Description
본 발명은 기계식 냉장고에 관한 것으로, 보다 상세하게는 냉동실 센서를 이용하여 감지한 냉동실의 냉동온도와 압축기의 운전율 변화에 따른 온도상태를 각 단계별로 판단하여 적절하게 축적된 데이터의 냉장실 온도를 외부의 사용자에게 디스플레이 시켜주기 위한 냉장실의 온도표시방법에 관한 것이다.The present invention relates to a mechanical refrigerator, and more particularly, to determine the temperature state according to the change in the freezing temperature of the freezer compartment and the operating rate of the compressor detected by the freezer compartment for each step to determine the externally stored refrigerator temperature of the data. The present invention relates to a temperature display method of a refrigerator compartment for displaying to a user.
일반적으로, 냉장고의 냉동싸이클은 압축기에서 토출된 고온고압의 냉매가스가 응축기를 통과하면서 외부로 열이 방출되어 고압의 액상냉매가 된 후에, 드라이어를 통과하면서 고압의 액상냉매는 불순물과 수분 등이 제거되어 캐필러리튜브를 거치게 되며, 캐필러리튜브를 통과하면서 액상냉매는 증발하기 쉬운 기액 혼합상태로 팽창되어 증발기를 통해 주변의 열을 흡수하여 가스화되는 순환반복에 의해 냉장고에 냉기공급이 이루어 진다.In general, the refrigeration cycle of the refrigerator is a high-pressure liquid refrigerant after the heat is released to the outside as the high-temperature high-pressure refrigerant gas discharged from the compressor passes through the condenser, and the high-pressure liquid refrigerant while passing through the dryer is free of impurities and moisture After being removed, it passes through the capillary tube, and the liquid refrigerant expands to a gas-liquid mixed state that is easily evaporated while passing through the capillary tube. Lose.
도3을 참조하여 종래 냉장고의 제어장치를 개략적으로 살펴보면, 냉동실의 온도를 각지하는 냉동실 센서(31), 냉동실의 온도변화를 마이콤(33)의 입력신호로 변환하는 센서신호 변환수단(32), 압축기(35), 냉장팬(36) 및 제상히터(37)를 구동하기 위한 구동수단(34)을 구비하여 냉장실에 냉기를 공급하게 된다.Referring to FIG. 3 schematically, a control apparatus of a conventional refrigerator includes: a freezer compartment sensor 31 for detecting a temperature of a freezer compartment, a sensor signal converting means 32 for converting a temperature change of a freezer compartment into an input signal of a microcomputer 33; The compressor 35, the refrigerating fan 36 and the drive means 34 for driving the defrost heater 37 is provided to supply cold air to the refrigerating chamber.
그러나, 최근에는 냉장고의 운전시 냉장실내에 과부하가 투입되거나, 냉장실의 도아가 열려 외기가 유입되어 냉장실의 온도가 상승하는 경우, 압축기와 냉장실 팬만을 사용하는 종래의 운전방법보다 냉장실의 전체온도를 정상적인 온도로 신속하게 회복시켜주기 위하여 에어커튼팬을 냉장실에 추가로 설치하여 사용하기도 한다. 이러한 최근의 냉장고에서는 냉장실의 온도를 외부의 사용자에게 알려주기 위한 디스플레이수단이 냉장고의 외측 소정부위에 부착되어 사용자가 직접 확인할 수 있게 하고 있으너, 기계(댐퍼)식 냉장실에 대해서는 적절한 온도표시방법이 없으므로 냉장실의 온도를 외부의 사용자에게 디스플레이하지 못하여 소비자의 불만이 야기되는 문제가 있다.Recently, however, when an overload is introduced into the refrigerating compartment during operation of the refrigerator, or when the door of the refrigerating compartment is opened, and the temperature of the refrigerating compartment increases due to the inflow of outside air, the overall temperature of the refrigerating compartment is more normal than the conventional operation method using only the compressor and the refrigerating compartment fan. An additional air curtain fan may be installed in the refrigerating compartment to quickly recover to temperature. In such a recent refrigerator, a display means for informing a user of the temperature of the refrigerator compartment is attached to a predetermined portion of the outside of the refrigerator so that the user can check it directly. For a mechanical refrigerator, an appropriate temperature display method is provided. Therefore, there is a problem that the consumer's dissatisfaction is caused by not displaying the temperature of the refrigerating compartment to an external user.
