[0033] The following is for reference. Figures 1-6 According to an embodiment of the present invention, the air fryer 100, by setting a turbulence fan 131 to interfere with the gas flow direction, blows more gas around the food, heats the food evenly, and thus improves the cooking efficiency of the food.

[0034] like Figures 1-6 As shown, an air fryer 100 according to an embodiment of the present invention includes: a device body 1.

[0035] The main body of the device 1 has a cooking cavity 11, a first mounting cavity 12 and a second mounting cavity 13. The cooking cavity 11 and the first mounting cavity 12 are distributed along a first direction and the second mounting cavity 13 is distributed along a second direction. The cooking cavity 11 is provided with a food support 111. The first mounting cavity 12 is provided with a heating element 121 and a heating fan 122. The second mounting cavity 13 is provided with a turbulence fan 131. The first direction and the second direction intersect.

[0036] Specifically, the air fryer 100 can be an air fryer or other types of air fryer 100. The device body 1 is the shell structure of the air fryer 100, which includes a cooking cavity 11, a first mounting cavity 12 and a second mounting cavity 13. The first mounting cavity 12 and the second mounting cavity 13 are arranged in different directions relative to the cooking cavity 11. For example, the first mounting cavity 12 and the cooking cavity 11 are distributed along a first direction, and the second mounting cavity 13 and the cooking cavity 11 are distributed along a second direction. The first direction can be a vertical direction or a horizontal direction, and the second direction can be a horizontal direction or a vertical direction. Alternatively, the angle between the first direction and the second direction is an acute angle. Various arrangement methods can meet various usage requirements of the air fryer 100.

[0037] Furthermore, the food support 111 in the cooking cavity 11 is used to place and support food. The food support 111 can be a baking pan, frying pan, etc. The food support 111 can be fixedly connected to the cooking cavity 11. When in use, the food to be cooked is placed in the food support 111 for cooking. The heating element 121 in the first mounting cavity 12 is used to heat the air, and the heating fan 122 is used to drive the airflow. The heating fan 122 and the heating element 121 are spaced apart along the first direction. The heating element 121 can be a heating tube. After the heating tube is powered on, it can heat the surrounding gas. After the heating fan 122 rotates, it can drive the hot airflow. The turbulence fan 131 in the second mounting cavity 13 is used to drive the airflow in the second mounting cavity 13.

[0038] The heating fan 122 is used to drive the airflow to circulate between the first mounting cavity 12 and the cooking cavity 11, and the turbulence fan 131 is used to drive the airflow to circulate between the second mounting cavity 13 and the cooking cavity 11.

[0039] Specifically, the heating fan 122 is installed along a first direction, and the deflector fan 131 is installed along a second direction. The first mounting cavity 12 and the second mounting cavity 13 are respectively connected to the cooking cavity 11. In this way, during the food cooking process, the heating fan 122 drives the hot airflow in the first mounting cavity 12 into the cooking cavity 11 to heat the food, and then returns to the first mounting cavity 12. The hot airflow circulates between the first mounting cavity 12 and the cooking cavity 11. At the same time, the deflector fan 131 drives part of the hot airflow in the cooking cavity 11 into the second mounting cavity 13, and the hot airflow then enters the cooking cavity 11 from the second mounting cavity 13. In this way, the hot airflow circulates between the cooking cavity 11 and the second mounting cavity 13. The food is heated by the hot airflow in the two directions mentioned above, which improves the cooking efficiency.

[0040] Therefore, the heating fan 122 can drive the airflow to circulate in the first direction, enabling the food to be heated from one side of the food support 111. The deflector fan 131 is used to interfere with the airflow direction in the cooking cavity 11, causing part of the airflow in the cooking cavity 11 to circulate in the second direction, enabling the food to be heated from the other side of the food support 111. In this way, more hot airflow can be evenly distributed around the food, so as to heat the food better and more evenly, thereby cooking food quickly and conveniently and improving the performance of the air fryer 100. Moreover, the setup is simple and highly practical.

[0041] According to the embodiment of the present invention, the air fryer 100 can change the airflow direction in the cooking cavity 11 by setting a turbulence fan 131, so that more airflow flows to the food. In conjunction with the heating fan 122, the airflow in the cooking cavity 11 is evenly distributed around the food, so that the food is heated evenly, thereby improving the cooking efficiency of the food and enhancing the user experience.

[0042] In some embodiments, the device body 1 is provided with a first air outlet 123 and a first air return 124 that are open in a first direction. The first air outlet 123 and the first air return 124 are spaced apart and respectively connected between the first mounting cavity 12 and the cooking cavity 11.

[0043] Specifically, such as Figure 1As shown, the main body 1 of the device can be constructed as a cylinder, a cuboid, etc. The first air outlet 123 is used to allow the airflow from the first mounting cavity 12 to flow into the cooking cavity 11, and the first return air section 124 is used to send the airflow from the cooking cavity 11 back to the first mounting cavity 12. Both the first air outlet 123 and the first return air section 124 are constructed to be open along the first direction and are respectively connected to the first mounting cavity 12 and the cooking cavity 11. The first air outlet 123 and the first return air section 124 can be provided as round holes, square holes, etc. The first air outlet 123 and the first return air section 124 are located above the cooking cavity 11 and are spaced apart. The first air outlet 123 and the first return air section 124 can be spaced apart along the first direction, and the first air outlet 123 and the first return air section 124 can also be arranged in a ring. The first air outlet 123 is located outside the first return air section 124, which is conducive to the airflow of the first air outlet 123 and the return air of the first return air section 124.

[0044] The airflow directions of the first air outlet 123 and the first air return 124 are different, as shown in the following... Figure 2 As shown, driven by the heating fan 122, the hot airflow in the first mounting cavity 12 enters the cooking cavity 11 from the first air outlet 123, and the hot airflow in the cooking cavity 11 flows back to the first mounting cavity 12 from the first return air outlet 124, realizing the circulation of hot airflow between the first mounting cavity 12 and the cooking cavity 11. The airflow direction is circulated along the first direction, realizing the circulatory heating of food.

[0045] And / or, the device body 1 is provided with a second air outlet 132 and a second air return 133 that are open in the second direction, the second air outlet 132 and the second air return 133 being spaced apart and respectively connected between the second mounting cavity 13 and the cooking cavity 11.

[0046] Specifically, the second air outlet 132 is used to allow airflow from the second mounting cavity 13 into the cooking cavity 11, and the second air return 133 is used to return airflow from the cooking cavity 11 to the second mounting cavity 13. Both the second air outlet 132 and the second air return 133 are configured to be open along the second direction and are respectively connected to the second mounting cavity 13 and the cooking cavity 11. The second air outlet 132 and the second air return 133 can be configured as round holes, square holes, etc. The second air outlet 132 and the second air return 133 are located on the side of the cooking cavity 11 and are spaced apart. The second air outlet 132 and the second air return 133 can be spaced apart along the first direction.

[0047] The airflow directions of the second air outlet 132 and the second air return 133 are different, as shown in the following... Figure 2As shown, driven by the turbulence fan 131, the hot airflow in the second mounting cavity 13 enters the cooking cavity 11 from the second air outlet 132, and the hot airflow in the cooking cavity 11 flows back to the second mounting cavity 13 from the second return air outlet 133, realizing the circulation of hot airflow between the second mounting cavity 13 and the cooking cavity 11. The airflow direction is circulated along the second direction to achieve circulatory heating of the food.

[0048] This allows a portion of the hot airflow to circulate along the first direction and another portion to circulate along the second direction, ensuring a continuous supply of hot air around the food and enabling it to heat up more quickly.

[0049] In some embodiments, the first air outlet 123 and the first air return 124 are both distributed opposite to the food support 111 along a first direction. Specifically, the food support 111 is located in the middle of the cooking cavity 11 and is the same as the center of the heating tube and the heating fan 122. The first direction can be a vertical direction. The first air outlet 123 and the first air return 124 are located above the cooking cavity 11, and the food support 111 is located below the cooking cavity 11. The first air outlet 123 and the first air return 124 are distributed opposite to the food support 111. In this way, during the cooking process, the hot airflow from the first air outlet 123 can flow toward the food to effectively heat the food, and the hot airflow from the cooking cavity 11 can flow back into the first mounting cavity 12 from the first air return 124, which helps to increase the airflow velocity between the first mounting cavity 12 and the cooking cavity 11, thereby increasing the cooking speed of the food.

[0050] In some embodiments, in the projection along the second direction, the projection of the second air outlet 132 and the projection of the second air return 133 are both located on the upper side of the food support 111.

[0051] Specifically, in the projections along the second direction, the projections of the second air outlet 132, the second return air outlet 133, and the food support 111 are spaced apart to achieve the functions of air intake and air exhaust, respectively. Furthermore, the projections of both the second air outlet 132 and the second return air outlet 133 are located on the upper side of the food support 111. Thus, driven by the turbulence fan 131, the flow of hot air within the cooking cavity 11 is disrupted. The hot airflow in the upper space of the cooking cavity 11 is driven to the second mounting cavity 13 through the second return air outlet 133 and enters the upper side of the food support 111 through the second air outlet 132. This results in a uniform distribution of hot airflow on the upper side of the food. The circulating airflow increases the amount of hot air on the food surface, helping to heat the food evenly and improving heating efficiency. The design is simple, highly functional, and provides better heating results.

[0052] Therefore, through the above-mentioned settings, more airflow on the upper side of the cooking cavity 11 can flow to the food surface to penetrate the food, thereby improving the heating efficiency of the food. This is applicable to situations where the lower part of the inner pot forming the cooking cavity 11 is not perforated. At the same time, since the lower part of the inner pot is not perforated, there will be no oil leakage, thus improving the user experience.

[0053] In some embodiments, the projections of the second air outlet 132 can be located on both sides of the food support 111, so that the hot airflow on the upper side and the hot airflow on the lower side of the food support 111 can circulate in the cooking cavity 11, so that the hot airflow is evenly distributed on the upper and lower sides of the food. Under the circulation of the airflow, the food is heated in at least two directions, which can help the food be heated evenly and improve the heating efficiency of the food.

[0054] In some embodiments, the projection of the second air outlet 132 may be located on the lower side of the food support 111, and a ventilation hole may be provided on the inner pot at a position on the lower side of the food support 111 along the vertical direction. Hot airflow can enter the cooking cavity 111 through the ventilation hole and penetrate the food support 111 and return to the second mounting cavity 13 through the second return air outlet 133, so that the hot airflow is evenly distributed on the lower side of the food. Combined with the heating fan 122, the food is heated in at least two directions under the circulation of airflow, which can help the food be heated evenly and improve the heating efficiency of the food.

[0055] In some embodiments, the second return air section 133 is configured as a plurality of spaced-apart return air holes, the cross-sectional area of ​​each return air hole is smaller than the cross-sectional area of ​​the second air outlet section 132, and the sum of the cross-sectional areas of the plurality of return air holes is greater than or equal to the cross-sectional area of ​​the second air outlet section 132.

[0056] Specifically, the second return air section 133 and the second air outlet section 132 are important structures for the circulation of hot air within the cooking cavity 11. Multiple return air vents are located on the inlet side of the turbulence fan 131, such as... Figure 3 As shown, multiple return air vents are spaced apart and evenly spaced, and are distributed around the axis of the baffle fan 131. The baffle fan 131 is located at the center of the cooking cavity 11 in the second direction, which facilitates the driving of hot airflow by the baffle fan 131 and improves the efficiency of hot airflow driving. There can be one or more second air outlets 132. In this embodiment, there is one second air outlet 132, the center of which is located below the central axis of the baffle fan 131, facilitating rapid airflow from the second air outlet 132. The overall structure is symmetrical and regular.

[0057] The return air vents can be round, square, or other shapes, and the second return air section 133 can be square, elongated, or other shapes. Each return air vent has a smaller cross-sectional area than the second outlet section 132. This means that hot air enters the second mounting cavity 13 through multiple return air vents and then flows into the cooking cavity 11 through the second outlet section 132. This reduces the amount of grease and other substances entering the second mounting cavity 13 from the cooking cavity 11, thus acting as a filter. This ensures the cleanliness of the turbulence fan 131 and helps control the airflow of each return air vent, ensuring a balanced airflow. The sum of the cross-sectional areas of the multiple return air vents is greater than the cross-sectional area of ​​the second outlet section 132, ensuring overall return air efficiency. Even when dispersed into multiple return air vents, the return air capacity can be maintained or exceeded when a single outlet section is used, thereby improving the ability of the turbulence fan 131 to disperse hot air and increasing the heating efficiency of the food.

[0058] In some embodiments, the first air outlet 123 is configured as a plurality of spaced-apart air outlets distributed around the first return air section 124.

[0059] Specifically, in the first direction, the heating fan 122 and the heating element 121 are located at the center of the cooking cavity 11. Multiple air outlets are evenly spaced and distributed around the axis of the heating fan 122, which facilitates the driving of hot airflow by the heating fan 122 and improves the driving efficiency of hot airflow. The multiple air outlets can be round holes, square holes, etc., and the first return air section 124 can be square holes, elongated holes, etc., and there can be multiple first return air sections 124. The multiple first return air sections 124 can be distributed around the axis of the heating fan 122, and the multiple air outlets are distributed around the first return air sections 124. In this way, when the heating fan 122 is driven, axial return air and radial air outlet can be realized, and the hot airflow is transported along the outer area of ​​the heating fan 122 into the cooking cavity 11, which increases the flow range of the hot airflow in the cooking cavity 11, so that the hot airflow is evenly distributed on the food surface, and the food can be heated evenly and quickly. Its setting method is simple and the heating effect is better. Furthermore, by setting the first air outlet 123 and the first air return 124, the amount of grease and other substances in the cooking cavity 11 entering the first mounting cavity 12 can be reduced, which plays a filtering role and can ensure the cleanliness of the heating fan 122 and the heating element 121.

[0060] Furthermore, the arrangement of the first air outlet 123 and the first return air section 124 is not limited to that described in this embodiment, as long as the return air efficiency at the first return air section 124 can be guaranteed.

[0061] In some embodiments, the first direction is along the vertical direction, the first mounting cavity 12 is located above the cooking cavity 11, and the second direction is along the horizontal direction.

[0062] Specifically, the first direction is perpendicular to the second direction, such as... Figure 2As shown, the first mounting cavity 12 is located above the cooking cavity 11, and the two are connected in the vertical direction through the first air outlet 123 and the first air return 124. The second direction can be the front-back direction, the left-right direction, etc. In this embodiment, the second direction can be the front-back direction. The second mounting cavity 13 is located on the left, right, or rear side of the cooking cavity 11. In this embodiment, the second mounting cavity 13 is located on the rear side of the cooking cavity 11, and the two are connected in the front-back direction through the second air return 133 and the second air outlet 132. That is, the turbulence fan 131 in the second mounting cavity 13 can drive the hot airflow in the cooking cavity 11 to circulate in the front-back direction, and the heating fan 122 in the first mounting cavity 12 can drive the hot airflow to circulate in the vertical direction, which increases the contact area between the hot airflow and the food, improves the heating efficiency, and has a simple structure and low cost.

[0063] In some embodiments, the cooking cavity 11 has at least two heating spaces, which are distributed along a first direction and / or a second direction, and each heating space is provided with a food support 111.

[0064] Specifically, at least two heating spaces can be spaced apart along a first direction, and at least two heating spaces can be spaced apart along a second direction, and at least two heating spaces can be spaced apart along the first direction and the second direction respectively, which is suitable for different heating needs and different types of air fryers 100.

[0065] The cooking cavity 11 may have two heating spaces, which may be spaced apart along a first direction or a second direction to meet the heating requirements of the two heating spaces respectively in the first direction or the second direction. The cooking cavity 11 may also have multiple heating spaces, which may be spaced apart along only the first direction or the second direction, or multiple heating spaces may be spaced apart along both the first and second directions simultaneously to meet the heating requirements of multiple heating spaces in the first direction and / or the second direction. Each heating space is provided with a food support 111, and food may be placed in each food support 111. The food in each heating space is heated simultaneously by the main heating fan 122 and the turbulence fan 131 to achieve the cooking of multiple foods.

[0066] In some embodiments, at least two heating spaces are distributed along a first direction, and the volume of the upper heating space in a pair of adjacent heating spaces is greater than the volume of the lower heating space.

[0067] Specifically, in the vertical direction, at least two heating spaces are provided. The upper heating space has a larger volume, which allows for more hot airflow and enables the hot airflow to penetrate the food to heat it. The lower heating space has a smaller volume, which is smaller than the adjacent upper heating space, resulting in less hot airflow and a lower heating effect compared to the upper heating space.

[0068] In this arrangement, one upper heating space is close to the heating fan 122, and the other lower heating space is far from the heating fan 122. The food is placed on the food support 111, and the upper surface of the food can directly contact the hot airflow. The lower surface of the food needs to be heated through the heat transfer of the food support 111, which will affect the heating efficiency of the bottom of the food. This makes the food more effectively heated from the top. Furthermore, by setting the volume of the heating space close to the heating fan 122 to be larger than the volume of the heating space far from the heating fan 122, the heating effect of the upper heating space can be improved. The arrangement is reasonable, and the heating efficiency of the food is good.

[0069] In some embodiments, at least two heating spaces are distributed along a second direction, and the volume of the heating space closer to the turbulence fan 131 is greater than the volume of the heating space farther from the turbulence fan 131.

[0070] Specifically, in the front-to-back direction, at least two heating spaces are provided. The heating space closer to the deflector fan 131 has a larger volume, resulting in more hot airflow in the heating space closer to the deflector fan 131, and more hot airflow can penetrate the food to heat the food. The heating space farther away from the deflector fan 131 has a smaller volume, which is smaller than the adjacent heating space closer to the deflector fan 131, resulting in less hot airflow in the heating space on the front side and a lower heating effect compared to the heating space on the rear side.

[0071] The deflector fan 131 can interfere with the airflow direction within the cooking cavity 11, driving more hot airflow to flow in the heating space near the deflector fan 131, resulting in better heating of food in the rear heating space. Furthermore, by setting the volume of the heating space near the heating fan 122 to be larger than the volume of the heating space away from the heating fan 122, the airflow deflection effect of the heating space near the deflector fan 131 can be improved. In addition, the combination of the heating space volume near the heating fan 122 being larger than the heating space volume away from the heating fan 122 can improve the heating effect of the food surface and the food in the heating space near the deflector fan 131. Its arrangement is reasonable, and the heating efficiency of the food is good.

[0072] In some embodiments, the turbulence fan 131 is movably installed in the second mounting cavity 13, and the air outlet direction of the turbulence fan 131 is along the second direction or forms an air outlet angle with the second direction, the air outlet angle being less than or equal to 90°.

[0073] Specifically, by movably installing the deflector fan 131 inside the second mounting cavity 13, the air outlet direction of the deflector fan 131 can be moved. When the deflector fan 131 moves inside the second mounting cavity 13, the air outlet direction of the deflector fan 131 can be along the second direction, and the air outlet direction of the deflector fan 131 can form an air outlet angle with the second direction, thereby meeting the air outlet requirements of the deflector fan 131 in different directions.

[0074] Specifically, the outlet angle between the deflector fan 131 and the second direction is less than 90°, and the deflector fan 131 has axial air intake and radial air outlet. This ensures that the airflow forming an angle with the second direction enters the cooking cavity 11 after the deflector fan 131 rotates. Furthermore, the outlet angle between the deflector fan 131 and the second direction is set to be equal to 90°. Figure 4 As shown, its air intake direction is the second direction. At this time, the turbulence fan 131 can drive a large amount of airflow in the cooking cavity 11 to circulate in the second mounting cavity 13 and the cooking cavity 11. At this time, the airflow can be driven to be large and the turbulence effect is good. Also, the air outlet direction of the turbulence fan 131 is set to form an air outlet angle of 90° with the second direction. Its air intake direction is perpendicular to the second direction. It can drive a small amount of airflow in the second mounting cavity 13 to flow into the cooking cavity 11. At this time, the airflow can be driven to be small and can be applied when the turbulence fan 13 is not needed.

[0075] Therefore, by adjusting the air outlet and air inlet directions of the turbulence fan 131 as described above, the driving range of the turbulence fan 131 on the airflow is expanded, and the flow rate of hot air entering the cooking chamber 11 is increased, thereby improving the cooking efficiency of food.

[0076] And when the air outlet direction of the turbulence fan 131 forms an air outlet angle of 90° with the second direction, such as Figure 5 and Figure 6 As shown, in actual use, the exhaust direction of the turbulence fan 131 can move along the second direction towards both sides, and the maximum range of motion is within... Figure 5 and Figure 6 Within a certain range, so as to effectively expand the turbulence range of the turbulence fan 131.

[0077] The air outlet angle formed by the turbulence fan 131 and the second direction can be 90°, 80°, 70°, 50°, 30°, 20°, etc., and the specific air outlet angle can be adjusted according to actual needs.

[0078] In some embodiments, the air fryer 100 further includes a turbulence drive 136, a turbulence fan 131 is mounted on the output end of the turbulence drive 136, a rotating bracket 137 is provided in the second mounting cavity 13, the turbulence drive 136 is rotatably mounted on the rotating bracket 137, and is adapted to drive the turbulence fan 131 to rotate relative to the rotating bracket 137.

[0079] In this way, the turbulence drive 136 can move relative to the rotating bracket 137, and the turbulence drive 136 is connected to the turbulence fan 131. That is, when the turbulence drive 136 rotates, it can drive the turbulence fan 131 to rotate relative to the rotating bracket 137, thereby changing the airflow direction of the turbulence fan 131.

[0080] Specifically, the turbulence drive component 136 is the power source for the turbulence fan 131. The turbulence drive component 136 can be configured as a drive motor, and the turbulence fan 131 is connected to the output end of the drive motor, which can drive the rotation of the turbulence fan 131. The second mounting cavity 13 is provided with a rotating bracket 137, which is detachably connected to the second mounting cavity 13. The turbulence drive component 136 is rotatably connected to the middle of the rotating bracket 137, and the rotating bracket 137 can accommodate the installation of the turbulence drive component 136. Through this rotatable connection, the turbulence drive component 136 can rotate within the second mounting cavity 13.

[0081] Among them, such as Figures 4-6 As shown, the rotating bracket 137 extends vertically and has a rotation center at its center. The turbulence drive 136 is connected to the rotation center, allowing the turbulence drive 136 to move centrally within the second mounting cavity 13. This allows the turbulence drive 136 to drive the turbulence fan 131 to rotate vertically around a second direction, and the turbulence drive 136 can drive the turbulence fan 131 to rotate clockwise or counterclockwise. This expands the turbulence range of the turbulence fan 31 within the vertical range, improving the airflow driving effect. Furthermore, the turbulence drive 136 can also be configured to drive the turbulence fan 131 to rotate horizontally, further expanding the turbulence range of the turbulence fan 31 within the vertical range. The configuration is versatile and can be flexibly set according to space and airflow requirements.

[0082] In some embodiments, the second mounting cavity 13 includes an inner sub-cavity 134 and an outer sub-cavity 135, which are spaced apart along a second direction. The turbulence fan 131 is located in the inner sub-cavity 134, and a turbulence drive member 136 is provided in the outer sub-cavity 135. The turbulence drive member 136 is used to drive the turbulence fan 131 to rotate.

[0083] Specifically, the inner sub-cavity 134 is used to install the turbulence fan 131, and the outer sub-cavity 135 is used to install the turbulence drive component 136. The inner sub-cavity 134 and the outer sub-cavity 135 are spaced apart along the second direction. Both the inner sub-cavity 134 and the outer sub-cavity 135 can be constructed as cylindrical cavities. The inner sub-cavity 134 is distributed close to the cooking cavity 11, such as... Figure 2 As shown, the outer sub-cavity 135 and the inner sub-cavity 134 protrude rearward. The turbulence drive 136 can be configured as a drive motor, which is detachably installed inside the outer sub-cavity 135. The turbulence fan 131 is located inside the inner sub-cavity 134, and the output shaft of the drive motor extends into the inner sub-cavity 134 and is poweredly connected to the turbulence fan 131, thus connecting the drive motor and the turbulence fan 131. This prevents hot airflow in the inner sub-cavity 134 from entering the outer sub-cavity 135 during cooking, which would affect the normal operation of the turbulence drive 136.

[0084] Therefore, the drive motor drives the turbulence fan 131 to rotate at high speed, which can continuously drive the hot airflow to circulate between the cooking cavity 11 and the inner sub-cavity 134, thereby achieving continuous heating of the food.

[0085] In some embodiments, a reflector 125 is further provided in the first mounting cavity 12. The reflector 125 divides the first mounting cavity 12 into a first sub-cavity 126 and a second sub-cavity 127 distributed along a first direction. A main drive 128 and a cooling fan 129 are provided in the first sub-cavity 126. A heating element 121 and a heating fan 122 are located in the second sub-cavity 127. The main drive 128 is used to drive the cooling fan 129 and the heating fan 122 to rotate.

[0086] Specifically, the reflector 125 has excellent heat reflectivity, reflecting the heat generated by the heating element 121, thereby improving heating efficiency. The reflector 125 is detachably installed in the first mounting cavity 12, with its open side facing the heating element 121. The reflector 125 divides the first mounting cavity 12 into a first sub-cavity 126 and a second sub-cavity 127, which are spaced apart along a first direction. Both the first sub-cavity 126 and the second sub-cavity 127 can be constructed as cylindrical cavities. The second sub-cavity 127 is distributed close to the cooking cavity 11. Figure 2 As shown, the main drive unit 128 can be configured as a drive motor, which is detachably installed inside the first sub-cavity 126. The heating fan 122 and the heating element 121 are located in the second sub-cavity 127. The output shaft of the drive motor extends along the first direction to the second sub-cavity 127 and is poweredly connected to the heating fan 122, thus realizing the connection between the drive motor and the heating fan 122. In this way, the hot airflow in the second sub-cavity 127 can be prevented from entering the first sub-cavity 126 during the cooking process, which would affect the normal operation of the main drive unit 128.

[0087] Therefore, the drive motor drives the heating fan 122 to rotate at high speed, which continuously drives the hot airflow to circulate between the cooking chamber 11 and the second sub-chamber 127, achieving continuous heating of the food. Furthermore, the reflector 125 reflects the heat generated by the heating element 121 towards the cooking chamber 11, causing some of the hot airflow to flow towards the first air outlet 123. This guides the airflow direction, improves the energy utilization of the hot airflow, and thus improves the food heating efficiency. The overall structure is safe and reliable.

[0088] Furthermore, the cooling fan 129 is located inside the first sub-cavity 126, and the drive motor is powered by the cooling fan 129. The rotation of the drive motor 129 drives the cooling fan 129 to rotate, which in turn drives the airflow to rotate. During long-term operation or high-power operation, the electronic components and heating elements of the air fryer 100 can be prevented from overheating, thereby avoiding damage and improving the service life of the product.

[0089] Among them, such as Figure 3 As shown, the air fryer 100 also includes a frying basket 112, inside which a food support 111 is connected for placing food, and as... Figure 1 As shown, a handle is connected to the outside of the frying basket 112. The user can operate the handle to extend or retract the frying basket 112 relative to the main body of the equipment. This makes the operation convenient and ensures the safety of the cooking process.
