Patent application number | Description | Published |
20110240632 | COOK-TOP HAVING AT LEAST THREE HEATING ZONES - A cook-top or hob includes multiple inductors and at least three heating zones which are operated by the inductors. A single power electronics subassembly supplies the inductors with heating current and includes a common rectifier which is operably connected to the inductors for rectifying an alternating current supplied by a single phase of a household electrical system. | 10-06-2011 |
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 |
20120205365 | COOK TOP COMPRISING AT LEAST TWO HEATING ELEMENTS AND A POWER ELECTRONICS ARRANGEMENT - A cook top with at least two heating elements includes a power electronics arrangement connected to a domestic single phase AC supply. The power electronics arrangement includes several power supply units, which each supply heating currents to one or more heating elements, and a switch arrangement with several electromechanical relays for connecting/disconnecting the power supply units to/from the heating elements. Output poles of at least two electromechanical relays associated with different power supply units are connected in parallel, wherein the parallel connection is permanently connected to at least one of the heating elements. This arrangement reduces the number of switching processes required for alternating use of a power supply device with several heating elements, and simplifies compliance with electromagnetic compatibility standards. | 08-16-2012 |
20130043239 | HOB DEVICE - A cooktop apparatus, in particular an induction cooktop apparatus, includes a switching unit configured to interrupt and establish current flow from a current supply, a first switching element receiving the current flow during an operating process, a control apparatus, which controls the switching unit during the operating process such that the switching unit interrupts the current supply during a first time interval which has a duration of less than of half a period of the power supply voltage. The control apparatus causes the current supply to be connected during the operating process immediately before and immediately after the first time interval. The first switching element begins switching and ends switching during the first time interval. | 02-21-2013 |
20130087554 | COOKER HOB DEVICE - A cooker hob device, in particular to an induction cooker hob device, includes at least one switching unit and at least one control apparatus. In order to obtain a high degree of efficiency, the control apparatus is constructed to automatically prompt the at least one switching unit in at least one operating cycle to switch in at least one entire first time interval using at least one switching parameter having a value which changes at least substantially continuously. | 04-11-2013 |
20130206750 | HEATING APPARATUS - A heating apparatus, in particular a hob heating apparatus, with at least one heating connection for at least one heating element and at least one frequency unit. In order to provide a heating apparatus of the generic type with relatively high operational reliability, it is proposed that the heating apparatus comprises a protective unit, which is provided for determining the existence of a conducting path between the frequency unit and the at least one heating connection. | 08-15-2013 |
20140001883 | METHOD FOR ADJUSTING AN INRUSH CURRENT OF A DOMESTIC APPLIANCE, AND DOMESTIC APPLIANCE, IN PARTICULAR COOKING RANGE, COMPRISING A CONTROL UNIT FOR CARRYING OUT THE METHOD | 01-02-2014 |
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 |
