[0003] In the prior art, the hot air system is usually arranged at the top of the heating chamber, and the heating component in the hot air system is located below the fan. The hot air system drives the air in the main body to form an airflow, which is directly blown to the heating chamber after passing through the heating component to process the food in the heating chamber. In the arrangement of the hot air system, the heating component is arranged as a coil pipe, and the fan is located on one side of the coil pipe, that is, the airflow is transported from one side of the coil pipe to the other side. Therefore, for a unit flow of airflow, only one coil pipe is used for heating, and the heating efficiency is limited. Multiple airflow circulation is required to obtain hot airflow with a relatively high temperature.

[0004] However, the air fryer of upper and lower layers in the prior art usually only has one hot air system, which drives and supplies hot air to the two pot bodies. The cooking cavities of the two pot bodies need to be connected, and due to the difference in the relative positions between the two pot bodies and the hot air system, the pot body far from the hot air system receives less hot air and has a lower temperature, which affects the cooking effect of the food.

[0005] The connection between the two pot bodies requires that the hot air can enter any pot body. Therefore, there is no sealed chamber in the main body, and the hot air will also enter other spaces, causing overheating damage to the components in the main body. UTILITY MODEL CONTENTS

[0054] The assembly ribs are long strip-shaped protrusions arranged on both sides of the bottom of the top cover 123.

[0055] When the top cover 123 is assembled to the top shell, the assembly ribs are embedded into the assembly grooves 122.3, and the lower end faces of the two sides of the top cover 123 are tightly fitted on the assembly ribs 122.4, thereby ensuring the sealing of the inner shell assembly 120 and preventing the internal airflow from overflowing to the outside of the inner shell assembly 120 through the assembly gap.

[0056] Specifically, the back shell 130 is provided with an airflow driving groove 131 corresponding to the cooking chamber 121, and an air deflector 140 is arranged between the inner shell assembly 120 and the back shell 130 to separate the airflow driving groove 131 and the cooking chamber.

[0057] The air deflector 140 is provided with an air deflector area communicating with the cooking chamber.

[0058] In this embodiment, the air deflector 140 is arranged inside the inner shell assembly 120 close to the back shell 130, or on the rear end face of the bottom shell 122, and the air deflector area is located at the middle part of the air deflector 140, so that the airflow can flow between the cooking chamber 121 and the airflow driving groove 131.

[0059] Preferably, in this embodiment, the air deflector area is an air outlet groove 141 arranged in a concentric circle.

[0060] In this embodiment, in order to increase the airflow heating efficiency, an airflow driving assembly 400 is arranged in the airflow driving groove 131, which includes a heating component 150 and an airflow driving component 160 arranged along the airflow moving direction.
