Wherein the appliance body 10 has a cooking cavity 1. The first cover 20 is disposed on the device body 10. The heat dissipation fan 30, the driving device 40 and the hot air generating device 50 are sequentially arranged in the first cover body 20 from top to bottom, the driving device 40 is in driving connection with the hot air generating device 50, the hot air generating device 50 supplies air into the cooking cavity 1, the air suction side of the heat dissipation fan 30 faces the driving device 40, a first air outlet 211 which communicates the inside of the first cover body 20 with the outside of the appliance body 10 is arranged on the first cover body 20, and the air outlet side of the heat dissipation fan 30 is opposite to the first air outlet 211.

By applying the technical solution of the embodiment, the heat dissipation fan 30 is disposed on the side of the driving device 40 away from the hot air generating device 50, so that the heat dissipation fan 30 is far away from the hot air generating device 50, the temperature rise of the heat dissipation fan 30 is low, the temperature transmitted to the driving device 40 is reduced, the heat dissipation effect of the driving device 40 is enhanced, and the service life of the driving device 40 is prolonged.

Specifically, in the present embodiment, the heat dissipation fan 30 is located at the upper side of the driving device 40, and the heat dissipation fan 30 sucks up the hot air around the driving device 40 to lower the ambient temperature around the driving device 40, so that the temperature rise of the driving device 40 is reduced.

As shown in fig. 2 to 4, in the present embodiment, the distance H between the heat dissipation fan 30 and the hot air generating device 50 is between 40mm and 110 mm. If the distance H is less than 40mm, the heat dissipation fan 30 and the driving device 40 are close to the hot air generating device 50, which results in a high temperature rise of the driving device 40, and if the distance H is greater than 110mm, the heat dissipation fan 30, the hot air generating device 50 and the driving device 40 occupy a large space in the vertical direction of the first cover body 20, which further results in an excessively thick thickness of the first cover body 20, which is not favorable for miniaturization design.
