    The invention relates to a terminal sanitary fitting with a connection for cold water, a connection for hot water, an outlet, a fitting body, coupled to an actuator first valve, coupled to an electronic circuit unit another valve, a power supply and two channels with closure devices, wherein the channels for supplying the valves with cold and hot water and the closure devices are designed as a closure of the open holes of the channels and independent of the position of the actuator adjustment of volume flow and temperature of the delivered over the other valve mixed water.
    List of abbreviations and terminology: ESA Terminal Sanitary fitting - Armature for
    Extraction of water for sanitary purposes, in particular for showers, baths, washbasins, sinks, bidets, urinals and WCs ESH Electronic circuit unit SFS Stagnation rinsing - rinsing out of
    Stagnation water from ESA VSSE scalding protection with locking device ESAs are fittings for the usual removal of water for human use. During downtimes, for example, outside the opening and / or seasons, during holidays or in the absence of occupancy of hotel rooms, there is a risk that dissolve in the stagnant water substances from the materials in contact with this and beyond in the ESA from the Water supply to flushed or retrogradely introduced microorganisms, such as bacteria, fungi or amoebae, increase the stagnation water as a result of this contamination no longer meets the requirements of the Drinking Water Ordinance and the use of the water is a danger to human health. ESAs with a proximity sensor, an ESH and a valve are known inter alia from AT404150, AT412824, AT514160, DE19651132, DE10148675, EP2169123, EP0813636 and US5961095. From US2004254746 an ESA is also known, which rinses the stagnation water automatically when exceeding a maximum residence time from the ESA. Valves for operating ESAs are known inter alia from EP0825370.
    From DE102007009007 is a device for monitoring the flushing activities of a water pipe with sensors for detecting the volume flow and / or the temperature of the water flowing through or a
    Tilt sensor for detecting the position of an operating element of an ESA known.
    When used with care, especially by children and demented people, ESAs assume the risk of scalding by releasing water at temperatures in excess of 42 ° C. NL1005957 discloses a device which warns the user by a color change to red when the temperature exceeds a predetermined limit of 38 ° C. The disadvantage of this solution is that it does not eliminate the risk of scalding, especially in children and demented people. Also state of the art are ESAs with a thermostatic mixer, as exemplified in GB2523624.
    Disadvantages of these systems are not only the considerably higher production costs of thermostatic mixing valves compared to conventional mixing valves, but also their increased risk of microbial contamination in areas with unfavorable flow conditions.
    Particularly when used in the kitchen, the use of ESAs is becoming increasingly popular, which involves both conventional water extraction over one
    Activation device as well as an automatic release option via a proximity sensor, in order to avoid having to touch the possibly soiled hands, the ESA. Such ESAs are known from DE19625252, EP3098356, WO2012123121 and WO2013134525. Disadvantages of these solutions are the numerous hose connections and / or pipelines which increase the volume of stagnation water and thus also increase the risk of contamination.
    In DE102015002779 an ESA is disclosed which distinguishes between manual and sensor controlled sampling by evaluating the object detected with a proximity sensor. A disadvantage of this solution is the additional cost of the otherwise not necessary proximity sensor for valves for purely manual and not sensor-controlled removal.
    From DE102014104395 an ESA is known, which rinses the stagnation water as a function of the temperature in the course of an SFS automatically from the ESA. A disadvantage of this solution is the high cost of the elaborately designed valve with the two vertically adjustable adjusting bolt with the required electric motors, the temperature sensor and the electronic temperature controller.
    The object underlying the invention is therefore to provide a low-cost ESA with a connection for cold water, a connection for hot water, an outlet, a fitting body, coupled to an actuator first valve, a power supply and coupled to an ESH further valve specify, in which the adjustment of volume flow and temperature of the mixed water discharged via the further valve is formed independently of the position of the actuating device.
    The object of the invention is achieved in an ESA of the type mentioned in that the ESA has two channels with closure devices, the channels for supplying the valves with hot and cold water and the closure devices as closure of the open holes of the channels and of the Position of the actuator independent adjustment of volume flow and temperature of the delivered over the other valve mixed water are formed.
    Advantageously, it can be provided that the ESH comprises a microcontroller, a memory and / or a power supply.
    In particular, it can be provided that the valves are designed as a single-lever cartridge, as a solenoid valve, as a thermostatic valve, as a mixing valve, as a control valve, as a proportional valve, as a control valve, as a throttle valve or as a combination of these components.
    Preferably, it may be provided that the first valve is arranged in an area through which the actuating device flows only when it is manually removed, and the further valve is arranged in an area through which the ESH flows only when it is automatically purged.
    Furthermore, it can be provided that the ESA comprises at least one approximately T-shaped channel formed from two channels arranged approximately at right angles to one another. In a particular embodiment, it can be provided that the valves are coupled to the outlet via the at least one approximately T-shaped channel. In addition, it can be provided that at least two of the channels are arranged approximately mirror-symmetrical to each other. Advantageously, it can be provided that at least one of the channels is designed as a continuous bore with a constant or gradual or continuously decreasing diameter drill. Furthermore, a procedure may be that at least two of the channels are arranged approximately parallel to one another and / or in a plane.
    In one embodiment, it may be provided that the ESA comprises several areas with different volumes of water contents.
    In a particular embodiment, it may be provided that the further valve comprises an input and an output, which are arranged coaxially concentric with one another and through which flows in the opposite direction.
    In addition, it can be provided that the ESA comprises a flow, temperature, pressure and / or position sensor, for example for detecting a water extraction, and / or a proximity sensor, for example for non-contact triggering of a water extraction. In particular, it can be provided that the sensor is designed as immersed in the cold, warm or mixed water or fitting the fitting body or a channel temperature sensor.
    Preferably, it may be provided that the ESA comprises a VSSE for at least one of the valves.

    Fig.7 represents an ESA and details of a fitting body.
    Fig.l shows the ESA la, designed here as a washbasin fitting, which is mounted by way of example on a sink, not shown, with a fitting body 2 and an outlet 9 with a jet regulator 8 for shaping the effluent water jet 3. The fitting body 2 is through the dashboard 11th protected, at the top of which is designed as an actuating lever rotatable and pivotable actuator 12 is arranged. On the underside of the fitting body 2 are the connections for hot water PWH and cold water PWC, in each of whose openings a non-illustrated backflow preventer is inserted. The supply of hot water PWH from the building-side water installation, not shown, via the hose 6a and the supply of cold water PWC via the hose 6b. In the ESA la is exemplified running as a single-lever cartridge and coupled to the actuator 12 valve 10a arranged with the withdrawal of water by pivoting the actuator 12 resulting from the mixing ratio of the hot water PWH and cold water PWC temperature of the mixed water PWM and tilting the Actuator 12, the volume flow of the mixed water PWM is set.
    The lingering after a use in the ESA la water is referred to as stagnation water 18. During downtimes, there is a risk that dissolve in the stagnant water 18 substances or multiply microorganisms. ESA la therefore runs the risk that stagnant water will no longer meet the requirements of the Drinking Water Ordinance as the stagnation period increases and the use of water poses a threat to human health.
    FIG. 2 shows the ESA 1b as a further development of the ESA 1a. The ESA 1b additionally has the ESH 4 with the microcontroller 15 and the memory 17, the power supply 22, the valve 10b coupled to the ESH 4 and the sensor 14 for detecting a water extraction. In the simplest case, the valve 10b is designed as a solenoid valve and only releases the flow of cold water PWC or hot water PWH. In an alternative embodiment, the valve 10b has a device for adjusting the temperature and the volume flow, not shown, coupled to the actuating device 12, for example in the form of a further single-lever cartridge. In a particularly advantageous embodiment, the device for adjusting the temperature and the volume flow of the actuator 12 is decoupled and thus independent of their position. In a particularly cost-effective design, the setting of the temperature and the volume flow does not take place via a single-lever cartridge, but by way of example via a non-illustrated throttle valve in the supply lines for cold water PWC and hot water PWH valve 10b.
    The power supply 22 is exemplified executed as a battery. In alternative embodiments, the power supply 22 is designed as a power supply or as a turbine and converts the kinetic energy of the ESA lb flowing through water into electrical energy for operating the ESH 4. In a particularly compact embodiment, the power supply 22 is designed as a component of the ESH 4.
    The removal of water takes place as described in Fig.l. By way of example, the sensor 14 is embodied as a flow, temperature and / or pressure sensor that dips into the mixed water PWM and is coupled to the ESH 4. In alternative embodiments, the sensor 14 as in the cold water PWC or in the hot water PWH immersing flow, temperature and / or pressure sensor or as the fitting body 2 or one of the channels 7a-d fitting temperature sensor for detecting the temperature of the cold water PWC, Hot water PWH or the mixed water PWM or as a position sensor for detecting the position of the actuator 12 or the position of the valve 10 a executed.
    In a particularly hygienic design, the ESH 4 determines the time tSFs of the next SFS by adding the current time stamp and the maximum allowable stagnation and detected with the sensor 14 periodically, for example once per second, the water extraction, at least the states of water flow and no water flow, advantageously but also the volume flow and the temperature of the outflowing water jet 3. If the current time stamp exceeds the time tSFs in the absence of removal, the ESH 4 triggers an SFS with the valve 10b for a predetermined duration of, for example, 60 seconds, if a predetermined maximum allowable Stagnation is exceeded by example 24 hours to rinse the stagnant water 18 through the spout 9. The maximum permissible stagnation duration and the duration of the SFS are stored as parameters in the memory 17 and / or executed adjustable by means of adjustment.
    In an alternative refinement, the ESH 4 determines the time tsFs of the next SFS by adding the current time stamp and the maximum permissible stagnation duration and periodically sums the purge times tSP detected by the sensor 14 during which water is withdrawn as the sum purge time Ztsp. If the sum flushing time ZtSP exceeds the duration of the SFS with sufficient removal, the ESH 4 determines the time tSFs of the next SFS by adding the current time stamp and the maximum permissible stagnation duration. Exceeds with insufficient
    If the current timestamps use the time tSFs, the ESH 4 triggers an SFS for the difference of the total flush time Etsp over the duration of the SFS and thus ensures compliance with the minimum flushing time defined with the duration of the SFS.
    The area 5a is flowed through only with manual removal by opening the valve 10a with the actuator 12, the area 5b only with automatic flushing by opening the valve 10b through the ESH 4, the area 5c, however, both manual removal and automatic flushing. In area 5a, there is still the danger during standstill times that substances in the stagnant water dissolve or microorganisms multiply. Nevertheless, depending on the configuration of the areas 5a-c and their water contents, the risk of endangering human health compared to the ESA 1a can be significantly reduced.
    Preferably, the microcontroller 15 also includes the memory 17.
    3 shows the ESA lc as a further development of the ESA lb. The valve 10a is exemplified as a motor-operated control valve and coupled to the ESH 4, the valve 10b is omitted. The ESH 4 is coupled to the position sensor sensor 14 for detecting the position of the actuator 12 and controls with the valve 10 a temperature and flow rate of the outflowing water jet 3 according to the position of the actuator 12th
    As described in Figure 2, the ESH 4 periodically determines the need to initiate an SFS, but opens the valve 10a to perform the SFS. Irrespective of the type of triggering, therefore, all the water-carrying parts of the ESA 1c are always flowed through, which together form the region 5c. The ESA lc thus does not have the potentially critical areas 5a-b.
    Advantageously, the ESH 4 stores the time of opening of the valve 10a and closes the valve 10a after a predetermined maximum run time of one minute, even if the actuator 12 is still open, thereby preventing overflow of the washbasin.
    4 shows with the ESA ld a further embodiment of the ESA lc. The ESA ld has the proximity sensor 13 with the response range 13a. The response range 13a is designed such that an object, for example the hand of a user, is reliably detected in the area below the outlet 9 and in front of it. The proximity sensor 13 is coupled to the ESH 4 which, in the presence of a hand in the response region 13a regardless of the position of the actuator 12, the valve 10a opens and thus triggers the ESA ld contactless. The proximity sensor 13 overrides the specification of the actuator 12 to the flow rate and the ESH 4 controls during use with the valve 10 a, the temperature of the mixed water PWM according to the temperature setting of the actuator 12 to a predetermined volume flow of example 6 1 / min, after a lapse predetermined lag time of exemplarily one second ends after the user has removed his hand from the response area 13a again. Volumetric flow and follow-up time are stored as parameters in the memory 17 and / or executed adjustable by means of adjustment.
    In an alternative embodiment, the ESH 4 controls during use with the valve 10 a, the temperature of the mixed water PWM to an independent of the position of the actuator 12, predetermined setpoint temperature of, for example, 38 ° C. The setpoint temperature is stored as a parameter in the memory 17 and / or executed adjustable by means of adjustment.
    Advantageously, the ESH 4 stores the time of opening of the valve 10a and closes the valve 10a after a predetermined maximum run time of 10 seconds, even if an object is still in the response range 13a of the proximity sensor 13 and thereby prevents not only overflow of the
    Sink, but also an unnecessary water consumption.
    The proximity sensor 13 detects the object preferably in visible light, in the infrared light (IR) having a wavelength in the range of 800 to 1000 nm, by means of electromagnetic waves (radar) with a frequency in the megahertz and gigahertz range, by means of sound waves (ultrasound) with a frequency over 20 kilohertz, or by measuring the absolute capacitance or capacitance change, using PIN diodes, PSDs, cameras, CCD sensors, CCTVs, antennas, microphones or electrodes.
    In further embodiments, the valve 10a is designed as a single-lever cartridge, as a solenoid valve, as a thermostatic valve, as a mixing valve, as a control valve, as a proportional valve, as a control valve, as a throttle valve or as a combination of these components.
    In an embodiment not shown as a further embodiment of the ESA lb with a proximity sensor 13, the ESH 4 opens and blocks the water flow when activated via the proximity sensor 13 not with the valve 10a, but with the valve 10b.
    5 shows with the ESA le an alternative embodiment of an ESA, which has a proximity sensor 13 for non-contact water delivery and the sensor 14 for detecting the temperature of the discharged water. The ESA le has the hose 6a, through which the supply of water takes place. The valve 10a is exemplified as a solenoid valve. The ESH 4 has the VSSE 16, which is an example of an electronic module. During the discharge of water, the VSSE 16 periodically, exemplarily 100 times per second, monitors the temperature of the discharged water detected by the sensor 14 and closes the valve 10a when the temperature exceeds a predetermined limit temperature of, for example, 42 ° C. The limit temperature is stored as a parameter in the memory 17 and / or made adjustable by means of adjustment.
    In a particularly advantageous embodiment, the VSSE 16 is designed as part of the program of the microcontroller 15.
    6 shows with the ESA lf an alternative embodiment of the ESA la with the coupled to the actuator 12, designed as a single-lever cartridge valve 10a. The valve 10b is exemplified as a bistable solenoid valve, coupled to the ESH 4 and in
    Initial state opened. The sensor 14 coupled to the ESH 4 is designed as a combined temperature / pressure sensor and arranged spatially between the valves 10a-b.
    The removal of water takes place as described in Fig.l. Furthermore, as described in FIG. 5, the ESA lf has a VSSE 16 which periodically monitors the temperature of the delivered mixed water PWM detected by the sensor 14 during the discharge of water, but closes the valve 10b if its temperature exceeds the predetermined limit temperature of, for example, 42 ° C exceeds. Subsequently, the ESH 4 periodically opens, for example once every 5 seconds, the valve 10b, the VSSE 16 monitors the temperature and pressure detected by the sensor 14 and immediately closes the valve 10b again when both the limit temperature of the mixed water PWM and a predetermined one Maximum pressure is exceeded by example 10 kPa above atmospheric pressure and so continues to block the delivery of mixed water PWM, whose temperature exceeds the limit temperature. If the valve 10a is closed with the actuating member 12, and the maximum pressure between the valves 10a-b is thus undershot when the valve 10b is opened by the ESH 4 or the mixed ratio of cold water PWC and hot water PWH is changed so that the limit temperature is not reached, this remains Valve 10b in the open state. The maximum pressure of 10 kPa by way of example is stored as a parameter in the memory 17 and / or made adjustable by means of adjustment.
    In an alternative embodiment, the ESA lf via a proximity sensor 13, not shown, for non-contact water delivery. In a particularly cost-effective embodiment of the sensor 14 is designed as a temperature sensor and the valve 10 a as a permanently open mixing valve, with the rotation of the actuator 12, the mixing ratio of the hot water PWH and cold water PWC is set. The release of the water flow for non-contact water delivery upon detection of an object with the proximity sensor 13 is performed by the ESH 4 with the valve 10b.
    7 shows the ESA lg and details of its fitting body 2 along the cutting planes A-E. For clarity, the seals are not shown. The valve 10a, which is arranged in the region 5a through which the actuator 12 flows only when it is manually removed, is designed by way of example as a single-lever cartridge and is coupled to the actuating device 12. The valve 10b, which is arranged in the region 5b through which the ESH 4 flows only when it is automatically purged, is designed, for example, as a magnetic valve with a coaxially concentrically arranged inlet 19a and outlet 19b through which flow is in the opposite direction.
    The approximately T-shaped channel 7a consisting of the channel 7av coming approximately vertically from below in the region 5a and the channel 7aH arranged approximately at right angles to it connects the hot water inlet of the valve 10a and the inlet 19a of the valve 10b via the tube 6a Hot water connection of the building
    Water installation and the approximately T-shaped channel 7b consisting of the approximately vertically from below in the region 5b channel 7bv and the approximately perpendicularly arranged horizontally extending channel 7bH the cold water inlet of the valve 10a and the inlet 19a of the valve 10b via the tube 6b the cold water connection of the building-side water installation. In both the manual removal with the actuator 12 as well as automatic flushing through the ESH 4 flowed through area 5c is located between the channels 7av-bv of the approximately vertically upwardly outgoing channel 7cv for the effluent mixed water PWM arranged with the arranged approximately at right angles thereto , horizontally extending channel 7cH forms the approximately T-shaped channel 7c and connects the mixed water outlet of the valve 10a and the outlet 19b of the valve 10b to the outlet 9 via the horizontally extending channel 7d arranged approximately at right angles thereto. The valve 10b facing the ends of the channels 7aH-bH are configured thread-shaped and closed with the two exemplified as adjusting screws closure devices 20a-b. By means of the closure device 20a, the mouth cross-section of the channel 7aH can be adjusted into the inlet 19a of the valve 10b and the closure cross-section of the channel 7bH via the closure device 20b. Thus, not only the two channels 7aH and 7bH are closed with the closure devices 20a-b, but also the cross sections for the inflowing cold water PWC and hot water PWH are set by adjusting. By adjusting the cross sections, the mixing ratio and the volume flow of the valve 10b are regulated with the closure devices 20a-b. The two backflow preventers 21a-b prevent a crossflow between hot water PWH in the channel 7aH and cold water PWC in the channel 7bH through the inlet 19a when the valve 10b is closed. For reasons of clarity, the valve 10b and its reception in the sectional plane E are not shown. Preferably, the two closure devices 20a-b are secured against disassembly. Examples of such fuses are the marking of the threads of the channels 7aH-bH or the closure devices 20a-b or the introduction of snap rings into the channels 7aH-fc> H ·
    In a particularly inexpensive to manufacture embodiment, the channels 7aH-cH as shown in the sectional plane A are designed so that they are arranged parallel to each other and as a continuous bore with a valve 10b to the valve 10a constant or gradually or continuously decreasing diameter drill and so can be produced in one step.
