Description

【０００１】
【発明の属する技術分野】
本発明は、スチーム式美容器に関し、詳しくは、ノズル外周面及びその近傍に生じた結露水をノズルから噴出することなく確実に給水タンクに戻す為の技術に関する。
【０００２】
【従来の技術】
スチーム式美容器とは、給水タンクやヒータにより成るスチーム発生装置で発生させたスチームをスチーム流路の先端に設けたノズルのスチーム噴出口から人体に向けて噴出させる為のものであり、肌の新陳代謝促進や毛髪に潤いを与える等といった美容効果を得ることのできるものであるが、ノズルの外周面やノズル近傍のスチーム流路内壁にはどうしても結露水（湯滴）が生じてしまい、これがスチーム圧によりノズルから噴出してしまうと使用者に火傷を負せる恐れがある。そこで、結露水の噴出を防ぐ為に特開２０００−０７００３９公報記載のスチーム式美容器のようにノズル自体に結露水を滴下して給水タンクに戻す為の機構を設けたものも提案されているのだが、上記したような滴下機構では、ノズル外周面の結露溜りが滴下機構を介して滴下するのに時間がかかり、滴下するまでの間に結露溜りが増加してしまう。結露溜りはその量が多い程にスチーム圧の変動等によって動きが不安定化するものであり、この為に或るタイミングで結露溜りがスチームとともにノズルを通って噴射されてしまうことがあった。
【０００３】
図７に示すように、従来はこれを解決する為に複数のひも状の金属をより込んで形成した復水部材３０をノズル１の下部に設置し、ノズル１の外周面に生じたノズル外周結露溜りＷ１を、復水部材３０の毛細管現象を利用してスチーム圧の変動等の影響を受けない復水部材３０の端部１６にまで強制的に引き込んでから滴下させる構成をとっていた。
【０００４】
しかし、この構成のものではスチーム量を大きくした場合に問題が生じる。つまり、スチーム流路内壁１７のノズル１近傍下側に形成した結露水生成蓄積部１８に蓄積されるノズル近傍結露溜りＷ２の生成量がスチーム量の増加に伴って増加し、加えて、ノズル近傍結露溜りＷ２を結露水生成蓄積部１８内に保持させる働きをするスチーム圧がスチーム量の増加に伴って増加することからノズル近傍結露溜りＷ２が給水タンク１３側に流れ出す為に必要となる溜り量も増加してしまい、これによりスチーム量が増大する程にノズル近傍結露溜りＷ２の溜り量が増加することとなる。
【０００５】
ノズル近傍結露溜りＷ２の溜り量が増加すると、復水部材３０はその一部がノズル近傍結露溜りＷ２に浸ってしまい、この為に毛細管現象が生じなくなってノズル外周結露溜りＷ１を復水部材３０の端部１６にまで引き込めなくなってしまうばかりか、復水部材４がノズル近傍結露溜りＷ２を水の表面張力によって保持してしまうといった現象が生じてしまう。このような現象が生じるとノズル近傍結露溜りＷ２はノズル１側に接近することとなるので、スチーム圧の変動等が生じるとノズル１からノズル近傍水溜りＷ２の一部が熱い湯滴となって噴出されてしまう可能性が高くなる。従って、使用スチームの量を規制する必要があった。
【０００６】
【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、ノズル外周結露溜りＷ２やノズル近傍結露溜りＷ１をノズル１から湯滴として噴出させることなく確実に給水タンク１３に戻すことのできる、ノズル１からの湯滴の噴出に対して安全性の高いスチーム式美容器を提供することを課題とするものである。
【０００７】
【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スチーム式美容器を、給水タンクと、給水タンク内の水を加熱するヒータと、ヒータの加熱により気化して成るスチームの移動するスチーム流路を有し、所定の長さを有する貫通した筒状であり且つ先端をスチーム噴出口としたノズルをスチーム流路内に位置させて、スチーム流路内を流れてきたスチームをノズルのスチーム噴出口から噴出させるスチーム式美容器において、結露水が蓄積される側のスチーム流路の内壁とノズルの外周面との間に、ノズルの中心軸に沿って棒状の復水部材を設けたことを特徴とするスチーム式美容器とする。
【０００８】
このようにすることで、復水部材と接触したノズル近傍結露溜りの不安定な動きを抑制するとともに、該ノズル近傍結露溜りを復水部材に伝わせて給水タンクに戻し、加えて、復水部材と接触したノズル外周結露溜りを復水部材に伝わせてノズル近傍結露溜りと結合させた後に給水タンクに戻すことができる。
【０００９】
また、ノズルの外周面と復水部材との間に隙間を設けることも好ましく、このようにすることで、ノズル外周結露溜りが復水部材を伝った後に再びノズル側に戻ることを防止することができる。
【００１０】
また、スチーム流路に結露水を給水タンクに戻す為の復水管路を設けるとともに、復水部材を復水管路に接触させることも好ましく、このようにすることで、復水部材を伝う結露水に毛細管現象を生じさせることができる。
【００１１】
また、復水部材を断面円形状に形成することも好ましく、このようにすることで、復水部材の表面積を小さく抑えて復水部材の外周面に生じる結露量を抑制することができ、加えて、表面張力によって復水部材が結露水を保持する力を抑制することもできる。
【００１２】
また、復水部材を円筒形状に形成することも好ましく、このようにすることで、ノズルと復水部材の下流側端部との間に生じた結露溜りを毛細管現象によって復水部材の円筒内部に伝わせることができる。
【００１３】
また、復水部材を高熱伝導性金属で形成することも好ましく、このようにすることで、復水部材の形状安定性や信頼性が経時的に確保されるとともに、復水部材の昇温速度が上昇するので復水部材の外周面に生じる結露量が抑制される。
【００１４】
また、復水部材を複数設けるとともに、それらを並列に配設することも好ましく、このようにすることで、ノズル近傍結露溜りを複数の結露溜りに分割して給水タンクに戻すことができ、分割された結露溜りを夫々強力に規制することができるとともに、夫々の結露溜りの溜り量を少なく抑えることができる。
【００１５】
また、ノズルの外周面を高撥水性に設けることも好ましく、このようにすることで、ノズルの外周面に生じた結露水を無数の小さな結露玉にし、ノズルから結露水への放熱量を減少させてノズルの昇温速度を上昇させることができ、これによりノズルの外周面における結露量を少なく抑えることができる。また、結露玉が結合して成るノズル外周結露溜りを溜り量の少ないうちに重力によって滴下させることができる。
【００１６】
【発明の実施の形態】
以下、本発明を添付図面に示す実施の形態に基づいて説明する。図３は本発明の実施の形態における一例の概略断面図であり、図示したように、スチーム式美容器１５は、給水タンク１３と、給水タンク１３内の水２０を加熱するヒータ１４と、ヒータ１４の加熱により気化して成るスチームの移動するスチーム流路３を有したものであり、スチーム流路３内の下流側には、所定の長さを有する貫通した筒状であり且つ先端をスチーム噴出口としたノズル１を位置させている。使用者はスチーム流路３を通ってノズル１のスチーム噴出口から噴出されたスチームを浴びることで肌の新陳代謝を促進させたり毛髪に潤いを与えたりといった美容効果を得る。
【００１７】
図１、図２には一例のノズル１近傍の構造が示してある。多孔質高熱伝導材１２（例えばＳＵＳ焼結体で形成）を内蔵したノズル１は、パッキン２により固定保持されている。ノズル１の上流側端面８周辺のスチーム流路内壁１７には、スチームの上流側を小径、下流側を大径として成る結露水生成蓄積部１８が設けられており、該結露水生成蓄積部１８とノズル１との間には棒状の復水部材４がノズル１の中心軸Ｃに沿って設けてある。
【００１８】
上記復水部材４は高熱伝導性金属で形成したものであり、固定部材６を介してその下流側端部をノズル１に固定させてあるとともに、上流側端部７を結露水生成蓄積部１８から上流側に延設されて成る復水管路９に接触させてある。ここでの復水管路９との接触は、復水部材４を伝う結露水に上流側端部７にて毛細管現象を生じさせる為のものであり、この毛細管現象によって、結露水の溜り量が少ないうちに復水部材４を伝うように結露水を引き込んで給水タンク１３に戻すことができる。また、固定部６としては、ばね性を有した金属等で形成するほうが保持力も得られて組立性も良くなるので好ましい。
【００１９】
結露水生成蓄積部１８にて蓄積されたノズル近傍結露溜りＷ２は、復水部材４との接触により、スチーム圧の変動等により生じる不安定な動きが水の表面張力の作用で抑制されるとともに、上流側端部７で生じる毛細管現象によって復水部材４を伝って復水管路９へと引き込まれ、溜り量が少ないうちに給水タンク１３に戻されることになるので、ノズル近傍結露溜りＷ２がノズル１に接近することが防止される。また、ノズル近傍結露溜りＷ２が給水タンク１３に戻るまでの復水経路は復水部材４を伝わることで固定した経路となり、この為に復水経路の固定されていないものが有することとなる不安定性要素は排除されているので、復水信頼性が向上する。
【００２０】
ノズル１の外周面の結露水が蓄積して生じたノズル外周結露溜りＷ１は、復水部材４を伝ってノズル近傍結露溜りＷ２と結合し、その後は一体となって上流側端部７で生じる毛細管現象によって復水部材４を伝って復水管路９へと引き込まれ、給水タンク１３に戻される。ここで、ノズル１と復水部材４との間には、ノズル外周結露溜りＷ１が復水部材４を伝った後に再びノズル１側に戻ってノズル１の下流側端面８と接触することのない程度の広さに隙間５を空けておくことで、復水信頼性が更に向上する。
【００２１】
上記したように、復水部材４を一つ設けることによってノズル近傍結露溜りＷ２とノズル外周結露溜りＷ１の両方を効率よく給水タンク１３に戻し、それらの結露溜りの一部が湯滴としてノズル１から噴き出されることを防止している。
【００２２】
また、復水部材４の形状は棒状であるとともに、図４に示すように断面円形状に形成されており、これにより復水部材４の表面積を小さくして復水部材４の外周面に生じる結露量を抑制している。更に、断面円形状にすることで、表面張力により復水部材４が結露水を保持する力が抑制されているので、ノズル外周結露溜りＷ１とノズル近傍結露溜りＷ２はスムーズに結合して給水タンク１３に戻されることとなる。従って、復水部材４を断面円形状に形成することで、ノズル近傍結露溜りＷ２の溜り量は更に少なく抑えられ、これによりノズル１からの湯滴の噴出しに対する安全性を更に向上させている。
【００２３】
また、復水部材４は高熱伝導性金属で形成されており、これによって復水部材４の昇温速度が速くなっているので、復水部材４の外周面に生じる結露量が少なく抑えられている。更に、金属で形成されていることで、形状安定性や信頼性が経時的に確保されるので復水信頼性も高い。
【００２４】
本例では、ノズル１の上流側端面８周辺のスチーム流路内壁１７に結露水生成蓄積部１８を形成しているが、このような結露水生成蓄積部１８を設けず、スチーム流路内壁１７をノズル１近辺においても略同径に形成したものであっても構わない。
【００２５】
図４には、本発明の実施の形態における他の例のノズル１周辺を示している。他の例のスチーム式美容器は、復水部材４の形状を貫通した円筒形状としたものであり、その他の構成は上記した一例のものと同様である。このようにすることで、ノズル外周結露溜りＷ１のなかでも特にノズル１と復水部材４の下流側端部との間に生じた結露溜りＷ３が毛細管現象によって復水部材４の円筒内部を伝わって、復水部材４の上流側端部と接触した復水管路９に導出されることとなる。従って、ノズル外周結露溜りＷ１の溜り量を低減させることができるので、ノズル１からの湯滴の噴出しに対する安全性が更に向上するものである。
【００２６】
図５には、本発明の実施の形態における更に他の例のノズル１周辺を示している。更に他の例のスチーム式美容器は、復水部材４として、円筒形状の左復水部材４ａ、中復水部材４ｂ、右復水部材４ｃを適当な隙間を空けて並列に配設したものであり、その他の構成は上記した一例のものと同様である。このようにすることで、ノズル近傍結露溜りＷ２は、図５（ｂ）中にて左復水部材４ａより左側に溜まって成る結露溜りＷ４と、左復水部材４ａと中復水部材４ｂの間に溜まって成る結露溜りＷ５と、中復水部材４ｂと右復水部材４ｃの間に溜まって成る結露溜りＷ６と、右復水部材４ｃの右側に溜まって成る結露溜りＷ７とに分割されたうえで夫々が復水経路を通って給水タンク１３に戻される。従って、結露溜りＷ４〜Ｗ７の夫々は溜り量が少なく抑えられるとともに動きを強力に規制されるので、ノズル１からの湯滴の噴出しに対する安全性が更に向上するものである。
【００２７】
図６には、本発明の実施の形態における別の例のノズル１を示している。別の例のノズル１は外周面を高撥水性としたものであり、その他の構成は上記した一例のものと同様である。本例では、高熱伝導性金属で形成されたノズル１の外周面に四弗化エチレン樹脂コート１１を処理することで上記高撥水性を実現させているが、ノズル１の外周面に酸化チタン処理を施したり、ノズル１自体を高撥水性の素材で形成したものであっても良い。
【００２８】
このような構成にすることで、ノズル１の外周面に生じた結露水は図示したように無数の小さな結露玉Ｗ８になるので、結露水とノズル１との接触面積が減少する。これによりノズル１から結露水への放熱量が減少してノズル１の昇温速度が速くなるので、ノズル１の外周面におけるスチームの飽和温度が高くなり、ノズル１の外周面での結露量が少なく抑えられる。また、上記した無数の結露玉Ｗ８が結合してノズル外周結露溜りＷ１を形成した場合にも、ノズル１の外周面における高撥水性によって溜り量の少ないうちに重力によってノズル外周結露溜りＷ１を滴下させることができる。従って、ノズル１の外周面を高撥水性に設けることで、ノズル１からの湯滴の噴出しに対する安全性が更に向上するものである。
【００２９】

BACKGROUND OF THE INVENTION
The present invention relates to a steam beauty machine, and more particularly to a technique for reliably returning condensed water generated on the outer peripheral surface of a nozzle and the vicinity thereof to a water supply tank without ejecting from the nozzle.
[0002]
[Prior art]
The steam beauty machine is for spraying the steam generated by a steam generator consisting of a water supply tank and heater from the steam outlet of the nozzle provided at the end of the steam channel toward the human body. Although it is possible to obtain cosmetic effects such as promoting metabolism and moisturizing hair, dew condensation (water droplets) is inevitably generated on the outer peripheral surface of the nozzle and the inner wall of the steam channel near the nozzle. If it is ejected from the nozzle due to pressure, there is a risk of burning the user. Therefore, in order to prevent the dew condensation water from being ejected, there is also proposed a mechanism provided with a mechanism for dripping dew condensation water onto the nozzle itself and returning it to the water supply tank, such as a steam beauty machine described in JP-A-2000-070039. However, in the dropping mechanism as described above, it takes time for the condensation on the outer peripheral surface of the nozzle to drop through the dropping mechanism, and the condensation is increased before the dropping. As the amount of the condensation pool increases, the movement becomes unstable due to the fluctuation of the steam pressure or the like. For this reason, the condensation pool may be sprayed through the nozzle together with the steam at a certain timing.
[0003]
As shown in FIG. 7, conventionally, in order to solve this problem, a condensing member 30 formed by inserting a plurality of string-like metals is installed in the lower part of the nozzle 1, and the outer periphery of the nozzle generated on the outer peripheral surface of the nozzle 1. The condensate reservoir W1 is forcibly drawn to the end portion 16 of the condensing member 30 that is not affected by fluctuations in steam pressure or the like using the capillary phenomenon of the condensing member 30 and then dropped.
[0004]
However, this configuration causes a problem when the steam amount is increased. That is, the generation amount of the near-condensation dew pool W2 accumulated in the dew condensation water generation accumulation section 18 formed on the lower side of the steam flow channel inner wall 17 near the nozzle 1 increases as the steam amount increases, and in addition, near the nozzle Since the steam pressure that works to hold the condensation pool W2 in the condensed water generation and accumulation unit 18 increases as the steam amount increases, the amount of pool necessary for the near-nozzle condensation pool W2 to flow toward the water supply tank 13 side. As a result, the amount of condensation in the near-nozzle condensation reservoir W2 increases as the amount of steam increases.
[0005]
When the amount of condensation in the nozzle near-condensation reservoir W2 increases, a part of the condensing member 30 is immersed in the nozzle near-condensation reservoir W2, so that the capillary phenomenon does not occur and the nozzle outer circumferential condensation reservoir W1 is removed from the condensing member 30. As a result, the condensing member 4 may not be able to be drawn into the end 16 of the nozzle, and the condensing member 4 may retain the condensation near the nozzle W2 due to the surface tension of water. When such a phenomenon occurs, the near-nozzle condensation pool W2 approaches the nozzle 1 side. Therefore, when the steam pressure fluctuates, a part of the near-nozzle pool W2 from the nozzle 1 becomes hot water droplets. The possibility of being ejected increases. Therefore, it was necessary to regulate the amount of steam used.
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of the above points, and the nozzle 1 that can reliably return the nozzle outer periphery condensation reservoir W2 and the nozzle vicinity condensation reservoir W1 to the water supply tank 13 without ejecting the nozzle 1 as hot water droplets. It is an object of the present invention to provide a steam-type beauty device that is highly safe against the squirting of hot water droplets.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, the steam beauty machine according to the present invention has a water supply tank, a heater for heating water in the water supply tank, and a steam flow path for moving steam that is vaporized by the heating of the heater. A nozzle having a predetermined length and having a penetrating cylinder and having a steam outlet at the tip is positioned in the steam channel, and the steam flowing in the steam channel is ejected from the steam outlet of the nozzle. In a steam beauty machine, a steam condensing member is provided along the central axis of the nozzle between the inner wall of the steam channel on the side where condensed water is accumulated and the outer peripheral surface of the nozzle. A beauty unit is used.
[0008]
In this way, the unstable movement of the condensation near the nozzle in contact with the condensing member is suppressed, and the condensation accumulation near the nozzle is transmitted to the condensing member and returned to the water supply tank. After the nozzle outer periphery condensation pool in contact with the member is transmitted to the condensing member and combined with the nozzle vicinity condensation pool, it can be returned to the water supply tank.
[0009]
In addition, it is also preferable to provide a gap between the outer peripheral surface of the nozzle and the condensing member. By doing so, it is possible to prevent the nozzle outer peripheral condensation from returning to the nozzle side again after passing through the condensing member. Can do.
[0010]
In addition, it is preferable to provide a condensate conduit for returning the condensed water to the water supply tank in the steam channel, and to bring the condensate member into contact with the condensate conduit. Can cause capillary action.
[0011]
In addition, it is also preferable to form the condensing member in a circular cross section, and in this way, the surface area of the condensing member can be suppressed to reduce the amount of condensation occurring on the outer peripheral surface of the condensing member. Thus, the force by which the condensing member holds the condensed water can be suppressed by the surface tension.
[0012]
It is also preferable that the condensing member is formed in a cylindrical shape, and in this way, the condensation pool formed between the nozzle and the downstream end of the condensing member is caused by capillarity inside the cylinder of the condensing member. Can be communicated to.
[0013]
It is also preferable to form the condensate member with a highly heat conductive metal, and in this way, the shape stability and reliability of the condensate member can be secured over time, and the rate of temperature rise of the condensate member As a result, the amount of condensation that occurs on the outer peripheral surface of the condensing member is suppressed.
[0014]
It is also preferable to provide a plurality of condensing members and arrange them in parallel. By doing so, the condensation reservoir near the nozzle can be divided into a plurality of condensation pools and returned to the water supply tank. It is possible to strongly regulate each of the condensation pools and to reduce the amount of each condensation pool.
[0015]
It is also preferable to provide the outer peripheral surface of the nozzle with high water repellency. By doing so, the condensed water generated on the outer peripheral surface of the nozzle is made into countless small dew condensation balls, and the amount of heat released from the nozzle to the condensed water is reduced. Thus, the temperature rising rate of the nozzle can be increased, and thereby the amount of dew condensation on the outer peripheral surface of the nozzle can be reduced. Moreover, the nozzle outer periphery dew condensation pool formed by combining dew condensation balls can be dropped by gravity while the amount of accumulation is small.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. FIG. 3 is a schematic cross-sectional view of an example in the embodiment of the present invention. As shown in the drawing, the steam beauty machine 15 includes a water supply tank 13, a heater 14 for heating water 20 in the water supply tank 13, and a heater. 14 is provided with a steam flow path 3 in which steam is formed by vaporization by heating, and the downstream side of the steam flow path 3 is a penetrating cylinder having a predetermined length and has a steam end. A nozzle 1 serving as a spout is located. The user obtains a cosmetic effect such as promoting the metabolism of the skin and moisturizing the hair by bathing the steam ejected from the steam outlet of the nozzle 1 through the steam flow path 3.
[0017]
1 and 2 show a structure in the vicinity of an example nozzle 1. A nozzle 1 incorporating a porous high thermal conductive material 12 (for example, formed of a SUS sintered body) is fixedly held by a packing 2. The steam flow channel inner wall 17 around the upstream end face 8 of the nozzle 1 is provided with a condensed water generation and accumulation unit 18 having a small diameter on the upstream side of the steam and a large diameter on the downstream side. A rod-shaped condensing member 4 is provided along the central axis C of the nozzle 1 between the nozzle 1 and the nozzle 1.
[0018]
The condensate member 4 is formed of a highly heat conductive metal, and its downstream end is fixed to the nozzle 1 via a fixing member 6, and the upstream end 7 is connected to the condensed water generation and accumulation unit 18. Is in contact with a condensate pipe 9 extending upstream. The contact with the condensate pipe line 9 here is for causing the condensed water passing through the condensing member 4 to generate a capillary phenomenon at the upstream end 7, and this capillary phenomenon causes the amount of condensed water to accumulate. The condensation water can be drawn back to the condensing member 4 and returned to the water supply tank 13 while the amount is small. Further, it is preferable that the fixing portion 6 is formed of a spring metal or the like because a holding force can be obtained and the assemblability can be improved.
[0019]
The near-nozzle condensation pool W <b> 2 accumulated in the condensed water generation and accumulation unit 18 is prevented from unstable movement caused by fluctuations in steam pressure or the like due to contact with the condensate member 4 due to the surface tension of water. Since the capillarity generated at the upstream end 7 is drawn into the condensate pipe 9 through the condensing member 4 and returned to the water supply tank 13 while the amount of accumulation is small, the condensation near the nozzle W2 Access to the nozzle 1 is prevented. Further, the condensate path until the condensate reservoir W2 near the nozzle returns to the water supply tank 13 becomes a fixed path by being transmitted through the condensing member 4, and for this reason, there is an anxiety that the condensate path is not fixed. Since the qualitative element is excluded, the condensate reliability is improved.
[0020]
Nozzle outer periphery dew pool W1 generated by the accumulation of dew condensation water on the outer peripheral surface of the nozzle 1 is coupled to the near nozzle dew pool W2 through the condensing member 4 and then integrally formed at the upstream end 7. It is drawn into the condensate conduit 9 through the condensing member 4 by capillary action and returned to the water supply tank 13. Here, between the nozzle 1 and the condensing member 4, the nozzle outer circumferential condensation pool W <b> 1 does not return to the nozzle 1 side after passing through the condensing member 4 and comes into contact with the downstream end face 8 of the nozzle 1. The condensate reliability is further improved by leaving the gap 5 to be as wide as possible.
[0021]
As described above, by providing one condensing member 4, both the nozzle near-condensation reservoir W <b> 2 and the nozzle outer-perimeter condensation reservoir W <b> 1 are efficiently returned to the water supply tank 13, and a part of these condensation reservoirs serve as hot water droplets in the nozzle 1. It is prevented from being ejected from.
[0022]
Further, the condensing member 4 has a rod shape and is formed in a circular cross section as shown in FIG. 4, thereby reducing the surface area of the condensing member 4 and generating it on the outer peripheral surface of the condensing member 4. Condensation is suppressed. Furthermore, since the condensing member 4 is restrained from holding the condensed water by the surface tension due to the circular cross-section, the nozzle outer peripheral condensation reservoir W1 and the nozzle near-condensation reservoir W2 are smoothly connected to each other to form a water supply tank. 13 will be returned. Therefore, by forming the condensing member 4 in a circular cross-section, the amount of condensation in the vicinity of the nozzle condensation W2 can be further reduced, thereby further improving the safety against the ejection of hot water droplets from the nozzle 1. .
[0023]
In addition, the condensing member 4 is formed of a highly heat conductive metal, and thereby the condensing member 4 is heated at a higher rate, so that the amount of dew condensation that occurs on the outer peripheral surface of the condensing member 4 is reduced. Yes. Furthermore, since it is formed of metal, shape stability and reliability are secured over time, so that condensate reliability is high.
[0024]
In this example, the condensed water generation / accumulation part 18 is formed on the steam flow path inner wall 17 around the upstream end face 8 of the nozzle 1. However, the condensed flow generation / accumulation part 18 is not provided, and the steam flow path inner wall 17 is not provided. May be formed to have substantially the same diameter in the vicinity of the nozzle 1.
[0025]
FIG. 4 shows the periphery of the nozzle 1 of another example in the embodiment of the present invention. The steam beauty machine of another example is a cylindrical shape penetrating the shape of the condensing member 4, and the other configuration is the same as that of the above example. By doing in this way, the condensation pool W3 generated especially between the nozzle 1 and the downstream end of the condensing member 4 among the nozzle outer circumferential condensation pool W1 is transmitted through the inside of the condensing member 4 by capillarity. Thus, the water is led out to the condensate conduit 9 in contact with the upstream end of the condensate member 4. Accordingly, since the amount of accumulation in the nozzle outer peripheral condensation reservoir W1 can be reduced, the safety against ejection of hot water droplets from the nozzle 1 is further improved.
[0026]
FIG. 5 shows the periphery of the nozzle 1 of still another example in the embodiment of the present invention. Still another example of the steam beauty machine is a condensing member 4 in which a cylindrical left condensing member 4a, a middle condensing member 4b, and a right condensing member 4c are arranged in parallel with an appropriate gap therebetween. Other configurations are the same as those in the above-described example. By doing in this way, the condensate reservoir W2 near the nozzle is formed by the condensation reservoir W4 that is accumulated on the left side of the left condensing member 4a in FIG. 5B, the left condensing member 4a, and the middle condensing member 4b. It is divided into a condensation reservoir W5 that accumulates in the middle, a condensation reservoir W6 that accumulates between the middle condensate member 4b and the right condensate member 4c, and a condensation reservoir W7 that accumulates on the right side of the right condensate member 4c. In addition, each is returned to the water supply tank 13 through the condensate path. Accordingly, each of the dew pools W4 to W7 is restrained in the amount of accumulation and is strongly restricted in movement, so that the safety against the ejection of hot water droplets from the nozzle 1 is further improved.
[0027]
In FIG. 6, the nozzle 1 of another example in embodiment of this invention is shown. Another example of the nozzle 1 has an outer peripheral surface with high water repellency, and the other configuration is the same as that of the above example. In this example, the high water repellency is realized by treating the outer peripheral surface of the nozzle 1 made of a highly heat conductive metal with the ethylene tetrafluoride resin coat 11, but the outer peripheral surface of the nozzle 1 is treated with titanium oxide. The nozzle 1 itself may be formed of a highly water-repellent material.
[0028]
With this configuration, the dew condensation water generated on the outer peripheral surface of the nozzle 1 becomes an infinite number of small dew condensation balls W8 as shown in the figure, so that the contact area between the dew condensation water and the nozzle 1 is reduced. As a result, the amount of heat released from the nozzle 1 to the condensed water is reduced and the heating rate of the nozzle 1 is increased, so that the steam saturation temperature on the outer peripheral surface of the nozzle 1 is increased, and the dew amount on the outer peripheral surface of the nozzle 1 is increased. It can be reduced. In addition, even when the infinite number of dew condensation balls W8 described above are combined to form the nozzle outer periphery condensation reservoir W1, the nozzle outer periphery condensation reservoir W1 is dropped by gravity while the accumulation amount is small due to the high water repellency on the outer peripheral surface of the nozzle 1. Can be made. Therefore, by providing the outer peripheral surface of the nozzle 1 with high water repellency, the safety against the ejection of hot water droplets from the nozzle 1 is further improved.
