Abstract

본 발명은 밀페형 전도 압축기의 밸브구조에 관한 것으로서, 특히 흡입 및 토출 밸브를 구성하기 위해 실린더에 적층되는 플레이트의 갯수를 줄여주어 각 플레이트 간의 간극 체적을 줄여주고, 또한 냉매의 원활한 흡입 및 토출을 위한 별도의 토출구조를 제공하여 제품의 냉동능력을 향상시키도록 한 밀폐형 전동 압축기의 밸브구조에 관한 것이다.The present invention relates to a valve structure of a hermetic conduction compressor, and in particular, to reduce the number of plates stacked on the cylinder to form a suction and discharge valve, to reduce the gap volume between the plates, and also to smoothly suck and discharge the refrigerant. It relates to a valve structure of a hermetic electric compressor to provide a separate discharge structure for improving the freezing capacity of the product.

종래 밸브구조는 다수의 플레이트를 적층시켜 밸브를 구성함으로서, 밸브간의 공간에 남아있는 압축 냉매의 팽창으로 인하여 흡입밸브가 열리는 시기가 늦어져 냉매가스의 흡입량이 줄어들어 냉동 효율이 저하되며, 또한 피스톤의 왕복 운동에 의해 실린더 내부에서 압축된 냉매가 토출될때 제3플레이트(22)에 형성된 토출밸브(22B)의 강성 때문에 토출밸브(22B)가 열리는 시기가 늦어져 실린더 내의 냉매가 과압축되어 냉매의 온도가 상승하고, 이에 따라 실린더 및 흡입 냉매를 과열시켜 흡입가스의 밀도가 작아져 냉매의 흡입량이 줄어들게 되어 제품의 냉동 효율이 저하되는 문제점이 있다.In the conventional valve structure, a plurality of plates are stacked to form a valve, and the intake valve is delayed to open due to expansion of the compressed refrigerant remaining in the space between the valves, thereby reducing the intake amount of the refrigerant gas, thereby reducing the refrigeration efficiency. Due to the rigidity of the discharge valve 22B formed in the third plate 22 when the refrigerant compressed in the cylinder is discharged by the reciprocating motion, the timing of opening the discharge valve 22B is delayed, so that the refrigerant in the cylinder is overcompressed and the temperature of the refrigerant As a result, the cylinder and the suction refrigerant are overheated, so that the density of the suction gas is reduced, so that the suction amount of the refrigerant is reduced, thereby lowering the freezing efficiency of the product.

따라서, 상기 문제점을 해결하기 위한 본 발명은 밸브를 구성하는 플레이트의 갯수를 줄여 간극 체적을 줄여 주고, 토출밸브를 원추형으로 형성하여 토출구의 체적으로 인한 잔여 가스의 양을 최소화함으로서, 토출되지 않고 남은 잔여 가스의 재팽창으로 인한 손실이 줄어들어 냉매의 흡입량이 많아져 냉동 능력이 향상되는 효과가 있는 밀폐형 전동 압축기의 밸브 구조이다.Accordingly, the present invention for solving the above problems by reducing the number of plates constituting the valve to reduce the volume of the gap, by forming a discharge valve in a conical shape to minimize the amount of residual gas due to the volume of the discharge port, remaining without being discharged It is a valve structure of the hermetic electric compressor which has the effect of reducing the loss due to the re-expansion of the residual gas to increase the suction amount of the refrigerant, thereby improving the refrigerating capacity.
