Abstract
A household appliance (1) for washing articles having at least one electric pump (8) for circulating or draining water; the electric pump (8) having an outer volute (9) having an inner pumping chamber (9a), an impeller (10) housed in axially rotating manner inside the pumping chamber (9a), and an electric motor (11) connected mechanically to the impeller (10) to rotate it about a rotation axis (A); the impeller (10) in turn having a central hub (17) coaxial with the rotation axis (A), and at least one movable projecting blade (18) fitted to the central hub (17) and movable between a fully retracted position in which the blade (18) is almost totally withdrawn inside the central hub (17), and a fully extracted position in which the blade (18) projects from the central hub (17) so that the outer lateral edge (18a) of the blade is further from the rotation axis (A) than when the blade (18) is in the fully retracted position.
