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 hot water supply method according to one embodiment of the present invention comprises the steps of: measuring a temperature of water flowing into an water inlet part; turning on a first heater and a second heater if a target temperature is a standard temperature or higher; adjusting a degree of opening and closing of a flow rate adjusting valve on the basis of a difference between the target temperature and the temperature of water flowing into the water inlet part; measuring a temperature of water discharged to a water outlet part; and readjusting the degree of opening and closing of the flow rate adjusting valve on the basis of a difference between the target temperature and the temperature of water discharged to the water outlet part.

Abstract: There is provided an instantaneous water heater capable of expelling heated water or steam when internal pressure reaches or exceeds a predetermined pressure, thus preventing an accident, product damage, or the like. The instantaneous water heater includes a main body having an inlet allowing water to be introduced therethrough and an outlet allowing water to be discharged therethrough; a heating unit disposed in the main body and heating water introduced to the main body; and a decompression unit connected to a decompression hole disposed in the main body and expelling heated water or steam to the outside thereof when internal pressure within the main body reaches or exceeds a predetermined pressure.

Abstract translation: 提供了当内部压力达到或超过预定压力时能够排出加热的水或蒸汽的瞬时热水器，从而防止事故，产品损坏等。 瞬时热水器包括主体，其具有允许水引入的入口和允许水通过其排出的出口; 加热单元，其设置在主体中并加热引入主体的水; 以及减压单元，连接到设置在主体中的减压孔，并且当主体内部压力达到或超过预定压力时，将加热的水或蒸汽排出到其外部。
