Definitions

  • the present invention relates to a method for operating a hydraulic device for a sanitary facility that can be used in particular for personal hygiene and/or therapeutic applications.
  • Hydraulic devices can be designed, for example, in the manner of flush-mounted fittings that can be built into a building wall. Furthermore, hydraulic devices can have a mixing valve for mixing cold water and hot water to form mixed water with a desired mixed water temperature. The mixed water can then be fed via a plurality of liquid outlets of the hydraulic device to a plurality of liquid outlets of the sanitary facility, for example an overhead shower and a hand shower. For this purpose, the liquid outlets of the hydraulic device can be connected to the liquid outlets of the sanitary facility, for example via pipelines or hose lines. The delivery of the mixed water via the liquid outlets of the hydraulic device can be controlled via valves. When the liquid delivery is switched from one liquid outlet to another liquid outlet, very high pressure surges and/or flow noises can arise from the liquid, particularly in the case of high liquid flow rates.
  • the object of the invention is therefore to at least partially solve the problems described with reference to the prior art and in particular to specify a method for operating a hydraulic device by means of which high pressure surges and/or flow noise of the liquid can be at least reduced.
  • This object is achieved with a method according to the features of the independent patent claim.
  • Further advantageous refinements of the invention are specified in the dependent claims. It should be pointed out that the features listed individually in the dependent patent claims can be combined with one another in any technologically meaningful way and define further refinements of the invention. In addition, the features specified in the claims are specified and explained in more detail in the description, with further preferred embodiments of the invention being presented.
  • a method for operating a hydraulic device for a sanitary facility contributes to this, the hydraulic device having a first liquid outlet for dispensing a liquid and a second liquid outlet for dispensing the liquid, with a volume flow of the liquid passing through during switching between the first liquid outlet and the second liquid outlet a flow regulator is reduced.
  • the sanitary facility can be a shower or bathtub, for example, which can be used in particular for personal hygiene and/or for therapeutic applications.
  • the sanitary facility can be arranged, for example, in a bathroom.
  • the sanitary facility can also be used in systems with bathing facilities, such as e.g. As saunas, whirlpools, swimming pools, etc. can be used.

  • the hydraulic device can have a housing, for example, which can consist at least partially of plastic and/or metal.
  • the hydraulic device can have at least one liquid inlet.
  • the hydraulic device can have a first liquid inlet for cold water and a second liquid inlet for hot water.

  • a supply line for example in the form of a pipeline or hose line, can be connected to the at least one liquid inlet.
  • the hydraulic device has a first liquid outlet for dispensing a liquid and a second liquid outlet for dispensing a liquid.
  • the hydraulic device can have a plurality of liquid outlets, for example two to nine liquid outlets.
  • the liquid drains can each be connectable in particular to at least one liquid outlet of the sanitary facility.
  • a liquid line can be connected to each of the liquid drains, for example in the manner of a pipeline or hose line.
  • each liquid outlet of the hydraulic device can be connected to one or more liquid outlets of the sanitary facility.
  • the liquid outlets can be connected to the at least one liquid inlet via at least one liquid channel.
  • the hydraulic device can have a carrier with at least one receptacle for a valve.
  • the carrier serves in particular to accommodate functional components of the hydraulic device.
  • the carrier can be at least partially made of plastic or metal, such as brass.
  • the carrier can be formed in the manner of a base body.
  • the at least one liquid inlet and/or the liquid outlets can be designed as an opening in the carrier.
  • the at least one liquid channel can be formed in the carrier, for example in the manner of a bore.
  • the valve can be used in particular to control liquid delivery via the liquid drains. In particular, the Liquid delivery can be controlled via a separate valve via each liquid outlet.
  • the at least one valve can be actuated, in particular, electrically.
  • this can mean that the valve can be closed and opened electrically.
  • the valve can be designed in the manner of a shut-off valve, an electromechanical valve and/or a solenoid valve.
  • the hydraulic device can have a mixing valve.
  • Cold water with a cold water temperature and hot water with a warm water temperature can be mixed to form mixed water with a desired mixed water temperature in particular by the mixing valve.

  • the volume flow is reduced with the flow regulator, by means of which the volume flow or a flow rate can be controlled, with which the liquid flows to the first liquid outlet and/or the second liquid outlet.
  • the flow regulator can be, for example, the mixing valve.
  • the liquid outlet to which the liquid delivery is to be switched is in particular only opened when the volume flow of the liquid is reduced. In this way, pressure surges and/or flow noises from the liquid when the liquid outlet is opened can be avoided.

  • the liquid line can have a Y-switch.

  • step c) the second valve for dispensing the liquid via the second liquid drain is opened.

  • the volume flow of the liquid can be reduced by 10% to 90%.
  • the volume flow of the liquid can preferably be reduced by 40% to 60 percent, particularly preferably (approximately) 50%.
