The central body (6) contains an external insulation metal layer (11) and inner facing layer (12) made of parallelepiped blocks (13), and each of them containing six longitudinal grooves (16), fabricated in the floor (14) and the ceiling (15) of the oven chamber (7) in which spiral-like heating elements (17) are fitted. A bottom layer (18) made of one layer of ceramic floor tiles (19) is fitted on the ceramic blocks (13) building the floor (14) of the baking oven chamber (7). (11) 140
