INDUCTION COOKING APPLIANCE, WIRELESS KITCHEN APPLIANCE AND WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to an induction cooking appliance (1) comprising an induction coil (2) for producing a time-varying electromagnetic field for inductively powering a wireless kitchen appliance (3) and a control unit (5) for generating and supplying a driving signal to the induction coil (2). In the induction cooking appliance (1) according to the present invention, the control unit (5) has a normal mode for inductively powering the wireless kitchen appliance (3) and a communication mode for transferring information to the wireless kitchen appliance (3) via said induction coil (2), by using an encoding scheme for encoding the driving signal in accordance with transferred information, while inductively powering the wireless kitchen appliance (3). The present invention also relates to a wireless kitchen appliance (3) comprising a receiver induction coil (6) configured to sense a time-varying electromagnetic field produced by the induction cooking appliance (1).
