Abstract

The invention provides a volume adjustable linear compressor and a control method thereof. The volume adjustable linear compressor comprises a shell, a stator, a piston, an air cylinder, a rotor, a spring and a rear baffle and also comprises a magnetic assembly; the stator, the piston, the air cylinder, the rotor, the spring and the rear baffle are arranged in the shell; the magnetic assembly 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 rotate along with the rotor; and a magnetic force generated between the first magnetic part and the second magnetic part is used for regulating a position where the rotor is in a force balancing state. The reliability of the linear compressor is improved.

Description

technical field [0001] The invention relates to a compressor, in particular to a volume-adjustable 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. Linear compressors in the prior art usually include a casing, a stator, a coil, a mover, a piston, a cylinder, a tailgate, a spring and other components; 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 arranged in the inner cavity of the cylinder, and the outer casing There is also a suction tube on it. Chinese Patent No. 2009100769408 discloses a fixed clearance device for variable capacity adjustment of a linear compressor, which uses an actuator to adjust the position of the exhaust plug to change the volume of the cylinder...
