Description
본 고안은 냉장고용 냉기 순환장치에 관한 것으로, 더욱 상세하게는 저장실 내부의 냉기를 순환시키는 순환팬과 모터의 설치구조가 개선된 냉장고용 냉기 순환장치에 관한 것이다.The present invention relates to a cold air circulation device for a refrigerator, and more particularly, to a cold air circulation device for a refrigerator having an improved installation structure of a circulation fan and a motor for circulating cold air inside a storage compartment.

이러한 냉장고는 도 1에 도시된 바와 같이, 본체(1)의 내부에 저장실(2)이 형성되고, 이 저장실(2)의 전면 개구부에는 저장실(2)을 개폐하는 도어(3)가 설치되어 있다. 또한, 저장실(2) 내부의 후면 벽체에는 냉기를 생성하는 증발기(4)가 설치되고, 증발기(4)의 상부에는 증발기(4)를 거치면서 열교환이 된 냉기를 저장실(2)의 내부로 강제 순환시키는 냉기 순환장치(5)가 마련되어 있다. 또한, 저장실(2)의 후면 벽체에는 냉기의 흐름을 안내하는 냉기 안내유로(6)가 마련되고, 이 냉기 안내유로(6)에는 냉기흡입구(8) 및 냉기토출구(9)가 형성되어 있다. 이때, 증발기(4) 및 냉기 순환장치(5)는 냉기 안내유로(6)를 형성하는 저장실 내측판(7)의 내부에 설치되어 있다.In the refrigerator, as illustrated in FIG. 1, a storage compartment 2 is formed inside the main body 1, and a door 3 that opens and closes the storage compartment 2 is provided in the front opening of the storage compartment 2. . In addition, an evaporator 4 for generating cold air is provided on the rear wall inside the storage compartment 2, and the cold air that has undergone heat exchange while passing through the evaporator 4 is forced into the storage compartment 2 at the upper part of the evaporator 4. The cold air circulation device 5 which circulates is provided. In addition, a cold air guide passage 6 for guiding the flow of cold air is provided in the rear wall of the storage chamber 2, and a cold air suction opening 8 and a cold air discharge outlet 9 are formed in the cold air guide passage 6. At this time, the evaporator 4 and the cold air circulation system 5 are provided inside the storage chamber inner plate 7 forming the cold air guide passage 6.
냉기 순환장치(5)는 회전력을 발생시키는 모터(5b)와, 이 모터(5b)의 회전축에 결합된 순환팬(5a)으로 구성되는데, 모터(5b)는 증발기(4)의 상부에 설치되고, 순환팬(5a)은 모터(5b)의 전방으로 돌출된 회전축에 결합되어 있다.The cold air circulation device 5 is composed of a motor 5b for generating a rotational force and a circulation fan 5a coupled to a rotation shaft of the motor 5b, the motor 5b being installed on the top of the evaporator 4 , The circulation fan 5a is coupled to the rotating shaft protruding forward of the motor 5b.
이러한 종래 냉장고는 모터(5b)의 구동에 의해 순환팬(5a)이 회전되면, 냉기흡입구(8)로 흡입된 공기가 증발기(4)를 거치면서 냉각된 후, 냉기 안내유로(6)를 따라 안내되어서 냉기토출구(9)로 토출된다.In the conventional refrigerator, when the circulation fan 5a is rotated by the driving of the motor 5b, the air sucked into the cold air intake port 8 is cooled while passing through the evaporator 4, and then along the cold air guide passage 6. It is guided and discharged to the cold air discharge port 9.
그러나, 이와 같이 구성된 종래 냉장고는 냉기 순환장치(5)를 구성하는 모터(5b)가 증발기(4)의 상부에 설치되고 순환팬(5a)이 모터(5b)의 전방(냉기흐름의 하류측)에 위치됨에 따라, 순환되는 냉기가 모터(5b)에 간섭이 되어 냉기의 흐름이 원활하지 못한 문제가 있었다. 또한, 증발기(4)의 상부공간(A)은 냉기의 흐름방향이 급격하게 바뀌는 굴곡유로로 구성되어 있고, 냉기를 송풍하는 순환팬(5a)은 상부공간(A)의 전방 쪽에 치우친 상태로 하나만 설치되어 있기 때문에, 냉기가 굴곡된 유로를 흐르는 동안 유동손실이 커져서 냉기의 송풍능력이 떨어지는 문제가 있었다.However, in the conventional refrigerator configured as described above, the motor 5b constituting the cold air circulation device 5 is installed on the upper part of the evaporator 4, and the circulation fan 5a is located in front of the motor 5b (downstream of the cold flow). As it is located in, there is a problem that the cold air circulated interferes with the motor (5b), the flow of cold air is not smooth. In addition, the upper space (A) of the evaporator (4) is composed of a bent flow path that changes the flow direction of cold air rapidly, only one circulation fan (5a) for blowing the cold air in a state inclined to the front side of the upper space (A) Since it was installed, there was a problem that the flow loss of the cold air was reduced due to the large flow loss while the cold air flows through the curved flow path.
본 고안은 이와 같은 문제점을 해결하기 위한 것으로, 본 고안의 목적은 순환팬과 모터의 설치구조를 개선하여 냉기 흐름을 원활하게 하는 동시에 냉기의 송풍능력을 향상시키는 냉장고용 냉기 순환장치를 제공하는 것이다.The present invention is to solve the above problems, an object of the present invention is to provide a cold air circulation device for the refrigerator to improve the air flow capacity of the cold air at the same time to improve the installation structure of the circulation fan and the motor smoothly. .

이하에서는 본 고안에 따른 바람직한 실시 예를 첨부 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment according to the present invention will be described in detail.
본 고안이 적용되는 냉장고는 도 2에 도시된 바와 같이, 본체(10)의 내부에 음식물이 저장되는 저장실(11)이 형성되고, 이 저장실(11)은 내부 공간을 구획하는 중간벽(12)에 의해 상부 냉동실(11a)과 하부 냉장실(11b)로 구획된다. 그리고 냉동실(11a)과 냉장실(11b)의 전면에는 이들을 개폐하는 도어(13)가 설치된다.In the refrigerator to which the present invention is applied, as shown in FIG. 2, a storage compartment 11 in which food is stored is formed in the main body 10, and the storage compartment 11 has an intermediate wall 12 partitioning an internal space. By the upper freezer compartment 11a and the lower refrigerating chamber 11b. And the door 13 which opens and closes these is provided in the front surface of the freezer compartment 11a and the refrigerating chamber 11b.
또한, 냉동실(11a)과 냉장실(11b)에는 저장물의 적재가 용이하도록 복층으로 구성된 선반(15)이 설치되고, 도어(13)의 내측면에는 크기가 작은 식품과 음료수 등을 꽂아 보관할 수 있도록 다단으로 구성된 도어선반(미도시)이 마련된다.In addition, the freezer compartment (11a) and the refrigerating chamber (11b) is provided with a shelf 15 consisting of a multi-layer to facilitate the storage of the storage, the door 13 is a multi-stage to store small foods and drinks, etc. A door shelf (not shown) is provided.
또한, 냉동실(11a)과 냉장실(11b)의 후면 벽체에는 냉기를 생성하는 증발기(16)가 각각 설치되며, 증발기(16)의 상측에는 저장실(11)의 냉기를 강제 순환시키는 냉기 순환장치(30)가 설치된다.In addition, an evaporator 16 for generating cold air is provided on the rear walls of the freezing chamber 11a and the refrigerating chamber 11b, and a cold air circulation system 30 forcibly circulating cold air in the storage chamber 11 above the evaporator 16. ) Is installed.
또한, 저장실(11) 내측 후면에는 순환되는 냉기의 흐름을 안내하는 냉기 안내유로(18)가 형성되는데, 이 냉기 안내유로(18)는 저장실(11)의 내측후면에 설치되는 내측판(19)과, 내측판(19)과 소정간격 이격된 후방 내측에 설치되는 냉기안내판(20)에 의해 이루어진다. 이때, 내측판(19)과 냉기안내판(20) 사이의 공간이 냉기의 토출을 안내하는 안내유로(18)가 되고, 냉기안내판(20)의 이면공간은 증발기(16)가 설치되는 냉각실(17)을 이룬다. 또한, 내측판(19)에는 저장실(11) 내부로 냉기가 토출되는 다수의 냉기토출구(21) 및 저장실(11)의 냉기가 다시 냉각실(17) 쪽으로 유입되는 냉기흡입구(22)가 형성된다. 그리고 냉기를 순환시키는 냉기 순환장치(30)는 냉기 안내유로(18) 및 냉각실(17)의 상부(증발기의 상부)에 설치된다.In addition, a cold air guide passage 18 is formed on the inner rear side of the storage compartment 11 to guide the flow of cold air circulated, and the cold air guide passage 18 is an inner side plate 19 installed on the inner rear surface of the storage compartment 11. And, the inner plate 19 is made by a cold air guide plate 20 which is installed in the rear inner spaced by a predetermined interval. At this time, the space between the inner plate 19 and the cold air guide plate 20 is a guide flow path 18 for guiding the discharge of cold air, and the back space of the cold air guide plate 20 is a cooling chamber in which the evaporator 16 is installed ( 17). In addition, the inner plate 19 is provided with a plurality of cold air discharge ports 21 through which cold air is discharged into the storage chamber 11 and a cold air suction port 22 through which cold air from the storage chamber 11 flows back into the cooling chamber 17. . And the cold air circulation apparatus 30 which circulates cold air is provided in the cold air guide flow path 18 and the upper part (upper part of the evaporator) of the cooling chamber 17. As shown in FIG.
한편, 냉기 순환장치(30)는 도 3에 도시된 바와 같이, 회전력을 발생시키는 모터(31)가 구비되고, 이 모터(31)의 회전축(32a,32b)에는 냉기를 송풍하는 두 개의 순환팬(33,34)이 설치된다. 이때 모터(31)의 회전축은 양측으로 연장되고, 양측으로 연장된 회전축(32a,32b)에는 제 1순환팬(33)과 제 2순환팬(34)이 각각 결합된다.Meanwhile, as illustrated in FIG. 3, the cold air circulation device 30 includes a motor 31 that generates rotational force, and two circulation fans that blow cold air to the rotation shafts 32a and 32b of the motor 31. (33,34) are installed. At this time, the rotation shaft of the motor 31 extends to both sides, and the first circulation fan 33 and the second circulation fan 34 are coupled to the rotation shafts 32a and 32b extending to both sides, respectively.
이를 좀더 상세히 설명하면, 모터(31)는 냉각실(17)과 냉기 안내유로(18)가 연통되는 이들 상부공간(B)의 대체로 중앙에 설치되고, 제 1순환팬(33)과 제 2순환팬(34)은 모터(31)에서 양측으로 연장된 회전축(32a,32b)에 각각 결합된다. 즉, 모터(31)의 후방(증발기 상부)으로 연장된 회전축(32a)에는 제 1순환팬(33)이 설치되고, 모터(31)의 전방(안내유로 상부)으로 연장된 회전축(32b)에는 제 2순환팬(34)이 설치된다. 그리고 모터(31)의 몸체는 그 외면에서 연장된 다수의 지지봉(35)에 의해 지지된다.In more detail, the motor 31 is installed in the center of the upper space B in which the cooling chamber 17 and the cold air guide passage 18 communicate with each other, and the first circulation fan 33 and the second circulation. The fan 34 is coupled to the rotating shafts 32a and 32b respectively extending from both sides of the motor 31. That is, the first circulation fan 33 is installed in the rotation shaft 32a extending to the rear of the motor 31 (upper evaporator), and the rotation shaft 32b extending in front of the motor 31 (upper guide flow path). The second circulation fan 34 is installed. And the body of the motor 31 is supported by a plurality of support rods 35 extending from the outer surface.
이때, 제 1순환팬(33)과 제 2순환팬(34)은 유체의 유동방향이 급격하게 변하는 유로의 굴곡지점에 각각 설치된다. 이는 냉각실(17)로부터 냉기 안내유로(18)로 흐르는 냉기가 급격하게 선회하는 부분에 각각 순환팬(33,34)이 설치됨으로써 냉기의 송풍효율을 높이기 위함이다. 또한 각 순환팬(33,34)의 주위에는 여유공간이 형성되어 유체의 유동저항을 최소화하는 것이 바람직하며, 모터(31)의 외경은 되도록 작게 하여 유체의 흐름이 원활하도록 하는 것이 바람직하다.At this time, the first circulation fan 33 and the second circulation fan 34 are respectively installed at the bending point of the flow path in which the flow direction of the fluid is rapidly changed. This is to increase the blowing efficiency of the cold air by installing the circulation fans 33 and 34 respectively in the portion where the cold air flowing from the cooling chamber 17 to the cold air guide passage 18 is rapidly turned. In addition, a free space is formed around each of the circulation fans 33 and 34 to minimize the flow resistance of the fluid, and the outer diameter of the motor 31 is preferably small so as to smoothly flow the fluid.
다음은 이와 같이 구성된 본 고안에 따른 냉장고용 냉기 순환장치의 동작을 설명한다.Next will be described the operation of the cold air circulation system for a refrigerator according to the present invention configured as described above.
모터(31)의 구동에 의해 제 1순환팬(33)과 제 2순환팬(34)이 회전되면, 저장실(11)의 냉기는 냉기흡입구(22)를 통해 증발기(16)가 설치된 냉각실(17)로 유입되고, 냉각실(17)로 유입된 냉기는 증발기(16)와 열교환을 하면서 더 차가운 냉기로 변한다. 또한, 냉각실(17)에서 냉각된 냉기는 제 1순환팬(33)과 제 2순환팬(34)을 거쳐 냉기 안내유로(18)로 흐르고, 냉기토출구(21)를 통해 다시 저장실(11)로 공급됨으로써 냉기의 순환이 이루어진다.When the first circulation fan 33 and the second circulation fan 34 are rotated by the driving of the motor 31, the cold air of the storage chamber 11 is provided in the cooling chamber in which the evaporator 16 is installed through the cold air suction opening 22 ( 17 is introduced into the cooling chamber 17, and the cold air is exchanged with the evaporator 16 and is converted into cooler cold. In addition, the cold air cooled in the cooling chamber 17 flows through the first circulation fan 33 and the second circulation fan 34 to the cold air guide flow path 18, and again through the cold air discharge port 21. By supplying to the cold air circulation is made.
이때, 제 1순환팬(33)은 증발기(16) 상부의 냉기를 제 2순환팬(34) 쪽으로 송풍시키고, 제 2순환팬(34)은 제 1순환팬(31)에 의해 송풍된 냉기를 재 송풍하여 냉기 안내유로(18) 및 전방의 냉기토출구(21) 쪽으로 토출시키게 되므로, 냉기의 유동손실이 줄어들고 송풍능력이 크게 향상된다. 즉, 냉각실(17)로부터 냉기 안내유로(18)를 연결하는 유로(순환장치가 설치된 상부공간)가 굴곡유로를 이루더라도, 유체의 흐름방향이 크게 변하는 위치에 제 1순환팬(33)과 제 2순환팬(34)이 설치되기 때문에 냉기의 흐름이 원활해진다.At this time, the first circulation fan 33 blows cold air in the upper portion of the evaporator 16 toward the second circulation fan 34, and the second circulation fan 34 blows the cold air blown by the first circulation fan 31. Since the air is blown again and discharged toward the cold air guide passage 18 and the cold air outlet 21 in front, the flow loss of the cold air is reduced and the air blowing capacity is greatly improved. That is, even if the flow path (upper space in which the circulation device is installed) connecting the cold air guide flow path 18 from the cooling chamber 17 forms a curved flow path, the first circulation fan 33 is positioned at a position where the flow direction of the fluid changes greatly. Since the second circulation fan 34 is installed, the flow of cold air is smooth.
이상에서 상세히 설명한 바와 같이, 본 고안에 따른 냉장고용 냉기 순환장치는 모터의 양측으로 연장된 회전축에 제 1순환팬과 제 2순환팬이 설치되고, 또한 이들 팬이 냉기의 흐름방향이 변하는 굴곡지점에 설치됨으로써, 냉기의 흐름을 원활하게 할 뿐만 아니라 냉기의 송풍능력을 크게 향상시키는 효과가 있다.As described above in detail, the refrigerator cold air circulation system according to the present invention is provided with a first circulation fan and a second circulation fan on the rotating shaft extending to both sides of the motor, the bending point where these fans change the flow direction of cold air By being installed in the above, not only the flow of cold air is smooth, but also the blowing ability of cold air is greatly improved.
