Patent number: 10356853Abstract: An induction cooking system. The induction cooking system includes a base, one or more side walls, an induction coil, and an infrared temperature sensor. The base includes a base surface associated therewith. The base surface includes a window. The window is disposed within the base surface. The one or more side walls define a well above the base surface. The well is configured to receive a vessel disposed above the base surface. The induction coil is disposed within the base. The induction coil defines a first surface that is disposed below the base surface. The induction coil also defines a second surface that is disposed opposite from the first surface. The induction coil further defines an aperture disposed adjacent to the window and extending from a first surface toward a second surface of the induction coil. The infrared temperature sensor is disposed adjacent to the window and within the aperture.Type: GrantFiled: August 29, 2016Date of Patent: July 16, 2019Assignee: COOKTEK INDUCTION SYSTEMS, LLCInventor: Reinhard Metz
