Description

【０００１】
【発明の属する技術分野】
本発明は、空気通路の開口部に沿って摺動するスライドドアにより開口部を開閉する空気通路開閉装置およびこの空気通路開閉装置を備える車両用空調装置に関するものである。
【０００２】
【従来の技術】
従来、車両用空調装置においては空気通路の開口部に沿って摺動するスライドドアにより開口部を開閉する空気通路開閉装置が知られている。例えば、冷風と温風の風量割合を調整するエアミックスドアや、複数の吹出開口部を開閉する吹出モードドアをスライドドアにより構成することが知られている。
【０００３】
【発明が解決しようとする課題】
しかし、従来技術では、エアミックスドアや吹出モードドアをスライドドアにより構成する場合に、この複数のスライドドアの作動空間をそれぞれ別部位に独立に形成しているので、車両用空調装置の体格の小型化が困難であった。
【０００４】
本発明は上記点に鑑みて、複数のスライドドアを用いる空気通路開閉装置および車両用空調装置において、体格の小型化を図ることを目的とする。
【０００５】
また、本発明は、複数のスライドドアを可撓性を有する膜状部材により構成する空気通路開閉装置および車両用空調装置において、体格の小型化を図ることを目的とする。
【００１０】
【課題を解決するための手段】
上記目的を達成するため、請求項１に記載の発明では、筒状のケース部材（３１）と、筒状のケース部材（３１）の周方向に配置された複数の開口部（３６〜３９）と、筒状のケース部材（３１）内にて筒状の径方向に積層配置され、可撓性を有する複数の膜状部材（３２、３３）とを備え、
複数の膜状部材（３２、３３）が複数の開口部（３６〜３９）に沿って回転変位することにより複数の開口部（３６〜３９）を開閉するようになっており、
さらに、複数の膜状部材（３２、３３）の少なくとも１つをループ状とした空気通路開閉装置を特徴とする。
【００１１】
これにより、複数の膜状部材（３２、３３）の回転変位により複数の開口部（３６〜３９）を開閉することができる。
ここで、膜状部材（３２、３３）はケース部材（３１）側の摺動経路に沿って柔軟に変形するので、ケース部材（３１）の筒形状に沿って膜状部材（３２、３３）を曲げ配置でき、剛体のスライドドアに比較して空気通路開閉装置の体格を効果的に小型化できる。
しかも、筒状のケース部材（３１）内に複数の膜状部材（３２、３３）を径方向に積層配置しているから、空気通路開閉装置の外形状を極めてコンパクトな筒形状にまとめることができ、空気通路開閉装置の体格をより効果的に小型化できる。
【００１２】
なお、請求項１におけるケース部材（３１）の「筒状」とは、円筒状の他に、長円状の筒形状等を包含している。
【００１３】
さらに、請求項１に記載の発明では、複数の膜状部材（３２、３３）の少なくとも１つをループ状にしているから、このループ状の膜状部材（３２、３３）に対して常に引っ張り力を作用させることができる。従って、ループ状の膜状部材（３２、３３）を比較的小さな駆動力にて確実に回転変位させることができる。
因みに、膜状部材の両端部を自由端として、膜状部材の中間部位に駆動力を加えて前後方向に往復動させる場合においては、膜状部材のうち駆動力の印加部位より進行方向の前方部位が引っ張り力でなく、押出力にて押し出されることになる。この押し出し部分では膜状部材の撓みが非常に発生しやすくなり、この撓みの発生により膜状部材の駆動力が増大するという不具合が生じる。
しかし、請求項１によると、複数の膜状部材（３２、３３）の少なくとも１つをループ状にして常に引っ張り力にて膜状部材（３２、３３）を回転変位させるから、比較的小さな駆動力にて確実に膜状部材（３２、３３）を変位させることができる。
【００１４】
請求項２に記載の発明では、請求項１において、ケース部材（３１）に、複数の膜状部材（３２、３３）の閉口部（３２３、３２４、３３３、３３４）をともに収納する共通の収納部（４１ａ、４２ａ）を形成したことを特徴とする。
【００１５】
これにより、複数の膜状部材（３２、３３）の閉口部を共通の収納部（４１ａ、４２ａ）に収納することができ、空気通路開閉装置の体格をより一層小型化できる。
【００１６】
請求項３に記載の発明では、請求項１または２において、複数の膜状部材（３２、３３）をそれぞれ独立に駆動する複数の駆動機構（４３、４４、４７、４８）を備え、複数の駆動機構（４３、４４、４７、４８）を複数の膜状部材（３２、３３）の内側領域に配置したことを特徴とする。
【００１７】
これにより、複数の駆動機構をも含めて空気通路開閉装置の体格を更に小型化できる。
請求項４に記載の発明では、筒状のケース部材（３１）と、
筒状のケース部材（３１）の周方向に配置された複数の開口部（３６〜３９）と、
筒状のケース部材（３１）内にて筒状の径方向に積層配置され、可撓性を有する複数の膜状部材（３２、３３）とを備え、
複数の膜状部材（３２、３３）が複数の開口部（３６〜３９）に沿って回転変位することにより複数の開口部（３６〜３９）を開閉するようになっており、
複数の膜状部材（３２、３３）をそれぞれ独立に駆動する複数の駆動機構（４３、４４、４７、４８）を備え、
複数の駆動機構（４３、４４、４７、４８）を複数の膜状部材（３２、３３）の内側領域に配置した空気通路開閉装置を特徴とする。
これによると、請求項１と同様に、可撓性の膜状部材（３２、３３）はケース部材（３１）側の摺動経路に沿って柔軟に変形するので、ケース部材（３１）の筒形状に沿って膜状部材（３２、３３）を曲げ配置でき、剛体のスライドドアに比較して空気通路開閉装置の体格を効果的に小型化できる。
しかも、筒状のケース部材（３１）内に複数の膜状部材（３２、３３）を径方向に積層配置しているから、空気通路開閉装置の外形状を極めてコンパクトな筒形状にまとめることができる。
さらには、複数の駆動機構を複数の膜状部材の内側領域に配置することで、複数の駆動機構をも含めて空気通路開閉装置の体格を小型化できる。以上のことが相俟って、空気通路開閉装置の体格を効果的に小型化できる。
【００１８】
請求項５に記載の発明では、請求項３または４において、複数の膜状部材（３２、３３）のうち、筒状の径方向の外側に配置される膜状部材（３３）の幅寸法を、筒状の径方向の内側に配置される膜状部材（３２）の幅寸法より大きくし、複数の駆動機構はそれぞれ駆動ギヤ（４７、４８）を有しており、筒状の径方向の外側に配置される膜状部材（３３）を回転変位させる駆動ギヤ（４８）を筒状の径方向の内側に配置される膜状部材（３２）の幅寸法の外側に配置し、筒状の径方向の内側に配置される膜状部材（３２）を回転変位させる駆動ギヤ（４７）を筒状の径方向の内側に配置される膜状部材（３２）の幅寸法の範囲内に配置することを特徴とする。
【００１９】
これにより、径方向に積層配置した複数の膜状部材（３２、３３）をその内側領域に配置した複数の駆動機構（４３、４４、４７、４８）にてギヤ駆動する場合に、筒状の径方向の外側に配置される膜状部材（３３）を、内側に配置される膜状部材（３２）との干渉を起こすことなく、円滑にギヤ駆動することができる。
【００２０】
請求項６に記載の発明では、車室内へ向かって流れる空気流れを制御する機構として、請求項１ないし５のいずれか１つに記載の空気通路開閉装置を備える車両用空調装置を特徴とする。
【００２１】
これにより、上述の空気通路開閉装置を用いて車両用空調装置の体格を効果的に小型化することができ、車両用空調装置の車両搭載性を向上できる。
【００２２】
請求項７に記載の発明では、車室内へ向かって流れる空気流れを制御する機構として、請求項１ないし５のいずれか１つに記載の空気通路開閉装置を備え、
複数の開口部として、冷風が流入する冷風入口（３６）と、温風が流入する温風入口（３７）と、車室内の複数部位に空気を吹き出す複数の吹出開口部（３８、３９）とを備え、
複数の膜状部材の１つ（３２）は、冷風入口（３６）と温風入口（３７）を開閉して冷風と温風の風量割合を調整するエアミックスドアであり、
複数の膜状部材の他の１つ（３３）は、複数の吹出開口部（３８、３９）を開閉して吹出モードを切り替える吹出モードドアであり、
冷風と温風の風量割合の調整により温度調整された空気を複数の吹出開口部（３８、３９）を通過して車室内へ吹き出す車両用空調装置を特徴とする。
【００２３】
請求項８に記載の発明では、車室内へ向かって流れる空気流れを制御する空気通路開閉装置に筒状のケース部材（３１）を備え、
筒状のケース部材（３１）の周方向に複数の開口部（３６〜３９）が配置され、
筒状のケース部材（３１）内には、可撓性を有する複数の膜状部材（３２、３３）が筒状の径方向に積層配置されており、
複数の膜状部材（３２、３３）が複数の開口部（３６〜３９）に沿って回転変位することにより複数の開口部（３６〜３９）を開閉するようになっており、
複数の開口部として、冷風が流入する冷風入口（３６）と、温風が流入する温風入口（３７）と、車室内の複数部位に空気を吹き出す複数の吹出開口部（３８、３９）とを備え、
複数の膜状部材の１つ（３２）は、冷風入口（３６）と温風入口（３７）を開閉して冷風と温風の風量割合を調整するエアミックスドアであり、
複数の膜状部材の他の１つ（３３）は、複数の吹出開口部（３８、３９）を開閉して吹出モードを切り替える吹出モードドアであり、
冷風と温風の風量割合の調整により温度調整された空気を複数の吹出開口部（３８、３９）を通過して車室内へ吹き出す車両用空調装置を特徴とする。
請求項７および請求項８に記載の発明によると、エアミックスドアと吹出モードドアの両者を１つの筒状のケース部材（３１）内に配置して、温度調整機構と吹出モード切替機構とを極めてコンパクトな体格にまとめることができる。
【００２４】
請求項９に記載の発明では、請求項７または８において、エアミックスドアを構成する膜状部材（３２）を筒状の径方向の内側に配置し、吹出モードドアを構成する膜状部材（３３）を筒状の径方向の外側に配置したことを特徴とする。
【００２５】
ところで、車室内へ向かって流れる空気流れに対してエアミックスドアを構成する膜状部材（３２）は上流側に位置し、吹出モードドアを構成する膜状部材（３３）は下流側に位置する。従って、エアミックスドアを構成する膜状部材（３２）を空気流れの風圧により筒状の径内方側へ変位させることができる。従って、膜状部材（３２）の内側にガイド壁（４０）を配置しておくことにより、このガイド壁（４０）に膜状部材（３２）を風圧により圧着して、冷風入口（３６）と温風入口（３７）を閉塞する時のシール作用を良好に発揮できる。
【００２６】
また、吹出モードドアを構成する膜状部材（３３）を空気流れの風圧により筒状の径外方側へ変位させて、筒状のケース部材（３１）の内壁面に膜状部材（３３）を風圧により圧着することができる。これにより、複数の吹出開口部（３８、３９）を閉塞する時のシール作用を膜状部材（３３）にて良好に発揮できる。
【００２７】
請求項１０に記載の発明では、請求項７ないし９のいずれか１つにおいて、エアミックスドアを構成する膜状部材（３２）に、冷風と温風の両方が通過する開口部（３２２）を備えることを特徴とする。
【００２８】
これにより、膜状部材（３２）では１つの開口部（３２２）内を冷風と温風が隣接して流れるから、冷風と温風が互いに離れて流れる場合に比して冷風と温風の混合性が向上し、車室内への吹出空気の温度バラツキを低減できる。
【００２９】
なお、上記各手段の括弧内の符号は、後述する実施形態に記載の具体的手段との対応関係を示すものである。
【００３０】
【発明の実施の形態】
以下、本発明の一実施形態を図に基づいて詳述する。図１、図２は本実施形態における空調ユニット１０部分の断面図であり、図１はフットモード時を示し、図２はフェイスモード時を示す。図３は本実施形態の要部である後席側制御機構を示し、図４は図３のＡ−Ａ断面図である。また、図５は後席エアミックス用ドア手段をなす後席エアミックス用膜状部材を示し、図６は後席吹出モード用ドア手段をなす後席吹出モード用膜状部材を示す。
【００３１】
本実施形態による車両用空調装置の通風系は、大別して、図示しない送風機ユニットと、空調ユニット１０との２つの部分に分かれている。送風機ユニットは車室内の計器盤下方部のうち、中央部から助手席側へオフセットして配置されており、これに対し、空調ユニット１０は車室内の計器盤内側のうち、車両幅（左右）方向の略中央部に配置されている。
【００３２】
送風機ユニットは周知のごとく内気（車室内空気）と外気（車室外空気）を切替導入する内外気切替箱と、この内外気切替箱を通して空気を吸入して送風する送風機（具体的には遠心式電動送風機）とから構成されている。
【００３３】
空調ユニット１０部は、１つの共通の空調ケース１１内に蒸発器１２とヒータコア１３を両方とも一体的に内蔵するタイプのものである。空調ケース１１はポリプロピレンのような、ある程度の弾性を有し、強度的にも優れた樹脂の成形品からなる。空調ケース１１は具体的には複数の分割ケースからなり、この複数の分割ケースを金属バネクリップ、ネジ等の締結手段により一体に結合するようになっている。
【００３４】
空調ユニット１０部は、計器盤内側の車両幅方向の略中央部において、車両の前後、上下方向に対して、図１、図２の矢印に示す形態で配置されている。空調ケース１１内の、最も車両前方側の部位には空気入口空間１４が形成されている。この空気入口空間１４には、前述の送風機ユニットから送風される空調空気が流入する。
【００３５】
空調ケース１１内において空気入口空間１４直後の部位に蒸発器１２が配置されている。この蒸発器１２は車両前後方向には薄型の形態で空調ケース１１内通路を横断するように上下方向に配置されている。従って、空気入口空間１４からの送風空気が蒸発器１２を通過して車両後方側へ流れる。この蒸発器１２は周知のごとく冷凍サイクルの冷媒の蒸発潜熱を空調空気から吸熱して、空調空気を冷却する冷房用熱交換器である。空調ケース１１の底面部には蒸発器１２で発生した凝縮水を排出するドレンパイプ１１ａが備えられている。
【００３６】
そして、蒸発器１２の空気流れ下流側（車両後方側）に、所定の間隔を開けてヒータコア１３が配置されている。このヒータコア１３は空調ケース１１内の下方側において、車両後方側に傾斜して配置されている。なお、蒸発器１２およびヒータコア１３の車両幅方向の幅寸法は、空調ケース１１の幅寸法と略同等に設計されている。
【００３７】
ヒータコア１３は、蒸発器１２を通過した冷風を再加熱するものであって、その内部に高温の温水（エンジン冷却水）が流れ、この温水を熱源として空気を加熱する温水式暖房用熱交換器である。空調ケース１１内の空気通路において、ヒータコア１３の上方部位には、このヒータコア１３をバイパスして空気（冷風）が流れる冷風通路１５が形成されている。
【００３８】
また、ヒータコア１３と蒸発器１２との間の部位には平板状のエアミックスドア１６が配置されている。このエアミックスドア１６は、ヒータコア１３で加熱される温風と、冷風通路１５を通ってヒータコア１３をバイパスする冷風との風量割合を調整する。
【００３９】
エアミックスドア１６は車両幅方向に水平に配置された回転軸１７と一体に結合されており、この回転軸１７を中心として車両上下方向に回転可能になっている。このエアミックスドア１６は上記風量割合の調整により車室内前席側への吹出空気温度を調整する前席側温度調整手段を構成する。
【００４０】
回転軸１７は、空調ケース１１に回転自在に支持され、かつ回転軸１７の一端部は空調ケース１１の外部に突出して、図示しないリンク機構を介して、サーボモータ等を用いたアクチュエータ機構または手動操作機構に連結され、このアクチュエータ機構または手動操作機構によりエアミックスドア１６の回転位置を調整するようになっている。
【００４１】
そして、空調ケース１１において、ヒータコア１３の空気下流側（車両後方側の部位）には、ヒータコア１３の直後から上方に向かう温風通路１８が形成されている。温風通路１８の下流側（上方側）はヒータコア１３の上方部において冷風通路１５の下流側と合流し、冷風と温風の混合を行う空気混合部１９を形成している。
【００４２】
一方、空調ケース１１の上面壁部において空気混合部１９の直ぐ上方部位、換言すると、空調ケース１１のうち上面壁部の車両後方側の部位に、フェイス開口部２０が開口している。このフェイス開口部２０は図示しないフェイスダクトを介して、計器盤上方側に配置されているフェイス吹出口に接続され、このフェイス吹出口から空調風（冷風）を前席乗員の上半身側に向けて吹き出す。
【００４３】
空調ケース１１内において、フェイス開口部２０の下側部にフェイスドア２１を配置してフェイス開口部２０を開閉するようになっている。このフェイスドア２１は車両幅方向に延びる細長い長方形の板状ドアであり、空調ケース１１の上面壁部の車両後方側端部に配置された回転軸２２に連結され、この回転軸２２を中心として回転可能になっている。
【００４４】
また、空調ケース１１の上面壁部においてフェイス開口部２０より車両前方側の部位にデフロスタ開口部２３が開口している。このデフロスタ開口部２３は空気混合部１９から温度制御された空調風が流入するものであって、図示しないデフロスタダクトを介してデフロスタ吹出口に接続され、このデフロスタ吹出口から、車両前面窓ガラスの内面に向けて空調風を吹き出す。
【００４５】
空調ケース１１内においてデフロスタ開口部２３の下側部にデフロスタドア２４を配置して、デフロスタ開口部２３を開閉するようになっている。デフロスタドア２４はフェイスドア２１と同様に車両幅方向に延びる細長い長方形の板状ドアであり、このデフロスタドア２４は空調ケース１１の内側にてデフロスタ開口部２３の車両前方側の部位に配置された回転軸２５に連結され、この回転軸２５を中心として回転可能になっている。
【００４６】
次に、空調ケース１１において車両幅方向の左右両側の側面壁部にはフット開口部２６が開口している。このフット開口部２６は図１に示すようにヒータコア１３の上方部に位置する空気混合部１９の領域と重合する部位に配置されている。また、フット開口部２６は略扇形に形成され、略扇形の要の位置を下方側に配置しているので、フット開口部２６の開口面積は下方より上方側で拡大するようになっている。
【００４７】
そして、この略扇形のフット開口部２６を開閉するために略扇形のフットドア２７が回転軸２８により回転可能に設けてある。この回転軸２８はエアミックスドア１６の回転軸１７の直ぐ車両後方側部位に隣接配置され、フット開口部２６の略扇形の要の位置に配置されている。また、回転軸２８は車両幅方向に延びて両端部が空調ケース１１に回転可能に支持される。
【００４８】
ここで、略扇形のフットドア２７は回転軸２８の両端部近傍にて空調ケース１１の左右の両側面壁部の内面に沿うように配置され、左右の両側面壁部の内面に沿って移動することにより、フット開口部２６を開閉するようになっている。略扇形のフットドア２７と回転軸２８は樹脂にて一体成形できる。フット開口部２６は空調ケース１１の車両幅方向の左右の両側面壁部にて車室内に開口して、前席乗員の足元部へ空調風を吹き出すものである。
【００４９】
また、フェイスドア２１とデフロスタドア２４とフットドア２７は、前席側の吹出モード切替用のドア手段であって、各ドア２１、２４、２７の回転軸２２、２５、２８は、いずれも車両幅方向に延びるように配置されている。そして、空調ケース１１の外表面にて各回転軸２２、２５、２８は図示しないリンク機構を介して、サーボモータ等からなる吹出モード切替用のアクチュエータ機構もしくは手動操作機構に連結されて、このアクチュエータ機構もしくは手動操作機構により連動操作されるようになっている。
【００５０】
次に、後席側への吹出空気温度の調整および後席側吹出モードの切替を行う後席側制御機構３０について説明する。後席側制御機構３０は空調ユニット１０のうち、車両後方側の下部に配置された略円筒状の補助ケース３１を備えている。この補助ケース３１は空調ケース１１に樹脂にて一体成形されている。補助ケース３１の内部に後席エアミックス用ドア手段を構成する第１膜状部材３２（図３、４）と、後席吹出モード用ドア手段を構成する第２膜状部材３３（図３、４）を配置している。
【００５１】
ここで、第１、第２膜状部材３２、３３は下記するようにともにループ状（環状）に形成され、後席エアミックス用の第１膜状部材３２が内側に位置し、後席吹出モード用の第２膜状部材３３が第１膜状部材３２の外側に位置するようにして、両膜状部材３２、３３は補助ケース３１の円筒状内部空間の径方向に積層配置される。
【００５２】
両膜状部材３２、３３の具体的材質としては可撓性を有し、かつ、摩擦抵抗が小さい樹脂材料であるＰＥＴ（ポリエチレンテレフタレート）フィルム、あるいはＰＰＳ（ポリフェニレンサルファイド）フィルム等が好適であり、その他に、適度の剛性を持ったエラストマフィルム等を使用してもよい。
【００５３】
第１膜状部材３２の展開形状は図５（ｂ）に示すように所定の幅寸法Ｗ１により細長く延びる形状であり、その幅方向の左右両端部付近にはギヤ穴３２１が形成してある。このギヤ穴３２１は第１膜状部材３２の長手方向の全域にわたって形成してある。また、第１膜状部材３２の長手方向の中央部付近に後席側吹出空気が通過する開口部３２２が開口している。そして、この開口部３２２の前後両側に閉口部３２３、３２４が形成してある。
【００５４】
更に、第１膜状部材３２において、前後両側の閉口部３２３、３２４の左右両端部から連結部３２５、３２６が長手方向の外側へ延びるように形成してある。この連結部３２５、３２６の先端部（斜線部）３２５ａ、３２６ａを重合して熱溶着（ホットメルト）、両面テープ、縫製等の手段にて一体に接合することにより、第１膜状部材３２の全体形状を図５（ａ）に示すようにループ状（環状）に形成してある。なお、図５（ａ）の２点鎖線部は連結部３２５、３２６を示す。
【００５５】
第１膜状部材３２によるエアミックスドア機能は後述するように開口部３２２とその前後両側の閉口部３２３、３２４とにより発揮するようになっている。連結部３２５、３２６はギヤ穴３２１を形成するために必要な狭い幅寸法にて延びる短冊状の形状であり、この短冊状の左右の連結部３２５の間、および短冊状の左右の連結部３２６の間にそれぞれ切り欠き部３２７、３２８を形成して、第２膜状部材３３の開口部３３２（図６参照）を通過する後席側吹出空気の流れを妨げないようにしてある。
【００５６】
後席吹出モード用の第２膜状部材３３も第１膜状部材３２に準じた構成になっており、第２膜状部材３３の展開形状は図６（ｂ）に示すように所定の幅寸法Ｗ２により細長く延びる形状であり、その幅方向の左右両端部付近にはギヤ穴３３１が形成してある。このギヤ穴３３１は第２膜状部材３３の長手方向の全域にわたって形成してある。
【００５７】
また、第２膜状部材３３の長手方向の中央部付近に後席側吹出空気が通過する開口部３３２が開口している。そして、この開口部３３２の前後両側に閉口部３３３、３３４が形成してある。ここで、前後両側の閉口部３３３、３３４のうち、一方の閉口部３３４の第２膜状部材長手方向の寸法Ｌ１を他方の閉口部３３４の第２膜状部材長手方向の寸法Ｌ２より大きくして、後述の後席シャットモード（後席全閉モード）を設定できるようにしてある。
【００５８】
なお、図６（ｂ）において、Ｗ３は左右の両ギヤ穴３３１間の間隔であり、このギヤ穴間の間隔Ｗ３は第１膜状部材３２の幅寸法Ｗ１より大きくしてある。すなわち、Ｗ３＞Ｗ１の関係となるように、両膜状部材３２、３３の幅寸法を設計している。
【００５９】
更に、第２膜状部材３３において、前後両側の閉口部３３３、３３４の左右両端部から連結部３３５、３３６が長手方向の外側へ延びるように形成してある。この連結部３３５、３３６の先端部（斜線部）３３５ａ、３３６ａを重合して前述の熱溶着等の手段にて一体に接合することにより、第２膜状部材３３の全体形状を図６（ａ）に示すようにループ状（環状）に形成してある。なお、図６（ａ）の２点鎖線部は連結部３３５、３３６を示す。

第２膜状部材３３による吹出モードドア機能は後述するように開口部３３２とその前後両側の閉口部３３３、３３４とにより発揮するようになっている。連結部３３５、３３６はギヤ穴３３１を形成するために必要な狭い幅寸法にて延びる短冊状の形状であり、この短冊状の左右の連結部３３５の間、および短冊状の左右の連結部３３６の間にそれぞれ切り欠き部３３７、３３８を形成して、第１膜状部材３２の開口部３２２を通過する冷風および温風の流れを妨げないようにしてある。
【００６１】
次に、後席側制御機構３０側の全体構成を図３、図４により具体的に説明すると、ヒータコア１３の下部と空調ケース１１の底面部との間に後席冷風通路３４が形成してあり、この後席冷風通路３４と前席側の温風通路１８との間は空調ケース１１と一体の仕切り壁３５により仕切られている。略円筒状の補助ケース３１において車両前方側の下方寄りの部位には後席冷風通路３４と連通する後席冷風入口３６が開口している。後席冷風通路３４の冷風は後席冷風入口３６から第１膜状部材３２の開口部３２２を通過して補助ケース３１の内側空間へ流入する。
【００６２】
また、略円筒状の補助ケース３１において車両前方側の上方寄りの部位にはヒータコア１３の空気吹出部の下部に連通する後席温風入口３７が開口している。ヒータコア１３を通過した温風は後席温風入口３７から第１膜状部材３２の開口部３２２を通過して補助ケース３１の内側空間へ流入する。
【００６３】
また、略円筒状の補助ケース３１において車両後方側の下方寄りの部位には後席側フェイス開口部３８が開口し、補助ケース３１の車両後方側の上方寄りの部位には後席側フット開口部３９が開口している。補助ケース３１の内側空間の空気が第２膜状部材３３の開口部３３２を通過して後席側フェイス開口部３８または後席側フット開口部３９へ流れる。
【００６４】
後席側フェイス開口部３８には図示しない後席側フェイスダクトが接続され、この後席側フェイスダクト先端部の後席側フェイス吹出口から空調風を後席乗員の上半身側へ吹き出すようになっている。また、後席側フット開口部３９には図示しない後席側フットダクトが接続され、この後席側フットダクト先端部の後席側フット吹出口から空調風を後席乗員の足元側へ吹き出すようになっている。
【００６５】
上記のように計４個の開口部３６〜３９が開口する略円筒状の補助ケース３１の内部空間には、補助ケース３１の内周面に沿って第１、第２膜状部材３２、３３の移動をガイドする複数のガイド壁４０が空調ケース１１に一体成形されている。
【００６６】
補助ケース３１の内周面とガイド壁４０の外周面との間には所定の間隔が開けてあり、この所定間隔の間にループ状の第１、第２膜状部材３２、３３が略円筒状の円周方向（回転方向）に移動可能に組み込んである。すなわち、第１膜状部材３２が内側に位置し、第２膜状部材３３が第１膜状部材３２の外側に位置するようにして２重のループ状に組み込んである。このループ状の第１、第２膜状部材３２、３３は、略円筒状の補助ケース３１の周方向に開口している４個の開口部３６〜３９に沿って摺動するスライドドアを構成する。
【００６７】
ここで、第１膜状部材３２は図３、図５（ａ）に示すように開口部３２２、閉口部３２３、３２４が車両前方側に位置し、連結部３２５、３２６部分が車両後方側に位置するようになっている。
【００６８】
図３、図５（ａ）は第１膜状部材３２の開口部３２２により後席温風入口３７を全開し、閉口部３２４により後席冷風入口３６を全閉する最大暖房位置を示している。図３、図５（ａ）の回転位置から第１膜状部材３２を反時計方向へ所定の作動角例えば９０°程度回転すると、第１膜状部材３２の開口部３２２により後席冷風入口３６を全開し、閉口部３２３により後席温風入口３７を全閉する最大冷房位置に到達する。
【００６９】
また、第２膜状部材３３においては、図３、図６（ａ）に示すように開口部３３２、閉口部３３３、３３４が車両後方側に位置し、連結部３３５、３３６部分が車両前方側に位置するようになっている。図１、図３、図６（ａ）は第２膜状部材３３の開口部３３２により後席側フット開口部３９を全開し、閉口部３３４により後席側フェイス開口部３８を全閉する後席フットモードの状態を示している。
【００７０】
図３、図６（ａ）の回転位置から第２膜状部材３３を時計方向へ所定の作動角回転させると、第２膜状部材３３の開口部３３２により後席側フェイス開口部３８と後席側フット開口部３９を同時に開口する後席バイレベルモードを設定できる。この後席バイレベルモードの回転位置から第２膜状部材３３をさらに時計方向へ所定の作動角回転させると、第２膜状部材３３の開口部３３２により後席側フェイス開口部３８を全開し、閉口部３３３により後席側フット開口部３９を全閉する後席フェイスモードを設定できる。なお、図２は後席フェイスモードの状態を示している。
【００７１】
また、図３、図６（ａ）に示す後席フットモードの回転位置から第２膜状部材３３を反時計方向へ所定の作動角回転させると、第２膜状部材３３の閉口部３３４により後席側フェイス開口部３８と後席側フット開口部３９を同時に全閉する後席シャットモードを設定できる。このように第２膜状部材３３は後席の吹出モードとして４つのモードを切替設定するため、第２膜状部材３３の合計作動角は第１膜状部材３２の作動角（例えば９０°程度）よりも大きくしてあり、例えば、１２０°程度である。
【００７２】
なお、前席側の吹出モードがデフロスタモードであるときに、後席シャットモードを設定すると、後席側への空気吹出を遮断して空調空気の全量を窓ガラスの曇り止めのために吹き出すことができ、窓ガラスの防曇性能を向上でき、窓ガラスの曇りを速やかに除去できる。
【００７３】
略円筒状の補助ケース３１の円周方向において後席温風入口３７と後席側フット開口部３９との間、および後席冷風入口３６と後席側フェイス開口部３８との間には、それぞれ車両前後方向に延びる比較的大きな円周壁部４１、４２が形成してある。この円周壁部４１、４２によってそれぞれ矢印の範囲で示す膜状部材収納部４１ａ、４２ａを構成する。
【００７４】
ここで、膜状部材収納部４１ａ、４２ａは内外２重のループ状に組み込まれる両膜状部材３２、３３に共通使用されるものであって、上側の膜状部材収納部４１ａは両膜状部材３２、３３の一方の閉口部３２３、３３３の収納のために使用される領域であり、そして、下側の膜状部材収納部４２ａは両膜状部材３２、３３の他方の閉口部３２４、３３４の収納のために使用される領域である。
【００７５】
一方、略円筒状の補助ケース３１の内部空間において、上側の膜状部材収納部４１ａの下方側で、第１、第２膜状部材３２、３３よりも内周側の部位に第１膜状部材３２の駆動軸４３を配置し、また、略円筒状の補助ケース３１の内部空間において、下側の膜状部材収納部４２ａの上方側で、第１、第２膜状部材３２、３３よりも内周側の部位に第２膜状部材３３の駆動軸４４を配置している。
【００７６】
この駆動軸４３、４４の両端部は、空調ケース１１の左右の側面部に設けられた軸受穴４５、４６（図４）により回転自在に支持されている。この駆動軸４３、４４にはそれぞれ外周上に多数の歯を有する平歯車状の駆動ギヤ４７、４８が一体に設けてある。
【００７７】
駆動軸４３の駆動ギヤ４７は第１膜状部材３２の幅方向の左右両側のギヤ穴３２１の間隔に対応する間隔で設けてあり、この駆動ギヤ４７の歯をギヤ穴３２１とかみ合わせる。従って、駆動軸４３と一体に駆動ギヤ４７が回転することにより第１膜状部材３２が回転変位する。
【００７８】
他方の駆動軸４４の駆動ギヤ４８は、第２膜状部材３３の幅方向の左右両側のギヤ穴３３１の間隔に対応する間隔で設けてあり、この駆動ギヤ４８の歯をギヤ穴３３１とかみ合わせる。従って、駆動軸４４と一体に駆動ギヤ４８が回転することにより第２膜状部材３３が回転変位する。
【００７９】
ここで、第２膜状部材３３のギヤ穴３３１の間隔Ｗ３（図６（ｂ））が第１膜状部材３２の幅寸法Ｗ１より大きいので、左右の駆動ギヤ４８が第１膜状部材３２の幅寸法Ｗ１の左右外側に位置することになる。そのため、第２膜状部材３３が第１膜状部材３２の外周側に積層するように配置されていても、左右の駆動ギヤ４８が第１膜状部材３２と干渉することはない。
【００８０】
なお、駆動軸４３と駆動ギヤ４７とにより第１膜状部材３２の駆動機構を構成し、駆動軸４４と駆動ギヤ４８とにより第２膜状部材３３の駆動機構を構成している。駆動軸４３の一端部は図示しないリンク機構等を介して後席温度調整操作機構に連結され、この後席温度調整操作機構により駆動軸４３の作動角、最終的には後席エアミックス用第１膜状部材３２の作動角が調整される。
【００８１】
同様に、駆動軸４４の一端部も図示しないリンク機構等を介して後席吹出モード操作機構に連結され、この後席吹出モード操作機構により駆動軸４４の作動角、最終的には後席吹出モード切替用第２膜状部材３３の作動角が調整される。
【００８２】
後席温度調整操作機構および後席吹出モード操作機構は通常サーボモータを用いたアクチュエータ機構により構成されが、直接手動操作される手動操作機構により後席温度調整操作機構および後席吹出モード操作機構を構成してもよい。
【００８３】
また、本実施形態では第１、第２膜状部材３２、３３のループ形状を完全な円形状とせずに、長円状の形状にしている。すなわち、第１、第２膜状部材３２、３３のループ形状の径寸法を、２つの駆動軸４３、４４の積層方向（上下方向）の径寸法よりも２つの駆動軸４３、４４の積層方向と直交する方向（車両前後方向）の径寸法を大きくして、第１、第２膜状部材３２、３３のループ形状を車両前後方向が長軸方向となる長円状に形成している。これにより、膜状部材収納部４１ａ、４２ａの領域を拡大するようにしている。
【００８４】
なお、図１、２に示すように、蒸発器１２の上方の直後の部位に、冷風バイパス通路５０、および冷風バイパス通路５０を開閉する冷風バイパスドア５１が設けてある。この冷風バイパスドア５１は、エアミックスドア１６が最大冷房位置（図２の位置）にあるとき等に、これに連動して冷風バイパス通路５０を全開するようになっている。
【００８５】
次に、上記構成において本実施形態の作動を説明する。前席側吹出モード切替用のドア手段をなすフェイスドア２１、デフロスタドア２４およびフットドア２７の操作位置を選択することにより、周知のフェイスモード、バイレベルモード、フットモード、フットデフロスタモード、およびデフロスタモードの各種の吹出モードを車室内前席側の空調のために設定できる。
【００８６】
そして、前席側温度調整手段をなすエアミックスドア１６の開度位置を調整して、冷風通路１５を通過する冷風とヒータコア１３への通風路を通過する温風との風量割合を調整することにより車室内の前席側への吹出空気温度を所望温度に調整できる。
【００８７】
次に、後席側制御機構３０の作動を説明すると、図示しない後席温度調整操作機構により駆動軸４３の作動角を調整して、後席エアミックス用第１膜状部材３２の作動角を調整することにより、第１膜状部材３２の開口部３２２と後席冷風入口３６および後席温風入口３７との連通開口面積が変化する。これにより、後席冷風入口３６からの冷風流入量と後席温風入口３７からの温風流入量との割合を変化させることができ、車室内の後席側への吹出空気温度を所望温度に調整できる。
【００８８】
また、図示しない後席吹出モード操作機構により駆動軸４４の作動角を調整して、後席吹出モード用第２膜状部材３３の作動角を調整することにより、第２膜状部材３３の開口部３３２と後席側フェイス開口部３８および後席側フット開口部３９との連通開口面積が変化する。これにより、前述した後席フェイスモード、後席バイレベルモード、後席フットモードおよび後席シャットモードの合計４つの吹出モードを切替設定できる。
【００８９】
なお、図１、図３は前席側および後席側の吹出モードがともにフットモードであり、そして、前席側温度調整手段をなすエアミックスドア１６および前席側温度調整手段をなす第１膜状部材３２がともに最大暖房位置にある状態を示し、前席側においてはヒータコア１３で加熱された温風が前席側フット開口部２６から前席乗員の足元部へ吹き出す。
【００９０】
また、後席側制御機構３０においては、ヒータコア１３で加熱された温風が後席温風入口３７から第１膜状部材３２の開口部３２２を通過して第１膜状部材３２の内側へ流入する。この温風は、更に、第２膜状部材３３の開口部３３２を通過して後席側フット開口部３９へ流れる。この後席側フット開口部３９から温風は図示しない後席フット接続ダクトを経て後席乗員の足元部へ吹き出す。
【００９１】
図２は前席側および後席側の吹出モードがともにフェイスモードであり、そして、前席側温度調整手段をなすエアミックスドア１６および前席側温度調整手段をなす第１膜状部材３２がともに最大冷房位置にある状態を示している。前席側においては、蒸発器１２で冷却された冷風が冷風通路１５および冷風バイパス通路５０を通過して前席側フェイス開口部２０へ流れ、この前席側フェイス開口部２０から冷風が図示しない前席側フェイスダクトを経て前席乗員の上半身側へ吹き出す。
【００９２】
また、後席側制御機構３０においては、蒸発器１２で冷却された冷風が後席側冷風通路３４から第１膜状部材３２の開口部３２２を通過して第１膜状部材３２の内側へ流入する。この冷風は、更に、第２膜状部材３３の開口部３３２を通過して後席側フェイス開口部３８へ流れる。この後席側フェイス開口部３８から冷風は図示しない後席フェイス接続ダクトを経て後席乗員の上半身側へ吹き出す。
【００９３】
次に、本実施形態による作用効果を説明する。
【００９４】
▲１▼後席側制御機構３０において、周方向に配置された複数の開口部３６〜３９を有する略円筒状のケース部材３１内に、可撓性を有するループ状の第１、第２膜状部材３２、３３を径方向に積層配置し、ループ状の第１、第２膜状部材３２、３３が開口部３６〜３９に沿って回転変位することにより複数の開口部３６〜３９を開閉するようになっているから、ループ状の第１、第２膜状部材３２、３３の回転変位により複数の開口部３６〜３９を開閉することができる。
【００９５】
これにより、後席温度調整用のエアミックスドア機能及び後席吹出モード機能を略円筒状のケース部材３１内にコンパクトに構成でき、後席側制御機構３０の体格を小型化できる。
【００９６】
更に、第１、第２膜状部材３２、３３がともにループ状であるから、両膜状部材３２、３３に対して駆動ギヤ４７、４８機構の引っ張り力を常に作用させることができる。従って、両膜状部材３２、３３を比較的小さな駆動力にて確実に回転変位させることができる。
【００９７】
▲２▼第１、第２膜状部材３２、３３の閉口部３２３、３２４、３３３、３３４を、共通の収納部４１ａ、４２ａの内側領域に収納しているから、第１、第２膜状部材３２の閉口部３２３、３２４、３３３、３３４をそれぞれ独立した収納部に収納する場合に比して後席側制御機構３０の体格を大幅に小型化できる。
【００９８】
▲３▼ループ状の第１、第２膜状部材３２、３３をそれぞれ独立に駆動する複数の駆動機構、すなわち、駆動軸４３、４４、駆動ギヤ４７、４８を、ループ状の第１、第２膜状部材３２、３３の内側領域に配置しているから、駆動機構をも含めて後席側制御機構３０の体格を更に小型化できる。
【００９９】
▲４▼ループ状の第１、第２膜状部材３２、３３のうち、略円筒状のケース部材３１の径方向の外側に配置される第２膜状部材３３の幅寸法を、径方向の内側に配置される第１膜状部材３２の幅寸法より大きくし、径方向の外側に配置される第２膜状部材３３を回転変位させる駆動ギヤ４８を、径方向の内側に配置される第１膜状部材３２の幅寸法の外側に配置し、第１膜状部材３２を回転変位させる駆動ギヤ４７を第１膜状部材３２の幅寸法の範囲内に配置している。
【０１００】
これにより、ループ状の第１、第２膜状部材３２、３３をその内側領域に配置した複数の駆動機構４３、４４、４７、４８にてギヤ駆動する場合に、径方向の外側に配置される第２膜状部材３３を、内側に配置される第１膜状部材３２との干渉を起こすことなく、円滑にギヤ駆動することができる。
【０１０１】
▲５▼エアミックスドアを構成する第１膜状部材３２を筒状の径方向の内側に配置し、吹出モードドアを構成する第２膜状部材３３を筒状の径方向の外側に配置しているため、第１、第２膜状部材３２、３３の閉口部３２３、３２４、３３３、３３４によるシール機能を良好に発揮できる。
【０１０２】
すなわち、車室内へ向かって流れる空気流れに対してエアミックスドアを構成する第１膜状部材３２は上流側に位置し、吹出モードドアを構成する第２膜状部材３３は下流側に位置する。従って、第１膜状部材３２を空気流れの風圧により筒状の径内方側へ変位させ、第１膜状部材３２の内側に位置しているガイド壁４０に第１膜状部材３２の閉口部３２３、３２４を風圧により圧着することができる。従って、第１膜状部材３２の閉口部３２３、３２４により冷風入口３６と温風入口３７を閉塞する時のシール作用を良好に発揮できる。
【０１０３】
また、吹出モードドアを構成する第２膜状部材３３を空気流れの風圧により筒状の径外方側へ変位させて、ケース部材３１の内壁面に第２膜状部材３３を風圧により圧着することができる。これにより、第２膜状部材３３の閉口部３３３、３３４により複数の吹出開口部３８、３９を閉塞する時のシール作用を良好に発揮できる。
【０１０４】
▲６▼ループ状の第１、第２膜状部材３２、３３を駆動する複数の駆動機構４３、４４、４７、４８を略円筒状のケース部材３１の開口部３６〜３９の部位ではなく、収納部４１ａ、４２ａの部位に対応して配置しているから、複数の駆動機構４３、４４、４７、４８による通風抵抗を減少できる。
【０１０５】
▲７▼複数の駆動機構４３、４４、４７、４８を収納部４１ａ、４２ａの部位に対応して配置することにより、エアミックス用開口部である冷風入口３６と温風入口３７とを互いに接近させることができ、また、吹出開口部３８と３９とを互いに接近させることができる。これにより、共通の収納部４１ａ、４２ａの領域を効果的に拡大できる。
【０１０６】
また、本実施形態では第１、第２膜状部材３２、３３のループ形状を完全な円形状とせずに、長円状の形状にしている。すなわち、第１、第２膜状部材３２、３３のループ形状の径寸法を、２つの駆動軸４３、４４の積層方向（上下方向）の径寸法よりも２つの駆動軸４３、４４の積層方向と直交する方向（車両前後方向）の径寸法を大きくして、第１、第２膜状部材３２、３３のループ形状を車両前後方向が長軸方向となる長円状に形成している。これによって、共通の収納部４１ａ、４２ａの領域を更に拡大できる。
【０１０７】
（他の実施形態）
なお、本発明は上記の一実施形態に限定されることなく種々変形可能である。
【０１０８】
上記の一実施形態では、空気流れを制御する複数のスライドドアとして可撓性を有する膜状部材３２、３３を使用しているが、複数のスライドドアとして可撓性のない剛体のドアを使用してもよい。すなわち、複数のスライドドアが剛体のドアで構成される場合でも、複数のスライドドアの閉口部を収納する共通の収納部を構成することにより、空気通路開閉装置の体格を小型化できる。
【０１０９】
また、スライドドアとして可撓性を有する膜状部材３２、３３にて複数のスライドドアを構成する場合であっても、複数の膜状部材３２、３３を上記の一実施形態のようにループ状とせずに、円弧状、直線状等の形態にしてもよい。このような円弧状、直線状等の膜状部材３２、３３を用いる場合でも、複数の膜状部材３２、３３の移動方向の前後の収納部を共通化することにより、空気通路開閉装置の体格を小型化できる。また、移動方向の前後の収納部をともに共通化せずに、移動方向の前後の片側の収納部のみを共通化するようにしてもよい。
【０１１０】
また、第２膜状部材３３の駆動軸４４、駆動ギヤ４８を第２膜状部材３３の径方向外側に配置しても良い。この場合は駆動ギヤ４８と径方向内側の第１膜状部材３２との干渉が発生しないから、径方向内側の第１膜状部材３２の幅寸法を径方向外側の第２膜状部材３３の幅寸法より小さくする必要が無くなる。従って、両膜状部材３２、３３の幅寸法を同一にしてもよい。
【０１１１】
また、本発明は、車両用空調装置における空気通路の開閉に限らず、種々な用途の空気通路の開閉に対して広く適用できるものである。

BACKGROUND OF THE INVENTION
The present invention relates to an air passage opening and closing device that opens and closes an opening by a sliding door that slides along the opening of an air passage, and a vehicle air conditioner that includes the air passage opening and closing device.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, an air passage opening / closing device that opens and closes an opening by a sliding door that slides along the opening of the air passage is known in a vehicle air conditioner. For example, it is known that an air mix door that adjusts the air volume ratio between cold air and hot air, and a blow-out mode door that opens and closes a plurality of blow-out openings are configured by slide doors.
[0003]
[Problems to be solved by the invention]
However, in the prior art, when the air mix door and the blowout mode door are configured by slide doors, the operating spaces of the plurality of slide doors are independently formed in different parts, so that the physique of the vehicle air conditioner Miniaturization was difficult.
[0004]
In view of the above, an object of the present invention is to reduce the size of an air passage opening and closing device and a vehicle air conditioner that use a plurality of slide doors.
[0005]
Another object of the present invention is to reduce the physique of an air passage opening and closing device and a vehicle air conditioner in which a plurality of slide doors are configured by a flexible film member.
[0010]
[Means for Solving the Problems]
  To achieve the above objective,Claim1In the invention described in the above, the cylindrical case member (31), the plurality of openings (36 to 39) arranged in the circumferential direction of the cylindrical case member (31), and the cylindrical case member (31) A plurality of film-like members (32, 33) that are arranged in a cylindrical radial direction inside and have flexibility,
  A plurality of membrane members (32, 33)pluralA plurality of openings (36 to 39) are opened and closed by being rotationally displaced along the openings (36 to 39).And
  Furthermore, at least one of the plurality of film-like members (32, 33) has a loop shape.Features an air passage opening and closing device.
[0011]
  Thereby, a some opening part (36-39) can be opened and closed by the rotational displacement of a some film-like member (32, 33).
  Here, since the film-like members (32, 33) are flexibly deformed along the sliding path on the case member (31) side, the film-like members (32, 33) are formed along the cylindrical shape of the case member (31). The air passage opening and closing device can be effectively downsized as compared with a rigid sliding door.
  Moreover,Since the plurality of film-like members (32, 33) are arranged in the radial direction in the cylindrical case member (31), the outer shape of the air passage opening and closing device can be combined into an extremely compact cylindrical shape, The physique of the air passage switchgearThanThe size can be effectively reduced.
[0012]
  Claims1The “cylindrical shape” of the case member (31) includes an elliptical cylindrical shape in addition to the cylindrical shape.
[0013]
  further,Claim1Invention described inThenLoop at least one of the plurality of membrane members (32, 33)BecauseA tensile force can always be applied to the loop-like membrane members (32, 33). Therefore,LoopedThe film-like members (32, 33) can be reliably rotated and displaced with a relatively small driving force.
  By the way, when both ends of the film-like member are free ends and a driving force is applied to the middle part of the film-like member to reciprocate in the front-rear direction, the film-like member is moved forward in the direction of travel from the drive force application site. A part will be pushed out by pushing force instead of pulling force. In the extruded portion, the film-like member is very easily bent, and the occurrence of the bend causes a problem that the driving force of the film-like member increases.
  But the claim1According to the plurality of membrane-like members (32, 33)At least one ofSince the film-like members (32, 33) are always rotated and displaced by a pulling force in a loop shape, the film-like members (32, 33) can be reliably displaced by a relatively small driving force.
[0014]
  Claim2In the invention described in claim1The case member (31) is formed with common storage portions (41a, 42a) for storing the closed portions (323, 324, 333, 334) of the plurality of film-like members (32, 33) together. And
[0015]
Thereby, the closed parts of the plurality of membrane members (32, 33) can be stored in the common storage part (41a, 42a), and the physique of the air passage opening / closing device can be further reduced in size.
[0016]
  Claim3In the invention described in claim1 or 2, Provided with a plurality of drive mechanisms (43, 44, 47, 48) for independently driving the plurality of film-like members (32, 33), and the plurality of drive mechanisms (43, 44, 47, 48). It arrange | positions in the inner area | region of the film-like member (32, 33), It is characterized by the above-mentioned.
