摘要： Method to control a quasi-resonant inverter (13) in an induction cooking appliance (1) provided with induction heating coil (4). The quasi-resonant inverter (13) comprises a switching device (21) electrically connected to the induction heating coil (4) by a node (20) having a first voltage (VC(t)) which is indicative of the voltage across the power switching device (21). The method comprising the steps of: providing to the switching device (21) an enabling signal (K1) comprising a plurality of pulses, in order to switch-on and switch-off said switching device (21) for a switch-on period (tON) and a switch-off period (tOFF), determining a second voltage (VCmin) indicative of the minimum value of the first voltage (VC(t)) during the switch- off period (tOFF), regulating the switch-off period (tOFF) based on the second voltage (VCmin), and regulating the enabling signal (K1) based on the regulated switch-off period (tOFF).

摘要： A method for performing a treatment by a domestic appliance having a programmable control unit and a graphic display. The method includes executing a program for performing the treatment, encoding information about the appliance, the program and/or a current status of the appliance, generating a two-dimensional code representing the encoded information, and displaying the code on the graphic display, so that the code is detectable by a camera or scanner of a mobile computer device. Further, a method for processing information about a treatment performed by a domestic appliance, wherein the information is encoded by a two-dimensional code on a graphic display of the appliance. The method includes detecting the two-dimensional code by a camera or scanner, decoding the code, and indicating the decoded information on a display, and/or transmitting the decoded information to a computer device via the internet, and/or processing the decoded information by an application software.
