The invention relates to a cooking appliance (1) having a housing (2) and having a muffle (3) which is arranged in the housing (1) and which delimits, with walls (5, 6, 7, 8, 9), a cooking chamber (4) of the cooking appliance (1); and having a hot air
system (12) which has a front wall (13) which is arranged in the cooking chamber (4) such that, between a rear wall (7) of the muffle (3) and this front wall (13), an
accommodation space (14) for components (15, 16) of the hot air
system (12) is formed, wherein the front wall (13) has air through-openings (17, 20) through which hot air can be conducted from the
accommodation space (14) into the cooking chamber (4); and having a plate-like cooking chamber partition (21) which can be removed from the cooking chamber (4) and which, in its end position in the cooking chamber (4), divides the cooking chamber (4) into a first cooking chamber region (4a) and a second cooking chamber region (4b), wherein, viewed in the
depth direction (z) of the cooking appliance (1), the cooking chamber partition (21) is arranged overlappingly with the front wall (13) in its end position, and / or, viewed in the height direction (y) of the cooking appliance (1), the cooking chamber partition (21) is arranged overlappingly with the front wall (13) in its end position, and an uneven flow guide structure (24) is configured on a side (22) of the cooking chamber partition (21) facing the front wall (13) in an
edge region (23) of the cooking chamber partition (21) which adjoins the front wall (13), by means of which flow guide structure hot air (L) which enters into the cooking chamber (4) through the air through-openings (17, 20) and flows onto the cooking chamber partition (21) can be deflected towards the cooking chamber region (4a) which is to be supplied with hot air (L).
