Definitions

  • the present invention relates to a method for controlling a shower system and a shower system.
  • a shower system regularly includes a shower head connected to a mixer tap for supplying mixed water.
  • a user activates the water in the shower system, that water is initially cold.
  • it can take seconds to minutes for warm water to come out of the shower head (overhead shower).
  • it is uncomfortable to stand directly under the initially cold water. It is therefore customary to first wait until the water has warmed up and repeatedly feel the temperature of the water - until a comfortable temperature is reached.
  • a shower head system in which a shower head can be arranged in a receptacle with a drain and a temperature sensor and a temperature display.
  • a showerhead system When the showerhead system is activated, water flows from the showerhead into the receptacle and down the drain. The temperature of the water is measured and displayed. A user can thus wait until the water has reached a desired temperature.
  • a shower head system with a mixer tap to which the shower head is connected is known. Water is fed to an outlet until a minimum temperature is reached in the mixer tap. Only when the minimum temperature is reached is the water diverted to the shower head.
  • 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 controlling a shower system and a shower system in which cold water and residual water can be removed from a shower head with at least two spray types .
  • steps b) and d different beam outputs or different combinations of beam outputs are activated.
  • steps a) to c) very particularly preferably take place at least temporarily in parallel with one another.
  • the first jet outlet is always (at least or exclusively) activated.
  • the temperature can be measured continuously or at time intervals.
  • Step c) can also be carried out immediately after step a) and before, or simultaneously with, step b).
  • Step d) is conditional and is only carried out if it was determined in step c) that the minimum temperature was reached.
  • steps a) through d) are performed in the order listed.
  • the shower head has a first jet outlet, a second jet outlet and a switching device for activating the desired jet outlet.
  • the switching device includes z. B. at least one valve through which a volume flow to the respective jet outlet, possibly also to several jet outlets can be diverted.
  • a volume flow of a liquid (in particular water) emerges from the shower system via a jet outlet and can be used by a user for showering.
  • the mixer tap is suitable for mixing cold water and hot water to mixed water with a desired mixed water temperature.
  • the mixer faucet can have a mixing valve for mixing cold water and hot water into mixed water with a desired mixed water temperature.
  • the cold water can be fed to the mixing valve in particular via a cold water line and the hot water can be fed via a hot water line.
  • the cold water can have a cold water temperature which is in particular a maximum of 25° C. (Celsius), preferably 1° C. to 25° C., particularly preferably 5° C. to 20° C.
  • the hot water can have a hot water temperature which is in particular a maximum of 90°C, preferably 25°C to 90°C, particularly preferably 55°C to 65°C.
  • the shower head is fluidically connected to the mixer tap via the connecting line, so that when the shower system is activated and depending on requirements, cold water, hot water or mixed water can be routed to the shower head.
  • the temperature sensor is used to measure and determine a temperature of the volume flow supplied to the shower head.
  • the temperature sensor can be arranged in the mixer tap, in or on the connecting line or in the shower head.
  • the shower head has a line volume in particular between the respective jet outlet and the connecting line, in which residual water can remain. This residual water is only removed from the shower head when the respective jet outlet is activated.
  • the shower system is activated in particular by switching on a volumetric flow that flows through the connecting line to the shower head. Activation is carried out regularly by a user, e.g. B. by operating the mixer tap or a control unit of the shower system.
  • the volume flow has at least initially a temperature that regularly falls below a minimum temperature.
  • the minimum temperature is in particular a temperature that is perceived as pleasant by a user, ie z. B. between 20 and 40 degrees Celsius.
  • the first jet outlet is in particular activated, so that the volume flow flows out at least or exclusively via the first jet outlet.
  • the first jet outlet can be a specific jet outlet, e.g. B. for a jet jet (few but larger openings, so that a relatively large volume flow flows out through each opening) or a rain jet (many but smaller openings, so that a relatively small volume flow flows out through each opening).
  • the jet outlet provided for a jet jet is preferably selected first. But it can also be several, z. B. all jet outlets can be selected.
  • step c) in particular, the temperature of the volume flow is measured with the temperature sensor.
  • the temperature can be measured continuously or at time intervals.
  • the selected (first) jet outlet remains activated until the volume flow has reached a minimum temperature.
  • step c) If it is determined in step c) immediately during or after activation of the shower system that the minimum temperature has been reached, it is also possible to switch or switch directly to the respective other jet outlet. However, it is preferred that step b) is always carried out first and then, if necessary, step d) a short time later (ie without carrying out step c) again).
  • step d) at least the second jet outlet is in particular activated as soon as the volume flow has reached the minimum temperature.
  • steps b) and d) in particular, beam outputs that differ from one another or combinations of beam outputs that differ from one another are activated.
  • step b) initially only the first beam output is activated and then in step d) only the second beam output is activated.
  • different beam outputs and/or different combinations of beam outputs should be activated in steps b) and d).
  • an optical and/or Provided acoustic distinguishing feature that can be detected and processed by the user sensory (that is, via his senses, such as the eyes or hearing).
  • the proposed method enables cold water to be removed from the shower system. Any remaining water is also removed, since the different jet outlets are (automatically) rinsed as a result of the process. Reaching the minimum temperature is shown in a number of ways: e.g. B. as stated acoustically and / or optically based on the selected jet outlets and possibly by a signaling device.
  • the minimum temperature can be freely determined in particular by a user.
  • the proposed solution can be integrated into an existing product with relatively little effort, so that costs can be kept low. Retrofitting by the customer is also possible.
  • the temperature sensor is arranged in the shower head.
  • the minimum temperature can be set for each activation of the shower system, in particular by a user.
  • the switching device comprises at least two solenoid valves, by means of which the first jet outlet, the second jet outlet or both jet outlets can be activated. If a jet outlet is activated, a volume flow or a partial volume flow flows out of the shower head via this jet outlet.
  • the shower system has a signaling device that can be used to generate an optical signal that at least indicates that the minimum temperature has been reached.
  • the optical signal is in particular a light signal, z. B. generated by an LED or other light source.
  • the shower system has an operating unit, through which at least the shower system can be activated and the switching device can be controlled.

  • the control unit is in particular a remote control as hardware z. B. is provided together with the shower system.
  • the remote control can also be provided as a program, so that e.g. B. via a smartphone or a tablet as hardware, the control unit can be implemented.
  • the operating unit has a signaling device that can be used to generate an optical signal that at least indicates that the minimum temperature has been reached.

  • BLE Bluetooth low energy
  • the temperature sensor and the electronics in particular go into passive operation, in which as little energy as possible is consumed.
  • the proposed shower system can be used with known components of shower systems, e.g. B. mixer taps and connecting lines, in particular combined.
  • a existing shower system can be supplemented or retrofitted with the proposed components, so that the shower system modified in this way then has the functionality described.
