Sectional drawing which shows the combined state of an assembly and a suction silencer.
제1도 내지 제3도에서 밀폐형 전동 압축기의 동작은 쉘(2)내부에 전기적에너지를 기계적에너지로 바꾸어 주는 전동기구부와 진동기구부의 전동력을 받아 냉매를 압축하는 압축기구부로 구분한다.The operations of the hermetic electric compressor in FIGS. 1 to 3 are divided into an electric mechanism part for converting electrical energy into mechanical energy in the shell 2 and a compressor mechanism part for compressing a refrigerant by electric power of the vibration mechanism part.
상기 전동기구부와 압축기구부의 동작은, 밀봉단자를 통해 외부전원이 고정자 에 인가되면 고정자(3)내부에 위치한 회전자(4)가 회전하여 기계적에너지를 생성하게 된다.In the operation of the electric mechanism and the compression mechanism, when an external power source is applied to the stator through the sealing terminal, the rotor 4 located inside the stator 3 rotates to generate mechanical energy.
상기 회전자(4)의 회전에너지는 회전자(4)와 결합되어 있는 크랭크축(5)으로 전달되며, 이에 따라 크랭크축(5)은 회전운동을 수행하게 된다.The rotational energy of the rotor 4 is transmitted to the crankshaft 5 coupled with the rotor 4, whereby the crankshaft 5 performs a rotational movement.
실린더(6) 공간내의 냉매유입과정을 설명하면, 싸이클을 돌아서 압축기(1)로 들어온 냉매는 실린더(6)내의 피스톤의 후퇴에 의해 플라스틱 흡입소음기(7)를 통해 흡입밸브를 열고 실린더(6) 내부로 들어온다.When the refrigerant flow in the cylinder 6 space is explained, the refrigerant entering the compressor 1 by turning the cycle opens the suction valve through the plastic suction silencer 7 by the retraction of the piston in the cylinder 6, and the cylinder 6 Come inside
유입된 냉매는 피스톤의 전진으로 압축되며 압축냉매는 일정압 이상이 되면 토출밸브를 열고 토출체적으로 토출되며 토출체적을 통한 압축 냉매가스는 토출소음기(8)를 통하고 상기 토출소음기와 연결된 루우프파이프(9)를 지나서 냉각싸이클로 배출하게된다.The introduced refrigerant is compressed by the forward of the piston, and when the compressed refrigerant is above a certain pressure, the discharge valve is opened and discharged into the discharge volume. The compressed refrigerant gas through the discharge volume passes through the discharge silencer 8 and is connected to the loop pipe connected to the discharge silencer. It passes over (9) to the cooling cycle.
이와 같이, 상기의 과정에서 본 고안과 관련있는 흡입소음기(3)는, 제2도 내지 제3도에서 보인 바와 같이, 헤드커버(12)의 일측에 설치되며, 헤드커버 어셈블리(11)의 적정한 위치에 흡입소음기(7)의 결합돌기부(7-1)와 결합하는 결합구멍(12-1)이 설치되어 있다.As such, the suction silencer 3 related to the present invention in the above process is installed at one side of the head cover 12, as shown in FIGS. A coupling hole 12-1 which engages with the engaging projection 7-1 of the suction silencer 7 is provided at the position.
상기 흡입소음기(7)의 결합돌기부(7-1)와 해드커버(12)의 결합구멍(12-1)을 억지 압입하여 가조립시킨후, 헤드커버 볼트(17)와 클램프(16)에 의해 흡입소음기를 헤드커버에 고정시킨다.After press-fitting and assembling the coupling protrusion 7-1 of the suction silencer 7 and the coupling hole 12-1 of the head cover 12, the suction is carried out by the head cover bolt 17 and the clamp 16. Fix the muffler to the head cover.
그 후, 압축기본체(1)에 결합시켜 압축기(1)를 작동하게 되면 냉매는 흡입소음기(7)를 통하여 냉매가 흡입되어 실린더(7)내부로 들어가 압축되어 토출하게 된다.Thereafter, when the compressor 1 is operated by being coupled to the compressor main body 1, the refrigerant is sucked through the suction silencer 7 and enters the cylinder 7 to be compressed and discharged.
그러나, 종래의 기술에 의한 밀폐형 압축기의 흡입소음기 고정장치는 흡입소음기와 헤드커버의 억지 압입 가조립을 위해 결합돌기부와 결합구멍을 형성함에 있어, 공차관리의 어려움이 따른다. 만약, 결합돌기부가 결합구멍 보다 직경이 크면 흡입소음기가 버어(Burr)를 발생하고, 그반대로 결합구멍이 크게 되면 흡입소음기가 결합되지 못하고 탈락되는 현상이 발생하게 된다.However, the suction silencer fixing device of the hermetic compressor according to the related art has a difficulty in managing tolerances in forming the coupling protrusion and the coupling hole for assembling the press fit of the suction silencer and the head cover. If the coupling protrusion is larger in diameter than the coupling hole, the suction silencer generates a burr. On the contrary, if the coupling hole is large, the suction silencer cannot be coupled and is dropped.
그리고 상기의 가조립된 흡입소음기와 헤드커버 어셈블리는 클램프(16)와 헤드커버 볼트(17)에 의해 고정되므로, 시간과 인원이 필요하게 되어 제품에 대한 비용이 상승하는 결과를 초래하게 되는 문제점이 있는 바, 본 고안의 목적은 상기와 같은 문제점을 고려하여 안출한 것으로, 흡입소음기와 헤드커버 어셈블리를 쉽게 결합하면서 이탈하지 않도록 한 밀폐형 압축기의 흡입소음기 고정장치를 제공함에 있다.In addition, the preassembled suction silencer and the head cover assembly are fixed by the clamp 16 and the head cover bolt 17, which requires time and personnel, resulting in an increase in the cost of the product. It is an object of the present invention to provide a suction silencer fixing device of the hermetic compressor to avoid detachment while easily combining the suction silencer and the head cover assembly.

이러한, 본 고안의 목적은 헤드커버의 결합구멍을 결합돌기부보다 조금크게 형성하고 흡입소음기의 일측에 헤드커버와 결합되도록 한 걸림후크를 형성함으로써 달성된다.This, the object of the present invention is achieved by forming the engaging hook of the head cover slightly larger than the engaging projection and forming a hook hook to be coupled to the head cover on one side of the suction silencer.
이하, 본 고안에 의한 밀폐형 압축기의 흡입소음기 고정장치를 첨부도면에 의하여 설명하면 다음과 같다.Hereinafter, the suction silencer fixing device of the hermetic compressor according to the present invention will be described with reference to the accompanying drawings.
제4도는 본 고안의 헤드커버 어셈블리와 흡입소음기의 결합상태를 나타내는 단면도이고, 제5도는 본 고안의 흡입소음기의 걸림후크가 헤드커버에 걸려 있는 상태를 보인 상세 단면도를 각각 보인 것이다.Figure 4 is a cross-sectional view showing a coupling state of the head cover assembly and the suction silencer of the present invention, Figure 5 shows a detailed cross-sectional view showing a state that the hook hook of the suction silencer of the present invention is caught on the head cover.
이에 도시한 바와 같이, 본 고안에 의한 밀폐형 압축기의 흡입소음기 고정장치는, 흡입소음기의 일측에 형성한 결합돌기부(20-1)와, 그 결합돌기부와 삽입되도록 헤드커버 어셈블리에 형성한 결합구멍(21-1)과, 상기 흡입소음기의 타측에 형성하여 헤드커버와 결합되도록 한 걸림후크(20-2)로 구성된다.As shown in the drawing, the suction silencer fixing device of the hermetic compressor according to the present invention includes a coupling protrusion 20-1 formed on one side of the suction silencer, and a coupling hole formed in the head cover assembly to be inserted into the coupling protrusion ( 21-1) and a hook hook 20-2 formed on the other side of the suction silencer to be coupled to the head cover.
상기 흡입소음기(20)의 결합돌기부(20-1)를 헤드커버(21)의 결합구멍(21-1)에 결합할 때, 헤드커버(21)의 결합구멍(21-1)을 흡입소음기(20)의 결합돌기부(20-1) 직경보다 약간 크게 형성하여 결합이 용이하도록 한다.When the coupling protrusion 20-1 of the suction silencer 20 is coupled to the coupling hole 21-1 of the head cover 21, the coupling hole 21-1 of the head cover 21 is connected to the suction silencer ( Forming slightly larger than the diameter of the coupling protrusion 20-1 of 20) to facilitate the coupling.
도면중 미설명 부호 22는 토출체적을 나타낸다.In the figure, reference numeral 22 denotes a discharge volume.
상기와 같이 구성되는 본 고안에 의한 밀폐형 압축기의 흡입소음기 고정장치의 작용을 설명하면 다음과 같다.Referring to the operation of the suction silencer fixing device of the hermetic compressor according to the present invention configured as described above are as follows.
종래는 흡입소음기의 결합돌기부와 헤드커버의 결합구멍을 프레스기로 억지 압입하여 가조립시키는 과정에서 결합돌기부가 결합구멍 보다 직경이 크면 흡입소음기가 버어(Burr)를 발생하고, 그 반대로 결합구멍이 크게 되면 흡입 소음기가 결합되지 못하고 탈락되는 현상이 발생하므로, 본 고안은 상기 헤드커버 어셈블리의 헤드커버(21)에 결합구멍(21-1)을 결합시 결합돌기부(20-1) 직경보다 약간 여유 있게 형성하고, 흡입소음기(20)의 일측에 헤드커버(21)단면에 삽입하여 결합할 수 있는 걸림후크(20-2)를 형성하면, 상기 흡입소음기(20)가 헤드커버 어셈블리(23)에 결합시 어렵지 않게 결합할 수 있고 또한, 흡입소음기(20)의 걸림후크(20-2)가 헤드커버(21)에 체결되어 쉽게 헤드커버 어셈블리(23)로부터 이탈을 방지할 수 있는 효과를 가져와 별도의 고정부품없이 결합이 가능하도록 하였다.Conventionally, in the process of forcibly press-fitting the coupling protrusion of the suction silencer and the coupling hole of the head cover with a press machine, if the coupling protrusion is larger in diameter than the coupling hole, the suction silencer generates a burr and vice versa. Since the phenomenon that the suction silencer is not coupled and the dropout occurs, the present invention is formed with a margin slightly larger than the diameter of the coupling protrusion 20-1 when coupling the coupling hole 21-1 to the head cover 21 of the head cover assembly. And, if one side of the suction silencer 20 to form a hook hook (20-2) that can be inserted into the cross section of the head cover 21, when the suction silencer 20 is coupled to the head cover assembly (23) It is not difficult to combine, and the hook hook 20-2 of the intake silencer 20 is fastened to the head cover 21, so that the effect of preventing the detachment from the head cover assembly 23 can be easily fixed. No parts This combination was made possible.
이상에서 설명한 바와 같이, 본 고안에 의한 밀폐형 압축기의 흡입소음기 고정장치는, 흡입소음기의 일측면에 원형에 가까운 걸고리를 형성하여 헤드커버의 일측면에 체결함으로서, 헤드커버 어셈블리에 흡입소음기를 결합시 별도의 억지 압입공정을 배제하여 작업성이 향상되고, 제품에 대한 코스트를 낮출 수 있다.As described above, the suction silencer fixing device of the hermetic compressor according to the present invention forms a hook near the circular shape on one side of the suction silencer and fastens it to one side of the head cover, thereby coupling the suction silencer to the head cover assembly. By eliminating the separate indentation process, workability can be improved and the cost for the product can be lowered.
