Linear compressor

Abstract

The present invention relates to a linear compressor and is improved on the base of the prior linear motor assembly, the prior compressed cylinder, etc; stator loops in the motor are a left stator loop and a right stator loop with a machine shell as a centre in symmetrical distribution; the machine shell between two stator loops is fixed with a left annular magnetic circuit element and a right annular magnetic circuit element; a rotor part outside a spindle is used as an iron core; the inner surfaces of a left end closure and a right end closure are respectively provided with a protrusion for inserting into respective stator loop; two head faces of the iron core are respectively provided with a concave which is matched with the protrusion; in a natural state, two ends of rotor are respectively inserted to each stator loop in order that two side of the centre of the machine shell respectively form a left and a right magnetic circuits which are symmetrical and balance with each other. The structure, the magnetic circuits, the circuits, the load and the resistance are in symmetrical and balanced arrangement and the surface of the rotor is the iron core, as long as reverse current is galvanized to the left and the right stator loops, the rotor can be attracted to have forced resonant movement to realize the air compression smoothly; the invention has high integral working efficiency and low energy consumption.

Description

technical field [0001] The invention relates to a compressor, in particular to a linear compressor. Background technique [0002] Most of the traditional compressors are reciprocating compressors, which generally use ordinary rotary motors to compress the gas by driving the piston to reciprocate in the cylinder through the crank-link mechanism. When the piston performs a compression stroke, the suction valve is closed and the exhaust valve is opened. When the piston is in the suction stroke, the exhaust valve is closed and the suction valve is opened. The working compression ratio of this kind of compressor is small, and the structure is complex from rotary motion to linear motion, the efficiency is low, and the noise is large when the mechanical transmission mechanism is working. [0003] In response to the above situation, linear compressors have appeared on the market. Most of the existing linear compressors use a single stator coil structure. This kind of linear compre...

Problems solved by technology

Since the linear motor in this patent document adopts an asymmetric structure and uses a permanent magnet to realize the reset movement of the mover, it has the same defects as above

In addition, since the reciprocating pump compresses fluid, the compression characteristics of fluid are different from air, so the linear compressor with this magnetic circuit structure cannot achieve the purpose of compressing air.

[0006] To sum up, the existing linear compressors all have the disadvantages of low working efficiency and high energy consumption, so further improvements can be made
