を持たせることが可能となる。Function In the hermetic electric compressor of the present invention, the refrigerant gas discharged to the discharge chamber is discharged to the two discharge mufflers through the communication holes, so that the actual volume in the discharge muffler becomes large and the pressure pulsation due to overcompression occurs. The component can be attenuated and the input can be reduced. In addition, of the two discharge mufflers, the discharge muffler that is not in communication with the discharge pipe is divided into a chamber that communicates with the communication hole and a chamber that does not communicate with the communication muffler by a partition plate with holes. Since the structure is adopted, the resonance frequency can be changed depending on the size of the hole of the partition plate and the shape of the hole portion, and the noise damping effect can be given to a plurality of frequency ranges.

の低減を図ることができる。In the above structure, one of the refrigerant gases discharged into the discharge chamber 55a is discharged into the discharge muffler first chamber 2a through the communication hole 1 and further into the discharge muffler second chamber 2b through the hole 3a of the partition plate 3. It The other refrigerant gas is discharged into the discharge muffler 57 through the communication hole 56, and is further guided to the discharge pipe 58 through the discharge line 59. Therefore, the refrigerant gas discharged to the discharge chamber 55a passes through the communication hole 1 and the communication hole 56, and the discharge muffler.
2. Since the liquid is discharged to the discharge muffler 57, the actual volume inside the discharge muffler 57 becomes large and the input due to overcompression can be reduced. Further, since the discharge muffler has a bilaterally symmetrical structure, there is an advantage that the dead space can be effectively used. Further, the discharge muffler 2 has a resonance muffler structure, and the resonance frequency can be changed depending on the size of the hole of the partition plate and the shape of the hole portion, and the effect of reducing the noise level can be given to an arbitrary frequency range. At the same time, the pressure pulsation can be reduced by the two-stage expansion action of the resonance muffler structure.

Furthermore, of the two discharge mufflers, the discharge muffler that is not in communication with the discharge pipe is separated by a partition plate with holes.
Since the communication hole is divided into a chamber that communicates with a chamber that does not communicate with the communication hole, the actual volume of the discharge muffler can be expanded to reduce input by preventing overcompression. It is possible to reduce the noise level by changing the frequency and reduce the pressure pulsation due to the two-stage expansion action.
