본 고안은 냉장고용 소형도어의 열전도 차단구조, 더욱 상세하게는 냉장고의 냉장실도어의 부분적으로 설치되어 있는 소형도어의 결합부를 통해 발생되는 냉기의 손실을 방지 할 수 있게한 냉장고용 소형도어의 열전도 차단구조에 관한 것이다.The present invention provides a heat conduction blocking structure of a small door for a refrigerator, and more specifically, a heat conduction blocking of a small door for a refrigerator, which can prevent loss of cold air generated through a coupling part of a small door installed partially of a refrigerator door of a refrigerator. It's about structure.

일반적으로, 냉장실에 보관된 식품, 예를 들어 물이나 음료수등을 빈번하게 넣고 꺼낼때 발생되는 냉기의 손실을 줄일 목적으로 제1도에서와 같이 냉장실도어(10)의 적당위치에 소형도어(20)를 설치한 냉장고가 보편화 되어있다.In general, a small door 20 at a suitable position of the refrigerating chamber door 10 as shown in FIG. 1 for the purpose of reducing the loss of cold air generated when the food, for example, water or beverage, etc., frequently stored in the refrigerating chamber is removed. ) Refrigerators are common.

즉, 냉장실의 일부분을 사용함에도 냉장실도어(10)를 전체적으로 열게됨으로써, 불필요한 냉기의 손실과 사용상의 불편이 발생하였고, 이때 발생되는 문제점을 해소할 목적으로 소형도어(20)를 설치하였다.That is, even when using a part of the refrigerating chamber by opening the refrigerating chamber door 10 as a whole, unnecessary loss of cold air and inconvenience in use occurred, the small door 20 was installed for the purpose of solving the problems caused at this time.

제2도는 종래의 소형도어의 밀폐상태를 나타낸 것으로, 이 소형도어(20)는 내·외측 케이스(21)(22)를 일체로 형합한 공간에 발포물로된 단열층(23)을 형성한 구조로 되고, 소형도어의 밀폐시 이의 가장자리 부분이 밀착되는 도어몸체(11)의 접촉부에 기밀작용을 하는 가스켓(13)과 고내외의 온도차를 감소시켜주는 히트파이프(12)를 각각 착설하였다.2 shows a closed state of a conventional small door. The small door 20 has a structure in which a heat insulation layer 23 made of foam is formed in a space in which the inner and outer cases 21 and 22 are integrally formed. When the small door is closed, a gasket 13 for airtightness and a heat pipe 12 for reducing the temperature difference between the inside and the outside of the door body 11 are closely installed.

상기 구조는 소형도어(20)의 내측케이스(21)에 가해지는 냉기온도가 외부의 더운공기의 영향을 받는 외부케이스(22)와 직접 전도되는 과정에서 그 형합부에 과다한 온도편차로 인하여 결로가 발생되는 문제점이 있었다.The structure has condensation due to excessive temperature deviation in the fitting part in the process of directly conducting the cold air temperature applied to the inner case 21 of the small door 20 to the outer case 22 affected by the external hot air. There was a problem that occurred.

또한, 상기 결로현상을 제거하기 위해 도어몸체(11)의 내측에 히트파이프(12)를 배관하였으므로, 구조가 복잡하였음은 물론 이 히트파이프의 동작에 따른 전력소모가 증가되는 비경제적인 결점도 있었다.In addition, since the heat pipe 12 was piped to the inside of the door body 11 to remove the condensation phenomenon, the structure was complicated and there was also an uneconomical disadvantage in that power consumption increased due to the operation of the heat pipe.

본 고안은 위와 같은 종래의 냉장고용 소형도어의 문제점을 감안하여 안출한 것으로서, 그 목적은 고내외의 온도 편차로 인한 결로를 방지하는 냉장고용 소형도어의 열전도 차단구조를 제공하는 것이다.The present invention has been made in view of the problems of the conventional small door for the refrigerator as described above, the object is to provide a heat conduction blocking structure of the small door for the refrigerator to prevent condensation due to the temperature deviation of the inside and outside.

본 고안의 다른 목적은, 고내에서 외부로 전도되는 냉기를 간단한 구조로 분산시키고 밀폐력을 향상시킬 수 있는 냉장고용 소형도어의 열전도 차단구조를 제공함에 있다.Another object of the present invention is to provide a heat conduction blocking structure of a small door for a refrigerator that can disperse the cold air conducted from the inside to the outside in a simple structure and improve the sealing force.

이러한 본 고안의 목적은, 소형도어의 내외측케이스의 연결부위에 간극을 형성한 후 이에 영구자석이 내장된 가스켓을 삽입설치하여 도어몸체에 밀착되게 하고, 이 도어몸체의 내측에 금속으로 된 열분산판을 설치함으로써 달성된다.The purpose of the present invention is to form a gap in the connection part of the inner and outer cases of the small door, and then insert a gasket with a permanent magnet therein to be in close contact with the door body, and the heat of the metal inside the door body This is achieved by installing a plate.

즉, 저온이 전도되는 내측케이스와 실내의 고온이 전도되는 외측케이스가 간극에 의해 분리되어 있고 이에 비전도체로된 가스켓이 삽입되어 있으므로, 그 구조적인 작용에 의해 열의 전도가 차단된다.That is, since the inner case where the low temperature is conducted and the outer case where the high temperature is conducted in the room are separated by a gap and a gasket made of a non-conductor is inserted therein, conduction of heat is blocked by its structural action.

한편, 도어몸체로부터 전도되는 열은 그 내측에 설치된 열전도성이 높은 금속재의 열분산판에 의해 흡수되어 분산되므로 간단한 구조로 결로현상이 방지됨을 특징으로 한다.On the other hand, the heat conducting from the door body is absorbed and dispersed by the heat dissipation plate of the high thermal conductivity metal material installed in the inside is characterized in that the condensation phenomenon is prevented by a simple structure.

이하, 본 고안의 냉장고용 소형도어의 열전도 차단구조를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, the heat conduction blocking structure of the small door for a refrigerator of the present invention will be described in detail with reference to the accompanying drawings.

제3도는 본 고안의 실시예의 소형도어의 밀폐상태를 나타낸 것으로서, 도어몸체(100)의 적정 위치에 형성된 개구부(110)에 소형도어(200)가 개폐가능하게 설치되어, 이 소형도어를 사용함으로써 냉긱의 손실을 줄이고 냉장고의 사용을 편리하게 하였음은 위에서 설명한 바와 같다.3 is a view illustrating a closed state of a small door according to an embodiment of the present invention, and the small door 200 is installed to be opened and closed at an opening 110 formed at an appropriate position of the door body 100, thereby using the small door. As described above, the loss of cold gig and ease of use of the refrigerator are facilitated.

상기 소형도어(200)는 고내에 위치되는 내측케이스(210)와 외부에 위치되는 외측케이스(220)를 간극(230)이 유지되게 형합하여 이 간극에 가스켓(240)을 착설하고 상기 양측케이스(210)(220)에 의해 구비된 내부공간에 단열층(250)을 형성한 구조로 되어 있다.The small door 200 forms a gasket 240 in the gap between the inner case 210 and the outer case 220 positioned in the refrigerator to maintain the gap 230 so as to install the gasket 240 in the gap. The heat insulation layer 250 is formed in the internal space provided by the 210 and 220.

상기 가스켓(240)은 도어몸체(100)의 개구부(110)에 착설한 프레임(120)에 적어도 어느 한편이 밀착되며, 가스켓(240)의 내측에는 영구자석(300)이 내장되어 있다.At least one of the gaskets 240 is in close contact with the frame 120 mounted on the opening 110 of the door body 100, and a permanent magnet 300 is embedded inside the gasket 240.

가스켓(240)이 밀착되는 프레임(120)의 내측부위에는 상기 영구자석(300)의 자력에 상응하는 자성체(310)가 설치되며, 도어몸체(100)의 내외부에서 전도되는 온도의 영향이 집중되는 부위의 프레임(120)의 내측에 전도열을 분산시키는 유도판(400)이 부설되어 있다.A magnetic body 310 corresponding to the magnetic force of the permanent magnet 300 is installed at the inner portion of the frame 120 in which the gasket 240 is in close contact, and the portion at which the influence of temperature conducted from inside and outside the door body 100 is concentrated is concentrated. An induction plate 400 is disposed inside the frame 120 to dissipate the conductive heat.

이 유도판(400)은 열전도성이 양호한 비철금속재가 바람직하다.The induction plate 400 is preferably a nonferrous metal having good thermal conductivity.

냉장고의 구동시 소형도어(200)가 설치된 부위의 고내온도가 -5℃이고 외부온도가 20℃일 경우, 그 온도편차는 25℃이므로, 소형도어(200)를 구성하는 내·외측케이스(210)(220)는 서로 상이한 온도가 전도되며, 상기 소형도어에 비해 단열효과가 양호한 도어몸체(100)의 프레임(120)에도 고내외의 온도편차가 발생된다.When the internal temperature of the site where the small door 200 is installed is -5 ° C. and the external temperature is 20 ° C. when the refrigerator is driven, the temperature deviation is 25 ° C., so that the inner and outer cases constituting the small door 200 are 210. 220 is conducting different temperatures to each other, the temperature deviation of the inside and outside of the frame 120 of the door body 100 has a better thermal insulation effect than the small door.

이때, 소형도어(200)의 내·외측케이스(210)(220)에서 각각 전도되는 온도는 그 형합 과정에서 형성된 간극(230)에 의해 열의 상호교환이 1차적으로 차단되고, 간극(230)에 착설한 가스켓(240)에 의해 2차적인 열차단이 이루어 지게되어, 열전도가 거의 발생되지 않는다.At this time, the temperature conducted at each of the inner and outer cases 210 and 220 of the small door 200 is primarily blocked by the gap 230 formed during the molding process, and the gap 230 is interposed therebetween. Secondary thermal cut-off is achieved by the installed gasket 240, so that little heat conduction occurs.

한편, 도어몸체(100)의 개구부(110)에 착설된 프레임(120)을 통해 그 내외측에서 전도되어 상호교환되는 열은 프레임의 내측에 착설된 유도판(400)에 전도되어 분산된다.On the other hand, through the frame 120 installed in the opening 110 of the door body 100, the heat is exchanged in and out of the inside and is exchanged by the guide plate 400 installed on the inside of the frame is dispersed.

상기 열차단 및 분산작용에 의해 온도창 취약한 소형도어(200)에 가장자리와 이에 인접된 도어몸체(100)에 발생되는 결로현상이 방지된다.Due to the heat shielding and dispersing action, condensation occurring on the edge and the door body 100 adjacent to the small door 200 having a weak temperature window is prevented.

또한, 소형도어(200)의 밀폐시 이에 착설된 가스켓(240)이 개구부(110)에 착설된 프레임(120)에 밀착됨과 아울러, 가스켓(240)에 내장된 영구자석(300)이 프레임(120)을 사이에 두고 설치한 자성체(310)에 자기력을 가하게 되어 더욱 긴밀한 상태로 소형도어를 밀폐시키는 작용을 한다.In addition, when the small door 200 is closed, the gasket 240 installed thereon is in close contact with the frame 120 installed in the opening 110, and the permanent magnet 300 embedded in the gasket 240 is frame 120. The magnetic force is applied to the magnetic body 310 installed with the gap between them to close the small door in a more intimate state.

이와 같은 본 고안은 고내·외에서 전도되는 열을 정확하게 차단하고 소형도어의 밀폐력을 향상시킬 수 있는 효과가 있으며, 상기 작용에 의해 냉기의 손실을 방지하여 절전효과를 얻을 수 있는 장점도 있다.The present invention has the effect of accurately blocking heat conducted inside and outside the high and improve the sealing force of the small door, and also has the advantage of preventing the loss of cold air by the above action to obtain a power saving effect.
