Definitions

  • the invention relates to a water supply system with a device for delivering and/or distributing a water volume flow, the device being a hand shower, with an outlet opening formed in the hand shower, with an adjustable flow body, with a connection designed for water supply, with the connection being connected to the outlet opening via a channel, with an electronic water volume flow control unit and with a hand shower holder.
  • Devices for delivering and/or distributing a volume flow of water which have one or more showers, for example a hand shower, an overhead shower—also called a shower head or overhead shower—and/or a side shower are known in many different designs.
  • a shower or device for delivering and/or distributing a volume flow of water is or can be arranged at a height that is suitable for a user of the device, so that he can clean his body with a water volume jet emerging from the shower, in particular in the form of artificial sprinkling.
  • An outlet opening arranged in the shower head is designed to form a liquid jet resulting from the water volume jet.
  • the shower head can be held by the user, for example, as a hand shower, or as a ceiling shower head by holding means attached to a room ceiling or as a wall or side shower head.
  • the ceiling or wall is part of a wet room.
  • Under wet cell is a space with understood at least partially water-impermeable room walls and a waterproof prepared floor, wherein the floor of the wet room can be formed from a shower tray, a bathtub or a water-impermeable floor covering and typically contains a drain.
  • a water line connected to a water volume flow control unit for example in the form of a hose, is connected to a connection of the shower head, the connection being fluidically connected to the outlet opening via a channel in the housing of the shower head.
  • external control elements are usually used to control the water volume flow control unit, which are attached to one of the walls of the wet room, in particular below the outlet opening.
  • these operating elements are usually also wetted with water and, with increasing use, become soiled by soap residues and deposits, in particular due to the precipitation of calcium carbonate on the surfaces. In particular, said deposits are perceived as unsightly on the typically chrome-plated surfaces of the control elements.
  • the environment in particular wall sections of the room wall or the room walls below the outlet opening of the shower, is also wetted during use of the shower and soiled by deposits. Cleaning the soiled operating elements and the relevant wall sections is often laborious and time-consuming. The protruding operating element arranged on the room wall makes cleaning the room wall even more difficult.
  • a user also has to bend down to actuate the operating element if it is arranged at a low level, for example close to the edge of a bathtub, which is sometimes perceived as uncomfortable by users.
  • one-handed operation for example setting a temperature, is made more difficult during the showering process if the shower head is designed as a hand shower and the user does not want to or cannot let go of the shower head.
  • the EP 1 323 872 A1 discloses a water control module that monitors the water discharge temperature of a shower and receives user input commands.
  • the water discharge temperature is controlled by receiving user inputs via a user interface, by detecting the current water temperature in a supply pipe and by processing the user inputs and the detected water temperature.
  • a water temperature control unit for remotely controlling water temperature in a shower, which is attached to a liquid valve of a shower to adjust a temperature of water discharged from the liquid valve.
  • a showerhead is connected to the shower's liquid valve and is in wireless electrical communication with the control unit to remotely control the temperature of the water.
  • a device for monitoring and displaying the flow of water in a shower which can be installed between a shower arm and a shower head.
  • the device offers the user various forms of feedback to motivate them to save water.
  • the object of the invention is to provide a water supply system with a device for delivering and/or distributing a water volume flow, with which the operation of a water volume flow control unit can be improved and/or cleaning of the area around the device is simplified.
  • the water supply system according to the invention is characterized in that an electrical control element is arranged in the hand shower, the control element being prepared for the signaling connection to the water volume flow control unit, and the hand shower holder being prepared for determining the location and/or position of the hand shower.
  • the invention is based on the consideration that the integration of the operating element in the hand shower simplifies the operation of a water volume flow control unit and cleaning of the surroundings of a device for dispensing and/or distributing a water volume flow.
  • the integration of the control element in the hand shower makes it possible to dispense with a control element attached to a room wall below the outlet opening and the user can carry out the operation in a more comfortable position, in particular in an upright position.
  • the cleaning of a control element attached to the wall of the room can be omitted and the cleaning of the environment can be simplified since the elimination of a control element attached to the wall of the room results in a larger continuous surface of the relevant wall of the wet room. This can be cleaned correspondingly more easily, for example using a water squeegee with a rubber lip.
  • control element in the hand shower.
  • a user moves towards a control element that may be mounted relatively low on a wall of a shower cubicle must bend to make an adjustment of water volume flow parameters, in particular a release and / or stopping the water volume flow.
  • the electric control element can be supplied with electricity via an electric line with the electric water volume flow control unit.
  • the signal connection between the operating element and the water volume flow control unit can be designed as a signal line or a radio-based connection.
  • the control element in the hand shower has at least one haptic element for operating the water volume flow control unit, which sends a control signal to the water volume flow control unit when a user actuates it, causing it to start or stop a water volume flow according to the control signal.
  • the hand shower and/or the water volume flow control unit preferably have a relay and/or a voltage measuring device, the relay or the voltage measuring device automatically triggering an interruption of the water volume flow when the voltage falls below a nominal value.
  • the water volume flow control unit can have at least one spring-loaded water valve, for example.
  • the water volume flow can preferably be selected in the form of a single water jet or in the form of a large number of water jets from the outlet opening of the hand shower.
  • the temperature of the water volume flow can be set using the electric control element of the hand shower.
  • the operating element can be arranged on a surface of the hand shower that is opposite the outlet opening.
  • the opposite surface of the hand shower for example, a Understood surface that is not wetted when using the hand shower, in which the surface of the outlet opening of the hand shower is aligned orthogonally to gravity.
  • the arrangement of the control element on the surface of the hand shower housing opposite the outlet opening simplifies one-handed operation of the control panel and thus increases the comfort for the user of the hand shower. For example, a user can place an operating handle of the hand shower between the palm of the hand and the fingers of one hand and comfortably actuate the control element with the opposing thumb.
  • the operating element can also be arranged on a lateral surface of the hand shower, preferably lying essentially orthogonally to the outlet opening, for example on a circumferential surface of an essentially cylindrical housing section of the hand shower.

  • Adjusting the flow body can influence, for example, the decay length of the water volume flow emerging from the hand shower and the decay ranges of dripping, rippling or atomizing.
  • the flow body can be designed in such a way that the amount of air added is also influenced by the position of the flow body.
  • a further actuator can be arranged in the hand shower, which also reacts to control signals from the control element. This enables the user to conveniently select the jet shape and/or the air admixture with one hand.
  • a display means can be arranged in the hand shower and designed to display a water volume flow parameter and/or a temperature of the water volume flow.
  • the display means is preferably accommodated in the housing of the hand shower in such a way that when the user holds the hand shower, the display element can be seen and read easily.
  • the required information is provided by the water volume flow control unit connected to the control element and is transmitted to the display means via the connection to the control element.
  • the display of the water flow temperature is advantageous because a Nurse as the user of the device would like to guide the hand shower with one hand and support the person in need with the other hand and therefore does not have a free hand to carefully feel the water volume flow parameters and / or the temperature of the exiting water volume flow.
  • Showering with a water temperature that is perceived as uncomfortable or even damage to the skin caused by heat or hypothermia of the person in need of help can be avoided, in particular since the shower can only be started after a comfortable or permissible temperature range has been reached.
  • Water flowing out of the hand shower the temperature of which is not within the desired temperature range, can be used for other purposes or drained into a drain.

  • the acceleration sensor is arranged inside the hand shower and is designed, for example, as a piezoelectric acceleration sensor or microelectromechanical system.
  • the acceleration sensor is supplied with energy via the voltage source or via a separate electrical line.
  • a user of the device By integrating an acceleration sensor in the hand shower, a user of the device, especially when supporting and guiding a person in need of care with one hand, can accelerate the hand shower with a jerky movement in such a way that a predetermined or predeterminable threshold value of a permissible acceleration of the hand shower is exceeded and the acceleration sensor sends a signal to interrupt the water volume flow and/or a signal to start the water volume flow and/or a signal to switch to another shower, for example from a hand shower to an overhead shower or vice versa, to the water volume flow control unit or an actuator (e.g. three-way valve).
  • the predefinable threshold value can be selected in such a way that the vibrations induced by the water volume flow do not lead to the acceleration sensor responding.
  • the water volume flow is interrupted by the acceleration sensor if the hand shower slips away from the user and falls towards the floor of the wet cell with gravity. This reliably prevents water from escaping through the outlet opening of the hand shower in an uncontrolled and undirected manner after the hand shower has slipped.

  • An overhead shower is understood to be a shower that is fixed in or on a room wall or the ceiling of the wet room and allows a user of the wet room to be sprinkled artificially from above, so that the user can comfortably have the overhead shower arranged above him completely artificially sprinkled. However, if the user would like to be partially artificially sprinkled, for example if cleaning a long head of hair is undesirable, cleaning can be carried out using the hand shower.

  • the water supply system shown thus includes a device 1 with a hand shower 2 and optionally another shower 5, as well as an electronic water volume flow control unit 3 and a hand shower holder 7, which is provided for storing the hand shower 2.
  • the water volume flow control unit 3 is connected to the actuating means 24 via a supply line 6 and is thus set up to supply water to the hand shower 2 and the further shower head 5 .
  • the supply line 6.1 is coupled to the hose 9, which is coupled to the channel 8 of the hand shower 2, from a surface of a room wall of the wet room.
  • the supply line 6.1 to Hand shower 2 or the supply line 6.2 to the other shower 5 with the output line (port 6) of the water volume flow control unit 3 connected.
  • a water flow turbine 13 integrated in the output line 6 converts part of the exergy contained in the water volume flow into electrical energy by means of a generator 13.1, the generator serving to charge the voltage source 18 of the hand shower 2.
  • the energy converted by the water flow turbine 13 and the generator 13.1 is stored in an intermediate store 13.2.
  • the buffer store is connected to the hand shower holder 7 via an electrical line, so that the buffer store 13.2 serves as a voltage source for the charging electronics 11 of the hand shower holder.
  • the in the Figures 4a and 4b outlined hand shower holder 7 includes charging electronics 11, which is provided for charging the voltage source 18 of the hand shower 2.
  • the charging electronics 11 contain an oscillator 11.1 and a coil 11.2.
  • the charging electronics 11 are supplied with power via an electrical connection to the electrical water volume flow control unit 3. If the hand shower 2 is mounted in the hand shower holder 7, there is an electrical coupling between the charging electronics 20 of the hand shower 2 and the charging electronics 11 of the hand shower holder 7, so that the voltage source 18 is charged. While the hand shower 2 is being stored in the hand shower holder 7, the hand shower holder 7 sends a coupling signal to the water volume flow control unit 3, which interrupts or prevents water delivery as long as it receives the coupling signal.
  • the flow cross section of the valve 3.1 (cf. 3 ) of the water volume flow control unit 3 continuously adjustable.
  • a mixing chamber 3.2 which is designed for mixing a cold and hot water volume flow, is arranged upstream of the valve 3.1.
  • the flow cross sections of the inlet valves 3.3 and 3.4, which open a cold and hot water line or lock and thus influence a cold and hot water volume flow flowing to the water volume flow control unit 3 are also infinitely adjustable and enable precise adjustment of the ratio of the cold to hot water volume flow, so that the temperature of the water volume flow emerging from the mixing chamber 3.2 can be adapted to the wishes and needs of the user.
  • a temperature measuring device 3.5 arranged at the outlet of the mixing chamber 3.2 determines the temperature of the water volume flow emerging from the mixing chamber 3.2 resulting from the mixture of the cold and hot water volume flow and transmits a corresponding temperature signal to the water volume flow control unit 3. Any deviations between the temperature of the water volume flow determined and the temperature requested by the user after the mixture is corrected by the water volume flow control unit 3 automatically by adjusting the ratio of cold to hot water volume flow.
  • a transmitter arranged in the temperature measuring device 3.5 transmits the temperature information to the display means 16.
  • a in 3 Outlined drain valve 15 has an actuator 15 .
  • the water volume flow control unit 3 interprets the request signal received from the operating element 10 and forwards it to the drain valve 15, whereupon the actuator 15.1 opens or closes the drain valve 15.
  • the drain valve 15 is mounted on a floor drain opening of a bathtub (not shown).
  • Water volume flow parameters and/or water temperature values preferred or specified by one or more users are saved as data records in a memory unit 3.6 of the water volume flow control unit 3.
  • the user operates the operating element 10, whereupon the water volume flow control unit 3 reads the data set from the memory unit 3.6 and makes the appropriate settings. Do the settings not affect those in the water volume flow control unit 3 integrated devices, but the devices integrated in the hand shower 2, in particular the position of the actuating means 24 and the position of the flow body 14.1, the water volume flow control unit 3 sends a control signal to the operating element 10, which makes the necessary changes.
  • the sensor means 25 integrated in the hand shower holder 7 is designed, for example, as a Hall sensor and comprises a doped semiconductor layer with four electrodes and a permanent magnet designed to influence the magnetic field. If the resulting voltage of the sensor means 25 exceeds a defined threshold value, the sensor means 25 sends a signal to the water volume flow control unit 3 to interrupt an active water volume flow or to prevent a water volume flow from starting.
  • the threshold value corresponds to the voltage that results from the change in the magnetic field due to the mounting of the hand shower 2 in the hand shower holder 7, minus a tolerance value that takes into account any environmental influences, for example non-magnetic deposits.
  • the sensor means 25 send a signal to the water volume flow control unit 3 until the voltage of the sensor means 25 has fallen below this threshold value, as is the case, for example, after the hand shower 2 has been removed from the hand shower holder 7 .
