냉온수 공급기기{HOT AND COLD WATER DISPENSER}Cold and hot water supply equipment {HOT AND COLD WATER DISPENSER}

본 발명은 자유피스톤 스터링쿨러를 이용한 냉,온수 공급기기에 관한 것으로, 특히 스터링쿨러의 흡열부를 냉수통과 연계시키는 반면 발열부는 온수통과 연계시켜 냉,온수를 손쉽게 제공하는 냉온수 공급기기에 관한 것이다.The present invention relates to a cold and hot water supply device using a free piston sterling cooler, and more particularly, to a cold and hot water supply device that associates the heat absorbing portion of the sterling cooler with a cold water tank while providing a cold and hot water easily in connection with a hot water tank.

일반적으로 냉온정수기나 또는 냉온자동판매기 등에 사용되는 냉,온수 공급장치는, 주로 열전모듈(Theroelectric)이나, 또는 냉매압축식 냉동사이클장치를 이용하고 있는 실정이다.Generally, cold and hot water supply apparatuses used in cold / hot water purifiers, cold / hot water vending machines, etc. mainly use a thermoelectric module or a refrigerant compression refrigeration cycle apparatus.

이 중에서 먼저, 열전모듈을 이용하는 경우는 도 1에 도시된 바와 같이, 소정의 급수원에 연결된 급수관(1)은 냉수통(2) 및 온수통(3)으로 각각 분관되어 있고, 그 냉수통(2)과 온수통(3)의 사이에는 전류공급으로 흡열 및 발열작용을 하는 열전모듈(4)이 밀착 개재되어 있는데, 상기 열전모듈(4)의 흡열부(4a)는 냉수통(2)의 일측면에 밀착되는 반면에 발열부(4b)는 온수통(3)의 일측면에 밀착되어 있다.Among these, first, in the case of using a thermoelectric module, as shown in FIG. 1, the water supply pipe 1 connected to a predetermined water supply source is branched into a cold water tank 2 and a hot water tank 3, respectively, and the cold water tank ( Between the 2) and the hot water tank (3) is interposed between the thermoelectric module (4) for the endothermic and exothermic action by the current supply, the endothermic portion (4a) of the thermoelectric module (4) of the cold water tank (2) While closely contacted on one side, the heat generating portion 4b is in close contact with one side of the hot water tank (3).

이러한, 냉,온수 공급기기에 DC전원이 인가되면, 흡열부(4a)안의 P형 반도체에서는 상부전극으로부터 하부전극으로 양전하(+)가 흐르게 되는 반면, 발열부(4b)안의 N형 반도체에서는 상부전극으로부터 하부전극으로 음전하(-)가 흐르게 되어, 상기 흡열부(4a)에서는 냉수통(2)의 물을 차게 하는 반면, 발열부(4b)에서는 온수통(3)의 물을 데펴주게 되는 것이었다.When the DC power is applied to the cold and hot water supply device, positive charge (+) flows from the upper electrode to the lower electrode in the P-type semiconductor in the heat absorbing portion 4a, while the upper portion is formed in the N-type semiconductor in the heat generating portion 4b. The negative charge (-) flows from the electrode to the lower electrode, so that the water in the cold water tank 2 is filled in the heat absorbing portion 4a, while the water in the hot water container 3 is heated in the heat generating portion 4b. .

한편, 별도로 도시하지는 않았으나, 냉매압축식 냉동사이클장치를 이용하는 경우는, 냉수통(미도시)과 온수통(미도시)의 사이에 통상적인 냉매압축식 냉동사이클장치(미도시)를 설치하는 것으로, 그 냉매압축식 냉동사이클장치의 증발기는 냉수통의 외주면에 감싸져 증발시 냉수통으로부터 열을 흡수하는 반면, 응축기는 온수통의 외주면에 감싸져 응축시 온수통으로 열을 방출하는 것이었다.On the other hand, although not shown separately, in the case of using a refrigerant compression refrigeration cycle apparatus, by installing a conventional refrigerant compression refrigeration cycle apparatus (not shown) between the cold water tank (not shown) and the hot water tank (not shown). The evaporator of the refrigerant compression refrigeration cycle apparatus was wrapped on the outer circumferential surface of the cold water tank to absorb heat from the cold water tank during evaporation, while the condenser was wrapped on the outer circumferential surface of the hot water tank to release heat to the hot water tank during condensation.

그러나, 상기와 같은 종래의 냉온수 공급기기에서 먼저, 열전모듈(4)을 이용하는 경우는 구조적으로 열전달은 용이하나, 실제 열전달율은 매우 낮아 충분한 냉수 및 온수를 제공하는데 한계가 있었고, 반면 냉매압축식 냉동사이클장치를 이용하는 경우에는 그 사이클장치가 차지하는 공간이 비대하게 되는 것은 물론 소음 및 진동이 발생되는 문제점이 있었다.However, in the conventional cold and hot water supply apparatus as described above, when the thermoelectric module 4 is used, heat transfer is structurally easy, but the actual heat transfer rate is very low, thereby providing a sufficient amount of cold water and hot water. In the case of using a cycle device, the space occupied by the cycle device becomes large, as well as noise and vibration.

따라서, 본 발명은 상기와 같은 종래의 냉온수 공급기기가 가지는 문제점을 감안하여 안출한 것으로, 열전달이 용이하면서도 그 효율이 높고, 필요공간이 작아 기기의 소형화가 가능하며, 소음 및 진동이 최소화된 냉온수 공급기기를 제공하는데 본 발명의 목적이 있다.Accordingly, the present invention has been made in view of the problems of the conventional cold and hot water supply device as described above, the heat transfer is easy and its efficiency is high, and the required space is small, the device can be miniaturized, the noise and vibration is minimized cold and hot water It is an object of the present invention to provide a feeder.
