Provided is a water purifier comprising: a filter unit which has a reverse osmosis membrane filter; a supply valve; an instantaneous heating device which is provided with an inflow port, and an outflow port, and which heats and purified water entering through the inflow port and flowing to the outflow port, so that hot water is discharged through the outflow port; an extraction member; a supply pump; a domestic water drain line; a hot water drain line; a hot water drain valve; and a control unit which controls the opening/closing of respective flow channels of the hot water drain line and the domestic water drain line so that, among a hot water draining process through the hot water drain line, and a domestic water draining process through the domestic water drain line, the hot water draining process is carried out first.

Water purifier

An ice-making water purifier includes a water tank unit, an instantaneous heating device, an extraction member, an ice-maker, a supply pump, an ice-making water inlet passage, an ice-making water supply valve, a flow rate sensor, and a controller configured to control driving of the supply pump and the opening and closing of the ice-making water supply valve such that purified water corresponding to a predetermined supply amount of ice-making water is supplied to the ice-maker on the basis of a flow rate value measured by the flow rate sensor. The controller controls the opening and closing of the channel such that purified water is preferentially supplied to the instantaneous heating device among the instantaneous heating device and the ice-maker.

Water purifier with ice-maker

A water treatment apparatus capable of sterilizing a storage tank and a sterilizing and cleansing method thereof are disclosed. The water treatment apparatus includes: a filter unit purifying raw water; a storage tank connected to the filter unit and storing purified water which has been filtered through the filter unit; an electrolytic sterilizer installed between the filter unit and the storage tank, electrolyzing only purified water which has been filtered through at least a portion of the filter unit to generate sterilization water, and supplying the sterilization water to the storage tank; a drain unit connected to the storage tank and discharging water accommodated in the storage tank; and a control unit controlling a water purification mode of the filter unit and a sterilization mode through the electrolytic sterilizer and the drain unit.
