Abstract: The invention concerns a toaster comprising a frame arranged in a casing, at least a vertical grill chamber open at the top part of the casing, a peripheral roof at the opening of the grill chamber and integral with the toaster, having a top edge provided with openings for receiving rolls, heating elements located in the proximity of the grill chamber. The invention is characterized in that at least part of the edge of the rood is raised relative to the top part of the casing. Said integrated device for heating bread is associated with specially shaped grills for holding rolls, said grills comprising atop edge substantially perpendicular to said grills and oriented outwards of the chamber, so as to partially close the heating chamber, when they are brought closer to each other, thereby deflecting the ascending hot air flow generated by the heating elements.
