Description

[0001] This application is a divisional application with application number 202010683741.X, application date July 15, 2020, and subject matter “Sanitary accessories for discharging prepared liquids”. Technical Field

[0002] The invention relates to a sanitary fitting for discharging prepared liquids, in particular for beverages, comprising a first control element for setting the amount of prepared liquid to be discharged and an actuating element for providing the amount of prepared liquid set by means of the first control element.

[0003] The invention also relates to a sanitary system for providing and discharging prepared liquids, in particular beverages.

[0004] The invention further relates to a method for providing and discharging a prepared liquid, in particular a beverage. Background Art

[0005] Many different types of sanitary fittings are known. Known sanitary fittings include, for example, a fitting body with at least one control element for setting at least one property of a fluid flow guided through the sanitary fitting. The property may be, for example, the flow rate of the fluid flow or the temperature of the fluid flow. In known sanitary fittings, the fluid flow is mixed from separate cold and warm water flows, for example by means of a mixing tap, and is guided from there to an outlet.

[0006] In order to increase the functionality, for example, DE 10 2013 000 773 A1 or DE 10 2013 002 236 A1 discloses a sanitary fitting having at least one first actuating element for setting the temperature and / or amount of mixed water and at least one second actuating element for setting the amount of hot water. The second actuating element, which enables the amount of hot water to be set, is designed here as a rotary selector switch. It must first be turned in a first direction to activate the hot water function. It must then be turned in a direction opposite to the first direction to set the desired amount of hot water.

[0007] The disadvantage here is that the operation of the second actuating element is awkward and complicated. At the same time, the flexibility in providing different prepared fluid flows is greatly limited. Summary of the invention

[0008] It is therefore an object of the present invention to provide a sanitary fitting for discharging prepared liquids, in particular beverages, and a corresponding sanitary system which allow simple handling, a high degree of flexibility and inexpensive implementation.

[0009] Another object of the present invention is to provide a method for providing and dispensing a prepared liquid, in particular a beverage, which method is simple to operate, inexpensive and has a high degree of flexibility.

[0010] A further object of the invention is to provide an alternative sanitary fitting, an alternative sanitary system and an alternative method for providing and discharging prepared liquids, in particular beverages.

[0011] The present invention achieves these objects by using, in one embodiment, a sanitary fitting for discharging prepared liquids, in particular beverages, which comprises a first control element for setting the amount of prepared liquid to be discharged and an actuating element for providing the amount of prepared liquid set by means of the first element, wherein at least one second control element is arranged, which is used to select the preparation type of the unprepared liquid, in particular to select from at least two different preparation types, and the first and at least one second control element can be operated independently of each other.

[0012] The invention achieves the object in another embodiment by a sanitary system for providing prepared liquids, in particular beverages, comprising a sanitary fitting according to the claim, a preparation unit connected to the sanitary fitting for providing the prepared liquid, and a control unit connected to the sanitary fitting on the one hand and to the preparation unit on the other hand for controlling the sanitary fitting and the preparation unit.

[0013] In another embodiment, the present invention achieves the above object by a method for providing and discharging prepared drinking liquids, in particular water, using a sanitary fitting according to the claim, the method comprising the following steps:

[0014] The amount of prepared liquid to be discharged is set by means of a first control element,

[0015] providing or setting at least one preparation type of the unprepared liquid, in particular selected from at least two different preparation types, by means of at least one second control element,

[0016] - actuating the actuating element,

[0017] - discharging the prepared liquid and the neutral liquid, in particular the unprepared liquid, so that before a set amount is reached, only the neutral liquid for discharging is provided and discharged, and the discharging is stopped when the set amount is reached,

[0018] After complete discharge, a set amount of prepared liquid has been discharged in a set amount and preparation type.

[0019] In another embodiment, the invention achieves the object by a control unit for a sanitary fitting, the control unit being designed to transmit at least one signal to the sanitary fitting for discharging a metered amount of a liquid of a selected preparation type, thereby

[0020] - before complete discharge of the metered amount is reached, only neutral liquid, in particular unprepared liquid, is discharged through the sanitary fitting, and

[0021] - after complete discharge of the fixed quantity through the sanitary fitting, the discharge is stopped,

[0022] Thus, after complete discharge of the metered amount, the prepared liquid of the set amount and preparation type has been discharged via the sanitary fitting.

[0023] The term "prepared liquid" is to be understood in the broadest sense and, in particular in the claims and preferably in the description, refers to a liquid whose properties and / or composition are additionally modified by a separate device, in particular water in the form of tap water from a water supplier / water provider or the like whose properties and / or composition are additionally modified by a separate device. For example, the prepared water may have a high temperature (so-called hot water), a different degree of carbonation / carbonation than the water originally provided by the water supplier / water provider, a partially different composition, etc. The term "prepared liquid" is not to be understood in particular as warm or cold water which is usually provided by a water supplier / water provider to single-family homes, multi-family homes, etc. and whose temperature can be adjusted by a heater or the like.

[0024] The term "neutral liquid" is to be understood in the broadest sense and, in particular in the claims, preferably in the description, refers to a liquid which has no effect on the prepared liquid, at least organoleptically, in particular in terms of taste or smell. For example, the neutral liquid may be unfiltered water or filtered water.

[0025] The term "preparation type" is to be understood in the broadest sense and, in particular in the claims and preferably in the description, refers not only to the basic preparation type of the liquid, such as whether the water is carbonated / carbonated, but also to the degree, intensity or concentration of the preparation, such as the intensity of the carbonation. Different preparation types then mean, for example, different degrees of carbonation, such as "still", "medium" or "classic". Different preparation types also mean different temperatures of hot water, different degrees of filtered water, different concentrations of flavoring additives or flavorings, different types and different concentrations of mineralization and different concentrations of the same type of mineralization or similar preparations. The term "preparation type" in particular also includes "unprepared".

[0026] One advantage of this is that operability and flexibility are significantly improved. Another advantage is that a simple and inexpensive implementation or simple and inexpensive execution (Durchführung) is possible.

[0027] Other features, advantages and other embodiments of the invention will be apparent from or in the following description.

[0028] According to an advantageous development, a first display unit is provided which is designed to display at least two different preparation types. This improves the operability of the sanitary fitting and at the same time provides a high degree of flexibility when selecting various preparation types.

[0029] According to a further advantageous development, a second display unit is arranged, which is designed to display at least one operating state and / or at least one preparation type of the sanitary fitting. This also improves the operability of the sanitary fitting, in other words, reduces incorrect operation.

[0030] According to a further advantageous refinement, at least one display unit is designed for optical and / or acoustic display. In addition to enhancing operability, this also increases flexibility, since various operating states and / or preparation types can be indicated by various optical and / or acoustic signals.

[0031] According to a further advantageous development, at least one display unit and / or at least one control element is designed in an annular shape.In addition to a high level of visual experience and improved perceptibility for the user of the sanitary fitting, the operability is also improved.

[0032] According to a further advantageous development, at least three optically different displays can be provided by at least one display unit designed for optical display. In this way, a variety of possible operating states or preparation types can be displayed in a simple manner.

[0033] According to a further advantageous development, two display units are arranged, which are arranged on different axial sides of the first control element. This also improves the perceptibility, since the user of the sanitary fitting can directly and simultaneously perceive the display via the two display units when actuating the first control element. Due to the arrangement of the display units on different sides of the first control element, confusion is virtually ruled out even in the case of identical light signals, for example, for the preparation type on the one hand and for the operating state on the other hand.

[0034] According to a further advantageous improvement, the actuating element can be actuated by contact and / or pressing or in a contactless manner, in particular the actuating element is configured to recognize gestures. The actuating element can thus be actuated flexibly. The advantage of actuation by contact is that, for example, the user of the sanitary fitting can be given a pleasant tactile sensation during actuation. The advantage of actuation by pressing is the direct feedback of the completed actuation to the user, while the advantage of contactless actuation of the actuating element is that contamination of the actuating element is almost excluded. If the actuating element can recognize gestures, undesired actuations are further reduced, since only defined and recognized gestures can actuate the actuating element. Actuation of the actuating element by contact should also be understood in particular as pressure actuation of a button.

[0035] According to a further advantageous refinement, the actuating element has a circular surface for actuating, in particular a point for actuating. If the actuating element is designed as a circular button, dot or similar shape, in addition to a harmonious and optically high-quality appearance, particularly easy operability is possible.

[0036] According to a further advantageous development, a single-lever mixer tap for discharging unprepared warm water and cold water is provided. This enables a mixture of warm water and cold water to be provided in a simple and convenient manner.

[0037] According to a further advantageous development, at least two separate outlets are provided, of which at least one outlet is designed exclusively for discharging unprepared warm water and cold water, and at least one further outlet is designed for discharging prepared liquids. The advantage of separate outlets is that, for example, cold water can be provided at a first outlet and prepared water can be provided at a second outlet independently of one another. The separation of the two outlets is also advantageous for hygienic reasons (for example due to residual water).

[0038] According to a further advantageous development, the at least two outlets are arranged spaced apart from one another. This minimizes confusion of the two outlets and simultaneously increases flexibility, since both outlets can be used in a simple manner.

[0039] According to a further advantageous development, at least one of the outlets is arranged movably and has a releasable locking unit, which is designed to releasably fix the outlet to an element of the sanitary fitting, in particular by means of magnetic forces. One of the advantages achieved thereby is that the sanitary fitting can be easily and at the same time flexibly handled. For example, with the releasable nature and / or fixing capability of the outlet, it is possible to pivot the outlet or to change the height of the outlet.

[0040] According to a further advantageous refinement, the first and at least one second control element can each be actuated by a rotational movement, and the second control element can also be actuated by an axial movement. This enables both control elements to be easily operated while being highly flexible with regard to different types of actuation of the control elements.

[0041] According to a further advantageous development, the at least one second control element has at least two, in particular four, defined stop positions in the rotational movement. This enables tactile feedback to be provided to the user of the sanitary fitting, thereby reducing inaccurate, error-prone operation of the sanitary fitting; the probability of accidental actuation is reduced.

[0042] According to a further advantageous development, a plurality of second control elements are provided, which can be actuated independently of one another. This increases the flexibility of the sanitary fitting when selecting and providing water of different preparation types.

[0043] According to a further advantageous development of the sanitary system, the preparation unit comprises at least one of the following units: a filter unit, a heating unit, a storage unit, a concentration unit, a carbonation / carbonation unit, a cooling unit. Thus, a plurality of possible preparation types for the liquid can be provided. It is also possible to store various prepared liquids in order to produce a faster discharge when the corresponding prepared liquid is selected again.

[0044] According to a further advantageous improvement of the sanitary system, a flow meter is provided for measuring the flow of liquid, in particular water, through the preparation unit. This has the advantage that, for example, the amount of prepared water can be accurately provided.

[0045] According to a further advantageous development of the sanitary system, the control unit is connected to the flow meter and is designed to calculate the service life of the components of the preparation unit based on the measured flow rate and to display the service life via at least one display unit of the sanitary fitting. This increases the reliability of the sanitary system, since, for example, the filter of the filter unit can be replaced in good time, so that liquids, in particular water, can be reliably filtered at any time.

[0046] According to a further advantageous development of the sanitary system, the filter unit is connected to the sanitary fitting via a first valve controllable by the control unit, and the storage unit is connected to the sanitary fitting via a second valve controllable by the control unit. By means of the controllable valves, for example, prepared water can be provided in a simple manner via the filter unit or from the storage unit.

[0047] According to a further advantageous development, at least one of the valves is designed as a solenoid valve. This enables a simple, rapid and reliable actuation of the respective valve.

[0048] According to a further advantageous development of the method, after the actuation of the actuating element, the prepared liquid is discharged within a settable period of time. This increases the operating convenience for the user of the sanitary fitting, since the user only has to trigger the actuation, for example with a finger, and can then fill up with prepared water with both hands. Another advantage is that a set amount of prepared liquid can be obtained, wherein the set amount is then determined by means of a flow measurement.

[0049] According to a further advantageous development of the method, when the actuating element is actuated again during the discharge of the prepared liquid, the discharge is at least interrupted, in particular stopped. Thus, on the one hand, liquid consumption can be reduced if, for example, only small amounts are required; on the other hand, for certain specific functions, for example, a rapid stop of the discharge of the prepared liquid can be provided.

[0050] According to a further advantageous refinement, at least one of the following preparation types is provided: hot water, filtered water, carbonated water, cooled water, water mixed with concentrate. This means that a plurality of possible preparation types for water can be provided.

[0051] According to a further advantageous development of the method, the preparation type is selected by rotating and axially moving at least one second slave element from an axial rest position, in particular against a restoring force. This has the advantage that it enables the preparation type to be selected in a reliable manner to discharge the correspondingly prepared liquid.

[0052] According to a further advantageous development, after selecting at least one preparation type, at least one second control element returns to its axial rest position, in particular by means of a spring force. This provides the user with a uniform starting position of the second control element for a large number of selection options; overall, operation is simplified.

[0053] According to a further advantageous development, the type of hot water preparation is indicated by at least one display unit of the sanitary fitting. This has the advantage that the risk of incorrect operation by the user in the case of hot water or the risk of accidentally draining hot water is reduced.

[0054] Further important features and advantages of the invention emerge from the dependent claims, the drawings and the associated description of the drawings.

[0055] It is obvious that the features mentioned above and those yet to be explained hereinafter can be used not only in the respectively specified combination, but they can also be used in other combinations or alone, without departing from the scope of the present invention.

[0065] Figure 1 A three-dimensional view of a sanitary fitting according to an embodiment of the invention is shown.

[0066] exist Figure 1 A sanitary fitting 1 for a kitchen is shown in detail in FIG. Figure 4 and 5 The sanitary fitting 1 comprises a cylindrical fitting body 2, on which control element units 3a, 3b are arranged perpendicularly to the cylinder axis (i.e. along axis A) on different sides of the fitting body 2. Here, the first control element unit 3a is used to set the mixed water temperature and the mixed water flow rate, which is based on unprepared warm water and cold water. For this purpose, the first control element unit 3a comprises a single-lever mixer tap 8. With the help of the second control element unit 3b (which is located below Figure 2 , 3 and 7 ), the amount and type of preparation for unprepared water can be set and the discharge of an amount of prepared water can be triggered.

[0067] A water outlet 5 is also arranged pivotably on the fitting body 2 via the outlet arm 4, to which the mixed water can be applied. Furthermore, the water outlet 5 is connected to a holding arm 6 via a releasable connection 56, which in turn is pivotably arranged on the fitting body 2 parallel to the cylinder axis of the fitting body 2. The releasable connection 56 can be realized, for example, by magnetic force. On the underside of the holding arm 6, a further water outlet 7 is arranged, through which the prepared water (which can be set via the second control element unit 3b) can be discharged.

[0068] Figure 2 Shown according to Figure 1 Three-dimensional details of sanitary accessories, Figure 3 Shown according to Figure 2 Axial top view of the control element unit of a sanitary fitting.

[0069] exist Figure 2 3. The second control element unit 3b is shown in detail in FIG. The second control element unit 3b comprises a first control element 300 in the form of a ring rotatable about an axis A arranged perpendicularly to the axis of the cylindrical fitting body 2. The first control element 300 is used to set the desired amount of prepared water and is marked with a numerical scale in milliliters for the desired amount, here "100", "200", "300", "500", "750" and "0". The scale here is non-linear, but in another embodiment it can also be linear. Other or modified scales can also be used.

[0070] Marker 303 is set along Figure 2 The marking 303 is arranged on the right side of the axis A in the display and near the first control element 300, which allows the set amount to be dispensed by the first control element 300 on the one hand. On the other hand, the marking 303 is also designed as a second display unit in addition to the first display unit 301. The first display unit 301 is arranged on the left side of the first control element 300 and is configured in a ring shape. With the help of the first display unit 301, different color representations can be displayed, for example, at least red, white, green, yellow and / or orange or similar colors. Different luminous colors, in particular red and blue, can also be displayed with the help of the second display unit 303. Each of the two display units 301, 303 can also display a color intermittently, in other words, provide a flash of the corresponding color. Alternatively or additionally, the display units 301, 303 can also provide an acoustic signal, such as an intermittent beep or a similar sound.

[0071] In addition, the second control element unit 3b has a second control element 302, which is also annular and arranged on the left side near the first display unit 301. The second control element 302 has undulations on its periphery so that the user can better grasp it. The second control element 302 is formed to be rotatable and has a rotation direction R3, R4 around the axis A, and is also arranged to be movable in the axial directions R1, R2 along the axis A on the other hand. A circular surface 304 with a trigger point 304' is arranged on the surface of the second control element 302 perpendicular to the axis A, which is used to trigger the actuating element 305. The discharge of the prepared water is triggered by means of the actuating element 305. By rotating in the direction R4, the second actuating element 302 can enter four different stop positions P1, P2, P3, P4. Rotation in the opposite direction R3 can be allowed, but it may not be allowed, and rotation in the opposite direction R3 is not allowed so that the user can only continue to rotate the second control element 302 in the direction R4.

[0072] In accordance with Figure 3 In the top view of FIG. 3 , different positions P1, P2, P3 and P4 are shown, which are offset from each other on the circumference at an angle of 90°. As already explained, an actuating element 305 having a circular surface 304 with a trigger point 304' is arranged on the end face. The actuating element 305 can be designed to be actuable without contact or to be actuable by touching the trigger point 304'. The actuating element 305 can be designed in the form of an infrared sensor, so that the actuating element 305 is triggered when the trigger point 304' of the surface 304 is touched.

[0073] The operation of the sanitary fitting 1 will now be described in detail. For this purpose, the sanitary fitting 1 is initially in a rest state / standby mode. An arbitrary amount can be set by means of the first control element 300, but the prepared water is not discharged. The second display unit 303 then illuminates, for example blue, the first display unit 301 is not illuminated and the trigger point 304' is active, i.e., at a corresponding touch, the actuating element 305 is triggered.

[0074] When the amount is set to "0" by means of the first control element, the sanitary fitting 1 is in the so-called cleaning mode. The display units 301, 303 are not illuminated and the trigger point 304' is switched off or inactive. In this way, incorrect operation during the cleaning process is prevented. The cleaning mode can be designed, on the one hand, so that water (whether prepared water and / or unprepared water) cannot be accidentally discharged, for example in order to be able to clean the sanitary fitting 1 from the outside by wiping or similar operations. On the other hand, alternatively or additionally, the cleaning mode can also trigger the specific passage of a certain cleaning liquid (for example for descaling or similar purposes).

[0075] In order to discharge the prepared water (here in the form of filtered water), the first control element 300 is set to a number, i.e. a defined amount of filtered water to be discharged. Then, the second display unit 303 emits a blue light, the first display unit 301 does not emit light. Now, the amount can be readjusted or set accordingly. By, for example, placing a finger on the trigger point 304', the actuating element 305 is triggered and the delivery of the desired amount of filtered water is started. The second display unit 303 flashes blue, the first display unit 301 does not emit light. The delivery of the prepared water can be stopped in advance by operating the trigger point 304' of the actuating element 305 again.

[0076] Starting from the rest state / standby mode, the following steps are performed to discharge or draw off the prepared water in the form of hot water. First, the first control element 300 is set to any number, which can correspond to the amount of hot water to be delivered. In this case, the second display unit 303 initially emits a blue light, while the first display unit 301 does not emit light. Then, the second control element 302 is pressed in the axial direction R1, that is, in the direction towards the first display unit 301. Then, the second control element 302 is rotated from the first stop position P1, P2, P3, P4 to the next stop position P2, P3, P4, P1 in the pressed state in the direction R4 or direction R3. Then the second control element 302 is released, so that the second control element 302 moves again in the direction R2 to its axial starting position. Now, the second display unit 303 lights up red, and the first display unit 301 also lights up red. The hot water function of the sanitary fitting 1 is now activated, wherein the amount of hot water to be set can still be changed. By actuating the actuating element 305, for example by placing a finger on the trigger point 304', a desired amount of boiling hot water can be drawn out. Here, in order to discharge the desired amount of hot water, it is sufficient to briefly place the finger on the trigger point 304' of the actuating element 305. In other words, after the actuating element 305 is triggered, it is no longer necessary to touch it. Then, during the discharge, the second display unit 303 flashes red and the first display unit 301 flashes red to indicate the discharge of hot water.

[0077] The hot water function is activated for a certain period of time, for example 8 or 10 seconds, after the second control element 302 is in its axial rest position again. During this first period of time, hot water can be discharged by triggering the actuating element 305. If the actuating element 305 is not actuated during this period, the sanitary fitting 1 returns to the rest mode / standby mode.

[0078] If the actuating element 305 has been activated within the first time period, in other words, hot water has been drawn off, the second display unit 303 lights up red within the second time period, while the first display unit 301 no longer lights up. This indicates to the user of the sanitary fitting 1 that there is still hot water available for discharge in the corresponding pipeline. After the second time period, the hot water has cooled down and the sanitary fitting 1 switches to the rest mode / standby mode, i.e. the second display unit 303 lights up blue again. For example, the duration of the second time period can be 5, 10 or 15 minutes.

[0079] In the second time period, no other type of preparation or water prepared in a manner other than hot water can be provided. If the actuating element 305 is triggered in the second time period, this is indicated optically by the second display unit 303, for example by flashing red a number of times, in particular five times. In addition, the first display unit 301 also flashes red a number of times, in particular corresponding to the second display unit 303. However, the discharge of hot water does not occur. Only when the actuating element 305 is actuated again after the corresponding display by the first display unit 301 and the second display unit 303, can water prepared in a preparation type other than hot water be drawn out, and the water prepared in a preparation type other than hot water be discharged, in particular after the hot water still in the supply reaching the corresponding outlet.

[0080] During the discharge of hot water, the discharge can be interrupted at any time by moving (more precisely by pressing) the second control element 302 in the axial direction R1. The discharge can also be interrupted by actuating the actuating element 305 and can be continued by actuating it again.

[0081] If the interruption of the hot water discharge does not occur, the hot water discharge can also be performed as follows: for example, 500 ml of hot water is to be discharged, and if the line capacity of the hot water supply unit (such as a boiler or the like) is 30 ml, 30 ml of cold water is discharged first, and then the hot water from the boiler, whose temperature is higher than the required temperature, but after the 470 ml of hot water higher than the required temperature is discharged, when mixed with the 30 ml of cold water, 500 ml of hot water of the required temperature will be produced. The hot water is discharged in such a way that after the 500 ml is discharged, cold water is again provided at the water outlet 7.

[0082] Starting from the static mode / standby mode, when the filtered water is being drained, the second display unit 303 can provide a display depending on the use of the filter, for example by flashing green, which indicates that the filter is not functioning properly. If the actuating element 305 is actuated and prepared water, in particular filtered water, is provided, the second display unit 303 flashes green, for example, thereby indicating to the user of the sanitary fitting 1 that the filter cartridge must be replaced. When draining hot water, the filter can be indicated by the second display unit 303 flashing green and red alternately. Another color of the second display unit 303 can also indicate that the capacity of the filter has been exhausted, in other words, it must be replaced. If filtered water is drawn off or drained, the second display unit 303 lights up blue, for example, and the first display unit 301 flashes green. For example, if hot water is drawn off or drained, the second display unit 303 lights up red, while the first display unit flashes green.

[0083] Figure 4 A sanitation system according to an embodiment of the present invention is shown. Figure 5 The schematic diagram shows the Figure 4 Control unit for the sanitary system.

[0084] Figure 4 The sanitation system 200 is shown in detail, and the sanitation system includes Figure 1-3 The sanitary fitting 1 of the present invention and the preparation unit 201 and the control unit 100 are provided. Specifically, a filter unit 106 is arranged, which is connected to the cold water line 21b for supplying cold water. By means of the filter unit 106, filtered water can be provided via the line 20c, the control unit 100 and via the line 20 connected to the water outlet 7. The filtered water passes through the flow meter 105 of the control unit 100, and the amount flowing through is measured. The control unit 100 is designed to determine when the filter cartridge (Filterkartusche) of the filter unit 106 must be replaced based on the measured amount of flow. A flow control unit 110 is arranged downstream of the flow meter 105, which has a plurality of valves 111, 113. The high-pressure boiler 103 for hot water connected to the heating unit 107 is connected to it via the supply line 20b and the safety unit 104. Then, hot water can be supplied to the pipe 20 via the second pipe 20a via the flow control unit 110 and discharged through the water outlet 7.

[0085] The control unit 100 has an electronic controller 101 and is connected to two control elements 300, 302, two display units 301, 303 and an actuating element 305 via a signal line 130 for corresponding control or actuation. The control unit 100 is also connected to a power supply 102 for its operation. Through the pipeline 20, filtered water or hot water can be discharged through the water outlet 7. The warm water pipeline 21a and the cold water pipeline 21b are connected to the first water outlet 5 via the first control element unit 3a with a mixing cartridge (Mischerkartusche), and through this arrangement, they can discharge mixed water with corresponding temperatures accordingly.

[0086] Now Figure 5 The control unit 100 is shown in detail. In addition to the electronic control 101, the control unit 100 also has a display screen 120 in the form of a touch screen or the like, through which the control unit 100 can be programmed, for example, a corresponding time period for providing a hot water function after the second actuating element 300 is actuated, a filter capacity is set according to the hardness of the water or similar settings. The safety device 104 is used to avoid excessive pressure when heating in the hot water boiler 103.

[0087] The control unit 100 is also designed so that when the user selects a quantity of prepared water (generally applicable to any fluid or liquid), it is provided so that

[0088] -The amount of water discharged corresponds to the selected amount of water, and

[0089] A certain proportion of unprepared water is present in the discharged water volume in such a way that the degree of preparation of the prepared water corresponds to a selected degree and that, after the set amount has been discharged, unprepared water is provided at the water outlet (here indicated by reference numeral 7 ).

[0090] In other words, the control unit 100 is designed, for example, as follows: for the selected preparation type "carbonated water / carbonated water (karbonisiertes Wasser)" with a carbonation degree of only "2", water is prepared with a carbonation degree of 2.2 (i.e. greater than the set carbonation degree). If the amount of water to be discharged is now 0.5 liters, 416.6666 ml of carbonated water with a degree of "2.2" is prepared and then first discharged. Afterwards, 500 ml-416.666 ml=83.333 ml of unprepared water as neutral liquid are discharged, i.e. with a carbonation degree of "1", so that on average 500 ml with a carbonation degree of "2" are discharged. This makes it unnecessary to additionally flush the line with a neutral liquid, for example, when adding fruit juice concentrate to unprepared water or the like. This avoids dripping (Nachlauf) at the outlet.

[0091] Figure 6 A method for providing and discharging a prepared liquid according to an embodiment of the present invention is shown.

[0092] Figure 6 A method for providing and discharging prepared drinking water using the sanitary fittings according to any one of the claims of the present disclosure is shown.
