Cooking device

A cooking device, comprising:

• a housing having a cooking cavity;
• a gas circulation apparatus disposed in the housing and configured to drive gas in the cooking cavity to flow and circulate, the gas circulation apparatus comprising a gas driving part, wherein when driven by the gas driving part, gas has a first part flowing in a first direction and a second part flowing in a second direction, one of the first direction and the second direction being a circumferential direction of the gas driving part, and another of the first direction and the second direction being a radial direction of the gas driving part,
• wherein the gas driving part comprises:
• a driving cover body having a plurality of air holes on a side surface of the driving cover body facing towards the cooking cavity of the cooking device;
• and
• a fan blade part rotatably arranged in the driving cover body,
• wherein the driving cover body comprises:
• a driving cover body top wall;
• and
• a driving cover body side wall connected to the driving cover body top wall, the fan blade part being located below the driving cover body top wall and surrounded by the driving cover body side wall,
• wherein the driving cover body side wall is formed as a divergent side wall, a small diameter end of the driving cover body side wall is connected to the driving cover body top wall, and a large diameter end of the driving cover body side wall is away from the driving cover body top wall,
• wherein the cooking device further comprises a heating apparatus arranged in the cooking cavity and adjacent to the driving cover body, wherein the driving cover body side wall has a virtual extension surface extending towards the cooking cavity, wherein a range formed by deflecting a predetermined small angle β towards two sides of the virtual extension surface with a large diameter end of the driving cover body side wall as a fulcrum is a predetermined range, and wherein a peripheral edge of the heating apparatus does not exceed the predetermined range.
