Description

Technical Field

[0001] This utility model relates to the field of air handling equipment, and in particular to a compressor air pipe, an outdoor air conditioning unit, and an air conditioner. Background Technology

[0002] Existing household and small commercial air conditioners generally use rotary compressors. The compressor rotates periodically to drive the refrigerant circulation, and the heat exchange between the refrigerant and air is achieved through the evaporator, expansion valve, and condenser to achieve cooling and heating functions. However, because the compressor rotates periodically, it drives the exhaust pipe and suction pipe connected to the compressor to rotate periodically, and the refrigerant is discharged periodically. This causes periodic misalignment of the exhaust pipe and suction pipe, generating stress. Especially when the compressor speed causes resonance or excessive vibration, the amplitude and stress of the exhaust pipe and suction pipe become too large, resulting in abnormal noise and damage to the exhaust pipe and suction pipe. Summary of the Invention

[0003] Based on this, the purpose of this utility model is to overcome the defects or deficiencies of the prior art and provide a compressor air pipe whose structure can improve the structural strength of the compressor air pipe, reduce the amplitude of the compressor air pipe, thereby reducing the abnormal noise caused by vibration and the maximum stress value of the compressor air pipe, and avoiding damage to the compressor air pipe.

[0004] This utility model is achieved through the following technical solution: a compressor pipe, comprising a first pipe section, a second pipe section, and a third pipe section connected in sequence. The first pipe section is used for connection to the outside. The first pipe section includes a first vertical pipe section, a first horizontal pipe section, and a second vertical pipe section connected in sequence. The second pipe section includes a second horizontal pipe section and a third vertical pipe section connected in sequence. The second vertical pipe section is connected to the second horizontal pipe section. The first vertical pipe section, the second vertical pipe section, and the third vertical pipe section all extend in a vertical direction. The first horizontal pipe section and the second horizontal pipe section all extend in a horizontal direction. The third pipe section is used for connection to the compressor. The planes in which the first pipe section, the second pipe section, and the third pipe section are located are neither coplanar nor parallel.

[0005] Compared with the prior art, the compressor pipe provided by this utility model, through the structural design of alternating vertical and horizontal pipe sections in both the first and second pipe sections, and the three-dimensional layout design in which the planes of the first, second, and third pipe sections are neither coplanar nor parallel, can effectively enhance the structural strength of the compressor pipe and increase its natural vibration frequency. In particular, when resonance or excessive vibration occurs at a certain compressor speed, it can effectively reduce the amplitude of the compressor pipe, thereby reducing the abnormal noise caused by vibration and the maximum stress value of the compressor pipe, and avoiding damage to the compressor pipe.

[0006] Furthermore, the third pipe section includes a first curved pipe section and a fourth vertical pipe section extending in the vertical direction. The fourth vertical pipe section is connected to the third vertical pipe section through the first curved pipe section, and the direction of gas flow in the fourth vertical pipe section is parallel and opposite to that in the third vertical pipe section. Thus, the design of the curved pipe section helps to absorb and disperse the mechanical vibration energy and pressure pulsation energy generated by gas flow and compressor operation, reducing vibration and noise. In addition, the curved pipe section design also creates a natural support point in the vertical direction, making the compressor pipe more stable in the vertical direction and helping to reduce swaying and vibration during compressor operation.

[0007] Furthermore, the second pipe section also includes a second curved pipe section and a fifth vertical pipe section extending in a vertical direction. The fifth vertical pipe section is connected to the third vertical pipe section through the second curved pipe section. The gas flow direction in the fifth vertical pipe section is parallel to and opposite to that in the third vertical pipe section. The third pipe section includes an inclined pipe section extending in a straight line and a sixth vertical pipe section extending in a vertical direction. The sixth vertical pipe section is connected to the fifth vertical pipe section through the inclined pipe section. Thus, through the design of two vertical pipe sections and one inclined pipe section, the structural strength and stability of the third pipe section can be further improved, and the structural strength and stability of all three pipe sections of the compressor pipe are improved, thereby ensuring the overall structural strength and stability of the compressor pipe and further reducing the amplitude of the compressor pipe during compressor operation.

[0008] Furthermore, the third pipe section includes a helical pipe section and a seventh vertical pipe section extending in a vertical direction. The seventh vertical pipe section is connected to the third vertical pipe section via the helical pipe section, and the gas flow directions of the seventh vertical pipe section and the third vertical pipe section are parallel and opposite. Therefore, the design of the helical pipe section significantly improves the structural strength and stability of the third pipe section. Moreover, the compressor pipes are mutually supported by the helical pipe section, the first pipe section, and the second pipe section, making them less prone to deformation and exhibiting good stability. This significantly reduces the amplitude of the compressor pipes during compressor operation.

[0009] Furthermore, the spiral tube segment includes several curved sections and vertical sections extending in a vertical direction. The vertical sections and curved sections are alternately connected to form the spiral tube segment, and the third and seventh vertical tube segments are both connected to the curved sections. Thus, through the design of the curved and vertical sections, the spiral tube segment can better absorb and mitigate mechanical vibration energy and pressure pulsation energy, thereby significantly improving the structural strength and stability of the third tube segment and the compressor pipe as a whole.

[0010] Furthermore, the diameter of the compressor pipe is D, the length of each pipe segment extending horizontally is L1≤20D, and the length of each pipe segment extending vertically is L2≤20D. Thus, by limiting the upper limits of the lengths of the horizontal and vertical pipe segments, on the one hand, the stress borne by each pipe segment is relatively uniform, thereby reducing the risk of stress concentration; on the other hand, the natural frequency of each pipe segment is increased, giving each pipe segment higher vibration resistance and making it less prone to matching the vibration frequency of the compressor.

[0011] Furthermore, both the first and second pipe sections include bent pipe sections, and the first horizontal pipe section, the first vertical pipe section, the second vertical pipe section, the second horizontal pipe section, and the third vertical pipe section are all connected by the bent pipe sections. Thus, the bent pipe sections allow for a smooth connection between the horizontal and vertical pipe sections, and also disperse and reduce the impact of vibration on the compressor's piping.

[0012] Furthermore, the first, second, and third pipe sections are integrated as a single unit. This integration of multiple pipe sections into a single structure makes the compressor piping more structurally stable, better able to withstand the vibrations generated by the compressor, reduces the number of connection points between pipe sections, and effectively reduces the transmission of vibration between pipe sections, thereby minimizing damage caused by vibration.

[0013] This utility model also provides an outdoor unit for an air conditioner, including a compressor and a compressor pipe as described above, wherein the compressor has an interface and the compressor pipe is connected to the interface.

[0014] This utility model also provides an air conditioner, including an indoor unit and an outdoor unit as described above, wherein the indoor unit is connected to the outdoor unit.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Example 1

[0025] Please see Figure 1 and Figure 2 This embodiment provides a compressor pipe for use in compressor exhaust or intake. The compressor pipe includes a first pipe section 10, a second pipe section 20, and a third pipe section 30 connected in sequence. The first pipe section 10 is used for connection to the outside and includes a first vertical pipe section 11, a first horizontal pipe section 12, and a second vertical pipe section 13 connected in sequence. The second pipe section 20 includes a second horizontal pipe section 21 and a third vertical pipe section 22 connected in sequence. The second vertical pipe section 13 is connected to the second horizontal pipe section 21. The first vertical pipe section 11, the second vertical pipe section 13, and the third vertical pipe section 22 all extend in a vertical direction, and the first horizontal pipe section 12 and the second horizontal pipe section 21 all extend in a horizontal direction. The third pipe section 30 is used for connection to the compressor. The planes in which the first pipe section 10, the second pipe section 20, and the third pipe section 30 are located are neither coplanar nor parallel.

[0026] Therefore, by adopting a structural design in which both the first pipe section 10 and the second pipe section 20 are connected by alternating vertical and horizontal pipe sections, and by adopting a three-dimensional layout design in which the planes of the first pipe section 10, the second pipe section 20 and the third pipe section 30 are neither coplanar nor parallel, the structural strength of the compressor pipe can be effectively enhanced, the natural vibration frequency of the compressor pipe can be increased, especially when resonance or excessive vibration is caused by a certain speed of the compressor, the amplitude of the compressor pipe can be effectively reduced, thereby reducing the abnormal noise caused by vibration and the maximum stress value of the compressor pipe, and avoiding damage to the compressor pipe.

[0027] In this embodiment, the third pipe section 30 includes a first curved pipe section 31 and a fourth vertical pipe section 32 extending in the vertical direction. The fourth vertical pipe section 32 is connected to the third vertical pipe section 22 through the first curved pipe section 31. The direction of gas flow in the fourth vertical pipe section 32 is parallel and opposite to that in the third vertical pipe section 22. Thus, the curved pipe section design helps to absorb and disperse the mechanical vibration energy and pressure pulsation energy generated by gas flow and compressor operation, reducing vibration and noise. Furthermore, the curved pipe section design also creates a natural support point in the vertical direction, making the compressor pipe more stable in the vertical direction and helping to reduce swaying and vibration during compressor operation.

[0028] In this embodiment, the diameter of the compressor pipe is D, and the length L1 of each horizontally extending pipe segment is ≤20D. Specifically, the length L1 of each of the first horizontal pipe segment 12 and the second horizontal pipe segment 21 is ≤20D. Preferably, L1 is ≤10D. In this embodiment, the length L2 of each vertically extending pipe segment is ≤20D. Specifically, the length L2 of each of the first vertical pipe segment 11, the second vertical pipe segment 13, the third vertical pipe segment 22, and the fourth vertical pipe segment 32 is ≤20D. Preferably, L2 is ≤10D. Thus, by limiting the upper limit of the length of the horizontal and vertical pipe segments, on the one hand, the stress borne by each pipe segment is relatively uniform, thereby reducing the risk of stress concentration; on the other hand, the natural frequency of each pipe segment is increased, giving each pipe segment higher vibration resistance and making it less likely to match the vibration frequency of the compressor.

[0029] In this embodiment, both the first pipe segment 10 and the second pipe segment 20 include a bent pipe segment 40, and the first vertical pipe segment 11, the first horizontal pipe segment 12, the second vertical pipe segment 13, the second horizontal pipe segment 21, and the third vertical pipe segment 22 are all connected by the bent pipe segment 40. Thus, the bent pipe segment allows for a smooth connection between the horizontal and vertical pipe segments, and it also helps to disperse and reduce the impact of vibration on the compressor's air pipes.

[0030] In this embodiment, the first pipe segment 10, the second pipe segment 20, and the third pipe segment 30 are integrated as a single unit. This integration of multiple pipe segments into a single structure makes the compressor piping more structurally stable, better able to withstand vibrations generated by the compressor, reduces the number of connection points between pipe segments, and effectively reduces the transmission of vibration between pipe segments, thereby minimizing damage caused by vibration.

[0031] In this embodiment, the plane where the first pipe segment 10 is located is the first plane, the plane where the second pipe segment 20 is located is the second plane, and the plane where the third pipe segment 30 is located is the third plane. The first plane, the second plane, and the third plane are projected onto a horizontal plane. The angle θ1 between the first plane and the second plane is 15°≤θ1≤165°; the angle θ2 between the first plane and the third plane is 15°≤θ2≤165°; and the angle θ3 between the second plane and the third plane is 15°≤θ3≤165°.

[0032] Example 2

[0033] Please see Figure 3 and Figure 4 The compressor pipe provided in this embodiment is basically the same as that in embodiment one. The difference is that the second pipe section 20 also includes a second curved pipe section 23 and a fifth vertical pipe section 24 extending in the vertical direction. The fifth vertical pipe section 24 is connected to the third vertical pipe section 22 through the second curved pipe section 23. The gas flow direction in the fifth vertical pipe section 24 is parallel and opposite to that in the third vertical pipe section 22. The third pipe section includes an inclined pipe section 33 extending in a straight line and a sixth vertical pipe section 34 extending in the vertical direction. The sixth vertical pipe section 34 is connected to the fifth vertical pipe section 24 through the inclined pipe section 33.

[0034] Therefore, by designing two vertical pipe sections and one inclined pipe section, the structural strength and stability of the third pipe section 30 can be further improved, and the structural strength and stability of the first pipe section 10, the second pipe section 20 and the third pipe section 30 are all improved, further enhancing the overall structural strength and stability of the compressor pipe, thereby further reducing the amplitude of the compressor pipe during compressor operation.

[0035] In this embodiment, the lengths L2 of the fifth vertical pipe segment 24 and the sixth vertical pipe segment 34 are each ≤ 20D. Preferably, L2 ≤ 10D.

[0036] Example 3

[0037] Please see Figure 5 and Figure 6The compressor pipe provided in this embodiment is basically the same as that in embodiment one. The difference is that the third pipe section 30 includes a spiral pipe section 35 and a seventh vertical pipe section 36 extending in the vertical direction. The seventh vertical pipe section 36 is connected to the third vertical pipe section 22 through the spiral pipe section 35. The gas flow directions of the seventh vertical pipe section 36 and the third vertical pipe section 22 are parallel and opposite.

[0038] Therefore, the design of the spiral tube section can significantly improve the structural strength and stability of the third tube section 30. Furthermore, the compressor pipe is supported by the spiral tube section 30, the first tube section 10, and the second tube section 20, making it less prone to deformation and more stable. This can significantly reduce the amplitude of the compressor pipe during compressor operation.

[0039] Specifically, the spiral tube segment 30 includes several bends 351 and vertical sections 352 extending in a vertical direction. The bends 351 and vertical sections 352 are alternately connected to form the spiral tube segment. The third vertical tube segment 22 and the seventh vertical tube segment 36 are both connected to the bends 351. Thus, through the design of the bends 351 and vertical sections 352, the spiral tube segment 35 better absorbs and mitigates mechanical vibration energy and pressure pulsation energy, thereby significantly improving the structural strength and stability of the third tube segment 30 and the compressor pipe as a whole.

[0040] In this embodiment, there are three bends 351 and two vertical sections 352, which are alternately connected to form a spiral tube segment. Of course, in other alternative embodiments, the number of bends 351 is not limited to three and can be more than three, and the number of vertical sections 352 is not limited to two and can be more than two, thereby forming a multi-turn spiral tube segment, thus improving the structural strength and stability of the compressor pipe.

[0041] For example, taking the compressor pipe described in Embodiment 3 as an example, the lengths of the first vertical pipe segment, the first horizontal pipe segment, and the second vertical pipe segment in the first pipe section are all 6D (D is the diameter of the compressor pipe), the lengths of the second horizontal pipe segment and the third vertical pipe segment in the second pipe section are all 6D, the total length of the spiral pipe segment is 10D (including the length of the bend), the width of the spiral pipe segment is 4D, and the pitch is 0.5D. Each segment of this compressor pipe is relatively short and has good stability. The entire pipe is supported by the spiral pipe segment, the horizontal pipe segment, and the vertical pipe segment, making it less prone to deformation. This significantly reduces the amplitude of the compressor pipe vibration caused by the compressor, thereby reducing abnormal noise from the air conditioner caused by vibration and the maximum stress value of the compressor pipe, thus preventing damage to the compressor pipe.
