Fig. 1 is the structure chart of an embodiment of the gear line of oils part according to the present invention；
Fig. 2 is the structure chart of an embodiment of the oil baffle according to the present invention；
Fig. 3 is the structure chart of another embodiment of the oil baffle according to the present invention；And
Fig. 4 is the structure chart of an embodiment of the rotary compressor according to the present invention.
Detailed description of the invention
Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Fig. 1 is the structure chart of an embodiment of the gear line of oils part according to the present invention, in conjunction with referring to Fig. 1-Fig. 3, as it can be seen, the invention provides a kind of gear line of oils part, including: rotor 10；Oil baffle 20, is connected with rotor 10, and oil baffle 20 includes base plate 201 and encloses the side plate 202 set on the base plate 20, and base plate 201 has multiple through hole 203.The use of the base plate 201 of oil baffle 20, can replace the baffle plate being arranged on rotor upper surface in prior art, simplifies the structure of compressor.Refrigeration oil can effectively be controlled in compressor by oil baffle by this gear line of oils part, it is prevented that refrigeration oil leaks outside, and greatly reduces compressor and tells oil mass, which thereby enhances compressor reliability, thus improving the performance of air conditioner.
In conjunction with referring to Fig. 1-Fig. 3, it is preferable that gear line of oils part also includes balance weight 30, and balance weight 30 is arranged on side plate 202 upper end.So, make gear line of oils part entirety more firm, improve service behaviour.
In conjunction with referring to Fig. 1-Fig. 3, it is preferable that gear line of oils part also includes rotor stop plate 40, and rotor stop plate 40 is arranged on the lower surface of rotor 10.As such, it is possible to it is more firm to make oil baffle directly coordinate with rotor, effectively prevent leaking outside of oil.
In conjunction with referring to Fig. 1-Fig. 3, it is preferable that base plate 201 is circular.So, it is simple to making, good looking appearance, and can adapt with rotor end-face, reach the effect preventing refrigeration oil from leaking preferably.
In conjunction with referring to Fig. 1-Fig. 3, base plate 201 and side plate 202 are vertically arranged.Spill as such, it is possible to be better protected from refrigeration oil.
In conjunction with referring to Fig. 3 and Fig. 4, side plate 202 has multiple gap 204, and the number of multiple gap 204 is 2-64.So in compressor operation, rotor 10 high speed rotating together followed by oil baffle 20, an eddy flow is formed at these multiple gap 204 places, refrigerant gas and the little oil droplet discharged from passage enter this eddy flow, little oil droplet is thrown in inner walls under the influence of centrifugal force, flow back in compressor along housing wall, so compressor discharged by this scheme energy freezing-inhibiting oil, reduce compressor greatly and tell oil mass, multiple gap 204 numbers are between 2-64, it is possible to reach better freezing-inhibiting oil and discharge the effect of compressor.
As shown in Figure 3, it is preferable that, multiple gap 204 are rectangles, so, can prevent refrigeration oil from flowing out compressor preferably, and certainly, multiple gap 204 can also be other suitable shape such as triangle or circle.
Preferably, base plate 201 and rotor 10 are riveted together.So, it is connected firmly, not easily loosens.
Preferably, base plate 201 is one-body molded with side plate 202 or base plate 201 welds together with side plate 202.So, it is connected firmly and closely.
As shown in Figure 4, present invention also offers a kind of rotary compressor, it adopts above-mentioned gear line of oils part.The most of refrigerant gas discharged from compressor pump is discharged by the opening 601 of motor stator 60, refrigerant gas is by after opening 601, the exhaust channel of process is broadly divided into two parts, i.e. the first exhaust channel 602 and the second exhaust channel 603, gas in first exhaust channel 602 is discharged to top lid wall 80 directly up, through colliding with top lid wall 80, makes flow velocity reduce, the little oil droplet being blended in refrigerant gas precipitates out from refrigerant gas, flows back in compressor oil sump along housing wall.Another part gas, via the second exhaust channel 603, the gas gap by stator winding 604, without oil baffle 20, is exhausted directly in exhaustor, makes the oil droplet being blended in refrigerant gas directly discharge from exhaustor.If compressor discharged by too much refrigeration oil 70, will result in compressor oil starvation, affect compressor pump lubrication, increase compressor power consumption, reduce compressor service life.Meanwhile, refrigeration oil 70 is followed in cold-producing medium entrance system, and owing to flow velocity reduces, refrigeration oil 70 can precipitate out and be attached on two walls, affects air conditioner performance.After oil baffle 20 is installed, the refrigerant gas discharged from the second exhaust channel 603 can collide with this oil baffle 20, thus can change flow velocity and the direction of aerofluxus, aerofluxus after change can continue collision with stator winding 604, so through multiple impacts, little oil droplet in refrigerant gas is adsorbed on housing or stator winding 604 wall in collision process, returns in compressor along housing wall.Meanwhile, in collision process, little oil droplet flow velocity reduces, and is not easy to follow aerofluxus and discharges from exhaustor, so adopting this scheme can reduce compressor greatly tell oil mass.
The present invention keeps off line of oils part and has the rotary compressor of this gear line of oils part, being connected to oil baffle on its rotor, refrigeration oil can effectively be controlled in compressor by the special construction of oil baffle, it is prevented that refrigeration oil leaks outside, compressor can be reduced greatly and tell oil mass, which thereby enhance compressor reliability.
These are only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
