Description

밀폐형 압축기의 소음 저감 구조{STRUCTURE FOR REDUCING NOISE OF HERMETIC COMPRESSOR}Noise reduction structure of hermetic compressor {STRUCTURE FOR REDUCING NOISE OF HERMETIC COMPRESSOR}

본 발명은 밀폐형 압축기의 지지 장치에 관한 것으로서, 특히 압축기 본체를 지지하는 받침부를 복수 개의 곡률로 형성하여 진동을 줄이고자 하는 밀폐형 회전식 압축기의 소음 저감 구조에 관한 것이다.The present invention relates to a support apparatus for a hermetic compressor, and more particularly, to a noise reduction structure of a hermetic rotary compressor which is intended to reduce vibration by forming a plurality of curvatures supporting the main body of the compressor.

알려진 바와 같이 압축기는 유체를 압축하는 기계이다. 이러한 압축기는 동력을 전달하는 전동기구부와 이 전동기구부에 의한 동력을 이용하여 유체를 압축하는 압축기구부로 구성한다. 이 전동기구부와 압축기구부를 한 개의 밀폐 케이싱에 함께 장착하는 것을 밀폐형 압축기라고 한다.As is known, a compressor is a machine that compresses a fluid. Such a compressor is constituted by an electric mechanism portion for transmitting power and a compression mechanism portion for compressing a fluid using power by the electric mechanism portion. Attaching this electric mechanism part and a compressor mechanism part to one hermetic casing is called a hermetic compressor.

밀폐형 압축기는 케이싱의 저면에 삼각받침판을 두어 전동기구부와 압축기구부에서 발생하는 진동이 냉장고나 에어콘으로 전달되는 것을 방지하고 있다.The hermetic compressor has a triangular support plate at the bottom of the casing to prevent vibration generated in the electric mechanism and the compressor mechanism from being transmitted to the refrigerator or the air conditioner.

도 1 및 도 2는 종래 밀폐형 압축기에서 삼각받침판을 분리하여 보인 사시도 및 조립하여 보인 종단면도이다.1 and 2 are a perspective view and a longitudinal cross-sectional view showing the separated triangular support plate in the conventional hermetic compressor.

이에 도시한 바와 같이 종래의 밀폐형 압축기는 그 내부에 동력을 발생하는 전동기구부와 이 전동기구부에 연결하여 유체를 압축하도록 압축기구부를 구비하는 압축기 케이싱(1)과, 압축기 케이싱(1)을 지면으로부터 일정 높이로 떠받쳐 지지하는 삼각받침판(2)으로 이루어져 있다.As shown in the related art, the conventional hermetic compressor includes a compressor casing (1) having a power mechanism that generates power therein, and a compressor casing (1) connected to the power mechanism to compress the fluid, and the compressor casing (1) from the ground. It consists of a triangular support plate (2) to support the support at a certain height.

케이싱(1)은 양단이 개구된 원통형상으로 형성하여 그 내부에 상기한 전동기구부와 압축기구부를 고정 결합하는 케이싱 본체(1a)와, 케이싱 본체(1a)의 상단과 하단을 각각 복개하도록 용접 결합하는 상부캡(1b) 및 하부캡(1c)으로 이루어져 있다.The casing 1 is formed in a cylindrical shape with both ends opened, and is welded to cover the casing main body 1a and the upper and lower ends of the casing main body 1a, respectively. Has an upper cap (1b) and the lower cap (1c).

삼각받침판(2)은 평면투영시 삼각형 평판모양으로 형성하고 그 꼭지점에는 진동을 흡수하기 위한 방진고무(미도시)를 장착하는 방진고무 장착구멍(2a)을 형성하며 그 중앙에는 압축기 케이싱(1)의 하부캡(1c)을 끼워 용접으로 결합하는 케이싱 안착구멍(2b)을 형성하고 있다.The triangular support plate 2 is formed in the shape of a triangular flat plate in planar projection, and at its vertex, an anti-vibration rubber mounting hole 2a is mounted to mount the anti-vibration rubber (not shown) for absorbing vibration, and the compressor casing 1 in the center thereof. The casing seating hole 2b is formed by fitting the lower cap 1c of the casing to be welded.

도면중 미설명 부호인 2c는 용접점이다.2c, which is not described in the drawings, is a welding point.

상기와 같은 종래 밀폐형 압축기에서 진동을 상쇄하는 과정은 다음과 같다.The process of canceling the vibration in the conventional hermetic compressor as described above is as follows.

즉, 압축기 케이싱(1) 내부의 전동기구부에 전원을 연결하면, 그 전동기구부의 가동자가 동작하면서 동력을 압축기구부에 전달하고 이 동력을 전달받은 압축기구부의 피스톤이 왕복 또는 회전운동을 하면서 냉매가스를 흡입 압축하여 토출하는 일련의 과정을 반복한다.That is, when a power source is connected to the electric mechanism part inside the compressor casing 1, the mover of the electric mechanism part operates and transmits power to the compression mechanism part, and the piston of the compression mechanism part which received this power reciprocates or rotates the refrigerant gas. Repeat a series of processes of suction compression and discharge.

이러한 과정에서 진동기구부와 압축기구부에서는 진동이 발생하고 이 진동은 압축기 케이싱(1)으로 전달되어 "웅"하고 울리는 진동소음을 유발한다. 이때, 압축기 케이싱(1)의 하단에는 삼각받침판(2)을 결합하고 그 삼각받침판(2)의 모서리에는 압축기 케이싱(1)을 설치면에서 일정 높이로 지지하는 방지고무(미도시)를 장착하여 상기한 압축기 케이싱(1)의 진동소음을 흡수하면서 상쇄시키는 것이었다.In this process, vibration is generated in the vibrating mechanism part and the compression mechanism part, and the vibration is transmitted to the compressor casing 1 to cause a "hum" and ringing vibration noise. At this time, the lower end of the compressor casing (1) is coupled to the triangular support plate (2) and the anti-rubber (not shown) to support the compressor casing (1) to a certain height from the mounting surface at the corner of the triangular support plate (2) It was made to cancel while absorbing the vibration noise of the compressor casing 1 mentioned above.

그러나, 상기와 같은 종래 밀폐형 압축기에 있어서는, 케이싱(1)의 하부캡(1c)과 삼각받침판(2)이 별개의 부품으로 제작하여 용접으로 후조립함에 따라 하부캡(1c)과 삼각받침판(2) 사이에 사이뜸이 발생하고, 이로 인해 압축기의 구동시 두 부품간 진동과 함께 금속 마찰음을 유발하는 문제점이 있었다.However, in the conventional hermetic compressor as described above, the lower cap 1c and the triangular support plate 2 of the casing 1 are manufactured as separate parts and then assembled by welding, so that the lower cap 1c and the triangular support plate 2 are used. There is a problem between the moxibustion between the two, due to the vibration between the two parts during the operation of the compressor caused a metal friction sound.

본 발명은 상기한 바와 같이 종래의 밀폐형 압축기가 가지는 문제점을 감안하여 안출한 것으로, 케이싱가 삼각받침판 사이에 발생하는 금속 마찰음을 줄일 수 있는 밀폐형 압축기의 소음 저감 구조를 제공하려는데 본 발명의 목적이 있다.The present invention has been made in view of the problems of the conventional hermetic compressor as described above, it is an object of the present invention to provide a noise reduction structure of the hermetic compressor that can reduce the metal friction sound generated between the triangular support plate of the casing.

It protrudes in an annular shape, and the inside of the body seating portion (13b) is formed to be an oil reservoir (13c) for storing the oil to be recessed to a predetermined depth.

받침부(13a)는 편평하게 형성하여 각 꼭지점 부근에는 압축기 케이싱(10)을 설치면에서 일정 높이로 떠받치면서 압축기 진동을 흡수하도록 방진고무를 삽입 고정하기 위한 방진고무장착구멍(13d)을 형성한다.The supporting portion 13a is formed flat to form a dustproof rubber mounting hole 13d for inserting and fixing the dustproof rubber to absorb the compressor vibration while supporting the compressor casing 10 at a predetermined height near each vertex. .

In this case, as the lower cover support plate 13 integrally forms the lower cap and the support plate, it is possible to increase the productivity as well as to increase the reliability as compared to post-assembly of the two members by welding, as well as to reduce the number of assembly due to welding. In addition, since the upper cap 12 and the lower cover support plate 13 can be welded at the same time, there is no need to turn over the casing body 11 during assembly, thereby simplifying the assembly process and increasing the productivity of the product as well as the assembly reliability. have.

또, 하부덮개받침판(13)의 몸체안착부(12)를 2단으로 높게 돌출 형성함에 따라 용접용 토치의 접근과 조작을 용이하게 할 수 있어 조립작업이 용이하고 이로 인해서도 압축기의 생산성을 높일 수 있다.In addition, since the body seating portion 12 of the lower cover support plate 13 is protruded in two stages, the welding and torch can be easily accessed and manipulated, thereby increasing the productivity of the compressor. Can be.

본 발명에 의한 밀폐형 압축기의 소음 저감 구조는, 케이싱 몸체의 하단을 복개하는 하부캡과 이 케이싱 몸체를 지지하는 받침판을 일체로 성형하여 하부덮개받침판을 형성하고 이 하부덮개받침판의 중앙에 복수 개의 곡률을 가지는 오일저장부를 형성함으로써, 부재간 발생하는 금속접촉음을 제거하고 하부덮개받침판의 소음 특성을 개선하여 압축기 소음을 현저하게 줄일 수 있다. 또, 케이싱 몸체를 지지하는 몸체안착부를 2단으로 형성함에 따라 절곡부에서 압축기 진동을 흡수하여 소음을 줄일 수 있다.The noise reduction structure of the hermetic compressor according to the present invention is formed by integrally molding the lower cap covering the lower end of the casing body and the support plate supporting the casing body to form a lower cover support plate, and a plurality of curvatures in the center of the lower cover support plate.
