Die Erfindung betrifft ein Haushaltsgerät, insbesondere eine Haushalts- Geschirrspülmaschine, wenigstens aufweisend eine Betriebsanzeige mit wenigstens einem optischen und/oder akustischen Anzeigemittel, das wenigstens zum Anzeigen und/oder Signalisieren eines Abschlusses eines Behandlungsvorgangs ausgebildet ist. The invention relates to a household appliance, in particular a domestic dishwasher, at least comprising an operating display with at least one optical and / or acoustic display means which is designed at least for displaying and / or signaling a conclusion of a treatment process.
Bei der Bewertung von Haushaltsgeräten durch Verbraucherorganisationen spielt der Energieverbrauch des Haushaltsgerätes, insbesondere auch dessen Jahresenergiebilanz, eine bedeutende Rolle. Haushaltsgeräte weisen eine Betriebsanzeige mit wenigstens optischen Anzeigemitteln, zum Beispiel LEDs, auf, mit denen während des Betriebs des Haushaltsgeräts Betriebsparameter, etc., und nach Abschluss eines In the evaluation of household appliances by consumer organizations, the energy consumption of the household appliance, in particular its annual energy balance, plays an important role. Household appliances have an operation display with at least optical display means, for example LEDs, with which during operation of the household appliance operating parameters, etc., and after completion of a
Behandlungsvorgangs gemäß eines Programms angezeigt werden kann, dass der Behandlungsvorgang abgeschlossen wurde. Jedoch bleibt das Haushaltsgerät nach dem Programmende so lange am Stromversorgungsnetz, bis der Kunde aktiv eingreift und das Haushaltsgerät durch Betätigung des Hauptschalters ausschaltet.  Treatment process can be displayed according to a program that the treatment process has been completed. However, the household appliance remains at the end of the program on the power grid until the customer actively intervenes and turns off the household appliance by pressing the main switch.
Die Aufgabe der Erfindung besteht darin, ein Haushaltsgerät, insbesondere Haushalts- Geschirrspülmaschine, bereitzustellen, bei dem der Energieverbrauch weiter gesenkt ist. The object of the invention is to provide a domestic appliance, in particular household dishwasher, in which the energy consumption is further reduced.
Erfindungsgemäß ist vorgesehen, dass das mit oder nach Abschluss des According to the invention it is provided that with or after completion of the
Behandlungsvorgangs das wenigstens den Abschluss des Behandlungsvorgangs anzeigende und/oder signalisierende Anzeigemittel für eine vorbestimmte Zeitdauer aktiviert ist. Es kann sich bei der vorbestimmte Zeitdauer um einen festen Wert endlicher Größe handeln, der bspw. in einer Gerätesteuerung abgespeichert ist. Jedoch kann diese Zeitdauer auch einstellbar sein, d.h. variabel, bspw. durch einen Benutzer. In beiden Fällen wird die Anzeige von zumindest dem abgeschlossen Behandlungsvorgang nach Ablauf der Zeitdauer deaktiviert. Dabei kann bspw. das Anzeigemittel mindestens den abgeschlossenen Behandlungsvorgang anzeigen und/oder signalisieren oder andere Informationen, wie z.B. die abgelaufene Programmzeit eines Reinigungsprogramms, die Art des Reinigungsprogramms oder Störungen während des Programmablaufs. Eine Anzeige eines abgelaufenen Behandlungsvorgangs kann z.B. durch Anzeige eines entsprechenden Symbols oder einer abgelaufenen Programmlaufzeit erfolgen. DerTreatment process that is at least the completion of the treatment process indicating and / or signalizing display means activated for a predetermined period of time. It may be at the predetermined period of time to a fixed value of finite size, which is stored, for example, in a device control. However, this period of time may also be adjustable, ie variable, for example by a user. In both cases, the display of at least the completed treatment process after the expiration of the period is disabled. In this case, for example, the display means at least display the completed treatment process and / or signal or other information, such as the elapsed program time of a cleaning program, the type of cleaning program or disturbances during the program flow. An indication of an elapsed treatment process can eg by displaying a corresponding symbol or an elapsed program runtime. Of the
Erfindung liegt die Erkenntnis zugrunde, dass in einer Jahresenergiebilanz der aufgrund des elektrischen Betriebs der optischen Anzeigemittel verursachte Energieverbrauch des Haushaltsgerätes merklich einfließt. Untersuchungen haben ergeben, dass die Zeitdauer zwischen dem Abschluss des eigentlichen Behandlungsvorgangs und einem The invention is based on the finding that, in an annual energy balance, the energy consumption of the household appliance caused by the electrical operation of the optical display means noticeably flows into it. Investigations have shown that the time between the completion of the actual treatment process and a
darauffolgenden Behandlungsvorgang im Bereich von Stunden oder Tagen liegen kann. Für den Fall, dass nach dem Ende des Behandlungsvorgangs der Hauptschalter nicht ausgeschaltet wird, bleiben daher im Stand der Technik insbesondere die optischen Anzeigemittel, die das Programmende anzeigen, bis zum folgenden Behandlungsvorgang aktiviert. Dadurch kann in der Jahresenergiebilanz der Energieverbrauch des subsequent treatment process can be in the range of hours or days. In the event that after the end of the treatment process, the main switch is not turned off, therefore remain in the prior art, in particular the optical display means indicating the end of the program, activated until the subsequent treatment process. Thus, in the annual energy balance of the energy consumption of
Haushaltsgeräts merklich erhöht sein. Mittels der Erfindung können die optischen Household appliance be noticeably increased. By means of the invention, the optical
Anzeigemittel unabhängig von zum Beispiel einer benutzerseitigen Betätigung eines Hauptschalters selbsttätig ausgeschaltet werden. Eine solche Deaktivierung der Display means are automatically switched off independently of, for example, a user-side operation of a main switch. Such deactivation of
Anzeigemittel kann erfolgen, wenn deren Betrieb etwa von einer Steuereinrichtung als nicht erforderlich eingestuft wird. Vor diesem Hintergrund kann erfindungsgemäß der Energieverbrauch des Geräts nach erfolgtem Behandlungsvorgang weitgehend reduziert werden, so dass der Gesamtenergieverbrauch des Haushaltsgerätes entsprechend reduziert ist. Display means may be performed when their operation is deemed by a controller to be unnecessary. Against this background, the energy consumption of the device can be largely reduced according to the invention after the treatment process, so that the total energy consumption of the household appliance is reduced accordingly.
Vorzugsweise ist der Steuerung ist außerdem ein Verzögerungsglied zugeordnet, mit dem eine Zeitdauer einstellbar ist, nach der die Steuerung auf das Ausschaltsignal die Preferably, the controller is also associated with a delay element with which a period of time is set, after which the control on the switch-off the
Anzeigemittel zeitverzögert deaktiviert. Das Verzögerungsglied kann technisch beispielsweise als ein in einer Steuerungseinrichtung integrierter Mikroprozessor realisiert sein. Mit Hilfe des Verzögerungsglieds kann die Betriebsdauer der optischen Display means time-delayed deactivated. The delay element can be technically realized, for example, as a microprocessor integrated in a control device. With the help of the delay element, the operating time of the optical
Anzeigemittel nach Generierung des Ausschaltsignals variabel eingestellt werden. Display means are set variably after generation of the switch-off signal.
Bevorzugt ist es, wenn das Verzögerungsglied mit einem Eingabemittel in Signalverbindung ist, mit dem benutzerseitig die Zeitdauer bis zur Deaktivierung der optischen Anzeigemittel eingestellt werden kann. Der Benutzer kann somit das Betriebsverhalten des Haushaltsgeräts selbst beeinflussen. Das Eingabemittel zur Einstellung der It is preferred if the delay element is in signal connection with an input means with which the user can set the time duration until deactivation of the optical display means. The user can thus influence the operating behavior of the household appliance itself. The input means for setting the
Zeitverzögerung kann unmittelbar in der Bedienblende des Haushaltsgerätes vorgesehen sein. Die Einstellung der Zeitdauer durch das Eingabemittel kann kontinuierlich oder stufenartig erfolgen. Die Zeitdauer kann beispielhaft in einem Bereich zwischen 0 und 60 min. eingestellt werden. Time delay may be provided directly in the control panel of the household appliance. The adjustment of the time duration by the input means can be continuous or stepped. The duration can be exemplified in a range between 0 and 60 min. be set.
Um die benutzerseitige Wahlmöglichkeit bei der Einstellung des Eingabemittels des Verzögerungsglieds zu erweitern, kann mit dem Eingabemittel ein Einstellwert einstellbar sein, bei dem keine Deaktivierung der optischen Anzeigemittel erfolgt. In diesem Fall ist daher die einstellbare Zeitdauer auf„unendlich" eingestellt. Das Eingabemittel kann außerdem bevorzugt auf einen weiteren Einstellwert eingestellt werden, bei dem die Zeitdauer auf„0" gestellt ist. In diesem Fall werden unmittelbar nach Generierung des Ausschaltsignals ohne weitere Zeitverzögerung die optischen Anzeigemittel deaktiviert. In order to expand the user-side option in the setting of the input means of the delay element, with the input means, a setting value can be set, in which no deactivation of the optical display means takes place. In this case, therefore, the settable time is set to "infinite." Also, the input means may be preferably set to another set value at which the time is set to "0". In this case, the optical display means are deactivated immediately after generation of the switch-off signal without any further time delay.
Das Ausschaltsignal zur Deaktivierung der optischen Anzeigemittel kann unmittelbar in Anschluss auf einen abgeschlossenen Behandlungsvorgang des Haushaltsgerätes erzeugt werden. Bevorzugt wird das Ausschaltsignal automatisch durch eine Steuer- einrichtung erzeugt, mit der während eines Behandlungsvorganges Gerätekomponenten, wie etwa die Anzeigemittel oder Umwälz-/Laugenpumpen, angesteuert werden können. The switch-off signal for deactivating the optical display means can be generated directly in connection to a completed treatment process of the household appliance. Preferably, the switch-off signal is automatically generated by a control device with which during a treatment process device components, such as the display means or circulation / lye pumps, can be controlled.
Von der erfindungsgemäßen Steuerung kann bevorzugt eine optische Betriebsanzeige des Haushaltsgerätes deaktiviert werden, die selbst im Standby-Betrieb einen erhöhten Energieverbrauch aufweist. Alternativ dazu kann das gesamte Haushaltsgerät von der Steuerung selbsttätig deaktiviert werden. From the controller according to the invention may preferably be disabled, a visual indicator of the household appliance, which has an increased energy consumption even in standby mode. Alternatively, the entire household appliance can be automatically deactivated by the controller.
Ferner ist vorzugsweise vorgesehen, dass der Einschalter und ein Ausschalter parallel geschaltet angeordnet sind. Das Stromversorgungsnetz kann z.B. an einem Mikroschalter ausgebildeten Einschalter und am parallel dazu geschalteten Schaltglied anliegen. Bei außer Betrieb gesetztem Haushaltsgerät sind sowohl der Einschalter als auch das Schaltglied geöffnet. Durch Druckbetätigung des Mikroschalters kann das deaktivierte, das heißt geöffnete Schaltglied der Selbsthaltekontaktschaltung überbrückt werden, wodurch die Steuereinrichtung mit einem Spannungsimpuls beaufschlagt wird. Der Spannungsimpuls wird über die Steuereinrichtung zur Selbsthaltekontaktschaltung geleitet, wodurch die Selbsthaltekontaktschaltung das Schaltglied schließt. Auf diese Weise fließt Strom vom Netz über das nunmehr geschlossene Schaltglied zur Furthermore, it is preferably provided that the power switch and a circuit breaker are arranged in parallel. The power grid may e.g. abut on a microswitch formed switch and the switching element connected in parallel thereto. When put out of service home appliance, both the power switch and the switching element are open. By pressing the microswitch, the deactivated, that is open switching element of the self-holding contact circuit can be bypassed, whereby the control device is acted upon by a voltage pulse. The voltage pulse is passed via the control device to the self-holding contact circuit, whereby the self-holding contact circuit closes the switching element. In this way, current flows from the network via the now closed switching element
Selbsthaltekontaktschaltung, so dass das Schaltglied stabil geschlossen bleibt, während der Einschalter wieder geöffnet ist. Sobald die Steuereinrichtung das Ausschaltsignal zur Selbsthaltekontaktschaltung leitet, öffnet diese das Schaltglied, wodurch die Self-holding contact circuit, so that the switching element remains stably closed while the power switch is open again. As soon as the control device conducts the switch-off signal to the self-hold contact circuit, this opens the switching element, whereby the
Stromversorgung in das Haushaltsgerät unterbrochen ist. Power supply to the household appliance is interrupted.
Dabei ist vorzugweise vorgesehen, dass an dem Einschalter und dem Ausschalter eine gleich hohe elektrische Spannung anliegt. Dies erlaubt einen besonders einfachen Aufbau. It is preferably provided that an equally high electrical voltage is applied to the power switch and the off switch. This allows a particularly simple structure.
Dabei ist vorzugweise vorgesehen, dass der Einschalter und der Ausschalter einen Ein- und/oder Ausschaltimpuls übertragend mit der Steuereinrichtung verbunden sind. Es ist ferner vorzugweise vorgesehen, dass Netzteil mit dem Einschalter und dem Ausschalter eine Reihenschaltung bildend angeordnet ist. Außerdem ist vorzugsweise vorgesehen, dass die Steuereinrichtung mit dem Netzteil mit elektrischer Energie versorgbar verbunden ist. Es ist ferner vorzugsweise vorgesehen, dass die Betriebsanzeige mit dem Netzteil mit elektrischer Energie versorgbar verbunden ist. Schließlich ist vorzugsweise vorgesehen, dass die Selbsthaltekontaktschaltung einer von der Steuereinrichtung ansteuerbaren Steuerung zugeordnet ist. It is preferably provided that the power switch and the off switch an input and / or off-pulse are transmitted to the control device. It is further preferably provided that the power supply with the power switch and the circuit breaker is arranged forming a series circuit. In addition, it is preferably provided that the control device is connected to the power supply with electrical energy supplied. It is further preferably provided that the operating display is connected to the power supply with electrical energy supplied. Finally, it is preferably provided that the self-holding contact circuit is assigned to a controllable by the controller control.
Die Selbsthaltekontaktschaltung kann bevorzugt ein bistabiles Relais aufweisen, mit dem ein als Schaltglied wirkender Relaiskontakt schaltbar ist. Ein solches bistabiles Relais ist vor allem durch die Eigenschaft gekennzeichnet, dass es im stromlosen Zustand zwei verschiedene stabile Schaltzustände einnehmen kann. Ein Relaiskontakt des bistabilen Relais kann als das Schaltglied in der Hauptversorgungsleitung des Haushaltsgerätes geschaltet sein. Sofern das bistabile Relais mit dem Ausschaltsignal beaufschlagt wird, schaltet es den Relaiskontakt von einem stabilen stromlosen Offen-Zustand in einen stabilen stromlosen Geschlossen-Zustand oder umgekehrt, wodurch das Haushaltsgerät vollständig vom Netz entkoppelt oder damit verbunden ist. Anstelle eines Relais kann auch ein Flipflop, insbesondere ein RS-Flipflop, Verwendung finden. The self-holding contact circuit may preferably have a bistable relay with which a relay contact acting as a switching element can be switched. Such a bistable relay is characterized above all by the property that it can assume two different stable switching states when de-energized. A relay contact of the bistable relay may be connected as the switching element in the main supply line of the household appliance. If the bistable relay is energized with the turn-off signal, it switches the relay contact from a stable de-energized open state to a stable de-energized closed state, or vice versa, whereby the household appliance is completely de-coupled from or connected to the mains. Instead of a relay, a flip-flop, in particular an RS flip-flop, can also be used.
Schließlich ist vorzugsweise vorgesehen, dass die Selbsthaltekontaktschaltung derart mit dem Ausschalter verbunden ist, dass der Ausschalter in einen geöffneten Zustand bringbar ist, so dass auf einfachem Wege eine Trennung von der Versorgungsspannung möglich ist. Ferner wird die Aufgabe der Erfindung gelöst durch ein Verfahren gemäß dem Finally, it is preferably provided that the self-holding contact circuit is connected to the circuit breaker such that the circuit breaker can be brought into an open state, so that a separation of the supply voltage is possible in a simple way. Furthermore, the object of the invention is achieved by a method according to the

In der Hauptversorgungsleitung H ist ein später beschriebenes Schaltglied AS sowie ein Netzteil NT in Reihe geschaltet. The provided in Fig. 1 in the left area of the control panel B microswitch ES is exemplified here as a key switch. With a pressure actuation of the microswitch ES, the household dishwasher can be switched into operational readiness, while in a subsequent pressure actuation the household dishwasher is decoupled from the power supply network. FIG. 2 shows a circuit arrangement in which inter alia the microswitch ES and the operating display BA are integrated. In the circuit arrangement shown, the domestic dishwasher is connected via a main supply line H connected to the power supply network. In the main supply line H, a later-described switching element AS and a power supply NT are connected in series.
Das Netzteil NT wandelt die Netzspannung von bspw. 230 V in eine Niederspannung von 12 V um. Die Niederspannung 12V wird mittels eines in Reihe nach dem Netzteil NT ge- schalteten Reglers RG in eine Niederspannung von 5 V umgewandelt, mit der eineThe power supply unit NT converts the mains voltage of, for example, 230 V into a low voltage of 12 V. The low voltage 12V is converted into a low voltage of 5 V by means of a regulator RG connected in series with the power supply unit NT, with which a low voltage of 5 V is connected
Steuereinrichtung SE versorgt wird. Das Netzteil NT versorgt außerdem über zusätzliche Ausgänge weitere Gerätekomponenten und auch die Betriebsanzeige BA der Haushalts- Geschirrspülmaschine mit Niederspannung. Die Steuereinrichtung SE ist in einem nicht näher dargestellten Steuermodul integriert und steuert während der Ausführung eines Spülprogramms über eine erste Signalleitung SL1 die optischen Anzeigemittel AZ der Betriebsanzeige BA sowie weitere Gerätekomponente, etwa die Laugenpumpe oder die Umwälzpumpe, mittels Steuersignalen SE an. Control device SE is supplied. The power supply unit NT also supplies additional device components via additional outputs as well as the low-voltage household appliance operating indicator BA. The control device SE is integrated in a control module not shown in detail and controls during the execution of a wash program via a first signal line SL1 the optical display means AZ of the operating display BA and other device component, such as the drain pump or the circulation pump, by means of control signals S E.
Wie aus der Fig. 2 weiter hervorgeht, ist die Steuereinrichtung SE über eine zweite Signalleitung SL2 mit einem bistabilen Relais RE einer Selbsthaltekontaktschaltung SKS verbunden. Dem bistabilen Relais RE ist als Relaiskontakt das bereits erwähnte As is further apparent from FIG. 2, the control device SE is connected via a second signal line SL2 to a bistable relay RE of a self-holding contact circuit SKS. The bistable relay RE is the relay contact already mentioned
Schaltglied AS zugeordnet, das anstelle eines mechanischen Hauptschalters in der Hauptversorgungsleitung H geschaltet ist und als solches eine Hauptschalterfunktion übernimmt, mit der die Haushalts-Geschirrspülmaschine vom Stromversorgungsnetz entkoppelt oder damit verbunden werden kann. In der zweiten Signalleitung SL2 ist ein Verzögerungsglied VG geschaltet. Mittels des Verzögerungsglieds VG kann ein später beschriebenes Ausschaltsignal Saus, das von der Steuereinrichtung SE generiert wird, zeitverzögert zum Relais RE weitergeleitet werden. Associated switching element AS, which is connected in place of a mechanical main switch in the main supply line H and as such assumes a main switch function with which the household dishwasher can be decoupled from the power supply network or connected to it. In the second signal line SL2, a delay element VG is connected. By means of the delay element VG, a switch-off signal S off , which is generated later on and which is generated by the control device SE, can be forwarded to the relay RE in a time-delayed manner.
Das Verzögerungsglied VG ist gemäß der Fig. 2 mit dem von der Bedienblende B getragenen Eingabemittel EM ansteuerbar. Mit dem Eingabemittel EM kann eine The delay element VG can be controlled according to FIG. 2 with the input means EM carried by the control panel B. With the input means EM can a
Zeitdauer At eingestellt werden, nach deren Ablauf das Ausschaltsignal Saus zum Relais RE weitergeleitet wird. At time period are set, the switch-off signal S is relayed from the relay RE after which.
In Abhängigkeit davon, welche Zeitdauer At vom Eingabemittel EM eingestellt ist, wird das in der Steuereinrichtung SE erzeugte Ausschaltsignal Saus vom Verzögerungsglied VG zeitverzögert an das Relais RE weitergeleitet. Durch Einstellung dieser Zeitdauer M kann der Benutzer selbst bestimmen, wie lange nach dem Programmende die optischen Anzeigemittel AZ aktiviert bleiben sollen. Depending on what length of time At is set by said input means EM, is produced in the control unit SE switch-off signal S from the delay element VG delayed forwarded to the relay RE. By setting this period M, the user can determine how long after the end of the program, the optical display means AZ should remain activated.
Erfolgt eine Einstellung der Zeitdauer M auf 0, so wird das Ausschaltsignal Saus unver- züglich zum Relais RE geleitet. In diesem Fall verzichtet daher der Benutzer gänzlich auf eine optische Programmende-Anzeige nach Ablauf des Spülgangs. Erfolgt demgegenüber eine Einstellung der Zeitdauer M auf„unendlich", so bleibt das Relais RE und damit auch die optischen Anzeigemittel AZ nach dem Programmende des Spülgangs dauerhaft aktiviert. In diesem Fall verzichtet der Benutzer auf eine selbsttätige Abschaltung der Haushalts-Geschirrspülmaschine nach Ablauf des Spülgangs. If an adjustment of the time duration M to 0, then the switch-off signal S out immediately to the relay RE is passed. In this case, therefore, the user completely waives an optical program end display after the wash cycle. If, on the other hand, an adjustment of the time duration M to "infinity" remains, the relay RE and thus also the optical display means AZ remain permanently activated after the program end of the wash cycle ,
Bei außer Betrieb gesetzter Haushalts-Geschirrspülmaschine ist sowohl der Mikroschalter ES als auch das Schaltglied AS geöffnet. Die Inbetriebnahme der ausgeschalteten Haushalts-Geschirrspülmaschine erfolgt mittels einer Druckbetätigung des Mikroschalters ES, bei der das anfänglich noch geöffnete Schaltglied AS überbrückt wird. Durch dieWhen put out of service domestic dishwasher both the micro switch ES and the switching element AS is open. The commissioning of the household dishwasher switched off by means of a pressure actuation of the microswitch ES, in which the initially open switching element AS is bridged. By the
Druckbetätigung des Mikroschalters ES wird ein Spannungsimpuls bereitgestellt, der über das Netzteil NT und über den Regler RG zur Steuereinrichtung SE geleitet wird. Pressure actuation of the microswitch ES, a voltage pulse is provided, which is passed through the power supply NT and the controller RG to the control device SE.
Die Steuereinrichtung SE leitet daraufhin ein Einschaltsignal Sein über eine dritte The control unit SE then forwards a switch S via a third one
Signalleitung SL3 weiter an das bistabile Relais RE, worauf dessen Relaisspule anzieht und das Schaltglied AS vom stromlos stabilen Offen-Zustand in einen stromlos stabilen Geschlossen-Zustand verbracht wird. Auf diese Weise ist der nach der Druckbetätigung wieder offene Mikroschalter ES vom nunmehr geschlossenen Schaltglied AS überbrückt, wodurch am Netzteil NT die Netzspannung anliegt. Signal line SL3 continues to the bistable relay RE, whereupon its relay coil attracts and the switching element AS is moved from the normally open stable state to a normally closed state. In this way, after the pressure actuation again open microswitch ES is bridged by the now closed switching element AS, whereby the mains voltage is applied to the power supply NT.
Die Haushalts-Geschirrspülmaschine ist somit betriebsbereit geschaltet, so dass nachfolgend mittels der Eingabemittel E ein Spülprogramm gestartet werden kann. Nach dem Ende des Spülprogramms schaltet die Steuereinrichtung SE die The household dishwasher is thus switched ready for operation, so that subsequently by means of the input means E, a washing program can be started. After the end of the washing program, the control device SE switches the
Gerätekomponenten, etwa Laugen- oder Umwälzpumpe, aus. Device components, such as lye or circulation pump off.
Unmittelbar nach Ablauf des Spülprogramms erzeugt die Steuereinrichtung SE außerdem einen weiteren Spannungsimpuls, der als Ausschaltsignal Saus über die zweite Signalleitung SL2 das bistabile Relais RE ansteuert. Daraufhin schaltet das Relais RE das Schaltglied AS von der Geschlossen-Stellung in die Offen-Stellung, wodurch die Immediately after the end of the wash program, the control device SE also generates a further voltage pulse, which activates the bistable relay RE as the switch-off signal S off via the second signal line SL2. Then the relay RE switches the Switching member AS from the closed position to the open position, whereby the
Haushalts-Geschirrspülmaschine vollständig vom Stromversorgungsnetz getrennt ist.  Household dishwasher is completely disconnected from the mains.
Das Schaltglied AS des Relais RE wirkt somit als ein Hauptschalter, der selbsttätig nach Beendigung des Spülgangs das Netzteil NT der Haushalts-Geschirrspülmaschine vom Stromversorgungsnetz trennt. Auf diese Weise ist erreicht, dass nach dem The switching element AS of the relay RE thus acts as a main switch, which automatically disconnects the power supply NT of the domestic dishwasher from the power supply network after completion of the rinse cycle. In this way it is achieved that after the
Programmende insbesondere auch eine Stromversorgung über das Netzteil NT zu dem optischen Anzeigemittel AZ der Betriebsanzeige BA unterbrochen ist.  End of the program in particular a power supply via the power supply NT is interrupted to the optical display means AZ of the power indicator BA.
Wie aus der Fig. 2 weiter hervorgeht, ist der Mikroschalter ES über eine Eingangsleitung EL direkt mit der Steuereinrichtung SE in Signalverbindung. Der bei einer manuellenAs is further apparent from FIG. 2, the microswitch ES is in signal connection via an input line EL directly to the control device SE. The case of a manual
Druckbetätigung des Mikroschalters ES bereitgestellte Spannungsimpuls wird daher auch unmittelbar bis zur Steuereinrichtung SE geleitet, die den Impuls erfasst und auswertet. Pressure actuation of the microswitch ES provided voltage pulse is therefore also passed directly to the control device SE, which detects and evaluates the pulse.
Bei Erfassung eines solchen Spannungsimpulses prüft die Steuereinrichtung SE, ob bei der Druckbetätigung des Mikroschalters ES das Netzteil NT bereits aktiviert ist. Bei noch nicht aktiviertem Netzteil NT erkennt die Steuereinrichtung SE eine Einschaltbetätigung des Benutzers und steuert, wie oben beschrieben, mit dem Einschaltsignal Sein das Relais RE an. Bei bereits aktiviertem Netzteil NT erkennt die Steuereinrichtung SE in der Mikroschalter-Druckbetätigung eine Ausschaltbetätigung des Benutzers, so dass die Steuereinrichtung SE ein entsprechendes Ausschaltsignal Saus zum Relais RE leitet. In diesem Fall wird die Haushalts-Geschirrspülmaschine außer Betrieb gesetzt. Ein gegebenenfalls gerade laufendes Spülprogramm wird somit unterbrochen. Upon detection of such a voltage pulse, the control device SE checks whether the power supply NT is already activated during the pressure actuation of the microswitch ES. When not activated, power supply PS, the controller SE detects a turning-on operation of the user, and controls, as described above, with the switch-S on the relay RE to. When already activated power supply NT recognizes the controller SE in the micro-switch pressure actuation a switch off operation of the user, so that the control device SE a corresponding switch-off signal S out to the relay RE. In this case, the household dishwasher is put out of action. An optionally currently running wash program is thus interrupted.
