 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 to 3. First, the bathtub 1 will be described. As shown in FIGS. 2 and 3, this bathtub 1 integrally includes a bathtub body 2 and a water heater 3, and the water intake port 4 and the hot water outlet 5 from the water heater 3 are the same as those of the bathtub body 2. It opens to the inner wall surface 2a on the side surface. A water faucet 6 that faces the interior of the bathtub body 2 from above is provided at the top of the bathtub 1.

Next, the bath water purifier 11 will be described. Reference numeral 12 is a hollow case, and this hollow case 12 comprises a mounting base 13 and a cover 14, as shown in detail in FIG. A flange 16 is vertically integrally provided on one end of a cylindrical portion 15 of the mounting base 13, and mounting holes 17 are formed on both sides of the flange 16, respectively. Then, the pair of suction cups 18 are attached to the flange 16 on the opposite side of the cylindrical portion 15 through these attachment holes 17. That is, the necked projections 19 provided on the suction cups 18 are inserted into the mounting holes 17 to attach the suction cups 18 to the flange 16. Both suction cups 18 are for detachably attaching the hollow case 12 to the inner wall surface 2a of the bath body 2.

The hollow case 12 containing the cleaning agent 31 is attached to the inner wall surface 2a of the bath body 2 by the suction cup 18. At this time, the position of the hollow case 12 is such that the inflow port 21 faces the tap hole 5 that opens to the inner wall surface 2a of the bath body 2. Then, when boiling the bath, first, water W is poured into the bathtub main body 2 from the faucet 6. Then, when the water heater 3 is driven, the water W in the bathtub body 2 is taken into the water heater 3 from the water intake port 4 and heated there, as shown by the arrows in FIGS. 2 and 3. Further, it returns from the tap opening 5 into the bathtub body 2. Such circulating heating raises the temperature of the water W in the bath body 2. By the way, the water W discharged from the outlet 5 flows into the hollow case 12 from the inflow port 21, passes through the purifying agent 31, and exits from the outflow port 24 into the bath body 2. Then, while passing through the cleaning agent 31, chlorine and odor contained in the water W are adsorbed by the activated carbon 33, and the water W is purified.

Thus, by removing chlorine from the water W in the bath body 2 before taking a bath, the skin does not feel uncomfortable even when the bath is first boiled. At the same time, it is safe because harmful chlorine is not ingested by the human body.

The purifying agent 31 made of the activated carbon 33 needs to be replaced about once every three months. When the purifying agent 31 is replaced, the cover 14 is first removed from the mounting base 13. At this time, the cover 14 or the cylindrical portion 15 of the mounting base 13 is elastically deformed, and the engagement protrusion 23 of the cover 14 is disengaged from the stopper portion 22 of the cylindrical portion 15. Then, the old purifying agent 31 is taken out from the cylindrical portion 15 and the new purifying agent 31 is put into the cylindrical portion 15.
