<p>PROBLEM TO BE SOLVED: To surely sterilize hot water in a bath tub for a considerably long period of time, and effectively sterilize the hot water by efficiently utilizing heat energy for heating the hot water in the bath tub to a set temperature. SOLUTION: A hot water circulation type bath tub device which is operated for 24 hours continuously, comprises a circulating pump 2 for circulating hot water in a bath tub 1, a heater 3 for heating the hot water which is circulated by the circulating pump 2, and a filter tub 4 for clearing the circulating hot water. The hot water circulation type bath tub device allows a hot water circulating path 5, through which hot water is circulated by the circulating pump 2 to be diverged into a heating path 7 and bypass 8 at a separator 10. The hot water which is separatedly circulated through the heating path 7 and the bypass 8 is re-mixed by a mixer 11 for further circulation to the bath tub 1. The heating path 7 is connected to the heater 3. The heater 3 heats the hot water to 50 deg.C or more over the heating conditions of the hot water circulated to the heating path 7. The hot water heated in the heating path 7 is mixed with the hot water which is circulated through the bypass 8 by the mixer 11, and then is circulated to the bath tub 1.</p> |
