[0036] In order to further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present utility model as follows.
[0037] As Figures 1-5 shown, the following embodiments disclose an exhaust structure of an air fryer, including,
[0038] A body 100, with a cooking cavity 101 formed inside, and the cooking cavity 101 has an open side;
[0039] A pot body 200, removably arranged inside the cooking cavity 101;
[0040] A hot air system 700, arranged on one side of the cooking cavity 101, for exchanging air flow with the inside of the cooking cavity 101;
[0041] The cooking cavity 101 is formed by being isolated from the inside of the body 100 through a wind guide shell 400, and a heat dissipation cavity 104 is formed between the wind guide shell 400 and the inner wall of the body 100;
[0042] An air inlet part, an air outlet part and the heat dissipation cavity 104 are communicated on the body 100;
[0043] It further includes a driving component 300 for driving the hot air system 700, and a heat dissipation fan 500 is arranged on the driving component 300, and the heat dissipation fan 500 is used for driving the air flow in the heat dissipation cavity 104.
[0044] The above is the basic solution of this embodiment.
[0045] Specifically referring to Figures 1 to 3 shown, in this embodiment, the open side of the cooking cavity 101 is located on the side of the body 100, and the pot body 200 is slidably arranged inside the cooking cavity 101;
[0046] The hot air system 700 is located inside the body 100;
[0047] An air inlet area and an air outlet area are arranged on one side of the pot body 200 close to the hot air system 700;
[0048] The wind guide shell 400 is a semi-surrounding structure with three sides, including a wind guiding surface and two side surfaces, and the opening side faces the open side of the cooking cavity 101;
[0049] The hot air system 700 is located outside the wind guide shell 400;
[0050] The driving component 300 is located outside the hot air system 700, and a heat dissipation fan 500 is arranged, and the heat dissipation fan 500 is located between the driving component 300 and the hot air system 700;
[0051] When the hot air system 700 is started, air exchange is carried out in the cooking cavity 101 to form hot air flow and input it into the interior of the cooking cavity 101. The hot air fills the entire hot air system 700, and the heat dissipates to the outside of the system, causing the air in the heat dissipation cavity 104 to heat up;
[0052] When the driving component 300 rotates, it drives the heat dissipation fan 500 to rotate. The heat dissipation fan 500 drives the air in the heat dissipation cavity 104. The air inlet part of the machine body 100 inputs external air flow into the heat dissipation cavity 104, and takes out the hot air in the heat dissipation cavity 104 from the air outlet area to cool the heat dissipation cavity 104;
[0053] Preferably, in this embodiment, the driving component 300 is a driving motor.
[0054] In this embodiment, both the heat dissipation fan 500 and the driving component 300 are located in the heat dissipation cavity 104, and the driving component 300 and the hot air system 700 are separated by the heat dissipation fan 500. When the external air flow enters from the air inlet part, under the action of the heat dissipation fan 500, a heat dissipation air flow is formed. The heat dissipation air flow moves to the area of the heat dissipation fan 500 and mixes with the hot air. That is to say, when the heat of the hot air system 700 transfers heat to the air outside it, it only conducts to the position of the heat dissipation fan 500, that is, it is driven by the heat dissipation fan 500 and cannot reach the position of the driving component 300, avoiding the temperature rise of the driving component 300;
[0055] In addition, the heat generated by the driving component 300 due to its own work has been taken away during the process of the heat dissipation air flow moving to the position of the heat dissipation fan 500, realizing the cooling of the driving component 300.
[0056] In this embodiment, in order to further separate the hot air and the driving component 300, a heat insulation cover 600 is provided in the heat dissipation cavity 104. The opening side of the heat insulation cover 600 is connected to the outer wall of the air guide shell 400, separating the heat dissipation cavity 104 into a connected cold air area 104.1 and a hot air area 104.2. The hot air system 700 is located inside the heat insulation cover 600 and is connected to the hot air area 104.2 inside the heat insulation cover 600.
[0057] Preferably, the driving component 300 is located in the cold air area 104.1, and the heat dissipation fan 500 is located in the hot air area 104.2.
[0058] Specifically refer to Figure 3 and Figure 4 As shown, the heat insulation cover 600 is a cover body with an opening on one side, and the opening is connected to the end face of the air guide shell 400. The driving component 300 is located outside the heat insulation cover 600, and the heat dissipation fan 500 is located between the heat insulation cover 600 and the air guide shell 400; at the same time, the heat insulation cover 600 is provided with ventilation holes 601;
[0059] Based on the above settings, the hot air in the hot air area 104.2 of the heat shield 600 can only be output to the cold air area 104.1 through the ventilation holes 601, reducing the output volume of the hot air and further avoiding heat conduction to the driving component 300.
[0060] A air outlet duct a is provided on the side of the heat shield 600 extending towards the air outlet part, and the air outlet duct a connects the hot air area 104.2 and the air outlet part.
[0061] In this embodiment, the air outlet duct a is provided on the side of the heat shield 600, and the heat dissipation air flow can only be output to the air outlet part through the air outlet duct a and cannot overflow to other positions, ensuring the heat dissipation efficiency.
[0062] In this embodiment, the air inlet part is a plurality of air inlets 105 provided at the bottom of the machine body 100.
[0063] The air outlet part is the air outlet 102 provided on the machine body 100.
[0064] The air outlet duct a completely covers the air outlet 102.
[0065] In this embodiment, the specific setting method of the hot air system 700 is as follows: the hot air system 700 includes a hot air shell 710, an air flow driving component 720300 and a heating component 730 provided in the hot air shell 710, and a heat dissipation hole 711 is provided on the hot air shell 710 and communicated with the air outlet duct a.
[0066] Specifically, referring to Figure 5 As shown, in this embodiment, a partition 740 is provided in the hot air shell 710 to divide the hot air shell 710 into a heating space and a driving space. The air flow driving component 720 is located in the driving space, and the heat dissipation hole 711 is located on the side of the driving space;
[0067] The air in the cooking cavity 101, under the action of the air flow driving component 720, sequentially passes through the heating space and the driving space. When entering the driving space, it is already hot air flow. A part of the hot air flow is output from the air outlet part of the hot air system 700 to the cooking cavity 101, and a small amount of the hot air flow is dissipated to the outside of the machine body 100 through the heat dissipation hole 711 through the air duct.
[0068] In this embodiment, two cooking pots 200 are provided up and down in the machine body 100. Therefore, two heat dissipation fans 500, two driving components 300 and two hot air systems 700 are provided, and two air outlet areas on the machine body 100 are correspondingly provided.

Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content without departing from the technical solution scope of the present utility model.
