Patent number: 8492684Abstract: A method for detecting the presence of a cooking vessel on an induction heating element is disclosed. The induction element is placed below a glass surface and a conductive electrode placed below the glass surface to detect if a cooking utensil is placed on the induction heating element. The electrode measures capacitance, which indicates to the user whether the cooking utensil is present on one or more induction heating elements. After activation by a user, a second detection of the cooking utensil is accomplished by feeding power to the induction heating element and by assessing at least an electrical parameter of a power circuit thereof.Type: GrantFiled: October 20, 2009Date of Patent: July 23, 2013Assignee: Whirlpool CorporationInventors: Diego Neftali Gutierrez, Ettore Arione
