【０００１】
【発明の属する技術分野】
本発明は、掃除機本体の蓄電池を充電する充電器を備えた電気掃除機に関する。
【０００２】
【従来の技術】
従来、この種の電気掃除機としては、例えば特開平９−１０１５５号公報に記載の構成が知られている。
【０００３】
この特開平９−１０１５５号公報に記載の電気掃除機は、電動送風機およびこの電動送風機に電力を供給する蓄電池を収容し蓄電池に接続される充電部が後面部に設けられた掃除機本体を備えている。そして、この掃除機本体の下面には、掃除機本体の後面を床面に対向して載置する立位状態でホースを介して接続する延長管の取付手段を着脱可能に係止して取り付ける係合手段が設けられている。
【０００４】
また、掃除機本体の蓄電池を充電する充電器は、上面に掃除機本体を立位状態で載置可能で掃除機本体の充電部に接続する充電金具を有した載置部が設けられている。
【０００５】
そして、例えば掃除の中断や掃除の終了により収容する場合、掃除機本体の後面を床面に対向して載置する立位状態とし、この立位状態の掃除機本体の係合手段に延長管の取付手段を係止してホースを介して掃除機本体に接続した延長管を取り付けるスタンド収納形態とする。また、充電する場合には、このスタンド収納形態にした掃除機本体を、充電器の上面の載置部上に載置する。
【０００６】
【発明が解決しようとする課題】
しかしながら、特開平９−１０１５５号公報に記載の電気掃除機では、掃除機本体にホースを介して接続する延長管を取付手段により掃除機本体に取り付けるスタンド収納形態で充電器上に載置して充電するので、充電時の高さ寸法は、スタンド収納形態での高さ寸法より高くなり、スタンド収納状態では収納できる箇所であっても充電器に掃除機本体を載置する状態で収納できなくなるおそれがあり、収納する場合に不具合があるばかりでなく充電する場合にホースを外して充電したり、別の広い箇所で充電する必要が生ずるおそれがある。
【０００７】
本発明は、このような点に鑑みなされたもので、充電時における高さ寸法が高くなることを抑制して充電作業性が向上するとともに、掃除機本体を充電器に載置した状態での収納性が向上する電気掃除機を提供することを目的とする。

また、吸込口本体129には、下面に図示しない床面吸込口を開口し回転清掃体が回転自在に配設される吸込室を有している。そして、この吸込口本体129の後部略中央には、先端部が上方方向に回動可能でかつ回転可能に基端部が吸込室に向けて軸支され先端部に延長管128に接続されて床面吸込口を延長管128に連通させる連通管部137が設けられている。また、吸込口本体129には、ホース121および延長管128に配設された電線を介して掃除機本体１の蓄電池16から電力が供給されて回転清掃体を回転駆動させる図示しない電動機が配設されている。
【００４０】
一方、図１６ないし図１８において、141は充電器で、この充電器141は、上面が掃除機本体１の後面の曲面に対応して円弧凹状の載置部としての載置凹部142を有した略箱状のケース143を有している。そして、このケース143の載置凹部142には、掃除機本体１の充電部20に係合し充電部20の被充電端子に接続する図示しない充電端子である充電金具を内面に配設したスリット144を有した充電凸部145が突設されている。
【００４１】
また、ケース143の載置凹部142より前側には、上面が取手手段85の第２の取手87，87の後部に沿って略円弧状に形成され第２の取手87，87を載置する取手載置部146が設けられている。
【００４２】
さらに、ケース143の載置凹部142より後部には、取手載置部146の高さ寸法より高く載置凹部142に掃除機本体１が載置された状態で掃除機本体１の下面に当接する本体支持部147が壁状に上方に向けて突出形成されている。そして、本体支持部147の上端部となる頂部には、上方に向けて拡開するように爪案内面148aを有した爪取付部148が設けられている。さらに、この爪取付部148の底部には、本体ケース４の係合凹部30と同様に略四角筒状に形成され取付手段136の取付爪部135を着脱可能に係止して取り付ける保持手段としての取付凹部149が上方に向けて開口形成されている。なお、この取付凹部149は、取付手段136を取り付けた際に吸込口本体129の下面が床面に対向して載置される高さで、本体ケース４の後部を床面に対向して載置した立位状態で床面から係合凹部30までの高さ寸法と略同寸法に形成されている。すなわち、掃除機本体１の立位状態で取付手段136を係合凹部30に係止した状態が、同様に吸込口本体129の下面を床面に対向して載置した状態となっている。
【００４３】
また、ケース143の本体支持部147が設けられた側である後部には、略対角線方向に突出し下面が床面に当接する付属品取付部としての足部150，150が設けられている。そして、これら足部150，150の上面には、隙間ノズル131や家具ブラシ151などの付属品を取り付ける付属品取付凹部152，152がそれぞれ開口形成されている。なお、これら足部150，150は、取付凹部149に延長管128に取り付けられた取付手段136の取付爪部135を係止し延長管に接続する吸込口本体129の連通管部137を間に挿入するように、連通管部137の両側のデッドスペースに対応した位置に突設されている。
【００４４】
そして、付属品である隙間ノズル131には、図１６、図１７および図１９に示すように、軸方向に沿ってスリット状で延長管128に設けられた付属品取付手段132の首部が係脱可能に挿入係合し開口縁にて係止鍔部130を抜け止め係止するスリット部153を有した係止凹部154が設けられている。
【００４５】
また、家具ブラシ151は、図１７および図２０ないし図２３に示すように、下面に吸塵口160を開口し開口縁の外側にブラシ毛161が植設されたブラシ本体162と、このブラシ本体162に先端が吸塵口160に連通して軸支され基端に隙間ノズル131の先端が着脱可能に挿入係合する断面略楕円状の連通管部163が先端部に設けられた回転軸164にて回動可能に軸支されている。さらに、この連通管部163の外周面には、延長管128やホース121の把持部124の先端が略気密に嵌合する鍔状に突出したフランジ部166が設けられている。
【００４６】
そして、充電器141の各付属品取付凹部152，152は、図１９および図２０に示すように、内周面が家具ブラシ151の連通管部163が挿入係合可能な上方に向けて扁平筒状に形成され、底部に隙間ノズル131の先端に挿入係合可能に上方に向けて突出する取付凸部170が設けられている。
【００４７】
次に、上記実施の形態の動作を説明する。
【００４８】
まず、取手手段85の第１の取手86の吸込部61側である前側を持ちつつ吸込部61を両側から挟み込むようにして吸込部61の基端部の両側面60，60に臨む各鎖錠部75，75に連動して設けられた作動凸部79，79を付勢手段に抗して押し込むように操作し、作動部77をそれぞれ回動させて係止腕部81の係止爪部82をケース体２の係止部25の係止凹部24から外し、この状態で蓋体３をヒンジ部57，57にて上方に回動させ、集塵空間58の上方およびケース体２の上部を開放する。そして、あらかじめ第２のフィルタ108および第３のフィルタ113を取り付けた濾過部97を集塵カップ96に取り付けて構成した集塵部９を、ハンドル部98を持ってケース体２の装着下凹部31に下端部を挿入係合し、ケース体２の位置決め凸部42の係止凸部41をハンドル部98の下端に挿入係合して位置決めし、載置部10に保持して載置する。
【００４９】
この後、再び取手手段85を持って蓋体３を下面がケース体２の上面および集塵部９の上面に圧着して覆うように回動させて、集塵部９の上部を蓋体３の装着上凹部59に挿入係合させるとともに蓋体３の位置決め凹部70にハンドル部98の上部を係合して位置決めし、鎖錠部75，75の係止爪部82をケース体２の係止凹部24に係合し、本体ケース４の集塵空間58に集塵部９を装着する。この状態で、集塵部９の濾過部97の吸気筒部104の上端縁に蓋体３の吸込部61の吸込管63の下端が気密部材64を介して略気密に密着して連通するとともに、濾過部97の枠部110が蓋体３の装着上凹部59の下面に密着する状態で枠部110を介して集気開口106が蓋体３の通孔65に略気密に連通する。すなわち、吸込部61の本体吸込口62が、吸込部61の吸込管63、集塵部９の吸気筒部104、集塵カップ96内、集気筒部107、集気開口106、通孔65、吸気路66および連通孔21を介して電動送風機６の吸気口に連通する状態となる。
【００５０】
そして、吸込部61の本体吸込口62にホース121の接続管123を接続し、適宜延長管128を介して吸込口本体129を接続して、図３に示すような掃除待機状態とする。なお、吸込口本体129の代わりに付属品を接続したり、延長管128および吸込口本体129の代わりに付属品を接続するなどしてもよい。
【００５１】
この図３に示すような掃除待機状態で、ホース121の把持部124の操作手段126の操作により、適宜電動送風機６および電動機を駆動し、掃除する。なお、回路基板18に搭載された制御手段は、ホース121が接続されずに掃除待機状態となっていない場合には、誤作動を防止するために電動送風機６を駆動させない制御をする。
【００５２】
そして、吸込口本体129の下面に開口する図示しない床面吸込口から空気とともに塵埃を吸い込む。この吸い込んだ塵埃は、延長管128およびホース121を介して吸込部61の本体吸込口62から吸い込まれ、吸込部61の吸込管63を通って集塵部９の吸気筒部104から集塵カップ96内に集塵カップ96の内周面の接線方向に渦巻き状に吸い込まれる。そして、塵埃は渦巻き状に吸い込まれた空気の渦流の遠心力により集塵カップ96の内面に沿って落下し、空気は集塵カップ96の中心軸に位置する渦流の中心から集塵部９の濾過部97の第２のフィルタ108を通って集気筒部107から流出し、空気と塵埃とが分離される。さらに、分離された空気は、集塵部９の濾過部97に取り付けられた第３のフィルタ113にて空気中の分離されずに混入する微細な塵埃が除去されて枠部110を介して集塵部９から流出する。そして、この集塵部９から流出した空気は、集塵部９の枠部110と密着する蓋体３の装着上凹部59の通孔65から吸気路66を通過し、この吸気路66の下流側に略気密に連通するケース体２の連通孔21を通って電動送風機６の吸気口から吸気される。さらに、空気は、電動送風機６内を通って電動送風機室７内に排気され、さらに排気口26から外気に排気される。
【００５３】
また、付属品を用いて掃除する場合には、掃除箇所に応じて延長管128から吸込口本体129を取り外したり、ホース121の把持部124から吸込口本体129を接続した延長管128を取り外し、ホース121や延長管128の先端部に延長管128の付属品取付手段132に取り付けられた隙間ノズル131を取り付けて家具の隙間や窓枠のレール溝などの塵埃を吸塵する。なお、ホース121から取り外して掃除に利用しない延長管128は、取付手段136の取付爪部135を充電器141の取付凹部149に係合して取り付けておく。
【００５４】
さらに、家具ブラシ151を用いる場合には、隙間ノズル131の先端を家具ブラシ151の連通管部163に挿入嵌合して取り付ける。なお、家具ブラシ151をホース121や延長管128の先端部に直接取り付けて掃除する場合には、連通管部163を嵌合するようにホース121や延長管128の先端に取り付ける。この状態では、フランジ部166がホース121の把持部124の先端および延長管128の先端の内周面に密着するように嵌着して連通管部163とホース121の把持部124あるいは延長管128の先端部との間に隙間を生じることなく閉塞し、リークすることなく効率よく確実に吸塵する。
【００５５】
また、掃除場所を変更、例えば次の部屋を掃除するために掃除機本体１を持ち運んだり、階段などの掃除機本体１が走行できない場所で掃除機本体１を持ったまま掃除したり、乗用車などの車両内を掃除したり、収納場所まで持ち運んで収納場所の所定の位置に収容する場合などでは、取手手段85の第１の取手86または第２の取手87，87あるいは一体的に装着された集塵部９のハンドル部98を握って掃除機本体１を持ち上げる。ここで、第１の取手86、第２の取手87，87およびハンドル部98はそれぞれ軸方向が異なることから、把持する際に作業者が最も持ちやすい箇所を選択して把持すればよい。
【００５６】
なお、集塵部９は、蓋体３およびケース体２にて挟持されて保持され、上部が装着上凹部59に係合し下部が装着下凹部31に係合して位置決めされ、さらにハンドル部98の下端がケース体２の位置決め凸部42の係止凸部41に係止され、ハンドル部98の上部がケース体２の位置決め凹部70にて位置決め係止されており、本体ケース４に一体的に固定されて装着されていることから、集塵部９のハンドル部98も取手手段85と同様に掃除機本体１を持ち上げる取手として利用できる。
【００５７】
また、例えば家具の移動などのために掃除を中断する際、集塵部９のハンドル部98を持って掃除機本体１の後部が床面に対向して載置する立位状態とし、係合凹部30が上方に向けて開口する状態とする。この後、ホース121の把持部124を持ったまま延長管128の取付手段136の取付爪部135を係合凹部30に挿入して係止させ、延長管128をホース121および吸込口本体129を接続したまま取り付け、図２に示すようなスタンド収納状態とする。この取付手段136の取付爪部135を掃除機本体１の係合凹部30に挿入して係止する際、掃除機本体１が立位状態であることから、旋回輪36が車輪39の自重により車輪39が中心から下方に位置する状態となっており、係合凹部30の上方が車輪39やハウジング部40にて覆われない。そして、取付手段136の取付爪部135は、旋回輪36の案内側面38aと取付空間部32の内周面との間を案内されつつ係合凹部30に挿入される。なお、この延長管128を掃除機本体１に取り付けた状態で、集塵部９のハンドル部98を持って掃除機本体１を持ち運び可能である。
【００５８】
そして、ホース121の把持部124の操作手段126の設定操作により電動送風機６あるいは電動機を停止して掃除を終了した後は、鎖錠部75，75に連動して設けられた作動凸部79，79を再び操作して鎖錠部75，75による係止を解除してケース体２への蓋体３の連結状態を解除し、蓋体３を回動して集塵部９の上面およびケース体２の上面を開放し、ハンドル部98を持って集塵部９をケース体２から取り外す。この後、つまみ部102を持って集塵カップ96から濾過部97を取り外し、集塵カップ96内の捕捉した塵埃を排出する。また、適宜第１のフィルタ22、第２のフィルタ108および第３のフィルタ113を取り外して洗浄する。
【００５９】
次に、掃除機本体１の後面を充電器141の載置凹部142に挿入係合して載置するとともに、延長管128の取付手段136の取付爪部135を充電器141の取付凹部149に係合して吸込口本体129およびホース121を接続したままの状態で延長管128を充電器141に取り付け、図１に示すような充電状態とする。この取付手段136の取付爪部135を取付凹部149に挿入して係合する際に、爪案内面148aにて案内されつつ取付凹部149に挿入して係合する。この状態では、充電器141の足部150，150の間に吸込口本体129の連通管部137が位置する状態となる。
【００６０】
この掃除機本体１を充電器141に載置した状態で、掃除機本体１の充電部20に充電器141の充電凸部145が挿入係合し、掃除機本体１が位置決めされるとともに充電部20の被充電端子が充電凸部145の充電金具に接触して蓄電池16の充電が開始する。この充電の開始により、掃除機本体１の回路基板18の制御手段が表示手段89の充電中を点灯して充電中である旨を表示する。
【００６１】
一方、掃除の継続により蓄電池16の電荷の残量が少なくなると、回路基板18の制御手段は、リード線90を介して表示手段89の充電お知らせサインを点灯させて、電荷が少なくなって充電を要求する旨を報知する。そして、この報知により、掃除作業者は、掃除の終了時と同様に充電器141に掃除機本体１を載置して充電する。
【００６２】
上記実施の形態では、載置凹部142に載置された掃除機本体１の蓄電池16を充電する充電器141に、延長管128の取付手段136の取付爪部135を係止して取り付ける取付凹部149を、載置凹部142に載置した掃除機本体１の取付爪部135を係止して取り付ける係合凹部30の位置より低い位置に設けるため、充電器141の取付凹部149に延長管128の取付爪部135を係止して取り付けた場合の高さ寸法が、充電器141に載置した掃除機本体１の係合凹部30に延長管128の取付爪部135を係止して取り付けた場合の高さ寸法より低くなり、床面上に載置した掃除機本体１の係合凹部30に延長管128の取付爪部135を係止して取り付けたスタンド収納状態で収納可能な空間に収納でき、充電する場所に制約が生じることを防止でき、充電作業が容易にできる。
【００６３】
また、延長管128の取付爪部135を係合凹部30に係止する姿勢で載置凹部142に載置された掃除機本体１の蓄電池16を充電する充電器141に、延長管128の取付爪部135を係止して取り付ける取付凹部149を、掃除機本体１の係合凹部30に延長管128の取付爪部を係止するスタンド収納状態の姿勢における係合凹部30の高さ寸法と略同高さ寸法の位置に設けるため、充電器141の取付凹部149に延長管128の取付爪部135を係止して取り付けた充電状態での高さ寸法が、床面上に載置した掃除機本体１の係合凹部30に延長管128の取付爪部135を係止して取り付けたスタンド収納状態の高さ寸法と略同寸法となり、スタンド収納状態で収納可能な空間であれば充電でき、充電する場所に制約が生じることを防止でき、充電作業が容易にできる。
【００６４】
さらに、掃除機本体１の係合凹部30および充電器141の取付凹部149に延長管128の取付爪部135を取り付けた状態で吸込口本体129が床面に接地する状態としたため、安定して延長管128を取り付けできる。
【００６５】
また、載置凹部142に載置された掃除機本体１の蓄電池16を充電する充電器141の掃除機本体１を支持する上方に向けて突設した本体支持部147に延長管128の取付手段136の取付爪部135を着脱可能に係止して取り付ける取付凹部149を上方に向けて開口して略筒状に設けるため、取付爪部135の周面が取付凹部149の内面にて包まれる状態で係止されるので、取付凹部149に取付爪部135を係止した状態でホース121や延長管128に人が引っ掛かるなどの外力が作用しても取付爪部135が外れることを防止して安定して延長管128を取り付けできるとともに、掃除機本体１を支持する本体支持部147を利用して充電器141に延長管128を取り付けるための取付凹部149を設けるので、構造が簡略化して容易に充電器141を小型化できる。
【００６６】
そして、取付凹部149を本体支持部147の上端部に設けるため、取付凹部149を設けるために本体支持部147から外方に向けて突出する部分がなく、容易に構造が簡略化するとともに小型化でき、製造性を向上できる。
【００６７】
また、載置凹部142に載置された掃除機本体１の蓄電池16を充電する充電器141のケース143に、このケース143の本体支持部147に設けた取付凹部149に延長管128の取付爪部136を係止して延長管128を取り付けた状態で延長管128に接続する吸込口本体129の連通管部137の両側に位置して、隙間ノズル131や家具ブラシ151などの付属品を装着する付属品取付凹部152，152を有した足部150，150を設けるため、吸込口本体129の後端略中央に突出する連通管部137の両側のデッドスペースを有効利用でき、掃除機本体１を載置するとともに延長管128を取り付けた状態での領域を縮小でき、小さいスペースでも充電あるいは掃除機本体１の収容ができる。
【００６８】
さらに、掃除機本体１に取付爪部136を係脱可能に係止して延長管128を取り付ける係合凹部30を設けるため、充電器141に延長管128を取り付けるための取付爪部136を利用して、例えば掃除の中断などの際に屈んでホース121を床面に載置し再び屈んでホース121を把持して掃除を再開する必要がなく、ホース121および吸込口本体129を接続したままで延長管128を、後部が床面に載置する立位状態の掃除機本体１に屈むことなく取り付けでき、簡単な構成で掃除作業性を向上できる。
【００６９】
また、延長管128に取り付けた取付手段136の取付爪部135を着脱可能に係止して取り付ける本体ケース４の係合凹部30を、本体ケース４の下面に下方に向けて凹状で旋回輪36を配設する取付空間部32に連続し本体ケース４の後部を床面に対向して載置する立位状態で上方に向けて開口形成するため、旋回輪36を取り付けるための空間である取付空間部32を利用して取付爪部135を挿入するための係合凹部30の上方の開口が得られ、係合凹部30を本体ケース４の下面に設けるために本体ケース４の下面から下方に突出させることなく本体ケース４の下面と略面一に設けても容易に取付爪部135を係止または取外が容易にできるとともに、係合凹部30を本体ケース４の下面から突出しないので、掃除機本体１の走行際に係合凹部30が引っ掛かって走行性が低下したり、床面の段差に衝突して損傷することを防止できる。
【００７０】
また、本体ケース４に回転自在に略中央が軸支される外面が略球面状の台座部37の略中央から周縁に亘って突出形成したハウジング部40の先端部に車輪39を軸支して旋回輪36を構成し、係合凹部30の一縁を取付空間部32の内周面に連続して形成するため、本体ケース４の後部を床面に対向して載置する立位状態で車輪39の自重によりハウジング部40が上下方向に沿う状態となり、ハウジング部40の案内側面38aと取付空間部32の内周面との間で案内されるように取付手段136の取付爪部135が係合凹部30に係合して取り付けられるので、係合凹部30が本体ケース４の下面からほとんど突出することなく簡単な構成で容易に着脱できる構成が容易に得られる。
【００７１】
さらに、係合凹部30を電源室17の電源開口部29を開閉する開閉蓋部28に一体に設けて形成したため、別途係合凹部30を設けるための部材を用いる必要がなく部品点数が減少して、製造性を向上できる。
【００７２】
そして、略角筒状に形成した係合凹部30を開閉蓋部28に設けたため、取付手段136の取付爪部135を係止した状態でホース121や延長管128に外部から力が作用しても係合凹部30が損傷することを防止できる。
【００７３】
さらに、吸込口本体129の下面が床面に接地する状態で取付爪部135を係止するため、安定して取り付けできる。
【００７４】
また、取手手段85を吸込部61に連続して設け、ケース体２に配設される蓄電池16からのリード線90を取手手段85内に配線して、吸込部61に接続されるホース121や延長管128、吸込口本体129などに給電あるいは伝送するためのコネクタ91に接続するため、配設するために別途配線部分を隔離するための構成が不要となり、構成が簡略化して製造性を向上できるとともに、隔離するための空間が不要で既設の取手手段85を利用して容易に小型軽量化できる。
【００７５】
さらに、取手手段85の吸込部61との基端部の上面に表示手段89を配設するため、コネクタ91の配線と同様に、配線のための隔離が不要で構成が簡略化し製造性を向上できるとともに小型軽量化でき、掃除の際に把持される視認性が比較的高い取手手段85に位置するため、表示内容を容易に認識できる。そしてさらには、上面に配設したため、充電の際に充電器141に装着して立位状態となっても表示される充電状態を容易に認識できる。
【００７６】
また、取手手段85に本体ケース４の後部に亘り本体ケース４を立位状態とした際に床面に略当接する第２の取手87，87を設けるため、立位状態で載置した際にホース121や延長管128に引っ掛かるなどして外部から力が加わっても、第２の取手87，87が床面に当接し、転倒を防止できるとともに、この転倒を防止する構成が取手手段85の一部分を構成するので、別構成の転倒防止を設けることなく取手手段85の一部を利用して転倒を防止でき、構造が簡略化して製造性を向上できる。
【００７７】
さらには、ホース121を引っ張って掃除機本体１を移動させるなどにより引っ張り力が作用する吸込部61に取手手段85が連続するため、引っ張り力が作用して掃除機本体１の前側が持ち上げられてほぼ立位状態となっても取手手段85の第２の取手87，87により転倒を確実に防止できる。
【００７８】
また、取手手段85を蓋体３の前後方向の略全域に亘って設けたため、例えば掃除機本体１の後面を床面に対向させる立位状態とした際や、ホース121を引っ張って掃除機本体１を移動させる際に掃除機本体１の前側が持ち上げられてほぼ立位状態となっても、第２の取手87，87が床面に当接して転倒を防止でき、安定して掃除機本体１を立位状態で床面上に載置できるとともに、蓋体３を回動させて集塵部９の上面およびケース体２の上面を開放および閉塞させる動作が容易にできる。
【００７９】
さらに、取手手段85を第１の取手86およびこの第１の取手86を対称軸として略対称的に第１の取手86に対して分岐する状態に連結して対をなす転倒防止のための第２の取手87，87を一体に設けて取手手段85を略Ｙ字状に形成して第１の取手86が前側に吸込部61を設けた掃除機本体１に前後方向に沿うように設けるため、ホース121を接続して掃除する状態とすることにより重心の位置が掃除機本体１のみの場合の重心の位置より前側に移動する状態となっても、第１の取手86が重心の上方に位置するので、掃除形態により重心が移動しても重心の上方の位置で把持でき、安定して掃除機本体１を持ち上げることができ、作業性を向上できるとともに、第１の取手86の他に第２の取手87，87や第１の取手86と第２の取手87との分岐する部分、第２の取手87，87の分岐部分も手が挿入されて取手として利用でき、掃除形態に対応して作業者が最も持ちやすい部分を把持でき、取扱性が向上して掃除作業性を向上できる。
【００８０】
そしてさらに、掃除機本体１の重心の上方に位置して第１の取手86から第２の取手87，87が分岐する取手手段85を設けたため、作業者が最も持ちやすい箇所を選択して把持しても略重心の上方となるので、本体ケース４の安定した持ち運びが容易にでき、掃除作業性を向上できる。
【００８１】
また、蓋体３に突出形成した吸込部61から延出するように取手手段85を連続して形成し、集塵部９から電動送風機６の吸気口に連通させる吸気路66を形成する蓋体３の両側に位置してそれぞれ鎖錠部75，75を配設し、蓋体３から立ち上がる吸込部61の両側を挟み込むようにして一対の鎖錠部75，75に連動して設けた作動凸部79，79を操作させることにより係止状態が解除されて蓋体３を回動可能としたため、蓋体３を回動させるために把持する取手手段85の近傍に操作する作動凸部79，79が臨み、係止状態を解除して蓋体３を回動させる操作の操作性が向上するとともに、片方のみ操作したのでは係止状態を解除できないことから、取手手段85を持って掃除機本体１を持ち運ぶなどの動作の際に誤って鎖錠部75，75に連動して設けた作動凸部79，79を操作しても両方の作動凸部79，79が操作されない限り、係止状態が解除されて蓋体３が回動することを防止できる。特にサイクロン方式などのように、蓋体３に吸気路66が設けられる構成では、その両側を有効利用でき、小型化が容易に図れる。
【００８２】
そして、集塵した塵埃を排出するために回動させて集塵部９の上面およびケース体２の上面を開放させる蓋体３に取手手段85を設けたため、蓋体３を回動させるための取手を別途設ける必要がなく取手手段85を利用でき、構造を簡略化できる。
【００８３】
また、サイクロン方式で渦流から塵埃を効率よく分離するために集塵カップ96が上下方向に軸方向を有し上方に向けて開口する状態で本体ケース４に装着し、この集塵部９の上部を開放可能に覆うように蓋体３を設けるので、集塵部９の上部に開口し空気を排出する集気開口106を電動送風機６の吸気側に連通させる吸気路66を蓋体３に設けることができ、別途吸気路66を設ける構成に比して簡略化でき、製造性を向上できるとともに小型化できる。さらに、蓋体３の回動により開閉方向で集塵部９の集気開口106と電動送風機６の吸気側との略気密な連通および非連通状態が得られるので、これら集塵部９の上部および電動送風機６の吸気側と吸気路との略気密な連通が蓋体３の回動方向に沿った圧着により容易に得られ、簡単な構成で最小限のシール箇所で容易に略気密な連通が得られる。
【００８４】
そして、集塵空間58の上方およびケース体２の上方を覆う蓋体３としたため、集塵部９の集気開口106と電動送風機６の吸気側とを略気密に連通させる吸気路66を容易に簡単な構成で形成できるとともに、蓋体３の開閉により集塵部９の上部および電動送風機６の吸気側の上部が開放される状態となるので、集塵部９の着脱が容易にできる。さらに、着脱される集塵部９に着脱可能に設けた第２のフィルタ108および第３のフィルタ113と同様に、電動送風機６の吸気口から微細な塵埃が侵入することを防止するための第１のフィルタ22を着脱可能に設けることが簡単な構成で容易にできる。
【００８５】
また、集塵部９に集塵カップ96の上面の開口を覆う濾過部97を設けるため、簡単な構成で、掃除機本体１を立位状態で掃除しても塵埃がこぼれ落ちないようにできるとともに、塵埃を効率よく分離するための第２のフィルタ108および第３のフィルタ113を容易に着脱可能に装着でき、さらに蓋体３の吸込部61の本体吸込口62を電動送風機６の吸気口に連通させるための風路を容易に形成でき、製造性を向上できるとともに容易に小型軽量化できる。
【００８６】
また、本体ケース４の集塵空間58に電動送風機６の吸気側および本体吸込口62の間の吸気風路118に位置して着脱可能に装着され本体吸込口62から空気とともに吸い込んだ塵埃を捕捉して空気は電動送風機６の吸気側に流通させる集塵部９に、本体ケース４の外面から露出するハンドル部98を設けている。このため、集塵部９を本体ケース４から着脱する際にハンドル部98を持って容易に着脱できるとともにこの集塵部９を取り扱うために利用されるハンドル部98を本体ケース４を持ち上げる取手としても利用でき、例えば掃除機本体１の後部が床面に対向する立位状態とした場合に把持する取手を本体ケース４に設けることなくハンドル部98を把持すればよく、構成が簡略化して容易に小型化でき、製造性を向上できるとともに、掃除機本体１を持ち上げるなどの際に取手手段85と合わせて把持する方法が増大し、取扱性を向上できる。
【００８７】
そして、本体ケース４の電動送風機６を収容するケース体２と、このケース体２に取り付けられ集塵空間58を構成する蓋体３とにて、集塵部９を電動送風機６の吸気側および本体吸込口62間に略気密に連通する状態に挟持固定するため、簡単な構成で確実に集塵部９を本体ケース４に固定して一体的に装着でき、集塵部９のハンドル部98を持っても安定して掃除機本体１を持ち上げることができる。
【００８８】
また、ケース体２に集塵部９の下部周縁を挿入係合して覆う装着下凹部31を設けるとともに、蓋体３に集塵部９の上部周縁を挿入係合して覆う装着上凹部59を設けるため、集塵部９が本体ケース４により確実に一体的に装着できる。
【００８９】
さらに、ケース体２に集塵部９のハンドル部98の下端に挿入係合する係止凸部41を有した位置決め凸部42を設けるとともに、蓋体３にハンドル部98の上部が挿入係合する位置決め凹部70を設けてハンドル部98を位置決め固定するため、特に吸気した吸気流を渦流にして遠心力にて塵埃を分離するサイクロン方式により塵埃を捕捉するために円筒状に集塵カップ96を形成した集塵部９でも回転することなく確実で容易に位置決めでき、別途回り止めなどの位置決めするための構成を設けることなくハンドル部98を利用して位置決めでき、簡単な構成で容易に装置した集塵部９を固定できる。
【００９０】
そして、装着下凹部31および装着上凹部59にて集塵部９の上下部が覆われ、ハンドル部98が前方に突出する状態であることから、別途集塵部９の集塵カップ96を覆って保護する構成を設ける必要がなく、容易に小型化できる。
【００９１】
また、サイクロン方式で渦流から塵埃を効率よく分離するために集塵カップ96が上下方向に軸方向を有し上方に向けて開口する状態で本体ケース４に装着するため、集塵カップ96の外周にハンドル部98を容易に設けることができ、製造性を向上できる。
【００９２】
さらに、容易に剛性が得られる外殻となる蓋体３に吸込部61を設けるため、例えば集塵部９に直接吸込部61を設ける場合に比して、掃除の際にホース121を引っ張って掃除機本体１を走行させるなどの掃除作業をしても吸込部61が損傷することなく確実に大型化することなくホース121の連結状態が得られ、取扱性および掃除作業性を向上できる。
【００９３】
そして、集塵部９、電動送風機６および蓄電池16の順で重量が重く、この最も重い蓄電池16を集塵部９と電動送風機６の間に位置する本体ケース４の略中央に配設したため、旋回輪36および走行輪27，27の軸支位置の領域内に重心が位置して安定して床面上に載置でき、旋回輪36および走行輪27，27による安定した床面上での走行が得られ、掃除機本体１の取り回しが容易となって掃除作業性を向上できる。
【００９４】
また、この配置の順序は、掃除の際に引っ張られるホース121が接続される吸込部61が走行方向の前部に位置する状態で、走行方向の前側から集塵部９、蓄電池16、電動送風機６の順序としたため、ホース121を引っ張って掃除しても軽量な集塵部９が前側に位置するので、旋回などの方向転換が容易にできるとともに、後面が床面に対向した立位状態で床面上に対置した際に、比較的重い電動送風機６が下側に位置するので、立位状態としても安定して床面上に載置できる。
【００９５】
一方、家具ブラシ151の連通管部163を隙間ノズル131の先端部を嵌合する略楕円筒形状に形成し、外周面に延長管128やホース121の把持部124の先端を嵌合した際に連通管部163の外周側と延長管128やホース121の把持部124の先端の内周面との間を閉塞する鍔状のフランジ部166を設けたため、例えば隙間ノズル131を装着したままの状態で家具ブラシ151を取り付けることができ、隙間ノズル131に代えて家具ブラシ151を交換する必要がなく掃除作業性を向上でき、隙間ノズル131を用いることなく直接ホース121の把持部124や延長管128に接続してもリークを生じる隙間が形成されることを防止でき、効率よく吸塵できる。
【００９６】
そして、充電器141に延長管128の取付手段136の取付爪部135を係止する取付凹部149を設け、充電器141の転倒を防止するための足部150，150に隙間ノズル131および家具ブラシ151の双方を取り付けるための付属品取付凹部152，152を設けるため、充電の際や掃除の際に不要となった部品を充電器141に装着しておけばよく、掃除機本体１に掃除に利用されない部品を取り付けるための構成が不要となって、掃除の際に取り回される掃除機本体１を小型軽量化でき、掃除作業性および製造性を向上できる。さらに、充電器141の転倒防止用の足部150，150に付属品取付凹部152，152を設けるため、充電器141の構成を小型化できる。
【００９７】
なお、上記実施の形態において、サイクロン方式の集塵部９にハンドル部98を設けて説明したが、吸い込んだ空気を渦流とすることなく塵埃の自重により分離したり、集塵袋にて塵埃を捕捉する構成など、いずれの構成でもできる。
【００９８】
そして、充電器141としては、掃除機本体１を載置可能であれば載置部は凹状に限らず、また本体支持部147も掃除機本体１を支持可能ないずれの形状に形成できる。
【００９９】

【０１００】
さらに、本体支持部147の上端部に取付凹部149を設けたが、いずれの位置に設けてもよい。
【０１０１】
また、吸込口本体129を接地する状態で延長管128を取り付けて説明したが、接地させずに吊り下げ支持するように延長管128を取り付ける状態としてもよい。なお、吸込口本体129の下面が床面に対向する状態で取り付けることにより、より高さ寸法を低くできる。
【０１０２】
そして、係合凹部30を開閉蓋部28に設けたが、開閉蓋部28とは別に設けてもよく、掃除機本体１の後部や側部などに設けたり、設けなくてもよい。
【０１０３】
また、略角筒状に形成した係合凹部30を開閉蓋部28に設けたが、取付空間部32に連続する案内溝部35の下面の開口を開閉蓋部28に設けた例えば舌片状の閉塞板部にて閉塞し、案内溝部35の一部および閉塞板部にて取付空間部32に向けて開口する係合凹部30を構成してもよい。この構成によれば、簡単な構造で係合凹部30を形成でき、製造性を向上できる。なお、係合凹部30の強度を向上するために閉塞板部の近傍に本体ケース４に固定するリブなどを設けるとよい。
【０１０４】
そして、取付爪部135を有する取付手段136を延長管128に取り付けたが、例えば延長管135に直接取付爪部135を突設した構成としてもよい。
【０１０５】
また、旋回輪36は、上記実施の形態の構造に限らず、係合凹部30の取付空間部32に連続する部分を覆わないいずれの構成でもできる。
【０１０６】

[0072]
  Since the engagement recess 30 formed in a substantially rectangular tube shape is provided in the opening / closing lid portion 28, a force is applied to the hose 121 and the extension pipe 128 from the outside while the attachment claw portion 135 of the attachment means 136 is locked. Also, the engagement recess 30 can be prevented from being damaged.
[0073]
  Further, since the attachment claw portion 135 is locked in a state where the lower surface of the suction port body 129 is in contact with the floor surface, the attachment can be stably performed.
[0074]
  Further, the handle means 85 is provided continuously to the suction portion 61, the lead wire 90 from the storage battery 16 disposed in the case body 2 is wired in the handle means 85, and the hose 121 connected to the suction portion 61 Since it is connected to the connector 91 for supplying or transmitting power to the extension pipe 128, the inlet main body 129, etc., a configuration for isolating the wiring part is not necessary for installation, and the configuration is simplified and the productivity is improved. In addition, a space for isolation is unnecessary, and the existing handle means 85 can be used to easily reduce the size and weight.
[0075]
  In addition, since the display means 89 is disposed on the upper surface of the base end portion of the handle means 85 with the suction part 61, as with the wiring of the connector 91, no separation is required for the wiring and the configuration is simplified and the productivity is improved. In addition, it is possible to reduce the size and weight, and because it is located on the handle means 85 that is relatively highly visible to be gripped during cleaning, the display content can be easily recognized. Furthermore, since the battery is disposed on the upper surface, it is possible to easily recognize the state of charge displayed even when the battery 141 is attached to the charger 141 and is in the standing state.
[0076]
  Further, since the handle means 85 is provided with the second handles 87 and 87 that substantially come into contact with the floor surface when the main body case 4 is placed in the standing position over the rear portion of the main body case 4, Even if a force is applied from the outside by being caught by the hose 121 or the extension pipe 128, the second handles 87, 87 are brought into contact with the floor surface and can be prevented from overturning. Since a part is constituted, it is possible to prevent a fall by utilizing a part of the handle means 85 without providing a fall prevention of another configuration, and the structure can be simplified and the productivity can be improved.
[0077]
  Furthermore, since the handle means 85 continues to the suction portion 61 where the pulling force acts by pulling the hose 121 and moving the cleaner body 1, the pulling force acts to lift the front side of the cleaner body 1. Even in the almost standing position, the second handle 87, 87 of the handle means 85 can reliably prevent the fall.
[0078]
  In addition, since the handle means 85 is provided over substantially the entire front-rear direction of the lid 3, for example, when the rear surface of the cleaner body 1 is in a standing state facing the floor surface, or when the hose 121 is pulled, the cleaner body Even if the front side of the vacuum cleaner main body 1 is lifted up when the 1 is moved, the second handle 87, 87 can be brought into contact with the floor surface to prevent it from falling, and the vacuum cleaner main body can be stably 1 can be placed on the floor surface in an upright position, and the lid 3 can be rotated to easily open and close the upper surface of the dust collecting unit 9 and the upper surface of the case body 2.
[0079]
  Furthermore, the first handle 86 is connected to the first handle 86 and the first handle 86 in a state of bifurcating with respect to the first handle 86 with the first handle 86 as an axis of symmetry. The two handles 87, 87 are provided integrally and the handle means 85 is formed in a substantially Y shape so that the first handle 86 is provided along the front-rear direction in the vacuum cleaner body 1 provided with the suction portion 61 on the front side. Even if the position of the center of gravity moves to the front side of the position of the center of gravity in the case of only the cleaner body 1 by connecting the hose 121 and cleaning, the first handle 86 is located above the center of gravity. Therefore, even if the center of gravity moves depending on the cleaning mode, it can be gripped at a position above the center of gravity, the cleaner body 1 can be lifted stably, workability can be improved, and in addition to the first handle 86 The second handle 87, 87, the portion where the first handle 86 and the second handle 87 diverge, the second handle 87, 87 The hand can also be used as a handle by inserting a hand, and can handle the part that is most easily held by the operator in accordance with the cleaning mode, thereby improving the handleability and improving the cleaning workability.
[0080]
  In addition, since the grip means 85 is provided above the center of gravity of the vacuum cleaner main body 1 and the second handles 87 and 87 branch from the first handle 86, the operator selects and grips the position most easily held by the operator. However, since it is substantially above the center of gravity, the main body case 4 can be easily carried stably, and the cleaning workability can be improved.
[0081]
  Further, the handle body 85 is continuously formed so as to extend from the suction portion 61 that protrudes from the lid body 3, and the lid body that forms the intake passage 66 that communicates from the dust collection portion 9 to the intake port of the electric blower 6. 3 is provided with interlocking portions 75 and 75 located on both sides of the main body 3, and operating protrusions provided in conjunction with the pair of locking portions 75 and 75 so as to sandwich both sides of the suction portion 61 rising from the lid 3. By operating the portions 79, 79, the locked state is released and the lid 3 can be turned. Therefore, the operation convex portion 79, which is operated in the vicinity of the grip means 85 for gripping the lid 3 to rotate, 79, the operability of the operation of rotating the lid 3 by releasing the locked state is improved, and the locked state cannot be released by operating only one side. During operation such as carrying the main body 1, the operating projections 79 and 79 provided in conjunction with the locking portions 75 and 75 are accidentally operated. As long as both be of the actuating protrusion 79, 79 is not operated, the lid 3 locked state is released can be prevented from being rotated. In particular, in the configuration in which the intake passage 66 is provided in the lid 3 as in the cyclone method, both sides can be used effectively, and the size can be easily reduced.
[0082]
  And since the handle means 85 is provided in the cover body 3 which is rotated to discharge the collected dust and opens the upper surface of the dust collecting part 9 and the upper surface of the case body 2, the cover body 3 is rotated. There is no need to provide a handle separately, the handle means 85 can be used, and the structure can be simplified.
[0083]
  Further, in order to efficiently separate dust from the vortex flow by the cyclone method, the dust collecting cup 96 is attached to the main body case 4 with an axial direction in the vertical direction and opened upward, and an upper portion of the dust collecting portion 9 Since the lid 3 is provided so as to cover the air in an openable manner, an air intake passage 66 is provided in the lid 3 so as to communicate with the air intake side of the electric blower 6 through the air collection opening 106 that opens to the upper portion of the dust collecting portion 9 and discharges air. This can be simplified as compared with the configuration in which the intake passage 66 is separately provided, and the productivity can be improved and the size can be reduced. Further, since the lid 3 is rotated, a substantially airtight communication and non-communication state between the air collection opening 106 of the dust collection unit 9 and the intake side of the electric blower 6 is obtained in the opening and closing direction. In addition, the substantially airtight communication between the intake side of the electric blower 6 and the intake passage can be easily obtained by pressure bonding along the rotation direction of the lid 3, and the airtight communication can be easily performed with a simple structure and the minimum sealing position. Is obtained.
[0084]
  Since the lid 3 covers the upper part of the dust collection space 58 and the upper part of the case body 2, the air intake path 66 that allows the air collection opening 106 of the dust collection part 9 and the intake side of the electric blower 6 to communicate with each other in a substantially airtight manner is easily provided. In addition, since the upper part of the dust collecting part 9 and the upper part on the intake side of the electric blower 6 are opened by opening and closing the lid 3, the dust collecting part 9 can be easily attached and detached. Further, as in the case of the second filter 108 and the third filter 113 that are detachably provided on the detachable dust collecting portion 9, a second dust for preventing fine dust from entering from the air inlet of the electric blower 6. One filter 22 can be easily provided with a simple configuration.
[0085]
  In addition, since the filtering unit 97 that covers the opening on the upper surface of the dust collecting cup 96 is provided in the dust collecting unit 9, dust can be prevented from spilling even when the cleaner body 1 is cleaned in a standing position with a simple configuration. The second filter 108 and the third filter 113 for separating dust efficiently can be easily attached and detached, and the main body suction port 62 of the suction part 61 of the lid 3 is used as the suction port of the electric blower 6. An air passage for communication can be easily formed, productivity can be improved, and the size and weight can be easily reduced.
[0086]
  The dust collecting space 58 of the main body case 4 is positioned in the intake air passage 118 between the intake side of the electric blower 6 and the main body suction port 62 and is detachably mounted, and traps dust sucked together with air from the main body suction port 62. Thus, a handle portion 98 that is exposed from the outer surface of the main body case 4 is provided in the dust collecting portion 9 that circulates air to the intake side of the electric blower 6. For this reason, when attaching and detaching the dust collecting part 9 from the main body case 4, the handle part 98 can be easily attached and detached with the handle part 98 and the handle part 98 used for handling the dust collecting part 9 is used as a handle for lifting the main body case 4. For example, when the rear portion of the vacuum cleaner main body 1 is in a standing state facing the floor surface, the handle portion 98 may be gripped without providing the main body case 4 with a handle, and the configuration is simplified and easy. In addition, the manufacturability can be improved, and the method of gripping together with the handle means 85 when the cleaner body 1 is lifted or the like is increased, so that the handleability can be improved.
[0087]
  The dust collector 9 is connected to the intake side of the electric blower 6 by the case body 2 that houses the electric blower 6 of the main body case 4 and the lid body 3 that is attached to the case body 2 and constitutes the dust collection space 58. Since the main body suction port 62 is clamped and fixed in a state of being communicated in a substantially airtight manner, the dust collecting portion 9 can be securely fixed to the main body case 4 with a simple configuration and can be attached integrally. The handle portion 98 of the dust collecting portion 9 The vacuum cleaner main body 1 can be lifted stably even if it holds.
[0088]
  Further, a lower mounting recess 31 is provided in the case body 2 to cover the lower peripheral edge of the dust collecting portion 9 by inserting and engaging, and an upper mounting recess 59 to insert and engage the upper peripheral edge of the dust collecting portion 9 in the lid 3. For this reason, the dust collecting part 9 can be reliably mounted integrally by the main body case 4.
[0089]
  Further, the case body 2 is provided with a positioning convex portion 42 having a locking convex portion 41 inserted and engaged with the lower end of the handle portion 98 of the dust collecting portion 9, and the upper portion of the handle portion 98 is inserted and engaged with the lid 3. In order to trap and fix the handle 98 by positioning the positioning recess 70, the cylindrical dust collecting cup 96 is used to capture dust by a cyclone system that separates dust by centrifugal force using a vortex flow of the intake air. The formed dust collecting part 9 can be positioned reliably and easily without rotating, and can be positioned using the handle part 98 without providing a separate positioning structure such as a detent, and the apparatus is easily configured with a simple configuration. The dust collection part 9 can be fixed.
[0090]
  Since the upper and lower portions of the dust collecting portion 9 are covered by the mounting lower concave portion 31 and the mounting upper concave portion 59 and the handle portion 98 protrudes forward, the dust collecting cup 96 of the dust collecting portion 9 is separately covered. Therefore, it is not necessary to provide a protective structure, and the size can be easily reduced.
[0091]
  Further, in order to efficiently separate dust from the vortex flow by the cyclone method, the dust collecting cup 96 is attached to the main body case 4 with an axial direction in the vertical direction and opened upward. The handle portion 98 can be easily provided to improve the manufacturability.
[0092]
  Furthermore, in order to provide the suction part 61 in the lid 3 as an outer shell that can easily obtain rigidity, the hose 121 is pulled during cleaning as compared with the case where the suction part 61 is provided directly in the dust collection part 9, for example. Even if a cleaning operation such as running the cleaner body 1 is performed, the suction portion 61 is not damaged and the hose 121 can be connected without being enlarged without fail, so that the handling and cleaning workability can be improved.
[0093]
  And since the weight is heavy in the order of the dust collector 9, the electric blower 6 and the storage battery 16, and this heaviest storage battery 16 is disposed at the approximate center of the main body case 4 located between the dust collector 9 and the electric blower 6, The center of gravity is located in the region of the pivot support position of the swivel wheel 36 and the traveling wheels 27, 27 and can be stably placed on the floor surface. Traveling is obtained, the handling of the cleaner body 1 is facilitated, and the cleaning workability can be improved.
[0094]
  In addition, the arrangement order is such that the suction part 61 to which the hose 121 pulled during cleaning is connected is located at the front part in the traveling direction, and the dust collecting unit 9, the storage battery 16, the electric blower from the front side in the traveling direction. 6 so that even if the hose 121 is pulled and cleaned, the lightweight dust collecting portion 9 is located on the front side, so that it is possible to easily change the direction such as turning, and the rear surface is in a standing state facing the floor surface.
