Description

The present invention relates to a flushing device according to the preamble of claim 1, 8 or 13, a system according to the preamble of claim 16, a method and a use.

The invention relates to the automatic implementation of hygienic flushes in a drinking water system.

Drinking water is subject to strict hygienic regulations and limit values. When complying with the regulations, it can be problematic if pipes for the drinking water are temporarily not used, for example if an apartment is vacant for a long period of time or individual rooms in a hospital or hotel are not occupied for a few days. In such cases, the water in the pipes stagnates. This can cause contamination, especially Legionella and Pseudomonads.

The operators of real estate, hospitals, holiday homes, hotels, old people's homes or the like, for example, are legally obliged to comply with the regulations for drinking water or to provide drinking water for human consumption and / or to comply with the intended use.

Carrying out so-called "hygiene flushes" ensures that the water quality in the pipes meets the requirements for drinking water. During a hygiene flush, the water in the pipes is exchanged so that "old" water is flushed out of the pipes and replaced with fresh water or drinking water. In particular, water is drained off at the end of the service so that water flows in from a main supply line, which often supplies several buildings with water, until the water has been completely replaced.

Hygiene flushing can be carried out manually, for example by opening fittings manually every two to three days and thus replacing the water in the pipes with fresh water. However, this procedure is uneconomical, complex and often does not meet the requirements for correct hygienic flushing.

However, solutions for automatically performing hygienic flushes are also known from the prior art.

From the EP 1 964 983 A1 a flush-mounted device for performing hygienic flushes is known. The flush-mounted device is connected to a hot water line and to a cold water line of a pipeline system. Controllable solenoid valves, which are connected to the pipelines, are arranged within a housing of the device. When the valves are opened, the water flows from the pipelines into a siphon and from there via a nozzle into a disposal line of the pipeline system. The device has the disadvantage that it has to be permanently installed in a pipeline system and is unsuitable for temporary or short-term use, for example in a hotel room or the like that has been empty for a few days.

From the EP 3 363 956 A1 a device for automatically performing hygienic flushes is also known. The device comprises a valve unit and a drain housing unit. The valve unit comprises an inlet connector for connection to the water line, an outlet connector and a valve arranged between the inlet connector and the outlet connector. The outlet connector ends in the drain housing unit, so that water can be discharged from the outlet connector into the drain housing unit, which forms an odor trap. The drain housing unit is connected to a sewage network.

From the DE 10 2013 102 567 A1 a device for performing hygiene flushes is known, which can be detachably connected to a water dispensing device. The device has a valve and a controller for programmable opening and closing of the valve. The devices can also include a temperature sensor, the measured temperature being taken into account in the control.

From the DE 10 2014 201 909 A1 an automatic flushing device for arrangement at a water extraction point of a water pipe system is known. A control device opens and closes a controllable valve after certain interval times and / or flushing times. The flushing device has a flow meter so that the controller can also close the controllable valve after a defined flushing amount that has flowed through the valve.

The known devices are each permanently installed in a building or a pipeline system. This installation is relatively complex and must be carried out by a specialist. A device that is easy to install and uninstall, which can be used comfortably in particular for a period of a few days or weeks, is therefore desirable.

Another disadvantage of the known devices is that it is provided in each case to connect the devices to a sewage or disposal line. The devices are therefore each equipped with a siphon or odor trap and accordingly have a relatively complicated structure.

In addition, another disadvantage of the known devices is that they cannot be used on tubs or showers. It is therefore not possible to carry out hygienic flushes on these devices. A hygienic flushing of showers and tubs is extremely desirable, since Legionella cause Legionnaires' disease in particular when they are inhaled, for example when showering or bathing.

It is an object of the present invention to specify a flushing device, a system and a method for performing hygienic flushing and the use of a flushing device, whereby simple and / or quick assembly or installation, simple operation and / or safe operation are made possible and / or to specify a flushing device and a system for performing hygienic flushing, which are characterized by a simple and / or compact structure.

The above object is achieved by a flushing device according to claim 1, 8 or 13, a system according to claim 16, a method according to claim 17 or a use according to claim 18 or 19. Advantageous further developments are the subject matter of the subclaims.

According to a first aspect, the present invention relates to a flushing device for automatically performing hygiene flushing in a drinking water system. The flushing device preferably has a temperature sensor for measuring the temperature of the water flowing through the flushing device during a hygienic flush.

The flushing device is preferably designed to use the temperature sensor to determine temperature profiles of separate hygiene flushings carried out with the flushing device and to determine deviations between the temperature profiles. This enables, for example, the adaptation of the duration of hygienic flushing on the basis of the temperature profiles or the detection of leaks or damage in the drinking water system. In particular, safe operation is thus made possible.

The flushing device preferably has - in addition to the temperature sensor for measuring the temperature of water that passes through the flushing device during a hygienic flush - an ambient temperature sensor for measuring the ambient temperature. Furthermore, the flushing device is preferably designed to recognize an anomaly based on a comparison of measured values of the temperature sensor for measuring the water temperature with measured values of the ambient temperature sensor, in particular to detect a failure of a heating device or a risk of pipe breakage. Here, the heating device can be a heating device of the drinking water system, for example a boiler or the like for heating water in the drinking water system, but alternatively or additionally also another heating device such as a heater in a building with the drinking water system that is separate from the drinking water system. If a heating device fails, water in the drinking water system can freeze, especially in winter. Damage to the drinking water system can therefore be avoided if it is recognized in good time that a heating device has failed.

The flushing device is preferably designed to generate, output and / or transmit a message, in particular a warning, when a deviation between different temperature profiles fulfills at least one test criterion. In this way, a user of the flushing device can be made aware of problems in good time, so that safe operation of the flushing device is enabled and damage to the flushing device or the drinking water system can be prevented.

The deviation between temperature profiles can consist, for example, in the fact that after a shorter time than with one or more previous temperature profiles or hygienic flushes, a predetermined or specifiable threshold value for an (absolute or relative) temperature, temperature difference, a profile of the temperature and / or a rate of temperature change is reached or is fallen below or an - at least essentially - constant temperature is reached. Such a deviation can be an indication or used as an indicator that there is a leak in the drinking water system, so that safe operation is made possible by the notification.

The flushing device is preferably designed to detect a leakage and / or damage, in particular a broken pipe, in the drinking water system and / or a failure of a heating device, in particular the drinking water system, on the basis of deviations between temperature profiles. This enables safe operation.

The message, in particular a warning, is preferably an acoustic and / or optical signal and / or the message or warning to an external device, in particular a server, is a mobile terminal or an operating device, can be transmitted. The flushing device is therefore preferably designed to output the message, in particular in the form of an acoustic or optical signal and / or by transmitting the message to an external device. By transmitting to an external device, an operator or user of the flushing device can preferably be informed or warned immediately, so that safe operation is made possible by the message.

The message, in particular a warning, is preferably generated or transmitted on the basis of the comparison of the temperature profiles or a leak identified thereby. Alternatively or additionally, the message can have the result of a comparison between temperature profiles and / or an indication of a possible leak.

The flushing device preferably has a pressure sensor. Here, the flushing device is preferably designed to detect a pressure anomaly, a leak and / or damage, in particular a broken pipe, in the drinking water system on the basis of a temperature profile and a pressure or pressure profile measured by the pressure sensor. In particular, the pressure or a pressure profile with the flushing device closed is evaluated in order to determine the pressure anomaly. Alternatively or additionally, the pressure curve can be evaluated, which is measured when the flushing device is opened or opened or during a flushing process. In a particularly preferred embodiment of the present invention, the identification of a pressure anomaly is combined with the result of a comparison of temperature profiles of different flushing processes, in particular as described above. Furthermore, the flushing device is preferably designed to generate, output and / or transmit a message, in particular a warning, upon detection of a pressure anomaly, possibly with additional determination of the indicator based on the comparison of temperature profiles. This is beneficial to the safety when operating the flushing device and / or the drinking water system.

The flushing device is preferably designed to determine a temperature difference between the measured values of the temperature sensor for the water in the drinking water system and the ambient temperature sensor during a hygienic flush and to evaluate the temperature difference, in particular a temperature difference maximum, with a test criterion. In this case, the flushing device is preferably further designed to generate, output and / or transmit a message, in particular a warning, as a function of the temperature difference. This is beneficial to the safety when operating the flushing device and / or the drinking water system.

According to a further aspect, which can also be implemented independently, the present invention relates to a flushing device for automatically performing hygienic flushing in a drinking water system, the flushing device having an electrically controllable, bistable valve and being designed so that when the valve is opened, water exits the flushing device and at Closing the valve prevents water from escaping from the flushing device. A bistable valve is, in particular, such a valve that, due to its design, has to be activated to open and close, but not in order to maintain an open or closed state. A bistable valve that has been opened once therefore preferably remains stable in the open state until it is activated again to close. Furthermore, a bistable valve preferably remains in a closed state without this requiring continuous activation.

The flushing device preferably has an energy supply device for a control energy supply and an emergency energy supply device which is separate from the energy supply device and by means of which the valve can be closed in the event of failure of the energy supply device or control energy supply. This is beneficial to the safety when operating the flushing device or the drinking water system.

The emergency energy supply device preferably has an electrical energy store which can be charged by the energy supply device and, in order to close the valve, can be or is connected to the valve separately from the energy supply device. This is beneficial to the safety when operating the flushing device or the drinking water system.

This is conducive to a particularly compact design of the flushing device. The hole is very particularly preferably a blind hole. On the one hand, the hole can be formed in that the fluid channel at the end of the hole means that the hole is not continuous. Alternatively or additionally, the depth of the hole can be limited by an annular shoulder which can form a sealing surface. In this case, the end of the blind hole can have an opening to the fluid channel.

Preferably, the hole or holes each have a thread for connection to the valve and / or the sensor and the valve and / or the sensor can be screwed into the hole or one of the holes. As a result, the flushing device can be manufactured particularly easily or put into an operational state. Furthermore, a simple replacement or repair of the valve and / or the sensors or the flushing device is made possible.

Preferably, the hole or holes each have a sealing surface for sealing the valve or valve head and / or sensor (s). The hole can have a radially extending shoulder on which a sealing ring can be arranged between the valve and / or sensor and the sealing surface. Alternatively or additionally, the sealing surface of the respective blind hole can also be provided radially, so that a sealing ring is provided between the valve or valve head and / or sensor and a radial circumferential surface of the (respective) blind hole, around the valve, the valve head and / or the sensor to be sealed against the housing. However, other solutions for the corresponding sealing are also possible here.

The blind hole or holes preferably have a bottom or end opening to the fluid channel.

In particular, this corresponds to an automatic switch-off and switch-on of the flushing device 3rd (based on the pressure).

Preferably the flushing device is 3rd designed to switch on when the pressure exceeds a threshold value and / or switch off when the pressure falls below a threshold value. In this way it is not necessary to use the flushing device 3rd after connecting to the outlet fitting 2 switch on, but switch on the flushing device 3rd can be done automatically or by the flushing device 3rd take place themselves, in particular by water pressure when opening the valve or valves 2C the outlet fitting 2 .

This open space is preferred by the basin 8th limits which water can be released or released and via a drain 8A to a sewerage system. If this drain 8A Blocked completely or partially, it can happen that in the pelvis 8th the water level L. and possible overflow of the pool 8th threatens. The level sensor 10D is designed against this background to a fill level of the water level L. to detect or recognize.

The flushing device 3rd is further preferably designed to be stopped, preferably fully automatically, as a function of the fill level.

It is preferred that the housing 19th is formed from a solid material, the fluid channel K represents a hole or a recess or a channel in the solid material. In particular, the fluid channel K not by one in the case 19th arranged pipe or one in the housing 19th arranged hose formed.

Preferably the valve is / are 9 and / or one or more of the sensors 10 from an outside of the housing 19th out of such a way with the housing 19th connectable or connected that a valve head 9A of the valve 9 and / or the sensor (s) 10 between the inlet 6th and the outlet 7th with the fluid channel K are in operative connection.

Preferably the valve is 9 or the valve head 9A such in the housing 19th can be arranged or with the housing 19th connectable or connected that the valve head 9A into the fluid channel K protrudes and / or the fluid channel K with the valve 9 or valve head 9A Can be closed so that no water passes through the valve 9 can happen. The case 19th preferably forms a valve seat for the valve head 9A of the valve 9 .

Under an "operative connection" with the fluid channel K is understood in particular an arrangement or connection such that the sensors 10 each can fulfill their function. For example, the temperature sensor is standing 10C then in operative connection with the fluid channel K when the temperature sensor 10C is arranged so that with the temperature sensor 10C the temperature of the water in the fluid channel K is measurable. The pressure sensor 10A and / or volume flow sensor 10B are then preferably in operative connection with the fluid channel K when a pressure or a volume flow of the water in the fluid channel K with the corresponding sensor 10 is measurable.

Below are some preferred embodiments of the flushing device 3rd or control 12th carried out or feasible procedures described, which can be implemented independently, but also in any combination. The system 1 or the flushing device 3rd is preferably designed in each case to carry out the method aspects described.

In one aspect, the controller is 12th or rinsing device 3rd designed to, in particular on the basis of with the pressure sensor 10A measured data, pressure fluctuations in the drinking water system 4th or the fluid path F. to recognize. So can by means of the pressure sensor 10A Irregularities, in particular broken pipes or the like, can be recognized. This is the rinsing device 3rd especially for monitoring the drinking water system 4th educated. Optionally, the flushing device 3rd can thus be used to monitor vacant houses, apartments or rooms.

According to a further aspect, the volume flow sensor 10B the volume flow of the through the flushing device 3rd measured in flowing water. On the basis of the data determined in this way, for example by means of the controller 12th measured or checked what amount of water or what volume in the drinking water system 4th was or is replaced during a hygienic flush.

By means of the control 12th can open and close the valve 9 being controlled. For example, it is possible to use the valve 9 to close or end the hygienic flush when a certain volume of water has reached the flushing device 3rd has gone through. This water volume can, for example, be the volume in the drinking water system 4th absorbable water correspond so that the valve 9 is closed when the water in the Drinking water system 4th has been completely replaced and the hygienic flush is or can be ended.

According to a further aspect, the flushing device recognizes 3rd or control 12th based on data from the temperature sensor 10C whether and / or when or after what time or flushing duration a correct hygienic flush was carried out and / or the flush ended or the valve 9 can be closed. In particular, the temperature of the flushing device is constant or not (significantly) changing 3rd running water indicates that the hygienic flush was carried out correctly and / or that the water in the drinking water system 4th has been completely replaced.

In the drinking water system 4th The water in the room takes on the ambient temperature after a while and can be very warm in summer and / or very cold in winter, for example. In particular, the temperature of in the drinking water system 4th stagnant water from the temperature of the drinking water system 4th differentiate the water supplied. If now by the temperature sensor 10C no temperature change in the water that the flushing device 3rd is measured, this is an indication that this is in the drinking water system 4th stagnant water has been completely replaced by fresh water and the hygiene flush can be stopped.

In this way, the flushing device 3rd automatically determine a volume and / or a time after which the content of the drinking water system 4th is completely replaced.

This volume determined by means of the temperature profile and / or the time determined by means of the temperature profile (opening duration of the valve 9 ) can then be used to control the valve in the future 9 be used, even if a temperature profile, for example in winter, an accurate detection of the complete exchange of the water in the drinking water system 4th shouldn't allow. The proposed flushing device 3rd can therefore be self-learning to the extent that, via the determination and analysis of a temperature profile in a rinsing process by the rinsing device 3rd Flowing water target values for other control criteria are determined on the basis of which the valve 9 by means of the controller 12th is then controlled alternatively or additionally.

According to a further aspect, the flushing device 3rd controlled by a level. The filling level is, in particular, the water level L. in the flushing device 3rd associated basin 8th . The controller preferably recognizes 12th based on data from the level sensor 10D a certain fill level or water level L. or reaching or exceeding such a specific fill level or water level L. . When the controller 12th this fill level or water level L. recognized, it can control the valve 9 close or control in such a way that a hygiene flush is stopped and / or future hygiene flushes are prevented. In this way it can be prevented that a process is completely or partially blocked 8A of the pelvis 8th the water level L. through out the outlet 7th released water rises and possibly overflows the basin 8th leads.

According to a further aspect, the controller recognizes 12th based on data from the level sensor 10D falling below a certain level or water level L. or a drop in the water level L. . When the controller 12th has recognized such a drop or undershoot, this can be done by the valve 9 open again or control in such a way that a hygiene flush is continued and / or future hygiene flushes can be carried out. In this way, the flushing device 3rd can be automatically restarted or the hygiene flushing can be continued automatically if a process is blocked 8A a basin 8th is or was canceled again.

According to a further aspect, the data from different hygiene flushes are recorded and preferably compared with one another, in particular by means of the controller 12th . On the basis of the measured data or on the basis of the comparison between measured data of different flushing processes, settings for performing future hygienic flushes can be made and / or changed.

For example, it can be ascertained that in the case of several hygienic flushings, a constant and / or the same temperature in the flushing device after the same time 3rd water flowing through is measured. As this - as explained above - indicates that the water in the drinking water system 4th has been completely replaced and thus the hygiene flushing can be ended, the control can 12th Specify or change the settings for performing the hygiene flush in such a way that the valve 9 is automatically closed after this or a time oriented towards this, and preferably also when the water temperature is permanently constant or changes atypically in some other way. In this way, for example, water can be saved when performing hygienic flushing and / or the settings for the hygienic flushing can be optimally adapted to the respective drinking water system 4th be adjusted. This is particularly advantageous for the use of the Rinsing device 3rd in various drinking water systems 4th , for example in different houses.

Preferably the flushing device is 3rd designed to provide further information, such as a state of charge of the energy store 13th or another device status, by means of the display device 17th display and / or by means of the data interface 14th to the control device 16 to submit.

The flushing device 3rd is preferably designed to work with the temperature sensor 10C Temperature curves of separate, with the flushing device 3rd to determine the hygienic flushes carried out. In particular, the flushing device 3rd designed to be used at different times during a hygiene flush with the temperature sensor 10C the temperature of the water in the flushing device 3rd to eat.

The flushing device 3rd is preferably also designed to determine deviations between the different temperature profiles. The flushing device 3rd is preferably designed to compare a temperature profile with several other temperature profiles or to determine deviations from one temperature profile to several other temperature profiles.

For this purpose, the with the temperature sensor 10C measured temperatures are preferably stored, in particular together with the times corresponding to the respective temperatures at which the temperature was measured. The time of a temperature measurement is preferably made with the timer 15th certainly.

A deviation between temperature profiles is preferably determined by comparing the temperature profiles. In this case, the temperatures are preferably compared after different flushing times in a hygienic flush. For example, the temperature can be measured for each hygiene flush at the same intervals, for example every five or ten seconds, and the temperatures of different hygiene flushes measured after the same flushing times can be compared with one another to determine deviations between the temperature profiles.

The flushing device 3rd is preferably designed to generate, output and / or transmit a message, in particular a warning, when a deviation between temperature profiles fulfills at least one test criterion.

The message or warning preferably has an acoustic and / or optical signal or is formed thereby. In particular, the flushing device 3rd thus designed to output an acoustic and / or optical signal or warning signal when a deviation between temperature profiles meets at least one test criterion.

The acoustic signal can be or have, for example, a beeping, a repeating signal, a melody, a voice output or the like.

The optical signal can be or have, for example, a permanently shining or flashing light and / or the display of a text or the like. The flushing device is preferably for outputting the (optical) signal with the display device 17th educated.

Alternatively or additionally, the message or warning is sent to an external device, in particular a server 21 , a mobile device such as a cell phone or smartphone, a laptop or a tablet, can be transmitted or is the flushing device 3rd designed to transmit the message or warning to such an external device.

The above-described operating device is particularly preferably the external device 16 . The transmission to the server 21 and / or the external device is preferably wireless.

As a test criterion for a deviation between temperature profiles, for example, reaching or exceeding a predefined or predefinable temperature at the end of the hygienic flush and / or at a specific point in time during the hygienic flush can be provided.

Alternatively or additionally, a maximum temperature difference between two temperature profiles at a specific point in time or a specific flushing duration can be provided as a test criterion.

According to a further example, a threshold value for a temperature change rate (temperature change per time) can be predefined or predefinable as a test criterion. In particular, the deviation can consist in the fact that a constant temperature or a small temperature change or rate of temperature change is reached after a shorter time than in the case of one or more previous temperature profiles. Correspondingly, the test criterion is met in particular if the threshold value is reached or fallen below in a temperature profile or a hygienic flush after a shorter time than in one or more previous temperature profiles or hygienic flushes.

In particular, the test criteria mentioned can also be combined and / or further test criteria can be provided, for example a test criterion according to which it is checked how quickly the temperature changes with a temperature profile in order to avoid unexpected events or profiles and / or other anomalies or temperature anomalies to recognize.

By determining deviations between temperature profiles, for example, hygienic flushes can be optimized by adapting or changing the duration of the hygienic flush on the basis of the determined deviation.

Furthermore, a deviation between temperature profiles can indicate a change in the drinking water system 4th or in the vicinity of the drinking water system 4th be. For example, a deviation between the temperature profiles can be an indication that the drinking water system 4th has a leak through which water leaks. In this case, a constant temperature is usually reached after a shorter period of time in a hygienic flush than in an earlier hygienic flush in which the drinking water system 4th has not yet had a leak, because the leak is the amount of when not in use in the drinking water system 4th standing water decreased. Typically this has the drinking water system 4th that is, the water supplied has a different temperature than that in the drinking water system 4th standing water when not in use.

However, a deviation between temperature profiles can also be an indication of a failure of a heating device. When the flushing device 3rd via the outlet fitting 2 is connected to a hot water pipe, the failure to reach a temperature reached in one or more previous hygienic flushes or temperature profiles can be an indication that a heating device for heating water in the drinking water system 4th or for the provision of hot water has failed or is not working properly. A changed temperature at the beginning of a temperature profile or a hygiene flush can be an indication of the failure or improper function of a heating system in a building with the drinking water system 4th be. For example, it can be provided that a building with the drinking water system 4th by means of - in particular from the drinking water system 4th separate - heating is kept at a minimum temperature, for example to prevent pipes or the drinking water system from freezing 4th to prevent. If the heating has failed, it is possible that the temperature of the water in the drinking water system 4th and thus at the beginning of a hygienic flush or a temperature profile drops below the temperature in a previous hygienic flush or a previous temperature profile. This can represent a discrepancy between temperature curves. In particular, the flushing device 3rd designed to generate, output and / or transmit a message or warning in this case.

The flushing device 3rd is preferably designed to detect a leak and / or damage in the drinking water system, in particular a broken pipe, or a risk of leakage and / or damage - for example through freezing of the drinking water system - based on the deviation between temperature profiles 4th or lines thereof - to be recognized. In particular, the flushing device 3rd designed to generate, output and / or transmit a message or warning in the event of such a detection.

As an alternative or in addition, the flushing device is available 3rd designed to recognize a failure of a heating device on the basis of the deviations between temperature profiles. Here, the heating device can be a heating device of the drinking water system 4th which is designed to heat the water in the drinking water system, for example a boiler. However, it is also possible that the heating device is one of the drinking water system 4th is a separate heating device, for example a heater for the building in which the drinking water system is located 4th is located. In particular, the Rinsing device 3rd designed to generate, output and / or transmit a message or warning in the event of a failure of a heating device.

According to an aspect that can also be implemented independently, the present invention therefore relates to the use of the flushing device 3rd for monitoring the function of at least one heating device.

According to a further aspect that can also be implemented independently, the present invention also relates to the use of the flushing device 3rd to detect a leak and / or damage in the drinking water system 4th .

The flushing device 3rd is preferably designed to be based on a temperature profile and one with the pressure sensor 10A measured pressure or pressure profile, a pressure anomaly, a leak and / or damage, in particular a broken pipe, in the drinking water system 4th to recognize. For example, a sudden drop in pressure or a lower pressure than in one or more previous hygiene flushes can be an indication of a leak and / or damage, in particular a broken pipe, in the drinking water system 4th be. In order to detect a leak and / or damage, it has proven to be particularly reliable and therefore advantageous, on the one hand, especially with the temperature sensor 10C measured - temperature curve or a deviation of a temperature curve of a hygienic flush from previous temperature curves and on the other hand one with the pressure sensor 10A measured pressure or pressure curve to be used. In this way, in a synergistic manner, incorrect assessments which are based only on a temperature profile or a pressure or pressure profile can be avoided. It has been shown that in the event of a leak or damage, deviations in the temperature profile and deviations in the pressure or pressure profile usually go hand in hand with one another.

In particular, the flushing device 3rd designed to generate, output and / or transmit a message or warning when a leak and / or damage is detected.

As described above, the flushing device 3rd - in particular in addition to the temperature sensor 10C for measuring the temperature of the water in the flushing device 3rd or the fluid channel K - an ambient temperature sensor 10E exhibit. The flushing device 3rd is then preferably designed to detect a temperature difference between the measured values of the temperature sensor 10C and the ambient temperature sensor 10E to determine and / or evaluate and in particular to evaluate with a test criterion. A threshold value for the temperature difference can be provided as a test criterion, for example, the test criterion being considered fulfilled when the temperature difference or a maximum of the temperature difference reaches or exceeds the threshold value during a hygienic flush. In particular, reaching or exceeding it can be an indicator that a heating device is functioning properly, since otherwise - especially in winter or at low ambient temperatures - the temperature of the water in the drinking water system 4th would be identical or very similar to the ambient temperature. In particular, the flushing device 3rd designed to generate, output and / or transmit a message or warning if the test criterion is not met.

However, it is also possible to use the temperature sensor 10C to be used to measure the ambient temperature. The temperature in the flushing device 3rd or the drinking water system 4th namely approaches after a hygienic flush or when the drinking water system is not in use 4th the ambient temperature. In this way, the temperature sensor is also at a sufficient time after a previous hygienic flush 10C can be used to measure the ambient temperature.

According to a further aspect that can also be implemented independently, the present invention also relates to a system 1 with the outlet fitting 2 , the flushing device 3rd and a server 21 . The server 21 is preferably physically of the flushing device 3rd formed separately. The system 1 is preferably designed to take measured values from the sensors 10 or the message, in particular a warning, to the server 21 to be transmitted, in particular automatically and / or wirelessly.

Preferably the server is 21 designed to transmit the measured values or message - in particular wirelessly - to a mobile terminal, in particular in an e-mail, SMS, message from an instant messaging service, a push message or the like.

In a preferred aspect, the server is 21 alternatively or in addition to this formed, the flushing device 3rd to configure, control and / or program. In particular, are with the server 21 So settings of the flushing device 3rd with the server 21 or can be specified and / or changed via the 21. With the server 21 are preferably programs, settings, commands and / or instructions on the flushing device 3rd transferable through the use of the flushing device 3rd hygiene flushings carried out can be controlled, influenced and / or carried out.

The flushing device 3rd so is preferably through the server 21 controllable, configurable and / or programmable.

A programming of the flushing device 3rd through the server 21 can, for example, consist in that (temporary) washing programs or washing schedules, processes, times, or the like of hygiene washing from the server 21 to the flushing device 3rd be transmitted.

Alternatively or additionally, the server 21 is designed to do a firmware update of the flushing device 3rd perform or on the flushing device 3rd to play. In particular, a basic program is stored in a non-volatile memory of the flushing device 3rd and from the time of the corresponding update or transmission from the server 21 to control the flushing device 3rd , in particular to control the opening and / or closing of the valve 9 , used.

A flushing plan and / or settings, which are particularly dependent on one or more of the sensors 10 measured values or data can be adaptable, can preferably be stored in a temporary or volatile memory or by the server 21 be transmitted there. Alternatively or additionally, however, it is also possible to store a flushing plan and / or settings as firmware or as part of firmware in a permanent or non-volatile memory of the flushing device 3rd to file or to transmit there.

The server 21 is preferably designed to actively or directly control or program the flushing device.
The present invention also relates to the methods for the implementation of which the flushing device 3rd or the system 1 - as described above - is formed.

In particular, the present invention therefore relates to a method in which temperature profiles of hygienic flushes are determined and deviations between the temperature profiles are determined.
