OVEN BASED ON A COMBINATION OF HEATED AIR AND INFRARED HEATING ELEMENT

摘要

A cooking oven comprising a housing, a cavity, an oven door, an air plenum, an infrared heating element, and a thermal insulating layer placed between the infrared heating element and the air plenum is disclosed. The infrared hearing element comprises a wire-like heating element shaped in a serpentine-pattern to form a plurality of fingers. The thermal insulating layer comprises a plurality of air channels interconnecting the air plenum and the cavity, and one or more temperature decoupling chambers for thermally insulating the air plenum from the infrared heating element. The air channels are positioned interleavingly between the plurality of fingers so that airstreams coming from the air plenum through each of the air channels into the cavity do not substantially contact and convectively cool the infrared heating element. The temperature decoupling chambers may use air as a thermal insulator.
