Abstract
A heating appliance, such as a microwave oven, includes a housing having interior walls with interior surfaces defining a cooking chamber for heating food. The heating appliance also includes a camera positioned within the housing to capture images of food in the chamber, and a shield positioned between the camera and the food. The shield has a body with a first surface facing an area for receiving food within the chamber and a second opposite surface facing the camera. The shield includes a first transparent conductive metal coating on one or both of the first surface and the second surface, such that the shield dissipates heat and reflects microwave radiation to protect the camera.
