Embodiment 1

[0052] Effects of the compressor 1 of the first embodiment

[0053] The compressor 1 of Embodiment 1 includes: a rotor 21; a stator 22 that rotates the rotor 21 around a rotation axis; a compressor unit 5 that compresses refrigerant by the rotation of the rotor 21; and a container 2 that houses the rotor 21. , the stator 22, and the internal space 7 of the compressor part 5. The rotor 21 includes: a rotor core 31 formed with a plurality of through-holes 36-1 to 36-6 through which the refrigerant flows, and the plurality of through-holes 36-1 to 36-6 have curved portions facing the rotation axis. The V-shaped cross-section protruding in the direction; the lower rotor end plate 32 (first end plate), which covers the lower rotor end surface 34 (first end surface) in the rotor core 31, and the lower rotor end surface 34 (first end surface) 1 end surface) of the two ends where the through holes 36-1 to 36-6 are formed, one end closer to the compressor part 5; and the upper rotor e...

Abstract

A rotor that provides a rotating power to a compressor unit for compressing a refrigerant comprises: a rotor core having formed through-holes (36-1 to 36-6) that have cross sections with a plurality of crotches in a direction away from a rotating axis and through which the refrigerant passes; a first end plate covering a first end surface on which one end of both end portions of the through-holes(36-1 to 36-6) in the rotor core that is on the side closer to the compressor unit is formed; and an upper rotor end plate (33) covering a lower rotor end surface (34) on which the other end of the plurality of holes in the rotor core is formed. The first end plate has formed a first opening portion providing communication between the through-holes (36-1 to 36-6) and an inner space. The upper rotor end plate (33) has formed an upper opening portion (43) providing communication between the through-holes (36-1 to 36-6) and the inner space. The upper rotor end plate (33) has formed protruding portions (44-1 to 44-6 and 45-1 to 45-6) covering each of tip-end portions (36-11 to 36-62) at the ends of each of the crotches of the through-holes (36-1 to 36-6).

Description

technical field [0001] The technology of the present invention involves compressors. Background technique [0002] There is known a hermetic compressor in which a compressor unit and a motor unit are accommodated in an airtight container. The motor unit (electric motor unit) includes a stator (stator) and a rotor (rotor). The stator rotates the rotor by generating a rotating magnetic field. The compressor unit compresses the refrigerant through the rotation of the rotor. A plurality of through holes through which the refrigerant compressed by the compressor unit flows are formed in the rotor. The refrigerating machine oil for lubricating the compressor unit is stored in the airtight container, flows through the plurality of through holes together with the refrigerant compressed by the compressor unit, and is discharged to the downstream device together with the refrigerant. In such a compressor, by restricting the flow of the refrigerating machine oil through the plurali...
