Description

【０００１】
【発明の属する技術分野】
本発明は、オフィスやレストラン等で発生する煙草の煙や悪臭を除去する空気清浄機に用いる空気清浄機用放電電極に関する。
【０００２】
【従来の技術】
オフィス、レストラン、遊戯施設等で発生する煙草の煙や悪臭を除去する空気清浄機の一つとして、電気集塵装置を用いたものが、例えば登録実用新案第３０３３８５９号公報に示され、この公報に記載の構成では、浄化運転により電極板の表面が汚れた場合に、空気清浄機等の機器より電極板を取り外して専用の洗剤により洗浄している。
【０００３】
しかし、前記電極板は、比較的重く、機器が例えば室内の天井等に装着されている場合には、その着脱作業がきわめて困難であり、かつ、高価であるという問題点がある。
【０００４】
そこで、本出願人は、コストの低廉化、電極の軽量化、ランニングコストの低減をはかった空気清浄機用放電電極を発明し、特願２０００−２９０２４８で特許出願をしている。
【０００５】
【発明が解決しようとする課題】
前記特許出願の構成では、表面に導電層があるアルミラミネート紙の板体を折曲して貼り合わすようになっているが、Ａ電極・Ｂ電極の切込部を互いに差し込んで格子体に組み立てた場合、切込部を形成するスリットの幅が、例えばトムソン抜き加工に必要な最小幅であっても、貼り合わされた２枚分板体の板厚の約５倍であり、スリットの空隙部分でＡ電極・Ｂ電極に動きが発生する。
【０００６】
これは、集塵電極と放電電極に直流高電圧を印加すると、静電気力により集塵電極と放電電極との間に吸引力が発生し、スリットの空隙部分に動きが発生し、放電特性が不安定となり、集塵効率に影響する。
【０００７】
また、部屋の塵埃を集塵するため、ファンにより空気を循環させて集塵効率を向上させるが、通過する気流によりスリットの空隙部分で電極に動きが発生し、騒音の原因となる、という問題点がある。
【０００８】
本発明は、前記の点に留意し、電極の動きを防止し、集塵効率を向上し、騒音の発生を防ぐ空気清浄機用放電電極を提供することを目的とする。
【０００９】
【課題を解決するための手段】
前記目的を達成するために、本発明の請求項１記載の発明は、格子状に配設された複数の筒状対向電極のほぼ中央部に集塵電極を配設した空気清浄機用放電電極において、

中央部折曲線の他の片側のＢスリットが、中央部折曲線と格子体差込中心線との交点を中心としたＡスリットと点対称の形状であるため、
格子体板体を中央部折曲線で折曲した状態において、ＡスリットとＢスリットが重ならない部分と重なる部分とがあり、重なる部分の幅が、格子体板体の板厚のほぼ２枚分の幅となり、Ａ電極・Ｂ電極の格子体切込部を互いに差し込んで格子体に組み立てた場合、Ａ電極・Ｂ電極間に殆ど隙間がなく、Ａ電極・Ｂ電極に動きが生ぜず、集塵効率が向上し、騒音が発生しない。
【００１１】

【００１４】

【００１５】
つぎに、請求項４記載の発明は、請求項１、２または３記載の発明において、ａ側縁の底部端から中央部折曲線と平行に格子体板体２枚分とほぼ同寸法の底部ラインを形成したものである。
【００１６】

【００１９】
つぎに、請求項６記載の発明は、格子状に配設された複数の筒状対向電極のほぼ中央部に集塵電極を配設した空気清浄機用放電電極において、

前記折曲片の導電層を前記中板の導電層に当接して前記格子体を前記外枠電極に電気的に接続し、
前記外板の上端に突出した押え片を内側に折曲し、前記押え片により挿入された前記折曲片を、前記内板及び前記中板を介して押え、
前記押え片を前記内板に接着して固定し、
かつ、前記内板・中板に前記外枠切込部を形成するスリットを、Ａ’スリット・Ｂ’スリットとし、
前記Ａ’スリットの上部折曲線と直交する両側縁を、ａ’側縁・ｂ’側縁とし、

前記格子体折曲部基部を前記外枠切込部に挿入した時の外枠差込中心線と、前記ａ’側縁との間隔を、前記格子体板体の板厚とほぼ同寸法とし、
前記Ｂ’スリットを、前記上部折曲線と前記外枠差込中心線との交点を中心とした前記Ａ’スリットと点対称の形状にしたものである。
【００２０】
前記のように構成された請求項６記載の発明は、外枠切込部を形成する内板のＡ’スリットにおいて、上部折曲線と直交するａ’側縁とｂ’側縁の間隔が、少なくともスリット抜き加工に要する幅であり、格子体折曲部基部を外枠切込部に挿入した時の外枠差込中心線と、ａ’側縁との間隔が、格子体板体の板厚とほぼ同寸法であり、
外枠切込部を形成する中板のＢ’スリットが、上部折曲線と外枠差込中心線との交点を中心としたＡ’スリットと点対称の形状であるため、
上部折曲線で折曲された内板と中板の切込部において、Ａ’スリットとＢ’スリットが重ならない部分と重なる部分とがあり、重なる部分の幅が、格子体板体の板厚のほぼ２倍分の幅となり、格子体折曲部基部を外枠切込部に挿入した時、外枠切込部と格子体折曲部間に殆ど隙間がなく、箱体に対して格子体に動きが生ぜず、集塵効率が向上し、騒音が発生しない。
【００２１】
つぎに、請求項７記載の発明は、請求項６記載の発明における外枠板体を上部折曲線で折曲した状態において、Ａ’スリットとＢ’スリットが重ならない部分と重なる部分とがあり、前記重なる部分の幅が、前記格子体板体のほぼ２枚分の幅であるものである。
【００２２】
この請求項７記載の発明は、請求項６記載の発明と同様、外枠切込部と格子体折曲部間に殆ど隙間がなく、箱体に対して格子体に動きが生じない。
【００２３】
つぎに、請求項８記載の発明は、請求項６または７記載の発明における外枠板体を上部折曲線で折曲した状態において、ａ’側縁の開口側端部に斜方向の開口カットを形成したものである。
【００２４】
この場合、スリットのａ’側縁開口側端部に斜方向の開口カットが形成されているため、開口カットがガイドとなり、箱体の外枠切込部への格子体折曲部基部の挿入作業がきわめて容易になる。
【００２５】
つぎに、請求項９記載の発明は、請求項６、７または８記載の発明において、ａ’側縁の底部端から、上部折曲線と平行に格子体板体２枚分とほぼ同寸法の底部ラインを形成したものである。
【００２６】
この場合、スリットの底部に上部折曲線と平行に格子体板体２枚分とほぼ同寸法の底部ラインが形成されているため、箱体の外枠切込部に格子体折曲部基部が接合し、箱体に格子体が安定して組み立てられる。
【００２７】
つぎに、請求項１０記載の発明は、請求項９記載の発明において、底部ラインのａ’側縁と反対側の点からｂ’側縁に対し斜方向の底部カットを形成したものである。
【００２８】
この場合、底部ラインの端から斜方向の底部カットが形成されているため、折曲された内板と中板の外枠切込部において、底部に、底部ラインの両側に傾斜ラインが形成され、格子体折曲部基部が位置決めされ、格子体が箱体により安定して組み立てられる。
【００２９】
つぎに、請求項１１記載の発明は、請求項１ないし１０記載の発明において、スリットの形成がトムソン抜き加工によるものであり、請求項１２記載の発明は、板体が、クラフト紙の片面に導電性の金属薄膜をコーティングして形成されたものである。
【００３０】
この場合、格子体・箱体を構成する板体を折曲して貼り合わせた２枚分の板厚に対し、数倍のスリット最小幅を有するトムソン抜き加工が適し、Ａ電極・Ｂ電極間、或いは箱体に対する格子体の動きを防止する。
【００３１】
【発明の実施の形態】
まず、空気清浄機を図１を参照して説明する。空気清浄機１は例えば家屋の天井２に装着し、やや偏平で直方体状外装ケース３の底面ほぼ中央部に吸気口４を形成し、かつ、この吸気口４に、板金にメッシュ状のカバー５を着脱自在に装着し、左右両側面の底面寄りに吹出口６を形成し、吹出口６の吹出し面にグリル用の金網７を装着し、この金網７の内側に活性炭素繊維等からなる脱臭フィルタ８を装着している。
【００３２】
そして、外装ケース３内中央部の吸気口４の上方に、電気集塵方式の集塵ユニット９を内蔵し、この集塵ユニットと外装ケース３間に、吸気口４と両吹出口６を連通する通気路１０を区画して形成し、かつ、この通気路１０内の集塵ユニット９両側にクロスフロー型のブロアファン１１を装着し、両ブロアファン１１の運転により、室内空気を吸気口４より集塵ユニット９内に吸引して通過させた後、通気路１０を経て両吹出口６より脱臭フィルタ８を通して室内に排気し、循環するようにしている。
【００３３】
また、集塵ユニット９は、図２に示すように、マトリクス状に配置した多数のニードル電極１２間に、ステンレス板等にて形成し格子状に配設された筒状対向電極１３を挿入して装着し、その組合せた電極１２、１３を、枠状のフレーム１４内に収納して構成している。
【００３４】
前記ニードル電極１２は、例えばステンレス板を帯状に成形し、その先端に複数の放電極１５を一体形成した放電部１６と、この放電部１６を支持するアルミ材等で形成した支持部１７とから構成している。
【００３５】
つぎに、本発明の実施の１形態を図３ないし図１２を参照して説明する。対向電極１３は、Ａ電極１８、Ｂ電極１９及び外枠電極２０により構成され、Ａ電極１８、Ｂ電極１９の格子体板体１８ａ、１９ａ及び外枠電極２０の箱体板体２０ａは、芯材となるクラフト紙の片面に導電性の金属薄膜（例えばアルミ製）をコーティングして形成され、表面が導電層になっている。前記金属薄膜の材質は、導電性を有する金属であればよく、銅や鉄でもよい。
【００３６】
Ａ電極１８、Ｂ電極１９の格子体板体１８ａ、１９ａは、展開図の図３Ａ、Ｂに示すように、上部、下部の両側に縦方向の折曲部１８ｂ、１９ｂを介して折片１８ｃ、１９ｃが突設され、折曲部１８ｂ、１９ｂに外側基部を残して内側に切り込み１８ｄ、１９ｄが形成され、板体１８ａは上部・下部に複数個の格子体切込部１８ｅが縦方向に形成され、板体１９ａは中央部に複数個の切込部１９ｅが縦方向に形成されている。
【００３７】
そして、横方向の中央部折曲線１８ｆ、１９ｆで導電層が外側になるよう、図４Ａ、Ｂに示すように折曲して貼り合わせ、各切込部１８ｅ、１９ｅが重なり、中央部折曲線１８ｆ、１９ｆを下側にし、Ａ電極１８は上部に切込部１８ｅが位置し、Ｂ電極１９は下部に切込部１９ｅが位置する。
【００３８】
つぎに、図５に示すように、並設したＡ電極１８の各切込部１８ｅに、並設したＢ電極１９の各切込部１９ｅを互いに差し込んで格子体２１を組み立て、上部に位置した各折曲片１８ｃ、１９ｃを外方へ９０度折曲する。
【００３９】
ここで、格子体切込部１８ｅ、１９ｅを形成するスリットを、切込部１９ｅにつき、拡大図の図６を参照して説明する。
【００４０】
同図Ａに示すように、Ｂ電極１９格子体板体１９ａの格子体切込部１９ｅを形成するスリットは、中央部折曲線１９ｆ両側を、Ａスリット１９ｇａ・Ｂスリット１９ｇｂとし、Ａスリット１９ｇａの中央部折曲線１９ｆと直交する両側縁を、ａ側縁１９ｈａ・ｂ側縁１９ｈｂとし、ａ側縁１９ｈａとｂ側縁１９ｈｂとの間隔を、少なくともスリット抜き加工、例えばトムソン抜き加工に要する幅Ｌとし、Ａ電極１８・Ｂ電極１９の格子体切込部１８ｅ・１９ｅを差し込んだ時の格子体差込中心線Ｓと、ａ側縁１９ｈａとの間隔を、格子体板体１８ａ・１９ａの１枚分の板厚とほぼ同寸法とする。
【００４１】
つぎに、同図Ｂに示すように、ａ側縁１９ｈａの上端、即ち格子体板体１９ａを中央部折曲線１９ｆで折曲した状態において、ａ側縁１９ｈａの開口側端部に斜方向の開口カット１９ｉを形成する。
【００４２】
さらに、同図Ａにおいて、ａ側縁１９ｈａの底部端から、中央部折曲線１９ｆと平行に格子体板体２枚分とほぼ同寸法の底部ライン１９ｊを形成し、底部ライン１９ｊのａ側縁１９ｈａと反対側の点から、ｂ側縁１９ｈｂに対し斜方向の底部カット１９ｋを形成する。
【００４３】
そして、前記Ｂスリット１９ｇｂを、中央部折曲線１９ｆと格子体差込中心線Ｓとの交点Ｋを中心としたＡスリット１９ｇａと点対称の形状にする。
【００４４】
つぎに、同図Ｂは、図４Ｂとは異なり、図６Ａの上側を向う側に折曲したものであり、図６Ｂに示すように、格子体板体１９ａを中央部折曲線１９ｆで折曲した状態において、Ａスリット１９ｇａとＢスリット１９ｇｂが重ならない部分と重なる部分とがあり、重なる部分の幅が、格子体板体１９ａのほぼ２枚分の幅になっている。
【００４５】
一方、図３Ａに示すＡ電極１８格子体板体１８ａの格子体切込部１８ｅは、同図Ｂに示す格子体板体１９ａの格子体切込部１９ｅの上側が下側に、下側が上側にそれぞれ移行したものであり、格子体板体１８ａを中央部折曲線１８ｆで折曲した状態において、格子体板体１９ａと同様、上側・下側のスリットの重なる部分の幅が、格子体板体１８ａの板厚のほぼ２枚分の幅となる。
【００４６】
従って、図６Ｃに示すように、折曲された格子体板体１８ａの切込部１８ｅに、折曲された格子体板体１９ａの切込部１９ｅを差し込んで格子体２１を組み立てた場合、Ａ電極１８・Ｂ電極１９間に殆ど隙間がなく、Ａ電極１８・Ｂ電極１９に動きが生ぜず、集塵効率が向上し、騒音が発生しない。
【００４７】
また、スリットのａ側縁１８ｈａ・１９ｈａ開口側端部に斜方向の開口カット１８ｉ・１９ｉが形成されているため、両開口カット１８ｉ・１９ｉがガイドとなり、Ａ電極１８・Ｂ電極１９の格子体切込部１８ｅ・１９ｅを互いに差し込む作業がきわめて容易になる。
【００４８】
さらに、両切込部１８ｅ・１９ｅのスリット底部に、中央部折曲線１８ｆ・１９ｆと平行に格子体板体２枚分とほぼ同寸法の底部ライン１８ｊ・１９ｊが形成されているため、Ａ電極１８・Ｂ電極１９の切込部１８ｅ・１９ｅ、即ちスリットの底部が互いに接合し、両電極１８・１９が格子体２１に安定して組み立てられる。
【００４９】
その上、斜方向の底部カット１８ｋ・１９ｋが形成されているため、格子体板体１８ａ・１９ａを折曲した状態において、両電極１８・１９の切込部１８ｅ・１９ｅの底部に、底部ライン１８ｊ・１９ｊの両側に傾斜ラインが形成され、両電極１８・１９の切込部１８ｅ・１９ｅの底部が位置決めされ、両電極１８・１９が格子体２１により安定して組み立てられる。
【００５０】
一方、外枠電極２０の外枠板体２０ａは、展開図の図７Ａに示すように、箱体２２の四面の外板２０ｂが横方向に連続し、各外板２０ｂの下端の下部折曲線２０ｃを介して縦長さが外板２０ｂとほぼ同じ長さの内板２０ｄが設けられ、各内板２０ｄの下端の上部折曲線２０ｅを介し、内板２０ｄの約半分の短い長さの中板２０ｆが設けられ、上部折曲線２０ｅの上・下位置に複数個の外枠切込部２０ｇが形成されている。
【００５１】
また、外板２０ｂの上端に押え片２０ｈが突出して設けられ、端部の内板２０ｄの外端にのりしろ２０ｉが設けられ、隣接する各内板２０ｄ・中板２０ｆ間に切り込み２０ｊが形成され、図７Ａでは板体２０ａの裏側に導電層が形成されている。
【００５２】
そして、上部折曲線２０ｅで中板２０ｆを折曲して内板２０ｄに当接し、図７Ｂに示すように、下部折曲線２０ｃで内板２０ｄを外板２０ｂ側に折曲し、外板２０ｂと内板２０ｄの下部当接部を貼り合わせ、中板２０ｆを外板２０ｂに当てがう。
【００５３】
つぎに、隣接する外板２０ｂ間の折曲線２０ｋで４つ折りし、図８に示すように箱状にし、のりしろ２０ｉを貼り付けて箱体２２を形成する。
【００５４】
そして、図８に示す箱体２２に、図５に示す格子体２１を挿入するとともに、格子体板体１８ａ、１９ａの折曲部１８ｂ、１９ｂの上側基部を外枠切込部２０ｇに挿入し、各折曲片１８ｃ、１９ｃを中板２０ｆと外板２０ｂとの間に挿入し、折曲片１８ｃ、１９ｃの導電層を中板２０ｆの導電層に当接し、Ａ電極１８、Ｂ電極１９を外枠電極２０に電気的に接続する。
【００５５】
つぎに、図９及び図１０に示すように、押え片２０ｈを内側に折曲して内板２０ｄに貼り合わせ、折曲片１８ｃ、１９ｃを内板２０ｄ、中板２０ｆを介して押え、前記折曲片１８ｃ、１９ｃの導電層と中板２０ｆの導電層との接続を強固にし、かつ、箱体２２と格子体２１とを一体状態にする。
【００５６】
ここで、図１０は図９のＶ−Ｖ’線断面図、図１１Ａは図９のＴ−Ｔ’線断面図、図１１Ｂは同じくＵ−Ｕ’線断面図であり、図１１におけるハッチングは導電層２３を示し、（１）ないし（６）は外枠電極２０の外面導電層２３に印加された電圧の導通状態を示し、外枠電極２０の外面に電圧を印加することにより、折曲片１８ｃ、１９ｃを通じて各Ａ電極１８、Ｂ電極１９に電圧が印加され、対向電極１３に印加される。
【００５７】
この対向電極１３は、図９、図１０に示す四角筒の形状を有するが、押え付けて菱形の偏平な折り畳み形状にすることができ、拡開・折り畳み自在であり、不使用の保存時には、折り畳んで菱形の偏平状態にでき、かさが小さく、保存にスペースをとらず、保存を容易にすることができる。
【００５８】
ここで、外枠切込部２０ｇを形成するスリットを、拡大図の図１２を参照して説明する。
同図Ａに示すように、内板２０ｄ、中板２０ｆに外枠切込部２０ｇを形成するスリットを、Ａ’スリット２０ｌａ・Ｂ’スリット２０ｌｂとし、Ａ’スリット２０ｌａの上部折曲線２０ｅと直交する両側縁を、ａ’側縁２０ｍａ・ｂ’側縁２０ｍｂとし、ａ’側縁２０ｍａとｂ’側縁２０ｍｂとの間隔を、少なくともスリット抜き加工、例えばトムソン抜き加工に要する幅Ｌとし、格子体折曲部１８ｂ・１９ｂ基部を外枠切込部２０ｇに挿入した時の外枠差込中心線Ｓ’と、ａ’側縁２０ｍａとの間隔を、格子体板体１８ａ・１９ａの１枚分の板厚とほぼ同寸法とする。
【００５９】
つぎに、ａ’側縁２０ｍａの上部折曲線２０ｅ側の端部（後述の開口側端部）に斜方向の開口カット２０ｎを形成し、ａ’側縁２０ｍａの開口カット２０ｎの反対側端（後述の底部端）から上部折曲線２０ｅと平行に格子体の板体１８ａ・１９ａ２枚分とほぼ同寸法の底部ライン２０ｏを形成し、底部ライン２０ｏのａ’側縁２０ｍａと反対側の点から、ｂ’側縁２０ｍｂに対し斜方向の底部カット２０ｐを形成する。
【００６０】
そして、Ｂ’スリット２０ｌｂを、上部折曲線２０ｅと外枠差込中心線Ｓ’との交点Ｋ’を中心としたＡ’スリット２０ｌａと点対称の形状にする。
【００６１】
図１２Ｂは、内板２０ｄ・中板２０ｆを上部折曲線２０ｅで折曲したものであり、同図Ｂに示すように、格子体２１の場合と同様、Ａ’スリット２０ｌａ・Ｂ’スリット２０ｌｂが重ならない部分と重なる部分とがあり、重なる部分の幅が、格子体板体１８ａ・１９ａのほぼ２枚分の幅になっている。
【００６２】
従って、外枠切込部２０ｇに格子体２１の折曲部１８ｂ・１９ｂ基部を挿入した時、箱体２２と格子体２１の接合部における外枠切込部２０ｇと切り込み１８ｄ・１９ｄ間に殆ど隙間がなく、箱体２２に対し格子体２１に動きが生ぜず、集塵効率が向上し、騒音が発生しない。
【００６３】
また、外枠切込部２０ｇのａ側縁２０ｍ開口側端部に斜方向の開口カット２０ｎが形成されているため、両側の開口カット２０ｎがガイドとなり、箱体２２の切り込み１８ｄ・１９ｄを外枠切込部２０ｇに挿入する作業が容易になる。
【００６４】
さらに、スリット２０ｌａ・２０ｌｂの底部に、上部折曲線２０ｅと平行に格子体板体２枚分とほぼ同寸法の底部ライン２０ｏが形成されているため、外枠切込部２０ｇ底部と箱体の切り込み１８ｄ・１９ｄ底部とが接合し、箱体２２に格子体２１が安定して挿入される。
【００６５】
その上、斜方向の底部カット２０ｐにより、格子体２１の折曲部１８ｂ・１９ｂが位置決めされ、より安定する。
【００６６】

BACKGROUND OF THE INVENTION
