Abstract
A cooking appliance for grilling food products has a griddle plate and a heating assembly that contains a non-contact infrared heating element to achieve uniform plate temperatures, fast initial warming times and fast recovery times. The heating element is situated in a cavity formed by thermal insulating material in the assembly. When the assembly is secured to the griddle plate, there is a space between the heater element and the griddle plate to allow infrared radiation heat transfer to heat the griddle plate. The insulating material has a relatively high insulating factor so as to minimize heat loss and reduce energy usage.
