Abstract: According to one aspect of the invention, there is provided a bathtub device including a bathtub 2, a jetting unit 3, a jetting driving unit 4, and a controller 5. The bathtub includes a first bathtub wall surface and a second bathtub wall surface opposed to the first bathtub wall surface. The jetting unit is provided in the second bathtub wall surface and configured to jet a jet flow to a sole of a bather bathing in the bathtub. The jetting driving unit is connected to the jetting unit and configured to adjust jetting flow rate of the jet flow jetted from the jetting unit. The controller is configured to control the jetting driving unit. The controller is configured to control the jetting driving unit to cause the jetting unit to intermittently jet the jet flow with a strength, a leg of the bather being passively bent by the jet flow with the strength.

Abstract: A sanitary washing apparatus having a bidet washing function for jetting water at private parts of a female user, the apparatus includes: a nozzle including a jetting port configured to jet water; a swirling chamber and a communication channel for jetting water as a hollow-conic-shape liquid film flow at the private parts of the female user from the jetting port; and a fluid squiring device for generating an intermittent granular flow of granular water balls so as to fill inside the liquid film before the liquid film flow impinges on the private parts.
