An oven for cooking food comprising a cooking compartment and a door providing access to the cooking compartment, the door being able to move between a first position in which it allows access to the cooking compartment and a second position in which it prevents access to the cooking compartment, the door comprising: - a first plate; - a second plate which is substantially parallel with the first plate; - a frame connected to the first plate, at least partly interposed between the first and second plates (31, 32) and comprising retaining means for the second plate; - a locking profile for the second plate which is in contact with the second plate and which, operating in conjunction with the retaining means, allows positioning of the second plate; - means for connecting the profile to the frame; - a hollow space for the passage of a fluid, the hollow space being at least partly interposed between the first and second plates (31, 32) and extending between a fluid inlet section into the door and a fluid outlet section from the door, the inlet section being above the second plate with reference to the door in the second position; wherein the second plate with the door in the second position at least partly faces the cooking compartment, the first plate facing towards the outside of the oven; there being a first imaginary plane passing through and integral and parallel with the first plate and a second imaginary plane passing through and integral and parallel with the second plate; characterized in that said locking profile: - has a main direction of extension; - following the main direction of extension it extends along a stretch of a perimetric edge of the door, said stretch of the lateral edge, at least with the door in the second position, being the lower edge of the door; and in that the locking profile comprises a first deflector positioned at the fluid outlet section from the door for giving the fluid a trajectory comprising a motion component directed from the second plane towards the first plane. - a first plate; - a second plate which is substantially parallel with the first plate; - a frame connected to the first plate, at least partly interposed between the first and second plates (31, 32) and comprising retaining means for the second plate; - a locking profile for the second plate which is in contact with the second plate and which, operating in conjunction with the retaining means, allows positioning of the second plate; - means for connecting the profile to the frame; - a hollow space for the passage of a fluid, the hollow space being at least partly interposed between the first and second plates (31, 32) and extending between a fluid inlet section into the door and a fluid outlet section from the door, the inlet section being above the second plate with reference to the door in the second position; wherein the second plate with the door in the second position at least partly faces the cooking compartment, the first plate facing towards the outside of the oven; there being a first imaginary plane passing through and integral and parallel with the first plate and a second imaginary plane passing through and integral and parallel with the second plate; - has a main direction of extension; - following the main direction of extension it extends along a stretch of a perimetric edge of the door, said stretch of the lateral edge, at least with the door in the second position, being the lower edge of the door; and in that
