Description

【0001】
【発明の属する技術分野】
本発明は温風と冷風とを同時に吐出し、温風で毛髪の変形を行うと共に冷風で変形した毛髪を固定できるヘアドライヤに関する。
【0002】
【従来の技術】
従来からヘアドライヤは温風を毛髪に当てることで、寝癖を伸ばしたり、毛髪をカールさせたりする癖付けや毛髪の乾燥に利用されている。ところでヘアドライヤによって発生させた温風のみを毛髪に当てた場合、温風の熱によって水素結合を切断し毛髪を一時的に癖付けすることは可能ではあるが、このように癖付けした状態の毛髪を十分に固定するには、温風により熱した毛髪に冷風を当てて再び水素結合させることが必要である。また温風だけを毛髪に当てた場合には毛髪が過乾燥となり、毛髪がぱさついてまとまりのない状態となってしまい、光が当たった時に乱反射して艶があるように見えず、このような過乾燥を防止する意味でも毛髪に冷風を当てる必要がある。上記ヘアドライヤを用いて例えばスイッチを温風から冷風に切り換えて温風で熱した髪に冷風を当てることは可能ではあるが、この場合、温風を作るヒータの予熱等によって冷風が速やかに吐出されず時間がかかってしまい、またスイッチによる温冷風の切換操作が面倒である。
【0003】
上記問題を改善するために近年では温風と冷風を異なる流路から吐出するヘアドライヤが提供されている。この種のヘアドライヤは、図3に示すようにヒータ9を内装した内側流路2と、該内側流路2を囲む外側流路3とを有し、両流路2、3の上流側に設けたファン16により、内側流路2及び外側流路3の夫々の吐出部から温風と冷風とを同時に吐出するものであって、温風と冷風とを同時に吐出することで、毛髪に温風を当てて毛髪の変形や乾燥を行い、この後ヘアドライヤ1′を移動させて、毛髪の温風が当たった部分に冷風を当てて毛髪の固定や、過乾燥の防止を行っていた。(例えば特許文献1)。
【0004】
しかしながら上記特許文献1に示すヘアドライヤ1′は、各流路2、3の吐出部の先端が細く形成されておらず、冷風や温風を毛髪の所望の部位にスポット的に当てることができない。また特に各流路2、3の吐出部の先端が細くなっていないため、吐出部から吐出される温風と冷風とが混じりやすく、これにより温風の温度は低くなり、冷風の温度は高くなってしまい、温風による毛髪の変形や乾燥、冷風による毛髪の固定や過乾燥の防止を効果的に行えない。さらには上記のように温風と冷風とが混じりやすいため、毛髪の温風が当たる部分と冷風が当たる部分との間に、温風と冷風とが混じった中間温度の風が当たる境界部分ができてしまい、これにより温風が当たった部位にヘアドライヤ1′を移動させて冷風を当てる際には、冷風が当たる前に前述の中間温度の風が当たってしまい、温風を当てた後にすぐに冷風を当てることができず、これによっても冷風による効果が小さくなってしまう。
【0005】
また上記特許文献1に示すヘアドライヤの両流路2、3の吐出部の夫々の先端は軸方向において面一であるため、この点からも吐出される温風と冷風とが混じりやすく、上記した温風及び冷風による効果が小さい。

【発明が解決しようとする課題】
本発明は上記の点に鑑みてなされたものであり、その目的とするところは、温度の低い方の空気及び温度の高い方の空気を毛髪の所望の部位に集中的に当てることができ、温度の高い方の空気による毛髪の変形や乾燥、温度の低い方の空気による毛髪の固定や過乾燥の防止を効果的に行えるヘアドライヤを提供することにある。
【0008】
【課題を解決するための手段】
上記課題を解決するために本発明に係るヘアドライヤは、内側流路2及び該内側流路2を囲む外側流路3を有し、内側流路2を流れる空気と、外側流路3を流れる空気との間に、温度差があるモードを備えたヘアドライヤであって、内側流路2を流れる空気の吐出部を先端が細くなった内側ノズル4とし、外側流路3を流れる空気の吐出部を先端が細くなった外側ノズル5とし、内側流路2を温度が高い方の空気が流れる内筒6と、内筒6の下流側に配設された前記内側ノズル4とで構成し、内筒6の下流側端部と内側ノズル4の上流側端部との間に隙間Sを形成し、少なくとも内側ノズル4を合成樹脂にて形成してなることを特徴とするものである。
【0009】
このように内側流路2を流れる空気の吐出部を先端が細くなった内側ノズル4とし、外側流路3を流れる空気の吐出部を先端が細くなった外側ノズル5とすることで、両ノズル4、5の夫々から吐出される温度の低い方の空気である冷風と、温度の高い方の空気である温風と、を毛髪の所望の部位にスポット的に当てることができる。また特に、各流路2、3の吐出部の先端を細くすることで、冷風と温風とが混じり難くなり、これにより温風及び冷風の夫々の温度を適切な温度とでき、温風よる毛髪の変形や乾燥、冷風による毛髪の固定や過乾燥の防止を効果的に行える。さらには冷風と温風とが混じり難いため、毛髪における冷風が当たる部分を温風が当たる部分に隣接させることができ、これによりヘアドライヤ1を移動させることで、温風が当たった部位にすぐに冷風を当てることが可能となり、冷風による毛髪の固定や過乾燥の防止をさらに効果的に行える。また、内側ノズル4を耐熱構造を有する部材とすることなく安価な合成樹脂にて形成することでコストダウンが図れ、しかも内筒6の下流側端部と内側ノズル4の上流側端部との間に隙間Sを形成することで、内側ノズル4の上流側端部に外側流路を流れる温度の低い方の空気を当てることができ、これにより内側ノズル4を耐熱性のない安価な合成樹脂にて形成したにも関わらず、温度の高い方の空気によって前記内側ノズル4が変形したり、溶けたりすることを防止できる。
【0012】
また請求項2請求項1において内側ノズル4を外側ノズル5よりも吐出方向に突出してなることを特徴とするものである。
【0013】
このように内側ノズル4を外側ノズル5よりも吐出方向に突出することで、冷風と温風とがより一層混じり難くなり、これにより温風による毛髪の変形や乾燥、冷風による毛髪の固定や過乾燥の防止をより一層効果的に行える。さらには温度の高い方の空気が吐出される内側ノズル4を突出することで、温風の風量及び風速を充分に維持でき、温風を所望の箇所により一層正確に当てることができ、またこの温風を当てた箇所を基準としてヘアドライヤを移動することで、冷風も所望の箇所に正確に当てることができる。また、温度の高い方の空気を吐出するノズルを外側ノズル5とし、該外側ノズル5を内側ノズルよりも突出させたものと比して、温風と冷風とが一層混じり難くなり、温風よる毛髪の変形や乾燥、冷風による毛髪の固定や過乾燥の防止をより一層効果的に行え、さらには温風の風量及び風速を充分に維持する効果も向上する。
【0016】
また請求項3請求項1又は請求項2において、内筒6の下流側端部と内側ノズル4の上流側端部とを軸方向に離して上記隙間Sを形成してなることを特徴とするものである。
【0017】
このように、内筒6の下流側端部と内側ノズル4の上流側端部とを軸方向に離して上記隙間Sを形成することで、内側ノズル4の上流側端部は内筒6よりも下流側に配されることとなり、これにより内側ノズル4の上流側端部に外側流路を流れる温度の低い方の空気をより多く当てることができ、内側ノズル4の変形や溶けをより一層防止できる。
【0018】
また請求項4は請求項1〜3のいずれか1項において、内側ノズル4の上流側端部の内径が内筒6の下流側端部の外径以上であることを特徴とするものである。
【0019】
このように内側ノズル4の上流側端部の内径を内筒6の下流側端部の外径以上とすることで、内側ノズル4の上流側端部は温度の低い方の空気が流れる箇所に位置することとなり、温度の低い方の空気をより一層内側ノズル4の上流側端部に当てることができ、結果、温度の高い方の空気によって前記合成樹脂にて形成された内側ノズル4が変形したり、溶けたりすることをより一層防止できる。またこのように内側ノズル4の上流側端部の内径を内筒6の下流側端部の外径以上に大きくすることで、温度の高い方の空気から温度の低い方の空気への熱拡散を抑えることができ、温風よる毛髪の変形や乾燥、冷風による毛髪の固定や過乾燥の防止をより一層効果的に行える。
【0020】
また請求項5は請求項1〜4のいずれか1項において、上記空気の吐出方向と同一方向にマイナスイオンを放出するイオン放出部7を備えてなることを特徴とするものである。
【0021】
このように、空気の吐出方向と同一方向にマイナスイオンを放出するイオン放出部7を備えることで、イオン放出部7から放出されたマイナスイオンを毛髪に当てることで、毛髪の艶出しを行える。
【0022】
【発明の実施の形態】
以下本発明の実施形態の一例を図1及び図2に基づいて説明する。ヘアドライヤ1の内部には、上流側端部の開口がヘアドライヤ1の外部に開口する外気吸込口8と連通する内側流路2と、同じく上流側端部の開口が前記外気吸込口8に連通し且つ内側流路2に隣接して内側流路2を囲む外側流路3と、を設けてあり、両流路2、3は二重円筒構造となっている。外側流路3を流れる空気の吐出部及び内側流路を流れる空気の吐出部は同一方向に開口し、外側流路3の吐出部は前記内側流路2の吐出部を囲んでいる。ヘアドライヤ1の内部の両流路2、3よりも上流側には、外気吸込口8から外気を吸い込んで両流路2、3の夫々に送り、各流路2、3の吐出部から空気を同時に吐出する送風手段を設けてあり、そしてヘアドライヤ1は、前記送風手段により内側流路2に流れる空気と、同じく前記送風手段により外側流路3に流れる空気と、の間に温度差があるモードを備えている。詳述すると内側流路2の途中にはヒータ9を設けてあり、外側流路3にはヒータ9を設けておらず、これにより内側流路2にはヒータ9により加温された温度の高い方の空気が流れ、外側流路3にはヒータ9で加温されていない温度の低い方の空気が流れることとなる。
【0023】
以下上記ヘアドライヤ1の具体的構成について説明する。図1(a)に示すようにヘアドライヤ1は、後端部に後方に開口する外気吸込口8及び前端部に前方に開口する開口部10を備えた円筒状のハウジング11で装置本体の外殻を構成している。外気吸込口8及び開口部10はハウジング11の内部に設けた風洞部12にて連通接続してあり、本例の風洞部12は円筒状のハウジング11の内周面部である。ハウジング11の後部にはハンドル部12を下方に一体に突設している。ハンドル部12の内部の上端には後述するイオン発生部14に高電圧を印加する高電圧発生部15を設けている。なお、図中13は電源供給用コードである。
【0024】
風洞部12の内部には、中心線が風洞部12の中心線上に位置する円筒状の内筒6を設けてあり、該内筒6と風洞部12とで二重円筒構造が形成されている。内筒6は耐熱構造を有しており、例えば合成樹脂により形成された円筒状の壁部材と、壁部材の内周側面に積層したマイカシートのような耐熱部材とで構成している。内筒6の下流側の端は風洞部12の下流側の端と軸方向において略同じ位置にあり、詳しくは風洞部12の下流側の端よりも軸方向のやや上流側に位置している。
【0025】
内筒6よりも上流側の風洞部12には送風手段として軸流型のプロペラファンのようなファン16を内装してあり、ファン16の軸芯は内筒6の中心線の延長線上にある。ファン16はハウジング11内部に設けたモータ17により回転駆動するものであって同心円上に均一に風を流しやすい特徴を有している。
【0026】
ハウジング11の開口部10にはハウジング11と別体の二重円筒構造を有するノズル部材18を取付けている。なおノズル部材18は、ハウジング11に着脱自在に取付けたものであっても良いし、またハウジング11と一体に形成されたものであっても良いものとする。
【0027】
ノズル部材18は、外側ノズル5と、外側ノズル5の内側に設けた内側ノズル4とからなり、内側ノズル4と外側ノズル5は軸方向において重複する部分を有している。上記内側ノズル4と外側ノズル5とは合成樹脂により一体に形成されている。これは内側ノズル4及び外側ノズル5を前述した内筒6のように耐熱構造を有する部材により形成せずに安価な合成樹脂にて形成することで、コストダウンが図れるからである。
【0028】
そして本例では前述した内筒6の内部と、該内筒6の下流側に配設した内側ノズル4の内部と、で内側流路2を構成し、内筒6と風洞部12の間の空間部と、外側ノズル5と内側ノズル4との間の空間部と、で外側流路3を構成し、内側ノズル4を内側流路2を流れる空気の吐出部とし、外側ノズル5を外側流路を流れる空気の吐出部としている。さらには内筒6にヒータ9を内装することで、内側流路2を温度の高い方の空気(以下高温の空気と称す)が流れる流路とし、外側流路3を温度の低い方の空気(以下低温の空気と称す)が流れる流路としている。
【0029】
ノズル部材18について詳述すると、図2に示すように内側ノズル4及び外側ノズル5は下流側の端から先端側(下流側)に行く程、内径及び外径が小さくなるように形成されており、先端が細くなっている。内側ノズル4の中心線は外側ノズル5の中心線上に位置し、またこれら内側ノズル4及び外側ノズル5の中心線は内筒6の中心線の延長線上に位置している。外側ノズル5の上流側端部は風洞部12の下流側端部(開口部10)に連通接続してあり、また内筒6の下流側に配設された内側ノズル4の上流側端部と内筒6の下流側端部とは軸方向に離してあり、内筒6の下流側端部と内側ノズル4の上流側端部との間に隙間Sを形成している。両ノズル4、5のうち、高温の空気を吐出する内側ノズル4はその先端部が低温の空気を吐出する外側ノズル5の先端よりも空気の吐出方向に突出している。また図2に示すように内側ノズル4の上流側端部の内径(φX)は内筒6の下流側端部の外径(φY)以上であり、外側ノズル5の上流側の端の径は開口部10の径と同じである。
【0030】
またハウジング11には内側ノズル4から吐出される高温の空気である温風及び外側ノズル5から吐出される低温の空気である冷風の吐出方向と同一方向にマイナスイオンを放出するイオン放出部7を設けている。本例のイオン放出部7は、外側流路3に配設した放電によりマイナスイオンを発生させるイオン発生部14からなり、イオン発生部14にて発生させたマイナスイオンを外側流路3を流れる低温の空気と共に外側ノズル5よりマイナスイオンを放出するものである。勿論上記イオン発生部14によってマイナスイオンを発生させるタイミングは外側流路3に低温の空気が流れている時と同時が望ましい。また本例ではイオン放出部7を上記のイオン発生部14としたが、例えばイオン放出部7を、上流側端部が外側流路3の途中に連通接続し且つ下流側端部が空気の吐出方向と同一方向に開口するイオン吐出口となったイオン用流路と、該イオン用流路の途中に設けたマイナスイオンを発生するイオン発生部とで構成し、イオン吐出口を空気の流れ方向から見て外側流路3の近傍且つ外側に配置し、イオン発生部にて発生したマイナスイオンをイオン用流路を流れる外側流路3から流入した低温の空気と共にイオン吐出口から毛髪に向けて吐出しても良いものとする。またこの場合、イオン用流路の上流側を外側流路3に連通させず、イオン発生部14で発生したマイナスイオンを外側ノズル5から吹き出される空気により誘引しても良いものとする。
【0031】
上記ヘアドライヤ1にて内側ノズル4から高温の空気を吐出し、同時に外側ノズル5から低温の空気を吐出する場合は、図1に示すハンドル部12に設けた電源スイッチ19等の操作部を使用者が操作する。操作部が操作されると、操作部に接続された図示しない制御部は上述したヒータ9をONにすると共にモータ17をONにする。モータ17の駆動によりファン16が回転すると、外気吸込口8から風洞部12内に外気を吸い込み、風洞部12内に吸い込んだ空気を、内側流路2及び外側流路3の夫々に送り、内側流路2では空気をヒータ9により加熱した後、この加熱された空気を内側ノズル4から吐出し、外側流路3ではヒータ9により空気の加熱を行わずそのまま空気を外側ノズル5(詳しくは外側ノズル5と内側ノズル4の間)から吐出し、これにより高温の空気と、低温の空気とを各ノズル4、5から同時に吐出することができる。そしてこの外側ノズル5から吐出される温風と、該温風と同時に吐出される内側ノズル4から吐出される冷風と、を毛髪に当てることで、まず毛髪の所望の部位に温風を当てて毛髪の変形や乾燥を行い、この後ヘアドライヤ1を移動させて(又は向きを変えて)、前記毛髪の温風が当たった部分に冷風を当てて毛髪の固定や、過乾燥の防止を行い、以下ヘアドライヤ1を移動させて上記の動作を繰り返す。
【0032】
ここで内側ノズル4及び外側ノズル5は前述したように先端が細くなった形状であるため、冷風及び温風を毛髪の所望する部位に集中的に当てることができる。これにより細やかな毛髪の癖付けを行うことができ、さらには毛髪の所望する部位に当たる冷風及び温風の風量を増やすことができ、温風による毛髪の変形及び冷風による毛髪の固定を効果的に行って癖付けすることができ、また温風による毛髪の乾燥、冷風による毛髪の過乾燥防止も効果的に行うことができる。また特に、外側ノズル5及び内側ノズル4の先端を細くすることで、冷風と温風とが混じり難くなり、温風及び冷風の夫々の温度を適切な温度とでき、上記した温風よる毛髪の変形や乾燥、冷風による毛髪の固定や過乾燥の防止をより一層効果的に行える。さらにはこのように冷風と温風とが混じり難いため、従来のように毛髪の温風が当たる部分と冷風が当たる部分との間に、温風と冷風とが混じった中間温度の風が当たる境界部分ができ難く、毛髪における冷風が当たる部分を温風が当たる部分に隣接させることができ、これによりヘアドライヤ1を移動させることで、温風が当たった部位にすぐに冷風を当てることが可能となり、冷風による毛髪の固定や過乾燥の防止をさらに効果的に行える。また上記では温風が流れるノズルを外側ノズル5によって囲まれる内側ノズル4としてあるので、温風及び冷風を同時に吐出したヘアドライヤ1をどちらの方向に移動させたり、向きを変えても、温風を当てた毛髪に冷風を当てることができる。
【0033】
また両ノズル4、5のうち、高温の空気を吐出する内側ノズル4を冷風を吐出する外側ノズル5よりも吐出方向に突出することで、冷風と温風とがより一層混じり難くなり、これにより上記した温風による毛髪の変形や乾燥、冷風による毛髪の固定や過乾燥の防止をより一層効果的に行える。またこの場合、温風の風量及び風速を充分に維持でき、温風を所望の箇所により正確に当てることができ、またこの温風を当てた箇所を基準としてヘアドライヤ1を移動することで、冷風も所望の箇所に正確に当てることができる。さらには内側ノズル4を高温の空気を吐出するものとし、該内側ノズル4を外側ノズル5よりも吐出方向に突出することで、高温の空気を吐出するノズルを外側ノズル5としたものと比して、温風と冷風とが一層混じり難くなり、温風による毛髪の変形や乾燥、冷風による毛髪の固定や過乾燥の防止をより一層効果的に行え、さらには温風の風量及び風速を充分に維持する効果も向上する。
【0034】
また内筒6の下流側端部と内側ノズル4の上流側端部との間に隙間Sを形成することで、内側ノズル4の上流側端部に低温の空気を当てることができ、これにより内側ノズル4を耐熱性のない安価な合成樹脂にて形成したにも関わらず、高温の空気やヒータ9の熱によって前記内側ノズル4が変形したり、溶けたりすることを防止できる。さらには内筒6の下流側端部と内側ノズル4の上流側端部とを軸方向に離して上記隙間Sを形成することで、内側ノズル4の上流側端部は内筒6よりも下流側に配されることとなり、これにより内側ノズル4の上流側端部に低温の空気をより多く当てることができ、上記の内側ノズル4の変形や溶けをより一層防止できる。
【0035】
また内側ノズル4の上流側端部の内径を内筒6の下流側端部の外径以上に大きくすることで、内側ノズル4の上流側端部は低温の空気が流れる箇所に位置することとなり、低温の空気をより一層内側ノズル4の上流側端部に当てることができ、結果、高温の空気やヒータ9の熱によって合成樹脂にて形成された内側ノズル4が変形したり、溶けたりすることをより一層防止できる。またこのように内側ノズル4の上流側端部の内径を内筒6の下流側端部の外径以上に大きくすることで、高温の空気から低温の空気への熱拡散を抑えることができ、温風よる毛髪の変形や乾燥、冷風による毛髪の固定や過乾燥の防止をより一層効果的に行える。
【0036】
また本例では操作部を操作することで、前述したイオン放出部7によって、上記冷風及び温風の吐出と同時にマイナスイオンを毛髪に向けて放出するモードを有している。このモードにてヘアドライヤ1を運転することで、イオン放出部7から放出されたマイナスイオンを毛髪に当てて毛髪の艶を出すことができ、しかもこのマイナスイオンは過乾燥状態となった毛髪に当てられるのではなく、冷風の効果によりぱさつきのなくなった毛髪に当てられるため、マイナスイオンによる艶出し効果がより一層向上する。
【0037】
ここでマイナスイオンを温風ではなく冷風と共に放出するのは以下の理由による。即ち温風と共にマイナスイオンを放出した場合、マイナスイオンに含まれる水分子が加熱されてしまい、毛髪に当ててもすぐに蒸散してしまい、結果、マイナスイオンによる毛髪の艶出し効果が小さいという問題が生じるのだが、本例ではイオン放出部7にてマイナスイオンを冷風と共に放出しているため、マイナスイオンが温風により加熱され難くて蒸散せず、さらに艶出し効果が向上するのである。
【0038】
なお上記ヘアドライヤ1は少なくとも、内側流路2を流れる空気と、外側流路3を流れる空気との間に、温度差があるモード、即ち前述した温風及び冷風を同時に吹き出すモードを有していれば良いものとするが、例えばこの温度差があるモードの他に、前述した温風及び冷風と同時にマイナスイオンを放出するモードや、またヒータ9のON/OFF、モータ17のON/OFF、イオン発生部14のON/OFFを自動的に設定された値に切り換えるその他のモードを有し、操作部の操作によりモードを切り換えられるようにしても構わない。
【0040】
また、本例のヘアドライヤ1は、各流路2、3にヒータ9を設けるか否かにより各流路2、3に流れる空気が温度差を有するものとしたが、例えば各流路2、3に夫々ヒータ9を設け、該ヒータ9のON/OFFの切り換えや、ヒータ9の出力変化により、各流路2、3に流れる空気が温度差を有するものとしても良い。
【0041】
【発明の効果】
以上説明したように本発明のヘアドライヤは、温度の低い方の空気及び温度の高い方の空気を毛髪の所望の部位に集中的に当てることができ、温度の高い方の空気による毛髪の変形や乾燥、温度の低い方の空気による毛髪の固定や過乾燥の防止を効果的に行うことができる。また、内側ノズルを耐熱構造を有する部材とすることなく安価な合成樹脂にて形成することでコストダウンが図れ、しかも内筒の下流側端部と内側ノズルの上流側端部との間に隙間を形成することで、内側ノズルの上流側端部に外側流路を流れる温度の低い方の空気を当てることができ、これにより内側ノズルを耐熱性のない安価な合成樹脂にて形成したにも関わらず、温度の高い方の空気によって前記内側ノズルが変形したり、溶けたりすることを防止できる。

BACKGROUND OF THE INVENTION
The present invention relates to a hair dryer that discharges hot air and cold air at the same time, deforms the hair with hot air, and can fix the hair deformed with cold air.
[0002]
[Prior art]
Conventionally, hair dryers have been used for hairbrushing and drying hair by applying warm air to the hair to stretch the bed and curl the hair. By the way, when only hot air generated by a hair dryer is applied to the hair, it is possible to cut the hydrogen bond and heat the hair temporarily with the heat of the hot air. In order to sufficiently fix the hair, it is necessary to apply hydrogen bonding to the hair heated by warm air by applying cold air to the hair. In addition, when only warm air is applied to the hair, the hair becomes over-dried, and the hair becomes clumsy and uncohered, and it does not appear glossy due to irregular reflection when exposed to light. In order to prevent overdrying, it is necessary to apply cold air to the hair. It is possible to apply cold air to hair heated with warm air by switching the switch from warm air to cold air using the above hair dryer, but in this case, cold air is quickly discharged by preheating the heater that creates the warm air. It takes a long time, and the switching operation of hot and cold air by a switch is troublesome.
[0003]
In order to improve the above problems, hair dryers that discharge hot air and cold air from different flow paths have been provided in recent years. As shown in FIG. 3, this type of hair dryer has an inner flow path 2 with a heater 9 and an outer flow path 3 surrounding the inner flow path 2, and is provided upstream of both flow paths 2 and 3. The fan 16 discharges hot air and cold air simultaneously from the discharge portions of the inner flow path 2 and the outer flow path 3, respectively. The hair was deformed and dried by applying the hair, and then the hair dryer 1 'was moved, and cold air was applied to the portion of the hair that was hit by hot air to fix the hair and prevent overdrying. (For example, patent document 1).
[0004]
However, in the hair dryer 1 ′ shown in Patent Document 1, the tips of the discharge portions of the channels 2 and 3 are not formed thin, and it is impossible to spot cold air or hot air on a desired part of the hair. Moreover, since the tip of the discharge part of each flow path 2 and 3 is not particularly thin, hot air and cold air discharged from the discharge part are likely to be mixed, thereby reducing the temperature of the hot air and increasing the temperature of the cold air. As a result, the hair cannot be deformed or dried by hot air, and the hair can be fixed or prevented from being overdried by cold air. Furthermore, as described above, since warm air and cold air are likely to be mixed, there is a boundary portion between the portion where the hot air hits the hair and the portion where the cold air hits, and the boundary where the wind of intermediate temperature where hot air and cold air are mixed hits. Therefore, when the hair dryer 1 'is moved to the area where the hot air hits and the cold air is applied, the intermediate temperature wind hits before the cold air hits, and immediately after the hot air is applied. The cold wind cannot be applied to this, and this also reduces the effect of the cold wind.
[0005]
In addition, since the tips of the discharge portions of both flow passages 2 and 3 of the hair dryer shown in Patent Document 1 are flush with each other in the axial direction, the hot air and the cold air discharged from this point are also likely to be mixed. The effect of warm air and cold air is small.

[Problems to be solved by the invention]
The present invention has been made in view of the above points, and the object of the present invention is that the lower temperature air and the higher temperature air can be concentrated on a desired part of the hair, An object of the present invention is to provide a hair dryer capable of effectively preventing deformation and drying of hair by air having a higher temperature, fixing of hair by air having a lower temperature, and prevention of overdrying.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, a hair dryer according to the present invention has an inner channel 2 and an outer channel 3 surrounding the inner channel 2, and air flowing in the inner channel 2 and air flowing in the outer channel 3. A hair dryer having a mode with a temperature difference between the two and the air discharge portion flowing through the inner flow path 2 as an inner nozzle 4 having a narrow tip, and the air discharge portion flowing through the outer flow path 3 An outer nozzle 5 having a thin tip is formed, and the inner flow path 2 is constituted by an inner cylinder 6 through which air having a higher temperature flows and the inner nozzle 4 disposed on the downstream side of the inner cylinder 6. 6, a gap S is formed between the downstream end of 6 and the upstream end of the inner nozzle 4, and at least the inner nozzle 4 is formed of synthetic resin .
[0009]
In this way, the discharge part of the air flowing through the inner flow path 2 is the inner nozzle 4 having a narrow tip, and the discharge part of the air flowing through the outer flow path 3 is the outer nozzle 5 having a thin tip, both nozzles The cool air that is the lower temperature air discharged from each of 4 and 5 and the hot air that is the higher temperature air can be spotted on the desired part of the hair. In particular, by making the tips of the discharge portions of the respective flow paths 2 and 3 narrow, it becomes difficult to mix the cold air and the hot air, whereby the temperature of each of the hot air and the cold air can be set to an appropriate temperature. It can effectively prevent hair deformation and drying, fixing of hair by cold air, and overdrying. Furthermore, since it is difficult for cold air and hot air to mix, the portion of the hair that is exposed to the cold air can be adjacent to the portion that is exposed to the hot air, so that by moving the hair dryer 1, the portion immediately exposed to the hot air It becomes possible to apply cold air, and it is possible to more effectively prevent the hair from being fixed and overdried by the cold air. Further, the inner nozzle 4 can be made of an inexpensive synthetic resin without using a member having a heat resistant structure, and the cost can be reduced, and the downstream end of the inner cylinder 6 and the upstream end of the inner nozzle 4 can be reduced. By forming the gap S between them, the lower temperature air flowing through the outer flow path can be applied to the upstream end of the inner nozzle 4, thereby making the inner nozzle 4 an inexpensive synthetic resin that is not heat resistant. In spite of being formed by the above, it is possible to prevent the inner nozzle 4 from being deformed or melted by the higher temperature air.
[0012]
A second aspect is characterized in that , in the first aspect , the inner nozzle 4 protrudes in the ejection direction from the outer nozzle 5.
[0013]
By projecting the inner nozzle 4 in the ejection direction from the outer nozzle 5 in this way, it becomes more difficult for cold air and hot air to be mixed, thereby deforming and drying the hair with hot air, fixing and overloading the hair with cold air. Drying can be prevented more effectively. Furthermore, by projecting the inner nozzle 4 through which the higher temperature air is discharged, the air volume and the air speed of the hot air can be sufficiently maintained, and the hot air can be more accurately applied to a desired location. By moving the hair dryer on the basis of the location where the hot air is applied, the cold air can also be accurately applied to the desired location. Further, the nozzle that discharges the air having the higher temperature is the outer nozzle 5, and the hot air and the cold air are less likely to be mixed as compared with the outer nozzle 5 that protrudes from the inner nozzle. Hair deformation and drying, fixing of hair by cold air and prevention of overdrying can be performed more effectively, and the effect of sufficiently maintaining the air volume and wind speed of hot air is also improved.
[0016]
A third aspect is characterized in that, in the first or second aspect , the gap S is formed by separating the downstream end of the inner cylinder 6 and the upstream end of the inner nozzle 4 in the axial direction. To do.
[0017]
In this way, the downstream end of the inner cylinder 6 and the upstream end of the inner nozzle 4 are separated in the axial direction to form the gap S, so that the upstream end of the inner nozzle 4 is more than the inner cylinder 6. Is also arranged on the downstream side, so that it is possible to apply more air having a lower temperature flowing through the outer flow path to the upstream end portion of the inner nozzle 4, thereby further deforming and melting the inner nozzle 4. Can be prevented.
[0018]
The fourth aspect which is characterized in that an equal to or greater than the outer diameter of the downstream end of claim any Oite to one of claims 1 to 3, the upstream end of the inner diameter inner cylinder 6 of the inner nozzle 4 It is.
[0019]
In this way, by setting the inner diameter of the upstream end portion of the inner nozzle 4 to be equal to or larger than the outer diameter of the downstream end portion of the inner cylinder 6, the upstream end portion of the inner nozzle 4 is located at a location where air having a lower temperature flows. Therefore, the lower temperature air can be further applied to the upstream end of the inner nozzle 4, and as a result, the inner nozzle 4 formed of the synthetic resin is deformed by the higher temperature air. It can be further prevented from melting or melting. In addition, by increasing the inner diameter of the upstream end of the inner nozzle 4 to be larger than the outer diameter of the downstream end of the inner cylinder 6, heat diffusion from the higher temperature air to the lower temperature air is performed. The hair can be prevented from being deformed and dried by hot air, and the hair can be fixed and prevented from being overdried by cold air.
[0020]
A fifth aspect of the present invention is characterized in that in any one of the first to fourth aspects, an ion emission part 7 that emits negative ions in the same direction as the air discharge direction is provided.
[0021]
Thus, by providing the ion emission part 7 which discharge | releases a negative ion in the same direction as the discharge direction of air, it can polish hair by making the negative ion discharge | released from the ion discharge | release part 7 hit against hair.
[0022]

[0023]
Hereinafter, a specific configuration of the hair dryer 1 will be described. As shown in FIG. 1 (a), a hair dryer 1 includes a cylindrical housing 11 having an outside air inlet 8 that opens rearward at the rear end and an opening 10 that opens forward at the front end. Is configured. The outside air inlet 8 and the opening 10 are connected in communication with a wind tunnel 12 provided inside the housing 11, and the wind tunnel 12 in this example is an inner peripheral surface of the cylindrical housing 11. A handle portion 12 is integrally projected downward from the rear portion of the housing 11. A high voltage generator 15 for applying a high voltage to an ion generator 14 described later is provided at the upper end inside the handle portion 12. In the figure, reference numeral 13 denotes a power supply cord.
[0024]
A cylindrical inner cylinder 6 whose center line is located on the center line of the wind tunnel part 12 is provided inside the wind tunnel part 12, and the inner cylinder 6 and the wind tunnel part 12 form a double cylindrical structure. . The inner cylinder 6 has a heat resistant structure, and is composed of, for example, a cylindrical wall member made of synthetic resin and a heat resistant member such as a mica sheet laminated on the inner peripheral side surface of the wall member. The downstream end of the inner cylinder 6 is substantially in the same axial position as the downstream end of the wind tunnel portion 12, and more specifically, is located slightly upstream in the axial direction from the downstream end of the wind tunnel portion 12. .
[0025]
A fan 16 such as an axial flow type propeller fan is provided as an air blowing means in the wind tunnel portion 12 upstream of the inner cylinder 6, and the axis of the fan 16 is on an extension of the center line of the inner cylinder 6. . The fan 16 is rotationally driven by a motor 17 provided inside the housing 11 and has a feature that it is easy to allow air to flow uniformly on a concentric circle.
[0026]
A nozzle member 18 having a double cylindrical structure separate from the housing 11 is attached to the opening 10 of the housing 11. The nozzle member 18 may be detachably attached to the housing 11 or may be formed integrally with the housing 11.
[0027]
The nozzle member 18 includes an outer nozzle 5 and an inner nozzle 4 provided inside the outer nozzle 5, and the inner nozzle 4 and the outer nozzle 5 have overlapping portions in the axial direction. The inner nozzle 4 and the outer nozzle 5 are integrally formed of synthetic resin. This is because the inner nozzle 4 and the outer nozzle 5 are not formed of a member having a heat-resistant structure like the inner cylinder 6 described above, but formed of an inexpensive synthetic resin, thereby reducing the cost.
[0028]
And in this example, the inner flow path 2 is comprised by the inside of the inner cylinder 6 mentioned above and the inside of the inner nozzle 4 arrange | positioned in the downstream of this inner cylinder 6, and between the inner cylinder 6 and the wind tunnel part 12 is comprised. The space portion and the space portion between the outer nozzle 5 and the inner nozzle 4 constitute the outer flow path 3, the inner nozzle 4 serves as an air discharge portion that flows through the inner flow path 2, and the outer nozzle 5 flows to the outer flow path. It is a discharge part for air flowing through the road. Further, by installing a heater 9 in the inner cylinder 6, the inner flow path 2 is used as a flow path through which the higher temperature air (hereinafter referred to as high temperature air) flows, and the outer flow path 3 is used as the lower temperature air. The flow path (hereinafter referred to as low temperature air) flows.
[0029]
The nozzle member 18 will be described in detail. As shown in FIG. 2, the inner nozzle 4 and the outer nozzle 5 are formed so that the inner diameter and the outer diameter become smaller from the downstream end toward the distal end side (downstream side). The tip is thin. The center line of the inner nozzle 4 is located on the center line of the outer nozzle 5, and the center lines of the inner nozzle 4 and the outer nozzle 5 are located on the extension line of the center line of the inner cylinder 6. The upstream end portion of the outer nozzle 5 is connected to the downstream end portion (opening portion 10) of the wind tunnel portion 12, and is connected to the upstream end portion of the inner nozzle 4 disposed on the downstream side of the inner cylinder 6. The downstream end of the inner cylinder 6 is separated in the axial direction, and a gap S is formed between the downstream end of the inner cylinder 6 and the upstream end of the inner nozzle 4. Among the nozzles 4 and 5, the inner nozzle 4 that discharges high-temperature air has a tip protruding in the air discharge direction from the tip of the outer nozzle 5 that discharges low-temperature air. As shown in FIG. 2, the inner diameter (φX) of the upstream end of the inner nozzle 4 is equal to or larger than the outer diameter (φY) of the downstream end of the inner cylinder 6, and the diameter of the upstream end of the outer nozzle 5 is It is the same as the diameter of the opening 10.
[0030]
Further, the housing 11 has an ion emitting portion 7 that emits negative ions in the same direction as the discharge direction of hot air that is high-temperature air discharged from the inner nozzle 4 and cold air that is low-temperature air discharged from the outer nozzle 5. Provided. The ion emission part 7 of this example is composed of an ion generation part 14 that generates negative ions by discharge disposed in the outer flow path 3, and the low temperature of the negative ions generated by the ion generation part 14 flowing through the outer flow path 3. The negative ions are discharged from the outer nozzle 5 together with the air. Of course, it is desirable that the negative ion is generated by the ion generator 14 at the same time as when low-temperature air is flowing in the outer flow path 3. In this example, the ion emission part 7 is the above-described ion generation part 14. For example, the ion emission part 7 is connected to the upstream end part in the middle of the outer flow path 3 and the downstream end part discharges air. The ion flow path is an ion discharge port that is opened in the same direction as the direction, and an ion generation unit that generates negative ions provided in the middle of the ion flow path. The negative ions generated in the ion generating part are disposed near and outside the outer flow channel 3 when viewed from the ion discharge port toward the hair together with the low-temperature air flowing in from the outer flow channel 3 flowing through the ion flow channel. It may be discharged. In this case, the upstream side of the ion channel is not communicated with the outer channel 3, and negative ions generated by the ion generator 14 may be attracted by the air blown from the outer nozzle 5.
[0031]
When the hair dryer 1 discharges high-temperature air from the inner nozzle 4 and simultaneously discharges low-temperature air from the outer nozzle 5, an operation unit such as a power switch 19 provided on the handle unit 12 shown in FIG. Operate. When the operation unit is operated, a control unit (not shown) connected to the operation unit turns on the heater 9 and turns on the motor 17. When the fan 16 is rotated by driving the motor 17, the outside air is sucked into the wind tunnel portion 12 from the outside air suction port 8, and the air sucked into the wind tunnel portion 12 is sent to each of the inner flow path 2 and the outer flow path 3. In the flow path 2, the air is heated by the heater 9, and then the heated air is discharged from the inner nozzle 4. In the outer flow path 3, the air is not heated by the heater 9 and the air is left as it is for the outer nozzle 5 (more specifically, the outer side From between the nozzle 5 and the inner nozzle 4), high-temperature air and low-temperature air can be discharged simultaneously from the nozzles 4, 5. The hot air discharged from the outer nozzle 5 and the cool air discharged from the inner nozzle 4 discharged simultaneously with the hot air are applied to the hair, so that the hot air is first applied to a desired part of the hair. The hair is deformed and dried, and then the hair dryer 1 is moved (or changed in direction), and the air is applied to the portion where the hot air is applied to fix the hair and prevent overdrying. Thereafter, the hair dryer 1 is moved and the above operation is repeated.
[0032]
Here, since the inner nozzle 4 and the outer nozzle 5 have a shape with a thin tip as described above, it is possible to concentrate cold air and hot air on a desired portion of the hair. As a result, it is possible to finely braze the hair, further increase the amount of cold air and hot air hitting the desired part of the hair, effectively deforming the hair by hot air and fixing the hair by cold air In addition, the hair can be brazed, and the hair can be effectively dried by hot air and the hair can be prevented from being excessively dried by cold air. In particular, by slimming tip of the outer nozzle 5 and an inner nozzle 4, hardly mixed and the cool air and the warm air, can the temperature of each of the warm air and cold air to a suitable temperature, the hair with the hot air as described above Deformation, drying, hair fixation by cold air and prevention of overdrying can be more effectively performed. Furthermore, since it is difficult to mix cold air and hot air in this way, an intermediate temperature wind in which hot air and cold air are mixed hits between the portion where the hot air hits the hair and the portion where the cold air hits as in the past. It is difficult to create the boundary part, and the part where the cool air hits the hair can be adjacent to the part where the hot air hits. By moving the hair dryer 1, it is possible to immediately apply the cool air to the part where the hot air hits. Thus, fixing of hair by cold air and prevention of overdrying can be performed more effectively. Further, in the above, the nozzle through which the hot air flows is the inner nozzle 4 surrounded by the outer nozzle 5, so that the hot air can be moved regardless of the direction in which the hair dryer 1 that simultaneously discharges the hot air and the cold air is moved. Cold air can be applied to the applied hair.
[0033]
Further, of the two nozzles 4 and 5, the inner nozzle 4 that discharges high-temperature air protrudes in the discharge direction from the outer nozzle 5 that discharges cold air, so that the cold air and the hot air are less likely to be mixed. It is possible to more effectively prevent the hair from being deformed and dried by the warm air and the hair from being fixed and overdried by the cold air. In this case, the air volume and the speed of the hot air can be sufficiently maintained, the hot air can be applied more accurately at a desired location, and the hair dryer 1 is moved with reference to the location where the hot air is applied. Can be accurately applied to a desired location. Furthermore, it is assumed that the inner nozzle 4 discharges high-temperature air, and the inner nozzle 4 protrudes in the discharge direction from the outer nozzle 5 so that the nozzle that discharges high-temperature air is the outer nozzle 5. The hot air and cold air are more difficult to mix, and the hair can be deformed and dried by hot air, the hair can be fixed and prevented from overdrying by the cold air, and the amount and speed of the hot air is sufficient. The effect of maintaining the above is also improved.
[0034]
Further, by forming a gap S between the downstream end portion of the inner cylinder 6 and the upstream end portion of the inner nozzle 4, low temperature air can be applied to the upstream end portion of the inner nozzle 4. Even though the inner nozzle 4 is formed of an inexpensive synthetic resin having no heat resistance, the inner nozzle 4 can be prevented from being deformed or melted by high-temperature air or the heat of the heater 9. Furthermore, the downstream end of the inner cylinder 6 and the upstream end of the inner nozzle 4 are separated in the axial direction to form the gap S, so that the upstream end of the inner nozzle 4 is downstream of the inner cylinder 6. As a result, more of the low-temperature air can be applied to the upstream end portion of the inner nozzle 4, and deformation and melting of the inner nozzle 4 can be further prevented.
[0035]
Further, by making the inner diameter of the upstream end of the inner nozzle 4 larger than the outer diameter of the downstream end of the inner cylinder 6, the upstream end of the inner nozzle 4 is located at a location where low temperature air flows. Further, the low temperature air can be further applied to the upstream end of the inner nozzle 4, and as a result, the inner nozzle 4 formed of synthetic resin is deformed or melted by the high temperature air or the heat of the heater 9. This can be further prevented. In addition, by increasing the inner diameter of the upstream end of the inner nozzle 4 to be greater than or equal to the outer diameter of the downstream end of the inner cylinder 6, heat diffusion from high temperature air to low temperature air can be suppressed. Deformation and drying of hair by hot air, fixing of hair by cold air and prevention of overdrying can be performed more effectively.
[0036]
Further, in this example, there is a mode in which negative ions are released toward the hair simultaneously with the discharge of the cold air and the hot air by the above-described ion emission unit 7 by operating the operation unit. By operating the hair dryer 1 in this mode, the negative ions released from the ion release unit 7 can be applied to the hair to make the hair gloss, and the negative ions can be applied to the overdried hair. Since it is applied to the hair that is not crisp due to the effect of cold air, the glossing effect by negative ions is further improved.
[0037]
Here, the negative ions are released together with the cold air instead of the hot air for the following reason. That is, when negative ions are released together with warm air, water molecules contained in the negative ions are heated and transpiration immediately even when applied to the hair. As a result, the effect of shining the hair by the negative ions is small. However, in this example, since the negative ions are released together with the cold air by the ion emission part 7, the negative ions are not easily heated by the hot air and are not evaporated, and the polishing effect is further improved.
[0038]
The hair dryer 1 has at least a mode in which there is a temperature difference between the air flowing through the inner flow path 2 and the air flowing through the outer flow path 3, that is, a mode in which the above-described hot air and cold air are blown out simultaneously. For example, in addition to the mode having this temperature difference, a mode in which negative ions are released simultaneously with the above-described hot air and cold air, heater 9 ON / OFF, motor 17 ON / OFF, ion There may be another mode in which ON / OFF of the generation unit 14 is automatically switched to a set value, and the mode may be switched by operation of the operation unit.
[0040]
Further, in the hair dryer 1 of the present example, the air flowing through the flow paths 2 and 3 has a temperature difference depending on whether or not the heaters 9 are provided in the flow paths 2 and 3. Each of the heaters 9 may be provided, and the air flowing in each of the flow paths 2 and 3 may have a temperature difference due to the ON / OFF switching of the heater 9 or the output change of the heater 9.
[0041]
【The invention's effect】
As described above, the hair dryer of the present invention can concentrate the air having the lower temperature and the air having the higher temperature on the desired part of the hair. It is possible to effectively prevent hair from being dried and fixed with air having a lower temperature and preventing excessive drying. Moreover, the inner nozzle is made of an inexpensive synthetic resin without using a member having a heat-resistant structure, so that the cost can be reduced, and a gap is formed between the downstream end of the inner cylinder and the upstream end of the inner nozzle. By forming the inner nozzle, it is possible to apply the lower temperature air flowing through the outer flow path to the upstream end portion of the inner nozzle, so that the inner nozzle is formed of an inexpensive synthetic resin having no heat resistance. Regardless, the inner nozzle can be prevented from being deformed or melted by the higher temperature air.
