前記エアミックスドア(24、24A)は、前記ヒータ(23)を迂回する空気の流れ方向を基準として、略直交するように延び前記ケース(21、21C)に回転可能に設けられている回転軸(31)と、前記回転軸(31)から延出し前記回転軸(31)よりも上流側を移動可能な第1閉塞板(32)と、前記回転軸(31)から前記第1閉塞板(32)とは略反対方向へ延出する第2閉塞板(33)と、を有するバタフライドア部(30)を含み、
前記バタフライドア部(30)は、前記ヒータ(23)を迂回する空気の比率を最大とするフルクール位置と、前記ヒータ(23)を通過する空気の比率を最大とするフルホット位置と、前記フルクール位置と前記フルホット位置の間の位置であって前記エバポレータ(22)を通過した空気の一部が前記ヒータ(23)を迂回する温度調和位置と、のいずれかに位置するよう調節され、
前記回転軸(31)と前記ヒータ(23)との間には、前記バタフライドア部(30)が前記温度調和位置にあるとき、前記エバポレータ(22)を通過した空気の一部が通過するヒータ・ドア間流路(R2)が形成されており、
前記バタフライドア部(30)には、前記ヒータ・ドア間流路(R2)を流れる空気を所定の方向に導くガイド部(41)が設けられていることを特徴とする車両用エアコン装置が提供される。
図1を参照する。車両用エアコン装置10(以下、「エアコン装置10」と略記する。)は、車室の前部に左右方向に延びるように配置される。エアコン装置10は、車室内及び/又は車外の空気を取り入れ送風することが可能な送風部11と、この送風部11から送られた送風空気を所定の温度に調節可能な温度調節部20と、を有する。
次に、実施例2によるエアコン装置10Aを図面に基づいて説明する。
次に、実施例3によるエアコン装置10Bを図面に基づいて説明する。
次に、実施例4によるエアコン装置10Cを図面に基づいて説明する。
