20100206867 | COOKING DEVICE - A cooktop includes a plurality of heaters that form a contiguous cooking zone, a power supply for the plurality of heaters with a differentiator that differentiates between a first positive heating power for a first of the plurality of heaters and a second positive heating power for a second of the plurality of heaters in a differentiated heating mode. | 08-19-2010 |
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 |
20110163086 | COOKTOP AND METHOD FOR OPERATING A COOKTOP - A cooktop is provided that includes heating elements which are combined to a heating zone; a power supply to generate a heating current that operates the heating elements; a switch to open and close a power circuit that includes the power supply and one of the heating elements; and a controller that determines a characteristic variable of the heating current, actuates the switch as a function of a selected power level to operate the heating zone, and activates, in a first operating state, two of the heating elements, which are combined to form the heating zone, in different phases of a heating period. | 07-07-2011 |
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 |
20130342016 | DOMESTIC APPLIANCE HAVING A STAND-BY MODE AND METHOD FOR OPERATING SUCH A DOMESTIC APPLIANCE - A domestic appliance includes a mains connection at which an electrical mains voltage can be applied relative to a reference potential, a main supply unit supplying an electrical operating voltage from the mains voltage at its output, and at least one electrical consumer receiving the operating voltage. An electrical switch electrically isolates at least the output of the main supply unit from the mains connection, when the domestic appliance is in a standby mode. Provided separate from the main supply unit is a voltage supply which is coupled to the mains connection and which taps the mains voltage at the mains connection in the standby mode and supplies a supply voltage from the mains voltage for switching the electrical switch to an electrically conducting switching state to thereby switch the domestic appliance from the standby mode to an operating mode. | 12-26-2013 |
