Publication number: 20150034630Abstract: 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.Type: ApplicationFiled: January 5, 2012Publication date: February 5, 2015Applicant: INDUCS AGInventor: Christian Fuchs

Publication number: 20140158678Abstract: 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.Type: ApplicationFiled: December 28, 2011Publication date: June 12, 2014Applicant: Inducs AGInventors: Albert Thomann, Andreas Vogel, Christian Fuchs

Publication number: 20120024842Abstract: 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.Type: ApplicationFiled: April 28, 2011Publication date: February 2, 2012Applicant: INDUCS AGInventors: Albert Thomann, Christian Fuchs, Martin Behle

Patent number: 7183525Abstract: The invention relates to a roasting/grilling device with a roasting/grilling plate (7) and with a thermostatic regulation of the roasting/grilling power. For this the temperature of the roasting/grilling plate (7) is monitored in a contactless manner by way of electromagnetic radiation. In combination with an efficient regulation and control unit, suitably arranged heating elements, preferably induction coils (30), as well as with a special roasting/grilling plate surface, an optimal roasting/grilling of food to be roasted/grilled becomes possible, in particular due to the fact that the temperature drops which are otherwise common with roasting/grilling device are prevented.Type: GrantFiled: June 3, 2003Date of Patent: February 27, 2007Assignee: Inducs AGInventor: Christian Fuchs

Patent number: 6841764Abstract: A heat retention system for keeping meals warm by converting induced electromagnetic energy of arisen heat. The system contains a receptacle (5, 55, 103) with passive elements (3, 53) which, via a plate (9, 59, 209), are in active connection with active elements (2, 210). Sensors (16, 18, 56, 215) and an optimised control unit (212) regulate the temperature of the meals (8) located in the receptacle (5, 55, 103), so that these meals are not cooked and energy is supplied in a directed manner. Preferably, the heat retention system is configured as a heat retention device that has a modular construction and may be dismantled into individual modules (101, 102, 103, 104) and may be assembled of individual modules (101, 102, 103, 104). For this, the individual modules include fastening devices, (105-108, 126, 135, 138, 145-148, 155, 158), such as turnbuckles (155, 158) or positive-fit fastening means (105-108, 126, 135, 138, 145-148) that correspond to the fastening devices of further modules.Type: GrantFiled: March 8, 2002Date of Patent: January 11, 2005Assignee: Inducs AGInventor: Christian Fuchs
