Description

Die Erfindung betrifft eine Bedienvorrichtung fĆ¼r ein HausgerƤt mit einem Bedienelement. Des Weiteren betrifft die Erfindung ein HausgerƤt zum Zubereiten von Lebensmitteln, insbesondere ein Kochfeld, mit einer derartigen Bedienvorrichtung.The invention relates to an operating device for a domestic appliance with a control element. Furthermore, the invention relates to a domestic appliance for preparing food, in particular a hob, with such an operating device.

Bedienvorrichtungen, die einen auf eine Kochfeldplatte positionierbaren Bedienknebel aufweisen, sind bekannt. Dieser Bedienknebel wird mit MagnetkrƤften gehalten und kann zur Betriebseinstellung um seine Achse gedreht werden.Operating devices which have a positionable on a cooktop control knob are known. This control knob is held with magnetic forces and can be rotated around its axis for operation adjustment.

Bei derartigen Bedienvorrichtungen sind oftmals eine Vielzahl von Betriebsbedingungen einstellbar, so dass auch eine Vielzahl von unterschiedlichen Informationen auf eine Anzeigeeinheit der Bedienvorrichtung angezeigt wird. Dies und aufgrund der Tatsache, dass beispielsweise bei einem Kochfeld die Kochzonen einen groƟen Platzbedarf in Anspruch nehmen, ist die Anzeigeeinheit der Bedienvorrichtung oftmals relativ klein dimensioniert. Daraus folgt, dass auch die anzuzeigenden Informationen relativ klein und unĆ¼bersichtlich dargestellt sind.In such operating devices, a plurality of operating conditions are often adjustable, so that a plurality of different information is displayed on a display unit of the operating device. This and due to the fact that, for example, in a cooktop, the cooking zones take up a large amount of space, the display unit of the operating device is often relatively small dimensions. It follows that also the information to be displayed is shown relatively small and confusing.

Es ist Aufgabe der vorliegenden Erfindung, eine Bedienvorrichtung fĆ¼r ein HausgerƤt zu schaffen, sowie ein HausgerƤt mit einer entsprechenden Bedienvorrichtung zu schaffen, mit welcher bzw. mit welchem die optische Anzeige verbessert und leichter nachvollziehbar ermƶglicht ist.It is an object of the present invention to provide an operating device for a domestic appliance, and to provide a domestic appliance with a corresponding operating device, with which or with which the visual display is improved and made easier to understand.

Diese Aufgabe wird durch eine Bedienvorrichtung, welche die Merkmale nach Anspruch 1 aufweist, und ein HausgerƤt, welches die Merkmale nach Anspruch 11 aufweist, gelƶst.This object is achieved by an operating device having the features of claim 1, and a domestic appliance having the features of claim 11.

Eine erfindungsgemƤƟe Bedienvorrichtung fĆ¼r ein HausgerƤt umfasst ein Bedienelement. An einer Oberseite des Bedienelements ist ein Anzeigebereich ausgebildet, welcher ein optisches VergrĆ¶ĆŸerungselement aufweist, mit welchem dargestellte Informationen gegenĆ¼ber ihrer ursprĆ¼nglichen GrĆ¶ĆŸe vergrĆ¶ĆŸert sind. FĆ¼r eine derartige Ausgestaltung wird somit durch ein ganz speziell ausgebildetes Bauteil, nƤmlich das Bedienelement, zum einen die Informationsanzeige in das Bedienelement integriert und darĆ¼ber hinaus wird auch eine leichtere und schnell nachvollziehbare InformationsprƤsentation durch die VergrĆ¶ĆŸerung gewƤhrleistet. Zum einen kƶnnen somit entsprechende anzuzeigende Informationen, wie beispielsweise Zahlen als Werte von eingestellten Betriebsparametern oder auch Buchstaben und Texte fĆ¼r einen Nutzer schneller und fehlerfrei erkannt werden.An operating device according to the invention for a domestic appliance comprises an operating element. On an upper side of the operating element, a display area is formed, which has an optical magnification element, with which displayed information is increased in relation to its original size. For such a design is thus integrated by a very specially trained component, namely the control element, on the one hand, the information display in the control and, moreover, an easier and quickly comprehensible information presentation is ensured by the magnification. On the one hand, therefore, corresponding information to be displayed, such as, for example, numbers as values of set operating parameters or also letters and texts for a user, can be recognized faster and without error.

Es kƶnnen in diesem Zusammenhang entweder nur einige ganz spezifische und abhƤngig von spezifischen Betriebssituationen vorliegende Informationen in dem Bedienelement und darĆ¼ber hinaus vergrĆ¶ĆŸert anzeigbar sein.In this context, either only a very specific information that is available depending on specific operating situations can be displayed in the operating element and, in addition, enlarged.

Es kann grundsƤtzlich auch vorgesehen sein, dass die gesamte Informationsdarstellung von Betriebsparameterwerten auf dem Anzeigebereich des Bedienelements bzw. Ć¼ber das Bedienelement erfolgt und durch das VergrĆ¶ĆŸerungselement diese Information dann auch vergrĆ¶ĆŸert dargestellt wird.In principle, it can also be provided that the entire information representation of operating parameter values takes place on the display area of the operating element or via the operating element, and this information is then enlarged by the enlarging element.

Durch die Integration in das Bedienelement und die VergrĆ¶ĆŸerung wird quasi in hervorspringender Weise und im Vergleich zum Niveau der BedienflƤche an erhƶhter Stelle fĆ¼r den Nutzer eine InformationsprƤsentation ermƶglicht. Insbesondere die VergrĆ¶ĆŸerung ermƶglicht auch fĆ¼r im Sehvermƶgen eingeschrƤnkte Nutzer leichtere und zuverlƤssigere Erkennbarkeit. Nicht zuletzt wird somit durch das VergrĆ¶ĆŸerungselement und die damit erzielte VergrĆ¶ĆŸerung in der Informationsdarstellung auch einem besseren Sicherheitsaspekt Rechnung getragen.Due to the integration into the control element and the enlargement, an information presentation is made possible in a prominent manner and in comparison with the level of the control surface at an elevated point for the user. In particular, the magnification also enables easier for the eyesight users and more reliable visibility. Last but not least, a better safety aspect is thus taken into account by the enlarging element and the enlargement thus achieved in the information representation.

Insbesondere ist das Bedienelement auf einer BedienflƤche des mit der Bedienvorrichtung steuerbaren HausgerƤts mittels Magnetkraft haltbar ist und relativ zur BedienflƤche bewegbar und von dort abnehmbar positionierbar.In particular, the operating element on a control surface of the controllable with the operating device domestic appliance by means of magnetic force is durable and movable relative to the control surface and removably positionable from there.

Vorzugsweise ist das VergrĆ¶ĆŸerungselement eine Lupe. Damit wird quasi ein einziges einstĆ¼ckiges Element geschaffen, welches diese VergrĆ¶ĆŸerung gewƤhrleistet. Zum einen kann durch diese Ausgestaltung eine einfache und relativ kostengĆ¼nstige Herstellung ermƶglicht werden. DarĆ¼ber hinaus ist dieses Element relativ robust und verschleiƟarm. Vorzugsweise ist vorgesehen, dass dann, wenn das VergrĆ¶ĆŸerungselement quasi das oberste Bauteil des Bedienelements darstellt und somit quasi nach oben hin frei zugƤnglich ist, zusƤtzlich eine entsprechende Beschichtung oder Folie aufgebracht ist, welche als VerschleiƟschutz, beispielsweise vor Verkratzen oder dergleichen, das VergrĆ¶ĆŸerungselement schĆ¼tzt.Preferably, the magnifying element is a magnifying glass. This virtually creates a single integral element which ensures this enlargement. On the one hand, a simple and relatively inexpensive production can be made possible by this configuration. In addition, this element is relatively robust and low-wear. It is preferably provided that when the magnification element is quasi the uppermost component of the control element and thus is virtually freely accessible, in addition a corresponding coating or foil is applied which protects the magnification element as wear protection, for example against scratching or the like.

Bei einer vorteilhaften Ausgestaltung kann vorgesehen sein, dass das Bedienelement selbst eine Informationserzeugungseinheit aufweist. Das VergrĆ¶ĆŸerungselement ist dann insbesondere Ć¼ber der Informationserzeugungseinheit zur VergrĆ¶ĆŸerung der in dem Bedienelement selbst erzeugten Informationen angeordnet. Beispielsweise kann vorgesehen sein, dass das Bedienelement eine integrierte elektrische Anzeigeeinheit aufweist, welche beispielsweise zur Anzeige von Symbolen und/oder Buchstaben und/oder Zahlen ausgebildet ist. Dazu kƶnnen auf einem SchaltungstrƤger des Bedienelements entsprechende Bauteile ausgebildet sein. So kƶnnen hier auch beispielsweise so genannten Sieben-Segment-Anzeigen vorgesehen sein. Wird nun eine entsprechende Information erzeugt und Ć¼ber die Anzeigeeinheit des Bedienelements angezeigt, so wird mittels des VergrĆ¶ĆŸerungselements diese bedienelementinterne Information nach oben hin vergrĆ¶ĆŸert dargestellt. So wird somit bei Draufsicht und Betrachtung des Bedienelements die VergrĆ¶ĆŸerungswirkung generiert und die anzuzeigende Information vergrĆ¶ĆŸert dargestellt.In an advantageous embodiment it can be provided that the operating element itself has an information-generating unit. The enlarging element is then arranged in particular over the information-generating unit for enlarging the information generated in the operating element itself. For example, it can be provided that the operating element has an integrated electrical display unit which is designed, for example, to display symbols and / or letters and / or numbers. For this purpose, corresponding components can be formed on a circuit carrier of the operating element. Thus, for example, so-called seven-segment displays can also be provided here. If a corresponding information is now generated and displayed via the display unit of the control element, then this operating element-internal information is displayed enlarged upward by means of the magnification element. Thus, the magnification effect is thus generated in plan view and viewing of the control element and the information to be displayed displayed enlarged.

Besonders vorteilhaft ist es, wenn das Bedienelement einen fĆ¼r Licht im fĆ¼r den Menschen sichtbaren Spektralbereich durchlƤssigen Bereich aufweist und Ć¼ber und/oder unter diesem Bereich ein VergrĆ¶ĆŸerungselement angeordnet ist, mit welchem auf einer Anzeigeeinheit der BedienflƤche angezeigte Informationen durch das Bedienelement hindurch vergrĆ¶ĆŸert anzeigbar sind. Dies ist eine besonders hervorzuhebende AusfĆ¼hrung, da somit das Bedienelement quasi als zumindest bereichsweise durchsichtiges Bauteil ausgebildet ist. Wird es somit auf die BedienflƤche aufgesetzt und zwar im Bereich einer Anzeigeeinheit der BedienflƤche selbst, so kƶnnen die auf der Anzeigeeinheit dargestellten Informationen in Form von Symbolen und/oder Buchstaben und/oder Zahlen durch das Bedienelement hindurch vergrĆ¶ĆŸert dargestellt werden. Auch hier kann somit dann quasi das Bedienelement auf die Anzeigeeinheit aufgesetzt werden und der Nutzer kann bei Betrachtung des Bedienelements von oben die auf der Anzeigeeinheit der BedienflƤche dargestellten Informationen vergrĆ¶ĆŸert wahrnehmen. Vorzugsweise weist das Bedienelement eine Vertiefung auf, in welcher das VergrĆ¶ĆŸerungselement angeordnet ist. Dadurch kann das VergrĆ¶ĆŸerungselement sicher und stabil gehalten werden. Eine derartige Einbettung ermƶglicht auch zumindest zur Seite hin StoƟschutz und einen VerschleiƟschutz. UnerwĆ¼nschtes Verkratzen oder Verschmieren mit Fett oder dergleichen kann dadurch vermieden werden. Die jederzeit zuverlƤssige Betrachtung der vergrĆ¶ĆŸerten Informationen ist dadurch gewƤhrleistet.It is particularly advantageous if the operating element has a region permeable to light in the spectral range visible to humans and a magnification element is arranged above and / or below this region, with which information displayed on a display unit of the operating surface can be displayed enlarged by the operating element. This is a particularly noteworthy embodiment, since thus the operating element is formed quasi as at least partially transparent component. If it is thus placed on the operating surface and indeed in the area of a display unit of the operating surface itself, the information displayed on the display unit in the form of symbols and / or letters and / or numbers can be represented enlarged by the operating element. Here, too, the operating element can be placed on the display unit, as it were, and the user can perceive the information displayed on the display unit of the operating surface enlarged when the operating element is viewed from above. Preferably, the operating element has a depression in which the enlarging element is arranged. Thereby, the enlarging element can be securely and stably held. Such embedding also allows impact protection and wear protection at least to the side. Unwanted scratching or smearing with grease or the like can be avoided. The always reliable view of the enlarged information is guaranteed.

Vorzugsweise ist das VergrĆ¶ĆŸerungselement in das Bedienelement integriert. Durch eine derartige integrale und insbesondere zerstƶrungsfrei nicht lƶsbare Ausgestaltung kƶnnen unerwĆ¼nschte Positionstoleranzen vermieden werden.Preferably, the magnifying element is integrated in the operating element. By such an integral and in particular non-destructive non-detachable design unwanted position tolerances can be avoided.

Es kann auch vorgesehen sein, dass das VergrĆ¶ĆŸerungselement reversibel zerstƶrungsfrei lƶsbar an dem Bedienelement, insbesondere in der oberen Abdeckung, angeordnet ist. Dazu kann vorgesehen sein, dass kompatibel unterschiedliche VergrĆ¶ĆŸerungselemente mit unterschiedlicher VergrĆ¶ĆŸerungswirkung in das Bedienelement eingebaut werden kƶnnen. Durch die KompatibilitƤt kann dies auch nutzerseitig einfach und schnell durchgefĆ¼hrt werden. Beispielsweise kann hier eine Anbringung mit einem bodenseitigen doppelseitigen Klebeband oder einer Steckverbindung oder einer Rastverbindung oder dergleichen vorgesehen sein.It can also be provided that the magnifying element is reversibly arranged non-destructively releasably on the operating element, in particular in the upper cover. For this purpose, it can be provided that compatible different magnification elements with different magnification effect can be installed in the control. Due to the compatibility, this can also be done easily and quickly by the user. For example, an attachment may be provided here with a bottom-side double-sided adhesive tape or a plug connection or a latching connection or the like.

Vorzugsweise ist vorgesehen, dass sich das VergrĆ¶ĆŸerungselement im Wesentlichen Ć¼ber die gesamte OberflƤche des Bedienelements erstreckt und somit eine maximale FlƤchenausnutzung fĆ¼r die VergrĆ¶ĆŸerungswirkung gegeben ist. Insbesondere ist lediglich ein um das VergrĆ¶ĆŸerungselement umlaufender dĆ¼nner Randsteg vorgesehen, der dann auch zugleich die Halterung in der Vertiefung gewƤhrleistet.It is preferably provided that the enlarging element extends substantially over the entire surface of the operating element and thus a maximum area utilization is given for the enlargement effect. In particular, only one surrounding the enlarging element thin edge web is provided, which then also ensures the holder in the recess.

Vorzugsweise ist das Bedienelement als Dreh-Bedienknebel ausgebildet. Bei einer derartigen Ausgestaltung ist lediglich vorgesehen, dass Betriebsbedingungseinstellungen nur durch ein Drehen um eine Vertikalachse bzw. LƤngsachse des Bedienelements ermƶglicht ist. Besonders vorteilhaft ist es, wenn das Bedienelement ein Dreh-Kipp-Bedienknebel ist. Bei einer derartigen Ausgestaltung kann somit durch Drehen als auch durch Kippen um bzw. relativ zur LƤngsachse des Bedienelements eine Betriebsbedienungseinstellung erfolgen. So kann beispielsweise vorgesehen sein, dass aufgrund der unebenen Unterseite des Bedienelements eine Kippbewegung mƶglich ist, mit der beispielsweise eine Kochzone eines Kochfels auswƤhlbar ist. Wird dann im gekippten oder dann aus dem gekippten in den ungekippten Zustand zurĆ¼ckbewegten Bedienelement ein Drehen um die LƤngsachse des Bedienelements durchgefĆ¼hrt, kann dann ein Betriebsparameter der ausgewƤhlten Kochzone wertmƤƟig eingestellt werden.Preferably, the control element is designed as a rotary control knob. In such an embodiment, it is merely provided that operating condition settings are made possible only by turning about a vertical axis or longitudinal axis of the operating element. It is particularly advantageous if the operating element is a turn-tilt control knob. In such a configuration can thus be done by turning and by tilting about or relative to the longitudinal axis of the operating element operating control setting. For example, it may be provided that due to the uneven underside of the control element, a tilting movement is possible with which, for example, a cooking zone of a cooking rock is selectable. If a rotation about the longitudinal axis of the operating element is then carried out in the tilted or then returned from the tilted in the non-tilted state control, then an operating parameter of the selected cooking zone can be set in terms of value.

Vorzugsweise weist das Bedienelement einen ƤuƟeren Ring auf, welcher als Halterung des VergrĆ¶ĆŸerungselements ausgebildet ist und zur magnetischen Wechselwirkung mit Sensoren separat zum Bedienelement zur Betriebseinstellung abhƤngig von einer Bewegung des Bedienelements relativ zur BedienflƤche ausgebildet ist. Es sind bei einer derartigen Ausgestaltung somit Sensoren bedienelementextern angeordnet, beispielsweise unter der BedienflƤche, die aufgrund von PositionsƤnderungen des Bedienelements relativ zur BedienflƤche in Form von magnetischen Wechselwirkungen die PositionsƤnderung detektieren und die damit verbundenen Betriebsbedingungseinstellungen erkennen.Preferably, the control element has an outer ring, which is designed as a holder of the enlargement element and is designed for magnetic interaction with sensors separately from the operating element for operating adjustment depending on a movement of the operating element relative to the operating surface. Thus, in such an embodiment, sensors are arranged outside the control element, for example under the control surface, which detect the change in position relative to the control surface in the form of magnetic interactions due to changes in position of the control element and recognize the associated operating condition settings.

Der Ring kann definierte Teilsegmente aufweisen, die als Magnete ausgebildet sind. Diese kƶnnen in dem Ring integriert sein. Es kƶnnen auch spezifische Teilbereiche des Rings magnetisiert sein.The ring may have defined sub-segments, which are formed as magnets. These can be integrated in the ring. Specific portions of the ring may also be magnetized.

Des Weiteren betrifft die Erfindung ein HausgerƤt zur Zubereitung von Lebensmitteln, insbesondere ein Kochfeld, mit einer erfindungsgemƤƟen Bedienvorrichtung oder einer vorteilhaften Ausgestaltung davon.Furthermore, the invention relates to a domestic appliance for the preparation of food, in particular a hob, with an operating device according to the invention or an advantageous embodiment thereof.

Weitere vorteilhafte AusfĆ¼hrungen ergeben sich aus den AnsprĆ¼chen, den Figuren und der Figurenbeschreibung.

An embodiment of an inventive control element of an operating device according to the invention in a perspective view.

In den Figuren werden gleiche oder funktionsgleiche Elemente mit den gleichen Bezugszeichen versehen.In the figures, identical or functionally identical elements are provided with the same reference numerals.

In Fig. 1 ist eine Draufsicht auf ein Kochfeld 1 gezeigt, welches eine Kochfeldplatte 2 aufweist. Auf einer Oberseite bzw. BedienflƤche 3 der Kochfeldplatte 2, welche beispielsweise aus Glaskeramik oder Glas ausgebildet sein kann, befinden sich im AusfĆ¼hrungsbeispiel sowohl in Anzahl als auch im Hinblick auf deren Formgebung lediglich beispielhaft vier Kochzonen 4, 5, 6 und 7. Die im Hinblick auf ihre AusmaƟe kenntlich gemachten Kochzonen 4 bis 7 kƶnnen durch nicht dargestellte Heizeinheiten, wie Strahlungsheizkƶrper oder Induktoren beheizt werden, so dass auf den Kochzonen 4 bis 7 abgestellte ZubereitungsgefƤƟe, in denen das Gargut enthalten ist, erhitzt werden kƶnnen.In Fig. 1 is a plan view of a hob 1 is shown, which has a hob plate 2. On an upper side or control surface 3 of the hob plate 2, which may be formed, for example, glass ceramic or glass, are in the embodiment both in number and in terms of their design, for example only four cooking zones 4, 5, 6 and 7. The with respect Cooking zones 4 to 7 identified by their dimensions can be heated by heating units (not shown), such as radiant heaters or inducers, so that preparation vessels placed on the cooking zones 4 to 7 and containing the food to be cooked can be heated.

DarĆ¼ber hinaus umfasst das Kochfeld 1 eine Bedienvorrichtung 8. Die Bedienvorrichtung 8 umfasst zumindest ein berĆ¼hrsensitives Bedienfeld 9. DarĆ¼ber hinaus sind weitere Felder gezeigt, die zur Anzeige von Informationen dargestellt sind. In diesem Zusammenhang sind die einer Anzeigeeinheit 10 zugeordneten Bereiche 11, 12, 13 und 14 genannt.In addition, the hob 1 comprises an operating device 8. The operating device 8 comprises at least one touch-sensitive control panel 9. In addition, further fields are shown, which are shown for displaying information. In this connection, the areas 11, 12, 13 and 14 assigned to a display unit 10 are mentioned.

DarĆ¼ber hinaus umfasst die auf der Kochfeldplatte 2 ausgebildete Anzeigeeinheit 10 einen Displaybereich 15. Im Unterschied zu den Bereichen 11, 12, 13 und 14, in denen bereits fest eingezeichnete Symbole lediglich hinterleuchtet werden kƶnnen, ist auf dem Displaybereich 15 die Anzeige von sich Ƥndernden Werten und/oder von sich verƤndernden Symbolen oder generell der Wechsel von Symbolanzeigen mƶglich.In addition, the display unit 10 formed on the cooktop panel 2 comprises a display area 15. In contrast to the areas 11, 12, 13 and 14, in which already firmly drawn symbols can only be backlit, on the display area 15 is the display of changing values and / or of changing symbols or in general the change of symbol displays possible.

Die Bedienvorrichtung 8 umfasst darĆ¼ber hinaus ein einziges mittels Magnetkraft auf der als KochflƤche ausgebildeten BedienflƤche 3 haltbares Bedienelement 16. Dieses ist zylinderfƶrmig bzw. diskusfƶrmig ausgebildet. Es ist um eine senkrecht zur Figurenebene stehende Achse drehbar. Das Bedienelement 16 kann als Dreh-Bedienknebel oder aber auch als Dreh-Kipp-Bedienknebel ausgebildet sein. Im Hinblick auf die spezifische Position, an der das Bedienelement 16 auf die BedienflƤche 3 aufsetzbar und magnetisch haltbar ist, ist im AusfĆ¼hrungsbeispiel derjenige Bereich Ć¼ber dem Display 15 vorgesehen. Dies bedeutet, dass zur FunktionsfƤhigkeit und somit zum magnetischen Halten einerseits und zur Betriebsbedingungseinstellung andererseits durch relatives Bewegen des Bedienelements 16 relativ zur Kochfeldplatte 2 nur diese spezifische Position vorgesehen ist.The operating device 8 further comprises a single by means of magnetic force on the cooking surface designed as a cooking surface 3 durable control element 16. This is cylindrical or discus-shaped. It is rotatable about an axis perpendicular to the plane of the figure. The control element 16 can as a rotary control knob or also be designed as a turn-tilt control knob. With regard to the specific position at which the operating element 16 can be placed on the operating surface 3 and magnetically durable, in the exemplary embodiment that area above the display 15 is provided. This means that for functioning and thus for magnetic holding, on the one hand, and for operating condition adjustment, on the other hand, by relative movement of the operating element 16 relative to the hob plate 2, only this specific position is provided.

Das Bedienelement 16 umfasst ein VergrĆ¶ĆŸerungselement 17, welches als Lupe ausgebildet ist. Durch diese Ausgestaltung wird erreicht, dass genau dann, wenn das Bedienelement 16 auf seine spezifisch vorgesehene Position zur vollstƤndigen FunktionserfĆ¼llung auf die BedienflƤche 3 aufgesetzt wird, auf dem Display 15 etwaig angezeigte Werte und/oder Symbole durch den komplett lichtdurchlƤssigen Bereich des Bedienelements 16 zum Durchtreten durch das VergrĆ¶ĆŸerungselement 17 vergrĆ¶ĆŸert dargestellt sind. Ein Nutzer oder Beobachter, der somit das Bedienelement 16 von oben betrachtet, kann die Anzeige auf dem Display 15 somit vergrĆ¶ĆŸert wahrnehmen. Im AusfĆ¼hrungsbeispiel ist diesbezĆ¼glich beispielhaft die Zahl 8 einer Sieben-SegmentAnzeige durch das Bedienelement 16 hindurch einfach zu erkennen und darĆ¼ber hinaus durch das VergrĆ¶ĆŸerungselement 17 vergrĆ¶ĆŸert. Die VergrĆ¶ĆŸerung im Vergleich zur ursprĆ¼nglichen GrĆ¶ĆŸe auf dem Display 15 ist zwischen einem Faktor grĆ¶ĆŸer 1 und kleiner 5.The operating element 16 comprises a magnifying element 17, which is designed as a magnifying glass. This configuration ensures that precisely when the operating element 16 is placed on its specific intended position for full functional performance on the operating surface 3, values and / or symbols possibly displayed on the display 15 pass through the completely transparent area of the operating element 16 are shown enlarged by the magnifying element 17. A user or observer thus viewing the operating element 16 from above can thus perceive the display on the display 15 enlarged. In the exemplary embodiment, in this regard, the number 8 of a seven-segment display can be easily recognized by the operating element 16 and, moreover, enlarged by the enlarging element 17. The magnification compared to the original size on the display 15 is between a factor greater than 1 and less than 5.

Das Bedienelement 16 umfasst darĆ¼ber hinaus einen Ring 18. Dieser dient einerseits zur Halterung des VergrĆ¶ĆŸerungselements 17. Andererseits ist dieser Ring 18 ein Magnet oder aus einem magnetisierbaren Material, so dass in Wechselwirkung mit Sensoren unter der Kochfeldplatte 2 die Relativbewegung des Bedienelements 16 bzw. dessen Position detektierbar ist und die damit gewĆ¼nschte Betriebsbedingungseinstellung 10 erfasst werden kann.On the other hand, this ring 18 is a magnet or of a magnetizable material, so that in interaction with sensors under the cooktop plate 2, the relative movement of the control element 16 and dessen Position can be detected and thus desired operating condition setting 10 can be detected.

Im Unterschied zur Ausgestaltung in Fig. 1 kann auch vorgesehen sein, dass das Bedienelement 16 selbst eine integrierte Anzeigeeinheit aufweist, welche zur Darstellung von Informationen in Form von Werten und/oder Buchstaben und/oder Symbolen ausgebildet ist. So kann dann im Unterschied zur Ausgestaltung gemƤƟ Fig. 1 nicht nur anstatt dazu zu einem vƶlligen Hindurchscheinen durch das Bedienelement in Richtung der LƤngsachse A selbst ein Anzeigen von Informationen, die in dem Bedienelement 16 selbst generiert wurden, in vergrĆ¶ĆŸerter Weise erfolgen. Vorzugsweise ist dann das VergrĆ¶ĆŸerungselement 17 direkt Ć¼ber der Anzeigeeinheit 10 des Bedienelements 16 positioniert.In contrast to the design in Fig. 1 can also be provided that the control element 16 itself has an integrated display unit, which is designed to display information in the form of values and / or letters and / or symbols. So then in contrast to the embodiment according to Fig. 1 not only instead to a complete show through the control in the direction the longitudinal axis A itself is an enlarged display of information that was generated in the control 16 itself. Preferably, the magnifying element 17 is then positioned directly above the display unit 10 of the operating element 16.

In Fig. 2 ist in vereinfachter schematischer Darstellung das Bedienelement 16 gezeigt. Es weist im oberen Bereich eine Vertiefung 19 auf, in welcher das VergrĆ¶ĆŸerungselement 17 angeordnet ist. DarĆ¼ber hinaus ist der umlaufende Ring 18 zu erkennen, welcher quasi als Hohlzylinder ausgebildet ist. Er erstreckt sich insbesondere Ć¼ber die gesamte Hƶhe des Bedienelements 16. Das Bedienelement 16 umfasst an einer Oberseite 21 einen Anzeigebereich 22, der das VergrĆ¶ĆŸerungselement 17 aufweist. Das VergrĆ¶ĆŸerungselement 17 ist vorzugsweise nach oben hin von einem Verkratzschutzelement 23 abgedeckt. Dies kann beispielsweise eine durchsichtige Folie sein.In Fig. 2 is shown in a simplified schematic representation of the control element 16. It has in the upper part of a recess 19 in which the magnifying element 17 is arranged. In addition, the circumferential ring 18 can be seen, which is formed quasi as a hollow cylinder. In particular, it extends over the entire height of the operating element 16. The operating element 16 comprises on a top side 21 a display region 22 which has the enlarging element 17. The enlarging element 17 is preferably covered at the top by a scratch protection element 23. This can be, for example, a transparent film.

Die LƤngsachse A des Bedienelements 16 ist ebenfalls dargestellt. Das Bedienelement 16 kann auch aus einer oberen und einer unteren Abdeckung bestehen, die gemeinsam ein geschlossenes Bedienelement 16 bilden. Dann ist im Bereich der oberen Abdeckung die Vertiefung 19 mit dem VergrĆ¶ĆŸerungselement 17 ausgebildet. Eine obere und eine untere Abdeckung kƶnnen lƶsbar, beispielsweise durch eine Rastverbindung verbunden sein. Im Inneren des Bedienelements 16 kƶnnen dann der Haltemagnet und mehrere Funktionsmagnete angeordnet sein. Die Funktionsmagnete kƶnnen dann in Verbindung mit dem Ring 18 zur Auswahl von Kochzonen 4 bis 7 und dann zur folgenden Betriebsparametereinstellung der ausgewƤhlten Kochzone 4 bis 7 vorgesehen sein.The longitudinal axis A of the operating element 16 is also shown. The operating element 16 may also consist of an upper and a lower cover, which together form a closed operating element 16. Then, in the region of the upper cover, the depression 19 is formed with the enlarging element 17. An upper and a lower cover can be releasably connected, for example by a latching connection. Inside the control element 16 then the holding magnet and a plurality of functional magnets can be arranged. The functional magnets may then be provided in conjunction with the ring 18 for selecting cooking zones 4 through 7 and then for subsequent operating parameter setting of the selected cooking zone 4 through 7.

Der Ring 18 kann sich auch nur teilweise Ć¼ber die gesamte Hƶhe des Bedienelements 16 erstrecken. Bei einem Dreh-Kipp-Bedienknebel ist eine Unterseite 20 uneben ausgebildet, so dass ein Kippen auch in einem Winkel zur Vertikalachse gegeben ist.The ring 18 may also extend only partially over the entire height of the control element 16. In a turn-tilt control knob, a bottom 20 is formed uneven, so that a tilt is also given at an angle to the vertical axis.
