Description

【０００１】
【産業上の利用分野】
本発明は、電気掃除機に係わり、特にそのホースの改良に関する。
【０００２】
【従来の技術】
従来の技術を図１０乃至図１１に基づいて説明する。従来、図に示す如く、電気掃除機のホース21は、可撓性の蛇腹状ホース22の両端部に各々接続部材23、24を接続し、本体側接続部材23を介して掃除機本体25の吸込口26に接続するようになっているが、図１０に示す掃除状態において、掃除機本体25が敷居等の段差に引っ掛かった際等に、ホース21を引っ張って掃除機本体25を引き寄せると、蛇腹状ホース22は接続部材23、24との重合部分端部、即ち、接続部材23、24端部において多大な負荷を受けて急激に屈曲し、このような動作を繰り替えると蛇腹状ホース22が破損する恐れがある。
【０００３】
また、使用者がホース21の手元側を持ち上げると、蛇腹状ホース22が下方に下がるため、蛇腹状ホース22の手元側における蛇腹状ホース22と手元側接続部材24との重合部分近傍が急角度に曲げられると共に、掃除中の吸込具27の前後移動において、吸込具27を使用者側に引き寄せた際には、蛇腹状ホース22の手元側重合部分近傍がさらに急角度に曲げられる。蛇腹状ホース22と接続部材24との重合部分を被うカバー28の寸法が蛇腹状ホース22と接続部材24との重合代と略等しいため、蛇腹状ホース22が接続部材24の端部を支点として急激に曲がり、蛇腹状ホース22の手元側重合部分近傍が疲労して破れる問題がある。
【０００４】
さらに、近年、電気掃除機の収納時には、図11に示すごとく、掃除機本体25を立てた状態に保持し、ホース21及び延長パイプ29等を掃除機本体25に接続したまま延長パイプ29に設けた係止部を掃除機本体25に係止して収納することが行われているが、この収納状態では、蛇腹状ホース22の手元側重合部分近傍が急角度に曲げられた上体に保持されるため、手元側重合部分近傍が疲労して破損する問題がある。
【０００５】
【発明が解決しようとする課題】
本発明は、上記欠点に鑑みなされたもので、ホースの破損を防止することのできる電気掃除機を提供することを課題とする。
【０００６】
【課題を解決するための手段】
本発明の第１の手段は、前方に吸込口を形成した掃除機本体と、一端を前記吸込口に着脱自在に接続すると共に他端に延長パイプの一端を接続する可撓性ホースと、前記延長パイプの他端側に取り付けられる床用吸込具とを備え、前記可撓性ホースは、吸込口に接続される第１接続部材と、前記延長パイプに接続される第２接続部材と、前記第１、第２接続部材間を連結する可撓性ホース部材と、前記第１接続部材に取り付けられ、前記ホース部材と第１接続部材との重合部分を被う第１カバーと、前記第２接続部材に取り付けられ、前記ホース部材と第２接続部材との重合部分を被う第２カバーとから構成すると共に、前記第１カバーのホース部材側にホース部材外周を被う蛇腹状のプロテクターを装着したことを特徴とする。
【０００７】
本発明の第１の手段によれば、掃除時に、掃除機本体が敷居等の段差に引っ掛かった状態で、掃除機本体の進行方向以外の方向へホースを引っ張って掃除機本体を引き寄せた場合、ホースの掃除機本体側である第１接続部材とホース部材の重合部分において、ホース部材が第１接続部材端部から急角度に曲がろうとするが、プロテクターがホース部材の補強となり、ホース部材の湾曲半径が大きくなってホース部材の疲労が小さくなり、耐久性が向上すると共に、ホース部材が折れ曲がって空気の流路が狭まるのが防止される。また、プロテクターは蛇腹状に形成しているので、屈曲に対する耐久性及び強度が向上し、長期にわたってホース部材が保護されると共に、屈曲時に、プロテクターに皺等が生じることがなく、外観が向上する。
【００１２】
本発明の第２の手段は、前方に吸込口を形成した掃除機本体と、一端を前記吸込口に着脱自在に接続すると共に他端に延長パイプの一端を接続する可撓性ホースと、前記延長パイプの他端側に取り付けられる床用吸込具とを備え、前記可撓性ホースは、吸込口に接続される第１接続部材と、前記延長パイプに接続される第２接続部材と、前記第１、第２接続部材間を連結する蛇腹状のホース部材と、前記第１接続部材に取り付けられ、前記ホース部材と第１接続部材との重合部分を被う第１カバーと、前記第２接続部材に取り付けられ、前記ホース部材と第２接続部材との重合部分を被う第２カバーとから構成すると共に、前記第１カバー近傍のホース部材外周を被う蛇腹状のプロテクターを設け、該プロテクターの蛇腹の凹凸の旋回方向を、ホース部材の蛇腹の凹凸の旋回方向と交差するように形成したことを特徴とする。
【００１３】
本発明の第２の手段によれば、掃除時に、掃除機本体が敷居等の段差に引っ掛かった状態で、掃除機本体の進行方向以外の方向へホースを引っ張って掃除機本体を引き寄せた場合に、ホースの掃除機本体側において、ホース部材が第１接続部材端部から急角度に曲がろうとするが、プロテクターがホース部材の補強となって、ホース部材が緩やかな曲がりとなり、ホース部材が保護されると共に、ホース部材が折れ曲がって空気の流路が狭まるのが防止される。また、プロテクターの蛇腹の凹凸の旋回方向を、ホース部材の蛇腹の凹凸の旋回方向と交差するように形成したので、ホース部材が湾曲した際に、ホース部材の凹凸にプロテクターの凹凸が噛み込むことがなく、ホース部材の湾曲性を損なうことがない。
【００１４】
本発明の第３の手段は、前方に吸込口を形成した掃除機本体と、一端を前記吸込口に着脱自在に接続すると共に他端に延長パイプの一端を接続する可撓性ホースと、前記延長パイプの他端側に取り付けられる床用吸込具とを備え、前記可撓性ホースは、吸込口に接続される第１接続部材と、前記延長パイプに接続される第２接続部材と、前記第１、第２接続部材間を連結する蛇腹状のホース部材と、前記第１接続部材に取り付けられ、前記ホース部材と第１接続部材との重合部分を被う第１カバーと、前記第２接続部材に取り付けられ、前記ホース部材と第２接続部材との重合部分を被う第２カバーとから構成すると共に、前記第１カバー近傍のホース部材外周を被う蛇腹状のプロテクターを設け、該プロテクターの蛇腹の凹凸の旋回方向を、ホース部材の蛇腹の凹凸の旋回方向と一致するように形成したことを特徴とする。
【００１５】
本発明の第３の手段によれば、掃除時に、掃除機本体が敷居等の段差に引っ掛かった状態で、掃除機本体の進行方向以外の方向へホースを引っ張って掃除機本体を引き寄せた場合に、ホースの掃除機本体側において、ホース部材が第１接続部材端部から急角度に曲がろうとするが、プロテクターがホース部材の補強となって、ホース部材が緩やかな曲がりとなり、ホース部材が保護されると共に、ホース部材が折れ曲がって空気の流路が狭まるのが防止される。また、プロテクターの蛇腹の凹凸の旋回方向を、ホース部材の蛇腹の凹凸の旋回方向と一致するように形成したので、ホース部材の曲率が大きくなり、ホース部材の耐久性が向上する。
【００１６】
本発明の第４の手段は、前方に吸込口を形成した掃除機本体と、一端を前記吸込口に着脱自在に接続すると共に他端に延長パイプの一端を接続する可撓性ホースと、前記延長パイプの他端側に取り付けられる床用吸込具とを備え、前記可撓性ホースは、吸込口に接続される第１接続部材と、前記延長パイプに接続される第２接続部材と、前記第１、第２接続部材間を連結するホース部材と、前記第１接続部材に取り付けられ、前記ホース部材と第１接続部材との重合部分を被う第１カバーと、前記第２接続部材に取り付けられ、前記ホース部材と第２接続部材との重合部分を被う第２カバーとから構成すると共に、前記第１カバー近傍のホース部材外周を被う蛇腹状のプロテクターを設け、該プロテクターの蛇腹の凹凸のピッチを、凹凸の高さ寸法より大きくしたことを特徴とする。
【００１７】
本発明の第４の手段によれば、掃除時に、掃除機本体が敷居等の段差に引っ掛かった状態で、掃除機本体の進行方向以外の方向へホースを引っ張って掃除機本体を引き寄せた場合に、ホースの掃除機本体側において、ホース部材が第１接続部材端部から急角度に曲がろうとするが、プロテクターがホース部材の補強となって、ホース部材が緩やかな曲がりとなり、ホース部材が保護されると共に、ホース部材が折れ曲がって空気の流路が狭まるのが防止される。また、プロテクターの蛇腹の凹凸のピッチを、凹凸の高さ寸法より大きくしたので、プロテクターを装着してもホース部材の湾曲性が大きく損なわれることがなく、掃除作業性が低下することがない。
【００１８】
本発明の第５の手段は、前方に吸込口を形成した掃除機本体と、一端を前記吸込口に着脱自在に接続すると共に他端に延長パイプの一端を接続する可撓性ホースと、前記延長パイプの他端側に取り付けられる床用吸込具とを備え、前記可撓性ホースは、吸込口に接続される第１接続部材と、前記延長パイプに接続される第２接続部材と、前記第１、第２接続部材間を連結するホース部材と、前記第１接続部材に取り付けられ、前記ホース部材と第１接続部材との重合部分を被う第１カバーと、前記第２接続部材に取り付けられ、前記ホース部材と第２接続部材との重合部分を被う第２カバーとから構成すると共に、前記第１カバー近傍のホース部材外周を被う蛇腹状のプロテクターを設け、該プロテクターの蛇腹の凹凸の高さ寸法を、プロテクター内面とホース部材との隙間より大きく形成したことを特徴とする。
【００１９】
本発明の第５の手段によれば、掃除機本体を起立状態に収納した際、ホースの手元部分である第２接続部材とホース部材の重合部分において、ホース部材が第２接続部材端部から急角度に曲がろうとするが、プロテクターがホース部材の補強となり、ホース部材が保護される。プロテクターの長さを、ホース部材の直径状とすることによりホース部材の湾曲半径が大きくなってホース部材の疲労が小さくなり、耐久性が向上すると共に、ホース部材が折れ曲がって空気の流路が狭まるのが防止される。また、プロテクターの蛇腹の凹凸の高さ寸法を、プロテクター内面とホース部材との隙間より大きく形成したので、わずかな湾曲であってもプロテクターがホース部材とともに湾曲し、ホース部材の耐久性をより向上する。
【００２０】
本発明の第６の手段は、前方に吸込口を形成した掃除機本体と、一端を前記吸込口に着脱自在に接続すると共に他端に延長パイプの一端を接続する可撓性ホースと、前記延長パイプの他端側に取り付けられる床用吸込具とを備え、前記可撓性ホースは、吸込口に接続される第１接続部材と、前記延長パイプに接続される第２接続部材と、前記第１、第２接続部材間を連結するホース部材と、前記第１接続部材に取り付けられ、前記ホース部材と第１接続部材との重合部分を被う第１カバーと、前記第２接続部材に取り付けられ、前記ホース部材と第２接続部材との重合部分を被う第２カバーとから構成すると共に、前記第１カバー近傍のホース部材外周を被う蛇腹状のプロテクターを設け、該プロテクターの蛇腹の凹凸のピッチを、第１カバーから離れるにしたがって漸次狭くなるように形成したことを特徴とする。
【００２１】
本発明の第６の手段によれば、掃除機本体を起立状態に収納した際、ホースの手元部分である第２接続部材とホース部材の重合部分において、ホース部材が第２接続部材端部から急角度に曲がろうとするが、プロテクターがホース部材の補強となり、ホース部材が保護される。プロテクターの長さを、ホース部材の直径状とすることによりホース部材の湾曲半径が大きくなってホース部材の疲労が小さくなり、耐久性が向上すると共に、ホース部材が折れ曲がって空気の流路が狭まるのが防止される。また、プロテクターの蛇腹の凹凸のピッチを、第１カバーから離れるにしたがって漸次狭くなるように形成したので、プロテクターの可撓性が第１カバーから離れるにしたがって漸次大きくなり、プロテクター端部においてホース部材が急角度に曲がるのが防止され、ホース部材の耐久性が向上する。
【００２２】
本発明の第７の手段は、前方に吸込口を形成した掃除機本体と、一端を前記吸込口に着脱自在に接続すると共に他端に延長パイプの一端を接続する可撓性ホースと、前記延長パイプの他端側に取り付けられる床用吸込具とを備え、前記可撓性ホースは、吸込口に接続される第１接続部材と、前記延長パイプに接続される第２接続部材と、前記第１、第２接続部材間を連結するホース部材と、前記第１接続部材に取り付けられ、前記ホース部材と第１接続部材との重合部分を被う第１カバーと、前記第２接続部材に取り付けられ、前記ホース部材と第２接続部材との重合部分を被う第２カバーとから構成すると共に、前記第１カバー近傍のホース部材外周を被う蛇腹状のプロテクターを設け、該プロテクターの蛇腹の凹凸の高さ寸法を、第１カバーから離れるにしたがって漸次高くなるように形成したことを特徴とする。
【００２３】

３は一端が前記掃除機本体１の吸込口２に接続されると共に、他端に後述する延長パイプ10を接続する可撓性ホースで、蛇腹状のホース部材４と、該ホース部材４の一端に接続される後述の本体側接続部材８、ホース部材４の他端に接続される後述の手元側接続部材９とを有している。前記ホース部材４は、長手方向に複数の突条５、５、５、６、６を形成して短手方向断面において複数の凹凸を有する高い復元性及び柔軟性を有する合成樹脂性、本実施形態では、ＬＬＰＥを含有したＥＶＡ製のシートを、螺旋状に巻回して螺旋状の突条を有する蛇腹状に形成されており、前記突条６、６には、後述する床用吸込具17の図示しない回転ブラシ駆動用電動機に給電する一対の導電線７、７が配設されている。
【００４４】
８は前記ホース部材４の一端、即ち、掃除機本体１の吸込口２に着脱自在に装着される本体側接続部材で、該本体側接続部材８に設けられた図示しないフックにより吸込口２からの抜け止めを行っている。尚、本体側接続部材８のホース部材４との接続構造は、後述の手元側接続部材９と同様の構造であるので、手元側接続部材９の説明をもって代用する。
【００４５】
９は前記ホース部材４の他端、即ち、延長パイプ10接続側に取り付けられる手元側接続部材、11は前記手元側接続部材９の、ホース部材４接続側端部近傍の外周面に形成された複数の突部で、手元側接続部材９のホース部材接続側端部に、ホース部材４を、その突条の螺旋に沿って捩りながら挿入することにより、突部11がホース部材４の突条６、６、６に噛み込み、ホース部材４を手元側接続部材９に固定するようになっている。12は前記手元側接続部材９の外周面に形成された係止リブで、後述するカバー13が係合するようになっている。
【００４６】
13は一端部に前記手元側接続部材９の係止リブ12に係合する図示しない係合部を有し、係止リブ12と係合部との係合により手元側接続部材９に装着される樹脂製のカバーで、手元側接続部材９とホース部材４との重合部分を、ホース部材４との間に間隙を有して被うようになっている。14は前記カバー13の他端部に形成された係合部となる複数の係合孔で、後述するプロテクター15の係合爪16に係合するようになっており、係合孔14はカバー13を手元側接続部材９に装着した状態で、手元側接続部材９に重合する位置に形成されている。前記カバー13はＡＢＳ、ポリプロピレン等の合成樹脂にて形成することが望ましく、剛性が高く、且つ薬品等による化学変化が起こりにくく、且つ熱に強いポリプロピレン樹脂が最適である。
【００４７】
15は前記カバー13の係合孔14に係合する係合爪16を有するプロテクターで、外径をカバー13内径と略同径に形成すると共に、内径をホース部材４外径より少許大径に形成し、ホース部材４とカバー13との間に挿入し、係合爪16をカバー13の係合孔14に係合して装着されており、装着状態で、係合爪16が手元側接続部材９に重合するようになっている。前記プロテクター15は、カバー13より低い硬度と高い弾力性を有し、且つホース部材４より高い硬度と低い弾力性を有する可撓性材料、例えば、ＴＰＥ等にて形成している。
【００４８】
17は前記延長パイプ10に着脱自在に装着される床用吸込具で、図示しない回転ブラシを駆動する電動機を内蔵している。
【００４９】
而して、手元側接続部材９のホース部材４接続側端部に、ホース部材４を挿入し、手元側接続部材９の突部５に、ホース部材４の突条６、６、６の螺旋を沿わせてホース部材４を捩りながら手元側接続部材９に装着する。そして、手元側接続部材９とホース部材４との重合部分を被うようにカバー13を装着し、カバー13を手元側接続部材９の係止リブ12に係合して固定する。その後、プロテクター15の一端側をホース部材４とカバー13との間に挿入し、プロテクター15の係合爪16をカバー13に形成した係合孔14に係合する。
【００５０】
プロテクター15は係合爪16をカバー13の係合孔14に係合するだけで装着でき、装着作業性を向上することができる。また、プロテクター15の係合爪16は、カバー13の内面側から係合孔14に係合するので、係合爪14に外力が加わりにくく、係合爪16が係合孔14から容易に外れることがない。さらに、プロテクター15の係合爪16は、手元側接続部材９の外側に位置するので、係合爪16に内側方向に外力が加わっても、係合爪16の内側への変形が阻止され、プロテクター15が容易にカバー13から離脱することがない。
【００５１】
掃除する際は、手元側接続部材９近傍を把持して床用吸込具17を前後に摺動する。この手元側接続部材９を把持して持ち上げた状態では、ホース部材４が自重により下方に下がるため、ホース部材４が手元側接続部材９端部近傍から急角度に曲がろうとするが、ホース部材４より強い硬度を有するプロテクター15がホース部材４を補強してホース部材４が急角度に曲がるのを防止し、ホース部材４の破損を防止する。
【００５２】
また、ホース部材４と本体側接続部材８との重合部分においても、上記手元側接続部材９とホース部材４との重合部分と同様の構造であるため、掃除機本体１が敷居等の段差に引っ掛かった状態で、掃除機本体１の進行方向以外の方向へホース３を引っ張って掃除機本体１を引き寄せた場合でも、プロテクター15によってホース部材４が本体側接続部材８の端部を支点に急角度に折れ曲がるのが抑制され、ホース部材４の破損が防止される。
【００５３】
プロテクター15は蛇腹状に形成されているので、屈曲に対する耐久性及び強度が向上し、長期間にわたってホース部材４を保護することができると共に、屈曲時に、プロテクター15に皺等が生じることがなく、外観を向上することができる。また、プロテクター15の蛇腹の凹凸のピッチを、凹凸の高さ寸法より大きくしたので、プロテクター15を装着してもホース部材４の湾曲性が大きく損なわれることがなく、掃除作業性が低下することがない。さらに、プロテクター15の蛇腹の凹凸の高さ寸法を、プロテクター15内面とホース部材４との隙間より大きく形成し、プロテクター15内面とホース部材４外面とを近接させたので、プロテクター15が確実にホース部材４とともに湾曲し、ホース部材４をより確実に保護することができる。
【００５４】
また、プロテクター15の蛇腹の凹凸の螺旋方向がホース部材４の蛇腹の凹凸の螺旋方向と交差するよう構成したので、ホース部材４を湾曲してもプロテクター15の蛇腹の凹凸がホース部材４の蛇腹の凹凸に噛み込まれることがなく、ホース部材４の湾曲性を損なうことがない。
【００５５】
収納する際には、図７に示すごとく、掃除機本体１を起立状態とし、可撓性ホース３、延長パイプ10、床用吸込具17を掃除機本体１に接続した状態で、延長パイプ10に設けた図示しない係合手段を掃除機本体１の係合部に係合し、延長パイプ10を掃除機本体１に係止する。
【００５６】
ホース部材４は、誤ってホース部材４を踏みつけても復元するように復元性及び弾力性の高い材料、本実施形態ではＬＬＰＥを含有したＥＶＡを用いているが、この材料は比較的耐熱性が低いため、収納時に、掃除機本体１を暖房機の近傍や、夏季などの気温の高いときに直射日光が当る場所に配置した場合などには、ホース部材４が熱の影響により柔らかくなり、自重により変形してつぶれ、温度が低下すると、ホース部材４が再び元の固さに戻ってその変形した状態を維持する問題があるが、プロテクター15はホース部材４より耐熱性の高い材料にて形成しているので、温度が高い状態でもプロテクター15によりホース部材４が急激に屈曲することなく、空気の流路が狭まるのを防止することができる。
【００５７】
尚、上述した実施形態では、プロテクター15の蛇腹の凹凸のピッチを均一に形成したが、プロテクター15の蛇腹の凹凸のピッチを、カバー13から離れるにしたがって狭くなるように形成して、カバー13から離れるにしたがってプロテクター15の剛性が弱くなるように構成してもよい。この構成とすることにより、プロテクター15端部においてホース部材４が急激に曲がるのを防止することができる。
【００５８】
また、プロテクター15の蛇腹の凹凸の高さを、カバー４から離れるにしたがって低くなるように形成して、カバー４から離れるにしたがってプロテクター15の剛性が弱くなるように構成してもよい。
【００５９】
さらに、図８及び図９に示す如く、プロテクター15の蛇腹の凹凸の旋回方向を、ホース部材４の蛇腹の旋回方向と一致するように構成してもよい。この構成では、ホース部材４が湾曲すると、ホース部材４の蛇腹の凹凸とプロテクター15の蛇腹の凹凸が噛み合って、ホース部材４の曲率が大きくなり、ホース部材４の耐久性が向上する。

DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of the present invention will be described in detail below with reference to FIGS. 1 and 7.
[0042]
1 is a vacuum cleaner body, which has a dust collection chamber in the front and a blower chamber (both not shown) with a built-in electric blower in the rear, and a suction port communicating with the dust collection chamber in the front of the vacuum cleaner body 1 2 is formed.
[0043]
Reference numeral 3 denotes a flexible hose having one end connected to the suction port 2 of the cleaner body 1 and an extension pipe 10 to be described later to the other end. The bellows-like hose member 4 and one end of the hose member 4 And a later-described main-side connection member 9 connected to the other end of the hose member 4. The hose member 4 is formed of a plurality of protrusions 5, 5, 5, 6, 6 in the longitudinal direction and has a plurality of projections and depressions in the short-side cross section, and has a high resilience and flexibility, and this embodiment In the embodiment, an EVA sheet containing LLPE is spirally wound to form a bellows having spiral ridges, and the ridges 6 and 6 have floor suction tools 17 described later. A pair of conductive wires 7 for supplying power to a rotating brush driving motor (not shown) is provided.
[0044]
Reference numeral 8 denotes a main body side connecting member that is detachably attached to one end of the hose member 4, that is, the suction port 2 of the cleaner main body 1, and is connected from the suction port 2 by a hook (not shown) provided in the main body side connecting member 8. I'm keeping it from coming off. In addition, since the connection structure with the hose member 4 of the main body side connection member 8 is the same structure as the below-mentioned hand side connection member 9, it substitutes with description of the hand side connection member 9.
[0045]
9 is the other end of the hose member 4, that is, a proximal side connecting member attached to the extension pipe 10 connection side, and 11 is formed on the outer peripheral surface of the proximal side connecting member 9 in the vicinity of the end of the hose member 4 connection side. By inserting the hose member 4 into the hose member connection side end of the proximal connection member 9 while twisting it along the spiral of the protrusion, the protrusion 11 becomes the protrusion of the hose member 4. 6, 6, and 6, and the hose member 4 is fixed to the proximal connection member 9. Reference numeral 12 denotes a locking rib formed on the outer peripheral surface of the proximal side connecting member 9 so that a cover 13 which will be described later is engaged.
[0046]
13 has an engaging portion (not shown) that engages with the locking rib 12 of the proximal connection member 9 at one end, and is attached to the proximal connection member 9 by engagement of the locking rib 12 and the engagement portion. A resin cover that covers the overlapping portion of the proximal connection member 9 and the hose member 4 with a gap between the hose member 4 and the hose member 4. Reference numeral 14 denotes a plurality of engaging holes which are engaging portions formed at the other end of the cover 13, and engages with engaging claws 16 of a protector 15 which will be described later. In a state in which 13 is attached to the proximal side connecting member 9, it is formed at a position overlapping with the proximal side connecting member 9. The cover 13 is preferably formed of a synthetic resin such as ABS or polypropylene, and is most preferably a polypropylene resin having high rigidity and being unlikely to undergo chemical changes due to chemicals or the like and being resistant to heat.
[0047]
Reference numeral 15 denotes a protector having an engaging claw 16 that engages with the engaging hole 14 of the cover 13, and the outer diameter is formed substantially the same as the inner diameter of the cover 13, and the inner diameter is smaller than the outer diameter of the hose member 4. Formed, inserted between the hose member 4 and the cover 13, and engaged with the engaging claw 16 engaged with the engaging hole 14 of the cover 13, and the engaging claw 16 is connected to the proximal side in the mounted state. The member 9 is superposed. The protector 15 is formed of a flexible material, such as TPE, having lower hardness and higher elasticity than the cover 13 and higher hardness and lower elasticity than the hose member 4.
[0048]
Reference numeral 17 denotes a floor suction tool that is detachably attached to the extension pipe 10 and has a built-in electric motor that drives a rotating brush (not shown).
[0049]
Thus, the hose member 4 is inserted into the hose member 4 connection side end of the proximal side connection member 9, and the protrusions 6, 6, 6 of the hose member 4 are inserted into the protrusion 5 of the proximal side connection member 9. Attaching the hose member 4 to the proximal connection member 9 while twisting the hose member 4. Then, the cover 13 is mounted so as to cover the overlapping portion of the proximal side connecting member 9 and the hose member 4, and the cover 13 is engaged and fixed to the locking rib 12 of the proximal side connecting member 9. Thereafter, one end side of the protector 15 is inserted between the hose member 4 and the cover 13, and the engaging claw 16 of the protector 15 is engaged with the engaging hole 14 formed in the cover 13.
[0050]
The protector 15 can be mounted simply by engaging the engaging claw 16 with the engaging hole 14 of the cover 13, and the mounting workability can be improved. Further, since the engaging claw 16 of the protector 15 engages with the engaging hole 14 from the inner surface side of the cover 13, it is difficult for external force to be applied to the engaging claw 14, and the engaging claw 16 is easily detached from the engaging hole 14. There is nothing. Furthermore, since the engaging claw 16 of the protector 15 is located outside the proximal side connecting member 9, even if an external force is applied to the engaging claw 16 in the inner direction, deformation to the inside of the engaging claw 16 is prevented. The protector 15 is not easily detached from the cover 13.
[0051]
When cleaning, the floor suction tool 17 is slid back and forth while grasping the vicinity of the hand side connection member 9. In the state where the hand side connection member 9 is gripped and lifted, the hose member 4 is lowered by its own weight, so the hose member 4 tends to bend at a steep angle from the vicinity of the end of the hand side connection member 9. The protector 15 having a hardness higher than 4 reinforces the hose member 4 to prevent the hose member 4 from being bent at a steep angle and to prevent the hose member 4 from being damaged.
[0052]
In addition, the overlapping portion between the hose member 4 and the main body side connecting member 8 has the same structure as the overlapping portion between the proximal side connecting member 9 and the hose member 4, so that the cleaner main body 1 has a step such as a sill. Even when the hose 3 is pulled in a direction other than the traveling direction of the cleaner body 1 in the hooked state, the hose member 4 is suddenly moved by the protector 15 with the end of the body side connection member 8 as a fulcrum. Bending at an angle is suppressed and the hose member 4 is prevented from being damaged.
[0053]
Since the protector 15 is formed in a bellows shape, durability and strength against bending are improved, the hose member 4 can be protected for a long time, and the protector 15 is not wrinkled at the time of bending. The appearance can be improved. Moreover, since the pitch of the unevenness of the bellows of the protector 15 is made larger than the height of the unevenness, the curving property of the hose member 4 is not greatly impaired even if the protector 15 is attached, and the cleaning workability is reduced. There is no. Furthermore, the height of the irregularities of the bellows of the protector 15 is formed larger than the gap between the inner surface of the protector 15 and the hose member 4, and the inner surface of the protector 15 and the outer surface of the hose member 4 are brought close to each other. It curves with the member 4 and can protect the hose member 4 more reliably.
[0054]
In addition, since the spiral direction of the irregularities of the bellows of the protector 15 intersects with the spiral direction of the irregularities of the bellows of the hose member 4, the irregularities of the bellows of the protector 15 will remain in the bellows of the hose member 4 even if the hose member 4 is curved. And the bendability of the hose member 4 is not impaired.
[0055]
When storing, as shown in FIG. 7, the vacuum cleaner body 1 is in an upright state, the flexible hose 3, the extension pipe 10, and the floor suction tool 17 are connected to the cleaner body 1, and the extension pipe 10 The engaging means (not shown) provided on the engaging portion is engaged with the engaging portion of the cleaner body 1, and the extension pipe 10 is locked to the cleaner body 1.
[0056]
The hose member 4 uses a material having high resilience and elasticity so that it can be restored even if the hose member 4 is accidentally stepped on. In this embodiment, EVA containing LLPE is used, but this material is relatively heat resistant. Therefore, when the vacuum cleaner body 1 is placed near the heater or in a place where it is exposed to direct sunlight when the temperature is high such as in summer, the hose member 4 becomes soft due to the influence of heat. If the hose member 4 returns to its original hardness and maintains its deformed state, the protector 15 is formed of a material having higher heat resistance than the hose member 4. Therefore, even if the temperature is high, the hose member 4 is not bent suddenly by the protector 15, and the air flow path can be prevented from narrowing.
[0057]
In the above-described embodiment, the bellows uneven pitch of the protector 15 is uniformly formed. However, the pitch of the bellows unevenness of the protector 15 is formed so as to become narrower as the distance from the cover 13 increases. You may comprise so that the rigidity of the protector 15 may become weak as it leaves | separates. With this configuration, it is possible to prevent the hose member 4 from being bent suddenly at the end of the protector 15.
[0058]
Further, the height of the irregularities of the bellows of the protector 15 may be formed so as to decrease as the distance from the cover 4 increases, and the rigidity of the protector 15 may decrease as the distance from the cover 4 increases.
[0059]
Further, as shown in FIGS. 8 and 9, the turning direction of the irregularities of the bellows of the protector 15 may be configured to coincide with the turning direction of the bellows of the hose member 4. In this configuration, when the hose member 4 is curved, the irregularities of the bellows of the hose member 4 and the bellows of the protector 15 mesh with each other, the curvature of the hose member 4 is increased, and the durability of the hose member 4 is improved.
[0060]
