본 고안은 냉장고 및 냉동기등의 기기에 설치되어 냉동기유 즉, 냉매를 압축시키는 밀폐형 전동 압추기에 있어서, 냉동기유가 밀폐헝 전동 압축기로 홉입되면서 발생되는 소음을 경감시키는 밀폐형 전동 압축기의 소음 경감 장치에 관한 것이다.The present invention provides a noise reduction device for a hermetic electric compressor installed in equipment such as a refrigerator and a refrigerator to reduce the noise generated when the refrigerant oil is fed into the hermetic electric compressor. It is about.

종래의 소옴 경감 장치는 제1도의 (a,b)에 도시된 바와같이 일측의 유입구(la)로 냉동기유가 유입되는 "U"자형 냉동기유 파이프(1)의 중간부에 통공(1b)을 형성하여 냉동기유의 저주파수 소음이 공명실(2)에서 흡수되게 하고, 파이프(1)의 타측의 배출구(1c)에는 공동실(3)에서 흡수되게 구성하였다.Conventional soot relief device forms a through hole (1b) in the middle of the "U" -shaped refrigeration oil pipe (1) into which the refrigeration oil flows into the inlet (la) of one side as shown in (a, b) of FIG. The low frequency noise of the refrigeration oil is absorbed in the resonance chamber 2, and the outlet port 1c on the other side of the pipe 1 is absorbed in the cavity chamber 3.

그러나, 이와같이 구성된 종래의 소옴 경감 장치는 각 부품이 모두 철판으로 제작되어 조립 및 용접이 어렵고, 한 철판은 열전달이 빨라 체적 냉동기유를 가열시키므로 체적 효율이 저하될 뿐만 아니라 하나의 공동실만으로는 고주파수 소옴의 흡수가 미흡하여 소옴이 많이 발생하는 결합이 있었다.However, the conventional SOE reduction device configured as described above is difficult to assemble and weld because each part is made of iron plate, and one iron plate heats up the volume refrigeration oil due to rapid heat transfer, and not only lowers the volume efficiency but also a high frequency source using only one cavity room. There was a lack of absorption, so there were many bonds.

본 고안은 이와같은 종래의 결함을 감안하여 안출한 것으로, 플라스틱을 제작하고, 간단히 조립할 수 있게 함은 물론 2개의 공동실을 형성하여 냉동기유의 고주파수 소음을 효과적으로 경감시킬 수 있게 한 것인바, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised in view of such a conventional defect, and it is possible to manufacture plastics and to easily assemble, as well as to form two cavities to effectively reduce the high-frequency noise of the refrigeration oil, attached to this When described in detail with reference to the drawings as follows.

제2도 내지 제4도에 도시한 바와 같이 내측에 공명실(11)이 형성된 장방헝의 공명실체(10)의 저면에 통공(12)을 형성하고, 공명실체(10)의 주벽(13)의 하부에는 냉동기유가 토출되는 토출구(14)를 형성함과 아울러 주벽(13)의 내측 상부에 단턱(15)를 형성하며, 단탁부(15)에 안착되는 격판(20)의 중앙부에 냉동기유가 유입되는 파이프를(21)를 형성하고, 그 파이프(21)를 상기 통공(12)에 에 고무 재질의 밀봉링(30)을 개재하여 끼움과 아울러 파이프(21)의 중간부에 공명실(11)과 관통되는 통공(22)을 형성하는 한편, 내측에 제1공동실(41)이 형성되어 상기 격판(20)의 상부에 안착되는 공동실체(40)의 상면 일측에 연결관(42)을 형성하고, 연결관(42)과 제1공동실(41) 사이에는 유통공(43)을 형성하며, 연결관(42)의 외주벽 중간부에는 단턱부(44)를 형성하여 소음관(50)이 고무재질의 밀봉링(60)의 개재하에 연결관(42)에 끼워지게 함과 아울러 연결관(42)과 소음관(50)을 접착제(70)로 접착하고, 연결관(42)과 소음관(50)의 사이에는 제2공동실(45)이 형성되게 구성한 것이다.As shown in FIGS. 2 to 4, through holes 12 are formed in the bottom of the resonant chamber 10 having the resonant chamber 11 formed therein, and the circumferential wall 13 of the resonance chamber 10 is formed. The lower portion of the discharge port 14 through which the coolant oil is discharged is formed, and the stepped portion 15 is formed on the inner upper part of the main wall 13, and the coolant oil flows into the central portion of the diaphragm 20 seated on the stepped portion 15. A pipe 21 is formed, and the pipe 21 is inserted into the through hole 12 through a sealing ring 30 made of rubber material, and the resonance chamber 11 is provided at the middle of the pipe 21. While forming a through-hole 22 and a through, the first cavity 41 is formed on the inside to form a connection pipe 42 on one side of the upper surface of the cavity 40 seated on the upper portion of the diaphragm 20. In addition, a distribution hole 43 is formed between the connecting pipe 42 and the first cavity 41, and a step 44 is formed in the middle of the outer circumferential wall of the connecting pipe 42 to form the noise pipe 50. This rubber material The connector pipe 42 and the sound pipe 50 are bonded to each other with the adhesive 70 by being fitted to the connector pipe 42 through the sealing ring 60, and the connector pipe 42 and the sound pipe 50 are interposed therebetween. The second cavity chamber 45 is formed in between.

이와같이 구성된 본 고안은 파이프(21)를 통해 냉동기유가 유입되면, 그 유입된 냉동기유는 파이프(21)를 통해 유입되면서 통공(22)을 통해 공명실(11)로 유입되게 저주파수 소음이 공명실(11)에서 홉수되고, 파이프(21)의 상부로 배출되는 냉동기유는 제1공동실(41)에서 1차로 고주파수 소음이 흡수된 후 유통공(43)을 통해 제2공동실(45) 로 유입되 므로 제1공동실(41)에 서 흡수되지 않고 남아 있는 고주파수 소음이 제2공동실(45)에서 흡수되어 냉동기유의 저주파수 소음은 물론 고주파수 소음이 매우 경감되며, 이때 공명실체(10)의 주벽(13)에 토출구(14)를 형성하여 공명실(11)에 저장된 냉동기유가 토출구(14)를 통해 토출되므로 냉동기유가 공명실(11)의 내부에 저장되어 냉동 효율이 저하되는 것을 방지하게 된다.When the refrigerator oil is introduced through the pipe 21 in this way, the introduced refrigerant oil is introduced into the resonance chamber 11 through the through hole 22 while the introduced refrigerant oil flows through the pipe 21. The refrigeration oil hopped by 11 and discharged to the upper portion of the pipe 21 flows into the second cavity chamber 45 through the distribution hole 43 after the high frequency noise is first absorbed from the first cavity chamber 41. Therefore, the high frequency noise remaining without being absorbed in the first cavity chamber 41 is absorbed in the second cavity chamber 45 so that the low frequency noise of the refrigeration oil as well as the high frequency noise are greatly reduced, and at this time, the circumferential wall of the resonance chamber 10 Since the discharge port 14 is formed in the 13 and the refrigeration oil stored in the resonance chamber 11 is discharged through the discharge port 14, the refrigeration oil is stored in the resonance chamber 11 to prevent the refrigeration efficiency from being lowered.

이상에서와 같이 본 고안은 2개의 공동실을 형성하여 냉동기유의 고주파수 소음을 경감시키므로 종래에 비하여 냉동기유의 고주파수 소음을 월등히 경감시킬 수 있고, 또한 각 부품을 플라스틱으로 제조하며 조립공정의 단순화를 기할 수 있을 뿐만 아니라 공면실의 냉동기유가 토출구(14)로 토출되어 공명실내에 냉동기유가 저장되지 않고 순환되므로 냉동 효율이 저하되는 것을 방지할 수 있는 효과가 있다.As described above, the present invention forms two cavity chambers to reduce the high frequency noise of the refrigeration oil, so that the high frequency noise of the refrigeration oil can be greatly reduced, and each part is made of plastic and the assembly process can be simplified. In addition, since the refrigeration oil of the coplanar chamber is discharged to the discharge port 14 and the refrigeration oil is circulated without being stored in the resonance chamber, there is an effect of preventing the refrigeration efficiency from being lowered.
