Description

밀폐형 회전압축기의 토출밸브구조체Discharge valve structure of hermetic rotary compressor

본 고안은 밀폐형 회전압축기의 토출밸브구조체에 관한 것으로서, 더욱 상세하게는 냉매 압축시 간극체적을 최소화함으로써 압축효율을 향상시킬 수 있는 밀폐형 회전압축기의 토출밸브구조체에 관한 것이다.The present invention relates to a discharge valve structure of the hermetic rotary compressor, and more particularly, to a discharge valve structure of the hermetic rotary compressor to improve the compression efficiency by minimizing the gap volume during refrigerant compression.

일반적인 밀폐형 회전압축기는 증기상태의 냉매를 고온.고압으로 압축하는 장치로서, 몸체의 외부에 부설된 어큐뮬레이터(10)를 통해 실린더(20)에 냉매가 흡입되면, 이를 고속으로 구동하는 압축로울러(30)에 의해 압축한 후 상기 실린더(20)의 상면에 결합된 상부플랜지(40)의 토출구멍를 통하여 고압의 냉매를 실린더(20) 외측으로 토출한다.A general hermetic rotary compressor is a device for compressing a refrigerant in a vapor state at a high temperature and high pressure. When a refrigerant is sucked into a cylinder 20 through an accumulator 10 installed outside of a body, a compression roller 30 drives the high speed thereof. After the compression by a) through the discharge hole of the upper flange 40 coupled to the upper surface of the cylinder 20 to discharge the high-pressure refrigerant to the outside of the cylinder (20).

종래의 토출밸브구조체는 도 2에 나타낸 바와 같이, 상부플랜지(40)의 일측에 형성된 토출구멍(41)의 상부를 덮는 토출밸브(42)와, 이 토출밸브의 움직임을 제어하기 위한 밸브벡커(43)와, 이 밸브벡커와 토출밸브의 일측을 관통하며 상부플랜지(40)의 상면에 고정 설치되는 볼트(41)로 구성된다.As shown in FIG. 2, the conventional discharge valve structure includes a discharge valve 42 covering an upper portion of the discharge hole 41 formed at one side of the upper flange 40, and a valve backer for controlling the movement of the discharge valve. 43) and a bolt 41 which penetrates one side of the valve backer and the discharge valve and is fixed to the upper surface of the upper flange 40.

상기와 같이 구성된 토출밸브체는, 회전축이 회전함에 따라 압축로울러가 실린더 내벽을 따라 회전하게 되는데, 이때 흡입구를 통해 압축실로 들어온 가스가 일정 압력에 도달하면 그 압력으로 밸브가 열리고 토출구멍를 통해 가스가 빠져나가도록 되어 있다.In the discharge valve structure configured as described above, as the rotating shaft rotates, the compression roller rotates along the inner wall of the cylinder. At this time, when the gas entering the compression chamber through the suction port reaches a predetermined pressure, the valve opens at that pressure and the gas flows through the discharge hole. It is supposed to exit.

그러나, 압축된 냉매의 토출시 가스의 압력이 떨어지면 밸브의 자체탄성에 의해 토출구멍이 폐쇄되는데, 이때 미처 토출되지 못한 간극 체적(C1) 중의 고온.고압의 가스가 로울러의 회전에 따라 실린더 내부의 압축실로 팽창하여 재팽창 손실이 발생되며 이러한 손실은 압축기의 가장 큰 손실을 차지한다.However, when the pressure of the gas drops during the discharge of the compressed refrigerant, the discharge hole is closed by the self-elasticity of the valve. Expansion into the compression chamber results in reexpansion losses, which account for the largest loss of the compressor.

본 고안은 상기와 같은 문제점을 감안하여 안출한 것으로서, 실린더의 간극체적을 최소화하여 압축효율을 향상시킬 수 있는 밀폐형 회전압축기의 토출밸브구조체를 제공하는 것을 그 목적으로 한다.The present invention has been made in view of the above problems, and aims to provide a discharge valve structure of a hermetic rotary compressor that can improve the compression efficiency by minimizing the gap volume of the cylinder.

이와 같은 목적을 달성하기 위해 본 고안은, 토출구 하부 일측에 경사면으로 이루어진 개방된 공간부를 포함한 상부플랜지와, 밸브구멍을 포함한 토출밸브지지판과, 상기 상부플랜지와 토출밸브지지판 사이에 개재되는 토출밸브판에 일측단은 부착되고 타측단은 상기 밸브구멍으로부터 토출되는 냉매의 압력에 의해 유동가능한 개폐막으로 이루어진 개폐부를 포함한 토출밸브판으로 구성되는 것을 특징으로 한다.In order to achieve the above object, the present invention provides an upper flange including an open space formed of an inclined surface on one side of a lower discharge port, a discharge valve support plate including a valve hole, and a discharge valve plate interposed between the upper flange and the discharge valve support plate. One end is attached to the other end is characterized in that consisting of the discharge valve plate including an opening and closing portion made of an opening and closing membrane flowable by the pressure of the refrigerant discharged from the valve hole.

이하, 본 고안의 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, an embodiment of the present invention in detail as follows.

본 고안 밀폐형 회전압축기는, 도 3에 나타낸 바와 같이, 토출구(51) 하부 일측에 개방공간부를 형성하도록 경사면(52)으로 이루어진 상부플랜지(50)와, 밸브구멍(71)을 포함한 토출밸브지지판(70)과, 상기 상부플랜지(50)와 토출밸브지지판(70) 사이에 개재되는 토출밸브판(60)에 일측단은 부착되고 타측단은 상기 밸브구멍(71)으로부터 토출되는 냉매의 압력에 의해 유동가능한 개폐막(62)으로 이루어진 개폐부(61)를 포함한 토출밸브판(60)으로 구성된다.As the sealed rotary compressor of the present invention, as shown in Figure 3, the discharge valve support plate including the upper flange 50 consisting of the inclined surface 52 and the valve hole 71 to form an open space portion on the lower side of the discharge port 51 ( 70 and one end is attached to the discharge valve plate 60 interposed between the upper flange 50 and the discharge valve support plate 70 and the other end is caused by the pressure of the refrigerant discharged from the valve hole 71. It is composed of a discharge valve plate 60 including an opening and closing portion 61 made of a movable opening and closing membrane 62.

이때, 상기 상부플랜지(50)의 경사면(52)과 토출밸브지지판(70)의 밸브구멍(71) 사이에 상기 토출밸브판(60)의 개폐막(62)이 위치되도록 조립한다.At this time, the opening and closing membrane 62 of the discharge valve plate 60 is assembled between the inclined surface 52 of the upper flange 50 and the valve hole 71 of the discharge valve support plate 70.

상기 개폐부(61)의 개폐막(62)은, 하방향에 위치한 밸브구멍(71)과 상응한 원형으로 형성되며 이 개폐막의 넓이는 상기 밸브구멍의 단면 넓이보다 크게 형성된다.The opening and closing membrane 62 of the opening and closing portion 61 is formed in a circular shape corresponding to the valve hole 71 located in the downward direction, and the width of the opening and closing membrane is formed larger than the cross-sectional area of the valve hole.

상부플랜지(50) 하면에 형성된 상기 경사면(52)은, 도 3b에 나타낸 바와 같이, 상부플랜지(50)를 관통한 토출구(51)의 저면 일측에 개방된 공간부를 형성하여, 냉매흐름의 통로를 제공함과 동시에 냉매의 압축에 의해 개방되는 개폐부(61)의 개폐막(62)의 상향 움직임을 제어하도록 한 것이다.As shown in FIG. 3B, the inclined surface 52 formed on the lower surface of the upper flange 50 forms an open space portion on one side of the bottom surface of the discharge port 51 penetrating the upper flange 50 to form a passage for the refrigerant flow. At the same time, the upward movement of the opening / closing membrane 62 of the opening / closing portion 61 opened by the compression of the refrigerant is controlled.

상기 구성의 토출밸브구조체에 대한 동작을 설명하면 다음과 같다.Referring to the operation of the discharge valve structure of the above configuration is as follows.

실린더 내부로 유입된 냉매가스가 압축될 경우 실린더 내부에는 높은 압력의 냉매가스가 형성되고, 이 고압력의 냉매가스는 밸브구멍(71) 방향으로 향하게 된다.When the refrigerant gas introduced into the cylinder is compressed, a high pressure refrigerant gas is formed inside the cylinder, and the high pressure refrigerant gas is directed toward the valve hole 71.

이에따라, 상기 냉매가스의 압력이 밸브구멍(71) 상단을 막고 있는 개폐막(62)에 작용하여 상기 개폐막이 개방됨에 따라 냉매가스는 토출구(51)를 통해 토출된다.Accordingly, as the pressure of the refrigerant gas acts on the opening / closing membrane 62 blocking the upper end of the valve hole 71, the refrigerant gas is discharged through the discharge port 51 as the opening / closing membrane is opened.

이때, 개폐부(61)는 상부에 위치한 경사면(52)에 부딪혀 더 이상 밀리지 않으므로 개폐부(61)의 개방량은 적정범위로 제한하게 된다.At this time, the opening and closing portion 61 is hit by the inclined surface 52 located in the upper portion is no longer pushed, the opening amount of the opening and closing portion 61 is limited to an appropriate range.

또한, 상기 개폐막(62)의 넓이는 밸브구멍(71) 단면보다 크게 형성되어야만 일정 고압력의 냉매에 의해 개폐막이 개방되는 것이다.In addition, the opening / closing membrane 62 should be formed larger than the end face of the valve hole 71 so that the opening / closing membrane is opened by the refrigerant having a constant high pressure.

이어서, 개폐부(61)에 가해진 압력이 제거되면 그의 자체탄성에 의해 다시 밸브구멍(71)을 막게된다.Subsequently, when the pressure applied to the opening and closing portion 61 is removed, the valve hole 71 is blocked again by its self-elasticity.

따라서, 본 고안의 토출밸브구조체에서 형성되는 간극 체적은 종래 압축기의 간극 체적(C1)과 비교할 때, 얇은 토출밸브지지판(70)에 형성된 밸브구멍(71)의 부피 정도이므로, 간극 체적이 극소화되며 이로 인해 고온.고압가스의 재팽창 손실을 대폭 줄일 수 있다.Therefore, the gap volume formed in the discharge valve structure of the present invention is about the volume of the valve hole 71 formed in the thin discharge valve support plate 70 as compared with the gap volume C1 of the conventional compressor, so that the gap volume is minimized. This can greatly reduce the re-expansion loss of high temperature and high pressure gas.

이상 설명한 바와 같이, 본 고안 밀폐형 회전압축기의 토출밸브구조체는 토출구를 가진 상부플랜지의 저면에 개폐부를 포함한 토출밸브판 및 밸브구멍을 포함한 토출밸브지지판을 설치 구성하여, 냉매 압축시 간극 체적을 극소화함으로써 압축효율을 향상시킬 수 있는 효과가 있다.As described above, the discharge valve structure of the enclosed rotary compressor of the present invention is provided with the discharge valve plate including the opening and closing portion and the discharge valve support plate including the valve hole on the bottom of the upper flange having the discharge port, thereby minimizing the gap volume during refrigerant compression. There is an effect that can improve the compression efficiency.
