Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a shock-absorbing counterweight device, a control circuit and an air conditioner. Background Art

[0002] Pipeline vibration is a common and significant issue in the design and operation of air conditioners. Due to vibration excitation from equipment such as the compressor, the piping often experiences significant vibration. This not only impacts the piping's operating stress and shortens its service life, but also induces low-frequency noise, seriously affecting the unit's sound quality and user comfort.

[0003] Specifically, vibration in air conditioning piping primarily originates from compressor operation. Excessive compressor vibration or piping resonance significantly increases piping vibration, leading to increased internal stress and potentially fatigue damage, reducing piping reliability and service life. Furthermore, piping vibration is transmitted through the pipe sections secured to the unit's sheet metal components. Due to the large surface area of ​​sheet metal, this vibration is easily amplified and radiates low-frequency noise, further impacting the unit's sound quality and the user experience.

[0004] In order to solve the above problems, the method of regulating the natural frequency of the pipeline is usually adopted traditionally. Among them, the vibration-damping counterweight is an important pipeline vibration-damping structure. It reduces the response of the pipeline to the excitation of the vibration source by increasing the mass of the pipeline, and changes the natural frequency of the pipeline by adjusting the mass of the pipeline. However, the mass of conventional vibration-damping counterweights is usually fixed, which makes it difficult to cope with the challenges brought about by the gradually widening operating frequency of modern variable-frequency compressors. Within the operating frequency range of the variable-frequency compressor, due to the possibility of multi-order pipeline modes being excited, conventional vibration-damping counterweights have a constant mass and a fixed fixed frequency of the assembled structure, and cannot dynamically adjust the vibration reduction effect according to changes in the operating conditions of the compressor. In particular, after the vibration of the compressor increases after long-term operation, conventional vibration-damping counterweights are often unable to make corresponding vibration reduction responses according to the new excitation load, which will lead to increasingly prominent pipeline vibration problems.

[0005] Therefore, it is necessary to improve the existing shock-absorbing structure of the air-conditioning pipeline to overcome the defects of the prior art. Utility Model Content

[0045] The following describes preferred embodiments of the present invention in more detail with reference to the accompanying drawings. Although preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0046] In the prior art, vibration-damping counterweights are usually used to reduce the vibration of air-conditioning pipes. Among them, vibration-damping counterweights, as an important pipeline vibration-damping structure, reduce the response of the pipeline to the excitation of the vibration source by increasing the mass of the pipeline, and change the natural frequency of the pipeline by adjusting the mass of the pipeline. However, the mass of conventional vibration-damping counterweights is usually fixed, which makes it difficult to cope with the challenges brought about by the gradually widening operating frequency of modern variable-frequency compressors. Within the operating frequency range of the variable-frequency compressor, due to the possibility of multi-order pipeline modes being excited, conventional vibration-damping counterweights have a constant mass and a fixed fixed frequency of the assembled structure, and cannot dynamically adjust the vibration-damping effect according to changes in the operating conditions of the compressor. In particular, after the vibration of the compressor increases due to long-term operation, conventional vibration-damping counterweights are often unable to make corresponding vibration-damping responses according to the new excitation load, which will lead to increasingly prominent pipeline vibration problems.

[0047] Based on this, the present application provides a shock-absorbing counterweight device.

[0048] Example 1

[0049] like Figures 1-9 As shown, this embodiment provides a shock-absorbing counterweight device, comprising:

[0050] The mounting base 1 is detachably mounted on the pipeline, and an electromagnetic element 3 is mounted on the mounting base 1; the electromagnetic element 3 can be made of a high magnetic permeability material to effectively generate and control the magnetic field.

[0051] Permanent magnet 2 is positioned on one side of mounting base 1. A magnetic force is generated between permanent magnet 2 and electromagnetic element 3, with an appropriate gap maintained between the two elements. In practical applications, permanent magnet 2 is made of high-performance rare earth permanent magnet material, which has a high magnetic energy product and stable magnetic properties. The magnitude and direction of the magnetic force between permanent magnet 2 and electromagnetic element 3 can be varied by adjusting the relative position of permanent magnet 2 and electromagnetic element 3.

[0052] A power supply device 4 is electrically connected to the electromagnetic element 3 , and provides the electromagnetic element 3 with a current of variable magnitude.

[0053] Specifically, the mounting base 1, serving as the base for supporting the electromagnetic element 3, is detachably designed to facilitate flexible installation on the air conditioner's piping. It is suitable for air conditioning piping systems of varying models and specifications, and exhibits high flexibility and applicability. The mounting base 1 is constructed from a high-strength, corrosion-resistant material to ensure the stability and durability of the device. It should be noted that the mounting base 1 of the present application cannot be constructed from a magnetically isolating material to ensure that magnetic force can be smoothly generated between the permanent magnet 2 and the electromagnetic element 3.

[0054] The magnetic force between the electromagnetic elements 3 of the present application can be an attractive force or a repulsive force. In a specific application, the permanent magnet 2 and the electromagnetic element 3 attract each other, and the electromagnetic element 3 is attracted by the magnetic field of the permanent magnet 2 in the mounting base 1, thereby achieving the effect of generating an equivalent counterweight in the pipeline.

[0055] The power supply device 4 of the present application includes a power supply 100 and a current regulating module 41 . The current regulating module 41 is electrically connected to the power supply 100 and the electromagnetic element 3 .

[0056] In practical applications, the current regulation module 41 is electrically connected to the power supply 100 and the electromagnetic element 3, playing a key role in regulating and controlling the current. The current regulation module 41 can dynamically adjust the magnitude and direction of the current output to the electromagnetic element 3 based on an external input signal. This regulation enables precise control of the magnetic field strength generated by the electromagnetic element 3. As the magnetic field strength of the electromagnetic element 3 changes, the magnetic force between the permanent magnet 2 and the electromagnetic element 3 also changes. This allows the force exerted by the damping counterweight device on the pipeline to be adjusted, achieving optimal vibration reduction.

[0057] More specifically, the input end of the current regulating module 41 is electrically connected to the output end of the power supply 100 , and the output end of the current regulating module 41 is electrically connected to the electromagnetic element 3 . The power supply 100 of the present application may be a DC power supply 100 .

[0058] The current regulation module 41 of the present application may include a control chip, a power drive circuit, and a feedback circuit. Among them, the control chip is responsible for receiving external input signals and adjusting the current output according to a preset algorithm or real-time feedback; the power drive circuit is connected between the control chip and the electromagnetic element 3, and is responsible for amplifying the signal output by the control chip to drive the electromagnetic element 3 and change the current entering the electromagnetic element 3. The power drive circuit may include a power amplifier and an output stage, which can ensure sufficient current and voltage output to meet the working requirements of the electromagnetic element 3. The feedback circuit monitors the actual current of the electromagnetic element 3 and feeds the information back to the control chip in real time to achieve closed-loop control

[0059] The aforementioned damping and counterweight device can be used in air conditioners to adjust the stress of the air conditioner's piping. In practical applications, the mounting base 1 of the damping and counterweight device is installed at an appropriate location on the piping, based on the piping layout and vibration characteristics of the air conditioner. The current flowing through the electromagnetic element 3 is adjusted by the power supply 4, thereby varying the magnetic force between the electromagnetic element 3 and the permanent magnet 2, thereby applying a variable force to the piping. This variable force can adjust the stress distribution in the piping, effectively reducing the vibration amplitude of the piping. Furthermore, by precisely controlling the magnetic force between the electromagnetic element 3 and the permanent magnet 2, effective adjustment of the piping stress is achieved, significantly reducing the vibration noise of the piping and improving the comfort and quietness of the air conditioner.

[0060] Example 2

[0061] This embodiment is improved on the basis of embodiment 1.

[0062] In this embodiment, a specific structure of the mounting base 1 is provided.

[0063] like Figures 1-9 As shown, the mounting base 1 is provided with a slot 11, through which the mounting base 1 is engaged with the pipeline. The shape of the slot 11 is adapted to the shape of the pipeline and can completely or partially enclose the outer wall of the pipeline. The engagement of the slot 11 with the pipeline can improve the installation efficiency of the device.

[0064] In this embodiment, a clamp is further provided on the mounting seat 1 , and the clamp is provided on the periphery of the clamping groove 11 .

[0065] The mounting base 1 can be conveniently clamped onto the pipeline through the card slot 11. The shape and size of the card slot 11 are adapted and designed according to the diameter and shape of the pipeline to ensure a tight fit between the mounting base 1 and the pipeline. After the mounting base 1 is clamped onto the pipeline, the mounting base 1 is firmly fixed to the pipeline by the tightening operation of the clamp. The tightening method of the clamp can be spiral tightening, quick-release tightening or any other suitable tightening method. The specific choice depends on the actual application scenario and usage requirements. In actual applications, two clamps can be provided, and the two clamps are respectively provided at the opposite ends of the card slot 11 to ensure the force balance of the card slot 11.

[0066] Example 3

[0067] This embodiment is improved on the basis of embodiment 2.

[0068] In this embodiment, the mounting base 1 is further improved.

[0069] like Figures 1-9As shown, the mounting seat 1 is further provided with a mounting groove 12 , and the electromagnetic element 3 is arranged in the mounting groove 12 ; and when the mounting seat 1 is arranged on a pipeline, the electromagnetic element 3 is located on one side of the pipeline.

[0070] The mounting groove 12 is used to accommodate the electromagnetic element 3, allowing the electromagnetic element 3 to be firmly installed in a predetermined position, ensuring the relative position accuracy between the electromagnetic element 3 and the permanent magnet 2. Moreover, the electromagnetic element 3 is specially designed to be located on one side of the pipeline. This layout ensures that the electromagnetic element 3 maintains an appropriate distance from the pipeline, facilitating the effective transmission of magnetic force. The shape of the mounting groove 12 can be designed according to the shape of the electromagnetic element 3. More preferably, an opening is provided on one side of the mounting groove 12. After the electromagnetic element 3 is fixed to the mounting groove 12, the opening is sealed by a door panel to achieve the locking of the electromagnetic element 3.

[0071] Example 4

[0072] This embodiment is improved on the basis of embodiment 1.

[0073] In this embodiment, a stress monitoring element 5 is further included. The stress monitoring element 5 is arranged on the pipeline and is used to detect the stress level of the pipeline. The stress monitoring element 5 is electrically connected to the power supply device 4.

[0074] The stress monitoring element 5 is installed at an appropriate position on the pipeline, and is tightly attached to the pipeline surface. This installation method ensures that the stress monitoring element 5 accurately senses the deformation of the pipeline caused by mechanical vibration.

[0075] In actual applications, a controller can be used to adjust the operating state of the damping and counterweight device in real time based on the feedback signal from the stress monitoring element 5. Specifically, when the stress monitoring element 5 detects a change in pipeline stress, it transmits a corresponding signal to the power supply device 4. Based on the received signal, the power supply device 4 adjusts the magnitude and direction of the current output to the electromagnetic element 3 via the current regulation module 41, thereby changing the force exerted by the damping and counterweight device on the pipeline.

[0076] By adjusting the operating state of the damping and counterweight device in real time, the damping and counterweight device of the present application can achieve more efficient vibration and noise reduction. Whether the pipeline is operating normally or experiencing abnormal vibration, the damping and counterweight device can respond quickly, effectively reducing pipeline vibration and noise. Furthermore, the stress monitoring element 5 makes the device more intelligent. It can automatically adjust its operating state based on real-time changes in pipeline stress without manual intervention, greatly improving the system's automation and convenience.

[0077] In one application, the stress monitoring element 5 is a strain gauge. A strain gauge is an element used to measure strain, and its working principle is based on the strain effect. When a conductor or semiconductor material undergoes mechanical deformation under the action of an external force, its resistance value will change accordingly. This phenomenon is called the "strain effect." The strain gauge uses this principle to infer the strain of the material by measuring the change in resistance value. The strain gauge includes a sensitive grid, which is firmly attached to the measuring point of the pipeline when in use. When the pipeline is subjected to force and strain is generated, the sensitive grid is also deformed, resulting in a change in resistance value. This change in resistance value can be measured by a special instrument and converted into the strain value of the measuring point. Therefore, the control device of the shock absorbing and counterweight device can adjust the current of the electromagnetic element 3 according to the feedback data of the strain gauge.

[0078] Example 5

[0079] This embodiment is improved on the basis of embodiment 1.

[0080] In this embodiment, an implementation of an electromagnetic element 3 is provided.

[0081] like Figures 1-9 As shown, the electromagnetic element 3 includes a coil. When the mounting base 1 is set on the pipeline, the axis of the coil and the axis of the pipeline are set at an angle α, wherein 30°<α≤90°.

[0082] By arranging the coil axis at an angle α to the pipeline axis, the magnetic force generated between the coil and the permanent magnet 2 can better act on the pipeline, thereby more effectively adjusting the stress distribution and vibration reduction effect of the pipeline.

[0083] Preferably, α is 90°, that is, the axis of the coil and the axis of the pipeline are perpendicular to each other, and one end of the coil is located on one side of the pipeline. Through this design, after the coil is energized, under the action of the permanent magnet 2, it can generate a strong attraction or repulsion force on the pipeline, thereby achieving the purpose of adding counterweight to the pipeline.

[0084] In a more preferred implementation manner of this embodiment, the electromagnetic element 3 further includes an electromagnet 31 , the electromagnet is disposed in the coil, and the axis of the electromagnet coincides with the straight line of the coil.

[0085] By adding electromagnet 31 inside the coil, the present invention effectively enhances the magnetic field strength of electromagnetic element 3. This enhanced magnetic field enables electromagnetic element 3 to generate greater magnetic force during operation, thereby more effectively interacting with the pipeline. Furthermore, by aligning the axis of electromagnet 31 with the coil, the present invention achieves uniform magnetic field distribution, reduces magnetic field loss and energy waste, and improves the efficiency and stability of the entire system.

[0086] Example 6

[0087] This embodiment is improved on the basis of embodiment 1.

[0088] like Figure 8 As shown, this embodiment provides a control circuit, which is applied to the shock-absorbing and counterweight device described above, and the control circuit includes:

[0089] Power supply 100;

[0090] A first resistor group 200 and a second resistor group 400 are connected in parallel to the power supply 100. The first resistor group 200 includes several fixed resistors connected in series, while the second resistor group 400 includes several fixed resistors connected in series and at least one variable resistor 410. The variable resistor 410 can change its resistance according to an external control signal, thereby achieving precise regulation of the circuit current. In actual applications, the variable resistor is a strain gauge installed in a pipeline. The strain gauge can change its resistance according to the vibration of the pipeline, thereby changing the current of the control circuit.

[0091] The third resistor 300 is disposed between the first resistor group 200 and the second resistor group 400 , and one end of the third resistor 300 is connected to the variable resistor 410 .

[0092] In one application, the third resistor 300 is the output point of the power supply 100, that is, the third resistor 300 can be an electromagnetic coil. By introducing the variable resistor 410, the control circuit can flexibly adjust the current of the third resistor 300, i.e., the electromagnetic element 3, according to actual needs.

[0093] When the control circuit is operating, the power supply 100 provides electrical energy, and current sequentially flows through the first resistor group 200, the third resistor 300, and the second resistor group 400. Because the second resistor group 400 includes the variable resistor 410, the current flowing through the third resistor 300 (i.e., the electromagnetic element 3) can be flexibly changed by adjusting the resistance value of the variable resistor 410.

[0094] Specifically, in one application of the control circuit, the variable resistor is a strain gauge installed on a pipeline. When the pipeline strain increases, the resistance of the variable resistor 410 increases, the voltage at the third resistor 300 increases, and the resistance of the second resistor group 400 remains unchanged. Therefore, the current flowing through the second resistor group 400 increases, and the magnetic field strength generated at the third resistor 300 (coil) increases, thereby generating a greater electromagnetic force.

[0095] Example 8

[0096] This embodiment provides an air conditioner, including the shock-absorbing counterweight device as described above.

[0097] The air conditioner consists of two main parts: the refrigeration system and the shock-absorbing counterweight device. The refrigeration system, as the core component of the air conditioner, is responsible for achieving the cooling function. It includes key components such as the compressor, condenser, evaporator, and throttle valve. These components are connected by piping to form a closed-loop refrigeration cycle.

[0098] The shock-absorbing counterweight device, which is the object of protection requested in this application, is arranged in the pipeline of the refrigeration system. The specific structure and working principle of the shock-absorbing counterweight device have been described in detail in the aforementioned embodiments and will not be repeated here. Its main function is to effectively reduce the vibration generated by the pipeline during operation by changing the stress distribution of the pipeline, thereby ensuring the stable operation of the refrigeration system. When the air conditioner is working, the refrigeration system starts to circulate, and the compressor compresses the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas, which is then sent to the condenser for condensation and heat release, turning into a medium-temperature and high-pressure liquid. After the pressure is reduced by the throttle valve, it enters the evaporator for evaporation and heat absorption, thereby achieving a refrigeration effect. In this process, the refrigerant circulates continuously in the pipeline.

[0099] Since the flow of refrigerant in the pipes and the operation of components such as the compressor will generate certain vibrations and noise, this will not only affect the performance and service life of the air conditioner, but may also cause an uncomfortable experience for users.

[0100] Therefore, the present application provides a shock-absorbing counterweight device in the pipeline to change the stress distribution of the pipeline and reduce the vibration amplitude and frequency of the pipeline.

[0101] Specifically, when energized, electromagnetic element 3 in the damping counterweight mechanism generates a magnetic field. This magnetic field, combined with the magnetic field of permanent magnet 2, generates a magnetic force. This magnetic force interacts with the dynamic force generated by the refrigerant flowing in the pipeline, effectively adding a counterweight to the pipeline, thereby changing the pipeline's stress state. By properly adjusting the operating parameters of electromagnetic element 3, such as the current magnitude and direction, precise control of pipeline vibration can be achieved. This not only reduces the air conditioner's operating noise level and improves user comfort, but also reduces the risk of wear and leakage in the pipeline caused by long-term vibration, thereby extending the air conditioner's service life.

[0102] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0103] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0104] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
