DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0030] 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.

[0031] 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 cooking method for users.

[0032] 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 transfer, which not only affects the taste of the food materials, but also reduces the cooking experience.

[0033] Therefore, some air fryers in the related art are configured with multiple accommodation cavities, and each accommodation cavity is configured with a frying barrel to avoid flavor transfer or adhesion between different food materials. However, the hot air fan in the lower accommodation cavity is usually arranged at the side of the frying barrel, which causes uneven cooking of the food materials in the lower frying barrel.

[0034] Therefore, how to ensure balanced cooking effect of food materials while improving the cooking efficiency of air fryers and preventing flavor transfer and adhesion of food materials has become a problem to be solved in the field of air fryer technology.

[0035] Please refer to Figures 1 to 4 The air fryer 1 provided by the embodiments of the present application includes a shell 10 and a partition plate 101 arranged in the shell 10. The partition plate 101 can separate the internal space of the air fryer 1 into a relatively independent second accommodation cavity 10a and a first accommodation cavity 10b, that is, the airflow in the second accommodation cavity 10a and the first accommodation cavity 10b is not communicated. The second accommodation cavity 10a and the first accommodation cavity 10b are respectively used to accommodate a second frying barrel 40 and a first frying barrel 50.

[0036] The air fryer 1 can include a height direction and a width direction, the height direction is generally perpendicular or close to perpendicular to the width direction. The width direction is the direction of the air fryer 1 towards the user. As shown, the height direction is the Y direction, and the width direction is the X direction. It is worth noting that in the kitchen environment using the air fryer 1, the vertical space is often more easily fully utilized than the horizontal space. The second accommodating cavity 10a and the first accommodating cavity 10b are arranged along the height direction, which can better utilize the vertical space of the kitchen without increasing the area occupied by the table surface of the air fryer 1. Compared with the way of arranging the second accommodating cavity 10a and the first accommodating cavity 10b along the height direction, the second accommodating cavity 10a and the first accommodating cavity 10b arranged along the height direction can save the table surface space in the environment using the air fryer 1, and is more friendly to improve the space utilization of the kitchen environment. Figure 1

[0037] The second accommodating cavity 10a and the first accommodating cavity 10b are arranged along the height direction of the air fryer 1, and the first accommodating cavity 10b is located below the second accommodating cavity 10a.

[0038] It should be noted that the partition plate 101 can not only be used to separate the second accommodating cavity 10a and the first accommodating cavity 10b, but also can have heat insulation performance.

[0039] In some embodiments, the partition plate 101 can be made of high-temperature-resistant and heat-insulating materials, such as thermosetting heat-insulating materials, to ensure that the partition plate 101 has heat insulation performance in a high-temperature cooking environment. In this way, the partition plate 101 can reduce the heat transfer between the second accommodating cavity 10a and the first accommodating cavity 10b, so that each accommodating cavity can work in a set temperature environment.

[0040] As shown, the first accommodating cavity 10b is further provided with a first air guide cover 110. The first air guide cover 110 includes a first hot air cavity 110a for circulating hot air flow. In this way, hot air can flow in the first hot air cavity 110a and is prevented from flowing out of the first hot air cavity 110a, thereby reducing the cooking efficiency of the air fryer 1. Figure 2 As shown, the first frying barrel 50 is removably arranged in the first accommodating cavity 10b, and the first frying barrel 50 includes a first cooking cavity 501 open to the second accommodating cavity 10a, so that the user can take food materials from the first frying barrel 50 through the opening.

[0041] Figure 3 As shown, the first accommodating cavity 10b is further provided with a first air guide cover 110. The first air guide cover 110 includes a first hot air cavity 110a for circulating hot air flow. In this way, hot air can flow in the first hot air cavity 110a and is prevented from flowing out of the first hot air cavity 110a, thereby reducing the cooking efficiency of the air fryer 1.

[0042] As shown, the first accommodating cavity 10b is further provided with a first air guide cover 110. The first air guide cover 110 includes a first hot air cavity 110a for circulating hot air flow. In this way, hot air can flow in the first hot air cavity 110a and is prevented from flowing out of the first hot air cavity 110a, thereby reducing the cooking efficiency of the air fryer 1. Figure 2 ​​As shown, after the first frying barrel 50 is placed in the first accommodating cavity 10b, the first air guide cover 110 is arranged at the opening of the first frying barrel 50 in the height direction, so that the first hot air cavity 110a and the first accommodating cavity 10b are oppositely arranged in the height direction, that is, the hot air can be blown into the first cooking cavity 501 from the top of the first frying barrel 50, and the hot air circulation can be formed in the inside of the first cooking cavity 501.

[0043] Compared with the way of blowing high-temperature hot air into the frying barrel from the side in some air fryers in the related art, the air fryer 1 in the embodiments of the present application can blow hot air from the top of the first frying barrel 50, which can effectively avoid the problem of local overheating or local undercooking of food caused by the concentration of heat energy, for example, the food near the hot air device is already scorched, but the food away from the hot air device is not cooked through, thereby improving the cooking quality and taste of the food.

[0044] Meanwhile, in the way of blowing high-temperature hot air into the frying barrel from the side in the related art, a part of the hot air needs to be circulated to the outside of the frying barrel to form hot air circulation, thereby increasing the risk of high temperature of the shell and reducing the use safety of the air fryer. In the embodiments of the present application, the hot air circulates in the first cooking cavity 501, thereby reducing the heat radiation to the shell of the air fryer 1, and further ensuring the use safety of the air fryer 1.

[0045] In this way, the air fryer 1 in the embodiments of the present application includes the first accommodating cavity 10b and the second accommodating cavity 10a which are separated from each other and are used for accommodating the frying barrel respectively. The airflow in the first accommodating cavity 10b and the second accommodating cavity 10a is not communicated, which can ensure that different kinds of food are cooked in the air fryer 1 in one cooking process, and avoid the problem of odor mixing or adhesion between different foods. Meanwhile, in the first accommodating cavity 10b located below, the first air guide cover 110 is located above the first frying barrel 50, so that the hot air in the first hot air cavity 110a can enter the first cooking cavity 501 of the first frying barrel 50 from the top of the first frying barrel 50, so that the food in the first frying barrel 50 can be evenly cooked, and the phenomenon of local scorching or local undercooking of the food is reduced, thereby avoiding the problem of uneven cooking caused by the hot air entering the frying barrel from the side in the related art.

[0046] In some embodiments, as shown in Figure 2 The air fryer 1 further includes a first hot air fan 303. The first hot air fan 303 is arranged in the first accommodating cavity 10b, and is used for disturbing the hot air to make the hot air flow in a circulating manner, so that the high-temperature hot air acts on the food to make the food have the cooking effect of being fried.

[0047] In some embodiments, the air fryer 1 further comprises a first heating element 302. The first heating element 302 is arranged in the first hot air cavity 110a and is located between the first hot air fan 303 and the first basket 50 along the height direction of the air fryer 1.

[0048] The first hot air fan 303, the first heating element 302 and the first basket 50 are arranged in sequence along the height direction of the air fryer 1, and the first cooking cavity 501 of the first basket 50 is open towards the first heating element 302.

[0049] In this way, the first hot air fan 303 can blow the heat energy generated by the first heating element 302 into the first cooking cavity 501 of the first basket 50 from top to bottom, maximizing the use of the heat energy generated by the first heating element 302, and the heat energy can be blown into the first cooking cavity 501 without being dissipated to the outside of the first air guide cover 110 and the first cooking cavity 501, thereby improving the utilization efficiency of the hot air.

[0050] In some embodiments, the air fryer 1 can comprise a second heating element 202, a second hot air fan 203 and a second basket 40. The second hot air fan 203 is arranged opposite to the second basket 40 along the height direction.

[0051] The second heating element 202 is located above the second hot air fan 203 along the height direction, so that the heat energy generated by the second heating element 202 can be quickly and uniformly distributed in the second cooking cavity of the second basket 40 through the airflow disturbed by the second hot air fan 203, which helps to evenly cook the food.

[0052] In some embodiments, the second heating element 202 can be a heat pipe, a microwave heating element or an infrared heating element, etc.

[0053] It should be noted that, as shown in Figure 3 The second heating element 202 and the second hot air fan 203 are arranged above the second basket 40, so that the high-temperature hot air generated by the second heating element 202 and the second hot air fan 203 can directly and uniformly cover the inside of the second cooking cavity, and the hot air blown into the second cooking cavity from the top of the second basket 40 can be fully circulated, ensuring that the temperature distribution in the second basket 40 is more uniform.

[0054] Compared with the way of blowing high-temperature hot air into the frying barrel from the side in some air fryers in the related art, 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 side is already burnt, but the food away from the hot air device side is not cooked through, thereby improving the cooking quality and taste of the food. It is worth noting that in the air fryer 1 provided by the embodiments of the present application, the second heating element 202 and the second hot air fan 203 are arranged above the second frying barrel 40, and the first hot air fan 303 and the first heating element 302 are also arranged above the first frying barrel 50. Not only can the two frying barrels be heated independently, but also the hot air in each frying barrel can enter the cooking cavity from the top of the frying barrel. The food in each frying barrel can be uniformly heated, and the same ideal cooking effect can be achieved. The problem of uneven cooking of the air fryer 1 caused by the fact that the hot air cannot enter the cooking cavity from the top can be avoided.

[0055] Therefore, in the air fryer 1 provided by the embodiments of the present application, the second heating element 202 and the second hot air fan 203 are arranged above the second frying barrel 40, and the first hot air fan 303 and the first heating element 302 are also arranged above the first frying barrel 50. The food in the two frying barrels can be uniformly cooked. When the user cooks food in any one of the frying barrels, the phenomenon of local burning or incomplete cooking of the food can be reduced, and the overall cooking uniformity of the air fryer 1 is improved.

[0056] In some embodiments, as shown in FIG. 1, the air fryer 1 further includes a first outer shell 104 and a second outer shell 103, and the partition plate 101 is connected to the first outer shell 104 and the second outer shell 103, respectively. Figures 1 to 3 In some embodiments, the second accommodating cavity 10a and the first accommodating cavity 10b each include an opening facing forward, i.e., facing the user, to facilitate the user to conveniently take out the second frying barrel 40 and the first frying barrel 50.

[0057] In some embodiments, the partition plate 101 abuts against the first outer shell 104 or the second outer shell 103. That is, the edge of the partition plate 101 is attached to the first outer shell 104, and the edge of the partition plate 101 can be directly attached to the first outer shell 104 and the second outer shell 103. The partition plate 101 can also be attached to the first outer shell 104 by other structural members and attached to the second outer shell 103 by other structural members.

[0058] Therefore, the second accommodating cavity 10a and the first accommodating cavity 10b separated by the partition plate 101 can not be in communication with each other, reducing the air flow between the second accommodating cavity 10a and the first accommodating cavity 10b, and further reducing the phenomenon of flavor mixing between the food cooked in the second frying barrel 40 and the food cooked in the first frying barrel 50.

[0059] In some embodiments, the partition 101 is sealingly connected with the second housing 103, so that the hot air in the second accommodating cavity 10a is kept in the second accommodating cavity 10a, to further avoid the cross smell caused by the communication between the second accommodating cavity 10a and the first accommodating cavity 10b.

[0060] Specifically, a sealing member can be arranged at the connection between the partition 101 and the second housing 103, to further isolate the second accommodating cavity 10a and the first accommodating cavity 10b.

[0061] In some embodiments, the partition 101 is sealingly connected with the first housing 104, so that the hot air in the first accommodating cavity 10b is kept in the first accommodating cavity 10b, to further avoid the cross smell caused by the communication between the first accommodating cavity 10b and the second accommodating cavity 10a.

[0062] Specifically, a sealing member can be arranged at the connection between the partition 101 and the first housing 104, to further isolate the first accommodating cavity 10b and the second accommodating cavity 10a.

[0063] In some embodiments, the partition 101 can be configured to have a hollow cavity, which can be filled with a heat insulation medium.

[0064] In some embodiments, the hollow cavity can be filled with a heat insulation medium, which can be made of a heat insulation material such as glass fiber, calcium silicate, ceramic fiber, etc., to make the partition 101 have better heat insulation performance.

[0065] In some embodiments, the partition 101 can be configured to have a hollow cavity, which can be a vacuum cavity.

[0066] In some embodiments, the partition 101 can be made of stainless steel. Stainless steel has good ductility and anti-deformation ability, so as to meet the process requirements of vacuumizing the partition 101 and ensure the structural stability of the partition 101.

[0067] Specifically, the hollow cavity can be vacuumized during the manufacturing process of the partition 101. Since vacuum greatly reduces the occurrence of heat conduction, the partition 101 with a vacuum cavity has better heat insulation performance.

[0068] In addition, the vacuum cavity can also reduce the overall weight of the partition 101, so that the air fryer 1 is more lightweight.

[0069] Therefore, due to the heat insulation medium or the vacuum cavity in the partition plate 101, the partition plate 101 has good heat insulation performance, and even if the first hot air fan 303 is located below the second frying barrel 40, the partition plate 101 can reduce the heat radiation of the second frying barrel 40 to the first hot air fan 303 as much as possible, so that the first hot air fan 303 has good working performance and service life.

[0070] In some embodiments, as shown in Figure 1 The air fryer 1 further includes a base 112. The bottom of the base 112 is provided with a first air inlet 112a which is in communication with the external environment, and the base 112 is connected to the first shell 104.

[0071] In some embodiments, as shown in Figure 3 The air fryer 1 further includes a first inner shell 113. The first inner shell 113 is located inside the first shell 104 and is used to accommodate the first frying barrel 50; the side of the first inner shell 113 away from the first frying barrel 50 forms a first heat dissipation channel 115 in communication with the external environment with the first shell 104. The first shell 104 is an appearance part of the air fryer 1, and the first inner shell 113 is arranged inside the first shell 104 and is used to enclose a space for placing the first frying barrel 50. The first shell 104 and the first inner shell 113 have a spacing to form the first heat dissipation channel 115 described above, and the first heat dissipation channel 115 surrounds the peripheral side of the first frying barrel 50.

[0072] Since the first cooking cavity 501 of the first frying barrel 50 circulates hot air, the temperature of the first frying barrel 50 is relatively high. The first heat dissipation channel 115 arranged around the first frying barrel 50 can timely discharge the hot air around the first frying barrel 50 through the first heat dissipation channel 115 to the air fryer 1, preventing more heat energy from being radiated to the first shell 104, thereby improving the use safety of the air fryer 1.

[0073] As shown in Figure 2 The first air guide cover 110 covers the first heating element 302 and the first hot air fan 303. That is, the first air guide cover 110 isolates the first heating element 302 which generates heat and the first hot air fan 303 which disturbs the airflow, and the space in the first air guide cover 110a is in communication with the first cooking cavity 501 so that as much hot air as possible enters the first cooking cavity 501.

[0074] In some embodiments, the side of the first air guide cover 110 away from the first hot air cavity 110a encloses a second heat dissipation channel 116 with the partition plate 101 and the first shell 104. The second heat dissipation channel 116 is in communication with the first heat dissipation channel 115.

[0075] In some embodiments, the first air inlet 112a is connected to the first heat dissipation channel 115 or the second heat dissipation channel 116, that is, external cold air can enter the first heat dissipation channel 115 through the first air inlet 112a or the second heat dissipation channel 116 through the first air inlet 112a.

[0076] In some embodiments, a vent can be provided on the outer periphery of the first air guide shroud 110. The vent is not connected to the first hot air chamber 110a. The second heat dissipation channel 116 can be connected to the first heat dissipation channel 115 located on the periphery of the first frying barrel 50 through the vent.

[0077] like Figure 2 As shown, the cold air entering the first heat dissipation channel 115 from the first air inlet 112a flows from bottom to top and then enters the second heat dissipation channel 116. In this way, the hot air in the first heat dissipation channel 115 and the hot air located outside the first hot air cavity 110a and subjected to heat radiation from the first heating element 302 can be simultaneously dissipated from the air fryer 1 through the second heat dissipation channel 116, so as to prevent the temperature of the first outer shell 104 from rising to a temperature that could easily burn the user, thus ensuring the safety of using the air fryer 1.

[0078] In some embodiments, such as Figure 4 As shown, the air fryer 1 also includes: a first air outlet 106 disposed on the first outer shell 104, and the first air outlet 106 being connected to the second heat dissipation channel 116.

[0079] In this way, the hot air in the first heat dissipation channel 115 and the hot air in the second heat dissipation channel 116 can be simultaneously dissipated from the air fryer 1 through the first air outlet 106, ensuring the heat dissipation efficiency of the air fryer 1.

[0080] like Figure 2 As shown, the air fryer 1 also includes a first heat insulation cover 109. The first heat insulation cover 109 can be constructed as a cover body and disposed within the second heat dissipation channel 116.

[0081] In some embodiments, such as Figure 2 As shown, the air fryer 1 has a first driving component 301. The first driving component 301 is connected to the first hot air fan 303 to drive the first hot air fan 303 to agitate the airflow, causing hot air to circulate within the first cooking chamber 501.

[0082] In some embodiments, the first drive member 301 can be an ultra-thin fan, and the thickness of the first drive member 301 along the height direction can be <50mm. In this way, even if the first drive member 301 is disposed in the first receiving cavity 10b, it will not occupy too much space along the height direction of the air fryer 1, so that the air fryer 1 can be miniaturized and will not occupy too much height space in the kitchen environment.

[0083] In some embodiments, the first driving element 301 may be a drive motor.

[0084] like Figure 2 As shown, the air fryer 1 also includes a first heat insulation cover 109. The first heat insulation cover 109 is disposed outside the first air guide cover 110 and is located between the partition 101 and the first air guide cover 110. The first heat insulation cover 109 can further reduce the heat generated by the first heating element 302 radiating outward to the first outer shell 104 of the air fryer.

[0085] The first driving component 301 can be disposed in the first heat insulation cover 109. The first heat insulation cover 109 is located inside the second heat dissipation channel 116, so the first driving component 301 is also located inside the second heat dissipation channel 116.

[0086] like Figure 2 As shown, the air fryer 1 also includes a first heat dissipation fan blade 70. The first heat dissipation fan blade 70 is connected to the rotor of the first drive member 301. The first drive member 301 can simultaneously drive the first hot air fan 303 to rotate and the first heat dissipation fan blade 70 to rotate, so as to save the number of drive members.

[0087] like Figure 2 As shown, the first heat dissipation fan blade 70 and the first drive member 301 are located in the space formed between the first air guide shroud 110 and the first heat insulation shroud 109. The first heat insulation shroud 109 isolates the first air guide shroud 110 and the first outer shell 104 to reduce the large amount of heat radiation generated by the first heating member 302 from the first outer shell 104.

[0088] The first heat insulation cover 109 can have an open opening facing the first air outlet 106. The first air outlet 106 disposed on the first outer shell 104 can correspond to the opening, so that the first air outlet 106 is connected to the internal space of the first heat insulation cover 109, thereby connecting with the second heat dissipation channel 116.

[0089] By positioning the first air outlet 106 on the first outer casing 104 corresponding to the second heat dissipation channel 116, the air that has undergone heat exchange in the second heat dissipation channel 116 can be directly and quickly discharged from the second heat dissipation channel 116, thereby ensuring the rapid heat dissipation efficiency of the second heat dissipation channel 116.

[0090] like Figure 2As shown, the space between the first heat shield 109 and the first shell 104, and the space between the first heat shield 109 and the first air baffle 110 form the second heat dissipation channel 116. When the first driving member 301 drives the first heat dissipation fan blade 70 to rotate, a negative pressure is formed in the second heat dissipation channel 116, and the cold air entering from the first air inlet 112a can flow upwards through the first heat dissipation channel 115, enter the space between the first heat shield 109 and the first shell 104 through the first through hole 109a, and then enter the space between the first heat shield 109 and the first air baffle 110, and then be discharged from the first shell 104.

[0091] In this way, the second heat dissipation channel 116 can be used not only for dissipating heat from the first driving member 301 to ensure the working performance of the first driving member 301, but also for dissipating heat from the space between the first heat shield 109 and the first shell 104 in a timely manner to reduce the surface temperature of the first shell 104. In some embodiments, as shown in Figure 1 、 Figure 2 and Figure 3 , the air fryer 1 further comprises a top cover 111 connected to the top of the second shell 103, and the air fryer 1 further comprises: a second air inlet 111a provided on the top cover 111 and located at the connection between the second shell 103 and the top cover 111.

[0092] In some embodiments, as shown in Figure 2 , the top cover 111 comprises: a cover body 1111; and a decorative ring 1112 surrounding the cover body 1111, the outer edge of the decorative ring 1112 being closer to the center of the cover body 1111 than the outer edge of the cover body 1111; and a plurality of second air inlets 111a are arranged at intervals on the decorative ring 1112.

[0093] As shown in Figure 3 , the cover body 1111 can be an appearance piece, and the cover body 1111 is located at the top of the entire air fryer 1. The inner side of the cover body 1111, i.e., the side facing the second containing cavity 10a, is provided with the decorative ring 1112 connected to the second shell 103, and the decorative ring 1112 is configured in a ring shape to improve the connection stability between the second shell 103 and the decorative ring 1112.

[0094] As shown in Figure 3 , the outer edge of the decorative ring 1112 is closer to the center of the cover body 1111 than the outer edge of the cover body 1111, i.e., the decorative ring 1112 is recessed in appearance from the cover body 1111. By arranging the second air inlets 111a on the decorative ring 1112, the air inlets can be invisible in appearance, and the second air inlets 111a have a stealth effect, so that the top cover 111 has a design appearance that is integrated as a whole.

[0095] In some embodiments, such as Figure 3 As shown, the air fryer 1 also includes a second air guide shroud 108. The second air guide shroud 108 is disposed on the second outer shell 103 and includes a second hot air chamber 108a. The second heating element 202 and the second hot air fan 203 are located within the second hot air chamber 108a. That is, the second air guide shroud 108 isolates the heat-generating second heating element 202 and the air-dampening second hot air fan 203. The second hot air chamber 108a communicates with the second cooking chamber 401 to allow hot air to enter the second cooking chamber.

[0096] The second air guide shroud 108 is located away from the second heating element 202 and the second hot air fan 203, and forms a third heat dissipation channel 114 between it and the top cover 111 of the second outer shell 103. The third heat dissipation channel 114 is connected to the second air inlet 111a.

[0097] In some embodiments, such as Figure 4 As shown, the air fryer 1 also includes a second air outlet 105, which is disposed on the second outer shell 103 and is connected to the third heat dissipation channel 114 so that the third heat dissipation channel 114 is connected to the outside.

[0098] Thus, the third heat dissipation channel 114, which is isolated from the second heating element 202, is connected to the outside. In this way, the air located outside the second hot air cavity 108a and subjected to the heat radiation of the second heating element 202 can be dissipated from the air fryer 1 in a timely manner through the third heat dissipation channel 114, so as to avoid the temperature of the second outer shell 103 rising to a temperature that could easily burn the user, thereby ensuring the safety of using the air fryer 1.

[0099] In some embodiments, such as Figure 2 As shown, the air fryer 1 also includes a second heat dissipation fan 60 and a second drive unit 201. The second heat dissipation fan 60 is disposed on the outer periphery of the rotor of the second drive unit. The second drive unit 201 can simultaneously drive the second hot air fan 203 to rotate and the second heat dissipation fan 60 to rotate.

[0100] like Figure 2 As shown, the air fryer 1 also includes a second heat insulation cover 107. The second heat insulation cover 107 is constructed as a cover body and is disposed inside the second outer shell 103. The second heat insulation cover 107 covers the outside of the second air guide cover 108, and the second heat dissipation fan 60 and the second drive member 201 are located in the space formed between the second air guide cover 108 and the second heat insulation cover 107. The second heat insulation cover 107 isolates the second heating element 202 and the second outer shell 103 to reduce the large amount of heat radiation generated by the second heating element 202 from the second outer shell 103.

[0101] When the second driving member 201 drives the second heat dissipation fan blade 60 to rotate, cold air enters the space between the second heat shield 107 and the second housing 103 from the second air inlet 111a. Based on the disturbance of the second heat dissipation fan blade 60 to the airflow, the cold air continues to flow into the space between the second heat shield 107 and the second air baffle 108 through the second through hole 107a on the second heat shield 107 to pass through the second driving member 201 and then be discharged into the third heat dissipation channel 114, so as to discharge the heat in the third heat dissipation channel 114 out of the second housing 103, thereby further ensuring that the second housing 103 is within a suitable temperature range, and the use safety of the air fryer 1.

[0102] The second heat shield 107 can have an open opening facing the second air outlet 105, and the second air outlet 105 of the second housing can correspond to the opening, so that the second air outlet 105 communicates with the inner space of the second heat shield 107, thereby communicating the external environment with the third heat dissipation channel 114.

[0103] It is worth noting that, since the second air outlet 105 corresponds to and communicates with the opening of the second heat shield 107, the air in the third heat dissipation channel 114 after heat exchange can be directly and quickly discharged from the third heat dissipation channel 114, so as to ensure the heat dissipation efficiency in the third heat dissipation channel 114.

[0104] In some embodiments, as shown in Figure 4 The first housing 104 includes a first matching part 1041 protruding or recessed relative to the top of the air fryer 1, the second housing 103 includes a second matching part 1031 recessed or protruding toward the top of the air fryer 1, and the partition plate 101 assembly includes a third matching part 1011 adapted to the second matching part 1031 and the first matching part 1041; the second matching part 1031, the third matching part 1011 and the first matching part 1041 are matched and installed.

[0105] The second matching part 1031, the first matching part 1041 and the third matching part 1011 can be arranged on the back of the air fryer 1 (the side facing away from the user), so as to ensure that the front of the air fryer 1 has a good appearance. The second matching part 1031, the first matching part 1041 and the third matching part 1011 can be correspondingly arranged along the height direction of the air fryer 1, so as to ensure the smooth assembly of the first housing 104 and the second housing 103.

[0106] The second fitting part 1031 and the first fitting part 1041 are in concave-convex fitting, and the third fitting part 1011 is adapted to the shape of the second fitting part 1031 and the first fitting part 1041. The structure of the concave-convex fitting between the second fitting part 1031 and the first fitting part 1041 effectively improves the stability of the connection between the first shell 104 and the second shell 103, and guarantees the structural stability and safety of the air fryer 1 during use.
