Description
본 발명은 냉장고에 관한 것으로서, 보다 상세하게는 플라스틱 증발기가 구비된 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly to a refrigerator equipped with a plastic evaporator.
냉장고는 음식물 등을 냉동시키거나, 냉장보관하기 위해 사용되는 것으로서, 도 1에 나타난 것과 같이 내부에 냉동실(101)과 냉장실(102)로 분리된 수납공간을 형성하는 케이스(10) 및 상기 케이스(10)의 일측에 장착되어 냉동실(101)과 냉장실(102)을 개폐하는 냉동 냉장실 도어(12)와, 압축기(20), 응축기(30) 및 증발기(40) 등과 같이 냉동사이클을 이루어 냉기를 형성하는 기기들을 포함하여 구성되어 있다.The refrigerator is used to freeze or refrigerate food or the like, and as shown in FIG. 1, a case 10 and a case (10) forming a storage space separated into a freezing compartment 101 and a refrigerating compartment 102 as shown in FIG. 1. 10 is formed on one side of the freezer compartment door 12 for opening and closing the freezer compartment 101 and the refrigerating compartment 102, and forming a cold cycle such as the compressor 20, the condenser 30 and the evaporator 40 to form cold air It is configured to include devices.
이러한 냉장고에서는 압축기(20)에 의해 저온 저압의 기상 냉매가 고온 고압으로 압축되고, 압축된 고온 고압의 기상 냉매가 응축기(30)를 지나는 과정에서 냉각 응축되어 고압의 액상으로 전환되며, 고압의 액체상태로 된 냉매는 모세관(미도시)을 통과하면서 그 온도와 압력이 낮아진 다음, 계속해서 증발기(40)에서 저온 저압의 기체상태로 변하면서 주위로부터 열을 빼앗아 그 주위의 공기를 냉각시키게 된다. 상기 증발기(40)는 냉동실(101) 후면의 분리된 공간인 증발기실(103)에 설치되며, 증발기(40)에 의해 냉각된 공기는 증발기실(103)에 설치된 송풍팬(50)의 작동으로 냉동, 냉장실로 유입 순환됨으로써 냉동실(101) 및 냉장실(102)의 온도가 낮아지게 된다.In such a refrigerator, the low-temperature low-pressure gaseous refrigerant is compressed to high temperature and high pressure by the compressor 20, and the compressed high-temperature high-pressure gas phase refrigerant is cooled and condensed while passing through the condenser 30 to be converted into a high-pressure liquid phase, and the high-pressure liquid The refrigerant in the state passes through a capillary tube (not shown), and its temperature and pressure are lowered. Then, the refrigerant is changed into a gaseous state of low temperature and low pressure in the evaporator 40 to take heat from the surroundings to cool the air around it. The evaporator 40 is installed in the evaporator chamber 103, which is a separate space behind the freezing chamber 101, and the air cooled by the evaporator 40 is operated by the blower fan 50 installed in the evaporator chamber 103. As the freezing and refrigerating chamber are introduced and circulated, the temperatures of the freezing chamber 101 and the refrigerating chamber 102 are lowered.
한편, 냉장고에 적용되는 일반적인 증발기는 금속재로서 도 2에 나타난 것과 같이 ‘ ?? ' 형태로 연속 벤딩(bending)되어 일종의 다중겹 형상으로 이루어진 냉매관(42)과, 일정한 간격을 두고 다수개가 평행하게 배열되어 용접에 의해 냉매관(42)에 부착되며, 외견상 벤딩된 냉매관(42)을 가로지르는 형태로 장착되는 얇은 패널형태의 전열핀(44)으로 구성되는 핀 튜브형이 주로 사용된다.Meanwhile, a general evaporator applied to the refrigerator is a metal material, as shown in FIG. Coolant pipe 42 which is continuously bent in a shape to form a kind of multi-ply shape and a plurality of parallelly arranged at regular intervals and attached to the coolant pipe 42 by welding, A fin tube type consisting mainly of heat-transfer fins 44 in the form of a thin panel mounted in the form of crossing the 42 is mainly used.
상기 금속재의 핀튜브형 증발기(40)는 냉매관(42)과 냉각핀(44)을 비롯한 각 구성요소의 재질적인 특성상 다양한 형상으로 제작하기 어렵고, 부피에 비해 무겁다는 단점을 가지고 있다.The fin tube-type evaporator 40 of the metal material is difficult to manufacture in various shapes due to the material properties of each component, including the refrigerant pipe 42 and the cooling fin 44, and has a disadvantage in that it is heavy compared to the volume.
이와 같은 종래 금속재 증발기의 문제점을 해결하기 위하여 플라스틱 재질의 증발기가 개발되었는데, 종래 플라스틱 증발기는 도 3에 나타난 것과 같이 냉매가 흐르는 다수개의 냉매관부(461)와, 상기 냉매관부(461)들을 연결하는 냉각핀부(462)가 일체로 형성된 이른바 열교환시트(46)를 단위구성요소로 하여 구성되며, 도 4에 나타난 것과 같이 상기 열교환시트(46)가 다수개 중첩 배열된 구조로 이루어진다.In order to solve the problems of the conventional metal evaporator, a plastic evaporator has been developed. The conventional plastic evaporator connects the plurality of refrigerant pipe parts 461 and the refrigerant pipe parts 461 through which a refrigerant flows, as shown in FIG. 3. The so-called heat exchange sheet 46 formed integrally with the cooling fins 462 is configured as a unit component, and as shown in FIG. 4, the heat exchange sheet 46 has a plurality of overlapping arrangements.
상기 플라스틱 증발기는 구조가 간단하고, 부피에 비해 무게가 가볍기 때문에 종래 금속재 증발기에 비해 냉장고의 상품성 향상에 도움이 된다/The plastic evaporator is simple in structure and light in weight compared to the volume, thus improving the commercialization of the refrigerator compared to the conventional metal evaporator.
그러나, 상술한 바와 같은 플라스틱 증발기는 종래 금속재 증발기와 마찬가지로 냉동실(101) 후면의 증발기실(103)에 설치되며, 금속재 증발기와 거의 동일한 체적으로 구성됨으로써 냉장고의 수납공간이 감소되는 한 원인이 되었다However, the plastic evaporator as described above is installed in the evaporator chamber 103 at the rear of the freezing chamber 101 similarly to the conventional metal evaporator, and is composed of almost the same volume as the metal evaporator, thereby causing a decrease in the storage space of the refrigerator.
본 발명은 상기한 종래 문제점을 해결하고자 안출된 것으로서, 열교환 및 단열벽 기능을 동시에 수행하는 플라스틱 증발기를 구비함으로써 수납공간이 확대되는 등, 상품성이 향상되는 냉장고에 관한 것이다.The present invention has been made to solve the above-mentioned conventional problems, and relates to a refrigerator having improved merchandise, such as an enlarged storage space, by providing a plastic evaporator that simultaneously performs heat exchange and heat insulating wall functions.

본 발명의 실시예에 따른 냉장고는 플라스틱 재질의 증발기를 포함하여 구성되는데, 도 5에 나타난 것과 같이 상기 플라스틱 증발기(60)는 냉매가 흐르는 다수개의 냉매관부(62)와 상기 냉매관부(62)들을 연결하는 냉각핀부(64)로 구성된 단일패널 구조로서, 냉동실(101)의 후면과 측면을 둘러쌀 수 있도록(도 6 참조) 절곡된 형태로 이루어진다.The refrigerator according to the embodiment of the present invention includes a plastic material evaporator, and as shown in FIG. 5, the plastic evaporator 60 includes a plurality of refrigerant pipe parts 62 and the refrigerant pipe parts 62 through which refrigerant flows. As a single panel structure consisting of the cooling fins 64 to be connected, it is formed in a bent form so as to surround the rear and side surfaces of the freezing compartment 101 (see FIG. 6).
한편, 본 실시예에 따른 플라스틱 증발기는 종단면 구조상 재질적으로 열전도율이 다른 내측면부(도면상 선단면 표시)와 외측면부(도면상 점단면 표시)가 조합된 구조로 이루어지는데, 상기 내측면부는 냉동실(101)의 수납공간으로 노출되는 부분으로서 열전도율이 높은 재질로 이루어지며, 외측면부는 열전도율이 낮은 재질로 이루어진다.On the other hand, the plastic evaporator according to the present embodiment has a structure in which the inner surface portion (shown in the front end face on the drawing) and the outer side portion (shown in the point cross section on the drawing) in which the thermal conductivity differs in material in the longitudinal cross-sectional structure, the inner surface portion freezer compartment A portion exposed to the storage space of 101 is made of a material having a high thermal conductivity, the outer surface portion is made of a material having a low thermal conductivity.
