The invention relates to a stirring impeller which comprises a central turntable. At least three stirring blades which radially outwardly extend are mounted on the outer periphery of the central turntable and are symmetrically arranged relative to the center of the central turntable. The invention further provides a flocculation module and a washing machine with the flocculation module. A flocculation barrel and a stirring structure are arranged in the flocculation module. Water in the flocculation barrel can be stirred by the stirring structure, and the stirring structure comprises the stirring impeller mounted in the flocculation barrel. The stirring impeller, the flocculation module and the washing machine have the advantages that the stirring blades are mounted on the outer periphery of the central turntable, the stirring impeller is formed by the blades and the central turntable by means of detachable assembling, accordingly, the structure of the stirring impeller can be diversified, and the stirring impeller, the flocculation module and the washing machine are applicable to different use environments; the blades and the central turntable are detachably assembled, accordingly,production processes for the stirring impeller are simple, transport procedures are safe, and loss of the stirring impeller can be prevented.
