Description
Technical Field
[0001] The present application relates to the technical field of air conditioning, and in particular to a compressor assembly and an air conditioner. Background Art
[0002] As the core power device of the air conditioning refrigeration system, the operating stability of the compressor directly affects the reliability of the air conditioning and the user's comfort experience. The compressor will inevitably vibrate during operation. The vibration source comes from the vibration generated during the operation of its own rotor or piston, and from the unstable vibration imposed on the compressor by the external working environment. Vibration will cause abnormal sound and noise, thereby reducing the user's comfort level for the product. Therefore, it is necessary to take vibration reduction or vibration absorption measures to reduce vibration and improve the stability of the compressor operation process.
[0003] The general vibration reduction method is to install vibration-damping pads on the compressor base to consume and attenuate vibration energy, or to wrap the compressor tightly with sound insulation cotton to absorb or reduce the noise caused by vibration. However, the compressor will produce unstable vibration or shaking under unstable working conditions (such as car air conditioners, ship air conditioners) or when encountering harsh external operating environments (such as bumpy mud roads) during transportation. This unstable vibration excitation acts on the compressor body, causing the compressor to shake significantly in the axial and longitudinal directions inside the air conditioner, making it difficult for the vibration reduction structure of the compressor to meet the vibration reduction requirements under unstable working conditions or harsh external environments. Summary of the invention
[0004] Therefore, the technical problem to be solved by the present application is to provide a compressor assembly and an air conditioner, which can improve the vibration reduction performance of the compressor under unstable working conditions or in harsh external environments and ensure the smooth operation of the compressor.
[0005] In order to solve the above problems, the present application provides a compressor assembly, including a chassis, a compressor body, a first vibration damping structure and a second vibration damping structure. The first vibration damping structure is connected between the chassis and the compressor body, and provides a vibration damping force in a radial direction for the compressor body. The second vibration damping structure is connected between the chassis and the compressor body, and provides a vibration damping force in an axial direction for the compressor body.

[0016] Preferably, in a cross section perpendicular to the central axis of the compressor body, the foot pads and the cylinders are arranged in one-to-one correspondence, and the projection of the center line of the corresponding foot pad and the projection of the central axis of the compressor body are located on the center line of the cylinder.
[0017] According to another aspect of the present application, an air conditioner is provided, comprising a compressor assembly, which is the above-mentioned compressor assembly.

[0024] See also Figures 1 to 3 As shown, according to an embodiment of the present application, the compressor assembly includes a chassis 1, a compressor body 2, a first vibration damping structure and a second vibration damping structure, the first vibration damping structure is connected between the chassis 1 and the compressor body 2, and provides a vibration damping force in a radial direction for the compressor body 2, and the second vibration damping structure is connected between the chassis 1 and the compressor body 2, and provides a vibration damping force in an axial direction for the compressor body 2.
[0025] The compressor body 2 performs vibration reduction in the radial direction through the first vibration reduction structure, and performs vibration reduction in the axial direction through the second vibration reduction structure. Therefore, the first vibration reduction structure and the second vibration reduction structure can simultaneously reduce vibration in the axial and radial directions of the compressor body 2, thereby reducing the excitation effect of unstable vibration or shaking on the compressor body 2, so that the compressor body 2 can form good adaptability in the axial and radial directions of the air conditioner, thereby improving the vibration reduction performance of the compressor under unstable working conditions or harsh external environments, and ensuring the smooth operation of the compressor.
[0026] The first vibration reduction structure includes a cylinder 3 and a piston 4 slidably disposed in the cylinder 3, and the end of the piston 4 is connected to the compressor body 2. The piston 4 can move relative to the cylinder 3, and a gas is stored in the cylinder 3. The gas has strong compressibility and buffering properties, so the cylinder can be used to form a buffering effect on the radial vibration of the compressor body 2, thereby reducing the radial vibration on the compressor body 2.
[0027] In one embodiment, the piston 4 is connected to the compressor body 2 through an elastic member 5. In this embodiment, the elastic member 5 and the cylinder 3 are cooperatively connected to form a first vibration reduction structure, which effectively utilizes the vibration reduction property of the elastic member and the buffering property of the gas in the cylinder 3 to buffer the radial vibration generated by the compressor body 2, thereby achieving a first vibration reduction effect.
[0028] The elastic member 5 includes a plurality of springs, which are evenly spaced apart along the axial direction of the compressor body 2, and can form a more balanced radial vibration reduction effect on the compressor body 2, thereby preventing uneven force from affecting the vibration reduction effect.
[0029] In other embodiments, the elastic member 5 may also be a rubber elastomer such as vibration-damping rubber or elastic sponge, and a rigid member may be arranged inside the elastic member 5, so as to cooperate with the rigid member 5 to improve the rigidity of the elastic member 5 and ensure that the cylinder 3 and the piston 4 can reciprocate in the same straight line.
[0030] The two ends of the spring are connected to the compressor body 2 and the piston 4 respectively, and are further connected to the cylinder 3 through the piston 4 to form a first vibration reduction structure. The end of the spring close to the compressor body 2 is fixed to the outer surface of the compressor body 2 by welding, and then the other end is also fixedly connected to the fixing plate of the piston 4 by welding. The welding method ensures the stability of the spring while providing sufficient elastic space for the spring movement, and can also prevent the compressor body 2 from vibrating too much to cause the spring to deviate and damage the piston and cylinder, and can also reduce the radial vibration of the compressor body 2 to the greatest extent.
[0031] In one embodiment, a cylinder seat is provided on the chassis 1, and an annular fixing groove is provided on the cylinder seat. The cylinder is fixedly arranged in the corresponding annular fixing groove on the chassis 1 by welding. The piston 4 and the cylinder 3 cooperate to make a linear reciprocating motion, and the coaxiality requirement of the piston 4 and the cylinder 3 can be fully guaranteed by fixing the cylinder 3 by welding.
[0032] The second vibration reduction structure includes a foot pad 6, and the compressor body 2 includes a support leg 7, which is mounted on the foot pad 6 and supported by the foot pad 6. A fixing groove is provided on the chassis 1, and the foot pad 6 is fixedly mounted in the fixing groove and connected to the support leg 7 to form an elastic support for the compressor body 2. When the compressor body 2 vibrates, the second vibration reduction structure uses the soft characteristics of the foot pad 6 to buffer the axial vibration generated by the compressor body 2, thereby achieving a second vibration reduction effect.
[0033] In one embodiment, an airbag 8 is provided in the foot pad 6. In this embodiment, the airbag 8 is built into the vibration-damping foot pad 6, and a cavity for accommodating the airbag 8 is opened at the center of the foot pad 6. The airbag 8 and the foot pad 6 are used together to form a second vibration-damping structure. The upper end of the foot pad 6 is mounted on the corresponding holes of the four legs 7 of the bottom flange of the compressor body 2, and the lower end is fixedly mounted in the corresponding fixing groove of the chassis 1. The foot pad 6 and the airbag 8 are used together to reduce the axial vibration of the compressor body 2 to the greatest extent, further avoiding the use of through bolts to fix the foot pad 6, and greatly improving the vibration-damping ability of the foot pad 6.
[0034] In one embodiment, an airbag 8 is disposed in the foot pad 6, and the air cavity 9 of the cylinder 3 is connected to the airbag 8. Specifically, in this embodiment, the air cavity 9 is connected to the airbag 8 through a hose 10. A communication channel is disposed on the chassis 1, and the hose 10 is disposed in the communication channel.
[0035] In this embodiment, a docking hole is provided at the lower end of the cylinder 3 for docking with the upper hole of the hose 10, and a hole groove is provided on the outer surface of the airbag 8 for docking with the lower hole of the hose 10. The upper end of the hose 10 is connected to the built-in airbag 8 of the foot pad 6 at the lower end of the cylinder 3, thereby forming a third vibration reduction structure. The hose 10 is built into the communication channel provided inside the chassis 1, which can not only protect and limit the hose 10 through the communication channel, ensuring that the gas in the hose 10 does not bend when passing through, but also ensure the rational arrangement of the vibration reduction structure.
[0036] By arranging a hose 10 in the chassis 1, the air cavity 9 of the first vibration reduction structure is connected to the air bag 8 of the second vibration reduction structure to form a third vibration reduction structure. When the compressor works under unstable operating conditions, the spring is used to reduce vibration while pushing the piston 4 connected to the end of the spring to compress the gas in the cylinder 3. The gas enters the built-in air bag cavity of the foot pad 6 through the hose 10 in the chassis 1, thereby increasing the rigidity of the foot pad 6 and reducing the vibration and shaking of the compressor, thereby achieving a third vibration reduction effect. When the compressor body 2 works in an unstable condition of transportation or during operation on uneven roads, the compressor vibration reduction assembly can meet the vibration reduction requirements and ensure the smooth operation of the compressor.
[0037] In one embodiment, the hose 10 is in communication with the airbag 8 along the radial direction of the foot pad 6 .
[0038] In one embodiment, the hose 10 is axially connected to the airbag 8 from the bottom of the foot pad 6 , so there is no need to open holes or grooves on the foot pad 6 , which can ensure the structural integrity of the foot pad 6 as much as possible and improve the vibration reduction performance of the foot pad 6 .
[0039] The piston 4 is provided with a vent plug 11. A groove is provided on the upper outer surface of the cylinder 3 for use in conjunction with the vent plug 11. When the compressor body 2 is not in operation, the vent plug 11 can be pulled out to discharge the gas in the airbag 8, reduce the pressure, and increase the service life of the airbag 8.
[0040] From the perspective of vibration absorption and vibration reduction, the cylinder 3 and the chassis 1 can be made of cast iron. Considering the lower sealing performance, the piston 4, the foot pad 6, and the airbag 8 can be made of fabric composite materials, the hose 10 can be made of plastic, and the spring can be made of spring steel.
[0041] The number of the second vibration damping structures is the same as the number of the first vibration damping structures.
[0042] In a cross section perpendicular to the central axis of the compressor body 2, the foot pad 6 and the cylinder 3 are arranged in one-to-one correspondence, and the corresponding projection of the center line of the foot pad 6 and the projection of the central axis of the compressor body 2 are located on the center line of the cylinder 3, so that the foot pad 6 and the cylinder 3 can be used in pairs, and it is more convenient to form a first vibration reduction structure, a second vibration reduction structure and a third vibration reduction structure that cooperate with each other, thereby improving the force balance of the compressor body 2 and improving the vibration reduction performance of the compressor body 2.
[0043] The compressor assembly of this embodiment, the first vibration reduction structure and the second vibration reduction structure can effectively reduce the vibration of the compressor under operating conditions, the spring and the cylinder 3 cooperate to effectively reduce the radial vibration of the compressor body 2, and the foot pad 6 and the air bag 8 cooperate to effectively reduce the axial vibration of the compressor body 2; the built-in hose 10 of the chassis 1 connects the first vibration reduction structure and the second vibration reduction structure to form a third vibration reduction structure, making full use of energy conversion, and compressing the compressor vibration energy through the piston 4. The gas enters the air bag cavity of the foot pad 6, improves the rigidity of the foot pad 6, and feeds back to the connected compressor body 2, thereby reducing vibration. The design of the combination of the three vibration reduction structures uses the vibration of the compressor body 2 itself to generate kinetic energy to reduce vibration, fully reducing the vibration of the compressor body 2 and greatly improving the smooth operation of the compressor body 2.

The above are only preferred implementations of the present application.
