It is coupled to the upper bearing plate (3A) and the lower bearing plate (3B) and the rotor (Mr) of the power mechanism part to pass through the respective bearing plates (3A, 3B) to transmit the power of the power mechanism part to the compressor sphere. The upper and lower sides of the rotary shaft 4 and the rotary shaft 4 to be coupled to or integrally molded to partition the internal space V of the cylinder 2 into the first space S1 and the second space S2. The partition plate 5 formed in a sinusoidal shape so as to have a bend point at each of the spaces, and the respective spaces S1 and S2 during the rotation of the rotary shaft 4 by contacting the lower and upper ends respectively on both sides of the partition plate 5. First vane 6A and second vane 6B, which partitions the The first spring assembly 7A and the second spring assembly 7B, which elastically support the vanes 6A and 6B, are installed on the outer surfaces of the upper bearing plate 3A and the lower bearing plate 3B, respectively. An upper muffler 8A and a lower muffler 8B are included to attenuate the discharge noise of the compressed gas discharged from the spaces S1 and S2.

실린더(2)는 그 중앙부에 구획판(5)에 의해 제1 공간(S1)과 제2 공간(S2)으로 나뉘는 내부공간(V)을 원형으로 형성하고, 일 측에는 실린더(2)의 외주면에서 내부공간(V)의 내주면까지 길게 관통하여 흡입가스를 상기한 내부공간(V)으로 유도하는 흡입구(2a)를 형성하고 있다.The cylinder 2 has a circular shape in the center of the inner space (V) divided into the first space (S1) and the second space (S2) by a partition plate 5, on one side at the outer peripheral surface of the cylinder (2) A suction port 2a is formed to penetrate to the inner circumferential surface of the inner space V to guide the suction gas to the inner space V.

이에 도시한 바와 같이 본 발명에 의한 밀폐형 압축기의 압축기구부는 도 1에서와 같이 유체를 흡입 압축하도록 밀폐된 내부공간(V)을 가지는 실린더조립체와, 실린더조립체의 내부공간(V)에 삽입 결합하여 그 실린더조립체의 내부공간(V)을 복수 개의 밀폐공간(S1)(S2)으로 구획하고 전동기구부의 회전력을 전달하는 회전축(4)에 일체 또는 후조립으로 결합하여 회전축(4)과 함께 회전하면서 냉매가스를 이동시키는 구획판(5)과, 구획판(5)의 상하 양측면에 압접하도록 실린더조립체에 삽입 결합하여 냉매가스의 이동을 차단함으로써 압축시키는 복수 개의 베인(6A)(6B)을 포함한다.As shown in FIG. 1, the compression mechanism of the hermetic compressor according to the present invention is inserted into and coupled to the cylinder assembly having the sealed inner space V and the inner space V of the cylinder assembly, as shown in FIG. 1. The inner space (V) of the cylinder assembly is partitioned into a plurality of sealed spaces (S1) (S2) and rotated together with the rotary shaft (4) by integrally or post-assembled to the rotary shaft (4) for transmitting the rotational force of the electric machine part. A partition plate 5 for moving the refrigerant gas, and a plurality of vanes 6A and 6B inserted into and coupled to the cylinder assembly to press-contact the upper and lower sides of the partition plate 5 to block the movement of the refrigerant gas. .

실린더조립체는 그 중앙에 내부공간(V)을 형성하고 상기한 밀폐공간(S1)(S2)에 함께 연통하도록 흡입구(11)를 가지는 실린더(10)와, 실린더(10)의 상하 양측 면에 결합하여 함께 내부공간(V)을 형성하고 각 밀폐공간(S1)(S2)에 연통하도록 토출구(미도시)를 구비함과 아울러 회전축(4)을 지지하는 상부베어링플레이트(3A) 및 하부베어링플레이트(3B)로 이루어진다.The cylinder assembly forms an inner space (V) at its center and is coupled to the cylinder (10) having a suction port (11) so as to communicate with the closed space (S1) (S2) together with the upper and lower sides of the cylinder (10). The upper bearing plate 3A and the lower bearing plate supporting the rotating shaft 4 and having a discharge port (not shown) so as to form an inner space V and communicate with each of the sealed spaces S1 and S2. 3B).

실린더는 도 5 및 도 6에서와 같이 환형으로 형성하고 그 일 측에 상기한 흡입구(11)를 외주면에서 내주면으로 관통하도록 형성하되, 흡입구(11)는 그 출구단인 실린더(10)의 내주면에 출구측 면적을 확장하기 위한 가스안내홈(12)을 형성한다.The cylinder is formed in an annular shape as shown in Figs. 5 and 6 and formed so that the suction port 11 penetrates from the outer circumferential surface to the inner circumferential surface on one side thereof, and the suction port 11 is formed on the inner circumferential surface of the cylinder 10, the outlet end thereof. A gas guide groove 12 is formed to expand the outlet side area.

가스안내홈(12)은 흡입구(11)의 직경과 동일한 폭을 가지고 축방향으로 수직하게 형성하는데, 이 경우 가스안내홈(12)의 폭과 깊이는 실린더(10)의 내경, 즉 각 밀폐공간(S1)(S2)의 체적에 비례하여 적절하게 조절하는 것이 바람직하다.The gas guide groove 12 has the same width as the diameter of the inlet 11 and is formed vertically in the axial direction. In this case, the width and depth of the gas guide groove 12 are the inner diameter of the cylinder 10, that is, each sealed space. It is preferable to adjust suitably in proportion to the volume of (S1) (S2).

도면중 종래와 동일한 부분에 대하여는 동일한 부호를 부여하였다.In the drawings, the same reference numerals are given to the same parts as in the prior art.

상기와 같은 본 발명 밀폐형 압축기의 흡입손실 저감구조는 다음과 같은 작용 효과가 있다.The suction loss reduction structure of the hermetic compressor of the present invention as described above has the following effects.

즉, 전동기구부에 전원을 인가하여 구획판(5)이 어느 한 방향으로 회전하면, 이와 함께 구획판(5)의 상하 양 측면에 각각 접촉한 제1베인(도 1에 도시)(6A)과 제2베인(도 1에 도시)(6B)이 구획판(5)을 따라 서로 반대쪽 축방향으로 상하 왕복하면서 실린더(10)의 제1 공간(S1)과 제2 공간(S2)으로 새로운 냉매가스를 연속으로 흡입 압축하였다가 각각의 토출구(미도시)를 통해 번갈아 토출하는 일련의 과정을 반복한다.In other words, when the partition plate 5 is rotated in either direction by applying power to the electric mechanism, the first vanes (shown in FIG. 1) 6A which are in contact with the upper and lower sides of the partition plate 5, respectively, and The second vane (shown in FIG. 1) 6B moves up and down in the axial direction opposite to each other along the partition plate 5 to form a new refrigerant gas into the first space S1 and the second space S2 of the cylinder 10. Is continuously compressed by suction and then alternately discharged through each discharge port (not shown).

여기서, 냉매가스는 각 밀폐공간(S1)(S2)의 체적변화에 따라 흡입구(10)를 통해 상기한 밀폐공간(S1)(S2)으로 연속하여 흡입되는데, 구획판(5)이 회전하는 중에 어느 시점에서는 흡입구(10)의 양쪽 끝단에 겹치도록 위치하여 일정 정도의 회전각도 동안 냉매가스의 흡입을 차단함에 따라 냉매가스의 흡입손실을 유발할 우려가 있으나, 도 7에서와 같이 냉매가스는 상기 구획판(5)에 의해 흡입구(11)의 정면쪽이 막히더라도 그 흡입구(11)의 출구측에 연결된 가스안내홈(12)을 따라 상하 양쪽이나 좌우 양쪽 또는 주변으로 빠져나가 구획판(5)의 상하 양쪽에 구비한 각각의 밀폐공간(S1)(S2)으로 흡입된다. 이에 따라 냉매가스는 구획판(5)의 회전각도에 관계없이 지속적으로 흡입되어 그만큼 냉매가스의 흡입손실을 줄일 수 있다.Here, the refrigerant gas is continuously sucked into the sealed space (S1) (S2) through the suction port 10 in accordance with the volume change of each sealed space (S1) (S2), while the partition plate (5) is rotating At some point, the suction port 10 may be overlapped with both ends of the suction port 10 to block the suction of the refrigerant gas for a predetermined rotation angle, thereby causing the suction loss of the refrigerant gas. However, as shown in FIG. Even if the front side of the inlet port 11 is blocked by the plate 5, the gas outlet groove 12 connected to the outlet side of the inlet port 11 exits up and down, left and right sides, or the periphery of the partition plate 5. It is sucked into the respective sealed spaces S1 and S2 provided on both the upper and lower sides. Accordingly, the refrigerant gas is continuously sucked regardless of the rotation angle of the partition plate 5, thereby reducing the suction loss of the refrigerant gas.

한편, 가스안내홈(12)을 도 8과 도 9에서와 같이 원주방향으로 길게 형성하거나 흡입구(11)의 직경 보다 크게 형성하더라도 그만큼 구획판(5)에 의해 밀폐공간이 닫히는 시간을 줄일 수 있어 냉매가스의 흡입손실을 줄일 수 있다.On the other hand, even if the gas guide groove 12 is formed long in the circumferential direction as shown in Figs. 8 and 9 or larger than the diameter of the suction port 11, the time for closing the closed space by the partition plate 5 can be reduced accordingly. The suction loss of the refrigerant gas can be reduced.

이렇게 하여 냉매가스가 각각의 흡입공간으로 연속하여 흡입됨에 따라 냉매가스가 원활하게 흡입되면서 흡입손실을 줄이고 이를 통해 압축기 효율을 높일 수 있다.In this way, as the refrigerant gas is continuously sucked into each suction space, the refrigerant gas is smoothly sucked, thereby reducing the suction loss and thereby increasing the compressor efficiency.

본 발명에 의한 밀폐형 압축기의 흡입손실 저감구조는, 실린더의 내주면에 흡입구와 연결되는 가스안내홈을 음각지게 형성함으로써, 구획판에 의해 흡입구의 일부가 막히더라도 냉매가스는 상기한 가스안내홈을 따라 각각의 밀폐공간으로 원활하게 유입되도록 하여 압축기의 흡입손실을 막고 이를 통해 압축기 효율을 높일 수 있다.In the suction loss reduction structure of the hermetic compressor according to the present invention, the gas guide groove connected to the suction port is engraved on the inner circumferential surface of the cylinder so that even if a part of the suction port is blocked by the partition plate, the refrigerant gas follows the gas guide groove. It is possible to smoothly flow into each sealed space to prevent the suction loss of the compressor and thereby increase the compressor efficiency.
