Description

【0001】
【発明の属する技術分野】
本発明は、スチーム式の美容器、美顔器、吸入器等のスチーム発生器具に関するものである。
【0002】
【従来の技術】
一般にスチーム式の美容器、美顔器、吸入器等の器具は、ボイラーで発生させたスチームをスチーム流路を介してノズルから人体に向けて噴出さえることになるために、結露水滴(湯玉)が吹き出してしまうと火傷の虞があり、このために上記用途の器具は結露水滴の噴き出しを防ぐものになっていなればならない(結露水滴の噴き出しを防ぐものとして本特許出願人が先に出願した特開平11−4869号公報等がある)。
【0003】
従来、結露水滴が噴き出さないようにするために結露復水管を設けてボイラーに復水するようにしたものがあるが、これらは図9のような構造になっている。ヒータを内蔵するボイラーaのスチーム室bの上部からスチーム流路cが延設されており、スチームを噴き出すノズルd及びスチーム流路cに発生する結露を復水するためにスチーム流路cにはボイラーa下部と接続された結露復水管eを設けてあり、ノズルdはスチーム流路cと結露復水管eを繋いだ管の上部より突出した管路の先端に配置されている。
【0004】
またスチームをイオン化させる機能を持ったスチーム発生器具もある。その構造例としては、上記ボイラーaからスチームを送るスチーム流路cに放電極fを設け、スチーム発生装置外部設けた高電圧発生装置により放電極f間に高電圧をかけることにより放電極f間を通るスチームをイオン化させる構造になっている。従来は、この放電極fがスチーム通路cの横方向の管路c1に設けられていた。
【0005】
また器具の使用後にボイラー内部の残水を排水する機能を持った器具がある。構造例としては、結露復水管に排水口を設け、排水口と結露復水管との間に開閉可能は弁を設けてある。
【0006】
【発明が解決しようとする課題】
ところで、上記従来の構造では、スチーム室bより発生したスチームが横方向の管路c1を通って上方向の管路c2を通ってノズルdに到達する。スチーム室bからノズルdの間で発生した結露はスチームの勢いに伴ってノズルd方向に運ばれるものであり、スチーム流路cが上及び横方向の管路c1,c2で構成されていると、ノズルdに結露が到達しやすいという問題がある。
【0007】
また、スチームをイオン化させる機能を持ったスチーム発生装置においては、イオン化させるための放電極fがスチーム流路cの横方向の管路c1に設けてあるため、管路c1に発生した結露が管路c1にたい積しやすいので、結露が放電極fに付着しやすく、放電極fに結露が付着した場合は放電しにくくなり、スチームのイオン化ができなくなる。
【0008】
またボイラーのヒータにより水を沸騰させた際に水に含まれたカルシウムイオンが固体化したカルシウムとなってボイラー内に析出するが、ボイラー内部の残水を排水する機能を持った器具においては、上記のように析出したカルシウムが排水する際に弁に挟まることがあり、弁の閉状態にて弁から水漏れが発生する可能性がある。
【0009】
本発明は叙述の点に鑑みてなされたものであって、結露がノズルより突出しにくく、またスチームをイオン化するものにおいては安定してスチームをイオン化でき、さらに排水機能を有したものにおいては弁より水漏れの起こらないスチーム発生器具を提供することを課題とする。
【0010】
【課題を解決するための手段】
上記課題を解決するため本発明のスチーム発生器具は、水を加熱して気化させるボイラーの下部に水を貯留する貯留室を有し、ボイラーに備えた沸騰室で発生させたスチームを噴出させるスチーム室をこの貯留室の上部に設け、ボイラーで発生したスチームを噴出するためのノズルと、ボイラーのスチーム室から上記ノズルにスチームを供給するスチーム流路と、ノズルやスチーム流路に結露した結露水をボイラーの貯留室に復水するため、上部縦管路部と絞り管路部と下部縦管路部とからなる垂直部分と横管路部とで構成され且つその上部縦管路部を前記スチーム流路と兼ねる結露復水管とを設け、スチーム流路の前記結露復水管の垂直な上部縦管路部を兼ねる部分の下部に連通するようにノズルを配置したことを特徴とする。ノズルを結露復水管の垂直部分の途中に配置したことにより、結露を伴ったスチームの流れをノズルに到達する前に鉛直下方にして、結露が下方に存在する水に滴下させやすくでき、結露がノズルに到達するのを防ぐことができる。
【0011】
また結露復水管とボイラーとの間のスチーム流路にはボイラーの上方向に凸となった逆U字状のU字管路を有することを特徴とすることも好ましい。スチーム流路に発生した結露はU字管路を乗り超えないとノズルに行くことができないためにノズル付近に行きにくくなる。また、スチームの流れがU字管路に通されることにより、下方に流れが整流されるためにU字管路の頂点を越えた結露がノズル側に行きにくくなる。
【0012】
またスチーム流路の前記結露復水管の垂直な上部縦管路部を兼ねる部分の下部のノズルへ接続する位置よりも高い位置にスチームをイオン化させる放電極を配置したことを特徴とすることも好ましい。放電極を従来の結露の溜まりやすい横方向のスチーム流路から垂直部分に配置を変えることにより、放電極下に結露が溜まって放電極と結露とが触れることを防ぐことができる。
【0013】
また結露復水管とボイラーとの間のスチーム流路に吸水体を設けたことを特徴とすることも好ましい。U字管路の頂点より下方のボイラー側に結露がたい積した場合、結露が多量にたい積するとスチームの勢いで結露表面がU字管路の下端から頂点の間に波打ち、膜を張っては膜が割れてボコボコ音が発生し、且つスチーム流路を遮ることによりスチーム発生量の低下を起こすことがあるが、上記のようにU字管路の頂点より下方のボイラー側のスチーム流路に吸水体を設けることにより、発生した結露がボイラーに復水しやすくなり、スチーム流路に多量の結露がたい積するのを防ぐことができる。
【0014】
また逆U字状のU字管路において、U字管路の頂点より下部で且つボイラー側の管路に小径部を設けたことを特徴とすることも好ましい。U字管路の頂点より下方のボイラー側に結露がたい積した場合、結露が多量にたい積するとスチームの勢いで結露表面がU字管路の下端から頂点の間に波打ち、膜を張っては膜が割れてボコボコ音が発生し、且つスチーム流路を遮ることによりスチーム発生量の低下を起こすことがあるが、上記のようにU字管路の頂点より下部で且つボイラー側の管路に小径部を設けることで、膜を張る位置のスチーム流速を上げることができ、U字管路を越えそうな不安定な結露を速い速度で結露復水管に送ることができ、スチーム流路に多量の結露がたい積するを防ぐことができる。
【0015】
またスチームを発生するための沸騰室と、沸騰させる水を貯留する貯留室とを分離し、沸騰室に貯留室から水を供給する穴と、沸騰室にて発生したスチームを貯留室の上部のスチーム室に噴出させる噴出口とで沸騰室と貯留室やスチーム室とが連結されたボイラーにおいて、スチーム室の天井面にスチーム流路の入口を設け、スチーム室のスチームがスチーム流路に入るのに迂回させるための垂下壁をこの入口縁から下方に突設したことを特徴とする。貯留室から供給された水を沸騰室で沸騰させて発生したスチームをスチーム室に噴出することにより徐々に水を沸騰させることによりスチームの発生時間を速めることができる構造のスチーム発生装置においては、沸騰室から発生したスチームに伴って沸騰水がスチーム室に流れ込んでくる際にスチーム室に連通したスチーム流路にスチームの流れに伴って沸騰水が入り込むことがあるが、スチーム流路の入口にスチーム室内側に突出させた壁を設けることにより、沸騰水がスチーム流路に流れ込むのを防止できる。
【0016】
また結露復水管の下部縦管路部と横管路部との間の部分からボイラー内の水を外部に排水する排水管を連出し、ボイラー下部の結露復水管の横管路部と連通させる開口にフィルターを設けたことを特徴とすることも好ましい。カルシウムが析出してもフィルターで捕集して排水口の弁が詰まるのを防止できる。
【0017】
またボイラー内の水を貯留する貯留室の底面に結露復水管の横管路部とを連通させる開口を設け、この貯留室の底面に上記開口を下端とする勾配を設けたことを特徴とすることも好ましい。ボイラー底面の水を勾配にて水が残らないようにスムーズに排水でき、ボイラー内を乾燥する際に発生する固形カルシウムを低減させて排水口の弁が詰まるのを防止できると共に使用者の水抜き作業を緩和することができる。
【0018】
【発明の実施の形態】
本発明のスチーム発生器具は、スチーム式の美容器、美顔器、吸収器等であるが、本例の場合、スチーム式の美容器具の例について述べる。
【0019】
先ず図1の例から説明する。美容器具は水を気化してスチームを発生するボイラー1と、ボイラー1で発生したスチームを噴出するためのノズル2と、ボイラー1からノズル2にスチームを供給するスチーム流路3に接続された結露復水管4とを具備する。ボイラー1は後述するように下部の貯留室5に貯留した水がヒータ6を有する沸騰室7で沸騰させられ、沸騰室7で沸騰することで沸騰したスチームがスチーム室8を介してスチーム流路3に供給されるようになっている。ボイラー1で発生したスチームはスチーム流路3を介してノズル2に供給されるようになっている。またノズル2やスチーム流路3に結露した結露水を復水する結露復水管4はスチーム流路3とボイラー1の貯留室5の底部を連通させるように形成されている。本例の場合、結露復水管4は、スチーム流路3と兼ねる上部縦管路部4aと、その下の絞り管路部4bと、その下の下部縦管路部4cと、下部縦管路部4cの下端と貯留室5とを連通させる横管路部4dとで構成されている。
【0020】
本発明の場合、スチーム流路3の前記結露復水管4の垂直な上部縦管路部4aを兼ねる部分の下部に連通するようにノズル2を配置してある。またノズル2は先端程上になるように斜め上方を向けてある。このようにノズル2を配置してあると、結露を伴ったスチームの流れをノズル2に到着する前に鉛直下方にして、結露水が下方に存在する水に滴下させやすくすることができ、結露がノズル2に到達するを防ぐことができる。またスチームをイオン化するための放電極10が結露復水管4の上部縦管路部4aに配置してあり、放電極10に結露が付着しにくく、放電が安定して行われ、安定してスチームをイオン化できる。
【0021】
次に図2に示す例について述べる。本例も上記例と基本的に同じであり、異なる点だけを述べる。本例の場合、スチーム流路3の途中には上方に凸となった逆U字状のU字管路11を設けてある。U字管路11の頂点からノズル2側の管路はスチーム流路3と結露復水管路4の上部縦管路部4aと兼ねている。そして本例の場合も結露復水管路4の上部縦管路部4aの下部と連通するようにノズル2を設けてある。この場合も結露を伴ったスチームの流れをノズル2に到着する前に鉛直下方にして、結露水が下方に存在する水に滴下させやすくすることができ、結露がノズル2に到達するを防ぐことができる。またスチーム流路3に発生した結露はU字管路11を乗り超えないとノズル2に行くことができないためにノズル2付近に行きにくくなる。またスチームの流れがU字管路11を通すことにより下方の流れに整流されるために、U字管路11の頂点を乗り越えた結露がノズル2側に行きにくくなる。またスチームをイオン化するための放電極10が結露復水管4の上部縦管路部4aに配置してあり、放電極10に結露が付着しにくく、放電が安定して行われ、安定してスチームをイオン化できる。
【0022】
次に図3に示す例について述べる。本例も上記例と基本的に同じであり、異なる点だけ述べる。本例の場合、U字管路11の頂点より下方のボイラー1側のスチーム流路3にスポンジのような吸水体12を配置してあり、吸水体12の一端をスチーム室8側の入口13に臨ませてある。U字管路11の頂点よりボイラー1側の結露Wが図3(b)のようにたい積した場合、結露Wが多量にたい積するとスチームの勢いで結露W表面がU字管路11下端から頂点の間で波を打ち、膜W1を張っては膜W1が割れてボコボコ音が発生し、且つスチーム流路3を遮ることによりスチームの発生量の低下を起こすことがあるが、上記のように吸水体12を設けることにより、結露を吸水体12に吸水してボイラー1に復水しやすくなり、スチーム流路3に多量の結露Wがたい積するのを防ぐことができる。
【0023】
次に図4、図5に示す例について述べる。本例も上記例と基本的に同じであり、異なる点だけを述べる。本例の場合、結露復水管4の下部縦管路部4cと横管路部4dとの間の部分から排水管14を連出してあり、排水管14の端部に排水弁15を設けてある。排水弁15は弁筐体16に排水口17と流入口18を設け、排水口17を開閉する弁部材19を弁筐体16内に摺動自在に配設してある。弁部材19には摺動自在な鉄心20を連結してあり、コイル21を励磁することによりバネ22に抗して排水口17を開くようになっている。これにより器具を使用しないときには排水口17を開いてボイラー1内の水を外部に排水することができる。
【0024】
次に図6に示す例について述べる。本例も上記例を基本的に同じであり、異なる点だけを述べる。本例の場合、U字管路11の頂点より下部でボイラー1側のスチーム流路3に小径部27を設けてある。図3(b)のようにU字管路11の頂点より下方のボイラー1側に結露Wがたい積した場合、結露Wが多量にたい積するとスチームの勢いで結露W表面がU字管路11の下端から頂点の間に波打ち、膜W1を張っては膜W1が割れてボコボコ音が発生し、且つスチーム流路3を遮ることによりスチーム発生量の低下を起こすことがあるが、上記のようにU字管路11の頂点より下部で且つボイラー1側の管路に小径部27を設けることで、膜W1を張る位置のスチーム流速を上げることができ、U字管路11を越えそうな不安定な結露Wを速い速度で結露復水管4に送ることができ、スチーム流路3に多量の結露Wがたい積するを防ぐことができる。
【0025】
次に図7、図8に示す例について述べる。本例の場合、ボイラー1は下部の水を溜める貯留室5と、貯留室5の上部のスチーム室8と、ヒータ6を有する沸騰室7とで構成されている。そして沸騰室7側と、貯留室5やスチーム室8側とを分離してある。貯留室5の下部と沸騰室7の下部とを連通穴23にて連通させてあり、沸騰室7の上部とスチーム室8の上部とを噴出口24にて連通させてある。このように構成されていると、貯留室5の水が連通穴23を介して沸騰室7に供給され、水が沸騰することでスチームが発生し、このスチームが噴出口24からスチーム室8に噴出され、スチーム室8からスチーム流路3に供給される。このようにすることにより徐々に水を沸騰させることができてスチームの発生時間を速めることができる。
【0026】
また排水口17とボイラー1の貯留室5との間にフィルター25を設けてある。本例の場合、貯留室5と結露復水管4とを連通させる開口26にフィルター25を配置してある。このようにしてあると、水に含まれたカルシウムイオンが固体化したカルシウムとなって析出しても、ボイラー1内の水を排水するときにフィルター25にて捕集され、析出したカルシウムが排水弁15に挟まることがなくなり、排水弁15の閉状態で排水弁15から水漏れするおそれがなくなる。
【0027】
また本例の場合、ボイラー1の貯留室5の底面には連通穴23を上端とし、開口26を下端とする勾配28を設けてある。このように勾配28を設けると、ボイラー1の貯留室5の水を抜くとき勾配28にて水が残らないようにスムーズに抜くことでき、ボイラー1内を乾燥する際に発生する固形カルシウムを低減させて排水弁15が詰まるのを防止できると共に使用者の水抜き作業を緩和することができる。
【0028】
図7に示す例ではスチーム室8のスチームが図7の矢印のように入口13を介してスチーム流路3に入るためにスチームの勢いで結露がスチーム流路3に入るおそれがあるが、図1、図2、図3,図4、図6、図8の例ように入口13の口縁から下方に垂下壁29を突設してあると、図8の矢印のように垂下壁29を迂回するようにスチームが入口13を介してスチーム流路3に入り、スチーム室8から結露がスチーム流路3に入り込むおそれが少なくなる。
【0029】
【発明の効果】
本発明は叙述の如くノズルをスチーム流路の前記結露復水管の垂直な上部縦管路部を兼ねる部分の下部に配置したので、結露を伴ったスチームの流れをノズルに到達する前に鉛直下方にして、結露が下方に存在する水に滴下させやすくでき、結露がノズルに到達するのを防ぐことができてノズルから結露が吐出するのを防止できるものである、また前記結露復水管の垂直な上部縦管路部を兼ねる部分の下部のノズルへ接続する位置よりも高い位置にスチームをイオン化させる放電極を配置すると、放電極を従来の結露の溜まりやすい横方向のスチーム流路から垂直部分に配置を変えることにより、放電極下に結露が溜まって放電極と結露とが触れることを防ぐことができ、スチームをイオン化するものにおいては安定してスチームがイオン化できる。
【0030】
また、結露復水管の下部縦管路部と横管路部との間の部分からボイラー内の水を外部に排水する排水管を連出し、ボイラー下部の結露復水管の横管路部と連通させる開口にフィルターを設けると、カルシウムが析出してもフィルターで捕集して排水口の弁が詰まるのを防止できる。
【0031】
またボイラー内の水を貯留する貯留室の底面に結露復水管の横管路部とを連通させる開口を設け、この貯留室の底面に上記開口を下端とする勾配を設けると、ボイラー底面の水を勾配にて水が残らないようにスムーズに排水でき、ボイラー内を乾燥する際に発生する固形カルシウムを低減させて排水口の弁が詰まるのを防止できると共に使用者の水抜き作業を緩和することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a steam generator such as a steam-type beauty device, facial device, and inhaler.
[0002]
[Prior art]
In general, steam-type beauty instruments, facial instruments, inhalers, and other appliances cause steam generated by a boiler to be ejected from a nozzle to a human body through a steam flow path. Otherwise, there is a risk of burns, and for this reason, the appliances for the above applications must be designed to prevent the ejection of condensed water droplets (the patent application previously filed by the applicant of the present patent application as preventing the ejection of condensed water droplets). (Kaihei 11-4869).
[0003]
Conventionally, there has been a condensate condensate pipe provided to condense the boiler in order to prevent the condensation water droplets from being ejected, and these have a structure as shown in FIG. A steam flow path c is extended from the upper part of the steam chamber b of the boiler a having a built-in heater, and the steam flow path c has a nozzle d for ejecting steam and the steam flow path c in order to condense dew condensation generated in the steam flow path c. A dew condensation condensate pipe e connected to the lower part of the boiler a is provided, and the nozzle d is arranged at the tip of a pipe line protruding from the upper part of the pipe connecting the steam flow path c and the dew condensation condensate pipe e.
[0004]
There are also steam generators that have the ability to ionize steam. As an example of the structure, a discharge electrode f is provided in the steam flow path c for sending steam from the boiler a, and a high voltage is generated between the discharge electrodes f by a high voltage generator provided outside the steam generator. It is structured to ionize the steam that passes through. Conventionally, the discharge electrode f has been provided in the pipe line c1 in the lateral direction of the steam passage c.
[0005]
There is also an instrument that has the function of draining residual water inside the boiler after the instrument is used. As a structural example, a drain outlet is provided in the condensation condensate pipe, and a valve that can be opened and closed is provided between the drain outlet and the condensation condensate pipe.
[0006]
[Problems to be solved by the invention]
By the way, in the above conventional structure, the steam generated from the steam chamber b reaches the nozzle d through the horizontal line c1 and the upward line c2. Condensation generated between the steam chamber b and the nozzle d is carried in the direction of the nozzle d along with the steam force, and the steam channel c is composed of upper and lateral pipes c1 and c2. There is a problem that condensation easily reaches the nozzle d.
[0007]
Further, in the steam generator having a function of ionizing steam, the discharge electrode f for ionization is provided in the pipe c1 in the horizontal direction of the steam channel c, so that the dew condensation generated in the pipe c1 is a tube. Since it is easy to deposit on the path c1, condensation is likely to adhere to the discharge electrode f, and when condensation is attached to the discharge electrode f, it becomes difficult to discharge and ionization of steam becomes impossible.
[0008]
Also, when water is boiled by the boiler heater, calcium ions contained in the water become solidified calcium and precipitate in the boiler, but in the appliance with the function of draining the residual water inside the boiler, When the precipitated calcium is drained as described above, it may be caught by the valve, and water leakage may occur from the valve when the valve is closed.
[0009]
The present invention has been made in view of the description, and it is difficult for condensation to protrude from the nozzle, and in the case of ionizing steam, the steam can be stably ionized, and in the case of having a drainage function, the valve It is an object to provide a steam generating device that does not cause water leakage.
[0010]
[Means for Solving the Problems]
In order to solve the above problems, the steam generator of the present invention has a storage chamber for storing water in a lower part of a boiler that heats and vaporizes water, and steam that jets steam generated in a boiling chamber provided in the boiler A nozzle is provided in the upper part of the storage chamber to eject steam generated in the boiler, a steam channel for supplying steam from the steam chamber of the boiler to the nozzle, and condensed water condensed on the nozzle and the steam channel In order to condense the water into the storage chamber of the boiler, it is composed of a vertical part and a horizontal pipe part composed of an upper vertical pipe part, a throttle pipe part and a lower vertical pipe part, and the upper vertical pipe part is provided the condensation condensate water pipe which also serves as a steam channel, characterized in that a nozzle so as to communicate the lower the dew parts fraction Ru serves as a vertical upper vertical pipe portion of the condensate water tube steam flow path. By arranging the nozzle in the middle of the vertical part of the condensate condensate pipe, the steam flow with condensation can be lowered vertically before reaching the nozzle, so that the condensation can be easily dripped into the water present below. Reaching the nozzle can be prevented.
[0011]
It is also preferable that the steam flow path between the condensing condensate pipe and the boiler has an inverted U-shaped U-shaped pipe that protrudes upward in the boiler. Condensation generated in the steam channel cannot go to the nozzle because it cannot go to the nozzle unless it gets over the U-shaped pipe. Further, since the flow of steam is passed through the U-shaped pipeline, the flow is rectified downward, so that dew condensation beyond the apex of the U-shaped pipeline does not easily reach the nozzle side.
[0012]
Further, it is also preferable that a discharge electrode for ionizing steam is arranged at a position higher than a position connected to a nozzle at a lower portion of a portion of the steam flow path that also serves as a vertical upper vertical pipe portion of the condensation condenser. . By changing the arrangement of the discharge electrode from the conventional steam flow path in which condensation is likely to accumulate to the vertical portion, it is possible to prevent condensation from accumulating under the discharge electrode and touching the discharge electrode with condensation.
[0013]
It is also preferable that a water absorbing body is provided in the steam flow path between the dew condensation condensate pipe and the boiler. If dew condensation is accumulated on the boiler side below the top of the U-shaped pipe line, if a large amount of dew condensation is accumulated, the surface of the dew will wave between the lower end of the U-shaped line and the apex due to the force of steam. Cracks may be generated, causing squealing noise and reducing the amount of steam generated by blocking the steam flow path. However, as described above, water is absorbed into the steam flow path on the boiler side below the top of the U-shaped pipe line. By providing a body, the generated condensation can be easily condensed in the boiler, and a large amount of condensation can be prevented from accumulating in the steam channel.
[0014]
Further, in the inverted U-shaped U-shaped pipe line, it is also preferable that a small-diameter portion is provided in the pipe line on the boiler side below the apex of the U-shaped pipe line. If dew condensation is accumulated on the boiler side below the top of the U-shaped pipe line, if a large amount of dew condensation is accumulated, the surface of the dew will wave between the lower end of the U-shaped line and the apex due to the force of steam. Cracks and generates a bumpy sound, and the steam generation amount may be reduced by blocking the steam flow path. However, as described above, the small diameter is formed at the bottom of the U-shaped pipe line and at the boiler side pipe line. By providing a part, it is possible to increase the steam flow velocity at the position where the membrane is stretched, and to send unstable condensation that seems to exceed the U-shaped pipe line to the condensation condensate pipe at a high speed. Accumulation of condensation can be prevented.
