200522929 (1) 九、發明說明 【發明所屬之技術領域】 本發明係關於設置在一般家庭的浴室或浴槽等，使用 以自來水來作爲水源的水（包括溫水）而使之產生二溫暖 浴用的蒸氣之三溫暖用蒸氣產生裝置，特別是，關於防止 一但供給於該三溫暖用蒸氣產生裝置的水之往自來水管的 逆流。 【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係放流熱水於浴 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。 φ 可是，在該三溫暖浴方法的情況，到底是簡便的方法 ，蒸氣的溫度不足，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。 -5- 200522929 (2) 另外，在日本特開2 0 0 0 - 5 5 3 9 7號公報（文獻2 ) ’提 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係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。水等供給源係使用自來水，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，享受三溫暖浴。 在上述先前之浴室用的三溫暖裝置及蒸氣產生裝置， -6 - 200522929 (3) 因爲配合一般家庭，所以作爲蒸氣產生之用的水源，幾乎 依舊利用一般引進到各家庭的自來水。例如，如在上述文 獻3所提案，從熱水供應暖氣機來的供水·熱水供應配管 連結到蒸氣產生裝置的泄水盤。 然而，在利用如此的自來水之供給通道（配管）的情 況，因爲趨向蒸氣產生裝置的構造之小形化等/所以構成 接近於如此的供給通道（配管）之開口端積存於泄水盤內 或積存水槽內的水（溫水）面的構造較多。這個緣故，一 旦，吐出於水槽等的水（溫水：包括一旦使用於蒸氣產生 的水（溫水）），由於在自來水斷水或故障時的負壓等之 任何的理由，再度，逆流到供給通道（配管），並擔憂造 成所謂自來水被污染的情事。 在防止該逆流，通常，考慮有在往蒸氣產生裝置之水 的供給通道設置止回閥。然而，如此的供給通道直接連結 在泄水水槽的構造之情況，在止回閥破損、故障時，一旦 被吐出的水逆流到自來水的水源管路之憂慮依然存在。 【發明內容】 本發明係有鑒於如此之先前的問題而加以開發完成者 ，使以自來水來作爲水源的水或溫水積存於水槽，在使用 該水槽內的水或溫水而產生三溫暖用的蒸氣時，以提供能 確實防止從水槽往自來水的水源管路之一旦被吐出的水（ 溫水）之逆流的三溫暖用蒸氣產生裝置作爲其目的。 爲了達成上述目的，根據在本發明之一型態的話，具 -7- 200522929 (4) 備使水積存的水槽、及從以自來水來作爲水源的水供給源 供給加溫前或加溫後的水到上述水槽的供給通道，在製作 成使用積存於上述水槽的水而使之產生三溫暖浴用的蒸氣 的三溫暖用蒸氣產生裝置之中，將上述供給通道的開口端 配置成設置在較上述水槽之滿水時的水面還高的位置並在 與該水面之間保留預定距離的空隙爲其特徵。例如，上述 水供給源係使用自來水的熱水供應器，並使之積存於上述 水槽的水爲從上述熱水供應器來的溫水。也可在從上述供 給通道的上述水供給源到上述開口端的經過通道之途中設 置止回閥。 另外，根據本發明之另外的型態的話，具有：能將溫 水積存的積存水槽、使之與該積存水槽連通，並且能將外 部的空氣吸進的吸引口及使之連通於上述蒸氣的吹出口並 形成了熱交換水槽、在上述積存水槽，供給從以自來水來 作爲水源的熱水供應機來的上述溫水的供給通道、使積存 於上述積存水槽的上述溫水在上述熱交換水槽內透過噴嘴 而噴射的泵手段、在朝向上述熱交換水槽並從上述噴嘴所 噴射的溫水與從上述吸引口所吸引的外部空氣之間使熱交 換進行並使蒸氣產生的蒸氣產生手段、以及伴隨上述蒸氣 的產生並將分離的水滴回收到上述積存水槽的回收手段， 具備：設置成使上述蒸氣從上述吹出口朝向浴槽內並吐出 的蒸氣產生部、至少上述積存水槽及熱交換水槽之內部的 水位、以及檢測上述積存水槽內的溫水之溫度的檢測手段 、將利用上述蒸氣產生部的蒸氣之產生狀態對應於指令資 -8- 200522929 (5) 訊與藉由上述檢測手段而檢測的資訊而控制的控制手段， 將上述供給通道的開口端配置該供給通道成設置在較上述 熱交換水槽的滿水時之水面還高的位置並在與該水面之間 保留空隙爲其特徵。 而且，在本發明之中，所謂「蒸氣」之用語，未必侷 限於1 〇 0 °C的蒸氣，如在浴槽內例如構成4 0 °c前後的溫度 ，當作也包含100°C以下的蒸氣溫度之槪念而使用。 根據本發明的話，具備從以自來水來作爲水源的水供 給源供給加溫前或加溫後的水於水槽（或積存水槽）的供 給通道，將該供給通道的開口端設置成較水槽的滿水時之 水面還高的位置並在與該水面之間保留預定距離的空隙。 這個緣故，另外在裝備的防止逆流機器之故障時或斷水時 的異常時，由於負壓等之任何的理由，在水槽內的水（溫 水）流進了供給通道的開口端的情況，亦即，在即使欲進 行逆流的情況，也能確實防止如此的情事。這個緣故，能 避免起因於一旦從自來水管所吐出的水之污染而守護自來 水的水源管路。 【實施方式】 以下，參照添附圖面’並說明本發明的1個實施形態 〇 首先，說明使用關於本發明的三溫暖用蒸氣產生裝置 的浴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。 -9 - 200522929 (6) 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的浴槽丨〇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M。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1 1 及涼風裝置1 2。 這個緣故，蒸氣產生裝置11，雖然詳述於後，但是由 來自肋面RM突出的部分朝向浴槽1 0的熱水積存部（浴 槽內部）而形成噴射適溫（例如4〇 °C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 0的內部而加 以浴罩FT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1 0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）。 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 -10- 200522929 (7) 蒸氣產生裝置1 1係如第3圖所示，構成大致正方體 狀的箱體。第3圖係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）。 該蒸氣產生裝置11，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21、及覆蓋該通氣導管21的頂罩22 〇 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3 0a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。 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係直立形成。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 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 -11 - 200522929 (8) 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 (vent filter )。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13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），形成有循環埠3 1 a，在該循環璋3 1 a的入口，安裝 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 第3圖所示設置有循環泵40。該循環泵40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41。該吐出軟水管41的另一端往上方立起，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40時，積存水槽31內的溫水通過循環埠31a、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內並噴射。 -12- 200522929 (9) 而且，在積存水槽3 1的底部形成有排出璋3 1 b。該排 出埠3 1 b，在積存水槽3 1的下側與排水閥5 0 (三向閥） 的吸入璋連結。在該排水閥5 0 ’除了吸入捧之外’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連接在 排水管。因爲另一方的排水埠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，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20的底面，如第3圖所示，在其大致 中央的位置透過段差部20a而形成階段狀，在該段差部 2〇a朝橫向安裝有通常排水口 52及緊急排水口 53。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 構之外，也設置有加水機構。具體上，在上述段差部20a ’如第3圖所示，設置有供水口 5 4，在該供水口 5 4，構 成供給有從未圖示的熱水供應機來的溫水。該供水口 54， 如第6圖所示，透過防止水槽3 0內的水或溫水（亦即， 一旦從自來水的水源管路吐出的水）從加水噴嘴3 5逆流 到熱水供應機的止回閥5 00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的前端的加水用 開口端與水槽3 0內的滿水時之水面基準面之間之防止逆 -13- 200522929 do) 流用的空隙（後述之）相輔，如果使如此的水之防止逆流 更確實地的話就好極了。 而且’上述的止回閥500，也可製作成裝備在防水罩 2 0的內部側。 而且，該供水口 54，如第6圖所示，在防水罩20的 內部’透過手動閥5 5、壓力逃逸閥5 6、熱水供應過濾器 5 7、流量感測器1丨6、熱水供應熱敏電阻器丨〗7、電磁式 加水閥6 0、以及定量閥6 1而與供水軟水管6 2連結。 該供水軟水管62，往上方立起並氣密地連結在具有上 述熱交換水槽32的錐面之側壁（錐面壁）32a的加水噴嘴 35。該加水噴嘴35、供水軟水管62、以及供水口 54係從 以自來水來作爲水源的水供給源供給加溫前或加溫後的水 到水槽3 0 (熱交換水槽3 2 )，構成本發明的供給通道之 一部份。 加水噴嘴3 5，詳如第4圖所示，具備：在熱交換水槽 32的錐面壁32a從其內側朝向外側並使其中一端貫通且相 對於錐面壁32a而使用密封構件並氣密地配置之L形管 351、在貫通了錐面壁32a的L形管351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32的 內部使之與L形管3 5 I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62。而且，在 錐面壁32a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。 200522929 (11) 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353，沿著熱交換水槽32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32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4圖中之 以箭號Α所示，通過供水軟水管62、連接管3 5 2、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 〇 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 在上述止回閥500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吸進並逆流到噴嘴主體3 5 3的 情事之咼度爲25mm或25mm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4圖的構造，例如也可構成如第5圖所示。根據該 第5圖所不的構造的話，在熱交換水槽32的錐面壁32a 的其中一部份形成向內側沉陷的凹部3 2 b，利用該凹部 3 2 b並安裝加水噴嘴3 5。 200522929 (12) 也就是，該加水噴嘴3 5，具備如第5圖所示，相當於 凹部3 2 b的位置之在熱交換水槽3 2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362。在連接管3 62，在熱交換 水槽3 2的外側連接有從下方延伸來的供水軟水管6 2。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 φ 上述同樣地，因爲防止水槽3 0 ( 3 2 )內的水（溫水）之逆 流，所以設定在預定値a ( 25mm以上）。 在如此的錐面壁32a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 32的錐面壁32a用的孔之必要，在凹部32b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。 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64、及通訊電纜65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70。在該通氣導管2 ;[，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 7 1及吹出口 7 2 —起與熱交換水槽3 2的 -16- 200522929 (13) 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32，另一方構成能透過吹出口 72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22a (第3圖的狀態），構成封閉吸引 口 71及吹出口 72。這個緣故，防止浴槽BT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11 φ 內。在實施三溫暖浴時，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32的內部而垂下。該分離器73位在吸引口 71 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’ φ 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7 3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 -17- 200522929 (14) 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 〇 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32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73的傾斜 面衝突，並且剩餘的一部份與熱交換水槽32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 72而朝向浴槽並被排 出。 而且，如從第3圖可理解，在熱交換水槽3 2的右壁 之外側，在迴避吐出軟水管4 1的狀態下且在與溫水等無 接觸的狀態下設置有控制基板80。在該控制基板80，實 裝有擔負蒸氣產生裝置Π的控制之中樞的控制電路8 1的 電子零件。 該控制電路8 1，如第6圖所示，具備微電腦（微處理 機），利用給予記載在該微電腦使關於蒸氣產生裝置11 -18- 200522929 (15) 的驅動•控制的處理實行的程序之程式，來構成可使用來 實現如此的驅動•控制之手段的其中一部份功能性地實現 。在該微電腦的記憶體（未圖示），預先收藏有如此的程 式。 另外，在控制電路8 1，作爲微電腦的周邊電路及界面 而在相同的控制基板8 0上實裝有各種的電路。在該電路 ，雖然未圖示，但是包括A/D變換器、檢測電路、及驅動 電路。該各種的電路，與蒸氣產生裝置Π內的各種之檢 測手段及驅動手段電性地連接，接收•變換以檢測手段所 檢測的訊號而送至微電腦，並且構成將藉由微電腦的處理 而輸出的控制訊號接收·變換並輸出到驅動手段。 一旦將此具體性地說明時，在吸引口 7 1及吹出口 72 ’分別設置有作爲檢測溫度的檢測手段之熱敏電阻器1 1 0 、1 1 1，該熱敏電阻器1 1 〇、11 1的檢測訊號被送至控制電 路8 1。 另外，在熱交換水槽3 2的緣部（上限）的預定位置 設置有溢流（OF )基準面感測器1 1 2，該基準面感測器 1 1 2的檢測訊號被送至控制電路8 1。而且較積存水槽3 1 的側壁的上限還位在稍微下側的位置，較循環埠3 9還位 在上側的位置，設置有下限基準面感測器Π 3，該基準面 感測器1 1 3的檢測手段被送至控制電路8 1。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Π 4，該共通基準面感測器丨〗4的 檢測訊號作爲基準訊號而送至控制電路8 1。此等的基準面 -19- 200522929 (16) 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（0N )的電極開關。 另外，在積存水槽31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Π 5，該溫水熱敏電阻器115 的檢測訊號被送至控制電路8 1。 插入於加水水源管路的熱水供應熱敏電阻器1 1 7的檢 測訊號被送至控制電路8 1，並且流量感測器1 1 6的檢測訊 號被直接地送至微電腦。 另一方面，從微電腦的控制指令，作爲從控制電路8 1 來的驅動訊號而輸出到泵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。 而且，在防水罩2 0的內部，在接近其底部的位置設 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。另外，設置在熱交換水槽32的上端部 之連動用簧式開關Π 9的檢測訊號也被直接送到微電腦。 另一方面，電源箱1 3 (參照第1圖），包括對蒸氣產 生裝置Π供給必要的電源之功能、在緊急時遮斷電源之 功能、因應於利用者來的指令而使涼風裝置1 2驅動的功 能。因爲是此等的功能發揮，所以電源箱1

Description of the invention [Technical field to which the invention belongs] The present invention relates to the use of water (including warm water) as a source of water (including warm water) installed in a bathroom or a bathtub of a general household to generate a warm bath In particular, the steam generating device for triple warming is related to the prevention of backflow of water supplied to the steam generating device for triple warming to a water pipe. [Prior art] In recent years, from the standpoint of beauty or health maintenance, the use of saunas has been proposed, and a method or a device that can implement saunas even in ordinary households has been proposed. The simplest three-bath bath system is implemented in ordinary homes 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. φ However, in the case of the triple warm bath method, it is a simple method, the temperature of the steam 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 from the steam generation unit to the inside of the bathroom is provided. Once the steam from the steam generating portion is supplied to the inside of the steam ejection portion and diffused, it is discharged from the ejection outlet of the steam ejection portion into the bathroom. -5- 200522929 (2) In Japanese Patent Application Laid-Open No. 2000- 5 5 3 97 (Document 2), the proposal has another configuration for using the entire bathroom as a three-warm space. According to this, a sanitary appliance main body is installed in the bathroom, for example, next to 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. The heated air is discharged through the duct into the bathroom, and the warm water droplets attached to the duct are collected in a warm water recovery tank and stored. 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 steam supply means, a circulation means for circulating warm water used in the steam generation means, water supply means (supply) water or warm water to the circulation means, and other supply means, and 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. The 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 the bathroom to form a space for warmth and enjoy a warmth bath. In the above-mentioned bathrooms and steam generators for bathrooms, -6-200522929 (3) Because it is compatible with ordinary households, as the source of water used for steam generation, tap water generally introduced into households is still almost used. For example, as proposed in the above-mentioned Document 3, the water supply and hot water supply pipes from the hot water supply heater are connected to the drain pan of the steam generating device. However, when such a supply channel (pipe) of tap water is used, the structure of the steam generating device tends to be reduced in size, etc., and the open ends constituting such a supply channel (pipe) are accumulated in a drain pan or a water tank. The water (warm water) surface inside has many structures. For this reason, once the water (warm water: including water (warm water) generated by steam once used) is spit out of the water tank, once again, for any reason such as the negative pressure of the tap water in the event of water cut-off or failure, the flow countercurrently Supply channels (piping) and worry about what may be called contaminated tap water. In order to prevent this backflow, it is generally considered that a check valve is provided in a water supply path to the steam generating device. However, in the case where such a supply channel is directly connected to the structure of the drain tank, there is still anxiety that when the check valve is damaged or malfunctioned, the discharged water once flows back to the water pipe of the tap water. [Summary of the Invention] The present invention has been developed in view of such a previous problem, and the water or warm water using tap water as a water source is accumulated in a water tank, and the water or warm water in the water tank is used to generate a warmth. For the purpose of providing steam, the purpose is to provide a steam generating device that can prevent the backflow of the water (warm water) once discharged from the water supply pipe from the water tank to the tap water. In order to achieve the above object, according to one aspect of the present invention, there are -7-200522929 (4) a water tank for storing water and a water supply source from tap water as a water source before or after heating. The supply passage of water to the water tank is made of a steam generating device for warmth that uses the water stored in the water tank to generate steam for a warmth bath. When the water level of the water tank is full of water, it is characterized by a gap that keeps a predetermined distance from the water surface. For example, the water supply source is a hot water supplier using tap water, and the water stored in the water tank is warm water from the hot water supplier. A check valve may be provided in the middle of the passage from the water supply source of the supply passage to the open end. In addition, according to another aspect of the present invention, there is a suction water tank capable of storing warm water, communicating with the water storage tank, and a suction port capable of sucking in external air and communicating with the steam. A blow-out port is formed to form a heat exchange water tank, and a supply channel for supplying the warm water from a hot water supplier using tap water as a water source is provided in the storage water tank, and the warm water stored in the storage water tank is in the heat exchange water tank. A pump means for spraying through the nozzle inside, a steam generating means for performing heat exchange between the warm water sprayed from the nozzle toward the heat exchange water tank and the external air sucked from the suction port, and generating steam, and A recovery means that recovers the separated water droplets into the storage water tank following the generation of the vapor, includes a vapor generation unit provided to direct the vapor from the air outlet toward the bath tub, and at least the inside of the storage water tank and the heat exchange water tank The detection level of the water level and the temperature of the warm water in the storage tank will use the above The generation state of the steam in the steam generating section corresponds to the command means-8- 200522929 (5) The control means controlled by the information detected by the above-mentioned detection means, and the open end of the above-mentioned supply passage is arranged so that the supply passage is set at It is characterized that the water level is higher than the full water of the heat exchange water tank and a gap is left between the water surface and the water surface. In addition, in the present invention, the term "steam" is not necessarily limited to steam at 100 ° C. For example, if the temperature in the bath is around 40 ° c, it is considered to include steam below 100 ° C. It is used in consideration of temperature. According to the present invention, there is provided a supply channel for supplying water before or after heating in a water tank (or a storage water tank) from a water supply source using tap water as a water source, and the open end of the supply channel is set to be fuller than the water tank. When the water surface is still high, a gap of a predetermined distance is kept from the water surface. For this reason, in the case where the equipment for preventing the backflow device is malfunctioning or the water is abnormal, the water (warm water) in the water tank flows into the open end of the supply channel for any reason such as negative pressure. That is, such a situation can be surely prevented even if it is going to be countercurrent. For this reason, it is possible to prevent the water source pipe from protecting the tap water due to the contamination of the water once discharged from the tap pipe. [Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the attached drawings. ○ First, the overall configuration of a bath triple warming system using a steam generating device for warming according to the present invention will be described. Fig. 1 shows the overall structure of such a bath triple warming system. -9-200522929 (6) As shown in the figure, as an example, this bath triple warming system is a rib surface RM (edge on the short side located on the side of the foot position in the long axis direction of the bathtub BR of the bathroom BR). The steam generating device 1 1 ° is provided with a part protruding from the upper part and the remaining part can be detached or integrally installed in a suspended state 1 1 ° In addition, it is located slightly above the steam generating device n The bathroom wall surface is provided with a cool air device 12 in a state where the air outlet is facing the bath 10 side. On the back surface of the ceiling of the bathroom B R, a power supply box 13 for receiving the supply of commercial power from the outside is provided, and a heater power is supplied to the steam generator M from the power supply. In addition, in the power supply box 13, an operation signal is received from a remote controller 1 4 provided at a suitable place on a wall surface in a bathroom, and the operation signal is configured to transmit a control signal to the steam generating device 1 1 and the cool air device 1 2 according to the operation signal. . For this reason, although the steam generating device 11 is described in detail later, the protruding portion from the rib surface RM faces the hot water storage portion (inside the bath) of the bath 10 (the inside of the bath) to form a spray-appropriate temperature (eg, around 40 ° C) Vapor (mist). For this reason, when the user has completed the preparation for operation of the steam generating device 11, as shown in FIG. 2, the user enters the inside of the bath 10 and puts on the bath cover FT and retains the posture of extending his face from one of them. The operation of the steam generating device 11 is commanded from the remote controller 14. Thereby, the hot water storage part of the bath 10 is used as a three-warm space, so that a three-temperature warm bath (sweating bath) can be enjoyed while sitting in the bath. In the following, the structure and operation of the steam generating device 11 will be described in detail. The bath heating system -10- 200522929 (7) The steam generating device 1 1 constitutes a substantially cubic box as shown in FIG. 3. Figure 3 is a view (hereinafter referred to as a front view) seen from a user of the sauna (bath side). The steam generating device 11 is a constituent element constituting a casing thereof, a waterproof cover 20 functioning as a housing constituting a center, a ventilation duct 21 provided on the upper side of the waterproof cover 20, and a ceiling covering the ventilation duct 21. The cover 22 is provided inside the waterproof cover 20 with a water tank 30 which is divided and integrated into an integrated space through the segment portion 30a on the upper and lower sides. Within the water tank 30, a storage water tank 31 for holding warm water is formed in a water tank part lower than the section part 30a, and an upper water tank part constitutes a heat exchange water tank 32 for heat exchange. The in-tank filter 34 is provided in the segment part 30a. The left side wall of FIG. 3 of the heat exchange water tank 32 is attached to form a tapered surface, and the right side wall is formed upright. Among them, one of the water supply nozzles 35 for adding water to the water tank is provided on the tapered wall as described later, and the inner side of the upright wall is provided with a pump to circulate the hot water toward the water tank as described later. Spray nozzles 3 6. The storage tank 31 is formed in a substantially rectangular parallelepiped shape, and an electric heater (sheathed heaters) 37 for heating water in the water tank is provided on one of the side walls (on the left wall in FIG. 3). The electric heater 37 penetrates the side wall in an airtight state, and is provided such that the heating portion thereof is positioned inside the water tank and the terminal portion is positioned outside the water tank. The electrode portion located outside the water tank is formed with an electric heater cover 38 so as to be hermetically sealed. As a result, the electrode portions of the electric heater 37 can be covered with a double waterproof partition -11-200522929 (8) and hermetically sealed. That is, a primary waterproof partition is formed between the waterproof cover 20 and the storage water tank 31, and a secondary waterproof partition is formed inside the electric heater cover 38. 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 vent filter of a microporous membrane is provided. Furthermore, 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 13. When the electric heater 37 is energized, the water in the water storage tank 3 1 is directly heated. A circulation port 3 1 a is formed on the other side wall (on the right wall in FIG. 3) of the storage tank 31, and a pump filter 39 is installed at the inlet of the circulation 璋 3 1 a. A circulation pump 40 is provided outside the side wall on which the circulation port 3 1 a is formed, as shown in FIG. 3. The suction port of the circulation pump 40 is air-tightly connected to the circulation port 3 1 a, and a discharge water soft pipe 41 is connected to one end of the discharge port. The other end of the spouted soft water pipe 41 rises upward and reaches a predetermined position on the side wall of the heat exchange water tank 32, where it is air-tightly inserted into the side wall and combined with the above-mentioned spray nozzle 36. For this reason, once the circulation pump 40 is driven, the warm water in the storage water tank 31 passes through the circulation port 31a, the circulation pump 40, and the water discharge pipe 41 to reach the spray nozzle 36, and from the spray nozzle 36 to the heat exchange water tank 3 2 inside and spray. -12- 200522929 (9) Furthermore, a discharge tank 3 1 b is formed at the bottom of the storage tank 31. The discharge port 3 1 b is connected to the suction port 排水 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 except for the suction port. One of the drain ports constitutes 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 is connected to a drain pipe. Because the other drainage port constitutes an emergency drainage channel used in an emergency, it still passes through the emergency drainage port 5 3, 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). Further, as shown in FIG. 3, the bottom surface of the waterproof cover 20 is formed in a stepped manner through a stepped portion 20a at a substantially central position, and a normal drain port 52 and an emergency drain port 53 are horizontally installed at the stepped portion 20a. . This horizontal installation facilitates installation work or maintenance management. On the other hand, a water supply mechanism is provided below the storage water tank 31 in addition to the above-mentioned drainage mechanism. Specifically, as shown in FIG. 3, the step portion 20a 'is provided with a water supply port 54. The water supply port 54 is configured to supply warm water from a hot water supply device (not shown). As shown in FIG. 6, the water supply port 54 passes through the water or warm water in the water tank 30 (that is, once the water is discharged from the water source pipe) to flow back from the water supply nozzle 35 to the hot water supply unit. Non-return valve 5 00 is combined with hot water supply. This check valve 5 00 is provided with a gap for preventing reverse flow between the open end for water refilling set at the front end of the water refilling nozzle 35 and the water level reference surface at the time of full water in the water tank 30-13-200522929 do) (described later) It would be great to make such water repellency more reliable. Furthermore, the above-mentioned check valve 500 may be manufactured to be provided on the inner side of the waterproof cover 20. Moreover, as shown in FIG. 6, the water supply port 54 passes through the manual valve 5 5, the pressure escape valve 5 6, the hot water supply filter 5 7, the flow sensor 1 6, and the heat inside the waterproof cover 20. The water supply thermistor 丨〗 7, the electromagnetic water supply valve 60, and the quantitative valve 61 are connected to the water supply soft water pipe 62. This water supply soft water pipe 62 is erected upward and is airtightly connected to a water supply nozzle 35 having a tapered side wall (tapered surface wall) 32a of the heat exchange water tank 32 described above. The water supply nozzle 35, the water supply soft water pipe 62, and the water supply port 54 supply water before or after heating from a water supply source using tap water as a water source to the water tank 30 (heat exchange water tank 32), and constitute the present invention. Part of the supply channel. As shown in FIG. 4, the water adding nozzle 35 is provided with a tapered wall 32 a of the heat exchange water tank 32 facing from the inside to the outside, one end of which is penetrated, and a sealing member is provided to the tapered wall 32 a and hermetically arranged. One of the L-shaped pipe 351 and the end of the L-shaped pipe 351 penetrating the tapered wall 32a is a connection pipe 3 which is air-tightly connected with a sealing member such as an o-ring and the other end thereof faces downward. 5 2. A nozzle body 3 5 3 which is combined with the other end of the L-shaped pipe 3 5 I inside the heat exchange water tank 32. The above-mentioned water supply soft water pipe 62 is connected to the connection pipe 3 5 2. Further, on the outer side wall surface of the tapered wall 32a, a holding plate 3 5 4 that holds the L-shaped pipe 3 5 1 and the connecting pipe 3 5 2 is attached. 200522929 (11) The other end of the nozzle body 3 5 3 is bent into a substantially L shape. The nozzle main body 353 is arranged upward along the tapered surface wall of the heat exchange water tank 32, and the open end of the front end portion which is bent into a substantially L shape is positioned to be higher than the water surface reference surface LV when the heat exchange water tank 32 is full Only the predetermined height α is high. For this reason, when the water is normally added, as shown by an arrow A in FIG. 4, the heat is supplied to the heat source through the water supply soft pipe 62, the connecting pipe 3 5 2, the L-shaped pipe 3 5 1, and the nozzle body 3 5 3. The exchange water tank 32, that is, the accumulation water tank 31 is supplied with warm water from a hot water supply machine. That is, the warm water from the hot-water supply machine that adds water to the heat exchange water tank 32 is stored in the storage water tank 3 1 0. When the manual valve 5 5 is opened, the electromagnetic water valve is opened and closed by a control signal. At 60, it is possible to intermittently control the supply of warm water from the external hot water supply device through the heat exchange water tank 32 of the water supply nozzle 35. 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 32 is full of water (the position of the water surface is LV), and the check valve 500 fails, the tap water is cut off or At the time of failure, the degree of the event that prevents the so-called water or warm water from sucking in and flowing back to the nozzle body 3 5 3 is set to 25 mm or more. In addition, the method of installing the 'watering nozzle 35' is not limited to the structure shown in FIG. 4 in detail, but may be constituted as shown in FIG. 5 for example. According to the structure not shown in FIG. 5, a concave portion 3 2 b is formed in a part of the tapered surface wall 32 a of the heat exchanging water tank 32. The concave portion 3 2 b is used to attach a water nozzle 35. 200522929 (12) That is, as shown in FIG. 5, the water adding nozzle 35 is provided at a position corresponding to the recessed portion 3 2 b. The shoulder of the heat exchange water tank 32 faces the inside of the water tank and protrudes airtightly. The nozzle body 3 61 and the connecting pipe 362 which penetrates through and is hermetically provided on the shoulder portion. 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 φ described above, because the backflow of water (warm water) in the water tank 3 0 (3 2) is prevented, so it is set to Plan 値 a (25mm or more). In such a portion of the tapered wall 32a, the recessed portion 3 2b sunk inside is formed, and it is not necessary to form the water nozzle 35 to form a hole for the tapered wall 32a installed in the reservoir 32. The portion of the recessed portion 32b , Can ensure the space for installing water nozzle 35. 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. Furthermore, at a predetermined position on the bottom of the waterproof cover 20, a cable 6 for a heater power supply connected to the power supply box 13 and a cable 64 for various electronic circuit power supplies and a communication cable 65 are airtight. link. 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 the upper part of the waterproof cover 20. In the ventilation duct 2; [, a partition wall is formed with 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 7 1 and the blowing port 7 2 are connected to the internal space of the -16- 200522929 (13) of the heat exchange water tank 3 2. For this reason, the air in the bathroom (actually, the bath cover is used to operate, so the air inside the bathtub) can be sucked into the heat exchange water tank 32 through the suction port 71, and the other is configured to be able to exchange the heat exchange water tank through the air outlet 72. 3 2 The internal air is exhausted. An opening / 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 22a is closed (the state shown in FIG. 3), and the suction opening 71 and the air outlet 72 are closed. For this reason, hot water or dust in the bath BT is prevented from entering the steam generating device 11 φ through the suction port 71 and the blow port 72. When the warm bath is performed, the cover 22a 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. This separator 73 is located in the middle of the suction port 71 and the blow-out 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, so that the configuration of the spray body from the suction port 7 1 and the spray nozzle 36 does not reach the blower 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 rubbing with the jet -17- 200522929 (14) can be used to draw the air 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. Furthermore, since warm water is sprayed from a plurality of spray holes at the same time at high speed, the contact area with the air inside the heat exchange water tank 32 is increased, and more air is drawn. It is sucked into the water tank through the suction port 71. The attracted air is heated and humidified in parallel with the high-temperature water (hot water sprayed) in the heat exchange water tank 32. Part of the mixture of heated and humidified air and water 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 flows down to the storage water tank 31 and is recovered. On the other hand, saturated water vapor passes through the blow-out port 72, faces the bath, and is discharged. As can be understood from Fig. 3, the control board 80 is provided on the outside of the right wall of the heat exchange water tank 32 in a state in which the soft water pipe 41 is avoided and in a state without contact with warm water or the like. Electronic components of the control circuit 81, which is the control center of the steam generating device Π, are mounted on the control board 80. This control circuit 81, as shown in FIG. 6, is provided with a microcomputer (microprocessor), and uses a program given to the microcomputer to execute a process for driving and controlling the steam generating device 11 -18- 200522929 (15). Programs are used to form part of the means that can be used to implement such driving and controlling functions. Such a program is stored in the memory (not shown) of the microcomputer in advance. Various circuits are mounted on the same control board 80 as the peripheral circuit and interface of the microcomputer in the control circuit 81. Although not shown, this circuit includes an A / D converter, a detection circuit, and a driving circuit. These various circuits are electrically connected to various detection means and driving means in the steam generating device Π, receive and convert the signals detected by the detection means and send them to the microcomputer, and constitute a microcomputer output that is processed by the microcomputer. The control signal is received, converted and output to the driving means. Once this is explained in detail, the thermistor 1 1 0 and 1 1 1 which are detection means for detecting the temperature are respectively provided at the suction port 71 and the blower port 72 ', and the thermistor 1 1 0, The detection signal of 11 1 is sent to the control circuit 8 1. In addition, an overflow (OF) reference surface sensor 1 1 2 is provided at a predetermined position of an edge (upper limit) of the heat exchange water tank 32, and a detection signal of the reference surface sensor 1 1 2 is sent to the control circuit. 8 1. In addition, the upper limit of the side wall of the storage tank 3 1 is located at a slightly lower position, and the upper position of the circulation port 3 9 is at an upper position. A lower limit reference surface sensor Π 3 is provided, and the reference surface sensor 1 1 The detection means 3 is sent to the control circuit 81. At a predetermined position near the bottom of the reservoir tank 31, a common reference plane sensor Π 4 that provides a reference signal for comparison is installed, and the detection signal of the common reference plane sensor 丨〗 4 is sent as a reference signal to Control circuit 8 1. These reference planes-19- 200522929 (16) Sensors 1 1 2 ~ 1 1 4 Especially because the detection accuracy is required, when the water reaches the position of the sensor, use the same electrode (0N) as the channel switch. In addition, in the storage water tank 31, a warm water thermistor Π 5 is installed at a position near the center of the same water tank 31 than the lower limit reference surface sensor Π 3 described above. The detection signal from the hot water thermistor 115 is sent to the control circuit 81. The detection signal of the hot water supply thermistor 1 1 7 inserted in the water supply source pipe is sent to the control circuit 8 1, and the detection signal of the flow sensor 1 1 6 is directly sent to the microcomputer. On the other hand, a control command from the microcomputer is output as a drive signal from the control circuit 8 1 to the pump 40, the drain valve 50, and the electromagnetic water supply valve 60. The signal from the drain valve 50 is directly output to the microcomputer. Further, a water leak detection sensor 1 1 8 is provided inside the waterproof cover 20 near the bottom thereof, and the detection signal of the sensor 1 1 8 is directly sent to the microcomputer. In addition, the detection signal of the interlocking reed switch 9 provided at the upper end of the heat exchange water tank 32 is also directly sent to the microcomputer. On the other hand, the power supply box 1 3 (refer to FIG. 1) includes a function of supplying necessary power to the steam generating device Π, a function of shutting off the power supply in an emergency, and a cool air device 1 2 in response to an instruction from a user. Driven functionality. Because these functions are exerted, the computing device of the power supply box 13 can communicate with the microcomputer on the control board 80 of the steam generating device 11 through the communication cable 65, and can communicate the normal state and leakage current. It is connected to the destination where information such as an abnormal state is transmitted. The operation of the steam generating device Π in this embodiment is implemented mainly by a microcomputer (not shown) of the control circuit -20-200522929 (17) 81. The microcomputer responds to detection signals from various detection methods such as sensors or switches, and performs "standby and preparation segmentation processing" (relating to the process of maintaining or switching the steam generator η in a standby state, or starting Preparing operation for the operation of mist operation and its separate treatment), including "preparation operation" (treatment to ensure that warm water suitable for the temperature of the three-bath bath and an amount of warm water suitable for the operation of the mist are stored in the storage tank 31), "Mist operation" (treatment using warm water prepared by the preparation operation "and processing of generating steam (mist) from the air outlet 72 of the steam generating device 11 in accordance with the user's remote control operation), and Various types of processing including "temperature setting processing" (temperature setting processing of steam generated during mist operation). As described above, in the steam generating device 11, the water supplied from the hot water supply device (the temperature of the warm water is 37 to 50 ° C.) is used to perform the mist operation in accordance with the instructions of the user. Within the steam. For this reason, as shown in FIG. 1, the user can enjoy the warmth bath using the bath 10. According to the warmth bath heating system according to this embodiment, the warmth space is not formed by using the entire bathroom as before. Therefore, 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 three-bath 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 bath cover or the like is covered and used. In addition, the space where steam can be made into a warm environment is completed in the bathtub, so that a comfortable temperature and humidity state can be obtained in a short time. -21-200522929 (18) That is, compared with the use of a bathroom heating system, the convenience of so-called short waiting time can be obtained. In addition, in the short waiting time, the use of electric energy or water resources is reduced, which can provide a three-warm system that meets the requirements of cost saving and resource saving. In particular, it is suitable for use as a normal bath (full-body bath, half-body bath, etc.) and generates steam, and the bath can be warmed by the steam trapped in the bath. As a system for general home use. In addition, there is a supply channel (including a water supply nozzle 35, a water supply soft water pipe 62, and the like) from a water supply source using tap water as a water source to supply water before or after warming to the water tank 30 (or the storage water tank 31). The flow channel of the water supply port 54), the open end of the supply channel is arranged at a position higher than the water surface LV when the water tank 30 is full of water, and a gap with a predetermined distance is kept from the water surface. For this reason, among other abnormalities to prevent the malfunction of the countercurrent machine or when the water is cut off, for any reason such as negative pressure, even if water (warm water) in the water tank wants to enter the open end of the supply channel, In other words, even if you want to go against the current, you can certainly prevent such a situation. For this reason, it is possible to prevent the water source pipeline from being contaminated by the water that was once discharged from the pipe of the water source pipeline, and to securely protect the water source pipeline. In addition, the configuration of the steam generating device 11 of the above embodiment can be changed into various forms. For example, the tap water may be directly introduced into the water tank 30 without passing through the hot water supply device. In realizing this structure, a tap water pipe is directly connected to the water supply port 5 4, and tap water passes through the water supply soft water pipe 62 to the water supply nozzle 2005 22929 (19) nozzle 35. Thereby, tap water can be poured into the water tank 30 (the storage water tank 3 1) to a predetermined amount. In this case, the above-mentioned predetermined amount of clearance α must be provided between the water level surface of the water tank 30 when it is full of water and the open end of the watering nozzle 35. The injected water is heated to a predetermined temperature with an electric heater 37 to obtain warm water. By circulating the warm water with a circulation pump 40, steam as described above can be generated. That is, it is not necessary to use warm water from a hot water supply device. In addition, the shape of the water tank 30 (the storage water tank 31 and the heat exchange water tank 32) is not necessarily limited to those in the embodiment described above, and it can store tap water (warm water). ) In the lower part, and can ensure that the heat exchange space is in the upper part, if it has a structure that connects the two, it can form a suitable shape. For example, the storage water tank 31 and the heat exchange water tank 32 may be formed as individual storage units that are combined with each other to form an integrated storage space. Alternatively, the storage tanks may be formed as individual storage units and still be installed as individual storage units. State, and the two sink spaces are connected by the communication portion. The present invention is not limited to the structures described in the embodiments, and those skilled in the art can appropriately change and deform the present invention as long as they do not depart from the gist described in the scope of patent application. [Industrial Applicability] According to the present invention, the steam generator for warmth uses the tap water as the source of water or warm water to be stored in a water tank. When steam is generated, it is possible to prevent the water (warm water) in the so-called water tank from flowing back to the water source pipe of the tap water and contaminate the water of the tap water. For this reason, it is possible to provide a more reliable steam generator for warmth.
