Description
본 발명은 밀폐형 압축기에 관한 것으로서, 특히 흡입밸브의 진동을 줄이고, 밸브타격에 의한 압축기의 소음을 저감시키도록 한 밀폐형 압축기의 흡입밸브구조에 관한 것이다.The present invention relates to a hermetic compressor, and more particularly, to an intake valve structure of a hermetic compressor which reduces vibration of the intake valve and reduces noise of the compressor due to a valve strike.
종래 밀폐형 압축기는 제1도 및 제2도에 도시된 바와 같이, 하부밀폐용기(1b)와 상부밀폐용기(1a)로 이루어진 밀폐용기(1)내에 냉매가스를 압축하는 압축기구부와, 상기 압축기구부를 구동하는 전동기구부로 구성하였다.Conventional hermetic compressors, as shown in Figures 1 and 2, the compression mechanism for compressing the refrigerant gas in the closed container (1) consisting of the lower hermetic container (1b) and the upper hermetic container (1a), and the compression mechanism It consists of a power mechanism unit for driving.
상기 전동기구부는 전원이 인가되면 자력을 발생하도록 프레임(2)에 볼트로 체결된 고성자(3)와, 상기 고성자(3)의 자력에 의해 회전하는 의전자(4)와, 상기 회전자(4)와 같이 회전하도록 회전자(4)에 암입된 크랭크축(5)으로 구성하였다.The electric machine part is a high magnet (3) fastened by bolts to the frame (2) to generate a magnetic force when the power is applied, the electronics (4) rotated by the magnetic force of the high magnet 3 and the rotor It consisted of the crankshaft 5 embedded in the rotor 4 so that it might rotate like (4).
상기 압축기구부는 크랭크축(5) 상부에 편심되어 일체로 형성된 편심부(6)와, 상기 편심부(6)의 외주에 형성되어 크랭크축(5)의 회전운동을 왕복운동으로 바꾸어 주는 슬라이더(7)와, 상기 슬라이더(7)가 삽입된 상태로 설치되어 크랭크축(5)의 회전에 따라 왕복운동하는 피스톤(8)과, 상기 피스톤(8)이 왕복운동을 할 수 있도록 프레임(2)에 볼트로 체결되어진 실린더(9)와, 상기 실린더(9)내에 형성된 압축실(10)과, 상기 압축실(10)로 유입되는 냉매가스의 흡입을 개폐하는 흡입밸브(11)와, 상기 흡입밸브(l1)를 통해 흡입된 냉매가스의 누설을 방지하는 헤드(12)와, 상기 압축실(10)로부터 압축된 냉매가스의 토출을 개폐하는 토출밸브(13)와, 상기 토출밸브(13)로부터 토출되는 냉매가스의 누설을 방지하는 패킹카바(14)와, 상기 실린더(9) 전체를 덮고 있는 헤드카바(15)로 구성하였다.The compressor mechanism is an eccentric portion 6 which is formed eccentrically on the crankshaft 5 and integrally formed on the outer periphery of the eccentric portion 6, and a slider for converting the rotational movement of the crankshaft 5 into a reciprocating motion ( 7), the piston (8) installed with the slider (7) inserted and reciprocating in accordance with the rotation of the crankshaft (5), and the frame (2) to allow the piston (8) to reciprocate A cylinder 9 fastened by bolts, a compression chamber 10 formed in the cylinder 9, a suction valve 11 for opening and closing the suction of refrigerant gas flowing into the compression chamber 10, and the suction A head 12 for preventing leakage of the refrigerant gas sucked through the valve 11, a discharge valve 13 for opening and closing the discharge of the refrigerant gas compressed from the compression chamber 10, and the discharge valve 13. A packing cover 14 for preventing leakage of refrigerant gas discharged from the air, and a head cover 15 covering the entire cylinder 9. ).
이와 같이 구성된 종래의 밀폐형 압축기에 전원이 인가되면 고정자(3)와 회전자(4) 사이에 유도전류가 발생하여 회전자(4)가 회전하게 되고, 회전자(4)의 회전에 따라 회전자(4)에 압입된 크랭크축(5)이 회전자(4)와 같이 회전하게 된다.When power is applied to the conventional hermetic compressor configured as described above, an induction current is generated between the stator 3 and the rotor 4 so that the rotor 4 rotates, and the rotor according to the rotation of the rotor 4. The crankshaft 5 pressed into (4) rotates like the rotor 4.
이때, 상기 크랭크축(5)의 상부에 형성된 슬라이더(7)는 크랭크축(5)의 회전운동을 왕복운동으로 전환시키고, 상기 슬라이더(7)가 삽입된 피스톤(8)은 그 운동량을 받아 실린더(9)내에 형성된 압축실(10)내를 왕복운동한다.At this time, the slider 7 formed on the upper part of the crankshaft 5 converts the rotational movement of the crankshaft 5 into reciprocating motion, and the piston 8 into which the slider 7 is inserted receives the momentum of the cylinder. The inside of the compression chamber 10 formed in (9) is reciprocated.
상기 피스톤(8)이 실린더(9)내를 왕복운동하는 데 있어서, 피스톤(8)이 후진운동하는 경우(흡입행정), 상기 밀폐용기(1)내에 설치된 흡입관(도면상에는 미기재)을 통하여 저온저압의 냉매가스가 밀폐용기(1)내로 유입되고, 상기 밀폐용기(1)내로 유입된 저온저압의 냉매가스는 헤드(12)롤 거쳐 흡입밸브(11)를 열고 압축실(10)내로 유입된다.When the piston 8 reciprocates in the cylinder 9, when the piston 8 moves backward (suction stroke), the low temperature low pressure is provided through a suction pipe (not shown in the drawing) provided in the sealed container 1. Refrigerant gas is introduced into the hermetic container (1), the refrigerant gas of low temperature and low pressure introduced into the hermetic container (1) is introduced into the compression chamber (10) by opening the suction valve (11) through the head (12).
상기 압축실(10)내로 유입된 저온저압의 냉매가스는 피스톤(8)이 실린더(9)내에서 후진운동을 끝내고 전진운동을 시작하면(압축행성) 상기 흡입밸브(11)를 닫고 압축실(10)내에서 고온고압의 냉매가스로 압축된다.The refrigerant gas of low temperature and low pressure introduced into the compression chamber 10 closes the suction valve 11 when the piston 8 finishes the backward movement in the cylinder 9 and starts the forward movement. 10) Compressed into a refrigerant gas of high temperature and high pressure.
상기 압축실(10)내에서 고온고압으로 압축되는 냉매가스는 일정압력에 도달하면 토출밸브(13)를 열고 냉매사이클의 응축기로 토출된다.When the refrigerant gas compressed at high temperature and high pressure in the compression chamber 10 reaches a predetermined pressure, the refrigerant gas is opened and discharged to the condenser of the refrigerant cycle.
그러나 이러한 종래 밀폐형 압축기는 제2도와 같이 흡입밸브의 개폐높이를 제한하는 장치가 설치되어 있지 않으므로 흡입행정동안 밸브가 여러차례 개폐되고, 열림 높이도 크기 때문에 흡입밸브가 개폐되면서 헤드에 강하게 부딪히게 되어 소음이 증가하는 문제점이 있었다.However, since the conventional hermetic compressor does not have a device for limiting the opening and closing height of the suction valve as shown in FIG. 2, the valve is opened and closed several times during the suction stroke, and the opening height is also large, so that the suction valve is opened and closed and hits the head strongly. There was an increasing problem.
본 발명은 이러한 점을 감안하여 실린더 상면에 체결홈을 형성하고, 상기 실린더의 체결홈에 흡입밸브스프링을 설치하고, 그 위에 흡입밸브를 결힙함으로써 흡입밸브의 개폐횟수 및 개폐높이를 제한하여 홈입밸브와 헤드의 부딪함으로 인해 발생하는 소음을 저감시키는 데 그 목적이 있다.In view of this, the present invention forms a fastening groove in the upper surface of the cylinder, installs a suction valve spring in the fastening groove of the cylinder, and restricts the number of opening and closing heights of the suction valve by opening the suction valve thereon, thereby limiting the groove inlet valve. The purpose is to reduce the noise caused by the impact of the head and the head.

이하, 본 발명을 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제3도는 본 발명에 의한 밀폐형 압축기의 흡입밸브 구성도를 나타낸 것으로서, 냉매가스를 흡입, 압축, 토출하는 실린더(101)와, 상기 실린더(101)로 흡입되는 냉매가스의 흡입을 개폐하는 흡입밸브(102)와, 상기 흡입밸브(l02)를 통해 흡입된 냉매가스의 유실을 방지하는 패킹카바(103)로 구성된다.3 is a configuration diagram of a suction valve of a hermetic compressor according to the present invention, and includes a cylinder 101 which sucks, compresses and discharges refrigerant gas, and a suction valve that opens and closes suction of refrigerant gas sucked into the cylinder 101. And a packing cover 103 for preventing the loss of the refrigerant gas sucked through the suction valve 110.
그리고 상기 실린더(101) 상면에는 체결홈(104)이 형성되고, 상기 실린더(101)의 체결홈(104)에 흡입밸브스프링(105)이 설치되며, 그 위에 흡입밸브(102)가 결합된다.And a fastening groove 104 is formed on the upper surface of the cylinder 101, the suction valve spring 105 is installed in the fastening groove 104 of the cylinder 101, the suction valve 102 is coupled thereon.
상기 흡입밸브스프링(105)의 한쪽단은 핀에 끼워질수 있도록 결합홀(106)이 형성되고, 다른 한쪽단은 작동시 실린더와 이탈되지 않도록 길게 형성된다.One end of the suction valve spring 105 is formed with a coupling hole 106 to be fitted to the pin, the other end is formed long so as not to be separated from the cylinder during operation.
이와같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.
먼저, 밀폐형 압축기에 전원이 인가되면 전동기구부의 작용에 의해 냉매가스가 흡입밸브(102)를 열고 실린더(101) 내부로 흡입된다.First, when power is applied to the hermetic compressor, the refrigerant gas is sucked into the cylinder 101 by opening the suction valve 102 by the action of the electric mechanism part.
이때, 냉매가스의 흡입을 개폐하는 흡입밸브(l02)는 실린더(101) 상면의 체결홈(104)에 설치된 흡입밸브스프링(105)에 의해 개폐횟수 및 개폐높이가 제한되므로 헤드(도면상에 도시되지 않음)와의 부딪히는 횟수가 현저히 감소하게 되고, 부딪히는 강도도 약해지게 되어 압축기의 소음이 크게 감소되는 것이다.At this time, the intake valve (l02) for opening and closing the suction of the refrigerant gas is limited by the intake valve spring 105 installed in the fastening groove 104 of the upper surface of the cylinder 101, and the opening and closing height is limited because the head (shown in the drawing The number of hits) is significantly reduced, and the strength of the hits is also weakened, which greatly reduces the noise of the compressor.
이상에서 설명한 바와 같이 본 발명은 흡입밸브와 실린더 사이에 흡입밸브의 개폐횟수 및 개폐높이를 제한하는 흡입밸브스프링을 설치하여 흡입밸브와 헤드의 부딪힘을 줄이게 돠므로 압축기의 소음이 크게 감소하는 효과가 있다.As described above, the present invention reduces the collision between the suction valve and the head by installing a suction valve spring that limits the number of opening and closing times and the opening and closing height of the suction valve between the suction valve and the cylinder, thereby greatly reducing the noise of the compressor. have.
