Description

【００３８】
表１で示すように、メインスイッチでは冷風、温風、熱風の基本運転モードを選択可能とし、その選択した基本運転モードにおいて、熱風のモード以外では、サブスイッチによりファン出力を制御して、風量の増減（強弱）を選択して運転可能としているが、熱風のモードでは、強熱風モードのみ運転可能としており、熱風のモードを選択した場合はサブスイッチによる風量弱での運転を禁止し、増風側への切換えはできない構成としている。
【００３９】
すなわち、メインスイッチによる熱風モード選択には条件が課されていることになる。
【００４０】
その条件とは、「サブスイッチが強の位置にある場合に限る」ということであり、サブスイッチが強の位置にあるときのみメインスイッチの熱風モードへの切換操作が可能となり（熱風強モードとなる）、サブスイッチが弱の位置にある場合はメインスイッチの熱風のモードへの切換操作を不能としている。
【００４１】
【実施例】
以下、本発明の実施例を図面を参照しながら具体的に説明する。
【００４２】
図１〜図５に、本実施例に係るヘアドライヤＡを示している。図１及び図２に示すように、ヘアドライヤＡは、前端に吹出口10を形成するとともに、後端に吸込口11を形成した本体ケース１内に発熱装置２と送風装置３とを前後に収納配設している。４は本体ケース１の後端から伸延させた電源コードである。
【００４３】
また、本実施例に係るヘアドライヤＡは、必要に応じて吹出口10に装着可能とした整髪用のアタッチメント９を具備するとともに、アタッチメント着脱ボタン５を本体ケース１の前端近傍に設けている。
【００４４】
本体ケース１は、図３〜図５に示すように、合成樹脂製の上下の二分割ケース1a,1b からなり、両ケース1a,1b を付き合わせて前後方向に細長い略円筒状に構成し、グリップを兼用できる形状としている。
【００４５】
そして、前記アタッチメント着脱ボタン５の後方に本ヘアドライヤＡのスイッチ部Ｓを配設しており、同スイッチ部Ｓに設けたメインスイッチ６とサブスイッチ７を操作して吹出温度及び風量の異なる多段の運転モードを選択できるようにしている。
【００４６】
発熱装置２は、正面視において十字形状の絶縁板20にヒータ線21を巻回してヒータＨを構成し、これを前後方向に長い遮熱筒22に収納して構成している。
【００４７】
また、送風装置３は、ファンモータＭと同モータＭの後端から突出したモータ軸30に固着したファンＦとを具備しており、ファンモータＭのモータケース31の外周面に、前方へ向けて沿うように整流翼32を放射状に配設するとともに、同整流翼32の外周の後端からファンガイド筒33を後方へ向けて一体成形し、同ファンガイド筒33内に前記ファンＦを収納して構成している。34はベルマウス状の整流リングである。
【００４８】
かかる発熱装置２及び送風装置３は、本体ケース１内に組み込まれる前に、図５に示すように、予め前記スイッチ部Ｓ等と結線されるとともに、本体ケース１の後端部に設けたコード引出部40から電力の供給を受けるリード線41を具備しており、同リード線41のコード引出部40側には端子保持筒43を配設し、同端子保持筒43内には図示しない二つの端子を設けている。
【００４９】
上記構成のヘアドライヤＡにおいて、本発明の要旨となるのは、前記ファンＦの回転数が一段アップする直前の運転モード位置で、前記メインスイッチ６の増出力側への操作をロックするロック手段を設けたことにある。
【００５０】
また、かかるロック手段は、前記ヒータＨの発熱量が一段アップする直前の運転モード位置で、前記メインスイッチ６の増出力側への操作をロックすることにも特徴がある。
【００５１】
本実施例におけるスイッチ部Ｓは、図８に示すように、ファンモータＭのＯＮ・ＯＦＦと、ヒータＨの出力を制御して、COOL（冷風）・HAIR CARE （温風）・HIGH（熱風）からなる基本運転モードの順次切換えを行うメインスイッチ６と、ファンモータＭの出力を制御して各基本運転モードにおける風量を増減してターボモード（強）と静音モード（弱）への切換えを行うサブスイッチ７とから構成しており、本体ケース１上の両スイッチ6,7 の側には、各モード名称を表示している。したがって、多様な運転モードを認識しやすく、かつ、発熱量変化を切換操作するメインスイッチ６と、風量変化を切換操作するサブスイッチ６との使い分けで運転モードが区分できるので、運転しながらのスイッチ切換操作も容易となり、使い勝手が良好なものとなっている。
【００５２】
しかも、メインスイッチ６によるHIGHモードへの切換操作は、後述する構成のロック手段によって、サブスイッチ７がターボ（強）側に位置している場合にのみしか行えないものとしているので、前述したように、吹出温度の過剰な上昇を防止した安全なものとなっている。
【００５３】
すなわち、スイッチ部Ｓは、図２〜図８に示すように、電源のＯＮ・ＯＦＦ切換えと前記基本運転モードの切換えを可能としたスライド式のメインスイッチ６と、ファン出力を強弱二段階（ターボモード・静音モード）に切換え可能としたサブスイッチ７とを、本体ケース１の上側分割ケース1a内に収納固定し（図６）、本体ケース１に着脱自在に取付可能に形成したスイッチケース８に、各スイッチ6,7 の操作部としてのメインスイッチ用つまみ（以下「主つまみ」という）60とサブスイッチ用つまみ（以下「副つまみ」という）70とをスライド自在に取付け、さらに、メインスイッチ６の上面に設けた入切用スライド凸部61を、図２及び図３に示すように、主つまみ60の腹側に突設した対向リブ62,62 間に嵌入し、同主つまみ60のスライドに連動するように構成する一方、サブスイッチ７の側面に突設したプッシュ式凸部71を、図２及び図４に示すように、副つまみ70に垂設した操作片72のスライドによって押圧して出没させるように構成している。
【００５４】
そして、図２、図３及び図７に示すように、主つまみ60の係合片60a,60a をスイッチケース８に形成した矩形状のスライド孔8aの両側突状縁8b,8b にスライド自在に係合するとともに、図４、図５及び図７に示すように、スイッチケース８の腹面に副つまみ70のスライド操作に連動する連係板80をスライド自在に配設し、同連係板80を介してメインスイッチ６のロック及びロック解除を可能としている。
【００５５】
すなわち、連係板80は、図５及び図７に示すように、前半部の左右両側に係合用孔81,81 を形成しており、同係合用孔81,81 に、副つまみ70の係合片70a,70a を、スイッチケース８に形成した係合片挿通孔8c,8c を挿通して係合している。
【００５６】
また、両係合用孔81,81 間に矩形状の小切欠部82を形成し、同小切欠部82の後側縁に片持ち支持された弾性片83を小切欠部82内に伸延するともに、同弾性片83の上面に、図２、図４及び図５に示すように、ロック解除部としてのロック解除用ボタン84を突設し、同ボタン84の後方に、図９及び図１０に示すようにロック用係合突起85を形成し、さらに、同係合突起85に対応する係合凹部86をスイッチケース８に形成してロック手段を構成している。このように、本実施例では、ロック手段をスイッチケース８と連係板80とを連係させることで構成している。
【００５７】
また、連係板80の後半部には、主つまみ60の係合片60a,60a の逃げ部分となる矩形状の大切欠部87を形成し、同大切欠部87の前側縁には主つまみ60の係合片 60a,60a に当接するストッパ部88を設けている。
【００５８】
89はクリック機構であり、連係板80の側縁に設けた凸部89a と、スイッチケース８に設けた複数の凹部89b により構成し、サブスイッチ７のスライド操作時にクリック感を生起するようにして操作感を向上させている。
【００５９】
なお、メインスイッチ６においては、図示しないがその内部にクリック機構を設け、主つまみ60の操作時にもクリック感を生起するようにしている。
【００６０】
また、前記ロック解除用ボタン84は、サブスイッチ７の操作部、すなわち副つまみ70に付設した構成となっている。
【００６１】
具体的には、図９及び図１０に示すように、スイッチケース８に設けたボタン挿通孔8dを介して副つまみ70の中央部から突出させ、しかも、図４に示すように、その頂部84a を副つまみ70の最も高い部位よりもさらに上方に位置させているので、使用者が容易に押し下げることができ、適宜、同ロック解除用ボタン84を押し下げてロック用係合突起85を係合凹部86から離脱することにより、ロックを解除することができる。
【００６２】
すなわち、副つまみ70が静音モード（弱）のポジションにあるときは、前記ロック用係合突起85がスイッチケース８に形成された係合凹部86に係合して連係板80はロックされた状態となっており、主つまみ60のスライドはＯＦＦ、COOL（冷風）、HAIR CARE （温風）までの間は自由にスライドして切換動作を行うことができるが（図９参照）、HAIR CARE （温風）からHIGH（熱風）への切換えは、主つまみ60の係合片60a,60a がストッパ部88に当接するのでスライドが禁止されて行えない。
【００６３】
そこで、ロック解除用ボタン84を押下げて副つまみ70をターボモード（強）のポジションにスライド移動させることにより、同副つまみ70のスライドに連動して連係板80も前方へスライドし、前記ストッパ部88と主つまみ60の両係合片60a,60a との間に主つまみ60がスライドできるだけの間隙が形成され、主つまみ60をHIGH（熱風）のポジションへ移動することができる（図１０参照）。
【００６４】
このように、本実施例では、ファンＦの回転数、並びにヒータＨの発熱量を一段アップさせるサブスイッチ７にロック手段を設け、同ロック手段のロック解除用ボタン84を操作しなければファンＦの回転数、並びにヒータＨの発熱量を増加させることができないようにしている。
【００６５】
すなわち、メインスイッチ６の操作において、ファンＦの回転数、並びにヒータＨの発熱量が一段アップする直前の運転モードであるHAIR CARE （温風）モードのポジションにおいて、サブスイッチ７が静音モード（弱）のポジションではメインスイッチ６がロックされ（図８参照）、増出力側、すなわちHIGH（熱風）モードに切換えることがでないようにしており、これを切換え可能とするためには、サブスイッチ７がターボモード（強）のポジションに位置していなければならないようにしている。
【００６６】
また、メインスイッチ６及びロック解除用ボタン84を付設したサブスイッチ７を、本体ケース１の同一面上で近接状態に並設しているので、本ヘアドライヤＡの使用時にロック解除の操作をする場合でも指の移動量が少なくてすみ、使い勝手がより向上するとともに、モードチェンジも行いやすく使い勝手が良い。
【００６７】
さらに、図１、図２、図９及び図１０に示すように、メインスイッチ６（主つまみ60）とアタッチメント着脱ボタン５とを離隔して、その間にサブスイッチ７（副つまみ70）を設けており、しかも、前述したように、副つまみ70に設けたロック解除用ボタン84は、その頂部84a を副つまみ70の最も高い部位よりもさらに上方に位置させ、さらには、ロック解除用ボタン84を、アタッチメント着脱ボタン５の高さよりも高位置となるようにしているので、主つまみ60の操作時に誤って指を前方へ滑らせても副つまみ70及びロック解除用ボタン84が介在しているのでアタッチメント着脱ボタン５を押してしまうことがなく、ヘアドライヤＡの使用中にアタッチメント９が外れたりするおそれがない。
【００６８】
図１１に、本実施例に係るヘアドライヤＡの回路図を示しており、メインスイッチ６は、▲４▼の端子を電源側として、▲１▼、▲２▼、▲３▼、▲５▼の各端子との間の接続状態を切換えることにより、前記したように、COOL（冷風）・HAIR CARE （温風）・HIGH（熱風）の３種類の基本運転モードに順次切換える。
【００６９】
図１１において、ファンモータＭは、全波整流回路35を介して供給される直流電源で駆動され、同全波整流回路35の一方の入力路36はメインスイッチ６の▲１▼端子に直接接続され、他方の入力路37は、中途に、ファンモータＭの回転を制御する245 オームの可変抵抗Ｒと、183 ℃で作動する温度ヒューズ38とを介装し、ヒータ入力路23に接続している。
【００７０】
ヒータ入力路23には、16.1オームのヒータ線21と、110 ℃で作動するサーモスタット24とを介装しており、メインスイッチ６の端子▲２▼、▲３▼とは、一方向の電流通過のみを許すダイオードＤを介して接続するとともに、これと並列に、端子▲５▼と直接接続している。
【００７１】
前記入力路37において、前記可変抵抗Ｒと並列にサブスイッチ７を接続しており、同サブスイッチ７は、常開スイッチであって、このＯＦＦ状態では静音（弱）モードとなっており、これをＯＮ状態に切り換えると、可変抵抗Ｒが一部バイパスされ、全波整流回路35に印加される電圧値が増大しファンモータＭの回転数が上昇してターボ（強）モードとなる。なお、図中、39は第２の温度ヒューズ（110 ℃）、C1は雑音防止用コンデンサ、C2は平滑用コンデンサである。
【００７２】
このように、サブスイッチ７は、基本運転モードの各状態に対してファン出力を制御して風量を増減させる機能を有するが、本実施例では、前述したように、サブスイッチ７がＯＦＦの場合は、ロック手段によって、メインスイッチがHIGH（熱風）のポジションに移動することを禁止している。
【００７３】
また、各運転モード時の端子接続状態を図１２に、各運転モードにおけるモータ出力とヒータ出力の制御状態を図１３に示しており、本実施例では、 COOL(冷風) モードではヒータＨは作動せず、サブスイッチ７の操作によりファン出力を静音（弱：18000r.p.m）・ターボ（強：22000r.p.m）とで切換可能とし、HAIR CARE(温風) モードでは、ヒータ出力が350 Ｗで静音（弱：18000r.p.m) の場合は吹出温度を約95℃、ターボ（強：22000r.p.m）では吹出温度を約70℃となるように設定するとともに、HIGH（熱風) モードでは、ヒータ出力が700 Ｗ、ファンＦの回転数が22000r.p.mで吹出温度を約120 ℃となるようにしている。
【００７４】
このように、本実施例に係るヘアドライヤＡでは、最大のヒータ出力と最大のファン出力とを組合せ可能としているので、同等の出力の送風装置３を有する従来のヘアドライヤと比べて乾燥能力が著しく向上し、髪の乾燥時間を大幅に短縮することができる。
【００７５】
また、ロック手段を設け、メインスイッチ６によるヒータＨの最大出力への切換操作を、サブスイッチ７がファンモータＭの最大出力側に位置している場合にのみ行えるように構成しているので、サブスイッチ７を最大出力側にしておかない限り、使用開始時にメインスイッチ６を操作していきなりヒータ最大出力で運転してしまうことがなく、深夜等に使用する際に、ファンＦの回転による騒音の発生が防止できるとともに、他に電力消費の大きな電気器具が使用されている場合に過剰電流が流れたりするおそれもない。
【００７６】
なお、本実施例では、上述してきたように、基本運転モードをCOOL（冷風）・HAIR CARE （温風）・HIGH（熱風）としたが、COOL（冷風）モードについては必ずしも設定する必要はなく、また、吹出温度を約70℃と約95℃としたHAIR CARE （温風）モードに代えて、ファン出力を低下させて弱風とし、吹出温度を約120 ℃とした一般的に採用されているLOW モードを設定することもできる。
【００７７】
また、ヒータ出力並びにファン出力の切換えは、上記したように２段階とするに限らず、複数段階に切換え可能とすることもできる。
【００７８】
さらに、本実施例では、ヒータ出力の切換手段としてダイオードを用いているが、例えば、出力の異なる複数のヒータ線を選択的に切換える回路構成とすることもでき、その切換手段としては種々考えられる。
【００７９】
ここで、本実施例に係るヘアドライヤＡのその他の構成について説明する。
【００８０】
図２及び図５において、12は二分割ケース1a,1b の吹出口10の外周壁上に挿通する金属製のキャップであり、吹出口10の外周壁後端部に取付けられる締結リング13とともに、二分割ケース1a,1b の前端における突き合わせ状態をより確実に保持できるようにしている。14は前記キャップ12の周壁前端部に内装される補助リングである。
【００８１】
また、二分割ケース1a,1b の後端側においては、その吸込口11の中央に放射状の径方向リブ15で支持された半割形のコード引出口筒42,42 で前記リード線41の端子保持筒43を抱合しており、かかる端子保持筒43に、スイベル式の電源コード４の接点44a,44b （図５）を有する端部を差し込んで、端子保持筒43内の二つの端子に回転自在に接触させている。45はコード引出口筒42の後端内部に設けた係止突起であり、同突起45と係合する環状溝部46を電源コード４の端部に設けて、コード引出口筒42で電源コード４の端部を抱合することにより電源コード４を回転自在に装着している。
【００８２】
また、コード引出口筒42には、傘状に形成した吸込口フィルタ16を取付けており、二分割ケース1a,1b の後端部における締結を図っている。17はメッシュ状のフィルタ部、18は吸込口フィルタ16の取付用筒体である。
【００８３】
次に、本ヘアドライヤＡに着脱自在に装着されるアタッチメント９について説明する。
【００８４】
かかるアタッチメント９としては、複数種の形状のものが用意されているが、その一例として、図１及び図１４に示すようにブラシ形状としたものがある。
【００８５】
このアタッチメント９は、中空状に形成したブラシ本体90に湾曲面を有するシリコンゴム製のベース91を取付け、同ベース91上に多数の植毛体92を植設するとともに、同植毛体92,92 間にスリット状の吹出部93を形成している。図１４中、94はブラシ本体90の中空部内に突設した補強リブである。
【００８６】
しかも、前記ベース91の左右側部には、同ベース91の略全長にわたり髪押さえ用条部95,95 を形成しており、ブラシ本体90を回動したり傾動したりして、所望する状態に整髪する場合、髪押さえ用条部95の先鋭部96により髪をしっかりと押さえつけながら温風又は冷風をあてることにより、所望するカール状態やくせ付けを容易に得ることができるので整髪しやすくなる。なお、髪押さえ用条部95は、本実施例ではベース91と一体成形しているが、別体のものを接着することもできる。
【００８７】
かかるアタッチメント９の取り外しは、前記したようにアタッチメント着脱ボタン５の操作により行うものであって、アタッチメント着脱ボタン５は、図９及び図１０に示すように、ボタン本体50をスイッチケース８の前側部に設けた着脱ボタン挿通孔8e（図５参照）から外方へ突出させるとともに、前記アタッチメント９に係脱するロック爪51を連設しており、ボタン本体50の内部には、基端を遮熱筒22に当接させた付勢ばね52を配設して、ボタン本体50を常に突出付勢している。
【００８８】
（第２実施例）
図１５及び図１６に本発明に係るヘアドライヤＡの第２実施例を示しており、これは、スイッチ部Ｓからサブスイッチ７をなくし、メインスイッチ６によりファンモータＭのＯＮ・ＯＦＦと、各基本運転モードのみの運転を行うようにしたもので、メインスイッチ６のつまみ6aにロック手段を付設したスイッチ部S2としている。
【００８９】
ここでの基本運転モードは、ヒータ出力を停止し、ファン出力を弱としたCOOL（弱冷風）と、ヒータ出力及びファン出力を共に弱とし、吹出温度を約120 ℃とした所謂セットモードであるLOW （弱熱風）と、ヒータ出力及びファン出力を共に強とし、これも吹出温度を約120 ℃とした所謂乾燥モードであるHIGH（強熱風）としており、ＯＦＦからCOOL（弱冷風）、LOW （弱熱風）の各モードのポジション間は、自由に前記つまみ6aのスライドを可能としているが、LOW （弱熱風）モードのポジションに切換えるとロックされて、HIGH（強熱風）モードのポジションにスライドさせるためには、ロック解除用ボタン84を押し下げて、同ボタン84の後方に設けたロック用係合突起85を、スイッチケース８に設けた係合凹部86から離脱しなければならないようにしている。
【００９０】
本実施例においては、ヘアドライヤＡの使用を終えてＯＦＦとした場合、次の使用の際にHIGHモードにするためには必ずロック解除用ボタン84の操作が必要となるので、例えば深夜にヘアドライヤＡを使用する際に、いきなりHIGHモードで運転されることがなく、このHIGHモードによるファンＦの大きな音が騒音となって寝静まった周囲に迷惑をかけることがない。
【００９１】
なお、本実施例における他の構成は第１実施例と同様なのでここでの説明は省略する。
【００９２】
（第３実施例）
さらに、図１７に示した第３実施例に係るヘアドライヤＡのスイッチ部S3について説明する。
【００９３】
これは、メインスイッチ６から電源の入切機能を切り離し、別途、入切スイッチ6'を設けたものである。
【００９４】
メインスイッチ６のつまみ6aの構成は第２実施例と略同様であるが、ここでは、LOW （弱熱風）モードのポジションとHIGH（強熱風）モードのポジションとの間に、先の第１実施例で示したHAIR CARE モードにおいてファン出力を強として風量を増加させた強温風に等しいMEDIUMモードを設定し、同MEDIUMモードのポジションでスイッチ操作がロックされるようにしている。
【００９５】
したがって、本実施例においては、つまみ6aをHIGH（強熱風）モードのポジション以外に位置させて入切スイッチ6'をＯＦＦとしておけば、再使用の際に、いきなりヒータ出力が大のHIGH（強熱風）モードとなることがないので、例えば、電力消費の大きい他の電気製品が同時使用されていても、過剰電流が流れるおそれがなく安全である。
【００９６】
さらに、COOL（冷風）からMEDIUM（強温風）モードまでのいずれかのポジションでＯＦＦとしておけば、そのモードでの使用開始が入切スイッチ6'をＯＮするだけで可能となり、使い勝手が向上する。
【００９７】
なお、本実施例においては、つまみ6aがHIGH（強熱風）モードのポジションにあるときには、入切スイッチ6'がＯＦＦに入らないように構成しておくことが好ましく、かかる構成とすれば、入切スイッチ6'のＯＦＦ時につまみ6aがHIGH（強熱風）モードのポジションにないことを確認する必要がないので安全性がより高まる。
【００９８】
なお、本実施例における他の構成は、第１、第２実施例と同様であるのでここでの説明は省略する。
【００９９】
ところで、上記してきた各実施例では、スイッチ操作を直線方向へのスライド式として説明したが、例えば、図１８に示すように、スイッチ部S4のつまみ6bは回動スライド式の構成としてもよく、要は、メインスイッチ６の操作において、ファンＦの回転数、並びにヒータＨの発熱量が一段アップする直前の運転モードで、ロック手段によりメインスイッチ６の切換操作がロックされて増出力側に切換えできないようにしたものであればよい。
【０１００】
（第４実施例）
次に、第４実施例に係るヘアドライヤＡのスイッチ部S4について、図１９を参照しながら説明する。
【０１０１】
これは、ヒータ出力やファン出力を複数段に切換える場合、連続的な出力可変を行えるようにするとともに、ファン出力が最高出力以外では、メインスイッチ６による操作でヒータ出力が最大となるHIGH（熱風）ポジションに入らないように規制したロック手段を設けたものである。
【０１０２】
すなわち、本実施例に係るスイッチ部S4は、図１９に示すように、ダイヤル式のサブスイッチ7'でファンモータＭの出力を位相制御により電圧可変に構成するとともに、メインスイッチ６は、第２実施例で示したスライド式のものからロック解除用ボタン84を取り除いた構成としている。
【０１０３】
さらに、メインスイッチ６のつまみ6bの下側部に、凸片63を先端に設けた連結板64を連設して、同連結板64を前記つまみ6bと連動させてスライド自在とするとともに、つまみ6bのスライド移動がLOW （弱熱風）ポジションまでは前記凸片63がサブスイッチ7'に当接しないように構成している。
【０１０４】
一方、サブスイッチ7'の周側面には、同スイッチ7'が最高出力のポジションに回転したところで前記凸片63と係合するロック用凹部73を設け、かかる凸片63とロック用凹部73とによりロック手段を構成している。
【０１０５】
すなわち、図１９(a) に示すように、サブスイッチ7'が最高出力のポジション以外であれば、凸片63がサブスイッチ7'の周側面に当接してメインスイッチ６はHIGH（熱風）ポジションには入ることがなく、他方、図１９(b) に示すように、サブスイッチ7'が最高出力のポジションにある場合は、凸片63とロック用凹部73とが対応し、メインスイッチ６はHIGH（熱風）ポジションまでスライド可能となる。
【０１０６】
このように、本実施例では、ヒータ出力の最大出力と組み合わされるファン出力を最大出力に限定しながら、かつ、ヒータ出力が最大以外では、風量の増減を連続的に変化させることができるようにして、好みの風量及び吹出温度で整髪可能としている。
【０１０７】
なお、本実施例における他の構成は、第１実施例と同様であるのでここでの説明は省略する。
【０１０８】
ところで、本実施例では風量の増減、すなわちファン出力を連続的に可変としたが、ファン出力は段階的に変化させ、ヒータ出力を可変としたり、あるいは両者共に連続的に可変とすることもできる。
【０１０９】
（第５実施例）
さらに、第５実施例として、図２０に示したものを説明する。
【０１１０】
これは、図１５及び図１６で示した第２実施例同様に、メインスイッチ６でＯＦＦにすれば、必ずロック機能がはたらき、意識せずともロックができる効果を奏するもので、ここでは、ロック用つまみ84' をメインスイッチ６の前方位置に別途設け、このロック用つまみ84' を操作しなければ、メインスイッチ６をHIGH（熱風）ポジションへはスライドできないようにしている。
【０１１１】
すなわち、メインスイッチ６は、前述した第４実施例のものと同一構成とし、ロック用つまみ84' に、メインスイッチ６のつまみ6bに設けた凸片63のスライド移動を規制するロック片84'aを前記凸片63のスライド方向と直交する方向に連設するとともに、ロック用つまみ84' を付勢する押圧ばね84'bを配設し、前記ロック片84'aを規制方向に常時付勢するように構成している。
【０１１２】
かかる構成により、メインスイッチ６をHIGH（熱風）ポジションへスライドさせるためには、ロック用つまみ84' を押圧ばね84'bに抗してスライドさせなければならないことになる。
【０１１３】
また、メインスイッチ６をＯＦＦにした場合は、押圧ばね84'bの作用でロックつまみ84'aがメインスイッチ６のHIGH（熱風）ポジションへのスライドを規制する位置に移動する。
【０１１４】
このように、本実施例では、使用者は意識することなくロック手段を機能させることができるので、メインスイッチ６のロックを忘れ、いきなりHIGH（熱風）モードで始動させたりするおそれがなくなる。
【０１１５】
【発明の効果】
本発明は上記の形態で実施されるもので、以下の効果を奏する。
【０１１６】
▲１▼請求項１記載の本発明では、それぞれ出力を複数段に切換可能としたヒータとファンとを収納配設した本体ケースに運転モードを切換えるメインスイッチを設け、同スイッチで段階的に切換え操作することにより、多段に設定された運転モードの中から択一的に運転可能としたヘアドライヤにおいて、前記ファンの回転数が一段アップする直前の運転モード位置で、前記メインスイッチの増出力側への操作をロックするロック手段を設けたことにより、例えば深夜などにヘアドライヤを使用する場合、いきなり、ファンの回転数が一段アップした運転状態になることがなく、回転数がアップしたファンの大きな音が騒音となって寝静まった周囲に迷惑をかけたりすることがない。
【０１１７】
▲２▼請求項２記載の本発明では、それぞれ出力を複数段に切換可能としたヒータとファンとを収納配設した本体ケースに運転モードを切換えるメインスイッチを設け、同スイッチで段階的に切換え操作することにより、多段に設定された運転モードの中から択一的に運転可能としたヘアドライヤにおいて、前記ヒータの発熱量が一段アップする直前の運転モード位置で、前記メインスイッチの増出力側への操作をロックするロック手段を設けたことにより、ヘアドライヤを使用する場合、いきなり、ヒータ出力が一段アップした運転状態になることがなく、たとえ他に電力消費の大きな電気製品が同時に使用されていても、過剰電流が流れるおそれがなく安全である。
【０１１８】

BACKGROUND OF THE INVENTION
The present invention relates to a hair dryer, and more particularly to a hair dryer having improved switch operation means for switching operation modes.
[0002]
[Prior art]
Conventionally, a main switch that switches the operation mode is provided in the main body case that houses and arranges the heater and fan, each of which can switch the output to multiple stages, and the main switch is set in multiple stages by switching operation in stages. There are hair dryers that can be operated alternatively from the other driving modes.
[0003]
That is, for example, the COOL (cool air) mode in which the heater is turned off and the fan output is weak, the heater output and the fan output are both weak, the LOW (weak hot air) mode in which the blowout temperature is about 120 ° C, and the heater output In addition, the fan output is made large, and the blowout temperature can be switched to three stages of the HIGH (hot air) mode in which the air volume is increased while being equivalent to the LOW (weak hot air) mode.
[0004]
In addition, for example, as a basic operation mode with a constant air flow, a cool air / hot air / hot air mode is set by increasing / decreasing the heater output, and when each operation mode is selected, the air flow is increased / decreased in each mode. A device provided with a sub-switch to perform is also known.
[0005]
This is because the operation of the main switch is used to switch the heater output to the increase side or decrease side while rotating the fan, and the operation is performed in the basic operation mode such as the cold air mode, the hot air mode, or the hot air mode with different blowing temperatures as described above. However, in each mode, the fan output is switched by operating the sub-switch to increase or decrease the air volume in each basic operation mode.
[0006]
[Problems to be solved by the invention]
However, the above-described conventional hair dryer still has the following problems.
[0007]
That is, in recent years, lifestyles have diversified, and many people take a bath or wash their hair at midnight, and inevitably use a hair dryer at midnight.
[0008]
In addition, high power consumption devices such as air conditioners, microwave ovens, and electromagnetic cooking machines have been widely used in general households.
[0009]
Therefore, in the above-described conventional hair dryer that has only the main switch, when the heater is turned on suddenly in the HIGH (hot air) mode where both the heater output and the fan output are large at the start of use, if this is at midnight, etc. There was a risk that the loud sound of the fans in this HIGH mode would be annoying to the surroundings as a noise.
[0010]
Further, when the above-described high power consumption devices are used at the same time, there is a possibility that the breaker may fall by using a hair dryer (usually about 10 A) that is a higher power consumption device.
[0011]
On the other hand, even if a sub-switch is provided, the same problem occurs when the heater output and the fan output are maximum at the start of use.
[0012]
This was not easy to prevent even if the user was aware that it was late night or that high-power-consumption equipment was being used at the same time.
[0013]
That is, most of the conventional hair dryers usually employ a slide type main switch, and even if a click mechanism is provided for this switch, the heater output and fan output are excessively large during switch operation. This is because there is a risk of entering the mode.
[0014]
An object of this invention is to provide the hair dryer which can solve the said subject.
[0015]
[Means for Solving the Problems]
Therefore, in order to solve the above-mentioned problem, in the present invention according to claim 1, a main switch for switching the operation mode is provided in a main body case that houses and arranges a heater and a fan each capable of switching the output to a plurality of stages. In the hair dryer that can be operated selectively from among the operation modes set in multiple stages by switching operation in stages with the switch, at the operation mode position immediately before the rotation speed of the fan is increased by one stage, Locking means was provided to lock the operation of the main switch to the increased output side.
[0016]
Therefore, for example, when using a hair dryer in the middle of the night, the fan speed does not suddenly increase, and the loud sound of the fan with the increased speed causes noise and disturbs the surroundings. I don't hang it.
[0017]
Further, according to the present invention, the main switch for switching the operation mode is provided in the main body case housing and arranging the heater and the fan, each of which can switch the output to a plurality of stages, and the switching operation is performed step by step with the switch. In the hair dryer that can be operated alternatively from the operation modes set in multiple stages, the operation mode position immediately before the heating value of the heater is increased by one stage is increased to the increased output side of the main switch. Locking means to lock the operation was provided. Therefore, when using a hair dryer, the heater output does not suddenly go up, and even if other electric products with high power consumption are used at the same time, there is no risk of excess current flowing and it is safe. is there.
[0018]
According to a third aspect of the present invention, the main switch is slidable, and the unlocking portion of the locking means is provided separately from the main switch. Therefore, when the main switch is operated at the start of use, the operation is not started in a state where the unlocking unit is erroneously operated at the same time and the heater output and the fan output are suddenly increased.
[0019]
According to a fourth aspect of the present invention, a sub switch for increasing the air volume in each of the operation modes is provided, and an unlocking portion for the locking means is attached to the operation portion of the sub switch. Therefore, since it can be used in various modes, the usability is improved and the operability is improved because the lock can be released when the sub switch is operated. Also, when setting normal hair, the setting force is stronger in the light wind, so the hair is adjusted by operating the main switch, but since the lock release part is attached to the sub switch that increases or decreases the air volume, During the setting of a weak wind by the operation of the switch, the sub switch is operated accidentally to increase the wind, and there is no possibility of blowing the hair set at the corner and disturbing the hair.
[0020]
Moreover, in this invention of Claim 5, the said main switch and the lock release part were arranged in parallel in the proximity | contact state. Therefore, even when performing unlocking operation when using a hair dryer, the amount of finger movement is reduced and the usability is further improved. When the unlocking part is in the sub switch, the sub switch and the main switch are also close to each other. Therefore, the mode can be easily switched and the operability is improved.
[0021]
Further, in the present invention according to claim 6, the main switch and the unlocking portion are arranged side by side along the axial direction of the main body case on the same surface on the front end side of the main body case, and the sub switch is provided. Arranged on the front end side of the body case. Therefore, when using the hair dryer while grasping the main body case, the unlocking portion is in the operation direction of the main switch, so the operability of unlocking is further improved and the operability of the switch becomes better. .
[0022]
Further, in the present invention according to claim 7, the main switch can switch the heater output from the weak mode to the strong mode step by step while driving the fan at a predetermined rotational speed from the power OFF, A cold air mode in which the heater output is turned off is provided between the power-off position and the mode position where the heater output is weak.
[0023]
Therefore, the hair can be set and crushed by properly using between the cold air and the hot air due to the weak wind with strong setting power. In addition, since the operation toward the increased output (strong wind) side is locked, there is no possibility that the strong wind will be blown off in the middle of the setting, and the hair that has been set at the corner will be blown away and disturbed. In this way, when the main switch is operated and set, it can be prevented from entering the increased output side.For example, even when used at midnight, no noise is generated due to the high rotation of the fan, and the surroundings are disturbed. I don't spend it.
[0024]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, a main switch that switches the operation mode is provided in a main body case that houses and arranges a heater and a fan, each of which can switch the output to a plurality of stages, and is set in multiple stages by performing the switching operation step by step with the switch. In the hair dryer that can be operated alternatively from the operation modes that have been set, lock means for locking the operation to the increased output side of the main switch at the operation mode position immediately before the rotational speed of the fan is increased by one step. It is provided.
[0025]
Furthermore, it is possible to provide a lock means for locking the operation of the main switch to the increased output side at the operation mode position immediately before the heating value of the heater is increased by one step.
[0026]
As an embodiment, slides that switch on and off the fan motor that drives the fan and the basic operation mode consisting of cold air, hot air, and hot air that control the heater output and vary the blowout temperature respectively. Main switch and sub-switch that controls the fan motor output to increase / decrease the air volume in each basic operation mode and switch between strong wind mode and weak wind mode to increase the fan output or heater output by one step In addition, the lock means functions when any one of the switches is operated, and a lock release portion for releasing the lock means can be attached to the operation portion of the sub switch.
[0027]
With this embodiment, for example, when a hair dryer is used at midnight, for example, the fan speed is not suddenly increased, and the loud sound of the fan with the increased speed becomes noise. So that there is no trouble in the surroundings, and the heater output does not suddenly increase, so even if other high-power-consumption devices are used at the same time, excess current There is no fear of flowing and it is safe. Moreover, since the lock can be released when the sub switch is operated, the operability is improved.
[0028]
Furthermore, according to this embodiment, under the fan output at a predetermined rotation speed, the heater output is switched by the main switch and the operation is selectively performed in a plurality of basic operation modes with different blowing temperatures. Since the fan output is switched by the sub switch and the operation is possible in the multi-stage operation mode in which the air volume and the blowing temperature are changed, the usability is improved because the operation can be performed in various modes.
[0029]
In addition, the combination of the maximum output of the heater and the maximum output of the fan makes it possible to dry wet hair and the like in a short time using the heater capacity to the maximum.
[0030]
In addition, since the lock release part that releases the locking means is attached to the operation part of the sub switch, the lock release part may be provided separately from the main switch. In addition, the operation is not started when the unlocking unit is accidentally operated at the same time and the heater output and the fan output are suddenly increased.
[0031]
Moreover, when setting normal hair, the setting force is stronger in the light wind, so the hair is adjusted by operating the main switch, but the lock release part is provided independently of the main switch, so the main switch While setting with a weak wind by operating the lock release part by mistake, operate the sub switch to increase the air volume, increase the wind, blow off the hair that was set at the corner while using the hair dryer There is no risk of disturbing the hair.
[0032]
In addition, it is preferable that the main switch and the unlocking unit are arranged in close proximity to each other. With such a configuration, even when the unlocking operation is performed when the hair dryer is used, the movement amount of the finger can be reduced, and the usability is improved. Further, when the lock release unit is in the sub switch, the sub switch and the main switch are also close to each other, so that mode switching can be easily performed and operability is improved. This has the same effect even if the main body case incorporating the heater and fan also serves as a grip as in the present embodiment or has an independent grip.
[0033]
Furthermore, as a preferred embodiment, the main switch and the unlocking portion are arranged side by side along the axial direction of the main body case on the same surface on the front end side of the main body case, and the sub switch is arranged in the main body case. It is good to arrange on the front end side.
[0034]
That is, when using the hair dryer while holding the main body case, the main switch, the sub switch, and the unlocking means are arranged on the same surface of the main body case and along the axial direction of the main body case. Since the unlocking portion is positioned in the operation direction of the main switch, the operability of the switch is further improved.
[0035]
In addition, the main switch can switch the heater output from the weak mode to the strong mode step by step while driving the fan at a predetermined rotational speed from the power OFF, and the power OFF position and the heater output are weak. It is preferable to provide a configuration with a cold air mode in which the heater output is turned off between the mode positions. With this configuration, hair can be set and crushed using cold air and hot air due to the weak wind with strong setting power, and the operation to the increased output (strong wind) side is locked. There is no danger of blowing a strong wind by mistake and blowing the broken hair.
[0036]
Table 1 specifically shows the operation mode of the hair dryer in the present embodiment.
[0037]
[Table 1]

[0038]
As shown in Table 1, the main switch can select the basic operation mode of cold air, hot air, and hot air, and in the selected basic operation mode, the fan output is controlled by the sub switch except for the hot air mode, and the air volume However, in the hot air mode, only the strong air mode can be operated. When the hot air mode is selected, operation with a low air volume by the sub switch is prohibited and increased. The structure cannot be switched to the wind side.
[0039]
That is, a condition is imposed on the hot air mode selection by the main switch.
[0040]
The condition is “only when the sub switch is in the strong position”, and only when the sub switch is in the strong position, the main switch can be switched to the hot air mode (the hot air strong mode and When the sub switch is in the weak position, it is impossible to switch the main switch to the hot air mode.

Is connected via a diode D that allows only the signal, and directly connected to the terminal (5) in parallel therewith.
[0071]
In the input path 37, a sub switch 7 is connected in parallel with the variable resistor R. The sub switch 7 is a normally open switch, and in this OFF state, the silent (weak) mode is set. Is switched to the ON state, the variable resistor R is partially bypassed, the voltage value applied to the full-wave rectifier circuit 35 is increased, the rotational speed of the fan motor M is increased, and the turbo (strong) mode is set. In the figure, 39 is a second thermal fuse (110 ° C.), C1 is a noise prevention capacitor, and C2 is a smoothing capacitor.
[0072]
As described above, the sub switch 7 has a function of increasing / decreasing the air volume by controlling the fan output for each state of the basic operation mode. However, in this embodiment, as described above, the sub switch 7 is OFF. The lock means prohibits the main switch from moving to the HIGH (hot air) position.
[0073]
FIG. 12 shows the terminal connection state in each operation mode, and FIG. 13 shows the motor output and heater output control states in each operation mode. In this embodiment, the heater H operates in the COOL (cold air) mode. The fan output can be switched between silent (weak: 18000r.pm) and turbo (strong: 22000r.pm) by operating the sub switch 7, and the heater output is 350 W in the HAIR CARE mode. For silent (low: 18000r.pm), set the blowout temperature to about 95 ° C. For turbo (high: 22000r.pm), set the blowout temperature to about 70 ° C. In HIGH (hot air) mode, set the heater output.

The hair drying time can be greatly reduced.
[0075]
Further, a lock means is provided so that the switching operation to the maximum output of the heater H by the main switch 6 can be performed only when the sub switch 7 is located on the maximum output side of the fan motor M. Unless the sub switch 7 is set to the maximum output side, the main switch 6 is not operated suddenly at the start of use, and the heater is not operated at the maximum output. Can be prevented, and there is no possibility of excessive current flowing when other electric appliances with high power consumption are used.
[0076]
In this embodiment, as described above, the basic operation mode is COOL (cold air), HAIR CARE (hot air), and HIGH (hot air), but it is not always necessary to set the COOL (cold air) mode. In addition, instead of the HAIR CARE (warm air) mode where the blowing temperature is about 70 ° C and about 95 ° C, it is generally adopted that the fan output is reduced to make the wind weaker and the blowing temperature is about 120 ° C. You can also set the LOW mode.
[0077]
Further, the switching of the heater output and the fan output is not limited to two stages as described above, but can be switched to a plurality of stages.

(Second embodiment)
FIGS. 15 and 16 show a second embodiment of the hair dryer A according to the present invention. This is because the sub-switch 7 is eliminated from the switch section S, and the fan motor M is turned on / off by the main switch 6 and the basics. The operation is performed only in the operation mode, and the switch portion S2 is provided with a lock means attached to the knob 6a of the main switch 6.
[0089]
The basic operation mode here is a so-called set mode in which the heater output is stopped and the fan output is weak, and the heater output and fan output are both weak, and the blowing temperature is about 120 ° C. Both LOW (weak hot air) and heater output and fan output are strong, and this is also called HIGH (strong hot air), which is a so-called drying mode with a blowing temperature of about 120 ° C. The knob 6a can be freely slid between the positions of each mode (weak air), but it is locked when switched to the LOW (weak air) mode position and slides to the HIGH (hot air) mode position. For this purpose, the lock release button 84 is pushed down so that the lock engagement protrusion 85 provided behind the button 84 must be detached from the engagement recess 86 provided in the switch case 8. Yes.
[0090]
In the present embodiment, when the use of the hair dryer A is finished and turned off, the operation of the unlock button 84 is always required to set the HIGH mode in the next use. When using the, it is not suddenly driven in the HIGH mode, and the loud sound of the fan F by the HIGH mode is noisy and does not disturb the surroundings.
[0091]
Since other configurations in the present embodiment are the same as those in the first embodiment, description thereof is omitted here.
[0092]
(Third embodiment)
Furthermore, the switch part S3 of the hair dryer A according to the third embodiment shown in FIG. 17 will be described.
[0093]
In this case, the power on / off function is disconnected from the main switch 6 and a separate on / off switch 6 'is provided.
[0094]
The configuration of the knob 6a of the main switch 6 is substantially the same as that of the second embodiment, but here, the first embodiment is between the position of the LOW (weak hot air) mode and the position of the HIGH (hot air) mode. In the HAIR CARE mode shown in the example, the MEDIUM mode is set equal to the strong warm air with the fan output increased and the air volume increased, and the switch operation is locked at the position of the MEDIUM mode.
[0095]
Therefore, in this embodiment, if the on / off switch 6 ′ is turned OFF by setting the knob 6a to a position other than the HIGH (hot air) mode position, the heater output suddenly becomes high (high intensity) when reused. The hot air mode is not entered, so that, for example, even if another electric product with high power consumption is used at the same time, there is no risk of excess current flowing and it is safe.
[0096]
Furthermore, if it is turned off at any position from COOL (cold air) to MEDIUM (strong hot air) mode, use in that mode can be started simply by turning on / off switch 6 ', improving usability. .
[0097]
In this embodiment, it is preferable that the on / off switch 6 ′ is not turned off when the knob 6a is in the HIGH (hot air) mode position. Since it is not necessary to confirm that the knob 6a is not in the HIGH (hot air) mode position when the switch 6 'is OFF, safety is further increased.
[0098]
In addition, since the other structure in a present Example is the same as that of the 1st, 2nd Example, description here is abbreviate | omitted.
[0099]
By the way, in each of the embodiments described above, the switch operation has been described as a slide type in a linear direction.For example, as shown in FIG. 18, the knob 6b of the switch unit S4 may be configured as a rotary slide type. In short, in the operation mode of the main switch 6, in the operation mode immediately before the rotation speed of the fan F and the heat generation amount of the heater H are increased by one step, the switching operation of the main switch 6 is locked by the locking means and switched to the increased output side. Anything that can not be done.
[0100]
(Fourth embodiment)
Next, switch part S4 of the hair dryer A which concerns on 4th Example is demonstrated, referring FIG.
[0101]

[0103]
Further, a connecting plate 64 provided with a protruding piece 63 is provided at the lower side of the knob 6b of the main switch 6 so that the connecting plate 64 is slidable in conjunction with the knob 6b. The convex piece 63 is configured not to contact the sub switch 7 ′ until the slide movement of 6b is in the LOW (weak hot air) position.
[0104]
On the other hand, on the peripheral side surface of the sub switch 7 ′, there is provided a locking concave portion 73 that engages with the convex piece 63 when the switch 7 ′ is rotated to the highest output position. This constitutes the locking means.
[0105]
That is, as shown in FIG. 19 (a), if the sub switch 7 'is not in the maximum output position, the projecting piece 63 is in contact with the peripheral side surface of the sub switch 7' and the main switch 6 is in the HIGH (hot air) position. On the other hand, as shown in FIG. 19 (b), when the sub switch 7 'is in the highest output position, the convex piece 63 and the locking concave portion 73 correspond to each other, and the main switch 6 is It can slide to the HIGH (hot air) position.
[0106]
As described above, in this embodiment, the fan output combined with the maximum output of the heater is limited to the maximum output, and the increase / decrease in the air volume can be continuously changed when the heater output is other than the maximum. The hair style can be adjusted with the desired air volume and blowing temperature.
[0107]
In addition, since the other structure in a present Example is the same as that of 1st Example, description here is abbreviate | omitted.
[0108]
By the way, in the present embodiment, the increase / decrease of the air volume, that is, the fan output is continuously variable. However, the fan output can be changed stepwise and the heater output can be variable, or both can be continuously variable. .
[0109]
(5th Example)
Further, a fifth embodiment shown in FIG. 20 will be described.
[0110]
As in the second embodiment shown in FIGS. 15 and 16, the lock function always works if the main switch 6 is turned off, and the lock can be effected without being conscious. A knob 84 'is separately provided at the front position of the main switch 6, and the main switch 6 cannot be slid to the HIGH (hot air) position unless the lock knob 84' is operated.
[0111]
That is, the main switch 6 has the same configuration as that of the above-described fourth embodiment, and the lock piece 84'a for restricting the sliding movement of the convex piece 63 provided on the knob 6b of the main switch 6 on the lock knob 84 '. Are arranged in a direction perpendicular to the sliding direction of the convex piece 63, and a pressing spring 84'b for urging the locking knob 84 'is provided, so that the locking piece 84'a is always urged in the regulating direction. It is configured to do.
[0112]
With this configuration, in order to slide the main switch 6 to the HIGH (hot air) position, the locking knob 84 ′ must be slid against the pressing spring 84′b.
[0113]
When the main switch 6 is turned off, the lock knob 84'a moves to a position where the slide of the main switch 6 to the HIGH (hot air) position is restricted by the action of the pressing spring 84'b.
[0114]
Thus, in this embodiment, since the user can make the locking means function without being conscious, there is no possibility of forgetting to lock the main switch 6 and suddenly starting in the HIGH (hot air) mode.
[0115]
