Description
Technical field
The invention relates to rotary compressor, particularly a kind of air suction structure of rotary compressor.Promptly improve the air suction structure of rotary compressor, prevent because the distortion that welding causes and the generation of impurity.
Background technique
In general, rotary compressor does not rely on centrifugal force, but by the rotation of running shaft in the cylinder refrigerant is compressed, and the ring that rolls that promptly is installed in the off-centre of bent axle bottom is done rotation and revolution motion along the inner peripheral surface of cylinder, and refrigerant is sucked and compression.
As shown in Figure 1, rotary compressor forms confined space in inside, comprising: the seal container 10 that is provided with intakeport 1 and relief opening 2; Be located at the motor part 20 of the inside of seal container 10; Be located at the inside of seal container 10, and link to each other with motor part 20 and drive, will suck refrigerant compressor for compressing portion 30; On the intakeport 1 that seal container 10 links to each other, the liquid storage that communicates with compressor section 30 irritates 40.
Certain position of upper bearing 32 is provided with the exhaust port 32a that compression refrigerant is discharged, and after the pressure that also is provided with compression refrigerant on the exhaust port 32a acquired a certain degree, with the outlet valve that refrigerant is discharged, the top of upper bearing 32 also was provided with the baffler 38 that reduces exhaust noise.
As shown in Figure 2, the structure of intakeport comprises: be inserted in the cutting ferrule 45 on the intakeport 1 of seal container 10; Be inserted in the inside of cutting ferrule 45, the interior cutting ferrule 46 that links to each other with suction passage 35a; The inside of cutting ferrule in being inserted in clings to clip 47 on the suction passage 35a with interior cutting ferrule 46.In sucking pipe 44 inserts behind the cutting ferrule 46, cutting ferrule 45, interior cutting ferrule 46 and sucking pipe 44 welds simultaneously fixing, and formation weld part 48.
Above-mentioned rotary compressor is connected power supply, by interaction running shaft 31 rotations of stator 21 and rotor 22; Be located at the eccentric part 31a rotation of running shaft 31 1 sides, drive the ring 36 that rolls that contacts with blade 37 in the inside of cylinder 35 and rotate; The rotation of rolling ring 36 is compressed into the refrigerant of high temperature, high pressure with the low temperature of liquid storage filling 40 suctions, the refrigerant of low pressure, wherein, the refrigerant of irritating low temperature that 40 its impurities and liquid coolant be filtered, low pressure by liquid storage after the inside of cylinder 35 sucks, is compressed into the refrigerant of high temperature, high pressure through sucking pipe 44 and intakeport 1 and suction passage 35a.
After the refrigerant of the compressed high temperature in the inside of cylinder 35, high pressure is pushed outlet valve open, discharge by exhaust port 32a; The refrigerant of discharging is discharged by the relief opening 2 that is formed on the side cover 12 again through the inside of baffler 38 by seal container 10.
But, the rotary compressor of existing structure, when welding was inserted in sucking pipe 44 on the cutting ferrule 46, welding flame can permeate inside by the slit of cutting ferrule 46 and sucking pipe 44, thereby formed black stain in inside or produce thermal distortion.
Summary of the invention
The present invention is in order to overcome the problem that above technology exists, a kind of air suction structure of rotary compressor to be provided, and purpose is, improves the air suction structure of rotary compressor, prevents the generation and the thermal distortion of foreign body.
To achieve these goals, the technical solution used in the present invention is: comprising: comprising: cylinder is arranged on the inside of the seal container that has intakeport and relief opening, be formed with the suction passage of perforation with radiation shape in the inside of press part, cutting ferrule is inserted on the intakeport, and interior cutting ferrule is inserted in the inside of cutting ferrule, and links to each other with suction passage, the inside of cutting ferrule in one side end is inserted in, thereby the clip of the associativity of cutting ferrule in improving, sucking pipe is plugged on the other end of clip, the drainage refrigerant.
Effect of the present invention is as follows: stream has the sucking pipe of refrigerant to be inserted on the outer circumferential face of clip, contact with interior cutting ferrule, and cutting ferrule, interior cutting ferrule and sucking pipe is welded on the outer circumferential face of clip simultaneously.Thereby prevent that welding flame is penetrated into the inside of sucking pipe and clip, and then prevent the generation and the thermal distortion of impurity.
