본 발명은 냉장고의 신선실 냉각 장치에 관한 것으로 보다 상세하게는, 냉장고의 신선실을 외부와 차단되도록 설치하고 열전소자를 이용하여 독립적으로 냉각시키도록 한 냉장고의 신선실 냉각장치에 관한 것이다.The present invention relates to a fresh room cooling apparatus of a refrigerator, and more particularly, to a fresh room cooling apparatus of a refrigerator installed so that the fresh chamber of the refrigerator is cut off from the outside and independently cooled using a thermoelectric element.
일반적으로 냉장고의 신선실은 냉장실내의 다른 식품에 의한 냄새의 전이를 방지하여 식품을 보다 신선하게 저장하기 위하여 설치되는 공간이다.In general, a fresh room of a refrigerator is a space installed to store food more freshly by preventing the transfer of odor by other foods in the refrigerator.
이와 같은 종래 냉장고의 신선실은 도 1 에 도시된 바와 같이, 냉장고의 사절부 바로 하측에 인출가능하게 설치되는데, 상기 신선실(35)의 배면 벽은 냉장실 냉기 토출구(34)와 대향되게 관통형성한 냉기 유입구을 통해 냉장실 내부로 공급되는 냉기의 일부가 유입되도록 구성되어 있다.As shown in FIG. 1, the drawing room of the conventional refrigerator is installed to be pulled out directly below the trimming part of the refrigerator, and the rear wall of the drawing room 35 is formed to penetrate through the cold room discharge port 34. It is configured to introduce a portion of the cold air supplied into the refrigerating chamber through the cold air inlet.
따라서 종래 냉장고의 신선실 냉각구조는 냉장실(30)내부의 다른 공간과는 격리되어 다른 식품에 의한 냄새의 전이는 어느 정도 차단되는 효과가 있으나, 신선실(35)만의 독립적인 온도제어가 불가능하고, 냉장실(30)로 공급되고 냉장실(30)내부에서 열교환된후 냉각기(20)로 복귀하여 냉각되어 다시 냉장실(30)로 공급되는 과정에서 냉기에 포함된 냄새에 의한 전이에 대하여는 마땅한 수단이 없어 신선실(35)내의 식품의 신선도를 확보할 수 없다는 문제점이 있어왔다.Therefore, the fresh room cooling structure of the conventional refrigerator is isolated from other spaces in the refrigerating room 30, so that there is an effect of blocking the transfer of odor by other foods to some extent, but independent temperature control of the fresh room 35 alone is impossible. In the process of being supplied to the refrigerating chamber 30 and heat exchanged in the refrigerating chamber 30, returning to the cooler 20, being cooled, and being supplied to the refrigerating chamber 30 again, there is no proper means for the transition by the smell contained in the cold air. There has been a problem that the freshness of the food in the fresh room 35 cannot be secured.
본 발명은 상기한 종래 문제점을 감안하여 안출된 것으로 냉장고의 신선실을 냉장실 내부 다른 공간과 차단하고 별도의 냉각장치에 의해 냉각함으로써 신선실의 온도를 최적으로 유지시킬 수 있고 냉장실 식품 및 냉장실 냉기에 의한 냄새의 전이를 방지할 수 있는 냉장고의 신선실 냉각장치의 제공을 그 기술적 과제로 한 것이다.The present invention has been made in view of the above-described conventional problems, by blocking the fresh room of the refrigerator from other spaces inside the refrigerating room and cooling by a separate cooling device, it is possible to optimally maintain the temperature of the fresh room, and to refrigerating room food and the refrigerating room cold The technical problem is to provide a fresh room cooling apparatus of a refrigerator capable of preventing the transfer of odors caused by the smell.

이와 같은 기술적 과제를 해결하기 위하여, 본 발명 냉장고의 신선실 냉각장치는 냉장실 상측의 신선실 배면을 냉장실 배면에 밀착설치하여, 냉각부는 신선실 배면과 대향되며 방열부는 냉장고의 후판 외부로 노출되도록 냉장고의 단열우레탄층내에 설치된 열전소자와, 배면은 상기 열전소자의 냉각부와 면접하고 전면은 냉장고 내상을 관통하여 상기 신선실 내부로 노출되는 전열블록과, 상기 열전소자의 방열부에 접하도록 일부분이 외부로 노출된 석션파이프로 구성되는 것을 특징으로 한 것이다.In order to solve the above technical problem, the fresh room cooling apparatus of the refrigerator of the present invention is installed in close contact with the back of the fresh room in the refrigerator compartment, the cooling unit is opposed to the back of the fresh room, the heat sink is exposed to the outside of the rear plate of the refrigerator. A thermoelectric element installed in the insulating urethane layer, the rear surface of the thermoelectric element is in contact with the cooling portion of the thermoelectric element and the front surface penetrates the inside of the refrigerator chamber exposed through the inside of the refrigerator, and a portion of the thermoelectric element in contact with the heat radiating portion It is characterized by consisting of a suction pipe exposed to the outside.
그리고, 상기 전열블록은 열전도성이 우수한 알루미늄재로 형성하되 신선실측 단면에 다수의 냉각핀을 부설한 것을 특징으로 한다.The heat transfer block may be formed of an aluminum material having excellent thermal conductivity, but a plurality of cooling fins may be attached to the end surface of the fresh chamber.
이하 본 발명을 첨부한 도면을 참조하여 보다 구체적으로 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
도 2 는 본 발명에 따른 신선실 냉각구조를 나타내는 냉장고의 요부단면도이고,도 3 은 냉장고의 배면측 요부사시도로서, 냉장고의 사절부 바로 하측의 냉장실 내에 신선실(35)이 설치되는데 신선실(31)의 배면벽이 냉장실 배면에 밀착되도록 설치한 것이다.2 is a cross-sectional view of a main part of a refrigerator showing a fresh room cooling structure according to the present invention, and FIG. 3 is a rear side main perspective view of the refrigerator, in which a fresh room 35 is installed in a refrigerating chamber immediately below a trimming part of the refrigerator. The rear wall of 31) is installed to be in close contact with the back of the refrigerating chamber.
그리하여, 기존의 냉장실 냉기덕트(31)는 하단이 신선실(35) 하측까지 하향연장되므로 멀티덕트(33) 또한 신선실 하측부터 수직으로 설치되므로 냉장실 냉기덕트(31)를 통해 멀티덕트(33)로 유입되어 냉기토출구(34)로 토출공급되는 냉장실(30) 냉기는 신선실(35)에는 전혀 공급되지 않는다.Therefore, since the lower end of the existing refrigerating chamber cold air duct 31 is extended downward to the lower side of the fresh room 35, the multi duct 33 is also installed vertically from the lower side of the fresh room, so the multi duct 33 through the refrigerating room cold air duct 31. The cold air flowed into the cold air discharge port 34 and supplied to the cold air outlet 34 is not supplied to the fresh chamber 35 at all.
따라서, 신선실(35)에는 별도의 냉각장치가 설치되는데, 신선실(35) 후측의 내상(37)과 후판(39) 사이의 우레탄층(38)내에 전원인가시 일면은 냉각되고 반대측면은 방열하는 열전소자(10)를 설치하여 냉각부(1)는 신선실(35)측을 향하게 하고 반대측의 방열부(2)는 후판을 개방하여 외부로 노출되게 한 것이다.Therefore, a separate cooling device is installed in the draw chamber 35. When power is applied in the urethane layer 38 between the inner plate 37 and the rear plate 39 at the rear of the draw chamber 35, one side is cooled and the opposite side is By installing the thermoelectric element 10 for heat dissipation, the cooling unit 1 faces the fresh chamber 35 side, and the heat dissipating unit 2 on the opposite side opens the thick plate to be exposed to the outside.
또한 상기 열전소자(10)의 두께가 우레탄층(38)비하여 상대적으로 얇게 형성되므로 상기 열전소자(10)의 냉각부(1) 전면에 열전도성이 우수한 전열블록(3)이 설치되는데, 상기 전열블록(3)은 후측단면이 상기 열전소자(1)의 냉각부(1)면에 밀착되고 전면은 냉장실(30)배면을 관통하여 신선실(35)내부로 노출되도록 한 것으로, 바람직하게는 상기 방열블록(3)의 신선실 내부측면에 다수의 냉각핀을 부설한 것이다.In addition, since the thickness of the thermoelectric element 10 is relatively thin as compared with the urethane layer 38, the heat transfer block 3 having excellent thermal conductivity is installed on the entire cooling unit 1 of the thermoelectric element 10. Block 3 has a rear end surface is in close contact with the cooling unit 1 surface of the thermoelectric element 1 and the front surface penetrates through the rear surface of the refrigerating chamber 30 and is exposed to the inside of the fresh chamber 35. A plurality of cooling fins are installed on the inner side of the fresh room of the heat radiation block (3).
또한편 본 발명의 실시예에서는 냉장고의 후판(39)을 관통하여 외부로 노출된 방열부(2) 전면에 냉각기(20)측에서 콤프레서(50)측으로 냉매가 복귀하는 석션파이프(25)의 일부를 우회시켜 배치함으로써 약 -5℃~0℃의 석션파이프(25)에 의해 방열부(2)의 방열을 촉진시키게 한 것이다.In addition, in the embodiment of the present invention, part of the suction pipe 25 in which the refrigerant returns from the cooler 20 side to the compressor 50 side on the front surface of the heat dissipation unit 2 exposed through the rear plate 39 of the refrigerator. By arranging by bypassing, the heat dissipation of the heat dissipation part 2 is promoted by the suction pipe 25 of about -5 degreeC-0 degreeC.
미설명부호 36은 신선실(36) 전면을 개폐가능하게 폐쇄하는 신선실 커버이다.Reference numeral 36 is a drawing of the drawer cover for closing the front of the drawer (36) to open and close.
이와 같이 구성되는 본 발명 냉장고의 신선실 냉각장치는 냉장실 상측에 냉장실(30) 냉기 공급과는 별도로 냉기의 공급이 이루어진다.In the fresh room cooling apparatus of the refrigerator of the present invention configured as described above, cold air is supplied to the upper side of the refrigerator compartment separately from the cold room 30 cold air supply.
즉 앞에서 설명한 열전소자(1)에 의해 독립적으로 냉각이 이루어지는데 도면에는 구체적으로 도시되지는 않았으나 신선실(35) 내부에 온도감지센서를 설치하여 이에 의해 감지된 신선실(35) 내부의 온도가 일정온도이상이면 냉장고의 제어부가 이를 판단하여 열전소자(1)에 전원을 인가하게 된다.That is, the cooling is independently performed by the thermoelectric element 1 described above, but although not specifically illustrated in the drawing, a temperature sensor is installed in the drawing chamber 35 to detect the temperature inside the drawing chamber 35. If the temperature is above a predetermined temperature, the control unit of the refrigerator determines that the power is applied to the thermoelectric element 1.
따라서 냉각부(1)가 급속히 냉각되고 전열블록(3)이 냉각되므로 신서실(35)내부로 노출된 전열블록(3)과 신선실(35)내 냉기와의 사이에 열교환이 이루어지면서 신선실(35)을 냉각하게 된다.Therefore, since the cooling unit 1 is rapidly cooled and the heat transfer block 3 is cooled, the heat exchange is performed between the heat transfer block 3 exposed inside the new chamber 35 and the cold air in the fresh chamber 35. Cool 35.
게다가, 전열블록(3)의 전면에 다수의 냉각핀을 부설한 경우 전열블록(3)의 열교환 효율을 보다 상승시킬 수 있다.In addition, when a plurality of cooling fins are provided on the front surface of the heat transfer block 3, the heat exchange efficiency of the heat transfer block 3 can be further increased.
또한 상기 냉각부(1)의 냉각과 동시에, 상기 냉각부(1)의 반대측에 배치된 방열부(2)는 고온으로 상승되면서 대기와의 대류에 의해 열이 방출되는데 본 고안에서는 약-5℃~0℃의 석션파이프(25)의 일부를 우회시켜 상기 방열부(2)의 전면에 배치하였으므로 보다 신속한 방열이 이루어지게 된다.In addition, at the same time as the cooling of the cooling unit 1, the heat dissipation unit 2 disposed on the opposite side of the cooling unit 1 rises to a high temperature and heat is released by convection with the atmosphere. Since a portion of the suction pipe 25 at ˜0 ° C. is bypassed and disposed on the front surface of the heat dissipation unit 2, heat dissipation is more rapid.
한편, 열전소자(10)의한 신선실의 독립냉각이 수행되어 신선실온도가 일정온도 이하로 하강하면 신선실(35)내의 온도감지센서가 이를 감지하고 상기 온도감지센서의 신호를 판단한 제어부가 열전소자(10)로 공급되는 전원을 차단함으로써 신선실(35)의 냉각이 종료되는 것이다.On the other hand, the independent cooling of the drawing room by the thermoelectric element 10 is carried out when the drawing room temperature falls below a certain temperature, the temperature sensor in the drawing room 35 detects this and the control unit that judges the signal of the temperature sensing sensor is thermoelectric The cooling of the drawing chamber 35 is terminated by cutting off the power supplied to the element 10.
이와 같이 구성된 본 발명 냉장고의 신선실 냉각장치는 신선실을 냉각실과 차단하고 신선실의 냉각을 냉장실의 냉기공급과 별도로 열전소자에 의해 독립적으로 수행하도록 함으로써, 신선실의 온도를 최적으로 유지할 수 있음은 물론 냉장실 식품이나 냉기에 의한 냄새의 전이를 근본적으로 방지하여 신선실에 수납되는 식품의 신선도를 최적화할 수 있는 것이다.The fresh room cooling apparatus of the refrigerator of the present invention configured as described above may keep the temperature of the fresh room optimally by blocking the fresh room from the cooling room and performing cooling of the fresh room independently by a thermoelectric element separately from supplying cold air of the refrigerating room. Of course, it is possible to optimize the freshness of the food stored in the fresh room by fundamentally preventing the transfer of odor by cold food or cold food.
