Linear compressor

Abstract

The invention a linear compressor of adjustable induction coefficient according to the variation of load, which is characterized by the following: the fixation part contains compression space; the mobile part is fixed in the fixation part to do reciprocal line movement along the axial direction, which compresses the sucked coolant in the compression space; at least one spring supports the mobile part, which changes the spring coefficient according to the load; the linear motor connects and activates the mobile part, which changes the operation frequency fc according to the adjusted induction coefficient.

Description

technical field [0001] The present invention relates to a linear compressor (LINEAR COPMRESSOR); in particular to a linear compressor that adjusts the inductance to make the operating frequency vary according to the load Background technique [0002] Generally speaking, a compressor (Compressor) is a device that compresses air or refrigerant or other various working gases after obtaining power from a power generating device such as a motor or a turbine, thereby increasing the pressure of the above gases. Here, the above-mentioned compressors are commonly used in general household appliances such as air conditioners and refrigerators, or in manufacturing fields. [0003] Compressors can be divided into: A reciprocating compressor (reciprocating compressor) that compresses the refrigerant by forming a compression space for sucking / discharging working gas between the piston (Piston) and the cylinder (Cylinder) and making the piston perform linear reciprocating motion inside the...

Problems solved by technology

[0024] However, in the low load region, the natural frequency f of the above-mentioned piston n will be less than the operating frequency f of the above linear motor c , so the above-mentioned piston will move excessively to a position above the similar point, so not only will there be excessive compression force, but also friction and wear of the above-mentioned piston and cylinder will occur, and because it does not operate under resonance, the efficiency of the compressor will be reduced. reduce

[0025] Also, in the high load region, due to the above natural frequency f of the piston n will be greater than the operating frequency f of the above linear motor c , so the above mentioned piston cannot run to a similar point, resulting in a reduction in the compression force

And can reduce compressor efficiency by not being able to operate at resonance

[0026] Therefore, in conventional linear compressors, the natural frequency f of the piston changes due to load changes. n changes, due to the operating frequency of the linear motor f c It is certain, so the above-mentioned linear motor cannot operate in a resonance state, resulting in a decrease in its efficiency. In addition, the problem that the load cannot be unloaded quickly due to the inability to actively control the load
