The present invention relates to a domestic appliance, in particular domestic oven, comprising: —a treatment chamber; —at least one inner panel (6) and one outer panel (1) for allowing insight into the interior of the treatment chamber from the exterior; —at least one optical monitoring device (4) for optically monitoring at least a part of the interior of the treatment chamber through the inner panel (6) and the outer panel (1); —at least one optical shade element (2) for at least partially preventing irritating light from reaching an optical sensor of the optical monitoring device (4); characterized in that the optical monitoring device (4) is arranged on a side of the outer panel (1) opposite to the treatment chamber side of the outer panel (1) and in a distance to the outer panel (1), and wherein the optical shade element (2) is arranged in an intermediate space between inner panel and outer panel (1) and circumferentially encloses at least partially the optical path (9) of the optical monitoring device (4) extending from the interior of the treatment chamber to the sensor of the optical monitoring device (4) through the inner panel, the outer panel (1) and the intermediate space between inner panel and outer panel (1).
Domestic oven, comprising:
A cooking oven comprising a treatment chamber for cooking food, a door configured to selectively open and close said treatment chamber, said door comprising a transparent, un-tinted inner panel and a transparent, un-tinted outer panel separated from one another and defining a space therebetween, a sensor disposed adjacent to said outer panel on a side thereof opposite the treatment chamber, said sensor being adapted to capture an image of a food stuff when being cooked inside the treatment chamber via an optical path inclined at an angle α in an imaginary vertical plane, said optical path extending through said first panel and said second panel, a funnel-shaped opaque optical shade extending between the first and second panels within said space and defining a funnel-shaped aperture that surrounds the optical path in said space, said funnel-shaped aperture converging from a first opening thereof adjacent said inner panel to a second opening thereof adjacent said outer panel so as to define an aperture angle u of said funnels-shaped aperture in said imaginary vertical plane, wherein said aperture angle u corresponds to said angle α, said optical shade being effective to inhibit light emitted from an external source and entering said space through said outer panel from being reflected or scatted within said space.
