본 고안은 냉장고의 냉장실 냉기공급장치에 관한 것으로, 특히 냉동실루버의 표면에 발생되는 이슬맺힘현상 및 착상현상을 방지함은 물론 냉장실로의 냉기공급이 원활히 이루어져 냉장실에 수납된 저장물의 냉각효율을 향상시키도록 한 냉장고의 냉장실 냉기공급장치에 관한 것이다.The present invention relates to a refrigerator cold air supply device of the refrigerator, in particular, to prevent dew condensation and frost phenomenon on the surface of the freezing chamber as well as to smoothly supply the cold air to the refrigerator compartment to improve the cooling efficiency of the storage stored in the refrigerator compartment. It relates to a cold room cold air supply device of the refrigerator.
일반적인 냉장고는 첨부도면 제1도에 도시한 바와 같이 냉동실(10) 후방에 위치된 증발기(60)에서 생성된 냉기가 증발기(60)의 상방에 위치된 냉기송풍팬(30)에 의하여 강제됨에 따라 냉동실(10)로는 루버절연물(80)의 냉기토출공과 냉동실루버(70)의 냉기토출공을 통하여 공급되어지고, 냉장실(20)로는 냉기공급덕트(90)를 통하여 유도되어 공급되도록 한 구성으로 이루어져 있으며, 첨부도면 제2도에 도시한 바와 같이 소위 '2팬 방식'이라 하여 냉동실용 냉기송풍팬(40)과 냉장실용 냉기송풍팬(50)을 별개로 구비한 냉장고의 루버절연물(80)은 냉동실용 냉기송풍팬(40)의 벨마우스부(82)와 냉장실용 냉기송풍팬(50)의 벨마우스부(84)가 형성되어 있으며, 냉장실용 냉기송풍팬(50)의 벨마우스부(84) 일측으로는 냉장실(20)로의 냉기공급을 위한 냉기공급덕트(90)의 입구측단이 후방지향으로 연장형성되어 있다.As shown in FIG. 1 of the accompanying drawings, a common refrigerator is forced by the cold air blower fan 30 positioned above the evaporator 60 as the cold air generated in the evaporator 60 positioned behind the freezer compartment 10 is forced. The freezing chamber 10 is supplied through the cold air discharge hole of the louver insulator 80 and the cold air discharge hole of the freezing chamber 70, and is configured to be guided and supplied to the refrigerating chamber 20 through the cold air supply duct 90. As shown in FIG. 2, the louver insulator 80 of the refrigerator having a freezing air cooling fan 40 for a freezer compartment and a cold air cooling fan 50 for a refrigerating compartment is separately provided. A bell mouse portion 82 of the cold air blowing fan 40 for the freezer compartment and a bell mouse portion 84 of the cold air blowing fan 50 for the refrigerating compartment are formed, and a bell mouse portion 84 of the cold air blowing fan 50 for the refrigerating compartment. ) One side of the inlet side of the cold air supply duct 90 for cold air supply to the refrigerating chamber 20 The stage extends backwardly.
그런데 종래에 제공된 통상적인 '2팬 방식' 냉장고의 냉장실 냉기공급장치는 단순히 냉장실용 냉기송풍팬(50)에 의하여 강제되는 냉기가 루버절연물(80)의 후방지향으로 연장형성된 냉기공급덕트(90)의 입구측단을 통하여 유도되어 냉장실(20)로 공급되도록 구성되어 있으므로, 냉동실용 냉기송풍팬(40)이 구동중단되고 냉장실용 냉기송풍팬(50)만이 구동될 경우에는 냉기의 역류현상으로 인하여 냉동실(10)내의 온도상승된 냉기가 냉동실루버(70)의 표면에 접하게 됨에 따라 냉동실루버(70)를 경계로 한 양측의 온도편차에 의하여 냉동실루버(70)의 표면에는 이슬맺힘현상 및 착상현상이 발생됨과 아울러, 루버절연물(80)의 후방지향으로 연장형성된 냉기공급덕트(90)의 입구측단을 통하여 유도되는 냉기의 흐름이 냉기공급덕트(90)의 입구측단에서 저항을 받아 냉장실(20)로 원활히 유도되지 못함으로써 냉장실(20)내에 수납된 저장물의 냉각효율이 저하되는 문제점이 있었다.However, the refrigerator compartment cold air supply device of the conventional 'two fan type' refrigerator provided in the related art is a cold air supply duct 90 in which cold air forced by the cold air supply fan 50 for the cold room is extended toward the rear of the louver insulator 80.

제3도, 제4도 및 제5도를 참조하여 설명하면, 냉동실(10)의 후측에 냉동실루버(70)와 루버절연물(80)이 각각 설치되어 냉동실(10)과 냉각기실을 분리 구획된다.Referring to FIGS. 3, 4, and 5, the freezing chamber 70 and the louver insulator 80 are respectively installed at the rear side of the freezing chamber 10 to separate and separate the freezing chamber 10 and the cooling chamber. .
상기 루버절연물(80)은 냉각기실의 냉기를 냉동실(10) 및 냉장실(20)로 공급하기 위한 냉기 통로인 원형의 냉기토출공을 그 상측에 구비된다.The louver insulator 80 is provided with a circular cold air discharge hole that is a cold air passage for supplying cold air of the cooler chamber to the freezing chamber 10 and the refrigerating chamber 20.
상기 냉기토출공의 후측에는 냉장실용 냉기송풍팬(50)이 위치된다.The cold air blowing fan 50 for the refrigerating chamber is located at the rear side of the cold air discharge hole.
한편, 상기 냉장실용 냉기송풍팬(50)에 의하여 강제되는 냉기의 흐름이 냉동실루버(70) 표면을 따라서 후술할 냉기공급덕트(90)로 유도되도록 냉장실용 냉기송풍팬(50)의 벨마우스부(84) 즉, 루버절연물(80)의 원형의 냉기토출공 전면 하부에는 종측 길이방향으로 냉기를 냉장실(20)로 안내하는 한쌍의 비이드(86)(88)가 형성된다.On the other hand, the bellows portion of the cold air cooling fan 50 for the refrigerating compartment so that the flow of cold air forced by the cold air cooling fan 50 for the refrigerating compartment is led to the cold air supply duct 90 to be described later along the surface of the freezing chamber 70. That is, a pair of beads 86 and 88 for guiding the cold air to the refrigerating chamber 20 in the longitudinal longitudinal direction are formed at the lower portion of the front surface of the circular cold air discharge hole of the louver insulator 80.
그리고 양측 비이드(86)(88) 사이의 루버절연물(80) 전면에는 상기 냉기통공(87)을 통한 냉기의 흐름이 원활히 이루어지도록 일정간격으로 다수의 돌출턱(89)이 형성된다.In addition, a plurality of protruding jaws 89 are formed on the front surface of the louver insulator 80 between the two beads 86 and 88 at regular intervals so that the cool air flows smoothly through the cold air hole 87.
한편, 상기 냉장실용 냉기송풍팬(50)의 벨마우스부(84) 하측으로 루버절연물(80)의 전면 종측 길이방향으로 연장형성한 한쌍의 비이드(86)(88)에 의하여 유도되는 냉기가 손실되는 현상을 방지하기 위하여 냉동실루버(70)의 냉기공급덕트(90) 입구측단을 소정의 높이로 돌출되게 연장형성함이 바람직하다.On the other hand, the cold air induced by a pair of beads (86) 88 formed in the longitudinal direction of the front longitudinal side of the louver insulator (80) below the bell mouse portion (84) of the cold air blowing fan (50) for the refrigerating compartment. In order to prevent the loss phenomenon, it is preferable to extend the inlet side end of the cold air supply duct 90 of the freezing chamber 70 to a predetermined height.
이하에서는 상술한 바와 같이 이루어진 실시예에 따라 본 고안의 작용 및 효과를 설명하고자 한다.Hereinafter will be described the operation and effect of the present invention according to the embodiment made as described above.
먼저, 냉동실용 냉기송풍팬(40)이 구동중단되고 냉장실용 냉기송풍팬(50)만이 구동되어 증발기(60)에서 생성된 냉기가 냉장실용 냉기송풍팬(50)에 의하여 강제되면, 냉장실용 냉기송풍팬(50)에 의하여 강제되는 냉기의 흐름은 냉장실용 냉기송풍팬(50)의 벨마우스부(84) 하측으로 루버절연물(80)의 전면 종측 길이방향으로 연장형성한 한쌍의 비이드(86)(88)에 의하여 유도되어 냉동실루버(70) 표면을 따라서 냉기공급덕트(90)로 유입되어진다.First, if the cold air cooling fan 40 for the freezer compartment is stopped and only the cold air cooling fan 50 for the refrigerating compartment is driven so that the cold air generated in the evaporator 60 is forced by the cold air cooling fan 50 for the cold compartment, the cold air for the cold compartment The flow of cold air forced by the blowing fan 50 is a pair of beads 86 extending in the longitudinal longitudinal direction of the front side of the louver insulator 80 below the bell mouth portion 84 of the cold air cooling fan 50 for the refrigerating chamber. Guided by the 88 is introduced into the cold air supply duct 90 along the surface of the freezing chamber (70).
이때에 냉장실용 냉기송풍팬(50)의 벨마우스부(84) 하측으로 루버절연물(80)의 전면 종측 길이방향으로 연장형성한 한쌍의 비이드(86)(88)에 의하여 유도되는 냉기의 일부는 양측 비이드(86)(88) 사이로 루버절연물(80) 전면에 형성된 다수의 돌출턱(89)에 의하여 저항을 받아 냉동실용 냉기송풍팬(40) 측의 비이드(86)에 형성된 냉기통공(87)을 통하여 냉동실루버(70)의 표면으로 전달되어진다.At this time, a part of the cold air guided by a pair of beads (86) 88 formed in the longitudinal direction of the front longitudinal side of the louver insulator (80) below the bell mouse portion (84) of the cold air blowing fan (50) for the refrigerating compartment. The cold air hole formed in the bead 86 on the cold air blower fan 40 side for the freezer compartment is received by the plurality of protruding jaws 89 formed on the front surface of the louver insulator 80 between the two beads 86 and 88. It is transmitted to the surface of the freezing chamber 70 through the 87.
따라서 냉동실용 냉기송풍팬(40)이 구동중단되고 냉장실용 냉기송풍팬(50)만이 구동될 경우에 냉기의 역류현상으로 인하여 냉동실(10)내의 온도상승된 냉기가 냉동실루버(70)의 표면에 접하게 되더라도 냉동실루버(70)를 경계로 한 양측의 온도편차가 감소되어 냉동실루버(70)의 표면에는 이슬맺힘현상 및 착상현상이 발생되지 않으며, 냉장실(20)로 공급되는 냉기의 흐름이 저항을 받지 않아 냉장실(20)로의 냉기공급이 원활히 이루어져 냉장실(20)내에 수납한 저장물의 냉각효율이 향상되어진다.Therefore, when the freezing air cooling fan 40 for the freezer compartment is stopped and only the cold air cooling fan 50 for the refrigerating compartment is driven, the cold air having risen in temperature in the freezing compartment 10 due to the backflow of the cold air is applied to the surface of the freezing chamber 70. Even if contacted, the temperature deviation of both sides of the freezing chamber 70 is reduced, so that dew condensation and frost phenomenon do not occur on the surface of the freezing chamber 70, and the flow of cold air supplied to the refrigerating chamber 20 resists the resistance. Since the cold air supply to the refrigerating chamber 20 is smoothly received, the cooling efficiency of the storage stored in the refrigerating chamber 20 is improved.
이상에서 살펴본 바와 같이 본 고안은 냉장실용 냉기송풍팬의 벨마우스부 하측으로 루버절연물의 전면에 종측 길이방향으로 연장형성한 한쌍의 비이드와, 냉동실용 냉기송풍팬 측의 비이드에 일정간격을 두고 다수 형성한 냉기통공과, 양측 비이드 사이로 루버절연물 전면에 형성한 다수의 돌출턱을 포함하는 구성으로 이루어지므로써, 냉장실로 공급되는 냉기의 흐름이 저항을 받지 않아 냉장실로의 냉기공급이 원활히 이루어져 냉장실 내에 수납된 저장물의 냉각효율이 향상됨은 물론 냉동실용 냉기송풍팬이 구동 중단되고 냉장실용 냉기송풍팬만이 구동될 경우에도 냉동실루버를 경계로 한 양측의 온도편차로 인하여 냉동실루버의 표면에 이슬맺힘현상 및 착상현상이 발생됨이 방지되는 효과를 갖는 매우 유용한 고안인 것이다.As described above, the present invention provides a pair of beads extending longitudinally in the longitudinal direction on the front side of the louver insulator under the bellows portion of the cold air blowing fan for the refrigerating compartment, and the bead on the cold air blowing fan side for the freezing compartment. It consists of a plurality of cold air holes and a plurality of protruding jaw formed on the front of the louver insulator between the two bead, so that the flow of cold air to the refrigerating chamber is not resisted, so the supply of cold air to the refrigerating chamber is smooth. As a result, the cooling efficiency of the storage stored in the refrigerating compartment is improved, and even when the cold air cooling fan for the freezing compartment is stopped and only the cold air cooling fan for the refrigerating compartment is driven, It is a very useful design having the effect of preventing dew condensation and frost phenomenon.
