【０００１】
【発明の属する技術分野】
本発明は、集塵部を装着するケース体に蓋体を設け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、例えば集塵袋を用いる構成が知られている。この集塵袋を用いる電気掃除機は、電動送風機を収容する電動送風機室の前面に上面が蓋体にて開閉され内部に集塵袋が着脱可能に装着される集塵室を有したケース体を有している。また、このケース体の前部には、ホースが着脱可能に接続され集塵室の集塵袋内に連通する吸込口が設けられている。
【０００３】
そして、ホースを介して空気とともに吸い込まれた塵埃は、集塵室内に装着した集塵袋内に捕捉され、空気のみが濾過されて電動送風機の吸気口から吸気される。また、塵埃が一杯になった集塵袋は、蓋体を回動して集塵室の上面を開口させ、この開口する部分から集塵袋を取り外して集塵袋とともに廃棄し、別の新しい集塵袋を集塵室内に装着する。
【０００４】
しかしながら、この集塵袋を用いる電気掃除機本体では、集塵した集塵袋を廃棄するので、掃除コストの低減が図れない。
【０００５】
そこで、例えば特公昭５８−１９３６号公報などに記載の構成が知られている。
【０００６】
この特公昭５８−１９３６号公報に記載の電気掃除機は、電動送風機を収容するケース体と、このケース体の吸気側である前側に着脱可能に取り付けられホースを接続する吸込口を有する集塵ケースとを備えている。そして、ケース体は、前面に電動送風機の吸気口に連通する連通孔を開口している。一方、集塵ケースは、吸込口が前面に開口し後面にケース体の前側周縁に対向して連通孔に連通する開口部を開口している。また、この集塵ケースの開口部には、フィルタ体が着脱可能に閉塞して取り付けられて、内部に集塵室が区画形成される。そして、ケース体の前部に集塵ケースが着脱可能に一体的に取り付けられて本体ケースを構成する。
【０００７】
また、掃除に際しては、集塵ケースをケース体の前側に取り付け、電動送風機の吸気口がフィルタ体を介して集塵ケース内の集塵室に連通する状態とする。この後、電動送風機を駆動させ、集塵ケースの吸込口に接続したホースを介して空気とともに吸い込んだ塵埃が集塵室内に流入し、塵埃はフィルタ体にて分離されて空気のみが濾過されて電動送風機の吸気口から吸い込まれてケース体内に排気され、さらに外気に排気される。
【０００８】
そして、集塵ケースの集塵室内に捕捉した塵埃は、集塵ケースをケース体から取り外し、フィルタ体を集塵ケースから取り外して開口部を開口し、開口部を下方に向くように反転させて開口する開口部から塵埃を排出する構成が採られている。
【０００９】
しかしながら、上記特公昭５８−１９３６号公報などに記載の電気掃除機では、集塵ケース内に吸い込んだ塵埃を含む空気を直接フィルタ体にて濾過するので、フィルタ体が目詰まりしやすく、頻繁にフィルタ体を洗浄する必要があり、掃除作業が煩雑となる。
【００１０】
そこで、塵埃を含んだ空気を渦巻き状に流し、その間に塵埃をそれ自身の重力により落下させ塵埃と空気とを分離する構成が考えられる。
【００１１】
【発明が解決しようとする課題】
ところで、上記塵埃をそれ自身の重力により落下して分離する構成では、効率よく塵埃を分離除去するために、集塵ケースの上方から塵埃とともに空気を吸い込み遠心力で外方に吹き飛ばした塵埃を自重により落下させ、空気は塵埃の落下方向と反対側の集塵ケースの上方から排出する必要がある。
【００１２】
このことから、塵埃が除去して上方から空気を引き抜くために電動送風機の吸気側と集塵ケースの上部とを連通する風路を形成する必要がある。
【００１３】
本発明は、このような点に鑑みなされたもので、簡単な構成で効率よく吸塵した塵埃を捕捉できる電気掃除機を提供することを目的とする。
【００１４】
【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とともに、上面に開口し前記電動送風機の吸気口に連通する連通孔を有するケース体と、このケース体に着脱可能に装着され上部に空気とともに吸い込んだ塵埃が内部に流通可能な吸気開口および内部に流入した空気が流通可能な集気開口を開口する集塵部と、この集塵部の上部および前記ケース体の前記連通孔を開放可能に覆って前記ケース体に取り付けられた蓋体と、この蓋体に設けられ前記集塵部の上部および前記ケース体の上面を覆った状態で前記集塵部の集気開口と前記連通孔とを連通させる吸気路と、前記連通孔を覆って前記ケース体に設けられた第２の濾過体とを具備したものである。
【００１５】
そして、上部に空気とともに吸い込んだ塵埃を内部に流通可能な吸気開口と内部に流入した空気が流通可能な集気開口を開口する集塵部の上部およびケース体の挿通孔を開放可能に覆ってケース体に取り付けられる蓋体に、集塵部の上部を覆った状態で集塵部の集気開口をケース体の電動送風機の吸気口に連通させる吸気路を設けることにより、集塵部の上部とケース体の上面に開口し電動送風機の吸気口に連通する連通孔とを連通させる風路を蓋体のみに設ければよく、吸気路を別途設けることなく集塵部を着脱するための蓋体を利用するので、吸気路の構成が簡略化するとともに、別途の吸気路により集塵部の着脱操作が損なわれることがなく、かつ、集塵部の上部と電動送風機の吸気口とが簡単な構成で容易に略気密に連通し、さらに、電動送風機の吸気口に連通する連通孔を覆う第２の濾過体をケース体に設けることにより、吸い込んだ空気から第２の濾過体にて確実に塵埃が取り除かれて電動送風機の吸気口から流入することによる吸気効率の低下や損傷などの弊害を防止し、集塵部の上部およびケース体の上面を開放可能に覆う構成にてケース体に設けられた第２の濾過体の保守点検が容易となり、長期間安定した特性が容易に得られる。
【００１６】
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、集塵部の集気開口を覆って前記集塵部に設けられた第１の濾過体を具備したものである。
【００１７】
そして、集塵部の集気開口を覆う第１の濾過体を設けることにより、第１の濾過体および第２の濾過体にて吸い込んだ空気から確実に塵埃が取り除かれて電動送風機の吸気口から流入することによる吸気効率の低下や損傷などの弊害を防止し、集塵部の上部およびケース体の上面を開放可能に覆う構成にて第１の濾過体の保守点検も容易となり、長期間安定した特性が容易に得られる。

【００４３】
次に、上記実施の形態の動作を説明する。
【００４４】
まず、取手手段85の第１の取手86の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の基端部に臨む各鎖錠部75，75の作動凸部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。

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、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。
【００４６】
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。
【００４７】
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。
【００４８】
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。
【００４９】
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129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。
【００５０】
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。
【００５１】
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を再び操作して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。
【００５２】
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。
【００５３】
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。
【００５４】
上記実施の形態では、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を集塵部９を着脱するための蓋体３に設けることができ、集塵部９の着脱操作を損なうことなく別途吸気路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。
【００５５】
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。
【００５６】
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。
【００５７】
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。
【００５８】
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。
【００５９】
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。
【００６０】
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。
【００６１】
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。
【００６２】
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。
【００６３】
そして、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。
【００６４】
また、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、従動輪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る。
【００６５】
そして、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。
【００６６】
一方、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することができ、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。
【００６７】
そして、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。
【００６８】
さらに、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。
【００６９】
また、取手手段85を吸込部61に連続して設けたため、ケース体２に配設される蓄電池18からの配線を取手手段85内を配線して、吸込部61に接続されるホース121などに給電することができ、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、容易に小型軽量化できる。
【００７０】
さらに、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。
【００７１】
そして、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を連続して形成したため、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、係止状態を解除す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の作動凸部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。
【００７２】
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。
【００７３】
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。
【００７４】
なお、上記実施の形態において、床面上を走行するキャニスタ型の電気掃除機について説明したが、例えば吸込部61に延長管128を介して吸込口本体129が接続されたアップライト型や吸込口本体129が直接接続あるいは吸込部61の本体吸込口62から直接塵埃とともに空気を吸気するハンディ型などでも利用できる。
【００７５】
また、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するなどのいずれの構成でもできる。
【００７６】
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。
【００７７】
また、第２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１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。
【００７８】
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。
【００７９】
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。
【００８０】
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。
【００８１】
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。
【００８２】
さらに、蓋体３の取手手段85はいずれの構成でもよく、また設けなくてもよい。
【００８３】
また、蓄電池18を電源に用いたが、例えば電源コードを配設して商用交流電源利用したり乾電池を用いるなどしてもよい。
【００８４】
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。
【００８５】
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。
【００８６】

BACKGROUND OF THE INVENTION
The present invention relates to a vacuum cleaner in which a cover body is provided on a case body to which a dust collecting part is attached.
[0002]
[Prior art]
As a conventional vacuum cleaner, for example, a configuration using a dust bag is known. The vacuum cleaner using the dust bag has a case body having a dust collection chamber in which the upper surface is opened and closed with a lid on the front surface of the electric blower chamber that houses the electric blower, and the dust bag is detachably mounted inside. have. Further, a suction port is provided at the front portion of the case body so that a hose is detachably connected to communicate with the inside of the dust collection bag of the dust collection chamber.
[0003]
The dust sucked together with the air through the hose is captured in a dust collection bag mounted in the dust collection chamber, and only the air is filtered and sucked from the intake port of the electric blower. In addition, a dust bag filled with dust is opened by rotating the lid to open the upper surface of the dust collection chamber, removing the dust bag from the opening and discarding it together with the dust bag. Install a dust bag in the dust chamber.
[0004]
However, in the vacuum cleaner main body using the dust collection bag, the dust collection bag collected is discarded, so that the cleaning cost cannot be reduced.
[0005]
Therefore, for example, a configuration described in Japanese Patent Publication No. 58-1936 is known.
[0006]
The vacuum cleaner described in Japanese Patent Publication No. 58-1936 includes a case body that houses an electric blower, and a dust collector that has a suction port that is detachably attached to a front side that is an intake side of the case body and that connects a hose. And a case. And the case body has opened the communicating hole connected to the inlet of an electric blower in the front. On the other hand, the dust collection case has an opening that opens to the front surface and opens to the rear surface an opening that communicates with the communication hole so as to face the front periphery of the case body. In addition, a filter body is detachably closed and attached to the opening of the dust collection case, and a dust collection chamber is defined inside. And a dust collection case is attached to the front part of a case body so that attachment or detachment is possible, and a main part case is constituted.
[0007]
In cleaning, the dust collection case is attached to the front side of the case body, and the air blower inlet of the electric blower is in communication with the dust collection chamber in the dust collection case through the filter body. After that, the electric blower is driven, and the dust sucked in with the air through the hose connected to the suction port of the dust collecting case flows into the dust collecting chamber, and the dust is separated by the filter body and only the air is filtered. The air is sucked from the intake port of the electric blower, exhausted into the case body, and further exhausted to the outside air.
[0008]
The dust collected in the dust collection chamber of the dust collection case is removed by removing the dust collection case from the case body, removing the filter body from the dust collection case, opening the opening, and inverting the opening to face downward. The structure which discharges dust from the opening part which opens is taken.
[0009]
However, in the vacuum cleaner described in the above-mentioned Japanese Patent Publication No. 58-1936, air containing dust sucked into the dust collecting case is directly filtered by the filter body. It is necessary to clean the filter body, and the cleaning work becomes complicated.
[0010]
Therefore, a configuration is conceivable in which air containing dust is swirled in a spiral, and the dust is dropped by its own gravity in the meantime to separate the dust and air.
[0011]
[Problems to be solved by the invention]
By the way, in the configuration in which the dust is dropped and separated by its own gravity, in order to efficiently separate and remove the dust, air is sucked in from the upper side of the dust collection case together with the dust and blown outward by centrifugal force. And the air needs to be discharged from above the dust collecting case on the opposite side of the dust falling direction.
[0012]
For this reason, it is necessary to form an air passage that communicates the intake side of the electric blower and the upper part of the dust collecting case in order to remove dust and extract air from above.
[0013]
This invention is made | formed in view of such a point, and it aims at providing the vacuum cleaner which can capture | acquire the dust absorbed efficiently with a simple structure.

When the furniture brush 149 is used, the tip of the gap nozzle 131 is inserted and fitted into the communication pipe portion 163 of the furniture brush 149. When the furniture brush 149 is directly attached to the tip of the hose 121 or the extension pipe 128 for cleaning, the furniture brush 149 is attached to the tip of the hose 121 or the extension pipe 128 so that the communication pipe 163 is fitted. In this state, the flange portion 166 is fitted so as to be in close contact with the distal end of the gripping portion 124 of the hose 121 and the inner peripheral surface of the distal end of the extension tube 128, and the communication tube portion 163 and the gripping portion 124 or the extension tube 128 of the hose 121 are fitted. It closes without generating a gap with the tip of the tube, and efficiently and reliably absorbs dust without leaking.
[0050]
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 handle 87, 87 of the handle means 85 or a single unit is mounted integrally when the vehicle is cleaned or carried to the storage location and stored in a predetermined position in the storage location. The 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 are different in axial direction, it is only necessary to select and hold a place 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 also be used as a handle for lifting the cleaner body 1 like the handle means 85.
[0051]
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 cleaning is finished, the locking portions 75 and 75 are operated again to release the locking. The connected state of the lid 3 to the body 2 is released, the lid 3 is rotated to open the upper surface of the dust collecting portion 9 and the upper surface of the case body 2, and the dust collecting portion 9 is held in the case by holding the handle portion 98. Remove from body 2. 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.
[0052]
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.
[0053]
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.
[0054]
In the above embodiment, 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 the axial direction in the vertical direction and opening upward, and this dust collecting Since the lid body 3 is provided so as to cover the upper part of the part 9 so that it can be opened, an air intake path 66 that opens to the upper part of the dust collecting part 9 and exhausts air is connected to the intake side of the electric blower 6. It can be provided on the lid 3 for attaching and detaching the dust portion 9 and can be simplified as compared with a configuration in which the intake passage 66 is separately provided without impairing the attaching and detaching operation of the dust collecting portion 9, improving productivity and reducing the size. Can be 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.
[0055]
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. 1 filter 26 can be easily provided with a simple configuration.
[0056]
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.
[0057]
Further, the dust collecting space 58 of the main body case 4 is detachably mounted in the intake air passage 118 between the intake side of the electric blower 6 and the main body suction port 62 and captures 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.
[0058]
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.
[0059]
In addition, a lower mounting recess 38 is provided in the case body 2 to insert and engage the lower peripheral edge of the dust collecting portion 9, 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.
[0060]
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.
[0061]
Since the upper and lower portions of the dust collecting portion 9 are covered by the mounting lower recess 38 and the mounting upper recess 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.
[0062]
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.
[0063]
Then, in order to provide the suction portion 61 in the lid body 3 that is an outer shell that can easily obtain rigidity, the hose 121 is pulled during cleaning as compared with the case where the suction portion 61 is provided directly in the dust collection portion 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.
[0064]
In addition, since the weight of the dust collector 9, the electric blower 6 and the storage battery 18 is heavy in this order, and the heaviest storage battery 18 is arranged at the approximate center of the main body case 4 located between the dust collector 9 and the electric blower 6, A stable running on the floor surface by the driven wheel 39 and the running wheels 33, 33 is obtained.
[0065]
The order of arrangement 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, from the front side in the traveling direction, the dust collector 9, the storage battery 18, the electric blower 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. When placed on the floor, the relatively heavy electric blower 6 is positioned on the lower side, so that it can be stably placed on the floor even in a standing state.
[0066]
On the other hand, since the handle means 85 is provided above the center of gravity of the vacuum cleaner body 1 and the second handle 87, 87 is branched from the first handle 86, a place where the operator is most likely to hold is selected and gripped. The main body case 4 can be easily carried stably and the cleaning workability can be improved.
[0067]

The hose 121 is connected to the vacuum cleaner main body 1 that is provided in the vacuum cleaner main body 1 with the suction means 61 formed in a substantially Y shape and the first handle 86 is provided with a suction portion 61 on the front side. Since the first handle 86 is located above the center of gravity even when the center of gravity moves to the front side from the position of the center of gravity in the case of the cleaner body 1 alone, the cleaning is performed. Even if the center of gravity moves depending on the form, it can be held at a position above the center of gravity, the cleaner body 1 can be lifted stably, and workability can be improved.
[0068]
Furthermore, since the handle means 85 is provided over substantially the entire front-rear direction of the lid body 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.
[0069]
In addition, since the handle means 85 is provided continuously to the suction portion 61, the wiring from the storage battery 18 disposed in the case body 2 is wired inside the handle means 85, and the hose 121 connected to the suction portion 61 is provided. Power can be supplied, and a separate configuration for isolating the wiring portion is not required for installation, and the configuration can be simplified to improve manufacturability and can be easily reduced in size and weight.
[0070]
Further, the handle means 85 is provided on the lid body 3 which is rotated to discharge the collected dust and opens the upper surface of the dust collecting portion 9 and the upper surface of the case body 2, so that the lid 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.
[0071]
And since the handle means 85 was continuously formed so that it might extend from the suction part 61 which protruded and formed in the cover body 3, the cover body which forms the intake path 66 which connects the dust collection part 9 to the inlet port of the electric blower 6 3 is provided with locking portions 75 and 75 respectively, and is locked by operating the pair of locking portions 75 and 75 so as to sandwich both sides of the suction portion 61 rising from the lid 3. Is released and the lid 3 can be rotated, so that the operating convex portions 79 and 79 operated in the vicinity of the grip means 85 for gripping the lid 3 to rotate are operated to release the locked state. The operability is improved and the locked state cannot be released by operating only one side. Therefore, the lock parts 75 and 75 are erroneously activated when carrying the vacuum cleaner body 1 with the handle 85. Even if the convex portions 79 and 79 are operated, the locked state is maintained unless both the operating convex portions 79 and 79 are operated. Is released can be prevented lid 3 is 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.
[0072]
On the other hand, the communication pipe part 163 of the furniture brush 149 is formed in a substantially elliptical cylindrical shape that fits the tip part of the gap nozzle 131, and when the extension pipe 128 and the tip of the grip part 124 of the hose 121 are fitted to the outer peripheral surface.
