[0030] Combined with the attached Figure 1 to the attached Figure 7 , the present application relates to an air fryer, which includes a base 1000, an inner shell 2000, and an outer shell 4000. The inner shell 2000 is arranged on the top of the base 1000, and the base 1000 is connected to the outer shell 4000. Specifically, the base 1000 is arranged in the outer shell 4000, and the outer shell 4000 covers the base 1000. Further, an electrical appliance chamber is formed between the top of the base 1000 and the top of the outer shell 4000, and the inner shell 2000 is located in the electrical appliance chamber. Combined with the attached Figure 1 and the attached Figure 2 , the air fryer includes a top cover 4100, and the top cover 4100 is arranged on the top of the outer shell 4000 to cover the top of the outer shell 4000.

[0031] The air fryer includes an electric heating component. The base 1000 is provided with a heating chamber 1100, and the heating chamber 1100 is close to the bottom of the base 1000. The electric heating component is arranged on the top of the heating chamber 1100, and the electric heating component creates a high-temperature environment for the heating chamber 1100. Specifically, the electric heating component includes a heating element 1200, the heating element 1200 is set as a resistance heating tube, the heating element 1200 is formed along a spiral curve, and the heating element 1200 is formed into a disc shape.

[0032] Combined with the attached Figure 2, The air fryer includes a food container 5000. The food container 5000 is set as a loading tray or a drawer, and the food container 5000 is placed into the heating chamber 1100 for high-temperature treatment. Further, the heating chamber 1100 forms an opening on the front side of the outer shell 4000, and the food container 5000 is loaded into the heating chamber 1100 from the front side. The food container 5000 has a handle.

[0033] Combined with the attached Figure 2 , The air fryer includes a main controller 2201, and the main controller 2201 is arranged in the inner shell 2000. Specifically, the main controller 2201 is fixedly arranged on the surface of the inner shell 2000. The main controller 2201 is connected to the visualization panel on the surface of the air fryer, and the user operates the visualization panel to set the parameters or modes of the air fryer. The main controller 2201 is connected to the electric heating component through a wire, and the user controls the electric heating component of the air fryer through the main controller 2201.

[0034] It should be noted that the terminal 1201 of the heating element 1200 is arranged on the top of the base 1000, and the terminal 1201 and the main controller 2201 are respectively located on the left and right sides of the top of the base 1000. Considering that the terminal 1201 also needs to be connected to a wire, in order to avoid the terminal 1201 and the main controller 2201 being on the same side and increasing the occupied space of the two in the air fryer, in this application, the terminal 1201 and the main controller 2201 are specifically arranged on the left and right sides to improve the space utilization rate.

[0035] The air fryer includes a driver 3100 and a heat dissipation fin 3201. The driver 3100 is fixedly arranged in the inner shell 2000, and the heat dissipation fin 3201 is arranged in the inner shell 2000. The heat dissipation fin 3201 is fixedly connected to the rotating shaft of the driver 3100. The inner shell 2000 is provided with a first chamber 2101, and the heat dissipation fin 3201 is located in the first chamber 2101.

[0036] The driver 3100 drives the heat dissipation fin 3201 to rotate, and the heat dissipation fin 3201 forms a flowing heat dissipation air flow, thereby reducing the temperature of the inner shell 2000 of the air fryer. It can be understood that the heating chamber 1100 is an independent chamber in the air fryer. Considering that the heating chamber 1100 generates a large amount of heat, in order to avoid damaging the components in the electrical chamber due to high temperature, the air fryer is provided with heat dissipation fins 3201 to dissipate heat from the components of the air fryer in the outer shell 4000.

[0037] The terminal 1201 and the main controller 2201 are respectively located on the left and right sides of the driver 3100, improving the space utilization rate. Further, combined with the attached Figure 6 , The highest point of the main controller 2201 is lower than the highest point of the driver 3100.

[0038] Combined with the attachedFigure 3 , attachment Figure 6 and attachment Figure 7 , the driver 3100 is located in the middle of the top of the base 1000, so that the driver 3100 is located in the middle of the electrical appliance chamber. In this case, the terminal block 1201 and the main controller 2201 are located on the left and right sides of the driver 3100, which can well reduce the occupied space.

[0039] As an implementation, in combination with attachment Figure 3 , the air fryer includes a motor drive module 2202, the motor drive module 2202 is fixedly arranged on the surface of the inner shell 2000, the motor drive module 2202 is connected to the main controller 2201 through a wire, and the motor drive module 2202 has a circuit board connected to the driver 3100.

[0040] Since the driver 3100 requires an independent circuit board, if the motor drive module 2202 and the main controller 2201 share a circuit board, the occupied space will be increased. Therefore, in order to reduce the occupied space in the air fryer and optimize the shape of the inner shell 2000, the main controller 2201 and the motor drive module 2202 are respectively arranged at different positions on the surface of the inner shell 2000, and the main controller 2201 and the motor drive module 2202 are adaptively arranged according to the shape of the inner shell 2000.

[0041] The main controller 2201 and the motor drive module 2202 are respectively arranged on different sides of the surface of the inner shell 2000, reasonably utilizing the area on the surface of the inner shell 2000 to avoid increasing the size of the inner shell 2000. Considering the large size of the main controller 2201 and the large area occupied by the main controller 2201 on the surface of the inner shell 2000, the motor drive module 2202 is arranged on the other side of the inner shell 2000 to avoid the main controller 2201 and avoid increasing the size of the inner shell 2000 for arranging the motor drive module 2202.

[0042] Furthermore, the motor drive module 2202 and the terminal block 1201 are located on the same side, or the motor drive module 2202 is on the surface of the inner shell 2000 and behind the driver 3100.

[0043] In some examples, the height of the air fryer does not exceed 200 mm, and the left and right widths do not exceed 320 mm.

[0044] As an implementation, in combination with attachment Figure 4 , the electric heating component includes a hot air blade 3202, the hot air blade 3202 is fixedly connected to the rotating shaft of the driver 3100, and the hot air blade 3202 is located in the heating chamber 1100, and the hot air blade 3202 is located above the heating element 1200.

[0045] Driven by the hot air blade 3202, a circulating air flow is formed in the heating chamber 1100, and the air flow in the heating chamber 1100 passes through the electric heating component from top to bottom, so that the electric heating component heats the air flow. On the other hand, the heated air flow flows from top to bottom and towards the surface of the food in the food container 5000, which helps to heat the food.

[0046] It should be noted that the heat dissipation blade 3201 and the hot air blade 3202 share the rotating shaft of a driver 3100. The driver 3100 drives the heat dissipation blade 3201 and the hot air blade 3202 simultaneously, with a compact structure and improved efficiency.

[0047] Furthermore, the driver 3100 includes a DC motor. In this application, the driver 3100 replaces the conventional AC motor with a DC motor. The DC motor is smaller in size and height, which is beneficial to reducing the size of the air fryer, manufacturing an air fryer with a smaller size and height, and improving portability.

[0048] It can be understood that the hot air blade 3202 is arranged in the heating chamber 1100, and the inner shell 2000 is provided with a first chamber 2101 for accommodating the heat dissipation blade 3201, which helps to reduce the occupied space of the rotating shaft of the driver 3100 in the air fryer, and further reduces the height of the air fryer.

[0049] As an implementation manner, the outer shell 4000 is provided with an exhaust port 4201 and an air inlet 4202. Under the action of the heat dissipation blade 3201, the cold air serving as the heat dissipation air flow enters from the air inlet 4202 and exits the outer shell 4000 from the exhaust port 4201.

[0050] Combined with the attached Figure 1 , the rear side wall of the outer shell 4000 is provided with an exhaust port 4201 and an air inlet 4202 for cold air to maintain the integrity of the remaining side walls of the outer shell 4000 and ensure the integrity and aesthetic appearance of the air fryer.

[0051] Furthermore, the rear side wall of the first chamber 2101 is provided with a first channel 2102 communicating with the exhaust port 4201. The heat dissipation air flow entering the outer shell 4000 enters the first chamber 2101 from the top of the first chamber 2101 and flows from the rear side of the first chamber 2101 to the exhaust port 4201. The rear side wall of the heating chamber 1100 is provided with a second channel 1101 communicating with the exhaust port 4201.

[0052] Considering the heat generation of the circuit board of the motor drive module 2202, the motor drive module 2202 is close to the air inlet 4202 of the rear side wall of the outer shell 4000, and the cold air can reduce the temperature of the motor drive module 2202.

[0053] To enhance the heat dissipation performance in the air fryer, air intake holes are also provided at the bottom of the air fryer. Specifically, the air fryer includes a base 6000, a pedestal 1000 is disposed on the base 6000, a housing 4000 is fixedly connected to the base 6000, and the base 6000 is provided with at least one air intake hole.

[0054] As an implementation, in combination with the attached Figure 5 , the air fryer includes a ventilation plate 4300, the ventilation plate 4300 is disposed on the rear side wall of the housing 4000, and the exhaust port 4201 and the air intake port 4202 on the rear side wall of the housing 4000 are disposed on the ventilation plate 4300. Air intake ports 4202 are respectively disposed on the left and right sides of the exhaust port 4201 on the ventilation plate 4300. The rear side wall of the housing 4000 has a window, and the ventilation plate 4300 is disposed in the window of the rear side wall of the housing 4000.

[0055] A hollow communication structure 4302 is disposed inside the ventilation plate 4300. The communication structure 4302 extends from the inside of the ventilation plate 4300 towards the pedestal 1000. Both the first channel 2102 and the second channel 1101 are communicated with the communication structure 4302, so as to realize the communication between the heating chamber 1100 and the first chamber 2101 at the exhaust port 4201. Further, the communication structure 4302 is set as a rectangular tube.

[0056] It can be understood that the ventilation plate 4300 is made of a heat-resistant material.

[0057] In some examples, the ventilation plate 4300 is provided with a grid shape, the grid in the middle serves as the exhaust port 4201, and the grids on both sides serve as the air intake ports 4202.

[0058] As an implementation, to make the air fryer more convenient for storage and portability, the air fryer can be placed upright in a reclined position. In this case, the rear side wall of the housing 4000 is provided with feet 4301 to support the rear side of the air fryer.

[0059] Further, in combination with the attached Figure 5 , at least two support structures are provided on the outer surface of the ventilation plate 4300. When the air fryer is placed in a reclined position, the rear side wall of the housing 4000 is supported by the support structures. Specifically, feet 4301 are respectively disposed on the left and right sides of the ventilation plate 4300.

[0060] To improve the stability of the air fryer when placed upright in a reclined position, the rear side wall of the housing 4000 is also provided with a detachable support structure. In actual use, the power cord of the air fryer can also be wound around the support structure on the rear side wall of the housing 4000, which is convenient for the storage of the power cord.

[0061] In the related art, an exhaust port is provided on the ventilation plate, an air inlet is provided on the outer shell, and an opening window for installing the ventilation plate is provided on the rear side wall of the outer shell. However, in order to provide the rear support feet 4301 for this air fryer, it is necessary to form the feet 4301 at the rear side of the air fryer. To reduce the processing of the outer shell 4000, the feet 4301 are specifically provided on the outer side wall of the ventilation plate 4300. At the same time, the air inlet 4202 on the rear side wall of the outer shell 4000 is provided on the ventilation plate 4300, further reducing the processing difficulty of the outer shell 4000.

[0062] The embodiments of the present application have been described in detail above in conjunction with the accompanying drawings. However, the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the spirit of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
