The contact part of the top cover 1 and the upper shell 2 is provided with a first air inlet 12, and the side surface of the upper shell 2 is provided with a mixed air outlet 14. The cold air flows into the heat dissipation fan 5 from the first air inlet 12, and is driven by the heat dissipation fan 5 to cool the motor 4, and finally flows out from the mixing air outlet 14. Since there is no restriction between the upper casing 2 and the upper core 3, the cool air can flow freely in the first interlayer (the arrows in fig. 1 represent the flow of the air flow), so that part of the air after absorbing heat flows back to the motor 4 and the heat dissipation fan 5, and the heat dissipation effect is reduced.

Referring to fig. 4-8, an air fryer with good heat dissipation is shown, the air fryer has a cooking cavity 10, an upper core 3, an upper housing 2, an air duct plate 6, a motor 4 and a heat dissipation fan 5 are arranged above the cooking cavity 10, a heat dissipation channel 7 for air circulation is formed among the upper core 3, the upper housing 2 and the air duct plate 6, and a blocking member is arranged between the upper housing 2 and the upper core 3, and is used for guiding external cold air to flow to the heat dissipation fan 5 and blocking air flow in the heat dissipation channel 7 from flowing back to the heat dissipation fan 5. Here, the external cold air refers to air from the outside, and the air flow in the heat dissipation channel 7 refers to air flow which circulates in the heat dissipation channel after the external cold air absorbs heat.

The air fryer can be a drawer type air fryer or a flip type air fryer, and the embodiment is described by taking the flip type air fryer as an example. The air fryer comprises a fryer body and a fryer cover, a cooking cavity 10 is formed between the fryer body and the fryer cover, and the fryer cover sequentially comprises an upper shell 2, a motor 4, an upper core 3, a cooling fan 5 and an air duct plate 6 from top to bottom.

The top of the upper shell 2 is provided with a groove, the middle position of the upper end of the groove is provided with a top cover 1, an air inlet 12 is arranged between the top cover 1 and the upper shell 2, the upper core 3 is provided with a plurality of air outlets 13, and the side surface of the upper shell 2 is provided with a mixed air outlet 14. After entering from the air inlet 12, the cold air enters the heat dissipation fan 5 from the inner interlayer under the guidance of the barrier piece; under the driving of the cooling fan 5, the cold air cools the motor 4, is thrown out from the air outlet 13 of the upper core 3, flows to the mixing air outlet 14 along the outer surface of the upper core 3, and finally flows out from the mixing air outlet 14 (the arrows in fig. 4 and 5 represent the flowing condition of the air flow). In addition, because the upper part of the air duct plate 6 is provided with the heat dissipation system, and the lower part of the air duct plate 6 is provided with the heating system, part of heat can be dissipated from the air duct plate 6 in the working process, so that a small amount of hot air exists in the second interlayer, and the hot air is mixed with cold air and then discharged from the mixed air outlet 13.

This corresponds to forming a wind pressure chamber (inner sandwich) between the upper casing 2 and the upper core 3, which increases the air pressure, and performing pressurization and guiding of the airflow direction at the same time by using the wind pressure chamber.

Further, the side wall of the first and/or

second collarette

8, 9 is corrugated. The strength of the first surrounding bone 8 and/or the second surrounding bone 9 can be greatly increased by the corrugated structure, and materials can be reduced by applying the corrugated structure, so that the cost is reduced; secondly after cold wind contacts first round bone 8 or second round bone 9, the ripple structure can rebound cold wind, has increased the kinetic energy of wind, and then has improved the radiating effect.

Further, one surface of the first surrounding bone 8 and/or the second surrounding bone 9 facing the motor 4 is an arc surface, and the arc surface is curved towards one side of the motor 4. So when making first enclose bone 8 and second and enclose bone 9 butt, the intermediate region of interior intermediate layer is narrower and small, gets into the back from first air intake 12 when cold air, during intermediate region through middle interior intermediate layer, and air pressure can increase for the cold air that gets into radiator fan 5 has great speed, and cold air can dispel the heat the cooling to motor 4 high-efficiently when high-speed operation.
