Description

【０００１】
【発明の属する技術分野】
本発明は、空気中の粉塵や臭気を捕集する空気清浄機に関し、詳しくは、フィルターの使用を回避しながら捕集効率を高めようとする技術に係るものである。
【０００２】
【従来の技術】
従来、家庭内に発生する粉塵や臭気を捕集、脱臭するための空気清浄機において、本体ケースに外気導入口、吹き出し口をそれぞれ設け、本体ケース内から突出した壁面により形成される渦巻き形状の風洞を設け、空気を吸い込む吸気部が駆動用モータと風洞内に設置されるシロッコファンとを有して構成され、風洞吸込口と外気導入口との間に吸い込まれた空気を浄化するフィルターを備えているものが知られている。
【０００３】
【発明が解決しようとする課題】
上記のような従来の空気清浄機においては、吸気部によって吸い込まれる空気は、風洞と外気導入口の間にある空気浄化用のフィルターを通って吹き出し口から吐き出されるのであり、従来の空気清浄機にはフィルターが必要不可欠なものである。
ところが、長期間使用するとフィルターに粉塵が堆積し、捕集性能の低下や悪臭の発生、または背圧の増加による吸い込み力の低減などが発生するのであり、フィルターを交換する必要があった。
そこで、サイクロンと呼ばれて粉塵を空気の流れにより遠心分離し、フィルターを必要としない集塵手段がある。ところが、この手段では遠心分離方式であることから細かい粒径の粉塵までは捕捉できないという問題がある。
【０００４】
本発明は、上記の問題に鑑みて発明したものであって、粉塵を空気の流れにより遠心分離することができるサイクロンと呼ばれる集塵手段で粉塵を集塵してフィルターの使用を回避しながら、比較的細かい粒径の塵埃を良好に捕集することができ空気清浄機を提供することを課題とするものである。
【０００６】
【課題を解決するための手段】

気をサイクロン部Ｓに吸い込む吸込口１１を複数設け、一個ないし複数の吸込口１１に、±の交流波形を流すことにより＋放電と−放電を交互に発生させることができる電極１２を設けたことを特徴とするものである。このような構成によれば、＋放電と−放電を交互に発生させることができるようになり、吸入された粉塵が吸込口１１を通るときに、＋放電時では＋に帯電され、−放電時では−に帯電され、円錐筒状の外筒４を螺旋状に旋回下降するうちに＋と−に帯電された粉塵が衝突することによってお互いが結合して凝集され、粉塵の粒径は拡大さ
れるのであり、遠心力により効果的に分離されてダストボックス５に堆積するのであり、細かい粒径の粉塵まで捕集することができる。請求項３の発明においては、外気導入口２より導入された外気をサイクロン部Ｓに吸い込む吸込口１１を複数設け、一個ないし複数の吸込口１１に＋放電をする電極１２を設け、外筒４の円錐部内側表面に導電性材料の金属メッキ部１３を形成して接地したことを特徴とするものである。このような構成によれば、吸引される粉塵が吸込口１１を通るときに、＋に帯電され、円錐筒状の外筒４を螺旋状に旋回下降するうちに接地された金属メッキ部１３に付着して凝集され、細かい粒径の粉塵まで捕集することができる。
【０００７】
請求項４の発明においては、金属メッキ部１３の内壁に沿ってアルミ箔１４を装着したことを特徴とするものである。このような構成によれば、帯電した粉塵はアルミ箔１４に付着するのであり、アルミ箔１４を交換するだけで長期間の使用による汚れの付着、及び捕集性能の低下を防止することができ、メンテナンスが
容易になる。
【０００８】

を形成して接地して円錐内外筒１６、１７間の粉塵の通路に電界を発生させるようにしたから、吸引された塵埃が粉塵の通路を螺旋状に旋回下降するうちに接地された金属メッキ部１３に付着して凝集され、細かい粒径の粉塵まで捕集することができる。

【００１７】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。図１（ａ）は上面図、同図（ｂ）は側断面図である。図２は空気の流れを説明する側断面図である。
【００１８】
空気清浄機Ａは、図１に示すように、例えば、角筒状の本体ケース１の一側面より筒状の外気導入口２を突出し、本体ケース１の上部に吹き出し口３を設け、本体ケース１の内部に下方が小径となる円錐筒状の外筒４を設け、外筒４の内方上部に内筒６を設け、内筒６の上方にモータ７と吸気ファン８を各々設けてサイクロン部Ｓを構成し、外筒４の下方にダストボックス５を配設し、外気導入口２を外筒４の内部に連通し、外気導入口２より吸入された外気中の塵埃がサイクロン部Ｓにおいて遠心分離されてダストボックス５に集塵し、塵埃を分離した空気を吹き出し口３から吹き出すようにしている。
【００１９】
ダストボックス５は引き出し形態に構成していて、堆積して集塵した粉塵を捨てることができるようにしている。なお、本例では外気導入口２の奥部がサイクロン部Ｓの吸入口１１となっている。
【００２０】
吸入した空気と粉塵の流れは、図２の矢印に示すように、外気導入口２（吸込口１１）から外筒４の円周方向に流入し、外筒４の円錐筒部１５を螺旋状に旋回しながら下降して本体ケース１の下部のダストボックス５まで進んでいく。この時、比較的大きな粉塵は遠心力により空気から分離されてダストボックス５に堆積するのであり、細かい粉塵は外筒４の壁面に移行する。その後、気流は反転して上昇し、吸気部９をへて内筒６の上部より流出し、吹き出し口３より吹き出される。
【００２１】
図３に示すように、外気導入口２、つまり、サイクロン部Ｓの吸込口１１、１１を略対向させて複数設け、その一方に＋放電、片方に−放電をする電極１２、１２を各々設けてある。図４に示すように、電極１２は、一対の対極板２７、２７に放電線２８を配設して、吸込口１１への空気の流入方向に対して垂直に電圧を印加するようにしている。
【００２２】
しかして、複数の放電線２７、２７のうち、一方には図５（ａ）に示すように、例えば、ＤＣ約＋５ＫＶの電圧を印加し、もう一方には同図（ｂ）に示すように、ＤＣ約−５ＫＶの電圧を印加してある。これにより、吸引される外気中の粉塵が吸込口１１を通るときに、＋放電側では＋に帯電され、−放電側では−に帯電されるのであり、円錐筒状の外筒４を螺旋状に旋回下降するうちに＋と−に帯電された粉塵が衝突することによってお互いが結合して凝集され、粉塵の粒径は拡大されるのであり、遠心力により効果的に分離されてダストボックス５に堆積するのであり、細かい粒径の粉塵まで捕集することができるのである。
【００２３】
図６は他の実施の形態を示し、但し、本実施の形態の基本構成は上記実施の形態と共通であり、共通する部分には同一の符号を付して説明は省略する。
【００２４】
本実施の形態においては、サイクロン部Ｓの吸込口１１に電極１２が設けてあり、この電極１２は図４に示す構成と同様であり、その放電線２８には図７に示すように、±の交流波形が印加され、＋放電と−放電を交互に発生させることができるようになっている。これにより、吸引される外気中の粉塵が吸込口１１を通過するとき、＋放電時では＋に帯電され、−放電時では−に帯電される。そして、円錐筒状の外筒４を螺旋状に旋回下降するうちに＋と−に帯電された粉塵が衝突することによってお互いが結合して凝集され、粉塵の粒径は拡大されるのであり、遠心力により効果的に分離されてダストボックス５に堆積するのであり、細かい粒径の粉塵まで捕集することができるのである。
【００２５】
図８は更に他の実施の形態を示し、但し、本実施の形態の基本構成は上記実施の形態と共通であり、共通する部分には同一の符号を付して説明は省略する。
【００２６】
本実施の形態においては、サイクロン部Ｓの吸込口１１に図４に示すような電極１２が設けてあり、この放電線２８に図９に示すような電圧を印加することで、＋放電を発生させている。更に、外筒４の円錐筒部１５の内側表面全面には図８に示すように導電性材料の金属メッキ部１３（例：Ｎｉ−ｃｒメッキ）が施され、接地部（グランド）に接続（アース）されている。これにより、吸引される外気中の粉塵が吸込口１１を通過するときに、＋に帯電され、そして、円錐筒状の外筒４を螺旋状に旋回下降するうちに接地部に接続された金属メッキ部１３に付着するのであり、細かい粒径の粉塵まで捕集することができるのである。
【００２７】
図１０は更に他の実施の形態を示し、但し、本実施の形態の基本構成は上記実施の形態と共通であり、共通する部分には同一の符号を付して説明は省略する。
【００２８】
本実施の形態においては、円錐筒部１５の金属メッキ部１３に沿って家庭用のアルミ箔１４を取着することで、帯電した粉塵がアルミ箔１４に付着するのであり、しかして、長期の使用による汚れ（粉塵）の付着、及び捕集性能の低下はアルミ箔１４を交換するだけで済むのである。
【００２９】
図１１は更に他の実施の形態を示し、但し、本実施の形態の基本構成は上記実施の形態と共通であり、共通する部分には同一の符号を付して説明は省略する。
【００３０】
本実施の形態においては、外気導入口２より導入された外気をサイクロン部Ｓに吸い込む吸込口１１を複数設け、一個ないし複数の吸込口１１に＋放電をする電極１２を設け、外筒４の円錐筒部１５を２重筒構造にし、円錐内筒１６の外壁に＋の高電圧を印加し、円錐外筒１７の内表面に導電性材料の金属メッキ部１３（例：Ｎｉ−Ｃｒメッキ）を形成して接地して円錐内外筒１６、１７間の粉塵の通路に電界を発生させるようにしたものである。
【００３１】
しかして、吸引された塵埃が粉塵の通路を螺旋状に旋回下降するうちに接地された金属メッキ部１３に付着して凝集され、細かい粒径の粉塵まで捕集することができるのである。
【００３２】
ところで、以上の実施の形態においては、サイクロン部Ｓの円錐筒部１５及び内面に取着したアルミ箔１４には粉塵が付着するため、長期間使用すると捕集性能が低減してしまい、円錐筒部１５の洗浄又はアルミ箔１４の交換が必要になってくる。しかして、以下の実施の形態においては、サイクロン部Ｓの外筒４における円錐筒部１５を上部円筒部１８と下部円筒部１９とに分割し、上部円筒部１８に対して下部円筒部１９を着脱自在に構成して、円錐筒部１５の下部円筒部１９の洗浄やアルミ箔１４の交換等のメンテナンスを容易におこなうことができる。
【００３３】
図１３は具体的な実施の形態を示し、但し、本実施の形態の基本構成は上記実施の形態と共通であり、共通する部分には同一の符号を付して説明は省略する。

このような構成によれば、下部円筒部１９をねじ結合部において下方に外すことができ、円錐筒部１５の下部円筒部１９の洗浄やアルミ箔１４の交換等のメンテナンスを容易におこなうことができる。
【００３６】
図１４は更に他の実施の形態を示し、但し、本実施の形態の基本構成は上記実施の形態と共通であり、共通する部分には同一の符号を付して説明は省略する。
【００３７】
本実施の形態においては、上部円筒部１８と下部円筒部１９とは分離自在に差し込み接続され、差し込み接続箇所にＯリング２１を配設し、下部円筒部１９はスプリング２０にて上方に付勢されている。
【００３８】
このような構成によれば、下部円筒部１９を差し込み接続箇所において下方に外すことができ、円錐筒部１５の下部円筒部１９の洗浄やアルミ箔１４の交換等のメンテナンスを容易におこなうことができる。
【００３９】
図１５は更に他の実施の形態を示し、但し、本実施の形態の基本構成は上記実施の形態と共通であり、共通する部分には同一の符号を付して説明は省略する。
【００４０】
本実施の形態においては、上部円筒部１８にガイド部２２を設け、下部円筒部１９に被ガイド部２３を形成し、ガイド部２２に被ガイド部２３を水平方向にスライドして分離自在に結合し、下部円筒部１９に取っ手２９を形成している。

図１６は更に他の実施の形態を示し、但し、本実施の形態の基本構成は上記実施の形態と共通であり、共通する部分には同一の符号を付して説明は省略する。
本実施の形態においては、内筒６の吹き出し側にダストセンサー２４を配置し、サイクロン部Ｓが汚れることによって捕集できなかった粉塵が、空気の流れと共に吐き出されるのを検知し、図１７に示すように、ダストセンサー２４の出力が一定レベル（しきい値）以上になると洗浄のサインを出すようにしている。表示部は図示していない。
このような構成によれば、サイクロン部Ｓの汚れによる捕集性能の低下を検知することができ、メンテナンスを促すことができる。
【００４２】
図１８は更に他の実施の形態を示し、但し、本実施の形態の基本構成は上記実施の形態と共通であり、共通する部分には同一の符号を付して説明は省略する。
【００４３】
本実施の形態においては、外筒４の内面の接地されている金属メッキ部１３に対向して検知用リブ２５を設け、検知用リブ２５に＋の高電圧を印加し、その電圧低下を検知して洗浄のサインを表示するようにしたものである。
【００４４】
この場合、図１９（ａ）は未だ金属メッキ部１３が汚れていない初期の状態を示し、電界のみで電流が流れていないので、ＤＣ約５ｋＶの電圧が検知用リブ２５に印加されている。しかし、長期間の使用によって金属メッキ部１３に粉塵が付着し、空気中の湿気によって検知用リブ２５の導体部の高圧より粉塵を介して徴量の電流が流れる。図１９（ｂ）の特性より、電流が流れると印加している電圧が下がる。この電圧降下を（例：４ｋＶ以下）検知し、洗浄サインが出るようになっている。
【００４５】
このような構成によれば、サイクロン部Ｓの汚れによる捕集性能の低下を検知することができ、メンテナンスを促すことができる。
【００４６】
この場合、図１１に示すように、外筒４の円錐筒部１５を２重筒構造にし、円錐内筒１６の外壁に＋の高電圧を印加し、その電圧低下を検知して洗浄のサインを表示するようにしてもよいものである。このような構成によれば、サイクロン部Ｓの汚れによる捕集性能の低下を検知することができ、メンテナンスを促すことができる。
【００４７】
図２０は更に他の実施の形態を示し、但し、本実施の形態の基本構成は上記実施の形態と共通であり、共通する部分には同一の符号を付して説明は省略する。
【００４８】
本実施の形態においては、吸気ファン８の駆動により吸い込まれた外気の吸入流路に脱臭機能を備えた吸着剤２６を付設している。
【００４９】
このような構成によれば、吸い込まれた外気の臭気を吸着剤２６にて脱臭することができ、空気清浄機の機能を高めることができる。
【００５０】
この場合、内筒６にハニカム構造で脱臭機能を備えた吸着剤２６を付設している。このような構成によれば、吸い込まれた外気の臭気を低圧損のハニカム構造の吸着剤２６にて脱臭することができ、風量を低下させずに効率的に脱臭ができる。ハニカム構造の吸着剤２６は、例えば、活性炭をハニカム状に形成するもの、又は、セラミックをハニカム状に形成して消臭剤を添着するもの等がある。
