Description

Die Erfindung geht aus von einer Hausgerätevorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a household appliance device according to the preamble of claim 1.

Es sind Hausgeräte mit Hausgerätevorrichtungen bekannt, die einen Mikroprozessor aufweisen, der dazu vorgesehen ist, sich selbst in einen Stand-by-Modus zu versetzen, um den Energieverbrauch zu reduzieren.Domestic appliances are known with home appliance devices having a microprocessor designed to place itself in a stand-by mode to reduce power consumption.

Die Aufgabe der Erfindung besteht insbesondere darin, eine gattungsgemäße Hausgerätevorrichtung bereitzustellen, mit der der Energieverbrauch weiter reduzierbar ist. Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst, während vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung den Nebenansprüchen und Unteransprüchen entnommen werden können.The object of the invention is, in particular, to provide a generic household appliance device with which the energy consumption can be further reduced. The object is achieved by the features of claim 1, while advantageous embodiments and modifications of the invention, the dependent claims and claims can be removed.

Die Erfindung geht aus von einer Hausgerätevorrichtung mit wenigstens einem Verbraucher, der dazu vorgesehen ist, in einen Stand-by-Modus versetzt zu werden.The invention relates to a household appliance device with at least one consumer, which is intended to be put into a stand-by mode.

Es wird vorgeschlagen, dass die Hausgerätevorrichtung eine Stelleinheit umfasst, die dazu vorgesehen ist, zumindest teilweise unabhängig von einer Energieversorgung den Verbraucher in wenigstens einen Energiesparmodus zu versetzen, in dem der Verbraucher gegenüber im Stand-by-Modus einen geringeren Energieverbrauch aufweist. Dabei soll unter einem "Stand-by-Modus" jeder dem Fachmann als sinnvoll erscheinende Bereitschaftsmodus verstanden werden, beispielsweise ein Modus, in dem Schutzprogramme ablaufen, und insbesondere ein Modus, in dem bereits der Energieverbrauch gegenüber einem Betriebsmodus reduziert ist, und zwar indem zumindest eine Komponente abgeschaltet oder deren Leistung reduziert ist usw. Unter dem "Energiesparmodus" soll insbesondere ein Modus verstanden werden, in dem durch Abschalten wenigstens einer Komponente und/oder durch Reduzierung der Leistung der Energieverbrauch des Verbrauchers unter den im Stand-by-Modus geführt ist. Dabei können auch mehrere verschiedene Energiesparmodi vorgesehen sein, die sich im Energieverbrauch und/oder auch in anderen Merkmalen unterscheiden können. Vorzugsweise ist die Stelleinheit auch dazu vorgesehen, den Verbraucher in den Stand-by-Modus zu versetzten, wodurch eine zusätzliche Stelleinheit eingespart werden kann. Grundsätzlich ist jedoch auch eine zusätzliche Stelleinheit denkbar. Unter "zumindest teilweise unabhängig von einer Energieversorgung" soll in diesem Zusammenhang insbesondere verstanden werden, dass zumindest ein bestimmter Energieversorgungszustand kein zwingendes Kriterium ist, dass der Verbraucher mittels der Stelleinheit in den Energiesparmodus versetzt wird. Ferner soll unter "vorgesehen" insbesondere besonders ausgestattet, ausgelegt und/oder programmiert verstanden werden. Durch die erfindungsgemäße Lösung kann der Energieverbrauch weiter reduziert werden.It is proposed that the home appliance device comprises an actuating unit which is provided to enable the consumer, at least partially independently of a power supply, to enter at least one energy-saving mode in which the consumer has a lower energy consumption in stand-by mode. Here, a "standby mode" is understood to mean any standby mode that the skilled person considers useful, for example a mode in which protection programs run, and in particular a mode in which the energy consumption is already reduced compared to an operating mode, namely by at least a component is switched off or its power is reduced, etc. The "energy saving mode" is to be understood in particular a mode in which by switching off at least one component and / or by reducing the power consumption of the consumer is performed under the stand-by mode , In this case, several different energy-saving modes may be provided, which may differ in energy consumption and / or in other features. Preferably, the actuator is also to provided to put the consumer in the stand-by mode, whereby an additional actuator can be saved. In principle, however, an additional control unit is conceivable. By "at least partially independent of a power supply" should be understood in this context, in particular, that at least one particular power state is not a mandatory criterion that the consumer is placed by means of the actuator in the energy saving mode. Furthermore, the term "provided" should be understood to mean in particular specially equipped, designed and / or programmed. The inventive solution, the energy consumption can be further reduced.

Umfasst die Stelleinheit wenigstens einen Prozessor, kann die Stellfunktion besonders einfach integriert werden. Die Stelleinheit kann jedoch auch durch andere, dem Fachmann als sinnvoll erscheinende Einheiten und insbesondere durch andere Verbraucher gebildet sein und kann insbesondere auch mehrere Untereinheiten aufweisen, die beispielsweise jeweils für unterschiedliche Verbraucher zuständig sind.If the setting unit comprises at least one processor, the setting function can be integrated particularly easily. However, the actuating unit can also be formed by other units that appear appropriate to the person skilled in the art, and in particular by other consumers, and in particular can also have a plurality of subunits, which are each responsible, for example, for different consumers.

In einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, dass der Verbraucher wenigstens einen Prozessor umfasst, wodurch große Einsparpotentiale erschlossen werden können. Dabei können der Verbraucher und die Stelleinheit zumindest teilweise einstückig ausgeführt sein.In a further embodiment of the invention it is proposed that the consumer comprises at least one processor, whereby large savings potentials can be developed. In this case, the consumer and the actuator may be at least partially made in one piece.

Ferner wird vorgeschlagen, dass die Stelleinheit dazu vorgesehen ist, wenigstens einen Verbraucher abweichend von wenigstens einem anderen Verbraucher, und zwar insbesondere in zeitlicher Hinsicht, in den Energiesparmodus zu versetzen, wodurch flexibel unterschiedliche Prioritäten berücksichtigt und insbesondere hohe Sicherheitsstandards gewährleistet werden können. Insbesondere können mittels einer entsprechenden Ausgestaltung Sicherheitseinheiten, wie beispielsweise eine Fehleranzeigeeinheit, eine Restwärmeanzeigeeinheit usw., gezielt erst nach Vorliegen eines bestimmten Betriebszustands bzw. nach Vorliegen bestimmter Parameter in den Energiesparmodus versetzt werden.It is also proposed that the setting unit is provided to put at least one consumer different from at least one other consumer, in particular in terms of time, in the energy-saving mode, which flexibly takes different priorities into account and in particular high security standards can be ensured. In particular, by means of a corresponding design, security units, such as an error display unit, a residual heat display unit, etc., can specifically be placed in the energy-saving mode only after the presence of a specific operating state or after the presence of certain parameters.

Ferner trägt zu einer hohen Sicherheit bei, wenn die Stelleinheit zur Berücksichtigung wenigstens einer Fehlerkenngröße vorgesehen ist. Bei Vorliegen einer Fehlerkenngröße kann insbesondere gezielt vermieden werden, dass ein oder mehrere Verbraucher in den Energiesparmodus versetzt werden.Furthermore, it contributes to a high level of security if the setting unit is provided to take account of at least one fault characteristic. In case of an error characteristic In particular, it can be purposefully avoided that one or more consumers are put into energy-saving mode.

In einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, dass die Stelleinheit dazu vorgesehen ist, wenigstens einen Verbraucher zumindest abhängig von einer temperaturabhängigen Kenngröße in den Energiesparmodus zu versetzen, wie insbesondere eine Restwärmeanzeigeeinheit usw., wodurch temperaturbedingte Risiken, und zwar insbesondere bei Gargeräten, gezielt berücksichtigt werden können.In a further embodiment of the invention it is proposed that the setting unit is provided to put at least one consumer at least dependent on a temperature-dependent characteristic in the energy saving mode, such as in particular a residual heat display unit, etc., whereby temperature-related risks, specifically in cooking appliances, specifically taken into account can be.

Umfasst die Hausgerätevorrichtung eine Stelleinheit, die dazu vorgesehen ist, nach wenigstens einer erkannten Energiesparmoduskenngröße zumindest einen Übertrag von Daten, wie beispielsweise eine Anzahl von Betriebsstunden, Daten über aufgetretene Fehler, Daten über Anwendergewohnheiten usw., von einem Speicher in einen anderen Speicher einzuleiten, können weitere Einsparpotentiale erschlossen werden, und zwar insbesondere, indem nach Übertrag der Daten die Energieversorgung für wenigstens einen flüchtigen Speicher, bei dem nach Abschaltung der Energieversorgung die darin gespeicherten Daten verloren sind, unterbrochen werden kann, ohne dass insgesamt Daten verloren gehen. Die Stelleinheit kann dabei getrennt oder einstückig mit der Stelleinheit ausgeführt sein, die dazu dient, die Verbraucher in den Energiesparmodus zu versetzen. Unter einer "Energiesparmoduskenngröße" soll insbesondere eine Kenngröße verstanden werden, die die Stelleinheit dazu veranlasst, den Verbraucher in den Energiesparmodus zu versetzen.The home appliance device comprises an actuator unit, which is provided to be able to initiate at least one transfer of data, such as a number of operating hours, data on errors that have occurred, data on user habits, etc., from one memory to another memory after at least one recognized energy-saving mode parameter Further savings potentials are opened, in particular by the power supply for at least one volatile memory, in which after switching off the power supply, the data stored therein can be interrupted after transfer of the data, without the total loss of data. The actuator can be carried out separately or in one piece with the actuator, which serves to put the consumer in the energy-saving mode. A "power-saving mode parameter" is to be understood in particular to mean a parameter that causes the actuator unit to put the load into the energy-saving mode.

Ferner wird vorgeschlagen, dass der Verbraucher neben wenigstens einer Datenleitung mit einer Signalleitung zumindest zur Aktivierung und/oder besonders vorteilhaft zur Deaktivierung des Energiesparmodus verbunden ist. Die Signalleitung kann gezielt auf die Anforderungen der Aktivierung und/oder insbesondere der Deaktivierung ausgelegt und es kann stets eine sichere Deaktivierung gewährleistet werden. Zudem kann die erfindungsgemäße Lösung durch eine entsprechende Ausgestaltung mit geringem Aufwand in ein bestehendes System integriert werden. Wird dagegen eine bereits vorliegende Datenleitung, vorzugsweise eine vorliegende Busleitung, zur Aktivierung und/oder Deaktivierung des Energiesparmodus genutzt, können zusätzliche Leitungen vermieden und Montageaufwand sowie Kosten können reduziert werden.Furthermore, it is proposed that the consumer is connected in addition to at least one data line with a signal line at least for activation and / or particularly advantageous for deactivating the energy-saving mode. The signal line can be designed specifically for the requirements of the activation and / or in particular the deactivation and it can always be ensured a safe deactivation. In addition, the solution according to the invention can be integrated by an appropriate design with little effort into an existing system. If, on the other hand, an already existing data line, preferably a present bus line, is used to activate and / or deactivate the energy-saving mode, additional lines can be avoided and assembly costs and costs can be reduced.

Umfasst die Hausgerätevorrichtung eine Stelleinheit, mittels der wenigstens eine Kenngröße des Energiesparmodus von einem Bediener einstellbar ist, kann die Flexibilität der Hausgerätevorrichtung gesteigert und dieselbe kann von einem Bediener gezielt auf seine Anforderungen abgestimmt werden. Die Stelleinheit kann dabei wiederum getrennt oder einstückig mit der Stelleinheit ausgeführt sein, die dazu dient, die Verbraucher in den Energiesparmodus zu versetzen. Unter einer "Kenngröße des Energiesparmodus" soll in diesem Zusammenhang sowohl eine Größe verstanden werden, die sich auf eine Voraussetzung des Energiesparmodus bezieht, beispielsweise nach welcher Zeit dieser aktiviert wird, als auch eine Größe, die eine Einstellung im Energiesparmodus selbst betrifft, beispielsweise inwieweit bestimmte Verbraucher und/oder welche Verbraucher im Energiesparmodus abgeschaltet und/oder in ihrer Leistung reduziert werden.If the domestic appliance device comprises an actuating unit, by means of which at least one parameter of the energy-saving mode can be set by an operator, the flexibility of the domestic appliance device can be increased and the same can be specifically tuned by an operator to his requirements. The actuating unit can in turn be implemented separately or in one piece with the control unit, which serves to put the consumers in the energy-saving mode. In this context, a "parameter of the energy-saving mode" should be understood to mean a quantity which relates to a precondition of the energy-saving mode, for example after which time it is activated, as well as a variable relating to a setting in the energy-saving mode itself, for example to what extent Consumers and / or which consumers are switched off in the energy-saving mode and / or reduced in their performance.

Die Signalleitung 28 dient zur Aktivierung und Deaktivierung eines erfindungsgemäßen Energiesparmodus.Consumers 10, 12, 14, 16, 18, memories 22, 24, and actuator 20 are connected to a central power supply unit 52 via a multi-branch power line 50. Furthermore, the consumers 10, 12, 14, 16, 18, the memories 22, 24 and the control unit 20 are interconnected via a data line 26 formed by a bus line and via a signal line 28. The signal line 28 serves to activate and deactivate a power saving mode according to the invention.

Die Stelleinheit 20 ist erfindungsgemäß dazu vorgesehen, unabhängig von einer Energieversorgung über die Energieversorgungseinheit 52, die Verbraucher 10, 12, 14, 16, 18 und insbesondere auch sich selbst in den Energiesparmodus zu versetzen, in dem die Verbraucher 10, 12, 14, 16, 18 und die Stelleinheit 20 gegenüber im Stand-by-Modus einen geringeren Energieverbrauch W aufweisen.According to the invention, the actuating unit 20 is provided to put the consumers 10, 12, 14, 16, 18 and in particular also themselves into the energy-saving mode independently of a power supply via the energy supply unit 52, in which the consumers 10, 12, 14, 16 , 18 and the control unit 20 have a lower energy consumption W compared to the stand-by mode.

Wird der Herd 54 von einem Bediener abgeschaltet und liegt eine Restwärme vor, versetzt die Stelleinheit 20 bis auf den von der Restwärmeanzeigeeinheit gebildeten Verbraucher 18 die Verbraucher 10, 12, 14, 16 mittels einem ersten Signal über die Signalleitung 28 und sich selbst nach einer von einem Bediener über die Bedieneinheit und über die Stelleinheit 20 einstellbaren ersten Zeitspanne t1 in den Stand-by-Modus (Figur 2 und 3). Im Stand-by-Modus ist bereits der Energieverbrauch W durch Reduzierung der Beleuchtung der Verbraucher 10, 12, 14 und durch Reduzierung der Taktfrequenz des von dem Mikroprozessor gebildeten Verbrauchers 16 und der Stelleinheit 20 gegenüber einem Betriebsmodus reduziert.If the oven 54 is switched off by an operator and there is residual heat, the actuator 20 displaces the consumers 10, 12, 14, 16 by means of a first signal via the signal line 28 and himself to one of the consumers 18 formed by the residual heat display unit an operator via the control unit and via the setting unit 20 adjustable first time period t 1 in the stand-by mode (Figure 2 and 3). In stand-by mode, the energy consumption W is already reduced by reducing the illumination of the load 10, 12, 14 and by reducing the clock frequency of the consumer reduced by the microprocessor 16 formed consumer and the actuator 20 to a mode of operation.

Nach einer von dem Bediener über die Bedieneinheit und über die Stelleinheit 20 einstellbaren, gegenüber der ersten Zeitspanne t1 größeren zweiten Zeitspanne t2 versetzt die Stelleinheit 20 bis auf den von der Restwärmeanzeigeeinheit gebildeten Verbraucher 18 die Verbraucher 10, 12, 14, 16 und die Speicher 22, 24 mittels einem zweiten Signal über die Signalleitung 28 und sich selbst in den Energiesparmodus. Im Energiesparmodus ist der Energieverbrauch W gegenüber dem Stand-by-Modus weiter reduziert, und zwar indem die Beleuchtungen der Verbraucher 10, 12, 14 vollständig abgeschaltet, der vom Display gebildete Verbraucher 10 und die Speicher 22, 24 vollständig von der Energieversorgungseinheit 52 abgekoppelt und die internen Rechenprozesse innerhalb des von dem Mikroprozessor gebildeten Verbrauchers 16 und der Stelleinheit 20 sowie deren Taktfrequenz auf ein Minimum reduziert sind. Bevor jedoch der Energiesparmodus aktiviert wird, leitet die Stelleinheit 20 nach Ablauf der zweiten Zeitspanne t2 bzw. nach einer den Ablauf der zweiten Zeitspanne t2 kennzeichnenden Energiesparmoduskenngröße einen Übertrag von Daten über die von der Busleitung gebildete Datenleitung 26 von dem flüchtigen Arbeitsspeicher 22 zu dem nichtflüchtigen Festwertspeicher 24 ein. Soll über die Uhr bzw. über den Verbraucher 14 die Uhrzeit ständig angezeigt werden, kann von dem Bediener eine Einstellung vorgenommen werden, dass der Verbraucher 14 stets in seinem Betriebsmodus verbleibt.After an adjustable by the operator via the control unit and the setting unit 20, compared to the first time period t 1 larger second time interval t 2 offset the actuator 20 except for the consumer 18 formed by the residual heat display consumer 10, 12, 14, 16 and Memory 22, 24 by means of a second signal via the signal line 28 and itself in the power saving mode. In the energy-saving mode, the energy consumption W compared to the stand-by mode is further reduced by the lights of the consumer 10, 12, 14 completely off, the consumer formed by the display 10 and the memory 22, 24 completely decoupled from the power supply unit 52 and the internal computing processes within the consumer 16 formed by the microprocessor 16 and the actuator 20 and their clock frequency are reduced to a minimum. However, before the energy-saving mode is activated, the actuator 20, after expiration of the second period of time t 2 or after the expiration of the second time period t 2 characterizing Energiesparmoduskenngröße directs a transfer of data via the bus line formed by the data line 26 from the volatile memory 22 to the non-volatile read-only memory 24. If the time is to be constantly displayed via the clock or via the consumer 14, an adjustment can be made by the operator that the consumer 14 always remains in his operating mode.

Von einer nicht näher dargestellten Sensoreinheit werden Temperaturwerte der Kochstellen 32, 34, 36, 38 sowie des Garraums 42 erfasst. Liegen sämtliche Temperaturwerte unter einem in Grenzen von dem Bediener einstellbaren Schwellwert, beispielsweise zu einem Zeitpunkt t3, wird der von der Restwärmeanzeigeeinheit gebildete Verbraucher 18 von der Stelleinheit 20 mittels einem Signal über die Signalleitung 28 ebenfalls in den Energiesparmodus versetzt, indem dieser von der Energieversorgungseinheit 52 entkoppelt wird. Liegen nach Ablauf der zweiten Zeitspanne t2 bereits sämtliche Temperaturwerte unter dem Schwellwert, wird der von der Restwärmeanzeigeeinheit gebildete Verbraucher 18 unmittelbar mit den Verbrauchern 10, 12, 14 und der Stelleinheit 20 in den Energiesparmodus versetzt.Temperature values of the hotplates 32, 34, 36, 38 and of the cooking chamber 42 are detected by a sensor unit (not shown). Are all temperature values below an adjustable within limits by the operator threshold value, for example, at a time t 3, the consumer formed by the residual heat display unit 18 of the actuator 20 is displaced also in the power saving mode by a signal on the signal line 28 by that of the power supply unit 52 is decoupled. If, after the second time interval t 2 , all the temperature values are already below the threshold value, the load 18 formed by the residual heat display unit is placed directly in the energy-saving mode with the consumers 10, 12, 14 and the setting unit 20.

Liegt eine Fehlerkenngröße vor, so dass ein Fehler in dem vom Display gebildeten Verbraucher 10 angezeigt wird, wird dies von der Stelleinheit 20 berücksichtigt und die Aktivierung des Energiesparmodus beim vom Display gebildeten Verbraucher 10 wird unterbunden, so dass der Fehler ständig angezeigt werden kann.If an error parameter is present, so that an error is displayed in the consumer 10 formed by the display, this is taken into account by the setting unit 20 and the activation of the energy-saving mode in the consumer 10 formed by the display is prevented, so that the error can be displayed continuously.

Wird vom Bediener bei aktiviertem Energiesparmodus die Bedieneinheit betätigt, wird von dieser bzw. vom Verbraucher 12 ein Signal über die Signalleitung 28 zur Stelleinheit 20 geleitet. Die Stelleinheit 20 wird dadurch in ihren Betriebsmodus versetzt und versetzt anschließend mittels einem Signal über die Signalleitung 28 die Verbraucher 10, 12, 14, 16, 18 sowie die Speicher 22, 24 in ihre Betriebsmodi.If the operating unit is actuated by the operator when the energy-saving mode is activated, a signal is passed from the latter or the consumer 12 via the signal line 28 to the setting unit 20. The adjusting unit 20 is thereby placed in its operating mode and then offset by means of a signal via the signal line 28, the consumer 10, 12, 14, 16, 18 and the memory 22, 24 in their operating modes.
