1. An automatic flushing urinal (100) comprising:

  • (a) a urinal wall (110) with a top end (112), a bottom end (114) and an indentation (115) between the top end and the bottom end, wherein a urinal drainage port (118) is disposed on the bottom end to fluidly connect to a drain system (192);

    (b) at least one urine flow sensor (150) directly disposed on an inner surface (116) of the urinal wall (110), wherein the urine sensor functions to sense urine flow;

    (c) a hand washing sink (120) disposed above the top end (112) of the urinal wall (110), wherein the hand washing sink (120) has a sink drainage port (122) fluidly connected to the urinal wall indentation (115), wherein a water spout (130) is disposed on the hand washing sink (120) for water flow outlet into the hand washing sink (120); and

    (d) a controller (180), a timer (185), a power source (190) and a water valve (172);

    wherein the water valve (172) is fluidly connected to a water supply (170), wherein the controller (180) is operatively connected to the water valve (172), the timer (185), the power source (190) and the urine flow sensor (150);

    wherein the urine flow sensor (150) gets activated when it detects urine flow, wherein when urine stops flowing, the urine flow sensor (150) sends a first signal to the controller (180), whereupon receiving the first signal, the controller (180) sends a second signal to the water valve (172) to allow water flow from the water supply (170) through the water valve (172) and water spout (130);

    whereupon receiving the first signal, the controller (180) sends a third signal to the timer (185) to start time counting, the timer (185) sends back to the controller (180) a fourth signal after a first pre-determined period;

    whereupon receiving the fourth signal, the controller (180) sends a fifth signal to the water valve (172) to close the valve and stop water flow.
