Definitions

  • the invention relates to a household appliance for dispensing liquid according to the preamble of claim 1.
  • the WO 2014/190994 A1 describes a water dispensing system with a faucet and a mixer tap.
  • the WO 94/20784 A1 describes a faucet with a line for chilled water and a line for hot water, which are led separately from one another to an outlet of the faucet.
  • a processing system for liquid which is used in a household is known from the prior art.
  • sanitary fittings are known as dispensing units for the liquid in a further specification. So is from the DE 10 2013 002 857 A1 such a sanitary fitting for tapping water is known.
  • a boiler is also associated with this household appliance. With this, hot water can be made available which is significantly warmer in temperature than usually via a hot water pipe which is connected to the external water network and which can be dispensed via this sanitary fitting or the faucet.
  • the device there has a water outlet line to which a negative pressure can be applied when a valve element is closed.
  • the water located in the water outlet line is at least partially sucked into a water reservoir counter to the outflow direction. Due to the curved geometry there, in particular a gooseneck geometry, of the sanitary fitting, an interruption is generated there during this back suction process via a line breaker at the maximum of this gooseneck bend, so that that part of the residual water in the water outlet line that is up to an outlet opening in this sanitary fitting is over this discharge opening is explicitly drained and the part that is upstream of this line breaker is located, is sucked back into the water reservoir, namely the boiler.
  • both the targeted supply of hot water to the dispensing opening of the sanitary fitting and the removal of the remaining water after a dispensing process are carried out via this single water outlet line.
  • the return of this water that is no longer required and no longer dispensed from the line into the boiler has disadvantages in that, on the one hand, this already cooled water has to be warmed up again or the water in the boiler cools down. On the other hand, such a return requires a complex process, which in particular requires this specific line breaker at a specific position.
  • the device has a fitting body as the output unit, which represents a sanitary fitting and thus a water tap.
  • the fitting body is connected to an external water network.
  • This connection device has a cold water pipe and a hot water pipe.
  • a mixing valve is arranged between an output opening of the fitting body and these two feed lines in order to enable the water from the cold water feed line and the hot water feed line to be mixed, if necessary.
  • the device has a hot water system which has a boiler.
  • the boiler is connected to the fitting body and in particular to the output unit there via a separate line unit in which a valve is also arranged.
  • the line unit is completely separated and led separately to this dispensing opening and is therefore not connected to it Line that leads from the mixing valve to the discharge opening of the fitting body.
  • the object of the present invention is to create a household appliance for dispensing liquids or a liquid treatment system for the household in which the discharge of residual mixed liquid is improved.
  • the invention relates to a household appliance for dispensing liquid.
  • the household appliance has a dispensing unit for dispensing the liquid.
  • This output unit is a sanitary fitting.
  • the household appliance also has a connection device for connecting the household appliance to an external water network.
  • the household appliance also has a water temperature control system that is separate from the connection device. With the water temperature control system, water supplied to the water temperature control system from the external water network can be individually temperature controlled.
  • the water temperature control system has a line unit with which the water temperature control system is connected to the output unit.
  • the water temperature control system has a line device separate from this line unit, with which the water of the device-external water network, in particular without being routed via the water temperature control system, can be routed directly from the connection device to the output unit.
  • the water temperature control system opens out on a line of the output unit, which is arranged to conduct a temperature-controlled water from the water temperature control system having liquid.
  • a drain line separate from this line branches off from the line for draining the remaining liquid remaining in the line after the liquid has been dispensed.
  • the line is a mixed line.
  • the line at which the discharge line opens is the mixed line.
  • a mixed liquid can also be conducted therein, in particular can be conducted directly to the dispensing opening of the dispensing unit.
  • the mixed liquid can consist of at least two separate Liquids, in particular from different water temperature control systems of the household appliance, can be mixed. The remaining liquid that can be drained off via the drain line is then a remaining mixed liquid.
  • the water temperature control system has the hot water system which is separate from the line device and with which a water supplied from the water network external to the device can be heated.
  • the water temperature control system also has a cooled water system that is separate from the hot water system and the line device, with which water supplied from the water network external to the device can be cooled.
  • a chilled water system is thus understood to be a system with which the water supplied from a water network external to the device can be actively cooled and, in this regard, to a lower temperature.
  • Such an even more separate system can also increase the variability of the household appliance with regard to the most varied of temperature control options for the liquids.
  • the general flexibility for the generation of mixed liquids both in terms of type and temperature control is improved as a result.
  • this cooled water system is also designed separately from the hot water system and separate from this line device, which is directly connected to the external water network, the individual temperature control processes in the different systems can take place particularly advantageously.
  • the individual tempering of the liquids can be carried out very efficiently and precisely, so that a possible subsequent mixing of liquids from these systems can then also take place in a very needs-based manner.
  • the hot water system and the cooled water system open out to the mixed pipe at the same mouth.
  • a mixing point is thus created on the household appliance, in which hot water from the hot water system and cooled water from the cooled water system can be mixed and can therefore be introduced directly into the mixing line in this regard.
  • a mixed liquid which can be mixed from the hot water from the hot water system and the cooling water from the cooled water system, can thus then be fed via the mixing line.
  • An additional, second possibility is thus created in the household appliance for outputting mixed liquid, which can be mixed from the systems mentioned, via this specific mixed line.
  • connection device can also output a separate mixed liquid, which can advantageously be mixed from the water that can be mixed from a hot water feed line of the line device and from cold water that can be mixed from a cold water feed line of the line device.
  • the connection device is connected to the output unit with a specific connecting line, this connecting line being a separate line to the above-mentioned line, namely the mixed line.
  • the mouth at which the drain line opens into the mixed line is the same as the mouth at which the hot water system and the cooled water system open into the mixed line.
  • Such a complete common mixing point enables simplified wiring.
  • a common valve is also arranged at such a circumferential common mixing point, so that the number of valves present can then also be reduced here.
  • a valve is arranged in the mixing line between the mouth and an output opening of the output unit. Such a configuration enables the hot water to be supplied to this mixing line as required in a particularly advantageous manner. Depending on the operating position of this valve, this hot water can be metered very precisely.
  • This valve which can also be referred to as a flush valve, thus enables the remaining liquid to be drained from the mixing line in a particularly needs-based manner.
  • the drain line is not in direct contact with the dispensing opening of the dispensing unit.
  • the discharge line opens into the line at a distance to the dispensing opening of the dispensing unit.
  • the discharge opening of the discharge line is also separated and has no contact or connection with the dispensing opening of the dispensing unit.
  • This basin can be, for example, a sink or another tub area.
  • the output unit of the household appliance is a sanitary fitting, which can also be referred to as a faucet.
  • a functionally specific unit which is basically designed to output water from a connected, device-external water network, is functionally expanded by such a configuration.
  • the discharge line opens into a residual reservoir separate from the dispensing unit.
  • This is advantageous in that this remaining liquid that is no longer required can be collected and no longer reaches a unit of the household appliance in which liquid that is subsequently still required or intended for dispensing is contained. This also makes it possible for the liquid to be able to collect for a longer period in this separate residual reservoir.
  • This separate residual reservoir can advantageously be accessible to a user in order to be able to remove it. This can be advantageous for disposal measures for the remaining liquid collected therein. This is also advantageous for cleaning purposes of this residual reservoir.
  • the remaining reservoir is connected to a waste water network external to the device.
  • this remaining residual liquid which is also no longer required and in particular is to be disposed of, can be routed directly and specifically into a correspondingly provided waste water network, in particular a domestic waste water network.
  • this connection of the residual reservoir to the waste water network external to the device takes place in such a way that no line path in this regard leads between the residual reservoir and the external waste water network via an output opening of the output unit.
  • the discharge line does not open into an output opening of the output unit which is at least designed for outputting the liquid.
  • the chilled water system is preferably also connected to the line device. It is then also possible for water coming from the domestic water network to be conducted via the line device directly to the dispensing unit, in particular to the dispensing opening of the dispensing unit. It can also be provided that in this regard water coming from the external water network can then be diverted from the line device at least partially and in particular as a function of demand into the chilled water system. These explanations then also apply accordingly to the hot water system. This can also be connected in particular to a cold water supply line of the connection device in order to branch off water flowing from the external water network via the cold water supply line and feed it into the hot water system.
  • the hot water and the cooled water are mixed only at the dispensing opening or directly after dispensing from the dispensing opening.
  • a hot water preparation container in particular a boiler, is preferably part of the hot water system.
  • the drain line viewed in the vertical direction of the household appliance, is arranged completely and in particular without a minimum in the line, below the mouth at which the water temperature control system, in particular the hot water system and the cooled water system, open onto the line.
  • This is a particularly advantageous embodiment, because it allows the remaining liquid to be drained off solely on the basis of gravity. No pump or other conveying unit is required in order to be able to drain this residual liquid via the drain line.
  • the household appliance has a display unit on which information on a current or future fresh water filling of the chilled water system is displayed. As a result, a user of the household appliance is informed at all times about the circumstances of the fresh water requirement.
  • a valve is advantageously arranged in the discharge line. Such a drainage valve is advantageous in that no undesired dripping or leakage of liquid would occur from this drainage line.
  • this valve is also arranged in the drain line directly at the mouth at which the drain line opens into the mixed line.
  • the valves advantageously present in the mixing line and the discharge line can thus be combined as one valve.
  • the household appliance has a control unit with which at least one valve can be adjusted in its operating position.
  • control unit Since the control unit is designed to flush at least one line unit immediately before a liquid is dispensed by the dispensing unit by activating at least one valve, liquid at the correct temperature is available at the dispensing unit at the beginning of the liquid dispensing. This avoids, for example, that when hot water is drawn off, the water that is present in the lines downstream of the boiler and that has cooled down over time is dispensed first.
  • the control unit opens, for example, the water inlet valve for the boiler and the drainage valve of the drain line until the line unit leading from the boiler to the mouth of the drain line and mixing line is flushed.
  • the flushing time is designed to be as short as possible and is, for example, in the range from 0.5 to 2 seconds.
  • the flushing time can also be carried out by evaluating a temperature sensor.
  • the control unit controls the valves in such a way that the liquid is dispensed exclusively via the dispensing unit. Provision can be made for the lines downstream of a hot water system and a cooled water system to be flushed individually or at the same time as required.
  • the line device has a cold water line and a separate hot water line, the water temperature control system, in particular the hot water system and / or the cooled water system, being connected inside the device to the cold water line for supplying water to the water temperature control system.
  • the water temperature control system in particular the cooled water system, is connected to a carbonation unit of the household appliance and / or to a medium addition unit of the household appliance.
  • the carbonation unit can supply carbon dioxide to the cooled liquid in the cooled water system, so that a carbonated liquid medium can also be generated and dispensed.
  • the medium addition unit can be used to add individual flavor notes, in which case, for example, a liquid or a gel or a powder can be added as an additive as a medium. Other additives are also possible.
  • the addition of minerals or sweeteners or the like can also be provided in the media addition unit.
  • the hot water system is designed in such a way that the water present therein can be heated to temperatures of over 90 °.
  • the chilled water system is designed in such a way that the water contained therein can also be cooled to temperatures below 10 °.
  • valves mentioned are preferably designed as electrical valves which can be controlled in particular via a control unit which has already been explained and presented.
  • the valve which is preferably present in the drain line is in an open position in a normal operating state, so that the remaining liquid to be dispensed can always run off without restriction in such a dispensing process. This would enable this remaining liquid to be drained via the drain line even in the event of a power failure.
  • this valve in the discharge line is closed. Then, especially in the case of designs in which the discharge line specifically opens into the mixing line, an at least partially undesired discharge of the liquid via the discharge line is prevented.
  • a further advantageous embodiment is achieved in that the cooled water system can also be flushed accordingly and then this liquid, which circulates in the cooled water system during this flushing process, can be drained off via the drain line.
  • the cooled water system is fluidically connected to the discharge line, in particular that it joins the mixed line at a common opening point or a common opening.
  • Such a flushing option can avoid the formation of germs and biofilms in the cooled water system and a very advantageous discharge of the liquid after the flushing process can take place externally to the output unit from the cooled water system.
  • the household appliance has a pump through which the flushing medium is conveyed in the cooled water system.
  • pressure can also be supplied from the external water network.
  • the valve present in the mixing line is closed during such a flushing process, so that no flushing liquid of this type is dispensed via the dispensing opening of the dispensing unit.
  • the rinsing and also the delivery of the rinsing liquid are carried out virtually unnoticed by a user, since no such rinsing liquid emerges via the dispensing opening of the dispensing unit.
  • the mixing line can be automatically filled and emptied after a liquid has been drawn off.
  • such a configuration can also allow the mixing line to be rinsed through, so that especially when a mixed liquid, in particular with additives such as those mentioned above, has been dispensed, such additives are prevented from remaining in the mixing line. In this way, too, alienation of liquids to be subsequently dispensed by the additives still present in the mixing line can be prevented and germ growth or the formation of biofilms in the mixing line due to these remaining additives can be prevented.
  • the household appliance can also be designed in such a way that it has a carbonation unit and / or a medium addition unit even if it does not have a chilled water system.
  • the household appliance in particular in the embodiment with the output unit as a sanitary fitting, is a household appliance that is separate from another household appliance, for example a household refrigerator or a fully automatic coffee machine.
  • the household appliance explained above is therefore not part of a household refrigerator or a fully automatic coffee machine in these designs.
  • the household appliance explained can also be constructed in a relatively compact and space-saving manner and can be installed at locations in the household where such appliances such as household refrigerators or fully automatic coffee machines cannot be installed.
  • this embodiment of the household appliance can then also be arranged in the area of a kitchen unit with a sink or some other collecting basin.

Die WO 2014/190994 A1 beschreibt ein Wasserausgabesystem mit einem Wasserhahn und einer Mischbatterie.the WO 2014/190994 A1 describes a water dispensing system with a faucet and a mixer tap.

Die WO 94/20784 A1 beschreibt einen Wasserhahn mit einer Leitung für gekühltes Wasser und einer Leitung für heißes Wasser, welche separat voneinander zu einem Auslass des Wasserhahns geführt sind.the WO 94/20784 A1 describes a faucet with a line for chilled water and a line for hot water, which are led separately from one another to an outlet of the faucet.

Ein Aufbereitungssystem für Flüssigkeit, welches in einem Haushalt eingesetzt ist, ist aus dem Stand der Technik bekannt. In dem Zusammenhang sind in weiterer Spezifikation Sanitärarmaturen als Ausgabeeinheiten für die Flüssigkeit bekannt. So ist aus der DE 10 2013 002 857 A1 eine derartige Sanitärarmatur zum Zapfen von Wasser bekannt. Dort ist in einer weiteren Ausgestaltung auch bekannt, dass zu diesem Haushaltsgerät neben der Sanitärarmatur auch ein Boiler zugehörig ist. Mit diesem kann Heißwasser zur Verfügung gestellt werden, welches temperaturmäßig deutlich wärmer ist als üblicherweise über eine Warmwasserleitung, welche mit dem geräteexternen Wassernetz verbunden ist, und welches über diese Sanitärarmatur beziehungsweise den Wasserhahn ausgegeben werden kann. Das dortige Gerät weist eine Wasserauslaufleitung auf, welche mit dem Schließen eines Ventilelements mit einem Unterdruck beaufschlagbar ist. Mittels dieses Unterdrucks wird das in der Wasserauslaufleitung befindliche Wasser zumindest teilweise entgegen der Ausströmrichtung in einen Wasserspeicher gesaugt. Aufgrund der dortigen gekrümmten Geometrie, insbesondere einer Schwanenhalsgeometrie, der Sanitärarmatur wird dort bei diesem Rücksaugvorgang über einen Leitungsunterbrecher an dem Maximum dieser Schwanenhalskrümmung eine Unterbrechung erzeugt, sodass derjenige Teil des Restwassers in der Wasserauslaufleitung, der sich bis zu einer Ausgabeöffnung in dieser Sanitärarmatur befindet, über diese Ausgabeöffnung explizit abgelassen wird und derjenige Teil, der sich stromaufwärts dieses Leitungsunterbrechers befindet, wird in den Wasserspeicher, nämlich den Boiler, zurückgesaugt. Es wird also über eine einzige Leitung, nämlich die Wasserauslaufleitung, sowohl das gezielte Zuführen des heißen Wassers bis zur Ausgabeöffnung der Sanitärarmatur hin durchgeführt als auch über diese einzige Wasserauslaufleitung dann das Abführen des darin verbliebenen restlichen Wassers nach einem Ausgabeprozess durchgeführt. Die Rückführung dieses nicht mehr benötigten und nicht mehr ausgegebenen Wassers von der Leitung in den Boiler weist Nachteile dahingehend auf, dass einerseits dieses dann bereits abgekühlte Wasser wieder aufgewärmt werden muss beziehungsweise das in dem Boiler befindliche Wasser abkühlt. Andererseits ist durch eine derartige Rückführung ein aufwendiger Prozess erforderlich, der insbesondere diesen spezifischen Leitungsunterbrecher an spezifischer Position benötigt. Ein weiterer wesentlicher Nachteil ist jedoch darin zu sehen, dass auch noch ein gewisser Anteil dieses restlichen Wassers über die Ausgabeöffnung der Sanitärarmatur ausläuft, sodass hier für einen Nutzer die Situation entstehen kann, dass ihm relativ heißes Wasser über die Hände laufen kann. Andererseits kann auch durch beispielsweise dieses Auströpfeln oder Auslaufen in einem kleinen Rinnsal der Eindruck einer nicht mehr voll funktionsfähigen Sanitärarmatur bei einem Nutzer entstehen, da nach dem Beenden eines Ausgabeprozesses ein derartiges Auslaufen erfolgt, was auch einen undichten und qualitativ nachteiligen Eindruck erweckt.A processing system for liquid which is used in a household is known from the prior art. In this context, sanitary fittings are known as dispensing units for the liquid in a further specification. So is from the DE 10 2013 002 857 A1 such a sanitary fitting for tapping water is known. In a further embodiment, it is also known there that, in addition to the sanitary fitting, a boiler is also associated with this household appliance. With this, hot water can be made available which is significantly warmer in temperature than usually via a hot water pipe which is connected to the external water network and which can be dispensed via this sanitary fitting or the faucet. The device there has a water outlet line to which a negative pressure can be applied when a valve element is closed. By means of this negative pressure, the water located in the water outlet line is at least partially sucked into a water reservoir counter to the outflow direction. Due to the curved geometry there, in particular a gooseneck geometry, of the sanitary fitting, an interruption is generated there during this back suction process via a line breaker at the maximum of this gooseneck bend, so that that part of the residual water in the water outlet line that is up to an outlet opening in this sanitary fitting is over this discharge opening is explicitly drained and the part that is upstream of this line breaker is located, is sucked back into the water reservoir, namely the boiler. Thus, via a single line, namely the water outlet line, both the targeted supply of hot water to the dispensing opening of the sanitary fitting and the removal of the remaining water after a dispensing process are carried out via this single water outlet line. The return of this water that is no longer required and no longer dispensed from the line into the boiler has disadvantages in that, on the one hand, this already cooled water has to be warmed up again or the water in the boiler cools down. On the other hand, such a return requires a complex process, which in particular requires this specific line breaker at a specific position. Another significant disadvantage, however, is the fact that a certain proportion of this remaining water also runs out through the dispensing opening of the sanitary fitting, so that the situation here can arise for a user that relatively hot water can run over his hands. On the other hand, this dripping or leakage in a small trickle can give a user the impression of a no longer fully functional sanitary fitting, since after the end of a dispensing process such leakage occurs, which also creates a leaky and qualitatively disadvantageous impression.

Darüber hinaus ist aus der DE 10 2008 006 255 A1 eine Vorrichtung zur Abgabe von Wasser bekannt. Auch dort weist die Vorrichtung als Ausgabeeinheit einen Armaturenkörper auf, der eine Sanitärarmatur und somit einen Wasserhahn darstellt. Bei der dortigen Ausführung ist der Armaturenkörper mit einem geräteexternen Wassernetz verbunden. Diese Anschlussvorrichtung weist eine Kaltwasserleitung und eine Warmwasserleitung auf. Zwischen einer Ausgabeöffnung des Armaturenkörpers und diesen beiden Zuleitungen ist ein Mischventil angeordnet, um gegebenenfalls auch ein Mischen des Wassers aus der Kaltwasserzuleitung und der Warmwasserzuleitung zu ermöglichen.In addition, from the DE 10 2008 006 255 A1 a device for dispensing water is known. There, too, the device has a fitting body as the output unit, which represents a sanitary fitting and thus a water tap. In the version there, the fitting body is connected to an external water network. This connection device has a cold water pipe and a hot water pipe. A mixing valve is arranged between an output opening of the fitting body and these two feed lines in order to enable the water from the cold water feed line and the hot water feed line to be mixed, if necessary.

Separat dazu weist die Vorrichtung in einem Ausführungsbeispiel ein Heißwassersystem auf, welches einen Boiler aufweist. Der Boiler ist über eine separate Leitungseinheit, in der ebenfalls ein Ventil angeordnet ist, mit dem Armaturenkörper und insbesondere der dortigen Ausgabeeinheit verbunden. Die Leitungseinheit ist völlig getrennt und separat zu dieser Ausgabeöffnung geführt und steht somit in keiner Verbindung mit derjenigen Leitung, die von dem Mischventil zur Ausgabeöffnung des Armaturenkörpers führt. Die Funktionalität dieser Vorrichtung bezüglich der Erzeugung unterschiedlich gemischter und/oder unterschiedlich temperierter Flüssigkeiten, die ausgegeben werden können, ist dadurch eingeschränkt.Separately from this, in one exemplary embodiment the device has a hot water system which has a boiler. The boiler is connected to the fitting body and in particular to the output unit there via a separate line unit in which a valve is also arranged. The line unit is completely separated and led separately to this dispensing opening and is therefore not connected to it Line that leads from the mixing valve to the discharge opening of the fitting body. The functionality of this device with regard to the generation of differently mixed and / or differently tempered liquids that can be dispensed is limited as a result.

Es ist Aufgabe der vorliegenden Erfindung, ein Haushaltsgerät zur Ausgabe von Flüssigkeiten beziehungsweise ein Flüssigkeitsaufbereitungssystem für den Haushalt zu schaffen, bei welchem das Ablassen von restlicher Mischflüssigkeit verbessert ist.The object of the present invention is to create a household appliance for dispensing liquids or a liquid treatment system for the household in which the discharge of residual mixed liquid is improved.

Diese Aufgabe wird durch Haushaltsgeräte gemäß dem unabhängigen Anspruch gelöst.This object is achieved by household appliances according to the independent claim.

Die Erfindung betrifft ein Haushaltsgerät zur Ausgabe von Flüssigkeit. Das Haushaltsgerät weist eine Ausgabeeinheit zum Ausgeben der Flüssigkeit auf. Diese Ausgabeeinheit ist eine Sanitärarmatur. Das Haushaltsgerät weist darüber hinaus eine Anschlussvorrichtung zum Anschließen des Haushaltsgeräts an ein geräteexternes Wassernetz auf. Das Haushaltsgerät weist darüber hinaus ein zur Anschlussvorrichtung separates Wassertemperierungssystem auf. Mit dem Wassertemperierungssystem ist ein von dem geräteexternen Wassernetz dem Wassertemperierungssystem zugeführtes Wasser individuell temperierbar. Das Wassertemperierungssystem weist eine Leitungseinheit auf, mit welcher das Wassertemperierungssystem mit der Ausgabeeinheit verbunden ist. Darüber hinaus weist das Wassertemperierungssystem eine zu dieser Leitungseinheit separate Leitungseinrichtung auf, mit welcher das Wasser des geräteexternen Wassernetzes, insbesondere ohne über das Wassertemperierungssystem geleitet zu werden, direkt von der Anschlussvorrichtung zu der Ausgabeeinheit leitbar ist. Das Wassertemperierungssystem ist an eine Leitung der Ausgabeeinheit mündend, welche zum Leiten einer temperiertes Wasser aus dem Wassertemperierungssystem aufweisenden Flüssigkeit angeordnet ist. Von der Leitung zweigt eine zu dieser Leitung separate Ablassleitung zum Ablassen der nach einem Ausgabevorgang der Flüssigkeit in der Leitung verbliebenen restlichen Flüssigkeit ab. Die Leitung ist eine Mischleitung.The invention relates to a household appliance for dispensing liquid. The household appliance has a dispensing unit for dispensing the liquid. This output unit is a sanitary fitting. The household appliance also has a connection device for connecting the household appliance to an external water network. The household appliance also has a water temperature control system that is separate from the connection device. With the water temperature control system, water supplied to the water temperature control system from the external water network can be individually temperature controlled. The water temperature control system has a line unit with which the water temperature control system is connected to the output unit. In addition, the water temperature control system has a line device separate from this line unit, with which the water of the device-external water network, in particular without being routed via the water temperature control system, can be routed directly from the connection device to the output unit. The water temperature control system opens out on a line of the output unit, which is arranged to conduct a temperature-controlled water from the water temperature control system having liquid. A drain line separate from this line branches off from the line for draining the remaining liquid remaining in the line after the liquid has been dispensed. The line is a mixed line.

Erfindungsgemäß ist die Leitung, an der die Ablassleitung mündet, die Mischleitung. Dies bedeutet, dass sie so im Haushaltsgerät angeordnet bzw. angeschlossen ist, dass auch eine Mischflüssigkeit darin leitbar ist, insbesondere zur Ausgabeöffnung der Ausgabeeinheit direkt leitbar ist. Die Mischflüssigkeit kann aus zumindest zwei separaten Flüssigkeiten, insbesondere aus unterschiedlichen Wassertemperierungssystemen des Haushaltsgeräts gemischt sein. Die restliche Flüssigkeit, die über die Ablassleitung abgelassen werden kann, ist dann eine restliche Mischflüssigkeit.According to the invention, the line at which the discharge line opens is the mixed line. This means that it is arranged or connected in the household appliance in such a way that a mixed liquid can also be conducted therein, in particular can be conducted directly to the dispensing opening of the dispensing unit. The mixed liquid can consist of at least two separate Liquids, in particular from different water temperature control systems of the household appliance, can be mixed. The remaining liquid that can be drained off via the drain line is then a remaining mixed liquid.

Es ist vorgesehen, dass das Wassertemperierungssystem das zur Leitungseinrichtung separate Heißwassersystem aufweist, mit welchem ein von dem geräteexternen Wassernetz zugeführtes Wasser erhitzbar ist. Das Wassertemperierungssystem weist zusätzlich ein zum Heißwassersystem und zur Leitungseinrichtung separates Gekühltwassersystem auf, mit welchem ein von dem geräteexternen Wassernetz zugeführtes Wasser kühlbar ist. Unter einem Gekühltwassersystem wird somit ein System verstanden, mit welchem das von einem geräteexternen Wassernetz zugeführte Wasser aktiv und diesbezüglich auf eine niedrigere Temperatur gekühlt werden kann. Durch ein derartiges nochmals separates System kann auch die Variabilität des Haushaltsgeräts im Hinblick auf unterschiedlichste Temperierungsmöglichkeiten der Flüssigkeiten erhöht werden. Die generelle Flexibilität zur Erzeugung von Mischflüssigkeiten sowohl in der Art als auch in der jeweiligen Temperierung ist dadurch verbessert. Indem dieses Gekühltwassersystem auch separat zum Heißwassersystem und separat zu dieser Leitungseinrichtung, die direkt mit dem geräteexternen Wassernetz verbunden ist, ausgebildet ist, können die einzelnen Temperierungsabläufe in den unterschiedlichen Systemen besonders vorteilhaft erfolgen. Die einzelnen Temperierungen der Flüssigkeiten können sehr effizient und genau erfolgen, sodass dann auch ein mögliches nachfolgendes Mischen von Flüssigkeiten aus diesen Systemen sehr bedarfsgerecht erfolgen kann.It is provided that the water temperature control system has the hot water system which is separate from the line device and with which a water supplied from the water network external to the device can be heated. The water temperature control system also has a cooled water system that is separate from the hot water system and the line device, with which water supplied from the water network external to the device can be cooled. A chilled water system is thus understood to be a system with which the water supplied from a water network external to the device can be actively cooled and, in this regard, to a lower temperature. Such an even more separate system can also increase the variability of the household appliance with regard to the most varied of temperature control options for the liquids. The general flexibility for the generation of mixed liquids both in terms of type and temperature control is improved as a result. Since this cooled water system is also designed separately from the hot water system and separate from this line device, which is directly connected to the external water network, the individual temperature control processes in the different systems can take place particularly advantageously. The individual tempering of the liquids can be carried out very efficiently and precisely, so that a possible subsequent mixing of liquids from these systems can then also take place in a very needs-based manner.

Des Weiteren ist vorgesehen, dass das Heißwassersystem und das Gekühltwassersystem an einer gleichen Mündung an die Mischleitung münden. Es wird somit ein Mischpunkt am Haushaltsgerät erzeugt, in dem ein heißes Wasser aus dem Heißwassersystem und ein gekühltes Wasser aus dem Gekühltwassersystem gemischt werden können und somit diesbezüglich direkt in die Mischleitung eingebracht werden können. Über die Mischleitung kann somit dann eine Mischflüssigkeit geführt werden, die aus dem heißen Wasser des Heißwassersystems und dem Kühlwasser aus dem Gekühltwassersystem gemischt werden kann. Es ist also in dem Haushaltsgerät eine zusätzliche, zweite Möglichkeit geschaffen, Mischflüssigkeit, welche aus den genannten Systemen gemischt werden kann, über diese spezifische Mischleitung auszugeben. Über die Anschlussvorrichtung kann andererseits ebenfalls eine dazu separate Mischflüssigkeit ausgegeben werden, die in vorteilhafter Weise aus dem Wasser, welches aus einer Warmwasserzuleitung der Leitungseinrichtung und aus einem Kaltwasser, welches aus einer Kaltwasserzuleitung der Leitungseinrichtung gemischt werden kann, gemischt werden kann. Die Anschlussvorrichtung ist diesbezüglich mit einer spezifischen Verbindungsleitung mit der Ausgabeeinheit verbunden, wobei diese Verbindungsleitung eine separate Leitung zur oben genannten Leitung, nämlich der Mischleitung, ist.Furthermore, it is provided that the hot water system and the cooled water system open out to the mixed pipe at the same mouth. A mixing point is thus created on the household appliance, in which hot water from the hot water system and cooled water from the cooled water system can be mixed and can therefore be introduced directly into the mixing line in this regard. A mixed liquid, which can be mixed from the hot water from the hot water system and the cooling water from the cooled water system, can thus then be fed via the mixing line. An additional, second possibility is thus created in the household appliance for outputting mixed liquid, which can be mixed from the systems mentioned, via this specific mixed line. Above On the other hand, the connection device can also output a separate mixed liquid, which can advantageously be mixed from the water that can be mixed from a hot water feed line of the line device and from cold water that can be mixed from a cold water feed line of the line device. In this regard, the connection device is connected to the output unit with a specific connecting line, this connecting line being a separate line to the above-mentioned line, namely the mixed line.

Hierbei ist vorgesehen, dass die Mündung, an der die Ablassleitung in die Mischleitung mündet, gleich der Mündung ist, an welcher das Heißwassersystem und das Gekühltwassersystem an die Mischleitung münden. Ein derartiger vollumfänglicher gemeinsamer Mischpunkt ermöglicht eine vereinfachte Leitungsverlegung. Es kann auch vorgesehen sein, dass an einem derartigen umfänglichen gemeinsamen Mischpunkt ebenfalls ein gemeinsames Ventil angeordnet ist, sodass auch hier dann die Anzahl der vorhandenen Ventile reduziert werden kann.It is provided here that the mouth at which the drain line opens into the mixed line is the same as the mouth at which the hot water system and the cooled water system open into the mixed line. Such a complete common mixing point enables simplified wiring. It can also be provided that a common valve is also arranged at such a circumferential common mixing point, so that the number of valves present can then also be reduced here.

Des Weiteren ist vorgesehen, dass zwischen der Mündung und einer Ausgabeöffnung der Ausgabeeinheit ein Ventil in der Mischleitung angeordnet ist. Durch eine derartige Ausgestaltung kann die bedarfsgerechte Zuführung des Heißwassers zu dieser Mischleitung in besonders vorteilhafter Weise ermöglicht werden. Abhängig von der Betriebsstellung dieses Ventils kann eine sehr genaue Dosierung dieses Heißwassers erfolgen.Furthermore, it is provided that a valve is arranged in the mixing line between the mouth and an output opening of the output unit. Such a configuration enables the hot water to be supplied to this mixing line as required in a particularly advantageous manner. Depending on the operating position of this valve, this hot water can be metered very precisely.

Dieses Ventil, welches auch als Spülventil bezeichnet werden kann, ermöglicht somit in besonders bedarfsgerechter Weise das Ablassen der restlichen Flüssigkeit aus der Mischleitung.This valve, which can also be referred to as a flush valve, thus enables the remaining liquid to be drained from the mixing line in a particularly needs-based manner.

Bei dieser Ausgestaltung ist somit neben der Leitung, in der die genannte Flüssigkeit zu einer Ausgabeöffnung der Ausgabeeinheit geleitet wird, eine zusätzliche Ablassleitung vorhanden. Die Ablassleitung ist nicht in direktem Kontakt mit der Ausgabeöffnung der Ausgabeeinheit. Die Ablassleitung mündet entfernt zu der Ausgabeöffnung der Ausgabeeinheit in die Leitung. Die Ablassöffnung der Ablassleitung ist ebenfalls separiert und in keinem Kontakt und in keiner Verbindung mit der Ausgabeöffnung der Ausgabeeinheit. Durch eine derartige Ausgestaltung wird ein Ablassprozess einer nach einem Ausgabevorgang verbliebenen restlichen Flüssigkeit, die sich in der Leitung noch befindet, verbessert. Eine gezielte Abführung aus der Leitung ist vollständig und einfach ermöglicht. Es ist nicht mehr vorgesehen, dass diese restliche Flüssigkeit über die Ausgabeöffnung der Ausgabeeinheit abläuft. Dadurch ist ein unerwünschtes Überlaufen von gegebenenfalls relativ heißer Flüssigkeit über beispielsweise Hände eines Nutzers verhindert. Auch sind ein unerwünschtes Nachträufeln und ein nach dem Ausgabeprozess auslaufendes Rinnsal dieser restlichen Flüssigkeit aus der Ausgabeöffnung der Ausgabeeinheit verhindert. Dadurch wird auch vermieden, dass ein gewisses Ausspritzen beziehungsweise Aufspritzen dieser über die Ausgabeöffnung auslaufenden restlichen Flüssigkeit beispielsweise in einem Becken, in welchem das aus der Ausgabeöffnung der Ausgabeeinheit auslaufende Medium ebenfalls einlaufen könnte, vermieden. Eine erforderliche nachträgliche Reinigung dieses Beckens oder umliegender Bereiche ist dadurch verhindert.In this embodiment, in addition to the line in which the said liquid is conducted to a dispensing opening of the dispensing unit, there is an additional drainage line. The drain line is not in direct contact with the dispensing opening of the dispensing unit. The discharge line opens into the line at a distance to the dispensing opening of the dispensing unit. The discharge opening of the discharge line is also separated and has no contact or connection with the dispensing opening of the dispensing unit. With such a configuration, a draining process becomes after any remaining liquid remaining in the line after a dispensing operation is improved. A targeted discharge from the line is completely and easily made possible. There is no longer provision for this remaining liquid to run off via the dispensing opening of the dispensing unit. This prevents undesired overflow of possibly relatively hot liquid over, for example, the hands of a user. An undesired trickling down and a trickle of this remaining liquid running out of the dispensing opening of the dispensing unit after the dispensing process are also prevented. This also avoids a certain spraying out or splashing of this remaining liquid flowing out via the dispensing opening, for example in a basin in which the medium flowing out of the dispensing opening of the dispensing unit could also flow in. This prevents the need for subsequent cleaning of this basin or the surrounding areas.

Dieses Becken kann beispielsweise ein Spülbecken oder ein anderer Wannenbereich sein.This basin can be, for example, a sink or another tub area.

Die Ausgabeeinheit des Haushaltsgeräts eine Sanitärarmatur, die auch als Wasserhahn bezeichnet werden kann. Durch eine derartige Ausgestaltung wird eine funktionell spezifische Einheit, die grundsätzlich zur Ausgabe von Wasser aus einem damit verbundenen geräteexternen Wassernetz ausgebildet ist, funktionell erweitert.The output unit of the household appliance is a sanitary fitting, which can also be referred to as a faucet. A functionally specific unit, which is basically designed to output water from a connected, device-external water network, is functionally expanded by such a configuration.

Vorzugsweise ist vorgesehen, dass die Ablassleitung in ein zur Ausgabeeinheit separates Restreservoir mündet. Dies ist dahingehend vorteilhaft, dass diese nicht mehr benötigte restliche Flüssigkeit gesammelt werden kann und nicht mehr in eine Einheit des Haushaltsgeräts gelangt, in welcher nachträglich noch benötigte oder für die Ausgabe vorgesehene Flüssigkeit enthalten ist. Dadurch ist es auch ermöglicht, dass in diesem separaten Restreservoir die Flüssigkeit auch sich länger sammeln kann. Dieses separate Restreservoir kann in vorteilhafter Weise für einen Nutzer zugänglich sein, um es entnehmen zu können. Dies kann zu Entsorgungsmaßnahmen der darin gesammelten restlichen Flüssigkeit vorteilhaft sein. Ebenso ist dies für Reinigungszwecke dieses Restreservoirs vorteilhaft.It is preferably provided that the discharge line opens into a residual reservoir separate from the dispensing unit. This is advantageous in that this remaining liquid that is no longer required can be collected and no longer reaches a unit of the household appliance in which liquid that is subsequently still required or intended for dispensing is contained. This also makes it possible for the liquid to be able to collect for a longer period in this separate residual reservoir. This separate residual reservoir can advantageously be accessible to a user in order to be able to remove it. This can be advantageous for disposal measures for the remaining liquid collected therein. This is also advantageous for cleaning purposes of this residual reservoir.

In einer weiteren vorteilhaften Ausführung ist vorgesehen, dass das Restreservoir mit einem geräteexternen Abwassernetz verbunden ist. Dies ist eine weitere sehr vorteilhafte Ausführung, da somit diese verbliebene restliche Flüssigkeit, die auch nicht mehr benötigt wird und insbesondere entsorgt werden soll, direkt und gezielt in ein entsprechend dafür vorgesehenes Abwassernetz, insbesondere ein Haus-Abwassernetz, geleitet werden kann. Insbesondere erfolgt diese Verbindung des Restreservoirs mit dem geräteexternen Abwassernetz derart, dass kein Leitungsweg diesbezüglich zwischen dem Restreservoir und dem geräteexternen Abwassernetz über eine Ausgabeöffnung der Ausgabeeinheit führt.In a further advantageous embodiment it is provided that the remaining reservoir is connected to a waste water network external to the device. This is a further very advantageous embodiment, since this remaining residual liquid, which is also no longer required and in particular is to be disposed of, can be routed directly and specifically into a correspondingly provided waste water network, in particular a domestic waste water network. In particular, this connection of the residual reservoir to the waste water network external to the device takes place in such a way that no line path in this regard leads between the residual reservoir and the external waste water network via an output opening of the output unit.

Vorzugsweise ist vorgesehen, dass die Ablassleitung nicht an eine zumindest zur Ausgabe der Flüssigkeit ausgebildeten Ausgabeöffnung der Ausgabeeinheit mündet. Die diesbezüglichen Vorteile wurden bereits oben dargelegt.It is preferably provided that the discharge line does not open into an output opening of the output unit which is at least designed for outputting the liquid. The advantages in this regard have already been set out above.

Vorzugsweise ist auch das Gekühltwassersystem mit der Leitungseinrichtung verbunden. Es ist dann auch die Möglichkeit geschaffen, dass vom Hauswassernetz kommendes Wasser über die Leitungseinrichtung direkt zur Ausgabeeinheit, insbesondere zur Ausgabeöffnung der Ausgabeeinheit, geleitet wird. Es kann auch vorgesehen sein, dass dann diesbezüglich von dem externen Wassernetz kommendes Wasser von der Leitungseinrichtung zumindest anteilig und insbesondere bedarfsabhängig in das Gekühltwassersystem abgleitet werden kann. Entsprechend gelten diese Erläuterungen dann auch für das Heißwassersystem. Auch dieses kann dann insbesondere mit einer Kaltwasserzuleitung der Anschlussvorrichtung verbunden sein, um diesbezüglich vom geräteexternen Wassernetz über die Kaltwasserzuleitung strömendes Wasser abzuzweigen und in das Heißwassersystem einzuspeisen.The chilled water system is preferably also connected to the line device. It is then also possible for water coming from the domestic water network to be conducted via the line device directly to the dispensing unit, in particular to the dispensing opening of the dispensing unit. It can also be provided that in this regard water coming from the external water network can then be diverted from the line device at least partially and in particular as a function of demand into the chilled water system. These explanations then also apply accordingly to the hot water system. This can also be connected in particular to a cold water supply line of the connection device in order to branch off water flowing from the external water network via the cold water supply line and feed it into the hot water system.

Es kann auch vorgesehen sein, dass das Mischen des Heißwassers und des Gekühltwassers erst an der Ausgabeöffnung oder direkt nach dem Ausgeben aus der Ausgabeöffnung erfolgt.It can also be provided that the hot water and the cooled water are mixed only at the dispensing opening or directly after dispensing from the dispensing opening.

Vorzugsweise ist ein Heißwasseraufbereitungsbehälter, insbesondere ein Boiler, Bestandteil des Heißwassersystems.A hot water preparation container, in particular a boiler, is preferably part of the hot water system.

Vorzugsweise ist vorgesehen, dass die Ablassleitung in Höhenrichtung des Haushaltsgeräts betrachtet vollständig und insbesondere ohne ein Minimum in der Leitung, unterhalb der Mündung, an welcher das Wassertemperierungssystem, insbesondere das Heißwassersystem und das Gekühltwassersystem, an die Leitung münden, angeordnet ist. Dies ist eine besonders vorteilhafte Ausführung, denn dadurch kann das Ablassen der restlichen Flüssigkeit einzig basierend auf der Schwerkraft erfolgen. Es ist keine Pumpe oder eine sonstige fördernde Einheit erforderlich, um diese restliche Flüssigkeit über die Ablassleitung ablassen zu können. Es sind auch keine anderweitigen Konstruktionen, wie sie im Stand der Technik dargelegt sind und beispielsweise mit Unterdruck in einem explizit vorhandenen Behälter arbeiten, erforderlich. Durch eine derartige Ausgestaltung, wie sie oben erwähnt wurde, kann ein hochfunktionelles und dennoch einfaches und bauteilreduziertes Ablasssystem geschaffen werden.It is preferably provided that the drain line, viewed in the vertical direction of the household appliance, is arranged completely and in particular without a minimum in the line, below the mouth at which the water temperature control system, in particular the hot water system and the cooled water system, open onto the line. This is a particularly advantageous embodiment, because it allows the remaining liquid to be drained off solely on the basis of gravity. No pump or other conveying unit is required in order to be able to drain this residual liquid via the drain line. There are also no other constructions, such as those set out in the prior art and, for example, work with negative pressure in an explicitly present container, are required. With such a design, as mentioned above, a highly functional and yet simple and component-reduced drainage system can be created.

Vorzugsweise ist vorgesehen, dass das Haushaltsgerät eine Anzeigeeinheit aufweist, an welcher Informationen zu einer aktuellen oder zukünftigen Frischwasserfüllung des Gekühltwassersystems angezeigt sind. Dadurch ist ein Nutzer des Haushaltsgeräts jederzeit über die Gegebenheiten des Frischwasserbedarfs informiert.It is preferably provided that the household appliance has a display unit on which information on a current or future fresh water filling of the chilled water system is displayed. As a result, a user of the household appliance is informed at all times about the circumstances of the fresh water requirement.

In vorteilhafter Weise ist in der Ablassleitung ein Ventil angeordnet. Ein derartiges Drainageventil ist dahingehend vorteilhaft, dass kein unerwünschtes Auströpfeln oder Auslaufen von Flüssigkeit aus dieser Ablassleitung auftreten würde.A valve is advantageously arranged in the discharge line. Such a drainage valve is advantageous in that no undesired dripping or leakage of liquid would occur from this drainage line.

Vorzugsweise ist vorgesehen, dass dieses Ventil in der Ablassleitung auch direkt an der Mündung, an welcher die Ablassleitung in die Mischleitung mündet, angeordnet ist. Insbesondere können somit die vorteilhaft vorhandenen Ventile in der Mischleitung und der Ablassleitung als ein Ventil zusammengefasst werden.It is preferably provided that this valve is also arranged in the drain line directly at the mouth at which the drain line opens into the mixed line. In particular, the valves advantageously present in the mixing line and the discharge line can thus be combined as one valve.

In einer weiteren vorteilhaften Ausführung kann vorgesehen sein, dass das Haushaltsgerät eine Steuereinheit aufweist, mit welcher zumindest ein Ventil in seiner Betriebsstellung einstellbar ist. Dadurch können sowohl das Ausgeben von Flüssigkeit und/oder das Zuführen von Flüssigkeit zu spezifischen Bereichen im Haushaltsgerät sehr bedarfsgerecht und genau erfolgen.In a further advantageous embodiment it can be provided that the household appliance has a control unit with which at least one valve can be adjusted in its operating position. As a result, both the dispensing of liquid and / or the supply of liquid to specific areas in the household appliance can take place very precisely and in accordance with requirements.

Indem die Steuereinheit dazu ausgebildet ist, unmittelbar vor einer Flüssigkeitsausgabe durch die Ausgabeeinheit mittels Ansteuerung zumindest eines Ventils zumindest eine Leitungseinheit zu spülen, steht an der Ausgabeeinheit mit Beginn der Flüssigkeitsabgabe korrekt temperierte Flüssigkeit zur Verfügung. So wird beispielsweise vermieden, dass bei Bezug von heißem Wasser zuerst das in den dem Boiler nachgelagerten Leitungen vorhandene, über die Zeit erkaltete Wasser ausgegeben wird. Die Steuereinheit öffnet dabei beispielsweise das Wasserzulaufventil für den Boiler, sowie das Drainageventil der Ablassleitung solange, bis die vom Boiler bis zur Mündung von Ablassleitung und Mischleitung führende Leitungseinheit durchgespült ist. Die Spüldauer ist dabei möglichst kurz bemessen und liegt beispielsweise im Bereich von 0,5 bis 2 Sekunden. Alternativ kann die Spüldauer auch durch die Auswertung eines Temperatursensors erfolgen. Bei Erreichen einer vorgegebenen Solltemperatur in der vorgenannten Leitungseinheit steuert die Steuereinheit die Ventile derart an, dass die Flüssigkeitsausgabe ausschließlich über die Ausgabeeinheit erfolgt. Es kann vorgesehen sein, dass die einem Heißwassersystem und einem Gekühltwassersystem jeweils nachgelagerten Leitungen je nach Bedarf einzeln oder aber auch gleichzeitig gespült werden.Since the control unit is designed to flush at least one line unit immediately before a liquid is dispensed by the dispensing unit by activating at least one valve, liquid at the correct temperature is available at the dispensing unit at the beginning of the liquid dispensing. This avoids, for example, that when hot water is drawn off, the water that is present in the lines downstream of the boiler and that has cooled down over time is dispensed first. The control unit opens, for example, the water inlet valve for the boiler and the drainage valve of the drain line until the line unit leading from the boiler to the mouth of the drain line and mixing line is flushed. The flushing time is designed to be as short as possible and is, for example, in the range from 0.5 to 2 seconds. Alternatively, the flushing time can also be carried out by evaluating a temperature sensor. When a predetermined setpoint temperature is reached in the aforementioned line unit, the control unit controls the valves in such a way that the liquid is dispensed exclusively via the dispensing unit. Provision can be made for the lines downstream of a hot water system and a cooled water system to be flushed individually or at the same time as required.

Es kann vorgesehen sein, dass die Leitungseinrichtung eine Kaltwasserleitung und eine dazu separate Warmwasserleitung aufweist, wobei das Wassertemperierungssystem, insbesondere das Heißwassersystem und/oder das Gekühltwassersystem, geräteintern mit der Kaltwasserleitung zur Zuführung von Wasser zu dem Wassertemperierungssystem verbunden sind.It can be provided that the line device has a cold water line and a separate hot water line, the water temperature control system, in particular the hot water system and / or the cooled water system, being connected inside the device to the cold water line for supplying water to the water temperature control system.

In einer vorteilhaften Ausführung ist vorgesehen, dass das Wassertemperierungssystem, insbesondere das Gekühltwassersystem, mit einer Karbonisierungseinheit des Haushaltsgeräts und/oder mit einer Mediumzugabeeinheit des Haushaltsgeräts verbunden ist. Durch die Karbonisierungseinheit kann die Zuführung von Kohlendioxid zu der gekühlten Flüssigkeit in dem Gekühltwassersystem erfolgen, sodass auch ein kohlensäurehaltiges Flüssigkeitsmedium erzeugt und ausgegeben werden kann. Durch die Mediumzugabeeinheit können individuelle Geschmacksnoten beigegeben werden, wobei hier als Medium beispielsweise eine Flüssigkeit oder ein Gel oder ein Pulver als Additiv beigemengt werden kann. Auch andere Additive sind möglich. Bei der Medienzugabeeinheit kann neben den bereits genannten Geschmacksadditiven auch die Zugabe von Mineralien oder Süßstoffen oder dergleichen vorgesehen sein.In an advantageous embodiment it is provided that the water temperature control system, in particular the cooled water system, is connected to a carbonation unit of the household appliance and / or to a medium addition unit of the household appliance. The carbonation unit can supply carbon dioxide to the cooled liquid in the cooled water system, so that a carbonated liquid medium can also be generated and dispensed. The medium addition unit can be used to add individual flavor notes, in which case, for example, a liquid or a gel or a powder can be added as an additive as a medium. Other additives are also possible. In addition to the flavor additives already mentioned, the addition of minerals or sweeteners or the like can also be provided in the media addition unit.

Insbesondere ist das Heißwassersystem derart ausgebildet, dass das darin vorhandene Wasser auf Temperaturen bis über 90° aufgeheizt werden können. Das Gekühltwassersystem ist insbesondere dahingehend ausgebildet, dass das darin befindliche Wasser auf Temperaturen auch unter 10° abgekühlt werden kann.In particular, the hot water system is designed in such a way that the water present therein can be heated to temperatures of over 90 °. The chilled water system is designed in such a way that the water contained therein can also be cooled to temperatures below 10 °.

Vorzugsweise sind die genannten Ventile als elektrische Ventile ausgebildet, die insbesondere über eine bereits erläuterte und dargelegte Steuereinheit ansteuerbar sind. In vorteilhafter Weise ist das bevorzugt vorhandene Ventil in der Ablassleitung in einem Normalbetriebszustand in einer Offenstellung, sodass der Ablauf der abzugebenden restlichen Flüssigkeit in einem derartigen Abgabeprozess stets uneingeschränkt erfolgen kann. Damit wäre auch bei einem Stromausfall das Ablassen dieser restlichen Flüssigkeit über die Ablassleitung ermöglicht. In einer vorteilhaften Ausführung ist vorgesehen, dass dann, wenn, insbesondere über einen Nutzer, ein derartiger Abführ- beziehungsweise Abgabeprozess dieser restlichen Flüssigkeit gestartet werden soll, dieses Ventil in der Ablassleitung geschlossen wird. Dann wird gerade bei Ausführungen, bei denen die Ablassleitung spezifisch in die Mischleitung mündet, ein zumindest teilweise unerwünschtes Ablassen der Flüssigkeit über die Ablassleitung verhindert. Die gesamte Flüssigkeit wird dann über die Mischleitung in die Ausgabeöffnung der Ausgabeeinheit gegeben und dort gewünscht abgelassen. Erst wenn dieser Ausgabeprozess der erzeugten Flüssigkeit, insbesondere der Mischflüssigkeit, über die Ausgabeöffnung der Ausgabeeinheit beendet wird, wird dann dieses Ventil in der Ablassleitung geöffnet und der Abführprozess der restlichen Flüssigkeit über die Ablassleitung ermöglicht.The valves mentioned are preferably designed as electrical valves which can be controlled in particular via a control unit which has already been explained and presented. In an advantageous manner, the valve which is preferably present in the drain line is in an open position in a normal operating state, so that the remaining liquid to be dispensed can always run off without restriction in such a dispensing process. This would enable this remaining liquid to be drained via the drain line even in the event of a power failure. In an advantageous embodiment it is provided that when such a discharge or discharge process of this remaining liquid is to be started, in particular via a user, this valve in the discharge line is closed. Then, especially in the case of designs in which the discharge line specifically opens into the mixing line, an at least partially undesired discharge of the liquid via the discharge line is prevented. All of the liquid is then poured into the dispensing opening of the dispensing unit via the mixing line and drained off there as required. Only when this process of dispensing the generated liquid, in particular the mixed liquid, is ended via the dispensing opening of the dispensing unit, is this valve in the drain line opened and the process of draining the remaining liquid made possible via the drain line.

Eine weitere vorteilhafte Ausgestaltung ist dahingehend erreicht, dass das Gekühltwassersystem auch entsprechend gespült werden kann und dann diese Flüssigkeit, die bei diesem Spülvorgang in dem Gekühltwassersystem zirkuliert, über die Ablassleitung ableitbar ist. Insbesondere ist dann vorgesehen, dass das Gekühltwassersystem mit der Ablassleitung strömungstechnisch verbunden ist, insbesondere an einem gemeinsamen Mündungspunkt beziehungsweise einer gemeinsamen Mündung an die Mischleitung anmünden. Durch eine derartige Spülmöglichkeit kann das Bilden von Keimen und Biofilmen in dem Gekühltwassersystem vermieden werden und eine sehr vorteilhafte Abführung der Flüssigkeit nach dem Spülvorgang extern zur Ausgabeeinheit aus dem Gekühltwassersystem erfolgen. Bei diesem Spülvorgang kann es vorgesehen sein, dass das Haushaltsgerät eine Pumpe aufweist, durch welche das Spülmedium in dem Gekühltwassersystem gefördert wird. Anstelle einer Pumpe kann auch eine Förderung mit Druck vom geräteexternen Wassernetz erfolgen. In einer vorteilhaften Ausführung ist bei einem derartigen Spülvorgang das vorhandene Ventil in der der Mischleitung geschlossen, sodass keine derartige Spülflüssigkeit über die Ausgabeöffnung der Ausgabeeinheit ausgegeben wird. Damit werden das Spülen und auch das Abgeben der Spülflüssigkeit quasi für einen Nutzer unbemerkt durchgeführt, da über die Ausgabeöffnung der Ausgabeeinheit keine derartige Spülflüssigkeit austritt. Bei einer weiteren Ausführung kann vorzugsweise vorgesehen sein, dass die Mischleitung nach dem Bezug einer Flüssigkeit automatisch gefüllt und entleert werden kann. Damit ist es auch möglich, die Ausgabeeinheit, insbesondere wenn sie als Sanitärarmatur als auch von einem Nutzer greifbares Außenbauteil ausgebildet ist, zu kühlen, sodass auch beim Angreifen dieser Ausgabeeinheit sie nicht zu heiß ist. Darüber hinaus kann durch eine derartige Ausgestaltung auch ein Durchspülen der Mischleitung erfolgen, sodass gerade dann, wenn eine insbesondere Mischflüssigkeit mit Additiven, wie sie oben genannt wurden, ausgegeben wurde, ein Verbleib derartiger Additive in der Mischleitung verhindert ist. Auch dadurch kann eine Verfremdung nachträglich auszugebender Flüssigkeiten durch die noch in der Mischleitung vorhandenen Additive verhindert werden und ein Keimwachstum oder das Entstehen von Biofilmen in der Mischleitung aufgrund dieser verbleibenden Additive verhindert werden.A further advantageous embodiment is achieved in that the cooled water system can also be flushed accordingly and then this liquid, which circulates in the cooled water system during this flushing process, can be drained off via the drain line. In particular, it is then provided that the cooled water system is fluidically connected to the discharge line, in particular that it joins the mixed line at a common opening point or a common opening. Such a flushing option can avoid the formation of germs and biofilms in the cooled water system and a very advantageous discharge of the liquid after the flushing process can take place externally to the output unit from the cooled water system. at For this flushing process, it can be provided that the household appliance has a pump through which the flushing medium is conveyed in the cooled water system. Instead of a pump, pressure can also be supplied from the external water network. In an advantageous embodiment, the valve present in the mixing line is closed during such a flushing process, so that no flushing liquid of this type is dispensed via the dispensing opening of the dispensing unit. This means that the rinsing and also the delivery of the rinsing liquid are carried out virtually unnoticed by a user, since no such rinsing liquid emerges via the dispensing opening of the dispensing unit. In a further embodiment, it can preferably be provided that the mixing line can be automatically filled and emptied after a liquid has been drawn off. It is thus also possible to cool the output unit, in particular if it is designed as a sanitary fitting as well as an external component that can be grasped by a user, so that it is not too hot even when this output unit is touched. In addition, such a configuration can also allow the mixing line to be rinsed through, so that especially when a mixed liquid, in particular with additives such as those mentioned above, has been dispensed, such additives are prevented from remaining in the mixing line. In this way, too, alienation of liquids to be subsequently dispensed by the additives still present in the mixing line can be prevented and germ growth or the formation of biofilms in the mixing line due to these remaining additives can be prevented.

Das Haushaltsgerät kann auch so ausgebildet sein, dass es auch dann, wenn es kein Gekühltwassersystem aufweist, eine Karbonisierungseinheit und/oder eine Mediumzugabeeinheit aufweist.The household appliance can also be designed in such a way that it has a carbonation unit and / or a medium addition unit even if it does not have a chilled water system.

Insbesondere ist das Haushaltsgerät insbesondere in der Ausgestaltung mit der Ausgabeeinheit als Sanitärarmatur ein zu einem anderen Haushaltsgerät, beispielsweise einem Haushaltskältegerät oder einem Kaffeevollautomaten separates Haushaltsgerät. Das hiermit oben erläuterte Haushaltsgerät ist somit bei diesen Ausführungen kein Bestandteil eines Haushaltskältegeräts oder eines Kaffeevollautomaten.In particular, the household appliance, in particular in the embodiment with the output unit as a sanitary fitting, is a household appliance that is separate from another household appliance, for example a household refrigerator or a fully automatic coffee machine. The household appliance explained above is therefore not part of a household refrigerator or a fully automatic coffee machine in these designs.

Dadurch kann das erläuterte Haushaltsgerät auch relativ kompakt und platzsparend aufgebaut werden und an Örtlichkeiten im Haushalt verbaut werden, wo derartige Geräte wie Haushaltskältegeräte oder Kaffeevollautomaten nicht verbaut werden können. Insbesondere kann diese Ausgestaltung des Haushaltsgeräts dann auch im Bereich einer Küchenzeile mit einem Spülbecken oder einem sonstigen Auffangbecken angeordnet werden.As a result, the household appliance explained can also be constructed in a relatively compact and space-saving manner and can be installed at locations in the household where such appliances such as household refrigerators or fully automatic coffee machines cannot be installed. In particular, this embodiment of the household appliance can then also be arranged in the area of a kitchen unit with a sink or some other collecting basin.

Ein weiterer Aspekt betrifft ein Haushaltsgerät zur Ausgabe von Flüssigkeit. Es ist somit ein Flüssigkeitsaufbereitungssystem für den Haushalt gebildet. Das Haushaltsgerät weist eine Ausgabeeinheit zum Ausgeben der Flüssigkeit auf. Das Haushaltsgerät weist eine Anschlussvorrichtung zum Anschließen des Haushaltsgeräts an ein geräteexternes Wassernetz auf. Das Haushaltsgerät weist darüber hinaus ein dazu separates Heißwassersystem auf, mit welchem ein von dem geräteexternen Wassernetz zugeführtes Wasser erhitzbar ist. Das Heißwassersystem, welches separat zu dieser Anschlussvorrichtung ausgebildet ist, weist eine Leitungseinheit auf, mit welcher es mit der Ausgabeeinheit verbunden ist. Das Haushaltsgerät weist darüber hinaus eine Leitungseinrichtung auf, die separat zu dieser Leitungseinheit des Heißwassersystems ist. Mit dieser Leitungseinrichtung ist das Wasser des geräteexternen Wassernetzes direkt von der Anschlussvorrichtung zu der Ausgabeeinheit leitbar. Dies bedeutet, dass dieses Wasser dann, ohne über das Heißwassersystem geleitet werden zu müssen, mit der Leitungseinrichtung von der Anschlussvorrichtung zu der Ausgabeeinheit geleitet wird. Das Heißwassersystem ist an eine zum Leiten einer Heißwasser aus dem Heißwassersystem aufweisenden Flüssigkeit angeordneten Leitung, insbesondere der Ausgabeeinheit, mündend. Diese Leitung mündet insbesondere an die Ausgabeöffnung der Ausgabeeinheit. Das Haushaltsgerät weist darüber hinaus eine zu dieser Leitung separate Ablassleitung auf. Diese Ablassleitung ist zum Ablassen der nach einem Ausgabevorgang der Flüssigkeit in der Leitung verbliebenen restlichen Flüssigkeit ausgebildet. Die Ablassleitung zweigt von der Leitung ab.Another aspect relates to a household appliance for dispensing liquid. A liquid treatment system for the household is thus formed. The household appliance has a dispensing unit for dispensing the liquid. The household appliance has a connection device for connecting the household appliance to an external water network. The household appliance also has a separate hot water system with which a water supplied from the external water network can be heated. The hot water system, which is designed separately from this connection device, has a line unit with which it is connected to the output unit. The household appliance also has a line device that is separate from this line unit of the hot water system. With this line device, the water of the external water network can be routed directly from the connection device to the output unit. This means that this water, without having to be routed via the hot water system, is then routed with the line device from the connection device to the dispensing unit. The hot water system empties into a line, in particular the dispensing unit, arranged to convey a liquid containing hot water from the hot water system. This line opens in particular at the output opening of the output unit. The household appliance also has a drain line separate from this line. This drainage line is designed to drain the remaining liquid remaining in the line after the liquid has been dispensed. The drain line branches off from the line.

Ausführungsbeispiele der Erfindung werden nachfolgend anhand einer schematischen Zeichnung näher erläutert.Embodiments of the invention are explained in more detail below with reference to a schematic drawing.

Die einzige Fig. zeigt eine schematische Darstellung eines Haushaltsgeräts 1, welches zur Ausgabe von Flüssigkeit ausgebildet ist. Das Haushaltsgerät 1 kann auch als Flüssigkeitsaufbereitungssystem für den Haushalt bezeichnet werden.The single FIGURE shows a schematic representation of a household appliance 1 which is designed to dispense liquid. The household appliance 1 can also be referred to as a liquid treatment system for the household.

Das Haushaltsgerät 1 weist eine Ausgabeeinheit 2 auf, die insbesondere eine Sanitärarmatur ist. Die Ausgabeeinheit 2 ist im Haushalt als freistehendes Bauteil ausgebildet, welches somit auch ein Sichtbauteil darstellt und gegriffen und betätigt werden kann. Die Ausgabeeinheit 2 weist eine Ausgabeöffnung 3 auf, über welche die Flüssigkeit ausgegeben werden kann. Das Haushaltsgerät 1 weist eine Anschlussvorrichtung 4 auf, die zum Anschließen an ein geräteexternes Wassernetz 5 ausgebildet ist. Zwischen der Anschlussvorrichtung 4 und der Ausgabeeinheit 2 ist eine Leitungseinrichtung 6 angeordnet, mit welcher das Wasser des geräteexternen Wassernetzes 5 direkt und somit ohne über ein vorzugsweise vorhandenes anderes Wassertemperierungssystem des Haushaltsgeräts 1 geleitet zu werden zur Ausgabeeinheit 2 geleitet werden kann. Diese Leitungseinrichtung 6 weist im Ausführungsbeispiel eine Kaltwasserleitung 7 und eine dazu separate Warmwasserleitung 8 auf. Die beiden Leitungen 7 und 8 münden direkt an die Ausgabeeinheit 2. Es kann damit vorgesehen sein, dass nur Wasser aus der Kaltwasserleitung 7 über die Ausgabeöffnung 3 ausgegeben wird oder nur warmes Wasser aus der Warmwasserleitung 8 über die Ausgabeeinheit 3 ausgegeben wird. Es ist auch vorgesehen, dass die Leitungseinrichtung 6 derart ausgebildet ist, dass ein Mischen des warmen Wassers aus der Warmwasserleitung 8 und des kalten Wassers aus der Kaltwasserleitung 7 erfolgt und ein derartiges Mischwasser der Leitungseinrichtung 6 über die Ausgabeöffnung 3 ausgegeben wird.The household appliance 1 has an output unit 2, which is in particular a sanitary fitting. The output unit 2 is designed as a free-standing component in the household, which thus also represents a visible component and can be gripped and operated. The dispensing unit 2 has a dispensing opening 3 through which the liquid can be dispensed. The household appliance 1 has a connection device 4 which is designed for connection to a water network 5 external to the device. Between the connection device 4 and the output unit 2 there is a line device 6 with which the water of the external water network 5 can be passed to the output unit 2 directly and thus without being passed via another water temperature control system of the household appliance 1 that is preferably present. In the exemplary embodiment, this line device 6 has a cold water line 7 and a separate hot water line 8. The two lines 7 and 8 open directly to the dispensing unit 2. It can thus be provided that only water is dispensed from the cold water line 7 via the dispensing opening 3 or only warm water is dispensed from the hot water line 8 via the dispensing unit 3. It is also provided that the line device 6 is designed in such a way that the warm water from the hot water line 8 and the cold water from the cold water line 7 are mixed and such mixed water from the line device 6 is output via the dispensing opening 3.

Darüber hinaus weist das Haushaltsgerät 1 zumindest ein Wassertemperierungssystem 9 auf, welches als separates System zur Leitungseinrichtung 6 ausgebildet ist. Das Wassertemperierungssystem 9 ist mit einer Leitung 10 verbunden. Die Leitung 10 ist insbesondere eine Mischleitung und somit so in dem Haushaltsgerät 1 angeordnet und angeschlossen, dass eine aus zumindest zwei Flüssigkeiten gemischte Mischflüssigkeit darin geleitet wird. Die Leitung 10 ist mit der Ausgabeeinheit 2 verbunden. Flüssigkeit aus dem Wassertemperierungssystem 9 kann somit über die separate Leitung 10 zur Ausgabeeinheit 2 und dort über die Ausgabeöffnung 3 ausgegeben werden. Die Leitung 10 ist eine zu der Leitungseinrichtung 6 separate Leitung, die auch zu der Kaltwasserleitung 7 und der Warmwasserleitung 8 in der Ausgabeeinheit 2 separat ist und somit insbesondere separat auch in die Ausgabeöffnung 3 mündet.In addition, the household appliance 1 has at least one water temperature control system 9, which is designed as a separate system for the line device 6. The water temperature control system 9 is connected to a line 10. The line 10 is in particular a mixed line and is thus arranged and connected in the household appliance 1 in such a way that a mixed liquid mixed from at least two liquids is passed therein. The line 10 is connected to the output unit 2. Liquid from the water temperature control system 9 can thus be dispensed via the separate line 10 to the dispensing unit 2 and there via the dispensing opening 3. The line 10 is a line separate from the line device 6, which is also separate from the cold water line 7 and the hot water line 8 in the dispensing unit 2 and thus in particular also opens separately into the dispensing opening 3.

Im Ausführungsbeispiel ist vorgesehen, dass das Haushaltsgerät 1 zwei Wassertemperierungssysteme aufweist, nämlich ein Heißwassersystem 11 und ein dazu separates Gekühltwassersystem 12. Das Heißwassersystem 11 und das Gekühltwassersystem 12 sind getrennt voneinander und stellen auch separate Systeme zur Leitungseinrichtung 6 dar. Wie in der Fig. zu erkennen ist, ist das Heißwassersystem 11 an einer Mündung 13, die stromabwärts der Anschlussvorrichtung 4 ist, mit der Kaltwasserleitung 7 verbunden. Dadurch ist es möglich, dass kaltes Wasser aus der Kaltwasserleitung 7 abgezweigt wird und dem Heißwassersystem 11 zugeführt wird. Das Heißwassersystem 11 mündet andererseits an der Mündung 14 in die Leitung 10. Das Heißwassersystem 11 weist einen Heißwasseraufbereitungsbehälter, insbesondere einen Boiler 15, auf. Dieser Boiler 15 ist mit einer Zuleitung 16 verbunden, die an die Mündung 13 mündet. Darüber hinaus weist das Heißwassersystem 11 eine Leitungseinheit 17 auf, die zwischen dem Boiler 15 und der Mündung 14 verläuft. In der Leitungseinheit 17 ist ein Ventil 20 angeordnet.In the exemplary embodiment, it is provided that the household appliance 1 has two water temperature control systems, namely a hot water system 11 and a separate cooled water system 12. The hot water system 11 and the cooled water system 12 are separate from one another and also represent separate systems for the line device 6 As can be seen, the hot water system 11 is connected to the cold water line 7 at an opening 13 which is downstream of the connection device 4. This makes it possible for cold water to be branched off from the cold water line 7 and fed to the hot water system 11. On the other hand, the hot water system 11 discharges into the line 10 at the mouth 14. The hot water system 11 has a hot water preparation container, in particular a boiler 15. This boiler 15 is connected to a feed line 16 which opens at the mouth 13. In addition, the hot water system 11 has a line unit 17 which runs between the boiler 15 and the mouth 14. A valve 20 is arranged in the line unit 17.

In der Zuleitung 16 ist ein Ventil 18 angeordnet. In dem Boiler 15 ist vorzugsweise ein Filter 19 angeordnet.A valve 18 is arranged in the supply line 16. A filter 19 is preferably arranged in the boiler 15.

Darüber hinaus ist vorgesehen, dass das Gekühltwassersystem 12 ebenfalls mit der Kaltwasserleitung 7 verbunden ist, insbesondere auch an der Mündung 13. Dadurch kann kaltes Wasser aus der Kaltwasserleitung 7 dem Gekühltwassersystem 12 zugeführt werden und dort auf eine gewünschte niedrigere Temperatur abgekühlt werden. Das Gekühltwassersystem 12 weist hier einen Kältekreislauf 21 mit insbesondere einem Kompressor 22, einem Verflüssiger 23 und einem Verdampfer 24 auf. Darüber hinaus weist das Gekühltwassersystem 12 einen Vorratsbehälter bzw. einen Behälter 25 auf, der mit dem Kältekreislauf 21 thermisch gekoppelt ist und in dem das über eine Zuleitung 26 zugeführte Wasser durch den Kältekreislauf 21 abgekühlt werden kann. Durch eine weitere Leitungseinheit 27 ist der Behälter 25 mit der Leitung 10 verbunden, insbesondere mündet diese Leitungseinheit 27 an die Mündung 14. In dieser Leitungseinheit 27 ist ein Ventil 28 angeordnet.In addition, it is provided that the chilled water system 12 is also connected to the cold water line 7, in particular also at the mouth 13. This allows cold water from the cold water line 7 to be fed to the chilled water system 12 and cooled there to a desired lower temperature. The cooled water system 12 here has a cooling circuit 21 with, in particular, a compressor 22, a condenser 23 and an evaporator 24. In addition, the cooled water system 12 has a storage tank or a container 25 which is thermally coupled to the cooling circuit 21 and in which the water supplied via a supply line 26 can be cooled by the cooling circuit 21. The container 25 is connected to the line 10 by a further line unit 27, in particular this line unit 27 opens out at the opening 14. A valve 28 is arranged in this line unit 27.

Insbesondere weist das Haushaltsgerät 1 darüber hinaus eine Ablassleitung 29 auf, die eine zur Leitung 10 separate Leitung ist. Im Ausführungsbeispiel mündet diese Ablassleitung 29 an die Mündung 14. Vorzugsweise ist in dieser Ablassleitung 29 ein Ventil 30 angeordnet. In der gezeigten Ausgestaltung ist diese Ablassleitung 29 ohne direkte Verbindung mit der Ausgabeeinheit 2. Über diese Ablassleitung 29 kann restliche Flüssigkeit, insbesondere restliche Mischflüssigkeit, die sich nach einem Ausgabeprozess von der Flüssigkeit über die Leitung 10, nämlich die Mischleitung, und die Ausgabeöffnung 3 in der Leitung 10 noch befindet, ohne über die Ausgabeeinheit 2, insbesondere ohne über die Ausgabeöffnung 3, abgelassen zu werden, abgeführt beziehungsweise abgelassen werden. Vorzugsweise mündet die Ablassleitung 29 in ein separates Restreservoir 31, welches mit einem geräteexternen Abwassernetz verbunden sein kann oder das geräteexterne Abwassernetz sein kann. Diese restliche verbliebene Flüssigkeit in der Leitung 10 wird somit nicht über die Ausgabeöffnung 3 der Ausgabeeinheit 2 abgeführt, sondern extern dazu. In der Leitung 10 ist in einer vorteilhaften Ausführung ein Ventil 32 angeordnet. Es kann vorgesehen sein, dass zumindest die beiden Ventile 30 und 32 ein gemeinsames Ventil sind und an der Mündung 14 dieses Ventil angeordnet ist. Es kann auch vorgesehen sein, dass das Ventil 28 an der Mündung 14 angeordnet ist und insbesondere mit den Ventilen 30 und 32 zu einem gemeinsamen Ventil zusammengefasst ist.In particular, the household appliance 1 also has a drain line 29, which is a line separate from the line 10. In the exemplary embodiment, this discharge line 29 opens at the mouth 14. This discharge line 29 is preferably a Valve 30 arranged. In the embodiment shown, this drainage line 29 is without a direct connection to the dispensing unit 2. Via this drainage line 29, residual liquid, in particular residual mixed liquid, which after a dispensing process is separated from the liquid via the line 10, namely the mixing line, and the dispensing opening 3 in the line 10 is still located, without being discharged via the output unit 2, in particular without being discharged or discharged via the output opening 3. The drain line 29 preferably opens into a separate residual reservoir 31, which can be connected to a waste water network external to the device or can be the external waste water network. This remaining liquid in the line 10 is thus not discharged via the dispensing opening 3 of the dispensing unit 2, but rather externally. In an advantageous embodiment, a valve 32 is arranged in the line 10. It can be provided that at least the two valves 30 and 32 are a common valve and that this valve is arranged at the mouth 14. It can also be provided that the valve 28 is arranged on the mouth 14 and, in particular, is combined with the valves 30 and 32 to form a common valve.

Über die Leitung 10 kann separat und unabhängig von der Ausgabe eines Mischwassers über die Leitungseinrichtung 6 zur Ausgabeeinheit 2 hier auch eine Mischflüssigkeit ausgegeben werden, die durch Flüssigkeit aus dem Heißwassersystem 11 und Flüssigkeit aus dem Gekühltwassersystem 12 gemischt ist.Via the line 10, a mixed liquid can also be output here separately and independently of the output of mixed water via the line device 6 to the output unit 2, which is mixed by liquid from the hot water system 11 and liquid from the cooled water system 12.

In besonderer Vorteilhaftigkeit, die nicht beansprucht ist, ist vorgesehen, dass die Ablassleitung 29 vollständig unterhalb der Mündung 14, an welcher sie in die Leitung 10 mündet, angeordnet ist. Insbesondere ist die Ablassleitung 29 in dieser vertikalen Richtung (y-Richtung) auch ohne ein Leitungsminimum ausgebildet. Das Ablassen der restlichen Flüssigkeit aus der Leitung 10 über die Ablassleitung 29 kann daher in besonders vorteilhafter Weise rein durch die Schwerkraft bedingt erfolgen. Insbesondere stellt somit ein mit der Mündung 14 verbundener Eingang der Ablassleitung 29 den in vertikaler Richtung höchsten Punkt der Ablassleitung 29 dar und ein dieser Mündung 14 abgewandter und dem vorzugsweise vorhandenen Restreservoir 31 zugewandter Ausgang dieser Ablassleitung 29 den in vertikaler Richtung tiefsten Punkt dieser Ablassleitung 29 dar. Die mit den vorzugsweise vorhandenen Ventilen 30 und 32, die auch als gemeinsames einziges Ventil ausgebildet sein können, erreichbaren Betriebsmöglichkeiten zum Zuführen, Ablassen und Ausgeben von Flüssigkeit aus der Ausgabeeinheit 2 und/oder der Ablassleitung 29 wurden bereits oben erläutert. Insbesondere ist über das Ventil 28 und die Ablassleitung 29, insbesondere mit dem Ventil 30, auch ein Spülvorgang des Gekühltwassersystems 12 ermöglicht, wie er ebenfalls bereits oben dargelegt wurde.In a particular advantage, which is not claimed, it is provided that the discharge line 29 is arranged completely below the mouth 14 at which it opens into the line 10. In particular, the discharge line 29 is also formed without a line minimum in this vertical direction (y-direction). The draining of the remaining liquid from the line 10 via the drainage line 29 can therefore take place in a particularly advantageous manner purely due to the force of gravity. In particular, an inlet of the discharge line 29 connected to the mouth 14 represents the highest point of the discharge line 29 in the vertical direction and an outlet of this discharge line 29 facing away from this mouth 14 and facing the preferably existing residual reservoir 31 represents the lowest point of this discharge line 29 in the vertical direction Those achievable with the valves 30 and 32, which are preferably present and which can also be designed as a single common valve Operating options for supplying, draining and dispensing liquid from the dispensing unit 2 and / or the drain line 29 have already been explained above. In particular, a flushing process of the cooled water system 12 is also made possible via the valve 28 and the drain line 29, in particular with the valve 30, as has also already been explained above.

Das Haushaltsgerät 1 weist darüber hinaus insbesondere eine Anzeigeeinheit 33 auf, an der beispielsweise Temperaturen von heißem Wasser im Heißwassersystem 11 und/oder Temperaturen des gekühlten Wassers im Gekühltwassersystem 12 anzeigbar sind. Darüber hinaus können hier auch noch weitere Informationen angezeigt werden. Die Anzeigeeinheit 33 kann zusätzlich auch als Eingabeeinheit ausgebildet sein, über welche ein Nutzer Einstellungen vornehmen kann. Insbesondere ist eine Anzeige- und/oder Einstelleinrichtung ausgebildet. Insbesondere können hier dann beispielsweise Temperaturen einer auszugebenden Mischflüssigkeit, die aus einem Heißwasser des Heißwassersystems 11 und einem Gekühltwasser aus dem Gekühltwassersystem 12 gemischt werden soll, eingegeben und/oder angezeigt werden. Darüber hinaus kann vorzugsweise zusätzlich dann auch noch eine Eingabe erfolgen, welche gegebenenfalls vorhandenen Additive dieser Mischflüssigkeit zugegeben werden sollen und/oder ob die Mischflüssigkeit karbonisiert sein soll.The household appliance 1 also has, in particular, a display unit 33 on which, for example, temperatures of hot water in hot water system 11 and / or temperatures of the chilled water in chilled water system 12 can be displayed. In addition, further information can also be displayed here. The display unit 33 can additionally also be designed as an input unit, via which a user can make settings. In particular, a display and / or setting device is designed. In particular, temperatures of a mixed liquid to be output, which is to be mixed from hot water from hot water system 11 and cooled water from cooled water system 12, can then be entered and / or displayed. In addition, an input can then preferably also be made as to which additives, if any, are to be added to this mixed liquid and / or whether the mixed liquid should be carbonized.

Das Haushaltsgerät 1 weist eine Steuereinheit 34 auf, mittels welcher das Haushaltsgerät 1 steuerbar ist. Insbesondere können hier Ausgabeprozesse und/oder Mischungsprozesse entsprechend gesteuert werden. Dazu können das Heißwassersystem 11 und das Gekühltwassersystem 12 entsprechend gesteuert werden. Vorzugsweise werden hier dann die entsprechenden Ventile 18, 20 und insbesondere auch 28 entsprechend angesteuert. Das Ventil 20 ist hier in der Leitungseinheit 17 zwischen dem Boiler 15 und der Mündung 14 angeordnet.The household appliance 1 has a control unit 34 by means of which the household appliance 1 can be controlled. In particular, output processes and / or mixing processes can be controlled accordingly here. For this purpose, the hot water system 11 and the cooled water system 12 can be controlled accordingly. The corresponding valves 18, 20 and in particular also 28 are then preferably activated accordingly. The valve 20 is arranged here in the line unit 17 between the boiler 15 and the mouth 14.

Zusätzlich wird insbesondere dann auch der Kältekreislauf 21 des Gekühltwassersystems 12 durch die Steuereinheit 34 gesteuert. Die Steuereinheit 34 kann eine einzige Steuereinheit sein, sie kann jedoch als übergeordnetes Steuerungssystem aus mehreren Steuereinheiten ausgebildet sein.In addition, the cooling circuit 21 of the cooled water system 12 is then also controlled in particular by the control unit 34. The control unit 34 can be a single control unit, but it can be designed as a higher-level control system made up of a plurality of control units.

Insbesondere weist das Haushaltsgerät 1 darüber hinaus eine Karbonisierungseinheit 35 auf, die insbesondere mit dem Gekühltwassersystem 12, vorzugsweise der Leitungseinheit 27, verbunden ist. In einer entsprechenden Verbindungsleitung kann ein Ventil 36 angeordnet sein. Die gekühlte Flüssigkeit vom Gekühltwassersystem 12,die über die Mischleitung 10, die die Ausgabeleitung darstellt, ausgegeben werden soll, kann hier dann auch karbonisiert sein.In particular, the household appliance 1 also has a carbonation unit 35, which is connected in particular to the chilled water system 12, preferably the line unit 27. A valve 36 can be arranged in a corresponding connecting line. The cooled liquid from the cooled water system 12, which is to be output via the mixing line 10, which represents the output line, can then also be carbonized here.

Darüber hinaus kann das Haushaltsgerät 1 eine Mediumzugabeeinheit 37 aufweisen, die insbesondere ebenfalls vorzugsweise mit dem Gekühltwassersystem 12 verbunden ist. Auch hier kann in der entsprechenden Leitung ein Ventil 38 angeordnet sein.In addition, the household appliance 1 can have a medium addition unit 37 which, in particular, is also preferably connected to the chilled water system 12. Here, too, a valve 38 can be arranged in the corresponding line.

Vorzugsweise ist die Mediumzugabeeinheit 37 mit der Leitungseinheit 27, die sich von dem Behälter 25 zu der Mündung 14 erstreckt, verbunden.The medium addition unit 37 is preferably connected to the line unit 27, which extends from the container 25 to the mouth 14.
