[0051] The cooking cavity 101 is formed by being isolated from the inside of the body 100 through an air guide housing 400, and a heat dissipation cavity 102 is formed between the air guide housing 400 and the inner wall of the body 100;

[0052] The body 100 is provided with an air inlet part and an air outlet part communicating with the heat dissipation cavity 102;

[0053] It further includes a driving component 500 for driving the hot air system 300, and a heat dissipation fan 600 is disposed on the driving component 500, and the heat dissipation fan 600 is used for driving the air flow in the heat dissipation cavity 102;

[0054] A heat insulation cover 700 is provided in the heat dissipation cavity 102. The heat insulation cover 700 divides the heat dissipation cavity 102 into an air inlet area 102.1 and an air suction area 102.2; the air inlet part is communicated with the air inlet area 102.1;

[0055] Both end parts on two sides of the heat insulation cover 700 are connected with the inner wall of the machine body 100.

[0056] The above is the basic solution of this embodiment.

[0057] Specifically, referring to Figures 1 to 3 As shown, in this embodiment, the open side of the cooking cavity 101 is located on the side of the machine body 100, and the pot body 200 is arranged in the cooking cavity 101 in a pull-out manner;

[0058] The hot air system 300 is located inside the machine body 100;

[0059] An air inlet area 102.1 and an air outlet area are arranged on one side of the pot body 200 close to the hot air system 300;

[0060] The air guide shell 400 is a semi-surrounding structure with three sides, including a wind guiding surface and two side surfaces, and the open side faces the open side of the cooking cavity 101;

[0061] The hot air system 300 is located outside the air guide shell 400;

[0062] The driving component 500 is located outside the hot air system 300, and a heat dissipation fan 600 is provided, and the heat dissipation fan 600 is located between the driving component 500 and the hot air system 300;

[0063] When the hot air system 300 is started, air flow exchange is carried out in the cooking cavity 101, a hot air flow is formed and input into the interior of the cooking cavity 101, the hot air flow fills the entire hot air system 300, and the heat dissipates to the outside of the system, so that the air in the heat dissipation cavity 102 is heated;

[0064] When the driving component 500 rotates, it drives the heat dissipation fan 600 to rotate. The heat dissipation fan 600 drives the air in the heat dissipation cavity 102. The air inlet part of the machine body 100 inputs external air flow into the heat dissipation cavity 102, and takes out the hot air in the heat dissipation cavity 102 from the air outlet part to cool the heat dissipation cavity 102;

[0065] Preferably, in this embodiment, the driving component 500 is a driving motor.

[0066] In this embodiment, a heat insulation cover 700 is arranged in the heat dissipation cavity 102. When the heat dissipation fan 600 operates, external air enters the air inlet area 102.1 through the air inlet part to form a heat dissipation air flow. The heat dissipation air flow is sucked into the air suction area 102.2 through the air passing holes on the heat insulation cover 700, mixes with the hot air in the air suction area 102.2, and is output from the air outlet part of the body 100 for heat dissipation.

[0067] Specifically refer to Figure 3 As shown, the two side ends of the heat insulation cover 700 are connected to the inner wall of the body 100, dividing the heat dissipation cavity 102 into two chambers; at the same time, there is an air passing gap between the bottom of the heat insulation cover 700 and the bottom of the body 100.

[0068] In this embodiment, the open side of the heat insulation cover 700 is connected to the outer wall of the air guide shell 400, dividing the air suction area 102.2 into a cold air chamber 102.21 and a hot air chamber 102.21.

[0069] Preferably, in this embodiment, the driving component 500 is located in the cold air chamber 102.21, and the heat dissipation fan 600 is located in the hot air chamber 102.21.

[0070] A cold air chamber 102.21 is arranged between the hot air system 300 and the driving component 500, and the heat in the hot air chamber 102.21 cannot be conducted to the driving component 500, thus ensuring the stability of the working environment temperature of the driving component 500.

[0071] Specifically refer to Figure 3 and Figure 4 As shown, the heat insulation cover 700 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, isolating a hot air chamber 102.21 at the back of the air guide shell 400; the driving component 500 is located outside the heat insulation cover 700, and the heat dissipation fan 600 is located in the hot air chamber 102.21 formed by the heat insulation cover 700 and the air guide cavity; at the same time, the heat insulation cover 700 is provided with ventilation holes 701;

[0072] Based on the above settings, the hot air in the hot air chamber 102.21 inside the heat insulation cover 700 can only be output to the cold air chamber 102.21 through the ventilation holes 701, reducing the output amount of the hot air flow and further avoiding the heating of the driving component 500.

[0073] An air outlet duct a is extended from the side part of the heat insulation cover 700 towards the air outlet part, and the air outlet duct a connects the hot air chamber 102.21 and the air outlet part.

[0074] In this embodiment, an air outlet duct a is provided on the side of the heat shield 700. The cooling 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 cooling efficiency.

[0075] In this embodiment, the air outlet part includes a first air outlet 103 provided on the side of the body 100 and a second air outlet 104 provided on the top of the body 100;

[0076] The air outlet duct a is connected to the first air outlet 103;

[0077] The air suction area 102.2 is connected to the second air outlet 104.

[0078] In this embodiment, two air outlet parts are provided, and the cooling air flow can be discharged and cooled through the first air outlet 103 and the second air outlet 104, improving the cooling efficiency.

[0079] In addition, in this embodiment, part of the cooling air flow in the air suction area 102.2 conducts the heat generated by the driving component 500 itself during operation and is output from the second air outlet 104, quickly dissipating the heat of the driving component 500 in a timely manner.

[0080] In this embodiment, the specific setting method of the second air outlet 104 is as follows: There is a hollow part b provided above the air suction area 102.2 on the top of the body 100. A top cover 800 is installed on the hollow part b, and the second air outlet 104 is located between the top cover 800 and the body 100.

[0081] The top surface 110 of the body 100 is set to a concave structure; the top cover 800 and the top surface 110 are connected by a top holding component and there is a gap.

[0082] Specifically refer to Figure 4 and Figure 6 As shown, the top surface 110 of the body 100 is set to a concave structure, and a top holding component is provided between the top cover 800 and the top surface 110, and the top holding component jacks up the top cover 800 so that there is a gap between the top cover 800 and the top surface 110 to form the second air outlet 104;

[0083] During cooling, the cooling air flow is output from the hollow part b and overflows along the second air outlet 104 formed between the top cover 800 and the top surface 110;

[0084] The function of this structure is to prevent the cooling air flow from directly rushing upward, and a gap is set so that it overflows from the side of the top cover 800, avoiding the safety hazard of the direct impact air flow to the user.

[0085] Preferably, in this embodiment, the air inlet part is a plurality of air inlets 105 provided at the bottom of the body 100.

[0086] The air outlet duct a completely covers the first air outlet 103.

A heat dissipation hole 311 is provided on the hot air housing 310 and is communicated with the air outlet duct a.

[0088] Specifically, referring to Figure 5 As shown, in this embodiment, a partition 340 is provided in the hot air housing 310 to divide the hot air housing 310 into a heating space and a driving space. The air flow driving component 500 is located in the driving space, and the heat dissipation hole 311 is located on the side of the driving space;

[0089] The air in the cooking cavity 101, under the action of the air flow driving component 500, sequentially passes through the heating space and the driving space. When it enters the driving space, it is already hot air. A part of the hot air is output from the air outlet part of the hot air system 300 into the cooking cavity 101, and a small amount of hot air is output to the outside of the machine body 100 through the heat dissipation hole 311 through the air duct for heat dissipation.

[0090] Preferably, in this embodiment, the air flow driving component 500 is a centrifugal fan, and the heat dissipation hole 311 is located on the side of the hot air housing 310.
