  • the short-term heating up at least 70 ° C is provided here to reduce the germ and bacteria in shower water.
  • the shower water is mixed via a mixing valve in front of the outlet nozzle of the shower with tap water.
  • a showering time of about 20 seconds can be expected at a flow rate of 5.5 l / min and a water temperature of 37 ° C. After this showering time then the water temperature gradually decreases.
  • a longer shower time would be possible with a larger hot water tank and a correspondingly higher energy consumption per se.
  • a larger water tank is not possible or at least undesirable for reasons of space. Even a much higher energy consumption should be avoided.
  • the invention has for its object to provide an operating method according to the preamble of claim 1, which allows a longer shower time with hot water.
  • the object is achieved in a generic method in that the device has an energy storage, with which the power range for the provision of shower water is expandable, and in that the device is switched after use in a sleep state and monitored for use is loaded and after detecting a user before dispensing shower water, the energy storage or charged after a shower operation of the energy storage and then the device is switched to sleep mode.
  • the device thus has an energy store, with which the power range for the provision of shower water is extended. In this energy storage a certain amount of energy is cached. This energy storage is available during the shower process as an additional source of energy for the treatment of the shower water.
  • the energy storage supplements, for example, a water heater.
  • the water heater can then be fed during the shower process with the available power, for example, a connected power grid.
  • the water of the water heater can then be mixed, for example, with the water of a hot water tank, which forms the energy storage.
  • This hot water tank can be maintained at a higher temperature of, for example, higher than 40 ° C and lower than 90 ° C.
  • a shower time of one minute at a flow rate of 5.5 I / min and a shower temperature of 37 ° C is possible.
  • an energy storage in the form of a hot water tank for example, an energy storage in the form of an electrical, electrochemical or chemical energy storage is conceivable.
  • the energy storage could for example be an accumulator, which is connected to an electrical network and increases its power during the shower process. After a shower process, the accumulator is then recharged via the mains.
  • energy storage in which a chemical or electrochemical process in case of need emits energy are also possible.
  • the energy store is a high-temperature store, in which water can be provided with a temperature which is higher than the temperature of body-warm water.
  • the intended temperature of the high-temperature reservoir is preferably in the range of about 40 ° C to 90 ° C.
  • the temperature is then lowered to a body-compatible temperature of, for example, 37 ° C.
  • the line arrangement is made for the line arrangement to have a water circuit which can be connected to the subshower such that unheated water and water heated by a second line branch can be supplied via a first line branch of the subshower.
  • the heated water and the unheated water can be mixed in front of it or in the shower arm so that body-warm shower water leaves the shower arm. Not that one heated water can also be used to extend the shower arm and thus as a drive.
  • the first line branch is connected to a water heater.
  • a hot water tank is preferably arranged according to a development of the invention in the second line branch, which is connected via a switching valve with the first line branch.
  • the water heated in the water heater can then be supplied to the hot water tank, which at the same time emits hot water, which is mixed with water from the first pipe branch. This enables a particularly energy-saving operation. In general, a longer shower time without significant increase in the required energy is possible.
  • the device in the sleep state at rest and to be monitored with regard to a user. If a user is detected, the sleep state is canceled and the energy storage device can be charged before dispensing shower water.
  • the shower water In the case of a hot water tank in this the shower water is heated or brought to a higher temperature.
  • the power supply can be done here for example via an electrical network.
  • the heating system can work under full load. During the showering process, a controlled mixing of storage water from the hot water tank and water from the instantaneous water heater preferably takes place here. The heating system can continue to work under full load. It is also conceivable here an admixing of water that was not previously heated.
  • the energy storage device is a rechargeable battery
  • it will be discharged during the showering process so that the power of the network is supported by the power of the rechargeable battery.
  • the water is heated, for example, exclusively in a water heater.
  • a longer shower time can thus be achieved with the same network performance, since energy is supplied from the battery.
  • the energy storage is recharged.
  • the water temperature can be increased in this and kept at a certain temperature by means of a thermostat.
  • this is again charged via the network.
  • a design with multiple energy storage such as a hot water tank and an accumulator.
