Abstract

본 고안은 열전모듈을 이용한 냉온장고와 이 냉온장고의 제어방법에 관한 것으로서, 특히 냉장 저장실의 온도 냉각시 발생하는 열을 이용하여 온장 저장실의 온도를 상승시켜주는 온도조절 메카니즘을 구성하여 냉온장고의 냉장/온장 동작시열효율이 뛰어나고, 또한 냉각팬을 온/오프 제어하여 외부 열교환실의 온도를 조절하여 줌으로써, 냉온장고가 설치된 주위온도에 상관없이 냉장 저장실과 온장 저장실의 온도를 항상 원하는대로 조정할 수 있는 열전모듈을 이용한 냉온장고와이 냉온장고의 제어방법에 관한 것이다.The present invention relates to a cold storage cabinet using a thermoelectric module and a control method of the cold storage cabinet, and in particular, by configuring a temperature control mechanism that raises the temperature of the temperature storage compartment using heat generated during the temperature cooling of the refrigerator storage compartment. Excellent heat efficiency during refrigeration / heating operation, and by controlling the temperature of the external heat exchange chamber by controlling the cooling fan on / off, the temperature of the cold storage room and the cold storage room can be adjusted as desired regardless of the ambient temperature where the cold storage is installed. The present invention relates to a control method of a cold / hot refrigerator using a thermoelectric module.

종래의 냉온장고는 냉장에서 온장 혹은 온장에서 냉장으로 그 기능이 절환될 경우 저장실(6)의 내부온도가 대단히 완만하게 변화하므로 소기의 목적을 달성하기가 매우 어렵고, 또한 제3, 제4 열교환판(12A)(12B)이 설치된 외부 열교환실(9)의온도에 따라 저장실(6)의 온도가 크게 좌우되므로 종래 냉온장고가 설치된 주변온도가 높거나 낮을 경우 냉온장고의 성능을 충분히 발휘하지 못하게 된다.Conventional cold and cold refrigerator is very difficult to achieve the intended purpose because the internal temperature of the storage compartment (6) changes very slowly when the function is switched from refrigeration to warming or warming to refrigeration, and also the third, fourth heat exchange plate Since the temperature of the storage compartment 6 is largely dependent on the temperature of the external heat exchange chamber 9 in which the 12A and 12B are installed, the performance of the cold compartment may not be sufficiently exhibited when the ambient temperature in which the conventional cold compartment is installed is high or low. .

즉, 주변온도가 높은곳에서 냉장고로 사용할 경우 외부 열교환실(9)에 설치된 제3, 제4 열교환판(12A)(12B)의 방열특성이크게 떨어지게 되고, 이에따라 내부 열교환실(8)에 설치된 제1, 제2 열교환판(11A)(11B)의 흡열특성이 떨어져 저장실(6)의 온도를 충분히 내릴 수가 없고, 주변온도가 낮은곳에서 온장고로 사용할 경우 외부 열교환실(9)에 설치된 제3, 제4 열교환판(12A)(12B)의 흡열특성이 크게 떨어지게 되어 결국에는 내부 열교환실(8)에 설치된 제1, 제2 열교환판(11A)(11B)의 방열특성이 떨어져 저장실(6)의 온도를 충분히 올릴 수 없게 되는 문제점이 있는 것이다.That is, when used as a refrigerator at a high ambient temperature, the heat dissipation characteristics of the third and fourth heat exchange plates 12A and 12B installed in the external heat exchange chamber 9 are greatly decreased, and thus, the heat exchange characteristics of the third heat exchange chamber 12 are installed in the internal heat exchange chamber 8. The third and second heat exchange plates 11A and 11B have poor endothermic properties, and thus, the temperature of the storage compartment 6 cannot be lowered sufficiently. The heat absorbing characteristics of the fourth heat exchange plates 12A and 12B are greatly reduced, and eventually, the heat dissipation characteristics of the first and second heat exchange plates 11A and 11B installed in the internal heat exchange chamber 8 are inferior. There is a problem that can not raise the temperature of.

따라서, 본 발명은 상기 문제점을 해결하기 위해 냉장 저장실과 온장 저장실을 별도로 구성하고, 냉장 저장실의 온도 냉각시 발생하는 열을 이용하여 온장 저장실의 온도를 상승시켜 주는 온도조절 메카니즘을 구성하여 냉온장고의 냉장/온장동작시 열효율이 뛰어나고, 또한 냉각팬을 온/오프 제어하여 외부 열교환실의 온도를 조절하여 줌으로써, 냉온장고가 설치된 주위온도에 상관없이 냉장 저장실과 온장 저장실의 온도를 항상 원하는대로 조정할 수 있는 열전모듈을 이용한 냉온장고와 이 냉온장고의 제어방법이다.Therefore, in order to solve the above problems, the present invention comprises a cold storage compartment and a warm storage compartment separately, and configures a temperature control mechanism that raises the temperature of the cold storage compartment using heat generated during the temperature cooling of the cold storage compartment. Excellent thermal efficiency during refrigeration / heating operation, and by controlling the temperature of the external heat exchange chamber by controlling the cooling fan on / off, the temperature of the cold storage compartment and the cold storage compartment can always be adjusted as desired regardless of the ambient temperature where the cold storage is installed. It is a cold / hot refrigerator using a thermoelectric module and a control method of the cold / hot refrigerator.
