Description

【０００１】
【発明の属する技術分野】
本発明は、第１吸込具に着脱自在な第２吸込具を有する電気掃除機に関するものである。
【０００２】
【従来の技術】
図１１は、床移動型の電気掃除機の例を示すもので、この真空掃除機（電気掃除機）は吸込具に特徴を有しており、その吸込具は、延長管２１３の先端部に上下方向の回動及び回転方向の回動を可能にするボールジョイント２４０を介して中空の第２吸込具２５０が取り付けられ、この第２吸込具２５０が第１吸込具２１０の吸込口に連通する開口部２１１ａに着脱できるように構成されている。第２吸込具２５０が第１吸込具２１０に装着された状態では、延長管２１３の先端部に第１吸込具２１０が取り付けられた状態になるので、中空の第２吸込具２５０から第１吸込具２１０に通じる空気流路が形成され、第１吸込具２１０を用いた被掃除面の掃除を行うことができ、必要に応じて押圧部３２０を足で押し下げることにより第１吸込具２１０から第２吸込具２５０を離脱させることができる。この構成は第１吸込具２１０と第２吸込具２５０とを腰を屈めることなく切り換えることができ、被掃除面の掃除から階段等の狭い場所の掃除に簡単に切り換えることができる利便性を有したものとなる（例えば、特許文献１参照）。

【発明が解決しようとする課題】
しかしながら上記従来技術に係る電気掃除機では前記第１吸込具２１０に塵埃を掻き上げる回転ブラシ等を有していないため、第１吸込具２１０に第２吸込具２５０を装着して使用した場合には、集塵性能が十分でないという課題を有していた。
【０００５】
本発明は上記従来技術の課題に鑑みて創案されたもので、第１吸込具に第２吸込具を着脱自在に接続して、それぞれの吸込具を用いた掃除動作が安定して行え、かつ安全性および使用性を向上させた電気掃除機を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記目的を達成するための本発明は、吸引風を発する電動送風機を内蔵した掃除機本体と、前記電動送風機と連通し被掃除面上の塵埃を掻き上げる回転ブラシと前記回転ブラシを駆動させる駆動源とを有する第１吸込具と、前記第１吸込具に着脱自在で同じく被掃除面上の塵埃を吸引する機能を有する第２吸込具とを備え、前記第２吸込具を前記第１吸込具に装着することにより、前記第２吸込具に設けた左右一対の給電接点と、前記第１吸込具に設けた一対の受電接点とが接触することにより、前記第２吸込具から第１吸込具へ前記駆動源の電源を供給すると共に、前記第２吸込具は、前記掃除機本体と空気流路を形成する管路に接続する連結部と吸気口有する吸気ヘッドから構成され、前記連結部と前記吸気口との間に、それらを上下方向及び回転方向に回動自在に連結する回動連結手段を設け、前記第２吸込具に設けた給電接点と第１吸込具に設けた受電接点は前記回動連結手段より前方に取り付けるとともに、第１吸込具から前記第２吸込具を離脱させると、第２吸込具の回転方向の回動をロックさせる回動方向回動係止手段を有することを特徴とするもので、第２吸込具を第１吸込具に装着するだけで第１吸込具に内蔵した回転ブラシによる掃除を行うことが出来るものである。
【０００７】
【発明の実施の形態】
本発明請求項１記載の発明は、吸引風を発する電動送風機を内蔵した掃除機本体と、前記電動送風機と連通し被掃除面上の塵埃を掻き上げる回転ブラシと前記回転ブラシを駆動させる駆動源とを有する第１吸込具と、前記第１吸込具に着脱自在で同じく被掃除面上の塵埃を吸引する機能を有する第２吸込具とを備え、前記第２吸込具を前記第１吸込具に装着することにより、前記第２吸込具に設けた左右一対の給電接点と、前記第１吸込具に設けた一対の受電接点とが接触することにより、前記第２吸込具から第１吸込具へ前記駆動源の電源を供給すると共に、前記第２吸込具は、掃除機本体と空気流路を形成する管路に接続する連結部と吸気口有する吸気ヘッドから構成され、前記連結部と前記吸気口との間に、それらを上下方向及び回転方向に回動自在に連結する回動連結手段を設け、前記第２吸込具に設けた給電接点と第１吸込具に設けた受電接点は前記回動連結手段より前方に取り付けるとともに、第１吸込具から前記第２吸込具を離脱させると、第２吸込具の回転方向の回動をロックさせる回動方向回動係止手段を有することを特徴とするもので、第２吸込具に設けた給電接点と第１吸込具に設けた受電接点は、前記回動連結手段より前方の第２吸込具が回動しない位置に取り付けているので両接点の接続は確実にでき、耐久性の向上が図れる。また、連結部と吸気ヘッドとの間に、それらを上下方向及び回転方向に回動自在に連結する回動連結手段が設けられているので、手元から第１吸込具の方向転換や掃除角度が自在で第１吸込具を用いた掃除が容易となる。
【０００８】
【実施例】
以下、添付図面を参照して本発明の一実施例について説明し、本発明の理解に供する。尚、以下に示す実施例は本発明を具体化した一例であって、本発明の技術的範囲を限定するものではない。
【０００９】
本実施例は、図１に示すような床移動型の電気掃除機１及びその塵埃吸込口となる吸込具３について示すものである。この電気掃除機１は、先端に吸込具３を着脱可能に装着した延長管２は手元ハンドル（手元操作筒）４に連結され、手元ハンドル４から延出するホース６はホース継ぎ手５によって掃除機本体７に連結されている。
【００１０】
上記吸込具３は、図２（ａ）（ｂ）に示すように、前記延長管２に連結するための連結管（連結部）９に回動連結部（回動連結手段）８を介して吸気ヘッド４０が接続された第２吸込具１０を第１吸込具１１に着脱自在に装着して構成されている。第１吸込具１１に対する第２吸込具１０の着脱は、第１吸込具１１に設けられた操作レバー１３を押し下げることにより第２吸込具１０を把持する保持具１２の把持状態が解放されて第２吸込具１０を第１吸込具１１から離脱させることができ、第２吸込具１０を用いて狭い場所の掃除ができ、保持具１２内に第２吸込具１０を載せて軽く押圧することにより第２吸込具１０は第１吸込具１１に装着され、第１吸込具１１を用いて被掃除面の掃除を効率よく行なうことができる。
【００１１】
上記第２吸込具１０は、図３（ａ）（ｂ）（ｃ）に示すように、第１吸込具１１への装着方向面となる下側面は円弧状に形成され、円弧軸方向に円弧頂点部位に起毛布（起毛体）１４が貼着され、その両側に下面吸気口１５が開口し、それぞれの脇にも起毛布１４が貼着されている。また、先端側には後述する第１吸込具１１の吸込口２３に連通する先端吸気口１６が開口し、第２吸込具１０が第１吸込具１１から離脱している状態では、図４に示すように、前記先端開口部１６はバネ付勢された蓋体１８によって下面側の一部を残して閉じられる。尚、１７は後述する第１吸込具１１に設けられた回転ブラシを回転駆動する電動機２１に給電接続するための左右一対の給電接点であって、掃除機本体７からの配線リード線がホース６、手元ハンドル４、延長管２を通じて延長管２の先端に配線されており、第２吸込具１０をその連結管９で延長管２に連結するときに、連結管９に設けられた給電部１９が延長管２の先端配線に電気的接続され、給電部１９から第２吸込具１０内を配線して前記給電接点１７に配線接続されている。
【００１２】
上記起毛布１４は、シート面上に細かい毛を密集起毛させたもので、下面吸気口１５の両側を封鎖して下面吸気口１５からの吸塵能力を向上させ、第２吸込具１０の動きに応じて凹部の塵埃を掻き出し、掃除面の塵埃を下面吸気口１５に導き、掃除面を拭く作用効果を発揮すると共に、家具や掃除面を傷つけないバンパーの作用も有するものである。この第２吸込具１０に適用するのに起毛布１４が最も望ましいものであるが、同形状のブラシ、フェルト等を用いることもできる。
【００１３】
尚、本実施例の構成においては、第２吸込具１０の下面吸気口１５は２列に設けられているが、円弧の頂点部位に１列に設け、その両側に起毛布１４を配設するように構成することもできる。
【００１４】
上記第１吸込具１１は、図５に内部構成を示すように、所謂パワーノズルとして構成され、ブラシやブレードなどを回転軸に取り付けた回転ブラシ２０を電動機２１によって回転駆動し、絨毯等から塵埃を掻き出す機能を備えている。前記電動機２１への給電は、第２吸込具１０が装着されることにより、第２吸込具１０に配設された一対の給電接点１７が第１吸込具１１に配設された一対の受電接点２２に摺動接触することによりなされる。ここで第２吸込具１０を第１吸込具１１から取り外すと給電接点１７から受電接点２２が離れ、電動機２１への電源の供給がなくなり回転ブラシ２０の回転が停止する。再度第２吸込具１０を第１吸込具１１に取り付けると電動機２１への電源が供給され回転ブラシ２０は回転を開始する。このように第２吸込具１０を第１吸込具１１から取り外す動作で回転ブラシ２０の回転が止まるので次の動作にスムーズに移行できる、また取り外した第１吸込具１１の回転ブラシ２０で被掃除面を傷つけることもない。
【００１５】
また第２吸込具１０に設けた給電接点１７と第１吸込具１１に設けた受電接点２２は上記回動連結手段８より前方の第２吸込具１０が回動しない位置に取り付けているので両接点の接続は確実にでき、耐久性の向上が図れる。
【００１６】
第１吸込具１１は、前記回転ブラシ２０を収容した横長の吸込口２３を形成した幅広の吸込部２４と、その中央部分から後方に突出する走行部２５とを設けて、平面形状がＴの字状に形成され、図６に示すように、上面側に走行部２５の後方端から吸込部２４にかけて第２吸込具収納凹部２６が形成されている。第２吸込具収納凹部２６内の前方側には前記吸込口２３に連通する連通口２７が開口されており、第２吸込具収納凹部２６に第２吸込具１０を装着すると、第２吸込具１０に形成された先端吸気口１６の蓋体１８は開き、前記連通口２７と先端吸気口１６との間が連通し、掃除機本体７への空気流路が形成される。
【００１７】
図７は、第１吸込具１１に第２吸込具１０を装着した状態を示す断面図で、第１吸込具１１に第２吸込具１０が装着されると、第２吸込具収納凹部２６内の前方側から後方側に向けて突出する開閉操作リブ（先端吸気口開閉手段）２８が第２吸込具１０の先端吸気口１６をバネ付勢によって部分的に閉じていた蓋体１８を回動させ、図示するようにバネ付勢に抗して蓋体１８を開き、先端吸気口１６を全開状態にして、吸込口２３から連結管９に至る空気流路を形成する。また、第２吸込具１０の下面吸気口１５は第２吸込具収納凹部２６の底面によって塞がれるので、第２吸込具１０を第１吸込具１１に装着した状態では、吸込口２３からの吸気のみとなり、第１吸込具１１による吸塵能力が損なわれない。
【００１８】
図６に示すように、第１吸込具１１に形成された第２吸込具収納凹部２６は、第２吸込具１０の高さ方向寸法と略同等の深さに形成されており、これに第２吸込具１０を収容すると、図２（ｂ）及び図７に示すように、第１吸込具１１の上面から第２吸込具１０が少し出るのみで、家具の下に空いた空間などに第１吸込具１１を挿入できる扁平な第１吸込具１１に構成することができる。また、第１吸込具１１の高さは、図２に示すように第２吸込具収納凹部２６の両側に小回り車輪３６を配設したことによっても高さ減少の効果が得られている。
【００１９】
第１吸込具１１に設けられた操作レバー１３を下方に押し下げる（足先で踏む）と、第２吸込具１０を第１吸込具１１から離脱させることができる。図４に示すように、先端吸気口１６に設けられた蓋体１８は前記開閉操作リブ（先端吸気口開閉手段）２８による押圧がなくなるので、バネ付勢によって蓋体１８は図示するように先端吸気口１６を閉じる。このとき、蓋体１８の上下方向寸法を先端吸気口１６の開口高さ寸法より小さくしておくことにより、下方を空けた状態で先端吸気口１６を部分的に閉じた状態が得られる。また、下面吸気口１５は開放状態になるので、先端吸気口１６の下方と複数の下面吸気口１５から連結管９に至る空気流路が形成され、第２吸込具１０による集塵機能が得られる。
【００２０】
次に、第１吸込具１１に対する第２吸込具１０の着脱構造について、図８及び図９を参照して説明する。
【００２１】
図８及び図９において、第１吸込具１１に形成された第２吸込具収納凹部２６内には、その断面形状に沿うように保持具（第２吸込具着脱手段）１２が配設されている。保持具１２はその中央のヒンジ部分で左右一対に接続され、図８に示す解放状態と、図９に示す把持状態とに切り換え操作することができ、その操作は前記操作レバー１３の押し下げにより、図８に示す解放状態、即ち第２吸込具１０の離脱状態とし、保持具１２内に第２吸込具１０を押し入れることにより、図９に示す把持状態、即ち第２吸込具１０の装着状態とすることができる。
【００２２】
図８に示す離脱状態では、保持具１２は中央のヒンジ部分から左右に展開した状態にあり、保持具１２内に第２吸込具１０を押し入れると、ヒンジ部分の中央部に配設された押圧部材２９が第２吸込具１０の円弧側面頂点部位の起毛布１４を前後に分割配置した間（図３参照）で押圧されて下がるので、保持具１２は第２吸込具収納凹部２６の底面側に下り、図９に示すように、第２吸込具１０の吸気ヘッド４０部位を包み込むように把持する。前記押圧部材２９の下降と共に、それに連結された駆動部材３２が支持部材３１に軸支されたロッド３０の一端を押し下げるので、ロッド３０の他端に設けられた操作レバー１３は、図９に示すように上昇位置になる。上記押圧部材２９、ロッド３０、支持部材３１、駆動部材３２は、保持具１２と共に第２吸込具着脱手段３８を構成する。
【００２３】
この保持具１２による第２吸込具１０の装着状態をより確実にするためには、図示するように第２吸込具１０の両側面に外方に付勢された係止ピン３３を設け、これに対応して保持具１２に係止凹部３４を形成すると、第２吸込具１０が保持具１２内に押し入れられたとき、係止ピン３３が係止凹部３４内に嵌り込み、第１吸込具１１に対する第２吸込具の安定した装着状態が得られる。尚、保持具１２には、第２吸込具１０に設けられた起毛布１４を収容するための起毛布収納凹部３５が形成され、第２吸込具１０の装着状態で起毛布１４が押し潰されてその機能が損なわれることを防止している。
【００２４】
図９に示す第１吸込具１１に対する第２吸込具１０の装着状態から第２吸込具１０を離脱させるには、上昇位置にある操作レバー１３を押し下げると、ロッド３０が支持部材３１を支点として回動し、駆動部材３２により保持具１２のヒンジ部分を押し上げるので、保持具１２が開くと同時に押圧部材２９によって第２吸込具１０が押し上げられ、第２吸込具１０を第１吸込具１１から離脱させることができる。
【００２５】
前述したように、第２吸込具１０には吸気ヘッド４０と連結管９との間を回転方向に回動自在に連結する回動連結部８が設けられており、図２及び図７に示すように、第２吸込具１０が第１吸込具１１に装着された状態では、図１に示すように連結管９に延長管２を介して連結された手元ハンドル４の上げ下げに対応して、連結管９は回動連結部８に対し上下回動し、手元ハンドル４を回動させる動き、即ち第１吸込具１１の進路方向を左右いずれかの方向に変更するハンドル操作がなされるときには、進路方向に手元ハンドル４を回動させる動きが自然になされるので、回動連結部８に回動力が加わると、第１吸込具１１の後方側に回動連結部８があるため、軸の回転方向に第１吸込具１１が回動する動きが働き、スムーズに第１吸込具１１の進路変更がなされる。
【００２６】
第２吸込具１０を第１吸込具１１から離脱させた状態では、第２吸込具１０が回転方向に動くと扱い難くなるので、回動連結部８の回転方向の動きをロックする回転方向回動係止手段を設けることができる。前記回転方向回動係止手段は、バネ付勢された係止部材を設け、第２吸込具１０が第１吸込具１１に装着された状態では、第１吸込具１１側に設けた係止解除手段によりバネ付勢に抗して係止部材を回転方向回動の係止状態から外すように構成すると、第２吸込具１０が第１吸込具１１に装着された状態では回転方向回動係止手段は機能しないため、第１吸込具１１の上下及び回転方向の自在回動が可能となり、第２吸込具１０を第１吸込具１１から離脱させると回転方向回動係止手段が機能して第２吸込具１０の回転方向の回動をロックさせることができる。
【００２７】
上記構成になる吸込具３を用いた電気掃除機１は、第２吸込具１０を第１吸込具１１に装着した状態にすると、幅広の第１吸込具１１により一般的な電気掃除機と同様に被掃除面の掃除を効率よく行なうことができ、第１吸込具１１が入らない狭い場所や階段などを掃除する必要に応じて操作レバー１３を足踏みすると、腰を屈めることなく第１吸込具１１から第２吸込具１０を離脱させることができ、第２吸込具１０を用いた掃除ができるので、先端ノズルを付け替える面倒な作業は解消される。また、第２吸込具１０を離脱させた第１吸込具１１は被掃除面にあるので、任意に第１吸込具１１に第２吸込具１０を押し入れると即座に床掃除に変更することができる。
【００２８】
第２吸込具１０を第１吸込具１１から離脱させた状態で使用するとき、下面吸気口１５の形成面が円弧状に形成されていることにより、図１０に略図示するように、掃除面に対して自由な角度状態が得られ、特に、図１０（ｂ）に示すように、壁面や家具の立ち上がりのコーナー部分にも下面吸気口１５の吸気が作用してコーナー部分の塵埃を集塵除去することができる。また、第２吸込具１０の先端吸気口１６は、前述したように第１吸込具１１からの離脱時に下側面側を残して蓋体１８によって閉じられるので先端吸気口１６の開口面積が縮小する結果、吸気流速が増加し、掃除面に近い側で開口するので、第２吸込具１０は先端側からの集塵効果も得られ、より広範囲の掃除が可能となる。尚、先端吸気口１６は蓋体１８により開口面積全体を閉じるように構成して下面吸気口１５からの吸気能力を増加させることもできる。
【００２９】
また、第２吸込具１０を手元ハンドル４の操作により第１吸込具１１に装着するとき、第１吸込具１１の後方側に小回り車輪３６が存在し、この小回り車輪３６を支点として第１吸込具１１が立ち上がったり、前方に走行してしまうことがないように、第２吸込具１０に設けられた回動連結部８の回動支点より後方に小回り車輪３６が配設されている。
【００３０】
また、手元ハンドル付きの小型掃除機本体に短い管路で吸込具を取り付けたハンドクリーナと称される電気掃除機に本実施例の構成になる吸込具３を適用することもでき、ハンドクリーナとしての機能を向上させることができる。
【００３１】
【発明の効果】
以上説明した通り本発明によれば、第１吸込具に第２吸込具を着脱自在に接続して、それぞれの吸込具を用いた掃除動作が安定して行え、かつ安全性および使用性を向上させた電気掃除機を提供できる。
