Description

Die Erfindung betrifft eine Haushaltsgeschirrspülmaschine bzw. Geschirrspülmaschine.The invention relates to a domestic dishwasher or dishwasher.

Haushaltsgeräte, wie bspw. Geschirrspül- oder Waschmaschinen weisen eine Steuerung auf, die während eines Programmablaufs verschiedene Gerätekomponenten des Haushaltsgeräts, wie z.B. Pumpenmotoren und/oder Ventile sowie Anzeigelemente ansteuert. Nach Programmablauf werden solange die Steuerung und auch die Anzeigeelemente mit elektrischer Energie versorgt, bis eine Bedienperson manuell durch Betätigen eines Hauptschalters zum Ein- und/oder Ausschalten des Haushaltsgeräts dieses ausschaltet.Domestic appliances, such as dishwashers or washing machines, have a controller which, during a program sequence, can supply various appliance components of the domestic appliance, such as e.g. Pump motors and / or valves and display elements controls. After the program, as long as the controller and the display elements are supplied with electrical energy until an operator manually by pressing a main switch for switching on and / or off the domestic appliance off this.

Aus der JP 60 119990 A sowie der US 4,955,213 A sind Waschmaschinen bekannt, die ein automatisches Abschalten des Hauptschalters der Waschmaschine und damit zwangsläufig aller elektrischer Komponenten der Waschmaschine nach Ablauf einer Zeitspanne ermöglichen. Einem Nutzer einer derartigen Waschmaschine kann somit nach dem Abschalten der Waschmaschine nicht angezeigt werden, dass ein Programmablauf beendet wurde. Ähnliche Haushaltsgeräte beziehungsweise Geschirr- oder Waschmaschinen sind aus der JP 60 048789 A , der DE 103 08 204 B3 , der DE 10 2006 029708 A1 , der US 5,150,489 A sowie der DE 43 43 105 A1 bekannt.From the JP 60 119990 A as well as the US 4,955,213 A Washing machines are known which allow automatic shutdown of the main switch of the washing machine and thus inevitably all electrical components of the washing machine after a period of time. A user of such a washing machine can thus not be displayed after switching off the washing machine that a program has been completed. Similar household appliances or dishes or washing machines are from the JP 60 048789 A , the DE 103 08 204 B3 , the DE 10 2006 029708 A1 , the US 5,150,489 A as well as the DE 43 43 105 A1 known.

Bei der Waschmaschine der US 2003/025395 A1 werden von einem Leistungskontrollsystem "power control system" 14 (siehe Figur 3), an dem bei eingestecktem Netzkabel Netzspannung ("line electricity in") anliegt, diejenigen Komponenten (standby/low power components") 54, die wenig elektrische Leistung benötigen, durch einen "stand-by /low power circuitry/logic"- Schaltkreis 64, ständig, d.h. immer mit geringer elektrischer Leistung versorgt (siehe [0005] - [0007] und [0011], [0012]). Wird vom Benutzer über einen Bedienschalter ein Waschprogramm gewählt, so erzeugt ein Prozessor 60 ein Kontrollsignal 70 an einen Schalter bzw. Schaltkreis "switch/switch circuitry/logic" 68, der die durch eine "operating power circuitry/logic" 66 bereitgestellte, aus der Netzelektrizität gewonnene Betriebsspannung an Komponenten "operating power components" 52 mit höherer geforderter Betriebsleistung durchschaltet.In the washing machine of US 2003/025395 A1 are from a power control system "power control system" 14 (see FIG. 3 ) to which mains power is applied when the power cord is plugged in, those components (standby / low power components) 54 which require little electrical power are provided by a stand-by / low power circuitry / logic circuit 64, continuously , ie always supplied with low electrical power (see [0005] - [0007] and [0011], [0012]).) If a washing program is selected by the user via an operating switch, a processor 60 generates a control signal 70 to a Switch or circuit "switch / switch circuitry / logic" 68, which switches through the operating voltage obtained by the "operating power circuitry / logic" 66, obtained from the mains electricity, to components "operating power components" 52 with higher required operating power.

Auch wenn kein Waschprogramm läuft, verbraucht die Waschmaschine elektrische Energie für die permanent in standby -Bereitschaft gehaltenen "standby/low power components 54".Even if no washing program is running, the washing machine consumes electrical energy for the standby / low power components 54 permanently kept in standby readiness.

Die Aufgabe der Erfindung ist daher, eine Haushaltsgeschirrspülmaschine bzw. Geschirrspülmaschine mit reduziertem Energieverbrauch bereitzustellen.The object of the invention is therefore to provide a domestic dishwasher or dishwasher with reduced energy consumption.

Die Lösung der o.g. Aufgabe geht aus von einer Geschirrspülmaschine wenigstens aufweisend eine Steuereinrichtung zur Steuerung von elektrischen Verbrauchern aufweisenden Gerätekomponenten der Geschirrspülmaschine während eines Programmablaufs.The solution of the o.g. Task is based on a dishwasher at least comprising a control device for controlling device components of the dishwasher having electrical consumers during a program sequence.

Erfindungsgemäß ist vorgesehen, dass wenigstens ein Schaltmittel zum wenigstens teilweisen stromlos Schalten der Steuereinrichtung nach Ende des Programmablaufs vorgesehen ist. Somit wird eine Energieersparnis auf überraschend einfache Weise dadurch erreicht, dass nach Programmablauf die Steuereinrichtung insgesamt oder nur zum Teil durch stromlos Schalten von einem hausseitigen Versorgungsnetz getrennt wird.According to the invention it is provided that at least one switching means for at least partially de-energized switching of the control device is provided after the end of the program flow. Thus, an energy saving in a surprisingly simple manner is achieved in that after the program, the control device is completely or only partially separated by de-energized switching from a home-side power supply.

Vorzugsweise ist vorgesehen, dass ein Verzögerungsglied zum stromlos Schalten nach Ablauf einer vorgegebenen Zeitdauer vorgesehen ist. So ist es möglich, dass z.B. für eine Zeitdauer von 30 Minuten die Geschirrspülmaschine bzw. Haushaltsgeschirrspülmaschine mittels akustischer und/oder optischer Signale einer Bedienperson einen Programmablauf signalisiert. Nach Ablauf dieser Zeitdauer wird die Haushaltsgeschirrspülmaschine bzw. Geschirrspülmaschine durch stromlos Schalten vom hausseitigen Versorgungsnetz getrennt. Dabei kann vorzugsweise vorgesehen sein, dass die vorgebbare Zeitdauer manuell von einer Bedienperson eingestellt und/oder das Verzögerungsglied vollständig deaktiviert werden kann.It is preferably provided that a delay element is provided for de-energized switching after a predetermined period of time. So it is possible that e.g. for a period of 30 minutes, the dishwasher or domestic dishwasher indicates a program sequence by means of acoustic and / or optical signals of an operator. After this period of time, the household dishwasher or dishwasher is disconnected from the house-side supply network by de-energized switching. In this case, it can preferably be provided that the predefinable time period can be set manually by an operator and / or the delay element can be completely deactivated.

Dabei ist vorgesehen, dass die Steuereinrichtung wenigstens eine erste Bauteilgruppe zur Steuerung der Geschirrspülmaschine bzw. Haushaltsgeschirrspülmaschine vor Beginn und nach Beendigung eines Programmablaufs aufweist und eine zweite Bauteilgruppe zur Steuerung der Geschirrspülmaschine bzw. Haushaltsgeschirrspülmaschine während eines Programmablaufs aufweist.It is provided that the control device has at least one first component group for controlling the dishwasher or domestic dishwasher before the beginning and after completion of a program flow and has a second component group for controlling the dishwasher or household dishwasher during a program sequence.

Die erste Bauteilgruppe umfasst wenigstens ein Bedien- und/oder Anzeigemodul zur Steuerung von Bedien- und/oder Anzeigeelementen, während die zweite Bauteilgruppe wenigstens ein Steuermodul zur Ansteuerung von Gerätekomponenten während eines Programmablaufs aufweist.The first component group comprises at least one operating and / or display module for controlling operating and / or display elements, while the second component group has at least one control module for controlling device components during a program run.

Es ist ferner vorgesehen, dass wenigstens ein Schaltmittel zum stromlos Schalten der zweiten Bauteilgruppe vorgesehen ist und das Schaltmittel mittels eines ersten Verzögerungsgliedes betätigt wird, das in Signalverbindung mit der ersten Bauteilgruppe ist. Dabei ist während einer voreingestellten Zeitdauer bis zum eigentlichen Programmstart der Geschirrspülmaschine lediglich die mit reduziertem Energiebedarf arbeitende erste Bauteilgruppe zugeschaltet und die Stromversorgung zur zweiten Bauteilgruppe unterbrochen. Erst zum Programmstart wird das Schaltmittel mittels des Verzögerungsglieds geschlossen und die zweite Bauteilgruppe aktiviert. Die zweite Bauteilgruppe zur Ansteuerung von Gerätekomponenten wird nach Programmablauf durch stromlos Schalten vom hausseitigen Versorgungsnetz getrennt, während die erste Bauteilgruppe zur Steuerung von Bedien- und/oder Anzeigeelementen weiterhin mit elektrischer Energie versorgt wird. Dies ermöglicht es, durch akustische und/oder optische Signale eine Bedienperson über einen Programmablauf zu informieren.It is further provided that at least one switching means for normally switching the second component group is provided and the switching means is actuated by means of a first delay element, which is in signal communication with the first component group. In this case, during a preset time period until the actual program start of the dishwasher, only the first component group operating with reduced energy requirement is switched on and the power supply to the second component group is interrupted. Only at the start of the program, the switching means is closed by means of the delay element and the second component group activated. The second group of components for controlling device components is separated after program flow by de-energized switching from the house-side power supply, while the first group of components for controlling control and / or display elements continues to be supplied with electrical energy. This makes it possible to inform by acoustic and / or optical signals an operator about a program flow.

Hierzu steht vorzugsweise das wenigstens eine Schaltmittel mit der ersten Bauteilgruppe in Wirkverbindung, so dass durch ein Steuersignal der ersten Bauteilgruppe ein Schaltvorgang des wenigstens einen Schaltmittels ausgelöst werden kann.For this purpose, preferably the at least one switching means is in operative connection with the first component group, so that a switching operation of the at least one switching means can be triggered by a control signal of the first component group.

Es ist ferner vorgesehen, dass ein zweites Schaltmittel zum stromlos Schalten wenigstens der ersten Bauteilgruppe vorgesehen ist. Hierzu steht die erste Bauteilgruppe mit dem zweiten Schaltmittel in Wirkverbindung, insbesondere um ein stromlos Schalten nach Ende des Programmablaufs zu bewirken.It is further provided that a second switching means is provided for normally switching at least the first component group. For this purpose, the first group of components is in operative connection with the second switching means, in particular to effect a de-energized switching after the end of the program sequence.

Außerdem ist ein weiteres Verzögerungsglied zum stromlos Schalten der ersten Bauteilgruppe nach Ablauf einer Zeitdauer vorgesehen. So kann auch die erste Bauteilgruppe nach Ablauf einer vorgebbaren Zeitdauer nach dem Programmablauf durch stromlos Schalten vom hausseitigen Versorgungsnetz getrennt werden.In addition, a further delay element for the currentless switching of the first group of components is provided after a period of time. Thus, the first group of components can be separated from the home-side supply network after expiry of a predetermined period of time after the program flow by de-energized switching.

Hierzu ist vorzugsweise das zweite Schaltmittel als Hauptschalter ausgebildet, mit dem die Haushaltsgeschirrspülmaschine wenigstens manuell eingeschaltet werden kann.For this purpose, the second switching means is preferably designed as a main switch, with which the domestic dishwasher can be switched on at least manually.

Schließlich ist vorzugsweise vorgesehen, dass der Hauptschalter nach einem Programmablauf die Haushaltsgeschirrspülmaschine selbsttätig vom elektrischen Versorgungsnetz trennt.Finally, it is preferably provided that the main switch automatically disconnects the household dishwasher from the electrical supply network after a program run.

By way of example, the display unit 9 is connected to a supply line 19.

Die Steuereinrichtung 8 weist außerdem eine erste Bauteilgruppe 21 auf, die wenigstens ein Bedien- und/oder Anzeigeelektronikbauteil aufweist. Ferner weist die Steuereinrichtung 8 eine zweite Bauteilgruppe 23 auf, die ein Steuerelektronikbauteil aufweist. Beide Bauteilgruppen 21, 23, werden jeweils über weitere Versorgungsleitungen 25, 27 vom Netzteil 15 mit elektrischer Energie versorgt. Die erste Bauteilgruppe 21 mit dem Bedien- und/oder Anzeigeelektronikbauteil dient einerseits als Eingabeeinheit zur Programmeingabe mittels der Programmschalter 3, 5, 7 sowie der Betätigungselemente 13, von denen in der Fig. 2 lediglich beispielhaft ein Betätigungselement 13 gezeigt ist, mit dem die Zeitdauer Δtv einstellbar ist. Die erste Bauteilgruppe 21 leitet außerdem entsprechende Steuersignale an die Anzeigeeinheit 9.The control device 8 also has a first component group 21 which has at least one operating and / or display electronic component. Furthermore, the control device 8 has a second component group 23, which has a control electronic component. Both component groups 21, 23 are each supplied with electrical energy via additional supply lines 25, 27 from the power supply 15. The first component group 21 with the operating and / or display electronic component serves on the one hand as an input unit for program input by means of the program switch 3, 5, 7 and the actuating elements 13, of which in the Fig. 2 merely an example of an actuator 13 is shown, with which the time period .DELTA.t v is adjustable. The first component group 21 also passes corresponding control signals to the display unit 9.

Die erste Bauteilgruppe 21 ist außerdem in Signalverbindung mit der zweiten Bauteilgruppe 23, die während einer vorgegebenen Betriebsdauer einen Spülgang der Geschirrspülmaschine steuert. Entsprechend ist die zweite Bauteilgruppe 23 über Signalleitungen 29 mit den nicht gezeigten elektrischen Gerätekomponenten der Geschirrspülmaschine in Verbindung.The first component group 21 is also in signal communication with the second component group 23, which controls a rinse cycle of the dishwasher during a predetermined period of operation. Accordingly, the second component group 23 is connected via signal lines 29 with the electrical device components of the dishwasher, not shown in connection.

In der vom Netzteil 15 zum Steuerelektronikbauteil 23 geführten Versorgungsleitung 27 ist als ein Schaltmittel 31 ein Schalter vorgesehen, der die zweite Bauteilgruppe 23 vom Netzteil 15 bzw. vom Versorgungsnetz 17 trennen und somit stromlos schalten oder damit verbinden kann. Das Schaltmittel 31 wird mittels eines Verzögerungsgliedes 33 betätigt, das in Signalverbindung mit der ersten Bauteilgruppe 21 ist. Dabei hält das Verzögerungsglied 33 das Schaltmittel 31 während der gesamten voreingestellten Zeitdauer Δtv in seiner Offenstellung. Das heißt, dass während der voreingestellten Zeitdauer Δtv bis zum eigentlichen Programmstart der Geschirrspülmaschine die Stromversorgung zum Steuerelektronikbauteil 23 unterbrochen ist. Erst zum Programmstart wird das Schaltmittel 31 mittels des Verzögerungsglieds 33 geschlossen und entsprechend die zweite Bauteilgruppe 23 aktiviert. Auf diese Weise kann während des Ablaufes der voreingestellten Zeitdauer Δtv das üblicherweise mit erhöhtem Energiebedarf im Standby-Modus arbeitende zweite Bauteilgruppe 23 stromlos geschaltet werden, während lediglich die mit reduziertem Energiebedarf arbeitende erste Bauteilgruppe 21 zugeschaltet ist.In the guided from the power supply 15 to the control electronics component 23 supply line 27, a switch is provided as a switching means 31, the second component group 23 from Disconnect power supply 15 or from the power grid 17 and thus switch off or connect it to power. The switching means 31 is actuated by means of a delay element 33 which is in signal connection with the first component group 21. In this case, the delay element 33 holds the switching means 31 during the entire preset period of time Δt v in its open position. This means that during the preset period of time Δt v until the actual start of the dishwasher, the power supply to the control electronic component 23 is interrupted. Only at the start of the program, the switching means 31 is closed by means of the delay element 33 and the second component group 23 is activated accordingly. In this way, during the expiration of the preset period of time Δt v, the second component group 23, which normally operates with increased energy demand in standby mode, can be de-energized, whereas only the first component group 21 operating with reduced energy requirement is switched on.

Wie aus der Fig. 2 weiter hervorgeht, ist das Schaltmittel 31 über eine Signalleitung 35 mit der zweiten Bauteilgruppe 23 verbunden. Nach erfolgtem Spülgang der Geschirrspülmaschine erzeugt die zweite Bauteilgruppe 23 ein Steuersignal, das das Schaltmittel 31 wieder in seine Offenstellung verbringt. Auf diese Weise ist auch nach Ablauf des Spülganges die zweite Bauteilgruppe 23 wieder vom elektrischen Versorgungsnetz 17 getrennt.Like from the Fig. 2 further shows, the switching means 31 is connected via a signal line 35 to the second component group 23. After the rinse cycle of the dishwasher, the second component group 23 generates a control signal, which spends the switching means 31 back to its open position. In this way, the second component group 23 is again disconnected from the electrical supply network 17 even after the rinse cycle.

In der Fig. 3 ist gemäß dem zweiten Ausführungsbeispiel ein weiteres Prinzipschaltbild der Steuereinrichtung 8 der Geschirrspülmaschine dargestellt. Der Aufbau und die Funktionsweise der darin gezeigten Steuereinrichtung 8 ist im Wesentlichen identisch mit dem in der Fig. 2 dargestelltem Ausführungsbeispiel. Insoweit wird Bezug auf dessen Beschreibung genommen.In the Fig. 3 is shown according to the second embodiment, another block diagram of the control device 8 of the dishwasher. The structure and operation of the controller 8 shown therein is substantially identical to that shown in FIG Fig. 2 illustrated embodiment. In that regard, reference is made to its description.

Im Unterschied zur Fig. 2 ist die zweite Bauteilgruppe 23 nicht unmittelbar mit dem Schaltmittel 31 in Signalverbindung. Vielmehr ist die zweite Bauteilgruppe 23 mit einem als Hauptschalter dienenden zweiten Schaltmittel 11 gekoppelt. Nach Ablauf des Spülganges kann daher ebenfalls von der zweiten Bauteilgruppe 23 ein entsprechendes Signal erzeugt und zum zweiten Schaltmittel 11 geleitet werden, das die gesamte Geschirrspülmaschine vom hausseitigen Versorgungsnetz 17 abtrennt. Dadurch können Energieverluste nach erfolgtem Programmablauf vollständig vermieden werden.In contrast to Fig. 2 the second component group 23 is not directly in signal communication with the switching means 31. Rather, the second component group 23 is coupled to a serving as a main switch second switching means 11. After expiration of the rinse cycle, therefore, a corresponding signal can also be generated by the second component group 23 and directed to the second switching means 11, which separates the entire dishwasher from the domestic supply network 17. As a result, energy losses can be completely avoided after the program has been completed.
