Description

Technical Field

[0001] The utility model relates to the technical field of compressor equipment, in particular to a partition plate component, a compressor and an air conditioner. Background Art

[0002] At present, the scroll compressor in the related art is internally provided with a temperature protection device, which is arranged on the partition plate. Specifically, the temperature protection device generally includes a bimetallic strip and a cover plate. When encountering an abnormal situation, that is, the exhaust temperature exceeds the maximum temperature requirement, the bimetallic strip will be activated to allow the high-temperature and high-pressure refrigerant to flow into the low-pressure side to reduce the pressure on the high-pressure side and at the same time, increase the temperature on the low-pressure side. Since a protector is provided on the low-pressure side, the high-temperature gas will eventually activate the protector and the compressor will be powered off, thereby protecting the compressor.

[0003] However, after the temperature protection device is installed, there will be a gap at the angle between the cover plate and the partition plate. When the bimetallic strip moves in the cover plate and falls back randomly, it may be stuck at the angle between the cover plate and the partition plate, causing the temperature protection device to fail, increase the power consumption of the compressor, and reduce the energy efficiency of the compressor. Utility Model Content

[0004] The embodiments of the utility model are intended to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of an embodiment of the utility model provides a partition plate assembly.

[0006] A second aspect of an embodiment of the utility model provides a compressor.

[0007] A third aspect of the embodiments of the present utility model provides an air conditioner.

[0008] In view of this, according to the first aspect of an embodiment of the utility model, a partition plate assembly is provided, the partition plate assembly is used for a compressor, the compressor includes an intake chamber and an exhaust chamber, the partition plate assembly includes: a partition plate, the partition plate is provided with a connecting port, the intake chamber and the exhaust chamber are arranged on both sides of the partition plate; a mounting member, which is arranged on the partition plate and is enclosed with the partition plate to form a mounting cavity; a valve plate, which is movably arranged in the mounting cavity and is used to open or close the connecting port; a shielding portion, which is arranged in the mounting cavity and is at least partially located at the connection between the mounting member and the partition plate.

[0009] The partition plate assembly provided by the embodiment of the utility model includes a partition plate, a mounting member, a valve plate and a shielding portion. Specifically, a connecting port is provided on the partition plate, the mounting member is provided on the partition plate, and the mounting member and the partition plate are enclosed to form a mounting cavity, and the valve plate can move in the mounting cavity to open or close the connecting port.

[0010] Specifically, when the compressor operates normally, the valve plate closes the communication port so that the exhaust chamber and the suction chamber are not connected.

[0011] When the compressor has an abnormal situation in which the exhaust temperature exceeds the maximum temperature requirement during operation, that is, the temperature in the exhaust chamber is too high, at this time, the valve plate moves in the installation chamber to open the connecting port, so that the exhaust chamber is connected to the suction chamber through the connecting port, that is, the high-temperature and high-pressure refrigerant in the exhaust chamber will flow into the suction chamber through the connecting port, thereby reducing the pressure in the exhaust chamber. At the same time, due to the high-temperature and high-pressure refrigerant flowing into the suction chamber, the temperature in the suction chamber rises. When the temperature in the suction chamber reaches the set temperature, the temperature protector located in the suction chamber and electrically connected to the motor assembly is disconnected, and the compressor is powered off, thereby protecting the compressor.

[0012] It is understandable that due to the installation method of the mounting piece and other reasons, a certain gap will generally be formed at the connection between the mounting piece and the partition plate. When the valve plate moves in the mounting cavity to open or close the connecting port, the valve plate is prone to get stuck in the gap between the mounting piece and the partition plate.

[0013] At least a portion of the shielding portion is located at the connection between the mounting piece and the partition plate, thereby shielding the gap formed at the connection between the mounting piece and the partition plate. This can effectively prevent the valve plate from getting stuck in the gap formed between the mounting piece and the partition plate during movement in the mounting cavity, thereby causing the compressor temperature protection function to fail, and ensure that the valve plate can effectively open and close the connecting port.

[0014] In addition, it is understandable that when the compressor is operating normally, the valve plate can effectively close the connecting port, thereby preventing the high-temperature and high-pressure refrigerant in the exhaust chamber from flowing into the suction chamber through the connecting port, thereby causing an increase in the power consumption of the compressor, which is beneficial to improving the energy efficiency of the compressor.

[0015] In addition, the partition plate assembly provided by the above technical solution of the utility model also has the following additional technical features:

[0016] In some technical solutions, optionally, the shielding portion includes a protrusion, a first end of the protrusion is connected to the partition plate, and a second end of the protrusion protrudes and extends in the installation cavity and contacts with an inner wall of the installation component.

[0017] In this technical solution, it is defined that the shielding portion includes a protrusion. Specifically, one end of the protrusion is connected to the partition plate, and the other end of the protrusion protrudes and extends in the installation cavity, thereby effectively shielding the gap formed at the connection between the mounting piece and the partition plate, preventing the valve plate from being stuck in the gap formed by the mounting piece and the partition plate during the movement of the valve plate in the installation cavity, thereby causing the temperature protection function of the compressor to fail, and ensuring that the valve plate can effectively open and close the connecting port.

[0018] Moreover, when the compressor is operating normally, the valve plate can effectively close the connecting port, thereby preventing the high-temperature and high-pressure refrigerant in the exhaust chamber from flowing into the suction chamber through the connecting port, thereby increasing the power consumption of the compressor, which is beneficial to improving the energy efficiency of the compressor.

[0019] In addition, the second end of the protrusion contacts the inner wall of the mounting member, thereby preventing the valve plate from getting stuck between the protrusion and the inner wall of the mounting member during movement in the mounting cavity, thereby ensuring that when the temperature in the compressor exhaust cavity is abnormal, the valve plate can effectively open the communication port to protect the compressor. At the same time, when the compressor is operating normally, ensuring that the valve plate can effectively close the communication port is conducive to reducing the power consumption of the compressor and improving the energy efficiency of the compressor.

[0020] Optionally, the protrusion and the partition plate are an integral structure.

[0021] In some technical solutions, optionally, along the radial direction of the valve plate, the distance between the outer edge of the valve plate and the central axis of the valve plate is greater than the distance between the side surface of the protrusion close to the communication port and the central axis of the valve plate.

[0022] In the technical solution, specifically, along the radial direction of the valve plate, the distance between the outer edge of the valve plate and the central axis of the valve plate is a first distance, and the distance between the side of the protrusion close to the communication port and the central axis of the valve plate is a second distance, wherein the first distance is greater than the second distance. In other words, along the axial direction of the valve plate, the outer edge of the valve plate is opposite to the protrusion, thereby ensuring that the protrusion can effectively prevent the valve plate from being stuck in the gap formed by the mounting member and the partition plate, while ensuring that the valve plate can effectively open and close the communication port during the movement of the valve plate in the mounting cavity, thereby improving the reliability of the compressor.

[0023] In some technical solutions, optionally, the protrusion is an annular protrusion.

[0024] In this technical solution, the protrusion is limited to an annular protrusion, so that the gap formed at the connection between the mounting piece and the partition plate can be effectively blocked, further preventing the valve plate from being stuck in the gap formed by the mounting piece and the partition plate during movement in the mounting cavity, thereby causing the compressor temperature protection function to fail, and ensuring that the valve plate can effectively open and close the connecting port.

[0025] In some technical solutions, optionally, there are multiple protrusions, and the multiple protrusions are arranged at intervals.

[0026] In this technical solution, the number of protrusions is limited to multiple. Specifically, the multiple protrusions are arranged at intervals, so that the gap formed at the connection between the mounting piece and the partition plate can be effectively blocked, further preventing the valve plate from being stuck in the gap formed by the mounting piece and the partition plate during the movement of the valve plate in the mounting cavity, thereby causing the temperature protection function of the compressor to fail. This ensures that the valve plate can effectively open and close the connecting port while saving material usage, which is beneficial to reducing the production cost of the compressor.

[0027] In some technical schemes, optionally, the mounting member includes a main body and a mounting portion, wherein the main body and the partition plate enclose a mounting cavity, the mounting portion is arranged on a side of the main body away from the mounting cavity, and is connected to the partition plate, and the connection between the main body and the mounting portion has an arc-shaped surface, and the arc-shaped surface is located in the mounting cavity; the height h of the protrusion and the radius r of the arc-shaped surface satisfy h≥r / 2.

[0028] In this technical solution, it is defined that the mounting member includes a body and a mounting portion. Specifically, the mounting portion is arranged on a side of the body away from the mounting cavity, and the mounting portion is connected to the partition plate, so as to achieve fixed installation of the mounting member. The connection between the body and the mounting portion forms an arc surface, and the arc surface is located in the mounting cavity, that is, the arc surface is located at the connection between the body and the partition plate.

[0029] The height of the protrusion is greater than or equal to half of the radius of the arc surface, that is, the protruding height of the protrusion in the installation cavity is limited, so that the gap formed at the connection between the mounting piece and the partition plate can be effectively blocked, avoiding the valve plate from being stuck in the gap formed by the mounting piece and the partition plate during movement in the installation cavity, thereby causing the compressor temperature protection function to fail, and ensuring that the valve plate can effectively open and close the connecting port.

[0030] Optionally, the main body and the mounting portion are an integrated structure.

[0031] In some technical solutions, optionally, the partition plate is provided with a mounting groove, and at least a portion of the mounting member is disposed in the mounting groove; wherein the mounting portion is located between the shielding portion and the groove wall of the mounting groove.

[0032] In this technical solution, it is defined that the partition plate is provided with a mounting groove. Specifically, at least part of the mounting member is embedded in the mounting groove. On the one hand, it is helpful to reduce the overall thickness of the partition plate assembly and reduce the space occupied by the mounting member in the exhaust cavity. On the other hand, the mounting groove can also play a positioning role, which is helpful to reduce the difficulty of installation and improve the installation efficiency.

[0033] The mounting portion is located between the shielding portion and the groove wall of the mounting groove, that is, the mounting portion is clamped between the shielding portion and the groove wall of the mounting groove, which is beneficial to improve the installation stability of the mounting part and ensure that when the temperature in the exhaust chamber is abnormal, the temperature protection function of the compressor can be effectively turned on to extend the service life of the compressor.

[0034] In some technical solutions, optionally, the mounting piece is further provided with a through-flow hole, which is communicated with the mounting cavity and is used to communicate with the exhaust cavity.

[0035] In this technical solution, it is defined that the mounting piece is further provided with a through-flow hole. Specifically, the through-flow hole is communicated with the mounting cavity, and the through-flow hole is communicated with the exhaust cavity.

[0036] Specifically, when the compressor encounters an abnormal situation in which the exhaust temperature exceeds the maximum temperature requirement during operation, that is, the temperature in the exhaust chamber is too high, at this time, the valve plate moves in the installation chamber to open the connecting port, and the high-temperature and high-pressure refrigerant in the exhaust chamber enters the installation chamber through the flow hole and flows into the suction chamber through the connecting port, thereby reducing the pressure in the exhaust chamber.

[0037] In some technical solutions, optionally, a portion of the valve plate is recessed toward a side away from the through-flow hole to form a convex hull, and when the valve plate closes the communication port, at least a portion of the convex hull is located in the communication port.

[0038] In this technical solution, a part of the valve plate is recessed toward the side away from the flow hole to form a convex bulge. When the compressor operates normally, at least part of the convex bulge is located in the connecting port, so that the connecting port can be effectively closed, thereby preventing the high-temperature and high-pressure refrigerant in the exhaust chamber from flowing into the suction chamber through the connecting port, which in turn leads to an increase in the power consumption of the compressor, and is beneficial to improving the energy efficiency of the compressor.

[0039] In some technical solutions, optionally, the valve plate includes a first metal layer and a second metal layer connected to each other, and the first metal layer is located on a side of the second metal layer away from the connecting port; wherein the thermal expansion coefficient of the first metal layer is greater than the thermal expansion coefficient of the second metal layer.

[0040] In this technical solution, it is defined that the valve sheet includes a first metal layer and a second metal layer. Specifically, the first metal layer and the second metal layer are connected, and the first metal layer is located on the side of the second metal layer away from the connecting port, that is, the first metal layer is the top metal sheet and the second metal layer is the bottom metal sheet.

[0041] The thermal expansion coefficient of the first metal layer is greater than that of the second metal layer. When the exhaust temperature of the compressor exceeds the maximum temperature requirement during operation, that is, the temperature in the exhaust chamber is too high, the first metal layer and the second metal layer are deformed by the heat. Since the thermal expansion coefficient of the first metal layer is greater than that of the second metal layer, the first metal layer and the second metal layer are deformed to different degrees, so that the valve plate pops up in the installation cavity to open the connecting port.

[0042] Since the valve plate opens the connecting port, the exhaust chamber is connected to the suction chamber through the connecting port, that is, the high-temperature and high-pressure refrigerant in the exhaust chamber will flow into the suction chamber through the connecting port, thereby reducing the pressure in the exhaust chamber. At the same time, since the high-temperature and high-pressure refrigerant flows into the suction chamber, the temperature in the suction chamber increases. When the temperature in the suction chamber reaches the set temperature, the temperature protector located in the suction chamber and electrically connected to the motor assembly is disconnected, and the compressor is powered off, thereby protecting the compressor.

[0043] According to the second aspect of the utility model, a compressor is provided, comprising a partition plate assembly as provided by any of the above technical solutions, thereby having all the beneficial technical effects of the partition plate assembly, which will not be repeated here.

[0044] Furthermore, the compressor also includes a shell and a compression assembly, wherein a partition plate is arranged in the shell and divides the shell into an intake chamber and an exhaust chamber, a mounting part is arranged on a side of the partition plate located in the exhaust chamber, the compression assembly is arranged in the intake chamber, and the compression assembly is provided with an exhaust port and a compression chamber that are connected, the compression chamber is connected to the intake chamber, and the exhaust port is connected to the exhaust chamber.

[0045] The compressor provided by the embodiment of the utility model includes a shell, a compression assembly and a partition plate assembly. Specifically, the partition plate is arranged in the shell, and the partition plate divides the shell into an intake chamber and an exhaust chamber. The mounting part is arranged on the side of the partition plate located in the exhaust chamber, that is, the valve plate is located on the side of the partition plate located in the exhaust chamber.

[0046] The compression assembly is arranged in the suction chamber, and the compression assembly is provided with an exhaust port and a compression chamber, and the exhaust port is communicated with the compression chamber. Optionally, the compression assembly includes a fixed scroll and a movable scroll, the fixed scroll and the movable scroll enclose the compression chamber, and the fixed scroll is provided with an exhaust port.

[0047] Specifically, when the compressor is running, the refrigerant enters the compression chamber through the suction chamber, and the movable scroll rotates linearly relative to the fixed scroll to compress the refrigerant entering the compression chamber. When the compressed refrigerant reaches the exhaust pressure, the high-temperature and high-pressure refrigerant enters the exhaust chamber through the exhaust port.

[0048] When the compressor operates normally, the valve plate closes the communication port so that the exhaust chamber and the suction chamber are not connected.

[0049] When the compressor has an abnormal situation in which the exhaust temperature exceeds the maximum temperature requirement during operation, that is, the temperature in the exhaust chamber is too high, at this time, the valve plate moves in the installation chamber to open the connecting port, so that the exhaust chamber is connected to the suction chamber through the connecting port, that is, the high-temperature and high-pressure refrigerant in the exhaust chamber will flow into the suction chamber through the connecting port, thereby reducing the pressure in the exhaust chamber. At the same time, due to the high-temperature and high-pressure refrigerant flowing into the suction chamber, the temperature in the suction chamber rises. When the temperature in the suction chamber reaches the set temperature, the temperature protector located in the suction chamber and electrically connected to the motor assembly is disconnected, and the compressor is powered off, thereby protecting the compressor.

[0050] It is understandable that due to the installation method of the mounting piece and other reasons, a certain gap will generally be formed at the connection between the mounting piece and the partition plate. When the valve plate moves in the mounting cavity to open or close the connecting port, the valve plate is prone to get stuck in the gap between the mounting piece and the partition plate.

[0051] At least a portion of the shielding portion is located at the connection between the mounting piece and the partition plate, thereby shielding the gap formed at the connection between the mounting piece and the partition plate. This can effectively prevent the valve plate from getting stuck in the gap formed between the mounting piece and the partition plate during movement in the mounting cavity, thereby causing the compressor temperature protection function to fail, and ensure that the valve plate can effectively open and close the connecting port.

[0052] In addition, it is understandable that when the compressor is operating normally, the valve plate can effectively close the connecting port, thereby preventing the high-temperature and high-pressure refrigerant in the exhaust chamber from flowing into the suction chamber through the connecting port, thereby causing an increase in the power consumption of the compressor, which is beneficial to improving the energy efficiency of the compressor.

[0053] In addition, the compressor provided by the above technical solution of the utility model also has the following additional technical features:

[0054] In some technical solutions, optionally, the compressor also includes a motor assembly and a temperature protector, wherein the motor assembly is connected to the compression assembly, and the temperature protector is arranged in the suction chamber and electrically connected to the motor assembly.

[0055] In the technical solution, it is defined that the compressor also includes a motor assembly and a temperature protector, and specifically, the motor assembly is connected to the compression assembly. The motor assembly is connected to the movable scroll. Specifically, under the drive of the motor assembly, the movable scroll rotates relative to the fixed scroll to compress the refrigerant in the compression chamber.

[0056] The temperature protector is arranged in the suction chamber, and the temperature protector is electrically connected to the motor assembly. Specifically, when the exhaust temperature of the compressor exceeds the maximum temperature requirement during operation, that is, the temperature in the exhaust chamber is too high, at this time, the valve plate moves in the installation chamber to open the connecting port, so that the exhaust chamber is connected with the suction chamber through the connecting port, that is, the high-temperature and high-pressure refrigerant in the exhaust chamber will flow into the suction chamber through the connecting port, thereby reducing the pressure in the exhaust chamber.

[0057] At the same time, as the high-temperature and high-pressure refrigerant flows into the suction chamber, the temperature in the suction chamber rises. When the temperature in the suction chamber reaches the set temperature, the temperature protector is disconnected, the connection path between the motor assembly and the power supply is disconnected, and the compressor is powered off, thereby protecting the compressor.

[0058] According to the third aspect of the utility model, an air conditioner is provided, comprising a partition plate assembly or a compressor as provided by any of the above technical solutions, thereby having all the beneficial technical effects of the partition plate assembly or the compressor, which will not be repeated here.

DETAILED DESCRIPTION

[0067] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0068] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0069] Refer to the following Figures 1 to 4 The partition plate assembly 100, the compressor 200 and the air conditioner provided according to some embodiments of the present invention are described.

[0070] In one embodiment according to the present application, Figure 1 , Figure 2 and Figure 4 As shown, a partition plate assembly 100 is proposed. The partition plate assembly 100 is used for a compressor 200. The compressor 200 includes an intake chamber 230 and an exhaust chamber 240. The partition plate assembly 100 includes: a partition plate 110, the partition plate 110 is provided with a connecting port 111, and the intake chamber 230 and the exhaust chamber 240 are arranged on both sides of the partition plate 110; a mounting member 120, which is arranged on the partition plate 110 and enclosed with the partition plate 110 to form a mounting chamber 130; a valve plate 140, which is movably arranged in the mounting chamber 130 and is used to open or close the connecting port 111; a shielding portion 150, which is arranged in the mounting chamber 130 and is at least partially located at the connection between the mounting member 120 and the partition plate 110.

[0071] The partition plate assembly 100 provided in the embodiment of the utility model includes a partition plate 110, a mounting member 120, a valve plate 140 and a shielding portion 150. Specifically, a connecting port 111 is provided on the partition plate 110, the mounting member 120 is provided on the partition plate 110, and the mounting member 120 and the partition plate 110 are enclosed to form a mounting cavity 130, and the valve plate 140 can move in the mounting cavity 130 to open or close the connecting port 111.

[0072] Specifically, when the compressor 200 operates normally, the valve plate 140 closes the communication port 111 so that the exhaust chamber 240 and the suction chamber 230 are not connected.

[0073] When the compressor 200 has an abnormal situation that the exhaust temperature exceeds the maximum temperature requirement during operation, that is, the temperature in the exhaust chamber 240 is too high, at this time, the valve plate 140 moves in the installation chamber 130 to open the connecting port 111, so that the exhaust chamber 240 is connected with the suction chamber 230 through the connecting port 111, that is, the high-temperature and high-pressure refrigerant in the exhaust chamber 240 will flow into the suction chamber 230 through the connecting port 111, thereby reducing the pressure in the exhaust chamber 240. At the same time, due to the high-temperature and high-pressure refrigerant flowing into the suction chamber 230, the temperature in the suction chamber 230 increases. When the temperature in the suction chamber 230 reaches the set temperature, the temperature protector 260 located in the suction chamber 230 and electrically connected to the motor assembly 250 is disconnected, and the compressor 200 is powered off, thereby protecting the compressor 200.

[0074] It is understandable that due to the installation method of the mounting member 120 and other reasons, a certain gap is generally formed at the connection between the mounting member 120 and the partition plate 110. When the valve plate 140 moves in the mounting cavity 130 to open or close the connecting port 111, it is easy for the valve plate 140 to get stuck in the gap between the mounting member 120 and the partition plate 110.

[0075] At least a portion of the shielding portion 150 is located at the connection between the mounting member 120 and the partition plate 110, thereby shielding the gap formed at the connection between the mounting member 120 and the partition plate 110. This can effectively prevent the valve plate 140 from being stuck in the gap formed between the mounting member 120 and the partition plate 110 during movement in the mounting cavity 130, thereby causing the temperature protection function of the compressor 200 to fail, and ensure that the valve plate 140 can effectively open and close the connecting port 111.

[0076] In addition, it can be understood that when the compressor 200 operates normally, since the valve plate 140 can effectively close the connecting port 111, it can prevent the high-temperature and high-pressure refrigerant in the exhaust chamber 240 from flowing into the suction chamber 230 through the connecting port 111, thereby preventing the power consumption of the compressor 200 from increasing, which is beneficial to improving the energy efficiency of the compressor 200.

[0077] like Figure 1 As shown, in some embodiments, optionally, the shielding portion 150 includes a protrusion 151 , a first end of the protrusion 151 is connected to the partition plate 110 , and a second end of the protrusion 151 protrudes and extends in the installation cavity 130 and contacts the inner wall of the installation member 120 .

[0078] In this embodiment, the shielding portion 150 is defined to include a protrusion 151. Specifically, one end of the protrusion 151 is connected to the partition plate 110, and the other end of the protrusion 151 protrudes and extends in the installation cavity 130, thereby effectively shielding the gap formed at the connection between the installation member 120 and the partition plate 110, preventing the valve plate 140 from being stuck in the gap formed by the installation member 120 and the partition plate 110 during the movement in the installation cavity 130, thereby causing the temperature protection function of the compressor 200 to fail, and ensuring that the valve plate 140 can effectively open and close the connecting port 111.

[0079] Moreover, when the compressor 200 operates normally, since the valve plate 140 can effectively close the connecting port 111, it can prevent the high-temperature and high-pressure refrigerant in the exhaust chamber 240 from flowing into the suction chamber 230 through the connecting port 111, thereby preventing the power consumption of the compressor 200 from increasing, which is beneficial to improving the energy efficiency of the compressor 200.

[0080] In addition, the second end of the protrusion 151 contacts the inner wall of the mounting member 120, so that the valve plate 140 can be prevented from being stuck between the protrusion 151 and the inner wall of the mounting member 120 during the movement in the mounting cavity 130, thereby ensuring that when an abnormal temperature occurs in the exhaust cavity 240 of the compressor 200, the valve plate 140 can effectively open the communication port 111 to protect the compressor 200. At the same time, when the compressor 200 is operating normally, it is ensured that the valve plate 140 can effectively close the communication port 111, which is conducive to reducing the power consumption of the compressor 200 and improving the energy efficiency of the compressor 200.

[0081] Optionally, the protrusion 151 and the partition plate 110 are an integral structure.

[0082] like Figure 1 As shown, in some embodiments, optionally, along the radial direction of the valve plate 140 , the distance between the outer edge of the valve plate 140 and the central axis of the valve plate 140 is greater than the distance between the side of the protrusion 151 close to the connecting port 111 and the central axis of the valve plate 140 .

[0083] In this embodiment, specifically, along the radial direction of the valve disc 140, the distance between the outer edge of the valve disc 140 and the central axis of the valve disc 140 is a first distance, and the distance between the side of the protrusion 151 close to the communication port 111 and the central axis of the valve disc 140 is a second distance, wherein the first distance is greater than the second distance. In other words, along the axial direction of the valve disc 140, the outer edge of the valve disc 140 is opposite to the protrusion 151, thereby ensuring that the protrusion 151 can effectively prevent the valve disc 140 from being stuck in the gap formed by the mounting member 120 and the partition plate 110, and ensuring that the valve disc 140 can effectively open and close the communication port 111 during the movement in the mounting cavity 130, thereby improving the reliability of the compressor 200.

[0084] In some embodiments, optionally, the protrusion 151 is an annular protrusion.

[0085] In this embodiment, the protrusion 151 is defined as an annular protrusion, so that the gap formed at the connection between the mounting member 120 and the partition plate 110 can be effectively blocked, and the valve plate 140 can be further prevented from being stuck in the gap formed by the mounting member 120 and the partition plate 110 during the movement in the mounting cavity 130, thereby causing the temperature protection function of the compressor 200 to fail, thereby ensuring that the valve plate 140 can effectively open and close the connecting port 111.

[0086] In some embodiments, optionally, there are multiple protrusions 151 , and the multiple protrusions 151 are arranged at intervals.

[0087] In this embodiment, the number of protrusions 151 is limited to multiple. Specifically, the multiple protrusions 151 are arranged at intervals, so that the gap formed at the connection between the mounting member 120 and the partition plate 110 can be effectively blocked, and the valve plate 140 is further prevented from being stuck in the gap formed by the mounting member 120 and the partition plate 110 during the movement in the mounting cavity 130, thereby causing the temperature protection function of the compressor 200 to fail. This ensures that the valve plate 140 can effectively open and close the connecting port 111, while saving material usage, which is beneficial to reducing the production cost of the compressor 200.

[0088] like Figure 1 As shown, in some embodiments, optionally, the mounting member 120 includes a main body 121 and a mounting portion 122, wherein the main body 121 and the partition plate 110 enclose a mounting cavity 130, the mounting portion 122 is arranged on a side of the main body 121 away from the mounting cavity 130, and is connected to the partition plate 110, and a connection between the main body 121 and the mounting portion 122 has an arcuate surface 123, and the arcuate surface 123 is located in the mounting cavity 130; the height h of the protrusion 151 and the radius r of the arcuate surface 123 satisfy h≥r / 2.

[0089] In this embodiment, the mounting member 120 is defined to include a body 121 and a mounting portion 122. Specifically, the mounting portion 122 is disposed on a side of the body 121 away from the mounting cavity 130, and the mounting portion 122 is connected to the partition plate 110, thereby achieving fixed installation of the mounting member 120. An arcuate surface 123 is formed at the connection between the body 121 and the mounting portion 122, and the arcuate surface 123 is located in the mounting cavity 130, that is, the arcuate surface 123 is located at the connection between the body 121 and the partition plate 110.

[0090] The height of the protrusion 151 is greater than or equal to half the radius of the arc surface 123, that is, the protruding height of the protrusion 151 in the installation cavity 130 is limited, so that the gap formed at the connection between the installation component 120 and the partition plate 110 can be effectively blocked, and the valve plate 140 is prevented from being stuck in the gap formed by the installation component 120 and the partition plate 110 during the movement in the installation cavity 130, thereby causing the temperature protection function of the compressor 200 to fail, and ensuring that the valve plate 140 can effectively open and close the connecting port 111.

[0091] Optionally, the main body 121 and the mounting portion 122 are an integral structure.

[0092] like Figure 1 As shown, in some embodiments, optionally, the partition plate 110 is provided with a mounting groove 112 , and at least a portion of the mounting member 120 is disposed in the mounting groove 112 ; wherein the mounting portion 122 is located between the shielding portion 150 and the groove wall of the mounting groove 112 .

[0093] In this embodiment, the partition plate 110 is defined to be provided with a mounting groove 112. Specifically, at least a portion of the mounting member 120 is embedded in the mounting groove 112. On the one hand, it is helpful to reduce the overall thickness of the partition plate assembly 100 and reduce the space occupied by the mounting member 120 in the exhaust cavity 240. On the other hand, the mounting groove 112 can also play a positioning role, which is helpful to reduce the difficulty of installation and improve the installation efficiency.

[0094] The mounting portion 122 is located between the shielding portion 150 and the groove wall of the mounting groove 112, that is, the mounting portion 122 is clamped between the shielding portion 150 and the groove wall of the mounting groove 112, which is beneficial to improve the installation stability of the mounting member 120 and ensure that when the temperature in the exhaust chamber 240 is abnormal, the temperature protection function of the compressor 200 can be effectively turned on to extend the service life of the compressor 200.

[0095] like Figure 1 As shown, in some embodiments, optionally, the mounting member 120 is further provided with a through-hole 124 , and the through-hole 124 is communicated with the mounting cavity 130 and is used to communicate with the exhaust cavity 240 .

[0096] In this embodiment, it is defined that the mounting member 120 is further provided with a through-hole 124 . Specifically, the through-hole 124 is communicated with the mounting cavity 130 , and the through-hole 124 is communicated with the exhaust cavity 240 .

[0097] Specifically, when the compressor 200 encounters an abnormal situation in which the exhaust temperature exceeds the maximum temperature requirement during operation, that is, the temperature in the exhaust chamber 240 is too high, at this time, the valve plate 140 moves in the installation chamber 130 to open the connecting port 111, and the high-temperature and high-pressure refrigerant in the exhaust chamber 240 enters the installation chamber 130 through the flow hole 124, and flows into the suction chamber 230 through the connecting port 111, thereby reducing the pressure in the exhaust chamber 240.

[0098] like Figure 1 and Figure 3 As shown, in some embodiments, optionally, a portion of the valve plate 140 is recessed toward a side away from the through hole 124 to form a convex hump 160 , and when the valve plate 140 closes the communication port 111 , at least a portion of the convex hump 160 is located in the communication port 111 .

[0099] In this embodiment, a portion of the valve plate 140 is recessed toward a side away from the flow hole 124 to form a bulge 160. When the compressor 200 operates normally, at least a portion of the bulge 160 is located in the connecting port 111, so that the connecting port 111 can be effectively closed, thereby preventing the high-temperature and high-pressure refrigerant in the exhaust chamber 240 from flowing into the suction chamber 230 through the connecting port 111, thereby preventing the power consumption of the compressor 200 from increasing, which is beneficial to improving the energy efficiency of the compressor 200.

[0100] like Figure 1 and Figure 3 As shown, in some embodiments, optionally, the valve sheet 140 includes a first metal layer 141 and a second metal layer 142 connected to each other, and the first metal layer 141 is located on the side of the second metal layer 142 away from the connecting port 111; wherein the thermal expansion coefficient of the first metal layer 141 is greater than the thermal expansion coefficient of the second metal layer 142.

[0101] In this embodiment, the valve sheet 140 is defined to include a first metal layer 141 and a second metal layer 142. Specifically, the first metal layer 141 and the second metal layer 142 are connected, and the first metal layer 141 is located on the side of the second metal layer 142 away from the connecting port 111. That is, the first metal layer 141 is a top metal sheet, and the second metal layer 142 is a bottom metal sheet.

[0102] The thermal expansion coefficient of the first metal layer 141 is greater than that of the second metal layer 142. When the compressor 200 encounters an abnormal situation in which the exhaust temperature exceeds the maximum temperature requirement during operation, that is, the temperature in the exhaust chamber 240 is too high, the first metal layer 141 and the second metal layer 142 are deformed by the heat. Since the thermal expansion coefficient of the first metal layer 141 is greater than that of the second metal layer 142, the first metal layer 141 and the second metal layer 142 are deformed to different degrees, so that the valve plate 140 pops up in the installation cavity 130 to open the connecting port 111.

[0103] Since the valve plate 140 opens the communication port 111, the exhaust chamber 240 is connected with the suction chamber 230 through the communication port 111, that is, the high-temperature and high-pressure refrigerant in the exhaust chamber 240 flows into the suction chamber 230 through the communication port 111, thereby reducing the pressure in the exhaust chamber 240. At the same time, since the high-temperature and high-pressure refrigerant flows into the suction chamber 230, the temperature in the suction chamber 230 increases. When the temperature in the suction chamber 230 reaches the set temperature, the temperature protector 260 located in the suction chamber 230 and electrically connected to the motor assembly 250 is disconnected, and the compressor 200 is powered off, thereby protecting the compressor 200.

[0104] According to the second aspect of the present invention, a compressor 200 is provided, comprising a partition plate assembly 100 as provided in any of the above embodiments, and thus having all the beneficial technical effects of the partition plate assembly 100, which will not be described in detail herein.

[0105] like Figure 4 As shown, further, the compressor 200 also includes a shell 210 and a compression assembly 220, wherein the partition plate 110 is arranged in the shell 210, and divides the shell 210 into an intake chamber 230 and an exhaust chamber 240, the mounting member 120 is arranged on one side of the partition plate 110 located in the exhaust chamber 240, the compression assembly 220 is arranged in the intake chamber 230, and the compression assembly 220 is provided with an exhaust port 221 and a compression chamber 222 that are connected, the compression chamber 222 is connected to the intake chamber 230, and the exhaust port 221 is connected to the exhaust chamber 240.

[0106] The compressor 200 provided in the embodiment of the utility model includes a shell 210, a compression assembly 220 and a partition plate assembly 100. Specifically, the partition plate 110 is arranged in the shell 210, and the partition plate 110 divides the shell 210 into an intake chamber 230 and an exhaust chamber 240. The mounting member 120 is arranged on the side of the partition plate 110 located in the exhaust chamber 240, that is, the valve plate 140 is located on the side of the partition plate 110 located in the exhaust chamber 240.

[0107] The compression assembly 220 is disposed in the suction chamber 230, and the compression assembly 220 is provided with an exhaust port 221 and a compression chamber 222, and the exhaust port 221 is communicated with the compression chamber 222. Optionally, the compression assembly 220 includes a fixed scroll 223 and a movable scroll 224, the fixed scroll 223 and the movable scroll 224 enclose the compression chamber 222, and the fixed scroll 223 is provided with an exhaust port 221.

[0108] Specifically, when the compressor 200 is running, the refrigerant enters the compression chamber 222 through the suction chamber 230, and the movable scroll 224 rotates linearly relative to the fixed scroll 223 to compress the refrigerant entering the compression chamber 222. When the compressed refrigerant reaches the exhaust pressure, the high-temperature and high-pressure refrigerant enters the exhaust chamber 240 through the exhaust port 221.

[0109] When the compressor 200 operates normally, the valve plate 140 closes the communication port 111 so that the exhaust chamber 240 and the suction chamber 230 are not connected.

[0110] When the compressor 200 has an abnormal situation that the exhaust temperature exceeds the maximum temperature requirement during operation, that is, the temperature in the exhaust chamber 240 is too high, at this time, the valve plate 140 moves in the installation chamber 130 to open the connecting port 111, so that the exhaust chamber 240 is connected with the suction chamber 230 through the connecting port 111, that is, the high-temperature and high-pressure refrigerant in the exhaust chamber 240 will flow into the suction chamber 230 through the connecting port 111, thereby reducing the pressure in the exhaust chamber 240. At the same time, due to the high-temperature and high-pressure refrigerant flowing into the suction chamber 230, the temperature in the suction chamber 230 increases. When the temperature in the suction chamber 230 reaches the set temperature, the temperature protector 260 located in the suction chamber 230 and electrically connected to the motor assembly 250 is disconnected, and the compressor 200 is powered off, thereby protecting the compressor 200.

[0111] It is understandable that due to the installation method of the mounting member 120 and other reasons, a certain gap is generally formed at the connection between the mounting member 120 and the partition plate 110. When the valve plate 140 moves in the mounting cavity 130 to open or close the connecting port 111, it is easy for the valve plate 140 to get stuck in the gap between the mounting member 120 and the partition plate 110.

[0112] At least a portion of the shielding portion 150 is located at the connection between the mounting member 120 and the partition plate 110, thereby shielding the gap formed at the connection between the mounting member 120 and the partition plate 110. This can effectively prevent the valve plate 140 from being stuck in the gap formed between the mounting member 120 and the partition plate 110 during movement in the mounting cavity 130, thereby causing the temperature protection function of the compressor 200 to fail, and ensure that the valve plate 140 can effectively open and close the connecting port 111.

[0113] In addition, it can be understood that when the compressor 200 operates normally, since the valve plate 140 can effectively close the connecting port 111, it can prevent the high-temperature and high-pressure refrigerant in the exhaust chamber 240 from flowing into the suction chamber 230 through the connecting port 111, thereby preventing the power consumption of the compressor 200 from increasing, which is beneficial to improving the energy efficiency of the compressor 200.

[0114] like Figure 4 As shown, in some embodiments, optionally, the compressor 200 also includes a motor assembly 250 and a temperature protector 260, wherein the motor assembly 250 is connected to the compression assembly 220, and the temperature protector 260 is disposed in the suction chamber 230 and electrically connected to the motor assembly 250.

[0115] In this embodiment, it is defined that the compressor 200 further includes a motor assembly 250 and a temperature protector 260. Specifically, the motor assembly 250 is connected to the compression assembly 220. The motor assembly 250 is connected to the movable scroll 224. Specifically, under the drive of the motor assembly 250, the movable scroll 224 performs translational rotation relative to the fixed scroll 223 to compress the refrigerant in the compression chamber 222.

[0116] The temperature protector 260 is arranged in the suction chamber 230, and the temperature protector 260 is electrically connected to the motor assembly 250. Specifically, when the compressor 200 encounters an abnormal situation in which the exhaust temperature exceeds the maximum temperature requirement during operation, that is, the temperature in the exhaust chamber 240 is too high, at this time, the valve plate 140 moves in the installation chamber 130 to open the connecting port 111, so that the exhaust chamber 240 is connected with the suction chamber 230 through the connecting port 111, that is, the high-temperature and high-pressure refrigerant in the exhaust chamber 240 will flow into the suction chamber 230 through the connecting port 111, thereby reducing the pressure in the exhaust chamber 240.

[0117] At the same time, the temperature in the suction chamber 230 increases due to the high-temperature and high-pressure refrigerant flowing into the suction chamber 230. When the temperature in the suction chamber 230 reaches the set temperature, the temperature protector 260 is disconnected, the connection path between the motor assembly 250 and the power supply is disconnected, and the compressor 200 is powered off, thereby protecting the compressor 200.

[0118] According to the third aspect of the utility model, an air conditioner is provided, comprising a partition plate assembly 100 or a compressor 200 as provided in any of the above embodiments, and thus having all the beneficial technical effects of the partition plate assembly 100 or the compressor 200, which will not be repeated here.
