[0002] Reciprocating compressors are widely used in household or commercial refrigerators and freezers because of their high compression efficiency and ability to provide considerable refrigeration capacity at low energy consumption. When assembling the compressor, the crankcase and stator components, support structure, and housing are fixed in sequence by screws.

When designing refrigerators and freezers, the impact of the overall height of the compressor needs to be fully considered. The overall height of the compressor will actually affect the design of the internal structure of the refrigerator, and further affect the volume ratio of the refrigerator and the economic benefits of the whole machine.

[0042] Reciprocating compressors are widely used in household or commercial refrigerators and freezers because of their high compression efficiency and ability to provide considerable refrigeration capacity at low energy consumption. When assembling the compressor, the crankcase and stator components, support structure, and housing are fixed in sequence by screws. The overall height of the compressor is basically determined as the sum of the heights of the crankcase, stator components, and support structure. When designing refrigerators and freezers, the impact of the overall height of the compressor needs to be fully considered. The overall height of the compressor will actually affect the design of the internal structure of the refrigerator, and further affect the volume ratio of the refrigerator and the economic benefits of the whole machine. Therefore, when designing the compressor, the overall height should be reduced as much as possible while ensuring performance.

[0043] In view of this, the present invention proposes a compressor, see Figures 1 to 7 , is an embodiment of the compressor proposed in this application, and the compressor will be described in detail below with reference to specific drawings.

[0044] See also Figure 1 to Figure 2 as well as Figure 6The compressor 100 includes a shell 1, a motor 2, a crankcase 3 and a support assembly 4, wherein the motor 2 is disposed in the shell 1 and arranged in an up-down direction; the crankcase 3 is disposed in the shell 1 and is located at the upper end of the motor 2; the support assembly 4 is disposed in the shell 1, and the support assembly 4 includes a support plate 41 and an elastic support member 42, wherein the support plate 41 is mounted on the motor 2 and / or the crankcase 3, and the support plate 41 at least partially protrudes from the outside of the motor 2 to form a mounting portion 411, and the elastic support member 42 extends in an up-down direction and is located on the outside of 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 shell 1.

[0045] In the technical solution of the present invention, the compressor 100 mainly includes the motor 2, the crankcase 3 and the shell 1. The motor 2 is installed in the shell 1 through the support assembly 4 after matching with the crankcase 3. The support assembly 4 is mainly used to elastically support the motor 2 and the crankcase 3 in the shell 1 to play a role in buffering and vibration reduction. In combination with the influence of the existing support assembly 4 on the support height of the motor 2 and the crankcase 3, and the influence of the overall height of the compressor 100 on the internal structure design of the refrigeration equipment, the present 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 in the shell 1, thereby reducing the height of the shell 1, so as to reduce the overall height of the compressor 100 while ensuring its own performance, thereby meeting the design requirements. Specifically, the support assembly 4 includes the support plate 41 and the elastic support plate 42. The elastic support member 42 is a support plate 41 fixedly mounted on the crankcase 3 and / or the motor 2, and the support plate 41 at least partially protrudes from the motor 2 to the outside of the motor 2 to form the mounting portion 411, and the elastic support member 42 is mounted through the mounting portion 411, and is supported on the shell 1 by the elastic support member 42. In this way, the mounting portion 411 is located on the side of the motor 2, that is, the elastic support member 42 is also located on the side of the motor 2, so that the elastic support member 42 and the motor 2 have an overlapping portion in the height direction. Compared with directly arranging the elastic support member 42 below the motor 2, it reduces the height of the motor 2 in the shell 1 while ensuring the size of the elastic support member 42, so as to reduce the height of the motor 2 and the crankcase 3 in the shell 1, thereby reducing the overall height of the compressor 100, thereby meeting the design requirements.

[0046] Specifically, it can be understood that the support plate 41 can be installed on the crankcase 3, or on the motor 2, or synchronously installed on 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 from the motor 2 to the outside of the motor 2 to form the mounting portion 411. In this embodiment, the support plate 41 is clamped between the lower end of the crankcase 3 and the upper end of the motor 2, so as to be synchronously installed on the crankcase 3 and the motor 2, and the structure is stable. Based on this, the part of the support plate 41 that exceeds the motor 2 forms the mounting portion 411, and the part clamped between the motor 2 and the crankcase 3 forms a fixing portion, which meets the structural requirement that the mounting portion 411 is provided for the installation of the elastic support member 42 on the side of the motor 2, and on the basis that the elastic support member 42 itself has elasticity, the mounting portion 411 is suspended. In the fixing part, at this time, because 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 matching height of the motor 2 and the crankcase 3, and its strength and toughness need to be able to support the crankcase 3 and the motor 2, so the support plate 41 itself has the characteristics of thin thickness and strong toughness, that is, it has a certain elasticity, so the mounting part 411 suspended on the fixing part also has a certain elasticity, combined with the elastic support member 42 installed on the mounting part 411, it can provide better elastic support and vibration reduction effect. It should be noted here that the support plate 41 can also be set as a structure with high rigidity and low toughness, which can also meet the structural function requirements, and only the elastic support member 42 can provide elastic support force. Specifically, the thickness of the support plate 41 in this embodiment is set to between 1mm and 1.5mm to reduce the impact on the matching height of the crankcase 3 and the motor 2, while meeting the support strength requirements.

[0047] Specifically, see Figures 3 to 5, the motor 2 includes a stator component 21 and a rotor component 22, wherein 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, and the peripheral region is arranged lower than the stator region; the support plate 41 is arranged between the peripheral region and the crankcase 3. Based on the structure that the support plate 41 is arranged between the motor 2 and the crankcase 3, and the stator region and the peripheral region are arranged on the motor 2 itself, and the peripheral region is used to be fixedly connected to the crankcase 3, and its performance correlation with the motor 2 is relatively small, so in this embodiment, the peripheral region is arranged to be lower than the stator region, on the one hand, the support plate 41 arranged between the motor 2 and the crankcase 3 is avoided to affect the matching between the motor 2 and the crankcase 3, on the other hand, the thickness of the support plate 41 is avoided to affect the matching height between the motor 2 and the crankcase 3, and on the other hand, the stator region can extend into the crankcase 3, so that The stator component 21 and the crankcase 3 may partially overlap in the height direction to further reduce the fitting height between the crankcase 3 and the motor 2. It should be noted here that although the peripheral area can be avoided so that the thickness setting of the support plate 41 will not affect the fitting height between the motor 2 and the crankcase 3, the support plate 41 is set to a thinner structure. On the one hand, as described above, the support plate 41 can have a certain elasticity. On the other hand, the support plate 41 has little effect on the height setting of the peripheral area of ​​the motor 2, which makes it less likely to affect the performance of the motor 2, and facilitates the height dimension design of the stator area and the peripheral area.

[0048] Also, 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, which has been described above. At this time, for the installation and positioning of the support plate 41, an additional positioning and mounting structure can be provided on the peripheral region to position and install the support plate 41, but it is obvious that the structural cost is increased. 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, and the structural cost is low. Since the stator region is circular, one side of the support plate 41 is adapted to the shape of the annular step portion 23, which can achieve the effect of preliminary positioning. Then, it is fixed by a fixing structure, so that the support plate 41 can be accurately positioned and firmly installed, which is easy to operate and has a good positioning and fixing effect.

[0049] Also, please read Figure 5, the crankcase 3 is connected to the upper end of the motor 2 through the connector 5 passing through the support plate 41. The fixing structure of the support plate 41, the crankcase 3 and the motor 2 can be various, including but not limited to welding, bonding, clamping, etc., which can achieve stable fixation of the support plate 41, especially a fixing structure that can be fixed after the support plate 41 is adapted to the annular step portion 23. In this embodiment, the connector 5 is provided to connect the crankcase 3 and the motor 2, and the connector 5 passes through the support plate 41, that is, the positioning of the support plate 41 is achieved, and the fastening of the crankcase 3 and the motor 2, that is, clamping on the support plate 41, thereby achieving stable fixation of the support plate 41. In this way, there is no need to set up an additional fixing structure, and the positioning and fixing of the support plate 41 can be achieved by using the connection structure of the crankcase 3 and the motor 2, that is, using the connector 5 to connect the crankcase 3 and the motor 2. The structure is simple, the cost is low, and the effect is good. At the same time, the connecting member 5 is used to connect the crankcase 3 and the motor 2. The matching size of the connecting member 5, the crankcase 3 and the motor 2 is large, and the connection is more stable.

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

[0051] Also, see Figure 3 to Figure 4, the lower end of the elastic support member 42 is supported on the bottom of the housing 1. The main purpose of the elastic support member 42 is to suspend the matching structure of the crankcase 3 and the motor 2 in the housing 1, and to achieve elastic support of the crankcase 3 and the motor 2 through the elastic force of the elastic support member 42 itself, so as to achieve a vibration reduction effect. Therefore, the supporting point of the elastic support member 42 in the housing 1 is not actually limited, and it is sufficient to provide a supporting force in the height direction to the matching structure of the crankcase 3 and the motor 2. For example, it can be supported on the side of the housing 1, so that a plurality of elastic support members 42 are surrounded by the matching structure of the crankcase 3 and the motor 2 to balance the force in the horizontal direction, so as to achieve the purpose of suspending the matching structure of the crankcase 3 and the motor 2. However, it is obvious that such a setting is more complicated. In this embodiment, the elastic support member 42 is directly set to be supported at the bottom of the housing 1 at the lower end, so as to directly provide an elastic supporting force in the height direction, meet the structural function requirements, and have a low design cost.

[0052] Furthermore, the bottom of the housing 1 is concavely arranged at the position where the elastic support member 42 is installed. In order to ensure that the elastic support member 42 has a sufficient size to provide sufficient elastic support force and buffer stroke, the bottom of the housing 1 is concavely arranged in this embodiment to accommodate the end structure of the elastic support member 42, so that the height of the matching structure of the crankcase 3 and the motor 2 in the housing 1 can be further reduced, so as to further reduce the height of the compressor 100 and meet the overall structural requirements.

[0053] For details, please continue to see Figure 3 to Figure 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 on the outer periphery of the first bushing 422. The upper end of the spring 423 is mounted on the mounting portion 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 be fixed to the housing 1 to play a positioning and supporting role. The first bushing 422 is sleeved on the support column to install the spring 423, reduce the wear of the spring 423, and extend its service life. On this basis, in this embodiment, the first bushing 422 is set to be supported at the bottom of the housing 1, that is, the first support column 421 is entirely covered in the first bushing 422, so that the first support column 421 overlaps with the first bushing 422 in the height direction. When the first bushing 422 is sleeved on the first support column 421, the height of the two components is the height of the first bushing 422, so as to avoid the first support column 421 and the first bushing 422 from stacking in the height direction, and realize the reduction of the height of the matching structure of the first support column 421 and the first bushing 422, so as to meet the structural and functional requirements of the present application. And the first bushing 422 is directly supported on the housing 1, and its support for the spring 423 is also relatively stable.

[0054] Also, please read Figure 3 to Figure 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. The second bushing 425 is sleeved on the second support column 424. The upper end of the spring 423 is sleeved on the outer periphery of the second bushing 425 to be mounted 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 portion 411 to play a positioning and supporting role. The second bushing 425 is sleeved on the second support column 424 to install the spring 423, reduce the wear of the spring 423, and extend its service life. On this basis, in this embodiment, the second bushing 425 is set to be supported on the lower end surface of the support plate 41, that is, the second support column 424 is entirely covered in the second bushing 425, so that the second support column 424 overlaps with the second bushing 425 in the height direction. When the second bushing 425 is sleeved on the second support column 424, the height of the two components is the height of the second bushing 425, so as to avoid the second support column 424 and the second bushing 425 from stacking in the height direction, and realize the reduction of the height of the matching structure of the second support column 424 and the second bushing 425, so as to meet the structural and functional requirements of the present application. And the second bushing 425 is directly supported on the housing 1, and its support for the spring 423 is also relatively stable.

[0055] For further information, please refer to Figure 3 to Figure 4The inner hole of the second bushing 425 includes a sleeve section 425a and a retracted section 425b, and the sleeve section 425a cooperates with the second support column 424; the retracted section 425b is connected to the lower end of the sleeve section 425a, and is retracted relative to the sleeve section 425a, so as to form an upward step surface between the sleeve section 425a and the retracted section 425b, and the step surface abuts against the lower end surface of the second support column 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 set to the sleeve section 425a and the retracted section 425b with different inner diameters, so that the step surface formed between the sleeve section 425a and the retracted section 425b abuts against the lower end surface of the second support column 424 to increase the matching area between the second bushing 425 and the second support column 424 to improve the matching stability. On this basis, the retracted section 425b can actually be a closed structure, that is, the second bushing 425 is set to have a closed hole with an opening facing upward on its upper end surface, so as to accommodate the second support column 424 in the closed hole, thereby maximizing the improvement of the second bushing 425. 25 and the matching area of ​​the second support column 424, but with such a configuration, because the size of the sleeve section 425a is similar to that of the second support column 424, when the second bushing 425 is sleeved on the second support column 424, the second support column 424 will close the opening of the above-mentioned closed hole, thereby preventing the internal gas from flowing out, which hinders the installation of the second bushing 425. Therefore, in this embodiment, the inner hole on the second bushing 425 is set to be a through setting, and the inner hole includes the sleeve section 425a and the retracted section 425b. On the basis of the structure to avoid the above-mentioned air pressure affecting the installation, the step surface and the second support column 424 are matched to meet the demand for increasing the matching area of ​​the second bushing 425 and the second support column 424.

[0056] Specifically, the matching structure of the elastic support member 42 and the shell 1 and the mounting portion 411 has been described above. It should be noted here that the matching structure of the upper end of the elastic support member 42 and the mounting portion 411 and the matching structure of the lower end of the elastic support member 42 and the shell 1 are not limited to the above-described implementation mode. In simple terms, it can also be directly connected to the shell 1 or the mounting portion 411 through the spring 423, which can meet the requirements of stable connection and provide elastic support to the matching structure of the crankcase 3 and the motor 2. In this embodiment, the elastic support member 42 is configured so 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 in the above structure.

[0057] Specifically, the sum of the height of the first bushing 422 and the height of the second bushing 425 is greater than the height of the lower end surface of the support plate 41 from the lower end surface of the motor 2. Since the elastic support member 42 is located on the side of the motor 2, in order to avoid the motor 2 colliding with the housing 1 when the elastic support member 42 is vibrated and compressed, in this embodiment, the sum of the height of the first bushing 422 and the second bushing 425 in the elastic support member 42 is set to be greater than the height of the lower end surface of the support plate 41 from the lower end surface of the motor 2, that is, when the spring 423 in the elastic support member 42 is compressed to the point where the first bushing 422 and the second bushing 425 abut against each other, the height of the lower end surface of the motor 2 is still higher than the bottom of the first bushing 422, meeting the above structural requirements.

[0058] Also, see Figure 6 to Figure 7, the second support column 424 is integrally provided with the support plate 41. It is understandable that the second support column 424 is used to be fixed to the mounting portion 411 as described above, that is, the manner in which the second support column 424 is fixed to the mounting portion 411 may not be limited, including but not limited to using a matching structure for fixing, using an adhesive structure for bonding, using a welding structure for welding, etc., as long as the second support column 424 can be stably connected to the mounting portion 411, and in this embodiment, the second support column 424 is integrally formed with the mounting portion 411, on the one hand, reducing the process steps to reduce the production and manufacturing costs, and on the other hand, its structural stability is stronger, and the stronger the connection strength is, the structural strength requirements are met. It should be noted here that the manner in which the first support column 421 is fixed to the housing 1 may not be limited, and in this embodiment, the first support column 421 is integrally formed with the housing 1, so as to also reduce the process steps to reduce the production and manufacturing costs, and its structural stability is stronger, the connection strength is stronger, and the structural strength requirements are met.
