Description

【０００１】
【発明の属する技術分野】
本発明は、浴室内で加湿、昇温することで従来の浴室をサウナとして使用するための浴室サウナ装置に関する。
【０００２】
【従来の技術】
従来、この種の浴室サウナ装置は浴室側壁内部に設置され、ボイラーなどの熱源を利用して加湿、加熱を行うものが知られている（例えば、特許文献１参照）。
【０００３】
以下、その浴室サウナ装置について図を参照しながら説明する。
【０００４】
図１２に示すように、図中１０１はスチームサウナ装置を構成するスチームサウナユニット本体で、このスチームサウナ本体１０１は浴室を形成するユニットバスルーム１０２のカウンタ部１０３内に設置されている。
【０００５】
前記スチームサウナユニット本体１０１は図１３及び図１４に示すように、外装体１０４を備え、この外装体１０４の前面中央部には、外部から空気Ａを吸入する空気吸入口１０５が、また、その下部にはスチーム吹出口１０６がそれぞれ開口されていると共に、このスチーム吹出口１０６には蒸気Ｓの噴出し方向を調整する風向調整板が設けられている。
【０００６】
さらに、前記外装体１０４の内部には噴出湯管１０７が上部位置に配置され、この噴出湯管１０７の下部には、熱交換促進部材１０８が配置されていると共に、この熱交換促進部材１０８の下部背面にはモータ駆動のファンユニット１０９が配置されている。
【０００７】
前記熱交換促進部材１０８は、上部１０８ａが前記外装体１０４の後方に位置するように傾斜し、かつ、その外装体１０４内の前方に位置する下部１０４ｂの背面側に前記ファンユニット１０９を配置している。
【０００８】
また、前記外装体１０４の下部で熱交換促進部材１０８の下方には排湯を受けるドレンパン１１０が設置され、ドレンパン１１０には内部にたまった排湯を排水するための排水口１１１が設けられている。
【０００９】
熱交換促進部材１０８はフィンチューブ式の熱交換器であり、配管内にボイラーなどの熱源から供給される高温の温水を流通させる事で外部を流通する流体と熱交換を行い加熱する。
【００１０】
噴出湯管１０７には複数の湯噴出口１１２が設けられており、給湯配管（図示せず）に接続される給湯口１１３から定流量弁１１４及び電磁弁１１５を介して噴出湯管１０７に温水を供給されることで湯噴出口１１２から熱交換促進部材１０８の上部に放散させ、熱交換促進部材１０８に流下した温水の一部が熱交換促進部材１０８内を流れる高温の温水と熱交換を行う事で蒸発し、この蒸発によって発生する蒸気Ｓをファンユニット１０９によってスチーム吹出口１０６から吹出す。吹出されたスチームが浴室１０２に満たされることによって浴室内をミストサウナとして利用する事が出来るようになる。

【００１３】
本発明はこのような従来の課題を解決するものであり、比較的コンパクトで、設置可能な浴室を限定せず、多くの加湿量が得られる加湿部を搭載した浴室サウナ装置を提供する事を目的としている。

【００１５】
本発明は、このような従来の課題を解決するものであり、温水を無駄に廃棄することなく、効率の良い加湿を行う事が可能な加湿部を搭載した浴室サウナ装置を提供する事を目的している。

【００７２】
以下、本発明の実施例について図面を参照しながら説明する。
【００７３】
【実施例】
（実施例１）
図１に示すように、浴室１０２の天井裏部に設置するサウナ本体１０１は、図２に示すように、外装体１０４に浴室内の空気をサウナ本体に導入するための空気吸入口１０５及び、浴室１０２内の空気を吸入し加湿部へと送り、高温多湿になった空気を浴室内に送風するための送風機１０９、送風機１０９により浴室内から送られてきた空気を加湿するための加湿部１、加湿部により高温高湿になった空気を浴室１０２内に排出するための吹出し口１０６、加湿部に温水を循環させるための加湿水循環経路２、加湿水循環経路２内の温水を循環させるためのポンプ３、加湿水循環系路２上で加湿水を貯留するためのタンク４、熱源からの温水と加湿水循環経路２内を流れる加湿水を熱交換するための熱交換器５、タンク４に水を供給するための給水口６を備えている。
【００７４】
送風機１０９により浴室内から空気吸入口１０５を通ってサウナ本体に導入された空気は加湿部１に送られ、加湿部１内部で高温高湿の状態となった後、吹出し口１０６を通って浴室１０２に排出される。
【００７５】
加湿部１は図３に示すように、透湿性を有する多孔性材料を管状に形成した中空糸７を複数束ね、略円筒形状のケーシング８内に収納し、その両端部において、中空糸７の内側と外側が連通しないように複数の中空糸７の間をエポキシなどの樹脂９により封止してある。ケーシング８には中空糸７の内側の流路に空気を供給するための空気導入部１０、中空糸７内部の流路から空気を排出するための空気排出部１１、中空糸７の外側でケーシング８の内側に温水を供給するための温水導入部１２、中空糸７の外側でケーシング８の内側を流通してきた温水を加湿部１の外部へと排出するための温水排出部１３が設けられている。
【００７６】
加湿水循環経路２上のタンク４からポンプ３により送水された加湿用の水は加湿水循環経路２に接続された熱交換器５により熱源から送られてくる高温の温水と熱交換を行い、高温になった後、加湿部１の温水導入部１１より加湿部１内の中空糸７の外側、ケーシング８の内側の流路へと供給される。高温の加湿水は加湿部１内で透湿性をもつ中空糸７の内側の流路を通る空気と熱交換及び水蒸気の移行を行って低温となった後、温水排出部１３を経て温水排出部１３に接続された加湿水循環経路２へと排出される。加湿水循環経路２に排出された加湿後の温水は再びタンク４へと戻される。
【００７７】
タンク４内に貯留された加湿水は加湿部１で空気に供給され徐々に水量が減少する。このため、タンク４内には水位センサー１４を設け、タンク４内の加湿水の水量が一定以下の量となった場合に給水口６より市水を供給し、タンク４内の加湿水が無くならないようにしている。
【００７８】
上記のような構成を取る事により、熱源で高温にされた温水を熱交換器５に循環させる事により加湿水循環経路２内の加湿水を昇温し、高温となった加湿水を加湿部１に供給する事で加湿部１に供給される浴室１０２内の空気を加熱および加湿し、高温高湿となった空気を吹出し口１０６から浴室１０２内へと排出することで浴室１０２内の雰囲気を高温高湿なミストサウナ状態にすることが可能となる。
【００７９】
また、従来の方式のミストサウナ装置では、加湿に使用されなかった加湿水は加湿部１に設けられたドレンパンにより装置外部に排出されるため熱交換器５により昇温された温水が無駄に外部に廃棄されていたが、本発明における加湿部１では加湿に使用されなかった加湿水は再び加湿水循環経路２により熱交換器５へと送られ、再び高温となった状態で加湿部１に戻されるため、熱源から供給される熱を無駄に廃棄することが無く、従来の方式に比べ効率よく加湿を行う事が可能となる。
【００８０】
また、加湿部１に中空糸７を用いる事で比較的コンパクトなサイズの加湿部１でありながら、空気と温水の熱交換面積を大きく取る事が可能となり、比較的大容量な加熱及び加湿を行う事が可能となる。
【００８１】
さらに、本実施例のように、送風機の吹出し側に中空糸を用いた加湿部を設置する事で、送風機の吹出し側で生じる風切音などの騒音を中空糸部で吸収し、サウナ装置の吹出し部における騒音を低減する効果がある。
【００８２】
なお、本実施例において、中空糸とケーシングを封止するための樹脂としてエポキシ系材料を用いたが、中空糸の内側の流路と中空糸の外側の流路を連通しないように封止出来れば良く、ウレタンやシリコンなどの樹脂を用いてもその作用効果に差異を生じず、なお望ましくは高温の温水にさらされた雰囲気でも封止部が中空糸及びケーシングから脱落しないものが好ましい。
【００８３】
また、本実施例では透湿性を有する中空糸の材料を透湿性を有する多孔性材料として特に指定しなかったが、高分子電解質膜のように非多孔性で空気を透過せずに、水蒸気のみを選択的に透過する性質を有する材料であれば良く、その作用効果に差異を生じず、なお好ましくは、液体の温水が透過しない材料である事が望ましい。
【００８４】
また、本実施例においては中空糸の内側の流路に空気を、中空糸の外側でケーシングの内側の流路に温水を流通させる構成としたが、逆に中空糸の内側の流路に温水を、中空糸の外側でケーシングの内側の流路に加湿用の温水を流通させる構成としても良く、その作用効果に差異を生じず、なお好ましくは、それぞれの流路を流通する空気及び加湿用の温水の加湿部における圧力損失が極力小さくなる事が望ましく、このために中空糸の内外径及びケーシング内に収納する本数、ケーシングの内径などを内部を流通する空気及び温水の流量に合わせて最適化する事が望ましい。
【００８５】
（実施例２）
以下、本発明の実施例２について図を参照しながら詳細に説明する。なお、本実施例において、実施例１と同等の作用をもつものについては同一の符号を付し、その詳細な説明を省略する。

図４に示すのは本実施例における加湿部１の概略図である。図４に示すように、本実施例におけるケーシング８はその両端部８ａ、８ｃの内外径が中心部８ｂの内外径に比べ若干大きくなっている。このため、両端部８ａ、８ｃにおいては中空糸７とケーシング８の間に温水が流通することのできる空間１５が存在する。ケーシング８の両端部外側には温水をケーシング８内に導入するための温水導入部１２及び１３がケーシング８と一体に構成されており、温水導入部１２及び温水排出部１３はケーシングの外側の接線方向に円筒形の接続管を設け、接続管内に温水を流通させるための温水通路１６を設ける事で構成されている。
【００８７】
温水導入部１２の温水導入方向前方には温水の流通方向を変更させるための流通方向変更板１７が設けられており、温水導入部１２内の温水通路１６を流通してきた温水は流通方向変更板１７によりケーシング８の周方向に向きを変え、ケーシング８内を旋回しながら他端の温水排出部１３方向へと流通する。この際、空気導入部１０と温水導入部１２は加湿部１つまりケーシング８の他端に位置するようにし、同様に空気排出部１１と温水排出部１３も加湿部１つまりケーシング８の他端に位置するようにする事で空気と温水の流通方向を略対向する方向とする事ができ、加湿部１における空気と温水の熱交換を効率良く行う事が可能となる。
【００８８】
上記のような構成を取る事で従来、ケーシングとは別に設けられていた温水導入部及び温水排出部をケーシングと一体的に設ける事が可能となり、接合部における温水の漏れを防止できると共に、略円筒形状のケーシングを用い、その接線方向に温水を流入させる事により温水がケーシング内を充分に旋回して流通するため、温水がケーシング内全体に行き渡り、温水がケーシング内の一部に偏って流通する事による加湿面積の低下に伴う加湿量の低下を防止する事が可能となる。
【００８９】
また、流通方向変更板を設けることで、温水導入部から進入した温水が直接中空糸に激突する事に伴う中空糸の変形を防止する事が可能となり、中空糸の内側の流路を閉塞させる問題を解消できると共に、導入された温水をケーシング内全体に旋回させることが可能となるため、加湿部における加湿効率を向上させる事が可能となる。
【００９０】
なお、本実施例においては流通方向変更板は温水導入部のみに設けたが、温水排出部に同様に設けても良く、その作用効果に差異を生じない。
【００９１】
（実施例３）
以下、本発明の実施例３について図を参照しながら詳細に説明する。なお、本実施例において、実施例１及び実施例２と同等の作用をもつものについては同一の符号を付し、その詳細な説明を省略する。
【００９２】
図５に示すのは、本実施例における熱交換器５の概略図である。図５に示すように、本実施例における熱交換器５は内外径の異なる２種類の銅管のうち、内外径の大きい銅管（外管１８）の内部に内外径の小さい銅管（内管１９）を挿入したいわゆる２重管をらせん状に配設した構造となっている。このような螺旋形状の２重管を螺旋の径を変えて複数並列に接続し、最大外径の螺旋管（第一螺旋管２０）の内側に螺旋径が若干小さい螺旋径の２重螺旋管（第二螺旋管２１）を配設し、第一螺旋管２０と第二螺旋管２１を並列に接続する事で熱交換器５を構成する。
【００９３】
また、本実施例では特に図示しなかったが、第一螺旋流路２０内を流れる加湿水及び熱源からの高温水と第ニ螺旋流路２１内を流れる加湿水及び熱源からの高温水の流量がほぼ一致するように、少なくともどちらか一方の螺旋流路内に両螺旋流路の圧力損失を一致させるための絞りなどを設ける事が望ましい。
【００９４】
このようにして構成された熱交換器５の内管１９内部に連通するように加湿水循環経路２を接続し、内管１９の外側と外管１８の内部の空間に連通するように熱源からの温水流路を接続する。これにより、内管１９の内部を流れる加湿水と内管１９の外部で外管１８の内部を流れる熱源から供給される高温の温水は内管１９の管壁を介して熱交換を行い、加湿水循環経路２内を流れる加湿水を昇温する。このとき、加湿水循環経路２内を流れる温水と熱源から供給される高温水の熱交換器内部における流通方向を対抗する方向とする。これにより、熱交換器５における加湿水と熱源からの高温水の熱交換の効率を向上させる事が出来る。
【００９５】
このような構成を取る事で、比較的コンパクトな容量で大きな熱交換面積をもつ熱交換器を得る事ができ、熱源からの熱を効率良く加湿部へと伝達する事が可能になり、加湿部における加湿量を増加させる事が出来ると共に、加湿の効率を向上させる事が可能となる。
【００９６】
なお、本実施例においては内管の内側に加湿水を、内管の外側で外管の内側にあたる流路に熱源からの高温水を流通させる構成としたが、逆に内管の内側に熱源からの高温水を、内管の外側で外管の内側にあたる流路に加湿水を流通させた場合でもその作用効果に差異を生じず、なお好ましくは、熱源から供給される熱が熱交換器において大気中に放出されてしまうのを極力防ぐ構造が望ましい。
【００９７】
また、本実施例では特に図示しなかったが、第一螺旋流路内を流れる加湿水及び熱源からの高温水と第ニ螺旋流路内を流れる加湿水及び熱源からの高温水の流量がほぼ一致するように少なくともどちらか一方の螺旋流路内に両螺旋流路の圧力損失を一致させるための絞りなどを設ける事が望ましい。
【００９８】
また、本実施例では２重管を正螺旋状に配設したが、楕円状の螺旋形状に配設しても良く、その作用効果に差異を生じない。
【００９９】
（実施例４）

図６に示すのは、本実施例におけるホームサウナの概略図である。図６に示すように、本実施例の熱交換器５は加湿水循環系路２上のタンク４内部に設けられている。
【０１０１】
図７に示すように、熱交換器５の内管１９の内部にタンク内の加湿水を導入するように接続し、内管１９の外側で外管１８の内側にあたる流路に熱源からの高温水を接続する。このとき、加湿水と熱源からの高温水の流通方向が対向する方向となるように接続する。さらに加湿部１で熱交換及び加湿を行い低温となり加湿水循環経路２を流通してきた加湿水はタンク４の温水戻り口２２に接続されるが、このとき、温水戻り口２２は内管１９の外部で外管１８の内部を流通する熱源からの高温水の出口側に設けられ、タンク内の加湿水が熱源からの高温水の流通方向と概略対向する方向に流通するようにする。
【０１０２】
このような構成を取る事により、内管１９の管壁を介して加湿水と熱源からの高温水が熱交換を行うと共に、外管の管壁を介しても熱交換を行う事になり、外管の管壁を介して加湿水の予備加熱を行った後、内管の管壁を介して更なる昇温を行う事で加湿水をより高温な状態にする事が可能となる。さらに、外管の管壁外部に加湿水を充填する事で、熱交換器５から大気中に熱を放出してしまう事に伴う熱ロスを最小限に抑える事が可能となり、更なる熱交換効率の向上を図ることが出来る。
【０１０３】
（実施例５）
以下、本発明の実施例５について図を参照しながら詳細に説明する。なお、本実施例において、実施例１、実施例２、実施例３及び実施例４と同等の作用をもつものについては同一の符号を付し、その詳細な説明を省略する。

【０１０５】
図９は加湿部１、タンク４及び熱交換器５の概略図である。図９に示すように、中空糸７はタンク４内に設けられ、中空糸７内部を流通する空気は中空糸７外部でタンク４内部に貯留されている加湿用温水と熱交換を行い、加湿昇温される。
【０１０６】
同様に熱交換器５もタンク４内に設置され、タンク４外に設けられたポンプ３によりタンク４内の加湿用温水は熱交換器５の内管１９内部へと送られる。熱交換器５の内管１９の外部で外管１８の内部の流路を流通する熱源からの高温水と熱交換器内部で熱交換を行う事で昇温した加湿用温水は熱交換器５外部のタンク４内へと排出され、タンク４内に設置された加湿部１を流通する空気と熱交換を行う。
【０１０７】
上記のような構成を取る事により、熱交換器外部に加湿水を貯留する事で熱交換器から大気に熱を放出してしまう事による熱ロスを最小限に抑える事が可能となる。さらに、熱交換器から加湿部に至る加湿水循環経路を省略する事が出来るため、加湿水循環系炉における熱ロスをなくす事が可能となり更に熱効率を向上させることができる。
【０１０８】
（実施例６）
以下、本発明の実施例６について図を参照しながら詳細に説明する。なお、本実施例において、実施例１、実施例２、実施例３、実施例４及び実施例５と同等の作用をもつものについては同一の符号を付し、その詳細な説明を省略する。
【０１０９】
図１０に示すのは、本実施例における熱交換器５の概略図である。図１０に示すように、本実施例の熱交換器５は内管１９を直列に接続し、外管１８を２段で並列に設けた２重管構造となっている。内管１９の内部には加湿水循環系路２を接続することで加湿水を流通させ、内管１９の外部で外管１８の内部の流路には熱源からの高温水を流通させる。この際、前述したように、熱源からの高温水は２段構成とし、それぞれの入口を熱源と接続し、それぞれ異なる流量の高温水を流通させる。
【０１１０】
上記のような構成を取る事により、熱交換器第一段部で一定の温度まで昇温された加湿水は第二段部でさらに加熱されることになる。この際、第一段部と第二段部における高温水の流通状態を変更する事でそれぞれの温度帯における最も効率の高い状態で熱交換を行う事が可能となり、熱源からの熱を効率良く加湿水に熱交換させることが可能となり、加湿部に供給する加湿水の温度をより高温にする事が出来るため加湿における加湿量を増加させ、より効率の高い加湿を行う事が可能となる。
【０１１１】
なお、本実施例では内管内部の流路に加湿水を、内管の外部で外管の内部の流路に熱源からの高温水を流通させるようにしたが、逆に内管の内部に熱源からの高温水を、内管の外部で外管の内部の流路に加湿水を流通させる構成としても良く、その作用効果に差異を生じない。ただし、この場合は内管内部の流路を２段構成とし、内管外部で外管の内部の流路を直列に接続する構成とする必要が生じる。
【０１１２】
（実施例７）

図１１に示すのは、本実施例におけるホームサウナ装置の浴室取りつけ時の外観図である。図に示すように、ホームサウナ装置１０１において、浴室内の空気をホームサウナ装置１０１に吸込む吸込み口１０５とホームサウナ装置１０１内部で加湿昇温された空気を吹き出す吹き出し口１０６はホームサウナ装置１０１の最も離れた位置に設けられている。さらに吹き出し口１０６には吹き出し口から吹き出される高温高湿の空気の流通方向を変更するためのルーバー２３が設けられており、このルーバー２３により、吹き出し口１０６から吹き出される高温高湿の空気は吸込み口１０５の方向とは逆方向へと吹き出されるようにその流通方向を変更される。

[0072]
Embodiments of the present invention will be described below with reference to the drawings.
[0073]
【Example】
(Example 1)
As shown in FIG. 1, the sauna body 101 installed in the ceiling back part of the bathroom 102 is, as shown in FIG. 2, an air inlet 105 for introducing the air in the bathroom to the exterior body 104 into the sauna body, and The air in the bathroom 102 is inhaled and sent to the humidifying unit, and the humidifier 1 for humidifying the air sent from the inside of the bathroom by the blower 109 to blow the hot and humid air into the bathroom. The air outlet 106 for exhausting the air that has become hot and humid by the humidifying part into the bathroom 102, the humidifying water circulation path 2 for circulating hot water in the humidifying part, and the hot water in the humidifying water circulating path 2 for circulating Pump 3, tank 4 for storing the humidified water on the humidified water circulation path 2, heat exchanger 5 for exchanging heat between the hot water from the heat source and the humidified water flowing in the humidified water circulating path 2, and water in the tank 4 To supply It is equipped with a water supply port 6.
[0074]
The air introduced into the sauna body from the bathroom through the air suction port 105 by the blower 109 is sent to the humidifying unit 1, becomes hot and humid inside the humidifying unit 1, and then passes through the outlet 106 to the bathroom. 102 is discharged.
[0075]
As shown in FIG. 3, the humidifying unit 1 bundles a plurality of hollow fibers 7 in which a porous material having moisture permeability is formed into a tubular shape, and accommodates the hollow fibers 7 in a substantially cylindrical casing 8. A plurality of hollow fibers 7 are sealed with a resin 9 such as epoxy so that the inner side and the outer side do not communicate with each other. The casing 8 includes an air introduction part 10 for supplying air to the flow path inside the hollow fiber 7, an air discharge part 11 for discharging air from the flow path inside the hollow fiber 7, and a casing outside the hollow fiber 7. A hot water introduction part 12 for supplying warm water to the inside of the hot water 8 and a warm water discharge part 13 for discharging the warm water flowing through the inside of the casing 8 outside the hollow fiber 7 to the outside of the humidifying part 1 are provided. Yes.
[0076]
The water for humidification sent from the tank 4 on the humidification water circulation path 2 by the pump 3 exchanges heat with the high-temperature hot water sent from the heat source by the heat exchanger 5 connected to the humidification water circulation path 2 to increase the temperature. After that, the hot water introduction part 11 of the humidification part 1 is supplied to the flow path inside the hollow fiber 7 inside the humidification part 1 and inside the casing 8. The high-temperature humidified water is subjected to heat exchange and steam transfer with air passing through the flow path inside the hollow fiber 7 having moisture permeability in the humidifying section 1 and then becomes a low temperature, and then passes through the warm water discharging section 13 to the warm water discharging section. 13 is discharged to the humidified water circulation path 2 connected to 13. The humidified hot water discharged to the humidified water circulation path 2 is returned to the tank 4 again.
[0077]
The humidified water stored in the tank 4 is supplied to the air in the humidifying unit 1 and the amount of water gradually decreases. For this reason, a water level sensor 14 is provided in the tank 4, and when the amount of humidified water in the tank 4 falls below a certain level, city water is supplied from the water supply port 6, and there is no humidified water in the tank 4. I try not to be.
[0078]
By taking the configuration as described above, the temperature of the humidified water in the humidified water circulation path 2 is increased by circulating hot water heated to a high temperature by the heat source 5 to the humidified portion 1. The air in the bathroom 102 supplied to the humidifying unit 1 is heated and humidified, and the atmosphere in the bathroom 102 is exhausted from the outlet 106 into the bathroom 102 by heating and humidifying the air. A high temperature and high humidity mist sauna can be achieved.
[0079]
Further, in the conventional type mist sauna apparatus, the humidified water that has not been used for humidification is discharged outside the apparatus by the drain pan provided in the humidifying section 1, so that the warm water heated by the heat exchanger 5 is wasted. However, the humidified water that has not been used for humidification in the humidifying unit 1 of the present invention is sent again to the heat exchanger 5 through the humidifying water circulation path 2 and returned to the humidifying unit 1 in a state where the temperature becomes high again. Therefore, heat supplied from the heat source is not wasted, and humidification can be performed more efficiently than in the conventional method.
[0080]
In addition, by using the hollow fiber 7 for the humidifying unit 1, it is possible to increase the heat exchange area of air and hot water while the humidifying unit 1 has a relatively compact size, and relatively large capacity heating and humidification can be achieved. Can be done.
[0081]
Furthermore, as in this embodiment, by installing a humidifying unit using hollow fibers on the blowout side of the blower, noise such as wind noise generated on the blowout side of the blower is absorbed by the hollow fiber portion, and the sauna device There is an effect of reducing noise in the blowout part.
[0082]
In this example, an epoxy-based material was used as the resin for sealing the hollow fiber and the casing, but the resin can be sealed so that the flow path inside the hollow fiber and the flow path outside the hollow fiber do not communicate with each other. Even if a resin such as urethane or silicone is used, it is preferable that the effect does not differ even when the resin is used, and that the sealing portion is preferably not dropped from the hollow fiber and the casing even in an atmosphere exposed to high-temperature hot water.
[0083]
Further, in this example, the hollow fiber material having moisture permeability was not specifically designated as the porous material having moisture permeability, but it was not porous like the polymer electrolyte membrane and did not transmit air, but only water vapor. Any material may be used as long as it has a property of selectively permeating, and it is desirable that the material does not cause a difference in its operation and effect and does not allow liquid warm water to permeate.
[0084]
In this embodiment, air is flown through the flow path inside the hollow fiber, and hot water is circulated through the flow path inside the casing outside the hollow fiber. The warm water for humidification may be circulated in the flow path inside the casing outside the hollow fiber, and there is no difference in the function and effect. Preferably, the air circulates in each flow path and for humidification. It is desirable that the pressure loss in the humidifying part of the hot water is as small as possible. For this reason, the inner and outer diameters of the hollow fibers, the number of the hollow fibers to be accommodated in the casing, the inner diameter of the casing, etc. are optimally matched to the flow of air and hot water flowing inside It is desirable to make it.
[0085]
(Example 2)
Hereinafter, Example 2 of the present invention will be described in detail with reference to the drawings. In the present embodiment, components having the same functions as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
[0086]
FIG. 4 is a schematic diagram of the humidifying unit 1 in the present embodiment. As shown in FIG. 4, in the casing 8 in this embodiment, the inner and outer diameters of both end portions 8a and 8c are slightly larger than the inner and outer diameters of the center portion 8b. For this reason, in both end portions 8 a and 8 c, there is a space 15 in which warm water can flow between the hollow fiber 7 and the casing 8. Hot water introduction parts 12 and 13 for introducing hot water into the casing 8 are formed integrally with the casing 8 outside both ends of the casing 8, and the hot water introduction part 12 and the hot water discharge part 13 are tangents outside the casing. A cylindrical connecting pipe is provided in the direction, and a hot water passage 16 for circulating hot water is provided in the connecting pipe.
[0087]
A flow direction change plate 17 for changing the flow direction of the hot water is provided in front of the hot water introduction portion 12 in the hot water introduction direction, and the hot water flowing through the hot water passage 16 in the hot water introduction portion 12 is a flow direction change plate. The direction is changed to the circumferential direction of the casing 8 by 17, and it circulates in the direction of the hot water discharge portion 13 at the other end while turning inside the casing 8. At this time, the air introduction part 10 and the hot water introduction part 12 are located at the other end of the humidification part 1, that is, the casing 8. Similarly, the air discharge part 11 and the warm water discharge part 13 are also located at the other end of the humidification part 1, that is, the casing 8. By being positioned, the flow direction of the air and the hot water can be made substantially opposite to each other, and the heat exchange of the air and the hot water in the humidifying unit 1 can be performed efficiently.
[0088]
By adopting the above configuration, it is possible to provide a hot water introduction part and a hot water discharge part, which are conventionally provided separately from the casing, integrally with the casing, and prevent leakage of hot water at the joint part. By using a cylindrical casing and flowing warm water in the tangential direction, the warm water sufficiently swirls and circulates in the casing, so the warm water spreads throughout the casing and the warm water is distributed in a part of the casing. It is possible to prevent a decrease in the amount of humidification due to a decrease in the humidified area.
[0089]
Also, by providing a flow direction changing plate, it becomes possible to prevent deformation of the hollow fiber due to the hot water entering from the hot water introduction part directly colliding with the hollow fiber, and the flow path inside the hollow fiber is blocked. The problem can be solved, and the introduced hot water can be swirled throughout the casing, so that the humidification efficiency in the humidification section can be improved.
[0090]
In the present embodiment, the flow direction changing plate is provided only in the hot water introduction part, but it may be provided in the hot water discharge part in the same manner, and there is no difference in the effect.

As shown in FIG. 5, the heat exchanger 5 in this embodiment has a copper tube (inner / outer diameter) inside a copper tube (outer tube 18) having a larger inner / outer diameter among two types of copper tubes having different inner / outer diameters. A so-called double pipe into which the pipe 19) is inserted is spirally arranged. A plurality of such spiral-shaped double tubes are connected in parallel by changing the diameter of the spiral, and a double spiral tube having a spiral diameter slightly smaller inside the maximum outer diameter spiral tube (first spiral tube 20). The heat exchanger 5 is configured by arranging the (second spiral tube 21) and connecting the first spiral tube 20 and the second spiral tube 21 in parallel.

It is desirable that at least one of the spiral flow paths be provided with a throttle or the like for matching the pressure loss of both the spiral flow paths so that they substantially match.
[0094]
The humidified water circulation path 2 is connected so as to communicate with the inside of the inner pipe 19 of the heat exchanger 5 configured as described above, and from the heat source so as to communicate with the space inside the outer pipe 18 and inside the outer pipe 18. Connect the hot water flow path. As a result, the humidified water flowing inside the inner tube 19 and the hot water supplied from the heat source flowing outside the inner tube 19 inside the outer tube 18 exchange heat through the tube wall of the inner tube 19, thereby humidifying. The temperature of the humidified water flowing in the water circulation path 2 is increased. At this time, it is set as the direction which opposes the distribution direction inside the heat exchanger of the hot water supplied from the heat source and the warm water which flows in the humidification water circulation path 2. Thereby, the efficiency of the heat exchange of the high temperature water from the humidification water and heat source in the heat exchanger 5 can be improved.
[0095]
By adopting such a configuration, a heat exchanger having a relatively compact capacity and a large heat exchange area can be obtained, and heat from the heat source can be efficiently transmitted to the humidification section. It is possible to increase the amount of humidification in the section and improve the efficiency of humidification.
[0096]
In this embodiment, the humidified water is circulated inside the inner tube, and the high-temperature water from the heat source is circulated through the flow path outside the inner tube and inside the outer tube. Conversely, the heat source is disposed inside the inner tube. Even when the humidified water is circulated in the flow path corresponding to the outside of the inner pipe and the inside of the outer pipe of the high-temperature water from the inner pipe, it is preferable that the heat supplied from the heat source is the heat exchanger. It is desirable to have a structure that prevents release to the atmosphere as much as possible.
[0097]
Although not specifically shown in the present embodiment, the flow rates of the humidified water flowing in the first spiral channel and the high-temperature water from the heat source and the humidified water flowing in the second spiral channel and the high-temperature water from the heat source are almost equal. It is desirable to provide a restriction or the like for matching the pressure loss of both the spiral channels in at least one of the spiral channels so as to match.
[0098]
In this embodiment, the double pipes are arranged in a regular spiral shape. However, they may be arranged in an elliptical spiral shape, and there is no difference in the operational effect.
[0099]

[0100]
FIG. 6 is a schematic diagram of a home sauna in the present embodiment. As shown in FIG. 6, the heat exchanger 5 of the present embodiment is provided inside the tank 4 on the humidified water circulation system 2.
[0101]
As shown in FIG. 7, it connects so that the humidified water in a tank may be introduce | transduced to the inside of the inner tube | pipe 19 of the heat exchanger 5, and the high temperature from a heat source is applied to the flow path which hits the inner side of the outer tube | pipe 18 outside the inner tube 19. Connect the water. At this time, it connects so that humidification water and the distribution direction of the high temperature water from a heat source may become the direction which opposes. Furthermore, the humidified water that has been subjected to heat exchange and humidification in the humidifying unit 1 and has been cooled to flow through the humidified water circulation path 2 is connected to the warm water return port 22 of the tank 4. At this time, the warm water return port 22 is connected to the outside of the inner pipe 19. The humidified water in the tank is circulated in a direction substantially opposite to the flow direction of the high temperature water from the heat source.
[0102]
By taking such a configuration, the humidified water and the high temperature water from the heat source exchange heat through the tube wall of the inner tube 19, and also exchange heat through the tube wall of the outer tube, After preheating the humidified water through the tube wall of the outer tube, the humidified water can be brought to a higher temperature state by further raising the temperature through the tube wall of the inner tube. Furthermore, by filling humidified water outside the tube wall of the outer tube, it is possible to minimize heat loss associated with releasing heat from the heat exchanger 5 into the atmosphere, and further heat exchange Efficiency can be improved.
[0103]

[0105]
FIG. 9 is a schematic diagram of the humidifying unit 1, the tank 4 and the heat exchanger 5. As shown in FIG. 9, the hollow fiber 7 is provided in the tank 4, and the air flowing through the hollow fiber 7 exchanges heat with the humidified hot water stored in the tank 4 outside the hollow fiber 7 to humidify the air. The temperature is raised.
[0106]
Similarly, the heat exchanger 5 is also installed in the tank 4, and the hot water for humidification in the tank 4 is sent into the inner pipe 19 of the heat exchanger 5 by the pump 3 provided outside the tank 4. The high temperature water from the heat source that flows through the flow path inside the outer pipe 18 outside the inner pipe 19 of the heat exchanger 5 and the hot water for humidification heated by exchanging heat inside the heat exchanger are the heat exchanger 5. Heat is exchanged with the air that is discharged into the external tank 4 and flows through the humidifying unit 1 installed in the tank 4.
[0107]
By adopting the configuration as described above, it is possible to minimize heat loss caused by releasing heat from the heat exchanger to the atmosphere by storing humidified water outside the heat exchanger. Furthermore, since the humidification water circulation path from the heat exchanger to the humidification section can be omitted, it is possible to eliminate the heat loss in the humidification water circulation system furnace and further improve the thermal efficiency.
[0108]
(Example 6)
Hereinafter, Example 6 of the present invention will be described in detail with reference to the drawings. In the present embodiment, the same reference numerals are given to components having the same functions as those of the first embodiment, the second embodiment, the third embodiment, the fourth embodiment, and the fifth embodiment, and the detailed description thereof is omitted.

The humidified water circulation system 2 is connected to the inside of the inner tube 19 to circulate the humidified water, and the high temperature water from the heat source is circulated to the flow path inside the outer tube 18 outside the inner tube 19. At this time, as described above, the high-temperature water from the heat source has a two-stage configuration, each inlet is connected to the heat source, and high-temperature water having different flow rates is circulated.
[0110]
By taking the above configuration, the humidified water heated to a certain temperature in the first stage of the heat exchanger is further heated in the second stage. At this time, it is possible to perform heat exchange in the most efficient state in each temperature zone by changing the flow state of the high-temperature water in the first stage part and the second stage part, and efficiently heat from the heat source It is possible to exchange heat with the humidified water, and the temperature of the humidified water supplied to the humidifying section can be made higher, so that the amount of humidification in the humidification can be increased and humidification with higher efficiency can be performed.
[0111]
In this embodiment, humidified water is circulated in the flow path inside the inner pipe, and high-temperature water from the heat source is circulated in the flow path inside the outer pipe outside the inner pipe. It is good also as a structure which distribute | circulates humidified water to the flow path inside an outer pipe | tube with the high temperature water from a heat source outside an inner pipe | tube, and does not produce a difference in the effect. However, in this case, the flow path inside the inner pipe needs to have a two-stage configuration, and the flow path inside the outer pipe needs to be connected in series outside the inner pipe.
[0112]
(Example 7)
Hereinafter, Example 6 of the present invention will be described in detail with reference to the drawings. In the present embodiment, the same reference numerals are given to those having the same functions as those of the first embodiment, the second embodiment, the third embodiment, the fourth embodiment, the fifth embodiment, and the sixth embodiment.
