以下、本発明に係る実施の形態1における空気調和機について説明する。図1はこの発明の実施の形態1に示す空気調和機の外観斜視図である。
さらに空気調和機100の内部には、ファン10としてターボファン、ファン10を回動するファンモータ11を有し、ファン10の外周側を囲むように略四角形の熱交換器12が立設し、熱交換器12の下方には冷房運転や除湿運転時に熱交換器12で空気が凝縮し結露した凝縮水を受けるドレンパン14が設置されている。ファン10から熱交換器12までのファン吹出風路13は、ドレンパン14と本体天板8a、側板8bに沿う様に形成された断熱材9とで形成されたエルボ型のユニットエルボ風路15を介して、化粧パネル2の吹出口6に連通している。
また、吹出口6は略長方形形状で、長辺側が吸込グリルの一辺と平行となるように形成され、吹出口6は吸込グリル4側の壁面である内側風路壁16と、吸込グリル4から遠い方の外側風路壁17とにより構成されている。図2、3の断面図のように、内側風路壁16、外側風路壁17が吸込グリル4に対しユニット外側へ向くように湾曲した風路形状を形成している。内側風路壁16が略凹形状の曲面をしており、外側風路壁17が略凸形状の曲面をしている。これら内側風路壁16と外側風路壁17が対向して設けられて吹出口6が形成されている。
また、ベルマウス18はフィルタ5からファン10への風路を形成し、吸込口3、吸込グリル4から吸入された吸入空気F1はフィルタ5を通過した後ベルマウス18を通ってファン10によってファン吹出風路13に送風される。ファン吹出風路13に送風された空気は熱交換器12で熱交換される。特に、本実施の形態1では熱交換器12には図示しない冷媒回路の膨張弁を通過した低温の冷媒が流れているものとし、空気調和機100が設置されている室内の空気を冷却するものとする。熱交換器12を通過した空気は熱が奪われて低温の空気となって、ユニットエルボ風路15を通過する。
以上の結果、高品質で信頼性が高く、快適性が向上した空気調和機が得られる。
実施の形態1では、図5、図7で内側風路壁凹部開始端19aと外側風路壁凹部開始端20aがそれぞれ内側風路壁16と外側風路壁17の長手方向と平行に設けられている構成について説明したが、本実施の形態2では内側風路壁凹部開始端と外側風路壁凹部開始端に傾斜を設けた構成について説明する。尚、本実施の形態2において実施の形態1と同一構成部分には同一符号を付し説明は省略する。
図8は本実施の形態2における内側風路壁21の断面図である。内側風路壁21は実施の形態1と同様に、吹出口6の長手方向において、中央部が端部よりも盛り上がった形状をしている。つまり、内側風路壁21の左右の両端部分が内側風路壁端部21a、内側風路壁21の中央部分が内側風路壁中央部21bである。内側風路壁21の下流側の下辺の内側風路壁下流側端部21cは内側風路壁21の長手方向と平行で略直線状であり、内側風路壁21の長手方向の左右の内側風路壁端部21aが内側風路壁中央部21bに対して吹出口6の短手方向に対して風路が一部拡大するような内側風路壁凹部22が形成されている。内側風路壁凹部22の上流側の端辺である内側風路壁凹部開始端22aは内側風路壁21の長手方向に対して傾斜し、内側風路壁21の長手方向の端に向かうにつれて、内側風路壁凹部開始端22aと内側風路壁凹部終端22bとの間隔が狭くなっている。内側風路壁端部21aと内側風路壁中央部21bの間には段差があり、内側風路壁凹部側壁22cがその段差部を形成している。
実施の形態1、2では空気調和機の一例としてファンとしてターボファンを用いターボファン下流側に熱交換器を配設した天井埋込形空気調和機について述べたが、本願発明はこれに限定されるものではなく、本実施の形態3で説明する天井面に面して配設されるクロスフローファンを搭載した天井埋込形空気調和機に対しても適用することができる。
