Description

Technical Field

[0001] The present invention relates to the technical field of compressor structures, and in particular to a compressor and a refrigeration device. Background Art

[0002] Refrigeration compressors are widely used in commercial freezers and household refrigerators due to their good refrigeration capacity. During the operation of the compressor, the rotation of the motor and the reciprocating motion of the piston will inevitably produce large vibrations, which directly leads to the generation of noise during the operation of the compressor. The distance between the compressor pump body and the foot pad is strongly correlated with the vibration amplitude. Specifically, the larger the distance, the stronger the vibration amplitude. When designing a reciprocating compressor, springs, spring bushings and steel support pins are generally used to reduce the vibration amplitude of the compressor pump body. However, when designing components, the structural design and matching method of the spring bushing and the steel support pin raise the height of the compressor pump body, which in turn affects the operating stability and noise level of the compressor during operation. At the same time, the change in the overall height of the compressor further affects the volume ratio of the refrigerator and affects the economic benefits of the whole machine. Therefore, when designing and manufacturing the compressor, while ensuring the refrigeration effect, it is necessary to pay special attention to the height of the compressor pump body, optimize the internal structure of the compressor, and improve the volume and economic benefits of the refrigerator.

[0043] Refrigeration compressors are widely used in commercial freezers and household refrigerators due to their good refrigeration capacity. During the operation of the compressor, the rotation of the motor and the reciprocating motion of the piston will inevitably produce large vibrations, which directly leads to the generation of noise during the operation of the compressor. The distance between the compressor pump body and the foot pad is strongly correlated with the vibration amplitude. Specifically, the larger the distance, the stronger the vibration amplitude. When designing a reciprocating compressor, springs, spring bushings and steel support pins are generally used to reduce the vibration amplitude of the compressor pump body. However, when designing components, the structural design and matching method of the spring bushing and the steel support pin raise the height of the compressor pump body, which in turn affects the operating stability and noise level of the compressor during operation. At the same time, the change in the overall height of the compressor further affects the volume ratio of the refrigerator and affects the economic benefits of the whole machine. Therefore, when designing and manufacturing the compressor, while ensuring the refrigeration effect, it is necessary to pay special attention to the height of the compressor pump body, optimize the internal structure of the compressor, and improve the volume and economic benefits of the refrigerator.

[0044] In view of this, the present invention proposes a compressor, see Figures 1 to 8 , is an embodiment of the compressor proposed in this application, and the compressor will be described in detail below with reference to specific drawings.

[0045] See also Figures 4 to 5The compressor 100 includes a housing 1, a motor, a crankcase, a cylinder and a support assembly 2.

[0046] In the technical solution of the present invention, the compressor 100 includes the shell 1 and the support assembly 2. The support assembly 2 is mainly used to elastically support the motor and the crankcase in the shell 1 to play a role in buffering and vibration reduction. In combination with the influence of the existing support assembly 2 on the support height of the motor and the crankcase, that is, the influence on the height of the compressor pump body, and the influence of the overall height of the compressor on the performance, the present application adjusts the structure of the support assembly 2 to relatively reduce the height of the support assembly 2, while ensuring its own performance, reducing the influence 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. The support column 21 is used to be fixed to the shell 1 to play 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. On this basis, the present application sets the bushing 22 as a bottom support on the shell 1, that is, the support column 21 is entirely covered in the bushing 22, so that the support column 21 overlaps 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, so as to avoid stacking of the support column 21 and the bushing 22 in the height direction, thereby reducing the height of the support component 2 and meeting the structural and functional requirements required by the present 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 in the up and down directions, and its lower end is connected to the bottom of the shell 1; the second support section 212 is partially protruded upward from the upper end of the first support section 211, so that the upper end surface of the first support section 211 forms a first step surface 213 facing upward on the periphery of the second support section 212; the inner hole of the bushing 22 includes a first sleeve section 221 and a second sleeve section 222, the first sleeve section 221 cooperates with the first support section 211; the second sleeve section 222 is connected to the upper end of the first sleeve section 221, and is inwardly arranged relative to the first sleeve section 221, so as to form a second step surface 224 facing downward between the first sleeve section 221 and the second sleeve section 222, and the second step surface 224 abuts against the first step surface 213. The support column 21 is fixed to the shell 1 and has been described above. The support column 21 is mainly used to support and position the support assembly 2 to further support and position the motor and the crankcase. Therefore, the connection strength between the support column 21 and the shell 1 and the structural strength of the support column 21 itself affect the operating stability of the compressor pump body. Therefore, in this embodiment, the support column 21 is composed of the first support section 211 and the second support section 212. The first support section 211 is connected to the shell 1, and the size of the first support section 211 is larger than the size of the second support section 212, so that the upper end surface of the first support section 211 forms a first step surface 213 facing upward on the periphery of the second support section. In this way, on the one hand, the contact area between the support column 21 and the shell 1 is increased to improve the connection strength between the support column 21 and the shell 1. On the other hand, the bottom volume of the support column 21 is increased to improve the stability of the support column 21, that is, to improve the stability of its own structure. In this way, the structure of the support column 21 In order to meet the above-mentioned connection strength requirements and its own strength requirements, on this basis, the inner hole of the bushing 22 is correspondingly provided with the first sleeve section 221 and the second sleeve section 222, and a second step surface 224 is formed downwardly disposed between the first sleeve section 221 and the second sleeve section 222 to cooperate with the embedding of the support column 21, so that the first step surface 213 abuts against the second step surface 224. On the one hand, it is to ensure the contact connection strength between the bushing 22 and the support column 21, and on the other hand, it is to ensure 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, so as to meet the requirement of reducing the height of the support assembly 2 in this application.

[0048] In addition, 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 on the bottom of the receiving groove 11. In order to further reduce the height of the support assembly 2 in the housing 1, the present embodiment further provides the receiving groove 11 at the bottom of the housing 1 to accommodate the support assembly 2 in the receiving groove 11, thereby reducing the height of the support assembly 2 in 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, so as 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 Figures 6 to 8 , a support protrusion 223 is protruded laterally on the outer side of the lower end of the bushing 22, and the lower end of the spring 23 is supported by the support protrusion 223, and the support protrusion 223 is embedded in the receiving groove 11. It can be understood that the spring 23 sleeved on the bushing 22 can be supported on the bottom of the housing 1, or on the bottom of the receiving groove 11, and 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, so as to provide the spring 23 with flexible support, thereby reducing the wear of the spring 23. On this basis, similar to the function of the first support section 211 provided on the support column 21, the support protrusion 223 is provided at the bottom of the bushing 22, which also increases the contact area between the bushing 22 and the housing 1 to improve its matching stability, and the support protrusion 223 structure itself improves the structural stability of the bushing 22 itself, meeting the structural function requirements.

[0050] For more details, see Figures 4 to 5 , the support protrusion 223 is set lower than the upper end of the receiving groove 11, or the support protrusion 223 is set flush with the upper end of the receiving groove 11. In order to avoid the height increase of the support assembly 2, the height of the support protrusion 223 is limited to not exceed the setting of the receiving groove 11 in this embodiment. It can be understood that the height of the support protrusion 223 and the depth of the receiving groove 11 can be set to be equal, or the height of the support protrusion 223 can be set to be lower than the depth of the receiving groove 11. In this embodiment, it is specifically set that the height of the support protrusion 223 is equal to the groove depth of the receiving groove 11, so as to ensure that their heights overlap to reduce the height of the support assembly 2 in the housing 1, and also to ensure that the intersection surface of the bushing 22 after being embedded in the receiving groove 11 is smooth, so that the overall structure of the compressor 100 is 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. The height of the support protrusion 223 proposed in the present application is defined as 1.5mm to 2mm, and correspondingly, the depth of the receiving groove 11 is also between 1.5mm and 2mm, and specifically, the height of the support protrusion 223 and the depth of the receiving groove 11 are equivalent to each other as described above, and in this embodiment, it is preferred that the height of the support protrusion 223 and the depth of the receiving groove 11 are both 1.8mm. In addition, the present application also defines that the overall height of the bushing 22 should not be greater than 11mm to meet the overall height setting of the compressor, and specifically, in this embodiment, it is preferred that the height of the bushing 22 is 10mm.

[0052] In addition, the support column 21 is integrally provided with the shell 1. It is understandable that the support column 21 is used to be fixed to the shell 1 as described above, that is, the method of fixing the support column 21 to the shell 1 is not limited, including but not limited to using a matching structure to fix, using an adhesive structure to bond, using a welding structure to weld, etc., as long as the support column 21 can be firmly connected to the shell 1. In this embodiment, the support column 21 is integrally formed with the shell 1, which reduces the process steps on the one hand to reduce the production cost, and on the other hand, its structural stability is stronger, and the stronger the connection strength is, the more structural strength requirements are met.

[0053] In addition, a recessed area 12 is formed at the bottom of the shell 1, and the lower end of the support assembly is arranged in the recessed area 12. In order to further reduce the height of the support assembly 2 in the shell 1, the present embodiment further forms the recessed area 12 at the bottom of the shell 1 corresponding to the position of the support assembly 2, thereby forming a recessed support cup structure to reduce the height of the support assembly 2, further meeting the functional requirements proposed in this application. It can be understood that the recessed area 12 formed at the bottom of the shell 1 can also be formed synchronously during the production and manufacturing process of the shell 1, without adding additional process steps for forming operations, thereby reducing costs.

[0054] In addition, the support column 21 and the bushing 22 are interference fit; the spring 23 and the bushing 22 are interference fit. The fixing and matching method between the support column 21 and the bushing 22 can be assisted by other structures, such as connecting with an additional connection structure, bonding with an adhesive structure, etc., but it is obviously more complicated. In this embodiment, the matching method of the support column 21 and the bushing 22 is directly set to interference fit, that is, the support column 21 is embedded in the bushing 22 to achieve the matching and fixing of the two, which has a simple structure, low cost and good effect. In addition, the matching method of the spring 23 and the bushing 22 in this embodiment also adopts interference fit, which also has a simple structure, low cost and good matching performance.

[0055] Also, see Figures 1 to 3 , a base 3 is provided at the bottom of the shell 1 adjacent to its peripheral side, and the base 3 includes a support foot 31, one end of the support foot 31 is connected to the bottom of the shell 1, and the other end extends to the outside of the shell 1, and a buffer pad 32 is provided at the bottom of the support foot 31. Generally, in order to ensure the installation stability of the shell 1, the base 3 structure is also provided outside the shell 1 to support the shell 1. In this embodiment, the base 3 fixed on the shell 1 has the support foot 31 located on the side of the shell 1, that is, compared with being located below the shell 1, the base 3 can have a certain overlap with the shell 1 in the height direction, that is, the distance between the bottom of the shell 1 and the supporting surface is less than the height of the base 3, so as to further reduce the height of the compressor 100 to meet the height reduction requirement proposed in this application. Specifically, the buffer pad 32 is arranged at the lower end of the support foot 31 on the side of the shell 1, and the buffer pad 32 needs to protrude downward from the shell 1 so that the buffer pad 32 is supported on the supporting end surface, thereby achieving support for the shell 1, and the buffer pad 32 structure is arranged to further enhance the buffering and vibration reduction effect and improve the noise environment.

[0056] Furthermore, the bottom lower side surface of the shell 1 is arranged at a position corresponding to the support assembly 2, lower than the upper end surface of the buffer pad 32, and higher than the lower end surface of the buffer pad 32. In order to meet the compression of the height of the compressor 100 and reduce the size of the compressor 100 in the height direction as much as possible, on the basis of reducing the height of the support assembly 2 and reducing the distance between the shell 1 and the support end surface, this embodiment also defines the position of the bottom of the support assembly 2 relative to the base 3 in the height direction. Specifically, the bottom lower side surface of the shell 1 corresponds to the position of the support assembly 2 in the height direction and is located between the upper end surface of the buffer pad 32 and the lower end surface of the buffer pad 32, so that the support assembly 2 and the base 3 also have an overlapping part in the height direction, thereby reducing the height of the compressor 100 and meeting the structural setting requirements.

[0057] In addition, the support assembly 2 further includes a support plate, which is sandwiched between the lower end of the crankcase and the upper end of the motor. The support plate at least partially protrudes from the motor to the outside of the motor to form a mounting portion. The spring 23 is located outside the motor, and the upper end of the spring 23 is mounted on the mounting portion. The spring 23 is mounted through the mounting portion and supported on the housing 1 by the spring 23. In this arrangement, the mounting portion is located on the side of the motor, that is, the spring 23 is also located on the side of the motor, so that the spring 23 and the motor have an overlapping portion in the height direction. Compared with directly arranging the spring 23 below the motor, it reduces the height of the motor in the housing while ensuring the size of the spring 23, thereby reducing the height of the motor and the crankcase in the housing, and further reducing the overall height of the compressor, meeting the design requirements.
