Description

Technical Field

[0001] The utility model relates to the technical field of air fryers, in particular to an upper cover structure of an air fryer and 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. The air fryer includes a flip-top air fryer and a pull-out air fryer. Among them, the flip-top air fryer generally includes a base with a cooking cavity inside and a head (i.e., an upper cover assembly) that is flipped and closed on the base. A cooking pot is provided in the cooking cavity, a hot air cavity is provided in the head, a hot air component is provided in the hot air cavity, the head is closed on the base, and the heat generated by the hot air component is input into the cooking cavity to cook the food ingredients in the cooking pot. In order to facilitate the user to view the cooking situation in the cooking cavity, the head generally uses a transparent and see-through glass cover. For example, the Chinese utility model patent application of CN202222585342.7 (the authorized announcement number is: CN218164996U) discloses such a flip-top air fryer.

[0003] However, the air fryer in the above patent application still has certain deficiencies. First of all, the four peripheral edges of the existing cover body main body are closely attached to the cooking pot, and its height is relatively low. The viewing angle of observing the cooking cavity through the glass upper cover is limited, and the visual effect of observing the cooking situation of the food is not good, reducing the user experience. On the other hand, due to the low height of the cover body, the cooking space in the air fryer is also relatively small, which is very inconvenient for occasions where a large amount of food needs to be cooked at one time. Secondly, the handles of the upper cover assembly of the air fryer are mostly arranged on the front side. During the process of opening the cover through the front handle, the operator's hand is just above the cooking pot and is easily scalded by the hot air.

[0004] Therefore, the existing air fryer still needs to be further improved. Summary of the Utility Model

[0005] The first technical problem to be solved by the utility model is to provide an upper cover structure of an air fryer with a better viewing effect of observing the cooking situation in the cooking cavity and a larger cooking space in view of the current situation of the prior art.

[0006] The second technical problem to be solved by the utility model is to provide an upper cover structure of an air fryer with a more reasonable handle setting position and convenient for the user to open and close the upper cover in view of the current situation of the prior art.

[0007] The third technical problem to be solved by the utility model is to provide an air fryer applying the above upper cover structure in view of the current situation of the prior art.

[0008] The technical solution adopted by the utility model to solve the first technical problem is:

[0009] The upper cover structure of an air fryer, comprising:

[0010] The upper cover main body;

[0011] The annular edge wrapping disposed at the outer peripheral edge of the upper cover main body;

[0012] The annular edge wrapping includes an annular connecting portion and an annular supporting portion extending downward from the annular connecting portion. The annular connecting portion is provided with a mounting groove for the outer peripheral edge of the upper cover main body to be inserted therein.

[0013] Generally, the annular edge wrapping can be an integral part. However, for the convenience of cleaning and cost reduction in processing, the annular edge wrapping includes an outer ring and an inner ring disposed inside the outer ring. The upper side edge of the outer ring has a first folded edge extending inwardly and turning over, and the upper side edge of the inner ring has a second folded edge turning inwardly. The second folded edge is lower than the first folded edge, and the gap between the first folded edge and the second folded edge forms the mounting groove.

[0014] 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 wrapping and the upper cover main body during the cooking process, the upper cover main body is a glass cover. An annular sealing member is provided in the mounting groove. The inner side of the annular sealing member has an annular groove for the outer peripheral edge of the upper cover main body to be embedded therein. The end of the first folded edge also has a retaining edge that gradually inclines downward from outside to inside.

[0015] In order to ensure the overall strength of the annular edge wrapping, a limiting and blocking portion protruding radially inward is further provided at the lower side edge of the outer ring, and the lower side edge of the inner ring abuts against the limiting and blocking portion.

[0016] In order to simplify the structure of the annular edge wrapping, the lower side edge of the outer ring is turned up from the inside to form a curled edge, and this curled edge is the limiting and blocking portion.

[0017] In order to facilitate the user to hold and open / close the upper cover, a first handle portion is further included and installed on the annular supporting portion.

[0018] The technical solution adopted by the present utility model to solve the second technical problem is as follows: There are two first handle portions, which are respectively located on the left and right sides of the upper cover main body. The first handle portions are arranged on the left and right sides of the upper cover main body. During the process of the operator opening the cover body with the handle, the operator's hand can avoid the upper part of the pot body, thus preventing being scalded by the hot air.

[0019] As an improvement, the first handle portion includes an arc-shaped connecting portion extending vertically and a gripping portion extending outward from the arc-shaped connecting portion. The arc-shaped connecting portion is connected to the outside of the annular support portion by a fastener. The inner side of the arc-shaped connecting portion further has a limiting protrusion protruding toward the annular support portion. The outer wall of the annular support portion abuts against the limiting protrusion, and a heat insulation gap is formed between the main body of the annular support portion and the arc-shaped connecting portion. The heat insulation gap can play a role in heat insulation, reducing the transfer of heat from the pot body to the first handle portion and preventing the user from being scalded when contacting the first handle portion.

[0020] The technical solution adopted by the present utility model to solve the third technical problem is as follows:

[0021] An air fryer, comprising:

[0022] A lower pot assembly, including a lower pot body with an open top;

[0023] 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;

[0024] The cover body adopts the upper cover structure of the above-mentioned air fryer.

[0025] The technical solution adopted by the present utility model to solve the third technical problem is as follows:

[0026] In a preferred embodiment, an air fryer, comprising:

[0027] A lower pot assembly, including a lower pot body with an open top;

[0028] 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;

[0029] The cover body adopts the upper cover structure of the above-mentioned air fryer. The side wall of the lower pot body further has a second handle portion extending outward. When the upper cover assembly is in a state of closing the lower pot body, the bottom wall of the first handle portion is attached to the top wall of the second handle portion, and a part of the first handle portion is located outside the vertical projection of the second handle portion in the vertical direction.

[0030] When the upper cover assembly is in the closed state, the first handle part and the second handle part are attached to form a complete handle structure. When carrying the air fryer, the user can hold the first handle part and the second handle part simultaneously, making the handling and transfer process of the air fryer safer and more reliable. On the other hand, since a part of the first handle part has a positive projection in the vertical direction outside the positive projection of the second handle part in the vertical direction, when the upper cover assembly needs to be opened, the user can hold the exposed part of the first handle part relative to the second handle part and apply an upward force to easily open it, improving the user experience.

[0031] Compared with the prior art, the advantages of the present utility model are as follows: The annular edge outside the upper cover body has a downwardly extending annular support part. The setting of this annular support part increases the height of the upper cover body. A higher upper cover means a larger space inside the fryer, which can accommodate more or larger foods, 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 body makes the viewing angle effect of the user observing the cooking situation in the cooking cavity through the upper cover body better, improving the user experience.

[0045] The present utility model will be further described in detail below in conjunction with the embodiments with reference to the drawings.

[0046] 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 purpose of convenient 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.

[0047] Figures 1 - 13 Shows the upper cover structure of the air fryer of the present utility model and a preferred embodiment of the air fryer. The air fryer includes a lower pot assembly, an upper cover assembly, and a temperature sensing assembly.

[0048] See Figure 6 and Figure 7, the cooking pot component 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 terminal ends 120, and the two first terminal ends 120 extend to the side part of the cooking pot body 10 and extend upward along the side wall of the cooking pot body 10. Specifically, the two first terminal ends 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. There is also a heat conducting member 13 extending outward on the side wall of the cooking pot body 10 near the position where its bottom wall is located. Two clamping openings are formed on the heat conducting 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 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.

[0049] To facilitate the user to take and place food, the cooking pot body 10 is generally in a bowl-shaped structure, that is, the side wall of the cooking pot body 10 inclines outward from the bottom to the top relative to the vertical plane towards the outside of the cooking pot body 10. There is also a vertically extending elastic piece 14 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.

[0050] The mounting seat 11 is installed at the position of the elastic piece 14 on the side wall of the cooking pot body 10. A vertically extending installation 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. An installation opening 1101 communicating with the installation channel 110 is formed at the top of the mounting seat 11. 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 installation channel 110, that is, the main part of the elastic piece 14 constitutes a part of the inner side wall of the installation 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 installation channel 110. The above-mentioned two terminal posts extend upward from the bottom wall of the installation channel 110 into the installation channel 110.

[0051] 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.

[0052] 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 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 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 that penetrates 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.

[0053] To ensure that the fixed shell 30 can be firmly fixed in the installation channel 110, a positioning convex portion 140 protruding toward the installation channel 110 is provided on 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.

[0054] See Figure 5 , a notch 1102 that laterally penetrates 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 convex platform 36 protruding outward is provided in the top region of the side wall of the fixed shell 30. The convex platform 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 convex platform 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 convex platform 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.

[0055] When it is necessary to detect and repair the temperature sensing device, 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 conveniently cleaned, reducing the probability of damage caused by cleaning with the temperature sensing device carried.

[0056] 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 enables the upper cover component and the temperature sensing component to 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.

[0057] 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 of 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, 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 stressed upward, it also increases the friction force between the fixed shell 30 and the lower pot component, making it not easy to be 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 inclination angle formed by the extending direction of the installation channel relative to the vertical plane is 0°.

[0058] 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 airflow heated by the second heating element 22 can circulate in the cooking cavity to heat the food ingredients.

[0059] 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.

[0060] 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 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 hazard 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.

[0061] 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 enters the inside of the connecting arm 21 from the fixed housing 30.

[0062] 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.

[0063] 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 inward and turned over, and the upper side edge of the inner ring 42 has a second folded edge 421 turned inward. 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 bottom 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 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.

[0064] 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 transfer of the heat of the pot body to the first handle portion 50, and prevent the user from being scalded when contacting the first handle portion 50.

[0065] 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 orthogonally projected outside the orthographic 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 part 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 handling and transfer process of 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.

[0066] 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. 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.

[0067] The air fryer of this embodiment can be a conventional air fryer or a multi-functional air fryer with functions of frying, grilling, and steaming.

[0068] On the basis of the above embodiments, other embodiments can be obtained by replacing and improving relevant technical features. For example, when the fixing shell 30 is in the installed position 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 may be 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 to fix the two. 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.
