The machine room of the refrigerator is a place where essential components on a refrigeration cycle are provided. In particular, a noise generated by a compressor, a condenser, a blower fan, etc. is strongly generated, and a rotor of the compressor is also provided. Low frequency sound is generated by the eccentric force acting between the reciprocating piston and the horizontal reciprocating motion.The refrigerant gas discharged at high temperature and high pressure is discharged according to the operation of the compressor, and high frequency sound is generated by friction with the inside of the case. In the past, special sound absorbing devices for low frequency and high frequency noise were not installed, which made consumers uncomfortable.
이에 이러한 문제를 해결하기 위하여, 입구부의 반경보다 약 3배 정도 크게 형성된 내부구를 갖는 디퓨전 홀(Diffusion Hole)이 다수 형성된 쉬트(Sheet)를 소정 두께와 크기로 형성하여, 기계실 내부의 필요부위, 이를 테면 상하면, 좌우측면 등에 부착하여서 된 구성이다.In order to solve this problem, by forming a sheet having a plurality of diffusion holes (Diffusion Hole) having a plurality of inner holes formed about three times larger than the radius of the inlet to a predetermined thickness and size, required parts in the machine room, For example, the upper and lower surfaces are attached to the left and right sides.
Description
본 고안은 냉장고의 기계실 소음 차단장치에 관한 것으로, 보다 상세하게는 냉장고의 기계실을 별도의 흡음 혹은 소음차폐 수단을 부착하여서 기계실 내부에서 발생되던 소음을 획기적으로 차단토록 한 냉장고 기계실의 소음 차단장치에 관한 것이다.The present invention relates to a noise canceling device of a machine room of a refrigerator, and more particularly, to a noise blocking device of a refrigerator machine room in which a noise absorbing or noise shielding means is attached to a mechanical room of a refrigerator to block the noise generated inside the machine room. It is about.
도 1에 도시된 바와 같이 일반적인 냉장고의 기계실(10)에는, 냉동싸이클 상의 필수 구성요소로 냉매가스를 고온고압으로 압축하여 주는 압축기(20)를 비롯하여, 고온고압의 냉매가스를 액화시켜주는 방열장치인 콘덴서(30), 이들에 의하여 발생된 고온의 열을 냉각시키기 위한 냉각팬(40) 및 이들 구성요소들을 상호간에 연결시켜 주는 냉매파이프 들이 구비되어 있다.As shown in FIG. 1, the machine room 10 of a general refrigerator includes a compressor 20 for compressing refrigerant gas at high temperature and high pressure as an essential component on a refrigeration cycle, and a heat dissipation device for liquefying refrigerant gas at high temperature and high pressure. Phosphor condenser 30, a cooling fan 40 for cooling the high temperature heat generated by them, and refrigerant pipes that connect these components with each other are provided.
따라서, 고내를 냉각시키기 위하여 작동되는 일련의 냉동싸이클 상의 필수 구성요소들에 의하여 기계실(10) 내부는 저주파를 비롯하여 고주파의 영역에 이르는 소음이 발생되는 바, 특히 압축기(20)는 피스톤과 실린더, 이와 편심을 이루며 운동을 하게 되는 회전자 그리고 머플러, 써스펜션 등으로 구성되어 회전자와 수평왕복운동을 하는 피스톤 사이의 편심력에 의하여 발생하는 약 50∼60㎐정도인 저주파음 및 냉각팬(40)의 저주파음과, 피스톤의 수평왕복운동에 의하여 압축된 고온고압의 냉매가 케이스의 내부를 향하여 강하게 분사되면서 케이스 상면과의 마찰로 발생하는 약 2.5∼4㎑ 정도의 고주파음 등이 기계실(10) 내벽에는 반사되면서 증폭되어 더 많은 소음이 발생하는 바, 종래에는 이러한 소음에 대한 방지대책이 마련되어 있지 않아 소비자에게 불편을 초래하는 문제를 야기시켰다.Therefore, the essential components on the series of refrigeration cycles operated to cool the inside of the machine room 10 generate noises ranging from the low frequency to the high frequency region. Particularly, the compressor 20 includes a piston, a cylinder, The low frequency sound and cooling fan (40) of about 50 to 60 Hz generated by the eccentric force between the rotor and the piston to make the eccentric movement and the piston to the horizontal reciprocating movement The high frequency and high pressure refrigerant generated by friction with the upper surface of the case while the high frequency and high pressure refrigerant compressed by the horizontal reciprocating motion of the piston is strongly injected toward the inside of the case are machine rooms 10. As the inner wall is reflected and amplified to generate more noise, conventionally, there are no measures to prevent such noise. Crab caused a problem that causes inconvenience.
본 고안은 상술한 바와 같은 제반 문제점 들을 감안하여 이를 해결하고자 안출된 것으로, 냉장고의 기계실 내부에서 발생되는 소음 중 특히, 고주파 영역의 소음을 효과적으로 차단할 수 있는 차단장치의 제공을 그 기술적 과제로 한다.The present invention has been made in view of the above-described problems, and the technical problem is to provide a blocking device that can effectively block the noise in the high frequency region of the noise generated inside the machine room of the refrigerator.

본 고안은 상기한 기술적 과제를 실현하기 위하여, 냉장고의 기계실에서 발생된 소음을 제거하기 위한 장치에 있어서, 상기 기계실의 상면, 전면, 좌우측면 전체나 혹은 일부면에 디퓨전 홀이 형성된 흡음쉬트를 부착하는 것을 특징으로 한다.The present invention, in order to realize the above technical problem, in the apparatus for removing the noise generated in the machine room of the refrigerator, the sound absorbing sheet having a diffusion hole is formed on the entire surface, the front, left and right or part of the machine room. Characterized in that.
이하에서는, 본 고안에 다른 바람직한 일 실시예를 첨부한 도면을 참조하여 보다 상세히 설명한다.Hereinafter, with reference to the accompanying drawings another preferred embodiment of the present invention will be described in more detail.
도시한 도 2는 본 고안에 따른 흡음쉬트(60)의 부착상태를 도시한 것이며, 도 3 및 도 4는 본 고안의 요부구조를 확대 도시한 것이다.Figure 2 shows the attached state of the sound absorbing sheet 60 according to the present invention, Figures 3 and 4 is an enlarged view of the main structure of the present invention.
본 고안은 상기한 도 2 내지 도 4에서와 같이, 내열성이 강하고 탄성이 뛰어난 합성수지류와 비중이 낮은 천연고무류를 이용하여 물병모양의 디퓨전 홀(Diffusion Hole)(90)을 가진 흡음쉬트(60)를 기계실(10)의 적정 부위에 부착하여서 된 것이다.2 to 4, the present invention is a sound absorption sheet having a water-hole-type diffusion hole 90 using synthetic resins having high heat resistance and excellent elasticity and natural rubber having a low specific gravity. It is made by attaching to the appropriate part of the machine room 10.
한편, 이러한 흡음쉬트(60)의 후면에는 접착제(80)를 처리하여 부착 설치가 용이하도록 구성된 것이다.On the other hand, the back of the sound absorbing sheet 60 is configured to facilitate the installation by treating the adhesive (80).
아울러, 상기한 디퓨전 홀(90)의 형상 및 크기는 다음과 같은 계산에 의하여 형성된다.In addition, the shape and size of the diffusion hole 90 is formed by the following calculation.
즉, 도 4의 가부 상세도에서와 같이, 디퓨전 홀(90)은 그 형상이 작은 물병 모양으로 구성되면서 그 입구부의 반경(R1)과 내부의 반경(R2)의 비는That is, as shown in the provisional detail of FIG. 4, the diffusion hole 90 has a shape of a small water bottle, and the ratio of the radius R 1 and the radius R 2 of the inlet portion is
R2=(2.5∼3)×R1 R 2 = (2.5 to 3) x R 1
(여기에서, R2는 내부의 반경을 말하고, R1는 입구부의 반경을 말한다.)(Here, R 2 refers to the radius inside and R 1 refers to the radius of the inlet.)
따라서, 입구부의 반경보다 내부의 반경이 크게 형성된 디퓨전 홀(90)이 천연고무판이나 합성수지판에 다수 형성되어 있으며, 그 두께는 기계실(10) 내부 소음정도에 따라 적정하게 조정할 수가 있다.Therefore, a large number of diffusion holes 90 having a larger inner radius than the radius of the inlet are formed in the natural rubber plate or the synthetic resin plate, and the thickness thereof can be appropriately adjusted according to the noise level inside the machine room 10.
이러한 구성으로 이루어진 본 고안은, 기계실(10) 내부의 상면, 전면, 좌,우 측면에 각각 원하는 만큼 그 후면에 형성된 접착제(80)를 통하여 부착고정하면 된다.The present invention made of such a configuration, the upper surface, the front, left, right side of the inside of the machine room 10 may be fixed through the adhesive 80 formed on the rear side as desired.
이렇게 부착된 흡음쉬트(60)는 압축기(20)에서 발생된 소음이 기계실(10) 내부면으로 반사되면서 다수의 디퓨전 홀(90)이 형성된 흡음쉬트(60)의 홀안으로 유입된다.The sound absorbing sheet 60 attached as described above is introduced into the hole of the sound absorbing sheet 60 in which a plurality of diffusion holes 90 are formed while the noise generated from the compressor 20 is reflected to the inner surface of the machine room 10.
이때, 유입된 소음은 도시한 도 4와 같이 화살표 모양으로 확산되는 바, 이는 흑체복사에서와 같은 형태로 입구부를 통하여 한 번 유입된 소음을 일으키는 파동은 입구부보다 상당히 크게 형성된 내부를 통하여 확산되면서 반사를 반복하게 되고 따라서 결국에는 이러한 디퓨전 홀(90)에 갇히게 되는 현상이 되는 것이다.At this time, the introduced noise is spread in the shape of an arrow as shown in Figure 4, which is a wave that causes the noise once introduced through the inlet in the form as in the black body radiation is spread through the interior formed significantly larger than the inlet The reflection is repeated, and thus eventually becomes trapped in the diffusion hole 90.
이러한 관계를 수식을 통하여 다시 설명한다면, 디퓨전 홀(90)의 입구면적은 (R1/2)2π이고, 그 내부구의 면적은 4×(R2/2)2π이므로 R2에 상술한 식을 대입하면 내부 구의 면적은 입구 면적의 25∼36배 정도가 넓어지게 됨을 알 수 있다.If other words of this relationship through the equation, the inlet area of the diffusion holes 90 (R 1/2) and 2 π, the inner sphere area, so 4 × (R 2/2) 2 π above for R 2 Substituting the equation, the inner sphere becomes 25 to 36 times larger than the entrance area.
이렇게 확산 홀의 안으로 유입된 소음은 확산된 표면에 흡수되어 소멸하게 된다. 만약, 반사가 된다해도 항아리의 구조안에서 입구 밖으로 유출되기 어렵게 된다. 따라서, 기계실(10) 내부에서 발생된 소음은 획기적으로 감소하게 되는 것이다.The noise introduced into the diffusion hole is absorbed by the diffused surface and disappears. If it is reflected, it will be difficult to flow out of the entrance in the structure of the jar. Therefore, the noise generated inside the machine room 10 is to be significantly reduced.
이상에서 살펴 본 바와 같이, 본 고안에 따른 냉장고의 확산 홀을 이용한 접착용 흡음쉬트는, 일정간격을 유지하며 형성된 디퓨전 홀의 구조에서 기계실 부 소음의 상단부분은 디퓨전 홀 안으로 흡수되므로 기계실 내에서 발생할 수 있는 공진현상이 억제되므로 기계실부의 소음차단과 저감효과는 크다고 할 수 있으며, 흡음쉬트 뒷면에 접착제 처리를 하여 작업도 용이하게 되는 효과가 있으며, 아울러, 냉장고 소음의 대다수를 차지하고 있는 기계실부 소음을 차단하여 조용하고 쾌적한 냉장고 환경을 유지토록 하는 효과가 있다.As described above, the sound absorbing sheet for bonding using the diffusion hole of the refrigerator according to the present invention, in the structure of the diffusion hole formed while maintaining a constant interval, the upper part of the noise in the machine room may be generated in the machine room because it is absorbed into the diffusion hole. Since the resonance phenomenon is suppressed, the noise reduction and reduction effect of the machine room part can be said to be large, and the effect of the adhesive treatment on the back of the sound absorbing sheet is also easy to work, and the noise of the machine room, which occupies most of the refrigerator noise, is blocked. The effect is to maintain a quiet and comfortable refrigerator environment.
