Description
본 발명은 음식물을 장기간 신선하게 보관하기 위하여 상기한 음식물에 냉기를 공급하는 냉장고에 관한 것으로서, 특히 냉장실 냉기가 저온다습한 상태에서 저온저습한 상태로 변화된 후 냉동실 냉기와 서로 혼합되어 증발기로 제공되는 구조를 구비한 냉장고용 냉기흡입덕트의 구조에 관한 것이다.The present invention relates to a refrigerator for supplying cold air to the food in order to keep food fresh for a long time, and in particular, the refrigerator compartment is changed into a low temperature and low temperature state in a low temperature and high humidity state and then mixed with a freezer compartment cold air to provide an evaporator. It relates to a structure of a cold air suction duct for a refrigerator having a structure.
도 1은 종래 기술에 따른 냉장고용 냉기흡입덕트의 구조가 도시된 냉장고의 측단면도로서, 이를 참조하여 종래 기술에 따른 냉장고의 구조 및 작동을 설명하면 다음과 같다.1 is a side cross-sectional view of a refrigerator in which a structure of a cold air suction duct for a refrigerator according to the prior art is illustrated. Referring to this, the structure and operation of the refrigerator according to the prior art will be described below.
먼저, 냉장고 하단의 기계실(1)에 설치되어 있는 압축기에 의해 냉매가 압축되어 고온고압의 증기상태로 변화된다.First, the refrigerant is compressed by a compressor installed in the machine room 1 at the bottom of the refrigerator to change into a high temperature, high pressure steam state.
이후, 상기 압축기를 통해 압축된 냉매가 압축기에 함께 기계실(1)에 설치된 응축기로 흡입되면 상기 응축기는 외부 공기와의 열교환을 통해 냉매의 열을 방출하여 상기한 냉매를 상온고압의 액상태로 변화시킨다.Thereafter, when the refrigerant compressed by the compressor is sucked into the condenser installed in the machine room 1 together with the compressor, the condenser releases heat of the refrigerant through heat exchange with external air to change the refrigerant into a liquid state at room temperature and high pressure. Let's do it.
이후, 상기 응축기에 의해 응축된 냉매는 모세관을 지나면서 그중 일부가 감압됨으로써 액체와 기체가 혼합된 2상 상태가 된다.Subsequently, the refrigerant condensed by the condenser passes through a capillary tube, whereby some of the refrigerant is decompressed to be in a two-phase state in which liquid and gas are mixed.
이후, 상기 모세관을 통과하여 냉동실의 후측에 설치된 증발기(3)로 흡입된냉매는 완전히 기화되면서 주위의 열을 빼앗아 주변을 냉각시키게 되고, 이렇게 상기 증발기(3)에 의해서 냉각된 공기가 냉동실과 냉장실로 각각 제공된다.Thereafter, the refrigerant sucked into the evaporator 3 installed at the rear side of the freezing chamber through the capillary tube is completely vaporized to take heat away from the surroundings, thereby cooling the surroundings. Thus, the air cooled by the evaporator 3 is stored in the freezer compartment and the refrigerating compartment. Are each provided.
이때, 상기 응축기에는 냉매의 방열 작용을 돕기 위한 방열팬이 설치되고, 상기 증발기(3)에는 냉매의 흡열 작용을 돕기 위한 흡열팬(5)이 설치되어 있다.At this time, the heat dissipation fan is installed in the condenser to help the heat dissipation action of the refrigerant, and the endothermic fan 5 is installed in the evaporator 3 to help the heat dissipation action of the refrigerant.
이후, 상기한 냉동실과 냉장실을 순환하여 온도가 상승된 각각의 냉기는 냉동실과 냉장실 사이에 설치된 냉기흡입덕트(7)를 통하여 증발기(3)로 제공되고, 이렇게 상기 증발기(3)로 제공된 냉기는 냉매와의 열교환을 통해 다시 냉각되어 상기한 냉동실과 냉장실로 각각 제공된다.Thereafter, each of the cold air whose temperature is elevated by circulating the freezer compartment and the refrigerating compartment is provided to the evaporator 3 through a cold air suction duct 7 installed between the freezer compartment and the refrigerating compartment, and the cold air provided to the evaporator 3 is thus provided. It is cooled again through heat exchange with the refrigerant and provided to the freezing compartment and the refrigerating compartment, respectively.
이와 동시에, 상기 증발기(3)를 통과한 고온저압의 냉매는 다시 상기 압축기로 유입된다.At the same time, the high temperature low pressure refrigerant passing through the evaporator 3 flows back into the compressor.
여기서, 상기한 냉기흡입덕트(7)는 도 2에 도시된 바와 같이, 냉장실 냉기가 흡입되는 중간통로(7a)와, 상기 중간통로(7a)의 좌우 양측에 형성되어 냉동실 냉기가 흡입되는 좌측 및 우측통로(7b, 7c)로 이루어져 있다.Here, the cold air suction duct (7) is shown in Figure 2, the intermediate passage (7a) that the cold compartment cold air is sucked, the left and right sides of the intermediate passage (7a) formed on the left and It consists of right passages 7b and 7c.
따라서, 상기한 냉동실 냉기와 냉장실 냉기는 서로 섞이지 않은 상태 그대로 상기 냉기흡입덕트(7)를 통해 증발기(3)의 하측으로 제공되게 된다. 즉, 상기한 냉장실 냉기는 상기 중간통로(7a)를 통하여 증발기(3)의 중간 부분으로 제공되고, 상기한 냉동실 냉기는 상기 좌측 및 우측통로(7b, 7c)를 통하여 증발기(3)의 양측 부분으로 제공된다.Therefore, the freezer compartment cold and the cold compartment cold air are provided to the lower side of the evaporator 3 through the cold air suction duct 7 without being mixed with each other. That is, the refrigerating compartment cold air is provided to the middle portion of the evaporator 3 through the intermediate passage 7a, and the freezer compartment cold air is provided at both sides of the evaporator 3 through the left and right passages 7b and 7c. Is provided.
그런데, 상기한 냉동실 냉기가 저온저습 상태인 것과는 반대로, 상기한 냉장실 냉기는 저온다습한 상태이기 때문에 상기 증발기(3)의 표면에 착상현상을 발생시킨다. 이때, 상기 증발기(3)의 착상현상은 냉장실 냉기가 통과하는 중간 부분에 국부적으로 발생되며, 특히 상기 증발기(3)의 하단부에 더 폭넓게 분포된다. 상기한 증발기(3)의 착상영역은 도 3의 '(가)' 부분으로 표시할 수 있다.However, in contrast to the freezer compartment cold air having a low temperature and low humidity state, since the cold compartment cold air is a low temperature and high humidity state, the phenomenon occurs in the surface of the evaporator (3). At this time, the phenomena of the evaporator 3 are locally generated in the middle part through which the refrigerating chamber cold air passes, and are more widely distributed at the lower end of the evaporator 3. The implantation region of the evaporator 3 may be indicated by a part (a) of FIG. 3.
이와 같이 상기 증발기(3)에 국부적인 착상현상이 발생되면 상기한 착상현상이 일어난 증발기(3)의 중간 부분에 큰 유동저항이 생길 뿐만 아니라 상기 증발기(3)의 전체적인 열전달 성능이 저하되어 냉장고의 냉각 성능이 떨어지게 된다.As such, when localized phenomena occur in the evaporator 3, not only large flow resistance is generated in the middle portion of the evaporator 3 in which the above-mentioned phenomena occur, but the overall heat transfer performance of the evaporator 3 is lowered, Cooling performance will be reduced.
요약하면, 종래 기술에 따른 냉기흡입덕트의 구조는 냉동실 냉기와 냉장실 냉기가 서로 혼합되지 않은 상태로 증발기(3)에 제공되기 때문에 저온다습한 냉장실 냉기가 그대로 상기 증발기(3)를 향해 제공되어 증발기(3)에 국부적인 착상현상이 발생되고, 이로 인하여 상기 증발기(3)에 의한 냉매와 냉기의 효율적인 열교환이 불가능하게 되어 냉장고의 냉각 성능이 저하되는 문제점이 있었다.In summary, since the structure of the cold air suction duct according to the prior art is provided to the evaporator 3 in a state where the freezer cold and the cold compartment cold air are not mixed with each other, the cold and cold refrigerator compartment cold air is provided toward the evaporator 3 as it is. The local phenomena occur in (3), which makes it impossible to efficiently exchange heat between the refrigerant and the cold air by the evaporator 3, thereby lowering the cooling performance of the refrigerator.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 냉장실 냉기가 저온다습한 상태에서 저온저습한 상태로 변화된 후 냉동실 냉기와 서로 혼합되어 증발기로 제공되는 구조를 구비함으로써 상기한 냉장실 냉기로 인한 증발기의 착상현상이 방지되어 상기 증발기의 열교환 효율이 높아지고 냉장고의 냉각 성능이 향상되도록 하는 냉장고용 냉기흡입덕트의 구조를 제공하는데 그 목적이 있다.The present invention has been made in order to solve the above problems, the refrigerator compartment cold air is changed to a low temperature and low temperature state in the low temperature and high humidity state and then having a structure that is mixed with the freezer compartment cold and provided to the evaporator as described above It is an object of the present invention to provide a structure of a cold air suction duct for a refrigerator that prevents the phenomenon of the evaporator to increase the heat exchange efficiency of the evaporator and improve the cooling performance of the refrigerator.
