Publication number: 20230389137Abstract: A cooktop appliance apparatus for use in cooking includes a controller for controlling operation of the fan system based on an average power level supplied to a heating system, and based on a temperature measure associated with one or more subsystems. The appliance includes a hardware-implemented safety module having two or more temperature actuated safety circuits. The appliance includes a user interface adapted to receive a user input with respect to operating parameters of the heating system, the user input including a heating control mode and a set temperature. The appliance includes a controller adapted to identify a cooking vessel on an induction cooktop.Type: ApplicationFiled: July 7, 2023Publication date: November 30, 2023Applicant: BREVILLE PTY LIMITEDInventors: LICHAN MENG, MARIAN SILVIU ROSIAN, RICHARD HOARE, BRENDAN JOHN FOXLEE, VYVYAN ROSE, DAVID DAVENPORT, TIBOR HEGEDIS

Patent number: 11190015Abstract: An apparatus for controlling one or more switched high power loads (or heating elements). The apparatus including: one or more switched high power loads (or heating elements), each high power load being powered from a common alternating current power source, and wherein each load is independently switched using a switching signal for zero crossing switching to achieve a desired average power output; the switching signal is generated that comprises a repeated switching sequence; the switching sequence indicates a respective selecting activation for each of the switched high power load over a sequence of half or full cycles.Type: GrantFiled: March 29, 2016Date of Patent: November 30, 2021Assignee: BREVILLE PTY LIMITEDInventors: Ashley Marsh-Croft, Tibor Hegedis, Brendan John Foxlee, Emma Craig, Lichan Meng
