Abstract

The invention discloses a gas outlet structure of compressor, including a top bearing, a cylinder under the top bearing and with the cavity opposite to a gas outlet of the top bearing, and a rolling circle and the side wall of the gas outlet forms a slope structure able to exhaust smoothly high pressure gas. Because the invention changes the shape of the gas outlet of the top bearing, it makes the high pressure able to be smoothly exhausted, thus reducing the noise and simultaneously improving the property of compressor pump body, i.e. raising the operating efficiency of the compressor.

Description

The exhaust outlet structure of compressor

Technical field

The present invention relates to a kind of rotary compressor.The exhaust outlet structure that particularly relates to a kind of rotary compressor.

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.

Fig. 1 is the press part sectional arrangement drawing of existing rotary compressor, and Fig. 2 is the left view of Fig. 1.

As shown in Figure 1 and Figure 2, press part is made of following structure: with the circular cylinder 2 of suction pipe 5 connections; The upper bearing 1 and the lower bearing 7 of combining closely and in the bi-side of cylinder 2, being through with running shaft 6; With running shaft 6 is the center, and that carries out in cylinder 2 simultaneously that off-centre rotatablely moves rolls ring 4, and is provided with the compression volume that forms compression refrigerant gas when rolling ring 4 rotations with upper bearing 1, lower bearing 7.

The as above press part of the existing rotary compressor of Gou Chenging, after compressor was connected power supply, the running shaft 6 that the rotor banding dynamic pressure of motor part is gone in the rotor together rotated.Along with the rotation of running shaft 6, the eccentric part that running shaft 6 lower ends form and roll ring 4 rotations 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 2.Export by valve member through as above process compressed refrigerant, export the inside of seal container to, outputing to the outside through the slit between rotor and the stator by output tube afterwards by the through hole of baffler.

The rotary compressor press part is the cardiac component that produces compression process, also is the main source that noise and vibration produce.When existing compressor operating, the pressurized gas that produces is discharged by relief opening 3 places of upper bearing 1, because relief opening 3 and cylinder 2 have an angle, when pressurized gas are discharged, produce flow-disturbing in the angle, cause the disorder of pressurized gas, as shown in Figure 2, produce noise, influence compressor operating efficient.

Summary of the invention

Technical problem to be solved by this invention is, provides a kind of by improving the shape of upper bearing relief opening, makes the pressurized gas can clear and coherent discharge, reduces because pressurized gas change direction produces the exhaust outlet structure of the compressor of noise.

The technical solution adopted in the present invention is: a kind of exhaust outlet structure of compressor, include upper bearing, be positioned at the relief opening corresponding cylinder of the downside of upper bearing and its cavity and upper bearing and roll ring and constitute, the sidewall of the relief opening of its upper bearing forms and can make the clear and coherent ramp structure of discharging of pressurized gas.

The present invention is owing to changed the shape of upper bearing relief opening, thereby make the discharge that pressurized gas can be clear and coherent, thereby reduce to have improved the performance of compressor pump simultaneously, also promptly improved the operational efficiency of compressor because pressurized gas produce noise because of resistance changes direction when discharging.

Embodiment

Provide specific embodiment below in conjunction with accompanying drawing, further specify the present invention and how to realize.

As shown in Figure 4, the exhaust outlet structure of compressor, include upper bearing 11, be positioned at relief opening 13 corresponding cylinder 2 of the downside of upper bearing 11 and its cavity and upper bearing 11 and roll ring 4 and constitute, the sidewall of the relief opening 13 of its upper bearing 11 forms and can make the clear and coherent ramp structure of discharging of pressurized gas.The sidewall of the relief opening 13 of described upper bearing 11 and the sidewall of cylinder cavity form 180 ° angle.

Like this, when compressor operating, the pressurized gas that produces is discharged by relief opening 13 places of upper bearing 1, because the sidewall of relief opening 13 is a ramp shaped, and with the angle of cylinder chamber body sidewall be 180 °, when pressurized gas are discharged, do not produce flow-disturbing in the angle, pressurized gas are discharged smoothly, promptly improved the operational efficiency of compressor.

Claims

1. the exhaust outlet structure of a compressor, include upper bearing (11), be positioned at relief opening (13) corresponding cylinder (2) of the downside of upper bearing (11) and its cavity and upper bearing (11) and roll ring (4) and constitute, it is characterized in that the sidewall of the relief opening (13) of upper bearing (11) forms and can make the clear and coherent ramp structure of discharging of pressurized gas.
