Definitions

  • the invention is based on a hydromassage nozzle as described by US 3,297,025, US 2,738,787 and DE P 37.16 683.2.
  • Devices of this type serve to generate turbulence in water basins and in particular underwater massage.
  • hydromassage jets known in many different ways have the disadvantage that a relatively large installation space is required on the outside of the tub.
  • current-carrying electrical lines are required in the immediate vicinity of the water basin, which lead to the drive unit and supply it with electricity.
  • These supply lines and the drive unit are undesirable in the area of the water-bearing basin for safety reasons.
  • Hydromassage jets which are supplied with a radiation medium via a pipeline system, have the disadvantage that residual water quantities always remain in the pipelines, and that odor and putrefaction lead to unpleasant consequences.
  • complex devices are to be provided which serve to rinse, clean and disinfect the line systems.
  • the invention has for its object to provide a device that takes water directly from the pool interior, accelerates it by a conveyor device that can be operated reliably and safely and radiates it back into the pool interior.
  • the hydromassage nozzle according to the invention has the advantage that no supply system is required for the transport of the medium to be injected into the water basin. As a result, no facilities for rinsing, cleaning and disinfection are required.
  • the design of the conveyor is flat and requires little installation space.
  • Electric power is only indirectly required to drive the conveyor and does not have to be available in the wet area of the water basin.
  • the pressure generator can be set up centrally at a service-friendly installation location, with maintenance-free pressure lines leading to the individual hydromassage jets.
  • An open or a ge can be advantageous closed flow circuit can be used.
  • An open flow circuit has the advantage that air is used as the drive medium.
  • Another advantage is that the media from the primary and from the secondary flow circuit can be converted into one another for the purpose of mixture formation.
  • a self-contained primary flow circuit has the advantage that a medium serving to drive the secondary flow circuit and a conveying device of a small design, designed as a centrifugal or piston pump, can be used, and a circulating bath water system is not required.
  • the characteristics of claim 2 have the advantage that the primary and secondary flow circuits lead into the housing, but separate flow channels are formed for the flowing media.
  • claims 3 to 5 have the advantage that the energy applied to the primary flow circuit can be used to accelerate the medium supplied to the secondary flow circuit and converted into a conveying movement.
  • the nozzle housing is advantageously designed as an inexpensive diaphragm pump which can be driven, for example, by a piston pump in the primary flow circuit.
  • the diaphragm pump has the advantage over a rotor that hair cannot get caught.
  • claims 6 to 10 have the advantage that a turbine impeller rotatably mounted within the nozzle housing serves to transmit the flow pressure from the primary flow circuit to the secondary flow circuit and the conveying device in the secondary flow circuit is acted upon by rotary movement, whereby the transmission takes place through an axis, which can be used together with the rotors in the nozzle housing.
  • the characteristics of claim 11 have the advantage that a water-air mixture is generated by the known Venturi effect, that the Venturi nozzle is inserted in a streamlined location in the nozzle housing and the medium of the primary flow circuit is used and used as a jet.
  • the characteristics of claim 12 have the advantage that the pressurized medium can be transferred from the primary flow circuit into the secondary flow circuit and the conveying device in the secondary flow circuit can be acted upon directly with drive energy or with flow pressure, the transition mouths of the different flow channels within the nozzle housing are aerodynamically designed. Further advantages can be found in the following description of a preferred exemplary embodiment, the drawings and the claims.

  • a pump for example, serves as the pressure generator.
  • a blower is used for gaseous flow media.
  • the primary flow circuit can be filled with a medium that remains in the circuit, but it is also possible to fill the circuit with fresh water before each start-up and to empty it again after use.
  • a refill can take place via a filler neck 15 branching off from the flow circuit, which is in flow connection through a closable mouth 16 with the interior 2 of the water basin, which opens automatically, for example, when the water basin is filled, and releases the flow circuit for flooding.
  • the opening and closing can take place, for example, by means of a magnetic valve provided near the mouth.
  • a float valve is also conceivable, which is designed in such a way that the valve body is designed to float and float in a non-pressurized state when filled, or in some other way, for example spherically shaped, movable on a rolling plane formed in a valve housing, lifted off its sealing seat and in operation the pressure generator can be returned to its seat due to the operating pressure, reseals.
