Fig. 1 zeigt als Ausführungsbeispiel für ein Haushaltsgerät eine Geschirrspülmaschine mit einer frontseitigen Bedienblende 1. In der Bedienblende 1 sind in etwa mittig drei Programmschalter 3, 5, 7 zur Auswahl unterschiedlicher Spülprogramme vorgesehen. Die Geschirrspülmaschine weist außerdem eine Anzeigeeinheit 9 auf, die beispielhaft eine Tageszeit sowie eine Spülprogrammdauer anzeigen kann. Die Anzeigeeinheit 9 kann beispielhaft vier, mittels einer Steuereinrichtung ansteuerbare Sieben-Segment-Anzeigen aufweisen. In bekannter Weise ist in der Bedienblende 1 der Geschirrspülmaschine weiterhin ein Hauptschalter 11 zum Ein- und Ausschalten vorgesehen, der die Geschirrspülmaschine von einer Netzspannung des elektrischen Versorgungsnetzes trennt oder diese zuschaltet. Die in der Fig. 1 gezeigte Geschirrspülmaschine ist außerdem mit einer Zeitvorwahlfunktion ausgestattet, mittels der eine Zeitdauer Δtv benutzerseitig einstellbar ist. Erst nach Ablauf dieser benutzerseitig eingestellten Zeitdauer Δtv erfolgt der eigentliche Betriebsstart der Geschirrspülmaschine, so dass während dieser Zeitdauer Δtv die Geschirrspülmaschine sich bei eingeschaltetem Hauptschalter 11 im Standby-Modus befindet. Die Zeitdauer Δtv kann mittels der in der Fig. 1 unterhalb der Anzeigeeinheit 9 angedeuteten Bedienelemente 13 eingestellt werden.As an exemplary embodiment of a household appliance, FIG. 1 shows a dishwasher with a front control panel 1. In the control panel 1, three program switches 3, 5, 7 for selecting different washing programs are provided approximately in the middle. The dishwasher also has a display unit 9, which can display an example of a daytime and a Spülprogrammdauer. By way of example, the display unit 9 can have four sieve-segment displays which can be activated by means of a control device. In a known manner, a main switch 11 for switching on and off is further provided in the control panel 1 of the dishwasher, which separates the dishwasher from a mains voltage of the electrical supply network or this connects. The dishwasher shown in FIG. 1 is also equipped with a time preselection function by means of which a time duration Δt v can be set by the user. Only after expiration of this user-set time duration Δt v , the actual start of operation of the dishwasher, so that during this period .DELTA.t v, the dishwasher is in standby mode when the main switch 11 is turned on. The time duration Δt v can be set by means of the control elements 13 indicated in FIG.
Fig. 2 zeigt ein stark vereinfachtes Prinzipschaltbild eines ersten Ausführungsbeispiels der Steuereinrichtung 8 der Geschirrspülmaschine. Die Steuereinrichtung 8 ist über ein Netzteil 15 mit dem elektrischen Versorgungsnetz 17 verbunden, und zwar unter Zwischenschaltung des Hauptschalters 11 , über den die Geschirrspülmaschine vom elektrischen Versorgungsnetz 17 trennbar ist oder entsprechend zuschaltbar ist. Über das Netzteil 15 werden in bekannter Weise die Gerätekomponenten der Geschirrspülmaschine mit geeigneten Gleich- oder Wechselspannungen versorgt. Beispielhaft ist die Anzeigeeinheit 9 mit einer Versorgungsleitung 19 verbunden.2 shows a greatly simplified block diagram of a first embodiment of the control device 8 of the dishwasher. The control device 8 is connected via a power supply 15 to the electrical supply network 17, with the interposition of the main switch 11, via which the dishwasher from the electrical supply network 17 is separable or can be switched on accordingly. About the power supply 15, the device components of the dishwasher are supplied with suitable DC or AC voltages in a known manner. 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 control and / or display electronic component serves as an input unit for program input by means of the program switch 3, 5, 7 and the actuating elements 13, of which in FIG. 2, for example only, an actuator 13 is shown with the time Δt 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. In der vom Netzteil 15 zum Steuerelektronikbauteil 23 geführten Versorgungsleitung 27 ist als ein Schaltmittel 31 ein Schalter vorgesehen, die zweite Bauteilgruppe 23,23 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 das mit reduziertem Energiebedarf arbeitende erste Bauteilgruppe 21 zugeschaltet ist.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 the guided from the power supply 15 to the control electronics component 23 supply line 27 is provided as a switching means 31, a switch, the second component group 23,23 from the power supply 15 and the power supply 17 separate and thus switch off or can connect to it. 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 expiry of the preset period of time Δtv, the second component group 23, which normally operates with increased energy demand in standby mode, can be de-energized while 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.As is further apparent from FIG. 2, the switching means 31 is connected to the second component group 23 via a signal line 35. 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.FIG. 3 shows, according to the second exemplary embodiment, a further block diagram of the control device 8 of the dishwasher. The structure and operation of the control device 8 shown therein is substantially identical to the embodiment shown in FIG. 2. 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 die zweite 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 connection 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, the second component group 23 can also be generated a corresponding signal and passed to the second switching means 11, the entire Dishwasher from the house-side supply network 17 separates. As a result, energy losses can be completely avoided after the program has been completed.
