A second wind deflector 7 is also provided in the electrical appliance compartment 104, the second wind deflector 7 is located at the rear side of the cooking main body 100 and is bent upwards toward the front to form an arc structure, the second wind deflector 7 The specific structure is shown in Figure 9.

The flow direction of the airflow blown by the cooling fan 1 to the electrical appliance compartment 104 is shown in Figures 3 and 4, the wind is sucked into the cooling fan 1 from the air inlet 101 in front of the cooking body 100, and then the first air outlet 111 of the cooling fan 1 Air is supplied to the electrical appliance compartment 104, and the downward flowing wind blows to the transformer 4 under the guidance of the first wind deflector 6, and then when it blows to the second wind deflector 7 on the rear side, the second wind deflector 7 passes through the arc. The shaped structure enables the wind to turn flexibly, continue to blow to the magnetron 5, and then control whether the wind blows into the heating chamber through the windshield assembly (not shown in the figure).

Wherein, the windshield assembly is an assembly set on the cooking main body 100 to control whether the wind in the electrical appliance compartment 104 enters the heating chamber (the windshield assembly is not the focus of this application and will not be described in detail), usually in In the microwave mode, the windshield component is opened, so that the wind enters the heating chamber, which is beneficial to reduce the problem of water accumulation in the chamber; in the hot air mode, the windshield component is closed, so that the temperature in the heating chamber can be rapidly increased. The wind in the storehouse 104 is discharged from the air outlet on the bottom support plate 8 . The bottom support plate 8 is arranged at the bottom of the electrical appliance compartment 104, and is used to support components such as microwave components. Its structure is shown in FIG. Exhausted from the exhaust port 81.
