Detailed Description

The technical solution in an exemplary embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention.

As shown in fig. 1, the structure of the existing compressor mainly includes a core 1, a casing 4, an inner exhaust pipe 2 connecting the casing 4 and the core 1, and a compression spring support 3, as described in the background art, in the vibration reduction method of the existing compressor, the vibration of the compressor can be reduced by reducing the rigidity of the compression spring support 3, but the too small rigidity of the compression spring support 3 will cause the amplitude of the core 1 to increase, the stress applied to the connection end of the inner exhaust pipe 2 and the casing 4 increases, the inner exhaust pipe 2 is easy to break, and the reliability of the compressor is reduced, and the current mode of reducing the rigidity of the compression spring support 3 has reached the bottleneck of vibration reduction.

In order to overcome the defects, the invention provides a compressor with a damping vibration absorption system, which comprises an inner exhaust pipe 2 and a machine core 1, wherein at least one damping vibration absorption system 5 is arranged between the inner exhaust pipe 2 and the machine core 1; the damping vibration absorption system 5 is arranged at the position where the vibration of the inner exhaust pipe 2 is large, so that the vibration of the inner exhaust pipe 2 can be absorbed to the maximum degree, and the damping vibration absorption system has a good vibration absorption effect. The damping vibration absorption system 5 comprises a first fixing component, a second fixing component and an elastic vibration absorption component, wherein the elastic vibration absorption component is respectively connected with the inner exhaust pipe 2 and the movement 1 through the first fixing component and the second fixing component.

The inner core 1 and the pressure spring support 3 of the compressor can be regarded as a mass spring damping vibration absorption system, and the inner exhaust pipe 2 is used for transmitting the vibration of the core to the shell component. When the compressor runs at a high rotating speed, the movement 1 is in an inertia zone from the aspect of vibration, and the vibration displacement of the movement 1 is small. The inner exhaust pipe 2 can also be seen as a mass spring damping vibration absorption system from the shape analysis, when the compressor runs at a high rotating speed, although the vibration displacement of the machine core 1 is very small, the inner exhaust pipe 2 vibrates very greatly, so that the force transmitted to the shell 4 is large, the damping vibration absorption system 5 in the invention connects the machine core 1 and the inner exhaust pipe 2, and can effectively reduce the vibration of the inner exhaust pipe 2, thereby reducing the transmission of the vibration to the shell 4 and reducing the noise of the refrigerator.

In other embodiments, the damping and shock absorbing system 5 can also be disposed between the housing 4 and the inner exhaust pipe 2, but the process is more difficult and costly than the process of disposing between the movement 1 and the inner exhaust pipe 2. The surface of the shell 4 is an arc surface, and if a part is fixed, the surface of the part is also required to be the arc surface, so that the processing cost is high; secondly, if the damping vibration absorption system 5 is arranged on the upper shell, the position precision is required to be very high when the damping vibration absorption system is arranged, and the assembly cost is high because the shell 4 is closed.
