The invention discloses a wind engine volute of Europe-type kitchen ventilator, which can adsorb wind via two surfaces. Wherein, the front and back cover plates (1, 2) are both mounted with wind inlets (11, 21); the edge of front cover plate (1) is formed by a straight line (AB), several arcs (BC, CD, DE, EF, FG, GH) and straight lines (HJ, JA); the edge of back cover plate (2) is formed by a straight line (A'B'), several arcs (B'C, C'D', D'E', E'F', F'G, G'H'), and a straight line (H'A'); the ratio between the radius of edge (FG) at the volute tongue of front cover plate (1) and the edge radius of edge (G'H') at the volute tongue of back cover plate (2) is 7.3-18.5. Compared to present technique, the invention can generate a new noise source at the volute tongue, which is reverse to other noise, to be eliminated some.
