Appliance for cooking by air flow

Appliance for cooking and/or reheating food, comprising:

• A housing with a cooking vessel arranged to receive the food to be cooked and/or reheated,
• A circuit for heating by air flow, comprising an air duct arranged to channel and direct a stream of hot air onto the food to be cooked and/or reheated,
• wherein the air duct has at least one cross-section downstream of which the turbulence from the air flow is reduced by limiting one geometric dimension of the stream of air channeled by said cross-section of the air duct,
• wherein the air duct has an elbow and at least two heating means, each heating means comprising a support forming a fin in which the supports are arranged with a predefined orientation with respect to the flow of air, to direct the air stream in the direction of the elbow,
• wherein the supports of the fins are arranged at an angle in a direction of an upstream portion of the elbow to change a direction of a vertical air flow into the elbow,
• wherein an entire portion of each fin is arranged at an angle in the at least one cross-section in a direction of the upstream portion of the elbow such that the fins face one another to separate the air stream into at least three veins of air, each with a thickness reducing a turbulence of the flow of the air stream inside the air duct,
• wherein the air duct comprises one upstream end, having at a predetermined distance from the upstream end, a gradually reduced cross-section arranged to progressively limit said geometric dimension of the air stream channeled along one portion of the air duct, and
• wherein the gradually reduced cross-section begins upstream of the elbow and ends at the elbow.
