Definitions
- An object of the invention is to provide a stirring impeller with improved stirring efficiency and a stirring device including the same, in view of the above problems.
- the kind of object to be stirred is not particularly limited.
- the liquid L also includes liquid or the like with higher viscosity and lower flowability other than liquid with lower viscosity and higher flowability.
- the plurality of blade units 43 are arranged at predetermined intervals along a circumferential direction of the support part 42.
- Each blade unit 43 is arranged so as not to jump out outward in the radial direction from the outer peripheral edge of the support part 42.
- an outer peripheral edge of each blade unit 43 and the outer peripheral edge of the support part 42 coincide with each other in a plan view.
- the circular-arc curved shape of the second blade part 43b is, specifically, a shape that is indicated in Fig. 2(a) and that is curved with a constant curvature radius (for example, a curvature radius m5 illustrated in Fig. 4(b) ) between two end edges having a parallel relationship with a one-dot chain line showing a receding angle ⁇ .
- the second blade part 43b of the present embodiment is curved with the constant curvature radius m5
- the invention is not limited to this, and the second curved part may be formed, for example, in a shape that is curved with different curvature radii depending on portions.
- the second blade part has a shape of which the curvature radius is made different partially from the side of the second blade part 43b fixed to the support part 42 toward an end part of the second blade part 43b.
