A door with a gas burner on an inner surface and a system for carrying a combustible gas to the burner on the outer surface thereof. The door comprises a pair of metal sheets rigidly connected to one another at the edges thereof, each sheet having input and output openings for the gas mixture that are mutually separated in order to leave an inner space receiving a deflector plate serving as a thermal shield to be swept over on either side by the flow of the gas mixture supplying the burner. This arrangement reduces heat loss through the door; thus, keeping the outer surface cold, avoiding the risk of burns, and preheating the gas mixture. The invention can be used in heating appliances.

An oven and a door assembly are provided. The oven includes a casing, a cooking chamber located inside the casing and having a shape with an open front, and a door assembly having an inner space therein and configured to close and open the open front of the cooking chamber. The door assembly includes a handle member, a shielding member located between the inner plate and a rear side of the door assembly and configured to shield an air flow, an inlet formed in a bottom of the door assembly and configured to allow an inflow of air from outside of the door into the inner space, and an outlet located on top of the door assembly at the rear of the handle member and configured to provide a space to allow air to move outside the door assembly.
