A smart oven includes a box body unit, a heating unit and a feed unit. The box body unit includes a box body that has a first inner wall surface, two second inner wall surfaces, two third inner wall surfaces, and a heating chamber having a chamber opening that faces downward. The heating unit includes a plurality of upper radiation heating lamps disposed above the chamber opening, and a plurality of outer radiation heating lamps disposed in proximity to the second and third inner wall surfaces. The feed unit includes a carrier platform that is movable relative to the box body between a material-placing position and a material-operating position, in which the carrier platform is distal from and closes the chamber opening, respectively.
