形形状に形成されている。これにより、前記整流板の周囲各辺縁部と、前記仕切り板、そして前記フード体の上面板および両側面板との間に吸込み隙間が形成される。 In addition, it is preferable that the upper surface plate is provided with a hanging member that narrows a suction gap formed between the upper edge of the current plate and the upper surface plate of the hood body.
Furthermore, it is preferable that a partition plate for partitioning the downward opening side of the hood body and the blower side is disposed from the bottom of the rectifying plate toward the back plate of the hood body.
The straightening plate has a vertical width corresponding to the height of the fan casing of the blower, and is formed in a substantially horizontally long rectangular shape with a horizontal width slightly narrower than a horizontal width dimension between both side plates of the hood body. As a result, a suction gap is formed between each peripheral edge of the rectifying plate, the partition plate, and the top plate and both side plates of the hood body.

このような構成によれば、送風機の吸引力により、フード体の下向き開口部から捕獲空間に吸い込み捕集された湯煙や油煙などの汚染空気は、整流板に突き当たり、この整流板の周囲各辺縁部に沿って形成されている吸込み隙間から送風機が設置されている整流板の裏側に勢い良く流速を速めて吸い込まれていく。
すると、整流板の裏側に勢い良く吸い込まれてきた汚染空気のうち、整流板の裏側に配置されている気流抑止部材の突き当たり壁部が立ち上げ備えられていないフード体の下向き開口部側に位置する整流板の下側（気流抑止部材の下側）の吸込み隙間から吸い込まれる汚染空気は、気流抵抗（気流摩擦）を受けることなく、送風機の吸引口の方向に流れる。
その一方で、吸引口の手前において突き当たり壁部が立ち上げ備えられている整流板の下側を除く、整流板の周囲各辺縁部の吸込み口から吸い込まれる汚染空気は、突き当り壁部への突き当りによって吸込み流れが抑えられる気流の接触抵抗（摩擦）を受けて送風機の吸引口の方向に流れることとなる。
これにより、送風機の吸引力は、汚染空気の吸引口へ向けて流れが速やかに（スムーズに）行われる整流板の下側に形成されている吸込み隙間側に、より多く伝播されることになる。換言すれば、加熱調理器や調理鍋などから舞い上がってくる汚染空気をキッチン天井などの方向に取り逃がさずに引き寄せるための吸引力（吸込み捕集力）をフード体の下向き開口部に効率よく、集中的に伝播させることができる。 According to such a configuration, due to the suction force of the blower, polluted air such as fumes and oil smoke sucked into the capture space from the downward opening of the hood body hits the current plate, and each side around the current plate From the suction gap formed along the edge portion, the air is sucked at a rapid increase in the flow rate to the back side of the current plate where the blower is installed.
Then, out of the polluted air that has been sucked into the back side of the current plate, it is located on the downward opening side of the hood body where the abutting wall part of the airflow suppression member arranged on the back side of the current plate is not provided. The contaminated air sucked from the suction gap on the lower side of the rectifying plate (lower side of the airflow suppression member) flows in the direction of the suction port of the blower without receiving airflow resistance (airflow friction).
On the other hand, the contaminated air sucked in from the suction ports on the peripheral edges of the current plate, excluding the lower side of the current plate where the wall is raised in front of the suction port, flows into the wall. Upon receiving the contact resistance (friction) of the air flow that suppresses the suction flow by the bump, it flows in the direction of the suction port of the blower.
Thereby, the suction force of the blower is more propagated to the suction gap side formed on the lower side of the rectifying plate where the flow is performed quickly (smoothly) toward the suction port of the contaminated air. . In other words, the suction force (suction collection force) to draw the polluted air that soars from the heating cooker or cooking pan in the direction of the kitchen ceiling, etc. efficiently is applied to the downward opening of the hood body, It can be propagated intensively.

また、本発明では、前記気流抑止部材が、前記吸引口を形成するためのベルマウスを備えていることを特徴とする。 In the present invention, the airflow suppression member includes a bell mouth for forming the suction port.

このような構成によれば、付着した油（油脂分）などの汚れを拭き取るまたはシンクなどで丸洗いするときに、気流抑止部材をフード体内から取り外すことで、送風機の吸引口を内向きのラッパ形状に開口させるためのベルマウスをフード部の外に取り出して行うことができる。これにより、日常的なメンテナンス性の向上が図られる。 According to such a configuration, when wiping off dirt such as adhering oil (oil and fat) or washing it with a sink or the like, the airflow suppression member is removed from the hood body, so that the suction port of the blower has an inward trumpet shape. The bell mouth for opening to the outside can be taken out of the hood. As a result, daily maintenance can be improved.

本発明の深型レンジフードは、以上のように構成されていることで、送風機の吸引力を、フード体の下向き開口部に効率よく、集中的に伝播させて、加熱調理器や調理鍋などから舞い上がってくる汚染空気をキッチン天井などに取り逃がさずに引き寄せるための強力な吸引力（吸込み捕集力）を下向き開口部に発生させることができる。
これにより、整流板と吸引口が開口されている送風機の開口壁面との間に気流抑止部材を備えという簡単な構成で、汚染空気を逃がさずに確実に下向き開口部から捕獲空間に引き寄せ捕集するといったレンジフードに求められる本来の捕獲性能を格段に向上させることができる。
すなわち、送風機のファンモータの主力を上げることなく、しかも、整流板自体に大きな改良などを加えることなく、送風機の吸引力をフード体の下向き開口部に効率よく、且つ、集中的に伝播させて、キッチン天井などに汚染空気を取り逃がすことなく、下向き開口部に確実に引き寄せて捕集空間に吸込み捕獲することができる。 Since the deep range hood of the present invention is configured as described above, the suction force of the blower can be efficiently and intensively propagated to the downward opening of the hood body, such as a heating cooker or a cooking pan. It is possible to generate a strong suction force (suction trapping force) in the downward opening for drawing the polluted air soaring from the kitchen ceiling without escaping it.
As a result, the airflow suppression member is provided between the current plate and the opening wall surface of the blower in which the suction port is opened, and the contaminated air is reliably drawn from the downward opening to the capture space without being trapped. It is possible to significantly improve the original capture performance required for range hoods.
That is, without increasing the main power of the fan motor of the blower, and without greatly improving the rectifying plate itself, the suction force of the blower is efficiently and intensively propagated to the downward opening of the hood body. Without trapping contaminated air to the kitchen ceiling or the like, it can be reliably drawn into the downward opening and sucked into the collection space.

また、気流抑止部材をフード体から取り外すことで、送風機の吸引口を形成するためのベルマウスをフード体から取り外すことができる。
これにより、付着した油（油脂分）などの汚れを拭き取るまたはシンクなどで丸洗いするなどの日常的なメンテナンス性の向上を期待することができる。 Moreover, the bell mouth for forming the suction port of a fan can be removed from a hood body by removing an airflow suppression member from a hood body.
As a result, it is possible to expect improvement in daily maintenance such as wiping off dirt such as attached oil (oils and fats) or washing with a sink or the like.

この深型レンジフードＡは、図１に示すように、深型のフード体１内における背面板１−１側（キッチン壁Ｋ側）に位置させて送風機２を縦置きに設置している。これにより、送風機２の前方（前側）で高さ方向（キッチン天井の高さ方向）に深く、下向きに開口させた捕獲空間Ｍがフード体１内に形成されるようにしている。 ≪Configuration of range hood≫
Deep cooker hood A is installed almost directly above the heating cooker (not shown), and sucks and collects polluted air G, such as hot and cold smoke that rises from a cooking cooker such as a gas stove or cooking pan during cooking. The air is exhausted to the outside through the exhaust duct B.
As shown in FIG. 1, the deep range hood A is positioned on the back plate 1-1 side (kitchen wall K side) in the deep hood body 1 and the blower 2 is installed vertically. Thereby, the capture space M that is deep in the height direction (the height direction of the kitchen ceiling) in front (front side) of the blower 2 and opened downward is formed in the hood body 1.

さらに、レンジフードＡは、図１に示すように、整流板４の下方位置からフード体１の背面板１−１に向けたフード体１の前後方向において、該フード体１の下向き開口部６側と整流板４および送風機２側とを仕切るように仕切り板５を配置している。 In addition, as shown in FIG. 1, the rectifier 4 is arranged in the range hood A so as to conceal the blower 2 in front of the suction port 3 of the blower 2.
Accordingly, as shown in FIGS. 1, 2, and FIG. 3 to be described later, the peripheral edges 4-1 to 4-3 around the rectifying plate 4, the partition plate 5 to be described later, and the upper surface plate 1 of the hood body 1. -2 and both side plates 1-3, suction gaps S-1 to S-3 are respectively formed, and the contaminated air G vigorously increases the flow velocity from each of the suction gaps S-1 to S-3, thereby the current plate 4 is sucked into the back side (blower 2 side).
Further, as shown in FIG. 1, the range hood A includes a downward opening 6 of the hood body 1 in the front-rear direction of the hood body 1 from the lower position of the rectifying plate 4 toward the back plate 1-1 of the hood body 1. A partition plate 5 is arranged so as to partition the rectifying plate 4 and the blower 2 side.

≪フード体の構成≫
フード体１は、図１および図２に示すように、前面と下面とを開口させたフード部１ａと、このフード部１ａの前面開口部に取り外し自在に取り付けられる前面パネル１ｂとから下向きに大きく開口させた下向き開口部６を備え、高さ方向に深い捕獲空間Ｍを有する箱型に形成されている。 ≪Composition of food body≫
As shown in FIGS. 1 and 2, the hood body 1 is large downwardly from a hood portion 1a having a front surface and a lower surface opened and a front panel 1b removably attached to the front opening portion of the hood portion 1a. It has a downward opening 6 that is open and is formed in a box shape having a deep capture space M in the height direction.

As shown in FIGS. 1 and 2, the blower 2 has a fan motor 2b attached to a fan casing 2a attached to the upper surface plate 1-2 of the hood portion 1a in a substantially coaxial upright manner. An exhaust fan 2c is detachably attached to a motor shaft of a fan motor 2b that faces the motor casing 2a substantially coaxially with the motor body.
Incidentally, the exhaust fan 2c is a centrifugal fan (commonly referred to as a sirocco fan) having a high exhaust capability.

また、送風機２は、図１および図２に示すように、ボリュート形状に形成されているファンケーシング２ａの前面壁（開口壁面）１５に、後記する気流抑止部材１３に備えられるベルマウス７を内側に向けて装着されることによりラッパ口形状の吸引口３が形成されるようにしている。
さらに、送風機２は、ファンケーシング２ａの底部にオイル抜き孔８を備えている。これにより、ファンケーシング２ａの内側面や排気ファン２ｃの各羽根などへの汚染空気Ｇの接触によって汚染空気Ｇ中から分離捕獲される油脂分が、オイル抜き孔８から仕切り板５の上に滴下（流下）されて後記するオイル回収孔９よりオイルトレイ１０に回収されるようにしている。 Further, as shown in FIGS. 1 and 2, the blower 2 has a bell mouth 7 provided on an airflow suppression member 13 described later on a front wall (opening wall surface) 15 of a fan casing 2a formed in a volute shape. The suction port 3 having a trumpet shape is formed by being mounted toward the front.
Further, the blower 2 includes an oil drain hole 8 at the bottom of the fan casing 2a. As a result, the oil and fat components separated and captured from the contaminated air G due to the contact of the contaminated air G with the inner surface of the fan casing 2a and each blade of the exhaust fan 2c are dropped onto the partition plate 5 from the oil vent hole 8. (Flowing down) and then recovered to the oil tray 10 through an oil recovery hole 9 described later.

≪仕切り板の構成≫
仕切り板５は、前辺縁を除く残り三辺縁が、フード体１の背面板１−１、両側面板１−３にネジ止め、或いはスポット溶接やその他の固着手段によって固定される大きさを有する平面視で略矩形形状に形成されている。
そして、この仕切り板５は、図１および図２に示すように、周囲四辺縁から後辺縁（フード体１の背面板１−１）側における幅方向の中央部位に向かって漸次傾斜させたオイル回収勾配５ａを備え、このオイル油回収勾配５ａの合流下端部位にはオイル回収孔９を備えている。
また、仕切り板５は、前辺縁に前上がり傾斜状に折り曲げ立ち上げた立上り辺部５ｂを備え、残る後辺縁と両側辺縁にはフード体１の背面板１−１と両側面板１−３に固定される取付辺部５ｃを備えている。 ≪Partition plate configuration≫
The partition plate 5 has such a size that the remaining three edges excluding the front edge are fixed to the back plate 1-1 and both side plates 1-3 of the hood body 1 by screwing or spot welding or other fixing means. It has a substantially rectangular shape in plan view.
And this partition plate 5 was made to incline gradually toward the center part of the width direction in the rear edge (back plate 1-1 of the hood body 1) side from the surrounding four edges as shown in FIG.1 and FIG.2. An oil recovery gradient 5a is provided, and an oil recovery hole 9 is provided at the lower end portion of the merging oil oil recovery gradient 5a.

≪整流板の構成≫
図３は、整流板を裏側（送風機側）から見たときの斜視図である。ここでは、図１および図２を適宜参照しながら説明する。
整流板４は、送風機２のファンケーシング２ａの高さに相当する縦幅で、フード体１の両側面板１−３間の横幅寸法よりもわずかに狭い横幅にて正面視で略横長矩形形状に形成されている。
これにより、図１および図２に示すように、整流板４の周囲各辺縁部４−１〜４−３、つまり、図３に示すように、上辺縁部４−１、下辺縁部４−２、そして両側辺縁部４−３と、仕切り板５、そしてフード体１の上面板１−２および両側面板１−３との間に吸込み隙間Ｓ−１〜Ｓ−３がそれぞれ形成されるようにしている。
ここで、前記の横幅寸法よりもわずかに狭い横幅とは、図１および図２に示すように、整流板４の両側辺縁部４−３とフード体１の両側面板１−３との間にそれぞれ形成される両側の吸込み隙間Ｓ−３が、特に、整流板４の下辺縁部４−２と仕切り板５との間に形成される吸込み隙間Ｓ−２よりも狭くなるように、整流板４の横幅寸法を設定することを意味するものである。 <Composition of current plate>
FIG. 3 is a perspective view when the current plate is viewed from the back side (blower side). Here, description will be made with reference to FIGS. 1 and 2 as appropriate.
The rectifying plate 4 has a vertical width corresponding to the height of the fan casing 2 a of the blower 2, and has a lateral width slightly narrower than the horizontal width between both side plates 1-3 of the hood body 1, and has a substantially horizontally long rectangular shape in front view. Is formed.
Accordingly, as shown in FIGS. 1 and 2, each of the peripheral edges 4-1 to 4-3 around the current plate 4, that is, as shown in FIG. 3, the upper edge 4-1 and the lower edge 4 -2 and suction gaps S-1 to S-3 are respectively formed between the side edge portions 4-3, the partition plate 5, and the upper surface plate 1-2 and both side surface plates 1-3 of the hood body 1. I try to do it.
Here, as shown in FIGS. 1 and 2, the width slightly narrower than the width dimension described above is defined between the side edges 4-3 of the rectifying plate 4 and the side plates 1-3 of the hood body 1. The suction gaps S-3 on both sides formed respectively on the rectifying plate 4 are narrower than the suction gap S-2 formed between the lower edge 4-2 of the rectifying plate 4 and the partition plate 5, in particular. This means that the width of the plate 4 is set.

また、整流板４は、図１および図３に示すように、フード体１の前面パネル１ｂ側に向けて緩やかに湾曲させた側面視で略弓なり形状に形成されている。
これにより、下向き開口部６から捕獲空間Ｍに吸込み捕集される汚染空気Ｇが整流板４に突き当たり、整流板４の表面に沿って上下両側の周囲各辺縁部４−１〜４−３の方向（吸込み隙間Ｓ−１〜Ｓ−３の方向）に整流されるようにしている。すなわち、フード部１の下向き開口部６に向けて加熱調理器から略垂直に舞い上がってくる汚染空気Ｇを整流板４の表面全体に万遍に突き当て整流板４の整流機能が発揮されるようにしている。 Further, as shown in FIGS. 1 and 3, the current plate 4 is formed in a substantially bow shape in a side view that is gently curved toward the front panel 1 b side of the hood body 1.
As a result, the contaminated air G sucked and collected from the downward opening 6 into the capture space M hits the rectifying plate 4, and the peripheral edges 4-1 to 4-3 on both the upper and lower sides along the surface of the rectifying plate 4. Rectified in the direction (the suction gaps S-1 to S-3). That is, the rectifying function of the rectifying plate 4 is exerted so that the contaminated air G that rises substantially vertically from the heating cooker toward the downward opening 6 of the hood portion 1 is universally abutted against the entire surface of the rectifying plate 4. I have to.

そして、このように形成されている整流板４は、図１に示すように、フード体１の上面板１−２に備えられている垂下部材１１に支持部材１２を介して、上辺縁部４−１側が回動可能で適宜係脱自在に支持され、送風機２の前面または気流抑止部材１３或いは後記する隠蔽パネル２４の下側に備えられている係脱部材１４によって、下辺縁部４−２側が係脱自在に支持されている。
これにより、気流抑止部材１３を送風機２の前面から取り外してシンクなどで洗浄するときや、整流板４自体を洗浄するときなどにおいて整流板４をフード体１から簡単に取り外すことができるようにしている。 As shown in FIG. 1, the rectifying plate 4 formed in this way is connected to the hanging member 11 provided on the upper surface plate 1-2 of the hood body 1 via the support member 12 and the upper edge portion 4. The lower edge portion 4-2 is supported by the engagement / disengagement member 14 provided on the front side of the blower 2 or the airflow suppression member 13 or the concealment panel 24 described later. The side is supported detachably.
Thus, the rectifying plate 4 can be easily removed from the hood body 1 when the airflow suppressing member 13 is removed from the front surface of the blower 2 and cleaned with a sink or when the rectifying plate 4 itself is cleaned. Yes.

≪垂下部材の構成≫

［作用説明］
次に、このように形成されている気流抑止部材１３を、整流板４と送付機２との間で、ファンケーシング２ａの前面壁１５に取り付けて備えた本実施形態に係るレンジフード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。
送風機２の吸引力によりフード体１の下向き開口部６から捕獲空間Ｍに吸い込み捕集された湯煙や油煙などの汚染空気Ｇが、整流板４に突き当たり、整流板４の周囲各辺縁部４−１〜４−３に沿って形成されている吸込み隙間Ｓ−１〜Ｓ−３から整流板４の裏側に勢い良く流速を速めて吸い込まれて吸引口３の方向に流れるときに、図１に示すように、気流抑止部材１３の突き当たり壁部１３ｂ，１３ｃが立ち上げ備えられていない整流板４の下辺縁部４−２側（吸込み隙間Ｓ−２側）から吸い込まれた汚染空気Ｇ−１は、障害物に突き当たるなどの接触抵抗（摩擦）を受けることなく、吸引口３の方向に流れ、該吸引口３からファンケーシング２ａ内に吸気され、排気ダクトＢを通って屋外に排気される。
その一方で、吸引口３の手前に突き当たり壁部１３ｂ，１３ｃが立ち上げ備えられている整流板４の上辺縁部４−１および両側辺縁部４−３側（吸込み隙間Ｓ−１，Ｓ−３側）からそれぞれ吸い込まれた汚染空気Ｇ−２は、突き当たり部１３ｂ，１３ｃへの突き当たるように接触によって吸引口３の方向への吸込み流れが抑えられる。つまり、流れの障害物となる突き当たり部１３ｂ，１３ｃへの突き当たり接触によって吸込み流速が減速される接触抵抗を受けながら吸引口３の方向に流れることとなる。
これにより、吸引口３からの吸引力は、吸込み隙間Ｓ−２から吸引口３へ向けて汚染空気Ｇ−１の流れが速やかに（スムーズに）行われる整流板４の下端縁部４−２に沿って形成されている吸込み隙間Ｓ−２側に、より多く伝播されることになる。換言すれば、加熱調理器や調理鍋などから舞い上がってくる汚染空気Ｇをキッチン天井側などに取り逃がさずに引き寄せるための吸引力（吸込み捕集力）を、フード体１の下向き開口部６に効率よく、集中的に伝播させることができる。 [Description of operation]
Next, the action of the range hood A according to the present embodiment in which the airflow suppression member 13 formed in this way is attached to the front wall 15 of the fan casing 2a between the rectifying plate 4 and the transmitter 2 is provided. A brief explanation will be given. Here, description will be made with reference to FIGS. 1 and 2 as appropriate.
Contaminated air G such as hot and cold smoke or oil smoke sucked and collected from the downward opening 6 of the hood body 1 by the suction force of the blower 2 strikes the rectifying plate 4, and each peripheral edge 4 around the rectifying plate 4. When the suction gaps S-1 to S-3 formed along the lines -1 to 4-3 are sucked into the back side of the rectifying plate 4 with a rapid increase in the flow velocity and flow toward the suction port 3, FIG. As shown in FIG. 4, the contaminated air G− sucked in from the lower edge portion 4-2 side (suction gap S-2 side) of the rectifying plate 4 where the abutting walls 13b and 13c of the airflow suppression member 13 are not raised and provided. 1 flows in the direction of the suction port 3 without receiving contact resistance (friction) such as hitting an obstacle, and is sucked into the fan casing 2a from the suction port 3 and exhausted to the outside through the exhaust duct B. The
On the other hand, the upper edge part 4-1 and both side edge parts 4-3 side (suction gaps S-1, S) of the rectifying plate 4 provided with the abutting wall parts 13b, 13c rising up before the suction port 3 are provided. The contaminated air G-2 sucked from the (-3 side) is restrained from being sucked in the direction of the suction port 3 by contact so as to abut against the abutting portions 13b and 13c. That is, it flows in the direction of the suction port 3 while receiving contact resistance that reduces the suction flow velocity due to the contact with the contact portions 13b and 13c that become obstacles to the flow.
As a result, the suction force from the suction port 3 is such that the flow of the contaminated air G-1 from the suction gap S-2 toward the suction port 3 is performed quickly (smoothly). Will be propagated more toward the suction gap S-2 formed along the line. In other words, a suction force (suction collecting force) for attracting the contaminated air G soaring from the heating cooker, cooking pan, etc. without taking it to the kitchen ceiling or the like is applied to the downward opening 6 of the hood body 1. It can be efficiently and intensively propagated.

図７は、本実施形態に係る気流抑止部材を備えた深型レンジフードの他の実施形態を示す縦断側面図である。
斯かる実施形態に係る深型レンジフードＡ−１は、図７に示すように、整流板４０の縦断面形状を変えた以外の構成要素においては前記した実施形態の深型レンジフードＡと基本的に同じであることから、同じ構成要素に同じ符合を付することにより重複説明は省略する。
すなわち、整流板４０の側面視形状は、図７に示すように、周知のように平らな面状に形成されている。そして、前記した支持部材１２と係脱部材１４とによって斜め下向き姿勢にて送風機２の前方に配置される整流板４に沿わせて気流抑止部材１３の左右両側の突き当たり部１３ｃを漸次傾斜させている。 FIG. 7 is a longitudinal side view showing another embodiment of the deep range hood provided with the airflow suppressing member according to the present embodiment.
As shown in FIG. 7, the deep range hood A-1 according to such an embodiment is basically the same as the deep range hood A of the above-described embodiment except for the configuration in which the longitudinal sectional shape of the rectifying plate 40 is changed. Therefore, the same components are denoted by the same reference numerals, and redundant description is omitted.
That is, the side view shape of the current plate 40 is formed as a flat surface as is well known, as shown in FIG. Then, the abutting portions 13c on both the left and right sides of the airflow suppressing member 13 are gradually inclined along the rectifying plate 4 disposed in front of the blower 2 in an obliquely downward posture by the support member 12 and the engagement / disengagement member 14 described above. Yes.

なお、図示を省略しているが、捕獲空間Ｍに吸い込み捕獲される全ての汚染空気Ｇを、整流板４の下辺縁部４−２の吸込み隙間Ｓ−２からファンケーシング２ａの吸引口３の方向に流れるように、吸込み隙間Ｓ−２を除く、整流板４の上辺縁部４−１と両側辺縁部４−３との三辺縁の吸込み隙間Ｓ−１，Ｓ−３を塞いだ構成とすることで、吸込み隙間Ｓ−２を介してフード体１の下向き開口部６に伝播される汚染空気Ｇをキッチン天井などの方向に取り逃がさずに引き寄せるための吸引力（吸込み捕集力）を、フード体１の下向き開口部６により一層効果的に伝播させることができる。
すなわち、気流抑止部材１３に変えて、整流板４の下辺縁部４−２側を除く、上辺縁部４−１と両側辺縁部４−３との三辺縁の吸込み隙間Ｓ−１，Ｓ−３を塞ぐ隙間閉鎖部材を、整流板４と送風機２の前面との間に備える構成とすることも考えられる。しかし、加熱調理器から舞い上がってくる汚染空気Ｇは、図１および図７に示すように、フード体１のフード部１ａの下側のみならず、前面パネル１ｂの下側から捕獲空間Ｍに吸い込み捕集されて、前面パネル１ｂの内側面に沿って捕獲空間Ｍの上部側、両側の方向へ流れがあるために、上辺縁部４−１と両側辺縁部４−３との三辺縁の吸込み隙間Ｓ−１，Ｓ−３を塞ぐことなく、整流板４の裏側への汚染空気Ｇ−２の吸い込みを必要とするものである。 Although illustration is omitted, all the contaminated air G sucked and captured in the capture space M is drawn from the suction gap S-2 of the lower edge 4-2 of the rectifying plate 4 to the suction port 3 of the fan casing 2a. The suction gaps S-1 and S-3 on the three sides of the upper edge portion 4-1 and both side edge portions 4-3 of the current plate 4 except for the suction gap S-2 are closed so as to flow in the direction. By adopting the configuration, the suction force (suction collection force) for drawing the contaminated air G propagated to the downward opening 6 of the hood body 1 through the suction gap S-2 without escaping in the direction of the kitchen ceiling or the like. ) Can be more effectively propagated through the downward opening 6 of the hood body 1.
That is, instead of the airflow suppression member 13, the suction gaps S-1 at the three sides of the upper side edge part 4-1 and the side edge parts 4-3 excluding the lower side edge part 4-2 side of the rectifying plate 4 are provided. It is also conceivable to provide a gap closing member that closes S-3 between the current plate 4 and the front surface of the blower 2. However, as shown in FIGS. 1 and 7, the contaminated air G that rises from the heating cooker is sucked into the capture space M not only from the lower side of the hood portion 1a of the hood body 1 but also from the lower side of the front panel 1b. Since it is collected and flows in the direction of the upper side and both sides of the capture space M along the inner surface of the front panel 1b, the three edges of the upper edge part 4-1 and both edge parts 4-3 Therefore, the contaminated air G-2 needs to be sucked into the back side of the rectifying plate 4 without closing the suction gaps S-1 and S-3.
