Description

【0001】
【発明の属する技術分野】
本発明は、電動送風機の駆動状態に伴って発音手段および発光手段が別個独立して発音および発光する電気掃除機に関する。
【0002】
【従来の技術】
従来、この種の電気掃除機としては、例えば電動送風機およびこの電動送風機の入力を制御する制御手段を収納する電気掃除機本体に発音手段であるブザーや発光手段である発光ダイオードなどを配設し、この電気掃除機本体に接続したホースなどの手許に、電動送風機の駆動状態を設定する操作手段を設けたものが知られている。そして、この操作手段の操作により電動送風機の駆動状態を設定することにより、制御手段にて電動送風機の入力を制御するとともに、発音手段を所定の音や合成音声で発音させたり、発光手段を発光させて掃除作業者に設定状況を報知している。
【0003】
また、一般に電気掃除機本体の制御手段およびホースの手許の操作手段の間は、軽量化、簡素化などのために2線信号線で接続されている。また掃除機本体のごみづまりなどのときに発音手段を発音させたり発光手段を発光させて、掃除作業者に報知するものも知られている。
【0004】
【発明が解決しようとする課題】
しかしながら、上記従来の電気掃除機は、発音手段の音量を一定としているため、異なる設定内容の報知やごみ詰まりなどの異なる情報を2線信号線で発音することが困難であり、また操作手段の設定操作に対応して発音手段で設定内容を発音させる制御を行う高価な記憶手段などを別途設ける必要があり、コストが増大する。さらに、掃除作業者に容易に報知できるようにホースの手許に配設した場合には、手許が大型化するとともに、手許は掃除作業の際に家具などとの衝突や掃除の中断の際に床面に載置させる衝撃などを多く受けるので、手許に設けた記憶手段などが損傷するおそれがある。
【0005】
本発明は、上記問題点に鑑みなされたもので、簡単な構造で電動送風機の駆動状態に応じて発音手段および発光手段をそれぞれ別個に発音および発光できる電気掃除機を提供することを目的とする。
【0006】
【課題を解決するための手段】
請求項1記載の電気掃除機は、電気掃除機本体と、この電気掃除機本体内に配設された電動送風機と、前記電気掃除機本体と接続されるホースに設けられ、前記電動送風機の駆動状態を設定する操作手段と、前記電気掃除機本体内に設けられ、前記操作手段により設定された駆動状態に対応して前記電動送風機の入力を制御する制御手段とを具備し、前記操作手段は、前記制御手段からの一極性の電流のみで動作し設定された駆動状態に従って電流値を可変する電流制御手段と、この電流制御手段の一極性とは逆極性の電流にて発音する発音手段と、この発音手段に対して並列に接続され、前記電流制御手段の一極性とは逆極性の電流にて発光する発光手段とを備え、前記制御手段は、前記操作手段の電流制御手段からの電流値を検知する電流検知手段と、前記操作手段に電源を供給する電源供給手段と、前記電流検知手段にて、前記ホースが前記電気掃除機本体に接続された状態で前記操作手段により前記電動送風機の駆動状態が設定された際の電流値を検知した際に前記電源供給手段からの電流方向を切り換える電流方向切換手段と、この電流方向切換手段から出力される電流方向が前記逆極性であるとき前記電流検知手段による異なる電流値の検知に対応して前記電源供給手段からの電圧値を可変する電圧切換手段とを備え、この電圧切換手段による電圧値の可変によりこの可変された電圧が前記発音手段および前記発光手段へ供給される電路を切り換える電路切換手段を具備したもので、電掃除機本体内に設けられた制御手段の電流検知手段が、ホースが電気掃除機本体に接続された状態での操作手段による電動送風機の駆動状態が設定された場合の所定の電流値を検知した際に、電流方向切換手段にて電源供給手段から操作手段に供給される電源の電流方向を切り換えて、電流方向が操作手段の電流制御手段の順極性であるとき、操作手段による電動送風機の駆動状態の設定状態に対応して可変された電源供給手段からの電源の電流値を電流検知手段で検知し、検知した電流値に対応して電動送風機の入力を制御し、電流方向が電流制御手段の逆極性であるとき、電流検知手段による異なる電流値の検知に対応して電圧切換手段により電源供給手段からの電圧値を可変させ、この可変された電圧値に対応してこの電圧が発音手段および発光手段へ供される電路を電路切換手段にて切り換え、発光手段または発音手段のいずれかを発光または発音させる。
【0007】
請求項2記載の電気掃除機は、請求項1記載の電気掃除機において、電路切換手段は、定電圧手段およびトランジスタを備えたもので、定電圧手段およびトランジスタにより、電圧切換手段からの変換された電圧により発音手段および発光手段への電力が供給される電路が簡単な構成で容易に切り換えられる
請求項記載の電気掃除機は、請求項1または2記載の電気掃除機において、発光手段および発音手段は、操作手段により設定された駆動状態に応じてそれぞれ動作回数が異なるもので、設定された駆動状態に応じて発光手段および発音手段の動作回数がそれぞれ異なることで、操作手段の設定の内容の識別性が向上する。
【0008】
【発明の実施の形態】
以下、本発明の電気掃除機の実施の一形態を図面を参照して説明する。
【0009】
図4において、1は電気掃除機本体で、この電気掃除機本体1には、ホース2の基端が着脱自在に接続され、このホース2の先端には後方に向けて分岐された形状の手許操作部3が設けられている。また、この手許操作部3の先端には、連結および切り離しにより長さが調節される延長管4を介して吸込口体5が取り付けられている。
【0010】
そして、手許操作部3は、図5に示すように、後方に向けて分岐され先端が自由端の部分が握り部11となり、手許操作部3の上面は握り部11から延長管4の方向に向けて停止設定用のボタン12、自動設定用のボタン13、弱/強設定用のボタン14およびパワーブラシ用のボタン15が1列に順次並んで配設されて操作手段17が構成されている。
【0011】
さらに、手許操作部3の上面には、発光手段としての発光素子である発光ダイオードLED1が配設されているとともに、小さい発音量でも掃除作業者が容易で確実に確認できるように、発音手段としてのブザーBZからの発音が発信されるスクリーン状の窓部18が設けられている。なお、ブザーBZは電気掃除機本体1に配設してもよい。
【0012】
次に、図1を参照して、内部構成について説明する。
【0013】
まず、電動送風機21が電気掃除機本体1内に配設されるとともに、パワーブラシ22が吸込口体5内に配設され、これら電動送風機21およびパワーブラシ22は、それぞれ電力制御用のトライアック23,24を介して商用交流電源Eに接続されている。
【0014】
そして、これらトライアック23,24のゲートには、電気掃除機本体1内に内蔵された制御手段25が接続されている。この制御手段25は電源供給手段26、この電源供給手段26から出力される電源の電流方向を切り換える電流方向切換手段27、電源供給手段26からの電源の電圧値を可変する電圧切換手段28、および、電流検知手段29を有している。
【0015】
さらに、制御手段25には操作手段17が接続され、この操作手段17は、停止設定用のボタン12、自動設定用のボタン13、弱/強設定用のボタン14およびパワーブラシ用のボタン15の操作に従い電流を制御する一極性のみで動作する電流制御手段30を備えている。また、操作手段17は、各ボタン12,13,14,15の操作に従って発光ダイオードLED1を発光させる電流制御手段30とは逆極性で動作する発光手段31、および、この発光手段31に並列に接続された発音手段32を備えている。さらに、操作手段17は、発光手段31の回路である電路と発音手段の回路である電路とを切り換える電路切換手段33を備えている。
【0016】
そして、制御手段25の電流検知手段29は、制御手段25の電源供給手段26から供給された電源の電流制御手段30にて制御された電流の電流値を検知する。
【0017】
なお、制御手段25の一部および操作手段17の具体的な回路は図2に示すようになっている。
【0018】
そして、制御手段25は、各種回路に定電圧を供給する電源供給手段26の定電圧源Vccが接続されたマイクロコンピュータ34を有し、このマイクロコンピュータ34の電流方向を切り換える電流方向切換手段27を構成する電流方向切換ポートP1には、トランジスタQ1のエミッタが接続され、このトランジスタQ1のコレクタにはトランジスタQ2のエミッタが接続され、このトランジスタQ2のコレクタはホース2を電気的に接続する端子Aに接続されている。また、電流方向切換ポートP1の出力端子間である電流方向切換ポートP1は抵抗R1および抵抗R2の直列回路を介して接地され、これら抵抗R1および抵抗R2の接続点にはトランジスタQ2のベースが接続されている。さらに、電流方向切換ポートP1の出力端子は、電流可変用の抵抗R3および定電圧V0を設定するツェナダイオードZD1の直列回路を介して接地され、これら抵抗R3およびツェナダイオードZD1の接続点には、トランジスタQ3のエミッタが接続され、トランジスタQ3のコレクタにはトランジスタQ1のコレクタが接続されている。そして、このトランジスタQ3のベースは、抵抗R4を介してマイクロコンピュータ34の電圧切換手段28を構成する電圧切換ポートP3に接続されている。
【0019】
また、トランジスタQ1のベースはトランジスタQ4のコレクタが接続され、このトランジスタQ4のエミッタは接地され、ベースは抵抗R5を介して電圧切換ポートP3に接続されている。
【0020】
さらに、トランジスタQ1のコレクタおよびトランジスタQ3のコレクタは、抵抗R6を介してトランジスタQ5のベースに接続されるとともに、抵抗R7を介してトランジスタQ6のベースが接続され、トランジスタQ5のエミッタは接地され、トランジスタQ5のコレクタはホース2を電気的に接続する端子Bに接続されている。一方、トランジスタQ6のコレクタはトランジスタQ5のコレクタに接続され、トランジスタQ6のエミッタは抵抗R8を介して定電圧源Vccに接続されている。
【0021】
また、トランジスタQ2のコレクタには、トランジスタQ7のエミッタが接続され、このトランジスタQ7のベースは抵抗R9を介して電流方向切換ポートP1に接続され、このトランジスタQ7のコレクタはマイクロコンピュータ34の操作手段17からの電流を読み取る電流検知手段29を構成する電流読取ポートP2に接続されている。さらに、トランジスタQ7のコレクタには、抵抗R10およびコンデンサC1の並列回路が接続され、これら抵抗R10およびコンデンサC1は接地されている。
【0022】
一方、制御手段25は、電気掃除機本体1にホース2を接続した際に電気掃除機本体1の端子Aおよび端子Bにそれぞれ電気的に接続する端子aおよび端子bにそれぞれ接続する2線伝送線51,52を介して、操作手段17に接続されている。そして、端子aおよび端子b間には、抵抗R11およびダイオードD1の直列回路が接続されている。また、この操作手段17は、2線伝送線51,52間に、発光手段31を構成する発光手段である発光素子としての発光ダイオードLED1、トランジスタQ8のコレクタ、エミッタ、抵抗R12、ダイオードD2およびダイオードD3の直列回路を有し、発光ダイオードLED1に対して並列的にブザーBZおよび抵抗R13の並列回路を構成する発音手段32が接続され、この抵抗R13は抵抗R14を介してトランジスタQ8のベースに接続されるとともに、トランジスタQ9のコレクタに接続され、このトランジスタQ9のエミッタは抵抗R12およびダイオードD2の接続点に接続されている。さらに、端子bとダイオードD2およびダイオードD3の接続点との間には、電圧切換手段28を構成する定電圧手段で所定の電圧値Va以上でオンするツェナダイオードZD2および抵抗R15の直列回路が接続されている。そして、トランジスタQ9のベースは、抵抗R16を介してツェナダイオードZD2および抵抗R15の接続点に接続され、トランジスタQ8,Q9、抵抗R12,R14,R15,R16およびツェナダイオードZD2にて電路切換手段33が構成されている。
【0023】
一方、電流制限用の抵抗R11に対して並列に、停止設定用のボタン12により操作される常開のスイッチ57および抵抗R18の直列回路、自動設定用のボタン13により操作される図示しない常開のスイッチおよび抵抗の直列回路、弱/強設定用のボタン14により操作される図示しない常開のスイッチおよび抵抗の直列回路、パワーブラシ用のボタン15により操作される図示しない常開のスイッチおよび抵抗の直列回路が接続されている。なお、各ボタン12,13,14,15に対応する各抵抗の抵抗値は、それぞれ異なる抵抗値に設定されている。
【0024】
次に、上記実施の形態の動作を図2、図3および表1を参照して説明する。
【0025】
まず、マイクロコンピュータ34は電流方向切換ポートP1および電圧切換ポートP3からそれぞれ10msのパルス出力をするもので、マイクロコンピュータ34の電流方向切換ポートP1からLレベル出力し、電圧切換ポートP3からもLレベル出力する。この電流方向切換ポートP1からのLレベル出力および電圧切換ポートP3からのLレベル出力により、トランジスタQ1およびトランジスタQ3のエミッタには電流が供給されず、これらトランジスタQ1およびトランジスタQ3はオフ状態となり、トランジスタQ4のベースにベース電流が供給されないためトランジスタQ4もオフする。また、トランジスタQ1およびトランジスタQ3のいずれもがオフ状態となることにより、トランジスタQ6はオンし、電流方向切換ポートP1がLレベル出力であることによりトランジスタQ7はオンし、図2に示す回路図中の矢印(1)の方向に電流が流れ、ダイオードD1の逆阻止により、ホース2の発光手段31および発音手段32には電流が流れず、ホース2の電流制御手段30に電流が流れて操作手段17の操作待ちの状態となる。
【0026】
ここで、操作手段17のいずれかのボタン13,14,15を操作することにより回路が閉成して電流が流れ、電流検知手段29を構成する電流読取ポートP2にて、パルス的なタイミングで電流の電流値を検知する。
【0027】
そして、電流読取ポートP2で検知する電流値が0の場合は、2線伝送線51,52間が開放されているので、ホース2が外れていると判断する。また、電流がホース接続の閾値を越えたことを電流読取ポートP2に入力すると、ホース2が接続されて抵抗R11に電流が流れて、操作手段17の各ボタン13,14,15が操作されていないと判断する。
【0028】
ここで、操作手段17の各ボタン13,14,15のいずれかが操作されて、対応するスイッチ58,59,60が閉成されると、抵抗R11より抵抗値の小さい各ボタン13,14,15に対応した抵抗を電流が通って電流値が、所定の閾値の電流値となるので、この電流値を電流検知手段29を構成する電流読取ポートP2で検知し、電動送風機21の入力を電流読取ポートP2で検知した電流値に対応して所定の入力に制御する。すなわち、制御手段25によりトライアック23を制御して、電動送風機21を所定の駆動状態で駆動制御する。
【0029】
このとき、制御手段25は操作手段17の各ボタン13,14,15が操作されたと判断し、電流方向を切り換えるために電流方向切換ポートP1から所定時間Hレベル出力する。また、操作したボタン13,14,15の種類により電圧切換ポートP3からはLレベル出力またはHレベル出力、例えばボタン13,14が操作された場合にはLレベル出力、ボタン15が操作された場合にはHレベル出力する。
【0030】
そして、電圧切換ポートP3からLレベル出力された場合には、トランジスタQ3のベースがLレベルとなりトランジスタQ3がオンし、トランジスタQ2がオンする。また、トランジスタQ6のベースがHレベルとなりトランジスタQ6がオフするとともに、トランジスタQ5にベース電流が供給されることによりトランジスタQ5がオンし、操作手段17の電流読み取りの際の電流方向と電流方向が逆転し、図2に示す回路図中の矢印(2)に沿って抵抗R3を介した定電圧源V0の電流が流れ、ダイオードD1の逆阻止により電流制御手段30には電流が流れず、逆極性の発光手段31に電圧V0の電流が流れる。
【0031】
さらに、発光手段31では、電圧切換ポートP3からLレベル出力されているので、図2に示すように、電圧値がVa以下である電圧値V0の電流によりツェナダイオードZD2の逆阻止にてトランジスタQ9がオフするとともにトランジスタQ8がオンし、発音手段32には電流が流れず、図3および表1に示すように、ブザーBZは発音せず、発光ダイオードLED1が発光する。
【0032】
【表1】

Figure 0003738861
【0033】
また、所定のボタン13,14,15のいずれかが操作、例えばボタン15が操作されて、電圧切換ポートP3からHレベル出力された場合には、電流方向切換ポートP1および電圧切換ポートP3からのHレベル出力により、トランジスタQ3がオフしてトランジスタQ1がオンする。また、トランジスタQ4、トランジスタQ7はオフ状態で、トランジスタQ2がオンし、トランジスタQ5はオン状態でトランジスタQ6はオフ状態になり、操作手段17の電流読み取りの際の電流方向が逆転して極性が反対になり、図2に示す回路図中の矢印(3)に沿って抵抗R3を介さない定電圧源Vccの電流が流れ、ダイオードD1により操作手段17の電流制御手段30には電流が流れない。そして、電圧切換ポートP3からHレベル出力されているので、図2に示すように、電圧値がVa以上である電圧値Vccの電流が流れることによりツェナダイオードZD2がオンしてトランジスタQ9がオンするとともにトランジスタQ8がオフして、発光手段31には電流が流れず、図3および表1に示すように、発光ダイオードLED1が発光せず、ブザーBZが耳障りとなることなく確実に掃除作業者に報知できる音量で発音する。
【0034】
そして、電流方向切換ポートP1からHレベルを所定時間、例えば出力した後、再び電流方向切換ポートP1からLレベル出力して、電流読取ポートP2にて操作手段17の待機状態となる。
【0035】
なお、電流方向切換ポートP1からのHレベル出力の時間は、定電流のパルス出力される1サイクルである例えば10m・sの間では非常に時間が短いので、掃除作業者は発光ダイオードLED1の発光およびブザーBZの発音が確認できないため、掃除作業者が最低限「ピッ」という発光を確認または発音を聞き取れる時間長となるように、定電流パルスが10m・sで出力される場合には10サイクル出力、すなわち、1/10秒程度出力させる制御命令を、あらかじめマイクロコンピュータ34に記憶させておく。
【0036】
一方、電動送風機21の負圧側の圧力を感知する図示しないセンサなどにて負圧が上昇したことを感知した場合には、制御手段25はホース2などにごみが閉塞したり、図示しない集塵袋のごみが一杯になるなどの異常が生じたものと判断し、例えばボタン15が操作されて電圧切換ポートP3からHレベル出力された場合と同様に、発音手段32のみが発音する。なお、この場合には、ボタン15が操作された場合に比して長時間発音させたり、大きい発音量で発音させたり、電圧切換ポートP3からHレベル出力およびLレベル出力を交互に行わせて発光手段31の発光と交互に発音させることによる発光ダイオードLED1の発光とブザーBZの発音が同時に行われているように区別化する。
【0037】
また、停止設定用のボタン12が操作されスイッチ57が閉成されると、抵抗R11より抵抗値が小さい抵抗R18に電流が流れ、この電流値を電流検知手段29の電流読取ポートP2で検知し、電動送風機21の入力を停止するとともに、電流方向切換ポートP1から初期状態のLレベル出力する。
【0038】
上記構成によれば、ホース2の手許操作部3に、電動送風機21の駆動状態を設定する操作手段17を構成する各種ボタン12,13,14,15と、発光ダイオードLED1を備えた発光手段31およびこの発光手段31に並列にブザーBZを備えた発音手段32を設け、2線伝送線51,52の簡単な構成でも、操作手段17の電動送風機21の駆動状態の設定操作を認識するとともに、この認識により電流方向切換手段27にて電流方向を適宜切り換えるとともに電圧切換手段28にて電圧値を切り換え、この電圧切換手段28の電圧値の切換により電路切換手段33にて発光手段31および発音手段32への電力の供給経路を切り換えることにより、発光手段31および発音手段32を操作手段17の設定操作に対応して別個独立して発光または発音でき、掃除作業者が設定内容を容易に認識できる。
【0039】
また、2線伝送線51,52で、従来のように手許操作部3に電源供給手段や記憶手段などを配設する必要がなく、簡単な構造で設定内容を報知できるので、ホース2の製造性の向上および製造コストの低減が得られ、ホース2の重量の低減による掃除作業性も向上できる
【0040】
なお、上記図1ないし図5に示す実施の形態において、操作手段17の各ボタン12,13,14,15が操作されたときに、電流を検知して説明したが、電圧を検知する構成など、操作手段17の操作による設定状態を認識する方法はいずれの方法でもよい。
【0041】
また、ブザーBZの代わりにスピーカを用いたり、合成音声を発音する手段を用いても同様の効果が得られる。
【0042】
そして、発光手段31および発音手段32をホース2の手許操作部3に配設して説明したが、電気掃除機本体1に設けてもできる。この場合には、アップライト型などのように、電気掃除機本体1もしくはこの電気掃除機本体1の近傍に操作手段17や握り部11があるものが好ましい。
【0043】
また、操作手段17の操作により、電流方向切換ポートP1から所定時間「ピッ」と一回だけ発光または発音するように説明したが、操作手段17の各ボタン12,13,14,15ごとに異なる回数で発光または発音させることにより、さらに操作手段17の設定操作の内容やごみ詰まりなどの情報の識別性を向上させるようにしてもできる。
【0044】
さらに、発光ダイオードLED1 1つに限らず、複数設けて操作手段17の設定操作の内容やごみ詰まりなどの情報の識別性を向上させるようにしてもでき、発光素子の代わりにランプなどのいずれのものでもできる。
【0045】
【発明の効果】
請求項1記載の電気掃除機によれば、制御手段の電流検知手段が、ホースが電気掃除機本体に接続された状態での操作手段による電動送風機の駆動状態が設定された場合の所定の電流値を検知した際に、電流方向切換手段にて電源供給手段から操作手段に供給される電源の電流方向を切り換えて、電流方向が操作手段の電流制御手段の順極性であるとき、操作手段による電動送風機の駆動状態の設定状態に対応して可変された電源供給手段からの電源の電流値を電流検知手段で検知し、検知した電流値に対応して電動送風機の入力を制御し、電流方向が電流制御手段の逆極性であるとき、電流検知手段による異なる電流値の検知に対応して電圧切換手段により電源供給手段からの電圧値を可変させ、この可変された電圧値に対応してこの電圧が発音手段および発光手段へ供される電路を電路切換手段にて切り換え、発光手段または発音手段のいずれかを発光または発音させるので、簡単な構成で容易に発音手段または発光手段を別個独立して発音または発光できるとともに情報性を向上できる。
【0046】
請求項2記載の電気掃除機によれば、請求項1記載の電気掃除機に加え、電路切換手段は定電圧手段およびトランジスタを備えたため、電圧切換手段からの変換された電圧により発音手段および発光手段への電力が供給される電路が簡単な構成で容易に切り換えできる
【0047】
求項記載の電気掃除機によれば、請求項1または2記載の電気掃除機に加え、設定された駆動状態に応じて発光手段および発音手段の動作回数がそれぞれ異なることで、操作手段の設定の内容の識別性を向上できる。

BACKGROUND OF THE INVENTION
The present invention relates to a vacuum cleaner in which a sounding unit and a light emitting unit separately sound and emit light according to the driving state of an electric blower.
[0002]
[Prior art]
Conventionally, as this type of electric vacuum cleaner, for example, an electric blower and a buzzer as a sounding means, a light emitting diode as a light emitting means, and the like are disposed in a main body of the electric vacuum cleaner that houses a control means for controlling the input of the electric blower. There is known a device such as a hose connected to the main body of the vacuum cleaner provided with an operation means for setting the driving state of the electric blower. Then, by setting the driving state of the electric blower by operating this operation means, the control means controls the input of the electric blower, and the sounding means is made to sound with a predetermined sound or synthesized voice, or the light emitting means emits light. The setting status is reported to the cleaning worker.
[0003]
In general, the control means of the main body of the vacuum cleaner and the operating means of the hose are connected by a two-wire signal line for weight reduction and simplification. In addition, there is also known a method for notifying a cleaning operator by causing a sounding means to emit a sound or a light emitting means to emit light when the main body of the cleaner is clogged.
[0004]
[Problems to be solved by the invention]
However, since the conventional vacuum cleaner keeps the volume of the sounding means constant, it is difficult to sound different information such as notification of different setting contents and clogging of dust with the two-wire signal line, and the operation means In accordance with the setting operation, it is necessary to separately provide an expensive storage unit that performs control for generating the setting content by the sound generation unit, which increases costs. In addition, if the hose is installed in the hand of the hose so that it can be easily notified to the cleaning worker, the hand will be enlarged, and the hand will be floored when it collides with furniture or when cleaning is interrupted. Since many impacts placed on the surface are received, there is a risk that the storage means provided in the hand may be damaged.

[0024]
Next, the operation of the above embodiment will be described with reference to FIGS.
[0025]
First, the microcomputer 34 outputs a pulse of 10 ms from the current direction switching port P 1 and the voltage switching port P 3. The microcomputer 34 outputs an L level from the current direction switching port P 1 of the microcomputer 34, and the voltage switching port P 3. Also outputs L level. The L level output from the L-level output and the voltage switching port P 3 from the current direction switching port P 1, current is not supplied to the emitter of the transistor Q 1 and the transistors Q 3, the transistors Q 1 and transistor Q 3 It is turned off and turns off also the transistor Q 4 for the base current is not supplied to the base of the transistor Q 4. Further, when both the transistor Q 1 and the transistor Q 3 are turned off, the transistor Q 6 is turned on, and when the current direction switching port P 1 is at the L level output, the transistor Q 7 is turned on. current flows in the direction of arrow (1) in the circuit diagram shown in, the reverse blocking diode D 1, no current flows through the light emitting means 31 and the sound generating means 32 of the hose 2, the current control means 30 of the hose 2 An electric current flows and the operation means 17 is put into a standby state.
[0026]
Here, by operating any one of the buttons 13, 14, 15 of the operation means 17, the circuit is closed and a current flows, and the current reading port P 2 constituting the current detection means 29 has a pulse timing. The current value of the current is detected with.
[0027]
Then, if the current value detected by the current reading port P 2 is 0, since between two-wire transmission lines 51 and 52 is open, it is determined that the hose 2 is disconnected. Further, when the current exceeds the hose connection threshold value is input to the current reading port P 2 , the hose 2 is connected and current flows through the resistor R 11, and the buttons 13, 14, 15 of the operation means 17 are operated. Judge that it is not.
[0028]
Here, is either the operation of the buttons 13, 14, 15 of the operating means 17, the corresponding switch 58, 59, 60 are closed, small buttons resistance value than the resistance R 11 13, 14 , 15 and the current value becomes a current value of a predetermined threshold value. Therefore, the current value is detected by the current reading port P 2 constituting the current detection means 29 and input to the electric blower 21. in response to a current value detected by the current reading port P 2 to be controlled to a predetermined input. That is, the control unit 25 controls the triac 23 to drive and control the electric blower 21 in a predetermined driving state.
[0029]
At this time, the control unit 25 determines that the buttons 13, 14, 15 of the operating means 17 is operated, the predetermined time is H level output from the current direction switching port P 1 to switch the current direction. The type by L level output or the H level output from the voltage switching port P 3 of the buttons 13, 14, 15 has been operated, for example, when the button 13 is operated L-level output, the button 15 is operated In this case, H level is output.
[0030]
When the L level is output from the voltage switching port P 3, the base of the transistor Q 3 becomes L level, the transistor Q 3 is turned on, and the transistor Q 2 is turned on. Further, the base of the transistor Q 6 is turned off the transistor Q 6 is turned to the H level, the transistor Q 5 is turned on by the base current is supplied to the transistor Q 5, the current direction in the current reading of the operating means 17 current direction is reversed, the current of the constant voltage source V 0 through a resistor R 3 flows along the arrow (2) in the circuit diagram shown in FIG. 2, the current control means 30 by the reverse blocking diode D 1 is No current flows, and a current of voltage V 0 flows through the light emitting means 31 having the reverse polarity.
[0031]
Further, since the light emitting means 31 outputs the L level from the voltage switching port P 3 , as shown in FIG. 2, the zener diode ZD 2 is reversely blocked by the current of the voltage value V 0 whose voltage value is V a or less. transistor Q 8 is turned on with the transistor Q 9 is turned off by, no current flows through the sound generating means 32, as shown in Figure 3 and Table 1, the buzzer BZ is not sound, light emitting diodes LED 1 emits light .
[0032]
[Table 1]
Figure 0003738861
[0033]
Also, any manipulation of the predetermined button 13, 14 and 15, for example, the button 15 is operated, when it is H level output from the voltage switching port P 3, the current direction switching port P 1 and the voltage switching port P the H-level output from the 3, the transistor Q 1 is turned on the transistor Q 3 is turned off. In addition, the transistors Q 4 and Q 7 are off, the transistor Q 2 is on, the transistor Q 5 is on and the transistor Q 6 is off, and the current direction when the operating means 17 reads the current is reversed. the polarity is opposite, the current of the resistor R 3 not through the constant voltage source V cc flows along the arrow (3) in the circuit diagram shown in FIG. 2, the current control means of the operating means 17 by the diodes D 1 No current flows through 30. Since the voltage switching port P 3 outputs the H level, as shown in FIG. 2, the zener diode ZD 2 is turned on by the flow of the current of the voltage value V cc whose voltage value is equal to or higher than V a , and the transistor When Q 9 is turned on and the transistor Q 8 is turned off, no current flows through the light emitting means 31, and as shown in FIG. 3 and Table 1, the light emitting diode LED 1 does not emit light and the buzzer BZ becomes annoying. It is pronounced at a volume that can be surely notified to the cleaning worker.
[0034]
Then, after outputting the H level from the current direction switching port P 1 for a predetermined time, for example, the L level is output again from the current direction switching port P 1, and the operating means 17 is set in the standby state at the current reading port P 2 .
[0035]
It should be noted that the H level output time from the current direction switching port P 1 is very short, for example, 10 m · s, which is one cycle in which a constant current pulse is output, so that the cleaning operator can use the light emitting diode LED 1. When the constant current pulse is output at 10 m · s so that the cleaning worker can at least confirm the light emission “beep” or hear the sound, since the sound of the buzzer and the sound of the buzzer BZ cannot be confirmed. A control command for outputting 10 cycles, that is, about 1/10 second is stored in the microcomputer 34 in advance.
[0036]
On the other hand, when it is sensed that the negative pressure has increased by a sensor (not shown) that senses the pressure on the negative pressure side of the electric blower 21, the control means 25 causes the hose 2 or the like to block dust or collect dust (not shown). determines that an abnormality such as dust bag is full occurs, for example, as if the button 15 is H-level output from the voltage switching port P 3 is operated, sound generating means 32 only Could. In this case, as compared with the case where the button 15 is operated, the sound is generated for a long time, the sound is generated with a large sound volume, or the H level output and the L level output are alternately performed from the voltage switching port P 3. Thus, the light emission of the light emitting diode LED 1 and the sound of the buzzer BZ by sounding alternately with the light emission of the light emitting means 31 are differentiated so as to be performed simultaneously.
[0037]
When the stop setting button 12 is operated and the switch 57 is closed, a current flows through a resistor R 18 having a resistance value smaller than that of the resistor R 11 , and this current value is used as a current reading port P 2 of the current detecting means 29. in detecting, it stops the input of the electric blower 21, and L-level output in the initial state from the current direction switching port P 1.
[0038]
According to the above-described configuration, the light-emitting means including the various buttons 12, 13, 14, 15 constituting the operation means 17 for setting the driving state of the electric blower 21 and the light-emitting diode LED 1 in the manual operation portion 3 of the hose 2 31 and a sound generating means 32 having a buzzer BZ provided in parallel with the light emitting means 31, and even with a simple configuration of the two-wire transmission lines 51 and 52, the operation means 17 recognizes the setting operation of the driving state of the electric blower 21. Based on this recognition, the current direction switching means 27 appropriately switches the current direction and the voltage switching means 28 switches the voltage value. By switching the voltage value of the voltage switching means 28, the electric circuit switching means 33 causes the light emitting means 31 and the sound generation. By switching the power supply path to the means 32, the light emitting means 31 and the sound generating means 32 can emit light or sound independently according to the setting operation of the operating means 17, and the cleaning operator can easily recognize the setting contents. it can.
[0039]
In addition, the two-wire transmission lines 51 and 52 do not require the power supply means or the storage means in the manual operation section 3 as in the prior art, and the setting contents can be notified with a simple structure. Improvement in manufacturing performance and reduction in manufacturing cost can be obtained, and cleaning workability by reducing the weight of the hose 2 can also be improved .
[0040]
Incidentally, Oite the form status of the embodiment shown in FIG. 1 to FIG. 5, when the buttons 12, 13, 14 and 15 of the operating means 17 is operated, has been described by detecting the current, detects the voltage Any method may be used as a method of recognizing the setting state by the operation of the operation means 17, such as the configuration to be performed.
[0041]
The same effect can be obtained by using a speaker instead of the buzzer BZ or using a means for generating synthesized speech.
[0042]
The light emitting means 31 and the sound generating means 32 have been described in the hand operation section 3 of the hose 2, but may be provided in the electric vacuum cleaner main body 1. In this case, it is preferable that the vacuum cleaner main body 1 or the operation means 17 or the grip portion 11 be in the vicinity of the vacuum cleaner main body 1 such as an upright type.
[0043]
Further, it has been described that by operating the operating means 17, the current direction switching port P 1 emits light or sounds only once for a predetermined time “beep”, but for each button 12, 13, 14, 15 of the operating means 17. It is also possible to improve the discriminability of information such as the contents of the setting operation of the operation means 17 and dust clogging by emitting light or sounding at different times.
[0044]
Furthermore, the number of light emitting diodes LED 1 is not limited to one, and a plurality of light emitting diodes LED 1 can be provided to improve the identification of information such as setting contents of the operation means 17 and clogging of dust. You can do either.
[0045]
