Oven camera assembly with heat management structures

An oven, comprising:

• a liner defining a cooking cavity having an open side, a back wall opposite the open side, and a top wall extending between the open side and the back wall, the top wall having a camera opening defined therethrough in a position more proximate to the back wall than the open side;
• and
• a camera assembly mounted on the top wall of the liner outside the cooking cavity and including:
• an insulating block contacting the top wall of the liner and defining an aperture therethrough, a lower side of the aperture being aligned with the camera opening in the top wall of the liner;
• a camera mounted over the insulating block and having a lens and a field of view centered around an axis and extending away therefrom in a direction away from the lens of the camera along the axis to define a viewing angle directed through the aperture in the insulating block and through the camera opening in the top wall of the liner;
• and
• a glass substrate coupled within the lower side of the aperture to enclose an air gap within the aperture between the glass substrate and a housing of the camera;
• wherein the aperture in the insulating block tapers outwardly from an upper side of the aperture to the lower side of the aperture at an opening angle approximately equal to the viewing angle of the camera.

A camera assembly, comprising:

• an insulating block for mounting against and in contact with a surface and aligned with an opening through the surface, the insulating block defining an aperture therethrough, a lower side of the aperture being aligned with the opening in the surface;
• a sink washer having a hole therethrough aligned with a top side of the aperture through the insulating block, the sink washer mounted to the insulating block in partial contact therewith and extending outward from the top side of the aperture, the sink washer including:
• a major surface extending outwardly around the opening and a flange surrounding the opening and extending away from the major surface, the flange contacting the insulating block and spacing the major surface away therefrom;
• a first fin and a second fin extending from the major surface in a direction away from the insulating block and opposite the flange, the sink washer;
• and
• a first base and a second base spaced from the flange and extending away from the major surface to contact the insulating block and receive mounting screws to retain the sink washer with the insulating block with the major surface spaced away therefrom;
• a camera mounted to the sink washer and having a lens, the camera further having a field of view centered around an axis and extending away therefrom in a direction away from the lens of the camera along the axis to define a viewing angle directed through the aperture in the insulating block and through the opening in the surface, the sink washer directing heat away from the camera and away from the surface, the camera further having a body positioned between the first fin and the second fin;
• and
• a glass substrate coupled within the lower side of the aperture to enclose an air gap within the aperture between the glass substrate and a housing of the camera.
