Definitions

  • the invention relates to a whirlpool nozzle of the type specified in the preamble of claim 1.
  • Whirl pool jets are used in tubs or swimming pools in order to generate a sharp water jet enriched with air bubbles with high flow velocity, in particular to achieve a massage effect.
  • the known whirl pool nozzles are connected to a pressure line connected to a pump and to an air line.
  • the water is fed to the whirl pool nozzle via the pump at high pressure.
  • the nozzle tube has a lateral opening connected to the air line, through which air is entrained by the water jet according to the Venturi principle.
  • a spring-loaded valve operating in the manner of a pressure relief valve is provided, which opens at a predetermined limit pressure of the pump.
  • liquid disinfectant is added to the pressure line system.
  • the pressure line system to which the individual whirl pool nozzles are connected is closed to form a circulation circuit in which the disinfectant circulates. So that the disinfectant does not emerge from the whirl pool nozzles in a jet, these must remain closed.
  • the known whirl pool nozzles which are equipped with a pressure relief valve, it is necessary to carry out the flushing process with a low pump pressure which is below the limit pressure.
  • the pump must therefore be designed such that, in addition to the relatively high operating pressure, it can also generate a relatively low pressure which is set during the disinfection process. This requires a relatively complex pump and has the further disadvantage that the pump is operated with a high power loss at least during disinfection.
  • Another disadvantage of the known whirl pool nozzles is that all nozzles of the entire whirl pool system can only be operated synchronously and with the same intensity, since the pressure-dependent opening valves do not allow differentiation or selection.
  • the invention is based on the object of providing a whirlpool nozzle which is specified in the preamble of patent claim 1. To create a type that does not require a reduced pump pressure for disinfection and which allows a variety of possible variations of a whirlpool system.
  • the whirl pool nozzle according to the invention has a controllable metering valve which releases or blocks the passage from the pressure line to the nozzle tube to a desired extent in accordance with its respective setting.
  • This metering valve has a throttling effect, through which the pressure at which the water is supplied to the nozzle pipe can be selected at a constant pump pressure. In this way, the intensity of the jet exit at the individual whirl pool nozzles of a nozzle system consisting of several nozzles can be set individually.
  • the dosing valve can be adjusted until the shut-off is complete.
  • a whirlpool system is to be disinfected, all the whirlpool jets are set to shut off and the pressure system containing the pump is switched to a circuit.
  • the pump can then carry out the disinfection or rinsing process at full pump pressure because all the whirlpool jets are closed.
  • the pump therefore does not need the ability to work in low pressure mode. This reduces both the investment costs and the operating costs of a whirlpool system.
  • the whirl pool nozzle is equipped with a servomotor, which is preferably a stepper motor.
  • the servomotor is housed in the nozzle housing and it is expediently operated at low voltage in order not to cause any danger to persons in the event of a leak. All components of the whirl pool nozzle are accommodated in a common nozzle housing, which can be sealingly mounted in a wall opening of a tub or a swimming pool.
  • This nozzle housing preferably consists of a housing body which is only open at one end and into which the various components can be introduced from the open end.
  • a plug-in device can be attached to the end wall forming the closed end, which engages with a plug-in device provided on the servomotor and automatically establishes electrical contact with the servomotor during assembly.
  • the necessary control and supply lines, which are connected to the plug device on the housing side, run through the end wall.
  • FIG. 1 shows a longitudinal section through a first exemplary embodiment of the whirlpool nozzle
  • FIG. 2 shows a schematic representation of a whirlpool system with disinfection rinsing
  • FIG. 3 shows a longitudinal section through a second exemplary embodiment of the whirl pool nozzle in the open state and Fig. 4, the whirlpool nozzle of Fig. 3 in the locked state.

  • a clamping ring 13 is screwed onto a thread of the housing body 10 and presses against the edge of the wall opening from the rear.
  • a seal (not shown) is provided which is compressed when tightening the clamping ring 13 and seals the wall opening.
  • the housing body 10 contains a bore with a bore section 14a of larger diameter in the vicinity of the open housing end and a bore section 14b of smaller diameter in the vicinity of the end wall 11.

  • the cavity of the valve body 76 which is open at the front end and closed at the rear end has an opening 92 on the circumference, which can be brought into line with the air line 109 passing through the insert body 65a.
  • the air line 109 contains a spring-loaded check valve 110, the ball of which is pressed against the edge of an air inlet opening 111 of the housing body 60.
  • the opening 92 forms an air metering valve 112 together with the air line 109.
  • the whirlpool nozzle according to FIGS. 3 and 4 works as follows:
  • the servomotor 84 has withdrawn the valve body 76 from the nozzle tube 66, so that the metering valve 83 is completely open.
  • the water flow entrains air out of the valve body 76 as a result of the Venturi effect. This air mixes in fine bubbles with the water jet.
  • the check valve 110 is opened by the vacuum created inside the valve body 76, so that ambient air can flow in again.
  • the servomotor 84 has advanced the valve body 76 so far that the annular shoulder 79 abuts the valve seat 78 and the metering valve 83 is completely closed.
  • the air metering valve 112 is also completely shut off because the opening 92 is no longer connected to the air line 109. So no water flows through the whirlpool and the air supply is also shut off.
  • the check valve 110 closes by itself and blocks the air line 109 from the outside. The check valve 110 prevents water from flowing out through the air line, for example when the front end of the nozzle tube 66 is blocked.
  • valve body 76 As can be seen from FIG. 4, a slight retraction of the valve body 76 leads to the water metering valve 83 being partially opened, while the air metering valve 112 still remains closed. This enables an air-free nozzle flow. The user can therefore generate an aerated or an air-free water flow either by actuating the actuator 84 and moving the valve body 76.
  • An advantage of the embodiment according to FIGS. 3 and 4 is that the air is sucked in directly from the environment of the nozzle body and that no air line 26 connecting the whirl pool nozzles as in FIG. 2 is required. 2, the valve 50 must be closed if air-free operation of the whirl pool nozzles is desired, in the embodiment according to FIGS. 3 and 4 an air-free operation can be achieved by corresponding actuation of the servomotor 84.
  • the individual whirlpool jets can be individually set to air-free or ventilated operation.
