Die Erfindung betrifft ein Verfahren zum Betrieb eines Elektrogeräts sowie ein solches Elektrogerät mit einer Bedieneinrichtung.The invention relates to a method for operating an electrical device and to such an electrical device with an operating device.

Aus dem Stand der Technik, beispielsweise der EP 859467 A1 , sind Bedieneinrichtungen für Elektrogeräte bzw. auch entsprechende Elektrogeräte bekannt, für die mehrere Bedienelemente vorgesehen sind. Beispielsweise bei einem Kochfeld als Elektrogerät wird eines der Bedienelemente als Ein-/Aus-Schalter ausgelegt bzw. bildet einen solchen. Dabei können als Bedienelemente eben vorteilhaft sogenannte Berührungsschalter verwendet werden, die auf einem kapazitiven oder induktiven Eingabeprinzip beruhen, unter Umständen auch auf einem optischen, und das Auflegen eines Fingers oder ein leichtes Daraufdrücken mit einer leichten bzw. geringen Auflagekraft erkennen. Hierzu wird auch auf die EP 1704642 A1 verwiesen.From the prior art, for example EP 859467 A1 , Operating devices for electrical devices or corresponding electrical devices are known, for which several control elements are provided. For example, in the case of a hob as an electrical device, one of the control elements is designed as an on / off switch or forms one. So-called touch switches can advantageously be used as operating elements, which are based on a capacitive or inductive input principle, possibly also on an optical one, and recognize the application of a finger or a light pressing on it with a light or low contact force. This also applies to the EP 1704642 A1 directed.

Aus der EP 2258987 A2 ist es bekannt, bei einem Elektrogerät eines der Bedienelemente zum Ausschalten einer Bildschirmanzeige einer Bedieneinrichtung auszulegen.From the EP 2258987 A2 it is known to design one of the control elements for switching off a screen display of an operating device in an electrical device.

Aus der DE 102011010615 A1 ist ein Haushaltsgerät als Elektrogerät bekannt mit einem Bedienelement zum Aktivieren einer Funktion des Haushaltsgeräts durch einen Benutzer. Die Betätigungsdauer des Bedienelements kann erfasst werden, wobei eine Funktion des Haushaltsgeräts nur dann aktiviert oder deren Aktivierung nur dann veranlasst wird, wenn die Betätigungsdauer des Bedienelements unter einem oberen Grenzwert liegt oder diesem entspricht. Dies bedeutet, dass bei einer noch längeren Betätigungsdauer nichts passiert, sondern eben nur dann, wenn das Bedienelement für eine kürzere Dauer betätigt wird.From the DE 102011010615 A1 A household appliance is known as an electrical appliance with an operating element for activating a function of the household appliance by a user. The operating time of the control element can be recorded, a function of the household appliance being activated or activated only when the operating time of the control element is below an upper limit value or corresponds to it. This means that nothing happens during an even longer actuation period, but only if the control element is actuated for a shorter duration.

Aus der DE 10156771 A1 ist ein weiteres Haushaltsgerät bekannt mit einem Hauptschalter, der eine vorbestimmte Einschalt-Betätigungszeitdauer aufweist. Diese ist von einem Benutzer einstellbar. Wird der Hauptschalter für eine darunterliegende Zeitdauer betätigt, so schaltet er nicht ein.From the DE 10156771 A1 Another household appliance is known with a main switch which has a predetermined switch-on actuation period. This can be set by a user. If the main switch is operated for a period below, it does not switch on.

Aus der DE 102004026315 A1 ist es bekannt, an einem Elektroherd ein Betätigungselement und eine mit dem Betätigungselement zusammenwirkende elektrische Schalteinrichtung mit einer Zeitverzögerungsfunktion vorzusehen. Wird das Betätigungselement über eine Mindest-Betätigungsdauer hinaus betätigt, so ist in wenigstens einem Teilbereich des Haushaltsgeräts eine Stromversorgung unterbrochen oder hergestellt.From the DE 102004026315 A1 it is known to provide an actuating element and an electrical switching device cooperating with the actuating element with a time delay function on an electric cooker. If the actuator has a minimum actuation period actuated, a power supply is interrupted or established in at least a portion of the household appliance.

Aufgabe und LösungTask and solution

Der Erfindung liegt die Aufgabe zugrunde, ein eingangs genanntes Verfahren sowie ein zu dessen Durchführung bzw. damit betreibbares Elektrogerät zu schaffen, mit denen Probleme des Stands der Technik vermieden werden können und es insbesondere möglich ist, ein Bedienverfahren bzw. ein Elektrogerät gut bedienen zu können und komfortabel zu machen sowie die Bedieneinrichtung nach Möglichkeit vereinfacht auszubilden.The invention has for its object to provide a method mentioned at the outset and an electrical device for carrying it out or operable therewith, with which problems of the prior art can be avoided and in particular it is possible to be able to operate an operating method or an electrical device well and to make it comfortable and to simplify the control device if possible.

Gelöst wird diese Aufgabe durch ein Verfahren mit den Merkmalen des Anspruchs 1 sowie ein Elektrogerät mit den Merkmalen des Anspruchs 13. Vorteilhafte sowie bevorzugte Ausgestaltungen der Erfindung sind Gegenstand der weiteren Ansprüche und werden im Folgenden näher erläutert. Dabei werden manche der Merkmale nur für das Verfahren oder nur für das Elektrogerät beschrieben. Sie sollen jedoch unabhängig sowohl für das Verfahren als auch für das Elektrogerät selbstständig gelten können. Der Wortlaut der Ansprüche wird durch ausdrückliche Bezugnahme zum Inhalt der Beschreibung gemacht.This object is achieved by a method having the features of claim 1 and an electrical device having the features of claim 13. Advantageous and preferred embodiments of the invention are the subject of the further claims and are explained in more detail below. Some of the features are only described for the method or only for the electrical device. However, they should be able to apply independently both for the method and for the electrical device. The wording of the claims is made the content of the description by express reference.

Es ist vorgesehen, dass zumindest eines der Bedienelemente einer Bedieneinrichtung des Elektrogeräts ein vorgenannter Ein-/Aus-Schalter ist und ein genannter Berührungsschalter ist oder Näherungsschalter oder eben durch Auflegen eines Fingers mit leichter Auflagekraft betätigt werden kann. Mit diesem Ein-/Aus-Schalter kann das Elektrogerät eingeschaltet werden durch entsprechendes Auflegen des Fingers, beispielsweise für eine Zeit von wenigen sek, also aus einem Aus-Zustand heraus. Ausgehend von einem Ein-Zustand des Elektrogeräts kann es wieder ausgeschaltet werden, wenn der Ein-/Aus-Schalter für eine Dauer betätigt wird, die oberhalb eines Schalt-Grenzwerts liegt. Solange muss also ein Finger mindestens auf den Ein-/Aus-Schalter gelegt bzw. dieser betätigt werden. Des Weiteren ist es erfindungsgemäß möglich, ausgehend von diesem Ein-Zustand des Elektrogeräts den Ein-/Aus-Schalter für eine Dauer unterhalb des Schalt-Grenzwerts zu betätigen oder kürzer als diese, wodurch eine Zusatzfunktion oder ein Unter-Menü des Elektrogeräts bedienbar wird bzw. erscheint oder möglich ist. Der Finger wird dazu also vor Ablauf der Dauer des Schalt-Grenzwerts vom Ein-/Aus-Schalter genommen. Diese Zusatzfunktion ist vorteilhaft ein Zusatz-Menü zur Auswahl von weiteren Funktionen am Elektrogerät oder der Eingabe von Einstellungen für einen Betrieb des Elektrogeräts. Dies kann eine Timer-Funktion, ein Ablaufprogramm, eine Energiespar-Funktion, eine Schnellvariante odgl. sein. Bei einem Kochfeld kann es ein Zweikreis-Betrieb einer Kochstelle oder eine Ankoch-Funktion sein.It is provided that at least one of the operating elements of an operating device of the electrical device is a aforementioned on / off switch and is a named touch switch or proximity switch or can be actuated with a slight contact force or simply by placing a finger on it. With this on / off switch, the electrical device can be switched on by correspondingly placing the finger on it, for example for a period of a few seconds, that is, from an off state. Starting from an on-state of the electrical device, it can be switched off again if the on / off switch is actuated for a duration that lies above a switching limit value. As long as a finger must be placed on the on / off switch or this must be operated. Furthermore, it is possible according to the invention to operate the on / off switch for a period below the switching limit value or shorter than this, starting from this on state of the electrical device, whereby an additional function or a submenu of the electrical device can be operated or appears or is possible. For this purpose, the finger is removed from the on / off switch before the duration of the switching limit. This additional function is advantageously an additional menu for selecting further functions on the electrical device or for entering settings for operating the electrical device. This can be a timer function, a sequence program, an energy saving function, a quick variant or the like. his. In the case of a hob, it can be a two-circuit operation of a hotplate or a parboiling function.

Mit einfachen Worten ausgedrückt dient der Ein-/Aus-Schalter dazu, bei längerer Betätigung oberhalb des Schalt-Grenzwerts das Elektrogerät auszuschalten wie üblich. Diese Funktion muss auch aus Sicherheitsgründen und Praxisgründen erhalten bleiben. Wird der Ein-/AusSchalter dagegen kürzer bzw. nur für eine Dauer unterhalb des Schalt-Grenzwerts betätigt und dann auch vor Erreichen des Schalt-Grenzwerts der Finger abgenommen, wird das Elektrogerät nicht ausgeschaltet, sondern die Zusatzfunktion oder das Unter-Menü des Elektrogeräts kann bedient werden. Damit kann ein weiteres Bedienelement, mit dem diese Zusatzfunktion ansonsten aufgerufen werden würde, eingespart werden. Gleichzeitig erfolgt das Ausschalten des Elektrogeräts, insbesondere auch das Einschalten, auf bekannte Art und Weise, wie es auch aus Sicherheitsgründen vorgeschrieben und sinnvoll ist.In simple terms, the on / off switch is used to switch off the electrical device as usual when it is operated for a longer period above the switching limit. This function must also be retained for security and practical reasons. If, on the other hand, the on / off switch is pressed for a short time or only for a period below the switching limit value and then the fingers are removed before the switching limit value is reached, the electrical device is not switched off, but the additional function or the sub-menu of the electrical device can to be served. This saves an additional control element with which this additional function would otherwise be called up. At the same time, the switching off of the electrical device, in particular also the switching on, takes place in a known manner, as is also prescribed and useful for safety reasons.

Für das Ausschalten kann vorgesehen sein, dass sofort nach Überschreiten des Schalt-Grenzwerts das Elektrogerät ausgeschaltet wird, selbst wenn ein Finger weiterhin auf dem Berührungsschalter ruht bzw. der Ein-/Aus-Schalter sozusagen weiterhin betätigt wird. Somit werden die vorgenannten Sicherheitsfunktionen erfüllt.For switching off, it can be provided that the electrical device is switched off immediately after the switching limit value is exceeded, even if a finger is still resting on the touch switch or the on / off switch continues to be operated, so to speak. The aforementioned safety functions are thus fulfilled.

In Ausgestaltung der Erfindung kann vorgesehen sein, dass die Zusatzfunktion oder das Unter-Menü dann mit einem weiteren Bedienelement betätigt oder ausgewählt wird. Hierfür kann eines der günstig erscheinenden anderen Bedienelemente verwendet werden, beispielsweise auch üblicherweise vorgesehene Bedienelemente für eine Leistungseinstellung, die dann bei dieser Einstellfunktion eine andere Wirkung haben.In an embodiment of the invention it can be provided that the additional function or the sub-menu is then actuated or selected with a further control element. For this purpose, one of the other operating elements that appear to be cheap can be used, for example also usually provided operating elements for a power setting, which then have a different effect with this setting function.

Der genannte Schalt-Grenzwert bzw. die Dauer bis zu seinem Erreichen liegt vorteilhaft zwischen 0,5 Sekunden und 5 Sekunden, besonders vorteilhaft zwischen 0,9 Sekunden und 2 Sekunden. So kann sichergestellt werden, dass es subjektiv für eine Bedienperson leicht möglich ist, eine lange Betätigung durchzuführen zum Ausschalten des Elektrogeräts oder eine kurze Betätigung durchzuführen zum Aufrufen der Zusatzfunktion bzw. des Unter-Menüs.The switching limit mentioned or the time until it is reached is advantageously between 0.5 seconds and 5 seconds, particularly advantageously between 0.9 seconds and 2 seconds. In this way it can be ensured that subjectively it is easily possible for an operator to carry out a long operation to switch off the electrical device or a short operation to call up the additional function or the submenu.

Für die Zusatzfunktion kann vorgesehen sein, dass sie oder das Unter-Menü aktivierbar ist bzw. aufgerufen wird, sobald vor Erreichen des Schalt-Grenzwerts die Betätigung des Ein-/Aus-Schalters endet bzw. ein dafür aufgelegter Finger eben abgehoben wird. Hier kann in nochmals weiterer vorteilhafter Ausgestaltung der Erfindung vorgesehen sein, dass zum Aufruf der Zusatzfunktion der Ein-/Aus-Schalter für eine bestimmte Mindestdauer betätigt wird, beispielsweise mindestens 0,1 Sekunden, maximal aber eben bis zu dem genannten Schalt-Grenzwert. So kann vermieden werden, dass bereits eine sehr kurze flüchtige Berührung, die nur beispielsweise bis zu 0,1 Sekunden oder 0,2 Sekunden dauert, die Zusatzfunktion aktiviert bzw. eine Wirkung an der Bedieneinrichtung hervorruft.For the additional function it can be provided that it or the sub-menu can be activated or called up as soon as the activation of the on / off switch ends or a finger placed on it is just lifted off before the switching limit value is reached. In a further advantageous embodiment of the invention, it can be provided here that the on / off switch is actuated for a certain minimum duration to call up the additional function, for example at least 0.1 seconds, but at most up to the switching limit mentioned. In this way it can be avoided that a very brief fleeting touch, which lasts, for example, only up to 0.1 seconds or 0.2 seconds, activates the additional function or has an effect on the operating device.

In nochmals weiterer Ausgestaltung der Erfindung kann vorgesehen sein, dass optische und/oder akustische Signale an eine Bedienperson ausgegeben werden. Dies kann erfolgen, wenn das Elektrogerät ausgeschaltet wird bzw. in den Aus-Zustand versetzt wird. Des Weiteren kann es erfolgen, wenn die Zusatzfunktion oder das Unter-Menü bedienbar oder aktivierbar ist.In yet another embodiment of the invention, it can be provided that optical and / or acoustic signals are output to an operator. This can be done when the electrical device is switched off or is switched to the off state. Furthermore, it can be done if the additional function or the sub-menu can be operated or activated.

Vorteilhaft erfolgt in beiden Fällen ein Signal mit Änderung des Zustands des Elektrogeräts bzw. Aktivierbarkeit oder Bedienbarkeit der Zusatzfunktion. Die Signale können sich jeweils unterscheiden, beispielsweise ein Ton bzw. Piepston oder ein Blinken für das Ausschalten des Elektrogeräts und ein doppelter Piepston oder ein doppeltes Blinken für die bedienbare Zusatzfunktion.In both cases, a signal with a change in the state of the electrical appliance or activation or operability of the additional function advantageously takes place. The signals can differ, for example a tone or beep or a blink for switching off the electrical device and a double beep or a double blink for the additional function that can be operated.

In weiterer Ausgestaltung der Erfindung kann vorgesehen sein, dass nach dem Aktivieren der Zusatzfunktion und des Unter-Menüs eine bestimmte Maximaldauer vorgesehen ist für diesen Zustand bzw. für deren weitere Spezifikation oder Ausführung. So kann die Ausführbarkeit der Zusatzfunktion und Aktivierbarkeit des Unter-Menüs nach maximal 30 oder 20 sek wieder zurückgenommen werden, vorteilhaft nach maximal 10 Sekunden.In a further embodiment of the invention, it can be provided that after activating the additional function and the submenu, a certain maximum duration is provided for this state or for its further specification or execution. So the feasibility of Additional functions and activability of the sub-menu can be withdrawn after a maximum of 30 or 20 seconds, advantageously after a maximum of 10 seconds.

In vorteilhafter Ausgestaltung der Erfindung kann insbesondere zur Einhaltung der Sicherheitsvorschriften vorgesehen sein, dass ein Betätigen des Ein-/Aus-Schalters direkt mit Berühren mit einem Finger aus dem Ein-Zustand des Elektrogeräts heraus die Zusatzfunktion und das Unter-Menü oder deren Aktivierbarkeit wieder zurücknimmt. Dabei kann einerseits vorgesehen sein, dass ein kurzes Betätigen des Ein-/Aus-Schalters, insbesondere mit einer Dauer unterhalb des Schalt-Grenzwerts und anschließendem Abnehmen des Fingers, diese Zurücknahme bewirkt. Andererseits kann vorgesehen sein, dass das Betätigen des Ein-/Aus-Schalters für eine Dauer oberhalb des Schalt-Grenzwerts auch bei aktivierter Bedienbarkeit der Zusatzfunktion das Elektrogerät auf vorgenannte Art und Weise ausschaltet, unter Umständen mit zuerst erfolgendem und sofortigem Deaktivieren der Zusatzfunktion bzw. des Unter-Menüs. Es muss also nicht zuerst die Aktivierbarkeit der Zusatzfunktion beendet werden, um danach das Elektrogerät ausschalten zu können, sondern dies kann direkt in einem Schritt erfolgen.In an advantageous embodiment of the invention, in particular to comply with the safety regulations, it can be provided that actuating the on / off switch directly by touching with a finger withdraws the additional function and the submenu or its activability from the on state of the electrical device , On the one hand, it can be provided that a brief actuation of the on / off switch, in particular with a duration below the switching limit value and subsequent removal of the finger, brings about this withdrawal. On the other hand, it can be provided that the actuation of the on / off switch for a period above the switching limit value switches off the electrical device in the aforementioned manner even if the additional function can be operated, possibly with the additional function being activated first and immediately or of the sub-menu. The activation of the additional function does not have to be ended first so that the electrical device can then be switched off, but this can be done directly in one step.

Das Elektrogerät, welches einerseits ein Elektrokochgerät bzw. Elektrohaushaltsgerät sein kann wie insbesondere neben einem vorgenannten Kochfeld oder Backofen auch eine Wasch- oder Spülmaschine oder ein sonstiges Elektrogerät, weist eben eine vorgenannte Bedieneinrichtung mit entsprechend ausgebildeten Bedienelementen auf. Bei den Bedienelementen ist zumindest der Ein-/Aus-Schalter als sogenannter Berührungsschalter oder Näherungsschalter ausgebildet. Vorteilhaft gilt dies aber auch für die anderen Bedienelemente bzw. alle Bedienelemente arbeiten nach dem gleichen Funktionsprinzip. Die Bedieneinrichtung kann an dem Elektrogerät in günstiger Art und Weise angebracht sein, beispielsweise entsprechend der vorgenannten EP 2258987 A2 . Als vorgenannte Anzeige kann eine wie dort auch dargestellte großflächige optische Anzeige verwendet werden, alternativ können auch aus der vorgenannten EP 859467 A1 bekannte kleine Leuchtanzeigen vorgesehen sein. Als akustische Anzeige kann ein üblicherweise verwendeter Pieper bzw. Buzzer oder Piezo-Summer verwendet werden.The electrical appliance, which on the one hand can be an electric cooking appliance or electrical household appliance, such as, in particular, a washing machine or dishwasher or another electrical appliance, in addition to the aforementioned hob or oven, has a control device with appropriately designed control elements. In the operating elements, at least the on / off switch is designed as a so-called touch switch or proximity switch. However, this advantageously also applies to the other operating elements or all operating elements work according to the same functional principle. The operating device can be attached to the electrical device in a favorable manner, for example in accordance with the aforementioned EP 2258987 A2 , A large-area optical display, as also shown there, can be used as the aforementioned display, alternatively also from the aforementioned EP 859467 A1 known small indicator lights can be provided. A beeper or buzzer or piezo buzzer that is commonly used can be used as the acoustic display.

Detaillierte Beschreibung der AusführungsbeispieleDetailed description of the exemplary embodiments

In der Fig. 1 ist in Draufsicht ein Kochfeld 11 dargestellt als Beispiel für ein Elektrogerät neben den vorgenannten, wobei ähnliche Elektrohaushaltsgeräte eben auch Spül-/Waschmaschinen, Öfen, Mikrowellen odgl. sein können. Das Kochfeld 11 weist eine Kochfeldplatte 12 und daran vier Kochstellen 13a bis 13d auf. Um deren Bedienung geht es bei der Erfindung hauptsächlich.In the Fig. 1 is a top view of a hob 11 is shown as an example of an electrical appliance in addition to the above, similar electrical household appliances just dishwashers / washers, ovens, microwaves or the like could be. The cooktop 11 has a cooktop plate 12 and four cooktops 13a to 13d thereon. The invention is mainly concerned with their operation.

Im vorderen Bereich weist das Kochfeld 11 ein Display 15 auf und im linken vorderen Eckbereich einen Ein-/Aus-Schalter 17. Links und rechts neben dem Display 15 sind weitere Bedienelemente 19 vorgesehen. Eine Steuerung 21 für das Kochfeld 11 ist gestrichelt dargestellt. Sie ist mit den Bedienelementen 17 und 19 sowie dem Display 15 verbunden und zusätzlich weist sie einen Pieper 22 auf. Zusätzlich können die Bedienelemente 17 bzw. 19 beleuchtet sein, was beispielsweise für den Ein-/Aus-Schalter 17 durch die schematisch dargestellten Lichtstrahlen 18 angedeutet wird.The hob 11 has a display 15 in the front area and an on / off switch 17 in the left front corner area. Further operating elements 19 are provided to the left and right of the display 15. A control 21 for the hob 11 is shown in dashed lines. It is connected to the control elements 17 and 19 and the display 15 and additionally has a beeper 22. In addition, the operating elements 17 and 19 can be illuminated, which is indicated, for example, for the on / off switch 17 by the schematically illustrated light beams 18.

Der Ein-/Aus-Schalter 17 ist als eingangs genannter Berührschalter ausgebildet, vorteilhaft als kapazitiver Berührungsschalter. Er kann beleuchtet sein bzw. Leuchtmittel aufweisen für die Lichtstrahlen 18. Für die Bedienelemente 19 kann dasselbe gelten, alternativ können sie auch ein anderes Funktionsprinzip aufweisen. Des Weiteren können die Bedienelemente 19, unter Umständen sogar der Ein-/Aus-Schalter 17, in eine Anzeige entsprechend dem Display 15 integriert sein als sogenannter Touch-Screen. Dies ändert aber auch nichts an ihrer jeweiligen Funktionalität.The on / off switch 17 is designed as a touch switch mentioned at the outset, advantageously as a capacitive touch switch. It can be illuminated or have illuminants for the light beams 18. The same can apply to the operating elements 19, alternatively they can also have a different functional principle. Furthermore, the control elements 19, possibly even the on / off switch 17, can be integrated in a display corresponding to the display 15 as a so-called touch screen. However, this does not change their respective functionality.

In der Fig. 2 ist dargestellt, was im zeitlichen Verlauf mit einer Betätigung des Ein-/Aus-Schalters 17 bewirkt werden kann. Der oberste Verlauf entspricht eben diesem Ein-/Aus-Schalter 17, der Verlauf darunter dem ganzen Kochfeld 11 bzw. zeigt dessen Aktivierungszustand an. Der Verlauf darunter wiederum stellt den Betriebszustand des Piepers 22 dar. Der unterste Verlauf stellt die Bedienbarkeit bzw. Aktivierbarkeit der Zusatzfunktion bzw. des Unter-Menüs dar.In the Fig. 2 is shown what can be effected over time with an actuation of the on / off switch 17. The top course corresponds to this on / off switch 17, the course below it to the entire hob 11 or indicates its activation state. The course below it in turn represents the operating state of the beeper 22. The lowest course represents the operability or activability of the additional function or the submenu.

Bei allen vier Verläufen stellt der obere Wert "1" die Betätigung bzw. Aktivierung dar und der untere Zustand "0" den nicht-betätigten bzw. ausgeschalteten oder deaktivierten Zustand.In all four courses, the upper value "1" represents the actuation or activation and the lower state "0" the non-actuated or switched off or deactivated state.

Falls das Kochfeld 11 noch nicht eingeschaltet ist, wird es mit dem Ein-/Aus-Schalter 17 eingeschaltet, insbesondere durch Betätigen durch Auflegen eines Fingers für eine bestimmte Zeit bzw. vorteilhaft für eine Zeit, die über dem Schalt-Grenzwert TS liegt, der hier als 2 Sekunden definiert ist. Vom eingeschalteten Zustand des Kochfelds 11 ausgehend wird zum Zeitpunkt t1 ein Finger auf den Ein-/Aus-Schalter gelegt bzw. dessen Betätigung sozusagen begonnen. Im hier dargestellten Zustand wird der Finger zum Zeitpunkt t2 wieder abgenommen, so dass der Ein-/Ausschalter 17 nicht mehr betätigt ist. Dies erfolgt für eine Zeitdauer T1, die erkennbar kleiner ist als der Schalt-Grenzwert TS. Deswegen ist nun ein hier nicht weiter ausgeführtes Unter-Menü bzw. eine Zusatzfunktion aktivierbar bzw. bedienbar, wie sie zuvor genannt worden sind, weswegen der unterste Verlauf auf den Zustand "1" springt. Diese Änderung des Zustands für die Zusatzfunktion bzw. das Unter-Menü wird sofort durch den Pieper 22 mit einem erkennbaren Doppelsignal angezeigt. Alternativ oder zusätzlich kann diese Zustandsänderung auch mittels der Lichtstrahlen 18 am Ein-/Aus-Schalter 17 angezeigt werden.If the cooktop 11 is not yet switched on, it is switched on using the on / off switch 17, in particular by actuating by placing a finger on it for a certain time or advantageously for a time which is above the switching limit value T S , which is defined here as 2 seconds. Starting from the switched-on state of the hob 11, a finger is placed on the on / off switch at the time t 1 or its actuation, so to speak, begins. In the state shown here, the finger is removed again at time t 2 , so that the on / off switch 17 is no longer actuated. This takes place for a time period T 1 that is recognizably smaller than the switching limit value T S. For this reason, a submenu or an additional function, as not mentioned here, can now be activated or operated, as previously mentioned, which is why the bottom course jumps to state "1". This change in the status for the additional function or the sub-menu is immediately indicated by the beeper 22 with a recognizable double signal. Alternatively or additionally, this change in state can also be indicated by means of the light beams 18 on the on / off switch 17.

Ab dem Zeitpunkt t2 ist die Zusatzfunktion bzw. das Unter-Menü bedienbar bzw. aktivierbar. Ob dies nun tatsächlich erfolgt oder nicht, spielt keine Rolle. Im gepunktet dargestellten unteren Verlauf ist eine hierfür vorgesehene Zeitdauer überschritten worden, so dass der Zustand wieder auf "0" zurückgeht und die Bedienbarkeit bzw. Aktivierbarkeit der Zusatzfunktion bzw. des Unter-Menüs wieder wegfällt bzw. entfällt.From time t 2 , the additional function or the sub-menu can be operated or activated. It does not matter whether this is actually done or not. In the lower curve shown in dotted lines, a time period provided for this has been exceeded, so that the state returns to "0" and the operability or activatability of the additional function or of the submenu is no longer applicable.

Alternativ kann diese vorgesehene Zeitdauer noch nicht erreicht werden, was dem strichpunktiert dargestellten oberen Verlauf entspricht. Da nun zum Zeitpunkt t3 der Ein-/Aus-Schalter 17 durch Auflegen eines Fingers erneut betätigt wird, was durch seine Zustandsänderung auf "1" angezeigt wird, wird die Aktivierbarkeit bzw. Bedienbarkeit der Zusatzfunktion bzw. des Unter-Menüs sofort wieder rückgängig gemacht und der Zustand auf "0" gesetzt.Alternatively, this intended period of time cannot yet be reached, which corresponds to the upper course shown in dash-dot lines. Since, at time t 3, the on / off switch 17 is actuated again by placing a finger on it, which is indicated by its change in state to "1", the activatability or operability of the additional function or of the submenu is immediately reversed made and the state set to "0".

Diese zweite Betätigung des Ein-/Aus-Schalters 17 dauert länger als der Schalt-Grenzwert TS, also länger als 2 Sekunden. Deswegen wird zum Zeitpunkt t4 das Kochfeld 11 ausgeschaltet und sein Zustand auf "0" gesetzt. Dies wiederum wird direkt durch ein längeres Signal des Piepers 22 angezeigt, unter Umständen auch wieder durch Lichtstrahlen 18. Hier ist dargestellt, dass der Finger bis zum Zeitpunkt t5 auf dem Ein-/Aus-Schalter 17 ruht und erst später, beispielsweise nach 3 Sekunden oder mehr, abgehoben wird. Dies ändert aber erkennbar nichts an einem der Zustände. This second actuation of the on / off switch 17 lasts longer than the switching limit value T S , that is to say longer than 2 seconds. Therefore, the hob 11 is switched off at time t 4 and its state is set to "0". This in turn is indicated directly by a longer signal from the beeper 22, under certain circumstances also by light rays 18. It is shown here that the finger rests on the on / off switch 17 until the time t 5 and only later, for example after FIG. 3 Seconds or more. But this obviously does not change anything in one of the states.
