20150034630 | INDUCTION COOKING DEVICE FOR TEMPERATURE-CONTROLLED COOKING - A modular heat-retaining system for keeping food warm. The system contains a plurality of induction heat retaining units, each of which forms a heat-retaining area, and further contains a common power and control unit having a common power controller and a plurality of connection interfaces for individually connecting and individually activating the induction heat-retaining units. In addition, the heat-retaining system contains one or more operating units, wherein the induction heat-retaining units contain at least one induction coil as part of an induction resonant circuit for generating an alternating magnetic field. The power and control unit contains control means for individual activation of the induction heat-retaining units. | 02-05-2015 |
20140158678 | INDUCTION COOKING DEVICE FOR TEMPERATURE-CONTROLLED COOKING - The invention relates to a method for determining and regulating the temperature of an article with inductive properties which is heated inductively by means of an induction device, wherein the induction device contains an induction coil, means for producing an induction resonant circuit and a support element arranged above the induction coil and having a first side, which acts as support face for the article, and a second side, which is directed towards the inductive coil. At least one temperature sensor is fitted to the second side. The resonant frequency of the induction resonant circuit is measured via detection means and the temperature of the article is calculated from the measured resonant frequency, wherein the resonant frequency is related to the temperature of the article by virtue of a mathematical function, and the function is determined by determining at least two absolute temperature calibration values of the article at respectively different resonant frequencies. The temperature calibration values are calculated from temperature measured values of the sensor. | 06-12-2014 |
20120024842 | CIRCUIT ARRANGEMENT FOR AN INDUCTION COOKER, METHOD FOR OPERATING THE CIRCUIT ARRANGEMENT AND INDUCTION COOKER - A circuit arrangement for an induction cooking device and an induction cooking device with a circuit of this kind, wherein the circuit includes a resonant circuit with at least one induction coil for the inductive heating of an induction cooking dish and at least one capacitor, as well as a variable circuit element for the variation of the inductivity and/or the capacity of the resonant circuit. The variable circuit element in preference is a choke controllable with direct current and the switching circuit in preference is operated with a constant frequency. | 02-02-2012 |
