The compressor is the core component of the air conditioner, and the operating efficiency and reliability of the compressor are factors that need to be considered in the production and manufacturing of the compressor.

[0003] The compressor contains a pump assembly. During operation, the crankshaft inside the pump assembly rotates relative to the cylinder, allowing outside gas to enter the compression chamber for compression. However, in existing compressors, the compression chamber is under excessively low pressure or vacuum before intake begins. This causes gas in the compression chamber to flow back through the intake port during initial operation, reducing the actual intake volume and affecting the compressor's operating efficiency. Furthermore, when the compression chamber is under excessively low pressure or vacuum, the stress on various structures within the compressor increases, affecting the compressor's operational reliability and lifespan, indicating room for improvement.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] The following is for reference. Figures 1-7 The pump body assembly described in this embodiment of the invention has a simple structure, low installation cost, and can eliminate the closed volume of the pump body assembly, reduce gas backflow, improve operating efficiency, ensure the operational reliability of the pump body assembly, and extend the service life of the pump body assembly.

[0046] like Figures 1-7 As shown, a pump body assembly according to an embodiment of the present invention includes: a crankshaft, a first bearing, a cylinder 100, and a second bearing.

[0047] The crankshaft is sequentially mounted on the first bearing, the cylinder 100, and the second bearing. A compression chamber 1 is formed inside the cylinder 100. The inner wall of the cylinder 100 is provided with a vane groove 2 and an intake hole 3. The vane groove 2 and the intake hole 3 are respectively connected to the compression chamber 1. A connecting channel 5 connected to the intake hole 3 is also formed inside the cylinder 100. At least one of the first bearing and the second bearing defines a connecting cavity 6 between itself and the cylinder 100. The connecting cavity 6 is connected to the intake hole 3, and both the vane groove 2 and the compression chamber 1 are connected to the connecting cavity 6.

[0048] The pump assembly is located inside the compressor, which is a driven fluid machine that raises low-pressure gas to high-pressure gas; it is the heart of an air conditioner or refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it using a piston driven by a motor, and then discharges high-temperature, high-pressure refrigerant gas through the exhaust pipe, providing power for the refrigeration cycle.

[0049] Specifically, the pump body assembly includes a first bearing, a cylinder 100, and a second bearing. The cylinder 100 has a cylindrical structure. The first and second bearings are located at both ends of the cylinder 100. Specifically, the first bearing can be configured as the upper bearing, and the second bearing can be configured as the lower bearing, with the first and second bearings respectively installed at the upper and lower ends of the cylinder 100. Alternatively, the first bearing can be configured as the lower bearing, and the second bearing can be configured as the upper bearing, with the second and first bearings respectively installed at the upper and lower ends of the cylinder 100. This configuration offers high flexibility. The pump body assembly also includes a crankshaft, which can be sequentially inserted through the first bearing, the cylinder 100, and the second bearing. The crankshaft can be driven by a drive motor to rotate relative to the first bearing, the cylinder 100, and the second bearing. The first and second bearings support the crankshaft, ensuring reliable operation.

[0050] Furthermore, a compression chamber 1 is formed inside the cylinder 100, and the inner wall of the cylinder 100 is provided with a vane groove 2, an intake port 3, and an exhaust port 4. The intake port 3 and the exhaust port 4 can be respectively set on both sides of the vane groove 2 along the circumference of the cylinder 100, and the vane groove 2, the intake port 3, and the exhaust port 4 can all communicate with the compression chamber 1. A piston is provided in the compression chamber 1, and the piston is sleeved on the eccentric part of the crankshaft located in the compression chamber 1. The piston can roll along the inner wall of the compression chamber 1. A vane is provided in the vane groove 2, and the vane can move relative to the vane groove 2. The end of the vane away from the piston can be pressed against the vane by a structure such as a spring, so that the end of the vane near the piston can stop against the outer peripheral wall of the piston. When the compressor is working, the piston sleeved outside the eccentric part of the crankshaft can roll along the inner wall of the compression chamber 1, thereby compressing the gas that enters the compression chamber 1 through the intake port 3. The compressed gas can be discharged from the exhaust port 4 to complete one operation of the pump assembly.

[0051] In this configuration, at least one of the first bearing and the second bearing defines a connecting cavity 6 between the first bearing and the cylinder 100. The connecting cavity 6 can be defined only between the first bearing and the cylinder 100, only between the second bearing and the cylinder 100, or both between the first bearing and the cylinder 100 and between the second bearing and the cylinder 100, allowing for flexible configuration.

[0052] Furthermore, the cylinder 100 also forms a connecting channel 5. One end of the connecting channel 5 can be connected to the air intake port 3, and the other end of the connecting channel 5 can be connected to the connecting cavity 6, so that the connecting channel 5 can be connected to the air intake port 3. That is, gas can enter the compression cavity 1 through the air intake port 3, and during the process of gas flowing to the compression cavity 1, some gas can flow to the connecting cavity 6 through the connecting channel 5.

[0053] Furthermore, both the vane groove 2 and the compression chamber 1 are connected to the connecting chamber 6, allowing gas to enter the connecting chamber 6 through the suction port 3 and then flow through the connecting chamber 6 to the vane groove 2 and the compression chamber 1. This eliminates the closed volume of the pump assembly, forming a connected cavity with the suction port 3, connecting channel 5, connecting chamber 6, vane groove 2, and compression chamber 1. When the pump assembly is initially running, the piston rolls along the inner wall of the compression chamber 1 to compress the gas entering the compression chamber 1 through the suction port 3. At this time, some gas can enter the compression chamber 1 and the vane groove 2 through the connecting chamber 6, thus preventing the compression chamber 1 from being in an excessively low-pressure or vacuum state, reducing the stress on each structure, ensuring the operational reliability of the pump assembly, extending the service life of the pump assembly, and having a simple structure and low installation cost. It also reduces gas backflow in the compression chamber 1, ensuring the actual suction volume and thus ensuring operating efficiency.

[0054] In actual setup, the connecting cavity 6 can be connected only to the vane groove 2, only to the compression cavity 1, or both the vane groove 2 and the compression cavity 1, even if the pump body assembly has a non-enclosed volume, thus improving the flexibility of the setup.

[0055] According to the embodiments of the present invention, the pump body assembly is provided with a connecting cavity 6 that communicates with the suction port 3, and the vane groove 2 and the compression chamber 1 are both connected to the connecting cavity 6. This eliminates the closed volume of the pump body assembly, avoids excessively low pressure or vacuum in the compression chamber 1, reduces the stress on each structure, ensures the operational reliability of the pump body assembly, extends the service life of the pump body assembly, has a simple structure, low installation cost, and can reduce gas backflow in the compression chamber 1, ensuring the actual suction volume, thereby ensuring operating efficiency, better performance, and wider applicability.

[0056] In some embodiments, the communicating cavity 6 includes a first communicating region 61, the first communicating region 61 having a first communicating side 611 and a second communicating side 612, the first communicating side 611 communicating with the compression cavity 1, and the second communicating side 612 communicating with the sliding plate groove 2.

[0057] Specifically, at least one of the first and second bearings defines a communicating cavity 6 between itself and the cylinder 100. A communicating channel 5 connects the intake port 3 and the communicating cavity 6 to eliminate the enclosed volume of the pump body assembly, and as... Figures 1-4 As shown, the connecting cavity 6 is provided with a first connecting region 61. The first connecting region 61 can be configured as a fan shape, rectangle or triangle, etc., and the first connecting region 61 has a first connecting side 611 and a second connecting side 612. The first connecting side 611 is configured to communicate with the compression cavity 1, and the second connecting side 612 is configured to communicate with the sliding plate groove 2, so that the connecting cavity 6 can communicate with both the compression cavity 1 and the sliding plate groove 2 at the same time.

[0058] Furthermore, such as Figures 1-4As shown, in this embodiment, the first connecting region 61 is configured as a fan shape, and the two radii of the fan shape are the first connecting side 611 and the second connecting side 612. The first connecting side 611 is open to the compression chamber 1, so that the connecting channel 5 can be connected to the compression chamber 1 through the connecting cavity 6, thereby ensuring the operational reliability of the piston and other structures. The second connecting side 612 is open to the sliding vane groove 2, so that the connecting channel 5 can be connected to the sliding vane groove 2 through the connecting cavity 6, thereby ensuring the operational reliability of the sliding vane and other structures. Furthermore, by connecting both sides of the connecting cavity 6 to the compression chamber 1 and the sliding vane groove 2 respectively, only one connecting cavity 6 needs to be set at one end of the cylinder 100, reducing the setting cost and ensuring the structural strength of the cylinder 100.

[0059] In some embodiments, the communicating cavity 6 further includes a second communicating region 62, which is connected to the first communicating region 61 via a transition channel 63 and is connected to the communicating channel 5.

[0060] Specifically, such as Figure 1 and Figure 3 As shown, the connecting cavity 6 is also provided with a second connecting region 62 and a transition channel 63. The second connecting region 62 is connected to the connecting channel 5, that is, one end of the connecting channel 5 is connected to the suction hole 3, and the other end of the connecting channel 5 is connected to the second connecting region 62, so that the gas flowing from the suction hole 3 to the connecting channel 5 can first flow into the second connecting region 62. One end of the transition channel 63 is connected to the second connecting region 62, and the other end of the transition channel 63 is connected to the first connecting region 61, so that the gas in the second connecting region 62 can flow through the transition channel 63 to the first connecting region 61, and then flow into the compression cavity 1 and the sliding vane groove 2.

[0061] Furthermore, the second connecting region 62 can be configured as a circular region or a rounded rectangular region, etc. When the gas flows from the connecting channel 5 into the second connecting region 62, it can be buffered by the second connecting region 62. When the second connecting region 62 is configured as a circular region or a rounded rectangular region, the energy loss of the gas in the second connecting region 62 can be reduced, thereby reducing the energy consumption of the pump assembly and ensuring the operating efficiency of the pump assembly.

[0062] In some embodiments, the width of the first connected region 61 and the width of the second connected region 62 are both greater than the width of the transition channel 63.

[0063] Specifically, the transition channel 63 connects the first connecting region 61 and the second connecting region 62, allowing the gas in the suction port 3 to flow through the connecting channel 5 to the second connecting region 62, and then through the transition channel 63 to the first connecting region 61, so that it can flow through the first connecting region 61 to the compression chamber 1 and the sliding vane groove 2 respectively. Figure 1 and Figure 3As shown, the width of the first connected region 61 can be set to be greater than the width of the transition channel 63, and the width of the second connected region 62 can also be set to be greater than the width of the transition channel 63, so that the amount of gas contained in the first connected region 61 and the second connected region 62 is greater than the amount of gas contained in the transition channel 63.

[0064] Furthermore, when the gas enters the second connecting region 62, the second connecting region 62 can buffer the gas. When the gas enters the transition channel 63, since the width of the transition channel 63 is smaller than the width of the second connecting region 62, the gas flow rate can be increased to improve the rate at which the gas enters the first connecting region 61. The width of the first connecting region 61 is set to be greater than the width of the transition channel 63, which can improve the speed at which the first connecting region 61 delivers gas to the compression chamber 1 and the vane groove 2, and ensure the reliability of the amount of gas delivered by the first connecting region 61 to the compression chamber 1 and the vane groove 2.

[0065] In some embodiments, the connecting cavity 6 further includes an intermediate channel 64, one end of which is connected to the first connecting region 61, and the other end of which is connected to the connecting channel 5. The width of the first connecting region 61 is greater than the width of the intermediate channel 64.

[0066] Specifically, at least one of the first and second bearings defines a communicating cavity 6 between itself and the cylinder 100. A communicating channel 5 connects the intake port 3 and the communicating cavity 6 to eliminate the enclosed volume of the pump body assembly, and as... Figure 2 and Figure 4 As shown, the connecting cavity 6 also includes an intermediate channel 64. One end of the intermediate channel 64 can be connected to the first connecting region 61, and the other end of the intermediate channel 64 can be connected to the connecting channel 5, so that gas can flow from the connecting channel 5 to the intermediate channel 64, and then directly flow into the first connecting region 61 through the intermediate channel 64, so that the first connecting region 61 can deliver gas to the compression cavity 1 and the sliding vane groove 2 respectively, thereby increasing the speed at which the first connecting region 61 delivers gas to the compression cavity 1 and the sliding vane groove 2.

[0067] In addition, the width of the first connecting region 61 is set to be greater than the width of the intermediate channel 64, so that the first connecting region 61 can accommodate a larger amount of gas, which can ensure the reliability of the gas supply from the first connecting region 61 to the compression chamber 1 and the sliding vane groove 2.

[0068] And in actual settings, such as Figures 5-7 As shown, the connecting cavity 6 can be configured as a straight channel, with one end of the straight channel connected to the connecting channel 5, and the other end of the straight channel can be configured as follows: Figure 5 As shown, it is connected to the compression chamber 1 and the sliding vane groove 2, and can also be used as follows: Figures 6-7 As shown, it is only connected to compression chamber 1, and depending on the amount of gas compression by the pump assembly, the straight channel can also be as shown. Figures 6-7 The settings shown are for different widths, offering high flexibility to meet various usage needs.

[0069] In some embodiments, the communication width between the first communication side 611 and the compression cavity 1 is greater than or equal to the communication width between the second communication side 612 and the sliding groove 2.

[0070] Specifically, the first connecting region 61 has a first connecting side 611 and a second connecting side 612. The first connecting side 611 is configured to communicate with the compression chamber 1, and the second connecting side 612 is configured to communicate with the sliding vane groove 2. The communication width between the first connecting side 611 and the compression chamber 1 is set to be greater than or equal to the communication width between the second connecting side 612 and the sliding vane groove 2. That is, the communication width between the first connecting side 611 and the compression chamber 1 can be set to be equal to the communication width between the second connecting side 612 and the sliding vane groove 2, or it can be set to be greater than the communication width between the second connecting side 612 and the sliding vane groove 2.

[0071] Furthermore, such as Figures 1-4 As shown, the larger the connection width between the first connecting side 611 and the compression chamber 1, and between the second connecting side 612 and the vane groove 2, the greater the amount of gas delivered from the connecting chamber 6 to the compression chamber 1 or the vane groove 2 per unit time. Since the compression chamber 1 is used to accommodate structures such as the piston and crankshaft, and the vane groove 2 only needs to accommodate the vane, the volume of the compression chamber 1 is set to be greater than the volume of the vane groove 2. Setting the connection width between the first connecting side 611 and the compression chamber 1 to be greater than or equal to the connection width between the second connecting side 612 and the vane groove 2 can ensure that the amount of gas delivered to the compression chamber 1 and the vane groove 2 is sufficient. This can reduce the stress on the crankshaft, piston, and vane structures during pump body operation, extend the service life of the crankshaft, piston, and vane structures, and ensure the reliability of pump body operation.

[0072] In some embodiments, the first communication side 611 is configured to communicate radially with the compression chamber 1 along the cylinder 100; and / or, the second communication side 612 is configured to communicate circumferentially with the vane groove 2 along the cylinder 100.

[0073] Specifically, the first connecting side 611 is configured to connect radially to the compression chamber 1 along the cylinder 100, and / or the second connecting side 612 is configured to connect circumferentially to the sliding vane groove 2 along the cylinder 100. It is possible to configure only the first connecting side 611 to connect radially to the compression chamber 1 along the cylinder 100, or only the second connecting side 612 to connect circumferentially to the sliding vane groove 2 along the cylinder 100. Alternatively, the first connecting side 611 can be configured to connect radially to the compression chamber 1 along the cylinder 100, while the second connecting side 612 can be configured to connect circumferentially to the sliding vane groove 2 along the cylinder 100.

[0074] Furthermore, the compression chamber 1 is located in the middle of the cylinder 100 and extends through the cylinder 100 along its axial direction. The suction port 3 extends radially through the cylinder 100, and one end of the suction port 3 facing the interior of the cylinder 100 communicates with the compression chamber 1. The sliding vane groove 2 extends through the cylinder 100 along its axial direction and extends radially through the cylinder 100. One end of the sliding vane groove 2 facing the interior of the cylinder 100 communicates with the compression chamber 1. In this embodiment, as shown... Figures 1-4 As shown, the first connecting side 611 is configured to connect with the compression chamber 1 radially along the cylinder 100, while the second connecting side 612 is configured to connect with the sliding vane groove 2 circumferentially along the cylinder 100. This ensures that while providing a connecting chamber 6, the amount of gas delivered by the connecting chamber 6 to the compression chamber 1 and the sliding vane groove 2 can be maximized, thereby ensuring the reliability of the connecting chamber 6.

[0075] In some embodiments, the first connecting region 61 connects to the junction of the sliding vane groove 2 and the compression chamber 1.

[0076] Specifically, the vane groove 2 extends radially along the cylinder 100, and one end of the vane groove 2 facing the inside of the cylinder 100 communicates with the compression chamber 1, that is, the vane groove 2 and the compression chamber 1 have a connection point, such as... Figures 1-4 As shown, the first connecting region 61 can be connected to the connection between the vane groove 2 and the compression chamber 1, so that gas can be delivered to the compression chamber 1 and the vane groove 2 respectively through the first connecting region 61. This reduces the number of connecting chambers 6, lowers the installation cost, and ensures the structural strength of the cylinder 100, thereby ensuring the service life and reliability of the pump body assembly.

[0077] In some embodiments, the end face of the first bearing facing the cylinder 100 is provided with a first bearing groove, and / or the end face of the cylinder 100 facing the first bearing is provided with a first cylinder groove, wherein the first bearing and the cylinder 100 define a communicating cavity 6 at the first bearing groove and / or the first cylinder groove.

[0078] Specifically, the end face of the first bearing facing the cylinder 100 is provided with a first bearing groove, and / or the end face of the cylinder 100 facing the first bearing is provided with a first cylinder groove. Alternatively, the first bearing groove may be provided only on the end face of the first bearing facing the cylinder 100, or the first cylinder groove may be provided only on the end face of the cylinder 100 facing the first bearing. It is also possible that the first bearing groove is provided on the end face of the first bearing facing the cylinder 100, and the first cylinder groove is provided on the end face of the cylinder 100 facing the first bearing.

[0079] When the first bearing groove is provided only on the end face of the first bearing facing the cylinder 100, the first bearing is installed at one end of the cylinder 100. The end face of the cylinder 100 near the first bearing can close the first bearing groove of the first bearing, so that the cylinder 100 and the first bearing groove can jointly define the communicating cavity 6. The structure is simple, and only the groove needs to be provided on the first bearing to ensure the integrity of the cylinder 100 structure and ensure the reliability of the cylinder 100.

[0080] When the first cylinder groove is provided only on the end face of the cylinder 100 facing the first bearing, the first bearing is installed at one end of the cylinder 100.

The end face of the second bearing near the cylinder 100 can close the second cylinder groove of the cylinder 100, so that the cylinder 100 and the second cylinder groove can jointly define the communicating cavity 6. The structure is simple, and only the groove needs to be provided in the cylinder 100 to ensure the integrity of the second bearing structure and ensure the reliability of the second bearing.

[0086] When a second bearing groove is provided on the end face of the second bearing facing the cylinder 100, and a second cylinder groove is provided on the end face of the cylinder 100 facing the second bearing, the second bearing is installed at one end of the cylinder 100. The second bearing groove and the second cylinder groove are correspondingly arranged so that the second bearing groove and the second cylinder groove can jointly define the connecting cavity 6. The structure is simple, and the second bearing groove and the second cylinder groove jointly define the connecting cavity 6. While ensuring the setting size of the connecting cavity 6, the groove depth of the second bearing groove and the second cylinder groove can be reduced, thereby ensuring the reliability of the second bearing and the cylinder 100.

[0087] In some embodiments, a connecting cavity 6 is formed between the first bearing and the cylinder 100 and between the second bearing and the cylinder 100, and the two connecting cavities 6 are respectively connected to the two ends of the connecting channel 5.

[0088] Specifically, a first bearing and a second bearing are respectively provided at both ends of the cylinder 100.

[0089] Furthermore, the two ends of the connecting channel 5 are respectively connected to the connecting chamber 6, and the suction hole 3 can be connected to the middle of the connecting channel 5, so that the gas in the suction hole 3 can flow through the connecting channel 5 toward the two connecting chambers 6 respectively, so as to flow through the two connecting chambers 6 toward the two ends of the compression chamber 1 along the axial direction and the two ends of the sliding vane groove 2 along the axial direction, thereby ensuring the operational reliability of each part inside the pump body assembly.

[0090] In some embodiments, a connecting cavity 6 is formed between the first bearing and the cylinder 100 and between the second bearing and the cylinder 100, and the two connecting cavities 6 are symmetrically distributed.

[0091] Specifically, a connecting cavity 6 can be defined between the first bearing and one end of the cylinder 100, and a connecting cavity 6 can also be defined between the second bearing and the other end of the cylinder 100. The two connecting cavities 6 are symmetrically distributed at both ends of the cylinder 100. The two ends of the connecting channel 5 are respectively connected to the two connecting cavities 6, and the suction hole 3 can be connected to the middle of the connecting channel 5, so that the gas in the suction hole 3 can flow through the connecting channel 5 toward the two connecting cavities 6 respectively, so as to flow through the two connecting cavities 6 toward the two ends of the compression chamber 1 along the axial direction and the two ends of the vane groove 2 along the axial direction. The two connecting cavities 6 are symmetrically arranged so that the amount of gas flowing to the two ends of the compression chamber 1 along the axial direction and the two ends of the vane groove 2 along the axial direction are the same, thereby ensuring the consistency and reliability of the operation of various parts inside the pump body assembly.

[0092] In some embodiments, the air intake 3 and the communication channel 5 are connected radially to the cylinder 100, and the communication channel 5 and the communication cavity 6 are connected axially to the cylinder 100.

[0093] Specifically, the connecting channel 5 can connect the suction port 3 and the connecting cavity 6. The connecting channel 5 is configured to extend along the axial direction of the cylinder 100, and the suction port 3 is configured to extend along the radial direction of the cylinder 100, so that one end of the connecting channel 5 along the axial direction can be connected to the suction port 3, and the other end of the connecting channel 5 along the axial direction can be connected to the connecting cavity 6. This allows the length of the connecting channel 5 along the axial direction to be set to the shortest possible value, thereby reducing the energy loss when the gas flows in the connecting channel 5.
