PROBLEM TO BE SOLVED: To provide a carbonate spring generation device capable of efficiently generating a carbonate spring without increasing water pressure.SOLUTION: A carbonate spring generation device includes a bubble dissolved flow channel 12 in which water mixed with carbon dioxide bubbles flows. The bubble dissolved flow channel 12 includes: at least one contraction part 14 for dividing a carbon dioxide bubble and a pressure keeping part 16 for keeping pressure in the bubble dissolved flow channel 12 at the output side end of the bubble dissolved flow channel 12. An effective diameter of the bubble dissolved flow channel 12 is determined so that viscous resistance R of a bubble in water flowing, at a flow rate v, in the bubble dissolved flow channel 12 is equal to or larger than buoyant force F of a carbon dioxide bubble in the case that a diameter of the carbon dioxide bubble is a maximum diameter D which is the effective diameter. The contraction part 14 has an effective diameter smaller than that of the bubble dissolved flow channel 12.COPYRIGHT: (C)2015,JPO&INPIT【課題】水圧を高めることなく効率的に炭酸泉を生成することができる炭酸泉生成装置を提供する。【解決手段】二酸化炭素気泡が混合された水が流れる気泡溶解流路12を有し、気泡溶解流路12は、二酸化炭素気泡を分断する少なくとも1個の絞り部14と、気泡溶解流路12の出力側端において気泡溶解流路12内の水圧に保持する圧力保持部16とを有し、気泡溶解流路12の有効径は、気泡溶解流路12を流れる水の流速vにおける気泡の粘性抵抗Rが、二酸化炭素気泡が該有効径である最大径Dである場合の二酸化炭素気泡の浮力F以上となるように定められ、絞り部14は、気泡溶解流路12よりも有効径が小さくされている。【選択図】図1
