The compressor assembly, air conditioner, and control method and control device of the air conditioner of the present invention are given below with reference to the drawings.

[0039] As Figure 1 and Figure 2As shown, the compressor assembly of the air conditioner according to the embodiment of the first aspect of the present invention includes a compressor 1 and a dynamic vibration absorber.

[0040] The compressor 1 has a housing 11; the dynamic vibration absorber is installed outside the housing 11 of the compressor 1. The dynamic vibration absorber includes a plurality of vibration absorbers 2, and the plurality of vibration absorbers 2 are all installed on the housing 11 of the compressor 1 through a clamping mechanism 3, and the plurality of vibration absorbers 2 are spaced along the housing 11 of the compressor 1.

[0041] It should be noted that the dynamic vibration absorber is not a simple integrated design, but is composed of a plurality of independent vibration absorbers 2, and these vibration absorbers 2 are fixed on the housing 11 of the compressor 1 through a carefully designed clamping mechanism 3. This distributed layout strategy takes into account space limitations and the efficiency of vibration control.

[0042] Among them, each vibration absorber 2 is a small shock-absorbing unit with its own frequency modulation ability, and constitutes an elastic mass system by basic components such as springs and mass blocks. They can respond to vibrations of specific frequencies and generate vibrations of opposite phases to cancel out the vibrations of the compressor 1. In addition, the clamping mechanism 3 is responsible for fixing the installation of the vibration absorber 2 on the housing 11 of the compressor 1, so that the vibration absorbers 2 can be spaced along the circumference of the housing 11. This layout is beneficial to absorbing vibrations in all directions.

[0043] Furthermore, it can be understood that the working principle of the compressor assembly of the present invention is as follows: The dynamic vibration absorber works based on the principle of the dynamic vibration absorber 2, that is, by adjusting the natural frequency of the vibration absorber 2 itself to match the vibration frequency of the compressor 1, the absorption and conversion of vibration energy are achieved. When the compressor 1 operates and generates vibrations, these vibrations will be transmitted to each vibration absorber 2.

[0044] In the related art, during the operation of the variable-frequency compressor 1, mechanical vibrations of different frequency bands will be generated, which will lead to: (1) When the rotational speed of the compressor 1 increases, the double-frequency sound caused by the vibration of the compressor 1 becomes larger, becoming the main component of the noise source of the compressor 1, directly causing the noise radiated by the outdoor unit to become larger and affecting the user experience; (2) The pipeline system is the main transmission path of the vibration of the compressor 1. The vibration magnitude of the compressor 1 directly affects the amplitude and stress of the pipeline, and the problem of excessive amplitude and stress of important pipelines has always been the focus of attention in the air-conditioning industry.

[0045] To solve the above-mentioned vibration problem of the air-conditioning system, the following solutions are usually adopted: (1) Add foot pads at the bottom of the compressor to isolate vibration and reduce the vibration transmission from the compressor to the air-conditioning shell, but the vibration reduction and noise reduction effects are limited; (2) Wrap the compressor 1 with sound-absorbing cotton for passive noise reduction. Its disadvantage is that the noise reduction degree is only determined by the sound absorption coefficient of the sound-absorbing cotton, and the sound-absorbing cotton has different sound absorption coefficients for noises in different frequency bands, and the sound-absorbing cotton has no effect on the noises in some frequency bands; (3) Rectify the pipelines with excessive amplitude and stress. The rectification methods include adding rubber blocks, modifying pipes, and adding fixings, etc., which will waste a lot of rectification time and increase costs.

[0046] Therefore, to solve the technical defects existing in the above-mentioned related technologies and solve the vibration problem of the air-conditioning system, starting from reducing the vibration of the compressor 1, the present invention designs a dynamic vibration absorber 2 that can be installed on the air-conditioning compressor 1, and uses the principle that the vibration absorber 2 generates a reaction force on the controlled structure during its own resonance to suppress the vibration of the compressor 1.

[0047] Furthermore, the compressor assembly of the present invention has at least the following advantages compared with the related technologies.

[0048] (1) Precise frequency modulation and vibration reduction: Through the discrete dynamic vibration absorber device installed on the outer side of the compressor 1 housing 11, which is composed of multiple small vibration absorbers 2, it can dynamically adjust its own natural frequency according to the actual vibration frequency during the operation of the compressor 1, realizing precise frequency modulation and vibration reduction. This precise adjustment improves the vibration reduction effect, especially for the multi-frequency vibration of the variable-frequency compressor 1 at different speeds, with excellent adaptability.

[0049] (2) Space optimization: Considering the problem of limited space around the air-conditioning compressor 1 in the design, small vibration absorbers 2 are adopted and a discrete distributed layout is used, which not only makes full use of the limited space but also ensures the maximization of the vibration reduction effect, avoiding the problem of sacrificing the vibration reduction performance due to space limitations.

[0050] (3) Active intelligent control: Use an acceleration sensor to monitor the vibration signal, and through the control system for fast Fourier transform (FFT) analysis, dynamically calculate the adjustment direction and distance of the mass block of the vibration absorber 2, and then drive by the motor 23 to achieve automatic adjustment. The whole process is automated and responds quickly, which is more active and precise than the traditional static vibration reduction measures.

[0051] (4) Cost-effectiveness: Compared with traditional methods such as rectifying pipelines, installing foot pads or using sound-absorbing cotton, the solution of the present invention does not require expensive rectification costs, nor does it rely on time-consuming physical transformations. In the long run, it can significantly reduce the maintenance cost, reduce the failures and repair frequencies caused by vibration, and improve the overall service life of the equipment.

[0052] (5) Improved user experience: By effectively suppressing the vibration of compressor 1, especially reducing the frequency noise caused by the increase in speed, the user experience is greatly improved, the noise pollution of the outdoor unit is reduced, and the demand for low-noise quality of life in modern living environments is met.

[0053] (6) Wide scope of application: The design of the dynamic vibration absorption device is not limited to a specific type of compressor 1 or air conditioner model. In theory, it is applicable to a variety of compressor 1 applications and has good versatility and promotion value.

[0054] like Figure 2 As shown, according to some embodiments of the present invention, the vibration absorber 2 includes a concentrated mass block 21 , a driving member and a guide rail 22 . The concentrated mass block 21 is transmission-connected to the driving member, and the concentrated mass block 21 is slidably mounted on the guide rail 22 .

[0055] In this embodiment, the concentrated mass block 21 plays the role of "mass". In the theory of dynamic vibration absorption, the vibration of the mass block interacts with the vibration of the main system, and the system vibration is absorbed and reduced by adjusting its movement. The mass of the concentrated mass block 21 is carefully calculated to ensure that it can match the vibration frequency of the compressor 1 at a specific frequency, so as to maximize the vibration reduction performance.

[0056] The driving member connected to the concentrated mass block 21 usually involves an electric motor or other power conversion device, such as a screw 24 or a gear system driven by a motor 23. The function of this driving member is to accurately control the position of the concentrated mass block 21 according to the instructions issued by the control system, thereby adjusting the natural frequency of the vibration absorber 2. The dynamic response capability of the driving member is the key to the real-time adjustment of the entire system.

[0057] In addition, the concentrated mass block 21 is mounted on the guide rail 22 and can slide along the guide rail 22. The linear guide design of the guide rail 22 ensures that the mass block moves smoothly up and down or left and right, providing stable physical support for precise frequency adjustment. This design allows the mass block to respond quickly to the drive of the driver while maintaining stability to achieve frequency adjustment.

[0058] Further, based on the specific structure of the above-mentioned vibration absorber 2, the working principle of the dynamic vibration absorption device of the present invention is briefly described as follows: The vibration signal of the compressor 1 is detected by a sensor, and the signal is sent to the control system for analysis to determine the main frequency of the current vibration. According to the analysis result, the control system calculates the position to which the concentrated mass block 21 should be adjusted to achieve the natural frequency matching the main frequency. The driving member (such as the motor 23) then acts, and through the transmission mechanism, it pushes or pulls the concentrated mass block 21 to slide along the guide rail 22 until the calculated position is reached. Once the position of the concentrated mass block 21 is accurately adjusted and the natural frequency of the vibration absorber 2 is consistent with the vibration frequency of the compressor 1, the vibration absorber 2 begins to exert its maximum efficiency, generating vibrations with a phase opposite to the main vibration, thereby significantly reducing the vibration of the compressor 1 and the resulting noise.

[0059] As Figure 2 shown, in some embodiments of the present invention, the driving member is the motor 23. The driving section of the motor 23 is connected to the screw 24, and the nut seat 25 is rotatably sleeved on the screw 24. The concentrated mass block 21 is fixedly connected to the nut seat 25.

[0060] It can be understood that this embodiment gives the structural scheme driven by the motor 23. In this embodiment, the motor 23 is used as the driving member, and its output shaft is directly connected to the screw 24, while the nut seat 25 can rotate freely around the screw 24. The concentrated mass block 21 is fixed together with the nut seat 25, which means that when the motor 23 starts and rotates the screw 24, the nut seat 25 together with the concentrated mass block 21 thereon will move up and down along the screw 24.

[0061] The working principle in this embodiment is as follows: The control system controls the rotation direction and number of turns of the screw 24 through the motor 23 according to the monitored vibration signal, and then adjusts the positions of the nut seat 25 and the concentrated mass block 21 on the guide rail 22, thereby changing the natural frequency of the vibration absorber 2 to match the vibration frequency of the compressor 1 and achieving efficient vibration absorption and noise reduction.

[0062] In this way, the motor 23 driving scheme can provide precise positioning control, is easy to realize automatic adjustment, is suitable for scenarios that require fine frequency adjustment, has a fast response speed, and can adapt to the frequency change of the compressor 1 in real time.

[0063] In some other embodiments of the present invention, the driving member is a cylinder, and the driving section of the cylinder is fixedly connected to the concentrated mass block 21 through a linear connecting member.

[0064] It can be understood that this embodiment gives the structural scheme driven by the cylinder. In this embodiment, the driving member uses a cylinder, and the cylinder is directly connected to the concentrated mass block 21 through a linear connecting member. The telescopic movement of the piston of the cylinder directly pushes or pulls the concentrated mass block 21 to move linearly along the guide rail 22.

[0065] The working principle in this embodiment is as follows: The control system controls the air intake and exhaust of the cylinder according to the vibration signal, thereby driving the linear connecting piece to move the concentrated mass 21, achieving the purpose of adjusting the natural frequency. This method also changes the natural frequency of the vibration absorber 2 to match the vibration frequency of the compressor 1, reducing vibration.

[0066] In this way, the cylinder drive scheme is simple and reliable, suitable for applications that require rapid large-stroke adjustment, with a direct response and the ability to withstand large forces, suitable for handling higher vibration energy scenarios.

[0067] As Figure 1 and Figure 2 shown, according to some embodiments of the present invention, the clamping device includes a clamping base 31 and a plurality of clamping arms 32. The clamping base 31 is fixed and surrounds the outside of the housing 11 of the compressor 1. The plurality of clamping arms 32 are evenly distributed on the clamping base 31 along the circumferential direction of the housing 11, and each clamping arm 32 is fixed with a vibration absorber 2.

[0068] In this way, the clamping base 31 surrounds but does not interfere with the normal operation of the compressor 1, ensuring a stable support for the housing 11 of the compressor 1. At the same time, it provides a reliable installation platform for the vibration absorber 2 without occupying extra space, suitable for the design of a compact air-conditioning system. At the same time, the layout of the clamping arms 32 ensures that the vibration absorber 2 can cover vibrations in various directions that the compressor 1 may generate. The evenly distributed design means that vibrations in any direction of the compressor 1 can be sensed in a timely manner and responded to by the nearby vibration absorber 2, thereby achieving an all-directional vibration reduction effect.

[0069] According to some embodiments of the present invention, an acceleration sensor is installed on the compressor 1, and the control device of the air conditioner is respectively connected to the acceleration sensor and the driving member.

[0070] The control device is used to receive the vibration signal of the compressor 1 detected by the acceleration sensor, and control and adjust the working state of the driving member according to the vibration signal of the compressor 1, so that the concentrated mass 21 is in the target position. At this time, the natural frequency of the dynamic vibration absorption device is equal to the main vibration frequency of the compressor 1.

[0071] In this way, through real-time monitoring and feedback control, the dynamic frequency modulation of the dynamic vibration absorber 2 is realized, ensuring the best vibration absorption effect under different working conditions. Compared with the traditional static vibration absorption scheme, this dynamic adjustment strategy can more effectively cope with the frequency changes caused by the speed change of the compressor 1, improving the vibration reduction efficiency and the stability of the system, and ultimately enhancing the user experience.

[0072] The air conditioner according to the second aspect embodiment of the present invention includes the compressor assembly of the air conditioner described in the first aspect embodiment of the present invention.

[0073] The control method and control device of the air conditioner proposed by the present invention will be described below with reference to the accompanying drawings. Among them, before the detailed description of the embodiments of the present invention, the entire application scenario will be described first. The control method, control device, electronic device, and computer-readable storage medium of the air conditioner in the embodiments of the present invention can be applied not only to the local air conditioner but also to the cloud platform in the Internet field, or the cloud platform in other types of Internet fields, or can also be applied to third-party devices. Among them, third-party devices may include various different types such as mobile phones, tablets, laptops, in-vehicle computers, and other intelligent terminals.

[0074] Below, only the control method applicable to the air conditioner will be used as an example for illustration. It should be understood that the control method in the embodiments of the present invention can also be applicable to the cloud platform and third-party devices.

[0075] As Figure 3 shown, the control method of the air conditioner based on the second aspect embodiment of the present invention according to the third aspect embodiment of the present invention includes: Step S1, obtain the vibration signal of the compressor 1 according to the acceleration sensor installed on the compressor 1; In step S1, the acceleration sensor is installed on the compressor 1. This is a highly sensitive monitoring device that can capture the vibration information from small to large amplitudes generated during the operation of the compressor 1. When the compressor 1 operates, the vibration generated by it will be transmitted to the sensor, and the sensor will then convert it into an electrical signal.

[0076] This step is the starting point of the whole process, ensuring the real-time performance and accuracy of the subsequent control strategy, because the vibration signal directly reflects the actual working state of the compressor 1 and is the premise for dynamically adjusting the vibration absorber 2.

[0077] Step S2, control and adjust the working state of the driving member in the vibration absorber 2 according to the vibration signal of the compressor 1, so that the concentrated mass block 21 in the vibration absorber 2 is in the target position, and at this time, the natural frequency of the dynamic vibration absorption device is equal to the main vibration frequency of the compressor 1.

[0078] In step S2, the control device quickly analyzes the vibration signal collected in step S1, mainly to identify the main vibration frequency of the compressor 1. Then, based on this frequency, calculate where the concentrated mass block 21 should be located to make the natural frequency of the vibration absorber 2 match it. After that, adjust the position of the concentrated mass block 21 through the driving member (such as the motor 23 or the cylinder), and accurately move it to the calculated target point.

[0079] This dynamic adjustment mechanism is the core innovation of the present invention. It can not only automatically adapt to the vibration frequency changes of the compressor 1 at different speeds, but also ensure the best vibration absorption effect. By adjusting the natural frequency of the vibration absorber 2 in real time to be consistent with the main vibration frequency of the compressor 1, efficient absorption and suppression of vibration are achieved, and the noise is reduced.

[0080] In summary, the above two steps constitute a closed-loop control system, achieving precise control of the vibration of the compressor 1. Through real-time monitoring, analysis, and dynamic adjustment, the vibration absorber 2 is always kept consistent with the vibration frequency of the compressor 1, achieving the optimal vibration reduction effect, solving the deficiencies of traditional vibration absorption technologies, and improving the performance of the air-conditioning system and user comfort.

[0081] According to some embodiments of the present invention, the step of controlling the working state of the driving member in the vibration absorber 2 according to the vibration signal of the compressor 1 specifically includes: Calculating the current main vibration frequency of the compressor 1 according to the vibration signal; Controlling and adjusting the working state of the driving member according to the comparison result between the current main vibration frequency and the previously recorded main vibration frequency of the compressor 1.

[0082] In this embodiment, the specific adjustment process of the vibration absorber 2 is as follows: First, the system receives the vibration signal of the compressor 1 transmitted by the acceleration sensor, and calculates the current main vibration frequency of the compressor 1 by analyzing these signals (for example, using the fast Fourier transform FFT algorithm). This frequency is the main fluctuation mode of the vibration of the compressor 1 and is also the key reference for vibration reduction.

[0083] Then, the currently calculated main vibration frequency of the compressor 1 is compared with the previously recorded main frequency. Here, the "previous record" can be understood as the previous moment, the previous cycle, or the average value within a set period, depending on the system design. The purpose of the comparison is to determine whether there is a change in the vibration state of the compressor 1, as well as the trend or amplitude of the change.

[0084] Based on the above comparison result, the control system makes a decision. If it is found that the main vibration frequency of the compressor 1 has a significant change or deviates from the ideal value, the working state of the driving member (such as the motor 23 or the cylinder) is adjusted. The adjustment may include changing the rotation direction, speed of the motor 23, or the expansion and contraction amount of the cylinder, so as to move the concentrated mass block 21 in the vibration absorber 2 to a new target position. This position adjustment ensures that the natural frequency of the vibration absorber 2 matches the current main vibration frequency of the compressor 1 again, achieving the best vibration absorption effect.

[0085] In this way, through the above steps, the control system of this embodiment not only responds to the vibration state of the compressor 1 in real time, but also enhances the pertinence of dynamic adjustment through the comparison of historical data, improves the vibration absorption efficiency and accuracy, and ensures that good vibration reduction and noise reduction performance can be maintained even when the operating conditions of the compressor 1 change.

[0086] In some embodiments of the present invention, the step of controlling and adjusting the working state of the driving member according to the comparison result between the current main vibration frequency and the previously recorded main vibration frequency of the compressor 1 specifically includes: In the case where the current main vibration frequency is not equal to the previously recorded main vibration frequency of the compressor 1, calculate the target position of the concentrated mass block 21 according to the current main vibration frequency, and control the driving member to start and move the concentrated mass block 21 to the target position.

[0087] Wherein, at the target position, the natural frequency of the dynamic vibration absorber is equal to the main vibration frequency of the compressor 1.

[0088] In this embodiment, if the current main vibration frequency is inconsistent with the previous record, it indicates that the vibration state of the compressor 1 has changed, and the vibration absorber 2 needs to be adjusted. In the case of confirming the need for adjustment, calculate the target position to which the concentrated mass block 21 should move according to the current main vibration frequency. The determination of this position is based on the principle that the natural frequency of the dynamic vibration absorber 2 matches the main vibration frequency of the compressor 1, and precise calculation is achieved through a mathematical model or algorithm.

[0089] The control device starts the driving member (such as the motor 23 or the cylinder) to work according to the calculated target position instruction. The movement of the driving member moves the concentrated mass block 21 along the guide rail 22 or in the corresponding direction to the calculated target position, and this action ensures that the natural frequency of the vibration absorber 2 matches the current main vibration frequency of the compressor 1.

[0090] In this way, when the concentrated mass block 21 is at the calculated target position, the natural frequency of the dynamic vibration absorber 2 is consistent with the main vibration frequency of the compressor 1, which means that the vibration absorber 2 starts to work efficiently, and generates vibrations with an opposite phase (phase difference of 180°) through its own resonance to cancel the vibration of the compressor 1, thereby achieving the effect of vibration reduction and noise reduction.

[0091] Furthermore, the step of controlling the driving member to start and move the concentrated mass block 21 to the target position specifically includes: calculating the to-be-adjusted direction and to-be-adjusted distance that the concentrated mass block 21 needs to move according to the target position and the current position of the concentrated mass block 21; Controlling the driving member to move the concentrated mass block 21 to the target position according to the to-be-adjusted direction and to-be-adjusted distance.

[0092] In the above embodiments, the control process further refines the steps of precisely adjusting the concentrated mass 21 to the target position, ensuring that the natural frequency of the dynamic vibration absorber 2 matches the main vibration frequency of the compressor 1. Specifically, it includes the following links: First, based on the difference between the currently detected position of the concentrated mass 21 and the target position, the system calculates and determines the direction (i.e., the direction to be adjusted) and the specific movement amount (the distance to be adjusted) that the concentrated mass 21 needs to move. This calculation process ensures the accuracy of the adjustment, making the movement purposeful. Subsequently, according to the calculated direction to be adjusted and the distance to be adjusted, the control system sends an instruction to the driving member (motor 23 or other driving devices). The driving member responds to the instruction and precisely controls the movement of the concentrated mass 21 according to the indicated direction and distance, ensuring that it slides smoothly to the predetermined target position. This process is dynamic and precise, capable of adapting to different amplitude frequency adjustment requirements.

[0093] In this way, through the above steps, this control logic not only achieves the precise positioning of the concentrated mass 21, but also ensures that the entire dynamic vibration absorber 2 can dynamically respond to the change of the vibration frequency of the compressor 1, adjust the natural frequency in real time, so as to achieve the best vibration reduction effect. This mechanism enhances the adaptability and practicability of the vibration absorber 2, optimizes the operating environment of the compressor 1, reduces noise and potential vibration problems, and improves the overall performance and user satisfaction of the air conditioning system.

[0094] In some other embodiments of the present invention, according to the comparison result between the current main vibration frequency and the previously recorded main vibration frequency of the compressor 1, the steps of controlling and adjusting the working state of the driving member specifically include: When the current main vibration frequency is equal to the previously recorded main vibration frequency of the compressor 1, control the driving member to remain closed so that the concentrated mass 21 remains in its current position unchanged.

[0095] In this embodiment, if the current main vibration frequency is the same as the previously recorded main vibration frequency of the compressor 1, it indicates that the vibration frequency of the compressor 1 has not changed significantly, or it is still in an ideal state after the previous adjustment.

[0096] In this case, the control system will adopt an energy-saving and maintaining-the-status-quo strategy, that is, control the driving member (such as the motor 23) to remain closed or stop operating. This means that the position of the concentrated mass 21 is not further adjusted, and the current arrangement state is maintained. By doing so, the natural frequency of the vibration absorber 2 continues to match the vibration frequency of the compressor 1, the vibration reduction effect is maintained, and at the same time, unnecessary energy consumption and mechanical wear are avoided.

[0097] In this way, the above method can identify when no adjustment is needed, thereby saving energy, reducing unnecessary mechanical operations, prolonging the service life of the device, and ensuring the stability and reliability of the system. Especially when the compressor 1 operates in a relatively stable frequency range or the system has reached an optimized state, the above steps can reduce the unnecessary control cost and improve the overall efficiency.
