An ice-making prevention device for a refrigerator.

주지된 바와같이 냉장고는 압축-응축-팽창-증발의 과정을 연속적으로 행하여 냉매를 상태변화시키는 냉동사이클의 원리에 따라 고내의 식품을 냉장 및 냉동시킬 수 있도록 되어 있는 것으로서, 근래에는 상기한 바와같은 단순 냉장 및 냉동기능 이외에도 다양한 기능이 추가된 대용량 복합냉장고의 사용이 증가하고 있는 추세에 있다.As is well known, the refrigerator is capable of refrigeration and freezing of food in the refrigerator according to the principle of the refrigeration cycle in which the refrigerant is changed state by continuously performing compression-condensation-expansion-evaporation. In addition to simple refrigeration and freezing functions, the use of large capacity refrigerators with various functions is increasing.

이러한 대용량 복합냉장고에서 가장 대표적인 부가 기능은 버튼의 누름 동작만으로 냉장고의 외부에서 물과 얼음을 간단하게 취출할 수 있는 디스펜서 기능으로서, 이러한 디스펜서 기능을 갖는 대용량 복합냉장고는 통상적으로 중간의 벽체를 중심으로 좌.우측에 냉동실과 냉장실이 배치 구성된 사이드 바이 사이드(side by side) 방식과, 냉동실이 냉장실의 하부에 위치하고 상기 냉장실은 양문형으로 구성된 바텀 냉동(bottom freezer) 방식이 각각 제안된 바 있다.The most representative additional feature of such a large capacity refrigerator is a dispenser function that allows water and ice to be easily extracted from the outside of the refrigerator by simply pressing a button. A large capacity refrigerator having such a dispenser function is usually centered on an intermediate wall. A side by side method in which a freezer compartment and a refrigerating compartment are arranged on the left and right sides, and a bottom freezer system in which the freezer compartment is located below the refrigerating compartment and have a double door type have been proposed.

도 1은 본원인이 선출원한 바 있는 바텀 타입 냉장고(특허출원 제2003-61411호)를 나타낸 종단면도로서, 그 구성은 냉장실(1)의 하부측에 냉동실(2)이 형성되고, 상기 냉장실(1)은 좌.우측으로 서로 대칭되는 2개의 도어(1a)에 의해서 개폐가 이루어지며, 냉장실(1)의 상부 일측에는 자동제빙기(4)와 아이스 뱅크(5)를 갖는 제빙실(3)이 마련되어 냉장실 도어(1a)의 내측에 형성된 디스펜서(6)에 대한 얼음의 공급이 이루어질 수 있도록 구성되어 있다.Fig. 1 is a longitudinal sectional view showing a bottom type refrigerator (Patent Application No. 2003-61411), which has been filed by the applicant in advance, in which the freezer compartment 2 is formed on the lower side of the refrigerator compartment 1, and the refrigerator compartment ( 1) is opened and closed by two doors 1a which are symmetrical to each other left and right, and an ice maker 3 having an automatic ice maker 4 and an ice bank 5 is provided at an upper side of the refrigerating compartment 1. It is configured to allow the supply of ice to the dispenser 6 formed inside the refrigerating compartment door 1a.

이를 첨부된 도 2를 참조로 하여 좀더 구체적으로 설명하면, 냉장실(1)의 상부측에 자동제빙기(4)와 아이스 뱅크(5)가 내장된 제빙실(3)이 형성되고, 하부측에는 냉동실(2)이 형성되며, 상기 냉동실(2)과 제빙실(3)은 후방측에 제1 증발기(2a)와 제2 증발기(미도시됨)를 각각 포함한다.Referring to this in more detail with reference to FIG. 2, an ice maker 3 having an automatic ice maker 4 and an ice bank 5 is formed in an upper side of the refrigerating chamber 1, and a freezer compartment in a lower side thereof. 2) is formed, and the freezing chamber (2) and the ice making chamber (3) includes a first evaporator (2a) and a second evaporator (not shown) on the rear side.

At this time, the blowing fan 20 is composed of a rearward centrifugal fan 22 for sucking the cold air in the refrigerating chamber and blowing it to the rear side, the grill portion (front) of the rearward centrifugal fan 22 to ensure safety due to exposure of the fan ( 30b) is formed.

그리고, 상기 송풍팬(20)과 제빙실(3)의 사이에는 토출방향이 상기 제빙실(3)측으로 향하는 가이드덕트(30)가 형성되는데, 이때 상기 가이드덕트(30)는 제빙실(3)의 외벽과 평행을 이루는 토출구(30a)를 포함하며, 상기 토출구(30a)는 제빙실의 외벽을 따라 서로 연통하도록 구성된다.In addition, a guide duct 30 is formed between the blower fan 20 and the ice making chamber 3 so that the discharge direction is directed toward the ice making chamber 3 side, wherein the guide duct 30 is the ice making chamber 3. A discharge port 30a parallel to the outer wall of the discharge port 30a, the discharge port 30a configured to communicate with each other along the outer wall of the ice making chamber.

이와같이 구성된 본 발명은 도 5에 도시된 바와같이 후향 원심팬(22)으로 구성된 송풍팬(20)의 작동에 의해서 고내의 냉기가 가이드덕트(30) 측으로 흡입되고, 이 흡입된 냉기는 상기 가이드덕트(30)를 통하여 제빙실의 외벽측으로 송풍되는데, 이때 가이드덕트(30)의 토출구(30a)가 제빙실의 외벽, 즉 열전도판(10)에 대하여 서로 평행하게 형성되어 있어 상기 토출구(30a)를 통하여 토출되는 냉장실의 냉기는 제빙실(3)의 외벽을 따라 후방측에서 전방측으로 송풍 및 순환되는 것이며, 이에 따라 제빙실의 외벽 전체에 걸친 고른 열전달이 이루어질 수 있게 되는 것이다.In the present invention configured as described above, as shown in FIG. 5, the cold air in the refrigerator is sucked into the guide duct 30 by the operation of the blower fan 20 configured as the rearward centrifugal fan 22, and the sucked cold air is guided. Blowing through the 30 to the outer wall side of the ice making chamber, wherein the discharge port 30a of the guide duct 30 is formed in parallel to the outer wall of the ice making chamber, that is, the heat conducting plate 10, so that the discharge port 30a is opened. The cold air of the refrigerating chamber discharged through the air is blown and circulated from the rear side to the front side along the outer wall of the ice making chamber 3, and thus even heat transfer is performed over the entire outer wall of the ice making chamber.

한편, 상기 송풍팬(20)은 후향 원심팬(22) 대신에 흡입방향과 토출방향이 서로 직각을 이루는 축류팬의 적용이 가능하고, 그 설치위치는 냉장실 고내의 어느 위치, 즉 고내의 좌.우측벽 또는 제빙실의 외벽 등에 제한됨이 없이 가능하나, 고내의 공간활용성 및 고내에 저장되는 식품과의 간섭등을 고려할 때 본 발명의 실시예와 같이 냉장실의 후벽측에 매설하는 것이 보다 바람직할 것이다.On the other hand, instead of the rearward centrifugal fan 22, the blowing fan 20 can be applied to the axial flow fan in which the suction direction and the discharge direction are perpendicular to each other, and the installation position is any position in the refrigerator compartment, that is, the left side of the refrigerator. Although not limited to the right wall or the outer wall of the ice making room, it is possible, but considering the space utilization in the interior and the interference with food stored in the interior, it would be more preferable to bury in the rear wall side of the refrigerating chamber as in the embodiment of the present invention. will be.

또한, 제빙실(3)의 외벽을 구성하는 열전도판(10)은 통상 스테인레스 재질로 이루어지나, 이 역시 여기에 국한되는 것은 아니며 그 기능을 수행할 수 있는 것이 면 무방하다.In addition, the heat conduction plate 10 constituting the outer wall of the ice making chamber 3 is usually made of a stainless material, but this is not limited to this, but may be any function that can be performed.

상술한 바와같이 본 발명은 제빙실의 외벽을 열전도율이 우수한 열전도판으로 구성하여 외벽 두께를 최소화하면서 송풍팬을 이용한 냉장실 냉기의 열전달이 이루어질 수 있도록 구성하여 상기 열전도판의 과냉을 방지할 수 있도록 함으로써 제빙실의 콤팩트화를 기할 수 있을 뿐만 아니라 이로인하여 냉잘실 내부의 고내용적 증대에 따른 공간활용의 효율성 및 제품의 질적향상을 기할 수 있는 효과가 있다.As described above, the present invention configures the outer wall of the ice-making chamber as a heat conduction plate having excellent thermal conductivity, thereby minimizing the outer wall thickness, and configured to allow heat transfer of cold air in a refrigerating chamber using a blower fan to prevent overcooling of the heat conduction plate. Not only can the ice making room be compact, but there is an effect that the efficiency of space utilization and the quality of the product can be improved due to the high content of the inside of the cold-jail room.
