Description

【０００１】
【発明の属する技術分野】
本発明は、取手手段に連続し掃除具を電気的かつ機械的に接続する吸込部を有した取手手段を備えた電気掃除機に関する。
【０００２】
【従来の技術】
従来の電気掃除機として、例えば特開平７−１４８０９７号公報に記載の構成が知られている。
【０００３】
この特開平７−１４８０９７号公報に記載の電気掃除機は、電動送風機を収容する電動送風機室および電動送風機の吸気側に連通する集塵室を区画形成する本体ケースの前側略中央に、集塵室に連通して前方に開口し掃除具であるホースの基端の接続管を着脱可能に接続する吸込部を設けている。そして、この吸込部には、ホースの接続管に設けられた端子ピンに接続する端子金具が配設されている。これにより、例えば、ホースの先端に形成される手元操作部と掃除機本体との電気的接続がなされたり、掃除機本体の電源からホースおよび延長管を介して吸込口体の電動機に給電したりする構成が採られている。
【０００４】
【発明が解決しようとする課題】
しかしながら、この特開平７−１４８０９７号公報に記載の電気掃除機では、端子金具に接続する電線が吸込部から集塵室を介して電動送風機室に至る風路に電線が露出しないようにカバーなどにて隔離して配設する必要があり、構成が複雑となって製造性の向上が図りにくいとともに、電線を隔離して配線するための空間により小型化が困難である問題がある。
【０００５】
本発明は、上記問題点に鑑みなされたもので、隔離して配線するための空間が不要となり小型化可能で構成が簡略化する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】
請求項１記載の電気掃除機は、電動送風機を収容するケース体と、このケース体に取り付けられ、このケース体の上面を開放可能に覆う蓋体とを備えた本体ケースと、前記蓋体に設けられ、前記ケース体内に連通する電線収容部を内部に連続的に有する取手手段と、この取手手段に連続して前記蓋体に設けられ掃除具が前記電動送風機の吸気側に連通させて接続する吸込部と、この吸込部に設けられ前記掃除具に電気的に接続される端子部と、前記取手手段の電線収容部内に配線され一端側が前記ケース体内へと挿入接続され他端側が前記端子部に接続される電線とを具備したものである。
【０００７】
そして、電動送風機を収容するケース体の上面を開放可能に覆う蓋体に設けた取手手段に連続し掃除具を電動送風機の吸気側に連通させて接続する吸込部に掃除具に電気的に接続する端子部を配設し、この端子部に取手手段の内部に連続的に形成されケース体内に連通する電線収容部内に配線され一端側がケース体内に挿入接続された電線の他端側を接続することにより、本体ケース内を隔離して配線する必要がなく取手手段を利用して配線され、本体ケース内に隔離して配線するための空間が不要となって、小型化および構成の簡略化が容易となる。
【０００８】
請求項２記載の電気掃除機は、請求項１記載の電気掃除機において、取手手段に配設され電線に接続される表示手段を具備したものである。
【０００９】
そして、電線に接続する表示手段を取手手段に設けることにより、配線が容易となるとともに視認性の高い取手手段に位置する表示手段による表示が容易に認識可能となる。

さらに、濾過部97の蓋部101の略中央には、つまみ部102が設けられた周縁近傍に変位した位置に下方に向けて円筒状で下端が嵌合部100の接線方向に沿った側方に向けて吸気開口103を開口する吸気筒部104が設けられている。また、蓋部101の略中央には略円形の集気開口106が開口形成され、この集気開口106の周縁には下方に向けて略円筒状に突出する集気筒部107が設けられている。なお、蓋部101は、吸気筒部104の位置から次第に下端側に向けて集気筒部107の外周面で螺旋状となるように形成されている。そして、集気筒部107には、底部が円弧状に閉塞された有底円筒状で通気性を有する網目部材にて形成された第２のフィルタ108が着脱可能に取り付けられている。
【００３０】
また、濾過部97には、嵌合部100の上端面の開口に着脱可能に取り付けられる格子状の枠部110が設けられている。そして、枠部110には、吸気筒部104を係合する凹状の案内凹部111が設けられている。また、枠部110には、上方に向けて舌片状に突出する操作つまみ112が設けられている。そして、蓋部101と枠部110との間には、通気性を有する第３のフィルタ113が着脱可能に集気開口106を覆って取り付けられている。なお、第３のフィルタ113は、蓋部101の周縁近傍に上方に向けて略放射壁状に突出する保持リブ114上に載置して集気開口106との間に集気空間115を開口して第３のフィルタ113の略全体を通気するように取り付けられている。これら第２のフィルタ108および第３のフィルタ113にて第１の濾過体が構成される。
【００３１】
そして、濾過部97のつまみ部102をハンドル部98に係合して集塵カップ96に取り付けて集塵部９を構成した状態で、集塵カップ96の下部をケース体２の装着下凹部38に嵌挿係合して収容させ上部を蓋体３の装着上凹部59に嵌挿係合して収容させ、集塵部９を蓋体３とケース体２とにて挟持するように本体ケース４の集塵空間58に装着する。この装着した状態では、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、枠部110が蓋体３の通孔65に封止部材117にて略気密に密着して連通する。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25を介して電動送風機６の吸気口に連通する状態となり、この本体吸込口62から電動送風機６の吸気口に至る吸気風路118に集塵部９が位置する状態となる。
【００３２】
また、集塵部９は、ハンドル部98の下端に位置決め凸部42の係止凸部41が係合し、ハンドル部98の上部が蓋体３の位置決め凹部70に係合し、回り止めされて位置決め固定される。なお、覆い部71は、外面がハンドル部98の外面に連続するようにつまみ部102の先端部が上方に向けて突出するハンドル部98の上部を覆った状態となる。なお、この集塵部９は、電動送風機６および蓄電池18より軽量、すなわち、重量は集塵部９＜電動送風機６＜蓄電池18の関係で重くなっている。
【００３３】
一方、図６において、121は掃除具としてのホースで、ホース121は、可撓性を有し図示しない電線がスパイラル状に設けられたホース本体122と、このホース本体122の一端である基端に設けられ掃除機本体１の吸込部61の本体吸込口62に嵌合接続する接続管123と、ホース本体122の他端である先端に設けられた略く字状に屈曲する把持部124とを備えている。そして、接続管123には、電線の一端に接続され吸込部61に配設されたコネクタ91に接続される図示しない端子ピンが配設されている。さらに、把持部124には、屈曲する部分の基端側に面する部分に電線に接続され電動送風機６などの駆動を設定する各種ボタン125，125を有した操作手段126が配設されている。
【００３４】

【００３５】
一方、図１３ないし図１７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22に係合し充電部22の充電端子に接続する図示しない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。また、ケース143の後部には、取付手段136の取付爪部135を係止する取付凹部146が設けられている。さらに、ケース143の後部には、略対角線方向に突出し下面が床面に当接する足部148，148が設けられている。そして、これら足部148，148の上面には、隙間ノズル131や家具ブラシ149などの付属品を取り付ける付属品取付凹部150，150がそれぞれ開口形成されている。
【００３６】
そして、付属品である隙間ノズル131には、図１３、図１４および図１６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部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。
【００３７】
また、家具ブラシ149は、図１４および図１８ないし図２０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。
【００３８】
そして、充電器141の各付属品取付凹部150，150は、図１６および図１７に示すように、内周面が家具ブラシ149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。
【００３９】
次に、上記実施の形態の動作を説明する。
【００４０】
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29の係止凹部28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38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。
【００４１】
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28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25を介して電動送風機６の吸気口に連通する状態となる。
【００４２】
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。
【００４３】
この掃除待機状態で、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20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。
【００４４】
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25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31から外気に排気される。
【００４５】
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の付属品取付部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146に係合して取り付けておく。また、家具ブラシ149を用いる場合には、隙間ノズル131の先端を家具ブラシ149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149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。
【００４６】
さらに、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。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38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。
【００４７】
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26、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。
【００４８】
次に、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146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、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。この状態で、掃除機本体１の充電部22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22の充電端子が充電凸部145の充電金具に接触して蓄電池18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20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。
【００４９】
一方、掃除の継続により蓄電池18の電荷の残量が少なくなると、回路基板20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。
【００５０】
上記実施の形態では、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18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。
【００５１】
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。
【００５２】
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。
【００５３】
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。
【００５４】
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。
【００５５】
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。
【００５６】
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。
【００５７】
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。
【００５８】
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。
【００５９】
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。
【００６０】
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26を着脱可能に設けることが簡単な構成で容易にできる。
【００６１】
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。
【００６２】
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。
【００６３】
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。
【００６４】
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38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。
【００６５】
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。
【００６６】
そして、装着下凹部38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。
【００６７】
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。
【００６８】
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。
【００６９】
そして、集塵部９、電動送風機６および蓄電池18の順で重量が重く、この最も重い蓄電池18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39および走行輪33，33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39および走行輪33，33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。
【００７０】
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18、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。
【００７１】
一方、家具ブラシ149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149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149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。
【００７２】
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146を設け、充電器141の転倒を防止するための足部148，148に隙間ノズル131および家具ブラシ149の双方を取り付けるための付属品取付凹部150，150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148，148に付属品取付凹部150，150を設けるため、充電器141の構成を小型化できる。
【００７３】
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。
【００７４】
また、ホース121を介して延長管128や吸込口本体129を接続するキャニスタ型の電気掃除機について説明したが、吸込部61に掃除具としての延長管128が接続される形態のアップライト型、吸込部61に直接掃除具としての吸込口本体129が接続されるハンディ型などでも適用できる。
【００７５】
さらに、取手手段85に表示手段89を配設したが、設けなくてもよく、さらには取手手段85に電動送風機６の駆動状態を設定するリード線90に接続される操作スイッチなどを配設してもよい。また、取手手段85に配設されたリード線90は、回路基板20と操作手段126とを電気的に接続するために設けたが、例えば掃除機本体１の蓄電池18などの電源部と吸込口本体129に設けられる電動機とを電気的に接続するために用いてもよい。すなわち、掃除機本体１に設けた電源部と掃除具に設けられた電気的手段とを接続するための電線を取手手段85内に設ければよい。
【００７６】
そして、第１の取手86から略Ｙ字状に第２の取手87，87を略Ｙ字状に分岐して形成したが、例えば略Ｔ字状に分岐したり、２つに限らず複数分岐させたものなど、いずれの形状とすることもできる。
【００７７】
さらに、集塵部９として、濾過部97を設けたが、集塵部９を集塵カップ96のみとして濾過部97の構成を蓋体３やケース体２に設けるなどしてもよい。
【００７８】
また、第１の濾過体は第１のフィルタ26に限らずいずれのものでもよく設けなくてもよい。さらに、第２の濾過体は第２のフィルタ108および第３のフィルタ113のいずれか一方のみあるいはいずれのもの、さらにはこれらを設けなくてもよい。
【００７９】
そして、集塵部９を蓋体３とケース体２にて挟持したが、挟持することなく他の構成により集塵部９を固定してもよい。
【００８０】
また、装着下凹部38および装着上凹部59のいずれか一方のみでもよく、またこれらを設けずに他の構成により集塵部９を固定してもよい。
【００８１】
さらに、係止凸部41を有する位置決め凸部42および位置決め凹部70のいずれか一方のみ、あるいはこれらを設けずに他の構成により位置決めしてもよい。
【００８２】
そして、蓋体３は、集塵部９の上部およびケース体２の上部のほぼ全体を開放可能に覆うものに限らず、集塵部９の上部のみを開放可能に覆ってもよい。
【００８３】
さらに、蓋体３の取手手段85はいずれの構成でもよい。
【００８４】
また、バッテリとして蓄電池18を電源に用いたが、例えば電源コードを介して商用交流電源を供給したり乾電池を用いてもよい。
【００８５】
そして、付属品はいずれのものでもよく、また付属品を設けなくてもよい。
【００８６】
さらに、付属品を取り付ける構成としては、いずれの構成でもできる。
【００８７】
【発明の効果】
請求項１記載の電気掃除機によれば、ケース体の上面を開放可能に覆う蓋体に設けた取手手段に連続する吸込部の端子部に、取手手段の内部に連続的に形成されケース体内に連通する電線収容部内に配線され一端側がケース体内に挿入接続された電線の他端側を接続するため、本体ケース内を隔離して配線する必要がなく取手手段を利用して配線でき、本体ケース内に隔離して配線するための空間が不要となって、小型化および構成の簡略化が容易にできる。

It closes without generating a gap with the tip of the tube, and efficiently and reliably absorbs dust without leaking.
[0046]
Furthermore, the cleaning place is changed, for example, the cleaner body 1 is carried in order to clean the next room, the cleaner body 1 is cleaned in a place where the cleaner body 1 cannot run, such as stairs, or a passenger car, etc. The first handle 86 or the second handles 87, 87 of the handle means 85 or the integrated means are mounted integrally when the inside of the vehicle is cleaned or carried to the storage location and stored at a predetermined position in the storage location. The vacuum cleaner body 1 is lifted by grasping the handle portion 98 of the dust collecting portion 9. Here, since the first handle 86, the second handles 87, 87, and the handle portion 98 have different axial directions, the operator can select and hold the portion that is most easily held by the operator. The dust collecting portion 9 is sandwiched and held by the lid 3 and the case body 2, and the upper portion engages with the mounting upper recess 59 and the lower portion engages with the mounting lower recess 38, and is further positioned. The lower end of 98 is locked to the locking convex portion 41 of the positioning convex portion 42 of the case body 2, and the upper portion of the handle portion 98 is positioned and locked by the positioning concave portion 70 of the case body 2. Therefore, the handle portion 98 of the dust collecting portion 9 can be used as a handle for lifting the cleaner body 1 in the same manner as the handle means 85.
[0047]
Then, after the electric blower 6 or the electric motor is stopped by the setting operation of the operating means 126 of the grip portion 124 of the hose 121 and the cleaning is finished, the operation convex portions 79 provided in conjunction with the lock portions 75, 75, 79 is operated again to release the locking by the lock portions 75, 75 to release the connection state of the lid body 3 to the case body 2, and the lid body 3 is rotated to rotate the upper surface of the dust collecting portion 9 and the case. The upper surface of the body 2 is opened, and the dust collector 9 is removed from the case body 2 with the handle portion 98. Thereafter, the filter part 97 is removed from the dust collection cup 96 with the knob part 102, and the dust trapped in the dust collection cup 96 is discharged. Further, the first filter 26, the second filter 108, and the third filter 113 are appropriately removed and washed.
[0048]
Next, the extension tube 128 is connected to the charger 141 while the suction inlet body 129 and the hose 121 remain connected by engaging the attachment claw portion 135 of the attachment means 136 of the extension tube 128 with the attachment recess 146 of the charger 141. Attach and place the rear surface of the vacuum cleaner main body 1 into the mounting recess 142 of the charger 141 by insertion engagement. In this state, the charging convex portion 145 of the charger 141 is inserted and engaged with the charging portion 22 of the cleaner main body 1, the cleaner main body 1 is positioned, and the charging terminal of the charging portion 22 is the charging bracket of the charging convex portion 145. The storage battery 18 starts charging. By the start of this charging, the control means of the circuit board 20 of the cleaner body 1 lights up the charging of the display means 89 to display that charging is in progress.
[0049]
On the other hand, when the remaining amount of charge of the storage battery 18 decreases due to continued cleaning, the control means of the circuit board 20 turns on the charging notice sign of the display means 89 via the lead wire 90, and the charge decreases to charge. Inform the request. By this notification, the cleaning operator places the cleaner main body 1 on the charger 141 and charges it in the same manner as at the end of cleaning.
[0050]
In the above embodiment, the handle means 85 is provided continuously to the suction portion 61, and the lead wire 90 from the storage battery 18 disposed in the case body 2 is wired in the handle means 85 and connected to the suction portion 61. Because it is connected to the connector 91 for supplying or transmitting power to the hose 121, the extension pipe 128, the suction inlet main body 129, etc., it is not necessary to separately provide a configuration for isolating the wiring part for installation, and the configuration is simplified. Manufacturability can be improved, and a space for isolation is unnecessary, and the existing handle means 85 can be used to easily reduce the size and weight.
[0051]
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.
[0052]
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.
[0053]
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.
[0054]
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.
[0055]
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.
[0056]
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.
[0057]
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.

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.
[0058]
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.
[0059]
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.
[0060]
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.

[0061]
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.
[0062]
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.
