Description

Die Erfindung betrifft ein Haushaltsgerät, insbesondere eine Haushalts-Geschirrspülmaschine, wenigstens aufweisend eine Übertragungsschnittstelle, die mit einem externen Anzeigemittel in Signalverbindung bringbar ist.The invention relates to a household appliance, in particular a domestic dishwasher, at least comprising a transmission interface, which can be brought into signal connection with an external display means.

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 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. Die DE 10 2007 058382 A1 offenbart eine Geschirrspülmaschine, mit einer Steuereinrichtung, die bei einer Betätigung eines Bedienelements des Haushaltsgeräts zumindest ein Anzeigeelement zur Anzeige eines Betriebszustands und/oder sonstiger Daten mit elektrischer Energie versorgt, welche Steuereinrichtung nach einer vorgegebenen Zeitdauer die Energieversorgung zum Anzeigeelement reduziert oder unterbricht. Das elektrische Haushaltgerät der DE 102 36 937 A1 weist eine Einrichtung zum Steuern von Gerätefunktionen und eine Einrichtung zum Kommunizieren mit einer Benutzungsperson auf. Dabei ist an dem Haushaltgerät ein Bewegungsmelder angeordnet und mit der Einrichtung zum Steuern und/oder der Einrichtung zum Kommunizieren wirkverbunden. Die Einrichtung zum Kommunizieren ist nur bei Erhalt eines Signals vom Bewegungsmelder wirksam schaltbar.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. Domestic 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 treatment process according to a program can be displayed 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. The DE 10 2007 058382 A1 discloses a dishwasher, with a control device which supplies at least one display element for displaying an operating state and / or other data with electrical energy upon actuation of a control element of the household appliance, which control device reduces or interrupts the power supply to the display element after a predetermined period of time. The household electrical appliance of DE 102 36 937 A1 has a device for controlling device functions and a device for communicating with a user. In this case, a motion detector is arranged on the household appliance and operatively connected to the device for controlling and / or the device for communicating. The device for communicating can be effectively switched only upon receipt of a signal from the motion detector.

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 household appliance, in particular household dishwasher, in which the energy consumption is further reduced.

Erfindungsgemäß ist vorgesehen, dass nach Abschluss eines Behandlungsvorganges das Haushaltsgerät von einem das Haushaltsgerät mit elektrischer Energie versorgenden Stromversorgungsnetz getrennt ist, und vor dem Trennen des Haushaltsgerät vom dem Stromversorgungsnetz, insbesondere zeitnah dem Abschluss des Behandlungsvorgangs, ein Signal über die Übertragungsschnittstelle zum Aktivieren des externen Anzeigemittels übertragbar ist zum Anzeigen von zumindest dem Ende des Behandlungsvorgangs. Dabei sind zum Trennen des Haushaltsgerät vom Stromversorgungsnetz entsprechende Schaltmittel vorgesehen, die das Haushaltsgerät selbsttätig, d.h. ohne Eingriff eines Benutzers vom Versorgungsnetz trennen, so dass das Haushaltsgerät ausgeschaltet ist und insbesondere keine Stand-by-Verluste mehr auftreten. Hierzu kann bspw. das Schaltmittel eine Selbsthaltekontaktschaltung aufweisen. Bevor das Schaltmittel auf einen Abschluss eines Behandlungsvorgangs hin die Trennung vom Versorgungsnetz bewirkt, wird z.B. von einer Steuerung des Haushaltsgeräts ein Signal erzeugt, das über dieAccording to the invention it is provided that after completion of a treatment process, the household appliance is separated from a household appliance with electrical power supply network, and before disconnecting the household appliance from the power supply network, in particular promptly completion of the treatment process, a signal via the transmission interface for activating the external display means is transmittable to indicate at least the end of the treatment process. In this case, corresponding to the separation of the household appliance from the power supply network Switching means provided which separate the household appliance automatically, ie without intervention of a user from the power supply, so that the household appliance is turned off and in particular no stand-by losses occur more. For this purpose, for example, the switching means may have a self-holding contact circuit. Before the switching means causes the completion of a treatment process towards the separation from the supply network, a signal is generated, for example, by a control of the household appliance, via the

Übertragungsschnittstelle übertragen werden soll, um eine externes Anzeigemittel zu aktivieren. Dies kann zeitnah zum Zeitpunkt des Abschlusses des Behandlungsvorgangs erfolgen, d.h. bspw. vor oder auch nach dem Abschluss des Behandlungsvorgangs. So kann nach Abschluss des Behandlungsvorgangs die Trennung vom Versorgungsnetz bspw. um eine Zeitdauer von 1 Sekunden bis zu 1 Minute verzögert werden, um in diese Zeitspanne das Signal zu erzeugen und über die Übertragungsschnittstelle zu übertragen. Es kann aber auch nahezu zeitgleich mit Abschluss des Behandlungsvorgangs erfolgen oder auch in einem Zeitraum von z.B. 1 Sekunde bis zu 5 Minuten vor Abschluss des Behandlungsvorgangs. In diesen beiden Fällen reduziert sich der Energieverbrauch um den Betrag, der in der o.g. Zeitdauer anfällt. Ferner ist in diesem Fall vorteilhaft, dass eine Bedienperson durch den zeitlichen Vorlauf derart rechtzeitig von dem Abschluss eines Behandlungsvorgangs informiert wird, dass sie sich zum Haushaltsgerät begeben kann, dass sich bspw. in einem anderen Raum einer Wohnung oder Hauses befindet, wobei in diesem Fall das externe Anzeigemittel dazu verwendet wird, das Haushaltsgerät betreffende Informationen an andere Orte zu übertragen. Das externe Anzeigemittel kann beispielhaft ein Display an einem Herd, einem Kühlschrank und/oder einem Radiogerät sein. Die Signalverbindung zwischen der Übertragungsschnittstelle des Haushaltsgerätes und dem externen Anzeigemittel kann zum Beispiel per Funk, WLAN, Bluetooth, Powerline, etc. erfolgen. Mittels der Übertragungsschnittstelle des Haushaltsgerätes wird zum Ende des Behandlungsvorganges das externe Anzeigemittel zur Anzeige von zumindest dem Ende des Behandlungsvorganges aktiviert. Da erfindungsgemäß das Ende des Behandlungsvorganges am externen Anzeigemittel angezeigt wird, erübrigt sich die Anzeige eines abgeschlossenen Behandlungsvorganges unmittelbar am Haushaltsgerät.Transmission interface to be transmitted to activate an external display means. This can be done promptly at the time of completion of the treatment procedure, i. for example, before or even after the completion of the treatment process. Thus, after completion of the treatment process, the disconnection from the supply network can be delayed, for example, by a period of 1 second to 1 minute in order to generate the signal in this time span and to transmit it via the transmission interface. However, it can also take place almost simultaneously with completion of the treatment process or even in a period of e.g. 1 second to 5 minutes before completion of treatment. In these two cases, the energy consumption is reduced by the amount that is in the o.g. Time is incurred. Furthermore, it is advantageous in this case that an operator is informed by the lead time in such a timely manner from the conclusion of a treatment process that they can go to the household appliance that is, for example, in another room of a flat or house, in which case the external display means is used to transfer information concerning the household appliance to other places. The external display means may be, for example, a display on a stove, a refrigerator and / or a radio. The signal connection between the transmission interface of the household appliance and the external display means can be done for example by radio, WLAN, Bluetooth, Powerline, etc. By means of the transmission interface of the household appliance, the external display means is activated to display at least the end of the treatment process at the end of the treatment process. Since according to the invention, the end of the treatment process is displayed on the external display means, the display of a completed treatment process is unnecessary directly on the household appliance.

Der Erfindung liegen Untersuchungen zugrunde, wonach eine Zeitdauer zwischen dem Abschluss des eigentlichen Behandlungsvorgangs und einem darauffolgenden Behandlungsvorgang im Bereich von Stunden oder Tagen liegen kann. Für den Fall, dass nach dem Ende des Behandlungsvorganges der Hauptschalter nicht ausgeschaltet wird, bleiben daher insbesondere die optischen Anzeigemittel, die das Programmende anzeigen, bis zum folgenden Behandlungsvorgang aktiviert. Dadurch kann in der Jahresenergiebilanz der Energieverbrauch des Haushaltsgerätes merklich erhöht sein. Die Erfindung ist insbesondere bei einem Haushaltsgerät anwendbar, das nach dem Ende des Behandlungsvorganges sowie insbesondere nach bereits erfolgter Aktivierung des externen Anzeigemittels automatisch außer Betrieb gesetzt wird, um einen Energieverbrauch des Haushaltsgerätes nach Beendigung des Behandlungsvorganges zu unterbinden.The invention is based on investigations, according to which a period of time between the conclusion of the actual treatment process and a 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, in particular the optical display means indicating the end of the program, remain activated until the subsequent treatment process. As a result, the energy consumption of the household appliance can be markedly increased in the annual energy balance. The invention is particularly applicable to a household appliance, which is set automatically after the end of the treatment process and in particular after already successful activation of the external display means out of order to prevent energy consumption of the household appliance after completion of the treatment process.

Bei einer solchen vollständigen Abschaltung des Haushaltsgerätes würde der Benutzer vom Haushaltsgerät selbst keinerlei Informationen darüber erhalten, ob das Haushaltsgerät den Behandlungsvorgang einwandfrei beendet hat, oder ob ein Stromausfall oder ein sonstiger Defekt vorliegt. Erfindungsgemäß wird daher das externe Anzeigemittel unmittelbar vor einer solchen Abschaltung des Haushaltsgerätes aktiviert, so dass bei vom Stromversorgungsnetz genommenen Haushaltsgerät am externen Anzeigemittel das Ende des Behandlungsvorganges anzeigbar ist.In such a complete shutdown of the household appliance, the user would receive no information from the household appliance itself, whether the appliance has completed the treatment process properly, or if there is a power failure or other defect. According to the invention, therefore, the external display means is activated immediately before such a shutdown of the household appliance, so that when taken from the power supply household appliance on the external display means the end of the treatment process can be displayed.

Zur Reduzierung des Energieverbrauches des externen Anzeigemittels kann dieses während des Behandlungsvorganges oder davor deaktiviert sein und erst bei entsprechender Ansteuerung durch das Haushaltsgerät aktiviert werden. Im Gegenzug kann das Haushaltsgerät über optische Anzeigemittel verfügen, die lediglich Betriebszustände vor und während des Behandlungsvorganges anzeigen, jedoch nicht das Ende des Behandlungsvorgangs anzeigen. Entsprechend kann die optische Betriebsanzeige nach dem Ende des Behandlungsvorganges deaktiviert sein.To reduce the energy consumption of the external display means this can be disabled during the treatment process or before and activated only with appropriate control by the household appliance. In turn, the home appliance may have visual indicators that merely indicate operating conditions before and during the treatment process, but do not indicate the end of the treatment process. Accordingly, the optical status indicator can be deactivated after the end of the treatment process.

Das externe Anzeigemittel kann nach dem Ende des Behandlungsvorganges für eine vorbestimmte Zeitdauer oder bis zu einer Ansteuerung mit einem Triggersignal aktiviert bleiben. Nach Ablauf dieser Zeitdauer kann das externe Anzeigemittel selbsttätig deaktiviert werden.The external display means may remain activated after the end of the treatment process for a predetermined period of time or until actuation with a trigger signal. After this period of time, the external display means can be automatically deactivated.

Alternativ oder zusätzlich dazu kann die Steuerung des Haushaltsgerätes zum Beispiel eine Gerätetür-Öffnung erfassen. In einem solchen Fall erkennt die Steuerung des Haushaltsgerätes, dass der Benutzer über das Ende des Behandlungsvorganges informiert ist. Die Steuerung kann in diesem Fall ein Triggersignal erzeugen, mit dem über die Übertragungsschnittstelle das externe Anzeigemittel deaktiviert wird. Bei Anwendung eines solchen Triggersignals zum Abschalten der externen Anzeigemittel bleibt die Steuereinrichtung des Haushaltsgeräts nach einem Programmende aktiviert, während lediglich die optischen Anzeigemittel deaktiviert werden.Alternatively or additionally, the control of the household appliance may detect, for example, a door of a appliance door. In such a case, the controller of the household appliance recognizes that the user is informed of the end of the treatment process. In this case, the controller can generate a trigger signal with which the external display means is deactivated via the transmission interface. When using such a trigger signal to switch off the external display means, the control device remains of the household appliance after a program end is activated, while only the optical display means are deactivated.

Das externe Anzeigemittel kann wie folgt aktiviert werden und das Programmende des Haushaltsgeräts anzeigen: So kann zum Ende des Behandlungsvorgangs eine Steuereinrichtung ein Programmende-Signal generieren, mit dem über die Übertragungsschnittstelle das externe Anzeigemittel angesteuert wird. Zusammen mit der Generierung des Programmende-Signals kann die Steuereinrichtung automatisch ein Ausschaltsignal erzeugen, mit dem wenigstens die in der Bedienblende des Haushaltsgeräts angeordneten optischen Anzeigemittel selbsttätig deaktiviert werden.The external display means can be activated as follows and indicate the program end of the household appliance: Thus, at the end of the treatment process, a control device can generate a program end signal with which the external display means is activated via the transmission interface. Together with the generation of the program end signal, the control device can automatically generate a switch-off signal with which at least the optical display means arranged in the control panel of the household appliance are automatically deactivated.

In einer energiesparenden Ausführungsform kann die Steuerung des Haushaltsgeräts eine Selbsthaltekontaktschaltung aufweisen. Die Selbsthaltekontaktschaltung kann durch das Ausschaltsignal deaktiviert werden und ein Schaltglied öffnen, mit dem ein Netzteil des Haushaltsgerätes stromlos schaltbar ist.In an energy-saving embodiment, the controller of the household appliance may have a self-holding contact circuit. The self-holding contact circuit can be deactivated by the switch-off signal and open a switching element with which a power supply unit of the household appliance can be switched without current.

Die Selbsthaltekontaktschaltung kann wenigstens einen Einschalter aufweisen. Dieser kann als Drucktaster ausgeführt sein, der im unbetätigten Zustand geöffnet ist und bei Betätigung elektrische Kontaktstellen schließt. Der Drucktaster kann als Mikroschalter in der Bedienblende des Haushaltsgerätes von einer Bedienperson betätigt werden und kann zum oben genannten Schaltglied parallel geschaltet sein.The self-holding contact circuit may have at least one power switch. This can be designed as a pushbutton, which is open in the unactuated state and closes electrical contact points when actuated. The push-button can be actuated as a microswitch in the control panel of the household appliance by an operator and can be connected in parallel to the above-mentioned switching element.

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 Schaltglied in einer Stromversorgungsleitung 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 ist.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 a switching element in a power supply line of the household appliance. Provided 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 decoupled from the mains.

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 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 Stromversorgung in das Haushaltsgerät unterbrochen ist.Furthermore, it is preferably provided that the power switch and a circuit breaker are arranged in parallel. The power supply network can eg at a microswitch trained switch and abut parallel to the switching element connected. 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 to the self-holding contact circuit, so that the switching element remains stable 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 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 supplied with the switch-off signal, it switches the relay contact from a stable currentless open state into stable de-energized closed state or vice versa, whereby the household appliance is completely decoupled from the network or connected to it. 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.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.

Ferner wird die Aufgabe der Erfindung durch ein Verfahren gemäß Patentanspruch 8 gelöst. Vorteilhaft Weiterbildungen sind in den Unteransprüchen angegeben.Furthermore, the object of the invention is achieved by a method according to claim 8. Advantageous developments are specified in the subclaims.

Nachfolgend ist ein Ausführungsbeispiel der Erfindung anhand der beigefügten Figuren beschrieben.Hereinafter, an embodiment of the invention with reference to the accompanying figures will be described.

Show it:
Fig. 1
in a schematic perspective view of a household appliance network consisting of a domestic dishwasher and an extractor hood; and
Fig. 2
a circuit arrangement of the household dishwasher.

In der Fig. 1 ist ein Haushaltsgerätenetzwerk gezeigt, das im vorliegenden Ausführungsbeispiel eine Haushalts-Geschirrspülmaschine und eine Dunstabzugshaube DUH aufweist. Die Haushalts-Geschirrspülmaschine ist mit einer Übertragungsschnittstelle U ausgestattet, die in Signalverbindung mit einem optischen Anzeigemittel EA der Dunstabzugshaube DUH ist, wie es mit dem gestrichelten Pfeil SV angedeutet ist. Das Anzeigemittel EA der Dunstabzugshaube DUH kann etwa ein Display mit an sich bekannten 7-Segmentanzeigen sein. Wie später ausführlich beschrieben, kann das Anzeigemittel AE der Dunstabzugshaube DUH in Doppelfunktion sowohl Betriebsparameter der Dunstabzugshaube als auch ein Programmende nach einem abgelaufenen Spülgang der Haushalts-Geschirrspülmaschine anzeigen.In the Fig. 1 a domestic appliance network is shown, which has a domestic dishwasher and a hood DUH in the present embodiment. The domestic dishwasher is equipped with a transmission interface U, which is in signal communication with an optical display means EA of the hood DUH, as indicated by the dashed arrow SV. The display means EA of the hood DUH can be about a display with known 7-segment displays. As described in detail later, the display means AE of the hood DUH in double function can display both operating parameters of the hood and a program end after an expired rinse cycle of the household dishwasher.

Die Haushalts-Geschirrspülmaschine weist eine frontseitige Gerätetür GT auf, die in bekannter Weise um eine bodenseitige horizontale Schwenkachse schwenkbar ist und mit der eine Beschickungsöffnung des Spülraumes BR zum Be- und/oder Entladen geöffnet oder geschlossen werden kann. Die Beschickungsöffnung ist oben durch eine Bedienblende B begrenzt, die einen Mikrotaster ES sowie lediglich angedeutete optische Anzeigemittel AZ einer Betriebsanzeige BA trägt. Zusätzlich sind Eingabemittel E vorgesehen, mit denen Betriebsparameter für einen Spülgang der Haushalts-Geschirrspülmaschine eingebbar sind.The household dishwasher has a front door GT, which is pivotable about a bottom-side horizontal pivot axis in a known manner and with which a feed opening of the washing compartment BR can be opened or closed for loading and / or unloading. The feed opening is bounded above by a control panel B, which carries a micro-switch ES and only indicated optical display means AZ a power indicator BA. In addition, input means E are provided with which operating parameters for a rinse cycle of the domestic dishwasher can be entered.

Der in der Fig. 1 im linken Bereich der Bedienblende B vorgesehene Mikroschalter ES ist hier beispielhaft als Tastschalter ausgebildet. Bei einer Druckbetätigung des Mikroschalters ES kann die Haushalts-Geschirrspülmaschine in Betriebsbereitschaft geschaltet werden, während bei einer darauffolgenden Druckbetätigung die Haushalts-Geschirrspülmaschine vom Stromversorgungsnetz entkoppelt wird.The Indian Fig. 1 provided in the left area of the control panel B micro switch ES is exemplified here as a key switch. In a press of the microswitch ES, the household dishwasher can be switched to standby, while in a subsequent printing operation, the household dishwasher is decoupled from the power grid.

In der Fig. 2 ist eine Schaltungsanordnung dargestellt, in der unter anderem der Mikroschalter ES sowie die Betriebsanzeige BA integriert sind. In der gezeigten Schaltungsanordnung ist die Haushalts-Geschirrspülmaschine über eine Hauptversorgungsleitung H am Stromversorgungsnetz angeschlossen. In der Hauptversorgungsleitung H ist ein später beschriebenes Schaltglied AS sowie ein Netzteil NT in Reihe geschaltet.In the Fig. 2 a circuit arrangement is shown, in which inter alia, the micro switch ES and the operation indicator BA are integrated. In the circuit arrangement shown, the domestic dishwasher is connected to the power supply network via a main supply line H. 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 geschalteten Reglers RG in eine Niederspannung von 5 V umgewandelt, mit der eine Steuereinrichtung SE versorgt wird. Das Netzteil NT versorgt außerdem über zusätzliche Ausgänge weitere Gerätekomponenten und auch die Betriebsanzeige BA der Haushalts-Geschirrspülmaschine mit Niederspannung.The 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 NT, with which a control device SE is supplied. The power supply unit NT also supplies additional device components via additional outputs and also the operating indicator BA of the household dishwasher with low voltage.

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.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 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. Die Steuereinrichtung SE der Haushalts-Geschirrspülmaschine ist unter Zwischenschaltung der Übertragungsschnittstelle U in Signalverbindung SV mit dem optischen Anzeigemittel EA der Dunstabzugshaube DUH, das hier als externes Anzeigemittel auch der Haushalts-Geschirrspülmaschine zugeordnet ist. Die Signalverbindung SV zwischen der Übertragungsschnittstelle U der Haushalts-Geschirrspülmaschine und dem externen Anzeigemittel EA kann hier beispielhaft eine Funkverbindung sein.Like from the Fig. 2 Furthermore, 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 assigned as a relay contact the aforementioned switching element AS, which is connected instead of a mechanical main switch in the main supply line H and as such assumes a main switch function with which the domestic dishwasher can be decoupled from the power supply network or connected. The control device SE of the domestic dishwasher is with the interposition of the transmission interface U in signal communication SV with the optical display means EA of the hood DUH, which is assigned here as an external display means and the household dishwasher. The signal connection SV between the transmission interface U of the domestic dishwasher and the external display means EA can be a radio connection by way of example here.

Der Steuereinrichtung SE ist außerdem ein Türöffnungssensor TS zugeordnet, der einen Schließ- oder Öffnungszustand der Gerätetür GT erfassen und an die Steuereinrichtung SE weiterleiten kann.The control device SE is also associated with a door opening sensor TS, which can detect a closing or opening state of the appliance door GT and forward it to the control device SE.

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 die Druckbetätigung des Mikroschalters ES wird ein Spannungsimpuls betreitgestelltt, der über das Netzteil NT und über den Regler RG zur Steuereinrichtung SE geleitet wird.When 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 pressure actuation of the microswitch ES a voltage pulse is betreitgestelltt, which is passed via the power supply unit NT and the controller RG to the control device SE.

Die Steuereinrichtung SE leitet daraufhin ein Einschaltsignal Sein 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.The control unit SE then forwards a switch S to a further the bistable relay RE, after which the relay coil is energized and the switching member is moved from the AS normally stable open state into a normally stable 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 und insbesondere deren Betriebsanzeige BA ist somit betriebsbereit geschaltet, so dass nachfolgend mittels der Eingabemittel E ein Spülprogramm gestartet werden kann. Während des Spülprogramms sowie vor dem Start des Spülprogramms können die optischen Anzeigemittel AZ der Haushalts-Geschirrspülmaschine den Betriebszustand sowie eingestellte Parameter anzeigen. Das mit Bezug auf die Haushalts-Geschirrspülmaschine externe Anzeigemittel EA der Dunstabzugshaube DUH kann demgegenüber unabhängig von der Haushalts-Geschirrspülmaschine arbeiten. Nach dem Ende des Spülprogramms schaltet die Steuereinrichtung SE die Gerätekomponenten, etwa Laugen- oder Umwälzpumpe, aus.The household dishwasher and in particular its operating display BA is thus switched to ready, so that subsequently by means of the input means E a Rinse program can be started. During the wash program, as well as before the start of the wash program, the optical display means AZ of the domestic dishwasher can display the operating status as well as set parameters. In contrast, the external display means EA of the extractor hood DUH with respect to the domestic dishwasher can operate independently of the domestic dishwasher. After the end of the washing program, the control device SE switches off the device components, such as a lye pump or a circulating pump.

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 Haushalts-Geschirrspülmaschine vollständig vom Stromversorgungsnetz getrennt ist.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. Subsequently, the relay RE switches the switching element AS from the closed position to the open position, whereby the household dishwasher is completely disconnected from the power supply network.

Folgerichtig sind daher auch die optischen Anzeigemittel AZ der Haushalts-Geschirrspülmaschine außer Betrieb gesetzt. 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 Programmende insbesondere auch eine Stromversorgung über das Netzteil NT zu dem optischen Anzeigemittel AZ der Betriebsanzeige BA unterbrochen ist.Consequently, therefore, the optical display means AZ of the domestic dishwasher are disabled. 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 end of the program in particular a power supply via the power supply unit NT is interrupted to the optical display means AZ of the power indicator BA.

Gleichzeitig mit dem Erzeugen des Ausschaltsignals Saus generiert die Steuereinrichtung SE ein Programmende-Signal SEnde, das mittels der Übertragungsschnittstelle U zum Anzeigemittel EA der Dunstabzugshaube DUH geleitet wird. In diesem Fall zeigt das Anzeigemittel EA beispielsweise zeitlich begrenzt das Programmende der Haushalts-Geschirrspülmaschine an, während die Haushalts-Geschirrspülmaschine bereits vollständig vom Stromversorgungsnetz entkoppelt ist.Simultaneously with the generation of the switch-off signal S out , the control device SE generates a program end signal S end , which is conducted by means of the transmission interface U to the display means EA of the extractor hood DUH. In this case, the display means EA displays, for example, the program end of the household dishwasher for a limited time, while the household dishwasher is already completely decoupled from the power supply network.

Zusätzlich oder alternativ zu einer solchen zeitlich begrenzten Programmende-Anzeige kann die Steuereinrichtung SE bei Erfassen einer Öffnungsbetätigung der Gerätetür GT, das externe Anzeigemittel EA mit einem Triggersignal ansteuern, um die Programmende-Anzeige zu deaktivieren. Hierzu ist in Abwandlung zur Schaltungsanordnung der Fig. 2 beispielhaft der Ausschalter AS nicht in der Hauptversorgungsleitung H angeordnet, sondern zwischen dem Netzteil NT und der Betriebsanzeige BA der Haushalts-Geschirrspülmaschine. Dadurch kann die Steuereinrichtung SE nach dem Programmende die externen Anzeigemittel EA der Dunstabzugshaube DUH mit dem Triggersignal ansteuern, um ein Abschalten der externen Anzeigemittel EA zu bewirken.In addition to or as an alternative to such a limited program end display, upon detection of an opening operation of the appliance door GT, the control device SE can trigger the external display means EA with a trigger signal at the program end display to disable. For this purpose, in a modification of the circuit arrangement of Fig. 2 by way of example, the circuit breaker AS is not arranged in the main supply line H, but between the power supply NT and the operating display BA of the household dishwasher. As a result, the control device SE can control the external display means EA of the extractor hood DUH with the trigger signal after the end of the program in order to effect a shutdown of the external display means EA.

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 manuellen Druckbetätigung des Mikroschalters ES bereitgestellte Spannungsimpuls wird daher auch unmittelbar bis zur Steuereinrichtung SE geleitet, die den Impuls erfasst und auswertet.Like from the Fig. 2 Furthermore, the microswitch ES is in signal connection via an input line EL directly to the control device SE. The voltage pulse provided by a manual pressure actuation of the microswitch ES is therefore also conducted 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 the power supply unit NT has not yet been activated, the control device SE detects a switch-on operation of the user and, as described above, controls the switch RE with the switch-on signal Sein. When already activated power supply NT recognizes the controller SE in the microswitch pressure actuation a shutdown of the user, so that the controller 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.
