PROBLEM TO BE SOLVED: To lessen the danger that gaseous ozone incurs on a bathing person by building a recovering means for recovering the excess unreacted gaseous ozone emerging on bath water and an ozone cracking means for cracking the recovered ozone into a bath water circulating device. SOLUTION: The bath water circulating device 2 is internally provided with a bath water circulating pump 3 and a purifying cylinder 4. The bath water is returned from a bath water suction port 5 through the purifying cylinder 4 into a bathtub 1 from a bath water blow-off port 6. This bath water circulating device 2 is internally provided with an ozone generator 8 consisting of an air pump 8.1, a solenoid valve 8.2, an ozone generator 8.3, a check valve 8.4 and an ejector 8.5 for injecting the gaseous ozone. The generated gaseous ozone is mixed into the bath water by the ejector 8.5. A pump 7.1 as the ozone recovering means and an active carbon filter 7.2 as the ozone cracking means are installed in the bath water circulating device 2 so that the air in the bath water is sucked by the pump 7.1 and the ozone in the air is cracked by the active carbon filter 7.2 and is then released into the atmosphere. |
