Abstract: 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.

Abstract: 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.

Abstract: A water purifier is provided. A water purifier according to one aspect of the present invention may include a housing having a first accommodation space therein, and made of a paper material; a water purifier faucet disposed in the first accommodation space to receive raw water and discharge purified water; and a filter coupled to the water purifier faucet to generate the purified water by filtering the raw water, wherein the water purifier faucet includes a base frame having a second accommodation space therein in which the filter is accommodated; a water inlet module provided on one side of the base frame to supply raw water introduced from the outside to the filter; and a water outlet module provided on the other side of the base frame to receive the purified water generated by the filter and discharge it to the outside.
