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 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 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 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 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 <EOS>
