For example, it can be fixedly connected, detachably connected, or integrally constructed; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or internal communication between two devices, elements or components. For those of ordinary skill in the art, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific situation.

[0042] In addition, the terms "first", "second" and the like are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not intended to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise stated, the meaning of "multiple" is two or more.

[0043] With the increasing concern about healthy diet, air fryers, as a new type of kitchen appliance, have gradually entered thousands of households. Air fryers use high-speed circulating hot air to fry food. Compared with traditional fried food, air fryers can significantly reduce the oil content in food while maintaining the deliciousness of food, providing a healthier way of cooking for users.

[0044] However, the air fryer technology in the related art has certain limitations. On the one hand, the air fryer usually only configures one frying barrel. In the process of cooking multiple food materials, due to the flow of hot air, different types of food materials are prone to flavor mixing, which not only affects the taste of the food materials, but also reduces the cooking experience. On the other hand, when the volume of the food material to be cooked deviates from the volume of the cooking cavity, the hot air may not act evenly on the food material, and energy is wasted.

[0045] Therefore, how to ensure the cooking effect of food materials while improving the cooking efficiency of the air fryer and preventing food materials from flavor mixing and sticking is a problem to be solved in the field of air fryer technology.

[0046] As shown in Figures 1 to 4 , the embodiment of the present application provides an air fryer 1, which comprises: a body 10, a first containing cavity 101a and a second containing cavity 102a are formed in the body 10; a first hot air assembly 20 is arranged in the body 10 and located in the first containing cavity 101a; a second hot air assembly 30 is arranged in the body 10 and located in the second containing cavity 102a; a first frying barrel 40 is arranged in the first containing cavity 101a in a detachable manner, and the first frying barrel 40 comprises a first cooking cavity 401; a second frying barrel 50 is arranged in the second containing cavity 102a in a detachable manner, and the second frying barrel 50 comprises a second cooking cavity 501, and the volume of the second cooking cavity 501 is different from that of the first cooking cavity 401.

[0047] As shown in Figure 1 , the body 10 can be the main structure of the air fryer 1 to provide structural support and protection for the working components of the air fryer 1. The body 10 can be made of heat-resistant materials, such as stainless steel or thermoplastic plastic.

[0048] As shown in Figure 1 , the body 10 can comprise a relatively independent first containing cavity 101a and a second containing cavity 102a. The first containing cavity 101a and the second containing cavity 102a are used to contain the first frying barrel 40 and the second frying barrel 50, respectively.

[0049] The body 10 can comprise a height direction, a length direction and a width direction, which are perpendicular to each other or tend to be perpendicular. The length direction can be the direction of the user side of the air fryer 1, and the width direction can be the side direction of the air fryer 1.

[0050] Optionally, the first containing cavity 101a and the second containing cavity 102a can be arranged along the height direction, that is, the first containing cavity 101a and the second containing cavity 102a can be arranged vertically.

[0051] Optionally, the first accommodating cavity 101a and the second accommodating cavity 102a can also be arranged along the length direction, that is, the first accommodating cavity 101a and the second accommodating cavity 102a can be arranged left and right.

[0052] As shown in Figure 2 and Figure 3 , the air fryer 1 comprises a first frying barrel 40 and a second frying barrel 50, the first frying barrel 40 is adapted to the first accommodating cavity 101a, and the second frying barrel 50 is adapted to the second accommodating cavity 102a. The first frying barrel 40 is arranged in the first accommodating cavity 101a in a removable manner, and the second frying barrel 50 is arranged in the second accommodating cavity 102a in a removable manner. The first frying barrel 40 can comprise a first cooking cavity 401 for accommodating food materials, and the second frying barrel 50 can comprise a second cooking cavity 501 for accommodating food materials.

[0053] It is worth noting that the first frying barrel 40 and the second frying barrel 50 are arranged in the air fryer 1, which can be more suitable for the scene of cooking multiple food materials at the same time. Different types of food materials can be placed in the first frying barrel 40 and the second frying barrel 50 respectively, and cooking can be completed in the relatively independent first cooking cavity 401 and the second cooking cavity 501. Different types of food materials will not cause odor mixing and adhesion, so that the user can cook different food materials at the same time, and the use scene of the air fryer 1 is enriched.

[0054] Further, as shown in Figure 4 , the volume of the first cooking cavity 401 is different from the volume of the second cooking cavity 501, that is, the volume of the first cooking cavity 401 and the second cooking cavity 501 is different.

[0055] It can be understood that the volume of the cooking cavity is related to the cooking efficiency. In the case of heating the same volume and quantity of food materials and the same cooking parameters, the smaller the volume of the cooking cavity, the higher the circulating efficiency of the hot air generated by the heating device, and correspondingly, the higher the efficiency of the food material maturation, and more energy saving.

[0056] For example, in the case of only needing to heat a small amount of food materials, the user can choose the frying barrel with smaller volume between the first frying barrel 40 and the second frying barrel 50. Compared with the air fryer in the related art which only has a single frying barrel with relatively large volume, the use of the smaller volume frying barrel in the air fryer 1 provided by the present application to cook small amount or small volume food materials can make the food materials mature faster, thereby saving energy and improving cooking efficiency at the same time.

[0057] In addition, the air fryer 1 provided by the embodiment of the present application can also use the frying barrel with larger volume to cook large quantity or large volume food materials, or use different frying barrels to cook large quantity food materials and small quantity food materials respectively, so as to enrich the use scene of the air fryer 1.

[0058] For example, the user can cook large volume or large portion of food materials, such as a whole chicken, in the large fryer basket, and cook small portion of snacks or children's meals, such as French fries, in the small fryer basket, and select appropriate cooking programs or cooking parameters according to the food materials to be cooked to adapt to different types or portions of food materials. In this way, not only the cooking efficiency of the air fryer 1 is improved, but also the air fryer 1 is more suitable for the diversified dietary needs in family life.

[0059] As shown in Figure 4 The air fryer 1 further comprises a first hot air assembly 20 and a second hot air assembly 30, which are respectively used for heating food materials accommodated in the first fryer basket 40 and the second fryer basket 50.

[0060] Optionally, the first hot air assembly 20 can comprise a first heating member 201 and a first fan assembly. In the height direction, the first heating member 201 is located between the first fan assembly and the first fryer basket 40, so that the heat energy generated by the first heating member 201 can be rapidly and uniformly distributed in the first cooking cavity 401 through the airflow generated by the first fan assembly, which helps the food materials to be uniformly cooked.

[0061] Optionally, the first heating member 201 can be a heat pipe, a microwave heating member or an infrared heating member, etc.

[0062] Optionally, the second hot air assembly 30 can comprise a second heating member 301 and a second fan assembly, so that the heat energy generated by the second heating member 301 can be rapidly and uniformly distributed in the second cooking cavity 501 through the airflow generated by the second fan assembly, which helps the food materials to be uniformly cooked.

[0063] Optionally, the second heating member 301 can be a heat pipe, a microwave heating member or an infrared heating member, etc.

[0064] In this way, the air fryer 1 provided by the embodiments of the present application can ensure that different types of food materials can be cooked in one cooking process to avoid cross-contamination or adhesion between different types of food materials. At the same time, since the volumes of the first cooking cavity 401 and the second cooking cavity 501 are different, the user can select to use the larger volume fryer basket or the smaller volume fryer basket according to the volume and portion of the food materials to be cooked, which not only enriches the use scenarios of the air fryer 1, but also saves energy consumption, improves the overall use efficiency and convenience of the air fryer 1 while ensuring the cooking effect.

[0065] In some embodiments, as shown in Figure 1 and Figure 4As shown, the first accommodating cavity 101a and the second accommodating cavity 102a are arranged along the height direction of the body 10; the first accommodating cavity 101a is located above the second accommodating cavity 102a, and the volume of the first cooking cavity 401 is smaller than that of the second cooking cavity 501.

[0066] Specifically, the first accommodating cavity 101a and the second accommodating cavity 102a are arranged along the height direction, and the first accommodating cavity 101a is located above the second accommodating cavity 102a.

[0067] Notably, in the kitchen environment where the air fryer 1 is used, the vertical space is often more easily utilized than the horizontal space. By arranging the first accommodating cavity 101a and the second accommodating cavity 102a along the height direction, the vertical space of the kitchen can be better utilized without increasing the area occupied by the countertop of the air fryer 1. Compared with the way of arranging the first accommodating cavity 101a and the second accommodating cavity 102a along the length direction, the first accommodating cavity 101a and the second accommodating cavity 102a arranged along the height direction can save the countertop space in the environment where the air fryer 1 is used, and is more friendly to improving the space utilization of the kitchen environment.

[0068] Further, the volume of the first cooking cavity 401 is smaller than that of the second cooking cavity 501, i.e., the second frying basket 50 with a relatively large volume and a relatively heavy weight after placing food materials is located at the bottom of the first frying basket 40, and the first frying basket 40 with a relatively small volume and a relatively light weight after placing food materials is located at the top of the second frying basket 50. Such a layout structure can improve the overall stability of the air fryer 1 and reduce the center of gravity of the air fryer 1, thereby avoiding the risk of overturning caused by the high center of gravity of the air fryer 1.

[0069] As introduced above, the first accommodating cavity 101a is adapted to the first frying basket 40, and the second accommodating cavity 102a is adapted to the second frying basket 50. Thus, since the volume of the first cooking cavity 401 is smaller than that of the second cooking cavity 501, the volume of the first accommodating cavity 101a is also smaller than that of the second accommodating cavity 102a, so as to ensure the compactness of the structure of the air fryer 1.

[0070] In some embodiments, the air fryer 1 further comprises a mesh rack. The mesh rack can be separately arranged in the second frying basket 50, so that the mesh rack can separate the second cooking cavity 501 with a relatively large volume into two cooking areas, i.e., a first cooking area and a second cooking area, thereby more fully utilizing the second cooking cavity 501 with a relatively large volume.

[0071] For example, food materials can be placed in the first cooking area and the second cooking area respectively, so as to increase the spacing between the food materials, which is helpful to more uniformly distributing the hot air in the cooking area, so that the food materials are heated more uniformly, and the cooking quality is improved.

[0072] In some embodiments, asFigure 4 As shown, the air fryer 1 can include a first control device 60. The first control device 60 can include a touch panel and a processor, etc. The touch panel can receive preset cooking modes or custom cooking parameters such as temperature and time set by the user through touch operation. The processor as the core component of the first control device 60 is used to receive the instructions input by the user through the touch panel, and adjust the working parameters of the first hot air assembly 20 and the second hot air assembly 30 according to the preset algorithm to achieve the best cooking effect.

[0073] In addition, the first control device 60 can also be connected with the user's mobile phone through Wi-Fi or Bluetooth, so that the user can remotely control the air fryer 1 through the mobile phone, view the cooking progress, etc.

[0074] The first control device 60 is electrically connected with the first hot air assembly 20, and the first control device 60 can control the independent work of the first hot air assembly 20, that is, the first hot air assembly 20 can work independently.

[0075] In some embodiments, as shown, Figure 4 As shown, the first control device 60 is arranged in the first accommodating cavity 101a, and the first control device 60 is located in the projection range of the first hot air assembly 20 projected along the width direction of the body 10.

[0076] The first control device 60 can be arranged along the height direction, and the first control device 60 is located in the projection range of the first hot air assembly 20 projected to the vertical plane.

[0077] The first control device 60 can be arranged beside the first hot air assembly 20. Since the first hot air assembly 20 has a certain height along the height direction, arranging the first control device 60 beside the first hot air assembly 20 can avoid the first control device 60 from occupying additional space along the height direction in the body 10.

[0078] Further, the first control device 60 can be located in the projection range of the first hot air assembly 20 projected to the vertical plane, so as to fully utilize the internal space of the first accommodating cavity 101a, so that the first control device 60 is free from occupying additional valuable space along the height direction of the first accommodating cavity 101a, and ensures that the air fryer 1 can be further miniaturized along the height direction. In some embodiments, the air fryer 1 further includes a second control device 61. The second control device is electrically connected with the second hot air assembly 30, so that the second hot air assembly 30 can work independently.

[0079] The second control device 61 can be arranged along the height direction, and the second control device 61 is located in the projection range of the second hot air assembly 30 projected to the vertical plane.

[0080] The second control device 61 can be arranged at the side of the second hot air assembly 30. Since the second hot air assembly 30 has a certain height in the height direction, arranging the second control device 61 at the side of the second hot air assembly 30 can avoid the second control device 61 from occupying additional space in the machine body 10 in the height direction.

[0081] Further, the second control device 61 can be located within the projection range of the second hot air assembly 30 projected onto the vertical plane, so as to fully utilize the internal space of the first accommodating cavity 101a, so that the second control device 61 is free from occupying the valuable space of the first accommodating cavity 101a in the height direction, and the air fryer 1 is further miniaturized in the height direction.

[0082] It should be noted that the vertical plane is a reference plane perpendicular to the horizontal plane.

[0083] In some embodiments, as shown in FIG. 1, the first hot air assembly 20 is located above the first frying barrel 40 in the height direction of the air fryer 1. Figure 4

[0084] It should be noted that arranging the first hot air assembly 20 above the first frying barrel 40 can make the high-temperature hot air generated by the first hot air assembly 20 directly and uniformly cover the inside of the first cooking cavity 401, and the hot air blown into the first cooking cavity 401 from the top of the first frying barrel 40 can be fully circulated, so as to ensure that the temperature distribution in the first frying barrel 40 is more uniform. Compared with the related art, in which high-temperature hot air is blown into the frying barrel from the side, blowing hot air from the top of the frying barrel can effectively avoid the problem of local overheating or incomplete cooking of food caused by heat concentration, for example, the food near the hot air device is already burnt, but the food far from the hot air device is not cooked, thereby improving the cooking quality and taste of the food. In addition, since the hot air circulates in the first frying barrel 40, the hot air is fully utilized and does not need to flow out of the first cooking cavity 401, unlike the related art in which hot air needs to circulate out of the first frying barrel 40, which will cause the temperature of the outer shell of the air fryer to rise, thereby reducing the use safety of the air fryer.

[0085] The second hot air assembly 30 is arranged above the second frying barrel 50, which has the same technical effect as the first hot air assembly 20 arranged above the first frying barrel 40, and details are not repeated here.

[0086] ​It is worth noting that in the air fryer 1 provided by the embodiments of the present application, the first hot air assembly 20 is arranged above the first frying barrel 40, and the second hot air assembly 30 is also arranged above the second frying barrel 50. The first hot air assembly 20 and the second hot air assembly 30 arranged in this way can not only realize independent heating of the two frying barrels respectively, but also can ensure that the food materials in each frying barrel can be uniformly heated and processed, and the same ideal cooking effect can be obtained, so that the problem of unbalanced cooking caused by the fact that hot air cannot enter the cooking cavity from the top of any frying barrel can be avoided.

[0087] In some embodiments, the air fryer 1 further comprises a first air guide cover arranged in the first containing cavity 101a, the first air guide cover forms a first hot air cavity, the first air guide cover covers the first frying barrel 40, and the first hot air cavity is communicated with the first cooking cavity 401. The side of the first air guide cover away from the first frying barrel 40 forms a first ventilation channel 101b with the shell of the air fryer 1, and the first ventilation channel 101b can be communicated downward with the cavity around the side of the first frying barrel 40.

[0088] In some embodiments, the first fan assembly can include a first motor 202, and the output shaft of the first motor 202 is connected to the first hot air fan 203 through the first air guide cover. The first motor 202 is located in the first ventilation channel 101b, and the first motor 202 includes a stator and a rotor, and the outer circumferential side of the rotor is connected with the first heat dissipation blade 2021 for disturbing air flow. In this way, when the first motor 202 drives the first hot air fan 203 to rotate, the first heat dissipation blade 2021 can also be driven to disturb the air flow, so that the air flow in the first ventilation channel 101b flows quickly, thereby improving the heat dissipation efficiency and improving the safety of the air fryer 1. In addition, by using one first motor 202, hot air can be disturbed to obtain balanced cooking effect, and cold air can also be disturbed to improve the safety of the air fryer 1, thereby simplifying the structure of the air fryer 1.

[0089] In order to reduce the overall height of the air fryer 1, the first motor 202 can be an ultra-thin motor. The first hot air fan 203 can also be an ultra-thin fan to reduce the space occupation of the first motor 202 along the height direction of the first containing cavity 101a.

[0090] In some embodiments, the thickness of the first motor 202 along the height direction of the air fryer 1 is L1, and L1<50mm. In this way, the overall structure of the first hot air assembly 20 is more compact, which further reduces the space occupation of the air fryer 1 in the height direction, and helps to realize the miniaturization and light weight of the air fryer 1. At the same time, the ultra-thin first motor 202 and the first hot air fan 203 not only ensure strong hot air output, but also reduce operating noise, thereby improving the cooking experience of the user.

[0091] Optionally, as Figure 6As shown, the first heating member 201 includes a heating portion 2011 extending along a spiral line. The heating portion 2011 includes heating heat pipes nested with each other and extending along the spiral line. The double-spiral heating portion 2011 can increase the contact area between the heat pipes and the air in a unit area, thereby effectively improving the heating efficiency. On the other hand, the double-spiral heating portion 2011 extending along the spiral line in the same horizontal plane does not cause the height of the first heating member 201 to increase in the height direction, which helps to maintain the compactness of the air fryer 1 structure.

[0092] In some embodiments, as shown, Figure 4 As shown, along the height direction of the air fryer 1, the second hot air assembly 30 is located above the second frying barrel 50.

[0093] Along the height direction, the second hot air assembly 30 can include a second heating member 301 and a second fan assembly, the second heating member 301 being located between the second frying barrel 50 and the second fan assembly, and the second fan assembly being capable of disturbing the airflow, the airflow passing through the high-temperature second heating member 301, the temperature of the airflow being rapidly increased to form high-temperature hot air.

[0094] In some embodiments, the air fryer 1 further includes a second air guide cover arranged in the second accommodating cavity 102a, the second air guide cover forming a second hot air cavity, the second air guide cover covering the second frying barrel 50, and the second hot air cavity being communicated with the second cooking cavity 501. The side of the second air guide cover away from the second frying barrel 50 forms a second ventilation passage 102b with the shell of the air fryer 1, and the second ventilation passage 102b can be downwardly communicated with the cavity around the side of the second frying barrel 50.

[0095] In some embodiments, the second fan assembly can include a second motor 302, and the output shaft of the second motor 302 is connected to a second hot air fan 303 through the second air guide cover. The second motor 302 is located in the second ventilation passage 102b, and the second motor includes a stator and a rotor, and the outer circumferential side of the rotor is connected with second heat dissipation blades 3021 for disturbing the airflow. In this way, when the second motor 302 drives the second hot air fan 303 to rotate, the second heat dissipation blades 3021 can be simultaneously driven to disturb the airflow, so that the airflow in the second ventilation passage 102b flows rapidly, thereby improving the heat dissipation efficiency and enhancing the safety of the air fryer 1.

[0096] In order to reduce the overall height of the air fryer 1, the second motor 302 can be an ultra-thin motor, and the second hot air fan 303 can be an ultra-thin fan, so as to reduce the space occupation of the second fan assembly in the height direction of the second accommodating cavity 102a.

[0097] In some embodiments, the second motor 302 has a thickness L2 in the height direction of the air fryer 1, where L2 < 50 mm. In this way, the overall structure of the first hot air assembly 20 is more compact, further reducing the space occupation of the air fryer 1 in the height direction, which helps to realize the miniaturization and light weight of the air fryer 1. At the same time, the ultra-thin second motor 302 and the second hot air fan 303 not only ensure strong hot air output, but also reduce operating noise, improving the user's cooking experience.

[0098] Optionally, the second heating element 301 includes a heating pipe extending along a spiral line. The spiral heating pipe can increase the contact area between the heating pipe and the air per unit area, thereby effectively improving the heating efficiency. On the other hand, the double spiral heating pipe extending along the spiral line in the same horizontal plane does not increase the height of the second heating element 301 in the height direction, which helps to maintain the compactness of the air fryer 1 structure.

[0099] In some embodiments, in combination with the above-mentioned volume optimization scheme of the air fryer 1, the overall height H1 of the air fryer 1 is less than 410 mm, which significantly improves the space adaptability of the air fryer 1, making the air fryer 1 easily integrate into various kitchen environments, especially for those modern kitchens with limited space, providing greater convenience.

[0100] Specifically, the height H1 of the air fryer 1 can be 405 mm.

[0101] In some embodiments, the air fryer 1 further comprises a heat radiation element 90, which is located in the second containing cavity 102a and is spaced apart from the second hot air assembly 30 in the height direction. The second frying basket 50 is located between the second hot air assembly 30 and the heat radiation element 90.

[0102] Optionally, the heat radiation element 90 can be a heating pipe, an infrared heating element, a ceramic heating element, etc.

[0103] The heat radiation element 90 is arranged in the body 10 and located at the bottom of the second frying basket 50. The arrangement of the heat radiation element 90 not only improves the heating speed of the second hot air assembly 30, but also ensures the uniformity of the heating of the food.

[0104] It can be understood that since the heat radiation element 90 is spaced apart from the second hot air assembly 30 in the height direction, the food can be subjected to the action of hot air and heat radiation at the same time during cooking. The heat radiation element 90 radiates heat energy from the bottom upwards, and the hot air blown from the top by the second hot air assembly 30 forms a full-range heating effect on the food. The food can be subjected to the efficient circulation of hot air and the direct penetration of heat radiation at the same time during cooking, which can not only ensure that the surface of the food forms a crispy taste, but also further avoid the phenomenon of insufficient cooking of the bottom of the food.

[0105] In some embodiments, as shown in Figure 1 , Figure 3 and Figure 5 , the machine 10 comprises a first machine body 101. The first machine body 101 comprises a first accommodating cavity 101a, and the inside of the first machine body 101 is formed with a first ventilation passage 101b which is in communication with the outside. The machine 10 further comprises a second machine body 102. The second machine body 102 comprises a second accommodating cavity 102a, and the inside of the second machine body 102 is formed with a second ventilation passage 102b which is in communication with the outside. The machine 10 further comprises a partition assembly 103. The partition assembly 103 is connected to the first machine body 101 and the second machine body 102, and is located between the first machine body 101 and the second machine body 102. The partition assembly 103 comprises a partition 1031 and a ventilation opening 1032a. The ventilation opening 1032a is in communication with the first ventilation passage 101b and the second ventilation passage 102b.

[0106] The partition assembly 103 comprises the partition 1031. The partition 1031 can have heat insulation performance, so as to prevent heat transfer between the first accommodating cavity 101a and the second accommodating cavity 102a. In addition, the partition 1031 ensures that the first accommodating cavity 101a and the second accommodating cavity 102a are relatively isolated, and the food materials cooked in the first accommodating cavity 101a and the second accommodating cavity 102a will not produce cross smell.

[0107] Optionally, the partition 1031 can be made of high-temperature-resistant and heat-insulating material, such as thermosetting heat-insulating material, so as to ensure the heat insulation performance of the partition 1031 in the high-temperature cooking environment, and the stability and durability of the partition 1031 itself.

[0108] It can be understood that the second hot air assembly 30 is located below the first accommodating cavity 101a. The high-temperature hot air in the first frying barrel 40 will cause the temperature of the first frying barrel 40 to rise, and this high temperature will affect the working performance and service life of the second hot air assembly 30. By arranging the partition assembly 103 between the first accommodating cavity 101a and the second accommodating cavity 102a, the heat insulation performance of the partition 1031 can be used to reduce the high temperature in the first accommodating cavity 101a as much as possible to the second hot air assembly 30, so as to ensure that the second hot air assembly 30 has stable working performance.

[0109] As shown in Figures 3 to 5As shown, the first body 101 comprises a first ventilation channel 101b in communication with the outside, which is used for heat dissipation. It can be understood that the first hot air assembly 20 will generate high temperature during operation, which will be conducted to the outer shell of the air fryer 1, causing the temperature of the outer shell to continuously rise, resulting in the safety problem of scalding the user or aging of the outer shell, and also affecting the working performance of the electrical components in the first accommodating cavity 101a. Therefore, the first body 101 is provided with the first ventilation channel 101b in communication with the outside, so as to quickly dissipate the heat energy (specifically, the space other than the first cooking cavity 401) in the first cooking cavity 401 to the external environment, so as to avoid the above safety problem.

[0110] Since the first accommodating cavity 101a and the second accommodating cavity 102a are separated and independent from each other, the second body 102 is also provided with a second ventilation channel 102b in communication with the outside, so as to quickly dissipate the heat of the second accommodating cavity 102a to the external environment.

[0111] Specifically, the second body 102 comprises a second ventilation channel 102b for heat dissipation. It can be understood that the second hot air assembly 30 will generate high temperature during operation, which will be conducted to the outer shell of the air fryer 1, causing the temperature of the outer shell to continuously rise, resulting in the safety problem of scalding the user or aging of the outer shell. Therefore, the second body 102 is provided with the second ventilation channel 102b in communication with the outside, so as to quickly dissipate the heat energy (specifically, the space other than the second cooking cavity 501) in the second cooking cavity 501 to the external environment, so as to avoid the above safety problem.

[0112] It is worth noting that the air fryer 1 provided by the embodiments of the present application sets the ventilation port 1032a in communication with the first ventilation channel 101b and the second ventilation channel 102b on the partition assembly 103, so that the partition assembly 103 can be used to separate the first accommodating cavity 101a and the second accommodating cavity 102a to avoid cross-odor between food materials, reduce heat transfer between the first accommodating cavity 101a and the second accommodating cavity 102a, and inject cold air into the first ventilation channel 101b and the second ventilation channel 102b to reduce the temperature in the first accommodating cavity 101a and the second accommodating cavity 102a. The partition assembly 103 integrates multiple functions, reduces the number of structural components in the air fryer 1, and further miniaturizes the volume of the air fryer 1.

[0113] In some embodiments, as Figure 7As shown, the first shell 1012 includes a first matching part 10121 protruding or recessed relative to the top of the body 10, the second shell 1022 includes a second matching part 10221 recessed or protruding toward the top of the body 10, and the partition assembly 103 includes a third matching part 1034 adapted to the first matching part 10121 and the second matching part 10221; the first matching part 10121, the third matching part 1034 and the second matching part 10221 are cooperatively installed.

[0114] The first matching part 10121, the second matching part 10221 and the third matching part 1034 can be arranged on the back of the air fryer 1 (the side facing away from the user), so that the front of the air fryer 1 has a good appearance. The first matching part 10121, the second matching part 10221 and the third matching part 1034 can be arranged correspondingly along the height direction of the air fryer 1 to ensure the smooth assembly of the first shell 1012 and the second shell 1022.

[0115] The first matching part 10121 and the second matching part 10221 are recessed and protruded, and the third matching part 1034 is adapted to the shape of the first matching part 10121 and the second matching part 10221. The structure of the recessed and protruded matching between the first matching part 10121 and the second matching part 10221 effectively improves the stability of the connection between the two cooking cavities, and ensures the structural stability and safety of the air fryer 1 during use.

[0116] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
