Problems solved by technology

However, during the reciprocating movement of the piston, only one-way is useful work, and the return journey is useless work. Chinese Patent No. 200720087539.0 discloses a double-cylinder electromagnetic compressor, which can perform useful work when the piston reciprocates. However, the technology disclosed in the above-mentioned patent In the scheme, resonant springs are arranged at both ends of the casing, and the two coils are arranged in the middle of the casing. In actual use, due to the short distance between the two coils, the coils are likely to interact with each other after being energized, and the magnetic field saturation is prone to occur. reduce the efficiency of the compressor

Abstract

The invention provides a straight-line compressor. The straight-line compressor comprises a shell, a mover and resonance springs, wherein the mover and the resonance springs are arranged in the shell.Stators are correspondingly arranged at the two ends of the shell. A coil is arranged on each stator. A cylinder is arranged on each stator. Pistons corresponding to the cylinders are arranged on themover. The pistons are slidably arranged in the corresponding cylinders. Permanent magnets corresponding to the stators are arranged on the mover. The resonance springs are arranged between the moverand the corresponding stators. By the adoption of the straight-line compressor, the whole structure of the straight-line compressor is simplified, quick assembly is facilitated, and the motor efficiency of the straight-line compressor is improved.

Description

technical field [0001] The invention relates to a compressor, in particular to a linear compressor and a control method thereof. Background technique [0002] At present, there are two types of compressors used in refrigeration equipment, rotary and linear. The linear compressors in the prior art usually include shells, stators, coils, movers, pistons, cylinders, spring back baffles and springs. wherein, the mover is provided with a magnet, the magnet is inserted into the magnetic field space formed by the stator, a coil is placed in the stator, one end of the piston is connected to the mover, and the other end of the piston is inserted into the inner cavity of the cylinder. During use, the coil is energized to generate an alternating magnetic field to drive the mover to drive the piston to reciprocate at high frequency. However, during the reciprocating movement of the piston, only one-way is useful work, and the return journey is useless work. Chinese Patent No. 200720087...
