Drain esp. for whirlpool bath has controlling valve cone moved by mechanism independently from intake cover, and cover fixed to base of bath

摘要

The drain has a bath-mounted intake (2) with cover (3), connected via a low-pressure chamber (9) to an intake pipe (10). The chamber and a drain (12) below it, are connected via a channel controlled by a valve cone (11). The cone is moveable independently of the cover, and is moved in opposite directions by pressure and traction, by a movement mechanism. The valve cone has a disc-shaped part with ring seal, which engages on a wall of the channel between low-pressure chamber and drain. The intake has ribs (4) arranged in a ring, to catch hairs.
