Linear compressor

Abstract

The invention discloses a linear compressor. The linear compressor comprises a shell, an air cylinder, a piston, a linear motor, a stator spring plate, a rotor framework, a vibration reduction rotor, a spring set connecting piece, a first spring set, a second spring set, a third spring set and a fourth spring set. The first spring set is arranged between the stator spring plate and the rotor framework, the second spring set is arranged between the rotor framework and the spring set connecting piece, and the third spring set is arranged between the spring set connecting piece and the vibration reduction rotor. The fourth spring set is arranged between the vibration reduction rotor and the shell. The linear compressor has the beneficial effects that 1, the fault of the linear compressor due to the unstable problem of springs is avoided, and the reliability of the linear compressor is improved; 2, the types of the springs are reduced, so that the design of the linear compressor is simpler; and 3, a structure that the shell of the linear compressor is separated from a main pump body is abandoned, so that the linear compressor is more compact in structure and easy to miniaturize. Furthermore, the cost of the linear compressor is reduced, and the competitiveness of the linear compressor is improved.

Description

technical field [0001] The invention belongs to the technical field of reciprocating compressor structures, in particular to a linear compressor with a damping structure. Background technique [0002] Generally speaking, a compressor is a mechanical device that uses the power provided by a motor to compress low-pressure gas into high-pressure gas. It is widely used in household appliances such as refrigerators and air conditioners, or in many industries. Among them, the reciprocating compressor forms a compression space between the piston and the cylinder for sucking or exhaling the working gas, and uses the piston to perform linear reciprocating motion inside the cylinder to compress the refrigerant. The traditional reciprocating compressor is driven by a rotary motor, and the rotor of the motor is connected to the piston by a motion conversion device such as a crankshaft connecting rod, so as to convert the rotary motion of the motor into linear motion to achieve the above...

Problems solved by technology

Therefore, it can be seen that, on the one hand, figure 2 The linear compressor shown requires at least two different coil springs as resonance springs; on the other hand, it is very difficult to design a coil spring with a slender shape like the middle spring, and it is difficult to ensure the axial direction of the coil spring during processing. Straightness, so the spring tends to bend sideways in the middle when compressed

If such a spring is used as the resonance spring of the linear compressor, the linear compressor is very prone to failure during operation, so the reliability is poor
