摘要： The present invention relates to a discharging noise system of a hermetic compressor. The present invention includes a first discharging noise suppressor (39) provided at one side end of a cylinder block 35 to firstly reduce noise and pulsation of work fluid compressed in and discharged from a compressing chamber (37) formed to be bored through the cylinder block (35) in a fore and aft direction, a second discharging noise suppressor (39') provided at the other side end of the cylinder block (35) and communicating with the first discharging noise suppressor 39 to secondarily reduce noise and pulsation of the work fluid with noise and pulsation reduced by the first discharging noise suppressor (39), a connection pipe (43) for allowing the first and second discharging noise suppressors (39) and (39') to communicate with each other to form a channel for allowing the work fluid to move, the connection pipe (43) having a length longer than a shortest straight distance between the discharging noise suppressors (39 and 39'), and a discharging pipe (45) provided at the second discharging noise suppressor (39') to form a channel through which the work fluid is discharged to the outside. According to the present invention configured as above, the connection pipe is relatively long to reduce pulsation, thereby improving operating characteristics of the hermetic compressor, so that vibration generated by the pulsation is reduced to improve durability of the hermetic compressor.

摘要： The present invention discloses a compressor including a hermetic container into/from which refrigerant is sucked and discharged, a compression unit provided in the hermetic container and compressing the refrigerant, a motor unit provided in the hermetic container to be connected to the compression unit and driving the compression unit, and one or more irregular reflection portions provided on an outer circumferential surface of the motor unit. The irregular reflection portion repeatedly reflects and dissipates noise and vibration in the compressor to improve the noise reduction effect. In addition, the irregular reflection portion increases the surface area of the motor unit to improve the radiation effect, which results in high efficiency of the entire compressor.
