Description

Technical Field

[0001] This utility model relates to the field of air fryers, and more particularly to an air fryer with a double-layer air duct. Background Technology

[0002] Existing air fryers with upper and lower compartments each have a heating element, a drive motor, and a fan at the top of the cooking chamber. Their working principle involves the motor driving the fan to generate airflow, which then uses the heat from the heating element to heat the food inside the fryer. However, with this design, the top-mounted motor is also affected by the heating element, preventing it from operating at high temperatures for extended periods. This increases the motor's failure rate and reduces its lifespan.

[0003] Secondly, the top of the machine has a heating element, while the back has a drive motor and fan blades. The working principle is that the motor and fan blades at the back generate airflow, which blows into the top heating element, carrying the heat into the pot. This design results in high temperatures in areas with strong airflow, but low temperatures in areas with no or weak airflow, easily leading to uneven heating of the food during baking. Utility Model Content

[0004] To solve the above problems, this technical solution provides a deep fryer with a double-layer air duct.

[0005] To achieve the above objectives, the technical solution is as follows:

[0006] A double-layer air duct fryer includes a pot body, an upper fryer assembly inside the pot body, an upper heating device for heating the upper fryer assembly located at the upper partition of the pot body, an upper DC fan located at the upper partition of the pot body, and an upper limit air duct located at the outer periphery of the upper heating device. One end of the upper limit air duct receives the air force of the upper DC fan, and the other end is connected to the upper air outlet of the pot body.

[0007] The pot body is also provided with a lower fryer assembly. The pot body is provided with a lower heating device for heating the lower fryer assembly at the lower partition. The pot body is provided with a lower DC fan at the lower partition. It is also provided with a lower limiting air duct located on the outer periphery of the lower heating device. One end of the lower limiting air duct receives the air force of the lower DC fan, and the other end is connected to the lower air outlet of the pot body.

[0008] In some embodiments, the upper limit air duct is designed in an arc shape, and the diameter of the air inlet is smaller than the diameter of the air outlet.

[0009] In some embodiments, the upper heating device includes a fan wheel disposed at the center of the pot body and a heating tube surrounding the fan wheel.

[0010] The beneficial effects of this application are:

[0011] This application uses a DC fan to blow cool air from outside the unit into the interior. After the cool air enters the cavity, it exchanges air with the cavity through convection, continuously reducing the temperature inside the cavity. Attached Figure Description

[0018] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Please refer to Figure 1-5 As shown, a double-layer air duct fryer includes a pot body 1, an upper fryer assembly 2 inside the pot body 1, an upper heating device 3 for heating the upper fryer assembly 2 at the upper partition of the pot body 1, an upper DC fan 4 at the upper partition of the pot body 1, and an upper limit air duct 5 located on the outer periphery of the upper heating device 3. One end of the upper limit air duct 5 receives the air force of the upper DC fan 4, and the other end is connected to the upper air outlet 6 of the pot body 1.

[0020] The pot body 1 is also provided with a lower fryer assembly 7. The pot body 1 is provided with a lower heating device 8 for heating the lower fryer assembly 7 at the lower partition. The pot body 1 is provided with a lower DC fan 9 at the lower partition. It is also provided with a lower limiting air duct 10 located on the outer periphery of the lower heating device 8. One end of the lower limiting air duct 10 receives the air force of the lower DC fan 9, and the other end is connected to the lower air outlet 11 of the pot body 1.

[0021] This application sets up a reasonable limiting air duct, causing the DC fan to blow in cool air from the outside. After passing through the specific direction of the air duct, the airflow first flows over the motor windings and fuse, which reduces the ambient temperature around the motor and effectively controls the temperature rise of the motor, greatly improving its service life. In addition, the air duct is introduced into the component area, which greatly reduces the temperature rise of the components, achieving overall cooling of the cavity.

[0022] In this embodiment, the upper limit air duct 5 is designed in an arc shape, and the diameter of the air inlet is smaller than that of the air outlet, so that the airflow has a guiding effect when passing through the arc, thereby ensuring that it can completely pass through the circuit board and the motor, and then diffuse the airflow, which is beneficial to the temperature reduction.

[0023] In this embodiment, the upper heating device 3 includes a fan wheel 12 disposed at the center of the pot body 1 and a heating tube 13 surrounding the fan wheel 12. To solve the problem of uneven baking of food in the upper and lower pots, a heating device (designed as a ring shape) is provided at the top of the cavity, and a fan blade is installed in the middle of the heating device. The top motor drives the fan blade, and the fan blade drives the airflow to evenly diffuse the heat of the heating device to the food. During baking, the food can be heated evenly, thereby solving the problem of uneven heating of food in traditional back-blowing air frying.

[0024] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
