The frying barrel 2 is used for forming a cooking space so as to empty fry the food materials 6, a plurality of vent holes communicated with the mounting cavity are formed in the frying barrel 2, and hot air heated in the mounting cavity can enter the frying barrel 2 and return to the mounting cavity after heating the food materials 6 through the vent holes; when in use, the frying barrel 2 can be placed in the accommodating cavity 142 from the opening of the accommodating cavity 142. After use, fry vat 2 can be removed from holding cavity 142 for cleaning. The hot air heating module 3 is installed in the installation cavity and includes a heating device 32 for heating air, a heating fan 34 for circulating air, and a motor 36 for driving the heating fan 34 to rotate. Meanwhile, the electric control board 4 is arranged in the pan body assembly 14. The electric control board 4 is used for comprehensively controlling the work of the air fryer.

The air fryer provided by the utility model comprises a shell assembly 1, a ground frying barrel 2 capable of being taken and placed, and a hot air heating module 3 for generating circulating hot air to heat food materials 6 in the frying barrel 2, wherein an electric control board 4 is used for controlling the operation of a motor 36 and a heating device 32 to control the heating of the food materials 6. Electric control board 4 is arranged in pan body assembly 14. This kind of structure, owing to install motor 36, hot-blast heating module 3 such as heating fan 34 and heating device 32 and automatically controlled board 4 on pot body subassembly 14, the part of placing on epitheca subassembly 12 has been reduced, just so the thickness of epitheca subassembly 12 has been attenuate, thereby can set up visual window on epitheca subassembly 12, so that the user when frying a pot culinary art through the air and eating material 6, can see through visual window and observe the state of eating material 6 in frying bucket 2, thereby be convenient for the user to know the culinary art progress of eating material 6 at any time, user's use satisfaction has been improved.

In the above embodiment, the upper shell assembly 12 has a two-layer structure, i.e., an inner shell 122 and an outer shell 124 provided with a window 1242, and meanwhile, a visual cover 126 is installed at the window 1242, a portion of the inner shell 122 corresponding to the window 1242 is a visual structure, and another portion of the inner shell 122 not corresponding to the window 1242 is a non-visual structure. Further, the visualization cover 126 and the visualization portion of the inner housing 122 are made of a transparent or translucent material.

In this embodiment, the upper housing assembly 12 includes a two-layer structure of an inner housing 122 and an outer housing 124, and a receiving space is formed between the inner housing 122 and the outer housing 124 by this arrangement, so as to facilitate mounting of components such as the electronic control board 4 on the upper housing assembly 12. And the inner shell 122 is made of transparent material or semitransparent material, so that the visualization of the whole inner shell 122 is realized. By providing the window 1242 on the housing 124 and installing the visual cover 126 at the window 1242, the user can observe the cooking state of the food material 6 through the visual cover 126. While the part of the inner shell 122 corresponding to the window 1242 is a visual structure, and the other part of the inner shell 122 not corresponding to the window 1242 is a non-visual structure, that is, the inner shell 122 is not a complete visual structure, and during design, the non-visual part of the inner shell 122 may be set to be a metal structure, a plastic structure, or the like, so as to conveniently set some additional installation structures at the non-visual part of the inner shell 122. On the other hand, if the inner shell 122 is completely visualized, it is very inconvenient to mount the inner shell 122 on the pot body assembly 14 because the secondary processing efficiency of the visualized plate material is low, and thus other structures cannot be additionally mounted on the inner shell 122. In addition, partial visualization of the inner shell 122 may also increase the strength of the entire inner shell 122, reducing the cost of the inner shell 122.

Further, the part of the inner shell 122 that needs to be visualized is provided with a windowing structure, and a cover plate made of transparent or semitransparent material is installed at the windowing structure and can be detachably installed on the inner shell 122.

In this embodiment, when cleaning is needed, the cover plate on the inner shell 122 and the visual cover plate on the outer shell can be detached for individual cleaning, instead of cleaning the entire upper shell assembly 12, which reduces the difficulty of cleaning and improves the user experience.

In the above embodiments, as shown in fig. 1, the pan body assembly 14 includes the inner pan body 144 and the outer shell 146, and a gap is further provided between the inner pan body 144 and the outer shell 146, the gap forms a first cavity, and the motor 36 and the like can be installed in the gap formed between the inner pan body 144 and the outer shell 146. Meanwhile, the fan cover 38 can be installed on the bottom wall of the inner pot body 144 to form a second cavity at the bottom of the inner pot body 144, and the heating device 32 and the heating fan 34 can be installed between the fan cover 38 and the inner pot body 144. When the food material 6 is heated, the motor 36 can drive the heating fan 34 to rotate, so that the air heated by the heating device 32 can flow circularly under the driving of the heating fan 34, and the food material 6 can be heated by continuous circulation of hot air. This arrangement realizes the divisional mounting of the motor 36 and the heating device 32, reduces the influence of the heating device 32 on the motor 36, and avoids overheating of the motor 36. And the fan cover 38 makes the frying barrel 2 taken out, the heating device 32 can not be directly exposed outside, thus the heating device 32 can be protected, and the user can be prevented from being scalded by mistakenly touching the heating device 32.

Further, as shown in FIG. 1, the motor 36 is mounted at a middle position of the bottom of the inner pot 144. This allows the motor 36 and the heating fan 34 to be directly connected, thereby reducing the transmission structure between the two. Further, the heating fan 34 is directly driven by the motor 36.
