In order to solve the above problems, the present invention provides a foreign matter removing means for removing foreign matter contained in water collected from a bathtub, hot water at 40 ° C. or higher by heating water after the foreign matter has been removed, A circulating hot water supply system having a heating means for chlorination and chlorine sterilization means for sterilizing the hot water, wherein the hot water after chlorine sterilization is returned to the bathtub.
The heating means includes
A heat exchanger that performs heat exchange between the heated raw water used as a heat medium and the water recovered from the bathtub, and heats the water;
A hydrogen / oxygen gas generator,
A burner using hydrogen fuel obtained from this hydrogen / oxygen gas generator,
Raw water aquarium for storing raw water such as tap water and well water heated by this burner,
Heat exchange is performed between the heated water supplied to the heat exchanger from the raw water tank to 40 to 45 ° C. and the reflux water returning from the heat exchanger to the raw water tank, and supplied to the heat exchanger. And a chiller unit that raises the temperature of the heated water to 50 to 55 ° C.

ここで、熱交換器から得られる前記温水に含まれているレジオネラ菌などを殺菌する殺菌手段を有していることが望ましい。   Here, it is desirable to have a sterilizing means for sterilizing Legionella and the like contained in the warm water obtained from the heat exchanger.

本発明の循環給湯システムでは、熱交換器の熱媒として用いる原水を加熱するための加熱源として、水素・酸素ガス発生装置と、ここから発生する水素燃料を用いるバーナーを備えている。CO2などの大気汚染物質を含む燃焼ガスを発生させることなく、しかも、効率良く原水を加熱することができる。 The circulating hot water supply system of the present invention includes a hydrogen / oxygen gas generator and a burner using hydrogen fuel generated therefrom as a heating source for heating raw water used as a heat medium of a heat exchanger. CO 2 without causing the combustion gas containing air pollutants, such as, moreover, can be heated efficiently raw water.

以下に、図面を参照して、本発明を適用した温泉の循環給湯システムを説明する。   Hereinafter, a hot water circulation hot water supply system to which the present invention is applied will be described with reference to the drawings.

図1は本例の循環給湯システムを示す概略構成図であり、図2はその概略平面構成図である。本例の循環給湯システム1は、浴槽水循環系Aと、浴槽水を再加熱するための原水循環系Bとを備えている。   FIG. 1 is a schematic configuration diagram showing a circulating hot water supply system of this example, and FIG. 2 is a schematic plan configuration diagram thereof. The circulating hot water supply system 1 of this example includes a bathtub water circulation system A and a raw water circulation system B for reheating the bathtub water.

浴槽水循環系Aは、浴槽2の水を、循環ポンプ3を用いて、浴槽2の吸入口4から回収して給湯口5から再び浴槽2に還流させる。この循環系Aには、循環経路に沿って、異物除去手段としてのヘアーキャッチャ6およびろ過器7と、熱交換器8と、殺菌手段としてのレジオネラ菌対策用のろ過器9と、塩素滅菌手段としての自動塩素滅菌装置10が配置されている。   The bathtub water circulation system A collects the water in the bathtub 2 from the suction port 4 of the bathtub 2 using the circulation pump 3 and recirculates the water from the hot water supply port 5 to the bathtub 2. In this circulation system A, along the circulation path, a hair catcher 6 and a filter 7 as foreign matter removing means, a heat exchanger 8, a filter 9 for Legionella countermeasures as sterilizing means, and a chlorine sterilizing means As an automatic chlorine sterilization apparatus 10 is arranged.

浴槽2の吸入口4から排出された浴槽水は、ヘアーキャッチャ6においてヘヤーが除去された後に、循環ポンプ3を介してろ過器7に供給される。ろ過器7内に充填されているろ材7aを流下する間に、浴槽水に含まれている異物がろ過される。ろ過後の水は、熱交換器8に供給され、ここで熱交換により加熱された後に、ろ過器9を通ってレジオネラ菌の殺菌処理が行われる。そして、自動塩素滅菌装置10によって塩素滅菌処理が行われた後に、40〜42℃の温水状態で給湯口5から浴槽2に供給される。   Bath water discharged from the suction port 4 of the bathtub 2 is supplied to the filter 7 via the circulation pump 3 after the hair is removed by the hair catcher 6. While flowing down the filter medium 7a filled in the filter 7, foreign matters contained in the bath water are filtered. The filtered water is supplied to the heat exchanger 8, where it is heated by heat exchange and then sterilized by Legionella through the filter 9. And after a chlorine sterilization process is performed by the automatic chlorine sterilizer 10, it is supplied to the bathtub 2 from the hot water supply port 5 in a 40-42 degreeC warm water state.

一方、原水循環系Bは、原水水槽21に貯留されている熱媒としての原水を、循環ポンプ22、23を用いて、原水水槽21の供給口21aから、チラーユニット24および熱交換器8を経由した後に再びチラーユニット24を通して、原水水槽21の回収口21bから原水水槽21に回収する。   On the other hand, the raw water circulation system B uses raw water as a heat medium stored in the raw water tank 21 to the chiller unit 24 and the heat exchanger 8 from the supply port 21a of the raw water tank 21 using the circulation pumps 22 and 23. After passing through, the raw water tank 21 is recovered from the recovery port 21b of the raw water tank 21 through the chiller unit 24 again.

原水水槽21にはバーナー25が付設されており、バーナー25によって原水水槽21に貯留されている原水が加熱される。バーナー25は水素ガスを燃料としており、水素ガスは水素・酸素ガス発生装置である水素燃料ユニット26から供給される。水素燃料ユニット26には原水が供給され、原水を電気分解することにより得られる水素ガスが燃料としてバーナー25に供給される。   The raw water tank 21 is provided with a burner 25, and the raw water stored in the raw water tank 21 is heated by the burner 25. The burner 25 uses hydrogen gas as fuel, and the hydrogen gas is supplied from a hydrogen fuel unit 26 which is a hydrogen / oxygen gas generator. Raw hydrogen is supplied to the hydrogen fuel unit 26, and hydrogen gas obtained by electrolyzing the raw water is supplied to the burner 25 as fuel.

原水水槽21の原水はバーナー25によって加熱されて40〜45℃の温水状態で供給口22から循環ポンプ22を介してチラーユニット24に供給される。チラーユニット24において、供給された温水が、還流する原水が放出する熱によって50〜55℃まで過熱される。チラーユニット24から出た温水は、循環ポンプ23を介して、熱交換器8に供給される。熱交換器8の内部において、浴槽2から回収された浴槽水との間の熱交換によって熱を放出した後は、チラーユニット24を経由して更に熱を放出し、20〜30℃程度の温度状態で回収口21bから原水水槽21に戻る。   The raw water in the raw water tank 21 is heated by the burner 25 and supplied to the chiller unit 24 from the supply port 22 through the circulation pump 22 in a hot water state of 40 to 45 ° C. In the chiller unit 24, the supplied hot water is heated to 50 to 55 ° C. by the heat released from the refluxing raw water. The hot water discharged from the chiller unit 24 is supplied to the heat exchanger 8 via the circulation pump 23. After releasing heat by heat exchange with the bath water collected from the bathtub 2 inside the heat exchanger 8, further heat is released via the chiller unit 24, and the temperature is about 20-30 ° C. The state returns to the raw water tank 21 from the recovery port 21b.

ここで、水素燃料ユニット26は、例えば、WO2003/048424に開示の構成とすることができる。また、レジオネラ菌対策用のろ過器9は、例えば、特開2002−191680号公報に開示の構成とすることができる。   Here, the hydrogen fuel unit 26 may have a configuration disclosed in, for example, WO2003 / 048424. Moreover, the filter 9 for Legionella countermeasures can be set as the structure disclosed by Unexamined-Japanese-Patent No. 2002-191680, for example.

以上説明したように、本例の循環給湯システム1では、浴槽水を加熱するために用いる原水を、水素燃料ユニット26から供給される水素ガスを燃料とするバーナー25を用いて加熱している。したがって、一般的なボイラーなどの加熱装置を用いる場合のような大気汚染物質を含む燃焼ガスが発生しない。また、効率良く原水を加熱することができる。よって、CO2などを発生しない省エネ型の循環給湯システムを実現することができる。 As described above, in the circulating hot water supply system 1 of this example, the raw water used for heating the bath water is heated using the burner 25 that uses hydrogen gas supplied from the hydrogen fuel unit 26 as fuel. Therefore, the combustion gas containing an air pollutant like the case where a heating device such as a general boiler is used is not generated. Moreover, raw water can be efficiently heated. Therefore, an energy-saving circulating hot water supply system that does not generate CO 2 or the like can be realized.
