[0027] The present utility model will be further described in detail below with reference to the accompanying drawings.
[0028] Among them, the same parts are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.
[0029] As Figure 1 and Figure 2 shown, an air fryer with an independent centrifugal air duct heat dissipation structure includes a fuselage 1. A fan base 2 is arranged inside the fuselage 1. A partition lining 3 is arranged inside the fan base 2. Below the partition lining 3 is a cooking chamber 4, and above the partition lining 3 is a heat dissipation chamber 5. An air duct cover 6 is arranged on the top of the fan base 2. A heat dissipation air duct is formed by the cooperation between the air duct cover 6 and the partition lining 3. A motor 7 and a centrifugal fan blade 8 driven by the motor 7 are arranged in the heat dissipation chamber 5; the motor is an external rotor motor. The fan base 2 is provided with a heat dissipation air outlet 9 communicating with the heat dissipation air duct along the side wall. There is an exhaust port 10 on one side of the fuselage 1 communicating with the heat dissipation air outlet 9. The top of the air duct cover 6 is provided with an air intake through slot 11 communicating with the heat dissipation chamber 5.
[0030] The partition lining 3 can separate the cooking chamber 4 from the heat dissipation chamber 5, ensuring that the high temperature during the cooking process does not affect the electrical components. A duct cover 6 is provided on the fan base 2. The duct cover 6 and the partition lining 3 cooperate to form a heat dissipation duct. During use, air enters from the duct cover 6, and the air intake through groove 11 allows external air to enter the heat dissipation chamber 5 to provide the air required for cooling the electrical components. When the electrical components generate heat during operation, the cold air introduced through the air intake through groove 11 can help reduce the temperature in the heat dissipation chamber 5, thereby improving the heat dissipation efficiency. The centrifugal fan blade 8 rotates under the drive of the motor 7 to generate strong wind, accelerating the dissipation of heat. The heat can be discharged outside the body 1 through the heat dissipation air outlet 9 and the air guide grille 21, maintaining the temperature stability inside the air fryer. This design enables the heat to be effectively conducted and dissipated through the duct. The air forms air pressure through the centrifugal duct, and the strong and fast hot air blows out from the cavity, forming air convection to achieve rapid heat dissipation, ensuring the stable operation of the product. The design of the independent centrifugal duct helps reduce the noise during the operation of the fan. The low noise and the low temperature effect of the whole machine shell bring a better experience to customers. The heating fan and the heating tube enable the food to be quickly cooked under high temperature conditions.
[0031] A heat reflection plate 12 is provided under the partition lining 3. A heat dissipation slot 13 is provided inside the fan base 2 below the heat dissipation air outlet 9. The heat dissipation slot 13 is communicated with the air outlet 10. The design of the heat dissipation slot 13 enables the heat on the heat reflection plate 12 to be discharged more smoothly through the duct. The communication with the air outlet 10 further ensures the effective dissipation of heat, preventing the heat from accumulating inside the air fryer, thereby protecting the electrical components and extending the service life of the device.
[0032] The output shaft of the motor 7 passes through the partition lining 3 and the heat reflection plate 12 and is provided with a heating fan blade 14. A heating tube 15 is provided at the bottom of the heat reflection plate 12 outside the heating fan. The heating fan blade 14 is directly driven by the motor 7 and can quickly generate strong air flow. This air flow is heated when passing through the heating tube 15 to form high-temperature hot air. This design enables the heat to be transferred to the cooking chamber 4 faster, improving the heating efficiency. The rotation of the heating fan blade 14 causes the hot air to circulate in the cooking chamber 4, thereby achieving uniform distribution of heat.
[0033] A safety net plate 16 is provided under the partition lining 3 below the heating fan blade 14 and the heating tube 15. The safety net plate 16 can prevent users from being injured due to accidental contact during the process of taking and using, reducing the risk of scalding.
[0034] Several limit posts 17 are provided at the top of the fan base 2. A plurality of buckles 18 are arranged along the side wall of the air duct cover 6, and limit holes 19 for connecting the limit posts 17 are formed in the buckles 18. The cooperation between the limit posts 17 and the limit holes 19 ensures that the air duct cover 6 can be accurately positioned at the top of the fan base 2 during installation, avoiding deviation or shaking during the installation process, enhancing the structural stability, and being relatively convenient for disassembly and assembly. Just align the buckles 18 with the limit posts 17 at the top of the fan base 2 and gently press or lift the air duct cover 6. The tight fit between the limit posts 17 and the limit holes 19 reduces the gap between the air duct cover 6 and the fan base 2, preventing foreign objects from entering the interior. The stable structure can also effectively protect components such as the heating fan and heating tube inside the fan base 2 from external impact and damage, ensuring the normal operation of the device.
[0035] A motor seat 20 for placing the motor 7 is installed on the partition lining 3. A rotating shaft is arranged inside the motor 7. A centrifugal fan blade 8 is fixedly connected to the top of the rotating shaft, and a heating fan blade 14 is fixedly connected to the bottom of the rotating shaft. The motor seat 20 provides a stable support for the motor 7, making the motor 7 more stable and reliable during operation. The heating fan blade 14 is directly driven by the rotating shaft and can quickly transfer heat to the surrounding air to form high-temperature hot air. This design enables the heat to be transferred to the cooking chamber 4 faster, improving the heating efficiency.
[0036] As Figure 3 shown, an air outlet 10 for embedding the air guide grille 21 is provided inside the fuselage 1. A plurality of positioning holes 22 are formed at the top of the air guide grille 21, and positioning posts 23 for inserting the positioning holes 22 are arranged along the top of the air outlet on the fan base 2. The air guide grille 21 is installed by being embedded in the air outlet 10 and cooperating with the positioning posts 23, ensuring its stable position inside the fuselage 1. This design avoids loosening or displacement of the air guide grille 21 during use, thus ensuring the stability and consistency of air flow.

Those skilled in the art can make modifications to the embodiments without creative contributions according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
