이하, 첨부된 도면에 의거하여 본 고안 일실시예의 구성을 상세히 설명하면 다음과 같다.Hereinafter, the configuration of an embodiment of the present invention in detail with reference to the accompanying drawings.

제2도는 본 고안에 적용되는 쇼우케이스의 개략측단면도써 이 쇼우케이스는 통상에서와 같이 본체(1)의 상부에 사각함체상의 저장실(2)이 구성되고, 그 하부에 기계실(5)이 구성되는 것으로, 상기 저장실(2)은 전방을 개구시켜 도어(3)를 설치하고 전방을 제외한 외곽에 단열재(11)를 발포시킨 후레임(10)에 의해 구성되며, 상부의 후방에는 증발기(41)와 제1송풍땐(42)을 장착시켜 열교환된 냉기를 저장실내로 순환시키는 열교환부(4)가 구비되고,2 is a schematic side cross-sectional view of a showcase applied to the present invention. The showcase includes a storage compartment 2 in a quadrangular enclosure at an upper portion of the main body 1 as in a conventional case, and a machine chamber 5 at a lower portion thereof. The storage compartment 2 is formed by a frame 10 that opens the front to install the door 3 and foams the heat insulating material 11 to the outside except the front, and the evaporator 41 and the rear of the upper part. The first blowing air 42 is provided with a heat exchanger 4 for circulating the heat exchanged cold air into the storage compartment,

상기 기계실(5)에는 응축기(51)와 압축기(52) 그리고 증발접시(53)가 장착되어 이루어진다.The machine room 5 is equipped with a condenser 51, a compressor 52, and an evaporation plate 53.

이러한 쇼우케이스에 있어서, 본 고안은 도어(3)의 개방시 열교환된 냉기를 저장실(2)이 전방으로 순환시켜 에어커텐(6)을 형성하는 냉기누설방지장치를 구성하게 되는 것으로, 이는 열교환부(4)의 전방에 하향으로 만곡되는 안내부재(61)를 구성하고, 저장실(2)이 하부에는 상기 안내부재(61)와 대향하게 유입구(62a)가 통공되고 후방에 열교환부(4)의 제1송풍팬(42)과 대향하기 배출구(62b)가 통공되어 서로 연통되는 순환덕트(62)를 구성하여 그 내부의 소정위치에 후향으로 송풍력을 발생시키는 제2송풍팬(63)을 장착시킨다.In this showcase, the present invention is to configure a cold air leakage preventing device for circulating the cold air heat exchanged when the door 3 is opened forward to form an air curtain (6), which is a heat exchange unit The guide member 61 is bent downward in front of the (4), the inlet (62a) is through the storage chamber (2) facing the guide member 61 in the lower portion of the heat exchange section (4) The second blower fan 63 is formed to form a circulation duct 62 through which the discharge port 62b is opposed to the first blower fan 42 so as to communicate with each other. Let's do it.

그리고, 도어(3)의 배면이 밀착되는 후레임(10)전면의 소정위치에는 제3도에서와 같이 도어(3)의 폐쇄시 제1송풍팬(42)만을 구동시키고, 도어(3)의 개방시에는 제2송풍팬(63)만을 구동시키는 스위치(64)를 장착하게 되는 것이다.Then, only the first blowing fan 42 is driven when the door 3 is closed, as shown in FIG. 3, at a predetermined position on the front of the frame 10 to which the rear surface of the door 3 is in close contact, and the door 3 is opened. At the time, the switch 64 for driving only the second blowing fan 63 is mounted.

이상에서와 같이 구성된 본 고안의 동작과정과 그에 따른 작용효과를 상세히 설명하면 다음과 같다.Referring to the operation process of the present invention configured as described above and the effect according to it in detail as follows.

먼저, 도어(3)가 폐쇄되어 정상적인 냉각기능을 수행할 때에는 도어(3)의 가압에 의해 스위치(64)의 접점(a)가 접지되어 제1송풍팬(42)의 모터에 전원을 인가시키게 되고, 이렇게 전원이 인가되어 제1송풍팬(42)을 구동시키게 되면 통상에서와 같이 증발기(41)로 부터 열교환된 냉기가표 방향을 따라 순환되어지는 것이며, 이러한 상태에서 저장실(2)내에 저장된 식품을 인출시키거나 새로운 식품을 저장하기 위해 도어(3)를 개방시켜 도어(3)의 가압력이 스위치(64)로 부터 해제되면 접점(b)측으로 접지되어 제1송풍팬(42)의 구동을 정지시킴과 동시에 제2송풍팬(63)의 모터에 전원을 인가시켜 제2송풍기(63)를 구동시킨다.First, when the door 3 is closed to perform a normal cooling function, the contact a of the switch 64 is grounded by the pressure of the door 3 to apply power to the motor of the first blowing fan 42. When the power is applied to drive the first blower fan 42, the cold air that is heat-exchanged from the evaporator 41, as usual, In this state, the pressure is released from the switch 64 by opening the door 3 to withdraw the food stored in the storage compartment 2 or storing new food. If the contact point (b) is grounded to stop the driving of the first blower fan 42 and at the same time to apply power to the motor of the second blower fan 63 to drive the second blower (63).

이렇게 제1송풍팬(42)의 구동정지와 동시에 제2송풍팬(63)이 구동되어 순환덕트(62)의 후향으로 송풍력을 발생시키게 되면 증발기(41)로 부터 열교환된 냉기는 ..방향을 따라 열교환부(4)전방의 안내부재(61)에 의해 안내도어 순환덕트(62)의 유입구(62a)를 통해 후방의 배출구(62b)로 배출되고, 배출된 냉기는 그 직상부에 통공된 열교환부(4)의 토출구(4a)를 통해 유입되어 열교환을 이룬후 상기에서와 같은 순환과정을 연속적으로 수행하면서 저장실(2)의 개구부 전면에 에어커탠(6)을 형성시키게 되는 것이다.When the second blower fan 63 is driven at the same time as the driving stop of the first blower fan 42 is generated to generate a blowing force in the backward direction of the circulation duct 62, the cold heat exchanged from the evaporator 41 .. Direction is discharged to the rear outlet port 62b through the inlet port 62a of the guide door circulation duct 62 by the guide member 61 in front of the heat exchange unit 4, and the discharged cold air flows through the upper portion thereof. After the heat exchange is introduced through the discharge port 4a of the heat exchanger 4 to form a heat exchange, the air curtain 6 is formed on the entire surface of the opening of the storage chamber 2 while continuously performing the circulation process as described above.

이상에서와 같이 도어의 개방시 저장실의 전면에 형성되는 에어커탠은 저장실내의 냉기 외부로 누설되는 것을 방지할 뿐만 아니라 높은 온도의 외부공기가 저장실내로 유입되는 것을 방지하게 되므로써 도어개방시에도 냉각효율을 정상적으로 유지시킴은 물론 소비전력이 불필요하게 소모되는 것을 방지하는 효과를 얻을수 있는 것이다.As described above, the air curtain formed on the front surface of the storage compartment when the door is opened not only prevents leakage of cold air into the storage compartment but also prevents high temperature external air from entering the storage compartment, thereby cooling the door. The efficiency can be maintained as well as to prevent unnecessary power consumption.
