본 고안은 스크롤 압축기에 관한 것으로, 특히 선회스크롤에 토출공간을 형성하여 압축가스의 토출시 압력실의 압력불균형으로 인한 선회스크룰의 뒤틀림현상을 방지하도록 한 스크롤 압축기에 관한 것이다.The present invention relates to a scroll compressor, and more particularly to a scroll compressor to form a discharge space in the rotating scroll to prevent the distortion of the rotating scroll due to the pressure imbalance of the pressure chamber during the discharge of the compressed gas.

제1도 및 제2도는 종래 스크롤 압축기를 도시한 것으로, 도면에서 3은 스크롤을 표시하고, 1, 2는 선회스크롤과 고정스크롤을 보인 것이며, 4는 압축실, 5는 토출구를 각각 보인 것이다.1 and 2 show a conventional scroll compressor, in which 3 shows scrolls, 1 and 2 show swing scrolls and fixed scrolls, 4 shows compression chambers, and 5 shows discharge ports.

상기 선회스크롤(1)과 고정스크롤(2)은 동일형상의 와권으로 이루어져 있고, 그 형체는 인볼류트 또는 원호를 조합한 것이다.The turning scroll 1 and the fixed scroll 2 are composed of a spiral winding of the same shape, and the shape is a combination of an involute or an arc.

상기 고정스크롤(2)은 공간에 대하여 정지하고 있으며, 선회스크롤(1)은 고정스크롤(2)과 맞물리면서 공간에 대하여 선회운동(orbiting montion)을 행하도록 되어 있다.The fixed scroll 2 is stationary with respect to the space, and the swinging scroll 1 is engaged with the fixed scroll 2 so as to perform an orbiting montion with respect to the space.

또한, 부호 6은 모터를 표시한 것으로, 그 모터(6)의 로터와 일체로 결합된 주측(7)의 중심은 선회스크롤(1)의 중심과 편심된 상태로서 모터(6)의 회전력을 선회스크롤(1)에 전달하게 되고, 선회스크롤(1)은 올담링(8)에 의해 자전이 방지되면서, 고정스크롤(2)과 상대운동을 하게 되며, 선회스크롤(1)의 선회운동에 의해 양쪽 스크롤(1)(2) 사이에 형성된 압축실(4)의 용적이 줄어들어 흡입관(9)으로부터 유입된 냉매가스를 압축하여 토출캐비티(10)를 거쳐 토출관(11)으로 보내게 된다.Reference numeral 6 denotes a motor, and the center of the main side 7 which is integrally coupled to the rotor of the motor 6 is eccentric with the center of the turning scroll 1 to rotate the rotational force of the motor 6. It is transmitted to the scroll (1), the rotating scroll (1) is prevented from rotating by the old dam ring (8), the relative movement with the fixed scroll (2), both sides by the turning movement of the rotating scroll (1) The volume of the compression chamber 4 formed between the scrolls 1 and 2 is reduced so that the refrigerant gas introduced from the suction pipe 9 is compressed and sent to the discharge pipe 11 through the discharge cavity 10.

제1도 및 제2도에서 미설명부호 12는 메인프레임, 13은 서브프레임, 14는 발란스웨이트, 15는 메인베어링을 각각 보인 것이다.In FIG. 1 and FIG. 2, reference numeral 12 denotes a main frame, 13 subframe, 14 a balance weight, and 15 a main bearing.

상기한 바와 같은 스크롤 압축기는 구동시 흡입관(9)을 통해서 들어온 가스가 선회스크롤(1)이 회전함에 따라 중심쪽으로 밀리면서 용적은 작아지고 압력이 높아져 고압상태로 토출관(11)으로 토출된다.As described above, the scroll compressor as described above is pushed toward the center as the rotating scroll 1 rotates while the gas entering through the suction pipe 9 is driven, and the volume of the scroll compressor is discharged to the discharge pipe 11 under high pressure.

그런데, 종래에는 토출구(5)의 위치와 형상에 따라서 서로 대칭이 되는 좌우압축실(4)은 토출시 압력불균형에 의해 압력차가 생겨서, 고정되어 있지 않은 선회스크롤(1)에 영향을 미침으로써 선회스크롤(1)이 경사지게 되어 회전하는 뒤틀림(overturning) 현상이 발생하게 된다.However, in the related art, the left and right compression chambers 4, which are symmetrical with each other according to the position and shape of the discharge port 5, have a pressure difference due to pressure imbalance at the time of discharging, thereby turning by influencing the unstable swing scroll 1. As the scroll 1 is inclined, a turning overturning phenomenon occurs.

즉, 제2도에서 보는 바와 같이, 선회스크롤(1)이 회전함에 따라 흡입된 가스는 그 용적이 점점 작아져 압축기 중심부에서 하나의 압축실이 되어 토출구(5)를 통해 토출관(11)으로 토출될 때, 선회스크롤(1)이 회전하면서 선회스크롤(1)랩이 고정스크롤(2)랩에서 이탈하기 전에 압축공간(4b)이 먼저 토출구(5)와 연통되고, 압축공간(4a)은 선회스크롤(1)랩이 고정스크롤(2)랩에서 이탈하면서 토출구(5)와 연통하게 되어 순간적으로 압축공간(4b)의 압력과 압축공간(4a)의 압력에 차이가 발생하여 이 압력차가 선회스크롤(1)에 영향을 미쳐 선회스크롤(1)이 주축(7)이 되어 회전에 따라서 경사지게 회전하는 것이다.That is, as shown in FIG. 2, as the turning scroll 1 rotates, the sucked gas gradually decreases in volume, becoming one compression chamber at the center of the compressor, and is discharged through the discharge port 5 to the discharge pipe 11. When being discharged, the compression space 4b first communicates with the discharge port 5 before the turning scroll 1 wraps away from the fixed scroll 2 wrap while the turning scroll 1 rotates. The swing scroll (1) wraps away from the fixed scroll (2) wrap and communicates with the discharge port (5). As a result, a difference occurs in the pressure of the compression space (4b) and the pressure of the compression space (4a). It affects the scroll 1, and the turning scroll 1 becomes the main axis 7, and rotates inclinedly as it rotates.

이와 같이 종래 토출구의 위치와 형상으로 인해 토출시 좌, 우 압축실의 압력에 차이가 발생하게 되어 스크롤 압축기에서 진동과 소음이 발생하며, 정도가 심하면 양쪽스크롤의 저면부와 랩의 측면이 파손되는 문제점이 있었다.Thus, due to the position and shape of the conventional discharge port, there is a difference in the pressure of the left and right compression chamber during discharging, which causes vibration and noise in the scroll compressor. There was a problem.

본 고안의 목적은 토출구의 대응부에 토출홈을 형성하여 토출시 좌우 압축실의 압력차를 없애 압축가스가 균일하게 토출구를 통해 토출되어 뒤틀림 현상이 방지됨으로써 진동과 소음을 없애도록 하고 스크롤의 파손을 막으려는데 있다.The purpose of the present invention is to form a discharge groove in the corresponding portion of the discharge port to eliminate the pressure difference between the left and right compression chambers during the discharge, so that the compressed gas is uniformly discharged through the discharge port to prevent distortion and to eliminate vibration and noise, and to break the scroll To stop.

이와 같은 본 고안의 목적을 달성하기 위하여, 고정스크롤과 선회스크롤이 맞물려 작동하는 스크롤 압축기에 있어서, 상기 고정스크롤에서는 선회스크롤의 외측부와 고정스크롤의 내측부가 접하는 영역에 토출구를 형성하고, 상기 선회스크롤에는 선회스크롤의 내측부와 고정스크롤의 외측부가 접하는 영역임과 동시에 상기 토출구와 180°위상차를 갖는 영역에 토출홈을 형성하여서 된 것을 특징으로 하는 스크롤 압축기가 제공된다.In order to achieve the object of the present invention, in the scroll compressor in which the fixed scroll and the rotating scroll is engaged, in the fixed scroll, the discharge port is formed in an area where the outer side of the rotating scroll and the inner side of the fixed scroll contact, The scroll compressor is provided by forming a discharge groove in an area where the inner side of the swinging scroll and the outer side of the fixed scroll are in contact with each other and having a 180 ° phase difference with the discharge port.

이하, 상기 본 고안을 첨부도면에 도시한 실시예에 따라서 상세히 설명한다.Hereinafter, the present invention will be described in detail according to the embodiment shown in the accompanying drawings.

제3도는 본 고안 스크롤 압축기의 스크롤의 작용도이고, 제4도는 본 고안 스크롤 압축기의 스크롤의 작용을 보인 확대도이며, 제5도는 본 고안 스크롤 압축기의 스크롤 중심부의 단면도를 도시한 것으로, 먼저 제3도에서와 같이 선회스크롤(1)의 회전하여 이탈지점(16a)(16b)에 도달하였을 때 고정스크롤(2)의 내측부와 선회스크롤(1)의 외측부가 접하는 영역에 토출구(5')를 형성하고, 선회스크롤(1)의 내측부와 고정스크롤(2)의 외측부가 접하는 영역임과 동시에 상기 토출구(5')와 180°위상차를 가지는 영역에 토출홈(18)을 형성한다.3 is an operation diagram of the scroll compressor of the present invention, Figure 4 is an enlarged view showing the action of the scroll compressor of the present invention, Figure 5 is a cross-sectional view of the scroll center of the present invention scroll compressor, first As shown in FIG. 3, when the turning scroll 1 is rotated to reach the departure points 16a and 16b, the discharge port 5 'is opened in the area where the inner side of the fixed scroll 2 and the outer side of the turning scroll 1 contact each other. And a discharge groove 18 is formed in a region where the inner portion of the turning scroll 1 and the outer portion of the fixed scroll 2 are in contact with each other and at a 180 ° phase difference with the discharge port 5 '.

상기 토출구(5')는 관통하여 형성하고, 상기 토출홈(18)은 일정깊이만큼 토출공간으로서의 홈으로 형성하는 것이 바람직하다.The discharge port 5 'is formed through, and the discharge groove 18 is preferably formed as a groove as a discharge space by a predetermined depth.

또한, 상기 토출구(5')와 토출홈(18)은 원형상으로 형성하고 동일한 크기로 형성하여야 한다.In addition, the discharge port 5 'and the discharge groove 18 should be formed in a circular shape and the same size.

이와 같이 구성되는 본 고안에 의한 스크롤 압축기는 압축기가 구동되어 흡입관(9)을 통해 유입되는 압축가스가 선회스크롤(1)의 회전으로 인해 중심부로 이동하게 되면서 용적이 작아지고 압력이 높아진 상태에서 이탈지점(16a)(16b)을 지나 토출되게 되는데, 이때 압축공간(17a)(17b)의 압축 가스는 토출구(5')와 토출홈(18)을 통해 각각 연통됨으로써 회전각에 해당하는 토출유로면적(19a)(19b)을 통해 토출구(5')로 토출되게 된다.The scroll compressor according to the present invention configured as described above moves away from the compressed gas flowing through the suction pipe (9) to the center due to the rotation of the turning scroll (1) while the volume is smaller and the pressure is increased. The discharge gas passes through the points 16a and 16b, and the compressed gas in the compression spaces 17a and 17b communicates with each other through the discharge port 5 'and the discharge groove 18, respectively, and the discharge flow path area corresponding to the rotation angle. It is discharged to the discharge port 5 'through 19a and 19b.

이와 같이 선회스크롤(1)이 고정스크롤(2)에서 이탈할 때에 압축공간(17a)(17b)이 동시에 토출구(5')와 토출홈(18)으로 연통되어 압축가스가 균일한 압력을 갖고 토출하게 됨으로써 압력불균형을 방지하게 되는 것이다.In this way, when the turning scroll 1 is separated from the fixed scroll 2, the compressed spaces 17a and 17b communicate with the discharge port 5 'and the discharge groove 18 at the same time, so that the compressed gas is discharged with a uniform pressure. This will prevent pressure imbalance.

이상에서 설명한 바와 같이 본 고안에 의하여 토출구와 토출홈을 형성함으로써 압축가스의 토출시 좌우압축실의 압력차가 발생하지 않아 압축가스가 균등하게 토출구가 토출하게 되어 압력불균형으로 인한 선회스크롤의 뒤틀림현상을 방지하게 됨으로써, 이상진동과 이상음을 없애고 스크롤의 파손을 예방하게 되는 효과가 있다.As described above, by forming the discharge port and the discharge groove, the pressure difference between the left and right compression chambers does not occur when the compressed gas is discharged, so that the discharge port is discharged evenly by the compressed gas. By preventing it, there is an effect of eliminating abnormal vibration and abnormal sounds and preventing breakage of the scroll.
