[0034] Meanwhile, in the embodiment, the second fan 150 is detachably connected with the driving shaft 131 of the driving mechanism 130, so that the second fan 150 can be detached from the driving shaft 131 for cleaning operation, that is, the second fan 150 can be cleaned outside the air fryer 100, so that the cleaning space of the second fan 150 is not limited by the internal space of the air fryer 100, the second fan 150 can have sufficient cleaning space, which reduces the limitation on cleaning tools and cleaning space, facilitates to improve the convenience of cleaning operation of the second fan 150, facilitates to improve the thoroughness of cleaning of the second fan 150, helps to reduce the cleaning difficulty of the user on the whole machine, and improves the cleaning efficiency of the whole machine.

[0035] Further, the air fryer 100 further comprises a frying barrel 180 for containing food materials, and the frying barrel 180 is located in the cooking cavity. In the embodiment, the protective cover 110 containing the heating assembly 120 is located between the first fan 140 and the second fan 150, that is, the protective cover 110 containing the heating assembly 120 is located on the side of the second fan 150 away from the frying barrel 180. Compared with the protective cover 110 containing the heating assembly 120 or the exposed heating assembly 120 being arranged on the side of the second fan 150 close to the frying barrel 180, such as the heating assembly 120 being arranged on the lower side of the second fan 150 and the frying barrel 180 being located on the lower side of the heating assembly 120, the pollution degree of the protective cover 110 containing the heating assembly 120 can be reduced, so that the cleaning frequency of the protective cover 110 can be reduced, the cleaning period of the protective cover 110 can be prolonged, and the maintenance time of the user can be reduced. Meanwhile, the appearance of the protective cover 110 is regular, neat and simple, compared with the irregular appearance of the heating assembly 120, the cleaning is facilitated, the thoroughness of cleaning is improved, the cleaning difficulty of the user on the whole machine is further reduced, and the cleaning efficiency of the whole machine is improved.

[0036] Therefore, the air fryer 100 provided by the embodiment of the present application changes the arrangement position of the heating assembly 120 and the second fan 150, arranges the heating assembly 120 on the side of the second fan 150 away from the frying barrel 180, reduces the pollution degree of the heating assembly 120 by oil stains, arranges the heating assembly 120 inside the protective cover 110, and shields and protects the heating assembly 120 by the protective cover 110, further reduces the possibility of the heating assembly 120 being polluted by oil stains, so that the heating assembly 120 still has high cleanliness under the protection of the protective cover 110 after the air fryer 100 is used for a long time, and the cleaning operation of the user on the heating assembly 120 is reduced. Since the protective cover 110 is located on the side of the second fan 150 away from the frying barrel 180, the pollution degree of the protective cover 110 is reduced, and since the appearance of the protective cover 110 is regular and neat, the cleaning operation is facilitated, and the cleaning difficulty is reduced. The second fan 150 and the driving shaft 131 are detachably connected, so that the second fan 150 and the driving shaft 131 can be detached and separated, and then the second fan 150 is cleaned outside the air fryer 100. Compared with the cleaning of the second fan 150 in the internal space of the air fryer 100, the use of some small cleaning tools to clean the second fan 150 is reduced, the limitation of cleaning tools and cleaning space is reduced, the convenience of the cleaning operation of the second fan 150 is improved, the cleaning difficulty of the second fan 150 is reduced, the cleaning efficiency and cleaning effect are improved, the cleaning difficulty of the user on the whole machine is reduced, the cleaning operation of the user is improved, and the user's satisfaction is improved.

[0037] As shown in Figure 2 , Figure 4 and Figure 5 , the driving mechanism 130 can include a driving part 132, and the driving part 132 has a driving shaft 131. The driving part 132 can be driven in at least one of the following ways, such as electric driving, liquid driving, gas driving, etc. Specifically, the driving part 132 can be a motor, and the motor includes the driving shaft 131. Specifically, the motor can be a direct current motor. The driving part 132 can be located on one side of the protective cover 110. For example, the driving part 132 and the first fan 140 are located on the same side of the protective cover 110, and the first fan 140 is located between the driving part 132 and the protective cover 110.

[0038] The first fan 140 can be a centrifugal fan, and the first fan 140 and the driving shaft 131 can be detachably connected, so that the first fan 140 and the driving shaft 131 can be detached and separated for maintenance and replacement of the first fan 140 or the driving part 132, thereby improving maintenance efficiency and saving replacement cost. Specifically, the first fan 140 and the driving shaft 131 can be detachably connected by at least one of a bolt structure, a magnetic attraction structure, a clamping structure, a mortise and tenon structure, and a plug-in structure. It can be understood that in some examples, the first fan 140 and the driving shaft 131 can be fixedly connected by welding, adhesive, or the like, or the first fan 140 and the driving shaft 131 can be an integral structure.

[0039] The first fan 140 is located between the driving part 132 of the driving mechanism 130 and the protective cover 110. The driving part 132 of the driving mechanism 130 is likely to overheat and malfunction after long-term operation. The first fan 140 can ventilate and dissipate heat for the driving part 132, thereby reducing the possibility of high-temperature malfunction of the driving part 132 and improving the service life of the driving part 132.

[0040] The second fan 150 can be a centrifugal fan, and the second fan 150 and the driving shaft 131 can be detachably connected by at least one of a bolt structure, a magnetic attraction structure, a clamping structure, a mortise and tenon structure, and a plug-in structure.

[0041] The heating assembly 120 can be a heating pipe. Specifically, the heating assembly 120 can be a disc-shaped heating pipe to increase the radiation area of the heating assembly 120 and improve the heating efficiency. It can be understood that the middle part of the disc-shaped heating pipe can be a hollow structure to facilitate the driving shaft 131 to pass through the heating assembly 120 without damaging the structure of the heating assembly 120. It can be understood that the heating assembly 120 can also be other heating structures, which are not limited in the present application.

[0042] The first fan 140 and the second fan 150 are power-connected with the driving shaft 131, so that the driving mechanism 130 can drive the first fan 140 and the second fan 150 to move simultaneously through one driving shaft 131. Compared with two driving shafts connected with the first fan 140 and the second fan 150 respectively, the arrangement of the driving shaft and the driving part is simplified, which is conducive to simplifying the structure, saving manufacturing cost, and meeting the design requirement of compact structure of the air fryer 100.

[0043] As shown in FIG. 1, the air fryer 100 comprises a protective cover 110, a heating assembly 120, a driving mechanism 130, a first fan 140, and a second fan 150. Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in some embodiments, the protective cover 110 includes a first cover 111 and a second cover 112 that are detachably connected and enclosed to form a receiving cavity, a heating assembly 120 is located inside the receiving cavity, and a drive shaft 131 passes through the first cover 111 and the second cover 112.

[0044] In this embodiment, the first cover 111 and the second cover 112 are detachably connected and enclosed to form a receiving cavity to accommodate the heating component 120. This facilitates the disassembly and separation of the first cover 111 and the second cover 112 to repair and replace the heating component 120 in the receiving cavity, thereby improving the repair efficiency of the heating component 120. Compared with replacing the entire heating component 120 and the protective cover 110 when the heating component 120 fails, this arrangement helps to save on replacement costs.

[0045] The first cover 111 and the second cover 112 can be detachably connected by at least one of the following structures: bolt structure, magnetic structure, snap-fit ​​structure, tenon and mortise structure, and plug-in structure.

[0046] The drive shaft 131 passes through the first cover 111 and the second cover 112 to facilitate the power connection between the drive shaft 131 and the first fan 140 and the second fan 150.

[0047] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the first cover 111 is located between the first fan 140 and the second cover 112, and the second cover 112 is located between the first cover 111 and the second fan 150, that is, the first cover 111 is located on the side of the second cover 112 away from the second fan 150. The arrangement of the first cover 111 can reduce the possibility that the heat generated by the heating component 120 is quickly carried away by the first fan 140, reduce the heat loss of the heating component 120, and improve the heat utilization rate.

[0048] By connecting the heating element 120 to the first cover 111, and after the first cover 111 and the second cover 112 are detached, the heating element 120 connected to the first cover 111 can be detached from the second cover 112. This allows for maintenance of the heating element 120 from the first cover 111, such as moving the first cover 111 with the heating element 120 connected to it outside the air fryer 100 to perform maintenance. This provides a larger maintenance space, reduces maintenance difficulty, and improves maintenance efficiency. In other words, the first cover 111 supports the heating element 120 and reduces the likelihood that the heat generated by the heating element 120 will be quickly carried away by the first fan 140.

[0049] The heating assembly 120 is detachably connected with the first cover body 111, so that the heating assembly 120 and the first cover body 111 can be detached and separated for maintenance and replacement, the maintenance efficiency is improved, and the replacement cost is saved. The heating assembly 120 and the first cover body 111 can be detachably connected through at least one of a bolt structure, a magnetic attraction structure, a clamping structure, a mortise and tenon structure, and a plug-in structure.

[0050] As shown in Figure 6 , the first cover body 111 is provided with a third avoiding hole 1114, so that the heating assembly 120 can be electrically connected with the electrical elements outside the protective cover 110 through the third avoiding hole 1114, and power is supplied to the heating assembly 120.

[0051] As shown in Figure 4 , Figure 5 , Figure 6 and Figure 7 , in some embodiments, the second cover body 112 is provided with a first mounting groove 1121 recessed towards the second fan 150, the first cover body 111 is connected with the second cover body 112 and covers the slot of the first mounting groove 1121 to enclose a containing cavity, the middle part of the first cover body 111 is provided with a second mounting groove 1111 recessed towards the second cover body 112, the second mounting groove 1111 is located inside the first mounting groove 1121, and at least part of the first fan 140 is contained in the second mounting groove 1111.

[0052] In the embodiment, the recess directions of the first mounting groove 1121 and the second mounting groove 1111 are the same, the second mounting groove 1111 recessed towards the second cover body 112 is arranged on the first cover body 111 to provide a containing space for the first fan 140, and at least part of the first fan 140 is contained in the second mounting groove 1111 to reduce the space occupied by the first fan 140, so as to meet the design requirement of compact structure of the air fryer 100. The first mounting groove 1121 with the same recess direction as the second mounting groove 1111 of the first cover body 111 is arranged on the second cover body 112, so that the containing cavity has enough space to contain the heating assembly 120, and meanwhile, the layout of the first cover body 111 and the second cover body 112 is compact, the space occupied by the protective cover 110 is reduced, the design requirement of compact structure of the air fryer 100 is met, the space of the cooking cavity is greatly increased, and the market competitiveness of the product is improved.

[0053] As shown in Figure 4 , Figure 5 , Figure 7 and Figure 8 , in some embodiments, a through hole 1122 is opened in the groove bottom of the first mounting groove 1121, the protective cover 110 further includes a heat-conducting disc 113 connected with the second cover body 112 and covering the through hole 1122, and the driving shaft 131 passes through the heat-conducting disc 113.

[0054] In this embodiment, the heat-conducting plate 113 covers the through hole 1122 at the bottom of the first mounting groove 1121, so that the heat-conducting plate 113 and the second fan 150 are arranged opposite each other. Thus, the heat generated by the heating component 120 is transferred through the heat-conducting plate 113, allowing the heat-conducting plate 113 to heat up quickly. When the second fan 150 is working, the circulating airflow passing through the heat-conducting plate 113 can quickly carry away the heat from the heat-conducting plate 113 and flow through the frying tub 180 to heat and cook the food. The design of the heat-conducting plate 113 helps to improve the thermal energy utilization rate of the heating component 120 and increase heating efficiency. In other words, the second cover 112 is used to support the heating component 120 and the heat-conducting plate 113; it can be understood that the second cover 112 also has the function of maintaining the temperature of the cooking chamber.

[0055] Specifically, the heat conduction plate 113 can be a metal heat conduction plate or a non-metal heat conduction plate. For example, the heat conduction plate can be made of aluminum alloy, stainless steel, aluminum, etc., or it can be made of graphite, microcrystalline glass, etc.

[0056] Among them, such as Figure 8 As shown, the heat conduction plate 113 has a planar structure. The planar structure has a relatively neat and regular appearance. In this way, when the side of the heat conduction plate 113 facing the second fan 150 is contaminated with oil, the planar structure of the heat conduction plate 113 is easier to clean, reducing the cleaning difficulty for users, improving cleaning efficiency and achieving a higher cleaning effect.

[0057] In the above embodiments, the heat-conducting plate 113 is located inside or outside the receiving cavity, such as... Figure 4 and Figure 5 As shown, the heat-conducting plate 113 can be connected to the second cover 112 from the inside of the receiving cavity to cover the through hole 1122, or the heat-conducting plate 113 can be connected to the second cover 112 from the outside of the receiving cavity to cover the through hole 1122.

[0058] The heat-conducting plate 113 and the second cover 112 can be detachably connected via at least one of the following methods: bolt structure, magnetic structure, snap-fit ​​structure, tenon and mortise structure, or plug-in structure. This configuration allows for the separation of the second cover 112 from the heat-conducting plate 113, enabling maintenance and replacement of both components, thus saving on replacement costs. It is understood that the heat-conducting plate 113 can also be bonded to the second cover 112 with adhesive, or it can be welded to the second cover.

[0059] In the case that the heat-conducting disc 113 is located outside the accommodating cavity and detachably connected with the second cover 112, the heat-conducting disc 113 and the second cover 112 can be detached from the outside of the protective cover 110, so as to facilitate the maintenance or replacement of the heat-conducting disc 113, and improve the maintenance and replacement efficiency of the heat-conducting disc 113.

[0060] As shown in Figure 6 and Figure 7 , the first cover 111 is provided with a fourth avoiding hole 1113, the heat-conducting disc 113 is provided with a first avoiding hole 1131, and the driving shaft 131 penetrates through the fourth avoiding hole 1113 and the first avoiding hole 1131 to penetrate through the protective cover 110.

[0061] In some embodiments, the groove bottom of the first mounting groove 1121 is provided as a heat-conducting member, and the groove bottom of the first mounting groove 1121 is provided as a planar structure and is provided with a second avoiding hole for avoiding the driving shaft 131.

[0062] In this embodiment, by providing the groove bottom of the first mounting groove 1121 as a heat-conducting member, the heat-conducting member can transfer the heat generated by the operation of the heating assembly 120, so that the heat-conducting member can be quickly heated. In the case that the second fan 150 is working, the circulating airflow flowing through the heat-conducting member can quickly take away the heat of the heat-conducting member and flow through the frying barrel 180 to heat and cook the food. The provision of the heat-conducting member is beneficial to improve the heat energy utilization rate of the heating assembly 120 and improve the heating efficiency. At the same time, this kind of setting simplifies the setting of the heat-conducting disc and further simplifies the assembly operation of the heat-conducting disc and the second cover, which is beneficial to improve the assembly efficiency of the air fryer 100.

[0063] By providing the groove bottom of the first mounting groove 1121 as a planar structure, the outer surface of the planar structure is relatively neat and regular. Therefore, when the side of the second cover 112 facing the second fan 150 is contaminated by oil stains, that is, when the groove bottom of the first mounting groove 1121 facing the second fan 150 is contaminated by oil stains, the groove bottom of the first mounting groove 1121 with a planar structure is relatively easy to clean, which reduces the cleaning difficulty of the user and is beneficial to improve the cleaning efficiency and has a high cleaning effect.

[0064] In the case that the first cover 111 is provided with a fourth avoiding hole 1113, the groove bottom of the first mounting groove 1121 is provided with a second avoiding hole, and the driving shaft 131 penetrates through the fourth avoiding hole 1113 and the second avoiding hole to penetrate through the protective cover 110.

[0065] As shown in Figure 6As shown, in some embodiments, the first cover 111 is provided with an air inlet 1112 which is in communication with the accommodating cavity. Thus, the first cover 111 can work to deliver cold air from the air inlet 1112 to the accommodating cavity, to ventilate and dissipate heat for the heating assembly 120 in the accommodating cavity, to reduce the possibility of overheating of the heating assembly 120 and failure, and to help prolong the service life of the heating assembly 120.

[0066] The third avoiding hole 1114 can be located at the circumferential side of the second mounting groove 1111, so that the heating assembly 120 will not occupy the space of the second mounting groove 1111 in the process of connecting with the electrical element outside the protective cover 110, and sufficient mounting space is left for the first fan 140 to achieve a compact layout.

[0067] The air inlet 1112 can be located at the circumferential side of the second mounting groove 1111, such as near the third avoiding hole 1114, to facilitate ventilation and heat dissipation for the heating assembly 120 and the electrical element connected with the heating assembly 120. It can be understood that in some examples, the air inlet 1112 can also be located at the groove bottom of the second mounting groove 1111. The number of air inlets 1112 can be one, two, three or other numbers.

[0068] In some embodiments, the second cover 112 is provided with an air outlet which is in communication with the accommodating cavity. Since the second cover 112 is adjacent to the second fan 150, the air heated by the heating assembly 120 in the accommodating cavity can be directly transmitted to the outside of the accommodating cavity and near the second fan 150 through the air outlet. Thus, the hot air can be transmitted to the frying bucket 180 to heat and cook the food by the working of the second fan 150. The arrangement of the air outlet enables the hot air heated by the heating assembly 120 in the accommodating cavity to be quickly and directly transmitted to the outside of the accommodating cavity, thereby helping to improve the heating efficiency, improve the utilization rate of heat energy, and have good heating effect.

[0069] The air outlet is located at the side of the accommodating cavity, which can effectively reduce the possibility of oil stains entering the inside of the accommodating cavity through the air outlet, thereby improving the cleanliness of the heating assembly 120.

[0070] Specifically, the air outlet can be located on the groove wall of the first mounting groove 1121, and the number of air outlets can be one, two or more.
