Abstract
The invention discloses an air-out structure of compressor, which consists of upper bearing and silencer, wherein the upper bearing contains upper axle formed in the central position; the silencer displays convex cover shape with axle hole in the central position, which covers on the top of bearing throughout the axle hole and fixes upper bearing by screw pin hole; the silencer is a uniform sealed face except axle hole and screw pin hole; the air-out groove is set on the upper bearing and formed on one side of inner upper bearing. The structure adds the flowing time of compressive gas out of air-vent due to enlarging the space after certain circulation when the gas enters the silencer. The invention reduces the gas power and noise due to adding gas transmitting loss, when the gas is drained out of air-vent on the upper bearing without air vent on the silencer.
Description
Technical field
The present invention relates to a kind of compressor.Particularly relate to a kind of by increasing the flowing time of pressurized gas discharge relief opening, the exhaust structure of the compressor of reduction noise.
Background technique
Rotary compressor is widely used in various refrigerators, the air-conditioning, rotary compressor sucks the gaseous coolant through evaporator evaporation, after it is compressed to rated pressure, be discharged into the work system of refrigerant again, rotary compressor is the compressor that can suck and discharge refrigerant continuously.
Traditional rotary compressor is to be provided with suction port and output tube, and the inside that is filled with the shell of certain gauging is equipped with the stator and the rotor of motor; And be pressed into running shaft in its centre of rotor; Below running shaft, be provided with the press part that absorbs compression refrigerant.
The press part of its compressor, after compressor was connected power supply, the running shaft that the rotor banding dynamic pressure of motor part is gone in the rotor together rotated.Along with the rotation of running shaft, the eccentric part that the running shaft lower end forms and roll the ring rotation with eccentric part combines will enter the refrigerant gas that the interior low-temperature low-pressure refrigerant gas compression of compression volume becomes High Temperature High Pressure through the suction port of cylinder.Export by valve member through as above process compressed refrigerant, by cylinder, through upper bearing (metal), after reducing a part of noise by silencing apparatus again, export the inside of seal container to by the through hole of baffler, arriving vent ports, discharge outside the compressor more afterwards through the slit between rotor and the stator.
Therefore, the rotary compressor press part is the cardiac component that produces compression process, also is the main source that noise and vibration produce.
Fig. 1 is that the silencing apparatus of prior art combines schematic representation with upper bearing (metal); Fig. 2 is the structural representation of the silencing apparatus of prior art; Fig. 3 is the structural representation of the upper bearing (metal) of prior art.
As Fig. 1, Fig. 2, shown in Figure 3, when existing compressor operating, the pressurized gas of generation enters by upper bearing (metal) 4 in the chamber of baffler 1, and the exhaust port from the baffler 12 is discharged again.Because the gas that enters in the baffler 1 is pressurized gas, when its after directly the exhaust port 2 from the baffler 1 is discharged, produce friction with the motor rotating at high speed rotor, thereby produce noise.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of by increasing the flowing time of pressurized gas at relief opening, the exhaust structure of the compressor of reduction noise.
The technical solution adopted in the present invention is: a kind of exhaust structure of compressor, including upper bearing (metal) and baffler constitutes, described upper bearing (metal) includes the integrally formed upward axle in heart position therein, baffler is the lid shape of convex, its central position is formed with axis hole, baffler passes the top that axle is placed on upper bearing (metal) of going up of upper bearing (metal) by the axis hole on it, and fix by screw hole and upper bearing (metal), part on the baffler except that axis hole and screw hole is sealing surface, the annular element that covers the cylinder opening part that constitutes upper bearing (metal) is provided with air vent, the described end of the air vent on the upper bearing (metal) that is formed on is connected with exhaust passage in being formed on upper bearing (metal), and the other end is connected with the inside of baffler.
The present invention is owing to adopt said structure, increase pressurized gas and just discharged the flowing time of relief opening, when entering silencing apparatus, because the expansion in space, after certain circulating, gas is discharged by the air vent in the upper bearing (metal), and then it is upwards mobile through the gap on upper bearing (metal) both sides, increase the transmission loss of gas like this, the energy of gas is reduced, reduced noise.
In addition, the present invention does not have relief opening on silencing apparatus, and gas can not directly be discharged from the silencing apparatus, has avoided because the aperture on the silencing apparatus is discharged gas, makes gas between gas and motor rotating at high speed rotor and solid high-speed motion and the sound that rubs out.Thereby better reduce noise.

Embodiment
Below in conjunction with drawings and Examples, the present invention is done detailed explanation.
Fig. 4 is the structural representation of silencing apparatus of the present invention; Fig. 5 is the structural representation of upper bearing (metal) of the present invention; Fig. 6 is that silencing apparatus of the present invention combines schematic representation with upper bearing (metal).
As shown in the figure, the exhaust structure of compressor, including upper bearing (metal) 4a and baffler 1a constitutes, described upper bearing (metal) 4a includes the integrally formed upward axle 6 in heart position therein, baffler 1a is the lid shape of convex, its central position is formed with axis hole 7, baffler 1a passes the top that axle 6 is placed on upper bearing (metal) 4a of going up of upper bearing (metal) 4a by the axis hole on it 7, and fix with upper bearing (metal) 4a by screw hole 3, the part that baffler 1a goes up except that axis hole 7 and screw hole 3 is sealing surface, upper bearing (metal) 4a is provided with air vent 5, the described end of the air vent 5 on the upper bearing (metal) 4a that is formed on is connected with exhaust passage in being formed on upper bearing (metal) 4a, and the other end is connected with the inside of baffler 1a.
Working principle of the present invention is: by changing the structure of baffler 1a and upper bearing (metal) 4a, make gas after overcompression, enter silencing apparatus 1a, owing to do not have opening on the silencing apparatus 1a, gas is discharged by the air vent in the upper bearing (metal) 4a 5, and then upwards mobile through the gap on upper bearing (metal) 4a both sides, reached the purpose that has reduced noise.
