Urinal having a sink to minimize water usage in lavatories

Abstract

A urinal having a sink to minimize water usage in lavatories is disclosed. The urinal includes a top end portion and a bottom end portion. A bowl is positioned at the bottom end portion and a rear wall is disposed at rear portion of the bowl to allow water to fall down the rear wall and into the bowl. Additionally, the urinal includes a sink disposed at the top end portion of the urinal. The sink has a sink opening at a sink bottom end portion and above the rear wall where the sink opening provides fluid opening between the sink opening and the rear wall. When the urinal is flushed, water that is dispensed into the sink is used to flush wastewater out of the bottom end portion of the bowl.

We claim: 
     
         1 . A urinal comprising:
 a top end portion and a bottom end portion;   a bowl disposed at the bottom end portion;   a rear wall disposed at rear portion of the bowl and configured such that water falls down the rear wall and into the bowl;   a sink disposed at the top end portion of the urinal;   a sink opening at a sink bottom end portion and above the rear wall; and   wherein the sink opening provides fluid communication between the sink opening and the rear wall.   
     
     
         2 . The urinal of  claim 1 , wherein the urinal further comprises a water dispensing element at least proximate to the sink configured to dispense a fluid into the sink. 
     
     
         3 . The urinal of  claim 2 , wherein the urinal further comprises a urinal opening at the bottom end portion of the urinal configured to allow fluid to move out of the bottom end portion of the urinal. 
     
     
         4 . The urinal of  claim 3 , wherein the sink opening comprises an elongated shaped opening. 
     
     
         5 . The urinal of  claim 4 , wherein the sink extends frontward relative to the rear wall. 
     
     
         6 . The urinal of  claim 5 , wherein the urinal further comprises a first sensor configured for sensing if at least hands of a user is proximate to the water dispensing element. 
     
     
         7 . The urinal of  claim 6 , wherein the urinal further comprises a processor configured for receiving a first signal from a sensor if at least said hands of the user is proximate to the water dispensing element and sending a second signal to cause fluid to be dispensed from the water dispensing element. 
     
     
         8 . The urinal of  claim 7 , wherein the urinal is configured to automatically flush at a predetermined time. 
     
     
         9 . The urinal of  claim 8 , wherein the urinal is in fluid communication with a drainage conduit. 
     
     
         10 . A urinal comprising:
 a top end portion and a bottom end portion;   a bowl disposed at the bottom end portion;   a rear wall disposed at rear portion of the bowl and configured such that water falls down the rear wall and into the bowl;   a sink disposed at the top end portion of the urinal;   a sink opening at a sink bottom end portion and above the rear wall;   a water dispensing element at least proximate to the sink configured to dispense a fluid into the sink; and   wherein the sink opening provides fluid communication between the sink opening and the rear wall.   
     
     
         11 . The urinal of  claim 10 , wherein the urinal further comprises a urinal opening at the bottom end portion of the urinal configured to allow the fluid to move out of the bottom end portion of the urinal. 
     
     
         12 . The urinal of  claim 10 , wherein the sink opening is proximate to the rear wall. 
     
     
         13 . The urinal of  claim 10 , wherein the sink extends frontward relative to the rear wall. 
     
     
         14 . A urinal comprising:
 a sink disposed at a top end portion of the urinal;   a sink opening at a sink bottom end portion and proximate to a vertical wall of the urinal; and   wherein the sink opening provides fluid communication between the sink opening and the vertical wall.   
     
     
         15 . The urinal of  claim 14 , wherein the urinal further comprises a first sensor configured for sensing if at least hands of a user is proximate to a water dispensing element. 
     
     
         16 . The urinal of  claim 15 , wherein the urinal further comprises a processor configured for receiving a first signal from a sensor if the at least hands of the user is proximate to the water dispensing element and sending a second signal to cause a fluid to be dispensed from the water dispensing element. 
     
     
         17 . The urinal of  claim 16 , wherein the urinal is configured to automatically flush at a predetermined time. 
     
     
         18 . The urinal of  claim 14 , wherein the urinal further comprises a water dispensing element at least proximate to the sink configured to dispense fluid into the sink. 
     
     
         19 . The urinal of  claim 18 , wherein the urinal further comprises a urinal opening at a bottom end portion of the urinal configured to allow the fluid to move out of the bottom end portion of the urinal. 
     
     
         20 . The urinal of  claim 19 , wherein the fluid dispensed into the sink flushes wastewater out of the urinal opening.
