냉매·발열히터 파이프 고정구조{PIPE FIXING STRUCTURE FOR WATER PURIFIER}Refrigerant heating element pipe fixed structure {PIPE FIXING STRUCTURE FOR WATER PURIFIER}

본 발명은 냉매·발열히터 파이프 고정구조에 관한 것으로, 더욱 상세하게는 정수기나 냉온수기의 저수통에 저수된 물을 직접 냉각하거나 가열하는 냉매 파이프나 발열히터 파이프를 저수통의 적소에 고정하는 냉매·발열히터 파이프 고정구조에 관한 것이다.The present invention relates to a refrigerant / heating heater pipe fixing structure, and more particularly, to a refrigerant pipe or a heating heater pipe that directly cools or heats water stored in a reservoir of a water purifier or a cold / hot water heater. An exothermic heater pipe fixing structure.

인간은 누구나 장수하기를 원하며, 건강하게 장수하고 싶은 욕망은 깨끗한 물에 대한 관심도에서도 엿볼 수 있다. 근래들어 염소로 소독된 수돗물은 설거지나 세탁, 청소하는데 주로 사용되고 있고, 식수로는 생수나 미네럴워터 등이 많이 사용되고 있다.Everyone wants to live longer, and the desire to live longer can be seen in the interest in clean water. Recently, tap water sterilized with chlorine is mainly used for washing dishes, washing and cleaning, and drinking water and mineral water are used for drinking water.

생수나 미네럴워터 등은 식음료회사에서 만들어진 것을 마트 등에서 구입하여 마셔야 하기 때문에 경제적인 부담이 있고, 구입을 위해 마트를 방문해야 하는 불편함이 있다.Bottled water and mineral water is economical burden because you have to buy and drink made in food and beverage companies, such as marts, there is an inconvenience to visit the mart for purchase.

이에 가정이나 사무실 등에서도 간편하게 깨끗한 물을 마실 수 있도록 개발된 것이 정수기이다. 일반적으로 정수기는 물속에 함유되어 있는 이물질 등을 걸러줌으로써 보다 깨끗한 음용수를 마실 수 있도록 해준다.The water purifier was developed so that you can easily drink clean water at home or office. In general, the water purifier filters out foreign substances in the water to make drinking drinking water cleaner.

근래 들어 정수기의 수요는 날로 증가하고 있는데, 그 원인으로는 과밀화된 인구, 산업의 고도성장, 도시지역의 확대 및 토지이용의 남용 등에 따라 각종 오수를 받아들이는 지표수의 오염도가 심화됨으로써 발생되는 수돗물에 대한 불신에서 기인된 것으로 파악된다.In recent years, the demand for water purifiers is increasing day by day due to the increased pollution of surface water that receives various sewage due to overcrowded population, high industrial growth, expansion of urban areas, and abuse of land use. It is believed that it is caused by distrust of the people.

즉, 상수원으로 이용되고 있는 지표수에 산업폐수, 생활오수 및 축산폐수 등의 오염물질이 유입됨으로써 그 오염도가 날이 갈수록 심화되어 음용수로써 부적당한 지경에 이르고 있다. 이러한 이유로 정수기의 수요는 날로 증가하고 있으며 이의 개량에 많은 연구와 노력을 기울이고 있다.In other words, the inflow of pollutants such as industrial wastewater, domestic sewage, and livestock wastewater into the surface water used as a water supply source is becoming more and more contaminated with drinking water. For this reason, the demand for water purifiers is increasing day by day, and much research and efforts are being made to improve them.

한편, 냉온수기는 정수기가 갖는 정수기능보다는 생수를 냉각하거나 가열하여 간편하게 냉수나 온수를 마실 수 있도록 사용되는 것으로, 정수기와 더불어 근래에 많이 이용되고 있다. On the other hand, cold and hot water is to be used to drink cold water or hot water simply by cooling or heating the bottled water rather than the water purifying function has a water purifier, has been used in recent years with a water purifier.

종래에 정수기나 냉온수기에서 저수통에 저수된 물을 냉각시키거나 가열시키기 위한 냉매파이프 또는 발열히터 파이프를 저수통에 고정하기 위한 냉매·발열히터 파이프 고정구조가 도 1에 도시되어 있다.In the related art, a refrigerant / heating heater pipe fixing structure for fixing a refrigerant pipe or a heating heater pipe to a reservoir to cool or heat water stored in a reservoir in a water purifier or a cold / hot water heater is shown in FIG. 1.

종래 냉매·발열히터 파이프 고정구조에 따르면, 직경이 다른 두 파이프(100)(200)를 서로 연결한 후, 직경이 큰 파이프(100)의 외측에 중공의 고정플랜지(300)를 끼우고, 고정플랜지(300)에 너트(400)를 체결함으로써, 두 파이프(100)(200)가 저수통(500)에 고정되도록 이루어진다. 고정플랜지(300)에는 기밀유지를 위한 패킹부재(600)가 끼워진다.According to the conventional refrigerant / heating heater pipe fixing structure, after connecting two pipes 100 and 200 having different diameters to each other, the hollow fixing flange 300 is fitted to the outside of the large pipe 100 and fixed. By fastening the nut 400 to the flange 300, the two pipes 100 and 200 are fixed to the reservoir 500. The fixing flange 300 is fitted with a packing member 600 for airtightness.

이러한 구성을 갖는 종래 냉매·발열히터 파이프 고정구조에 의하면 직경이 작은 파이프(200)는 직경이 큰 파이프(100)에 삽입된 후 용접에 의해 직경이 큰 파이프(100)와 접합되며, 이는 정수기나 냉온수기에 있어서 몇 가지 문제점을 유발시킨다.According to the conventional refrigerant / heating heater pipe fixing structure having such a configuration, the pipe 200 having a small diameter is inserted into the pipe 100 having a large diameter and then joined with the pipe 100 having a large diameter by welding. It causes some problems in cold and hot water.

첫째, 시간이 경과함에 따라 용접부위(W)가 부식될 염려가 크며, 용접부위(W)가 부식되면 냉매·발열히터 파이프를 구성하는 두 파이프(100)(200)의 연결상태가 양호하지 못하게 되어 두 파이프(100)(200)를 따라 흐르는 냉매 또는 발열유체가 누출될 염려가 커진다. 이처럼 냉매 또는 발열유체가 누출되면 물의 냉각 또는 발열효율이 떨어지게 된다.First, there is a high risk of corrosion of the welding portion (W) as time passes, and if the welding portion (W) is corroded, the connection state of the two pipes (100, 200) constituting the refrigerant / heating heater pipe is poor. Therefore, there is a high risk of leakage of the refrigerant or the heating fluid flowing along the two pipes 100 and 200. As such, when the refrigerant or the heating fluid leaks, the cooling or heating efficiency of the water decreases.

둘째, 용접부위(W) 부식시 발생되는 산화물로 인해 저수통(500) 내부 또는 외부가 오염되어, 수질에 나쁜 영향을 미칠 수 있다.Second, the oxide generated during corrosion of the welding portion (W) is contaminated inside or outside the reservoir 500, which may adversely affect the water quality.

본원발명의 목적은 전술한 바와 같은 종래의 문제점을 해소하기 위하여 안출된 것으로, 용접에 의하지 않고도 냉매 또는 발열유체가 흐르는 두 파이프를 저수통의 소정위치에 안정적으로 고정할 수 있고, 두 파이프의 연결부로부터 냉매 또는 발열유체가 누출되는 것을 방지할 수 있는 냉매·발열히터 파이프 고정구조를 제공하는데 있다.An object of the present invention is to solve the conventional problems as described above, it is possible to stably fix the two pipes through which the refrigerant or heating fluid flows to a predetermined position of the reservoir without welding, the connection portion of the two pipes The present invention provides a refrigerant / heating heater pipe fixing structure capable of preventing leakage of refrigerant or heat generating fluid from the air.

압착부재는, 제1,2 냉매·발열히터 파이프의 외측에 끼워진 상태로 제1,2연결부재에 형성된 파이프 관통홀에 끼워져, 제1,2연결부재 내외의 기밀을 유지시키는 기밀링; 및 제1,2 냉매·발열히터 파이프의 외측에 끼워져 가압부재의 단부에 의해 가압되면서 제1,2 냉매·발열히터 파이프의 외측에 가압되고, 기밀링과 밀착되는 가압링;을 포함하여, 가압링을 이용해 제1,2 냉매·발열히터 파이프를 저수통에 견고히 고정시키고, 기밀링을 이용해 제1,2 냉매·발열히터 파이프의 연결부에서 냉매 또는 발열유체가 누출되는 경우 냉매 또는 발열유체가 제1,2연결부재의 외부로 누출되는 것을 방지한다.The crimping member may include: an airtight ring inserted into a pipe through hole formed in the first and second connection members while being fitted outside the first and second refrigerant / heating heater pipes to maintain the airtight inside and outside the first and second connection members; And a pressurizing ring fitted to the outside of the first and second coolant / heating heater pipes and pressurized by the end of the pressurizing member and pressed to the outside of the first and second coolant / heating heater pipes and in close contact with the hermetic ring. The first and second refrigerant / heating heater pipes are firmly fixed to the reservoir using a ring, and when the refrigerant or the heat generating fluid leaks from the connection portion of the first and second refrigerant / heating heater pipes using the airtight ring, the refrigerant or the heating fluid is removed. Prevent leakage to the outside of 1,2 connecting members.

가압링은 일면이 원추형으로 형성되어 가압부재의 양단부에 각각 삽입되고, 가압부재의 양단부 내측은 가압링의 원추형 경사면에 대응되게 테이퍼져, 가압부재의 단부가 가압링과 밀착되면서 가압할 때 가압링은 중심방향으로 가압된다.One side of the pressure ring is formed in a conical shape and inserted into both ends of the pressing member, and both ends of the pressing member are tapered to correspond to the conical inclined surface of the pressing ring. Is pressed in the center direction.
