Abstract

The invention provides a controlling method for air cylinder volume changing of a linear compressor. The linear compressor comprises a shell, a stator, a main coil, a piston, an air cylinder, a rotor, a spring and a rear baffle, wherein the stator, the main coil, the piston, the air cylinder, the rotor, the spring and the rear baffle are arranged in the shell. A permanent magnet is arranged on the rotor. The controlling method for the air cylinder volume changing of the linear compressor is characterized in that the rotor is further provided with a secondary coil, and the secondary coil is used for selectively overlaying or offsetting magnetic field strength generated by the main coil; and the controlling method comprises the first step of detecting an upper dead point and the second step of adjusting the cylinder volume. According to controlling method for the air cylinder volume changing of the linear compressor, efficiency and reliability of the linear compressor are improved.

Description

technical field [0001] The invention relates to a compressor, in particular to a control method for variable volume of a cylinder 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 plug to change...
