[0002] Air conditioning systems are an indispensable part of modern life, widely used in homes, businesses, industrial environments, and automobiles to provide comfortable temperature control. As the heart of the air conditioning system, the compressor is responsible for compressing low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure gas, thus achieving a cooling or heating cycle. The valves inside the compressor periodically impact the lift limit switch, easily causing vibration in the limit switch itself. This vibration is then transmitted to other parts of the compressor through mechanical conduction, ultimately radiating out as noise. Utility Model Content

[0003] The main purpose of this invention is to provide an exhaust valve, bearing assembly, compressor, and air conditioner, with the aim of reducing compressor noise.

[0004] To achieve the above objectives, this utility model provides an exhaust valve, which includes:

[0008] In one embodiment, the reinforcing member and the limiting body cooperate to form a reinforcing cavity.

[0009] In one embodiment, the middle portion of the reinforcing member protrudes in an arc shape away from the exhaust valve plate.

[0034] When an air conditioner is running, the compressor operates periodically to meet cooling or heating needs. The exhaust valve plate in the compressor pump body periodically impacts the lift limit switch, causing the lift limit switch to vibrate and generate noise. At the same time, the vibration generated by the impact can be transmitted to the bearing through the rivets, causing the bearing to vibrate. The vibration is transmitted to the compressor main housing to generate radiated noise, thereby increasing the compressor noise level.

[0035] In view of this, the present invention provides an exhaust valve, a bearing assembly, a compressor, and an air conditioner. A reinforcing member is provided on the limiting body, which increases the rigidity of the limiting body. When impacted by the exhaust valve plate, the vibration of the limiting body itself is reduced, and the noise generated by the vibration is consequently decreased. Simultaneously, the vibration response transmitted from the limiting body to other components such as the bearing through mechanical conduction is also reduced, further decreasing the radiated noise caused by vibration.

[0036] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0037] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes an exhaust valve, the exhaust valve comprising:

[0038] A valve seat 100 is provided with an exhaust port 110. When the exhaust valve is applied to a bearing assembly of a compressor, at least a portion of the bearing is configured as the valve seat 100, and the exhaust port 110 extends through at least a portion of the bearing in the axial direction of the bearing;

[0039] An exhaust valve plate 200 is provided, one end of which is connected to the valve seat 100, and the other end of which corresponds to the exhaust port 110 and can open or close the exhaust port 110. It is understood that the exhaust valve plate 200 has a first mounting section 210 and a deformation section 220, which are integrally formed. The deformation section 220 corresponds to the exhaust port 110 and can open or close the exhaust port 110. Specifically, the first mounting section 210 and the valve seat 100 are fixed together, thus achieving a fixed connection between the exhaust valve plate 200 and the valve seat 100. The deformation section 220 is used to open or close the exhaust port 110 and is elastic, capable of deforming under the influence of gas. In other words, when the pressure on the side of the exhaust port 110 facing away from the exhaust valve plate 200 is less than the elastic force of the deformation section 220, the deformation section 220 covers the exhaust port 110, thereby closing the exhaust port 110. When the pressure on the side of the exhaust port 110 facing away from the exhaust valve plate 200 is greater than the elastic force of the deformation section 220, the gas drives the deformation section 220 to bend and deform facing away from the exhaust port 110, separating the deformation section 220 from the exhaust port 110, thereby opening the exhaust port 110 and allowing the gas to be discharged; and

[0040] A limiter 300 is provided on the side of the exhaust valve plate 200 facing away from the exhaust port 110. The limiter 300 includes a limiting body 310 and a reinforcing member 320 on the surface of the limiting body 310 facing away from the exhaust valve plate 200. Specifically, the limiter 300 includes a limiting body 310 and a reinforcing member 320. The limiting body 310 can be a commonly used lift limiter 300, used to limit the movement stroke of the exhaust valve plate 200 and reduce the risk of damage due to excessive bending of the exhaust valve plate 200. That is, when the exhaust valve plate 200 opens the exhaust port 110 under pressure, it will impact the limiting body 310. After being impacted by the exhaust valve plate 200, the limiting body 310 is prone to vibration. Therefore, in this embodiment, a reinforcing member 320 is provided. The reinforcing member 320 is provided on the surface of the limiting body 310 facing away from the exhaust valve plate 200 and will not interfere with the exhaust valve plate 200. By adding reinforcing ribs, the rigidity of the limiting body 310 is increased, reducing the vibration amplitude when impacted by the exhaust valve plate 200, thus decreasing the noise generated by vibration. Simultaneously, the vibration response transmitted from the limiting body 310 to other components such as bearings via mechanical conduction is also reduced, further decreasing radiated noise caused by vibration. In one embodiment, the reinforcing member 320 can be a protruding rib disposed on the surface of the limiting body 310 facing away from the exhaust valve plate 200, with the rib and the limiting body 310 integrally formed, thus simplifying the manufacturing process. Optionally, multiple protruding ribs can be provided, spaced apart or intersecting each other, further enhancing the rigidity of the limiting body 310. Of course, in other embodiments, the reinforcing rib can also be an arch beam.

[0041] In this embodiment, the limiting body 310 restricts the movement stroke of the exhaust valve plate 200, reducing the risk of damage due to excessive bending. Furthermore, the reinforcing member 320 on the limiting body 310 increases its rigidity, reducing its own vibration when impacted by the exhaust valve plate 200, thus decreasing the noise generated by vibration. Simultaneously, the vibration response transmitted from the limiting body 310 to other components such as bearings via mechanical conduction is also reduced, further decreasing radiated noise caused by vibration. It is understood that in this embodiment, by increasing the rigidity of the limiting body 310 to reduce its vibration amplitude when impacted by the exhaust valve plate 200, noise generation and propagation are effectively reduced, providing users with a quieter and more comfortable operating environment.

[0042] In one embodiment of this utility model, reference is made to Figures 2 to 4The reinforcing member 320 and the limiting body 310 cooperate to form a reinforcing cavity 330. Specifically, the reinforcing member 320 and the limiting body 310 cooperate to form a reinforcing cavity 330, which can significantly improve the overall rigidity of the limiting body 310, and better resist deformation when impacted by the exhaust valve plate 200, thereby reducing vibration and noise. Moreover, the reinforcing cavity 330 can disperse the stress generated when the exhaust valve plate 200 impacts, reduce fatigue damage to the limiting body 310, and extend its service life. In addition, the reinforcing cavity 330 can change the propagation path of vibration waves, effectively absorb and attenuate the vibration energy generated by the impact of the exhaust valve plate 200, and reduce noise radiation. Optionally, the reinforcing cavity 330 can be rectangular, triangular, or irregular in shape, and is not limited here.

[0043] In one embodiment of this utility model, the middle portion of the reinforcing member 320 protrudes in an arc shape away from the exhaust valve plate 200. Specifically, the arc shape of the middle portion of the reinforcing member 320, which protrudes away from the exhaust valve plate 200, can better disperse and absorb the impact force from the exhaust valve plate 200. When the exhaust valve plate 200 impacts the limiting body 310, the impact force can be more evenly distributed on the reinforcing member 320, which can reduce the occurrence of local high-stress areas caused by the concentration of impact force, thereby reducing the occurrence of micro-deformation and thus reducing the vibration amplitude. In addition, when vibration is generated in the limiting body 310 and propagates outward, the arc-shaped structure can effectively disrupt the straight-line propagation of sound waves, thereby dispersing the sound energy and weakening the noise intensity.

[0044] In one embodiment of this utility model, the width of the middle portion of the reinforcing member 320 is smaller than the width of its end portion. The end portion of the reinforcing member 320 needs to be connected and fixed to the limiting body 310. The smaller width of the middle portion of the reinforcing member 320 compared to its end portion increases the contact area between the reinforcing member 320 and the limiting body 310, resulting in better connection reliability. This provides better support for the limiting body 310, enhances its rigidity, and also saves material usage, reducing the overall weight.

[0045] In one embodiment of this utility model, reference is made to Figure 2 The reinforcing member 320 has a protruding portion 321 on its surface facing away from the limiting body 310. The protruding portion 321 increases the structural strength of the reinforcing member 320, thereby improving its support and reinforcement effect on the limiting body 310. The protruding portion 321 can be located at the end of the reinforcing member 320, in the middle of the reinforcing member 320, or both at the end and in the middle; no limitation is made here. Optionally, the protruding portion 321 and the reinforcing member 320 are integrally formed.

[0046] In one embodiment of this utility model, the reinforcing member 320 and the limiting body 310 are integrally formed. This reduces the number of parts and assembly steps, lowering production costs and labor intensity. Furthermore, the seamless connection between the reinforcing member 320 and the limiting body 310 optimizes the vibration transmission path, effectively reducing noise generated by the interaction between components, and further reducing the overall noise of the compressor.

[0047] In one embodiment of this utility model, reference is made to Figure 1 The exhaust valve plate 200 includes a first mounting section 210 and a deformable section 220 connected to the first mounting section 210. The first mounting section 210 is connected to the valve seat 100, and the deformable section 220 is bent toward the exhaust port 110. This provides a force that presses against the exhaust port 110, thereby providing a better sealing effect when the exhaust port 110 is closed. In other words, the deformable section 220 has a tendency to move toward the exhaust port 110, allowing it to tightly cover the exhaust port 110, thus improving the sealing performance of the deformable section 220 when the exhaust port 110 is closed.

[0048] And / or, the exhaust valve further includes a limiting valve plate, which is disposed between the exhaust valve plate 200 and the limiter 300. The limiting valve plate separates the exhaust valve plate 200 from the limiter 300. When the exhaust valve plate 200 opens under pressure, it first contacts the limiting valve plate. Because the limiting valve plate has a certain rigidity, it provides a buffering effect on the exhaust valve plate 200, reducing the speed at which the exhaust valve plate 200 impacts the limiter 300, thereby reducing the vibration and noise generated by the impact on the limiter 300, and consequently reducing the vibration and noise of the compressor. In other words, the movement stroke of the deformation section 220 of the exhaust valve plate 200 can be divided into two parts: the deformation section 220 of the exhaust valve plate 200 is in contact with the limiting valve plate, and then the deformation section 220 of the exhaust valve plate 200 disengages from the limiting valve plate. It is understood that the limit valve plate includes a third mounting section and an abutment section. The third mounting section is fixed on the valve seat 100, and the end of the abutment section away from the third mounting section is used to abut against the deformation section 220, and then moves toward the limit body 310.

[0049] In one embodiment of this utility model, reference is made to Figures 2 to 4The limiting body 310 includes a second mounting section 311 and a limiting section 312 connected to the second mounting section 311. The second mounting section 311 is connected to the valve seat 100, and the limiting section 312 is bent away from the exhaust port 110. It is understood that the second mounting section 311 is connected to the valve seat 100, and the end of the deformable section 220 away from the first mounting section 210 and the end of the limiting section 312 away from the second mounting section 311 are spaced apart. This provides movement space for the exhaust valve plate 200, preventing the limiting section 312 and the deformable section 220 from directly contacting each other and causing the exhaust valve plate 200 to fail to open.

[0050] Wherein, the reinforcing member 320 is at least connected to the limiting segment 312. It can be understood that the end of the reinforcing member 320 is fixedly connected to the limiting segment 312, which can enhance the structural strength of the limiting segment 312; and / or, the reinforcing member 320 is connected to the end of the limiting segment 312 away from the second mounting segment 311, that is, the end of the reinforcing member 320 is connected to the limiting segment 312 and the second mounting segment 311. It can be understood that the limiting segment 312 and the second mounting segment 311 are respectively connected to one end of the reinforcing member 320.
