[0042] In this embodiment, a cold air passage 101 is formed between the outer wall of the outer pot 110 and the inner wall of the cooking body 100 .

[0043] In a specific usage environment, the fryer 120 or the stew pot 130 can be selected according to actual needs to meet different cooking needs. In this embodiment, the cooking device is an air fryer 120 for specific explanation.

[0044] A hot air duct 102 is formed between the frying pot 120 or the stew pot 130 and the outer pot 110 . Specifically, a hot air duct 102 is formed between the outer wall of the frying pot 120 or the stew pot 130 and the inner wall of the outer pot 110 .

[0045] A heating element 140 is disposed at the hot air duct 102 , and the airflow in the hot air duct 102 flows through the heating element 140 , that is, the heating element 140 is used to heat the airflow in the hot air duct 102 .

[0046] In the above solution, the heating element 140 is preferably a heating tube, and the heating element 140 is installed on the inner wall of the outer pot 110 in an annular shape as a whole, so that the fryer 120 or the stew pot 130 can be placed in the outer pot 110.

[0047] The cooking body 100 is provided with a fan assembly 200, and specifically, the fan assembly 200 includes a heat dissipation fan blade 210 and a heat circulation fan blade 220. The heat dissipation fan blade 210 is used to discharge the excess heat in the cold air duct 101; the heat circulation fan blade 220 is used to make the airflow in the hot air duct 102 circulate between the frying pot 120 and the hot air duct 102 or flow between the stew pot 130 and the outer pot 110.

[0048] Specifically, the heat dissipation blades 210 are arranged in the cold air duct 101, and the heat circulation blades 220 are arranged in the hot air duct 102; a driving member 300 is provided on the cooking body 100, and the driving member 300 is used to drive the heat dissipation blades 210 and the heat circulation blades 220 to rotate. Preferably, the driving member 300 is a driving motor, and the heat dissipation blades 210 and the heat circulation blades 220 are installed on the output shaft of the driving motor, and relatively, the heat circulation blades 220 are located above the heat dissipation blades 210, that is, the output shaft of the motor passes through the bottom wall of the outer pot 110, so that the heat dissipation blades 210 and the heat circulation blades 220 can be driven to rotate synchronously by the driving motor, so as to generate airflow in the cold air duct 101 or the hot air duct 102 relatively independently.

[0049] The cooking body 100 has a plurality of air inlets 103 at the bottom and a plurality of air outlets 104 on the side wall; the heat dissipation fan blades 210 guide the gas from the air inlets 103 and discharge part of the gas from the air outlets 104 along the cold air duct 101, that is, the airflow generated by the rotation of the heat dissipation fan blades 210 discharges part of the heat located on the cold air duct 101 and the outer wall of the outer pot 110 from the air outlets 104 to the outside of the air fryer 120.

The debris tray 190 is provided with a clamping hole (not marked in the figure), which is matched with the clamping portion 172. When the grill 180 and the debris tray 190 are both installed on the support 170, the grill 180 is located above the debris tray 190. The grill 180 not only increases the contact area between air and food, but also makes it easier for the debris tray 190 to collect food residues or grease.

[0057] In order to further improve the air circulation in the fryer 120, in the above technical solution, a gap is provided between the edge of the debris tray 190 and the fryer 120, so that the airflow in the fryer 120 can flow back to the air cover 160 along the path of the gap, the ventilation holes 122, and the guide holes 164, thereby forming a relatively closed or complete cycle, further improving the utilization rate of heat, and also allowing the airflow in the fryer 120 to circulate continuously, further reducing the occurrence of uneven heating of food.

[0058] During specific use, the driving member 300 drives the heat dissipation fan blades 210 and the heat circulation fan blades 220 to rotate synchronously. The air flow path generated by the heat dissipation fan blades 210 is the bottom of the cooking equipment, the cold air duct 101, and the air outlet 104, thereby discharging part of the heat located on the cold air duct 101 and the outer wall of the outer pot 110 from the air outlet 104 to the outside of the air fryer 120.

[0059] When a frying pan 120 is placed in the outer pot 110, the airflow path generated by the heat circulation fan blades 220 is the inside of the wind cover 160, the hot air duct 102, the heating element 140, the air inlet 121, the gap, the ventilation hole 122, the guide hole 164, and the inside of the wind cover 160, thereby forming a relatively closed or complete cycle; when a stew pot 130 is placed in the outer pot 110, the airflow path generated by the heat circulation fan blades 220 is the inside of the wind cover 160, the hot air duct 102, and the heating element 140, and the airflow continuously flows in the hot air duct 102 to increase the temperature of the stew pot 130.

[0060] It should be noted that in the solution of this embodiment, other internal structures of the cooking device and its corresponding control structure are existing technologies, and the detailed structure and principle will not be explained here.

[0061] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
