본 고안은 밀폐형 전동압축기에 관한 것으로, 특히 냉동기유의 흡상시 함께 흡상되는 오물이 냉동기유로 재유입되거나, 각 기구부로 침투되는 것을 방지하도록 한 밀폐형 전동압축기의 오물수거장치에 관한 것이다.The present invention relates to a hermetic electric compressor, and more particularly, to a sewage collecting device of a hermetic electric compressor that prevents dirt that is sucked up together with the suction of the refrigerant oil from being re-introduced into the refrigerant oil or penetrated into each mechanism.
일반적인 밀폐형 전동압축기는 제1도에 도시한 바와 같이, 상하부용기(1)(2)내에 프레임(3)이 설치되어 있고, 상기 프레임(3)의 중앙에는 크랭크샤프트(4)가 설치되어 있으며, 상기 크랭크샤프트(4)에는 회전자(5)가 압입고정되어 있고, 상기 프레임(3)에는 고정자(6)가 설치되어 전동기구부를 이루고 있다.As a general hermetic electric compressor, as shown in FIG. 1, a frame 3 is provided in the upper and lower containers 1 and 2, and a crank shaft 4 is provided in the center of the frame 3, A rotor 5 is press-fitted to the crankshaft 4, and a stator 6 is provided to the frame 3 to form an electric mechanism part.
또한, 상기 크랭크샤프트(4)의 상부에는 실린더(7)가 설치되며, 이 실린더(7)의 내부에는 상기 크랭크샤프트(4)의 회전에 의해 왕복운동하는 피스톤(8)이 설치되어 일측에 형성된 흡토출부(9)를 통해 냉매를 흡입, 토출하는 압축기구부를 구성하고 있다.In addition, a cylinder 7 is installed at an upper portion of the crankshaft 4, and a piston 8 reciprocating by the rotation of the crankshaft 4 is installed inside the cylinder 7 and formed at one side. A compressor mechanism for suctioning and discharging the refrigerant through the suction discharge unit 9 is configured.
상기 10은 밀봉단자, 11은 클러스터, 12는 흡입파이프를 나타낸 것이다.10 is a sealing terminal, 11 is a cluster, 12 is a suction pipe.
이와 같이 구성된 밀폐형 전동압축기에 전원이 인가되면, 상기 밀봉단자(10)를 통해 동력이 공급되어 밀봉단자(10)와 연결된 클러스터(11)를 통해 고정자(6)에 전원이 공급되면, 회전자(5)가 회전되어 회전자(5)와 결합되어 있는 크랭크샤프트(4)가 회전되어 크랭크샤프트(4)의 상부에 설치되는 피스톤(8)이 왕복운동되어 헤드와 밸브에 의해 압축기 내부의 냉매가 실린더(7)의 내부의 압축실로 흡입되고, 흡입된 냉매는 피스톤(8)에 의해 압축되어 배출된다. 이러한 과정에서 상기 크랭크샤프트(4)의 회전에 의해 용기의 하부에 수납되어 있는 냉동기유가 크랭크샤프트(4)의 상부로 흡상되어 각 기구부에 비산되어 냉각과 윤활작용을 하게 된다.When power is applied to the hermetic electric compressor configured as described above, power is supplied through the sealing terminal 10 and power is supplied to the stator 6 through the cluster 11 connected to the sealing terminal 10. 5) The crankshaft 4 coupled with the rotor 5 is rotated so that the piston 8 installed on the top of the crankshaft 4 reciprocates so that the refrigerant inside the compressor is moved by the head and the valve. It is sucked into the compression chamber inside the cylinder 7, and the sucked refrigerant is compressed by the piston 8 and discharged. In this process, the refrigeration oil contained in the lower part of the container is sucked up to the upper part of the crankshaft 4 by the rotation of the crankshaft 4 to be scattered to each mechanism part to perform cooling and lubrication.
그런데, 상기한 바와 같은 냉동기유의 냉각 및 윤활작용중에 크랭크샤프트(4)에 의해 흡상되는 냉동기유와 함께 압축기 내부에 있는 오물이 흡상되어 일부는 크랭크샤프트(4)의 탄부에서 냉동기유와 함께 비산되어 각 기구부로 침투되고, 일부는 제3도의 A부로 크랭크샤프트(4)의 원심력에 의해 오물이 쌓이게 되며, 제4도에서 나타난 것처럼, 홈(100a)을 통해 B부에 쌓이게 되는데, A부에 쌓인 오물은 크랭크샤프트(4) 정지시 다시 흘러내려 냉동기유와 혼합되어 재작동시 오물이 재흡상되는 문제가 있었고, B부에 쌓인 오물은 홈(100a)이 오물의 상단에 위치하므로 재기 동시에 다시 흡상되어 각 기구부로 전달되어 기구부에 마모가 발생되는 문제가 있었다.By the way, during the cooling and lubrication of the refrigeration oil as described above, the dirt inside the compressor is sucked up together with the refrigeration oil sucked up by the crankshaft (4), and a part of it is scattered together with the freezer oil in the burnt part of the crankshaft (4). It penetrates into each mechanism part, and part of it accumulates in the part A of FIG. 3 by centrifugal force of the crankshaft 4, and as shown in FIG. 4, it accumulates in the part B through the groove 100a. The dirt flowed down again when the crankshaft (4) stopped and mixed with the refrigeration oil, so that the dirt was re-sucked when restarting. There was a problem that the wear to the mechanism portion is delivered to each mechanism portion.
이와 같은 문제점을 감안하여 안출한 본 고안의 목적은 냉동기유와 함께 흡상되는 오물을 별도의 오물저장홈에 수거토록 하여 크랭크샤프트의 정지시에 오물이 낙하하여 오일과 재혼입되는 것을 방지하려는데 있다.The object of the present invention devised in view of the above problems is to collect the dirt sucked with the refrigeration oil in a separate dirt storage groove to prevent the dirt from falling down and remixing with the oil when the crankshaft is stopped.
이러한 본 고안의 목적을 달성하기 위하여, 크랭크샤프트의 하단부에 형성되어 흡상되는 오물이 유입되는 오물배출구와, 상기 크랭크샤프트의 외측 상방향으로 형성되어 상기 오물배출구로 유입되는 오물이 수거되는 오물저장홈과, 상기 오물배출구와 오물저장홈을 연결하는 연결홈으로 구성한 것을 특징으로 하는 밀폐형 전동압축기의 오물수거장치가 제공된다.In order to achieve the object of the present invention, the waste discharge port is formed in the lower end of the crankshaft is introduced into the waste discharge, and the waste storage groove is formed in the upper direction of the crankshaft is collected in the waste discharge outlet And, there is provided a waste collection device of the hermetic electric compressor comprising a connection groove for connecting the waste outlet and the waste storage groove.
이하, 상기한 바와 같은 본 고안을 첨부도면에 도시한 일실시예에 의거하여 보다 상세히 설명한다.Hereinafter, the present invention as described above will be described in more detail based on one embodiment shown in the accompanying drawings.
첨부도면 제5도는 본 고안에 의한 밀폐형 전동압축기의 오물수거장치를 보인 크랭크샤프트의 확대단면도로서, 이에 도시한 바와 같이, 본 고안 장치는 크랭크샤프트(4)에 오물배출구(100b)를 형성하고, 상기 오물배출구(100b)의 상방향으로 크랭크샤프트(4)의 외측에 오물저장홈(102)을 형성하며, 상기 오물배출구(100b)와 오물저장홈(102)을 연결하는 연결홈(101a)을 형성한 것이다.5 is an enlarged cross-sectional view of the crankshaft showing the waste collection device of the hermetic electric compressor according to the present invention. As shown in the drawing, the present invention provides a waste discharge outlet 100b on the crankshaft 4, Forming a waste storage groove 102 on the outer side of the crankshaft 4 in the upward direction of the waste discharge port (100b), the connection groove 101a for connecting the waste discharge port (100b) and the waste storage groove (102) It is formed.
상기 오물저장홈(102)은 상기 연결홈(101a)의 최상점보다 낮게 형성되어 있다.The dirt storage groove 102 is formed lower than the highest point of the connection groove (101a).
이와 같이 구성되어 있는 본 고안 장치는 압축기에 전원이 인가되면, 크랭크샤프트(4)가 회전되어 냉동기유가 원심력에 의해 흡상될 때, 냉동기유와 함께 흡상되는 오물이 오물배출구(100b)를 통해 연결홈(101a)을 지나 오물저장홈(102)에 모이게 되며, 이와 같이 오물저장홈(102)에 모인 오물은 크랭크샤프트(4)가 정지되더라도 다시 냉동기유로 흘러내리지 않게 되는 것이다.When the power supply is applied to the compressor, the inventive device configured as described above, when the crankshaft 4 is rotated and the coolant oil is sucked up by centrifugal force, the dirt sucked up with the freezer oil is connected through the waste discharge port 100b. The waste is collected in the waste storage groove 102 through (101a), so that the waste collected in the waste storage groove 102 will not flow back into the freezer oil even if the crankshaft (4) is stopped.
한편, 제6도에 도시한 바와 같이, 크랭크샤프트의 단차부(13)위에 아래에 오물배출구(100c)를 형성하고, 상기 오물배출구(100c)와 단차부(13)가 연결홈(101b)으로 연결된 본 고안의 다른 실시예를 제공한다.Meanwhile, as shown in FIG. 6, a dirt discharge port 100c is formed below the step portion 13 of the crankshaft, and the dirt discharge port 100c and the step portion 13 are connected to the connection groove 101b. Another embodiment of the present invention is provided that is connected.
이러한 실시예는 크랭크샤프트(4)가 회전되면, 오물배출구(100c)를 통해서 오물이 유입되어 연결홈(101b)을 지나 단차부(13)의 C부로 오물이 모이게 되는 것이다.In this embodiment, when the crankshaft (4) is rotated, the dirt is introduced through the waste discharge port (100c) is collected through the connection groove 101b to the C portion of the step portion (13).
이상에서 설명한 바와 같이, 본 고안에 의한 밀폐형 전동압축기의 오물수거장치는 냉동기유와 함께 흡상되어 다시 냉동기유로 재유입되거나, 각 기구부로 침투되는 오물을 수거하여 기기의 성능 및 신뢰도를 향상시킨 것이다.As described above, the waste collection device of the hermetic electric compressor according to the present invention is sucked together with the refrigeration oil and reintroduced into the refrigeration oil, or collects the dirt penetrated into each mechanism part to improve the performance and reliability of the device.
