Common rotary compressor is seen accompanying drawing 1-accompanying drawing 2, and the exhaust structure of this rotary compressor has housing 1, is installed in the housing and has the compression member 2 of bearing 5, is installed on the bearing 5 and has the baffler 6 of exhaust port; Rotating component in the drive compression member 2 rotates and has the rotor 4 of equilibrium block 7; Be installed on the housing and supporting and have a motor stator 3 of stator line bag 8 with rotor.
When above-mentioned exhaust structure during in exhaust, pressurized gas are discharged from the exhaust port on the bearing 5, through baffler 6 and form high velocity air by the exhaust port on the baffler 6 and discharge.This high velocity air directly impacts the equilibrium block 7 on the rotor 4, thereby produces bigger energy loss and disorderly eddy current, has caused exhaust resistance increase and noise to increase.
In addition, after impacting equilibrium block 7 from the high velocity air of the exhaust port of baffler 6 ejection, to around disperse mobile, this air-flow directly flows away through the lower space of stator line bag 8, fully do not contact with stator line bag 8, be unfavorable for separating of lubricated oil droplet that gas and its are carried secretly, the oil content that causes at last discharging in the gas is higher, compressor to tell oil mass bigger.
The exhaust structure that Chinese patent literature CN1916425A disclosed a kind of main bearing in revolve type compressor on 18th in 08 month in 2005, this exhaust structure prevents exhaust frontal impact balancing rotor piece by by changing exhaust position, to reduce pneumatic noise.Though this exhaust structure can reduce gas shock, can not initiatively change airflow direction, still be unfavorable for compressor is told the control of oil mass.
The model utility content
The purpose of this utility model aim to provide a kind of simple and reasonable, fabricating cost is low, exhaust resistance is little and energy loss is few, the exhaust structure of the rotary compressor of the high working efficiency of compressor, to overcome deficiency of the prior art.
Press the exhaust structure of a kind of rotary compressor of this purpose design, comprise the compressing mechanism and the electric machine assembly that are arranged in the housing, compressing mechanism comprises bearing, the baffler that has exhaust port is arranged on the bearing, electric machine assembly comprises motor stator that has stator line bag and the rotor that has equilibrium block, its structure characteristic is that the end face of rotor is provided with the fan towards baffler, and the exhaust port of baffler is arranged on the position near the wheel hub of bearing.
Described fan is positioned at the zone that the stator line is surrounded as.
The exhaust port of described baffler is formed by the space between the wheel hub of the center hole of baffler and bearing.
Described fan is arranged on rotor, baffler or the bearing by auxiliary supports.
Described fan comprises the import conducting element, and this import conducting element is arranged on the central hole of baffler.
One end and the baffler of described import conducting element join, and the other end of import conducting element is outstanding to be established, and this other end is arranged on towards the direction that deviates from fan.
The end face of the utility model by rotor is provided with the fan towards baffler, can be under the effect of fan, change the flow direction of exhaust, avoided original energy loss that causes from the direct column air-flow high speed impact balancing rotor piece of discharging of baffler and caused bigger operation noise; And under the effect of fan, the pressure of outside near zone of the exhaust port of baffler is reduced, make the easier discharge of air-flow in the baffler to have reduced exhaust resistance and energy loss, improve the working efficiency of compressor, also reduced pneumatic noise simultaneously.
The air-flow after change direction after the fan effect in the utility model, stator line bag with the flow direction motor stator, when this air-flow streams stator line bag, increased the separation effect of the gas lubricated oil droplet entrained with it, take and enter low gas the lubricants capacity of air-conditioning system out of in the compressor, improved the working efficiency of air-conditioning system.
The utlity model has simple and reasonable, fabricating cost is low, exhaust resistance is little and energy loss is few, the characteristics of the high working efficiency of compressor.
