상기와 같은 구성으로 된 본 고안의 일 실시예를 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention having the above configuration will be described in detail.
먼저 냉장고가 구동되면 고내온도센서(30)를 통해 고내가 적정 온도에 도달하였는가를 판단하게 된다(101). 즉, 고내온도센서(30)는 고내의 현재 온도를 감지하여 마이컴(10)에 인가하고 상기 마이컴(10)은 이 입력을 기준온도와 비교 판단하여 고내가 적정 온도인가를 판별하게 된다.First, when the refrigerator is driven, it is determined whether the inside of the refrigerator reaches a proper temperature through the inside temperature sensor 30 (101). That is, the internal temperature sensor 30 senses the current temperature in the interior of the refrigerator and applies it to the microcomputer 10, and the microcomputer 10 determines whether the interior of the refrigerator is at an appropriate temperature by comparing the input with a reference temperature.
상기 고내온도가 적정 온도일 경우에는 내부도어차단 단계(102)가 수행되어 마이컴(10)은 내부도어구동수단(50)으로 제어신호를 출력하고 이를 입력받은 내부도어구동수단(50)은 내부도어(60)를 구동시켜 상기 내부도어(60)를 차단하게 된다.When the internal temperature is a proper temperature, the internal door blocking step 102 is performed so that the microcomputer 10 outputs a control signal to the internal door driving means 50 and the internal door driving means 50 receives the internal door. The inner door 60 is cut off by driving 60.
한편, 상기 고내온도가 적정 온도가 아닐 경우에는 내부도어개방 단계(103)가 수행되어 마이컴(10)은 내부도어구동수단(50)으로 제어신호를 출력하고 이를 입력받은 내부도어구동수단(50)은 내부도어(60)를 구동시켜 상기 내부도어(60)를 개방시키게 된다.On the other hand, when the internal temperature is not the proper temperature, the internal door opening step 103 is performed so that the microcomputer 10 outputs a control signal to the internal door driving means 50 and receives the internal door driving means 50. The inner door 60 is driven to open the inner door 60.
따라서, 고내가 적정온도가 아닐 경우 내부도어(60)가 개방되어 도어포켓(21) 쪽까지 냉기가 순환됨으로서 냉장고 내부 전체가 냉각되도록 한다. 또한, 고내가 적정 온도일 경우에는 내부도어(60)를 차단하여 이때, 냉장고도어(2)를 열어도 냉기가 외부로 유출되지 않도록 한다.Therefore, when the inside of the refrigerator is not at the proper temperature, the inner door 60 is opened to cool the entire inside of the refrigerator by circulating cold air to the side of the door pocket 21. In addition, when the inside of the refrigerator is at an appropriate temperature, the internal door 60 is blocked so that cold air does not leak to the outside even when the refrigerator door 2 is opened.
이후, 도어스위치(20)가 온 인가를 감지하여 상기 마이컴(10)에 인가함으로서 냉장고도어(2)의 열림 또는 닫힘 상태를 판단하게 된다(104).Thereafter, the door switch 20 senses the on-apply and applies it to the microcomputer 10 to determine the open or closed state of the refrigerator door 2 (104).
상기 판단에 의하여 도어스위치(20)가 온 일 경우 마이컴(10)은 냉장고도어(2)의 열림 상태를 인지하고 고내등(4)을 온 시킴과 동시에 내부도어구동수단(50)을 구동시켜 내부도어(60)를 차단함으로서 고내의 냉기가 외부로 유출되지 못함과 아울러 외부의 더운 공기도 내부로 유입되지 못하도록 한다.When the door switch 20 is turned on by the determination, the microcomputer 10 recognizes the open state of the refrigerator door 2, turns on the interior light 4, and simultaneously drives the inner door driving means 50 to operate the inner door. By blocking (60), cold air in the refrigerator is prevented from leaking to the outside and hot air from the outside is not allowed to flow into the inside.
한편 도어스위치(20)가 온이 아닐 경우, 즉 오프일 경우 마이컴(10)은 냉장고도어(2)의 닫힘 상태를 인지하고 고내등(40)을 오프시킴과 동시에 내부도어구동수단(50)을 구동시켜 내부도어(60)를 개방하게 된다.On the other hand, when the door switch 20 is not on, that is, off, the microcomputer 10 recognizes the closed state of the refrigerator door 2, turns off the interior lamp 40, and simultaneously drives the inner door driving means 50. The inner door 60 is opened.
따라서, 고내의 냉기가 냉장고 도어포켓(21) 쪽까지 고루 순환되어 적정 온도를 유지하게 된다.Therefore, the cold air in the refrigerator is circulated evenly to the refrigerator door pocket 21 to maintain the proper temperature.
이상에서와 같이 본 고안에 따른 냉장고 냉기유출 방지장치에 의하면, 냉장고 내부에 별도의 도어를 설치하여 자동으로 개방되거나 차단되게 함으로서, 냉장고의 도어를 여닫을 때 냉장고 내부의 냉기가 외부로 유출되지 않도록 하여 냉장고 효율을 극대화시키는 효과가 있다.As described above, according to the refrigerator cold air outflow prevention device according to the present invention, by installing a separate door inside the refrigerator to automatically open or cut off, so that the cold air inside the refrigerator does not leak to the outside when opening the door of the refrigerator It is effective to maximize the efficiency of the refrigerator.
