Abstract:
(EN) A hot water supply method, a hot water supply apparatus, and a water purifier including the same are disclosed. The hot water supply apparatus may comprise: a heater unit for heating feed water; a flow rate control unit for controlling the flow rate of water flowing through the heater unit; a flow rate sensor for measuring the flow rate of water flowing through the heater unit; a feed water temperature sensor disposed at the front end of the heater unit so as to measure the temperature of water fed into the heater unit; a current sensing unit for sensing a current flowing through the heater unit; and a control unit which, when hot water is initially dispensed, operates the heater unit, calculates a target flow rate value by using a current value measured by the current sensing unit and a feed water temperature value measured by the feed water temperature sensor, controls the flow rate control unit such that a flow rate value measured by the flow rate sensor corresponds to the target flow rate value, acquires a flow rate control value at the time when the measured flow rate value corresponds to the target flow rate value, and sets the acquired flow rate control value as an initial control value, wherein the control unit updates the initial control value on the basis of at least one of a measured feed water temperature value, a measured flow rate value, and a calculated power value of the heater unit, which are obtained in a standby state where hot water dispensing is not performed after the initial hot water dispensing.
(FR) L'invention concerne un procédé d'alimentation en eau chaude, un appareil d'alimentation en eau chaude et un purificateur d'eau comprenant ledit procédé et ledit appareil. L'appareil d'alimentation en eau chaude peut comprendre : une unité de chauffage destinée à chauffer de l'eau d'alimentation ; une unité de régulation de débit destinée à réguler le débit d'eau coulant à travers l'unité de chauffage ; un capteur de débit destiné à mesurer le débit d'eau coulant à travers l'unité de chauffage ; un capteur de la température de l'eau d'alimentation disposé au niveau de l'extrémité avant de l'unité de chauffage afin de mesurer la température de l'eau alimentée à l'unité de chauffage ; une unité de détection de courant destinée à détecter un courant circulant à travers l'unité de chauffage ; et une unité de commande destinée, lorsque de l'eau chaude est initialement distribuée, à actionner l'unité de chauffage, à calculer une valeur de débit cible au moyen d'une valeur de courant mesurée par l'unité de détection de courant et d'une valeur de température de l'eau d'alimentation mesurée par le capteur de la température de l'eau d'alimentation, à commander l'unité de régulation de débit de sorte qu'une valeur de débit mesurée par le capteur de débit corresponde à la valeur de débit cible, à acquérir une valeur de régulation de débit au moment où la valeur de débit mesurée correspond à la valeur de débit cible, et à régler la valeur de régulation de débit acquise en tant que valeur de régulation initiale. L'unité de commande met à jour la valeur de régulation initiale en fonction d'une valeur de la température de l'eau d'alimentation mesurée, et/ou d'une valeur de débit mesurée, et/ou d'une valeur de puissance calculée de l'unité de chauffage, obtenues en mode en veille lors de l'absence de distribution d'eau chaude après la distribution initiale d'eau chaude.
(KO) 온수 공급 방법, 온수 공급 장치 및 이를 포함하는 정수기가 개시된다. 상기 온수 공급 장치는, 유입되는 물을 가열하는 히터부; 상기 히터부를 통해 흐르는 물의 유량을 조절하는 유량 제어부; 상기 히터부를 통해 흐르는 물의 유량을 측정하는 유량 센서; 상기 히터부의 전단에 구비되어 상기 히터부로 유입되는 물의 온도를 측정하는 입수 온도 센서; 상기 히터부에 흐르는 전류를 감지하는 전류 감지부; 및 최초 온수 추출시에, 상기 히터부를 구동시키고 상기 전류 감지부에 의해 측정된 전류값 및 상기 입수 온도 센서에 의해 측정된 입수 온도값을 이용하여 목표 유량값을 산출하고, 상기 유량 센서에 의해 측정된 유량값이 상기 목표 유량값과 일치되도록 상기 유량 제어부를 제어하며, 상기 측정된 유량값이 상기 목표 유량값과 일치하는 시점의 유량 제어값을 획득하여 초기 제어값으로 설정하는 제어부를 포함할 수 있으며, 상기 제어부는 최초 온수 추출 이후 온수 추출을 하지 않는 대기 상태에서 측정된 입수 온도값, 유량값 및 산출된 히터부의 전력값 중 적어도 하나를 기초로 상기 초기 제어값을 갱신할 수 있다.
