(b) Conventional technology In general, rotary compressors have less vibration than reciprocating compressors and require less eccentricity of the crank, so they are suitable for downsizing the airframe, especially in hermetic compressors. It is known that there is. Conventionally, this type of hermetic rotary compressor has a cylindrical hermetic case, an electric motor fixed to the case, and a motor. The cylinder block of the refrigerant compression device is formed into a squid shape when viewed from above to reduce material consumption, and its outer peripheral surface is tightly fixed to a sealed case. In addition, a terminal for power supply to the electric motor is attached to the earthen wall of the sealed case.

(C) Problems to be Solved by the Invention However, according to the above structure, the cylinder block is formed in a squid shape in order to reduce the amount of material used, so only the legs are in close contact with the inner wall of the sealed case. Therefore, there was a problem in that the rigidity of the sealed case at the cut portions other than the legs was weakened, resulting in increased noise. In addition, the terminal for power supply to the electric motor is attached to the earthen wall of the sealed case due to space constraints within the case, which increases the height of the compressor and facilitates miniaturization. I couldn't do that.

The purpose is to provide a machine.

(e) Function The hermetic rotary compressor of the present invention has the above-described configuration, and allows most of the outer circumferential surface of the cylinder block to be brought into close contact with the inner wall of the hermetic case without increasing the material of the cylinder block.
The rigidity of the case can be greatly increased, and the noise of the compressor can be reduced. In addition, by utilizing the above-mentioned space formed inside the sealed case, the power supply terminal can be installed without increasing the height of the sealed case body (due to increasing the distance between the motor and cylinder block, etc.). The terminal can be attached to the side wall of the sealed case, and the height of the compressor can be reduced since the terminal does not protrude upward. In addition, the terminal is placed in the cutout of the cylinder block, and the terminal is located at the bottom of the motor stator. As a synergistic effect of accommodating the compression device within the coil end, it is possible to bring the electric motor and the bottom wall of the sealed case closer together, thereby promoting downsizing of the compressor. Furthermore, the through holes formed in the cylinder block not only contribute to material reduction, but also provide flexibility to the block and suppress vibrations transmitted from the compression device to the sealed case. It also has the effect of reducing the amount of oil discharged by returning the oil in the discharged gas to the bottom of the case.
