Außerdem erlaubt sie die Nutzung der installierten Gesamtleistung und ihre Verwendung zur Speisung jeder der Spulen, so dass sie eine ultraschnelle Erwärmung mit einer Leistungskapazität, welche größer als die Nominalleistung der Spule ist, erlaubt, ohne die Nominalkennwerte des Systems zu erhöhen.The closest prior art to the invention is European patent application EP 0844807, which belongs to the same assignee as the present invention and which describes the best possible control of the power installed in domestic induction hobs with a reconfigurable topology which allows the independent supply of two coils, which are the heating elements, with a power adjustable up to their nominal values. In addition, it allows the use of the installed total power and its use for feeding each of the coils so that it allows ultrafast heating with a power capacity greater than the nominal power of the coil without increasing the nominal characteristics of the system.

BESCHREIBUNG DER ERFINDUNGDESCRIPTION OF THE INVENTION

Die vorliegende Erfindung hat die Aufgabe, ein Induktionskochfeld bereitzustellen, welches zumindest eine Heizzone umfasst, welche durch zwei unabhängige Heizzonen gebildet wird, wozu jeder von ihnen ein Induktionsheizelement zugeordnet ist, so dass eine oder zwei der Zonen in Abhängigkeit von der Größe des zu erwärmenden Behältnisses aktiviert werden können, und zwar derart, dass die maximale Heizleistung erhöht werden kann, um die Heizzeit zu verkürzen, wie zum Beispiel zum Verkürzen der Zeit, welche gebraucht wird, um ein erstes Aufkochen zu erreichen.The object of the present invention is to provide an induction hob comprising at least one heating zone formed by two independent heating zones, to which each of them is assigned an induction heating element, such that one or two of the zones depend on the size of the container to be heated can be activated in such a way that the maximum heating power can be increased to shorten the heating time, such as to shorten the time it takes to achieve a first boil.

Um die zuvor erwähnten Aufgaben zu erreichen, besteht die Erfindung aus einem neuen Induktionskochfeld von der Art, welche zumindest zwei Leistungsmodule umfasst, von welchen jedes eine elektrische Leistung zumindest einem ersten Induktionsheizelement und einem zweiten Induktionsheizelement zuführt, welchen jeweils eine Heizzone für ein Gargutbehältnis zugeordnet ist, welches Leistungsmodui zur Erhöhung der maximalen Heizleistung des ersten Induktionsheizelements die Energiezufuhr zu dem zweiten Induktionsheizelement unterbricht.In order to achieve the objects mentioned above, the invention consists of a new induction hob of the type comprising at least two power modules, each of which supplies an electrical power to at least a first induction heating element and a second induction heating element, each associated with a heating zone for a cooking product container in that the power module for increasing the maximum heating power of the first induction heating element interrupts the power supply to the second induction heating element.

Die wichtigste Neuheit der Erfindung beruht auf dem Merkmal, dass die Heizzonen der ersten Induktionsheizelemente der beiden Leistungsmodule zusammen eine gemeinsame Heizzone bilden und dass außerdem zur Erhöhung der maximalen Heizleistung in der gemeinsamen Heizzone die beiden Leistungsmodule ihre jeweilige Gesamtleistung den ersten Induktionsheizelementen bereitstellen, so dass die Heizzeit des Gargutbehältnisses beträchtlich verkürzt wird.The most important novelty of the invention is based on the feature that the heating zones of the first induction heating elements of the two power modules together form a common heating zone and, moreover, to increase the maximum heating power in the common heating zone, the two power modules provide their respective total power to the first induction heating elements, so that the Heating time of Gargutbehältnisses is considerably shortened.

In einer Ausführungsform der Erfindung ist die gemeinsame Heizzone als eine Heizzone mit zwei Kreisen verwirklicht, welchen eine äußere ringförmige Heizzone und eine innere Heizzone zugeordnet sind, welche je einem der beiden ersten Induktionsheizelemente zugeordnet sind.In one embodiment of the invention, the common heating zone is realized as a heating zone with two circuits, which are associated with an outer annular heating zone and an inner heating zone, which are each associated with one of the two first induction heating.

Die Erfindung sieht die Einbeziehung einer Einrichtung zur Erkennung des Behältnisses, wie zum Beispiel eines Topfes, vor, um die Größe der Bodenfläche eines auf der gemeinsamen Heizzone abgestellten Gargutbehältnisses zu bestimmen.The invention provides for the inclusion of a device for detecting the container, such as a pot, to determine the size of the bottom surface of a parked on the common heating zone Gargutbehältnisses.

In Abhängigkeit von der Größe, welche durch die Einrichtung zur Erkennung der Größe der Bodenfläche des Gargutbehältnisses erfassten wird, führen die beiden Leistungsmodule ihre Gesamtleistungen erst ab einer bestimmten Größe der Bodenfläche des Gargutbehältnisses den ersten Induktionsheizelementen der gemeinsamen Heizzone zu.Depending on the size, which is detected by the device for detecting the size of the bottom surface of the Gargutbehältnisses, lead the two power modules their overall performance only from a certain size of the bottom surface of the Gargutbehältnisses the first induction heating of the common heating zone.

Wenn die erfasste Größe der Bodenfläche des Gargutbehältnisses kleiner als eine bestimmte Größe ist, dann stellt nur eines der Leistungsmodule seine Gesamtleistung dem zugeordneten ersten Induktionsheizelement der gemeinsamen Heizzone bereit.If the detected size of the bottom surface of the food container is smaller than a certain size, then only one of the power modules will provide its total power to the associated first common heating zone induction heating element.

Außerdem sieht die Erfindung vor, die Erhöhung der maximalen Heizleistung eines der zweiten Induktionsheizelemente zu erlauben, wozu jedes der Leistungsmodule die Energiezufuhr zu dem jeweiligen ersten Induktionsheizelement unterbricht und seine Gesamtleistung dem zweiten Induktionsheizelement bereitstellt.In addition, the invention provides to allow the increase of the maximum heating power of one of the second induction heating elements, for which purpose each of the power modules interrupts the power supply to the respective first induction heating element and provides its total power to the second induction heating element.

Wie bereits erwähnt, betrifft die Erfindung auch ein Verfahren zur Erhöhung der maximalen Heizleistung von Heizzonen für Gargutbehältnisse in einem Induktionskochfeld, das zumindest zwei Leistungsmodule aufweist, wobei über jedes von ihnen eine elektrische Leistung zumindest einem ersten Induktionsheizelement und einem zweiten Induktionsheizelement zugeführt wird, denen jeweils eine der Heizzonen zugeordnet ist, welches Leistungsmodul zur Erhöhung der maximalen Heizleistung des ersten Induktionsheizelements die Energiezufuhr zu dem zweiten Induktionsheizelement unterbricht und seine Gesamtleistung dem ersten Induktionsheizelement bereitstellt, und ist dadurch gekennzeichnet, dass die Heizzonen der ersten Induktionsheizelemente der beiden Leistungsmodule zusammen eine gemeinsame Heizzone bilden, und dass außerdem zur Erhöhung der maximalen Heizleistung der gemeinsamen Heizzone den ersten Induktionsheizelementen die jeweilige Gesamtleistung der beiden Leistungsmodule zugeführt wird.As already mentioned, the invention also relates to a method for increasing the maximum heating power of heating zones for food containers in an induction hob, which has at least two power modules, wherein via each of them an electrical power is supplied to at least a first induction heating element and a second induction heating element, respectively one of the heating zones is assigned, which power module to increase the maximum heating power of the first induction heating interrupts the power supply to the second induction heating and provides its total power to the first induction heating, and is characterized in that the heating zones of the first induction heating of the two power modules together form a common heating zone , And that also to increase the maximum heating power of the common heating zone, the first induction heating the respective total power of the two power modules supplied becomes.

BESCHREIBUNG DER BEVORZUGTEN AUSFÜHRUNGSFORMDESCRIPTION OF THE PREFERRED EMBODIMENT

Im Anschluss erfolgt eine Beschreibung der Erfindung basierend auf der zuvor erörterten Figur.Following is a description of the invention based on the previously discussed figure.

Das Kochfeld des Ausführungsbeispiels der Erfindung umfasst zwei Leistungsmodule 1 und 3, von welchen jedes ersten Induktionsheizelementen 5 und 9 und zweiten Induktionsheizelementen 7 und 11 elektrische Leistung zuführen kann.The hob of the embodiment of the invention comprises two power modules 1 and 3, of which each first induction heating elements 5 and 9 and second induction heating elements 7 and 11 can supply electrical power.

Jedem der Induktionsheizelemente ist eine Heizzone eines Gargutbehältnisses 21, wie zum Beispiel eines Topfes, zugeordnet, so dass den ersten Heizelementen 5 und 9 die Heizzonen 13 beziehungsweise 15 zugeordnet sind und den zweiten Heizelementen 7 und 11 die Heizzonen 17 beziehungsweise 19 zugeordnet sind.Each of the induction heating elements is assigned a heating zone of a food container 21, such as a pot, so that the heating zones 13 and 15 are associated with the first heating elements 5 and 9 and the heating zones 17 and 19 are associated with the second heating elements 7 and 11.

Wie in der Figur zu sehen ist, stellt die Heizzone 15 eine äußere ringförmige Heizzone dar und stellt die Heizzone 13 eine innere kreisförmige Heizzone dar.As can be seen in the figure, the heating zone 15 is an outer annular heating zone and the heating zone 13 is an inner circular heating zone.

Diese Konfiguration erlaubt es, die Erwärmung eines Gargutbehältnisses 21, dessen Durchmesser größer als jener der inneren Heizzone 13 und kleiner als jener der äußeren Heizzone 15 ist, durchzuführen.This configuration makes it possible to perform the heating of a food container 21 whose diameter is larger than that of the inner heating zone 13 and smaller than that of the outer heating zone 15.

Falls es notwendig ist, das Gargutbehältnis 21 schnell zu erwärmen, wird die Gesamtleistung, welche durch jedes der beiden Leistungsmodule 1 und 3 bereitgestellt wird, den ersten Induktionsheizelementen 5 und 9 bereitgestellt, so dass die maximale Leistung, welche denselben bereitgestellt wird, erhöht wird und die Heizzeit des Gargutbehältnisses 21 beträchtlich verkürzt wird.If it is necessary to heat the food container 21 quickly, the total power provided by each of the two power modules 1 and 3 is provided to the first induction heating elements 5 and 9 so that the maximum power provided thereto is increased and the heating time of the Gargutbehältnisses 21 is considerably shortened.

Die Erfindung umfasst eine Einrichtung zur Erkennung der Größe der Bodenfläche des Gargutbehältnisses 21 (in den Figuren nicht dargestellt), welches durch Reihe von Sensoren gebildet werden kann, so dass die Gesamtleistungen der Leistungsmodule 1 und 2 der gemeinsamen Heizzone 23 nur dann zugeführt werden, wenn die Größe der Bodenfläche des Gargutbehältnisses einen Durchmesser aufweist, der größer als jener der inneren kreisförmigen Heizzone 13 ist, wie in der Figur zu erkennen ist.The invention comprises a device for detecting the size of the bottom surface of the food container 21 (not shown in the figures), which can be formed by series of sensors, so that the total power of the power modules 1 and 2 of the common heating zone 23 are supplied only if the size of the bottom surface of the Gargutbehältnisses has a diameter which is greater than that of the inner circular heating zone 13, as can be seen in the figure.

Falls die Größe des Bodens des Gargutbehältnisses 21 einen Durchmesser aufweist, welcher gleich jenem oder kleiner als jener der inneren Heizzone 13 ist, stellt nur eines der beiden Leistungsmodule 1 oder 3 seine Gesamtleistung dem Induktionsheizelement 5 der gemeinsamen Heizzone 23 bereit, da in diesem Fall auf Grund der kleineren Größe der Heizfläche ihre Erwärmung schneller erfolgt und es nicht notwendig ist, die Leistung beider Leistungsmodule 1 und 3 bereitzustellen.If the size of the bottom of the Gargutbehältnisses 21 has a diameter which is equal to or smaller than that of the inner heating zone 13, only one of the two power modules 1 or 3 provides its total power to the induction heating element 5 of the common heating zone 23, since in this case Due to the smaller size of the heating surface their heating is faster and it is not necessary to provide the power of both power modules 1 and 3.

Es besteht auch die Möglichkeit, dass gewünscht wird, die maximale Heizleistung eines der zweiten Induktionsheizelemente 7 oder 11 zu erhöhen, in welchem Fall die Energiezufuhr zu dem jeweiligen ersten Induktionsheizelement 5 oder 9 unterbrochen und seine Gesamtleistung dem zweiten Induktionsheizelement 7 oder 11 bereitgestellt wird.There is also the possibility that it is desired to increase the maximum heating power of one of the second induction heating elements 7 or 11, in which case the power supply to the respective first induction heating element 5 or 9 is interrupted and its total power is provided to the second induction heating element 7 or 11.
