종래의 냉장고를 보면 도1에서 개시된 바와 같이, 본체(1)에는 그 하부에 마련된 냉동실(3)과, 그 상부에 마련된 냉장실(5)과, 상기 냉장실(5)의 상측에 별도로 구획되어 있는 제빙실(7)이 형성되어 있다. Referring to the conventional refrigerator, as shown in FIG. 1, the main body 1 includes a freezing compartment 3 provided at a lower portion thereof, a refrigerating chamber 5 provided at an upper portion thereof, and a second compartment separately disposed at an upper side of the refrigerating chamber 5. An ice chamber 7 is formed.

그리고, 상기 냉동실(3)과 상기 냉장실(5)의 후방에는 각각 냉동실용 하부증발기(10)와 냉장실용 상부증발기(13)가 마련되어져 있으며, 냉동실용 하부증발기(10)에는 제상작업시 열을 발생하는 제상히터(11)가 설치된다. In addition, a freezer compartment lower evaporator 10 and a freezer compartment upper evaporator 13 are provided at the rear of the freezer compartment 3 and the refrigerating compartment 5, respectively, and the lower evaporator 10 for the freezer compartment provides heat during defrosting. The defrost heater 11 which generate | occur | produces is installed.

한편, 상기 제빙실(7)에서 제빙작업이 이루어질 수 있도록 제빙실(7) 내부의 온도는 냉동실(3)의 냉기 온도와 거의 동일하게 조절되어야 하는데, 이를 위하여 상기 제빙실(7)과 냉동실(3) 사이에는 이들을 연통시키는 제1냉기덕트(16)와, 제2냉기덕트(19)가 마련된다.On the other hand, the temperature inside the ice-making chamber (7) should be adjusted to be almost the same as the cold air temperature of the freezing chamber (3) so that the ice-making operation in the ice-making chamber (7), for this purpose, the ice-making chamber (7) and the freezing chamber ( Between 3), the 1st cold air duct 16 and the 2nd cold air duct 19 which connect these are provided.

여기서, 제1냉기덕트(16)는 냉동실(3)의 냉기를 제빙실(7)로 안내하는 역할을 하고, 제2냉기덕트(19)는 제빙실(7) 내부의 공기를 냉동실(3)로 안내하는 역할을 함으로써, 냉동실(3)과 제빙실(7)사이에 공기가 순환되도록 한다.Here, the first cold air duct 16 serves to guide the cold air of the freezing chamber 3 to the ice making chamber 7, and the second cold air duct 19 directs the air inside the ice making chamber 7 to the freezing chamber 3. By acting as a guide, the air is circulated between the freezing chamber (3) and the ice making chamber (7).

여기서, 제빙실(7)의 냉기를 제빙실(7) 방향으로 신속하게 이동시킬 수 있도록, 제1냉기덕트(16)에는 송풍장치(21)가 마련되는데, 상기 송풍장치(21)는 그 내부에 원심팬 형상의 송풍팬(23)과, 송풍팬(23)이 수용되며 제1냉기덕트(16)와 연결되는 팬케이싱(25)과, 팬케이싱(25)의 전면에 마련된 흡입구(27)를 포함한다.Here, a blower 21 is provided in the first cold air duct 16 so that the cold air of the ice making chamber 7 can be quickly moved in the direction of the ice making chamber 7, and the blower 21 has an inside thereof. A blowing fan 23 having a centrifugal fan shape, a blowing fan 23, and a fan casing 25 connected to the first cold air duct 16, and a suction port 27 provided on the front surface of the fan casing 25. It includes.

일반적으로 하부증발기(10)에서 냉기가 발생하여 일정한 시간이 경과하면, 하부증발기(10)에는 서리가 발생하게 되므로, 제상히터(11)의 발열작용으로 인하여 그 서리를 제거하여야 한다.In general, when a certain time elapses due to the occurrence of cold air in the lower evaporator 10, since the frost occurs in the lower evaporator 10, the frost must be removed due to the exothermic action of the defrost heater 11.

이때, 도2에서 도시한 바와 같이, 제상히터(도1참조,11)의 발열작용으로 인하여 하부증발기(도1참조,10) 주위의 공기의 온도가 상승하게 되며, 따라서, 송풍장치(21)내부의 온도도 상승하게 되면, 팬케이싱(25) 내부에서는 냉기가 수증기가 포함된 공기(A)로 변하게 되고, 이에 팬케이싱(25)의 내벽에는 그러한 수증기의 응결로 인한 결로(結露)(D)가 형성되며, 이후, 결로(D)는 자중에 의하여 팬케이싱(25)의 하부에 누적된다.At this time, as shown in Figure 2, due to the exothermic action of the defrost heater (see Fig. 1, 11) the temperature of the air around the lower evaporator (see Fig. 1, 10) is raised, and thus, the blower 21 If the internal temperature also rises, cold air inside the pan casing 25 is changed to air A containing water vapor, and condensation due to condensation of such water vapor on the inner wall of the pan casing 25 (D) ) Is then formed, and condensation (D) accumulates on the lower portion of the pan casing 25 by its own weight.

그렇게 누적된 결로는 작은 웅덩이를 이루게 되고, 제상작용 및 냉동싸이클 과정을 거침에 따라서, 그 웅덩이의 수위(W)는 점점 높아져서 송풍팬(23)과 접촉하게 된다.The accumulated condensation forms a small puddle, and as the defrosting and freezing cycle process is performed, the water level W of the puddle becomes higher and comes into contact with the blowing fan 23.

이와 같은 상태가 되면 송풍팬(23)의 작동이 원활하지 못하여 냉기 전달 효율이 급감하거나, 아예 누적된 물이 송풍팬(23)과 접하는 상태에서 결빙되면 송풍팬(23)의 회전이 불가능해진다는 문제점이 있었다. In this state, the operation of the blower fan 23 is not smooth, and thus the cooling air transmission efficiency decreases rapidly, or when the accumulated water is frozen in contact with the blower fan 23, the rotation of the blower fan 23 becomes impossible. There was a problem.

본 발명은 이러한 문제점을 해결하기 위한 것으로, 냉기덕트와 연결되는 송풍장치내에서 응결되는 결로가 그 외부로 배출되게 함으로서, 결로의 누적으로 인한 송풍장치 작동고장을 방지하고, 냉기의 공급이 원활하게 이루어 질 수 있도록 하는데 그 목적이 있다.

이하에서는 첨부된 도면을 참조하여 본 발명의 동작에 대하여 알아보기로 하겠다. Hereinafter, an operation of the present invention will be described with reference to the accompanying drawings.

도3에서 도시한 바와 같이, 상기 냉장실(103) 내부의 공기는 상기 하부증발기(110)와 열교환 하여 온도가 하강하여 냉기가 되고, 그러한 냉기는 상기 송풍팬(123)의 흡입 및 토출작용에 의하여 상기 제1냉기덕트(116)를 타고 화살표방향으로 이동한다. As shown in FIG. 3, the air inside the refrigerating chamber 103 exchanges heat with the lower evaporator 110 and the temperature decreases to form cold air, and such cold air is caused by the suction and discharge of the blower fan 123. The first cold air duct 116 is moved in the direction of the arrow.

상기 제1냉기덕트(116)의 안내를 받아 상기 제1냉기토출구(140)를 통과하여 상기 제빙실(107)로 이동한 냉기는 상기 제빙실(107)에 설치된 제빙기(미도시)에 담긴 물을 제빙하는 역할을 한다.The cold air moved to the ice making chamber 107 by passing through the first cold air outlet 140 and guided by the first cold air duct 116 is water contained in an ice maker (not shown) installed in the ice making chamber 107. Serves to ice.

한편, 이후 제빙실(107)에 있던 공기는 상기 냉기유입구(145)를 통과하여 상기 제1냉기덕트(119)의 안내를 받아서 상기 제2냉기토출구(150) 밖으로 토출되어 다시 냉동실(103) 내부의 냉기들과 혼합된 후, 다시 상기 하부증발기(110)와 열교환한뒤에 다시 상술한 과정을 반복함으로써 상기 냉장실(103)과 상기 제빙기(107)를 순환한다.On the other hand, the air in the ice-making chamber 107 is passed through the cold air inlet 145, guided by the first cold air duct 119 is discharged out of the second cold air outlet 150 and again inside the freezing chamber 103 After mixing with the cold air of the circulating the refrigerating chamber 103 and the ice maker 107 by repeating the above-described process again after heat exchange with the lower evaporator 110 again.

이러한 과정이 상당시간 지속되면, 상기 하부하부증발기(110)에는 서리가 형 성되어서 원활한 열교환작용을 방해하므로, 이러한 서리를 제거하기 위한 제상작업이 실시되어야 한다.If this process continues for a considerable time, since the lower lower evaporator 110 is formed frost to prevent a smooth heat exchange action, defrosting to remove such frost should be carried out.

이를 위하여, 상기 하부증발기(110)에 마련된 제상히터(111)가 발열하게 되면 상기 하부증발기(110)에 형성된 서리를 융해시킨 다음 증발시키는데, 이러한 과정중에 상기 냉장실(103) 후방의 공기의 온도가 올라가게 되고, 이러한 공기를 흡입하는 상기 송풍장치(121) 내부에도 습기를 포함한 공기가 충만하게 된다.To this end, when the defrost heater 111 provided in the lower evaporator 110 generates heat, the frost formed in the lower evaporator 110 is melted and then evaporated. During this process, the temperature of the air behind the refrigerating chamber 103 is increased. As it rises, the air including moisture is also filled in the blower 121 that sucks the air.

도5에서 도시한 바와 같이, 그러한 습한 공기(A)에 분산되어 있는 물분자가 상기 팬케이싱(125) 내벽에 닿게 되면 그 부분에 결로(D)가 맺히게 되는 현상이 일어나고, 그 결로(D)가 일정한 크기 이상이 되면, 자중에 의하여 상기 팬케이싱(125) 내벽을 타고 아래로 흐르게 된다.As shown in FIG. 5, when water molecules dispersed in such humid air A come into contact with the inner wall of the pan casing 125, condensation D forms in a portion thereof, and condensation D occurs. When is greater than or equal to a certain size, it flows down the inner wall of the pan casing 125 by its own weight.

그러한 결로(D)가 상기 팬케이싱(125)의 하부에 이르게 되면, 상기 결로배출공(165)을 통과하고, 상기 안내부(170)의 안내를 받아서 상기 팬케이싱(125)의 하부로 낙하한다.When the condensation (D) reaches the lower portion of the pan casing 125, it passes through the condensation discharge hole 165, and is guided by the guide portion 170 to fall to the lower portion of the pan casing 125. .

이렇게 낙하한 결로(D)은 상기 하부증발기(도3참고, 110)의 상면이나 그 주위에 위치한 뒤에, 상기 히터(도3참고, 111)의 발열 및 증발작용에 의하여 증발되어 없어지게 된다. The condensation D thus dropped is located on or around the upper surface of the lower evaporator (refer to FIG. 3 and 110), and then evaporates and disappears due to the heat generation and evaporation of the heater (refer to FIG. 3 and 111).

상기와 같은 구성을 갖는 본 발명에 의하여, 냉기를 유동시키는 송풍장치 내부에 결로현상으로 인하여 발생한 물방울이 누적되지 아니하고 그 외부로 원활하게 배출됨으로써 송풍장치의 작동시 결로로 인하여 방해받는 일이 사라지게 된다.According to the present invention having the configuration as described above, the water droplets generated due to the condensation phenomenon inside the blower that flows the cold air is not accumulated, and smoothly discharged to the outside, thereby preventing the disturbance caused by the condensation during the operation of the blower. .

따라서, 냉동실에서 제빙실로의 냉기의 이동이 원활하게 이루어 질 수 있는 효과가 있는 것이다.Therefore, there is an effect that the movement of cold air from the freezing chamber to the ice making chamber can be made smoothly.
