Description

Technical Field

[0001] This invention relates to the field of compressor technology, and in particular to an exhaust check assembly, a stationary plate assembly, and a compressor. Background Technology

[0002] The compressor is the heart of an air conditioning system, and its performance directly affects the air conditioner's energy efficiency ratio. Scroll compressors are positive displacement compressors. An electric motor drives a crankshaft to rotate, and the moving scroll revolves around a stationary scroll under the crankshaft's influence, thus achieving periodic changes in the sealed volume and compressing the gas. During operation, if the pressure on the discharge side exceeds the pressure inside the scroll chamber, refrigerant backflow can cause the compressor to reverse, generating significant noise and affecting its reliability.

[0003] The existing exhaust check structure has the following problems in actual use:

[0004] (1) In order to improve energy efficiency, the existing scroll compressor has an irregularly shaped exhaust port. The high-pressure gas discharged acts on the valve plate, and the resultant force does not pass perpendicularly through the center of mass of the existing circular thin valve plate. The valve plate overturns and deflects during the rising process, which aggravates the friction with the constraint surface of the valve seat and generates noise.

[0005] (2) The circular, thin-plate exhaust check valve plate rapidly impacts the upper part of the valve seat and the gasket during movement. In particular, when the exhaust check valve plate moves downward, only the edge area is subjected to force, which easily causes deformation. This affects the lifespan of the exhaust check valve plate and the reliability of the compressor. Summary of the Invention

[0006] The purpose of this invention is to provide an exhaust check valve assembly, a stationary disc assembly, and a compressor to solve the technical problem of noise generation by exhaust check valve plates in the prior art. 。 The preferred technical solutions among the many technical solutions provided by this invention can produce a variety of technical effects, which are described in detail below.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The exhaust check assembly provided by the present invention includes an exhaust valve seat and an exhaust valve body. The exhaust valve body is disposed within the exhaust valve seat, and an energy storage component is disposed between the exhaust valve body and the exhaust valve seat. The energy storage component is used to store mechanical energy or medium energy when the exhaust valve body exhausts. After the exhaust valve body exhausts, the exhaust valve body closes the exhaust passage on the exhaust valve body and / or the exhaust valve seat under the action of mechanical energy or medium energy.

[0009] As an optional implementation, the exhaust valve body has a cylindrical structure, and an annular base is provided on the peripheral wall of the exhaust valve body near the opening side. The exhaust passage is an exhaust port provided in the middle of the peripheral wall of the exhaust valve body.

[0010] As an optional implementation, the energy storage component includes an energy storage chamber that is connected to the exhaust port when the exhaust valve body exhausts gas, for storing the high-pressure gas discharged from the exhaust port.

[0011] As an optional implementation, the exhaust valve seat includes an exhaust seat body and a limiting retaining ring. The exhaust seat body is provided with a recessed groove, and the exhaust valve body is disposed in the recessed groove and can move up and down within the recessed groove.

[0012] The limiting ring is disposed on the opening side of the recessed groove and on the moving path of the annular base. The inner diameter of the limiting ring matches the outer diameter of the exhaust valve body. The energy storage chamber is disposed between the limiting ring and the base.

[0013] As an optional implementation, the distance between the bottom surface of the limiting ring and the bottom of the air outlet is H1, the distance between the top surface of the limiting ring and the top of the air outlet is H2, and the distance between the top surface of the exhaust valve seat and the bottom of the limiting ring is H3, wherein: H3 > H2 > H1.

[0014] As an optional implementation, the energy storage component further includes a check valve block, the exhaust valve body is fixedly mounted on the exhaust valve seat, and the check valve block is movably mounted inside the exhaust valve seat.

[0015] The check valve block can move close to the exhaust valve body to block the exhaust port; or move away from the exhaust valve body to open the exhaust port. The energy storage chamber is located between the check valve block and the exhaust valve seat.

[0016] As an optional implementation, the check valve block is provided with an airflow channel communicating with the energy storage chamber, and the exhaust valve body is provided with a vent hole, which communicates with the airflow channel and the exhaust port.

[0017] As an optional implementation, the exhaust valve seat is provided with a sliding groove, the check valve block is provided with a sliding guide post, the sliding guide post cooperates with the sliding groove, and the energy storage chamber is disposed between the sliding guide post and the bottom of the sliding groove.

[0018] As an optional implementation, the check valve block is provided with an arc-shaped surface, which is adapted to the outer wall of the exhaust valve body.

[0019] As an optional implementation, the air outlet is provided in at least two sets, and the at least two sets of air outlets are arranged in a ring array.

[0020] A static plate assembly includes the exhaust check assembly as described above.

[0021] A compressor including the stationary disc assembly as described above.

[0022] The beneficial effects of the present invention are as follows: The exhaust check assembly, stationary plate assembly, and compressor provided by the present invention include an exhaust valve seat, an exhaust valve body, and an energy storage assembly. The energy storage assembly is disposed between the exhaust valve seat and the exhaust valve body. The exhaust valve body is provided with an exhaust passage for discharging high-temperature gas from the exhaust port. The energy storage assembly is used to store mechanical energy or medium energy when the exhaust valve body discharges gas. After the exhaust valve body discharges gas, the exhaust passage of the exhaust valve body is closed under the action of mechanical energy or medium energy. Since the energy storage assembly stores mechanical energy or medium energy when the exhaust valve body discharges gas, the rigid contact between the exhaust valve body and the exhaust valve seat can be reduced through mechanical energy or medium energy, thereby effectively reducing the noise of the compressor during discharge.

[0040] This invention provides an exhaust check assembly, a stationary plate assembly, and a compressor for reducing noise during compressor exhaust.

[0041] The following is combined with Figures 1 to 8 The technical solution provided by this invention will be described in more detail below.

[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 disposed on an exhaust port 301, and an air guide hole 110 is provided at the bottom of the exhaust valve seat 100. The air guide hole 110 is connected to the exhaust port 301 to discharge high-temperature gas from the exhaust port 301.

[0043] The exhaust valve body 200 is disposed within the exhaust valve seat 100, and an energy storage component is disposed 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 exhausts. After the exhaust valve body 200 exhausts, it closes the exhaust passage on the exhaust valve body 200 and / or the exhaust valve seat 100 under the action of mechanical energy or medium energy.

[0044] The exhaust check assembly provided by the present invention includes an exhaust valve seat 100, an exhaust valve body 200, and an energy storage component. The energy storage component is disposed between the exhaust valve seat 100 and the exhaust valve body 200. The exhaust valve body 200 is provided with an exhaust channel for discharging high-temperature gas from the exhaust port 301. The energy storage component stores mechanical energy or medium energy when the exhaust valve body 200 discharges gas. After the exhaust valve body 200 discharges gas, the exhaust channel on the exhaust valve body 200 and / or the exhaust valve seat 100 is closed under the action of mechanical energy or medium energy. Since the energy storage component stores mechanical energy or medium energy when the exhaust valve body 200 discharges gas, the stored mechanical energy or medium energy can reduce 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 has a cylindrical structure, and an annular base 201 is provided on the peripheral wall of the exhaust valve body 200 near the opening side, and the exhaust channel is an exhaust port 202 provided in the middle of the peripheral wall of the exhaust valve body 200.

[0046] In some of the embodiments of the present invention described above, the exhaust valve body 200 is a cylindrical structure. When the cylindrical exhaust valve body 200 needs to move, the movement is more stable, reliable, and less prone to deformation, thereby solving the noise problem that exists when the circular thin valve plate moves in the prior art.

[0047] An outlet 202 is provided on the peripheral wall of the exhaust valve body 200. When the compressor exhaust port 301 exhausts, the high-pressure refrigerant gas flows out through the outlet 202 on the peripheral wall of the exhaust valve body 200, which enables the energy storage component to store mechanical energy or medium energy. After the exhaust valve body 200 exhausts, 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. When the cylindrical exhaust valve body 200 needs to be moved, the annular base 201 can limit the upward movement of the exhaust valve body 200, and also ensure that when the compressor stops discharging, the exhaust valve body 200 can return to its initial position under the action of pressure difference. When the exhaust valve body 200 needs to be fixed, it can be positioned by the annular base 201.

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

[0050] In some of the embodiments of the present invention described above, the energy storage chamber 203 is disposed 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 medium energy when the compressor is venting. After the venting is completed, the mechanical energy or medium energy stored in the energy storage chamber 203 can close the exhaust 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 limiting retaining ring 102. The exhaust seat body 101 is provided with a recessed groove 103. The exhaust valve body 200 is disposed in the recessed groove 103 and can move up and down within the recessed groove 103.

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

[0053] In some embodiments of the present invention described above, the exhaust valve seat 100 includes an exhaust seat body 101 and a limiting ring 102. The exhaust valve body 200 is disposed within a recessed groove 103 and can move up and down within the recessed groove 103. The limiting ring 102 is disposed on the opening side of the recessed groove 103 and on the moving path of the annular base 201, allowing the exhaust valve body 200 to move up and down between the bottom of the recessed groove 103 and the limiting ring 102. The energy storage chamber 203 is disposed between the limiting ring 102 and the base. When the compressor exhaust port 301 discharges, under the action of the high-pressure refrigerant airflow, the exhaust valve body 200 and the limiting ring 102 can be driven to move closer to each other and finally discharged through the outlet 202. Since the exhaust valve body 200 and the limiting ring 102 are initially in a state of moving away from each other, the energy storage chamber 203 moves up and down between the high-pressure refrigerant and the limiting ring 102 at the same time as the high-pressure refrigerant is discharged. 3. It can store high-temperature gas. As the exhaust valve body 200 and the limiting ring 102 move closer to each other, they compress the high-temperature gas in the energy storage chamber 203. 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 limiting ring 102 continue to move closer to each other, the outlet 202 moves above the limiting ring 102, and the outlet 202 can discharge high-pressure refrigerant to the outside of the exhaust valve seat 100. When the exhaust is finished, since the exhaust valve body 200 and the limiting ring 102 are in a close-to-each-other state, the high-temperature gas compressed in the energy storage chamber 203 can continue to drive the exhaust valve body 200 and the limiting ring 102 away from each other, thereby driving the exhaust valve body 200 back into the recessed 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 limiting ring 102 and the bottom of the air outlet 202 is H1, the distance between the top surface of the limiting 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 limiting ring 102 is H3, wherein: H3 > H2 > H1.

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

[0056] As the exhaust valve body 200 continues to move upward a distance H2-H1, the annular space above the annular base 201 and below the limiting ring 102 of the exhaust valve body 200 becomes a continuously compressed closed space, further increasing the pressure of the previously filled high-pressure gas. Since the area of ​​the upper cover of the exhaust valve body 200 is much larger than the area of ​​this annular space, the higher pressure gas in the annular space only slows down the upward movement of the exhaust valve body 200, preventing it from impacting the limiting ring 102 and thus reducing the rigid contact between the exhaust valve body 200 and the limiting ring 102.

[0057] When the exhaust valve body 200 moves upward a distance H2, the exhaust port 202 of the exhaust valve body 200 begins to disengage from the limiting ring 102, allowing the high-pressure airflow to exit the exhaust valve body 200. After exhaust is completed, the exhaust valve body 200 quickly resets under the action of high-pressure gas in the annular space above the annular base 201 and below the limiting ring 102, preventing external gas from entering the exhaust port 301.

[0058] In some embodiments of the present invention, the energy storage component 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 within the exhaust valve seat 100.

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

[0060] In some embodiments of the present invention described above, the energy storage component further includes a check valve block 104, which can move close to the exhaust valve body 200 to block the exhaust port 202; or move away from the exhaust valve body 200 to open the exhaust port 202. The energy storage chamber 203 is disposed between the check valve block 104 and the exhaust valve seat 100, thereby storing mechanical energy or medium energy when the exhaust valve body 200 exhausts. After the exhaust valve body 200 exhausts, 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 exhaust port 202 of the exhaust valve body 200.

[0061] In some embodiments of the present invention, the check valve block 104 is provided with an airflow channel 105 that communicates with the energy storage chamber 203, and the exhaust valve body 200 is provided with a vent hole 106 that communicates with the airflow channel 105 and the exhaust port 301.

[0062] In some embodiments of the present invention described above, the check valve block 104 is provided with an airflow channel 105 communicating with the energy storage chamber 203, and the exhaust valve body 200 is provided with a vent hole 106 communicating with the airflow channel 105 and the exhaust port 301. When the compressor discharges, the high-pressure refrigerant gas flows out from the exhaust port 301. Part of the high-pressure gas discharged from the exhaust port 301 enters the energy storage chamber 203 through the vent hole 106 and the airflow channel 105. The high-pressure gas also exits through the outlet 202 on the exhaust valve body 200, thereby pushing the check valve. When the check valve block 104 moves away from the air outlet 202, the connection between the vent 106 and the airflow channel 105 is interrupted. 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. After exhaust is completed, the compressed high-pressure gas stored in the storage chamber will drive the check valve plate to move towards the air outlet 202, thereby sealing the air outlet 202 and preventing external gas from entering the exhaust port 301.

[0063] In some specific embodiments of the present invention, the exhaust valve seat 100 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 the energy storage chamber 203 is disposed between the bottom of the sliding guide post 108 and the sliding groove 107.

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

[0065] In some of the embodiments of the present invention described above, by providing an arc-shaped surface 109 on the check valve block 104, the arc-shaped surface 109 is adapted to the outer wall of the exhaust valve body 200, thereby ensuring the cooperation effect between the check valve block 104 and the outlet 202, preventing external gas from entering the exhaust port 301 from the outlet 202, and ensuring the smooth operation of the compressor.

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

[0067] In some of the embodiments of the present invention described above, at least two sets of air outlets 202 are arranged in a ring array, which can ensure that the exhaust from the exhaust port 301 is stable and uniform, and ensure that the compressor operates smoothly.

[0068] It is understandable that when there are two sets of air outlets 202, the two sets of air outlets 202 are set opposite to each other, and when there are four sets of air outlets 202, the four sets of air outlets 202 are set opposite to each other and perpendicular to each other.

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

[0070] In some embodiments of the present invention, the energy storage component is an elastic element. The elastic element is disposed between the limiting retaining ring 102 and the annular base 201, serving as a buffer and a reset function; or, the elastic element is disposed between the check valve block 104 and the base, serving as a buffer and a reset function.

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

[0072] The present invention also provides a compressor including the static disk assembly as described above.

[0073] Example 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 recessed groove 103 above the exhaust port. The exhaust valve body 200 is disposed in the recessed groove 103 and can move up and down within the recessed groove 103.

[0075] The exhaust valve body 200 has a cylindrical structure. An annular base 201 is provided 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 limiting ring 102 is provided on the opening side of the recessed groove 103. The limiting ring 102 is located on the moving path of the annular base 201. The inner diameter of the limiting ring 102 matches the outer diameter of the exhaust valve body 200. An energy storage chamber 203 is provided between the limiting ring 102 and the base.

[0077] Wherein, the distance between the bottom surface of the limiting ring 102 and the bottom of the air outlet 202 is H1, the distance between the top surface of the limiting 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 limiting ring 102 is H3, wherein: H3>H2>H1.

[0078] When the compressor discharges, the high-pressure refrigerant gas flows out from the discharge port 301, causing the discharge valve body 200 to move upward. During this process, the high-pressure gas flow first enters the annular space above the annular base 201 and below the limiting ring 102 through the outlet 202 of the discharge valve body 200. After the discharge valve body 200 moves upward a distance H1, the outlet 202 of the discharge valve body 200 is completely surrounded by the limiting ring 102.

[0079] As the exhaust valve body 200 continues to move upward a distance H2-H1, the annular space above the annular base 201 and below the limiting ring 102 of the exhaust valve body 200 becomes a continuously compressed closed space, further increasing the pressure of the previously filled high-pressure gas. Since the area of ​​the upper cover of the exhaust valve body 200 is much larger than the area of ​​this annular space, the higher pressure gas in the annular space only slows down the upward movement of the exhaust valve body 200, preventing it from impacting the limiting ring 102 and thus reducing the rigid contact between the exhaust valve body 200 and the limiting ring 102.

[0080] When the exhaust valve body 200 moves upward a distance H2, the exhaust port 202 of the exhaust valve body 200 begins to disengage from the limiting ring 102, allowing the high-pressure airflow to exit the exhaust valve body 200. After exhaust is completed, the exhaust valve body 200 quickly resets under the action of high-pressure gas in the annular space above the annular base 201 and below the limiting ring 102, preventing external gas from entering the exhaust port 301.

[0081] Example 2:

[0082] The difference between this embodiment 2 and embodiment 1 is that: the exhaust valve body 200 is fixedly mounted on the stationary disc body 300, and check valve blocks 104 are provided in the exhaust direction of both exhaust ports 202. The check valve blocks 104 are provided with arc-shaped surfaces 109, and the arc-shaped surfaces 109 are adapted to the outer wall of the exhaust valve body 200.

[0083] The check valve block 104 is movably disposed on the stationary disc body 300 so that the check valve block 104 can move close to the exhaust valve body 200 to block the exhaust port 202; or move away from the exhaust valve body 200 to open the exhaust port 202.

[0084] The static plate body 300 is provided with a sliding groove 107, and 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 bottom of the sliding guide post 108 and the sliding groove 107.

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

[0086] When the compressor discharges, the high-pressure refrigerant gas flows out from the discharge port 301. Part of the high-pressure gas discharged from the discharge port 301 enters the energy storage chamber 203 through the vent 106 and the airflow channel 105. The high-pressure gas also discharges through the outlet 202 on the discharge valve body 200, thereby pushing the check valve block 104 away from the outlet 202. When the check valve block 104 moves away from the outlet 202, the connection between the vent 106 and the airflow channel 105 is broken. The high-pressure gas stored in the energy storage chamber 203 is compressed by the check valve block 104, thereby avoiding rigid contact between the check valve block 104 and the discharge valve seat 100 and reducing noise during discharge. After the discharge is completed, the compressed high-pressure gas stored in the storage chamber drives the check valve plate to move towards the outlet 202, thereby closing the outlet 202 and preventing external gas from entering the discharge port 301.
