[0020] Reference Figures 1 to 4A hot air guide structure for an air fryer includes a hot air device and a cooking cavity disposed within a fryer body 1, and a fryer body that is housed within the cooking cavity. A hot air cavity 3 accommodating the hot air device is disposed at the back of the cooking cavity. The hot air cavity 3 and the cooking cavity are separated by a back panel 4. The back panel 4 is provided with an air blowing port 41 and an air return port 42. A first vent 61 and a second vent 62 are provided on the sidewalls of the fryer body. The second vent 62 is located on the back sidewall of the fryer body and interfaces with the air return port 42. When the hot air device is in operation, hot air is blown from the air blowing port 41 into the cooking cavity. The hot air then flows through the first vent 61 into the fryer body, then returns to the hot air cavity 3 through the second vent 62 and the air return port 42. The hot air device then actuates the hot air to be blown out again from the air blowing port 41, forming a circulating hot air duct. The top wall of the cooking cavity is formed with an air guide structure, and the air blown out of the air outlet 41 is guided downward by the air guide structure to enter the fryer body through the top opening and join the above-mentioned circulating hot air duct, thereby increasing the source of hot air and further heating the food in the fryer body, thereby achieving more comprehensive and uniform heating of the food.

[0021] The air guide structure can be a concave air guide cavity 23 recessed in the top wall of the cooking cavity, or a protruding air guide platform (not shown in the figure) protruding from the top wall of the cooking cavity. The ultimate purpose of both structures is to form a downward air guide wall to allow hot air to be turned downward and enter the interior of the fryer body through the opening of the fryer body.

[0022] As a preferred embodiment of the present invention, the air guide structure is a concave air guide cavity 23 extending from the back panel 4 to above the top opening of the fryer body. After entering the concave air guide cavity 23, its side walls guide the hot air downward through the top opening and into the fryer body. Preferably, the portion of the concave air guide cavity 23 near the back panel 4 is wider than the portion farther from the back panel. That is, the concave air guide cavity 23 is arranged in a "convex" shape on the cooking chamber top wall. The wider portion receives more hot air, which is then concentrated into the fryer body at the narrower portion, guided by the walls of the concave air guide cavity 23. The concave air guide cavity 23 can have various shapes, requiring only a wide back and narrow front, such as a trapezoidal shape. Furthermore, the side walls of the concave air guide cavity 23 are arc-shaped, allowing the hot air entering the concave air guide cavity 23 to be guided more smoothly downward through the fryer body opening and into the fryer body, thereby reducing wind noise.

[0023] In addition, when the air guide structure is an air guide baffle, the air guide baffle can be a plate-shaped component (not shown in the figure) installed on the top wall of the cooking cavity, which is simple and convenient to arrange.

[0024] Preferably, the air blowing port 41 includes a first air blowing port 411 and a second air blowing port 412. The first air blowing port 411 is composed of a plurality of through slots arranged on the surface of the back plate 4 surrounding the return air port 42. The air blown out by the first air blowing port 411 is mainly blown toward the periphery of the fryer body and enters the interior of the fryer body from the first vent 61. The second air blowing port 412 is formed by the gap between the back plate 4 and the top wall of the cooking cavity. The air guide cavity 23 is connected to the second air blowing port 412. The second air blowing port 412 is specifically used to provide hot air to the air guide cavity 23, so that the air guide cavity 23 can guide more hot air into the fryer body for more comprehensive heating and frying.

[0025] The hot air guide structure of the present invention can be applied to a double-layer air fryer, which includes a fryer body 1, an upper cooking cavity 21 and a lower cooking cavity 22 arranged in the fryer body 1. The lower cooking cavity 22 adopts a back hot air device solution, including a lower hot air device 72 and a lower fryer body 6 inserted therein, and adopts the hot air guide structure of the present invention; while the upper cooking cavity 21 adopts a conventional top hot air device solution, including an upper hot air device 71 located at the top and an upper fryer body 5 inserted therein and located below the upper hot air device 71.
