본 발명은 밀폐형 회전압축기의 소음방지장치, 더욱 상세하게는 밀폐형 회전압축기가 냉매의 흡입ㆍ압축 및 토출작용을 수행하기 위해 실린더의 내부에서 회전하는 구동로울러로 인해 발생되는 소음을 방지할 수 있는 밀폐형 회전압축기의 소음방지장치에 관한 것이다.The present invention is a hermetic anti-noise device of the hermetic rotary compressor, more specifically hermetic rotary compressor is a hermetic type that can prevent the noise generated by the drive roller rotates inside the cylinder to perform the suction, compression and discharge of the refrigerant It relates to a noise preventing device of a rotary compressor.
일반적으로, 공기조화기에 설치된 압축기는 증발기에서 유입되는 저온ㆍ저압의 기체 냉매를 흡입하여 고온ㆍ고압의 기체 냉매로 압축시키는 작용을 한다.In general, a compressor installed in an air conditioner functions to suck low-temperature and low-pressure gas refrigerant flowing from an evaporator and compress it to a high-temperature, high-pressure gas refrigerant.
상기 압축기의 동작에 의해 압축된 냉매는 응축-팽창-증발등의 냉동싸이클을 반복적으로 순환하면서 냉각기를 통과하는 주위의 열을 흡수하고 차거운 공기를 배출하는 소위 열교환작용에 의해 냉방을 하게 된다.The refrigerant compressed by the operation of the compressor is cooled by a so-called heat exchange effect that absorbs the surrounding heat passing through the cooler and discharges the cool air while repeatedly circulating the freezing cycle such as condensation-expansion-evaporation.
이러한 압축기는 냉매를 고압으로 압축하기 위해 비교적 높은 회전속도와 큰 토오크를 요구하게 되므로 이 과정에서 발생된 진동으로 소음이 발생하였다.Since the compressor requires a relatively high rotation speed and a large torque to compress the refrigerant to a high pressure, noise is generated by the vibration generated in this process.
즉, 제1도는 종래의 밀폐형 회전압축기의 측면도이고, 제2도는 종래의 밀폐형 회전압축기의 평면도로서, 밀폐된 압축기의 몸체(1) 내부에 전원공급에 의해 동작되는 전동부(2)가 설치되고, 이 전동부(2)에는 실린더(6)에 축설된 구동축(3)의 일단이 압입되어 있다.That is, FIG. 1 is a side view of a conventional hermetic rotary compressor, and FIG. 2 is a plan view of a conventional hermetic rotary compressor, in which a transmission unit 2 operated by power supply is installed inside the body 1 of the hermetic compressor. One end of the drive shaft 3 built into the cylinder 6 is press-fitted into this transmission part 2.
상기 실린더(6)는 상부플랜지(5)와 하부플랜지(8)에 의해 밀폐되는 실린더실(9)을 구비하고, 이 실린더실(9)에는 상기 구동축(3)의 편심부(3')와 이 편심부(3')에 삽입된 구동로울러(7)가 설치되어 구동축(3)의 중심으로부터 편심되어 회전하면서 실린더(6)의 내주면에 착설된 베인(11)을 출몰시켜 냉매를 흡입 및 압축하고, 압축된 냉매는 상부플랜지(5)에 형성된 토출공(5')과 그 상측의 머플러(4)를 통과하여 몸체의 내부를 순환한 후 외부로 빠져 나간다.The cylinder (6) has a cylinder chamber (9) sealed by an upper flange (5) and a lower flange (8), the cylinder chamber (9) and the eccentric portion (3 ') of the drive shaft (3) and A drive roller 7 inserted into the eccentric portion 3 'is installed, eccentrically rotated from the center of the drive shaft 3, and the vanes 11 mounted on the inner circumferential surface of the cylinder 6 are spouted to suck and compress the refrigerant. The compressed refrigerant passes through the discharge hole 5 'formed in the upper flange 5 and the muffler 4 at the upper side thereof, circulates inside the body, and then exits to the outside.
이때, 상기 구동로울러(7)의 고속회전으로 그의 상하면이 상부플랜지(5)와 하부플랜지(8) 및 실린더(6)의 내측면에 접촉됨에 따라, 실린더의 진동으로 소음이 발생하여 이를 방지하기 위해 압축기의 몸체(1)에 실린더(6)가 고정되도록 용접된 용접부(12)(13)(14)가 형성되어 있었다.At this time, as the upper and lower surfaces of the driving roller 7 are in contact with the inner surface of the upper flange 5 and the lower flange 8 and the cylinder 6, noise is generated by the vibration of the cylinder to prevent this. To this end, welded parts 12, 13 and 14 are formed so that the cylinder 6 is fixed to the body 1 of the compressor.
그러나, 상기 용접부로 상기 실린더를 압축기의 몸체에 고정시켜 소음이 감소되었지만, 연속적인 압축기의 구동으로 용접부가 떨어져 소음이 더 커지는 문제점이 있었다.However, although the noise is reduced by fixing the cylinder to the body of the compressor by the welding part, there is a problem that the noise is greater due to the welding part falling off by the continuous driving of the compressor.
본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로, 압축기의 구동으로 발생되는 실린더의 진동을 완충시켜 소음을 감소시킬 수 있는 밀폐형 회전압축기의 소음방지장치를 제공함을 목적으로 한다.The present invention has been made to solve the conventional problems as described above, it is an object of the present invention to provide a noise preventing device of the hermetic rotary compressor that can reduce the noise by buffering the vibration of the cylinder generated by the drive of the compressor.
이러한 본 발명의 목적은 압축기의 실린더와 압축기 몸체 사이에 완충부를 설치함으로써 달성된다.This object of the present invention is achieved by installing a buffer between the cylinder of the compressor and the compressor body.
상기와 같은 목적을 달성하기 위하여 본 발명은, 구동로울러의 회전으로 그의 외측벽과 마찰하여 진동을 일으키는 실린더의 외측벽과 압축기의 몸체 내측벽 사이에 완충부를 설치하여 소음을 제거함으로써 압축기의 신뢰도가 향상됨을 특징으로 한다.In order to achieve the above object, the present invention, the reliability of the compressor is improved by installing a buffer between the outer wall of the cylinder and the inner wall of the body of the compressor to vibrate friction with its outer wall by the rotation of the drive roller to remove the noise. It features.
이하, 본 발명의 실시예의 밀폐형 회전압축기의 소음방지장치를 첨부된 도면에 의거하여 상세히 설명한다.Hereinafter, the noise prevention device of the hermetic rotary compressor of the embodiment of the present invention will be described in detail with reference to the accompanying drawings.
제3도는 본 발명의 실시예의 밀폐형 회전압축기의 소음방지장치가 설치된 압축기의 평면도로서, 실린더(30)내에 고속으로 회전하는 구동축(50)의 편심부(51)와 편심부(51)에 동심으로 결합된 구동로울러(60)가 회전하도록 설치되고, 상기 실린더(30)가 압축기의 몸체(10)에 고정되도록 용접된 용접부(21)(22)(23)와, 상기 실린더(30)의 진동을 완충하는 완충부(40)(40')가 설치되어 있다.3 is a plan view of a compressor provided with a noise suppression device of the hermetic rotary compressor according to an embodiment of the present invention, which is concentric with the eccentric portion 51 and the eccentric portion 51 of the drive shaft 50 rotating at a high speed in the cylinder 30. The combined driving roller 60 is installed to rotate, welds 21, 22, 23 welded to the cylinder 30 to be fixed to the body 10 of the compressor, and vibration of the cylinder 30. A buffer part 40 (40 ') which buffers is provided.
상기 완충부(40)(40')는 압축기의 몸체(10)의 내측벽과 실린더(30)의 외측면에 서로 맞닫는 제1지지돌기(42)와 제2지지돌기(42')를 형성하고 각각에 완충고무(43)(43')를 씌워서 완충스프링(41)이 끼워진 구조이다.The buffer parts 40 and 40 ′ form a first support protrusion 42 and a second support protrusion 42 ′ which are in contact with each other on the inner wall of the compressor body 10 and the outer surface of the cylinder 30. And the buffer springs 41 are fitted to each of the buffer rubbers 43 and 43 '.
여기에서, 본 발명에 사용된 완충부(40)(40')는 2개이지만 다수개의 완충부를 설치하여도 무방하다.Here, although two buffer parts 40 and 40 'used in the present invention, a plurality of buffer parts may be provided.
