냉장고의 급동실The barrel of the refrigerator

본 발명은 냉장고에 관한 것으로서, 특히 제품의 급속동결이 가능하도록 냉동실 내에 냉동실 온도보다 더 낮은 온도의 급동실을 구비하기 위한 급동실구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, and more particularly, to a barrel chamber structure having a barrel of a temperature lower than a freezer chamber temperature in a freezer compartment to enable rapid freezing of a product.

일반적인 냉장고는 도 1에 도시된 바와 같이 냉동실(2)과 냉장실(6)로 이루어지고, 상기 냉동실(2)의 후면에 증발기(17)와 함께 형성되는 팬(1)과, 상기 냉장실(6)은 선반(7)과 야채박스(8)로 냉기를 보내는 멀티덕트(5)로 이루어지며 각각에는 냉동실공기출구(3)와 냉장실공기출구(4)로 구성되었다.A general refrigerator includes a freezer compartment 2 and a refrigerating compartment 6, as shown in FIG. 1, a fan 1 formed together with an evaporator 17 at the rear side of the freezer compartment 2, and the refrigerating compartment 6. It consists of a multi-duct (5) for sending cold air to the shelf (7) and the vegetable box (8), each consisting of a freezer compartment air outlet (3) and the cold compartment air outlet (4).

이와같이 구성된 상태에서 팬(1)의 회전에 의해 냉기는 냉동실(2)과 냉장실(6)로 보내어지고 냉장실(6)로 보낸 냉기는 멀티덕트(5)를 통하여 냉장실(6)로 보내어져서 음식물들을 차갑게 한다.The cold air is sent to the freezer compartment 2 and the refrigerating compartment 6 by the rotation of the fan 1 in the state configured in this way, and the cold air sent to the refrigerating compartment 6 is sent to the refrigerating compartment 6 through the multi duct 5 to feed the food. Cool

그리고 냉동실(2)과 냉장실(6)을 순환한 냉기는 냉동실(2)은 냉동실공기출구(3)로, 냉장실(6)은 냉장실공기출구(4)를 통하여 다시 증발기(17) 입구로 유입되게 된다.The cold air circulated through the freezer compartment (2) and the refrigerating compartment (6) allows the freezer compartment (2) to flow into the freezer compartment air outlet (3) and the refrigerating compartment (6) to the inlet to the evaporator (17) again through the refrigerator compartment air outlet (4). do.

종래 냉장고에 있어서는 음식물의 급냉을 위하여 증발기 온도를 낮춰서 냉동실 전체를 저온으로 만드는 방법이 있으나, 이는 압축기 윤활유의 동결 및 압축기의 흡입압력의 한계저압등 제약조건과 냉동실 전체의 온도를 낮출경우 단열부하가 증가하게 되는 문제점이 발생하게 된다.In the conventional refrigerator, there is a method of making the whole freezer at a low temperature by lowering the temperature of the evaporator to quench the food. However, when the temperature of the freezer is lowered, constraints such as freezing of the compressor lubricating oil and limiting pressure of the suction pressure of the compressor are lowered. There is a problem that increases.

본 발명은 상기한 바와같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로서, 냉동실의 임의의 위치에 급동실을 형성하고, 상기 급동실에는 열을 흡수하는 흡열용 열교환기를 형성하며, 상기 흡열용 열교환기로 흡수된 열을 열전달수단을 이용해 보조증발기로 전달하는 열전모듈을 구성함으로서, 제품의 급속동결기능을 냉장고에 추가시키도록 하는데 목적이 있다.The present invention has been invented to solve the problems of the prior art as described above, forming a barrel chamber at any position of the freezer compartment, forming a heat absorbing heat exchanger for absorbing heat in the barrel chamber, By constructing a thermoelectric module that transfers the heat absorbed by the air to the auxiliary evaporator by using a heat transfer means, the purpose is to add a fast freezing function of the product to the refrigerator.

본 발명을 도 2 를 참조하여 이하에서 상세히 설명한다.The present invention is described in detail below with reference to FIG.

먼저 구성을 살펴보면 냉장실(101)과 냉동실(102)로 구분되는 냉장고 구조에 있어서, 상기 냉동실(102)의 일측에 급동실(103)을 형성하고, 상기 급동실(103)내측에는 내부열을 흡수하는 흡열핀(104)을 설치하며, 상기 흡열핀(104)으로 흡수된 열을 방열용 열전도체(105)를 이용해 보조증발기(106)로 전달하는 열전모듈(107)을 구성하였다.First of all, in the refrigerator structure divided into the refrigerating chamber 101 and the freezing chamber 102, the barrel chamber 103 is formed on one side of the freezer chamber 102, and the inside of the barrel chamber 103 absorbs internal heat. The endothermic fin 104 was installed, and the thermoelectric module 107 was configured to transfer the heat absorbed by the endothermic fin 104 to the auxiliary evaporator 106 using the heat radiating heat conductor 105.

도면중 미설명 부호 108 은 단열재를 나타낸다.In the drawing, reference numeral 108 denotes a heat insulating material.

열전모듈이란 직사각형 판모양의 것으로 전기를 흘려주면 한쪽면은 온도가 낮아지고 다른 한쪽면은 온도가 높아지는 일종의 히트펌프이며, 고온부와 저온부의 온도차가 적을수록 효율이 높아지는 특성을 갖게된다.The thermoelectric module is a rectangular plate shape, and when one is supplied with electricity, one side of the thermoelectric module is a type of heat pump that has a low temperature and the other side has a high temperature.

본 발명의 열전모듈(107)은 흡열핀(104)을 통해 급동실(103)에서 열을 흡수하여 급동실의 온도를 낮춰주고 이때 흡수된 열은 다시 열전모듈(107)에 의해 열전도체(105)를 통해 보조증발기(106)로 전달되며 이 열은 다시 보조증발기(106) 내를 흐르는 냉매로 전달되어 냉장고의 응축기(미도시)로 방출된다.The thermoelectric module 107 of the present invention absorbs heat from the barrel chamber 103 through the heat absorbing fins 104 to lower the temperature of the barrel chamber, and the absorbed heat is again caused by the thermoelectric module 107 by the thermoelectric module 107. The heat is transferred to the auxiliary evaporator 106, and this heat is transferred to the refrigerant flowing in the auxiliary evaporator 106 and discharged to the condenser (not shown) of the refrigerator.

본 시스템에서 급동실(103)은 열전모듈(107)의 저온부가 되고 보조증발기(106)는 열전모듈(107)의 고온부가 되므로 급동실(103)의 온도는 냉장고의 증발기(보조증발기) 보다 더 낮은 온도로 유지되어 제품의 급냉이 가능하게 되는 것이다.In the present system, the barrel 103 is a low temperature part of the thermoelectric module 107 and the auxiliary evaporator 106 becomes a high temperature part of the thermoelectric module 107, so the temperature of the barrel 103 is more than that of the refrigerator's evaporator (auxiliary evaporator). It is maintained at a low temperature to allow rapid cooling of the product.

이상 설명한 바와같이 본 발명의 급동실 구조는 냉장고의 냉동기능중 급동기능을 추가하여 제품의 급속동결이 가능토록 해주는 효과가 있다.As described above, the barrel structure of the present invention has an effect of enabling rapid freezing of a product by adding a barrel function of a freezer function of a refrigerator.
