WATER FEED DEVICE

PROBLEM TO BE SOLVED: To provide a water feed device which is easy to install and has excellent sensing performance if an automatic water faucet by simultaneously designing the both of the automatic water faucet and the washing bowl and also which has a new outer appearance so as to permit a user to normally comfortably wash hands. SOLUTION: The water feed device is provided with the washing bowl having a drain, with a water supply port which is connected to a water supply pipe and has a water supply port and with the automatic water faucet which has a sensor adjacently to the water supply port. A projection light from the sensor is reflected against the surface of the washing bowl and the automatic water faucet is attached to an upper part on the inner surface of the washing bowl so as to permit the reflection light to go out of the washing bowl surface. The shape of the washing bowl on the inner surface is formed to have a continuous and smooth airflow shape without having a partial swelling part by bending an upper side to have a projection when its cross section is vertically viewed from one side and bending a lower side to have a recession when its cross section is vertically viewed from one side.
