Abstract:
An apparatus for detecting movement of a vessel positioned on a cooktop surface, the apparatus comprising:a radiant heating element positioned below the cooktop surface for heating at least the vessel; a controller connected to the radiant heating element for controlling energy supplied to the radiant heating element; at least one sensor connected to the controller wherein the at least one sensor providing information to the controller for determination of at least a sensed vessel heating condition; an inductive loop positioned proximate to the cooktop surface; and a detection circuit connected to the controller and the inductive loop for detecting movement of the vessel on the cooktop surface using signals produced by at least the inductive loop, wherein the controller prevents the sensed vessel heating condition from being detected when the power to the radiant heating element increases after movement of the vessel has been detected by the detection circuit from the inductive loop.
