[0002] With the development of science and technology, the progress of society, and the continuous maturity of artificial intelligence technology, people's pursuit of quality of life is increasing.

[0003] People initially thought of air conditioners as appliances that could cool or heat, lower or increase indoor temperature, and that were sufficient to meet daily needs. However, as people's quality of life continues to improve, their requirements for air conditioners have become more stringent. Cooling or heating capabilities are no longer the only requirement, but the requirements for living comfort have also increased, namely, low noise.

[0004] The noise sources of the air conditioner can be roughly divided into the fan noise in the hanging machine and the compressor noise. The fan noise can generally be optimized by reducing the fan speed and adjusting the fan size. However, the countermeasures for improving the compressor noise are relatively limited because the compressor noise sources are more, such as motor sound, beat frequency sound, valve sound and blade chasing sound, etc.

[0005] In the prior art, the valve plate of the compressor is riveted together with the support by rivets, and the valve plate covers the exhaust port of the support to achieve a sealing effect. However, when the compressor is running, a valve plate slapping sound will be heard during the opening and closing process of the valve plate. This slapping sound is the main source of noise for the compressor, which reduces the user experience. Utility Model Content

[0034] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0036] For example, a support assembly for reducing compressor noise includes a seat body, the seat body includes a sleeve and a panel integrally formed in the circumferential direction of one end of the sleeve, the panel is provided with an exhaust port facing an end face of the sleeve; a valve plate, the valve plate includes a fixed portion and a shielding portion connected to each other, the fixed portion is connected to the panel, and the shielding portion shields the exhaust port; an elastic member, the elastic member is arranged between the panel and the valve plate, and the elastic member is relative to the fixed portion and the shielding portion; wherein the exhaust volume of the exhaust port changes so that the shielding portion moves up and down based on the fixed portion, and the shielding portion moves downward to compress the elastic member.

[0037] The present embodiment provides a support assembly and a compressor for reducing compressor noise. An elastic member is arranged between a panel and a valve plate. When the valve plate moves downward, that is, when it closes with the exhaust port, the elastic member can produce a buffering effect on the valve plate, thereby increasing the damping during the valve plate slapping process and effectively reducing the slapping force of the valve plate, thereby achieving the purpose of reducing the valve plate slapping sound. During the operation of the compressor, a better noise reduction effect is achieved, thereby improving the user experience.

[0038] Embodiment 1:

[0039] refer to Figure 1-Figure 3 This example provides a support assembly for reducing compressor noise, including a seat body 1, a valve plate 2 and an elastic member 3.

[0040] Among them, the seat body 1 can be the upper support or the lower support in the compressor, which is not limited here. The seat body 1 includes a sleeve 11 and a panel 12 integrally formed in the outer circumferential direction of one end of the sleeve 11. The panel 12 is provided with an exhaust port 13 on one end face facing the sleeve 11. The exhaust port 13 is used to leak the pressure generated by the compressed refrigerant during the operation of the compressor.

[0041] The valve plate 2 includes a fixed portion 21 and a shielding portion 22 that are connected to each other. The fixed portion 21 is connected to the panel 12 and is used to establish a connection relationship between the valve plate 2 and the panel 12, so that the valve plate 2 is installed on the panel 12. The shielding portion 22 is used to shield the exhaust port 13. Combined with conventional technology, the compressor includes a rotor, a stator, a shaft and a cylinder body. When the compressor is powered on, a magnetic field will be generated between the rotor and the stator, causing the rotor to rotate. Since the shaft is fixed by being heat-fitted to the inner diameter of the rotor, the rotor will drive the shaft to rotate, so that the shaft rotates to compress the refrigerant in the cylinder body. When the compressed refrigerant meets a certain pressure, it will squeeze the valve plate 2 open and leak through the exhaust port 13 on the panel 12, and then flow into the system through the compressor outlet pipe for refrigeration.

[0042] Therefore, it can be known that when the compressed refrigerant meets a certain pressure, the valve plate 2 will be squeezed open. When the pressure generated by the refrigerant is not enough to squeeze the valve plate 2 open, the shielding portion 22 of the valve plate 2 will shield the exhaust port 13.

[0043] The elastic member 3 is arranged between the panel 12 and the valve plate 2, and the elastic member 3 is relative to between the fixing portion 21 and the shielding portion 22. Since the fixing portion 21 is used to connect the panel 12, and the shielding portion 22 is used to shield the exhaust port 13, the position of the elastic member 3 needs to avoid the fixing portion 21 and the shielding portion 22, that is, the position of the elastic member 3 relative to between the fixing portion 21 and the shielding portion 22, on the one hand, does not affect the connecting function of the fixing portion 21 and the shielding function of the shielding portion 22, and on the other hand, can also play a buffering role for the downward movement of the shielding portion 22.

[0044] Specifically, the change in the exhaust volume of the exhaust port 13 causes the shielding portion 22 to move up and down based on the fixed portion 21, and the shielding portion 22 moves downward to compress the elastic member 3. It can be seen from the above description that when the compressed refrigerant meets a certain pressure, the valve plate 2 will be squeezed open, that is, the exhaust volume is relatively large at this time, and the exhaust volume is sufficient to squeeze open the valve plate 2, so that the shielding portion 22 on the valve plate 2 moves upward based on the fixed portion 21. When the pressure generated by the refrigerant is not enough to squeeze open the valve plate 2, that is, the exhaust volume is relatively small at this time, and the exhaust volume is insufficient to squeeze open the valve plate, the shielding portion 22 on the valve plate 2 moves downward based on the fixed portion 21. Since the elastic member 3 is arranged between the valve plate 2 and the panel 12, during the downward movement of the blocking portion 22 on the valve plate 2, which is equivalent to the movement of the valve plate 2 toward the panel 12, the valve plate 2 compresses the elastic member 3, and the elastic member 3 has a buffering effect on the valve plate 2, thereby increasing the damping of the valve plate 2 during the impact process, and effectively reducing the impact force of the valve plate 2, thereby achieving the purpose of reducing the impact sound of the valve plate 2, so that during the operation of the compressor, it has a better noise reduction effect and improves the user experience.

[0045] Embodiment 2:

[0046] refer to Figure 4-Figure 6 In this example, a support assembly for reducing compressor noise is provided, which also includes a guard plate 4. The guard plate 4 is located above the valve plate 2. The shielding portion 22 moves upward to abut against the guard plate 4. The guard plate 4 protects the valve plate 2, making the valve plate 2 less likely to be damaged and increasing the service life of the valve plate 2.

[0047] The valve plate 2 is made of a material with elasticity and restorability, and has high impact fatigue strength and high tensile strength. When the valve plate 2 is subjected to the pressure generated by the compressed refrigerant, the shielding part 22 can move upward based on the fixed part 21 and deform. When the pressure of the refrigerant is not enough to squeeze open the shielding part 22, the shielding part 22 can move downward based on the fixed part 21, that is, restore to the initial state.

[0048] The provision of the guard plate 4 can limit the distance that the shielding portion 22 moves upward, preventing the shielding portion 22 from being overly deformed due to excessive pressure, thereby protecting the valve plate 2 and increasing the service life of the valve plate 2.

[0049] In some examples, one end of the guard plate 4 relative to the fixing portion 21 is locked to the panel 12 with the fixing portion 21 via a locking member, thereby ensuring the installation stability of the valve plate 2 and the guard plate 4 and improving the performance stability of the support assembly.

[0050] It can be understood that during the production process of the support assembly, the valve plate 2 and the protective plate 4 are installed manually or by automated equipment. After one end of the protective plate 4 relative to the fixed portion 21 is aligned with the fixed portion 21, the end of the protective plate 4 is locked together with the fixed portion 21 on the panel 12 using a locking member, such as by using rivets to press the valve plate 2 and the protective plate 4 to ensure the installation stability of the valve plate 2 and the protective plate 4.

[0051] The shape of the guard plate 4 matches the shape of the valve plate 2, ensuring the protective effect of the guard plate 4 on the valve plate 2, reducing the use of materials, and reducing production costs. Under normal conditions, the guard plate 4 can be tilted, that is, the end of the guard plate 4 relative to the fixed portion 21 is locked to the panel 12 with the fixed portion 21 through a locking member, and there is a gap between the end of the guard plate 4 relative to the shielding portion 22 and the shielding portion 22, and the gap is the distance value of the guard plate 4 to limit the upward movement of the valve plate 2.

[0052] In this example, the protective plate 4 is provided to protect the valve plate 2 , so that the valve plate 2 is not easily damaged, and the service life of the valve plate 2 is effectively increased.

[0053] Embodiment three:

[0054] refer to Figure 7In this example, a mounting groove 14 for mounting the valve plate 2 is provided on one end surface of the panel 12 facing the sleeve 11, and the exhaust port 13 is formed in the mounting groove 14. The mounting groove 14 is provided to limit the installation of the valve plate 2, thereby improving the installation stability of the valve plate 2 and further improving the performance stability of the support assembly.

[0055] It can be understood that the mounting groove 14 includes a groove bottom and an opening opposite to the groove bottom. The opening size of the mounting groove 14 is set to be larger than the size of the valve plate 2 to facilitate the positioning and assembly of the valve plate 2. In addition, the depth of the mounting groove 14 can also be set to be larger than the thickness of the valve plate 2, so that the valve plate 2 is completely located in the mounting groove 14, avoiding the valve plate 2 protruding outside the mounting groove 14, that is, avoiding the valve plate 2 protruding from the surface of the panel 12 and affecting the installation of other components or reducing the limiting effect on the valve plate 2.

[0056] In some examples, a positioning groove 15 for positioning the elastic member 3 is further formed at the bottom of the installation groove 14. The elastic member 3 is installed in the positioning groove 15 to ensure the installation stability of the elastic member 3, thereby improving the performance stability of the support assembly.

[0057] For example, the elastic member 3 is a spring, the positioning groove 15 is an annular positioning groove 15, and the shape of the positioning groove 15 matches the shape of the elastic member 3, so that the elastic member 3 is completely confined in the positioning groove 15, thereby improving the installation stability of the elastic member 3.

[0058] The shape of the shielding portion 22 matches the shape of the exhaust port 13 , and the area of ​​the shielding portion 22 is larger than the area of ​​the exhaust port 13 , thereby ensuring the shielding effect of the shielding portion 22 on the exhaust port 13 .

[0059] The panel 12 is provided with a through hole 16 for alignment installation on one end surface facing the sleeve 11, which improves the installation accuracy and assembly convenience of the support assembly. In combination with conventional technology, the seat body 1 is usually connected to a silencer cover, which is used to silence and reduce the noise generated when the compressor is running. When assembling the panel 12 with the silencer cover, the through hole 16 on the panel 12 and the positioning hole provided on the silencer cover can be used for alignment assembly, thereby improving the assembly efficiency of the support assembly.

[0060] Embodiment 4:

[0061] The present application also provides a compressor, including a support assembly in any of the above embodiments, the support assembly includes a seat body 1, the seat body 1 includes a sleeve 11 and a panel 12 integrally formed in the circumferential direction of one end of the sleeve 11, the panel 12 is provided with an exhaust port 13 on one end face facing the sleeve 11; a valve plate 2, the valve plate 2 includes a fixed portion 21 and a shielding portion 22 connected to each other, the fixed portion 21 is connected to the panel 12, and the shielding portion 22 shields the exhaust port 13; an elastic member 3, the elastic member 3 is arranged between the panel 12 and the valve plate 2, and the elastic member 3 is relative to the fixed portion 21 and the shielding portion 22; wherein, the exhaust volume of the exhaust port 13 changes so that the shielding portion 22 moves up and down based on the fixed portion 21, and the shielding portion 22 moves downward to compress the elastic member 3.

[0062] By adopting the support assembly, an elastic member 3 is arranged between the panel 12 and the valve plate 2. The elastic member 3 is utilized to effectively reduce the slapping force of the valve plate 2, thereby achieving the purpose of reducing the slapping sound of the valve plate 2. During the operation of the compressor, a better noise reduction effect is achieved, thereby improving the user experience.

[0063] To sum up, the utility model provides a support assembly and a compressor for reducing compressor noise. An elastic member is arranged between the panel and the valve plate. When the valve plate moves downward, that is, when it closes with the exhaust port, the elastic member can produce a buffering effect on the valve plate, thereby increasing the damping of the valve plate during the slapping process and effectively reducing the slapping force of the valve plate, thereby achieving the purpose of reducing the slapping sound of the valve plate, so that during the operation of the compressor, a better noise reduction effect is achieved, thereby improving the user experience.
