Description

Technical Field

[0001] The utility model relates to cooking technology, in particular to a cooking device. Background Art

[0002] A conventional cooking device using electromagnetic heating includes a base, a mounting cavity is formed in the base, an air outlet is provided on one side of the mounting cavity and communicates with the outside of the cooking device, the electromagnetic heating coil and the control circuit board are both arranged in the mounting cavity, the fan and the air outlet are respectively arranged on opposite sides of the electromagnetic heating device, when the cooking device is working, the wind flow generated by the fan enters the mounting cavity, and finally flows out of the cooking device from the air outlet to dissipate heat for the electromagnetic heating coil.
