Definitions

  • the invention relates to a sanitary fitting for dispensing tap water and treated water.
  • So-called multifunction fittings are known from the prior art, which can donate not only simple tap water, but also, for example, treated water such as chilled or carbonated water (sparkling water).
  • the object of the invention is to be able to provide a sanitary fitting that allows for more convenient operation.
  • the sanitary fitting according to the invention is initially such a multifunction fitting that the delivery of Tap water and treated water that is treated in at least one type of treatment allows.
  • the type of treatment can be, for example, the following treatments of the water:
  • the water can have been treated, for example, by filtering.
  • the multifunction faucet can optionally also provide boiling water, for example to prepare tea or other hot drinks or to provide boiling water for cooking processes and the preparation of food.
  • a typical application that requires small amounts of hot water is pouring tomatoes over them in order to skin them.
  • the multifunction fitting can also provide chilled and/or carbonated water. In the case of sparkling water, it can be advantageous to serve it chilled, so that the multifunction fitting can, for example, couple a carbonator with a cooling device, which can also be integrated as a structural unit. The water is then cooled, for example, and then carbonated if necessary.
  • a type of treatment can also be considered in which the taste of the water is changed, for example by adding flavorings.
  • other types of processing are also conceivable and are not limited to the aforementioned ones.
  • a sanitary fitting according to the invention can provide at least one or a selection of different types of treatment.
  • a carbonator for generating carbonated water or sparkling water in particular a carbonator of a cooling device can be connected downstream, because sparkling water is usually served cold and / or
  • the sanitary fitting according to the invention also has a control unit for controlling the respective water flow, both the tap water and the treated water.
  • a control within the meaning of the invention means a control and/or regulation. Control is carried out, for example, by sensory detection to check the physical parameters such as temperature, whereby if a parameter is not within a previously determined value range, a control signal or no control signal is returned to the assembly to be controlled in order to determine the properties of the to change the water to be dispensed in turn.
  • a mechanical control unit can be controlled so that the hot water pipe is opened more when the temperature is too low, while it is in turn closed more and more when the temperature rises and the specified parameter is exceeded.
  • control unit can also be provided, each for the warm and/or cold and/or mixed tap water and for the treated water.
  • the control unit can in principle also be designed as an overall control unit for tap water or for treated water.
  • the control unit can be divided into sub-control units.
  • the sanitary fitting according to the invention is characterized in particular by the fact that it can be operated easily and conveniently, although it is designed as a multifunctional fitting and offers a large number of output options that go well beyond setting the water volume.
  • a contactless operation has the particular advantage that it can satisfy the highest hygiene requirements because the fitting does not have to be touched. Especially when preparing food, it often happens that the operator / chef has food marks on his hands, and these
  • a control signal is basically understood as information that the operating unit forwards to the control unit.
  • This control signal can be a purely mechanical signal, such as a rotation through a certain angle, a translational movement, a screwing movement or the like.
  • the control signal can also be an electrical signal (digital or analog), an optical signal (e.g. an infrared signal) or some other electromagnetic signal, a change in magnetic field or a combination of any signals.
  • the information content can also be freely selected and can contain, for example: water volume per unit of time, temperature, type of treatment, mixing ratio, etc.
  • the operating logic that can be carried out with the control signal can generally also be freely defined, possibly also reprogrammed and adapted to the conditions of the water inflow .
  • both water flows namely the water flow for simple tap water and the water flow for treated water
  • the flow of water Treated water can also in turn be divided into several water flows or include several (parallel connected) water flows if the faucet allows water to be dispensed after several types of treatment.
  • a water flow is branched off that is also only operated purely mechanically, e.g. the mains water control element for mixing warm and cold water.
  • the non-contact operating unit can work in different ways. It basically includes a sensor that makes it possible to perceive processes in which the fitting is not touched and which can then be interpreted as commands and forwarded to the control unit as control signals.
  • a sensor that makes it possible to perceive processes in which the fitting is not touched and which can then be interpreted as commands and forwarded to the control unit as control signals.
  • an infrared sensor can be used for this. Due to the thermal radiation emanating from the operator, the sensor reacts accordingly when the operator is at a certain distance or closer to the sensor.
  • acoustic sensors in particular voice recognition units, can also be used, which react to noises (for example clapping noises, whistles or the like) or include a voice recognition unit which understands and implements specific voice commands.
  • Speech recognition usually offers the advantage that the commands can be recognized and implemented very precisely.
  • the operator can say the command he wants to give directly and does not have to remember any codes, for example "clap once" to turn on the water flow, " clap twice" to turn off the water flow. It is therefore also fundamentally easier with voice control to be able to implement a basically unlimited number of multifunction options.
  • optical sensors can also be used in an advantageous manner, for example distance sensors such as time-of-flight sensors (TOF sensors). These can determine the distance between the operator and the sensor, so that this function can also be used for operating purposes. It is also possible to distinguish whether a person is just by chance in the vicinity of the faucet or actually wants to operate it.

  • the sanitary fitting also includes an operating unit for manual operation that can be operated by touch, with which control signals can be generated and passed on to the control unit.
  • an operating unit can be, for example , a rotary knob or a one-handed lever or some other mechanical operating device that converts a mechanical gesture into a mechanical actuating process. It is also conceivable that touching the device triggers a mechanical process, which in turn is recorded by an electronic sensor that forwards the operating signal. It is then a mechatronic and not a purely mechanical operating unit.
  • Such additional one-touch control panel can offer several advantages:
  • the operating unit that can be operated by touch can be used to still be able to operate the fitting, even if operation via the touchless operating unit is not possible at the moment.
  • This does not necessarily have to be a technical defect. It is conceivable, for example, that an optical sensor is blocked because, for example, when food is being prepared it is covered with residues of sauce and its sensory function is thus impaired. If the operator has overlooked this circumstance or just does not have the opportunity to clean the sensor effectively, there is still the possibility of manual operation.

  • the sanitary fitting can initially have a common delivery line for mains water and treated water. The delivery line leads directly to the outlet of the sanitary fitting.
