본 고안은 밀폐형 압축기의 냉매 가스 흡입 순환기에 관한 것으로 밀폐 용기에 고정된 흡입 튜브를 머플러에 직접 연결 되도록 틈새가 없는 후렉시블 스프링을 설치하여 증발기의 저온 저압의 냉매를 밀폐 용기내에 확산시키지 않고 직접 흡입머플러로 유입되도록 하여 흡입 효율을 높이게 하여 머플러에 배플(Baffle)장치로서 압축 소음을 차단 할 수 있게함에 주 안점을 둔 것이다.The present invention relates to a refrigerant gas suction circulator of a hermetic compressor, and installs a flexible spring without a gap so that the suction tube fixed in the hermetic container is directly connected to the muffler so that the low temperature low pressure refrigerant of the evaporator is not diffused into the hermetic container. The main focus is to block the compression noise as a baffle device in the muffler to increase the suction efficiency.
일반적으로 밀폐형 압축내의 냉매 가스 흡입 과정에서 흡입 머플러 구조에 따라서 압축기의 효율과 소음이 좌우되는데 종래의 흡입 머플러 구조는 내부에 배플(Baffle)장치 및 흡입구(2a)에 냉매 흡입량을 조절하여 흡입되도록 되었으나 흡입구(2a)로 새어 나오는 압축 소음 감쇄 기능이 약해서 주파수400-500(HZ)영역에서 대체로 압축 소음이 높게 나타나는 결점이 있었고 또한 흡입 머플러의 냉매 흡입 머플러의 냉매 흡입 플로우를 보면 밀폐용기(3F)에 확산된 냉매는 압축기 정지 상태에서 내부 온도가 떨어지게 되고 냉매는 액화되어 용기 하부로 가라 앉으며 하부에 있던 냉동 오일과 혼합되는 문제점이 있었는데 이것은 압축기의 시동을 시작할 때 오일과 냉매가 혼합된 것이이 유입되어 각 밸브 동작이 달라져서 이상 소음이 발생하게 되는 결점이 있었다.In general, the efficiency and noise of the compressor are influenced by the suction muffler structure in the refrigerant gas suction process in the hermetic compression. In the conventional suction muffler structure, the suction amount is adjusted by adjusting the amount of refrigerant suction in the baffle device and the suction port 2a. The compression noise attenuation function leaked to the inlet 2a is weak, and the compression noise is generally high in the frequency 400-500 (HZ) region. Also, the refrigerant suction flow of the refrigerant suction muffler of the suction muffler is shown in the sealed container 3F. The diffused refrigerant has a problem that the internal temperature drops when the compressor is stopped and the refrigerant liquefies, sinks to the bottom of the vessel and mixes with the refrigeration oil at the bottom. This is caused by the mixing of oil and refrigerant at the start of the compressor. There was a drawback that abnormal noise was generated because each valve operation changed. .
본 고안은 상기 종래의 이러한 결점을 해결하고자 흡입 머플러 내부 장치를 바꾸고 냉매 가스 흡입 플로우를 바꿔 성능 향상과 압축 소음을 감쇄하도록 흡입 머플러 구조를 변경한 것으로서 이를 첨부된 도면에 따라서 상세히 설명하면 다음과 같다.The present invention is to change the suction muffler structure to change the internal device of the suction muffler and to change the refrigerant gas suction flow to reduce the performance and to reduce the compression noise in order to solve the above-described drawbacks as described in detail according to the accompanying drawings. .
밀폐용기(1)의 중앙부에 입설시킨 중심축(2)의 외주에 모우터(3)가 설치되고 그 하방에 피스톤(4)을 설치하여 저압실(5)을 형성하고 저압실(5)의 입측인 피스톤(4) 상부에 흡입실(6)과 토출실(7)이 형성된 실린더 헤드(8)의 상부로 양측지지관(9) (9a)과 연설되는 흡입관(10) (10a)의 상단에 배플(Baffle) (11)을 삽지시킨 지지체(12)에 오일드립틈(13)이 형성되어 A실(A)과 B실(B)이 형성되도록 흡입 머플러(14)를 설치한 통상의 것에 있어서 흡입관(10) (10a)상단이 일측 흡입관(10)의 내벽에 소음감쇄 수직격판(15)을 입설시키고 타측 흡입관(10a)의 내벽에는 소음감쇄 수평격판(15a)을 흡입 머플러(14)에 뚫은 관통 구멍(16)의 하단부에 용착하되 관통구멍(14)에는 흡입튜브(17)와 후렉시블 스프링(18)으로 연설된 흡입구(19)가 연통되도록 끼워 붙임 하여서 된 것이다.The motor 3 is installed on the outer periphery of the central shaft 2 placed in the central part of the sealed container 1, and the piston 4 is provided below to form the low pressure chamber 5, and the low pressure chamber 5 The upper end of the suction pipes 10 and 10a which are extended to both the support pipes 9 and 9a above the cylinder head 8 having the suction chamber 6 and the discharge chamber 7 formed on the piston 4 on the inlet side. In the usual case in which the oil drip gap 13 is formed in the support 12 into which the baffle 11 is inserted, and the suction muffler 14 is formed so that the chamber A and the chamber B are formed. In the upper part of the suction pipe (10) (10a) is placed a noise damping vertical plate 15 on the inner wall of one suction pipe 10, and the noise damping horizontal plate (15a) is placed on the inner wall of the other suction pipe (10a) to the suction muffler (14). It is to be welded to the lower end of the through-hole 16, but the through-hole 14 is fitted to the suction tube 17 and the suction port 19, which is addressed to the flexible spring 18 to be in communication.
이와 같이 구성된 본 고안의 작용 효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.
압축기가 정지 상태에 있다가 저온 상태에서 가동이 되면 밀폐 용기(1)하부에 형성된 저압실(5)의 오일과 포합된 액화 상태의 냉매는 거품을 일으키면서 퍼져 올라 가지만 흡입구(19)와 흡입 튜브(17)사이에 틈이 없는 후레시블 스프링(18)이 장설되어 고정된 흡입 튜브(17)와 펌프의 진동으로 후렉시블 스프링(18)이 미세한 틈을 벌리게 되므로 거품 상태로서 상승한 오일은 후렉시블 스프링(18)에 묻히게 되고 냉매가스만이 후레시블스프링(18)사이를 통과하면서 흡입구(19)를 통과하여 머플러(14)의 A실에 저장되게 되며 압축기가 연속적인 운전 상태에서는 냉매가 증발기에서 바로 후렉시블 스프링(18)과 흡입구(19)를 통하여 머플러(14)의 A실로 저장되게 되고 후렉시블 스프링(18)의 미세한 틈사이로 들어온 오일은 종래와 같이 오일 드립틈(13)으로 새어나가게 되고 순수한 냉매만이 머플러 B실에 모여 양측의 흡입관(10) (10a)을 통하여 흡입실(6)로 유입되어 실린더(8)로 흡입되게 되는 것이며 실린더(8)내에서 발생되는 압축 소음은 냉매 흡입 방향의 역순으로 빠져 나가다가 대부분 머플러(14)의 A실과 B실 및 관로에서 감쇄되고 그 잔량이 흡입구(19)를 새어나와 후렉시블 스프링(18)에 투과 되지 못하고 소음의 원인이 약하여 지게 되므로 대부분의 소음을 차단되도록 한 것이다.When the compressor is in a stopped state and operated at a low temperature state, the refrigerant in the liquefied state combined with the oil of the low pressure chamber 5 formed under the sealed container 1 expands while foaming, but the suction port 19 and the suction tube A flexible spring 18 having no gap therebetween is installed, and the flexible spring 18 opens a minute gap due to the vibration of the suction tube 17 and the pump which are fixed. ) And only the refrigerant gas passes between the flexible springs 18 and passes through the inlet port 19 to be stored in the chamber A of the muffler 14. In the continuous operation of the compressor, the refrigerant flows directly from the evaporator to the flexible spring. Through the 18 and the suction port 19 is stored in the chamber A of the muffler 14 and the oil introduced between the minute gap of the flexible spring 18 is leaked into the oil drip gap 13 as in the prior art. Only high pure refrigerant is collected in the muffler chamber B and enters the suction chamber 6 through the suction pipes 10 and 10a on both sides to be sucked into the cylinder 8, and the compression noise generated in the cylinder 8 is a refrigerant. Most of them are exited in the reverse direction of suction and attenuated in chamber A, chamber B and pipe of the muffler 14, and the remaining amount leaks through the suction port 19 and is not transmitted to the flexible spring 18, and the cause of noise is weak. It is to block the noise.
이와 같이 본 고안은 머플러의 내부 구조를 개선하여 냉매 가스 흡입 플로우(plow)를 머플러의 적정 위치에 설치하여 성능의 향상과 압축 소음을 감쇄토록 하였으며 저온 저압인 고농도의 냉매 가스가 밀폐용기로 유입되어 용기내에서 확산됨이 없이 곧바로 흡입관과 흡입 머플러를 통하여 흡입시키게 되므로 동일 배기량으로도 냉동 능력을 향상시킬 수 있는 것이다.As such, the present invention improves the internal structure of the muffler and installs a refrigerant gas suction flow at an appropriate position of the muffler to improve performance and reduce compression noise. Since it is sucked through the suction pipe and the suction muffler without spreading in the container, it is possible to improve the freezing capacity even with the same displacement.
