For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0040] The invention provides an exhaust check assembly, a stator assembly and a compressor for reducing the noise of the compressor during exhaust.

[0041] Combine the following Figures 1 to 8 The technical solution provided by the present invention is described in more detail.

[0042] The present invention provides an exhaust check assembly, which includes an exhaust valve seat 100 and an exhaust valve body 200. The exhaust valve seat 100 is arranged on an exhaust port 301. An air guide hole 110 is arranged at the bottom of the exhaust valve seat 100. The air guide hole 110 is connected to the exhaust port 301 to discharge the high-temperature gas at the exhaust port 301.

[0043] The exhaust valve body 200 is arranged in the exhaust valve seat 100, and an energy storage component is arranged between the exhaust valve body 200 and the exhaust valve seat 100. The energy storage component is used to store mechanical energy or medium energy when the exhaust valve body 200 is exhausted. After the exhaust valve body 200 is exhausted, the exhaust valve body 200 and / or the exhaust valve seat 100 are closed under the action of mechanical energy or medium energy.

[0044] The exhaust check assembly provided by the present invention comprises an exhaust valve seat 100, an exhaust valve body 200 and an energy storage assembly, wherein the energy storage assembly is arranged between the exhaust valve seat 100 and the exhaust valve body 200, and the exhaust valve body 200 is provided with an air outlet channel, the air outlet channel is used to discharge the high-temperature gas from the exhaust port 301, and the energy storage assembly is used to store mechanical energy or dielectric energy when the exhaust valve body 200 is exhausted, and after the exhaust valve body 200 is exhausted, the exhaust valve body 200 and / or the air outlet channel on the exhaust valve seat 100 are closed under the action of mechanical energy or dielectric energy. Since the energy storage assembly stores mechanical energy or dielectric energy when the exhaust valve body 200 is exhausted, the stored mechanical energy or dielectric energy can reduce the rigid contact between the exhaust valve body 200 and the exhaust valve seat 100, thereby effectively reducing the noise of the exhaust check assembly during exhaust.

[0045] In some embodiments of the present invention, the exhaust valve body 200 is a cylindrical structure, an annular base 201 is provided on the peripheral wall of the exhaust valve body 200 near the opening side, and the air outlet channel is an air outlet 202 provided in the middle of the peripheral wall of the exhaust valve body 200.

[0046] In some of the above-mentioned embodiments of the present invention, the exhaust valve body 200 is a cylindrical structure. When the exhaust valve body 200 with a cylindrical structure needs to move, the movement is more stable, reliable, and not easy to deform, thereby solving the noise problem existing in the prior art when the circular thin valve sheet moves.

[0047] An air outlet 202 is provided on the peripheral wall of the exhaust valve body 200. When the compressor exhaust port 301 is exhausted, the high-pressure refrigerant airflow is discharged through the air outlet 202 on the peripheral wall of the exhaust valve body 200, so that the energy storage component can store mechanical energy or medium energy, so that after the exhaust valve body 200 is exhausted, the stored mechanical energy or medium energy can reduce the rigid contact between the exhaust valve body 200 and the exhaust valve seat 100.

[0048] An annular base 201 is provided on the peripheral wall of the exhaust valve body 200 near the opening side. When the exhaust valve body 200 of the cylindrical structure needs to move, the annular base 201 can limit the distance that the exhaust valve body 200 moves upward, and can also ensure that when the compressor stops exhausting, the exhaust valve body 200 can return to the initial position under the action of the pressure difference. When the exhaust valve body 200 needs to be fixed, the exhaust valve body 200 can be positioned by the annular base 201.

[0049] In some embodiments of the present invention, the energy storage assembly includes an energy storage chamber 203 , which is connected to the exhaust port 301 when the exhaust valve body 200 is exhausted, and is used to store high-pressure gas exhausted from the exhaust port 301 .

[0050] In some of the above-mentioned embodiments of the present invention, the energy storage chamber 203 is arranged between the exhaust valve body 200 and the base. The energy storage chamber 203 can store the high-temperature gas discharged from the exhaust port 301. The high-temperature gas can store mechanical energy or dielectric energy when the compressor is exhausted. After the exhaust is completed, the mechanical energy or dielectric energy stored in the energy storage chamber 203 can realize the closure of the air outlet channel, thereby preventing external gas from entering the exhaust port 301.

[0051] In some embodiments of the present invention, the exhaust valve seat 100 includes an exhaust seat body 101 and a limit stop ring 102, the exhaust seat body 101 is provided with a sinking groove 103, the exhaust valve body 200 is disposed in the sinking groove 103, and can be lifted and moved in the sinking groove 103;

[0052] The limit stop ring 102 is arranged on the opening side of the sunken groove 103 and on the moving path of the annular base 201. The inner diameter of the limit stop ring 102 matches the outer diameter of the exhaust valve body 200. The energy storage chamber 203 is arranged between the limit stop ring 102 and the base.

[0053] In some of the above embodiments of the present invention, the exhaust valve seat 100 includes an exhaust seat body 101 and a limit stop ring 102, the exhaust valve body 200 is arranged in the sinking groove 103, and can move up and down in the sinking groove 103; the limit stop ring 102 is arranged on the opening side of the sinking groove 103, and is arranged on the moving path of the annular base 201, so that the exhaust valve body 200 can move up and down between the bottom of the sinking groove 103 and the limit stop ring 102, and the energy storage chamber 203 is arranged between the limit stop ring 102 and the base. When the compressor exhaust port 301 is exhausted, under the action of the high-pressure refrigerant airflow, the exhaust valve body 200 and the limit stop ring 102 can be driven to move closer to each other, and finally discharged through the outlet 202; because the exhaust valve body 200 and the limit stop ring 102 are initially in a state of moving away from each other, while the high-pressure refrigerant is discharged, the energy storage chamber 20 3 can store high-temperature gas. As the exhaust valve body 200 and the limit stop ring 102 move closer to each other, the high-temperature gas in the energy storage chamber 203 is compressed, and the high-temperature gas can drive the exhaust valve body 200 away from the exhaust valve seat 100, thereby reducing the rigid contact between the exhaust valve body 200 and the exhaust valve seat 100; as the exhaust valve body 200 and the limit stop ring 102 continue to approach each other, the gas outlet 202 moves to above the limit stop ring 102, and the gas outlet 202 can discharge high-pressure refrigerant to the outside of the exhaust valve seat 100; when the exhaust is completed, since the exhaust valve body 200 and the limit stop ring 102 are in a state of approaching each other at this time, the high-temperature gas compressed in the energy storage chamber 203 can continue to drive the exhaust valve body 200 and the limit stop ring 102 away from each other, thereby driving the exhaust valve body 200 back to the sinking groove 103, preventing external gas from entering the exhaust port 301.

[0054] In some embodiments of the present invention, the distance between the bottom surface of the limit stop ring 102 and the bottom of the air outlet 202 is H1, the distance between the top surface of the limit stop ring 102 and the top of the air outlet 202 is H2, and the distance between the top surface of the exhaust valve seat 100 and the bottom of the limit stop ring 102 is H3, wherein: H3>H2>H1.

[0055] In some of the above embodiments of the present invention, when the compressor is exhausted, the high-pressure refrigerant airflow is discharged from the exhaust port 301, causing the exhaust valve body 200 to move upward. In this process, the high-pressure airflow first enters the annular space above the annular base 201 and below the limit stop ring 102 through the air outlet 202 of the exhaust valve body 200. After the exhaust valve body 200 moves upward a distance of H1, the air outlet 202 of the exhaust valve body 200 is completely wrapped by the limit stop ring 102.

[0056] When the exhaust valve body 200 continues to move upward by a distance of H2-H1, the annular space above the annular base 201 of the exhaust valve body 200 and below the limit retaining ring 102 becomes a closed space that is constantly compressed, and the pressure of the high-pressure gas previously filled therein further increases. Since the upper cover area of ​​the exhaust valve body 200 is much larger than the annular area here, the higher-pressure gas in the annular space will only delay the upward movement of the exhaust valve body 200, so that the exhaust valve body 200 is free from impact with the limit retaining ring 102, thereby reducing the rigid contact between the exhaust valve body 200 and the limit retaining ring 102.

[0057] When the exhaust valve body 200 moves upward by a distance of H2, the gas outlet 202 of the exhaust valve body 200 begins to break away from the wrapping of the limit stop ring 102, and the high-pressure airflow is discharged from the exhaust valve body 200. When the exhaust is completed, the exhaust valve body 200 is quickly reset under the action of the high-pressure gas in the annular space above the annular base 201 and below the limit stop ring 102, preventing external gas from entering the exhaust port 301.

[0058] In some embodiments of the present invention, the energy storage assembly further includes a check valve block 104, the exhaust valve body 200 is fixedly disposed on the exhaust valve seat 100, and the check valve block 104 is movably disposed in the exhaust valve seat 100;

[0059] The check valve block 104 can move toward the exhaust valve body 200 to block the gas outlet 202 , or move away from the exhaust valve body 200 to open the gas outlet 202 . The energy storage chamber 203 is disposed between the check valve block 104 and the exhaust valve seat 100 .

[0060] In some of the above-mentioned embodiments of the present invention, the energy storage component also includes a check valve block 104, and the check valve block 104 can move close to the exhaust valve body 200 to block the air outlet 202; or move away from the exhaust valve body 200 to open the air outlet 202. The energy storage chamber 203 is arranged between the check valve block 104 and the exhaust valve seat 100, so that mechanical energy or medium energy can be stored through the energy storage chamber 203 when the exhaust valve body 200 is exhausted. After the exhaust valve body 200 is exhausted, the check valve block 104 is driven to move close to the exhaust valve body 200 under the action of mechanical energy or medium energy, thereby closing the air outlet 202 of the exhaust valve body 200.

[0061] In some embodiments of the present invention, the check valve block 104 is provided with an air flow channel 105 connected to the energy storage chamber 203 , and the exhaust valve body 200 is provided with an air vent 106 , and the air vent 106 connects the air flow channel 105 and the exhaust port 301 .

[0062] In some of the above embodiments of the present invention, the check valve block 104 is provided with an air flow channel 105 connected to the energy storage chamber 203, and the exhaust valve body 200 is provided with an air vent 106, and the air vent 106 connects the air flow channel 105 and the exhaust port 301. When the compressor is exhausted, the high-pressure refrigerant airflow is discharged from the exhaust port 301, and a part of the high-pressure gas discharged from the exhaust port 301 will pass through the air vent 106 and the air flow channel 105 into the energy storage chamber 203, and the high-pressure gas will also be discharged through the outlet 202 on the exhaust valve body 200, thereby pushing the check valve Block 104 is away from the air outlet 202. When the check valve block 104 is away from the air outlet 202, the connection between the vent 106 and the air flow channel 105 is interrupted, and the high-pressure gas stored in the energy storage chamber 203 will be compressed by the check valve block 104, thereby avoiding rigid contact between the check valve block 104 and the exhaust valve seat 100 and reducing noise during exhaust; and when the exhaust is completed, the compressed high-pressure gas stored in the storage chamber will drive the check valve plate to move toward the air outlet 202, thereby closing the air outlet 202 and preventing external gas from entering the exhaust port 301.

[0063] In some specific embodiments of the present invention, a sliding groove 107 is provided on the exhaust valve seat 100, a sliding guide column 108 is provided on the check valve block 104, the sliding guide column 108 cooperates with the sliding groove 107, and the energy storage chamber 203 is arranged between the sliding guide column 108 and the bottom of the sliding groove 107.

[0064] In some embodiments of the present invention, the check valve block 104 is provided with an arc surface 109 , and the arc surface 109 is adapted to the outer wall of the exhaust valve body 200 .

[0065] In some of the above-mentioned embodiments of the present invention, by setting a curved surface 109 on the check valve block 104, the curved surface 109 is adapted to the outer wall of the exhaust valve body 200, thereby ensuring the coordination effect between the check valve block 104 and the air outlet 202, preventing external gas from entering the exhaust port 301 from the air outlet 202, and ensuring the smooth operation of the compressor.

[0066] In some embodiments of the present invention, at least two groups of the air outlets 202 are provided, and the at least two groups of the air outlets 202 are distributed in a ring array.

[0067] In some of the above embodiments of the present invention, at least two groups of air outlets 202 are distributed in a ring array, which can ensure that the exhaust port 301 exhausts air smoothly and evenly, and ensures that the compressor runs smoothly.

[0068] It can be understood that when two groups of air outlets 202 are provided, the two groups of air outlets 202 are arranged opposite to each other, and when four groups of air outlets 202 are provided, the four groups of air outlets 202 are arranged opposite to each other and vertically.

[0069] In some embodiments of the present invention, an elastic member is further provided in the energy storage chamber 203, and mechanical energy is stored by compression of the elastic member, thereby reducing noise.

[0070] In some embodiments of the present invention, the energy storage component is an elastic member. The elastic member is arranged between the limit stop ring 102 and the annular base 201 to play a buffering and resetting role; or the elastic member is arranged between the check valve block 104 and the base to play a buffering and resetting role.

[0071] The present invention also provides a static disk assembly, comprising the exhaust check assembly as described above.

[0072] The present invention also provides a compressor, comprising the stator plate assembly as described above.

[0073] Embodiment 1:

[0074] The present invention provides a static disk assembly, including a static disk body 300 and an exhaust valve body 200. The static disk body 300 is provided with an exhaust port 301. The static disk body 300 is also provided with a sunken groove 103 above the exhaust hole. The exhaust valve body 200 is arranged in the sunken groove 103 and can be raised and lowered in the sunken groove 103.

[0075] The exhaust valve body 200 is a cylindrical structure. An annular base 201 is arranged on the peripheral wall of the exhaust valve body 200 near the opening side. Two air outlets 202 are symmetrically arranged in the middle of the peripheral wall of the exhaust valve body 200.

[0076] A limit stop ring 102 is provided on the opening side of the sunken groove 103. The limit stop ring 102 is located on the moving path of the annular base 201. The inner diameter of the limit stop ring 102 matches the outer diameter of the exhaust valve body 200. An energy storage chamber 203 is provided between the limit stop ring 102 and the base.

[0077] The distance between the bottom surface of the limit stop ring 102 and the bottom of the gas outlet 202 is H1, the distance between the top surface of the limit stop ring 102 and the top of the gas outlet 202 is H2, and the distance between the top surface of the exhaust valve seat 100 and the bottom of the limit stop ring 102 is H3, wherein: H3>H2>H1.

[0078] When the compressor is exhausted, the high-pressure refrigerant airflow is discharged from the exhaust port 301, causing the exhaust valve body 200 to move upward. In this process, the high-pressure airflow first enters the annular space above the annular base 201 and below the limit stop ring 102 through the air outlet 202 of the exhaust valve body 200. After the exhaust valve body 200 moves upward a distance of H1, the air outlet 202 of the exhaust valve body 200 is completely wrapped by the limit stop ring 102.

[0079] When the exhaust valve body 200 continues to move upward by a distance of H2-H1, the annular space above the annular base 201 of the exhaust valve body 200 and below the limit retaining ring 102 becomes a closed space that is constantly compressed, and the pressure of the high-pressure gas previously filled therein further increases. Since the upper cover area of ​​the exhaust valve body 200 is much larger than the annular area here, the higher-pressure gas in the annular space will only delay the upward movement of the exhaust valve body 200, so that the exhaust valve body 200 is free from impact with the limit retaining ring 102, thereby reducing the rigid contact between the exhaust valve body 200 and the limit retaining ring 102.

[0080] When the exhaust valve body 200 moves upward by a distance of H2, the gas outlet 202 of the exhaust valve body 200 begins to break away from the wrapping of the limit stop ring 102, and the high-pressure airflow is discharged from the exhaust valve body 200. When the exhaust is completed, the exhaust valve body 200 is quickly reset under the action of the high-pressure gas in the annular space above the annular base 201 and below the limit stop ring 102, preventing external gas from entering the exhaust port 301.

[0081] Embodiment 2:

[0082] The difference between this embodiment 2 and embodiment 1 is that the exhaust valve body 200 is fixedly arranged on the static disk body 300, and a check valve block 104 is arranged in the exhaust direction of the two exhaust ports 202, and an arc surface 109 is arranged on the check valve block 104, and the arc surface 109 is adapted to the outer wall of the exhaust valve body 200.

[0083] The check valve block 104 is movably disposed on the static disk body 300 , so that the check valve block 104 can move closer to the exhaust valve body 200 to block the air outlet 202 , or move away from the exhaust valve body 200 to open the air outlet 202 .

[0084] The static disk body 300 is provided with a sliding groove 107 , the check valve block 104 is provided with a sliding guide post 108 , the sliding guide post 108 cooperates with the sliding groove 107 , and an energy storage chamber 203 is provided between the sliding guide post 108 and the bottom of the sliding groove 107 .

[0085] Furthermore, an air flow channel 105 communicating with the energy storage chamber 203 is provided on the check valve block 104 , and an air vent 106 is provided on the annular base 201 , and the air vent 106 communicates with the air flow channel 105 and the exhaust port 301 .

[0086] When the compressor is exhausting, the high-pressure refrigerant air flow is discharged from the exhaust port 301. A part of the high-pressure gas discharged from the exhaust port 301 will enter the energy storage chamber 203 through the air vent 106 and the air flow channel 105, and the high-pressure gas will also be discharged through the air outlet 202 on the exhaust valve body 200, thereby pushing the check valve block 104 away from the air outlet 202. When the check valve block 104 is away from the air outlet 202, the connection between the air vent 106 and the air flow channel 105 is interrupted, and the high-pressure gas stored in the energy storage chamber 203 will be compressed by the check valve block 104, thereby avoiding rigid contact between the check valve block 104 and the exhaust valve seat 100, reducing noise during exhaust; and when the exhaust is completed, the compressed high-pressure gas stored in the storage chamber will drive the check valve plate to move toward the air outlet 202, thereby closing the air outlet 202 and preventing external gas from entering the exhaust port 301.
