PROBLEM TO BE SOLVED: To make a bathing person feel satisfied throughout one year even if the season or an atmospheric temperature change by making an operation time and an operation output automatically change on the basis of the temperature environmental factor such as the season, hot water temperature and atmospheric temperature in a system for promoting a hyperthermic effect of bathing which enhances the hyperthermic effect on the bathing person by generating water streams and fine bubbles in a bathtub for a predetermined time.SOLUTION: The system for promoting a hyperthermic effect of bathing is provided with a water stream generating system for generating water streams containing bubbles and water stream containing no bubbles in the bathtub filled with hot water so as to promote the hyperthermic effect given to the bathing person, and an electronic control unit 7. The water stream generating system is provided with a pump P or a motor which becomes a power source. The electronic control unit 7 is constituted to control the operation output and operation time of the power source P so as to adjust the generation amounts of the bubbles and water streams on the basis of the atmospheric temperature information, hot water temperature information and/or season information.COPYRIGHT: (C)2012,JPO&INPIT【課題】浴槽内に水流や微細気泡を所定時間発生させることで入浴者の温熱効果を高める入浴時温熱効果促進装置において、季節や湯温や気温などの温度環境因子に基づいて動作時間や動作出力を自動的に変更させるようにして、季節や気温が変化しても一年を通じて入浴者の満足感が得られるようにする。【解決手段】入浴者に与える温熱効果を促進させるように湯張りされた浴槽内に気泡を含む水流や気泡を含まない水流を発生させる水流発生装置と、電子制御手段7とを備え、水流発生装置は、動力源となるポンプP又はモーターを備え、電子制御手段7は、気温情報・湯温情報及び/又は季節情報に基づいて気泡や水流の発生量を調整するように動力源Pの動作出力や動作時間を制御するように構成する。【選択図】図1
