Description

Technical Field

[0001] This utility model relates to the technical field of refrigeration equipment, and in particular to a refrigerator compressor and refrigeration equipment. Background Technology

[0002] Miniaturization and increased efficiency of compressors are market trends. In existing refrigerators, the motor and cylinder of the compressor are arranged vertically, so the compressor's center of gravity is generally near the crankshaft's center of gravity, and the compressor springs are directly mounted on the motor stator. In this configuration, the horizontal distance between the geometric center of all compressor support springs and the center of gravity is small, resulting in greater compressor stability. However, if the motor and cylinder are arranged horizontally side-by-side, the horizontal distance of the compressor increases, and the center of gravity shifts away from the center of rotation. If the springs are still directly mounted on the motor stator, there is a risk of excessive vibration, especially in the cylinder head, which is prone to wobbling. Utility Model Content

[0003] The main purpose of this invention is to provide a refrigerator compressor and refrigeration equipment, which aims to reduce the risk of vibration caused by the cylinder support and improve the stability of the cylinder support and compressor.

[0004] To achieve the above objectives, the refrigerator compressor proposed in this utility model includes:

The length of the third mounting plate facing the cylinder bracket is greater than the length of the third mounting plate away from the cylinder bracket.

[0013] In one embodiment, the height difference between the first mounting plate and the third mounting plate is h, and the third mounting plate is farther away from the bottom of the housing than the first mounting plate, with a height of 5mm ≤ h ≤ 25mm.

[0017] In one embodiment, a limiting post is provided on the side of the crankshaft bracket away from the motor.

[0018] This utility model also proposes a refrigeration device, including a refrigerator compressor as described above.

[0019] The refrigerator compressor in this invention includes a housing, a motor, a cylinder, a crankcase, and a shock-absorbing assembly. The motor and cylinder are connected by a drive.

[0033] Reference Figures 1 to 3 This utility model proposes a method comprising:

[0034] Casing 10;

[0035] Motor 21 and cylinder, wherein the motor 21 is connected to the cylinder in a driving connection;

[0036] A crankcase, comprising a crankshaft bracket 31 and a cylinder bracket 32, wherein a motor 21 and the cylinder bracket 32 ​​are arranged side-by-side in a horizontal direction, the crankshaft bracket 31 is connected to the cylinder bracket 32, the motor 21 is mounted on the crankshaft bracket 31, and the cylinder is mounted on the cylinder bracket 32; and

[0037] The vibration damping assembly includes a vibration damping bracket 41, at least one first elastic element 42, and two second elastic elements 43. At least one vibration damping bracket 41 is connected to both the side of the motor 21 facing the cylinder bracket 32 ​​and the side away from the cylinder bracket 32. The vibration damping bracket 41 facing the cylinder bracket 32 ​​is connected to the housing 10 through at least one first elastic element 42, and the vibration damping bracket 41 away from the cylinder bracket 32 ​​is connected to the housing 10 through two second elastic elements 43. The cylinder bracket 32 ​​is located between the two second elastic elements 43.

[0038] The refrigerator compressor in this utility model includes a housing 10, a motor 21, a cylinder, a crankcase, and a shock-absorbing assembly. The motor 21 is connected to the cylinder via a transmission. The crankcase includes a crankshaft support 31 and a cylinder support 32 arranged horizontally. The crankshaft support 31 is connected to the cylinder support 32. The motor 21 is mounted on the crankshaft support 31, and the cylinder is mounted on the cylinder support 32. The shock-absorbing assembly includes a shock-absorbing bracket 41, at least one first elastic element 42, and two second elastic elements 43. The motor 21 is connected to both the side facing the cylinder support 32 and the side away from the cylinder support 32. There is at least one shock-absorbing bracket 41. The shock-absorbing bracket 41 facing the cylinder bracket 32 ​​is connected to the housing 10 through at least one first elastic element 42. The shock-absorbing bracket 41 away from the cylinder bracket 32 ​​is connected to the housing 10 through two second elastic elements 43. The cylinder bracket 32 ​​is located between the two second elastic elements 43. That is, the second elastic elements 43 extend through the shock-absorbing bracket 41 to a position that is horizontal and parallel to the cylinder bracket 32, thereby supporting the cylinder bracket 32, thereby reducing the risk of vibration of the cylinder bracket 32, and thus improving the stability of the cylinder bracket 32 ​​and the compressor.

[0039] In one embodiment, the refrigerator compressor further includes a crankshaft 22 and a connecting rod 23. A cylinder bore is provided on the cylinder support 32. The crankshaft 22 is drivenly connected to the motor 21 and is rotatably connected to the crankshaft support 31. One end of the connecting rod 23 is drivenly connected to the end of the crankshaft 22 away from the motor 21, and the other end of the connecting rod 23 is slidably connected to the cylinder bore through a cylinder pin. The end of the connecting rod 23 connected to the crankshaft 22 rotates under the drive of the crankshaft 22, and the end of the connecting rod 23 facing the cylinder bore reciprocates within the cylinder bore.

[0040] It should be noted that the motor 21 and the cylinder bracket 32 ​​are arranged side by side in the horizontal direction, that is, the motor 21 and the cylinder bracket 32 ​​are arranged side by side in the axial direction of the cylinder bore. This means that the projections of the motor 21 and the cylinder bracket 32 ​​on the vertical plane at least partially overlap. In other words, the motor 21 and the cylinder bracket 32 ​​can be partially arranged side by side in the axial direction of the cylinder bore, or one of the motor 21 and the cylinder bracket 32 ​​can completely contain the other. Furthermore, compared to the prior art solution where the motor 21 and the cylinder are stacked vertically, the technical solution of this application arranges the motor 21 and the cylinder side by side in the horizontal direction, thereby reducing the overall height of the refrigerator compressor, thus lowering the center of gravity of the refrigerator compressor, thereby reducing the vibration amplitude of the refrigerator compressor, and thus reducing the noise generated by the refrigerator compressor during operation.

[0041] In one embodiment, the crankshaft bracket 31 is provided with a clearance hole, through which the connecting rod extends into the piston bore 321. Understandably, since the cylinder bracket 32 ​​and the motor 21 are arranged side-by-side, at least a portion of the piston bore 321 is located below the upper surface of the crankshaft bracket 31. One end of the connecting rod 23 rotates under the drive of the crankshaft 22, while the other end reciprocates along the axial direction of the piston bore 321. The end of the connecting rod near the crankshaft is located above the crankshaft bracket, and the end near the cylinder bracket is located below the crankshaft bracket. Therefore, a clearance hole is necessary to increase the movement space of the connecting rod 23, thereby reducing interference with the connecting rod 23 and improving the stability of the refrigerator compressor's operation.

[0042] Furthermore, it can be understood that one end of the connecting rod rotates under the drive of the crankshaft, while the other end reciprocates within the piston bore. If the angle between the crankshaft support and the cylinder support deviates too much from 90°, the connecting rod may easily jam within the piston bore, thus affecting the normal operation of the connecting rod and the refrigerator compressor. Therefore, in one embodiment of this application, the perpendicularity between the crankshaft support 31 and the cylinder support 32 is 0.1mm. It can be understood that during the design phase, the crankshaft support 31 and the cylinder support 32 are precisely perpendicular. However, certain errors are inevitable during actual manufacturing. Therefore, the crankshaft support 31 and the cylinder support 32 will not be perfectly perpendicular. Thus, the perpendicularity between the crankshaft support 31 and the cylinder support 32 is set to 0.1mm. Here, 0.1mm of perpendicularity means that the maximum tilt of the crankshaft support 31 relative to the cylinder support 32 must not exceed 0.1mm. Understandably, by machining the perpendicularity of the crankshaft support 31 and the cylinder support 32 to 0.1mm, the sliding of the connecting rod 23 within the piston bore 321 becomes smoother, reducing friction and wear caused by the non-perpendicularity of the cylinder support 32 and the crankshaft support 31. This improves the operating accuracy of the connecting rod 23, thereby extending the service life of the refrigerator compressor, reducing energy loss due to friction and wear, and ultimately improving the energy efficiency of the entire mechanical system. Conversely, if the crankshaft support 31 and the cylinder support 32 are not perpendicular, additional stress and deformation will occur between the connecting rod 23 and the cylinder support 32 during operation within the piston bore 321, affecting the normal operation of the machine. Alternatively, in another embodiment, the angle between the crankshaft support and the cylinder support can be limited, such as between 89.5° and 90.5°, or between 89° and 91°.

[0043] In one embodiment, the shock-absorbing bracket 41 includes two sub-bases 411 and a connecting plate 44. One end of each sub-base 411 is connected to the motor 21, and the other end is connected to the housing 10 via the first elastic element 42 or the second elastic element 43. The two sub-bases 411 are connected by the connecting plate 44. Understandably, connecting adjacent sub-bases 411 via the connecting plate 44 forms a more stable structure, which helps to disperse the vibration and impact forces generated by the motor 21 during operation, improving the stability and durability of the entire structure. Especially under high speed or high load conditions, it can more effectively reduce vibration and noise, ensuring the smooth operation of the motor 21. Simultaneously, the motor 21 generates certain mechanical effects during operation, including vibration and torque. The connection via the connecting plate 44 allows for a more reasonable distribution of these mechanical effects, preventing excessive local stress that could lead to structural damage. Furthermore, this connection method also helps to improve the overall rigidity and strength of the motor 21, enabling it to better withstand various mechanical challenges. Finally, using the connecting plate 44 to connect the adjacent sub-base 411 simplifies the installation process of the shock absorber bracket 41. Due to the presence of the connecting plate 44, it is easier to align and fix the motor 21 to the shock absorber bracket 41, reducing installation errors and debugging time; furthermore, this connection method makes disassembly and reassembly easier when maintenance or replacement of the motor 21 is required.

[0044] The motor 21 has a sub-base 411 connected to each of its four corners. A connecting plate 44 can connect two sub-bases 411 facing the cylinder bracket 32, and another connecting plate 44 connects two sub-bases 411 moving away from the cylinder bracket 32. Alternatively, the connecting plate 44 can connect two adjacent sub-bases 411 extending from the crankshaft bracket 31 to the cylinder bracket 32. Alternatively, all four corner sub-bases 411 can be connected via corresponding connecting plates 44.

[0045] Furthermore, one end of the sub-base 411 is connected to the bottom of the motor 21, and the other end of the sub-base 411 extends away from the bottom of the housing 10. Understandably, if the end of the sub-base 411 away from the motor 21 extends towards the bottom of the housing 10, the shock-absorbing components would occupy a large portion of the refrigerator compressor's height, thus hindering the reduction of the refrigerator compressor's height. Therefore, by extending the other end of the sub-base 411 away from the bottom of the housing 10, the first elastic element 42 and the second elastic element 43 are arranged side-by-side with the motor 21, thereby reducing the height of the refrigerator compressor. The side-by-side arrangement of the first elastic element 42 and the second elastic element 43 with the motor 21 can be partially side-by-side, or one element can encompass the other.

[0046] Furthermore, the connecting plate 44 is arc-shaped. The arc-shaped connecting plate 44 can better disperse the vibration and impact forces generated by the motor 21 during operation, avoiding excessive stress concentration at any local location on the connecting plate 44. In contrast, a straight connecting plate 44 is more prone to stress concentration under load, thus increasing the risk of structural failure. The arc-shaped connecting plate 44 has a certain degree of flexibility, better adapting to the minor deformations generated by the motor 21 during operation; this flexible connection helps reduce additional stress and vibration caused by deformation, thereby improving the stability and durability of the entire structure. At the same time, the arc-shaped connecting plate 44 is also designed to accommodate the shape of the motor 21.

[0047] Specifically, the sub-base 411 includes a first mounting plate 411a, a second mounting plate 411b, and a third mounting plate 411c. The first mounting plate 411a and the third mounting plate 411c are connected via the second mounting plate 411b. The first mounting plate 411a is connected to the motor 21. The third mounting plate 411c is connected to the housing 10 via the first elastic member 42 or the second elastic member 43. The length of the third mounting plate 411c facing the cylinder bracket 32 ​​is greater than the length of the third mounting plate 411c away from the cylinder bracket 32. When the third mounting plate 411c is a shock-absorbing bracket 41 facing the cylinder bracket 32, the third mounting plate 411c is connected to the housing 10 via the second elastic member 43; when the third mounting plate 411c is a shock-absorbing bracket 41 away from the cylinder bracket 32, the third mounting plate 411c is connected to the housing 10 via the first elastic member 42. Understandably, by making the length of the third mounting plate 411c facing the cylinder bracket 32 ​​greater than the length of the third mounting plate 411c away from the cylinder bracket 32, the second elastic member 43 provides an additional support point for the cylinder bracket 32, thereby reducing the risk of vibration of the cylinder bracket 32 ​​and improving the stability of the cylinder bracket 32 ​​and the compressor.

[0048] Reference Figure 3 and Figure 4Specifically, the height difference between the first mounting plate 411a and the third mounting plate 411c is h, and the third mounting plate 411c is located away from the bottom of the housing 10 relative to the first mounting plate 411a, with a distance of 5mm ≤ h ≤ 25mm. That is, the distance between the third mounting plate 411c and the cylinder bracket 32 ​​is less than the distance between the first mounting plate 411a and the cylinder bracket 32, meaning the third mounting plate 411c is located above the first mounting plate 411a. Thus, by setting a height difference between the first mounting plate 411a and the third mounting plate 411c, the height occupied by the shock absorber bracket 41, the first elastic element 42, and the second elastic element 43 is reduced, which is beneficial for the miniaturization of the compressor. Therefore, if h > 25mm, the height of the shock absorber bracket 41 will be too high. In this case, the length of the first elastic element 42 and / or the second elastic element 43 will need to be longer. This will increase the risk of tilting or deformation of the first elastic element 42 and / or the second elastic element 43 during shock absorption, thereby reducing the stability and reliability of the connection between the motor 21 and the crankcase, and consequently reducing the stability of the refrigerator compressor. At the same time, an excessively high h will also cause the shock absorber bracket 41 to easily interfere with the crankcase, the housing 10, or other internal components of the refrigerator compressor, thus increasing the installation space of the shock absorber bracket 41 and hindering its miniaturization. If h < 5mm, it indicates that the elastic deformation space of the first elastic element 42 and / or the second elastic element 43 is too small. This means that the vibration generated by the motor 21 cannot be effectively absorbed and dispersed by the first elastic element 42 and / or the second elastic element 43, which may easily cause the motor 21 and cylinder to collide with the housing 10, thereby reducing the stability and reliability of the motor 21 and cylinder, and consequently reducing the service life of the refrigerator compressor.

[0049] In one embodiment, multiple shock-absorbing brackets 41 are disposed at the corners of the motor 21, and the third mounting plate 411c extends away from the crankshaft bracket 31. There is free space at the corners of the motor 21, thus reducing the installation space occupied by the shock-absorbing brackets 41 by placing them at these corners. Furthermore, extending the third mounting plate 411c away from the crankshaft bracket 31 reduces interference between the third mounting plate 411c and the motor 21, facilitating the installation of the shock-absorbing brackets 41 and further reducing the installation space occupied by the shock-absorbing brackets 41, which is beneficial for the miniaturization of the refrigerator compressor.

[0050] Reference Figure 5 and Figure 6In one embodiment, the damping assembly further includes a pin and a bushing 45. The first elastic element 42 and the second elastic element 43 are both springs. One end of the spring is fixedly connected to the damping bracket 41 via the pin, and the other end of the spring is fixedly connected to the housing 10 via the bushing 45. By providing the pin and bushing 45, the stability and reliability of the connection between the spring and the damping bracket 41 and the housing 10 are improved. Simultaneously, the pin extends along the axial direction of the spring, thereby reducing the possibility of the spring tilting or deforming during deformation, thus improving the stability and reliability of the motor 21 and the crankcase. Further, the first elastic element 42 and the second elastic element 43 can also be bellows, silicone blocks, rubber blocks, or other elastic elements.

[0051] Specifically, the spring has an initial state and a compressed state. In the compressed state, the minimum sum of the spring length and the thickness of the bushing 45 is H, where 20mm ≤ H ≤ 40mm. By optimizing the height of the spring in the compressed state, the spring is ensured to perform optimally within a limited space.

[0052] Furthermore, a limiting post 311 is provided on the side of the crankshaft bracket 31 facing away from the motor 21. Understandably, vibrations will occur during the operation of the motor 21. If the crankshaft bracket 31 vibrates upwards, it will stretch the first elastic element 42 and the second elastic element 43. If the first elastic element 42 and the second elastic element 43 are stretched too much, they will detach from the housing 10. Therefore, by setting the limiting post 311, the upward vibration height of the crankcase is limited. If the upward vibration amplitude of the crankcase is too large, the limiting post 311 will contact the housing 10, thereby limiting the crankcase from continuing to rise, thus improving the stability and reliability of the damping assembly.
