Description

【０００１】
【発明の属する技術分野】
この発明は、空気清浄フィルタが取り付け可能なエアフィルタに関する。
【０００２】
【従来の技術】
従来、エアフィルタとしては、空気調和機本体内に熱交換器と送風ファンを配置すると共に、上記本体の前面側をパネルで覆い、このパネルと熱交換器との間に着脱自在に取り付けたものがある。上記エアフィルタの裏面には、エアフィルタのネットでは捕捉されない花粉や塵等の空気中の細かい粒子を捕捉する空気清浄フィルタを取り付けている。
【０００３】
【発明が解決しようとする課題】
ところで、上記エアフィルタでは、空気清浄フィルタをエアフィルタの湾曲部分の裏面側に配置している。このため、上記エアフィルタの裏面側に設けられた空気清浄フィルタ用取付枠の位置によって、エアフィルタの剛性が増大して湾曲しにくくなり、特に本体の前面にパネルが固定されて開閉できない空気調和機では、空気清浄フィルタを取り付けたエアフィルタの脱着作業が困難であるという問題がある。
【０００４】
そこで、この発明の目的は、空気清浄フィルタを湾曲部分の裏面側に取り付けても、脱着作業が容易にできるエアフィルタを提供することにある。
【０００５】
【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のエアフィルタは、ネットが張られたエアフィルタ枠に空気清浄フィルタを取り付ける取付枠を備え、空気調和機に湾曲させて装着するエアフィルタにおいて、上記取付枠は、上記エアフィルタ枠の裏面側に設けられ、上記エアフィルタ枠が湾曲しても上記空気清浄フィルタを保持する枠部材を有し、上記エアフィルタ枠の湾曲する部分が曲がりやすいように、上記枠部材の上記エアフィルタ枠が湾曲する辺側に切り欠きを設けたことを特徴としている。
【０００６】
上記請求項１のエアフィルタによれば、上記空気清浄フィルタを取り付ける取付枠がエアフィルタ枠の裏面側に設けられた枠部材を有し、その枠部材によりエアフィルタ枠が湾曲しても空気清浄フィルタを保持すると共に、枠部材のエアフィルタ枠が湾曲する辺側に切り欠きを設けたことによって、空気清浄フィルタをエアフィルタ枠の湾曲する部分の裏面側に取り付けていても、エアフィルタの湾曲する部分の剛性を小さくし、エアフィルタを湾曲しやすくして、エアフィルタの脱着作業を容易に行うことができる。
【０００７】
また、請求項２のエアフィルタは、請求項１のエアフィルタにおいて、上記エアフィルタ枠に張られたネットを上記取付枠よりも風上側に配置したことを特徴としている。
【０００８】
また、請求項３のエアフィルタは、請求項１または２のエアフィルタにおいて、上記切り欠きが設けられた枠部材を上記エアフィルタ枠の外縁よりも内側に設けたことを特徴としている。
【０００９】
また、請求項４のエアフィルタは、請求項３のエアフィルタにおいて、上記切り欠きが設けられた枠部材を上記エアフィルタ枠の内側の縦桟よりも外側に設けたことを特徴としている。
【００１０】
また、請求項５のエアフィルタは、請求項１乃至４のいずれか１つのエアフィルタにおいて、上記切り欠きが設けられた枠部材は、上記エアフィルタ枠の左側の縦桟に立設された左側枠部材と、上記エアフィルタ枠の右側の縦桟に立設された右側枠部材であって、上記取付枠は、上記エアフィルタ枠の上側の横桟に立設された上側枠部材と、上記エアフィルタ枠の下側の横桟に立設された下側枠部材とを有し、上記左側の縦桟および上記右側の縦桟は、上記上側の横桟と上記下側の横桟との間を接続すると共に、上記上側の横桟および上記下側の横桟よりも上記エアフィルタ枠の外縁側に延びておらず、上記左側の縦桟，右側の縦桟以外の縦桟は、上記上側の横桟と上記下側の横桟に交差して接続され、上記エアフィルタ枠の外縁まで延びて接続されていることを特徴としている。
【００１１】
【発明の実施の形態】
以下、この発明のエアフィルタを図示の実施の形態により詳細に説明する。
【００１２】
図１はこの発明の実施の一形態のエアフィルタを用いた空気調和機の断面図であり、１は本体、２は上記本体１内に配置された熱交換器、３は上記本体１内に熱交換器２の後方に配置された送風ファン、４は上記本体１の前面を覆うと共に、前面グリル１１と上面グリル１２とを有するパネルである。そして、上記熱交換器２とパネル４との間にエアフィルタ５を装着している。また、上記本体１の両側面（図１では右側面のみを示す）の内側に、パネル４の下端近傍から上方に向かって延び、上半分が後方に向かって湾曲する下側ガイド１４を形成し、その下側ガイド１４の湾曲部分に沿って所定の間隔をあけて上側ガイド１５を形成している。上記本体１の両側面の下側ガイド１４と上側ガイド１５でエアフィルタ５の両側端を案内する。
【００１３】
上記エアフィルタ５は、図２に示すように、横桟２１，２２と縦桟２３〜２６とを有する略長方形状のエアフィルタ枠２０と、そのエアフィルタ枠２０に張られたネット２７を有すると共に、裏面に空気清浄フィルタ６（図１に示す）用の取付枠３０を有している。上記取付枠３０は、上側の横桟２１の裏面側に横方向に設けられた上側枠部材３１と、下側の横桟２２の裏面側に横方向に設けられた下側枠部材３２と、上記両横桟２１，２２の間の左側の縦桟２５の裏面側に縦方向に設けられた左側枠部材３３と、上記両横桟２１，２２の間の右側の縦桟２６の裏面側に縦方向に設けられた右側枠部材３４とで略長方形状に構成している。なお、上記エアフィルタ枠２０の下側両コーナー部には、係止部２８，２９を設けている。また、図示しないが上記上側枠部材３１と下側枠部材３２には、係止穴を設けて、エアフィルタ５が湾曲しても空気清浄フィルタ６が保持されるように、その係止穴に空気清浄フィルタ６の突起部（図示せず）を係止する。
【００１４】
また、図３は図２に示すエアフィルタ５を図中右側から見た側面図であり、取付枠３０の左側枠部材３３および右側枠部材３４の上端に切り欠き４１を、下端に切り欠き４２を夫々形成すると共に、左側枠部材３３，右側枠部材３４に所定の間隔をあけて切り欠き４３，４３を夫々形成している。
【００１５】
上記構成の空気調和機において、図１に示すように、エアフィルタ５は、本体１の下側の吹出口１ａとパネル４の下端との間に設けられた開口部１３にエアフィルタ５を上端側から挿入すると、本体１の両側面の下側ガイド１４とパネル４によりエアフィルタ５を案内する。上記エアフィルタ５は、挿入途中で下側ガイド１４と上側ガイド１５との案内によって湾曲する。このとき、上記空気清浄フィルタ６の図２に示す取付枠３０の左側枠部材３３，右側枠部材３４に切り欠き４１，４２，４３を形成しているので、左側枠部材３３，右側枠部材３４の剛性が小さく、エアフィルタ５はしなやかに曲がる。そして、上記エアフィルタ５をさらに挿入すると、エアフィルタ５の係止部２８，２９が本体１に係止して、エアフィルタ５の装着が完了する。
【００１６】
このように、上記エアフィルタ５の空気清浄フィルタ用の取付枠３０の左側枠部材３３，右側枠部材３４に切り欠き４１，４２，４３を形成することによって、空気清浄フィルタ６をエアフィルタ５の裏面に取り付けていても、エアフィルタ５がしなやかに曲がり、エアフィルタ５の装着を容易に行うことができる。また、上記エアフィルタ５を取り外すときも、装着時と同様に容易に行うことができる。また、上記横桟２１，２２と縦桟２５，２６の夫々の裏面側すなわち風下側に、空気清浄フィルタ６の取付枠３０を構成する上側枠部材３１，下側枠部材３２，左側枠部材３３および右側枠部材３４を形成しているので、取付枠３０による空気抵抗を低減することができる。
【００１７】
また、上記空気調和機のように、本体の前面にパネルが固定されて開かない空気調和機では、空気清浄フィルタをエアフィルタと別に装着することが困難であっても、この発明のエアフィルタを用いることによって、エアフィルタと共に空気清浄フィルタの脱着が容易にできる。また、パネルを開かなくとも、エアフィルタと空気清浄フィルタを容易に脱着できるので、パネル開閉機構が不要となって、空気調和機のコストを低減することができる。
【００１８】
上記実施の形態では、本体１の前面にパネル４が取り付けられている空気調和機に限らず、前面パネルが本体に開閉自在に取り付けられている空気調和機にこの発明のエアフィルタを適用してもよいのは勿論である。
【００１９】
また、上記実施の形態では、上記取付枠３０の左側枠部材３３，右側枠部材３４に３つの切り欠き４１，４２，４３を夫々設けたが、切り欠きの形状と数はこれに限らず、空気清浄フィルタを取り付けるエアフィルタの湾曲する部分が曲がりやすいように、空気清浄フィルタの取付枠の縦方向の枠部材に適宜な形状と数の切り欠きを設けてよい。
【００２０】
【発明の効果】
以上より明らかなように、この発明のエアフィルタによれば、ネットが張られたエアフィルタ枠に空気清浄フィルタを取り付ける取付枠を備え、空気調和機に湾曲させて装着するエアフィルタにおいて、上記取付枠は、エアフィルタ枠の裏面側に設けられた枠部材を有し、エアフィルタ枠が湾曲しても空気清浄フィルタを枠部材により保持すると共に、上記エアフィルタ枠の湾曲する部分が曲がりやすいように、上記枠部材のエアフィルタ枠が湾曲する辺側に切り欠きを設けたので、空気清浄フィルタをエアフィルタの湾曲する部分の裏面側に取り付けた場合、エアフィルタの湾曲する部分の剛性が小さくなり、エアフィルタがしなやかに曲がって、エアフィルタの脱着作業を容易に行うことができる。
