Description

Technical Field

[0001] The invention relates to the field of air fryers, and in particular to a fryer with a double-layer air duct. Background Art

[0002] In the existing upper and lower air fryers, the top of the cooking cavity in the pot body is provided with a heating device, a driving motor and a fan blade. The working principle is that the fan blade is driven by the motor to generate airflow, and the airflow heats the food in the pot body with the heat generated by the heating device. However, in this setting, the motor on the top is also affected by the heating device, and the motor cannot work for a long time in a high temperature environment, which will increase the failure rate of the motor and reduce the working life of the motor.

[0003] Secondly, there is a heating device on the top of the machine, and a driving motor and fan blades are set on the back of the machine. Its working principle is to drive the fan blades of the motor on the back to generate airflow, which blows into the heating device on the top from the back, bringing the heat of the heating body into the pot body. The above solution has the problem that the temperature in the strong wind area is high, and the temperature in the windless or weak wind area is low, which is prone to uneven heating of food. Summary of the invention

[0004] In order to solve the above problems, the present technical solution provides a fryer with a double-layer air duct.

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

[0006] A double-layer air duct fryer, comprising a pot body, an upper fryer assembly is arranged in the pot body, an upper heating device for heating the upper fryer assembly is arranged at an upper compartment of the pot body, an upper DC fan is arranged at an upper compartment of the pot body, and an upper limit air duct is arranged at the periphery of the upper heating device, one end of the upper limit air duct receives the wind force of the upper DC fan, and the other end is communicated with the upper air outlet of the pot body;

[0007] A lower fryer assembly is also provided in the pot body, a lower heating device for heating the lower fryer assembly is provided at the lower compartment of the pot body, a lower DC fan is provided at the lower compartment of the pot body, and a lower limit air duct is provided at the outer periphery of the lower heating device, one end of the lower limit air duct receives the wind 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 to be arc-shaped, and the aperture at the air inlet is smaller than the aperture at the air outlet.

[0009] In some embodiments, the upper heating device includes a wind wheel arranged at the center of the pot body, and a heating tube arranged around the outer periphery of the wind wheel.

[0010] The beneficial effects of this application are:

[0011] In the present application, a DC fan is used to blow cold air from outside the whole machine into the inside. After the cold air enters the cavity, convection exchange is performed with the cavity to continuously reduce the temperature inside the cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] Please refer to Figure 1-5 As shown, a double-layer air duct fryer comprises a pot body 1, an upper fryer assembly 2 is arranged in the pot body 1, an upper heating device 3 for heating the upper fryer assembly 2 is arranged at the upper compartment of the pot body 1, an upper DC fan 4 is arranged at the upper compartment of the pot body 1, and an upper limit air duct 5 is arranged at the outer periphery of the upper heating device 3, one end of the upper limit air duct 5 receives the wind force of the upper DC fan 4, and the other end is communicated with the upper air outlet 6 of the pot body 1;

[0020] A lower frying pot assembly 7 is also provided in the pot body 1. A lower heating device 8 for heating the lower frying pot assembly 7 is provided at the lower compartment of the pot body 1. A lower DC fan 9 is provided at the lower compartment of the pot body 1. A lower limit air duct 10 is also provided at the outer periphery of the lower heating device 8. One end of the lower limit air duct 10 receives the wind 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] The present application sets a reasonable limited air duct so that the DC fan blows in cold air from the outside. After passing through the specific direction of the air duct, the air flow first flows through the motor windings and the fuse, thereby reducing the ambient temperature around the motor, effectively controlling the temperature rise of the motor and greatly improving its service life. In addition, the air duct route is introduced into the component area, which greatly reduces the temperature rise of the components and achieves the goal of cooling the entire internal temperature of the cavity.

[0022] In this embodiment, the upper limit air duct 5 is designed to be arc-shaped, and the aperture at the air inlet is smaller than the aperture at the air outlet, so that the airflow passing through the arc can be guided, thereby ensuring that it can completely pass through the circuit board and the motor, and then diffusely blow air, which is conducive to reducing the temperature.

[0023] In this embodiment, the upper heating device 3 includes a wind wheel 12 arranged at the center of the pot body 1, and a heating tube 13 arranged around the outer periphery of the wind wheel 12. In order to solve the problem of poor baking uniformity of food in the upper and lower pots, a heating device (the heating device is designed to be in a circular shape) is provided on the top of the cavity, and fan blades are installed in the middle of the heating device. The top motor drives the fan blades, and the fan blades drive the airflow to evenly diffuse the heat of the heating device to the food, so that the food can be evenly heated during baking, 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 the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
