Abstract: A cooking appliance includes an appliance cover, appliance body and inner lid, the appliance cover arranged above the appliance body in a closable and openable manner, the appliance body having a heating structure. The appliance cover includes a cover body that includes a venting passage providing communication between the cooking appliance and the outside, the inner lid detachably mounted to the cover body; a baking assembly arranged below the cover body, the inner lid located below the baking assembly when mounted to the cover body; a venting cap detachably mounted at any one end of the two ends of the venting passage, wherein the venting cap is assembled at a bottom end of the venting passage when the inner lid is dismounted, and the venting cap is assembled at a top end of the venting passage after the inner lid is mounted.

Abstract: A cooking appliance comprises a lid (1), an appliance body and an inner cap (3), the lid (1) being arranged on the appliance body in a manner capable of opening and closing the appliance body, the appliance body comprising a heating structure, and the lid (1) comprising: a lid body (4); a baking assembly (5) arranged below the lid body (4), the lid body (4) being provided with a venting passage (6) through which the inside of the cooking appliance communicates with the exterior, the inner cap (3) being detachably mounted to the lid body (4) and located below the baking assembly (5), a lateral wall of the venting passage (6) being provided with a venting hole; a blocking member (27) slidably arranged in the venting passage (6), the blocking member (27) sliding downwards to a bottom of the venting passage (6) when the inner cap (3) is detached, and the blocking member (27) blocking the venting hole when the blocking member (27) is located at a top or a bottom of the venting passage (6).
