Description

Die Erfindung betrifft ein Verfahren zum Betreiben eines wasserführenden Haushaltsgeräts, insbesondere einer Geschirrspülmaschine, das eine Umwälzpumpe und eine der Umwälzpumpe zugeordnete, insbesondere der Umwälzpumpe nachgeschaltete, Wasserweiche mit mindestens einem durch einen Stellelementmotor verstellbares Stellelement zur Richtungsänderung einer Flüssigkeitsströmung durch die Wasserweiche aufweist, bei dem das wasserführende Haushaltsgerät mit einer mit der Umwälzpumpe umwälzbaren Mindestfüllwassermenge befüllt wird und in einem ersten Schritt überprüft wird, ob eine Fehlfunktion der Wasserweiche vorliegt, und in einem zweiten Schritt durch eine Rundlaufprüfung überprüft wird, ob die Größe der Mindestfüllwassermenge im wasserführenden Haushaltsgerät wenigstens der Größe einer Sollfüllwassermenge zum Gewährleisten des Rundlaufs der Umwälzpumpe entspricht, wobei zur Rundlaufprüfung wenigstens ein Betriebsparameter eines die Umwälzpumpe antreibenden Elektromotors auf einen Rundlauf der Umwälzpumpe hin ausgewertet wird.The invention relates to a method for operating a water-conducting household appliance, in particular a dishwasher, which has a circulation pump and one of the circulating pump associated, in particular the circulation downstream water diverter with at least one adjustable by an actuator motor actuator for changing direction of a liquid flow through the water diverter, wherein the water-bearing household appliance is filled with a circulating with the circulation pump Mindestfüllwassermenge and is checked in a first step, if a malfunction of the water gate is present, and checked in a second step by a concentricity test, if the size of the Mindestfüllwassermenge in water-bearing household appliance at least the size of a Sollfüllwassermenge to ensure the concentricity of the circulating pump, wherein for concentricity testing at least one operating parameter of the circulating pump driving Electric motor is evaluated on a concentricity of the circulation pump out.

Wasserführenden Haushaltsgeräten wird über einen entsprechenden Anschluss Wasser zugeführt, das in dem Haushaltsgerät mit Spül- oder Waschmittel und gegebenenfalls weiteren Mitteln versetzt und in einen Arbeitsraum gefördert wird, in welchem sich zu reinigendes Gut, wie beispielsweise Geschirr (Spülmaschine) oder Kleidungsstücke (Waschmaschine) befindet. Um den Wasserverbrauch gering zu halten, wird während des Spülvorgangs die in den Arbeitsraum eingebrachte Flüssigkeit gesammelt und anschließend wieder in den Arbeitsraum gefördert. Hierfür sind Umwälzpumpen vorgesehen. Bei bekannten Haushaltsgeräten ist der Umwälzpumpe eine Wasserweiche zugeordnet, insbesondere in Strömungsrichtung nachgeschaltet, die dazu dient, Flüssigkeitsströme einzustellen beziehungsweise in eine gewünschte Richtung zu lenken. Im Falle eines Einsatzes in einer Waschmaschine dienen Wasserweichen beispielsweise dazu, Wasch- oder Spülwasser beispielsweise in eine erste oder an eine zweite Spülkammer von zwei Spülkammern zu lenken. Im Falle des Einsatzes in Geschirrspülmaschinen dienen Wasserweichen beispielsweise dazu, Spülwasserströme, auch Spülflotten genannt, beispielsweise zu einem Sprüharm für einen Oberkorb und/oder zu einem Sprüharm für einen Unterkorb zuzuleiten. Hierzu weisen die Wasserweichen mindestens ein motorisch bewegbares Stellelement auf, mittels dessen unterschiedliche Durchströmungsöffnungen der Wasserweiche auf entsprechende Ansteuersignale hin durch das Stellelement geöffnet und/oder verschlossen werden können, um die gewünschte Aufteilung der Flüssigkeitsströme einzustellen. Dabei durchlaufen wasserführende Haushaltsgeräte wie z.B. Geschirrspülmaschinen Spülprogramme, die mehrere Spülprogrammschritte umfassen, die jeweils mit einer Befüllung der Geschirrspülmaschine mit einer Mindestspülwassermenge beginnen und mit einem Abpumpvorgang enden, um die nun verschmutzte Spülwassermenge aus der Geschirrspülmaschine zu fördern. Wenn die umgewälzte Spülwassermenge geringer als eine für den zuverlässigen Betrieb notwendige Menge ist, bspw. weil sich in einem mit seiner nach oben gerichteten Glas oder Topf Spülwasser sammelt und mit mehr umgewälzt werden kann, kann die Folge eine unangenehme Geräuschentwicklung aufgrund einer Luft ansaugenden Pumpe sein oder das Reinigungs- und Trocknungsergebnis ist nicht zufriedenstellend. Ein Verfahren gemäss dem Oberbegriff des Anspruchs 1 ist aus EP 1 967 121 A1 benannt. Es ist daher die Aufgabe der Erfindung, hier Abhilfe zu schaffen.Water-conducting household appliances is supplied via a corresponding connection water, which is added in the household appliance with detergent or detergent and optionally other agents and conveyed into a working space in which to be cleaned Good, such as dishes (dishwasher) or garments (washing machine) , In order to keep the water consumption low, the liquid introduced into the working space is collected during the rinsing process and then conveyed back into the working space. For this purpose circulating pumps are provided. In known household appliances, the circulating pump is associated with a water separator, in particular downstream in the flow direction, which serves to set liquid flows or to direct them in a desired direction. In the case of use in a washing machine, for example, water switches serve to direct washing or rinsing water, for example, into a first or a second rinsing chamber of two rinsing chambers. In the case of use in dishwashers, for example, water softeners serve to feed flushing water streams, also called flushing liquors, for example to a spray arm for a top basket and / or to a spray arm for a lower basket. For this purpose, the water points on at least one motor-movable actuator, by means of which different flow openings the water diverter can be opened and / or closed by the adjusting element in response to appropriate control signals in order to set the desired distribution of the liquid flows. In this case, water-conducting household appliances such as dishwashers go through wash programs that include several wash program steps that each begin with a filling of the dishwasher with a minimum amount of flushing and end with a pumpdown to promote the now polluted amount of flushing water from the dishwasher. When the circulated flushing water amount is less than a necessary amount for reliable operation, for example, because rinsing water collects in one with its glass or pot pointing upwards and can be circulated with more, the result may be an unpleasant noise due to an air sucking pump or the cleaning and drying result is not satisfactory. A method according to the preamble of claim 1 is made EP 1 967 121 A1 named. It is therefore the object of the invention to remedy this situation.

Erfindungsgemäß ist vorgesehen, dass eine Rundlaufprüfung oder ein Nachfüllschritt zum Erhöhen der Mindestfüllwassermenge durchgeführt wird, wenn keine Fehlfunktion der Wasserweiche vorliegt und die Rundlaufprüfung oder der Nachfüllschritt ausgeblendet wird, wenn eine Fehlfunktion der Wasserweiche festgestellt wird. Wenn eine Fehlfunktion der Wasserweiche vorliegt kann dies z.B. zur Folge haben, dass die Rundlaufprüfung fälschlicherweise zu dem Ergebnis führen kann, dass z.B. ein Trockenlauf der Umwälzpumpe vorliegt, worauf dann ein Nachfüllvorgang zur Erhöhung der umgewälzten Flüssigkeitsmenge erfolgen kann mit der Folge, dass das wasserführende Haushaltsgerät überfüllt wird und Wasser aus dem wasserführenden Haushaltsgerät austritt. Erst wenn festgestellt ist, dass die Wasserweiche bestimmungsgemäß funktioniert erfolgt eine Rundlaufprüfung mit Ziel festzustellen, ob wenigstens die Sollfüllwassermenge in dem wasserführenden Haushaltsgerät umwälzbar ist. Dabei kann zur Durchführung der Rundlaufprüfung als ein Betriebsparameter z.B. die Stromaufnahme des die Umwälzpumpe antreibenden Motors auf Schwankungen überwacht werden, die durch das Luftansaugen der Umwälzpumpe bei zu niedrigem Füllstand hervorgerufen werden. Wenn jedoch die Überprüfung der Funktion der Wasserweiche ergibt, dass diese nicht bestimmungsgemäß funktioniert, wird erfolgt keine Rundlaufprüfung. Ferner kann auch ein Nachfüllschritt ausgeblendet werden, mit dem die Füllwassermenge bei funktionsfähiger Wasserweiche erhöht werden kann, so dass eine Überfüllung mit einem Wasseraustritt aus dem wasserführenden Haushaltsgerät verhindert ist. Dabei kann das Befüllen des Haushaltsgeräts mit einer Mindestfüllwassermenge vor, nach oder auch während des ersten Schritts zur Funktionsüberprüfung der Wasserweiche erfolgen, oder vor dem zweiten Schritt, bei dem eine Rundlaufprüfung durchgeführt wird.According to the invention, it is provided that a concentricity test or a refilling step for increasing the minimum filling water quantity is carried out if there is no malfunction of the water distributor and the concentricity test or the refilling step is faded out if a malfunction of the water distributor is detected. If a malfunction of the water switch is present, this can have the consequence, for example, that the concentricity test can lead to the result that, for example, there is dry running of the circulating pump, whereupon a refilling process can be carried out to increase the volume of liquid circulated, with the result that the water-conducting domestic appliance is overfilled and water comes out of the water-bearing household appliance. Only when it has been determined that the water diverter works as intended is a concentricity test to be carried out with the aim of determining whether at least the nominal filling water quantity in the water-bearing domestic appliance can be recirculated. In this case, for carrying out the concentricity test as an operating parameter, for example, the current consumption of the motor driving the circulation pump can be monitored for fluctuations caused by the air intake of the circulation pump when the level is too low. However, if the verification of the function of the water separator shows that it does not function as intended, there will be no concentricity test. Furthermore, a refilling step can be hidden, with which the filling water amount can be increased with functional water switch, so that overfilling with a water outlet from the water-bearing Household appliance is prevented. In this case, the filling of the household appliance with a Mindestfüllwassermenge before, after or during the first step to check the function of the water diverter, or before the second step, in which a concentricity test is performed.

Dabei ist vorzugsweise vorgesehen, dass zum Überprüfen, ob eine Fehlfunktion der vorliegt, Ansteuersignale zum Ansteuern des Stellelementmotors und Sensorsignale von wenigstens einem Sensor zur Positionserfassung des Stellelements der Wasserweiche ausgewertet werden. Mit dem Sensor zur Positionserfassung ist es möglich, das Stellelement der Wasserweiche zu Beginn eines Spülprogramm oder während einzelner Schritte durch Aktivieren des Stellelementmotors in eine definierte Position zu bringen, da sich das Stellelement z.B. aufgrund eines Stromausfalls in einer nicht definierten Position befinden kann. Somit kann auf eine funktionsfähige Wasserweiche geschlossen werden, wenn auf das Ansteuern des Stellelementmotors innerhalb einer gewissen Zeitdauer ein Sensorsignal erfasst wird.It is preferably provided that for checking whether a malfunction is present, control signals for driving the actuator motor and sensor signals from at least one sensor for position detection of the control element of the water gate are evaluated. With the sensor for position detection, it is possible to bring the control element of the water switch at the beginning of a wash program or during individual steps by activating the actuator motor in a defined position, as the actuator, e.g. due to a power failure in an undefined position. Thus, it can be concluded that there is a functioning water distributor if a sensor signal is detected within a certain period of time on the actuation of the actuator motor.

Hingegen wird vorzugsweise auf eine Fehlfunktion der Wasserweiche geschlossen, wenn die Sensorsignale abweichend von den Ansteuersignalen einem stillstehenden oder einem sich in einer unterbrechungsfreien Dauerbewegung befindlichen Stellelement entsprechen oder die Sensorsignale von einem erwarteten Sensorsignalverlauf oder Sensorsignalfolge abweichen. Somit kann zum einen z.B. ein Defekt des Stellelementmotors erfasst werden, der zur Folge hat, dass das Stellelement stillsteht. Eine unterbrechungsfreie Dauerbewegung des Stellelements hingegen kann z.B. Folge eines defekten Sensors sein, sodass keine definierte Stoppposition für das Stellelement erfasst wird. Schließlich können Abweichungen von einem erwarteten Sensorsignalverlauf oder -folge ihre Ursache in defekten Signalleitungen des Sensors oder in einer Fehlfunktion des Sensors selbst haben.On the other hand, it is preferable to conclude that the waterway is malfunctioning if the sensor signals deviate from the control signals correspond to a stationary control element or to an actuating element that is in continuous uninterrupted motion or if the sensor signals deviate from an expected sensor signal sequence or sensor signal sequence. Thus, for example, a defect of the actuator motor can be detected, which has the consequence that the actuator is stationary. An uninterrupted continuous movement of the actuating element, however, can e.g. Result of a defective sensor so that no defined stop position is detected for the actuator. Finally, deviations from an expected sensor waveform or sequence may be due to defective signal lines of the sensor or to a malfunction of the sensor itself.

In einer bevorzugten Weiterbildung ist vorgesehen, dass auf Erfassen einer Dauerbewegung des Stellelements der Wasserweiche der Stellelementmotor gestoppt wird. Durch Abschalten beziehungsweise Ausschalten der Wasserweiche wird gewährleistet, dass die Flüssigkeit zwar weiterhin umgewälzt werden kann, wenn auch nur in einer durch das nun stillstehende Stellelement bestimmten Verteilung. Somit kann z.B. ein Spülprogramm fortgesetzt werden.In a preferred embodiment, it is provided that the actuating element motor is stopped upon detecting a continuous movement of the actuating element of the water switch. By switching off or switching off the water switch ensures that the liquid can still be circulated, albeit only in a certain by the now stationary actuator distribution. Thus, for example, a washing program can be continued.

In einer weiteren, bevorzugten Weiterbildung ist vorgesehen, dass bei ausgeblendeter Rundlaufprüfung die Mindestfüllwassermenge beibehalten wird. Da bei ausgeblendeter Rundlaufprüfung keine Aussage z.B. über den Trockenlauf der Umwälzpumpe getroffen werden kann, wird bevorzugt die Mindestfüllwassermenge dann beibehalten, wenn das laufende Betriebsprogramm des Haushaltsgeräts einen Punkt erreicht hat, bei dem davon auszugehen ist, dass bereits ausreichend Flüssigkeit zugeführt wurde.In a further, preferred development, it is provided that, when the concentricity test is hidden, the minimum amount of filling water is maintained. Since, with hidden concentricity check, no statement, e.g. can be made on the dry running of the circulating pump, the Mindestfüllwassermenge is preferably maintained when the current operating program of the household appliance has reached a point at which it can be assumed that already sufficient liquid has been supplied.

Ferner ist vorzugsweise vorgesehen, dass bei ausgeblendeter Rundlaufprüfung eine Mindestsollfüllwassermenge oder eine Maximalsollfüllwassermenge eingestellt wird. Besonders bevorzugt wird bei ausgeblendeter Rundlaufprüfung eine Mindestsollfüllwassermenge eingestellt. Die Mindestsollfüllwassermenge ergibt sich vorteilhafterweise aus bekannten Werten, die einen Nasslauf der Umwälzpumpe gewährleisten beziehungsweise einen Trockenlauf bei normaler Belastung beziehungsweise bei einer normalen/durchschnittlichen Spülgutmenge verhindern. Alternativ zu der Mindestfüllsollwassermenge wird bei ausgeblendeter Rundlaufprüfung eine Maximalsollfüllwassermenge eingestellt. Die Maximalsollfüllwassermenge gewährleistet zum einen den Nasslauf der Umwälzpumpe und zum anderen eine ausreichende Füllwassermenge zur Reinigung allen Spülguts, insbesondere auch bei einer maximalen Belastung der Haushaltsmaschine. Ob die Mindestsollfüllwassermenge oder die Maximalsollfüllwassermenge eingestellt wird, kann beispielsweise in Abhängigkeit von dem durch den Benutzer gewählten Spülprogramm bestimmt werden.Furthermore, it is preferably provided that, with the concentricity test hidden, a minimum nominal filling water quantity or a maximum nominal filling water quantity is set. It is particularly preferred to set a minimum nominal filling water volume when the concentricity test is blanked out. The Mindestestsollfüllwassermenge results advantageously from known values that ensure a wet run of the circulation pump or prevent dry running at normal load or at a normal / average Spülgutmenge. As an alternative to the minimum refill water quantity, a maximum refill water quantity is set when the concentricity test is hidden. The Maximum Sollfüllwassermenge ensures on the one hand the wet running of the circulation pump and on the other hand a sufficient amount of filling water for cleaning all items to be washed, especially at a maximum load on the appliance. For example, it may be determined depending on the rinse program selected by the user whether the minimum target water amount or the maximum target water amount is set.

Schließlich ist vorzugsweise vorgesehen, dass die Bewegung des Stellelements der Wasserweiche berührungsfrei überwacht wird. So kann die Bewegung beispielsweise mittels optischer Sensoren oder elektromagnetischer Sensoren erfasst werden. Auch ist es denkbar, die Stromaufnahme eines das Stellelement verlagernden/bewegenden Aktors zu ermitteln. Natürlich ist aber auch eine berührende Erfassung der Bewegung des Stellelements denkbar. Die berührungsfreie Erfassung hat den Vorteil, dass keine die Leistung des Aktors beeinflussende Reibung auftritt.Finally, it is preferably provided that the movement of the adjusting element of the water distributor is monitored without contact. For example, the movement can be detected by means of optical sensors or electromagnetic sensors. It is also conceivable to determine the current consumption of the actuating element displacing / moving actuator. Of course, however, a touching detection of the movement of the actuating element is conceivable. The non-contact detection has the advantage that no friction affecting the performance of the actuator occurs.

Ferner gehört zur Erfindung ein wasserführendes Haushaltsgerät, insbesondere eine Geschirrspülmaschine, mit einer Umwälzpumpe und einer der Umwälzpumpe zugeordneten, insbesondere nachgeschalteten, Wasserweiche mit mindestens einem durch einen Stellelementmotor verstellbares Stellelement zur Richtungsänderung einer Flüssigkeitsströmung durch die Wasserweiche, das mit einer mit der Umwälzpumpe umwälzbaren Mindestfüllwassermenge befüllbar ist, wobei Mittel vorgesehen sind zum Überprüfen einer Fehlfunktion der Wasserweiche und zum Durchführen einer Rundlaufprüfung, wobei bei der Rundlaufprüfung die Mittel überprüfen, ob die Größe der Mindestfüllwassermenge im wasserführenden Haushaltsgerät wenigstens der Größe einer Sollfüllwassermenge zum Gewährleisten des Rundlaufs der Umwälzpumpe entspricht und die Mittel bei der Rundlaufprüfung wenigstens einen Betriebsparameter eines die Umwälzpumpe antreibenden Elektromotors auf einen Rundlauf der Umwälzpumpe hin auswerten. Erfindungsgemäß ist eine Rundlaufprüfung oder ein Nachfüllschritt zum Erhöhen der Mindestfüllmenge durchführbar, wenn keine Fehlfunktion der Wasserweiche vorliegt und die Rundlaufprüfung oder der Nachfüllschritt ist ausgeblendet, wenn die Einrichtung eine Fehlfunktion der Wasserweiche festgestellt.Furthermore, the invention relates to a water-conducting household appliance, in particular a dishwasher, with a circulation pump and one of the circulating pump associated, in particular downstream, water separator with at least one by an actuator motor adjustable actuator for changing direction of a liquid flow through the water gate, which can be filled with a circulating with the circulation pump Mindestfüllwassermenge, said means being provided for checking a malfunction of the water gate and to perform a concentricity test, wherein in the concentricity test, the means check whether the size of the Mindestfüllwassermenge in the water-conducting household appliance at least equal to the size of a Sollfüllwassermenge to ensure the concentricity of the circulation pump and the means in the concentricity test evaluate at least one operating parameter of the circulating pump driving electric motor to a concentricity of the circulating pump out. According to the invention, a concentricity test or a refilling step for increasing the minimum filling quantity can be carried out if there is no malfunction of the water distributor and the concentricity test or the refilling step is hidden if the device detects a malfunction of the water distributor.

In the following, the invention will be explained in more detail with reference to the drawing. Show this
FIG. 1
a water-conducting household appliance in a schematic representation. and
FIG. 2
a procedure for operating the water-conducting household appliance.

Die Figur 1 zeigt in einer vereinfachten Darstellung ein wasserführendes Haushaltsgerät 1, das im vorliegenden Ausführungsbeispiel als Geschirrspülmaschine 2 ausgebildet ist. Dazu weist das wasserführende Haushaltsgerät 1 ein Gehäuse 3 auf, in welchem ein Arbeitsraum 4 ausgebildet ist. In dem Arbeitsraum 4 sind zwei Spülkörbe 5,6 vorgesehen, die zum Halten von Spülgut beziehungsweise Geschirr ausgebildet sind. Der Spülkorb 5 ist dabei oberhalb des Spülkorbs 6 angeordnet. Natürlich können auch weniger oder mehr Spülkörbe vorgesehen sein. Unterhalb des unteren Spülkorbs 6 ist ein Sprüharm 7 angeordnet, der - wie durch Sprühstrahlen angedeutet - eine Spülflotte, z. B. Wasser, das mit Reinigungsmitteln oder Klarspüler versetzt sein kann, von seiner Oberseite an den unteren Spülkorb 6 und das darin befindliche Spülgut abzugeben gestattet. Bei der Abgabe dieser Spülflotte rotiert der untere Sprüharm 7 in bekannter Weise aufgrund des Wasserdrucks der von ihm abgegebenen Spülflotte. Der Sprüharm 7 ist über eine Rohrleitung 8 mit einer Wasserweiche 9 fluidtechnisch verbunden, wobei auf die Wasserweiche 9 später näher eingegangen werden soll. Oberhalb des Spülkorbs 6 ist ein oberer Spülarm 10 angeordnet, der in entsprechender Weise wie der untere Spülarm 8 eine Spülflotte von seiner Oberseite an den oberen Spülkorb 5 und an das darin gegebenenfalls befindliche Spülgut abzugeben gestattet. Auch der obere Spülarm 10 rotiert in Folge des Wasserdrucks der von ihm abgegebenen Spülflotte. Der Spülarm 10 ist über eine Rohrleitung 11 ebenfalls fluidtechnisch mit der Wasserweiche 9 verbunden. Schließlich ist in dem Arbeitsraum 4 optional eine sogenannte Dachbrause 12 oberhalb des Spülkorbs 5 angeordnet, die bevorzugt durch einen rotierbaren Sprüharm 13 gebildet ist, der eine Spülflotte von seiner Unterseite in Richtung auf den oberen Spülkorb 5 und damit auch auf das gegebenenfalls in dem Spülkorb 5 befindliche Spülgut abzugeben gestattet. Die Dachbrause 12 ist über eine Rohrleitung 14 mit der Wasserweiche 9 fluidtechnisch verbunden.The FIG. 1 shows a simplified representation of a water-conducting household appliance 1, which is formed in the present embodiment as a dishwasher 2. For this purpose, the water-conducting household appliance 1 a housing 3, in which a working space 4 is formed. In the working space 4, two rinsing baskets 5.6 are provided, which are designed to hold items to be washed or dishes. The washing basket 5 is arranged above the washing basket 6. Of course, fewer or more rinse baskets can be provided. Below the lower Spülkorbs 6, a spray arm 7 is arranged, which - as indicated by spraying - a rinsing liquor, z. As water, which may be offset with detergents or rinse aid, allowed to leave from its top to the lower washing basket 6 and the items located therein. At the delivery This rinsing liquor, the lower spray arm 7 rotates in a known manner due to the water pressure of the rinsing liquor discharged by it. The spray arm 7 is fluidly connected via a pipe 8 with a water switch 9, wherein the water switch 9 will be discussed later. Above the washing basket 6, an upper washing arm 10 is arranged, which allows in a similar manner as the lower washing arm 8 a rinsing liquor from its upper side to the upper washing basket 5 and to the items optionally located therein. The upper rinsing arm 10 also rotates as a result of the water pressure of the rinsing liquor dispensed by it. The flushing arm 10 is also fluidly connected to the water switch 9 via a pipe 11. Finally, in the working space 4 optionally a so-called overhead shower 12 is arranged above the washing basket 5, which is preferably formed by a rotatable spray arm 13, a washing liquor from its underside in the direction of the upper washing basket 5 and thus also on the optionally in the washing basket. 5 to leave the items to be washed. The overhead shower 12 is fluidly connected via a pipe 14 to the water switch 9.

Die Wasserweiche 9 weist unterschiedliche Anschlüsse für die Rohrleitungen 11 und 14 sowie einen Anschluss für die Druckseite einer Umwälzpumpe 15 auf. Der Umwälzpumpe 15 ist ein Elektromotor 16 zum Antreiben der Umwälzpumpe 15 zugeordnet. Der Arbeitsraum 4 weist in seinem Bodenbereich eine Sammelvorrichtung 17 für in dem Arbeitsbereich befindliche Flüssigkeit auf, die im Wesentlichen als Schräge ausgebildet ist, um Flüssigkeiten zu einer Rohrleitung 18 zu führen, welche mit der Saugseite der Umwälzpumpe 15 verbunden ist. Die mittels der Sammelvorrichtung in dem Arbeitsraum 4 beziehungsweise in dem Nassbereich gesammelte Flüssigkeit wird über die Rohrleitung 18 der Umwälzpumpe 15 zugeführt, welche wiederum die Flüssigkeit zu der ihr nachgeschalteten Wasserweiche 9 fördert.The water switch 9 has different connections for the pipes 11 and 14 and a connection for the pressure side of a circulating pump 15. The circulation pump 15 is associated with an electric motor 16 for driving the circulation pump 15. The working space 4 has, in its bottom area, a collecting device 17 for liquid located in the working area, which is designed essentially as a slope in order to convey liquids to a pipeline 18 which is connected to the suction side of the circulating pump 15. The liquid collected by means of the collecting device in the working space 4 or in the wet area is fed via the pipeline 18 to the circulating pump 15, which in turn conveys the liquid to the downstream water divider 9.

Die Wasserweiche 9 umfasst wenigstens ein hier nicht näher dargestelltes Stellelement, das in unterschiedliche Stellung durch einen hier nicht dargestellten Stellelemenmotor derart bewegbar ist, dass Spülwasser beziehungsweise Spülflotten in jeweils festgelegter Weise an die erwähnten Rohrleitungen 8,11 und 14 abgegeben werden können. Als Stellelement weist die Wasserweiche 9 eine mit Durchströmungsöffnungen versehene Drehscheibe auf. Wasserweichen 9 mit Drehscheiben sind allgemein bekannt, sodass hier auf die genaue Ausführung der Wasserweiche 9 nicht eingegangen werden soll. Der Wasserweiche 9 zugeordnet ist ein Aktor, insbesondere elektromotorischer Aktor, der zum Bewegen beziehungsweise Verdrehen der Drehscheibe dient.The water switch 9 comprises at least one adjusting element which is not shown here in detail, which is movable in different position by a Stellelemenmotor not shown here, that rinsing water or rinsing liquors can be delivered in a fixed manner to the aforementioned pipes 8,11 and 14. As a control element, the water distributor 9 has a rotary disc provided with flow openings. Waters 9 with turntables are well known, so it should not be discussed here on the exact execution of the water switch 9. The water switch 9 is associated with an actuator, in particular electromotive actuator, which serves to move or rotate the turntable.

Schließlich weist das Haushaltsgerät 1 Mittel zum Durchführen einer Rundlaufprüfung mit der Umwälzpumpe 15 und zur Funktionsüberwachung, d.h. zum Überwachen der Bewegung des Stellelements der Wasserweiche 9 mit der Wasserweiche 9 auf, die hierzu mit der Wasserweiche verbunden ist. Diese Mittel sind im vorliegenden Ausführungsbeispiel in einer Einrichtung 19 zusammengefasst, können jedoch auch als zwei getrennte Einheiten ausgebildet sein. Zur Rundlaufprüfung erfasst die Einrichtung 19 mittels eines geeigneten Sensors oder einer geeigneten Schaltung las Betriebsgröße den Motor-Ist-Strom des die Umwälzpumpe 15 antreibenden Elektromotors 16. Im Normalbetrieb stellt die Einrichtung 19 die Leistung der Umwälzpumpe 15 (beziehungsweise des antreibenden Elektromotors) und/oder die Füllwassermenge für den Arbeitsraum 4 des Haushaltsgeräts 1 derart ein, dass genug Flüssigkeit, z. B. Wasser für einen Rundlauf der Umwälzpumpe 15 zur Verfügung steht. Ein berührungsfrei arbeitender Sensor 20 ist dem Stellelement der Wasserweiche 9 zugeordnet und mit der Einrichtung 19 verbunden, sodass die Einrichtung 19 die Bewegung des Stellelements der Wasserweiche 9 mittels des Sensors 20 erfasst.Finally, the domestic appliance 1 comprises means for performing a concentricity test with the circulation pump 15 and for function monitoring, i. for monitoring the movement of the control element of the water switch 9 with the water switch 9, which is for this purpose connected to the water switch. These means are combined in the present embodiment in a device 19, but may also be formed as two separate units. For concentricity testing, the device 19 detects the actual motor current of the electric motor 16 driving the circulating pump 15 by means of a suitable sensor or suitable circuit. In normal operation, the device 19 adjusts the power of the circulating pump 15 (or of the driving electric motor) and / or the filling water quantity for the working space 4 of the household appliance 1 such that enough liquid, for. B. water for a concentricity of the circulation pump 15 is available. A non-contact sensor 20 is assigned to the control element of the water switch 9 and connected to the device 19 so that the device 19 detects the movement of the control element of the water switch 9 by means of the sensor 20.

Anhand der Figur 2 soll nunmehr ein Verfahren zum Betreiben des wasserführenden Haushaltsgeräts 1 erläutert werden. Zunächst wird in einem Schritt 22 über das Bedienfeld 21 ein gewünschtes Spülprogramm durch den Benutzer ausgewählt beziehungsweise vorgegeben. Entsprechend dem gewählten Programm wird in einem darauffolgenden Schritt 23 eine Füllwassermenge bestimmt und dem Arbeitsraum 4 zugeführt. In dem folgenden Schritt 24 wird mittels der Einrichtung 19 und des Sensors 20 die Bewegung des Stellelements der Wasserweiche 9 überprüft. Wird dabei festgestellt, dass die Wasserweiche 9 beziehungsweise das Stellelement der Wasserweiche 9 stillsteht (j) und somit die gewünschte Position zum Einstellen bestimmter Spülflotten eingenommen hat, wird das Verfahren in einem Schritt 25 weitergeführt, in welchem die Rundlaufprüfung zur Feststellung des Rundlaufs der Umwälzpumpe 15 beziehungsweise zur Überprüfen der Mindestgröße einer Füllwassermenge durchgeführt wird. Es kann ferner ein Nachfüllschritt folgen, mit dem die Füllwassermenge erhöht wird.Based on FIG. 2 Now, a method for operating the water-conducting household appliance 1 will be explained. First, in a step 22, a desired wash program is selected or predetermined by the user via the control panel 21. In accordance with the selected program, a filling water quantity is determined in a subsequent step 23 and supplied to the working space 4. In the following step 24, the movement of the actuating element of the water distributor 9 is checked by means of the device 19 and the sensor 20. If it is found that the water switch 9 or the control element of the water switch 9 is stationary (j) and thus has taken the desired position for setting certain rinsing liquors, the method is continued in a step 25, in which the concentricity test to determine the concentricity of the circulation pump 15th or to check the minimum size of a filling water quantity is performed. It may also follow a refilling step, which increases the amount of filling water.

Wird im Schritt 24 jedoch festgestellt, dass das Stellelement der Wasserweiche 9 nicht zum Stillstand gekommen ist, sondern z.B. stattdessen als Fehlerfall eine Dauerbewegung vorliegt (n), wird in einem Schritt 26 weiter verfahren. In dem Schritt 26 wird insbesondere in Abhängigkeit von dem gewählten Spülvorgang entschieden, dass die Rundlaufprüfung ausgeblendet und die Wasserweiche abgeschaltet beziehungsweise ausgeschaltet wird. Zuerst wird in einem Schritt 27 zunächst die Rundlaufprüfung ausgeblendet. Hierdurch wird gewährleistet, dass bei Auftreten einer Fehlfunktion der Wasserweiche 9 z. B. bei Erfassen einer Dauerbewegung des Stellelements, diese nicht dazu führt, dass eine zu große Füllwassermenge dem Arbeitsraum 4 beziehungsweise des Haushaltsgeräts 1 zugeführt wird, die dazu führen könnten, dass Flüssigkeit aus dem Haushaltsgerät 1 austritt. Stattdessen wird bevorzugt in einem darauffolgenden Schritt 28 eine Mindest-Füllwassermenge oder eine Maximal-Füllwassermenge eingestellt, z. B. durch zeitliches Füllen, d. h. durch eine Ventilöffnung für eine bestimmte Zeitdauer. Die Mindest-Füllwassermenge gewährleistet den Rundlauf der Umwälzpumpe 15 bei minimalem Wasserverbrauch. Die Maximal-Füllwassermenge gewährleistet eine vollständige Reinigung des Spülguts sowie den Rundlauf der Umwälzpumpe 15 und ist dahingehend begrenzt, dass der Arbeitsraum 4 nicht überfüllt wird.However, if it is determined in step 24 that the actuator of the water switch 9 has not come to a standstill, but e.g. instead a continuous movement (n) is present as an error case, a further step is taken in a step 26. In step 26 it is decided, in particular depending on the selected flushing process, that the concentricity check is hidden and the water switch is switched off or switched off. First, in a step 27, first the concentricity test is hidden. This ensures that in case of malfunction of the water switch 9 z. B. when detecting a continuous movement of the control element, this does not cause a too large amount of filling water is supplied to the working space 4 and the household appliance 1, which could lead to liquid exiting the household appliance 1. Instead, a minimum filling water quantity or a maximum filling water quantity is preferably set in a subsequent step 28, z. B. by time filling, d. H. through a valve opening for a certain period of time. The minimum filling water volume ensures the concentricity of the circulation pump 15 with minimal water consumption. The maximum amount of filling water ensures complete cleaning of the items to be washed and the concentricity of the circulating pump 15 and is limited to the effect that the working space 4 is not overfilled.

Ferner wird anschließend an den Schritt 26 in einem Schritt 29 die Wasserweiche 9 abgeschaltet. Hierzu wird zweckmäßigerweise der das Stellelement antreibende Aktor bzw. Stellelementmotor stromlos geschaltet, sodass das Stellelement zum Stillstand kommt. Damit ist der Motor-Ist-Strom des Elektromotors 16 allein abhängig von der Füllwassermenge beziehungsweise des dadurch erzeugten Rundlaufs oder Trockenlaufs der Umwälzpumpe 15.Further, following the step 26 in a step 29, the water switch 9 is turned off. For this purpose, the actuating element or actuating element motor driving the actuating element is expediently switched de-energized, so that the actuating element comes to a standstill. Thus, the actual motor current of the electric motor 16 is solely dependent on the filling water quantity or the concentricity or dry running of the circulating pump 15 generated thereby.

Schließlich kann auch vorgesehen sein, im Falle einer erfolgten Fehlfunktion der Wasserweiche 9 einen im Spülprogramm zum Betrieb des wasserführenden Haushaltsgeräts 1 vorgesehenen Nachfüllschritt zum Erhöhen der Wassermenge auszublenden, um ein Überfüllen des wasserführenden Haushaltsgeräts 1 sowie einen Wasseraustritt auszuschließen.Finally, it can also be provided, in the case of a malfunction of the water distributor 9, to hide a refilling step for increasing the amount of water provided in the washing program for operating the water-conducting household appliance 1 in order to prevent overfilling of the water-conducting household appliance 1 and a water outlet.

Das Verfahren zum Betreiben des Haushaltsgeräts 1 gewährleistet somit auf einfache Art und Weise die Betriebssicherheit des Haushaltsgeräts 1.The method for operating the household appliance 1 thus ensures the operational safety of the household appliance 1 in a simple manner.
