Abstract

The invention relates to a linear compressor with variable resonant frequency. The linear compressor comprises a discharge silencer, a connecting frame, a front-end flange plate, a fixing frame, a magnet mounting frame, a rear-end flange plate, a resonance adjusting device, a base, an air cylinder, a piston, a permanent magnet and a coil, wherein the exhaust silencer, the connecting frame, the front-end flange plate, the rear-end flange plate and the resonance adjusting device are fixed through bolts to form a compressor rack, the compressor rack is installed on the base through the fixing frame, the linear compressor applies alternating current to the coil to generate alternating magnetic field force, and the piston is driven to do reciprocating rectilinear motion in the air cylinder under the action of alternating magnetic field force. The resonance adjusting device is used for changing the axial stroke and rigidity of a plate spring, so that the resonance frequency of the linear compressor is changed, the resonance state of the linear compressor can still be kept in the frequency conversion process, and the purpose of saving energy is achieved.

Description

technical field [0001] The invention belongs to the technical field of linear compressors, and relates to a moving coil linear compressor, in particular to a linear compressor with variable resonant frequency. Background technique [0002] As the heart of refrigeration equipment, compressors are widely used in white goods such as air conditioners, refrigerators, and freezers. With the continuous development of science and technology, linear compressors gradually replace traditional crank connecting rods with smaller volumes and lower energy consumption. The market for reciprocating compressors. The linear compressor generates an alternating magnetic field force by applying an alternating current to the coil. Under the action of the alternating magnetic field force, the piston is driven to make a reciprocating linear motion in the cylinder. When the input excitation is equal to the natural frequency of the linear compressor, the system generates Resonance, at this time, the ...
