Embodiment
Below with reference to accompanying drawing and combine embodiment, specify the present invention.
Shown in accompanying drawing 3 and 4 according to first embodiment who is used for the oil baffle of rotary compressor of the present invention; The middle part of oil baffle has the spindle hole 11 of the main shaft that is used to pass rotary compressor and is arranged on a plurality of attachment holes 12 around the spindle hole, is distributed with the turbulence blades 13 of inclination on the side of oil baffle.Attachment hole 12 is used for fixed stop oiled-plate method when assembling.This structures shape of oil baffle its rigging position: oil baffle is installed on the bottom of the rotor of rotary compressor through spindle hole 11, and with the coaxial setting of the rotor of rotary compressor.This rigging position can not cause limitation and restriction to assembly technology, diameter of stator bore and the rotor diameter of the rotor of compressor electric motor, and oil gas separation is better.On a side of oil baffle, be distributed with the turbulence blades 13 of inclination, turbulence blades 13 and oil baffle θ in a certain angle, turbulence blades 13 tilts, and bigger to the disturbance of air-flow, oil gas separation is better.The size of the tilt angle theta of turbulence blades 13 is relevant with the sense of rotation of motor and blade height, and when blade height increased, the tilt angle theta of turbulence blades 13 can reduce relatively.In addition, with respect to the blade perpendicular to oil baffle, thereby the turbulence blades 13 that suitably tilts can not make the disturbance of air-flow cause the increase of gas-flow resistance loss too greatly.Further, the quantity of turbulence blades 13 is more than one, is formed by the shearing bending portion on the outer rim of oil baffle.Turbulence blades 13 is formed by the shearing bending portion that on circular flat board, is stamped to form, and the quantity of turbulence blades 13 can evenly be arranged also and can non-homogeneously arrange to be advisable greater than two.Turbulence blades 13 along the radially direct of the side of the oil baffle at its place on oil baffle.The manufacturing of this kind turbulence blades 13 is fairly simple, can reduce cost of goods manufactured.
According to a second embodiment of the present invention, as shown in Figure 5 further, turbulence blades 13 is vortex shape and distributes on the side of oil baffle, and turbulence blades 13 radially is provided with angle along the bearing of trend of its root and oil baffle.The radially α at an angle of turbulence blades 13 and oil baffle, the effect of this kind turbulence blades 13 separation oil and gas is relatively good.
A third embodiment in accordance with the invention, as shown in Figure 6 further, be distributed with locating blade 14 on another side of oil baffle perpendicular to this side.Locating blade 14 and turbulence blades 13 are distributed in the relative both sides of oil baffle respectively.
The fourth embodiment of the present invention as shown in Figure 7, have on the outer rim of oil baffle towards below with the flange 15 of outside diagonally extending.Outward extending flange 15 has increased the active area of oil baffle when Oil-gas Separation, has optimized structure.Optional, have breach on the flange 15.
As attach shown in Fig. 1 and 2 according to a kind of rotary compressor of the present invention; The main shaft 30 that comprises compressor main body 40, stretches out from compressor main body, be installed in rotor 20 and oil baffle 10 on the main shaft 30; Oil baffle 10 is foregoing oil baffle; Spindle hole 11 through oil baffle 10 middle parts is set on the main shaft 30, and between rotor 20 and compressor main body 40.After the refrigerant gas of air-conditioning was discharged, gas carried out Oil-gas Separation through oil baffle 10 earlier, subsequently through the electric machine rotor air gap.Like this, the gas overwhelming majority that compressor is discharged can both be collided on oil baffle 10, has improved the efficient of Oil-gas Separation, thereby improves the heat exchange efficiency of system, and then has improved the efficiency of air-conditioning.
Further, rotor 20 comprises main equilibrium block 21, and main equilibrium block 21 is positioned at the bottom of rotor 20, and oil baffle 10 is installed on the bottom of main equilibrium block 21.Main equilibrium block 21 is fixedly installed in the bottom of rotor 20 through stay bolt and nut, and an edge lap of oil baffle 10 is in the bottom of main equilibrium block 21 and fastening with nut.Rotor 20 also can comprise pad, through the adjustment of pad, with the plane of assurance oil baffle 10 and the perpendicularity of main shaft 30.It is to be noted; When oil baffle 10 among above-mentioned the 3rd embodiment have the oil baffle of locating blade 14 time; The locating blade 14 of this kind oil baffle can substitute nut and the pad between main equilibrium block and oil baffle, guarantees the installation precision of oil baffle 10 through vertical locating blade 14.According to an embodiment of the invention; One side of main equilibrium block 21 has the projection that cross section is a rectangle; Oil baffle 10 overlaps with projection mutually, and locating blade 14 is distributed on oil baffle 10 and the contacted side of projection, and the height of locating blade 14 equals the height of projection.
In addition, rotary compressor also comprises compressor silencer 50, and oil baffle 10 is positioned at the top of compressor silencer 50.The refrigerant gas of air-conditioning is discharged from the exhaust port of last baffler 50; At first collide on oil baffle 10, owing to oil baffle 10 rotates with rotor 20, so air-flow receives action of centrifugal force to be thrown toward the oil baffle outside; Refrigeration oil in the gas is under centrifugal force and collision effect; Separate, be left in the compressor oil sump, gas is then discharged compressor through the rotor air gap through outlet pipe.Gas directly carries out Oil-gas Separation through oil baffle 10, and no longer passes through other air-condition assemblies after discharging from baffler 50, has improved Oil-gas Separation efficient.
Technological scheme involved in the present invention all can be used in combination with the oil baffle that is positioned at the motor upper end of routine.
From above description, can find out that the above embodiments of the present invention have realized following technique effect:
A kind of rotary compressor of the present invention and oil baffle thereof, the middle part of oil baffle have the spindle hole of the main shaft that is used to pass rotary compressor and are arranged on a plurality of attachment holes around the spindle hole, are distributed with the turbulence blades of inclination on the side of oil baffle.Rotary compressor comprises aforementioned oil baffle, is set on the main shaft through the spindle hole in the middle part of the oil baffle, and between rotor and compressor main body.Oil baffle of the present invention is exceeded the restriction of the assembly technology, diameter of stator bore and the rotor diameter that receive electric machine rotor, and its profile is simple, processing and fabricating convenient, assembly process is simple, cost is low, and does not influence assembly quality, can adapt to requirement of mass production.In addition, the oil gas separation of oil baffle of the present invention is remarkable, has improved the heat exchange efficiency of system, and then has improved the efficiency of air-conditioning.
The above is merely 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 changes and variation, and is different like the sense of rotation according to rotor; The deviation direction of the turbulence blades on the oil baffle can be opposite with each embodiment, the flange on the outer rim of oil baffle also can towards above outward inclining extend.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
