Description
본 발명은 에어커튼 냉장고에 관한 것으로, 특히 에어커튼용 덕트가 냉장실에 노출되도록 중간격에 설치하고, 에어커튼을 형성하기 위한 구동팬으로 원심팬을 사용한 에어커튼 냉장고에 관한 것이다.The present invention relates to an air curtain refrigerator, and more particularly, to an air curtain refrigerator using a centrifugal fan as a driving fan for installing an air curtain in an intermediate space such that the air curtain duct is exposed to a refrigerating chamber.
일반적인 에어커튼 냉장고의 일예는 도 1에 도시한 바와 같이, 냉동실(2)과 냉장실(3)을 구획하는 중간격(4)에 에어커튼용 덕트(5)를 설치하고, 상기 에어커튼용 덕트(5)의 토출측에 크로스플로우팬(6)을 구비한 구조이다.As an example of a general air curtain refrigerator, as shown in FIG. 1, an air curtain duct 5 is provided in an intermediate space 4 that divides the freezing compartment 2 and the refrigerating compartment 3, and the air curtain duct ( The crossflow fan 6 is provided on the discharge side of 5).
미설명 부호 1은 냉장고 본체, 7,8은 냉동실의 증발기와 송풍팬, 9,10은 냉장실의 증발기와 송풍팬이다.Reference numeral 1 denotes a refrigerator body, 7, 8 denotes an evaporator and a blower fan of a freezer compartment, and 9 and 10 denotes an evaporator and a blower fan of a refrigerating compartment.
이와 같은 구성을 갖는 에어커튼 냉장고는 냉장실의 도어가 닫힌 상태에서는 송풍팬(10)에 의하여 증발기(9)를 통과한 냉기가 고내로 토출되어 냉장실(3)의 내부를 순환한 후, 다시 증발기(9)로 유입되는 냉기의 순환경로를 형성한다.In the air curtain refrigerator having such a configuration, in the state in which the door of the refrigerating compartment is closed, the cold air passing through the evaporator 9 is discharged into the refrigerator by the blower fan 10, circulates inside the refrigerating compartment 3, and then evaporator ( 9) Form a circulation path of cold air flowing into.
또한, 도 1에서와 같이, 냉장실의 도어가 개방되면, 송풍팬(10)의 구동은 정지되고, 에어커튼용 덕트(5)의 크로스플로우팬(6)이 작동되어 증발기(9)를 통과한 냉기가 냉장실(3)의 상측에 설치된 에어커튼용 덕트(5)를 통과하여 냉장실의 상측에서 토출되도록 함으로써 냉장실(3)의 전면에서 냉기에 의한 에어커튼을 형성하게 된다.In addition, as shown in FIG. 1, when the door of the refrigerating chamber is opened, driving of the blower fan 10 is stopped, and the crossflow fan 6 of the air curtain duct 5 is operated to pass through the evaporator 9. The cold air passes through the air curtain duct 5 provided on the upper side of the refrigerating chamber 3 to be discharged from the upper side of the refrigerating chamber, thereby forming an air curtain by cold air on the front surface of the refrigerating chamber 3.
그러나 상기한 바와 같은 종래 기술에 의한 에어커튼 냉장고는 크로스플로우팬의 설치공간을 확보하기가 어려운 문제가 있다. 이는 프로펠러팬을 설치하는 경우에도 동일한 문제점으로 남는다.However, the air curtain refrigerator according to the prior art as described above has a problem that it is difficult to secure the installation space of the crossflow fan. This remains the same problem even when installing the propeller fan.
게다가 크로스플로우팬의 경우에는 냉기의 토출유량은 많지만 가격이 비싸고, 조립이 어렵다는 문제가 있고, 프로펠러팬의 경우에는 가격은 저렴하지만 유량이 작고 소음이 크다는 문제가 있다.In addition, in the case of the crossflow fan, there is a problem that the discharge flow rate of the cold air is high, but the price is high, and the assembly is difficult, and in the case of the propeller fan, there is a problem that the price is low but the flow rate is small and the noise is high.
또한, 상기한 바와 같이 크로스플로우팬이 토출측에 설치된 경우에는 냉기의 흡입경로가 길어지기 때문에 유로저항이 커지는 문제가 있다.In addition, when the crossflow fan is provided on the discharge side as described above, the suction path of the cold air becomes long, which causes a problem of increasing the flow resistance.
이러한 문제점을 감안하여 안출한 본 발명의 목적은 에어커튼용 덕트에 설치공간을 크게 차지하지 않는 범위에서 냉기를 토출시키도록 한 에어커튼 냉장고를 제공함에 있다.An object of the present invention devised in view of these problems is to provide an air curtain refrigerator to discharge cold air in a range that does not occupy a large space for installation in the air curtain duct.

이하, 상기한 본 발명 에어커튼 냉장고의 실시예를 첨부도면에 의거하여 보다 상세히 설명한다.Hereinafter, with reference to the accompanying drawings an embodiment of the present invention air curtain refrigerator will be described in more detail.
본 발명 실시예에 의한 에어커튼 냉장고의 본체(100)는 중간격(110)에 의해 냉동실(200)과 냉장실(300)로 구획되어 있고, 그 전면에는 도어(210)(310)가 개폐가능하게 설치되어 있다.The main body 100 of the air curtain refrigerator according to the embodiment of the present invention is divided into a freezing compartment 200 and a refrigerating compartment 300 by an intermediate space 110, and the doors 210 and 310 may be opened and closed at the front thereof. It is installed.
상기 냉동실(200)과 냉장실(300)에는 각각 수개의 선반(220)(320)이 구비되어 있고, 증발실에는 각각 증발기(230)(330)와 송풍팬(240)(340)이 설치되어 있으며, 냉장실(300)의 후방하측 기계실에는 압축기(400)가 설치되어 있다.The freezing chamber 200 and the refrigerating chamber 300 are provided with several shelves 220 and 320, respectively, and evaporators 230 and 330 and blowing fans 240 and 340 are respectively installed in the evaporation chamber. The compressor 400 is installed in the rear lower machine room of the refrigerating chamber 300.
또한, 상기 냉장실(300)의 상측에는 특선실(350)이, 하측에는 야채실(360)이 인출가능하게 설치되어 있다.In addition, a special selection chamber 350 is provided above the refrigerating compartment 300, and a vegetable compartment 360 is provided below the refrigerating compartment 300.
그리고 에어커튼을 실시하기 위한 구성으로서, 중간격(110)에는 에어커튼용 덕트(500)를 하면이 냉장실로 노출되도록 장착하고, 이 에어커튼용 덕트(500)의 흡입구(510)측에 원심팬(600)을 설치하며, 토출구(520)측에는 토출노즐(700)을 설치한 구성이다.The air curtain duct 500 is mounted on the intermediate space 110 such that the lower surface of the air curtain duct 500 is exposed to the refrigerating chamber, and the centrifugal fan is disposed on the suction port 510 side of the air curtain duct 500. A 600 is provided and a discharge nozzle 700 is provided at the discharge port 520 side.
상기 에어커튼용 덕트(500)는 도 3에서 보는 바와 같이, 원심팬(600)이 설치되기 위한 흡입구(510)에서 냉장실의 전면으로 개방되는 토출구(520)가 점점 넓어지는 냉기유로(530)가 방사형으로 형성되어 있고, 상기 냉기유로(530)에는 흡입구(510)에서 토출구(520)로 냉기를 균일하게 안내하는 수개의 에어가이더(540)가 설치되어 있다.As shown in FIG. 3, the air curtain duct 500 has a cold air flow passage 530 in which an outlet 520 opening to the front side of the refrigerating chamber is gradually widened at the inlet 510 for installing the centrifugal fan 600. The air flow passage 530 is radially formed, and several air guiders 540 are provided in the cold air passage 530 to uniformly guide the cold air from the suction port 510 to the discharge port 520.
이와 같이 에어커튼용 덕트의 냉기유로(530)에 에어가이더(540)가 설치되어 있는 경우에는 도 4a에 도시한 바와 같이, 냉기가 토출구(520)의 전범위에서 균일하게 토출되지만, 도 4b와 같이, 에어가이더가 설치되어 있지 않은 경우에는 토출구(520)의 일측으로 편향된 상태로 냉기가 토출되어 에어커튼을 형성하기 어렵게 된다.When the air guider 540 is installed in the cold air passage 530 of the air curtain duct as described above, as shown in FIG. 4A, the cold air is uniformly discharged in the entire range of the discharge port 520, but as shown in FIG. 4B. When the air guider is not installed, cold air is discharged while being deflected to one side of the discharge port 520, making it difficult to form an air curtain.
또한, 상기 원심팬(600)은 낮은 RPM 및 저소음 상태에서도 에어커튼을 형성하기 위한 충분한 냉기유량의 확보가 가능하며, 직류 또는 교류 모터(610)가 구동수단으로 설치되는 것이 바람직하다.In addition, the centrifugal fan 600 is capable of securing a sufficient cold air flow rate to form an air curtain even in a low RPM and low noise state, it is preferable that a direct current or alternating current motor 610 is installed as a driving means.
이와 같이 구성되어 있는 본 발명에 의한 에어커튼 냉장고의 작용을 설명한다.The operation of the air curtain refrigerator according to the present invention configured as described above will be described.
먼저, 도 5에 도시한 바와 같이, 냉장실 도어(310)가 닫혀있는 상태에서는 원심팬(600)은 정지되어 있는 상태이고, 냉장실의 송풍팬(340)만이 구동되어 증발기(330)를 통과하여 열교환된 저온의 냉기가 고내로 토출됨으로써 냉장실(300)의 내부에서 순환되며, 순환된 냉기는 다시 증발기(330)로 유입되어 다시 열교환되는 순환 구조가 이루어진다.First, as shown in FIG. 5, in the state where the refrigerating compartment door 310 is closed, the centrifugal fan 600 is stopped, and only the blowing fan 340 of the refrigerating compartment is driven to pass through the evaporator 330 to exchange heat. The low temperature cold air is discharged into the inside of the refrigerator compartment to circulate inside the refrigerating chamber 300, and the circulated cold air flows back into the evaporator 330 to form a heat exchange again.
그러다가 도 6에서와 같이, 냉장실 도어(310)가 개방되면, 도어와 연동되는 제어수단에 의하여 송풍팬(340)은 정지되고, 구동모터(610)를 구동시켜 에어커튼용 덕트(500)에 설치된 원심팬(600)만이 구동하게 된다.Then, as shown in FIG. 6, when the refrigerating compartment door 310 is opened, the blowing fan 340 is stopped by the control means interlocked with the door and drives the driving motor 610 to be installed in the air curtain duct 500. Only the centrifugal fan 600 is driven.
이와 같이 원심팬(600)이 구동됨으로써 고내의 냉기가 에어커튼용 덕트(500)의 흡입구(510)로 흡입되어 냉기유로(530)상의 에어가이더(540)에 의해 안내되면서 토출구(520)의 전면에 걸쳐서 균일하게 토출되어 냉장실(300)의 전면으로 에어커튼을 형성하게 된다.As the centrifugal fan 600 is driven as described above, the cold air in the refrigerator is sucked into the inlet 510 of the air curtain duct 500 and guided by the air guider 540 on the cold air flow path 530. It is uniformly discharged over and forms the air curtain to the front of the refrigerating chamber (300).
이때, 상기 토출구(520)에는 토출노즐(700)이 설치되어 있어 냉장실의 전면에서 보다 강력한 힘으로 에어커튼을 형성하게 된다.At this time, the discharge nozzle 700 is installed in the discharge port 520 to form an air curtain with a stronger force in the front of the refrigerating chamber.
다시 도어가 닫히게 되면, 원심팬(600)의 구동은 정지하고, 송풍팬(340)이 작동되어 일반적인 냉기의 순환작용을 실시하게 된다.When the door is closed again, the driving of the centrifugal fan 600 is stopped, and the blower fan 340 is operated to perform the circulation of general cold air.
이상에서 설명한 바와 같이, 본 발명에 의한 에어커튼 냉장고는 에어커튼을 형성하기 위한 구동팬으로서 원심팬을 사용함으로써 팬의 설치공간의 확보가 용이하다는 이점이 있고, 원심팬은 낮은 RPM 및 저소음 상태에서도 에어커튼을 형성하기 위한 충분한 냉기유량의 확보가 가능하다는 효과가 있다.As described above, the air curtain refrigerator according to the present invention has the advantage that the installation space of the fan can be easily secured by using the centrifugal fan as a driving fan for forming the air curtain, and the centrifugal fan has a low RPM and low noise. There is an effect that it is possible to secure a sufficient cold air flow rate for forming the air curtain.
또한, 원심팬의 설치위치가 에어커튼용 덕트의 흡입구측에 설치되어 냉기의 유로저항도 감소되는 효과가 있다.In addition, the installation position of the centrifugal fan is provided on the inlet side of the air curtain duct, thereby reducing the flow resistance of the cold air.
그리고 냉장실의 증발기를 통과시키지 않은 상태의 고내의 냉기만을 이용하여 에어커튼을 형성할 수 있는 이점도 있다.In addition, there is an advantage that the air curtain can be formed using only the cold air in the refrigerator without passing through the evaporator of the refrigerating chamber.
