Description
본 고안은 냉장고의 팬모터의 진동을 방지하는 방진고무에 관한 것이다.The present invention relates to a dustproof rubber to prevent vibration of the fan motor of the refrigerator.
일반적으로, 냉장고에는 고내의 공기를 증발기로 순환시켜 냉기를 형성시킨 후 이를 냉동실 및 냉장실로 공급시키는 팬모터가 설치된다. 이 팬모터는 냉동실의 후측에 고정 설치되는데, 제1도에서와 같이 팬모터(10)의 전후로 팬모터(10)를 고정하는 전면 및 후면 팬모터 커버(30)(40)가 구비되어 팬모터(10)를 냉동실 후측내상에 나사고정시킨다. 이와 같이 고정된 팬모터(10)는 전후로 회전축(12)단을 지지하기 위해 축지지부(11)가 돌출 형성되어 있는데, 전면 및 후면 팬모터 커버(30)(40)에는 축지지부(11)가 삽입되는 팬모터 고정구멍(32)(42)이 각각 형성되어 있다.In general, a refrigerator is provided with a fan motor that circulates air in a refrigerator with an evaporator to form cold air and then supplies it to a freezing compartment and a refrigerating compartment. The fan motor is fixedly installed at the rear side of the freezer compartment, and as shown in FIG. 1, the front and rear fan motor covers 30 and 40 which fix the fan motor 10 before and after the fan motor 10 are provided with the fan motor. Screw (10) onto the inside of the freezer compartment. The fan motor 10 fixed as described above has a shaft support part 11 protruding from the front and rear to support the end of the rotation shaft 12. The front and rear fan motor covers 30 and 40 have a shaft support part 11. Fan motor fixing holes 32 and 42 to be inserted are formed, respectively.
이러한 구조로 조립된 팬모터(10)는 작동시 내부의 회전자(도면에 도시 안됨)와 회전축(12) 및 회전축(12)의 단부에 결합된 회전날개(14)가 회전되면서 진동이 발생하게 되는데, 이 진동은 전면 및 후면 팬모터 커버(30)(40)에 전달되어 내상으로 전달되고, 이는 다시 냉장고 캐비넷(도면에 도시 안됨)으로 전달되면서 중폭되어 심한 냉장고의 소음을 형성하게 된다. 이와 같은 현상을 방지하기 위해 팬모터(10)의 전후면에 돌출 형성된 축지지부(11)와 전면 및 후면 팬모터 커버이 팬모터 고정구멍(32)(42)의 사이에 방진고무(20)를 개재하여 팬모터(10)에서 발생하는 진동을 흡수하도록 하였다.The fan motor 10 assembled in such a structure causes vibrations while the inner rotor (not shown) and the rotary blade 14 coupled to the rotary shaft 12 and the end of the rotary shaft 12 rotate during operation. This vibration is transmitted to the front and rear fan motor cover 30, 40 is transmitted to the internal wound, which is transmitted back to the refrigerator cabinet (not shown in the drawing), which is severely formed to form a noise of the severe refrigerator. In order to prevent such a phenomenon, the axial support part 11 protruding from the front and rear surfaces of the fan motor 10 and the front and rear fan motor covers are interposed between the fan motor fixing holes 32 and 42 with a dustproof rubber 20. By absorbing the vibration generated in the fan motor (10).
이와 같이 팬모터(10)의 진동을 흡수하는 방진고무(20)의 구조를 보면 종래에는 제2도에서와 같이 내부에 팬모터(10)의 축지지부(11)를 삽입하는 내측관(22)이 형성되고, 내측관(22)의 전면 또는 후면 팬모터 커버(30)(40)쪽 단부에서 뒤집어져 내측관(22) 외주연과 이격되게 연장된 진동흡수부(24)가 형성되며, 진동흡수부(24)의 단부로 팬모터(10)에 밀착되는 플랜지(28)가 일체로 형성되어 있다. 이때, 팬모터(10)방향의 플랜지(28)면에는 방사형태의 리브(26)가 형성되어 있다.As described above, when the structure of the anti-vibration rubber 20 absorbing the vibration of the fan motor 10 is conventional, the inner tube 22 inserting the shaft support 11 of the fan motor 10 therein as shown in FIG. 2. Is formed, the vibration absorbing portion 24 is formed to be inverted at the front end or rear fan motor cover 30, 40 side end of the inner tube 22 and spaced apart from the outer periphery of the inner tube 22, the vibration The flange 28 which is in close contact with the fan motor 10 is formed integrally with the end of the absorbing portion 24. At this time, a radial rib 26 is formed on the flange 28 surface in the fan motor 10 direction.
이와 같은 구조의 방진고무(20)는 플랜지(28)가 팬모터(10)쪽을 향하도록 하여 내측관(22)이 팬모터(10)의 양측 축지지부(11) 외주에 각각 끼워진다. 팬모터(10)의 축지지부(11)에 방진고무(20)가 끼워지게 되면 방진고무(20)의 진동흡수부(24)의 외주로 전면 및 후면 팬모터 커버(30)(40)의 팬모터 고정구멍(32)(42)이 끼워짐으로 팬모터(10)는 방진고무(20)에 의해 지지된다.The anti-vibration rubber 20 of such a structure is such that the flange 28 faces the fan motor 10 so that the inner tube 22 is fitted on the outer circumference of both shaft supports 11 of the fan motor 10. When the anti-vibration rubber 20 is fitted to the shaft support part 11 of the fan motor 10, the fan of the front and rear fan motor covers 30 and 40 is the outer circumference of the vibration absorbing part 24 of the anti-vibration rubber 20. Since the motor fixing holes 32 and 42 are fitted, the fan motor 10 is supported by the anti-vibration rubber 20.
또한, 팬모터(10)가 고정된 상태에서 팬모터(1)의 작동에 의한 진동이 발생되면 그 진동은 방진고무(20)에 전달된다. 이때, 방진고무(20)의 구조가 내측관(22)의 단부가 뒤집어지는 구조로 역절곡되어 내측관(22)의 외주와 일정한 간격을 유지하며 연장된 있으므로 진동은 진동흡수부(24)의 절곡된 부위에서 흡수하게 된다.In addition, when the vibration caused by the operation of the fan motor 1 in the fan motor 10 is fixed, the vibration is transmitted to the anti-vibration rubber (20). At this time, since the structure of the anti-vibration rubber 20 is reversely bent in a structure in which the end of the inner tube 22 is inverted to maintain a constant distance from the outer circumference of the inner tube 22, the vibration of the vibration absorbing part 24 is increased. Absorbed at the bent area.
그러나, 팬모터(10)는 무게가 무거우므로 팬모터(10)의 축지지부(11)가 삽입된 방진고무(20)의 내측관(22)은 하부로 처지게 되어 플랜지(28)가 형성되는 진동흡수부(24)의 단부에 내리 않게 된다. 이와 같은 현상에 의해 팬모터(10)의 진동은 방진고무(20)의 진동흡수부(24)에서 흡수하지 못하고 그대로 전면 및 후면 팬모터 커버(30)(40)에 전달되고 이는 내상을 통해 케비닛(도면에 도시 안됨)으로 전달되어 증폭되게 됨으로 냉장고의 소음은 가중된다.However, since the fan motor 10 is heavy, the inner tube 22 of the anti-vibration rubber 20 in which the shaft support 11 of the fan motor 10 is inserted sags downward to form a flange 28. It does not fall to the end of the vibration absorbing portion 24 to be. Due to this phenomenon, the vibration of the fan motor 10 is not absorbed by the vibration absorbing part 24 of the anti-vibration rubber 20 and is transmitted to the front and rear fan motor covers 30 and 40 as it is. The noise of the refrigerator is aggravated by being transferred to the vignette (not shown) and amplified.
본 고안은 이와 같은 종래의 폐단을 해소하고자 안출된 것이다.The present invention is devised to solve such a conventional waste.
본 고안의 목적은 팬모터의 진동을 흡수하는 방진고무에 진동흡수부를 이중으로 두어 팬모터의 무게가 무겁더라도 발생된 진동을 흡수할 수 있도록 하는 냉장고의 팬모터 방진고무를 제공하는데 있다.It is an object of the present invention to provide a fan motor anti-vibration rubber of the refrigerator so as to absorb the vibration generated even if the weight of the fan motor by placing a double vibration absorbing portion in the anti-vibration rubber absorbing the vibration of the fan motor.

이하, 본 고안의 바람직한 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention in detail as follows.
제4도를 참조하면, 제3도는 본 고안에 따른 방진고무의 구조를 나타낸 방진고무(80)의 단면사시도로서, 참조번호 10은 축지지부(11)를 구비한 팬모터의 일부를 나타낸 것이고, 30 및 40 은 팬모터 고정구멍(32)(42)이 형성된 전면 및 후면 팬모터 커버이다.Referring to Figure 4, Figure 3 is a cross-sectional perspective view of the anti-vibration rubber 80 showing the structure of the anti-vibration rubber according to the present invention, the reference numeral 10 shows a part of the fan motor having a shaft support portion 11, 30 and 40 are front and rear fan motor covers in which fan motor fixing holes 32 and 42 are formed.
본 고안의 방진고무(80)는 내부에 모터의 전후에 돌출된 축지지부(11)에 끼워지는 내측관(82)이 형성되어 있고, 그 욉에 내측관(82)의 일측단과 연결된 진동흡수부(84)가 일체로 형성되어 있으며, 진동흡수부(84)의 단부에는 팬모터(10)에 밀착되는 플랜지(88)가 일체로 형성되어 있다.The anti-vibration rubber 80 of the present invention has an inner tube 82 that is fitted to the shaft support portion 11 protruding from the front and rear of the motor therein, and the vibration absorbing portion connected to one end of the inner tube 82 therein. 84 is formed integrally, and the flange 88 which is in close contact with the fan motor 10 is integrally formed at the end of the vibration absorbing portion 84.
방진고무(80)의 진동흡수부(84) 형상을 보면 2중으로 절곡된 구조를 갖는데, 내측관(82)의 팬모터(10)쪽 단부가 뒤집어지는 구조로 역절곡된 1차절곡부(85)가 형성되고, 1차절곡부(85)에서 내측관(82)의 외주연과 간격을 유지하면서 내측관(82) 단부쪽으로 연장되다가 다시 뒤집어지는 구조로 역절곡되어 1차절곡부(85)에서 연장된 부위의 외주연과 간격을 유지하면서 팬모너(10)쪽으로 연장된 구조로 되어 있다.Looking at the vibration absorbing portion 84 shape of the anti-vibration rubber 80 has a double bent structure, the first bent portion (85) reversely bent in a structure that the end of the fan motor 10 side of the inner tube 82 is reversed ) Is formed, and the first bent portion (85) is reversely bent in a structure that extends toward the end of the inner tube (82) and is turned over again while maintaining a distance from the outer circumference of the inner tube (82) in the primary bent portion (85). It has a structure extending toward the fan motor 10 while maintaining a gap with the outer periphery of the extended portion.
또한, 방진고무(80)의 2차절곡부(86)에서 연장된 단부에 팬모터(10)면에 접촉되는 플랜지(88)가 일체로 형성된다. 이때, 방진고무(80)의 내측관(82) 내경에는 전후로 팬모터(10)의 축지지부(11)에 밀착되는 링형상의 방진리브(83)가 다수개 설치되어 있으며, 팬모터(10)쪽의 플랜지(88)면에는 리브(89)가 방사형태로 다수개 형성되어 있다.In addition, a flange 88 in contact with the fan motor 10 surface is integrally formed at the end portion extending from the secondary bent portion 86 of the anti-vibration rubber 80. At this time, the inner diameter of the inner tube 82 of the anti-vibration rubber 80 is provided with a plurality of ring-shaped anti-vibration ribs 83 in close contact with the shaft support portion 11 of the fan motor 10, the fan motor 10 A plurality of ribs 89 are formed radially on the side of the flange 88 side.
이와 같은 구조의 방진고무(80)는 제4도에서와 같이 팬모터(10)와 전면 및 후면 팬모터 커버(30)(40)의 사이에 개재된다. 즉, 팬모터(10)의 전후부에 돌출 형성된 축지지부(11)의 외주에 각 방진고무(80)의 내측관(82)을 끼우고, 각 방진고무(80)의 진동흡수부(84) 외주에 전면 팬모터 커버(30)와 후면 팬모터 커버(40)에 각각 형성된 팬모터 고정구멍(32)(42)을 끼운 다음, 전면 팬모터 커버(30)(40)와 후면 팬모터 커버(30(40)이 양측을 내상에 밀착시켜 고정나사(58)로 체결 고정시킨다.The dustproof rubber 80 having such a structure is interposed between the fan motor 10 and the front and rear fan motor covers 30 and 40 as shown in FIG. That is, the inner tube 82 of each of the anti-vibration rubber 80 is inserted into the outer circumference of the shaft support portion 11 protruding from the front and rear of the fan motor 10, the vibration absorbing portion 84 of each of the anti-vibration rubber 80 Insert the fan motor fixing holes 32 and 42 formed in the front fan motor cover 30 and the rear fan motor cover 40 on the outer circumference, and then the front fan motor cover 30 and 40 and the rear fan motor cover ( 30 (40) is in close contact with both sides on the inside fastening and fixing with a set screw (58).
전술한 바와 같이 조립된 팬모터(10)가 작동하여 진동이 발생되면, 그 진동은 축지지부(11)를 통해 방진고무(80)에 전달되고 방진고무(80)는 진동을 흡수한다.When vibration is generated by operating the fan motor 10 assembled as described above, the vibration is transmitted to the anti-vibration rubber 80 through the shaft support 11 and the anti-vibration rubber 80 absorbs the vibration.
방진고무(80)의 진동흡수작용은 크게 4단계로 흡수되는데, 일차로 방진고무(80)의 내측관(82)이 팬모터(10)의 축지지부(11)에 끼워진 상태가 내측관(82) 내주연 전면이 팬모터(10)의 축지지부(11)에 접촉되는 것이 아니라, 내측관(82)의 내주연에 형성된 다수개의 링형 방진리브(83)가 접촉되기 때문에 링형 방진리브(83)에 의해 진동이 흡수된다. 이차로는 방진고무(80)위 내측관(82) 일측단이 뒤집어지는 구조로 역절곡된 1차절곡부(85)가 진동을 흡수한다. 이는 진동이 전달되면 1차절곡부(85)가 자체탄성력에 의해 유동되면서 진동을 흡수한다. 삼차로 2차절곡부(86)에서 1차절곡부(85)와 동일한 작용으로 진동을 흡수한다. 사차로 방진고무(80)의 플랜지(88)가 팬모터(10)면에 접촉되어 그 접촉력으로 방진고무(80)의 진동흡수부(84)를 지지하고 있는데 팬모터(10)와 접촉되는 플랜지(88)면에는 방사형태로 리브(89)가 다수개 형성되어 있어 진동을 흡수하게 된다.Vibration absorption action of the anti-vibration rubber 80 is largely absorbed in four stages, the inner tube 82 of the anti-vibration rubber 80 is fitted to the shaft support portion 11 of the fan motor 10 is the inner tube 82 The ring-shaped anti-vibration rib 83 is formed because the entire inner circumferential front surface is not in contact with the shaft support 11 of the fan motor 10, but a plurality of ring-shaped anti-vibration ribs 83 are formed in the inner circumference of the inner tube 82. The vibration is absorbed by this. Secondarily, the reverse bending portion of the primary bent portion 85 has a structure in which one side end of the inner tube 82 on the anti-vibration rubber 80 absorbs vibration. This is when the vibration is transmitted, the primary bent portion 85 flows by its own elastic force and absorbs the vibration. Thirdly, the secondary bent portion 86 absorbs vibrations by the same action as the primary bent portion 85. The flange 88 of the anti-vibration rubber 80 is in contact with the fan motor 10 surface and supports the vibration absorbing portion 84 of the anti-vibration rubber 80 by the contact force, which is in contact with the fan motor 10. A plurality of ribs 89 are formed in the radial surface 88 to absorb vibrations.
또한, 팬모터(10)는 무게가 많이 나가므로 축지지부(11)를 지지하고 있는 내측관(82)이 하부로 처지게 되는 현상이 발생하게 된다. 이때 전면 팬모터 커버(30)와 후면팬모터 커버(40)가 진동흡수부(84)의 외주를 지지하고 있기 때문에 내측관(82)의 바깥쪽 단부가 2차절곡부(86)에 닫게 된다. 그래서 팬모터(10)의 진동은 직접 2차절곡부(86)에 전달되지만 2차절곡부(86)에서 이와같이 전달되는 진동을 흡수하기 때문에 진동은 전면 및 후면 팬모터 커버(30)(40)에 전달되지 못한다.In addition, since the fan motor 10 weighs a lot, a phenomenon in which the inner tube 82 supporting the shaft support part 11 sags downward. At this time, since the front fan motor cover 30 and the rear fan motor cover 40 support the outer circumference of the vibration absorbing unit 84, the outer end of the inner tube 82 is closed to the secondary bent part 86. . Thus, the vibration of the fan motor 10 is directly transmitted to the secondary bent portion 86, but the vibration is absorbed in this way from the secondary bent portion 86, the vibration is the front and rear fan motor cover 30, 40 Not delivered to.
