Definitions

  • the invention relates to a water fitting system with the features of the preamble of claim 1, a method for calibrating a water fitting system with the features of claim 12, a method for controlling a water fitting system with the features of claim 14 and a computer program with the features of claim 15.
  • Known water faucet systems are used in the sanitary area to enable a bathing experience that is as pleasant and pleasant as possible.
  • Bathing can refer to the entire body of the bather, such as in a full bath, or to individual body parts to be bathed, such as in a foot bath.
  • a water tank is filled with water when bathing and the bathing person is completely or partially immersed in the water.
  • the bathing experience can be made particularly appealing by various measures, such as varying or adjusting the temperature or the water flow or generating artificial water movements.
  • the object of the invention is to further develop a water fitting system known from the prior art in such a way that both economical and precise regulation of both the water temperature and the water level in the water tank is made possible. This opens up a wide range of options for designing the bathing experience for both footbaths and large bathtubs, and entire water choreographies can be realized.
  • a sensor could also be attached to the water tank, which indicates when a certain fill level has been reached.
  • the water outlet valve flows out, the mere restriction to such a level alarm sensor can only lead to completely stopping the fresh water supply when this level is reached until a correspondingly lower level is reached.
  • the fresh water inflow must never be completely switched off in the solution according to the invention. Rather, the inflow can simply be set to a continuous value known according to the calibration information. This not only makes it possible to dispense with the use of such sensors, that is to say additional components, but also makes the inflow and outflow behavior more pleasant for bathing.
  • the fresh water valve and / or the water outlet valve can be controlled manually by the user, the electrical control unit taking over the proposed control of the fresh water valve or water outlet valve which is not manually controlled in each case.
  • the user can manually control the fresh water valve and the water outlet valve as desired, without the fill level changing.
  • the preferred embodiment according to subclaim 3 describes a calibration routine as the initial calibration process, the water inlet quantity flowing for the desired fill level first being measured and then the run-out time being determined after the water outlet valve has been opened. This is a particularly simple way to determine all the desired parameters.
  • the outlet behavior through the water outlet valve can depend on the current fill level in the water tank.
  • the preferred embodiment takes this fact into account in various ways, for example by - possibly repeated - measurements or by an analytical projection depending on the geometry of the water tank.
  • the preferred embodiments of subclaims 7 and 8 relate to particularly suitable mechanical arrangements of the water fitting system.
  • Fig. 1 is a proposed water fitting system with a water tank 1, in this case a foot bath 1a, an electrical control unit 2, an operating unit 3, a fresh water valve 4, which is an electrical valve 4a, also referred to as an "e-valve" and three water inlet openings 5 ac of the water container 1 can be seen.
  • a water tank 1 in this case a foot bath 1a
  • an electrical control unit 2 an operating unit 3
  • a fresh water valve 4 which is an electrical valve 4a, also referred to as an "e-valve”
  • three water inlet openings 5 ac of the water container 1 can be seen.
  • the present control unit 3 consists of a simple button. However, it can also be any other type of human-machine interface. These include, in particular, touch devices with several buttons or touch pads and other electronic input devices.
  • the water fitting system also has a water outlet valve 6 of the water tank 1, which in the present case is an eccentric 6a.
  • This eccentric 6a here comprises a stopper 6b and an actuator 6c for moving the stopper 6b.
  • the control unit 3 is coupled in terms of signal technology to the electrical control unit 2 and that the electrical control unit 2 is coupled in terms of control technology to the fresh water valve 4 on the one hand and to the water outlet valve 6 on the other hand.
  • signals can be exchanged between the control unit 3 and the electrical control unit 2 and the electrical control unit 2 can control both the fresh water valve 4 and the water outlet valve 6 and can also receive data from them.
  • the fresh water valve 4 is connected to at least one of the water inlet openings 5a-c via at least one feed pipe 7a-b. Is preferred, as in the Fig. 1 shown that the fresh water valve 4 is connected to each of the water inlet openings 5a-c via at least one feed pipe 7a-b.
  • the proposed water fitting system is now characterized in that the electrical control unit 2 has a data memory 8 for calibration information.
  • This calibration information relates a flow behavior of the fresh water valve 4 to a flow behavior of the water outlet valve 6.
  • This "relate” can be done on the one hand in such a way that for each position - in the sense of a degree of opening or closing - of the fresh water valve 4 the flow rate of fresh water corresponding to this position is known, and at the same time the exact outflow through the water outlet valve 6 in the open position of the water outlet valve 6 is also known.
  • An exemplary order of magnitude for such a flow rate of an open fresh water valve is approximately 40 liters per minute.
  • the "mentioned in relation" of the flow behavior of the fresh water valve 4 to the outflow behavior of the water outlet valve 6 can also be realized in that only a ratio between the amount of water flowing in with an open fresh water valve 4 to the amount of water flowing out with an open water outlet valve 6 is known.
  • this calibration information can be any information that puts these two quantities in a certain ratio, which can also be done, as described, by naming the two quantities exactly. Variations in time or differentiations depending on the binary or continuous or in any intermediate setting of the water outlet valve 6 or the fresh water valve 4 can also be taken into account.
  • the proposed water fitting system is further characterized in that the electrical control unit 2 is set up to control the fresh water valve 4 and the water outlet valve 6 based on the calibration information in such a way that a fill level 9 of the water container 1 is set to a predetermined course.
  • a basic possibility for such a predetermined course consists in a constant course of the fill level, that is, a constant fill level 9 of the water tank 1. Accordingly, it is preferred that the electrical control unit 2 is set up to control the fresh water valve 4 and the water outlet valve 6 based on the calibration information to be controlled such that a current flow rate of the fresh water valve 4 essentially corresponds to a current flow rate of the water outlet valve 6 in order to keep a fill level 9 of the water container 1 essentially constant.
  • the flow rate of the fresh water valve 4 it is not necessary for the flow rate of the fresh water valve 4 to essentially correspond to the flow rate of the water outlet valve 6 at any arbitrarily selected time interval, but this can be seen for a period of observation of, for example, several seconds, in particular 2 seconds that the result is achieved that the fill level 9 of the water container 1 is kept essentially constant and, for example in a foot bath 1a, does not fluctuate by more than a few millimeters or preferably by at most one millimeter.
  • the fill level could change with a predetermined period, which could be 30 seconds, for example, with a certain amplitude and approximately sinusoidally, such that the maximum level does not exceed said fill level 9.
  • a predetermined period which could be 30 seconds, for example, with a certain amplitude and approximately sinusoidally, such that the maximum level does not exceed said fill level 9.
  • a kind of tidal choreography can be created be realized in the water tank.
  • Other variants are also conceivable.
  • the fresh water valve 4 and / or the water outlet valve 6 can be controlled manually by the user, the electrical control unit 2 being set up to control the fresh water valve 4 or water outlet valve 6, which is not manually controlled in each case, based on the calibration information, as explained above, such that a Fill level 9 of the water tank 1 is set to a predetermined course, preferably that a current flow rate of the fresh water valve 4 essentially corresponds to a current flow rate of the water outlet valve 6 in order to keep a fill level 9 of the water tank 1 essentially constant. As a result, the user no longer has to worry about maintaining the fill level 9 when manually controlling the fresh water valve 4 or the water outlet valve 6.
  • the electrical control unit 2 is set up to execute a calibration routine in which the calibration information is generated, based on a measurement of a water inlet quantity flowing through the fresh water valve 4 in a filling routine and based on a measurement an expiry time from the water tank 1 after opening the water outlet valve 6 in an emptying routine.
  • a filling routine is first carried out and the water inlet quantity that has flowed through the fresh water valve 4 is measured, and in a subsequent emptying routine the run-out time from the water container 1 after opening the water outlet valve 6 is also measured.
  • the measurement of the water inlet quantity is a function of the fresh water valve 4, whereas here the run-down time is measured by the electrical control unit 2.
  • the average current drainage amount of the water outlet valve 6 can thus be determined from the ratio of the amount of water inlet and the run-out time.
  • This calibration routine is used in conjunction with the Fig. 3 are discussed in more detail below. At this point, however, reference is made to a preferred embodiment of the water fitting system, in which the measurement of the water inlet quantity is based on the reception of a fill level signal generated by the control unit 3.
  • This fill level signal can be a simple binary signal, which is generated by the user in the fill routine, for example, by touching the operating unit 3 when the desired fill level is reached or otherwise actuated. In this way, a desired level of the fill level that can be set by the user can be selected automatically.
  • the fill level signal includes information about a level of the fill level in the water tank 1.
  • the operator can, for example, use the control unit 3 to enter a water level read on the edge of the water tank 1, which control unit 3 then transmits this information to the electrical control unit 2.
  • the measurement of the run-down time is preferably based on the receipt of a vacancy signal generated by the operating unit 3.
  • the emptying routine can be ended exactly when the operator actuates the operating unit 3 by simply pressing after all the water has flowed out of the water tank 1. Accordingly, this vacancy signal can be the signal for the electrical control unit 2 to provide the expiry time as ended.
  • the water outlet valve 6 can then be opened a little longer than the measured run-off time for the purpose of completely emptying the water container, in order to ensure complete emptying.
  • a 10% longer opening time compared to the measured run-down time would be suitable.
  • the leakage behavior can be determined even more precisely, for example in a preferred embodiment of the water fitting system, in which the calibration information comprises discharge coefficients, each discharge coefficient characterizing a discharge rate from the water outlet valve 6 and being assigned to a level in the water tank 1. It has already been pointed out that when the water outlet valve 6 is open, the level in the water tank 1 does not generally decrease linearly, but rather the water runs out faster at a higher level than at a low level.
  • the assignment of the said discharge coefficients to different levels is one possibility is to take this into account.
  • the outflow coefficient can directly indicate the outflow rate determined for the respective level, represent a correction value in the sense of the determined deviation from the linear outflow rate, or represent other information with which the non-linear course can be simulated as a result.
  • Such outflow coefficients can preferably be determined based on the levels in the water tank 1 measured in the emptying routine after the water outlet valve 6 has been opened. It is therefore possible to measure the current level in the water tank 1 at various times after opening the water outlet valve 6 in the emptying routine, and in this way this non-linear behavior can be reconstructed. This measurement can be carried out on the one hand by sensors or on the other hand by user input, for example by means of the operating unit 3 during the emptying routine.
  • the outflow rate essentially depends on the geometry of the water tank 1 as a function of the level in the water tank 1, it can also be determined by knowing the geometry of the water tank 1. It is therefore also preferred that the runoff coefficients are determined based on a geometry of the water tank 1. If the electrical control unit 2 receives information about the geometry of the water container 1, which can be done either by coding in the data memory 8, by reading from an external memory or by input using the control unit 3, it can do so based on this information select a set of runoff coefficients associated with this geometry, preferably several such sets of runoff coefficients being stored in the data memory 8. These runoff coefficients can in turn have been determined analytically, that is to say by calculations. As an alternative or in addition, corresponding laboratory measurements can be carried out on these geometries, which are preferably also included in the determination of the runoff coefficients.
  • a device which is particularly pleasant for the foot 10 of the user is obtained if, as preferred, the water inlet openings 5a-c have one or more floor inlet nozzles 12a-b arranged on a bottom surface 11 of the water container 1.
  • the bottom inlet nozzles 12a-b can either focus the water more in the inlet direction than for the bottom inlet nozzle 12a in the Fig. 1 shown, or at a further angle, as for the bottom inlet nozzle 12b in the Fig. 1 shown, let into the water tank 1.
  • substantially vertical arrangement of these floor inlet nozzles 12a-b the foot 10 of the user can be washed directly by the water on its underside.
  • the water inlet openings 5a-c have one or more wall inlet nozzles 14 arranged on a wall surface 13 of the water container 1. These wall inlet nozzles 14 are preferably arranged essentially horizontally. The possibility of water inlet from different directions makes it possible to implement variable choreographies by which the foot 10 of the user is washed up from different directions.
  • a footrest surface 15 with flow openings 16 is arranged above the bottom surface 11 of the water container 1, the flow openings 16 being arranged in this way are that at least one floor inlet nozzle 12 is aligned with one flow opening 16 each. In this way, the user can place or support his foot 10 as desired and the foot 10 is still at a suitable distance from the floor inlet nozzles 12 a-b.
  • the fresh water valve 4 is set up to supply fresh water to each of the water inlet openings 5 a, b, c independently of one another, controlled by the electrical control unit 2. In this way, fresh water of different temperatures can emerge at each water inlet opening 5 ac, so that in the exemplary embodiment of FIG Fig. 1 the foot 10 of the user is washed with warmer water from below, while colder water hits him from above or vice versa.

In this way, the amount of water currently flowing out can be finer adjusted by the water outlet valve 6.
