본 고안은 냉기순환구조가 개선된 냉장고에 관한 것으로, 특히 냉장실 내부의 상하 온도편차를 감소시켜 식품을 효과적으로 냉장할 수 있고, 냉장실내의 냉기분포를 전체적으로 동시에 균일하게 할 수 있도록 냉장실에 설치되는 다단의 선반 내부로 냉기를 토출시키도록 한 냉장고에 관한 것이다.The present invention relates to a refrigerator having an improved cold circulation structure, and in particular, it is possible to effectively cool foods by reducing the vertical temperature difference inside the refrigerator compartment, and to be installed in the refrigerator compartment so that the distribution of the cold air in the refrigerator compartment as a whole is uniform at the same time. It relates to a refrigerator for discharging cold air into the shelf of the.

종래 냉장고의 냉기순환구조는 제1도에 도시한 바와 같이, 증발기(10)에서 발생한 냉기가 팬(12)에 의하여 냉동실(16)과 냉장실(18)로 순환되어 냉장고 내의 저온을 유지할 수 있도록 되어 있으며, 이때 증발기(10)에서 발생된 냉기는 팬(12)에 의하여 토출되고, 이는 냉장실(18)내에 설치되어 있는 냉기순환통로(19)를 따라 냉장실(18)내에서 화살표 방향으로 순환되고, 냉장실(18)내의 자동온도조절장치(20)는 냉장실(18)의 온도를 감지하여 토출부(22)를 개폐함에 따라 설정된 온도가 유지되도록 하고 있다.In the conventional cold air circulation structure of the refrigerator, as shown in FIG. 1, cold air generated in the evaporator 10 is circulated by the fan 12 to the freezer compartment 16 and the refrigerating compartment 18 to maintain a low temperature in the refrigerator. At this time, the cool air generated in the evaporator 10 is discharged by the fan 12, which is circulated in the direction of the arrow in the refrigerating chamber 18 along the cold air circulation passage 19 installed in the refrigerating chamber 18, The thermostat 20 in the refrigerating chamber 18 senses the temperature of the refrigerating chamber 18 and maintains the set temperature by opening and closing the discharge unit 22.

그러나 이러한 종래의 냉기 순환구조에서는 토출부(22)에서 냉장실(18)내로 토출된 냉기가 단순히 냉장실(18)의 상부에서 하부로 자연 하강되는 식으로 공급되며 하강되던 냉기가 각 선반(24)에서 차단되기 때문에 냉장실(18) 하부의 온도가 냉장실(18)상부의 온도보다 약 2oC∼3oC 이상 높게되어 동일한 식품을 각 선반(24)위에 보관할 경우 상기와 같은 온도차에 의하여 식품의 보관정도 및 보관기간이 다르게 되며, 특히 선반(24)의 최하단에 위치하는 야채실(14)의 온도차는 더욱 크게 발생되어 상기 야채실(14)내의 야채가 짧은 기간 내에 변질되는 등의 냉장성능이 저하되는 폐단이 있었다.However, in the conventional cold air circulation structure, the cold air discharged from the discharge part 22 into the refrigerating chamber 18 is supplied in such a manner as to naturally descend from the upper part of the refrigerating chamber 18 to the lower part, and the cold air that has been lowered is discharged from each shelf 24. storage of foods by the temperature difference as described above when the same food is kept below the temperature of the refrigerating compartment 18 is higher refrigerating compartment (18) above the temperature of the upper portion 2 about C~3 o o C or above each shelf (24) since the block The degree and storage period will be different, in particular, the temperature difference between the vegetable chamber 14 located at the bottom of the shelf 24 is more large, resulting in a decrease in refrigeration performance such as deterioration of the vegetables in the vegetable chamber 14 within a short period of time. There was this.

또한 종래에는 일본 공개실용신안공보 실개소 58-63863호와 같이 냉동식품을 수용하는 냉장실의 일측벽 후방에 상방으로부터 하부에 이르게 점차 단면적이 축소되는 냉기유도 덕트공을 형성하고 상기 냉장실에 덕트공에 대향하는 송풍구를 복수개 설치하여 덕트공으로부터 공급되는 냉기가 각 송풍공을 통하여 각 선반등에 공급되도록 한 것이 안출되어 있다.Also, conventionally, as shown in Japanese Laid-Open Utility Model Publication No. 58-63863, a cold air induction duct hole is formed at the rear of one side wall of the refrigerating chamber that accommodates frozen foods and gradually decreases in cross-sectional area from the upper side to the lower side. It is conceivable that a plurality of opposed blow holes are provided so that the cold air supplied from the duct hole is supplied to each shelf through each blow hole.

그러나 이러한 장치에서는 냉기유도 덕트공을 개폐하는 수단이 없기때문에 냉기의 조절이 어렵고 동절기에 냉장실을 사용하지 않을 경우에도 냉장실로 냉기가 공급되어 불필요한 전력의 낭비를 초래하게되는 문제점이 있었다.However, in such a device, since there is no means for opening and closing the duct hole for cold air, it is difficult to control cold air, and even when the cold room is not used in winter, cold air is supplied to the cold room, causing unnecessary waste of power.

상기 이외에도 일본 공개실용신안공보 소 101375호와 같이 냉장실의 온도감지부의 감열판의 수축 및 팽창에 따라 냉장실 각 단으로 보내지는 냉기를 단계적으로 차단시킬 수 있도록 댐퍼 및 유로구조를 갖춘것이 있으며, 이러한 구조에서는 냉장실의 배면벽에 냉장실의 각 단별로 대응하는 다수개의 냉기 통로를 선택적으로 개폐함으로써 냉기를 각 냉기 통로를 통하여 냉장실의 각 단별로 공급할 수 있으나 냉장실 전체의 온도에 따라 냉장실 전체에 공급되는 냉기의 양을 일괄적으로 조절할 수 없으므로 각 단별로 각기 온도를 달리 조절할 수 있는 반면에 냉장실 전체의 온도를 일괄적으로 조절헐 수 없으며, 상부 냉동실만 사용하고 싶을 때에도 인위적으로 냉장실 냉기통로를 폐쇄시킬 수 없고, 인장스프링이 냉기통로 상에 위치하므로 스프링탄성력의 열적 신뢰성이 우려되며, 스프링에 성애가 착상되어 가동불능 현상이 자주 일어나게 되고 냉기 분배용 통로를 여러개 중첩되게 형성하였으므로 냉장실의 배면벽이 두껍고 무거워지게 되는 문제점이 있는 것이었다.In addition to the above, there is a damper and a flow path structure so that the cold air sent to each stage of the refrigerator compartment can be blocked step by step by contraction and expansion of the heat sensing plate of the temperature sensing unit of the refrigerator compartment, such as Japanese Utility Model Publication No. 101375. By selectively opening and closing a plurality of cold air passages corresponding to each stage of the refrigerating compartment on the rear wall of the refrigerating compartment, cold air can be supplied to each stage of the refrigerating compartment through each cold air passage, but according to the temperature of the refrigerating compartment, Because the quantity cannot be adjusted in a batch, the temperature can be adjusted differently for each stage, while the temperature of the whole refrigerating compartment cannot be controlled in a batch, and even when only the upper freezer is desired, the cold passage of the refrigerating compartment cannot be artificially closed. Spring elasticity as the tension spring is located on the cold passage And the possibility that thermal reliability, which was a problem is the sexual implantation downtime phenomenon often occurs in the spring, and that would be the rear wall of the refrigerator compartment thick and heavy hayeoteumeuro formed to overlap the multiple passages for cooling air distribution.

또한 한국 실용신안공고 제93-8688호에는 냉장실의 배면측에 내측벽과 외측벽에 의하여 상단부에서 하단부에 이르는 냉기순환 통로를 형성하고 내측벽에는 다수개의 냉기토출구를 형성하며, 냉기 순환통로의 최상단에는 냉기순환통로 개폐수단인 개폐판과 자동 온도조절장치를 부착하여 다수개의 냉기토출구를 통하여 냉기를 토출시킴으로써 냉장실내의 온도를 균일하게 유지시킬 수 있도록 하였으나 이는 냉장실의 배면 내측으로부터만 냉기가 공급되기 때문에 각 선반에 보관되는 제품을 효과적으로 냉장 보관시키기에는 미흡한 결점이 있었다.In addition, Korean Utility Model Publication No. 93-8688 forms a cold air circulation passage from the upper end to the lower end by the inner wall and the outer wall on the rear side of the refrigerating chamber, and forms a plurality of cold air discharge outlets on the inner wall, and at the top of the cold air circulation passage. Opening / closing plate and automatic temperature control device, which is a means of opening and closing the cold air circulation passage, discharge the cold air through a plurality of cold air outlets, so that the temperature in the refrigerating chamber can be maintained uniformly. There was a lack of effective refrigeration of the products stored on each shelf.

본 고안은 상기와 같은 종래 냉장고의 냉기순환 구조의 폐단을 해소하기 위하여 안출한 것으로서, 냉잘실내 상하부간의 온도차를 극소화하여 냉장고 내부전체에 걸쳐서 균일한 냉장효과를 얻을 수 있는 냉장고를 제공하는데 본 고안의 목적이 있는 것이다.The present invention devised to solve the closed end of the cold air circulation structure of the conventional refrigerator as described above, by minimizing the temperature difference between the upper and lower parts in the cold-jail chamber to provide a refrigerator that can obtain a uniform refrigeration effect throughout the inside of the refrigerator. There is a purpose.

상기의 목적을 달성하기 위한 본 고안은 냉장실의 양측면에 냉장실 내로 향하는 냉기토출구를 형성하고, 선반의 양측면에는 그 내부를 관통하는 냉기통로를 형성하여 선반의 하면으로 연통되는 다수개의 냉기 배출구로 냉기가 배출되도록 하며, 선반을 선반 지지대에 안치하는 경우에 선반의 냉기 통로가 냉기토출구와 일치되어 냉기가 냉장실 측면의 냉기토출구를 통하여 선반으로 유입되어 선반 하단의 냉기 배출구로 배출되게 함으로써 냉장실내의 온도분포를 단시간내에 균일하게 할 수 있는 구조로 되어있다.The present invention for achieving the above object is to form a cold air discharge port toward both sides of the refrigerating chamber in the refrigerating chamber, and on both sides of the shelf to form a cold air passage passing through the inside of the plurality of cold air outlets communicated to the lower surface of the shelf When the shelf is placed on the shelf support, the cold air passage of the shelf coincides with the cold air outlet so that cold air flows into the shelf through the cold air outlet on the side of the refrigerator compartment and is discharged to the cold air outlet at the bottom of the shelf. It has a structure that can make uniform even in a short time.
