A household cooking oven (1) comprises a bearing structure (2), a muffle (5) and a front door (4) to close frontally the muffle (5), in the muffle (5) there being present a bulkhead (10) generally facing a rear muffle wall (5a), the bulkhead (10) dividing the inside of the muffle (5) in a front cooking chamber, that extends between the door (4) and the bulkhead (10), and a rear air-distribution chamber, that extends between the bulkhead (10) and the rear muffle wall (5a). In the air-distribution chamber there are operatively arranged at least one heating resistance (11) and an impeller (12) of a centrifugal fan (12, 13). The air-distribution chamber has an outlet section (15, 22) for delivery of air to the coking chamber and an inlet section (20-23) for intake of air from the cooking chamber, the outlet section (15, 22) comprising passageways (22) in generally peripheral positions of the air-distribution chamber. According to the invention, the inlet section comprises an air-suction cavity or chamber (20) defined in the bulkhead (10), the air-suction cavity (20) having at least one inlet (23), defined in a front (10b) of the bulkhead (10) and oriented towards the cooking chamber, and at least one outlet (21), defined in a back of the (10a) of the bulkhead (10) and oriented towards the impeller (12) of the fan. |
