Description
Technical Field
[0001] This utility model relates to the field of kitchen appliances, and in particular to a modular dual-core air fryer. Background Technology
[0002] As people's lives improve, their cooking methods are becoming more diverse. However, most existing air fryers are single-cavity structures with fixed cooking chambers, making it difficult to process different ingredients simultaneously and thus failing to meet users' diverse cooking needs. To address this, a type of dual-cavity air fryer has emerged on the market. This type of air fryer has multiple cavities and can cook different foods at the same time. However, due to its unreasonable cavity layout, it tends to occupy a large amount of kitchen space. Moreover, its low modularity makes it difficult to flexibly adjust the cooking space, resulting in higher production and operating costs as well as a poor user experience. Utility Model Content
[0003] This application provides a modular dual-core air fryer to solve the technical problems of existing air fryers, such as low cooking efficiency, high space occupation, high production and usage costs, and poor user experience.
[0004] To address the aforementioned technical problems, this utility model provides a modular dual-core air fryer, comprising a lower core assembly, a middle core assembly, an upper core assembly, and a cooking component. The lower core assembly includes a front-opening lower core and a base located below and fixedly connected to the bottom of the lower core. The rear sidewall of the lower core has a first hot air inlet and a second hot air inlet spaced vertically for hot air passage. A plurality of first connecting holes are provided on the sidewall of the lower core between the first and second hot air inlets, with first fasteners positioned within each hole. The middle core assembly is suspended within the lower core and has a first fixing hole for fixed connection with the first fasteners. The middle core assembly is adapted to form a [specific configuration / structure] with the lower core assembly. A second cooking chamber with a front opening; the upper core assembly is located above the lower core assembly and is fixedly connected to the top of the lower core assembly, the upper core assembly being adapted to form a first cooking chamber with a front opening together with the lower core assembly and the middle core assembly; a cooking component is located behind the lower core assembly and is fixedly connected to the lower core assembly, the cooking component including a first hot air circulation system and a second hot air circulation system capable of generating circulating airflow, the first hot air circulation system having a first air outlet extending upward and communicating with the upper part of the first cooking chamber and a first return air outlet corresponding to the first hot air outlet; the second hot air circulation system having a second air outlet extending upward and communicating with the upper part of the second cooking chamber and a second return air outlet corresponding to the second hot air outlet. This application divides the air fryer into several different components and connects these components to form the air fryer. This not only effectively improves the structural integrity of the air fryer but also effectively reduces the installation difficulty and production cost. At the same time, by using the separate lower core assembly, the middle core assembly, and the upper core assembly to form independent first and second cooking chambers, and configuring a dual hot air circulation system, it is possible to cook multiple foods simultaneously, effectively improving cooking efficiency. It also enables independent temperature control and efficient cooking in both chambers, thereby meeting the diverse cooking needs of users and effectively improving the user experience.
[0005] In an optional embodiment, the first hot air circulation system includes a first hot air circulation fan adapted to correspond to at least a portion of the first return air vent; the second hot air circulation system includes a second hot air circulation fan adapted to correspond to at least a portion of the second return air vent. By providing independent first and second hot air circulation fans for the first and second hot air circulation systems respectively, and corresponding the first and second hot air circulation fans to the first and second return air vents respectively, not only can the independence and controllability of the hot air output of the first and second cooking chambers be ensured, effectively improving cooking efficiency and cooking effect, but also the output hot air can be better returned to the first and second hot air circulation systems through the first and second return air vents, thereby improving the heat flow circulation efficiency within the first and second cooking chambers, and thus improving the cooking efficiency of the air fryer.
[0006] In an optional embodiment, a first airflow guide enclosure is provided around at least a portion of the first hot air circulation fan, and the first airflow guide enclosure has a first notch adapted to extend upward to form a first airflow channel connecting to the first air outlet; a second airflow guide enclosure is provided around at least a portion of the second hot air circulation fan, and the second airflow guide enclosure has a second notch adapted to extend upward to form a second airflow channel connecting to the second air outlet. By providing the first airflow guide enclosure, the second airflow guide enclosure, the first airflow channel, and the second airflow channel on the outside of the first and second hot air circulation fans respectively, not only can the airflow path within the first and second hot air circulation systems be optimized, thereby reducing the loss of circulating heat flow, but also the circulating heat flow generated by the first and second hot air circulation fans can be collected and concentratedly introduced into the first and second cooking chambers through the first and second airflow guide channels, thereby enhancing the concentrated output capacity of the first and second hot air circulation systems and improving the cooking efficiency of the air fryer.
[0007] In an optional embodiment, the upper core assembly includes an upper air duct plate adapted to be fixedly connected to the top of the lower core assembly. The upper air duct plate has a first air guide cavity in the middle that is recessed upward and opens downward, and the first air guide cavity is adapted to connect to the first air outlet. The middle core assembly includes a lower air duct plate, and the lower air duct plate has a second air guide cavity in the middle that is recessed upward and opens downward, and the second air guide cavity is adapted to connect to the second air outlet. By respectively providing the first air guide cavity and the second air guide cavity in the upper core assembly and the middle core assembly, the circulating heat flowing out of the first air outlet and the second air outlet can be dispersed and guided downward into the first cooking cavity and the second cooking cavity more evenly to heat the food in the first cooking cavity and the second cooking cavity. This not only avoids the situation where the food burns due to the circulating heat flow being blown directly into the first cooking cavity and the second cooking cavity, but also avoids the situation where the food is cooked differently due to the circulating heat flow being blown into the first cooking cavity and the second cooking cavity in a concentrated manner, effectively ensuring the cooking efficiency and cooking effect of the air fryer.
[0008] In an optional embodiment, the rear side of the first air guide cavity is provided with a first air inlet communicating with the first air outlet, the first air inlet extending into the first air outlet, the outer side of the first air outlet being provided with a plurality of first mounting holes, the upper core assembly being provided with a first positioning hole corresponding to the first mounting hole, and a second fastener being provided in the first mounting hole and the first positioning hole; the rear side of the second air guide cavity is provided with a second air inlet communicating with the second air outlet, the second air inlet extending into the second air outlet, the outer side of the second air outlet being provided with a plurality of second mounting holes, the middle core assembly being provided with a second positioning hole corresponding to the second mounting hole, and a third fastener being provided in the second mounting hole and the second positioning hole. By extending the first air inlet and the second air inlet into the first air outlet and the second air outlet respectively, the circulating hot air flowing out of the first air outlet and the second air outlet can be better guided into the first air guide cavity and the second air guide cavity, effectively improving the air guiding effect. Simultaneously, by setting a fastening structure on the outside of the first air outlet and the second air outlet, not only can the connection strength and stability of the upper core assembly, the middle core assembly, and the lower core assembly be improved, but the installation positioning of the upper core assembly and the middle core assembly can also be achieved, effectively reducing the installation difficulty of the upper core assembly and the middle core assembly, thereby reducing the production cost and user cost of the air fryer. Furthermore, by setting a fastening structure on the outside of the first air outlet and the second air outlet... By employing a fastening structure, the upper and middle core components can be consistently installed with the lower core component, ensuring that the first and second air outlets always correspond to the first and second air inlets. By adjusting the height of the lower core component, the capacity of the first and second cooking chambers can be changed without affecting the circulating heat flow path, thus adapting to the cooking needs of different users and different foods. This not only effectively improves the versatility of the upper and middle core components, enabling their application in products with similar structures to the air fryer, but also effectively reduces the design and molding costs of the air fryer at different capacities, thereby lowering the production and user costs of the air fryer.
[0009] In an optional embodiment, a first frying basket with a top opening is detachably provided in the first cooking cavity through a front opening, the top opening of the first frying basket being adapted to be located directly below the first air guide cavity, and a first ventilation hole communicating with the first hot air vent is provided at the lower part of the first frying basket; a second frying basket with a top opening is detachably provided in the second cooking cavity through a front opening, the top opening of the second frying basket being adapted to be located directly below the second air guide cavity, and a second ventilation hole communicating with the second hot air vent is provided at the lower part of the second frying basket. By detachably positioning the first and second frying baskets directly below the first and second air guide chambers, respectively, and by providing the first and second ventilation openings connecting the first and second hot air inlets at their lower portions, the circulating heat flow can be better dispersed and introduced into the first and second frying baskets and flow out through the first and second ventilation openings. This also ensures that the food in the first and second frying baskets is heated more evenly, effectively improving the food cooking efficiency and effect of the air fryer. Furthermore, the detachable design of the first and second frying baskets facilitates disassembly, cleaning, and replacement by the user, effectively enhancing the user convenience and experience of the air fryer.
[0010] In an optional embodiment, a protruding positioning post is provided on the rear side of the middle core assembly, and a positioning hole matching the positioning post is provided on the rear side wall of the lower core assembly. The positioning post and the positioning hole are adapted to position the middle core assembly during installation. By positioning the middle core assembly through the positioning post and the positioning hole, precise positioning and rapid installation of the middle core assembly can be achieved, effectively reducing the installation difficulty of the middle core assembly. At the same time, the positioning post and the positioning hole are also adapted to support and limit the middle core assembly. By supporting and limiting the middle core assembly through the positioning post and the positioning hole, not only can the connection stability between the middle core assembly and the lower core assembly be effectively improved, reducing the possibility of the middle core assembly shaking after connection, but also the connection strength between the middle core assembly and the lower core assembly can be effectively improved, reducing the possibility of connection failure or damage to the middle core assembly due to excessive weight of food in the second cooking cavity, effectively ensuring the performance stability and safety of the air fryer.
[0011] In one optional embodiment, the lower core has a concave cross-section with an open front, and the width and depth of the concave inner cavity are the same from top to bottom. This design not only simplifies the assembly process of the middle core assembly, allowing it to slide smoothly up and down within the concave inner cavity of the lower core to find a suitable assembly position, but also enhances the modularity of the air fryer. This means that to meet different cooking cavity capacity requirements, only the height of the lower core assembly and the installation height of the middle and upper core assemblies need to be changed, without requiring structural redesign. This effectively reduces the production and user costs of the air fryer.
[0012] In an optional embodiment, the lower movement has vertically extending guide portions on both sides of its front opening, and the middle movement assembly has guide grooves that match the guide portions. The middle movement assembly can slide up and down within the concave inner cavity of the lower movement along the guide portions via the guide grooves. The guide portions and guide grooves are adapted to guide and / or limit the installation of the middle movement assembly. By using the guide portions and guide grooves to guide and / or limit the installation of the middle movement assembly, the installation difficulty of the middle movement assembly can be effectively reduced, and the possibility of the middle movement assembly failing to connect with the lower movement or the connection easily failing due to improper installation can be reduced. This effectively ensures the connection strength and stability between the middle movement assembly and the lower movement.
[0013] In an optional embodiment, the air fryer further includes a housing assembly covering the upper core assembly, the lower core assembly, and the cooking assembly, wherein the housing assembly and the upper core assembly, the lower core assembly, and the cooking assembly are adapted to form a heat dissipation duct; a cooling fan system communicating with the heat dissipation duct is provided on the back of the first hot air circulation system and the second hot air circulation system; the housing assembly is provided with a first vent and a second vent corresponding to the upper core assembly and the cooling fan system, respectively, and the first vent and the second vent are respectively connected to the heat dissipation duct and the cooling fan system. By setting the heat dissipation duct between the outer shell assembly and the upper core assembly, the lower core assembly, and the cooking assembly, and connecting the heat dissipation duct to the cooling fan system, the cooling airflow generated by the cooling fan system can dissipate heat from the upper core assembly, the lower core assembly, and the cooking assembly. This not only effectively reduces the body temperature of the air fryer, ensuring the normal operation of the electrical components inside, but also reduces the risk of burns to the user due to excessively high body temperature, effectively improving user safety. Simultaneously, by setting the first and second vents to correspond to the upper core assembly and the cooling fan system respectively, external cold air entering the heat dissipation duct can contact the upper core assembly more quickly, thus dissipating heat from it. Furthermore, external cold air can be better drawn into the heat dissipation duct by the cooling fan system, thus dissipating heat from the air fryer, effectively improving the air fryer's heat dissipation efficiency and effect.
[0014] Compared with the prior art, the beneficial effects of this application are:
[0015] This application divides the air fryer into several different components and connects these components to form the air fryer. This not only effectively improves the structural integrity of the air fryer but also effectively reduces the installation difficulty and production cost. At the same time, by using the separate lower core assembly, the middle core assembly, and the upper core assembly to form independent first and second cooking chambers, and configuring a dual hot air circulation system, it is possible to cook multiple foods simultaneously, effectively improving cooking efficiency. It also enables independent temperature control and efficient cooking in both chambers, thereby meeting the diverse cooking needs of users and effectively improving the user experience.

[0026] Appendix Figure 1 To be continued Figure 4The diagram shows a modular dual-core air fryer provided by this utility model. The air fryer includes a lower core assembly 10, a middle core assembly 20, an upper core assembly 30, and a cooking component 40. The lower core assembly 10 includes a lower core 11 with an open front and a base 12 located below the lower core 11 and fixedly connected to its bottom. The rear side wall of the lower core 11 has a first hot air vent 111 and a second hot air vent 112 spaced vertically for hot air to pass through. A plurality of first connecting holes 13 are provided on the side wall of the lower core between the first and second hot air vents 111 and 112, with first fasteners limiting the connection within each hole. The middle core assembly 20 is suspended within the lower core 11 and has a first fixing hole 21 for fixed connection with the first fasteners. The middle core assembly 20 is adapted to form a front-to-back dual-core air fryer with the lower core 11. A second cooking chamber 114 with a side opening; the upper core assembly 30 is disposed above the lower core assembly 10 and fixedly connected to the top of the lower core assembly 11, the upper core assembly 30 being adapted to form a first cooking chamber 113 with a front opening together with the lower core assembly 10 and the middle core assembly 20; the cooking assembly 40 is disposed on the rear side of the lower core assembly 10 and fixedly connected to the lower core assembly 10, the cooking assembly 40 including a first hot air circulation system 41 and a second hot air circulation system 42 capable of generating circulating airflow, the first hot air circulation system 41 having a first air outlet 411 extending upward and communicating with the upper part of the first cooking chamber 113 and a first return air outlet 412 corresponding to the first hot air outlet 111; the second hot air circulation system 42 having a second air outlet 421 extending upward and communicating with the upper part of the second cooking chamber 114 and a second return air outlet 422 corresponding to the second hot air outlet 112.
[0027] like Figure 2As shown, when the air fryer is in use, the circulating hot air generated by the first hot air circulation system 41 enters the first cooking chamber 113 through the first air outlet 411, and flows back to the first hot air circulation system 41 via the first hot air outlet 111 and the first return air outlet 412; the circulating hot air generated by the second hot air circulation system 42 enters the second cooking chamber 114 through the second air outlet 421, and flows back to the second hot air circulation system 42 via the second hot air outlet 112 and the second return air outlet 422. By dividing the air fryer into several different components and connecting these components to form the air fryer, the structural integrity of the air fryer can be effectively improved, and the installation difficulty and production cost of the air fryer can also be effectively reduced. At the same time, by using the separate lower core assembly 10, the middle core assembly 20 and the upper core assembly 30 to form independent first cooking chamber 113 and second cooking chamber 114, and configuring a dual hot air circulation system, it is possible to cook multiple foods at the same time, effectively improving cooking efficiency. It is also possible to achieve independent temperature control and efficient cooking in both chambers, thereby meeting the diverse cooking needs of users and effectively improving the user experience.
[0028] like Figure 2 and Figure 3 As shown, in an optional embodiment, the first hot air circulation system 41 includes a first hot air circulation fan 413 adapted to correspond to at least a portion of the first return air vent 412; the second hot air circulation system 42 includes a second hot air circulation fan 423 adapted to correspond to at least a portion of the second return air vent 412. By providing independent first hot air circulation fans 413 and second hot air circulation fans 423 for the first hot air circulation system 41 and the second hot air circulation system 42 respectively, and by aligning the first hot air circulation fans 413 and second hot air circulation fans 423 with the first return air vent 412 and the second return air vent 422 respectively, not only can the independence and controllability of the hot air output of the first cooking chamber 113 and the second cooking chamber 114 be ensured, effectively improving cooking efficiency and cooking effect, but the output hot air can also be better returned to the first hot air circulation system 41 and the second hot air circulation system 42 through the first return air vent 412 and the second return air vent 422, thereby improving the heat flow circulation efficiency in the first cooking chamber 113 and the second cooking chamber 114, and thus improving the cooking efficiency of the air fryer.
[0029] like Figure 2 and Figure 3As shown, in an optional embodiment, a first airflow guide enclosure 414 is provided around at least a portion of the first heat circulation fan 413, and a first notch 415 is provided on the first airflow guide enclosure 414. The first notch 415 is adapted to extend upward to form a first airflow guide channel 416 communicating with the first air outlet 411; a second airflow guide enclosure 424 is provided around at least a portion of the second heat circulation fan 423, and a second notch 425 is provided on the second airflow guide enclosure 424. The second notch 425 is adapted to extend upward to form a second airflow guide channel 426 communicating with the second air outlet 421. By setting the first airflow guide 414, the second airflow guide 424, the first airflow guide channel 416, and the second airflow guide channel 426 on the outside of the first hot air circulation fan 413 and the second hot air circulation fan 423 respectively, not only can the airflow path within the first hot air circulation system 41 and the second hot air circulation system 42 be optimized, thereby reducing the loss of circulating heat flow, but also the circulating heat flow generated by the first hot air circulation fan 413 and the second hot air circulation fan 423 can be collected and concentratedly introduced into the first cooking cavity 113 and the second cooking cavity 114 through the first airflow guide channel 416 and the second airflow guide channel 426, thereby enhancing the concentrated output capability of the hot air from the first hot air circulation system 41 and the second hot air circulation system 42, and thus improving the cooking efficiency of the air fryer.
[0030] like Figure 2As shown, in an optional embodiment, the upper core assembly 30 includes an upper air duct plate 31, which is adapted to be fixedly connected to the top of the lower core 11. The upper air duct plate 31 has a first air guide cavity 311 that is recessed upward and opens downward in the middle, and the first air guide cavity 311 is adapted to communicate with the first air outlet 411. The middle core assembly 20 includes a lower air duct plate 22, which has a second air guide cavity 221 that is recessed upward and opens downward in the middle, and the second air guide cavity 221 is adapted to communicate with the second air outlet 421. By respectively setting the first air guide cavity 311 and the second air guide cavity 221 in the upper core assembly 30 and the middle core assembly 20, the circulating heat flow from the first air outlet 411 and the second air outlet 421 can be dispersed and introduced more evenly downwards into the first cooking cavity 113 and the second cooking cavity 114 to heat the food in the first cooking cavity 113 and the second cooking cavity 114. This not only avoids the situation where the food burns due to the circulating heat flow being blown directly into the first cooking cavity 113 and the second cooking cavity 114, but also avoids the situation where the food is cooked differently due to the circulating heat flow being blown into the first cooking cavity 113 and the second cooking cavity 114 in a concentrated manner, thus effectively ensuring the cooking efficiency and cooking effect of the air fryer.
[0031] like Figure 2As shown, in an optional embodiment, the first air guide cavity 311 has a first air inlet 312 connected to the first air outlet 411 on its rear side. The first air inlet 312 is adapted to extend into the first air outlet 411. The outer side of the first air outlet 411 has a plurality of first mounting holes. The upper core assembly 30 has a first positioning hole corresponding to the first mounting hole 5. The first mounting hole and the first positioning hole are provided with second fasteners. The second air guide cavity 311 has a second air inlet 222 connected to the second air outlet 421 on its rear side. The second air inlet 222 is adapted to extend into the second air outlet 421. The outer side of the second air outlet 421 has a plurality of second mounting holes. The middle core assembly 20 has a second positioning hole corresponding to the second mounting hole. The second mounting hole and the second positioning hole are provided with third fasteners. By extending the first air inlet 312 and the second air inlet 222 into the first air outlet 411 and the second air outlet 421 respectively, the circulating hot air flowing out of the first air outlet 411 and the second air outlet 421 can be better guided into the first air guide cavity 311 and the second air guide cavity 221, effectively improving the air guiding effect. Simultaneously, by setting a fastening structure on the outside of the first air outlet 411 and the second air outlet 421, not only can the connection strength and stability of the upper core assembly 30, the middle core assembly 20, and the lower core assembly 10 be improved, but the installation positioning of the upper core assembly 30 and the middle core assembly 20 can also be achieved, effectively reducing the installation difficulty of the upper core assembly 30 and the middle core assembly 20, thereby reducing the production cost and user cost of the air fryer. Furthermore, by extending the first air outlet 411 and the second air outlet 421... A fastening structure is provided on the outside of the air vent 421, which can also achieve constant installation of the upper core assembly 30 and the middle core assembly 20 with the lower core assembly 10. This ensures that the first air outlet 411 and the second air outlet 421 always correspond to the first air inlet 312 and the second air inlet 222. At this time, by adjusting the height of the lower core assembly 10, the capacity of the first cooking cavity 113 and the second cooking cavity 114 can be changed without affecting the circulating heat flow path, thereby adapting to the cooking needs of different users and different foods. This not only effectively improves the versatility of the upper core assembly 30 and the middle core assembly 20, allowing them to be applied to products with similar structures to the air fryer, but also effectively reduces the design and mold costs of the air fryer at different capacities, thereby reducing the production cost and user cost of the air fryer.
[0032] like Figure 2As shown, in an optional embodiment, a first frying basket 50 with a top opening is detachably provided in the first cooking cavity 113 through a front opening. The top opening of the first frying basket 50 is adapted to be located directly below the first air guide cavity 311. The lower part of the first frying basket 50 is provided with a first ventilation hole 51 communicating with the first hot air vent 111. A second frying basket 60 with a top opening is detachably provided in the second cooking cavity 114 through a front opening. The top opening of the second frying basket 60 is adapted to be located directly below the second air guide cavity 221. The lower part of the second frying basket 60 is provided with a second ventilation hole 61 communicating with the second hot air vent 112. By detachably positioning the first frying basket 50 and the second frying basket 60 directly below the first air guide cavity 111 and the second air guide cavity 112, and by providing the first ventilation opening 51 and the second ventilation opening 61, respectively, connecting the first hot air outlet 111 and the second hot air outlet 112, the circulating heat flow can be better dispersed and introduced into the first frying basket 50 and the second frying basket 60 and flow out from the first ventilation opening 51 and the second ventilation opening 61. This also ensures that the food in the first frying basket 50 and the second frying basket 60 is heated more evenly, effectively improving the food cooking efficiency and cooking effect of the air fryer. At the same time, the detachable design of the first frying basket 50 and the second frying basket 60 also facilitates user disassembly, cleaning, and replacement, effectively improving the user convenience and user experience of the air fryer.
[0033] In an optional embodiment, the middle movement assembly 20 has a protruding positioning post on its rear side, and the lower movement 11 has a positioning hole on its rear side wall that matches the positioning post. The positioning posts and positioning holes are adapted to position the middle core assembly 20 during installation. Positioning the middle core assembly 20 using these posts and holes enables precise positioning and rapid installation, effectively reducing installation difficulty. Simultaneously, the positioning posts and holes also provide support and limit for the middle core assembly 20. This not only improves the connection stability between the middle core assembly 20 and the lower core assembly 11, reducing shaking after connection, but also enhances the connection strength, minimizing the possibility of connection failure or damage due to excessive food weight in the second cooking cavity 114. This effectively ensures the performance stability and safety of the air fryer.
[0034] like Figure 3 and Figure 4As shown, in an optional embodiment, the lower core 11 has a concave cross-section with an open front, and the width and depth of the concave inner cavity of the lower core 11 are the same from top to bottom. This arrangement not only simplifies the assembly process of the middle core assembly 20, allowing it to slide smoothly up and down within the concave inner cavity of the lower core 11 to find a suitable assembly position, but also enhances the modularity of the air fryer. When the air fryer meets different cooking cavity capacity requirements, only the height of the lower core assembly 10 and the installation height of the middle core assembly 20 and the upper core assembly 30 need to be changed, without requiring structural redesign. This effectively reduces the production cost and user operating cost of the air fryer.
[0035] like Figure 3 and Figure 4 As shown, in an optional embodiment, the lower movement 11 has vertically extending guide portions 14 on both sides of the front opening, and the middle movement assembly 20 has a guide groove 23 that matches the guide portion 14. The middle movement assembly 20 can slide up and down in the concave inner cavity of the lower movement 11 along the guide portion 14 through the guide groove 23. The guide portion 14 and the guide groove 23 are adapted to guide the installation of the middle movement assembly 20. By guiding the installation of the middle movement assembly 20 through the guide portion 14 and the guide groove 23, the middle movement assembly 20 can slide up and down better within the concave inner cavity of the lower movement 11, thereby finding a suitable installation position and effectively reducing the installation difficulty of the middle movement assembly 20. At the same time, the guide portion 14 and the guide groove 23 are adapted to limit the installation of the middle movement assembly 20. By limiting the installation of the middle movement assembly 20 through the guide portion 14 and the guide groove 23, not only can the middle movement assembly 20 be reduced to shake randomly during installation, but also the situation where the middle movement assembly 20 cannot be connected to the lower movement 11 or the connection is prone to failure due to improper installation can be effectively guaranteed to ensure the connection strength and connection stability between the middle movement assembly 20 and the lower movement 11.
[0036] like Figures 1 to 4As shown, in an optional embodiment, the air fryer further includes a housing assembly 70 covering the upper core assembly 30, the lower core assembly 10, and the cooking assembly 40. The housing assembly 70 is adapted to form a heat dissipation duct 80 with the upper core assembly 30, the lower core assembly 10, and the cooking assembly 40. The back of the first hot air circulation system 41 and the second hot air circulation system 42 are provided with a cooling fan system 43 communicating with the heat dissipation duct 80. The housing assembly 70 is provided with a first vent 71 and a second vent 72 corresponding to the upper core assembly 30 and the cooling fan system 43, respectively. The first vent 71 and the second vent 72 are respectively connected to the heat dissipation duct 80 and the cooling fan system 43. When the air fryer is in use, the cooling fan system 43 is adapted to draw external cold air into the cooling duct 80 through the first vent 71 and the second vent 72 to form a cooling airflow. By setting the cooling duct 80 between the outer shell assembly 70 and the upper core assembly 30, the lower core assembly 10 and the cooking assembly 40, and connecting the cooling duct 80 to the cooling fan system 43, the cooling airflow generated by the cooling fan system 43 can be used to dissipate heat from the upper core assembly 30, the lower core assembly 10 and the cooking assembly 40. This not only effectively reduces the body temperature of the air fryer, but also ensures the stability of the control circuit and control system within the air fryer. Ensuring the normal operation of electrical components such as the control system can reduce the risk of burns to users due to excessively high temperatures in the air fryer, effectively improving user safety. Furthermore, by setting the first vent 71 and the second vent 72 to correspond to the upper core assembly 30 and the cooling fan system 43 respectively, external cold air entering the cooling duct 80 can contact the upper core assembly 30 more quickly, thus dissipating heat from it. Additionally, external cold air can be better drawn into the cooling duct 80 by the cooling fan system 43, thereby dissipating heat from the air fryer, effectively improving the air fryer's heat dissipation efficiency and effect.
