HOUSEHOLD COOKING APPLIANCE

摘要

A household cooking appliance, in particular an oven, comprises a cooking chamber (6) defined by a muffle (5) having a fume outlet (7) at an upper wall (5a) of the muffle (5), and a front door (4), for opening and closing the cooking chamber (6). The appliance further comprises: a delivery channel (30), defined by a duct body (10) that extends above the upper wall (5a) of the muffle (5), the duct body (10) having an outlet (30a) of the delivery channel (30) that is substantially at a front region of the appliance, above an upper portion of the door (4), at least one air intake (23a, 31a) in fluid communication with the delivery channel (30), a fume inlet (10d) in a lower wall (10a) of the duct body (10), which is in fluid communication with the fume outlet (7) of the muffle (5) and with the delivery channel (30); a ventilation assembly (20), operatively associated to the duct body (10), to draw in air from the air intake (23a, 31a) and fumes from the fume outlet (7) of the muffle (5) and expel a resulting air/fumes mixture from the outlet (30a) of the delivery channel (30), the ventilation assembly (20) being in a rear end region of the duct body (10) that is generally opposite to the outlet (30a) of the delivery channel (30). The at least one air intake (23a, 31a) comprises at least one passage (23a) at an upper wall of the duct body (10) and the ventilation assembly (20) comprises a radial fan (21) with a centrifugal impeller (22) thereof within the duct body (10). The centrifugal impeller (22) has an upper impeller section and a lower impeller section, prearranged for drawing in air from said at least one passage (10c, 23a) and fumes from the fume outlet (7) of the muffle (5), respectively, the lower section of the centrifugal impeller (22) being positioned above the fume inlet (10d) of the duct body (10) substantially coaxial thereto and to the fume outlet (7) of the muffle (5), in such a way that at least the fumes are drawn in from the fume outlet (7) substantially in the direction of the axis (X) of the impeller (22) and forced in a radial direction into the delivery channel (30) for being expelled from the corresponding outlet (30a).
