Abstract

Claims (36)

1. A urinal, comprising:

a urinal body having a left sidewall, a right sidewall, and a rear wall extending from the left sidewall to the right sidewall; and

wherein the left sidewall has an interior surface, the right sidewall has an interior surface, the rear wall has an interior surface, and the interior surfaces of the left and right sidewalls and the rear wall, collectively, define an internal cavity of the urinal body, the internal cavity of the urinal body being in fluid communication with the bowl cavity,

wherein the rear wall of the urinal body includes at least two angled portions extending laterally inward and rearward from the left and right sidewalls, and the angled portions meet in a rounded corner of the rear wall,

wherein the at least two angled portions and the rounded corner are configured to deflect urine striking the rear wall such that the urine remains within the internal cavity of the urinal body and falls into the bowl cavity,

wherein the urinal body further includes a top portion disposed above the internal cavity of the urinal body and the top portion includes a plenum chamber defined by a front wall of the top portion, a top wall of the urinal body, a back wall of the urinal body, a lower wall of the top portion positioned above the rear wall, and the left and right sidewalls of the urinal body,

wherein the plenum chamber is configured to receive flush water via a top opening in the top wall of the urinal body and being in fluid communication with the internal cavity of the urinal body via a plurality of baffle holes formed in the lower wall of the top portion, and

wherein a flow restrictor is disposed within the plenum chamber to slow a velocity of water flowing through the plenum chamber to prevent splashing of water within the internal cavity of the urinal body and the bowl cavity.

2. The urinal according to claim 1 , wherein the flow restrictor comprises a baffle plate disposed within the plenum chamber that divides the plenum chamber into an upper portion and a lower portion, the baffle plate having at least one opening defined therein to allow water to flow from the upper portion of the plenum chamber to the lower portion of the plenum chamber.

3. The urinal according to claim 2 , wherein the baffle plate is configured to spread water evenly across the plurality of baffle holes formed in the lower wall of the top portion.

4. The urinal according to claim 1 , wherein the bowl has a substantially V-shape extending outwardly from the sidewalls.

5. The urinal according to claim 1 , wherein the shape of the bowl corresponds to a shape of the interior surfaces of the rear wall and the left and right sidewalls of the urinal body.

6. The urinal according to claim 1 , wherein the rounded corner of the rear wall is offset from a center of the urinal body.

7. A urinal, comprising:

a urinal body having a top portion, a left sidewall, a right sidewall, and a rear wall extending from the left sidewall to the right sidewall; and

a bowl disposed at a bottom of the urinal body, the bowl having a concave shape defining a bowl cavity,

wherein the left sidewall has an interior surface, the right sidewall has an interior surface, the rear wall has an interior surface, and the interior surfaces of the left and right sidewalls and the rear wall, collectively, define an internal cavity of the urinal body, the internal cavity of the urinal body being in fluid communication with the bowl cavity,

wherein the top portion of the urinal body includes a plenum chamber defined by a front wall of the top portion, a top wall of the urinal body, a back wall of the urinal body, a lower wall of the top portion positioned above the rear wall, and the left and right sidewalls of the urinal body, the plenum chamber being configured to receive flush water via a top opening in the top wall of the urinal body and being in fluid communication with the internal cavity of the urinal body via a plurality of baffle holes formed in the lower wall of the top portion, and

wherein a flow restrictor is disposed within the plenum chamber to slow a velocity of water flowing through the plenum chamber to prevent splashing of water within the internal cavity of the urinal body and the bowl cavity.

8. The urinal according to claim 7 , wherein the rear wall of the urinal body includes at least two angled portions extending laterally inward and rearward from the left and right sidewalls, and the angled portions meet in a rounded corner of the rear wall.

9. The urinal according to claim 8 , wherein the at least two angled portions and the rounded corner are configured to deflect urine striking the rear wall such that the urine remains within the internal cavity of the urinal body and falls into the bowl cavity.

10. The urinal according to claim 8 , wherein the rounded corner of the rear wall is offset from a center of the urinal body.

11. The urinal according to claim 8 , wherein the shape of the bowl corresponds to a shape of the interior surfaces of the rear wall and the left and right sidewalls of the urinal body.

12. The urinal according to claim 7 , wherein the bowl has a substantially V-shape extending outwardly from the sidewalls.

13. The urinal according to claim 7 , wherein the flow restrictor comprises a baffle plate disposed within the plenum chamber that divides the plenum chamber into an upper portion and a lower portion, the baffle plate having at least one opening defined therein to allow water to flow from the upper portion of the plenum chamber to the lower portion of the plenum chamber.

14. The urinal according to claim 13 , wherein the baffle plate is configured to spread water evenly across the plurality of baffle holes formed in the lower wall of the top portion.

15. A urinal, comprising:

a urinal body having a top portion, a left sidewall, a right sidewall, and a rear wall extending from the left sidewall to the right sidewall; and

a bowl disposed at a bottom of the urinal body, the bowl having a concave shape defining a bowl cavity,

wherein the left sidewall has an interior surface, the right sidewall has an interior surface, the rear wall has an interior surface, and the interior surfaces of the left and right sidewalls and the rear wall, collectively, define an internal cavity of the urinal body, the internal cavity of the urinal body being in fluid communication with the bowl cavity,

wherein the top portion of the urinal body includes a plenum chamber defined by a front wall of the top portion, a top wall of the urinal body, a back wall of the urinal body, a lower wall of the top portion positioned above the rear wall, and the left and right sidewalls of the urinal body, the plenum chamber being configured to receive flush water via a top opening in the top wall of the urinal body and being in fluid communication with the internal cavity of the urinal body via a plurality of baffle holes formed in the lower wall of the top portion,

wherein a flow restrictor is disposed within the plenum chamber to slow a velocity of water flowing through the plenum chamber to prevent splashing of water within the internal cavity of the urinal body and the bowl cavity,
