Embodiment Construction

[0030] figure 1 is a schematic sectional view of a linear compressor according to an embodiment of the present invention. Such as figure 1 As shown, the embodiment of the present invention provides a linear compressor. Linear compressors can be used in vapor compression refrigeration cycle systems, such as refrigerators or freezers, for compressing refrigerants.

[0031] The linear compressor of the embodiment of the present invention may generally include a casing 100 , a linear motor 700 , a cylinder 200 , a piston 300 and at least one spring mass damping module 500 .

[0032] The casing 100 defines an accommodating cavity, and is installed with an air suction pipe (not shown) and an exhaust pipe (not shown). The linear motor 700 is installed in the casing 100 and includes a stator 720 and a mover 710 . The stator 720 is directly or indirectly fixed to the casing 100 . When the linear motor 700 is energized and running, an electromagnetic force is generated between the ...

Abstract

The invention provides a linear compressor. The linear compressor comprises a shell, a linear motor including a stator and a mover, a cylinder defining a space for compressing a refrigerant, a pistondriven by the mover to perform linear reciprocating motion in the axial direction of the linear motor so as to compress the refrigerant in the cylinder, and at least one spring mass damping module including an elastic member connected to the mover and a mass connected to the elastic member and used for damping axial vibration of the linear compressor. The linear compressor can effectively reduce axial vibration, and is simple and reliable in structure.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a linear compressor. Background technique [0002] A damping spring is usually arranged between the bottom of the pump body and the bottom wall of the inner shell in the piston compressor to absorb the vibration of the compressor. [0003] The linear compressor is a piston compressor using a linear motor. The linear motor includes a stator and a mover. The mover performs linear reciprocating motion in the axial direction, which makes the axial vibration of the linear compressor relatively large. Moreover, since the axial direction of the mover is usually parallel to the horizontal direction, the vertically extending damping spring has little effect on absorbing the axial vibration of the compressor. Contents of the invention [0004] The object of the present invention is to provide a linear compressor capable of effectively reducing axial vibration. [0005] A further ob...
