PROBLEM TO BE SOLVED: To shorten a hot water passage, to reduce a heat loss, to heat and remove the residual water in a nozzle main body with a heater after washing and to prevent the propagation of bacteria by buidling the instantaneous heating type heater in the private parts washing nozzle main body. SOLUTION: This bidet is provided with a selector valve 45 on a feed water path 44 to be used for anus washing and bidet washing. The feed water path 44 is provided with an instantaneous heating type heater 28 and temperature detectors 27a, 27b in the front and rear of it, and an electronic control device 40 compares the detected water temperature with the set temperature and controls the carrying current of the heater 28. Electromagnetic induction heating by a fluororesin-coated Nichrome wire of a heating coil is used for the heater 28. When private parts washing is completed, the residual water in the feed water path 44 is removed via the heating by the heater 28, the removal of the residual water is confirmed by the rise of the detected temperature, and the heating of the heater 28 is stopped. A passage of the heated hot water is shortened, a heat loss is reduced, the residual water is removed, and the propagation of bacteria can be prevented. |
