Description

Technical Field

[0001] The present application relates to the field of household appliance technology, for example, to a refrigerant pipe fixing device and a control method and storage medium thereof. Background Art

[0002] At present, most refrigeration equipment uses a compressor in conjunction with a refrigerant pipe for refrigeration. Since the compressor will generate vibration during operation, it will drive the entire refrigerant pipe to vibrate. On the one hand, it causes excessive noise. On the other hand, long-term vibration can easily cause the interface to loosen, affecting the overall stability of use.

[0003] In order to reduce the vibration of the refrigerant pipe in the related technology, most of them use fixing components to increase the fixing force of the refrigerant pipe, but this still cannot avoid the vibration of the refrigerant pipe, and most of the compressors at this stage are variable frequency compressors. As the operating frequency of the compressor changes, its vibration frequency changes, which is easy to resonate with the refrigerant pipe, thereby aggravating the vibration amplitude of the refrigerant pipe, generating excessive noise, and reducing the overall service life of the refrigerant pipe.

[0004] It can be seen that how to avoid resonance between the compressor and the refrigerant pipe, reduce the vibration amplitude of the refrigerant pipe, improve the overall stability of the refrigerant pipe, and reduce the noise of the refrigerant pipe have become technical problems that need to be urgently solved by technical personnel in this field.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0009] In some embodiments, a control method for a refrigerant pipe fixing device includes:

[0010] Determine the vibration frequency of the compressor;

[0011] Obtain the vibration frequency of the refrigerant pipe;

[0012] According to the difference between the vibration frequency of the compressor and the vibration frequency of the refrigerant pipe, the liquid pump component is controlled to adjust the amount of liquid in the liquid storage chamber.

[0013] In some embodiments, the storage medium stores program instructions, and when the program instructions are run, they execute the control method for the refrigerant pipe fixing device of any of the above embodiments.

During the adjustment process, the vibration frequency of the refrigerant pipe and the compressor is determined in real time by the vibration sensor and the compressor frequency determination module, and then the amount of liquid in the liquid storage chamber inside the fixed rubber block is adjusted according to the frequency of the refrigerant pipe and the compressor, so that the overall vibration frequency of the refrigerant pipe fixing device avoids the frequency of the compressor, avoiding resonance between the refrigerant pipe and the compressor, which can effectively reduce the vibration amplitude of the refrigerant pipe, reduce noise, reduce the stress risk of the refrigerant pipe, improve the overall stability of the refrigerant pipe fixing device, and utilize the energy absorption characteristics of the fluid to reduce the amplitude, reduce the vibration stress, and reduce noise.

[0038] Combination Figure 1-5 As shown, the embodiment of the present disclosure provides a refrigerant pipe fixing device including: a fixed rubber block 200, a liquid pump assembly 300, a vibration sensor 400, a compressor frequency determination module 500 and a controller assembly 600. The fixed rubber block 200 is fixedly connected to a plurality of refrigerant pipes, and a liquid storage chamber 201 is provided inside the fixed rubber block 200; the liquid pump assembly 300 is in communication with the liquid storage chamber 201, and is used to control the amount of liquid flowing into the liquid storage chamber 201; the vibration sensor 400 is arranged on the refrigerant pipe and / or the fixed rubber block 200, and is used to detect the vibration frequency of the refrigerant pipe; the compressor frequency determination module 500 is used to obtain the vibration frequency of the compressor; the controller assembly 600 is connected to the liquid pump assembly 300, the vibration sensor 400 and the compressor frequency determination module 500, and is used to control the liquid pump assembly 300 to adjust the amount of liquid in the liquid storage chamber 201 according to the vibration frequency of the refrigerant pipe detected by the vibration sensor 400 and the vibration frequency of the compressor obtained by the compressor frequency determination module 500.

[0039] By adopting the refrigerant pipe fixing device provided by the embodiment of the present disclosure, the refrigerant pipe is fixed by the fixed rubber block 200, so that the vibration amplitude of the refrigerant pipe can be reduced, and a liquid storage chamber 201 is set in the fixed rubber block 200. By filling liquid into the liquid storage chamber 201, the weight of the entire fixed rubber block 200 is changed, and the vibration frequency of the fixed rubber block 200 and the refrigerant pipe connected to the fixed rubber block 200 can be changed. During the adjustment process, the vibration frequency of the refrigerant pipe and the compressor is determined in real time by the vibration sensor 400 and the compressor frequency determination module 500, and then the amount of liquid in the liquid storage chamber 201 inside the fixed rubber block 200 is adjusted according to the frequency of the refrigerant pipe and the compressor, so that the overall vibration frequency of the refrigerant pipe fixing device avoids the frequency of the compressor, and resonance between the refrigerant pipe and the compressor is avoided. The vibration amplitude of the refrigerant pipe can be effectively reduced, noise can be reduced, the stress risk of the refrigerant pipe can be reduced, and the overall stability of the refrigerant pipe fixing device can be improved. The energy absorption characteristics of the fluid can be used to reduce the amplitude, reduce the vibration stress, and reduce noise.

[0040] Optionally, the liquid pump assembly 300 is also connected to the liquid storage box 305, and the liquid pump assembly 300 is used to input the liquid in the liquid storage box 305 into the liquid storage chamber 201, or input the liquid in the liquid storage chamber 201 into the liquid storage box 305. In this way, the liquid is stored by the liquid storage box 305, which is convenient for controlling the amount of liquid in the liquid storage chamber 201 in cooperation with the liquid pump assembly 300.

[0041] Optionally, a viscous liquid is stored in the liquid storage box 305. In this way, the viscosity of the viscous liquid is utilized to better absorb the energy of the vibration during the vibration process, thereby suppressing the increase of the vibration amplitude and achieving a better vibration reduction effect.

[0042] It can be understood that the viscous liquid may be glycerin or the like.

[0043] Optionally, the liquid pump assembly 300 includes: a pump body 301, a reflux valve 302, a liquid quantity detection assembly 303 and a liquid quantity control assembly 304. The liquid outlet end of the pump body 301 is connected to the liquid storage chamber 201, and is used to fill the liquid storage chamber 201 with liquid; the reflux valve 302 is connected to the liquid storage chamber 201, and is used to reflux and discharge the liquid in the liquid storage chamber 201; the liquid quantity detection assembly 303 is arranged on the fixed rubber block 200, and is used to detect the liquid quantity in the liquid storage chamber 201; the liquid quantity control assembly 304 is respectively connected to the pump body 301, the reflux valve 302 and the liquid quantity detection assembly 303, and is used to control the pump body 301 or the pressure relief valve to adjust the liquid quantity in the liquid storage chamber 201 according to the actual liquid quantity detected by the liquid quantity detection assembly 303 after obtaining the target liquid quantity, so that the target liquid quantity is reached. In this way, the liquid pump assembly 300 includes a pump body 301 and a reflux valve 302. By filling the liquid storage chamber 201 with liquid or discharging the liquid in the liquid storage chamber 201, the amount of liquid in the liquid storage chamber 201 is changed, thereby changing the weight of the entire fixed rubber block 200. On the one hand, the liquid in the liquid storage chamber 201 can be used to absorb energy and reduce the amplitude. On the other hand, the weight of the fixed rubber block 200 has an impact on its vibration frequency. By changing the weight of the fixed rubber block 200, its vibration frequency can be adjusted so that its vibration frequency avoids the vibration frequency of the compressor, thereby avoiding resonance between the refrigerant pipe and the compressor. A liquid amount detection assembly 303 is set in the liquid storage chamber 201 to obtain the amount of liquid in the liquid storage chamber 201 in real time, and feed it back to the pump body 301 and the reflux valve 302. The amount of liquid in the liquid storage chamber 201 can be adjusted more accurately, and the vibration frequency of the refrigerant pipe can be stably controlled to change, thereby avoiding resonance between the refrigerant pipe and the compressor.

[0044] Optionally, the pump body 301 is a small high-pressure water pump. In this way, liquid can be better transported into the liquid storage chamber 201, and liquid can also be transported into the liquid storage chamber 201 when there is sufficient pressure in the liquid storage chamber 201.

[0045] Optionally, the liquid amount detection component 303 is a pressure sensor, which determines the amount of liquid in the liquid storage chamber 201 by acquiring the pressure in the liquid storage chamber 201. In this way, since the liquid storage chamber 201 is a closed structure, when liquid is transported into the liquid storage chamber 201, the pressure in the liquid storage chamber 201 will increase. Therefore, by detecting the pressure in the liquid storage chamber 201, the amount of liquid in the liquid storage chamber 201 can be determined more simply and accurately.

[0046] Optionally, the reflux valve 302 includes: a one-way valve 306 and a push pin 307. The one-way valve 306 liquid storage chamber 201 is connected to the pump body 301 through the one-way valve 306 that can be switched; the push pin 307 can push up the one-way valve 306 to make the liquid in the liquid storage chamber 201 flow out. In this way, by setting the one-way valve 306, when the liquid storage chamber 201 is filled with liquid, the liquid can be prevented from flowing out in the reverse direction, and the liquid in the liquid storage chamber 201 can be stably maintained. When the liquid needs to be discharged, the push pin 307 can be controlled to push up the one-way valve 306 to discharge the liquid. The overall structure is simple and has high stability.

[0047] Optionally, the liquid storage chamber 201 is a closed chamber defined in the fixed rubber block 200, and when the liquid is filled in the liquid storage chamber 201, the fixed rubber block 200 can be squeezed to change the hardness of the fixed rubber block 200. In this way, liquid can be filled in the liquid storage chamber 201 to squeeze the liquid storage chamber 201, and the hardness of the fixed rubber block 200 can be increased by squeezing the liquid, thereby increasing the fixing force of the fixed rubber block 200 on the refrigerant pipe, changing the vibration frequency of the refrigerant pipe, further preventing resonance between the refrigerant pipe and the compressor, maintaining the stability of the refrigerant pipe, and avoiding the increase in amplitude, which causes the risk of increased stress on the refrigerant pipe.

[0048] Optionally, the liquid storage chamber 201 is arranged at the center of the fixed rubber block 200. In this way, the liquid storage chamber 201 is arranged at the center of the fixed rubber block 200, and when the amount of liquid inside the liquid storage chamber 201 increases, the fixed rubber block 200 can be uniformly pressed to the surroundings, thereby uniformly improving the hardness of each position of the fixed rubber block 200, and then the vibration frequency of multiple refrigerant pipes can be adjusted synchronously, so that the vibration frequency of each refrigerant pipe is kept as consistent as possible.

[0049] Optionally, the shape of the liquid storage cavity 201 is the same as that of the fixed rubber block 200. In this way, when the liquid storage cavity 201 is located at the center of the fixed rubber block 200, the liquid storage cavity 201 can be adapted to the fixed rubber block 200, and the liquid storage cavity 201 can be evenly transferred to the fixed rubber block 200 when subjected to pressure, so that the hardness changes of various positions of the fixed rubber block 200 remain uniform, thereby maintaining a uniform fixing effect on multiple refrigerant pipes.

[0050] Optionally, the vibration sensor 400 is provided with a plurality of sensing parts, and is respectively arranged on a plurality of refrigerant pipes and the fixed rubber block 200. In this way, the vibrations on the refrigerant pipes and the fixed rubber block 200 can be detected by the plurality of sensing parts, and the vibration frequencies of each part can be integrated to improve the accuracy of the detection.

[0051] Optionally, the fixed rubber block 200 is provided with a plurality of pipe fixing holes 202, and the pipe fixing holes 202 are used to fix the refrigerant pipe. In this way, the refrigerant pipe can pass through the pipe fixing holes 202 on the fixed rubber block 200, so as to better fix the refrigerant pipe, and the refrigerant pipe is fixed by a sleeve connection method, so that the connection between the fixed rubber block 200 and the refrigerant pipe is more flexible and easy to adjust.

[0052] Optionally, the fixing rubber block 200 is a polygonal structure, and the pipe fixing holes 202 are arranged at the corners of the polygonal structure. In this way, the refrigerant pipe is fixed at the corners of the fixing rubber block 200, and the refrigerant pipe can be fixed from the position between multiple refrigerant pipes, reducing the space occupied by the fixing rubber block 200, and separating multiple refrigerant pipes by a certain distance to prevent the refrigerant pipes from affecting each other.

[0053] The shape of the fixing rubber block 200 is related to the number of refrigerant pipes it fixes. For example, when the fixing rubber block 200 is used to fix three refrigerant pipes, it has a triangular structure and uses the positions of the three vertices to fix the refrigerant pipes respectively.

[0054] Optionally, the pipeline fixing hole 202 is arranged at the edge of the fixing rubber block 200 and has an opening 203 facing the edge of the fixing rubber block 200. In this way, it is convenient to insert the refrigerant pipe into the pipeline fixing hole 202 through the opening 203 on the edge of the fixing rubber block 200, thereby improving the convenience of connection between the refrigerant pipe and the fixing rubber block 200 and facilitating the removal and installation of the fixing rubber block 200.

[0055] Optionally, the pipeline fixing hole 202 is circular, and its diameter is less than or equal to the diameter of the refrigerant pipe, so that the refrigerant fixing hole 202 can be filled when the refrigerant pipe is fixed in the pipeline fixing hole 202, and the elasticity of the fixing rubber block 200 is fully utilized to improve the fixing effect of the refrigerant pipe.

[0056] Combination Figure 6 As shown, the embodiment of the present disclosure provides a control method for a refrigerant pipe fixing device, including:

[0057] S01, determining the vibration frequency of the compressor;

[0058] S02, obtaining the vibration frequency of the refrigerant pipe;

[0059] S03, controlling the liquid pump assembly to adjust the amount of liquid in the liquid storage chamber according to the difference between the vibration frequency of the compressor and the vibration frequency of the refrigerant pipe.

[0060] By adopting the control method for the refrigerant pipe fixing device provided in the embodiment of the present disclosure, the vibration frequencies of the refrigerant pipe and the compressor can be determined in real time, and the amount of liquid in the liquid storage chamber in the fixed rubber block can be adjusted according to the frequencies of the refrigerant pipe and the compressor, thereby changing the vibration frequency of the refrigerant pipe so that the vibration frequency of the refrigerant pipe avoids the frequency of the compressor, thereby avoiding resonance between the refrigerant pipe and the compressor, which can effectively reduce the vibration amplitude of the refrigerant pipe, reduce noise, eliminate the stress risk of the refrigerant pipe, and improve the overall stability of the refrigerant pipe.

[0061] Optionally, S01, obtaining the vibration frequency of the compressor includes: connecting the compressor frequency determination module to the processor of the refrigeration equipment, and determining the current operating frequency of the compressor by extracting its system operation data. In this way, the vibration frequency of the compressor can be obtained more accurately and conveniently. Generally, the vibration frequency of the compressor is directly related to its operating frequency. Based on this, the vibration frequency of the compressor can be efficiently determined, thereby facilitating the control of the vibration frequency of the refrigerant pipe to avoid the vibration frequency of the compressor, thereby avoiding the resonance of the refrigerant pipe and the compressor, resulting in an increase in the amplitude.

[0062] It can be understood that the vibration frequency of the compressor can also be directly obtained by setting a sensor on the compressor.

[0063] Optionally, S02, obtaining the vibration frequency of the refrigerant pipe includes: in the case where multiple sensing parts of the vibration sensors are provided on the refrigerant pipe fixing device, obtaining the vibration frequency data detected by the multiple sensing parts, and calculating the average value of the multiple vibration frequency data, and determining the average value as the vibration frequency of the refrigerant pipe. In this way, by detecting the vibration frequency data of multiple positions on the refrigerant pipe fixing device and calculating the average value thereof, the vibration frequency of the entire refrigerant pipe can be more accurately reflected, and the measurement error can be reduced.

[0064] like Figure 7 As shown, optionally, S03, according to the difference between the vibration frequency of the compressor and the vibration frequency of the refrigerant pipe, controlling the liquid pump assembly to adjust the amount of liquid in the liquid storage chamber includes:

[0065] S31, calculating the difference between the vibration frequency of the compressor and the vibration frequency of the refrigerant pipe;

[0066] S32, when it is determined that the difference between the vibration frequency of the compressor and the vibration frequency of the refrigerant pipe is greater than or equal to the first threshold, controlling the liquid pump assembly to maintain the current amount of liquid in the liquid storage chamber;

[0067] S33, when it is determined that the difference between the vibration frequency of the compressor and the vibration frequency of the refrigerant pipe is less than a first threshold, controlling the liquid pump assembly to increase or decrease the amount of liquid in the liquid storage chamber.

[0068] In this way, the resonance between the compressor and the refrigerant pipe means that the vibration frequencies of the two are the same. Therefore, taking into account the detection error of the vibration sensor, when it is detected that the difference between the two is greater than or equal to the first threshold value, it means that there is an obvious difference in the vibration frequencies between the two, and no resonance will occur. At this time, maintaining the current liquid amount in the liquid storage chamber in the fixed rubber block can avoid resonance between the compressor and the refrigerant pipe. When the difference between the two is less than the first preset value, it means that the vibration frequencies between the two are relatively close. At this time, the possibility of resonance between the compressor and the refrigerant pipe fixing device is high. At this time, by increasing or decreasing the liquid amount in the liquid storage chamber in the fixed rubber block, the vibration frequency of the refrigerant pipe can be changed, so that the vibration frequencies between the two are widened to a certain extent, thereby effectively avoiding resonance between the compressor and the refrigerant pipe, avoiding excessive vibration amplitude, effectively reducing noise, eliminating stress risks of the refrigerant pipe, and improving the stability of the refrigerant pipe.

[0069] Optionally, the value of the first threshold is determined according to the vibration frequency of the compressor. In this way, since the vibration of the compressor is the source of the vibration, the first threshold is determined according to the vibration frequency of the compressor, and the vibration frequency of the refrigerant pipe is controlled accordingly, which can effectively prevent the vibration frequency of the refrigerant pipe from approaching the vibration frequency of the compressor, reduce the risk of resonance, and improve the stability of the overall refrigerant pipe.

[0070] Optionally, the first threshold is 1% to 3% of the vibration frequency of the compressor. Preferably, the first threshold is 2% of the vibration frequency of the compressor. In this way, under normal circumstances, when the vibration frequencies of two objects are close to within 3%, there will be a risk of resonance. Therefore, the first threshold is set within 1% to 3%. When the difference between the vibration frequency of the compressor and the vibration frequency of the refrigerant pipe is less than 1% to 3% of the vibration frequency of the compressor, the liquid pump assembly is controlled to adjust the amount of liquid in the liquid storage cavity of the fixed rubber block, so that the vibration frequency of the refrigerant pipe changes, better avoiding resonance between the compressor and the refrigerant pipe, eliminating the stress risk of the refrigerant pipe, and improving the stability of the refrigerant pipe.

[0071] For example, when the first threshold is 2% of the vibration frequency of the compressor, and the vibration frequency of the compressor is 50 Hz, the value of the first threshold is 1 Hz.

[0072] like Figure 8 As shown, optionally, S33, when it is determined that the difference between the vibration frequency of the compressor and the vibration frequency of the refrigerant pipe is less than a first threshold, controlling the liquid pump assembly to increase or decrease the amount of liquid in the liquid storage chamber includes:

[0073] S34, obtaining the current amount of liquid in the liquid storage chamber;

[0074] S35, when it is determined that the current amount of liquid in the liquid storage chamber is in the first preset area, controlling the liquid pump assembly to increase the amount of liquid in the liquid storage chamber;

[0075] S36, when it is determined that the current amount of liquid in the liquid storage chamber is in the second preset area, controlling the liquid pump assembly to reduce the amount of liquid in the liquid storage chamber.

[0076] In this way, when it is necessary to adjust the amount of liquid in the liquid storage chamber in the fixed rubber block, the current amount of liquid in the liquid storage chamber can be obtained, and according to the range of the liquid amount in the liquid storage chamber, the liquid storage chamber adjustment mechanism is controlled to increase or decrease the amount of liquid in the liquid storage chamber. When the current amount of liquid in the liquid storage chamber is high, the amount of liquid in the liquid storage chamber is reduced, and when the current amount of liquid in the liquid storage chamber is low, the amount of liquid in the liquid storage chamber is increased. The liquid amount in the liquid storage chamber can be reasonably adjusted within the adjustable range, thereby changing the vibration frequency of the refrigerant pipe, preventing resonance between the refrigerant pipe fixing device and the compressor, and preventing the liquid amount in the liquid storage chamber of the fixed rubber block from exceeding its adjustable range when adjusting the liquid amount, causing damage to the fixed rubber block, or failure of the adjustment.

[0077] Optionally, the adjustable range of the amount of liquid in the liquid storage chamber is determined, the first preset area is the first half of the adjustable range of the amount of liquid in the liquid storage chamber, and the second preset area is the second half of the adjustable range of the amount of liquid in the liquid storage chamber, wherein the range of the first preset area is larger than the range of the second preset area. In this way, the first preset area is the first half of the adjustable range of the amount of liquid in the liquid storage chamber, so when the current amount of liquid is in the first preset area, it means that the amount of liquid in the liquid storage chamber has room to be increased, so the amount of liquid in the liquid storage chamber is controlled to increase, and conversely, when it is in the second preset area, the amount of liquid in the liquid storage chamber can be controlled to decrease, wherein the range of the first preset area is larger than the second preset area, which can increase the probability of increasing the amount of liquid in the liquid storage chamber during the adjustment stage, give priority to increasing the amount of liquid in the liquid storage chamber, and can improve the fixing effect of the refrigerant pipe.

[0078] Optionally, the adjustable range of the liquid volume in the liquid storage chamber is determined, the first preset area is the first four fifths of the adjustable range of the liquid volume in the liquid storage chamber, and the second preset area is the last one fifth of the adjustable range of the liquid volume in the liquid storage chamber. In this way, by determining the adjustable range of the liquid volume in the liquid storage chamber, the adjustment strategy for the liquid storage chamber is controlled. When the current liquid volume in the liquid storage chamber is in the first four-fifths of the adjustable range of the liquid volume, it means that the liquid volume in the liquid storage chamber still has room for upward adjustment. Therefore, it is prioritized to increase the liquid volume in the liquid storage chamber, which can change the vibration frequency of the refrigerant pipe, thereby widening the gap between it and the vibration frequency of the compressor to avoid resonance. At the same time, increasing the liquid volume in the liquid storage chamber can further squeeze the fixed rubber block to increase the fixing force on the refrigerant pipe, reduce the vibration amplitude of the refrigerant pipe, and better reduce shock and noise. When the current liquid volume in the liquid storage chamber is in the last one-fifth of the adjustable range of its liquid volume, it means that the liquid volume in the liquid storage chamber is about to reach the upper limit. At this time, continuing to increase the adjustment may easily cause damage to the fixed rubber block, or the adjustment demand cannot be met after reaching the upper limit of the liquid volume in the liquid storage chamber. Therefore, it is prioritized to reduce the liquid volume in the liquid storage chamber so that the adjustable range is larger, which can better ensure that the vibration frequency of the refrigerant pipe is widened by the vibration frequency of the compressor to avoid resonance.

[0079] It can be understood that the vibration frequency of the refrigerant pipe fixing device referred to above refers to the average value of the vibration frequencies at multiple positions of the refrigerant pipe and the fixing rubber block.

[0080] like Fig. 9 As shown, the embodiment of the present disclosure provides another control method for a refrigerant pipe fixing device, including:

[0081] S04, controlling the liquid storage chamber adjustment mechanism to adjust the liquid volume in the liquid storage chamber to a maximum value within an adjustable range of the liquid volume;

[0082] S05, when it is determined that the difference between the vibration frequency of the compressor and the vibration frequency of the refrigerant pipe is less than a first threshold, controlling the liquid storage chamber adjustment mechanism to reduce the amount of liquid in the liquid storage chamber.

[0083] In this way, the initial liquid amount in the liquid storage chamber of the fixed rubber block is set to the maximum value, which can provide a higher fixing force for the refrigerant pipe during the startup phase of the compressor, effectively suppress the vibration of the refrigerant pipe, and enable the fixed rubber block to exert the best fixing force when there is no risk of resonance between the refrigerant pipe and the compressor, thereby improving the overall stability of the refrigerant pipe. When the difference between the vibration frequency of the compressor and the vibration frequency of the refrigerant pipe is less than the first threshold value, and it is determined that there is a risk of resonance between the compressor and the refrigerant pipe, the vibration frequency of the refrigerant pipe is changed by reducing the liquid amount in the liquid storage chamber, thereby widening the gap between the vibration frequency of the refrigerant pipe and the compressor, thereby avoiding resonance between the two.
