Description
본 발명은 냉장고에 관한 것으로, 더욱 상세하게는 냉장실과 냉동실을 독립적으로 냉각시킬 수 있도록 한 독립냉각방식 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to an independent cooling type refrigerator capable of independently cooling a refrigerator compartment and a freezer compartment.
일반적으로, 냉장고는 냉매(작동유체)가 압축 - 응축 - 팽창 - 증발하는 냉동사이클을 반복함에 따라 고내를 저온화시켜 음식물을 일정기간 동안 신선하게 유지시켜 주는 장치로서 생활에 있어서 필수품중 하나이다.In general, the refrigerator is one of the necessities of life as a device that keeps food fresh for a certain period of time by lowering the inside of the refrigerator as the refrigerant (working fluid) repeats the refrigeration cycle of compression, condensation, expansion and evaporation.
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 사이드 바이 사이드형 냉장고의 구조 및 작용를 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described the structure and operation of a typical side-by-side refrigerator.
먼저, 도 1에 도시된 바에 따르면, 상기 냉장고는 증발기(4)에 의해 열교환된 냉기중 대부분이 유입되어 약 -18℃의 고내 온도를 유지하고 있는 냉동실(1)과, 상기 증발기(4)에 의해 열교환된 냉기중 일부가 유입되어 약 0~7℃의 고내 온도를 유지하고 있는 냉장실로 크게 구분된다.First, as shown in FIG. 1, the refrigerator includes a freezer compartment 1 in which most of the cold air heat exchanged by the evaporator 4 is introduced to maintain an internal temperature of about −18 ° C., and the evaporator 4. Some of the heat exchanged by the cold air is introduced into the refrigerating chamber that maintains the internal temperature of about 0 ~ 7 ℃.
이 때, 냉동실(1)과 냉장실(2)은 배리어(3)에 의해 구획되며, 상기 배리어(3)의 후방 상부에는 증발기(4)에 의해 열교환된 냉기가 냉장실로 공급되도록 냉기 연통구(3a)가 구비되고, 상기 배리어(3)의 고내측 하부에는 상기냉장실(2)을 순환하여 고온화된 냉기가 다시 냉동실(1)로 유입되는 냉기 연통구(3b)가 각각 형성된다. 그리고 상기 냉기가 냉장실로 공급되도록 하는 냉기 연통구(3a) 내측에는 상기 냉장실(2)로 유입되는 냉기의 제어를 위한 댐퍼(미도시)가 구비된다.At this time, the freezer compartment 1 and the refrigerating compartment 2 are partitioned by a barrier 3, and the cold air communication port 3a is provided in the upper portion of the rear side of the barrier 3 so that the cold air heat exchanged by the evaporator 4 is supplied to the refrigerating compartment. And a cold air communication port 3b through which the high temperature cold air flows back into the freezing chamber 1 by circulating the refrigerating chamber 2. In addition, a damper (not shown) for controlling cold air flowing into the refrigerating compartment 2 is provided inside the cold air communication port 3a through which the cold air is supplied to the refrigerating compartment.
그리고, 도 2a에 도시된 바에 따르면, 상기 증발기(4)의 상부에는 증발기를 지나면서 저온화된 냉기를 냉동실(1)로 강제 순환시키는 송풍팬(6)과 상기 송풍팬을 구동하는 모터가 구비되며, 상기 증발기(4)의 전면에는 냉동실의 고내 공간과 상기 증발기(4)가 설치되는 공간을 구획하는 내측판(7)에 의해 냉기유로(10)가 형성된다. 그리고, 상기 내측판(7)에는 냉동실과 통하는 다수의 냉기 토출구(11)가 형성되고, 상기 내측판(7) 하부에는 냉동실을 순환하면서 고온화된 냉기가 다시 증발기(4)로 유입되는 냉기 흡입구(13)가 형성되며, 상기 냉동실(1)의 배면 아래에는 기계실(5)이 구비된다.And, as shown in Figure 2a, the 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 front surface of the evaporator (4) is formed with a cold air flow path (10) by the inner plate 7 for partitioning the interior space of the freezer compartment and the space in which the evaporator (4) 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 under the inner plate 7. 13 is formed, the machine chamber 5 is provided below the rear surface of 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.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.
따라서, 상기 증발기(4)를 통과하는 냉기는 증발기와의 열교환에 의해 저온화되며, 송풍팬(6)의 작동에 의해 냉동실측의 냉기유로(10)로 토출된다. 계속해서, 상기 냉기중 일부는 냉기 토출구(11)를 통해 냉동실(1)로 유입되고, 일부는 냉기 냉기 연통구(3a)를 통해 냉장실(2)로 유입된다. 이 후, 상기 냉동실(1) 및냉장실(2)을 순환하면서 고온화된 냉기는 다시 흡입구(13)를 통해 증발기(4)로 유입되어 열교환되는 냉기 순환구조를 이루게 된다.Therefore, the cold air passing through the evaporator 4 is lowered by heat exchange with the evaporator, and is discharged to the cold air passage 10 on the freezer compartment side by the operation of the blower fan 6. Subsequently, a part of the cold air flows into the freezing chamber 1 through the cold air discharge port 11, and a part of the cold air flows into the refrigerating chamber 2 through the cold air cold air communication port 3a. Thereafter, the cold air, which has become hot while circulating the freezing chamber 1 and the refrigerating chamber 2, is introduced into the evaporator 4 through the suction port 13 to form a cold air circulation structure in which heat is exchanged.
그러나, 이와 같은 종래의 냉장고는 냉동실측에만 증발기(4)가 구비되고, 상기 증발기(4)를 통해 열교환된 냉기가 냉동실측의 냉기유로(10) 상에서 일부 분배되어 냉장실(2)로 유입되는 구조여서 다음과 같은 문제점이 있었다.However, the conventional refrigerator has a structure in which the evaporator 4 is provided only at the freezing compartment side, and the cold air heat exchanged through the evaporator 4 is partially distributed on the cold air passage 10 at the freezing compartment side and flows into the refrigerating compartment 2. Therefore, there were the following problems.
먼저, 종래 구조의 냉장고에서는 냉동실(1) 혹은 냉장실(2) 어느 한쪽 고내의 온도만 만족되지 못하더라도 만족하지 못하는 고내의 온도를 낮추기 위해 압축기 및 송풍팬이 작동해야 하므로 불필요한 전력의 소비가 야기되는 문제점이 있었다.First, in the refrigerator having a conventional structure, the compressor and the blower fan must be operated to lower the temperature in the refrigerator, which is not satisfied even if the temperature in either the freezer compartment 1 or the refrigerator compartment 2 is not satisfied, causing unnecessary power consumption. There was a problem.
예를 들어, 냉동실(1)의 온도가 만족되더라도 냉장실(2)의 온도가 만족되지 않은 경우에는 냉장실의 온도를 만족시키기 위해 압축기 및 송풍팬을 작동시켜 냉장실의 온도를 낮추어야 하는데, 이때 냉기는 고내 온도가 이미 만족된 냉동실(1)로도 공급되므로 불필요한 냉기 공급이 이루어지는 셈이며, 이는 소비전력을 불필요하게 소모하는 결과를 낳게 된다.For example, even when the temperature of the freezer compartment 1 is satisfied, if the temperature of the refrigerator compartment 2 is not satisfied, the temperature of the refrigerator compartment should be lowered by operating a compressor and a blower fan to satisfy the temperature of the refrigerator compartment. Since the temperature is also supplied to the freezer compartment 1, which is already satisfied, unnecessary cold air is supplied, which results in unnecessary consumption of power consumption.
다음으로, 종래 구조의 냉장고는 증발기(4)를 통과한 후 냉장실(2)로 분배되는 냉기의 양이 적어 상대적으로 냉동실(1)에 비해 냉각 속도가 떨어지는 문제점이 있었다.Next, the refrigerator having a conventional structure has a problem that the cooling rate is relatively lower than that of the freezing chamber 1 because the amount of cold air distributed to the refrigerating chamber 2 after passing through the evaporator 4 is small.
즉, 비록 냉장실(2)의 설정온도가 냉동실(1)에 비해 고온이라 할지라도 냉기의 풍량이 적음으로 인해 냉장실에 대한 냉각 속도가 떨어지기 마련이다.That is, even though the set temperature of the refrigerating compartment 2 is higher than that of the freezing compartment 1, the cooling rate of the refrigerating compartment is lowered due to the small amount of air flow.
이와 더불어, 종래 구조의 냉장고는 냉동실(1) 뒤쪽벽에 설치된 증발기(4)의두께로 인해 냉동실의 고내 용적이 줄어들어, 공간 사용이 비효율적으로 이루어지는 단점이 있었다.In addition, the refrigerator having the conventional structure has a disadvantage in that the high volume of the freezer compartment is reduced due to the thickness of the evaporator 4 installed on the rear wall of the freezer compartment 1, resulting in inefficient use of space.
본 발명은 상기 문제점을 해결하기 위해 안출된 것으로, 냉동실과 냉장실을 각각 독립적으로 냉각시킬 수 있도록 하여 냉각효율 향상 및 소비전력 감소를 도모하는 한편 기존 냉장고에서 냉장실에 비해 상대적으로 냉각속도가 늦었던 냉장실의 냉각속도를 향상시킬 수 있도록 한 냉장고를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, by allowing each of the freezer compartment and the refrigerating compartment to be independently cooled to improve the cooling efficiency and to reduce the power consumption, while the refrigerating compartment was relatively slow compared to the refrigerator compartment in the conventional refrigerator The purpose is to provide a refrigerator to improve the cooling rate of the.
본 발명의 또 다른 목적은, 상기한 목적들을 달성함과 더불어 냉장고의 고내 용적을 극대화할 수 있도록 한 냉장고를 제공하는 것이다.Still another object of the present invention is to provide a refrigerator capable of maximizing the high volume of the refrigerator while achieving the above objects.

도 3 및 도 4에 도시된 바에 따르면, 본 발명의 제1실시예에 따른 독립냉각 방식의 냉장고는 배리어(3)를 중심으로 좌측에 냉동실(1)이 구비되고 우측에 냉장실(2)이 구비되며, 배리어(3) 내부에는 냉동실측으로 냉기를 공급 및 순환시키기 위한 냉동실용 냉기유로(A)와 냉장실측으로 냉기를 공급 및 순환시키기 위한 냉장실용 냉기유로(B)가 구비된다.3 and 4, the independent cooling refrigerator according to the first embodiment of the present invention includes a freezer compartment 1 on the left side and a freezer compartment 2 on the right side of the barrier 3.

한편, 배리어(3)에는 분리판(9)에 의해 분리되어 증발기(4)를 통과한 냉기를 냉동실(1)과 냉장실(2)로 송풍시키기 위한 송풍팬(105)(205)이 냉동실용 냉기유로(A)와 냉장실용 냉기유로(B)에 각각 설치되는 바, 상기 송풍팬(105)(205)으로는 원심팬인 시로코팬을 적용함이 바람직하다. 상기와 같이 송풍팬으로서 원심팬인 시로코팬을 적용하는 이유는 배리어(3)의 좁은 폭을 고려한 때문이다.On the other hand, in the barrier 3, blower fans 105 and 205 for blowing cold air, which are separated by the separating plate 9 and passed through the evaporator 4, to the freezing chamber 1 and the refrigerating chamber 2, are provided for the freezing chamber cold air. Bars are provided in the flow path (A) and the cold air flow path (B) for the refrigerating chamber, respectively, and it is preferable to apply a sirocco fan, which is a centrifugal fan, to the blowing fans 105 and 205. The reason why the sirocco fan, which is a centrifugal fan, is used as the blowing fan as described above is that the narrow width of the barrier 3 is considered.
따라서, 냉동실측 냉기는 배리어(3) 하부에 형성된 냉기 흡입구(103)를 통해 증발기(4)의 냉동실측 열교환영역으로 유입되어 열교환된 다음 냉동실측 냉기유로(A)를 통해 유동하여 배리어(3) 후방 상부측의 냉기 토출구(100)을 통해 나와, 냉동실측 칸막이(7)에 높이 방향을 따라 형성된 냉기 토출구(101)들을 통해 냉동실(1)로 토출된다.Therefore, the freezer compartment cold air flows into the freezer compartment side heat exchange area of the evaporator 4 through the cold air inlet 103 formed under the barrier 3 and is heat exchanged, and then flows through the freezer compartment side cold air flow path A to allow the barrier 3 to flow. It exits through the cold air discharge port 100 of the rear upper side, and is discharged to the freezer compartment 1 through the cold air discharge port 101 formed along the height direction in the freezer compartment side partition 7.
그리고, 냉장실(2)의 냉기는 배리어(3) 하부에 형성된 냉기 흡입구(203)를 통해 증발기(4)의 냉장실측 열교환영역으로 유입되어 열교환된 다음 배리어(3) 상부에 형성된 냉기 토출구를 통해 냉장실(2)로 토출된다.In addition, the cold air of the refrigerating compartment 2 flows into the refrigerating compartment side heat exchange area of the evaporator 4 through the cold air inlet 203 formed under the barrier 3 and is heat-exchanged, and then refrigerates through the cold air outlet formed on the barrier 3. It is discharged to (2).
즉, 도 5를 참조하면, 본 발명의 냉장고는 배리어(3)에 설치된 증발기가 분리판(9)을 중심으로 열교환 면적 및 냉동실(1)로 공급되는 냉기유로(A)와 냉장실(2)로 공급되는 냉기유로(B)가 양분된다.That is, referring to FIG. 5, the refrigerator of the present invention includes the evaporator installed in the barrier 3 to the cold air flow path A and the refrigerating chamber 2, which are supplied to the heat exchange area and the freezing chamber 1 around the separator 9. The cold air flow path B supplied is bisected.
그리고, 상기 냉동실용 냉기유로(A)와 냉장실용 냉기유로(B)가 서로 연결되고, 서로 연결된 유로(C)상에 댐퍼(8)가 설치되어 있으므로, 어느 한쪽 고내의 온도가 만족될 경우 만족된 쪽의 송풍팬을 오프시킨 상태에서 상기 댐퍼(8)를 열어 냉기를 고내 온도가 만족되지 못한 쪽으로 집중시킴으로써 만족못한 고내의 온도를 빠른 시간내에 만족시킬 수 있게 된다.The freezer compartment cold air flow path A and the refrigerating compartment cold air flow path B are connected to each other, and a damper 8 is provided on the flow path C connected to each other. By opening the damper 8 in the state in which the blowing fan is turned off, the cold air is concentrated toward the unsatisfactory temperature of the refrigerator so that the unsatisfactory temperature can be satisfied in a short time.
상기와 같이 구성된 본 발명의 독립냉각 방식 냉장고의 동작과정은 다음과 같다.Operation of the independent cooling method refrigerator of the present invention configured as described above is as follows.
먼저, 압축기(30)의 운전으로 증발기(4)에 열교환 환경이 조성되면, 배리어(3) 내부의 냉동실용 냉기유로(A)상에 설치된 냉동실용 송풍팬(105)과 냉장실용 송풍팬(205)이 각각 각각 고내의 냉기를 강제 순환시키게 된다. 이 때, 냉동실(1)을 순환하는 냉기는 냉기 흡입구(103)를 통해 유입되어 분리판(9)에 의해 분리된 증발기(4)의 일측 영역을 지나면서 열교환된 다음 배리어(3) 후방 상부측의 냉기 토출구(100)을 통해 나온 후, 계속해서 유동하여 냉동실측 칸막이(7)에 높이 방향을 따라 일정 간격 이격 형성된 각 냉기 토출구(101)를 통해 냉동실(1)로 토출되는 순환과정을 반복하게 된다.First, when the heat exchange environment is formed in the evaporator 4 by the operation of the compressor 30, the freezing chamber blowing fan 105 and the refrigerating chamber blowing fan 205 installed on the freezing chamber cold air flow path A inside the barrier 3. Each will force the cold air in the oven. At this time, the cold air circulating through the freezer compartment 1 flows through the cold air inlet 103 and passes through one region of the evaporator 4 separated by the separating plate 9, and then the upper side behind the barrier 3. After exiting through the cold air outlet 100 of the, it continues to flow and repeat the circulation process discharged to the freezer compartment (1) through each cold air outlet 101 formed at regular intervals along the height direction in the freezer compartment partition (7) do.
그리고 냉장실(2)을 순환하는 냉기는 배리어(3)에 형성된 냉기 흡입구(203)를 통해 유입되어 분리판(9)에 의해 분리된 증발기(4)의 타측 영역을 지나면서 열교환된다. 이렇게 열교환된 냉기는 배리어(3)의 냉장실측에 위치한 냉기 토출구(201)를 통해 냉장실(2)로 토출되는 순환과정을 반복하게 된다.The cold air circulating in the refrigerating compartment 2 flows through the cold air inlet 203 formed in the barrier 3 and passes through the other region of the evaporator 4 separated by the separator 9. The cold air heat-exchanged in this way repeats the circulation process discharged to the refrigerating chamber 2 through the cold air discharge port 201 located in the refrigerating chamber side of the barrier (3).
한편, 상기 냉동실용 냉기유로(A)와 냉장실용 냉기유로(B)가 서로 연결되고, 서로 연결된 유로(C)상에는 댐퍼(8)가 설치됨에 따라, 어느 한쪽 고내의 온도가 먼저 만족된 경우 상기 댐퍼(8)를 열어 온도가 만족된 고내측 증발기를 지난 냉기를 고내 온도가 만족되지 못한 쪽으로 보냄으로써, 한쪽으로 냉기를 집중시켜 만족못한 고내의 온도를 빠른 시간내에 만족시킬 수 있게 된다.On the other hand, as the freezer compartment cold air flow path (A) and the refrigerating compartment cold air flow path (B) is connected to each other, and the damper (8) is installed on the flow path (C) connected to each other, the temperature in any one of the refrigerator is satisfied first By opening the damper 8 and sending the cold air past the high internal evaporator whose temperature is satisfied to the temperature where the internal temperature is not satisfied, it is possible to concentrate the cold air to one side to satisfy the unsatisfactory internal temperature in a short time.
이 때, 온도가 만족된 고내측 송풍팬은 작동하지 않아도 되므로 소비전력을 줄일 수 있게 된다.At this time, since the high inner blower fan having a satisfactory temperature does not need to operate, power consumption can be reduced.
따라서, 본 발명에 따른 독립냉각 냉장고는 증발기(4)의 열교환면적을 2분하여 냉기를 분리시키고, 각 냉기유로(A)(B)에 독립적으로 제어되는 송풍팬(105)(205)을 설치하여 냉동실(1)과 냉장실(2)을 독립적으로 냉각시킴에 따라, 냉각효율 향상 및 소비전력 감소를 도모할 수 있다. 그리고, 이와 더불어 기존 냉장고에서 냉동실(1)에 비해 상대적으로 냉각속도가 늦었던 냉장실(2)의 냉각속도를 향상시킬 수 있으며, 냉장고의 내용적을 극대화할 수 있게 된다.Therefore, the independent cooling refrigerator according to the present invention separates the cold air by dividing the heat exchange area of the evaporator 4 into two minutes, and installs blower fans 105 and 205 independently controlled in each cold air flow path (A) and (B). By cooling the freezer compartment 1 and the refrigerating compartment 2 independently, the cooling efficiency can be improved and the power consumption can be reduced. In addition, it is possible to improve the cooling rate of the refrigerating compartment 2, which has a relatively low cooling rate compared to the freezer compartment 1 in the existing refrigerator, and maximize the contents of the refrigerator.
즉, 종래 구조의 냉장고에서는 냉동실(1) 혹은 냉장실(2) 어느 한쪽 고내의 온도만 만족되지 못하더라도 만족하지 못하는 고내의 온도를 낮추기 위해 압축기 및 송풍팬이 작동해야 하므로 불필요한 전력의 소비가 야기되는 문제점이 있었으나, 본 발명의 냉장고는 냉동실(1)과 냉장실(2)을 독립적으로 냉각시키며 어느 한쪽이 먼저 만족시 온도가 만족된 고내측 송풍팬은 오프시킨 상태에서 댐퍼(8)를 동작시켜 만족된 고내측 냉기를 고내 온도가 만족되지 못한 쪽으로 집중시킬 수 있음에 따라, 불필요한 전력의 소비를 줄일 수 있게 된다.That is, in the refrigerator having a conventional structure, the compressor and the blower fan should be operated to lower the temperature in the refrigerator that is not satisfied even if the temperature in either the freezer compartment 1 or the refrigerator compartment 2 is not satisfied, causing unnecessary power consumption. There was a problem, but the refrigerator of the present invention independently cools the freezing compartment 1 and the refrigerating compartment 2, and when one of the first satisfactory conditions is satisfied, the damper 8 is operated by turning off the high-side blower fan whose temperature is satisfied. As the internal high temperature cold air can be concentrated toward the unsatisfactory internal temperature, unnecessary power consumption can be reduced.
또한, 본 발명의 냉장고는 냉동실(1)과 냉장실(2)을 독립적으로 냉각시킴으로 인해, 종래에 증발기를 통과한 후 냉장실(2)로 분배되는 냉기의 양이 적어 상대적으로 냉동실(1)에 비해 냉각속도가 떨어지는 문제점이 해소된다.In addition, since the refrigerator of the present invention independently cools the freezing compartment 1 and the refrigerating compartment 2, the amount of cold air distributed to the refrigerating compartment 2 after passing through an evaporator in the related art is relatively lower than that of the freezer compartment 1. The problem of low cooling rate is solved.
이와 더불어, 본 발명의 냉장고는 배리어(3)에 증발기(4)가 설치됨을 인해 냉동실측에 설치되던 종래와는 달리 냉동실(1)의 고내 용적을 극대화할 수 있게 된다. 즉, 본 발명에 따르면, 기존의 냉동실측에 설치되던 증발기를 삭제하는 대신, 냉장고의 배리어(3) 부분에 증발기(4)를 설치함으로써, 냉장실(2)의 내용적에 손실을 입히지 않고 냉동실의 내용적을 극대화 할 수 있게 된다.In addition, the refrigerator of the present invention can maximize the internal volume of the freezer compartment 1 unlike the conventional one installed on the freezer compartment side due to the evaporator 4 installed on the barrier 3. That is, according to the present invention, instead of deleting the existing evaporator installed on the freezer compartment side, by installing the evaporator 4 in the barrier 3 portion of the refrigerator, the contents of the freezer compartment without damaging the contents of the refrigerating compartment 2. You can maximize your enemies.
그리고, 본 발명에 의하면 냉동실(1)과 냉장실(2)을 순환하는 냉기유로를 각각 별도로 분리시킬 수 있음에 따라, 냉동실(1)과 냉장실(2)에 수납되는 음식물의 냄새가 서로 간섭하는 것을 방지할 수도 있다.In addition, according to the present invention, since the cold air passages circulating in the freezing compartment 1 and the refrigerating compartment 2 can be separately separated, the smells of foods stored in the freezing compartment 1 and the refrigerating compartment 2 interfere with each other. It can also be prevented.
한편, 냉동실로부터 유입되는 냉기와 냉장실로부터 유입되는 냉기가 증발기 입구측에서 만나지 않음에 따라 온도차로 인해 서리가 쉽게 생성되는 현상이 방지됨으로써 제상 주기가 늘어나게 된다.On the other hand, since the cold flow from the freezer compartment and the cold air flow from the refrigerating compartment do not meet at the inlet side of the evaporator, a phenomenon in which frost is easily generated due to the temperature difference is prevented, thereby increasing the defrost cycle.
요컨대, 본 발명의 독립냉각 방식의 냉장고는 배리어에 1개의 증발기와 2개의 팬을 설치하고 냉기유로를 분리함으로써 냉동실측 냉기와 냉장실측 냉기가 서로 독립된 순환구조를 갖도록 함은 물론, 냉기를 어느 한쪽 고내로 집중시킬 수 있어 소비전력을 감소시킬 수 있으며, 냉동실측에 증발기가 설치되던 기존 구조와는 달리 냉동실(1)의 고내 용적을 극대화할 수 있게 된다.In other words, the refrigerator of the independent cooling method of the present invention by installing one evaporator and two fans in the barrier and separating the cold air flow path to ensure that the freezer compartment cold side and the cold compartment side cold air have independent circulation structure, as well as the cold air to either side It can be concentrated in the interior can reduce the power consumption, unlike the existing structure in which the evaporator is installed in the freezer compartment can maximize the interior volume of the freezer (1).

Can be reduced.
둘째, 본 발명에 의하면 냉장실로의 냉기 강제 공급을 위한 송풍팬이 구비됨으로써, 냉장실로 유입되는 냉기 풍량을 증가시킬 수 있어 냉장실에 대한 냉각 속도를 향상시킬 수 있게 된다.Second, according to the present invention is provided with a blower fan for forced supply of cold air to the refrigerating compartment, it is possible to increase the amount of cold air flowing into the refrigerating compartment can improve the cooling rate for the refrigerating compartment.
셋째, 본 발명의 냉장고는 냉동실과 냉장실을 구획하는 배리어에 증발기가 설치됨으로 인해 냉동실의 고내 용적을 극대화 할 수 있게 된다.Third, the refrigerator of the present invention can maximize the high volume of the freezer compartment because the evaporator is installed in the barrier partitioning the freezer compartment and the refrigerating compartment.
한편, 본 발명의 냉장고는 냉동실로부터 유입되는 냉기와 냉장실로부터 유입되는 냉기가 증발기 입구측에서 만나지 않음에 따라 서리가 쉽게 발생하지 않아 제상주기가 늘어나게 되는 효과가 있다.On the other hand, the refrigerator of the present invention has an effect that the defrost cycle is increased because frost does not easily occur since the cold flow from the freezer compartment and the cold air flow from the refrigerating chamber do not meet at the inlet side of the evaporator.
