そして、コード通路15の接続口13側には、接続片33aを有する第1の給電コネクタ31と、二股に分れた接続片33b,33cが隔壁17の両側に配置された第2の給電コネクタ32とが設けられており、第1,第2の給電コネクタ31,32は、コード通路15内に設けられたコード34a,34bに接続され、電源スイッチ16を経て掃除機本体1内に設けた制御回路及び電源回路(共に図示せず)にそれぞれ接続される。
【0011】
ここで、第1の給電コネクタ31の接続片33aと、第2の給電コネクタ32の接続片33bとの間隔寸法(以下、単に間隔という)をA、第1の給電コネクタ31の接続片33aと、第2の給電コネクタ32の接続片33cとの間隔をBとする。また、以下の説明では、掃除機本体1側を本体側、吸込口体40側を吸込側という。
コード通路15の吸込側の開口部にはこの開口部を閉塞する蓋板18が設けられており、第1の給電コネクタ31の接続片33a、第2の給電コネクタ32の接続片33a,33cに対応して、後述の受電ピンが挿通される挿通孔19a,19b,19cがそれぞれ設けられている。
【0012】
図3は延長管20の一部断面図で、円筒状の主管21の本体側には接続部21aが設けられており、また、軸方向には接続部21aの近傍までコード通路22が設けられている。このコード通路22の吸込側には、握り部10の場合と同一形状、同一寸法の接続片33aを有する第1の給電コネクタ31と、接続片33b,33cを有する第2の給電コネクタ32とが設けられており、第1,第2の給電コネクタ31,32にはそれぞれコード34a,34bの一端が接続されている。

【0015】
次に、本実施の形態の作用を、主として図5、図6の模式図を用いて説明する。
握り管10に延長管20を接続する場合は、延長管20の受電ピン35a,35bの間隔がBなので、その接続部21aを握り管10の接続口13(図1参照)に挿入すると共に、握り管10の蓋板18に設けた間隔Bの挿通孔19a,19cに受電ピン35a,35bを挿通し、第1の給電コネクタ31の接続片33aに給電ピン35aを、第2の給電コネクタ32の接続片33cに受電ピン35bをそれぞれ接続させることにより、握り管10と延長管20を機械的、電気的に確実に接続することができる。複数の延長管20を連結する場合も、上記に準じて接続することができる。
【0016】
また、吸込口体40を延長管20に接続する場合は、図5の状態では、吸込口体40に設けた受電ピン48a,48bの間隔がAなので、その接続部47を延長管20の主管21の吸込側の開口部に挿入すると共に、延長管20の蓋板24に設けた間隔Aの挿通孔25a,25bに受電ピン48a,48bを挿通し、第1の給電コネクタ31の接続片33aに受電ピン48aを、第2の給電コネクタ32の接続片33bに受電ピン48bをそれぞれ接続させることにより、吸込口体40を延長管20に機械的、電気的に確実に接続することができる。
【0017】
吸込口体40の受電ピン48a,48bの間隔がBの場合は、延長管20の蓋板24に設けた間隔Bの挿通孔25a,25cに受電ピン48a,48bを挿通し、第1の給電コネクタ31の接続片33aと、第2の給電コネクタ32の接続片33cとにそれぞれ接続させればよい。
【0018】
次に、握り管10に直接吸込口体40を接続する場合について、図6を用いて説明する。図6では、吸込口体40の受電ピン48a,48bの間隔がAなので、その接続部47を握り管10の接続口13に挿入すると共に、握り管10の蓋板18に設けた間隔Aの挿通孔19a,19bに受電ピン48a,48bを挿通し、第1の給電コネクタ31の接続片33aに給電ピン48aを、第2の給電コネクタ32の接続片33bに受電ピン48bをそれぞれ接続させることにより、握り管10と吸込口体40を機械的、電気的に確実に接続することができる。
【0019】
接続口体40の受電ピン48a,48bの間隔がBの場合は、握り管10の蓋板24に設けた間隔Bの挿通孔25a,25cに受電ピン48a,48bを挿通し、第1給電コネクタ31の接続片33aと、第2の給電コネクタ32の接続片33cにそれぞれ接続させればよい。
【0020】
上記のように構成した本実施の形態によれば、吸込口体40の受電ピン48a,48bの間隔がA又はBのいずれの場合であっても、延長管20又は握り管10に機械的、電気的に確実に接続することができる。
また、例えば、吸込口体40に設けた回転ブラシ42を駆動する電動機43の仕様が、交流100Vの場合は受電ピン48a,48bの間隔をB、仕様が直流24Vの場合は受電ピン48a,48bの間隔をAとするなど、電動機の仕様に応じて吸込口体40の受電ピン48a,48bの間隔を設定することができ、また、これにより電動機43の仕様などを一目で見わけることができる。
【0021】
[実施の形態2]
本実施の形態は、図7に示すように、第1の給電コネクタ31の接続片33aとの間隔がAである第2の給電コネクタ32の接続片33bと、コード34bとの接続部の間に抵抗体36を接続したものである。
これにより、吸込口体40の受電ピン48a,48bの間隔がAの場合とBの場合とにより、電動機43に給電する電圧を変えることができる。
【0022】
本実施の形態においては、受電ピン48a,48bの間隔がAとBの吸込口体10をそれぞれ1個設け、カーペット等の掃除を行う場合は、受電ピン48a,48bの間隔がBの吸込口体40を延長管20に接続し、回転ブラシ42に強力な回転力を与えて塵埃等を吸引させ、家具等の掃除を行う場合は、受電ピン48a,48bの間隔がAの吸込口体40を握り管10に接続し、低い電圧を電動機43に印加して回転ブラシ42を低速回転させるようにしたので、使用場所によって使い分けすることができ、便利である。
【0023】
上記の説明では、第1の給電コネクタ31の接続片33aとの間隔がAである第2の給電コネクタ32の接続片33bに抵抗体36を接続した場合を示したが、間隔がBである第2の給電コネクタ32の接続片33cに抵抗体36を接続してもよい。
また、握り部10の第2の給電コネクタ32の接続片33b又は33cに抵抗体を接続した場合を示したが、延長管20の第2の給電コネクタ32の接続片33b又は33cにも抵抗体36を接続してもよい。
【0024】
【発明の効果】
本発明に係る電気掃除機は、ホースに設けた握り管及び延長管の吸込側に同形状の第1の給電コネクタ、及び2つの接続片を有する第2の給電コネクタを設けると共に、延長管の本体側に第1の給電コネクタと、第2の給電コネクタの何れか一方の接続片とに対応して一対の受電ピンを設け、これら受電ピンを第1,第2の給電コネクタにそれぞれ電気的に接続するようにしたので、延長管の受電ピンの間隔と吸込口体の受電ピンの間隔とが異なる場合でも、吸込口体を握り管又は延長管に確実に接続することができる。
