본 발명은 급속냉동을 구현하는 냉장고에 관한 것으로, 최대빙 결정 생성대(식품에 따라 다소 차이가 있으나 일반적으로 -1℃∼-5℃의 영역이다.)의 통과시간을 30분 이내로 함으로서 세포 조직의 파괴 등으로 인해 발생하는 품질 저하를 방지하고자 하는 것이다.The present invention relates to a refrigerator that implements rapid freezing, and has a cell structure by setting the maximum ice crystal generation zone (which varies depending on food, but is generally in the range of -1 ° C to -5 ° C) within 30 minutes. This is to prevent the quality deterioration caused by the destruction of.

종래에는 냉장고의 냉동을 빠르게 할 경우 통상 운전시와 동일한 사이클에 의해 운전하여 냉장실의 댐퍼(5)를 이용해 냉장실(4)로 향하는 냉기를 차단하고 냉동실(1)만을 운전시킨다. 이 경우 보통 급속 냉동시간(실험물(두께 5Cm) 500g을 -1℃에서 -5℃로 낮추는데 걸리는 시간)이 3시간 정도 걸린다. 식품내의 수분의 팽창을 막는 시간을 30분 이내로 해야 하는 급속동결 시간(실험물 500g을 -1℃에서 -5℃로 낮추는데 걸리는 시간이 30분 이내여야 한다.)의 정의에 매우 못 미치는 문제점이 있다.In the related art, when the refrigerator is rapidly refrigerated, the refrigerator is operated by the same cycle as in the normal operation to block the cold air directed to the refrigerating chamber 4 by using the damper 5 of the refrigerating chamber and to operate only the freezing chamber 1. In this case, the rapid freezing time (the time taken to lower 500 g of the specimen (5 cm thick) from -1 ° C to -5 ° C) usually takes about 3 hours. There is a problem that is very short of the definition of the rapid freezing time (the time required to lower the 500g of the test from -1 ℃ to -5 ℃ should be within 30 minutes) to prevent the expansion of water in the food within 30 minutes. .

본 발명은 이러한 점을 감안하여 발명된 것으로서, 냉장고의 냉동실을 급속 동결실(이하 급동실이라 한다)과 냉동실로 분리하고 사용자가 급동실에 식품을 넣고 급속동결을 원할 경우 주증발기와 보조팬에 의한 간냉식의 효과(이때 냉동실내의 주팬은 오프)와 급동실의 내부를 직냉판으로 감싼 직냉식의 효과로 급속 동결기능을 구현하는 냉장고에 관한 것이다.The present invention has been invented in view of this point, and the freezer compartment of the refrigerator is separated into a quick freezer compartment (hereinafter referred to as a barrel compartment) and a freezer compartment, and the user puts food in the barrel compartment and if the user wants rapid freezing in the main evaporator and the auxiliary fan. By the effect of the intercooling (at this time the main fan in the freezer is off) and the direct cooling effect of wrapping the inside of the barrel with a direct cooling plate relates to a refrigerator that implements a quick freezing function.

이를 첨부된 도면에 의거하여 설명하면 다음과 같다.This will be described based on the accompanying drawings.

제3도와 제5도에서와 같이 본 발명의 구성은 종래의 증발기(2)를 보조증발기(107)와 주증발기(102)로 분리하여 서로 직렬로 연결하고 제6도와 같이 중간에 체크밸브(117)가 설치되어 있고 냉동실(1)을 급동실(106)과 냉동실(101)로 분리하여 급동실 안에 보조팬(108)과 보조증발기(107)가 설치되어 있다.As shown in FIG. 3 and FIG. 5, the configuration of the present invention separates the conventional evaporator 2 into the auxiliary evaporator 107 and the main evaporator 102 and connects them in series with each other. ) Is installed and the freezing chamber 1 is separated into the barrel chamber 106 and the freezer chamber 101, and an auxiliary fan 108 and an auxiliary evaporator 107 are installed in the barrel chamber.

제3도와 같이 냉동실 안을 급동실과 냉동실로 나누어 사용자가 급속 동결을 원할 경우 제4도와 같은 유로로 냉기를 보낸다.As shown in FIG. 3, the inside of the freezer compartment is divided into a barrel compartment and a freezer compartment, and the user sends cold air to the flow path as shown in FIG.

이때 주팬(103)의 운전은 멈추고 보조팬(108)을 운전시켜 주증발기(102)의 냉기를 급동실에만 흘러보내게 된다.At this time, the operation of the main fan 103 is stopped and the auxiliary fan 108 is driven to flow cool air of the main evaporator 102 only to the barrel.

또한 보조증발기(107)를 직냉판으로 하여 급동실 구역을 감싸게 되어 열전도에 의해 식품의 냉동을 빠르게 진행시킨다.In addition, the secondary evaporator 107 is a direct cooling plate to surround the barrel compartment, thereby rapidly proceeding the freezing of food by heat conduction.

동시에 냉동실에로의 냉기는 단열재와 주팬의 정지에 의해 차단되고 냉장실에로의 냉기는 냉장실용 댐퍼(105)에 의해 차단된다.At the same time, the cold air to the freezer compartment is blocked by the insulation and the main fan stopped, and the cold air to the cold compartment is blocked by the refrigerator compartment damper 105.

그리하여 모든 증발기의 열을 보조팬에 의한 강제 대류와 직냉판인 보조증발기(107)에 의한 열전도에 의해 급속동결을 구현하게 된다.Thus, all the evaporator heat is realized by forced convection by the auxiliary fan and heat conduction by the auxiliary evaporator 107 which is a direct cold plate.

제6도는 본 발명의 사이클도이며 증발기가 2개도 나뉘어 직냉판인 보조발기와 팬에 의해 열전달이 되는 주증발기(102)로 구성된다.FIG. 6 is a cycle diagram of the present invention and is composed of a main evaporator 102 in which the evaporator is divided into two and the heat transfer is performed by an auxiliary erectile fan and a fan.

본 발명에서는 급속동결을 사용자가 원하는 경우 냉동실과 냉장실에로의 냉기를 차단하지만 본 발명의 다른 실시예로 주팬의 주기적인 운전과 이에 따른 냉장실용 댐퍼의 열림에 의해서나 단지 냉장실용 댐퍼의 열림에 의해 일부의 냉기를 냉장실과 냉동실에 일정주기나 온도센서의 신호에 의해 보낼 수 있다.In the present invention, if the user wants fast freezing, the cold air to the freezer compartment and the refrigerating compartment is blocked. However, in another embodiment of the present invention, only by opening the damper for the refrigerating compartment or by opening the damper for the refrigerating compartment. Therefore, some of the cold air can be sent to the refrigerating chamber and the freezing chamber by a certain period or a signal of a temperature sensor.

이와 같은 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention as follows.

급속동결이란 통상 식품이 -1℃에서 -5℃를 통과하는 시간이 30분 이내여야 한다. 그러나 식품의 종류와 식품내의수분 함유량에 따라 열부하가 다르므로 통상 표준화된 실험물(Test Package)를 사용한다. 이 물질은 육류와 유사한 수분 함유량과 물성을 갖고 있고 보통 500g을 사용한다. 종래의 냉장고는 이 물질로 실험한 결과 3시간에서 4시간 정도 걸린다. 본 발명의 열전달 효과는 냉동실 안에 급동실을 별도로 작게 두어 외부로 빠져 나가는 열량을 최소화 함에 따라 유리하다.Rapid freezing usually means that food passes from -1 ° C to -5 ° C within 30 minutes. However, since the heat load varies depending on the type of food and the water content in the food, a standardized test package is usually used. This substance has similar moisture content and physical properties to meat and usually uses 500g. The conventional refrigerator takes about 3 to 4 hours after experimenting with this material. The heat transfer effect of the present invention is advantageous by minimizing the amount of heat exiting the outside by leaving the barrel separately in the freezer compartment.
