Description

Technical Field

[0001] This invention relates to the field of refrigerator compressor vibration reduction technology, and more particularly to a compressor vibration reduction mechanism and a refrigerator. Background Technology

[0002] As an indispensable appliance in modern households, the refrigerator's core component—the compressor—directly affects its cooling efficiency, lifespan, and operating noise. However, compressors inevitably generate vibrations during operation. If these vibrations are not effectively controlled, they will not only accelerate the wear and tear on the compressor's mechanical parts and shorten its lifespan, but will also be transmitted to the surrounding environment through the refrigerator body, causing noise pollution and affecting the user experience. Therefore, the research and application of refrigerator compressor vibration reduction technology is particularly important.

[0003] Refrigerator compressor vibration mainly originates from unbalanced forces in its internal mechanical moving parts, air column resonance, and electromagnetic forces. This vibrational energy is continuously generated during compressor operation and transmitted through the compressor body to the refrigerator casing, and then diffuses into the surrounding environment. Prolonged vibration can not only cause loosening and accelerated wear of internal compressor parts, but may also lead to malfunctions such as loose pipe connections and refrigerant leaks, seriously affecting the refrigerator's stability and reliability.

[0004] To address compressor vibration issues, traditional methods primarily employ rigid mounting or simple rubber pads for vibration damping. Rigid mounting uses bolts to tightly connect the compressor to the refrigerator body, which, while limiting compressor displacement to some extent, cannot effectively absorb vibration energy. In fact, vibration transmission may cause resonance within the refrigerator body, exacerbating noise problems. Simple rubber pads utilize the elastic properties of rubber to absorb some vibration energy, but their damping effect is limited by factors such as the rubber material, thickness, and shape, making it difficult to meet the demands for high-precision, high-stability vibration damping.

[0005] Secondly, the rubber pads cannot completely isolate the compressor's vibration from the base plate, causing the refrigerator to make noise and vibrate when the compressor is running. When the vibration of the compressor exceeds the range that the rubber pads can withstand, the vibration is transmitted down the rubber pads to the base plate, and the vibration and noise will increase further. As a rotating machine, the compressor vibrates not only linearly but also torsionally, and the rubber pads cannot effectively dampen all of these vibrations.

[0006] Therefore, this application proposes a compressor vibration damping mechanism and a refrigerator. Summary of the Invention

[0007] The purpose of this invention is to solve the above-mentioned technical problems by proposing a compressor vibration damping mechanism and a refrigerator.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A compressor vibration damping mechanism includes a compressor and a bottom support, and further includes four sets of vibration damping structures for supporting the support. Each vibration damping structure includes a mounting cylinder and a support member located inside it. The mounting cylinder is provided with an elastic part, and a threaded tube that abuts against the support member is provided inside the elastic part. A screw connected to the support is provided inside the threaded tube. A plurality of first vibration damping parts are fixed on the outer wall of the threaded tube, and a second vibration damping part is provided inside the mounting cylinder. The second vibration damping part is divided into damping zones and vibration damping zones distributed vertically. When the compressor operates, causing the support to move the threaded tube up and down, the first damping part and the second damping part move relative to each other, and the second damping part deforms to varying degrees.

[0009] Preferably, an annular cover is installed at the upper end of the mounting cylinder, and the elastic part is installed in the middle of the annular cover and fastened to the annular cover; The elastic part is made of rubber.

[0010] Preferably, a support washer is fixed on the screw. When the screw is installed in place inside the threaded tube, the support washer abuts against the upper end of the threaded tube. The screw passes through the bracket, and a nut is threaded onto the screw. Tightening the nut fixes the bracket to the screw.

[0011] Preferably, a rubber pad is fixed to the bottom of the mounting cylinder, and a mounting block is fixed to the bottom of the rubber pad. The mounting block has multiple mounting holes.

[0012] Preferably, the mounting cylinder is provided with a detachable mounting ring, and the upper end of the second vibration damping part is fixed with a mounting plate, which is fixed to the bottom of the mounting ring.

[0013] Preferably, both the first and second vibration damping sections are arranged in the shape of a corrugated plate, the height of the first vibration damping section is smaller than the height of the second vibration damping section, and the wave crests and troughs on the first and second vibration damping sections correspond to each other.

[0014] Preferably, a connecting rod is fixed on the first vibration damping part, and the number of the connecting rods is at least two. The connecting rods are evenly distributed on the first vibration damping part, and the connecting rods are fixedly connected to the threaded pipe.

[0015] Preferably, the support includes a porous support block that slides inside the mounting cylinder, a spring is fixed to the bottom of the porous support block, the lower end of the spring is fixed to the inner bottom of the mounting cylinder, and the lower end of the threaded tube abuts against the upper end of the porous support block.

[0016] Preferably, the mounting cylinder contains lubricating oil, and the level of the lubricating oil is located above the porous support block.

[0017] The present invention also discloses a refrigerator, which includes a compressor vibration damping mechanism.

[0018] Compared with the prior art, the beneficial effects of this invention are as follows: 1. More comprehensive vibration reduction dimensions, covering multiple types of vibration; breaking through the limitations of traditional vibration reduction structures that only target "linear vibration", through the wave structure of the first and second vibration reduction parts, it can effectively control both "vertical vibration" and "horizontal / torsional vibration" at the same time, adapting to the complex vibration scenarios in the actual operation of the compressor, reducing the overall shaking and noise transmission of the refrigerator.

[0019] 2. By utilizing the partitioned design of the second vibration reduction section, consisting of a "damping zone (high stiffness) + vibration reduction zone (low stiffness)," a progressive vibration reduction logic of "graded buffering - strong limiting" is formed: small-amplitude vibrations are flexibly absorbed by the vibration reduction zone, while large-amplitude vibrations are rigidly limited by the damping zone. This avoids both "insufficient vibration reduction" and "structural damage caused by excessive deformation," while also suppressing upward rebound impacts and improving vibration reduction stability.

[0020] 3. The structure has high reliability and is suitable for long-term high-frequency vibration. It is made of stainless steel or elastic metal and has better fatigue resistance and aging resistance than traditional rubber pads. It can withstand the high-frequency vibration of the compressor for a long time without "elastic decay" or "breakage". In addition, the corrugated plate structure avoids structural failure caused by local stress concentration by "deformation and stress dispersion", thus extending the service life of vibration damping components.

[0021] 4. As rotating machinery, compressors vibrate not only linearly but also torsionally. Traditional rubber feet cannot effectively dampen all types of vibration. This invention, through the synergistic effect of multiple damping structures, can effectively buffer and absorb various vibration types, including linear and torsional vibrations, providing more comprehensive vibration protection.

[0022] 5. The second vibration damping part is connected to the detachable mounting ring via a mounting plate, and the first vibration damping part is fixed to the threaded pipe via a connecting rod. If the vibration damping part is worn, it can be disassembled and replaced separately without replacing the entire vibration damping structure, thus reducing maintenance costs. At the same time, during installation, the position of the mounting ring (the position along the axial direction of the mounting cylinder can change the contact position of the first and second vibration damping parts) can be adjusted to adapt to the vibration parameters of different compressor models, thereby improving versatility.

[0023] In summary, this invention provides comprehensive vibration reduction, simultaneously controlling vertical, horizontal, and torsional vibrations, adapting to complex vibration scenarios of compressors, and effectively reducing refrigerator shaking and noise transmission. Relying on the hierarchical design of the damping zone and vibration reduction zone, small-amplitude vibrations are flexibly absorbed by the vibration reduction zone, while large-amplitude vibrations are rigidly limited by the damping zone, which can also suppress rebound and avoid insufficient vibration reduction or structural damage.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Reference Figures 1-7 A compressor vibration damping mechanism includes a compressor 1 and a bottom bracket 2. The bracket 2 is fixed to the bottom of the compressor 1 by bolts to support the compressor 1. The bracket 2 is provided with mounting holes for subsequent installation so as to fix the bracket 2.

[0028] It also includes four sets of shock-absorbing structures for supporting bracket 2, each corresponding to one of the four mounting holes on bracket 2. The shock-absorbing structure includes a mounting cylinder 5 and a support member located inside it. The mounting cylinder 5 is provided with an elastic part 7, and the elastic part 7 is provided with a threaded tube 15 that abuts against the support member. The inner wall of the threaded tube 15 is threaded, and the outer side is a smooth cylindrical shape. The upper end of the mounting cylinder 5 is provided with an annular cover 6. The annular cover 6 can be connected to the mounting cylinder 5 by means of threads or by means of bolts. A sealing ring is provided at the connection between the two.

[0029] The elastic part 7 is installed in the middle of the annular cover 6 and fastened to the annular cover 6. The elastic part 7 is made of rubber. The elastic part 7 is annular in shape and has an I-shaped cross section. When the elastic part 7 is installed on the annular cover 6, it can fasten to the side wall of the annular cover 6. The elastic part 7 slides against the outer wall of the threaded tube 15. In order to ensure sealing, a sealing ring can be provided between the two.

[0030] The support includes a porous support block 11 that slides inside the mounting cylinder 5. The porous support block 11 is made of rubber. A spring 12 is fixed to the bottom of the porous support block 11. The lower end of the spring 12 is fixed to the inner bottom of the mounting cylinder 5. The lower end of the threaded tube 15 abuts against the upper end of the porous support block 11. Connecting rings are welded to both ends of the spring 12. The connecting rings are fixed to the bottom of the porous support block 11 and the inner bottom of the mounting cylinder 5 by bolts.

[0031] The mounting cylinder 5 contains lubricating oil, and the oil level is above the porous support block 11. The lubricating oil makes the porous support block 11 slide more smoothly in the mounting cylinder 5, reducing wear. At the same time, when the lubricating oil flows through the porous support block 11, it dampens the movement of the porous support block 11.

[0032] The threaded tube 15 is equipped with a screw 9 connected to the bracket 2. The screw 9 is threaded to the inner wall of the threaded tube 15. A support washer 8 is fixed on the screw 9. When the screw 9 is installed in place in the threaded tube 15, the support washer 8 abuts against the upper end of the threaded tube 15. The screw 9 passes through the bracket 2. A nut 10 is threaded on the screw 9. Tightening the nut 10 fixes the bracket 2 to the screw 9. The bottom of the bracket 2 abuts against the upper end of the support washer 8. The support washer 8 increases the contact area with the bracket 2, thereby providing stable support for the bracket 2.

[0033] When the compressor 1 operates, causing the bracket 2 to vibrate downwards, it will drive the screw 9 and the threaded tube 15 to move downwards, and the threaded tube 15 and the elastic part 7 will move relative to each other; since the elastic part 7 is made of rubber, it can buffer and dampen the threaded tube 15 in the horizontal direction.

[0034] The threaded tube 15 moves downward and the porous support block 11 moves downward, driving it to move downward. At this time, the spring 12 is compressed, and the force of vibration can be buffered by the porous support block 11 and the spring 12.

[0035] Multiple first damping parts 20 are fixed to the outer wall of the threaded pipe 15. A second damping part 14 is provided inside the mounting cylinder 5. The second damping part 14 is divided into damping zones 16 and damping zones 17 distributed vertically. The mounting cylinder 5 is provided with a detachable mounting ring 13. The mounting ring 13 is fixed to the inner wall of the mounting cylinder 5 from the outside using bolts. A sealing ring is provided at the connection. A mounting plate 18 is fixed to the upper end of the second damping part 14. The mounting plate 18 is fixed to the bottom of the mounting ring 13, thus realizing the fixed installation of the second damping part 14.

[0036] like Figure 6 As shown, both the first damping part 20 and the second damping part 14 are arranged in the shape of a wave plate. The materials of the first damping part 20 and the second damping part 14 are stainless steel or other metal materials, which can undergo a certain deformation and can also return to their original position. The height of the first damping part 20 is less than the height of the second damping part 14, and the crests and troughs on the first damping part 20 and the second damping part 14 correspond to each other.

[0037] In this configuration, a connecting rod 19 is fixed on the first vibration damping part 20. There are at least two connecting rods 19, which are evenly distributed on the first vibration damping part 20. With this configuration, the connecting rods 19 can provide stable support for the first vibration damping part 20. The connecting rods 19 are fixedly connected to the threaded pipe 15, and the ends of the connecting rods 19 are fixed to the threaded pipe 15 by welding or bolts.

[0038] When the compressor 1 operates, causing the bracket 2 to move the threaded tube 15 up and down, the first damping part 20 and the second damping part 14 move relative to each other, and the second damping part 14 deforms to different degrees. Since the damping area 16 is located at the upper end and close to the mounting plate 18, the lower damping area 17 is more prone to deformation than the upper damping area 16. When the first damping part 20 moves downward, the corresponding positions of the wave crests and troughs on the first damping part 20 and the second damping part 14 are misaligned. Since the first damping part 20 cannot move, it will squeeze the damping area 17 to move outward. However, as the relative movement of the first damping part 20 and the second damping part 14 increases, the resistance to driving the damping area 17 outward increases. The upper damping area 16 will also be driven to move outward. The resistance to the outward movement of the damping area 16 is large, which will limit the downward movement of the first damping part 20, thus preventing the damping area 17 from continuously opening outward. In other words, as the relative displacement increases, the deformation resistance of the damping zone 17 gradually increases, initially limiting the displacement; the damping zone 16 has high stiffness and its deformation resistance is much greater than that of the damping zone 17, strongly limiting the first damping part 20 from moving further downward and avoiding excessive vibration.

[0039] Since the damping zone 17 on the lower side of the second damping part 14 is not limited, and the second damping part 14 is made of elastic metal, when the threaded pipe 15 and the first damping part 20 vibrate horizontally, the damping zone 17 can buffer the vibration of the threaded pipe 15 and the first damping part 20 in multiple horizontal directions, thereby achieving vibration protection for the compressor 1.

[0040] When the first damping part 20 moves upward, the damping zone 16 is closer to the upper side, that is, closer to the mounting plate 18, and the greater the resistance to deformation. Therefore, compared with the downward movement of the first damping part 20, the upward movement of the first damping part 20 is more difficult, and the upward movement is hindered. In other words, the upward movement resistance of the first damping part 20 is significantly greater than the initial resistance when moving downward, which directly suppresses the upward rebound speed and amplitude and reduces bouncing vibration.

[0041] Thus, by setting up the damping zone 16 and the vibration reduction zone 17, the movement of the first vibration reduction part 20 is effectively restricted, thereby achieving a better vibration reduction effect.

[0042] The bottom of the mounting cylinder 5 is fixed with a rubber pad 4, and the mounting cylinder 5 is fixed to the rubber pad 4 by glue or bolts; the bottom of the rubber pad 4 is fixed with a mounting block 3, and the rubber pad 4 is fixed to the mounting block 3 by bolts or screws; the mounting block 3 has multiple mounting holes, and bolts can be used to pass through the mounting holes to install the mounting block 3 inside the refrigerator, thereby realizing the installation of the compressor 1.

[0043] The present invention also discloses a refrigerator, which includes a compressor vibration damping mechanism.

[0044] In actual use, the first step is to install the shock-absorbing structure by fixing the mounting block 3 inside the refrigerator with bolts, removing the annular top cover 6, fixing the mounting ring 13 inside the mounting cylinder 5 with bolts, and then adding an appropriate amount of lubricating oil to the mounting cylinder 5. The elastic part 7 is installed on the annular cover 6, and the threaded tube 15 passes through the bottom of the elastic part 7 and is installed on the elastic part 7; then the threaded tube 15 is inserted into the mounting ring 13, and the first damping part 20 on the threaded tube 15 is offset from the second damping part 14 at the bottom of the mounting ring 13. Then the threaded tube 15 is held and fixed to the annular cover 6, so that it is fixed to the mounting cylinder 5. The annular cover 6 is fixed to the mounting cylinder 5 by bolts, or by rotation and threaded connection. Holding the threaded tube 15 is to limit its position and ensure that the first damping part 20 and the second damping part 14 are always in an offset state. Move the threaded tube 15 downwards until it abuts against the porous support block 11; at this point, the positions of the first damping part 20 and the second damping part 14 correspond, i.e., the crests face each other and the troughs face each other; then rotate the threaded tube 15, which in turn rotates the connecting rod 19 and the first damping part 20, causing them to overlap. Figure 6 As shown; Connect the screw 9 to the threaded tube 15 until the mounting plate 18 abuts against the threaded tube 15. During this process, ensure that the threaded tube 15 no longer rotates. This completes the assembly of the shock-absorbing structure.

[0045] Next, the bracket 2 is placed on the screw 9 and abuts against the support washer 8. The nut 10 is rotated on the screw 9 and tightened until the bracket 2 is fixed on the screw 9, thus completing the installation of the compressor 1.

[0046] Since the screw 9 is fixed to the threaded tube 15 as a whole, and the screw 9 is fixed on the bracket 2, the screw 9 will limit the threaded tube 15, making it difficult for the threaded tube 15 to rotate after installation, thereby limiting the first damping part 20, making it difficult for it to move, and preventing it from being misaligned with the second damping part 14.

[0047] To ensure that the first damping part 20 and the second damping part 14 are not misaligned, two threaded holes can be machined on the mounting cylinder 5, and bolts with round ends can be sealed and installed in the threaded holes. After all the installation is completed, the bolts at this position are installed. The installed bolts are located on both sides of one of the second damping parts 14, so as to limit the first damping part 20.

[0048] When compressor 1 is working, the vibration it generates is transmitted to the bottom support 2, which in turn triggers a series of vibration damping actions. The specific working process is as follows: Initial vibration transmission: The vibration generated by the operation of compressor 1 causes support 2 to vibrate downwards, and support 2 drives screw 9 and threaded tube 15 to move downwards.

[0049] The elastic part 7 provides cushioning. When relative movement occurs between the threaded tube 15 and the elastic part 7, the elastic part 7 is made of rubber and has an annular shape and an I-shaped cross-section. It can buffer and dampen the threaded tube 15 in the horizontal direction and absorb some of the vibration energy.

[0050] The porous support block 11 and spring 12 act as a buffer. During the downward movement of the threaded tube 15, it contacts the porous support block 11 and drives it downward, at which point the spring 12 is compressed. The porous support block 11 is made of rubber and has a porous structure. Combined with the elasticity of the spring 12, it further buffers the force of vibration, reducing the impact of vibration on the compressor 1 and the overall structure. At the same time, the lubricating oil contained in the mounting cylinder 5 is positioned above the porous support block 11. When the porous support block 11 slides within the mounting cylinder 5, the lubricating oil makes its sliding smoother, reducing wear. Furthermore, the flow of the lubricating oil through the porous support block 11 dampens its movement, assisting in vibration reduction.

[0051] The first vibration damping unit 20 and the second vibration damping unit 14 work together to reduce vibration. The vibration damping mechanism moves up and down. When the support 2 drives the threaded tube 15 to vibrate downwards, the first damping part 20 and the second damping part 14 move relative to each other. The second damping part 14 is divided into a damping zone 16 and a damping zone 17 distributed vertically. The lower damping zone 17 (with lower stiffness) is more prone to deformation than the upper damping zone 16.

[0052] When the first damping part 20 moves downward, the corresponding positions of the wave crests and troughs on the first damping part 20 and the second damping part 14 are misaligned. Since the first damping part 20 cannot move, it will squeeze the damping area 17 to move outward. As the relative movement increases, the resistance driving the damping area 17 outward increases. The upper damping area 16 will also be driven to move outward, but the resistance of the damping area 16 to move outward is large, which will limit the downward movement of the first damping part 20 and prevent the damping area 17 from opening outward continuously.

[0053] When the first damping section 20 moves upward, the damping zone 16, being closer to the upper side (closer to the mounting plate 18), experiences greater resistance to deformation (higher stiffness). Compared to downward movement, upward movement faces greater resistance and is thus hindered. The damping zone 16 and the damping zone 17 create a progressive damping logic of "graded buffering - strong limiting," effectively restricting the movement of the first damping section 20 and achieving a better vibration damping effect.

[0054] By utilizing the partitioned design of the second vibration damping section 14, namely "damping zone 16 (high stiffness) and vibration damping zone 17 (low stiffness)," a progressive vibration damping logic of "graded buffering - strong limiting" is formed: small-amplitude vibrations are flexibly absorbed by the vibration damping zone 17, while large-amplitude vibrations are rigidly limited by the damping zone 16. This avoids both "insufficient vibration damping" and "structural damage caused by excessive deformation," while also suppressing upward rebound impacts and improving vibration damping stability.

[0055] The horizontal or torsional vibration generated during the operation of the compressor 1 is transmitted to the first damping part 20 through the threaded pipe 15, causing the first damping part 20 to generate a horizontal offset force.

[0056] The damping zone 17 of the second damping section 14 has no additional limit and the metal material has elastic restoring ability, which can adapt to deformation in multiple horizontal directions to offset the offset force of the first damping section 20. At the same time, the wave structure absorbs torsional vibration energy through "misalignment buffering", which fills the defect of traditional rubber pads in terms of insufficient horizontal / torsional vibration damping. The damping zone 17 can buffer the vibration of the threaded pipe 15 and the first damping section 20 in multiple horizontal directions, so as to achieve vibration damping protection for the compressor 1.

[0057] Through the above multi-stage and multi-method vibration reduction process, the vibration of compressor 1 during operation is effectively reduced, the stability of compressor 1 operation is improved, and the impact on the surrounding environment and other components is reduced.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
