Document Type and Number:
Japanese Patent JP6964554
Kind Code:
B2
Abstract:
A water discharging impeller includes: an annular concave disk and a core shaft. The annular concave disk has a disk body and an annular wall. The core shaft is divided into an upper shaft part and a lower shaft part. The upper shaft part is arranged above the disk body, and the upper shaft part is radially and outwardly extended with a plurality of support ribs. The core shaft passes through the disk body, is spaced from the disk body with a preset distance, and is connected to the annular concave disk via the plurality of support ribs. The lower shaft part is formed as a columnar member and arranged below the disk body, the lower shaft part has at least one convex rib, the at least one convex rib is outwardly protruded from a surface of the lower shaft part, and spirally surrounds the lower shaft part from top to bottom, wherein a spiral direction, defined from top to bottom, of the at least one convex rib is the same as a driving direction of the core shaft being driven to rotate by a driving shaft.
