Definitions
- the invention relates to a hob with a plurality of arranged in a grid heating elements according to the preamble of claim 1.
- the cooktop comprises a control unit which evaluates a size and position of the cookware elements that can be detected, for example, by using the heating elements designed as inductors as inductive sensors.
- the control unit assigns a heating element or a plurality of heating elements to a detected cookware element.
- the heating elements associated with a cookware element form a heating zone in which the heating elements are operated in a coordinated manner.
- Such matrix or micro-module cooktops are therefore characterized by the fact that there is no fixed well level with fixed or possibly within narrow limits variable heating zones.
- cover plates for such hobs therefore have no printing that would represent a size and / or position of heating zones. Therefore, markings of the cover plate in such cooktops usually refer to touch sensors of the user interface, light-emitting diodes or the like.
- heating elements in generic hobs for cost reasons have a diameter which is typically between 5 and 15 cm.
- the coupling of the inductors depends strongly on a degree of overlap between the bottom of the cookware element and the inductors.
- the effective heating power or cooking hob efficiency which can cover only a small number of less than three or four heating elements, is highly dependent on the position of the cooking utensil.
- the invention is in particular the object of making a hob of the generic type, in particular for small cookware elements more effectively usable.
- the invention is based on a hob with a plurality of arranged in a grid heating elements, a cover plate and a control unit.
- the control unit is designed to form a flexibly definable heating zone from one or more heating elements depending on a size and / or position of a cooking utensil element set up on the cover plate.
- the cover plate has at least one marking which visualizes the position of at least one heating zone preferred for small cookware elements.
- the position of the preferred heating zone can be determined by marking a center of the heating zone, visualizing one for heating small cookware elements preferred group of heating elements or by printing a circumferential circle of the heating zone.
- the marking is intended in particular to assist the user in centering the cooking utensil element with respect to a point of symmetry of the grid of the heating elements.
- This point of symmetry may be in advantageous embodiments of the invention, the position of the heating elements under the cover plate, in particular the center of a heating element.
- the heating zone preferred for small cookware elements may be formed from a group of heating elements arranged in an equiangular polygon. If the grid is a rectangular grid, then, for example, cookware elements that can cover a mesh of this grid with four heating elements arranged in a square can then preferably be set up so that a pot center coincides with a center of the quadrangle formed by the heating elements.
- the marking may represent a center of a group of three heating elements arranged in an equiangular triangle.
- This center can of course also be visualized by the representation of the three heating elements themselves, by a circle or by a cross.
- the marking is preferably arranged in a corner region of the cover plate.
- a corner region is a group of heating elements in particular may be designated if one or more of these heating elements are arranged on the edge of the hob.
- the heating elements are arranged in the region of the marking with smaller distances from each other in a grid with a smaller mesh size than in the other areas of the hob.
- heating zones in a close-meshed grid can be defined flexibly, especially for small cookware elements, and thus reproduce the shape and size of the cooking utensil element with a high degree of accuracy, while for larger cookware elements a coarse meshed one Figure is sufficient, so that for cost reasons larger inductors or heating elements can be used.
- control unit can be designed to apply different cookware detection methods in the region of the marking and in the remaining regions of the hob. For example, if a cookware element has been detected in the region of the mark, a simplified method may be activated which determines, for example, only the radius of the cookware element or, alternatively, without further detection of the size and shape of the cookware element, a predetermined group of heating elements or a single heating element of a heating zone associated with this cooking utensil.
- Fig. 1 shows a cooktop with a plurality of arranged in a rectangular grid and formed as inductors 10 heating elements.
- the inductors 10 are covered by a cover plate 12, on which cooking pots 14, 16 or other cookware elements are placed.
- a control unit 18 evaluates signals of a detection device, not shown here, which comprises the inductors 10 and thus detects the cooking pots 14, 16.
- the control unit 18 sums all or part of one of Cooking pots 14, 16 covered inductors 10 to flexibly definable heating zones 20, 22 together.
- the inductors 10 are operated in a synchronized manner, ie at the same heating frequency or at heating frequencies which do not generate hum.
- the cover plate 12 includes a marker 24 that visualizes a position of a heating zone 26 that is particularly suitable for heating small cookware elements 16.
- the heating zone 20 associated with the small cooking pot 16 comprises only one inductor 10. It would be more effective to place the cooking pot 16 centrally between four in-square inductors 10.
- the mark 24 lies in such a center in a corner region of the hob.
- Inductors 10 shown in dashed lines with thin lines are not visible in a real cooktop since the cover plate 12 is opaque.
- the marking 24, which may be formed as a serigraphic print or as an engraving, is immediately recognizable to the user, so that he can set up a small pan 16 readily centered on this point of symmetry of the grid of the inductors 10.
- Fig. 2 shows the possible positioning of a cooking pot 16 in a rectangular grid of inductors 10.
- the in Fig. 2 Positioning shown with the pot center on the marker 24 in terms of the efficiency of the hob optimal. Larger cooking pots can be placed anywhere, while still smaller pans are best heated by only one inductor 10.
- the centers of all inductors 10 may be provided with corresponding markings which, in addition to or complementary to the mark 24 of the center of the inductor 10a-10d formed square in Fig. 2 can be applied to the cover plate 12 or incorporated into the cover plate 12.
- Fig. 3 shows an alternative embodiment of the invention with a skewed grid of inductors 10.
- Each three adjacent inductors 10a, 10b, 10c are arranged in an equiangular triangle and a marker 24 visualizes the center of such a triangle.
- a marker 24 visualizes the center of such a triangle.
- centering on the mark 24 is preferred in view of the efficiency of the cooking flute.
- Smaller cooking pots are preferably placed on a single inductor 10a, 10b, 10c, while cooking pots whose diameter is greater than 2 or 3 times the spacing of adjacent inductors 10a, 10b, 10c can be freely positioned.
- FIG. 4a shows a marker 24, which consists of concentric circles and thus can visualize the center of a heating zone or an inductor 10.
- Fig. 4b shows three circles arranged in an equiangular triangle, which can visualize a group of three heating elements 10a, 10b, 10c which are preferred for heating small cookware elements 16.
- the marker 24 is a simple circle that may be either concentric with a center of an inductor 10 or with another symmetry point of the grid.
- the mark 24 according to Fig. 4c may advantageously have a diameter corresponding to the diameter of an inductor 10.
- FIG. 12 shows a marker 24 in the shape of a cross which may also be used to visualize the center of an inductor 10 or other point of symmetry (eg, the center of an equiangular polygon of inductors 10).
- the control unit 18 may be designed to control a display (not shown) and, whenever a particularly small diameter cooking pot has been detected, prompt the user to place this cooking pot in the heating zone 26 preferred for small cookware elements. For example, "Please set the cooking pot on the mark” on the display together with a pictogram of the mark.
- Fig. 5 shows a cover plate of a hob with two different markings, wherein a first mark 24a visualizes a heating zone, which is designed for setting up small cookware elements, similar to those in FIGS. 2 and 3 illustrated situations of three or four inductors can be heated.
- a second mark 24b visualizes a preferred for very small cooking pots heating zone in which the cooking pots are heated only by a single inductor 10.
- the heating zone visualized by the mark 24b is particularly suitable for cooking pots having a diameter which is in the range of a distance between adjacent inductors 10.
- Fig. 6 shows a further alternative embodiment of the invention, in which a portion 28 of the hob is equipped with smaller inductors 10a than the other areas of the hob.
- the inductors 10a in the area 28 are also arranged in a grid with a smaller mesh size, so that the area 28 allows a fine-mesh adaptation of heating zones to the shape of small cookware elements.
- the control unit 18 may use a simplified cookware detection algorithm when a cooking pot has been detected in the region of the marker 24.
- the control unit 18 for example, assume that in any case four (in hobs of the in Fig. 2 shown type) or three (in hobs of the in Fig. 3 shown type) inductors 10 associated with this cookware element. A radius of the cookware element then does not have to be detected. In this case, even if the radius is detected, the control unit 18 can simplify the assumption that the cookware element has been positioned centrally on the marking 24.

Abstract
Description
Die Erfindung betrifft ein Kochfeld mit einer Vielzahl von in einem Raster angeordneten Heizelementen nach dem Oberbegriff des Anspruchs 1.The invention relates to a hob with a plurality of arranged in a grid heating elements according to the preamble of claim 1.
In klassischen Strahlungskochfeldern ist es bekannt, eine Abdeckplatte aus Glas oder Glaskeramik mit Siebdruckmustern zu versehen, die eine Position von unter der Abdeckplatte angeordneten Heizelementen und damit die Größe und Position von festgelegten Heizzonen darstellen. Da im Bereich von Kochfeldern meistens kostengünstige schwarze Glaskeramik verwendet wird, die fast vollständig undurchsichtig ist, kann der Benutzer dadurch die Position der unterhalb der Abdeckplatte angeordneten Heizelemente nicht oder nur sehr schwer erkennen und Kochtöpfe oder Pfannen symmetrisch zu diesen Heizelementen ausrichten.In classical radiant panels, it is known to provide a cover plate made of glass or glass ceramic with screen printing patterns that represent a position of arranged under the cover heating elements and thus the size and position of specified heating zones. Since in the field of hobs usually cost black glass ceramic is used, which is almost completely opaque, the user can not or very difficult to detect the position of the arranged below the cover plate heating elements and align cooking pots or pans symmetrically to these heating elements.
Insbesondere im Bereich der Induktionskochfelder werden jedoch neuerdings auch so genannte Matrix-Kochfelder angeboten, in denen eine Vielzahl von Heizelementen gleicher Bauart in einem Raster angeordnet ist. Das Kochfeld umfasst eine Steuereinheit, die eine Größe und Position der Kochgeschirrelemente auswertet, die beispielsweise durch die Verwendung der als Induktoren ausgebildeten Heizelemente als induktive Sensoren detektiert werden können. Die Steuereinheit ordnet einem detektierten Kochgeschirrelement ein Heizelement oder mehrere Heizelemente zu. Die einem Kochgeschirrelement zugeordneten Heizelemente bilden eine Heizzone, in welcher die Heizelemente in einer aufeinander abgestimmten Weise betrieben werden. Solche Matrix- oder Mikromodul-Kochfelder sind demnach dadurch charakterisiert, dass es keinen festgelegten Muldenspiegel mit festgelegten oder allenfalls in engen Grenzen variablen Heizzonen gibt. In der Regel weisen Abdeckplatten für solche Kochfelder daher keine Bedruckung auf, die eine Größe und/oder Position von Heizzonen darstellen würde. Markierungen der Abdeckplatte beziehen sich daher in solchen Kochfeldern in der Regel auf Touch-Sensoren der Benutzerschnittstelle, Leuchtdioden oder dergleichen.Especially in the field of induction hobs, however, so-called matrix hobs are now also offered in which a plurality of heating elements of the same type is arranged in a grid. The cooktop comprises a control unit which evaluates a size and position of the cookware elements that can be detected, for example, by using the heating elements designed as inductors as inductive sensors. The control unit assigns a heating element or a plurality of heating elements to a detected cookware element. The heating elements associated with a cookware element form a heating zone in which the heating elements are operated in a coordinated manner. Such matrix or micro-module cooktops are therefore characterized by the fact that there is no fixed well level with fixed or possibly within narrow limits variable heating zones. As a rule, cover plates for such hobs therefore have no printing that would represent a size and / or position of heating zones. Therefore, markings of the cover plate in such cooktops usually refer to touch sensors of the user interface, light-emitting diodes or the like.
Obwohl natürlich zur optimalen Anpassung der Form und Größe der Heizzone an den Boden des Kochgeschirrelements sehr kleine Heizelemente bzw. ein sehr engmaschiges Raster von Heizelementen vorteilhaft wäre, haben Heizelemente in gattungsgemäßen Kochfeldern aus Kostengründen einen Durchmesser, der typischerweise zwischen 5 und 15 cm liegt. Insbesondere in Induktionskochfeldern hängt die Ankopplung der Induktoren stark von einem Überlappungsgrad zwischen dem Boden des Kochgeschirrelements und den Induktoren ab. Dies führt dazu, dass die effektive Heizleistung bzw. der Wirkungsgrad des Kochfelds für kleine Kochtöpfe, die nur eine geringe Zahl von weniger als drei oder vier Heizelementen überdecken können, stark von der Position des Kochgeschirrelements abhängt. Wenn beispielsweise ein sehr kleiner Kochtopf, dessen Durchmesser im Wesentlichen dem Durchmesser eines Heizelements entspricht, zentriert auf dieses Heizelement aufgestellt wird, kann eine sehr große Heizleistung in den Boden des Kochgeschirrelements eingekoppelt werden, während dies nicht der Fall ist, wenn der Boden des Kochgeschirrelements im Wesentlichen einen Zwischenraum zwischen mehreren Heizelementen überdeckt. Da die Induktoren bzw. Heizelemente jedoch häufig nicht unmittelbar durch die Abdeckplatte erkennbar sind, ist es für den Benutzer sehr schwierig, eine optimale Position für kleine Kochgeschirrelemente zu finden.Although, of course, to optimally adapt the shape and size of the heating zone to the bottom of the cooking utensil, very small heating elements or a very close-meshed Grid of heating elements would be advantageous heating elements in generic hobs for cost reasons have a diameter which is typically between 5 and 15 cm. Especially in induction hobs, the coupling of the inductors depends strongly on a degree of overlap between the bottom of the cookware element and the inductors. As a result, the effective heating power or cooking hob efficiency, which can cover only a small number of less than three or four heating elements, is highly dependent on the position of the cooking utensil. For example, if a very small saucepan, whose diameter is substantially equal to the diameter of a heating element, is centered on this heating element, a very high heating power can be coupled into the bottom of the cooking utensil, while this is not the case if the bottom of the cooking element is in the Substantially covers a gap between several heating elements. However, since the inductors or heating elements are often not directly visible through the cover plate, it is very difficult for the user to find an optimal position for small cookware elements.
Der Erfindung liegt insbesondere die Aufgabe zugrunde, ein Kochfeld der gattungsgemäßen Art insbesondere für kleine Kochgeschirrelemente effektiver nutzbar zu machen.The invention is in particular the object of making a hob of the generic type, in particular for small cookware elements more effectively usable.
Die Aufgabe wird gelöst durch die Merkmale des Anspruchs 1. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.The object is solved by the features of claim 1. Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.
Die Erfindung geht aus von einem Kochfeld mit einer Vielzahl von in einem Raster angeordneten Heizelementen, einer Abdeckplatte und einer Steuereinheit. Die Steuereinheit ist dazu ausgelegt, abhängig von einer Größe und/oder Position eines auf die Abdeckplatte aufgestellten Kochgeschirrelements aus einem oder mehreren Heizelementen eine flexibel definierbare Heizzone zu bilden.The invention is based on a hob with a plurality of arranged in a grid heating elements, a cover plate and a control unit. The control unit is designed to form a flexibly definable heating zone from one or more heating elements depending on a size and / or position of a cooking utensil element set up on the cover plate.
Um das Auffinden einer optimalen Position für kleine Kochgeschirrelemente zu erleichtern, wird vorgeschlagen, dass die Abdeckplatte wenigstens eine Markierung aufweist, welche die Position wenigstens einer für kleine Kochgeschirrelemente bevorzugten Heizzone visualisiert. Die Position der bevorzugten Heizzone kann durch das Markieren eines Mittelpunkts der Heizzone, das Visualisieren einer zum Beheizen von kleinen Kochgeschirrelementen bevorzugten Gruppe von Heizelementen oder durch das Aufdrucken eines Umfangskreises der Heizzone erfolgen.In order to facilitate the finding of an optimum position for small cookware elements, it is proposed that the cover plate has at least one marking which visualizes the position of at least one heating zone preferred for small cookware elements. The position of the preferred heating zone can be determined by marking a center of the heating zone, visualizing one for heating small cookware elements preferred group of heating elements or by printing a circumferential circle of the heating zone.
Die Markierung soll insbesondere dazu dienen, dem Benutzer das Zentrieren des Kochgeschirrelements bezüglich eines Symmetriepunktes des Rasters der Heizelemente zu erleichtern. Dieser Symmetriepunkt kann in vorteilhaften Ausgestaltungen der Erfindung die Position eines der Heizelemente unter der Abdeckplatte sein, insbesondere der Mittelpunkt eines Heizelements. Ferner kann die für kleine Kochgeschirrelemente bevorzugte Heizzone aus einer Gruppe von Heizelementen gebildet sein, die in einem gleichwinkligen Vieleck angeordnet sind. Wenn das Raster ein rechtwinkliges Raster ist, können dann beispielsweise Kochgeschirrelemente, die eine Masche dieses Rasters mit vier in einem Quadrat angeordneten Heizelementen überdecken können, bevorzugt so aufgestellt werden, dass ein Topfmittelpunkt mit einem Mittelpunkt des von den Heizelementen gebildeten Vierecks zusammenfällt.The marking is intended in particular to assist the user in centering the cooking utensil element with respect to a point of symmetry of the grid of the heating elements. This point of symmetry may be in advantageous embodiments of the invention, the position of the heating elements under the cover plate, in particular the center of a heating element. Further, the heating zone preferred for small cookware elements may be formed from a group of heating elements arranged in an equiangular polygon. If the grid is a rectangular grid, then, for example, cookware elements that can cover a mesh of this grid with four heating elements arranged in a square can then preferably be set up so that a pot center coincides with a center of the quadrangle formed by the heating elements.
Insbesondere in dreieckigen Rastern, in denen benachbarte Heizelemente in einem gleichwinkligen Dreieck angeordnet sind, kann die Markierung einen Mittelpunkt einer Gruppe von drei in einem gleichwinkligen Dreieck angeordneten Heizelementen darstellen. Dieser Mittelpunkt kann natürlich auch durch die Darstellung der drei Heizelemente selbst, durch einen Kreis oder durch ein Kreuz visualisiert werden.In particular, in triangular grids in which adjacent heating elements are arranged in an equiangular triangle, the marking may represent a center of a group of three heating elements arranged in an equiangular triangle. This center can of course also be visualized by the representation of the three heating elements themselves, by a circle or by a cross.
Um für die restlichen Heizelemente des Kochfelds eine größtmögliche Flexibilität bei der Definition der Heizzonen beizubehalten, ist die Markierung vorzugsweise in einem Eckbereich der Abdeckplatte angeordnet. Als "in einem Eckbereich liegend" soll eine Gruppe von Heizelementen insbesondere kann bezeichnet werden, wenn eines oder mehrere dieser Heizelemente am Rand des Kochfelds angeordnet sind.In order to maintain the greatest possible flexibility in the definition of the heating zones for the remaining heating elements of the hob, the marking is preferably arranged in a corner region of the cover plate. As a "lying in a corner region" is a group of heating elements in particular may be designated if one or more of these heating elements are arranged on the edge of the hob.
In einer möglichen Ausgestaltung der Erfindung sind die Heizelemente im Bereich der Markierung mit geringeren Abständen zueinander in einem Raster mit einer kleineren Maschengröße angeordnet als in den übrigen Bereichen des Kochfelds. Dadurch können speziell für kleine Kochgeschirrelemente Heizzonen in einem engmaschigen Raster flexibel definiert werden und so mit einer hohen Genauigkeit die Form und Größe des Kochgeschirrelements abbilden, während für größere Kochgeschirrelemente eine grobmaschigere Abbildung ausreichend ist, so dass aus Kostengründen größere Induktoren bzw. Heizelemente eingesetzt werden können.In a possible embodiment of the invention, the heating elements are arranged in the region of the marking with smaller distances from each other in a grid with a smaller mesh size than in the other areas of the hob. As a result, heating zones in a close-meshed grid can be defined flexibly, especially for small cookware elements, and thus reproduce the shape and size of the cooking utensil element with a high degree of accuracy, while for larger cookware elements a coarse meshed one Figure is sufficient, so that for cost reasons larger inductors or heating elements can be used.
Ferner kann die Steuereinheit dazu ausgelegt sein, im Bereich der Markierung und in den übrigen Bereichen des Kochfelds unterschiedliche Kochgeschirr-Detektionsverfahren anzuwenden. Wenn beispielsweise im Bereich der Markierung ein Kochgeschirrelement detektiert wurde, kann ein vereinfachtes Verfahren aktiviert werden, mit dem beispielsweise nur der Radius des Kochgeschirrelements bestimmt wird oder alternativ ohne weitere Detektion der Größe und Form des Kochgeschirrelements eine vorgegebene Gruppe von Heizelementen oder ein einziges Heizelement einer Heizzone dieses Kochgeschirrelements zugeordnet werden.Furthermore, the control unit can be designed to apply different cookware detection methods in the region of the marking and in the remaining regions of the hob. For example, if a cookware element has been detected in the region of the mark, a simplified method may be activated which determines, for example, only the radius of the cookware element or, alternatively, without further detection of the size and shape of the cookware element, a predetermined group of heating elements or a single heating element of a heating zone associated with this cooking utensil.
