Abstract

본 발명은 하부케이스에 결합된 흡입관으로 고온의 오일이 떨어지지 않도록 함으로서, 흡입관을 타고 흡입되는 냉매의 온도상승에 따라 팽창을 억제하여 압축효율이 감소되지 않도록한 냉장고 압축기의 냉매 흡입장치에 관한 것으로서, 특히 서로 포개져 압력용기를 형성하는 상, 하부케이스와; 상기 하부케이스 내부에 설치되어 모터의 회전에 따라 냉매를 팽창 및 압축하는 실린더블럭과; 상기 하부케이스의 일측에 결합되어 냉매를 상기 실린더블럭 내부로 흡입시키는 흡입관과; 상기 하부케이스에 담겨진 상태에서 상기 모터의 회전시 상부로 펌핑되는 오일과; 그리고 상기 하부케이스 내벽에 설치되어 오일이 상기 흡입관으로 흘러내리지 않도록 차단하는 보호부재가 구비된다.The present invention relates to a refrigerant suction device for a refrigerant compressor in which high temperature oil is not dropped by a suction pipe coupled to a lower case so that compression efficiency is not reduced by suppressing expansion in accordance with a temperature rise of a refrigerant sucked on a suction pipe, An upper case and a lower case which are superimposed on each other to form a pressure vessel; A cylinder block installed in the lower case for expanding and compressing the refrigerant according to rotation of the motor; A suction pipe connected to one side of the lower case and sucking the refrigerant into the cylinder block; An oil pumped to the upper portion when the motor is rotated in a state of being contained in the lower case; And a protection member installed on the inner wall of the lower case to prevent oil from flowing down to the suction pipe.
