본 발명은 냉장고에 관한 것으로, 더욱 상세하게는 하나의 증발기를 이용하여 냉동실을 순환하는 냉기유로와 냉장실을 순환하는 냉기유로를 분리시킬 수 있는 독립냉각 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to an independent cooling refrigerator capable of separating a cold air passage circulating a freezer compartment and a cold air passage circulating a refrigerating compartment using one evaporator.

일반적으로 냉장고는 냉매가 압축 - 응축 - 팽창 - 증발하는 냉동사이클을 반복함에 따라 고내를 저온화시켜 음식물을 일정기간 동안 신선하게 유지시켜 주는 장치로서 생활에 있어서 필수품중 하나이다.In general, a refrigerator is a device that keeps food fresh for a certain period of time by reducing the temperature in the refrigerator as the refrigerant is repeatedly compressed, condensed, expanded, and evaporated.

이와 같은 냉장고는 저온/저압의 가스 냉매를 고온/고압의 가스 냉매로 승온/승압하는 압축기와, 상기 압축기로부터 유입된 냉매를 외기에 의해 응축시키는 응축기와, 다른 부분의 직경에 비해 협소한 직경으로 이루어져 상기 응축기로부터 유입된 냉매를 감압시키는 팽창밸브와, 상기 팽창밸브를 통과한 냉매가 저압상태에서 증발됨에 따라 고내의 열을 흡수하는 증발기를 기본 부품으로 하여 냉동사이클을 구성한다.Such a refrigerator includes a compressor for raising / heating a low temperature / low pressure gas refrigerant to a high temperature / high pressure gas refrigerant, a condenser for condensing the refrigerant introduced from the compressor by outside air, and a narrow diameter compared to the diameter of other parts. It consists of an expansion valve for reducing the refrigerant introduced from the condenser, and the evaporator which absorbs the heat in the refrigerator as the refrigerant passing through the expansion valve in a low pressure state as a basic component constitutes a refrigeration cycle.

이하, 첨부된 도면을 참조하여 일반적인 냉장고의 구조 및 작용를 설명하면 다음과 같다.Hereinafter, a structure and an operation of a general refrigerator will be described with reference to the accompanying drawings.

먼저, 도 1a에 도시된 바에 따르면, 상기 냉장고는 증발기(4)에 의해 열교환된 냉기가 직접 유입되어 약 -18℃의 고내 온도를 유지하고 있는 냉동실(1)과, 상기 냉동실 내의 냉기가 유입되어 약 0~7℃의 고내 온도를 유지하고 있는 냉장실로 크게 구분되며, 상기 냉동실의 배면 아래에 기계실(5)이 구비된다.First, as shown in FIG. 1A, the refrigerator includes a freezer compartment 1 in which cold air heat exchanged by the evaporator 4 is directly introduced to maintain an internal temperature of about −18 ° C., and cold air in the freezer compartment is introduced. Largely divided into a refrigerating chamber that maintains an internal temperature of about 0 ~ 7 ℃, the machine room 5 is provided under the back of the freezing chamber.

그리고, 상기 증발기(4)의 상부에는 증발기를 지나면서 저온화된 냉기를 냉동실(1)로 강제 순환시키는 송풍팬(6)과 상기 송풍팬을 구동하는 모터가 구비되며, 상기 증발기의 전면에는 냉동실의 고내 공간과 상기 증발기가 설치되는 공간을 구획하는 내측판(7)에 의해 냉기덕트(10)가 형성된다. 그리고, 상기 내측판(7)에는 냉동실과 통하는 다수의 냉기 토출구(11)가 형성되며, 상기 냉기덕트(10)의 하단에는 냉동실을 순환하면서 고온화된 냉기가 다시 증발기(4)로 유입되는 냉기 흡입구(13)가 형성된다.In addition, an upper part of the evaporator 4 is provided with a blowing fan 6 for forcibly circulating the cold air cooled through the evaporator to the freezing chamber 1 and a motor for driving the blowing fan. The cold air duct 10 is formed by the inner plate 7 partitioning the inner space of the refrigerator and the space in which the evaporator is installed. In addition, a plurality of cold air outlets 11 are formed in the inner plate 7 and communicate with the freezer compartment, and a cold air inlet in which hot air is introduced into the evaporator 4 while circulating the freezer compartment at the lower end of the cold air duct 10. (13) is formed.

도 1b에 도시된 바에 따르면, 상기 냉동실(1)의 일 측면에 배리어(3)에 의해 냉동실과 구획되는 냉장실(2)이 구비되며, 상기 배리어(3)의 상, 하부에는 냉동실로 토출된 냉기중 일부가 냉장실로 토출되는 냉기 연통구(3a)와 상기 냉장실(2)을 순환하여 고온화된 냉기가 다시 냉동실(1)로 유입되는 냉기 연통구(3b)가 각각 형성된다.As shown in FIG. 1B, a refrigerating compartment 2 partitioned from the freezing compartment by a barrier 3 is provided at one side of the freezing compartment 1, and cold air discharged into the freezing compartment above and below the barrier 3 is provided. Some of the cold air communication port (3a) is discharged to the refrigerating chamber and the cold air communication port (3b) is formed to circulate the refrigerating chamber (2) to the high temperature cold air flows back into the freezing chamber (1).

이와 같이 구성된 냉장고는 냉동실(1) 및 냉장실(2) 내에 음식물을 채운 상태에서 전원을 인가하면 기계실의 압축기가 콘트롤러(도시 생략)의 제어 신호를 받아 작동되면서 전술한 바와 같은 냉동사이클에 의해 상기 증발기(4)에 열교환 환경이 조성된다. 따라서, 상기 증발기를 통과하는 냉기는 흡열작용에 의해 저온화되며, 송풍팬(6)의 작동에 의해 냉기덕트(10)로 토출된다. 계속해서, 상기 냉기는 냉기 토출구(11)를 통해 냉동실(1)로 유입되고, 상기 냉기 중 일부는 냉기 연통구(3a)를 통해 냉장실(2)로 유입된다. 이 후, 상기 냉동실 및 냉장실을 순환하면서 고온화된 냉기는 다시 흡입구(13)를 통해 증발기(4)로 유입되는 냉기 순환구조를 이루게 된다.The refrigerator configured as described above is operated by receiving a control signal from a controller (not shown) in the freezer compartment 1 and the refrigerating compartment 2 while supplying power in a state in which food is filled in the freezer compartment 1 and the refrigerating compartment 2. In (4), a heat exchange environment is created. Therefore, the cold air passing through the evaporator is lowered by the endothermic action, and is discharged to the cold air duct 10 by the operation of the blower fan 6. Subsequently, the cold air flows into the freezing chamber 1 through the cold air discharge port 11, and some of the cold air flows into the cold storage chamber 2 through the cold air communication port 3a. Thereafter, the cold air that has been heated while circulating the freezing compartment and the refrigerating compartment has a cold air circulation structure introduced into the evaporator 4 through the suction port 13 again.

즉, 상술한 바와 같은 냉장고는 증발기(4)를 통해 열교환된 냉기 중 일부가 냉동실(1)을 경유하여 냉장실(2)로 투입되는 구조이다. 이 경우, 비록 냉장실의 설정온도가 냉동실에 비해 고온이라 할지라도 냉기의 풍량이 적음으로 인해 냉장실의 냉각 효율이 떨어지기 마련이다.That is, the refrigerator as described above has a structure in which some of the cold air heat exchanged through the evaporator 4 is introduced into the refrigerating chamber 2 via the freezing chamber 1. In this case, even though the set temperature of the refrigerating compartment is higher than that of the freezing compartment, the cooling efficiency of the refrigerating compartment is inferior due to the small amount of cold air.

뿐만 아니라, 냉동실(1)과 냉장실(2)의 냉기가 서로 교류됨에 따라 고내에 저장된 음식물의 냄새가 서로 간섭하게 되는 문제가 야기되었다. 일반적으로, 냉장실에 수납되는 냉장 대상물은 냉동 대상물에 비해 냄새의 농도가 짙은 것으로, 이러한 냉장 대상물의 냄새가 냉동실로 유입되어 냉동 대상물에 배게 된다.In addition, as the cold air in the freezer compartment 1 and the refrigerating compartment 2 are interchanged with each other, the problem that the smell of food stored in the refrigerator interferes with each other. In general, the refrigerated object accommodated in the refrigerating chamber is a concentration of the smell is higher than the refrigeration object, the smell of such a refrigerated object is introduced into the freezing chamber to be incorporated into the freezing object.

이러한 문제점을 해결하기 위해, 냉동실의 냉기덕트와 냉장실의 냉기덕트를 서로 분리시키고, 상기 각각의 냉기덕트에 증발기를 따로 구비한 냉장고가 제시되었다. In order to solve this problem, a refrigerator having a cold air duct of a freezer compartment and a cold air duct of a refrigerating compartment is separated from each other, and each of the cold air ducts has a separate evaporator.

그러나, 이 경우에 고가의 증발기를 2개씩이나 구비함에 따른 비용의 부담 뿐만 아니라, 냉동사이클의 구조가 복잡해짐에 따라 냉장고의 단가가 상승하는 문제가 야기되었다.However, in this case, as well as the burden of the cost of having two expensive evaporators, as well as the structure of the refrigeration cycle is complicated, the cost of the refrigerator increases.

본 발명은 상기 문제점을 해결하기 위해 안출된 것으로, 본 발명의 목적은 하나의 증발기를 구비함에도 불구하고 냉장실의 냉기유로와 냉동실의 냉기유로를 각각 분리하여 독립적으로 냉각시킬 수 있는 독립냉각 냉장고를 제공하는 것이다.The present invention has been made to solve the above problems, an object of the present invention is to provide an independent cooling refrigerator that can be independently cooled by separating the cold air flow path of the refrigerating compartment and the cold air flow path of the freezing compartment, respectively, even though one evaporator is provided. It is.

상기 목적을 달성하기 위해, 본 발명에 따른 독립냉각 냉장고는 냉동실측 냉기유로와, 상기 냉동실측 냉기유로와 분리된 냉장실측 냉기유로와, 냉동실측 냉기와 냉장실측 냉기가 공통으로 지나면서 열교환되는 증발기와, 상기 냉동실측 냉기유로와 냉장실측 냉기유로에 각각 구비되며 냉기를 강제 순환시키는 송풍팬을 포함 한다.In order to achieve the above object, the independent refrigeration refrigerator according to the present invention is an evaporator in which a freezer compartment side cold air flow path, a refrigerating compartment side cold air flow path separated from the freezer compartment side cold air flow path, and a freezer compartment side cold air and a cold compartment side cold air pass through the heat exchange in common. And a blowing fan provided in the freezing compartment side cold air passage and the refrigerating compartment side cold air passage, respectively, forcibly circulating cold air.

이 때, 상기 증발기는 냉동실측 냉기와 열교환되는 면적이 냉동실측 냉기와 열교환되는 면적보다 크다.At this time, the area in which the evaporator exchanges heat with the freezer compartment cold side is larger than the area exchanged with the freezer compartment cold side.

따라서, 본 발명에 따른 독립냉각 냉장고는 냉동실을 순환하는 냉기와 냉장실을 순환하는 냉기가 하나의 증발기를 통해 열교환됨에도 불구하고, 냉기유로가 서로 분리되어 있어 서로 간섭이 없는 독립냉각이 가능하다.Therefore, in the independent cooling refrigerator according to the present invention, even though the cold air circulating in the freezer compartment and the cold air circulating in the refrigerating compartment are heat exchanged through one evaporator, the cold air flow paths are separated from each other, thereby enabling independent cooling without interference with each other.

이하, 본 발명의 바람직한 실시예에 따른 독립냉각 냉장고를 첨부된 도면을 참조하여 보다 상세하게 설명하면 다음과 같다.Hereinafter, an independent cooling refrigerator according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

먼저, 도 3은 본 발명에 따른 독립냉각 냉장고의 구성을 개략적으로 나타낸 구성도로서, 본 발명에 따른 독립냉각 냉장고는 배리어(3)를 중심으로 냉동실(1)과 냉장실(2)이 서로 구획되며, 상기 냉동실을 순환하는 냉기유로(A)와 냉장실을 순환하는 냉기유로(B)가 분리된다. 이 때, 상기 냉동실측 냉기유로(A)와 냉장실측 냉기유로(B)가 서로 분리되어 있음에도 불구하고, 하나의 증발기(27)를 포함하는 냉동사이클에 의해 냉기의 열교환이 달성된다.First, FIG. 3 is a configuration diagram schematically showing a configuration of an independent cooling refrigerator according to the present invention. In the independent cooling refrigerator according to the present invention, a freezer compartment 1 and a refrigerating compartment 2 are partitioned with respect to a barrier 3. The cold air passage circulating the freezer compartment A and the cold air passage B circulating the refrigerating compartment are separated. At this time, although the freezing compartment side cold air flow path (A) and the refrigerating compartment side cold air flow path (B) are separated from each other, heat exchange of cold air is achieved by a refrigeration cycle including one evaporator 27.

이러한 냉동사이클은 저온/저압의 가스 냉매를 고온/고압의 가스 냉매로 승온/승압하는 압축기(21)와, 상기 압축기로부터 유입된 냉매를 외기에 의해 응축시키는 응축기(23)와, 다른 부분의 직경에 비해 협소한 직경으로 이루어져 상기 응축기로부터 유입된 냉매를 감압시키는 팽창밸브(25)와, 상기 팽창밸브를 통과한 냉매가 저압상태에서 증발됨에 따라 고내의 열을 흡수하는 증발기(27)로 구성된다. The refrigeration cycle includes a compressor 21 for raising / lowering a low / low pressure gas refrigerant to a high / high pressure gas refrigerant, a condenser 23 for condensing the refrigerant introduced from the compressor by outside air, and diameters of other parts. It is composed of an expansion valve (25) for reducing the refrigerant introduced from the condenser and the evaporator (27) absorbing heat in the refrigerator as the refrigerant passing through the expansion valve is evaporated in a low pressure state compared to the diameter of the .

이 때, 상기 증발기(27)가 냉동실측 냉기와 냉장실측 냉기를 모두 열교환시 키기 위해서, 냉동실측 냉기유로(A)와 냉장실측 냉기유로(B)에 공통 설치되어야 하며, 그 구체적인 형태는 후술하기로 한다.At this time, the evaporator 27 must be installed in common in the freezer compartment side cold air flow path (A) and the refrigerating compartment side cold air flow path (B) in order to heat exchange both the freezer compartment side cold and the cold compartment side cold air. Shall be.

한편, 냉동실(1)의 고내 온도가 냉장실(2)의 고내 온도보다 높기 때문에 하나의 증발기를 이용하여 냉동실측 냉기와 냉장실측 냉기가 각각 설정온도에 부합하는 온도로 열교환되기 위해서, 상기 증발기(27)를 중심으로 냉동실측 냉기와 냉장실측 냉기가 열교환되는 면적이 달라야 한다. 즉, 냉동실측 냉기가 열교환되는 증발기의 면적이 냉동실측 냉기가 열교환되는 증발기의 면적보다 커야 한다.On the other hand, since the internal temperature of the freezer compartment 1 is higher than the internal temperature of the refrigerating compartment 2, the evaporator 27 is used to exchange heat with the freezer compartment cold side and the refrigerating compartment side cold air at temperatures corresponding to the set temperatures using one evaporator. ), The area where the cold air in the freezer compartment and the cold air in the refrigerating compartment should exchange heat is different. That is, the area of the evaporator in which the freezer compartment cold air is heat-exchanged should be larger than the area of the evaporator in which the freezer compartment cold air is heat-exchanged.

이하, 상술한 바와 같은 독립냉각 냉장고가 구체적으로 구현된 실시예를 상세히 설명하면 다음과 같다.Hereinafter, an embodiment in which the independent cooling refrigerator as described above is specifically implemented will be described in detail.

먼저, 도 4는 본 발명의 실시예에 따른 독립냉각 냉장고의 구조를 나타낸 횡단면도이고, 도 5는 본 발명의 실시예에 따른 독립냉각 냉장고의 작용을 나타낸 정면도 및 측면도이다.First, Figure 4 is a cross-sectional view showing a structure of an independent cooling refrigerator according to an embodiment of the present invention, Figure 5 is a front view and a side view showing the operation of the independent cooling refrigerator according to an embodiment of the present invention.

도 4 및 5에 도시된 바에 따르면, 본 발명의 바람직한 실시예에 따른 독립냉각 냉장고는 배리어(3)를 중심으로 좌측에 냉동실(1)이 구비되고 우측에 냉장실(2)이 구비된다. 그리고 상기 냉동실(1)의 후면에 냉동실측 냉기가 열교환을 위해 순환하는 냉동실측 냉기덕트(100)가 구비되고, 상기 냉동실(1)의 후면과 냉장실(2)의 상부면에 걸쳐 냉장실측 냉기가 열교환을 위해 순환하는 냉장실측 냉기덕트(200)가 구비된다.4 and 5, the independent cooling refrigerator according to the preferred embodiment of the present invention is provided with a freezer compartment 1 on the left side and a refrigerating compartment 2 on the right side of the barrier 3.
