US Patent 11747087 Household appliance including reflective door

Household appliances may include partially reflective (e.g., one-way mirror) glass as part of an oven door. The partially reflective glass may transmit light from an interior of the household appliance and may reflect light from outside the household appliance. Accordingly, one can see into the lighted interior but a camera inside the interior cannot see out through the door. In some examples, the household appliance includes a lamp and a camera disposed within the cavity of the appliance. The lamp and the camera are interlocked to protect user privacy by activating the one-way feature of the door glass as needed.
