본 발명은 에어커튼형성장치를 구비한 냉장고에 관한 것으로서, 특히 냉장고의 도어개구 전면에 가로방향의 에어커튼을 형성하도록 한 냉장고에 대한 것이다.The present invention relates to a refrigerator having an air curtain forming apparatus, and more particularly, to a refrigerator having a horizontal air curtain formed on the front surface of a door opening of the refrigerator.
종래의 냉장고 중에는 도어의 개방시 외부온기의 침입이나 내부냉기의 유출에 의한 효율저하를 방지하기 위해 도어개구전면에 상하방향의 에어커튼이 형성될 수 있도록 한 것이 개발되어 있다.The conventional refrigerator has been developed so that the air curtain in the up and down direction can be formed on the front surface of the door to prevent the decrease in efficiency due to intrusion of external warmth or leakage of internal cold air when the door is opened.
이러한 종래의 냉장고에서는, 도어개구전면에 에어커튼을 형성하기 위하여 냉장실의 상부에 에어커튼덕트를 마련하고, 이 에어커튼덕트를 통해 증발기에 인접하여 설치된 송풍팬으로부터 냉기를 급송한다. 그런데, 에어커튼덕트의 토출구는 송풍팬으로부터 비교적 멀리 위치하여 있으므로 긴 덕트를 거친 냉기는 유동성이 저하되어 에어커튼형성이 미약할 수 있다. 그리고, 이러한 상하방향의 수직형 에어커튼은 냉장실내의 선반이나 물품들에 의해 도중에서 차단되는 경우가 발생할 수 있다.In such a conventional refrigerator, an air curtain duct is provided in the upper part of the refrigerating chamber in order to form an air curtain on the front surface of the door, and the cold air is fed from the blower fan provided adjacent to the evaporator through the air curtain duct. However, since the discharge port of the air curtain duct is located relatively far from the blower fan, the cold air passing through the long duct may have low fluidity and weak air curtain formation. In addition, the vertical air curtain in the vertical direction may be blocked in the middle by shelves or articles in the refrigerating chamber.
따라서, 본 발명의 목적은, 이러한 문제점을 고려하여, 냉장고의 개구전면에 보다 강하게 가로방향의 에어커튼을 형성함으로써, 냉기손실 없이 음식물을 신선하게 보관할 수 있는 에어커튼 형성장치를 구비한 냉장고를 제공하는 것이다.Accordingly, an object of the present invention is to provide a refrigerator having an air curtain forming apparatus that can store food freshly without loss of cold air by forming an air curtain in the transverse direction more strongly on the front surface of the opening of the refrigerator in view of such a problem. It is.
상기 목적은, 냉장고에 있어서, 증발기로 부터의 급송냉기를 공급받아 냉장실의 소정개소에 위치한 토출구를 통해 냉기를 토출하는 냉기덕트와; 도어개구의 일측면에 세로로 형성되어 대향측측면을 향해 공기를 토출하는 토출구를 가지는 에어커튼덕트와; 상기 에어커튼덕트내에 공기유동을 형성하는 횡류팬과; 상기 도어의 개폐를 감지하는 도어개폐감지수단과; 상기 도어개폐감지수단에 의한 도어개방감지시 상기 횡류팬을 작동시켜 에어커튼을 형성토록 하는 제어부를 포함하는 것을 특징으로 하는 에어커튼형성장치를 구비한 냉장고에 의하여 달성된다.The object of the present invention is to provide a refrigerator comprising: a cold air duct for supplying cold air from an evaporator to discharge cold air through a discharge port located at a predetermined location of a refrigerating chamber; An air curtain duct formed vertically on one side of the door opening and having a discharge port for discharging air toward the opposite side surface; A cross flow fan forming air flow in said air curtain duct; Door opening and closing detecting means for detecting opening and closing of the door; It is achieved by a refrigerator having an air curtain forming apparatus, characterized in that it comprises a control unit for operating the cross flow fan to form an air curtain when the door opening is detected by the door opening and closing detecting means.
여기서, 횡류팬은 냉장실의 후방벽의 중앙영역에 설치하고, 냉장실내의 공기 유입을 위한 유입구를 갖도록 할 수 있고, 이때 에어커튼덕트의 토출구에 대향한 대향측 측면에는 토출구에서 토출된 공기유동을 냉장실내부로 향하도록 안내하는 유로안내턱을 형성하는 것이 바람직하다. 또한 횡류팬을 도어폐쇄시 간헐적으로 작동하도록 하여, 냉장실내의 냉기를 교반시킬 수 있다.Here, the cross flow fan may be installed in the central region of the rear wall of the refrigerating compartment, and may have an inlet for inflow of air in the refrigerating compartment. It is preferable to form a flow path guide jaw to guide toward the inside of the refrigerator compartment. In addition, the cross flow fan can be intermittently operated when the door is closed to stir the cold air in the refrigerating compartment.
이하에서는 도면을 참조하여 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the drawings.
제1도는 본 발명에 따른 냉장고의 도어개방시의 사시도이고, 제2도는 제1도의 횡단면도이다. 이들 도면에서 볼 수 있는 바와 같이, 본 냉장고는, 다수의 선반(13)에 의해 층상으로 구획되어 있는 냉장실(1)의 상측에 특선실(11)이, 하측에 야채실(12)이 각각 마련되어 있다. 냉장실(1)의 후방벽면에는 도시않은 증발기로 부터의 냉기가 유동하는 냉기덕트(4)의 토출구(6)가 각 선반(13)에 대응하는 위치에 좌우 2열로 배열되어 있다.1 is a perspective view of the door opening of the refrigerator according to the present invention, Figure 2 is a cross-sectional view of FIG. As can be seen from these figures, in the present refrigerator, a special chamber 11 is provided on the upper side of the refrigerating chamber 1 partitioned into layers by a plurality of shelves 13, and a vegetable chamber 12 is provided on the lower side, respectively. . On the rear wall surface of the refrigerating chamber 1, discharge ports 6 of the cold air duct 4 through which cold air from an evaporator (not shown) flows are arranged in two rows at right and left at positions corresponding to the shelves 13.
냉기유출구(6)사이의 중앙영역에는 냉장실(1)내의 냉기가 회수되는 유입구(8)가 좌우배열된 토출구(6)들 사이에 각각 형성되어 있다. 이 유입구(8)의 내부에는 유입구(8)를 통해 냉장실(1)내의 냉기를 흡입하여 냉기를 측방향으로 급송하는 횡류팬(3)이 설치되어 있으며, 이 횡류팬(3)은 세로방향의 회전축(15a, 15b)에 의해 회전가능하게 설치되어 있다. 횡류팬(3)의 하부의 회전축(15b)은 구동모터(9)에 연결되어 있어, 구동모터(9)에 의해 회전구동된다.In the central region between the cold air outlets 6, inlets 8 for collecting cold air in the refrigerating chamber 1 are formed between the outlets 6 arranged left and right. Inside the inlet 8 is provided with a cross flow fan 3 for sucking cold air in the refrigerating chamber 1 through the inlet 8 and feeding the cool air in a lateral direction. The cross flow fan 3 has a longitudinal direction. Rotation is provided by the rotation shafts 15a and 15b. The rotary shaft 15b at the lower portion of the cross flow fan 3 is connected to the drive motor 9, and is rotated by the drive motor 9.
한편, 냉장실(1)의 일측벽에는, 도어개구에 인접하여 세로로 형성된 토출구(7)를 가지고 횡류팬(3)으로부터 냉기를 급송받는 에어커튼덕트(5)가 마련되어 있다. 에어커튼덕트(5)의 토출구(7)는 횡류팬(3)으로부터 공급된 냉기를 대향하는 측벽을 향하여 토출하며, 이에 의해 도어(2)개구의 전면에 가로방향으로의 에어커튼이 형성된다.On the other hand, one side wall of the refrigerating chamber 1 is provided with an air curtain duct 5 having a discharge port 7 formed vertically adjacent to the door opening and feeding cold air from the cross flow fan 3. The discharge port 7 of the air curtain duct 5 discharges toward the side wall facing the cold air supplied from the cross flow fan 3, whereby an air curtain in the transverse direction is formed on the front surface of the door 2 opening.
한편, 토출구(7)에 대향한 측벽에는 토출구(7)로 부터의 냉기의 유동을 냉장실(1)내부로 향하도록 안내하는 유로안내턱(16)이 형성되어 있다. 또한, 냉장실(1)의 도어개구측 상부에는 냉장실(1)의 냉기를 흡입하는 흡입구(10)가 형성되어 있다.On the other hand, a sidewall facing the discharge port 7 is provided with a flow path guide jaw 16 for guiding the flow of cold air from the discharge port 7 to the inside of the refrigerating chamber 1. In addition, a suction port 10 for sucking cold air in the refrigerating chamber 1 is formed at an upper portion of the door opening side of the refrigerating chamber 1.
이러한 구성에 의하여, 냉장고의 도어(2)가 폐쇄된 경우에는 폐쇄상태의 횡단면도를 도시한 제3도에서 볼 수 있는 바와 같이, 도시않은 증발기로 부터의 냉기가 냉장실(1)의 후방벽면에 형성된 냉기덕트(4)의 토출구(6)를 통해 토출되어 냉장실(1)을 냉각시키며, 냉장실(1)내의 냉기는 도어개구측 상부에 마련된 흡입구(10)를 통하여 회수되게 된다. 이 때 횡류팬(3)은 정지상태로 있거나, 혹은 간헐적으로 회전하여 냉장실(1)내의 냉기를 교반시키는 역할을 할 수 있다.By this configuration, when the door 2 of the refrigerator is closed, as shown in FIG. 3 showing a cross-sectional view of the closed state, cool air from an evaporator (not shown) is formed on the rear wall surface of the refrigerating chamber 1. It is discharged through the discharge port 6 of the cold air duct 4 to cool the refrigerating chamber 1, and the cold air in the refrigerating chamber 1 is recovered through the inlet 10 provided at the upper side of the door opening side. At this time, the cross flow fan 3 may be in a stationary state, or may intermittently rotate to stir cold air in the refrigerating chamber 1.
그리고, 냉장고의 도어(2)가 개방되면, 도시않은 도어개폐감지수단이 도어개방을 나타내는 신호를 도시않은 제어부에 제공하고 이 제어부는 냉기덕트(4)를 통한 냉기공급을 차단하는 한편, 횡류팬(3)의 구동모터(9)를 작동시켜 횡류팬(3)을 회전시킨다. 이에 의해 냉장실(1)내의 냉기는 제2도에 화살표로서 표시되어 있는 바와 같이, 유입구(8)를 통해 유입되어, 횡류팬(3)의 강제급송에 의해 에어커튼덕트(5)내의 유로를 유동하여 도어개구측 측벽에 세로로 형성된 토출구(7)를 통하여 토출되게 된다. 이때 토출되는 냉기는 도어(2)개구면을 따라 가로방향의 균일하고 강한 에어커튼을 형성한다. 또한, 에어커튼을 형성한 냉기는 유로안내턱(16)의 안내에 의하여 냉장실(1)내부로 유도되어 횡류팬(3)에 의해 다시 에어커튼덕트(5)내로 급송되게 된다.When the door 2 of the refrigerator is opened, a door opening / closing detection means (not shown) provides a signal indicating the opening of the door to the control part (not shown), which blocks the supply of cold air through the cold air duct (4), and the cross flow fan. The drive motor 9 of (3) is operated to rotate the crossflow fan 3. As a result, the cold air in the refrigerating chamber 1 flows in through the inlet port 8, as indicated by the arrow in FIG. 2, and flows through the flow path in the air curtain duct 5 by forced feeding of the cross flow fan 3. The discharge port 7 is discharged through the discharge port 7 formed vertically on the side wall of the door opening side. The cold air discharged at this time forms a uniform and strong air curtain in the transverse direction along the opening surface of the door 2. In addition, the cold air in which the air curtain is formed is guided to the inside of the refrigerating chamber 1 by the guide of the flow path guide jaw 16, and is supplied to the air curtain duct 5 by the cross flow fan 3 again.
이상 설명한 바와 같이, 본 발명에 따른 에어커튼형성장치를 구비한 냉장고는 냉장고의 개구전면에 보다 강하게 가로방향의 에어커튼을 형성할 수 있어 냉기손실없이 음식물을 신선하게 보관할 수 있다.As described above, the refrigerator provided with the air curtain forming apparatus according to the present invention can form the air curtain in the transverse direction more strongly on the front surface of the opening of the refrigerator can keep the food fresh without cold air loss.
