본 고안은 밀폐형 회전식 압축기에 관한 것으로, 특히 머플러와 하베어링 사이에 다수의 공간부를 형성하여 압축기에서 발생되는 소음이 상기 공간부를 통과하면서 저감되도록 한 밀폐형 회전식 압축기의 소음저감장치에 관한 것이다.The present invention relates to a hermetic rotary compressor, and more particularly, to a noise reduction device of a hermetic rotary compressor in which a plurality of spaces are formed between a muffler and a lower bearing to reduce noise generated in the compressor while passing through the spaces.
일반적인 밀폐형 회전식 압축기는 제1도에 도시한 압축기의 종단면도에서 보는 바와같이, 밀폐용기(1) 내부에 전동부인 고정자(2) 및 회전자(3)가 설치되고, 상기 회전자(3)의 내경에 크랭크축(4)이 압입고정되어 있으며, 상기 크랭크축(4)의 하부에는 상, 하베어링(5)(6)에 나사(7)로 결합되어 있는 실린더(8)와, 상기 실린더(8)의 내경을 접하면서 회전하는 로울러(9)와, 상기 로울러(9)와 접촉되면서 압축공간을 형성하는 베인(미도시)으로 구성되는 압축기 구부가 형성되어 있고, 상기 하베어링(6)에는 머플러(10)가 복개고정되어 있다.In the general hermetic rotary compressor, as shown in the longitudinal cross-sectional view of the compressor shown in FIG. 1, the stator 2 and the rotor 3, which are electric parts, are installed inside the hermetic container 1, and the rotor 3 is The crankshaft 4 is press-fitted and fixed to an inner diameter, and a cylinder 8 coupled to the upper and lower bearings 5 and 6 with a screw 7 at the lower portion of the crankshaft 4 and the cylinder ( The compressor 9 is formed by a roller 9 rotating while contacting the inner diameter of 8), and a vane (not shown) contacting the roller 9 to form a compression space, and the lower bearing 6 is formed. The muffler 10 is fixed to the stomach.
상기 밀폐용기(1)의 외측에는 냉매를 저장하는 흡입탱크(11)가 연결설치되어 있고, 밀폐용기(1)의 상단부에는 외부 전원을 공급하여 고정자(2)에 연결시키는 밀봉단자(12)가 설치되어 있으며, 압축된 가스가 토출되는 토출파이프(13)가 설치되어 있다.The suction tank 11 for storing the refrigerant is connected to the outside of the sealed container 1, the upper end of the sealed container 1 is sealed terminal 12 for supplying external power to connect to the stator (2) A discharge pipe 13 through which compressed gas is discharged is provided.
미설명 부호 0는 오일을 나타낸 것이다.Reference numeral 0 indicates oil.
이와 같이 구성되는 밀폐형 회전식 압축기는 고정자(2)와 회전자(3)의 유도기전력에 의해 회전자(3)와 크랭크축(4)이 편심회전을하게 되면, 크랭크축(4)의 편심축에 조립된 로울러(9)가 실린더(8)의 내경을 따라 회전되어 흡입탱크(11)로부터 유입된 가스가 로울러(9)의 회전에 따라 압축되고, 압축된 가스는 로울러(9)와 접촉되어 있는 베인의 상, 운동에 의해 저압측과 고압측으로 분리된다.In the hermetic rotary compressor configured as described above, when the rotor 3 and the crankshaft 4 are eccentrically rotated by the induction electromotive force of the stator 2 and the rotor 3, the eccentric shaft of the crankshaft 4 is formed. The assembled roller 9 is rotated along the inner diameter of the cylinder 8 so that the gas introduced from the suction tank 11 is compressed by the rotation of the roller 9, and the compressed gas is in contact with the roller 9. The vane is separated into the low pressure side and the high pressure side by the phase and motion.
이처럼, 저압측에서 고압측으로 압축된 가스는 실린더(8)와 고정체결되어 있는 상, 하베어링(5)(6)의 토출공으로 토출되는 것으로, 이때 제2도 및 제4도에 나타낸 바와 같이, 상기 하베어링(6)에 고정 체결되어 있는 밸브 및 리테이너(14)는 압축된 가스가 일정시점에서 연속적으로 토출될 수 있도록 상,하운동을 하게 되며, 상기실린더(8)의 고압측에서 빠져 나온 가스는 하베어링(6)에 고정되어 있는 머플러(10)쪽으로 토출되어 머플러(10) 내부에 형성되어 있는 공간을 통과하면서 일정정도 소음이 저감된 후, 다시 하베어링(6)의 가스공(6a)를 통과하고 실린더(8)와 상베어링(5)의 구멍을 따라 고정자(2) 쪽으로 유입되어 밀폐용기(1)의 상단부에 설치되어 있는 토출파이프(13)를 통해 외부로 토출되는 것이다.As such, the gas compressed from the low pressure side to the high pressure side is discharged to the discharge holes of the lower bearings 5 and 6, which are fixedly fastened to the cylinder 8, as shown in FIG. 2 and FIG. The valve and retainer 14 fixedly fastened to the lower bearing 6 are moved up and down so that the compressed gas can be continuously discharged at a predetermined time point, and exited from the high pressure side of the cylinder 8. The gas is discharged toward the muffler 10 fixed to the lower bearing 6 to pass through the space formed inside the muffler 10 and the noise is reduced to some extent, and then the gas hole 6a of the lower bearing 6 is again present. ) And flows into the stator 2 along the holes of the cylinder 8 and the upper bearing 5 to be discharged to the outside through the discharge pipe 13 installed at the upper end of the sealed container 1.
그러나, 종래에는 소음을 저감하기 위한 머플러의 형상을 복잡하게 구성하거나, 머플러의 내부의 공간을 다수개로 분할하여 형성하기 어렵기 때문에 가스의 유동으로 인해 발생되는 소음의 전달손실을 기대하기 어려운 구조였다. 즉, 도면에서와 같이, 머플러(10)가 일반적으로 2개의 대칭적 구조인 공간으로 분할, 구성되어 있어 소음의 전달손실이 크지 않으므로 압축기의 소음이 증대되는 문제점이 있었다.However, in the related art, it is difficult to expect a transmission loss of noise generated by the flow of gas because it is difficult to form a muffler for reducing noise or to divide and form a plurality of spaces inside the muffler. . In other words, as shown in the figure, the muffler 10 is generally divided into two symmetrical structures, and thus there is a problem in that the noise of the compressor is increased because the transmission loss of the noise is not large.
이러한 문제점을 감안하여 안출한 본 고안의 목적은 머풀러와 하베어링의 사이에 다수의 공간을 갖는 칸막이부를 형성하여 압축기에서 발생되는 소음이 상기 칸막이부를 통과하면서 저감되도록 하려는 데 있다.The object of the present invention devised in view of these problems is to form a partition portion having a plurality of spaces between the muffler and the lower bearing so that the noise generated in the compressor is reduced while passing through the partition portion.
상기한 바와 같은 본 고안의 목적을 달성하기 위하여, 하베어링과 머플러 사이에 다수의 공간을 갖는 칸막이부를 형성하여서 됨을 특징으로 하는 밀폐형 회전식 압축기의 소음저감장치가 제공된다.In order to achieve the object of the present invention as described above, there is provided a noise reduction device of a hermetic rotary compressor, characterized in that forming a partition portion having a plurality of spaces between the bearing and the muffler.
이하, 상기한 바와 같은 본 고안을 첨부도면에 도시한 일실시레에 의거하여 보다 상세히 설명한다.Hereinafter, the present invention as described above will be described in more detail on the basis of one embodiment shown in the accompanying drawings.
제5도 내지 제7도는 본 고안에 의한 베어링과 머플러의 체결상태를 도시한 것으로, 제5도는 분해사시도, 제6도는 머플러를 제거한 상태에서의 평면도, 제7도는 머플러를 체결한 상태에서의 제6도의 B-B선 단면도로서, 이에 도시한 바와 같이, 본 고안 밀폐형 회전식 압축기의 소음저감장치는 하베어링(6)과 상기 하베어링(6)에 복개되는 머플러(10) 사이에 다수의 공간을 갖는 칸막이부(20)를 형성하여서 된 것을 특징으로 한다.5 to 7 show the coupling state between the bearing and the muffler according to the present invention, FIG. 5 is an exploded perspective view, FIG. 6 is a plan view in a state where the muffler is removed, and FIG. 6B is a cross-sectional view taken along line BB, in which the noise reduction device of the hermetic rotary compressor includes a partition having a plurality of spaces between the lower bearing 6 and the muffler 10 covered by the lower bearing 6. Characterized in that the portion 20 is formed.
상기한 바와 같이 하베어링(6)의 상측에 다수개의 공간을 갖는 칸막이부(20)를 형성함으로써, 머플러(10)에 직접 복잡한 공간부 구성을 위한 형상을 만들지 않고도 하베어링(6)의 상면에 다수의 공간이 형성된 상태에서 머플러(10)가 하베어링(6)과 결합되기 때문에, 압축된 토출가스가 상기 칸막이부(20)에 의해서 형성된 각각의 공간을 통과하게 됨으로써 소음의 전달손실이 증대되어 전체 압축기의 소음이 현저하게 저감되는 것이다.By forming the partition portion 20 having a plurality of spaces on the upper side of the lower bearing 6 as described above, the upper surface of the lower bearing 6 can be formed without forming a shape for the complicated space portion configuration directly on the muffler 10. Since the muffler 10 is coupled to the lower bearing 6 in a state where a plurality of spaces are formed, the compressed discharge gas passes through each space formed by the partition portion 20, thereby increasing the transmission loss of noise. The noise of the entire compressor is significantly reduced.
제8도는 단순확장형 머플러의 구조를 기하학적으로 도시한 것으로, (a)는 종래의 머플러 구조, (b)는 본 고안의 머플러 구조를 나타내 보인 것이다.8 illustrates a structure of a simple expandable muffler geometrically, (a) shows a conventional muffler structure, and (b) shows a muffler structure of the present invention.
이상에서 설명한 바와 같이, 본 고안이 적용된 밀폐형 회전식 압축기는 머플러와 하베어링 사이에 다수의 공간을 갖는 칸막이부가 형성되어 있어 소음의 전달손실이 증대됨으로써 압축기에서 발생되는 소음이 현저하게 저감되는 효과가 있다.As described above, the sealed rotary compressor to which the present invention is applied has a partition portion having a plurality of spaces between the muffler and the lower bearing, so that the noise generated in the compressor is significantly reduced by increasing the transmission loss of the noise. .
