도 1은 본 발명에 따른 냉장고를 개략적으로 나타내 보인 단면도,1 is a cross-sectional view schematically showing a refrigerator according to the present invention,

도 2는 본 발명에 따른 냉장고용 댐퍼 유니트를 발췌하여 도시한 사시도,2 is a perspective view showing an extractor damper unit for a refrigerator according to the present invention;

도 3은 본 발명에 따른 댐퍼 유니트의 다른 실시예를 도시한 분리 사시도. Figure 3 is an exploded perspective view showing another embodiment of the damper unit according to the present invention.

본 발명은 냉장고에 관한 것으로, 더 상세하게는 냉장실 또는 냉동실에 증발기로부터 발생된 냉기의 공급을 단속하기 위한 냉장고의 댐퍼 유니트에 관한 것이다. The present invention relates to a refrigerator, and more particularly, to a damper unit of a refrigerator for controlling the supply of cold air generated from an evaporator to a refrigerator compartment or a freezer compartment.

일반적으로 냉장고는 냉동실(F)과 냉장실(R)이 상/하로 구획 된 탑 마운트 타입(Top Mount-Type)과, 냉장실(R)과 냉동실(F)이 상/하로 구획된 바텀 프리져 타입(Bottom Freezer-Type)과, 냉동실(F)과 냉장실(R)이 좌/우측으로 구획된 사이드 바이 사이드 타입(Side By Side-Type)으로 나뉘어진다. Generally, the refrigerator has a top mount type in which the freezer compartment (F) and the refrigerator compartment (R) are divided up and down, and a bottom freezer type in which the refrigerator compartment (R) and the freezer compartment (F) is divided up and down ( Bottom Freezer-Type), and Freezer (F) and Refrigerator (R) are divided into Side By Side-Types (left and right).

상기와 같은 냉장고들은 증발기에 의해 저온 저압의 기상상태로 상변화 된 냉매가 압축기에 의해 저온 저압에서 고온 고압으로 압축되고, 상기 압축된 고온 고압의 기상 냉매는 응축기를 지나는 과정에서 냉각 응축되어 고압의 액상 상태로 상변화 된다. 상기와 같이 고압의 액상상태로 상변화 된 냉매는 팽창밸브를 통과하여 상기 증발기 내에서 단열팽창 됨으로써 주위의 열을 흡수한 후 압축기로 유입된다. 이 때, 상기 증발기와의 열교환을 통해 냉각된 공기(냉기)는 송풍기와 댐퍼 유니트에 의해 냉동실과 냉장실로 공급된다.In the refrigerators as described above, the refrigerant which is phase-changed into a low temperature low pressure gas phase by an evaporator is compressed from a low temperature low pressure to a high temperature high pressure by a compressor, and the compressed high temperature high pressure gas phase refrigerant is cooled and condensed in the course of passing through a condenser. Phase change to liquid phase. As described above, the refrigerant changed into a high-pressure liquid state passes through an expansion valve and is adiabaticly expanded in the evaporator to absorb ambient heat and then flows into the compressor. At this time, the air (cold air) cooled through heat exchange with the evaporator is supplied to the freezer compartment and the refrigerating compartment by a blower and a damper unit.

증발기로부터 냉장실로 공급되는 냉기의 공급량을 제어하기 위한 댐퍼는 댐퍼커버와, 이 댐퍼커버의 내측에 설치되어 댐퍼커버를 지지함과 아울러 단열을 위한 단열부재와, 냉기를 냉장실과 냉동실로의 공급을 제어하기 위한 수단을 구비한다. 이 단열부재와 댐퍼커버는 냉기 유로와 냉기 유출구가 형성된다. The damper for controlling the supply amount of cold air supplied from the evaporator to the refrigerating chamber is provided with a damper cover and an inner side of the damper cover to support the damper cover, and to provide insulation to the refrigerator and the freezer compartment. Means for controlling. The heat insulating member and the damper cover are provided with a cold air passage and a cold air outlet.

상기 댐퍼의 단열부재는 통상적으로 이 피 에스(EPS; Expanded polystyrene)로 제작된다. 이와 같이 제작된 단열부재는 장기간 사용시 결로 현상에 의한 수분을 흡수하게 되어 악취가 발생의 원인이 되며, 결로에 의한 수분은 냉기를 공급하기 위한 수단 즉, 냉기 유출구를 개폐하기 위한 도어와 이를 구동시키기 위한 구동부의 고장원인이 된다. 특히 단열부재에 흡수된 수분은 냉기에 의해 성애의 발생원인이 되고 나아가서는 이 성애에 의해 덕트의 역할을 수행 할 수 없게 된다. 또한 상기 단열부재는 구조적으로 약하여 댐퍼커버에 별도의 고정수단 없이 직접 고정하기 어려기 때문에 댐퍼커버에 대해 단열재를 고정하기 위한 별도의 수단이 필요하다. 이 수단은 댐퍼커버와 결합되어 단열재를 감싸는 금속 플레이트가 이용되고 있는데, 상기 금속 플레이트에 결로 현상의 발생되는 것을 방지하기 위하여 별도의 단열시트가 부착하고 있다. 이와 같이 댐퍼커버에 단열부재를 고정하기 위하여 수단과 단열시트를 부착하는 것은 댐퍼의 생산원가 상승원인이 된다. The heat insulating member of the damper is typically made of expanded polystyrene (EPS). The heat insulating member manufactured as described above absorbs moisture due to condensation when used for a long period of time, causing odor. The moisture caused by condensation is a means for supplying cold air, that is, a door for opening and closing a cold air outlet and driving the same. It is the cause of failure of driving part. In particular, the moisture absorbed by the heat insulating member is the cause of the frost caused by the cold air, and furthermore, the frost cannot serve as a duct. In addition, since the heat insulating member is structurally weak and difficult to directly fix to the damper cover without a separate fixing means, a separate means for fixing the heat insulating material to the damper cover is required. This means is used in combination with a damper cover to cover a heat insulating material, a metal plate, which is attached to a separate heat insulating sheet to prevent the occurrence of condensation on the metal plate. As such, attaching the means and the insulation sheet to fix the insulation member to the damper cover is a cause of the increase in the production cost of the damper.

It includes a damper unit 20 installed to be.

이러한 댐퍼 유니트(20)는 도 1 및 도 2에 도시된 바와 같이 상기 송풍기(30)의 송풍력에 의해 공급된 냉기를 받아 흐름을 안내함과 동시에 그 냉기를 상기 냉동실(1), 냉장실(2), 야채실(미도시) 내에 골고루 확산 분출시키도록 냉장실 후 측의 본체에 설치되는 댐퍼커버(21)와, 증발기(5)에서 열교환된 냉기가 냉장실(1) 및 야채실 내에 공급될 때 그 냉기의 공급량을 조절하는 댐퍼수단을 구비한다. 이 댐퍼수단은 도면에는 도시되어 있지 않으나 냉장고의 냉장실, 야채실의 내부로 냉기의 공급량을 조절하는 댐퍼부재(냉기의 배출구를 개폐하기 위한 도어)와, 이 댐퍼부재를 구동시키기 위한 구동부를 구비한다. 한편, 상기 댐퍼커버(21)의 재질은 ABS(Acrylonitrile Butadiene Styrene), HIPS(High Impact Polystyrene), PP(Polypropylene)중 선택된 하나의 수지를 사용함이 바람직하다. As shown in FIGS. 1 and 2, the damper unit 20 receives the cool air supplied by the blowing force of the blower 30 to guide the flow and simultaneously cools the cold air in the freezer compartment 1 and the refrigerating compartment 2. ), The damper cover 21 installed in the main body on the side of the refrigerating compartment so as to evenly spread and eject in the vegetable compartment (not shown), and when the cold air exchanged from the evaporator 5 is supplied into the refrigerating compartment 1 and the vegetable compartment. Damper means for adjusting the supply amount is provided. Although not shown in the drawing, the damper means includes a damper member (a door for opening and closing the outlet of the cold air) for controlling the supply amount of cold air into the refrigerating chamber and the vegetable compartment of the refrigerator, and a driving unit for driving the damper member. On the other hand, the damper cover 21 is preferably made of one resin selected from ABS (Acrylonitrile Butadiene Styrene), HIPS (High Impact Polystyrene), PP (Polypropylene).

그리고 상기 댐퍼커버(21)에는 단열부재가 설치되어 노점온도 이하에서 결로 현상이 발생되거나 이 결로현상에 의한 성애의 발생을 방지하기 위한 단열부재(22)가 설치된다. 이러한 단열부재(22)는 댐퍼커버(21)에 형성된 배출구(21a)와 대응되는 측 개구부(22a)들이 형성됨과 아울러 댐퍼 커버(21)와 결합되어 냉기를 공급할 수 있도록 냉기통로(22b)가 형성된다. In addition, the damper cover 21 is provided with a heat insulating member is provided with a heat insulating member 22 for preventing condensation from occurring or dew condensation occurs below the dew point temperature. The heat insulating member 22 is formed with side openings 22a corresponding to the outlet 21a formed in the damper cover 21, and a cold air passage 22b is formed to be combined with the damper cover 21 to supply cold air. do.

이러한 단열부재(22)는 EPP(expanded polypropylene)로 이루어진다. 상기와 같은 형상을 가지는 단열부재(22)는 성형몰드의 성형공간에 EPP를 주입하고 스팀을 이용하여 가열함으로써 성형하고, 성형이 완료된 단열부재(22)를 성형공간에 장착된 상태에서 진공분위기에서 물을 이용하여 냉각시킨다. 그리고 성형몰드로부터 성형이 완료된 단열부재(22)를 분리하고 이를 소정의 온도에서 숙성시킨다.The heat insulating member 22 is made of expanded polypropylene (EPP). The heat insulating member 22 having the shape as described above is molded by injecting EPP into the molding space of the molding mold and heating by using steam, and in the vacuum atmosphere in which the insulating member 22 is completed in the molding space. Cool with water. Then, the insulating member 22, which has been molded, is separated from the molding mold and aged at a predetermined temperature.

한편, 상기와 같이 단열부재를 성형하는 과정에서 상기 단열부재를 댐퍼커버(21)에 고정하기 위한 고정브라켓(23)을 인서트 몰딩 할 수 있다. 상기 단열부재는 EPP로 형성되어 구조적 강도가 높아 인서트 몰딩된 브라켓이 단열부재(22)로부터 분리되는 것을 방지할 수 있다. On the other hand, in the process of molding the heat insulating member as described above it can insert molding the fixing bracket 23 for fixing the heat insulating member to the damper cover 21. The insulation member is formed of EPP to prevent the insert molded bracket from being separated from the insulation member 22 due to high structural strength.

도 3에는 댐퍼 유니트의 다른 실시예를 나타내 보였다. 댐퍼 커버(21)에 단열부재(22)가 결합된 상태를 보여준다. 3 shows another embodiment of a damper unit. Shows a state in which the heat insulating member 22 is coupled to the damper cover 21.

상기와 같이 구성된 냉장고용 댐퍼 유니트(20)는 냉장고의 구동으로 증발기가 냉각되면, 이 냉기가 댐퍼 유니트(20)에 의해 안내된 후 댐퍼수단에 의해 선택적으로 배출구를 통하여 냉동실(1)과 냉장실(2)에 공급된다.When the evaporator is cooled by the operation of the refrigerator, the damper unit for refrigerator 20 configured as described above is guided by the damper unit 20, and then the freezer compartment 1 and the refrigerating compartment (1) through a discharge port selectively by a damper means ( 2) is supplied.

이 과정에서 상기 냉동실 또는 내장실 내의 공기는 증발기를 통과하는 과정에서 냉각되면서 제습이 이루어지나 냉동 또는 냉장실 내의 음식물로부터 증발하 는 수분을 함유하고 있다. 따라서 댐퍼 유니트(20)를 통하여 냉기가 공급되는 과정에서 냉장실 내의 온도와 냉기의 온도차이에 의해 댐퍼 유니트 즉, 댐퍼커버(21) 및 이의 배출구와 단열부재(22)의 표면에 결로가 발생된다. 상기 단열부재(22)의 표면에 부착된 수분은 시간이 경과하여도 단열부재(22)가 EPP로 이루어져 있으므로 함습 되지 않게 된다. 따라서 결로 제거를 위한 댐퍼의 결상 해소용 히터에 의해 수분이 완전히 제거될 수 있으며, 나아가서는 종래와 같이 단열부재에 수분이 함습 됨으로써 발생되는 성애 또는 수분의 동결로 인하여 구동부를 가지는 댐퍼수단이 손상되는 것을 근본적으로 방지할 수 있다. In this process, air in the freezing compartment or internal compartment is dehumidified while being cooled in the course of passing through an evaporator, but contains moisture that evaporates from food in the freezing or refrigerating compartment. Therefore, condensation is generated on the surface of the damper unit, that is, the damper cover 21, its outlet, and the heat insulating member 22 by the temperature difference between the temperature in the refrigerating chamber and the cold air in the process of supplying the cold air through the damper unit 20. Moisture attached to the surface of the heat insulating member 22 is not impregnated because the heat insulating member 22 is made of EPP even if time passes. Therefore, moisture can be completely removed by the heater for removing the phase of the damper for removing dew condensation. Further, the damper means having the driving part is damaged due to freezing of the sex or moisture generated by moisture in the heat insulating member as in the prior art. Can fundamentally prevent things.

그리고 상기 단열부재(22)에는 이를 고정하기 위한 고정브라켓(23)이 인서트 몰딩 되어 있으므로 단열부재의 고정을 위하여 별도의 결합수단이 불필요하게 되며 종래와 같이 고정을 위한 패널에 결로가 발생되는 것을 방지하여 위하여 별도의 단열시트를 부착할 필요가 없다. And since the fixing bracket 23 for inserting the fixing member 23 is inserted in the heat insulating member 22, a separate coupling means is unnecessary for fixing the heat insulating member, and condensation is prevented from occurring in the panel for fixing as in the prior art. There is no need to attach a separate insulation sheet.

이상에서 설명한 바와 같이 본 발명에 따른 냉장고용 댐퍼 유니트는 댐퍼커버의 내측에 설치되는 단열부재가 수분이 함습되는 것을 근본적으로 방지할 수 있으며, 댐퍼유니트의 통로에 결로 또는 성애의 발생으로 댐퍼수단이 손상되는 것을 근본적으로 방지할 수 있다. As described above, the damper unit for a refrigerator according to the present invention may fundamentally prevent moisture from being insulated from the heat insulating member installed inside the damper cover, and the damper means may be formed by condensation or frost in the passage of the damper unit. It can fundamentally prevent damage.

본 발명은 도면에 도시된 일 실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 당해 기술 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 실시예가 가능하다는 점을 이해할 것이다.Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible.

따라서 본 발명의 진정한 보호 범위는 첨부된 청구범위에 의해서만 정해져야 할 것이다. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
