The cold air supplied to the inside and discharged into the refrigerating compartment 20 is heat-exchanged in the refrigerating compartment 20, and then rises upward, and is sucked into the cold air intake 23 at the upper side of the rear side of the refrigerating compartment 20, through the refrigerating compartment return duct. 30), the cold air circulation supplied as described above is repeated until the temperature of the refrigerating chamber 20 drops below a predetermined temperature.
그런데, 냉장실의 식품에 의한 열부하가 클 경우 냉각기(30) 측의 냉기가 냉장실(20)로 공급된 후 냉장실(20) 내부에서 식품등과 열교환되는 과정에서 다량의 습기가 함유되고 상대적으로 고온으로 상승됨으로써, 냉가기측으로 복귀하면 냉각기에 과부하가 걸리게 되어 냉각기의 냉각성능의 저하되고 고온 다습한 냉기에 의해 냉각기 착상이 촉진되어 냉각기의 성능저하는 물론 제상주기가 빨라져 소비전력을 증가되는 문제점이 초래되었다.However, when the heat load by the food in the refrigerating compartment is large, a large amount of moisture is contained in the process of heat-exchanging with food and the like in the refrigerating compartment 20 after the cold air on the side of the cooler 30 is supplied to the refrigerating compartment 20. As it rises, the return to the cooler side causes an overload to the cooler, which lowers the cooling performance of the cooler and promotes the cooling of the cooler due to the high temperature and high humidity of the cooler. It became.
본 고안은 상기한 문제점을 감안하여 안출된 것으로서, 냉장실에서 냉각기측으로 복귀하는 고온 다습한 온기를 일차로 냉각시켜 냉각기측으로 복귀시킴으로써 냉각기에 착상되는 성에의 양을 감소시켜 제상주기를 길게하고 냉각기에 부과되는 부하를 감소시켜 냉각기의 성능향상은 물론 소비전력의 감소를 그 기술적 과제로 한 것이다.The present invention was devised in view of the above-mentioned problems, and by cooling the high temperature and high temperature warmth returned from the refrigerating chamber to the cooler side first and returning to the cooler side, the amount of frost formed on the cooler is reduced to lengthen the defrost cycle and impose it on the cooler.

이러한 기술적 과제를 달성하기 위하여 본 고안의 보조냉각기를 설치한 냉장고는, 냉가기측의 냉기가 송풍팬에 의해 냉장실 냉기덕트를 통해 냉장실 배면 양측 모서리의 멀티덕트로 유입되어 냉장실 내부로 공급되고 열교환 후 냉장실 배면 상측의 냉기흡입구로 흡입되어 사절부 후측의 냉장실 귀환덕트를 통해 냉각기 하측으로 복귀하도록한 냉장고에 있어서, 상기 냉장실 귀환덕트내의 일측에 보조냉각기를 설치하여 상기 보조냉각기에 의해 냉각기로 복귀하는 냉기를 예비냉각하도록 한 것이다.In order to achieve the above technical problem, in the refrigerator equipped with the subcooler of the present invention, cold air of the cooler side is introduced into the refrigerating compartment by supplying the multi ducts at both edges of the rear side of the refrigerating compartment through the refrigerating chamber cold air duct by a blower fan and A refrigerator which is sucked into the cold air inlet above the rear side of the refrigerating chamber and is returned to the lower side of the cooler through the refrigerating chamber return duct at the rear of the trimmer, wherein the subcooler is installed at one side of the refrigerating chamber return duct to return to the cooler by the subcooler. Pre-cooled.
그리고 상기 보조냉각기는 전면의 냉각부는 냉장실 귀환덕트 내부로 노출되고 후면의 방열부는 냉장고의 우레탄층을 관통하여 외상의 외부로 노출되도록 설치된 열전소자인 것을 특징으로 한 것이다.The subcooler is a thermoelectric element installed so that the cooling part of the front side is exposed to the inside of the refrigerating chamber return duct and the heat dissipation part of the rear side passes through the urethane layer of the refrigerator.
이하, 상기한 본원고안의 보조냉각기를 설치한 냉장고를 첨부한 도면을 참조하여 보다 구체적으로 설명한다.Hereinafter, with reference to the accompanying drawings a refrigerator provided with the auxiliary cooler of the present application will be described in more detail.
도 2는 본 고안에 따른 보조냉각기를 설치한 냉장고의 요부단면도이고, 도 3은 요부절개사시도로서, 냉장고의 사절부 후측에 내상을 관통하여 우레탄(40)내에, 하단전면은 냉기흡입구(23)를 통하여 냉장실(20) 내부와 연통되고 상단 전면은 냉각기(30) 하측으로 개방된 냉장실 귀환덕트(24)내에 보조냉각기가 설치되는데 상기 보조냉각기는 전면의 냉각부(2)는 상기 냉장실 귀환덕트(24)내로 노출되고 후면의 방열부(2')는 냉장고의 단열우레탄층(40)을 관통하여 외상외부로 노출되도록 설치된 열전소자(1)로 이루어진 것이다.Figure 2 is a sectional view of the main part of the refrigerator provided with the subcooler according to the present invention, Figure 3 is a perspective view of the main incision, penetrating the inner phase to the rear side of the trimmer of the refrigerator in the urethane (40), the lower front surface is the cold air intake (23) A subcooler is installed in the refrigerating chamber return duct 24 which communicates with the inside of the refrigerating chamber 20 and the upper front side is opened to the lower side of the cooler 30. The subcooler of the subcooler 2 is the refrigerating chamber return duct ( 24) the heat dissipation part 2 'exposed to the inside is made of a thermoelectric element 1 installed to penetrate the insulating urethane layer 40 of the refrigerator to the outside of the outer box.
그리고, 상기 열전소자(1) 하측의 냉장실 귀환덕트(24)의 하측에는 배수호스(3)가 우레탄층(40)내에 매설되어 그 하단이 기존의 배수호스(13)에 연결되어 있다.Further, a drain hose 3 is buried in the urethane layer 40 at the lower side of the refrigerating chamber return duct 24 below the thermoelectric element 1, and a lower end thereof is connected to the existing drain hose 13.
이와 같이 구성되는 본원고안의 보조냉각기를 설치한 냉장고는 종래와 같이 냉각기(30)측의 냉긱가 송풍팬에 의해 냉장실 냉기공급덕트를 통해 냉장실 배면 양측의 멀티덕트(21)로 안내되고 멀티덕트의 냉기토출구(22)를 통하여 냉장실(20) 내부로 토출되면 냉장실(20) 내부에 저장된 식품 및 온기와 열교환되게 된다.The refrigerator provided with the auxiliary cooler of the present invention configured as described above is guided to the multi ducts 21 on both sides of the rear side of the refrigerating chamber through the refrigerating chamber cold air supply duct by the cooling fan on the cooler 30 side as in the related art. When discharged into the refrigerating chamber 20 through the cold air discharge port 22 is heat exchanged with the food and warmth stored in the refrigerating chamber 20.
그리하여 온도가 상승되고 습도가 상승된 냉기는 상승하여 냉장실(20) 배면 상측중앙의 냉기흡입구(23)로 흡입되어 냉장실 귀환덕트(24)를 통해 냉각기측으로 복귀하게 된다.Thus, the cold air whose temperature is increased and the humidity is increased to be sucked into the cold air suction port 23 in the upper center of the rear surface of the refrigerating chamber 20 and returned to the cooler side through the refrigerating chamber return duct 24.
그런데 본 고안에서는 냉장실 귀환덕트(24)내에 보조냉각기, 즉 열전소자(1)를 설치하였으므로 냉기흡입구(23)로 흡입되어 냉각기(30)측으로 복귀하는 냉기가 상기 열전소자(1)와 열교환되어 일차 냉각된 상태로 냉각기(30)측으로 복귀하게 된다.However, in the present invention, since the subcooler, that is, the thermoelectric element 1 is installed in the refrigerating chamber return duct 24, the cold air sucked into the cold air intake port 23 and returned to the cooler 30 side is heat-exchanged with the thermoelectric element 1 to make the primary It returns to the cooler 30 side in the cooled state.
상기 열전소자(1)는 양측면에 냉각부(2)와 방열부(2')를 대향 형성시킨 것으로 냉장실 귀환덕트(24)측에는 냉각부(2)가 설치되고 반대측의 방열부(2')는 우레탄층(40)을 관통하여 냉장고 외상(50) 외부로 노출시켜 설치함으로써 냉각부(2)는 냉장실 귀환덕트(24)측의 냉기를 냉각하고 반대측의 외부로 노출된 방열부(2')에서는 방열시키게 되는 것이다.The thermoelectric element 1 is formed by opposing the cooling unit 2 and the heat dissipation unit 2 'on both sides, and the cooling unit 2 is installed on the refrigerating chamber return duct 24 side, and the heat dissipating unit 2' on the opposite side is provided. The cooling unit 2 cools the cold air on the refrigerating chamber return duct 24 side through the urethane layer 40 and exposes the outside of the refrigerator outer box 50 to the outside of the heat dissipating unit 2 'exposed to the outside on the opposite side. It will dissipate.
그리하여, 냉기흡입구(23)로 유입된 고온다습한 냉기는 상기 열전소자(1)에 의해 냉각되면서 냉기에 함유된 습기의 일부는 액화되어 열전소자(1) 하측으로 떨어지고 일부는 열전소자(1)측에 성에로 착상되어 습기가 거의 제거됨으로써 낮은 습도와 다소 낮은 온도로 일차 냉각된 냉기가 냉각기(30')측으로 복귀하게 되는 것이다.Thus, while the hot and humid cold air introduced into the cold air intake 23 is cooled by the thermoelectric element 1, a part of the moisture contained in the cold air is liquefied to fall below the thermoelectric element 1, and a part of the thermoelectric element 1. As the frost is formed on the side and the moisture is almost removed, the cold air first cooled to a lower humidity and a somewhat lower temperature is returned to the cooler 30 'side.
따라서, 냉각기(30)에 착상되는 성에의 양이 크게 감소되어 제상주기를 길게 연장시킬 수 있음은 물로 냉각기의 냉각성능이 크게 향상됨은 물론 냉각기(30)측으로 복귀하는 냉기가 보조냉각수단, 즉 열전소자(1)에 의해 일차 냉각되어 다소 낮은 온도의 냉기가 냉각기(30)측으로 귀환되게 되므로 냉각기에 가해지는 열부하를 감소시켜 냉장고의 신속한 냉각기 가능한 것이다.Therefore, the amount of frost formed on the cooler 30 can be greatly reduced, and thus the defrost cycle can be prolonged. As a result, the cooling performance of the cooler with water is greatly improved, and the cool air returned to the cooler 30 side is supplementary cooling means, that is, thermoelectric. The first cooling by the element (1) is to return the cold air of a somewhat lower temperature to the cooler 30 side, it is possible to reduce the heat load applied to the cooler to quickly cool the refrigerator.
한편, 열전소자(1)에 의한 냉각으로 액화된 물방울은 그 하측의 배수호스(3)로 유입되고 상개 배수호스(3)가 연결된 기존의 배수호스(13)를 통해 기계실측의 증발그릇으로 배출되어 증발되게 되며, 열전소자(1) 주위에 착상된 성에는 냉각기(30) 제상시 냉각기(30)측의 온기유입에 의해 냉각기(30)제상과 온도에 보조냉각기의 제상이 수행될 수 있다.Meanwhile, water droplets liquefied by cooling by the thermoelectric element 1 flow into the drain hose 3 below and discharge into the evaporation vessel of the machine room side through the existing drain hose 13 to which the upper drain hose 3 is connected. After the evaporation of the cooler 30, the defrost of the cooler 30 may be performed at the cooler 30 and the temperature by inflow of warm air from the cooler 30 side when the cooler 30 is defrosted.
따라서 도면에서는 구체적으로 도시되지 않았으나 냉장실(20) 배면 상측의 냉기흡입구(23)에는 제상시 온기가 역류하는 것을 방지하기 위하여 역류방지용 플랩을 설치하는 것이 바람직하다.Therefore, although not shown in detail in the drawing, it is preferable to install a backflow prevention flap in the cold air intake 23 on the rear side of the refrigerating chamber 20 in order to prevent backflow of warm air during defrosting.
이상에서 상세히 설명드린 바와 같이, 본 고안은 냉장실로 공급된 냉기가 열교환 냉각기측으로 복귀하는 통로인 냉장실 귀환덕트에 보조냉각수단을 설치함으로써, 냉각기에 걸리는 열부하를 감소시키고 성에의 착상을 감소시켜 냉각기의 냉각성능 향상은 물론 제상주기를 연장시킬 수 있으므로 냉장고의 성능향상과 소비전력 감소를 이룰 수 있는 것이다.As described in detail above, the present invention provides an auxiliary cooling means in the refrigerating chamber return duct, which is a passage through which the cold air supplied to the refrigerating chamber returns to the heat exchange cooler side, thereby reducing the heat load on the cooler and reducing the frost formation. In addition to improving cooling performance, the defrosting cycle can be extended, resulting in improved refrigerator performance and reduced power consumption.
