Abstract

Claims (45)

1 . A water trap for use in connection with a wash basin or other plumbing fixture, the water trap comprising:

a housing, wherein the housing comprises:

a top;

a bottom;

a plurality of side walls; and

a plurality of end walls;

an inlet extending into the housing;

an outlet extending out of the housing;

a weir inside the housing between the inlet and the outlet;

a trap chamber defined by the space within the housing on an upstream side of the weir, wherein the trap chamber is designed to retain liquid following a drain cycle from the wash basin or other plumbing fixture; and

an inlet baffle extending downward from the top of the housing into the trap chamber; and

an air pocket between the inlet baffle and the inlet, wherein the air pocket contains pressurized air during use.

2 . The water trap of claim 1 , wherein the inlet includes a discharge end that is configured to be submerged within the liquid retained within the trap chamber.

3 . The water trap of claim 1 , further comprising:

a cleanout port that provides access to the trap chamber; and

a removable plug connected to the cleanout port.

4 . The water trap of claim 1 , wherein the inlet includes a discharge end that is spaced above the bottom of the housing at a first height (h 1 ); and wherein the weir extends upward from the bottom of the housing to a second height (h 2 ).

5 . The water trap of claim 4 , wherein the second height (h 2 ) is greater than the first height (h 1 ), such that the discharge end of the inlet is located closer to the bottom of the housing than an upper portion of the weir.

6 . The water trap of claim 5 , wherein the outlet is a dual-sided outlet that includes a pair of discharge ports aligned along a lateral axis that is substantially orthogonal to a longitudinal axis extending between the plurality of end walls.

7 . The water trap of claim 1 , wherein the housing includes a funnel section proximate to the outlet and downstream from the weir.

8 . The water trap of claim 1 , wherein the inlet is substantially vertical and the outlet is substantially horizontal.

9 . A water trap for use in connection with a floor drain, the water trap comprising:

a housing;

an exterior grate on the top of the housing;

a deflector plate under the exterior grate;

an inlet baffle connected to a distal end of the deflector plate;

an intake channel between the inlet baffle and the housing;

an outlet extending from the housing;

a weir inside the housing between the inlet baffle and the outlet; and

a trap chamber defined by the space within the housing on an upstream side of the weir, wherein the trap chamber is designed to retain liquid following a drain cycle from the floor drain; and

wherein the deflector plate is removable to provide access to the trap chamber located under the deflector plate.

10 . The water trap of claim 9 , wherein a lower end of the inlet baffle is configured to be submerged within the liquid retained within the trap chamber.

11 . The water trap of claim 9 , wherein the housing includes a bottom, a plurality of ends and a plurality of sides.

12 . The water trap of claim 11 , wherein the lower end of the inlet baffle is spaced above the bottom of the housing by a first height (h 1 ).

13 . The water trap of claim 12 , wherein the weir extends above the bottom of the housing by a second height (h 2 ) that is greater than the first height (h 1 ).

14 . A water trap for use in connection with a floor drain, the water trap comprising:

a housing;

an exterior grate on the top of the housing;

a deflector plate under the exterior grate;

an inlet baffle connected to a distal end of the deflector plate;

an intake channel between the inlet baffle and the housing;

an outlet extending from the housing;

a weir inside the housing between the inlet baffle and the outlet;

a trap chamber defined by the space within the housing on an upstream side of the weir, wherein the trap chamber is designed to retain liquid following a drain cycle from the floor drain; and

wherein the deflector plate is hinged to permit the deflector plate to be opened to provide access to the trap chamber located under the deflector plate.
