The invention relates to a terminal sanitary fitting, in particular for showers, baths, washbasins, sinks, bidets, urinals and toilets, with an electronic circuit unit, a valve and at least one proximity sensor with at least two response areas, a preventive flushing unit for triggering a preventive Stagnationsfreispülung for flushing the Stagnationswassers immediately before the use of the terminal sanitary fitting includes.
Terminal sanitary fittings are faucets for removing water, in particular for showers, baths, sinks, sinks, bidets, urinals and toilets. They entail the danger that with prolonged non-use of such a fitting, for example, during closing or non-occupancy, microorganisms such as bacteria, fungi or amoeba, in the stagnant residual water of the valve or the supply line can multiply and lead to life-threatening diseases in humans can. According to a publication by the German Federal Environmental Agency, Legionella pneumophila alone cause between 20,000 and 32,000 diseases of pneumonia each year in Germany, up to 15% of the cases are fatal. An analysis of 40,000 samples taken in Germany in 2012 showed that in 37% of the samples Legionella spec. could be detected and 17% of the samples were above the statutory measure. Since Legionella pneumophila hardly multiply in the cold water, they are in the state of origin. · · · · · · · · · · · · · · ················································
Unlike Escherichia coli, enterococci and Pseudomonas aeruginosa not in the scope of the Austrian Drinking Water Ordinance and can therefore be included in the drinking water supplied by the drinking water supplier. At ideal water temperatures, Legionella pneumophila approximately double every 2 to 3 hours; apart from this ideal temperature, the proliferation proceeds more slowly; outside certain limits, the propagation is stopped or the microorganisms are killed.
Especially with the removal of hot water, the outlet is already heated by the dispensed mixed water and the inflowing hot water to the ideal for the propagation of Legionella pneumophila temperature of about 30 to about 40 ° C and then cooled depending on the room temperature. Legionella pneumophila multiply even at temperatures around 50 ° C and therefore especially in areas of hot water installation, where a minimum temperature of 60 ° C is not maintained. This concerns above all partial strands with cooling, stagnant hot water, the return of the circulation or plants that are operated for reasons of energy saving during business interruptions or even in continuous operation below the minimum temperature of about 60 ° C required for the killing of Legionella pneumophila. 3/98 31 · · · · · · · · · ····· ···········································································
The following diagram illustrates the propagation of Legionella pneumophila at a temperature in the range of about 30 to about 40 ° C. On the x-axis is the time in hours, on the y-axis the number of colony-forming units (CFU) per 100 milliliters is shown as a size for the quantification of microorganisms.

Based on an initial stock of 10 cfu Legionella pneumophila per 100 ml, the measure value of 100 cfu per 100 ml is reached after approx. 9 hours at a water temperature in the range of 30 to 40 ° C. With regular rinsing of, for example, every 3 hours, starting from an initial stock of 10 cfu per 100 ml, a value of 22 cfu per 100 ml can not be exceeded and it is a safe distance to the action value of 100 cfu per 100 4/98 • · * 4 : • • • • • ml ensured. A regular manual operation even when not in use is very complicated for the operator and hardly feasible outside the operating hours. Particularly in hygienically sensitive areas, for example in operating theaters or in institutions for immunocompromised people, the expense of regular manual operation and monitoring has a significant impact on operating costs.
Especially in times of increased environmental awareness and the desire for a reduction in operating costs, energy efficiency is the focus of planners, installers, operators and residents of buildings, apartments and the like. An essential basis for the optimization of energy efficiency is the recording of the lifecycle of construction, operation,
Disassembly and disposal consumed resources. The recording of the amount of heat consumed in the operation of buildings or apartments is known inter alia from the AT512141A1. A disadvantage of the existing solutions is that only the total amount of heat delivered a group of fittings, but not the amount of heat each individual sanitary fitting itself is detected. However, precisely this is necessary to set targeted measures to reduce the amount of heat consumed the individual sampling points and also allow the operators of commercial facilities, such as wellness facilities, a charge according to the amount of heat consumed. 5/98

Terminal fittings with a sensor device for non-contact detection of an object, such as the hand of a user or a person who is in front of the valve, and an electronic circuit unit for controlling the flow of water discharge and a triggering device for the water flowing through, inter alia, from AT404150B , AT412824B, DE1951132A1, DE10148675C1, EP2169123A1, EP0813636A1 and US5961095A. In addition, US2005150556A1 discloses a fitting which can be additionally operated by hand.
From US2004254746A1 and AT506792B1 devices are known, which automatically trigger a hygiene flush after a certain period of non-use and so rinse the stagnation water after a predetermined time, regardless of the risk of microbiological growth. A disadvantage of these systems is that they cause flushing even with little risk of microbiological growth and thus unnecessarily waste water.
EP2500475A2 discloses a flushing system for automatically flushing pipes. The purge system includes temperature sensors and electronic components for acquiring, storing, and evaluating data such as temperature, frequency of use, and the like. After evaluation of the determined measured values, a flushing of the line up to the flushing system is triggered if necessary. The disadvantage of this system is that the 6/98
Pipes are not rinsed by the flushing system to the terminal fittings and the terminal fittings themselves and so can multiply the microorganisms in these areas unhindered.
In GB2348945B it is described that in order to reduce the microbiological growth, in particular the multiplication of Legionella pneumophila, in warm water systems a temperature of the hot water of at least 60 ° C is usually to be maintained. The protection against scalding, especially in facilities for children and the elderly, is done by means of thermostatic valves, so that at the water delivery points a certain maximum temperature, for example in the range of 43 to 44 ° C, can not be exceeded. In order to kill the self-propagating germs in the thermostatic valves, the
Temperature limit be lifted by a service force, which is very expensive for the operator.
In DE102004014126B3 a fitting is described, in which a bypass is provided with a solenoid valve, via which the water can be passed bypassing the mixing device.
DE10156224C1 discloses a device for thermal disinfection of a sanitary fitting. The device includes a solenoid valve, which leads the hot water, bypassing the mixing device and the extraction valve in the mixed water pipe. 7/98

A disadvantage of this device is that the thermal disinfection takes place exclusively with hot water, bypassing the mixing device and mixed with hot water temperatures above the set temperature for the thermal disinfection no cold water and thus unnecessarily hot water is consumed.
A disadvantage of the solutions disclosed in DE102004014126B3 and DE10156224C1 is that the Legionella pneumophila itself propagating in the mixing device can not be killed, since the rinsing water having more than 60 ° C. for killing the Legionella pneumophila in the thermal disinfection does not damage the mixing device itself, but flows through a bypass and thus bypasses the mixing device.
DE29622320U1 describes a fitting with mixing device. To reduce legionella growth, if necessary, rinse the lines with hot water.
The disadvantage of this fitting is that the hot water is not supplied via the hot water inlet, but via its own hot water disinfection port, thus the strand end of the hot water pipe to the hot water inlet of the valve, and the hot water pipe and the mixing chamber in the valve itself are not flushed and allow the microorganisms in these areas to multiply unhindered. 8/98

EP2439174A1 discloses a flushing system for water pipes. The flushing system has facilities such as sensors, processors, memory and control software. Via radio or data line, the recorded parameters and rinses carried out can be transmitted to an external processing device. A disadvantage of this system is that only the hot water pipe is flushed through a bypass directly into the outlet and possibly located in the cold water pipe and the fitting itself microorganisms are not flushed out and they can multiply unhindered.
The W02009078004A2 describes a device for hot water supply. At least one sensor determines the temperature of the discharged hot water. The system can be programmed to dispense mixed water of a given temperature as hot water for terminal fittings. Anti-scalding closes the valve if the temperature of the mixed water delivered as hot water to the terminal fittings exceeds a certain threshold temperature. A disadvantage of this device is that the temperature of all connected terminal fittings is limited and even when needed by no terminal fitting mixing water can be delivered at a higher temperature. 9/98 • · 3 ····· ··· ····· t ·····················································
DE102009030543A1 describes a system with a central control device for the thermal disinfection of sanitary fittings. It allows a remote controlled triggering of a thermal disinfection and storage of the data. When operating an actuator during thermal disinfection, the thermal disinfection is stopped to protect the user. All controls and temperature sensors are wired via signal lines and all bypass valves via control lines to the central control device. Disadvantages of this system are the high costs and on-site expenses for the wiring.
From W09529127A1 a water treatment device is known. After the thermal disinfection, the hot water is drained.
WO02006077396A1 discloses an installation system in which, after a thermal disinfection, water is rinsed with a safe temperature for a predetermined time. The disadvantage of this system is that the temperature of the remaining water in the installation system is not taken into account.

US2005103693A1 discloses a non-terminal drinking water rinsing unit for filling tanks of means of transport such as airplanes, trains, buses, boats and ships with a temperature sensor for detecting the temperature in the interior of the drinking water rinsing unit and a nozzle for filling tanks and not for direct water extraction a user, for example, in showers, tubs, sinks, sinks, bidets, urinals and toilets. When a limit temperature in the interior of the drinking water flushing unit is exceeded or a stagnation period is exceeded, a control unit triggers a valve and flushes the stagnation water from the drinking water flushing unit through a stagnation flush outlet into a drain. A disadvantage of this solution is that the flushing out of the stagnation water is carried out by an additional valve to which the usual dispensing valve is coupled and that in the terminal sanitary fittings for direct water withdrawal by a user stagnant water in the course of flushing out the stagnation water from the drinking water rinse the terminal sanitary fittings is flushed out and so can multiply the microorganisms in the terminal plumbing fixtures unhindered.

To determine the stagnation time, the position of the door of the drinking water flushing unit is monitored with a sensor. If the door is opened, this is considered as use and the electronic counter of the stagnation period is reset, although it is not ensured that water is withdrawn each time the door is opened. In addition, the temperature of the interior of the drinking water rinse unit increases considerably faster than the temperature of the stagnation water when exposed to heat, whereby the Stagnationsfreispülung triggers early and unnecessary water is wasted.
From DE102008039272A1 a method for determining the resource consumption at a water tap is known. By means of flow meter, temperature sensor and microcontroller, the amount of heat is determined. A disadvantage of this method is that the resource-saving use is ensured only by intervention of the user or by means of additional components.

At the top of the fitting body 2 is mounted opposite the fitting body 2 about the vertical axis 11a rotatably mounted dash cover 11, which carries the actuating lever designed as a pivoting actuator 12. The dashboard cover 11 includes a position sensor 11b, which detects, on the one hand, a rotation of the dashboard cover 11 and, on the other hand, pivoting of the actuator 12 from the position 12a to the stop in the position 12c and transmits the values as electrical signals to the electronic circuit unit 4 mounted in the fitting body 2 , On the underside of the fitting body 2 are the connections for hot water WW and cold water KW, in whose openings each a backflow preventer is inserted. About the hot water hose 6 and the cold water hose 7, the terminal plumbing fixture 1 is connected to the building-side water installation 17/98, not shown. In the sanitary fitting 1 designed as a mixing valve valve 30 is arranged. The valve 30 comprises the valve body 34, the hot water inlet 37 for inflowing hot water WW, the cold water inlet 39 for incoming cold water KW and the mixing chamber 38 with the mixed water outlet 45 for the dispensed mixed water MW, which flows via the outlet pipe 10 into the outlet 9. Furthermore, the valve 30 includes the electric motor 31, which forms the actuator for the inflowing hot water WW with the adjusting screw 32 vertically adjustable via the thread 33, wherein the stroke Hl between the stopper 36 and the seal 35, the volume flow of hot water flowing through WW in the direction of mixing chamber 38 determined. On the cold water side, the electric motor 44 forms the actuator for the inflowing cold water KW with the adjusting bolt 43 vertically adjustable via the thread 42, wherein the stroke H2 between the stop 40 and the seal 41 determines the volume flow of the cold water KW flowing through in the direction of the mixing chamber 38. In the illustrated position for the stroke Hl and the stroke H2 results in a mixing ratio for the delivered mixed water MW of about 30% hot water WW and 70% cold water KW. The temperature sensor 22 in the region of the mixed water outlet 45 detects the temperature of the stationary and the flowing mixed water MW and forwards them as an electrical signal to the circuit unit 4. The sanitary fitting 1 further comprises a battery as a power supply 3 and a control line 23 for 18/98.

Activation of the disinfecting rinse of the sanitary fitting 1, in particular a thermal disinfection (see Fig. 4).
The electronic circuit unit 4 is designed as a PID controller for controlling the temperature and the volume flow of the mixed water MW with the setpoint specification of the temperature by the position of the valve cover 11 and the setpoint value of the volume flow through the position of the actuator 12. The electronic circuit unit 4 controls the Valve 30 such that the actual temperature and the volume flow of the mixed water MW in the outlet 9 correspond to the respective setpoints.
In the position 12a of the actuator 12, the electronic circuit unit 4 controls the valve 30 so that the delivery of mixed water MW is interrupted and the sanitary fitting 1 is closed. To trigger the sanitary fitting 1, the user pivots the actuator 12, starting from the position 12a upwards. The position sensor 11b detects the pivoting movement and transmits it to the electronic circuit unit 4, which controls the valve 30 such that the sanitary fitting 1 emits the minimum volume flow of the mixed water MW from the outlet 9.

In the position 12c, the maximum volume flow of mixed water MW from the Spout 9 delivers. If the actuator 12 is pivoted downward, the electronic circuit unit 4 controls the valve 30 such that the volume flow of the mixed water MW delivered is reduced and in the position 12 a the delivery of mixed water MW is interrupted and the sanitary fitting 1 is closed again.
If the actuator 12 is rotated clockwise to the left, so the position sensor 11 b passes the rotation of the dash panel 11 about the vertical axis 11 a to the electronic circuit unit 4 and this controls the valve 30 so that the temperature of the mixed water MW delivered is raised and left stop 12d does not exceed a predetermined limit of example 38 ° C. This prevents the scalding of a user with mixed water MW at too high a temperature. If the actuator 12 is rotated counterclockwise to the right, the electronic circuit unit 4 controls the valve 30 so that the temperature of the mixed water MW delivered is lowered and corresponds to the inflowing cold water KW in the right stop 12e.
The electronic circuit unit 4 has a microcontroller control with a predetermined delay time, which delays the closing of the sanitary fitting 1 by a user.

Due to the continuous decay of the water jet 21 during the closing time, the emergence of pressure peaks in the sanitary fitting 1 is prevented by the closing operation. The temperature of the Stagnationswassers 46 corresponds to the time of closing the temperature of the mixed water delivered MW and gradually equalizes the temperature of the ambient air surrounding the valve of example 24 ° C. If microorganisms were introduced into the fitting with the inflowing cold water KW or the inflowing hot water WW or if microorganisms penetrate through the jet regulator 8 and the outlet pipe 10 into the region of the stagnation water 46, they can multiply in the stagnation water 46, the rate of propagation essentially being dependent on the temperature the stagnation water 46 and the supply of nutrients in the stagnant water 46 is determined.
The follow-up time is given by way of example with a tenth of a second, so that the sanitary fitting 1 quickly stops the delivery of mixed water MW when the actuator 12 is brought into the position 12a 21/98 > · · · · · · · · · · · · · · · · · · · · ··············································. Alternatively, the follow-up time is given by way of example with three seconds. Thus, a user who touches the sanitary fitting 1 to close, then clean the hands again, the valve 30 is controlled by the electronic circuit unit 4 so that the temperature of the delivered mixed water MW and the resulting stagnation water 46 corresponds to a predetermined value , The delay time and the closing time are specified in the program of the microcontroller control. In a particularly advantageous embodiment, at least the follow-up time or the closing time is executed adjustable with an adjustment knob or a remote control. The predetermined value for the temperature of the forming stagnation water 46 is the temperature of the inflowing cold water KW. In another embodiment, the predetermined value for the temperature of the forming stagnation water 46 is included in the program of the microcontroller or executed adjustable with an adjustment or a remote control. The adjustment knob is exemplified as a potentiometer, a slider, a wheel, a joystick, a DIP switch, a rotary switch, or a tap changer.
In an alternative embodiment, the valve cover 11 of the sanitary fitting 1 is rigidly connected to the fitting body 2.

In the position 12a of the actuator 12, the electronic circuit unit 4 controls the valve 30 so that the delivery of mixed water MW is interrupted and the sanitary fitting 1 is closed. To trigger the sanitary fitting 1, a user pivots the actuator 12, starting from the position 12a upwards. The electronic circuit unit 4 controls the valve 30 such that the sanitary fitting 1 emits the minimum volume flow of the mixed water MW with a predetermined temperature of example 35 ° C from the outlet 9. If the actuating member 12 is pivoted further upwards, then the electronic circuit unit 4 controls the valve 30 such that the volume flow of the mixed water MW delivered is increased and in the position 12c the maximum volume flow of mixed water MW is emitted from the outlet 9. If the actuator 12 is pivoted downward, the electronic circuit unit 4 controls the valve 30 so that the volume flow of the delivered mixed water MW is reduced and in the position 12a, the delivery of mixed water MW is interrupted and thus the sanitary fitting 1 is closed again.

To trigger the sanitary fitting 1, a user pivots the actuator 12, starting from the position 12a upwards. The electronic circuit unit 4 controls the valve 30 such that the sanitary fitting 1 emits the minimum volume flow of the mixed water MW with a predetermined starting temperature of example 25 ° C from the outlet 9. If the actuating member 12 is pivoted further upwards, then the electronic circuit unit 4 controls the valve 30 such that the volume flow of the mixed water MW delivered is increased and in the position 12c the maximum volume flow of mixed water MW is emitted from the outlet 9. If the actuator 12 is pivoted downward, the electronic circuit unit 4 controls the valve 30 such that the volume flow of the mixed water MW delivered is reduced. In the microcontroller control contained in the electronic circuit unit 4 is a program schedule with times and temperatures, for example, 25 ° C for 20 seconds for wetting the hands before soaping followed by 60 seconds 38 ° C for cleaning the hands deposited.

In a particularly advantageous embodiment, the times and / or temperatures are designed to be adjustable with at least one setting controller or a remote control.
In another embodiment, the sanitary fitting 1 is designed so that the actuating member 12 is rigidly connected to the valve cover 11. With the actuator 12, the temperature of the mixed water MW is adjusted by rotating the dash panel 11 about the vertical axis 11a. The flow meter 45a in the mixed water outlet 45 detects the flow of the outflowing mixed water MW and passes the measured values as electrical signals to the electronic circuit unit 4, which determines the volume flow of the mixed water MW delivered in liters per minute. In stop 12d of the actuator 12 controls the electronic circuit unit 4, the valve 30 such that the delivery of mixed water MW interrupted and the sanitary fitting 1 is closed. If the actuator 12 is rotated counterclockwise to the right, so controls the electronic circuit unit 4, the valve 30 such that the flow rate of 25/98 delivered mixed water MW a predetermined value of example 6 liters per minute and the temperature of the discharged from the outlet 9 Mixed water MW corresponds to a predetermined minimum temperature of 25 ° C by way of example. If the actuator 12 is further rotated counterclockwise to the right, the electronic circuit unit 4 controls the valve 30 so that the temperature of the mixed water MW delivered is increased and in the right stop 12e, the temperature of the mixed water MW discharged from the outlet 9 a predetermined limit , not exceeding 38 ° C, does not exceed. This prevents scalding of the user with mixed water MW at too high a temperature. If the actuator 12 is rotated clockwise to the left, so controls the electronic circuit unit 4, the valve 30 so that the temperature of the mixed water MW discharged is lowered and the left stop 12 d the delivery of mixed water MW interrupted and the sanitary fitting 1 is closed.
