Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically to a support component for a compressor, a compressor using the support component, and a refrigeration device using the compressor. Background Technology

[0002] Current reciprocating compressors generally use spring support systems to improve unit noise and vibration.

[0003] For example, an existing compressor support assembly includes a support bracket, a compressor core, a core assembly, a compression spring, and a compression spring assembly. The support bracket has several first assembly parts arranged radially inward on its inner side, and several second assembly parts arranged radially outward on its outer side. The first assembly parts are located within the orthographic projection of the compressor core or on the side of the compressor core, and are connected to the compressor core via the core assembly. The second assembly parts are at least partially located outside the orthographic projection of the compressor core, and the compression spring is located on the lower end face of the second assembly part. The second assembly part is connected to the upper end of the compression spring via the compression spring assembly, and the compression spring extends vertically. By arranging the second assembly parts on the support bracket radially outward, so that at least part of the second assembly parts are located outside the orthographic projection of the compressor core, the space limitation between the compression spring and the motor frame is eliminated, allowing for a significant increase in the inner diameter of the compression spring. This improves lateral support stability, significantly reduces the amplitude of the compressor core at low speeds, and substantially reduces compressor vibration and noise.

[0004] However, this type of support structure does not guide the spring in the direction of spring extension and contraction. The spring is prone to misalignment and deformation during compression and extension, resulting in lower reliability for supports in directions other than spring compression and contraction. After harsh transportation conditions such as drops, rollovers, and prolonged vibration, the compression spring is prone to detachment, leading to failure of the spring support system and causing damage to internal compressor parts, abnormal noise, and other problems.

[0005] Therefore, a more optimized support structure needs to be considered. Utility Model Content

[0006] The primary objective of this invention is to provide a compressor support assembly that can reduce the offset and deformation of the spring in the support component during compression and stretching processes, thereby improving the reliability of the support.

[0007] The second objective of this invention is to provide a compressor that can reduce the offset and deformation of the support component spring during compression and stretching processes, thereby improving the reliability of the support.

[0008] The third objective of this invention is to provide a refrigeration device that can reduce the offset and deformation of the spring in the support component during compression and stretching processes, thereby improving the reliability of the support.

[0009] To achieve the aforementioned first objective, the compressor support assembly provided by this utility model includes a spring, a support sleeve, and a mounting sleeve. The support sleeve has a spring mounting hole, and a spring support portion is provided at the bottom of the spring mounting hole. The spring is installed in the spring mounting hole, and the first end of the spring abuts against the spring support portion. The ratio of the outer diameter of the spring to the inner diameter of the spring mounting hole is in the range of 0.92 to 1. The mounting sleeve has a fitting hole, and a protrusion is provided at the top of the fitting hole. The second end of the spring is fitted onto the outer peripheral wall of the protrusion. The support sleeve is inserted into the fitting hole, and the ratio of the outer diameter of the support sleeve to the inner diameter of the fitting hole is in the range of 0.92 to 1.

[0010] As can be seen from the above solution, the compressor support assembly of this utility model is provided with an mounting sleeve and a support sleeve, which are installed as independent units on the upper and lower ends of the spring. By cooperating with the two to circumferentially limit the spring, the offset and deformation of the spring during compression and tension can be reduced, thereby improving the reliability of the support system.

[0011] In a further embodiment, a support column is provided at the center of the spring support, and the first end of the spring is fitted onto the outer periphery of the support column.

[0012] Therefore, by setting up a support column so that the first end of the spring is fitted onto the outer periphery of the support column, the spring can be easily fixed and the spring can be prevented from shifting during movement.

[0013] In a further design, the outer diameter of the support column is equal to the inner diameter of the spring component.

[0014] Therefore, the outer diameter of the support column is equal to the inner diameter of the spring component, which ensures the stability of the connection between the spring component and the support column.

[0015] In a further embodiment, the support includes a guide section located at one end away from the spring support section.

[0016] Therefore, it can be seen that by setting a guide part, the support column can play a guiding role when installing spring components, making it easier for the spring components to be assembled in place.

[0017] In a further embodiment, a mounting hole is provided at the middle position of the spring support, and the support column also includes a mating part, which is interference-fitted with the mounting hole.

[0018] Therefore, by setting mounting holes and mating parts for interference fit, it is easy to install the support column in the spring mounting hole.

[0019] In a further design, the height H3 of the spring component satisfies the following condition: ; ; ;in, The thickness of the spring support portion. The height of the support column, The height of the convex column. The depth of the spring mounting hole. This refers to the hole depth of the fitting.

[0020] Therefore, the height H3 of the spring component satisfies the following condition: ; ; This ensures that the support column and protrusion do not collide when the spring is compressed, the support sleeve and mounting sleeve do not collide, and the mounting sleeve does not collide with the compressor housing.

[0021] In a further embodiment, the support assembly also includes a connector mounted on top of the support sleeve.

[0022] Therefore, it can be seen that by setting up connectors, it can be used to connect the compressor core.

[0023] In a further embodiment, the top of the mounting sleeve is provided with a connection hole, and the connector is installed in the connection hole.

[0024] Therefore, it can be seen that the mounting sleeve, by providing connection holes, facilitates the installation of connectors.

[0025] In a further embodiment, the connecting hole is located inside the protruding post.

[0026] Therefore, placing the connecting hole inside the protruding post can make full use of space and achieve the effect of miniaturization.

[0027] In a further design, the connector is a screw.

[0028] Therefore, using screws as connectors facilitates the installation of support components.

[0029] To achieve the second objective of this utility model, the compressor provided by this utility model includes a compressor core, a housing, and a support assembly. The compressor core is installed inside the housing via the support assembly; the support assembly is the aforementioned support assembly.

[0030] To achieve the third objective of this utility model, the refrigeration equipment provided by this utility model includes a compressor, and the compressor uses the above-mentioned compressor. Attached Figure Description

[0049] Compressor Example: like Figure 1 and Figure 2 As shown, in this embodiment, the compressor includes a housing 1, a compressor core 2, and a support assembly 3. The compressor core 2 is mounted inside the housing 1 via the support assembly 3. The support assembly 3 serves as a connection between the compressor core 2 and the housing 1, reducing vibrations transmitted from the compressor core 2 to the outside of the housing 1 and the noise generated by these vibrations during compressor operation. The number of support assemblies 3 can be set as needed; in this embodiment, three support assemblies 3 are arranged in a triangular pattern to ensure the stability of the compressor core 2 during installation.

[0050] See Figure 3 , Figure 4 and Figure 5 The support component 3 includes a support sleeve 31, a mounting sleeve 32, and a spring element 33.

[0051] See Figure 6 and Figure 7The support sleeve 31 is provided with a spring mounting hole 311, and a spring support part 312 is provided at the bottom of the spring mounting hole 311. The spring member 33 is installed in the spring mounting hole 311, and the first end of the spring member 33 abuts against the spring support part 312.

[0052] See Figure 8 and Figure 9 The mounting sleeve 32 is provided with a mounting hole 321, and a protrusion 322 is provided at the top of the mounting hole 321. The second end of the spring member 33 is fitted onto the outer peripheral wall of the protrusion 322. The support sleeve 31 is inserted into the mounting hole 321. The ratio of the outer diameter of the support sleeve 31 to the inner diameter of the mounting hole 321 is in the range of 0.92 to 1. In this embodiment, the inner diameter of the mounting hole 321 and the outer diameter of the support sleeve 31 are both D2.

[0053] A support column 34 is also provided at the center of the spring support 312, and the first end of the spring member 33 is fitted onto the outer periphery of the support column 34. By fitting the spring member 33 onto the outer periphery of the support column 34, it is easy to fix the spring member 33 and prevent it from shifting during movement. The outer diameter of the support column 34 is equal to the inner diameter of the spring member 33, and both the outer diameter of the support column 34 and the inner diameter of the spring member 33 are D1. The equality of the outer diameter of the support column 34 and the inner diameter of the spring member 33 ensures the stability of the connection between the spring member 33 and the support column 34.

[0054] See Figure 10 and Figure 11 The support column 34 includes a guide portion 341, which is located at one end away from the spring support portion 312. By providing the guide portion 341, the support column 34 can guide the spring member 33 during installation, making it easier for the spring member 33 to be assembled into place.

[0055] Depend on Figure 6 It can be seen that a mounting hole 313 is provided at the middle position of the spring support 312, and the support column 34 also includes a mating part 342, which is interference-fitted with the mounting hole 313. By providing the mounting hole 313 and the mating part 342 for interference fit, the support column 34 can be easily installed in the spring mounting hole 311.

[0056] In this embodiment, the height H3 of the spring member 33 satisfies the following condition: ; ; .in, The thickness of the spring support 312 The height of the support column is 34. The height of the convex pillar 322. The depth of the spring mounting hole 311, The depth of the fitting hole 321. The height H3 of the spring member 33 satisfies the following condition: ; ; This ensures that when the spring element 33 is under pressure, the support column 34 and the protrusion 322 do not collide, the support sleeve 31 and the mounting sleeve 32 do not collide, and the mounting sleeve 32 does not collide with the compressor housing 1.

[0057] Depend on Figure 3 , Figure 4 and Figure 5 As can be seen, in this embodiment, the support assembly 3 further includes a connector 35, which is installed on the top of the support sleeve 31. By providing the connector 35, it can be used to connect the compressor core 2.

[0058] Depend on Figure 9 It is known that the top of the mounting sleeve 32 is provided with a connecting hole 323, and the connector 35 is installed in the connecting hole 323. The mounting sleeve 32, by providing the connecting hole 323, facilitates the installation of the connector 35. In this embodiment, the connecting hole 323 is located inside the protrusion 322. By placing the connecting hole 323 inside the protrusion 322, space can be fully utilized, achieving a miniaturized structure. The type of connector 35 can be set as needed. In this embodiment, the connector 35 is a screw, the extension direction of which is the same as the extension direction of the spring 33, and the screw is screwed to the compressor core 2. Using a screw as the connector 35 facilitates the installation of the support assembly 3.

[0059] In this embodiment, when the compressor is working, the compressor core 2 will vibrate. This vibration will exert a force on the support assembly 3. The support assembly 3, through the compression and tension of the spring member 33, reduces the collision between the compressor core 2 and the housing 1. When the spring member 33 is in the stretched state, the state of the support assembly 3 is as follows: Figure 4 As shown. When the spring member 33 is in the compressed state, the state of the support assembly 3 is as follows. Figure 12 As shown. When the spring 33 is in the compressed state, a certain gap is maintained between the upper end of the support sleeve 31 and the bottom of the fitting hole 321, and a certain gap is maintained between the protrusion 322 and the top of the support column 13 to avoid collision.

[0060] As described above, the compressor support assembly 3 of this utility model is provided with an mounting sleeve 32 and a support sleeve 31, which are installed as independent units on the upper and lower ends of the spring. By cooperating with the two to circumferentially limit the spring, the offset and deformation of the spring during compression and tension can be reduced, thereby improving the reliability of the support system.

[0061] Refrigeration equipment example: In this embodiment, the refrigeration equipment includes a compressor, and the compressor used is the one described above. Refrigeration equipment includes air conditioners, refrigerators, and other devices that require a compressor.

[0062] It should be noted that the above are only preferred embodiments of the present utility model, but the design concept of the utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall also fall within the protection scope of the present utility model.
