The bell mouth has: an inner peripheral part 11 having a bell-mouth shape; an outer peripheral part 12 formed continuously with the inner peripheral part; and a flat surface 15 formed continuously to the inner peripheral part from a lower end 14 of the outer peripheral part. In the range hood, when the bell mouth is mounted on the suction port, the oil panel and the flue, and the flat surface formed continuously on the inner peripheral part from the lower end of the outer peripheral part form a substantially identical surface.SELECTED DRAWING: Figure 6 |
