Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to an air fryer. Background Art

[0002] In the related art, the cooking environment inside the cooking device is a closed environment, and the food is cooked into finished food in the closed environment.

[0003] However, in the actual cooking process, since the internal and external air flows cannot be exchanged, cooking parameters such as humidity and oxygen content in the closed environment cannot be adjusted, resulting in technical defects in the cooking equipment that cannot meet food cooking needs and the quality of finished food is poor. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0005] Therefore, the utility model proposes an air fryer.

[0006] In view of this, the air fryer provided by the utility model includes: a main body; an inner pot, which is arranged in the main body, and the inner pot and the main body enclose a cooking cavity; a grip assembly, which is arranged on the side of the main body, and the grip assembly includes a first air duct, a first end of the first air duct is connected to the cooking cavity, and a second end of the first air duct is connected to the space outside the main body and the grip assembly.

[0007] The present application defines an air fryer, which includes a body and an inner pot, wherein the body is a frame structure of the air fryer, and is used to position, protect and support other working structures on the air fryer. The inner pot is arranged in the body, and the body and the inner pot together enclose a cooking cavity, in which food is placed, and the food is processed into a finished product in the cooking cavity.

[0008] The inner pot can be installed in the main body in a pull-out manner. The air fryer also includes a holding component, which is connected to the inner pot. The user can hold the holding component by hand to perform a pulling action, so as to push the inner pot into the main body through the holding component, or pull the inner pot out of the main body, thereby reducing the difficulty of disassembling and assembling the inner pot and making it convenient for users to store and retrieve food.

[0009] Specifically, a first air duct is formed in the grip assembly, the first end of the first air duct is connected to the cooking cavity, the second end of the first air duct extends toward the outer surface of the grip assembly, and finally communicates with the space outside the body and the grip assembly, wherein the first air duct is at least partially located outside the cooking cavity. During operation, the gas flowing in the cooking cavity forms an internal circulation airflow. Based on the characteristics of the fluid medium, the pressure in the area with a large flow rate is relatively small during the flow of the fluid medium. Due to the existence of the internal circulation airflow, the pressure in the cooking cavity is relatively small compared to the pressure of the external environment of the body. Under the action of the pressure difference, the external gas is pressed into the first air duct, and an external air flow is formed in the first air duct, and the external air flow flows from the second end of the first air duct to the first end of the first air duct. After entering the cooking cavity, the external air flow merges into the internal circulation airflow, so that the cooking cavity can continuously introduce external air during operation. Therefore, the humidity, oxygen content and other cooking parameters in the cooking cavity are adjusted with the help of external air to meet the cooking requirements of specific food, and the technical defects of the related art that the humidity, oxygen content and other cooking parameters cannot be adjusted, the food cooking requirements cannot be met, and the quality of the finished food is poor.

[0010] On this basis, compared with the technical solution of arranging the first air duct in the body, arranging the first air duct in the grip assembly can avoid re-molding and designing the body, thereby reducing the improvement cost of the air fryer. At the same time, when the inner pot and the grip assembly are removed from the body, the first air duct is disconnected from the cooking cavity, which can prevent the oil smoke in the cooking cavity from leaking out through the first air duct when the user cleans the inner pot or stores and takes out food, thereby reducing the pollution of the air fryer to the external environment.

[0011] In addition, the air fryer provided by the utility model may also have the following additional technical features:

[0012] In some technical solutions of the present invention, optionally, the holding assembly includes: a handle; a pipe, which is arranged in the handle, and the pipe encloses a first air duct, and the first end of the first air duct is connected to the air inlet.

[0013] In this technical solution, the grip assembly includes a handle and a pipe. The handle is connected to the inner liner and is located around the inner liner. The user can pull out or push in the inner liner by grabbing the extended handle, thereby providing convenient conditions for disassembly and assembly of the inner liner.

[0014] The duct is arranged inside the handle, and the inner surface of the duct encloses a first air duct, and the air flow introduced from the outside first enters the duct, and then flows into the cooking cavity through the duct. By arranging the duct inside the handle, the idle space in the handle can be reasonably utilized, thereby improving the compactness of the structure of the grip assembly, and further providing convenient conditions for the miniaturization and lightweight design of the grip assembly on the basis of ensuring that the grip assembly can transport the air flow introduced from the outside to the cooking cavity.

[0015] In some technical solutions of the present utility model, optionally, the cross-sectional area of ​​the first air duct at one end close to the air inlet is not less than the cross-sectional area of ​​the end away from the air inlet.

[0016] In this technical solution, the end of the first air duct close to the air inlet is the air outlet end of the first air duct, and the end away from the air inlet is the air inlet end. Under the action of the internal and external pressure difference, the air flow introduced from the outside enters the first air duct from the air inlet end, and finally merges into the cooking cavity from the air outlet end.

[0017] On this basis, the cross-sectional area of ​​the air outlet end of the first air duct is the first cross-sectional area, the cross-sectional area of ​​the air inlet end of the first air duct is the second cross-sectional area, and the first cross-sectional area is greater than or equal to the second cross-sectional area.

[0018] By limiting the cross-sectional area of ​​an air duct close to the air inlet to be no less than the cross-sectional area of ​​the end away from the air inlet, the rate at which air introduced from the outside flows into the air inlet can be limited, thereby preventing the air introduced from the outside with too high a flow rate from generating obvious turbulent noise at the air inlet, thereby achieving the technical effect of improving the practicality of the air fryer and enhancing the user experience.

[0019] In some technical solutions of the utility model, optionally, the main body further includes a shell, a hand groove is formed between the handle and the shell, and the inlet of the pipeline faces away from the hand groove.

[0020] In this technical solution, the handle includes a connecting portion and a gripping portion, wherein the first end of the connecting portion is connected to the outer shell through a cover plate, and the connecting portion extends outwardly along the radial direction of the inner shell. The gripping portion is connected to the second end of the connecting portion, and a gap is left between the gripping portion and the outer shell, and the gap forms a hand groove.

[0021] During the process of pushing and pulling the inner liner, the user holds the hands around the gripping part. By providing the hand groove, the user's hand can be partially placed between the gripping part and the outer shell, which makes it easier for the user to grasp the handle and improves the gripping stability, reducing the possibility of the inner liner falling out of the hand.

[0022] On this basis, the entrance of the pipeline is set on the connecting part. By setting the entrance of the pipeline away from the gripping part, it can be avoided that the user's hand blocks the entrance of the pipeline when grasping the gripping part, ensuring that the air flow introduced from the outside can smoothly enter the first air duct. At the same time, on the connecting part, the entrance of the pipeline faces away from the hand groove below the connecting part. When the user grasps the handle, at least part of the hand groove is filled with the user's hand. Turning the entrance of the pipeline away from the hand groove can also avoid the user's hand blocking the entrance of the pipeline, ensuring that the air flow introduced from the outside can smoothly enter the first air duct. On the other hand, because the first air duct is connected to the cooking cavity, the heat in the cooking cavity is inevitably transferred to the outside through the first air duct. By turning the entrance of the pipeline away from the hand groove, the user can avoid being scalded by the heat discharged from the entrance of the pipeline when extracting the inner pot, thereby achieving the technical effect of improving the safety and reliability of the air fryer.

[0023] In some technical solutions of the utility model, optionally, the main body includes an opening, and the shell further includes: a cover plate, which is located on the peripheral side of the inner container, the cover plate covers the opening, and the handle is connected to the cover plate.

[0024] In this technical solution, an opening is provided on the main body, the size of the opening is larger than the outer contour size of the inner liner, and the inner liner can be inserted into the main body through the opening and can be taken out from the opening.

[0025] On this basis, the shell also includes a cover plate, which is fixed on the periphery of the inner pot. When the inner pot is pushed into the predetermined installation position in the body, the cover plate covers the opening on the body. The handle is fixed on the cover plate. During the assembly process, the cover plate is first assembled to the outside of the body, and then the handle is installed on the cover plate. Among them, an air inlet is provided on the side wall of the inner pot. When the handle is assembled, the pipe is connected to the air inlet to ensure that the air flow introduced from the outside can smoothly flow into the cooking cavity inside the inner pot.

[0026] By setting the cover, on the one hand, the inner pot can be shielded to prevent users from accidentally touching the inner pot and getting burned when pulling it out; on the other hand, the cooperation between the cover and the opening can provide positioning for the inner pot to prevent the inner pot from vibrating frequently or even being misplaced during operation, thereby achieving the technical effect of improving the structural stability and safety of the air fryer.

[0027] In some technical solutions of the present utility model, optionally, the cooking cavity includes a second air duct, and the first end and the second end of the second air duct are both connected to the cooking cavity; the first air duct is connected to the second air duct.

[0028] In this technical solution, the air fryer also includes a second air duct, the first end of the second air duct is connected to the cooking cavity, and the second end of the second air duct is also connected to the cooking cavity, wherein the second air duct is arranged inside the cooking cavity. The first end of the first air duct is connected to the middle section of the second air duct, and the second end of the first air duct is connected to the space outside the body, wherein the first air duct is at least partially located outside the cooking cavity, and when the second air duct is tightly fitted to the inner wall of the cooking cavity, the first air duct is entirely located outside the cooking cavity, and when the second air duct is away from the inner wall of the cooking cavity, the first air duct partially extends into the cooking cavity and is connected to the second air duct, and the rest of the first air duct is located outside the cooking cavity and extends toward the outer surface of the grip assembly. That is, the second air duct connects two different areas in the cooking cavity, and the first air duct connects the cooking cavity and the outside of the air fryer.

[0029] During operation, the gas flowing in the cooking cavity flows into the second air duct from one of the first end and the second end of the second air duct, and finally flows out of the second air duct from the other end of the first end and the second end to form an internal circulation airflow in the second air duct. Based on the characteristics of the fluid medium, the pressure of the area with a large flow rate is relatively small during the flow of the fluid medium. Due to the existence of the internal circulation airflow, the pressure in the second flow channel is relatively small compared to the pressure of the external environment of the body. Under the action of the pressure difference, the external gas is pressed into the first air duct, and an external air flow is formed in the first air duct, and the external air flow flows from the second end of the first air duct to the first end of the first air duct. After entering the second air duct, the external air flow merges into the internal circulation airflow and finally flows into the cooking cavity, so that the cooking cavity can continuously introduce external air during operation. Therefore, the cooking parameters such as humidity and oxygen content in the cooking cavity are adjusted with the help of external air to meet the cooking requirements of specific food, and the technical defects of the related art that the cooking parameters such as humidity and oxygen content cannot be adjusted, the food cooking requirements cannot be met, and the quality of the finished food is poor.

[0030] In some technical solutions of the present invention, optionally, the air fryer also includes: a cooking fan, the cooking fan is used to form an internal circulation of hot air in the cooking cavity, and the extension direction of the second air duct is the same as the direction of the internal circulation of the hot air.

[0031] In this technical solution, a cooking fan is also provided in the air fryer. When the cooking fan is turned on, an internal circulating airflow can be formed in the cooking cavity. On this basis, in combination with a heating component that can generate heat, an internal circulation of hot air can be formed in the cooking cavity. The food placed in the cooking cavity is heated in the internal circulation of hot air to obtain finished food with a crispy surface and golden color.

[0032] Among them, after completing the selection and assembly of the cooking fan, the shape of the hot air internal circulation formed by the cooking fan in the cooking cavity is fixed. On this basis, the extension direction of the second air duct located in the cooking cavity is the same as the direction of the hot air internal circulation in the area where it is located, so as to form a second air duct in the cooking cavity with a shape consistent with the shape of the hot air internal circulation.

[0033] By setting a second air duct whose shape matches the hot air internal circulation, the flow direction of the gas in the second air duct can be made consistent with the flow direction of the hot air internal circulation, thereby reducing the resistance of the gas entering the second air duct and increasing the flow rate of the gas in the second air duct, thereby increasing the air pressure difference between the second air duct and the outside of the air fryer, and increasing the flow rate of the air flow introduced from the outside, thereby achieving the technical effect of increasing the environmental adjustment rate in the cooking cavity and improving the quality of the cooked food.

[0034] In some technical solutions of the utility model, optionally, the air fryer further includes: an air duct plate connected to the inner pot, and the air duct plate and the inner wall of the inner pot enclose a second air duct.

[0035] In this embodiment, the air fryer further comprises an air duct plate, which is arranged in the cooking cavity and connected to the inner wall of the inner pot. After the air duct plate is assembled, the air duct plate and the inner wall of the inner pot together enclose a second air duct. In addition, the air duct plate blocks the air inlet on the inner wall of the inner pot to ensure that the external air flow discharged from the first pipeline can flow into the second air duct.

[0036] By providing the air duct plate, the inner wall of the inner pot can be reasonably utilized, thereby simplifying the structure of the air fryer and reducing the cost of the air fryer. In addition, the assembly can be completed by fixing the air duct plate to the inner wall of the inner pot, eliminating the need for independent positioning and supporting structures, thereby achieving the technical effect of reducing the difficulty of assembling the air fryer.

[0037] In some technical solutions of the present invention, optionally, the air fryer further includes: a fan, which is arranged on a side of the first air duct facing the outside of the grip assembly, and the airflow in the first air duct can drive the fan to rotate.

[0038] In this technical solution, the air fryer further comprises a fan, which is arranged in the first air duct and close to the housing of the grip assembly to ensure that the user can observe the fan. The air flow introduced from the outside into the first air duct can drive the fan to rotate.

[0039] By setting up an observable fan, the externalization effect of the air flow introduced from the outside can be achieved, so that the user can judge whether there is an air flow introduced from the outside by observing whether the fan is rotating, and judge the strength of the air flow introduced from the outside by observing the speed of the fan, providing convenient conditions for the user to control the cooking details of the air fryer.

[0040] In some technical solutions of the utility model, optionally, the fan includes: a cover body, connected to the holding assembly, the cover body covers the port of the second end of the first air duct, the cover body includes a through hole; and fan blades, the fan blades are located inside the cover body, and the fan blades can rotate relative to the cover body.

[0041] In this technical solution, the fan includes a cover body and a fan blade. The cover body is connected to the grip assembly, and the cover body is embedded at the entrance of the first air duct. The fan blade is rotatably connected to the cover body, and the fan blade is located inside the cover body. The cover body can position and protect the fan blade. On the one hand, it ensures that the fan blade can stay in the predetermined working position to prevent the fan blade from colliding with the inner wall of the first air duct, and on the other hand, it can prevent the user from accidentally touching the fan blade.

[0042] Among them, a through hole is arranged on the cover body, and the air flow introduced from the outside can enter the first air duct through the through hole. The user can also observe the fan blades inside the cover body through the through hole.

[0043] In some technical solutions of the utility model, optionally, the fan also includes: an assembly component, on which the fan blades are sleeved; a limiting component, connected to the end of the assembly component facing away from the cover body, and the cover body and the limiting component provide limiting in the axial direction of the fan blades; wherein the cover body is a light-transmitting cover body.

[0044] In this technical solution, the fan also includes an assembly component and a limiting component. The assembly component is columnar, the first end of the assembly component is connected to the lower surface of the cover body, and the limiting component is connected to the second end of the assembly component. The fan blades are sleeved on the assembly component through the shaft hole, and the fan blades rotate on the assembly component under the action of the air flow introduced from the outside. The fan blades are located between the cover body and the limiting component, and the cover body and the limiting component provide limits on the upper and lower sides of the fan blades to prevent the fan blades from moving in the axial direction and ensure the smooth rotation of the fan blades.

[0045] Specifically, the first end of the assembly component is threadedly connected to the cover body, or the first end of the assembly component is snap-fitted to the cover body through a buckle.

[0046] In this technical solution, the cover body is prepared by using a light-transmitting material to prepare a light-transmitting cover body.

[0047] By providing a light-transmitting cover, the user can observe the status of the fan blades inside the cover through the cover, thereby improving the externalization effect of the fan on introducing air flow from the outside and reducing the difficulty for the user to observe the fan blades.

[0048] Specifically, the cover can be made of materials such as glass and plastic.

DETAILED DESCRIPTION

[0060] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0061] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0062] Refer to the following Figures 1 to 7 An air fryer according to some embodiments of the present invention is described.

[0063] like Figure 1 and Figure 2 As shown, one embodiment of the utility model provides an air fryer 100, which includes: a main body 110; an inner pot 120, which is arranged in the main body 110, and the inner pot 120 and the main body 110 enclose a cooking cavity 1102; a grip assembly 130, which is arranged on the side of the main body 110, and the grip assembly 130 includes a first air duct 1302, a first end of the first air duct 1302 is connected to the cooking cavity 1102, and a second end of the first air duct 1302 is connected to the space outside the main body 110 and the grip assembly 130.

[0064] Figure 2In the figure, arrow a shows the internal circulation airflow, and arrow b shows the airflow introduced from the outside.

[0065] The present application defines an air fryer 100, which includes a body 110 and an inner pot 120. The body 110 is a frame structure of the air fryer 100, which is used to position, protect and support other working structures on the air fryer 100. The inner pot 120 is arranged in the body 110, and the body 110 and the inner pot 120 together enclose a cooking cavity 1102, in which food is placed and processed into a finished product.

[0066] Among them, the inner pot 120 can be installed in the main body 110 in a pullable manner. The air fryer 100 also includes a gripping assembly 130, which is connected to the inner pot 120. The user can hold the gripping assembly 130 to perform a pulling action, so as to push the inner pot 120 into the main body 110 through the gripping assembly 130, or pull the inner pot 120 out of the main body 110, thereby reducing the difficulty of disassembling and assembling the inner pot 120 and making it convenient for users to store and retrieve food.

[0067] Specifically, a first air duct 1302 is formed in the grip assembly 130, a first end of the first air duct 1302 is communicated with the cooking cavity 1102, a second end of the first air duct 1302 extends toward the outer surface of the grip assembly 130, and finally communicates with the space outside the body 110 and the grip assembly 130, wherein the first air duct 1302 is at least partially located outside the cooking cavity 1102. During operation, the gas flowing in the cooking cavity 1102 forms an internal circulation airflow. Based on the characteristics of the fluid medium, the pressure of the area with a large flow rate during the flow of the fluid medium is relatively small. Due to the existence of the internal circulation airflow, the pressure in the cooking cavity 1102 is relatively small compared to the pressure of the external environment of the body 110. Under the action of the pressure difference, the external gas is pressed into the first air duct 1302, and an external air flow is formed in the first air duct 1302, and the external air flow flows from the second end of the first air duct 1302 to the first end of the first air duct 1302. The air flow introduced from the outside enters the cooking cavity 1102 and then merges into the internal circulating air flow, so that the cooking cavity 1102 can continuously introduce the outside air during the working process. Thus, the humidity, oxygen content and other cooking parameters in the cooking cavity 1102 are adjusted with the help of the outside air to meet the cooking requirements of specific food, thereby solving the technical defects in the related art that the humidity, oxygen content and other cooking parameters cannot be adjusted, the food cooking requirements cannot be met, and the quality of the finished food is poor.

[0068] On this basis, compared with the embodiment in which the first air duct 1302 is arranged in the body 110, the first air duct 1302 is arranged in the grip assembly 130, which can avoid the need to re-open the mold and design the body 110, thereby reducing the improvement cost of the air fryer 100. At the same time, when the inner pot 120 is removed from the body 110 together with the grip assembly 130, the first air duct 1302 is disconnected from the cooking cavity 1102, which can prevent the oil smoke in the cooking cavity 1102 from leaking out through the first air duct 1302 when the user cleans the inner pot 120 or stores or takes out food, thereby reducing the pollution of the air fryer 100 to the external environment.

[0069] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of the present invention, optionally, the holding assembly 130 includes: a handle 132; a duct 134, which is disposed in the handle 132, and the duct 134 encloses a first air duct 1302, and a first end of the first air duct 1302 is connected to the air inlet.

[0070] In this embodiment, the grip assembly 130 includes a handle 132 and a pipe 134. The handle 132 is connected to the inner liner 120, and the handle 132 is located around the inner liner 120. The user can pull out or push in the inner liner 120 by grabbing the extended handle 132, thereby providing convenient conditions for disassembly and assembly of the inner liner 120.

[0071] The duct 134 is arranged inside the handle 132, and the inner surface of the duct 134 encloses a first air duct 1302. The air flow introduced from the outside first enters the duct 134, and then flows into the cooking cavity 1102 through the duct 134. By arranging the duct 134 inside the handle 132, the idle space in the handle 132 can be reasonably utilized, thereby improving the compactness of the structure of the grip assembly 130, and further providing convenient conditions for the miniaturization and lightweight design of the grip assembly 130 on the basis of ensuring that the grip assembly 130 can transport the air flow introduced from the outside to the cooking cavity 1102.

[0072] In some embodiments, the channel 134 may be a separately provided tube, or may be a tube formed by the inner wall of the gripping assembly 130 .

[0073] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, optionally, the cross-sectional area of ​​the first air duct 1302 at one end close to the air inlet is not less than the cross-sectional area at one end away from the air inlet.

[0074] In this technical solution, the end of the first air duct 1302 close to the air inlet is the air outlet end of the first air duct 1302, and the end away from the air inlet is the air inlet end. Under the action of the internal and external pressure difference, the air flow introduced from the outside enters the first air duct 1302 from the air inlet end, and finally merges into the cooking cavity 1102 from the air outlet end.

[0075] On this basis, the cross-sectional area of ​​the air outlet end of the first air duct 1302 is the first cross-sectional area, the cross-sectional area of ​​the air inlet end of the first air duct 1302 is the second cross-sectional area, and the first cross-sectional area is greater than or equal to the second cross-sectional area.

[0076] By limiting the cross-sectional area of ​​an air duct near the air inlet to be no less than the cross-sectional area of ​​the end far from the air inlet, the rate at which air introduced from the outside flows into the air inlet can be limited, thereby preventing the air introduced from the outside with too high a flow rate from generating obvious turbulent noise at the air inlet, thereby achieving the technical effect of improving the practicality of the air fryer 100 and enhancing the user experience.

[0077] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, optionally, the body 110 further includes a shell, a hand groove 1326 is formed between the handle 132 and the shell, and the entrance of the pipe 134 faces away from the hand groove 1326 .

[0078] In this technical solution, the handle 132 includes a connecting portion 1322 and a gripping portion 1324. The first end of the connecting portion 1322 is connected to the outer shell through a cover plate 136, and the connecting portion 1322 extends outwardly along the radial direction of the liner 120. The gripping portion 1324 is connected to the second end of the connecting portion 1322, and a gap is left between the gripping portion 1324 and the outer shell, and the gap forms a hand groove 1326.

[0079] During the process of pushing and pulling the inner liner 120, the user holds the gripping portion 1324 around, and the hand groove 1326 is provided so that the user's hand can be partially placed between the gripping portion 1324 and the outer shell, which makes it easier for the user to grasp the handle 132 and improves the gripping stability, thereby reducing the possibility of the inner liner 120 falling out of the hand.

[0080] On this basis, the inlet of the duct 134 is arranged on the connection part 1322. By setting the inlet of the duct 134 away from the grip part 1324, it is possible to prevent the user from blocking the inlet of the duct 134 with his hand when grasping the grip part 1324, thereby ensuring that the air flow introduced from the outside can smoothly enter the first air duct 1302. At the same time, on the connection part 1322, the inlet of the duct 134 faces away from the hand groove 1326 below the connection part 1322. When the user grasps the handle 132, at least part of the area of ​​the hand groove 1326 is filled by the user's hand. Turning the inlet of the duct 134 away from the hand groove 1326 can also prevent the user's hand from blocking the inlet of the duct 134, thereby ensuring that the air flow introduced from the outside can smoothly enter the first air duct 1302. On the other hand, since the first air duct 1302 is connected to the cooking cavity 1102, the heat in the cooking cavity 1102 is inevitably transferred outward through the first air duct 1302. By turning the entrance of the pipe 134 away from the hand groove 1326, the user can avoid being scalded by the heat discharged from the entrance of the pipe 134 when extracting the inner pot 120, thereby achieving the technical effect of improving the safety and reliability of the air fryer 100.

[0081] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, optionally, the body 110 includes an opening, and the shell further includes: a cover plate 136 located on the peripheral side of the inner liner 120 , the cover plate 136 covers the opening, and the handle 132 is connected to the cover plate 136 .

[0082] In this embodiment, an opening is provided on the body 110 , and the size of the opening is larger than the outer contour size of the liner 120 . The liner 120 can be inserted into the body 110 through the opening and can be taken out from the opening.

[0083] On this basis, the housing further includes a cover plate 136, which is fixed to the periphery of the inner pot 120. When the inner pot 120 is pushed into the predetermined installation position in the body 110, the cover plate 136 covers the opening on the body 110. The handle 132 is fixed to the cover plate 136. During the assembly process, the cover plate 136 is first assembled to the outside of the body 110, and then the handle 132 is installed on the cover plate 136. Among them, an air inlet is provided on the side wall of the inner pot 120. When the handle 132 is assembled, the duct 134 is connected to the air inlet to ensure that the air flow introduced from the outside can smoothly flow into the cooking cavity 1102 inside the inner pot 120.

[0084] By providing the cover plate 136, on the one hand, the inner pot 120 can be shielded to prevent the user from accidentally touching the inner pot 120 and getting burned when taking out the inner pot 120, and on the other hand, the cooperation between the cover plate 136 and the opening can provide positioning for the inner pot 120 to prevent the inner pot 120 from vibrating frequently or even being misplaced during operation, thereby achieving the technical effect of improving the structural stability and safety of the air fryer 100.

[0085] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, optionally, the cooking cavity 1102 includes a second air duct 1104 , and the first end and the second end of the second air duct 1104 are both connected to the cooking cavity 1102 ; the first air duct 1302 is connected to the second air duct 1104 .

[0086] In this embodiment, the air fryer 100 further includes a second air duct 1104 , a first end of the second air duct 1104 is connected to the cooking cavity 1102 , and a second end of the second air duct 1104 is also connected to the cooking cavity 1102 , wherein the second air duct 1104 is arranged inside the cooking cavity 1102 . The first end of the first air duct 1302 is connected to the middle section of the second air duct 1104, and the second end of the first air duct 1302 is connected to the space outside the body 110, wherein the first air duct 1302 is at least partially located outside the cooking cavity 1102, and when the second air duct 1104 is closely attached to the inner wall of the cooking cavity 1102, the first air duct 1302 is entirely located outside the cooking cavity 1102, and when the second air duct 1104 is away from the inner wall of the cooking cavity 1102, the first air duct 1302 partially extends into the cooking cavity 1102 and is connected to the second air duct 1104, and the rest of the first air duct 1302 is located outside the cooking cavity 1102 and extends toward the outer surface of the grip assembly 130. That is, the second air duct 1104 connects two different areas in the cooking cavity 1102, and the first air duct 1302 connects the cooking cavity 1102 and the outside of the air fryer 100.

[0087] During operation, the gas flowing in the cooking cavity 1102 flows into the second air duct 1104 from one of the first end and the second end of the second air duct 1104, and finally flows out of the second air duct 1104 from the other end of the first end and the second end, so as to form an internal circulation airflow in the second air duct 1104. Based on the characteristics of the fluid medium, the pressure of the area with a large flow rate is relatively small during the flow of the fluid medium. Due to the existence of the internal circulation airflow, the pressure in the second flow channel is relatively small compared with the pressure of the external environment of the body 110. Under the action of the pressure difference, the external gas is pressed into the first air duct 1302, and forms an external air flow in the first air duct 1302, and the external air flow flows from the second end of the first air duct 1302 to the first end of the first air duct 1302. After entering the second air duct 1104, the external air flow merges into the internal circulation airflow, and finally flows into the cooking cavity 1102, so that the cooking cavity 1102 can continuously introduce external air during operation. Thus, cooking parameters such as humidity and oxygen content in the cooking cavity 1102 are adjusted with the help of external air to meet the cooking requirements of specific food, thereby solving the technical defects in the related technology that cooking parameters such as humidity and oxygen content cannot be adjusted, cannot meet food cooking requirements, and have poor quality of finished food.

[0088] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, optionally, the air fryer 100 also includes: a cooking fan 150, the cooking fan 150 is used to form a hot air internal circulation in the cooking cavity 1102, and the extension direction of the second air duct 1104 is the same as the direction of the hot air internal circulation.

[0089] In this technical solution, a cooking fan 150 is also provided in the air fryer 100. When the cooking fan 150 is turned on, an internal circulation airflow can be formed in the cooking cavity 1102. On this basis, in combination with a heating component that can generate heat, an internal circulation of hot air can be formed in the cooking cavity 1102. The food placed in the cooking cavity 1102 is heated in the internal circulation of hot air to obtain a finished food with a crispy skin and golden color.

[0090] Among them, after completing the selection and assembly of the cooking fan 150, the shape of the hot air internal circulation formed by the cooking fan 150 in the cooking cavity 1102 is fixed. On this basis, the extension direction of the second air duct 1104 located in the cooking cavity 1102 is the same as the direction of the hot air internal circulation in the area where it is located, so as to form a second air duct 1104 in the cooking cavity 1102 whose shape is consistent with the shape of the hot air internal circulation.

[0091] By setting a second air duct 1104 whose shape matches the hot air internal circulation, the flow direction of the gas in the second air duct 1104 can be consistent with the flow direction of the hot air internal circulation, thereby reducing the resistance of the gas entering the second air duct 1104 and increasing the flow rate of the gas in the second air duct 1104, thereby increasing the air pressure difference between the second air duct 1104 and the outside of the air fryer 100, and increasing the flow rate of the air flow introduced from the outside, thereby achieving the technical effect of increasing the environmental adjustment rate in the cooking cavity 1102 and improving the quality of the cooked food.

[0092] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, optionally, the air fryer 100 further includes: an air duct plate 122 connected to the inner pot 120 , and the air duct plate 122 and the inner wall of the inner pot 120 enclose a second air duct 1104 .

[0093] In this embodiment, the air fryer 100 further includes an air duct plate 122, which is disposed in the cooking cavity 1102 and connected to the inner wall of the inner pot 120. After the air duct plate 122 is assembled, the air duct plate 122 and the inner wall of the inner pot 120 jointly enclose a second air duct 1104. In addition, the air duct plate 122 blocks the air inlet on the inner wall of the inner pot 120 to ensure that the external air flow discharged from the first pipe 134 can flow into the second air duct 1104.

[0094] By providing the air duct plate 122, the inner wall of the inner pot 120 can be reasonably utilized, thereby simplifying the structure of the air fryer 100 and reducing the cost of the air fryer 100. In addition, the assembly can be completed by fixing the air duct plate 122 to the inner wall of the inner pot 120, eliminating the need for independent positioning and supporting structures, thereby achieving the technical effect of reducing the difficulty of assembling the air fryer 100.

[0095] like Figure 1 and Figure 3 As shown, in some embodiments of the present invention, optionally, the air fryer 100 further includes: a fan 140, which is disposed on a side of the first air duct 1302 facing the outside of the grip assembly 130, and the airflow in the first air duct 1302 can drive the fan 140 to rotate.

[0096] In this embodiment, the air fryer 100 further includes a fan 140, which is disposed in the first air duct 1302 and close to the housing of the grip assembly 130 to ensure that the user can observe the fan 140. The external air flow flowing into the first air duct 1302 can drive the fan 140 to rotate.

[0097] By setting up an observable fan 140, the externalization effect of the air flow introduced from the outside can be achieved, so that the user can judge whether there is an air flow introduced from the outside by observing whether the fan 140 is rotating, and judge the strength of the air flow introduced from the outside by observing the rotation speed of the fan 140, providing convenient conditions for the user to control the cooking details of the air fryer 100.

The fan blade 144 is rotatably connected to the cover 142, and the fan blade 144 is located inside the cover 142. The cover 142 can position and protect the fan blade 144. On the one hand, it ensures that the fan blade 144 can stay in the predetermined working position to prevent the fan blade 144 from colliding with the inner wall of the first air duct 1302, and on the other hand, it can prevent the user from accidentally touching the fan blade 144.

[0100] The cover body 142 is provided with a through hole 1422 , and air flow introduced from the outside can enter the first air duct 1302 through the through hole 1422 . The user can also observe the fan blades 144 on the inner side of the cover body 142 through the through hole 1422 .

[0101] like Figure 3 and Figure 6 As shown, in some embodiments of the present invention, optionally, the fan 140 also includes: an assembly component 146, and the fan blade 144 is sleeved on the assembly component 146; a limiting component 148, which is connected to the end of the assembly component 146 away from the cover body 142, and the cover body 142 and the limiting component 148 provide limitation in the axial direction of the fan blade 144.

[0102] In this embodiment, the fan 140 further includes an assembly component 146 and a limiting component 148. The assembly component 146 is columnar, a first end of the assembly component 146 is connected to the lower surface of the cover 142, and the limiting component 148 is connected to the second end of the assembly component 146. The fan blade 144 is sleeved on the assembly component 146 through an axial hole, and under the action of the air flow introduced from the outside, the fan blade 144 rotates on the assembly component 146. Among them, the fan blade 144 is located between the cover 142 and the limiting component 148, and the cover 142 and the limiting component 148 provide limiting on the upper and lower sides of the fan blade 144 to prevent the fan blade 144 from moving in the axial direction, thereby ensuring the smooth rotation of the fan blade 144.

[0103] Specifically, the first end of the assembly component 146 is threadedly connected to the cover body 142, or the first end of the assembly component 146 is snap-fitted to the cover body 142 through a buckle.

[0105] In this embodiment, the cover 142 is made of a light-transmitting material to produce a light-transmitting cover.

[0106] By providing a light-transmitting cover, the user can observe the status of the fan blades 144 inside the cover 142 through the cover 142, thereby improving the externalization effect of the fan 140 on the air flow introduced from the outside and reducing the difficulty for the user to observe the fan blades 144.

[0107] Specifically, the cover 142 can be made of materials such as glass and plastic.
