Title:
DRAIN IMPELLER
Document Type and Number:
Japanese Patent JP2018119459
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a drain impeller capable of increasing efficiency of drawn water, and decreasing generation of bubbles.SOLUTION: A drain impeller 10 includes one annular recessed plate 11 and one core shaft 21 having one board body 13 and one annular wall 15. The annular wall 15 is formed due to that the peripheral edge of the board body 13 extends upward. The core shaft 21 passes through the board body 13, and one flow passage 23 is formed therebetween. The apex of the core shaft 21 is positioned in the upper direction of the board body 13, and is used to connect to a drive shaft of a motor. The core shaft 21 below the board body 13 is a polygonal column 27, the polygonal column 27 has a plurality of plain surfaces 28, the plurality of plain surfaces 28 are connected in pairs, and one slender surface is formed in a place where they are connected.
