【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する床面あるいは壁面から突出させて配設され、前記空気調和対象空間への空気調和用気体の吹出方向を温度に応じて変化させ、前記気体を空気調和対象空間内の所定箇所に適切に到達させられる吹出口装置に関する。
【０００２】
【従来の技術】
空気調和の対象となる室内空間に面して配設され、ダクトを通じて供給される調和空気を吹出す吹出口装置においては、前記室内空間が大きい場合、従来は調和空気の到達距離を大きくとれるノズル型の吹出口装置が一般的に用いられていた。このようなノズル型の吹出口装置においては、近年、調和空気の温度に応じて吹出方向を変化させられるものが使用されるようになっている。従来のこのようなノズル型の吹出口装置を図１２に示す。この図１２は従来の吹出口装置の概略構成断面図である。
【０００３】
前記図１２において従来の吹出口装置１００は、壁５０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略円筒状の吹出口本体１０１と、この吹出口本体１０１の開口領域内側に傾動自在に配設される略円筒体の気流案内部１０２と、前記吹出口本体１０１と気流案内部１０２との間に配設され、吹出口本体１０１に対して気流案内部１０２を所定角度に傾動させるアクチュエータ１０３とを備える構成である。
【０００４】
前記アクチュエータ１０３は、周囲の気流の温度変化に対応してセンサ本体１０３ａからのニードル１０３ｂの突出し量を変化させる方式の温度センサを有し、ニードル１０３ｂを吹出口本体１０１側に、センサ本体１０３ａを気流案内部１０２側にそれぞれ取付けると共に、センサ本体１０３ａに対しニードル１０３ｂを押込む方向に付勢させるスプリング１０３ｃを配設されてなる構成である。
【０００５】
上記した構成の従来の吹出口装置１００においては、調和空気の温度に応じたアクチュエータ１０３の作用により気流案内部１０２が動き、吹出口本体１０１に対する角度を調整される。冷房の場合には、冷気に当ったセンサ本体１０３ａがスプリング１０３ｃの付勢によりニードル１０３ｂを引込んで突出し量を小さくし、吹出口本体１０１に対し気流案内部１０２の角度を起し、冷気をそのまま横方向に吹出させて室内に分散させる。
【０００６】
一方、暖房の場合には、暖気に当ったセンサ本体１０３ａがニードル１０３ｂを押出して突出し量を大きくすることにより、吹出口本体１０１に対し気流案内部１０２の角度を傾け、軽い暖気を斜め下向きに吹出して暖気がより下方まで達して室内空間全体を効率的に暖められるようにしている。
【０００７】
【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、ノズル型の吹出口装置を配設する空気調和対象の室内空間が、劇場やホール、アリーナ等の大きな空間領域である場合、床面付近や観客席等といった人々の活動域まで均等に空気調和を行うためには、調和空気と室内空気との混合期間が十分にとれるように壁面上方や天井に吹出口を配設し、且つ吹出口から大風量の気流を吹出す必要があり、このために各吹出口に通じるダクト等の付帯設備が空間の大きい分大規模なものとなり、その配設が困難になるという問題がある。特に、冷房の場合で、冷気の下降作用を最大限利用して確実に前記活動域まで冷気を到達させるために天井付近に吹出口及びダクトを配設しようとすると、ダクト設備が著しく長経路となってしまい、設置作業の困難さと合わせ、コスト高を招くばかりでなく、暖房の場合に上昇する性質を有する暖気を適切に下方の活動域に到達させることができないという課題を有した。また、アリーナ等、採光のために上部構造がガラス等の透光性素材で覆われた造りとなっている場合、この部分に吹出口設置が行えないため、より下方に吹出口を配設した構造を採らざるを得ず、室内に均等に空気調和を行うことが難しくなるという課題を有した。
【０００８】
本発明は前記課題を解消するためになされたもので、コンパクトで設置の制約が少なく、活動域近傍に配設可能として空気調和設備の大規模化を防げると共に、気流の吹出方向を気流温度によって変化させられ、気流の十分な到達距離を確保でき、空気調和対象空間で一様且つ確実に空気調和が行える吹出口装置を提供することを目的とする。
【０００９】
【課題を解決するための手段】
本発明に係る吹出口装置は、一端部から空気調和用の気体が供給される所定長さの略筒状体で形成され、当該略筒状体の他端部が閉塞されると共に前記他端部から所定寸法離れた周側面に開口部を形成されてなり、前記他端部側を空気調和の対象空間内に突出させて配設され、前記空気調和用気体を前記開口部から前記空気調和対象空間へ吹出す吹出口本体と、当該吹出口本体内部における前記一端部と前記開口部との中間位置に配設され、吹出口本体内側面に沿って吹出口本体内部の開口領域の一部を閉塞又は開放する吹出方向調整手段とを備え、当該吹出方向調整手段として、前記吹出口本体一端部寄りの前記開口部縁部と同じ筒軸方向位置で吹出口本体の筒軸方向と略垂直をなして吹出口本体内部の開口領域を一部閉塞する気流案内板と、当該気流案内板の端部に一辺が蝶着される略板状体で形成され、前記吹出口本体の開口領域内側で所定角度回動自在に配設される風向調整板と、前記気流案内板及び風向調整板の間に配設され、前記風向調整板を気流案内板に対し所定角度に保持する角度調節手段とを有するものである。
このように本発明によれば、空気調和対象空間内に突出する吹出口本体の内部に吹出方向調整手段を配設し、吹出方向調整手段で吹出口本体内部の開口領域を変化させ、吹出口本体内での気流速度を変化させて開口部から出る気流の吹出方向を複数通りに変化させられることにより、外部に気流を制御するための突出物等がない単純なポール状の外観を呈して、吹出口としての機械的な印象を与えにくく且つコンパクトにでき、違和感を与えずに室内デザインの一部に溶け込ませて活動域近傍に配置可能とし、加えて、気流の吹出方向を適切に調整して活動域近傍からでも気流を確実に活動域へ到達させられることとなり、空気調和設備の天井や壁面上部への配設を不要として大規模設備化を防ぎ、コストダウンを図れる。さらに、突出した吹出口本体の周側部に開口部が配設されて、吹出した気流に対し開口部側方及び後方からも前記空間内の空気の誘引が生じることにより、吹出気流への誘引空気量を多くとれることとなり、前記空間内空気との混合を速くして空気調和が短時間に行える。
【００１０】
加えて、吹出方向調整手段として気流案内板、風向調整板及び角度調節手段を配設し、風向調整板の向き及び風向調整板と吹出口本体内面との間隔を変化させて、開口部から気流を複数の所定方向へ切替え可能に吹出せることにより、気流の吹出方向を気流温度によって変化させて十分な到達距離を確保でき、活動域近傍からでも気流を確実に活動域へ均一に到達させられる。
【００１１】
また、本発明に係る吹出口装置は必要に応じて、前記吹出口本体が、前記開口部を含む他端側の所定寸法範囲部分と残りの一端側部分とをそれぞれ別々に独立させた略円筒体で形成され、前記他端側部分を前記一端側部分に対し略円筒体周方向へ回動自在に連結してなるものである。このように本発明によれば、吹出口本体の他端側部分と一端側部分を別体として配設し、他端側部分を一端側部分に対して回動させて開口部位置を変化させられることにより、気流の吹出方向を吹出口本体周囲の所定方向に自在に切替えられ、用途に応じて吹出方向を切替えて様々な状況に対応した空気調和が行える。
【００１２】
また、本発明に係る吹出口装置は必要に応じて、前記気流案内板が、前記吹出口本体一端部寄りの前記開口部縁部に近接して配設されるものである。このように本発明によれば、気流案内板を開口部縁部に近接させて配設し、風向調整板の向きを変えて、気流の吹出口本体内挙動を変化させ、開口部より他端部側の吹出口本体内への気流の流れ込みの有無を切替えることにより、気流を気流案内板に沿わせてそのまま開口部正面方向へ吹出させたり、気流を一度吹出口本体内他端部側に送込んで反転させ、開口部から斜め方向へ吹出させたりすることが切替え可能に行え、気流温度に応じて吹出方向を切替えて十分な気流の到達距離が得られる。
【００１３】
また、本発明に係る吹出口装置は必要に応じて、前記気流案内板が、前記吹出口本体一端部寄りの前記開口部縁部に対向する吹出口本体内側面位置に沿って配設されるものである。このように本発明によれば、気流案内板を開口部縁部から最も離れた対向位置に配設し、風向調整板の向きを変えて、気流の開口部直前での流れ状態を変化させることにより、気流をそのまま開口部正面方向へ吹出させたり、気流の吹出口本体他端部側へ向う速度成分を増大させて、開口部から斜め方向へ吹出させたりすることが切替え可能に行え、気流温度に応じて吹出方向を切替えて十分な気流の到達距離が得られる。
【００１４】
また、本発明に係る吹出口装置は、一端部から空気調和用の気体が供給される所定長さの略筒状体で形成され、当該略筒状体の他端部が閉塞されると共に前記他端部から所定寸法離れた周側面に開口部を形成されてなり、前記他端部側を空気調和の対象空間内に突出させて配設され、前記空気調和用気体を前記開口部から前記空気調和対象空間へ吹出す吹出口本体と、当該吹出口本体内部における前記一端部と前記開口部との中間位置に配設され、吹出口本体内側面に沿って吹出口本体内部の開口領域の一部を閉塞又は開放する吹出方向調整手段とを備え、当該吹出方向調整手段として、前記吹出口本体の内側に内接する径の略円筒体で形成され、当該略円筒体の少なくとも周側面の一部を含む所定位置に開口孔を形成され、当該開口孔が前記吹出口本体の開口部に連通可能な吹出口本体内側の所定位置で吹出口本体に対し周方向回動自在に保持されてなる吹出ガイド筒と、当該吹出ガイド筒の開口孔の前記吹出口本体一端部側寄り縁部と同じ筒軸方向位置で吹出ガイド筒の筒軸方向と略垂直をなして吹出ガイド筒内部を一部閉塞する気流案内板と、当該気流案内板の端部に一辺が蝶着される略板状体で形成され、前記吹出ガイド筒内の開口領域で所定角度回動自在に配設される風向調整板と、前記気流案内板及び風向調整板の間に配設され、前記風向調整板を気流案内板に対し所定角度に保持する角度調節手段とを有するものである。
このように本発明によれば、吹出方向調整手段として吹出ガイド筒、気流案内板、風向調整板及び角度調節手段を配設し、風向調整板の向き及び風向調整板と吹出ガイド筒内面との間隔を変化させて、開口孔から開口部を介して気流を複数の所定方向へ切替え可能に吹出せることにより、気流の吹出方向を気流温度によって変化させて十分な到達距離を確保でき、活動域近傍からでも気流を確実に活動域へ均一に到達させられる。さらに、吹出ガイド筒を吹出口本体に対して回動させて開口部における開口孔位置を変化させられることにより、気流の吹出方向を開口部の範囲内で自在に切替えられ、用途に応じて吹出方向を切替えて様々な状況に対応した空気調和が行える。
【００１５】
また、本発明に係る吹出口装置は必要に応じて、前記角度調節手段が、一端部を前記気流案内板に固定され、他端部を前記風向調整板に固定されて配設され、吹出す空気調和用気体の温度に応じて自動的に伸縮して前記一端部と他端部との間隔を変化させ、気流案内板に対し風向調整板を所定角度に傾動させるアクチュエータであるものである。このように本発明によれば、気流案内板と風向調整板との間にアクチュエータを配設し、気流の温度変化に応じたアクチュエータの伸縮で風向調整板が自動的に傾動して開口部からの気流吹出方向を変化させられることにより、作業者による吹出方向の調整がほとんど不要となり、調整の手間が省ける。
【００１６】
【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について、図１〜図６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斜視図、図２は本実施の形態に係る吹出口装置の横断面図及び一部省略正面図、図３は本実施の形態に係る吹出口装置の要部底面図、図４は本実施の形態に係る吹出口装置の温度センサの状態説明図、図５は本実施の形態に係る吹出口装置の一部省略縦断面図、図６は本実施の形態に係る吹出口装置の吹出状態説明図である。
【００１７】
前記各図において本実施の形態に係る吹出口装置１０は、金属製の円筒外殻内部に断熱材としてグラスウール層を配した中空筒体として形成され、周側面に方形状開口断面の開口部１１ａを形成されてなり、室内空間の床（図示を省略）から垂直上方に突設される吹出口本体１１と、前記開口部１１ａ近傍の吹出口本体１１内開口領域を一部閉塞するように配設される気流案内板１２と、前記吹出口本体内の開口領域で端部を気流案内板１２に一体に蝶着させて傾動自在に配設される風向調整板１３と、一端部を前記気流案内板１２に固定され、他端部を前記風向調整板１３に固定されて配設され、調和空気の温度に応じて伸縮し、気流案内板１２に対し風向調整板１３を傾動させるアクチュエータとしての温度センサ１４とを備える構成である。
【００１８】
前記吹出口本体１１は、床からの高さが活動域より高い位置となるような長さの中空筒体で、下端部を床に固定され、閉塞されている上端部から所定長さ離れた周側面に室内側へ向けて調和空気を送出す開口部１１ａが穿設され、床の内側で下端部がダクト（図示を省略）に接続されて調和空気を取込み、この調和空気を開口部１１ａから室内空間へ吹出す構成である。また、この吹出口本体１１の開口部１１ａには、ここから吹出口本体１１内部に異物が進入しないよう、開口率の高いカバー１１ｂが配設される。
【００１９】
前記気流案内板１２は、吹出口本体１１内面に密着する円弧部分を有する板状体に形成され、前記吹出口本体１１内の開口領域に面する端部に前記風向調整板１３を軸支する蝶番部１２ａを二つ配設され、開口領域のうち開口部１１ａ近傍部分を一部塞いで配設される構成である。
【００２０】
前記風向調整板１３は、略方形の板状体に形成され、端部を前記気流案内板１２の蝶番部１２ａに固着されて気流案内板１２と一体化させて吹出口本体１１の内側へ傾動自在に配設され、前記気流案内板１２に対する角度を変化させて気流の吹出の向きを変化させる構成である。
【００２１】
前記アクチュエータをなす温度センサ１４は、周囲の雰囲気温度の変化に対応してセンサ本体１４ａからのニードル１４ｂの突出量を変化させるものであり、二つのセンサ本体１４ａが、一つのニードル１４ｂの両端で互いに対向する状態で配置されてなり、一端側のセンサ本体１４ａを気流案内板１２の下面に配設された支持部材１２ｂの一端部に固定し、他端側のセンサ本体１４ａを風向調整板１３から突設された取付部材１３ａに補助部材１４ｃを介して回動自在且つ遊貫状態で軸着して配設される構成である。これに加えて、他端側のセンサ本体１４ａと前記支持部材１２ｂの他端部との間にスプリング１５が配設され、センサ本体１４ａ同士が互いに近づく向きに付勢される仕組みとなっている。
【００２２】
これらの温度センサ１４が、気流温度によるニードル１４ｂの突出量の変化によってセンサ本体１４ａ間の距離を変え、最も伸びた位置では風向調整板１３を気流案内板１２に対し一連に並ぶ水平向きに、最も縮んだ位置では風向調整板１３を気流案内板１２に対し垂直をなす向きに変化させる。ただし、気流案内板１２と風向調整板１３が一続きで略水平に並んだ状態で吹出口本体１１内部を塞ぐ領域は、吹出口本体１１の開口領域横断面の半分以下となっている。
【００２３】
次に、前記構成に基づく吹出口装置における気流吹出動作について説明する。冷房の場合、ダクトから送られた冷気が吹出口本体１１に入ると、冷気に当って温度センサ１４の各センサ本体１４ａがニードル１４ｂをそれぞれ引込んで互いの間隔を縮め、風向調整板１３を気流案内板１２に対し下方に傾動させ、気流案内板１２に対して風向調整板１３を略垂直向きとする。これにより、風向調整板１３と吹出口本体１１内面との間の通路断面積が広がった状態となる。冷気は、この風向調整板１３と吹出口本体１１内面との間の通路部分を通り、気流速度をほとんど変化させずに、気流案内板１２に沿って開口部１１ａからそのまま正面の略水平向きに室内に吹出す。室内の空気より重い冷気を活動域より高い位置にある開口部１１ａから水平方向に吹出すことで、活動域に達するまでに十分室内に拡散させられ、ドラフトを生じさせずに、室内空気の冷却効果が大きく、短時間に室内を冷すことができる。
【００２４】
一方、暖房の場合は、ダクトから送られた暖気が吹出口本体１１内に入ると、暖気に当って温度センサ１４の各センサ本体１４ａがニードル１４ｂをそれぞれ押出して互いの間隔を広げ、気流案内板１２に対して風向調整板１３を冷房時と逆に上方へ回動させ、気流案内板１２と一続きの略水平向きとする。これにより、風向調整板１３と吹出口本体１１内面との間の通路断面積が狭くなる。暖気は、吹出口本体１１内を上向きに進み、この風向調整板１３と吹出口本体１１内面との間の狭くなった通路部分を通ることで気流速度を上げ、その勢いでいったん吹出口本体１１内の上部に達する。吹出口本体１１他端部から開口部１１ａまでの長さを適宜確保していることにより、この吹出口本体１１内の上部から、開口部１１ａに向って気流が反転して下向きの速度成分を得ることとなり、気流は開口部１１ａから斜め下向きに室内に吹出す。室内の空気より軽い暖気を活動域より高い位置にある開口部１１ａから斜め下向きに吹出すことで、確実に活動域まで到達させられ、室内の空気の温度を上げる効果が大きく、短時間に室内を暖めることができる。
【００２５】
また、冷暖いずれの場合においても、吹出した気流は室内空気を誘引するが、開口部１１ａの前方のみならず、開口部１１ａの左右後方の空気も誘引することができ、室内空気との混合が急速に進行して空気調和効果を短時間で発揮でき、活動域に一様に空気調和効果を与えられる。
【００２６】
このように、本実施の形態に係る吹出口装置では、床から広い室内空間内に突出する吹出口本体１１の内部に気流案内板１２及び風向調整板１３を配設し、風向調整板１３の向き及び風向調整板１３と吹出口本体１１内面との間隔を変化させて、所定高さ位置の開口部１１ａから気流を開口部１１ａ正面方向又は斜め下方向へ切替え可能に吹出せることから、単純でコンパクトなポール状の外観を呈して、室内デザインの一部に違和感なく溶け込ませられ、また気流の吹出方向を気流温度によって変化させて十分な到達距離を確保できることとなり、活動域近傍に配置して空気調和設備全体の小規模・低コスト化が図れる。さらに、突出した吹出口本体１１の周側部に開口部１１ａが配設されて、吹出した気流に対し開口部１１ａ側方及び後方からも室内空気の誘引が生じることにより、吹出気流への誘引空気量を多くとれ、室内空気との混合を速くして空気調和効率の向上も図れる。加えて、筒体内部が断熱材製のため、冷房の場合でも筒体外面に結露を生じにくい。
【００２７】
なお、前記実施の形態に係る吹出口装置において、温度センサ１４は、センサ本体１４を二段に配設して温度変化に対し二倍のストロークを得て、風向調整板１３の回動変位に対応させる構成としているが、風向調整板１３の変位が少なくて済む場合には、温度センサ１４を一つだけ用いた構成とすることもできる。
【００２８】
（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について、図７に基づいて説明する。この図７は本実施の形態に係る吹出口装置の一部省略縦断面図である。
前図において本実施の形態に係る吹出口装置２０は、前記第１の実施の形態と同様、吹出口本体２１と、気流案内板２２と、風向調整板２３と、温度センサ２４とを備え、異なる点として、気流案内板２２を吹出口本体２１の開口部２１ａから最も離れた対向位置に配設し、この気流案内板２２に端部を一体に蝶着させて風向調整板２３を傾動自在に配設する構成を有するものである。
【００２９】
次に、前記構成に基づく吹出口装置における気流吹出動作について説明する。冷房の場合は、気流案内板２２に対して風向調整板２３を上方へ回動させて気流案内板２２と一続きの略水平向きとすると共に、風向調整板２３と吹出口本体２１内面との間の通路断面積が狭くなった状態とし、この狭くなった通路部分を通すことで冷気の気流速度を上げ、その勢いで開口部２１ａに向って上向きの速度成分を増大させ、開口部２１ａから斜め上向きに室内に吹出させる。一方、暖房の場合は、風向調整板２３を気流案内板２２に対し冷房時と逆に下方に傾動させて略垂直向きとすると共に、風向調整板２３と吹出口本体２１内面との間の通路断面積が広がった状態として、暖気の気流速度をほとんど変化させずに風向調整板２３と吹出口本体２１内面との間の通路部分を通過させ、気流案内板２２に沿って開口部２１ａからそのまま正面の略水平向きに室内に吹出させる。
【００３０】
このように、冷気を斜め上方向へ、暖気を開口部正面方向へそれぞれ吹出すこととなり、吹出口本体の高さが活動域に対して前記実施の形態の場合より低い位置である場合にも気流の十分な到達距離を確保できる。
【００３１】
（本発明の第３の実施の形態）
本発明の第３の実施の形態に係る吹出口装置について、図８に基づいて説明する。この図８は本実施の形態に係る吹出口装置の概略構成斜視図である。
前図において本実施の形態に係る吹出口装置３０は、前記第１の実施の形態と同様、吹出口本体３１と、気流案内板３２と、風向調整板３３と、温度センサ３４とを備え、異なる点として、吹出口本体３１が開口部３１ａを含む所定寸法範囲の上部本体３１ｂと下部本体３１ｃとの組合わせで形成され、上部本体３１ｂと下部本体３１ｃとを互いに回動自在に連結してなる構成を有するものである。
【００３２】
本実施の形態に係る吹出口装置においては、固定した下部本体３１ｃに対し上部本体３１ｂを回動させることにより、開口部３１ａの向きを自由に変化させられることとなり、用途に応じて吹出口本体３１周囲の所定方向に開口部３１ａを向けて気流を吹出させることができ、周囲の環境や設備等の変化にも柔軟に対応できる。
【００３３】
（本発明の第４の実施の形態）
本発明の第４の実施の形態に係る吹出口装置について、図９に基づいて説明する。この図９は本実施の形態に係る吹出口装置の一部省略正面図及び一部省略縦断面図である。
【００３４】
前図において本実施の形態に係る吹出口装置４０は、前記第１の実施の形態と同様、吹出口本体４１と、気流案内板４３と、風向調整板４４と、温度センサ４５とを備え、異なる点として、上部の所定位置に開口孔４２ａを穿設された略円筒体で形成され、前記吹出口本体４１内部で吹出口本体４１に対し周方向回動自在に保持されてなる吹出ガイド筒４２を備え、この吹出ガイド筒４２内部に前記気流案内板４３と風向調整板４４、及び温度センサ４５が配設されると共に、吹出口本体４１の開口部４１ａが周側部全周にわたって形成される構成を有するものである。
【００３５】
前記吹出ガイド筒４２は、前記吹出口本体４１の内側に内接する径で且つ上部を一部湾曲させて閉塞した略円筒体で形成され、この略円筒体の周側面の一部を含む上部の所定位置に開口孔４２ａを形成され、この開口孔４２ａが吹出口本体４１の開口部４１ａと連通可能な吹出口本体４１内側の所定位置で回動自在に保持されてなる構成である。この吹出ガイド筒４２内部に、気流案内板４３が開口孔４２ａ下縁近傍の吹出ガイド筒４２内開口領域を一部閉塞するように配設される構成である。
【００３６】
本実施の形態に係る吹出口装置においては、吹出口本体４１に対し内部の吹出ガイド筒４２を回動させることにより、気流を吹出す開口孔４２ａの向きを自由に変化させられることとなり、用途に応じて吹出口本体４１周囲の所定方向に開口孔４２ａを向けて気流を吹出させることができ、周囲の環境や設備等の変化にも柔軟に対応できる。
【００３７】
なお、前記第１〜第４の各実施の形態に係る吹出口装置においては、吹出口本体を円筒体とする構成としたが、方形、矩形など他の断面形状の筒体とする構成とすることもできる。また、吹出口本体の開口部も、方形状の他、円形や楕円形など別の開口断面形状とすることができる。さらに、開口部のカバーも格子のパターンを変えて、縦方向の細幅の板状体を所定間隔で複数放射状に配置すると共に横方向の丸棒材を取除いた構成とすることもでき、丸棒材を減らすことで斜め下方向への気流に対し抵抗を少なくし、気流をよりスムーズに吹出せる上、放射配置した縦方向の板状体で横方向に広がりのある吹出パターンが得られることとなる。
【００３８】
また、前記第１〜第４の各実施の形態に係る吹出口装置において、吹出口本体下部は単純な円筒構造にする構成としているが、この他、図１０に示すように、吹出口本体６１下部を二重円筒構造にする構成としてもよく、内側の円筒６１ｂ内を吹出気流の通路として確保した上で、外側の円筒６１ａに吸込口６１ｃを設け、内外の円筒間を吸込んだ室内空気の還流路に用いたりすることができ、装置の外観形状をほとんど変化させずに様々な用途に対応させられる。
【００３９】
また、図１１に示すように、開口部７１ａを吹出口本体７１の上端近傍及び上端面に配設すると共に、上下動する上端部材７２を配設し、この上端部材７２に間接照明器具としてランプ７３及び傘７４を取付ける構成とすることもでき、照明と併用して多目的に利用できる。吹出気流は、上端部材７２を上昇させると斜め下向きとなり（図１１（Ｂ）参照）、上端部材７２を下げると水平向きとなる（図１１（Ｃ）参照）。
【００４０】
また、前記第１〜第４の各実施の形態に係る吹出口装置において、温度センサとしては、水冷式エンジン（特に自動車用）のサーモスタットに一般的に使用されるものと同様の、固体あるいは液体のワックスをセンサ本体とニードル間に封入し、周囲温度の変化に対応してワックスの固体（液体）膨張及び、固体から液体への相変化に伴う膨張によりセンサ本体からのニードルの突出量を変化させる方式の温度センサで、且つニードルの移動し始めが約１７℃、全突出時が約２５℃となるようワックスを選定したものを使用する構成であるが、所定の設定温度範囲において所定長さ範囲で伸縮するものであれば、他の形式のもの、例えば、形状記憶合金を使用した温度センサを採用する構成とすることもできる。そして、温度センサの動作に関する各設定温度は、前記に限定したものではなく、空気調和条件に応じて任意に設定できる。

また、本発明においては、吹出口本体の他端側部分と一端側部分を別体として配設し、他端側部分を一端側部分に対して回動させて開口部位置を変化させられることにより、気流の吹出方向を吹出口本体周囲の所定方向に自在に切替えられ、用途に応じて吹出方向を切替えて様々な状況に対応した空気調和が行えるという効果を有する。
また、本発明においては、気流案内板を開口部縁部に近接させて配設し、風向調整板の向きを変えて、気流の吹出口本体内挙動を変化させ、開口部より他端部側の吹出口本体内への気流の流れ込みの有無を切替えることにより、気流を気流案内板に沿わせてそのまま開口部正面方向へ吹出させたり、気流を一度吹出口本体内他端部側に送込んで反転させ、開口部から斜め方向へ吹出させたりすることが切替え可能に行え、気流温度に応じて吹出方向を切替えて十分な気流の到達距離が得られるという効果を有する。
また、本発明においては、気流案内板を開口部縁部から最も離れた対向位置に配設し、風向調整板の向きを変えて、気流の開口部直前での流れ状態を変化させることにより、気流をそのまま開口部正面方向へ吹出させたり、気流の吹出口本体他端部側へ向う速度成分を増大させて、開口部から斜め方向へ吹出させたりすることが切替え可能に行え、気流温度に応じて吹出方向を切替えて十分な気流の到達距離が得られるという効果を有する。
また、本発明においては、吹出方向調整手段として吹出ガイド筒、気流案内板、風向調整板及び角度調節手段を配設し、風向調整板の向き及び風向調整板と吹出ガイド筒内面との間隔を変化させて、開口孔から開口部を介して気流を複数の所定方向へ切替え可能に吹出せることにより、気流の吹出方向を気流温度によって変化させて十分な到達距離を確保でき、活動域近傍からでも気流を確実に活動域へ均一に到達させられるという効果を有する。さらに、吹出ガイド筒を吹出口本体に対して回動させて開口部における開口孔位置を変化させられることにより、気流の吹出方向を開口部の範囲内で自在に切替えられ、用途に応じて吹出方向を切替えて様々な状況に対応した空気調和が行えるという効果を有する。

BACKGROUND OF THE INVENTION
The present invention is disposed so as to protrude from a floor surface or a wall surface facing a space to be air-conditioned, and changes the direction of blowing the air-conditioning gas to the air-conditioning target space according to the temperature. It is related with the blower outlet apparatus which can be appropriately made to reach | attain the predetermined location in air conditioning object space.
[0002]
[Prior art]
In a blowout device that is arranged facing an indoor space that is subject to air conditioning and blows out conditioned air supplied through a duct, when the indoor space is large, a nozzle that can conventionally increase the reach of conditioned air A type air outlet device was commonly used. In such nozzle-type air outlet devices, those that can change the air outlet direction in accordance with the temperature of the conditioned air have been used in recent years. FIG. 12 shows such a conventional nozzle-type air outlet device. FIG. 12 is a schematic cross-sectional view of a conventional outlet device.
[0003]
In FIG. 12, the conventional blower outlet device 100 is disposed on a wall 50 and is connected to a duct 51 to be supplied with conditioned air. A substantially cylindrical airflow guide portion 102 that is tiltably disposed at a position between the air outlet guide body 101 and the airflow guide portion 102. And an actuator 103 that is tilted to the right.
[0004]
The actuator 103 has a temperature sensor that changes the protruding amount of the needle 103b from the sensor main body 103a in response to the temperature change of the surrounding airflow. The needle 103b is provided on the outlet main body 101 side, and the sensor main body 103a is provided on the outlet main body 101 side. A spring 103c that is attached to each of the airflow guide portions 102 and urges the sensor body 103a in the direction of pushing the needle 103b is provided.
[0005]
In the conventional outlet device 100 having the above-described configuration, the airflow guide unit 102 is moved by the action of the actuator 103 according to the temperature of the conditioned air, and the angle with respect to the outlet body 101 is adjusted. In the case of cooling, the sensor main body 103a hitting the cold draws the needle 103b by the urging of the spring 103c to reduce the protruding amount, and the angle of the air flow guide portion 102 is raised with respect to the outlet main body 101, and the cold air is left as it is. Blow horizontally and disperse in the room.
[0006]
On the other hand, in the case of heating, the sensor body 103a that has been warmed pushes the needle 103b to increase the amount of protrusion, thereby inclining the angle of the air flow guide portion 102 with respect to the outlet body 101 and causing light warm air to move diagonally downward. By blowing out, the warm air reaches further downward so that the entire indoor space can be efficiently warmed.
[0007]
[Problems to be solved by the invention]
Since the conventional air outlet device is configured as described above, if the indoor space subject to air conditioning in which the nozzle type air outlet device is disposed is a large space area such as a theater, a hall, or an arena, In order to perform air conditioning evenly to people's activity areas such as near the surface and audience seats, air outlets are arranged above the wall and on the ceiling so that the mixing period of conditioned air and room air is sufficient, and A large amount of airflow needs to be blown out from the air outlets. For this reason, incidental facilities such as ducts leading to the air outlets become large due to the large space, which makes it difficult to arrange them. In particular, in the case of cooling, if an air outlet and a duct are arranged near the ceiling in order to make sure that the cold air reaches the active area by making the best use of the descending action of the cold air, the duct facility has a significantly long path. In combination with the difficulty of the installation work, not only the cost is increased, but also there is a problem that the warm air having the property of rising in the case of heating cannot be appropriately reached to the lower activity area. In addition, when the upper structure is covered with a light-transmitting material such as glass for lighting such as an arena, it is not possible to install the air outlet in this part, so the air outlet is arranged below. There was a problem that it was difficult to perform air conditioning evenly in the room because it had to adopt a structure.

[0017]
In each of the drawings, the air outlet device 10 according to the present embodiment is formed as a hollow cylindrical body in which a glass wool layer is provided as a heat insulating material inside a metal cylindrical outer shell, and an opening portion 11a having a rectangular opening cross section on a peripheral side surface. The blower outlet body 11 projecting vertically upward from the floor (not shown) of the indoor space and the opening area inside the blower outlet body 11 near the opening 11a are partially closed. An airflow guide plate 12 provided, an airflow direction adjusting plate 13 that is endlessly hinged to the airflow guide plate 12 in an opening region in the air outlet body, and one end portion of the airflow guide plate The actuator is fixed to the guide plate 12 and has the other end fixed to the wind direction adjusting plate 13, and expands and contracts according to the temperature of the conditioned air, and acts as an actuator for tilting the air direction adjusting plate 13 with respect to the air flow guide plate 12. With a temperature sensor 14 That.
[0018]
The outlet body 11 is a hollow cylinder having a length such that the height from the floor is higher than the active area, the lower end portion being fixed to the floor, and a predetermined length away from the closed upper end portion. An opening 11a for sending conditioned air toward the indoor side is formed in the peripheral side surface, and the lower end is connected to a duct (not shown) inside the floor to take in conditioned air, and this conditioned air is taken into the opening 11a. It is the structure which blows out from the interior space. In addition, a cover 11b having a high opening ratio is disposed in the opening 11a of the outlet body 11 so that foreign matter does not enter the outlet body 11 from here.
[0019]
The airflow guide plate 12 is formed in a plate-like body having an arc portion that is in close contact with the inner surface of the air outlet body 11, and the airflow direction adjusting plate 13 is pivotally supported at an end facing the opening region in the air outlet body 11. Two hinge parts 12a are arrange | positioned, and it is the structure arrange | positioned by partially closing the opening part 11a vicinity part among opening areas.
[0020]
The airflow direction adjusting plate 13 is formed in a substantially rectangular plate-like body, and its end is fixed to the hinge portion 12a of the airflow guide plate 12 and integrated with the airflow guide plate 12 and tilted inward of the air outlet body 11. It is a configuration that is freely arranged and changes the direction of the air flow by changing the angle with respect to the air flow guide plate 12.
[0021]
The temperature sensor 14 that constitutes the actuator changes the protruding amount of the needle 14b from the sensor body 14a in response to a change in ambient ambient temperature, and the two sensor bodies 14a are arranged at both ends of one needle 14b. The sensor main body 14a on one end side is fixed to one end portion of the support member 12b disposed on the lower surface of the airflow guide plate 12, and the sensor main body 14a on the other end side is fixed on the airflow direction adjusting plate 13. It is the structure arrange | positioned by pivotally attaching to the mounting member 13a which protruded from the auxiliary | assistant member 14c via the auxiliary member 14c. In addition to this, a spring 15 is disposed between the sensor body 14a on the other end side and the other end of the support member 12b, and the sensor bodies 14a are biased toward each other. .
[0022]
These temperature sensors 14 change the distance between the sensor bodies 14a by the change in the protrusion amount of the needle 14b due to the airflow temperature, and in the most extended position, the airflow direction adjusting plate 13 is arranged in a horizontal direction in a series with the airflow guide plate 12, At the most contracted position, the wind direction adjusting plate 13 is changed to a direction perpendicular to the airflow guide plate 12. However, the area where the air flow guide plate 12 and the airflow direction adjusting plate 13 are continuously arranged in a row and closes the inside of the air outlet main body 11 is less than half of the opening area cross section of the air outlet main body 11.
[0023]
Next, the air flow blowing operation in the air outlet device based on the above configuration will be described. In the case of cooling, when the cool air sent from the duct enters the outlet body 11, each sensor body 14 a of the temperature sensor 14 draws in the needle 14 b to reduce the distance between each other by hitting the cool air, and the air direction adjustment plate 13 is air-flowed. Tilt downward with respect to the guide plate 12, and the wind direction adjusting plate 13 is set substantially perpendicular to the airflow guide plate 12. Thereby, it will be in the state where the channel cross-sectional area between the wind direction adjustment board 13 and the blower outlet main body 11 inner surface expanded. The cold air passes through the passage portion between the wind direction adjusting plate 13 and the inner surface of the air outlet main body 11, and changes from the opening 11 a to the substantially horizontal direction as it is along the air flow guide plate 12 with almost no change in the air flow speed. Blow out indoors. Cooling the indoor air without causing a draft by causing the cold air heavier than the indoor air to be blown out horizontally from the opening 11a located at a higher position than the active area, so that the air is sufficiently diffused to reach the active area. The effect is great and the room can be cooled in a short time.
[0024]
On the other hand, in the case of heating, when the warm air sent from the duct enters the outlet body 11, the sensor main body 14a of the temperature sensor 14 pushes the needle 14b to increase the distance between them, and the air flow guides. The air direction adjusting plate 13 is rotated upward with respect to the plate 12 in the opposite direction to that during cooling, so that the air flow guide plate 12 and the air flow guide plate 12 are arranged in a substantially horizontal direction. Thereby, the passage cross-sectional area between the wind direction adjusting plate 13 and the air outlet main body 11 is narrowed. The warm air travels upward in the air outlet body 11 and passes through a narrow passage portion between the air direction adjusting plate 13 and the inner surface of the air outlet body 11 to increase the air velocity. Reach the top inside. By ensuring the length from the other end of the outlet body 11 to the opening 11a as appropriate, the airflow is reversed from the upper part in the outlet body 11 toward the opening 11a and the downward velocity component is generated. As a result, the air current blows into the room obliquely downward from the opening 11a. Warm air that is lighter than the indoor air is blown obliquely downward from the opening 11a at a position higher than the active area, so that the active area can be reliably reached and the temperature of the indoor air is greatly increased. Can warm up.
[0025]
In both cases of cooling and heating, the blown airflow attracts indoor air, but not only the front of the opening 11a but also the air on the left and right of the opening 11a can be attracted and mixed with the indoor air. The air conditioning effect can be demonstrated in a short time by progressing rapidly, and the air conditioning effect can be uniformly given to the active area.
[0026]
As described above, in the air outlet device according to the present embodiment, the air flow guide plate 12 and the air direction adjusting plate 13 are disposed inside the air outlet main body 11 protruding from the floor into a wide indoor space. By changing the distance between the direction and air direction adjusting plate 13 and the inner surface of the air outlet main body 11, the air flow can be blown out from the opening 11a at a predetermined height so as to be switched to the front of the opening 11a or obliquely downward. With a compact and pole-like appearance, it can be blended into a part of the interior design without a sense of incongruity, and the airflow direction can be changed according to the airflow temperature to ensure a sufficient reach distance. As a result, the overall air conditioning equipment can be reduced in size and cost. Further, an opening 11a is disposed on the peripheral side portion of the projecting air outlet body 11, and the air is blown into the air from the side and the rear of the air opening 11a. A large amount of air can be taken, and mixing with room air can be accelerated to improve air conditioning efficiency. In addition, since the inside of the cylinder is made of a heat insulating material, condensation is unlikely to occur on the outer surface of the cylinder even in the case of cooling.
[0027]
In the air outlet apparatus according to the above-described embodiment, the temperature sensor 14 has the sensor body 14 arranged in two stages to obtain a double stroke with respect to the temperature change, and the rotational displacement of the wind direction adjusting plate 13 is obtained. However, if the displacement of the wind direction adjusting plate 13 is small, a configuration using only one temperature sensor 14 may be used.
[0028]
(Second embodiment of the present invention)
The blower outlet apparatus which concerns on the 2nd Embodiment of this invention is demonstrated based on FIG. FIG. 7 is a partially omitted longitudinal sectional view of the air outlet device according to the present embodiment.
In the previous figure, the air outlet device 20 according to the present embodiment includes the air outlet main body 21, the airflow guide plate 22, the wind direction adjusting plate 23, and the temperature sensor 24, as in the first embodiment. The difference is that the airflow guide plate 22 is disposed at the opposite position farthest from the opening 21a of the outlet body 21, and the airflow direction adjusting plate 23 can be tilted with the airflow guide plate 22 integrally hinged to the end. It has the structure arrange | positioned in.
[0029]
Next, the air flow blowing operation in the air outlet device based on the above configuration will be described. In the case of cooling, the airflow direction adjusting plate 23 is rotated upward with respect to the airflow guide plate 22 so that the airflow guide plate 22 and the airflow guide plate 22 are in a continuous substantially horizontal direction.
