Description
본 발명은 증발기로부터의 냉매를 전달하는 흡입관과, 흡입관으로부터의 냉매를 수령하여 냉매압축용 실린더장치에 공급하는 머플러와, 흡입관과 머플러의 흡입포트를 연결하는 흡입스프링관을 갖는 밀폐형압축기에 관한 것이다.The present invention relates to a hermetic compressor having a suction pipe for transferring refrigerant from an evaporator, a muffler for receiving the refrigerant from the suction pipe to supply the refrigerant to the refrigerant compression cylinder device, and a suction spring tube for connecting the suction pipe to the suction port of the muffler .
냉장고 등의 냉동장치에서는 증발기로부터의 기상냉매를 압축하여 고압의 냉매기체로 만들어 응축기에 제공하는 압축기를 구비하고 있다. 제9도는 종래의 밀폐형압축기의 머플러 부분의 부분단면도이다. 이 도면에 도시된 바와 같이, 밀폐형압축기의 하부영역에 설치되는 냉매압축용 실린더장치(101)의 실린더헤드 부분에 설치되는 머플러(103)는 냉매흡입관(105)을 통해 외부로부터 유입되는 냉매를 수령하여 냉매흡입구를 통해 실린더장치(103) 내로 공급할 수 있도록 되어 있다. 머플러(103)에는 외부로부터 냉매가 유입되는 흡입관(105)이 연결되어 있고, 흡입관(105)은 도시않은 증발기와 연결있다.BACKGROUND ART [0002] In a refrigeration apparatus such as a refrigerator, there is provided a compressor which compresses gaseous refrigerant from an evaporator into a high-pressure refrigerant gas and provides it to a condenser. 9 is a partial cross-sectional view of a muffler portion of a conventional hermetic compressor. As shown in this figure, the muffler 103 installed in the cylinder head portion of the refrigerant compression cylinder device 101 installed in the lower region of the hermetic compressor receives the refrigerant flowing from the outside through the refrigerant suction pipe 105 And can be supplied into the cylinder device 103 through the refrigerant suction port. The muffler 103 is connected to a suction pipe 105 through which refrigerant flows from the outside, and the suction pipe 105 is connected to an evaporator not shown.
흡입관(105)과 머플러(103) 사이에는 관상의 흡입스프링관(107)이 개재되어 있다. 흡입스프링관(107)의 일단은 흡입관(105)의 외경부에 강제압입되어 끼워져 있고, 타단은 머플러(103)의 흡입포트(109의 내경부에 헐겁게 끼워져 있어, 흡입관(105)을 통해 유동해 온 냉매가 흡입스프링관(107)을 통과하여 머플러(103)로 유입되도록 되어 있다.A tubular suction spring tube 107 is interposed between the suction pipe 105 and the muffler 103. One end of the suction spring tube 107 is forcibly press-fitted into the outer diameter portion of the suction pipe 105 and the other end is loosely fitted in the inner diameter portion of the suction port 109 of the muffler 103 to flow through the suction pipe 105 And the refrigerant is introduced into the muffler 103 through the suction spring tube 107.
이러한 구성에 의하여, 압축기가 구동할 때, 흡입관(105) 내부를 유동해 온 냉매는 흡입스프링관(107)을 통과하여, 흡입머플러(103)로 유입되어 실린더헤드 부분의 냉매흡입구를 통해 실린더장치(101) 내부로 흡입되어 압축된다. 이 때, 압축기 구동시 발생하는 진동 등의 영향으로 실린더장치(101)와 일체로 결합된 머플러(103)가 흔들려서 흡입스프링관(107)이 머플러(103)의 흡입포트(109)의 내경부와 마찰접촉하면서 요동하여 소음을 발생시키게 되고, 흡입스프링관(105)이 흡입포트(109)로부터 이탈하는 경우가 발생하게 된다. 또한, 요동에 의해 압축기본체가 기울어지게 되면, 흡입스프링관(107)이 휘어지면서 생기는 틈새를 통해 냉매가 외부로 새어나가서, 실린더장치(101) 내부로의 냉매유입이 원활하게 이루어지지 않게 되어, 압축기의 효율이 저하된다.With this configuration, when the compressor is driven, the refrigerant flowing in the suction pipe 105 flows into the suction muffler 103 through the suction spring tube 107 and flows through the refrigerant suction port of the cylinder head portion, (101). At this time, the muffler 103 integrated with the cylinder device 101 is shaken due to the influence of vibration or the like generated when the compressor is driven, so that the suction spring tube 107 contacts the inner diameter portion of the suction port 109 of the muffler 103 The suction spring tube 105 is disengaged from the suction port 109. In this case, Further, when the compressor main body is tilted by the rocking motion, the refrigerant leaks to the outside through the gap formed by the bending of the suction spring tube 107, so that the refrigerant can not flow smoothly into the cylinder device 101, The efficiency of the compressor is lowered.
따라서, 본 발명의 목적은, 흡입스프링관의 결합구조를 개선하여, 소음발생이 저감되고, 흡입스프링관이 머플러의 흡입포트로부터 쉽게 이탈하지 아니하며, 흡입스프링관 밖으로 냉매가 새어나가는 것이 방지되어, 효율이 향상되는 밀폐형압축기를 제공하는 것이다.SUMMARY OF THE INVENTION It is therefore an object of the present invention to improve the coupling structure of the suction spring tube to reduce the generation of noise and to prevent the suction spring tube from easily separating from the suction port of the muffler and to prevent the refrigerant from leaking out of the suction spring tube, And to provide a hermetic compressor having improved efficiency.

상기 목적은, 본 발명에 따라, 증발기로부터의 냉매를 전달하는 흡입관과, 흡입관으로부터의 냉매를 수령하여 냉매압축용 실린더장치에 공급하는 머플러와, 흡입관과 머플러의 흡입포트를 연결하는 흡입스프링관을 갖는 밀폐형압축기에 있어서, 머플러의 흡입포트의 내부에 고정설치되며, 흡입스프링관의 일단부가 고정되는 이음용 그로메트를 가지며, 흡입스프링관의 타단부에는 상기 흡입관의 말단부가 유동가능하도록 삽입되는 것을 특징으로 하는 밀폐형압축기에 의해 달성된다.According to the present invention, the above objects can be accomplished by a refrigerant compressor comprising a suction pipe for transferring refrigerant from an evaporator, a muffler for receiving refrigerant from the suction pipe and supplying the refrigerant to the refrigerant compression cylinder device, and a suction spring tube for connecting the suction pipe to the suction port of the muffler The suction tube has a connecting grommet fixed to the suction port of the muffler and fixed at one end of the suction spring tube and inserted into the other end of the suction spring tube so as to allow the distal end of the suction tube to flow The invention is achieved by a hermetically sealed compressor.
여기서, 이음용 그로메트의 외표면에 외주그루브를 형성하고, 흡입포트의 내벽면에는 외주그루브에 맞물리는 내주리브를 형성하면 이음용 그로메트가 흡입포트에 용이하게 조립될 수 있다. 혹은, 이음용 그로메트의 외표면에 외향외주리브를 형성하고, 흡입포트의 내벽면에는 외향외주리브에 맞물리는 내주그루브를 형성할 수도 있다.Here, the outer grooves are formed on the outer surface of the coupling grommet, and the inner grooves of the suction port are formed with inner ribs engaged with the outer grooves, so that the grommet for joining can be easily assembled to the suction port. Alternatively, the outer circumferential rib may be formed on the outer surface of the grommet for joining, and the inner wall surface of the suction port may be formed with an inner circumferential groove engaged with the outward outer circumferential rib.
이음용 그로메트의 외표면에는 흡입스프링관의 단부가 걸릴 수 있는 걸림홈이 형성되는 것이 바람직하다. 이에 부합하여, 흡입스프링관의 이음용 그로메트측 단부는 걸림홈에 걸릴 수 있도록 관경보다 작은 직경을 갖도록 형성된다. 또한, 머플러가 이음용 그로메트의 중심축선을 포함한 평면을 따라 분리가능한 한 쌍의 머플러부분으로 이루어지면 이음용 그로메트를 머플러에 조립하기가 용이해진다.It is preferable that an engagement groove is formed on the outer surface of the grommet for connection so that the end portion of the suction spring tube can be caught. Correspondingly, the grommet-side end of the suction spring tube is formed so as to have a diameter smaller than the diameter of the tube so as to be caught in the engaging groove. Further, if the muffler is made up of a pair of muffler parts which can be separated along a plane including the center axis of the joining grommet, it is easy to assemble the joining grommet into the muffler.
한편, 흡입관이 흡입스프링관 내에 삽입되는 단부영역에서 반경방향으로 외향돌출된 고리상의 벌징부를 형성하면, 흡입스프링관과 흡입관 사이의 접촉면적을 줄일 수 있다.On the other hand, when the suction pipe forms a ring-shaped bulge portion protruding radially outwardly in the end region into which the suction spring tube is inserted, the contact area between the suction spring tube and the suction pipe can be reduced.
이음용 그로메트의 단부영역에는 흡입스프링관이 견고하게 결합되도록 걸림확경부가 형성되도록 할 수도 있다. 이 경우, 흡입스프링관의 단부에는 이음용 그로메트의 걸림확경부에 대응하도록 걸림축경부가 형성된다. 머플러는 이음용 그로메트의 중심축선을 포함한 평면을 따라 분리가능한 한 쌍의 머플러부분으로 형성함으로써, 조립을 용이하게 할 수 있다.And a hooking diameter portion may be formed in the end region of the grommet for joining so that the suction spring tube is firmly coupled. In this case, at the end of the suction spring tube, the engagement shaft diameter portion is formed so as to correspond to the engagement enlarged diameter portion of the joining grommet. The muffler can be formed as a pair of muffler parts separable along the plane including the center axis of the grommet for joining, thereby facilitating the assembly.
이하에서 첨부도면을 참조하여 본 발명을 상세히 설명한다.BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in detail below with reference to the accompanying drawings.
제1도는 본 발명에 따른 밀폐형압축기의 부분단면도이다. 이 도면에 도시된 바와 같이, 압축기의 외부케이싱(2) 내부에는 압축기본체(4)가 수용되어 있고, 저면에는 오일(6)이 고여 있다. 압축기본체(4)의 하부에는 냉매압축용 실린더장치(1)가 설치되어 있고, 실린더장치(1)의 실린더헤드에는 실린더장치(1) 내부로 냉매를 공급하는 머플러(3)가 실린더장치(1)의 냉매흡입구와 연통되도록 설치되어 있다. 머플러(3)의 흡입포트(9)에는 흡입관(5)이 연결되어 있고, 흡입관(5)은 외부케이싱(2) 외부의 도시않은 증발기와 연결됨으로써, 증발기로부터의 냉매가 외부케이싱(2) 내부로 유입될 수 있도록 되어 있다.FIG. 1 is a partial cross-sectional view of a hermetic compressor according to the present invention. As shown in the figure, the compressor main body 4 is accommodated in the outer casing 2 of the compressor, and the oil 6 is accommodated in the bottom surface thereof. The cylinder head of the cylinder apparatus 1 is provided with a cylinder apparatus 1 for compressing refrigerant and a muffler 3 for supplying the refrigerant into the cylinder apparatus 1 is connected to the cylinder apparatus 1 And the refrigerant suction port of the compressor. The suction pipe 5 is connected to the suction port 9 of the muffler 3 and the suction pipe 5 is connected to an evaporator not shown on the outside of the outer casing 2 so that the refrigerant from the evaporator is discharged to the inside of the outer casing 2 As shown in FIG.
제2도는 제1도의 머플러 부분의 분해사시도이고, 제3도는 제2도가 조립된 상태의 사시도, 제4도는 흡입포트 부분의 조립상태 부분확대단면도이다. 이들 도면에 도시된 바와 같이, 머플러(3)는 분리가능한 한 쌍의 머플러부분으로 이루어져 있고, 이 한쌍의 머플러부분이 조립되어 관상의 흡입스프링관(7)이 연결되는 흡입포트(9)가 형성되도록 되어 있다. 흡입포트(9)의 내부에는 흡입스프링관(7)의 일단이 고정되는 이음용 그로메트(11)가 끼워져 고정설치되어 있다.FIG. 2 is an exploded perspective view of the muffler portion of FIG. 1, FIG. 3 is a perspective view of the state in which the second view is assembled, and FIG. As shown in these drawings, the muffler 3 is composed of a pair of separable muffler parts, and a pair of muffler parts are assembled to form a suction port 9 to which a tubular suction spring tube 7 is connected . In the suction port 9, a coupling grommet 11 to which one end of the suction spring tube 7 is fixed is fitted and fixed.
이음용 그로메트(11)는 외표면에 외주그루브(12)가 형성되어 흡입포트(9)의 내벽면에 형성된 내주리브(10)와 맞물려 형상맞춤된다. 또한, 이음용 그로메트(11)의 하단부의 외표면에는, 흡입스프링관(7)의 단부가 걸릴 수 있도록 V자형의 걸림홈(13)이 형성되어, 흡입스프링관(5)의 일단부가 이격되어 형성된 걸림링(8)이 걸림홈(13)에 삽입 고정됨으로써, 흡입스프링관(7)이 머플러(3)에 결합된다.The connecting grommet 11 has an outer circumferential groove 12 formed on an outer surface thereof and engaged with the inner circumferential rib 10 formed on the inner wall surface of the suction port 9 to be shaped. A V-shaped latching groove 13 is formed on the outer surface of the lower end of the connecting grommet 11 so that the end of the suction spring tube 7 can be caught, The suction spring tube 7 is engaged with the muffler 3 by inserting and fixing the engaging ring 8 formed in the engaging groove 13.
흡입스프링관(7)의 타단부에는 흡입관(5)의 단부가 삽입되고, 흡입관(5)은 그 단부영역의 직경이 관경보다 작도록 되어 있어, 흡입스프링관(7)이 흡입관(5)의 단부영역의 외표면을 따라 유동가능하게 접촉할 수 있도록 되어 있다.The end of the suction pipe 5 is inserted into the other end of the suction spring tube 7 so that the diameter of the end area of the suction pipe 5 is smaller than the diameter of the suction pipe 5, So as to be flowable along the outer surface of the end region.
이러한 구성에 의하여, 압축기가 구동할 때, 실린더장치(1)가 요동하여 머플러(3)가 일체로 요동하게 되면, 머플러(3)의 흡입포트(9)의 내벽면에 설치된 이음용 그로메트(11)에 고정된 흡입스프링관(7)도 함께 요동하게 된다. 흡입스프링관(7)이 요동하게 되면, 흡입스프링관(1)의 단부는 흡입관(5) 단부영역의 외표면을 따라 유동접촉하게 된다. 이에 따라, 흡입스프링관(1)이 휘어지지 않게 되어, 냉매가 밖으로 새어나가지 않는다. 또한, 흡입스프링관(1)이 흡입포트(9)나 흡입관(5)으로부터 쉽게 이탈하지 아니하고 소음발생도 저감된다.With this configuration, when the compressor 1 is driven, the cylinder apparatus 1 swings and the muffler 3 swings integrally. When the compressor 1 is driven, the connecting grommet (not shown) provided on the inner wall surface of the suction port 9 of the muffler 3 The suction spring tube 7 fixed to the suction tube 11 also swings together. When the suction spring tube 7 is pivoted, the end of the suction spring tube 1 becomes in flow contact along the outer surface of the end region of the suction tube 5. As a result, the suction spring tube 1 is not bent, and the refrigerant does not leak out. Further, the suction spring tube 1 is not easily separated from the suction port 9 and the suction pipe 5, and noise generation is also reduced.
제5도는 본 발명의 다른 실시예에 따른, 머플러부분의 분해사시도, 제6도는 제5도의 흡입포트부분의 조립상태 확대단면도이다. 이 실시예에서는, 이음용 그로메트(21)의 외표면에 외향돌출된 외주리브(22)를 형성하고, 흡입포트(9)의 내벽면에 외주리브(22)에 맞물리는 내주그루브(23)를 형성하여, 외주리브(22)가 내주그루브(23)와 형상맞춤되게 이음용 그로메트(21)를 머를러(3)의 흡입포트(9) 내에 끼워 고정하도록 되어 있다. 이음용 그로메트(21)의 하단부에는, 전술한 실시예와 마찬가지로, 흡입스프링관(7)의 단부에 형성된 걸림링(8)이 삽입고정될 수 있는 V자형의 걸림홈(13)이 형성되어 있다. 이에 따라, 흡입스프링관(7)은 일단부가 이음용 그로메트(21)에 고정되고, 타단부가 흡입관(5)의 말단부에 유동가능하게 삽입되어, 요동에도 쉽게 이탈하지 않는다.FIG. 5 is an exploded perspective view of a muffler portion according to another embodiment of the present invention, and FIG. 6 is an enlarged sectional view of an assembled state of the suction port portion of FIG. In this embodiment, an outer circumferential rib 22 protruding outward is formed on the outer surface of the coupling grommet 21, and an inner groove 23 engaged with the outer circumferential rib 22 is formed on the inner wall surface of the suction port 9, And the connecting grommet 21 is fitted in the suction port 9 of the muffler 3 so that the outer circumferential rib 22 is shaped like the inner circumferential groove 23. [ A V-shaped latching groove 13 is formed at the lower end of the coupling grommet 21 so that the latching ring 8 formed at the end of the suction spring tube 7 can be inserted and fixed in the same manner as in the above- have. Accordingly, the suction spring tube 7 is fixed at one end to the grommet 21 for jointing, and the other end is inserted into the distal end portion of the suction tube 5 so as to be able to flow, so that it does not easily come off.
제7도는 본발명의 또 다른 실시예에 따른, 머플러부분의 분해사시도이고, 제8도는 제7도의 조립단면도이다. 이 실시예에서는, 이음용 그로메트(31)의 외표면에 형성된 외주그루브(33)가 머플러(3)의 흡입포트(9) 내에 형성된 내주리브(34)와 형상맞춤되어 고정된다. 이음용 그로메트(3)의 흡입스프링관(35)이 접속되는 단부영역에는, 관경보다 직경이 더 큰 걸림확경부(32)가 형성되어 있고, 흡입스프링관(37)의 이음용 그로메트(31)측 단부영역에는 걸림확경부(32)에 대응하는 걸림축경부(38)가 형성되어 있다. 흡입스프링관(37)의 걸림축경부(38)의 반대측 단부 내에 삽입되는 흡입관(35)의 단부에는, 반경방향으로 외향돌출된 고리상의 벌징부(36)가 형성되어, 흡입관(35)이 흡입스프링관(37)과 견고하게 결합된다. 이에 따라, 흡입스프링관(37)이 머플러(31)의 흡입포트(9) 및 흡입관(35)으로부터 쉽게 이탈하지 않게 된다.FIG. 7 is an exploded perspective view of a muffler portion according to still another embodiment of the present invention, and FIG. 8 is an assembled cross-sectional view of FIG. In this embodiment, the outer circumferential groove 33 formed on the outer surface of the joining grommet 31 is shaped and fixed to the inner circumferential rib 34 formed in the suction port 9 of the muffler 3. The engagement groove portion 32 of the suction spring tube 37 is formed with a larger diameter than that of the diameter of the coupling spring tube 35 of the coupling grommet 3, 31) is formed in the side end region thereof with an engagement-reduced-diameter portion (38) corresponding to the engagement-expanded portion (32). A ring-shaped bulging portion 36 protruding outward in the radial direction is formed at the end of the suction pipe 35 which is inserted into the opposite end of the suction spring tube 37 on the opposite side of the engagement reducing diameter portion 38, And is firmly coupled to the spring tube 37. Accordingly, the suction spring tube 37 is not easily separated from the suction port 9 and the suction pipe 35 of the muffler 31.
이상 설명한 바와 같이, 본 발명에 따르면, 흡입스프링관의 결합구조를 개선하여, 소음발생이 저감되고, 흡입스프링관이 머플러의 흡입포트로부터 쉽게 이탈하지 아니하며, 흡입스프링관 밖으로 냉매가 새어나가는 것이 방지되어, 성능이 향상되는 밀폐형압축기가 제공된다.As described above, according to the present invention, it is possible to improve the coupling structure of the suction spring tube, to reduce noise generation, to prevent the suction spring tube from easily separating from the suction port of the muffler and to prevent the refrigerant from leaking out of the suction spring tube Thereby providing a hermetic compressor with improved performance.
