Abstract

본 발명은 PTC 히터를 갖는 냉온수기와 그 동작제어방법에 관한 것으로, 일반적으로 온수통 내의 온수는 상온에서 적정온도, 예컨대 최저 85℃에서 최고 120℃의 온도 범위 내에서 유지되도록 온도 하강시 히터에 의해 가열되는데 온수가 사용됨에 따라 온수통 안으로 사용된 양만큼 새로이 유입되는 냉수의 신속한 가열이 곤란하므로 온수를 연속적으로 사용할 경우 배출되는 온수의 온도가 적정수준 이하로 떨어지는 단점을 가지고 있었다. 본 발명은 히터가 설치된 온수통의 바닥면에 설치되어 물을 급속가열할 수 있도록 되어 있는 PTC 히터, 온수통에 담겨진 물의 온도에 의해 히터와 PTC 히터가 선택적으로 동작되도록 이들의 동작을 제어하는 제어수단을 구성하되, 상기 제어수단은 온수통에 담겨진 물의 온도값을 검출할 수 있도록 되어 있는 온수통용 온도감지센서, 상기 온수통용 온도감지센서의 의해 검출된 온도값이 적정온도값의 하한치 이상으로 판정되면 히터만이 구동되도록 하고, 적정온도값의 하한치 이하로 판정되면 히터와 PTC 히터가 동시에 구동되도록 이들의 동작을 제어할 수 있는 마이크로 프로세서를 더 포함하여 이루어진 것이다.The present invention relates to a cold / hot water heater having a PTC heater and a method of controlling the operation thereof. Generally, hot water in a hot water tank is heated by a heater at a proper temperature, for example, As the hot water is heated, it is difficult to rapidly heat the fresh water flowing into the hot water tank. Therefore, when the hot water is continuously used, the temperature of the hot water discharged drops below a proper level. The present invention relates to a PTC heater installed on a bottom surface of a hot water tank provided with a heater and capable of rapidly heating water, a control unit for controlling the operation of the heater and the PTC heater so that the heater and the PTC heater are selectively operated by the temperature of water contained in the hot water tank Wherein the control means comprises a hot water temperature sensor for detecting the temperature of the water contained in the hot water tank, and a temperature sensor for detecting the temperature of the hot water tank, And a microprocessor capable of driving only the heater and controlling the operation of the heater and the PTC heater so that the heater and the PTC heater are simultaneously operated if it is determined that the temperature is lower than the lower limit value.
