Description

냉온장고{Cool ＆ hot storage chamber}Hot and cold storage {Cool & hot storage chamber}

본 발명은 냉온장고에 관한 것으로, 더욱 상세하게는 열전소자를 이용하여 냉장 및 온장 기능을 수행할 수 있는 냉온장고에 관한 것이다.The present invention relates to a cold and hot refrigerator, and more particularly to a cold and cold refrigerator that can perform the refrigerating and warming function using a thermoelectric element.

일반적으로 냉장고는 냉동사이클의 증발기에서 생성된 냉기를 캐비닛내의 저장실로 공급하여 각종식품의 신선도를 장기간 유지할 수 있도록 구성되어 있다. 그러나, 이러한 냉장고는 냉동 및 냉장기능만을 수행할 수 있으며, 냉동사이클을 이루기 위해 응축기와 증발기 및 압축기 등 많은 구성요소가 요구되는 단점이 있다.In general, the refrigerator is configured to supply the cool air generated in the evaporator of the refrigeration cycle to the storage compartment in the cabinet to maintain the freshness of various foods for a long time. However, such a refrigerator may perform only a refrigerating and refrigerating function, and many components such as a condenser, an evaporator, and a compressor are required to achieve a refrigeration cycle.

이러한 것을 해소하기 위해 최근에는 열전소자를 이용하여 온장 및 냉장기능을 병행할 수 있는 냉온장고가 개시되어 있는데, 이것은 저장공간이 형성된 캐비닛과, 저장공간을 개폐하는 도어와, 캐비닛의 소정부위에 부착된 열전소자를 갖추고 있다.In order to solve this problem, recently, a cold / cold storage apparatus capable of performing both heating and refrigeration functions by using a thermoelectric element has been disclosed. Equipped thermoelectric element.

열전소자는 펠티어 소자의 일종으로, 이중 접합된 금속판에 직류 전원을 가해주면 한쪽 면은 전자가 주위로부터 열에너지를 흡수하는 흡열 현상이 일어나고(차가워짐), 또 반대측 면은 전자의 열에너지 방출에 의해서 발열이 일어나게 된다(뜨거워짐).Thermoelectric element is a kind of Peltier element. When DC power is applied to the double-bonded metal plate, one side of the thermoelectric element absorbs heat energy from the surroundings (cold), and the other side generates heat by emitting the thermal energy of electrons. This happens (heats up).

따라서 열전소자를 한쪽 면이 저장공간을 향하도록 배치하여, 여기에 직류 전원의 극성을 교환함에 따라 냉기 또는 열기를 발생시킬 수 있게 된다.Therefore, by arranging the thermoelectric element so that one surface thereof faces the storage space, cold or hot air can be generated by exchanging the polarity of the DC power supply thereto.

즉, 열전소자에 직류 전원이 인가됨에 따라 이의 한쪽 면에서 열이 방출되어 저장실 온도를 상승시킴으로써, 냉온장고를 온장고로 사용할 수 있다. 반면에, 열전소자에 인가되는 직류 전원의 극성을 변경하면, 반대로 열전소자의 한쪽 면이 냉각되어 저장실 온도를 낮춤으로써, 냉온장고를 냉장고로 사용할 수 있다.That is, when a direct current power is applied to the thermoelectric element, heat is released from one surface thereof to increase the storage temperature, thereby enabling the use of a cold / heat storage cabinet as a warmer. On the other hand, if the polarity of the DC power applied to the thermoelectric element is changed, on the contrary, one side of the thermoelectric element is cooled to lower the storage temperature, so that a cold / hot refrigerator can be used as a refrigerator.

그러나, 이러한 종래 열전소자를 이용한 냉온장고는 저장실이 하나인 관계로냉장고 또는 온장고 기능만을 수행할 수 있다. 즉, 냉장고로 사용할 경우에는 온장고 기능을, 온장고로 사용할 경우에는 냉장고 기능을 전혀 수행할 수 없는 단점이 있다.However, since the conventional cold and cold storage using a thermoelectric element has only one storage compartment, it can perform only a refrigerator or a warmer function. In other words, when used as a refrigerator, a warmer function is used, and when used as a warmer, a refrigerator function cannot be performed at all.

본 발명은 이러한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 캐비닛내의 저장공간을 복수의 저장실로 구획하여 냉장 및 온장 기능을 동시 또는 별개로 수행할 수 있는 냉온장고를 제공하는 것이다.The present invention is to solve this problem, it is an object of the present invention to provide a cold storage compartment that can perform the refrigerating and warming function simultaneously or separately by partitioning the storage space in the cabinet into a plurality of storage compartments.

또한, 본 발명의 또 다른 목적은 복수의 저장실을 동시 또는 별도로 개폐할 수 있도록 도어 구조를 개선하여 사용 편리성을 보다 향상시킬 수 있는 냉온장고를 제공하는 것이다.In addition, another object of the present invention is to provide a cold and cold storage that can further improve the convenience of use by improving the door structure to open or close a plurality of storage compartments simultaneously or separately.

이하, 본 발명에 따른 바람직한 실시 예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 따른 열전소자를 이용한 냉온장고는 도 1과 도 2에 도시한 바와 같이, 식품을 저장하기 위해 저장공간(21)(22)이 형성된 함체(函體) 모양의 캐비닛(10)과, 캐비닛(10)에 힌지 결합되어 저장공간(21)(22)을 개폐하는 도어(50)를 구비한다.Cold and cold storage using a thermoelectric element according to the present invention, as shown in Figures 1 and 2, the cabinet-shaped cabinet 10 is formed with a storage space (21, 22) for storing food, A door 50 is hinged to the cabinet 10 to open and close the storage spaces 21 and 22.

캐비닛(10)은 전면부가 개방된 저장공간(21)(22)을 형성하기 위한 내부케이스(11)와, 이 내부케이스(11) 후벽에 배치되며 그 자체에서 발열 및 흡열기능을 수행할 수 있는 열전소자(41)(42)와, 내부케이스(11)를 감싸도록 결합되는 외부케이스(12)를 포함하며, 내부케이스(11)와 외부케이스(12) 사이에는 저장공간(21)(22)을 외부와 단열시키기 위한 단열벽(미도시)이 마련된다.The cabinet 10 has an inner case 11 for forming the storage spaces 21 and 22 with an open front portion, and is disposed on the rear wall of the inner case 11 and can perform heat and endothermic functions on its own. It includes a thermoelectric element 41, 42, and an outer case 12 coupled to surround the inner case 11, the storage space 21, 22 between the inner case 11 and the outer case 12 A heat insulation wall (not shown) is provided to insulate the heat from the outside.

외부케이스(12)는 금속판으로 벤딩 구성되며 우레탄 발포액이 주입될 수 있도록 내부케이스(11)와 사이틈이 유지되게 결합된다. 그리고 내부케이스(11)는 열전소자(41)(42)의 열전도율을 높이기 위해 알루미늄으로 구성하는 것이 바람직하다. 미설명부호 "13"은 캐비닛(10) 상면에 배치된 제어패널로서, 여기에는 다수의 조작버튼과, 저장공간(21)(22)의 온도제어 프로그램이 내장된 회로기판이 장착된다.The outer case 12 is configured to be bent by a metal plate and is coupled to maintain the gap between the inner case 11 and the urethane foam liquid can be injected. And the inner case 11 is preferably composed of aluminum in order to increase the thermal conductivity of the thermoelectric elements (41, 42). Reference numeral "13" denotes a control panel disposed on the upper surface of the cabinet 10, in which a plurality of operation buttons and a circuit board on which the temperature control programs of the storage spaces 21 and 22 are incorporated are mounted.

또한, 캐비닛(10)내의 저장공간은 제1저장실(21)과 제2저장실(22)로 구획된다. 제1저장실(21)과 제2저장실(22)은 소정의 두께를 갖는 직사각형 판상의 중간격벽(30)에 의해 상하로 구획되는데, 이는 냉장 및 온장 기능을 동시 또는 별개로 수행할 수 있도록 하기 위함이다. 즉, 상하로 구획된 제1저장실(21)과 제2저장실(22)을 같은 용도로 사용할 수 있고, 냉장실과 온장실 또는 반대로 온장실과 냉장실로 달리하여 사용할 수 있게 된다. 그리고 중간격벽(30)은 캐비닛(10)으로부터 착탈 가능하게 조립되는데, 이것은 제1저장실(21)과 제2저장실(22)이 같은 용도로 사용될 경우 제거하여 저장공간을 보다 효율적으로 활용하기 위함이다. 이를 위해 내부케이스(11) 양측벽에는 중간격벽(30)의 양측단(30L)(30R)이 미끄러져 결합되도록 한 쌍의 레일(31)이 대칭되게 마련된다. 따라서 한 쌍의 레일(31)을 따라 중간격벽(30)을 가로방향으로 설치하면, 저장공간이 제1저장실(21)과 제2저장실(22)로 상하 구획됨과 동시에 중간격벽(30)은 선반 기능을 수행할 수 있게 된다.In addition, the storage space in the cabinet 10 is divided into a first storage chamber 21 and a second storage chamber 22. The first storage chamber 21 and the second storage chamber 22 are divided up and down by a middle plate 30 of a rectangular plate having a predetermined thickness, so that the refrigerating and warming functions can be performed simultaneously or separately. to be. That is, the first storage compartment 21 and the second storage compartment 22 partitioned up and down can be used for the same purpose, and can be used differently as a refrigerating compartment and a heating compartment or, conversely, a heating compartment and a refrigerating compartment. In addition, the intermediate partition 30 is detachably assembled from the cabinet 10, which is to remove the first storage chamber 21 and the second storage chamber 22 when they are used for the same purpose, so as to effectively use the storage space. . To this end, a pair of rails 31 are symmetrically provided on both side walls of the inner case 11 so that both side ends 30L and 30R of the intermediate partition 30 slide together. Therefore, when the intermediate partition 30 is installed in the horizontal direction along the pair of rails 31, the storage space is partitioned vertically into the first storage chamber 21 and the second storage chamber 22, and the intermediate partition 30 is a shelf. You will be able to perform the function.

열전소자(41)(42)는 반도체(또는 도체)에 전류가 흐르면 반도체 캐리어에 의해 일측 면이 차가워지면서 다른 측면이 더워지는 펠티어(Peltier) 소자로서, 인가되는 전류 방향에 따라 제1저장실(21)과 제2저장실(22) 온도를 쉽게 변화시킬 수 있도록 내부케이스(11) 후면에 밀착 설치된다. 이러한 열전소자는 제1저장실(21)측 후벽에 배치된 제1열전소자(41)와, 제2저장실(22)측 후벽에 배치된 제2열전소자(42)로 이루어진다. 이에 따라 제1열전소자(41)와 제2열전소자(42)에 인가되는 전류방향을 달리 하면 제1저장실(21)과 제2저장실(22)은 각기 다른 용도(냉장실과 온장실 또는 온장실과 냉장실)로 사용되며, 인가 전류방향을 동일하게 하면 제1저장실(21)과 제2저장실(22)은 같은 용도(모두 온장실 또는 냉장실)로 사용할 수 있게 된다.The thermoelectric elements 41 and 42 are Peltier elements in which one side is cooled by the semiconductor carrier and the other side is warmed when a current flows through the semiconductor (or conductor). The first storage chamber 21 is used according to the direction of the applied current. ) And the second storage compartment 22 is installed in close contact with the rear of the inner case 11 so that the temperature can be easily changed. The thermoelectric element includes a first thermoelectric element 41 disposed on the rear wall of the first storage chamber 21 and a second thermoelectric element 42 disposed on the rear wall of the second storage chamber 22. Accordingly, when the current directions applied to the first thermoelectric element 41 and the second thermoelectric element 42 are different from each other, the first storage chamber 21 and the second storage chamber 22 have different uses (such as a refrigerator compartment, a warm room, or a warm room). When the applied current direction is the same, the first storage chamber 21 and the second storage chamber 22 can be used for the same purpose (both in a warm room or a refrigerator compartment).

그리고 도 3을 참조하면, 도어(50)는 제1저장실(21)과 제2저장실(22)을 동시에 개폐하기 위한 메인도어(51)와, 이 메인도어(51)에 마련되어 제1저장실(21)과 제22저장실(22)을 별도로 개폐하기 위한 복수의 서브도어(52)(53)를 포함한다.3, the door 50 includes a main door 51 for simultaneously opening and closing the first storage chamber 21 and the second storage chamber 22, and a first storage chamber 21 provided in the main door 51. ) And a plurality of sub-doors 52, 53 for opening and closing the twenty-second storage chamber 22 separately.

In addition, a gasket 51c of an elastic material having a magnet (not shown) embedded therein is disposed on a rear surface of the main door 51. Accordingly, when the main door 51 is closed, the gasket 51c is in close contact with the front surface of the cabinet 10, so that the storage spaces 21 and 22 are sealed. In addition, the first opening part 51a and the second opening part 51b are formed in the main door 51 so that the first storage chamber 21 and the second storage chamber 22 communicate with the outside. The first opening portion 51a communicates with the first storage chamber 21, and the second opening portion 51b is provided above and below the main door 51 so as to communicate with the second storage chamber 22.

그리고 서브도어는 제1개방부(51a)를 개폐하는 제1서브도어(52)와, 제2개방부(51b)를 개폐하는 제2서브도어(53)를 포함하며, 이들의 일측단 상하부는 좌우 방향으로 회전 운동할 수 있도록 메인도어(51)의 개방부(51a)(51b) 일측에 각각 힌지 결합된다. 즉, 제1서브도어(52)와 제2서브도어(53)는 메인도어(51)에서 제1개방부(51a) 및 제2개방부(51b)를 별도로 개폐하게 된다.The subdoor includes a first subdoor 52 that opens and closes the first opening part 51a, and a second sub door 53 that opens and closes the second opening part 51b. The hinges are coupled to one side of the opening portions 51a and 51b of the main door 51 so as to rotate in the left and right directions. That is, the first sub-door 52 and the second sub-door 53 open and close the first open part 51a and the second open part 51b separately from the main door 51.

이 제1,2서브도어(52)(53) 배면에도 역시 가장자리를 따라 자석이 내장된 가스킷(55)이 부착되어 있어서, 인위적인 힘을 가하지 않은 상태에서는 닫힘 상태가 그대로 유지되게 된다. 또한, 도 1의 도어(50)에 표시된 미설명부호 "54"는 제1,2서브도어(52)(53)의 "손잡이"로서, 이를 잡고서 제1,2서브도어(52)(53)를 개폐 작동시킬 수 있다.A gasket 55 having a magnet built therein is also attached to the rear surfaces of the first and second sub doors 52 and 53 so that the closed state is maintained as it is without artificial force. In addition, the reference numeral "54" shown in the door 50 of Figure 1 is a "handle" of the first and second sub-doors 52, 53, holding the first and second sub-doors 52, 53 Can be opened and closed.

한편, 제1,2서브도어(52)(53)를 메인도어(51)의 개방부(51a)(51b) 일측에 힌지결합하는 것으로 설명하였지만, 이에 국한하지 않고, 이들을 메인도어(51)와 함께 캐비닛(10)의 전면 일측에 마련된 상하 힌지(14)를 통해 결합할 수 도 있다.Meanwhile, the first and second sub doors 52 and 53 are hinged to one side of the opening portions 51a and 51b of the main door 51, but the present invention is not limited thereto. Together with the upper and lower hinges 14 provided on the front side of the cabinet 10 may be coupled together.

또한, 본 발명의 실시 예에서 제1,2서브도어(52)(53)를 좌우 개폐식으로 설치된 것으로 설명하였으나, 도 4에 도시한 바와 같이, 제1,2서브도어(52)(53)를 각각 링크장치(56)를 통해 상하 개폐방식으로 설치하여도 본 발명의 소기 목적을 달성할 수 있음은 물론이다.In addition, in the embodiment of the present invention, the first and second sub doors 52 and 53 have been described as being installed in a left and right opening and closing manner, as shown in FIG. 4, the first and second sub doors 52 and 53 may be Of course, even if installed in the vertical opening and closing method through the link device 56 can achieve the desired purpose of the present invention.

다음에는 이와 같이 구성된 본 발명에 따른 냉온장고의 사용상태 및 이에 따른 작용효과를 설명한다.Next, the use state of the cold and hot refrigerator according to the present invention configured as described above and the effect thereof will be described.

먼저, 캐비닛(10)내에 중간격벽(30)을 설치하여 저장공간을 제1저장실(21)과 제2저장실(22)로 구획하며, 제어패널(13)을 통해 제1열전소자(41)와 제2열전소자(42)에 각각 반대 직류전원을 인가한 경우를 설명한다.First, the intermediate partition 30 is installed in the cabinet 10 to divide the storage space into the first storage chamber 21 and the second storage chamber 22, and the first thermoelectric element 41 and the control panel 13 through the control panel 13. A case in which opposite DC power sources are respectively applied to the second thermoelectric elements 42 will be described.

이러한 상태에서는 제1열전소자(41) 한쪽 면에서의 흡열작용에 의해 제1저장실(21)은 냉장실로, 제2열전소자(42) 한쪽 면에서의 발열작용에 의해 제2저장실(22)은 온장실로 유지된다. (한편, 전류의 방향을 바꾸어 준다면 흡입과 발열이 바뀌어서 일어나기 때문에, 제1저장실(21)은 온장실로 제2저장실(22)은 냉장실로 사용할 수 있다.) 따라서 제1저장실(21)에 보관된 식품은 차가운 상태로 유지되며, 제2저장실(22)에 보관된 식품은 뜨거운 상태로 유지된다.In this state, the first storage chamber 21 is a refrigerating chamber by the endothermic action on one side of the first thermoelectric element 41, and the second storage chamber 22 is heated by the exothermic action on one side of the second thermoelectric element 42. It is kept in the greenhouse. (On the other hand, if the direction of the current is changed, the suction and the heat are changed, so that the first storage chamber 21 can be used as a heating chamber and the second storage chamber 22 can be used as a cold compartment.) Therefore, the first storage chamber 21 The food is kept cold, and the food stored in the second storage compartment 22 is kept hot.

그리고 도 5에 도시한 바와 같이, 제1서브도어(52)와 제2서브도어(53)를 별개로 개방하여 제1저장실(21)과 제2저장실(22)에서 식품을 꺼내거나 여기에 수납할 수 있다. 이로 인해 냉장실로 사용되는 제1저장실(21) 개폐작동 시 제2저장실(22)에서의 온기 유출이 방지되며, 온장실로 사용되는 제2저장실(22) 개폐작동 시 제1저장실(21)에서의 냉기 유출이 방지됨으로써, 제1열전소자(41)와 제2열전소자(42) 소비전력을 보다 절감할 수 있다.As shown in FIG. 5, the first subdoor 52 and the second sub door 53 are separately opened to take out or store food in the first storage chamber 21 and the second storage chamber 22. can do. This prevents the outflow of warmth from the second storage compartment 22 during the opening and closing operation of the first storage compartment 21 used as the refrigerating compartment and from the first storage compartment 21 during the opening and closing operation of the second storage compartment 22 used as the warming compartment. By preventing the leakage of cold air, power consumption of the first thermoelectric element 41 and the second thermoelectric element 42 may be further reduced.

또한, 제1열전소자(41)와 제2열전소자(42)에 인가되는 전류 방향을 바꾸어 준다면, 앞에서 기술한 바와 같이, 제1저장실(21)을 온장실로, 제2저장실(22)을 냉장실로 사용할 수 있는데, 이 경우에도 동일한 효과를 발휘하기 때문에 이에 대한 설명은 생략한다.In addition, if the current directions applied to the first thermoelectric element 41 and the second thermoelectric element 42 are changed, as described above, the first storage chamber 21 is a warm room and the second storage chamber 22 is a cold room. In this case, since the same effect is exhibited, a description thereof will be omitted.

다음에는 제1열전소자(41)와 제2열전소자(42)에 동일한 방향의 직류전원을 인가하는 경우를 설명한다.Next, a case where a direct current power source in the same direction is applied to the first thermoelectric element 41 and the second thermoelectric element 42 will be described.

이 경우에는 제1열전소자(41)와 제2열전소자(42)에 동일한 방향의 전류가 인가되어 제1,2열전소자(41)(42) 한쪽 면에서 모두 발열작용이 일어나기 때문에, 제1저장실(21)과 제2저장실(22)은 모두 온장실로 사용된다. (한편, 전류의 방향을 바꾸어 준다면 흡입과 발열작용 면이 바뀌기 때문에, 제1저장실(21)과 제2저장실(22)은 모두 냉장실로 사용할 수 있다.)In this case, since the current in the same direction is applied to the first thermoelectric element 41 and the second thermoelectric element 42, heat generation occurs on both sides of the first and second thermoelectric elements 41 and 42. The storage chamber 21 and the second storage chamber 22 are both used as a warm room. (On the other hand, if the direction of the electric current is changed, the suction and heat generating surfaces change, so that both the first storage chamber 21 and the second storage chamber 22 can be used as a refrigerating chamber.)

이 때, 보관식품의 양이 많거나 사이즈가 큰 경우에는 중간격벽(30)을 분리하여 수납한다. 즉, 중간격벽(30)을 분해하면 제1저장실(21)과 제2저장실(22)이 통합되며, 이로 인해 사이즈가 큰 것은 물론이며 보다 많은 양을 한꺼번에 수납할 수 있다.At this time, when the amount of stored food is large or the size is large, the intermediate partition 30 is stored separately. That is, when the intermediate partition 30 is disassembled, the first storage chamber 21 and the second storage chamber 22 are integrated, thereby allowing a large amount and a larger amount to be stored at once.

아울러, 이러한 경우에는 도 6에 도시한 바와 같이, 메인도어(51)의 손잡이(51d)를 잡고 이를 개방시키면, 저장공간(21)(22) 전체가 개방되어 식품 인출 및 수납을 보다 용이하게 할 수 있다.In addition, in such a case, as shown in FIG. 6, when the handle 51d of the main door 51 is held and opened, the entire storage spaces 21 and 22 are opened to facilitate food withdrawal and storage. Can be.

한편, 제1열전소자(41) 및 제2열전소자(42)에 인가되는 전류 방향을 바꾸어 준다면, 앞에서 기술한 바와 같이, 제1저장실(21)과 제2저장실(22)을 모두 냉장실로 사용할 수 있다.On the other hand, if the current direction applied to the first thermoelectric element 41 and the second thermoelectric element 42 is changed, as described above, both the first storage chamber 21 and the second storage chamber 22 can be used as a refrigerating chamber. Can be.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 냉온장고에 의하면, 캐비닛에는 냉장 및 온장 기능을 동시 또는 별개로 수행할 수 있도록 저장공간을 제1저장실과 제2저장실로 구획하는 격벽이 마련되며, 도어는 제1저장실과 제2저장실을 동시에 개폐하는 메인도어와, 메인도어에 배치되며 제1저장실과 제2저장실을 개폐하기 위한 서브도어를 구비하고 있다. 이에 따라 복수의 저장실을 통해 냉장 및 온장 기능을 동시 또는 선택적으로 수행할 수 있기 때문에, 기능성 및 사용 편리성을 보다 향상시킬 수 있으며, 아울러 메인도어와 서브도어를 통해 복수개의 저장실을 동시 또는 별도로 개폐할 수 있어서 각 저장실에서의 냉기 및 열기 유출을 최소화할 수 있는 작용효과가 있다.As described above in detail, according to the cold and cold storage cabinet according to the present invention, the cabinet is provided with partition walls for partitioning the storage space into the first storage compartment and the second storage compartment so as to simultaneously or separately perform the refrigerating and warming function, the door The main door has a main door for simultaneously opening and closing the first storage compartment and the second storage compartment, and a subdoor disposed in the main door for opening and closing the first storage compartment and the second storage compartment.
