본 고안은 냉장고에 관한 것으로, 특히 증발기에서 생성된 냉기를 고내로 송풍시키기 위한 송풍팬 및 이 부근의 공기유로의 형상을 개선하여 증발기의 효율을 향상시키고 팬소음을 저감시킨 냉장고의 송풍장치에 관한 것이다.The present invention relates to a refrigerator, and in particular to a blower fan for blowing cold air generated in the evaporator and an air flower in the vicinity to improve the efficiency of the evaporator to improve the efficiency of the evaporator and to reduce the fan noise will be.
종래의 냉장고(1)는, 제1도에 도시한 바와 같이, 서로 구획되며 서로 다른 온도로 냉각되는 냉동실(2)과 냉장실(3)을 포함한다. 냉동실(2)의 후벽에는 증발기(4)와 송풍팬(5)이 설치된다. 송풍팬(5)은 증발기(4)의 상측에 설치되며, 그 전방에는 냉기토출구(6a)가 형성된 안내판(6)이 설치된다. 이 송풍팬(5)은 다수의 소형 날개(5a)가 축(5b)에 설치되고 축(5b)에는 구동모타(5c)가 결합된 프로펠라팬이다. 또한 냉동실(2)과 냉장실(3)을 구획하는 중간벽(7)에는 냉동실복귀유로(7a)와 냉장실복귀유로(7b)가 형성되어 각 실의 공기가 증발기(4)로 유입되는 것을 안내한다. 한편 송풍팬(5)을 거친 냉기의 일부는 냉기토출구(6a)를 통해 냉동실(2)로 공급되고 안내판(6)에 부딪친 나머지 냉기는 하방으로 안내되어 냉장실(3)로 공급된다.The conventional refrigerator 1, as shown in FIG. 1, includes a freezer compartment 2 and a refrigerating compartment 3, which are partitioned from each other and cooled to different temperatures. An evaporator 4 and a blowing fan 5 are installed on the rear wall of the freezing chamber 2. The blowing fan 5 is installed above the evaporator 4, and a guide plate 6 having a cold air discharge port 6a is provided at the front thereof. This blowing fan 5 is a propeller fan in which a plurality of small vanes 5a are installed on the shaft 5b, and the driving motor 5c is coupled to the shaft 5b. In addition, a freezer compartment return passage 7a and a refrigerating compartment return passage 7b are formed in the intermediate wall 7 partitioning the freezer compartment 2 and the refrigerating compartment 3 to guide the inflow of air from each chamber into the evaporator 4. . On the other hand, a part of the cold air passing through the blowing fan 5 is supplied to the freezing chamber 2 through the cold air discharge port 6a, and the remaining cold air that is hit by the guide plate 6 is guided downward and is supplied to the refrigerating chamber 3.
한편, 제2도에 도시한 바와 같이, 송풍팬(5)은 증발기(4)의 중앙부 상측에 위치되고 날개(5a)의 외경이 증발기(4)의 폭보다 매우 작게 설치되므로 복귀유로(7a)(7b)를 통해 증발기(4)로 안내된 공기의 대부분은 증발기의 중앙부분만을 통과하게 되어 있어 증발기의 양측(제2도의 빗금친 부분)에는 많은양의 성에가 착상되어 증발기의 효율이 떨어지는 문제점이 있었다. 이에 따라 요구되는 열교환 효과를 얻기 위해서는 증발기의 크기를 확대하여야 하는 문제점이 있었다. 또한 송풍팬을 통과한 냉기의 일부는 다수의 소형 냉기토출구를 통과하고 일부는 매우 강하게 안내판에 부딪치게 되므로 팬소음이 발생하는 문제점이 있었다. 또한 팬의 크기가 작고 이에 따라 팬이 설치된 부위의 공간(벨 마우스)도 좁아 토출되는 냉기의 양이 적을 뿐만 아니라 요구되는 냉기의 토출을 위해서는 팬의 회전속도를 증대시켜야 하는 문제가 있었고, 이에 따라 소비전력이 상승하는 문제점이 있었다.On the other hand, as shown in FIG. 2, the blowing fan 5 is located above the central part of the evaporator 4, and the outer flow path of the wing 5a is installed so that the width of the evaporator 4 is much smaller than the return flow path 7a. Most of the air guided to the evaporator (4) through (7b) passes through only the central part of the evaporator, so that a large amount of frost is formed on both sides of the evaporator (hatched portion of FIG. 2), and the efficiency of the evaporator is lowered. There was this. Accordingly, there is a problem in that the size of the evaporator should be enlarged in order to obtain the required heat exchange effect. In addition, some of the cold air passing through the blower fan passes through a number of small cold air outlet, and some hit the guide plate very strongly, there was a problem that the fan noise occurs. In addition, the size of the fan is small and accordingly the space (bell mouse) in the area where the fan is installed is not only a small amount of cold air discharged, but also had to increase the rotational speed of the fan to discharge the required cold air, accordingly There was a problem that power consumption is increased.
따라서 본 고안은 이러한 문제점을 해결하기 위한 것으로 본 고안의 목적은, 증발기의 효율을 증대시키고 동시에 팬소음을 저감시키는 냉장고의 냉기송풍장치를 제공하는 것이다.Therefore, the present invention is to solve this problem, the object of the present invention is to provide a cold air blower of the refrigerator to increase the efficiency of the evaporator and at the same time reduce the fan noise.

제3도에 도시한 바와 같이, 본 고안이 적용되는 냉장고(10)는 냉동실(11)과 냉장실(12)을 포함하여 이들은 중간벽(13)에 의해 구획된다. 냉동실(11)의 후벽에는 증발기(20)가 입설되고, 증발기(20)의 전방에는 증발기덮개(21)가 설치된다. 증발기덮개(21)의 전방에는 증발기덮개(21)와의 사이에 냉기유로(31)를 형성하도록 전면판(30)이 설치된다. 증발기(20) 상측의 증발기덮개(21) 상단과 전면판(30) 사이에는 송풍팬(40)이 설치된다. 송풍팬(40)의 설치를 위해 전면판(30)에는 돔형으로 형성된 토출부(32)가 마련되고, 이 토출부(30)에 다수의 냉기토출구(33)가 형성된다. 또한 냉장실(12)의 후벽에는 냉기유로(31)와 연통되어 냉장실덕트(50)가 설치되고, 이 냉장실덕트(50)에는 냉기토출구(51)가 상하로 배열된다. 한편, 냉동실(11)과 냉장실(12)을 구획하는 중간벽(13)에는 각 실의 공기가 증발기(20)로 유입되는 것을 안내하기 위해 냉동실복귀유로(13a)와 냉장실복귀유로(13b)가 마련된다.As shown in FIG. 3, the refrigerator 10 to which the present invention is applied includes a freezing compartment 11 and a refrigerating compartment 12, which are divided by an intermediate wall 13. An evaporator 20 is placed on the rear wall of the freezer compartment 11, and an evaporator cover 21 is installed in front of the evaporator 20. The front plate 30 is installed in front of the evaporator cover 21 to form a cold air flow passage 31 between the evaporator cover 21. A blowing fan 40 is installed between the top of the evaporator cover 21 and the front plate 30 above the evaporator 20. In order to install the blowing fan 40, the front plate 30 is provided with a discharge portion 32 formed in a dome shape, and a plurality of cold air discharge ports 33 are formed in the discharge portion 30. In addition, the rear wall of the refrigerating chamber 12 communicates with the cold air passage 31, and the refrigerating chamber duct 50 is provided. The refrigerating chamber duct 50 has cold air outlets 51 arranged up and down. On the other hand, in the intermediate wall 13 partitioning the freezer compartment 11 and the refrigerating compartment 12, a freezer compartment return passage 13a and a refrigerating compartment return passage 13b are provided to guide the inflow of air from each chamber into the evaporator 20. Prepared.
제3도와 제4도에 도시한 바와 같이, 송풍팬(40)은 증발기(20)의 폭방향으로 증발기(20)와 나란하게 배치된 축(41), 축(41)의 외주면에 마련되며 증발기(20)의 폭과 비슷한 길이를 가진 다수의 날개(42), 축(41)의 일단에 설치되어 축(41)을 회전시키는 모타(43)를 포함한다, 전술한 전면판(30)의 냉기토출구(33)도 날개(42)의 길이와 상응하도록 배치된다. 이때 날개(42)는 냉기의 회전방향과 상응하도록 만곡되어 형성된다(제3도 참조). 이와 같이 날개(42)의 길이가 증발기(20)의 폭과 비슷하므로 증발기(20)를 통과하는 공기는 증발기(20)의 중앙부분은 물론 양측으로도 통과하게 된다.As shown in FIG. 3 and FIG. 4, the blowing fan 40 is provided on the outer circumferential surface of the shaft 41 and the shaft 41 which are arranged in parallel with the evaporator 20 in the width direction of the evaporator 20, and the evaporator. A plurality of wings 42 having a length similar to the width of 20, and a motor 43 installed at one end of the shaft 41 to rotate the shaft 41. The cold air of the front plate 30 described above The discharge port 33 is also arranged to correspond to the length of the blade 42. At this time, the blade 42 is formed to be curved to correspond to the rotational direction of the cold air (see Fig. 3). As such, since the length of the blade 42 is similar to the width of the evaporator 20, the air passing through the evaporator 20 passes through both sides as well as the central portion of the evaporator 20.
한편, 제5도에 도시한 바와 같이, 증발기덮개(21)의 상단에는 전술한 토출부(32)와 함께 송풍팬(40)을 수용하도록 만곡 형성된 안내부(21a)가 마련되는데, 이 안내부(21a)의 상측에서는 증발기(20)를 통과한 냉기가 송풍팬(40)으로 유입되는 것을 안내하고, 하측에서는 송풍팬(40)을 통과한 냉기가 냉기유로(31)를 통해 하방으로 배출되는 것을 안내한다.On the other hand, as shown in Figure 5, the upper end of the evaporator cover 21 is provided with a guide portion 21a curved to accommodate the blowing fan 40 together with the above-described discharge portion 32, this guide portion The upper side of the (21a) guides the cold air passing through the evaporator 20 to the blowing fan 40, the lower side is discharged downward through the cold air flow path (31) through the cooling fan (40). To guide.
이상과 같이 구성된 본 고안에 따른 냉장고의 냉기송풍장치의 작용을 설명하면 다음과 같다.Referring to the operation of the cold air blower of the refrigerator according to the present invention configured as described above are as follows.
고내의 온도가 식품보관을 위한 적절한 온도로 미리 정해진 설정온도 이상으로 상승되면 이를 감지한 제어부(도시안됨)의 제어에 의해 냉장고가 작동한다. 따라서 증발기(20)에서는 냉매가 증발하면서 주위의 열을 흡수하게 되고 송풍팬(40)은 회전하게 된다. 송풍팬(40)이 회전함에 따라, 냉동실(11)의 공기는 냉장실복귀유로(13a)를 통해서 냉장실(12)의 공기는 냉장실복귀유로(13b)를 통해서 안내되어 증발기(20)를 통과하여 흐르게 되고 증발기(20)의 내부를 흐르는 냉매와의 열교환을 수행한다. 이에 따라 증발기(20)를 통과하면서 차가워진 냉기는 증발기덮개(21)의 상단에 마련된 안내부(21a)에 의해 안내되어 일부는 토출부(32)에 형성된 냉기토출구(33)를 통해 냉동실(11)로 공급되고 나머지는 하방으로 배출되어 냉기유로(31)와 냉장실덕트(50)를 통해 냉장실(12)로 공급된다.When the temperature in the refrigerator rises above a predetermined set temperature to an appropriate temperature for food storage, the refrigerator is operated by the control of a control unit (not shown) which detects the temperature. Therefore, the evaporator 20 absorbs the surrounding heat while the refrigerant evaporates, and the blowing fan 40 rotates. As the blowing fan 40 rotates, the air in the freezer compartment 11 passes through the refrigerating chamber return passage 13a and the air of the refrigerating compartment 12 is guided through the refrigerating chamber return passage 13b to flow through the evaporator 20. And heat exchange with the refrigerant flowing inside the evaporator 20. Accordingly, the cold air cooled while passing through the evaporator 20 is guided by the guide part 21a provided at the upper end of the evaporator cover 21, and a part of the freezing chamber 11 is provided through the cold air discharge port 33 formed in the discharge part 32. ) Is supplied to the refrigerating chamber 12 through the cold air flow path 31 and the refrigerating chamber duct 50.
이때, 송풍팬(40)의 날개(42)가 증발기(20)의 폭과 비슷한 길이를 가지므로 증발기(20)를 통과하는 공기는, 제4도에 도시한 바와 같이, 증발기(20)의 중앙 부분만이 아니고 양측으로도 통과하게 되어 증발기의 열교환효율이 매우 향상된다. 즉, 증발기(20)를 통과하는 공기는 증발기(20)를 전체적으로 지나게 되므로 증발기의 활용도가 높아지며, 특정부위에 집중적으로 성에가 착상되는 문제점이 발생하지 않게된다. 또한 길이가 긴 날개를 가진 송풍팬을 사용하므로 송풍량이 증대되고, 이에 따라 팬을 저속으로 회전시켜도 되므로 송풍팬을 구동시키기 위한 소비전력의 절감 및 팬소음의 발생을 방지할 수 있다.At this time, since the blade 42 of the blowing fan 40 has a length similar to the width of the evaporator 20, the air passing through the evaporator 20, as shown in Figure 4, the center of the evaporator 20 The heat exchange efficiency of the evaporator is greatly improved by passing not only the portion but also on both sides. That is, since the air passing through the evaporator 20 passes through the evaporator 20 as a whole, the utilization of the evaporator is increased, and the problem that frost is implanted intensively in a specific part does not occur. In addition, since the blower fan having a long blade is used, the blowing amount is increased, and thus, the fan may be rotated at a low speed, thereby reducing power consumption and fan noise for driving the blower fan.
이상에서 상세히 설명한 바와 같이, 본 고안에 따른 냉장고의 냉기송풍장치에 의하면, 증발기의 폭과 대략 비슷한 길이의 날개를 가진 송풍팬을 사용하므로 증발기를 전체적으로 활용할 수 있어 증발기의 효율이 향상되고, 송풍량이 증대되므로 팬소음이 저감되고 팬의 구동을 위한 소비전력이 저감되는 효과가 있다.As described above in detail, according to the cold air blower of the refrigerator according to the present invention, since the blower fan having a length approximately the same as the width of the evaporator is used, the evaporator can be used as a whole to improve the efficiency of the evaporator, Since the fan noise is increased, the power consumption for driving the fan is reduced.
