Description

【０００１】
【産業上の利用分野】
本発明は電気掃除機用吸込具並びに電気掃除機に関するものである。
【０００２】
【従来の技術】
従来この種の吸込具として、特開平５−２６１０４０号公報に示されているような構造のものがあった。以下、図１８および図１９を用いて説明する。
【０００３】
図において、１は吸込具本体で、上部吸込具３と下部吸込具２を結合して構成されたものであり、吸込具本体１の前方内部には下方開口を吸込口４とした吸込室１５が形成してある。この吸込室１５の中央は、吸込具本体１の後方で上部吸込具３、下部吸込具２に狭持された連通管１６、この連通管１６に回転自在に結合された接続管１７に連通し、かつ、この接続管１７には延長管（図示せず）を介して電気掃除機（図示せず）の吸引側のホース（図示せず）に着脱自在に接続される。
【０００４】
前記下部吸込具２内の左右近傍には軸受保持部１８が構成されており、軸受保持部１８内に設けられている軸受１９により回転軸２０が回転可能に設けられている。回転軸２０先端部には円盤１０が圧入固定されており、円盤１０下面にはカットパイル状の紡績布からなる起毛布６が接着固定されている。２２は止め輪で、回転軸２０が軸受１９から抜けるのを防止している。軸保持部１８は、前記円盤１０の外周部と被掃除面との間隔が吸込口４近傍で広く、吸込具本体１左右近傍で狭くなるように傾斜をもたせて軸受１９を保持している。
【０００５】
また第２の従来例として、特開平１−１１４７１４号公報に記されているような構造になっている。以下、図２０を用いて説明する。
【０００６】
塵埃等を吸い込む吸込口４４を有する下部吸込具４２の外周部に堤状の取付座４５を形成し、この取付座４５にはカットパイル状の紡績布からなる起毛布４６が設けられていた。
【０００７】
また、第３の従来例として、実開昭５２−１６２７７８号公報に記されている集塵機能を有するシュウズポリッシャーがあった。以下、図２１を用いて説明する。
【０００８】
図において、５１は電気掃除機に接続されるシュウズポリッシャー本体で、エアータービン５２の回転を減速ギア５３を介してブラシ５４を植毛した円盤５５に位置するものである。５６は電気掃除機に接続するための接続部、５７はエアータービン５２を駆動する通路、５８は円盤５５の外周開口部に通じる吸込通路である。
【０００９】
【発明が解決しようとする課題】
しかし、この様な第１の従来の構造のものでは、傾斜して設けた円盤１０の回転方向を吸込口４付近を起点として考えたとき、被掃除面上で操作すべく往復動作させると吸込口４側から吸込具本体１の外側に向かって円盤１０が回転しており、集塵する前に円盤１０で塵埃を巻き散らしてしまう課題があった。
【００１０】
また、第２の従来の構造のものでは、起毛布４６が下部吸込具４２に一体に設けられているため、極細で高密度である起毛布４６において畳の藺草の塵埃の掃き出し効果や、床面上での細塵を拭き取る効果を充分に出すためには、吸込具を同一箇所で前後に何回も往復させなければならなかった。
【００１１】
また、じゅうたんを掃除する場合、じゅうたんと前記起毛布４６が擦り合うため、吸込具の前後操作に大きな力を要し、操作性が悪くなってしまうという課題があった。
【００１２】
また、第３の従来の構造のものでは、仮に本構成にて、じゅうたん上での掃除に使用した場合においては、じゅうたんと円盤５５が強く摩擦するため重くなり、摩擦力がエアータービン５２の駆動力を越えると円盤５５の回転が止まってしまい、操作性が悪くなってしまうという課題があった。
【００１３】
本発明は上記課題を解決するもので、吸込具の少ない前後動作回数でもって起毛布による掃き出し効果や拭き取り効果を発揮でき、なおかつじゅうたん上においても、軽い操作力で掃除作業を行え、さらに円盤の回転性を良好にし、拭き取り効果を充分発揮できる電気掃除機用吸込具を提供することを目的としている。
【００１４】
【課題を解決するための手段】
上記目的を達成するために、第１の手段は、吸込口を有する吸込具本体と、前記吸込具本体の下面に回転自在に設けられる円盤と、前記円盤下面に設けられる清掃用パッドを備え、前記円盤は吸込口の左右近傍に設けられるとともに、前記円盤の最外周部が前記吸込具本体の左右方向での端部より突出させ、さらに前記円盤の外周部と被掃除面との間隔が吸込口近傍で狭く、吸込具本体の左右端近傍で広くなるように傾斜して構成したものである。

【００１６】
また、第３の手段は、前記吸込具本体の吸込通路を構成する壁材を、軟質材にて構成したものである。
【００１７】
また、第４の手段は、前記吸込具本体の吸込通路を構成する壁材を、軟質材から成るバンパー部材により一体に構成したものである。
【００１８】
また、第５の手段は、前記吸込具本体の吸込通路の断面積を、吸込口近傍では大きく吸込口から遠ざかるに従い小さくしたものである。
【００１９】
また、第６の手段は、前記吸込具本体の吸込通路の一部が前記吸込具本体の内部を通るトンネル状に形成した連絡口を介し、前記吸込具本体の端部に設けられた補助吸込口を設けたものである。
【００２０】
また、第７の手段は、前記吸込具本体の下面にカットパイル状の固定起毛布を設けたものである。
【００２１】
また、第８の手段は、前記円盤外周の吸込具本体側にリブを設け、吸込具本体下面に前記リブと摺動できるリブを設けたものである。
【００２２】
また、第９の手段は、前記円盤と吸込具本体下面との隙間を吸込口の近傍に位置するほど大きくなるように設定したものである。
【００２３】
また、第１０の手段は、前記円盤と吸込具本体下面との隙間に吸込具本体下面よりブラシ体を設け、そのブラシ体は円盤に接するよう設定したものである。
【００２４】
また、第１１の手段は、前記吸込具の円盤と吸込具本体下面との隙間に吸込具本体下面よりブラシ体を設け、そのブラシ体は円盤に接するよう設定し、ブラシ体を導電性の材質にて構成したものである。
【００２５】
また、第１２の手段は、前記吸込具本体の下面にローラーを設けたものである。
【００２６】
また、第１３の手段は、円盤の外周縁部分が、吸込具本体左右および前後の外周縁部分のいずれかより外側に出るように構成したものである。
【００２７】
また、第１４の手段は、円盤の回転中心より放射状に円盤の外周縁部分にまで伸び、下方開口の溝部を形成したものである。
【００２８】
また、第１５の手段は、略円錘形状をした円盤を設けたものである。
また、第１６の手段は、吸込具本体を操作したとき、操作方向にある固形状の塵埃を受けとめるための受け口を複数、円盤外周縁部分に設けたものである。
【００２９】
また、第１７の手段は、円盤を完全に覆い、前記円盤と被連動で自由に回転出来る回転カバーを構成した円盤を設けたものである。
【００３０】
また、第１８の手段は、摩擦係数が高く、弾力性に富む材料を円盤外周縁部分に上下から挟み込むように固定し、巻く構成したものである。
【００３１】
また、第１９の手段は、塵埃を吸引し集塵する電気掃除機の吸引側に連通され、着脱自在に接続される接続管を前記電気掃除機本体の吸引側に、上記第１〜第１８のいずれかの電気掃除機用吸込具が連通するよう着脱自在に接続される電気掃除機としたものである。
【００３２】
【作用】
第１手段によれば、下面に清掃用パッドを備えている回転可能な円盤が被掃除面に対して傾斜させた状態で設けられているため、本吸込具で掃除作業を行った場合、円盤外周部の最も吸込具下面から遠い位置にある清掃用パッドが被掃除面と接触し、さらに吸込具を前移動させることにより前記被掃除面との接触点が基点となり円盤中心部が前方へ移動すると同時に円盤に対して回転力を与えることになり、前記基点は円盤端部を順次移動していき吸込具の前移動に伴い円盤も回転することとなる。
【００３３】
そして、この時円盤の回転中心に対して対称位置にある清掃用パッドは吸込具の進行方向に対して同方向に回転し、清掃用パッドが被掃除面に対して、いわゆる箒ではき掃除をするが如く作用するものである。従って、従来の吸込具のように起毛布を一体に取付たものに比べ、吸込具の前後操作を少ない回数で塵埃の吐き出し効果や拭き取り効果を充分に発揮できるものである。また、円盤が回転することにより被掃除面との摩擦力も小さくなるため、吸込具の前後操作に伴う操作抵抗も軽減され、より軽い操作で掃除作業がおこなえるものである。
【００３４】
そして、円盤及び清掃用パッドを吸込口の左右近傍に設け、かつ、円盤外周部と被掃除面との間隔が吸込口近傍で狭く、吸込具本体の左右端で広くなる方向に傾斜させたため、吸込口に向かい清掃用パッドが被掃除面を掃き出し、拭く、磨くの作用を発生しながら吸込口に掃き出された塵埃が素早く確実に吸引されるため、より効果よく掃除作業がおこなえるものである。
【００３５】
また、第２の手段によれば、前記清掃用パッドにて塵埃を掃き出す前に被掃除面に散乱している塵埃のなかで、吸込口に流れる吸込風により吸引できる塵埃を清掃用パッドにて被掃除面に擦り付けるまえに吸込通路に流れる吸込風により、吸引してしまうものであるため、掃き掃除をしてから、拭く、磨くの工程に入るため、例えば砂等の硬く、被掃除面を傷付けるような塵埃を吸引した後、清掃用パッドで拭く、磨くの動作を行うため、被掃除面を傷つけること無く掃除作業をおこなえるものであり、また吸込通路が吸込具本体の端部までのびているため、壁際に吸込具本体が位置するとき吸込風を壁際まで影響させることができ壁際での吸込性能も確保できるものである。
【００３６】
また、第３の手段によれば、前記吸込通路を形成するリブ体を軟質材（例えばゴム、塩ビ）で構成するため吸込風を吸込具本体の端部まで確実に影響させるためにリブ体を被掃除面と接する位置隙間関係に設定したときにも、被掃除面上に存在する、例えば砂等の硬く被掃除面を傷付ける塵埃を除去するための吸込風の圧力、風速を吸込具本体端部まで効率よく影響させることができるものであり、より被掃除面を傷付けることなく吸込風を吸込具本体端部まで影響させることができ吸込具本体の幅全てでの吸込性能も確保できるものである。
【００３７】
また、第４の手段によれば、前記リブ体を吸込具本体の外周部に設けられているバンパー部材と一体成形することによりリブ体を吸込具本体の外周最短部に設けることが出来るものでありより吸込風を壁際まで影響させることが出来るものであり、また、部品点数も削減できるため安価で高性能な電気掃除機用吸込具を提供できるものである。
【００３８】
また、第５の手段によれば、吸込通路の断面積を吸込口付近より吸込具本体の端部に行くほど徐々に小さくすることにより、円盤外周部と被掃除面との間隔が吸込口近傍で狭く、吸込具本体の左右端で広くなる方向に傾斜させたために、吸込口に向かい清掃用パッドが被掃除面を掃き出し、拭く、磨くの作用を発生しながら吸込口に掃き出された塵埃を素早く確実に吸引させるために必要な吸込風の圧力、風速を円盤下面の清掃用パッドと被掃除面との間隔が大きくなる吸込具本体端部でも吸込口付近と同等または吸込口付近以上の吸込風の圧力、風速を得れるように、清掃用パッドと被掃除面との隙間より流入する吸込風の量を加えた量より、若干多い量の吸込風を吸込通路内の吸込風より減量できる吸込通路内の断面積としているため、吸込通路間での吸込風の圧力、風速は吸込口付近と吸込具本体端部で同等以上になり清掃用パッドと被掃除面の間にも吸込風を流すことができるため、被掃除面より清掃用パッドにて除去した塵埃は清掃用パッドにて被掃除面に擦り付けることなく、素早く吸込風と共に吸込口に導かれ集塵されるものであり、高性能な電気掃除機用吸込具を提供できるものである。
【００３９】
また、第６の手段によれば、吸込具の吸込通路の一部が吸込具本体の内部を通るトンネル状に形成した連絡口を介し、吸込具本体の端部に設けられた補助吸込口を有することにより、吸込風の圧力、風速をトンネル内にて保持し補助吸込口にて吸込具本体端部より被掃除面の塵埃を効率良く集塵出来る、高性能な電気掃除機用吸込具を提供できるものである。
【００４０】
また、第７の手段によれば、吸込具本体の幅において円盤状の清掃用パッドが接しない部分に位置させた固定起毛布が清掃用パッドにて清掃されない部分を清掃するものであり、さらに清掃用パッドが均一に被掃除面に接するように吸込具本体と被掃除面との平衡性を保つことができるもので吸込具本体の幅全てを清掃することができる効率の良い高性能な電気掃除機用吸込具を提供できるものである。
【００４１】
また、第８の手段によれば、吸込具本体下面と円盤状の清掃用パッドにそれぞれリブ体を設けており、そのリブ体はそれぞれ摺動可能な状態にて接触しているため回転軸中心への塵埃の進入を防止すると共に円盤に必要以上の付加が加わった場合にはリブ体同士が圧接することにより回転軸に付加力を伝えることがないため回転軸の破壊を防止できるものであり回転板の動作を確実に行える耐久性の良い電気掃除機用吸込具を提供できるものである。
【００４２】
また、第９の手段によれば、吸込具本体において円盤状の清掃用パッドと吸込具本体下面との隙間を吸込口の近傍に位置するほど大きくなるように設定したことにより、吸込具外周部より進入しようとする塵埃は吸込具外周部においての吸込具本体下面と清掃用パッドとの隙間より大きい塵埃は前記隙間に入り込むこと無く吸込通路より集塵され、前記隙間より小さい塵埃は前記隙間より進入するが前記隙間は吸込具外周部より吸込口に近ずくほど大きく設定されているため途中で係止することなく吸込口に導かれ集塵されるものであり回転軸中心への塵埃の進入を防止するものであり回転板の動作を確実に行える耐久性の良い電気掃除機用吸込具を提供できるものである。
【００４３】
また、第１０の手段によれば、吸込具の円盤と吸込具本体下面との隙間に吸込具本体下面よりブラシ体を設け、そのブラシ体は円盤状の清掃用パッドに接するよう設定したことにより、塵埃が清掃用パッドの上面に付着した場合においてブラシ体により清掃用パッド上の塵埃をかきおとすことができるものであり、清掃用パッド上面をいつも清潔に保つことができ、使用者が使用中不快感を感じること無く清掃作業を行えるものであり、またブラシ体により清掃用パッドの回転軸中心部への塵埃の進入も防止でき、清潔で耐久性の良い電気掃除機用吸込具を提供できるものである。
【００４４】
また、第１１の手段によれば、吸込具の円盤と吸込具本体下面との隙間に吸込具本体下面よりブラシ体を設け、そのブラシ体は円盤状の清掃用パッドに接するよう設定し、ブラシ体を導電性の材質にて構成することにより清掃用パッドが被掃除面を移動したことにより発生する静電気を導電性のブラシ体を介して吸込具本体に伝えることができるものであり吸込具本体にアース構造を設けて清掃用中に発生する静電気をその都度アースし、塵埃が静電気により被掃除面に吸着されることのない、清掃効率のよい電気掃除機用吸込具を提供できるものである。
【００４５】
また、第１２の手段によれば、吸込具の吸込具下面にローラーを設けたことにより、吸込具を操作する場合において吸込具本体と被掃除面との平衡性が崩れ清掃用パッドの被掃除面との接地部が清掃用パッドの回転軸中心同士を結ぶ直線上よりズレることにより清掃用パッドの外周円接地部の接線が吸込具本体の進行角と異なとによる吸込具本体の操作不安定を防止できるものであり、清掃用パッドが均一に被掃除面に接するように吸込具本体と被掃除面との平衡性を保つことができ効率の良い高性能な電気掃除機用吸込具を提供できるものである。
【００４６】
第１３の手段においては、円盤が吸込具本体の左右および前後の外周縁部分のいずれかより突出していることで、円盤が壁際に当たった際には、円盤の床面側に設けた磨き布が壁際の隅部に当たり、隅部に溜まったホコリ等の塵挨を回転板が回転することで掻き出して、吸込口まで運び、吸塵させることで壁際隅掃除を行なうものである。
【００４７】
第１４の手段においては、円盤に下方開口の溝部を設けることで、被掃除面を掃除する際に、前記溝部があたかも吸込通路のにようになり、吸引風が円盤下面を流れるようになり、吸塵することができるものである。
【００４８】
第１５の手段においては、円盤をあたかも傘を開いたときのような錘形状にしたことにより、円盤下に設けた掃除用パッドと被掃除面との当節する部分の体積が従来の円盤と起毛布に比較して小さくなるため、より小さな操作力で吸込具本体を操作できるものである。
【００４９】
第１６の手段においては、円盤の外周縁部分に設けた複数の受け口が、吸込具本体の進行先にある大きな塵挨を回転しつつ捕らえて、吸込口まで運び込むため、より効率よく集塵できるものである。
【００５０】
第１７の手段においては、円盤を覆う構成をし、円盤とは別に自由に回転可能な回転カバーが、壁際の掃除の際に円盤より先に壁と接っするため、吸込具本体を操作すると回転カバーが操作方向に従って回転するため壁際での操作性が軽くなるものである。
【００５１】
第１８の手段においては、摩擦係数が高く、弾力性に富む材料で形成した空転防止タイヤを円盤の外周部に上下から挟み込むように巻き付けることで、吸込具本体を掃除すべく被掃除面に置いたとき、上下より挟み込んだ空転防止タイヤが円盤下面に出るため、被掃除面に当接し、摩擦係数の小さい滑り易い被掃除面上で回転板が空転すること無くスムーズに回転する。また、吸込具本体が壁に当たったときに回転板が当たるようにすれば、空転防止タイヤにはバンパーとしての効果があるため壁等の傷つけ防止をするものである。
【００５２】
第１９の手段においては、塵埃を吸引し集塵する電気掃除機の吸引側に連通され、着脱自在に接続される接続管を前記電気掃除機本体の吸引側に、上記第１〜第１８のいずれかの電気掃除機用吸込具が連通するよう着脱自在に接続されるものである。
【００５３】
【実施例】
以下本発明の第１の実施例について図１〜図６を用いて説明する。
【００５４】
図において、１は吸込具本体で、上部吸込具３、下部吸込具２を結合して構成されたものであり、結合部には吸込具本体１の外周に沿ってバンパー１４が構成されている。また、吸込具本体１の前方内部には下方開口を吸込口４とした吸込室１５が形成してある。この吸込室１５の中央は、吸込具本体１の後方で上部吸込具３、下部吸込具２に挟持された連通管１６、この連通管１６に回転自在に結合された接続管１７に連通し、かつ、この接続管１７には、電気掃除機（図示せず）の吸引側にホース（図示せず）を介して連通した延長管（図示せず）が着脱自在に接続される。
【００５５】
前記下部吸込具２内には軸受保持部１８が構成されており、軸受保持部１８内に設けられている軸受１９により回転軸２０が回転可能に設けられている。前記回転軸２０先端部には円盤１０が取付られており、円盤１０の下面には清掃用パッド２１が接着固定されている。２２は止め輪で、前記回転軸２０が前記軸受１９から抜けるのを防止している。前記軸受保持部１８は、前記円盤１０が被掃除面に対して傾斜すべく、前記軸受１９を保持している。また、前記円盤１０が前記吸込口４の左右近傍にもうけられており、円盤１０の傾斜方向を被掃除面との間隔が吸込口４近傍で狭く、前記吸込具本体１左右端近傍で広くなるよう構成している。
【００５６】
つぎに、この実施例に於ける動作、作用を説明する。
吸込具本体１を被掃除面に置いたとき、円盤１０は被掃除面に対して傾斜させて設けられているため、被掃除面との間隔が狭いＡ部に於いては接触圧が強いため清掃用パッド２１が撓み、被掃除面との間隔が広いＢ部に於いては清掃用パッド２１の先端部のみ被掃除面と接触する。
【００５７】
この状態で吸込具本体１を前方向に移動させたとき、Ａ部の清掃用パッド２１は一瞬停止状態となり基点の役割を果たす、従って円盤１０の中心部が前方へ作用すると同時に円盤１０に対して回転力を与えることになる、そして前記基点は、円盤１０端部を順次移動していき吸込具本体１の前移動に伴い円盤１０も回転することとなる。このとき円盤１０の回転中心に対して対称位置にある清掃用パッド２１は吸込具本体１の進行方向に対して、いわゆる筆ではき掃除をするが如く作用するものである。また吸込具本体１の後方に移動させた場合も同じ作用をするものである。
【００５８】
したがって、従来の吸込具のように起毛布を一体に取り付けたものに比べ吸込具本体１の前後操作の少ない回数で塵埃の掃き出し効果や拭き取り効果を充分に発揮できるものである。また吸込具本体１は回転可能な円盤１０を介して被掃除面と接触しており、吸込具本体１の前後方向の動きに対して円盤１０が回転し、吸込具本体１と被掃除面の間に発生する摩擦抵抗を軽減するため、軽い操作力で掃除作業が行えるものである。
【００５９】
また、吸込具本体１にて掃除作業を行ったとき、吸込具本体１の左右端にて清掃用パッド２１が被掃除面に対して高速の掃き出し動作を行い、清掃用パッド２１にて掃き出された塵埃を順次吸込口４に向かって掃き出し吸込通路２３を介して吸込口４より吸い込まれ、前記吸込具本体１の往復動作に対してより効率よく掃除作業が行えるものである。
【００６０】
また、第２の実施例では、図２に示すように、前記吸込具本体１の吸込口４と連通している吸込通路２３を下面側円盤１０の外周に沿って延設している。
【００６１】
つぎに、この実施例に於ける動作、作用を説明する。
清掃用パッド２１にて塵埃を掃き出す前に被掃除面に散乱している塵埃のなかで、吸込口４に流れる吸込風により吸引できる塵埃を清掃用パッド２１にて被掃除面に擦り付けるまえに吸込通路２３に流れる吸込風により、吸引してしまうものであるため、掃き掃除をしてから、拭く、磨くの工程に入る。例えば砂等の硬く、被掃除面を傷付ける塵埃を除去した後、清掃用パッド２１が拭く、磨くの作用を行うため、被掃除面を傷つけること無く掃除作業をおこなえるものであり、吸込通路２３が吸込具本体１の端部までのびているため、壁際に吸込具本体１が位置するとき吸込風を壁際まで影響させることができ壁際での吸込性能も確保できるものである。
【００６２】
また、第３の実施例では、図３に示すように、前記吸込具本体１の吸込通路２３を構成するため、吸込具本体１の前方面を塞ぐような板を設けて壁材２４として、前記壁材２４をゴム・塩ビ等の軟質材にて構成している。
【００６３】
つぎに、この実施例に於ける動作、作用を説明する。
前記吸込通路２３を形成する壁材２４を軟質材（ゴム、塩ビ等）で構成したことにより、吸込風を吸込具本体１の端部まで確実に影響させるために、壁材２４を被掃除面と接するほどの隙間関係にしたときでも、壁材２４は柔軟に変形することで被掃除面上に存在する例えば砂等の硬く被掃除面を傷付ける塵埃を壁材２４にてすり潰すことなく吸込通路２３に塵埃を誘い、吸引できるものである。また、前記のように吸込具本体１前方部と被掃除面の隙間関係することにより、吸引風が吸込具本体１前方部より漏れず、吸込通路２３の左右端部より吸引風が漏れることで吸込具本体１左右端部の集塵性能を向上できるため、吸込具本体１の全幅で掃除が可能になり効率よく清掃作業が行えるものである。
【００６４】
また、第４の実施例では、図４に示すように、前記吸込具本体１の吸込通路２３を構成する壁材２４のリブ体２５を、軟質材から成るバンパー１４により一体的に構成している。
【００６５】
つぎに、この実施例に於ける動作、作用を説明する。
前記リブ体２５を吸込具本体１の外周部に設けられているバンパー１４と一体成形することによりリブ体２５を吸込具本体１の外周最短部に設けることが出来るため、壁際近くに吸込口４が行くことができ、吸込口４からの強い吸引風が壁際の被掃除面にかかり、集塵できるためものである。また、部品点数も削減できるため、コスト削減ができ、より安価な電気掃除機用吸込具が提供できるものである。
【００６６】
また、第５の実施例では、図５に示すように、前記吸込具本体１の吸込通路２３の断面積を、吸込口４近傍では大きく吸込口４から遠ざかるに従い小さくなるように構成している。
【００６７】
つぎに、この実施例に於ける動作、作用を説明する。
被掃除面の塵埃を吸引すべく吸込具本体１下面の吸込口４に吸引風が流れたとき、に、吸引風は吸込口４付近で強く、吸込具本体１左右両端部に細長く設けられた吸込通路２３の左右端部に行くほど弱くなる。これは吸引風の密度が吸込口４を離れるにつれて薄くなるため、吸引風の流速が遅くなることで発生する問題であるが、本実施例の吸込通路２３では、吸込具本体１左右端部に行くほど吸込通路２３の断面積が小さくなるため、吸引風の密度は吸込具本体１左右端部に於いても薄くなることなく、一定の流速を得ることができるために吸込具本体１の全幅にて吸塵できるものである。これにより、吸込具本体１左右両端部において、塵埃を吸引できないため、清掃用パッド２１と被掃除面との間に塵埃を噛み込み、塵埃により被掃除面を傷つけたり、被掃除面に塵埃お擦り付けたりしなくなるものである。
【００６８】
また、第６の実施例によれば、図６に示すように、前記吸込具本体１の吸込通路２３の一部が吸込具本体１の内部を通るトンネル状に形成した連絡口２６を介し、吸込具本体１の端部に設けられた補助吸込口２７に連通している。
【００６９】
つぎに、この実施例に於ける動作、作用を説明する。
吸込口に吸引風を発生させ、この吸引風を吸込具本体１左右両端部にまで効率よく引き込むために、細長いトンネル状にした連絡口２６に吸引風を流す。吸引風が下方開口の吸込通路２３を流れる際、吸引風は突起物の多い被掃除面に衝突したり、下方開口のために吸込具本体１と被掃除面との間に出来た隙間より漏れたりして吸引風としての力を弱めてしまうが、滑らかな形状をしたトンネル状の連絡口２６を使うことにより、吸引風としての力を弱めることなく補助吸込口２７より吸引風を発生させ、吸込具本体１左右端部の塵埃を吸塵できるものである。
【００７０】
また、第７の実施例によれば、図７に示すように、前記吸込具本体１下面の長手方向幅において円盤状の清掃用パッド２１が被掃除面と接しない部分に固定起毛布２８を設け、清掃用パッド２１にて清掃されない部分を清掃できるよう設けている。
【００７１】
つぎに、この実施例に於ける動作、作用を説明する。
吸込具本体１が被掃除面上を移動するとき清掃用パッド２１の接している被掃除面は清掃用パッド２１にて清掃されるが吸込具本体１の中心部においては吸込口４を構成しているため清掃用パッド２１を設けることができず吸込風のみの清掃となってしまう。
【００７２】
よって前記吸込具本体１中心部にあたる被掃除面を清掃するため固定起毛布２８を設けることにより吸込具本体１の幅方向全てに於いて起毛布による清掃ができるものである。さらに清掃用パッド２１が均一に被掃除面に接するように吸込具本体１と被掃除面との平衡性を保つことができるものである。
【００７３】
また、第８の実施例によれば、図８に示すように、前記吸込具本体１下面と円盤１０にそれぞれリブ体２９，リブ体３０を設けており、そのリブ体２９，リブ体３０はそれぞれ摺動可能な状態にて接触するように設定されている。
【００７４】
つぎに、この実施例に於ける動作、作用を説明する。
前記リブ体２９、リブ体３０は摺動可能な状態にて接触するよう設けられているため、円盤１０の回転と共にリブ体３０が回転する。よって回転軸中心の軸受保持部１８への塵埃の進入を防止すると共に円盤１０に必要以上の付加が加わった場合にはリブ体２９、リブ体３０同士が圧接することにより軸受保持部１８に付加力を伝えることがないため軸受保持部１８の破壊を防止できるものであり円盤１０の動作を確実に行えるものである。
【００７５】
また、第９の実施例によれば、図１に示すように、前記吸込具本体１において円盤１０と下部吸込具２の下面との隙間を吸込口４の近傍に位置するほど大きくなるように設定している。
【００７６】
つぎに、この実施例に於ける動作、作用を説明する。
吸込具本体１外周部より進入しようとする塵埃は吸込具本体１外周部においての吸込具本体１下面と円盤１０との隙間より大きい塵埃は前記隙間に入り込むこと無く吸込通路２３より集塵され、前記隙間より小さい塵埃は前記隙間より進入するが前記隙間は吸込具本体１外周部より吸込口４に近ずくほど大きく設定されているため途中で係止することなく吸込口４に導かれ集塵されるものであり回転軸中心の軸受保持部１８への塵埃の進入を防止するものであり円盤１０の動作を確実に行えるものである。
【００７７】
また、第１０の実施例は図９に示すように、前記吸込具本体１の円盤１０と下部吸込具２下面との隙間に下部吸込具２下面よりブラシ体３１を設け、そのブラシ体３１は円盤１０に接するよう設定している。
【００７８】
つぎに、この実施例に於ける動作、作用を説明する。
塵埃が円盤１０の上面に付着した場合におい円盤１０が回転することによりブラシ体３１が円盤１０上の塵埃をかきおとすことができるものであり、円盤１０上面をいつも清潔に保つことができる。よって使用者が使用中不快感を感じること無く清掃作業を行えるものであり、またブラシ体３１により円盤１０の回転軸中心部の軸受保持部１８への塵埃の進入も防止できるものである。
【００７９】
また、第１１の実施例も図９に示すように、前記下部吸込具２下面と円盤１０との隙間に下部吸込具２下面よりブラシ体３１を設け、そのブラシ体３１は円盤１０に接っするよう設定し、ブラシ体３１を導電性の材質にて構成している。
【００８０】
つぎに、この実施例に於ける動作、作用を説明する。
円盤１０が被掃除面を移動したことにより発生する静電気を導電性のブラシ体３１を介して吸込具本体１に伝えることができるものであり吸込具本体１にアース構造を設けて清掃用中に発生する静電気をその都度アースし、塵埃が静電気により被掃除面に吸着されることのないように吸込具本体１の移動により都度静電気をアースし塵埃を集塵しやすくするものである。
【００８１】
また、第１２の実施例は図１０に示すように、前記吸込具本体１の下部吸込具２下面にローラー３２を設けている。
【００８２】
つぎに、この実施例に於ける動作、作用を説明する。
吸込具本体１を操作する場合において円盤１０がそれぞれ傾斜して設けられているため吸込具本体１と被掃除面との平衡性が崩れ円盤１０と被掃除面との接地部が円盤１０の回転軸中心同士を結ぶ直線上よりズレると円盤１０の外周円接地部３３の接線が吸込具本体１の進行角と異なるため吸込具本体１の進行方向が作業者の思う方向と異なるが、ローラー３２が被掃除面に接しているため作業者の操作時の力がローラー３２に伝わり吸込具本体１の進行方向を吸込具本体１前後方向に矯正し操作不安定を防止できるものでありる。また、円盤１０の下面の清掃用パッド２１が均一に被掃除面に接するように吸込具本体１と被掃除面との平衡性を保つことができるものである。
【００８３】
また、第１３の実施例を図１１と共に説明する。円盤１０の外周部を吸込具本体１の前後・左右いづれかの外周縁部分より外側に出るように円盤１０を設ける。すなわち、図１１の(b)〜(h)に示すように円盤２０を吸込具本体１に取り付けている。同図(a)は円盤１０が吸込具本体１の外周からはみ出さないように取り付けたもので、また、図中の一点鎖線は壁などの障害物、段差などを示す。
【００８４】
つぎに、この実施例における動作、作用を説明する。
壁際（前・左右）掃除の際に、円盤１０の外周部が吸込具本体１の外周縁部分より出ていれば、まず円盤１０が壁に当たり、円盤１０に軟質材を使用していれば吸込具本体１が直接衝突するときより衝撃を和らげ、バンパー効果をもたらす。また、吸込具本体１を壁に沿って左右に動作させたとき、円盤１０が壁に沿って回転することが可能なために、壁際における操作が楽になる。
【００８５】
円盤１０が吸込具本体１の外周縁部分の後ろから出ていれば、吸込具本体１を操作した勢いで、敷居などの低い段差があるところに吸込具本体１が衝突しても、まず円盤１０があたるので、円盤１０に軟質材を使用していれば、前述同様のバンパー効果を得ることができる。
【００８６】
さらに、吸込具本体１が入り難い狭い隙間において、円盤１０が隙間に入り込み、円盤１０が回転して塵埃を手前に掃き出し、より塵埃を集塵しやすくなるものである。
【００８７】
また、本発明の第１４の実施例を図１２と共に説明する。
円盤１０の床面方向に掃除用パッド２１を設け、掃除用パッド２１に下方開口で円盤１０および掃除用パッド２１の回転中心を通り、直角に交わり、円盤１０外周部に到達する十文字状に形成した溝部３４を設けたものである。
【００８８】
次に、上記構成における動作、作用を説明する。床面を掃除すべく吸込具本体１を被掃除面に設置させ、前後に操作しながら塵埃を集塵すべく吸引を掛けると、吸込口４内に吸引風が発生し、円盤１０外周部の溝部３４開口部が吸込口４付近を通過すると、溝部３４に吸引風が流れ、円盤１０下面の塵挨を吸引するものである。
【００８９】
また、本発明の第１５の実施例を図１３と共に説明する。
円盤１０と掃除用パッド２１もろとも中心を上方に引っ張り上げるようにして円盤１０をあたかも傘を開いたときのような略円錘状の形状になるように構成したものである。
【００９０】
次に、上記構成における動作、作用を説明する。吸込具本体１を被掃除面に置いて掃除すべく床面に押し付けたとき、円盤１０は図１３のようになり、Ｅ部は被掃除面に押し付けられたときに接触する部分である。このＥ部の体積が吸込具本体１と被掃除面との間に発生する操作抵抗に関係する。つまり、前記体積が小さいほど、被掃除面に触れる部分が小さくなるために操作するときの抵抗が小さくなる。FLは被掃除面、Ｆは略円錐上のへこみ部分を示す。
【００９１】
そこで、図１４に示してある従来の円盤と本発明の円盤１０の被掃除面における接触体積を比較する。まず、図１４にて従来の円盤の接触体積は次の式で示される。
【００９２】
（掃除用パッドの全体体積）＝π×（ｒ×ｒ）×ｈ
接触体積は、掃除用パッド（起毛布１２）全体の半分であるから、
（従来の接触体積）＝（π×（ｒ×ｒ）×ｈ）÷２
次に、図１４から本発明の円盤１０の接触体積を式で示す。錘状のへこみを考慮しないときの掃除用パッド２１の全体体積および接触体積は前記のものと同じである。これから錘状の体積を差し引けば本発明の接触体積が求められる。
【００９３】

以上から、本発明の接触体積が従来の接触体積にくらべ、掃除用パッド２１が被掃除面に当たる体積が３分の１と小さくなっていることがわかる。
【００９４】
したがって、掃除用パッド２１の被掃除面に対する当たりが小さくなったことで、操作性が軽くなり、より快適に掃除ができるものである。
【００９５】
以下、本発明の第１６の実施例を図１５と共に説明する。すなわち、円盤１０外周縁部分に複数の受け口３５を設けた。
【００９６】
次に、上記構成に於ける動作、作用を説明する。床面を掃除すべく吸込具本体１を前進させた際、極めて大きな塵挨があったとき、円盤１０外周部に複数の切れ込みを設け、受け口３５を形成する。複数の受け口３５の何れかに塵挨が納まり、円盤１０が回転することで吸込口４まで運搬されて吸引される。これにより、粉体状や繊維状の塵挨のほかに、集塵しずらかった固形状の塵挨も吸引でき、掃除性が向上するものである。
【００９７】
以下、本発明の第１７の実施例を図１６と共に説明する。すなわち、円盤１０の外周縁部分から上方にかぶさるように設けれ、円盤１０と非連動で自由に回転できる回転カバー３６を構成しているものである。
次に、上記構成における動作、作用を説明する。壁の際を掃除する際に、回転カバー３６を当てて操作すると、回転カバー３６は円盤１０と非連動で動作するために、吸込具本体１の操作方向と円盤１０の回転方向が逆であったり、円盤１０に回転ムラが発生しても、回転カバー３６は非連動で回転するため、壁際においてスムーズに回転して、壁際での操作を補助する。
【００９８】
したがって、回転カバー３６が壁際でタイヤのような役割をするため、吸込具本体１を壁際に押し付けながら横に操作しても、スムーズに回転し、より操作しやすくなるものである。
【００９９】
以下に、本発明の第１８の実施例を図１７と共に説明する。すなわち、円盤１０外周縁部分に上下から挟み込み、外周部を巻くようにして空転防止タイヤ３７を設けた。空転防止タイヤ３７は、摩擦係数が高く、弾力性に富む材料で構成しており、また、空転防止タイヤ３７の上面全周には、凹状部３８と凸状部３９が交互に設けられている。
【０１００】
次に、上記構成における動作、作用を説明する。空転防止タイヤ３７が被掃除面に接触することにより、掃除用パッド２１が接触するより大きな摩擦抵抗が発生し、より大きな力で基点が被掃除面に固定するために確実に回転動作する。
【０１０１】
これにより、多くの被掃除面において、円盤１０および掃除用パッド２１の効力を発揮することができるため、より広い範囲の被掃除面に対しての掃除性が高まった。
【０１０２】
なお、円盤１０を本発明の第１２の実施例のように構成すれば、空転防止タイヤは弾性に富む材料で構成されているためにバンパに構成すれば、空転防止タイヤ３７は弾性に富む材料で構成されているためにバンパーとしての効果が得られるものである。
【０１０３】
【発明の効果】
以上の説明したように、本発明の第１の手段によれば、電気掃除機用吸込具は木床上や畳上を掃除する場合に於いて、被掃除面に対して傾斜のある回転可能な円盤を設けたことにより、円盤下面に設けた清掃用パッドにて被掃除面を速く擦ることができるため被掃除面に対する掃き出し効果を充分に発揮できる。そして円盤が吸込口の左右近傍に設けられているため、清掃用パッドで掃き出された塵埃を即座に吸い込むことができ、また、じゅうたん上を掃除する場合に於いては、円盤が回転するため吸込具本体と被掃除面の摩擦抵抗を軽減することにより軽い操作力で掃除作業を行うことができ、操作性がよく、耐久性のある、使い勝手の良い電気掃除機用吸込具を提供できる。

【０１０８】
また、第６の手段によれば、吸込具の吸込通路の一部が吸込具本体の内部を通るトンネル状に形成した連絡口を介した補助吸込口を有することにより、吸込風の圧力、風速をトンネル内にて保持し補助吸込口にて吸込具本体端部より被掃除面の塵埃を効率良く集塵出来る、高性能な電気掃除機用吸込具を提供できるものである。
【０１０９】
また、第７の手段によれば、吸込具本体の幅において円盤状の清掃用パッドが接しない部分に位置させたことにより、固定起毛布が清掃用パッドにて清掃されない部分を清掃するものであり、さらに清掃用パッドが均一に被掃除面に接するように吸込具本体と被掃除面との平衡性を保つことができるもので吸込具本体の幅全てを清掃することができる効率の良い高性能な電気掃除機用吸込具を提供できるものである。
【０１１０】
また、第８の手段によれば、吸込具本体下面と円盤状の清掃用パッドにそれぞれリブ体を設けたことにより、またそのリブ体はそれぞれ摺動可能な状態にて接触しているため回転軸中心への塵埃の進入を防止すると共に円盤に必要以上の付加が加わった場合にはリブ体同士が圧接することにより回転軸に付加力を伝えることがないため回転軸の破壊を防止できるものであり回転板の動作を確実に行える耐久性の良い電気掃除機用吸込具を提供できるものである。
【０１１１】
また、第９の手段によれば、円盤状の清掃用パッドと吸込具本体下面との隙間を吸込口の近傍に位置するほど大きくなるように設定したことにより、吸込具外周部より進入しようとする塵埃は吸込具外周部においての吸込具本体下面と清掃用パッドとの隙間より大きい塵埃は前記隙間に入り込むこと無く吸込通路より集塵され、前記隙間より小さい塵埃は前記隙間より進入するが前記隙間は吸込具外周部より吸込口に近ずくほど大きく設定されているため途中で係止することなく吸込口に導かれ集塵されるものであり回転軸中心への塵埃の進入を防止するものであり回転板の動作を確実に行える耐久性の良い電気掃除機用吸込具を提供できるものである。
【０１１２】
また、第１０の手段によれば、円盤と吸込具本体下面との隙間に吸込具本体下面よりブラシ体を設け前記ブラシ体は円盤状の清掃用パッドに接っするよう設定したことにより、塵埃が清掃用パッドの上面に付着した場合においてブラシ体により清掃用パッド上の塵埃をかきおとすことができるものであり、清掃用パッド上面をいつも清潔に保つことができ、使用者が使用中不快感を感じること無く清掃作業を行えるものであり、またブラシ体により清掃用パッドの回転軸中心部への塵埃の進入も防止でき、清潔で耐久性の良い電気掃除機用吸込具を提供できるものである。
【０１１３】
また、第１１の手段によれば、円盤と吸込具本体下面との隙間に吸込具本体下面よりブラシ体を設け、前記ブラシ体は円盤状の清掃用パッドに接っするよう設定し、ブラシ体を導電性の材質にて構成することにより、清掃用パッドが被掃除面を移動した時に発生する静電気を導電性のブラシ体を介して吸込具本体に伝えることができるものであり吸込具本体にアース構造を設けて清掃用中に発生する静電気をその都度アースし、塵埃が静電気により被掃除面に吸着されることのない、清掃効率のよい電気掃除機用吸込具を提供できるものである。

【０１１６】
また、第１４の手段によれば、円盤の床面と当節する面に、円盤回転中心から放射状に円盤外周縁部分に伸びる、下方開口の溝部を設けたことにより、円盤下に吸引風が流れることで、円盤下の塵埃も効率よく集塵され、掃除性を向上させた電気掃除機用吸込具を提供できるものである。
【０１１７】
また、第１５の手段によれば、円盤をあたかも傘を開いたときのような錘形状にしたことにより、吸込具本体を被掃除面に置いたときの掃除用パッドの被掃除面に強く接触する体積が小さくなり、操作性が軽くなる電気掃除機用吸込具を提供できるものである。

また、第１８の手段によれば、摩擦係数が高く、軟質材料でできた空転防止タイヤを円盤外周縁部分に上下から挟み込むように固定し、巻き付けた構成をしたために、空転防止タイヤの円盤下面から突出した部分が被掃除面に当接するため、摩擦係数の低い被掃除面においても円盤が良く回転し、磨き性が向上する。なお、段差および壁に当てたとき空転防止タイヤがまず先に当たるように構成すればバンパーとしての効果が得られ、傷つけ防止となる。
【０１２１】
以上により、掃除性が向上して快適に掃除できる電気掃除機用吸込具並びにそれを連通させた電気掃除機が提供できる。

[0032]
[Action]
According to the first means, the rotatable disk having the cleaning pad on the lower surface is provided in a state inclined with respect to the surface to be cleaned. The cleaning pad located farthest from the lower surface of the suction tool on the outer periphery comes into contact with the surface to be cleaned, and when the suction tool is moved forward, the contact point with the surface to be cleaned becomes the base point and the center of the disk moves forward At the same time, a rotational force is applied to the disk, and the base point sequentially moves along the end of the disk, and the disk rotates as the suction tool moves forward.
[0033]
At this time, the cleaning pad in a symmetrical position with respect to the rotation center of the disk rotates in the same direction with respect to the advancing direction of the suction tool, and the cleaning pad performs so-called scrubbing cleaning with respect to the surface to be cleaned. It works as it is. Therefore, compared with a conventional suction tool in which a raised cloth is integrally attached, the dust discharge effect and the wiping effect can be sufficiently exerted with less number of operations of the suction tool. Further, since the frictional force with the surface to be cleaned is reduced by the rotation of the disk, the operation resistance associated with the front / rear operation of the suction tool is reduced, and the cleaning operation can be performed with a lighter operation.
[0034]
And because the disc and the cleaning pad are provided in the vicinity of the left and right of the suction port, and the interval between the outer periphery of the disk and the surface to be cleaned is narrow in the vicinity of the suction port, and is inclined in the direction of widening at the left and right ends of the suction tool body, The cleaning pad sweeps the surface to be cleaned toward the suction port, wipes and polishes the dust, and the dust swept to the suction port is quickly and reliably sucked in, so the cleaning work can be performed more effectively. .
[0035]
Further, according to the second means, among the dust scattered on the surface to be cleaned before the dust is swept out by the cleaning pad, the dust that can be sucked by the suction air flowing through the suction port is collected by the cleaning pad. Since it is sucked by the suction air flowing in the suction passage before rubbing against the surface to be cleaned, it enters the process of wiping and polishing after sweeping and cleaning, for example, sand etc. is hard and scratches the surface to be cleaned After sucking such dust, it is wiped with a cleaning pad and polished, so it can be cleaned without damaging the surface to be cleaned, and the suction passage extends to the end of the suction tool body When the suction tool main body is located near the wall, the suction air can be influenced to the wall side, and the suction performance at the wall side can be ensured.
[0036]
According to the third means, since the rib body forming the suction passage is made of a soft material (for example, rubber, vinyl chloride), the rib body is used to reliably influence the suction air to the end of the suction tool body. When setting the positional gap relationship to contact the surface to be cleaned, the pressure of the suction air and the wind speed to remove dust that is hard to damage the surface to be cleaned, such as sand, etc. The suction air can be affected to the end of the suction tool body without damaging the surface to be cleaned, and the suction performance of the entire width of the suction tool body can be secured. is there.
[0037]
Further, according to the fourth means, the rib body can be provided at the shortest outer peripheral portion of the suction tool body by integrally molding the rib body with the bumper member provided at the outer peripheral part of the suction tool body. In addition, the suction air can be affected to the wall, and the number of parts can be reduced, so that an inexpensive and high-performance vacuum cleaner suction tool can be provided.
[0038]
Further, according to the fifth means, by gradually reducing the cross-sectional area of the suction passage from the vicinity of the suction port toward the end of the suction tool main body, the distance between the disk outer peripheral portion and the surface to be cleaned is near the suction port. Dust swept away from the suction port while generating the action of sweeping, wiping, and polishing the cleaning pad toward the suction port because it was tilted in a direction that became narrow at the left and right ends of the suction tool body. The suction air pressure and air velocity required to quickly and reliably suck the air are the same as the vicinity of the suction port at the end of the suction tool body where the distance between the cleaning pad on the underside of the disk and the surface to be cleaned is equal to or greater than the vicinity of the suction port. To obtain the suction air pressure and speed, the amount of suction air slightly larger than the amount of suction air flowing in through the gap between the cleaning pad and the surface to be cleaned is reduced from the amount of suction air in the suction passage. Because it has a cross-sectional area in the suction passage that can, The pressure and speed of the suction air between the suction passages are the same or higher near the suction port and at the end of the suction tool body, and the suction air can flow between the cleaning pad and the surface to be cleaned. Dust removed with the cleaning pad is quickly guided to the suction port together with the suction air without being rubbed against the surface to be cleaned with the cleaning pad, providing a high-performance vacuum cleaner suction tool. It can be done.
[0039]
Further, according to the sixth means, the auxiliary suction port provided at the end of the suction tool body is connected to the suction tool body through a communication port formed in a tunnel shape in which a part of the suction passage of the suction tool passes through the inside of the suction tool body. By having a high-performance vacuum cleaner suction tool that can maintain the pressure and speed of the suction air in the tunnel and efficiently collect dust from the end of the suction tool body at the auxiliary suction port. It can be provided.
[0040]
Further, according to the seventh means, the fixed raising cloth positioned in the portion where the disc-shaped cleaning pad does not contact in the width of the suction tool main body cleans the portion that is not cleaned by the cleaning pad, Efficient and high-performance electricity that can maintain the balance between the suction tool body and the surface to be cleaned so that the cleaning pad contacts the surface to be cleaned evenly and can clean the entire width of the suction tool body A vacuum cleaner suction tool can be provided.
[0041]
According to the eighth means, the rib body is provided on the lower surface of the suction tool main body and the disc-shaped cleaning pad, and the rib bodies are in contact with each other in a slidable state. In addition to preventing dust from entering the disk and adding more than necessary to the disk, the ribs are pressed against each other so that no additional force is transmitted to the rotating shaft, thus preventing the rotating shaft from being destroyed. It is possible to provide a vacuum cleaner suction tool that can reliably operate the rotary plate.
[0042]
Further, according to the ninth means, the suction tool outer peripheral portion is set so that the gap between the disc-shaped cleaning pad and the lower surface of the suction tool main body becomes larger in the vicinity of the suction port in the suction tool main body. Dust that is about to enter more than the gap between the lower surface of the suction tool body and the cleaning pad at the outer periphery of the suction tool is collected from the suction passage without entering the gap, and dust smaller than the gap is collected from the gap. However, since the gap is set to be larger as it is closer to the suction port than the outer peripheral part of the suction tool, dust is introduced to the suction port without being locked in the middle, and dust enters the center of the rotating shaft. Therefore, it is possible to provide a durable vacuum cleaner suction tool capable of reliably operating the rotating plate.
[0043]
Further, according to the tenth means, the brush body is provided from the lower surface of the suction tool body in the gap between the disk of the suction tool and the lower surface of the suction tool body, and the brush body is set so as to be in contact with the disk-shaped cleaning pad. When the dust adheres to the upper surface of the cleaning pad, the brush body can wipe off the dust on the cleaning pad, and the upper surface of the cleaning pad can be kept clean at all times. The cleaning work can be performed without feeling uncomfortable, and the brush body can prevent dust from entering the center of the rotating shaft of the cleaning pad, thereby providing a clean and durable vacuum cleaner suction tool. Is.
[0044]
Further, according to the eleventh means, the brush body is provided from the lower surface of the suction tool body in the gap between the disk of the suction tool and the lower surface of the suction tool body, and the brush body is set so as to be in contact with the disk-shaped cleaning pad. By constructing the body with a conductive material, the static electricity generated when the cleaning pad moves on the surface to be cleaned can be transmitted to the suction tool body through the conductive brush body. A grounding structure is provided to ground static electricity generated during cleaning, and a vacuum cleaner suction tool with high cleaning efficiency can be provided in which dust is not attracted to the surface to be cleaned by static electricity. .
[0045]
Further, according to the twelfth means, by providing the roller on the lower surface of the suction tool, the balance between the suction tool body and the surface to be cleaned is lost when the suction tool is operated, and the cleaning pad is cleaned. Operation of the suction tool main body is unstable due to the tangent of the outer peripheral circular grounding part of the cleaning pad being different from the advance angle of the suction tool main body because the ground contact part with the surface deviates from the straight line connecting the rotation shaft centers of the cleaning pad. Provides a highly efficient and efficient vacuum cleaner suction tool that can maintain the balance between the suction tool body and the surface to be cleaned so that the cleaning pad contacts the surface to be cleaned uniformly. It can be done.
[0046]
In the thirteenth means, the disc protrudes from either the left or right and front and rear outer peripheral edges of the suction tool body, so that when the disc hits the wall, a polishing cloth provided on the floor side of the disc , Hits the corner of the wall, dust such as dust accumulated in the corner is scraped out by rotating the rotating plate, transported to the suction port, and dust is absorbed, and the corner of the wall is cleaned.
[0047]
In the fourteenth means, by providing a groove portion with a lower opening in the disk, when cleaning the surface to be cleaned, the groove portion looks like a suction passage, and the suction air flows through the lower surface of the disk. It can absorb dust.
[0048]
In the fifteenth means, since the disk is shaped like a weight as when an umbrella is opened, the volume of the portion where the cleaning pad provided under the disk and the surface to be cleaned are in contact with the conventional disk Since it becomes smaller than a raised cloth, the suction tool body can be operated with a smaller operating force.
[0049]
In the sixteenth means, the plurality of receiving ports provided on the outer peripheral edge portion of the disk capture and rotate the large dust existing at the destination of the suction tool body while carrying it to the suction port, so that dust can be collected more efficiently. Is.
[0050]
In the seventeenth means, the rotating cover that is configured to cover the disk and can be freely rotated separately from the disk comes into contact with the wall before the disk when cleaning the wall. Since the rotating cover rotates in accordance with the operation direction, the operability at the wall becomes light.
[0051]
18th meansInIn this case, when the anti-spinning tire formed of a material having a high friction coefficient and having high elasticity is wound around the outer periphery of the disk so as to be sandwiched from above and below, when the suction tool body is placed on the surface to be cleaned, Since the anti-slip tire sandwiched from above and below comes out on the lower surface of the disk, it comes into contact with the surface to be cleaned, and the rotating plate rotates smoothly on the slippery surface to be cleaned with a small friction coefficient without slipping. Further, if the rotating plate hits when the suction tool main body hits the wall, the anti-spinning tire has an effect as a bumper and prevents damage to the wall or the like.
[0052]
In a nineteenth means, a connecting pipe connected to a suction side of a vacuum cleaner that sucks and collects dust and is detachably connected to the suction side of the main body of the vacuum cleaner, the first to eighteenth means. Any of the vacuum cleaner suction tools are detachably connected so as to communicate with each other.
[0053]
【Example】
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
[0054]
In the figure, reference numeral 1 denotes a suction tool main body, which is configured by combining an upper suction tool 3 and a lower suction tool 2, and a bumper 14 is configured along the outer periphery of the suction tool main body 1 at the coupling portion. . A suction chamber 15 having a lower opening as a suction port 4 is formed in the front inside of the suction tool body 1. The center of the suction chamber 15 communicates with the upper suction tool 3 at the rear of the suction tool body 1, the communication pipe 16 sandwiched between the lower suction tools 2, and the connection pipe 17 that is rotatably coupled to the communication pipe 16. In addition, an extension pipe (not shown) communicating with a suction side of a vacuum cleaner (not shown) via a hose (not shown) is detachably connected to the connection pipe 17.
[0055]
A bearing holding portion 18 is configured in the lower suction tool 2, and a rotary shaft 20 is rotatably provided by a bearing 19 provided in the bearing holding portion 18. A disk 10 is attached to the tip of the rotary shaft 20, and a cleaning pad 21 is bonded and fixed to the lower surface of the disk 10. A retaining ring 22 prevents the rotary shaft 20 from coming off the bearing 19. The bearing holding portion 18 holds the bearing 19 so that the disk 10 is inclined with respect to the surface to be cleaned. Further, the disk 10 is provided in the vicinity of the left and right of the suction port 4, and the interval between the inclined direction of the disk 10 and the surface to be cleaned is narrow in the vicinity of the suction port 4 and wide in the vicinity of the left and right ends of the suction tool body 1. It is configured as follows.
[0056]
Next, the operation and action in this embodiment will be described.
When the suction tool main body 1 is placed on the surface to be cleaned, the disk 10 is inclined with respect to the surface to be cleaned, and the contact pressure is strong at the portion A where the distance from the surface to be cleaned is narrow. The cleaning pad 21 bends, and only the tip of the cleaning pad 21 is in contact with the surface to be cleaned at the B portion where the space between the cleaning pad 21 and the surface to be cleaned is wide.
[0057]
When the suction tool main body 1 is moved forward in this state, the cleaning pad 21 of the A part is stopped for a moment and serves as a base point. Therefore, the central part of the disk 10 acts forward and simultaneously with respect to the disk 10. Then, the rotational force is applied, and the base point sequentially moves at the end of the disk 10 and the disk 10 also rotates as the suction tool body 1 moves forward. At this time, the cleaning pad 21 in a symmetric position with respect to the center of rotation of the disk 10 acts as if it is a so-called brush scrubbing with respect to the advancing direction of the suction tool body 1. Further, the same effect is obtained when the suction tool body 1 is moved rearward.
[0058]
Therefore, the dust sweeping effect and the wiping effect can be sufficiently exhibited with a small number of operations of the suction tool main body 1 in the front-rear operation compared to the conventional suction tool in which the raised cloth is integrally attached. Further, the suction tool body 1 is in contact with the surface to be cleaned via a rotatable disk 10, and the disk 10 rotates with respect to the movement of the suction tool body 1 in the front-rear direction, so that the suction tool body 1 and the surface to be cleaned are in contact with each other. In order to reduce the frictional resistance generated between them, the cleaning operation can be performed with a light operating force.
[0059]
Further, when cleaning is performed with the suction tool body 1, the cleaning pad 21 performs a high-speed sweeping operation with respect to the surface to be cleaned at the left and right ends of the suction tool body 1, and the cleaning pad 21 performs the cleaning operation. The discharged dust is sequentially swept out toward the suction port 4 and sucked from the suction port 4 through the suction passage 23, so that the cleaning operation can be performed more efficiently with respect to the reciprocating operation of the suction tool body 1.
[0060]
In the second embodiment, as shown in FIG. 2, a suction passage 23 communicating with the suction port 4 of the suction tool main body 1 is extended along the outer periphery of the lower surface side disk 10.
[0061]
Next, the operation and action in this embodiment will be described.
The dust that can be sucked by the suction air flowing through the suction port 4 among the dust scattered on the surface to be cleaned before the dust is swept away by the cleaning pad 21 is sucked before being rubbed against the surface to be cleaned by the cleaning pad 21. Since the air is sucked by the suction air flowing in the passage 23, the process starts with wiping and polishing after sweeping and cleaning. For example, after removing dust that is hard and scratches the surface to be cleaned, such as sand, the cleaning pad 21 wipes and polishes, so that the cleaning operation can be performed without damaging the surface to be cleaned. Since it extends to the end of the suction tool body 1, when the suction tool body 1 is located near the wall, the suction air can be influenced to the wall side, and the suction performance at the wall side can be ensured.
[0062]
Further, in the third embodiment, as shown in FIG. 3, in order to configure the suction passage 23 of the suction tool main body 1, a plate that closes the front surface of the suction tool main body 1 is provided as a wall member 24. The wall member 24 is made of a soft material such as rubber or vinyl chloride.
[0063]
Next, the operation and action in this embodiment will be described.
Since the wall member 24 forming the suction passage 23 is made of a soft material (rubber, polyvinyl chloride, etc.), the wall member 24 is cleaned by the surface to be cleaned in order to reliably influence the suction air to the end of the suction tool body 1. Even when the gap is in contact with the wall material 24, the wall material 24 is deformed flexibly so that the wall material 24 sucks dust such as sand that hardly damages the surface to be cleaned without being crushed by the wall material 24. Dust can be attracted and sucked into the passage 23. Further, as described above, the suction air does not leak from the front part of the suction tool main body 1 and the suction air leaks from the left and right end parts of the suction passage 23 because of the clearance relation between the front part of the suction tool main body 1 and the surface to be cleaned. Since the dust collection performance at the left and right end portions of the suction tool main body 1 can be improved, cleaning can be performed with the full width of the suction tool main body 1, and the cleaning work can be performed efficiently.
[0064]
Further, in the fourth embodiment, as shown in FIG. 4, the rib body 25 of the wall member 24 constituting the suction passage 23 of the suction tool body 1 is integrally formed by the bumper 14 made of a soft material. Yes.
[0065]
Next, the operation and action in this embodiment will be described.
Since the rib body 25 can be provided at the shortest outer periphery of the suction tool body 1 by integrally molding the rib body 25 with the bumper 14 provided at the outer periphery of the suction tool body 1, the suction port 4 is located near the wall. This is because a strong suction wind from the suction port 4 is applied to the surface to be cleaned near the wall and can collect dust. Moreover, since the number of parts can also be reduced, cost can be reduced and a cheaper vacuum cleaner suction tool can be provided.
[0066]
Further, in the fifth embodiment, as shown in FIG. 5, the cross-sectional area of the suction passage 23 of the suction tool main body 1 is configured to be large in the vicinity of the suction port 4 and become smaller as the distance from the suction port 4 increases. .
[0067]
Next, the operation and action in this embodiment will be described.
When the suction air flows into the suction port 4 on the lower surface of the suction tool body 1 to suck the dust on the surface to be cleaned, the suction wind is strong near the suction port 4 and is elongated at the left and right ends of the suction tool body 1. It becomes weaker as it goes to the left and right ends of the suction passage 23. This is a problem that occurs because the suction air density decreases as it moves away from the suction port 4, and the suction air flow rate becomes slow. However, in the suction passage 23 of the present embodiment, the suction tool body 1 is located at the left and right ends. Since the cross-sectional area of the suction passage 23 decreases as it goes, the density of the suction air does not decrease even at the left and right ends of the suction tool body 1, and a constant flow rate can be obtained. Can absorb the dust. As a result, dust cannot be sucked at the left and right ends of the suction tool main body 1, so that the dust is caught between the cleaning pad 21 and the surface to be cleaned, and the surface to be cleaned is damaged by the dust, or dust is applied to the surface to be cleaned. It will not rub.
[0068]
Further, according to the sixth embodiment, as shown in FIG. 6, a part of the suction passage 23 of the suction tool body 1 is formed through a communication port 26 formed in a tunnel shape passing through the inside of the suction tool body 1, It communicates with an auxiliary suction port 27 provided at the end of the suction tool body 1.
[0069]
Next, the operation and action in this embodiment will be described.
Suction air is generated at the suction port, and in order to efficiently draw the suction air to the left and right ends of the suction tool body 1, the suction air is caused to flow through the connection port 26 that is formed in a long and narrow tunnel shape. When the suction air flows through the suction passage 23 of the lower opening, the suction air collides with the surface to be cleaned with many protrusions or leaks from the gap formed between the suction tool body 1 and the surface to be cleaned due to the lower opening. However, by using the tunnel-shaped connection port 26 having a smooth shape, the suction air is generated from the auxiliary suction port 27 without weakening the force as the suction air. The suction tool main body 1 can absorb dust at the left and right ends.
[0070]
Further, according to the seventh embodiment, as shown in FIG. 7, the fixed raising cloth 28 is attached to the portion where the disc-shaped cleaning pad 21 does not contact the surface to be cleaned in the longitudinal width of the lower surface of the suction tool body 1. It is provided so that a portion not cleaned by the cleaning pad 21 can be cleaned.
[0071]
Next, the operation and action in this embodiment will be described.
When the suction tool main body 1 moves on the surface to be cleaned, the surface to be cleaned which is in contact with the cleaning pad 21 is cleaned by the cleaning pad 21, but the suction port 4 is formed at the center of the suction tool main body 1. Therefore, the cleaning pad 21 cannot be provided, and only the suction air is cleaned.
[0072]
Therefore, by providing the fixed raising cloth 28 to clean the surface to be cleaned corresponding to the central part of the suction tool body 1, cleaning with the raising cloth can be performed in all the width directions of the suction tool body 1. Furthermore, the balance between the suction tool body 1 and the surface to be cleaned can be maintained so that the cleaning pad 21 is in contact with the surface to be cleaned uniformly.
[0073]
Further, according to the eighth embodiment, as shown in FIG. 8, the rib body 29 and the rib body 30 are provided on the lower surface of the suction tool main body 1 and the disk 10, respectively. Each is set to contact in a slidable state.
[0074]
Next, the operation and action in this embodiment will be described.
Since the rib body 29 and the rib body 30 are provided so as to contact in a slidable state, the rib body 30 rotates with the rotation of the disk 10. Accordingly, dust is prevented from entering the bearing holding portion 18 at the center of the rotating shaft, and when the disc 10 is added more than necessary, the rib body 29 and the rib body 30 are pressed against each other to be added to the bearing holding portion 18. Since the force is not transmitted, the bearing holding portion 18 can be prevented from being broken, and the disk 10 can be reliably operated.
[0075]
Further, according to the ninth embodiment, as shown in FIG. 1, in the suction tool main body 1, the gap between the disk 10 and the lower surface of the lower suction tool 2 is increased as it is located near the suction port 4. It is set.
[0076]
Next, the operation and action in this embodiment will be described.
Dust that is about to enter from the outer periphery of the suction tool body 1 is collected from the suction passage 23 without entering the gap, and dust that is larger than the gap between the lower surface of the suction tool body 1 and the disk 10 at the outer periphery of the suction tool body 1 Dust smaller than the gap enters from the gap, but the gap is set to be larger from the outer peripheral portion of the suction tool main body 1 to the suction port 4 and is therefore guided to the suction port 4 without being stopped halfway. This prevents dust from entering the bearing holding portion 18 at the center of the rotating shaft, and the operation of the disk 10 can be performed reliably.
[0077]
In the tenth embodiment, as shown in FIG. 9, a brush body 31 is provided from the lower surface of the lower suction tool 2 in the gap between the disk 10 of the suction tool body 1 and the lower surface of the lower suction tool 2. It is set so as to contact the disk 10.
[0078]
Next, the operation and action in this embodiment will be described.
When the dust adheres to the upper surface of the disk 10, the brush body 31 can scrape off the dust on the disk 10 by rotating the disk 10, and the upper surface of the disk 10 can always be kept clean. Therefore, the user can perform cleaning without feeling uncomfortable during use, and the brush body 31 can prevent dust from entering the bearing holding portion 18 at the center of the rotating shaft of the disk 10.
[0079]
Also, in the eleventh embodiment, as shown in FIG. 9, a brush body 31 is provided in a gap between the lower surface of the lower suction tool 2 and the disk 10 from the lower surface of the lower suction tool 2, and the brush body 31 is in contact with the disk 10. The brush body 31 is made of a conductive material.
[0080]
Next, the operation and action in this embodiment will be described.
Static electricity generated by the movement of the disk 10 on the surface to be cleaned can be transmitted to the suction tool body 1 through the conductive brush body 31, and a grounding structure is provided in the suction tool body 1 during cleaning. The generated static electricity is grounded each time, and the static electricity is grounded each time the suction tool body 1 is moved so that the dust is not attracted to the surface to be cleaned due to the static electricity, thereby facilitating dust collection.
[0081]
In the twelfth embodiment, as shown in FIG. 10, a roller 32 is provided on the lower surface of the lower suction tool 2 of the suction tool body 1.
[0082]
Next, the operation and action in this embodiment will be described.
When the suction tool main body 1 is operated, the disks 10 are inclined, so that the balance between the suction tool main body 1 and the surface to be cleaned is lost, and the grounding portion between the disk 10 and the surface to be cleaned rotates the disk 10. When the tangential line of the outer circumference circular contact portion 33 of the disk 10 is different from the advance angle of the suction tool main body 1 when it is displaced from the straight line connecting the shaft centers, the direction of travel of the suction tool main body 1 is different from the direction that the operator thinks. Is in contact with the surface to be cleaned, the force of the operator's operation is transmitted to the roller 32, and the advancing direction of the suction tool main body 1 is corrected in the front-rear direction of the suction tool main body 1 to prevent unstable operation. Moreover, the balance between the suction tool main body 1 and the surface to be cleaned can be maintained so that the cleaning pad 21 on the lower surface of the disk 10 uniformly contacts the surface to be cleaned.
[0083]
A thirteenth embodiment will be described with reference to FIG. The disk 10 is provided so that the outer peripheral part of the disk 10 protrudes outside the outer peripheral edge portion of the suction tool main body 1 either in the front-rear direction or the left-right direction. That is, the disc 20 is attached to the suction tool main body 1 as shown in FIGS. FIG. 4A shows the disk 10 attached so that it does not protrude from the outer periphery of the suction tool body 1, and the alternate long and short dash line in the figure indicates an obstacle such as a wall or a step.
[0084]
Next, the operation and action of this embodiment will be described.
If the outer periphery of the disk 10 protrudes from the outer peripheral edge of the suction tool body 1 when cleaning the wall (front / left and right), the disk 10 first hits the wall, and if the soft material is used for the disk 10 When the tool body 1 collides directly, the impact is reduced and a bumper effect is brought about. Further, when the suction tool main body 1 is moved left and right along the wall, the disk 10 can be rotated along the wall, so that the operation at the wall becomes easy.
[0085]
If the disk 10 comes out from behind the outer peripheral edge of the suction tool body 1, even if the suction tool body 1 collides at a place where there is a low step such as a sill with the momentum of operating the suction tool body 1, first the disk Therefore, if a soft material is used for the disk 10, the same bumper effect as described above can be obtained.
[0086]
Further, in the narrow gap where the suction tool main body 1 is difficult to enter, the disk 10 enters the gap, and the disk 10 rotates to sweep out dust to the front, making it easier to collect the dust.
[0087]
A fourteenth embodiment of the present invention will be described with reference to FIG.
A cleaning pad 21 is provided in the floor surface direction of the disk 10, and the cleaning pad 21 is formed in a cross shape passing through the center of rotation of the disk 10 and the cleaning pad 21 at a lower opening, intersecting at a right angle, and reaching the outer periphery of the disk 10. The groove 34 is provided.
[0088]
Next, the operation and action of the above configuration will be described. If the suction tool body 1 is placed on the surface to be cleaned to clean the floor surface, and suction is applied to collect dust while operating back and forth, suction air is generated in the suction port 4, and the outer periphery of the disk 10 is When the opening of the groove 34 passes through the vicinity of the suction port 4, suction air flows into the groove 34 and sucks dust on the lower surface of the disk 10.
[0089]
The fifteenth embodiment of the present invention will be described with reference to FIG.
Both the disk 10 and the cleaning pad 21 are constructed so that the center is pulled upward so that the disk 10 has a substantially conical shape as if an umbrella was opened.
[0090]
Next, the operation and action of the above configuration will be described. When the suction tool main body 1 is placed on the surface to be cleaned and pressed against the floor surface for cleaning, the disk 10 is as shown in FIG. 13, and the portion E is a portion that contacts when pressed against the surface to be cleaned. The volume of this E part is related to the operation resistance generated between the suction tool body 1 and the surface to be cleaned. In other words, the smaller the volume, the smaller the portion that touches the surface to be cleaned, so the resistance when operating becomes smaller. FL indicates a surface to be cleaned, and F indicates a recessed portion on a substantially conical shape.
[0091]
Then, the contact volume in the to-be-cleaned surface of the conventional disk shown in FIG. 14 and the disk 10 of this invention is compared. First, in FIG. 14, the contact volume of a conventional disk is expressed by the following equation.
[0092]
(Total volume of cleaning pad) = π × (r × r) × h
Since the contact volume is half of the entire cleaning pad (raised cloth 12),
(Conventional contact volume) = (π × (r × r) × h) / 2
Next, the contact volume of the disk 10 of the present invention is shown by an equation from FIG. The total volume and the contact volume of the cleaning pad 21 when not considering the concavity are the same as those described above. From this, the contact volume of the present invention can be obtained by subtracting the weight-like volume.
[0093]

From the above, it can be seen that the contact volume of the present invention is as small as one third that the cleaning pad 21 hits the surface to be cleaned compared to the conventional contact volume.
[0094]
Therefore, since the contact of the cleaning pad 21 with the surface to be cleaned is reduced, the operability is reduced and the cleaning can be performed more comfortably.
[0095]
The sixteenth embodiment of the present invention will be described below with reference to FIG. That is, a plurality of receiving openings 35 are provided on the outer peripheral edge portion of the disk 10.
[0096]
Next, the operation and action of the above configuration will be described. When the suction tool body 1 is moved forward to clean the floor surface, when there is extremely large dust, a plurality of cuts are provided in the outer periphery of the disk 10 to form the receiving port 35. Dust is stored in any of the plurality of receiving ports 35, and the disk 10 is rotated to be transported to the suction port 4 and sucked. As a result, in addition to powdery or fibrous dust, solid dust that has been difficult to collect can also be sucked, and the cleaning performance is improved.
[0097]
The seventeenth embodiment of the present invention will be described below with reference to FIG. In other words, the rotary cover 36 is provided so as to cover upward from the outer peripheral edge portion of the disk 10 and can freely rotate without being interlocked with the disk 10.
Next, the operation and action of the above configuration will be described. When cleaning the edge of the wall, if the rotary cover 36 is touched and operated, the rotary cover 36 operates in a non-interlocking manner with the disk 10, so that the operating direction of the suction tool body 1 is opposite to the rotational direction of the disk 10. Even if rotation unevenness occurs in the disk 10, the rotation cover 36 rotates in a non-interlocking manner, so that it rotates smoothly at the wall and assists the operation at the wall.
[0098]
Therefore, since the rotation cover 36 functions like a tire near the wall, even if the suction tool body 1 is operated sideways while being pressed against the wall, it rotates smoothly and becomes easier to operate.
[0099]
The eighteenth embodiment of the present invention will be described below with reference to FIG. That is, the anti-spinning tire 37 was provided so as to be sandwiched from above and below the outer peripheral edge of the disk 10 and wound around the outer periphery. The anti-spinning tire 37 is made of a material having a high coefficient of friction and high elasticity, and concave portions 38 and convex portions 39 are alternately provided on the entire upper surface of the anti-spinning tire 37. .
[0100]
Next, the operation and action of the above configuration will be described. When the anti-spinning tire 37 comes into contact with the surface to be cleaned, a larger frictional resistance is generated than when the cleaning pad 21 comes into contact, and the base point is fixed to the surface to be cleaned with a larger force, thereby reliably rotating.
[0101]
Thereby, since the effectiveness of the disk 10 and the cleaning pad 21 can be exerted on many surfaces to be cleaned, the cleaning performance with respect to the surface to be cleaned in a wider range is improved.
[0102]
If the disk 10 is constructed as in the twelfth embodiment of the present invention, the anti-spinning tire is made of a material rich in elasticity. Therefore, if the disk 10 is made of a bumper, the anti-spin tire 37 is made of a material rich in elasticity. Because it is composed of, the effect as a bumper can be obtained.
[0103]
