Description

Technical Field

[0001] This invention relates to the field of compressor technology, and more particularly to a refrigerator compressor and its mounting base. Background Technology

[0002] Refrigerators are essential household appliances in daily life, and the compressor, as the "heart" of the refrigerator, directly affects the overall cooling effect, lifespan, and user experience.

[0003] Existing Chinese patent CN103542676B discloses a refrigerator and its compressor base plate. The compressor base plate is provided with a first compressor mounting assembly for mounting a first compressor and a second compressor mounting assembly for mounting a second compressor. The first and second compressor mounting assemblies are arranged at intervals. The first compressor mounting assembly includes multiple first bosses and a first base plate reinforcing structure connected to the multiple first bosses. The second compressor mounting assembly includes multiple second bosses and a second base plate reinforcing structure connected to the multiple second bosses. According to the refrigerator compressor base plate of the present invention, multiple compressors can be placed on the compressor base plate, and the compressor base plate has high structural strength, allowing multiple compressors to be stably placed on the compressor base plate.

[0004] Currently, existing refrigerator compressors suffer from the following main technical defects during installation and operation:

[0005] 1. The vibration and noise reduction effects are poor, posing a safety hazard.

[0006] During prolonged high-frequency operation, compressors inevitably generate severe mechanical vibrations and noise. Most existing refrigerator compressors are directly fixed to the mounting plate at the bottom of the refrigerator using simple rubber washers and bolts. This traditional rigid or semi-rigid connection structure has a short shock-absorbing stroke and often only absorbs a portion of high-frequency vibrations. Furthermore, with prolonged use, the rubber washers are prone to aging and hardening, leading to a significant reduction in shock absorption. This not only generates continuous low-frequency noise pollution, affecting users' rest, but may also cause resonance or even rupture of the refrigerator's internal refrigerant piping, posing certain safety hazards.

[0007] 2. Poor heat dissipation efficiency and additional energy consumption.

[0008] Compressors generate a significant amount of heat during operation. If this heat cannot be dissipated effectively and promptly, the compressor's casing and internal temperature will become excessively high, reducing its efficiency, increasing power consumption, and in severe cases, triggering overheat protection shutdown or burning out the motor. Currently, conventional refrigerator compressors rely heavily on natural convection for heat dissipation, resulting in extremely low efficiency. While some high-end refrigerators are equipped with a separate electric cooling fan next to the compressor, this not only increases energy consumption and production costs but also requires complex power supply wiring, increasing the likelihood of future maintenance failures. Existing technologies rarely offer energy-saving designs that can convert the compressor's harmful vibration energy into beneficial heat dissipation energy.

[0009] 3. Installation and disassembly are cumbersome, resulting in low production and maintenance efficiency.

[0010] In existing technologies, compressor installation and positioning typically involves drilling and locking multiple sets of bolts and nuts. This traditional installation method is cumbersome, time-consuming, and labor-intensive. During factory assembly or after-sales maintenance and replacement, operators need to use tools to manually align and tighten the bolts one by one in a confined space. This not only makes it difficult to ensure even force distribution but also significantly reduces production assembly efficiency and maintenance convenience.

[0011] In summary, designing a refrigerator compressor mounting base that can provide long-stroke, high-efficiency shock absorption, cleverly recover and utilize vibration mechanical energy for dual self-generated airflow cooling (pure physical energy saving), and also has convenient automatic clamping and fixing functions has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0012] To achieve the above objectives, the present invention adopts the following technical solution: a refrigerator compressor and a mounting base, comprising: a mounting base, wherein vertical rods are fixedly mounted on the top of the mounting base near its perimeter, limiting blocks are fixedly mounted on the top of the multiple vertical rods, springs are movably sleeved on the outer surface of the multiple limiting blocks, the bottoms of the multiple springs are fixedly mounted on the top of the mounting base, a support plate is movably sleeved on the outer surface of the multiple mounting bases near its top, a placement plate is fixedly mounted on the top of the support plate, the tops of the multiple springs are fixedly mounted on the outer surface of the support plate, a linkage bar is fixedly mounted on one side of the outer surface of the support plate, multiple push rods are fixedly mounted on the bottom of the linkage bar, and a compression plug is fixedly mounted on the bottom end of the multiple push rods.

[0013] The technical effect of adopting the above-mentioned further solution is that the refrigerator compressor will vibrate when it is running. Springs are set around the tray. When the refrigerator compressor on the tray vibrates, the tray will move vertically back and forth on the outer surface of multiple vertical rods, thereby achieving shock absorption. Shock absorption can reduce the noise of the compressor vibration when it is working.

[0014] In a preferred embodiment, a plurality of air cylinders are fixedly installed on one side of the mounting base, and the plurality of compression plugs are slidably connected to the inner wall of the plurality of air cylinders.

[0015] The technical effect of adopting the above-mentioned further solution is that when the pallet vibrates, it will also drive the linkage bar to move up and down repeatedly. At this time, the linkage bar pushes the extrusion plug to move up and down repeatedly on the inner wall of the air cylinder through the push rod, similar to the principle of injection. After the gas is squeezed out inside the air cylinder, it is blown to the bottom of the refrigerator compressor through the air pipe.

[0016] In a preferred embodiment, each of the plurality of air cylinders has an air pipe fixedly installed at its bottom, and the end of the plurality of air pipes away from the plurality of air cylinders is located on the side parallel to the placement plate.

[0017] The technical effect of adopting the above-mentioned further solution is that after the gas is squeezed out inside the gas cylinder, it is blown to the bottom of the refrigerator compressor through the gas pipe to dissipate heat, which can improve the heat dissipation efficiency of the refrigerator compressor during operation.

[0018] In a preferred embodiment, a cylinder is fixedly installed on the top of the pallet, a movable plate is fixedly installed at the output end of the cylinder, and two long rods are fixedly installed on the top of the pallet.

[0019] The technical effect of adopting the above-mentioned further solution is as follows: the cylinder is started by an external power source, and the cylinder pushes the moving plate to slide laterally on the outer surface of the long rod. At this time, the moving plate drives the moving strip to move laterally. At this time, the moving strip moves towards the fixed strip inside the long hole. The two long rods limit the movement of the moving plate, making the movement more stable.

[0020] In a preferred embodiment, the movable plate is slidably connected to the outer surfaces of the two long rods, the top of the placement plate has an elongated hole, and a movable strip is fixedly installed on the top of the movable plate.

[0021] The technical effect of adopting the above-mentioned further solution is that the moving strip moves towards the fixed strip inside the elongated hole, and the moving strip and the fixed strip can clamp and fix the compressor inside the refrigerator. At this time, the refrigerator compressor is installed on the upper surface of the elongated hole.

[0022] In a preferred embodiment, the movable strip passes through the interior of the elongated hole, and a fixing strip is fixedly installed on the top of the placement plate, the fixing strip being parallel to the movable strip.

[0023] The technical effect of adopting the above-mentioned further solution is that the parallelism between the fixed strip and the moving strip makes the clamping of the compressor more stable.

[0024] In a preferred embodiment, mounting screws are threaded into the surface of the mounting base near its perimeter, and a linkage bar is fixedly installed on one side of the support plate.

[0025] The technical advantage of adopting the above-mentioned further solution is that the mounting screws can install the entire device inside the refrigerator.

[0026] In a preferred embodiment, a rack is fixedly installed on the top of the second linkage bar, and a vertical bar is fixedly installed on one side of the mounting base, with a rotating rod movably embedded inside the vertical bar.

[0027] The technical effect of adopting the above-mentioned further solution is that when the pallet moves vertically back and forth on the outer surface of the vertical rod, the rack can be driven to move vertically back and forth through the second linkage.

[0028] In a preferred embodiment, a gear is fixedly mounted on one end of the rotating rod, and a fan is fixedly mounted on the other end of the rotating rod. The gear is meshed with the outer surface of the rack.

[0029] The technical effect of adopting the above-mentioned further solution is that the outer surfaces of the rack and pinion mesh with each other, causing the gear to rotate. When the gear rotates clockwise, it drives the fan to rotate through the rotating rod, which will blow out air. The airflow is horizontal along the upper surface of the placement plate, which can dissipate heat from the bottom of the refrigerator compressor when it is running.

[0030] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0031] 1. In this embodiment of the invention, when the pallet vibrates, it will also drive the linkage bar to move up and down repeatedly. At this time, the linkage bar pushes the extrusion plug to move up and down repeatedly on the inner wall of the air cylinder through the push rod, similar to the principle of injection. After the gas is squeezed out inside the air cylinder, it is blown to the bottom of the refrigerator compressor through the air pipe to dissipate heat. The dual air blowing heat dissipation can improve the heat dissipation efficiency of the refrigerator compressor during operation.

[0032] 2. In this embodiment of the invention, the refrigerator compressor is installed above the placement plate. After the refrigerator compressor is placed above the placement plate, the cylinder is started by an external power source. The cylinder pushes the moving plate to slide laterally on the outer surface of the long rod. At this time, the moving plate drives the moving strip to move laterally. At this time, the moving strip moves towards the fixed strip inside the long hole. The moving strip and the fixed strip can clamp and fix the compressor inside the refrigerator. At this time, the refrigerator compressor is installed on the upper surface of the long hole. When the refrigerator compressor is running, it will vibrate. Springs are set around the support plate. When the refrigerator compressor on the placement plate vibrates, the support plate will move vertically back and forth on the outer surface of multiple vertical rods, thereby achieving shock absorption. Shock absorption can reduce the noise of the compressor vibration during operation.

[0033] 3. In this embodiment of the invention, when the tray moves vertically back and forth on the outer surface of the vertical rod, the rack can be driven to move vertically back and forth through the linkage bar two. The rack meshes with the outer surface of the gear, thereby causing the gear to rotate. When the gear rotates clockwise, it drives the fan to rotate through the rotating rod, which will blow out air. The airflow is horizontal along the upper surface of the placement plate, which can dissipate heat from the bottom of the refrigerator compressor when it is running. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figures 1 to 6 This embodiment provides a technical solution: a refrigerator compressor and mounting base, including: a mounting base 101, with vertical rods 102 fixedly mounted on the top of the mounting base 101 near its periphery, limiting blocks 104 fixedly mounted on the top of the multiple vertical rods 102, springs 103 movably sleeved on the outer surface of the multiple limiting blocks 104, the bottom of the multiple springs 103 fixedly mounted on the top of the mounting base 101, a support plate 124 movably sleeved on the outer surface of the multiple mounting bases 101 near its top, a placement plate 105 fixedly mounted on the top of the support plate 124, the tops of the multiple springs 103 fixedly mounted on the outer surface of the support plate 124, a linkage bar 116 fixedly mounted on one side of the outer surface of the support plate 124, multiple push rods 115 fixedly mounted on the bottom of the linkage bar 116, and a compression plug 114 fixedly mounted on the bottom end of the multiple push rods 115.

[0044] When in use, the refrigerator compressor will vibrate during operation. Springs 103 are provided around the tray 124. When the refrigerator compressor on the placement plate 105 vibrates, the tray 124 will move vertically back and forth on the outer surface of the multiple vertical rods 102, thereby achieving shock absorption. Shock absorption can reduce the noise of the compressor vibration during operation.

[0045] like Figures 1 to 6 As shown, in one embodiment, multiple air cylinders 112 are fixedly installed on one side of the mounting base 101, and multiple compression plugs 114 are slidably connected to the inner wall of the multiple air cylinders 112. When the support plate 124 vibrates, it will also drive the linkage bar 116 to move up and down reciprocally. At this time, the linkage bar 116 pushes the compression plug 114 to move up and down reciprocally on the inner wall of the air cylinder 112 through the push rod 115, similar to the principle of injection. After the gas is squeezed out inside the air cylinder 112, it is blown to the bottom of the refrigerator compressor through the air pipe 113.

[0046] like Figures 1 to 6 As shown, in one embodiment, air pipes 113 are fixedly installed at the bottom of multiple air cylinders 112. The end of the multiple air pipes 113 away from the multiple air cylinders 112 is located on the side parallel to the placement plate 105. After the gas is squeezed out inside the air cylinders 112, it is blown to the bottom of the refrigerator compressor through the air pipes 113 to dissipate heat, which can improve the heat dissipation efficiency of the refrigerator compressor during operation.

[0047] like Figures 1 to 6As shown, in one embodiment, a cylinder 108 is fixedly installed on the top of the support plate 124, and a movable plate 110 is fixedly installed on the output end of the cylinder 108. Two long rods 109 are fixedly installed on the top of the support plate 124. The cylinder 108 is started by an external power source, and the cylinder 108 pushes the movable plate 110 to slide laterally on the outer surface of the long rods 109. At this time, the movable plate 110 drives the movable bar 111 to move laterally. At this time, the movable bar 111 moves towards the fixed bar 107 inside the elongated hole 106. The two long rods 109 limit the movement of the movable plate 110, making the movement more stable.

[0048] like Figures 1 to 6 As shown, in one embodiment, the movable plate 110 is slidably connected to the outer surface of the two long rods 109. The top of the placement plate 105 is provided with an elongated hole 106. The top of the movable plate 110 is fixedly installed with a movable strip 111. The movable strip 111 moves in the direction of the fixed strip 107 inside the elongated hole 106. The movable strip 111 and the fixed strip 107 can clamp and fix the compressor inside the refrigerator. At this time, the refrigerator compressor is installed on the upper surface of the elongated hole 106.

[0049] like Figures 1 to 6 As shown, in one embodiment, the moving strip 111 passes through the interior of the elongated hole 106, and a fixing strip 107 is fixedly installed on the top of the placement plate 105. The fixing strip 107 is parallel to the moving strip 111, and the parallelism between the fixing strip 107 and the moving strip 111 makes the clamping of the compressor more stable.

[0050] like Figures 1 to 6 As shown, in one embodiment, mounting base 101 is threaded with mounting screws 123 on its surrounding surfaces, and a linkage bar 117 is fixedly installed on one side of the support plate 124. The mounting screws 123 can install the entire device inside the refrigerator.

[0051] like Figures 1 to 6 As shown, in one embodiment, a rack 118 is fixedly installed on the top of the linkage bar 117, and a vertical bar 119 is fixedly installed on one side of the mounting base 101. A rotating rod 121 is movably embedded inside the vertical bar 119. When the support plate 124 moves vertically back and forth on the outer surface of the vertical bar 102, the rack 118 can be driven to move vertically back and forth through the linkage bar 117.

[0052] like Figures 1 to 6As shown, in one embodiment, a gear 120 is fixedly mounted on one end of the rotating rod 121, and a fan 122 is fixedly mounted on the other end of the rotating rod 121. The gear 120 is meshed with the outer surface of the rack 118. The rack 118 meshes with the outer surface of the gear 120, causing the gear 120 to rotate. When the gear 120 rotates clockwise, it drives the fan 122 to rotate through the rotating rod 121, which blows out air. The airflow is horizontal along the upper surface of the placement plate 105, which can dissipate heat from the bottom of the refrigerator compressor during operation.

[0053] Working principle: When in use, the refrigerator compressor is installed above the placement plate 105. After the refrigerator compressor is placed above the placement plate 105, the cylinder 108 is started by an external power source. The cylinder 108 pushes the moving plate 110 to slide laterally on the outer surface of the long rod 109. At this time, the moving plate 110 drives the moving strip 111 to move laterally. At this time, the moving strip 111 moves towards the fixed strip 107 inside the long hole 106. The moving strip 111 and the fixed strip 107 can clamp and fix the compressor inside the refrigerator. At this time, the refrigerator compressor is installed on the upper surface of the long hole 106. The refrigerator compressor will vibrate when it runs. Springs 103 are set around the support plate 124. When the refrigerator compressor on the placement plate 105 vibrates, the support plate 124 will move vertically back and forth on the outer surface of the multiple vertical rods 102, thereby achieving shock absorption. Shock absorption can reduce the noise of the compressor vibration when it is working.

[0054] When the tray 124 moves vertically back and forth on the outer surface of the vertical rod 102, the linkage bar 117 drives the rack 118 to move vertically back and forth. The rack 118 meshes with the outer surface of the gear 120, causing the gear 120 to rotate. When the gear 120 rotates clockwise, it drives the fan 122 to rotate through the rotating rod 121, which will blow out air. The airflow is horizontal along the upper surface of the placement plate 105, which can dissipate heat from the bottom of the refrigerator compressor when it is running.

[0055] Simultaneously, when the tray 124 vibrates, it will also drive the linkage bar 116 to move up and down. At this time, the linkage bar 116 pushes the squeeze plug 114 to move up and down on the inner wall of the air cylinder 112 through the push rod 115, similar to the principle of injection. After the gas is squeezed out inside the air cylinder 112, it is blown to the bottom of the refrigerator compressor through the air pipe 113 to dissipate heat. The dual air blowing heat dissipation can improve the heat dissipation efficiency of the refrigerator compressor during operation.
