The working procedure of above-mentioned rotary compressor is as follows:
Give stator 2 power supplies, make the inner rotation of rotor 3 at stator 2, meanwhile running shaft 4 rotates and piston 7 off-centre in cylinder 5 is rotated, along with the off-centre rotation of rolling ring 7, refrigeration agent is inhaled into the breathing space of cylinder 5, and continues to be compressed to certain pressure, when the pressure in the compression volume of cylinder 5 surpasses critical pressure, the drain tap 8 that is installed on the relief opening of upper bearing (metal) 6A is opened, and pressurized gas drains in the housing 1 through drain tap 8 and baffler 9 from compression volume.The gas of discharging enters into the top of rotary compressor by the slit between the slit between housing 1 and the stator 2 or stator 2 and the rotor 3, passes through gas outlet pipe DP then and is discharged to the circulating frozen system.
But there is following shortcoming in existing rotary compressor:
Liquid container belongs to overhang away from housing, can cause the vibration of tube structure big after installing to compressor in the air-conditioning, and noise is big.In addition, do not have heat exchange between liquid container and the motor, the temperature height of motor, efficient are low, and the temperature of liquid container is lower, and the fluid separating effect is bad.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of rotary compressor that improves the fluid separating effect and reduce noise when improving electric efficiency.
For this reason, technological scheme of the present invention is as follows:
A kind of rotary compressor, the motor that comprises housing, is arranged on the press part that in the housing cold media air is compressed and is used for the work of drive compression portion, described housing is a double layer construction, form by inner and outer wall, interlayer between the described inner and outer wall forms gas flow space, one side is formed with shell air inlet on the top of outer wall, and one side is formed with the press part suction port in the bottom of inwall, and the outer circumferential face of inwall is provided with a plurality of radiating fins.
Preferably, described shell air inlet and press part suction port lay respectively at the both sides at described housing.
Described a plurality of radiating fin is upper and lower in a circumferential direction to be crisscross arranged, and radiating fin is consistent with gas flow direction in the liquid container in the trend of circumferencial direction, radiating fin be shaped as waveform.
Rotary compressor of the present invention, gas enters in the double Shell from shell air inlet, flow to the cylinder intakeport through inner flow passage, radiating fin has increased the heat transfer process between gas and the motor, the high temperature of motor conducts to the gas in the double Shell, has so both cooled off motor, has increased electric efficiency, heat mixed gas again, improved the separating effect of fluid in the mixed gas.In addition, liquid container and housing form an integral body, have reduced the vibrations of liquid container, have reduced noise.

Embodiment
Be elaborated below in conjunction with the structure of accompanying drawing to rotary compressor of the present invention.
At first as shown in Figures 2 and 3, the internal structure of rotary compressor of the present invention and existing rotary compressor is basic identical, comprising: be arranged in the housing 21 and have the compressor of eccentric part running shaft 24, the press part that is used for cold media air is compressed, be separately positioned on press part the upper bearing (metal) 26A of both sides and lower bearing 26B and the motor driving part that is used for drive compression portion up and down.Wherein, described press part comprises: be fixedly installed on circular cylinder 25 on housing 21 inner peripheral surfaces, be arranged on the eccentric part of running shaft 24 and under the effect of running shaft 24 in cylinder 25 ring 27 and one end that rolls of eccentric rotation be crimped on the outer circumferential face that rolls ring 27, the other end contacts with baffle plate spring (not shown), and is rolling the baffle plate 28 of doing straight line motion when ring 27 is rotated motion and cylinder 25 being divided into breathing space and compression volume.Described motor driving part comprises: be arranged on the motor stator 22 and the rotor 23 of the inside of housing 21, the center of described rotor 23 is pressed into and is installed on the running shaft 24.In addition, be provided with outlet pipe DP on the top of housing 21.
Referring to Fig. 3 and Fig. 4, in order to reduce the temperature of motor, and improve the fluid separating effect of gas in original compressor liquid storage can, replace original liquid container with double Shell 21 in the present invention.Described housing 21 is made up of inwall 21B and outer wall 21A, and the interlayer between inwall 21B and outer wall 21A forms gas flow space.In addition, one side is formed with the shell air inlet (not shown) on the top of outer wall 21A, one side is formed with press part suction port 29 in the bottom of inwall 21B, enters gases in the double Shell 21 from the shell air inlet on top and enters in the cylinder 25 from press part suction port 29 after through the runner that forms in the double Shell and compress.Preferably, shell air inlet and press part suction port 29 lay respectively at the both sides of inner walls 21B, enter cylinder again after entering the whole wall that gas in the double Shell can flow through inwall 21B like this, make heat exchange more abundant.In addition, in order to improve heat exchange efficiency, the outer circumferential face of inwall 21B is provided with a plurality of radiating fins 30.A plurality of radiating fins 30 are upper and lower in a circumferential direction to be crisscross arranged, and radiating fin 30 is consistent with gas flow direction in the liquid container in the trend of circumferencial direction.The shape of radiating fin 30 can be a waveform as shown in FIG., also can be other suitable shape.
After gas enters double Shell from shell air inlet, in the space between double Shell, flow to press part suction port 29 directions downwards around the inwall 21B of double Shell.In flow process, gas fully contacts with radiating fin 30 with inwall 21B, enters the press part suction port 29 that is positioned at the bottom after heat exchange.In this process, the high temperature of motor conducts to the gas in the double Shell, makes motor obtain cooling, thereby has increased electric efficiency; On the other hand, the refrigerant gas of the lubricant mist of having carried under one's arms is heated, and has improved the separating effect of fluid in the mixed gas.The lubricant oil that is separated is slowly assembled the back and is dropped to bottom in the double Shell from radiating fin, and when the lubricant oil liquid level that accumulates in the bottom was higher than press part suction port 29, lubricant oil entered compressor inside with gas, and compressor is lubricated.
