| 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 |
| 20090294437 | Device for heating up a heating element - A device, in particular, for inductively heating up a heating element by means of an inductor and an element for recording a reference quantity which is dependent on the temperature of the heating element and derived from the electric quantity of the inductor in such a way that it makes it possible to form the reference value from the reference quantity and to adjust the temperature according to the reference quantity adjustment by means of the reference value. The aim of said invention is to carry out a reliable adjustment of a water temperature or of a cooked product even at extreme conditions or when the reference value is incorrect. For this purpose, the device comprises a correction means for correcting the reference value. | 12-03-2009 |
| 20090321424 | Cooking device - A cooking device, in particular a cooking device for induction hobs, the cooking device including a computation unit, the computation unit having at least one standby mode that is activated as a function of a removal of cookware from a cooking zone; and a warning signal output unit, the warning signal output unit outputting, during a period in which the standby mode has been activated, a warning signal in the event that cookware is again within the cooking zone. | 12-31-2009 |
| 20110226753 | HOB COMPRISING A VISUAL DISPLAY UNIT AND METHOD FOR OPERATING A HOB - A hob includes a visual display associating each heating zone on the hob with a control element in order to control heating zones that are variable. The visual display unit provides a user interface showing a pictogram of a heating zone that illustrates the position and/or the size of the heating zone, and a plurality of control elements are juxtaposed to the visual display unit. A detector detects the position and/or size of a cooking utensil. The control unit defines heating zones depending on the detected size and/or position of the cooking utensil element, associates one or more heating elements with the heating zone, and provides a symbol in the visual display that associates the pictogram of the heating zone with one of the control elements. | 09-22-2011 |
| 20110233195 | RADIATOR FOR A HOUSEHOLD APPLIANCE - A light-permeable hot plate includes at least one cavity which is filled with illuminant. The illuminant in the cavity can be excited to illuminate by an electromagnetic excitation field. The hot plate may be part of a household appliance which includes an induction hob with a cooking zone, with the hot plate being assigned to the at least one cooking zone for heating a cooking vessel placed on the cooking zone. | 09-29-2011 |
| 20110233196 | ILLUMINATED HOT PLATE - A light-permeable hot plate includes at least one cavity filled with illuminant. The illuminant in the cavity can be excited to illuminate by an electromagnetic excitation field. The hot plate can be part of an induction hob, with the at least one cavity being arranged in a region of a cooking zone. The electromagnetic excitation field is provided to transfer energy into a household appliance which is arranged on the cooking zone. | 09-29-2011 |
| 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 |
| 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 |
