Patent attributes
A method of controlling a drinking water supply device includes inputting a water discharge signal through an input lever, opening a first valve such that drinking water flows through a first channel and measuring the amount of drinking water flowing through the first channel using a flow rate sensor, opening a second valve for a predetermined time to discharge minerals when the amount of drinking water measured by the flow rate sensor reaches a first predetermined amount, and, opening the second valve again for the predetermined time to further discharge minerals when a second predetermined amount of drinking water is measured by the flow rate sensor.
