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] Refrigeration compressors are widely used in commercial freezers and household refrigerators due to their excellent cooling capacity. During compressor operation, the rotation of the motor and the reciprocating motion of the piston inevitably generate significant vibrations, directly leading to noise generation. The distance between the compressor pump body and the feet shows a strong correlation with the vibration amplitude; specifically, the greater the distance, the stronger the vibration. In the design of reciprocating compressors, springs, spring bushings, and steel support pins are typically used to mitigate the vibration amplitude of the compressor pump body. However, in the component design, the structural design and fit of the spring bushings and steel support pins actually increases the height of the compressor pump body, thus affecting the operational stability and noise level of the compressor. Furthermore, changes in the overall height of the compressor further affect the refrigerator's volumetric efficiency, impacting the overall economic efficiency of the unit. Therefore, when designing and manufacturing compressors, while ensuring cooling performance, it is crucial to pay close attention to the height of the compressor pump body, optimize the internal structure of the compressor, and improve the refrigerator's volumetric efficiency and economic benefits.

The bushing is sleeved on the support column, and the bottom of the bushing is supported on the bottom of the housing. The upper end of the spring is mounted on the motor and / or the crankcase, and the lower end of the spring is sleeved around the bushing.

[0013] The second support segment is partially protruding upward from the upper end of the first support segment, so that the upper end surface of the first support segment forms an upward-facing first step surface on the periphery of the second support segment.

[0014] The inner bore of the bushing includes:

[0015] The first connecting segment mates with the first supporting segment; and...

[0016] The second socket segment is connected to the upper end of the first socket segment and is recessed relative to the first socket segment to form a downwardly facing second step surface between the first socket segment and the second socket segment, the second step surface abutting against the first step surface.

[0017] In one embodiment, the bottom of the housing is provided with a receiving groove, the support column is fixed to the bottom of the receiving groove, and the bottom of the bushing is at least partially embedded in the receiving groove so that the bottom of the bushing is supported by the bottom of the receiving groove.

[0018] In one embodiment, a support protrusion protrudes laterally from the outer side of the lower end of the bushing, the lower end of the spring is supported on the support protrusion, and the support protrusion is embedded in the receiving groove.

[0019] In one embodiment, the support protrusion is disposed below the upper end of the receiving groove, or the support protrusion is disposed flush with the upper end of the receiving groove.

[0020] In one embodiment, the height of the support protrusion is A, then 1.5mm ≤ A ≤ 2mm; and / or,

[0021] If the depth of the receiving groove is B, then 1.5mm ≤ B ≤ 2mm.

[0022] In one embodiment, the height of the bushing is C, where C ≤ 11 mm.

[0023] In one embodiment, a base is provided at the bottom of the housing near its periphery. The base includes a support leg, one end of which is connected to the bottom of the housing, and the other end extends outward from the housing. A cushioning pad is provided at the bottom of the support leg.

[0024] The bottom lower side of the housing is positioned below the upper surface of the buffer pad and above the lower surface of the buffer pad at the location corresponding to the support component.

[0025] In one embodiment, the support assembly further includes a support plate sandwiched between the lower end of the crankcase and the upper end of the motor. The support plate at least partially protrudes outward from the motor to form a mounting portion. The spring is located outside the motor, and the upper end of the spring is mounted on the mounting portion.

[0026] The present invention also proposes a refrigeration device, wherein the refrigeration device includes a compressor, the compressor including a housing, a motor, a crankcase, a cylinder, and a support assembly. The crankcase is disposed in the housing and has a vertically penetrating mounting shaft hole. The cylinder is located inside the housing and disposed on the upper side of the crankcase. The motor is located inside the housing and disposed on the lower side of the crankcase. The motor includes a rotor component and a stator component, and has a through hole penetrating its upper and lower ends. The crankshaft is located inside the housing and rotatably engages with the mounting shaft hole.

The upper end of the spring is mounted on the motor 2 and / or the crankcase 3, and the lower end of the spring 23 is sleeved around the bushing.

[0027] In the technical solution of this invention, the compressor includes a housing and a support assembly. The support assembly is mainly used to elastically support the motor and the crankcase within the housing to provide cushioning and vibration reduction. Considering the impact of the existing support assembly on the support height of the motor and crankcase (i.e., on the height of the compressor pump body) and the impact of the overall compressor height on performance, this application adjusts the structure of the support assembly to relatively reduce its height. This ensures its own performance while reducing the impact on the overall stability and noise level of the compressor. Specifically, the support assembly includes a support column, a bushing, and a... The spring and the support column are used to fix the spring to the housing and play a positioning and supporting role. The bushing is sleeved on the support column to install the spring, reduce the wear of the spring and extend its service life. Based on this, this application sets the bushing to be supported at the bottom of the housing, that is, the support column is completely covered by the bushing, so that the support column coincides with the bushing in the height direction. When the bushing is sleeved on the support column, the height of the two components is the height of the bushing, thereby avoiding the stacking of the support column and the bushing in the height direction, realizing the reduction of the height of the support component and meeting the structural and functional requirements of this application.

[0043] Refrigeration compressors are widely used in commercial freezers and household refrigerators due to their excellent cooling capacity. During compressor operation, the rotation of the motor and the reciprocating motion of the piston inevitably generate significant vibrations, directly leading to noise generation. The distance between the compressor pump body and the feet shows a strong correlation with the vibration amplitude; specifically, the greater the distance, the stronger the vibration. In the design of reciprocating compressors, springs, spring bushings, and steel support pins are typically used to mitigate the vibration amplitude of the compressor pump body. However, in the component design, the structural design and fit of the spring bushings and steel support pins actually increases the height of the compressor pump body, thus affecting the operational stability and noise level of the compressor. Furthermore, changes in the overall height of the compressor further affect the refrigerator's volumetric efficiency, impacting the overall economic efficiency of the unit. Therefore, when designing and manufacturing compressors, while ensuring cooling performance, it is crucial to pay close attention to the height of the compressor pump body, optimize the internal structure of the compressor, and improve the refrigerator's volumetric efficiency and economic benefits.

[0044] In view of this, the present invention proposes a compressor, please refer to [link / reference]. Figures 1 to 8 The following is a detailed description of the compressor as described in this application, with reference to the accompanying drawings.

[0045] Please see Figures 4 to 5The compressor 100 includes a housing 1, a motor, a crankcase, a cylinder, and a support assembly 2. The crankcase is located within the housing 1 and has a through mounting hole extending vertically. The cylinder is located inside the housing 1 and is positioned above the crankcase. The motor is located inside the housing 1 and is positioned below the crankcase. The motor includes a rotor assembly and a stator assembly, and has through holes extending through its upper and lower ends. The crankshaft is located inside the housing 1 and rotatably engages with the mounting hole. The upper end of the crankshaft is provided with... An eccentric part is provided that is connected to the connecting rod of the cylinder, and the lower end of the crankshaft is connected to the rotor component; the support assembly 2 is located inside the housing 1, and the support assembly 2 includes a support column 21, a bushing 22 and a spring 23. The support column 21 is fixed to the bottom of the housing 1, the bushing 22 is sleeved on the support column 21, and the bottom of the bushing 22 is supported on the bottom of the housing 1. The upper end of the spring 23 is installed on the motor 2 and / or the crankcase 3, and the lower end of the spring 23 is sleeved around the bushing 22.

[0046] In the technical solution of this invention, the compressor 100 includes the housing 1 and the support assembly 2. The support assembly 2 is mainly used to elastically support the motor and the crankcase within the housing 1 to provide buffering and vibration reduction. Considering the impact of the existing support assembly 2 on the support height of the motor and crankcase, i.e., on the height of the compressor pump body, and the impact of the overall height of the compressor on performance, this application adjusts the structure of the support assembly 2 to relatively reduce its height. While ensuring its own performance, this reduces the impact on the overall stability and noise level of the compressor. Specifically, the support assembly 2 includes the support column 21, the bushing 22, and the spring 23. 21 is used to fix it to the housing 1 and plays a positioning and supporting role. The bushing 22 is sleeved on the support column 21 to install the spring 23, reduce the wear of the spring 23 and extend its service life. Based on this, the bushing 22 is set to support the bottom of the housing 1, that is, the support column 21 is completely covered by the bushing 22, so that the support column 21 coincides with the bushing 22 in the height direction. When the bushing 22 is sleeved on the support column 21, the height of the two components is the height of the bushing 22, thereby avoiding the support column 21 and the bushing 22 from stacking in the height direction, realizing the reduction of the height of the support component 2, and meeting the structural and functional requirements of this application.

[0047] Specifically, the support column 21 includes a first support section 211 and a second support section 212. The first support section 211 extends vertically and its lower end is connected to the bottom of the housing 1. The second support section 212 is partially protruding upward from the upper end of the first support section 211, so that the upper end surface of the first support section 211 forms an upwardly facing first step surface 213 on the periphery of the second support section 212. The inner hole of the bushing 22 includes a first socket section 221 and a second socket section 222. The first socket section 221 mates with the first support section 211. The second socket section 222 is connected to the upper end of the first socket section 221 and is recessed relative to the first socket section 221, so that a downwardly facing second step surface 224 is formed between the first socket section 221 and the second socket section 222, and the second step surface 224 abuts against the first step surface 213. As described above, the support column 21 is fixed to the housing 1. The support column 21 is mainly used to support and position the support assembly 2, further supporting and positioning the motor and the crankcase. Therefore, the connection strength between the support column 21 and the housing 1, as well as the structural strength of the support column 21 itself, affects the operational stability of the compressor pump. Therefore, in this embodiment, the support column 21 is composed of a first support segment 211 and a second support segment 212. The first support segment 211 is connected to the housing 1, and the size of the first support segment 211 is larger than the size of the second support segment 212, so that the upper end surface of the first support segment 211 forms an upward-facing first step surface 213 around the periphery of the second support segment. This increases the contact area between the support column 21 and the housing 1, thereby improving the connection strength between the support column 21 and the housing 1, and also increases the bottom volume of the support column 21, thereby improving the stability of the support column 21, i.e., improving the stability of its own structure. Thus, the structure of the support column 21... To meet the aforementioned connection strength requirements and self-strength requirements, the inner hole of the bushing 22 is provided with the first socket section 221 and the second socket section 222, and a downwardly facing second step surface 224 is formed between the first socket section 221 and the second socket section 222 to cooperate with the embedding of the support column 21, so that the first step surface 213 and the second step surface 224 abut against each other. On the one hand, this ensures the contact connection strength between the bushing 22 and the support column 21, and on the other hand, it ensures the structure of the bushing 22 covering the support column 21 in the height direction, that is, the first support section 211 is also sleeved and accommodated in the bushing 22, which meets the requirement of reducing the height of the support component 2 in this application.

[0048] Furthermore, a receiving groove 11 is provided at the bottom of the housing 1, the support column 21 is fixed to the bottom of the receiving groove 11, and the bottom of the bushing 22 is at least partially embedded in the receiving groove 11, so that the bottom of the bushing 22 is supported by the bottom of the receiving groove 11. To further reduce the height of the support assembly 2 within the housing 1, this embodiment also provides the receiving groove 11 at the bottom of the housing 1 to accommodate the support assembly 2 within the receiving groove 11, thereby reducing the height of the support assembly 2 within the housing 1. Specifically, the support column 21 is fixed to the bottom of the receiving groove 11, the bushing 22 is sleeved on the support column 21, and the bushing 22 is embedded in the receiving groove 11 to further increase the contact area between the bushing 22 and the housing 1, thereby improving the connection stability between the bushing 22 and the housing 1.

[0049] In addition, see the following: Figures 6 to 8 The lower end of the bushing 22 has a lateral support protrusion 223 protruding outward. The lower end of the spring 23 is supported by the support protrusion 223, which is embedded in the receiving groove 11. It can be understood that the spring 23 fitted onto the bushing 22 can be supported at the bottom of the housing 1 or at the bottom of the receiving groove 11. In this embodiment, the support protrusion 223 is formed on the outer periphery of the bottom of the bushing 22 to support the spring 23, thereby providing flexible support and reducing wear on the spring 23. Similar to the function of the first support section 211 on the support column 21, the support protrusion 223 at the bottom of the bushing 22 also increases the contact area between the bushing 22 and the housing 1, improving their fit stability. Furthermore, the structure of the support protrusion 223 itself enhances the structural stability of the bushing 22, meeting structural functional requirements.

[0050] For details, please refer to [link / reference]. Figures 4 to 5 The supporting protrusion 223 is set below the upper end of the receiving groove 11, or the supporting protrusion 223 is flush with the upper end of the receiving groove 11. To avoid increasing the height of the supporting component 2, in this embodiment, the height of the supporting protrusion 223 is limited to not exceeding the receiving groove 11. It can be understood that the height of the supporting protrusion 223 and the depth of the receiving groove 11 can be set to be equivalent, or the height of the supporting protrusion 223 can be set to be lower than the depth of the receiving groove 11. In this embodiment, the height of the supporting protrusion 223 is set to be equivalent to the groove depth of the receiving groove 11, so as to ensure that their heights overlap, thereby reducing the height of the supporting component 2 in the housing 1, and also ensuring the smoothness of the interface surface after the bushing 22 is embedded in the receiving groove 11, so as to make the overall structure of the compressor 100 coordinated and stable.

[0051] Specifically, the height of the support protrusion 223 is A, then 1.5mm ≤ A ≤ 2mm; the depth of the receiving groove 11 is B, then 1.5mm ≤ B ≤ 2mm. Here, the height of the support protrusion 223 proposed in this application is limited to 1.5mm to 2mm, and correspondingly, the depth of the receiving groove 11 is also between 1.5mm and 2mm. Specifically, the height of the support protrusion 223 and the depth of the receiving groove 11 are equivalent, as described above. In this embodiment, it is preferable that both the height of the support protrusion 223 and the depth of the receiving groove 11 are 1.8mm. In addition, this application also limits the overall height of the bushing 22 to no more than 11mm to meet the overall height setting of the compressor. Specifically, in this embodiment, it is preferable that the height of the bushing 22 is 10mm.

[0052] Furthermore, the support column 21 is integrally formed with the housing 1. It is understood that the method by which the support column 21 is fixed to the housing 1 has been described above; that is, the method by which the support column 21 is fixed to the housing 1 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 support column 21 is stably connected to the housing 1. In this embodiment, the support column 21 and the housing 1 are integrally formed, which reduces process steps to lower manufacturing costs, and also provides stronger structural stability and connection strength, meeting structural strength requirements.

[0053] Furthermore, a recessed area 12 is formed at the bottom of the housing 1, and the lower end of the support component is disposed in the recessed area 12. To further reduce the height of the support component 2 within the housing 1, this embodiment also forms the recessed area 12 at the bottom of the housing 1 corresponding to the position of the support component 2, thereby forming a recessed support cup structure to reduce the height of the support component 2 and further meet the functional requirements proposed in this application. It is understood that the recessed area 12 formed at the bottom of the housing 1 can also be formed simultaneously during the manufacturing process of the housing 1 without adding additional process steps for forming operations, thus reducing costs.

[0054] Furthermore, the support column 21 and the bushing 22 are interference-fitted; the spring 23 and the bushing 22 are also interference-fitted. The fixing method between the support column 21 and the bushing 22 could involve using other auxiliary structures, such as additional connecting structures or adhesive bonding, but these are obviously cumbersome. In this embodiment, the fit between the support column 21 and the bushing 22 is directly set as an interference fit, that is, the support column 21 is embedded within the bushing 22 to achieve a fixed fit, resulting in a simple structure, low cost, and good effect. In addition, the fit between the spring 23 and the bushing 22 in this embodiment is also an interference fit, similarly possessing the characteristics of a simple structure, low cost, and good performance.

[0055] In addition, please see Figures 1 to 3 A base 3 is provided near the bottom of the housing 1, adjacent to its periphery. The base 3 includes a support leg 31, one end of which is connected to the bottom of the housing 1, and the other end extends outward from the housing 1. A buffer pad 32 is provided at the bottom of the support leg 31. Generally, to ensure the installation stability of the housing 1, the base 3 structure is also provided outside the housing 1 to support the housing 1. In this embodiment, the support leg 31 of the base 3 fixed on the housing 1 is located to the side of the housing 1. That is, compared to being located below the housing 1, the base 3 can overlap with the housing 1 in the height direction to a certain extent, so that the distance from the bottom of the housing 1 to the support surface is less than the height of the base 3, thereby further reducing the height of the compressor 100 to meet the height reduction requirement proposed in this application. Specifically, a buffer pad 32 is provided at the lower end of the support leg 31 on the side of the housing 1. The buffer pad 32 needs to protrude downward from the housing 1 so that the buffer pad 32 is supported on the support end face, thereby supporting the housing 1. The structure of the buffer pad 32 further improves the buffering and vibration reduction effect and improves the noise environment.

[0056] Furthermore, the lower bottom surface of the housing 1, corresponding to the support component 2, is lower than the upper end surface of the buffer pad 32 but higher than the lower end surface of the buffer pad 32. To meet the compression requirements of the compressor 100 and minimize its height, in addition to reducing the height of the support component 2 and the distance between the housing 1 and the support end surface, this embodiment further defines the position of the bottom of the support component 2 relative to the base 3 in the height direction. Specifically, the lower bottom surface of the housing 1, corresponding to the position of the support component 2, is located in the height direction between the upper and lower end surfaces of the buffer pad 32, so that the support component 2 and the base 3 also overlap in the height direction, thereby reducing the height of the compressor 100 and meeting the structural requirements.

[0057] Furthermore, the support assembly 2 also includes a support plate sandwiched between the lower end of the crankcase and the upper end of the motor. The support plate at least partially protrudes outward from the motor to form a mounting portion. The spring 23 is located outside the motor, and its upper end is mounted on the mounting portion. The spring 23 is mounted through the mounting portion and supported by the housing 1. This arrangement, with the mounting portion located to the side of the motor, means the spring 23 is also located to the side of the motor, resulting in a vertical overlap between the spring 23 and the motor. Compared to directly placing the spring 23 below the motor, this arrangement reduces the height of the motor within the housing while maintaining the dimensions of the spring 23, thereby reducing the height of the motor and crankcase within the housing, and ultimately reducing the overall height of the compressor, meeting design requirements.

[0058] This invention also proposes a refrigeration device, which includes a compressor. The specific structure of the compressor 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 elaborated here.
