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。 The present invention relates to a steam nozzle used in a steam-type beauty device or the like that injects 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式美容器では、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, those used in a steam type cosmetologist or the like that blows steam generated by a steam generator from the nozzle onto the face of the person to be treated are known (see, for example, Patent Document 1). .). In such a steam type beauty device, steam condenses at the nozzle to form high-temperature water droplets, and the water droplets may be ejected from the nozzle together with the steam flow and hit the face of the person to be treated. A water absorber is provided on the outlet side of the steam passage, and a water guide for guiding water droplets to the water supply body is provided in the steam passage, and the water droplets are absorbed by the water absorber so that the water droplets are not ejected from the nozzle. It is configured.

しかしながら、このようなスチーム式美容器においては、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 type beauty device, when the amount of high-temperature dew condensation water pushed out by the ejected steam stream is larger than the amount of dew condensation water that can be absorbed by the water absorber, dew condensation is formed on the water absorber. There was a risk that the water could not be completely absorbed and hot water droplets would be ejected over the water absorber.

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式美容器を提供することを目的とする。 An object of the present invention is to solve the above problems and to provide a safe steam type beauty device capable of reliably absorbing condensed water into a water absorber.

本発明の請求項１に記載のスチーム式美容器は、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。 The steam-type beauty device according to claim 1 of the present invention includes a nozzle body, a water absorber provided on the outlet side of the narrowest portion of the steam passage in the nozzle body, and the water absorption from the narrowest portion of the steam passage. It has a water guide body provided with a water guide portion that guides condensed water to the body, and this water guide body is formed by bending a metal wire thinner than the inner diameter of the narrowest portion, and the water guide portion is the first water guide portion. The first water guide is arranged in parallel with the steam passage along a portion that is lower when used on the inner peripheral surface of the steam passage. In the steam nozzle that extends from the outlet of the narrowest portion of the steam passage in the direction of the lower side during use, a gap portion is provided in the portion that becomes the lower side during use on the inner peripheral surface of the narrowest portion. A water guiding portion of the water guiding body is provided in the vicinity of the gap 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、前記スチーム経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。 Further, in the steam nozzle according to claim 2 of the present invention, in claim 1, the narrowest portion of the steam path is formed of a tubular sleeve, and the gap portion is formed in the sleeve. is there.

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。 Further, in the steam nozzle according to claim 3 of the present invention, in claim 2, the gap portion has a slit shape.

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。 Further, in the steam nozzle according to claim 4 of the present invention, the gap portion is concave in claim 2.

更に、本発明の請求項５に記載のスチーム式美容器は、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, in the steam type beauty device according to claim 5 of the present invention, in any one of claims 1 to 4, the gap portion has a size that causes a capillary phenomenon.

本発明の請求項１に記載のスチーム式美容器は、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-type beauty device according to claim 1 of the present invention is configured as described above, so that the condensed water generated in the narrowest portion of the steam passage flows down along the inner wall of the narrowest portion. Since it is guided to the gap and reaches the water absorber and is absorbed by the water absorber, the condensed water is surely guided to the water absorber and the hot condensed water is prevented from being vigorously ejected and applied to the face or the like. can do. Further, since the amount of dew condensation water guided to the water absorbing body is increased by the gap portion, the dew condensation water can be surely absorbed by the water absorbing body even if the amount of dew condensation water generated is large. Further, since the dew condensation water can be retained even in the gap portion, it is possible to more reliably suppress the ejection of hot dew condensation water.

なお、前記スチーム経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。 The narrowest portion of the steam path is formed of a tubular sleeve, and the gap is formed in the sleeve, so that a gap having a small gap size can be easily formed.

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。 Further, since the gap portion has a slit shape, the condensed water guided to the gap portion along the inner wall of the narrowest portion can be efficiently made to follow the water guiding portion of the water guide body. 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。 Further, since the gap portion has a concave shape, the condensed water can be guided from the water guiding portion of the water guiding 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。 Further, since the gap portion is sized to cause a capillary phenomenon, the condensed water guided to the gap portion 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。 Hereinafter, the first embodiment of the present invention will be described with reference to FIGS. 1 to 3. In this embodiment, the left side of FIG. 2A is defined as the front and the right side is defined as the rear. Reference numeral 1 denotes a steam nozzle of the present invention. The steam nozzle 1 has a nozzle body 2, a sleeve 3, a water guide body 4, a water absorbent body 5, and a steam pipe 6. The steam pipe 6 is connected to a steam generating means (not shown). Then, the steam generated by the steam generating means is ejected through the steam passage P provided in the steam nozzle 1.

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 step 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 open in the axial direction. Then, a flange-shaped positioning rib 10 is formed on the inner surface of the small diameter portion 7. A slit-shaped notch 11 as a gap is formed in the lower portion of the positioning rib 10. In the present invention, the slit shape means a completely separated state. That is, the positioning rib 10 is separated in the axial direction by the notch 11. Further, a steam through 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. Further, the large diameter portion 8 is formed in a short cylindrical shape having a larger diameter than the small diameter portion 7 and having both ends open in the axial direction. Then, the front end of the large diameter portion 8 becomes the spout 13. Further, the step portion 9 is formed so as to project in a flange shape from the front end of the small diameter portion 7 to the outside and from the rear end to the inside of the large diameter portion 8.

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 formed of a metal such as brass into a substantially cylindrical shape with both ends open in the axial direction, and is inserted into the small diameter portion 7. Then, the rear end of the sleeve 3 comes into contact with the positioning rib 10 and is positioned. In this state, the front end of the sleeve 3 is at substantially the same position as the front end of the small diameter portion 7. Further, a slit-shaped notch 14 as a gap is formed in the lower portion of the sleeve 3. That is, the sleeve 3 is cut off in the axial direction by the slit-shaped notch 11, and the axial cross-sectional shape becomes C-shaped as shown in FIG. 2 (b). Further, 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 positions of the through holes 12 and the through holes 15 are the narrowest portions 16 of the steam passage P. Further, the notch 11 of the positioning rib 10 and the notch 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 guide body 4 is attached so as to pass through the steam passage P. The water guide body 4 is formed by bending a single metal wire smaller than the inner diameter of the through hole 15 of the sleeve 3, that is, the narrowest portion 16. Therefore, the water guide body 4 is easily and inexpensively formed. Then, as shown in FIGS. 2A and 3, the water guide body 4 has a linear first water guide portion 17 substantially parallel to the axial direction of the steam passage P and the first water guide portion 17. A linear second water guiding portion 18 formed by bending downward in the axial direction on the outlet side, and a linear returning portion formed by bending downward on the inlet side of the first water guiding portion 17. 19 and an annular portion 20 extending around the axis of the steam passage P from the tip end portion of the second water guiding portion 18. Then, the first water conveyance portion 17 is arranged in parallel with the notch portions 11 and 14. Further, the second water conveyance portion 18 is arranged in parallel with 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 absorbing body 5 is formed of a water absorbing material such as felt in a ring shape, and is inserted inside the large diameter portion 8 and in front of the step portion 9. The outer diameter of the water absorbing body 5 is formed to be substantially equal to the inner diameter of the large diameter portion 8. Further, the inner diameter of the water absorbing body 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 silicon rubber. As described above, since the steam pipe 6 has heat resistance and flexibility, it is possible to pass high-temperature steam, and the direction of the steam nozzle 1 can be changed.

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. The steam is ejected from the steam pipe 6 through the through hole 12 of the nozzle body 2 and the through hole 15 of the sleeve 3 from the ejection port 13 of the steam nozzle 1 in the direction of the central axis 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。 When steam is continuously injected from the steam nozzle 1, steam is condensed in the steam passage P, and liquid dew condensation water is generated at a high temperature. Then, when a large number of water droplets of the condensed water are combined, the water droplets may grow large and be pushed out into the steam flow. However, the first water guiding portion 17 of the water guiding body 4 is the lower side of the inner peripheral surface of the through hole 12 of the positioning rib 10 which is the narrowest part 16, and the through hole 15 of the sleeve 3 which is the narrowest part 16. Since it is close to the lower side of the inner peripheral surface of the above, the water droplets that have flowed down along the inner peripheral surfaces of the through holes 12 and 15 due to gravity are caused by the capillary phenomenon to the edges of the notches 11 and 14 and the first. It is sucked and held in a wide range in a minute gap formed by the water guiding portion 17. Further, the condensed water is sucked and held in the notch 11 of the positioning rib 10 and the notch 14 of the sleeve 3 due to the capillary phenomenon. In this state, the dew condensation water hardly narrows the distribution area of the steam passage P (the distribution area of the through holes 12 and 15), so that the steam flow does not vigorously push out the dew condensation water. Then, when the condensed water further flows down and the condensed water accumulates in the gap, the accumulated condensed water is pushed by the steam flow and pushed out from the gap. Since the extruded dew condensation water is in contact with the first headrace portion 17, it moves outward from the front end portion of the sleeve 3 (narrowest portion 16) along the first headrace portion 17. Then, the condensed water that has moved outward along the first water guiding portion 17 is sent downward along the second water conducting portion 18 provided integrally with the first water conducting portion 17, that is, to the water absorbing body 5. It flows toward. Further, the condensed water flowing along the second water conducting portion 18 is absorbed by the water absorbing body 5 in contact with the second water conducting portion 18. In this way, since the condensed water is sent to the water absorbing body 5 along the water guiding body 4, it is possible to prevent the hot condensed water from being vigorously ejected from the ejection port 13 of the steam nozzle 1 and being applied to 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 may be sent to the water absorbing body 5 via the notches 11 and 14. In this case, the condensed water can be sent to the water absorbing body 5 not only through the minute gap between the edges of the notches 11 and 14 and the first water guiding portion 17, but also via the notches 11 and 14. , Condensed water can be efficiently absorbed by the water absorbing body 5. As a result, it is possible to more reliably prevent the condensed water from being ejected from the ejection port 13 of the steam nozzle 1.

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。 Further, when the water absorbing body 5 exceeds the limit of the water absorbing capacity, there is a possibility that the condensed water that could not be absorbed becomes water droplets and is ejected from the spout 13. However, as described above, since the dew condensation water is sucked and held in the notch portions 11 and 14, when the water absorbing body 5 exceeds the limit of the water absorption capacity, the dew condensation water that could not be absorbed is sucked and held in the notch portions 11 and 14. It will be stored in 14. Then, when the amount of water that can be held in the notches 11 and 14 is exceeded, the condensed water is returned to the steam pipe 6 through the notches 11. The steam passage P becomes the narrowest portion 16 at the positions of the positioning rib 10 and the sleeve 3, that is, the distribution area is narrowed in a stepped shape at the narrowest portion 16, so that the steam passage P is upstream from the narrowest portion 16. Water droplets on the side do not spout from the spout 13 through the narrowest portion 16. Further, the condensed water collected in the minute gap between the edges of the cutout portions 11 and 14 and the first headrace portion 17 is formed in the steam pipe 6 along the first water guide portion 17 and the return water portion 19. 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 reliably returned to the steam pipe 6 by gravity.

以上のように本発明は、ノズル本体２と、このノズル本体２におけるスチーム通路Ｐの最狭部１６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１６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１６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１６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１において、前記最狭部１６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スリット状の切欠部１１，１４が設けられ、この切欠部１１，１４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１６に発生した結露水が、前記最狭部１６の内壁に沿って流下し、前記切欠部１１，１４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、前記切欠部１１，１４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、前記切欠部１１，１４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, in the present invention, the nozzle body 2, the water absorbing body 5 provided on the outlet side of the narrowest portion 16 of the steam passage P in the nozzle main body 2, and the water absorbing body 16 from the narrowest portion 16 of the steam passage P.

It has a first water conducting unit 17 and a second water conducting unit 18, and the first water conducting unit 17 is arranged parallel to the steam passage P along a portion that is lower when used on the inner peripheral surface of the steam passage P. In the steam nozzle 1 in which the second water guiding portion 18 is arranged so as to extend downward from the outlet of the narrowest portion 16 of the steam passage P in use, the inner peripheral surface of the narrowest portion 16 is formed. Slit-shaped cutouts 11 and 14 as gaps are provided in the lower portion at the time of use, and the water guide portions 17 and 18 of the water guide body 4 are provided in the vicinity of the cutouts 11 and 14, whereby the said Condensation water generated in the narrowest portion 16 of the steam passage P flows down along the inner wall of the narrowest portion 16 and is guided by the notches 11 and 14 to reach the water absorbent 5, and the water absorbent 5 Since it is absorbed, it is possible to surely guide the condensed water to the water absorbing body 5 and prevent the hot condensed water from being vigorously ejected and applied to the face or the like. Further, since the amount of dew condensation water guided to the water absorbing body 5 is increased by the cutout portions 11 and 14, even if the amount of dew condensation water is increased, the water absorbing body 5 can surely absorb the dew condensation water. it can. Further, since the dew condensation water can be retained in the notches 11 and 14, it is possible to more reliably suppress the ejection of hot dew condensation water.

また、本発明は、前記スチーム経路の最狭部１６が筒状のスリーブ３で構成されると共に、このスリーブ３に隙間部としての切欠部１４が形成されることで、間隙寸法の小さな切欠部１４を容易に構成することができる。 Further, in the present invention, the narrowest portion 16 of the steam path is composed of a tubular sleeve 3, and a notch portion 14 as a gap portion is formed in the sleeve 3, so that the notch portion having a small gap size is formed. 14 can be easily configured.

また、本発明は、前記切欠部１４がスリット形状とされることで、前記最狭部１６の内壁に沿って前記切欠部１４に導かれる結露水を、効率的に前記導水体４の導水部１７，１８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５まで導くことができる。 Further, in the present invention, since the cutout portion 14 has a slit shape, the condensed water guided to the cutout portion 14 along the inner wall of the narrowest portion 16 can be efficiently discharged to the water guiding portion of the water guiding body 4. Since it can be aligned with 17 and 18, the condensed water can be surely guided to the water absorbing body 5.

更に、本発明は、前記切欠部１４が毛細管現象を生じる寸法とされることで、前記切欠部１４に導かれた結露水を確実に前記吸水体５まで導くことができる。 Further, in the present invention, since the notch portion 14 has a size that causes a capillary phenomenon, the condensed water guided to the notch portion 14 can be surely guided to the water absorbing body 5.

次に、本発明の第二の実施形態について、図４及び図５に基づいて説明する。なお、本実施形態において、図５（ａ）の左側を前、右側を後と規定する。２１は本発明のスチームノズルである。このスチームノズル２１は、ノズル本体２２と、スリーブ２３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２１内に設けられたスチーム通路Ｐ’を通過して噴出される。 Next, the second embodiment of the present invention will be described with reference to FIGS. 4 and 5. In this embodiment, the left side of FIG. 5A is defined as the front and the right side is defined as the rear. Reference numeral 21 denotes a steam nozzle of the present invention. The steam nozzle 21 has a nozzle body 22, a sleeve 23, a water guiding body 4, a water absorbing body 5, and a steam pipe 6. The steam pipe 6 is connected to a steam generating means (not shown). Then, the steam generated by the steam generating means is ejected through the steam passage P'provided in the steam nozzle 21.

前記ノズル本体２２は、合成樹脂によって形成される。そして、前記ノズル本体２２は、後側の径小部２７と、前側の径大部２８と、これら径小部２７と径大部２８との間に設けられる段差部２９とを有する。前記径小部２７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２７の内面には、フランジ状の位置決めリブ３０が形成される。なお、この位置決めリブ３０の下部には、隙間部としての凹状の溝部３１が形成される。ここで言う凹状とは、第一の実施形態のスリット状とは異なり、一部が繋がった状態で凹んだ形状を指す。即ち、前記位置決めリブ３０は、その下部において、一部が繋がる。更に、前記位置決めリブ３０の中央部には、スチームの通孔３２が形成される。そして、前記溝部３１と通孔３２は繋がる。また、前記径大部２８は、前記径小部２７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２８の前端が噴出口３３となる。更に、前記段差部２９は、前記径小部２７の前端から外側に、且つ前記径大部２８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 22 is made of synthetic resin. The nozzle body 22 has a small diameter portion 27 on the rear side, a large diameter portion 28 on the front side, and a step portion 29 provided between the small diameter portion 27 and the large diameter portion 28. The small diameter portion 27 is formed in a short cylindrical shape with both ends open in the axial direction. Then, a flange-shaped positioning rib 30 is formed on the inner surface of the small diameter portion 27. A concave groove 31 as a gap is formed in the lower portion of the positioning rib 30. The concave shape referred to here refers to a concave shape in a partially connected state, unlike the slit shape of the first embodiment. That is, a part of the positioning rib 30 is connected at the lower portion thereof. Further, a steam through hole 32 is formed in the central portion of the positioning rib 30. Then, the groove portion 31 and the through hole 32 are connected. Further, the large diameter portion 28 is formed in a short cylindrical shape having a larger diameter than the small diameter portion 27 and having both ends open in the axial direction. Then, the front end of the large diameter portion 28 becomes the spout 33. Further, the step portion 29 is formed so as to project in a flange shape from the front end of the small diameter portion 27 to the outside and from the rear end of the large diameter portion 28 to the inside.

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 formed of a metal such as brass into a substantially cylindrical shape with both ends open in the axial direction, and is inserted into the small diameter portion 27. Then, the rear end of the sleeve 23 comes into contact with the positioning rib 30 and is positioned. In this state, the front end of the sleeve 23 is at substantially the same position as the front end of the small diameter portion 27. Further, a concave groove 34 as a gap is formed in the lower part of the inner surface of the sleeve 23. The groove 34 is formed parallel to the axial direction of the sleeve 23. Further, unlike the first embodiment, the sleeve 23 is partially connected on the outer peripheral side of the groove portion 34. Further, a through hole 35 is formed in the central portion of the sleeve 23 in the axial direction. That is, the groove 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 positions of the through hole 32 and the through hole 35 are the narrowest portion 36 of the steam passage P'. Further, the groove 31 of the positioning rib 30 and the groove 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 guide body 4 is attached so as to pass through the steam passage P'. The water guide body 4 is formed by bending a single metal wire smaller than the inner diameter of the through hole 35 of the sleeve 23, that is, the narrowest portion 36. Therefore, the water guide body 4 is easily and inexpensively formed. Then, the water guide body 4 is bent downward in the axial direction toward the outlet side of the linear first water guide portion 17 which is substantially parallel to the axial direction of the steam passage P'and the first water guide portion 17. A linear second headrace portion 18 formed by the water guide portion 18, a linear water return portion 19 formed by being bent downward toward the inlet side of the first headrace portion 17, and a tip portion of the second headrace portion 18. It is configured to have an annular portion 20 extending around the axis of the steam passage P. The first water conveyance portion 17 is arranged in parallel with the groove portions 31 and 34. Further, the second water guiding portion 18 is arranged in parallel with the groove portion 34.

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２８の内側で且つ前記段差部２９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２８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２７の内径よりも大きく形成される。 The water absorbing body 5 is formed in a ring shape with a water absorbing material such as felt, and is inserted inside the large diameter portion 28 and on the front side of the step portion 29. The outer diameter of the water absorbing body 5 is formed to be substantially equal to the inner diameter of the large diameter portion 28. Further, the inner diameter of the water absorbing body 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 silicon rubber. As described above, since the steam pipe 6 has heat resistance and flexibility, it is possible to pass high-temperature steam and the direction of the steam nozzle 21 can be changed.

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 is ejected 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 from the ejection port 33 of the steam nozzle 21 in the direction of the central axis 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。 When steam is continuously injected from the steam nozzle 1, steam is condensed in the steam passage P', and liquid dew condensation water is generated at a high temperature. Then, when a large number of water droplets of the condensed water are combined, the water droplets may grow large and be pushed out into the steam flow. However, the first water guide portion 17 of the water guide body 4 is the lower side of 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. Since it is close to the lower side of the inner peripheral surface of the water droplets, 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 the capillary phenomenon to the edges of the grooves 31 and 34 and the first water guide. It is sucked and held in a wide range in a minute gap formed by the portion 17. Further, the condensed water is sucked and held in the groove portion 31 of the positioning rib 30 and the groove portion 34 of the sleeve 23 due to the capillary phenomenon. In this state, the dew condensation water hardly narrows the distribution area of the steam passage P'(the distribution area of the through holes 32 and 35), so that the steam flow does not vigorously push out the dew condensation water. Then, when the condensed water further flows down and the condensed water accumulates in the gap, the accumulated condensed water is pushed by the steam flow and pushed out from the gap. Since the extruded dew condensation water is in contact with the first headrace portion 17, it moves outward from the front end portion of the sleeve 23 (narrowest portion 36) along the first headrace portion 17. Then, the condensed water that has moved outward along the first water guiding portion 17 is sent downward along the second water conducting portion 18 provided integrally with the first water conducting portion 17, that is, to the water absorbing body 5. It flows toward. Further, the condensed water flowing along the second water conducting portion 18 is absorbed by the water absorbing body 5 in contact with the second water conducting portion 18. In this way, since the condensed water is sent to the water absorbing body 5 along the water guiding body 4, it is possible to prevent the hot condensed water from being vigorously ejected from the ejection port 33 of the steam nozzle 21 and being applied to 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 may be sent to the water absorbing body 5 via the grooves 31 and 34. In this case, the dew condensation water can be sent to the water absorbing body 5 not only through the minute gap between the edges of the groove portions 31 and 34 and the first water guiding portion 17, but also via the groove portions 31 and 34, so that the efficiency is high. Condensed water can be well absorbed by the water absorber 5. As a result, it is possible to more reliably prevent the condensed water from being ejected from the ejection port 33 of the steam nozzle 21.

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。 Further, when the water absorbing body 5 exceeds the limit of the water absorbing capacity, there is a possibility that the condensed water that could not be absorbed becomes water droplets and is ejected from the spout 33. However, as described above, since the dew condensation water is sucked and held in the grooves 31 and 34, when the water absorbing body 5 exceeds the limit of the water absorption capacity, the dew condensation water that could not be completely absorbed is sucked and held in the grooves 31 and 34. It will be saved. Then, 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 groove 31. The steam passage P'becomes the narrowest portion 36 at the positions of the positioning rib 30 and the sleeve 23, that is, the distribution area is narrowed in a stepped shape at the narrowest portion 36, so that the steam passage P'is more than the narrowest portion 36. Water droplets on the upstream side do not eject from the spout 33 through the narrowest portion 36. Further, the condensed water collected in the minute gap between the edges of the grooves 31 and 34 and the first water guide portion 17 is put into the steam pipe 6 along the first water guide portion 17 and the return water portion 19. Be 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 reliably returned to 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, the present invention comprises the nozzle body 22, the water absorbing body 5 provided on the outlet side of the narrowest portion 36 of the steam passage P'in the nozzle body 22, and the narrowest portion 36 of the steam passage P'. It has a water guide body 4 provided with a water guide portion for guiding dew condensation water to the water absorption body 5, and the water guide body 4 is formed by bending a metal wire thinner than the inner diameter of the narrowest portion 36, and the water guide portion.
