Description

(PIPE FIXING STRUCTURE FOR WATER PURIFIER) [0001] The present invention relates to a refrigerant /

The present invention relates to a structure for fixing a coolant / heater pipe, and more particularly, to a structure for fixing a coolant / heating heater pipe which is eco-friendly because there is no fear of contamination of water in a low water bottle, The present invention relates to an exothermic heater pipe fixing structure.

Everyone wants to live long, and the desire to live a healthy life can be seen in the interest of clean water. Recently, tap water disinfected with chlorine is mainly used for washing dishes, washing and cleaning, and bottled water and mineral water are widely used for drinking water.

There is an economical burden because bottled water or mineral water must be purchased from a food or beverage company and purchased from a mart or the like, and it is inconvenient to visit the mart for purchasing.

So it was developed to be able to drink clean water easily at home or office. In general, a water purifier filters out foreign substances contained in water, thereby allowing a cleaner drinking water to be consumed.

Recently, demand for water purifiers has been increasing day by day. The reason for this is believed to be caused by distrust of tap water caused by deepened pollution of surface water that receives various sewage due to overcrowded population, high growth of industry, expansion of urban area and abuse of land use.

In other words, pollutants such as industrial wastewater, domestic sewage, and livestock wastewater are introduced into the surface water used as a water source, and the degree of contamination is getting worse and becoming unsuitable as drinking water. For this reason, demand for water purifiers is increasing day by day, and much research and efforts are being made to improve them.

On the other hand, a cold / hot water machine is used to cool cold water or simply heat cold water to drink cold water or hot water rather than a water purifying function of a water purifier.

1 shows a conventional refrigerant / heating heater pipe fixing structure for fixing a refrigerant pipe or a heating heater pipe for cooling or heating water stored in a water bottle in a water purifier or a cold / hot water heater to a low water bottle.

According to the conventional refrigerant / heater pipe fixing structure, after the two pipes 100 and 200 having different diameters are connected to each other, a hollow flange 300 is fitted to the outside of the large diameter pipe 100, 300 to secure the two pipes 100, 200 to the low-water cistern 500. The flange 300 is fitted with a packing member 600 for hermetic sealing. A sealant 700 for airtightness is inserted between the flange 300 and the pipe 100 having a large diameter in the reservoir 500. As the sealing material 700, a material such as ordinary silicone resin or rubber may be used.

According to the conventional structure for fixing a coolant / heater pipe having such a structure, silicone or rubber can not be completely adhered to plastic or metal, There is concern that it may leak out. In addition, if the sealant is used for a long period of time, the sealant made of silicone or rubber may corrode and contact the water, thereby contaminating the water.

In addition, according to the conventional refrigerant / heater pipe fixing structure, two pipes formed of different materials are connected by welding, so that the corrosion of the transfer pipe during welding causes contamination of the internal environment of the water purifier or the cold / hot water heater, Water may contaminate.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a method of connecting two pipes without welding, The present invention is to provide a refrigerant / heater pipe fixing structure that is environmentally friendly and can improve airtightness by minimizing the use of a material that can cause contamination in a portion where the heater is installed.

According to the present invention, there is provided a refrigerant / heater pipe fixing structure having improved airtightness and improved airtightness, comprising: a pair of pipes in which a coolant or exothermic fluid flows therein and one end thereof is inserted and connected to the other end; A locking ring wrapped around the connecting portion of the two pipes to firmly connect the two pipes and maintain the airtightness of the connecting portion; And a flange fixed through the one surface of the reservoir and having a connection portion of the two pipes penetrating the interior thereof and being firmly fixed.

A rotation preventing protrusion for preventing the rotation of the locking ring against the flange is formed on the inner surface of the flange or on the outer side surface of the locking ring. The rotation preventing protrusion is inserted into the outer surface of the locking ring or the inner surface of the flange, As shown in Fig.

The rotation preventing protrusion and the rotation preventing groove are formed long in the longitudinal direction of the pipe passing through the flange.

The locking ring is constrained to the inside of the flange to be firmly fixed to the inside of the flange, and the airtightness between the locking ring and the flange is maintained due to the interference fit.

According to the present invention, there is provided a refrigerant / heater pipe fixing structure that is environmentally friendly and improved in airtightness, further comprising a sealing member that injects a liquid sealing solution from the outside of the low water tube into the inside of the flange and then hardens to further ensure airtightness between the flange and the pipe do.

According to the present invention, there is provided a refrigerant / heater pipe fixing structure which is environmentally friendly and improved in airtightness, further includes a sealing member which is closely fitted to the inner surface of the flange so as to be fitted to the outside of the pipe outside the low- do.

The flange is integrally injection-molded on the outside of the connecting portion of the two pipes.

According to the present invention, there are the following effects according to the refrigerant / heat generating heater pipe fixing structure which is environmentally friendly and improved in airtightness.

First, since the two pipes through which coolant or exothermic fluid flows are fixedly connected to each other by using a locking ring without depending on welding, there is no possibility of corrosion of the transfer car generated in welding, so that water in the low water bottle is not contaminated.

Secondly, since the locking ring for compressing and securing the two pipes and for maintaining the airtightness between the two pipes is forced into the flange or the flange is integrally injection-molded at the connecting portion of the locking ring and the two pipes, There is no need to provide a sealing member such as silicone resin or rubber between the flange and the pipe, so that there is no fear that the airtight member will corrode and contaminate the water as in the prior art.

Third, the two pipes are firmly fixed by the locking ring, the airtightness between the two pipes is maintained, the locking ring is firmly engaged with the flange and the airtightness is maintained between the flange and the flange, The airtightness at the fixing portion is increased when the fixing is performed.
