Abstract
An under-sink type water purifier with a water-tap portion connected to a purified-water outlet of the purifier having a sensor for sensing an object to issue a signal, and a solenoid valve for starting and stopping the discharge of purified water from the water-tap portion in response to the signal. The apparatus is characterized by a control circuit for opening and closing the valve in response to the signal. The circuit is provided with at least one of a first timer for opening the valve at every preset time for a short time, and a second timer for opening the valve for a short time to permit the water-tap portion to discharge the purified water therefrom when the purified water remains confined in the purifier for a predetermined period of time. These timers are selectively used in operation.
