Abstract

A cooker hood 1 is provided, including: a housing (30); a fan (11) mounted in the housing (30), where the fan (11) includes an air intake vent (11a) and an air exhaust vent (11b); and further including: an air guide pipe (12) mounted in the housing (30), where the air guide pipe (12) includes an air intake vent (12a) and an air exhaust vent (12b), and the air exhaust vent (12b) of the air guide pipe is connected to the air intake vent (11a) of the fan; and a pipe wall of the air guide pipe (12) is provided with acoustic attenuation micro holes. Noise generated when the cooker hood 1 runs leaks out of the acoustic attenuation micro holes on the air guide pipe (12) when passing through the air guide pipe (12), and the noise is reflected in space between the pipe wall of the air guide pipe (12) and the housing (30) back and forth for a plurality of times and is reduced after being reflected for the plurality of times, thereby achieving an effect of reducing the noise of the cooker hood.
