Description

本発明は、水を加熱して発生させたスチームを肌に向けて噴射するスチーム式美容器等で用いられるスチームノズルに関するものである。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steam nozzle used in a steam beauty device or the like that jets steam generated by heating water toward the skin.

従来、この種のスチームノズルとしては、蒸気発生装置で発生させた蒸気を、ノズルから被施術者の顔に吹き付けるスチーム式美容器等で用いられるものが知られている（例えば、特許文献１参照。）。このようなスチームノズルでは、前記ノズルで蒸気が結露して高温の水滴になり、この水滴が蒸気流と共に前記ノズルから噴出して被施術者の顔にかかる虞があるので、前記ノズルのスチーム通路の出口側に吸水体を設けると共に、前記スチーム通路に水滴を前記給水体に導くための導水体を設け、前記吸水体によって水滴を吸水することで、水滴が前記ノズルから噴出しないように構成されている。 Conventionally, as this type of steam nozzle, there has been known one used in a steam beauty device or the like in which steam generated by a steam generator is sprayed from the nozzle onto the face of the subject (see, for example, Patent Document 1). .). In such a steam nozzle , the steam condenses on the nozzle and turns into high-temperature water droplets, and the water droplets are ejected from the nozzle together with the steam flow, and there is a risk that the water droplets may splash on the subject's face. A water absorbing body is provided on the outlet side of the steam passage, and a water conducting body is provided in the steam passage for guiding water droplets to the water supply body. ing.

しかしながら、このようなスチームノズルにおいては、前記吸水体に吸収可能な結露水の量に対して、噴出されるスチーム流に押し出される高温の結露水の量が多くなると、前記吸水体に結露水を吸収しきれず、この吸水体を飛び超えて熱い水滴が噴出される虞があった。 However, in such a steam nozzle , if the amount of high-temperature condensed water pushed out by the ejected steam flow is greater than the amount of condensed water that can be absorbed by the water absorber, the water absorber will absorb the condensed water. There is a risk that hot water droplets will be jetted out over the water absorber because the water cannot be completely absorbed.

本発明は以上の問題点を解決し、結露水を確実に吸水体に吸収させることができる安全なスチームノズルを提供することを目的とする。 SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide a safe steam nozzle capable of reliably absorbing dew condensation water into a water absorber.

本発明の請求項１に記載のスチームノズルは、ノズル本体と、このノズル本体におけるスチーム通路の最狭部の出口側に設けられた吸水体と、前記スチーム通路の最狭部から前記吸水体へ結露水を導く導水部が設けられた導水体とを有し、この導水体が、前記最狭部の内径よりも細い金属線を折り曲げて形成され、前記導水部が、第一導水部と第二導水部を有し、前記第一導水部が、前記スチーム通路の内周面における使用時に下側となる部分に沿って前記スチーム通路と平行に配され、前記第二導水部が、前記スチーム通路の最狭部の出口から使用時に下側となる方向に延びて配されるスチームノズルにおいて、前記最狭部の内周面における使用時に下側となる部分に隙間部が設けられ、この隙間部の近傍に前記導水体の導水部が設けられるものである。 A steam nozzle according to claim 1 of the present invention comprises a nozzle body, a water absorber provided on the outlet side of the narrowest part of the steam passage in the nozzle body, and a water absorber from the narrowest part of the steam passage to the water absorber. a water conducting body provided with a water conducting part for guiding condensed water, the water conducting body being formed by bending a metal wire thinner than the inner diameter of the narrowest part, the water conducting part comprising a first water conducting part and a second water conducting part; It has two water conveying portions, wherein the first water conveying portion is arranged parallel to the steam passage along a portion of the inner peripheral surface of the steam passage that is the lower side during use, and the second water conveying portion is arranged along the steam passage. In a steam nozzle extending from an outlet at the narrowest part of a passage in a direction downward during use, a clearance is provided in a portion of the inner peripheral surface of the narrowest part that becomes downward during use. A water conveying portion of the water conveying body is provided in the vicinity of the portion.

また、本発明の請求項２に記載のスチームノズルは、請求項１において、前記スチーム通路の最狭部が筒状のスリーブで構成されると共に、このスリーブに前記隙間部が形成されるものである。
According to claim 2 of the present invention, there is provided a steam nozzle according to claim 1, wherein the narrowest portion of the steam passage is composed of a tubular sleeve, and the sleeve is formed with the clearance. is.

また、本発明の請求項３に記載のスチームノズルは、請求項２において、前記隙間部がスリット形状とされるものである。 According to claim 3 of the present invention, there is provided a steam nozzle according to claim 2, wherein the clearance is slit-shaped.

また、本発明の請求項４に記載のスチームノズルは、請求項２において、前記隙間部が凹形状とされるものである。 According to claim 4 of the present invention, there is provided a steam nozzle according to claim 2, wherein the gap is recessed.

更に、本発明の請求項５に記載のスチームノズルは、請求項１から４のいずれか一項において、前記隙間部が毛細管現象を生じる寸法とされるものである。 Further, according to claim 5 of the present invention, in the steam nozzle according to any one of claims 1 to 4, the gap has a dimension that causes capillary action.

本発明の請求項１に記載のスチームノズルは、以上のように構成することにより、前記スチーム通路の最狭部に発生した結露水が、前記最狭部の内壁に沿って流下し、前記隙間部に導かれて前記吸水体に至り、この吸水体で吸収されるので、結露水を確実に前記吸水体まで導いて、熱い結露水が勢いよく噴出して顔等にかかることを抑制することができる。また、前記隙間部によって、前記吸水体に導かれる結露水の量が多くなるので、結露水の発生が多くなっても、確実に前記吸水体に結露水を吸水させることができる。更に、前記隙間部においても結露水を保持することができるので、熱い結露水が噴出することをより確実に抑制することができる。 The steam nozzle according to claim 1 of the present invention is configured as described above, so that dew condensation water generated at the narrowest part of the steam passage flows down along the inner wall of the narrowest part, Since the condensed water is led to the water absorbing body and is absorbed by the water absorbing body, the hot condensed water is surely guided to the water absorbing body, and the hot condensed water is prevented from spouting vigorously and splashing on the face or the like. can be done. In addition, since the amount of condensed water led to the water absorber increases due to the gap, even if the amount of condensed water increases, the water absorber can reliably absorb the condensed water. Furthermore, since the condensed water can be retained even in the gap, it is possible to more reliably prevent the hot condensed water from blowing out.

なお、前記スチーム通路の最狭部が筒状のスリーブで構成されると共に、このスリーブに前記隙間部が形成されることで、間隙寸法の小さな隙間部を容易に構成することができる。
By forming the narrowest part of the steam passage with a cylindrical sleeve and forming the clearance in the sleeve, it is possible to easily form a clearance with a small clearance dimension.

また、前記隙間部がスリット形状とされることで、前記最狭部の内壁に沿って前記隙間部に導かれる結露水を、効率的に前記導水体の導水部に沿わせることができるので、結露水を確実に前記吸水体まで導くことができる。 In addition, since the gap has a slit shape, the condensed water guided to the gap along the inner wall of the narrowest portion can be efficiently directed along the water conveying portion of the water conduit. Condensed water can be reliably guided to the water absorber.

また、前記隙間部が凹形状とされることで、前記最狭部の強度を保ちつつ、結露水を前記導水体の導水部から前記吸水体に導くことができる。 In addition, by forming the gap portion into a concave shape, the condensed water can be guided from the water conducting portion of the water conducting body to the water absorbing body while maintaining the strength of the narrowest portion.

更に、前記隙間部が毛細管現象を生じる寸法とされることで、前記隙間部に導かれた結露水を確実に前記吸水体まで導くことができる。 Furthermore, by setting the gap to a dimension that causes capillary action, the condensed water guided to the gap can be reliably guided to the water absorber.

以下、本発明の第一の実施形態について、図１乃至図３に基づいて説明する。なお、本実施形態において、図２（ａ）の左側を前、右側を後と規定する。１は本発明のスチームノズルである。このスチームノズル１は、ノズル本体２と、スリーブ３と、導水体４と、吸水体５と、スチームパイプ６とを有する。なお、このスチームパイプ６は、図示しないスチーム発生手段に接続される。そして、前記スチーム発生手段が発生させたスチームが、前記スチームノズル１内に設けられたスチーム通路Ｐを通過して噴出される。 A first embodiment of the present invention will be described below with reference to FIGS. 1 to 3. FIG. In this embodiment, the left side of FIG. 2A is defined as front, and the right side is defined as rear. 1 is the steam nozzle of the present invention. This steam nozzle 1 has a nozzle body 2 , a sleeve 3 , a water conductor 4 , a water absorber 5 and a steam pipe 6 . The steam pipe 6 is connected to steam generating means (not shown). The steam generated by the steam generating means passes through the steam passage P provided in the steam nozzle 1 and is jetted out.

前記ノズル本体２は、合成樹脂によって形成される。そして、前記ノズル本体２は、後側の径小部７と、前側の径大部８と、これら径小部７と径大部８との間に設けられる段差部９とを有する。前記径小部７は、軸方向両端が開放した短円筒状に形成される。そして、前記径小部７の内面には、フランジ状の位置決めリブ１０が形成される。なお、この位置決めリブ１０の下部には、隙間部としてのスリット状の切欠部１１が形成される。本発明において、スリット状とは、完全に切り離された状態を示す。即ち、前記位置決めリブ１０は、前記切欠部１１によって軸回り方向に切り離される。更に、前記位置決めリブ１０の中央部には、スチームの通孔１２が形成される。即ち、前記切欠部１１と通孔１２は繋がる。また、前記径大部８は、前記径小部７よりも径大で且つ軸方向両端が開放した短円筒状に形成される。そして、前記径大部８の前端が噴出口１３となる。更に、前記段差部９は、前記径小部７の前端から外側に、且つ前記径大部８の後端から内側に、フランジ状に突出して形成される。 The nozzle body 2 is made of synthetic resin. The nozzle body 2 has a small diameter portion 7 on the rear side, a large diameter portion 8 on the front side, and a stepped portion 9 provided between the small diameter portion 7 and the large diameter portion 8 . The small diameter portion 7 is formed in a short cylindrical shape with both ends in the axial direction open. A flange-like positioning rib 10 is formed on the inner surface of the small diameter portion 7 . A slit-shaped notch 11 is formed as a gap in the lower portion of the positioning rib 10 . In the present invention, the term "slit-like" indicates a completely separated state. That is, the positioning rib 10 is cut off in the axial direction by the notch 11 . Furthermore, a steam passage hole 12 is formed in the central portion of the positioning rib 10 . That is, the notch 11 and the through hole 12 are connected. The large-diameter portion 8 is larger in diameter than the small-diameter portion 7 and is formed in a short cylindrical shape with both ends in the axial direction open. A front end of the large-diameter portion 8 serves as a jet port 13 . Further, the stepped portion 9 is formed to protrude outwardly from the front end of the small diameter portion 7 and inwardly from the rear end of the large diameter portion 8 in a flange shape.

前記スリーブ３は、真鍮等の金属により、軸方向両端が開放した略円筒状に形成されると共に、前記径小部７に挿入される。そして、前記スリーブ３の後端は、前記位置決めリブ１０に当接して位置決めされる。この状態で、前記スリーブ３の前端は、前記径小部７の前端とほぼ同じ位置にある。また、前記スリーブ３の下部には、隙間部としてのスリット状の切欠部１４が形成される。即ち、前記スリーブ３は、スリット状の切欠部１１によって軸回り方向に切り離され、図２（ｂ）に示すように、軸直断面形状がＣ字状となる。更に、前記スリーブ３の中央部には、軸方向に通孔１５が形成される。即ち、前記切欠部１４と通孔１５は繋がる。なお、前記位置決めリブ１０の通孔１２と前記スリーブ３の通孔１５は略同径である。従って、前記通孔１２と通孔１５の位置が、スチーム通路Ｐの最狭部１６となる。また、前記位置決めリブ１０の切欠部１１と前記スリーブ３の切欠部１４は連通する。 The sleeve 3 is made of metal such as brass and is formed into a substantially cylindrical shape with both axial ends open, and is inserted into the small diameter portion 7 . The rear end of the sleeve 3 abuts against the positioning rib 10 and is positioned. In this state, the front end of the sleeve 3 is at approximately the same position as the front end of the small diameter portion 7 . A slit-shaped notch 14 is formed as a gap in the lower portion of the sleeve 3 . That is, the sleeve 3 is separated in the axial direction by the slit-shaped notch 11, and as shown in FIG. Furthermore, a through hole 15 is formed in the central portion of the sleeve 3 in the axial direction. That is, the notch 14 and the through hole 15 are connected. The through hole 12 of the positioning rib 10 and the through hole 15 of the sleeve 3 have substantially the same diameter. Therefore, the position of the through hole 12 and the through hole 15 is the narrowest portion 16 of the steam passage P. Also, the notch portion 11 of the positioning rib 10 and the notch portion 14 of the sleeve 3 communicate with each other.

前記導水体４は、前記スチーム通路Ｐを通るように取り付けられる。前記導水体４は、前記スリーブ３の通孔１５、即ち前記最狭部１６の内径よりも細い一本の金属線を折り曲げて形成される。このため、前記導水体４は容易に且つ安価に形成される。そして、前記導水体４は、図２（ａ）及び図３に示すように、前記スチーム通路Ｐの軸方向とほぼ平行となる直線状の第一導水部１７と、この第一導水部１７の出口側に軸直方向で且つ下方に折り曲げられて形成される直線状の第二導水部１８と、前記第一導水部１７の入口側に下方に折り曲げられて形成される直線状の戻水部１９と、前記第二導水部１８の先端部から前記スチーム通路Ｐの軸回りに延びる環状部２０とを有して構成される。そして、前記第一導水部１７は、前記切欠部１１，１４と平行に配される。また、前記第二導水部１８は、前記切欠部１４と平行に配される。 The water conductor 4 is attached so as to pass through the steam passage P. As shown in FIG. The water conductor 4 is formed by bending a single metal wire thinner than the inner diameter of the through hole 15 of the sleeve 3 , ie, the narrowest portion 16 . Therefore, the water conductor 4 can be easily and inexpensively formed. As shown in FIGS. 2(a) and 3, the water conduit 4 includes a linear first water conduit 17 substantially parallel to the axial direction of the steam passage P, and the first water conduit 17. A linear second water conveying portion 18 formed by bending downward in the axial direction on the outlet side, and a linear water returning portion formed by bending downward on the inlet side of the first water conveying portion 17. 19 and an annular portion 20 extending around the axis of the steam passage P from the tip of the second water conveying portion 18 . The first water guide portion 17 is arranged parallel to the notch portions 11 and 14 . Also, the second water guide portion 18 is arranged parallel to the notch portion 14 .

前記吸水体５は、フェルト等の吸水性材料で環状に形成されると共に、径大部８の内側で且つ前記段差部９の前側に挿入される。なお、この吸水体５の外径は、前記径大部８の内径とほぼ等しく形成される。また、前記吸水体５の内径は、前記径小部７の内径よりも大きく形成される。 The water absorber 5 is made of a water absorbent material such as felt and is formed in an annular shape, and is inserted inside the large-diameter portion 8 and in front of the stepped portion 9 . The outer diameter of the water absorber 5 is formed substantially equal to the inner diameter of the large diameter portion 8 . Moreover, the inner diameter of the water absorber 5 is formed to be larger than the inner diameter of the small diameter portion 7 .

前記スチームパイプ６は、シリコンゴム等、耐熱性及び可撓性を有する材質で構成される。このように、前記スチームパイプ６が耐熱性及び可撓性を有することで、高温のスチームを通すことが可能となり、また、前記スチームノズル１の向きを変えることができる。 The steam pipe 6 is made of a heat-resistant and flexible material such as silicone rubber. Since the steam pipe 6 has heat resistance and flexibility in this way, it is possible to pass high-temperature steam and change the orientation of the steam nozzle 1 .

次に、本実施形態の作用について説明する。まず、図示しないスチーム発生手段によってスチームを発生させると共に、発生したスチームを前記スチーム通路Ｐに送る。前記スチームは、前記スチームパイプ６からノズル本体２の通孔１２、スリーブ３の通孔１５を通って、前記スチームノズル１の噴出口１３から前記スチーム通路Ｐの中心軸線方向にスチームが噴出する。 Next, the operation of this embodiment will be described. First, steam is generated by a steam generating means (not shown), and the generated steam is sent to the steam passage P. As shown in FIG. The steam flows from the steam pipe 6 through the through hole 12 of the nozzle body 2 and through the through hole 15 of the sleeve 3, and is jetted out from the jet port 13 of the steam nozzle 1 in the central axis direction of the steam passage P.

前記スチームノズル１からスチームを噴射させ続けると、前記スチーム通路Ｐ内でスチームが凝縮し、高温で液体状の結露水が発生する。そして、この結露水の水滴が多数結合すると、この水滴が大きく成長し、スチーム流に押し出される虞がある。しかしながら、前記導水体４の第一導水部１７が、最狭部１６である前記位置決めリブ１０の通孔１２の内周面における下側、及び最狭部１６である前記スリーブ３の通孔１５の内周面における下側に近接しているので、重力によって前記通孔１２，１５の内周面に沿って流下した水滴は、毛細管現象によって、前記切欠部１１，１４の縁と前記第一導水部１７とで形成された微小な隙間に広い範囲で吸引保持される。また、結露水は、毛細管現象によって、前記位置決めリブ１０の切欠部１１及び前記スリーブ３の切欠部１４にも吸引保持される。この状態では、結露水は、前記スチーム通路Ｐの流通面積（前記通孔１２，１５の流通面積）を殆ど狭めないので、スチーム流が結露水を勢いよく押し出すことがない。そして、更に結露水が流下して前記隙間に結露水が溜まると、この溜まった結露水がスチーム流に押されて、前記隙間から押し出される。この押し出された結露水は、前記第一導水部１７に接しているので、この第一導水部１７に沿って前記スリーブ３（最狭部１６）の前端部から外側に移動する。そして、前記第一導水部１７に沿って外側に移動した結露水は、前記第一導水部１７と一体に設けられた前記第二導水部１８に沿って、下方に、即ち前記吸水体５に向かって流れる。更に、この第二導水部１８に沿って流れた結露水は、前記第二導水部１８と接する前記吸水体５に吸収される。このように、結露水が前記導水体４に沿って前記吸水体５に送られるので、熱い結露水が前記スチームノズル１の噴出口１３から勢いよく噴出して顔等にかかることを抑制することができる。 If the steam is continuously jetted from the steam nozzle 1, the steam condenses in the steam passage P, and high-temperature liquid condensed water is generated. When a large number of water droplets of the condensed water combine, the water droplets grow large and may be pushed out by the steam flow. However, the first water conveying portion 17 of the water conductor 4 is located below the inner peripheral surface of the through hole 12 of the positioning rib 10 which is the narrowest portion 16 and the through hole 15 of the sleeve 3 which is the narrowest portion 16. , the water droplets that have flowed down along the inner peripheral surfaces of the through holes 12 and 15 due to gravity flow along the edges of the cutouts 11 and 14 and the first It is sucked and held over a wide range in a minute gap formed by the water guide portion 17 . Also, the condensed water is sucked and held in the notch 11 of the positioning rib 10 and the notch 14 of the sleeve 3 by capillary action. In this state, the condensed water hardly narrows the circulation area of the steam passage P (the circulation area of the through holes 12 and 15), so the steam flow does not force the condensed water out. When the condensed water further flows down and accumulates in the gap, the accumulated condensed water is pushed out from the gap by the steam flow. The extruded condensed water is in contact with the first water conveying portion 17 , and therefore moves outward from the front end portion of the sleeve 3 (narrowest portion 16 ) along the first water conveying portion 17 . Then, the condensed water that has moved outward along the first water conveying portion 17 travels downward along the second water conveying portion 18 provided integrally with the first water conveying portion 17, that is, to the water absorber 5. flow towards. Furthermore, the condensed water that has flowed along the second water guide portion 18 is absorbed by the water absorber 5 that is in contact with the second water guide portion 18 . Since the condensed water is sent to the water absorber 5 along the water conductor 4 in this way, hot condensed water is prevented from spouting vigorously from the spout 13 of the steam nozzle 1 and splashing on the face or the like. can be done.

なお、前記結露水は、前記切欠部１１，１４を経由して前記吸水体５に送られるようにすることもできる。この場合、前記切欠部１１，１４の縁と前記第一導水部１７との間の微少な隙間だけでなく、前記切欠部１１，１４経由でも結露水を前記吸水体５に送ることができるので、効率よく結露水を前記吸水体５に吸収させることができる。この結果、結露水をより確実に前記スチームノズル１の噴出口１３から噴出させないようにすることができる。 The condensed water can also be sent to the water absorber 5 via the cutouts 11 and 14 . In this case, the condensed water can be sent to the water absorber 5 not only through the minute gaps between the edges of the cutouts 11 and 14 and the first water conveying portion 17 but also through the cutouts 11 and 14. , the water absorber 5 can efficiently absorb the condensed water. As a result, it is possible to prevent the condensed water from being ejected from the ejection port 13 of the steam nozzle 1 more reliably.

また、前記吸水体５が吸水能力の限界を超えた場合、吸収しきれなかった結露水が水滴となって前記噴出口１３から噴出する虞があった。しかしながら、前述したように、前記切欠部１１，１４に結露水が吸引保持されるので、前記吸水体５が吸水能力の限界を超えた場合、吸収しきれなかった結露水が前記切欠部１１，１４に貯められることになる。そして、この切欠部１１，１４に保持可能な水量を超えると、結露水は、前記切欠部１１を通って前記スチームパイプ６に戻される。なお、前記スチーム通路Ｐは、前記位置決めリブ１０及びスリーブ３の位置において最狭部１６となる、即ちこの最狭部１６において段差状に流通面積が絞られるので、この最狭部１６よりも上流側の水滴が前記最狭部１６を通って前記噴出口１３から噴出することはない。更に、前記切欠部１１，１４の縁と第一導水部１７との間の微少な隙間に溜まった結露水は、前記第一導水部１７及び戻水部１９に沿って、前記スチームパイプ６内に戻される。この際、前述したように、前記戻水部１９が下方に曲げられるので、重力によって前記結露水の水滴を確実に前記スチームパイプ６内に戻すことができる。 In addition, when the water absorbing body 5 exceeds the limit of its water absorption capacity, there is a possibility that the condensed water that cannot be absorbed becomes water droplets and is ejected from the ejection port 13 . However, as described above, since the condensed water is sucked and held in the cutouts 11 and 14, when the water absorber 5 exceeds the limit of the water absorption capacity, the condensed water that could not be absorbed It will be saved at 14. When the amount of water that can be held in the cutouts 11 and 14 is exceeded, the condensed water is returned to the steam pipe 6 through the cutouts 11 . The steam passage P becomes the narrowest portion 16 at the position of the positioning rib 10 and the sleeve 3 . Water droplets on the side do not pass through the narrowest portion 16 and jet from the jet port 13 . Furthermore, the condensed water accumulated in the minute gaps between the edges of the cutouts 11 and 14 and the first water conveying portion 17 flows along the first water conveying portion 17 and the water returning portion 19 into the steam pipe 6. returned to At this time, as described above, since the water return portion 19 is bent downward, the water droplets of the condensed water can be surely returned into the steam pipe 6 by gravity.

前記スリーブ２３は、真鍮等の金属により、軸方向両端が開放した略円筒状に形成されると共に、前記径小部２７に挿入される。そして、前記スリーブ２３の後端は、前記位置決めリブ３０に当接して位置決めされる。この状態で、前記スリーブ２３の前端は、前記径小部２７の前端とほぼ同じ位置にある。また、前記スリーブ２３の内面下部には、隙間部としての凹状の溝部３４が形成される。この溝部３４は、前記スリーブ２３の軸方向と平行に形成される。また、前記スリーブ２３は、第一の実施形態とは異なり、前記溝部３４の外周側において一部が繋がる。更に、前記スリーブ２３の中央部には、軸方向に通孔３５が形成される。即ち、前記溝部３４は、前記通孔３５と繋がる。なお、前記位置決めリブ３０の通孔３２と前記スリーブ２３の通孔３５は略同径である。従って、前記通孔３２と通孔３５の位置が、スチーム通路Ｐ’の最狭部３６となる。また、前記位置決めリブ３０の溝部３１と前記スリーブ３２の溝部３４は連通する。 The sleeve 23 is made of metal such as brass and is formed into a substantially cylindrical shape with both axial ends open, and is inserted into the small diameter portion 27 . The rear end of the sleeve 23 is positioned by contacting the positioning rib 30 . In this state, the front end of the sleeve 23 is at approximately the same position as the front end of the small diameter portion 27 . Further, a recessed groove portion 34 is formed as a clearance portion in the lower inner surface of the sleeve 23 . This groove portion 34 is formed parallel to the axial direction of the sleeve 23 . Also, unlike the first embodiment, the sleeve 23 is partially connected to the groove portion 34 on the outer peripheral side. Furthermore, a through hole 35 is formed in the central portion of the sleeve 23 in the axial direction. That is, the groove portion 34 is connected to the through hole 35 . The through hole 32 of the positioning rib 30 and the through hole 35 of the sleeve 23 have substantially the same diameter. Therefore, the position of the through hole 32 and the through hole 35 is the narrowest portion 36 of the steam passage P'. Further, the groove portion 31 of the positioning rib 30 and the groove portion 34 of the sleeve 32 communicate with each other.

前記導水体４は、前記スチーム通路Ｐ’を通るように取り付けられる。前記導水体４は、前記スリーブ２３の通孔３５、即ち前記最狭部３６の内径よりも細い一本の金属線を折り曲げて形成される。このため、前記導水体４は容易に且つ安価に形成される。そして、前記導水体４は、前記スチーム通路Ｐ’の軸方向とほぼ平行となる直線状の第一導水部１７と、この第一導水部１７の出口側に軸直方向で且つ下方に折り曲げられて形成される直線状の第二導水部１８と、前記第一導水部１７の入口側に下方に折り曲げられて形成される直線状の戻水部１９と、前記第二導水部１８の先端部から前記スチーム通路Ｐの軸回りに延びる環状部２０とを有して構成される。そして、前記第一導水部１７は、前記溝部３１，３４と平行に配される。また、前記第二導水部１８は、前記溝部３４と平行に配される。 The water conductor 4 is mounted so as to pass through the steam passage P'. The water conductor 4 is formed by bending a single metal wire thinner than the inner diameter of the through hole 35 of the sleeve 23 , ie, the narrowest portion 36 . Therefore, the water conductor 4 can be easily and inexpensively formed. The water guide body 4 includes a straight first water guide portion 17 that is substantially parallel to the axial direction of the steam passage P′, and an outlet side of the first water guide portion 17 that is bent downward in the direction perpendicular to the axis. a straight second water conveying portion 18 that is formed by a straight water conveying portion 18, a straight water returning portion 19 that is formed by bending downward toward the inlet side of the first water conveying portion 17, and a tip portion of the second water conveying portion 18 and an annular portion 20 extending around the axis of the steam passage P from the . The first water guide portion 17 is arranged parallel to the grooves 31 and 34 . Also, the second water guide portion 18 is arranged parallel to the groove portion 34 .

The outer diameter of the water absorber 5 is formed substantially equal to the inner diameter of the large diameter portion 28 . Moreover, the inner diameter of the water absorber 5 is formed to be larger than the inner diameter of the small diameter portion 27 .

前記スチームパイプ６は、シリコンゴム等、耐熱性及び可撓性を有する材質で構成される。このように、前記スチームパイプ６が耐熱性及び可撓性を有することで、高温のスチームを通すことが可能となり、また、前記スチームノズル２１の向きを変えることができる。 The steam pipe 6 is made of a heat-resistant and flexible material such as silicone rubber. Since the steam pipe 6 has heat resistance and flexibility in this way, it is possible to pass high-temperature steam and change the direction of the steam nozzle 21 .

次に、本実施形態の作用について説明する。まず、図示しないスチーム発生手段によってスチームを発生させると共に、発生したスチームを前記スチーム通路Ｐ’に送る。前記スチームは、前記スチームパイプ６からノズル本体２２の通孔３２、スリーブ３３の通孔３５を通って、前記スチームノズル２１の噴出口３３から前記スチーム通路Ｐ’の中心軸線方向にスチームが噴出する。 Next, the operation of this embodiment will be described. First, steam is generated by a steam generating means (not shown), and the generated steam is sent to the steam passage P'. The steam flows from the steam pipe 6 through the through hole 32 of the nozzle body 22 and the through hole 35 of the sleeve 33, and is ejected from the jet port 33 of the steam nozzle 21 in the central axis direction of the steam passage P'. .

前記スチームノズル１からスチームを噴射させ続けると、前記スチーム通路Ｐ’内でスチームが凝縮し、高温で液体状の結露水が発生する。そして、この結露水の水滴が多数結合すると、この水滴が大きく成長し、スチーム流に押し出される虞がある。しかしながら、前記導水体４の第一導水部１７が、最狭部３６である前記位置決めリブ３０の通孔３２の内周面における下側、及び最狭部３６である前記スリーブ２３の通孔３５の内周面における下側に近接しているので、重力によって前記通孔３２，３５の内周面に沿って流下した水滴は、毛細管現象によって、前記溝部３１，３４の縁と前記第一導水部１７とで形成された微小な隙間に広い範囲で吸引保持される。また、結露水は、毛細管現象によって、前記位置決めリブ３０の溝部３１及び前記スリーブ２３の溝部３４にも吸引保持される。この状態では、結露水は、前記スチーム通路Ｐ’の流通面積（前記通孔３２，３５の流通面積）を殆ど狭めないので、スチーム流が結露水を勢いよく押し出すことがない。そして、更に結露水が流下して前記隙間に結露水が溜まると、この溜まった結露水がスチーム流に押されて、前記隙間から押し出される。この押し出された結露水は、前記第一導水部１７に接しているので、この第一導水部１７に沿って前記スリーブ２３（最狭部３６）の前端部から外側に移動する。そして、前記第一導水部１７に沿って外側に移動した結露水は、前記第一導水部１７と一体に設けられた前記第二導水部１８に沿って、下方に、即ち前記吸水体５に向かって流れる。更に、この第二導水部１８に沿って流れた結露水は、前記第二導水部１８と接する前記吸水体５に吸収される。このように、結露水が前記導水体４に沿って前記吸水体５に送られるので、熱い結露水が前記スチームノズル２１の噴出口３３から勢いよく噴出して顔等にかかることを抑制することができる。 If the steam is continuously jetted from the steam nozzle 1, the steam condenses in the steam passage P', and high-temperature liquid condensed water is generated. When a large number of water droplets of the condensed water combine, the water droplets grow large and may be pushed out by the steam flow. However, the first water conveying portion 17 of the water conductor 4 is located below the inner peripheral surface of the through hole 32 of the positioning rib 30 which is the narrowest portion 36 and the through hole 35 of the sleeve 23 which is the narrowest portion 36. , the water droplets that have flowed down along the inner peripheral surfaces of the through holes 32 and 35 due to gravity are caused by capillary action to flow between the edges of the grooves 31 and 34 and the first water guide. It is sucked and held over a wide range in a minute gap formed by the portion 17 . The condensed water is also attracted and held in the groove 31 of the positioning rib 30 and the groove 34 of the sleeve 23 by capillary action. In this state, the condensed water hardly narrows the circulation area of the steam passage P' (the circulation area of the through holes 32 and 35), so the steam flow does not force the condensed water out. When the condensed water further flows down and accumulates in the gap, the accumulated condensed water is pushed out from the gap by the steam flow. The extruded condensed water is in contact with the first water conveying portion 17 and therefore moves outward from the front end portion of the sleeve 23 (the narrowest portion 36 ) along the first water conveying portion 17 . Then, the condensed water that has moved outward along the first water conveying portion 17 travels downward along the second water conveying portion 18 provided integrally with the first water conveying portion 17, that is, to the water absorber 5. flow towards. Furthermore, the condensed water that has flowed along the second water guide portion 18 is absorbed by the water absorber 5 that is in contact with the second water guide portion 18 . Since the condensed water is sent to the water absorber 5 along the water conductor 4 in this way, hot condensed water is prevented from spouting vigorously from the jet port 33 of the steam nozzle 21 and splashing on the face or the like. can be done.

なお、前記結露水は、前記溝部３１，３４を経由して前記吸水体５に送られるようにすることもできる。この場合、前記溝部３１，３４の縁と前記第一導水部１７との間の微少な隙間だけでなく、前記溝部３１，３４経由でも結露水を前記吸水体５に送ることができるので、効率よく結露水を前記吸水体５に吸収させることができる。この結果、結露水をより確実に前記スチームノズル２１の噴出口３３から噴出させないようにすることができる。 The condensed water can also be sent to the water absorber 5 via the grooves 31 and 34 . In this case, the condensed water can be sent to the water absorber 5 not only through the minute gaps between the edges of the grooves 31 and 34 and the first water guide portion 17, but also through the grooves 31 and 34. Condensed water can be well absorbed by the water absorber 5 . As a result, it is possible to prevent the condensed water from being ejected from the ejection port 33 of the steam nozzle 21 more reliably.

また、前記吸水体５が吸水能力の限界を超えた場合、吸収しきれなかった結露水が水滴となって前記噴出口３３から噴出する虞があった。しかしながら、前述したように、前記溝部３１，３４に結露水が吸引保持されるので、前記吸水体５が吸水能力の限界を超えた場合、吸収しきれなかった結露水が前記溝部３１，３４に貯められることになる。そして、この溝部３１，３４に保持可能な水量を超えると、結露水は、前記溝部３１を通って前記スチームパイプ６に戻される。なお、前記スチーム通路Ｐ’は、前記位置決めリブ３０及びスリーブ２３の位置において最狭部３６となる、即ちこの最狭部３６において段差状に流通面積が絞られるので、この最狭部３６よりも上流側の水滴が前記最狭部３６を通って前記噴出口３３から噴出することはない。更に、前記溝部３１，３４の縁と第一導水部１７との間の微少な隙間に溜まった結露水は、前記第一導水部１７及び戻水部１９に沿って、前記スチームパイプ６内に戻される。この際、前述したように、前記戻水部１９が下方に曲げられるので、重力によって前記結露水の水滴を確実に前記スチームパイプ６内に戻すことができる。 In addition, when the water absorbing body 5 exceeds the limit of its water absorption capacity, there is a possibility that the condensed water that cannot be absorbed becomes water droplets and is ejected from the ejection port 33 . However, as described above, since the condensed water is sucked and held in the grooves 31 and 34, if the water absorber 5 exceeds the limit of the water absorption capacity, the condensed water that could not be absorbed will flow into the grooves 31 and 34. will be saved. When the amount of water that can be held in the grooves 31 and 34 is exceeded, the condensed water is returned to the steam pipe 6 through the grooves 31 . The steam passage P' becomes the narrowest portion 36 at the position of the positioning rib 30 and the sleeve 23. Water droplets on the upstream side do not pass through the narrowest portion 36 and are not ejected from the ejection port 33 . Furthermore, the condensed water accumulated in the minute gaps between the edges of the grooves 31 and 34 and the first water conveying portion 17 flows into the steam pipe 6 along the first water conveying portion 17 and the water return portion 19. returned. At this time, as described above, since the water return portion 19 is bent downward, the water droplets of the condensed water can be surely returned into the steam pipe 6 by gravity.

以上のように本発明は、ノズル本体２２と、このノズル本体２２におけるスチーム通路Ｐ’の最狭部３６の出口側に設けられた吸水体５と、前記スチーム通路Ｐ’の最狭部３６から前記吸水体５へ結露水を導く導水部が設けられた導水体４とを有し、この導水体４が、前記最狭部３６の内径よりも細い金属線を折り曲げて形成され、前記導水部が、第一導水部１７と第二導水部１８を有し、前記第一導水部１７が、前記スチーム通路Ｐ’の内周面における使用時に下側となる部分に沿って前記スチーム通路Ｐ’と平行に配され、前記第二導水部１８が、前記スチーム通路Ｐ’の最狭部３６の出口から使用時に下側となる方向に延びて配されるスチームノズル２１において、前記最狭部３６の内周面における使用時に下側となる部分に隙間部としての凹状の溝部３１，３４が設けられ、これらの溝部３１，３４の近傍に前記導水体４の導水部１７，１８が設けられることで、前記スチーム通路Ｐ’の最狭部３６に発生した結露水が、前記最狭部３６の内壁に沿って流下し、前記溝部３１，３４に導かれて前記吸水体５に至り、この吸水体５で吸収されるので、結露水を確実に前記吸水体５まで導いて、熱い結露水が勢いよく噴出して顔等にかかることを抑制することができる。また、前記溝部３１，３４によって、前記吸水体５に導かれる結露水の量が多くなるので、結露水の発生が多くなっても、確実に前記吸水体５に結露水を吸水させることができる。更に、前記溝部３１，３４においても結露水を保持することができるので、熱い結露水が噴出することをより確実に抑制することができる。 As described above, according to the present invention, the nozzle body 22, the water absorber 5 provided on the outlet side of the narrowest portion 36 of the steam passage P' in the nozzle body 22, and the water from the narrowest portion 36 of the steam passage P' and a water conductor 4 provided with a water guide portion for guiding condensed water to the water absorber 5, the water guide 4 being formed by bending a metal wire thinner than the inner diameter of the narrowest portion 36, and forming the water guide portion. has a first water conveying portion 17 and a second water conveying portion 18, and the first water conveying portion 17 extends along the inner peripheral surface of the steam passage P' at the lower side during use. in the steam nozzle 21 in which the second water conveying portion 18 extends downward during use from the outlet of the narrowest portion 36 of the steam passage P′. concave grooves 31 and 34 as gaps are provided in the portion of the inner peripheral surface that will be on the lower side during use, and the water conveying portions 17 and 18 of the water conductor 4 are provided in the vicinity of these grooves 31 and 34. Then, the condensed water generated in the narrowest portion 36 of the steam passage P′ flows down along the inner wall of the narrowest portion 36, is guided by the grooves 31 and 34, and reaches the water absorber 5. Since it is absorbed by the body 5, the condensed water can be surely led to the water absorber 5, and the hot condensed water can be prevented from spouting vigorously and splashing on the face or the like. Further, since the amount of condensed water led to the water absorber 5 is increased by the grooves 31 and 34, even if the amount of condensed water increases, the water absorber 5 can surely absorb the condensed water. . Furthermore, since the condensed water can be held in the grooves 31 and 34 as well, it is possible to more reliably prevent hot condensed water from blowing out.

また、本発明は、前記スチーム通路の最狭部３６が筒状のスリーブ２３で構成されると共に、このスリーブ２３に隙間部としての溝部３４が形成されることで、間隙寸法の小さな溝部３４を容易に構成することができる。
