  • a pressure generator via which, for the purpose of air bubbling, air or water and air into which water located in the bathing basin is blasted.
  • controllable path closures that close the flow path and open the flow path are installed, which, according to a specifiable working rhythm, cause the flow path (s) to be opened and / or closed.
  • a hot tub is known from EP 209646, the jet nozzles of which are equipped with closable nozzle orifices.
  • the nozzle mouth is opened by axial movement of a closure body which opens the nozzle mouth as a result of the pressure of a flowing medium and closes the nozzle mouth as a result of hydrostatic or spring force.
  • a medical bathtub which is used to carry out automatically underwater massages.
  • the massage effect is generated by a water jet.
  • a large number of single-jet nozzles is assigned a solenoid valve which is actuated by a program control device with a shift drum.

  • Valves controlled by the flowing medium have the disadvantage that a relatively high admission pressure must always be present until the valve closure opens the flow path.
  • Nozzle mouth closures that are opened by the pressure of the flowing medium are not controllable.
  • these closures have the disadvantage, when using a feed-irrigation system that is independent of the inner basin, that even at low pressure of the detergent the nozzle openings open and detergent can run into the water basin. This is particularly the case when the spring pressure and limescale decrease.
  • a certain force of the pressure generator (blower, pump) is required to effectively open the nozzle mouth against the spring.
  • the present invention has for its object to provide a water basin of the type mentioned, in which the supply of the air to be blasted is controllable and the nozzle orifice closure both at low medium pressure, for example when supplying compressed or suction air as well as at high medium pressure from the pressure generator acts, does not open or in both cases only opens at a definable point in time, and that the device causing the closure of the flow path can be produced inexpensively and is also service-friendly. It should also be ensured that the rubber-elastic parts serving as sealing and sealing surfaces are exposed over their entire surface to the flowing medium or the detergent.
