Description

【０００１】
【発明の属する技術分野】
本発明は、横断流送風機型送風回路を備えた薄型タイプの空気調和機に関するものである。
【０００２】
【従来の技術】
近年、室内などに用いられる空気調和機は空気調和性能の向上と共に機器の小型化をはかった物がより多く用いられてきている。
【０００３】
従来、この種の横断流送風機型送風回路が用いられている空気調和機は、例えば特開平９−１６６３５３号公報に記載されているように、図１３に示すような構成になっている。図１３（ａ）は下方から空気調和機を見上げた場合を示し、（ｂ）はその空気調和機の垂直方向の横断面図である。
【０００４】
同図において、室内ユニット本体１０１は、居室内の天井（図示せず）と２方向の壁１０２ａ、１０２ｂとのコーナー部に密着して取り付けられ、室内ユニット本体下方部に室内空気の吸い込み口である吸い込みグリル１０３を有し、正面の円弧面の部分に吹き出し口１０４を有した略４分の１円弧の扇形台形状をしている。
【０００５】
また室内ユニット本体１０１内には、クロスフローファン（横断流送風機）１０５と、この風上側に逆Ｌ字状の熱交換器１０６を有し、熱交換器１０６の下方に水受け皿１０７を形成したスタビライザ１０８を具備している。そして、クロスフローファン１０５が回転すると、図１３に示す矢印方向の送風作用を生じ、これによって室内空気は下方部の吸い込みグリル１０３から吸い込まれ、熱交換器１０６により熱交換された後、吹き出し口１０４より吹き出される。尚、１０９は内部接続配管、１１０は風向変更装置である。
【０００６】
【発明が解決しようとする課題】
しかしながら、上記従来の構成では、クロスフローファン１０５、熱交換器１０６及び吹き出し口１０４の構成と配置が適切でないため、室内ユニット本体１０１の大きさの割には期待された風量性能が得られなかった。また、熱交換器１０６は略水平部の熱交換器に付着した凝縮水が滴下しがたく、この為著しく通風抵抗を増加させ風量性能を劣化させるという課題と共に、クロスフローファン１０５の流入域の風速分布が均一でなく騒音を上昇させるという課題があった。
【０００７】
本発明は、このような従来の課題を解決するものであり、本体のコンパクト化、風量性能の向上及び低騒音化をはかった空気調和機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】
上記課題を解決するために本発明は、下部に吸い込み口部を、前部または前部下方に吹き出し部を有する筺体の内部に略水平方向に回転軸をもつクロスフローファンを設け、前記吹き出し口部より勾配を有して立ち上がり峰部が前記クロスフローファンに接近、対向するように配設したスタビライザと、前記クロスフローファンの上部側に設けられ、前記スタビライザと通風路を形成するリアガイダとを備え、前記クロスフローファンの風上側には前記クロスフローファンを受けるように略Ｖ字形に配置したメイン熱交換器と前記メイン熱交換器とクロスフローファンの間に配置したサブ熱交換器と、前記クロスフローファンの下方でかつ前記メイン熱交換器の下側に水受け皿とを設けたことにより、高さを低くした筺体の空間に熱交換器を有効に配置することができ、かつクロスフローファンの流入域の風速分布を略均一にすることができる。この為、室内ユニットのコンパクト化と風量性能の向上をはかることができるものである。

【００１７】
請求項７に記載の発明は、サブ熱交換器のＵベンド、ヘアピン、熱交換器のリードパイプがメイン熱交換器下流側の送風回路内に配置することにより、ヘアピン、Ｕベンド、更には熱交換器に接続されたリードパイプからの放熱、吸熱による熱交換能力分も能力アップすることができる。

請求項１０に記載の発明は、略Ｖ字形に配置した熱交換器の最上部にもう一つの熱交換器を鉛直方向または上端部がクロスフローファンに向かって傾斜するように配置することにより、筺体の奥行きをよりコンパクトにできる。
【００２４】
以下本発明の実施形態について図面を参照して説明する。
【００２５】
（実施形態１）
図１は本発明の一実施形態における空気調和機本体１を居室内に設置した場合の斜視図である。図２は同空気調和機の横断面図である。
【００２６】
図１，２において、１は壁２に設置された空気調和機本体（以下、筺体という）であり、筺体１は下面部に吸い込みグリル３を介した吸い込み口部４と前部下方に吹き出し口部５とを有し、内部に水平方向に回転軸をもつクロスフローファン６を有し、その風上側にメイン熱交換器７を、風下側にスタビライザ８を有している。スタビライザ８は吹き出し口部５よりクロスフローファン６に向かって勾配を有して立ち上がり、その峰部８ａがクロスフローファン６に接近、対向するようにしている。また、クロスフローファン６の上部側には吹き出し口部５にかけてリアガイダ９を有し、スタビライザ８とリアガイダ９によって通風回路（ディフューザ）を形成している。
【００２７】
メイン熱交換器７は、第１，第２，第３の熱交換器７ａ、７ｂ、７ｃに３分割して、クロスフローファン６を囲うように設置すると共に、第１，第２のメイン熱交換器７ａ，７ｂはクロスフローファン６の下方に略Ｖ字形に配置し、第１の熱交換器７ａの上端部をスタイビライザ８の峰部８ａに隣接させている。
【００２８】
また、第３の熱交換器７ｃは第２の熱交換器７ｂの上端部に立設するように配置している。１０はメイン熱交換器７の下流側で、クロスフローファン６とメイン熱交換器７の間にメイン熱交換器７に隣接して設けられたサブ熱交換器である。１１はメイン熱交換器７，サブ熱交換器１０の凝縮水を受ける水受け皿、１２は、熱交換器７に流入する空気中のほこりや汚れた空気を浄化するフィルター、１３は第１，第２のメイン熱交換器７からの結露水の落下を受ける樋である。
【００２９】
上記構成において、クロスフローファン６を図２に示す矢印方向に回転すると、筺体下面の吸い込みグリル３より流入した空気は吸い込み口部４より水受け皿１１外周部を通ってメイン熱交換器７、サブ熱交換器１０に吸い込まれ、熱交換されて吹き出し口部５より斜め下方に吹き出される。このときメイン熱交換器７，サブ熱交換器１０で生じた凝縮水は、略Ｖ字形に傾斜した第１，第２のメイン熱交換器７ａ，７ｂより水受け皿１１に流れ落ちる。この為、メイン熱交換器７からの滴下水を水受け皿１１で確実に受けることができるとともに、吸い込み空気が水受け皿１１の外周全域より容易にメイン熱交換器７に吸い込まれ、吸い込み抵抗を減少させると共にサブ熱交換器１０によるメイン熱交換器７の風速分布の改善、熱交換器能力アップ等をはかることができる。
【００３０】
また、メイン熱交換器７を略Ｖ字形にしてクロスフローファン６を囲うように配置し、メイン熱交換器７とクロスフローファン６の間にサブ熱交換器１０を配置し、下方に吸い込み口部３を設けることにより、筺体１を薄型コンパクトにしている。
【００３１】
さらには、サブ熱交換器１０の形状をメイン熱交換器７と異なる形状にしており、風速分布の不均一（風速が速い）な部分にサブ熱交換器１０を配置し風速分布の均一化をはかると共に本体構成上の熱交換器レイアウトを容易化し、更なるコンパクト化、熱交換器能力の拡大、送風性能の向上をはかっている。
【００３２】
さらには、サブ熱交換器１０のフィン幅Ｌ１をメイン熱交換器７のフィン幅Ｌ２より小さく（Ｌ１＜Ｌ２）することにより、サブ熱交換器１０の通風抵抗を低減すると共にクロスフローファン６とサブ熱交換器１０との距離Ｌ３を広くとることができ、送風性能の向上をはかっている。
【００３３】
さらには、サブ熱交換器１０の銅管段ピッチＬ４をメイン熱交換器７の銅管段ピッチＬ５より小さく（Ｌ４＜Ｌ５）とすることにより、同一熱交換器容積で熱交換器能力をアップすることができると共にメイン熱交換器７の銅管千鳥パターンからの流路をサブ熱交換器１０で整流することができ送風性能を向上させている。
【００３４】
図３は、本発明の空気調和機１の熱交換器ブロックの外観斜視図である。同図において、７ｄは、メイン熱交換器７のフィン、１０ｅはサブ熱交換器１０のフィンであり、Ｐ１はサブ熱交換器１０のフィンピッチ、Ｐ２はメイン熱交換器７のフィンピッチである。サブ熱交換器の１０のフィンピッチＰ１をメイン熱交換器７のフィンピッチＰ２より大きくする（Ｐ１＞Ｐ２）ことにより、サブ熱交換器１０の通風抵抗を減少させ、サブ熱交換器１０搭載の送風性能を向上させている。
【００３５】
さらには、サブ熱交換器１０の長手方向寸法Ｌ６をメイン熱交換器７の寸法Ｌ７より小さく（Ｌ６＜Ｌ７）することにより、メイン熱交換器７の下流側送風回路内にサブ熱交換器１０のヘアピン１０ａ、Ｕベンド１０ｂの銅管を配置でき、ヘアピン１０ａ、Ｕベンド１０ｂからの放熱、吸熱による熱交換能力分をアップし熱交換器効率を上げることができる。
【００３６】
図４は、メイン熱交換器７及びサブ熱交換器１０のフィン形状を示したもので図中、７ｄはメイン熱交換器７のフィン、７ｅはフィン７ｄに設けられた複数のスリットである。１０ｅはサブ熱交換器１０のフィン、１０ｆはフィン１０ｅに設けられたスリットであり、サブ熱交換器１０のスリット高さｔ２をメイン熱交換器７のスリット高さｔ１よりも低く（ｔ２＜ｔ１）することにより、サブ熱交換器１０の通風抵抗を減少させ、サブ熱交換器１０搭載の送風性能を向上させている。
【００３７】
さらには、メイン熱交換器７のフィン７ｄのスリット形状７ｅをサブ熱交換器１０のフィン１０ｅのスリット形状１０ｆと異なった形状にすることによりメイン熱交換器７からサブ熱交換器１０を通りクロスフローファン６への風の流れが整流できると共に、サブ熱交換器１０の通風抵抗を減少させ、サブ熱交換器搭載による送風性能の向上をはかっている。
【００３８】
図５は図2を反対側（Uベンド側）から見た断面図で、図３および図５において、サブ熱交換器１０のヘアピン１０ａ、Ｕベンド１０ｂ、熱交換器１０へのリードパイプ１０ｃ，１０ｄを送風回路内に配置することにより、ヘアピン１０ａ、Ｕベンド１０ｂ、リードパイプ１０ｃ，１０ｄからの放熱、吸熱による熱交換能力分をアップし熱交換器効率を上げることができる。
【００３９】
さらには、凝縮器時の熱交換器７，１０への冷媒の入り口配管１０ｄをサブ熱交換器１０に設けたことにより、暖房時に温度の高い冷媒がサブ熱交換器１０に入り、サブ熱交換器１０のヘアピン１０ａ、Ｕベンド１０ｂ、リードパイプ１０ｄからの熱交換器効率も更にアップすることができる。
【００４０】
（実施の形態２）
図６（ａ）、（ｂ）は本発明の実施の形態２の筺体を壁に設置した状態の外観斜視図とその下面図である。断面図は実施の形態１の図２と同じである。
【００４１】
実施の形態１と異なるのは、筺体１の形状を略扇形台（略１／４円柱）にした点であり、実施の形態１と同一のものは同番号を付し説明を省略する。すなわち、図６（ａ）、（ｂ）に示すように筺体１を室内（被空調空間）の壁面２ａ、２ｂに対向して取り付けられる２辺を持つように、平面形状を略扇形にしたものである。なお、図３に示すスタビライザ８とリアガイダ９とで形成された通風路の長さを円弧状の吹き出し口部５に対応させて、中央部から端部にかけて徐々に短くしている。
【００４２】
図７（ａ）、（ｂ）は他の例の外観斜視図とその下面図で、下面（平面）断面形状を略２等辺３角形にしたものである。なお、その他に平面外形形状を図８（ａ）、（ｂ）、（ｃ）、（ｄ）に示すような略扇形の形状にしても良い。
【００４３】
（実施の形態３）
図９は本発明の実施の形態３の筺体を壁に設置した状態の外観斜視図、図１１は同筺体を正面（前面）から見た要部部分断面図である。
【００４４】
図１０に示すように、水受け皿１１は縁にツバ（皿壁）を有し、クロスフローファン６の軸方向のつば側部１１ａは熱交換器７の幅より大きくして上方に立設させ、筺体１とつば側部１１ａとの間に吸い込み口部４からの空気を矢印のように熱交換器７に導く側部吸い込み風路１４を形成する。なお、１５はその風路を形成するためのガイド部材である。この構成によって、水受け皿１１の側方サイドからも吸い込み空気を熱交換器７に円滑に供給することができ、送風性能の向上をはかることができる。
【００４５】
（実施の形態４）
図１１は本発明の実施の形態４を示す筺体の横断面図で、実施の形態１と異なるのは、メイン熱交換器７の第１、第２の熱交換器７ａ，７ｂの両下端部を水平方向に離して配置し、その間にサブ熱交換器１０の下端部がメイン熱交換器７ａの下端部と重なるように配設するようにした点である。
【００４６】
これにより、熱交換器７及びサブ熱交換器１０の下部からの吸い込み面積拡大による送風性能向上と筺体の高さ方向の寸法を小さくでき、更に低背化をはかることができる。
【００４７】
さらには、略Ｖ字形に配置したメイン熱交換器７の第１、第２の熱交換器７ａ、７ｂが水平方向となす角度θ１、θ２をそれぞれ４０゜以上とし、これによってメイン熱交換器７の第１、第２の熱交７ａ，７ｂ及びサブ熱交換器１０に付着した凝縮水を円滑に下方に流すことができる。この角度θ１、θ２は９０゜とするのが凝縮水の流れからすれば最善であるのは言うまでもないが、４０゜を下回ると凝縮水の表面張力が影響し、凝縮水の流れが悪くなる。
【００４８】
（実施の形態５）
図１２は本発明の実施の形態４を示す筺体の横断面図で、実施の形態１と異なるのは第２のメイン熱交換器７ｂの最上部にもう一つの第３の熱交換器７ｃを鉛直方向ないしは上端部がクロスフローファン６に向かって傾斜するように設置した点であり、これにより筺体１の奥行きをよりコンパクトにすることができる。
