PROBLEM TO BE SOLVED: To provide an apparatus of readily manufacturing a bath carbonate spring which can generate carbon dioxide in bath water continuously and maintain highly-concentrated carbon dioxide for a long period of time by rapidly, easily, and securely dissolving and stirring powdery alkaline component and acid component in the bath water.SOLUTION: A dissolving/stirring device main body of an alkaline or acid powdery component includes: a dissolving tank which takes bath water therein through a plurality of small holes arranged on a peripheral surface of the tank and makes a tank upper part above the small holes be positioned on a hot water surface and a submersible pump which is connected to a lower part of the tank and is positioned in the bath water. The powdery alkaline component or acid component input in the bath water housed in the dissolving tank through a filter is respectively and separately dissolved and stirred by receiving a swirling flow sucked by the submersible pump for circulating and refluxing hot water in a bathtub, is dropped in a solution state in the bath water of the bathtub, is repeatedly circulated and refluxed, and is diffused to make contact moderately so that the highly-concentrated carbon dioxide is continuously generated and is maintained for a long period of time.COPYRIGHT: (C)2014,JPO&INPIT【課題】 粉末状のアルカリ性成分と酸性成分との浴湯への溶解・攪拌を迅速,容易,確実になし,もって浴湯中で継続的に炭酸ガスを発生させ高濃度の炭酸ガスを長時にわたり維持することができる浴用炭酸泉の簡易製造装置の提供。【解決手段】タンク周面に配設の複数の小孔を介して内部に浴湯を取り入れてその小孔より上方のタンク上側部を湯面上に位置せしめる溶解タンクとその下方に接続して浴湯中に位置する水中ポンプとからなるアルカリ性又は酸性の粉末状成分の溶解・攪拌装置本体を具備し、溶解タンク内に収容の浴湯中に漉し器を介して投入された粉末状のアルカリ性成分又は酸性成分は夫々別々に湯船内の温水を循環還流させる水中ポンプに吸引される旋回流を受けて溶解・攪拌されて湯船の浴湯中に溶液状となって落とし込まれ繰り返し循環還流・拡散されて緩やかに接触し,高濃度の炭酸ガスが継続して発生され長時間維持される。【選択図】図1
