흡입연결관이 설치된 밀폐형 압축기{Absorption Connecting Tube of Hermetic Compressor}Absorption Connecting Tube of Hermetic Compressor

본 발명은 흡입연결관이 설치된 밀폐형 압축기에 관한 것으로, 특히 자성체를 이용하여 흡입관과 흡입머플러 사이를 긴밀하게 밀착시켜 진동 및 소음 물론, 상기 흡입연결관 내로 윤활유가 유입되는 것을 방지하는 흡입연결관이 설치된 밀폐형 압축기에 관한 것이다.The present invention relates to a hermetic compressor provided with a suction connection pipe, and in particular, a suction connection pipe that closely connects between the suction pipe and the suction muffler using a magnetic material to prevent lubricating oil from flowing into the suction connection pipe as well as vibration and noise. It relates to a hermetic compressor installed.

일반적으로 밀폐형 압축기는 냉장고나 공기조화기 등에 사용되는 냉동사이클에서 냉매를 압축하기 위해 채용되는 것으로, 외관을 형성하는 밀폐용기와, 상기 밀폐용기의 내부에 마련되어 냉매를 압축하는 압축장치와, 상기 압축장치에 구동력을 전달하는 구동장치로 구성된다.In general, a hermetic compressor is used to compress a refrigerant in a refrigeration cycle used in a refrigerator or an air conditioner, and includes a sealed container for forming an exterior, a compression device provided inside the sealed container to compress a refrigerant, and the compression. It consists of a driving device for transmitting a driving force to the device.

이하, 도 1을 참조하여 종래기술에 따른 밀폐형 압축기의 대표적 구성에 대하여 개략적으로 설명한다.Hereinafter, a representative configuration of a hermetic compressor according to the prior art will be described with reference to FIG. 1.

먼저, 밀폐용기(10)의 일측과 타측에는 각각 냉동사이클의 증발기를 거친 저압의 냉매를 내부로 안내하는 흡입관(1)과, 압축된 고압의 냉매를 응축기 측으로 안내하는 토출관(2)이 설치된다.First, the suction tube 1 for guiding the low pressure refrigerant through the evaporator of the refrigeration cycle into the inside and the discharge tube 2 for guiding the compressed high pressure refrigerant to the condenser side are installed on one side and the other side of the sealed container 10, respectively. do.

또한, 압축장치(20)는 냉매가 압축되는 압축실(21a)을 형성하는 실린더(21)와, 상기 압축실(21a) 내부에서 직선왕복 운동하며 냉매를 압축하는 피스톤(22)과, 압축실(21a)을 밀폐시키도록 실린더(21)에 결합되며 냉매흡입실과 냉매토출실이 구획 형성된 실린더헤드(23)와, 실린더(21)와 실린더헤드(23) 사이에 개재되는 밸브장치(VA)로 구성된다.In addition, the compression device 20 includes a cylinder 21 forming a compression chamber 21a in which the refrigerant is compressed, a piston 22 for linearly reciprocating and compressing the refrigerant in the compression chamber 21a, and a compression chamber. A cylinder head 23 coupled to the cylinder 21 to seal the 21a, and having a refrigerant suction chamber and a refrigerant discharge chamber partitioned therebetween, and a valve apparatus VA interposed between the cylinder 21 and the cylinder head 23. It is composed.

또한, 상기 실린더헤드(23)의 냉매흡입실 측에는 압축실(21a)로 흡입되는 흡입냉매의 유동소음을 저감시키기 위해 흡입머플러(40)가 설치된다.In addition, a suction muffler 40 is installed at the refrigerant suction chamber side of the cylinder head 23 to reduce the flow noise of the suction refrigerant sucked into the compression chamber 21a.

그리고, 상기 흡입머플러(40)에는 흡입관(1)을 통해 유입되는 저온의 냉매가 밀폐용기(10) 내부의 윤활유와 혼합되지 않도록 원활하게 안내하는 흡입연결관(11)이 설치된다.In addition, the suction muffler 40 is provided with a suction connecting pipe 11 for smoothly guiding the refrigerant at low temperature flowing through the suction pipe 1 with the lubricant inside the sealed container 10.

한편, 상기 구동장치(30)는 피스톤(22)이 압축실(21a) 내부에서 직선왕복운동할 수 있도록 구동력을 전달하는 구동축(31)과, 상기 구동축(31)을 회전시키는 고정자(32)와 회전자(33)로 구성된다.On the other hand, the drive device 30 includes a drive shaft 31 for transmitting a driving force so that the piston 22 can linearly reciprocate in the compression chamber 21a, and a stator 32 for rotating the drive shaft 31; It consists of a rotor 33.

따라서, 상기 구동축(31)이 구동하면 압축실(21a) 내부는 피스톤(22)이 직선왕복운동 하는 과정에서 압축실(21a) 내부에 압력차를 발생시키고, 이 압력차에 의해 증발기를 통과한 저압의 냉매가 흡입관(1), 흡입머플러(40) 및 냉매흡입실을 순차적으로 거쳐 압축실(21a)로 흡입되어 압축되며, 이후 고압의 상태로 압축된 냉매는 냉매토출실과 토출관(2)을 거쳐 응축기 측으로 공급된다.Therefore, when the drive shaft 31 is driven, the compression chamber 21a generates a pressure difference inside the compression chamber 21a during the linear reciprocating motion of the piston 22, and passes through the evaporator by this pressure difference. The low pressure refrigerant is sucked into the compression chamber 21a through the suction pipe 1, the suction muffler 40 and the refrigerant suction chamber sequentially and then compressed, and the refrigerant compressed at a high pressure is then discharged from the refrigerant discharge chamber and the discharge tube 2 Is fed to the condenser side.

In addition, as the strong vibration around the suction connection tube and the sealed container continues for a long time, the cohesion may be weakened, and a gap may occur. Consequently, refrigerant is leaked between the gaps or lubricant is introduced to lubricate the compression device, thereby compressing the compressor. There was a problem that the efficiency is lowered.

그리고, 상기 밀폐용기(10) 내부에는 흡입관(1)을 통해 흡입되는 냉매의 유동소음을 저감시키기 위해 흡입머플러(40)가 설치된다.In addition, a suction muffler 40 is installed in the sealed container 10 to reduce the flow noise of the refrigerant sucked through the suction pipe 1.

구체적으로, 도 1과 도 2에 도시한 바와 같이, 상기 흡입머플러(40)는 상기 압축실(21a) 측과 연계되는 상부 측의 제1 몸체(40a)와 상기 흡입관(1) 측과 연계되는 하부 측의 제2 몸체(40b)가 상호 결합되어 내부공간이 하나의 공명공간을 형성하며, 이러한 상기 제1 몸체(40a)와 제2 몸체(40b)는 각각 사출물로 제작된다.Specifically, as shown in FIGS. 1 and 2, the suction muffler 40 is connected to the first body 40a of the upper side associated with the compression chamber 21a side and the suction tube 1 side.

이하, 도 2 내지 도 5를 참조하여 본 발명의 특징적인 구성요소인 흡입연결관(100)에 대하여 상세히 설명한다. Hereinafter, the suction connecting pipe 100 which is a characteristic component of the present invention will be described in detail with reference to FIGS. 2 to 5.

본 발명의 실시예에 따른 흡입연결관(100)은 흡입관(1)과 흡입머플러(40) 사이에 개재되되, 상기 흡입관(1)으로부터 배출되는 냉매의 이동압력에 신축이 가능토록 그 길이방향으로 산(100a)과 골(100b)을 교대로 형성하여 주름지도록 형성되며, 그 일단은 상기 흡입머플러(40)에 결합되고, 타단은 상기 흡입관(1)이 연통된 밀폐용기(10)의 내벽면 주변을 밀봉하는 상태로 밀착 고정된다.The suction connection pipe 100 according to the embodiment of the present invention is interposed between the suction pipe 1 and the suction muffler 40, and extends in the longitudinal direction so that expansion and contraction are possible in the moving pressure of the refrigerant discharged from the suction pipe 1.

It provides stable adhesion even with pressure changes.

한편, 상기 자성체는 자력을 이용하여 밀폐용기(10)의 내벽면에 흡입연결관(100)이 용이하게 부착되어 긴밀한 밀봉상태를 유지시키는 역할을 수행한다.On the other hand, the magnetic material serves to maintain a tight sealing state by the suction connecting pipe 100 is easily attached to the inner wall surface of the sealed container 10 by using a magnetic force.

도 3에 도시한 바와 같이, 상기 자성체(120)에는 흡입연결관(100)의 타단면에 끼움 결합되는 결합부(121)를 형성한다. 물론, 상기 흡입연결관(100)의 타단면에는 상기 결합부(121)에 대응하는 결합홈(101)이 형성되는 것은 당연하다.As shown in FIG. 3, the magnetic body 120 forms a coupling part 121 fitted to the other end surface of the suction connection pipe 100. Of course, the other end surface of the suction connection pipe 100 is a natural coupling groove 101 corresponding to the coupling portion 121 is formed.

마찬가지로, 상기 자성체(120)는 자체가 용이하게 변형될 수 있는 플렉시블한 소재의 자석고무링으로 구성될 수도 있다.Similarly, the magnetic body 120 may be composed of a magnetic rubber ring of a flexible material that can be easily deformed itself.

그 밖에, 상기 자성체(120)와 흡입연결관(100)과의 결합구조는 접착수지를 사용하거나 나사결합식에 의해 일체화할 수 있다.In addition, the coupling structure of the magnetic body 120 and the suction connecting pipe 100 may be integrated by using an adhesive resin or screwed.

특히, 상기 자성체(120)의 둘레 면적은 흡입연결관(100)의 타단 둘레 면적보다 넓은 크기로 형성하여 상기 밀폐용기(10) 내벽면과의 밀착력을 보다 안정적으로 유지시킬 수 있도록 하는 것이 바람직하다.In particular, it is preferable that the circumferential area of the magnetic body 120 is formed to have a size larger than that of the other end circumference of the suction connection pipe 100 so as to maintain the adhesion force with the inner wall surface of the sealed container 10 more stably. .

결국, 상기 흡입연결관(100)은 자성체(120)에 의해 급격한 냉매 이동에 따른 압력변화에도 안정적인 밀착력을 제공하므로 상기 밀폐용기(10) 내부에 설치된 압축장치를 윤활시키는 윤활유가 비산되어 상기 흡입연결관(100)의 내부로 유입되는 것이 방지될 뿐만 아니라 상기 흡입연결관(100)의 내부를 통과하는 냉매가 외부로 누출되는 것이 보다 효율적으로 차단된다.As a result, the suction connection pipe 100 provides stable adhesion even when the pressure changes due to the rapid movement of the refrigerant by the magnetic body 120, so that lubricating oil for lubricating the compression device installed in the sealed container 10 is scattered. Not only the inside of the pipe 100 is prevented from being introduced, but also the refrigerant passing through the inside of the suction connection pipe 100 is leaked to the outside more efficiently.

한편, 도 4는 상기 흡입연결관(100)에 결합되는 자성체의 다른 실시예를 나타낸 것으로, 자성체(120')가 흡입연결관(100)의 타단 외면둘레를 감싸는 상태에서 상기 밀폐용기(10)의 내벽면에 부착된다.On the other hand, Figure 4 shows another embodiment of the magnetic body coupled to the suction connecting pipe 100, the sealed container 10 in a state in which the magnetic body 120 'wraps around the outer surface of the other end of the suction connecting pipe 100 Is attached to the inner wall surface.

또한, 도 6에 도시한 바와 같이, 상기 자성체(120'')는 소정의 입자형태로 이루어져 상기 흡입연결관(100)을 사출시키는 과정에서 내재시킴으로써 상기 흡입연결관(100) 전체가 자성력을 갖도록 할 수도 있다.In addition, as shown in FIG. 6, the magnetic body 120 ″ is formed in a predetermined particle shape and is embedded in the process of injecting the suction connecting tube 100 to thereby generate the magnetic force of the entire suction connecting tube 100. You can also have it.

이와 같이, 본 발명의 실시예에 따른 흡입연결관(100)은 주름관의 형태로 이루어짐에 따라 흡입관(1)으로부터 냉매 이동에 따른 맥동현상에 대응하여 신축변형이 유연하게 이루어져 떨림과 소음을 감소시킬 수 있을 뿐만 아니라, 자성체(120)의 밀착력에 내부로 윤활유가 유입되거나 냉매가 외부로 유출되는 현상을 효과적으로 방지할 있다.As such, the suction connection pipe 100 according to the embodiment of the present invention is made in the form of a corrugated pipe so that the elastic deformation is flexibly made in response to the pulsation phenomenon caused by the movement of the refrigerant from the suction pipe 1 to reduce vibration and noise. In addition, the lubricating oil may be introduced into the adhesion force of the magnetic body 120 or the refrigerant may be effectively prevented from flowing out.

이상에서는 본 발명의 바람직한 실시예를 설명하였으나, 본 발명의 범위는 이같은 특정 실시예에만 한정되지 않으며, 해당분야에서 통상의 지식을 가진자라면 본 발명의 특허청구범위 내에 기재된 범주 내에서 적절하게 변경이 가능할 것이다.Although the preferred embodiments of the present invention have been described above, the scope of the present invention is not limited to such specific embodiments, and those skilled in the art may appropriately change within the scope described in the claims of the present invention. This will be possible.
