The suction port 301 is provided on the inner surface of the lower part of the bathtub 200. The first water supply pipe 302 connects the suction port 301 and the pump 303. The second water supply pipe 304 connects the pump 303 and the water discharging device 1A. The pump 303 sucks hot water W from the bathtub 200 through the first water supply pipe 302 and pumps it through the second water supply pipe 304 to the water discharging device 1A.

As shown in FIG. 3, the body 28 is divided into a horizontally long first body 30 and a horizontally long second body 40.

As shown in FIG. 4, the first body 30 has a cylindrical introduction part 31 that projects downward. A base plate 20 is interposed between the upper edge 210 of the bathtub 200 and the first body 30. The base plate 20 has a cylindrical base protrusion 21 that is fitted onto the introduction part 31 of the first body 30 , and connects the downstream side of the second water supply pipe 304 to the base protrusion 21 via the cylindrical connecting member 10 . The ends are connected. Thereby, the water supply system 300 is connected to the introduction hole 90h via the base plate 20 and the connection member 10.

The sterilizer 60 irradiates ultraviolet rays downward, that is, toward the throttle channel 92 and the discharge port 93. The wavelength of the ultraviolet light emitted by the sterilizer 60 is about 200 nm or more and 380 nm or less. This performs sterilization. Note that "sterilization" as used herein does not mean merely killing bacteria, but also includes destroying, removing, and inhibiting the proliferation of pathogenic microorganisms such as bacteria and viruses. . Therefore, "sterilization" as used herein broadly includes so-called sterilization, sterilization, sterilization, disinfection, sterilization, and the like.

A waterproof packing P is provided between the first body 30 and the second body 40. Similarly, a packing (not shown) is also provided between the sterilizer 60 and the first body 30, that is, between the irradiator cover 63 and the inner peripheral surface of the through hole 46.

Therefore, by using the sterilizer 60, the flow path 90 can be formed, and the hot water W flowing through the flow path 90 can be sterilized from close range. Therefore, sterilization can be performed efficiently. Since the sterilizer 60 constitutes a part of the wall of the flow path 90, the installation space for the sterilizer 60 can be saved.

The sterilizer 60 is an irradiator that irradiates light including ultraviolet rays. Therefore, the hot water W flowing through the flow path 90 can be irradiated with ultraviolet rays from a close distance, and sterilization can be performed efficiently.

A waterproof and UV-transparent irradiator cover 63 that covers the irradiator 62 constitutes a part of the wall of the flow path 90 . Therefore, the irradiator cover 63 can be effectively used to form a part of the wall of the flow path 90.

The sterilizer 60 constitutes a part of the wall of the throttle channel 92, which has a small channel cross-sectional area among the channels 90. Therefore, sterilization can be performed efficiently in this respect as well. The sterilizing device 60 irradiates ultraviolet rays toward the inside of the water discharging device 2A. Therefore, it is easier to set the ultraviolet rays to be stronger, that is, the wavelength of the ultraviolet rays, to be shorter than when irradiating the ultraviolet rays toward the outside.

The storage chamber 91, the throttle flow 92, and the discharge port 93 each extend in a horizontal direction that is orthogonal to the flow direction of the hot water W in the flow path 90. Therefore, the film-like hot water W can be efficiently formed.
