• and
• the fume gathering panel comprises a fume collecting port, which is configured to discharge oil fumes into an air duct of a range hood, and both the first air inlet and the second air inlet communicate with the fume collecting port;
• wherein the air deflector comprises an upper plate and a lower plate, wherein the lower plate, from bottom to top, is inclined from rear to front, the curved convex portion is located between the upper plate and the lower plate;
• and
• wherein the upper plate is arranged vertically;
• or the upper plate, from bottom to top, is inclined from rear to front at an angle α, less than 15°, from a vertical plane;
• and/or
• an angle β between the lower plate and the vertical plane satisfies 30°≤β≤45°.
