AI Technical Summary
Technical Problem
The installation of drainage components in gutters is cumbersome due to the difficulty in aligning the bell-mouth shaped upper end of the inner cylinder with the through-hole, leading to potential misalignment and increased inlet losses.
Method used
A drain design featuring a cylindrical section with a flange extending outward from the upstream end, a connecting portion with a linear region, and a gradual decrease in inner diameter, ensuring a clear corner for easy fitting and reduced inlet losses.
Benefits of technology
Facilitates easy installation by aligning the drain with the gutter inlet and reduces inlet losses, improving drainage performance.

Abstract
This provides a drain that allows for reduced inlet losses while also simplifying the installation process at the gutter inlet. [Solution] The drain 1 comprises a cylindrical portion 21 positioned at the inlet 10b of the gutter 10, a flange 22 extending outward from the upstream end 21a of the cylindrical portion 21 and having a mounting surface 222 that rests on the periphery of the inlet 10b in the gutter 10, and a cylindrical connecting portion 23 located between the upstream end 21a and the flange 22, the inner diameter of which gradually decreases from the flange 22 toward the cylindrical portion 21. The outer circumferential surface 232 of the connecting portion 23 includes a linear region 232a that is linear in a cross-section passing through the central axis C21 of the cylindrical portion 21. If Rr is the radius of curvature of the connecting portion 24 between the mounting surface 222 and the linear region 232a in the above cross-section, and θ1 is the angle between the normal N of the mounting surface 222 and the linear region 232a in the above cross-section, then 0≦Rr≦3mm and 0≦θ1≦45° are satisfied.
