[0002] As the living standards of residents improve, people have higher and higher requirements for air conditioning noise. At present, when air conditioners are working, resonance noise often occurs. The main factor is that the vibration frequency of the compressor coincides with the natural frequency of the box and pipeline, which produces resonance and amplifies the noise. Among them, air column resonance noise is a common noise problem in air conditioning systems. The air column resonance noise of the air conditioner outdoor unit is often transmitted to the indoor side through the refrigerant, which greatly affects people's user experience when using air conditioners. Utility Model Content

[0003] The present invention is based on the inventor's discovery and understanding of the following facts and problems:

[0004] In the related art, in order to reduce the air column resonance noise, the solution adopted is usually to change the inherent length of the refrigerant pipeline to change the air column resonance frequency of the pipeline and thus avoid the compressor exhaust pulsation frequency. However, since the actual operating frequency of the compressor is relatively wide, the improvement effect of the air column resonance noise is poor.

[0005] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0006] To this end, an embodiment of the utility model proposes a refrigerant pipeline vibration reduction structure, which can adjust the effective length of the refrigerant pipeline according to the different operating frequencies of the compressor, which is beneficial to improving the problem of air column resonance noise and improving the user experience.

[0010] In the refrigerant pipeline vibration reduction structure of the embodiment of the utility model, since the refrigerant in the first cavity can enter the second cavity through the through hole, the adjusting component can adjust the size of the flow cross section of the through hole, thereby adjusting the pressure of the refrigerant pressing the baffle along the direction from the first cavity to the second cavity. In other words, the refrigerant pressure on the baffle can be achieved by changing the flow cross section of the through hole. When the refrigerant pressure on the baffle changes, the baffle will move under the joint action of the elastic member and the refrigerant pressure, thereby changing the effective length of the refrigerant pipeline and thus changing its resonant frequency. Therefore, the refrigerant pipeline vibration reduction structure of the embodiment of the utility model can adjust the size of the flow cross section of the through hole, so that the effective length of the refrigerant pipeline can be adjusted according to the different operating frequencies of the compressor, which is conducive to improving the problem of air column resonance noise and improving the user experience.

The plurality of blocking pieces are connected to the fixed portion and correspond one-to-one to the plurality of adjustment holes. In the open position, the blocking pieces are staggered with the adjustment holes, and in the closed position, the blocking pieces are opposite to the adjustment holes.

[0014] In some embodiments, the through hole further includes a circulation hole, and when the blocking plate is in any position, the refrigerant in the first cavity can enter the second cavity through the circulation hole.

[0016] In some embodiments, the baffle is provided with a first limiting column and a second limiting column. In the open position, the blocking plate abuts against the first limiting column, and in the closed position, the blocking plate abuts against the second limiting column.

[0017] In some embodiments, the elastic member is a compression spring, which is arranged in the second cavity, one end of the compression spring abuts against the inner wall of the second cavity, and the other end of the compression spring abuts against the baffle, and the compression spring has an elastic force that drives the baffle to move toward the direction of the first cavity.

[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0036] Please refer to the following Figures 1 to 11 The invention describes a refrigerant pipeline vibration reduction structure, an air conditioner outdoor unit and an air conditioner according to embodiments of the invention.

[0037] like Figures 1 to 6 As shown, the refrigerant pipeline vibration reduction structure of the embodiment of the utility model includes: a refrigerant pipeline 1 and a vibration reduction assembly 2, and the vibration reduction assembly 2 includes an adjustment component 21, a baffle 22 and an elastic member 23.

[0038] A refrigerant flow channel 11 is provided in the refrigerant pipeline 1, and a baffle 22 is provided in the refrigerant flow channel 11 and divides the refrigerant flow channel 11 into a first cavity 111 and a second cavity 112. The first cavity 111 and the second cavity 112 are arranged along the extension direction of the refrigerant pipeline 1. A through hole 221 is provided on the baffle 22. The refrigerant in the first cavity 111 can enter the second cavity 112 through the through hole 221. The elastic member 23 is connected to the baffle 22 and presses the baffle 22 from the second cavity 112 to the first cavity 111. The baffle 22 can move along the extension direction of the refrigerant pipeline 1 under the pressure of the elastic member 23 and the refrigerant. The adjusting component 21 is connected to the baffle 22, and the adjusting component 21 is used to adjust the size of the flow cross-section of the through hole 221.

[0039] It is understandable that if Figure 3 As shown, the refrigerant flows from the first chamber 111 to the second chamber 112 (as shown in FIG. Figure 3 The elastic member 23 may flow along the direction from the second cavity 112 to the first cavity 111 (eg, Figure 3 The baffle 22 is pressed by the refrigerant (in the direction from bottom to top). When the flow cross section of the through hole 221 increases, the pressure of the refrigerant on the baffle 22 decreases, and the pressure of the refrigerant is less than the elastic force of the elastic member 23, so that the baffle 22 can move upward. Similarly, when the flow cross section of the through hole 221 decreases, the pressure of the refrigerant on the baffle 22 increases, and the pressure of the refrigerant is greater than the elastic force of the elastic member 23, so that the baffle 22 can move downward.

[0040] The air column resonance frequency of the refrigerant pipeline 1 can be expressed by the formula: f=ic / 2l.

[0041] Where: f-refrigerant pipeline gas column resonance frequency;

[0042] i = 1, 2, 3, ...;

[0043] c-sound speed in the refrigerant;

[0044] l- Length of the pipeline.

[0045] It can be seen from the above formula that the length of the refrigerant pipeline 1 directly affects the air column resonance frequency of the refrigerant pipeline 1. When the frequency or pulsation frequency of the compressor coincides with or is close to the air column resonance frequency of the refrigerant pipeline 1, the air column resonance frequency of the refrigerant pipeline 1 will be excited.

[0046] In the refrigerant pipeline vibration reduction structure of the embodiment of the utility model, since the refrigerant in the first chamber 111 can enter the second chamber 112 through the through hole 221, the adjusting component 21 can adjust the size of the flow cross section of the through hole 221, thereby adjusting the pressure of the refrigerant pressing the baffle 22 along the direction from the first chamber 111 to the second chamber 112. In other words, the refrigerant pressure on the baffle 22 can be achieved by changing the flow cross section of the through hole 221. When the refrigerant pressure on the baffle 22 changes, under the joint action of the elastic member 23 and the refrigerant pressure, the baffle 22 will move, thereby changing the effective length of the refrigerant pipeline 1, and then changing its resonant frequency.

[0047] In other words, the adjustment of the effective length of the refrigerant pipeline 1 is achieved by changing the position of the baffle 22 inside the refrigerant pipeline 1. The air conditioning system can obtain the pressure pulsation frequency inside the system according to the operating frequency of the compressor. The regulating component 21 adjusts the size of the through hole 221 on the baffle 22 to adjust the size of the refrigerant pressure on the baffle 22, thereby adjusting the position of the baffle 22, thereby allowing the pipeline air column resonance frequency to avoid the compressor pulsation frequency, avoiding the noise problem caused by the air column resonance generated in the refrigerant pipeline 1.

[0048] Therefore, the refrigerant pipeline vibration reduction structure of the embodiment of the utility model can adjust the size of the flow cross-section of the through hole 221, so that the effective length of the refrigerant pipeline 1 can be adjusted according to the different operating frequencies of the compressor, which is beneficial to improving the problem of air column resonance noise and improving the user experience.

[0049] Alternatively, if Figure 3 and Figure 4 As shown, the regulating component 21 includes a driving motor 211 and a blocking plate 212. The driving motor 211 is disposed on the baffle 22 and connected to the blocking plate 212. The driving motor 211 can drive the blocking plate 212 to move between an open position for opening the through hole 221 and a closed position for closing the through hole 221. It can be understood that the driving motor 211 can drive the blocking plate 212 to move to open and close the through hole 221. It should be noted that in the closed position, the blocking plate 212 can retain the ability of the through hole 221 to circulate a portion of the refrigerant, that is, the blocking plate 212 in the closed position does not completely close the through hole 221.

[0050] The drive motor 211 is connected to the compressor for communication. The drive motor 211 can adjust the area of ​​the through hole 221 blocked by the blocking plate 212 according to the operating frequency of the compressor, thereby changing the refrigerant pressure on the baffle 22 to adjust the position of the baffle 22.

[0051] For example, the driving motor 211 can drive the blocking plate 212 to translate to open and block the through hole 221. For another example, the driving motor 211 can drive the blocking plate 212 to rotate to open and block the through hole 221.

[0052] In the example of this application, Figure 3 As shown, the blocking plate 212 is arranged on one side of the baffle 22 in the thickness direction, the output shaft of the driving motor 211 is passed through the baffle 22 and is connected to the blocking plate 212, and the driving motor 211 can drive the blocking plate 212 to rotate between the open position and the closed position. It can be understood that the driving motor 211 is fixed on the baffle 22 and can move with the movement of the baffle 22. In the open position, the blocking plate 212 is staggered from the through hole 221. In the closed position, the blocking plate 212 is opposite to the through hole 221. The refrigerant pipeline vibration reduction structure of the embodiment of the utility model can reduce the size of the vibration reduction assembly 2 by designing the adjustment component 21 as the above-mentioned structure, and the structure is simple and easy to process and manufacture.

[0053] Alternatively, if Figure 5 and Figure 6 As shown, the through hole 221 includes a plurality of adjustment holes 2211, and the plurality of adjustment holes 2211 are arranged at intervals on the baffle 22, and the blocking plate 212 includes a fixed portion 2121 and a plurality of blocking pieces 2122, the fixed portion 2121 is connected to the drive motor 211, and the plurality of blocking pieces 2122 are connected to the fixed portion 2121, and the plurality of blocking pieces 2122 correspond one to one with the plurality of adjustment holes 2211. In the open position, the blocking pieces 2122 are staggered from the adjustment holes 2211, and in the closed position, the blocking pieces 2122 are opposite to the adjustment holes 2211. The refrigerant pipeline vibration reduction structure of the embodiment of the utility model can improve the uniformity of the refrigerant flowing through the baffle 22 and reduce the resistance of the refrigerant when flowing by designing the through hole 221 and the blocking plate 212 as the above-mentioned structure.

[0054] In the example of the present application, there are three blocking pieces 2122, which are arranged at equal intervals along the circumference of the fixing portion 2121. There are three adjustment holes 2211, which correspond to the three blocking pieces 2122 and the three adjustment holes 2211 one by one.

[0055] In some embodiments, Figure 6 As shown, the through hole 221 also includes a circulation hole 2212. When the blocking plate 212 is in any position, the refrigerant in the first cavity 111 can enter the second cavity 112 through the circulation hole 2212. It can be understood that when in the closed position, the blocking plate 212 can completely close the adjustment hole 2211, and the circulation hole 2212 is still connected to the first cavity 111 and the second cavity 112. When in the open position, the adjustment hole 2211 and the circulation hole 2212 are both connected to the first cavity 111 and the second cavity 112. In this way, the refrigerant can flow normally in the refrigerant pipeline 1 without affecting the cooling effect of the air conditioner outdoor unit.

[0056] Optionally, there are multiple flow holes 2212, which are arranged at intervals around the circumference of the output shaft on the baffle 22. In the example of the present application, there are three flow holes 2212, which are arranged at equal intervals along the circumference of the output shaft.

[0057] In other examples, the outer peripheral wall of the baffle 22 and the inner peripheral wall of the refrigerant pipeline 1 define the flow hole 2212. This can avoid directly opening a hole on the baffle 22, reduce the processing steps of the baffle 22, and reduce the production cost.

[0058] like Figure 4 and Figure 7 As shown, the baffle plate 22 is provided with a first limiting column 222 and a second limiting column 223. When in the open position, the blocking plate 212 abuts against the first limiting column 222, and when in the closed position, the blocking plate 212 abuts against the second limiting column 223. It can be understood that the first limiting column 222 and the second limiting column 223 can limit the movement of the blocking plate 212 to improve the accuracy of the movement of the blocking plate 212.

[0059] In some embodiments, Figure 3 As shown, the elastic member 23 is a compression spring, which is arranged in the second cavity 112, one end of the compression spring abuts against the inner wall of the second cavity 112, and the other end of the compression spring abuts against the baffle 22, and the compression spring has an elastic force that drives the baffle 22 to move toward the first cavity 111. This makes it easier to process and assemble the refrigerant pipeline vibration reduction structure.

[0060] For example, Figure 2 As shown, a stop ring 12 is provided in the second cavity 112, and the stop ring 12 is provided at one end of the second cavity 112 away from the baffle 22, and the other end of the compression spring abuts against the stop ring 12. Thus, the stop ring 12 can axially limit the compression spring and facilitate the assembly of the compression spring.

[0061] Another embodiment of the air conditioner outdoor unit of the utility model comprises: a housing, a compressor and a refrigerant pipeline vibration reduction structure. The compressor is arranged in the housing, the refrigerant pipeline vibration reduction structure is the refrigerant pipeline vibration reduction structure of the utility model, and one end of the refrigerant pipeline 1 is connected to the compressor.

[0062] According to another embodiment of the air conditioner outdoor unit of the present utility model, since the refrigerant in the first chamber 111 can enter the second chamber 112 through the through hole 221, the adjusting component 21 can adjust the size of the flow cross section of the through hole 221, thereby adjusting the pressure of the refrigerant pressing the baffle 22 along the direction from the first chamber 111 to the second chamber 112. In other words, the refrigerant pressure on the baffle 22 can be achieved by changing the flow cross section of the through hole 221. When the refrigerant pressure on the baffle 22 changes, under the joint action of the elastic member 23 and the refrigerant pressure, the baffle 22 will move, thereby changing the effective length of the refrigerant pipeline 1, and then changing its resonant frequency. Therefore, the air conditioner outdoor unit of the embodiment of the present utility model can adjust the size of the flow cross section of the through hole 221, so that the effective length of the refrigerant pipeline 1 can be adjusted according to the different operating frequencies of the compressor, which is conducive to improving the problem of air column resonance noise and improving the user's experience.

[0063] An air conditioner of another embodiment of the utility model comprises an air conditioner outdoor unit and an air conditioner indoor unit, the air conditioner outdoor unit is the air conditioner outdoor unit of the utility model, and the other end of the refrigerant pipe 1 is connected to the air conditioner indoor unit. The technical advantages of the air conditioner of the utility model embodiment are the same as the technical advantages of the refrigerant pipe vibration reduction structure or the air conditioner outdoor unit of the above embodiment, and will not be repeated here.
