Background technique
The air exit of the current compressor compresses pump housing is generally on the inside of upper bearing (metal) end face, muffler exhaust outlet There are the rotor and main balance weight of high-speed rotation, rotor and main balance weight of the in line upward exhaust airstream by high-speed rotation above Beating, agitation, flow rotation makes the refrigeration oil of compressor lower end oil sump volatilize, flow and violent makes exhaust airstream oil content height.
Therefore, how to avoid balance weight from hitting the power consumption of high-speed flow loss, how to reduce compressor oil drainage amount, how to keep away It is high to exempt from exhaust oil content caused by flow rotation agitation, how to reduce motor power consumption, improves compressor performance, it has also become this field Technical staff's urgent problem to be solved.
Summary of the invention
In view of this, being hit the purpose of the present invention is to provide a kind of exhaust structure of compressor to avoid balance weight high The power consumption of fast windage loss improves compressor performance.
To achieve the above object, the invention provides the following technical scheme:
A kind of exhaust structure of compressor, comprising: first bearing and muffler, the upper bearing (metal) are included in center one Upper axis, the muffler of body formation include the axis hole in center, and the axis hole passes through the upper axis for the muffler The top of the first bearing is set, the muffler further includes screw hole, by the screw hole by the muffler with The first bearing is fixed, and is formed sealing space between the muffler and the first bearing, is arranged in the first bearing There are multiple gas vents;
Preferably, the fixed fairlead in the gas vent upper end being arranged on the first bearing edge;
Preferably, the fairlead is 4;
Preferably, the fixed form of the fairlead is welding;
Preferably, wherein described may extend to stator punching without the port part of the fairlead of stator trimming, and in electricity Except machine winding coil;The port part of the fairlead by stator trimming may extend in the middle part of stator;
Preferably, the fairlead without stator trimming is 2;The fairlead by stator trimming is 2;
Preferably, the bottom of the fairlead includes multiple gas vents;
Preferably, the gas vent of the bottom in fairlead is 2;
The present invention also provides a kind of compressor, including exhaust structure, the exhaust structure is row described in any of the above embodiments Depressed structure.
It can be seen from the above technical scheme that the exhaust structure of compressor provided by the invention, by upper flange Multiple radial holes are outputed in big flat wall thickness, aperture is connected in vertical direction with seal chamber, and the area of aperture is more than or equal to original Fairlead was fixed on by the multiple apertures in upper flange edge, without drawing for stator trimming by the area of muffler exhaust outlet Outlet pipe is on the outside of stator winding and stator punching trimming is vented upwards, and the fairlead by stator trimming is cut at stator punching two It can be increased as far as possible on side, make exhaust farther away from lower end oil sump, while also made to be vented rotor and master far from high-speed rotation and putting down Weigh block, avoids exhaust oil content caused by flow rotation agitation high.
The present invention also provides a kind of compressors with exhaust structure.Since the exhaust structure of above-mentioned compressor is with upper Technical effect is stated, the compressor with the exhaust structure should also have same technical effect.It no longer introduces one by one herein.
Detailed description of the invention
