The present invention relates to kitchen cooking appliance and in particular to a multiduty cooking appliance.
There are a wide variety of kitchen cooking appliances, such as pressure cookers, induction cookers, steamers, electric cookers and air fryers. The existing kitchen cooking appliances have their own characteristics and can only be used alone.
At present, multiduty air fryers have also been developed. For example, a Chinese Invention Patent CN114287810A, entitled MULTIPURPOSE AIR FRYER, disclosed such an air fryer which comprises a fryer body in which a first heating chamber, a heat radiating chamber and a second heating chamber are arranged, wherein the first heating chamber, the heat radiating chamber and the second heating chamber are sequentially distributed in the height direction of the fryer body; a first heating component and a first impeller are arranged at the bottom end of the first heating chamber, and the bottom wall of the first heating chamber is formed as a heating portion; the first impeller is used to guide heat to the heating portion during rotation; a second heating component and a second impeller are arranged in the second heating chamber, and the second heating component is used to heat air in the second heating chamber; the second impeller is rotatably mounted in the second heating chamber; an air inlet hole is formed on the sidewall of the heat radiating chamber; a driving member and a heat radiating fan are arranged in the heat radiating chamber; and, the driving member is used to drive the heat radiating fan, the first impeller and the second impeller to rotate. The air fryer can realize multiple purposes, such as baking, steaming or frying.
Although the air fryer has multiple functions, the first heating chamber, the heat radiating chamber and the second heating chamber are integrated and cannot be used independently, so that the range of applicability of the product is limited, and the whole product is large, heavy and inconvenient to store and carry. Moreover, the heating position in the upper portion of the product is high, that is, the cooking position is high, so the usage is inconvenient for users.
Therefore, the technical problem to be solved by those skilled in the art is to design a flip-open air fryer with simpler and more reasonable structure and steaming function.
