본 발명은, 냉장고에 관한 것으로서, 보다 상세하게는, 냉장실의 온도와 별도의 온도로 독립적으로 보관가능한 보조저장실을 구비한 냉장고에 있어서, 각 식품이 가장 오래 보관되는 최적의 온도에서 식품의 수분 증발을 억제하며, 오랜 기간동안 식품을 보관하게 할 수 있는 보조저장실을 갖는 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a refrigerator having an auxiliary storage room that can be stored independently at a temperature separate from the temperature of a refrigerating chamber, wherein water is evaporated at an optimal temperature at which each food is stored for the longest time. The present invention relates to a refrigerator having an auxiliary storage room capable of suppressing food and storing food for a long time.

일반적으로 냉장고는 기본적으로 냉동실과 냉장실을 구비하고 있다. 냉동실은 식품을 동결시키거나 빙점이하의 온도에서 식품을 저장한다. 냉장실은 빙점에 가까운 저온에서 식품을 신선한 상태로 보관하여 식품이 변질되거나 부패하는 것을 방지한다. 또한, 냉장실의 하부에는 보조저장실을 별도로 설치하여 야채와 같은 식품을 보관한다.In general, a refrigerator basically includes a freezer compartment and a refrigerating compartment. The freezer freezes food or stores food at temperatures below freezing. The fridge keeps food fresh at low temperatures near freezing to prevent it from deteriorating or decaying. In addition, a secondary storage compartment is separately installed in the lower part of the refrigerating compartment to store food such as vegetables.

한편, 종래의 일반적인 보조저장실의 구성은 냉기 공급만을 제어하여 냉장보관토록 하는 것은 가능하지만, 냉장실의 온도보다 더 높은 온도로 보관해야 하는 식품(예를 들면, 바나나와 같은 열대 과일)의 경우에는 냉장실보다 더 높은 온도로 보관하는 것이 불가능하였다.On the other hand, the configuration of the conventional secondary storage compartment can control the refrigeration only to control refrigeration, but in the case of food (for example, tropical fruits such as bananas) that must be stored at a temperature higher than the temperature of the refrigerator compartment, the refrigerator compartment It was not possible to store at higher temperatures.

이러한 문제점을 해결하기 위해 한국특허공개 제2002-77423에는 보조저장실의 온도를 냉장실의 온도보다 더 높게 하거나 더 낮게 할 수 있는 구성이 개시되어 있다. 보조저장실에는 냉기를 공급하는 구성과 히터에 의해 열풍을 공급하는 구성을 통해 보조저장실의 온도를 냉장실의 온도보다 더 높게 유지하는 것이 가능하다.In order to solve this problem, Korean Patent Laid-Open Publication No. 2002-77423 discloses a configuration in which the temperature of the auxiliary storage chamber is higher or lower than the temperature of the refrigerating chamber. It is possible to maintain the temperature of the auxiliary storage chamber higher than the temperature of the refrigerating chamber through the configuration of supplying cold air to the auxiliary storage chamber and the configuration of supplying hot air by the heater.

그러나, 상기 구성에서는 냉기와 열풍이 직접 보조저장실 내부를 통과하여 보관식품에 접촉하도록 구성됨으로써, 식품의 수분이 쉽게 증발하여 보관기간이 단축되는 단점이 있으며, 그 구성이 매우 복잡하다는 문제점이 있다.However, in the above configuration, since the cold and hot air directly pass through the inside of the auxiliary storage room to be in contact with the stored food, there is a disadvantage in that moisture of the food is easily evaporated and the storage period is shortened, and the configuration is very complicated.

따라서, 본 발명의 목적은, 야채 및 과일과 같은 식품을 냉장실의 온도보다 더 높거나 낮게 보관가능하며, 보관되는 식품의 수분증발을 최대한 억제하여 식품을 장기간 원형상태로 보관할 수 있는 보조저장실을 갖는 냉장고를 제공하는 것이다.Therefore, an object of the present invention is to have a secondary storage room capable of storing foods such as vegetables and fruits higher or lower than the temperature of the refrigerating room, and keeping the food in a circular state for a long time by suppressing water evaporation of the stored foods as much as possible. To provide a refrigerator.
