Patent application number | Description | Published |
20090139980 | Cooking Hob and Method for the Operation of a Cooking Hob - A cooking hob, especially an induction cooking hob, including a first heating zone having at least two independently heatable heating elements operable by a first power supply via a first switching device, and at least one additional heating zone operable by a second power supply via a second switching device in a normal mode of operation. The heating capacity of the first heating zone can be increased beyond a maximum power of the first power supply while the first heating zone and the additional heating zone are operated simultaneously in the normal mode of operation. The cooking hob includes a switching element for establishing a power supply connection between the second power supply and one of the heating elements of the first heating zone in a special mode of operation so as to increase the heating capacity of the first heating zone. | 06-04-2009 |
20100282740 | INDUCTION HOB COMPRISING A PLURALITY OF INDUCTION HEATERS - An induction hob having a plurality of induction heating elements; a control unit to operate the plurality of induction heating elements so as to heat at least one flexibly definable heating zone in a synchronized manner; and a measurement array to measure a heating power generated by the plurality of induction heating elements. The measurement array measures a sum of heating powers of at least two induction heating elements and the control unit uses the sum of heating powers to regulate the heating power generated by the plurality of induction heating elements. | 11-11-2010 |
20110226756 | COOKING HOB WITH SEVERAL HEATING ELEMENTS AND AT LEAST ONE POWER ELECTRONICS SUBASSEMBLY - A cooking hob, in particular an induction hob, includes several heating elements, at least one power electronics subassembly for generating a heating current for operating the heating elements, and a switching arrangement for making and breaking a connection between the power electronics assembly and the heating elements. The switching arrangement is constructed as an assembly that is separate from the power electronics assembly. | 09-22-2011 |
20110233199 | HOB HAVING AT LEAST ONE INDUCTOR, AT LEAST ONE INVERTER AND A SWITCHING APPARATUS - A hob having at least one inductor, at least one inverter, a switching apparatus and a detection circuit for detection of cooking utensils. The switching apparatus is arranged in a circuit between the inductor and the inverter and switchable between a first switch position in which a connection between the inverter and the inductor is established and a second switch position in which the connection between the inverter and the inductor is interrupted. In order to allow an energy-saving detection mode, the switching apparatus is connected to the detection circuit such that the switching apparatus connects the inductor to the detection circuit when it is in the second switch position. | 09-29-2011 |
20110272397 | HOB HAVING AT LEAST ONE HEATING ZONE HAVING SEVERAL HEATING ELEMENTS - A hob includes at least one heating zone having several heating elements, a user interface for setting a heating capacity of the heating zone, and a control unit for operating the heating elements and for distributing the heating capacity among the heating elements according to a heating capacity distribution. In order to improve the efficiency of the hob, the control unit is configured to distribute the heating capacity among a larger number of heating elements when the heating capacity is below a threshold value than in the case, when the heating capacity is above the threshold value. | 11-10-2011 |
20120024835 | COOKTOP HAVING A DETECTION ASSEMBLY AND METHOD FOR OPERATING A COOKTOP - A cooktop includes a plurality of heating elements, a user interface for inputting a power level, a detection assembly for detecting a position and size of at least one cookware element, and a control unit designed to combine a plurality of heating elements into a heating zone depending on the detected size and position of the cookware element and to operate the heating elements of the heating zone with a total heat output. In order to ensure a reproducible total heat output, the control unit is designed to calculate a bottom surface of the cookware element from the measurands of the detection assembly and to determine the total heat output depending on power level and bottom surface. | 02-02-2012 |
20120125918 | HOTPLATE HAVING AT LEAST TWO HEATING ZONES - A hotplate apparatus, in particular for a hotplate having a cover plate having at least two heating zones, includes a cooking utensil sensor unit. The cooking utensil sensor unit has at least one bridging detection unit, which is intended to detect at least bridging of the at least two heating zones by at least one cooking utensil element. | 05-24-2012 |
20140067095 | COOKING APPLIANCE - A cooking appliance apparatus includes a power unit, and a communication unit which is configured to receive at least one information item from a data network. A control unit is operably connected to the communication unit and configured to change at least one operating parameter of the power unit at least as a function of the at least one information item. | 03-06-2014 |
