Description
본 고안은 냉장고의 송풍팬 설치구조에 관한 것으로 보다 상세하게는 부품수를 줄여 조립공정을 간소화한 냉장고의 송풍팬 설치구조에 관한 것이다.The present invention relates to a blower fan installation structure of the refrigerator, and more particularly to a blower fan installation structure of the refrigerator simplified the assembly process by reducing the number of parts.
일반적으로, 냉장고의 냉기순환은 압축기에서 토출된 고온고압의 냉매가스가 응축기를 통과하면서 외부로 열이 방출되어 고압의 액냉매로 액화된 후에 드라이버를 통과하면서 고압의 액냉매는 불순물과 수분등이 제거되고 모세관을 거치며, 모세관을 거치는 동안 냉매는 증발하기 쉬운 기액혼합상태로 되어 증발기를 통하여 주변의 열을 흡수 열교환시키며 가스화 된다.In general, the cold air circulation of the refrigerator is a high-temperature high-pressure refrigerant gas discharged from the compressor through the condenser, the heat is released to the outside to liquefy into a high-pressure liquid refrigerant, and then through the driver, the high-pressure liquid refrigerant is free of impurities and moisture The refrigerant is removed and passes through a capillary tube, and while the capillary tube is passed, the refrigerant is in a gas-liquid mixed state, which is easily evaporated, and absorbs heat from the surrounding heat through the evaporator, thereby gasifying.
이 과정에서 증발기 주위의 냉기가 냉각되고 송풍팬에 의하여 송풍된 냉기는 냉장고내에 토출되어 냉장고내를 저온으로 유지시키며, 열교환 후 온도가 상승된 냉기를 귀환덕트를 통하여 증발기측으로 흡입되어 냉각되는 순환반복의 냉기순환사이클이 진행되는 것이다.In this process, the cold air around the evaporator is cooled and the cold air blown by the blower fan is discharged into the refrigerator to keep the inside of the refrigerator at a low temperature, and after the heat exchange, the cold air whose temperature has risen is sucked to the evaporator side through the return duct to be cooled repeatedly. The cold air circulation cycle is in progress.
이러한 냉기순환사이클에 있어서, 증발기측에 냉각된 냉기를 냉장고 내부로 공급시키는 송풍팬은 도1의 도시와 같이, 송풍팬(11)의 팬모터(1)가 전후의 브라켓(14)(15)에 고정된 상태에서 그 구동축이 전후측에 부싱(12)에 의해 회전가능하게 고정되고 상기 전방브라켓(14)의 플랜지부에서 송풍팬(11) 외측까지 벨마우스(16)가 설치되는데 상기 벨마우스(16)는 그 선단의 씰링(13)은 개재하여 루버절연물(24)의 개구에 고정되어 있다.In this cold air circulation cycle, the blower fan for supplying the cool air cooled on the evaporator side to the inside of the refrigerator, as shown in Figure 1, the fan motor 1 of the blower fan 11 before and after the bracket (14, 15) In the state fixed to the drive shaft is rotatably fixed to the front and rear by the bushing (12) and the bell mouse 16 is installed from the flange of the front bracket 14 to the outside of the blowing fan 11, the bell mouse Numeral 16 is fixed to the opening of the louver insulator 24 via the sealing 13 at its tip.
도면부호 20은 냉장고의 외상이고, 21은 상기 브라켓(14)(15)이 그 요부에 수납된 상태에서 나사(17)로 고정되는 내상이다.Reference numeral 20 denotes an outer box of the refrigerator, and 21 denotes an inner box fixed by a screw 17 in a state where the brackets 14 and 15 are accommodated in the recess.
그러나 이와 같은 종래의 송풍팬 설치구조는 송풍팬(11) 회전시 송풍팬(11)에 의하여 냉동실로 공급되는 냉기의 분산을 방지하기 위한 벨마우스(16)가 설치되어야 하고 상기 벨마우스(16)는 씰링(13)을 개재하여 루버절연물(24)에 고정되는 등 부품수가 많고 조립이 번거로워 생산성 저하는 물론 제품의 원가상승을 초래되었다.However, such a conventional blower fan installation structure requires a bell mouse 16 to be prevented from dispersing cold air supplied to the freezer compartment by the blower fan 11 when the blower fan 11 rotates, and the bell mouse 16 is installed. The number of parts, such as being fixed to the louver insulator 24 via the sealing 13 and the assembly is cumbersome, resulting in a decrease in productivity and a cost increase of the product.
본 고안은 이와 같은 종래 문제점을 감안하여 안출된 것으로서, 냉장고의 송풍팬 설치되는 부품을 단순화하여 부품수를 줄이고 조립을 간편하게 냉장고의 송풍팬 설치구조를 개선하는 것을 그 기술적 과제로 한다.The present invention has been made in view of such a conventional problem, and the technical problem is to simplify the parts to be installed in the blower fan of the refrigerator to reduce the number of parts and to easily improve the assembly structure of the blower fan of the refrigerator.

상기한 기술적 과제를 해결하기 위하여 본 고안에 따른 냉장고의 송풍팬 설치구조는 그 축에 부싱을 개재하여 고정하는 전후 브라켓이 냉장고의 내상에 나사로 고정됨으로써 냉장고의 내상에 고정되는 팬모터의 회동축에 설치된 송풍팬에 있어서, 상기 송풍팬 정면의 개구가 송풍팬 외측에 인접하여 감싸도록 냉동실측으로 절곡연장되고 다시 중앙으로 절곡되어 다수의 장홈을 형성한 커버가 일체로 형성된 수납부를 냉장고의 냉동실 배면의 루버와 일체로 형성한 것을 특징으로 한다.In order to solve the above technical problem, a blower fan installation structure of the refrigerator according to the present invention includes a front and rear bracket for fixing through a bushing on a shaft thereof to a rotation shaft of a fan motor fixed to an inner portion of a refrigerator by fixing screws with an inner portion of the refrigerator. In the installed blower fan, the louver at the rear of the freezer compartment of the refrigerator freezer unit is a storage unit formed integrally with a cover that is bent to the freezer compartment side to be folded adjacent to the outside of the blower fan and then bent to the center to form a plurality of long grooves integrally Characterized in that formed integrally with.
또한 본 고안의 루버는 일정두께의 절연재가 상기 루버와 일체로 형성되거나 그 배면이 일체로 부착되는 것이다.In addition, the louver of the present invention is that the insulating material of a predetermined thickness is integrally formed with the louver or the back thereof is integrally attached.
이하, 본 고안 실시예에 따라 도시하여 첨부한 도면을 참조하여 보다 구체적으로 설명한다.Hereinafter, with reference to the accompanying drawings shown in accordance with an embodiment of the present invention will be described in more detail.
도2는 본 고안의 송풍팬 설치구조를 도시한 단면도이고, 도3은 요부분리사시도로서, 냉장고의 내상(21) 요부에 그 플랜지부가 나사(17)로 고정된 전후양측의 브라켓(14)(15)에 그 회동축에 부싱(12)을 개재한 상태로 팬모터(1)가 고정되어 있다.Fig. 2 is a sectional view showing a blower fan installation structure of the present invention, and Fig. 3 is a partial perspective view showing brackets 14 on both sides of the front and rear sides of which a flange portion is fixed to a main portion of an inner portion 21 of a refrigerator by screws 17 The fan motor 1 is fixed to the rotating shaft 15 with the bushing 12 interposed therebetween.
상기 팬모터(1)의 회동축 선단에는 송풍팬(11)이 삽입고정되는데, 상기 송풍팬(11)은 절연재(31)가 일체로 부착된 루버(23)의 개구를 관통하여 냉장실측으로 돌출되어 있는데, 상기 송풍팬(11)의 외측에 인접하여 형성된 루버(23)의 개구가 냉동실측으로 절곡되어 송풍팬(11)을 둘러싸며 중앙으로 절곡되어 장홈(29)이 다수 형성된 커버(28)를 일체로 형성한 수납부(30)에 송풍팬(11)이 설치되어 있다.A blowing fan 11 is inserted and fixed at the tip of the rotational shaft of the fan motor 1, and the blowing fan 11 penetrates through the opening of the louver 23 to which the insulating material 31 is integrally protruded to the refrigerating chamber side. The opening of the louver 23 formed adjacent to the outside of the blower fan 11 is bent toward the freezer compartment to surround the blower fan 11 and bent toward the center to integrally cover the cover 28 having a plurality of long grooves 29. The blowing fan 11 is provided in the accommodating part 30 formed with the stiffener.
상기 수납부(30)는 냉동실로 공급되는 냉기의 분산을 막아주게 되고 또한 수납부(30)에 일체로 연장현성된 커버(28)의 장홈(29)을 통해 냉기가 냉동실측으로 공급되게 된다.The accommodating part 30 prevents the distribution of cold air supplied to the freezing compartment and also supplies the cold air to the freezing compartment side through the long groove 29 of the cover 28 extending and formed integrally with the accommodating part 30.
그러므로 본 고안에서는 냉기의 분산을 막아주기 위한 벨마우스나 씰링 또는 루버절연물의 설치필요성이 제거되어 송풍팬 설치구조의 단순화가 가능하게 되는 것이다.Therefore, the present invention eliminates the need for installation of a bell mouse, sealing or louver insulator to prevent cold air dispersion, thereby simplifying the installation structure of the blower fan.
이상에서 상세히 설명한 바와 같이, 본 고안 냉장고의 송풍팬 설치구조는 송풍팬 정면의 루버에 형성된 개구를 냉동실측으로 절곡하여 다수 중앙으로 절곡하여 다수의 장홈을 형성한 수납부를 루버와 일체로 형성하여 이에 상기 송풍팬을 설치함으로써, 별도의 벨마우스나 씰링 또는 루버절연물의 설치필요성이 제거되어 송풍팬 설치구조의 단순화가 가능하게 되고 부품수 감소로 인한 조립공정수가 줄어들어 생산성 향상 및 제조원가의 절감을 기할 수 있는 유용하고 실용적인 고안이다.As described above in detail, the blower fan installation structure of the present invention refrigerator forms an accommodating portion integrally formed with the louver by bending the opening formed in the louver at the front of the blower fan toward the freezer compartment to be bent to a plurality of centers. By installing a blower fan, the need for installing a separate bell mouse or sealing or louver insulator can be eliminated, simplifying the blower fan installation structure and reducing the number of assembly processes due to the reduction of the number of parts. It is a useful and practical design.
본 고안은 송풍팬이 설치되는 부분의 구조를 단순화하여 부품수가 적어 조립공정수가 줄어들고 생산성의 향상과 제조원가를 절감할 수 있는 냉장고의 송풍팬 설치구조의 제공을 그 목적으로 한다.The present invention aims to provide a blower fan installation structure of the refrigerator which can simplify the structure of the part where the blower fan is installed to reduce the number of parts and reduce the number of assembly processes and improve productivity and reduce manufacturing costs.
