[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] according to Figures 1 to 6As shown, the present invention discloses an air fryer with bottom-heating and baking functions. The structure comprises a heating base 1 and a fryer body 2 mounted on the heating base 1. The fryer body 2 houses a heating chamber 3 for cooking food. An upper heating device 4 is mounted above the heating chamber 3 to provide heat from the top. A key feature of the present invention lies in the design of the heating base 1. The heating base 1 comprises a base body 5, on which a bracket 6 is mounted. A heating plate 7 is mounted on the bracket 6. The central portion of the heating plate 7 is recessed downward to form a heating portion 8, within which a lower heating device 9 is mounted. The lower heating device 9 is located below the heating chamber 3, heating and baking food from the bottom up, achieving more uniform heat distribution and a more comprehensive cooking effect. Furthermore, the edge of the heating plate 7 is provided with a downwardly curved flange 10, which is inserted into a first mounting slot 11 provided on the bracket 6. This ensures that the heating plate 7 is securely fixed to the bracket 6, preventing loosening or displacement during use. To effectively control the heat generated during operation and ensure safe heat dissipation, the base body 5 is provided with a first heat dissipation slot 12 and a second heat dissipation slot 13, respectively, for dissipating the heat accumulated during operation. This structure not only provides dual heating from the top and bottom, but also facilitates assembly and disassembly and has excellent heat dissipation performance.

[0030] The bracket 6 is provided with a positioning rib 14, and the heating plate 7 is provided with a positioning slot 15 corresponding to the positioning rib 14. By inserting the positioning rib 14 into the positioning slot 15, the heating plate 7 can be accurately positioned during installation, effectively preventing displacement or shaking of the heating plate 7 during operation, thereby improving heating stability and safety. In addition, the flange 10 is provided with multiple limiting tabs 16, which are inserted into corresponding slots 17 on the bracket 6.

[0031] The main body 2 of the fryer consists of an outer shell 19 and an inner shell 18 disposed within the outer shell 19. An upper fan 20 is installed between the outer shell 19 and the inner shell 18. The heating chamber 3 is disposed within the inner shell 18, providing a closed cooking space to prevent heat leakage and improve energy utilization efficiency. A lower fan 21 is disposed between the bracket 6 and the base body 5. The lower fan 21 cooperates with the upper fan 20 to ensure that the hot air in the heating chamber 3 is evenly distributed, thereby improving cooking efficiency and effect. The upper heating device 4 and the lower heating device 9 are both electric heating tubes, which are efficient heating elements that can quickly generate heat and transfer it to the surface of the food, achieving a uniform and rapid cooking effect. The dual heating structure allows food to be heated from both the top and bottom simultaneously, avoiding the problem of partial overcooking or undercooking of food caused by traditional one-way heating, thereby improving cooking quality.

[0032] In terms of the installation structure, a second installation groove 22 is also provided on the bracket 6, and the inner shell 18 is installed on the second installation groove 22 by plugging. A third installation groove 23 is also provided on the base body 5, and the outer shell 19 is plugged into the third installation groove 23, ensuring a firm connection between the outer shell 19 and the base body 5, making the entire air fryer structure tighter and firmer, thereby extending the service life of the equipment and improving the overall performance.

[0033] The bottom of the heating base 1 is first provided with an upwardly protruding first bump 24. Flanked by first heat dissipation grooves 12, heat is dissipated from both sides, preventing excessive heat accumulation during prolonged use and ensuring safe operation. Furthermore, the bottom of the heating base 1 is provided with a second bump, also protruding upward. Flanked by second heat dissipation grooves 13, the second bump is also provided with a second heat dissipation groove 13. The second bump is tilted at a 45° angle relative to the lower heating device 9. This angle facilitates rapid heat flow, effectively preventing heat accumulation at the bottom of the heating base 1 and further improving heat dissipation efficiency. The first bumps 24 are arranged in two rows at the center of the base body 5, and the second bumps are arranged around the first bumps 24, forming a surround structure. This allows the heating base 1 to better dissipate heat generated during operation, thereby improving the heat dissipation capacity and stability of the entire air fryer, helping to extend the life of the device and enhance its safety.

[0034] When assembling the present invention, first, the base body 5 needs to be placed on a stable work surface to ensure that it is stable. Next, the bracket 6 on the heating base 1 is fixed. The installation of the bracket 6 should ensure that it is firm, and the raised part is accurately aligned with the installation point on the base. Next, the user needs to connect the heating plate 7 to the bracket 6 through the flange 10. The limit piece 16 on the flange 10 needs to be accurately inserted into the slot 17 on the bracket 6. At the same time, the positioning rib 14 should be inserted into the positioning groove 15 of the heating plate 7 to ensure that the heating plate 7 will not be offset or loose during the installation process, ensuring the stability of the structure. After completing the installation of the heating plate 7, the user can start to assemble the main part of the fryer, inserting the inner shell 18 into the second installation groove 22 of the bracket 6, and inserting the outer shell 19 into the third installation groove 23 of the base body 5 to ensure that it is tightly combined with the base. During use, the upper and lower heating devices 4 and 9 operate simultaneously, heating the food evenly through the dual heating system at the top and bottom. Furthermore, the upper and lower fans 20 and 21 within the device circulate air, allowing the hot air to evenly cover all parts of the food, achieving fast and even cooking results. This air circulation allows the device to heat food to the ideal state in a short period of time, achieving a crispy surface and moist interior.

[0035] The beneficial effects brought by the utility model are:

[0036] The utility model adopts the dual heating design of the upper heating device and the lower heating device, which can heat food from the top and the bottom at the same time, ensuring that the food is heated evenly and improving the cooking effect.
