Description

음용액체 냉각장치의 냉각구조Cooling structure of drinking liquid cooling device

본 고안은 일반가정이나 사무실 및 공공장소에서 사용되어지는 정수기나 기타 음료냉각기등에서 물통에 저장된 음용액체를 차갑게 냉각하여 냉수를 얻을 수 있도록 하는 냉각구조의 구성과 그 방식에 관한 음용액체 냉각장치에 관한 것으로써, 음용액체 저장물통 내부에 이중관 구조의 냉매코일을 삽입하여 냉각효율의 극대화와 이로인한 전기소모량을 줄이고 음용액체의 안전성을 최대한 확보하며, 냉각구조를 간편하게 하여 작업성을 향상시킨 음용액체 냉각장치의 냉각구조에 관한 것이다.The present invention relates to the structure of the cooling structure for cooling the drinking liquid stored in the water tank and to the cold water in the water purifier or other beverage coolers used in general homes, offices and public places, and the drinking liquid cooling apparatus for the method. By inserting the double-pipe refrigerant coil inside the drinking liquid reservoir, the cooling efficiency is maximized, thereby reducing the amount of electricity consumption, ensuring the safety of the drinking liquid, and simplifying the cooling structure. It relates to a cooling structure of the device.

통상적으로 사용되어지는 음용액체 냉각장치의 냉각방식에는 크게 두가지의 방식이 사용되고 있는데, 그 첫째는 프레온가스를 이용한 압축기(콤프레샤)방식이고, 둘째로는 펜티에효과를 응용하여 열전반도체소자를 이용한 열전소자(썸머모듈)방식이 있다. 상기의 두가지 방식중 열전소자방식의 경우 냉각효율이 압축기 방식보다 현저히 떨어지는 관계로 아직 실용화 단계까지는 이르지 못하고 있는 실정이며, 따라서 오래전부터 안전성 및 냉각효율면에서 뛰어난 성능이 입증된 압축기를 사용한 냉각방식이 사용되고 있다.Two methods are commonly used for the cooling method of a drinking liquid cooling device which is commonly used. The first is a compressor (compressor) using freon gas, and the second is a thermoelectric using a thermoelectric semiconductor element by applying a Pentier effect. There is a device (summer module) method. Among the above two methods, the thermoelectric device method has not been reached until the practical stage because the cooling efficiency is significantly lower than that of the compressor method. Therefore, the cooling method using the compressor which has proven the excellent performance in terms of safety and cooling efficiency for a long time is It is used.

하지만, 제1도에 도시되어 있는 바와 같이 종래의 압축기 냉각방식에 있어서는 물통(10)안의 물온도를 떨어뜨리기 위해서 스테인레스 또는 알루미늄으로 이루어진 물통(10)의 외벽(11)에 냉매코일(14)을 감아 고압의 압축기로 냉매가스를 압축하여 액체상태의 냉매가스를 가는 모세관을 지나가게 하여 기화시키고, 기화된 냉매가스가 물통(10)의 외벽(11)에 감겨진 냉매코일(14)을 통과하는 도중에 물통(10)의 물의 온도와 냉매코일(14) 온도간의 열교환이 이루어지게 하여 궁극적으로 물통(10)내의 물의 온도를 떨어뜨리는 것이다. 그러나 상기와 같은 종래의 압축기 냉각방식은 아래와 같은 여러 가지 문제점들을 안고 있었다.However, as shown in FIG. 1, in the conventional compressor cooling method, the refrigerant coil 14 is disposed on the outer wall 11 of the bucket 10 made of stainless steel or aluminum in order to lower the water temperature in the bucket 10. The refrigerant gas is compressed by a high-pressure compressor to pass through a capillary tube that passes the liquid refrigerant gas to vaporize, and the vaporized refrigerant gas passes through the refrigerant coil 14 wound on the outer wall 11 of the water tank 10. On the way, the heat exchange between the temperature of the water in the bucket 10 and the temperature of the refrigerant coil 14 is made, which ultimately lowers the temperature of the water in the bucket 10. However, the conventional compressor cooling method has had various problems as follows.

첫째, 냉매코일(14)과 물통(10)의 외벽(11), 물통(10)의 외벽(11)과 물과의 열교환이 이루어지는데, 이때 외벽(11)이 상호 열교환을 하는데 있어 방해하는 역할을 하므로 열교환이 더디고 중간에 열손실이 발생하였으며, 둘째, 물통(10)의 외벽(11)에 냉매코일(14)을 감게될 경우, 원통형의 냉매코일(14)과 물통(10)의 외벽(11)이 접촉하고, 이때 접촉되는 부분이 극히 일부분만 접촉하게 되어 냉매코일(14)이 갖고 있는 열량중 극히 일부분만 열교환이 이루어지고 대부분의 열량이 손실되었으며, 셋째, 냉매코일(14)을 아래에서 위로 감을 경우, 물통(10) 아래부분의 물 온도는 매우 차가우나 위로 올라 갈수록 물의 온도는 차갑지 않게 되어 물통(10)의 아랫부분의 일정량이 나온 후에는 미지근한 물이 나오게 되어, 결국 물통(10)의 크기를 키우거나 압축기의 용량을 늘릴 수밖에 없어 비효율적인 구조를 이루었으며, 넷째, 냉매코일(14)을 물통(10) 외주연으로 감을 때 냉매코일(14)이 꺾이지 않게 하기 위하여 항상 물통(10)을 원통형으로 제작할 수 밖에 없어 물통(10)의 모양을 제품내의 공간상황에 맞게 또는 유효적절하게 모양변경을 할 수가 없는 불편한점이 발생하였으며, 다섯째, 물통(10) 외벽(11)에 냉매코열(14)을 감는 불편한 작업성을 갖고 있어 양산성이 떨어지고 원가상승의 요인이 발생하였으며, 여섯째, 현재까지 사용되는 물통(10)은 인체에 해가 없고 열교환 장애가 없는 스텐레스 재질을 사용하는데 이는 단가상승에 큰 영향을 미치케 되었다.First, the heat exchange between the refrigerant coil 14 and the outer wall 11 of the bucket 10, the outer wall 11 of the bucket 10 and water is performed, in which the outer wall 11 interferes in mutual heat exchange. Since heat exchange is slow and heat loss occurs in the middle, and second, when the refrigerant coil 14 is wound on the outer wall 11 of the bucket 10, the cylindrical refrigerant coil 14 and the outer wall of the bucket 10 ( 11) is in contact with, at this time, only a part of the contact portion is in contact with each other, only a fraction of the heat of the refrigerant coil 14 is heat exchanged, most of the heat was lost, third, the refrigerant coil 14 is below If you wind up at the bottom of the water tank 10, the water temperature is very cold, but as the temperature rises, the temperature of the water does not become cold, and after a certain amount of the lower part of the water bottle 10, lukewarm water comes out. ) Or increase the capacity of the compressor Fourth, in order to prevent the refrigerant coil 14 from bending when the refrigerant coil 14 is wound around the outer periphery of the bucket 10, the bucket 10 can always be manufactured in a cylindrical shape. 10) There is an inconvenient point that the shape of the product can not be changed to suit or effectively fit the space situation in the product, and fifth, it has an inconvenient workability of winding the refrigerant coil 14 on the outer wall 11 of the bucket (10) Sixth, the bucket 10 used to date is made of stainless material without harm to human body and no heat exchange failure, which has a great effect on the unit cost rise.

본 고안은 상기와 같은 종래의 제반 문제점을 해결하기 위하여 안출된 것으로, 음용액체 저장물통 내곡에 이중관 구조의 냉매코일을 삽입하여 냉각효율의 극대화와 이로인한 전기소모량을 줄이고 음용액체의 안전성을 최대한 확보하며, 냉각구조를 간편하게하여 작업성을 향상시킨 음용액체 냉각장치의 냉각구조를 제공하고자 하는데 본 고안의 목적이 있다.The present invention was devised to solve the above-mentioned conventional problems, by inserting the refrigerant coil of the double pipe structure into the inner bowl of the drinking liquid storage container to maximize the cooling efficiency and thereby reduce the amount of electricity consumption and ensure the safety of the drinking liquid to the maximum. And, to provide a cooling structure of the drinking liquid cooling device to improve the workability by simplifying the cooling structure is an object of the present invention.

상기와 같은 목적을 달성하기 위히여, 본 고안에서는 냉매코일인 동관을 물통내부로 삽입하여 음용액체와 직접 접촉하도록 하여 물통내의 물을 효율적으로 냉각시킬 수 있도록 하였으며, 삽입된 냉매코일을 상단에서 하단 방향으로 코일을 감아줌으로써 물통내의 상·하 구분없이 전체적으로 물을 차갑게 시킬수가 있어 따로 압축기의 용량을 늘리지 않아도 되며, 상기의 물통내부로 삽입된 냉매코일의 안전성을 확보하기 위하여 냉매코일을 스테인레스 관으로 감싸주는 이중관을 사용하였으며, 또한 냉매코일이 물통내부로 삽입되어짐으로써 냉수통의 외형을 자유롭게 제작할 수가 있어 제품외부의 공간활용폭을 증대하였으며, 물통 외벽으로 냉매코일을 감을 필요가 없어 작업성이 향상되고 원가절감을 가져올수 있으며, 이로인한 본 고안의 냉각시스템에서는 물통의 재질 선정에 전혀 구애를 받지 않게 되어 스텐레스가 아닌 플라스틱 물통을 사용할 경우 원가부분을 낮출 수가 있어 경제적인 시스템을 갖춘 음용액체 냉각장치의 냉각구조를 제공하고자 하는 것이다.In order to achieve the above object, in the present invention, the copper tube, which is the refrigerant coil, is inserted into the water tank so as to be in direct contact with the drinking liquid so that the water in the water tank can be efficiently cooled. By winding the coil in the direction, it is possible to cool the whole water without any distinction between the top and bottom of the water tank. Therefore, it is not necessary to increase the capacity of the compressor separately. The use of a double pipe to wrap and also the refrigerant coil can be inserted into the inside of the water tank, which makes the appearance of the cold water tank freely, increasing the space utilization of the outside of the product. It can bring down the cost, and when cooling the present invention The stem is not subject to the material selection of the bucket at all, and it is possible to lower the cost portion when using a plastic bucket other than stainless steel, and to provide a cooling structure of the drinking liquid cooling device equipped with an economical system.

본 고안은 제2도와 제3도에 도시된 바와 같이 냉매코일(24)을 물통내부(25)로 삽입하여 냉각효율을 향상시키고자 하였으며, 또한 동관으로 된 냉매코일(24) 외부에 스테인레스관(27)을 씌워 삽입하였다.The present invention is to improve the cooling efficiency by inserting the refrigerant coil 24 into the water tank inner portion 25 as shown in Figure 2 and 3, and also the stainless steel tube ( 27) and inserted.

냉매코일(24)의 물통내부(25)로의 유입부(22)는 상부에서부터 증발이 시작되어 하부로 내려와서 유출구(23)로 빠져나가는 구조로 형성되어 있으며, 상부와 하부의 냉매코일의 반경을 제2도와 같이 동일하게 하거나 제3도에 도시된 바와 같이 상단에서는 큰 회전반경으로 이루어지고 하단으로 내려오면서 회전반경이 줄어 들도록 구성되어진다.The inlet portion 22 of the coolant coil 24 into the water tank inner portion 25 is formed in a structure in which evaporation starts from the top and descends to the bottom to exit the outlet 23. As shown in FIG. 2 or as shown in FIG. 3, the upper end has a larger radius of rotation and is configured to decrease the lower radius of rotation as it descends to the lower side.

본 고안의 특징은 물통내부(25)로의 냉매코일(24)을 직접 삽입하는 것으로, 물통내부(25)에 위치한 냉매코일(24)에 해당하는 부분에는 냉매코일(24) 내부의 냉매가 동관의 균열이나 기타 외부충격등에 의해 음용액체로 흘러 들어와 인체에 해가 되는 것을 방지하기 위하여 냉매코일(24) 외측 둘레에 스테인레스관(27)을 씌워 이중관 구조로 하여 안전성을 최대한 확보하였으며, 상기 냉매코일(24)과 스테인레스관(27) 사이에는 열전도를 향상시키기 위하여 구리스(28)를 주입하였다.A feature of the present invention is to insert the refrigerant coil 24 directly into the bucket 25, the portion corresponding to the refrigerant coil 24 located in the bucket 25, the refrigerant inside the refrigerant coil 24 of the copper tube In order to prevent damage to the human body by flowing into the drinking liquid by cracks or other external shock, etc., the stainless steel pipe 27 is covered with the outer circumference of the refrigerant coil 24 to double the structure to secure the maximum safety. Between the 24) and the stainless steel pipe 27, a grease 28 was injected in order to improve thermal conductivity.

상기와 같이 냉매코일(24)을 물통내(25)로 직접 삽임함으로써 냉매코일(24)의 외측전둘레의 면적과 음용액체가 직접 접촉을 하므로써 물통외벽에 의한 열손실을 줄이고 열효율을 극대화 시켰으며, 물통내부(25)에서의 상·하 온도편차를 줄이고 전체적으로 차갑게 시킬수 있도록 하기 위하여 유입구(22)로부터 들어오는 냉매는 상부에서 하부로 내려오도록 구성되여지고, 특히, 상부의 냉매코일(24)의 회전반경은 크게, 하부로 내려올수록 냉매코일(24)의 회전반경은 작게 형성되도록 하였다.By inserting the coolant coil 24 directly into the bucket 25 as described above, the area of the outer periphery of the coolant coil 24 is directly in contact with the drinking liquid, thereby reducing heat loss caused by the bucket outer wall and maximizing thermal efficiency. In order to reduce the temperature difference between the upper and lower temperatures in the water tank 25 and to cool the whole, the refrigerant coming from the inlet 22 is configured to descend from the upper part to the lower part, and in particular, the rotation of the upper refrigerant coil 24. The larger the radius, the lower the radius of rotation of the refrigerant coil 24 as it descends.

한편, 본 고안은 냉매코일(24)이 물통내부(25)로 직접 삽입되는 구조를 이룸으로써 물통의 외형을 자유롭게 형성할 수가 있으며, 제품 내외부의 공간활용폭을 증대시키고 작업성을 향상할 수 있으며, 고가의 냉매코일(14, 24)이 저장물통(10,20)의 외측둘레로 감겨지는 종례의 실시예에 비해 최소화하므로써 원가절감을 가져올 수 있으며, 스테인레스관으로 제작되어지는 물통(10, 20)을 저가의 플라스틱재로 물통(10, 20)의 재질변경이 가능함으로써 이로인한 원가를 절감할 수 있는 장점을 가지는 것이다.On the other hand, the present invention by forming a structure in which the refrigerant coil 24 is inserted directly into the bucket 25, it is possible to freely form the appearance of the bucket, to increase the space utilization of the inside and outside of the product and improve the workability, Expensive refrigerant coils (14, 24) can be reduced by minimizing the cost compared to the embodiment of the case that is wound around the outer periphery of the reservoir (10, 20), and made of stainless steel pipe (10, 20) This is because it is possible to change the material of the bucket (10, 20) with a low-cost plastic material has the advantage of reducing the cost.

상기와 같은 구성으로 된 본 고안의 작용효과는 냉매코일을 물통내부로 삽입함으로써 냉매코일의 외측 전둘레에 의한 열교환 면적증대를 통하여 냉각효율을 크게 향상할 수가 있으며, 냉매코일의 물통 내부로의 삽입으로 종래의 물통외측 둘레에 감겨지던 냉매코일의 양이 줄어들고, 작업성 향상을 가져오며, 이로인한 기존의 스테인레스재질의 물통에서 플라스틱재질의 물통로 변경이 가능하여 탱크재질의 선정에 전혀 구애받지 않아도 되며 원가도 절감할 수 있으며, 물통내부로 삽입된 냉매코일 외주연에 스테인레스관을 씌워 이중관구조를 형성함으로써 하나의 냉매코일만 삽입하였을 경우 냉매가 유출되는 위험성을 배제하여 음용액체의 안전성을 최대한 보장함으로써 기능과 냉각효율면에서 월등한 음용액체 냉각장치의 냉각구조가 제공되어지는 것이다.The working effect of the present invention having the above structure can greatly improve the cooling efficiency by increasing the heat exchange area by the outer edge of the refrigerant coil by inserting the refrigerant coil into the bucket, and inserting the refrigerant coil into the bucket. As a result, the amount of refrigerant coil wound around the outer side of the conventional water tank is reduced, and workability is improved, and thus, it is possible to change from the conventional stainless steel bucket to the plastic bucket, so that it is not required to select the tank material at all. Also, cost can be reduced, and double pipe structure is formed by covering stainless steel pipe on the outer circumference of the refrigerant coil inserted into the bucket to eliminate the risk of leakage of refrigerant when only one refrigerant coil is inserted to ensure the safety of drinking liquid. By providing a cooling structure of drinking liquid cooling device which is superior in function and cooling efficiency. It is.
