Abstract

A motor-compressor unit for refrigerators is provided with tubes for feeding the gas from a hermetic container to the cylinder suction chamber. A main tube communiates with the suction chamber by way of a relative silencer, while two supplementary tubes communicate directly with the suction chamber. The configuration and dimensions of the main tube and supplementary tubes are chosen to obtain a degree of noise reduction without reducing the throughput of the induced gas.

본 발명은 냉장고용 모우터-콤프레샤에 관한 것으로, 특히 밀폐용기내에 용입된 냉매가스를 모우터-콤프레샤장치의 실린더 헤드에 형성된 흡입실로 공급하기 위한 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor compressor for a refrigerator, and more particularly, to an apparatus for supplying a refrigerant gas in a sealed container to a suction chamber formed in a cylinder head of a motor compressor device.

종래의 용접 밀폐식 모우터-콤프레샤에서는 밀폐용기내에 함유된 냉매가스를 압축기 실린더 헤드로 공급하기 위해 용기의 내부에서 전술한 흡입실과 연결된 소음기(사이렌샤)에 연결한 오직 하나의 흡입관만이 구비되어 있었다.Conventional welding hermetic motor-compressors are provided with only one suction pipe connected to the silencer (silencer) connected to the suction chamber described above inside the container to supply refrigerant gas contained in the sealed container to the compressor cylinder head. there was.

그러나 모우터-콤프레샤의 동력 즉 냉장능력 혹은 냉동능력이 더 커질 필요가 있을 때는 흡립되는 냉매가스의 양이 증가할 필요가 있는 것이다.However, when the power of the motor-compressor, that is, the refrigeration capacity or the freezing capacity needs to be increased, the amount of refrigerant gas adsorbed needs to be increased.

이때 모우터-콤프레샤의 기본요소들의치수와 형상이 바뀌지 않게 하여 여러가지 동력을 가진 모우터-콤프레샤가 동일한 기본요소러써 제조되어 제조비용을 묶어 두는 것을 가능하게 하는 것은 극히 중요하다.At this time, it is extremely important that the size and shape of the basic elements of the motor-compressor are not changed so that the motor-compressor having various powers can be manufactured using the same basic elements to tie up manufacturing costs.

본 발명은 이러한 문제를 해결하기 위해 제안된 것이다.The present invention has been proposed to solve this problem.

본 발명의 목적은 충분한 양의 냉매가스를 흡입할 수 있도록 하는 동시에 흡입관에서 냉매가스의 맥동운동에 의하여 발생되는 소음을 최소한으로 줄일 수 있도록 하는데 있다.An object of the present invention is to be able to suck a sufficient amount of refrigerant gas and to reduce the noise generated by the pulsation movement of the refrigerant gas in the suction pipe to a minimum.

이와 같은 본 발명의 목적은 냉매가스의 흡입량과, 냉매 가스의 흐름에 의하여 발생된 소음을 줄이기 위한 압력강하가 주흡입관과 보충흡입관 사이에 합리적으로 분배되도록 한 새로운 구조와 배열의 흡입관을 제공하므로서 효과적으로 달성될 수 있다.It is an object of the present invention to effectively provide a suction tube of a new structure and arrangement in which the suction amount of the refrigerant gas and the pressure drop for reducing the noise generated by the flow of the refrigerant gas are reasonably distributed between the main suction pipe and the supplementary suction pipe. Can be achieved.

본 발명의 특징은 냉매가스를 실린더헤드의 흡입실로 공급하는 공급수단인 일측 단부가 밀폐용기의 내부와 연통되고 마측단부는 흡입실에 연결된 소음기와 연통된 주흡입관과, 용기의 내부를 직접 흡입실로 연결하는 보충흡입관으로 구성되고, 이들 주흡입관과 보충흡입관이 상이한 단면부에 의하여 관의 중앙부에 연결된 소경단면의 단과부로 구성됨을 특징으로 한다.The present invention is characterized in that the one end of the supply means for supplying the refrigerant gas to the suction chamber of the cylinder head is in communication with the interior of the sealed container and the end is connected to the main suction pipe communicating with the silencer connected to the suction chamber, the inside of the container directly into the suction chamber Complementary suction pipe to be connected, characterized in that the main suction pipe and the supplementary suction pipe is composed of the end section of the small diameter cross-section connected to the central portion of the tube by different cross-section.

본 발명을 첨부도면에 의거하여 보다 상세히 설명하면 다음과 같다.Referring to the present invention in more detail based on the accompanying drawings as follows.

도면에서, 밀폐용기(10)에 피스턴형의 모우터-콤프레샤 장치(12)가 수용되어 있다. 설명을 간단명료하게 하기 위하여 본 발명의 요지에 관련이 없는 부분에 대하여서는 이를 도시하거나 설명하지 않았으며, 이러한 형태의 모우터-콤프레샤 장치는 통상의 것과 동일하다.In the figure, a piston-type motor-compressor device 12 is accommodated in the sealed container 10. For the sake of simplicity, the parts not related to the gist of the present invention are not shown or described, and this type of motor-compressor device is the same as the conventional one.

흡입 및 배기실(도시하지 않았음)이 형성된 실린더헤드(14)가 모우터-콤프레샤장치(12)의 하측부에 착설되어 있다. 콤프레샤 동체(20)에 볼트(18)로 고정된 소음기(16)는 공지의 방법으로 동체(20)에 착설된 적당한 도관을 통하여 실린더헤드(14)의 흡입실과 연통되어 있다. 주흡입관(22)이 동체(20)에 착설된 삽입공(23)을 통하여 삽입되어 소음기(16)를 용기(10)의 내부에 연결한다. 두 보충흡입관(24), (26)의 단부는 실린더헤드(14)의 상부에 천설된 적당한 두 삽입공으로 삽입되어 용기(10)의 내부가 실린더헤드(14)에 형성된 흡입실로 직접 연결되게 한다. 두 보충흡입관(24), (26)의 두 단부는 경사관부27), (28), (29), (30)와 중앙부보다 직경이 작은 원통형의 단관부(31), (32), (33), (34)로 구성된다.The cylinder head 14 in which the suction and exhaust chambers (not shown) are formed is mounted on the lower side of the motor-compressor apparatus 12. The silencer 16 fixed to the compressor body 20 with bolts 18 is in communication with the suction chamber of the cylinder head 14 via a suitable conduit mounted to the body 20 in a known manner. The main suction pipe 22 is inserted through the insertion hole 23 installed in the body 20 to connect the silencer 16 to the inside of the container 10. The ends of the two supplemental suction tubes 24, 26 are inserted into two suitable insertion holes provided in the upper portion of the cylinder head 14 so that the inside of the container 10 is directly connected to the suction chamber formed in the cylinder head 14. The two ends of the two supplementary suction tubes 24, 26 are inclined tube portions 27, 28, 29, 30 and cylindrical short tube portions 31, 32, 33 having a diameter smaller than the central portion. ), And (34).

마찬가지로 주흡입관(22)의 상측단부도 경사관부(35)와 직경이 작은 원통형의 단관부(36)로 구성된다.Similarly, the upper end of the main suction pipe 22 also includes an inclined pipe part 35 and a cylindrical short pipe part 36 having a small diameter.

보충흡입관(24), (26)의 중앙부는 동일한 길이의 두 부분으로 나누어져 있으며 이들의 축선은 적당한 각도로 상호 경사져 있다. 이들 축선이 이루는 각도는 도시된 바와 같이 약 155°이다. 공급관에 사용된 특별한 배열 즉 소음을 낮추기 위해 단면과 방향을 변화시킨 배열때문에 가스의 맥동흐름에서 나타나는 압력강하는 소음감소와 유입가스량 사이를 적절히 조화시키는 적당한 형상의 보조 흡입관을 사용함에 의해 보상될 수 있다.The central portions of the supplementary suction pipes 24 and 26 are divided into two parts of equal length and their axes are inclined to each other at an appropriate angle. The angle formed by these axes is about 155 ° as shown. Due to the special arrangement used in the supply line, that is, the change in cross section and direction to lower the noise, the pressure drop in the pulsating flow of the gas can be compensated by using an appropriately shaped auxiliary suction line that properly balances the noise reduction with the incoming gas volume. have.

이렇게 구성된 본 발명의 효과는 종래의 모우터-콤프레샤의 동력 즉 냉장능력 혹은 냉동능력이 더 커질 필요가 있을 때 모우터-콤프레샤의 기본요소들의 치수와 형상을 바꾸지 않고도 동일한 기본요소로서 여러가지 동력을 가진 모우터-콤프레샤를 제작할 수 있게 하면서도 소음이 증가하지 않게 하여 경제적인 모우터-콤프레샤 제조가 가능하게 한다.The effects of the present invention configured as described above have various powers as the same basic elements without changing the dimensions and shapes of the basic elements of the motor-compressor when the power of the conventional motor-compressor, that is, the refrigerating or freezing capacity, needs to be increased. The motor-compressor can be manufactured while the noise is not increased, thereby making it possible to manufacture the motor-compressor economically.

각 보충관의 단면변화와 경사진 형상은 가스의 맥동흐름에 영향을 미쳐 맥동흡입의 소음을 줄이게 된다.The cross-sectional change and the inclined shape of each supplementary pipe affects the pulsation flow of the gas to reduce the noise of the pulsation suction.

더구나 각 보충관의 경사진 형상은 관의 자유단인 단관부(31), (32)가 상호 이격되게 배열되어(첨부 도면에서 도시된 바와 같이) 각 보충관이 용기내의 각각 다른 영역에서 냉매가스를 흡입하여 흡입효율을 높게하는 부가적 효과가 있다.Furthermore, the inclined shape of each supplementary tube is arranged so that the free end of the tube 31, 32 are spaced apart from each other (as shown in the accompanying drawings) so that each supplementary tube is in a different region in the container. There is an additional effect of increasing the suction efficiency by inhaling.
