A guiding mechanism, includes a guiding surface enclosed by a first curve segment, a second curve segment, a third curve segment and a first straight line segment; a starting point of the first curve segment is defined as an origin of coordinates, two perpendicular straight lines passing through the origin of coordinates on a plane where the first curve segment is located are respectively defined as X-axis and Y-axis, and a line perpendicular to both the X-axis and the Y-axis is defined as Z-axis; coordinates of an ending point of the first curve segment is (x3,y3), x3≠0 and y3≠0. The present invention also discloses a centrifugal fan and a range hood.

Guiding mechanism, centrifugal fan thereof, and range hood thereof

A parallel double fan system, includes two fan systems disposed in parallel; wherein each fan system includes a volute having a front cover, a rear cover and an annular wall; the annular wall has a volute tongue; the rear cover has a first air outlet located above the corresponding volute tongue, two first air outlets in the two fan systems are communicated with each other. A range hood equipped with the parallel double fan system is also disclosed.

Parallel double fan system and a range hood thereof

An air guide box includes a box body. The box body includes a first wall and a second wall disposed opposite to each other. The first wall has an air inlet. Air outlets are respectively disposed between corresponding edges of the first and second walls. The second wall is recessed toward the first wall, and a portion of the second wall corresponding to the air inlet is a largest recessed position. From the largest recessed position to the air outlets, the second wall is gradually inclined in a direction away from the first wall, so that an inner surface of the second wall facing the first wall forms guiding slopes respectively form the largest recessed position to the edges of the first and second walls.

Air guide box and internal-circulation range hood having the same

A range hood, includes a fan system (), the fan system () having a volute () and an impeller (); the volute () includes a front cover (), a rear cover () and an annular wall (); the annular wall () has a volute tongue (); the front cover () has an air inlet (), the air inlet () faces downward to make the range hood to be a horizontal range hood; the volute tongue () is gradually inclined from the rear cover () to the front cover () in a direction opposite to the rotation direction of the impeller ().

Range hood

A fan system is provided, which includes a volute having a front cover, a rear cover and an annular wall connected between the front cover and the rear cover; an impeller disposed inside the volute, and a motor; the front cover has an air inlet facing downward in the state when the fan system is mounted; the motor includes a motor body and an edge; the edge is connected to the rear cover at the side of the rear cover facing the air inlet. A range hood equipped with the fan system and a mounting method for a flow guide device of the range hood are provided.
