Description
본 발명은 소형 냉장고에 관한 것으로, 더욱 상세하게는 열전소자를 이용한 소형 냉장고의 이중 독립칸을 갖는 냉기 순환장치에 관한 것이다.The present invention relates to a small refrigerator, and more particularly to a cold air circulation device having a double independent compartment of a small refrigerator using a thermoelectric element.
일반적으로 냉장고는 냉매파이프를 통해 냉매가 순환되어 냉각작용을 하는 전기식 냉각장치와, 열전소자를 이용하여 열을 방출시키는 전자식 냉각장치로 크게 대별되는 데, 전기식 냉각장치는 냉장고의 하부에 마련되는 기계실에 설치된 압축기와 응축기 및 냉동실의 후방에 마련되는 증발기, 그리고 이들을 상호 연통시키며 소정의 냉매가 순환되는 냉매파이프들로 구성되어진다.In general, a refrigerator is roughly classified into an electric cooler in which a coolant circulates through a coolant pipe and performs cooling, and an electronic cooler in which heat is radiated using a thermoelectric element. The electric cooler is a machine room provided in a lower part of a refrigerator. Compressor and condenser and the evaporator provided in the rear of the freezing chamber, and the refrigerant pipe which communicates with each other and circulates the predetermined refrigerant is installed.
이와 같이 구성된 종래의 일반적인 냉장고는 많은 부속품들로 인해 그 설치공간이 많이 필요하게 되어 냉장고의 부피가 과대해지고, 또한 고장이 발생하였을 때에는 그 수리가 까다로울 뿐만 아니라, 다수의 부품을 제조하고 조립하는 공정이 복잡하기 때문에 냉장고의 제조원가를 상승시키는 문제점이 있다. 또한 상기와 같은 전기식 냉장고에서 냉매로 사용하고 있는 프레온가스 등은 지구의 오존층 파괴를 통한 지구환경오염의 주 원인이 되고 있기 때문에 그 사용이 세계적으로 억제되는 추세이어서 새로운 냉각방식이 요구되어진다.The conventional conventional refrigerator configured as described above requires a lot of installation space due to many accessories, which makes the refrigerator excessively bulky, difficult to repair, and manufactures and assembles a large number of parts. Because of this complexity, there is a problem of raising the manufacturing cost of the refrigerator. In addition, the freon gas used as the refrigerant in the electric refrigerator as described above is the main cause of global environmental pollution through the destruction of the ozone layer of the earth, so its use is being suppressed worldwide, and a new cooling method is required.
상기와 같은 요구를 반영하여 일부 소형냉장고에서 상용화되고 있는 전자식 냉장고가 도 2에 도시되어 있는 바, 이는 냉장고의 후면에 외부케이스와 내부케이스 사이에 소정의 결합수단에 의해 결합되는 열전소자(11)와, 이 열전소자(11)의 일측에 결합되는 알루미늄블럭(10)과, 이 알루미늄블럭(10)의 일측에 접촉되며 냉장고의 내부케이스와 단열벽 사이에 위치되어 냉장고의 내부와 열교환하여 냉각작용을 하는 냉교환기(8)와, 상기 열전소자(11)의 타측에 결합되어 열전소자(11)로 부터 발생되는 열을 외부로 방출시키는 열교환기(9)로 구성된다.Reflecting the needs as described above is an electronic refrigerator commercially available in some small refrigerators are shown in Figure 2, which is a thermoelectric element 11 is coupled to the rear of the refrigerator by a predetermined coupling means between the outer case and the inner case. The aluminum block 10 coupled to one side of the thermoelectric element 11 and the aluminum block 10 are in contact with one side of the thermoelectric element 11 and are located between the inner case of the refrigerator and the heat insulation wall to exchange heat with the inside of the refrigerator for cooling. And a heat exchanger 9 coupled to the other side of the thermoelectric element 11 to discharge heat generated from the thermoelectric element 11 to the outside.
또한 상기한 구성의 열전소자형의 냉기 순환장치는, 고내의 냉기를 냉교환기(8)에서 냉각되도록 배출하기 위한 배출구(14)와, 상기 배출구(14)에서 배출된 공기를 강제 순환하기 위해 내부케이스 외벽에 설치된 송풍팬(4)과, 상기 송풍팬(4)에 의해 냉각된 냉기를 다시 고내의 상부로 유입하기 위한 상류흡입구(16a)와, 고내의 하부로 유입시키기 위한 하류흡입구(16b)로 구성되어진다. In addition, the thermoelectric element-type cold air circulation device having the above-described configuration includes an outlet 14 for discharging cold air in the refrigerator to be cooled by the cold exchanger 8 and an internal portion for forcibly circulating air discharged from the outlet 14. A blowing fan 4 provided on the outer wall of the case, an upstream suction port 16a for introducing the cool air cooled by the blowing fan 4 back to the upper part of the furnace, and a downstream suction port 16b for introducing the lower part of the furnace It consists of.
상기와 같은 종래의 전자식 냉장고는 상기 열전소자(11)에 전류를 인가시키면 이 전류의 흐름이 열류를 유발시킴으로써 즉, 상기 열전소자(11)에 의해 낮은 온도부인 냉교환기(8)로 부터 높은 온도부인 열교환기(9)로 열을 펌핑(pumping)하게 됨으로써, 고내의 온도를 낮게 유지하여 냉각작용을 하게 되는 것이다.In the conventional electronic refrigerator as described above, when a current is applied to the thermoelectric element 11, the flow of the current causes a heat flow, that is, a high temperature from the cold exchanger 8, which is a low temperature portion by the thermoelectric element 11. By pumping heat into the denier heat exchanger (9), the cooling is performed by keeping the temperature in the furnace low.
그런데, 상기와 같은 종래의 전자식 냉장고는 한 개의 공간을 가지고 있으므로 공간 활용도가 낮다는 결점이 있다. 예를 들어 화장품 냉장고, 과일이나 식품의 냉장을 위해서는 소형 냉장고가 다수개 있어야 한다는 단점이 있다.However, the conventional electronic refrigerator as described above has a disadvantage that space utilization is low because it has one space. For example, cosmetic refrigerators, there is a disadvantage that a plurality of small refrigerators for refrigeration of fruits or food.
따라서 본 발명의 목적은 상기한 바와 같은 종래 기술의 문제점을 해결하기 위한 것으로 별도의 이중 독립칸을 형성시켜 한개의 냉장고로 2개의 냉장고 역할을 수행하도록 구성시키고, 이러한 이중 독립칸을 냉각하기 위한 냉기의 순환장치를 제공하는데 있다.Therefore, an object of the present invention is to solve the problems of the prior art as described above to form a separate double independent compartment to perform the role of two refrigerators in one refrigerator, cold air for cooling the double independent compartment To provide a circulator.

이하 본 발명에 의한 소형냉장고의 에어플로장치에 관한 바람직한 실시예를 첨부된 도면을 참고하여 상세하게 설명한다.Hereinafter, a preferred embodiment of an airflow apparatus for a small refrigerator according to the present invention will be described in detail with reference to the accompanying drawings.
도 3은 본 발명에 의한 소형냉장고의 사시도이고, 도 4는 본 발명에 의한 에어플로장치의 단면도를 도시하고 있다.Figure 3 is a perspective view of a small refrigerator according to the present invention, Figure 4 shows a cross-sectional view of the airflow apparatus according to the present invention.
열전소자형 냉장고는 냉장고의 후면에 외부케이스(21)와 내부케이스(22) 사이에 소정의 결합수단에 의해 결합되는 열전소자(31)와, 이 열전소자(31)의 일측에 결합되는 알루미늄블럭(30)과, 이 알루미늄블럭(30)의 일측에 접촉되며 냉장고의 내부케이스(22)와 단열벽(25) 사이에 위치되어 냉장고의 내부와 열교환하여 냉각작용을 하는 냉교환기(28)와, 상기 열전소자(31)의 타측에 결합되어 열전소자(31)로 부터 발생되는 열을 외부로 방출시키는 열교환기(29)로 구성된다.The thermoelectric refrigerator includes a thermoelectric element 31 coupled to a rear side of the refrigerator by a predetermined coupling means between the outer case 21 and the inner case 22 and an aluminum block coupled to one side of the thermoelectric element 31. 30 and a cold exchanger 28 in contact with one side of the aluminum block 30 and positioned between the inner case 22 and the heat insulation wall 25 of the refrigerator to exchange heat with the inside of the refrigerator for cooling; Is coupled to the other side of the thermoelectric element 31 is composed of a heat exchanger 29 for dissipating heat generated from the thermoelectric element 31 to the outside.
상기와 같이 구성된 전자식 냉장고의 냉각 효율을 높이기 위한 방열 구조를 설명하면, 냉교환기(28)측에서 생긴 응결수를 배수호스(37)를 통해 열교환기(29)의 하부에 있는 물받이(36)에 집수되고, 이 집수된 물은 열교환기(29)의 폐열에 의해 자연 증발이 되어 외부케이스의 저부에 형성된 하배기구(33a)을 통해 배기되며, 또한 외부케이스(21)의 하단부 외측에 돌설된 스페이스(39)에 의해 외부케이스(21)가 설치벽면과는 이격되게 되어 흡기구(32) 및 배기구(33,33a)를 통한 공기 흐름이 원할하며, 방열팬덕트(38)에 의해 공기 흡입력이 증가되어 방열효과가 극대화될 뿐만 아니라 냉각효과도 증대된다.

The outer case 21 is spaced apart from the installation wall by the 39 so that air flow through the inlet 32 and the exhaust ports 33 and 33a is desired, and the air suction force is increased by the heat radiating fan duct 38. The heat dissipation effect is not only maximized, but also the cooling effect is increased.
냉장고의 공간 활용도를 높이기 위한 이중 독립칸의 소형 냉장고 구성은, 상부칸(20a)과 하부칸(20)을 구분하는 중간벽(41)이 형성되어 있으며, 상기 중간벽(41)의 일부에는 상부칸(20a)의 냉기가 하부칸(20)으로 보내기 위한 냉기통공부(42)가 형성되어 있다. 상기 냉기 통공부(42)는 중간벽의 양측면부나 후면부에 형성하는 것이 냉장물을 중간벽위에 적재하였을 경우 통공에 방해가 되지 않아 이상적이다. 이러한 이중 독립칸 냉장고의 냉각효율을 높이기 위한 냉기 순환장치는, 고내의 공기를 냉교환기(28)에서의 냉각을 위해 냉교환기(28)측으로 배출시키기 위한 배출구(34)가 내부케이스(22)의 뒤쪽에 형성되어 있고, 배출구(34)와 직면하여 내부케이스(22)의 외부에는 냉기를 순환시키기 위한 송풍팬(24)이 설치되며, 상기 송풍팬(24)으로 배출된 공기는 냉교환기(28)에 의해 냉각되어 상부칸(20a)으로 유입되도록 안내하는 상류덕트(35a)와, 상류덕트(35a)의 단부 및 상부칸(20a)의 천정부위에 형성된 상류흡입구(43a)와, 배출된 공기가 하부칸(20)으로 유입되도록 안내하는 하류덕트(35b)와, 그리고 상기 하류덕트(35b)의 단부 및 하부칸(20)의 배면하부에 형성된 하류흡입구(43b)로 구성되어 있다.In the small refrigerator configuration of the double independent compartment to increase the space utilization of the refrigerator, an intermediate wall 41 separating the upper compartment 20a and the lower compartment 20 is formed, and a part of the intermediate wall 41 has an upper portion.
