Description

Technical Field

[0001] The utility model belongs to the technical field of cooking equipment and relates to a frying and grilling cooking equipment with multiple cooking cavities. Background Art

[0002] An air fryer is a machine that uses air to "fry," essentially replacing the hot oil in the frying pan with air to cook the food. This hot air also removes moisture from the food's surface, giving the food a similar fried texture. The air fryer uses "high-speed air circulation technology" to generate hot air by heating the heat pipe inside the machine. A fan then blows this hot air into the pot to heat the food, circulating the hot air within the enclosed space. The air then uses the food's own fat to fry the food, dehydrating it and leaving it golden and crispy, achieving the desired fried texture.

[0003] Existing air fryers all have a single cooking chamber, meaning they can only fry one type of food at a time. Mixing two foods together can cause flavor contamination, affecting the cooking effect. Furthermore, a single cooking chamber slows down cooking. To address this issue, frying and grilling devices with multiple cooking chambers are currently available. For example, Chinese Patent No. CN202311828898.7, titled "Frying and Grilling Device with Multiple Cooking Chambers," comprises a housing, a cooking liner, and a motor mount positioned between the housing and the cooking liner. Gaps are defined between the outer wall of the cooking liner and the motor mount, and between the outer wall of the cooking liner and the inner wall of the housing, forming a first cooling air duct surrounding the cooking liner and connecting to the accommodating chamber. A second cooling air duct is also provided between adjacent cooking liner compartments, connecting to the accommodating chamber. This cooking device, with its cooling air duct, effectively dissipates heat, preventing heat buildup and reducing the temperature of the air fryer's exterior, ensuring user safety. However, its complex structure, numerous components, poor heat utilization, and high energy consumption require further structural improvement. Summary of the Invention

The upper cover is a circular cover with an opening at the front end. The upper cover is arranged on the heat insulation plate and fixed by screws. An air inlet cover is buckled at the cold air inlet on the rear side of the motor bracket.

[0008] Furthermore, the air outlet is opened in the middle position of the rear wall of the cooking pot, the air guide channel is an arc-shaped curved pipe, and an interface connected to the air guide channel is provided on the outside of the air outlet.

[0009] Furthermore, the cover is fixed to the frame at the upper end of the cooking pot by screws, the air guide surface is located in the middle of the cover, convex upward and inclined backward, and a connecting part is provided at the rear end of the cover to cooperate with the front end of the upper cover of the motor bracket.

[0022] The specific structure is as follows: the shell 1 is assembled from a frame 11, left and right side panels 13, a rear cover 15, a top plate 12, and a bottom plate 14. In this embodiment, there are two cooking pots 3, which are arranged on the frame 11 one above the other. The motor bracket 21 is arranged horizontally on the frame 11 and is located at the upper rear end of the cooking pot 3. The upper end of the motor bracket 21 is provided with a heat insulation plate 25. The front end of the heat insulation plate 25 abuts against the upper end of the cooking pot 3 to form an air guide plate. A hot air outlet 3b is formed between the air guide plate and the front end opening of the upper cover 20. The heating element 23 and the fan blades 24 are arranged above the heat insulation plate 25. The upper cover 20 is a circular cover with an opening at the front end.
