【発明の属する技術分野】
本発明は自動車用空気調和装置に関する。
【０００２】
【従来の技術】
自動車用空気調和装置は周知のように、ケース内に配設したヒータコアに温水給排用のヒータパイプを接続固定してあって、該ヒータパイプの端部をダッシュパネルに貫通させてエンジンルーム内に突出させ、該ヒータパイプ端をエンジンの冷却系から分岐したヒータチューブを接続するようにしている。
【０００３】
また、ヒータパイプの端部には耐熱性のゴム材からなるシール用のグロメットを装着して、該グロメットをダッシュパネルのヒータパイプが貫通した周縁部に密接させてシールするようにしている。
【０００４】
【発明が解決しようとする課題】
ケース内のヒータコアの配設レイアウトによっては、該ヒータコアに接続したヒータパイプをケース側壁の外側に沿設配置しなければならない場合が考えられる。
【０００５】
ヒータパイプをケース側壁の外側に配管した場合、該ヒータパイプに乗員の脚部が直接触れることがないようにカバーでヒータパイプを覆う必要がある。
【０００６】
また、ヒータパイプがケース外側に配管されるため、前述のグロメットを装着するためにケース側壁にはグロメットの装着およびヒータパイプ端部を支持するための専用のブラケットを固設する必要がある。
【０００７】
このため、部品点数が多くなってその分、部品管理工数，組付作業工数も嵩んでコスト的に不利となってしまう。
【０００８】
そこで、本発明はヒータコアのヒータパイプをケース外に配管した場合でも、部品点数，組付作業工数の増加を可及的に少なく抑制して該ヒータパイプを被覆することができる自動車用空気調和装置を提供するものである。
【０００９】
【課題を解決するための手段】
請求項１の発明にあっては、ヒータコアに接続したヒータパイプを該ヒータコアを配設したケースの側壁の外側に沿設配置した構造であって、前記ヒータパイプの外側を合成樹脂製のパイプカバーで被覆して該パイプカバーをケースの側壁に固定し、該パイプカバーの端部にはブラケット部を一体成形して該ブラケット部にその一側縁からヒータパイプの端部を挿入する切欠部を形成する一方、ケースの側壁に前記ブラケット部の切欠部が開口する側の側縁が係合するブラケット支持壁を突設し、該ブラケット部をその切欠部にヒータパイプの端部を挿入してブラケット支持壁に係合すると共に、ヒータパイプ端に該ヒータパイプが貫通するダッシュパネルの貫通孔縁部に密接するシール用のグロメットを装着し、該グロメットを前記ブラケット部とブラケット支持壁にこれらを覆って嵌着して、該グロメットによりブラケット部をブラケット支持壁に固定したことを特徴としている。
【００１０】
請求項２の発明にあっては、請求項１に記載のケースの側壁には、該ケースの側壁に設けたフット吹出口を覆い、かつ、ケースの側壁との間に該フット吹出口から吹出される温調空気を導出するフットダクトを構成する合成樹脂製のカバー部材が固設され、パイプカバーがこのカバー部材に一体に延設されていることを特徴としている。
【００１１】
【発明の効果】
請求項１に記載の発明によれば、ケース側壁の外側に配管されたヒータパイプは合成樹脂製のパイプカバーで被覆されているから、ヒータパイプが露出して乗員の脚部がヒータパイプに直接触れることがなく、品質感および信頼性を向上することができる。
【００１２】
また、パイプカバーの端部にはブラケット部を一体成形してあり、該ブラケット部の切欠部にヒータパイプの端部を挿入，保持して該ブラケット部の一側縁をケース側壁のブラケット支持壁に衝接係合させ、これらブラケット部とブラケット支持壁を覆ってヒータパイプ端に挿通したグロメットを嵌着して、該グロメットによりブラケット部をブラケット支持壁に固定してあるので、ヒータパイプの端部をしっかりとケース側壁に固定できて、空調ユニットの車載組付作業を容易に行うことができる。
【００１３】
しかも、ブラケット部はパイプカバーに一体成形され、また、ブラケット支持壁はケースに突設してあって、ヒータパイプおよびグロメットを装着するための専用のブラケットが不要になると共に、該グロメット自体でブラケット部のブラケット支持壁への固定を行っていて専用の固定部材が不要となることから、部品点数および組付作業工数等を可及的に少なくできてコスト的に有利に得ることができる。
【００１４】
更に、ケース側にはブラケット部を単純に係合支持するブラケット支持壁を突設するだけであるから、ケースを成形する型構造が複雑となるこがなく、また、成形時の型抜きに支障を来すこともなく成形性を阻害するのを回避することができる。
【００１５】
請求項２に記載の発明によれば、請求項１の発明の効果に加えて、パイプカバーはケース側壁の外側にフットダクトを構成するカバー部材に一体に延設してあるため、部品点数を削減できてより一層コスト的に有利に得ることができる。

【００３１】
また、下側のヒータパイプ２はその一部をカバー部材１０の側面に開口したノズル部１３の１つの下縁に沿って配管してある一方、該ノズル部１３の下縁には図６に示すようにヒータパイプ２の上側を覆うカーリング部１３ａを設けてあり、フットダクト１２を流通する温風がコアンダ゛現象により同図の矢印で示すように該カーリング部１３ａに沿ってノズル部１３から乗員の足元方向に指向して吹出させ易いようにしてある。
【００３２】
以上の実施形態の構造によれば、ケース１の側壁の外側に配管されたヒータパイプ２は合成樹脂製のパイプカバー３で被覆されているから、ヒータパイプ２が車室内に露出して乗員の脚部がヒータパイプ２に直接触れることがなく、品質感および信頼性を向上することができる。
【００３３】
また、パイプカバー３の端部にはブラケット部５を一体成形してあり、該ブラケット部５の切欠部６にヒータパイプ２の端部を挿入，保持して該ブラケット部５の一側縁をケース１の側壁のブラケット支持壁７に衝接係合させ、これらブラケット部５とブラケット支持壁７を覆ってヒータパイプ２の端部に挿通したグロメット８を嵌着して、該グロメット８によりブラケット部５をブラケット支持壁７に固定してあるので、ヒータパイプ２の端部をしっかりとケース１の側壁に固定できて、空調ユニットを車載する際に該ヒータパイプ２の端部をダッシュパネル１５の貫通孔１６に挿入し易く、空調ユニットの車載組付作業を容易に行うことができる。
【００３４】
しかも、ブラケット部５はパイプカバー３に一体成形され、また、ブラケット支持壁７はケース１に突設してあって、ヒータパイプ２およびグロメット８を装着するための専用のブラケットが不要になると共に、該グロメット８自体でブラケット部５のブラケット支持壁７への固定を行っていて専用の固定部材が不要となることから、部品点数および組付作業工数等を可及的に少なくできてコスト的に有利に得ることができる。
【００３５】
更に、ケース１側にはブラケット部５を単純に係合支持するブラケット支持壁７を突設するだけであるから、ケース１を成形する型構造が複雑となることがなく、また、成形時の型抜きに支障を来すこともなく成形性を阻害するのを回避することができる。
