본 발명은 냉장실 내부의 온도편차를 줄인 냉장고에 관한 것으로, 더욱 상세하게는 냉동실과 냉장실을 순환하는 냉기가 냉장실 선반에 식품이 재치되어 있는 경우에도 냉장실 내부에 균일하게 토출되도록 하여 보관되는 음식물의 신선도를 최적으로 유지할 수 있도록 한 냉장실 내부의 온도편차를 줄인 냉장고에 관한 것이다.The present invention relates to a refrigerator having a reduced temperature deviation in the refrigerating compartment, and more particularly, to a freshness of food stored by allowing the cold air circulating in the refrigerating compartment and the refrigerating compartment to be uniformly discharged in the refrigerating compartment even when the food is placed on the refrigerating compartment shelf. It relates to a refrigerator with reduced temperature deviation inside the refrigerating chamber to maintain the optimum.

제1도에 도시된 바와 같이, 일반적인 냉장고는 얼음그릇(1)이 슬라이딩되는 냉동실 선반(2), 도어산반(3)이 내측에 형성된 냉동실도어(4)를 구비한 냉동실(5)과, 냉기흡입구(6)를 통해 내동실(5)과 연통되는 냉장실(7)로 크게 구분되며, 냉장실(7)은 하측에 수납되는 야채실(8), 이의 상방으로 소정간격을 유지하는 수개의 냉동실 선반(9), 선반 상방에 온도 변화폭이 작아 보관되는 식품을 고유의 맛과 풍미를 유지하는 특선실(10), 수개의 도어선반(11)이 내측에 형성되는 냉장실도어(2), 모터팬(15)에 의해 냉기를 토출하는 증발기(36) 가동중 발생되는 응축수를 배출시키는 배수용 호스(13) 단부에 응축수 집수용 증발접시(14)가 설치되는 구조로 이루어진 것이다.As shown in FIG. 1, a typical refrigerator includes a freezer compartment 5 having a freezer compartment 2 in which an ice bowl 1 slides, a freezer compartment 5 having a door shelf 3 formed therein, and a cold air. The refrigerator compartment 7 is largely divided into a refrigerator compartment 7 communicating with the inner cavity 5 through the inlet 6, and the refrigerator compartment 7 includes a vegetable compartment 8 housed at a lower side thereof, and several freezer shelf shelves maintaining a predetermined interval upward. 9), a special chamber 10 for maintaining a unique taste and flavor of foods stored with a small temperature change range above the shelf, a refrigerating chamber door 2 in which several door shelves 11 are formed inside, and a motor fan 15 The condensate collecting evaporation plate 14 is installed at the end of the drain hose 13 for discharging the condensed water generated during operation of the evaporator 36 for discharging cold air.

그리고, 냉장고의 일반적인 냉동싸이클은 제2도에 개략적으로 도시된 바와 같이, 저온, 저압의 가스상태의 냉매를 흡입관(suction pipe)(31)를 통해 흡입 압축시켜 고온, 고압의 가스상태의 냉매로 변환시켜 송출관(discharge pipe)(32)을 통해 응축기(33)로 보내는 압축기(34)와, 고온, 고압의 냉매가 외부공기에 의해 열을 방출 냉각, 응축되어 액상의 냉매로 변환시키는 응축기(33)와, 고압, 액상의 냉매를 저온, 저압의 액상의 냉매로 변환시키는 모세관(35)(capillary tube)과, 주위로부터 열을 흡수 송풍기를 이용하여 실내공기를 저온으로 변환시키는 증발기(36)로 냉동싸이클을 구성하는 것이다.As shown in FIG. 2, a general refrigeration cycle of a refrigerator sucks and compresses a low-temperature, low-pressure gaseous refrigerant through a suction pipe 31 to form a high-temperature, high-pressure gaseous refrigerant. The compressor 34 converts the condenser 33 to a condenser 33 through a discharge pipe 32, and a condenser for discharging, condensing, and converting heat into a refrigerant in a liquid state by using high temperature and high pressure refrigerant. 33), a capillary tube for converting a high pressure, liquid refrigerant into a low temperature, low pressure liquid refrigerant, and an evaporator 36 for converting indoor air to a low temperature using a blower that absorbs heat from the surroundings. To form a refrigeration cycle.

따라서, 제2도에 도시된 냉장고의 냉동싸이클을 따라 생성되는 냉기는 증발기를 통해 냉장고 내부에 토출되어 냉기흡입구(6)를 통해 냉장실(7)과 냉동실(5)을 모터팬(15)에 의해 강제 순환되는 것이며(제1도에 화살표로 표기됨), 이에 따라 냉동실 선반(2)과 냉장실 선반(3)에 재치되는 음식물을 소정온도로서 유지하게 되며, 냉장실(7) 하측에 수납되는 야채실(8) 내부의 음식물은 이의 외주면에 접하는 냉기에 의해 내부의 온도는 낮으면서 습도는 적정을 유지하게 되는 것이다.Therefore, the cold air generated along the freezing cycle of the refrigerator shown in FIG. 2 is discharged into the refrigerator through the evaporator, and the refrigerating chamber 7 and the freezing chamber 5 are opened by the motor fan 15 through the cold air suction opening 6. It is forcedly circulated (indicated by an arrow in FIG. 1), and accordingly, foods placed on the freezer compartment 2 and the refrigerator compartment shelf 3 are maintained at a predetermined temperature, and the vegetable compartment housed below the refrigerator compartment 7 8) The food inside is cold due to its outer circumferential surface, so that the inside temperature is low and the humidity is maintained.

그러나, 냉장실(7)과 냉동실(5)을 순환하는 냉기를 토출하는 토출구가 냉장실(7) 후벽 또는 양측벽에 장착되므로, 냉장실(7) 후방에서 냉기를 토출시키는 경우에는 회전날개를 이용하여 냉기를 회전시켜 고 내부에 순환시키고 있으나, 냉동실 선반(9)에 음식물(가상선으로 도시됨)이 재치되어 있는 경우 구석 구석을 균일하게 냉각시키지 못하며, 또한 냉기토출구에 대해 야채실등은 거리차로 인해 냉장실 내부의 각 부위는 온도편차가 발생되는 것이었다. 한편, 냉장실(7) 양측벽에서 냉기를 토출시키는 경우에는 냉기의 토출 방향이 고정적이여 이 또한 냉장실 내부에 온도편차가 발생되어 냉각 효과가 미미하였다.However, since the discharge port for discharging the cold air circulating in the refrigerating chamber 7 and the freezing chamber 5 is mounted on the rear wall or both side walls of the refrigerating chamber 7, in the case of discharging the cold air from the rear of the refrigerating chamber 7, the cold air is rotated using a rotary blade. Rotating the inside of the refrigerator, but if the food (shown as a virtual vessel) is placed on the freezer shelf 9, it does not cool evenly every corner, and for the cold air outlet, the vegetable compartment, etc. due to the distance difference Each part in the interior was a temperature deviation. On the other hand, in the case of discharging cold air from both side walls of the refrigerating chamber 7, the discharge direction of the cold air is fixed, and the temperature deviation is generated inside the refrigerating chamber, so that the cooling effect is insignificant.

따라서, 본 발명의 목적은, 냉장고 내부를 순환하는 냉기가 냉장실 내부 구석 구석에 균일하게 토출되도록 하여 각 부위에서의 온도편차를 최소화하여 수납되는 음식물의 신선도를 최적의 상태로서 유지할 수 있도록 한 냉장실 내부의 온도편차를 줄인 냉장고를 제공하는데 있는 것이다.Accordingly, an object of the present invention is to ensure that the cold air circulating inside the refrigerator is evenly discharged in every corner of the inside of the refrigerator compartment, thereby minimizing the temperature deviation at each part to maintain the freshness of the food stored in the optimum state. It is to provide a refrigerator with a reduced temperature deviation.

위와 같은 본 발명의 작동을 설명하면, 제2도에 도시된 냉동사이클을 따라 생성되는 냉기가 증발기(36) 및 댐퍼(37)를 통해 냉장실(7)과 냉기흡입구(6)를 통해 연통되는 냉동실(5)을 순환하게 되는 것이며, 이때, 증발기(36)로부터 토출되는 냉기의 일부는 원통형인 냉기토출구(21)에 이의 상단 냉기유입구(23)를 통해 유입되며, 유입된 냉기는 내부의 회전체(25)에 의해 냉기토출구(21)의 원주면에 관통된 냉기배출공(24)을 통해 냉장실(7) 내부 구석 구석에 균일하게 토출되어지는 것이다.Referring to the operation of the present invention as described above, the freezer is generated through the refrigerating chamber 7 and the cold air inlet 6 through the evaporator 36 and the damper 37, the cold air generated along the freezing cycle shown in FIG. (5) is to be circulated, wherein a part of the cold air discharged from the evaporator 36 is introduced into the cylindrical cold air discharge port 21 through its upper cold air inlet 23, the introduced cold air is a rotating body therein (25) is uniformly discharged to every corner of the interior of the refrigerating chamber 7 through the cold air discharge hole 24 penetrating the circumferential surface of the cold air discharge port 21.

이에 따라 냉장실 선반(22)에 음식품이 재치되어 있는 경우에도 냉장실(7)을 순환하는 내부의 온도편차는 최소화가 가능한 것이다.Accordingly, even when food and drink are placed on the refrigerating compartment shelf 22, the temperature deviation inside the circulation of the refrigerating compartment 7 can be minimized.
