Description
これは、フィルタが収縮可能に形成され、作業者がある程度の任意の大きさに縮めることができるような構成となっており、着脱の際には、その着脱経路の一部に含まれる配管を回避することが可能であることを前提としたものである。
内部に空気通路を有するケースと、前記空気通路に配置されて該空気通路を流れる送風空気の熱と熱媒体の熱とを交換する熱交換器と、前記熱交換器に前記熱媒体を供給および回収する複数の配管と、前記空気通路に配置され前記ケースと着脱可能とされたフィルタと、を備える車両用空調装置であって、
前記複数の配管は前記フィルタの着脱経路に含まれる重複区間をそれぞれ有し、前記複数の配管の重複区間は前記フィルタの着脱方向と並行するように配設されてなるものである。
なお、以下に説明する部材、配置等は本発明を限定するものではなく、本発明の趣旨の範囲内で種々改変することができるものである。
本発明の実施の形態における車両用空調装置1は、車両のセンターコンソール部に搭載される縦型フルセンター置きタイプと称されるもので、車両のエンジンルームと車室を区画する隔壁よりも車室側に配され、インテークユニット2と空調ユニット3とを主たる構成要素として構成されている。
すなわち、まず、エンジンルーム等の空調ユニット3の外部には、冷却用熱交換器7へ冷媒の供給、回収を行うための冷媒供給用外部配管及び冷媒回収用外部配管(図示せず)が設けられている。空調ユニット3の車両前方向に面する適宜な部位には、ブロック式の膨張装置70が設けられ、前記した冷媒供給用外部配管と冷媒回収用外部配管とが接続される。膨張装置70は、冷媒供給用サブ配管71と冷媒回収用サブ配管72とにより、冷却用熱交換器7と接続される。
すなわち、まず、エンジンルーム等の空調ユニット3の外部には、加熱用熱交換器9への温水の供給、回収を行うための温水供給用外部配管及び温水回収用外部配管(図示せず)が設けられている。空調ユニット3の車両前方向に面する適宜な部位には、温水供給用サブ配管(図示せず)の一方側端部が配設されて、温水供給用外部配管と接続される。同様に、空調ユニット3の車両前方向に面する適宜な部位に、温水回収用サブ配管(図示せず)の一方の端部が配置され、温水回収用外部配管と接続される。
上述のエアガイド壁17の上端部に位置するエアミックスチャンバ13の領域に面して、フット側通路36に向かう空気の風量を調節するフットドア22が回動可能に設けられている。
そして、第1のエアミックスドア10及びエアガイド壁17の上端部よりも車両上方となるエアミックスチャンバ13の領域において、デフベント側通路37へ向かう空気量を調節するデフベント通路側ドア18が適宜な位置に、回動可能に配設されている。
本発明の実施の形態においては、上述したフットドア22、デフベント通路側ドア18、及び、デフベント切換ドア19により、各吹出用開口部14,15,16への空気の供給量の割合を調整するモードドアが構成されたものとなっている。
さらに、インテークユニット2は、外気導入口21と内気導入口60が空調ケース5に対して開口し、各導入口21,60は、空調ケース5に形成された空気取入口に向かって延びる通路26,20を有している。
そして、外気導入(FRESH)モードと内気循環(REC)モードとのモード切換制御は、例えば、ロータリ式の内外気切換ドア25を適宜回動することで可能となっている。
本発明の実施の形態におけるエアフィルタ8は、その側面が短冊状の外形を有しており、図1においては、その一方の側面が示されている。

冷却用熱交換器7に接続された冷媒供給用サブ配管71及び冷媒回収用サブ配管72は、冷却用熱交換器7の一方の側面7aに接続された部分から適宜な長さに渡って側面7aに対してほぼ垂直に延び、しかる後、いずれも車両前方向へ直角に折り曲げられて、エアフィルタ8と空調ケース5の間の適宜な位置までほぼ直線状に延びている(図1参照)。
これに対して、従来装置にあっては、冷媒供給用サブ配管71が図2において点線円で示されたように、冷媒回収用サブ配管72の下側に配設された構造であった。そのため、エアフィルタ8の着脱に際しては、エアフィルタ8の上面から冷媒供給用サブ配管71の下面までの寸法(図2においてd1で表された長さ程度)だけ、エアフィルタ8を、折り目方向(図2において紙面上下方向)で縮めて着脱作業を行わなければなかった。
