Embodiment
Now, describe according to a preferred embodiment of the present invention with reference to the accompanying drawings.
With reference to Fig. 3, the closed compressor of application oil rig according to a preferred embodiment of the present invention comprises: housing 40 is positioned at the electrically driven 50 of housing 40, compression set 60, and oil rig 70.
Electrically driven 50 comprises: bent axle 51; Rotor 53, it links to each other with bent axle 51 and rotates with bent axle 51; Stator 55, it is positioned at the outside of rotor 53.Bent axle 51 is supported on the bearing 57 rotationally.In addition, eccentric part 59 is installed in the upper end of bent axle 51.
In sum, when eccentric part 59 is positioned in the upper end of bent axle 51, and cylinder block 61 is when being positioned in the top of compressor, and it is known as cylinder top loaded type compressor (dog link).
On the other hand, Fig. 5 A and 5B show oil rig according to a further advantageous embodiment of the invention.The impeller portion that is formed on the oil pick-up tube 171 comprises some cambered aerofoils 173, and it cuts into predetermined shape by the bottom with oil pick-up tube 171 and forms so that stretch out towards inner circumferential side cutting part is crooked.Therefore, cambered aerofoil 173 have along oil pick-up tube 171 to the predetermined tilt angle of angular direction and predetermined length.When oil pick-up tube 171 rotation with above-mentioned structure, the oil 41 endoporus 171a by oil pick-up tube 171 are extracted, and hole 171b is when shaping cambered aerofoil 173 and on the circumference that is shaped outside.Oil 41 centrifugal force by cambered aerofoil 173 are directed to top and are supplied.
In addition, Fig. 6 A and 6B show oil pick-up tube 271 according to a further advantageous embodiment of the invention.The impeller portion that is formed on the oil pick-up tube 271 comprises plurality of projections 273, and it is along the circumferencial direction of oil pick-up tube 271 lower ends and be formed with intended distance.Cutting part 272 cuts certain degree of depth from the lower end of oil pick-up tube 271, and between protuberance 273.In other words, protuberance 273 is formed by processing cutting part 272.And protuberance 273 has from the inclined side 273a of an end to the inner circumference inclination, and therefore oil 41 can effectively be extracted.
Simultaneously, Fig. 7 shows the closed compressor of application oil rig according to a further advantageous embodiment of the invention.Shown closed compressor is a cylinder underneath type compressor (non-dog link), and it has an eccentric part 359 that is positioned at bent axle 351 lower ends, and a cylinder block 361 that is positioned at the compressor bottom.Cylinder underneath type compressor comprises: housing 340, be equipped with oil 341 in the bottom of housing 340; Electrically driven 350, it has rotor 353 and stator 355 and with bent axle 351 rotations; Compression set 360, it is positioned at the bottom of bent axle 351; And oil rig 370.Here, electrically driven 350 and compression set 360 have and electrically driven shown in Figure 3 50 and compression set 60 identical construction, therefore, have omitted about their explanation.But, be positioned in the lower end of bent axle 351 according to the compression set 360 of the preferred embodiment.
Simultaneously, an eccentric part 359 that links to each other with connecting rod 365 is set at the lower end of bent axle 351.
In the above construction, the following pipe 371c of portion is immersed in the oil 341, and rake 371b is positioned at the outside of oil 341.Therefore, when bent axle 351 rotation, the last pipe 371a of portion rotate prejudicially with eccentric part 359, still time 371c of pipe portion in its position with bent axle 351 coaxial rotations.At this moment, be positioned at the effect that impeller plays in the following unit operation portion 373 of the lower end of the 371c of pipe portion.In other words, oil 341 is drawn in the endoporus of oil pick-up tube 371 by unit operation portion 373, and by the 371c of pipe portion down.Then, the oil 341 that arrives rake 371b is accelerated owing to centrifugal force makes feed speed.So far, when compressor during by initial driving, the impeller of unit operation portion 373 is drawn into oil the rake 371b from the 371c of pipe portion down.Then, after driving, the centrifugal force of rake 371b plays important effect in the supply of oil 341, and therefore, oil can effectively be extracted.
On the other hand, shown in Fig. 9 A and 9B, have cambered aerofoil 373 ' and protuberance 373 " oil pick-up tube 371 ' and 371 " can be used for replacing and oil pick-up tube 371.
According to the oil rig of the closed compressor of having described, because impeller is formed on the oil pick-up tube, so the structure of compressor becomes simpler.Therefore, prime cost has reduced, the manufacturing of compressor simultaneously and use convenient.
In addition, can easily be applied to cylinder top loaded type compressor and cylinder underneath type compressor according to oil rig of the present invention.
Though described according to a preferred embodiment of the invention, those of ordinary skill in the art is to be understood that: the present invention is not restricted to described preferred embodiment.In by the determined the spirit and scope of the present invention of appended claims book, can make various changes and modification.
