PROBLEM TO BE SOLVED: To provide a urinal with a hand wash basin, capable of effectively washing a boundary part between urinary-stone-easily-sticking urea-mixed wash water and air.SOLUTION: The urinal with a hand wash basin connected to a draining horizontally-laid pipe comprises: a hand wash basin body having a hand wash water discharge part for discharging hand washing wash water, a hand wash bowl part, and a hand wash water drainage port formed in a bottom part of the hand wash bowl part; a urinal body having a toilet bowl water discharge part for discharging urea washing wash water, a toilet bowl part, and a toilet bowl water drainage port formed in a bottom part of the toilet bowl part; and a control part for controlling water discharge of the wash water from the hand wash water discharge part and the toilet bowl water discharge part. The control part measures a use frequency or a use time interval of the urinal with the hand wash basin, and almost simultaneously discharges water from both the hand wash water discharge part and the toilet bowl water discharge part when the use frequency or the use time interval arrives at a respectively predetermined measured value, and increases a flow rate per unit time of the wash water of flowing in the draining horizontally-laid pipe connected to the downstream side of a draining flow passage. |
