As a result, the hot water in the bathtub 18 is smoothly drained from the drain port 20C of the circulation port 20 through the drain pipe 28.

Further, in the drainage system 12, a drainage pump 66 is provided in the drainage pipe 28. As a result, by operating the drainage pump 66, the hot water in the bathtub 18 is forcibly drained from the drainage port 20C of the circulation port 20 through the drainage pipe 28. Therefore, the hot water in the bathtub 18 can be drained in a short time as compared with the case where the hot water in the bathtub is naturally drained through the circulation port and the drainage pipe.

Further, in the drainage system 12, the biological information sensor 94 includes a heart rate sensor that detects the heart rate of the bather in the bathtub 18, a human sensor that detects the position of the bather, and a blood pressure sensor that detects the blood pressure of the bather. , And at least one of the electrocardiogram sensors for detecting the electrocardiogram of the bather. The control unit 86 operates the drainage device 26 based on the bathing state of the bather based on the information detected by at least one of the heart rate sensor, the motion sensor, the blood pressure sensor, and the electrocardiogram sensor. Thereby, for example, when the heart rate and blood pressure of the bather are higher than the permissible values, or when the bather does not move, the hot water in the bathtub 18 can be drained from the drain port 20C of the circulation port 20.

The drainage system 12 is provided with a remote controller 72 in which a speaker 100 for outputting sound is arranged in the bathroom 22, and the control unit 86 receives hot water in the bathtub 18 before operating the drainage device 26.
