Abstract
A sink trap having a generally semi-global main chamber, a shallow water chamber, a plurality of baffles for supporting the water chamber in the main chamber in an inwardly spaced relation and define a plurality of volute passageways between the main and water chambers and a cap detachably secured to the upper edge of the main chamber and an inlet pipe extending axially downwardly through the cap into the water chamber to lead drainage into the water chamber and discharging the drainage by overflowing the water chamber to flow through the volute passageways forming a turbulent liquid flow along a drainage pipe line to prevent the drainage pipe line from becoming choked with impassable matter.
Claims2
A sink-trap comprising:
- a semi-global outer chamber defining an inner space and having a laterally-extending rim on an upper end and an outlet pipe attached to a lower end, said outlet pipe defining a first passageway communicating the inner space;
- a water chamber adapted to be located in the inner space of the outer chamber;
- a plurality of baffle members spirally disposed on an outer circumference of the water chamber to support the water chamber within the outer chamber in an inwardly spaced relation and define a plurality of volute passageways between the outer and water chambers to communicate the the first passageway in the outlet pipe;
- a cap member secured to the upper end of the outer chamber and having an annular groove for receiving the rim of the outer chamber;
- and
- an inlet pipe extending downwardly through the cap member into the water chamber.
