Description

Technical Field

[0001] This invention relates to the field of compressor structure technology, and in particular to a compressor and refrigeration equipment. Background Technology

[0002] Reciprocating compressors are widely used in household and commercial refrigerators and freezers due to their high compression efficiency and ability to provide considerable cooling capacity with relatively low energy consumption. During compressor assembly, the crankcase, stator, support structure, and housing are sequentially fixed with screws. The overall height of the compressor is essentially the sum of the heights of the crankcase, stator, and support structure. The impact of the compressor's overall height must be fully considered in refrigerator and freezer design, as it significantly affects the internal structure design and, consequently, the refrigerator's volume ratio and overall economic efficiency. Therefore, compressor design should aim to reduce the overall height while maintaining performance. Summary of the Invention

[0003] The main objective of this invention is to provide a compressor and refrigeration equipment that aims to reduce the structural height of the compressor.

[0004] To achieve the above objectives, the present invention provides a compressor, wherein the compressor comprises:

[0005] case;

[0006] The motor is housed within the housing and arranged vertically.

[0007] A crankcase, disposed within the housing and located at the upper end of the motor; and,

[0008] A support assembly is disposed within the housing. The support assembly includes a support plate and an elastic support member. The support plate is mounted on the motor and / or the crankcase. The support plate protrudes at least partially from the outside of the motor to form a mounting portion. The elastic support member extends vertically and is located outside the motor. The upper end of the elastic support member is mounted on the mounting portion, and the lower end is mounted on the housing.

[0009] In one embodiment, the support plate is sandwiched between the lower end of the crankcase and the upper end of the motor.

[0010] In one embodiment, the motor includes a stator component and a rotor component, wherein the upper end of the motor has a stator region corresponding to the stator component and a peripheral region located at the stator region, the peripheral region being disposed below the stator region;

[0011] The support plate is disposed between the peripheral area and the crankcase.

[0012] In one embodiment, the upper end of the motor further has an annular stepped portion connecting the stator region and the peripheral region;

[0013] One side of the support plate is adapted to the shape of the annular step portion.

[0014] In one embodiment, the lower end of the elastic support is supported on the bottom of the housing.

[0015] In one embodiment, the bottom of the housing is recessed at the position where the elastic support is installed.

[0016] In one embodiment, the elastic support includes a first support column, a first bushing, and a spring. The first support column is fixed to the bottom of the housing, the first bushing is sleeved on the first support column, the lower end of the spring is sleeved around the first bushing, and the upper end of the spring is mounted on the mounting portion.

[0017] In one embodiment, the bottom of the first bushing is supported on the bottom of the housing.

[0018] In one embodiment, the elastic support further includes a second support column and a second bushing. The second support column is fixed to the mounting portion, the second bushing is sleeved on the second support column, and the upper end of the spring is sleeved around the second bushing to be mounted on the mounting portion.

[0019] In one embodiment, the top of the second bushing is supported on the lower end face of the support plate.

[0020] In one embodiment, the inner bore of the second bushing includes:

[0021] The connecting segment mates with the second support column; and,

[0022] The recessed section is connected to the lower end of the socket section and is recessed relative to the socket section to form an upwardly facing stepped surface between the socket section and the recessed section. The stepped surface abuts against the lower end face of the second support column.

[0023] In one embodiment, the sum of the height of the first bushing and the height of the second bushing is greater than the distance between the lower end face of the support plate and the lower end face of the motor.

[0024] In one embodiment, the second support column is integrally formed with the support plate.

[0025] In one embodiment, the thickness of the support plate is h, then 1mm ≤ h ≤ 1.5mm.

[0026] The present invention also proposes a refrigeration device, wherein the refrigeration device includes the compressor, the compressor including a housing, a motor, a crankcase and a support assembly, the motor being disposed within the housing and arranged vertically; the crankcase being disposed within the housing and located above the motor; the support assembly being disposed within the housing, the support assembly including a support plate and an elastic support member, the support plate being mounted on the motor and / or the crankcase, the support plate at least partially protruding outward from the motor to form a mounting portion, the elastic support member extending vertically and located outside the motor, the upper end of the elastic support member being mounted on the mounting portion and the lower end being mounted on the housing.

[0027] In the technical solution of this invention, the compressor mainly includes the motor, the crankcase, and the housing. The motor and crankcase are fitted together and then mounted within the housing via a support assembly. The support assembly primarily serves to elastically support the motor and crankcase within the housing, providing cushioning and vibration reduction. Considering the impact of the existing support assembly on the support height of the motor and crankcase, and the influence of the overall compressor height on the internal structural design of the refrigeration equipment, this application adjusts the structure of the support assembly to relatively reduce the height of the motor and crankcase supported by the support assembly within the housing, thereby reducing the overall height of the housing. This ensures performance while reducing the overall height of the compressor, meeting design requirements. Specifically, the support assembly includes a support... The compressor includes a support plate and the elastic support member. The support plate is fixedly installed on the crankcase and / or the motor, and the support plate at least partially protrudes outward from the motor to form the mounting portion. The elastic support member is installed through the mounting portion and supported by the elastic support member on the housing. In this configuration, the mounting portion is located to the side of the motor, meaning the elastic support member is also located to the side of the motor, resulting in an overlap between the elastic support member and the motor in the height direction. Compared to directly placing the elastic support member below the motor, this configuration reduces the height of the motor within the housing while maintaining the dimensions of the elastic support member, thereby reducing the height of the motor and the crankcase within the housing, and ultimately reducing the overall height of the compressor, thus meeting design requirements.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the 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.

[0042] Reciprocating compressors are widely used in household and commercial refrigerators and freezers due to their high compression efficiency and ability to provide considerable cooling capacity with relatively low energy consumption. During compressor assembly, the crankcase, stator, support structure, and housing are sequentially fixed with screws. The overall height of the compressor is essentially the sum of the heights of the crankcase, stator, and support structure. The impact of the compressor's overall height must be fully considered in refrigerator and freezer design, as it significantly affects the internal structure design and, consequently, the refrigerator's volume ratio and overall economic efficiency. Therefore, compressor design should aim to reduce the overall height while maintaining performance.

[0043] In view of this, the present invention proposes a compressor, please refer to [link / reference]. Figures 1 to 7 The following is a detailed description of the compressor as described in this application, with reference to the accompanying drawings.

[0044] Please see Figures 1 to 2 as well as Figure 6The compressor 100 includes a housing 1, a motor 2, a crankcase 3, and a support assembly 4. The motor 2 is disposed within the housing 1 and arranged vertically. The crankcase 3 is disposed within the housing 1 and located above the motor 2. The support assembly 4 is disposed within the housing 1 and includes a support plate 41 and an elastic support member 42. The support plate 41 is mounted on the motor 2 and / or the crankcase 3. The support plate 41 at least partially protrudes from the outside of the motor 2 to form a mounting portion 411. The elastic support member 42 extends vertically and is located outside the motor 2. The upper end of the elastic support member 42 is mounted on the mounting portion 411, and the lower end is mounted on the housing 1.

[0045] In the technical solution of this invention, the compressor 100 mainly includes the motor 2, the crankcase 3, and the housing 1. The motor 2 and the crankcase 3 are fitted together and installed within the housing 1 via the support assembly 4. The support assembly 4 is mainly used to elastically support the motor 2 and the crankcase 3 within the housing 1 to provide cushioning and vibration reduction. Considering the influence of the existing support assembly 4 on the support height of the motor 2 and the crankcase 3, and the impact of the overall height of the compressor 100 on the internal structural design of the refrigeration equipment, this application adjusts the structure of the support assembly 4 to relatively reduce the height of the motor 2 and the crankcase 3 supported by the support assembly 4 within the housing 1, thereby reducing the height of the housing 1. This reduces the overall height of the compressor 100 while ensuring its own performance, meeting design requirements. Specifically, the support assembly 4 includes a support plate 41 and a spring... The elastic support member 42 is provided, and the support plate 41 is fixedly installed on the crankcase 3 and / or the motor 2. The support plate 41 at least partially protrudes outward from the motor 2 to form the mounting part 411. The elastic support member 42 is installed through the mounting part 411 and supported by the elastic support member 42 on the housing 1. In this configuration, the mounting part 411 is located to the side of the motor 2, that is, the elastic support member 42 is also located to the side of the motor 2, so that the elastic support member 42 and the motor 2 overlap in the height direction. Compared with directly placing the elastic support member 42 below the motor 2, this configuration reduces the height of the motor 2 in the housing 1 while ensuring the size of the elastic support member 42, thereby reducing the height of the motor 2 and the crankcase 3 in the housing 1, and thus reducing the overall height of the compressor 100, meeting the design requirements.

[0046] Specifically, it can be understood that the support plate 41 can be installed on the crankcase 3, on the motor 2, or simultaneously on both the crankcase 3 and the motor 2. No specific limitation is made here, as long as the support plate 41 can be stably installed and at least partially protrude outwards from the motor 2 to form the mounting portion 411. In this embodiment, the support plate 41 is sandwiched between the lower end of the crankcase 3 and the upper end of the motor 2, thus simultaneously installing on both the crankcase 3 and the motor 2, resulting in a stable structure. Based on this, the portion of the support plate 41 extending beyond the motor 2 forms the mounting portion 411, while the portion sandwiched between the motor 2 and the crankcase 3 forms a fixing portion. This satisfies the structural requirement of the mounting portion 411 providing a lateral mounting space for the elastic support member 42 on the motor 2. Furthermore, given the elasticity of the elastic support member 42 itself, the mounting portion 411 is suspended. At the fixed part, since the mounting plate is clamped between the motor 2 and the crankcase 3, its thickness cannot be too large, otherwise it will affect the overall fit height between the motor 2 and the crankcase 3. However, its strength and toughness must be sufficient to support the crankcase 3 and the motor 2. Therefore, the support plate 41 itself has the characteristics of being thin and tough, that is, having a certain degree of elasticity. Thus, the mounting part 411 suspended in the fixed part also has a certain degree of elasticity. Combined with the elastic support member 42 installed in the mounting part 411, it can provide better elastic support and vibration reduction effects. It should be noted that the support plate 41 can also be set as a structure with high stiffness and low toughness, which can also meet the structural functional requirements, and the elastic support force can be provided solely by the elastic support member 42. Specifically, in this embodiment, the thickness of the support plate 41 is set between 1mm and 1.5mm to reduce the impact on the fit height between the crankcase 3 and the motor 2, while meeting the support strength requirements.

[0047] Specifically, please refer to Figures 3 to 5The motor 2 includes a stator component 21 and a rotor component 22. The upper end of the motor 2 has a stator region corresponding to the stator component 21 and a peripheral region located at the stator region. The peripheral region is set lower than the stator region. A support plate 41 is disposed between the peripheral region and the crankcase 3. Based on the structure of the support plate 41 disposed between the motor 2 and the crankcase 3, and the stator region and peripheral region already provided on the motor 2, and since the peripheral region is used for fixed connection with the crankcase 3 and has little correlation with the performance of the motor 2, in this embodiment, the peripheral region is set lower than the stator region. This avoids the support plate 41 between the motor 2 and the crankcase 3 from affecting the fit between the motor 2 and the crankcase 3, and also avoids the thickness of the support plate 41 from affecting the fit height between the motor 2 and the crankcase 3. Furthermore, the stator region can extend into the crankcase 3, so that... The stator component 21 and the crankcase 3 can partially overlap in the height direction to further reduce the mating height between the crankcase 3 and the motor 2. It should be noted that although the peripheral area can be avoided so that the thickness of the support plate 41 does not affect the mating height between the motor 2 and the crankcase 3, setting the support plate 41 to a thinner structure can, on the one hand, give the support plate 41 a certain degree of elasticity as mentioned above, and on the other hand, the support plate 41 has a smaller impact on the height setting of the peripheral area of ​​the motor 2, making the impact on the performance of the motor 2 less likely, and facilitating the design of the height dimensions of the stator area and the peripheral area.

[0048] In addition, please see Figure 5 The upper end of the motor 2 also has an annular step portion 23 connecting the stator region and the peripheral region; one side of the support plate 41 is adapted to the shape of the annular step portion 23. The peripheral region is lower than the stator region, so that the support plate 41 can be accommodated above the peripheral region, as described above. In this case, for the installation and positioning of the support plate 41, an additional positioning and installation structure could be set on the peripheral region to position and install the support plate 41, but this obviously increases the structural cost. Therefore, in this embodiment, the annular step portion 23 formed by the height difference between the stator region and the peripheral region is used for positioning, resulting in low structural cost. Furthermore, since the stator region is circular, adapting one side of the support plate 41 to the shape of the annular step portion 23 can achieve a preliminary positioning effect. Then, by fixing it with a fixing structure, precise positioning and stable installation of the support plate 41 can be achieved, which is convenient for operation and has a good positioning and fixing effect.

[0049] In addition, please continue to refer to Figure 5The crankcase 3 is connected to the upper end of the motor 2 via a connector 5 passing through the support plate 41. The fixing structure for the support plate 41, crankcase 3, and motor 2 can be varied, including but not limited to welding, bonding, and snap-fitting, as long as it can stably fix the support plate 41, especially a fixing structure that allows the support plate 41 to be fitted to the annular step portion 23 before fixing. In this embodiment, the connector 5 is used to fix the crankcase 3 and motor 2. The connector 5 passes through the support plate 41, thus positioning the support plate 41. The fastening of the crankcase 3 and motor 2, i.e., clamping it to the support plate 41, achieves stable fixing of the support plate 41. Therefore, no additional fixing structure is needed; the connection structure between the crankcase 3 and motor 2, i.e., the connector 5, is sufficient to position and fix the support plate 41. This method is simple, low-cost, and effective. Meanwhile, the connecting piece 5 is used to connect the crankcase 3 and the motor 2. The connecting piece 5 has a large fitting size with the crankcase 3 and the motor 2, making the connection more stable.

[0050] Furthermore, the connector 5 includes a screw thread. The connector 5 is mainly used to bind the crankcase 3 and the motor 2 in the height direction. Therefore, the connector 5 can actually be a flexible connecting rope or a connecting rod with a clamping structure, so that the clamping parts at both ends of the connecting rod can respectively clamp the crankcase 3 and the motor 2 to complete the fixed connection between them. That is, the specific structure of the connector 5 is not limited, as long as it can meet the above-mentioned fixed connection requirements. In this embodiment, the connector 5 is set as the screw thread, which has a mature structure, low cost, good fixed connection effect, and meets the required connection strength.

[0051] In addition, please see Figures 3 to 4The lower end of the elastic support 42 is supported on the bottom of the housing 1. The main purpose of the elastic support 42 is to suspend the mating structure of the crankcase 3 and the motor 2 within the housing 1, and to provide elastic support for the crankcase 3 and the motor 2 through the elastic force of the elastic support 42 itself, thereby achieving a vibration reduction effect. Therefore, the support point of the elastic support 42 within the housing 1 is not actually limited, as long as it can provide vertical support to the mating structure of the crankcase 3 and the motor 2. For example, it can be supported on the side of the housing 1, so that multiple elastic support 42s are arranged around the mating structure of the crankcase 3 and the motor 2 to balance the horizontal force and achieve the purpose of suspending the mating structure of the crankcase 3 and the motor 2. However, such a setting is obviously cumbersome. In this embodiment, the elastic support 42 is directly set to be supported on the bottom of the housing 1 to directly provide vertical elastic support, which meets the structural functional requirements and has a lower design cost.

[0052] Furthermore, the bottom of the housing 1 is recessed at the location where the elastic support 42 is installed. To ensure that the elastic support 42 has sufficient dimensions to provide adequate elastic support force and buffer stroke, this embodiment has a recessed bottom in the housing 1 to accommodate the end structure of the elastic support 42. This further reduces the height of the mating structure between the crankcase 3 and the motor 2 within the housing 1, thereby further reducing the height of the compressor 100 and meeting overall structural requirements.

[0053] For details, please continue reading Figures 3 to 4The elastic support member 42 includes a first support column 421, a first bushing 422, and a spring 423. The first support column 421 is fixed to the bottom of the housing 1. The first bushing 422 is sleeved on the first support column 421. The lower end of the spring 423 is sleeved around the first bushing 422, and the upper end of the spring 423 is mounted on the mounting part 411. The bottom of the first bushing 422 is supported on the bottom of the housing 1. The first support column 421 is used to fix the housing 1, serving a positioning and supporting function. The first bushing 422 is sleeved on the support column to install the spring 423, reducing wear on the spring 423 and extending its service life. In this embodiment, the first bushing 422 is positioned so that its bottom is supported on the housing 1, meaning the first support column 421 is entirely enclosed within the first bushing 422. This ensures that the first support column 421 and the first bushing 422 overlap in the height direction. When the first bushing 422 is sleeved on the first support column 421, the height of the combined structure is equal to the height of the first bushing 422. This avoids the first support column 421 and the first bushing 422 stacking in the height direction, reducing the height of the mating structure and meeting the structural and functional requirements of this application. Furthermore, the first bushing 422 directly supports the housing 1, providing stable support for the spring 423.

[0054] In addition, please continue to refer to Figures 3 to 4The elastic support member 42 further includes a second support column 424 and a second bushing 425. The second support column 424 is fixed to the mounting portion 411, and the second bushing 425 is sleeved on the second support column 424. The upper end of the spring 423 is sleeved around the second bushing 425 for mounting on the mounting portion 411. The top of the second bushing 425 is supported on the lower end surface of the support plate 41. Similar to the lower end of the elastic support member 42, the upper end of the elastic support member 42 is provided with the second support column 424 and the second bushing 425. Similarly, the second support column 424 is fixed to the mounting part 411, serving as a positioning support. The second bushing 425 is sleeved on the second support column 424 for mounting the spring 423, reducing wear on the spring 423 and extending its service life. In this embodiment, the second bushing 425 is positioned with its top supported on the lower end face of the support plate 41, meaning the second support column 424 is entirely enclosed within the second bushing 425. This ensures that the second support column 424 and the second bushing 425 overlap in the height direction. When the second bushing 425 is sleeved on the second support column 424, the height of the assembly is equal to the height of the second bushing 425. This avoids the second support column 424 and the second bushing 425 stacking in the height direction, reducing the height of the mating structure and meeting the structural functional requirements of this application. Furthermore, the second bushing 425 directly supports the housing 1, providing stable support for the spring 423.

[0055] For further information, please refer to [link / reference]. Figures 3 to 4The inner hole of the second bushing 425 includes a sleeve section 425a and a recessed section 425b. The sleeve section 425a mates with the second support post 424. The recessed section 425b is connected to the lower end of the sleeve section 425a and is recessed relative to the sleeve section 425a to form an upwardly facing stepped surface between the sleeve section 425a and the recessed section 425b. The stepped surface abuts against the lower end face of the second support post 424. The second bushing 425 is sleeved on the second support column 424, as described above. In this embodiment, the inner hole of the second bushing 425 is configured with a connecting section 425a and a recessed section 425b with different inner diameters. This allows the stepped surface formed between the connecting section 425a and the recessed section 425b to abut against the lower end face of the second support column 424, thereby increasing the mating area between the second bushing 425 and the second support column 424 and improving mating stability. Furthermore, the recessed section 425b can actually be a closed structure, meaning the second bushing 425 is configured with an upward-facing closed hole on its upper end face to accommodate the second support column 424 within the closed hole, thus maximizing the improvement of the second bushing 425. The mating area between the second bushing 425 and the second support column 424 is 25. However, with this arrangement, since the size of the sleeve section 425a is similar to that of the second support column 424, when the second bushing 425 is fitted onto the second support column 424, the second support column 424 will close the opening of the aforementioned closed hole, thereby preventing the internal gas from flowing out and hindering the installation of the second bushing 425. Therefore, in this embodiment, the inner hole on the second bushing 425 is set as a through-hole, and the inner hole includes the sleeve section 425a and the inward section 425b. Based on the structure that avoids the impact of the aforementioned air pressure on the installation, the stepped surface is provided to mate with the second support column 424 to meet the requirement of increasing the mating area between the second bushing 425 and the second support column 424.

[0056] Specifically, the cooperation structure between the elastic support member 42 and the housing 1 and the mounting part 411 has been described above. It should be noted that the cooperation structure between the upper end of the elastic support member 42 and the mounting part 411 and the cooperation structure between the lower end of the elastic support member 42 and the housing 1 are not limited to the embodiments described above. Simply put, the spring 423 can also be directly connected to the housing 1 or the mounting part 411 to achieve a stable connection and provide elastic support for the cooperation structure between the crankcase 3 and the motor 2. In this embodiment, the elastic support member 42 is configured such that the lower end of the spring 423 cooperates with the first bushing 422 and is then sleeved on the first support column 421, and the upper end of the spring 423 cooperates with the second bushing 425 and is then sleeved on the second support column 424, so as to have all the beneficial effects described above.

[0057] Specifically, the sum of the heights of the first bushing 422 and the second bushing 425 is greater than the distance between the lower end face of the support plate 41 and the lower end face of the motor 2. Since the elastic support member 42 is located to the side of the motor 2, to prevent the motor 2 from colliding with the housing 1 when the elastic support member 42 vibrates and compresses, in this embodiment, the sum of the heights of the first bushing 422 and the second bushing 425 within the elastic support member 42 is set to be greater than the distance between the lower end face of the support plate 41 and the lower end face of the motor 2. That is, when the spring 423 within the elastic support member 42 is compressed to the point where the first bushing 422 and the second bushing 425 abut, the height of the lower end face of the motor 2 is still higher than the bottom of the first bushing 422, thus satisfying the above structural requirements.

[0058] In addition, please see Figures 6 to 7The second support column 424 is integrally formed with the support plate 41. It is understood that the method by which the second support column 424 is fixed to the mounting part 411 has been described above. That is, the method by which the second support column 424 is fixed to the mounting part 411 is not limited, including but not limited to using a mating structure for fixing, an adhesive structure for bonding, or a welding structure for welding, as long as the second support column 424 is securely connected to the mounting part 411. In this embodiment, the second support column 424 and the mounting part 411 are integrally formed, which reduces process steps and lowers manufacturing costs. Furthermore, it provides stronger structural stability and connection strength, meeting structural strength requirements. It should be noted that the method by which the first support column 421 is fixed to the shell 1 is also not limited. Similarly, in this embodiment, the first support column 421 and the shell 1 are integrally formed, which also has the beneficial effects of reducing process steps, lowering manufacturing costs, and providing stronger structural stability and connection strength, meeting structural strength requirements.

[0059] The present invention also proposes a refrigeration device, which includes a compressor 100. The specific structure of the compressor 100 is as described in the above embodiments. Since the refrigeration device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
