Protective cover for fan and cooking device

The utility model provides a protective cover for a fan and a cooking device. A plurality of air inlets are formed in the middle area of the protective cover for the draught fan, a plurality of air outlets are formed in the edge area of the protective cover for the draught fan, and the air outlets comprise a plurality of first air outlets located above the air inlets and a plurality of second air outlets located below the air inlets. The total ventilation area of the first air outlets is smaller than the total ventilation area of the second air outlets. Therefore, hot air flowing dead zones can be reduced. Due to the fact that the second air outlets are closer to the first heater and the first air outlets are farther from the first heater, the temperature of the space where the second air outlets are located is high, the liquidity of hot air can be improved by increasing the total ventilation area of the second air outlets, and the hot air convection effect can be improved; the temperature equalizing performa
