Abstract: The invention relates to a method for calibrating a power control loop of an induction hob (1), the induction hob (1) comprising a power stage (10) including at least one induction element (21), a measurement unit (12) and a control unit (11), the method comprising the steps of: —coupling the at least one induction element (21) with a reference load; —powering the power stage (10) at predefined working conditions by means of said control unit (11); —deriving a measurement value being indicative for the power transferred from the power stage (10) to the reference load by means of said measurement unit (12); —providing the measurement value to the control unit (11); —calculating a correction value based on the measurement value and a reference value; —storing the correction value in a storage entity in order to modify measurement values provided by the measurement unit (12) based on the correction value when operating the induction hob (1).

Abstract: An induction heating arrangement (1000) including four coils of a smaller diameter (1100, . . . , 1400) and a coil having a larger diameter (1500) is provided. The coils are arranged on a first plane (2100) and on a second plane (2200). In order to adapt a cooking area (1600) to the size of a pot, either the larger coil (1500) or one or more of the smaller coils (1100, 1400) are operated. A power supply circuitry (2400) is shared between the coils of the two planes. A selector (2300) disconnects a respective coil of the plane of coils that is not operated in order to avoid coupling, interference and loss of energy. Guiding elements of the magnetic flux (1110, 1115, 1540) confine the magnetic field in the area of the pot. A method of operating the induction heating arrangement is also provided.

Abstract: A gas-supply connection assembly, a method of connecting a gas supply line to a gas inlet port, and a gas cooking appliance. In particular, a gas-supply connection assembly for gas-tightly connecting a gas supply line to a gas inlet port of a gas consumer is provided, in which the gas supply line is inserted into the gas inlet port and connected thereto in that a bulge section effectuated at an outer circumference of the supply line in the inserted condition by plastic deformation thereof gas-tightly engages in a form-fit locking manner into a given indentation in an inner bushing of the gas inlet port.

Abstract: An actuation system for automatic actuation of at least one element covering an opening of a household appliance. The actuation system includes at least one actuation element constituted by at least one shape memory alloy element. The actuation system is adapted to actuate the element when applying heat to the actuation element.

Abstract: The gas heating arrangement (1000, . . . , 4000) according to the present invention improves the heat transfer of a Kitchen hob that has moveable gas burners (1180, 2140, 2160). Either a support structure (1180) is moved along with the gas burner or the support structure has a curved shape (3400) according to the movement trajectory (6500) of a gas burner, while at the same time leaving the space of the gas burner where the flames emanate free in order to allow optimum heat transfer at any location of the moveable gas burner. The method according to the invention provides a pin device and a hole at a turntable (5100, 6250) in order to apply movement to the turntable while not having to touch hot elements.
