본 발명은 냉장고의 냉장실용 냉기 유로 장치에 관한 것으로서, 특히 냉장실로 공급된 냉기가 상기 냉장실 내부의 구석구석까지 신속하게 골고루 제공될 수 있는 구조를 구비한 냉장고의 냉장실용 냉기 유로 장치에 관한 것이다.The present invention relates to a cold air flow path device for a refrigerator compartment of a refrigerator, and more particularly, to a cold air flow path device for a refrigerator compartment having a structure in which cold air supplied to the refrigerator compartment can be quickly and evenly provided to every corner of the inside of the refrigerator compartment.
일반적인 가정용 냉장고에서 음식물을 신선한 상태로 장기간 보관하기 위해서는 냉동실과 냉장실의 고내온도를 균일하게 유지시키는 것이 필수적이므로, 이를 위해 냉장고의 측벽이나 도어 측에 냉기토출구를 형성시켜 냉기유로를 변경시키는 방식을 사용하고 있다.In order to keep food in a fresh state for a long time, it is essential to maintain the inside temperature of the freezer compartment and the refrigerating compartment uniformly. For this purpose, a cold air outlet is formed on the side wall or door of the refrigerator to change the cold air flow path. Doing.
도 1은 종래 기술에 따른 냉장고의 내부 구조가 개략적으로 도시된 정면도이고, 도 2는 종래 기술에 따른 냉장고의 내부 구조가 도시된 측단면도이다.1 is a front view schematically showing the internal structure of the refrigerator according to the prior art, Figure 2 is a side cross-sectional view showing the internal structure of the refrigerator according to the prior art.
상기한 도 1 및 도 2를 참조하면, 종래 기술에 따른 냉장고는 압축기, 응축기, 모세관, 증발기(1)를 포함한 냉동시스템을 구비하여 상기 증발기(1)를 통해 제공된 냉기를 냉동실(F)과 냉장실(R)로 각각 분배하도록 구성되어 있다.1 and 2, the refrigerator according to the related art has a refrigeration system including a compressor, a condenser, a capillary tube, and an evaporator 1, and provides the cold air provided through the evaporator 1 to the freezer compartment F and the refrigerating compartment. It is comprised so that each may distribute to (R).
더 상세하게 설명하면, 냉장고의 기계실에 설치된 압축기와 응축기 및 모세관을 차례로 거치면서 액체와 기체가 혼합되어 있는 2상 상태가 된 냉매는 냉동실(F) 후측에 설치된 증발기(1)로 흡입된 후 상기 증발기(1)를 통과하면서 완전히 기화되어 주위의 열을 빼앗게 된다.In more detail, the refrigerant in a two-phase state in which liquid and gas are mixed while passing through a compressor, a condenser, and a capillary tube installed in the machine room of the refrigerator is sucked into the evaporator 1 installed at the rear side of the freezer compartment F, and then As it passes through the evaporator 1, it is completely vaporized to take heat away from the surroundings.
상기와 같은 냉매의 증발 작용에 의해 증발기(1) 주변의 공기는 냉각되게 되고, 이렇게 냉각된 냉기는 냉동실팬(3)에 의해 송풍되어 쉬라우드(5)와 팬그릴(7)로 둘러싸인 냉기실(C)로 이동된다.The air around the evaporator 1 is cooled by the evaporation action of the refrigerant as described above, and the cooled cold air is blown by the freezer compartment fan 3 and surrounded by the shroud 5 and the fan grill 7. Moved to (C).
이후, 상기 냉기실(C)로 이동된 냉기는 팬그릴(7)을 통과하여 냉동실(F)로 공급되는 동시에 냉장실(R)의 배면에 설치된 멀티토출덕트(9)로 이동되어 상기 멀티토출덕트(9)에 형성된 복수개의 냉기토출구(9a)(9b)(9c)를 통해 냉장실(R)로 공급되게 된다.Thereafter, the cold air moved to the cold air chamber C is supplied to the freezing chamber F through the fan grill 7 and moved to the multi discharge duct 9 installed on the rear surface of the refrigerating chamber R, thereby transferring the multi discharge duct. Through the plurality of cold air discharge ports 9a, 9b, 9c formed in (9), it is supplied to the refrigerating chamber (R).
상기와 같이 냉동실(F)과 냉장실(R)로 각각 공급된 냉기는 상기 냉동실(F)과 냉장실(R)을 순환한 다음 배리어(11)에 형성된 냉기흡입유로(11a)를 통해 흡입되어 상기 증발기(1) 측으로 이동된다.As described above, the cold air supplied to the freezing compartment F and the refrigerating compartment R is circulated through the freezing compartment F and the refrigerating compartment R, and is then sucked through the cold air suction passage 11a formed in the barrier 11 to the evaporator. It is moved to (1) side.
이때, 상기 냉동실(F)과 냉장실(R)에는 각각 고내온도를 감지하는 냉동실센서(13)와 냉장실센서(15)(16)가 설치되어 있으며, 이러한 각 냉동실센서(13) 및 냉장실센서(15)(16)의 감지결과에 따라 압축기의 온/오프가 결정되어 냉동시스템이 동작되게 된다.In this case, the freezer compartment F and the refrigerating compartment R are respectively provided with a freezer compartment sensor 13 and a refrigerating compartment sensor 15, 16 for sensing a temperature inside the refrigerator, and each freezer compartment sensor 13 and a refrigerator compartment sensor 15. The on / off of the compressor is determined according to the detection result of 16), and the refrigeration system is operated.
즉, 상기 압축기는 냉동실(F)과 냉장실(R)의 고내온도가 일정한 범위로 유지되도록 상기 냉동실센서(13)와 냉장실센서(15)(16)에 의해서 감지된 냉동실(F)과 냉장실(R)의 내부온도의 높고 낮음에 따라 작동된다.That is, the compressor includes the freezer compartment F and the refrigerator compartment R detected by the freezer compartment sensor 13 and the refrigerator compartment sensor 15, 16 so that the internal temperatures of the freezer compartment F and the refrigerator compartment R are maintained in a predetermined range. It operates according to the high and low of the internal temperature.
그런데, 상기와 같은 종래의 냉장고는 냉장실(R)의 냉기 유로 구조가 배면의 멀티토출덕트(9)에서 냉기가 공급된 후 상측의 배리어(11)에 형성된 냉기흡입유로(11a)를 통해 흡입되도록 되어 있기 때문에 상기 멀티토출덕트(9)의 냉기토출구(9a)(9b)(9c) 근처에 있는 식품은 냉기의 영향을 많이 받아 과냉되고 냉장실도어(17) 근처에 있는 식품, 특히 도어바스켓(19)에 보관된 식품은 상대적으로 냉기의 영향을 받지 못하게 되어 약냉되는 현상이 발생된다.However, in the conventional refrigerator as described above, the cold air flow path structure of the refrigerating chamber R is sucked through the cold air suction flow path 11a formed in the upper barrier 11 after cold air is supplied from the rear multi discharge duct 9. Since the foods near the cold air discharge ports 9a, 9b, and 9c of the multi-discharge duct 9 are affected by cold air, the foods near the refrigerating chamber door 17, in particular, the door basket 19 ) Foods stored in) are relatively unaffected by cold, causing mild cooling.
즉, 상기한 종래 기술에 따른 냉장고는 냉장실(R)의 내부온도가 멀티토출덕트(9)의 냉기토출구(9a)(9b)(9c)로부터의 거리에 따라 그 편차가 심하게 나타나 상기 냉장실(R)의 고내온도 분포가 매우 불균일한 문제점이 있었다.That is, in the refrigerator according to the related art, the temperature of the refrigerating chamber R is severely varied depending on the distance from the cold air discharge ports 9a, 9b, 9c of the multi-discharge duct 9. There was a problem that the distribution of high temperature inside of the very uneven.
또한, 종래의 냉장고는 냉장실도어(17)를 자주 개폐하는 여름철의 경우, 상기 냉장실도어(17)의 개폐에 따른 온도상승에 신속히 대응하기 어려운 구조이기 때문에 식품이 손상되기 쉬운 문제점이 있었다.In addition, the conventional refrigerator has a problem that food is easily damaged because it is difficult to quickly respond to the temperature rise due to the opening and closing of the refrigerating chamber door 17 in the summer when the refrigerating chamber door 17 is frequently opened and closed.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 냉장실로 공급된 냉기가 상기 냉장실 내부의 구석구석까지 신속하게 골고루 제공될 수 있는 구조를 구비함으로써 냉장실의 고내온도 분포의 균일성이 향상되는 동시에 냉장실에 부하 투입시 부하 대응성이 향상되도록 하는 냉장고의 냉장실용 냉기 유로 장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, by having a structure in which the cold air supplied to the refrigerating compartment can be provided evenly to every corner of the refrigerating compartment to improve the uniformity of the high temperature distribution of the refrigerating compartment. At the same time, an object of the present invention is to provide a cold air passage for a refrigerator compartment of a refrigerator to improve load responsiveness when a load is put into a refrigerator compartment.

이후, 상기 멀티흡입덕트(53A)(53B)로 흡입된 냉기는 멀티흡입덕트(53A)(53B)를 따라 상측으로 이동된 다음 상단에 형성된 토출구멍(54)을 통해 배리어(57)의 냉장실용 냉기흡입유로(55A)(55B)로 이동된다.Thereafter, the cold air sucked into the multi suction ducts 53A and 53B moves upward along the multi suction ducts 53A and 53B, and then for the refrigerating chamber of the barrier 57 through the discharge hole 54 formed at the upper end. The cold air suction passages 55A and 55B are moved.
상기와 같이 배리어(57)의 냉장실용 냉기흡입유로(55A)(55B)로 유입된 냉기는 상기 냉장실용 냉기흡입유로(55A)(55B)를 통해 증발실로 공급된 후, 상기의 과정을 계속해서 반복하게 된다.As described above, the cold air introduced into the refrigerating chamber cold air suction passages 55A and 55B of the barrier 57 is supplied to the evaporation chamber through the refrigerating chamber cold air suction passages 55A and 55B, and then the process continues. Will repeat.
이와 같이 냉장실(R)의 유로 구조를 냉기가 각 칸별로 좌우 양측 후방에서 토출된 후 다시 각 칸별로 좌우 양측 전방으로 흡입되는 구조로 하면 상기 냉장실(R)의 구석구석까지 냉기가 신속하게 골고루 공급되게 된다.In this way, if the flow path structure of the refrigerating chamber (R) has a structure in which cold air is discharged from the left and right sides of each compartment, and then sucked back to the left and right sides of each compartment, the cold air is evenly supplied to every corner of the refrigerating compartment (R). Will be.
따라서, 상기 냉장실(R)의 고내온도 분포가 균일해져 냉장실(R)의 온도편차에 따라 발생되던 식품의 과냉, 약냉 현상이 방지되고, 이에 따라 상기 냉장실에 저장된 식품이 장기간 신선하게 보관되게 된다.Therefore, the high temperature distribution of the refrigerating compartment R is uniform, and the supercooling and weak cooling phenomenon of the food generated by the temperature deviation of the refrigerating compartment R is prevented, and thus the food stored in the refrigerating compartment is kept fresh for a long time.
뿐만 아니라, 상기 냉장실(R)의 냉각속도가 향상되어 냉장실(R)의 부하 투입시 부하 대응성이 향상되게 되므로 냉장실도어를 자주 개폐하는 여름철의 경우에도 상기 냉장실도어의 개폐에 따른 온도상승으로 인해 식품이 손상되는 일이 방지되게 된다.In addition, the cooling speed of the refrigerating compartment (R) is improved to improve the load responsiveness when the load of the refrigerating compartment (R) is increased, so even in the summer season when the refrigerating chamber door is frequently opened due to the temperature rise due to opening and closing the refrigerating compartment door Food damage is prevented.
특히, 상기 냉장실(R) 내부중 냉장실도어의 하단 근처는 냉기를 적게 받아 온도상승이 가장 우려되는 부분이었으나, 이 점은 상기 멀티흡입덕트(53A)(53B)를 이용한멀티 흡입 구조를 통해 고내온도 분포의 균일화가 이루어지므로 더 이상 염려하지 않아도 되게 된다.In particular, the inside of the refrigerating chamber (R) near the lower end of the refrigerating chamber door was less concerned with the increase in temperature, but this point is the high temperature through the multi-suction structure using the multi-suction duct (53A) (53B) Since the distribution is uniform, there is no need to worry anymore.
한편, 도 5는 본 발명의 다른 실시 예에 따른 냉장고의 냉장실용 냉기 유로 장치가 도시된 정면도로서, 이를 참조하면 본 발명의 다른 실시 예에서는 냉장실(R)로 냉기를 토출하기 위한 토출덕트(151)가 상기 냉장실(R)의 배면 상단부에 설치되어 냉장실(R)을 향해 냉기를 상측에서 하측으로 토출하도록 구성될 수도 있다. 이외의 구성 및 동작은 전술한 일 실시 예에 동일하다.On the other hand, Figure 5 is a front view showing a cold air flow path for the refrigerator compartment of the refrigerator according to another embodiment of the present invention, referring to the discharge duct 151 for discharging the cold air in the refrigerator compartment (R) in another embodiment of the present invention ) May be installed at the upper end of the rear surface of the refrigerating chamber (R) to discharge the cold air from the upper side to the lower side toward the refrigerating chamber (R). Other configurations and operations are the same in the above-described embodiment.
상기와 같은 본 발명에 따른 냉장고의 냉장실용 냉기 유로 장치는, 냉장실(R)로 공급된 냉기가 상기 냉장실(R) 내부의 구석구석까지 신속하게 골고루 제공되게 되므로 냉장실(R)의 고내온도 분포의 균일성이 향상되는 동시에 냉장실(R)에 부하 투입시 부하 대응성이 향상되는 이점이 있다.In the refrigerator cold air flow path device of the refrigerator according to the present invention as described above, since the cold air supplied to the refrigerating chamber (R) is provided evenly to every corner of the inside of the refrigerating chamber (R) of the high temperature distribution of the refrigerating chamber (R) The uniformity is improved and at the same time load responsiveness is improved when the load is put into the refrigerating chamber (R).
