본 고안은 제상수 배수관 하단부에 형상기억합금으로 성형한 스프링에 의해 개폐되는 밸브를 착설하여 제상시에만 밸브가 열려 제상수가 배출되도록 한 냉장고의 제상수 배수장치에 대한 것이다.The present invention relates to a defrosting water drainage device of a refrigerator in which a valve is opened and closed by a spring formed of a shape memory alloy at a lower portion of a defrosting water drain pipe so that the defrosting water is discharged by opening the valve only during defrosting.
종래의 냉장고는 제4도에서 보는 바와같이 증발기 표면에 누적되는 성예를 제거하기 위한 제상작동에 따라 발생된 제상수를 배수관(9)을 통해 압축기(10) 상측에 착설한 증발접시(11)위로 흘러 내리게 하여 압축기(10)에서 발생되는 고열로 증발되도록 하였다.In the conventional refrigerator, as shown in FIG. 4, the defrost water generated by the defrosting operation to remove the accumulations on the surface of the evaporator is placed on the evaporation plate 11 installed above the compressor 10 through the drain pipe 9. It was allowed to flow down to evaporate to the high temperature generated in the compressor (10).
그러나 이러한 방법으로 제상수를 배수할 경우 제상작동을 하지 않을 때에는 증발기에서 발생되는 냉기가 배수관을 통해 외부로 누출되어 냉장고내의 저온을 유지하기 위한 냉각 효율이 저하되었음은 물론 제상수가 증발접시에 흘러내려 압축기의 고온에 의해 증발되는 과전에서는 외부의 더운공기와 증발되는 제상수에 의한 고온의 습기가 함유된 뜨거운 열원이 배수관을 통해 증발기 축으로 유입되므로 증발기에 성에가 더욱 많이 발생되는 등의 폐단이 있었다.However, when the defrosting water is drained in this way, when the defrosting operation is not performed, the cold air generated from the evaporator leaks out through the drain pipe and the cooling efficiency for maintaining the low temperature in the refrigerator is deteriorated. In the overheating evaporated by the high temperature of the compressor, the hot heat source containing hot moisture from the outside hot air and the defrosting water evaporated flows into the evaporator shaft through the drain pipe, so more frost is generated in the evaporator. there was.
본 고안은 이와같은 점들을 해결하기 위해, 배수관의 하단부에 밸브를 착설하고, 이 밸브를 개폐하는 개폐변을 온도에 따라 강성이 변화하여 수측 또는 팽창하는 특성을 가진 형상기억합금으로 성형한 스프링에 의해 개폐작동이 이루어지도록 하여 제상작동시에만 개폐변이 열려 제상수가 배출되고 냉각작동시에는 밸브가 닫혀 외부의 더운 열기가 증발기측으로 유입되지 않도록 고안한 것으로 첨부도면에 의거 상술하면 다음과 같다.In order to solve these problems, the present invention installs a valve at the lower end of the drain pipe, and opens and closes the opening / closing valve to a spring formed of a shape memory alloy having a characteristic of changing the water stiffness or expanding according to temperature. By the opening and closing operation to open and close the opening and closing valve only during the defrosting operation defrost water is discharged and the cooling operation is designed to prevent the hot air from flowing into the evaporator side closed as described above according to the accompanying drawings.
배수관(1)의 하단에 고정간(3)이 중앙을 가로지르게 형성된 연결관(2)을 결합하고, 이 연결관(2)의 하단에는 고정간(3')이 하부에 중앙을 가로지르게 형성된 밸브(4)를 결합하여 결착구(5)(5')로 냉장고 캐비네트(6)에 결착토록 하고 개폐변(7)을 상부는 형상기억합금으로 성형한 스프링(8)으로 고정간(3)에 걸고, 하부는 통상의 스프링(8')으로 고정간(3')에 걸어, 연결관(2)과 밸브(4) 사이에 개재되도록 하여서 된 것이다.Coupling tube (2) formed at the lower end of the drain pipe (1) is formed so as to cross the center, and the fixing tube (3 ') is formed at the lower end of the connecting tube (2) across the center The valves 4 are coupled to each other so as to be fastened to the refrigerator cabinet 6 by the fasteners 5 and 5 ', and the opening and closing sides 7 are fixed by the spring 8 formed by the shape memory alloy. ), The lower part is connected to the fixed section 3 'by the usual spring 8', and is interposed between the connecting pipe 2 and the valve 4. As shown in FIG.
이와같이 된 본 고안은 일정온도 이상으로 온도가 상승하면 강성이 발휘되어 원래의 형상, 즉 압축스프링의 수축된 형상으로 복귀되고, 온도가 일정온도 이하로 떨어지면 강성을 잃고 축 늘어지게 되는 특성을 갖는 형상기억합금으로 성형한 스프링(8)으로 개폐변(7)의 상부를 고정간(3)에 걸어 놓았기 때문에 성예를 히이터로 녹이는 제상작동을 하지 않을 때에는 형상기억합금으로 된 스프링(8)은 형상기억합금이 원래의 형상으로 복귀되는 적정온도 이하가 되어 강성을 잃고 축 늘어지는 상태가 되므로 이 상태에서는 하부의 스프링(8')의 수축력이 상기 스프링(8)의 수축력 보다 강하게 되어 개폐변(7)은 제1도와 같이 하측으로 당겨지게 되고, 이에따라 제상수 유출밸브(4)가 열리지 않고 막힌 상태를 유지하게 되므로 외부의 열기가 배수관(1) 측으로 유입되지 않게 된다.The present invention has a characteristic that the rigidity is exhibited when the temperature rises above a certain temperature to return to its original shape, that is, the contracted shape of the compression spring, and loses its rigidity and sags when the temperature falls below a certain temperature. Since the upper part of the opening / closing edge 7 is hanged on the fixed section 3 by the spring 8 formed of the memory alloy, the spring 8 made of the shape memory alloy is shaped when the defrosting operation of melting the sacred body with the heater is not performed. In this state, the contraction force of the lower spring 8 'becomes stronger than the contraction force of the spring 8, so that the memory alloy becomes below a proper temperature for returning to its original shape and loses rigidity. ) Is pulled downward as shown in FIG. 1 and accordingly, the defrost water outlet valve 4 is kept open and blocked, so that external heat flows to the drain pipe 1 side. It is no longer.
한편, 히이터의 작동으로 성에를 녹이는 제상작동시에는 증발기 표면에 누적된 성애가 녹아서 되는 고온(35-40℃)의 제상수가 배수관(1)을 따라 흘러내려 개폐변(7)위에 고이게되고, 이 고온의 제상수는 형상기억합금으로 된 스프링(8)을 가열시켜 형상기억합금이 원래의 형상으로 복귀되는 적정온도 보다 높아지게 되므로, 인장스프링(8)은 형상기억원리에 따라 압축스프링의 수축된 형상으로 복귀되는데, 이때 상기 스프링(8)이 수축되는 수축력은 하부스프링(8')의 수축력과 개폐변(7)의 하중을 합한 힘보다 강하게 되기때문에 개폐변(7)은 제2도와 같이 상승되어 밸브(4)가 열리게 되고 제상수는 밸브(4)를 통과하여 증발접시위로 흘러내리게 된다.On the other hand, during the defrosting operation that melts the frost by the operation of the heater, defrost water of high temperature (35-40 ° C.) in which defrost accumulated on the surface of the evaporator is melted flows down the drain pipe 1 and collects on the open / close valve 7. Since the high temperature defrosting water heats the spring 8 made of the shape memory alloy and becomes higher than an appropriate temperature at which the shape memory alloy is returned to its original shape, the tension spring 8 is contracted of the compression spring according to the shape memory. When the spring 8 contracts, the contracting force of the spring 8 becomes larger than the sum of the contracting force of the lower spring 8 ′ and the load of the opening and closing edge 7, so that the opening and closing edge 7 rises as shown in FIG. 2. As a result, the valve 4 is opened and the defrost water flows down the evaporation plate through the valve 4.
이렇게 작동되어 성에가 완전제거되어 제상수가 다 흘러 내리고 또한, 상기와 같이 제상작동이 완료되고 제상수가 밸브(4)를 통해 외부로 완전히 유출되고 나면, 형상기억 합금으로 된 스프링(8)이 다시 냉각되고, 이에따라 상기 스프링(8)은 형상기억 작용이 상실되어 축 늘어지게 되므로 개폐변(7)은 다시 인장스프링(8')의 수축력에 의해 하향되어 제1도와 같이 밸브(4)를 폐쇄시켜 주게되는 것이다.In this way, the frost is completely removed, the defrost water flows down, and after the defrosting operation is completed as described above and the defrost water is completely flowed out through the valve 4, the spring 8 of the shape memory alloy is released. It cools again, and accordingly, the spring 8 loses its shape memory action and becomes limp. Therefore, the opening / closing edge 7 is lowered again by the contracting force of the tension spring 8 'to close the valve 4 as shown in FIG. I will let you.
이와같이 작동되는 본 고안은 형상기억합금의 특성을 이용하여 개폐변을 제상작동시에만 상승시켜 제상수를 배출시키고 정상작동시에는 밸브를 막아주도록 하므로 외부의 열기가 배수관을 통해 상승되어 냉각효율을 저하시키게 됨에 따라 모든 문제점을 간단히 해결한 매우 유용한 고안이다.The present invention, which operates in this way, uses the characteristics of the shape memory alloy to raise and lower the valve side only during defrosting operation to discharge defrost water and to block the valve in normal operation. This is a very useful design that simply solves all the problems.
