Description
Technical field
The utility model belongs to hermetic rotary compressor, particularly relates to a kind of cabinet of the hermetic rotary compressor that cabinet and cylinder block are pressed together and the fixed structure of cylinder block.
Background technique
Generally speaking, freezing cycle device is according to connecting tube, compressor, condenser, expansion gear, vaporizer is connected to constitute in order.Also discharge behind compressor suction, the compression refrigerant gas, according to the mode of pressurized gas, it is divided into all kinds such as rotary compressor, reciprocal compressor, scroll compressor.The formation of compressor be by; Be arranged on seal container and the interior motor that produces driving force of seal container with certain inside space, obtain the driving force of motor, the cylinder block of pressurized gas constitutes.
Fig. 1 is a profile diagram of showing rotary compressor.Fig. 2 and Fig. 3 are welded profile diagram and the cross-section profiles of showing the cylinder block of rotary compressor.
Identical as shown in the figure, hermetic rotary compressor is equipped with the motor 4 that is formed by rotor 2 and stator 3 in the inside of seal container 1, and running shaft 5 is pressed into, be fixed on and be positioned on axis hole 2a rotor 2 centers, that form by Vertical direction.
Be formed with whole eccentric part 6 on the underpart of running shaft 5, be inserted with rotating piston 7 on the outside of its eccentric part 6, and the compressor cylinder assembly 12 that is formed by cylinder block 9, upper and lower part bearing 10,11 is installed, when its rotating piston 7 is rotated, form the compression volume 8 of compression refrigerant.
The outlet side of the 10a that portals that forms on upper bearing 10 is equipped with valve assembly body 15, is equipped with on the top of its valve assembly body 15 to reduce the baffler 16 of discharging noise.
On the suction port 9a side of cylinder block 9, be communicated with the storage 17 that is mounted with the inflow that prevents liquid coolant, the discharge tube 18 that compressed high pressure refrigerant gas in compressor cylinder assembly 12 is discharged to the outside is installed above the seal container 1.
If power supply is connected as above on the hermetic rotary compressor that constitutes, just the rotor 2 of motor 4 is rotated, and its running shaft 5 that is pressed in the rotor 2 also is rotated.And, with last identical, if utilize the rotation of running shaft 5, the eccentric part 6 that forms on the underpart of running shaft 5, the rotating piston 7 that is combined on its eccentric part 6 is rotated, by the suction port 9a of cylinder block 9, be the compressing refrigerant gas of the low-temp low-pressure state that is inhaled into compression volume 8 inside the cold media air of high-temperature high-pressure state.
In addition, compressed cold media air is discharged by valve assembly body 15, pass through hole 16a to the discharge of the inside of seal container 1 by baffler 16.The cold media air of the High Temperature High Pressure that is discharged from passes through the slit between rotor 2 and the stator 3, and is discharged to the outside by discharge tube 18.
In compressor, the welding that the cabinet 1a of seal container 1 is carried out; Identical as shown in Figures 2 and 3, cabinet 1a and cylinder block 9 usefulness 3 spot welding are fixed up.
In the drawings, the 19th, zoning blade, w are weld parts.
But if weld cabinet 1a and cylinder block 9 with old-fashioned mode, when welding, heat affecting that is produced and stress are concentrated the distortion that can cause internal diameter, therefore, when compression operation, have the problem of rushing down the efficient reduction that is caused because of leakage.
Summary of the invention
