The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0037] The present application will be described in further detail below with reference to the drawings.

[0038] Please refer to Figures 1 to 9 The air fryer 100 provided by the embodiments of the present application includes a pot body 10, a heating structure 20 and a frying basket 30.

[0039] Among them, please refer to Figures 1 to 4, the pot main body 10 has a heating cavity 11 and a cooking cavity 12, the heating cavity 11 is located above the cooking cavity 12, and the air inlet 13 is arranged on the pot main body 10; the heating structure 20 is installed in the heating cavity 11 and includes a fan cover 21, a fan 24 arranged on the fan cover 21, and a heating pipe 22 arranged in the fan cover 21; the fan cover 21 forms a flow cavity 211 in which air flows, and the flow cavity 211 includes a conical upper flow part 212 and a columnar lower flow part 213; the upper flow part 212 is provided with a communication port 214; the heating pipe 22 is installed in the lower flow part 213 in a ring shape, and the bottom of the lower flow part 213 is provided with a plurality of circumferentially arranged air outlets 215; the air inlet 13, the communication port 214, the flow cavity 211, and the air outlets 215 are sequentially communicated; and the frying basket 30 is detachably installed in the cooking cavity 12.

[0040] When the heating structure 20 heats the food in the frying basket 30, the air flow is driven by the fan 24 to flow into the fan cover 21 from the air inlet 13 of the pot main body 10, is first dispersed through the conical upper flow part 212, and then enters the columnar lower flow part 213, is heated by the heating pipe 22 installed in the lower flow part 213, and is finally discharged from the circumferentially arranged air outlets 215 formed in the bottom of the lower flow part 213. In this way, since the air flow can flow into the frying basket 30 in a 360-degree direction, the hot air flow can more uniformly contact the food, so that the food is evenly heated and the taste of the food is ensured.

[0041] Understandably, the flow cavity 211 includes an upper flow cavity 2121 and a lower flow cavity 2131; the conical upper flow part 212 forms the upper flow cavity 2121; and the columnar lower flow part 213 forms the lower flow cavity 2131, and the heating pipe 22 is arranged in the lower flow cavity 2131.

[0042] Further, in order to ensure that the hot air flows out uniformly, the plurality of air outlets 215 are uniformly arranged on the bottom of the lower flow part 213, that is, the air outlet area of each air outlet 215 is the same, and the spacing between every two adjacent air outlets 215 is the same. In this way, when the hot air flow flows out of the air outlets 215, it can uniformly flow to the food, ensuring the uniformity of the heating of the food.

[0043] Specifically, in the present embodiment, four air outlets 215 are arranged on the lower flow part 213, and the central angle of each air outlet 215 is close to 90 degrees. In other embodiments, other numbers of air outlets 215 can also be arranged, such as three, five, six, or more, which are not limited herein.

[0044] Further, please refer to Figure 4 , Figures 7 to 9In order to install the heating pipe 22, the connecting arms 216 are arranged between every two air outlets 215, and the heating structure 20 further comprises at least one support 23 arranged in the lower flow cavity 2131 of the lower flow part 213 and used for supporting the heating pipe 22, and the support 23 corresponds to the position of the connecting arm 216, and the connecting arm 216 is not provided with the air outlet 215, so that the structural strength is greater, and the supporting strength of the heating pipe 22 is ensured.

[0045] In the embodiment, four air outlets 215 are arranged, and one connecting arm 216 is arranged between every two air outlets 215, so that one support 23 is arranged at the position of each connecting arm 216, and the heating structure 20 comprises four supports 23.

[0046] In order to ensure the temperature of the heated air, the heating pipe 22 comprises a plurality of heating rings 221 arranged along the height direction of the lower flow part 213, and a plurality of clamping grooves 231 are arranged on the support 23, one heating ring 221 is clamped in one clamping groove 231, so that the support 23 is installed and fixed to the heating pipe 22; and since the plurality of heating rings 221 are arranged in parallel along the vertical direction, the air is heated by the plurality of heating rings 221, and the heating temperature of the air flow is ensured.

[0047] In one embodiment of the utility model, in order to ensure the stability of the air pressure, the air inlet area of the communicating port 214 and the total air outlet area of the plurality of air outlets 215 are equal, since the larger the opening of the communicating port 214 is, the smaller the air flow pressure is, so that the air pressure when the air flows out of the air outlet 215 is influenced; when the opening of the communicating port 214 is small, the air flow is small, and the air flow discharged from the air outlet 215 is not enough, by setting the air inlet area of the communicating port 214 and the total air outlet area of the plurality of air outlets 215 to be equal, the stability of the air pressure when the air flows out is ensured, and the air flow is ensured.

[0048] In the embodiment, please refer to Figure 4 , Figure 8 and Figure 9To facilitate the forming of the hood 21, the hood 21 in this embodiment has a recess in the direction away from the frying basket 30. This reduces the weight of the entire hood 21. However, during the high-temperature cooking process, oil splatters may occur, and the oil may fly into the recess of the hood 21 and adhere to the inner wall of the hood 21 facing the frying basket 30. To facilitate cleaning the hood 21, the air fryer 100 also includes a tray 40. The tray 40 is connected to the lower flow part 213 and is used to cover the recess. The lower surface of the tray 40 is a flat surface 43. By providing a tray 40 with a flat surface 43, when oil stains adhere to the lower surface of the tray 40, they can be wiped with a cloth. This method of cleaning the recessed side wall makes it easier to clean the heating structure 20.

[0049] When installing the tray 40 and the hood 21, the tray 40 and the lower flow section 213 can be detachably connected for easy cleaning of the tray 40 later, for example, by plugging, snapping or bolting, so that the tray 40 can be disassembled later.

[0050] Specifically, in order to ensure the stability of the installation of the tray 40, the hood 21 is provided with a connecting post 217, which extends into the recess. The tray 40 is provided with a docking post 41, which is located on the side of the tray 40 away from the blast basket 30 and is used to connect with the docking post 41 by bolts. Thus, when the tray 40 and the hood 21 are installed, the stability of the tray 40 installed on the hood 21 is ensured by bolt connection.

[0051] Please refer to Figure 5 , Figure 6 , Figure 8 as well as Figure 9 In this embodiment, the hood 21 is designed so that airflow is required inside it. Therefore, the hood 21 includes an inner cover 219 and an outer cover 218 covering the inner cover 219. A flow cavity 211 for forming gas is formed between the outer cover 218 and the inner cover 219. That is, the flow cavity 211 includes an upper flow cavity 2121 and a lower flow cavity 2131. The inner cover 219 forms the above-mentioned recess in the direction away from the frying basket 30.

[0052] Furthermore, to ensure the stability of the airflow, when setting the inner cover 219 and the outer cover 218, the outer cover 218 is provided with a connecting port 214. The outer cover 218 includes a first inclined section 2181 and a first straight wall section 2182. The inner cover 219 includes a second inclined section 2191 and a second straight wall section 2192. The second inclined section 2191 and the first inclined section 2181 are arranged parallel to each other and correspond to the conical upper flow portion 212. The second straight wall section 2192 and the first straight wall section 2182 are arranged parallel to each other and correspond to the annular lower flow portion 2. In this way, by setting the second inclined section 2191 and the first inclined section 2181 in a parallel manner, when the airflow flows into the flow cavity 211 from the connecting port 214, the airflow is evenly distributed between the two inclined walls, thereby ensuring the stability of the airflow when it flows out from the air outlet 215.

[0053] Specifically, in this embodiment, the inner cover 219 is provided with the aforementioned connecting post 217. Bolts pass through the connecting post 217 along the side of the inner cover 219 facing the outer cover 218 to connect with the mating post 41. This allows the bolts to be hidden within the flow cavity 211, preventing long-term exposure to food and the bolts from rusting due to contact with water or gasoline stains after cooking. For ease of injection molding of the inner cover 219, please refer to [link to relevant documentation]. Figure 8 and Figure 9 The inner cover 219 includes a first sub-cover 2193 and a second sub-cover 2194. The first sub-cover 2193 forms the second inclined section 2191 and is provided with the connecting post 217. The second sub-cover 2194 forms the second straight wall section 2192. Thus, the inner cover 219, which is provided in separate parts, allows the connecting post 217 to be injection molded on the first sub-cover 2193. During installation, the first sub-cover 2193 and the second sub-cover 2194 are installed, and then the connecting post 217 and the docking post 41 are connected by bolts to install the tray 40 on the first sub-cover 2193. Then, the outer cover 218 is placed on the inner cover 219.

[0054] Furthermore, to facilitate the installation between the first cover 2193 and the second cover 2194, a support platform 2195 is provided on the side of the second cover 2194 facing the first cover 2193. The first cover 2193 overlaps the support platform 2195, and a guide sleeve 2197 is provided on the first cover 2193. The guide sleeve 2197 passes through the opening of the support platform 2195. The entire inner cover 219 is installed by overlapping the support platform 2195 and the first cover 2193. To prevent the first cover 2193 from moving relative to the second cover 2194, a flange 42 is provided on the outer periphery of the tray 40. The second cover 2194 forms a clearance opening corresponding to the flange 42. The flange 42 is located in the clearance opening, thereby limiting the movement of the first cover 2193.

[0055] In this embodiment, the second cover 2194 of the inner cover 219 has an air outlet 215. Specifically, the second cover 2194 extends outward from the edge away from the first cover 2193, forming an extension 2196. This extension 2196 has the air outlet 215 and supports the support member 23 and the heating tube 22. When the entire fan cover 21 is installed on the main body, the outer cover 218 is provided with connecting ears 2183. The heating structure 20 is installed on the main body by bolting the connecting ears 2183 to the main body.

[0056] The air fryer 100 described above has multiple air outlets 215 evenly distributed at the bottom of the lower flow section 213, ensuring that the hot airflow from the outlets 215 flows evenly towards the food, guaranteeing uniform heating. A support member 23 is provided within the lower flow cavity 2131 of the lower flow section 213 to support the heating element 22, thus mounting the heating element 22 inside the fan shroud 21. The air inlet area of ​​the connecting port 214 and the total air outlet area of ​​the multiple outlets 215 are set to be equal to ensure the stability of the airflow pressure and the airflow rate. The lower flow section 213 has multiple air outlets 215 evenly distributed at the bottom of the lower flow section 213. The tray 40 can be wiped with a cloth after oil stains adhere to its lower surface. This method of cleaning the concave sidewalls facilitates the cleaning of the heating structure 20. The tray 40 and the lower flow section 213 are detachably connected, which facilitates the subsequent disassembly and cleaning of the tray 40. By setting the second inclined section 2191 of the inner cover and the first inclined section 2181 of the outer cover 218 to be parallel, when the airflow flows into the flow cavity 211 from the connecting port 214, the airflow is evenly distributed between the two inclined walls, thereby ensuring the stability of the airflow when it flows out of the air outlet 215.
