Description

Die Erfindung betrifft eine Vorrichtung zum Aufbereiten von Duschwasser für ein Wasserklosett mit Unterdusche, mit einer Leitungsanordnung, die einen Eingang aufweist, der an eine Versorgungsleitung anschliessbar ist und mit einem Ausgang, der an einen Duscharm anschliessbar ist und mit einem Heizelement zum Bereitstellen von warmem Wasser.The invention relates to a device for treating shower water for a water closet with under shower, with a line arrangement having an input which is connectable to a supply line and having an output which is connectable to a shower arm and a heating element for providing warm water ,

Solche Vorrichtungen sind im Stand der Technik seit langem bekannt. Ein Wasserklosett mit einer Unterdusche bzw. einer Warmwasserdusche erübrigt weitgehend die Verwendung von Klosettpapier. In der Praxis haben sich solche Wasserklosetts bereits ausserordentlich bewährt. Das Duschwasser muss auf Körpertemperatur erwärmt werden, damit es vom Duscharm abgegeben werden kann. Hierzu eignet sich insbesondere ein Warmwasserbehälter, wie dies bei der Vorrichtung nach der DE-A-26 30 671 offenbart ist. In diesem Warmwasserbehälter ist zur Erwärmung von Wasser eine Heizvorrichtung angeordnet, die mit einem Thermostaten gekoppelt ist. Mit Hilfe des Thermostaten wird die Wassertemperatur auf der gewünschten Höhe von beispielsweise 40° C gehalten. Die Temperaturhöhe ist verstellbar.Such devices have long been known in the art. A water closet with a sub-shower or a hot shower largely eliminates the use of toilet paper. In practice, such water closets have already proven exceptionally. The shower water must be heated to body temperature so that it can be dispensed by the shower arm. For this purpose, in particular, a hot water tank, as in the device according to the DE-A-26 30 671 is disclosed. In this hot water tank for heating water, a heater is arranged, which is coupled to a thermostat. With the help of the thermostat, the water temperature is maintained at the desired level of, for example, 40 ° C. The temperature level is adjustable.

Durch die WO 2006/079231 ist eine Vorrichtung bekannt geworden, bei welcher zur Aufbereitung von körperwarmem Duschwasser ein Wasserboiler vorgesehen ist. Der Warmwasserboiler besitzt thermostatgesteuerte Heizmittel. Im Boiler wird das Boilerwasser in fest eingestellten Intervallen kurzseitig auf wenigstens 70° C erhitzt und ansonsten permanent auf wenigstens 55° C gehalten. Das kurzzeitige Erhitzen auf wenigstens 70° C ist hier vorgesehen, um im Duschwasser die Keim- und Bakterienzahl zu reduzieren. Zum Erreichen einer körperwarmen Temperatur wird das Duschwasser über ein Mischventil vor der Austrittsdüse der Unterdusche mit Leitungswasser gemischt.By the WO 2006/079231 a device has become known in which a water boiler is provided for the treatment of body-warm shower water. The hot water boiler has thermostat controlled heating means. In the boiler, the boiler water is heated at fixed intervals short side to at least 70 ° C and otherwise permanently maintained at least 55 ° C. The short-term heating up at least 70 ° C is provided here to reduce the germ and bacteria in shower water. To achieve a body temperature, the shower water is mixed via a mixing valve in front of the outlet nozzle of the shower with tap water.

Bei der Aufbereitung des Wassers in einem Warmwasserbehälter kann bei einem Durchfluss von 5.5 1/min und einer Wassertemperatur von 37° C mit einer Duschzeit von etwa 20 Sekunden gerechnet werden. Nach dieser Duschzeit nimmt dann die Wassertemperatur allmählich ab. Eine längere Duschzeit wäre mit einem grösseren Warmwasserbehälter und einem entsprechend höheren Energieverbrauch an sich möglich. Ein grösserer Wasserbehälter ist aber aus Platzgründen nicht möglich oder zumindest nicht erwünscht. Auch ein wesentlich höherer Energieverbrauch sollte vermieden werden.When treating the water in a hot water tank, a showering time of about 20 seconds can be expected at a flow rate of 5.5 1 / min and a water temperature of 37 ° C. After this showering time then the water temperature gradually decreases. A longer shower time would be possible with a larger hot water tank and a correspondingly higher energy consumption per se. However, a larger water tank is not possible or at least undesirable for reasons of space. Even a much higher energy consumption should be avoided.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der genannten Art zu schaffen, die eine längere Duschzeit mit Warmwasser ermöglicht.The invention has for its object to provide a device of the type mentioned, which allows a longer shower time with hot water.

Die Aufgabe ist bei einer gattungsgemässen Vorrichtung dadurch gelöst, dass sie einen Energiespeicher aufweist, mit welchem der Leistungsbereich für die Bereitstellung von Duschwasser erweiterbar ist. In diesem Energiespeicher wird eine bestimmte Menge Energie zwischengespeichert. Dieser Energiespeicher steht während des Duschvorganges als zusätzliche Energiequelle zum Aufbereiten des Duschwassers zur Verfügung. Der Energiespeicher ergänzt beispielsweise einen Durchlauferhitzer. Der Durchlauferhitzer kann während des Duschvorganges dann mit der zur Verfügung stehenden Leistung beispielsweise eines angeschlossenen Stromnetzes gespiesen werden. Das Wasser des Durchlauferhitzers kann dann beispielsweise mit dem Wasser eines Warmwasserbehälters gemischt werden, welcher den Energiespeicher bildet. Dieser Warmwasserbehälter kann auf einer höheren Temperatur von beispielsweise höher als 40° C und niedriger als 90° C gehalten werden. Durch die Kombination eines solchen Durchlauferhitzers und eines Warmwasserspeichers ist beispielsweise eine Duschdauer von einer Minute bei einem Durchfluss von 5.5 1/min und einer Duschtemperatur von 37° C möglich. Anstelle eines Energiespeichers in der Form eines Warmwasserbehälters ist beispielsweise auch ein Energiespeicher in Form eines elektrischen, elektrochemischen oder chemischen Energiespeichers denkbar. Der Energiespeicher könnte beispielsweise ein Akkumulator sein, der an ein elektrisches Netz angeschlossen ist und dessen Leistung während des Duschvorganges erhöht. Nach einem Duschvorgang wird dann der Akkumulator über das Netz wieder geladen. Möglich sind auch Energiespeicher bei denen ein chemischer oder elektrochemischer Vorgang im Bedarfsfall Energie abgibt.The object is achieved in a generic device in that it has an energy storage with which the power range for the provision of shower water is expandable. In this energy storage a certain amount of energy is cached. This energy storage is available during the shower process as an additional source of energy for the treatment of the shower water. The energy storage supplements, for example, a water heater. The water heater can then be fed during the shower process with the available power, for example, a connected power grid. The water of the water heater can then be mixed, for example, with the water of a hot water tank, which forms the energy storage. This hot water tank can be maintained at a higher temperature of, for example, higher than 40 ° C and lower than 90 ° C. By combining such a water heater and a hot water storage, for example, a shower time of one minute at a flow rate of 5.5 1 / min and a shower temperature of 37 ° C is possible. Instead of an energy storage in the form of a hot water tank, for example, an energy storage in the form of an electrical, electrochemical or chemical energy storage is conceivable. The energy storage could for example be an accumulator connected to an electrical network and its performance during the Shower process increased. After a shower process, the accumulator is then recharged via the mains. Also possible are energy storage in which a chemical or electrochemical process in case of need emits energy.

Nach einer Weiterbildung der Erfindung ist vorgesehen, dass der Energiespeicher ein Hochtemperaturspeicher ist, in welchem Wasser mit einer Temperatur bereitstellbar ist, welche höher ist als die Temperatur von körperwarmem Wasser. Die vorgesehene Temperatur des Hochtemperaturspeichers liegt vorzugsweise im Bereich von etwa 40° C bis 90° C. Durch Beimischen von Leitungswasser wird dann die Temperatur auf eine körperverträgliche Temperatur von beispielsweise 37° C gesenkt.According to a development of the invention, it is provided that the energy store is a high-temperature store, in which water can be provided with a temperature which is higher than the temperature of body-warm water. The intended temperature of the high-temperature reservoir is preferably in the range of about 40 ° C to 90 ° C. By admixing tap water, the temperature is then lowered to a body-compatible temperature of, for example, 37 ° C.

Nach einer Weiterbildung der Erfindung ist vorgesehen, dass die Leitungsanordnung einen Wasserkreislauf aufweist, der so an die Unterdusche anschliessbar ist, dass über einen ersten Leitungsast der Unterdusche nicht erwärmtes Wasser und über einen zweiten Leitungsast erwärmtes Wasser zuführbar ist. Das erwärmte Wasser und das nicht erwärmte Wasser können davor oder im Duscharm gemischt werden, so dass schliesslich körperwarmes Duschwasser den Duscharm verlässt. Das nicht erwärmte Wasser kann zudem zum Ausfahren des Duscharms und damit als Antriebsmittel verwendet werden.According to a development of the invention, provision is made for the line arrangement to have a water circuit which can be connected to the subshower such that unheated water and water heated by a second line branch can be supplied via a first line branch of the subshower. The heated water and the unheated water can be mixed in front of it or in the shower arm so that body-warm shower water leaves the shower arm. The unheated water can also be used to extend the shower arm and thus as a drive means.

Nach einer Weiterbildung der Erfindung ist der erste Leitungsast an einen Durchlauferhitzer angeschlossen. Hierbei ist vorzugsweise gemäss einer Weiterbildung der Erfindung im zweiten Leitungsast ein Warmwasserspeicher angeordnet, der über ein Umschaltventil mit dem ersten Leitungsast verbunden ist. Beim Duschvorgang kann dann das im Durchlauferhitzer erwärmte Wasser dem Warmwasserspeicher zugeführt werden, der hierbei gleichzeitig Warmwasser abgibt, das mit Wasser aus dem ersten Leitungsast gemischt wird. Dies ermöglicht einen besonders energiesparenden Betrieb. Ganz allgemein ist eine längere Duschdauer ohne wesentliche Erhöhung der erforderlichen Energie möglich.According to a development of the invention, the first line branch is connected to a water heater. In this case, a hot water tank is preferably arranged according to a development of the invention in the second line branch, which is connected via a switching valve with the first line branch. During the shower process, the water heated in the water heater can then be supplied to the hot water tank, which at the same time emits hot water, which is mixed with water from the first pipe branch. This enables a particularly energy-saving operation. In general, a longer shower time without significant increase in the required energy is possible.

Die Erfindung betrifft zudem ein Verfahren zum Betrieb einer erfindungsgemässen Vorrichtung. Bei diesem Verfahren ist insbesondere vorgesehen, dass die Vorrichtung im Ruhezustand im Schlafzustand ist und dass sie im Hinblick auf einen Benutzer überwacht wird. Wird ein Benutzer detektiert, so wird der Schlafzustand aufgehoben und vor der Abgabe von Duschwasser kann der Energiespeicher geladen werden. Im Fall eines Warmwasserbehälters wird in diesem das Duschwasser erwärmt bzw. auf eine höhere Temperatur gebracht. Die Energiezufuhr kann hier beispielsweise über ein elektrisches Netz erfolgen. Das Heizsystem kann hierbei unter Volllast arbeiten. Während des Duschvorganges findet hier vorzugsweise ein geregeltes Mischen von Speicherwasser aus dem Warmwasserbehälter und Wasser aus dem Durchlauferhitzer statt. Das Heizsystem kann hierbei weiterhin unter Volllast arbeiten. Denkbar ist hier auch ein Beimischen von Wasser, das vorher nicht erwärmt wurde. Ist der Energiespeicher beispielsweise ein Akku, so wird er während des Duschvorganges entladen, so dass die Leistung des Netzes durch die Leistung des Akkus unterstützt wird. In diesem Fall wird das Wasser beispielsweise ausschliesslich im Durchlauferhitzer erwärmt. Verglichen mit dem Stand der Technik kann hierbei somit bei gleicher Netzleistung eine längere Duschdauer erreicht werden, da Energie aus dem Akku bereitgestellt wird.The invention also relates to a method for operating a device according to the invention. In this method, it is provided in particular that the device is in the sleep state at rest and that it is monitored with regard to a user. If a user is detected, the sleep state is canceled and before Dispensing shower water, the energy storage can be charged. In the case of a hot water tank in this the shower water is heated or brought to a higher temperature. The power supply can be done here for example via an electrical network. The heating system can work under full load. During the showering process, a controlled mixing of storage water from the hot water tank and water from the instantaneous water heater preferably takes place here. The heating system can continue to work under full load. It is also conceivable here an admixing of water that was not previously heated. For example, if the energy storage device is a rechargeable battery, it will be discharged during the showering process so that the power of the network is supported by the power of the rechargeable battery. In this case, the water is heated, for example, exclusively in a water heater. Compared to the state of the art, a longer shower time can thus be achieved with the same network performance, since energy is supplied from the battery.

Nach dem Duschvorgang kann der Energiespeicher wieder geladen werden. Im Fall eines Warmwasserspeichers kann in diesem die Wassertemperatur erhöht und mittels eines Thermostaten auf einer bestimmten Temperatur gehalten werden. Im Fall eines Akkumulators wird dieser wieder über das Netz geladen. Denkbar ist auch eine Ausführung mit mehreren Energiespeichern, beispielsweise einem Warmwasserspeicher und einem Akkumulator.After the shower process, the energy storage can be reloaded. In the case of a hot water tank, the water temperature can be increased in this and kept at a certain temperature by means of a thermostat. In the case of a rechargeable battery, it will be recharged via the mains. Also conceivable is a design with multiple energy storage, such as a hot water tank and an accumulator.

Die in der einzigen Figur gezeigte erfindungsgemässe Vorrichtung 1 besitzt eine Leitungsanordnung 2 die einen Eingang 3 aufweist. Dieser Eingang 3 ist an eine hier nicht gezeigte Versorgungsleitung, beispielsweise eine Wasserdruckleitung anschliessbar. Der Anschluss kann beispielsweise über eine hier nicht gezeigte Schraubverbindung oder dergleichen erfolgen. Die Strömungsrichtung, in welcher der Leitungsanordnung Wasser zuführbar ist, ist mit dem Pfeil 18 angedeutet. Nach dem Einlass ist ein Filter 9 angeordnet, in dem das zugeführte Wasser gefiltert ist. Der Filter 9 kann ein an sich bekannter Wasserfilter sein. Nach dem Filter 9 ist in der Leitungsanordnung 2 ein Ventil 10, insbesondere ein Absperrventil angeordnet. Mit diesem kann die Zufuhr von Wasser zu den weiter unten erwähnten Elementen unterbrochen werden.The inventive device 1 shown in the single figure has a line arrangement 2 which has an input 3. This input 3 can be connected to a supply line, not shown here, for example, a water pressure line. The connection can be made for example via a screw connection, not shown here or the like. The flow direction, in which the conduit arrangement water can be fed, is indicated by the arrow 18. After the inlet, a filter 9 is arranged, in which the supplied water is filtered. The filter 9 may be a per se known water filter. After the filter 9, a valve 10, in particular a shut-off valve is arranged in the line arrangement 2. With this, the supply of water to the elements mentioned below can be interrupted.

Die Leitungsanordnung 2 bildet nach dem Ventil 10 einen Wasserkreislauf. Dieser besitzt einen ersten Leitungsast 2a, in dem eine Pumpe 11 angeordnet ist, die eine an sich bekannte Wasserpumpe ist und mit der Leitungswasser einem Duscharm 5 einer hier weiter nicht gezeigten Unterdusche zuführbar ist. Zwischen der Pumpe 11 und dem Duscharm 5 sind wie gezeigt ein Regler 14 sowie ein weiteres Ventil 15 angeordnet. Das Ventil 15 ist vorzugsweise ein Regelventil, mit dem die Zufuhr von Wasser zum Duscharm 5 geregelt werden kann.The line assembly 2 forms after the valve 10 a water cycle. This has a first line branch 2a, in which a pump 11 is arranged, which is a per se known water pump and with the tap water a shower arm 5 of a sub-shower not shown here can be fed. As shown, a regulator 14 and a further valve 15 are arranged between the pump 11 and the shower arm 5. The valve 15 is preferably a control valve with which the supply of water to the shower arm 5 can be controlled.

Der genannte Wasserkreislauf besitzt zudem einen zweiten Leitungsast 2b, der über eine Verbindungsleitung 19 nach der Pumpe 11 mit dem ersten Leitungsast 2a verbunden ist. Diese Verbindungsleitung 19 führt zu einem Heizelement 6, das beispielsweise und vorzugsweise ein Durchlauferhitzer ist. Der Durchlauferhitzer ist hier an eine elektrische Versorgungsleitung 13 angeschlossen. Diese Leitung 13 ist beispielsweise ein elektrisches Netz, oder eine andere geeignete Energiequelle. Über eine weitere Verbindungsleitung 2d ist das Heizelement 6 mit einem Energiespeicher 7 verbunden. Das im Heizelement 6 erwärmte Wasser kann somit über diese Verbindungsleitung 2d dem Energiespeicher 7 zugeführt werden.Said water circuit also has a second line branch 2 b, which is connected via a connecting line 19 after the pump 11 to the first line branch 2 a. This connecting line 19 leads to a heating element 6, which is for example and preferably a water heater. The water heater is connected here to an electrical supply line 13. This line 13 is, for example, an electrical network, or another suitable source of energy. Via a further connecting line 2d, the heating element 6 is connected to an energy store 7. The heated water in the heating element 6 can thus be supplied to the energy storage 7 via this connection line 2d.

Der Energiespeicher 7 ist hier beispielsweise ein Warmwasserspeicher bzw. ein Boiler, der hier ebenfalls an die Versorgungsleitung 13 angeschlossen ist und in dem beispielsweise über ein elektrisches Heizelement Wasser erwärmt und gespeichert werden kann. Der Energiespeicher 7 ist vorzugsweise thermisch isoliert, so dass der Energieverlust vermindert werden kann. Im Energiespeicher 7 kann das Wasser beispielsweise auf eine Temperatur zwischen etwa 40 bis 90° C erwärmt und gehalten werden. Über einen hier nicht gezeigten Temperaturregler kann eine vorbestimmte Temperatur gehalten werden. Geeignete Steuermittel hierzu sind dem Fachmann an sich bekannt.The energy storage 7 is here, for example, a hot water tank or a boiler, which is also connected here to the supply line 13 and can be heated and stored in the example, via an electric heating water. The energy store 7 is preferably thermally insulated, so that the energy loss can be reduced. In the energy storage 7, the water can be heated and maintained, for example, to a temperature between about 40 to 90 ° C. About a temperature controller, not shown here, a predetermined temperature can be maintained. Suitable control means for this purpose are known per se to those skilled in the art.

Der Energiespeicher 7 ist mit einem Umschaltventil 12, das beispielsweise ein Dreiwegeventil ist, verbunden. Dieses Ventil 12 ist hier über eine weitere Verbindungsleitung 2c mit dem Eingang 3 verbunden. Über die Verbindungsleitung 2c und das Umschaltventil kann dem Energiespeicher 7 direkt Wasser zugeführt werden. Somit kann dem Energiespeicher 7 einerseits über die Verbindungsleitung 2d erwärmtes Wasser und über das Umschaltventil 12 nicht erwärmtes Wasser bzw. Wasser aus dem Eingang 3 zugeführt werden. Das Umschaltventil 12 ist zudem über den zweiten Leitungsast 2b mit dem Duscharm 5 verbunden. Zwischen dem Umschaltventil 12 und dem Duscharm 5 sind ein Regler 17 und ein Ventil 16 angeordnet. Dem Duscharm 5 kann damit über den zweiten Leitungsast 2b geregelt warmes Wasser zugeführt werden. Dieses kann mit dem Wasser aus dem ersten Leitungsast 2a gemischt werden. Sensoren zum Ermitteln der entsprechenden Wassertemperaturen sind vorgesehen, hier jedoch nicht gezeigt. Ebenfalls nicht gezeigt ist eine geeignete Steuervorrichtung, welche die genannten Ventile sowie das Heizelement 6 und den Energiespeicher 7 regeln. Ebenfalls nicht gezeigt und an sich bekannt sind Betätigungsmittel, mit denen der Duschvorgang ausgelöst werden kann. Die Auslösung kann beispielsweise über eine Taste oder berührungslos erfolgen.The energy store 7 is connected to a switching valve 12, which is for example a three-way valve. This valve 12 is connected here via a further connecting line 2c to the input 3. About the connecting line 2c and the switching valve can be supplied to the energy storage 7 directly water. Thus, the energy storage 7 on the one hand via the connecting line 2 d heated water and the switching valve 12 unheated water or water from the input 3 are supplied. The switching valve 12 is also connected via the second line branch 2 b with the shower arm 5. Between the switching valve 12 and the shower arm 5, a regulator 17 and a valve 16 are arranged. The shower arm 5 can thus be supplied regulated via the second line branch 2b warm water. This can be mixed with the water from the first line branch 2a. Sensors for determining the corresponding water temperatures are provided, but not shown here. Also not shown is a suitable control device which regulate said valves and the heating element 6 and the energy storage 7. Also not shown and known per se are actuating means with which the showering process can be triggered. The triggering can be done for example via a button or contactless.

Nachfolgend wird das erfindungsgemässe Verfahren näher erläutert.The method according to the invention will be explained in more detail below.

Im Ruhezustand ist der Energiespeicher 7 mit Wasser gefüllt. Das Ventil 10 ist geschlossen und die Vorrichtung 1 in einem Schlafinodus. Im Energiespeicher 7 wird eine bestimmte Temperatur, beispielsweise 40° C oder weniger gehalten. Während des Ruhezustandes wird beispielsweise über einen Sensor in einem Klosettsitz eine eventuelle Benutzung überwacht. Wird ein Benutzer festgestellt, so wird das Wasser im Energiespeicher 7 erwärmt, so dass die Temperatur schliesslich im Bereich zwischen etwa 40° C und 90° C liegt. Der Energiespeicher 7 wird somit geladen. Das Laden erfolgt hier vorzugsweise unter Volllast. Der Energiespeicher 7 wird in vergleichsweise kurzer Zeit geladen bzw. die Temperatur auf den gewünschten Wert erhöht. Gleichzeitig oder alternativ kann der Energiespeicher 8 geladen werden. Ist dieser ein Akkumulator, so wird dieser entsprechend über die Versorgungsleitungen 13 geladen.At rest, the energy storage 7 is filled with water. The valve 10 is closed and the device 1 in a sleep mode. In the energy storage 7, a certain temperature, for example, 40 ° C or less is maintained. During the idle state, a possible use is monitored, for example via a sensor in a toilet seat. If a user is detected, the water in the energy storage 7 is heated, so that the temperature is finally in the range between about 40 ° C and 90 ° C. The energy store 7 is thus charged. The loading is done here preferably under full load. The energy store 7 is charged in a comparatively short time or increases the temperature to the desired value. At the same time or alternatively, the energy store 8 can be charged. If this is an accumulator, it is charged accordingly via the supply lines 13.

Wird vom Benutzer der Duschvorgang ausgelöst, so wird das Umschaltventil 12 geschaltet und die Pumpe 11 aktiviert. Ebenfalls wird das Heizelement 6 eingeschaltet. Im Heizelement wird Wasser erhitzt und dieses wird dem Energiespeicher 7 zugeführt. Das Wasser aus dem Heizelement 6 wird hierbei mit dem Wasser des Energiespeichers 7 gemischt. Um die gewünschte Temperatur für den Duschvorgang zu erreichen, kann über das Umschaltventil 12 vergleichsweise kaltes Wasser über die Verbindungsleitung 2c zugeführt werden. Über den zweiten Leitungsast 2b gelangt nun Wasser zum Duscharm 5. Das Ventil 6 ist entsprechend geöffnet und geregelt. Dem Duscharm 5 kann gleichzeitig über den ersten Leitungsast 2 auch vergleichsweise kaltes Wasser zugeführt werden und beigemischt werden. Das Wasser aus dem zweiten Leitungsast 2a kann aber auch verwendet werden, um den Duscharm 5 in die Bereitschaftsstellung zu bewegen. Dies wird ebenfalls über das Ventil 15 geregelt. Das Wasser aus dem zweiten Leitungsast 2a dient somit in diesem Fall als Antriebsmittel um den Duscharm 5 zu verfahren. Hydraulisch bewegbare Duscharme 5 sind dem Fachmann an sich bekannt. Während des Duschvorganges arbeitet das Heizsystem vorzugsweise weiterhin in Volllast. Der Duschvorgang wird vom Benutzer oder selbsttätig unterbrochen. Anschliessend wird der Energiespeicher 7 wieder geladen und auf eine bestimmte Temperatur geregelt. Alternativ oder gleichzeitig kann der Energiespeicher 8 ebenfalls geladen werden. Die Vorrichtung 1 wird schliesslich wieder in den Schlafmodus versetzt. Die Vorrichtung 1 ist nun wieder für einen weiteren Duschvorgang bereit.If the user initiates the shower process, then the switching valve 12 is switched and the pump 11 is activated. Also, the heating element 6 is turned on. in the Heating element is heated water and this is supplied to the energy storage 7. The water from the heating element 6 is in this case mixed with the water of the energy store 7. In order to achieve the desired temperature for the showering process, comparatively cold water can be supplied via the connecting line 2c via the switching valve 12. Water now reaches the shower arm 5 via the second line branch 2b. The valve 6 is opened and regulated accordingly. The shower arm 5 can also be supplied via the first line branch 2 and comparatively cold water and mixed. However, the water from the second conduit branch 2a can also be used to move the shower arm 5 into the ready position. This is also regulated via the valve 15. The water from the second line branch 2 a thus serves in this case as a drive means to move the shower arm 5. Hydraulically movable Duscharme 5 are known in the art. During the showering process, the heating system preferably continues to operate at full load. The showering process is interrupted by the user or automatically. Subsequently, the energy storage 7 is recharged and regulated to a certain temperature. Alternatively or simultaneously, the energy store 8 can also be charged. The device 1 is finally put back into sleep mode. The device 1 is now ready for another showering process.
