본 고안은 밀폐형 압축기의 머플러 고정장치에 관한 것으로 특히, 헤드커버와 머플러 틈새로 오일이 스며드는 것을 막고 머플러에 의한 소음을 막도록 한 것이다.The present invention relates to a muffler fixing device of a hermetic compressor, in particular, to prevent oil from seeping into the gap between the head cover and the muffler and to prevent noise by the muffler.
종래 밀폐형 압축기의 머플러 고정장치와 그 주변부는 제1도에 도시된 바와 같이 다른 장치에서 유입되는 냉매의 재팽창을 막는 플라스틱 머플러(1)와 상기 머플러(1)에서 유출된 냉매가 압축기로 가는 동안 경유하는 압축기의 헤드커버(2)로 구성되었다.The muffler fixing device and its periphery of the conventional hermetic compressor are shown in FIG. 1 while the plastic muffler 1 and the refrigerant flowing out of the muffler 1 which prevent the re-expansion of the refrigerant flowing from the other device go to the compressor It consists of the head cover 2 of the compressor via.
그리고, 상기 플라스틱 머플러(1)를 상기 헤드커버(2)에 고정시키기 위한 머플러 홀더(3)와 보울트(4)로 구성되었다.The muffler holder 3 and the bolt 4 for fixing the plastic muffler 1 to the head cover 2 are formed.
이상과 같은 구성을 가지는 종래 고안의 문제점은 다음과 같다.Problems of the conventional design having the above configuration is as follows.
헤드커버(2)에 머플러(1)를 고정하는 것을 머플러 홀더(3)와 보울트(4)를 이용할 경우에는 플라스틱 머플러(1)의 좌우에서 간접적으로 체결하므로 상기 플라스틱 머플러(1)와 헤드커버(2) 사이의 틈새로 비산되는 오일이 스며들 수 있게 된다.In the case of using the muffler holder 3 and the bolt 4 to fix the muffler 1 to the head cover 2 indirectly from the left and right of the plastic muffler 1, the plastic muffler 1 and the head cover ( 2) The oil splashed into the gap between them will be able to seep.
그로 인해 흡입효율이 떨어지게 되어 압축기의 성능이 저하된다.As a result, the suction efficiency is lowered and the performance of the compressor is lowered.
또한, 간접체결이므로 플라스틱 머플러(1)가 압축기 운전중에 떨리는 것을 방지하기 어렵게 되어 소음을 증가시키게 된다.In addition, the indirect fastening makes it difficult to prevent the plastic muffler 1 from shaking during operation of the compressor, thereby increasing noise.
이 경우 머플러 홀더(3)와 머플러(1)의 사이에 고무를 넣고 체결하는 방법이 있지만 이렇게 할 경우 조립성을 떨어뜨리게 된다.In this case, there is a method of inserting rubber between the muffler holder 3 and the muffler 1, but in this case, the assemblability is deteriorated.
본 고안은 이러한 종래 기술의 문제점을 해결하기 위한 것으로 압축기의 헤드커버에 플라스틱 머플러를 직접 체결함으로써 헤드커버와 머플러 틈새로 오일이 스며드는 것을 막고 플라스틱 머플러에 의한 소음을 막는데 목적이 있다.The present invention is to solve the problems of the prior art is to prevent the oil infiltrating into the gap between the head cover and the muffler by directly fastening the plastic muffler to the head cover of the compressor and to prevent noise by the plastic muffler.
본 고안 밀폐형 압축기의 머플러 고정장치를 제2도 및 제3도에 의하여 설명하면 다음과 같다.The muffler fixing device of the present invention hermetic compressor will be described with reference to FIGS. 2 and 3 as follows.
헤드커버(102)와 머플러(101)의 틈새로 오일이 스며드는 것을 막고 플라스틱 머플러에서 발생되는 소음을 막기 위해 머플러(101)를 헤드커버(102)에 직접 체결하는 체결수단과, 상기 체결수단내로 냉매가 유동할 수 있도록 유동수단을 구비하였다.Fastening means for fastening the muffler 101 directly to the head cover 102 to prevent oil from seeping into the gap between the head cover 102 and the muffler 101 and to prevent noise generated from the plastic muffler, and refrigerant into the fastening means. It was equipped with a flow means to flow.
그리고, 상기 체결수단은 고정볼트(103)와, 상기 고정볼트(103)가 머플러(101)에 형성된 체결구멍에 삽입되어 헤드커버에 나사결합이 되도록 헤드커버(102) 내에 너트부(104)를 구비하였다.In addition, the fastening means has a nut 104 in the head cover 102 so that the fixing bolt 103 and the fixing bolt 103 is inserted into the fastening hole formed in the muffler 101 to be screwed to the head cover. Equipped.
그리고, 상기 유동수단은 고정볼트(103) 내를 통과하여 냉매가 유동하도록 고정볼트(103)에 중공을 구비하였다.In addition, the flow means is provided with a hollow in the fixing bolt 103 so that the refrigerant flows through the fixing bolt 103.
이상과 같은 구성을 가지는 본 고안 밀폐형 압축기의 머플러 고정장치에 대한 구체적인 동작설명과 이에 따르는 효과를 설명한다.A detailed operation of the muffler fixing device of the present invention hermetic compressor having the configuration as described above and the effects thereof will be described.
제3도에 보여지는 바와 같이 고정볼트(103)는 플라스틱 머플러(101)로 부터 들어오는 냉매가 헤드커버(102)를 경유하여 압축기로 유입되도록 중공이 구성되었다.As shown in FIG. 3, the fixing bolt 103 has a hollow structure such that the refrigerant coming from the plastic muffler 101 flows into the compressor via the head cover 102.
상기와 같은 고정볼트(103)가 상기 플라스틱 머플러(101)의 일부분으로 구성되면서 상기 헤드커버(102)의 너트부(104)에 직접체결되므로 머플러(101)와 헤드커버(102)는 기밀을 유지하며 단단히 고정된다.As the fixing bolt 103 is configured as a part of the plastic muffler 101 and directly fastened to the nut part 104 of the head cover 102, the muffler 101 and the head cover 102 maintain airtightness. It is firmly fixed.
따라서, 헤드커버(102)와 머플러(101)의 틈새로 오일이 스며드는 것을 막는다.Therefore, oil is prevented from penetrating into the gap between the head cover 102 and the muffler 101.
또한, 플라스틱 머플러(101)가 압축기 운전중에 떨리지 않으므로 소음절감 효과를 가져올 수 있다.In addition, since the plastic muffler 101 does not tremble during the operation of the compressor, it can bring about a noise reduction effect.
