Description

Die Erfindung geht aus von einem Hausgerät nach dem Oberbegriff des Anspruchs 1 und von einem Verfahren zum Betreiben eines solchen Hausgeräts nach dem Oberbegriff des Anspruchs 12.The invention relates to a domestic appliance according to the preamble of claim 1 and to a method for operating such a domestic appliance according to the preamble of claim 12.

Aus dem Stand der Technik sind Hausgeräte bekannt, die Steuereinheiten zum Betreiben des Hausgeräts in verschiedenen Betriebsmodi umfassen. Mit der immer stärkeren Rechenleistung der verwendeten Steuereinheiten nehmen auch die Komplexität und die Vielfalt der zur Verfügung stehenden Betriebsmodi zu. Ferner umfassen Hausgeräte Bedienerschnittstellen mit Stellelementen zum Einstellen von Betriebsparametern des Hausgeräts. Die Stellelemente können als berührungsempfindliche Schalt- oder Stellelemente ausgebildet sein oder als bewegliche Schieber oder Drehknöpfe. In den verschiedenen Betriebsmodi unterscheiden sich die Wertebereiche der Betriebsparameter stark voneinander, so dass bei einer fest vorgegebenen Zuordnung zwischen den Zuständen des Stellelements und den Werten des Betriebsparameters verschiedene Schaltelemente für die verschiedenen Betriebsmodi verwendet werden müssen.Domestic appliances are known from the prior art, which include control units for operating the domestic appliance in various operating modes. With the ever-increasing computing power of the control units used, the complexity and variety of operating modes available also increase. Furthermore, domestic appliances include operator interfaces with control elements for setting operating parameters of the domestic appliance. The adjusting elements can be designed as touch-sensitive switching or adjusting elements or as movable slides or knobs. In the various operating modes, the value ranges of the operating parameters differ greatly from one another, so that, given a fixed predefined association between the states of the actuating element and the values of the operating parameter, different switching elements must be used for the different operating modes.

Derartige Hausgeräte sind beispielsweise aus der EP 1273 851 A2 und der DE 10 2005 040346 A1 bekannt. Dort werden längliche Sensorstreifen als Stellelemente verwendet und jeweils Zuordnungsintervalle von Berührpunkten einem Betriebsparameter zugeordnet.Such household appliances are for example from the EP 1273 851 A2 and the DE 10 2005 040346 A1 known. There elongated sensor strips are used as adjusting elements and associated with each assignment intervals of touch points an operating parameter.

Die Aufgabe der Erfindung besteht insbesondere darin, ein gattungsgemäßes Hausgerät bzw. ein Verfahren zum Betreiben eines solchen Hausgeräts einfacher, kostengünstiger und benutzerfreundlicher zu gestalten und insbesondere eine große Vielfalt von Betriebsmodi ohne zusätzliche Schaltelemente zu ermöglichen, wobei insbesondere eine versehentliche Einstellung eines unerwünschten Betriebsparameters vermieden werden soll.The object of the invention is in particular to make a generic domestic appliance or a method for operating such a domestic appliance easier, cheaper and more user-friendly and in particular to allow a wide variety of operating modes without additional switching elements, in particular an accidental adjustment of an undesirable operating parameter can be avoided should.

Die Aufgabe wird erfindungsgemäß durch die Merkmale der Patentansprüche 1 und 12 gelöst, während vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung den Unteransprüchen entnommen werden können.The object is achieved by the features of claims 1 and 12, while advantageous embodiments and modifications of the invention can be taken from the dependent claims.

Die Erfindung geht aus von einem Hausgerät mit einer Steuereinheit zum Betreiben des Hausgeräts in verschiedenen Betriebsmodi und einer Bedienerschnittstelle, die ein Stellelement zum Einstellen eines Betriebsparameters umfasst, wobei die Steuereinheit dazu ausgelegt ist, eine Zuordnungsfunktion zu nutzen, um jedem Zustand des Stellelements einen Wert des Betriebsparameters zuzuordnen.The invention is based on a domestic appliance with a control unit for operating the domestic appliance in various operating modes and an operator interface, which comprises an actuating element for setting an operating parameter, the control unit for this purpose is designed to use an assignment function to assign a value of the operating parameter to each state of the control element.

Es wird vorgeschlagen, dass die Steuereinheit dazu ausgelegt ist, die Zuordnungsfunktion abhängig von einem Betriebsmodus zu bestimmen. Dadurch kann das Hausgerät mit ei- x nem und demselben Schaltelement in vielen verschiedenen Betriebsmodi gesteuert werden, so dass durch den Verzicht auf zusätzliche Schaltelemente Kosten eingespart werden können. Die Zuordnungsfunktion kann an den verwendeten Betriebsmodus angepasst werden, so dass jederzeit eine einfache und intuitive Bedienbarkeit des Hausgeräts gewährleistet werden kann.It is proposed that the control unit is designed to determine the allocation function depending on an operating mode. As a result, the domestic appliance can be controlled with an identical switching element in many different operating modes so that costs can be saved by dispensing with additional switching elements. The assignment function can be adapted to the operating mode used, so that at any time a simple and intuitive operation of the household appliance can be guaranteed.

Dabei ist gemäß der Erfindung das Stellelement als länglicher Sensorstreifen mit Sensorelementen zum Detektieren eines Berührungspunkts in einer Längsrichtung des Sensorstreifens, also als so genannter "Slider" oder "Glider" ausgelegt.In this case, according to the invention, the adjusting element is designed as an elongated sensor strip with sensor elements for detecting a contact point in a longitudinal direction of the sensor strip, that is to say as a so-called "slider" or "glider".

Die Zuordnungsfunktion ordnet erfindungsgemäß Berührpunkte in wenigstens einem Intervall von Berührpunkten einem Wert des Betriebsparameters zu.According to the invention, the assignment function assigns touch points in at least one interval of touch points to a value of the operating parameter.

Ferner sind erfindungsgemäß zumindest zwei Intervalle, die jeweils einem Wert des Betriebsparameters entsprechen, durch ein Zwischenintervall getrennt, wobei die Steuereinheit einen zuvor eingestellten Wert des Betriebsparameters beibehält, wenn eine Berührung in dem Zwischenintervall detektiert wird. Dadurch kann ein versehentliches Berühren eines benachbarten Zuordnungsintervalls vermieden werden.Furthermore, according to the invention, at least two intervals, each corresponding to a value of the operating parameter, are separated by an intermediate interval, wherein the control unit retains a previously set value of the operating parameter when a touch is detected in the intermediate interval. This can prevent accidental touching of an adjacent allocation interval.

Als Stellelemente kommen neben klassischen Drehknöpfen und Schiebem auch berührungsempfindliche Sensoren bzw. Sensorstreifen in Betracht, wobei der Zustand eines solchen Stellelements dann insbesondere durch den Ort und/oder die Dauer einer Berührung des Sensorstreifens gekennzeichnet sein kann. Der Sensorstreifen kann linear oder auch gebogen ausgebildet sein, insbesondere auch zu einem Kreis oder einem Kreisring geschlossen.In addition to classical knobs and pushes, touch-sensitive sensors or sensor strips are also possible as adjusting elements, the state of such an actuating element then being able to be characterized in particular by the location and / or duration of contact of the sensor strip. The sensor strip may be formed linear or curved, in particular closed to a circle or a circular ring.

In einer Weiterbildung der Erfindung wird vorgeschlagen dass das Stellelement zumindest einen berührungsempfindlichen Sensorbereich umfasst, und der Zustand des Stellelements durch einen Ort einer Berührung des Sensorbereichs durch einen Bediener bestimmt ist, so dass die Zuordnungsfunktion die Zustände mit einer Ortsauflösung auf eine endlichen Zahl von möglichen Werten des Betriebsparameters abbildet, wobei die Steuereinheit die Ortsauflösung insbesondere abhängig von dem Betriebsmodus bestimmen kann.In one development of the invention, it is proposed that the actuating element comprises at least one touch-sensitive sensor area, and the state of the actuating element is determined by a location of contact of the sensor area by an operator, so that the assignment function the states with a spatial resolution to a finite number of possible values the operating parameter, wherein the control unit can determine the spatial resolution, in particular depending on the operating mode.

Die Bedienung kann besonders intuitiv gestaltet werden, wenn die Bedienerschnittstelle Mittel zum Visualisieren der verwendeten Zuordnungsfunktion umfasst.The operation can be made particularly intuitive if the user interface comprises means for visualizing the assignment function used.

Beispielsweise können entlang des Sensorstreifens eine Reihe von Leuchtmitteln angeordnet sein, von denen in wenigstens einem Betriebsmodus eine Auswahl von Leuchtmitteln aktiviert wird. Als Leuchtmittel können beispielsweise Leuchtdioden verwendet werden, die auch hinter einer Blende angeordnet sein können oder mit einem Diffuser eine Hintergrundbeleuchtung des Stellelements erzeugen können. Die Anzahl der aktivierten Leuchtmittel ist dabei vorteilhaft eine lineare Funktion der Anzahl der möglichen Werte des Betriebsparameters. Die Positionen der aktivierten Leuchtmittel kann den Intervallen von Berührpunkten, die einem Wert des Betriebsparameters zugeordnet sind, entsprechen. Dazu können die aktivierten Leuchtmittel beispielsweise die Mitten und/oder die Endpunkte bzw. Zwischenintervalle dieser Intervalle markieren. Ferner ist es denkbar, die gesamte Fläche der Intervalle zu hinterleuchten.For example, along the sensor strip a number of lighting means may be arranged, of which in at least one operating mode a selection of lighting means is activated. Light-emitting diodes, for example, can be used as the light-emitting means, which can also be arranged behind a diaphragm or can generate a backlight of the actuating element with a diffuser. The number of activated illuminants is advantageously a linear function of the number of possible values of the operating parameter. The positions of the activated bulbs may correspond to the intervals of touch points associated with a value of the operating parameter. For this purpose, the activated lighting means may, for example, mark the centers and / or the end points or intermediate intervals of these intervals. Furthermore, it is conceivable to backlight the entire surface of the intervals.

Eine optische Rückmeldung kann ermöglicht werden, wenn die Bedienerschnittstelle ein Display zum Anzeigen eines eingestellten Werts des Betriebsparameters umfasst. Dadurch können Irrtümer über die vorgenommenen Einstellungen auf Seiten des Bedieners vermieden werden.Visual feedback may be enabled when the operator interface includes a display for displaying a set value of the operating parameter. This makes it possible to avoid errors on the settings made on the part of the operator.

Die Vorteile des Erfindungsgedankens kommen insbesondere dann zum Tragen, wenn das Hausgerät als Kochfeld ausgebildet ist, da in diesem Technischen Bereich die schnelle und intuitive Bedienbarkeit auch durch sehr unerfahrene Benutzer besonders wichtig ist.The advantages of the concept of the invention come into play, in particular, when the domestic appliance is designed as a hob, since in this technical field the fast and intuitive operability is also particularly important, even by very inexperienced users.

Insbesondere wenn das Kochfeld zumindest einen Sensor zum Messen der Temperatur eines auf das Kochfeld aufgestellten Kochgeschirrelements umfasst, ist eine große Vielfalt von verschiedenen Betriebsmodi sinnvoll realisierbar, und zwar insbesondere Betriebsmodi mit geregelter Heizleistung und ungeregelte Betriebsmodi. Es können dann eine Soll-Temperatur und/oder eine Soll-Heizleistung über das Stellelement eingestellt werden.In particular, when the hob comprises at least one sensor for measuring the temperature of a cooking utensil mounted on the hob, a wide variety of different operating modes can be meaningfully realized, in particular operating modes with regulated heating power and uncontrolled operating modes. It can then be set via the actuator a setpoint temperature and / or a desired heat output.

Beispielsweise kann in wenigstens einem Betriebszustand der Betriebsparameter eine Solltemperatur eines auf dem Kochfeld angeordneten Kochgeschirrelements sein, so dass der Bediener über das Stellelement unmittelbar die Solltemperatur einstellen kann, die dass von der Steuereinheit mit Hilfe des Temperatursensors eingeregelt wird.For example, in at least one operating state, the operating parameter may be a setpoint temperature of a cooking element arranged on the hob, so that the operator can directly set the desired temperature via the control element, which is regulated by the control unit with the aid of the temperature sensor.

Insbesondere kann die Ortsauflösung des Stellelements verändert werden, wenn die Steuereinheit die Zustände in einem ersten Betriebszustand auf eine erste Zahl von möglichen Werten des Betriebsparameters abbildet und die Zustände in einem zweiten Betriebszustand auf eine zweite Zahl von möglichen Werten des Betriebsparameters abbildet, wobei die erste Zahl und die zweite Zahl unterschiedlich sind.In particular, the spatial resolution of the actuating element can be changed when the control unit maps the states in a first operating state to a first number of possible values of the operating parameter and maps the states in a second operating state to a second number of possible values of the operating parameter, wherein the first number and the second number are different.

Im Beispiel eines Kochfelds mit geregelter Brat-Funktion kann die Steuereinheit die Zustände in einem Brat-Betriebsmodus, in welchem die Temperatur des Kochgeschirrelements auf einen Wert geregelt wird, der dem eingestellten Betriebsparameter entspricht, auf drei oder vier mögliche Werte des Betriebsparameters abbilden und die Zustände in einem Koch-Betriebsmodus auf 18 mögliche Werte abbilden.In the example of a cooktop with controlled frying function, the control unit can map the conditions in a fry operating mode, in which the temperature of the cookware element is controlled to a value corresponding to the set operating parameter, to three or four possible values of the operating parameter and the states in a cooking mode of operation to 18 possible values.

Ein weiterer Aspekt der Erfindung betrifft ein Verfahren zum Betreiben eines Hausgeräts mit einer Bedienerschnittstelle, die ein Stellelement zum Einstellen eines Betriebsparameters umfasst, wobei in verschiedenen Betriebsmodi eine Zuordnungsfunktion genutzt wird, um jedem Zustand des Stellelements einen Wert des Betriebsparameters zuzuordnen.A further aspect of the invention relates to a method for operating a household appliance with an operator interface, which comprises an actuating element for setting an operating parameter, wherein in different operating modes an assignment function is used to assign a value of the operating parameter to each state of the actuating element.

Zur Weiterbildung eines solchen Verfahrens wird vorgeschlagen, dass die Zuordnungsfunktion abhängig von einem Betriebsmodus bestimmt wird.For further development of such a method, it is proposed that the assignment function is determined as a function of an operating mode.

Weitere Vorteile ergeben sich aus der folgenden Zeichnungsbeschreibung. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Zeichnung, die Beschreibung und die Ansprüche enthalten zahlreiche Merkmale in Kombination. Der Fachmann wird die Merkmale zweckmäßigerweise auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen.Further advantages emerge from the following description of the drawing.

The control unit 10 reads command signals from the operator via the driver unit or user interface 12 and uses an allocation function to process the command signals to associate a value from an allowable value range of the operating parameter to each state of the control element 16.

Erfindungsgemäß wird vorgeschlagen, dass die Steuereinheit 10 insbesondere durch eine geeignete Software dazu ausgelegt ist, die Zuordnungsfunktion abhängig von einem Betriebsmodus zu bestimmen. Die Zuordnungsfunktion kann dazu beispielsweise von einem Parameter abhängen, der seinerseits abhängig von einem gewählten Betriebsmodus ist.According to the invention, it is proposed that the control unit 10 is designed in particular by suitable software to determine the assignment function as a function of an operating mode. The assignment function may depend, for example, on a parameter which in turn depends on a selected operating mode.

Das Kochfeld umfasst zu jeder der fünf Heizzonen 18 zumindest einen Sensor 20 zumThe hob comprises at least one sensor 20 for each of the five heating zones 18

Die Steuereinheit 10 kann das Kochfeld insbesondere in einem Normal-Betriebsmodus betreiben, in welchem der Bediener über die Bedienerschnittstelle 12 eine von 18 möglichen Heizstufen mit ganz- und halbzahligen Werten zwischen 0,5 und 9 wählen kann und einen Brat-Betriebsmodus, in welchem die Steuereinheit 10 die Temperatur des Kochgeschirrelements 22 grob auf einen Sollwert regelt, wobei sie in einem geschlossenen Regelkreis das Signal des unter dem Kochgeschirrelement 22 angeordneten Sensors 20 zum Messen der Temperatur als Rückkopplungsgröße für einen geschlossenen Regelkreis nutzt. In dem Brat-Betriebszustand ist der durch die Zuordnungsfunktion bestimmte Betriebsparameter daher eine Solltemperatur des auf dem Kochfeld angeordneten Kochgeschirrelements 22.The control unit 10 can operate the hob, in particular in a normal operating mode, in which the operator can select one of 18 possible heating stages with integer and half-integer values between 0.5 and 9 via the user interface 12, and a fry operating mode in which the Control unit 10 roughly regulates the temperature of the cookware element 22 to a desired value, using in a closed loop the signal of the temperature measuring sensor 20 located below the cookware element 22 as a closed-loop feedback variable. In the frying operating state, the operating parameter determined by the allocation function is therefore a target temperature of the cooking utensil element 22 arranged on the hob.

Die Bedienerschnittstelle 12 umfasst ein Display 14, das ein Mittel zum Visualisieren der verwendeten Zuordnungsfunktion bildet. Für verschiedene Zuordnungsfunktionen können beliebige verschiedene Symbole verwendet werden. Das Display 14 kann von der Steuereinheit 10 gleichzeitig zum Anzeigen eines eingestellten Werts des Betriebsparameters genutzt werden. Die Zuordnungsfunktion kann auch mittelbar, beispielsweise durch die Darstellung eines Symbols für den verwendeten Betriebsmodus, dargestellt werden. Nach einer kurzen Eingewöhnung wird er Benutzer sich daran gewöhnen können, dass das Stellelement wegen der unterschiedlichen Zuordnungsfunktionen in unterschiedlichen Betriebsmodi unterschiedlich reagiert.The operator interface 12 includes a display 14 that provides a means for visualizing the mapping function used. You can use any number of symbols for different mapping functions. The display 14 can be used by the control unit 10 at the same time for displaying a set value of the operating parameter. The assignment function can also be represented indirectly, for example by the representation of a symbol for the operating mode used. After a short familiarization he will be able to get used to the fact that the actuator reacts differently due to the different assignment functions in different operating modes.

Neben dem Stellelement 16 umfasst die Benutzerschnittstelle 12 noch eine Vielzahl von weiteren Schaltflächen zum Einschalten einer Kindersicherung, zum Konfigurieren einer Timerfunktion, zum Auswählen einer der Heizzonen, zum Ein- und Ausschalten, zum Abrufen von Informationen usw.. Selbstverständlich kann in einem Timer-Einstellmodus auch eine Zeitvorwahl über das Stellelement 16 erfolgen. In anderen Betriebsmodi können weitere Betriebsparameter unter Verwendung des Stellelements 16 verstellt werden.In addition to the actuator 16, the user interface 12 further includes a plurality of other buttons for turning on a child safety lock, configuring a timer function, selecting one of the heating zones, turning on and off, retrieving information, etc. Of course, in a timer setting mode also a time delay via the actuator 16 done. In other modes of operation, further operating parameters may be adjusted using the actuator 16.

Figur 2 zeigt das Stellelement 16 in einer detaillierteren Darstellung. Das Stellelement 16 ist als berührungsempfindlicher Sensorbereich, und zwar als länglicher Sensorstreifen ausgebildet, der parallel zu einer Vorderkante des Kochfelds verläuft. Der Sensorstreifen ist durch hier nicht dargestellte, unter der Abdeckplatte des Kochfelds angeordnete, kapazitive, induktive oder mit Infrarotstrahlung arbeitende Berührungssensoren realisiert. Der Zustand des Stellelements 16 ist insbesondere durch einen Ort einer Berührung des Sensorbereichs durch einen Bediener bestimmt, so dass die Zuordnungsfunktion die Zustände bzw. Berührpunkte mit einer bestimmten Ortsauflösung auf eine endlichen Zahl von möglichen Werten des Betriebsparameters abbildet. Das Stellelement 16 umfasst in dem in Figur 2 dargestellten Ausführungsbeispiel 24 berührungsempfindliche Felder mit jeweils einem Berührungssensor. FIG. 2 shows the actuator 16 in a more detailed representation. The actuator 16 is designed as a touch-sensitive sensor area, namely as an elongated sensor strip, which runs parallel to a front edge of the hob. The sensor strip is realized by not shown here, arranged under the cover plate of the hob, capacitive, inductive or operating with infrared radiation touch sensors. Of the State of the adjusting element 16 is determined in particular by a location of a touch of the sensor area by an operator, so that the assignment function maps the states or contact points with a specific spatial resolution to a finite number of possible values of the operating parameter. The actuator 16 comprises in the in FIG. 2 illustrated embodiment 24 touch-sensitive fields, each with a touch sensor.

Neben dem Ort der Berührung kann eine Dauer der Berührung, eine Intensität der Berührung und/oder eine Geschwindigkeit, mit der der Bediener mit seinem Finger über den Sensorstreifen streicht, zur Charakterisierung des Zustands des Stellelements 16 verwendet werden. Der Zustand des Stellelements 16 kann in diesem Fall durch einen zwei- oder mehrdimensionalen Vektor beschrieben werden, dessen Komponenten den Ort, die Geschwindigkeit und/oder die Dauer der Berührung beschreiben.In addition to the location of the touch, a duration of the touch, an intensity of the touch and / or a speed with which the operator sweeps his finger over the sensor strip can be used to characterize the state of the control element 16. The state of the actuating element 16 in this case can be described by a two- or multi-dimensional vector whose components describe the location, the speed and / or the duration of the contact.

Ferner können die Zuordnungsfunktionen zu den verschiedenen Betriebsmodi vom Benutzer konfigurierbar sein. Der Benutzer kann über einsprechende Schaltelemente der Benutzerschnittstelle beispielsweise eine Anzahl von möglichen Werten der Betriebsparameter, eine Ortsauflösung des Sensorstreifens und/oder eine Empfindlichkeit des Sensorstreifens an seine persönlichen Bedürfnisse anpassen.Furthermore, the mapping functions to the various modes of operation may be user configurable. The user can adjust, for example, a number of possible values of the operating parameters, a spatial resolution of the sensor strip and / or a sensitivity of the sensor strip to his personal needs via influencing switching elements of the user interface.

Die Steuereinheit 10 bestimmt, wie weiter unten detailliert beschrieben, eben diese Ortsauflösung der Zuordnungsfunktion abhängig von dem Betriebsmodus. Die Zuordnungsfunktion ordnet Berührpunkte in wenigstens einem Intervall I1, I2, I3 von Berührpunkten einem Wert des Betriebsparameters zu. Die oben angesprochene Ortsauflösung entspricht der Länge dieser Intervalle I1, I2, I3 (Figur 4).The control unit 10 determines, as described in detail below, just this spatial resolution of the assignment function depending on the operating mode. The assignment function assigns touch points in at least one interval I1, I2, I3 of touch points to a value of the operation parameter. The above-mentioned spatial resolution corresponds to the length of these intervals I1, I2, I3 ( FIG. 4 ).

In einem Ausführungsbeispiel ist entlang des Sensorstreifens eine Reihe von in Figur 2 nur gestrichelt dargestellten Leuchtmitteln 24 angeordnet, von denen in wenigstens einem Betriebsmodus eine Auswahl von Leuchtmitteln 24 aktiviert wird, wobei die Anzahl der aktivierten Leuchtmitteln 24 eine lineare Funktion der Anzahl der möglichen Werte des Betriebsparameters ist und wobei die Positionen der aktivierten Leuchtmittel 24 den Intervallen I1, I2, I3 von Berührpunkten entsprechen, die einem Wert des Betriebsparameters zugeordnet sind. In dem in Figur 2 dargestellten Beispiel ist ein weiter unten detaillierter beschriebener Brat-Betriebsmodus eingestellt, in dem der Betriebsparameter nur drei von Null verschiedene mögliche Werte annehmen kann. Die an den Grenzen von verschiedenen Intervallen I1, I2, I3 angeordneten Leuchtmittel 24 sind in diesem Betriebszustand aktiviert, was durch eine fettere Linie angedeutet ist.In one embodiment, along the sensor strip is a row of in FIG. 2 arranged only in dashed lines bulbs 24, of which in at least one operating mode a selection of bulbs 24 is activated, wherein the number of activated bulbs 24 is a linear function of the number of possible values of the operating parameter and wherein the positions of the activated bulbs 24 the intervals I1 , I2, I3 correspond to points of contact associated with a value of the operating parameter.

FIG. 3 illustrates the mapping function for the normal operating mode. The control unit 10 maps the states in the normal operating state to the 18 possible values of the operating parameter between 0.5 and 9.

Die drei linken Felder des Stellelements 16 werden im Normal-Betriebsmodus dem der Heizleistung Null entsprechenden Betriebsparameter 0 zugeordnet und die vier in Figur 3 rechts angeordneten Felder des Stellelements 16 werden dem der maximalen Leistung bzw. Nominalleistung entsprechenden Wert 9 des Betriebsparameters zugeordnet. Die dazwischen liegenden Felder werden jeweils eineindeutig einem der anderen möglichen Werten 0,5 - 8,5 des Betriebsparameters in der in Figur 3 von links nach rechts aufsteigenden Reihenfolge zugeordnet.The three left fields of the control element 16 are assigned in the normal operating mode corresponding to the heating power zero operating parameters 0 and the four in FIG. 3 right arranged fields of the actuator 16 are assigned to the maximum power or nominal power corresponding value 9 of the operating parameter. The intervening fields are each uniquely one of the other possible values 0.5 - 8.5 of the operating parameter in the in FIG. 3 assigned from left to right ascending order.

Figur 4 illustriert die Zuordnungsfunktion für den Brat-Betriebsmodus. Im Brat-Betriebsmodus kann der Betriebsparameter neben dem Wert 0 nur die Werte "Min", "Med" und "Max" annehmen. Im Brat-Betriebsmodus sind zumindest zwei Intervalle I1, I2, I3, von jeweils einem von null verschiedenen Wert des Betriebsparameters zugeordnet sind, durch ein Zwischenintervall IZ getrennt, wobei die Steuereinheit 10 einen zuvor eingestellten Wert des Betriebsparameters beibehält, wenn eine Berührung in dem Zwischenintervall IZ detektiert wird. FIG. 4 illustrates the mapping function for the fry mode of operation. In Brat operating mode, the operating parameter can only accept the values "Min", "Med" and "Max" in addition to the value 0. In the fry operating mode, at least two intervals I1, I2, I3, each associated with a non-zero value of the operating parameter, are separated by an intermediate interval IZ, wherein the control unit 10 maintains a previously set value of the operating parameter when a touch occurs in the intermediate interval IZ is detected.

Wenn die 24 Felder des Stellelements 16 in der Ansicht von Figur 4 von links nach rechts durchnummeriert werden, sind die Felder mit den Nummern 0 - 4 dem Wert 0 des Betriebsparameters zugeordnet, die Felder mit den Nummern 5-10 sind dem Wert "Min" des Betriebsparameters zugeordnet, das Feld mit der Nummer 11 ist ein Zwischenintervall IZ, die Felder mit den Nummern 12 - 17 sind dem mittleren Wert "Med" des Betriebsparameters zugeordnet, das Feld mit der Nummer 18 ist ein Zwischenintervall IZ und die Felder mit den Nummern 19 - 24 sind dem Wert "Max" des Betriebsparameters zugeordnet.If the 24 fields of the actuator 16 in the view of FIG. 4 are numbered from left to right, the fields with the numbers 0 - 4 are assigned the value 0 of the operating parameter, the fields with the numbers 5-10 are assigned to the value "Min" of the operating parameter, the field with the number 11 is an intermediate interval IZ, the fields numbered 12-17 are assigned to the mean value "Med" of the operating parameter, the field numbered 18 is an intermediate interval IZ and the fields numbered 19-24 are assigned to the value "Max" of the operating parameter.
