Description

【０００１】
【発明の属する技術分野】
本発明は、掃除機用吸込み口およびそれを用いた電気掃除機に関するものである。
【０００２】
【従来の技術】
従来この種の吸込み口としては特開平１０−３２８０９８号公報に記載されているものがある。図２１を用いて従来の掃除機用吸込み口の構成を説明する。
【０００３】
図２１において、１は平面が長方形状をした吸込み口本体であり、吸込み口本体１の底面、すなわち、床面２に対面する下面には吸引口３を設けている。４は吸込み口本体１内に回転自在に配した回転ブラシで、吸引口３から床面に臨み、床面上の塵埃を掻き出すものである。６は吸込み口本体１内に形成した吸込み室と連通する連通管で、この連通管６は延長管（図示せず）、ホース（図示せず）を介して電動送風機を収容した電気掃除機本体に接続され、電動送風機の吸引力がホース、延長管、連通管６を介して吸込み室内に作用し、この吸込み室の下方の吸引口３をから回転ブラシ４で掻き上げた塵埃を吸引するようにしている。
【０００４】
吸込み口本体１の操作性を良くするために、連通管６の一端部は吸込み口本体１の後部中央に傾動自在に取り付けられている。つまり、床面に対し平行な第１の回動軸１１を中心に矢印１０ａ方向に回転自在に取り付けられており、また、連通管６の途中は第１の回動軸１１と直交する第２の回転軸１２によって矢印Ａ１０ｂで示すような左右方向に回動自在に取り付けられている。
【０００５】
そして、連通管６を第１及び第２の回動軸１１、１２の２ヶ所で回動することにより、図２１（ｃ）に示すように連通管６を床面２に対し垂直な状態に傾動させた後、連通管６の途中に設けた第２の回動軸１２を中心に左右方向に回動すると、連通管６の他端部に接続する延長管を吸込み口本体１の長手方向に対し平行にすることができ、この状態で延長管を前後方向に移動させると、吸込み口本体１の短手部１ａを前進させることができ、吸込み口本体１の短手部１ａから壁と家具の間の狭い隙間に入り込ませを掃除ができるようにしている。
【０００６】
このように最近の掃除機は吸込み口本体１の操作性を向上させるために、複数の回動軸１１、１２を有して連通管６と吸込み口本体１が接続されている。
【０００７】
【発明が解決しようとする課題】
しかし、上記従来の構成では、吸込み口本体１を自在に回転させるために、塵埃が流れる通路である連通管６に回動軸部を２ヶ所設けているので、この回動部分でも塵埃が流れる広さを確保しなければならないので、例えば、図２１（ｃ）に示すように連通管６を垂直に傾動させた状態で、第２の回動軸１２を中心に回動して床面と平行とした場合には、第２の回動部分が吸込み口本体１の上面より突出し、ベッドの下などを掃除する場合にはその突出した部分がベッドに当たり、ベッド下の奥側を掃除することができないという課題を有していた。
【０００８】
また、吸込み口本体１の移動操作性を向上するために塵埃が流れる連通管６に回動部を設けると、その回動部分では塵埃の流れが大きく変化し、また、これら変化にも対応させて塵埃を目詰まりすることなく流そうとすれば連通管６の内径を大きくとらなければならず、連通管６が大型化し吸込み口自体の大型化につながっていた。
【０００９】
本発明は、上記課題を解決するもので、吸込み口を小型化して吸込み口本体の移動操作性を良好とすることを目的とする。
【００１０】
【課題を解決するための手段】
上記目的を達成するために本発明は、吸込み口本体に回転自在に取り付けた操作棒とやはり吸込み口本体に設置された先端ホースと接続する連通管を備え、吸込み口を操作する操作棒と塵埃を通過させる連通管を別体にし横方向に並べて設置した構成とする事により、省スペースな取り付けが可能になり小型で操作性の良い電気掃除機用の吸込み口を実現できる。
【００１１】
【発明の実施の形態】
本発明の請求項１に記載の発明は、平面形状が左右に長く前後に短い吸込み口本体と、前記吸込み口本体の下面に設けられた吸引口と、前記吸引口と連通し前記吸い込み口本体内に設けた吸込室と連通する連通管と、前記連通管に一端側が連通され、他端側に電動送風機の吸引力が作用する可撓性のホースと、一端に把手が設けられ他端を前記吸込み口本体に回動自在に取り付けた操作棒を備え、前記連通管と前記操作棒とを前記吸込み口本体の長手方向で離して設けた掃除機用吸込み口とすることにより、吸込み口を操作する機能と塵埃を吸引する機能を分離することができ、省スペースな配置が可能になり小型で操作性に優れた吸込み口を実現できる。
【００１２】
本発明の請求項２記載の発明は請求項１記載の掃除機用吸い込み口の操作棒を吸込み口本体に対し傾動自在で、かつ、その傾動する軸と直交する軸心周りに回転可能に取り付けられるようにすることにより、操作棒が自在に回転し操作性が良く狭い場所でも掃除可能な吸込み口を実現できる。
【００１３】
本発明の請求項３記載の発明は、特に、請求項１または２に記載の発明の操作棒の他端を、吸込み口本体の長手方向の略中央でかつ上部もしくは後方に取り付けたことにより、ホースと操作棒の追随性が良くなりさらに操作性が改善される。

【００１７】
本発明の請求項７記載の発明は、特に請求項６記載の発明の第一の操作棒を左右側壁に取り付けることにより、連通管回りの空間が広くなり集塵性が向上する。
【００１８】

【００２０】
【実施例】
以下本発明の実施例について、図面を参照しながら説明する。
【００２１】
（実施例１）
図１に、本発明の第一の実施例における掃除機用吸込み口を電気掃除機で使用した様子を示し、図２に、掃除機用吸込み口の平断面図、側断面図を示す。
【００２２】
図１において、２０は電動送風機を収容した電気掃除機本体を示し、電動送風機の吸引力が作用する吸引部２０ａにホース２２の一端が接続されている。ホース２２の他端は吸込み口２１が接続されている。吸い込み口２１の外郭を構成する吸込み口本体２４の後方には操作棒３０の一端を回転自在に取り付けられている。操作棒３０の他端には把手３０ｃが固定されている。２５は床面を示す。
【００２３】
図２において、吸込み口本体２４は、左右方向に長く前後方向に短い略箱状をしており、具体的には、床面２５にほぼ垂直で左右方向の２枚の長側壁２６と、床面２５にほぼ垂直で前後方向の２枚の短側壁２７と、長側壁２６と短側壁２７とで囲まれる上面を覆う上面壁２８等の外壁によって構成され、下面は床面２５に対して開口し吸引口２９を構成している。これら外壁は曲面で構成し、それぞれの境界が不明確であってもよい。吸込み口本体２４の平面形状は左右方向が前後方向より長く、例えば略長方形状または楕円形状であっても良い。
【００２４】
吸込み口本体２４の上面壁２８のほぼ中央から後方にかけて形成された凹部Ａ３１は後方を開放しており、この凹部Ａ３１の前壁（長側壁３２と平行）を操作棒取り付け壁３２とし、この操作棒取り付け壁３２に接続部３５の一部が回動自在に取り付けられている。接続部３５の他端部には操作棒３０の一端部を回動自在に取り付け、操作棒３０が吸込み口本体２４に対し傾動自在で、かつ左右方向に回転自在としている。
【００２５】
図３に示すように、接続部３５は、軸部３５ａと、軸孔３５ｂを有した２つの側壁３５ｃと後壁３５ｇからなるコの字型の軸支持部３５ｄから構成されており、軸部３５ａの一端は後壁３５ｇの背面のほぼ中央に固定されている。軸部３５ａの他端は操作棒取り付け壁３２に取り付けられた軸受け３４に挿入され、他端には挿入した後の抜けを防止するために止め板３５ｅを固定している。接続部３５の軸部３５ａを操作棒取り付け壁３２に垂直、言い換えれば長側壁２６にほぼ垂直となるように回転軸３３回りに回転自在に取り付ける。円柱状の操作棒３０の一端は板状に加工され、この板状部３０ａには軸孔３０ｂが設けてある。この板状部３０ａをコの字型の軸支持部３５ｄの２つの側壁３５ｃで挟持し、軸孔３０ｂとその両側に対向する軸孔３５ｂを貫通するように軸３８を挿入し、軸３８を軸孔３５ｂに固定することにより、操作棒３０を操作棒回転軸３７回りに回転可能に取り付けられる。
【００２６】
図２、図４において、３９は吸込み口本体２４内部とホース２２を接続する連通管を示している。連通管３９は長側壁２６にほぼ平行な第一の連通管３９ａと第一の連通管３９ａとほぼ直角に取り付けられた第２の連通管３９ｂから構成され、図４に示すように、第２の連通管３９ｂの一端が第１の連通管３９ａのほぼ中央に連通接続されたＴ字型の形状を有している。第一の連通管の両端４２ａ、４２ｂ及び第２の連通管３９ｂの一端４３に開口孔４４ａ、４４ｂ、４４ｃを有し、第２の連通管３９ｂの他端４３には柔軟なホース２２が接続されている。第一の連通管３９ａの開口孔４４ａ、４４ｂは、吸い込み口本体２４内すなわち吸込室２４ａと連通している。吸込み口本体２４の上面壁２８には凹部Ａ３１と間隔をおいて、すなわち右方向にずらした位置に後方に延びる凹部４０が設けられ、この凹部４０の後方も開放している。そして凹部４０の短側壁２７にほぼ平行な側壁部４０ａ、４０ｂには連通孔４１ａ、４１ｂを設けている。凹部４０の両側壁部４０ａ、４０ｂの連通孔４１ａ、４１ｂに第一の連通管３９ａの両端４２ａ、４２ｂが回転自在に嵌合し取り付けられている。４５は連通管の回転軸を示しており、連通管３９はこの連通管回転軸４５を中心に上下方向に回転可能である。吸引口２９から吸い込まれた塵埃は空気とともに連通管３９の開口孔４４ａ、４４ｂを通過し、連通管３９内部を通り、ホース２２へと運ばれる。
【００２７】
図１において、５０はホース２２と操作棒３０を連結支持する連結材を示す。本実施例では操作棒３０の軸方向に間隔をあけた２ヶ所に連結材５０が設置されている。図２に連結材５０が使用されている部分の断面を示す。本実施例では連結材５０は、操作棒３０より径大のリング状をしており、連結材５０の一部を操作棒３０に固定し、連結材５０と操作棒３０との間に形成される空間にホース２２を通すようにしている。しかも、連結材５０の内周部とホース２２の外周部には隙間５１が設けられ、ホース２２は摺動可能になっている。図５に各種の形状をした連結材の例を示す。図５（ａ）（ｂ）は連結材５０ａの使用部分の正面断面図と平面断面図を示す。操作棒３０にはリング状の連結材５０ａの一部がピン５２ａで固定され、ホース２２は、連結材５０ａと操作棒３０との間の空間内に貫通され、ホース２２の外周と連結材５０ａの内周との間に隙間５１を設けて、摺動可能になっている。図５（ｃ）（ｄ）の例では連結材５０ｂが操作棒側連結材５０ｃとホース側連結材５０ｄの２部品から構成され、両者はピン５２ｂで固定している。操作棒３０の外周を覆うリング状の操作棒側連結材５０ｃはピン５２ａで操作棒３０に固定されている。ホース２２はリング状のホース側連結材５０ｄに貫通し、ホース側連結材５０ｄの内周部とホース２２の外周部に隙間５１を設け、ホース２２は摺動可能になっている。図５（ｅ）（ｆ）の例では操作棒側連結材５０ｃと操作棒３０の間にも隙間５１を設け摺動可能にしている。ただし、操作棒３０には操作棒側連結材と当接する鍔５４があり、操作棒側連結材５０ｃが操作棒３０の軸方向へ動くのを規制している。連結材５０と操作棒３０、ホース２２との動きの自由度を増せば操作棒３０の動きに対しホース２２がより抵抗無く動けるようになり、操作性が向上する。又連結材が柔軟な弾性体から構成されていても良い。
【００２８】
以上のように構成された吸込み口２１の動作について説明する。掃除機本体２０内の電動送風機を駆動し吸引力が生じると、床面２５上の塵埃（図示せず）は吸込み口本体２４の吸引口２９から吸引され連通管３９、ホース２２を通過し掃除機本体２０内に集塵される。吸込み口本体２４の操作に関しては、把手３０ｃを持ち操作棒３０を動かす。
【００２９】
次に吸込み口本体２４の操作性について説明する。図６は吸込み口で幅の狭い場所を掃除するために、操作棒３０を床面２５に対しほぼ直角に立て、その後回転軸３３を中心に横に倒した様子を示し、図６（ａ）は上面からみた図を示し、図６（ｂ）は後面からみた図を示す。操作棒３０を床面２５に対して直角近くに立てると連結材５０で繋がったホース２２も追随し、連通管回転軸４５の回りに回転し床面２５に対してほぼ直角に立つ。連結材５０が無く操作棒３０とホース２２が繋がっていない場合でも、操作棒３０操作時に手でホース２２を持てば簡単にホース２２を立てることができる。このようにすれば、操作棒３０の接続部３５、連通管３９が吸い込み口本体２４の幅方向からはみ出る事が無く、吸い込み口本体２４の長手方向に操作棒３０を押せば吸い込み口本体２４も長手方向に簡単に動かすことができ、家具間の狭い隙間にも吸い込み口が入り、掃除が可能になる。図７は操作棒３０を立てた後操作棒３０を回転軸３３回りに回転させた場合のホース２２の追随性を示す図であり、連結材５０で操作棒３０と連結されたホース２２は図７（ａ）で示すように回転させた場合連結材５０とホース２２で摺動し、連結材５０と連通管３９間のホース２２が図７（ｂ）の中立位置に比べ長くなりホース２２は操作棒３０に追随する。図７（ｃ）は反対に連結材５０と連通管３９間のホース２２が短くなりホースは操作棒３０に追随する。ホース２２が十分に柔軟であれば、連通管３９が回転可動でなくても操作棒３０の自在な動きに抵抗無く追従することは可能であり、横幅を小さくして掃除が可能である。しかし連通管３９部分が吸い込み口本体２４の幅方向（前後方向）からはみ出し、吸い込み口本体２４とこれに接続する連通管３９を含めた吸い込み口２１の全幅（前後方向の長さ）は大きくなる。
【００３０】
以上のように操作棒３０、ホース２２を床面２５に対して立てると、吸い込み口２１の全体の幅方向の寸法を小さくできる。連通管３９を回動させれば吸込み口本体２４の短側壁２７の長さすなわち吸込み口本体２４の幅内にホース２２，操作棒３０を収める事もでき、幅方向の狭い場所でも操作棒３０、ホース２２が邪魔にならず簡単に掃除ができる。一般に幅方向の小さな場所は家具と家具の隙間など、上方向の空間は空いているため、立てた操作棒３０、ホース２２が吸込み口本体２４の操作に対し障害になることは少ない。図２（ｃ）は操作棒３０を操作棒回転軸３３の回りに回転させ、連通管３９、ホース２２が連通管回転軸４５の回りに追随して回転し、操作棒３０、ホース２２が水平になった状態を示している。図２（ｂ）は操作棒３０，ホース２２を上方向に回転させた様子を示している。図２（ｃ）のように操作棒３０を回転させ吸込み口本体２４の高さ内にホース２２、操作棒３０が収まると、高さ方向の小さな隙間などでも掃除が可能になる。高さ方向の小さな隙間は一般にベッド、ピアノ等の下の空間で横方向の空間は空いている場合が多く、水平にした操作棒３０延長管２３、ホース２２が吸込み口本体２４の操作に対し障害になることは少ない。
【００３１】
以上のように吸込み口本体２４に操作力を伝える操作棒３０と、塵埃が通過するホース２２と接続する連通管３９を別体で横並び、すなわち吸い込み口本体２４の長手方向離して、に取り付けることにより吸込み口全体の幅と高さを小さくすることができる。又、操作棒３０を吸込み口本体２４に可動に取り付け、先端ホース２２を柔軟にかつ吸込み口本体２４への接続部分に可動性を持たせることにより、高さ方向、及び幅方向の小さな場所の掃除が可能になる。操作棒３０、ホース２２の吸込み口本体２４への取り付け可動性を制限しても、操作棒３０と先端ホース２２を横並びに併置する事により従来の吸込み口本体に比べ全高、全幅寸法を小さくできる。ホース２２の柔軟性を良くすれば連通管３９の上下方向の回動性を無くしても従来の吸込み口本体に比べればより狭い場所の掃除が可能になる。又、ホース２２と第２の連通管３９ｂの接続部分にホース２２の軸に対して回転自在性を持たせればなお操作性は向上する。
【００３２】
（実施例２）
図８は、本発明の第２の実施例の吸い込み床ノズルの平面断面図、及びその側断面図である。実施例１と同様の部分は同一番号を付してその説明を省略する。
【００３３】
本実施例では、連通管３９は構成は実施例１の場合と同様であるが吸い込み口本体２４への取り付く場所が異なり、本実施例では吸い込み口本体２４の長手方向ほぼ中央に設置され、連通管３９は吸い込み口本体２４に対し、傾動自在に取り付けている。接続部３５は操作棒取り付け壁３２に固定されており、回動しない。接続部３５には第一の操作棒６１が操作棒回転軸３７の回りに回動可能（傾動自在）に取り付けられている。
【００３４】
６２は連結支持部を示し、図９では連結支持部６２付近の分解図を示している。図９（ａ）は連結支持部６２の側面組立図、（ｂ）は平面組立図、（ｃ）は正面図である。連結支持部６２の吸い込み口側側壁に操作棒取り付け孔６２ａ、連通管取り付け孔６２ｂを有し、それぞれ第一の操作棒６１、連通管３９の第二の連通管３９ｂを挿入し、圧入固着されており、第一の操作棒６１と連通管３９を剛体結合している。第二の連通管３９ｂは連通管取り付け孔６２ｂを貫通し、その一端にはホース２２が接続されている。連結支持部６２のほぼ中央には、吸い込み口と反対側に弧を形成する平面形状が半円形の第二操作棒接続部６３が構成されている。第二操作棒接続部６３は対向した二つの側壁６２ｃ、６２ｄとその間に構成された溝６４を有し、コの字形状に構成されている。側壁６２ｃ、６２ｄにはそれぞれ軸孔６２ｅ、６２ｆが設けられこれら軸孔６２ｅ、６２ｆの軸孔中心軸６５は同一であり、その方向は、第一の操作棒の中心軸６１ａ及び操作棒回転軸３７それぞれとほぼ直交する。第二の操作棒６６の一端には把手（図示せず）が固着され、他端は、操作棒軸孔６６ｂを有した平面部６６ｃを有している。この平面部６６ｃは溝６４に挿入され、重なった軸孔６２ｅ、操作棒軸孔６６ｂ、軸孔６２ｆを回転軸６８が貫通し、回転軸６８は軸孔６２ｆに圧入固定され、第二の操作棒６６は軸孔中心軸６５の回りに回転可能に取り付けられる。すなわち、第二の操作棒６６を床面２５とほほ水平に回動できる、言い換えれば床面２５とほぼ垂直にすることのできる軸孔中心軸６５を有している。７０は吸込み口本体２４内に設置された回転ブラシを示し、両端が軸受け７１、７２で吸込み口本体２４に支持されている。回転ブラシ７０の外周には植毛７３がされており、一端にはブラシ用プーリ７４が固着されている。７５は駆動用モータを示し、防振ゴム７６、７７を介して吸込み口本体２４内に固定されている。駆動用モータ７５の回転軸７８の先端にはモータプーリ７９が固着され、ブラシ用プーリ７４との間をベルト８０で連結している。
【００３５】
図１０は第一の操作棒６１、連通管３９を床面２５に対し垂直に立てた場合であり、操作棒６１、ホース２２などが吸い込み口本体２４の幅方向（前後方向）にはみ出す事はなく、狭い隙間でもそうじができる点は実施例１で述べた内容と同一である。本例では連通管３９と第一の操作棒６１が剛に結合されているため、両者は上下方向に同時に回転できるためその操作が確実で操作性がよくなる。図８は第一及び第二の操作棒６１，６６が水平になった状態を示し、上下方向に小さな隙間の空間での掃除が可能になる点は実施例１で述べたことと同一である。
【００３６】
図１１は第一の操作棒６１を立てた状態で、第二の操作棒６６を回動させた例であり、ホース２２と第二の操作棒を連結材５０で連結しておけばホース２２の第二の操作棒６６に対する追随性がよくなり操作性が向上する。
【００３７】
以上述べたように操作棒６１，６６を立てた場合は幅方向にコンパクトに、操作棒６１，６６を水平にした場合は高さ方向にコンパクトになり狭い空間の掃除が可能になる点が本発明の主旨であり、そのため図１２で示すように多少操作棒６１，６６が床面２５と水平で無かったり、軸孔中心軸６５が床面に対し多少垂直でなくてもその本来の効果は変わらない。図１２は第２の操作棒６６が軸孔中心軸６５回りに回転自在に第一の操作棒６１に支持された例であり、図１２（ｄ）は操作棒６１，６６が床面に対し水平な時、軸孔中心軸６５が床面２５に垂直である例を示す。
【００３８】
（実施例３）
図１３は、本発明の第３の実施例の吸い込み口の平面断面図、及びその側断面図である。実施例１、実施例２と同様の部分は同一番号を付してその説明を省略する。
【００３９】
本実施例では第一の操作棒９０は、略Ｓ字状をなし、その一端は、吸い込み口本体２４の短側壁２７に、つまり短側壁２７とほぼ垂直な操作棒回転軸３７回りに回転可能に取り付けられている。他端は、第二操作棒接続部６３に接続されている。連通管回転軸４５と操作棒回転軸３７は同一軸である。第二の連通管３９ｂと第一の操作棒９０は連結支持部６２で連結される。連結支持部６２は剛体で、両者は剛結合されている。
【００４０】
図１４は第一の操作棒９０、第二の操作棒６６を床面２５に対して垂直に立てた場合であり、吸い込み口本体２４の幅方向（前後方向）がコンパクトにできる点は先述した実施例での内容と同様である。５０は連結材を示す。図１３（ｂ）は第一の操作棒９０、第二の操作棒６６を水平にした場合であり、吸い込み口本体２４の高さ方向がコンパクトにできる点は先述した実施例での内容と同様である。図１５は第一の操作棒９０、第二の操作棒６６を立てた状態で第二の操作棒を軸孔中心軸６５の周りに回動させた場合であり、柔軟なホース２２が第二の操作棒６６の動きに抵抗無く追随することがわかる。
【００４１】
以上の様な構成では、第一の操作棒９０が短側壁２７に取り付けられているため、実施例２の構成に比べ、吸込み口本体２４内で第一の連通管３９ａの開口孔４４ａ、４４ｂ周りの空間が広くなり、塵埃が吸気される際の気流の抵抗が小さくなり効率の良い集塵が可能になる。もちろんこの効果は操作棒９０と連結管３９が連結支持部６２が剛結合されず伸縮可能な材料で結合されていても良く、さらに結合されていない場合でも同様に生じる。
【００４２】
図１６、図１７は第一の操作棒９０が傾動する軸６５と、吸い込み口本体２４内に回転自在に配した回転ブラシ７０の回転軸９３とを同一にした他の実施例であり、第一の操作棒９０は吸込み口本体２４を貫通し、両側の短側壁２７で軸受け９５，９６によって支持されている。回転ブラシ７０は内側に設置されたブラシ軸受け９７，９８で第一の操作棒９０に支持される。第一の操作棒９０の剛性を十分大きくしておけば吸込み口本体２４自身の剛性はあまり必要なく、特に軸受け９５，９６の構成は非常に簡素化される。場合によっては柔軟なエラストマ等の弾性材でその殆どを構成することもでき家具などを傷つけない軽量な吸込み口が実現できる。図１８は第一の操作棒９０を床面２５に対し略垂直に立てた場合を示す。又図１９は第一の操作棒９０を立てた状態で第２の操作棒６６を横向けに倒した例であり、ホース２２が第２の操作棒６６に追随する様子が解る。
【００４３】
なお実施例１〜３共に、連通管３９の構成は図２０で示すようにその開口孔１００が長側壁２６に対し開口している形状でも良い。
【００４４】
【発明の効果】
以上のように、本発明によれば、吸い込み口を操作する機能と塵埃を吸引する機能を分離したので、小型で操作性に優れた吸い込み口を提供できる。

Reference numeral 4 denotes a rotating brush that is rotatably disposed in the suction port body 1 and faces the floor surface from the suction port 3 and scrapes dust on the floor surface. 6 is a communication pipe that communicates with the suction chamber formed in the suction port body 1, and this communication pipe 6 is an electric vacuum cleaner body that houses an electric blower via an extension pipe (not shown) and a hose (not shown). The suction force of the electric blower acts on the suction chamber via the hose, the extension pipe, and the communication pipe 6 so that the dust scraped up by the rotary brush 4 from the suction port 3 below the suction chamber is sucked. I have to.
[0004]
In order to improve the operability of the suction port body 1, one end portion of the communication pipe 6 is attached to the rear center of the suction port body 1 so as to be tiltable. That is, it is attached so as to be rotatable in the direction of the arrow 10a about the first rotation shaft 11 parallel to the floor surface, and the second half of the communication pipe 6 is orthogonal to the first rotation shaft 11. The rotary shaft 12 is attached so as to be rotatable in the left-right direction as indicated by an arrow A10b.
[0005]
Then, by rotating the communication pipe 6 at two locations of the first and second rotary shafts 11 and 12, the communication pipe 6 is brought into a state perpendicular to the floor surface 2 as shown in FIG. After tilting, the extension pipe connected to the other end of the communication pipe 6 is moved in the longitudinal direction of the suction port main body 1 when it is turned in the left-right direction around the second rotation shaft 12 provided in the middle of the communication pipe 6. If the extension pipe is moved in the front-rear direction in this state, the short part 1a of the suction inlet body 1 can be advanced, and the short part 1a of the suction inlet body 1 can be moved to the wall.

In this embodiment, the connecting member 50 has a ring shape larger in diameter than the operating rod 30, and a part of the connecting member 50 is fixed to the operating rod 30 and is formed between the connecting member 50 and the operating rod 30. The hose 22 is passed through the space. And the clearance gap 51 is provided in the inner peripheral part of the connection material 50, and the outer peripheral part of the hose 22, and the hose 22 is slidable. FIG. 5 shows examples of connecting members having various shapes. 5 (a) and 5 (b) show a front sectional view and a plan sectional view of a portion where the connecting member 50a is used. A part of the ring-shaped connecting member 50a is fixed to the operating rod 30 with a pin 52a, and the hose 22 is penetrated into the space between the connecting member 50a and the operating rod 30, and the outer periphery of the hose 22 and the connecting member 50a. A gap 51 is provided between the inner periphery and the inner periphery of the inner periphery of the inner periphery of the inner periphery of the inner periphery of the inner periphery of the inner periphery of the inner periphery of the inner periphery. In the example of FIGS. 5C and 5D, the connecting member 50b is composed of two parts, that is, the operating rod side connecting member 50c and the hose side connecting member 50d, and both are fixed by pins 52b.

In the example of FIGS. 5E and 5F, a gap 51 is also provided between the operating rod side connecting member 50c and the operating rod 30 so as to be slidable. However, the operating rod 30 has a flange 54 that comes into contact with the operating rod side connecting member, and restricts the operating rod side connecting member 50c from moving in the axial direction of the operating rod 30. If the degree of freedom of movement between the connecting member 50, the operating rod 30, and the hose 22 is increased, the hose 22 can move without resistance to the movement of the operating rod 30, and the operability is improved. Further, the connecting material may be composed of a flexible elastic body.
[0028]
Operation | movement of the suction inlet 21 comprised as mentioned above is demonstrated. When a suction force is generated by driving the electric blower in the cleaner body 20, dust (not shown) on the floor surface 25 is sucked from the suction port 29 of the suction port body 24 and passes through the communication pipe 39 and the hose 22 for cleaning. Dust is collected in the machine body 20. Regarding the operation of the suction inlet body 24, the handle 30c is held and the operation rod 30 is moved.
[0029]
Next, the operability of the suction port body 24 will be described. FIG. 6 shows a state in which the operating rod 30 is set up at a substantially right angle with respect to the floor surface 25 and then tilted sideways around the rotary shaft 33 in order to clean a narrow place at the suction port. Shows a view from the top, and FIG. 6B shows a view from the back. When the operating rod 30 stands up to a right angle with respect to the floor surface 25, the hose 22 connected by the connecting member 50 also follows, rotates around the communication pipe rotating shaft 45, and stands substantially at a right angle with respect to the floor surface 25. Even when the operating rod 30 and the hose 22 are not connected without the connecting member 50, the hose 22 can be easily erected by holding the hose 22 by hand when operating the operating rod 30. In this way, the connection portion 35 and the communication pipe 39 of the operation rod 30 do not protrude from the width direction of the suction port body 24, and if the operation rod 30 is pushed in the longitudinal direction of the suction port body 24, the suction port body 24 is also It can be moved easily in the longitudinal direction, and a suction port enters a narrow gap between furniture, allowing cleaning. FIG. 7 is a view showing the followability of the hose 22 when the operating rod 30 is rotated around the rotation shaft 33 after the operating rod 30 is erected. The hose 22 connected to the operating rod 30 by the connecting member 50 is shown in FIG. When rotating as shown in FIG. 7A, the connecting member 50 and the hose 22 slide, and the hose 22 between the connecting member 50 and the communication pipe 39 becomes longer than the neutral position in FIG. Follow the operating rod 30. 7C, on the contrary, the hose 22 between the connecting member 50 and the communication pipe 39 is shortened, and the hose follows the operation rod 30. If the hose 22 is sufficiently flexible, even if the communication pipe 39 is not rotatable, it is possible to follow the free movement of the operation rod 30 without resistance, and the lateral width can be reduced for cleaning. However, the communication pipe 39 portion protrudes from the width direction (front-rear direction) of the suction port body 24, and the entire width (length in the front-rear direction) of the suction port 21 including the suction port body 24 and the communication pipe 39 connected thereto increases. .
[0030]
When the operating rod 30 and the hose 22 are raised with respect to the floor 25 as described above, the overall width direction dimension of the suction port 21 can be reduced. If the communication pipe 39 is rotated, the hose 22 and the operation rod 30 can be accommodated within the length of the short side wall 27 of the suction port body 24, that is, the width of the suction port body 24. The hose 22 does not get in the way and can be cleaned easily. In general, a small space in the width direction has a space in the upper direction such as a space between furniture, so that the standing operation rod 30 and the hose 22 are less likely to become an obstacle to the operation of the suction port body 24. 2C, the operating rod 30 is rotated around the operating rod rotating shaft 33, the communication pipe 39 and the hose 22 follow and rotate around the communicating pipe rotating shaft 45, and the operating rod 30 and the hose 22 are horizontal. This shows the state. FIG. 2B shows a state where the operating rod 30 and the hose 22 are rotated upward. When the operating rod 30 is rotated and the hose 22 and the operating rod 30 are accommodated within the height of the suction port body 24 as shown in FIG. 2C, cleaning can be performed even in a small gap in the height direction. The small gap in the height direction is generally a space below the bed, piano, etc., and the horizontal space is often vacant. The horizontal operation rod 30 extension pipe 23 and hose 22 are used for the operation of the suction inlet body 24. There are few obstacles.
[0031]
As described above, the operating rod 30 for transmitting the operating force to the suction port body 24 and the communication pipe 39 connected to the hose 22 through which dust passes are arranged side by side separately, that is, separated from the longitudinal direction of the suction port body 24. Thus, the width and height of the entire suction port can be reduced. Further, the operation rod 30 is movably attached to the suction port main body 24, and the tip hose 22 is flexible and has mobility at the connecting portion to the suction port main body 24, so that a small place in the height direction and the width direction can be obtained. Cleaning is possible. Even if the operation mobility of the operation rod 30 and the hose 22 to the suction port main body 24 is limited, the overall height and width can be reduced by arranging the operation rod 30 and the tip hose 22 side by side as compared with the conventional suction port main body. . If the flexibility of the hose 22 is improved, it is possible to clean a narrower place as compared with the conventional suction port body even if the vertical rotation of the communication pipe 39 is lost. Further, if the connecting portion between the hose 22 and the second communication pipe 39b is made rotatable with respect to the axis of the hose 22, the operability is further improved.

FIG. 13 is a plan sectional view and a side sectional view of a suction port according to a third embodiment of the present invention. The same parts as those in the first and second embodiments are denoted by the same reference numerals, and the description thereof is omitted.
[0039]
In the present embodiment, the first operating rod 90 is substantially S-shaped, and one end thereof can rotate around the short side wall 27 of the suction inlet body 24, that is, around the operating rod rotating shaft 37 substantially perpendicular to the short side wall 27. Is attached. The other end is connected to the second operation rod connecting portion 63. The communication tube rotating shaft 45 and the operating rod rotating shaft 37 are the same axis. The second communication pipe 39 b and the first operation rod 90 are connected by a connection support portion 62. The connection support part 62 is a rigid body, and both are rigidly connected.
[0040]
FIG. 14 shows a case where the first operation rod 90 and the second operation rod 66 are set up vertically with respect to the floor surface 25, and the point that the width direction (front-rear direction) of the suction port body 24 can be made compact is described above. This is the same as in the embodiment. Reference numeral 50 denotes a connecting material. FIG. 13B shows a case where the first operating rod 90 and the second operating rod 66 are horizontal, and the point that the height direction of the suction port body 24 can be made compact is the same as in the above-described embodiment. It is. FIG. 15 shows a case where the second operating rod is rotated around the shaft hole central axis 65 in a state where the first operating rod 90 and the second operating rod 66 are raised, and the flexible hose 22 is connected to the second operating rod 66. It can be seen that the movement of the operation bar 66 follows without resistance.
[0041]
In the configuration as described above, since the first operating rod 90 is attached to the short side wall 27, compared with the configuration of the second embodiment, the opening holes 44a and 44b of the first communication pipe 39a in the suction port body 24. The surrounding space is widened, the resistance of the airflow when dust is sucked in is reduced, and efficient dust collection is possible. Of course, this effect may occur when the operating rod 90 and the connecting tube 39 are connected by a stretchable material without the connecting support 62 being rigidly connected, and even when they are not connected.
[0042]
FIGS. 16 and 17 show another embodiment in which the shaft 65 on which the first operating rod 90 tilts and the rotation shaft 93 of the rotary brush 70 rotatably arranged in the suction port body 24 are the same. One operating rod 90 penetrates the suction inlet body 24 and is supported by bearings 95 and 96 on the short side walls 27 on both sides. The rotating brush 70 is supported on the first operating rod 90 by brush bearings 97 and 98 installed inside. If the rigidity of the first operating rod 90 is sufficiently large, the rigidity of the suction port body 24 itself is not necessary, and the configuration of the bearings 95 and 96 is particularly simplified. In some cases, most of the material can be made of an elastic material such as a flexible elastomer, and a lightweight suction port that does not damage furniture or the like can be realized. FIG. 18 shows a case where the first operating rod 90 is set substantially perpendicular to the floor surface 25. FIG. 19 shows an example in which the second operation rod 66 is tilted sideways while the first operation rod 90 is upright, and it can be seen that the hose 22 follows the second operation rod 66.
[0043]
In each of the first to third embodiments, the communication pipe 39 may have a configuration in which the opening hole 100 is open to the long side wall 26 as shown in FIG.
[0044]
【The invention's effect】
As described above, according to the present invention, since the function of operating the suction port and the function of sucking dust are separated, a suction port having a small size and excellent operability can be provided.
