Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
Preferred embodiment:
This preferred embodiment discloses a kind of compressor, specially a kind of rotor-type compressor.As depicted in figs. 1 and 2, the pressure
Contracting machine includes hollow shell, and shell includes the upper housing 1 being connected and lower case 2；Upper housing 1 is hollow column knot
Structure, lower case 2 are hollow frustum structure；The area at the upper bottom of lower case 2 is less than the area of its bottom, the upper bottom of lower case 2
It is connected with upper housing 1.
It is hollow frustum structure by upper housing 1 and lower case 2 and lower case 2 that housing design is segmented, increases
The intracorporal space of shell, the height for reducing pump assembly, decline the center of gravity of compressor, and the rotation for increasing compressor entirety is used
Amount and stability, can effectively mitigate the vibration of compressor；The area of lower part of the housing becomes larger, and improves the flat of compressors cylinder
Graduation degree, and then improve the refrigerating capacity of compressor；The space of lower part of the housing becomes larger, and can expand the discharge capacity of compressor.
Upper housing 1 can be but be not limited to cylindric, and lower case 2 can be but be not limited to circular cone shape.Lower case 2
Side wall and horizontal plane between angle β be more than or equal to 30 ° and less than 90 ° that is, angle β section [30 °, 90 °) in, specific number
Value is depending on the size of device in compressor.
Upper housing 1 and lower case 2 can be integrally formed, and be also possible to weld or rivet again together after processing respectively.
Shell can be formed by way of winding, welding, and can also be formed using other way, do not influence upper housing 1 and lower case 2 it
Between bonding strength.
Compressor further includes stator 3 and cylinder 4；Stator 3 is mounted in upper housing 1, and cylinder 4 is mounted in lower case 2.Its
In, stator 3 cooperates process Installation in upper housing 1 by hot jacket, and connection more fastens, and installation effectiveness is higher.
On the basis of above structure, cylinder 4 is flat cylinder or huge discharge cylinder, effectively improves the refrigeration energy of compressor
Power.
