It is a perspective view showing.

도 1에 도시하고 있는 바와 같이 본 발명에 의한 냉장고 냉동실(1)은 도어(10), 냉기 덕트(20), 상ㅇ하 박스(30,31), 그리고 이슬 맺힘 방지부(40)를 포함 하여 구성된다.As shown in FIG. 1, the refrigerator freezer compartment 1 according to the present invention includes a door 10, a cold air duct 20, upper and lower boxes 30 and 31, and an anti-dew portion 40. It is composed.

상기 냉동실(1)은 후면 하단에 소정 길이로 경사를 갖는 경사면(12)이 형성된 몸체(11)와, 전면에 설치되는 도어(10)를 포함하여 이루어진다.The freezer compartment 1 includes a body 11 having an inclined surface 12 having an inclination with a predetermined length at a lower rear side thereof, and a door 10 installed at the front surface thereof.

상기 냉동실(1)의 내부에 마련되는 상ㅇ하 박스(30,31)는 상기 냉동실(1)에 음식물을 저장하기 위한 저장 공간이며, 상기 냉동실(1) 내측 상ㅇ하측 위치에 각각 구비된다.Upper and lower boxes 30 and 31 provided inside the freezing compartment 1 are storage spaces for storing food in the freezing compartment 1, and are provided at upper and lower positions inside the freezing compartment 1, respectively.

상기 냉기 덕트(20)는 상기 냉동실(1)의 후방에 위치하며, 상기 냉동실(1)에 냉기를 공급하도록 형성된 다수개의 냉기 유출공(21)을 포함한다.The cold air duct 20 is located at the rear of the freezing chamber 1 and includes a plurality of cold air outlet holes 21 formed to supply cold air to the freezing chamber 1.

그리고, 상기 냉기 덕트(20)의 전면부 하단 소정 위치에 이슬 맺힘 방지부(40)가 돌출되게 형성되며, 상기 이슬 맺힘 방지부(40)의 형상은 그 중앙이 상향 으로 벤딩된 형상으로 상기 냉동실(1)의 하측에서 상측으로 올라오는 외기의 흐름을 차단하여, 상존하는 냉기와의 착상을 방지 한다.In addition, the dew condensation preventing portion 40 is formed to protrude at a predetermined lower portion of the front portion of the cold air duct 20, and the dew condensation preventing portion 40 has a shape in which a center thereof is bent upward. The flow of outside air rising from the lower side to the upper side of (1) is cut off to prevent frost from existing cold air.

또한, 상기 이슬 맺힘 방지부(40)는 다수개로 형성 가능하다.In addition, the dew condensation preventing portion 40 may be formed in plural.

냉장고가 구동되면 상기 냉동실(1)의 내부로 상기 냉기 덕트(20)의 냉기 유출공(21)을 통해 냉기가 공급되어 상기 냉동실(1) 내부에 냉기가 상존하게 된다.When the refrigerator is driven, cold air is supplied to the inside of the freezing chamber 1 through the cold air outlet hole 21 of the cold air duct 20 so that cold air remains in the freezing chamber 1.

그리고, 상기 냉동실(1) 사용 중 도어(10)의 닫힘 시 유입되는 유입 공기(A)가 상기 도어(10)의 닫힘 압력에 의해 상기 하박스(31)의 측면과 상기 몸체(11)의 바닥부로 집중 유입된다.In addition, the inflow air A introduced when the door 10 is closed while the freezer compartment 1 is in use is closed by the closing pressure of the door 10 and the side of the lower box 31 and the bottom of the body 11. It is concentrated in wealth.

상기 냉동실(1)에 유입되는 유입 공기(A)는 상기 몸체(11) 후면의 경사부(12)를 따라 상기 냉동실(1)의 상측으로 이동하다가 상기 이슬 맺힘 방지부(40) 에 의해 그 흐름이 차단된다.The inflow air (A) flowing into the freezing compartment (1) moves along the inclined portion (12) on the rear side of the body (11) to the upper side of the freezing compartment (1) and flows by the dew condensation preventing portion (40). Is blocked.

따라서, 상기 유입 공기(A)는 상기 차가운 공기(B)와 만나 착상할 수 없게 된다.Therefore, the inlet air A cannot meet the cold air B and can not be implanted.

이하, 본 발명의 실시예에 따른 냉동실 이슬 맺힘 방지부의 작용을 설명한다.Hereinafter, the operation of the freezing chamber dew condensation prevention unit according to an embodiment of the present invention.

냉장고의 구동시, 상기 냉동실(1)에 구비되는 상기 냉기 덕트(20)의 상기 냉기 유출공(21)을 통해 상기 냉동실(1)의 내부 전체로 냉기가 공급된다.When the refrigerator is driven, cold air is supplied to the entire interior of the freezer compartment 1 through the cold air outlet 21 of the cold air duct 20 provided in the freezer compartment 1.

상기 냉동실(1)의 도어(10)를 열고 저장물을 인ㅇ출입한 후에 상기 도어(10)를 닫을 때, 상기 도어(10)의 닫힘 압력에 의해 외부의 유입 공기(A)가 상기 냉동실(1)의 내측 하부, 즉 상기 하박스(31)의 측면으로 유입된다.When the door 10 is closed after opening the door 10 of the freezer compartment 1 and drawing in and out of the storage, the inflow air A of the outside is caused by the closing pressure of the door 10 so that the freezer compartment Inside the lower portion of 1), that is, flows into the side of the lower box (31).

그리고, 하측으로 유입된 상기 유입 공기(A)는 상기 몸체(11)의 경사면(12)을 따라 상측으로 이동하게 되는데, 이때 상기 냉기 덕트(20) 전면에 형성된 상기 이슬 맺힘 방지부(40)에 의해 상기 유입 공기(B)의 흐름은 상기 냉기 덕트(20) 전면으로의 이동이 차단되며 따라서, 상기 차가운 공기(B)와 착상을 방지하고, 이슬 맺힘을 방지 할 수 있다.In addition, the inflow air (A) introduced to the lower side is moved upward along the inclined surface 12 of the body 11, wherein the dew condensation preventing portion 40 formed on the front surface of the cold air duct 20 As a result, the flow of the inlet air B is blocked from moving to the front surface of the cold air duct 20, thus preventing the cold air B from being implanted and preventing dew formation.

이상에서 설명한 바와 같이 상기와 같은 구성을 갖는 본 발명은 냉동실 덕트 전면부에 립 형상의 이슬 맺힘 방지부를 형성하여 외기와 내기의 온도차에 따른 착상을 방지하여 이슬 맺힘 현상을 방지할 수 있는 효과를 거둘 수 있다.As described above, the present invention having the configuration as described above has an effect of preventing dew condensation by forming a lip-shaped dew condensation preventing part on the front surface of the freezing chamber duct to prevent frosting due to the temperature difference between the outside and the bet. Can be.
