An inductive cooktop includes: at least one cooking zone; at least one heating coil associated with the cooking zone; and a cooktop controller for driving the at least one heating coil in an operating mode of the inductive cooktop to heat a cooktop utensil with a transmitter unit, which cooktop utensil is placed on the cooking zone. The inductive cooktop is operable in a standby mode in which driving of the at least one heating coil is disabled. The inductive cooktop is operable in a ready mode. The inductive cooktop is switchable from the standby mode to the ready mode by a wake-up signal received by a receiver unit of the cooktop controller. In the ready mode, the at least one heating coil is drivable by the cooktop controller such that, on one hand, the cooktop utensil is prevented from being effectively heated for a preparation operation.

For heating a mold efficiently and uniformly and for protecting an induction coil from corrosive gases, an upper plate that contacts an upper end face of a mold, and a lower plate that contacts a lower end face of the mold are provided, and an induction coil, provided to each plate, has a voltage applied by a commercial power supply. Each plate has a metal plate body in which a recessed housing portion that houses the induction coil is formed, and a cover that closes the recessed housing portion in a state where the induction coil is housed therein. A cover placement portion having a step that is greater than or equal to the thickness of the metal cover is formed in the metal plate body, and a plurality of jacket chambers in which a gas-liquid two phase heating medium is enclosed are formed in the metal plate body.

The present disclosure relates to an aerosol generating device for heating solid tobacco substance. The aerosol generating device includes a housing having a first air inlet, a power supply, a cup body arranged in the housing, a coil module, and a heating element. The power supply is configured for supplying an alternating current power supply. The cup body is configured for receiving the solid tobacco substance, and defines a second air inlet. The coil module is arranged between the housing and the cup body. Two opposite ends of the coil module are connected to the alternating current power supply, such that the coil module generates a high frequency alternating magnetic field. The heating element is arranged at a center of the cup body. The heating element is configured for generating an eddy current and heat in response to the alternating magnetic field, thus heating the solid tobacco substance.
