DEVICE FOR RECYCLING REMAINING HOT WATER IN BATHTUB

PROBLEM TO BE SOLVED: To efficiently and simply recycle remaining water in a bathtub by providing a water feeding means for recycling remaining hot water in the bathtub or hot water as toilet washing water and a recycling means for recycling remaining hot water recovered by the water feeding means as toilet washing water after sterilizing it by a sterilizing means. SOLUTION: At the time of using, a remaining water recycling button built in a hot water supplier remote controller 52 is pressed to start recycling remaining hot water as toilet washing water. Then, when the toilet 30 is used and a water level sensor 31 detects the lowering of a water level in a low tank 32, the signal is sent to the control part of a hot water supplier 40 through a water level sensor signal line. Next, after an intra-bathtub water level sensor 44 in the hot water supplier 40 confirms that the water level is higher than a prescribed level, a three-way valve 47 is switched to drive a liquid feeding pump 48 and a sterilizer 46. Thus, remaining hot water in the bathtub 51 passes through a sucking piping 27 to the supplier 40 from the bathtub 51 by the pump 48 to be fed to a toilet tank 32 from a remaining water or clean water feeding piping 22.
