Plate 231 can extend along straight line, curve or broken line, and guide plate 231 is less than or equal to 90 ° with the angle of horizontal plane, thus leading
More preferable guide effect can be played to plate 231, to realize preferably separating of oil effect.
Certainly, the invention is not restricted to this, in other embodiments of the present invention, with reference to Figure 13, when on rotor core 22
When being formed with cavity 223, guide plate 231 can also stretch in cavity 223, and guide plate 231 is directed away from compressing from inside to outside
The direction of mechanism 3 extends.Specifically, the upper end of guide plate 231 is connected with the side wall of the second through hole 232, the lower end of guide plate 231
From up to down tilt to extend towards near the direction of rotor end plates 23 central axis, and the lower end of guide plate 231 and cavity 223
Diapire is spaced apart from each other, such that it is able to play the detached effect of mist of oil.Wherein, guide plate 231 can be along straight line, curve or folding
Line extends, and guide plate 231 is less than or equal to 90 ° with the angle of horizontal plane, and preferably 45 °, thus guide plate 231 can play
Preferably guide effect, to realize preferably separating of oil effect.
Alternatively, the center of rotor end plates 23 is formed with the through hole 233 of insertion.With reference to Fig. 5 and Fig. 7, through hole 233 is along upper
The center of rotor end plates 23, wherein a diameter of D3 of through hole 233 are run through in lower direction, and cavity 223 is located at rotor core 22 top
Center, and a diameter of D1 of the cavity 223 of cylinder, rotor core 22 is also formed with the installing hole running through along the vertical direction
224, installing hole 224 is located at the center of rotor core 22 for installing bent axle, wherein first through hole 222, installing hole 224, the
Two through holes 232, through hole 233 are all connected with cavity 223, and preferably, D1 >=D2, D1 >=D3.
Here, it should be noted that through hole 233 is fabrication hole, complete assembly technology for auxiliary, when by through hole 233
Diameter D3 do as far as possible little after it is ensured that the coolant major part in cavity 223 is all discharged from the second through hole 232, reduce from through hole
The coolant quantities of 233 discharges, and then make more coolant being mixed with refrigerator oil get on stator 21 line bag 211, improve further and
Ensure mist of oil separating effect.
Below with reference to Fig. 1-Figure 14, the compressor 100 according to the multiple embodiment of the present invention is described.
