AI Technical Summary

Problems solved by technology

This is because the piston of the linear compressor is rigidly connected to the mover, which cannot ensure that the piston is located at the center of the stator, so that the piston generates a large lateral force on the cylinder, resulting in an increase in frictional power consumption and a decrease in mechanical efficiency

Embodiment Construction

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

Abstract

Provided is a linear compressor comprising a cylinder, a piston, a cylinder shell, a linear motor stator, a magnetic levitation bearing and a mover. One end of the cylinder shell is sleeved on the cylinder, and another end of the cylinder shell is provided with a mounting cavity communicating with the cylinder cavity. A cavity wall of the mounting cavity is respectively provided with a stator mounting groove and a protrusion in a circumferential direction thereof. The linear motor stator is mounted in the stator mounting groove. The magnetic levitation bearing is disposed on the cavity wall of the mounting cavity. The mover includes a mover rod and a magnetic member disposed on the mover rod, and the mover rod is connected with the piston. The use of magnetic levitation bearing can avoid mechanical friction caused by direct contact of the mover with the linear motor stator.

Description

technical field [0001] The invention relates to the technical field of gas compression equipment, in particular to a linear compressor. Background technique [0002] Most of the household refrigeration compressors widely used at present are rotary compressors, and the motors of the rotary compressors drive the pistons to reciprocate. However, the inertial force and rotational friction generated by the unbalanced rotating mass of the crank and the movement of the connecting rod will inevitably cause power loss. The traditional linear compressor only needs a friction pair of cylinder and piston, and the driving direction of the piston is on the same straight line as the direction of motion, so the corresponding frictional power loss should be small. The currently used reciprocating piston compressor has four sets of friction pairs, so in theory the mechanical efficiency of the linear compressor is much higher than that of the reciprocating piston compressor, but it is not the...
