본 고안은 밀폐형 압축기의 소음기 오일유입방지구조에 관한 것으로, 특히 흡입소음기 내부에 고여있다가 압축기 외부로 유토출되는 현상을 방지하여, 냉매유동량에 따른 성능저하를 방지하고 흡입소음기 내부체적을 유지하여 소음을 저감하도록 한 밀폐형 압축기의 소음기 오일유입방지구조에 관한 것이다.The present invention relates to a silencer oil inflow prevention structure of a hermetic compressor, in particular, it prevents the phenomenon of leaking into the outside of the compressor after being stuck inside the suction silencer, thereby preventing the performance decrease according to the flow rate of the refrigerant and maintaining the internal volume of the suction silencer. The silencer oil inflow prevention structure of the hermetic compressor to reduce the noise.
종래의 기술에 의한 밀폐형 전동압축기는 제1도에 도시한 바와 같이, 압축기를 보고하고 냉매의 누설을 방지하는 상,하부용기(1)와, 상기 하부용기에 저장되어 있는 냉동기유(12)와, 외부로부터 전원을 전달받는 밀봉단자와, 그 밀봉단자를 통해 인가된 전원을 기계적 에너지로 변환하는 회전자(5) 및 고정자(4)와, 상기 회전자에 끼워 맞춰져 회전하며 하부용기에 고여 있는 냉동기유를 흡상하여 비산하는 크랭크축(6)과, 그 크랭크축의 상단 편심부에 연결된 피스톤(7)과, 그 피스톤의 운동으로 냉매가 흡입되어 압축되고 토출되는 실린더(8)로 구성된다.As shown in FIG. 1, the hermetic electric compressor according to the related art includes an upper and lower container 1 for reporting a compressor and preventing leakage of refrigerant, and a refrigerator oil 12 stored in the lower container. And a sealing terminal which receives power from the outside, a rotor 5 and a stator 4 for converting the power applied through the sealing terminal into mechanical energy, and are rotated by being fitted to the rotor and held in a lower container. It consists of a crankshaft 6 which sucks up and scatters refrigeration oil, a piston 7 connected to the upper eccentric portion of the crankshaft, and a cylinder 8 through which refrigerant is sucked in, compressed and discharged by the movement of the piston.
이와 같이 구성된 장치에 의해 밀봉단자를 통하여 클러스터에 전원이 인가되면 이 전원은 고정자에 인가 된다. 고정자에 인가된 전원에 의해 회전자(5)가 회전하게 되면, 회전자와 함께 끼워 맞춰진 크랭크축(6)이 회전하게 된다. 크랭크 축의 회전에 의해 크랭크 축의 핀부와 연결된 슬라이드가 크랭크 축의 편심에 의해 평행 직선 운동하게 되며, 이 평행 직선 운동으로 슬라이드와 결합된 피스톤이 왕복 운동하고, 이 피스톤(7)의 왕복운동으로 용기 내부에 있는 냉매가 밸브를 통해 실린더(8) 내부로 흡입되고, 또 피스톤에 의해 실린더 내부로 흡입된 냉매가 압축되어 고온 고압의 냉매가 용기 외부로 배출된다. 또한 실린더의 전면에 결합되어 있는 헤드커버 어셈블리(10)는 플라스틱 흡입소음기(11)와 함께 볼트에 의해 체결되어 있다.When power is applied to the cluster through the sealing terminal by the device configured as described above, this power is applied to the stator. When the rotor 5 is rotated by the power applied to the stator, the crankshaft 6 fitted with the rotor rotates. The rotation of the crankshaft causes the slide connected to the pin part of the crankshaft to move in parallel and linear motion due to the eccentricity of the crankshaft. In this parallel linear motion, the piston coupled to the slide reciprocates, and the reciprocating motion of the piston 7 causes The refrigerant is sucked into the cylinder (8) through the valve, and the refrigerant sucked into the cylinder by the piston is compressed to discharge the high temperature and high pressure refrigerant out of the container. In addition, the head cover assembly 10 coupled to the front of the cylinder is fastened by bolts together with the plastic suction silencer 11.
즉 전동기부에 전원이 인가되면 고정자와 회전자의 전기적 작용에 의하여 크랭크 축이 회전하게 되면서, 상부에 결합된 피스톤이 실린더의 내부에서 왕복이동 되면서 통상적인 흡입 및 토출공정을 수행하게 된다. 이때 크랭크축이 회전하면서 밀폐용기 하부에 고여있는 오일을 압축기구부에 비산하게 되는데 이렇게 비산된 오일이 압축기구부만 비산하는 것이 아니라 밀폐용기 상부에 전체적으로 비산하므로 그 오일이 흡입소음기벽면(11)을 타고 밑면에 고여있다가 오일토출구멍(21)으로 흡입소음기 내부에 흡입되어 토출공정에 의해 압축기 외부로 방출하게 된다. 이때, 흡입된 오일이 플라스틱 흡입소음기(11) 내부에 고여 있으면서 성능저하는 시키고 소음저감효과를 방해하게 되는 문제점이 있다.That is, when power is applied to the motor, the crankshaft rotates due to the electrical action of the stator and the rotor, and the piston coupled to the upper portion reciprocates in the cylinder to perform a normal suction and discharge process. At this time, the crankshaft rotates, and oil accumulated in the lower part of the sealed container is scattered in the compression mechanism part. Thus, the oil is scattered in the upper part of the sealed container instead of only the compression part, so that the oil rides on the suction silencer wall surface (11). The oil is discharged into the suction silencer through the oil discharge hole 21 and discharged to the outside of the compressor by the discharge process. At this time, while the sucked oil is accumulated in the plastic suction silencer 11, there is a problem that the performance is reduced and the noise reduction effect is hindered.
따라서, 본 고안의 목적은 상기와 같은 무제점을 해결하기 위해 안출한 것으로, 흡입 소음기 내부에 고여있다가 압축기외부로 유토출되는 현상을 방지하여, 냉매유동량을 증가시켜 성능저하를 방지하고 흡입소음기 내부체적을 유지하여 소음을 저감하도록 한 밀폐형 압축기의 소음기 오일유입방지구조를 제공함에 있다.Accordingly, an object of the present invention is to solve the above-mentioned problems, and to prevent the phenomenon that is stuck inside the suction silencer and flows out to the outside of the compressor, to increase the refrigerant flow rate to prevent the performance degradation and suction silencer It is to provide a silencer oil inflow prevention structure of the hermetic compressor to maintain the internal volume to reduce the noise.
이러한, 본 고안의 목적은 하부에 오일토출구멍을 구비한 흡입소음기의 오일토출구멍 둘레에 오일의 유입을 방지하도록 한 단턱부를 형성함으로써 달성된다.This object of the present invention is achieved by forming a stepped portion to prevent the inflow of oil around the oil discharge hole of the suction silencer having an oil discharge hole at the bottom.
이하, 본 고안에 의한 밀폐형 압축기의 소음기 오일유입방지구조를 첨부도면에 도시한 실시예에 따라서 설명한다.Hereinafter, the silencer oil inflow prevention structure of the hermetic compressor according to the present invention will be described according to the embodiment shown in the accompanying drawings.
제3도는 본 고안에 의한 압축기의 소음기를 나타내는 개략도로서, (가)도는 단면도이고, (나)도는 저면도를 각각 보인 것이다.3 is a schematic view showing a silencer of the compressor according to the present invention, (a) is a cross-sectional view, (b) is a bottom view respectively.
이에 도시한 바와 같이, 본 고안에 의한 밀폐형 전동압축기의 흡입 소음기는 하부에 오일토출구멍(21)을 구비한 흡입소음기의 오일토출구멍(21) 둘레에 오일의 유입을 방지하도록 한 단턱부(31)를 형성한다.As shown in the drawing, the suction silencer of the hermetic electric compressor according to the present invention has a stepped portion 31 which prevents oil from flowing around the oil discharge hole 21 of the suction silencer having the oil discharge hole 21 at the bottom thereof. ).
이와 같이 형성된 본 고안에 의한 밀폐형 압축기의 소음기 오일유입방지구조의 작용효과를 설명하면 다음과 같다.Referring to the effect of the silencer oil inflow prevention structure of the hermetic compressor according to the present invention formed as described above are as follows.
밀폐형 전동압축기의 종래와 동일한 작용은 생략하며, 흡입소음기 구조에서 발생되는 오일유입현상을 방지하기 위해 단형상의 오일가이드인 단턱부(31)를 소음기(11)의 밑면에 설치하여 흡입소음기 벽면을 타고 내려오는 오일이 오일토출구멍(21)으로 흡입되지 못하게 하여 성능저하를 방지하고 흡입소음기 내부체적이 줄어들지 않게 하여 소음저감효과를 극대화하는 구조로 되어 있다.The same operation as that of the conventional hermetic electric compressor is omitted, and in order to prevent oil inflow from the suction silencer structure, the stepped portion 31, which is a short oil guide, is installed on the bottom of the silencer 11 so that the wall of the suction silencer is removed. The oil coming down is not sucked into the oil discharge hole 21 to prevent deterioration of performance and the internal volume of the suction silencer is not reduced to maximize the noise reduction effect.
이상에서 설명한 바와 같이, 본 고안에 의한 밀폐형 전동압축기의 흡입소음기는 하부에 오일토출구멍을 구비한 흡입소음기의 오일토출구멍 둘레에 오일의 유입을 방지하도록 한 단턱부를 형성하여, 흡입소음기 내부에 고여있다가 압축기외부로 유토출되는 현상을 방지하여, 냉매유동량에 따른 성능저하를 방지하고 흡입소음기 내부체적을 유지하여 소음을 저감하도록 한 효과가 있다.As described above, the suction silencer of the hermetic electric compressor according to the present invention forms a stepped portion to prevent oil from flowing around the oil discharge hole of the suction silencer having the oil discharge hole at the bottom thereof, While preventing the flow of oil out of the compressor, it is effective to prevent the performance degradation according to the flow of refrigerant and to reduce the noise by maintaining the internal volume of the suction silencer.
