5. The food processor of claim 1, wherein the IGBT comprises a heat sink provided on the IGBT body and a heat sink provided on the IGBT body, and the heat sink fan is provided on a side close to the heat sink.

6. The food processor of claim 5, wherein a plurality of heat radiating fins are arranged side by side, and a heat radiating gap is formed between the heat radiating fins, and the extending direction of the heat radiating gap is the same as the direction of the air flow discharged from the heat radiating fan.

7. The food processor of claim 5, wherein the housing comprises a housing for housing the brushless motor and the IGBT, the heat dissipation channel comprises a main air inlet provided in a bottom wall of the housing, a clearance space is formed between a side of the IGBT main body adjacent to the main air inlet and the housing, and the heat dissipation fan is provided in the clearance space.

8. The food processor of claim 7, wherein the cooling fan has a fan inlet and a fan outlet, the fan outlet facing the side of the heat sink and at least partially overlapping the heat sink.

9. The food processor of claim 1, wherein the housing includes a housing for housing the brushless motor and the IGBT, the housing having two baffles extending inward, and wherein the extending ends of the two baffles abut the IGBT to form the heat dissipation channel around the IGBT.

10. The food processor of claim 9, wherein a gasket is further provided between the baffle and the IGBT.
