Abstract
A method for controlling sterilization of a water purifier according to an embodiment of the present invention includes a housing accommodating components for generating cold water and/or hot water; a water chute which protrudes from a front surface of the housing and includes a water outflow part extending downward; and a light emitting element which is mounted inside the water chute corresponding to an upper end of the water outflow part and emits ultraviolet rays for sterilization, and the method includes when a sterilization mode is started, turning on the light emitting element for a first set time and to emit ultraviolet rays through the water outflow part; and after the lapse of the first set time, turning off the light emitting element for a second set time to stop emission of ultraviolet rays, in which a sterilization cycle is defined as a sum of the first set time and the second set time, in which the sterilization mode is started at the same time when the water purifier is powered on, and in which the first set time is set such that the sterilization mode is performed for one day so that the amount of ultraviolet rays emitted to the outside of the water outflow part is less than 3 mJ/cmduring the accumulated on time of the light emitting element.
