[0046] The following introduces a dynamic vibration absorber, an air conditioner, and a control method and a control device for the air conditioner provided by the present invention with reference to the accompanying drawings. It should be pointed out that the air conditioner includes a dynamic vibration absorber, and the control method and the control device for the air conditioner provided by the present invention are both implemented on the basis of the structures of the dynamic vibration absorber and the air conditioner provided by the present invention.

[0047] like Figures 1 to 3 As shown, the dynamic vibration absorber according to the first embodiment of the present invention includes a clamping device 4, a counterweight block 2, a slide rail assembly 1 and a driving member 3.

[0048] The clamping device 4 is used to clamp and install on the piping of the air conditioner compressor, so that the dynamic vibration absorber can be fixed on the compressor piping and absorb the vibration of the piping. The counterweight block 2 is slidably connected to the slide rail assembly 1, that is, the counterweight block 2 can slide along the length direction of the slide rail assembly, and the slide rail assembly 1 is fixedly connected to the clamping device 4.

[0049] The driving member 3 is transmission-connected to the counterweight block 2, and the driving member 3 is suitable for driving the counterweight block 2 to slide along the length direction of the slide rail assembly 1. Furthermore, the driving block is used to adjust the counterweight block 2 on the slide rail assembly 1 to a preset position, wherein the preset position is calculated based on the operating frequency of the air-conditioning compressor.

[0050] Therefore, the specific working principle of the dynamic vibration absorber according to the embodiment of the present invention is as follows: when the natural frequency of the dynamic vibration absorber is the same as the excitation frequency of the system in which it is located, the dynamic vibration absorber will vibrate instead of the system, thereby achieving the effect of absorbing the vibration of the system, and the natural frequency of the dynamic vibration absorber is related to its own mass, stiffness and damping. The dynamic vibration absorber of the present invention drives the counterweight block 2 to slide through the driving member 3 to change the position of the counterweight block 2 on the sliding assembly, so as to adjust the stiffness of the dynamic vibration absorber, thereby achieving the adjustment of the natural frequency of the dynamic vibration absorber. It can be understood that the excitation frequency of the system is also the operating frequency of the compressor. Therefore, when the operating frequency of the compressor changes, the present invention can adjust the natural frequency of the dynamic vibration absorber by adjusting the position of the counterweight block 2, thereby adjusting the natural frequency of the dynamic vibration absorber to a value equal to the current operating frequency of the compressor, so as to achieve the vibration absorption function of the dynamic vibration absorber.

[0051] In the related art, during the operation of the variable frequency air conditioner compressor, the vibration of the compressor is related to its operating frequency, and the pipes such as the suction pipe and the exhaust pipe closely connected to the compressor are excited by the vibration generated during the operation of the compressor and vibrate. Since the compressor is variable frequency, the pipes vibrate excessively at multiple frequency points and the stress exceeds the standard.

[0052] However, the dynamic vibration absorber installed on the existing piping can only absorb the vibration of the piping at a single frequency point and is not suitable for variable frequency compressors. That is, the existing dynamic vibration absorber can only absorb the vibration of the piping at a single frequency point, and the vibration generated by the variable frequency compressor changes with the operating frequency. Therefore, the existing dynamic vibration absorber is not suitable for variable frequency compressors.

[0053] Therefore, in order to solve the technical defects existing in the above-mentioned related technologies, the present invention provides a dynamic vibration absorber, which can actively adjust the stiffness of the dynamic vibration absorber according to the operating frequency of the compressor, so that the dynamic vibration absorber absorbs the vibration of the piping, thereby solving the problem of excessive vibration of the piping at multiple frequency points. That is, the present invention actively controls the stiffness of the dynamic vibration absorber, changes its natural frequency, and makes the natural frequency of the dynamic vibration absorber consistent with the operating frequency of the compressor, thereby absorbing the vibration on the piping, thereby solving the problem of excessive vibration and excessive stress of the variable frequency compressor piping at multiple frequency points.

[0054] Furthermore, the specific working process of the dynamic vibration absorber of the present invention is as follows: the control system issues an instruction to control the driving component 3 to drive the counterweight block 2 to slide, thereby driving the counterweight block 2 to slide along the slide rail assembly 1. At this time, the change in the relative position of the counterweight block 2 on the slide rail assembly 1 will directly change the stiffness of the dynamic vibration absorber, thereby achieving the effect of changing the natural frequency of the dynamic vibration absorber.

[0055] Based on the theory of mechanical vibration, when the natural frequency of the dynamic vibration absorber is consistent with the excitation frequency of the system in which it is located, the dynamic vibration absorber vibrates, while the system in which it is located does not vibrate. Therefore, when the variable frequency compressor is started, the electronic control system can receive the compressor operating frequency signal, and then the electronic control system controls the driving member 3 in the dynamic vibration absorber to adjust the relative position of the counterweight block 2, and adjust the natural frequency of the dynamic vibration absorber to be consistent with the compressor operating frequency according to the pre-set program. When the variable frequency compressor continuously changes its operating frequency, the position of the counterweight block 2 in the dynamic vibration absorber is controlled by the driving member 3 to move adaptively, actively controlling the natural frequency of the dynamic vibration absorber to be consistent with the operating frequency of the variable frequency compressor, so as to achieve the effect that the dynamic vibration absorber can match the operating frequency of the compressor in real time, and finally make the dynamic vibration absorber suitable for the variable frequency compressor.

[0056] like Figures 1 to 3 As shown, according to some embodiments of the present invention, the slide rail assembly 1 includes a rack 11 and a guide rail 12, the rack 11 is slidably mounted on the guide rail 12, one end of the rack 11 is transmission-connected to the driving end of the driving member 3, and the other end of the rack 11 is fixedly connected to the counterweight 2.

[0057] In this embodiment, the rack 11 extends along the length direction of the guide rail 12, and the counterweight 2 slides on the guide rail 12 through the rack 11. Specifically, since the rack 11 is slidably connected to the guide rail 12, and the two ends of the rack 11 are respectively connected to the driving member 3 and the counterweight 2, when the driving member 3 is started, the driving section of the driving member 3 drives the rack 11 to slide along the length direction of the guide rail 12, thereby driving the counterweight 2 located at the other end of the rack 11 to slide along the guide rail 12, thereby achieving an improvement in the relative position of the counterweight 2 on the guide rail 12. In this way, the stiffness of the dynamic vibration absorber is directly changed, thereby achieving the effect of changing the natural frequency of the dynamic vibration absorber.

[0058] It should be noted that the driving member 3 may be a linear driving member 3 or a rotary driving member 3. For example, when the driving member 3 is a linear driving member 3, the driving member 3 may be a structure such as a cylinder or an oil cylinder; when the driving member 3 is a rotary driving member 3, the driving member 3 may be a structure such as a motor. The present invention does not impose any special restrictions on the structure of the driving member 3.

[0059] like Figures 1 to 3 As shown, in a specific embodiment, the driving member 3 is a motor, and a driving gear is provided at the driving end of the motor, and the driving gear is meshed with the rack 11 for transmission.

[0060] According to some embodiments of the present invention, a concave guide groove is formed in the middle of the guide rail 12 , the guide groove extends along the length direction of the guide rail 12 and both ends thereof are open, and the rack 11 can be slidably fitted in the guide groove.

[0061] In this way, the guide groove can realize a slidable connection between the rack 11 and the guide rail 12, and can ensure the stability of the connection between the rack 11 and the guide rail 12, thereby preventing the rack 11 from falling off easily, and further improving the stability of the structure.

[0062] Furthermore, a prevention eaves (not shown in the figure) extending toward the central axis of the guide rail 12 is provided at the top of the guide groove. When the rack 11 is engaged in the guide groove, the prevention eaves covers the main part of the rack 11 and exposes the tooth part of the rack 11 to the outside of the guide groove. In this way, the prevention eaves can confine the rack 11 in the guide groove, prevent the rack 11 from escaping from the guide groove in the front-to-back direction, and ensure the stability of the engagement between the rack 11 and the guide groove.

[0063] like Figures 1 to 3 As shown, according to some embodiments of the present invention, the rack 11 is installed on one outer surface of the guide rail 12 , and the clamping device 4 is installed on the other outer surface of the guide rail 12 and is located at the bottom end of the guide rail 12 .

[0064] In this way, the sliding movement of the counterweight 2 will not affect the installation and fixation of the clamping device 4.

[0065] like Figures 1 to 3 As shown, according to some embodiments of the present invention, the clamping device 4 includes a first clamping plate 41 and a second clamping plate 42 that are arranged opposite to each other. The first clamping plate 41 and the second clamping plate 42 are connected by a connecting member and define a clamping gap.

[0066] In this embodiment, when the dynamic vibration absorber needs to be installed on the compressor piping, the piping needs to be placed in the clamping gap and the piping needs to be fixed in the middle using the first clamping plate 41 and the second clamping plate 42, thereby ensuring the stable installation of the dynamic vibration absorber and improving the structural stability.

[0067] like Figures 1 to 3 As shown, according to some embodiments of the present invention, the connecting member includes two adjusting screws 43, and the two adjusting screws 43 are respectively installed at the left and right ends of the first clamping plate 41 and the second clamping plate 42, and the first clamping plate 41 and the second clamping plate 42 are suitable for adjusting the clamping gap by rotating the adjusting screws 43.

[0068] It can be understood that due to the existence of the adjusting screw 43, the clamping gap between the first clamping plate 41 and the second clamping plate 42 can be adjusted, that is, the distance between the first clamping plate 41 and the second clamping plate 42 can be adjusted. Specifically, when the size of the clamping gap needs to be adjusted to fit the size of the pipe, the adjusting screw 43 needs to be rotated to make the first clamping plate 41 or the second clamping plate 42 rise or fall, so that the length of the clamping gap can match the diameter of the pipe, so that the pipe is stably clamped in the clamping device 4, further improving the structural stability of the device.

[0069] A specific embodiment of the dynamic vibration absorber of the present invention will be described below with reference to the accompanying drawings.

[0070] like Figures 1 to 3 As shown, the dynamic vibration absorber includes a driving member 3, a slide rail assembly 1, a counterweight 2 and a clamping device 4. The driving member 3 is a motor, the slide rail assembly 1 includes a guide rail 12 and a rack 11, and the clamping device 4 includes a first clamping plate 41, a second clamping plate 42 and an adjusting screw 43.

[0071] The first clamping plate 41 and the second clamping plate 42 are mounted on the pipe by adjusting screws 43. The first clamping plate 41 located below the second clamping plate 42 is welded to the back of the guide rail 12. The guide rail 12 is fixedly connected to the body of the motor. The rotor gear of the motor is transmission-connected (meshing transmission-connected) with one end of the rack 11. A concave guide groove is provided in the middle of the guide rail 12. The rack 11 is embedded in the guide groove. The rack 11 can slide along its length relative to the guide groove. The other end of the rack 11 away from the motor is connected to the counterweight 2 by screws.

[0072] The working process of the dynamic vibration absorber is as follows: the control system issues a command to control the motor to rotate, and the motor drives the rack 11 to move along the length direction of the guide rail 12, driving the counterweight 2 at the end of the rack 11 to slide along the guide rail 12. The change in the relative position of the counterweight 2 on the guide rail 12 directly changes the stiffness of the dynamic vibration absorber, thereby achieving the effect of changing the natural frequency of the dynamic vibration absorber.

[0073] The air conditioner according to the second embodiment of the present invention comprises the dynamic vibration absorber of the first embodiment of the present invention, and also comprises a compressor and its piping. The clamping device 4 of the dynamic vibration absorber is clamped and installed on the piping of the compressor.

[0074] The air conditioner according to the embodiment of the present invention installs a dynamic vibration absorber with adjustable stiffness, and adjusts the natural frequency of the dynamic vibration absorber to be consistent with the operating frequency of the compressor according to a pre-set program. When the operating frequency of the variable frequency compressor is continuously changing, the dynamic vibration absorber is actively controlled by the motor control so that its natural frequency is consistent with the operating frequency of the variable frequency compressor, thereby achieving the effect that the dynamic vibration absorber can match its operating frequency with that of the compressor in real time, and finally makes the dynamic vibration absorber suitable for the variable frequency compressor.

[0075] The control method, control device and air conditioner of the air conditioner proposed in the present invention are described below with reference to the accompanying drawings. Among them, before the embodiment of the present invention is described in detail, the entire application scenario is described first. The control method, control device, electronic device and computer-readable storage medium of the air conditioner of the embodiment of the present invention can be applied to the air conditioner locally, and can also be applied to the cloud platform in the Internet field, or other types of cloud platforms in the Internet field, or can also be applied to third-party devices. Among them, the third-party device may include many different types such as mobile phones, tablet computers, notebooks, car computers and other smart terminals.

[0076] The following description only takes the control method applicable to air conditioners as an example. It should be understood that the control method of the embodiment of the present invention can also be applied to cloud platforms and third-party devices.

[0077] It should also be noted that the air conditioner control method proposed in the present invention is universal, that is, the method is applicable to the air conditioner for cooling or heating in a low-temperature environment or a high-temperature environment.

[0078] like Figure 4 As shown, according to the third aspect of the present invention, the control method of the air conditioner based on the second aspect of the present invention comprises:

[0079] Step S1, obtaining the current operating frequency of the compressor;

[0080] Step S2, calculating the preset position of the counterweight 2 according to the current operating frequency;

[0081] Step S3, controlling the driving member 3 to move the counterweight 2 to a preset position.

[0082] According to the control method of the air conditioner of the present invention, its specific working process is as follows: when the variable frequency compressor is started, the control system can receive the compressor operating frequency signal, at this time the control system obtains the current operating frequency of the compressor, and calculates the preset position of the counterweight 2 through the current operating frequency and other control parameters, and then the control system issues an instruction to control the motor (for example, the driving member 3) to rotate, and the motor drives the rack 11 to move along the length direction of the guide rail 12, driving the counterweight 2 at the end of the rack 11 to slide along the guide rail 12, so as to realize the change of the relative position of the counterweight 2 on the guide rail 12, thereby directly changing the stiffness of the dynamic vibration absorber, and then achieving the effect of changing the natural frequency of the dynamic vibration absorber. At this time, since the natural frequency of the vibration absorber is adjusted to be consistent with the current operating frequency of the compressor, further, based on the mechanical vibration theory, when the natural frequency of the dynamic vibration absorber is consistent with the excitation frequency of the system in which it is located, the dynamic vibration absorber vibrates, while the system in which it is located does not vibrate.

[0083] In summary, the present invention uses a newly designed air-conditioning compressor piping dynamic vibration absorber in combination with an active control method of the dynamic vibration absorber. According to the vibration absorption principle, it can have a good vibration absorption effect on vibrations generated by different frequencies of the compressor in a targeted manner, thereby realizing the applicability of the dynamic vibration absorber to the variable frequency compressor.

[0084] According to some embodiments of the present invention, in calculating the preset position where the counterweight 2 should be located according to the current operating frequency, the calculation steps of the preset position are as follows:

[0085] Obtaining a preset natural frequency of the dynamic vibration absorber according to the current operating frequency, wherein the preset natural frequency is equal to the current operating frequency;

[0086] The structural parameters of the dynamic vibration absorber are obtained, and the preset position is calculated according to the preset natural frequency and the structural parameters of the dynamic vibration absorber.

[0087] It can be understood that when the natural frequency of the dynamic vibration absorber is the same as the operating frequency of the compressor, the dynamic vibration absorber can absorb vibrations. Therefore, this embodiment obtains a preset natural frequency of equal value based on the current operating frequency, and based on the preset natural frequency and the structural parameters of the dynamic vibration absorber, calculates the preset position of the counterweight 2 when the dynamic vibration absorber reaches the preset fixed frequency.

[0088] According to some embodiments of the present invention, after controlling the driving member 3 to move the counterweight 2 to a preset position, the air conditioner control method further includes:

[0089] When it is determined that the air conditioner receives the shutdown signal, the driving component 3 is controlled to reset the counterweight 2 so that the counterweight 2 returns to the initial position.

[0090] In this way, by resetting the counterweight 2 to the initial position before shutting down the air conditioner, it is easy to adjust the position of the counterweight 2 after starting it next time, thus avoiding the occurrence of errors.

[0091] A specific embodiment of a method for controlling an air conditioner is given below with reference to the accompanying drawings.

[0092] like Figure 5 As shown, the air conditioner is turned on, and the compressor starts to run after it is turned on, and the speed gradually increases to the operating frequency of the working condition. Subsequently, the control system collects the operating frequency of the compressor, and further calculates the position of the counterweight block 2 based on the operating frequency of the compressor. After that, after calculating the preset position, the motor receives the instruction, executes the action, and moves the counterweight block 2 to the preset position. Finally, when the air conditioner is turned off, the motor executes the command to control the counterweight block 2 to reset.

[0093] The control device of the air conditioner provided by the present invention is described below. The control device of the air conditioner described below and the control method of the air conditioner described above can be referred to each other.

[0094] like Figure 6 As shown, according to the fourth aspect of the present invention, the control device of the air conditioner based on the second aspect of the present invention comprises:

[0095] An acquisition module 110 is used to acquire the current operating frequency of the compressor;

[0096] The first control module 120 is used to calculate the preset position of the counterweight 2 according to the current operating frequency;

[0097] The second control module 130 is used to control the driving member 3 to move the counterweight 2 to a preset position.

[0098] According to the control device of the embodiment of the present invention, based on the vibration absorption principle, it can have a good vibration absorption effect on the vibrations generated by the compressor at different frequencies in a targeted manner, thereby realizing the applicability of the dynamic vibration absorber to the variable frequency compressor.

[0099] Figure 7 An example of a physical structure diagram of an electronic device is shown in FIG. Figure 7 As shown, the electronic device may include: a processor 810, a communication interface 820, a memory 830 and a communication bus 840, wherein the processor 810, the communication interface 820 and the memory 830 communicate with each other through the communication bus 840. The processor 810 may call the logic instructions in the memory 830 to execute the control method of the air conditioner, including: obtaining the current operating frequency of the compressor; calculating the preset position of the counterweight block 2 according to the current operating frequency; and controlling the driving member 3 to move the counterweight block 2 to the preset position.

[0100] In addition, the logic instructions in the above-mentioned memory 830 can be implemented in the form of a software functional unit and can be stored in a computer-readable storage medium when it is sold or used as an independent product. Based on such an understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art or the part of the technical solution, can be embodied in the form of a software product, and the computer software product is stored in a storage medium, including a number of instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to perform all or part of the steps of the methods of each embodiment of the present invention. The aforementioned storage medium includes: U disk, mobile hard disk, read-only memory (ROM, Read-Only Memory), random access memory (RAM, Random Access Memory), disk or optical disk and other media that can store program codes.
