[0006] By adopting the above technical solution, the air flow driving device drives the two wind wheel assemblies to rotate, and guides the air flow into the heating chamber to be heated into hot air by the heating element. The hot air is used to heat the food in the heating chambers in the upper cooking layer and the lower cooking layer at the same time, and the two heating chambers are isolated from each other, which can effectively prevent the heating chambers of the upper and lower cooking layers from mixing flavors when cooking food. After the hot air in the heating chamber heats the food, it flows out through the air duct chamber to realize the circulation of air flow. In addition, the utility model arranges the heating element and the wind wheel assembly at the same horizontal position, so that the air flow is directly blown onto the corresponding heating elements of the upper cooking layer and the lower cooking layer through the guiding effect of the wind wheel assembly. The utility model is conducive to reducing the flow rate loss of the air flow in the process of entering the heating chamber, so that the air flow can maintain a high flow rate and blow directly to the heating element to achieve heating and temperature rise. At the same time, the wind wheel assembly of the utility model can blow air laterally to the heating element at the same horizontal position, so that the generated hot air can better circulate hot air at a high flow rate in the heating chamber. At the same time, it can also effectively reduce the impact noise of the air flow on the heating chamber, effectively improve the heat generation rate in the heating chamber and the heating efficiency of the air fryer on the surface of the food, which has the advantages of effectively improving the heating and cooking efficiency, reducing noise, using double pots to increase the cooking capacity, and preventing the upper and lower cooking layers from mixing flavors during cooking.

[0012] By adopting the above technical solution, the cold air impeller and the hot air impeller cooperate to pass a part of the cold air in the cold air channel into the interior of the air duct chamber through the through hole, and then the hot air is blown from the upper part of the air duct chamber into the heating chamber by the hot air impeller, and finally the hot air is discharged from the air outlet. At the same time, the cold air impeller discharges the other part of the cold air remaining in the cold air channel from the air outlet. At this time, the hot air and cold air discharged from the air outlet mix with each other, reducing the outlet air temperature, which can effectively prevent burns at the air outlet position.

The air flow driving device drives the two wind wheel assemblies to rotate, and guides the air flow into the heating chamber and is heated into hot air by the heating element. The hot air is used to heat the food in the heating chambers of the upper cooking layer and the lower cooking layer at the same time, and the two heating chambers are isolated from each other, which can effectively prevent the heating chambers of the upper and lower cooking layers from mixing flavors when cooking food. The hot air in the heating chamber heats the food and then flows out through the air duct chamber to realize air circulation. In addition, the utility model arranges the heating element and the wind wheel assembly at the same horizontal position, so that the air flow is blown straight through the guiding effect of the wind wheel assembly. On the heating elements corresponding to the upper cooking layer and the lower cooking layer, it is beneficial to reduce the flow rate loss during the process of the air flow entering the heating chamber, so that the air flow can maintain a high flow rate and blow directly to the heating elements to achieve heating and temperature rise.

[0036] like Figure 2-4As shown, a first partition 11 is provided between the heating chamber 1a and the air duct chamber 1b. The first partition 11 is provided with an air hole 11a connecting the air duct chamber 1b and the heating chamber 1a, and an air inlet gap 11b is formed between the upper end of the first partition 11 and the fuselage main body 1.

The heating element 3 is configured as a spiral heating element. The heating tube is laid flat on the upper part of the heating chamber 1a and aligned with the air inlet gap 11b. The spirally arranged heating tube enables the heating element 3 to achieve a larger area of heat exchange with the air flow within a unit volume, thereby effectively improving the heating efficiency of the heating element 3 on the air flow; the fuselage body 1 is provided with a second partition 12, the wind wheel assembly 21 includes a cold air impeller 211 and a hot air impeller 212 respectively arranged on both sides of the second partition 12, the fuselage body 1 is provided with a cold air channel 1c and an air outlet 1d, the cold air channel 1c and the air duct chamber 1b The air outlet ends are connected to the air outlet 1d, the cold air impeller 211 is arranged in the cold air channel 1c, and the hot air impeller 212 is arranged in the air duct chamber 1b. The second partition 12 is provided with a through hole 12a connecting the cold air channel 1c and the air duct chamber 1b. The cold air impeller 211 and the hot air impeller 212 cooperate to pass a part of the cold air in the cold air channel 1c into the air duct chamber 1b through the through hole 12a, and then the hot air is blown from the upper part of the air duct chamber 1b to the heating chamber 1a by the hot air impeller 212, and finally the hot air is discharged from the air outlet 1d At the same time, the cold air impeller 211 discharges the remaining cold air in the cold air channel 1c from the air outlet 1d. At this time, the hot air and cold air discharged from the air outlet 1d mix with each other to reduce the outlet air temperature, which can effectively prevent burns at the air outlet 1d. In this embodiment, the hot air impellers 212 on the upper cooking layer 101 and the lower cooking layer 102 are on the same horizontal plane as the heating elements 3 of the corresponding cooking layers, so that the airflow blown by the hot air impeller 212 can directly blow on the heating elements 3 of the corresponding cooking layers to achieve the purpose of direct heating.

[0037] like Figure 3-4As shown, the fuselage main body 1 is provided with an air guide cover 13, and the air guide cover 13 cooperates with the second partition plate 12 to form an air duct chamber 1b. The air guide cover 13 is used to guide the airflow in the heating chamber 1a to the air outlet 1d. By utilizing the guiding effect of the air guide cover 13, the hot air in the heating chamber 1a can be guided to be blown to the air outlet 1d.

When the air fryer is normally used, the airflow at the end is discharged through the exhaust hole 16a. At the same time, the dust-proof side cover can effectively prevent external dust or insects from entering the interior of the air fryer through the air inlet 1e.

The hot air is used to heat the food in the heating chambers 1a of the upper cooking layer 101 and the lower cooking layer 102 at the same time, and the two heating chambers 1a are isolated from each other, which can effectively prevent the heating chambers 1a of the upper and lower cooking layers from mixing flavors when cooking food. The hot air in the heating chamber 1a heats the food and then flows out through the air duct chamber 1b to realize air circulation. In addition, the present invention arranges the heating element 3 and the wind wheel assembly 21 at the same water position, so that The airflow is blown directly onto the heating elements 3 corresponding to the upper cooking layer 101 and the lower cooking layer 102 through the guiding effect of the wind wheel assembly 21, which is beneficial to reducing the flow rate loss of the airflow in the process of entering the heating chamber 1a, so that the airflow can maintain a high flow rate and blow directly to the heating element 3 to achieve heating and temperature rise. At the same time, the wind wheel assembly 21 of the utility model can blow air laterally to the heating element 3 at the same horizontal position, so that the generated hot air can better circulate high-flow rate hot air in the heating chamber 1a, and at the same time, it can also effectively reduce the impact noise of the airflow on the heating chamber 1a, effectively improve the hot air generation rate in the heating chamber 1a and the heating efficiency of the air fryer on the surface of the food, which has the advantages of effectively improving the heating and cooking efficiency, reducing noise, using double pots to increase the cooking capacity, and preventing the upper and lower cooking layers from mixing flavors during cooking. Specific embodiment 2
