PURPOSE:To enlarge the clarifying area of a clarifying device and enhance clarification efficiency by fitting an internal tub with a void layer, removably in a water-tight external tub to fill the void layer with a clarifying member and by setting a hot water circulating device for circulating hot water in a bathtub, forcibly through the clarifying member. CONSTITUTION:An internal tub 2 is removably fitted in an external tub 1 through the released upper surface of the tub 1, and a clarifying member 7 is contained in a void layer 6 and consists of a filtering member 8 and an active stone namely granite porphyry 9. A pump 20 and a heater 21 are built in a hot water circulating device C, and when the device C is operated, then by the rotation of the pump 20, hot water in a bathtub B flows to the void layer 6 through the void of the internal tub 2, and is filtered through the filtering member 8 and the granite porphyry 9, and polluted substance in the hot water is adsorbed to be separated from, and the hot water is clarified, and is absorbed to the hot water circulating device C through a return pipe 14. The clarified hot water is heated at a proper temperature in the device C, and is pressure-fed into the internal tub 2 of the bathtub B through a through pipe 12 from a jet port 17. The maintenance of the replacement, cleaning, or the like of the filtering member 8 and said stone is performed by removing the internal tub 2 upward. |
