Range hood
By setting strip-shaped top and side suction ports on the range hood's smoke collection hood, combined with a negative pressure hood and fan system, the problems of increased noise and reduced smoke extraction efficiency under high pressure in range hoods have been solved, achieving low-noise and high-efficiency smoke extraction.

Abstract
This application relates to the field of home appliance technology and discloses a range hood, including a smoke collection hood. The smoke collection hood has a top suction port and a side suction port. The top suction port is located on the upper inner wall of the smoke collection hood, and the side suction port is located on the inner side wall of the smoke collection hood. Both the top suction port and the side suction port are strip-shaped structures. The plane containing the top suction port is parallel to the horizontal plane, and the side suction port extends from the lower end of the smoke collection hood towards the top suction port. This application achieves the desired smoke extraction effect while reducing airflow, increasing the inlet air velocity of the top and side suction ports, and reducing wind noise.
