Title: Foamed water discharging port
Inventor: IMAZONO MASAHIKO
IPC: E03C1/084
Filed: 1989-11-21
Abstract: PURPOSE:To secure flow rate without causing pressure drop and clogging of a foreign matter and to always obtain properly foamed water by turning the supplied water to generate contrifugal force and sending it into a foam chamber as a conical water screen flow and mixing air therewith by lowering of the inner pressure. CONSTITUTION:Water introduced into a turning chamber 4 is made to a swirly turning flow. Centrifugal force toward the outside is allowed to act thereon and also the flow in a discharge port part opened in the nearly central part is made swirly. Water allowed to flow from the discharge port 3a is blown off to the outside by centrifugal force and sent into a foam chamber 5 as a conical water screen-shape. Thereby the introduced water is already made to an easily splashed state. When the foam chamber 5 is opened to the atmosphere by an air suction cylinder 22, air is sucked by evacuation effect based on the water introduced from the discharge port 3a at high velocity. This air is mixed into water which is allowed to collide against a net cylinder 25 and broken and thereafter discharged as foamed water. At this time, the net cylinder 25 prevents that foamed water is allowed to flow back to the air suction cylinder 22 side. Foamed water is sent out to a water discharging end side while regulating the flow thereof.
