정수라인의 튜브 접속구조{tubing conjunction structure for water purifying path}Tubing conjunction structure for water purifying path

본 발명은 정수기나 냉장고의 정수라인에서 정수필터의 인렛이나 아웃렛 또는 기타 부속을 연결하기 위한 튜브 접속구조에 관한 것으로, 단수부품만을 이용하여 간편하게 체결할 수 있으면서도 긴밀하게 실링이 이루어질 수 있도록 한 것이다.The present invention relates to a tube connection structure for connecting an inlet or an outlet or other parts of a water filter in a water purification line of a water purifier or a refrigerator, so that the sealing can be made tightly while being easily tightened using only a single component.

일반적으로 디스펜서가 장착된 냉장고나 정수기는 정수라인의 유로 상에 다양한 종류의 필터가 용도에 따라 연결 설치되어 물이 필터를 경유하면서 물리적, 화학적인 과정을 거쳐서 정수할 수 있도록 되는 것이고, 또한 이러한 유로 상에는 워터밸브나 유량조절밸브 등이 장착되어 유량의 공급을 제어할 수 있도록 되는 것으로, 이러한 필터 또는 기타장치에는 각각 물이 주입되는 인렛과 물이 배출되는 아웃렛이 형성되어 각각의 인렛과 아웃렛에 튜브를 연결함으로써 유로가 형성되도록 하는 것이다.In general, a refrigerator or a water purifier equipped with a dispenser is provided with various types of filters connected to a water purifying line according to the use so that water can be purified through a physical and chemical process while passing through the filter. The water valve or flow control valve is installed on the upper part to control the supply of the flow rate. Such a filter or other device is provided with an inlet through which water is injected and an outlet through which the water is discharged. By connecting the to form a flow path.

따라서 냉장고나 정수기 내에는 여러 지점에서 튜브의 접속이 이루어지는 것으로, 이러한 튜브가 접속된 지점이 많아질수록 누수 지점이 많아진다는 의미이기 때문에 냉장고나 정수기를 사용중 고장이 발생하지 않도록 하기 위해서는 이러한 튜브의 접속구조가 긴밀히 이루어지도록 하는 것이 무엇보다 중요한 것이다.Therefore, the tubes are connected at various points in the refrigerator or the water purifier, and the more the points connected to these tubes, the more the leak points. The most important thing is to ensure the structure is tight.

따라서 튜브의 긴밀한 접속을 위하여 인렛과 아웃렛에 형성된 피팅부에 별도의 캡을 나사 조임방식으로 조여 결합하거나, 또는 별도의 결합구를 형성하여 조립이 이루어지도록 하는데, 이러한 것의 문제가 그 조립구조가 복잡해지게 될 뿐만 아니라, 조립을 위한 부품의 수가 많아지게 되므로 제조단가가 상승하여 동업종 분야에서 가격경쟁력이 떨어지는 문제가 있으며, 또한 부품의 증가로 인한 필터 조립의 작업성이 저하되는 문제가 있는 것이다.Therefore, in order to closely connect the tube, a separate cap is coupled to the fitting formed in the inlet and the outlet by screwing, or an assembly is formed by forming a separate coupling hole. In addition to increasing the number of parts for assembling, there is a problem that the manufacturing cost is increased to reduce the price competitiveness in the field of the same industry, and there is also a problem that the workability of the filter assembly due to the increase of parts is reduced.

특히 이러한 필터나 워터밸브와 같은 장치의 하우징은 재질이 합성수지로 이루어지는 반면에, 조립구의 재질은 연결호스를 긴밀하게 연결하여 누수를 방지하기 위해서 대부분 필터 헤드에 금속의 니플이나 별도의 부속을 조립하여 연결호스를 접속하는 방법이 주로 사용되는데, 이 경우 합성수지로 이루어진 필터 본체에 금속의 부속을 결합하기 위해서는 부품의 정밀한 가공이 필요하며, 서로 다른 재질의 체결에 의하여 누수포인트가 발생할 우려가 있는 것이다.In particular, the housing of such a filter or a water valve is made of synthetic resin, whereas the material of the assembly is made by assembling a metal nipple or a separate part in the filter head in order to closely connect the connection hose to prevent leakage. The method of connecting the connection hose is mainly used. In this case, in order to join the metal parts to the filter body made of synthetic resin, it is necessary to precisely process the parts, and leak points may occur due to the fastening of different materials.

그리고 이러한 튜브를 합성수지로 형성할 경우 물을 공급하거나 차단할 때 발생되는 수압이 그 연결부에 반복적으로 걸리게 되므로 장기간 사용시 튜브 연결부위가 손상되거나 파손되면서 누수가 발생하게 되는 문제가 있는 것이다.When the tube is formed of synthetic resin, the water pressure generated when supplying or blocking water is repeatedly applied to the connection part, so that a leak occurs as the tube connection part is damaged or broken during long-term use.

또한 이러한 튜브를 끼워 접속할 때 튜브가 피팅부에 완전하게 끼워져 조립되었는지의 여부를 육안으로 판단할 수 없고, 작업자가 느낌으로 판단할 수밖에 없기 때문에 정확한 판단이 이루어지기가 어려우므로 점검 과정이나 사용 중 불량이 발생되는 경우가 빈번하게 발생하는 것이다.In addition, when such a tube is connected, it is impossible to visually determine whether the tube is completely inserted into the fitting part and assembled, and it is difficult to make an accurate judgment because the operator has no choice but to judge it. This happens frequently.

따라서 누수가 발생치 않게 조립의 불량률을 줄이기 위해서는 튜브와 피팅부를 빡빡하게 끼워서 결합을 하여야 하므로 조립공정에서 작업자가 강한 힘으로 조립해야 하는데, 조립완료 여부를 작업자가 정확하게 판단할 수 없기 때문에 과도한 힘이 들어가게 되고, 이러한 조립작업을 반복 지속적으로 수행하는 작업자의 입장에서는 힘이 과도하게 소모되며 조립공정에서의 작업이 어려워 작업성과 생산성이 떨어지는 문제가 있는 것이다.Therefore, in order to reduce the defective rate of assembly to prevent leakage, the tube and fittings should be tightly coupled so that the worker must assemble with strong force in the assembly process. From the perspective of the worker who continues to perform such assembly work repeatedly, excessive power is consumed and the work in the assembly process is difficult, and workability and productivity are inferior.

따라서 본 발명은 유로상에 장착되는 튜브의 접속구조가 누수포인트를 최소화하면서 기밀성을 높이고, 연결부속의 수를 최소화함으로써 튜브의 접속이 단수부품으로 간단하게 조립할 수 있도록 하고, 또한 이러한 조립의 완료상태를 육안으로 확인할 수 있도록 함으로써 긴밀히 접속이 이루어지도록 한 것이다.Therefore, the present invention improves the airtightness while minimizing the leakage point of the connection structure of the tube mounted on the flow path, so that the connection of the tube can be easily assembled into a single part by minimizing the number of connecting parts. By making it visible to the naked eye, the connection is made tightly.

그리고 이러한 조립구조가 수압에 대한 내구성을 향상시켜 장기간 반복적으로 수압이 걸릴 경우에도 연결부위가 손상되거나 파손되는 것을 방지할 수 있도록 한 것이다.In addition, this assembly structure is to improve the durability against the hydraulic pressure to prevent damage to or damage to the connection even if the hydraulic pressure is repeatedly taken for a long time.

이를 위하여 본 발명은 정수라인의 유로 상에 장착되는 필터나 기타 장치의 인렛과 아웃렛에 형성되는 피팅부의 단부에 튜브연결부를 돌출되게 형성하면서 그 튜브연결부의 외주면에는 튜브걸림부와 캡걸림부를 형성하여 튜브와 체결캡이 강제 끼움으로 조립되도록 하고, 체결캡에는 원통형의 서스를 내장함으로써 피팅부의 보강이 이루어지면서 피팅부의 꺾임을 방지하면서 그 접속구조가 누수포인트를 최소화하면서도 피팅부와 체결캡과 튜브의 자체탄성력에 의하여 실링이 이루어져 누수를 방지할 수 있게 긴밀히 결합되어지도록 하며, 캡의 재질을 투명체로 형성하여 불투명으로 이루어지는 금속 서스에 의하여 튜브의 끼움 조립상태를 육안으로 확인할 수 있도록 한 것이다.To this end, the present invention forms a tube catching portion and a cap catching portion on the outer circumferential surface of the tube connecting portion while protruding the tube connecting portion at the end of the fitting portion formed in the inlet and the outlet of the filter or other device mounted on the flow path of the water purification line. The tube and the fastening cap are assembled by force fitting, and by inserting the cylindrical sus in the fastening cap, the reinforcing part of the fitting is made, preventing the fitting part from being bent, while the connection structure minimizes the leakage point, while the fitting part and the fastening cap and the tube The sealing is made by self-elastic force so that it can be tightly coupled to prevent leakage, and the material of the cap is formed of a transparent body so that the fitting state of the tube can be visually checked by an opaque metal suspension.

또한, 피팅부의 튜브연결부에도 원통형의 금속 서스를 내장하여 피팅부와 캡에 각각 형성된 서스에 의하여 이중 서스 구조로 보강되면서 전단응력을 향상시켜 누수를 방지하면서 튜브의 꺾임을 방지토록 한 것이다.In addition, the tubular connection portion of the fitting is also built in a cylindrical metal sussing is reinforced by a double sus structure by the su respectively formed in the fitting portion and the cap to improve the shear stress to prevent leakage of the tube while preventing leakage.

따라서 본 발명은 냉장고나 정수기의 유로 상에서 필터 또는 기타부품에 튜브를 간단하게 체결할 수 있고, 튜브의 조립완료 여부를 육안으로 직접 확인할 수 있으므로 조립공정에서의 작업성을 높이면서도 부품의 간소화는 물론, 제작단가를 줄여 경제성을 높이면서도 품질을 향상시킬 수 있는 것이다.Therefore, the present invention can simply fasten the tube to the filter or other parts on the flow path of the refrigerator or the water purifier, and can directly check whether the tube is completed, so as to simplify the parts while increasing workability in the assembling process. Therefore, it is possible to improve the quality while increasing the economic efficiency by reducing the manufacturing cost.

또한, 내장된 서스에 의하여 압력에 대한 내구성을 확보하여 냉장고나 정수기를 장기간 사용시에도 유로상에서 연결부위가 파손되는 것을 방지하여 고장나지 않으면서도 누수를 방지할 수 있게 되어 유지보수비용을 절감할 수 있는 것이다.In addition, the built-in susor ensures durability against pressure, and prevents the connection part from being broken on the flow path even after long-term use of the refrigerator or water purifier to prevent water leakage without failure, thereby reducing maintenance costs. will be.

그리고 단수부품으로 체결되는 단순한 조립구조로 인하여 연결부위의 누수포인트를 최대한 줄일 수 있게 되며, 피팅부와 체결캡 및 튜브가 맞닿는 부분이 모두 합성수지로 이루어지므로 체결 및 분해시 부품이 손상되지 않으면서도 서로 간에 자체탄성력에 의하여 상호 지지하는 형태로 접속이 이루어지므로 장기간 사용시에도 누수를 방지하면서도 접속부위의 기밀성을 유지할 수 있는 것이다.In addition, the leak point of the connecting part can be reduced as much as possible due to the simple assembly structure that is fastened by the singular parts. Since the connection is made in the form of mutual support by the self-elastic force, it is possible to maintain the airtightness of the connection part while preventing leakage even during long-term use.

이하 첨부도면에 의거 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 도 1 및 도 2에 도시된 바와 같이 냉장고나 정수기의 정수라인 상에서 워터밸브나 필터 등에 형성되는 피팅부(10)에 튜브(20)를 연결하기 위한 구조로서, 피팅부(10)에 튜브연결부(11)를 형성하고, 튜브연결부(11)의 외주면에는 튜브걸림부(12)와 캡걸림부(13)를 형성하여 튜브(20)와 체결캡(30)이 강제 끼움으로 조립되도록 하며, 그 체결캡(30)에는 원통형의 금속 서스(34)를 내장하여 압력에 의한 체결캡(30)의 형태변형을 방지하면서 튜브(20)와 체결캡(30)의 전단응력이 향상되고 튜브(20)의 꺾임이 방지되도록 한 것이다.1 and 2 as a structure for connecting the tube 20 to the fitting portion 10 formed in the water valve or filter on the water purification line of the refrigerator or water purifier, as shown in Figure 1 and 2, The tube connecting portion 11 is formed, and the tube catching portion 12 and the cap catching portion 13 are formed on the outer circumferential surface of the tube connecting portion 11 so that the tube 20 and the fastening cap 30 are assembled by force fitting. In the fastening cap 30, a cylindrical metal susche 34 is incorporated to prevent the deformation of the fastening cap 30 due to pressure while the shear stress of the tube 20 and the fastening cap 30 is improved, and the tube ( It is to prevent the bending of 20).

즉, 상기 체결캡(30)은 원통형의 금속 서스(34)를 인서트 성형으로 내장하면 피팅부(10)에 체결캡(30)이 강제 끼움으로 결합될 때 체결캡(30)에 높은 압력이 걸려도 보강이 가능토록 되는 것으로, 이러한 결합구조에서는 튜브(20)가 끼워져 걸림되는 부분, 즉 피팅부(10)의 튜브걸림부(12)에서 튜브(20)가 미세하게 돌출되므로 이 부분에서 가장 압력이 많이 발생하게 되는데, 이러한 튜브걸림부(12)가 위치한 지점의 외측을 가압하도록 서스(34)를 체결캡(30)에 내장함으로써 체결캡(30) 전체가 미세하게 벌어짐되는 것을 방지하면서 튜브(20)와 체결캡(30)의 전단응력을 더욱 높여 밀폐력을 향상할 수 있게 되는 것이고, 이러한 서스(34)에 의하여 보강되어져 체결캡(30)이 파손되거나 손상되는 것을 방지할 수 있게 되는 것이다.That is, when the fastening cap 30 is embedded with a cylindrical metal suss 34 by insert molding, even if a high pressure is applied to the fastening cap 30 when the fastening cap 30 is forcibly fitted to the fitting part 10. In this coupling structure, the tube 20 is inserted into and engaged in the coupling structure, that is, the tube 20 protrudes finely from the tube catching portion 12 of the fitting portion 10. It is generated a lot, by embedding the sus 34 in the fastening cap 30 to press the outside of the point where the tube catching part 12 is located, the fastening cap 30 is prevented from being minutely opened while the tube 20 It is to be able to improve the sealing force by further increasing the shear stress of the) and the fastening cap 30, it is to be reinforced by such a susu 34 to prevent the fastening cap 30 is damaged or damaged.

이때, 상기 체결캡(30)은 테두리를 따라서 형성된 외벽(31)의 내주면에 후크걸림부(32)를 형성함으로써 피팅부의 캡걸림부(13)에 강제 끼움으로 끼워져 고정되도록 하는 것이고, 이때 그 후크걸림부(32)는 외벽(31)의 내주면 전체에 형성되도록 하거나, 또는 후크걸림부(32)가 부분적으로 형성되면서도 내주면을 따라서 복수로 형성하여 강제 끼움이 이루어질 수 있도록 할 수 있는 것이다.At this time, the fastening cap 30 is to be fixed by fitting to the cap catching portion 13 of the fitting part by forming a hook catching portion 32 on the inner circumferential surface of the outer wall 31 formed along the rim, wherein the hook The locking portion 32 may be formed on the entire inner circumferential surface of the outer wall 31, or the hook locking portion 32 may be formed in plural along the inner circumferential surface while being partially formed so that a forced fit may be performed.

이때, 상기 외벽(31)에 복수의 절개부(33)를 형성하면 외벽(31)이 자체탄성력에 의하여 내, 외측으로 탄성작동하게 되는 것이고, 이러한 탄성작동에 의하여 체결캡(30)을 강제 조립하거나 분해할 경우에 용이하게 탈부착을 할 수 있게 되는 것이다.In this case, when the plurality of cutouts 33 are formed on the outer wall 31, the outer wall 31 is elastically operated inward and outward by self-elastic force, and the fastening cap 30 is forcedly assembled by the elastic operation. In case of disassembly or disassembly it will be easy to attach.

또한, 체결캡(30)을 투명체로 이루어지도록 하면 그 안에 내장되어 있는 서스(34)를 외부에서 육안으로 확인할 수 있게 되는 것이고, 따라서 불투명체로 이루어진 금속 서스(34)를 가늠자로 하여 튜브(20)의 끼움 정도를 판단할 수 있게 되는 것이다.In addition, when the fastening cap 30 is made of a transparent body, it is possible to visually check the sus 34 embedded therein from the outside, and thus the tube 20 with the metal sus 34 made of an opaque body as a scale. Will be able to determine the degree of fit.

즉, 체결캡(30)에 내장된 서스(34)의 길이를 형성함에 있어서, 도 5에 도시된 바와 같이 그 서스의 단부를 튜브(20)가 피팅부(10)에 완전히 끼워진 상태에서 튜브(20)의 단부와 일치되도록 형성하면 도 5a와 같이 체결캡을 끼워 조립할 경우에 튜브(20)의 단부가 외부로 노출되어 보이면 체결캡(30)의 조립이 미완료된 상태임을 작업자가 육안으로 확인할 수 있고, 튜브(20)의 단부가 서스(34)에 가려져 보이지 않게 되면 체결캡의 조립이 완료된 상태를 이루게 되므로 서스(34)를 눈금자로 활용하여 체결캡(30)의 조립완료상태를 점검할 수 있게 되는 것이다.That is, in forming the length of the suss 34 embedded in the fastening cap 30, as shown in FIG. 5, the end of the sussing tube 20 in the state where the tube 20 is completely fitted to the fitting portion 10 ( If formed to match the end of 20) when the assembly is fitted with a fastening cap as shown in Figure 5a when the end of the tube 20 is exposed to the outside, the operator can visually confirm that the assembly of the fastening cap 30 is incomplete state In addition, when the end of the tube 20 is hidden by the suss 34, the assembly of the fastening cap is completed, so that the assembly completion state of the fastening cap 30 can be checked by using the sus 34 as a ruler.
