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 fried food ingredients. One of the main components of an air fryer is a heating component, which is responsible for emitting heat, transmitting it to the food through the air, and heating the food. During 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 (authorization publication number: CN215937122U) discloses a multi-functional air fryer, which includes a pot cover and a pot body pivotally connected to the pot cover. A hot air assembly is provided inside the pot cover. The pot body includes an inner pot and an outer pot. A heat conduction assembly and a temperature sensing element are provided between the inner pot and the outer pot. The pot cover is connected to the pot body through a rotating mechanism. The rotating mechanism includes a back plate and a rotating shaft rotatably connected to the back plate. The rotating shaft is connected to the pot body, and the back plate is connected to the pot cover.

[0004] There are still certain deficiencies in the air fryer in the above patent application. Since the pot cover and the pot body of the air fryer are connected through a rotating mechanism to form an integral structure that cannot be disassembled, its volume is relatively large. And due to the limitation of the opening angle, there will be some hard-to-reach corners and crevices that are difficult to clean thoroughly. These areas may remain with food residues and oil stains, and long-term accumulation will affect the hygiene condition and cooking effect of the air fryer. On the other hand, during cleaning, due to the structural limitation, users may not be able to use certain specific cleaning tools or cleaning agents to deeply clean the inside of the fryer. For example, a brush or a sponge may not be able to reach into some crevices, resulting in incomplete cleaning. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an air fryer that is convenient for cleaning operations in view of the current situation of the prior art.

[0006] The technical solution adopted by the utility model to solve the above technical problem is: an air fryer, comprising:

[0007] A lower pot assembly, including a lower pot body with an open top;

[0008] An upper cover assembly, including a cover body, which is connected to the lower pot body in a manner that can rotate relative to the lower pot body and can open and close the open top of the lower pot body;

[0009] The lower pot assembly defines an installation channel extending vertically. The installation channel is located on one side of the lower pot body and is open at the top. The side part of the cover body has a connecting arm extending outward. The connecting arm is provided with an insertion block that can rotate relative to the connecting arm around an axis extending horizontally. The insertion block can be inserted into the installation channel to be fixed relative to the lower pot body and can be disengaged from the installation channel to separate the upper cover assembly from the lower pot body.

[0010] The "vertical" in the above-mentioned "installation channel extending vertically" is not limited to the vertically extending direction, and it can be slightly inclined relative to the vertical direction (such as an inclination angle less than 30°).

[0011] In order to facilitate the rotational connection with the connecting arm, when the insertion block is in the installed position in the installation channel, the top end of the insertion block exposes the top opening of the installation channel and serves as the first connection end connected to the connecting arm.

[0012] In order to ensure that the upper cover assembly and the lower pot assembly can be firmly attached after being closed, the end of the connecting arm away from the cover body serves as the second connection end used to connect to the first connection end. The bottom of the second connection end has an upwardly concave connection groove for receiving the first connection end of the insertion block. The first connection end is provided with a rotating shaft extending left and right, and the left and right opposite side walls of the connection groove are provided with shaft holes for rotatably limiting the corresponding rotating shafts therein.

[0013] In order to realize the electrical connection between the controllers of the lower pot assembly and the upper cover assembly, the cover body is provided with a controller. The bottom of the lower pot body is also provided with a first heating element for heating the lower pot body. The first heating element has two first wiring terminals. The two first wiring terminals are arranged at the bottom position of the installation channel. The bottom of the insertion block is provided with two second wiring terminals electrically connected to the controller. When the fixing shell is in the installed position in the installation channel, the two first wiring terminals are respectively electrically connected to the two second wiring terminals.

[0014] As an improvement, both of the two first wiring terminals are terminal posts. The two terminal posts extend upward from the bottom wall of the installation channel into the installation channel. The two second wiring terminals are two wiring sockets provided at the bottom of the insertion block. When the fixing shell is in the installed position in the installation channel, the two terminal posts are correspondingly inserted into the two wiring sockets.

[0015] To avoid the exposed connecting wire affecting the overall aesthetics of the air fryer and the potential safety hazards caused by the exposed connecting wire, the plug block includes a fixed shell and a second connecting wire disposed within the fixed shell and electrically connected to the two second terminal blocks. The axial center of the rotating shaft is hollow to form a lead hole for the second connecting wire to enter the interior of the connecting arm from the fixed shell. The second connecting wire that enters the connecting arm through the lead hole is electrically connected to the controller.

[0016] To simplify the installation structure of the temperature sensing rod, the bottom of the plug block further has a temperature sensing rod extending downward, which is electrically connected to the controller. When the plug block is installed in place in the installation channel, the lower end of the temperature sensing rod extends to the position where the bottom of the lower cooking pot is located. By arranging the temperature sensing rod on the plug block, it can be conveniently removed along with the plug block. When it is necessary to detect and repair the temperature sensing device, the temperature sensing component can be directly removed, improving the later maintenance efficiency of the air fryer. After the temperature sensing component is removed, the lower cooking pot can be conveniently cleaned, reducing the probability of damage caused by cleaning while carrying the temperature sensing device.

[0017] As an improvement, the upper cover assembly further includes a second heating element and a fan assembly disposed on the cover body.

[0018] To form the above installation channel, an installation seat is further provided on the side wall of the lower cooking pot, and the installation channel is defined on the installation seat or between the installation seat and the lower cooking pot. The above installation seat can be an annular seat body surrounding the outside of the lower cooking pot, or a seat body structure attached only to a region (such as the rear side of the lower cooking pot) on the side wall of the lower cooking pot.

[0019] In some embodiments of the present application, the installation channel may extend vertically, that is, the inclination angle formed by the extension direction of the installation channel relative to the vertical plane is 0°. However, for the convenience of users to take and place food, the lower cooking body is generally in a bowl shape. To match the shape of the lower cooking body, the side wall of the lower cooking body inclines outward relative to the vertical plane from bottom to top. Correspondingly, the installation channel on the mounting seat also inclines outward relative to the vertical plane from bottom to top. The inclination angle formed by the installation channel on the mounting seat relative to the vertical plane is denoted as α. Among them, the value range of α is: 0° < α ≤ 30°, and the preferred value range 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 cooking body, ensuring the heat transfer efficiency between the temperature sensing rod and the lower cooking body; on the other hand, when the fixed shell is stressed upward, it also increases the friction between the fixed shell and the lower cooking assembly, making it not easy to escape from the installation channel. In particular, when the upper cover assembly is rotatably connected to the fixed shell, when the upper cover assembly is in the closed state, (generally, after the upper cover assembly and the lower cooking 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 cooking assembly, and users can safely carry the air fryer.

[0020] Compared with the prior art, the advantages of the present utility model are as follows: A rotatable insertion block is provided on the connecting arm of the cover body of the upper cover assembly. The insertion block can be correspondingly inserted into the vertically extending installation channel of the lower cooking assembly to be fixed relative to the lower cooking body and can also be disengaged from the installation channel to separate the upper cover assembly from the lower cooking body. This vertical direct insertion assembly method ensures the convenience of assembling and disassembling the upper cover assembly and the lower cooking assembly. During installation, the insertion block can be directly inserted into the installation channel from top to bottom. After installation, the vertical insertion method between the upper cover assembly and the lower cooking assembly also ensures the reliability between the two. During cleaning, the upper cover assembly and the lower cooking assembly can be disassembled and cleaned separately, making the cleaning more thorough and improving the user experience.

[0034] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] 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 here 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 used as explanations 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.

[0036] 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.

[0037] See Figure 6 AndFigure 7 , the cooking pot assembly includes a lower cooking pot 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 lower cooking pot 10. The electric heating tube has two first connection terminals 120, and the two first connection terminals 120 extend to the side of the lower cooking pot 10 and extend upward along the side wall of the lower cooking pot 10. Specifically, the two first connection 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 lower cooking pot 10 also has a thermally conductive member 13 extending outward adjacent to the position of its bottom wall. Two clamping openings are formed on the thermally conductive member 13, and the part 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 fixing reliability of the electric heating tube, and on the other hand, the thermally conductive member 13 is in direct contact with the electric heating tube, improving the heat transfer efficiency. The temperature of the thermally conductive member 13 detected by the temperature sensing component in time can relatively accurately reflect the temperature of the heated area of the lower cooking pot 10.

[0038] To facilitate the user to take and place food, the lower cooking pot 10 is generally in a bowl shape, that is, the side wall of the lower cooking pot 10 is inclined outward relative to the vertical plane from bottom to top towards the outside of the lower cooking pot 10. A vertically extending elastic piece 14 is also provided on the side wall of the lower cooking pot 10. The lower end of the elastic piece 14 is turned outward (that is, away from the side of the lower cooking pot 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 lower cooking pot 10 by screws. The upper end of the elastic piece 14 is turned inward (that is, towards the side of the lower cooking pot 10) to form a second flanging, and the end of the second flanging abuts against the side wall of the lower cooking pot 10. Thus, the inclined direction of the main body of the elastic piece 14 is substantially the same as the inclined direction of the side wall of the lower cooking pot 10.

[0039] The mounting seat 11 is mounted at the position of the elastic piece 14 on the side wall of the lower cooking pot 10. A vertically extending mounting channel 110 is defined between the mounting seat 11 and the lower cooking pot 10. The height of the top of the mounting seat 11 is substantially the same as the height of the top opening of the lower cooking pot 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 lower cooking pot 10 is formed on the side part of the mounting seat 11 facing the lower cooking pot 10, and the concave area faces 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-mentioned two terminal posts extend upward from the bottom wall of the mounting channel 110 into the mounting channel 110.

[0040] SeeFigure 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.

[0041] See Figure 3 As shown, 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 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 interior 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.

[0042] 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.

[0043] See Figure 5 As shown, a notch 1102 laterally penetrating to the installation channel 110 is further provided on the outer side wall of the mounting seat 11 adjacent to the position of the installation opening 1101. A boss 36 protruding outward is provided in the top region of the side wall of the fixed shell 30. 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.

[0044] 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.

[0045] 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 withdrawn 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.

[0046] 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 inclined angle formed by the installation channel 110 relative to the vertical plane is denoted as α, where the value range of α is: 0° < α ≤ 30°, and the preferred value range is 15° ≤ α ≤ 20°. The above inclined structure 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 subjected to an upward force, it also increases the friction force between the fixed shell 30 and the lower pot component and is not easily withdrawn 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 reliability 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 inclined angle formed by the extending direction of the installation channel relative to the vertical plane is 0°.

[0047] 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 in 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 chamber to heat the food ingredients.

[0048] Continue to refer to Figure 3 , the upper shell 202 extends outward relative to the glass cover to form a connecting arm 21. 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 installed in place in the installation channel 110, the top end of the fixed shell 30 is exposed out of 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-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.

[0049] The first connecting wire 34 electrically connected to the temperature sensing rod 33 in the fixed shell 30 passes through the position where the fixed shell 30 is rotatably connected to the connecting arm 21 and is electrically connected to the controller 24 in the upper cover assembly. Generally, an opening can be correspondingly provided at the area position 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 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.

[0050] 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.

[0051] 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 annular edge 4 and the outer peripheral edge of the upper cover main body 201 during the cooking process, 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.

[0052] 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 turning over, and the upper side edge of the inner ring 42 has a second folded edge 421 turning 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 stop edge 4111 that gradually slopes downward from outside to inside. The bottommost part of the stop edge 4111 can be in contact with the upper surface of the glass cover. In this way, the stop 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 curled upward 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.

[0053] 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 holding 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.

[0054] See Figure 12 , corresponding to the first handle portion 50 on the cover body 20 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, there is a notch 130 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 orthogonally projected outside the orthographic projection of the second handle portion 13 in the vertical direction, when the upper cover assembly needs to be opened, 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.

[0055] The annular edge 4 outside the upper cover main body 201 of this embodiment has a downwardly extending annular support portion 402. The setting of the 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 viewing angle effect of the user observing the cooking situation in the cooking cavity through the upper cover main body 201 better, improving the user experience.

[0056] The air fryer of this embodiment can be a conventional air fryer or a multi-functional air fryer with both frying and grilling functions and steaming functions.

[0057] 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 fixing shell 30 is installed in place in the installation channel 110, the temperature sensing end of the temperature sensing rod 33 on the fixing 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. For another example, in addition to the above-mentioned cooperation method of the positioning convex portion 140 and the positioning concave portion 300 between the fixing shell 30 and the fixing seat of the lower pot assembly, a locking structure capable of locking and unlocking can also be used between the two for fixation. For another example, the above-mentioned mounting seat 11 is not limited to the seat body 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 body surrounding the lower pot body 10.
