Abstract

A kitchen oven comprising: a cooking compartment (2), a ventilation compartment (10) behind said cooking compartment (2); a cover (7) separating the cooking compartment (2) and the ventilation compartment (10); at least one electrical resistor (12) arranged within said ventilation compartment (10); at least two fans (11a; 11b) arranged within said ventilation compartment (10) and designed to simultaneously move with opposite circular motions, thereby generating a fluid circulation inside the ventilation compartment (10) between inlet openings, which are in front of said fans (11a; 11b), and outlet openings, which are radially offset from said fans (11a; 11b); wherein the ventilation compartment (10) is a single volume and the total surface of the outlet openings is smaller than the total surface of the inlet openings.
