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する天井面又は壁面もしくは床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】
空気調和設備において、ダクトを通じて送られる調和空気を室内空間に吹出す吹出口装置のうち、調和空気を天井又は壁から室内空間下方の任意箇所に到達させられる吹出方向可変型のものとしては、従来、フレキシブルダクトを流用したノズル型の吹出口装置が用いられていた。このような従来の吹出口装置を図８に示す。この図８は従来の吹出口装置の概略構成図である。
【０００３】
前記図８において従来の吹出口装置１００は、所定長さの変形可能なフレキシブルダクトで形成され、天井（又は壁）５０に一端部を取付けられ、天井５０の内側のダクト５１と接続されて調和空気を供給される吹出口本体１０１と、天井５０の内側に配設される風量調整用のダンパー１０２とを備える構成である。
上記した構成の従来の吹出口装置１００においては、気流を吹出口本体１０１の他端側開口からそのまま真っ直ぐ室内に吹出しており、風向調整は、使用者が吹出口本体１０１他端部を直接手で掴んで動かし、吹出させたい方向へ吹出口本体１０１他端を向けることで行っていた。また、吹出す気流の風量調整を行う場合は、風量調整用のダンパー１０２を直接、又は遠隔で調整していた。
【０００４】
【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、フレキシブルダクトである吹出口本体１０１は弾性を有し、他端部を手で動かして向きを変えても元の位置寄りに若干戻ってしまい、正確に所望の向きに合わせることが難しいという課題を有していた。また、風向調整では吹出口本体１０１をなすフレキシブルダクト全体を変形させるため、吹出口本体１０１自体の強度、及び、力が加わる天井５０の強度を十分に確保する必要があり、コスト高になりやすい上、吹出口本体１０１外周側への植毛や断熱材配設などの保温加工が行えず、冷房時には表面への結露が発生しやすいという課題を有していた。
【０００５】
一方、風量調整については、天井５０内のダンパー１０２で行うが、調整や保守等でダンパー１０２に対し直接作業を行うために、作業者が天井５０内のダンパー１０２に近付くことを可能とする点検口がいずれかの場所に必要となり、この点検口設置のための加工にも手間とコストが別途かかってしまうという課題を有していた。
【０００６】
さらに、ダクト５１に複数の吹出口装置１００を接続している場合に、各吹出口装置１００毎にダンパー１０２で風量調整を行うと、室内空間に対する各吹出口装置１００毎の風量バランスが崩れて、あらかじめ設定された室内空間全体の熱負荷処理が困難になるという課題を有していた。
本発明は前記課題を解消するためになされたもので、気流吹出方向を確実に変化させて所定箇所へ向けての吹出が容易且つ効率よく行えると共に、方向調整可能な吹出気流に対する風量調整を行っても吹出口への供給風量を一様に保って他の吹出口への悪影響を防げる吹出口装置を提供することを目的とする。
【０００７】
【課題を解決するための手段】
本発明に係る吹出口装置は、両端開放状態の略筒状体で形成され、当該略筒状体の一端側を支持されて空気調和の対象空間内に突設され、前記一端側の開口部から空気調和用の気体を供給される吹出口本体と、当該吹出口本体の一端側から所定寸法離れた周側面位置で吹出口本体から前記空気調和対象空間へ所定長さ突出させ且つ内部を吹出口本体内に連通させて一体に配設される略筒状体の分岐筒と、前記分岐筒と前記吹出口本体他端側開口部との中間の吹出口本体内部所定位置に配設され、吹出口本体内の開口面積を変化させる風量調整手段と、前記分岐筒内に分岐筒内開口領域を開閉可能として配設され、前記風量調整手段の全開状態で分岐筒を閉止すると共に、前記風量調整手段が吹出口本体内の開口面積を小さくすると開いて吹出口本体から分岐筒内への気流の流入及び分岐筒から前記空気調和対象空間への気流の吹出を許容する気流分岐制御手段とを備え、前記分岐筒が、前記吹出口本体内に所定長さ突出すると共に、前記気流分岐制御手段が、前記分岐筒内を閉塞可能な一又は複数の略板状体で形成され、分岐筒に所定角度範囲傾動可能に配設され、前記風量調整手段による吹出口本体内の開口面積減少で前記略板状体の吹出口本体寄り側の圧力が所定の圧力以上になると開く逆止めダンパーであるものである。
このように本発明においては、空気調和対象空間に突出する吹出口本体の所定側面位置に分岐筒を配設すると共に、分岐筒内部に気流分岐制御手段を配設し、さらに吹出口本体内に風量調整手段を配設し、吹出口本体の他端側開口部から空気調和用気体を空気調和対象空間に吹出す一方、この吹出気流の風量を風量調整手段で調整し、風量調整手段で絞られて吹出口本体他端側から吹出さない分の空気調和用気体は開いた気流分岐制御手段を越えて分岐筒先端から吹出されることにより、吹出口本体に供給された空気調和用気体が全て空気調和対象空間に吹出されることとなり、吹出口本体他端側から吹出す気流に対する風量調整が吹出口本体への空気調和用気体の供給量に影響を与えず、吹出方向と風量を適切に調整して吹出口本体突出方向へ局所的に効率よく空気調和が行えると共に、空気調和対象空間全体の風量を常時バランスのとれたものとすることができる。
【０００８】
また、分岐筒を吹出口本体内に所定長さ突出させると共に、気流分岐制御手段として分岐筒内に逆止めダンパーを配設し、風量調整手段が全開状態の場合には分岐筒の吹出口本体突出部分内側の圧力を十分低くして逆止めダンパーを開放させないと共に、風量調整手段を絞った場合には吹出口本体内の圧力増加に伴って逆止めダンパーが開き、分岐筒からの気流吹出しを許容することにより、分岐筒内の開閉切替が吹出口本体内の圧力変化で制御され、風量調整手段の動作との連動が不要な簡略な分岐筒内開閉切替機構とすることができ、コストダウンが図れる上、風量調整手段の全開状態では確実に全ての空気調和用気体を吹出口本体他端から吹出せ、所望の箇所への空気調和効率を向上させられる。
【０００９】
また、本発明に係る吹出口装置は必要に応じて、一又は複数の略板状体又は略筒状体で形成され、前記略板状体の所定接線方向又は前記略筒状体の筒軸方向を前記吹出口本体の筒軸方向に対し所定角度範囲傾動可能且つ吹出口本体の筒軸周りに回動可能として吹出口本体の他端側開口部内に配設される気流案内手段を備えるものである。このように本発明においては、吹出口本体他端側に気流案内手段を配設し、吹出口本体に対する気流案内手段の回動位置及び傾斜角度を変化させて、吹出口本体他端から気流を所望の方向へ吹出せることにより、吹出口本体全体を動かさずに済むこととなり、天井又は壁の強度を強化する必要がなくなる上、吹出口本体外側に保温加工を施して結露防止が可能となる。
【００１０】
また、本発明に係る吹出口装置は必要に応じて、前記吹出口本体他端内周側に、前記吹出口本体より小さい略筒状体で形成される回動筒が吹出口本体の筒軸周りに回動自在として保持されると共に、前記気流案内手段として、前記回動筒より小さい略筒状体で形成され、回動筒内側に吹出口本体の筒軸方向と直交する軸周りに所定角度傾動自在に軸支される中ノズルを備えるものである。このように本発明においては、吹出口本体他端側に回動筒を配設すると共に、回動筒内側に気流案内手段として中ノズルを配設し、吹出口本体に対する中ノズルの回動位置及び傾斜角度を変化させて、吹出口本体他端から気流を所望の方向へ吹出せることにより、簡略な構成で吹出方向の調整が確実且つ容易に行え、気流吹出方向を所望の箇所へ向くように即座に調整でき、様々な状況に迅速に対応した空気調和が行える。
【００１１】
また、本発明に係る吹出口装置は必要に応じて、前記風量調整手段が、前記吹出口本体内を閉塞可能な一又は複数の略板状体で形成され、吹出口本体に所定角度範囲傾動可能に配設され、吹出口本体外部から傾動角度を調整されるダンパーであるものである。このように本発明においては、吹出口本体内に風量調整手段としてダンパーが配設され、吹出口本体外側からダンパーの傾動角度を調整して風量調整を行うことにより、風量調整が空気調和対象空間で行え、点検口を別途設ける必要がなく、吹出口設置に係る手間とコストを低減できる。
【００１２】
【発明の実施の形態】
以下、本発明の一実施の形態に係る吹出口装置について、図１ないし図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正面図、図２は本実施の形態に係る吹出口装置の側面図、図３は本実施の形態に係る吹出口装置の底面図、図４は本実施の形態に係る吹出口装置のダンパー全開状態縦断面図、図５は本実施の形態に係る吹出口装置のダンパー半開状態縦断面図、図６は本実施の形態に係る吹出口装置のダンパー全閉状態縦断面図である。
【００１３】
前記各図において本実施の形態に係る吹出口装置１は、両端開放状態の略筒状体で形成され、この略筒状体の一端側を天井（又は壁）５０に固定されて空気調和対象となる室内空間内に突設され、前記一端側から調和空気を供給される吹出口本体２と、この吹出口本体２の一端側から所定寸法離れた周側面位置で吹出口本体２から室内空間へ所定長さ突出させ且つ内部を吹出口本体２内に連通させて一体に配設される略筒状体の分岐筒３と、略筒状体で形成され、前記略筒状体の筒軸方向を吹出口本体２の筒軸方向に対し所定角度範囲傾動可能且つ吹出口本体２の筒軸周りに回動可能として吹出口本体２の他端側開口部内に配設される気流案内手段としての中ノズル４と、前記分岐筒３と中ノズル４との中間の前記吹出口本体２内部所定位置に配設され、吹出口本体２内の開口面積を変化させる風量調整手段としてのダンパー５と、前記分岐筒３内に分岐筒内開口領域を開閉可能として配設され、前記ダンパー５の全開状態で分岐筒３を閉止すると共に、ダンパー５が吹出口本体２内の開口面積を小さくすると開いて吹出口本体２から分岐筒３内への気流の流入及び分岐筒３から室内空間への気流の吹出を許容する気流分岐制御手段としての逆止めダンパー６とを備える構成である。
【００１４】
前記吹出口本体２は、所定の略円筒体の周側面所定箇所に別の円筒体を略Ｔ字状に突出状態で一体化されたＴ字管として形成され、外側に断熱材２ａが配設され、室内空間の天井５０に一端部を固定して下方に突設されてなり、一端部が天井５０内側のダクト５１に接続されて調和空気を取込み、この調和空気を他端側の開口部から室内空間へ吹出す構成である。また、Ｔ字管の分岐部分の内側に内接する径の円筒体を吹出口本体２内に一部突出させて一体に配設し、Ｔ字管の分岐部分と合わせて分岐筒３としている。この分岐筒３内には、前記逆止めダンパー６を傾動自在に支持するための蝶番部３ａが配設される。さらに、吹出口本体２の他端側内周には、吹出口本体２の内側に内接する径の円筒体で形成される回動筒２ｂが吹出口本体２の筒軸周りに回動自在として保持される構成である。
【００１５】
前記中ノズル４は、前記回動筒２ｂより小径の円筒体で形成され、回動筒２ｂ内側に吹出口本体２の筒軸方向と直交する軸周りに傾動自在に軸支される構成であり、回動筒２ｂ毎吹出口本体２に対し動かして回動位置を調整可能であることと合わせて、中ノズル４の開口の向きを吹出口本体２の他端より下方の任意方向に調整自在とされる。この中ノズル４で、吹出口本体２内を通った気流を中ノズル４の筒軸方向へ案内して室内空間に吹出させる仕組みである。
【００１６】
前記ダンパー５は、前記吹出口本体２内を閉塞可能な円形の板状体で形成され、吹出口本体２に所定角度範囲傾動可能に配設され、吹出口本体２外部に設けられる操作部５ａを介して吹出口本体２外側から傾動角度を調整される構成である。
前記逆止めダンパー６は、分岐筒３の内周面に沿う略円形状の板状体で形成され、所定箇所を前記分岐筒３の蝶番部３ａに固着されて分岐筒３の内側に所定角度範囲傾動自在に配設され、気流の分岐筒３内の通過を制御する構成である。この逆止めダンパー６は、分岐筒３先端側には開くが、吹出口本体２寄り側には開かない仕組みとなっている。逆止めダンパー６の周りの分岐筒３が吹出口本体２内に所定長さ突出していることで、ダンパー５全開時における逆止めダンパー６より上流側の分岐筒３内の圧力を逆止めダンパー６の下流側より低く抑えられると共に、吹出口本体２からの気流が分岐筒１１内に流れ込んで直接逆止めダンパー６を押開けるのを防ぐことができ、ダンパー５全開時には分岐筒３を閉塞して全風量を吹出口本体２下端のみから吹出せる。逆止めダンパー６の開閉がダンパー５の風量調整に伴う吹出口本体２内の圧力変化のみで制御されるため、他の調整部分との連動がない簡略な機構となり、コストダウンが図れる。
【００１７】
次に、前記構成に基づく吹出口装置における気流吹出方向及び風量調整動作について説明する。吹出方向調整は、吹出口本体２下端の中ノズル４の吹出口本体２に対する回動位置及び傾斜角度をそれぞれ調整して、中ノズル４の開口が気流を送りたい所望の箇所に向くようにすればよく、中ノズル４に案内された気流が中ノズル４の開口正面方向に吹出し、求める方向への気流が得られる状態となる。
【００１８】
一方、風量調整は、吹出口本体２外側からダンパー５の傾斜角度を調整して行う。ダンパー５を吹出口本体２の筒軸方向に平行とすると、吹出口本体２内部を下方へ向う気流に抵抗を与えず、吹出口本体２下端から吹出す風量が最大となる。この風量最大状態では、ダンパー５上流側の圧力は高くならないために、分岐筒３内の逆止めダンパー６は開かず、気流はスムーズに吹出口本体２を下方のみに進んで、中ノズル４に案内されて所定方向へ吹出す（図４参照）。
【００１９】
ダンパー５を吹出口本体２の筒軸方向に対し傾け、吹出口本体２内の開口領域を絞ると、吹出口本体２下端から吹出す風量が減少すると共に、ダンパー５上流側の圧力が高くなり、逆止めダンパー６がその前後の圧力差により開き、気流は吹出口本体２内を下方に進むと共に分岐筒３内へも進み、分岐筒３先端開口からも調和空気が室内空間に吹出すこととなる（図５参照）。
【００２０】
さらに、ダンパー５を吹出口本体２の筒軸方向に対し直角として吹出口本体２内部を閉塞する状態では、吹出口本体２下端からの吹出しが止る一方、供給された調和空気が全て吹出口本体２から分岐筒３へ進み、分岐筒３先端開口からのみ調和空気が室内空間へ吹出す（図６参照）。いずれの状態も、ダンパー５で下方への進行を妨げられた分の気流が分岐筒３から水平に吹出すことで、特に冷気の場合、局所的な冷房の他に、室内空間全体に効率よく冷気を行渡らせることができ、冷房効果が高くなる。
【００２１】
このように、本実施の形態に係る吹出口装置では、天井５０から室内空間に突出する吹出口本体２側面に分岐筒３を一体に配設すると共に、分岐筒３内部には逆止めダンパー６を、吹出口本体２内には中ノズル４とダンパー５をそれぞれ配設し、中ノズル４の向きで調和空気の吹出方向を調整可能に、且つこの吹出気流の風量をダンパー５で調整可能にし、ダンパー５が全開状態の場合には逆止めダンパー６上流側の分岐筒３内の圧力を十分低く保って逆止めダンパー６を開放させない一方、ダンパー５を絞った場合には吹出口本体２内の圧力増加で逆止めダンパー６を開放させ、分岐筒３からの気流吹出を許容させることから、ダンパー５で吹出口本体２他端側からの吹出を制限された分の調和空気を分岐筒３から吹出せ、吹出口本体２に供給された調和空気を全て室内空間に吹出せることとなり、吹出口本体２他端から吹出す気流に対する風量調整が吹出口本体２への調和空気供給量に影響を与えず、吹出方向と風量を適切に調整して局所的に効率よく空気調和が行えると共に、常時室内空間全体の風量を当初の設定に基づいたバランスのとれたものとすることができる。また、吹出口本体２他端の中ノズル４の向き調整のみで所望の方向へ吹出せ、吹出方向調整で吹出口本体２全体を動かさずに済むこととなり、天井５０の強度を強化する必要がなくなる上、吹出口本体２外側に断熱材２ａを配設して保温でき、冷房の場合でも吹出口本体２外面に結露を生じさせない。さらに、吹出口本体２外側からダンパー５の傾動角度を調整して風量調整を室内で行え、点検口を別途設ける必要もない。
【００２２】
なお、前記実施の形態に係る吹出口装置においては、吹出口本体２他端の気流案内手段として円筒体の中ノズル４を配設する構成としているが、これに限らず、気流案内手段として、一又は複数の略板状体で形成され、この略板状体の所定接線方向を吹出口本体２の筒軸方向に対し所定角度範囲傾動可能且つ吹出口本体２の筒軸周りに回動可能として吹出口本体２の他端側開口部内に配設される案内羽根を用いる構成とすることもできる。また、吹出口本体２及び分岐筒３をそれぞれ円筒体とする構成としているが、方形、矩形など他の開口断面形状の筒体とする構成としてもよい。
【００２３】
また、前記実施の形態に係る吹出口装置においては、吹出口本体２と分岐筒３を一体の固定状態に形成する構成としているが、これに限らず、吹出口本体２の分岐筒３連結部分を別体として残りの部分に対し分岐筒３ごと吹出口本体２筒軸周りに回動自在に配設し、分岐筒３からの気流吹出し方向を水平各方向に調整可能にする構成とすることもでき、吹出口本体２の他端側からの吹出と合わせて室内空間の様々な状況により適切に対応した空気調和が行える。
【００２４】
また、前記実施の形態に係る吹出口装置においては、天井５０に吹出口本体２の一端側を取付けて室内空間に配設する構成としているが、これに限らず、吹出口本体２の一端側を床６０に固定して上方へ突出する状態に配設する構成とすることもでき、一例として図７に示すように、吹出口本体２の他端側開口部に上下動可能な気流案内部７を配設し、この気流案内部７に間接照明器具としてランプ７ａ及び傘７ｂを取付けると共に、冷気が供給されると気流案内部７を上昇させて吹出口本体２の他端側開口部を全開状態とし、且つ暖気が供給されると気流案内部７を下げて他端側開口部を全閉状態とする温度感知機能付のアクチュエータ（図示を省略）を配設し、気流案内部７を前記風量調整手段としても用いる構成とすることもでき、床側から冷気が供給される場合は冷気が吹出口本体２内を通って他端側開口部から気流案内部７に沿って略水平に吹出し（図７（Ａ）参照）、冷気を室内空間に広範囲に拡散させられる一方、暖気が供給される場合は、暖気が床６０近くの二つの分岐筒３から吹出す（図７（Ｂ）参照）こととなり、温かい空気を室内に効率よく供給できる。
【００２５】
【発明の効果】
以上のように本発明によれば、空気調和対象空間に突出する吹出口本体の所定側面位置に分岐筒を配設すると共に、分岐筒内部に気流分岐制御手段を配設し、さらに吹出口本体内に風量調整手段を配設し、吹出口本体の他端側開口部から空気調和用気体を空気調和対象空間に吹出す一方、この吹出気流の風量を風量調整手段で調整し、風量調整手段で絞られて吹出口本体他端側から吹出さない分の空気調和用気体は開いた気流分岐制御手段を越えて分岐筒先端から吹出されることにより、吹出口本体に供給された空気調和用気体が全て空気調和対象空間に吹出されることとなり、吹出口本体他端側から吹出す気流に対する風量調整が吹出口本体への空気調和用気体の供給量に影響を与えず、吹出方向と風量を適切に調整して吹出口本体突出方向へ局所的に効率よく空気調和が行えると共に、空気調和対象空間全体の風量を常時バランスのとれたものとすることができるという効果を奏する。
【００２６】

【００２８】
また、本発明によれば、吹出口本体他端側に回動筒を配設すると共に、回動筒内側に気流案内手段として中ノズルを配設し、吹出口本体に対する中ノズルの回動位置及び傾斜角度を変化させて、吹出口本体他端から気流を所望の方向へ吹出せることにより、簡略な構成で吹出方向の調整が確実且つ容易に行え、気流吹出方向を所望の箇所へ向くように即座に調整でき、様々な状況に迅速に対応した空気調和が行えるという効果を有する。
【００２９】
また、本発明によれば、本発明に係る吹出口装置は必要に応じて、前記風量調整手段が、前記吹出口本体内を閉塞可能な一又は複数の略板状体で形成され、吹出口本体に所定角度範囲傾動可能に配設され、吹出口本体外部から傾動角度を調整されるダンパーであるものである。このように本発明においては、吹出口本体内に風量調整手段としてダンパーが配設され、吹出口本体外側からダンパーの傾動角度を調整して風量調整を行うことにより、風量調整が空気調和対象空間で行え、点検口を別途設ける必要がなく、吹出口設置に係る手間とコストを低減でき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 ceiling surface or a wall surface or a floor surface facing a space to be air-conditioned, changes a blowing direction of the air-conditioning gas to the air-conditioning target space, and The present invention relates to a blowout device that can appropriately reach a predetermined location in an air conditioning target space.
[0002]
[Prior art]
Among air outlets that blow out conditioned air sent through a duct into an indoor space in an air conditioning facility, as a blowing direction variable type that allows conditioned air to reach an arbitrary location below the indoor space from the ceiling or wall, A nozzle-type air outlet device using a flexible duct has been used. Such a conventional air outlet apparatus is shown in FIG. FIG. 8 is a schematic configuration diagram of a conventional air outlet device.
[0003]
In FIG. 8, the conventional air outlet device 100 is formed of a deformable flexible duct having a predetermined length, and has one end attached to the ceiling (or wall) 50 and is connected to the duct 51 inside the ceiling 50 for harmony. The structure includes an air outlet main body 101 to which air is supplied and an air volume adjusting damper 102 disposed inside the ceiling 50.
In the conventional outlet device 100 having the above-described configuration, the airflow is blown straight out from the opening on the other end side of the outlet body 101 into the room, and the user can directly adjust the other end of the outlet body 101 by hand. The other end of the air outlet body 101 is directed in the direction in which it is desired to be blown. Further, when adjusting the air volume of the airflow to be blown out, the damper 102 for adjusting the air volume is adjusted directly or remotely.
[0004]
[Problems to be solved by the invention]
Since the conventional air outlet device is configured as described above, the air outlet body 101, which is a flexible duct, has elasticity, and even if the other end is moved by hand to change the direction, the air outlet body 101 is slightly closer to the original position. It has returned and had the subject that it was difficult to adjust to a desired direction correctly. In addition, since the entire flexible duct forming the outlet body 101 is deformed in the wind direction adjustment, it is necessary to sufficiently ensure the strength of the outlet body 101 itself and the strength of the ceiling 50 to which the force is applied, which tends to increase the cost. In addition, heat insulation processing such as flocking on the outer peripheral side of the air outlet main body 101 and arrangement of a heat insulating material cannot be performed, and there is a problem that condensation on the surface is likely to occur during cooling.
[0005]
On the other hand, the air volume adjustment is performed by the damper 102 in the ceiling 50, but in order to perform the work directly on the damper 102 for adjustment, maintenance, etc., an inspection that enables the worker to approach the damper 102 in the ceiling 50 is possible. There is a problem that a mouth is required at any place, and the processing for installing the inspection port requires labor and cost.
[0006]
Furthermore, when a plurality of air outlet devices 100 are connected to the duct 51 and the air volume is adjusted by the damper 102 for each air outlet device 100, the air volume balance of each air outlet device 100 with respect to the indoor space is lost. However, there is a problem that it becomes difficult to perform heat load processing on the entire indoor space set in advance.
The present invention has been made in order to solve the above-mentioned problems, and it is possible to easily and efficiently perform blowing toward a predetermined location by reliably changing the air flow blowing direction, and to adjust the air volume with respect to the blowing air flow that can be adjusted in direction. However, it aims at providing the blower outlet apparatus which can maintain the supply air quantity to a blower outlet uniformly, and can prevent the bad influence to other blower outlets.
[0007]
[Means for Solving the Problems]
The blowout device according to the present invention is formed of a substantially cylindrical body with both ends open, and is supported by one end side of the substantially cylindrical body so as to project into an air-conditioning target space.

[0013]
In each of the drawings, the air outlet device 1 according to the present embodiment is formed of a substantially cylindrical body that is open at both ends, and one end side of the substantially cylindrical body is fixed to a ceiling (or wall) 50 to be subject to air conditioning. The air outlet main body 2 that protrudes into the indoor space and is supplied with conditioned air from the one end side, and the air outlet body 2 from the air outlet main body 2 at a circumferential side surface that is a predetermined distance away from one end side of the air outlet main body 2. A substantially cylindrical branch tube 3 that is protruded by a predetermined length and is integrally disposed with the inside thereof communicating with the air outlet body 2, and a cylindrical shaft formed by the substantially cylindrical body. As an air flow guide means disposed in the opening on the other end side of the outlet body 2 such that the direction can be tilted within a predetermined angle range with respect to the cylinder axis direction of the outlet body 2 and can be rotated around the cylinder axis of the outlet body 2. A predetermined position inside the outlet body 2 between the middle nozzle 4 and the branch cylinder 3 and the middle nozzle 4 A damper 5 as an air volume adjusting means for changing the opening area in the outlet body 2 and a branch cylinder opening area in the branch cylinder 3 so as to be openable and closable. When the branch cylinder 3 is closed and the damper 5 reduces the opening area in the outlet body 2, it opens and the airflow flows from the outlet body 2 into the branch cylinder 3 and the airflow from the branch cylinder 3 into the indoor space. And a non-return damper 6 as airflow branching control means for allowing the airflow.
[0014]
The blower outlet body 2 is formed as a T-tube integrated with another cylindrical body projecting in a substantially T-shape at a predetermined position on the peripheral side surface of a predetermined substantially cylindrical body, and a heat insulating material 2a is disposed on the outside. One end is fixed to the ceiling 50 of the indoor space and protrudes downward. One end is connected to a duct 51 inside the ceiling 50 to take in conditioned air, and this conditioned air is opened to the other end. It is the structure which blows out from the interior space. In addition, a cylindrical body having a diameter inscribed inside the branch portion of the T-shaped tube is partly protruded into the outlet body 2 so as to be integrated with the branch portion of the T-shaped tube. In the branch cylinder 3, a hinge part 3a for supporting the non-return damper 6 in a tiltable manner is disposed. Further, on the inner periphery of the other end side of the air outlet body 2, a rotating cylinder 2 b formed of a cylindrical body having a diameter inscribed inside the air outlet body 2 is configured to be rotatable around the tube axis of the air outlet body 2. It is a configuration to be held.
[0015]
The middle nozzle 4 is formed of a cylindrical body having a diameter smaller than that of the rotating cylinder 2b, and is supported on the inner side of the rotating cylinder 2b so as to be tiltable about an axis orthogonal to the cylinder axis direction of the outlet body 2. In addition to the fact that the rotation position can be adjusted by moving the rotating cylinder 2b with respect to the outlet body 2, the opening direction of the middle nozzle 4 can be adjusted in an arbitrary direction below the other end of the outlet body 2. It is said. This middle nozzle 4 is a mechanism that guides the airflow passing through the outlet body 2 in the direction of the cylinder axis of the middle nozzle 4 and blows it out into the indoor space.
[0016]
The damper 5 is formed of a circular plate-like body capable of closing the inside of the air outlet body 2, is disposed on the air outlet body 2 so as to be tiltable within a predetermined angle range, and is provided on the outside of the air outlet body 2. It is the structure by which a tilt angle is adjusted from the blower outlet main body 2 outer side.
The non-return damper 6 is formed of a substantially circular plate-like body along the inner peripheral surface of the branch cylinder 3, and a predetermined portion is fixed to the hinge portion 3 a of the branch cylinder 3 to be inside the branch cylinder 3 at a predetermined angle. It is the structure which is arrange | positioned freely in the range tilt and controls the passage of the airflow in the branch cylinder 3. This non-return damper 6 opens on the tip side of the branch cylinder 3 but does not open on the side close to the outlet body 2. The branch cylinder 3 around the check damper 6 protrudes into the outlet body 2 by a predetermined length, so that the pressure in the branch cylinder 3 upstream of the check damper 6 when the damper 5 is fully opened is reduced to the check damper 6. It is possible to prevent the airflow from the outlet body 2 from flowing into the branch cylinder 11 and directly pushing the non-return damper 6 open. When the damper 5 is fully opened, the branch cylinder 3 is closed. The entire air volume can be blown out only from the lower end of the outlet body 2. Since the opening / closing of the non-return damper 6 is controlled only by the pressure change in the air outlet body 2 associated with the adjustment of the air volume of the damper 5, a simple mechanism that is not linked to other adjustment portions can be achieved, and the cost can be reduced.
[0017]
Next, the air flow blowing direction and the air volume adjusting operation in the air outlet device based on the above configuration will be described. The blow direction adjustment is performed by adjusting the rotation position and the inclination angle of the middle nozzle 4 at the lower end of the blow body 2 with respect to the blow body 2 so that the opening of the middle nozzle 4 is directed to a desired location where the air flow is to be sent. The air flow guided to the middle nozzle 4 is blown out in the front direction of the opening of the middle nozzle 4, and the air flow in the desired direction is obtained.
[0018]
On the other hand, the air volume adjustment is performed by adjusting the inclination angle of the damper 5 from the outside of the outlet body 2. When the damper 5 is parallel to the tube axis direction of the air outlet body 2, the airflow that blows out from the lower end of the air outlet body 2 is maximized without giving resistance to the airflow that goes downward in the air outlet body 2. In this maximum air volume state, the pressure upstream of the damper 5 does not increase, so the non-return damper 6 in the branch cylinder 3 does not open, and the airflow smoothly advances only downward through the outlet body 2 to the middle nozzle 4. Guided and blown out in a predetermined direction (see FIG. 4).
[0019]
When the damper 5 is tilted with respect to the tube axis direction of the outlet body 2 and the opening area in the outlet body 2 is narrowed, the amount of air blown from the lower end of the outlet body 2 is reduced and the pressure on the upstream side of the damper 5 is increased. The non-return damper 6 opens due to the pressure difference between the front and the back, and the airflow proceeds downward in the outlet body 2 and also into the branch cylinder 3, and conditioned air is blown into the indoor space from the opening of the branch cylinder 3. (See FIG. 5).
[0020]
Further, in a state in which the damper 5 is at right angles to the cylinder axis direction of the air outlet body 2 and the inside of the air outlet body 2 is closed, the blowout from the lower end of the air outlet body 2 stops, while all the supplied conditioned air is discharged. The conditioned air advances from 2 to the branch cylinder 3 and blows conditioned air into the indoor space only from the opening at the tip of the branch cylinder 3 (see FIG. 6). In any state, the air flow that has been prevented from traveling downward by the damper 5 is blown horizontally from the branch tube 3, and particularly in the case of cold air, in addition to local cooling, it can be efficiently applied to the entire indoor space. Cold air can be distributed and the cooling effect is enhanced.
[0021]
As described above, in the air outlet device according to the present embodiment, the branch cylinder 3 is integrally disposed on the side surface of the air outlet main body 2 protruding from the ceiling 50 into the indoor space, and the check damper 6 is provided inside the branch cylinder 3. The middle nozzle 4 and the damper 5 are respectively disposed in the outlet body 2 so that the direction of the conditioned air can be adjusted by the direction of the middle nozzle 4 and the amount of the blown airflow can be adjusted by the damper 5. When the damper 5 is fully opened, the pressure in the branch cylinder 3 upstream of the check damper 6 is kept sufficiently low so that the check damper 6 is not opened. Since the non-return damper 6 is opened by increasing the pressure of the air flow and the airflow from the branch tube 3 is allowed to be allowed, the conditioned air corresponding to the amount of air blown from the other end side of the outlet body 2 by the damper 5 is restricted. Blow out from the outlet 2 All the supplied conditioned air can be blown into the indoor space, and the air volume adjustment with respect to the air flow blown from the other end of the blower outlet body 2 does not affect the amount of conditioned air supplied to the blower outlet body 2, and the blowing direction and the air volume can be changed. Appropriate adjustment can be performed to efficiently and locally harmonize the air, and the air volume of the entire indoor space can always be balanced based on the initial setting. Further, it is possible to blow out in a desired direction only by adjusting the direction of the middle nozzle 4 at the other end of the outlet body 2, and it is not necessary to move the entire outlet body 2 by adjusting the outlet direction, and it is necessary to strengthen the strength of the ceiling 50. In addition, the heat insulating material 2a can be disposed outside the air outlet body 2 to keep the temperature, and even in the case of cooling, no condensation occurs on the outer surface of the air outlet body 2. Furthermore, the air volume can be adjusted indoors by adjusting the tilt angle of the damper 5 from the outside of the air outlet body 2, and there is no need to provide a separate inspection port.

It is possible to perform air conditioning appropriately corresponding to various situations in the indoor space in combination with the blowout from the other end side of the blowout outlet body 2.
[0024]

When cold air is supplied, the airflow guide 7 is raised to open the other end side opening of the outlet body 2. An actuator (not shown) with a temperature sensing function is provided to lower the airflow guide 7 when the warm air is supplied and the other end side opening is fully closed. It can also be configured to be used as the air volume adjusting means, and the floor When the cool air is supplied from the air outlet, the cool air is blown out substantially horizontally along the air flow guide portion 7 from the opening on the other end side through the air outlet body 2 (see FIG. 7A), and the cool air is widely distributed in the indoor space. On the other hand, when warm air is supplied, warm air blows out from the two branch cylinders 3 near the floor 60 (see FIG. 7B), and warm air can be efficiently supplied into the room.
