Abstract

A microwave oven comprises: a housing defining an interior cavity; a magnetron positioned within the housing and external to the internal cavity; and a microwave antenna in electrical communication with the magnetron and positioned adjacent to a lower surface of the interior cavity. The microwave oven also includes a heating plate including a glass ceramic substrate defining at least a portion of the lower surface of the interior cavity. The heating plate further includes a resistive heating coating applied on a portion of the glass ceramic substrate, and the heating plate defines at least one unobstructed microwave transmission path from the microwave antenna to the interior cavity.

Description

Background technique [0001] The present disclosure relates generally to a microwave oven and, more particularly, to a microwave oven having a resistive heating plate along a portion of a lower interior cavity surface. [0002] Existing microwave ovens have incorporated an upper heating element (such as a quartz heating tube) with an adjacent reflective area for directing radiant heat from the heating element downwards towards the food in the cavity to provide baked / cooked or crispy cooking mode. However, it is understood that such a solution only radiates heat to one side of the food (ie the upper side), while the other side is only cooked by microwaves. Some other existing solutions add additional heating elements below the lower surface (which can be made of glass). However, in order to allow microwaves to penetrate effectively into the cavity, such heating elements must be positioned at the rear of the cavity, which prevents the lower heating elements from providing benef...
