본 고안은 공기조화기 등에 장착되는 회전압축기에 관한 것으로, 더 상세하게는 밀폐용기에 압축실이 형성된 실린더를 체결하는 이의 체결구조에 관한 것이다.The present invention relates to a rotary compressor mounted on an air conditioner and the like, and more particularly, to a fastening structure thereof for fastening a cylinder in which a compression chamber is formed in a sealed container.
일반적으로 회전압축기는 냉매를 매개체로 하여 압축, 응축, 팽창, 증발과정이 연속적으로 수행되는 공기조화기등의 냉동사이클에서 냉매를 고온 고압으로 압축하여 외부로 내보내는 작용을 한다.In general, the rotary compressor functions to compress the refrigerant to a high temperature and high pressure in a refrigeration cycle such as an air conditioner in which the compression, condensation, expansion, and evaporation processes are continuously performed through the refrigerant, and serves to discharge the refrigerant to the outside.
이러한 기능을 하는 일반적인 회전압축기는 도 1에 도시한 바와 같이, 냉매의 유입과 토출을 안내하도록 냉매흡입관(11)과 냉매토출관(12)이 설치된 밀폐용기(10)내에 냉매를 흡입하여 압축하는 압축부(20)와 압축부(20)를 구동하기 위한 구동부(30)로 구성된다.As shown in FIG. 1, a general rotary compressor having such a function sucks and compresses a refrigerant into an airtight container 10 provided with a refrigerant suction pipe 11 and a refrigerant discharge pipe 12 to guide the inflow and discharge of the refrigerant. It is composed of a compression unit 20 and a drive unit 30 for driving the compression unit 20.
압축부(20)는 압축실(21)을 형성하도록 양면이 개구된 실린더(22)와 압축실(21)내에 마련되어 회전운동 및 미끄럼운동을 하여 냉매를 흡입 압축하는 롤러(23)가 구비되고, 또한 실린더(22)의 일측에는 냉매흡입구(221)가 형성되어 있어서, 냉매흡입관(11)을 통해 밀폐용기(10)내로 들어온 냉매는 이 냉매흡입구(221)를 통해 압축실(21)로 유입된다.The compression unit 20 is provided with a cylinder 22 having both sides opened to form a compression chamber 21 and a roller 23 provided in the compression chamber 21 to suck and compress refrigerant by rotating and sliding movements. In addition, the refrigerant inlet 221 is formed at one side of the cylinder 22, and the refrigerant introduced into the sealed container 10 through the refrigerant inlet pipe 11 flows into the compression chamber 21 through the refrigerant inlet 221. .
그리고 구동부(30)는 롤러(23)와 결합되는 편심부(31)가 일체로 형성된 회전축(32), 회전축(32)에 회전력을 전달하는 회전자(33)와 이 회전자(33)의 외측에는 자장을 형성하는 고정자(34)를 구비한다.In addition, the driving unit 30 includes a rotating shaft 32 in which an eccentric portion 31 coupled with the roller 23 is integrally formed, a rotor 33 transmitting a rotational force to the rotating shaft 32, and an outer side of the rotor 33. It includes a stator 34 that forms a magnetic field.
한편, 실린더(22)를 사이에 두고 설치되어 압축실(21)을 형성함과 동시에 회전축(32)을 회전가능하게 지지하는 상부베어링(40)과 하부베어링(50)이 구성되는데, 이 상,하부베어링(40,50) 각각의 앤드 플레이트(40a,50a)는 압축실(21)의 밀폐를 위해 롤러(23)의 양면과 밀착되도록 구성되어 있다.On the other hand, the upper bearing 40 and the lower bearing 50, which is installed with the cylinder 22 therebetween to form the compression chamber 21 and rotatably support the rotating shaft 32, are configured. The end plates 40a and 50a of each of the lower bearings 40 and 50 are configured to be in close contact with both surfaces of the roller 23 to seal the compression chamber 21.
또한, 실린더(22)에는 편심부(31)에 결합된 롤러(23)의 외주면과 접촉하여 압축실(21)을 흡입실과 토출실로 형성하도록 탄성부재(미도시)에 의해 왕복운동하는 베인(미도시)이 설치된다. 미설명부호 60과 61은 액냉매가 압축실로 유입되는 것을 방지하는 어큐뮤레이터와 일단이 냉매흡입관(11)과 연결되어 기화냉매가 압축실(21)로 안내되는 스탠드파이프이다.In addition, the cylinder 22 has a vane (not shown) which reciprocates by an elastic member (not shown) in contact with the outer circumferential surface of the roller 23 coupled to the eccentric portion 31 to form the compression chamber 21 as the suction chamber and the discharge chamber. Is installed. Reference numerals 60 and 61 are accumulators for preventing liquid refrigerant from flowing into the compression chamber and stand pipes having one end connected to the refrigerant suction pipe 11 to guide the vaporized refrigerant to the compression chamber 21.
이와 같이 구성된 회전압축기는 전원이 인가됨에 따라 구동부(30)의 회전축(32)이 회전하게 되고, 편심부(31)와 함께 롤러(23)가 실린더(22)의 압축실(21)에서 편심 회전운동 및 미끄럼운동을 하게 된다.In the rotary compressor configured as described above, as the power is applied, the rotary shaft 32 of the driving unit 30 rotates, and together with the eccentric portion 31, the roller 23 rotates eccentrically in the compression chamber 21 of the cylinder 22. You will exercise and slide.
이에 따라 냉동사이클의 증발기(미도시)에서 어큐뮤레이터(60)로 들어온 냉매는 스탠드파이프(61)와 냉매흡입관(11), 냉매흡입구(221)를 통해 실린더(22)의 압축실(21)로 유입되고, 계속하여 냉매가 일정압력에 도달하게 되면 밀폐용기(10) 내부로 토출되고, 이 고압 냉매는 냉매토출관(12)를 통해 냉동사이클(미도시)의 응축기(미도시)로 공급된다.Accordingly, the refrigerant entering the accumulator 60 from the evaporator (not shown) of the refrigerating cycle is the compression chamber 21 of the cylinder 22 through the standpipe 61, the refrigerant suction pipe 11, and the refrigerant suction opening 221. When the refrigerant reaches a predetermined pressure and is discharged into the sealed container 10, the high pressure refrigerant is supplied to the condenser (not shown) of the refrigeration cycle (not shown) through the refrigerant discharge pipe 12. do.
한편, 이러한 회전압축기는 밀폐용기(10)의 하부에 압축실(21)이 형성된 실린더(22)가 용접수단에 의해 고정 결합되어 있다.On the other hand, such a rotary compressor is fixed to the cylinder 22, the compression chamber 21 is formed in the lower portion of the sealed container 10 by welding means.
즉, 실린더(22)의 외주면과 대응되는 밀폐용기(10)에는 일정간격 이격된 세 지점에 각각 용접홀(10a)을 미리 천공하고, 실린더(22)를 밀폐용기(10)에 내장한 다음, 밀폐용기(10)의 외부에서 용접홀(10a)을 통하여 밀폐용기(10)와 실린더(22)의 외주면을 용접하였다. 미설명부호 10b는 용입물을 지시한 것으로, 외주면을 용접하는 일명 거스 용접(Girth Welding)으로 밀폐용기(10)에 실린더(22)를 고정하고, 이 후에 어큐뮤레이터(60)의 스탠드파이프(61)가 결합되는 냉매흡입관(11)을 냉매흡입구(221)에 체결한다.That is, in the sealed container 10 corresponding to the outer circumferential surface of the cylinder 22, each of the welding holes 10a are drilled in advance at three points spaced apart from each other, and the cylinder 22 is embedded in the sealed container 10. The outer circumferential surface of the sealed container 10 and the cylinder 22 were welded through the welding hole 10a from the outside of the sealed container 10. Reference numeral 10b indicates the indentation, and the cylinder 22 is fixed to the airtight container 10 by using a so-called Girth welding welding the outer circumferential surface thereof, and then the standpipe of the accumulator 60 ( The refrigerant suction pipe 11 to which the 61 is coupled is fastened to the refrigerant suction opening 221.
그러나 이러한 종래의 회전압축기는 용접과정시 밀폐용기(10)와 실린더(22)가 열변형을 받아 롤러(23)의 외주면과 접하여 압축실(21)을 흡입실과 토출실로 구획하도록 작동하는 베인(미도시)의 왕복운동에 지장을 초래하여 일종의 록킹(Locking) 현상이 발생되고, 아울러 용접불량으로 인해 용접홀(10a)에 틈새가 발생되면 이를 통해 냉매가 누설되는 문제점이 발생된다.However, such a conventional rotary compressor has a vane (not shown) which operates to seal the compression chamber 21 into the suction chamber and the discharge chamber by contacting the outer circumferential surface of the roller 23 due to heat deformation of the sealed container 10 and the cylinder 22 during the welding process. A kind of locking phenomenon occurs by causing a reciprocation of the reciprocating motion, and when a gap occurs in the welding hole 10a due to a poor welding, a problem of leaking refrigerant occurs.
또한 용접을 하기 위해 밀폐용기(10)에는 실린더(22)의 외주연과 정확히 대응되게 용접홀(10a)을 형성하여야 하기 때문에 작업이 난해하여 이의 생산성이 저하되고 제조원가가 상승된다.In addition, since the welding vessel 10a must be formed in the sealed container 10 to exactly correspond to the outer circumference of the cylinder 22 in order to perform the welding, the productivity is difficult and the production cost is increased.
본 고안은 이러한 문제점을 해결하기 위한 것으로, 본 고안의 목적은 밀폐용기에 내곡된 걸림부를 형성하여 내부에 압축실이 형성된 실린더를 억지끼움시킴으로써, 별도의 체결수단 없이 간편하게 실린더를 고정 결합하는 회전압축기를 제공하는 것이다.The present invention is to solve this problem, an object of the present invention is to form a locking portion inside the sealed container by pressing the cylinder formed in the compression chamber therein, a rotary compressor for easily fixing the cylinder without a separate fastening means To provide.

도 2는 본 고안에 따른 회전압축기를 도시한 것으로, 밀폐용기에 실린더가 체결된 구조를 제외하고는 종래의 구성요소와 동일하기 때문에 동일구성요소에 대해서는 동일명칭과 동일부호를 사용하여 간략하게 설명한다.Figure 2 shows a rotary compressor according to the present invention, except for the structure in which the cylinder is fastened to the sealed container is the same as the conventional components for the same components and briefly described using the same name and the same reference numerals. do.
이에 도시한 바와 같이, 회전압축기는 자장을 형성하는 고정자(34), 고정자(34)와 상호작용하여 회전하는 회전자(33)와 이 회전자(33)에 압입되어 같이 회전하는 편심부(31)가 마련된 회전축(32) 등으로 구성된 구동부(30)가 밀폐용기(100)의 상부에 설치되어 있고, 이러한 구동부(30)의 동력을 전달받아 구동하여 냉매를 압축 토출하는 압축부(20)는 밀폐용기(100)의 하부에 구성되어 있다.As shown therein, the rotary compressor has a stator 34 which forms a magnetic field, a rotor 33 which rotates in interaction with the stator 34, and an eccentric portion 31 which is pressed into the rotor 33 and rotated together. A driving unit 30 including a rotating shaft 32 provided with a) is installed at the upper portion of the sealed container 100, and the compression unit 20 for driving by receiving the power of the driving unit 30 to compress and discharge the refrigerant is It is comprised in the lower part of the airtight container 100.
이 압축부(20)는 냉매가 흡입 압축되는 압축실(21)이 형성되도록 양면이 개구된 실린더(22)와 압축실(21)내부에서 편심부(31)에 결합되어 회전하는 롤러(23), 실린더(22)의 상하부에 설치되어 압축실(21)을 형성하며 회전축(32)을 회전가능하게 지지하는 상부베어링(40)과 하부베어링(50)이 구성된다. 그리고 실린더(22) 일측에는 냉매흡입구(221)가 형성되고 여기에는 어큐뮤레이터(60)의 스탠드파이프(61)와 결합되는 냉매흡입관(11)이 체결된다. 미설명부호 12는 고압의 냉매가 토출되는 냉매토출관이다.The compression unit 20 is coupled to the eccentric portion 31 inside the cylinder 22 and the compression chamber 21 having both sides open so that the compression chamber 21 through which the refrigerant is sucked and compressed is rotated 23. The upper bearing 40 and the lower bearing 50 are installed at upper and lower portions of the cylinder 22 to form the compression chamber 21 and rotatably support the rotating shaft 32. A refrigerant suction opening 221 is formed at one side of the cylinder 22, and a refrigerant suction pipe 11 coupled to the stand pipe 61 of the accumulator 60 is fastened thereto. Reference numeral 12 is a refrigerant discharge tube through which the high pressure refrigerant is discharged.
한편 본 고안의 특징적인 요소로 밀폐용기(100) 저부에는 압축실(21)이 형성된 실린더(22)가 억지끼움되어 있다. 이를 위해 밀폐용기(100) 하측 외주부에는 소정깊이로 내곡된 걸림부(100a)가 형성되어 있다.On the other hand, as a characteristic element of the present invention, the cylinder 22 in which the compression chamber 21 is formed is inserted into the bottom of the sealed container 100. To this end, the lower outer peripheral portion of the airtight container 100 is formed with a locking portion 100a curved to a predetermined depth.
즉, 이 걸림부(100a)가 형성된 밀폐용기(100) 내에 실린더(22)를 유압을 이용하여 강제로 삽입시키면, 걸림부(100a)에 의해 실린더(22)의 외주면이 꽉 끼게 되어 별도의 체결수단 없이 고정 결합된다. 그리고 이 후에 실린더(22)에 형성된 냉매흡입구(221)에 냉매흡입관(11)과 어큐뮤레이터(60)의 스탠드파이프(61)를 체결하면 된다.That is, when the cylinder 22 is forcibly inserted into the sealed container 100 in which the locking portion 100a is formed by using hydraulic pressure, the outer peripheral surface of the cylinder 22 is tightly clamped by the locking portion 100a, so that a separate fastening is performed. It is fixedly coupled without means. After that, the coolant suction pipe 11 and the stand pipe 61 of the accumulator 60 may be fastened to the coolant suction opening 221 formed in the cylinder 22.
