본 고안은 냉장고나 쇼우케이스 또는 냉음료 자판기, 냉동기에 사용되는 소형 왕복동식 압축기에 있어 실린더에 윤활유를 자동 공급시키게 하는 냉장, 냉동기용 왕복동식 압축기의 실린더 오일, 흡입장치에 관한 것으로, 특히 실린더의 피스톤 왕복등에 의해 기내하부에 저장된 오일이 실린더내로 흡입되게 하여 실린더내에 오일이 자동 공급되게 한 것에 있어, 실린더의 헤드 하단을 소정길이로 하향 연장하여 오일수위의 내에 침수되는 흡입구를 일체로 구성하고 이 흡입구와 헤드내에 실린더내로 연통하는 오일 흡입통로를 구성하여 오일이 헤드체로 직접 공급되도록 한 냉장, 냉동기용 왕복동식 압축기의 실린더 오일 흡입장치인 것이다.The present invention relates to a cylinder oil and a suction device of a reciprocating compressor for refrigerating and freezing, which automatically supplies lubricating oil to a cylinder in a small reciprocating compressor used in a refrigerator, a showcase, a cold beverage vending machine, or a freezer. The oil stored in the lower part of the cabin is sucked into the cylinder by the piston reciprocating etc., so that the oil is automatically supplied into the cylinder. The lower end of the cylinder head is extended downward to a predetermined length so that the intake port is submerged in the oil level. It is a cylinder oil suction device of a reciprocating compressor for refrigeration and freezer, in which an oil suction passage communicating with a suction port and a head in a cylinder is configured to supply oil directly to the head.
종래 냉장, 냉동기용 왕복동식 압축기의 실린더 오일 흡입장치를 보면 통상적으로 제1도에서와 같이 실린더(1)의 헤드(2)에, 압축기(3)내 해부에 저장된 오일(4)내에 침수되는 금속재의 흡입파이프(5)를 연설하여 실린더(1)의 피스턴(6) 왕복구동시 발생되는 흡입력에 의해 오일이 흡입파이프(5)를 통하여 실린더 내로 자동 흡입되게 하여서 피스턴의 구동에 윤활을 기하게 하고 있는 것이나, 기기의 가동시 진동 또는 외부의 충격이 가해졌을때 실린더헤드와 금속재의 흡입파이프의 마찰로 소음이 발생되고 흡입파이프가 쉬 파손되는 사례가 발생되었을뿐 아니라 별개의 흡입파이프를 부설하므로서 제작원가가 상승하게 되는 등의 비경제적이고도 제품성이 저하되는 많은 문제점이 있었다.In the conventional cylinder oil suction device of a reciprocating compressor for refrigerating and freezing, a metal material is immersed in the head (2) of the cylinder (1), in the oil (4) stored in the anatomy of the compressor (3) as shown in FIG. The suction pipe (5) is squeezed out so that the oil is automatically sucked into the cylinder through the suction pipe (5) by the suction force generated during the reciprocating operation of the piston (6), thereby lubricating the piston. In addition, when vibration or external shock is applied during operation of the machine, noise is generated by friction between the cylinder head and the metal suction pipe, and the suction pipe is easily broken.It is manufactured by laying a separate suction pipe. There are many problems of uneconomical and deterioration of product quality such as cost increase.
본 고안은 이와같은 문제점을 감안하여 실린더 헤드 하부에 흡입구를 일체로 연장설치하고 헤드체내에 오일 흡입통로를 설치하여 오일이 헤드체내로 직접 흡입공급되게 하여 기기의 가동소음을 방지하고 부품수를 줄이어 제작원가를 절감시키고 오일의 흡입이 원활하도록 안출한것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.In view of the above problems, the present invention extends the inlet port integrally under the cylinder head and installs an oil suction passage in the head body to prevent oil from being directly sucked into the head body to prevent operation noise and reduce the number of parts. Subsequently, the manufacturing cost is reduced and the oil is smoothly sucked out, which will be described in detail with reference to the accompanying drawings.
본 고안은 제1도에서와 같이 통상의 압축기(3)내에 종방향으로 축설되어 회전자(10)가 회동함에 따라 연동되는 크랭크축(8)일단에 피스턴 롯드(6-1)로 하여 피스턴(6)의 왕복구동시 가스를 흡, 배기시키며 피스톤(6)의 흡입력으로 압축기내에 저장된 오일(4)을 실린더(1)내로 흡입하면서 피스턴의 구동에 윤활을 기하게 한것에 있어, 실린더(1)의 헤드(2) 하부에, 압축기(3)내 하부에 저장된 오일(4) 수위내에 침수되는 오일흡입구(2A)를 소정길이로 연장설치하고 이 오일흡입구(2A)와 헤드(2)체 주벽내에, 실린더(1)내로 연통되는 오일흡입통로(2-1)를 구성하여서된 것으로 미설명부호 9는 크랭크축(8)에 오일을 공급시키는 오일흡입콘, 11은 고정자이다.The present invention is constructed as a piston rod 6-1 at one end of a crank shaft 8 interlocked longitudinally in a conventional compressor 3 and interlocked as the rotor 10 rotates as shown in FIG. In the reciprocating operation of 6), the gas is sucked and exhausted and the oil (4) stored in the compressor is sucked into the cylinder (1) by the suction force of the piston (6) to lubricate the driving of the piston. In the lower part of the head 2, the oil suction port 2A submerged in the water level of the oil 4 stored in the lower part of the compressor 3 is extended to a predetermined length, and the oil suction port 2A and the head 2 body main wall , Which constitutes an oil suction passage 2-1 communicating with the cylinder 1, wherein reference numeral 9 denotes an oil suction cone for supplying oil to the crankshaft 8, and 11 denotes a stator.
이와같이 구성된 본 고안의 작동을 설명하면, 본 고안에서 압축기(3)가 가동하게 되면 크랭크축(8)이 회전자(1)에 의해 회동하고, 크랭크축(8)에 연결된 피스턴(6)이 실린더(1)내에 왕복구동되며 가스를 냉동장치로 압송되게 하고 이와동시에 피스턴(6)의 왕복동시 발생되는 흡입력으로 압축기(3)내 하부에 저장된 오일(4)을 실린더(1)내로 흡입되게 하여 피스턴의 구동에 윤활을 기하게한것은 종래와 동일한 방법인것이고 본 고안에서는 실린더(1)의 헤드(2) 하부에 오일(4) 수위내에 침수되는 오일흡입구(2A)와 헤드(2)체내에 걸쳐 실린더(1)내로 연통되는 오일 흡입로(2-1)를 구성하여 피스턴(6)의 구동시 발생되는 흡입력에 의해 오일이 헤드(2) 내를 거쳐 실린더(1)로 직접 흡입공급되게 한 것으로 종래 실린더와 압축기내에 저장된 오일의 사이에 흡입파이프를 연설하여 오일을 흡입파이프를 통하여 흡입공급시킴에 따랐던 가동소음의 문제점을 본 고안에서는 완전배제시키고, 설치부품수를 줄이어 제작원가를 절감시키게되는 경제적인 효과가 있는 동시에 오일의 흡입이 원활하고 따라 실린더내에 윤활유 공급이 정확하여 피스턴의 구동이 안정되고도 원활하여 피스턴의 마모를 최소로 줄이고 압축기의 사용수명을 연장시킬수 있는 등의 제품성을 향상시키게 되는 유용한 고안인 것이다.Referring to the operation of the present invention configured as described above, when the compressor 3 operates in the present invention, the crankshaft 8 is rotated by the rotor 1, and the piston 6 connected to the crankshaft 8 is a cylinder. Reciprocating within (1) and causing the gas to be pumped into the refrigerating device and at the same time the oil (4) stored in the lower part of the compressor (3) to be sucked into the cylinder (1) by the suction force generated during the reciprocation of the piston (6) The lubrication is performed in the same manner as in the prior art. In the present invention, the oil intake port 2A and the head 2 which are submerged in the oil 4 level in the head 2 of the cylinder 1 are submerged. The oil suction passage 2-1 communicating with the cylinder 1 is configured so that the oil is sucked and supplied directly to the cylinder 1 through the head 2 by the suction force generated when the piston 6 is driven. The suction pipe is opened between the cylinder and the oil stored in the compressor. In this design, the problem of the operation noise caused by supplying oil through the suction pipe is completely eliminated, and the economical effect of reducing the manufacturing cost by reducing the number of installation parts, and at the same time, the oil suction is smooth and It is a useful design to improve the productability, such that the supply of lubricating oil in the cylinder is accurate and the piston is stable and smooth, so that the wear of the piston can be minimized and the service life of the compressor can be extended.
