【発明の属する技術分野】
この発明は、空気調和機及び押し込み固定金具に係り、空気調和機本体からの熱を遮断するための断熱材を、本体へ密着させる押し込み固定金具に関するものである。
【０００２】
【従来の技術】
従来の押し込み固定金具を、エンジンカバーに吸音材を狭圧保持する例により説明する。プッシュナットが、エンジンカバーに設けられたピンに挿入され、さらに圧入することによりプッシュナットのフラット部が、エンジンカバー側に形成された環状突起に着座し、係合歯がピンと締結される。そのとき、吸音材はエンジンカバーとプッシュナットに狭圧され保持される（例えば、特許文献１参照）。
【０００３】
【特許文献１】
特開２０００−４６０２６号公報
【０００４】
【発明が解決しようとする課題】
従来の押し込み固定金具では、プッシュナットのフラット部が環状突起に着座するまで圧入する構成であったため、吸音材の厚みのバラツキや、製品の仕様変更による形状の変化に追従することができなかった。
【０００５】
この発明は、上記のような問題点を解決するためになされたもので、押し込み固定金具で断熱材を本体へ密着させるとともに、断熱材のバラツキや、仕様変更、仕様違いによる形状の相違に対応することができる空気調和機及び押し込み固定金具を提供することを目的とする。
【０００６】
【課題を解決するための手段】
この発明に係る空気調和機は、空気調和機本体と、この本体の何れかの部位に設けられた突起と、この突起に挿入される穴を有し、本体からの熱を遮断するための断熱材と、突起に係合し、断熱材を本体へ密着させる押し込み固定金具とを備え、押し込み固定金具は、突起に係合する穴が一部に切り欠きを有すると共に、突起に係合する穴の中心穴部が突起の径より小さく、突起に挿入方向で係合する場合残存部が弾性変形し、押し込み固定金具の突起に係合する穴は、ほぼ十字状の穴であり、押し込み固定金具の突起に係合する穴の残存部が反挿入側に傾斜し、押し込み固定金具が、弾性を有する材料からなることを特徴とする。
【０００７】
【発明の実施の形態】
以下、この発明の実施の形態を図面に基づいて説明する。
実施の形態１．
図１は実施の形態１を示す図で、空気調和機を示す部分断面側面図である。図において、空気調和機本体１の背面に突起２が形成されている。空気調和機本体１からの熱を遮断するための例えば発砲スチロールからなり、突起２に挿入される穴を有する断熱材３が突起２に挿入される。そして、丸穴を有する押し込み固定金具４を突起２に押し込み断熱材３を空気調和機本体１へ密着させる。断熱材３は発砲スチロールに限定されない。
【０００８】
図１の例は、空気調和機本体１の冷気風路の一部を構成する背面に露付き防止用の断熱材３を密着させるものであるが、この部分に限定されるものではなく、他の部位でもよい。
【０００９】
上述の実施の形態によれば、空気調和機本体１に設けられた突起２と、それに挿入し係合する押し込み固定金具４を用いて断熱材３を密着させ、組み付け効率と信頼性を両立させることができる。
【００１０】
実施の形態２．
図２は実施の形態２を示す図で、空気調和機を示す部分断面側面図である。図に示すように、実施の形態２は、実施の形態１において、押し込み固定金具４がほぼ十字状の穴を有し、該十字状の穴の中心穴部が空気調和機本体１の突起２の径より小さくしたものである。
但し、十字状の穴は一例であり、穴の一部が切り欠きを有し、突起２に圧入した場合、残存部が弾性変形するものであればよい。
【００１１】
次に動作を図２により説明する。空気調和機本体１に形成された突起２に、押し込み固定金具４の十字状の穴を挿入する。押し込み固定金具４のほぼ十字状の穴は、中心穴部が空気調和機本体１の突起２の径より小さいため、十字状の穴の残存部が弾性変形し断熱材３を挟圧するよう圧入される。押し込み固定金具４の十字状の穴の中心穴部は、突起２に係合するため断熱材３は本体１に密着する。
【００１２】
上述の実施の形態によれば、押し込み固定金具４はほぼ十字状の穴を有し、該十字状の穴の中心穴部が本体突起２の径より小さいため、十字状の穴の残存部が弾性変形し、押し込み固定金具４の十字状の穴の中心穴部が、突起２に係合して、断熱材３は狭圧されるため、断熱材３を本体１に密着させる効果がある。
【００１３】
実施の形態３．
図３は実施の形態３を示す図で、空気調和機を示す部分断面側面図である。図に示すように、実施の形態３は、実施の形態２において押し込み固定金具４の十字状の穴の残存部が、反挿入側に傾斜したものである。
【００１４】
次に動作を図３により説明する。空気調和機本体１に構成される突起２に、押し込み固定金具４の十字状の穴を挿入する。押し込み固定金具４の十字状の穴の残存部は、反挿入側に傾斜しているため突起２に容易に圧入され、断熱材３を狭圧する。押し込み固定金具４の十字状の穴の中心穴部は、突起２に係合するため断熱材３は本体１に密着する。
【００１５】
上述の実施の形態によれば、押し込み固定金具４の十字状の穴の残存部が反挿入側に傾斜しているように構成したので、押し込み固定金具４の十字状の穴の中心穴部は、突起２に容易に圧入されて係合し、断熱材３を狭圧し空気調和機本体１に密着させる効果がある。
【００１６】
実施の形態４．
実施の形態４は、実施の形態１〜３において押し込み固定金具４を弾性を有するバネ材により構成したものである。
【００１７】
次に動作を図３により説明する。例えば、上記実施の形態３に適用した場合は、空気調和機本体１に形成された突起２に、押し込み固定金具４の十字状の穴を挿入する。押し込み固定金具４の十字状の穴の残存部は反挿入側に傾斜しており、さらに押し込み固定金具４はバネ材により構成されているため、突起２に容易に圧入され、断熱材３を狭圧する。
実施の形態１、２においても、押し込み固定金具４をバネ材にすることにより、突起２に容易に圧入され、断熱材３を狭圧する。
【００１８】
上述の実施の形態によれば、押し込み固定金具４をバネ材により構成したため、押し込み固定金具４の穴の中心穴部は、突起２により一層容易に圧入されて係合し、断熱材３を狭圧し空気調和機本体１に密着させる効果がある。
【００１９】
実施の形態５．
図４は実施の形態５を示す図で、空気調和機を示す部分断面側面図である。図に示すように、断熱材３の厚さ等の形状が異なる場合でも、実施の形態１〜４に示した押し込み固定金具４を用いることにより、押し込み固定金具４が突起２に容易に圧入され係合し、押し込み固定金具４が断熱材３を空気調和機本体１に狭圧する。
【００２０】
上述の実施の形態によれば、断熱材３の厚さ等の形状が異なる場合でも、実施の形態１〜４に示した押し込み固定金具４を用いることにより、断熱材３を狭圧し空気調和機本体１に密着させる効果がある。
【００２１】
実施の形態６．
図５は実施の形態６を示す図で、空気調和機を示す部分断面側面図である。図に示すように、実施の形態１〜５の構成に加えて、空気調和機本体１の突起２の頂部に、ネジ７により配管押さえ板５を取り付け可能としたものである。空気調和機の据付条件によっては、配管を背面側に這わせて据付ける場合がある。
【００２２】
次に動作を図５により説明する。空気調和機の据付時、空気調和機本体１の背面側に配管６が通る場合、この空気調和機本体１に形成された断熱材取付用の突起２の頂部に、ネジ７により配管押さえ板５を取り付け、断熱材３との間に配管６を挟む。これにより据付時に配管６のまとまりが良く、作業性が向上する。
【００２３】
上述の実施の形態によれば、据付時に空気調和機本体１の背面側に配管６が通る場合、この空気調和機本体１に形成された断熱材取付用の突起２の頂部に、ネジ７により配管押さえ板５を取り付け、断熱材３との間に配管６を挟むことができるようにしたので、空気調和機の据付時に配管６のまとまりが良く、作業性が向上する効果がある。
【００２４】
実施の形態７．
図６は実施の形態７を示す図で、空気調和機を示す部分断面側面図である。図に示すように、実施の形態１〜６において、押し込み固定金具４に複数の穴を設けたものである。図は十字状の穴の例を示しているが、丸穴のものでもよい。
【００２５】
次に動作を図６により説明する。空気調和機本体１に形成された複数の突起２に、押し込み固定金具４に設けられた複数の穴を各々挿入し、断熱材３をより広い面積で狭圧する。押し込み固定金具４の複数のは、空気調和機本体１に形成された複数の突起２の各々と係合するため、断熱材３は空気調和機本体１に密着する。特に断熱材３に柔らかい材質のものを使用した場合に、狭圧する圧力を分散させるので、効果的である。
【００２６】
上述の実施の形態によれば、押し込み固定金具４に、突起２に対応するよう複数の穴を形成したので、断熱材３をより広い面積で狭圧することができ、断熱材３の空気調和機本体１への密着信頼性も向上する効果がある。
【００２７】
【発明の効果】
この発明に係る空気調和機は、空気調和機本体と、この本体の何れかの部位に設けられた突起と、この突起に挿入される穴を有し、本体からの熱を遮断するための断熱材と、突起に係合し、断熱材を本体へ密着させる押し込み固定金具とを備えたことにより、断熱材を本体に密着させる効果がある。
