Abstract

The invention relates to a linear compressor with variable resonant frequency, which includes a discharge muffler, a connecting frame, a front flange, a fixing frame, a magnet mounting frame, a rear flange, a resonance adjustment device, a base, a cylinder, a piston, a permanent The magnet, the coil, the discharge muffler, the connecting frame, the front flange, the rear flange, and the resonance adjustment device are fixed by bolts to form a compressor frame, and the compressor frame is installed on the base by a fixing frame, so that The linear compressor applies an alternating current to the coil to generate an alternating magnetic field force, and the piston is driven to perform reciprocating linear motion in the cylinder under the action of the alternating magnetic field force. The invention uses a resonance adjustment device to change the axial stroke and stiffness of the plate spring, thereby changing the resonance frequency of the linear compressor, and can still maintain the resonance state during the frequency conversion process of the linear compressor to achieve the purpose of energy saving.

Description

technical field [0001] The invention belongs to the technical field of linear compressors, and relates to a moving coil type linear compressor, in particular to a linear compressor with variable resonance 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 are gradually replacing traditional crank connecting rods with smaller volume 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 reciprocate linearly in the cylinder. When the input excitation is equal to the natural frequency of the linear compressor, the system generates Resonance, the energy consumptio...
