Abstract: Disclosed is a range hood, including: a case provided with a smoke inlet; and a fan provided inside the case. An air inlet area is formed between an air inlet of the fan and a side wall of the case, the air inlet area is provided with a spacer, and the spacer is configured to divide the air inlet area into at least two air inlet sub-areas. The air inlet sub-areas are located at different positions of the air inlet area. The airflow entering the case from the smoke inlet flows to the air inlet of the fan, and the airflow flows to the sub-air inlet area in different directions. The space blocks airflows in different directions, to prevent turbulence at the intersection of airflows in different directions.

Abstract: A range hood includes a housing defining a first outer air vent and a second outer air vent; a volute casing disposed within the housing, including a volute casing body having a bottom plate, a top plate and a side encasing plate disposed between the bottom plate and the top plate, the volute casing body defining an outer air outlet communicated with the first outer air vent and the second outer air vent, an opening direction of the outer air outlet being orthogonal to that of the second outer air vent; a fan wheel disposed within the volute casing body; and an outer switching cover plate movable between a first position, in which the first outer air vent is opened and the second outer air vent is closed, and a second position, in which the first outer air vent is closed and the second outer air vent is opened.
