Description
본 발명은 냉각 장치에 관한 것으로, 무동결 장치를 구비하는 냉각 장치에 관한 것이다. 더욱 상세하게는 기존의 냉장고와 같은 냉각 장치의 구성을 크게 변경하지 않고, 냉각 장치 내에 구비되어 식품 및 음료를 무동결 상태로 보관할 수 있고, 특히 음료의 경우 용이하게 슬러시를 제조할 수 있는 냉각 장치에 관한 이다. The present invention relates to a cooling device, and to a cooling device having a non-freezing device. More specifically, the cooling device which is provided in the cooling device to store food and beverages in a freeze-free state without particularly changing the configuration of a cooling device such as a conventional refrigerator, and in particular, in the case of a beverage, can easily prepare slush. Is about.
과냉각이란, 용융체 또는 고체가 평형상태에서의 상전이 온도 이하까지 냉각되어도 변화를 일으키지 않는 현상을 의미한다. 물질에는 각각 그때의 온도에 따른 안정상태가 있어서, 온도를 서서히 변화시켜 가면 이에 따라 그 물질의 구성원자가 각 온도에서 안정상태를 유지하면서 온도의 변화를 따라갈 수가 있다. 그러나 온도가 갑자기 변하면 구성원자가 각 온도에 따른 안정상태로 변화할 만한 여유가 없기 때문에, 출발점 온도에서의 안정상태를 그대로 지니거나, 또는 일부분이 종점 온도에서의 상태로 변화하다가 마는 현상이 일어난다. Subcooling means a phenomenon that no change occurs even when the melt or solid is cooled to below the phase transition temperature at equilibrium. Each substance has a stable state corresponding to the temperature at that time, so that the temperature can be gradually changed so that members of the substance can keep up with the temperature change while maintaining the stable state at each temperature. However, if the temperature suddenly changes, the member cannot afford to change to the stable state according to each temperature, so that the state remains stable at the starting point temperature, or a portion thereof changes to the state at the end point temperature.
예를 들어, 물을 서서히 냉각하면, 0℃ 이하의 온도가 되어도 일시적으로 응고하지 않는다. 그러나, 물체가 과냉각상태로 되면 일종의 준안정 상태가 되어, 사소한 자극에 의해서도 그 불안정한 평형상태가 깨져서 보다 안정된 상태로 옮아가기 쉽다. 즉, 과냉각된 액체에 그 물질의 작은 조각을 투입하거나, 액체를 갑자기 흔들면 즉시 응고하기 시작하여 액체의 온도가 응고점까지 올라가고, 그 온도에서 안정된 평형상태를 유지하게 된다. For example, if water is gradually cooled, it will not temporarily solidify even if it reaches a temperature of 0 ° C or lower. However, when the object is in the supercooled state, it becomes a kind of metastable state, and the unstable equilibrium state is broken even by a slight stimulus, and it is easy to move to a more stable state. That is, when a small piece of material is added to the supercooled liquid or the liquid is suddenly shaken, the liquid starts to solidify immediately and the temperature of the liquid rises to the freezing point, thereby maintaining a stable equilibrium at that temperature.

승압트랜스(17)의 2차측 출력의 일단(O1)은 고압 케이블(4)을 통해 보냉고로부터 절연되어 있는 금속선반(7)에 접속되고, 출력의 타단(O2)는 어스된다. 또, 외벽(5)은 어스되므로, 보냉고(1)의 사용자가 보냉고의 외벽에 접촉해도 감전되는 것이 아니다. 또, 금속선반(7)은 도 1에서는 고내에서 노출되어 있으면,금속선반(7)은 고내에서 절연상태로 유지될 필요가 있으므로, 고내 벽으로부터 이간시킬 필요가 있다(공기가 절연작용을 함). 또, 금속선반(7)으로부터 대상물(8)이 돌출하여 고내 벽에 접하면 전류가 고벽을 통해 그라운드로 흐르므로, 상기 절연판(2a)을 내벽에 붙이면 인가되는 전압의 드롭이 방지된다. 그리고, 상기 금속선반(7)을 고내에서 노출시키지 않고 염화 비닐재 등으로 피복해도 고내 전체가 전장 분위기로 된다. One end O 1 of the secondary output of the boosting transformer 17 is connected to the metal shelf 7 insulated from the cold storage via the high voltage cable 4, and the other end O 2 of the output is earthed. Moreover, since the outer wall 5 is earthed, even if the user of the cold storage 1 contacts the outer wall of the cold storage, electric shock will not occur. In addition, if the metal shelf 7 is exposed in the furnace in FIG. 1, since the metal shelf 7 needs to be kept insulated in the furnace, it is necessary to separate it from the walls of the furnace (air acts as an insulation). . In addition, when the object 8 protrudes from the metal shelf 7 and contacts the inner wall, current flows to the ground through the high wall. Therefore, when the insulating plate 2a is attached to the inner wall, the drop of applied voltage is prevented. And even if the said metal shelf 7 is coat | covered with vinyl chloride material etc. without exposing in the inside, the whole inside of an interior becomes an electric field atmosphere.

High power consumption is required for the generation of such electric or magnetic fields. In addition, such a device for generating an electric field or a magnetic field is additionally provided with a device (for example, an electric field or magnetic field shielding structure, a blocking device, etc.) for the safety of the user when the electric field or the magnetic field is generated, when the electric field or magnetic field is generated due to the high power. Should be.
일본 특허 공개공보 특개 2001-4260에는 개폐 가능한 단열고 내에 온도 검지수단과 고내를 소정의 온도 설정치로 제어하는 제어 수단을 가지고 과냉각 운전 시에 동결점 이하의 온도에서 보관품을 냉장 보관할 수 있는 과냉각 제어 냉장고를 개시하고 있다. 그러나 단순히 냉기 순환 팬의 회전수를 제어하여 단열고 내의 온도를 조절하며, 고내의 온도가 설정치 이하로 떨어지는 경우 단시간에 설정치로 온도를 다시 올릴 수 있는 수단이 없다. 따라서 고내의 온도가 설정치 이하로 떨어진 상태로 시간이 경과하는 경우 과냉각 상태로 저장하고자 한 보관품이 동결되는 경우가 많고, 또한 동결된 보관품을 해동하여 다시 과냉각 상태로 저장할 수도 없어 무동결 상태를 유지하는 안정성이 떨어진다는 문제점이 있다.Japanese Patent Laid-Open No. 2001-4260 has a supercooling control that can refrigerate the stored product at a temperature below the freezing point during subcooling operation with a temperature detecting means and a control means for controlling the inside of the insulated open-air storage to a predetermined temperature set point. The refrigerator is starting. However, by simply controlling the rotation speed of the cold air circulation fan to adjust the temperature in the insulation chamber, there is no means to raise the temperature back to the set point in a short time when the temperature in the store drops below the set point. Therefore, when the time elapses while the temperature in the refrigerator drops below the set value, the storage items to be stored in the supercooled state are often frozen, and the frozen storage can not be thawed and stored again in the supercooled state. There is a problem that the stability to maintain is poor.

Korean Patent No. 10-850062 has a space for storing food and a storage compartment for cooling the space, and includes a cold air circulation space for indirectly cooling the food storage space, and an insulating layer for insulating the space between the cold air flow space and the space for supercooled food. The refrigerator which can accommodate this is disclosed. However, there is no configuration that can raise the temperature when the temperature in the refrigerator falls below the set temperature, there is the same problem that the stability to maintain a freezing state likewise falls.

A refrigerator having a subcooling chamber having a control device for controlling a freezer compartment to maintain a supercooling state in which food stored in the refrigerator is not frozen at a temperature below a freezing point is disclosed. However, the temperature in the subcooling chamber is controlled by controlling the temperature of the freezing chamber or the replacement chamber in which the subcooling chamber is installed, and the temperature change of the temperature in the subcooling chamber is suppressed by closing the subcooling chamber to the freezing chamber or the replacement chamber. However, storing the food in the subcooled state by slowing the temperature fluctuation in the subcooling chamber by indirect cooling has a disadvantage in that it takes a long time until the food reaches the subcooled state. In addition, there is still a problem such that there is no configuration that can raise the temperature when the temperature in the refrigerator falls below the set temperature, likewise, the stability of maintaining a freezing state is inferior.

도 3은 본 발명에 따른 무동결 장치 및 냉각 장치에 적용되는 과냉각 과정을 나타내는 도면이다. 도 3에 도시된 바와 같이, 냉각 공간(S) 내에 액체(L)를 수용하는 용기(C)가 냉각된다. 3 is a diagram illustrating a supercooling process applied to a non-freezing device and a cooling device according to the present invention. As shown in FIG. 3, the container C containing the liquid L in the cooling space S is cooled.
냉각 공간(S)의 냉각 온도가 예를 들면, 상온에서부터 0도(물의 상전이 온도) 또는 액체(L)의 상전이 온도 이하로 냉각된다고 가정한다. 이러한 냉각이 진행될 때, 예를 들면, 물의 경우 -1 ~-5℃ 정도에서 얼음 결정이 최대로 생성되는 물의 최대 빙결정 생성대의 온도(약 -1~ -5℃) 이하에서 또는 액체(L)의 최대 빙결정 생성대 이하에서의 냉각 온도에서도 물 또는 액체(L)의 과냉각 상태를 유지시키려 한다. It is assumed that the cooling temperature of the cooling space S is cooled, for example, from room temperature to 0 degrees (phase transition temperature of water) or below the phase transition temperature of the liquid L. When such cooling proceeds, for example, at water below the maximum ice crystal formation zone (about -1 to -5 ° C) of the water where liquid crystals are produced at a maximum of about -1 to -5 ° C, or liquid (L). It is intended to maintain the supercooled state of water or liquid (L) even at a cooling temperature below the maximum ice crystal generation zone of.
이러한 냉각 중에 액체(L)로부터 증발이 이루어져서, 수증기가 용기(C) 내의 기체(또는 공간)(Lg) 내로 유입된다. 용기(C)가 뚜껑(Ck)에 의해 폐쇄된 경우, 증발된 수증기로 인하여, 기체(Cg)는 과포화 상태가 될 수 있다. 다만, 본 명세서에서 용기(C)는 뚜껑(Ck)을 선택적으로 포함할 수 있으며, 포함된 경우 냉각 공간의 냉기가 직접적으로 유입되거나, 액체(L)의 표면 또는 표면 상의 기체(Lg)의 온도가 냉기에 의해 냉각되는 것을 어느 정도 방지할 수도 있다. Evaporation takes place from the liquid L during this cooling, so that water vapor flows into the gas (or space) Lg in the vessel C. When the container C is closed by the lid Ck, the gas Cg may be in a supersaturated state due to the vaporized water vapor. However, in the present specification, the container (C) may optionally include a lid (Ck), if included, the cold air of the cooling space directly flows in, or the surface of the liquid (L) or the temperature of the gas (Lg) on the surface The cooling by the cold air can be prevented to some extent.
냉각 온도가 액체(L)의 최대 빙결정 생성대의 온도에 도달하거나 통과하면서 기체(Lg) 내의 수증기 또는 용기의 내측벽의 물방울이 결빙될 수 있다. 또는, 액체(L)의 표면(Ls)과, 용기(C)의 내측벽(냉각 공간(S)의 냉각 온도에 거의 일치함)이 접하는 부분에서 응축이 일어나고 이러한 응축된 액체(L)가 얼음 결정인 빙결핵으로 형성될 수 있다. Water droplets in the inner wall of the vessel or water vapor in the gas Lg may freeze as the cooling temperature reaches or passes the temperature of the maximum ice crystal generation zone of the liquid L. Alternatively, condensation takes place at a portion where the surface Ls of the liquid L and the inner wall of the container C (which substantially coincide with the cooling temperature of the cooling space S) are formed and the condensed liquid L is iced. It can be formed into crystalline tuberculosis.
예를 들면, 기체(Lg) 내의 빙결핵이 하강하여 액체(L)의 표면(Ls)을 통하여 액체(L)에 침투하게 되면, 액체(L)의 과냉각 상태가 해제되어, 액체(L)에 결빙 현상이 야기되어, 액체(L)의 과냉각이 해제된다. For example, when the frozen tuberculosis in the gas Lg descends and penetrates into the liquid L through the surface Ls of the liquid L, the supercooled state of the liquid L is released to the liquid L. A freezing phenomenon is caused and the supercooling of the liquid L is released.
또는, 빙결핵이 액체(L)의 표면(Ls)과 접하게 됨으로써, 액체(L)의 과냉각 상태가 해제되어, 액체(L)에 결빙 현상이 야기될 수 있다. Alternatively, when the frozen tuberculosis comes into contact with the surface Ls of the liquid L, the supercooled state of the liquid L may be released, thereby causing a freezing phenomenon in the liquid L. FIG.
이에 따라, 본 발명인 과냉각 장치는 냉각 공간(S)에 수납된 용기(C) 및 액체(L)에 에너지(예를 들면, 열에너지)를 인가 또는 공급하여, 기체(Lg) 및 액체(L)의 온도를 제어하여, 액체(L)가 액체의 상전이 온도 이하에서도 무동결 상태 즉, 과냉각 상태를 유지하도록 한다. 여기서, 기체(Lg)는 액체(L)에 접하면서 액체(L)의 상층부에 위치하는 것으로, 본 명세서에서는 액체 상층부(또는 수납물 상층부)로 정의되며, 이러한 액체 상층부는 기체(Lg) 이외에도, 액체(L)에 부유할 수 있는 기름층 또는 플라스틱 또는 기타 수지를 포함하는 물체가 될 수 있다. 아울러, 본 실시예에서 편의상, 액체(L)로 기재되어 있으나, 액체(L)뿐만 아니라, 육류 및 어류, 야채, 과일 등과 같은 일반 수납물에도 적용될 수 있다. Accordingly, the supercooling device of the present invention applies or supplies energy (for example, thermal energy) to the container C and the liquid L stored in the cooling space S, so that the gas Lg and the liquid L By controlling the temperature, the liquid L is maintained in the freezing state, that is, the supercooling state, even below the phase transition temperature of the liquid. Here, the gas (Lg) is located in the upper layer portion of the liquid (L) in contact with the liquid (L), and is defined herein as the liquid upper layer (or the upper portion of the package), in addition to the gas (Lg), It may be an object containing an oil layer or plastic or other resin that may float in the liquid (L). In addition, in the present embodiment, it is described as a liquid (L) for convenience, but may be applied to not only the liquid (L) but also general objects such as meat, fish, vegetables, fruits, and the like.
이러한 온도 제어에 의한 과냉각 상태의 유지는 도 4 및 5에서 상세하게 설명된다. The maintenance of the supercooled state by this temperature control is described in detail in FIGS. 4 and 5.
도 4는 본 발명에 따른 무동결 장치에 적용되는 빙결핵 생성을 방지하는 과정을 나타내는 도면이다. 4 is a view showing a process for preventing the formation of ice tuberculosis applied to the non-freezing apparatus according to the present invention.
도 4는 기체(Lg) 내의 수증기(W1)의 결빙을 방지하여, 즉, 지속적으로 수증기(W1) 상태가 유지되도록, 적어도 기체(Lg) 또는 액체(L)의 표면(Ls) 상에 에너지를 인가하여, 기체(Lg) 또는 액체(L)의 표면(Ls)상의 온도를 액체(L)의 최대 빙결정 생성대의 온도보다 높도록, 더욱 바람직하게는, 액체(L)의 상전이 온도 이상으로 한다. 또한, 액체(L)의 표면(Ls)이 용기(C)의 내측벽에 접촉하더라도 결빙이 되지 않도록, 액체(L)의 표면(Ls)의 온도를 액체(L)의 최대 빙결정 생성대의 온도보다 높도록, 더욱 바람직하게는, 액체(L)의 상전이 온도 이상으로 한다. 4 shows energy at least on the surface Ls of the gas Lg or the liquid L so as to prevent the freezing of the water vapor W1 in the gas Lg, ie to maintain the water vapor W1 state continuously. The temperature of the gas Lg or the surface Ls of the liquid L is applied to be higher than the temperature of the maximum ice crystal generation zone of the liquid L. More preferably, the phase transition temperature of the liquid L is equal to or higher than that of the liquid L. . In addition, the temperature of the surface Ls of the liquid L is set to the temperature of the maximum ice crystal generation zone of the liquid L so that the surface Ls of the liquid L does not freeze even if it contacts the inner wall of the container C. More preferably, the phase transition temperature of the liquid L is equal to or higher than that.
이에 따라, 용기(C) 내의 액체(L)가 상전이 온도 이하에서, 또는 액체(L)의 최대 빙결정 생성대 온도 이하에서도 과냉각 상태를 유지하게 된다. As a result, the liquid L in the container C is maintained in the supercooled state at or below the phase transition temperature or below the maximum ice crystal generation temperature of the liquid L.
또한, 저장고(S) 내의 냉각 온도가 예를 들면, -20℃와 같이, 상당히 저온일 경우, 용기(C)의 상부에만 에너지를 인가하는 것만으로는, 수납물인 액체(L)가 과냉각 상태를 유지할 수 없을 수도 있기에, 용기(C)의 하부에도 어느 정도의 에너지를 공급할 필요가 있다. 용기(C)의 상부에 인가되는 에너지가 용기(C)의 하부에 인가되는 에너지에 비하여 상대적으로 크게 하여, 용기(C)의 상부 온도를 상전이 온도 또는 최대빙결정 생성대의 온도보다 높게 유지할 수 있다. 또한, 이러한 용기(C)의 하부에 인가되는 에너지와, 용기(C)의 상부에 인가되는 에너지에 의해 액체(L)의 과냉각 상태에서의 온도를 조절할 수 있게 된다. In addition, when the cooling temperature in the storage S is very low, for example, -20 ° C, the liquid L, which is an object, may be subjected to a supercooling state simply by applying energy only to the upper portion of the container C. Since it may not be able to hold | maintain, it is necessary to supply some energy also to the lower part of the container C. The energy applied to the upper portion of the vessel C is relatively larger than the energy applied to the lower portion of the vessel C, so that the upper temperature of the vessel C can be maintained higher than the phase transition temperature or the temperature of the maximum ice crystal generation zone. . In addition, it is possible to control the temperature in the supercooled state of the liquid (L) by the energy applied to the lower portion of the container (C) and the energy applied to the upper portion of the container (C).
상술된 도 3 및 도 4의 경우, 액체(L)의 경우를 예시적으로 설명하였으나, 액체를 포함하는 수납물의 경우에도 수납물 내의 액체를 지속적으로 과냉각시킴으로써 수납물의 신선한 장기 보관이 가능하게 되므로, 위의 과정을 적용하여 수납물이 상전이 온도 이하에서 과냉각 상태로 유지될 수 있다. 여기에서의 수납물은 액체 뿐만 아니라, 육류, 야채, 과일, 기타 식품 등을 포함할 수 있다. 3 and 4 described above, the case of the liquid (L) has been exemplarily described, but even in the case of the package containing the liquid, the fresh long-term storage of the package is possible by continuously supercooling the liquid in the package, By applying the above process, the enclosure can be maintained in a supercooled state below the phase transition temperature. Receptacles herein can include meat, vegetables, fruits, other foods, and the like, as well as liquids.

도 9는 본 발명의 제5 실시예에 따른 냉각 장치를 도시한 도면이다. 본 발명의 제5 실시예에서는 냉동실 또는 냉장실의 도어(1100, 1200)에 무동결 장치(2000)가 홈바형으로 설치되었다. 무동결 장치(2000)는 냉동실 또는 냉장실의 도어(1100, 1200)와 동일한 외장을 가지며 외부에서 볼 때 냉동실 또는 냉장실의 도어(1100, 1200)와 평평한 면을 이루는 무동결 장치(2000)의 도어(200)를 구비한다. 즉, 무동결 장치(2000)의 내부 공간(100U, 100L)이 냉동실 또는 냉장실 도어(1100, 1200)에 설치된 홈바의 저장 공간이 되며, 무동결 장치(2000)의 도어(200)가 홈바의 도어 역할을 한다고 볼 수 있다. 무동결 장치(2000)의 도어(200)가 홈바의 도어 역할을 해주어야 하므로, 도어(200)의 내부에는 단열재(202)가 충진된다. 한편 무동결 장치(2000)가 홈바형으로 설치되는 냉각 장치(1000)의 도어는 냉동실 도어(1100)일 수도 있고, 냉장실 도어(1200)일 수도 있다. 냉장실 도어(1200)에 무동결 장치(2000)가 설치되는 경우, 냉동실 도어(1100)로부터 냉기를 도입하는 별도의 유로가 형성되어야 하며, 유로를 형성하는 유로 안내 구조는 제4 실시예에 도시된 개구부(1110: 도 8 참조)와 가이드 덕트(2300: 도 8 참조)와 유사한 구조를 이용할 수 있다. 한편 개구부 상, 가이드 덕트 내부 또는 무동결 장치(2000) 등의 무동결 장치(2000)로 냉기가 도입되는 유로 상에 냉기의 도입을 조절하는 댐퍼(미도시)가 설치될 수 있다. 한편, 무동결 장치(2000)가 홈바의 형태로 냉각 장치(1000)에 설치되면 무동결 장치(2000)를 이용할 때, 냉동실 도어(1100) 또는 냉장실 도어(1200)를 개방할 필요 없이 무동결 장치(2000)의 도어(200)만을 개방하여 이용하면 되므로 외기가 냉동실(1300) 또는 냉장실(1400)로 유입되지 않는다. 따라서 냉동실(1300) 또는 냉장실(1400)의 온도가 상승되지 않으므로 식품의 보관 안정성이 높아질 뿐 아니라 에너지 효율도 높일 수 있다. 또한 무동결 장치(2000)의 도어(200)를 개방하여도 무동결 장치(2000)의 도어(200)에 해당하는 면적만이 외기에 노출되고, 무동결 장치(2000)의 후방 공간은 그대로 냉각 장치(1000)의 냉각 공간 내에 위치하여 무동결 장치(2000) 내부의 온도가 급격하게 향상되지 않는다. 따라서 무동결 장치(2000)의 도어(200)가 개방되는 중에도 무동결 장치(2000) 내에 저장되는 식품을 안정적으로 무동결 상태로 보관할 수 있다. 9 is a view showing a cooling device according to a fifth embodiment of the present invention. In the fifth embodiment of the present invention, the non-freezing device 2000 is installed in a groove bar shape in the doors 1100 and 1200 of the freezing compartment or the refrigerating compartment. The non-freezing apparatus 2000 has the same exterior as the doors 1100 and 1200 of the freezing compartment or the refrigerating compartment, and the door of the non-freezing apparatus 2000 which forms a flat surface with the doors 1100 and 1200 of the freezing compartment or the refrigerating compartment. 200). That is, the interior spaces 100U and 100L of the non-freezing apparatus 2000 become storage spaces of the home bars installed in the freezer compartment or the refrigerator compartment doors 1100 and 1200, and the door 200 of the non-freezing apparatus 2000 is the door of the home bar. It can be said that it plays a role. Since the door 200 of the non-freezing device 2000 should serve as the door of the home bar, the heat insulator 202 is filled in the door 200. Meanwhile, the door of the cooling device 1000 in which the non-freezing device 2000 is installed in the groove bar shape may be the freezing compartment door 1100 or the refrigerating compartment door 1200. When the non-freezing device 2000 is installed in the refrigerating compartment door 1200, a separate flow path for introducing cold air from the freezing compartment door 1100 should be formed, and the flow path guide structure for forming the flow path is illustrated in the fourth embodiment. A structure similar to the opening 1110 (see FIG. 8) and the guide duct 2300 (see FIG. 8) may be used. On the other hand, a damper (not shown) for controlling the introduction of cold air may be installed on the opening, inside the guide duct, or on a flow path through which cold air is introduced into the non-freezing device 2000 such as the non-freezing device 2000. Meanwhile, when the non-freezing device 2000 is installed in the cooling device 1000 in the form of a home bar, when the non-freezing device 2000 is used, the freezing device 1100 or the freezer door 1200 does not need to be opened without the need for opening the freezing device 2000. Since only the door 200 of 2000 may be opened and used, outside air does not flow into the freezing chamber 1300 or the refrigerating chamber 1400. Therefore, since the temperature of the freezing chamber 1300 or the refrigerating chamber 1400 is not increased, not only the storage stability of food is increased but also the energy efficiency may be increased. In addition, even when the door 200 of the non-freezing device 2000 is opened, only the area corresponding to the door 200 of the non-freezing device 2000 is exposed to the outside air, and the rear space of the non-freezing device 2000 is cooled as it is. Located in the cooling space of the device 1000, the temperature inside the freezing device 2000 does not sharply increase. Therefore, even when the door 200 of the non-freezing device 2000 is opened, food stored in the non-freezing device 2000 can be stably stored in the non-freezing state.
도 10 및 도 11은 본 발명의 제6 실시예에 따른 냉각 장치를 도시한 도면이다. 본 발명의 제6 실시예에 따른 냉각 장치는 무동결 장치(2000)가 냉동실 또는 냉장실 도어(1100, 1200)의 홈바 내에 별도로 설치된 것이다. 냉동실 또는 냉장실 도어(1100, 1200)는 일반적인 홈바와 같이 수납 공간과, 수납 공간을 냉각 장치(1000)의 외부에서 개폐하는 홈바 도어(1020)를 포함한다. 이러한 수납 공간 내부에 무동결 장치(2000)가 설치되며, 무동결 장치(2000)의 형태는 도 12 내지 도 19에 도시된 무동결 장치(2000)와 동일하다. 즉, 무동결 장치(2000) 내부에 저장되고 있는 용기를 꺼내기 위해서는 냉각 장치(1000)의 홈바 도어(1020)를 개방한 다음, 무동결 장치(2000)의 도어(200)를 개방하여야 한다. 이 경우 사용자가 홈바 도어(1020)와 무동결 장치(2000)의 도어(200)를 두 번 개방하여야 하다는 사용상의 불편은 있으나, 냉기의 손실이 가장 적고, 무동결 장치(2000) 내부 공간의 온도 변화가 극히 적어 안정적으로 식품에 급격한 온도 변화를 일으키지 않고 안정적으로 무동결 상태로 보관할 수 있다는 장점이 있다. 일반적인 홈바 내에 무동결 장치(2000)가 설치되는 경우에도, 홈바 자체가 냉장실 도어(1200)에 설치될 수도 있고, 냉동실 도어(1100)에 설치될 수도 있다. 또한 앞서 설명한 바와 같이 무동결 장치가 냉장실 도어(1200)에 형성된 홈바 내에 설치되는 경우, 냉동실(1300)의 냉기를 냉장실에 형성된 홈바 내로 도입하는 별도의 유로가 필요하다. 또한 무동결 장치(2000)로 도입되는 냉기를 단속하는 댐퍼가 냉기를 도입하는 유로 상에 설치되어 무동결 장치(2000) 내로 유입되는 냉기를 조절한다. 10 and 11 illustrate a cooling apparatus according to a sixth embodiment of the present invention. In the cooling apparatus according to the sixth embodiment of the present invention, the non-freezing apparatus 2000 is separately installed in the home bars of the freezer compartment or the refrigerator compartment doors 1100 and 1200.

The non-freezing device 2000 is installed in the storage space, and the shape of the non-freezing device 2000 is the same as that of the non-freezing device 2000 illustrated in FIGS. 12 to 19. That is, in order to take out the container stored in the non-freezing apparatus 2000, the home bar door 1020 of the cooling apparatus 1000 should be opened, and then the door 200 of the non-freezing apparatus 2000 should be opened. In this case, the user has to open the home bar door 1020 and the door 200 of the non-freezing device 2000 twice, but the loss of cold air is the least, and the temperature of the internal space of the non-freezing device 2000 is minimal. It has the advantage that it can be stored stably without freezing without causing a sudden change in temperature due to the extremely small change. Even when the non-freezing device 2000 is installed in a general home bar, the home bar itself may be installed in the refrigerating compartment door 1200 or may be installed in the freezer compartment door 1100. In addition, when the non-freezing apparatus is installed in the home bar formed in the refrigerating compartment door 1200 as described above, a separate flow path for introducing the cold air of the freezing compartment 1300 into the home bar formed in the refrigerating compartment is required. In addition, the damper for regulating the cold air introduced into the non-freezing device 2000 is installed on the flow path for introducing the cold air to control the cold air introduced into the non-freezing device 2000.

PCB와 각 전장품들을 연결하는 전선은 PCB 설치부(186)를 후방 외부 케이싱(120)의 개구부(124)를 통해 인출할 수 있도록 충분히 긴 여분의 길이를 가지고 PCB에 연결된다. 따라서 PCB를 수리하거나 교체할 때, 전방 외부 케이싱(110)과 후방 외부 케이싱(120)을 분리할 필요가 없어서, 유지, 보수가 편리하다는 이점이 있다. 또한 하부 케이싱(140)과 상부 케이싱(150)은 각각, 하부 케이싱(140)의 상부와 상부 케이싱(150)의 하부에 PCB와 전장품들을 연결하는 전선을 끼울 수 있는 홈(146, 156)을 구비한다. 하부 케이싱(140)의 상부와 상부 케이싱(150)의 하부는 서로 겹쳐져서 고정될 수 있도록 하며, 이 하부 케이싱(140)의 상부와 상부 케이싱(150)의 하부 사이에 상기에서 설명한 분리막(142)이나 고정 플레이트(144)가 위치된다. 또한 PCB 설치부(186)를 후방 외부 케이싱(120) 내의 상부 공간의 단열재(122)에 삽입하고 나면, PCB 커버(124c)를 이용하여 개구부(124)를 폐쇄한다. 작동 중에 개구부(124)를 통하여 냉각 공간의 냉기가 침입할 경우, 냉각 공간은 물론 하부 공간(100L)보다 높은 온도로 유지되어야 하는 상부 공간(100U)의 온도를 저하시킬 우려가 있으므로 상부 히터(미도시)의 발열량을 증가시켜야 하는 단점이 있다. 따라서 개구부(124)를 PCB 커버(124c)를 통해 폐쇄하여 에너지 효율을 높이고, 좀 더 안정적으로 액체를 과냉각 상태로 만들 수 있다. Meanwhile, the rear space R is defined by the rear outer casing 120, the lower casing 130, and the upper casing 150, and the rear space R has a flow fan 170, a damper 190, and a lower heater. (Not shown) is installed, and in particular, the PCB installation unit 186 is detachably installed at the upper portion of the rear space R. Lower heater (not shown), upper heater (not shown), lower sensor (not shown), upper sensor (not shown), flow fan 170, damper 190, switch 182 and display 184 are wires Is connected to the PCB. The PCB is fixed in the PCB mounting portion 186, and then the PCB mounting portion 186 is fitted into a groove formed in the insulation 122 of the upper space through the opening 124 formed in the rear outer casing 120. The wires connecting the PCB and each electrical component are connected to the PCB with an extra length long enough to lead the PCB installation portion 186 through the opening 124 of the rear outer casing 120. Therefore, when repairing or replacing the PCB, there is no need to separate the front outer casing 110 and the rear outer casing 120, there is an advantage that the maintenance, repair is convenient. In addition, the lower casing 140 and the upper casing 150 are provided with grooves 146 and 156 for inserting electric wires connecting the PCB and the electrical equipment to the upper part of the lower casing 140 and the lower part of the upper casing 150, respectively. do. The upper part of the lower casing 140 and the lower part of the upper casing 150 may overlap and be fixed to each other, and the separator 142 described above may be disposed between the upper part of the lower casing 140 and the lower part of the upper casing 150. Or fixed plate 144 is located. In addition, after the PCB installation unit 186 is inserted into the heat insulating material 122 of the upper space in the rear outer casing 120, the opening 124 is closed using the PCB cover 124c. If cold air in the cooling space penetrates through the opening 124 during operation, there is a risk of lowering the temperature of the upper space 100U, which must be maintained at a temperature higher than the lower space 100L, as well as the upper space (not shown). There is a disadvantage to increase the amount of heat generated. Therefore, the opening 124 may be closed through the PCB cover 124c to increase energy efficiency, and to make the liquid subcooled more stably.
도 14 내지 도 16은 본 발명의 일 실시예에 따른 무동결 장치가 구비하는 댐퍼를 도시한 도면이다. 댐퍼(170)는 상기에서 설명한 바와 같이 후방 공간(100R: 도 12에 도시) 설치되며, 무동결 장치(2000)가 설치된 냉각 공간으로부터 후방 공간(100R: 도 12에 도시)으로 냉기가 유입되는 것을 조절한다. 댐퍼(170)는 후방 외부 케이싱(120)에 설치되는 프레임(172)과 프레임(172)에 대해 회동하며 프레임(172) 내의 개구부를 개방하거나 폐쇄한다. 댐퍼(170)는 전선에 의해 PCB에 연결되어 있으며, PCB는 센서(미도시)가 측정한 하부 공간(100L)의 온도 정보에 따라 댐퍼(170)의 개방/폐쇄를 조절한다. 댐퍼가 닫혀있을 때는 냉각 장치(1000) 내의 냉기가 무동결 장치(2000)를 간접적으로 냉각하는 제1 냉각 방식으로 무동결 장치(2000)가 냉각된다. 한편 댐퍼가 개방된 때는 냉각 장치(1000) 내의 냉기가 무동결 장치(2000) 주변을 순환하며 간접적으로 냉각하는 동시에 냉기가 댐퍼를 통해 무동결 장치(2000) 내로 유입되어 냉기가 직접 무동결 장치 내부를 순환하는 제2 냉각 방식이 함께 수행된다. 즉, 무동결 장치(2000)는 냉각 장치(2000) 내에서 제1 냉각 방식으로 냉각되면서, 댐퍼(170)의 개폐 여부에 따라 선택적으로 제2 냉각 방식이 제1 냉각 방식과 더불어 수행된다. 즉 댐퍼(170)의 폐쇄시에는 무동결 장치(2000)가 제1 냉각 방식으로 냉각되고, 댐퍼(170)가 개방되면 제1 냉각 방식 및 제2 냉각 방식에 의해 냉각된다. 14 to 16 illustrate dampers provided in the non-freezing apparatus according to the embodiment of the present invention. As described above, the damper 170 is installed in the rear space 100R (shown in FIG. 12), and the cold air flows into the rear space 100R (shown in FIG. 12) from the cooling space in which the freezing device 2000 is installed. Adjust The damper 170 rotates with respect to the frame 172 and the frame 172 installed in the rear outer casing 120 and opens or closes the opening in the frame 172. Damper 170 is connected to the PCB by a wire, the PCB controls the opening / closing of the damper 170 according to the temperature information of the lower space (100L) measured by the sensor (not shown). When the damper is closed, the non-freezing device 2000 is cooled by a first cooling method in which cold air in the cooling device 1000 indirectly cools the non-freezing device 2000. On the other hand, when the damper is opened, the cold air in the cooling device 1000 circulates around the non-freezing device 2000 and indirectly cools, while the cold air flows into the non-freezing device 2000 through the damper so that the cold air is directly inside the non-freezing device. A second cooling scheme to circulate is performed together. That is, while the non-freezing device 2000 is cooled in the cooling device 2000 in the first cooling method, the second cooling method is selectively performed along with the first cooling method according to whether the damper 170 is opened or closed. That is, when the damper 170 is closed, the non-freezing device 2000 is cooled by the first cooling method, and when the damper 170 is opened, it is cooled by the first cooling method and the second cooling method.
도 17은 본 발명의 일 실시예에 따른 무동결 장치의 후방 공간을 도시한 도면이고, 도 18은 본 발명의 일 실시예에 따른 무동결 장치의 사시도이다. 후방 공간(100R)에는 상기에서 설명한 바와 같이 하부에 댐퍼(190)가 설치되어 냉기의 유입을 조절한다. 또한 하부 케이스(130)의 배면에 설치된 유동 팬(170)은 강제 유동을 발생시켜, 후방 공간(100R)으로 유입된 공기가 하부 공간(100L)으로 유입되며, 하부 공간(100L)의 공기가 다시 후방 공간(100R)으로 토출될 수 있도록 한다. 하부 케이스(130)의 유동 팬(170)이 설치되는 위치에는 유동 팬(170)이 발생시키는 유동이 흐를 수 있도록 토출 그릴(172)이 형성되어, 후방 공간(100R)으로부터 하부 공간(100U)으로 흐르는 유로를 형성한다. 또한 하부 케이스(130)의 배면에는 하부 공간(100U)으로부터 후방 공간(100R)으로 유동을 토출하는 제1 토출홀(310a, 310b, 310c, 310d)이 형성된다. 제1 토출홀(310)은 양 측단에 각각 형성되며, 상, 하 두 개씩 총 4개의 제1 토출홀(310a, 310b, 310c, 310d)이 형성된다. 유동 팬(170)에 의해 발생한 유동이 토출 그릴(172)을 통해 하부 공간(100L)으로 유입된 다음, 양 측단에 위치하는 제1 토출홀(310a, 310b, 310c, 310d)로 재토출되도록 하여 자연스럽게 하부 공간(100L) 내에 냉각 유로가 형성되도록 한다. 한편 하부 공간(100L)의 하부에는 제1 토출홀(310a, 310b, 310c, 310d)로부터 토출 된 유동을 냉각 공간으로 토출되도록 하는 제2 토출홀(320)가 형성된다. 이때, 제1 토출홀(310a, 310b, 310c, 310d)을 통해 토출된 유동이 유동팬(170)이 위치하는 중앙부로 다시 흘러가서 다시 하부 공간(100U)으로 유입되는 것을 방지하기 위해 유동팬(170)과 제1 토출홀(310a, 310b, 310c, 310d) 사이에는 격벽(330a,330b)이 설치된다. 17 is a view showing the rear space of the non-freezing apparatus according to an embodiment of the present invention, Figure 18 is a perspective view of the non-freezing apparatus according to an embodiment of the present invention. As described above, the rear space 100R is provided with a damper 190 to adjust the inflow of cold air. In addition, the flow fan 170 installed on the rear surface of the lower case 130 generates a forced flow, so that the air introduced into the rear space 100R flows into the lower space 100L, and the air in the lower space 100L again. It can be discharged to the rear space 100R. At the position where the flow fan 170 of the lower case 130 is installed, a discharge grill 172 is formed so that the flow generated by the flow fan 170 flows, from the rear space 100R to the lower space 100U. Form a flowing flow path. Further, first discharge holes 310a, 310b, 310c, and 310d for discharging flow from the lower space 100U to the rear space 100R are formed on the rear surface of the lower case 130. The first discharge holes 310 are formed at both side ends, and a total of four first discharge holes 310a, 310b, 310c, and 310d are formed, two up and down. The flow generated by the flow fan 170 flows into the lower space 100L through the discharge grill 172, and then is re-discharged to the first discharge holes 310a, 310b, 310c, and 310d located at both ends. The cooling passage is naturally formed in the lower space 100L. Meanwhile, a second discharge hole 320 is formed below the lower space 100L to discharge the flow discharged from the first discharge holes 310a, 310b, 310c, and 310d into the cooling space. At this time, the flow discharged through the first discharge hole (310a, 310b, 310c, 310d) flows back to the center portion where the flow fan 170 is located to flow back into the lower space (100U) to prevent the flow fan ( Partition walls 330a and 330b are installed between the 170 and the first discharge holes 310a, 310b, 310c and 310d.
또한 제1 토출홀(310a, 310b, 310c, 310d)을 통해 하부 공간(100L)으로 유입되어 용기에 저장된 액체를 냉각한 유동의 일부는 하부 공간(100L)의 하부에 위치하는 제3 토출홀(340)을 통해 냉각 공간으로 직접 토출된다. 제3 토출홀(340)은 대칭적인 유로를 형성하기 위해 좌, 우에 각각 동일한 개수로 형성되는 것이 바람직하다. In addition, a part of the flow that cools the liquid stored in the container through the first discharge holes 310a, 310b, 310c, and 310d and cools the liquid stored in the container is located in the lower portion of the lower space 100L ( It is discharged directly to the cooling space through the 340. The third discharge holes 340 are preferably formed in the same number on the left and right sides to form a symmetric flow path.
따라서 댐퍼(190)를 개방하고, 유동 팬(170)을 가동하는 경우, 댐퍼(190)를 통해 냉각 공간으로부터 냉기가 후방 공간(100R)으로 유입된 다음, 후방 공간(100R)으로부터 토출 그릴(172)을 통해 하부 공간(100L)으로 유입되어 무동결 장치 내에 저장된 액체를 저장하는 용기의 하부를 냉각한다. 용기에 저장된 액체와 열교환하며 액체를 냉각한 유동의 일부는 하부 공간(100L)의 하부 양측에 위치한 제3 토출홀(340)을 통해 냉각 공간으로 직접 토출되고, 나머지는 양 측단의 제1 토출홀(310a, 310b, 310c, 310d)을 통해 후방 공간(100R)으로 토출된 다음, 제2 토출홀(320a, 320b)를 통해 외부(냉각 공간)로 토출된다. Therefore, when the damper 190 is opened and the flow fan 170 is operated, cold air flows into the rear space 100R from the cooling space through the damper 190, and then the discharge grill 172 from the rear space 100R. Cooling the lower part of the container that flows into the lower space (100L) to store the liquid stored in the non-freezing apparatus. A part of the flow that cools the liquid while exchanging heat with the liquid stored in the container is directly discharged to the cooling space through the third discharge holes 340 located on both sides of the lower part of the lower space 100L, and the others are the first discharge holes at both ends. It is discharged to the rear space 100R through 310a, 310b, 310c, 310d, and then to the outside (cooling space) through the second discharge holes 320a and 320b.
한편 하부 케이스(130)에서 격벽(330a, 330b)에 대해 내측에 위치하는 제4 토출홀(350a, 350b)을 더 포함한다. 즉, 제4 토출홀(350a, 350b)은 제1 토출홀(310a, 310b, 310c, 310d) 및 제2 토출홀(320a, 320b)와 격벽(330a, 330b)을 사이에 두고 형성된다. 댐퍼(190)가 폐쇄된 상태에서 유동 팬(170)이 작동될 경우, 후방 공간(100R)으로부터 토출 그릴(172)를 통해 하부 공간(100L)으로 토출된 유동은 하부 공간(100L)을 순환하다가 다시 제4 토출홀(350a, 350b)을 통해 후방 공간(100R)으로 토출된다. 즉, 하부 공간(100L)의 온도가 액체를 과냉각 상태로 저장하기 적절한 온도에 도달했다고 판단되면, 댐퍼(190)를 폐쇄한 상태에서는 토출 그릴(172)과 제4 토출홀(350a, 350a)을 통해 하부 공간(100L)과 후방 공간(100R) 사이에서만 순환하는 유동을 형성하고, 외부의 냉각 공간으로부터 냉기를 더 이상 유입하지 않는다. The lower case 130 further includes fourth discharge holes 350a and 350b positioned inside the partition walls 330a and 330b. That is, the fourth discharge holes 350a and 350b are formed with the first discharge holes 310a, 310b, 310c and 310d and the second discharge holes 320a and 320b and the partition walls 330a and 330b interposed therebetween. When the flow fan 170 is operated while the damper 190 is closed, the flow discharged from the rear space 100R through the discharge grill 172 to the lower space 100L circulates in the lower space 100L. The liquid is discharged to the rear space 100R through the fourth discharge holes 350a and 350b again. That is, when it is determined that the temperature of the lower space 100L reaches a temperature suitable for storing the liquid in the supercooled state, the discharge grill 172 and the fourth discharge holes 350a and 350a are opened in the state where the damper 190 is closed. Through this, a circulating flow is formed only between the lower space 100L and the rear space 100R, and cold air is no longer introduced from the external cooling space.
한편 도 18을 참조하면, 도어(200)와 전방 외부 케이스(110)가 맞닿는 부분에는 물받이(116)가 형성된다. 물받이(126)는 용기에 맺힌 이슬이나 습기가 도어(200)나 전방 외부 케이스(110)에 동결되어 도어(200)와 외부 케이스(110)가 제대로 밀착되지 않고 틈새가 발생하여, 틈새로 냉기가 침입하여 하부 공간(100L)의 온도를 떨어트리는 것을 방지한다. 즉, 도어(200)나 외부 케이스(110)에 맺힌 이슬이 하부로 내려와 물받이(116) 내로 모이도록 함으로써, 도어(200)와 맞닿는 외부 케이스(110)의 하면에 성에가 발생하거나 수분이 동결되는 것을 방지한다. Meanwhile, referring to FIG. 18, a drip tray 116 is formed at a portion where the door 200 and the front outer case 110 contact each other. The drip tray 126 freezes dew or moisture formed in the container on the door 200 or the front outer case 110 so that a gap occurs without the door 200 and the outer case 110 contacting each other properly. Intrusion is prevented from dropping the temperature of the lower space 100L. That is, dew formed on the door 200 or the outer case 110 is lowered and collected into the drip tray 116, whereby frost is generated or water is frozen on the lower surface of the outer case 110 in contact with the door 200. To prevent them.
도 19는 본 발명의 일 실시예에 따른 무동결 장치의 후방을 도시한 도면이다. 후방 외부 케이스(120)의 배면 중앙측에는 후방 공간(100R)으로부터 냉각 공간으로 유동을 배출하는 제5 토출홀(360a, 360b, 360c)가 형성되어 있다. 댐퍼(190)를 통해 냉각 공간으로부터 후방 공간(100R)으로 유입된 냉기 중 일부는 토출 그릴(172)을 통해 하부 공간(100L)으로 유입되는 대신 제5 토출홀(360a, 360b, 360c)을 통해 냉각 공간으로 다시 빠져나간다. 19 is a view showing the rear of the non-freezing apparatus according to an embodiment of the present invention. Fifth discharge holes 360a, 360b, and 360c for discharging the flow from the rear space 100R to the cooling space are formed at the rear center side of the rear outer case 120. Some of the cold air introduced into the rear space 100R from the cooling space through the damper 190 is not introduced into the lower space 100L through the discharge grill 172 but through the fifth discharge holes 360a, 360b, and 360c. Exit back to the cooling space.
한편 후방 외부 케이스(120)의 배면에는 복수 개의 리브(125)가 형성된다. 리브(125)는 후방 외부 케이스(120)의 배면과 설치면과의 간격을 주기 위한 것으로, 본 발명의 실시예와 같이 무동결 장치(2000)가 냉각 장치(1000)에 설치될 때, 냉각 장치(1000)의 내면과 후방 외부 케이스(120)의 배면의 간격을 유지해주는 역할을 한다. 냉각 장치(1000)의 내면은 냉동실 도어(1100) 및 냉장실 도어(1200)의 내면을 포함하는 의미이다. 한편 후방 외부 케이스(120)의 배면 중앙측에 형성된 제5 토출홀(360a, 360b, 360c)로 토출되는 유동이 후방 케이스(120)의 하부로 안내되도록 하기 위해, 후방 외부 케이스(120)의 제5 토출홀(360a, 360b, 360c) 주위를 둘러싸는 별도의 리브(126)가 형성된다. 이 별도의 리브(126)는 제5 토출홀(360a, 360b, 360c)의 하방을 제외한 나머지 3방향을 둘러싸도록 형성되어 제5 토출홀(360a, 360b, 360c)을 통해 토출된 유동이 자연스럽게 무동결 장치(2000)의 하방으로 안내되도록 한다. Meanwhile, a plurality of ribs 125 are formed on the rear surface of the rear outer case 120. Rib 125 is to give a distance between the rear surface and the mounting surface of the rear outer case 120, when the non-freezing device 2000 is installed in the cooling device 1000, as in the embodiment of the present invention, the cooling device The inner surface of the 1000 and the rear outer case 120 serves to maintain the gap between the back. The inner surface of the cooling apparatus 1000 is meant to include the inner surfaces of the freezer compartment door 1100 and the refrigerating compartment door 1200. Meanwhile, in order for the flow discharged to the fifth discharge holes 360a, 360b, and 360c formed at the rear center side of the rear outer case 120 to be guided to the lower part of the rear case 120, the first case of the rear outer case 120 is formed. 5 A separate rib 126 is formed to surround the discharge holes 360a, 360b, and 360c. The separate ribs 126 are formed to surround the remaining three directions except for the lower portions of the fifth discharge holes 360a, 360b, and 360c, so that the flow discharged through the fifth discharge holes 360a, 360b, and 360c is naturally free. Guided below the freezing device 2000.
도 20 및 도 21은 무동결 장치가 냉각 장치에 밀착되어 설치된 경우 및 냉각 장치에 간격을 두고 설치된 경우의 열 전달을 비교한 개략도이다. 도 20에서와 같이 무동결 장치(2000)가 냉각 장치(1000)에 밀착된 경우는 냉각 장치(1000) 내측의 온도와 무동결 장치(2000)가 접촉하는 면이 서로 열교환을 하게 되므로 냉각 장치(1000)의 내측면과 무동결 장치(2000)의 접촉면이 서로 동일한 온도를 가진다. 그러나, 무동결 장치(2000)가 리브(125)에 의해 간격을 두고 설치되는 경우 냉각 장치(1000)의 내측면과 별도의 온도로 유지될 수 있다. 따라서 무동결 장치(2000)에 대한 냉각 장치 외부의 외기의 영향을 줄일 수 있다. 또한 무동결 장치(2000) 내부의 온도가 액체를 과냉각 상태로 저장할 수 있는 온도로 떨어진 이후에는 무동결 장치(2000)에 설치되는 상, 하부 히터(미도시)의 발열량을 줄일 수 있어 무동결 장치(2000)의 에너지 효율을 높일 수 있다. 무동결 장치(2000))가 냉각 장치(1000)에 밀착된 경우에는, 냉각 장치(1000)로의 열전달이 있으므로 무동결 장치(2000) 내부의 온도를 일정 온도 영역으로 유지하기 위해서 히터를 작동시키는 경우, 무동결 장치(2000) 밀착된 냉각 장치(1000) 내면의 온도를 올려주기 위해 히터가 발생하는 열이 이용된다. 따라서 냉각 장치(1000)와 간격을 두고 무동결 장치(2000)가 설치되는 것이 액체를 과냉각 상태로 빠르게 만들 수 있으며, 무동결 장치(2000)의 에너지 효율도 더 높일 수 있다.20 and 21 are schematic views comparing heat transfer when the non-freezing apparatus is installed in close contact with the cooling apparatus and when the non-freezing apparatus is installed at an interval between the cooling apparatuses. As shown in FIG. 20, when the non-freezing device 2000 is in close contact with the cooling device 1000, the temperature inside the cooling device 1000 and the surface where the non-freezing device 2000 comes into contact with each other exchange heat to each other. The inner surface of 1000 and the contact surface of the non-freezing device 2000 have the same temperature. However, when the non-freezing apparatus 2000 is installed at intervals by the ribs 125, the non-freezing apparatus 2000 may be maintained at a temperature separate from the inner surface of the cooling apparatus 1000. Therefore, the influence of the outside air outside the cooling device on the non-freezing device 2000 can be reduced. In addition, after the temperature inside the non-freezing apparatus 2000 drops to a temperature at which the liquid can be stored in a supercooled state, the amount of heat generated by the upper and lower heaters (not shown) installed in the non-freezing apparatus 2000 can be reduced, thereby freezing the apparatus. The energy efficiency of 2000 can be improved. When the non-freezing device 2000 is in close contact with the cooling device 1000, since there is heat transfer to the cooling device 1000, the heater is operated to maintain the temperature inside the non-freezing device 2000 in a predetermined temperature range. The heat generated by the heater is used to raise the temperature of the inner surface of the cooling apparatus 1000 in close contact with the non-freezing apparatus 2000. Therefore, the installation of the non-freezing device 2000 at intervals from the cooling device 1000 may quickly make the liquid in a supercooled state, and further increase the energy efficiency of the non-freezing device 2000.
도 22는 무동결 장치를 냉장고 도어에 밀착하여 설치한 것과 간격을 두고 설치한 것의 시간에 따른 내부 온도의 변화를 측정한 그래프이다. 그래프에 나타난 바와 같이, 무동결 장치(2000)를 냉각 장치(1000)와 간격을 두고 설치한 경우(밀착도가 낮은 경우), 더 빨리 냉각되었음을 알 수 있다.22 is a graph measuring the change in the internal temperature with time of installing the non-freezing device in close contact with the refrigerator door and at intervals. As shown in the graph, when the non-freezing device 2000 is installed at a distance from the cooling device 1000 (when the adhesion is low), it can be seen that the cooling is faster.
