Description

【０００１】
【発明の属する技術分野】
本発明は、空気調和の対象となる空間に面して配置され、この空間内の雰囲気に対して空気調和用の気体の拡散・混合が効率的に行える吹出口装置に関する。
【０００２】
【従来の技術】
近年、低温冷風（１０℃前後に冷した空気）を利用した空気調和システムが利用されるようになってきており、搬送される調和空気と室内空気との大温度差化に伴って送風量の低減が図れ、これによって空気調和設備にとどまらず建物に至るまで諸コストの低減が可能となっている。このような空気調和システムにおける吹出口装置の一例として、従来、図８に示すものがあった。この図８は従来の吹出口装置の概略構成断面図である。
【０００３】
前記図８において従来の吹出口装置１００は、天井５０内に配設され、ダクト５１と接続されて調和空気を供給される円筒形のネック部１０１と、室内空間側に矩形拡開状に形成されてなる開口枠体１０２と、前記ネック部１０１ａ内部に配設され、傾斜羽根１０３ａを複数枚放射状に配置して一体に形成され、気流に旋回を与える旋回羽根体１０３と、この旋回羽根体１０３の下流側の開口領域内所定位置に配設される角錐状の吹出コーン１０４と、中央に矩形の開口孔１０５ａを有する板状体で形成され、吹出コーン１０４の下方に所定間隔離して配設される誘引フェース１０５とを備える構成である。
【０００４】
上記した従来の吹出口装置１００では、ダクト５１から送られた調和空気がネック部１０１内の旋回羽根体１０３による案内で旋回流となった後、吹出コーン１０４により開口領域の外周側に導かれ、略水平に室内に吹出す。また、吹出口周囲の室内空気が調和空気の室内へ吹出す気流に誘引されて、中央の開口孔１０５ａから誘引フェース１０５と吹出コーン１０４の間に導かれ、さらに横向きに吹出す調和空気と混合して室内空間に拡散する。
【０００５】
一般に、低温冷風吹出の場合、風量が絞られて風速が低下すると、著しい拡散性能の低下をきたし、吹出口直下においてドラフトが発生する可能性がある。この吹出口装置１００では、低温冷風の小風量吹出時にも拡散性能を保持するよう、ネック部１０１に旋回羽根体１０３を配設することで気流に旋回を与え、ネック部１０１での風速の低下を抑えている。また、高い誘引性能を持たせるために、吹出コーン１０４下部に誘引フェース１０５を配設し、吹出コーン１０４との間のスリットから吹出口近傍の室内空気を誘引させる形状としている。このように、従来の吹出口装置１００は、室内空気との混合、拡散を短時間で強力に行え、ドラフトの発生も抑えられるといった特長を有している。
【０００６】
【発明が解決しようとする課題】
従来の吹出口装置は以上のように構成されていたことから、常に吹出角度が横向きに固定されて水平気流となり、冷房に関しては、室内空気に冷気を急速に混合・拡散させて短時間に効率よく空気調和が行え、また、ドラフトを感じさせない等の特長を有していた。しかし、他の吹出パターンへ変更ができず、特に暖房の場合には室内下方の居住域まで暖気を到達させるのが困難になり、空気調和に時間がかかるという課題を有した。また、上記以外に、中コーンや中パンの上下位置を変えて吹出しの向きを切替えるタイプの吹出口装置も従来からあったが、低温冷風吹出に対しては拡散性能が十分でなく、場合によってはドラフトが生じてしまうという課題を有していた。
【０００７】
本発明は前記課題を解消するためになされたもので、低温冷風吹出に対する高拡散性能を保ったまま吹出パターンを変化させられ、様々な空気調和状況に柔軟に対応できる吹出口装置を提供することを目的とする。
【０００８】
【課題を解決するための手段】
本発明に係る吹出口装置は、天井内に配設され、一端側開口に空気調和用の気体が供給される略筒状体で形成されるネック部と、当該ネック部の他端側開口に連設され、ネック部に連通し且つネック部の他端側開口から拡大する開口領域を有し、空気調和対象空間側端部から前記ネック部との連設部分まで所定の奥行寸法とされて前記気体を空気調和対象空間へ吹出す開口枠体と、前記ネック部内横断面形状と略同形状の略板状体で形成され、通風孔を放射状配置で所定角度ピッチに複数形成され、中心部に所定の大きさの中央開口部が穿設され、前記ネック部内側所定位置に配設される案内板と、所定形状の板状体で形成され、前記各通風孔における案内板の放射方向に略一致する縁に前記板状体の所定の縁部を一体に連設されて所定角度に傾斜した状態で配設される複数の傾斜羽根と、前記案内板の中央開口部を開閉自在に配設される閉塞蓋と、当該閉塞蓋の開閉を行う開閉手段とを備え、前記開閉手段による中央開口部の開閉で開口枠体から吹出す気流の吹出パターンを変化させるものである。このように本発明によれば、ネック部内側の案内板に傾斜羽根が放射状に複数配置され、各通風孔を通過する気流が傾斜羽根の所定の傾斜角度に沿って旋回流になると共に、案内板の中央開口部を開閉する閉塞蓋及び開閉手段が配設され、中央開口部に気流を通すか通さないかを切替えて開口枠体内での旋回流の挙動を変化させることにより、吹出す気流に偏流を生じさせずに各方向へ均等に吹出せ、且つ風量に関わりなく空気調和対象空間内空気への気流の混合・拡散が速くドラフトが生じにくいといった旋回流の性質を保持しつつ、開口枠体から吹出す気流の吹出パターンを例えば水平から垂直へと大きく変化させられることとなり、設置箇所や空気調和対象空間の状況に応じた空気調和が行え、空気調和能力が大幅に向上する。
【０００９】
また、本発明に係る吹出口装置は、天井内に配設され、一端側開口に空気調和用の気体が供給される略筒状体で形成されるネック部と、当該ネック部の他端側開口に連設され、ネック部に連通し且つネック部の他端側開口から拡大する開口領域を有し、空気調和対象空間側端部から前記ネック部との連設部分まで所定の奥行寸法とされて前記気体を空気調和対象空間へ吹出す開口枠体と、前記ネック部内横断面形状と略同形状の略板状体で形成され、通風孔を放射状配置で所定角度ピッチに複数形成され、前記ネック部内側にネック部軸方向へ移動自在に配設される案内板と、所定形状の板状体で形成され、前記各通風孔における案内板の半径方向に略一致する縁に前記板状体の所定の縁部を一体に連設されて所定角度に傾斜した状態で配設される複数の傾斜羽根と、前記案内板のネック部軸方向位置を調整する位置調整手段とを備え、前記位置調整手段による案内板の位置調節で開口枠体から吹出す気流の吹出パターンを変化させるものである。このように本発明によれば、ネック部内側の案内板に傾斜羽根が放射状に複数配置され、各通風孔を通過する気流が傾斜羽根の所定の傾斜角度に沿って旋回流になると共に、案内板がネック部内で軸方向移動自在に配設され、ネック部内での案内板位置すなわち傾斜羽根位置を調整して開口枠体内での旋回流の挙動を変化させることにより、吹出す気流に偏流を生じさせずに各方向へ均等に吹出せ、且つ風量に関わりなく空気調和対象空間内空気への気流の混合・拡散が速くドラフトが生じにくいといった旋回流の性質を保持しつつ、開口枠体から吹出す気流の吹出パターンを例えば水平から垂直へと大きく変化させられることとなり、設置箇所や空気調和対象空間の状況に応じた空気調和が行え、空気調和能力が大幅に向上する。
【００１０】
また、本発明に係る吹出口装置は必要に応じて、前記案内板が、中心部に所定の大きさの中央開口部を穿設されると共に、前記案内板の中央開口部を開閉自在に配設される閉塞蓋と、当該閉塞蓋の開閉を行う開閉手段とを備えるものである。このように本発明によれば、案内板中心に中央開口部を形成すると共に閉塞蓋を開閉自在に配設し、案内板位置の調整に加えて中央開口部への気流の流通を切替可能として開口枠体内での旋回流の挙動を大幅に変化させられることにより、より多様な吹出パターンの変化を得られることとなり、状況に応じて最も効率的な吹出パターンを適宜選択することができ、空気調和能力をさらに向上させられる。
【００１１】
また、本発明に係る吹出口装置は必要に応じて、前記開口枠体が、前記ネック部の他端側開口から急激に拡大する前記他端側開口より大きな開口領域を有してなるものである。このように本発明によれば、開口枠体がネック部の他端側開口との連設部分から急激に拡大し、且つ空気調和対象空間側端部まで所定寸法を確保した開口領域を有するように形成され、ネック部から出た旋回流が急拡大した開口枠体の内側隅部分に適度に生じる剥離域（負圧域）によって外周方向に導かれ、気流の向きを横向きに大きく湾曲させることにより、空気調和対象空間側開口から横向きに周囲各方向へ吹出せることとなり、他にコーン、遮閉板等の気流案内手段を用いずに気流の導入方向に対して略垂直な横向きの吹出を行うことができ、簡略化した構造として大幅なコストダウンが図れる。
【００１２】
また、本発明に係る吹出口装置は必要に応じて、前記案内板が、放射状配置で複数の所定形の切込みを形成される略板状体からなり、前記切込みに基づいて前記略板状体の複数の所定部分を所定角度に折曲して傾斜させ、複数の一体化した前記傾斜羽根とすると共に、当該傾斜羽根を折曲させて得られた開口部分を前記通風孔となすものである。このように本発明によれば、傾斜羽根を略板状体である案内板の折曲げで一体に形成していることにより、取扱性に優れ、製造が容易でコストダウンを図れると共に、傾斜羽根の折曲の具合をそれぞれ調整することで通風孔を通過する気流の吹出角度の調整も容易に行え、傾斜羽根の角度変化で旋回流の状態を様々に得られ、空気調和対象空間側の環境条件に適切に対応でき、空気調和能力を高められる。
【００１３】
また、本発明に係る吹出口装置は必要に応じて、前記傾斜羽根及び案内板が、各縁部分の表面に植毛を施されるものである。このように本発明によれば、傾斜羽根及び案内羽根の縁部分に植毛を施すことにより、風切り音の発生を防ぐと共に、上流から伝播する音を吸収でき、空気調和対象空間側開口から漏れる騒音を減少させられる。
【００１４】
【発明の実施の形態】
（本発明の第１の実施の形態）
以下、本発明の第１の実施の形態に係る吹出口装置を図１〜図３に基づいて説明する。この図１は本実施の形態に係る吹出口装置の概略構成縦断面図、図２は本実施の形態に係る吹出口装置の底面図、図３は本実施の形態に係る吹出口装置による吹出状態説明図を示す。
【００１５】
前記各図に示すように、本実施の形態に係る吹出口装置は、天井５０内に配設され、一端側開口でダクト５１と接続されて調和空気を供給される略円筒形状のネック部１１と、このネック部１１の他端側開口に連設され、ネック部１１に連通する開口領域を有して調和空気を室内空間へ吹出す開口枠体１２と、前記ネック部１１内径と略同径の略円板体で形成され、中心部に所定の大きさの中央開口部１３ａが穿設され、その外周側に複数の所定形の切込みを放射状配置で周方向所定ピッチに複数形成され、この切込みに基づいて略円板体の複数の所定部分を所定角度に折曲して傾斜させ、複数の傾斜羽根１４とすると共に、この傾斜羽根１４を折曲させて得られた開口部分を通風孔１３ｂとして、ネック部１１内側の他端側開口近傍位置に配設される案内板１３と、前記案内板１３の中央開口部１３ａを開閉自在に配設される閉塞蓋１５と、一端部を前記ネック部１１に固定され、他端部を前記閉塞蓋１５に固定されて配設され、調和空気の温度に応じて伸縮し、案内板１３に対し閉塞蓋１５を上下動させて中央開口部１３ａを開閉する開閉手段としての温度センサ１６とを備える構成である。
【００１６】
前記開口枠体１２は、前記ネック部１１の他端側開口への連設部分の矩形開口領域が室内空間側へ向うに従って拡大する矩形拡開状に形成される構成であり、室内空間側端部からネック部１１との連設部分まで所定の奥行寸法を有してなる構成である。
【００１７】
前記傾斜羽根１４は、案内板１３に対して折曲部分が半径方向をなすよう配置され、気流が案内板１３の接線方向にそれぞれ吹出すように形成される構成である（図２参照）。
【００１８】
次に、前記構成に基づく吹出口装置における吹出動作について説明する。ダクト５１から送られた調和空気は、ネック部１１内を下方に進み、放射状に配置された各傾斜羽根１４の傾斜に沿ってそれぞれ案内板１３の接線方向斜め下向きに案内されながら、通風孔１３ｂを通過することから、案内板１３下流側で各気流が合成されてネック部１１内壁に沿った旋回速度成分を有する旋回流となる。
【００１９】
ここで、暖房の場合は、暖気によって案内板１３上流側の温度センサ１６が伸び、閉塞蓋１５を案内板１３に向けて下降させるように作用し、案内板１３の中央開口部１３ａが閉塞される。これにより、暖気は通風孔１３ｂのみを通過することとなる。
【００２０】
暖気は、旋回を保ちながら開口枠体１２を下方に進み、下向きに室内空間に吹出す。軽い暖気を旋回流として天井５０から下向きに吹出すことで、旋回流による室内空気の誘引、混合の促進が図れ、短時間に居住域まで確実に暖房効果を得られる。
【００２１】
一方、冷房の場合は、冷気によって温度センサが縮み、閉塞蓋１５を案内板１３に対し上昇させ、案内板１３の中央開口部１３ａが開放される。これにより、冷気が通風孔１３ｂだけでなくこの中央開口部１３ａからも下方に達する。
【００２２】
通常、旋回流の中心は、気流が滞ってほぼ停止し、圧力も低くなった状態となっており、旋回流はこの滞った中心部分を取巻いてその周りを回転する。中央開口部１３ａを開放して上流側から気流が通ってくるようにすると、この旋回流の中心部分に下向きの気流が生じると共に圧力も高まるため、旋回流の内外のバランスが保てなくなり、旋回流が遠心方向に広がり、開口枠体１２の内面に沿って横向きに吹出すこととなる。横向きの気流となっても、旋回成分によって各方向に偏りなく吹出せる。
【００２３】
こうして、冷気は開口枠体１２から室内空間に略水平に吹出される。室内の空気より重い冷気を開口枠体１２から水平各方向に吹出すと共に、室内空気を強力に誘引して混合できることから、風量に関わりなく拡散性能を十分に発揮でき、冷却効果を著しく高めて短時間に室内を冷すことができると共に、ドラフトを起さない。また、冷気を開口枠体１２から各方向に吹出せることから、従来の矩形の吹出口の場合に冷気の吹出しにくかったコーナ部分で生じていた結露も確実に抑えられる。
【００２４】
このように、本実施の形態に係る吹出口装置では、ネック部１１断面を略円形状とし、案内板１３に傾斜羽根１４を放射状に配置し、各傾斜羽根１４の傾斜に沿わせて旋回流を生じさせると共に、案内板１３中心の中央開口部１３ａの開閉を切替え、水平吹出と垂直吹出を切替えることから、旋回流の誘引・拡散効果を生かしながらより調和空気温度に応じた吹出パターンが選択でき、空気調和能力が大幅に向上することとなる。
【００２５】
（本発明の第２の実施の形態）
本発明の第２の実施の形態に係る吹出口装置を図４〜図６に基づいて説明する。この図４は本実施の形態に係る吹出口装置の概略構成縦断面図、図５は本実施の形態に係る吹出口装置の底面図、図６は本実施の形態に係る吹出口装置による吹出状態説明図を示す。
【００２６】
前記各図に示すように、本実施の形態に係る吹出口装置は、前記第１の実施の形態と同様、ネック部２１と、開口枠体２２と、案内板２３と、傾斜羽根２４とを備える一方、異なる構成として、開口枠体２２の形状をネック部２１との連設位置から急激に拡大させた矩形箱状とし、また、案内板２３から中央開口部を省き、位置調整手段としての温度センサ２５で直接案内板２３を上下動させる構成を有するものである。
【００２７】
前記案内板２３は、温度センサ２５を介してネック部２１の他端側開口近傍に所定範囲上下動可能に配設され、温度センサ２５の温度による伸縮に伴ってネック部２１に対し上下動する仕組みとなっている。
【００２８】
次に、前記構成に基づく吹出口装置における吹出動作について説明する。前記第１の実施形態と同様、ダクト５１から送られた調和空気は、ネック部２１内を下方に進み、放射状に配置された各傾斜羽根２４の傾斜に沿ってそれぞれ案内板２３の接線方向斜め下向きに案内されながら、通風孔２３ａを通過することから、案内板２３下流側で各気流が合成されてネック部２１内壁に沿った旋回速度成分を有する旋回流となる。
【００２９】
ここで、暖房の場合は、暖気によって案内板２３上流側の温度センサ２５が伸び、案内板２３を上昇させるように作用し、案内板２３がネック部２１の他端側開口から離れた状態となる。暖気は、上昇した案内板２３の通風孔２３ａを通過し、ネック部２１内壁に沿って旋回を保ちながら開口枠体２２に達し、この開口枠体２２から下向きに室内空間に吹出す。前記第１の実施形態と同様、軽い暖気を旋回流として天井５０から下向きに吹出すことで、旋回流による室内空気の誘引、混合の促進が図れ、短時間に居住域まで確実に暖房効果を得られる。
【００３０】
一方、冷房の場合は、冷気によって温度センサが縮み、案内板２３を下降させてネック部２１の他端側開口直近に位置させる。
【００３１】
傾斜羽根２４に沿って通風孔２３ａを通過した各気流が、ネック部２１内壁に沿って合成されることで旋回速度成分を有する旋回流となるが、案内板２３を下降させた場合、通風孔２３ａ通過後に沿うネック部２１長さが十分でないことから、流れが旋回流として十分発達できず、開口枠体２２内へ傾斜羽根２４に沿った方向にそのまま流れていこうとする速度成分が残る。
【００３２】
ネック部２１から開口枠体２２への流れは、連設部分が急拡大しているために、流れに剥離が生じ、開口枠体２２の内側隅部に剥離域が生じる。暖房の場合、案内板２３を上方位置においたことで旋回流が十分発達し、剥離した流れが開口枠体２２の内側壁に再付着せず、旋回流がそのまま下方へ吹出すが、冷房の場合、旋回流が未発達のために旋回流が遠心方向に広がり、流れ自体が剥離域に沿って大きく横向きに湾曲して、剥離した流れが開口枠体２２の内側壁に再付着する。これにより、気流はそのまま開口枠体２２から横向きに吹出すこととなる。横向きの気流となっても、流れの旋回成分によって各方向に偏りなく吹出せる。
【００３３】
こうして、冷気は開口枠体２２から室内空間に略水平に吹出される。室内の空気より重い冷気を開口枠体２２から水平各方向に吹出すと共に、室内空気を強力に誘引して混合できることから、風量に関わりなく拡散性能を十分に発揮でき、冷却効果を著しく高めて短時間に室内を冷すことができると共に、ドラフトを起さない。また、前記第１の実施形態と同様、冷気を開口枠体２２から各方向に吹出せることから、従来の矩形の吹出口の場合に冷気の吹出しにくかったコーナ部分で生じていた結露も確実に抑えられる。
【００３４】
このように、本実施の形態に係る吹出口装置では、ネック部２１断面を略円形状とし、案内板２３に傾斜羽根２４を放射状に配置し、各傾斜羽根２４の傾斜に沿わせて旋回流を生じさせると共に、案内板２３のネック部２１内位置を切替え、水平吹出と垂直吹出を切替えることから、旋回流の誘引・拡散効果を生かしながらより調和空気温度に適した吹出パターンが選択でき、空気調和能力が大幅に向上することとなる。
【００３５】
なお、前記実施の形態に係る吹出口装置において、案内板２３の中心は閉じられた構成としているが、この他、前記第１の実施の形態と同様に、案内板２３の中心に所定の大きさの中央開口部を穿設すると共に、この中央開口部を開閉自在に配設される閉塞蓋、並びに案内板２３に対し閉塞蓋を上下動させて中央開口部を開閉する温度センサを備える構成とすることもでき、案内板２３位置調節と共に中央開口部の開閉により吹出パターンを複雑に変化させられる。例えば、案内板２３が下方位置の場合に中央開口部を開放すると、閉塞の場合と同様水平吹出となるが、案内板２３が上方位置の場合、中央開口部を開放すると、垂直に吹出すものの、旋回流がより遠心方向に広がって幅のある旋回流となり、室内空気の誘引、混合が促進されて空気調和効果がより短時間に得られることとなる。
【００３６】
また、前記第１及び第２の各実施の形態に係る吹出口装置において、案内板上の傾斜羽根は前記各図中に示す枚数に限らず、周方向に等ピッチで配設されれば任意の複数枚とすることができる。傾斜羽根の数が少ない場合には、垂直吹出の際に抵抗が少なくなるといった点で都合が良く、一方、傾斜羽根の数が多い場合には、気流への旋回性の付与がより確実となり、逆に水平吹出に都合が良くなる。さらに、傾斜羽根の角度も、角度を大きくして垂直方向への速度成分を大きくし、垂直吹出に適するようにしたり、角度を小さくして水平方向への速度成分を大きくし、水平吹出に適するようにしたりなど、適宜調整を施すことができる。
【００３７】
また、前記第１及び第２の各実施の形態に係る吹出口装置においては、開口枠体の室内空間側開口端部は開放された構成としているが、これに対し、多数の開口孔を形成されてなる表装体、例えばパンチングメタル等を、開口枠体の開口端部を覆うように配設する構成とすることもでき、室内空間側から案内板並びに傾斜羽根が見えなくなり、天井面におけるデザイン的な統一感が保てると共に、気流が開口孔を通過する際に室内空間内空気との混合が促進され、空気調和能力が高まる。
【００３８】
また、前記第１及び第２の各実施の形態に係る吹出口装置においては、ネック部は略円筒形状に形成され、案内板も略円板体で形成される構成であるが、これに限らず、図７に示すように、ネック部３１を矩形筒状とし、これに合わせて案内板３３も矩形の略板状体とした構成とすることもでき、天井内のレイアウトや用途に合わせて適切な形状を選択できる。
【００３９】
さらに、前記第１及び第２の各実施の形態に係る吹出口装置においては、開口枠体は矩形の拡開状あるいは箱状に形成される構成であるが、これらに限らず、丸形の拡開状や箱状、筒状に形成する構成とすることもでき、用途、デザインに合わせて適切な形状を選択できる。
【００４０】
【発明の効果】
以上のように本発明においては、ネック部内側の案内板に傾斜羽根が放射状に複数配置され、各通風孔を通過する気流が傾斜羽根の所定の傾斜角度に沿って旋回流になると共に、案内板の中央開口部を開閉する閉塞蓋及び開閉手段が配設され、中央開口部に気流を通すか通さないかを切替えて開口枠体内での旋回流の挙動を変化させることにより、吹出す気流に偏流を生じさせずに各方向へ均等に吹出せ、且つ風量に関わりなく空気調和対象空間内空気への気流の混合・拡散が速くドラフトが生じにくいといった旋回流の性質を保持しつつ、開口枠体から吹出す気流の吹出パターンを例えば水平から垂直へと大きく変化させられることとなり、設置箇所や空気調和対象空間の状況に応じた空気調和が行え、空気調和能力が大幅に向上するという効果を奏する。
また、本発明においては、ネック部内側の案内板に傾斜羽根が放射状に複数配置され、各通風孔を通過する気流が傾斜羽根の所定の傾斜角度に沿って旋回流になると共に、案内板がネック部内で軸方向移動自在に配設され、ネック部内での案内板位置すなわち傾斜羽根位置を調整して開口枠体内での旋回流の挙動を変化させることにより、吹出す気流に偏流を生じさせずに各方向へ均等に吹出せ、且つ風量に関わりなく空気調和対象空間内空気への気流の混合・拡散が速くドラフトが生じにくいといった旋回流の性質を保持しつつ、開口枠体から吹出す気流の吹出パターンを例えば水平から垂直へと大きく変化させられることとなり、設置箇所や空気調和対象空間の状況に応じた空気調和が行え、空気調和能力が大幅に向上するという効果を有する。
また、本発明においては、案内板中心に中央開口部を形成すると共に閉塞蓋を開閉自在に配設し、案内板位置の調整に加えて中央開口部への気流の流通を切替可能として開口枠体内での旋回流の挙動を大幅に変化させられることにより、より多様な吹出パターンの変化を得られることとなり、状況に応じて最も効率的な吹出パターンを適宜選択することができ、空気調和能力をさらに向上させられるという効果を有する。
また、本発明においては、開口枠体がネック部の他端側開口との連設部分から急激に拡大し、且つ空気調和対象空間側端部まで所定寸法を確保した開口領域を有するように形成され、ネック部から出た旋回流が急拡大した開口枠体の内側隅部分に適度に生じる剥離域（負圧域）によって外周方向に導かれ、気流の向きを横向きに大きく湾曲させることにより、空気調和対象空間側開口から横向きに周囲各方向へ吹出せることとなり、他にコーン、遮閉板等の気流案内手段を用いずに気流の導入方向に対して略垂直な横向きの吹出を行うことができ、簡略化した構造として大幅なコストダウンが図れるという効果を有する。
また、本発明においては、傾斜羽根を略板状体である案内板の折曲げで一体に形成していることにより、取扱性に優れ、製造が容易でコストダウンを図れると共に、傾斜羽根の折曲の具合をそれぞれ調整することで通風孔を通過する気流の吹出角度の調整も容易に行え、傾斜羽根の角度変化で旋回流の状態を様々に得られ、空気調和対象空間側の環境条件に適切に対応でき、空気調和能力を高められるという効果を有する。
また、本発明においては、傾斜羽根及び案内羽根の縁部分に植毛を施すことにより、風切り音の発生を防ぐと共に、上流から伝播する音を吸収でき、空気調和対象空間側開口から漏れる騒音を減少させられるという効果を有する。

DETAILED DESCRIPTION OF THE INVENTION
(First embodiment of the present invention)
Hereinafter, the blower outlet apparatus concerning the 1st Embodiment of this invention is demonstrated based on FIGS. 1-3. 1 is a schematic longitudinal sectional view of a blowout device according to the present embodiment, FIG. 2 is a bottom view of the blowout device according to the present embodiment, and FIG. 3 is a blowout by the blowout device according to the present embodiment. State explanatory drawing is shown.
[0015]
As shown in the respective drawings, the air outlet device according to the present embodiment is arranged in the ceiling 50 and is connected to a duct 51 at one end side opening to be supplied with conditioned air, and has a substantially cylindrical neck portion 11. And an opening frame body 12 that is continuous with the opening at the other end of the neck portion 11 and has an opening region that communicates with the neck portion 11 and blows conditioned air into the indoor space, and is substantially the same as the inner diameter of the neck portion 11. The center opening 13a having a predetermined size is formed in the center portion, and a plurality of predetermined-shaped notches are formed radially at a predetermined pitch in the circumferential direction. Based on this cut, a plurality of predetermined portions of the substantially disc body are bent at a predetermined angle to be inclined to form a plurality of inclined blades 14, and an opening portion obtained by bending the inclined blades 14 is ventilated. As a hole 13b, in the vicinity of the other end side opening inside the neck portion 11 A guide plate 13 provided; a closing lid 15 provided so that the central opening 13a of the guide plate 13 can be freely opened and closed; one end portion is fixed to the neck portion 11; A temperature sensor 16 is provided that is fixedly disposed, expands and contracts according to the temperature of the conditioned air, and opens and closes the central opening 13a by moving the closing lid 15 up and down relative to the guide plate 13. .
[0016]
The opening frame body 12 is configured to be formed in a rectangular open shape in which a rectangular opening region of a portion connected to the opening on the other end side of the neck portion 11 expands toward the indoor space side. It is the structure which has a predetermined depth dimension from a part to the connection part with the neck part 11. FIG.
[0017]
The inclined blades 14 are configured such that the bent portions are arranged in the radial direction with respect to the guide plate 13 so that the airflow is blown out in the tangential direction of the guide plate 13 (see FIG. 2).
[0018]
Next, the blow-out operation in the blow-out device based on the above configuration will be described. The conditioned air sent from the duct 51 travels downward in the neck portion 11, and is guided obliquely downward in the tangential direction of the guide plate 13 along the inclination of each of the inclined blades 14 that are radially arranged, while the ventilation holes 13 b. Therefore, the airflows are combined on the downstream side of the guide plate 13 to form a swirl flow having a swirl velocity component along the inner wall of the neck portion 11.
[0019]
Here, in the case of heating, the temperature sensor 16 on the upstream side of the guide plate 13 extends due to warm air, acts to lower the closing lid 15 toward the guide plate 13, and the central opening 13a of the guide plate 13 is closed. The Thereby, warm air will pass only the ventilation hole 13b.
[0020]
The warm air advances downward through the opening frame 12 while keeping turning and blows downward into the indoor space. By blowing light warm air downward from the ceiling 50 as a swirling flow, the indoor air can be attracted and mixed by the swirling flow, and the heating effect can be reliably obtained up to the living area in a short time.
[0021]
On the other hand, in the case of cooling, the temperature sensor is contracted by the cold air, the closing lid 15 is raised with respect to the guide plate 13, and the central opening 13a of the guide plate 13 is opened. Thereby, cold air | gas reaches | attains below not only from the ventilation hole 13b but this center opening part 13a.
[0022]
Normally, the center of the swirling flow is in a state where the air current is stagnated and almost stopped and the pressure is low, and the swirling flow surrounds and rotates around the stagnant central portion. If the central opening 13a is opened so that the airflow passes from the upstream side, a downward airflow is generated in the central portion of the swirling flow and the pressure increases, so that the balance between the inside and outside of the swirling flow cannot be maintained. The flow spreads in the centrifugal direction and is blown sideways along the inner surface of the opening frame 12. Even if it becomes a sideways airflow, it can be blown out in each direction without deviation by the swirl component.
[0023]
Thus, the cold air is blown out substantially horizontally from the opening frame 12 to the indoor space. Cold air that is heavier than room air is blown out in the horizontal direction from the opening frame 12, and the indoor air can be strongly attracted and mixed, so that it can fully exhibit the diffusion performance regardless of the air volume and significantly enhance the cooling effect. The room can be cooled in a short time and no drafting occurs. Further, since the cool air can be blown out from the opening frame 12 in each direction, the dew condensation that has occurred in the corner portion that is difficult to blow out the cold air in the case of the conventional rectangular air outlet is reliably suppressed.
[0024]
Thus, in the blowout device according to the present embodiment, the neck portion 11 has a substantially circular cross section, the inclined blades 14 are arranged radially on the guide plate 13, and the swirl flows along the inclination of each inclined blade 14. In addition, the opening and closing of the central opening 13a at the center of the guide plate 13 is switched to switch between horizontal blowing and vertical blowing, so that a blowing pattern corresponding to the conditioned air temperature can be selected while taking advantage of the effect of attracting and diffusing the swirling flow This will greatly improve the air conditioning capability.
[0025]
(Second embodiment of the present invention)
The blower outlet apparatus which concerns on the 2nd Embodiment of this invention is demonstrated based on FIGS. 4 is a schematic longitudinal sectional view of the blowout device according to the present embodiment, FIG. 5 is a bottom view of the blowout device according to the present embodiment, and FIG. 6 is a blowout by the blowout device according to the present embodiment. State explanatory drawing is shown.
[0026]
As shown in the drawings, the air outlet device according to the present embodiment includes a neck portion 21, an opening frame body 22, a guide plate 23, and inclined blades 24, as in the first embodiment. On the other hand, as a different configuration, the shape of the opening frame 22 is a rectangular box shape that is suddenly enlarged from the position where it is connected to the neck portion 21, and the central opening is omitted from the guide plate 23 as a position adjusting means. The temperature sensor 25 directly moves the guide plate 23 up and down.
[0027]
The guide plate 23 is disposed in the vicinity of the opening on the other end side of the neck portion 21 via the temperature sensor 25 so as to be movable up and down within a predetermined range, and moves up and down with respect to the neck portion 21 as the temperature sensor 25 expands and contracts. It is a mechanism.
[0028]
Next, the blow-out operation in the blow-out device based on the above configuration will be described. As in the first embodiment, the conditioned air sent from the duct 51 travels downward in the neck portion 21 and is obliquely tangential to the guide plate 23 along the inclination of the inclined blades 24 arranged radially. Since the air passes through the ventilation holes 23a while being guided downward, the airflows are combined on the downstream side of the guide plate 23 to form a swirl flow having a swirl velocity component along the inner wall of the neck portion 21.
[0029]
Here, in the case of heating, the temperature sensor 25 on the upstream side of the guide plate 23 is extended by the warm air and acts to raise the guide plate 23, and the guide plate 23 is separated from the opening on the other end side of the neck portion 21. Become. The warm air passes through the vent hole 23a of the raised guide plate 23, reaches the opening frame body 22 while keeping turning along the inner wall of the neck portion 21, and blows downward from the opening frame body 22 into the indoor space. As in the first embodiment, by blowing light warm air downward from the ceiling 50 as a swirling flow, the indoor air can be attracted and promoted by the swirling flow, and the heating effect can be reliably achieved in a short time. can get.
[0030]
On the other hand, in the case of cooling, the temperature sensor is contracted by the cold air, and the guide plate 23 is lowered to be positioned in the vicinity of the opening on the other end side of the neck portion 21.
[0031]
The airflows that have passed through the ventilation holes 23a along the inclined blades 24 are combined along the inner wall of the neck portion 21 to form a swirl flow having a swirl velocity component. However, when the guide plate 23 is lowered, the ventilation holes Since the length of the neck portion 21 along the passage of 23a is not sufficient, the flow cannot be sufficiently developed as a swirling flow, and a velocity component that tries to flow in the direction along the inclined blade 24 into the opening frame body 22 remains.
[0032]
In the flow from the neck portion 21 to the opening frame body 22, since the continuous portion is rapidly expanded, separation occurs in the flow, and a separation area occurs in the inner corner of the opening frame body 22. In the case of heating, the swirling flow is sufficiently developed by placing the guide plate 23 in the upper position, and the separated flow does not reattach to the inner wall of the opening frame 22, and the swirling flow blows downward as it is. In this case, since the swirling flow is not developed, the swirling flow spreads in the centrifugal direction, the flow itself is greatly bent laterally along the separation region, and the separated flow is reattached to the inner wall of the opening frame 22. As a result, the airflow is blown sideways from the opening frame 22 as it is. Even if it becomes a sideways airflow, it can be blown out in each direction by the swirl component of the flow.
[0033]
Thus, the cold air is blown out substantially horizontally from the opening frame 22 into the indoor space. Cold air that is heavier than room air is blown out in the horizontal direction from the opening frame 22 and the indoor air can be strongly attracted and mixed, so that it can fully exhibit the diffusion performance regardless of the air volume and significantly enhance the cooling effect. The room can be cooled in a short time and no drafting occurs. Further, as in the first embodiment, since cold air can be blown out from the opening frame body 22 in each direction, the dew condensation that has occurred in the corner portion that is difficult to blow out the cold air in the case of the conventional rectangular air outlet is also ensured. It can be suppressed.
[0034]
Thus, in the blowout device according to the present embodiment, the neck portion 21 has a substantially circular cross section, the inclined blades 24 are arranged radially on the guide plate 23, and the swirl flows along the inclination of the inclined blades 24. In addition, the position within the neck portion 21 of the guide plate 23 is switched, and the horizontal blowing and the vertical blowing are switched, so that a blowing pattern more suitable for the conditioned air temperature can be selected while utilizing the effect of attracting and diffusing the swirling flow, Air conditioning capability will be greatly improved.
[0035]
In the air outlet device according to the embodiment, the center of the guide plate 23 is closed. However, similarly to the first embodiment, the center of the guide plate 23 has a predetermined size. And a temperature sensor that opens and closes the central opening by moving the closing lid up and down with respect to the guide plate 23. The blowing pattern can be changed in a complicated manner by adjusting the position of the guide plate 23 and opening and closing the central opening. For example, if the central opening is opened when the guide plate 23 is in the lower position, the horizontal blowout is the same as in the closed state. However, if the central opening is opened when the guide plate 23 is in the upper position, the vertical blowout is performed. The swirling flow spreads more in the centrifugal direction and becomes a swirling flow having a wider width, and attraction and mixing of room air is promoted, and the air conditioning effect can be obtained in a shorter time.
[0036]
Further, in the blowout device according to each of the first and second embodiments, the inclined blades on the guide plate are not limited to the number shown in the respective drawings, and may be arbitrary as long as they are arranged at an equal pitch in the circumferential direction. It can be a plurality of sheets. When the number of inclined blades is small, it is convenient in that the resistance decreases during vertical blowing, while when the number of inclined blades is large, it is more reliable to impart swirlability to the airflow, On the contrary, it becomes convenient for horizontal blowing. In addition, the angle of the inclined blades is also increased to increase the velocity component in the vertical direction to be suitable for vertical blowing, or the angle is decreased to increase the velocity component in the horizontal direction to be suitable for horizontal blowing. Adjustments can be made as appropriate.
[0037]
Moreover, in the blower outlet apparatus which concerns on the said 1st and 2nd embodiment, although the indoor space side opening edge part of the opening frame is made into the open structure, many opening holes are formed with respect to this It is also possible to use a structure such as a punching metal that covers the opening end of the opening frame so that the guide plate and the inclined blades cannot be seen from the indoor space side, and the design on the ceiling surface A sense of unity can be maintained, and mixing with the air in the indoor space is promoted when the airflow passes through the opening hole, so that the air conditioning capability is enhanced.
[0038]
Moreover, in the blower outlet apparatus which concerns on the said 1st and 2nd embodiment, although a neck part is formed in a substantially cylindrical shape and a guide plate is also formed in a substantially disc body, it is not restricted to this. First, as shown in FIG. 7, the neck portion 31 is formed in a rectangular cylindrical shape, and the guide plate 33 can be configured to be a substantially rectangular plate-like body in accordance with this. An appropriate shape can be selected.
[0039]
Furthermore, in the blowout device according to each of the first and second embodiments, the opening frame is configured to be formed in a rectangular expanded shape or box shape, but is not limited thereto, and is not limited to a round shape. It can also be set as the structure formed in an expanded shape, a box shape, and a cylinder shape, and an appropriate shape can be selected according to a use and a design.
[0040]
