For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] The cooking device 100 of this utility model is described below with reference to the accompanying drawings.

[0037] Reference Figure 7 , Figure 8 A cooking device 100 according to an embodiment of the present utility model includes: a shell 10, a fan blade 20, a heating element 40, and a food carrier 30.

[0038] The housing 10 has a cooking space 11. A fan blade 20 is rotatably disposed within the cooking space 11. A heating element 40 is disposed within the cooking space 11. The food carrier 30 has at least a first food space 2 and a second food space 3 for placing food. The food carrier 30 also has a first guide hole 332 and a second guide hole 333. The fan blade 20, the first food space 2, and the second food space 3 are arranged sequentially from top to bottom. The first guide hole 332 connects the cooking space 11 and the first food space 2, and the second guide hole 333 connects the cooking space 11 and the second food space 3. The area of ​​the first guide hole 332 is A1, the area of ​​the second guide hole 333 is A2, the area of ​​the side containing the first guide hole 332 on the first food space 2 is B1, and the area of ​​the side containing the second guide hole 333 on the second food space 3 is B2. A2 / B2 > A1 / B1.

[0039] It is understood that the cooking space 11 is used to cook ingredients. The fan blade 20 rotates to disturb the air and form an airflow. The heating element 40 heats the airflow. The fan blade 20, the first ingredient space 2 and the second ingredient space 3 are arranged from top to bottom. The hot airflow flows from top to bottom. The hot airflow flows into the first ingredient space 2 through the first guide hole 332 and into the second ingredient space 3 through the second guide hole 333, heating the ingredients in the ingredient space.

[0040] In related technologies, air fryers have fan blades and heating elements. The fan blades circulate hot air heated by the heating element into the cooking space, where the hot air heats the food. However, air fryers often cook unevenly, requiring users to shake the food during use to ensure it cooks evenly.

[0041] In this embodiment of the invention, the fan blade 20, the first food space 2, and the second food space 3 are arranged from top to bottom, so that the hot airflow flows from top to bottom. Multiple food spaces are provided, and the hot airflow is introduced into the food spaces through guide holes. Considering that the second food space 3 is farther from the fan blade 20 than the first food space 2, the hot airflow speed is slower, and less hot airflow enters the second food space 3 through the second guide hole 333. The ratio A2 / B2 is set to A1 / B1, which controls the total amount of hot airflow in the first food space 2 and the second food space 3, so that the food in different food spaces is heated evenly, thereby improving the cooking uniformity.

[0042] For example, the food space has multiple layers with the same spacing between them. That is, the height of the first food space 2 is equal to the height of the second food space 3, and B1 is equal to B2. Because the second food space 3 is farther away from the fan blade 20, the speed of the hot airflow is slowed down. Therefore, the opening area of ​​the second guide hole 333 is increased so that more hot airflow can enter the second food space 3, thereby improving the uniformity of cooking.

[0043] Alternatively, there can be multiple airflow holes, which are spaced apart in the direction away from the fan blade 20. The areas of the multiple airflow holes are the same, and A1 equals A2, which increases the volume of the first food space 2, that is, increases the height of the first food space 2, i.e. increases B1. Although more hot airflow enters the first food space 2, the volume of the first food space 2 is larger, thereby improving the uniformity of cooking.

[0044] Specifically, the cooking device 100 can be an air fryer, and the food carrier 30 can be a frying basket or frying drum with drainage holes; it can also be a frying drum with multiple baking trays inside and drainage holes on the frying drum; or the cooking device 100 can be an air fryer oven with multiple baking trays inside.

[0045] According to the cooking device 100 of this utility model embodiment, by setting the fan blade 20, the first food space 2, and the second food space 3 from top to bottom, the hot airflow flows from top to bottom. In addition, multiple food spaces are set, and A2 / B2>A1 / B1 is set to control the total amount of hot airflow in the first food space 2 and the second food space 3, so that the food in different food spaces is heated evenly, thereby improving the cooking uniformity.

[0046] Reference Figure 7 , Figure 8 In some embodiments, the cooking space 11 is provided with an opening, and the food carrier 30 is retractably provided in the opening. The food carrier 30 has a first surface 32 and a second surface 33 adjacent to the first surface 32. The fan blade 20 is provided on one side of the first surface 32, and the first guide hole 332 and the second guide hole 333 are provided on the second surface 33.

[0047] The food carrier 30 is retractable and located at the opening. The food carrier 30 is pulled out of the opening to place food into the food space, and then pushed into the cooking space 11 for cooking. The food carrier 30 has a first surface 32 and a second surface 33 adjacent to the first surface 32. A fan blade 20 is located on one side of the first surface 32. The second surface 33 has a guide hole that connects the food space and the cooking space 11, guiding airflow into the food space to contact the food.

[0048] In the above scheme, the air guide hole is set on the second surface 33, and the fan blade 20 is located on one side of the first surface 32. The first surface 32 and the second surface 33 are adjacent. The airflow flows from one side of the fan blade 20 to the adjacent side of the food carrier 30, and then enters the food space to cook the food through the air guide hole. This makes the food carrier 30 better matched with the fan blade 20, and the airflow direction is continuous and complete, improving the overall performance.

[0049] Specifically, the first surface 32 is the top surface of the food carrier 30, and the second surface 33 is the side surface of the food carrier 30. The airflow enters the food space from the side surface of the food carrier 30 from the fan blade side downwards; or, the first surface 32 is the side surface of the food carrier 30, and the second surface 33 is the top surface of the food carrier 30. The airflow enters the food space from the top surface of the food carrier 30 from the fan blade side.

[0050] Specifically, the food carrier 30 is a frying basket, which can be pulled out or pushed in from the opening.

[0051] Reference Figure 7 In some embodiments, the first guide hole 332 and the second guide hole 333 extend horizontally, B1 = B2, and A2 > A1.

[0052] Where A2>A1, that is, the area of ​​the second guide hole 333 is greater than the area of ​​the first guide hole 332.

[0053] In particular, multiple guide holes are arranged sequentially in the direction away from the fan blade 20. Among the multiple guide holes, the guide holes away from the fan blade 20 have a larger opening area, which reduces the resistance to airflow.

[0054] In the above scheme, by setting the opening area of ​​the second guide hole 333 to be larger than that of the first guide hole 332, the resistance of the second guide hole 333 to the airflow is reduced, making the airflow guided by the first guide hole 332 and the second guide hole 333 more uniform, thereby allowing food at different heights in the food space to come into contact with an equal amount of airflow, thus improving the uniformity of cooking.

[0055] For example, the food space has multiple layers with the same spacing between them. That is, the height of the first food space 312 is equal to the height of the second food space 313, and B1 is equal to B2. Because the second food space 313 is farther away from the fan blade 20, the speed of the hot airflow is slowed down. Therefore, the opening area of ​​the second guide hole 333 is increased so that more hot airflow enters the second food space 313, improving the uniformity of cooking.

[0056] Specifically, the fan blade 20 is positioned above the food carrier 30, with the first guide hole 332 and the second guide hole 333 arranged sequentially from top to bottom; or, the fan blade 20 is positioned below the food carrier 30, with the first guide hole 332 and the second guide hole 333 arranged sequentially from bottom to top; of course, the fan blade 20, the first guide hole 332, and the second guide hole 333 can also be arranged in other orientations, which will not be elaborated here.

[0057] Specifically, there can be more guide holes, such as three or four. Multiple guide holes can be arranged sequentially in the direction away from the fan blade 20, with similar effects, which will not be elaborated here.

[0058] Reference Figure 7 In some embodiments, the first guide hole 332 and the second guide hole 333 extend horizontally, A1 = A2, and B1 > B2.

[0059] Where A1 = A2 and B1 > B2, that is to say, the areas of the multiple guide holes are the same, but the volumes of the spaces for different ingredients are different.

[0060] In the above scheme, by setting A2 / B2>A1 / B1, the amount of hot airflow in different food spaces is balanced, making the cooking of food in different food spaces more uniform and improving the cooking uniformity.

[0061] Specifically, there are multiple guide holes, which are spaced apart in the direction away from the fan blade 20. The areas of the multiple guide holes are the same, A1 equals A2, which increases the volume of the first food space 312, that is, increases the height of the first food space 312, i.e. increases B1. Although there is more hot air entering the first food space 312, the volume of the first food space 312 is larger, thereby improving the uniformity of cooking.

[0062] In some embodiments, the food carrier 30 is provided with a plurality of trays 311, which are arranged at intervals in sequence in the direction away from the fan blade 20.

[0063] The heating element 40 heats the surrounding air, and the fan blades agitate the fan to guide the hot air into the food space to cook the food. Multiple trays 311 are placed in the food space, and the hot air cooks the food on the multiple trays 311.

[0064] In the above scheme, multiple trays 311 are set in the direction away from the fan blade 20 to make full use of the food space and place more food.

[0065] Specifically, when the cooking device 100 is a fryer-type device, the food carrier 30 is the fryer; when the cooking device 100 is an oven-type device, the food carrier 30 is the inner wall of the cooking cavity.

[0066] In some specific embodiments, the opening areas of the first guide hole 332 and the second guide hole 333 are controlled so that the food farther away from the heating element 40 comes into contact with more hot air. It can be understood that the food closer to the heating element 40 is affected by more heat. By controlling the opening areas of the first guide hole 332 and the second guide hole 333, the food in different positions is affected by the same amount of heat, thereby further improving the cooking uniformity.

[0067] Reference Figure 1 , Figure 7 and Figure 8In some specific embodiments, the housing 10 includes an inner housing 15 and an outer housing 16. The inner housing 15 defines a cooking space 11. The fan blade 20 is connected to a drive motor 151. The inner housing 15 has a support member 153 on the side opposite to the fan blade 20. The drive motor 151 is mounted on the support member 153. The drive motor 151 is also connected to a heat dissipation fan blade 152.

[0068] Specifically, the food carrier 30 and the inner shell 15 together define the outflow ventilation channel 154. The guide part 13 straightens the airflow and blows it out from the side. It passes through the outflow ventilation channel 154, enters the frying basket through the guide hole on the side wall of the frying basket, blows over the surface of the food, and forms a circulation through the return air vent.

[0069] In some embodiments, the housing 10 is provided with a guide member 12, the fan blade 20 is disposed within the guide member 12, and the guide member 12 communicates with the cooking space 11. The housing 10 has a guide portion 13, which is disposed within the guide member 12 or is integrally formed with the guide member 12. The guide portion 13 extends toward a set direction L1, and the set direction L1 and the rotation direction L2 of the fan blade 20 are configured at an acute angle.

[0070] It is understood that the cooking space 11 is used for cooking ingredients, and the fan blades 20 rotate to create airflow, making the temperature within the cooking space 11 uniform. The fan blades 20 are located inside the guide member 12, which constrains the airflow direction and guides the airflow to the cooking space 11.

[0071] Reference Figure 2 , Figure 3 The angle between the direction L1 and the rotation direction L2 is set to θ, where θ is less than 90°.

[0072] In related technologies, air fryers have fan blades and heating elements. The fan blades circulate hot air heated by the heating elements into the cooking space, where the hot air heats the food. However, in these technologies, the hot air circulates around the fan blades during rotation, preventing it from flowing effectively into the cooking space, thus reducing cooking efficiency.

[0073] In this embodiment of the present invention, a guide portion 13 is provided inside the guide member 12. The setting direction L1 of the guide portion 13 and the rotation direction L2 of the fan blade 20 are configured at an acute angle. The rotating airflow around the fan blade 20 flows to the guide portion 13, and the airflow moves away from the fan blade 20 along the guide portion 13. The guide portion 13 plays a guiding role, guiding the hot air around the fan blade 20 away from the fan blade 20. The guide portion 13 rectifies the airflow and blows the airflow out from the side of the fan blade 20, reducing the speed of the airflow in the circumferential direction. This forms a loop in the cooking space 11 to heat the food, improving the problem of the airflow swirling around the fan blade 20, and allowing the hot air to flow into the cooking space 11 faster and in greater quantities, thus improving cooking efficiency.

[0074] Specifically, the guide portion 13 is adjacent to the fan blade 20, and the guide portion 13 is located beside the fan blade 20. The airflow around the fan blade 20 flows to contact the guide portion 13.

[0075] The guide portion 13 may be disposed within the guide member 12, and the guide portion 13 may be spaced apart from the inner wall of the guide member 12; or the guide portion 13 and the guide member 12 may be constructed as an integral part. The guide portion 13 may be a single part or multiple parts, with multiple guide portions 13 arranged around the fan blade 20.

[0076] Specifically, the guide portion 13 extends away from the fan blade 20. The guide portion 13 has a certain length, and the rotation of the fan blade 20 is usually clockwise or counterclockwise. The angle between the setting direction L1 of the guide portion 13 and the rotation direction L2 is in the range of 0 to 90°. For example, the angle between the setting direction L1 of the guide portion 13 and the rotation direction L2 is 45°, or 60°, or other angles, which will not be elaborated here.

[0077] According to the embodiment of the present invention, the cooking device 100 provides a guide portion 13 in the guide member 12, which guides the airflow around the fan blade 20, causing the airflow around the fan blade 20 to move away from the fan blade 20, reducing the circumferential speed of the airflow, and forming a loop to heat the food in the cooking space 11. This improves the problem of the airflow swirling around the fan blade 20, allowing hot air to flow into the cooking space 11 faster and in greater quantities, thereby improving cooking efficiency.

[0078] Reference Figures 1 to 4 In some embodiments, the guide portion 13 is provided with a first guide surface 131, and the guide member 12 is constructed as a first side surface 1221 relative to the inner wall of the guide portion 13. In the direction away from the fan blade 20, the distance between the first guide surface 131 and the first side surface 1221 gradually increases.

[0079] The first guide surface 131 plays a guiding role, guiding the direction of airflow. The guide part 13 is located inside the guide member 12 and is opposite to the inner wall of the guide member 12. Part of the inner wall of the guide member 12 is named the first side surface 1221. The first guide surface 131 is inclined relative to the first side surface 1221. In the direction away from the fan blade 20, the distance between the first guide surface 131 and the first side surface 1221 gradually increases.

[0080] In the above scheme, by setting the first guide surface 131 to be inclined relative to the first side surface 1221, the first guide surface 131 guides and diffuses the airflow, making the airflow flow more smoothly.

[0081] Specifically, the guide portion 13 can be configured to be spaced apart from the inner wall of the guide member 12, and the guide portion 13 can be independent of the guide member 12, or a portion of the guide member 12 can be constructed as the guide portion 13.

[0082] Reference Figures 1 to 4 In some embodiments, the guide 12 includes a receiving portion 121 and an air outlet portion 122.

[0083] The fan blades 20 are disposed inside the housing 121. The air outlet 122 is connected to the housing 121 and the cooking space 11.

[0084] The guide portion 13 is further provided with a second guide surface 132. The second guide surface 132 is arc-shaped. One end of the second guide surface 132 is connected to the first guide surface 131, and the other end is connected to the receiving portion 121.

[0085] The guide member 12 is partially structured as a guide part 13. The fan blade 20 is disposed in the receiving part 121. One end of the air outlet 122 is connected to the receiving part 121 and the other end is connected to the cooking space 11, guiding the airflow to the cooking space 11. One end of the guide part 13 is connected to the receiving part 121 and the other end is connected to the air outlet 122. That is, one end of the first guide surface 131 is connected to the air outlet 122 and the other end is connected to the second guide surface 132. The end of the second guide surface 132 away from the first guide surface 131 is connected to the receiving part 121.

[0086] In the above solution, the second guide surface 132 is constructed as an arc shape. The arc-shaped structure of the second guide surface 132 makes manufacturing simpler, and compared with the sharp corner solution of the related technology, the arc-shaped structure of the present invention improves the stress situation.

[0087] Specifically, the guide 12 also has a second side 1222 opposite to the first side 1221. One end of the second side 1222 is connected to the first guide surface 131, the end of the first guide surface 131 away from the second side 1222 is connected to the second guide surface 132, and the end of the second guide surface 132 away from the first guide surface 131 is connected to the receiving portion 121.

[0088] Reference Figures 1 to 4 In some embodiments, there are multiple air outlets 122, and the multiple air outlets 122 are spaced apart along the circumferential direction of the receiving portion 121.

[0089] Multiple air outlets 122 are spaced apart along the circumferential direction of the receiving portion 121, and the airflow in the receiving portion 121 flows to the multiple air outlets 122, resulting in airflow in multiple directions.

[0090] In the above solution, by providing multiple air outlets 122 in the circumferential direction of the receiving section 121, the airflow is guided to flow in multiple directions by the multiple air outlets 122, so that the airflow flows smoothly and the cooking efficiency is improved.

[0091] For example, there are two air outlets 122, which are spaced apart in the circumferential direction of the receiving part 121 and are respectively connected to the receiving part 121, guiding the airflow to flow in two directions; or, there are three air outlets 122, which are spaced apart in the circumferential direction of the receiving part 121 and are respectively connected to the receiving part 121, guiding the airflow to flow in three directions; of course, there can be more air outlets 122, which will not be elaborated here.

[0098] The first air intake plate 141 protrudes from the mounting surface 14 and encloses a space. The fan blade 20 is located within the space enclosed by the first air intake plate 141. The first air intake plate 141 constrains the airflow. The second air intake plate 142 protrudes from the mounting surface 14 and encloses a space. One end of the space enclosed by the second air intake plate 142 is connected to the space inside the first air intake plate 141, and the other end is connected to the cooking space 11.

[0099] In the above scheme, by setting a first guide plate 141 and a second guide plate 142, the first guide plate 141 and the second guide plate 142 protrude from the mounting surface 14 to guide the airflow. The overall structure is relatively simple and convenient for rapid molding.

[0100] In some specific embodiments, the above-mentioned receiving portion 121 is a first guide plate 141, and the above-mentioned air outlet portion 122 is a second guide plate 142.

[0101] Reference Figure 1 , Figure 5 and Figure 6 In some specific embodiments, the first drainage plate 141 is constructed as an arc-shaped plate, with the center of curvature of any point on the arc-shaped plate located in the direction of the arc-shaped plate toward the fan blade 20, and the arc-shaped plate is configured to extend around the fan blade 20.

[0102] The curved plate surrounds the fan blade 20 and bends toward the fan blade 20, allowing airflow to flow along the inner wall of the curved plate.

[0103] In the above scheme, by setting an arc-shaped plate around the fan blade 20, the smooth surface of the arc-shaped plate guides the airflow, making the airflow smooth. The arc-shaped plate fits the fan blade 20, allowing the fan blade 20 to play its full role and improving the utilization rate.

[0104] Reference Figure 1 , Figure 5 and Figure 6 In some embodiments, the second diversion plate 142 includes a first diversion sub-plate 1421 and a second diversion sub-plate 1422. In the direction of airflow disturbance by the fan blade 20, the second diversion sub-plate 1422 is located downstream of the first diversion sub-plate 1421. The first diversion sub-plate 1421 is connected to the first diversion plate 141. One end of the guide portion 13 is connected to the second diversion sub-plate 1422, and the other end is connected to the first diversion plate 141.

[0105] The first guide plate 1421 and the second guide plate 1422 are arranged opposite to each other in the rotation direction L2 of the fan blade 20. The first guide plate 1421 and the second guide plate 1422 are arranged in sequence. The inner wall of the second guide plate 1422 faces the airflow, and the inner wall of the first guide plate 1421 faces away from the airflow. One end of the guide part 13 is connected to the second guide plate 1422, and the other end is connected to the first guide plate 141. The guide part 13 faces the airflow and guides the airflow.

[0106] In the above solution, by placing the guide portion 13 between the second guide plate 1422 and the first guide plate 141, with the guide portion 13 facing the airflow, compared to the solution where the guide portion 13 is placed in the middle of the first guide plate 1421 and the second guide plate 1422, the space between the guide portion 13 and the first guide plate 1421 in this embodiment of the utility model is larger, thereby allowing the airflow to flow smoothly and enabling the fan blade 20 to fully perform its function.

[0107] Specifically, the fan blade 20 rotates counterclockwise, the second diversion plate 1422 is located in front of the first diversion plate 1421, the left end of the guide part 13 is connected to the second diversion plate 1422, and the right end of the guide part 13 is connected to the first diversion plate 141. The airflow disturbed by the fan blade 20 flows directly towards the guide part 13, and the guide part 13 diverts the airflow and guides the airflow to the space between the first diversion plate 1421 and the second diversion plate 1422.
