Description

【0001】
【発明の属する技術分野】
本発明は、電気掃除機に係り、より詳しくは、絶縁不良や軸部の抜けを防止して組立性を向上させることができるコード巻き取り装置を備えた電気掃除機に関するものである。
【0002】
【従来の技術】
図4は例えば特公平7ー32743号公報に開示された従来の電気掃除機の一例を示す一部を断面にして示した平面図、図5(a),(b)は図4の要部の平面図および断面図、図6は図4の要部を一部断面にして示した平面図である。また、図7は一般的なコード巻き取り装置の一例を示す縦断面図である。
【0003】
図4において、3は電気掃除機内に配設された電動送風機で、掃除機本体1aと一体に形成した防音壁20により囲まれた状態で掃除機本体1a内に収納され、前側支持ゴム21および後側支持ゴム22によって支持されている。この電動送風機3は、図6に示すように、送風機23と整流子電動機24により構成され、整流子電動機24には整流子25、刷子26が設けられ、モーター排気口4が開口してある。
5はコードを巻き取るためのコード巻き取り装置であり、その軸13aを隔壁6に取り付けネジ27によって回転自在に取り付けてある。なお、コード巻き取り装置5の軸13aは、隔壁6と反対の位置で、支持リブ28により支持されている。
【0004】
なお、一般的なコード巻き取り装置の構成は、図7に示すように、巻枠29の中心に筒状のプラスチック部品で構成された軸13aが挿入され、ゼンマイ収納部30は固定ネジ31aにて巻枠29に固定されている。そして、軸13aの先端にある爪31によって、隔壁6とコード巻き取り装置5が一体に固定されている。この固定は、軸13aが隔壁6へ挿入されるとき、軸13aが筒状であるために、爪31は内側に変位し、挿入後は元の状態に戻ることによって行われる。こうして、コード巻き取り装置5は、隔壁6と軸13aのコード巻き取り装置固定端32によって、電気掃除機本体1aに固定されている。
【0005】
本体隔壁6は、図4に示すように、その前後を掃除機本体1aと一体に形成された支持リブ33,34により支持され、掃除機本体1a内を電動送風機3とコード巻き取り装置5とに仕切っている。なお、隔壁6には、図5に示すように、孔35が複数個設けられており、この孔35の背後にフェルト等の吸音材36が貼付けられている。37は電源供給用の接点である。38はコード巻き取り装置5を収納するコード収納空間であり、電動送風機3の排気通路9とは、この通路に面している隔壁6の孔35によって連通している。
2は電気掃除機の本体把手、39は掃除機本体1aに設けた吸気口、40は主フィルタ、41は二次フィルタ、10は排気通路9と連通している排気口である。なお、42は電源回路部品である。
【0006】
次に、電気掃除機の作用について説明する。空気は、矢印で示すように、吸込口39から掃除機本体1a内に入り、主フィルタ40を通って二次フィルタ41に至り、ここから電動送風機3内に入りその排出口4から排出され、排気通路9を通って、すなわち、電動送風機3と、コード巻き取り装置5を取り付けた隔壁6との間を通って、排気口10より掃除機本体1aの外に排出される。この際、隔壁6には複数個設けられた孔35があるので、その孔35とコード収納空間38が一種の消音器となり、排気音を低減する。孔35の裏面に吸音材36としてフェルトを貼付けることによって、さらなる吸音効果が発生する。
なお、上記のようにして空気が流れる際に、高速で回転する電動送風機3の整流子25に弾接している導電性のカーボンよりなる刷子26が磨耗して、その導電性のカーボン粉末が、モーターの排気流に乗って、モーター排気口4より排気される。
【0007】
【発明が解決しようとする課題】
上記のようなコード巻き取り装置5を備えた電気掃除機では、電動送風機3からの排気が、コード巻き取り装置5を取り付けた隔壁6の孔35から、電源供給用の接点37の近傍を通ることになる。このため、電動送風機3の導電性のカーボン粉末が、電動送風機3の排気に混ざり、電源供給用の接点37の近傍の絶縁不良を起こす恐れがあった。
また、電気掃除機は部屋間を移動したり、動きながら使用することが多く、一般的な家庭用電気製品のように据え置きされることはほとんどない。そのため、図7に示す一般的なコード巻き取り装置の場合は、長期間の使用や、持ち運び時の振動によって、軸13aの爪31が内側に変位して、隔壁6からはずれてしまう恐れがあった。
【0008】
本発明は上記のような課題を解決するためになされたもので、電動送風機から流出するカーボンによる絶縁不良を防止するとともに、軸のはずれを防止することができる電気掃除機を提供することを目的とする。
【0009】
【課題を解決するための手段】
本発明は、電動送風機と、コード巻き取り装置と、導電部材を収納する凹状の導電部材収納部を有しコード巻き取り装置に取付けられて電動送風機との仕切りをなす隔壁と、隔壁の導電部材収納部を着脱自在に覆う蓋体とを備えた掃除機本体を有し、隔壁を、軸方向に開口部を有し開口側先端に、弾性変形して内側に変位し本来の形状に戻ることで係止する係止片を有する軸部により、コード巻き取り装置に連結してコード巻き取り装置に固定するとともに、蓋体に、隔壁に係止する係止片、及び蓋体の中心軸上に係止片より長く形成され軸部の開口部に嵌入して軸抜けを防止する突起部を設けて、蓋体を隔壁に固定するようにした。これによって、電動送風機からの排気に混じった導電性のカーボン粉が導電部材収納部に侵入するのを防止して、絶縁不良を防ぐ。また、軸部先端に設けた係止部の変位を防止して、振動、衝撃からの軸の抜けを防ぐ。さらに、軸開口部への突起部の挿入を確認し、さらに隔壁への位置合わせも行う。
【0012】
【発明の実施の形態】
[実施の形態]
図1は本発明の実施の形態の一部を断面にして示した平面図、図2は図1の要部の断面図、図3は図2の分解斜視図である。図において、1は電気掃除機の掃除機本体、2は本体把手である。3は掃除機本体1内に配設した電動送風機、4は電動送風機3に設けたモーター排気口、5はコード巻き取り装置である。6は電動送風機3とコード巻き取り装置5の仕切りをなす円盤状の隔壁で、中心部に円筒状の貫通穴6cを有する凹部6aと、外周に設けたフランジ部6bとからなり、掃除機本体1に固定されてコード巻き取り装置5を支持している。7は隔壁6の凹部6aに形成された導電部材収納部で、この導電部材収納部7内にはヒューズ、電源供給用端子等が配置されている。8は隔壁6の凹部6aの上面に着脱自在に取り付けた蓋体で、プラスチックで構成された円盤状をなし、導電部材収納部7の凹部6aを閉じて閉空間化する。なお、9は排気通路、10は排気口である。
【0013】
次に、図2、図3を用いて詳述すると、11、12はコード巻き取り装置5のゼンマイ収納部及び巻枠であり、ゼンマイ収納部11はコードを巻き取る際の動力となるゼンマイを収納し、巻枠12は内部に電源供給用の接点を持つ。13はプラスチック部品からなる円筒状の軸であり、軸開口部14を有し、先端部に係止爪15を有している。
16は蓋体8を隔壁6に係止するために蓋体8の円周上に設けた固定用の係止片である。17は蓋体8から突出させた軸抜け防止用の突起部で、蓋体8の中心軸上に設けられ、係止片16よりも長く形成されており、コード巻き取り装置5の軸開口部14に挿入される。
【0014】
上記のように構成した実施の形態の作用を説明する。まず、図2、図3によって、コード巻き取り装置5の組立工程を説明する。コード巻き取り装置5を構成するゼンマイ収納部11と巻枠12の中心軸上に軸13を通し、ゼンマイ収納部11と巻枠12をネジ12aによって固定する。このとき、ゼンマイ収納部11及び巻枠12と軸13との間には隙間があり、ゼンマイ収納部11と巻枠12は軸13に対して回転自在となっている。次に、軸13の先端部を隔壁6の貫通穴6cに挿入する。その際、軸13の先端に設けた係止爪15は、軸13がプラスチック製品であるので、弾性変形して内側に変位し、特定の箇所で本来の形状に戻り、隔壁6に固定される。
【0015】
次に、蓋体8を、蓋体8から突出している係止片16によって隔壁6に取り付ける。この際、蓋体8の中央部から突出した軸抜け防止用の突起部17が、軸13の軸開口部14に挿入される。これにより、軸13の先端部に設けた係止爪15は、軸抜け防止用の突起部17があるために、コード巻き取り装置5に振動や衝撃が加わっても、物理的に内側に変位することがなくなる。この場合、蓋体8を隔壁6に取り付ける際、軸抜け防止用の突起部17が係止片16より長いため、係止片16が隔壁6に固定されるより先に、軸抜け防止用の突起部17が軸開口部14に挿入されることになる。このため、組立作業者が、確実に、軸開口部14に軸抜け防止用の突起部17が挿入されたことを確認でき、さらに、軸抜け防止用の突起部17は蓋体8の中心軸上に構成されているため、隔壁6への位置決めが容易となる。
【0016】
次に、図1によって、電気掃除機内の排気の流れを説明する。空気は、電気掃除機の吸込口から掃除機本体1内に入り、電動送風機3内を通って、矢印で示すように、モータ排気口4から排出され、排気通路9を通り、排気口10より掃除機本体3の外に排出される。この際、蓋体8によって、隔壁6の凹部6aに設けた導電部材収納部7が密閉されているため、電動送風機3の排気は、コード巻き取り装置5の内部に侵入することなく、掃除機本体1の外に排出される。こうして、電動送風機3の排気による導電性のカーボン粉の侵入を防ぐことができる。
【0017】
【発明の効果】
以上の説明から明らかなように、本発明にかかる電気掃除機は、電動送風機と、コード巻き取り装置と、導電部材を収納する凹状の導電部材収納部を有しコード巻き取り装置に取付けられて電動送風機との仕切りをなす隔壁と、隔壁の導電部材収納部を着脱自在に覆う蓋体とを備えた掃除機本体を有し、隔壁を、軸方向に開口部を有し開口側先端に、弾性変形して内側に変位し本来の形状に戻ることで係止する係止片を有する軸部により、コード巻き取り装置に連結してコード巻き取り装置に固定するとともに、蓋体に、隔壁に係止する係止片、及び蓋体の中心軸上に係止片より長く形成され軸部の開口部に嵌入して軸抜けを防止する突起部を設けて、蓋体を前記隔壁に固定するようにした。これによって、隔壁に取り付けた蓋体によって導電部材が集約している導電部材収納部が閉じられ、このため、電動送風機からの排気に混じった導電性のカーボン粉の侵入を防ぎ、電動供給用の接点付近の絶縁不良の発生を防止することができる。また、蓋体から突出した突起部をコード巻き取り装置の軸開口部に挿入して、軸部の先端に形成された係止部である係止爪の変位を物理的に防止するようにしたので、振動、衝撃による隔壁からの軸部の抜けを防止することができる。さらに、蓋体の隔壁への取付けの際に蓋体の中心軸上に位置する突起部の軸開口部への挿入を確認することができ、その上位置決めが容易となる。
