[0050] In some embodiments of this application, an air fryer is provided. Figure 1 This is a structural diagram of an air fryer. Figure 2 This is an exploded view of an air fryer.

[0051] The air fryer includes an organic assembly 100. The organic assembly 100 includes an organic body 110. A working cavity is formed inside the organic body 110, and a fan and a heating element 130 are provided on the organic body 110.

[0052] Specifically, the body 110 includes a bottom shell 111 and an upper shell 112. The upper and front sides of the bottom shell 111 are open, and the upper shell 112 is fixedly installed on the upper part of the bottom shell 111, covering the upper opening of the bottom shell 111. The bottom shell 111 and the upper shell 112 form a working cavity.

[0053] The fan and heating element 130 are fixedly installed inside the upper shell 112. When the air fryer is working, the fan and heating element 130 are activated, and the outside air flows through the heating element 130 under the action of the fan, blowing the heat generated by the heating element 130 into the working chamber.

[0054] The air fryer also includes an inner pot assembly 200. Figure 3 This is a structural diagram of the inner pot assembly 200. Figure 5This is a cross-sectional view of the inner pot assembly 200. The inner pot assembly 200 includes an inner pot 210, which forms a cooking cavity 211. A fan blows heat generated by the heating element 130 into the cooking cavity 211, and a base 230 and an air duct 220 are disposed inside the cooking cavity 211. Figure 4 This is a structural diagram of the inner pot assembly 200 after omitting the air guide 220. Figure 7 This is a structural diagram of the air duct 220. Figure 8 This is a structural diagram of chassis 230.

[0055] The chassis 230 divides the cooking cavity 211 into an upper space 212 and a lower space 213, which are arranged vertically along the height of the cooking cavity 211. The upper space 212 serves as the cooking space, and the lower space 213 serves as the hot air circulation space. The chassis 230 is provided with a plurality of first ventilation holes 231, which connect the upper space 212 and the lower space 213.

[0056] The air duct 220 is located within the upper space 212 and extends along the height of the cooking cavity 211. The air duct 220 draws hot air from the upper space 212 to the lower space 213. Multiple second ventilation holes 221 are provided on the wall of the air duct 220, connecting the upper space 212 to the inner cavity of the air duct 220.

[0057] During cooking, the food to be cooked is placed on the base plate 230, with the food located within the upper space 212 and surrounding the air duct 220. The fan and heating element 130 are activated, and external cold air flows from top to bottom through the heating element 130 under the action of the fan, exchanging heat with the heating element 130 to become hot air. The hot air flows downwards into the upper space 212, where the food at the top directly contacts the hot air, achieving baking. A portion of the hot air flows through the inner cavity of the air duct 220 into the lower space 213, where it then flows upwards through the first ventilation hole 231, baking the food at the bottom. Another portion of the hot air flows through the second ventilation hole 221 into the food on the side of the air duct 220, baking the interior of the food. In this way, the upper, lower, and middle parts of the food can all be heated and baked, improving the evenness of baking.

[0058] The air fryer of this application, by configuring a base 230 and an air duct 220, can direct a portion of hot air to the bottom of the food to heat and bake the food at the bottom, and can also direct another portion of hot air to the middle of the food to heat and bake the food in the middle, thereby achieving uniform baking of the food and improving baking efficiency.

[0059] In some embodiments of this application, the height of the upper space 212 is greater than the height of the lower space 213, so as to ensure that the upper space 212 serves as the volume of the cooking space as much as possible, thereby increasing the capacity of food that can be baked.

[0060] In some embodiments of this application, the air duct 220 is disposed in the middle of the upper space 212. The air duct 220 is disposed near the center so that when food is placed around the air duct 220, the hot air blown out from the second ventilation hole 221 of the air duct 220 can evenly heat and bake the interior of the food.

[0061] In some embodiments of this application, the chassis 230 is provided with an installation port 232, and the lower end of the air guide duct 220 is connected to the installation port 232 to realize the fixed installation of the air guide duct 220 in the upper space 212.

[0062] The chassis 230 serves as the mounting carrier for the air duct 220, eliminating the need for the inner pot 210 to be equipped with an additional mounting structure for the air duct 220, thus simplifying the structure.

[0063] In some embodiments of this application, the lower end of the air duct 220 is detachably connected to the mounting port 232.

[0064] When there is a large amount of food to be cooked, the air duct 220 can be installed on the chassis 230 to ensure that the food is baked evenly.

[0065] When there is a small amount of food to be cooked, or when the food is placed in a plate or other container, the air duct 220 can be removed from the base 230, and the plate or other container can be placed directly on the base 230.

[0066] The detachable installation method of the air duct 220 is designed to meet different cooking needs of users.

[0067] In some embodiments of this application, the air duct 220 includes an integrally structured upper section 222 and a lower section 223, which are arranged vertically along the height of the cooking cavity 211. A gasket 240 is fitted onto the lower section 223, which is inserted into the mounting opening 232, and the gasket 240 abuts against the peripheral wall surrounding the mounting opening 232. For example, the gasket 240 is a silicone gasket.

[0068] By setting gasket 240, the installation reliability between air duct 220 and chassis 230 is improved.

[0069] In some embodiments of this application, the outer diameter of the lower section 223 of the air guide tube is smaller than the outer diameter of the upper section 222 of the air guide tube, and a stepped portion 225 is formed between the first section and the second section of the air guide tube 220.

[0070] Reference Figure 8The gasket 240 includes a gasket part 241 and a gasket part 242, both having an integral structure. The gasket part 241 is fitted onto the outer periphery of the lower section 223 of the air duct, and the gasket part 242 extends horizontally from the top of the gasket part 241 to the outer periphery. (Refer to...) Figure 6 The washer part 242 is located between the step part 225 and the chassis 230.

[0071] Since both the chassis 230 and the air duct 220 are metal parts, and the surfaces of the metal parts are coated, by setting a first washer 241 and a second washer 242, direct contact between the two metal parts can be avoided to prevent coating wear.

[0072] In some embodiments of this application, reference is made to Figure 6 A first limiting part 224 is provided on the outer peripheral wall of the lower section 223 of the air duct, and a second limiting part 243 is provided on the inner peripheral wall of the gasket part 241. The first limiting part 224 and the second limiting part 243 cooperate to further improve the installation reliability between the gasket 240 and the air duct 220.

[0073] For example, the first limiting part 224 is an annular groove, and the second limiting part 243 is an annular protrusion, with the annular protrusion embedded in the annular groove.

[0074] In some embodiments of this application, the outer diameter of the air duct 220 decreases from top to bottom. This way, when food is placed around the air duct 220, more food is placed at the bottom, making the food stacked more stable and preventing the top food from tipping over due to excessive accumulation.

[0075] In some embodiments of this application, reference is made to Figure 4 The chassis 230 is provided with an insertion part 233, and the insertion part 233 is provided with flexible pads 234. The flexible pads 234 abut against the inner wall of the inner pot 210. The interference fit between the flexible pads 234 and the inner pot 210 realizes the fixed installation of the chassis 230 in the inner pot 210. Multiple flexible pads 234 are provided at intervals on the outer periphery of the chassis 230 to improve the stability of the chassis 230 in the inner pot 210.

[0076] For example, the flexible pad 234 is a silicone part, and the flexible pad 234 is provided with an insertion port. The insertion part 233 is inserted into the insertion port, and the chassis 230 is fixedly connected to the flexible pad 234.

[0077] The base 230 and the inner pot 210 are not fixedly connected. The base 230 can be removed to facilitate cleaning of the bottom of the inner pot 210.

[0078] In some embodiments of this application, reference is made to Figure 6There is a gap between the outer periphery of the base 230 and the inner wall of the inner pot 210, which increases the amount of hot air flowing upward into the upper space 212 in the lower space 213, and improves the circulation of hot air between the upper space 212 and the lower space 213, thereby helping to improve baking efficiency.

[0079] In some embodiments of this application, reference is made to Figure 2 The upper shell 112 contains a mounting bracket 113 and a heat shield 114, with the heat shield 114 positioned below the mounting bracket 113. A mounting area for electrical components is formed between the mounting bracket 113 and the top wall of the upper shell 112. The heat shield 114 serves to insulate against heat, preventing damage to the top electrical components from high temperatures.

[0080] In some embodiments of this application, the fan unit includes an upper fan 122, a lower fan 123, and a motor 121. The upper fan 122 and the lower fan 123 are both mounted on the shaft of the motor 121. The motor 121 is located above the mounting bracket 113, and the shaft of the motor 121 passes through the mounting bracket 113 and the heat insulation cover 114. The upper fan 122 is located above the mounting bracket 113, and the lower fan 123 is located below the heat insulation cover 114.

[0081] In some embodiments of this application, the heating element 130 is a heating tube, and the heating element 130 is fixedly disposed at the bottom of the heat insulation cover 114.

[0082] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0083] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
