Description
Technical Field
[0001] The utility model relates to the technical field of cooking appliances, in particular to an air fryer. Background Art
[0002] An air fryer is a fryer that uses rapidly circulating hot air to heat food ingredients, so that the cooked food ingredients achieve the effect and taste of deep-fried food ingredients. One of the main components of an air fryer is a heating component, which is responsible for emitting heat, transmitting the heat to the food through the air, and heating the food. In this process, it is necessary to control the heating temperature: on the one hand, adjust the working temperature of the product, and on the other hand, automatically control the temperature. When the maximum limit of the working temperature is reached, the heating element is controlled to stop working, and when the temperature is lower than the minimum limit of the working temperature, the heating element is turned on for heating.
[0003] For example, the Chinese utility model patent application with the application number CN202122175431.X (the authorized publication number is: CN215937122U) discloses a multifunctional air fryer, which includes a pot cover and a pot body pivotally connected to the pot cover. A hot air component is provided inside the pot cover. The pot body includes an inner pot and an outer pot. A heat conduction component and a temperature sensing element are provided between the inner pot and the outer pot. The temperature sensing element is electrically connected to the heat conduction component. The heat conduction component is used to heat the inner pot when the pot cover and the pot body are opened or closed; wherein, when the inner pot is placed inside the outer pot, the temperature sensing element is used to connect the heat conduction component and to detect the temperature of the inner pot; when the inner pot is removed from the outer pot, the temperature sensing element is used to cut off the heat conduction component.
[0004] There are still certain deficiencies in the air fryer in the above-mentioned patent application. The temperature sensing device of this air fryer is generally arranged at the bottom of the pot body. When there is a problem with the temperature control adjustment of the air fryer and it needs to be repaired, it is necessary to disassemble components such as the outer shell of the pot body to expose the temperature sensing device for detection or replacement. This makes the repair process of the air fryer very cumbersome and reduces the efficiency of after-sales maintenance. On the other hand, even if the components of the air fryer are successfully disassembled and repaired, if some components are not correctly installed or connected during reinstallation, it may cause the air fryer to malfunction or pose a safety hazard.
[0005] Therefore, the existing air fryer still needs to be further improved. Summary of the Utility Model
[0006] The technical problem to be solved by the utility model is to provide an air fryer that can effectively simplify the disassembly and assembly process of the temperature sensing device and improve the maintenance efficiency in view of the current situation of the prior art.
[0007] The technical solution adopted by the utility model to solve the above technical problems is as follows:
[0008] An air fryer, comprising:
[0009] The lower pot assembly includes a lower pot body with an open top and a first heating element for heating the lower pot body;
[0010] The upper cover assembly is provided on the open top of the lower pot body;
[0011] An installation seat is further provided on the side wall of the lower pot body. A vertically extending installation channel is defined on the installation seat or between the installation seat and the lower pot body. The air fryer further includes a temperature sensing component detachably installed in the installation channel. The temperature sensing component includes a fixed shell and a temperature sensing rod provided at the bottom of the fixed shell. In a state where the fixed shell is installed in place in the installation channel, the temperature sensing end of the temperature sensing rod is in direct or indirect contact with the lower pot body or the temperature sensing end of the temperature sensing rod is disposed adjacent to the lower pot body.
[0012] "Indirect contact" between the temperature sensing end of the temperature sensing rod and the lower pot body can be understood as that the temperature sensing end of the temperature sensing rod transfers heat through contact with an additional third component between the temperature sensing end of the temperature sensing rod and the lower pot body, such as through a heat conducting member attached to the outer wall of the lower pot body.
[0013] The temperature sensing end of the temperature sensing rod being "adjacent" to the lower pot body can be understood as that the temperature sensing end of the temperature sensing rod does not contact the lower pot body but is close to the wall of the lower pot body.
[0014] "Vertical" in the above-mentioned "vertically extending installation channel" is not limited to the vertical extension direction, and it can have a certain inclination angle relative to the vertical direction (such as an inclination angle less than 30°).
[0015] For the more convenient up-and-down disassembly and assembly usage habits of users, the top of the installation seat has an installation opening communicating with the installation channel for the temperature sensing component to be loaded into the installation channel from top to bottom, and the temperature sensing rod extends downward from the bottom of the fixed shell.
[0016] To make the disassembly and assembly process of the temperature sensing component more labor-saving, a notch laterally penetrating into the installation channel is further provided on the outer side wall of the installation seat adjacent to the position where the installation opening is located. A convex platform protruding outward is further provided on the side wall of the fixed shell, and an inwardly concave groove is provided on the convex platform as a handle part. In a state where the fixed shell is installed in place in the installation channel, the convex platform is received in the notch of the installation seat.
[0017] To ensure the reliable installation and fixation between the fixed shell and the lower pot assembly, a positioning convex part is provided on one of the inner side wall of the installation channel and the outer side wall of the fixed shell, and a positioning concave part for the positioning convex part to be inserted therein is provided on the other. The above-mentioned positioning convex part can be a convex point, convex rib or other structures protruding from the surface of the corresponding object, and the positioning concave part can be a corresponding concave pit or groove structure.
[0018] In order to further ensure that the disassembly and assembly process of the fixed shell is more labor-saving and easy to operate, an elastically deformable sheet extending vertically is installed on the side wall of the lower pot body. The mounting seat is installed at the position of the elastically deformable sheet on the side wall of the lower pot body. The elastically deformable sheet and the mounting seat define the installation channel, that is, the elastically deformable sheet constitutes a part of the inner side wall of the installation channel. A positioning convex portion protruding towards the installation channel is provided on the side of the elastically deformable sheet facing the installation channel, and a corresponding positioning concave portion is provided on the outer side wall of the fixed shell.
[0019] To facilitate the user to pick up and place food, the lower pot body is generally in a bowl-like structure. To adapt to the shape of the lower pot body, the side wall of the lower pot body is inclined outward relative to the vertical plane from bottom to top. Correspondingly, the installation channel is also inclined outward relative to the vertical plane from bottom to top. The inclination angle formed by the installation channel relative to the vertical plane is denoted as α. Among them, the value range of α is: 15° ≤ α ≤ 20°. The above-mentioned inclined structure design, on the one hand, can make the temperature-sensing end of the temperature-sensing rod as close as possible to the bottom wall of the lower pot body to ensure the heat transfer efficiency between the temperature-sensing rod and the lower pot body; on the other hand, when the fixed shell is subjected to an upward force, it also increases the friction force between the fixed shell and the lower pot assembly, and it is not easy to escape from the installation channel. In particular, when the upper cover assembly is rotationally connected to the fixed shell and the upper cover assembly is in a closed state, (generally, after the upper cover assembly and the lower pot assembly are closed, they are also limited by a buckle at the front side), the inclined setting of the fixed shell can effectively ensure the reliability of the connection between the upper cover assembly and the lower pot assembly, and the user can safely carry the air fryer.
[0020] As an improvement, the first heating element is arranged on the bottom wall of the lower pot body, and the side wall of the lower pot body also has a thermally conductive member extending outward adjacent to the position of its bottom wall. In the state where the fixed shell is installed in place in the installation channel, the temperature-sensing end of the temperature-sensing rod is in contact with the thermally conductive member. The thermally conductive member can generally be selected as a metal thermally conductive member. It can be imagined that the thermally conductive member can be integrally designed with the lower pot body. Thus, it can be understood that the temperature-sensing rod is in direct contact with the lower pot body.
[0021] In order to increase the heat transfer area between the thermally conductive member and the temperature-sensing rod as much as possible and to achieve good positioning of the temperature-sensing rod, the thermally conductive member has a positioning hole penetrating up and down, and the temperature-sensing end of the temperature-sensing rod is limited in the positioning hole.
[0022] In order to achieve the rotational connection between the upper cover assembly and the lower pot assembly, the upper cover assembly includes a cover body, as well as a second heating element, a fan assembly and a controller provided on the cover body. The side part of the cover body has a connecting arm extending outward. The connecting arm is rotatably connected to the top of the fixed shell through a pin shaft extending left and right. Inside the fixed shell, there is a first connecting wire electrically connected to the temperature sensing rod. This first connecting wire passes through at the rotational connection position between the fixed shell and the connecting arm and is electrically connected to the controller. The above structural design enables the upper cover assembly and the temperature sensing assembly to form a combined unit that can be disassembled relative to the lower pot assembly, facilitating the separate cleaning operations of the lower pot assembly and the upper cover assembly.
[0023] In order to simplify the wiring structure of the first heating element on the lower pot assembly, it further includes two wiring terminals connected to the first heating element. The two wiring terminals extend upward from the bottom wall of the installation channel into the installation channel. The bottom of the fixed shell is also provided with two wiring sockets. In the state where the fixed shell is installed in place in the installation channel, the two wiring terminals are correspondingly inserted into the two wiring sockets. Inside the fixed shell, there is a second connecting wire electrically connected to the temperature sensing rod. This second connecting wire passes through at the rotational connection position between the fixed shell and the connecting arm and is electrically connected to the controller.
[0024] Compared with the prior art, the advantages of the present utility model are as follows: The temperature sensing assembly of the air fryer is detachably installed in the installation channel of the lower pot assembly, specifically including a fixed shell and a temperature sensing rod provided at the bottom of the fixed shell. In the state where the fixed shell is installed in place in the installation channel, the temperature sensing end of the temperature sensing rod is in direct or indirect contact with the lower pot body or the temperature sensing end of the temperature sensing rod is arranged adjacent to the lower pot body. This detachable temperature sensing assembly is convenient to disassemble. When it is necessary to detect and repair the temperature sensing device, the temperature sensing assembly can be directly removed, improving the later maintenance efficiency of the air fryer. After the temperature sensing assembly is removed, the lower pot body can be conveniently cleaned, reducing the probability of damage caused by carrying the temperature sensing device for cleaning.

[0038] The present utility model will be further described in detail below in conjunction with the embodiments with reference to the drawings.
[0039] In the description and claims of the present utility model, terms indicating directions, such as "front", "rear", "upper", "lower", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present utility model. However, these terms are used herein only for the convenience of description and are determined based on the exemplary orientations shown in the drawings. Since the embodiments disclosed by the present utility model can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the direction of gravity.
[0040] Figures 1 - 13 A preferred embodiment of the air fryer of the present utility model is shown. The air fryer includes a lower pot assembly, an upper cover assembly, and a temperature sensing assembly.
[0041] See Figure 6 and Figure 7, the cooking pot assembly includes a cooking pot body 10, a base 15, a mounting seat 11, and a first heating element 12. The first heating element 12 is usually an electric heating tube, which is arranged at the bottom of the cooking pot body 10. The electric heating tube has two first wiring terminals 120, and the two first wiring terminals 120 extend to the side of the cooking pot body 10 and extend upward along the side wall of the cooking pot body 10. Specifically, the two first wiring terminals 120 are both terminal posts, and the root positions of the two terminal posts are fixed by a support plate 121, and the support plate 121 is substantially perpendicular to the extending direction of the terminal posts. The side wall of the cooking pot body 10 also has a heat conducting member 13 extending outward adjacent to the position of its bottom wall. Two clamping openings are provided on the heat conducting member 13, and the portions of the above-mentioned electric heating tube connected to the two terminal posts can be correspondingly clamped into the two clamping openings. This structural design can, on the one hand, increase the firmness of the fixation of the electric heating tube, and on the other hand, the heat conducting member 13 is in direct contact with the electric heating tube, improving the heat transfer efficiency. The temperature of the heat conducting member 13 detected by the temperature sensing component in time can relatively accurately reflect the temperature of the heated area of the cooking pot body 10.
[0042] To facilitate the user to take and place food, the cooking pot body 10 is generally in a bowl shape, that is, the side wall of the cooking pot body 10 is inclined outward from the vertical plane from bottom to top towards the outside of the cooking pot body 10. A vertically extending elastic piece 14 is also provided on the side wall of the cooking pot body 10. The lower end of the elastic piece 14 is turned outward (that is, away from the side of the cooking pot body 10) to form a first flanging, and the first flanging is connected and fixed to the above-mentioned support plate 121. The position where the lower part of the elastic piece 14 is connected to the first flanging is fixed to the connecting column 54 on the side wall of the cooking pot body 10 by a screw. The upper end of the elastic piece 14 is turned inward (that is, towards the side of the cooking pot body 10) to form a second flanging, and the end of the second flanging abuts against the side wall of the cooking pot body 10. Thus, the inclination direction of the main body of the elastic piece 14 is substantially the same as the inclination direction of the side wall of the cooking pot body 10.
[0043] The mounting seat 11 is mounted at the position of the elastic piece 14 on the side wall of the cooking pot body 10. A vertically extending mounting channel 110 is defined between the mounting seat 11 and the cooking pot body 10. The height of the top of the mounting seat 11 is substantially the same as the height of the top opening of the cooking pot body 10. The top of the mounting seat 11 forms a mounting opening 1101 communicating with the mounting channel 110. A concave area recessed away from the cooking pot body 10 is formed on the side part of the mounting seat 11 facing the cooking pot body 10, and the concave area is opposite to the elastic piece 14. Thus, the main part of the elastic piece 14 and the mounting seat 11 define the above-mentioned mounting channel 110, that is, the main part of the elastic piece 14 constitutes a part of the inner side wall of the mounting channel 110, and the first flanging of the elastic piece 14 and the corresponding support plate 121 correspondingly constitute a part of the bottom wall of the mounting channel 110. The above two terminal posts extend upward from the bottom wall of the mounting channel 110 into the mounting channel 110.
[0044] See Figure 4, the base 15 is installed at the bottom of the lower pot body 10 and is used to support the lower pot body 10. A clearance space is defined between the position of the first heating element 12 at the bottom of the lower pot body 10 and the base 15 to prevent the base 15 from directly contacting the first heating element 12, achieving the purpose of heat insulation.
[0045] See Figure 3 , the temperature sensing component is a plug 3, which includes a fixed shell 30 and a temperature sensing rod 33 provided at the bottom of the fixed shell 30 and extending downward. The overall shape of the fixed shell 30 is adapted to the shape of the above-mentioned installation channel 110. Thus, the fixed shell 30 can just be inserted into the installation channel 110 from top to bottom through the above-mentioned installation opening 1101 and can be taken out from the installation channel 110. The inside of the fixed shell 30 has a first connecting wire 34 electrically connected to the temperature sensing rod 33. In the state where the fixed shell 30 is installed in place in the installation channel 110, the temperature sensing end (i.e., the lower end) of the temperature sensing rod 33 is in contact with the heat conducting member 13. The heat conducting member 13 can generally be selected as a metal heat conducting member 13. When the lower pot assembly works, the heat generated by the heating of the lower pot body 10 can be transferred to the heat conducting member 13, and the temperature sensing rod 33 can obtain this temperature. In order to increase the heat transfer area between the heat conducting member 13 and the temperature sensing rod 33 as much as possible and to achieve good positioning of the temperature sensing rod 33, the heat conducting member 13 has a positioning hole 130 penetrating up and down, and the temperature sensing end of the temperature sensing rod 33 is correspondingly limited in the positioning hole 130 of the heat conducting member 13.
[0046] To ensure that the fixed shell 30 can be firmly fixed in the installation channel 110, a positioning convex portion 140 protruding toward the inside of the installation channel 110 is provided on one side of the side wall of the elastic piece 14 facing the installation channel 110. The positioning convex portion 140 is a positioning convex point. Correspondingly, a positioning concave portion 300 is provided on the outer side wall of the fixed shell 30, and the positioning concave portion 300 is a positioning concave pit adapted to the above-mentioned positioning convex point.
[0047] See Figure 5 , there is also a notch 1102 on the outer side wall of the mounting seat 11 adjacent to the position of the mounting opening 1101, which laterally penetrates to the installation channel 110. The top region of the side wall of the fixed shell 30 has a protruding boss 36, and the boss 36 has an inwardly concave groove as a handle portion 360, and the opening of the groove faces outward. In the state where the fixed shell 30 is installed in place in the installation channel 110, the above-mentioned boss 36 is correspondingly received in the notch 1102 of the mounting seat 11. When disassembling the temperature sensing component, the operator can hold the groove on the boss 36 of the mounting seat 11 and apply an upward force to pull out the fixed shell 30 upward. This structural design makes the disassembly process of the temperature sensing component more convenient and labor-saving.
[0048] When the temperature-sensing device needs to be detected and repaired, the temperature-sensing component can be directly removed, which improves the later maintenance efficiency of the air fryer. After the temperature-sensing component is removed, the lower pot body 10 can be easily cleaned, reducing the probability of damage caused by cleaning with the temperature-sensing device carried.
[0049] In this embodiment, the upper end of the fixed shell 30 of the temperature-sensing component is rotatably connected to the connecting arm 21 of the upper cover component. The temperature-sensing component can be inserted into the installation channel 110 to be fixed relative to the lower pot body 10 and can be removed from the installation channel 110 to separate the upper cover component from the lower pot body 10. After the temperature-sensing component is inserted into the installation channel 110, the upper cover component can be flipped relative to the lower pot component to realize the opening and closing of the upper cover component relative to the lower pot component. The above structural design makes the upper cover component and the temperature-sensing component form a combined unit that can be disassembled relative to the lower pot component, facilitating the separate cleaning operations of the lower pot component and the upper cover component.
[0050] See Figure 6 , in order to adapt to the inclined structure of the side wall of the lower pot body 10, the installation channel 110 in this embodiment also inclines outward relative to the vertical plane from bottom to top towards the lower pot body 10. Among them, the inclination angle formed by the installation channel 110 relative to the vertical plane is denoted as α, and the value range of α is: 0° < α ≤ 30°, and the preferred value range is 15° ≤ α ≤ 20°. The above inclined structural design, on the one hand, can make the temperature-sensing end of the temperature-sensing rod 33 as close as possible to the bottom wall of the lower pot body 10, shortening the heat transfer path and ensuring the heat transfer efficiency between the temperature-sensing rod 33 and the lower pot body 10; on the other hand, when the fixed shell 30 is stressed upward, it also increases the friction force between the fixed shell 30 and the lower pot component and is not easily removed from the installation channel 110. In particular, when the upper cover component is rotatably connected to the fixed shell 30 and the upper cover component is in the buckled state, (generally, after the upper cover component and the lower pot component are buckled, they are also limited by a buckle at the front side), the inclined setting of the fixed shell 30 can effectively ensure the firmness of the connection between the upper cover component and the lower pot component, and the user can safely carry the air fryer. Of course, in other embodiments of the present application, the installation channel can extend vertically, that is, the inclination angle formed by the extending direction of the installation channel relative to the vertical plane is 0°.
[0051] See Figure 4 and Figure 10, the upper cover assembly includes a cover body 20, and a second heating element 22, a fan assembly 23, and a controller 24 provided on the cover body 20. Among them, the cover body 20 generally includes a glass cover (i.e., the upper cover main body 201) and an upper shell 202 fixedly installed with the glass cover. The above-mentioned second heating element 22, fan assembly 23, and controller 24 are all provided inside the upper shell 202. The second heating element 22 is located below the fan assembly 23. After the fan assembly 23 is started, the air flow heated by the second heating element 22 can circulate in the cooking cavity to heat the food ingredients.
[0052] Continue to refer to Figure 3 , the upper shell 202 extends outward relative to the glass cover to form a connecting arm 21, and the connecting arm 21 is rotatably connected to the top of the fixed shell 30 through a pin shaft extending left and right. To facilitate the rotational connection with the connecting arm 21, when the fixed shell 30 is in place in the installation channel 110, the top end of the fixed shell 30 is exposed outside the top opening of the installation channel 110, and this exposed top part serves as the first connection end 301 connected to the connecting arm 21. One end of the connecting arm 21 away from the cover body 20 serves as the second connection end 210 for connecting to the first connection end 301. The bottom of the second connection end 210 has an upward concave connection groove 211 for receiving the first connection end 301 of the fixed shell 30 therein. A left and right extending rotating shaft 35 is provided on the first connection end 301 of the fixed shell 30, and shaft holes 2110 for rotatably limiting the corresponding rotating shaft 35 are provided on the left and right opposite side walls of the connection groove 211 of the connecting arm 21.
[0053] The first connecting wire 34 electrically connected to the temperature sensing rod 33 in the fixed shell 30 passes through at the position where the fixed shell 30 is rotatably connected to the connecting arm 21 and is electrically connected to the controller 24 inside the upper cover assembly. Generally, an opening can be correspondingly provided at the area where the fixed shell 30 and the connecting arm 21 are rotatably connected for the connecting wire to pass through. However, to avoid the exposed connecting wire affecting the overall aesthetics of the air fryer and the potential safety hazards caused by the external leakage of the connecting wire, the rotating shaft 35 of the fixed shell 30 is axially hollow to form a corresponding lead hole 350. The first connecting wire 34 electrically connected to the temperature sensing rod 33 can pass through the lead hole 350 on the rotating shaft 35, enter the inside of the connecting arm 21 from the fixed shell 30, and be electrically connected to the controller 24.
[0054] Refer to Figure 8 and Figure 9, the bottom of the fixed housing 30 also has two second terminal blocks 31, both of which are wiring sockets and are respectively arranged on the left and right sides of the temperature sensing rod 33. The fixed housing 30 also has a second connecting wire 32 electrically connected to the two second terminal blocks 31. The second connecting wire 32 also passes through the lead hole 350 on the rotating shaft 35 and enters the inside of the connecting arm 21 from the fixed housing 30 to be electrically connected to the controller 24. Specifically, the second connecting wire 32 is also electrically connected to the controller 24 through the lead hole 350 on the rotating shaft 35 and entering the inside of the connecting arm 21 from the fixed housing 30.
[0055] See Figure 12 , the upper cover main body 201 is a glass cover, and an annular edge 4 is also provided at the outer peripheral edge of the upper cover main body 201. The annular edge 4 includes an annular connecting portion 401 and an annular supporting portion 402 extending downward from the annular connecting portion 401. The annular connecting portion 401 has an installation groove 403 for the outer peripheral edge of the upper cover main body 201 to be inserted therein. In order to ensure the sealing performance of the upper cover and prevent hot air from leaking from the outer peripheral edge of the annular edge 4 and the upper cover main body 201 during cooking, an annular seal 43 is provided in the installation groove 403. The inner side of the annular seal 43 has an annular groove 430 for the outer peripheral edge of the upper cover main body 201 to be embedded therein. When the upper cover assembly is in the closed state, the bottom edge of the above-mentioned annular supporting portion 402 abuts against the outer peripheral edge of the lower pot body 10.
[0056] The annular edge 4 of the present embodiment includes an outer ring 41 and an inner ring 42 provided inside the outer ring 41. The outer ring 41 and the inner ring 42 can be fixed by fasteners 60 such as screws. The upper side edge of the outer ring 41 has a first folded edge 411 extending inwardly and folded, and the upper side edge of the inner ring 42 has a second folded edge 421 folded inwardly. The second folded edge 421 is lower than the first folded edge 411. Thus, the gap between the first folded edge 411 and the second folded edge 421 forms the above-mentioned installation groove 403. The end of the first folded edge 411 also has a retaining edge 4111 that gradually slopes downward from outside to inside. The bottommost part of the retaining edge 4111 can be in contact with the upper surface of the glass cover. In this way, the retaining edge 4111 can correspondingly block the annular seal 43, ensuring the overall aesthetics of the cover body 20. The lower side edge of the outer ring 41 is turned up from the inside to form a curled edge 412. The curled edge 412 constitutes a limiting stop portion. During installation, the lower side edge of the inner ring 42 can abut against the curled edge 412. The design of the curled edge 412 further ensures the strength of the annular edge 4.
[0057] See Figure 13, a first handle portion 50 is provided on the annular support portion 402 of the annular edge 4. There are two first handle portions 50, which are respectively located on the left and right sides of the upper cover body 201. The first handle portions 50 are arranged on the left and right sides of the upper cover body 201. During the process of opening the cover body 20 by the handle, the hands of the operator can avoid the upper part of the pot body and prevent being scalded by the hot air. Specifically, the first handle portion 50 includes an arc-shaped connecting portion 51 extending vertically and a gripping portion 52 extending outward from the arc-shaped connecting portion 51. The bending radian of the inner side wall of the arc-shaped connecting portion 51 is basically the same as the bending radian of the outer side wall of the annular support portion 402. The arc-shaped connecting portion 51 is connected to the outer side of the annular support portion 402 through a fastener 60. More specifically, the fastener 60 is a screw, and the screw can sequentially pass through the inner ring 42 and the outer ring 41 from the inside to the outside and be connected to the arc-shaped connecting portion 51 of the first handle portion 50. The inner side of the arc-shaped connecting portion 51 has a connecting column 54 protruding towards the annular support portion 402, and the screw passes through the inner ring 42 and the outer ring 41 from the inside and is connected to the connecting column 54. The inner side of the arc-shaped connecting portion 51 also has a limiting protrusion 53 protruding towards the annular support portion 402. After the first handle portion 50 is installed in place, the outer wall of the annular support portion 402 abuts against the limiting protrusion 53 and the connecting column 54, and an insulating gap 500 is formed between the main body of the annular support portion 402 and the arc-shaped connecting portion 51. The insulating gap 500 can play a role in heat insulation, reduce the heat transfer from the pot body to the first handle portion 50, and prevent the user from being scalded when contacting the first handle portion 50.
[0058] See Figure 12 , corresponding to the first handle portion 50 on the cover body 20 described above, a second handle portion 13 extending outward is further provided on the side wall of the lower pot body 10. When the upper cover assembly is in a state of closing the lower pot body 10, the first handle portion 50 of the cover body 20 is located above the second handle portion 13 of the lower pot body 10. The bottom wall of the first handle portion 50 is attached to the top wall of the second handle portion 13, and a part of the first handle portion 50 is located outside the vertical projection of the second handle portion 13 in the vertical direction. It can also be understood that a part of the side of the second handle portion 13 is missing relative to the first handle portion 50. Thus, a part of the first handle portion 50 is exposed, as Figure 11As shown, a notch 130 is recessed in the middle area of the side of the second handle portion 13 of the lower pot body 10. Then, the portion of the first handle portion 50 corresponding to the position above the notch 130 can be understood as being exposed relative to the second handle portion 13. When the upper cover assembly is in the closed state, the first handle portion 50 and the second handle portion 13 are fitted together to form a complete handle structure. When carrying the air fryer, the user can hold the first handle portion 50 and the second handle portion 13 simultaneously, making the process of carrying and transferring the air fryer safer and more reliable. On the other hand, since a part of the first handle portion 50 is located outside the vertical projection of the second handle portion 13 in the vertical direction, when it is necessary to open the upper cover assembly, the user can apply an upward force to the exposed part of the first handle portion 50 relative to the second handle portion 13 to easily open it, improving the user experience.
[0059] In this embodiment, the annular edge 4 outside the upper cover main body 201 has a downwardly extending annular support portion 402. The setting of this annular support portion 402 increases the height of the upper cover main body 201. A higher upper cover means a larger space inside the fryer, which can accommodate more or larger food, and this is particularly useful for occasions where a large amount of food needs to be cooked at one time, greatly improving the cooking efficiency and convenience. On the other hand, the increase in the height of the upper cover main body 201 makes the perspective effect of the user observing the cooking situation in the cooking cavity through the upper cover main body 201 better, improving the user experience.
[0060] The air fryer of this embodiment can be a conventional air fryer or a multifunctional air fryer with functions of frying, grilling, and steaming.
[0061] On the basis of the above embodiments, other embodiments can be obtained by replacing and improving relevant technical features. For example, in the state where the fixed shell 30 is installed in place in the installation channel 110, the temperature sensing end of the temperature sensing rod 33 on the fixed shell 30 may not be in direct or indirect contact with the lower pot body 10, but the temperature sensing end of the temperature sensing rod 33 is arranged adjacent to the bottom wall of the lower pot body 10, that is, the temperature sensing end of the temperature sensing rod 33 does not contact the lower pot body 10, but is close to the wall of the lower pot body 10, and the heat of the lower pot body 10 is mainly transferred to the temperature sensing rod 33 by thermal radiation. Another example is that in addition to the above-mentioned cooperation mode of the positioning convex portion 140 and the positioning concave portion 300 between the fixed shell 30 and the fixed seat of the lower pot assembly, a locking structure capable of locking and unlocking can also be adopted between the two for fixation. Another example is that the above-mentioned mounting seat 11 is not limited to the seat structure attached to only one area (such as the rear side of the lower pot body 10) on the side wall of the lower pot body 10, and can also be an annular seat surrounding the outside of the lower pot body 10.
