Description

밀폐형 회전 압축기{HERMETIC ROTARY COMPRESSOR}Hermetic rotary compressor {HERMETIC ROTARY COMPRESSOR}

본 발명은, 밀폐형 회전 압축기에 관한 것으로서, 보다 상세하게는, 부품의 마모를 방지할 수 있으며 케이싱내에 실린더를 용이하게 삽입할 수 있도록 한 밀폐형 회전 압축기에 관한 것이다.TECHNICAL FIELD The present invention relates to a hermetic rotary compressor, and more particularly, to a hermetic rotary compressor which can prevent abrasion of parts and easily insert a cylinder into a casing.

일반적으로 밀폐형 회전 압축기는, 내부에 밀폐된 수용공간을 형성하는 케이싱과, 케이싱의 내부에 수용되어 압축공간을 형성하는 실린더와, 실린더의 내부에 편심운동 가능하게 수용되어 냉매를 압축하는 롤러와, 롤러에 구동력을 제공하는 전동모터부를 가진다.In general, the hermetic rotary compressor includes a casing for forming an enclosed receiving space therein, a cylinder accommodated in the casing for forming a compression space, a roller for eccentric movement in the cylinder to compress the refrigerant, It has an electric motor part for providing a driving force to the roller.

도 1은 종래의 밀폐형 회전 압축기의 실린더의 평면도이고, 도 2는 도 1의 실린더의 설치상태의 부분확대 단면도이다. 이들 도면에 도시된 바와 같이, 실린더(111)의 내부에는 회전축(121)의 편심부(122)에 일체로 회전가능하게 결합된 롤러(123)가 편심되게 수용되어 내경면을 따라 회전하며 냉매를 압축하는 압축공간(S)이 형성되어 있으며, 압축공간(S)의 일측에는 외부로부터 냉매를 흡입할 수 있도록 반경방향을 따라 흡입구(112)가 관통형성되어 있다.1 is a plan view of a cylinder of a conventional hermetic rotary compressor, and FIG. 2 is a partially enlarged cross-sectional view of an installation state of the cylinder of FIG. 1. As shown in these drawings, the roller 123, which is integrally rotatably coupled to the eccentric portion 122 of the rotating shaft 121, is eccentrically accommodated in the cylinder 111 to rotate along the inner diameter surface and cool the refrigerant. A compression space S for compression is formed, and one side of the compression space S has a suction port 112 formed therethrough in a radial direction so as to suck the refrigerant from the outside.

압축공간(S)의 둘레방향을 따라 흡입구(112)의 일측에는 압축된 냉매가 토출될 수 있도록 토출포트(114)가 형성되어 있으며, 토출포트(114)와 흡입구(112)의 사이영역에는 롤러(123)의 외경에 접촉되어 압축공간(S)을 흡입영역과 토출영역으로 구획하는 베인(125)을 수용할 수 있도록 압축공간(S)과 상호 연통되고 반경방향을 따라 연장되게 베인수용부(116)가 형성되어 있다.A discharge port 114 is formed at one side of the suction port 112 along the circumferential direction of the compression space S so that the compressed refrigerant can be discharged, and a roller is formed at an area between the discharge port 114 and the suction port 112. The vane receiving portion communicates with the compression space S and extends along the radial direction so as to be in contact with the outer diameter of the 123 to accommodate the vanes 125 that divide the compression space S into the suction area and the discharge area. 116 is formed.

압축공간(S)의 반경방향을 따라 베인수용부(116)의 일측에는 베인(125)이 롤러(123)의 외경에 탄성적으로 접촉될 수 있게 베인(125)의 후방에서 베인(125)을 탄성지지하는 스프링부재(120)를 수용할 수 있도록 스프링수용부(118)가 형성되어 있다.In one side of the vane accommodating portion 116 along the radial direction of the compression space S, the vanes 125 are disposed at the rear of the vanes 125 so that the vanes 125 may elastically contact the outer diameter of the roller 123. A spring accommodating part 118 is formed to accommodate the spring member 120 that is elastically supported.

그런데, 이러한 종래의 밀폐형 회전 압축기에 있어서는, 스프링수용부(118)의 내부에 수용된 스프링부재(120)가 실린더(111)의 외측으로 돌출된 상태에서 실린더(111)가 케이싱(110)의 내부에 수용결합되도록 하고 있어, 실린더(111)의 삽입시 스프링부재(120)가 실린더(111)로부터 돌출되어 실린더(111)의 삽입이 곤란하게 될 뿐만 아니라, 삽입시 스프링부재(120)가 변형되거나 스프링부재(120)의 파손이 발생될 수 있다고 하는 문제점이 있다.By the way, in the conventional hermetic rotary compressor, the cylinder 111 in the casing 110 in a state in which the spring member 120 accommodated in the spring receiving portion 118 protrudes out of the cylinder 111. Since the spring member 120 protrudes from the cylinder 111 when the cylinder 111 is inserted, it is difficult to insert the cylinder 111, and the spring member 120 is deformed or inserted when the cylinder 111 is inserted. There is a problem that breakage of the member 120 may occur.

따라서, 본 발명의 목적은, 케이싱의 내부에 실린더를 용이하게 삽입할 수 있으며, 삽입시 부품의 변형 및/또는 파손을 방지될 수 있도록 한 밀폐형 회전 압축기를 제공하는 것이다.Accordingly, it is an object of the present invention to provide a hermetic rotary compressor which can easily insert a cylinder into the casing, and prevents deformation and / or breakage of components upon insertion.

At this time, the spring member 43 is prevented from protruding to the outside of the cylinder 31 by the stopper member 45 so that the cylinder 31 does not interfere with the casing 11, but the inside of the cylindrical portion 12a. It is easily inserted into.

삽입이 완료되면 실린더(31)의 흡입구(32)과 케이싱(11)의 결합부(13)가 상호 연통되도록 한 상태에서 회전자(65)를 회전축(67)에 압입결합한다. 회전자(65)의 결합이 완료되면 상부캡(12b) 및 하부캡(12c)을 원통부(12a)의 상부영역 및 하부영역에 각각 용접 결합되도록 하고, 흡입구(32)에 어큐뮬레이터(21)의 유출관(23)이 결합되도록 한다.When the insertion is completed, the inlet 32 of the cylinder 31 and the coupling portion 13 of the casing 11 are in communication with each other to press-fit the rotor 65 to the rotary shaft 67. When the coupling of the rotor 65 is completed, the upper cap 12b and the lower cap 12c are welded to the upper region and the lower region of the cylindrical portion 12a, respectively, and the inlet port 32 of the accumulator 21 is connected. Allow the outlet pipe 23 to be coupled.

이상 설명한 바와 같이, 본 발명에 따르면, 베인을 탄성적으로 지지하는 스프링부재가 실린더의 외부로 돌출되는 것을 방지하는 스톱퍼를 마련함으로써, 실린더를 케이싱의 내부에 용이하게 삽입할 수 있을 뿐만 아니라, 스프링부재와 접촉되는 케이싱의 내면에 스프링부재의 신축작용에 의해 마모가 발생되던 종래와는 달리 케이싱의 마모가 발생될 염려가 없는 밀폐형 회전 압축기가 제공된다.As described above, according to the present invention, by providing a stopper for preventing the spring member elastically supporting the vanes from protruding to the outside of the cylinder, not only can the cylinder be easily inserted into the casing but also the spring Unlike the conventional case in which abrasion occurs due to the expansion and contraction of the spring member on the inner surface of the casing in contact with the member, there is provided a hermetic rotary compressor which is unlikely to cause abrasion of the casing.
