When a human body is washed, wash water is jetted from a posterior nozzle and a bidet nozzle to a face of the human body to be washed. While when a human body is not washed, the posterior nozzle and bidet nozzle are washed by a nozzle-washing nozzle at a high temperature. When a hygiene washing apparatus is detected not being used, the nozzle-washing nozzle is permitted by a control section to wash the posterior nozzle and bidet nozzle. After the washing operation is completed, the completion is informed by a notice lamp and a speaker. A scaling prevention substance-supplying device is provided in a piping on the upstream side of a flash-heating device of the nozzle-washing nozzle. |
