【産業上の利用分野】
本発明は、熱水にて循環管路を洗浄し、その殺菌浄化後直後における洗浄熱水を浴槽内に逆流するのを防止した浴水循環装置における管路殺菌浄化装置に関する。
【0002】
【従来の技術】
従来の浴水循環装置は、長期間の使用により装置本体と配管に微生物膜が付着することがあるために安全衛生問題の外、ある一定期間毎に装置を殺菌、洗浄する必要があった。またその方法は浴槽内の湯に直接殺菌剤を投入し、浴水循環装置を循環させるものであった。
【0003】
そのため、浴槽の湯に殺菌剤を投入するのに、多量の薬品を使わなければならず、不経済であったり、薬品使用後は浴槽を洗浄しなければならなかった。このようなことから出願人は、循環管路内のみを熱水にて殺菌・洗浄する装置を開発したが、特に、連結管路箇所で止めたときに、殺菌浄化部本体が浴槽よりも上側箇所に位置しているときには、熱水循環作業停止直後に逆流して浄化した熱水が浴槽内に浸入して、熱水による熱湯危険性があったり、或いは浴槽内を汚すこともあった。
【0004】
【課題を解決するための手段】
そこで、発明者は、前記課題を解決すべく、鋭意,研究を重ねた結果、本発明を、浴水を低温から高温に加熱可能としたヒータと、微細なごみ及び汚れなる不純物を浴水から濾過するろ過装置と、浴水を循環させるための循環ポンプと、該循環ポンプにて浴水が浴槽から浴槽に戻るように循環する循環管路と、該循環管路の吸込み側寄りの適宜な箇所と前記循環管路の流出側寄りの適宜な箇所とを連結する連結管路と、前記循環管路で連結管路の接続箇所よりも吸込み側寄りの循環管路に設けた開閉弁と、前記連結管路と循環管路との連結箇所に設けた第1切換弁と、前記循環管路中に設けた前記循環ポンプと前記ヒータとの間の適宜の箇所と、前記連結管路の前記循環管路との連結部と前記ろ過装置との間の適宜の箇所との間に設けられた副連結管路と、前記副連結管路と前記循環管路との結合箇所に設けられた第2切換弁と、且つ前記循環管路上においての前記ヒータと副連結管路との間の適宜の箇所に設けられた第3切換弁と、前記各弁を制御するための弁制御手段とからなり、管路洗浄時には、該弁制御手段により前記第1切換弁、第2切換弁、第3切換弁の切換後、前記開閉弁を閉鎖して循環管路内の浴水をヒータにて高温にしつつ連結管路を介して循環可能とし、排水時には、前記弁制御手段により前記第1切換弁、第2切換弁、第3切換弁の切換後、前記開閉弁を開放して前記循環管路内で浄化した浴水を前記第3切換弁に設けた排出管から浴槽外に排出するようにしてなることを特徴とする浴水循環装置における管路殺菌浄化装置としたことにより、熱水にて循環管路を洗浄することができ、前記の課題を解決したものである。
【0005】

【0006】
連結管路5は、前記循環管路4の吸込み側寄りの適宜な箇所と、前記循環管路4の流出側寄りの適宜な箇所とを連結するように構成され、前記循環ポンプP,ヒータ1,殺菌装置2,ろ過装置3が配置された循環管路4と連結管路5とで閉ループが構成される。前記循環管路4において、前記連結管路5の両端の結合箇所の一方よりも吸込み側を給水側管路4aと、その他方よりも流出側を流出側管路4bとそれぞれ称する。前記給水側管路4a及び流出側管路4b上には、前記循環ポンプP,ヒータ1,殺菌装置2,ろ過装置3は設けられないように構成されている。前記循環ポンプP,ヒータ1,殺菌装置2,ろ過装置3,連結管路5,給水側管路4aと流出側管路4bとを除く循環管路4が、ケーシングとしての殺菌浄化部本体A内に収納されている。前記連結管路5と、前記循環管路4の流出側管路4bとの適宜の部位との連結部に三方弁からなる切換弁V1が設けられている。
【0007】
また、循環ポンプPとヒータ1との循環管路4の適宜の箇所と、前記連結管路5の連結部と前記ろ過装置3との間の適宜の箇所との間に副連結管路6が設けられている。前記ろ過装置3よりの副連結管路6と前記循環管路4との結合箇所には三方弁としての第2切換弁V2が設けられ、且つ前記循環管路4上においての前記ヒータ1と副連結管路6との間の適宜の箇所に,三方弁なる第3切換弁V3が設けられている。該第3切換弁V3には排出管7が設けられ、該端部は浴槽10の外側に位置するように配置されている。前記給水側管路4aの吸込み口には、プレフィルタ8が、前記流出側管路4bの流出口には、ジェット噴流が出るように噴出部9が設けられている。前記切換弁V1と前記連結管路5とを総称して循環ユニットCと称する。また、前記プレフィルタ8と噴出部9とを含む箇所を吸排ユニットBと称する。
【0008】
熱水にて管路殺菌浄化するときには、開閉弁Vが閉鎖されて給水側管路4aは遮断され、循環管路4において、切換弁V1,第2切換弁V2及び第3切換弁V3を介して、給水側管路4aと流出側管路4bとが閉鎖された状態で、前記循環ポンプP,ヒータ1,殺菌装置2,ろ過装置3を配置された循環管路4と連結管路5とで閉ループを構成して、この内部の浴水が循環ポンプPの動作にて循環する。
【0009】
本発明では、弁制御を含めて全て自動操作にて行なわれる。この構成は、図3に示すように、ブロック図にて構成されている。即ち、中央演算処理装置21(CPU)が設けられ、熱水管路殺菌洗浄の開始・終了等を制御する熱水殺菌洗浄指令手段22と、前記開閉弁V,切換弁V1,第2切換弁V2及び第3切換弁V3の切換を制御する弁制御手段23と、第1温度センサー25及び第2温度センサー26を切換制御する温度センサー切換手段24と、ランプ制御手段27と、ヒータ制御手段28とが設けられている。前記熱水殺菌洗浄指令手段22は、循環管路内を熱水洗浄するために洗浄開始時間を設定する時間設定部と、設定された洗浄開始時間と洗浄時間を記憶する時間記憶部と、洗浄開始時間と洗浄時間を適宜変更する時間変更部とを有している。前記中央演算処理装置21,熱水殺菌洗浄指令手段22,弁制御手段23,温度センサー切換手段24,ランプ制御手段27,ヒータ制御手段28等を総称して制御部Dと称する。
【0010】
前記第1温度センサー25は浴槽湯として所望の湯温(例えば,42℃等)を検知するものであり,第2温度センサー26は、熱水管路洗浄時において、65℃乃至70℃以上か否かを検知するものである。この2つの温度センサーを通常運転モード,熱水殺菌洗浄モードにおいて前記温度センサー切換手段24にて切換えるものである。また、ランプ制御手段27にてUVランプのON,OFFが制御される。さらに、ヒータ制御手段28にてヒータ1のON,OFFが制御されている。
【0011】
図4は、本発明の、循環管路内の湯温制御及び開閉弁V,切換弁V1,第2切換弁V2及び第3切換弁V3の切換指令の制御のフローチャートであり、図5のフローチャートの「まる1」(機種依存文字)の状態から、所定の設定時間後に、全水系熱水殺菌洗浄モードとなり(S11参照)、温度センサー切換手段24にて切換えられ(S12参照)、第2温度センサー(熱水タイプ)26がONとなる(S13参照)。このときには、ヒータ1はON状態を保持している。そして殺菌装置2のUVランプが消灯する(S14参照)。そして、弁制御手段23にて切換弁V1はポート「まる3」(機種依存文字)からポート「まる1」(機種依存文字)に流通して、管路内循環に変更するように切換えられ(S15参照)、第2切換弁V2はポート「まる3」(機種依存文字)からポート「まる1」(機種依存文字)に流通するように切換えられ(S16参照)、第3切換弁V3はポート「まる3」(機種依存文字)からポート「まる1」(機種依存文字)に流通するように切換えられる(S17参照)。さらに、且つ開閉弁Vは閉鎖状態を保持する(S18参照)。そして、前述の熱水殺菌洗浄モードを行ったときから、熱水殺菌洗浄指令手段22が動作して、熱水管路殺菌洗浄開始するまでの温度上昇を勘案した所定時間を基に浴水温度を計測し(S19参照)、そして、循環管路4内の温度が第2温度センサー26を介して所定温度(例えば70℃)か否かを自動的に検知し(S20参照)、所定温度を超えない場合にはヒータ1のON状態を保持する。
【0012】
また、管路内の浴水が所定温度(例えば70℃)となった場合には、ヒータ1がOFFとなる(S21参照)。この状態において、循環ポンプPのポンプ圧にて閉ループ管内の浴水が循環して熱水管路殺菌洗浄作業が開始となり、この状態は図1に示す通りである。そして、前記熱水管路殺菌洗浄作業開始のときから、熱水殺菌洗浄指令手段22が動作して、熱水管路洗浄する所定時間(70℃で約5分)を計測し(S22参照)、この所定時間経過したか否かを判断し(S23参照)、所定時間が経過しない場合には前記S21の手前に戻り、その所定時間が経過した場合には、今度は熱水排出モードとなる(S24参照)。
【0013】
そして、弁制御手段23にて切換弁V1はポート「まる1」(機種依存文字)からポート「まる2」(機種依存文字)に通常運転時と同一となるように切換えられ(S25参照)、第2切換弁V2はポート「まる2」(機種依存文字)からポート「まる1」(機種依存文字)及び「まる3」(機種依存文字)に流通するように保持され(S26参照)、第3切換弁V3はポート「まる1」(機種依存文字)からポート「まる2」(機種依存文字)に流通するように保持される(S27参照)。且つ開閉弁Vは開放され(S28参照)、洗浄した熱水は排出管7を介して浴槽10外に排出されるものである。その熱水が排出される所定時間をタイマー計測し、所定時間経過したか否かを判断し(S29参照)、その所定時間が経過した場合には熱水殺菌洗浄が終了したか否かを判断する(S30参照)。終了したとすると、今度は、温度センサー切換手段24にて温度センサーが切換えられ(S31参照)、第1温度センサー(通常タイプ)25がONとなる(S32参照)。そして、ヒータ1がONとなり(S33参照)。UVランプが点灯して(S34参照)、この状態から通常運転状態のフローチャートの「まる2」(機種依存文字)に戻る。
【0014】
なお、浴水循環装置を通常運転状態のフローチャートは、図5に示すように、浴水循環装置を駆動するか否かを判断し(S1参照)、浴水循環装置を駆動する場合には、浴水循環装置の電源をONとし(S2参照)、循環ポンプPを駆動させ(S3参照)、ヒータ1をONとし(S4参照)、さらに殺菌装置2のUVランプを点灯させて(S5参照)、第1温度センサー(通常タイプ)25がONとなり、浴水循環装置を駆動させる。そのとき、熱水管路洗浄をするか否かを判断し(S7参照)、熱水管路殺菌洗浄させるとすると、図4のフローチャートの▲1▼に進み、そして自動のサブルーチンのフローチャート▲1▼〜▲2▼(図4参照)となって、再び、図5のフローチャートの▲2▼に戻る。熱水管路殺菌洗浄をしないと判断すると、そのまま駆動させ、浴水循環装置を停止させるか否かを判断し(S7参照)、停止する場合には終了し、停止しない場合には、浴水循環装置の電源をONするS2の手前に戻る。また、S1において、浴水循環装置を駆動しない場合には終了する。
【0015】
また、第2の実施の形態では、図6に示すように、第1の実施の形態において、前記開閉弁Vを、逆止弁V4に換えたものであり、該逆止弁V4内を流通する浴水は浴槽10側から循環管路4のみに流通するようにしてなる浴水循環装置における管路殺菌浄化装置であり、他の構成は、第1の実施の形態と同一である。フローチャートにおいては、弁制御において開閉弁Vの開放又は閉塞がないものであり、他は同一である。
【0016】
また、図7に示したものは、前記循環ユニットCを、前記殺菌浄化部本体Aの外部に備え、且つ該殺菌浄化部本体Aの外側位置で、且つ吸排ユニットBに近接して設けられている。さらに、このときには、前記開閉弁V又は逆止弁V4は具備されていない。この場合のフローチャートも、第2の実施の形態の場合と同一である。
【0017】
【発明の効果】
まず、請求項1の発明では、第1に前記開閉弁Vの存在にて、熱水循環殺菌洗浄を終了したときであって、その殺菌洗浄装置本体Aが浴槽10の浴水面の上側に存在したとしても、殺菌浄化部本体A内の洗浄した熱水が浴槽10内へ逆流することを防止でき、第2に別途殺菌剤を投入する手間が省け、管路洗浄がいつでも簡単にできるし、特に、熱水殺菌で行なうために、レジオネラ菌のみならず、クリプトスポリジウム菌等に対しても死滅させることができ、極めて安全且つ衛生的である等の効果を奏する。
【0018】
特に、請求項1の発明では、熱水殺菌する循環回路が構成されている状態で運
転停止した場合に、熱水洗浄した浴水が浴槽10へ逆流するのを防止して浴槽水の汚染を防ぐことができるし、浴水循環装置(24時間風呂装置)と循環ユニットCを結ぶ配管が完全に遮断されるために浴水交換や装置本体のメンテナンスが容易にできる利点がある。さらに、浴水循環装置と循環ユニットCを結ぶ配管が完全に遮断されるため殺菌浄化部本体Aと浴槽10の相対的な位置(高さ)の制限が無くなり、設置が自由にできる効果もある。

[0011]
FIG. 4 is a flowchart of hot water temperature control in the circulation line and control of switching commands of the on-off valve V, the switching valve V1, the second switching valve V2, and the third switching valve V3 according to the present invention. After a predetermined set time from the state of “maru 1” (model-dependent character), it becomes the all-water-based hot water sterilization washing mode (see S11), and is switched by the temperature sensor switching means 24 (see S12), and the second temperature. The sensor (hot water type) 26 is turned on (see S13). At this time, the heater 1 is kept on. Then, the UV lamp of the sterilizer 2 is turned off (see S14). Then, the switching valve V1 is circulated from the port “maru 3” (model-dependent character) to the port “maru 1” (model-dependent character) by the valve control means 23 so as to be changed to circulation in the pipeline ( The second switching valve V2 is switched so as to flow from the port “maru 3” (model-dependent character) to the port “maru 1” (model-dependent character) (see S16), and the third switching valve V3 is the port. Switching from “maru 3” (model-dependent character) to port “maru 1” (model-dependent character) is performed (see S17). Furthermore, the on-off valve V maintains a closed state (see S18).

If the predetermined time has elapsed, the hot water discharge mode is set (S24). reference).
[0013]
Then, the switching valve V1 is switched from the port “maru 1” (model-dependent character) to the port “maru 2” (model-dependent character) by the valve control means 23 so as to be the same as in normal operation (see S25). The second switching valve V2 is held so as to circulate from the port “maru 2” (model-dependent character) to the ports “maru 1” (model-dependent character) and “maru 3” (model-dependent character) (see S26).

The on-off valve V is opened (see S28), and the washed hot water is discharged out of the bathtub 10 through the discharge pipe 7. A predetermined time for discharging the hot water is measured by a timer to determine whether or not the predetermined time has elapsed (see S29). When the predetermined time has elapsed, it is determined whether or not the hot water sterilization cleaning has been completed. (See S30). If completed, the temperature sensor switching means 24 switches the temperature sensor (see S31), and the first temperature sensor (normal type) 25 is turned on (see S32). Then, the heater 1 is turned on (see S33). The UV lamp is turned on (see S34), and the state returns to “maru 2” (model-dependent character) in the flowchart of the normal operation state from this state.
[0014]
As shown in FIG. 5, the flowchart of the normal operation state of the bath water circulation apparatus determines whether or not to drive the bath water circulation apparatus (see S1). 1 is turned on (see S2), the circulation pump P is driven (see S3), the heater 1 is turned on (see S4), and the UV lamp of the sterilizer 2 is turned on (see S5). The sensor (normal type) 25 is turned on to drive the bath water circulation device. At that time, it is determined whether or not hot water pipe cleaning is performed (see S7), and if hot water pipe sterilization cleaning is performed, the process proceeds to (1) in the flowchart of FIG. {Circle over (2)} (see FIG. 4), and the flow returns to {circle around (2)} in the flowchart of FIG. If it is determined that the hot water pipe sterilization cleaning is not performed, it is driven as it is, and it is determined whether or not to stop the bath water circulation device (see S7). Return to just before S2 when the power is turned on. If the bath water circulation device is not driven in S1, the process ends.
[0015]
Further, in the second embodiment, as shown in FIG. 6, in the first embodiment, the on-off valve V is replaced with a check valve V4, and the inside of the check valve V4 is circulated. The bath water to be circulated is the pipeline sterilization and purification device in the bath water circulation device configured to circulate only from the bathtub 10 side to the circulation pipeline 4, and the other configuration is the same as that of the first embodiment. In the flowchart, there is no opening or closing of the on-off valve V in the valve control, and the others are the same.
[0016]
7 is provided with the circulation unit C outside the sterilization purification unit main body A, and provided outside the sterilization purification unit main body A and close to the intake / exhaust unit B. Yes. Further, at this time, the on-off valve V or the check valve V4 is not provided. The flowchart in this case is also the same as that in the second embodiment.

【The invention's effect】
First, in the first aspect of the invention, first, when the hot water circulation sterilization washing is completed due to the presence of the on-off valve V, the sterilization washing apparatus main body A exists above the bath water surface of the bathtub 10. Even so, it is possible to prevent the washed hot water in the sterilization and purification unit main body A from flowing back into the bathtub 10, and secondly, it is possible to easily clean the pipeline at any time, eliminating the need to add a separate sterilizer. In particular, since it is performed by hot water sterilization, not only Legionella bacteria but also Cryptosporidium bacteria can be killed, and the effects of being extremely safe and hygienic are exhibited.
[0018]
In particular, in the invention of claim 1, when the operation is stopped in a state where a circulation circuit for sterilizing hot water is configured, the bath water washed with hot water is prevented from flowing back to the bathtub 10 to contaminate the bathtub water. Since the piping connecting the bath water circulation device (24-hour bath device) and the circulation unit C is completely cut off, there is an advantage that the bath water exchange and the maintenance of the device main body can be easily performed. Further, since the pipe connecting the bath water circulation device and the circulation unit C is completely cut off, there is no restriction on the relative position (height) of the sterilizing and purifying section main body A and the bathtub 10, and there is an effect that the installation can be freely performed.
