Abstract

A plumbing fixture includes a sump and a trapway extending from sump at an inlet of the trapway. A jet orifice is disposed in the trapway at approximately the inlet and defines an angled axis that is oriented upwardly toward an upper wall of the trapway and rearwardly toward an interior of the trapway. The jet orifice is configured to direct fluid from a fluid supply source to the trapway.

First claim

What is claimed is:

1. A urinal, comprising:
a sump;
a bowl fluidly connected to the sump;
a primary channel extending in a longitudinal direction of the urinal;
a first side channel split from the primary channel and extending along a first side of the bowl;
a second side channel split from the primary channel and extending along a second side of the bowl; and
a drain channel extending upward from the sump, wherein the first side channel and the second channel are fluidly connected to the drain channel.

2. The urinal of claim 1 , further comprising:
a trapway extending from the sump at an inlet of the trapway; and
a jet orifice disposed in the trapway at approximately the inlet.

3. The urinal of claim 2 , wherein the jet orifice defines an angled axis that is oriented upwardly.

4. The urinal of claim 2 , wherein the jet orifice is configured to direct fluid from a fluid supply source to the trapway to induce a flush cycle of the urinal.

5. The urinal of claim 1 , further comprising:
a cap coupled to the drain channel to close off the drain channel.

6. The urinal of claim 1 , wherein the first side channel and the second side channels are symmetrical.

7. The urinal of claim 1 , wherein the urinal is formed from a vitreous material.

8. The urinal of claim 1 , wherein the first side channel and the second side channels are substantially symmetrical about a plane extending through the urinal.

9. A urinal, comprising:
a sump;
a trapway extending from the sump at an inlet of the trapway;
a jet orifice disposed in the trapway at approximately the inlet;
a first side channel in fluid communication with the jet orifice; and
a second side channel in fluid communication with the jet orifice, wherein the second side channel is located opposite the first side channel.

10. The urinal of claim 9 , further comprising a drain channel extending from the jet orifice to a front portion of the urinal, wherein the drain channel is fluidly coupled to the first side channel, the second side channel, and the jet orifice.

11. The urinal of claim 10 , further comprising a cap coupled to the front portion to close off the drain channel.

12. The urinal of claim 9 , further comprising:
a primary channel extending in a longitudinal direction of the urinal.

13. The urinal of claim 9 , wherein the first side channel and the second side channels are symmetrical.

14. The urinal of claim 9 , wherein the urinal is formed from a vitreous material.

15. The urinal of claim 9 , wherein the first side channel and the second side channels are substantially symmetrical about a plane extending through the urinal.

16. A method of manufacturing a urinal, the method comprising:
filling a mold with a liquid slip, wherein the liquid slip sets up in the mold;
draining a remaining portion of the liquid through a drain channel;
removing at least one component of the mold;
closing the drain channel; and
baking the urinal in a kiln.

17. The method of manufacturing of claim 16 , further comprising:
forming a feature in the urinal.

18. The method of manufacturing of claim 16 , further comprising:
punching a hole in the urinal.

19. The method of manufacturing of claim 16 , wherein closing the drain comprises:
coupling a cap to the urinal using liquid slip.

20. The method of manufacturing of claim 16 , further comprising:
drying the urinal for a period of time before baking the urinal.
