Description

【０００１】
【発明の属する技術分野】
本発明は、供給される調和空気を空気調和対象となる室内空間に吹出す吹出口装置に関し、特に簡略な構造で結露を防止することができ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の天井又は壁面に配設され、調和空気を吹出す吹出口装置においては、冷房の際に、吹出す冷気により吹出口装置の室内空間に面する部分が冷却され、誘引された室内の暖気がこうした部分に接触して結露を生じる場合があった。このため、従来から、この結露を防止するための各種の吹出口装置が使用されており、こうした従来の吹出口装置の例として図５に示すものがある。この図５は従来の吹出口装置の概略構成断面図である。
【０００３】
前記図５において従来の吹出口装置１００は、天井５０に取付けられ、空気調和機（図示を省略）から供給される調和空気を取込み、この調和空気を空気調和の対象となる室内空間側へ流通させる開口領域１１１を有する開口枠体１１０と、断熱性材で形成され、前記開口枠体１１０に係合して開口枠体１１０の室内空間側を覆う複数の断熱カバー１２０と、前記開口枠体１１０に回動自在に配設され、調和空気の吹出す向きを調整する複数の風向調整体１３０とを備える構成である。
【０００４】
前記構成に基づく従来の吹出口装置においては、開口枠体１１０に配設された各風向調整体１３０を適宜回動させ、空気調和機（図示を省略）から供給される低温の調和空気を開口領域１１１から一次空気Ａとして室内に吹出す。この一次空気Ａの冷気により開口枠体１１０の各部は冷却される。一方、この開口枠体１１０の室内空間側に面する部分は断熱カバー１２０で覆われていることから、一次空気Ａにより室内の暖気が二次空気Ｂとして誘引されても、冷えた開口枠体１１０の室内空間側表面に二次空気Ｂが接触せず、結露が発生しない。
【０００５】
【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、調和空気の吹出しに伴って開口枠体１１０の室内空間側表面近傍には確実に二次空気が誘引され、そのままでは結露が生じるために表面全てに断熱カバー１２０を配設する必要があり、吹出口装置の構造が複雑化し、コスト高になるばかりでなく、組立取付作業も複雑化して作業に手間がかかってしまうという課題を有した。
本発明は前記課題を解消するためになされたもので、簡略な構造で結露を防止することができる吹出口装置を提供することを目的とする。
【０００６】
【課題を解決するための手段】
本発明に係る吹出口装置は、所定形状の開口領域を内側に有する略枠状体で形成され、当該略枠状体の前記開口領域を通り抜ける方向におけるいずれか一方の端部に開口領域側及び開口領域に対する外側へそれぞれ所定幅突出する額縁部が形成され、空気調和対象となる空間に面する天井もしくは壁の所定位置に前記額縁部を前記空気調和対象空間側に向けて配設され、前記開口領域を通じて空気調和用の気体を空気調和対象空間側へ流通させる開口枠体と、前記開口枠体の少なくとも開口領域に面する内周側に沿って所定の厚さで配設される断熱材と、前記開口枠体の開口領域横断面に略等しい形状の略板状体で形成され、当該略板状体に所定形状の取付孔が所定の配置で複数穿設され、前記開口枠体の開口領域側に突出する額縁部より上流側に所定寸法離れた開口枠体内側位置に前記断熱材を介して配設される案内部支持体と、前記空気調和用気体を通す所定形状の吹出孔が形成され、前記案内部支持体の各取付孔に配設される複数の気流案内部とを備え、前記案内部支持体縁部分と前記開口枠体の額縁部との間に生じる隙間部分が案内部支持体より上流側の開口領域に連通し、前記隙間部分から空気調和用気体を案内部支持体表面に沿わせて案内部支持体中央側へ吹出すと共に、前記各気流案内部の吹出孔から空気調和用気体を空気調和対象空間へ所定の向きに吹出すものである。
【０００７】
このように本発明においては、開口枠体内側に案内部支持体が配設され、空気調和用気体を吹出す複数の気流案内部が案内部支持体に取付けられると共に、案内部支持体と開口枠体の額縁部との間に上流側の開口領域に連通する隙間部分が形成され、この隙間部分から気流を案内部支持体表面に沿わせて吹出せることにより、冷房時における気流案内部からの空気調和用気体の吹出しで空気調和対象空間内のより暖かい気体が案内部支持体表面付近まで誘引されても、隙間部分から案内部支持体表面に沿って吹出される空気調和用気体がエアカーテンとして働いて暖かい気体と冷えた案内部支持体表面との接触を妨げることとなり、暖かい気体の接触による案内部支持体表面への結露を防止でき、結露による汚損や水滴落下をなくして吹出口やその周辺の美観を保てる。
【０００８】
また、本発明に係る吹出口装置は必要に応じて、前記案内部支持体が、縁部分で且つ前記額縁部と重なって空気調和対象空間側に面しない所定位置に、案内部支持体外周と略平行なスリット状の開口孔を複数形成されてなり、当該開口孔を通じて、案内部支持体より上流側の開口領域から空気調和用気体が前記案内部支持体縁部分と開口枠体額縁部との間の隙間部分に達するものである。このように本発明においては、案内部支持体縁部分にスリット状の開口孔が配設され、この開口孔で案内部支持体と額縁部との間の隙間部分が上流側の開口領域に連通し、開口孔を通った空気調和用気体が隙間部分から案内部支持体表面に沿って吹出すことにより、冷房時における空気調和用気体の吹出しに伴って誘引される空気調和対象空間内のより暖かい気体と冷えた案内部支持体表面との接触が防げ、案内部支持体表面への結露を防止でき、結露による汚損や水滴落下をなくして吹出口やその周辺の美観を維持できる。
【０００９】
また、本発明に係る吹出口装置は必要に応じて、前記案内部支持体が、外周部分と前記断熱材との間に一又は複数の所定の通風領域を介在させて前記開口枠体内側に配設され、前記通風領域を通じて、案内部支持体より上流側の開口領域から空気調和用気体が前記案内部支持体縁部分と開口枠体額縁部との間の隙間部分に達するものである。このように本発明においては、案内部支持体と開口枠体内周の断熱材との間に通風領域が設定され、この通風領域で案内部支持体と額縁部との間の隙間部分が上流側の開口領域に連通し、通風領域を通った空気調和用気体が隙間部分から案内部支持体表面に沿って吹出すことにより、冷房時における空気調和用気体の吹出しに伴って誘引される空気調和対象空間内のより暖かい気体と冷えた案内部支持体表面との接触が防げ、案内部支持体表面への結露を防止でき、結露による汚損や水滴落下をなくして吹出口やその周辺の美観を維持できる。
【００１０】
また、本発明に係る吹出口装置は必要に応じて、前記案内部支持体の取付孔が円形に形成され、当該取付孔に前記気流案内部が回動自在に配設されるものである。このように本発明においては、気流案内部が案内部支持体の円形の取付孔に回動自在に取付けられ、気流案内部の向きを回動調整して空気調和用気体の吹出方向を自由に変化させられることにより、空気調和対象空間の状態や空気調和の用途に応じた最適な吹出パターンが容易に得られ、空気調和効果を大幅に向上させられる。
【００１１】
また、本発明に係る吹出口装置は必要に応じて、前記開口枠体の開口領域及び前記案内部支持体が細長い矩形状に形成されてなると共に、前記案内部支持体の各取付孔が案内部支持体長手方向に複数列で千鳥状配置として穿設されるものである。このように本発明においては、案内部支持体の取付孔を複数列の千鳥状配置とし、気流案内部がそれぞれ互い違いに配置されて空気調和用気体を吹出すことにより、気流案内部から吹出される気流が別の気流案内部からの気流と互いに干渉しにくく、空気調和効果を最大限発揮させられると共に、案内部支持体と額縁部の隙間部分からの気流がいずれかの気流案内部と干渉してこの気流案内部から先の案内部支持体表面に沿って進めなくなっても、隙間部分のいずれか他の位置から吹出した気流が互い違いに並んだ気流案内部の間を通って案内部支持体表面に沿って進むこととなり、いずれの案内部支持体表面にももれなく隙間部分からの気流を到達させられ、案内部支持体表面への空気調和対象空間内のより暖かい気体の接触を確実に防いで結露を防止できる。また、千鳥状配置とすることで吹出口装置の幅を狭くしつつ気流案内部の数を最大限設定することができ、所定の空気調和効果を維持できる。
【００１２】
また、本発明に係る吹出口装置は必要に応じて、断熱性材料で形成され、前記開口枠体の額縁部の内周側に一側端部が係合すると共に、額縁部の外周側に他側端部が係合して、額縁部の空気調和対象空間側表面を覆って配設される断熱カバーを備えるものである。このように本発明においては、断熱カバーが開口枠体の額縁部に取付けられ、額縁部表面を覆うことにより、気流案内部からの空気調和用気体吹出しに伴って誘引される空気調和対象空間内のより暖かい気体と額縁部との直接の接触が防げ、額縁部が冷却されて温度が低下した場合でも、額縁部表面に暖かい誘引気体を接触させず結露を発生させない。
【００１３】
【発明の実施の形態】
（本発明の第１の実施形態）
以下、本発明の第１の実施形態に係る吹出口装置について、図１〜図３に基づいて説明する。本実施の形態においては、低温の調和空気を吹出すライン型の吹出口装置に適用した例を示す。図１は本実施形態に係る吹出口装置の側面図及び底面図、図２は図１におけるＡ−Ａ断面図、図３は図１におけるＢ−Ｂ一部省略断面図を示す。
【００１４】
前記各図において本実施の形態に係る吹出口装置１は、天井５０内に配設され、ダクト５１から供給される調和空気を空気調和対象空間である室内空間側へ流通させる開口領域２ａを有してなる開口枠体２と、この開口枠体２の内外周表面を覆って配設される断熱材３と、この開口枠体２の開口領域内側に配設され、開口領域を覆う略板状体の案内部支持体４と、前記案内部支持体４に回動自在に取付けられ、前記室内空間に気流を吹出す複数の気流案内部５とを備える構成である。
【００１５】
前記開口枠体２は、ライン型吹出口として細長い矩形状の開口領域２ａを内側に有する枠状体として形成されてなり、室内空間側の下端部に所定幅の額縁部２ｂを形成され、前記開口領域２ａを天井５０内でダクト５１と連通させて調和空気を取込み、この調和空気を室内空間側へ流通させる構成である。開口枠体２の開口領域２ａに面する内周側及びこれに対応する外周側位置には、それぞれ所定厚さの断熱材３が表面に沿って配設される。なお、本実施形態における開口枠体２は二つの枠状部材を組合わせて形成され、額縁部２ｂの開口領域側部分と開口領域外側部分とがそれぞれ別部材となっているが、これに限らず、開口枠体として一体成形される構成であってもよい。
【００１６】
前記案内部支持体４は、前記開口枠体２の開口領域２ａ横断面に略等しい細長い矩形状の略板状体で形成され、この略板状体に円形の取付孔４ａが略板状体長手方向に二列の千鳥状配置として複数穿設され、且つ略板状体の各縁部分の所定位置に略板状体の各外周と平行なスリット状の開口孔４ｂが複数形成され、開口枠体２の額縁部２ｂより上流側に所定寸法離れた開口枠体２内側の所定箇所に前記断熱材３を介して取付けられ、縁部分と額縁部２ｂの開口領域側部分との間に隙間部分６が生じる構成である。前記取付孔４ａを千鳥状配置とすることで、吹出口装置の幅を狭くしても気流案内部５を多く配設できるようにしており、十分な空気調和効果が得られる仕組みである。一方、前記開口孔４ｂは、開口枠体２への取付状態で前記額縁部２ｂの開口領域側部分と重なって室内空間側に面しない縁部分に形成されており、この開口孔４ｂを通じて、案内部支持体４より上流側の開口領域２ａから調和空気が前記隙間部分６に達し、気流が額縁部２ｂの存在により向きを変えて隙間部分６から略水平に吹出し、案内部支持体４表面に沿ってその中央側に向う仕組みとなっている。
【００１７】
前記気流案内部５は、調和空気を通す所定形状の吹出孔５ａが形成され、前記案内部支持体４の各取付孔４ａに嵌合されて配設される構成である。調和空気は吹出孔５ａから室内空間側へ吹出され、気流案内部５を取付孔４ａに対し回動調整して吹出方向の調整を行える。これら気流案内部５は、二列の千鳥状配置としてそれぞれ互い違いに配置されて調和空気を吹出すことから、一つの気流案内部５から吹出される気流が別の気流案内部５からの気流と互いに干渉しにくく、空気調和効果を最大限発揮させられる。本実施の形態においては、気流案内部５の吹出方向を全て同じ向きとしている。
【００１８】
次に、前記構成に基づく吹出口装置における調和空気吹出動作について説明する。
ダクト５１から送られた冷房用の調和空気が開口枠体２に入ると、案内部支持体４の上側に達して各気流案内部５に案内され、全て同じ向きとされた気流案内部５の吹出孔５ａから調和空気が略水平に吹出される（図２参照）。こうして調和空気を一次空気Ａとして各気流案内部５から室内空間に吹出すと、この一次空気Ａにより室内の暖かい空気が二次空気Ｂとして誘引され、開口枠体２の額縁部２ｂ及び案内部支持体４の室内空間側表面近傍にも室内空気が存在する状態となる。
【００１９】
この時、案内部支持体４の開口孔４ｂからも調和空気が出て、案内部支持体４縁部分と開口枠体２の額縁部２ｂとの間の隙間部分６から略水平方向に案内部支持体４表面に沿って吹出し（図２参照）、互い違いに並んだ気流案内部５の間を通って案内部支持体４表面に沿って進む（図１参照）。案内部支持体４表面のうち、気流案内部５の下流側部分には、気流案内部５から吹出した調和空気の気流が存在し、それ以外の案内部支持体４表面においては、隙間部分６から吹出した気流がもれなく到達することから、二次空気Ｂの案内部支持体４表面への接触が妨げられ、この部分への結露を確実に防止できる。また、額縁部２ｂにおいては、断熱材３の存在により開口枠体２が冷却されず、額縁部２ｂは室内空間とほぼ等しい温度を維持するため、額縁部２ｂ表面に誘引された二次空気Ｂが接触しても結露は生じない。
【００２０】
このように、本実施の形態に係る吹出口装置では、案内部支持体４縁部分にスリット状の開口孔４ｂが配設され、この開口孔４ｂで案内部支持体４と額縁部２ｂの開口領域側部分との間の隙間部分６が上流側の開口領域に連通し、開口孔４ｂを通った調和空気が隙間部分６から案内部支持体４表面に沿って吹出すことから、気流案内部５からの調和空気の吹出しに伴って誘引される暖かい二次空気と冷えた案内部支持体４表面との接触が防げ、案内部支持体４表面への結露を確実に防止でき、開口枠体２の額縁部２ｂが断熱材３により冷却されず室内温度に近い状態を維持して表面に結露を生じないことと合せ、吹出口及びその周囲の美観を保つことができる。
【００２１】
（本発明の第２の実施形態）
本発明の第２の実施形態に係る吹出口装置を図４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断面図を示す。
【００２２】
前記図４において本実施形態に係る吹出口装置１は、前記第１の実施の形態と同様に開口枠体２と、断熱材３と、案内部支持体４と、気流案内部５とを共通して備える一方、異なる点として、断熱性材料で形成され、前記開口枠体２における額縁部２ｂの内周側に内周突起片７ａが密接すると共に、前記額縁部２ｂの外周側に外周突起片７ｂが密接結合し、前記額縁部２ｂの室内側表面との間に隙間８を密閉状態で形成して配設される断熱カバー７とを備える構成を有するものである。
【００２３】
前記断熱カバー７は、額縁部２ｂの室内空間側を覆う矩形平板状に形成されてなる構成である。この断熱カバー７の取付けは、この断熱カバー７自体の弾性力と外周係合片７ａの額縁部２ｂの外周縁への係合とにより、額縁部２ｂに圧入押圧してワンタッチで取り付けられる。この時、断熱カバー７の支持突起部７ｃの先端を額縁部２ｂの表面に当接させるようにしているので、ゆがみがなく確実な取付状態を維持できると共に、隙間８を一定に保つことができる。
【００２４】
次に、前記構成に基づく吹出口装置における調和空気吹出動作について説明する。
前記第１の実施形態同様、ダクト５１から送られた冷房用の調和空気が開口枠体２に入ると、案内部支持体４の上側に達して各気流案内部５に案内され、吹出孔５ａから一次空気Ａとして吹出す。この一次空気Ａにより室内の暖かい空気が二次空気Ｂとして誘引され、額縁部２ｂ及び案内部支持体４の室内空間側表面近傍にも室内空気が存在する状態となるが、気流案内部５からの気流と共に案内部支持体４の開口孔４ｂからも調和空気が出て、隙間部分６から略水平方向に案内部支持体４表面に沿って吹出し（図４参照）、互い違いに並んだ気流案内部５の間を通って進み、案内部支持体４表面にもれなく到達することから、二次空気Ｂの案内部支持体４表面への接触が妨げられ、この部分への結露を確実に防止できる。
【００２５】
一方、額縁部２ｂにおいては、気流案内部５の向きによっては調和空気で冷却され、室内空間より温度が低下してしまう場合もあり、額縁部２ｂ表面に誘引された二次空気Ｂが直接接触すると結露を生じてしまうが、額縁部２ｂの室内側表面に断熱カバー７が配設されて二次空気Ｂの接触はなく、また、額縁部２ｂと断熱カバー７との間に密閉状態の空気層の隙間８が形成されているため、冷却された額縁部２ｂと断熱カバー７との間の熱伝導がほとんど生じず、断熱カバー７が額縁部２ｂに対し断熱状態を保たれることとなる。このため、前記断熱カバー７の表面部は冷却されることなく室内温度に近い状態を維持することができ、二次空気Ｂの接触する断熱カバー７表面においても結露を確実に防止できる。
【００２６】
このように、本実施の形態に係る吹出口装置では、前記第１の実施形態同様、案内部支持体４表面への結露を確実に防止できると共に、冷却されにくく室内温度に近い状態を維持する断熱カバー７で額縁部２ｂの室内空間側表面を覆うことから、開口枠体２の額縁部２ｂの温度が低下しても額縁部２ｂ表面に結露を発生させない。また、断熱カバー７と額縁部２ｂとの間に閉塞された隙間８が形成されることから、隙間８に介在する空気層で断熱カバー７の温度低下が極力抑制されることとなり、断熱カバー７表面への結露も確実に防止できる。
【００２７】
なお、前記第２の実施の形態に係る吹出口装置において、断熱カバー７は、取付状態において額縁部２ｂ表面との間に隙間８を形成する構成としているが、断熱カバー７自体の内部に密閉された空間の中空部を形成する構成とすることもでき、額縁部２ｂが過度に冷却されても、中空部内の気体層を隔てて断熱カバー７表面部が確実に断熱されて室温とほぼ同じ状態を保ち、断熱カバー７の室内空間側表面の温度低下が確実に防げることとなり、断熱カバー７表面への結露発生をより確実に防止できる。
【００２８】
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、案内部支持体４と開口枠体２の額縁部２ｂとの間の隙間部分６を案内部支持体４より上流側の開口領域２ａに連通させるためにスリット状の開口孔４ｂを案内部支持体４縁部分に形成する構成としているが、この他に、案内部支持体４の外周部分と開口枠体２内周の断熱材との間に調和空気を通す所定の通風領域を設ける構成とすることもでき、この通風領域を通った調和空気が隙間部分６から案内部支持体４表面に沿って吹出すことにより、前記各実施形態同様、調和空気の吹出しに伴って誘引される二次空気と冷えた案内部支持体４との接触が防げ、案内部支持体４表面への結露を確実に防止できる。
【００２９】
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、ライン型の吹出口として開口枠体２の開口領域２ａ及び案内部支持体４を細長い矩形状に形成する構成であるが、これらに限らず、正方形状や丸形状に形成する構成とすることもでき、空気調和用途、室内空間におけるデザインに合わせて適切な形状を選択できる。加えて、気流案内部５も、案内部支持体４長手方向への二列の千鳥状配置に限らず、縦横整列状態で配置したり、案内部支持体４中央部に密集させて配置したりすることもできる。
【００３０】
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２を開口領域２ａが内側に一つだけ存在する枠状体として形成し、案内部支持体４と開口枠体２の額縁部２ｂとの間の隙間部分６を通じて調和空気を案内部支持体４表面に沿って吹出す構成としているが、この他、開口枠体を天井の開口部に固定される外側枠体と、案内部支持体を支持する内側枠体からなる二重構造とし、外側枠体と内側枠体の間に調和空気を通す別の開口領域を設け、この別の開口領域を通じて調和空気を案内部支持体中央側へ略水平方向に吹出す構成とすることもでき、前記各実施形態同様、確実に吹出口装置の室内側に面する部分への結露を防ぐことができる。
【００３１】
【発明の効果】
以上のように本発明によれば、開口枠体内側に案内部支持体が配設され、空気調和用気体を吹出す複数の気流案内部が案内部支持体に取付けられると共に、案内部支持体と開口枠体の額縁部との間に上流側の開口領域に連通する隙間部分が形成され、この隙間部分から気流を案内部支持体表面に沿わせて吹出せることにより、冷房時における気流案内部からの空気調和用気体の吹出しで空気調和対象空間内のより暖かい気体が案内部支持体表面付近まで誘引されても、隙間部分から案内部支持体表面に沿って吹出される空気調和用気体がエアカーテンとして働いて暖かい気体と冷えた案内部支持体表面との接触を妨げることとなり、暖かい気体の接触による案内部支持体表面への結露を防止でき、結露による汚損や水滴落下をなくして吹出口やその周辺の美観を保てるという効果を奏する。
【００３２】
また、本発明によれば、案内部支持体縁部分にスリット状の開口孔が配設され、この開口孔で案内部支持体と額縁部との間の隙間部分が上流側の開口領域に連通し、開口孔を通った空気調和用気体が隙間部分から案内部支持体表面に沿って吹出すことにより、冷房時における空気調和用気体の吹出しに伴って誘引される空気調和対象空間内のより暖かい気体と冷えた案内部支持体表面との接触が防げ、案内部支持体表面への結露を防止でき、結露による汚損や水滴落下をなくして吹出口やその周辺の美観を維持できるという効果を有する。
【００３３】
また、本発明によれば、案内部支持体と開口枠体内周の断熱材との間に通風領域が設定され、この通風領域で案内部支持体と額縁部との間の隙間部分が上流側の開口領域に連通し、通風領域を通った空気調和用気体が隙間部分から案内部支持体表面に沿って吹出すことにより、冷房時における空気調和用気体の吹出しに伴って誘引される空気調和対象空間内のより暖かい気体と冷えた案内部支持体表面との接触が防げ、案内部支持体表面への結露を防止でき、結露による汚損や水滴落下をなくして吹出口やその周辺の美観を維持できるという効果を有する。
【００３４】
また、本発明によれば、気流案内部が案内部支持体の円形の取付孔に回動自在に取付けられ、気流案内部の向きを回動調整して空気調和用気体の吹出方向を自由に変化させられることにより、空気調和対象空間の状態や空気調和の用途に応じた最適な吹出パターンが容易に得られ、空気調和効果を大幅に向上させられるという効果を有する。
【００３５】
また、本発明によれば、案内部支持体の取付孔を複数列の千鳥状配置とし、気流案内部がそれぞれ互い違いに配置されて空気調和用気体を吹出すことにより、気流案内部から吹出される気流が別の気流案内部からの気流と互いに干渉しにくく、空気調和効果を最大限発揮させられると共に、案内部支持体と額縁部の隙間部分からの気流がいずれかの気流案内部と干渉してこの気流案内部から先の案内部支持体表面に沿って進めなくなっても、隙間部分のいずれか他の位置から吹出した気流が互い違いに並んだ気流案内部の間を通って案内部支持体表面に沿って進むこととなり、いずれの案内部支持体表面にももれなく隙間部分からの気流を到達させられ、案内部支持体表面への空気調和対象空間内のより暖かい気体の接触を確実に防いで結露を防止できるという効果を有する。また、千鳥状配置とすることで吹出口装置の幅を狭くしつつ気流案内部の数を最大限設定することができ、所定の空気調和効果を維持できるという効果を有する。
【００３６】
また、本発明によれば、断熱カバーが開口枠体の額縁部に取付けられ、額縁部表面を覆うことにより、気流案内部からの空気調和用気体吹出しに伴って誘引される空気調和対象空間内のより暖かい気体と額縁部との直接の接触が防げ、額縁部が冷却されて温度が低下した場合でも、額縁部表面に暖かい誘引気体を接触させず結露を発生させないという効果を有する。

BACKGROUND OF THE INVENTION
The present invention relates to a blowout device that blows out supplied conditioned air to an indoor space that is an air conditioning target, and particularly relates to a blowout device that can prevent condensation with a simple structure.
[0002]
[Prior art]
In a blowout device that is arranged on the ceiling or wall surface of an indoor space that is subject to air conditioning and blows out conditioned air, a portion facing the indoor space of the blowout device is cooled by the cold air that is blown out during cooling. In some cases, the indoor warm air that has been attracted comes into contact with these parts to cause condensation. For this reason, conventionally, various air outlet devices for preventing this dew condensation have been used, and an example of such a conventional air outlet device is shown in FIG. FIG. 5 is a schematic cross-sectional view of a conventional outlet device.
[0003]
In FIG. 5, the conventional outlet device 100 is attached to the ceiling 50, takes in conditioned air supplied from an air conditioner (not shown), and distributes the conditioned air to the indoor space side that is the target of air conditioning. An opening frame body 110 having an opening region 111 to be formed, a plurality of heat insulating covers 120 formed of a heat insulating material and covering the indoor space side of the opening frame body 110 by engaging with the opening frame body 110, and the opening frame body 110 is configured to include a plurality of wind direction adjusting bodies 130 that are rotatably disposed on 110 and adjust the direction in which conditioned air is blown out.
[0004]
In the conventional air outlet apparatus based on the said structure, each wind direction adjustment body 130 arrange | positioned at the opening frame 110 is rotated suitably, and the low temperature conditioned air supplied from an air conditioner (illustration omitted) is opened. The air is blown into the room as primary air A from the region 111. Each part of the opening frame 110 is cooled by the cool air of the primary air A.

The opening frame body 2, the heat insulating material 3 disposed so as to cover the inner and outer peripheral surfaces of the opening frame body 2, and a substantially plate disposed inside the opening area of the opening frame body 2 and covering the opening area It is a structure provided with the guide part support body 4 of a solid body, and the several airflow guide part 5 which is rotatably attached to the said guide part support body 4, and blows off airflow in the said indoor space.
[0015]
The opening frame 2 is formed as a frame-like body having an elongated rectangular opening region 2a inside as a line-type outlet, and a frame portion 2b having a predetermined width is formed at a lower end portion on the indoor space side, The open area 2a is communicated with the duct 51 in the ceiling 50 to take in conditioned air and distribute this conditioned air to the indoor space side. On the inner peripheral side facing the opening region 2a of the opening frame body 2 and the outer peripheral side position corresponding thereto, a heat insulating material 3 having a predetermined thickness is disposed along the surface. In addition, although the opening frame body 2 in this embodiment is formed by combining two frame-shaped members, the opening area side portion and the opening area outside portion of the frame portion 2b are separate members. Instead, it may be configured to be integrally formed as an opening frame.
[0016]
The guide portion support body 4 is formed of an elongated rectangular substantially plate-like body that is substantially equal to the transverse cross section of the opening region 2a of the opening frame body 2, and a circular mounting hole 4a is formed in the substantially plate-like body. A plurality of slit-shaped opening holes 4b are formed in a predetermined position at each edge portion of the substantially plate-like body in parallel with each outer periphery of the substantially plate-like body. It is attached via a heat insulating material 3 to a predetermined location inside the opening frame 2 that is a predetermined distance away from the frame 2b of the frame 2 on the upstream side, and there is a gap between the edge and the opening region side of the frame 2b. In this configuration, the portion 6 is generated. By arranging the mounting holes 4a in a staggered manner, a large number of air flow guide portions 5 can be disposed even if the width of the air outlet device is narrowed, and a sufficient air conditioning effect can be obtained. On the other hand, the opening hole 4b is formed in an edge portion that overlaps the opening region side portion of the frame portion 2b when attached to the opening frame 2 and does not face the indoor space side, and guides through the opening hole 4b.

It blows out along the support body 4 surface (refer FIG. 2), passes along the airflow guide parts 5 located in a line, and advances along the guide part support body 4 surface (refer FIG. 1). Among the surfaces of the guide support 4, there is an air flow of conditioned air blown out from the air flow guide 5 at the downstream portion of the air flow guide 5. On the other surfaces of the guide support 4, the gap 6 Since the airflow blown out from the air reaches without any leakage, the contact of the secondary air B with the surface of the guide support 4 is hindered, and condensation on this portion can be reliably prevented. In addition, in the frame portion 2b, the opening frame body 2 is not cooled due to the presence of the heat insulating material 3, and the frame portion 2b maintains a temperature substantially equal to the indoor space. Therefore, the secondary air B attracted to the surface of the frame portion 2b. Condensation does not occur even when touched.
[0020]

The frame part 2b of 2 is not cooled by the heat insulating material 3, and maintains a state close to the room temperature so that no dew condensation occurs on the surface.
[0021]
(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. 4 shows a schematic cross-sectional view of the outlet device according to the present embodiment.
[0022]
In FIG. 4, the air outlet device 1 according to the present embodiment shares the opening frame body 2, the heat insulating material 3, the guide portion support body 4, and the airflow guide portion 5 as in the first embodiment. On the other hand, as a different point, it is made of a heat insulating material, and the inner peripheral projection piece 7a is in close contact with the inner peripheral side of the frame portion 2b in the opening frame 2, and the outer peripheral projection on the outer peripheral side of the frame portion 2b. The piece 7b is intimately coupled, and has a configuration including a heat insulating cover 7 that is disposed in a sealed state with a gap 8 between the frame portion 2b and the indoor side surface.
[0023]
The said heat insulation cover 7 is a structure formed in the rectangular flat plate shape which covers the indoor space side of the frame part 2b. The heat insulating cover 7 is attached by pressing and pressing into the frame portion 2b by one-touch by the elastic force of the heat insulating cover 7 itself and the engagement of the outer peripheral engagement piece 7a with the outer peripheral edge of the frame portion 2b.

Then, although condensation occurs, the heat insulating cover 7 is disposed on the indoor surface of the frame portion 2b so that there is no contact with the secondary air B, and the air in a sealed state is provided between the frame portion 2b and the heat insulating cover 7. Since the gap 8 between the layers is formed, the heat conduction between the cooled frame portion 2b and the heat insulating cover 7 hardly occurs, and the heat insulating cover 7 is kept in a heat insulating state with respect to the frame portion 2b. . For this reason, the surface part of the heat insulating cover 7 can be kept close to the room temperature without being cooled, and condensation can be reliably prevented even on the surface of the heat insulating cover 7 in contact with the secondary air B.
[0026]
As described above, in the air outlet device according to the present embodiment, as with the first embodiment, it is possible to reliably prevent condensation on the surface of the guide support 4 and to maintain a state that is hardly cooled and is close to the room temperature.

Moreover, since the closed gap 8 is formed between the heat insulating cover 7 and the frame portion 2b, the temperature drop of the heat insulating cover 7 is suppressed as much as possible by the air layer interposed in the gap 8, and the heat insulating cover 7 Condensation on the surface can be reliably prevented.
[0027]
In the air outlet device according to the second embodiment, the heat insulating cover 7 is configured to form a gap 8 with the surface of the frame portion 2b in the attached state, but is sealed inside the heat insulating cover 7 itself. Even if the frame portion 2b is excessively cooled, the surface portion of the heat insulating cover 7 is reliably insulated across the gas layer in the hollow portion, and is almost the same as the room temperature. The state is maintained, and the temperature drop on the indoor space side surface of the heat insulating cover 7 can be surely prevented, and the occurrence of condensation on the surface of the heat insulating cover 7 can be more reliably prevented.
[0028]
Further, in the blowout device according to each of the first and second embodiments, the gap portion 6 between the guide portion support body 4 and the frame portion 2b of the opening frame body 2 is located upstream of the guide portion support body 4. In order to communicate with the opening region 2a on the side, a slit-like opening hole 4b is formed in the edge portion of the guide portion support body 4, but in addition to this, the outer peripheral portion of the guide portion support body 4 and the inside of the opening frame body 2 It can also be set as the structure which provides the predetermined ventilation area | region which lets conditioned air pass between the heat insulating materials of circumference | surroundings, and the conditioned air which passed this ventilation area blows off along the guide part support body 4 surface from the clearance gap part 6. FIG. Thus, as in the above-described embodiments, the contact between the secondary air attracted as the conditioned air is blown out and the cooled guide part support 4 can be prevented, and condensation on the surface of the guide part support 4 can be reliably prevented.
[0029]
Moreover, in the blower outlet apparatus which concerns on the said 1st and 2nd embodiment, it is the structure which forms the opening area | region 2a of the opening frame 2 and the guide part support body 4 in the shape of an elongate rectangle as a line type blower outlet. However, the present invention is not limited to this, and a configuration in which the shape is formed in a square shape or a round shape can be adopted, and an appropriate shape can be selected according to the air-conditioning application and the design in the indoor space. In addition, the airflow guide 5 is not limited to the two rows of staggered arrangement in the longitudinal direction of the guide support 4, but is arranged in a vertical and horizontal alignment state, or is densely arranged in the center of the guide support 4. You can also
[0030]
Furthermore, in the air outlet apparatus according to each of the first and second embodiments, the opening frame 2 is formed as a frame having only one opening region 2a on the inside, and the guide support 4 Although it is set as the structure which blows off conditioned air along the guide part support body 4 surface through the clearance gap part 6 between the frame parts 2b of the opening frame 2, other than this, an opening frame is fixed to the opening of a ceiling. It has a double structure consisting of an outer frame and an inner frame that supports the guide support, and a separate opening area is provided between the outer frame and the inner frame to allow conditioned air to pass through. It can also be set as the structure which blows off air to the guide part support body center side in a substantially horizontal direction, and it can prevent the condensation to the part which faces the room inner side of a blower outlet apparatus reliably like the said each embodiment.
