Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to a compressor vibration damping device, an outdoor air conditioning unit, and an air conditioner. Background Technology

[0002] The vibration damping design of the compressor directly affects the noise level generated by the vibration of the outdoor unit of the air conditioner. Currently, vibration damping rubber pads are usually installed between the compressor and the chassis of the outdoor unit to reduce the compressor's own vibration and the transmission of vibration to the chassis, thereby reducing air conditioner noise and protecting the piping. As the requirements for vibration and noise in air conditioning products become more stringent, two-stage vibration isolation technology has begun to be applied in the field of compressor vibration isolation.

[0003] Existing vibration damping devices do not provide sufficient overall constraint on the compressor. During transportation, excessive compressor shaking can easily cause pipe breakage, as the top of the compressor is connected to the air conditioning piping, leading to air conditioner damage and increased equipment costs. While some compressors are transported with temporary fixing devices to reduce top-level shaking, these devices need to be removed during air conditioner installation, resulting in complex structures and inconvenient operation. Furthermore, single-stage vibration damping devices often rely on high stiffness to prevent excessive compressor movement during vibration, leading to a higher natural frequency that can cause resonant vibrations at low compressor operating frequencies. In contrast, multi-stage foot pads often have more upper foot pads than lower ones, leading to uneven stress on the lower foot pads, causing compressor tilting, unstable connections, and poor vibration damping. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a compressor vibration damping device, an outdoor air conditioning unit, and an air conditioner, which solves the problem of pipeline damage caused by excessive compressor shaking during transportation.

[0005] The present invention adopts the following technical solution.

[0006] The first aspect of this utility model discloses a compressor vibration damping device, applied to the vibration damping of the compressor inside the outdoor unit of an air conditioner, comprising: a fixed bracket, an adapter plate, primary vibration damping pads, and secondary vibration damping pads.

[0007] The lower end of the fixed bracket is connected to the outdoor unit of the air conditioner, and the upper end is connected through multiple primary shock-absorbing pads and an adapter plate. The upper end of the adapter plate is connected to the upper part of the compressor through multiple secondary shock-absorbing pads.

[0008] The number of primary shock-absorbing pads is greater than or equal to the number of secondary shock-absorbing pads, and the total vertical stiffness of the primary shock-absorbing pads is greater than or equal to the total vertical stiffness of the secondary shock-absorbing pads.

[0009] Preferably, the total vertical stiffness of the primary shock-absorbing pads is equal to the number of primary shock-absorbing pads multiplied by the vertical stiffness of the primary shock-absorbing pads, and the total vertical stiffness of the secondary shock-absorbing pads is equal to the number of secondary shock-absorbing pads multiplied by the vertical stiffness of the secondary shock-absorbing pads.

[0010] Preferably, the fixed bracket includes: an upper mounting part, a support part, and a mounting plate. Multiple support parts are evenly arranged circumferentially at the bottom of the upper mounting part. One end of the support part is connected to the mounting plate, and the mounting plate is connected to the outdoor unit of the air conditioner through screw holes.

[0011] Preferably, the upper mounting part is provided with a plurality of through holes I evenly distributed around the circumference, and the adapter plate is provided with through holes II corresponding to the positions of through holes I. The lower positioning bolts pass through through holes I, the primary shock-absorbing pads and through holes II in sequence, and are fixed by the lower nuts.

[0012] Preferably, both the upper mounting part and one side of the adapter plate have openings, and the arc-shaped buckle on the compressor is inserted into the opening and connected to the compressor receiver.

[0013] Preferably, the adapter plate is provided with a plurality of foot pad mounting holes evenly distributed around its circumference, and the foot pad mounting holes and the primary shock-absorbing foot pads are staggered.

[0014] Preferably, the compressor has a compressor mounting base on the upper outer periphery corresponding to the foot pad mounting hole. The upper positioning bolt passes through the foot pad mounting hole, the secondary shock-absorbing foot pad and the compressor mounting base in sequence, and is fixed by the upper nut.

[0015] The second aspect of this utility model discloses an outdoor unit for an air conditioner, comprising: a chassis and a compressor, and further comprising the compressor vibration damping device, wherein the compressor vibration damping device is disposed between the chassis and the compressor.

[0016] The third aspect of this utility model discloses an air conditioner, including the aforementioned outdoor unit.

[0017] The beneficial effect of this utility model is that, compared with the prior art,

[0018] This utility model connects the compressor shock absorption device to the upper part of the compressor, eliminating the need for additional temporary fixing devices, thereby improving the stability of the compressor and reducing the risk of pipeline damage caused by excessive compressor shaking during transportation. It also provides double shock absorption through primary and secondary shock absorption pads, which greatly improves the shock absorption effect, reduces compressor vibration noise, improves compressor stability, and further reduces the risk of pipeline damage caused by excessive shaking of the top of the compressor during transportation.

[0019] This invention features a secondary shock-absorbing foot pad with a primary shock-absorbing foot pad underneath for double shock absorption. The total vertical stiffness of the primary shock-absorbing foot pad is greater than or equal to that of the secondary shock-absorbing foot pad. This allows the natural frequency of the secondary shock-absorbing foot pad to be lower than that of a conventional single-stage shock-absorbing device, preventing excessive compressor displacement. This helps avoid resonance with the compressor's natural frequency during low-frequency operation, reducing compressor vibration during low-frequency operation and improving compressor stability during vibration. Furthermore, the number of primary shock-absorbing foot pads is greater than or equal to the number of secondary shock-absorbing foot pads, preventing uneven force distribution during compressor vibration that could cause compressor tilting and improving connection stability.

On the other hand, during compressor operation, it prevents the compressor, compressor receiver and the compressor vibration damping device from colliding and causing damage to the air conditioner, thereby improving the safety and reliability of the vibration damping process.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The embodiments described in this application are merely some embodiments of this utility model, not all embodiments. Based on the spirit of this utility model, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of this utility model.

[0029] like Figures 1-5 As shown, Embodiment 1 of this utility model discloses a compressor vibration damping device, mainly used for vibration damping of the compressor 3 inside the outdoor unit 1 of an air conditioner. The compressor vibration damping device includes: a fixed bracket 7, an adapter plate 13, primary vibration damping pads 18 and secondary vibration damping pads 19. The lower end of the fixed bracket 7 is connected to the outdoor unit 1 of the air conditioner, and the upper end is connected to the adapter plate 13 through multiple primary vibration damping pads 18. The upper end of the adapter plate 13 is connected to the compressor 3 through multiple secondary vibration damping pads 19.

[0030] The number of primary shock-absorbing pads 18 is greater than or equal to the number of secondary shock-absorbing pads 19, so that the total vertical stiffness K of the primary shock-absorbing pads is... m The total vertical stiffness K of the secondary shock-absorbing foot pad is greater than or equal to that of the secondary shock-absorbing foot pad. n .

[0031] The total vertical stiffness K of the primary shock-absorbing foot pad m The total vertical stiffness K of the secondary shock-absorbing pads is equal to the number of primary shock-absorbing pads (18) multiplied by the vertical stiffness K1 of the primary shock-absorbing pads. n It equals the number of secondary shock-absorbing foot pads 19 multiplied by the vertical stiffness K2 of the secondary shock-absorbing foot pads.

[0032] Specifically, the total vertical stiffness K of the primary shock-absorbing foot pad m It can be expressed by the following formula:

[0033] K m =m×K1

[0034] In the formula:

[0035] K mThe total vertical stiffness of the first-level shock-absorbing foot pad;

[0036] m represents the number of level 1 shock-absorbing foot pads;

[0037] K1 represents the vertical stiffness of the first-level shock-absorbing foot pad, obtained from the factory parameters.

[0038] Meanwhile, the total vertical stiffness K of the secondary shock-absorbing foot pads n It can be expressed by the following formula:

[0039] K n =n×K2

[0040] In the formula:

[0041] K n The total vertical stiffness of the secondary shock-absorbing foot pads;

[0042] n represents the number of secondary shock-absorbing foot pads;

[0043] K2 represents the vertical stiffness of the secondary shock-absorbing foot pads, obtained from factory parameters.

[0044] In a specific embodiment, when the compressor 3 vibrates, the vibration of the compressor 3 is damped by the secondary damping pads 19 and then transmitted to the adapter plate 13. The vibration of the adapter plate 13 is damped by the primary damping pads 18 and then transmitted to the fixed bracket 7, achieving double damping and significantly improving the damping effect. At the same time, because the primary damping pads 18 are below the secondary damping pads 19 for double damping and the total vertical stiffness K of the primary damping pads is... m The total vertical stiffness K of the secondary shock-absorbing foot pad is greater than or equal to that of the secondary shock-absorbing foot pad. n This allows the natural frequency of the secondary damping pads to be lower than that of conventional single-stage damping devices, which helps to avoid resonance with the compressor's natural frequency during low-frequency operation, effectively reducing the vibration of the compressor 3 during low-frequency operation and improving the stability of the compressor 3 during vibration. Moreover, the number of primary damping pads m is greater than or equal to the number of secondary damping pads n, which avoids uneven force distribution during compressor vibration that could cause the compressor to tilt, thus improving connection stability.

[0045] Preferably, but not limitingly, the internal structural dimensions and performance of the primary damping pad 18 and the secondary damping pad 19 may be the same or different.

The mounting plate 29 is connected to the chassis 2 on the outdoor unit 1 of the air conditioner through screw holes 30.

[0047] The upper mounting part 27 is provided with a plurality of through holes 25 evenly distributed around the circumference. The adapter plate 13 is provided with through holes 26 corresponding to the positions of the through holes 25. The lower positioning bolt column 22 passes through the through holes 25, the primary shock-absorbing pad 18 and the through holes 26 in sequence, and is fixed by the lower nut 21.

[0048] Both the upper mounting part 27 and the adapter plate 13 have openings 33 on one side. The arc-shaped buckle 31 on the compressor 3 is inserted into the opening 33 and connected to the compressor receiver 14. The arc-shaped buckle 31 is connected to the compressor 3 in the middle on the side near the compressor 3. The two sides of the arc-shaped buckle 31 and the compressor 3 are arc-shaped. The arc-shaped structure and the opening 33 are adapted to each other in shape and size and are inserted into the opening 33. The ends of the arc-shaped structure are connected to the two ends of multiple fixing rings 32. The compressor receiver 14 is fixed between the fixing rings 32 and the arc-shaped buckle 31.

[0049] It is understandable that the opening 33 and the arc-shaped buckle 31 are designed to improve the convenience, safety and stability of assembling the compressor 3, the compressor receiver 14 and the compressor vibration damping device, so that the compressor receiver 14 can be better adapted to the compressor vibration damping device. On the other hand, it is designed to prevent the compressor 3, the compressor receiver 14 and the compressor vibration damping device from colliding and causing damage to the air conditioner, thereby improving the safety and reliability of the vibration damping process.

[0050] The adapter plate 13 is provided with a plurality of foot pad mounting holes 24 evenly arranged around its circumference, and the foot pad mounting holes 24 and the primary shock-absorbing foot pad 18 are staggered.

[0051] The compressor 3 has a compressor mounting base 17 on the upper outer periphery corresponding to the foot pad mounting hole 24. The upper positioning bolt 20 passes through the foot pad mounting hole 24, the secondary shock-absorbing foot pad 19 and the compressor mounting base 17 in sequence, and is fixed by the upper nut 23.

[0052] Both the primary vibration damping pad 18 and the secondary vibration damping pad 19 have a through hole structure in the middle, which is used for the lower positioning bolt column 22 and the upper positioning bolt column 20 to pass through, respectively.

[0053] Preferably, but not limitingly, the lower end of the upper positioning bolt post 20 can be riveted to the adapter plate 13, the lower end of the lower positioning bolt post 22 can be riveted to the upper mounting part 27, the fixing bracket 7 can be made of structural steel with a thickness of 3-5mm, the adapter plate 13 can be made of structural steel with a thickness of 3-5mm, and the primary and secondary shock-absorbing pads can be made of rubber with a hardness range of 35-65 Shore hardness.

[0054] like Figure 1 and Figure 2 As shown, Embodiment 2 of this utility model discloses an outdoor unit for an air conditioner, including the aforementioned compressor vibration damping device;

[0055] The outdoor unit 1 of the air conditioner also includes: a chassis 2, a compressor 3, a front panel 5, a top plate 6, a four-way valve 9, and a gas-liquid separator 10. One side of the chassis 2 is connected to the front panel 5. The front panel 5 is provided with an air outlet grille 4 and its upper side is connected to the top plate 6. The compressor 3 is assembled inside the outdoor unit 1 through a compressor shock absorption device. The mounting plate 29 on the fixed bracket 7 is connected to the chassis 2 through screw holes 30. The compressor 3 is provided with a compressor exhaust pipe 16 at the top.

The compressor liquid receiver 14 is provided with a compressor suction pipe 15 at the top. The compressor suction pipe 15 is connected to the gas-liquid separator 10 through a suction pipe assembly 8.

[0056] Embodiment 3 of this utility model discloses an air conditioner, including the aforementioned outdoor unit.

[0057] The beneficial effect of this utility model is that, compared with the prior art,

[0058] This utility model improves the stability of the compressor by connecting the compressor shock absorption device to the upper part of the compressor without the need for additional temporary fixing devices. It reduces the risk of pipeline damage caused by excessive compressor shaking during transportation. Furthermore, it provides double shock absorption through primary and secondary shock absorption pads, which significantly improves the shock absorption effect, reduces compressor vibration noise, enhances compressor stability, and further reduces the risk of pipeline damage caused by excessive shaking of the top of the compressor during transportation.

[0059] This invention features a secondary shock-absorbing foot pad with a primary shock-absorbing foot pad underneath for double shock absorption. The total vertical stiffness of the primary shock-absorbing foot pad is greater than or equal to that of the secondary shock-absorbing foot pad. This allows the natural frequency of the secondary shock-absorbing foot pad to be lower than that of a conventional single-stage shock-absorbing device, preventing excessive compressor displacement. This helps avoid resonance with the compressor's natural frequency during low-frequency operation, reducing compressor vibration during low-frequency operation and improving compressor stability during vibration. Furthermore, the number of primary shock-absorbing foot pads is greater than or equal to the number of secondary shock-absorbing foot pads, preventing uneven force distribution during compressor vibration that could cause compressor tilting and improving connection stability.

[0060] The opening and arc-shaped buckle of this utility model are designed to improve the convenience and safety of assembling the compressor vibration damping device and the compressor, and to better adapt the compressor receiver to the compressor vibration damping device.
