Description

Die Erfindung betrifft einen Geschirrspülautomaten mit einem Spülbehälter, einem Dampfkondensator und einem Trocknungsgebläse, wobei der Spülbehälter einen Spülraum bereitstellt, mit dem der Dampfkondensator und das Trocknungsgebläse in strömungstechnischer Verbindung stehen, wobei das Trocknungsgebläse zwei Schaltstufen aufweist und der Dampfkondensator über eine Sprühwasserdüse verfügt. Die Erfindung betrifft des Weiteren ein Verfahren zum Betrieb eines mit einem Dampfkondensator und einem Trocknungsgebläse ausgerüsteten Geschirrspülautomatens.The invention relates to a dishwasher with a rinsing container, a steam condenser and a drying fan, the rinsing container providing a rinsing space with which the steam condenser and the drying fan are in fluid communication, wherein the drying fan has two switching stages and the steam condenser has a Sprühwasserdüse. The invention further relates to a method for operating a dishwasher equipped with a steam condenser and a drying fan.

Geschirrspülautomaten der eingangs genannten Art sind aus dem Stand der Technik an sich bekannt, auch in der Ausgestaltung als Gewerbespülmaschinen.Dishwashers of the type mentioned are known from the prior art, even in the embodiment as Gewerbespülmaschinen.

Der letzte Spülschritt eines Spülprogramms endet häufig mit einer hohen Spülflottentemperatur von zum Beispiel 93°C. Bevor zur Unterstützung einer Spülguttrocknung das Trocknungsgebläse anlaufen kann, ist es ob der hohen Spülflottentemperatur im letzten Spülschritt erforderlich, den im Spülraum des Geschirrspülautomaten befindlichen Dampf zunächst abzuziehen und zu kondensieren. Zu diesem Zweck kommt bei vorbekannten Geschirrspülautomaten ein Dampfkondensator zum Einsatz, der mit dem vom Spülbehälter bereitgestellten Spülraum in strömungstechnischer Verbindung steht.The final rinse step of a wash program often ends with a high rinse bath temperature of, for example, 93 ° C. Before the drying fan can start to assist a Spülguttrocknung, it is necessary if the high rinsing liquor temperature in the last rinsing step to first remove the steam located in the dishwasher dishwasher washing compartment and to condense. For this purpose, in previously known automatic dishwashers a steam condenser is used, which is in fluid communication with the washing compartment provided by the washing compartment.

Der Dampfkondensator verfügt über eine Sprühwasserdüse. Im Betriebsfall wird durch die Sprühwasserdüse ein Unterdruck im Dampfkondensator erzeugt, infolgedessen es aufgrund der strömungstechnischen Verbindung des Dampfkondensators mit dem vom Spülbehälter bereitgestellten Spülraum zu einem Absaugen des im Spülraum befindlichen Dampfes in den Dampfkondensator kommt. Hier erfolgt dann ein Kondensieren des Dampfes.The steam condenser has a spray water nozzle. In case of operation, a negative pressure in the steam condenser is generated by the Sprühwasserdüse, as a result of which comes due to the fluidic connection of the steam condenser with the washing compartment provided by the washing compartment to a suction of the steam located in the washing chamber in the steam condenser. Here then takes place a condensation of the steam.

Obgleich sich Geschirrspülautomaten der eingangs genannten Art im alltäglichen Praxiseinsatz bewährt haben, besteht Verbesserungsbedarf. Insbesondere die Dampfabsaugung benötigt verhältnismäßig lang. Eine Verkürzung ist deshalb angestrebt. Ferner bedingt die verhältnismäßig lange Dampfabsaugung eine entsprechend lange Ansteuerzeit der Sprühwasserdüse, was sich in einem erhöhten Wasserverbrauch niederschlägt. Auch dies ist verbesserungswürdig.Although automatic dishwashers of the type mentioned have proven themselves in everyday practical use, there is room for improvement. In particular, the steam extraction requires relatively long. Shortening is therefore desired. Furthermore, the relatively long steam extraction causes a correspondingly long activation time of the spray nozzle, which is reflected in increased water consumption. This too is in need of improvement.

Es ist deshalb ausgehend vom Vorbeschriebenen die Aufgabe der Erfindung, einen Geschirrspülautomaten der eingangs genannten Art dahingehend weiterzuentwickeln, dass eine schnellere Dampfabsaugung erreicht wird.It is therefore on the basis of the above, the object of the invention to further develop a dishwasher of the type mentioned in that a faster vapor extraction is achieved.

Zur Lösung wird mit der Erfindung ein Geschirrspülautomat der eingangs genannten Art vorgeschlagen, der sich dadurch auszeichnet, dass der im Betriebsfall von der Sprühwasserdüse des Dampfkondensators abgegebene Wasservolumenstrom auf den vom Trocknungsgebläse gemäß einer ersten Schaltstufe geförderten Volumenstrom abgestimmt ist, so dass im Spülraum ein Unterdruck ausgebildet ist.To solve the invention, a dishwashing machine of the type mentioned is proposed, which is characterized in that the output during operation of the spray nozzle of the steam condenser water volume flow is adjusted to the volume delivered by the drying fan according to a first switching stage, so that formed a vacuum in the washing compartment is.

Die erfindungsgemäße Ausgestaltung gestattet es, das Trocknungsgebläse im Unterschied zum Stand der Technik nicht erst nach erfolgter Dampfabsaugung einzusetzen, sondern das Trocknungsgebläse vielmehr bereits zum Zwecke der Dampfabsaugung einzusetzen. Im Ergebnis kann so eine sehr viel schnellere Dampfabsaugung erreicht werden, was einerseits den Vorteil eines insgesamt verkürzten Programmablaufes und andererseits einen verringerten Wasserverbrauch mit Blick auf einen Betrieb der Sprühwasserdüse mit sich bringt.The inventive design makes it possible not to use the drying fan in contrast to the prior art after the steam extraction, but rather to use the drying fan already for the purpose of vapor extraction. As a result, a much faster vapor extraction can be achieved, which on the one hand brings with it the advantage of an overall shortened program sequence and, on the other hand, a reduced water consumption with regard to operation of the spray nozzle.

Durch das Trocknungsgebläse wird im Betriebsfall ein Überdruck ausgebildet. Bei einem ausschließlichen Betrieb nur des Trocknungsgebläses würde folglich die Gefahr eines unkontrollierten Dampfaustrags beispielsweise über die Türdichtung bestehen. Es ist deshalb erfindungsgemäß vorgesehen, dass der im Betriebsfall von der Sprühwasserdüse des Dampfkondensators abgegebene Wasservolumenstrom auf den vom Trocknungsgebläse geförderten Volumenstrom abgestimmt ist, und zwar derart, dass im Spülraum ein Unterdruck ausgebildet ist. Der durch den Volumenstrom des Trocknungsgebläses erzeugte Überdruck ist damit kleiner als der durch den Betrieb der Sprühwasserdüse erzeugte Unterdruck. Im Ergebnis herrscht damit in Summe im Spülraum ein Unterdruck, so dass der darin befindliche Dampf in den Dampfkondensator abgesogen wird, und dies in erfindungsgemäßer Weise mit Unterstützung des Trocknungsgebläses, so dass im Ergebnis eine erhebliche Verkürzung des Programmschrittes der Dampfabsaugung erreicht werden kann.By the drying fan, an overpressure is formed during operation. In the case of an exclusive operation of only the drying blower, there would consequently be the risk of an uncontrolled discharge of steam, for example via the door seal. It is therefore provided according to the invention that the output in the case of operation of the spray nozzle of the steam condenser water volume flow is adjusted to the volume delivered by the drying fan flow, in such a way that a vacuum is formed in the washing compartment. The excess pressure generated by the volume flow of the drying blower is thus smaller than the negative pressure generated by the operation of the spray nozzle. As a result, there is a total negative pressure in the washing chamber, so that the steam contained therein is sucked into the steam condenser, and this in accordance with the invention with the assistance of the drying blower, so that as a result a significant reduction of the program step of the vapor extraction can be achieved.

Die Ausbildung des Unterdrucks im Spülraum erbringt dabei den Vorteil, dass im Spülraum befindlicher Dampf nicht über etwaige Undichtigkeiten wie zum Beispiel die Türdichtung für den Verwender sichtbar nach außen gelangen kann. Der Dampf verbleibt aufgrund der ausgebildeten Druckverhältnisse vielmehr vollständig im Spülraum und kann in vorbeschriebener Weise zum Zwecke der Kondensation in den Dampfkondensator überführt werden.The formation of the negative pressure in the washing compartment thereby provides the advantage that steam located in the washing compartment can not be visibly exposed to the outside via any leaks, such as, for example, the door seal for the user. Rather, due to the pressure conditions formed, the vapor remains completely in the washing compartment and can be transferred into the steam condenser in the manner described above for the purpose of condensation.

Das Trocknungsgebläse verfügt über mehrere Schaltstufen. Es sind bevorzugterweise zwei Schaltstufen vorgesehen, wobei aber auch eine Vielzahl solcher Schaltstufen möglich sind. Bei einer zweistufigen Ausgestaltung des Trocknungsgebläses entspricht die erste Schaltstufe beispielsweise einem Volumenstrom von 7 bis 10 m3/h. In der zweiten Schaltstufe wird ein Volumenstrom von ca. 75 m3/h erreicht.The drying fan has several switching stages. There are preferably provided two switching stages, but also a plurality of such switching stages are possible. In a two-stage embodiment of the drying blower, the first switching stage corresponds for example to a volume flow of 7 to 10 m 3 / h. In the second switching stage, a volume flow of about 75 m 3 / h is achieved.

Gemäß der erfindungsgemäßen Ausgestaltung erfolgt zunächst ein Betrieb des Trocknungsgebläses in einer ersten Schaltstufe bei beispielsweise 7 bis 10 m3/h. Sobald der Dampf abgesogen und vollständig kondensiert ist, die Gefahr eines Dampfaustritts nach außen also nicht mehr besteht, kann zum Zwecke einer beschleunigten Trocknung des im Spülraum befindlichen Spülgutes von der ersten Schaltstufe auf die zweite Schaltstufe umgeschaltet werden. Gemäß der zweiten Schaltstufe wird dann ein Volumenstrom des Trocknungsgebläses von ca. 75 m3/h erreicht, was im Ergebnis eine schnellere Trocknung mit sich bringt.According to the embodiment of the invention, the first operation of the drying blower in a first switching stage, for example, 7 to 10 m 3 / h. As soon as the steam has been sucked off and completely condensed, the danger of a steam outlet to the outside therefore no longer exists, it is possible to switch from the first switching stage to the second switching stage for the purpose of accelerated drying of the items to be washed in the washing compartment. According to the second switching stage, a volume flow of the drying blower of about 75 m 3 / h is then achieved, which results in a faster drying with it.

Systembedingt wird der vom Trocknungsgebläse erzeugte Volumenstrom durch den Dampfkondensator geführt, auch wenn es bereits zu einer vollständigen Kondensation des Dampfes im vorangegangenen Schritt der Dampfbeseitigung gekommen ist. Da der Dampfkondensator strömungstechnisch nicht auf die bloße Hindurchführung von Trocknungsluft optimiert ausgelegt ist, kommt es im Dampfkondensator zu deutlichen Druckverlusten. Dabei sind die Druckverluste mit steigendem Volumenstrom umso größer. Um hier Abhilfe zu schaffen, wird gemäß einem weiteren Merkmal der Erfindung vorgeschlagen, dass der Dampfkondensator und der vom Spülbehälter bereitgestellte Spülraum über einen Bypass in strömungstechnischer Verbindung stehen. Über diesen Bypass kann während der Trocknungsphase ein Teil des vom Trocknungsgebläse geförderten Volumenstroms geführt werden. Unter Abkürzung des Dampfkondensators wird so zumindest für einen Teil des Volumenstroms ein Strömungsweg geschaffen, der deutlich reduzierte Druckverluste mit sich bringt. Hierdurch wird eine Steigerung des Volumenstroms des Trocknungsgebläses erreicht, was im Ergebnis eine Verkürzung des Trocknungsvorganges mit sich bringt.Due to the system, the volume flow generated by the drying fan is guided through the steam condenser, even if complete condensation of the steam has already occurred in the previous step of steam removal. Since the steam condenser is not designed to be optimized for the mere passage of drying air, it comes to significant pressure losses in the steam condenser. The pressure losses are greater with increasing volume flow. To remedy this situation, it is proposed according to a further feature of the invention that the steam condenser and the washing compartment provided by the washing compartment are in fluid communication via a bypass. During the drying phase, a part of the volume flow delivered by the drying fan can be guided via this bypass. By abbreviation of the steam condenser, a flow path is thus created, at least for part of the volume flow, which entails significantly reduced pressure losses. As a result, an increase in the volume flow of the drying blower is achieved, which results in a shortening of the drying process with it.

Der Bypass verschließt gemäß einem weiteren Merkmal der Erfindung bevorzugterweise druckabhängig, vorzugsweise abhängig von der Druckdifferenz zwischen Dampfkondensator und Spülbehälter. So kann beispielsweise vorgesehen sein, dass der Bypass bei einer Druckdifferenz zwischen Dampfkondensator und Spülbehälter von ca. 5 bis 6 mbar öffnet, das heißt dann öffnet, wenn der Druck im Dampfkondensator ca. 5 bis 6 mbar über dem Druck im Spülbehälter liegt. Im Ergebnis der Bypassöffnung wird ein Teil des Volumenstroms unter Abkürzung des Dampfkondensators umgewälzt, was zu einem Druckabfall im Dampfkondensator führt, im Ergebnis also eine Reduzierung des Gegendrucks erreicht wird, gegen welchen das Trocknungsgebläse anarbeiten muss.The bypass closes according to a further feature of the invention preferably pressure-dependent, preferably depending on the pressure difference between the steam condenser and washing. For example, it may be provided that the bypass opens at a pressure difference between the steam condenser and the rinse tank of about 5 to 6 mbar, that is opens when the pressure in the steam condenser is about 5 to 6 mbar above the pressure in the washing. As a result of the bypass opening, a part of the volume flow is circulated by shortening the steam condenser, resulting in a Pressure drop in the steam condenser results in a result so that a reduction of the back pressure is achieved, against which the drying fan has to work.

Gemäß einem weiteren Merkmal der Erfindung ist vorgesehen, dass der Dampfkondensator über eine zweite Sprühwasserdüse verfügt. Es ist dabei bevorzugt, dass die erste und die zweite Sprühwasserdüse mit Bezug auf die Strömungsrichtung des durch den Dampfkondensator geführten Volumenstroms einander gegenüberliegend ausgerichtet sind. Auf diese Weise kann eine optimierte Kühlung und damit Auskondensation des durch den Dampfkondensator geführten Dampfes erreicht werden. Dabei ist die zweite Sprühwasserdüse, die in Gegenstromrichtung zur ersten Sprühwasserdüse ausgerichtet ist, in ihrem Wasservolumenstrom derart zu bemessen, dass in Kombination der beiden Sprühwasserdüsen ein Unterdruck im Dampfkondensator nach wie vor sichergestellt ist. Durch diese Mehrstufigkeit der Kondensationswirkung kann im Ergebnis der Wasserverbrauch reduziert, das heißt Verbrauchswasser eingespart werden.According to a further feature of the invention it is provided that the steam condenser has a second spray water nozzle. It is preferred that the first and second Sprühwasserdüse are aligned with respect to the flow direction of the guided through the steam condenser volume flow opposite to each other. In this way, an optimized cooling and thus condensation of the guided through the steam condenser steam can be achieved. In this case, the second spray nozzle, which is aligned in the counterflow direction to the first Sprühwasserdüse, to be dimensioned in their water volume flow such that a vacuum in the steam condenser is still ensured in combination of the two Sprühwasserdüsen. As a result of this multistage effect of condensation, water consumption can be reduced, that is, consumption water can be saved.

Verfahrensseitig wird zur Lösung der eingangs genannten Art vorgeschlagen ein Verfahren zum Betrieb eines mit einem Dampfkondensator und einem Trocknungsgebläse ausgerüsteten Geschirrspülautomatens während einer Trocknungsphase, bei dem mit Beginn der Trocknungsphase das Trocknungsgebläse eingeschaltet und in einer ersten Schaltstufe mit einem geförderten Volumenstrom von 7 bis 10 m3/h betrieben wird, bei dem gleichzeitig eine Sprühwasserdüse des Dampfkondensators mit einem Wasservolumenstrom beschickt wird, der auf den Volumenstrom des Trocknungsgebläses abgestimmt wird, so dass im Spülraum des Geschirrspülautomaten ein Unterdruck ausgebildet wird.In terms of the method, a method for operating a dishwasher equipped with a steam condenser and a drying blower during a drying phase is proposed in which the drying blower is switched on at the beginning of the drying phase and in a first switching stage with a delivered volume flow of 7 to 10 m 3 / h is operated, in which at the same time a Sprühwasserdüse the steam condenser is charged with a flow of water volume, which is tuned to the flow rate of the drying fan, so that in the washing compartment of the dishwasher a negative pressure is formed.

Nach der erfindungsgemäßen Verfahrensdurchführung wird das Trocknungsgebläse im Unterschied zum Stand der Technik bereits mit Beginn der Trocknungsphase zum Zwecke der Unterstützung der Dampfkondensation eingeschaltet. Dabei wird mit Beginn der Trocknungsphase das Trocknungsgebläse nur mit einem verhältnismäßig geringen Volumenstrom von 7 bis 10 m3/h betrieben. Es erfolgt insofern eine Art "Sanftanlauf" des Trocknungsgebläses. Durch die Unterstützung des Trocknungsgebläses wird in vorteilhafter Weise eine sehr viel schnellere Dampfkondensation bewirkt, so dass sich im Ergebnis eine verkürzte Gesamtbehandlungsdauer einstellt. Sobald der Dampf aus dem Spülraum entfernt und im Dampfkondensator auskondensiert ist, kann das Trocknungsgebläse in eine höhere Schaltstufe umgeschaltet werden, der gemäß es mit einem in der Fördermenge gesteigerten Volumenstrom betrieben wird. Es kann beispielsweise ein Volumenstrom von 75 m3/h vorgesehen sein.After carrying out the method according to the invention, in contrast to the prior art, the drying fan is already switched on at the beginning of the drying phase for the purpose of supporting the steam condensation. The drying fan is operated at the beginning of the drying phase only with a relatively low volume flow of 7 to 10 m 3 / h. It is insofar a kind of "soft start" of the drying blower. By supporting the drying blower, a much faster steam condensation is advantageously effected, so that the result is a shortened overall treatment time. As soon as the steam has been removed from the washing compartment and condensed out in the steam condenser, the drying fan can be switched over to a higher switching stage, which according to the invention is operated with an increased flow rate in the flow rate. For example, a volume flow of 75 m 3 / h may be provided.

Während der Anlaufphase wird im Spülraum ein Unterdruck eingestellt, beispielsweise ein Unterdruck von - 0,1 mbar gegenüber dem Normaldruck. Es wird so sichergestellt, dass der in der Anlaufphase im Geschirrspülautomaten noch befindliche Dampf nicht durch irgendwelche Undichtigkeiten für den Anwender sichtbar nach außen dringen kann.During the start-up phase, a negative pressure is set in the washing compartment, for example a negative pressure of -0.1 mbar in relation to the normal pressure. It is thus ensured that the vapor still present in the automatic dishwasher during the start-up phase can not visibly penetrate to the outside due to any leaks to the user.

Gemäß einem weiteren Merkmal der Erfindung ist vorgesehen, dass ein Bypass zwischen dem Dampfkondensator und einem den Spülraum bereitstellenden Spülbehälter druckabhängig geöffnet beziehungsweise geschlossen wird. Hierdurch wird eine Verminderung des sich im Volllastbetrieb des Trocknungsgebläses im Dampfkondensator einstellenden Gegendrucks erzielt, was die schon vorstehend beschriebenen Vorteile erbringt.According to a further feature of the invention, it is provided that a bypass between the steam condenser and a washing container providing the washing compartment is opened or closed depending on the pressure. This achieves a reduction of the counter pressure occurring in the steam condenser during full-load operation of the drying fan, which yields the advantages already described above.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung anhand der Figuren. Dabei zeigt

Further features and advantages of the invention will become apparent from the following description with reference to FIGS. It shows
FIG. 1
in a schematic representation of a dishwasher according to the invention and
FIG. 2
a schematic representation of a steam condenser with an optional bypass.

Figur 1 lässt in schematischer Darstellung einen Geschirrspülautomaten 12 erkennen. Der Geschirrspülautomat 12 verfügt über einen Spülbehälter 13, der einen Spülraum 14 bereitstellt. Im bestimmungsgemäßen Verwendungsfall des Geschirrspülautomatens 12 dient der Spülraum 14 der Aufnahme von zu reinigendem Spülgut. FIG. 1 can be seen in a schematic representation of a dishwasher 12. The automatic dishwashing machine 12 has a washing container 13, which provides a washing compartment 14. In the intended use case of the dishwasher 12, the washing compartment 14 serves to receive items to be cleaned.

Der Geschirrspülautomat 12 verfügt des Weiteren über einen Seitenschrank 11. Dieser Seitenschrank 11 nimmt ein Trocknungsgebläse 10 auf. Über einen Kanal 9 steht das Trocknungsgebläse 10 mit dem vom Spülbehälter 13 bereitgestellten Spülraum 14 in strömungstechnischer Verbindung. Dabei strömt der vom Trocknungsgebläse 10 geförderte Volumenstrom in Richtung des Pfeils 18 und gelangt über die Eintrittsöffnung 8 in den Spülraum 14.The dishwasher 12 further has a side cabinet 11. This side cabinet 11 receives a drying fan 10. Via a channel 9 is the drying fan 10 with the washing compartment 13 provided by the washing compartment 14 in fluid communication. In this case, the volume flow conveyed by the drying fan 10 flows in the direction of the arrow 18 and passes via the inlet opening 8 into the washing compartment 14.

Der Geschirrspülautomat 12 weist ferner einen Dampfkondensator 1 auf. Der Dampfkondensator 1 steht mit dem Spülraum 14 des Spülbehälters 13 ebenfalls in strömungstechnischer Verbindung, wobei der Dampfkondensator 1 eine Eintrittsöffnung 4 und eine Austrittsöffnung 3 aufweist. Dabei gelangt über die Eintrittsöffnung 4 ein aus dem Spülraum 14 stammender Volumenstrom in den Dampfkondensator 1. In Entsprechung des Pfeils 17 wird der Dampfkondensator 1 durchströmt, wobei der durch den Dampfkondensator 1 hindurchgeführte Volumenstrom die vom Dampfkondensator 1 bereitgestellte Labyrinthführung 16 passiert. Nach einem Durchströmen des Dampfkondensators 1 gelangt der durch den Dampfkondensator 1 hindurchgeführte Volumenstrom über die Austrittsöffnung 3 zurück in den Spülraum 14.The dishwasher 12 also has a steam condenser 1. The steam condenser 1 is also in fluid communication with the washing compartment 14 of the washing compartment 13, the steam condenser 1 having an inlet opening 4 and an outlet opening 3. In this case, via the inlet opening 4, a volumetric flow originating from the washing compartment 14 into the steam condenser 1. In correspondence of the arrow 17, the steam condenser 1 is flowed through, wherein the volume flow passed through the steam condenser 1 passes through the labyrinth guide 16 provided by the steam condenser 1. After flowing through the steam condenser 1, the volume flow passed through the steam condenser 1 returns via the outlet opening 3 back into the washing compartment 14.

Der Dampfkondensator 1 verfügt über eine erste Sprühwasserdüse 2 sowie über eine zweite Sprühwasserdüse 15. In Durchströmungsrichtung in Entsprechung des Pfeils 17 sind die Sprühwasserdüsen 2 und 15 einander gegenüberliegend ausgerichtet. Die erste Sprühwasserdüse 2 gibt den von ihr geförderten Wasservolumenstrom in Strömungsrichtung des den Dampfkondensator 1 durchströmenden Volumenstroms ab. Die zweite Sprühwasserdüse 15 ist indes im Gegenstrom zur Strömungsrichtung des den Dampfkondensator 1 durchströmenden Volumenstroms ausgerichtet.The steam condenser 1 has a first spray water nozzle 2 and a second spray water nozzle 15. In the flow direction in correspondence of the arrow 17, the spray water nozzles 2 and 15 are aligned opposite each other. The first spray water nozzle 2 discharges the water volume flow conveyed by it in the direction of flow of the volume flow flowing through the steam condenser 1. The second Sprühwasserdüse 15 is, however, aligned in countercurrent to the flow direction of the steam condenser 1 flowing through the flow rate.

Im Betriebsfall werden die Sprühwasserdüsen 2 und 15 des Dampfkondensators 1 mit unterschiedlichen Wasservolumenströmen betrieben. Dabei ist der Wasservolumenstrom der ersten Sprühwasserdüse 2 deutlich höher als der Wasservolumenstrom der zweiten Sprühdüse 15, beispielsweise um einen Faktor von 3 bis 4. Die erste Sprühwasserdüse 2 bewirkt aufgrund ihrer Ausrichtung in Richtung des Strömungswegs eines durch den Dampfkondensator 1 hindurchgeführten Volumenstroms einen Unterdruck im Spülraum 14. Aufgrund ihrer umgekehrten Ausrichtung bewirkt die zweite Sprühdüse 15 indes eine Überdruckausbildung. Durch das entsprechende Verhältnis der Wasservolumenströme, das über die beiden Sprühwasserdüsen 2 und 15 abgegeben wird, wird sichergestellt, dass sich in Summe der durch die beiden Sprühwasserdüsen 2 und 15 bewirkten Drücke ein Unterdruck im Spülraum 14 einstellt, beispielsweise ein Unterdruck von - 0,3 mbar gegenüber Normaldruck.In operation, the spray nozzles 2 and 15 of the steam condenser 1 are operated with different water flow rates. In this case, the water volume flow of the first spray nozzle 2 is significantly higher than the water volume flow of the second spray nozzle 15, for example by a factor of 3 to 4. The first spray nozzle 2 causes due to their orientation in the direction of the flow path of a volume flow passed through the steam condenser 1, a negative pressure in the washing compartment 14. Due to its reverse orientation causes the second spray nozzle 15, however, a positive pressure education. By the corresponding ratio of the water volume flows, which is discharged via the two Sprühwasserdüsen 2 and 15, it is ensured that a total of the pressures caused by the two Sprühwasserdüsen 2 and 15, a negative pressure in the washing compartment 14, for example, a negative pressure of - 0.3 mbar compared to normal pressure.

Erfindungsgemäß ist vorgesehen, dass mit Beginn der Trocknungsphase, wenn es also noch gilt, im Spülraum 14 befindlichen Dampf abzusaugen und im Dampfkondensator 1 zu kondensieren, das Trocknungsgebläse 10 bereits anläuft. Hierdurch bedingt kann ein schnellerer Austrag des Dampfes aus dem Spülraum 14 bewirkt werden. Infolge eines Betriebs des Trocknungsgebläses 10 kommt es aber zu einer Überdruckausbildung, was es zu vermeiden gilt, damit nicht über etwaige Undichtigkeiten ungewollt Dampf nach außen dringen kann. Aus diesem Grunde ist vorgesehen, dass der vom Trocknungsgebläse 10 geförderte Volumenstrom auf den Wasservolumenstrom der Sprühwasserdüsen 2 und 15 derart abgestimmt ist, dass im Spülraum 14 im Ergebnis ein Unterdruck ausgebildet ist. Bevorzugterweise ist in diesem Zusammenhang vorgesehen, dass der durch das Trocknungsgebläse 10 geförderte Volumenstrom einem Überdruck im Spülraum von ca. 2/3 des Betrages des Unterdrucks des Dampfkondensators 1 entspricht. Dadurch bleibt in Summe ein Unterdruck im Spülraum 14 bestehen. Wird also beispielsweise im gezeigten Ausführungsbeispiel durch die beiden Sprühdüsen 2 und 15 in Summe ein Unterdruck von - 0,3 mbar gegenüber Normal erreicht, so ist für das Trocknungsgebläse 10 ein solcher Volumenstrom zulässig, der im Spülraum 14 zu einem Überdruck von 0,2 mbar gegenüber Normal führen würde. Im Ergebnis stellt sich ein Gesamtdruck von - 0,1 mbar gegenüber Normal im Spülraum 14 ein. Dies reicht aus, dass kein Dampf ungewollt über die Türdichtung entweicht. Gleichzeitig wird deutlich schneller als bei reinem Saugbetrieb des Dampfkondensators 1 der Dampf aus dem Spülraum 14 abgefördert.According to the invention, it is provided that, at the beginning of the drying phase, if it still applies, to suck vapor present in the washing chamber 14 and to condense it in the steam condenser 1, the drying fan 10 already starts. As a result, a faster discharge of the steam from the washing compartment 14 can be effected. As a result of an operation of the drying blower 10 but it comes to a positive pressure training, which should be avoided so that can not accidentally penetrate any leaks of steam to the outside. For this reason, it is provided that the volume flow delivered by the drying fan 10 is matched to the water volume flow of the spray water nozzles 2 and 15 such that a negative pressure is formed in the washing chamber 14 as a result. Preferably, it is provided in this context that the volume flow delivered by the drying fan 10 is subject to overpressure in the Flushing of about 2/3 of the amount of negative pressure of the steam condenser 1 corresponds. As a result, a negative pressure in the washing compartment 14 remains in total. If, for example, in the embodiment shown by the two spray nozzles 2 and 15 in total a negative pressure of - 0.3 mbar compared to normal, so is for the drying fan 10 such a flow rate permissible in the washing chamber 14 to an overpressure of 0.2 mbar would lead to normal. As a result, a total pressure of -0.1 mbar compared to normal in the washing compartment 14 sets. This is sufficient that no steam escapes unintentionally via the door seal. At the same time, the steam is carried away from the washing chamber 14 much faster than in the case of pure suction operation of the steam condenser 1.

So war bei Geschirrspülautomaten 12 nach dem Stand der Technik bislang ein Betrieb von 6 Minuten notwendig, um den im Spülraum 14 befindlichen Dampf aus dem Spülraum 14 vollständig mit Hilfe der Sprühwasserdüse 2 des Dampfkondensators 1 abzusaugen. Mit Hilfe der erfindungsgemäßen Gebläseunterstützung ist es möglich, diese Zeit auf 2 Minuten zu verkürzen. Diese Zeitverkürzung führt ebenfalls dazu, dass die Ansteuerzeit der Sprühwasserdüsen 2 bzw. 15 sinkt, womit es zu einer deutlichen Wassereinsparung kommt.Thus, in the case of dishwashers 12 according to the state of the art, an operation of 6 minutes has hitherto been necessary in order to completely suck off the steam in the washing compartment 14 from the washing compartment 14 with the aid of the spray nozzle 2 of the steam condenser 1. With the help of the fan support according to the invention, it is possible to shorten this time to 2 minutes. This reduction in time also leads to the activation time of the spray water nozzles 2 and 15 decreasing, resulting in a significant saving of water.

Gemäß einer vorteilhaften Ausgestaltung kann im Übrigen vorgesehen sein, dass mit Hilfe eines Drucksensors eine Regelstrecke aufgebaut wird. Der Drucksensor ist im Spülraum 14 angebracht und misst den Spülrauminnendruck. Der Volumenstrom des Trocknungsgebläses 10 wird solange erhöht, bis sich am Drucksensor ein Sollwert einstellt. Dieser Druckwert wird durch die Regelstrecke konstant gehalten. Hierdurch ist sichergestellt, dass immer der maximal mögliche Volumenstrom vom Trocknungsgebläse 10 gefördert wird und jederzeit ein Unterdruck im Spülraum 14 herrscht.According to an advantageous embodiment, it may be provided, moreover, that a controlled system is built up with the aid of a pressure sensor. The pressure sensor is mounted in the washing compartment 14 and measures the Spülrauminnendruck. The volume flow of the drying fan 10 is increased until a setpoint value is set at the pressure sensor. This pressure value is kept constant by the control system. This ensures that the maximum possible volume flow is always conveyed by the drying fan 10 and there is always a negative pressure in the washing compartment 14.

Eine optionale Ausgestaltung des Dampfkondensators 1 ist in Figur 2 dargestellt.An optional embodiment of the steam condenser 1 is in FIG. 2 shown.

Figur 2 lässt in schematischer Darstellung einen Dampfkondensator 1 erkennen, der im Wesentlichen demjenigen nach Figur 1 entspricht. Der in Figur 2 gezeigte Dampfkondensator 1 verfügt im Unterschied zum vorbeschriebenen Dampfkondensator 1 indes nur eine Sprühwasserdüse 2. FIG. 2 can be seen in a schematic representation of a steam condenser 1, which is essentially after that FIG. 1 equivalent. The in FIG. 2 shown steam condenser 1 has, in contrast to the above-described steam condenser 1, however, only one spray nozzle. 2

Ferner verfügt der Dampfkondensator 1 nach Figur 2 über einen Bypass 19, der der Austrittsöffnung 7 für kondensiertes Wasser gegenüberliegend ausgebildet ist. Der Bypass 19 dient der Hindurchführung eines über die Eintrittsöffnung 4 in den Dampfkondensator 1 eingeleiteten Volumenstroms, das heißt einer Rückführung des Volumenstroms zurück in den Spülraum 14 unter Auslassung der Labyrinthführung 16 des Dampfkondensators 1. Der Bypass 19 stellt eine Öffnung 20 bereit. Diese Öffnung ist mittels einer Bypassklappe 6 verschließbar. Diese Bypassklappe 6 wird von Zugfedern 5 gehalten, die im Normalzustand ein Verschließen der Öffnung 20 durch die Bypassklappe 6 bewirken. Dabei sind die Zugfedern 5 derart ausgelegt, dass bei Erreichen eines bestimmten Überdrucks im Dampfkondensator 1 ein Öffnen der Bypassklappe 6 erfolgt, so dass ein Überströmen eines über die Eintrittsöffnung 4 in den Dampfkondensator 1 eingelassenen Volumenstrom über die Öffnung 20 direkt zurück in den Spülraum 14 stattfinden kann. In der Konsequenz wird der Strömungsweg auf diese Weise verkürzt, und es kann zu einem Abbau des Überdrucks im Dampfkondensator 1 kommen, bis eine solche Druckreduzierung eingetreten ist, dass durch die Zugfedern 5 bewirkt ein automatisches druckabhängiges Schließen der Öffnung 20 des Bypasses 19 durch die Bypassklappe 6 erfolgt.Furthermore, the steam condenser 1 has after FIG. 2 via a bypass 19, which is formed opposite to the outlet opening 7 for condensed water. The bypass 19 serves to pass a volume flow introduced via the inlet opening 4 into the steam condenser 1, that is to say a return of the volume flow back into the washing compartment 14 omitting the labyrinth guide 16 of the steam condenser 1. The bypass 19 provides an opening 20 ready. This opening can be closed by means of a bypass flap 6. This bypass flap 6 is held by tension springs 5, which cause a closure of the opening 20 through the bypass flap 6 in the normal state. In this case, the tension springs 5 are designed such that upon reaching a certain overpressure in the steam condenser 1 opening of the bypass valve 6 takes place, so that an overflow of a recessed into the steam condenser 1 via the inlet 4 volume flow via the opening 20 take place directly back into the washing compartment 14 can. As a consequence, the flow path is shortened in this way, and it can lead to a reduction of the overpressure in the steam condenser 1, until such a pressure reduction has occurred that caused by the tension springs 5, an automatic pressure-dependent closing of the opening 20 of the bypass 19 through the bypass valve 6 takes place.

Der Vorteil dieser optionalen Ausgestaltung des Bypasses 19 liegt darin, dass der Strömungsweg für den Volumenstrom, d. h. die Trocknungsluft verkürzt ist, womit Druckverluste deutlich reduziert werden können.The advantage of this optional embodiment of the bypass 19 is that the flow path for the volume flow, d. H. the drying air is shortened, whereby pressure losses can be significantly reduced.

Bei aus dem Stand der Technik vorbekannten Dampfkondensatoren 1 wird die vom Trocknungsgebläse 10 geförderte Trocknungsluft komplett durch den Dampfkondensator 1 hindurchgeführt. Dies erzeugt einen hohen Gegendruck, da der Dampfkondensator 1 strömungstechnisch für das Auskondensieren von Dampf und nicht für das Hindurchführen von Trocknungsluft optimiert ausgelegt ist. Die erfindungsgemäße Ausgestaltung gestattet es, bei einem Betrieb des Trocknungsgebläses 10 den Bypass 19 zu öffnen, wodurch Druckverluste sehr stark verringert werden, da nicht mehr der komplette Strömungsweg des Dampfkondensators 1 von der Trocknungsluft durchströmt werden muss. Dabei liegt die Öffnung 20 des Bypasses 19 idealerweise sehr nahe an der Eintrittsöffnung 4 für den Dampfkondensator 1.In previously known from the prior art steam condensers 1, the drying air conveyed by the drying fan 10 is completely passed through the steam condenser 1. This produces a high back pressure, since the steam condenser 1 is designed to be optimized in terms of flow for the condensation of steam and not for the passage of drying air. The embodiment according to the invention makes it possible to open the bypass 19 during operation of the drying fan 10, as a result of which pressure losses are greatly reduced since it is no longer necessary for the drying air to flow through the complete flow path of the steam condenser 1. The opening 20 of the bypass 19 is ideally located very close to the inlet opening 4 for the steam condenser. 1

Die Bypassöffnung 20 öffnet sich entweder aufgrund des steigenden Innendrucks bei Betrieb des Trocknungsgebläses 10 oder durch einen in den Figuren nicht näher dargestellten Aktor, der durch die Steuerung des Geschirrspülautomaten 12 angesteuert ist.The bypass opening 20 opens either due to the increasing internal pressure during operation of the drying fan 10 or by an actuator not shown in detail in the figures, which is controlled by the control of the dishwasher 12.
