압축기의 진동전달 방지구조{STRUCTURE FOR PREVENTING VIBRATION TRANSFER IN COMPRESSOR}Vibration transmission prevention structure of compressor {STRUCTURE FOR PREVENTING VIBRATION TRANSFER IN COMPRESSOR}

본 발명은 압축기의 진동전달 방지구조에 관한 것으로, 특히 밀폐용기내에 위치하여 냉매 가스를 압축시키는 전동기구부 및 압축기구부를 밀폐용기내에 지지되도록 결합하는 결합 공정을 간단하게 할 뿐만 아니라 결합 공정 시간을 감소시킬 수 있도록 한 압축기의 진동전달 방지구조에 관한 것이다.The present invention relates to an anti-vibration structure of the compressor, and in particular, the coupling process for coupling the electric mechanism part and the compressor mechanism part which are located in the sealed container to compress the refrigerant gas to be supported in the sealed container as well as reducing the coupling process time. It relates to a vibration transmission preventing structure of a compressor to be made.

일반적으로 냉동사이클장치를 구성하는 압축기는 증발기에서 유입되는 냉매를 압축시켜 고온고압의 상태로 토출시키는 기기이다.In general, the compressor constituting the refrigeration cycle device is a device for compressing the refrigerant flowing from the evaporator to discharge the high temperature and high pressure.

상기 압축기는 소정의 내부 공간을 갖는 밀폐된 밀폐용기와, 상기 밀폐용기내에 장착되어 구동력을 발생시키는 전동기구부와, 상기 전동기구부의 구동력을 전달받아 냉매 가스를 압축하는 압축기구부를 포함하여 구성된다. 상기 압축기는 전원이 인가되어 전동기구부에서 구동력을 발생시키게 되면 그 구동력을 전달받아 압축기구부에서 냉매 가스를 흡입하고 압축하여 토출시키게 된다.The compressor includes a hermetically sealed container having a predetermined internal space, an electric mechanism part mounted in the hermetic container to generate a driving force, and a compressor mechanism part compressing the refrigerant gas by receiving the driving force of the electric mechanism part. When the power source is applied to generate a driving force in the electric mechanism unit, the compressor receives the driving force to suck, compress and discharge the refrigerant gas in the compression mechanism unit.

이와 같이 냉매 가스를 흡입하고 압축하여 토출시키는 과정을 반복적으로 지속하는 과정에서 진동 소음이 발생하게 되며 그 진동 소음이 밀폐용기로 전달되어 외부로 파장되어 나가게 되면 매우 불쾌한 느낌을 주게 될 뿐만 아니라 부품의 결합 상태를 불량하게 만들게 된다. 이와 같이 냉매 가스를 흡입/압축하고 토출시키는 과정에서 전동기구부와 압축기구부에서 발생되는 진동 소음이 밀폐용기로 전달되는 것을 최소화하기 위하여 전동기구부와 압축기구부가 완충부재인 스프링에 의해 지지된다.As such, vibration noise is generated in the process of repeatedly inhaling, compressing, and discharging the refrigerant gas, and when the vibration noise is transmitted to the airtight container and waved to the outside, a very unpleasant feeling is caused. This will lead to poor coupling. In this way, in order to minimize the transmission of vibration noise generated in the power mechanism and the compressor mechanism to the sealed container during the suction / compression and discharge of the refrigerant gas is supported by a spring that is a shock absorbing member.

도 1a, 1b는 상기 압축기를 구성하는 밀폐용기(10)와 그 밀폐용기(10)의 내부에 설치되는 전동기구부와 압축기구부를 하나의 질량체(20)로 하여 도시하고, 상기 질량체(20)가 완충부재인 스프링에 의해 밀폐용기(10)내에 지지되는 상태를 도시한 것이다.1A and 1B show the hermetic container 10 constituting the compressor, and the electric mechanism part and the compression mechanism portion provided in the hermetic container 10 as one mass body 20, the mass body 20 being The state supported in the closed container 10 by the spring which is a shock absorbing member is shown.

도 1a, 1b에 도시한 바와 같이, 종래 압축기에서 질량체(20)에서 발생되는 진동이 밀폐용기(10)로 전달되는 것을 감소시키기 위한 구조는 상기 질량체(20)의 일측에 다수개의 질량체측 결합부(21)가 형성되고, 상기 밀폐용기(10)의 저면에 상기 질량체측 결합부(21)와 상응하도록 다수개의 용기측 결합부(11)가 형성되어 있다. 그리고 상기 질량체측 결합부(21)와 용기측 결합부(11)사이에 소정의 길이를 갖는 코일 스프링(30)이 각각 삽입된다. 상기 질량체측 결합부(21) 및 용기측 결합부(11)는 소정의 외경과 길이를 갖도록 돌출 형성되며 그 돌출 형성된 질량체측 결합부(21)와 용기측 결합부(11)에 코일 스프링(30)의 양단이 각각 끼워져 결합된다. 상기 질량측 결합부(21)와 용기측 결합부(11)는 보통 4개 형성된다.As shown in Figure 1a, 1b, the structure for reducing the transmission of vibration generated in the mass 20 in the conventional container in the closed container 10 in the conventional compressor has a plurality of mass-side coupling portion on one side of the mass 20 21 is formed, and a plurality of container side coupling portions 11 are formed on the bottom surface of the sealed container 10 so as to correspond to the mass side coupling portions 21. A coil spring 30 having a predetermined length is inserted between the mass body side coupling portion 21 and the container side coupling portion 11, respectively. The mass body side coupling portion 21 and the container side coupling portion 11 are protruded to have a predetermined outer diameter and length, and the coil spring 30 is formed on the protruding mass body side coupling portion 21 and the container side coupling portion 11. Both ends of the) are fitted to each other. The mass side engaging portion 21 and the container side engaging portion 11 are usually formed four.

상기한 바와 같은 구조는 전동기구부와 압축기구부를 포함하여 이루어진 질량체(20)에서 냉매 가스를 흡입하고 압축하여 토출시키는 과정에서 질량체(20)에서 발생되는 진동이 코일 스프링(30)에 의해 완충되어 밀폐용기(10)로 전달되는 것이 최소화됨으로써 밀폐용기(10) 외부로 진동 소음이 발생되는 것이 억제된다.As described above, the vibration generated in the mass body 20 is absorbed and sealed by the coil spring 30 in the process of sucking, compressing, and discharging the refrigerant gas from the mass body 20 including the electric mechanism part and the compression mechanism part. By minimizing the transmission to the container 10, the generation of vibration noise outside the sealed container 10 is suppressed.

그러나 상기한 바와 같은 종래의 구조는 밀폐용기(10)내에 위치하는 전동기구부 및 압축기구부를 포함하여 구성되는 질량체(20)가 밀폐용기(10)내에 지지되도록 하여 냉매 가스를 압축시 질량체(20)에서 발생되는 진동이 밀폐용기(10)로 전달되는 것을 최소화시키는 다수개의 코일 스프링(30)을 질량체(20)와 밀폐용기(10)에 결합시 다수개의 코일 스프링(30)을 각각 낱개로 결합하여야 되므로 조립 공정수가 많아지게 될 뿐만 아니라 조립 시간이 많이 소요되는 문제점이 있었다.However, in the conventional structure as described above, the mass body 20 including the electric mechanism part and the compression mechanism part located in the hermetic container 10 is supported in the hermetic container 10 to compress the refrigerant gas. When the plurality of coil springs 30 to minimize the vibration generated in the sealed container 10 to the mass body 20 and the sealed container 10 must be coupled to each of the plurality of coil springs 30 individually. As a result, the number of assembly processes increases, as well as the assembly takes a lot of time.

상기한 바와 같은 문제점을 감안하여 안출한 본 발명의 목적은 밀폐용기내에 위치하여 냉매 가스를 압축시키는 전동기구부 및 압축기구부를 밀폐용기내에 지지되도록 결합하는 결합 공정을 간단하게 할 뿐만 아니라 결합 공정시간을 감소시킬 수 있도록 한 압축기의 진동전달 방지구조를 제공함에 있다.The object of the present invention devised in view of the above problems is to simplify the coupling process as well as the coupling process for coupling the electric mechanism part and the compressor mechanism to be supported in the hermetic container located in the hermetic container to compress the refrigerant gas.
