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−及び空気清浄フィルタ−を用いた空調冷凍装置に関するものである。
【０００２】
【従来の技術】
従来のこの種の空調冷凍装置である空気調和機の空気清浄フィルタ−としては、特開平６−２２６０２４号公報に記載された技術がある。
図５は、前記公報に記載された空気清浄フィルタ−を示す斜視図である。
図において、１は、空気清浄フィルタ−であり、また、２は、平板状の単位フィルタ−部材であり、綿埃などを除去する濾過機能及び、折れ曲がる時にヒンジ部として機能する必要から、ポリエチレンやナイロンなどの一般的な樹脂材料によるネット材を使用する。そして、前記単位フィルタ−部材２は後述する枠体片６により濾過体３の両側辺が保持されており、各単位フィルタ−部材２は、濾過体３のみにより形成され、両側辺が枠体片６に保持されないヒンジ部４により折り曲げ自在に連結されている。
【０００３】
枠体片６は、ポリエチレンなどの樹脂によって濾過体３と一体にモ−ルド成形される。そして、枠体片６には、平枠７および取手８が設けられている。枠体片６は、空気調和機１０の嵌合溝１１に嵌合する形状を有し、単位フィルタ−部材２のヒンジ部４、４間の間隔よりも若干短い長さに形成され、左右対称な位置に複数個配置される。そして、嵌合溝１１への挿嵌時に挿嵌しやすいように、また、折り曲げ時に角部分が突き当たらないように枠体片６の両端部に面取り部９を設ける。
平枠７は、空気清浄フィルタ−１の上下に一対設けられて、上下の枠組みを形成し、左右の枠体片６と一体に形成される。取手８は、下側の平枠7に設けられ、空気清浄フィルタ−１の空気調和機１０への着脱時に手を掛けて、空気清浄フィルタ−１を操作する時に用いる。
【０００４】
次に、空気清浄フィルタ−１の着脱方法について以下に説明する。
図５に示すように、空気清浄フィルタ−１の取付け時には、空気調和機１０の空気吸入口１３の下側から空気清浄フィルタ−１を湾曲させながら、先端の平枠７を脱着口１２に差し込む。そして、左右の枠体６を脱着口１２の両端の嵌合溝１１に嵌合する。残りの枠体片６も同様にヒンジ部４を垂直に戻しながら順次空気調和機１０の嵌合溝１１に差し込んでいく。そして、最後の枠体片６がはまり込むまで取手８を操作して押し込んでいく。
【０００５】
また、取手８は、空気調和機１０の脱着口１２の下側に飛び出させて、取り出し時に掴み易いようにしておく。空気清浄フィルタ−１を取り外す場合は、脱着口１２の下側に飛び出た取手８を掴んで引っ張り、空気調和機１０の嵌合溝１１から枠体片６を順次抜き取る。そして、ヒンジ部４を真っ直ぐに戻しながら空気清浄フィルタ−１を空気調和機１０の下側から取り出す。
【０００６】
【発明が解決しようとする課題】
このように従来の空気調和機１０の空気清浄フィルタ−１は、両側辺の枠体片６を嵌合溝１１に挿入することにより、空気清浄フィルタ−１を空気調和機１０に取り付けるものであるが、枠体片６は、挿入方向に相当の長さを有するため、嵌合溝１１が湾曲している場合、着脱がスム−ズにいかないという問題があった。
また、空気清浄フィルタ−１を空気調和機１０に取り付ける際、両側辺の枠体片６を嵌合溝１１に挿入するとともに、濾過体３等を、嵌合溝１１に連続して形成した同じ開口幅の脱着口１２に差し込んでいく。従って、濾過体等の厚さを枠体片６の厚さより大きくすることができない。そこで、濾過体の空気清浄機能のアップのために厚くすることができないという問題が生じた。
【０００７】
本発明は、前記のような問題点を解消するためになされたものであり、湾曲形状をはじめ自由な形状の案内溝にスム−ズに着脱可能な空気清浄フィルタ−を得ることを目的とする。
また、濾過体の厚さを自由に厚くでき、性能アップの可能な空気清浄フィルタ−を得ることを目的とする。
また、空気調和機の運転時に、振動によるビビリ音の発生のない空気清浄フィルタ−を得ることを目的とする。
また、着脱時に、案内溝から外れることのない空気清浄フィルタ−を得ることを目的とする。
また、安価に製造できる空気清浄フィルタ−を得ることを目的とする。
また、これらの空気清浄フィルタ−を取り付けた品質の高い、高性能の空調冷凍装置及び熱交換器の汚染が確実に防止できる空調冷凍装置を得ることを目的とする。
【０００８】
【課題を解決するための手段】
本発明に係る空気清浄フィルタ−は、それぞれ濾過体が装着された複数の単位フィルター枠部材と、これら複数の単位フィルター枠部材を折り曲げ自在に連結するヒンジ部と、前記単位フィルター枠部材の両側面からそれぞれ突出するように設けられ、当該空気清浄フィルターが設置される場所に設けられた案内溝に挿入される案内部とを備え、前記案内溝は、前記案内部が挿入される方向に開口幅が小さくなる楔状であり、前記案内部は、前記案内溝に合せて挿入方向先端から順次断面の大きさが大きくなるように形成されたものである。
【００１０】
また、本発明に係る空気清浄フィルタ−は、前記ボス部の側面に沿って前記ボス部を接続し、前記案内溝に沿って変形可能な弾性体からなるガイド帯を備えたものである。
【００１１】
また、本発明に係る空気清浄フィルターは、複数の単位フィルター枠部材とヒンジ部と案内部とガイド帯が樹脂で一体成形されたものである。
【００１２】
また、本発明に係る空調冷凍装置は、空気吸込口を有するパネル内に配置された熱交換器と、この熱交換器の上流に配置され、それぞれ濾過体が装着された複数の単位フィルター枠部材と、これら複数の単位フィルター枠部材を折り曲げ自在に連結するヒンジ部とから成り、前記空気吸込口から吸込まれ、前記熱交換器に供給されて冷媒と熱交換する空気を濾過する空気清浄フィルターと、この空気清浄フィルターの前記単位フィルター枠部材の両側面からそれぞれ突出するように設けられた案内部と、前記パネルに設けられ、前記案内部が挿入されることで前記空気清浄フィルターを着脱可能に取付ける案内溝とを備え、前記案内溝は、前記案内部が挿入される方向に開口幅が小さくなる楔状であり、前記案内部は、前記案内溝に合せて挿入方向先端から順次断面の大きさが大きくなるように形成されたものである。
【００１３】
また、本発明に係る空調冷凍装置は、空気清浄フィルターが、案内部の側面に沿って、案内部を接続し、弾性変形可能なガイド帯を備えたものである。
【００１４】
また、本発明に係る空調冷凍装置は、熱交換器をパネル内に湾曲して配置するとともに、案内溝を熱交換器の上流で、熱交換器に沿って湾曲状に設け、案内溝に案内部が挿入される空気清浄フィルターが熱交換器を覆うように湾曲して取付けられたものである。
【００１５】
【発明の実施の形態】
実施の形態１．
以下、本発明の実施の形態１を図１、図２により説明する。
図1は、実施の形態１の空気清浄フィルタ−の斜視図である。図２は、空気清浄フィルタ−を取り付けた空気調和機の断面図である。
図において、空調冷凍装置である室内に設置する空気調和機１５のパネル１６の前面に空気吸込口のグリル１７が設けられ、その空気吸込口のグリル１７の背後に送風機１９と送風機１９を覆うように配置された熱交換器１８が内蔵されている。パネル１６の下部には、空気吹出口２０が設けられ、フラップ２１により、開閉および吹出し方向の調整が行われる。
グリル１７と熱交換器１８の間には、熱交換器１８の断面配置に合せて空気清浄フィルタ−１４が取り付けられている。空気清浄フィルタ−１４は、綿埃などを除去する濾過機能を有する平板状の濾過体３を装着する単位フィルタ−枠部材２２が複数個ヒンジ部２３で連結され、折り曲げ自在に連結され、前記熱交換器１８の全面を覆うように取り付けられる。
そして、前記単位フィルタ−枠部材２２は、両側面３５に、それぞれ、少なくとも１個のボス部２５を有し、パネル１６に、このボス部２５と嵌合する湾曲した嵌合溝２６を設け、前記ボス部２５のみが前記嵌合溝２６に、後述の挿入部２８の着脱口４０から挿入され、装着される。
【００１６】
空気清浄フィルタ−１４は、前記の濾過体３を装着し、ヒンジ部２３で連結された複数の単位フィルタ−枠部材２２及び案内部３２であるボス部２５等から構成される。
案内部３２である前記ボス部２５は、単位フィルタ−枠部材２２の両側面３５から対となって、突出した円柱であり、少なくとも各側面から１個で、両側面で対となるように突出している。図２では、1対及び２対の例が示されている。
案内溝である前記嵌合溝２６は、前記の案内部３２であるボス部２５の両側のボス部２５のみを収容するように、両側の開口部を対向させて前記嵌合溝２６の挿入方向に断面コの字状に形成される。
嵌合溝２６の挿入部２８は、図２に示すように、断面コの字状の着脱口４０と、これから下方に延びる支え板部４１とからなる。
但し、形状によっては、挿入部２８は、支え板部４１を設けず、着脱口４０のみとしてもよい。
連結された単位フィルタ−枠部材２２の最後に装着される単位フィルタ−枠部材２２の端部には空気清浄フィルタ−１４の着脱時に操作する取手２７が具備されている。
また、これらの単位フィルタ−部材２２、ヒンジ部２３、ボス部２５及び取手２７は、樹脂によって一体成形され、製作が容易となる。
【００１７】
次に空気清浄フィルタ−１４の着脱方法について説明する。
着脱方法は、空気調和機１５の機種によって異なるが、グリル１７を開くか、取り外すなどして行う。空気清浄フィルタ−１４の取り付け時には、空気調和機１５の空気吸込口１７の下側から空気清浄フィルタ−１４を嵌合溝２６の着脱口４０に差し込み、単位フィルタ−枠部材２２のボス部２５を嵌合溝２６に嵌合させ、差し込んでいく。そして、最後のボス部２５がはまり込むまで取手２７を操作して押し込んでいく。
また、取り外し時は、取手２７を掴み、手前に引き出すことにより、ヒンジ部２３を真っ直ぐに戻しながら嵌合溝２６から単位フィルタ−枠部材２２のボス部２５を順次抜き取る。
なお、装着時に、取手２７を有する端部の単位フィルタ−枠部材２２（取手２７を有する最後の単位フィルタ−枠部材２２）が前記支え板部４１に位置するようにすれば、着脱が容易に行える。
以上のように、単位フィルタ−枠部材２２の側面３５にボス部２５が設けられ、ボス部２５のみがパネル１６に設けた嵌合溝２６と嵌合しているため、濾過体３が平板状であっても、濾過体３の厚みが嵌合溝２６の開口幅に対して薄くてもまた厚くても、嵌合溝２６が熱交換器１８の全面を覆うように湾曲していても、いずれの場合も空気清浄フィルタ−１４は案内溝である嵌合溝２６に対してスム−ズに着脱できる。
また、空気清浄フィルタ−１４を取付ける際、両側のボス部２５のみを案内溝２６に挿入して、連結した単位フィルタ−枠部材２２はフリ−であるので、濾過体３の厚さを案内溝２６の開口幅よりも厚くでき、性能の高い濾過体を使用でき、空気清浄フィルタ−の性能を向上できる。
また、案内溝２６を、熱交換器１８の通風路の上流で、熱交換器１８に沿って湾曲状に設け、案内溝２６に案内部３２を挿入し、空気清浄フィルタ−１４を熱交換器１８を覆うように湾曲して取付けたので、熱交換器１８に供給される空気は、ほとんどが空気清浄フィルタ−１４を通過し、熱交換器１８の汚染防止が確実に行われる。また、湾曲して配置された熱交換器１８に対応して湾曲して案内溝２６を設置しているので、コンパクトな空気調和機１５を得ることができる。
【００１８】
また、図２に示すように、嵌合溝２６の曲率の大きい部分には、単位フィルタ−枠部材２２の挿入方向の長さが比較的小さなものを用いることにより、全体として、空気清浄フィルタ−１４は湾曲への対応が良好となり、熱交換器１８が湾曲していても対応が良好となり、熱交換器１８へ空気清浄フィルタ−１４を通過しない空気の供給を防止するとともに、空気調和機１５のコンパクト化に有効である。
さらに、単位フィルタ−枠部材２２の挿入方向の長さが比較的小さなものを用いる場合は、長さが小さい単位フィルタ−枠部材２２はボス部２５を有しない単位フィルタ−枠部材２２とし、ボス部２５を有する単位フィルタ−枠部材２２と混在させても、連結した単位フィルタ−枠部材２２の着脱は支障がなく、同様な効果の空気清浄フィルタ−１４が得られる。このようにすることにより、空気清浄フィルタ−１４の製作が簡易化できる。
【００１９】
実施の形態２．
実施の形態1では、単位フィルタ−枠部材２２の両側面３５に、少なくとも1個のボス部２５を突出し、このボス部２５のみをパネル１６の湾曲した嵌合溝２６に挿入し、連結した単位フィルタ−枠部材２２を装着したが、本実施の形態では、図３に示すように、単位フィルタ−枠部材２２の両側面３５のボス部２５共に、各側面３５のボス部２５を、弾性体であり、変形可能な平板状のガイド帯２９にて接続し、このボス部２５及びこれらを接続したガイド帯２９からなる案内部３２をパネル１６の湾曲した嵌合溝２６に挿入し、連結した単位フィルタ−枠部材２２を装着するものである。
ガイド帯２９の形成は、単位フィルタ−枠部材２２の各ボス部２５の側面３７に沿って、隣合うボス部２５の側面３７の前面側または背面側を統一して接続する。ここで、前面側とは、嵌合溝２６に挿入する場合、図２の空気吸込口であるグリル１７側になる方であり、背面側とは、その反対側である。
また、図３に示すように、ガイド帯２９とボス部２５の側面３７とが嵌合溝２６内で嵌合溝２６の内壁と摺動するとき、両者は同一の摺動面となるように、ガイド帯２９の厚さ分だけボス部２５の取付け側面３７を削ってガイド帯２９を取付けることにより、より着脱がスム−ズに行われる。
【００２０】
さらに、平板状のガイド帯２９を単位フィルタ−部材２２の前面側に配置すると、空気清浄フィルタ−１４の着脱時に、嵌合溝２６の着脱口４０に干渉することもなく、着脱性が向上する。
また、平板状のガイド帯２９と単位フィルタ−枠部材２２の両側面３５のボス部２５とを樹脂により一体成形にて製造すると安価に製造できる。
また、ガイド帯２９による接続を、連結した単位フィルタ−枠部材２２の側面３５のボス部２５の全体に行わず、部分的に実施してもよい。例えば、図２の空気調和機において、装着時に、案内溝２６の着脱口４０から先端部３８に収容されているボス部２５をガイド帯２９にて接続し、支え板部４１にあるボス部２５はガイド帯２９で接続しないようにしてもよい。得られる効果は同様である。
以上の如く、本実施の形態の案内部３２によると、挿入部２８の着脱口４０から嵌合溝２６に挿入するとき、ボス部２５が嵌合溝２６から外れることが防止でき、よりスム−ズな着脱が可能となる。
【００２１】
実施の形態３．
実施の形態１、２においては、単位フィルタ−枠部材２２の側面３５に設けたボス部２５の突出方向と垂直方向の断面３６のサイズは、同一であるが、図４に示すように、本実施の形態では、ボス部２５の断面３６のサイズを２５ａ、２５ｂ、２５ｃ、２５ｄのように嵌合溝２６の着脱口４０に近いほど大きくすることにより、全体的に案内部３２は楔状に形成されることとなり、また、これに合せて嵌合溝２６も楔状に形成することにより、装着時にボス部２５と嵌合溝２６とは隙間がなく装着することが可能となり、空気清浄フィルタ−１４をパネル１６に確実に保持できるとともに、運転時の空気調和機１５の振動などによるビビリ音等の発生が防止でき、品質の良い空気調和機１５が提供可能となる。
【００２２】
実際の装着においては、図４に示すように、先端部３８の断面を小さく、挿入部２８の着脱口４０の断面を大きくして、即ち、先端部３８にいくほど嵌合溝２６の開口幅を小さくして、先端部３８から着脱口４０まで楔状とした嵌合溝２６を形成し、この楔状の嵌合溝２６に断面サイズの小さなボス部２５ａから挿入し、ボス部２５ａを嵌合溝２６の先端部３８に配置し、以下順次２５ｂ、２５ｃを配置し、また、断面サイズの一番大きなボス部２５ｄを着脱口４０に配置し、さらに、断面サイズが任意の残りのボス部２５を支え板部４１に配置されるように、連結した単位フィルタ−枠部材２２を装着する。即ち、連結した単位フィルタ−枠部材２２のボス部２５のうち、着脱口４０に配置される所定の一端のボス部２５ｄから２５ｃ、２５ｂそして先端部の他端のボス部２５ａまで順次断面の大きさを小さくし、全体として楔状とし、この楔状の案内部３２を、同じく楔状とした案内溝２６に挿入する。
【００２３】
なお、本実施の形態の楔状の案内部３２及び楔状の案内溝２６を、実施の形態２のガイド帯２９及びボス部２５からなる案内部３２に適用してもよいことは当然である。即ち、ボス部２５の断面の大きさを大から小と順次配列し、このボス部２５をガイド帯２９で接続し、楔状の案内部３２を形成し、これに対応した楔状の案内溝２６に挿入する。
【００２４】
本発明は、円形断面のボス部２５にて説明したが、この形状に限らず、楕円または多角形等でもよい。要するに、ボス部２５を嵌合溝２６に挿入するとき、湾曲した嵌合溝２６に対しても単位フィルタ−枠部材２２がスム−ズに着脱可能とするものであればよい。
【００２５】
【発明の効果】
本発明に係る空気清浄フィルターは、それぞれ濾過体が装着された複数の単位フィルター枠部材と、複数の単位フィルター枠部材を折り曲げ自在に連結するヒンジ部と、単位フィルター枠部材の両側面からそれぞれ突出するように設けられ、空気清浄フィルターが設置される場所に設けられた案内溝に挿入される案内部と、を備えたので、ボス部を案内溝に挿入して空気清浄フィルターを取付けることで、湾曲形状をはじめ、自由な形状の案内溝にスム−ズに着脱可能な空気清浄フィルターが得られる。その際、空気清浄フィルターは、案内溝の形状に合せて、ヒンジ部で自在に折り曲がり、案内溝の形状に合せた空気清浄フィルターが得られる。また、案内溝は、案内部が挿入される方向に開口幅が小さくなる楔状であり、案内部は、案内溝に合せて挿入方向先端から順次断面の大きさが大きくなるように形成されたので、挿入する案内溝を楔状とし、楔の方向を合せ、狭い方から広いほうに挿入することにより、案内部が案内溝に密着し、振動などによるビビリ音等が発生しない空気清浄フィルターが得られる。
【００２７】
また、本発明に係る空気清浄フィルタ−は、前記ボス部の側面に沿って前記ボス部を接続し、前記案内溝に沿って変形可能な弾性体からなるガイド帯を備えたので、案内部を案内溝の挿入部に挿入するとき、ボス部が案内溝から外れることがなく、よりスム−ズな装着が可能な空気清浄フィルターが得られる。
【００２８】
また、本発明に係る空気清浄フィルターは、請求項３の空気清浄フィルターにおいて、複数の単位フィルター枠部材とヒンジ部と案内部とガイド帯が樹脂で一体成形されたので、空気清浄フィルターが安価に製作できる。
【００２９】
また、本発明に係る空調冷凍装置は、空気吸込口を有するパネル内に配置された熱交換器と、熱交換器の上流に配置され、それぞれ濾過体が装着された複数の単位フィルター枠部材と、複数の単位フィルター枠部材を折り曲げ自在に連結するヒンジ部とから成り、空気吸込口から吸込まれ、熱交換器に供給されて冷媒と熱交換する空気を濾過する空気清浄フィルターと、空気清浄フィルターの単位フィルター枠部材の両側面からそれぞれ突出するように設けられた案内部と、パネルに設けられ、案内部が挿入されることで空気清浄フィルターを着脱可能に取付ける案内溝と、を備えたので、ボス部を案内溝に挿入して空気清浄フィルタ−を取付けることで、湾曲形状をはじめ、自由な形状の案内溝にスム−ズに着脱可能な空気清浄フィルターを備えた空調冷凍装置を得ることができ、空調冷凍装置の品質が向上する。また、案内溝は、案内部が挿入される方向に開口幅が小さくなる楔状であり、案内部は、案内溝に合せて挿入方向先端から順次断面の大きさが大きくなるように形成されるので、挿入する案内溝を楔状とし、楔の方向を合せ、狭い方から広いほうに挿入することにより、案内部が案内溝に密着し、運転中に振動などによるビビリ音の発生が防止でき、静かな運転音の空調冷凍装置が得られる。
【００３０】
また、本発明に係る空調冷凍装置は、空気清浄フィルターが、案内部の側面に沿って、案内部を接続し、弾性変形可能なガイド帯を備えたので、案内部を案内溝の挿入部に挿入するとき、ボス部が案内溝から外れることがなく、よりスム−ズな空気清浄フィルターの装着が可能な空調冷凍装置が得られる。
【００３１】
また、本発明に係る空調冷凍装置は、熱交換器をパネル内に湾曲して配置するとともに、案内溝を熱交換器の上流で、熱交換器に沿って湾曲状に設け、案内溝に案内部が挿入される空気清浄フィルターが熱交換器を覆うように湾曲して取付けられたので、熱交換器に供給される空気はほとんどが空気清浄フィルターを通過し、熱交換器の汚染防止が確実に行われる。

In the figure, 1 is an air purifying filter, and 2 is a flat unit filter member, which has a filtering function to remove cotton dust and the like, and it needs to function as a hinge part when bent. A net material made of a general resin material such as nylon is used. The unit filter member 2 is held on both sides of the filter body 3 by a frame piece 6 to be described later, each unit filter member 2 is formed only by the filter body 3, and both sides are frame pieces. The hinge part 4 which is not hold | maintained at 6 is connected so that bending is possible.
[0003]
The frame piece 6 is molded integrally with the filter body 3 with a resin such as polyethylene. The frame piece 6 is provided with a flat frame 7 and a handle 8. The frame piece 6 has a shape that fits into the fitting groove 11 of the air conditioner 10, is formed to have a length slightly shorter than the interval between the hinge portions 4, 4 of the unit filter member 2, and is bilaterally symmetric. A plurality are arranged at various positions. And the chamfering part 9 is provided in the both ends of the frame piece 6 so that it may be easy to insert at the time of the insertion to the fitting groove | channel 11, and a corner | angular part does not bump at the time of bending.
A pair of flat frames 7 are provided above and below the air purification filter 1 to form upper and lower frames, and are formed integrally with the left and right frame pieces 6. The handle 8 is provided on the lower flat frame 7 and is used when operating the air purification filter-1 by placing a hand on the air purification filter-1 when it is attached to or detached from the air conditioner 10.
[0004]
Next, the attachment / detachment method of the air purifying filter-1 is demonstrated below.
As shown in FIG. 5, when the air purification filter-1 is attached, the flat frame 7 at the tip is inserted into the attachment / detachment port 12 while curving the air purification filter-1 from the lower side of the air suction port 13 of the air conditioner 10. . Then, the left and right frame bodies 6 are fitted into the fitting grooves 11 at both ends of the attachment / detachment port 12. Similarly, the remaining frame pieces 6 are sequentially inserted into the fitting grooves 11 of the air conditioner 10 while returning the hinge portion 4 to the vertical position. And the handle 8 is operated and pushed in until the last frame piece 6 is fitted.
[0005]
Moreover, the handle 8 is made to jump out to the lower side of the attachment / detachment opening 12 of the air conditioner 10 so that it can be easily grasped when taken out. When removing the air purifying filter 1, the handle 8 protruding to the lower side of the attachment / detachment port 12 is grasped and pulled, and the frame body pieces 6 are sequentially extracted from the fitting grooves 11 of the air conditioner 10.
