従来の電気掃除機は図5に示すような構成が一般的であった。以下、その構成について説明する。
【0003】
図5に示すように、掃除機本体1は塵埃を吸引するための電動送風機2を内蔵しており、電動送風機2の吸引側すなわち前方には塵埃を集塵するための集塵室3を設けている。掃除機本体1の前部には集塵室3と連通する吸気口4を設け、この吸気口4には、一端側に手元操作部5を有するホース6の他端側を接続し、手元操作部5側には延長管7や、回転ブラシやこれを駆動する電動機(ともに図示せず)などを備えた吸込具8を接続し、吸込具8、延長管7、ホース6、吸気口4、集塵室3で塵埃吸気経路9を形成している。吸込具8は延長管7の一端に接続して使用する方法と、延長管7を外して手元操作部5の先端部に接続して使用する場合がある。
【0004】
一般的には、掃除を行う人が被掃除床面の状態に合わせて手元操作部5に設けられた操作スイッチを選択し、電動送風機2の電力を制御するものであるが、最近では吸込具8の着脱を検知して自動的に電動送風機2の電力を制御するものもある(例えば、特許文献1参照)。

【実施例】
(実施例1)
本発明の第1の実施例について図1および図2を用いて説明する。図1は本発明の一実施例の電気掃除機のブロック図を示している。
【0025】
図1において、40は被掃除面上の塵埃を掻き出す回転ブラシ(図示せず)を駆動する駆動手段である電動機41とこの電動機41に電力を供給する接続端子42を内蔵した吸込具、30は前記吸込具40に接続し電動機41に電力を供給する接続端子32および吸込具40の接続の有無を検知する検知手段31(本実施例ではマイクロスイッチ34を用いて制御手段35を兼用している)を内蔵した延長管(吸込具40と掃除機本体10とを接続する接続部)である。20は前記吸込具40または延長管30に接続し電動機41に電力を供給する接続端子22および前記吸込具40または延長管30の接続の有無を検知する検知手段21(同様にマイクロスイッチ24を用いており、制御手段25も兼用している)を内蔵したホース(吸込具40と掃除機本体10とを接続する接続部)である。13は塵埃を吸引するための電動送風機、12は前記電動機41に電力を供給する接続端子、14は前記電動送風機を駆動する電動送風機駆動手段であり、これら電動送風機13、接続端子12および電動送風機駆動手段14はいずれも掃除機本体10に内蔵している。
【0026】
図2に検知手段の具体的な一実施例を示す。これは吸込具40と延長管30との接続を示す図である。吸込具40の接続部位には、延長管30に設けられた接続端子32と電気的に接続される接続ピン(接続端子)42および検知リブ49が設けられている。また、延長管30内には検知リブ49に対向する位置に可動板33を備えたマイクロスイッチ34を配設している。ここで、可動板33は検知手段31として、またマイクロスイッチ34は制御手段35として動作する。
【0027】
延長管30の他端とホース20の吸込具40との接続部位についても同様に、延長管30には検知リブ39を、ホース20には可動板23を備えたマイクロスイッチ24を配設し、同様に検知手段21および制御手段25として動作する。なおいずれのマイクロスイッチ(24、34)も、吸込具40への配線の片側に直列にNO(ノーマル・オープン)接続されているため、吸込具40や延長管30が接続されていない状態では、マイクロスイッチの接点はOFF状態となり、吸込具40には電力は供給されない。
【0028】
前記構成において以下その作用を説明する。
【0029】
吸込具40を延長管30に挿入すると、検知リブ49がマイクロスイッチ34の可動板33を押すため、前記マイクロスイッチ34の接点はON状態になり、吸込具40が接続されたかどうかを検知すると同時に吸込具40への電力供給が可能な状態となる。同様に、ホース20に吸込具40または延長管30を挿入するとマイクロスイッチ34はON状態になり、吸込具40に電力が供給される。つまり、ホース20に吸込具40を直接または延長管30を介して間接的に接続した場合にのみ、制御手段25や制御手段35が動作して吸込具40に電力が供給され、これ以外の場合には電力は供給されない。なお本実施例ではマイクロスイッチ24、34を検知手段と制御手段を兼用したが、検知手段と制御手段とを分けても良い。
【0030】
(実施例2)
以下、本発明の第2の実施例について図3を用いて説明する。なお、図1および図2と同様の動作を行うものは同一符号を付し、ここでは説明は省略する。
【0031】
図3において、47は永久磁石でありホース20や延長管30との接続部位側の吸込具40内に配置している。また、36は磁気により接点をONするリードスイッチであり、吸込具40への通電を開閉制御する。延長管30の他端とホース20の接続部位についても、同様に、延長管30の他端側には永久磁石(図示せず)を、ホース20にはリードスイッチ(図示せず)を配設している。それぞれホース20内および延長管30内に、検知手段兼制御手段および検知手段兼制御手段として、前記永久磁石36は、永久磁石47に対向する位置に配設されている。
【0032】
前記構成において以下その作用を説明する。
【0033】
吸込具40を延長管30に挿入すると、永久磁石47の磁気に反応してリードスイッチ36の接点はON状態になり、吸込具40が接続されたかどうかを検知すると同時に吸込具40への電力が供給可能な状態となる。同様に、ホース20に吸込具40または延長管30を挿入すると、リードスイッチ(図示せず)はON状態になり吸込具40に電力が供給される。つまり、ホース20に吸込具40を直接または延長管30を介して間接的に接続した場合にのみ、制御手段および検知手段であるリードスイッチ36とホース20内のリードスイッチ(図示せず)が動作して吸込具40に電力が供給され、これ以外の場合には電力は供給されない。
【0034】
なお本実施例では、前記リードスイッチ36やホース20内のリードスイッチ(図示せず)を検知手段兼制御手段として用いたが、検知手段と制御手段とを分けても良い。また、吸込具への配線数を増やし、永久磁石の替わりに電磁石を用いても良い。さらに磁気の替わりに赤外線などの光を用いても良い。
【0035】
(実施例3)
以下本発明の第3の実施例について図4を用いて説明する。なお図1〜図3と同様の動作を行うものは同一符号を付し、ここでは説明は省略する。
【0036】
図4において、48は吸込具40に内蔵した被検知手段(本実施例では固定抵抗器を用いている)であり接続端子42間に並列に接続している。11は前記被検知手段48と一端を接続する検知手段(本実施例では固定抵抗器を用いている)である。本実施例では前記被検知手段48と検知手段11と直流電源に直列接続しているので、検知手段11の出力は直流電圧となる。なおその一端は交流電源の片側と共通にしているので、配線数は同じままである。また15は、前記検知手段11の出力に応じて吸込具40への電力供給を制御する制御手段であり、実施例1に示した電動機駆動手段14の動作を含んでいる。また16は吸込具40への電力供給が行われている場合に点灯する表示手段(報知手段)であり、本実施例では制御手段15と直列接続している。
【0037】
上記構成による動作は以下の通りである。
【0038】
吸込具40を挿入していない状態では検知手段11の出力電圧は0Vであり、制御手段15はこの出力により吸込具40には電源供給を行わない。したがって、表示手段16は消灯したままである。
【0039】
吸込具40を延長管30に挿入すると、被検知手段48と検知手段15との分圧電圧(例えば2.5V)が検知手段11から出力され、制御手段15は吸込具40に電源供給を行う。これにより表示手段16は点灯し、吸込具40への電力供給が正常に行われていることを目視確認できる。
【0040】
ここで吸込具40やその配線端子間12、22、32または42のいずれかが短絡されていると、被検知手段48と検知手段15との分圧電圧は直流電源電圧そのもの(例えば5V)が検知手段11から出力され、何らかの異常が吸込具40かその配線系統に発生していることがわかるため、制御手段15は吸込具40に電源供給を停止する。これにより吸込具40の故障拡大を招くことも掃除機本体10の故障を招くことも無い。この時表示手段16は消灯する。
【0041】
なお、被検知手段48の固定抵抗値を吸込具の種類に応じて設定すれば、吸込具の種類に応じた電力供給モード(例えば、低電圧駆動やON/OFF制御など)を変更することにより、吸込具の特性に合わせた制御を行うことができる。
【0042】
さらに、これらの技術をセントラルクリーナに応用すれば、セントラルクリーナについても同様の効果を得ることができる。
【0043】
【発明の効果】
本発明によれば、吸込具の接続状態を検知し、その出力に応じて、吸込具への電力供給状態を変更することにより、使用性の高い電気掃除機を提供できる。
