[0023] In related technologies, air fryers have a cooking chamber and an air duct connecting to the cooking chamber. A heating element is installed inside the air duct, and hot air blown out by the heating element is blown into the cooking chamber through the air outlet of the air duct to cook food. Because the existing air duct blows air from only one direction, the food is not cooked evenly, which affects the taste of the food.

[0024] Reference Figures 1 to 6An embodiment of the present invention provides an air fryer including a pot body 100. The pot body 100 has a cooking cavity 110 and an air duct. The air duct includes an air inlet cavity 120, a middle cavity 130, and an air outlet cavity 140. The air outlet cavity 140 has multiple vents 141, which are spaced apart circumferentially along the air outlet cavity 140. The middle cavity 130 includes a first air outlet section 131, a second air outlet section 132, and a third air outlet section 133, which are separated from each other. The first air outlet section 131 has a first air inlet and a first air outlet. The second air outlet section 132... 2 has a second air inlet and a second air outlet, and the third air outlet section 133 has a third air inlet and a third air outlet. The first air inlet, the second air inlet and the third air inlet are all connected to the air inlet cavity 120, and the first air outlet, the second air outlet and the third air outlet are all connected to the air outlet cavity 140. The first air outlet, the second air outlet and the third air outlet are located at different positions around the air outlet cavity 140, so that hot air can be blown into the cooking cavity 110 from different directions, effectively expanding the hot air coverage area, ensuring that the food is heated evenly, thereby improving the taste of the food.

[0025] For example, when the air fryer is working, hot air enters the middle cavity 130 from the air inlet cavity 120. By dividing the middle cavity 130 into the first air outlet section 131, the second air outlet section 132, and the third air outlet section 133, and with the first air outlet, the second air outlet, and the third air outlet distributed at different positions around the air outlet cavity 140, hot air can be blown into the air outlet cavity 140 from different directions. Finally, it is blown into the cooking cavity 110 from multiple vents 141, effectively expanding the coverage of hot air, ensuring that the food is heated evenly, and thus improving the taste of the food.

[0026] It should be noted that the intermediate cavity 130 may also include a fourth air outlet section or a fifth air outlet section, etc., without limitation.

[0027] In this embodiment, the pot body 100 includes a shell 101 and a cover 102. The cooking cavity 110 and the air duct are both located on the shell 101. The cover 102 covers the air duct and is detachably connected to the shell 101, which makes it easy for users to clean the residue inside the air duct, keep the air outlet unobstructed, and avoid the accumulation of oil stains that affect the air outlet efficiency.

[0028] For example, the cover 102 can be detachably connected to the housing 101 by bolts or clips, which makes it easy for users to clean the residue inside the air duct, keep the air outlet unobstructed, and avoid the accumulation of oil stains that affect the air outlet efficiency.

[0029] In this embodiment, the pot body 100 also includes an annular partition 170, a first transparent plate 181, and a second transparent plate 182. The annular partition 170 is disposed in the air outlet cavity 140, and a viewing channel 171 is formed inside the annular partition 170. The cover 102 is provided with a first opening 1811, and the air outlet cavity 140 is provided with a second opening 1821. The two ends of the viewing channel 171 are respectively connected to the first opening 1811 and the second opening 1821. The first transparent plate 181 covers the first opening 1811, and the second transparent plate 182 covers the second opening 1821. The user can observe the cooking progress without opening the lid, which is convenient for the user.

[0030] For example, the annular partition 170 extends vertically, with its lower end connected to the second opening 1821 and its upper end connected to the first opening 1811. By setting a first transparent plate 181 and a second transparent plate 182 at the first opening 1811 and the second opening 1821 respectively, on the one hand, the user can observe the cooking progress through the viewing channel 171; on the other hand, the first transparent plate 181 and the second transparent plate 182 can prevent hot air in the cooking cavity 110 from escaping through the viewing channel 171, thereby reducing heat loss.

[0031] It should be noted that the first transparent panel 181 can be made of transparent or semi-transparent material, and the second transparent panel 182 can be made of transparent or semi-transparent material, without any restrictions.

[0032] In this embodiment, the pot body 100 also includes a first partition 150 and a second partition 160. The first partition 150 and the second partition 160 are disposed in the intermediate cavity 130 and are arranged side by side with intervals to divide the intermediate cavity 130 into a first air outlet section 131, a second air outlet section 132 and a third air outlet section 133. This can ensure that the hot air in the first air outlet section 131, the hot air in the second air outlet section 132 and the hot air in the third air outlet section 133 flow independently, avoid mutual interference, and thus improve the stability and controllability of hot air distribution.

[0033] For example, the first partition 150 and the second partition 160 are mirror-symmetrical. Both the first partition 150 and the second partition 160 have an arc-shaped structure and are arranged to extend circumferentially along the air outlet cavity 140. This allows the first partition 150 to guide the hot air in the air inlet cavity 120 into the first air outlet section 131, and the second partition 160 to guide the hot air in the air inlet cavity 120 into the third air outlet section 133. This ensures that the air volume of the first air outlet, the second air outlet, and the third air outlet is consistent, thereby ensuring that the food is baked evenly.

[0034] In this embodiment, the pot body 100 also includes a hot air assembly, which is disposed in the air inlet cavity 120. The hot air assembly includes a heater and a fan. The heater is used to heat the air in the air inlet cavity 120. The air blown out by the fan is heated into hot air by the heater and delivered to the first air outlet section 131, the second air outlet section 132 and the third air outlet section 133. By placing the heater and the fan in the air inlet cavity 120, the temperature of the hot air in the first air outlet section 131, the second air outlet section 132 and the third air outlet section 133 can be kept consistent to ensure that the food is baked evenly and thus improve the taste of the food.

[0035] In this embodiment, the air outlet cavity 140 is provided with a third partition and a fourth partition. The third partition is located between the first air outlet and the second air outlet, and the fourth partition is located between the second air outlet and the third air outlet. By setting the third partition and the fourth partition, the third partition and the fourth partition can isolate the hot air flowing into the air outlet cavity 140 from the second air outlet section 132, so as to prevent the hot air flowing into the second air outlet section 132 from flowing to the first air outlet and the third air outlet, avoid airflow interference, maintain the directionality of circumferential air outlet, and ensure that the food is baked evenly.

[0036] In this embodiment, an infrared heating element 220210 is provided inside the air outlet cavity 140. The infrared heating element 220210 is a corrugated tube and extends circumferentially along the air outlet cavity 140. The infrared rays emitted by the infrared heating element 220210 can irradiate the food surface through the vent 141. The infrared rays and hot air form a composite heating mode, which can realize dual heating of hot air and infrared radiation, thereby ensuring that the food surface is crispy.

[0037] Reference Figures 7 to 10 In this embodiment, the pot body 100 also includes a cooking component 300. The cooking component 300 is disposed in the cooking cavity 110 and is detachably connected to the pot body 100. The cooking component 300 is used to hold food, which makes it easy to put or take out food or clean the cooking component 300.

[0038] In this embodiment, the cooking component 300 includes an inner pot 310 and a frying basket 320 disposed in the inner pot 310. The inner pot 310 is provided with a receiving cavity 311, which has a third opening 312 and a return air vent 313. The third opening 312 is connected to the air outlet cavity 140, and the return air vent 313 is connected to the air inlet cavity 120. By providing the return air vent 313, the hot air in the cooking cavity 110 can flow back to the air inlet cavity 120 and be reheated by the hot air component, which can form a closed hot air circulation and improve the thermal energy utilization rate.

[0039] In this embodiment, the bottom walls of the frying basket 320 and the receiving cavity 311 are spaced apart to form a connecting channel 322. Along the vertical direction, at least a portion of the return air vent 313 is located between the bottom walls of the frying basket 320 and the receiving cavity 311. The frying basket 320 is provided with a plurality of clearance holes 321 for the connecting channel 322. On the one hand, hot air can penetrate the food layer through the clearance holes 321, promoting the hot air to penetrate the food from top to bottom and achieve three-dimensional heating. On the other hand, by setting the return air vent 313 between the bottom walls of the frying basket 320 and the receiving cavity 311, it is beneficial to quickly discharge waste gas and accelerate waste heat recovery.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
