Water heated by the heater is spouted from a washing nozzle. In this bidet washing the private parts, water inflow into the dead water zone lower than the heater is allowed when supplying water to uniform the pressure distribution. By keeping the stable state of a laminar state (pressure distribution) from the lower layer side water to the upper layer side warm water in the warm water storage tank, the pushing up effect is increased as much as possible, especially when supplying water, it is prevented to the utmost that the interface widening substantially horizontally as a boundary face between water and warm water is disturbed.
