Abstract

A water purifier is provided. The water purifier according to an aspect of the present invention includes a housing; a filter provided inside the housing to filter raw water to produce purified water; a water outlet member that ejects purified water generated in the filter to the outside of the housing; a control valve configured to control water ejection amount ejected through the water outlet member; a factor value measurement sensor configured to obtain information on water ejection amount influencing factors that may affect the water ejection amount; an input panel provided on one side of the housing to receive input of at least one of first user input information to allow to be switched to a state where a user can set the water ejection amount, second user input information on a user water ejection amount which is a water ejection amount that the user wishes to set, and user water ejection start information to ensure that water is ejected as much as the user water ejection amount; and a processor configured to control the water ejection amount using information on the water ejection amount influencing factors when the user water ejection start information is input, wherein the processor may obtain a factor value at the time of setting of the water ejection amount influencing factor when the user water ejection amount is input, obtain a factor value at the time of water ejection of the water ejection amount influencing factor when the user water ejection amount is input, and control the control valve to eject water equal to the user water ejection amount using the factor value at the time of setting, the factor value at the time of water ejection, and the second user input information.
