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.

Sterilization control method of water purifier

A water purifier according to an embodiment of the present invention may include a housing accommodating components for generating cold water and/or hot water; a water cock which protrudes from a front surface of the housing, the water cock being configured to discharge the cold water or the hot water; a control panel which is provided so as to input a command for discharging the cold water or the hot water; a sterilization module which is detachably mounted on the water cock, the sterilization module being configured to emit ultraviolet rays for sterilizing the inside of the water cock; and a fastening part which is formed on the water cock and the sterilization module, respectively, so that the sterilization module can be attached to and detached from the water cock.

Ultraviolet module and liquid dispenser including same

The present invention provides a method for controlling a drinking-water supply device, the method comprising: a first step of connecting a guide pipe of a case separated from a cabinet to form a channel through which water moves from the case to the cabinet; a second step of supplying the cabinet with hot water heated by a second hot water module included in the case; and a third step of supplying the cabinet with water which has not passed through the second hot water module included in the case, wherein a first hot water module, included in the cabinet, for heating water is not driven in the second step and the third step.

Drinking liquid supply device and method for controlling same

A water purifier that includes: a water storage tank that includes an interior area and a first opening to the interior area; a cover unit that is configured to cover the first opening and that includes: a frame body that includes a second opening, and a water storage tank cover that is coupled to the frame body and that is configured to rotate about an axis such that the water storage tank cover opens or closes the second opening; a sterilizer that is configured to sterilize water in the water storage tank; a switching module that is configured to control electric power supply to the sterilizer; and an operation member that is configured to control the switching module based on the water storage tank cover being opened or closed is disclosed.

Water purifier

A sterilizing system according to the present invention includes a water supply apparatus provided with a filter unit having a plurality of filters, a water tank storing water purified by the filter unit, a water cock and water tank connection passages, and a sterilizer to sterilize the water supply apparatus, wherein the sterilizer comprises a sterilizing water generator, a circulation pump, a circulation passage, a rinsing water supply passage, a first drain passage and a first drain valve.
