본 발명은 양문형 냉장고의 전환룸 냉각에 있어서 냉동실의 냉기를 직접 유입시켜 전환룸을 냉각하지 않고 별도의 2차 냉각기를 이용하여 전환룸을 냉각시키는 방식의 양문형 냉장고의 냉장실 전환룸 냉각구조에 관한 것이다.The present invention relates to a refrigerating compartment switching room cooling structure of a double-door refrigerator in a cooling system of the double door type refrigerator in which a cold air of a freezer compartment is directly introduced to cool the switching room without cooling the switching room. .

일반적으로, 양문형 냉장고는 도 1에 도시된 바와같이 일측은 냉동실(1)을 이루고, 타측은 냉장실(2)을 구성하며, 냉장실에는 예를들어 서랍실과 같은 전환룸(3)이 마련되어 있다.In general, as shown in FIG. 1, a double-sided refrigerator forms a freezing compartment 1 on one side, a refrigeration chamber 2 on the other side, and a switching room 3 such as a drawer chamber, for example, in the cold compartment.

이러한 전환룸(3)의 냉각을 위하여 종래 양문형 냉장고에서는 측벽(4)에 냉동실과 통하는 냉기 공급용 홀(5)과 귀환 홀(6)을 형성하여 냉동실의 냉기를 직접 순환시켜 냉각하는 방식을 채용하였다. In order to cool the switching room 3, the conventional double-door refrigerator adopts a method of forming a cold air supply hole 5 and a return hole 6 in the side wall 4 and circulating the cold air in the freezer compartment directly to cool it. It was.

그러나, 위와같이 냉동실의 냉기를 냉장실의 전환룸(3) 냉각에 직접 이용하는 것은 냉동실의 냉기와 전환룸의 냉기가 혼합되어 냉동실과 전환룸을 순환하게 됨에 따라 전환룸의 수분에 의해 냉동실의 증발기에 성애 착상이 증대되는 한편, 전환룸은 지나치게 습도가 저하됨에 따라 전환룸에 보관하는 식품의 신선도를 유지할 수 없게 되는 문제가 있었다.However, the use of the cold air of the freezer compartment for cooling the switching room 3 of the refrigerating chamber as described above is mixed with the cold air of the freezing chamber and the cold air of the switching room, and circulates between the freezing chamber and the switching room, so that the freezing chamber evaporates to the evaporator of the freezing chamber. While increasing the concept of sexual love, the conversion room has a problem that can not maintain the freshness of the food stored in the conversion room as the humidity is too low.

따라서, 본 발명은 상술한 종래 양문형 냉장고의 전환룸 냉각구조에 따른 문제점을 해소하기 위하여 냉장실의 전환룸 냉각을 위하여 냉동실의 냉기를 직접 순 환시키지 않고 냉동실의 냉기를 이용한 별도의 2차 냉각방식을 채용한 냉장실 전환룸의 냉각구조의 제공을 목적으로 한다.Accordingly, the present invention provides a separate secondary cooling method using the cold air of the freezer compartment without directly circulating the cold air of the freezer compartment for cooling the switching room of the refrigerating compartment in order to solve the problems caused by the switching room cooling structure of the conventional double-door refrigerator. It aims at providing the cooling structure of the refrigerating-room switching room which was adopted.

상기한 목적을 달성하기 위한 본 발명에 따른 냉장고 냉장실의 전환룸 냉각구조는 전환룸을 냉장실의 통상적인 설정 온도보다 낮은 온도로 냉각하도록 냉동실의 증발기와 별도의 독립된 2차 냉각기를 포함하며, 상기 2차 냉각기는 증발기에 인접하여 배치된 제 1 열교환부와, 냉장실의 전환룸을 냉각하도록 제 2 열교환부를 포함하며, 상기 제 1 열교환부는 냉동실의 증발기에 인접하여 냉각되고 냉매를 강제순환시키는 모터가 제공된 관로를 통하여 냉장실의 전환룸에 배치된 제 2 열교환부와 연결되어 폐회로를 형성하여 전환룸을 냉각하도록 구성된다.The switching room cooling structure of the refrigerator refrigerating compartment according to the present invention for achieving the above object comprises a secondary cooler separate from the evaporator of the freezer compartment to cool the conversion room to a temperature lower than the normal set temperature of the refrigerating compartment, The secondary cooler includes a first heat exchanger disposed adjacent to the evaporator and a second heat exchanger to cool the switching room of the refrigerating compartment, wherein the first heat exchanger is provided adjacent to the evaporator of the freezer compartment and provided with a motor for forced circulation of the refrigerant. It is connected to the second heat exchanger disposed in the conversion room of the refrigerating chamber through a conduit to form a closed circuit to cool the conversion room.

이하, 본 발명의 실시예를 도시한 첨부 도면을 참고하여 본 발명을 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings showing an embodiment of the present invention will be described in detail the present invention.

도 2에는 본 발명에 따라 냉동실(10)의 증발기(11)와 별도의 독립된 2차 냉각기(12)를 이용하여 냉장실의 전환룸을 냉각하도록 된 구성이 도시되어 있다. 본 명세서에서 전환룸(13)은 예를들어 양문형 냉장고의 냉장실에서 통상 냉장실 온도는 0 - 7℃로 설정되지만 육류 저장과 같이 -4℃ 내지 0℃로 저장해야 하는 경우에 기존의 저장실 온도가 적합하지 않으며, 이에 대하여 냉동실의 냉기를 이용하여 냉장실 설정 온도 보다 낮은 온도로 식품등을 보관할 수 있도록 저장실내에 주로 하측에 공간을 형성한 것을 말한다.2 shows a configuration in which the switching room of the refrigerating chamber is cooled by using an independent secondary cooler 12 separate from the evaporator 11 of the freezing chamber 10 according to the present invention. In the present specification, the conversion room 13 is typically set at 0-7 ° C. in a refrigerating room of a double door refrigerator, but the existing storage room temperature is suitable when the storage room should be stored at -4 ° C. to 0 ° C., such as meat storage. On the contrary, it refers to a space formed mainly in the lower side of the storage compartment so that food can be stored at a temperature lower than the set temperature of the refrigerating compartment using cold air of the freezer compartment.

본 발명에 따른 2차 냉각기(12)는 아세틸렌글리콜과 같은 2차 냉매가 폐회로 를 이루는 관로(14)를 통하여 순환되는데, 상기 일측의 열교환부(15)는 냉동실의 증발기(11)에 인접 배치되어 증발기의 냉기에 의해 냉매가 냉각되는 한편, 냉동실의 벽(16)을 통하여 냉장실로 관로가 연장된 타측의 열교환부(17)는 냉장실(18)의 전환룸(13) 상측에 배치되어 열교환에 의해 전환룸을 냉각하도록 구성된다. 상기 2차 냉각기의 2차 냉매는 순환펌프(20)에 의해 폐회로에서 강제순환된다.The secondary cooler 12 according to the present invention is circulated through a conduit 14 in which secondary refrigerant such as acetylene glycol forms a closed circuit, and the heat exchange part 15 of one side is disposed adjacent to the evaporator 11 of the freezer compartment. While the refrigerant is cooled by the cold air of the evaporator, the heat exchange part 17 on the other side of which the conduit extends through the wall 16 of the freezer compartment to the refrigerating compartment is disposed above the switching room 13 of the refrigerating compartment 18, Configured to cool the conversion room. The secondary refrigerant of the secondary cooler is forcedly circulated in the closed circuit by the circulation pump 20.

전환룸(13)을 냉각하기 위한 냉각기 구성은 냉동실로부터 연장된 2차 냉매 관로(14)가 냉동실 벽(16)을 관통하여 전환룸 상측의 커버요소(21) 저면으로 연장되어 열교환부(17)를 구성함으로써, 상기 커버요소(21) 아래쪽의 전환룸(13) 위에서 열교환에 의해 주변 공기를 냉각시킴으로써 전환룸을 냉각시키게 된다.The cooler configuration for cooling the switching room 13 has a secondary refrigerant conduit 14 extending from the freezing chamber penetrating through the freezing chamber wall 16 and extending to the bottom of the cover element 21 at the upper side of the switching room so that the heat exchange unit 17 can be used. By the configuration, the conversion room is cooled by cooling the ambient air by heat exchange on the conversion room 13 below the cover element 21.

이와같이 냉동실의 증발기와 별도의 냉각기를 이용하여 냉장고의 냉장실내에서 냉장실의 통상적인 설정 온도 보다 낮은 온도에서 특정 식품들을 보관할 수 있게 된다.As such, it is possible to store certain foods at a temperature lower than the normal set temperature of the refrigerating compartment in the refrigerating compartment of the refrigerator by using an evaporator of the freezer compartment and a separate cooler.

본 발명에 따라, 냉동실의 증발기와 별도의 2차 냉매를 이용한 2차 냉각기를 구성하여 전환룸을 냉각시킴으로써, 종래 냉동실의 벽에 홀을 형성하여 냉동실의 냉기가 유동하게 하여 전환룸을 냉각시키는 냉각 구조의 경우 전환룸에서는 과도하게 습도가 저하되어 식품의 신선도가 떨어지는 문제가 방지되고, 아울러 전환룸에서의 습기를 함유한 냉기가 냉동실 증발기에서 냉각됨에 따라 과도한 성애 발생의 문제가 방지되는 효과가 있다. According to the present invention, by forming a secondary cooler using an evaporator of the freezer compartment and a separate secondary refrigerant to cool the conversion room, a hole is formed in the wall of the conventional freezer compartment to cool the flow of the freezer compartment to cool the conversion room. In the case of the structure, excessive humidity is lowered in the conversion room to prevent the freshness of the food, and also, as the cold air containing moisture in the conversion room is cooled in the freezer evaporator, the problem of excessive sexual occurrence is prevented. .
