Description

【０００１】
【発明の属する技術分野】
本発明は、電気掃除機の全体構造に関するものであり、特に吸込具の使用性向上に関するものである。
【０００２】
【従来の技術】
従来の吸込具１の構成を図１１を用いて説明する。従来の吸込具１では、把手部１６の左右方向に回動力を加え操作することで、図１１（ａ）の状態から把手部１６の先端に取り付けられた吸込具１が回動し、前記把手部１６を持ち清掃している使用者から見ると図１１（ｂ）の状態のような縦長状態となり、狭い場所に吸込具１を進入させたり、あるいは横壁ぎわの掃除を行うことが可能であった。また、吸込部４のある程度後方に位置する部分にはローラーなどによって構成される支持部７が設けられており、吸込具１を前後させる際に吸込部４を被掃除面に対し水平に保つ働きを担っていた（例えば、特許文献１参照。）。

【０００４】
【発明が解決しようとする課題】
しかしながら上記従来の構成では、吸込部４の回動中心が吸込部４の中心より大きくずれていること、また吸込部４後方に前述した支持部７が必要であることから、縦長状態にした際に吸込具１の横幅が大きくなってしまい、狭い隙間では吸込具１の先端部分しか吸込具１を進入させることができなかった。
【０００５】
本発明は上記課題を解決し、吸込具の使用性を向上し、小型軽量で使用性の高い電気掃除機用吸込具とそれを用いた電気掃除機を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記目的を達成するために本発明は、被掃除面上の塵埃を吸引する開口部を有する吸込部と、一端を前記吸込部の上方にて前記吸込部に接続され他端側に接続管を有する連結部と、前記吸込部内に設けた塵埃を掻き上げるアジテーターと、前記アジテータを駆動させる電動機とを備え、前記開口部と前記連結部と前記接続管は吸引した塵埃を移送する通路部を有し、前記連結部は、前記吸込部の長手方向の中心軸と、前記接続管の長手方向の中心軸が略平行になるまで、前記被掃除面と略水平方向に前記吸込部に対して回動可能にすると共に、前記電動機は吸込部内のアジテーター上方であって、前記連結部を中心とした長手方向側の片方の略端部に配置して、連結部が吸込部に対し被掃除面と略水平方向に回動し、前記吸込部の長手方向の中心軸と、前記接続管の長手方向の中心軸が略平行となったとき、連結部は、電動機が配されていない方の吸込部の上方に位置する構成とした電気掃除機用吸込具としてあり、前記連結部は前記吸込部の上方にて前記吸込部に対し接続されているため、前記連結部が、前記被掃除面と略水平方向に前記吸込部に対して回動し、前記吸込部の長手方向の中心軸と、前記接続管の長手方向の中心軸が略平行になったときには、前記連結部および前記接続管も前記吸込部の上方に位置する形態となるため、前記吸込部の左右両面を壁面に密着させることができ、隅にたまりやすい塵埃をすべて吸引することが可能となり、しかも吸込部に対する回動力を加えたときでも吸込部は安定してその位置を保てるとともに、高さや幅の狭いスペースまで、吸込具を挿入することが可能となり、すべての清掃形態において、使用性が高くかつ集塵性能のよい電気掃除機用吸込具を提供できる。
【０００７】
【発明の実施の形態】
本発明の請求項１記載の発明は、被掃除面上の塵埃を吸引する開口部を有する吸込部と、一端を前記吸込部の上方にて前記吸込部に接続され他端側に接続管を有する連結部と、前記吸込部内に設けた塵埃を掻き上げるアジテーターと、前記アジテータを駆動させる電動機とを備え、前記開口部と前記連結部と前記接続管は吸引した塵埃を移送する通路部を有し、前記連結部は、前記吸込部の長手方向の中心軸と、前記接続管の長手方向の中心軸が略平行になるまで、前記被掃除面と略水平方向に前記吸込部に対して回動可能にすると共に、前記電動機は吸込部内のアジテーター上方であって、前記連結部を中心とした長手方向側の片方の略端部に配置して、連結部が吸込部に対し被掃除面と略水平方向に回動し、前記吸込部の長手方向の中心軸と、前記接続管の長手方向の中心軸が略平行となったとき、連結部は、電動機が配されていない方の吸込部の上方に位置する構成とした電気掃除機用吸込具としてあり、前記連結部は前記吸込部の上方にて前記吸込部に対し接続されているため、前記連結部が、前記被掃除面と略水平方向に前記吸込部に対して回動し、前記吸込部の長手方向の中心軸と、前記接続管の長手方向の中心軸が略平行になったときには、前記連結部および前記接続管も前記吸込部の上方に位置する形態となるため、前記吸込部の左右両面（吸込部の長手方向の中心軸と接続管の長手方向の中心軸が略平行になった状態において）を壁面に密着させることができ、隅にたまりやすい塵埃をすべて吸引することが可能となり、すべての清掃形態において、使用性が高くかつ集塵性能のよい電気掃除機用吸込具を提供できる。
【０００８】
また、前記連結部が、前記被掃除面と略水平方向に前記吸込部に対して回動し、前記吸込部の長手方向の中心軸と、前記接続管の長手方向の中心軸が略平行になったときには、前記連結部および前記接続管も前記吸込部の上方に位置する形態となるため、アジテーターの回転音の吸込部上方への透過音を低減できる。
【０００９】
また、前記電動機は前記アジテーターの上方、いわゆる吸込部の上方に配置しているので、吸込部の前後幅が小さくなり、更に電動機は吸込部内のアジテーター上方であって、前記連結部を中心とした長手方向側の片方の略端部に配置して、連結部が吸込部に対し被掃除面と略水平方向に回動し、前記吸込部の長手方向の中心軸と、前記接続管の長手方向の中心軸が略平行となったとき、連結部は、電動機が配されていない方の吸込部の上方に位置する構成としたので、略水平方向への回転は重量の大きい電動機が内蔵されている側と逆の方向へとなり、吸込部に対する回動力を加えたときでも吸込部は安定してその位置を保てるとともに、高さや幅の狭いスペースまで、吸込具を挿入することが可能となり、すべての清掃形態において、使用性が高くかつ集塵性能のよい電気掃除機用吸込具を提供できる。
【００１０】
本発明の請求項２記載の発明は、連結部または接続管に取り付けられ被掃除面に接することで前記連結部または前記接続管を支持する支持部を備え、前記吸込部の長手方向の中心軸と、前記接続管の長手方向の中心軸が略平行になるまで、前記連結部が前記吸込部に対して被掃除面と略水平方向に回動したとき、前記支持部が前記吸込部の外側に位置するよう構成したもので、連結部が、前記被掃除面と略水平方向に前記吸込部に対して回動し、前記吸込部の長手方向の中心軸と、前記接続管の長手方向の中心軸が略平行になったときには、前記支持部は前記吸込部の後方に位置することとなり、前記吸込部の左右両面（吸込部の長手方向の中心軸と接続管の長手方向の中心軸が略平行になった状態において）を壁面に密着させることができ、隅にたまりやすい塵埃をすべて吸引することが可能となり、すべての清掃形態において、使用性が高くかつ集塵性能のよい電気掃除機用吸込具を提供できる。
【００１１】
また、被掃除面が毛足の長い絨毯などの摩擦の大きいものであった場合では、吸込具を前方に押し出す際に吸込部の前方が被掃除面と突っかかり、前につんのめる形となり吸込部が被掃除面より浮いてしまうのを防止できるとともに、逆に吸込部を手前に引き寄せる際には、吸込部の後方が被掃除面に引っかかり吸込部の前方が浮き上がってしまうのを防止できる。
【００１２】
本発明の請求項３記載の発明は、接続管は前記接続管の長手方向の中心軸が被掃除面と略平行となる状態から、前記接続管の長手方向の中心軸が被掃除面と略垂直となる状態まで前記連結部に対し回動可能なもので、接続管は前記接続管の長手方向の中心軸が被掃除面と略平行となる状態のときには、高さの低い省スペース空間の清掃が可能であるとともに、前記接続管の長手方向の中心軸が被掃除面と略垂直となる状態のときには、清掃をしないときの設置等において、省スペース空間にて設置が可能である。
【００１３】
本発明の請求項４記載の発明は、支持部の被掃除面に接する部分を軟質体で構成したもので、接続管を有する連結部を前記被掃除面と略水平方向に前記吸込部に対して回動させる際に、被掃除面および吸込部に傷を付けるのを防ぐことが可能となる。
【００１４】
本発明の請求項５記載の発明は、請求項１〜４のいずれか１項に記載の電気掃除機用吸込具の連通路が、吸引風を発する電動送風機と連通するよう構成した電気掃除機で、吸込具の使用性を向上し、小型軽量で使用性の高い電気掃除機用吸込具とそれを用いた電気掃除機を提供できる。
【００１５】
【実施例】
以下、本発明の一実施例について、図１〜図１０を用いて説明する。
【００１６】
図１は電気掃除機用吸込具の側面図である。
【００１７】
塵埃を吸引する開口部１２を下面に有する吸込部４の上面に、連結部５の一端が被掃除面２３と略水平方向に回動可能に取り付けられており、連結部５には支持部７が取り付けられている。前記支持部７は、表面がエラストマーかあるいはポリプロピレンか塩化ビニル等の軟質樹脂あるいは起毛布等の軟質材から形成され、被掃除面２３に接することで、前記連結部５を支持する回転可能なローラー１７を有している。また、前記連結部５の他端には接続管６が取り付けられている。なお、支持部７は前記接続管６に取り付けられていても良い。開口部１２から連結部５、さらに接続管６にかけては、前記開口部１２から吸引した塵埃を移送する通路部８を有している。
【００１８】
図２、図３、図４はそれぞれ電気掃除機用吸込具の上面図、正面図および内部構成図である。
【００１９】
吸込部４の上方突出部の中には電動機１３が内蔵されており、この動力によりベルト２４を介してアジテーター１４が駆動され回動し、絨毯などの被掃除面に付着した塵埃を強力に掻き出し、被掃除面より塵埃を遊離させ吸引することが可能となる。またアジテーター１４の上方に電動機１３が配置されているため、吸込部４の前後幅が小さくなっている。また、前記吸込部４の長手方向の中心軸４ａと接続管６の長手方向の中心軸６ａが略垂直となるよう設けてある。
【００２０】
図５および図６はそれぞれ電気掃除機用吸込具において吸込部の長手方向の中心軸と、接続管の長手方向の中心軸が略平行になるよう連結部が吸込部に対して被掃除面と略水平方向に回動したときの側面図および上面図である。
【００２１】
吸込部４の長手方向の中心軸４ａと、接続管６の長手方向の中心軸６ａが略平行（本実施例においては一致）になるまで、連結部５が前記吸込部４に対して被掃除面２３と略水平方向に回動可能に取り付けられているため、連結部５に吸込部４に対する回動力を加えることで吸込具１を横方向（吸込部４の長手方向の中心軸４ａ方向）にて使用することが可能となる。このとき、前記連結部５と前記接続管６は前記吸込部４の横幅内に収まる形態となっている。さらに、連結部５が吸込部４に対して被掃除面２３と略水平方向に回動し、前記吸込部４の長手方向の中心軸４ａと、前記接続管６の長手方向の中心軸６ａが略平行（本実施例においては一致）となったとき、支持部７は、前記吸込部４の後方（吸込部４の長手方向の中心軸４ａと、前記接続管６の長手方向の中心軸６ａが略平行とした状態において）に位置することとなるとともに、接続管６は前記接続管６の長手方向の中心軸６ａが被掃除面２３と略垂直となる状態から、前記接続管６の長手方向の中心軸６ａが被掃除面２３と略平行となる状態まで前記連結部５に対し回動可能なため、高さや幅の狭いスペースまで、吸込具１を挿入することが可能となり、すべての清掃形態において、使用性が高くかつ集塵性能のよい電気掃除機用吸込具を提供できる。
【００２２】
このときの回動方向としては、重量の大きい電動機１３が内蔵されている側と逆の方向へなり、連結部５に吸込部４に対する回動力を加えたときでも吸込部４は安定してその位置を保てる。また、電動機１３はアジテーター１４の上方に配置されているため、前記状態とした際の吸込部４の長手方向の中心軸４ａを中心とする横幅を小さく抑えられている。
【００２３】
図７、図８は電気掃除機用吸込具の底面からの内部構成図である。
【００２４】
連結部５と吸込部４が接続する部分に、溝部１９が互いに９０度をなす位置に２カ所設けられており、この溝部１９に入り込み、連結部５に回動を抑制する金属製あるいは樹脂で構成された板バネからなる保持手段１５が取り付けられている。連結部５が吸込部４に対して被掃除面２３と略水平方向に回動し、前記吸込部４の長手方向の中心軸４ａと、前記接続管６の長手方向の中心軸６ａが略平行（本実施例においては一致）場合あるいは吸込部４の長手方向の中心軸４ａと、前記接続管６の長手方向の中心軸６ａが略垂直となっている際には、この溝部１９に保持手段１５が入り込み、吸込部４が掃除機使用中に家具などに衝突するなどで多少の外力を受けた場合でも、現在の位置を保持する役割を果たしている。
【００２５】
また、支持部７は連結部５に設けられているため、吸込部４の長手方向の中心軸４ａと接続管６の長手方向の中心軸６ａが略垂直である通常の清掃状態では、前記支持部７により吸込部４が浮き上がったりすることなく使用性が高いとともに、接続管６を有する連結部５を前記被掃除面２３と略水平方向に前記吸込部４に対して回動させた場合には、前記支持部７が前記吸込部４の外側に位置するよう構成してあるため、吸込部４の左右両面を壁面に密着させることができ、隅にたまりやすい塵埃をすべて吸引することが可能となり、すべての清掃形態において、使用性が高くかつ集塵性能のよい電気掃除機用吸込具を提供できるものである。
【００２６】
図９、図１０は電気掃除機の全体図を表している。
【００２７】
２は吸引した塵埃を集塵する集塵室、８は吸引した塵埃を前記集塵室２に移送する通路部、１６は把手部、２０は電源用電池、２２は吸引風を発する電動送風機で前記通路部８を介して吸込具１と連通している。接続管６は前記接続管６の長手方向の中心軸６ａが被掃除面２３と略平行となる状態だと、図のように、ベッドやテーブルの下にも吸込具１を進入させることが可能であるため、しっかりと被掃除面上の塵埃を吸引可能である。また、前記接続管６の長手方向の中心軸６ａが被掃除面２３と略垂直となる状態まで回動させたときには、図１１のように、清掃をしないときの設置等において、省スペース空間にて設置が可能である。
【００２８】
電気掃除機について、本実施例においては、ほうき型充電式の電気掃除機として説明を行っているが、形式や電源の形態を問わず、一般の電気掃除機全般についても同様な構成を採用可能である。
