본 고안은 냉장고의 냉기 순환구조에 관한 것으로, 특히 냉장 실내의 온도편차를 감소시켜 식품을 효과적으로 냉장할 수 있음과 아울러 냉장실내의 냉기의 토출량을 전체적으로 동시에 균일하게 조절할 수 있으며, 동절기에 냉장실을 사용하지 않을 경우에는 냉기가 냉장실로 공급되지 못하도록 완전히 차단함으로써 불필요한 전력낭비를 방지할 수 있도록 한 냉장고의 냉기 순환구조에 관한 것이다.The present invention relates to the cold air circulation structure of the refrigerator, and in particular, it is possible to effectively cool food by reducing the temperature deviation of the refrigerating room, and to control the discharge amount of the cold air in the refrigerating compartment as a whole at the same time, and use the refrigerating compartment in winter. If not, it relates to the cold air circulation structure of the refrigerator, which prevents unnecessary power waste by completely blocking cold air from being supplied to the refrigerating chamber.
종래 냉장고의 냉기 순환구조는 제 1 도에 도시한 바와같이, 증발기(11)에서 발생한 냉기가 팬(12)에 의하여 냉동실(17)과 냉장실(18)로 순환되어 냉장고내의 온도를 유지할 수 있도록 하고 있으며, 이때 증발기(11)에서 발생하여 팬(12)에 의하여 토출된 냉기가 냉장실(18)내에 설치되어 있는 냉기순환통(14)를 따라 내장실(18)내에서 화살표방향으로 순환되고, 냉장실(18)내의 자동온도조절장치(13)는 냉장실(18)의 온도를 감지하여 토출구(14a)를 개폐함에 따라 설정된 온도로 유지하도록 하고 있었다.As shown in FIG. 1, the cold air circulation structure of the conventional refrigerator allows the cool air generated in the evaporator 11 to be circulated by the fan 12 to the freezer compartment 17 and the refrigerating compartment 18 to maintain the temperature in the refrigerator. At this time, the cold air generated in the evaporator 11 and discharged by the fan 12 is circulated in the direction of the arrow in the interior chamber 18 along the cold air circulation cylinder 14 installed in the refrigerator compartment 18, The thermostat 13 in (18) sensed the temperature of the refrigerating chamber 18, and kept it at the set temperature by opening and closing the discharge port 14a.
그러나 이러한 종래의 냉기 순환구조에서는 토출구(14a)에서 냉장실(18)내로 토출된 냉기는 단순히 냉장실(18)의 상부로부터 내려오는 식으로 공급되기 때문에 각 선반(15a, 15b, 15c)에서의 온도차가 2°~3℃이상 발생되어 동일한 식품을 각 선반(15a, 15b, 15c)위에 보관할 경우 위와 같은 온도차에 의하여 식품의 보관정도도 달리하게 되며, 특히 냉기순환통로(14)의 바로 밑부분에 식품을 저장하게 될 경우 냉기의 순환이 원활하게 이루어지지 않아 각 선반부(15a, 15b, 15c)와 최하단에 위치하는 야채실(16)의 온도차는 더욱 크게 발생되어 야채의 보관시 변질을 초래하게 되는 등 냉장성능이 저하되는 문제점이 있었다.However, in the conventional cold air circulation structure, since the cold air discharged into the refrigerating chamber 18 from the discharge port 14a is simply supplied from the top of the refrigerating chamber 18, the temperature difference in each shelf 15a, 15b, 15c is different. When the same food is stored on each shelf (15a, 15b, 15c) because it occurs more than 2 ° ~ 3 ℃, the degree of storage of the food is also different according to the temperature difference as above, in particular the food immediately below the cold circulation passage (14) If it is stored in the cold air circulation is not made smoothly, the temperature difference between each shelf portion (15a, 15b, 15c) and the vegetable chamber 16 located at the bottom end is caused to be greater, causing deterioration during storage of vegetables, etc. There was a problem that the refrigeration performance is lowered.
또한 종래에는 일본 공개실용신안공보 실개소 58-63863호와 같이 냉동식품을 수용하는 냉장실의 일측벽 후방에 상방으로부터 하부에 이르게 점차 단면적이 축소되는 냉기유도덕트공을 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 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 냉기유도덕트공을 개폐하는 수단이 없기 때문에 냉기의 조절이 어렵고 동절기에 냉장실을 사용하지 않을 경우에도 냉장실로 냉기가 공급되어 불필요한 전력의 낭비를 초래하게 되는 문제점이 있었다.However, in such a device, since there is no means for opening and closing the cold air duct hole, it is difficult to control the cold air, and even when the cold room is not used in the winter, cold air is supplied to the cold room, causing unnecessary waste of power.
또한 종래에는 일본 공개실용신안공보 소101375호와 같이 냉장실의 온도감지부의 감열판의 수축 및 팽창에 따라 냉장실 각 단으로 보내지는 냉기를 단계적으로 차단시킬 수 있도록 한 댐퍼 및 유로 구조를 개시하고 있으나, 이러한 구조에서는 냉장실의 배면벽에 냉장실의 각 단벽로 대응하는 다수개의 냉기통로를 형성하고 이들 냉기통로를 선택적으로 개폐함으로써 냉기를 각 냉기통로를 통하여 냉장실의 각 단별로 공급할 수는 있으나, 냉장실 전체의 온도에 따라 냉장실 전체에 공급되는 냉기의 량을 일괄적으로 조절할 수 없으므로 각 단별로 각기 온도를 달리 조절할 수는 있으나 냉장실 전체의 온도를 일괄적으로 조절할 수 없으며, 상부 냉동실만 사용하고 싶을 때 인위적으로 냉장실 냉기통로를 폐쇄시킬 수 없고, 인장스프링이 냉기통로상에 위치하므로 스프링의 탄성력이 열적(熱的) 신뢰성이 우려되며, 스프링에 성애가 부착되어 가동불능현상이 자주 일어나게 되고, 냉기분배용 통로를 여러개 겹겹이 형성하였으므로 냉장실의 배면벽이 두껍고 무거워지게 되어 냉장고 전체가 무거워지며 재료비의 상승으로 인한 원가상승의 요인으로 되는 문제점이 있는 것이었다.In addition, the prior art discloses a damper and a flow path structure that can block the cold air sent to each stage of the refrigerating chamber step by step according to the contraction and expansion of the heat sensing plate of the temperature sensing unit of the refrigerating chamber, such as Japanese Utility Model Publication No. 101375, In this structure, by forming a plurality of cold passages corresponding to each end wall of the refrigerating compartment on the rear wall of the refrigerating compartment and selectively opening and closing these cold passages, the cold air can be supplied to each stage of the refrigerating compartment through each cold passage. Since the amount of cold air supplied to the whole refrigerating compartment can not be collectively controlled according to the temperature, it is possible to control the temperature of each stage differently, but it is impossible to control the temperature of the entire refrigerating compartment collectively. The cold air passage of the refrigerating chamber cannot be closed, and the tension spring is placed on the cold air passage. Therefore, the elastic force of the spring is concerned with thermal reliability, and the frost is attached to the spring, which often causes inoperability, and because several layers of cold air distribution passages are formed, the rear wall of the refrigerating chamber becomes thick and heavy, so that the entire refrigerator It is heavy and there is a problem of the cost increase due to the rise in material costs.
본 고안의 목적은 냉장실내의 온도차를 극소화하여 냉장고 내부 전체에 걸쳐서 균등한 냉장효과를 얻을 수 있으면서도 하나의 자동온도조절장치에 의하여 구동되는 개폐판에 의하여 각 선반과 야채실에 대응하는 각 토출구에서 토출되는 냉기의 토출량을 동시에 조절할 수 있음과 아울러 동절기에 냉장실을 사용하지 않을 경우에는 개폐판에 의하여 냉기순환통로를 완전히 차단함으로써 불필요한 전력의 낭비를 방지할 수 있도록 한 냉장고의 냉기 순환 구조를 제공하려는 것이다.The purpose of the present invention is to minimize the temperature difference in the refrigerating chamber and to achieve an even refrigeration effect throughout the inside of the refrigerator, while discharging from each outlet corresponding to each shelf and the vegetable compartment by an opening and closing plate driven by one thermostat. It is to provide a cold air circulation structure of the refrigerator that can simultaneously control the discharge amount of the cold air and to prevent unnecessary waste of electric power by completely blocking the cold air circulation passage by the opening and closing plate when the cold room is not used in winter. .
이러한 본 고안의 목적은, 냉장실의 배면측에 내측벽와 외측벽에 의하여 상단부에서 하단부에 이르는 냉기순환통로를 형성하고, 내측벽에는 다수개의 냉기토출구를 형성하며, 상기 냉기순환통로의 최상단에는 냉기순환통로 개폐수단을 구비한 것에 있어서, 상기 냉기순환통로 개폐수단은, 상기 냉기순환통로의 최상단을 완전히 막을 수 있는 크기의 개폐판과 이 개폐판을 개폐구동하는 자동온도조절장치로 구성되고, 냉기순환통로의 최상단에는 상기 개폐판이 걸리는 걸림턱(4a)을 형성하여서 된 것을 특징으로 하는 냉장고의 냉기 순환구조를 제공하는 것에 의하여 달성된다.The purpose of the present invention is to form 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 to form a plurality of cold air discharge ports on the inner wall, the cold air circulation passage at the top of the cold circulation passage In the opening and closing means, the cold air circulation passage opening and closing means is composed of an opening and closing plate of a size capable of completely blocking the top end of the cold air circulation passage and a thermostat for opening and closing the opening and closing plate, the cold air circulation passage It is achieved by providing a cold air circulation structure of the refrigerator, characterized in that by forming a locking jaw (4a) that the opening and closing plate is caught at the top.
