Below with reference to the accompanying drawings describe the compressor 100 according to the utility model embodiment, compressor 100 can be applicable to compression refrigerant in air-conditioning system.
As shown in Figure 1, housing 1, motor 4 and compressing mechanism can be comprised according to the compressor 100 of the utility model embodiment.Wherein, compressing mechanism can be arranged in housing 1.There is in housing 1 oil sump 11, compressing mechanism be immersed in oil sump 11 at least partially, when compressor 100 works, the lubricant oil in oil sump 11 can lubricate compressing mechanism, to reduce the friction between each parts of compressing mechanism.
Compressing mechanism comprises main bearing 21, cylinder assembly, bent axle 3 and supplementary bearing 23.Main bearing 21 is located at the top of cylinder assembly and supplementary bearing 23 is located at the bottom of cylinder assembly, and bent axle 3 runs through main bearing 21, cylinder assembly and supplementary bearing 23 in the axial direction.Cylinder assembly comprises two cylinders 221 arranged in the vertical direction, thus is convenient to realize multistage compression to the refrigerant in compressing mechanism, improves the flow of the refrigerant of discharging from the exhaust port 225 of compressor 100.
Wherein it should be noted that, two cylinders 221 " on ", setting on D score direction is only exemplary illustration for Fig. 1, can not be interpreted as one restriction of the present utility model.For convenience of description, hereinafter for the description of other structure of two cylinders 221 and compressor 100, all exemplary illustration is carried out for the direction of "up" and "down".
Two cylinders 221 are corresponding with two eccentric parts 31 of bent axle 3 to be arranged, and that is, the cylinder 221 of top is corresponding with the eccentric part 31 of top to be arranged, and the cylinder 221 of below and eccentric part 31 correspondence of below are arranged.There is phase difference between two eccentric parts 21, thus, two eccentric parts 31 are in the axially not corresponding setting of bent axle 3.Such as, the phase difference between the eccentric part 31 of top and the eccentric part 31 of below is 180 °, and that is, the eccentric part 31 of top and the eccentric part 31 of below are arranged towards two contrary directions respectively on bent axle 3, as shown in Figure 1.
Each cylinder 221 has compression chamber and vane slot 2213, piston 222 is provided with in each compression chamber, be enclosed within the eccentric part 31 arranged corresponding to it outside piston 222, and can roll along the inwall of corresponding compression chamber, thus, no matter whether two pistons 222 roll along the inwall of respective compression chamber, between synchronization two pistons 222, there is phase difference all the time, and phase difference between two pistons 222 is identical with the phase difference between two eccentric parts 31.
Particularly, compression chamber has air aspiration cavity 2211 and exhaust cavity 2212, such as, the compression chamber of correspondence exhaust cavity 2212 and air aspiration cavity 2211 can be divided into when the piston 222 of top is close to the inwall rolling of corresponding compression chamber, also the compression chamber of correspondence exhaust cavity 2212 and air aspiration cavity 2211 can be divided into when the piston 222 of below is close to the inwall rolling of corresponding compression chamber.It should be noted that, air aspiration cavity 2211 is corresponding with suction port 226, and exhaust cavity 2212 is corresponding with exhaust port 225, thus is convenient to refrigerant and enters in compressor 100 and discharge from compressor 100.Such as, the suction port 226 that refrigerant after heat exchange can be passed through compressor 100 enters in the air aspiration cavity 2211 of the cylinder 221 of top and the cylinder 221 of below respectively, when two pistons 222 along respective compression chamber inwall roll with compression refrigerant time, refrigerant constantly increasing temperature and pressure in the exhaust cavity 2212 of correspondence, is discharged in the refrigerant flow compressor 100 from exhaust port 225 subsequently.
Slide plate 227 is located at movably in vane slot 2213 and tip (one end that slide plate 227 is nearest apart from cylinder 221 center of correspondence, such as, the lower end in Fig. 4) only supports with the periphery wall of corresponding piston 222.Such as, under the effect of spring force or gas force, the tip of the slide plate 227 of top is only against on the periphery wall of the piston 222 of top.Thus, when the piston 222 of top moves back and forth in compression chamber, corresponding slide plate 227 is thereupon mobile in corresponding vane slot 2213, thus realizes the compression to refrigerant in corresponding compression chamber.
Dividing plate 223 is provided with between two cylinders 221, dividing plate 223 have cavity 224 and the intercommunicating pore 228 be communicated with oil sump 11 by cavity 224, therefore, lubricant oil in oil sump 11 flows in cavity 224 by intercommunicating pore 228, because the thermal conductivity of lubricant oil is lower than the thermal conductivity of dividing plate 223, therefore, when compressor 1000 works, lubricant oil in cavity 224 can stop the heat transmission between two cylinders 221 to a certain extent, improve the effect of heat insulation of dividing plate 223, thus improve the air-breathing mass flow rate of compressor 100, improve the efficiency of compressor 100.
