[0037] In related technologies, air fryers are a common household cooking appliance that primarily utilizes an internal heating mechanism to generate heat, which, combined with an airflow mechanism, circulates within the air fryer's cavity to heat the food. Existing air fryers generate a downward airflow, where the upper surface of the food directly contacts the high-temperature airflow, but the lower surface remains in contact with the frying basket. This results in the lower surface of the food not being fully exposed to the high-temperature airflow, causing uneven cooking, affecting the food's texture, and leading to a poor user experience.

[0038] Reference Figure 1 As shown in Figure 6, the air fryer according to an embodiment of the present invention includes a shell assembly 100, a pot body 200, a frying basket 300, a heating assembly 400, and an air supply mechanism. The shell assembly 100 has a receiving cavity 110. The pot body 200 is connected to the shell assembly 100 and has a cooking cavity 210. The air outlet 120 of the receiving cavity 110 communicates with the cooking cavity 210. The frying basket 300 is disposed in the cooking cavity 210. The frying basket 300 includes a base 310 and a plurality of protrusions 320. The plurality of protrusions 320 are spaced apart, and each protrusion 320 includes a support portion 322 and a connecting portion 521 321. The connecting portion 521 321 connects the protrusion 320 and the support portion 322. The connecting portion 521 321 has a plurality of first through holes 3211, which are spaced apart circumferentially along the protrusions 320. The support portion 322 has at least one second through hole 3221. The base 310 is spaced apart from the inner wall of the cooking cavity 210 to form a first channel 220. The base 310 is spaced apart from the bottom wall of the cooking cavity 210 to form a second channel 230. The first channel 220, the first through hole 3211, and the second through hole 3221 are all connected to the second channel 230. The heating component 400 is located in the receiving cavity 110. The air supply mechanism is located in the receiving cavity 110. The airflow blown out by the air supply mechanism passes through the heating component 400 and enters the cooking cavity 210 through the air outlet 120. The airflow enters the first channel 220 and the second channel 230 sequentially along the inner wall of the cooking cavity 210, and finally flows back from the first through hole 3211 and the second through hole 3221 to contact the lower surface of the food. In this way, the airflow can first fry and grill the lower surface of the food, and then fry and grill the outer and upper surfaces of the food, so that the food is fried and grilled evenly, which can improve the taste of the food and thus improve the user experience.

[0039] For example, when the air fryer is working, the food is placed on the support 322, the heating element 400 is activated, and the airflow blown out by the air supply mechanism forms a high-temperature airflow after passing through the heating element 400. The airflow enters the cooking chamber 210 from the air outlet 120 and moves downward along the inner peripheral wall of the cooking chamber 210. Then, the airflow passes through the first channel 220 and the second channel 230 in sequence, and finally flows upward back from the first through hole 3211 and the second through hole 3221 to contact the lower surface of the food. The airflow can first fry and grill the lower surface of the food, and then fry and grill the outer peripheral and upper surfaces of the food, so that the food is fried and grilled evenly, which can improve the taste of the food and thus improve the user experience.

[0040] It should be noted that heating component 400 can be a heating tube, heating element, or other heating component, and there are no restrictions on this.

[0041] In some embodiments of this utility model, the width of the connecting part 521321 gradually decreases from bottom to top, which can prevent the connecting part 521321 from contacting the food, thereby increasing the contact area between the airflow and the food to ensure that the food is baked evenly.

[0042] It should be noted that the outer peripheral surface of the connecting part 521321 is either an arc surface or a sloped surface, and no restrictions are imposed here.

[0043] In some embodiments of this utility model, the base 310 is provided with a plurality of spaced third through holes 311, which are connected to the second channel 230 and can increase the air volume of the second channel 230 so that the food is baked evenly and the taste of the food is improved.

[0044] In some embodiments of this utility model, a plurality of support blocks 312 are provided on the side of the seat 310 away from the protrusion 320. The plurality of support blocks 312 are spaced apart along the circumference of the seat 310. The support blocks 312 abut against the bottom wall of the cooking cavity 210 so that the bottom wall of the cooking cavity 210 is spaced apart from the seat 310, which is conducive to the airflow entering the second air duct from the first channel 220.

[0045] Understandably, when traditional air fryers fry or grill food, the food is placed on the frying basket 300, and the part of the food in contact with the frying basket 300 is not fully fried or grilled, resulting in uneven frying or grilling.

[0046] Reference Figure 7In some embodiments of this utility model, a cavity 323 is formed between the connecting part 521321 and the supporting part 322. The first through hole 3211 and the second through hole 3221 are both connected to the second channel 230 through the cavity 323. From bottom to top, the width of the cavity 323 gradually decreases, which can guide the airflow from the first through hole 3211 to flow in the direction close to the second through hole 3221, so that the airflow from the first through hole 3211 can flow into the space between the food and the supporting part 322. The part of the food that contacts the supporting part 322 is also fried by the airflow, ensuring that the food is baked evenly.

[0047] For example, the air inlet of the first through hole 3211 is located on the side wall of the cavity 323. When the airflow enters the cavity 323 through the second channel 230, the width of the cavity 323 gradually decreases from bottom to top, causing the airflow to tend to flow towards the center of the support part 322. The airflow can gather upward along the side wall of the cavity 323, guiding the airflow from the first through hole 3211 to flow in a direction close to the second through hole 3221. This allows the airflow from the first through hole 3211 to flow between the food and the support part 322, and the part of the food that contacts the support part 322 is also fried and roasted by the airflow, ensuring that the food is roasted evenly.

[0048] In some embodiments of this utility model, a guide section 324 is provided between the connecting part 521321 and the base 310. The guide section 324 is used to guide the airflow in the second channel 230 into the cavity 323, which can increase the air intake of the cavity 323 and thus improve the frying and grilling efficiency of the air fryer.

[0049] For example, the air guide 324 has a rounded corner structure, and the width of the air guide 324 gradually decreases from bottom to top, which can guide the airflow in the second channel 230 into the cavity 323, increase the air intake of the cavity 323, and thus improve the frying and grilling efficiency of the air fryer.

[0050] As another implementation, the guide portion 324 can also be a chamfered structure, which is not limited here.

[0051] In some embodiments of this utility model, the housing assembly 100 includes a housing 101 and an air guide plate 102. The housing 101 has a cavity, and the air guide plate 102 is disposed in the cavity to divide the cavity into a receiving cavity 110 and a cooking cavity 210. An air outlet 120 is disposed on the air guide plate 102, and multiple air outlets 120 are arranged at intervals along the circumferential direction. The airflow blown out by the air supply mechanism can enter the cooking cavity 210 from all directions, thereby ensuring that the food is baked evenly.

[0052] In some embodiments of this utility model, a return hole is provided in the middle of the air guide plate 102. The airflow in the cooking chamber 210 returns to the receiving chamber 110 through the return hole, which can recycle the airflow and thus improve the frying and baking efficiency of the air fryer.

[0053] Reference Figure 8 In some embodiments of this utility model, the air supply mechanism includes a centrifugal fan blade 520 and a drive member 510. The output shaft of the drive member 510 is connected to the centrifugal fan blade 520. When the centrifugal fan blade 520 rotates, the airflow enters the first channel 220 and the second channel 230 sequentially along the inner peripheral wall of the cooking cavity 210. The airflow generated by the centrifugal fan blade 520 can flow along the center away from the centrifugal fan blade, so that the airflow can enter the first channel 220 along the inner peripheral wall of the cooking cavity 210.

[0054] For example, the centrifugal fan blade 520 includes a connecting piece 521 and a plurality of fan blades 522 spaced apart along the axis surrounding the connecting piece 521. The end of the fan blade 522 away from the connecting piece 521 is provided with a centrifugal protrusion 523. The centrifugal protrusion 523 extends in a direction away from the drive member 510. The airflow generated by the centrifugal protrusion 523 and the fan blades 522 can flow along the center away from the centrifugal fan blade, so that the airflow can enter the first channel 220 along the inner peripheral wall of the cooking cavity 210.

[0055] In some embodiments of this utility model, the air supply mechanism further includes a heat insulation component, which includes a heat insulation box 540 and a heat dissipation fan blade 541. The output shaft of the drive member 510 passes through the heat insulation box 540, and the heat dissipation fan blade 541 is disposed inside the heat insulation box 540 and connected to the output shaft of the drive member 510. This can reduce the heat transfer from the heating component 400 to the drive member 510, thereby improving the service life of the drive member 510 and improving the safety of using the air fryer.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention 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 invention.
