Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to an air fryer. Background Technology

[0002] Common air fryers have a drawer-type structure. A drawer-type air fryer includes a pot body and a fryer assembly that can be pulled in and out of the pot body. The fryer assembly is pushed into the cooking chamber through an opening on the side wall of the pot body. After air frying, the fryer assembly is pulled out through the opening. The fryer assembly is placed roughly horizontally inside the cooking chamber. If the air fryer tilts or leans, the fryer assembly can easily fall out of the cooking chamber. Furthermore, during air frying, the fryer assembly can easily be accidentally pulled out, interrupting the air frying process and potentially causing burns to the user.

[0003] Based on this, Chinese patent CN218279380U discloses an air fryer, in which one of the inner bottom wall of the opening of the main body and the bottom wall of the inner pot fixing frame is provided with a retractable pin, and the other is provided with an insertion part for inserting the pin. When the fryer assembly is pushed into the cooking cavity through the opening and into place, the pin can extend to insert into the insertion part. By limiting the pin with the insertion part, the fryer assembly can be effectively prevented from easily falling out of the cooking cavity, improving the stability of the fryer assembly. When it is necessary to remove the fryer assembly, simply pull the fryer assembly outward to squeeze the pin back and move it out of the insertion part, thus releasing the locking between the main body and the fryer assembly.

[0004] However, during air fryer transportation, the fryer assembly is pushed into the cooking chamber, meaning the pin and socket are in a plug-in engagement state. However, the fryer assembly will wobble relative to the main unit, especially lateral wobble perpendicular to the insertion direction. This causes the pin to be resisted by the inner wall of the socket, resulting in significant shearing force on the pin, making it prone to deformation or even damage. Utility Model Content

[0005] This invention provides an air fryer to solve the problem that when the air fryer components are pushed into the cooking chamber, especially during the transport of the air fryer, the components shake relative to the pot body, causing the latch to be subjected to large shearing forces and easily damaged.

[0006] The technical solution adopted in this utility model is as follows:

[0007] An air fryer includes an outer shell with a cooking cavity and an air fryer assembly. One side of the outer shell has an opening communicating with the cooking cavity. The air fryer assembly can be pushed and pulled into and out of the cooking cavity through the opening. The bottom of the cooking cavity has an upwardly protruding elastic pin. The bottom of the air fryer assembly has a corresponding insertion hole for the elastic pin, and the elastic pin can be inserted into the insertion hole. A protective rib is also provided at the bottom of the cooking cavity near the elastic pin. The bottom of the air fryer assembly has a limiting groove that cooperates with the protective rib. The protective rib extends along the pushing and pulling direction of the air fryer assembly and covers the elastic pin in the pushing and pulling direction.

[0008] In this invention, a protective rib is provided at the bottom of the cooking cavity, which engages with the limiting groove on the fryer assembly. This ensures that when the fryer assembly is pushed into the cooking cavity, its lateral swaying perpendicular to the insertion direction is stopped by the limiting groove wall and the protective rib. This reduces the swaying of the fryer assembly and, when swaying occurs, shifts the force to the limiting groove and the protective rib, thereby reducing the force on the elastic pin, ensuring its integrity, and lowering the possibility of breakage. Furthermore, the protective rib is positioned adjacent to the elastic pin, making the engagement position of the protective rib and the limiting groove, i.e., the limiting position of the fryer assembly, closer to the engagement position of the elastic pin and the insertion hole. This more effectively prevents changes in the relative position of the elastic pin and the insertion hole, thus reducing the shear force on the elastic pin during lateral relative movement.

[0009] Furthermore, after the protective rib and the limiting groove are inserted and matched, the part of the protective rib that is inserted into the limiting groove in the length direction of the protective rib forms a protective area. The protective rib covers the elastic pin in the length direction, so that the elastic pin is located in the protective area. This further improves the protective effect of the protective rib on the elastic pin when the fryer assembly shakes laterally relative to the outer shell. It not only reduces the shaking of the fryer assembly, but also transfers the stopping force between the fryer assembly and the outer shell to the protective rib, which mainly bears the force, reducing the force on the elastic pin.

[0010] There are two protective ribs, which are spaced apart in a direction perpendicular to the push-pull direction of the fryer assembly. There are two elastic pins, which are located between the two protective ribs.

[0011] In this design, there are two flexible pins and two protective ribs, both spaced apart along the insertion direction. This makes the limiting effect of the flexible pins on the fryer assembly, as well as the limiting grooves and protective ribs on the fryer assembly, more stable and reliable. The two protective ribs are spaced further apart, which not only provides limiting effect closer to both ends of the fryer assembly, but also evenly distributes the stopping force between the fryer assembly and the outer shell across the two protective ribs, resulting in more uniform stress distribution. Furthermore, for the outer shell, the greater distance between the two protective ribs also disperses the stress, preventing stress concentration and damage. The two flexible pins are close together, facilitating insertion into the sockets and reducing manufacturing errors to a certain extent, ensuring accurate alignment of the two sockets and the flexible pins.

[0012] The fryer assembly includes a pot body and a handle portion located on the outside of the pot body, with a limiting groove located on the handle portion.

[0013] In this design, the pot body typically extends into the cooking cavity, directly contacting the high-temperature environment inside, while the handle is located outside the cooking cavity, where the temperature is relatively lower. Therefore, the pot body is generally made of metal, and the handle is made of plastic. By machining the limiting groove into the handle, two advantages are made: firstly, plastic is easier to process, saving costs and improving processing efficiency; secondly, during cooking, the pot body generates a high temperature, while the handle remains relatively cool. Therefore, the combination of the limiting groove and the protective rib reduces heat transfer, preventing the protective rib from directly contacting the hot pot body and deforming due to heat.

[0014] In the pushing and pulling direction of the fryer assembly, the extension length of the limiting groove is not less than the extension length of the protective rib.

[0015] In this design, after the protective rib and the limiting groove are inserted and matched, the protective rib is completely contained within the limiting groove. This makes the connection between the two more stable and reliable, reducing the possibility of the protective rib coming out of the limiting groove due to shaking of the fryer assembly. On the other hand, the limiting groove can also work with the protective rib to guide the pushing and pulling of the fryer assembly, limiting the direction of the user's pushing and pulling operation of the fryer assembly, improving the smoothness of operation and reducing jamming.

[0016] The limiting groove has an open end and an insertion end along the push-pull direction of the fryer assembly. The groove walls on both sides of the open end extend in opposite directions to form a guide slope at the open end.

[0017] In this design, the wall of the limiting groove expands outward at the opening end, forming an open structure. This guides the engagement of the limiting groove and the protective rib, as well as the insertion of the fryer assembly, making the insertion of the protective rib into the limiting groove easier and reducing the sticking sensation when the fryer assembly is pushed into the cooking cavity. Furthermore, the outwardly expanding groove wall corrects the position of the fryer assembly during insertion into the cooking cavity. Even if the user does not center the fryer assembly at the opening and slightly offsets it, the limiting groove contacts the guide slope during insertion. The guide slope guides the protective rib, allowing the fryer assembly to laterally align during movement, ensuring it is inserted into the cooking cavity in a centered position. This prevents increased resistance when pushing or pulling the fryer assembly in an unequal position, improving the user experience.

[0018] The bottom of the cooking cavity is also provided with an upwardly protruding support rib. The support rib extends along the pushing and pulling direction of the fryer assembly. The bottom of the fryer assembly is isolated from the bottom wall of the cooking cavity by the support rib. The protrusion height of the protective rib is lower than that of the support rib.

[0019] In this design, the support ribs contact the bottom of the fryer assembly, providing support while maintaining a gap between the fryer assembly and the bottom wall of the cooking cavity. This prevents severe scratching between the bottom wall of the cooking cavity and the coating on the bottom of the fryer assembly, thus preventing wear and tear and effectively extending the lifespan of the fryer assembly. Furthermore, the support ribs extend along the pushing and pulling direction of the fryer assembly, guiding its movement and making it easier and less strenuous to place and remove.

[0020] Because the support ribs have a certain length, they can increase the contact area with the fryer components, which not only improves the support stability of the fryer components, but also makes it easier for users to slide the fryer components along the support ribs, thus improving the user experience.

[0021] There are two support ribs, which are spaced apart in a direction perpendicular to the push-pull direction of the fryer assembly. The protective rib is located between the two support ribs and is positioned closer to the opening relative to the support ribs.

[0022] In this design, the support ribs are positioned closer to the left and right ends of the fryer assembly. Therefore, when the fryer assembly is pushed into the cooking cavity, the support ribs provide more stable support, preventing the fryer assembly from tilting inside the cooking cavity. The protective ribs are closer to the opening, allowing them to work in conjunction with the limiting groove to indicate when the fryer assembly is fully inserted. Once the protective rib stops against the rear wall of the limiting groove, it indicates that the fryer assembly is in place, at which point the user receives clear force feedback and cannot push the fryer assembly any further.

[0023] The air fryer also includes a mounting bracket, with protective ribs and support ribs integrally formed on the mounting bracket and protruding upwards. The outer shell includes a base located below the cooking cavity. A metal base plate is provided at the bottom of the cooking cavity. The metal base plate has clearance openings corresponding to the protective ribs and support ribs. The protective ribs and support ribs pass through the clearance openings and protrude from the metal base plate.

[0024] In this design, the protective ribs and support ribs are integrally molded into the mounting bracket, allowing them to be installed together with the bracket as a single component on the base. This reduces installation difficulty, improves installation efficiency, and ensures more stable relative positions of the support ribs and protective ribs, minimizing positional deviations caused by assembly errors. It also guarantees stable support between the support ribs and the fryer assembly, as well as reliable engagement between the protective ribs and the limiting grooves. Furthermore, the mounting bracket is fixed to the base, with the support ribs and protective ribs protruding from the metal base plate through clearance openings. This eliminates the need for machining specific structures on the metal base plate; only clearance openings are needed at corresponding locations, reducing machining difficulty and saving costs. Additionally, it allows the protective ribs and support ribs to be made of a different material than the metal base plate, such as plastic, further reducing scratches between them and the fryer assembly. Since only the support ribs and protective ribs protrude from the metal base plate, while the rest of the base and mounting bracket lie below it, this minimizes the exposure of plastic components and prevents large-area deformation due to heat.

[0025] The protrusion height of the protective rib is lower than that of the elastic pin.

[0026] In this design, the height of the protective rib is lower than the height of the elastic pin. This ensures reliable engagement with the limiting groove, guarantees effective insertion and locking of the elastic pin and the insertion hole, and improves insertion stability and locking stability.

[0027] The outer shell has a metal cover inside, which encloses the cooking cavity. The outer end of the side wall of the metal cover is bent outwards towards the cooking cavity to form a support frame with the outer shell. The support frame is located on both sides of the fryer assembly.

[0028] In this design, the outer sidewalls of the metal cover bend to both sides at the opening, forming door frames on both sides of the opening. Since the support frames formed by the bending of the metal cover are not supported by the outer shell, they are more prone to deformation upon impact. The combination of protective ribs and limiting grooves reduces the lateral sway of the fryer assembly relative to the outer shell, thereby reducing the possibility of collisions between the fryer assembly and the side support frames. It also reduces the impact and compressive forces exerted by the fryer assembly on the support frames, achieving the goal of reducing the stress on the support frames and minimizing the possibility of deformation or damage due to excessive stress, thus ensuring a high yield rate and overall machine quality.

[0050] like Figure 1 , Figure 2 As shown, an air fryer includes an outer shell 1 with a cooking chamber 12 and an air fryer assembly 2. An opening 11 communicating with the cooking chamber 12 is provided on one side of the outer shell 1. The air fryer assembly 2 can be pushed and pulled into and out of the cooking chamber 12 through the opening 11. An upwardly protruding elastic pin 14 is provided at the bottom of the cooking chamber 12. A socket 24 is provided at the bottom of the air fryer assembly 2 corresponding to the elastic pin 14, allowing the elastic pin 14 to be inserted into the socket 24. A protective rib 15 is also provided at the bottom of the cooking chamber 12 near the elastic pin 14. A limiting groove 23 cooperating with the protective rib 15 is provided at the bottom of the air fryer assembly 2. The protective rib 15 extends along the pushing and pulling direction of the air fryer assembly 2, and in the pushing and pulling direction, the protective rib 15 covers the elastic pin 14.

[0051] It should be noted that, as Figure 10 As shown, the bottom of the cooking cavity 12 is provided with a base 18 and a metal base plate 133 located above the base 18. The elastic pin 14 can be disposed on the base 18, passing through the metal base plate 133 and protruding from the metal base plate 133, or the elastic pin 14 can be disposed on the metal base plate 133; this is not limited here. Preferably, a spring or other elastic element is provided below or inside the elastic pin 14 to allow the elastic pin 14 to float up and down. Further, as... Figure 6 As shown, the socket 24 has a guide slope 241 on the side facing the inside of the cooking cavity 12, so that when the fryer assembly 2 is pushed into the cooking cavity 12, the elastic pin 14 can be inserted into the socket 24 via the guide slope 241. At the same time, when the fryer assembly 2 is pulled out, the elastic pin 14 can be guided by the guide slope 241 to slide out of the socket 24, so that the user can pull out the fryer assembly 2 with less effort.

[0052] In this invention, by providing a protective rib 15 at the bottom of the cooking cavity 12, which engages with the limiting groove 23 on the fryer assembly 2, the lateral swaying of the fryer assembly 2 perpendicular to the insertion direction is stopped by the wall of the limiting groove 23 and the protective rib 15 when it is pushed into the cooking cavity 12. This reduces the swaying of the fryer assembly 2 and, when swaying occurs, transfers the force to the limiting groove 23 and the protective rib 15, thereby reducing the force on the elastic pin 14, ensuring its integrity, and reducing the possibility of breakage. Furthermore, the protective rib 15 is positioned adjacent to the elastic pin 14, making the engagement position of the protective rib 15 with the limiting groove 23, i.e., the limiting position of the fryer assembly 2, closer to the engagement position of the elastic pin 14 and the insertion hole 24. This more effectively prevents changes in the relative position of the elastic pin 14 and the insertion hole 24, thereby reducing the shear force on the elastic pin 14 during lateral relative movement.

[0053] Furthermore, after the protective rib 15 is inserted into the limiting groove 23, the portion of the protective rib 15 that is inserted into the limiting groove 23 in the length direction forms a protective area. The protective rib 15 covers the elastic pin 14 in the length direction, so that the elastic pin 14 is located in the protective area. This further improves the protective effect of the protective rib 15 on the elastic pin 14 when the fryer assembly 2 shakes laterally relative to the outer shell 1. It not only reduces the shaking of the fryer assembly 2, but also transfers the stopping force between the fryer assembly 2 and the outer shell 1 to the protective rib 15, which mainly bears the force, reducing the force on the elastic pin 14.

[0054] It should be noted that this utility model does not limit the number of protective ribs 15 and elastic pins 14. In a preferred embodiment, such as Figure 1 , Figure 2 As shown, there are two protective ribs 15 and two flexible pins 14. Further, as... Figure 1 As shown, two protective ribs 15 are arranged at intervals in a direction perpendicular to the push-pull direction of the fryer assembly 2, and an elastic pin 14 is disposed between the two protective ribs 15.

[0055] There are two elastic pins 14 and two protective ribs 15, both spaced apart along the insertion direction. This makes the limiting effect of the elastic pins 14 on the fryer assembly 2, as well as the limiting effect of the limiting grooves 23 and the protective ribs 15 on the fryer assembly 2, more stable and reliable. The two protective ribs 15 are spaced further apart, which not only allows them to limit the fryer assembly 2 closer to both ends, improving the limiting effect, but also evenly distributes the stopping force between the fryer assembly 2 and the outer shell 1 across the two protective ribs 15, making the force on the two protective ribs 15 more uniform. Furthermore, for the outer shell 1, the greater distance between the two protective ribs 15 also disperses the force, preventing stress concentration and damage. The two elastic pins 14 are closer together, which not only facilitates insertion and mating with the insertion holes 24, but also reduces machining errors to a certain extent, ensuring accurate alignment of the two insertion holes 24 and the elastic pins 14.

[0056] Specifically, such as Figure 1 As shown, a resilient pin 14 and a protective rib 15 can be considered as a set of mating components. Two sets of mating components are arranged on the left and right sides of the insertion direction of the fryer assembly 2. The distance between the two sets of mating components is L1, and the distance between the resilient pin 14 and the protective rib 15 in one set of mating components is L2, where L1 > L2. This ensures that the resilient pin 14 and the protective rib 15 in each set of mating components are arranged adjacent to each other.

[0057] As a preferred embodiment of this implementation, such as Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, the fryer assembly 2 includes a pot body 21 and a handle portion 22 disposed on the outside of the pot body 21, and a limiting groove 23 disposed on the handle portion 22.

[0058] Normally, the pot body 21 extends into the cooking cavity 12 and comes into direct contact with the high-temperature environment inside the cooking cavity 12, while the handle 22 is located outside the cooking cavity 12 and has a relatively lower temperature. Therefore, the pot body 21 is generally made of metal, and the handle 22 is made of plastic. The limiting groove 23 is machined into the handle 22. On the one hand, the processing of plastic is simpler, saving costs and improving processing efficiency. On the other hand, during cooking, the pot body 21 generates a high temperature, while the handle 22 has a relatively low temperature. Therefore, when the limiting groove 23 and the protective rib 15 work together, heat transfer is reduced, preventing the protective rib 15 from directly contacting the high-temperature pot body 21 and deforming due to heat.

[0059] Specifically, such as Figure 1 As shown, the height of the handle 22 is higher than the height of the pot body 21, so that the upper edge of the handle 22 is higher than the upper edge of the pot body 21, and the lower edge of the handle 22 is lower than the lower edge of the pot body 21. Simultaneously, the width of the handle 22 is also greater than the width of the pot body 21, so that the left and right sides of the handle 22 extend beyond the edge of the pot body 21. This allows the fryer assembly 2 to be pushed into the cooking chamber 12, with the pot body 21 located inside the cooking chamber 12. The handle 22 can then close the opening 11, preventing heat loss from the cooking chamber 12 and ensuring heating efficiency.

[0060] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the insertion hole 24 and the limiting groove 23 are both provided on the bottom wall of the handle part 22, and the limiting groove 23 extends along the push-pull direction to the inner edge of the handle part 22 (the side facing the inside of the cooking cavity 12) to form an insertion port.

[0061] Correspondingly, such as Figure 1 As shown, the resilient pin 14 and the protective rib 15 are located at the bottom of the cooking cavity 12 near the opening 11. Specifically, as... Figure 1 As shown, the bottom of the cooking cavity 12 has a mating platform 17 that protrudes outward from the side wall of the cooking cavity 12, and the elastic pin 14 and the protective rib 15 are both located on the mating platform 17.

[0062] As a preferred embodiment of this utility model, such as Figure 8 , Figure 9 As shown, in the pushing and pulling direction of the fryer assembly 2, the extension length of the limiting groove 23 is not less than the extension length of the protective rib 15.

[0063] After the protective rib 15 and the limiting groove 23 are inserted and matched, the protective rib 15 is completely contained within the limiting groove 23. On the one hand, this makes the connection between the two more stable and reliable, reducing the possibility that the protective rib 15 may come out of the limiting groove 23 due to shaking of the fryer assembly 2. On the other hand, the limiting groove 23 can also cooperate with the protective rib 15 to guide the pushing and pulling of the fryer assembly 2, limiting the direction of the user's pushing and pulling operation of the fryer assembly 2, improving the smoothness of operation and reducing jamming.

[0064] Preferably, such as Figure 6 As shown, the limiting groove 23 has an open end 231 and an insertion end 232 along the pushing and pulling direction of the fryer assembly 2. The groove walls on both sides of the open end 231 extend in opposite directions to form a guiding slope 233 at the open end 231.

[0065] The wall of the limiting groove 23 expands outward at the opening end 231, forming an open structure. This guides the engagement of the limiting groove 23 and the protective rib 15, as well as the insertion of the fryer assembly 2, making it easier to insert the protective rib 15 into the limiting groove 23 and reducing the sticking sensation when the fryer assembly 2 is pushed into the cooking cavity 12. Furthermore, the outwardly expanding groove wall corrects the position of the fryer assembly 2 during its insertion into the cooking cavity 12. Even if the user does not center the fryer assembly 2 at the opening 11 during insertion, but slightly offsets it, the limiting groove 23 contacts the guide slope 233 during insertion. The guide slope 233 guides the protective rib 15, allowing the fryer assembly 2 to complete lateral alignment during movement, ensuring it is inserted into the cooking cavity 12 in a centered position. This prevents increased resistance when pushing or pulling the fryer assembly 2 in an unequal position, improving the user experience.

[0066] Preferably, such as Figure 10 As shown, the outer casing 1 includes a base 18 located below the cooking cavity 12. A metal base plate 133 is provided at the bottom of the cooking cavity 12. The metal base plate 133 is provided with a clearance opening 1331 corresponding to the protective rib 15. The protective rib 15 passes through the clearance opening 1331 and protrudes from the metal base plate 133.

[0067] Preferably, the base 18 is made of plastic, and the protective rib 15 is disposed on the base 18, which simplifies the processing and assembly of the protective rib 15. It eliminates the need to process corresponding structures on the metal base plate 133; only a clearance opening 1331 needs to be processed at the corresponding position for the protective rib 15 to pass through, reducing the processing difficulty of the metal base plate 133 and saving costs. Furthermore, this allows the protective rib 15 to be made of a different material than the metal base plate 133, such as plastic, further reducing scratches between it and the fryer assembly 2. Moreover, among the plastic parts, only the protective rib 15 protrudes from the metal base plate 133, while the other areas of the base 18 are located below the metal base plate 133, reducing the exposure of plastic parts and preventing large areas of plastic parts from deforming due to heat.

[0068] Of course, in other embodiments, the protective rib 15 can also be provided on the metal base plate 133, for example, by making a local area of ​​the metal base plate 133 bulge upward to form the protective rib 15, or by fixing the individual protective rib 15 to the metal base plate 133, which is not limited here.

[0069] As a preferred embodiment of this utility model, such as Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 10 As shown, the bottom of the cooking cavity 12 is also provided with an upwardly protruding support rib 16. The support rib 16 extends along the pushing and pulling direction of the fryer assembly 2. The bottom of the fryer assembly 2 is isolated from the bottom wall of the cooking cavity 12 under the action of the support rib 16. The protrusion height of the protective rib 15 is lower than the protrusion height of the support rib 16.

[0070] Specifically, the upper edge of the protective rib 15 is lower than the upper edge of the supporting rib 16.

[0071] The support rib 16 contacts and supports the bottom of the fryer assembly 2, creating a gap between the fryer assembly 2 and the bottom wall of the cooking cavity 12 without direct contact. This prevents severe scratching of the coating on the bottom of the cooking cavity 12 and the bottom of the fryer assembly 2, thus preventing wear and tear and effectively extending the service life of the fryer assembly 2. Furthermore, the support rib 16 extends along the pushing and pulling direction of the fryer assembly 2, helping to guide its movement and making it easier and less strenuous to place and remove.

[0072] Furthermore, since the support rib 16 has a certain length, it can increase the contact area with the fryer assembly 2, which not only improves the support stability of the fryer assembly 2, but also makes it easier for the user to slide the fryer assembly 2 along the support rib 16, thus improving the user experience.

[0073] Specifically, such as Figure 1As shown, the fryer assembly 2 includes a pot body 21 and a handle portion 22 located on the outside of the pot body 21. When the fryer assembly 2 is pushed into the cooking chamber 12, the pot body 21 is located inside the cooking chamber 12, and the handle portion 22 is located outside the cooking chamber 12 and closes the opening 11. The support rib 16 can abut against the bottom of the pot body 21 to provide support for the fryer assembly 2.

[0074] Furthermore, such as Figure 1 , Figure 10 As shown, there are two support ribs 16, which are spaced apart in a direction perpendicular to the push-pull direction of the fryer assembly 2. The protective rib 15 is located between the two support ribs 16, and the protective rib 15 is positioned closer to the opening 11 relative to the support ribs 16.

[0075] The support rib 16 is positioned closer to the left and right ends of the fryer assembly 2. Therefore, when the fryer assembly 2 is pushed into the cooking cavity 12, the support rib 16 provides more stable support, preventing the fryer assembly 2 from tilting within the cooking cavity 12. Meanwhile, the protective rib 15 is closer to the opening 11, allowing it to work in conjunction with the limiting groove 23 to indicate when the fryer assembly 2 is fully inserted. Once the protective rib 15 stops against the rear wall of the limiting groove 23, it indicates that the fryer assembly 2 is fully inserted. At this point, the user receives clear force feedback and cannot push the fryer assembly 2 any further.

[0076] Preferably, such as Figure 7 , Figure 10 As shown, the air fryer also includes a mounting bracket 3, a protective rib 15 and a support rib 16 integrally formed on the mounting bracket 3 and protruding upwards, and the outer shell 1 includes a base 18 located below the cooking cavity 12. A metal base plate 133 is provided at the bottom of the cooking cavity 12. The metal base plate 133 is provided with a clearance opening 1331 corresponding to the protective rib 15 and the support rib 16. The protective rib 15 and the support rib 16 pass through the clearance opening 1331 and protrude from the metal base plate 133.

[0077] The protective rib 15 and the support rib 16 are integrally formed on the mounting bracket 3, so that the two and the mounting bracket 3 can be installed together on the base 18 as a component. This reduces the installation difficulty and improves the installation efficiency. It also makes the relative position of the support rib 16 and the protective rib 15 more stable, reduces the positional deviation caused by assembly error, ensures the stable support of the support rib 16 and the fryer assembly 2, and the reliable cooperation between the protective rib 15 and the limiting groove 23. Furthermore, the mounting bracket 3 is fixed to the base 18, and the support rib 16 and protective rib 15 protrude from the metal base plate 133 through the clearance opening 1331. This eliminates the need to process the corresponding structure on the metal base plate 133; only the clearance opening 1331 needs to be processed at the corresponding position, reducing the processing difficulty of the metal base plate 133 and saving costs. On the other hand, it allows the protective rib 15 and support rib 16 to be made of a different material than the metal base plate 133, such as plastic, further reducing scratches between them and the fryer assembly 2. Only the support rib 16 and protective rib 15 protrude from the metal base plate 133; the base 18 and other areas of the mounting bracket 3 are located below the metal base plate 133, reducing the exposure of plastic parts and preventing large-area plastic parts from deforming due to heat. Simultaneously, when assembling the metal base plate 133 and the base 18, the clearance opening 1331 and the cooperation of the support rib 16 and protective rib 15 can be used to form a positioning mechanism, ensuring accurate alignment and installation of the metal base plate 133 and the base 18. Further, as... Figure 10 As shown, the lengths of the support ribs 16 and the protective ribs 15 are different. The clearance opening 1331 is set one-to-one with each support rib 16 and protective rib 15 to play a foolproof role in the assembly process of the metal base plate 133 and the base 18, so that each protective rib 15 and support rib 16 can accurately match its corresponding clearance opening 1331.

[0078] like Figure 7 , Figure 10 , Figure 11 As shown, the mounting bracket 3 is provided with at least one downwardly extending insertion post 31, and the base 18 is provided with a mating post 181 corresponding to the insertion post 31. The insertion post 31 and the mating post 181 are inserted and engaged to pre-position the mounting bracket 3. The mounting bracket 3 is also provided with a snap-fit ​​part 32, and the base 18 is provided with a hook 182. The mounting bracket 3 and the base 18 are fixed by engaging the snap-fit ​​part 32 and the hook 182. Of course, the mounting bracket 3 can also be fixed to the base 18 in other ways, such as screw connection, etc., which is not limited here.

[0079] In a preferred embodiment, such as Figure 7 As shown, the support rib 16 has a structure in which the height gradually increases and then gradually decreases in the extension direction.

[0080] Preferably, the protrusion height of the protective rib 15 is lower than the protrusion height of the elastic pin 14. That is, the upper edge of the protective rib 15 is lower than the upper edge of the elastic pin 14 when it is not pressed down.

[0081] The height of the protective rib 15 is lower than the height of the elastic pin 14. While ensuring reliable cooperation with the limiting groove 23, it can ensure the effective insertion and locking of the elastic pin 14 and the insertion hole 24, and improve the insertion stability and ensure the locking stability.

[0082] In a preferred embodiment of this utility model, such as Figure 1 , Figure 3 As shown, a metal cover 13 is provided inside the outer shell 1, which forms a cooking cavity 12. The outer end of the side wall of the metal cover 13 is bent outward toward the cooking cavity 12 to form a support frame 131 with the outer shell 1. The support frame 131 is located on both sides of the fryer assembly 2.

[0083] The outer sidewalls of the metal cover 13 bend to both sides at the opening 11, forming door frames on both sides of the opening 11. Since the support frames 131 formed by the bending of the metal cover 13 are not supported by the outer shell 1, they are more prone to deformation upon impact. The cooperation of the protective ribs 15 and the limiting grooves 23 reduces the lateral swaying of the fryer assembly 2 relative to the outer shell 1, thereby reducing the possibility of collisions between the fryer assembly 2 and the fryer and the side support frames 131. It also reduces the impact and compressive forces exerted by the fryer assembly 2 on the support frames 131, achieving the goal of reducing the stress on the support frames 131, minimizing the possibility of excessive stress causing deformation or damage, and ensuring high yield and overall machine quality.

[0084] This embodiment does not limit the structure of the metal cover 13. In one embodiment, the top wall, side walls, and bottom wall of the metal cover 13 are all integrally formed to enclose the cooking cavity 12, thereby improving the sealing of the inner wall of the cooking cavity 12 and reducing heat leakage. In another embodiment, such as Figure 3 As shown, the metal cover 13 includes a side panel, a reflector 132 located above the side wall, and a metal base plate 133 located below the side wall. The reflector 132 and the metal base plate 133 are fixedly connected to the side panel by welding, screws, or other methods, so that the three form a cooking cavity 12. Manufacturing the metal cover 13 into three parts separately can reduce the manufacturing difficulty.
