200528083 (1) 九、發明說明 【發明所屬之技術領域】 本發明.是關於設置在一般家庭的浴槽並使之產生三溫 暖浴用的蒸氣之三溫暖用蒸氣產生裝置，特別是，有關於 用來安裝在空餘的空間爲少的浴槽之肋面的三溫暖用蒸氣 產生裝置之構成元件的設計。 【先前技術】 近年，從美容或維持健康的觀點著眼有三溫暖浴的效 用’提案有即使在一般的家庭之中也能實施三溫暖浴的方 法或機器。 在一般的家庭實施最簡單的三溫暖浴是放流熱水於浴 槽至其半滿程度（坐浴（hip bath ))，覆蓋浴罩到入浴 者的肩部分而入浴。藉此，藉由產生在浴槽內的蒸氣而能 享受三溫暖浴。 可是’在該三溫暖浴方法的情況，到底是簡便的方 法’蒸热的溫度不足’並且也沒有充分地效果。 於是利用浴室整體而形成三溫暖空間，已知提案有如 能三溫暖浴者。例如日本特開平5_3 3 7 1 62號公報（文獻 1 )所示，具備用來使蒸氣產生部產生的蒸氣噴出到浴室 內部的蒸氣噴出部。從蒸氣產生部來的蒸氣一旦供給到蒸 氣噴出部的內部並擴散後，從該蒸氣噴出口部的噴出口排 出到浴室內。 另外’在日本特開200 0- 5 5 3 9 7號公報（文獻2 )，提 200528083 (2) 案有用來以浴室整體作爲三溫暖空間而利用之另外的構 成。根據如此的話，浴室內之例如在浴槽的旁邊設置三溫 暖裝置主體。該三溫暖裝置主體，在其內部，藉由從噴嘴 來的溫水噴射而產生的負壓及藉由具備於噴嘴後方的風扇 而吸進浴室內的空氣，使該空氣與噴嘴噴射的溫水混合。 製作成使被加熱的空氣通過導管而吐出到浴室內，並且將 附著在導管的溫水滴回收到溫水回收水槽積存。該被回收 的水被再度加熱，藉由從噴嘴使之噴射，而構成有循環式 的三溫暖裝置。 而且，在日本特許第3406967號公報（文獻3)，提 案有用來以浴室整體作爲三溫暖空間而利用之又另外的構 成。該文獻3提案的蒸氣產生裝置是具備利用蒸氣產生手 段、使在該蒸氣產生手段使用的溫水循環之循環手段、將 水或溫水供給（補給）到該循環手段的水等供給手段、及 將在蒸氣產生手段產生的蒸氣送風之送風手段。特別是， 水等供給手段，如同文獻3所見，具有水等供給源、及使 之介於電磁閥之間的配管。水等供給源是使用自來水，而 以供給其水本身或預定溫度的溫水之熱水供應器來構成。 以該自來水作爲水源的水或溫水，構成供給（補給）到構 成循環手段的其中一部份的泄水盤。 如上述的文獻1〜3所示，即使在一般家庭，也能利 用浴室形成三溫暖用空間，實施三溫暖浴。 然而，記載於上述文獻1〜3之以往的三溫暖裝置及 蒸氣產生裝置，因爲利用浴室整體而形成三溫暖空間，所 -6- 200528083 (3) 以被指摘有各種的問題。 第1問題是浴室的壁面結露，容易造成所謂發霉等的 產生原因。第2問題是浴室內部整體因爲造成问^31多‘ ’ 三溫暖浴的入浴者因爲容易感到呼吸困難，所以令女性等 的利用者頗爲不滿意。而且，第3問題是因爲供給蒸氣於 浴室整體，所以到成爲適於三溫暖的溫度·濕度的狀態的 等待時間長。與此一起，作爲第4問題是等待時間長的部 份，也被指出有所謂電力能源或水資源的使用量變多。 此等的問題是從以浴室整體作爲三溫暖空間而明顯 化，這個緣故，例如上述坐浴（hip bath )，若能將三溫 暖空間留在浴槽內，如此的問題可抑制或解決。 但是，對於使用現狀的三溫暖裝置或蒸氣產生裝置而 在一般家庭的浴槽內生成三溫暖空間，通常，不得不將如 此的裝置設置在難以確保那麼大的空間之浴室的何處，因 爲裝置的尺寸有過大，另外裝置的形狀有不合，所以非常 難確保其設置場所。假使能設置，其部份，導致產生洗浴 處變狹窄等的不方便很多。 【發明內容】 本發明是有鑒於如此以往的問題而加以開發完成者， 提供能以小型，且具有容易設置在狹窄的空間之形狀，容 易地安裝在使用於一般家庭等的浴槽，能容易地利用以浴 槽作爲三溫暖空間的蒸氣產生裝置來作爲其目的。 爲了達成上述目的’根據本發明的話，具備：在預定 -7- 200528083 (4) 方向具有相對之兩側壁面的水槽、安裝在該水槽的上述兩 側壁面之其中一方的側壁面的下方之預定位置，且將積存 在該水槽的溫水或水加溫的電熱器、連接設置在上述水槽 的另一方的側壁面之下方的預定位置的循環埠與設置在該 側壁面的上方之預定處的噴射噴嘴的流路，介插於該流 路，且使上述水槽內的溫水吸上來並從上述噴射噴嘴向該 水槽內噴射的泵、以及在上述水槽的上部的上述預定方向 之途中位置設置朝向該水槽內部的氣液分離用的分離器。 在上述水槽的上部，形成與該水槽的內部連通之外部空氣 吸引用的吸引口於較上述分離器還在上述噴射噴嘴側的位 置，並且形成與該水槽內部連通的蒸氣吹出用的吹出口於 與夾隔上述分離器的上述吸引口的相反側的位置。 根據本發明的話，因爲利用水槽的下部與上部的功能 而配置了各種構成元件，提供能以小型，且具有容易設置 在狹窄的空間之形狀，容易地安裝在使用於一般家庭等的 浴槽，能容易地利用以浴槽作爲三溫暖空間的蒸氣產生裝 置。 【實施方式】 以下，參照添附圖面，並說明本發明之一實施形態。 而且’在本實施形態，所謂「蒸氣」之用語，未必侷限於 100°C的蒸氣，如在浴槽內例如構成40°C前後的溫度，當 作也包含10(TC以下的蒸氣溫度之槪念而使用。 首先，說明使用本發明的三溫暖用蒸氣產生裝置之浴 -8- 200528083 (5) 槽三溫暖系統的整體構成。 在第1圖，顯示如此的浴槽三溫暖系統之整體構成。 如同圖所示，該浴槽三溫暖系統，作爲一例，在位於設置 在浴室BR的浴槽！ 0之長軸方向的足部位置側的短邊上之 肋面RM (緣部），具備其中一部份從其上面突出且殘餘 的部分能裝拆或一體性地設置在垂下的狀態下之蒸氣產生 裝置1 1 °另外’在位於該蒸氣產生裝置n的稍微上側的 位置之浴室壁面，在將送風口朝向浴槽1 〇側的狀態設置 有涼風裝置1 2。 在浴室B R的頂棚背面，設置有從外部接收商用電源 之供給的電源箱1 3 ’構成從該電源供給有電熱器電力於蒸 氣產生裝置11。而且，在該電源箱13，從設置在浴室內 的壁面之適宜的場所之遙控器1 4接收操作訊號，根據該 操作訊號將操作訊號構成傳送控制訊號到蒸氣產生裝置！】 及涼風裝置1 2。 這個緣故’蒸氣產生裝置1 1，雖然詳述於後，但是由 來自肋面RM突出的部分朝向浴槽1 〇的熱水積存部（浴 槽內部）而形成噴射適溫（例如4 (TC前後）的蒸氣（霧 氣）。這個緣故，利用者，在完成蒸氣產生裝置11之運 作準備的階段下’如第2圖所示，進入浴槽1 〇的內部而 加以浴罩F T且保留從其中一部份伸出臉的姿勢，從遙控 器1 4命令蒸氣產生裝置1 1的運作。藉此，以浴槽〗〇的 熱水積存部作爲三溫暖空間，構成能邊坐在浴槽內邊享受 三溫暖浴（發汗浴）。 -9 - 200528083 (6) 以下，以蒸氣產生裝置1 1的構成及動作作爲中心來 詳細說明該浴槽三溫暖系統。 蒸氣產生裝置Π是如第3圖〜第5圖所示，構成大 致正方體狀的箱體。第3圖是顯示從三溫暖浴的利用者 (浴槽側）所見之圖（以下，稱爲正面圖）。第4圖是顯 示其左側面圖，第5圖是顯示其右側面圖。 該蒸氣產生裝置1 1，具備作爲構成其箱體的構成要 素，作爲構成中心的外殻之功能的防水罩2 0、設置在該防 水罩20的上側之通氣導管2 1、及覆蓋該通氣導管2 1的頂 罩22。 在防水罩20的內側，具備在上側及下側透過段部30a 而分割且一體成形成構成一體之空間的水槽3 0。該水槽 3〇之內，構成較段部30a還下側的水槽部分用來積存溫水 的積存水槽3 1，其上側的水槽部分構成熱交換用的熱交換 水槽32。在段部30a設置有水槽內過濾器34。 而且，積存水槽3 1及熱交換水槽3 2未必限定於如上 述一體地成形者，也可製作成在分別以另外個體來成形後 相互地組裝而形成一體的收納空間，也可製作成在分別以 另外個體來成形後，保持另外個體的樣態設置，並且透過 連通部而連結兩者的水槽空間。 在熱交換水槽3 2的第3圖之左側側壁安裝並形成錐 面，相對於此之右側側壁是直立形成。其中，在錐面壁， 如後述，設置有進行加水於水槽內的加水噴嘴3 5之其中 一方，在直立壁的內側面，設置有如後述以泵來使之循環 -10- 200528083 (7) 並使溫水朝向水槽內噴射的噴射噴嘴3 6。 積存水槽3 1構成大致正方體狀，在其中一方的側壁 (在第3圖的左側壁），設置有用來加熱水槽內之水的電 熱器（鎧裝電熱器（sheathed heaters) ) 37。該電熱器37 以氣密狀態貫通側壁並設置成其加熱部位在水槽內側的位 置且端子部位在水槽外側的位置。位在水槽外側的位置之 電極部形成以電熱器罩38來包覆成氣密。 藉此，電熱器3 7的電極部能以雙重的防水區隔來包 覆成氣密。亦即，防水罩2 0與積存水槽3 1之間構成一次 防水區隔，電熱器罩3 8的內部構成二次防水區隔。藉由 該雙重的防水區隔，而更確實地保護有電熱器3 7。 另外，爲了確保該防水區隔的防水性能，所以藉由溫 水而使上升的內壓確實地逃逸至外部至爲重要。這個緣 故，在本實施形態，爲了將在二次防水區隔上升的內壓確 實地逃逸至一次防水區隔，因此設置微細孔膜的出口過濾 器（v e n t f i 11 e r )。而且，爲了將一次防水區隔的內壓往 外部逃逸，因此在後述的電源電纜63使用附管電纜。藉 此。能使用管的空洞部分，並透過電源箱1 3而將內壓逃 逸至外部。 藉由通電於電熱器3 7，構成直接、加熱積存水槽3 1 內的水。 在該積存水槽3 1的另一方的側壁（在第3圖的右側 壁）’形成有循環璋3 1 a ’在該循環璋3 1 a的入口 ’女裝 有泵過濾器3 9。在形成有該循環埠3 1 a的側壁之外側，如 - 11 - 200528083 (8) 第3圖所不設置有循環泵4 〇。該循環泵4 〇的吸入口氣密 地連結在循環埠3 1 a，且在其排出口的一端連結吐出軟水 管4 1。該吐出軟水管4〗的另一端往上方立起（參照第5 圖），並到達熱交換水槽3 2的側壁之預定位置，在該位 置氣密地插通於側壁並與上述噴射噴嘴3 6結合。這個緣 故，一旦驅動循環泵4 0時，積存水槽3 1內的溫水通過循 環埠3 1 a、循環泵4 0、及吐出軟水管4 1而到達噴射噴嘴 3 6，從噴射噴嘴3 6朝向熱交換水槽3 2內噴射。 而且，在積存水槽3 1的底部形成有排出埠3 1 b。該排 出瑋3 1 b ’在積存水槽31的下側與排水閥5 0 (三向閥） 的吸入埠連結。在該排水閥5 0，除了吸入璋之外，設置有 二個排水埠，因爲其中一方構成通常排水通道，所以透過 止回閥5 1而到達通常排水口 5 2。該通常排水口 5 2 (參照 第5圖）連接在排水管。因爲另一方的排水ί阜構成使用於 緊急時的緊急排水通道，所以依舊透過緊急排水口 5 3 (參 照第5圖），而例如朝向浴槽下的排水空間並經常開放。 這個緣故，藉由以控制訊號來控制排水閥5 0的電磁 部，而能切換成閉（排水OFF )、開1 (通常排水）、及 開2 (緊急排水）的三個狀態。 而且，防水罩2 0的底面，如第3圖〜第5圖所示， 在其大致中央的位置透過段差部2 0 a而形成階段狀，在該 段差部2 0 a朝橫向安裝有通常排水口 5 2及緊急排水口 5 3。藉由該橫向安裝，而構成容易安設作業或維修管理。 另一方面，在積存水槽3 1的下側’除了上述排水機 -12- 200528083 (9) 構之外’也設置有加水機構。具體上，在上 2 0a，如第5圖所示，設置有供水口 54，在該供 構成供給有從未圖示的熱水供應機來的溫水。 5 4 ’如第8圖所示，透過防止水槽3 0內的水或 即污水）從加水噴嘴3 5逆流到熱水供應機的止 而與熱水供應機結合。 該止回閥5 00，與設定在加水噴嘴3 5的前端 開口端與水槽3 0內的滿水時之水面基準面之間 流用的空隙（air gap )(後述之）相輔，如果使 之防止逆流更確實的話就好極了。 而且，上述的止回閥5 0 0，也可製作成裝備 2 〇的內部側。 而且，該供水口 54，如第8圖所示，在防冰 內部，透過手動閥5 5、壓力逃逸閥5 6、熱水供 5 7、流量感測器1 1 6、熱水供應熱敏電阻器1 1 7

a的L形管3 5 1的端部其中一方 的端部使用〇環等的密封構件而氣密地結合且另一方的端 部朝向下方並配置的連接管3 5 2、以及在熱交換水槽3 2的 內部使之與L形管3 5 1的另一方的端部結合的噴嘴主體 3 5 3。在連接管3 5 2連接有上述供水軟水管6 2。而且，在 錐面壁3 2 a的外側壁面，安裝有保持L形管3 5 1及連接管 3 5 2的保持板3 5 4。 使噴嘴主體3 5 3的另一方的前端之部分彎曲成大致L 字形。噴嘴主體3 5 3，沿著熱交換水槽3 2的錐面壁而朝上 配置，並且使之彎曲成其大致L字形的前端部分之開口端 被定位成較熱交換水槽3 2的滿水時的水面基準面LV僅高 預定高度α。這個緣故，在通常的加水時，如第6圖中之 以箭號Α所示，通過供水軟水管62、連接管3 52、L形管 3 5 1、以及噴嘴主體3 5 3而到熱交換水槽3 2，亦即在積存 水槽3 1供給有從熱水供應機來的溫水。也就是，從加水 於熱交換水槽3 2的熱水供應機來的溫水儲存於積存水槽 3 1° 這個緣故，在手動閥5 5被開放的狀態下，藉由控制 訊號開閉電磁式加水閥60的話，構成能斷續控制將往從 外部的熱水供應機來的溫水之透過加水噴嘴3 5的熱交換 水槽3 2之供給。 上述噴嘴主體3 5 3的吐出側的開口端之預定高度α ， 例如，熱交換水槽3 2即使滿水（水面爲LV的位置），且 -14- 200528083 (11) 在上述止回閥5 0 0故障，又引起自來水斷水或故障時，設 定在能防止所謂其水或溫水（當污水看待）吸進並逆流到 噴嘴主體3 5 3的情事之高度爲2 5 m m或2 5 m m以上之値。 而且，加水噴嘴3 5的設置之做法，並不限定於詳如 上述第6圖的構造，例如也可構成如第7圖所示。根據該 第7圖所示的構造的話，在熱交換水槽3 2的錐面壁3 2 a 的其中一部份形成向內側沉陷的凹部32b，利用該凹部 32b並安裝加水噴嘴35。 也就是，該加水噴嘴3 5，具備如第7圖所示，相當於 凹部32b的位置之在熱交換水槽32的肩部朝向水槽內側 並使之氣密地突出設置的噴嘴主體3 6 1、以及貫通且氣密 地設置在該肩部的連接管3 62。在連接管3 62，在熱交換 水槽32的外側連接有從下方延伸來的供水軟水管62。噴 嘴主體3 6 1的另一方的端部如圖示，被彎曲成倒V字狀， 其前端的開口端傾斜朝向積存水槽3 2的內側。從此時的 開口端，到熱交換水槽3 2之滿水時的水面LV的距離，與 上述同樣地，因爲防止水槽3 0 ( 3 2 )內的污水之逆流，所 以設定在預定値a ( 2 5 m m以上）。 在如此的錐面壁3 2 a的其中一部份藉由形成沉陷在內 側的凹部3 2b，而沒有將加水噴嘴3 5形成安裝在積存水槽 3 2的錐面壁3 2 a用的孔之必要，在凹部3 2 b的部分，能確 保安裝加水噴嘴3 5的空間。這個緣故，能將加水噴嘴3 5 迂迴錐面壁32a並簡單地安裝。加水噴嘴35自體也具有 所謂以其構造就可的優點。 -15- (12) (12)200528083 而且，在防水罩2 0的底部的預定位置，連接在與電 源箱1 3之間的電熱器電源用的電纜6 3、各種的電子電路 電源用的電纜6 4、及通訊電纜6 5爲氣密地連結。此等的 電纜，雖然未圖示，但是在罩內部構成繞經必要的位置。 另一方面，上述通氣導管21，安裝在覆蓋防水罩20 的上部之頂棚體7 0。在該通氣導管2 1，將相互之間加以 間壁且隔開預定距離而形成吸引口 7 1及吹出口 7 2，如第 3圖所示。吸引口 71及吹出口 72 —起與熱交換水槽32的 內部空間連通。這個緣故，浴室（在實際上，因爲使用浴 罩而運作，所以浴槽內部）的空氣能透過吸引口 7 1而吸 進到熱交換水槽3 2，另一方構成能透過吹出口 7 2而將熱 交換水槽3 2的內部的空氣排出。 在頂罩22的正面側安裝有開閉罩22a，在不實施三溫 暖浴時，關閉該罩2 2 a (第3圖的狀態），構成封閉吸引 口 7 1及吹出口 7 2。這個緣故，防止浴槽B T的熱水或塵 埃透過吸引口 71及吹出口 72而進入到蒸氣產生裝置1 1 內。在實施三溫暖浴時，如第5圖所示，開啓該罩22a， 設置有能維持其開放狀態的機構。 而且，在熱交換水槽32的頂棚體70，如第3圖所 示，安裝成作爲氣體液體分離用的障礙構件的分離器73 朝向熱水槽3 2的內部而垂下。該分離器7 3位在吸引口 7 1 及吹出口 72的中間位置，對於從吸引口 71及噴射噴嘴36 到來的噴射體安裝有如構成鈍角的錐面。另外，分離器7 3 的下端的位置，位在較吹出口 72還下側的位置，藉此， -16- (13) (13)200528083 從吸引口 7 1及噴射噴嘴3 6來的噴射體構成不直接地到達 吹出口 7 2。 這個緣故，在該分離器73高溫的空氣·液體的混合 體藉由衝突而氣液分離，僅飽和水蒸氣從熱交換水槽32 通過吹出口 72而被排出。 一旦將此詳述時，藉由泵4 0而循環至噴射噴嘴3 6的 溫水，從形成在該噴射噴嘴3 6之複數的噴射孔朝向熱交 換水槽3 2的內部而以高速來噴射。能以伴隨該噴射的摩 擦來拉攏成透過吸引口 7 1而捲入浴槽內的空氣。 該吸引，藉由如下的理由而能構成。藉由向熱交換水 槽3 2內所噴射的溫水流，而對水槽內的空氣給予有運動 能量，利用該空氣在水槽內移動，因爲在吸引口 7 1的附 近產生負壓，所以藉由該負壓而能從吸引口 7 1拉攏空 氣。 而且，溫水是因爲從複數的噴射孔被同時地高速噴 射，所以與熱交換水槽3 2的內部之空氣的接觸面積變 多，更多的空氣透過吸引口 71而被吸引到水槽內。 該被吸引的空氣因爲在熱交換水槽3 2內與高溫水 (所噴射的溫水）並行，所以被加熱及加濕。該被加熱· 加濕的空氣與水的混合體’其中一部份與分離器7 3的傾 斜面衝突，並且剩餘的一部份與熱交換水槽3 2的壁面衝 突。藉由該衝突，引起氣液分離，可分離成飽和水蒸氣與 水。水直接地或流到壁面而落下到積存水槽3 1，且被回 收。另一方面，飽和水蒸氣透過吹出口 7 2而朝向浴槽並 -17- (14) 200528083 被排出。 而且，如從第3圖可理解，在熱交換水槽3 2 之外側，在迴避吐出軟水管4 1的狀態下且在與溫 接觸的狀態下設置有控制基板8 0。在該控制基板 裝有擔負蒸氣產生裝置Π的控制之中樞的控制電族 電子零件。 該控制電路8 1，如第8圖所示，具備微電腦（ 機）9 0，利用給予記載在該微電腦90使關於蒸氣 置1 1的驅動·控制的處理實行的程序之程式，來 使用來實現如此的驅動•控制之手段的其中一部份 地實現。在該微電腦9 0的記憶體（未圖示），預 有如此的程式。 另外，在控制電路8 1，作爲微電腦90的周邊 界面而在同一的控制基板8 0上實裝有各種的電路 電路，包括A/D變換器92〜95 ;檢測電路96、97 驅動電路9 8〜1 0 0。該各種的電路，與蒸氣產生裝霭 的各種之檢測手段及驅動手段電性地連接，接收· 檢測手段所檢測的訊號而送至微電腦90，並且構成 微電腦9 0的處理而輸出的控制訊號接收·變換並 驅動手段。 一旦將此具體性地說明時，在吸引口 7 1及 72，分別設置有作爲檢測溫度的檢測手段之熱敏 1 1 0、1 1 1，該熱敏電阻器1 1 0、1 1 1的檢測訊號分 至A/D變換器92、95。 的右壁 水等無 80，實 ^ 81的 微處理 產生裝 構成可 功能性 先收藏 電路及 。在該 ;以及

感測器1 1 3的檢測手段被送至檢測電路9 7。在接近該積存 水槽3 1的底部的預定位置’安裝有提供比較用的基準訊 號的共通基準面感測器1 1 4，該共通基準面感測器ί 1 4的 檢測訊號作爲基準訊號而送至檢測電路9 6、9 7。此等的基 準面感測器1 1 2〜1 1 4，特別是因爲要求有檢測精度，所以 在水到達感測器的位置時使用同爲通路（〇 N )的電極開 關。 另外，在積存水槽3 1之中，較上述的下限基準面感 測器Π 3還下側，在幾乎接近於同水槽3 1的中央部的位 置，安裝有溫水熱敏電阻器1 1 5，該溫水熱敏電阻器115 的檢測訊號被送至A/D變換器93。 插入於加水水源管路的熱水供應熱敏電阻器1 1 7的檢 測訊號被送至A/D變換器94，並且流量感測器1 1 6的檢 測訊號被直接地送至微電腦90。 另--方面，從微電腦90接收控制指令的驅動電路 98、99、以及100，構成分別將其驅動訊號輸出到泵40、 排水閥50、電磁式加水閥60。從排水閥50來的訊號被直 接地輸出到微電腦90。 而且，在防水罩2 0的內部，在接近其底部的位置設 -19- 200528083 (16) 置有漏水檢測感測器1 1 8，該感測器1 1 8的檢測訊號被直 接地送到微電腦90。另外，設置在熱交換水槽32的上端 部之連動用簧式開關1 1

Description of the invention [Technical field to which the invention belongs] The present invention. It relates to a three-heating steam generating device installed in a bathtub of a general household and generating steam for a three-bath bath. In particular, it relates to a three-boiler steam generating device for installing on a ribbed surface of a bathtub with a small amount of free space. Design of the components of the device. [Prior art] In recent years, from the standpoint of beauty or health maintenance, there has been proposed a method of using a triple warm bath, which is a method or a device that can implement the triple warm bath even in ordinary households. The simplest warm bath in ordinary homes is to release hot water to the bath to half full (hip bath), cover the bath cover to the shoulders of the bather and enter the bath. Thereby, a sauna can be enjoyed by the steam generated in the bathtub. However, in the case of the three-warm bath method, it is a simple method. The steaming temperature is insufficient, and the effect is not sufficient. Therefore, a sanitary space is formed by using the entire bathroom, and the proposal is known as a sanitary bather. For example, as shown in Japanese Patent Application Laid-Open No. 5_3 3 7 1 62 (Document 1), a steam ejection unit for ejecting steam generated by the steam generation unit into the bathroom is provided. Once the steam from the steam generating part is supplied into the steam ejection part and diffused, it is discharged from the ejection port of the steam ejection part into the bathroom. In addition, in Japanese Patent Application Laid-Open No. 200-5 5 3 97 (Document 2), Japanese Patent Application No. 200528083 (2) has another structure for using the entire bathroom as a three-warm space. According to this, the three-heater main body is installed in the bathroom, for example, beside the bathtub. The main body of the three-warming device has a negative pressure generated by the warm water spraying from the nozzle and the air sucked into the bathroom by a fan provided behind the nozzle, so that the air and the warm water spraying from the nozzle mixing. It is made such that heated air is discharged through a duct into a bathroom, and warm water droplets adhering to the duct are collected in a warm water recovery tank and accumulated. The recovered water is reheated and sprayed from a nozzle to form a circulation type warming device. Furthermore, in Japanese Patent No. 3406967 (Document 3), there is another proposal for using the entire bathroom as a three-warm space. The steam generating device proposed in the reference 3 is provided with a steaming means, a circulating means for circulating warm water used in the steam generating means, a means for supplying (supplying) water or warm water to the circulating means, and the like. The air supply means for the steam supply air generated by the steam generation means. In particular, the supply means such as water includes a supply source such as water, and a pipe interposed between the solenoid valves, as seen in Reference 3. A supply source such as water is a hot water supply device that uses tap water and supplies warm water or warm water at a predetermined temperature. Water or warm water using this tap water as a water source constitutes a drain pan that supplies (supplies) to a part of the circulation means. As shown in the aforementioned documents 1 to 3, even in general households, it is possible to use a bathroom to form a space for warmth and implement a warmth bath. However, the conventional sanitary devices and steam generating devices described in the above-mentioned documents 1 to 3, because the sanitary space is formed by using the entire bathroom, have been accused of various problems. The first problem is that condensation on the wall surface of the bathroom may cause so-called mold. The second problem is that as a whole, the inside of the bathroom is more than ^ 31. Bathers in warm baths are prone to breathing difficulties, which makes women and other users unsatisfactory. In addition, the third problem is that since the entire bathroom is supplied with steam, the waiting time is long until the temperature and humidity are suitable for the sauna. At the same time, as the fourth problem is that the waiting time is long, it has been pointed out that the use of so-called electric energy or water resources is increasing. These problems are apparent from the fact that the entire bathroom is a three-warm space. For the sake of the above-mentioned hip bath, for example, if the three-warm space can be left in the bathtub, such problems can be suppressed or solved. However, in order to generate a three-warm space in a bathtub of an ordinary family using a current three-warm device or a steam generating device, such a device usually has to be installed in a bathroom where it is difficult to secure such a large space, because the device ’s The size is too large, and the shape of the device is different, so it is very difficult to ensure the installation place. If the setting is enabled, the inconveniences caused by the narrowing of the bathing place will be a lot. [Summary of the Invention] The present invention has been developed in view of such a conventional problem, and provides a small-sized, shape that can be easily installed in a narrow space, and can be easily installed in a bathtub used in a general home or the like, and can be easily A steam generating device having a bath as a three-warm space is used for this purpose. In order to achieve the above-mentioned object, according to the present invention, it is provided with a water tank having two opposite side wall surfaces in a predetermined direction of 7-200528083 (4), and a predetermined position below one of the two side wall surfaces installed in the water tank.

A separator for gas-liquid separation facing the inside of the water tank. At the upper part of the water tank, a suction port for external air suction, which communicates with the inside of the water tank, is formed at a position on the spray nozzle side than the separator, and a steam outlet for steam blowout, which communicates with the inside of the water tank, A position opposite to the suction port of the separator. According to the present invention, various constituent elements are arranged by utilizing the functions of the lower and upper parts of the sink, providing a small size and a shape that can be easily installed in a narrow space, and can be easily installed in a bathtub used in general households and the like. Easily utilize a steam generator with a bath as a three-warm space. [Embodiment] Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

With this double waterproof partition, the electric heater 37 is more surely protected. In addition, in order to ensure the waterproof performance of the waterproof segment, it is important that the rising internal pressure is reliably escaped to the outside by warm water. For this reason, in this embodiment, in order to reliably escape the internal pressure rising in the secondary waterproof segment to the primary waterproof segment, a microporous membrane outlet filter (v e n t f i 11 e r) is provided. In order to escape the internal pressure of the primary waterproof partition to the outside, a tube cable is used for the power cable 63 described later. Take this. The hollow part of the tube can be used to escape the internal pressure to the outside through the power supply box 1 3. When the electric heater 37 is energized, the water in the water storage tank 3 1 is directly heated. On the other side wall (on the right side wall in FIG. 3) of the reservoir tank 31, a circulation 璋 3 1a is formed. At the entrance of the circulation 璋 3 1a, a pump filter 39 is provided. On the outside of the side wall on which the circulation port 3 1 a is formed, as in-11-200528083 (8) The circulation pump 4 is not provided in FIG. 3. A suction port of the circulation pump 40 is air-tightly connected to the circulation port 3 1 a, and a soft water pipe 41 is connected to an end of a discharge port thereof. The other end of the spouted soft water pipe 4 rises upward (refer to FIG. 5), and reaches a predetermined position on the side wall of the heat exchange water tank 32, where it is hermetically inserted into the side wall and communicates with the above-mentioned spray nozzle 36. Combined. For this reason, once the circulation pump 40 is driven, the warm water in the storage tank 31 passes through the circulation port 3 1 a, the circulation pump 40, and the soft water pipe 41 to reach the injection nozzle 36, and faces from the injection nozzle 36. The heat exchange water tank 32 is sprayed inside. A drain port 3 1 b is formed at the bottom of the storage water tank 31. The discharge port 3 1 b ′ is connected to the suction port of the drain valve 50 (three-way valve) on the lower side of the storage tank 31. The drain valve 50 is provided with two drain ports in addition to the suction port. One of them forms a normal drain passage, and therefore passes through the check valve 51 to reach the normal drain port 52. The normal drain port 5 2 (see Fig. 5) is connected to a drain pipe. Because the other side's drainage constitutes an emergency drainage channel used in an emergency, it still passes through the emergency drainage opening 5 3 (see Figure 5), and for example, faces the drainage space under the bath and is often open. For this reason, by controlling the electromagnetic part of the drain valve 50 with a control signal, it can be switched into three states of closed (drainage OFF), open 1 (normally drained), and open 2 (emergency drained). In addition, as shown in FIGS. 3 to 5, the bottom surface of the waterproof cover 20 passes through the step portion 20 a at a substantially central position to form a step shape. Normal drainage is installed in the step portion 20 a in a lateral direction. Port 5 2 and emergency drainage port 53. This horizontal installation facilitates installation work or maintenance management. On the other hand, a water supply mechanism is provided on the lower side of the storage tank 31 in addition to the above-mentioned drainage machine -12-200528083 (9) structure. Specifically, as shown in Fig. 5, a water supply port 54 is provided in the upper 20a, and hot water from a hot water supply machine (not shown) is supplied to the supply structure. As shown in FIG. 8, 5 4 ′ is combined with the hot water supply device by preventing the water in the water tank 30 (ie, sewage) from flowing back from the water supply nozzle 35 to the hot water supply device. This non-return valve 5 00 complements the air gap (described later) for the flow between the open end of the front end of the watering nozzle 35 and the water level reference surface when the water tank 30 is full of water. It would be great to prevent countercurrents. Furthermore, the above-mentioned check valve 500 can also be manufactured on the inside side of the equipment 200. Moreover, as shown in FIG. 8, the water supply port 54 passes through the manual valve 5 5, the pressure escape valve 5 6, the hot water supply 5 7, the flow sensor 1 1 6, and the hot water supply in the anti-icing interior. The resistor 1 1 7 is connected to the water supply soft water pipe 62 with a water supply valve 60 and a fixed valve 61. The water supply soft water pipe 62 is vertically connected to the side of the tapered surface having the heat exchange water tank 32 as shown in FIG. Wall) 3 2 a water nozzle 35. The water supply nozzle 35, supply 62, and water supply port 54 are provided by using tap water as a water source to supply water before or after warming to the water tank 30 (heat exchange water donation constitutes one of the supply channels of the present invention. The water-filling nozzle 35, as shown in FIG. 6, is provided with a tapered surface wall 32a of the heat 32 from the inside to the outside and the stepped water at one end described by □ 54. The addition of 0 0 is used to prevent such water from being reversed in the waterproof cover (the filter and the electromagnetic junction of the cover 20. The airtight wall (conical surface water soft water pipe water supply source 132) is formed, the exchange water tank is penetrated and the phase is- 13- 200528083 (10) One of the ends of the L-shaped pipe 3 5 1 that uses a sealing member for the tapered wall 3 2 a and is arranged airtight, and one of the ends of the L-shaped pipe 3 5 1 that penetrates the tapered wall 3 2 a A connecting pipe 3 5 2 which is airtightly connected at the end using a sealing member such as a 0 ring and the other end faces downward, and is connected to the L-shaped pipe 3 5 1 inside the heat exchange water tank 3 2 The other end of the nozzle body 3 5 3 is connected to the connection pipe 3 5 2 to the above-mentioned water supply soft water pipe 6 2. A holding plate 3 5 4 for holding the L-shaped pipe 3 5 1 and the connecting pipe 3 5 2 is attached to the outer side wall surface of the tapered wall 3 2 a. The other end of the nozzle body 3 5 3 is bent. The nozzle body 3 5 3 is arranged upward along the tapered wall of the heat exchange water tank 32, and is bent so that the open end of the front end portion of the heat exchanger water tank 3 is positioned relatively to the heat exchange water tank 3 2 When the water level is full, the water level reference plane LV is only a predetermined height α. For this reason, during normal water filling, as shown by the arrow A in FIG. 6, the water supply soft water pipe 62, the connecting pipe 3 52, and the L The pipe 3 5 1 and the nozzle body 3 5 3 reach the heat exchange water tank 3 2, that is, the storage water tank 3 1 is supplied with warm water from a hot water supply machine. The warm water from the hot water supply machine is stored in the storage tank 3 1 °. When the manual valve 55 is opened, the electromagnetic water supply valve 60 is opened and closed by the control signal, so that it can be intermittently controlled from the outside. Of hot water from a hot water supply machine through the heat exchange water tank 3 2 of the water supply nozzle 3 5 The predetermined height α of the open end on the discharge side of the nozzle body 3 5 3, for example, even if the heat exchange water tank 3 2 is full of water (the position of the water surface is LV), and -14-200528083 (11) is in the check valve 5 0 0 When the tap water is broken or broken, set the height to prevent the so-called water or warm water (when treated with sewage) from sucking in and flowing back to the nozzle body 3 5 3. The height is 25 mm or 25 mm. The arrangement of the water nozzle 35 is not limited to the structure shown in FIG. 6 in detail, but may be structured as shown in FIG. 7 for example. According to the structure shown in FIG. 7, a concave portion 32b is formed in a part of the tapered surface wall 3 2a of the heat exchange water tank 32, and the water supply nozzle 35 is attached to the concave portion 32b. That is, as shown in FIG. 7, the water adding nozzle 35 is provided with a nozzle body 3 6 that is provided at a position corresponding to the recessed portion 32 b at the shoulder of the heat exchange water tank 32 toward the inside of the water tank and protrudes airtightly. And a connecting pipe 3 62 provided through the shoulder in an air-tight manner. To the connection pipe 3 62, a water supply soft water pipe 62 extending from below is connected to the outside of the heat exchange water tank 32. As shown in the figure, the other end of the nozzle body 3 6 1 is bent into an inverted V shape, and the open end of the front end is inclined toward the inside of the reservoir 32. The distance from the open end at this time to the water surface LV when the heat exchange water tank 32 is full of water is the same as the above, because the backflow of the sewage in the water tank 3 0 (3 2) is prevented, so it is set to a predetermined value 値 a (2 5 mm or more). In such a part of the tapered wall 3 2 a, a recessed portion 3 2b sunk in the inside is formed, and it is not necessary to form a watering nozzle 35 to form a hole for the tapered wall 3 2 a to be installed in the reservoir 32, In the portion of the recessed portion 3 2 b, a space for installing the watering nozzle 35 can be secured. For this reason, the water supply nozzle 3 5 can be bypassed to the tapered wall 32 a and simply installed. The watering nozzle 35 itself has the advantage of having a so-called structure. -15- (12) (12) 200528083 In addition, at a predetermined position on the bottom of the waterproof cover 20, a cable for a heater power supply connected between the power supply box 13 and a cable for various electronic circuits 6 3. 6 4 and communication cable 65 are airtightly connected. Although these cables are not shown in the figure, they need to be routed inside the cover. On the other hand, the ventilation duct 21 is attached to a ceiling body 70 that covers an upper portion of the waterproof cover 20. The ventilation duct 21 is formed with a partition wall and a predetermined distance from each other to form a suction port 7 1 and a blow port 7 2 as shown in FIG. 3. The suction port 71 and the blower port 72 communicate with the internal space of the heat exchange water tank 32 together. For this reason, the air in the bathroom (actually, is operated by using a bath cover, so the air in the bathtub) can be sucked into the heat-exchanging water tank 3 2 through the suction port 7 1, and the other is configured to be able to pass the heat through the air outlet 7 2. The air inside the exchange water tank 32 is exhausted. An opening-and-closing cover 22a is attached to the front side of the top cover 22, and when the three-temperature heating bath is not performed, the cover 2a is closed (the state shown in Fig. 3) to form a closed suction port 71 and a blowing port 72. For this reason, hot water or dust in the bathtub B T is prevented from entering the steam generating device 1 1 through the suction port 71 and the blow port 72. When the warm bath is performed, as shown in FIG. 5, the cover 22 a is opened, and a mechanism capable of maintaining the open state is provided. Further, as shown in Fig. 3, the ceiling body 70 of the heat exchange water tank 32 is attached with a separator 73 serving as a barrier member for gas-liquid separation, and hangs down toward the inside of the hot water tank 32. The separator 73 is positioned at a position intermediate between the suction port 71 and the blowout port 72, and a conical surface that forms an obtuse angle is attached to the spray body coming from the suction port 71 and the spray nozzle 36. In addition, the position of the lower end of the separator 7 3 is located at a position lower than the blower outlet 72, and as a result, -16- (13) (13) 200528083 ejection bodies from the suction port 71 and the ejection nozzle 36 The composition does not reach the outlet 7 2 directly. For this reason, the high-temperature air-liquid mixture in the separator 73 is separated into gas and liquid by collision, and only saturated water vapor is discharged from the heat exchange water tank 32 through the air outlet 72. Once described in detail, the warm water circulated to the spray nozzle 36 by the pump 40 is sprayed at a high speed from a plurality of spray holes formed in the spray nozzle 36 toward the inside of the heat exchange water tank 32. The friction caused by the jet can be used to draw air that is drawn into the bathtub through the suction port 71. This attraction can be constituted for the following reasons. The warm water flow sprayed into the heat exchange water tank 32 gives motion energy to the air in the water tank, and uses this air to move in the water tank, because negative pressure is generated near the suction port 71, so the Negative pressure can draw air from the suction port 71. In addition, since the warm water is sprayed simultaneously from a plurality of spray holes at high speed, the contact area with the air inside the heat exchange water tank 32 is increased, and more air passes through the suction port 71 and is sucked into the water tank. The attracted air is heated and humidified in parallel with the high-temperature water (hot water sprayed) in the heat exchange water tank 32. A part of the heated and humidified air-water mixture 'collides with the inclined surface of the separator 73, and the remaining part collides with the wall surface of the heat exchange water tank 32. This conflict causes gas-liquid separation and can be separated into saturated water vapor and water. The water falls directly on the wall surface or falls to the storage water tank 31 and is recovered. On the other hand, the saturated water vapor passes through the air outlet 72 and is directed toward the bath, and is discharged at -17- (14) 200528083. As can be understood from Fig. 3, a control substrate 80 is provided on the outside of the heat exchange water tank 3 2 in a state in which the soft water pipe 41 is avoided and in contact with the temperature. The control board is provided with control electronics which are responsible for the control center of the steam generator Π. The control circuit 81, as shown in FIG. 8, is provided with a microcomputer (machine) 90, and is implemented by using a program given to the microcomputer 90 to execute a process for driving and controlling the steam setting 1 1 to be used. Part of this means of driving and controlling is realized. The memory (not shown) of the microcomputer 90 has such a program. In addition, in the control circuit 81, various circuit circuits, including A / D converters 92 to 95, are installed on the same control substrate 80 as the peripheral interface of the microcomputer 90. The detection circuits 96 and 97 drive circuits 9 8 ~ 1 0 0. The various circuits are electrically connected to various detection means and driving means of the steam generating device, and receive and detect signals detected by the detection means and send them to the microcomputer 90, and receive control signals outputted by the microcomputer 90 processing. Transform and drive the means. Once this is explained in detail, the suction ports 7 1 and 72 are respectively provided with thermal sensors 1 1 0 and 1 1 1 as detection means for detecting temperature, and the thermistors 1 1 0 and 1 1 1 The detection signal is distributed to the A / D converters 92 and 95. The right wall of water and so on without 80, real ^ 81 micro-processing generation device composition can be functional first collection circuit and. In this; and [1 1 conversion to be sent by output to the secondary outlet resistor -18- 200528083 (15) In addition, an overflow is provided at a predetermined position of the edge (upper limit) of the hot-parent water exchange tank 3 2 The current (0 F) of the reference surface sensor 1 12 is sent to the detection circuit 9 6 by the detection signal of the reference surface sensor 1 12. Moreover, the upper limit of the side wall of the accumulated water tank 3 i is still slightly lower, and the upper limit of the cycle 3 1 a is also located, and the lower limit reference surface sensor 1 1 3 is provided. The reference surface senses The detection means of the device 1 1 3 is sent to the detection circuit 9 7. A common reference surface sensor 1 1 4 that provides a reference signal for comparison is installed at a predetermined position near the bottom of the storage water tank 31, and a detection signal of the common reference surface sensor 141 is sent as a reference signal. To detection circuits 9 6 and 9 7. These reference surface sensors 1 1 2 to 1 1 4 are particularly required to have detection accuracy, so when water reaches the position of the sensor, an electrode switch which is also a passage (ON) is used. In addition, a warm water thermistor 1 1 5 is installed in the storage water tank 31 at a position lower than the lower limit reference surface sensor Π 3 described above, and at a position close to the center of the same water tank 31. The detection signal from the warm water thermistor 115 is sent to the A / D converter 93. The detection signal of the hot water supply thermistor 1 1 7 inserted in the water supply line is sent to the A / D converter 94, and the detection signal of the flow sensor 1 16 is directly sent to the microcomputer 90. On the other hand, the drive circuits 98, 99, and 100 that receive control instructions from the microcomputer 90 constitute output signals of the drive signals to the pump 40, the drain valve 50, and the electromagnetic water supply valve 60, respectively. The signal from the drain valve 50 is directly output to the microcomputer 90. Furthermore, inside the waterproof cover 20, -19- 200528083 (16) is located near the bottom of the waterproof cover 20. A water detection sensor 1 1 8 is placed, and the detection signal of the sensor 1 1 8 is directly sent to Microcomputer 90. In addition, the detection signal of the interlocking spring switch 1 19 provided at the upper end of the heat exchange water tank 32 is also directly sent to the microcomputer 90. Figure 9 shows the power of the part other than the steam generating device with the power box as the center. Sexual block diagram. In FIG. 9, the power circuit of the power supply box 13 is shown in a block diagram. As shown in the figure, an insulating transformer 12 and a power supply board 1 2 1 are provided. The power supply board 121 includes power supply circuits 122 and 123; a microcomputer 124; a relay 125; a double breaking relay 126; and a drive circuit 127. The power supply circuit 122 receives a commercial AC power supply, generates a necessary operating voltage in the microcomputer 124, and supplies the operating voltage to the microcomputer 124. A commercial power supply is connected to another power supply circuit 1 2 3 through a relay 125 and an insulating transformer 120. The power supply circuits 1 2 3 are various power circuits and drive circuits 1 2 7 on the control board 80 in the steam generating device 11 and supply necessary operating voltages for these. The relay 1 2 5 receives a control signal from the microcomputer 1 24 when necessary, and can cut off such a power supply passage. A commercial power source is connected to the electric heater 37 through a double-break relay 126, and such electric power is supplied to the electric heater 37. This relay 126 also receives control from the microcomputer 124 when necessary, so that it can cut off its power supply through the channel. The double-break relay 126 and the power circuit 123 are connected to the steam generating device 11 via individual power cables 63 and 64, respectively. -20- (17) (17) 200528083 The drive circuit 1 2 7 rotates and drives the cool wind device 1 2 (fan) in accordance with a command from the microcomputer 1 2 4. The cool air device 12 is mounted on the wall surface of the bathroom B R, which is substantially opposite to the head of the user who uses the bathtub 10. For this reason, although a user who performs a three-bath bath operates the cool wind device 12 and the parts other than the head are exposed to the steam in the bath 100, the head can receive a cool wind feeling by receiving the cool wind. The microcomputer 124 has computer circuits such as a CPU, a memory, an interface, and the like, so that it is recorded in its memory in advance, and the desired functions are realized by sequentially executing a computer program. Such functions include a function of supplying necessary power to the steam generating device i i, a function of cutting off the power supply in an emergency, and a function of driving the cool air device 12 in accordance with an instruction from a user. In order to perform these functions, the microcomputer 1 24 is connected to the microcomputer 90 on the control board 80 of the steam generating device 11 through the communication cable 65, and is connected to the normal state, leakage, etc. Information such as abnormal conditions. In addition, the above-mentioned communication cable 65 is also connected to the remote controller 14 and the power supply box! Between the microcomputer 1 2 3 of 3 and the microcomputer 90 of the steam generating device 11 1, the operation information of the remote control 14 executed by the user is transmitted to the two microcomputers 124 and 90. With the above configuration, the arrangement of the main constituent elements of the steam generating device Π of this embodiment is not as patterned as shown in FIG. 10. That is, the steam generating device 11 includes a storage water tank 31 and a heat exchange water tank 32, which are integrally formed with a water tank 30 sharing a common internal space. This water tank 30 has two side wall surfaces S 1 and s 2 facing each other in a predetermined direction along the rib surface of the bath tank 10. The electric heater 37 is installed at a predetermined position below one of the side wall surfaces S1 of the water tank, and warms hot water or water stored in the water tank 3Q. The discharge water soft pipe 4 1 (flow path) is connected to a predetermined position below the other side wall surface S2 of the water tank 30, and the circulation loop 3 1 a is connected to a predetermined nozzle 36 provided above the side wall surface s 2. A circulating pump 40 is inserted in the spouting soft water pipe 41, and the circulating pump 40 sucks up the warm water in the water tank 30 (the storage water tank 31), and sprays the nozzle 36 into the water tank 300. . The separator for gas-liquid separation is installed in the water tank 30 (the heat exchange water tank 3: at the upper part of the central portion along the above-mentioned rib surface) toward the inside of the water tank 30. In addition, in the water tank 30 (the storage water tank The upper part of the water tank 30 is formed with a suction port 7 1 for outside air communication with the inside of the water tank 30, and is located at a position on the side of the ejection nozzle 36 than the separator 7 3, and is formed inside the water tank 30. The blow-out port 72 for communicating air blowing is located on the side opposite to the suction port 71 of the pinch separator 73. In addition, the soft water 41 connected to the circulation port 3 1 a and the spray nozzle 36 is passed through the water tank 30. One of the side wall surfaces S 2 is disposed outside and the pump 40 is inserted into the spouting water pipe 41 outside the water tank 30. The water tank 30 is formed by storing warm water or water in the lower position as described above. The storage water tank 31 and the heat exchange water tank 3 2 formed on the upper part of the storage water tank 31 constitute 'place the electric heater 37 and the circulation tank 3 1 a on both side wall surfaces S 1 and S2 of the storage water tank 31' The spray nozzle 36 is placed on the other side wall surface S 2 of the heat exchange water tank 32. The water storage tank The heat exchange water tank 32 is formed integrally with each other to form a common internal connection to the nozzle, which is connected to the 73) water continuously by the steam pipe installation 3 1 empty -22- 200528083 (19). Moreover, at least the water tank 30, the discharge water softening pipe 41, and the circulation pump 40 are housed in the same waterproof cover 20. Furthermore, at a position above the water surface LV when the water tank 30 (heat exchange water tank 3 2) is full, a water supply source using tap water as a water source is provided to supply water before or after heating. The water filling nozzle 35 connected to the water softening pipe 6 2 of the water tank 30 is arranged to set the position of the open end for water filling of the water filling nozzle 35 to a predetermined height (for example, 25 mm) from the water surface LV (refer to FIGS. 6 and 7). Figure). The steam generating device for warmth is mounted on the rib surface RM in a state where the suction port 71 and the blowing port 72 project above the rib surface R M and face the inner direction of the bath. In this way, a steam generating device for warming three ribs which can also be installed in a general-purpose bathtub is constructed. In addition, the arrangement structure of the water tank is not limited to the one described in FIG. 10, and for example, as shown in FIG. 11, a storage water tank 31 and a heat exchange water tank 32 can be formed to have a mutual relationship with each other. A different internal space 'is also provided with a communication passage CM that communicates the internal spaces of the two water tanks. Through this communication passage cm, warm water from the hot water supply machine that adds water to the heat exchange water tank 32, or water droplets during gas-liquid separation recovered in the heat exchange water tank 32 can be sent to and collected in the storage water tank 3 1 . The essentials of the operation of the steam generating device of this embodiment will be described with reference to Fig. 12. This operation is performed mainly around the microcomputer 90. And, in the steam generating device 1, when the water is added, the temperature of the water (warm water) supplied from the hot water supply machine -23- 200528083 (20) is set to 37 to 50 ° C. The processing performed by the microcomputer 90 is `` standby. Prepared zone fci process "(the separate process for the process of maintaining the steam generating device 1 1 in standby or switching, or the preparation operation for starting the mist operation), which includes the" preparation operation "( The warm water suitable for the temperature of the three-bath bath and the amount suitable for the operation of the mist is ensured in the treatment of the storage tank 31, the "mist operation" (using the warm water prepared by the preparation operation) and corresponding to the user's Remote control operation to generate steam (mist) from the air outlet 7 2 of the steam generating device 1 1), and "temperature setting process to blow out steam" (temperature setting process to make steam generated during mist operation) Various processing. Fig. 12 illustrates the process of returning from the standby state to the standby state after preparing for operation. According to this, when the user presses the preparation switch of the remote control 14 (time 11) in the standby state, the above-mentioned preparation operation is performed and the necessary amount and temperature of warm water are secured at the start of the mist operation (time t2) . In this preparation operation, the water tank 30 (the storage water tank 31 and the heat exchange water tank 3 2) and the parts communicating with it are subjected to high-temperature sterilization. After the preparation, when the user presses the mist switch of the remote controller 4 (time t3), the mist operation is started, and it becomes a warm bath (see FIG. 2). When the three-bath bath continues for a predetermined time (for example, 15 minutes) (time t4), the steam generating device 11 enters a standby state for a certain period (for example, 1 minute). During this standby time (time t4 ~ t5), the user can continue the warm bath again. When such a mist switch is pressed (time-24-200528083 (21) Hai U t4 ^), the mist operation is re-entered from this point. . During the second warm bath, that is, before the user reaches a predetermined time (for example, 15 minutes), when the user presses the mist switch (time 16), the user enters the standby time again (time t6 to t7). In this standby state, the user can stop the sauna, and when the preparation switch is pressed (time 16 /), the steam generating device 11 performs drainage (time 16 / ~ t8) and returns to the standby state. In this way, the user can implement the mist operation and enjoy the sauna. For this reason, according to the bath triple warming system of this embodiment, since the triple warming space is not formed by using the entire bathroom as before, it is possible to almost eliminate the generation of mold or the like caused by the dew condensation on the wall surface of the bathroom of the triple warming bath. In addition, the triple-warming system for the bathtub is capable of substantially reducing the breathing difficulty peculiar to the triple-warm room because the steam is sprayed into the bathtub and sprayed, and a cover such as a bath cover is covered and used. Moreover, steam can also be used to create a space with a warm environment because it can be completed inside the bathtub, so that a comfortable temperature and humidity state can be obtained in a short time. That is, compared with a sanitary system using a bathroom, the so-called short waiting time can be completed conveniently. In addition, in the short waiting time, the use of electric energy or water resources is reduced, which can provide a warming system that meets the requirements of cost saving and resource saving. In particular, it is suitable for ordinary baths (full-body baths, half-body baths, and the like) and generates steam, and the eyes are warmed by the black heat trapped in the baths. Use 'can be provided as a system suitable for general home. In this case, in a bathtub suitable for general households, if there is a small space of -25-200528083 (22), such a steam generating device 11 is installed at a position above and below the rib surface which can be easily secured, and the steam can be made. Created and sprayed towards the bathtub. The steam generating device 11 itself is in a mounted state, and has a substantially rectangular parallelepiped-shaped water tank 30 with a short-axis direction orthogonal to the direction along the rib surface as a long-axis direction and a narrow-width feeling. The necessary constituent elements are arranged along the long axis direction of the water tank 30. Furthermore, since the storage water tank 31 is formed in the lower part of the water tank 30 and the heat exchange water tank 32 is formed in the upper part, it is possible to store / warm warm water, circulate and spray warm water, attract external air, and gas-liquid Separation and steam generation, steam blow-out, recovery of water droplets generated during gas-liquid separation, and replenishment of warm water from hot water supply are performed in the water tank 30 as the center, and almost wasteful space is almost eliminated It has a high mounting density and is miniaturized. In particular, since the width (ie, shape) in the short axis direction of the sink 30 (actually the waterproof cover 20) can be minimized to a minimum, it is relatively easy to use the space above and below the rib surface of the bath. Ground setting. For this reason, it is possible to provide a steam generating device for warmth of the bathtub, which can be easily used in ordinary households, in a relatively easy state, ensuring that the installation place is relatively easy, without sacrificing the space of the bathing place. In addition, a water supply channel (including a water supply nozzle 35, a water supply soft water pipe 62, and a water supply pipe 62) for supplying water before or after heating to the water tank 30 (or the storage water tank 3 1) from a water supply source using tap water as a water source is provided. The flow path of the water supply port 54), the open end of the supply channel is set at a position higher than the water surface LV when the water tank 30 is full of water, and is arranged to remain between the water surface and the water surface -26- 200528083 (23 ) A gap of a predetermined distance. For this reason, 'in the case of preventing the malfunction of the backflow machine or the abnormality of the water cut off, for any reason such as negative pressure, the case where water (warm water) flows into the open end of the supply channel', that is, , Even in the case of going back to the current situation ', can certainly prevent such a situation. For this reason, it is possible to prevent the sewage (tap water in contact with the air outside the water pipe) and protect the water source pipeline. In addition, in preparation for operation, it is generally made to sterilize bacteria and the like at high temperature, so that it is possible to provide a sanitary system in consideration of hygiene. By automatically performing high-temperature sterilization, the user can eliminate the labor of cleaning the sink and the like for countermeasures against germs, and can provide an excellent sanitary system that is easy to use. In addition, as a control object, instead of the temperature in the bath, it is easy to control the temperature by using the blowing temperature of the steam from the air outlet, and the so-called user's sensibility can be increased and decreased by adjusting the current temperature. The temperature designation method is adopted to adjust the steam temperature in the bath simply and accurately. In addition, the configuration of the steam generating device 11 of the above embodiment can be changed into various forms. For example, by attaching a vibrating material to the outside surface of a water tank (storage water tank 31, heat exchange water tank 32), and inserting a molded steel (SUS) into a separator 73, it is possible to accompany warm water from the spray nozzle 36. The low frequency noise generated by the high-speed injection is reduced. In addition, in order to shorten the time for preparing the heat source or the time for high-temperature sterilization, attach a heat-insulating material to the outer surface of the water tank 30, and place the waterproof area once. -27- (24) (24) 200528083 The air volume in the space between the hoods 20 is designed to be the minimum to be effective. In addition, the present invention is not limited to the configuration of the above-mentioned embodiment, and can naturally be modified into various forms according to the gist of the scope of patent application. [Industrial Applicability] As described above, the steam generating device of the present invention can be compact and easily installed in a narrow space, and can be easily installed in a bathtub used in a general home or the like. For this reason, if the steam generating device is used, the bath can be used simply and efficiently as a sauna.
