Abstract

The invention provides a control method for automatically changing the volume of an air cylinder of a linear compressor. The linear compressor comprises a shell and further comprises a stator, a piston, the air cylinder, a rotor, a spring and a rear baffle, all of which are arranged in the shell. A magnetic assembly is further included and comprises a first magnetic part and a second magnetic part. The first magnetic part is fixed relative to the shell, the second magnetic part can move along with the rotor, and magnetic force generated between the first magnetic part and the second magnetic part is used for adjusting the position where the rotor is in a force balance state. The control method comprises the first step of top dead center detection and the second step of air cylinder volume adjustment. The reliability of the linear compressor is improved.

Description

technical field [0001] The invention relates to a compressor, in particular to a control method for automatically changing the cylinder volume of a linear compressor. Background technique [0002] At present, there are two types of compressors used in refrigeration equipment: rotary type and linear type. The linear compressors in the prior art usually include shells, stators, coils, movers, pistons, cylinders, tailgates, springs and other components; Among them, 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, the head of the piston is slidably set in the inner cavity of the cylinder, and the outer shell An aspirator is also arranged on the top. Chinese Patent No. 2009100769408 discloses a constant clearance device for variable capacity adjustment of a linear compressor, which uses an actuator to adjust the position of the exhaust p...
