본 고안은 냉장고의 냉각기로부터 닥트를 통해 유도되는 냉매가스가 냉장실 내부로 유입되는 정도에 따라 냉장실 온도 정도가 조절되는 것으로 닥트를 통해 냉장실을 통과하게 되는 냉매유입 경로의 개폐기능을 형상 기억합금의 특성을 이용하여 냉매가스 유입을 제어할 수 있도록 한 형상기억합금을 이용한 냉장고 온도 조절장치에 관한 것이다.The present invention is to control the temperature of the refrigerating chamber according to the degree to which the refrigerant gas induced through the duct from the refrigerator of the refrigerator enters the inside of the refrigerating chamber. It relates to a refrigerator temperature control device using a shape memory alloy to control the refrigerant gas inlet using.

종래의 경우 냉장고에서 냉장실의 냉장온도 조절은 닥트를 통해 유도되는 냉매가스의 냉장실 유입경로를 개폐시키게 되는 냉기 조절판의 동작으로 온도센서를 냉매가 흐르는 모세관에 밀착장착하여 냉매가스 온도를 감지하여 제반 냉매가스 제어에 필요한 기구적 장치를 동작시켜 냉매가스의 냉장실 유입되는 량을 조절하여 냉장실 온도조절을 하게 되었으나 구조적으로 복잡할 뿐 아니라 별도의 온도센서 감지기능에 의해 냉매가스 유입되는 경로를 개폐하게 되어 고장발생이 잦은 결점이 있었다.In the conventional case, the refrigerating temperature control of a refrigerating compartment in a refrigerator is an operation of a cold air control plate that opens and closes a refrigerating chamber inflow path of a refrigerant gas induced through a duct, and attaches a temperature sensor to a capillary through which a refrigerant flows to detect a refrigerant gas temperature. The mechanical device necessary for gas control is operated to control the amount of refrigerant gas inflow to the refrigerator, but the temperature of the refrigerator is controlled. However, it is not only structurally complicated but also opens and closes the path of refrigerant gas inflow by a separate temperature sensor detection function. There were frequent defects.

따라서, 본 고안은 이와 같은 종래의 결점을 해소시키기 위해 냉장실로 유입되는 냉매가스 경로를 개폐기능을 하게되는 기구적 장치중에서 한 부품의 소재를 형상 기억 합금을 채택하여 소재의 특성을 이용하여서 된 것으로 첨부된 도면에 따라 그 구성 및 작용효과를 상세히 설명하면 다음과 같다.Therefore, the present invention was made by utilizing the characteristics of the material by adopting the shape memory alloy of the material of one component of the mechanical device to open and close the refrigerant gas path flowing into the refrigerating chamber to solve such a conventional defect. According to the accompanying drawings, the configuration and operation effects will be described in detail as follows.

냉장실(1)내면에 감지구(5)와 냉기출구(4)가 형성된 케이스(2)를 장착한 것에 있어서, 내측면에 걸림고리(9)와 면상에 안내봉(6)이 형성되고 안치구(12)를 가진 케이스(2)내부에 일단에는 냉기조절판(3)이 부착되고 타단에는 안치구(12)와의 사이에 스프링(10a)이 부착된 탄력봉(11)에 절곡되면서 안내구멍(8)이 형성된 레버(7)를 부착하고 이 레버(7)의 안내구멍(8)을 안내봉(6)에 맞춰 삽입하면서 걸림고리(9)와의 사이에 형상기억합금의 소재로된 스프링(10)을 장착하여 감지구(5)로부터 유입된 냉기에 의해 형상 기억 합금으로된 스프링(10)의 신축 작용으로 탄력봉(11) 단부에 장착된 냉기조절판(3)이 냉기 닥트(13)의 통로를 개폐할 수 있게한 것이다.In the case 2, in which the sensing port 5 and the cold air outlet 4 are formed on the inner surface of the refrigerating chamber 1, the hook ring 9 and the guide rod 6 are formed on the inner surface, Inside the case (2) having a (12), the cold air control plate (3) is attached to one end and the other end is bent to the elastic rod (11) attached with a spring (10a) between the settle (12) guide hole (8) A spring (10) made of a shape memory alloy between the hook ring (9) while attaching a lever (7) formed therein and inserting the guide hole (8) of the lever (7) in accordance with the guide rod (6). The cold air control plate (3) mounted at the end of the elastic rod (11) by the expansion and contraction action of the spring (10) made of a shape memory alloy by the cold air introduced from the detection port (5) to the passage of the cold air duct (13) It can be opened and closed.

이와 같이 구성되어진 본 고안의 작용효과를 상세히 설명하면 다음과 같다.If described in detail the effect of the present invention is configured as follows.

냉장고에 전원이 통전되어 냉각기 구동으로 발생되는 냉기는 닥트(13)를 통해 냉장실온도가 소정의 온도보다 높은 온도인 상태에서는 탄력봉(11) 단부에 장착된 냉기조절판(3)이 형상기억합금으로 된 스프링(10)의 수축에 의해 닥트(13)의 통로가 개방되어 있는 상태가 되므로 닥트(13)를 통해 케이스(2)내부로 유도된 냉기는 케이스의 하향으로 형성된 냉기 출구를 통해 냉장실내부로 냉기를 유도하게 되어 냉각기로부터 발생된 냉기를 냉장실 유도에 따라 냉장실의 온도를 소정의 온도로 낮춰줄 수 있게되며 일단 냉장실 온도가 정상의 냉장온도가 유지되었을 때 냉장실의 냉기는 케이스( 2)에 형성된 감지구(5)를 통과 분포되어 있는 상태로서 감지구(5) 직상부 위치에 레버(7)의 단부와 걸림고리(9)사이 장착된 형상기억 합금을 소재로 제조된 스프링(10)에 낮은 온도가 적용됨에 따라 소재의 특성에 의해 스프링(10)은 팽창되면서 레버(7 )에 팽창력이 작용되어 레버(7)를 밀어주게 되므로 레버(7)의 안내구멍(8)은 안내봉( 6)의 안내를 받으며 후방으로 밀리면서 레버(7) 끝단에 일체로 장착된 탄력봉(11)을 같이 밀어내게되어 탄력봉(11) 단부에 결착된 냉기 조절판(3)은 형상기억합금 소재로의 스프링 (10)과 스프링(10a)의 탄성력을 밀폐력으로 하여 닥트(13)를 통해 케이스(2)내부로 냉기가 유입되는 경로를 차단하게 되므로 냉기의 냉장실 유입을 완전밀폐시키므로서 냉장실 온도를 유지하게 되는 것이며 이때 안치구(12)와 탄력봉(11)단부 사이 장착된 스프링(10a)은 탄력봉(11)의 이동 안내기능과 형상기억합금 소재의 스프링(10) 팽창시 닥트(13)를 통해 유입되는 통로를 밀폐력을 보조하는 기능을 지닌 것이다.The cool air generated by driving the cooler by supplying power to the refrigerator is a cool memory control plate 3 mounted at the end of the resilient rod 11 as a shape memory alloy when the refrigerating chamber temperature is higher than a predetermined temperature through the duct 13. Since the passage of the duct 13 is opened by the contraction of the spring 10, the cold air guided into the case 2 through the duct 13 enters the refrigerating chamber through the cold air outlet formed downward of the case. By inducing cold air, it is possible to lower the temperature of the refrigerating compartment to a predetermined temperature according to the induction of the refrigerating compartment from the refrigerator. Once the refrigerating compartment temperature is maintained at the normal refrigerating temperature, the refrigerating compartment is formed in the case (2). A shape memory alloy mounted between the end of the lever 7 and the hook ring 9 at the position immediately above the sensing port 5 in the state distributed through the sensing port 5 is formed on the spring 10 made of the material. As the temperature is applied, the spring 10 is expanded due to the characteristics of the material, and the expansion force is applied to the lever 7 to push the lever 7, so that the guide hole 8 of the lever 7 is a guide rod 6. While pushing backwards with the guidance of the push rod (11) integrally mounted on the end of the lever (7) together, the cold air control plate (3) bound to the end of the elastic rod (11) is a spring of the shape memory alloy material Since the elastic force of the (10) and the spring (10a) as a sealing force to block the path through which the cold air flows into the case (2) through the duct 13 to maintain the refrigerator compartment temperature while completely closing the inlet of the cold air In this case, the spring 10a mounted between the end fixture 12 and the end of the resilient rod 11 is introduced through the duct 13 during expansion of the spring 10 of the shape memory alloy material and the movement guide function of the resilient rod 11. The passage is to have a function to assist the sealing force.

또한, 냉장실(1)의 온도가 정상의 냉장온도 이상의 온도가 유지될 경우에는 감지구(5)를 통해 냉장실(1) 온도가 형상기억 합금소재의 스프링(10)에 작용됨에 따라 스프링(10)은 수축되면서 레버(7)를 당겨주게되어 닥트(13)를 통해 유입되는 통로를 밀폐시키는 동작과는 정반대의 동작으로 냉기조절판(3)은 냉기 유입통로를 개방하게 되어 냉기출구(4)를 통해 냉장실(1)로 냉기 유입될 수 있게 하게 되어 냉장온도를 적정 유지시키게 되는 전반적인 동작 상태를 지닌 것으로 즉, 이미 전자산업 분야에서 널리 이용되고 있는 형상 기억 합금 소재의 특성을 이용키 위해 채택하여 냉장실 온도 조절에 적용 실시하므로서, 기능의 신뢰성과 단순한 구조로 제품의 품질을 향상시키게 된 것이다.In addition, when the temperature of the refrigerating chamber 1 is maintained at a temperature higher than the normal refrigerating temperature, the refrigerating chamber 1 temperature is acted on the spring 10 of the shape memory alloy material through the detection port 5, and thus the spring 10. Is contracted while pulling the lever (7) to close the passage flowing through the duct 13 in the opposite operation to the cold air control plate (3) to open the cold air inlet passage through the cold air outlet (4) Cold air flows into the refrigerating compartment (1) and has an overall operating state to maintain the refrigerating temperature appropriately, that is, it is adopted to take advantage of the characteristics of the shape memory alloy material that is already widely used in the electronics industry. By applying it to the adjustment, the reliability of the function and the simple structure improve the product quality.
