【発明の属する技術分野】
本発明は、空気調和機の吸込口に着脱可能に取り付けられるエアフィルタに係わり、より詳細には、エアフィルタを弾性により変形可能な構成にして、吸込グリルを取り外すことなく容易に着脱できるようにしたエアフィルタ取付構造に関する。
【０００２】
【従来の技術】
天井吊下げ型の空気調和機の吸込口に設けられる従来のエアフィルタ取付構造は、例えば実開平４ー１３６４２８号で開示されているように、吸込グリルを取り外してエアフィルタを清掃するようにした構成や、または実開平３ー１１５３２８号で開示されているように、前記吸込グリルを開けて前記エアフィルタを取り付けるようにした構成の事例が知られていた。
【０００３】
しかしながら、前記エアフィルタは、前記吸込グリルを取り外したり開いたりして取り出すようにした構成であるため脱着するのに手間が掛かる上、もし、運転中に前記吸込グリルを取り外したり開いたりした場合には、空気調和機の吸込口から頭髪が吸い込まれるといった事故が発生する恐れがあり危険であった。
【０００４】
このため、特願平９ー２６５４１９に示される吸込グリルを取り外すことなく容易に着脱できるエアフィルタ取付構造を提案している。
図１２は、上述のエアフィルタ取付構造の一例を示す要部拡大断面図、図１３は、上述のエアフィルタ取付構造の他の例を示す要部拡大断面図である。
しかしながら、この場合には、図に示すようにエアフィルタ７とフィルタガイド６の間に隙間ｓを生じる。
【０００５】
一方、この隙間ｓをなくすと、前記エアフィルタ７の挿脱が容易でなくなるおそれがある。
他方、この隙間ｓがあるために、前記エアフィルタ７が図に示すように前記吸込グリル５、または前面カバー４より出っ張りｄを生じるため面一にならず、また、前記エアフィルタ７成形時の反り、返りの発生のため、同様に外観を損ねるおそれがある問題を生じていた。
【０００６】
【発明が解決しようとする課題】
本発明においては、前記問題点に鑑み、エアフィルタを弾性により変形可能な構成にして、吸込グリルを取り外すことなく容易に着脱できるようにするとともに、その際に発生する間隙、エアフィルタの成型時の反り、返りのよる出っ張りを防止した空気調和機のエアフィルタ取付構造を提供することを目的とする。
【０００７】
【課題を解決するための手段】

【０００８】
そして、前記前突起部が、弾性を有する材質により板バネ状に形成され、その上端部が前記フィルタガイド受け部の側壁に設けられているようにする。
【０００９】
また、前記後突起部が、弾性を有する材質により略コ字状に形成され、その両端部が前記フィルタガイド受け部の側壁に設けられているようにする。
【００１０】
さらに、前記後突起部の外側に、前記エアフィルタの挿脱方向に沿って複数の溝部を形成してなるようにする。
【００１１】
そして、前記前突起部、後突起部の上下角隅部に各々テーパ部を形成してなるようにする。
【００１２】
また、前記吸込グリル５のストッパ部と前記エアフィルタ７の間に隙間を設けてなるようにする。
【００１３】
一方、前記前突起部、後突起部を、前記エアフィルタを構成する前記枠体と一体的に形成してなるようにする。
【００１４】
あるいは、前記前突起部、後突起部を、別体で設け、前記エアフィルタの枠体に固着してなるようにする。

前記本体ケーシング２に、前記挿脱口５ｃに連なり、前記フィルタガイド受け部７ａを前記吸込グリル５の内面側に着脱可能に導くフィルタガイド６を設けている。
【００２０】
前記エアフィルタ７を着脱可能に取り付ける際、同エアフィルタ７を、前記挿脱口５ｃから挿入するとともに、弾性変形させながら、前記フィルタガイド６により前記吸込グリル５の内面側に導いて、ねじによりねじ孔に螺着して取り付けるようにした構成となっている。
【００２１】
これによって、前記吸込グリル５を取り外すことなく、各部の厚さ寸法を同一寸法で形成した場合に比べてより容易に、且つ正確に着脱できるようにしてなるので、上記に従来技術で説明したように、前記エアフィルタ７を脱着するのに手間が掛かかったり、運転中に前記吸込グリル５を取り外したり開いたりすることによって、前記吸込口８から頭髪が吸い込まれるといった事故が発生しないよう防止できるようにした構造となる。
【００２２】
また、前記エアフィルタ７を前記挿脱方向に直交して弾性変形させる変形手段が、弾性を有する合成樹脂により帯状に形成された前記フィルタガイド受け部７ａと、同フィルタガイド受け部７ａに下端部が接続されて波形の断面形状に折曲形成された前記フィルタ取付部７ｂとで構成されている。
【００２３】
これによって、前記挿脱口５ｃから前記エアフィルタ７を挿脱する際、同エアフィルタ７を前記挿脱方向に直交して容易に弾性変形させることができるようになるので、前記吸込グリル５を取り外すことなく、同吸込グリル５の内面側に前記エアフィルタ７を容易に着脱できるようにしている。
【００２４】
ここで、本発明によるこの実施例では、前記フィルタガイド受け部７ａの前後に、各々前記前突起部７ａ１、後突起部７ａ２を、前記エアフィルタ７を構成する前記枠体と一体的に形成し、材料費を削減している。
【００２５】

これは、前記エアフィルタ７を後方に付勢するためである。
【００２６】
また、前記後突起部７ａ２が、弾性を有する材質により略コ字状に形成され、その両端部が前記フィルタガイド受け部７ａの側壁に設けられている。
これは、前記エアフィルタ７を前方に押圧するためである。
【００２７】
さらに、前記後突起部７ａ２の外側に、前記エアフィルタ７の挿脱方向に沿って複数の溝部７ａ２ｓを形成している。
これは、厚肉によるヒケを防止し不良率を低下させるために有効である。
【００２８】
また、前記前突起部７ａ１、後突起部７ａ２の上下角隅部に各々テーパ部７ａ１ｔ、７ａ２ｔを形成している。
これは、前記エアフィルタ７の挿入操作性を向上するためである。
【００２９】
そして、前記吸込グリル５のストッパ部と前記エアフィルタ７の間に隙間ｋを設けている。
これは、前記エアフィルタ７の出っ張り防止効果を確実にするためである。
【００３０】
次いで、本発明の実施例の作用について説明する。
前記フィルタガイド受け部７ａの前後に各々前突起部７ａ１、後突起部７ａ２を設けているので、前記エアフィルタ７は、前記吸込グリル５の内面で前記前突起部７ａ１の位置で後方に、前記後突起部７ａ２の位置で前方に押圧される。
【００３１】
そして、前記エアフィルタ７の前記吸込グリル５より下方の部分は、前記前突起部７ａ１を中心に回動し後方に推移する。
【００３２】
このため、前記吸込グリル５を取り外すことなく容易に着脱できるようにするとともに、その際に発生する間隙、前記エアフィルタ７の成型時の反り、返りのよる出っ張りを補正するすることができる。
【００３３】
さらに、前記溝部７ａ２ｓにより厚肉成型時のひけを防止することができる。
また、前記前突起部７ａ１、後突起部７ａ２の上下角隅部に各々テーパ部７ａ１ｔ、７ａ２ｔを形成しているので、挿入が容易となる。
そして、前記吸込グリル５のストッパ部と前記エアフィルタ７の間に隙間ｋを設けているので、前記出っ張りを確実に防止できる。
【００３４】
あるいは、前記前突起部７ａ１、後突起部７ａ２を、別体で設け、前記エアフィルタ７の枠体に固着してなるようにしてもよい。
この場合には、一体的に形成する場合に比較して、前記前突起部７ａ１、後突起部７ａ２自体の成型時の反り、返りを少なくでき、その作用をより強化することができる。
【００３５】
