<p>A device including a bathtub (2), injection nozzles (5) combined with supply devices (12, 20) to produce hydrodynamic jets directed into the bathtub (2), and control units (22, 25, 27) for providing synchronized control of the hydrodynamic jets from the injection nozzles (5) arranged on opposite side walls (3, 4) of said bathtub (2). The control units are arranged so that, when they direct a hydrodynamic jet upwards from one of the injection nozzles on one of the side walls of the bathtub, they simultaneously direct downwards the hydrodynamic jet coming out of an injection nozzle on the opposite side wall of said bathtub, and vice versa.</p> |
