Description

Technical Field

[0001] The present invention relates to the technical field of liquid accumulators, and in particular to a liquid accumulator and a compressor having the same. Background Art

[0002] At present, the compressor accumulator is an important part of the operation of the compressor and air conditioning system. The main function of the compressor accumulator is to store liquid and stabilize pressure, thereby preventing the liquid refrigerant in the refrigeration system from entering the compressor to cause liquid hammer, and maintaining the stability of the suction pressure and reducing suction pulsation. In the prior art, the accumulator is usually installed on the suction side of the compressor and assembled on the side of the compressor main shell through a bracket.

[0003] However, the liquid reservoir in the prior art is generally a cylindrical structure, and the internal structure includes a straight pipe, a filter assembly, a steel pipe, a partition, a bend pipe, and a cylinder, and is basically a symmetrical structure. After being assembled with the main housing of the compressor, there is a problem that the overall center of gravity is far away from the main housing of the compressor, which causes the overall center of gravity of the compressor to be not at the center of the circle of the bottom support foot of the compressor assembly, and then it is easy to cause the compressor to tilt or increase vibration when the compressor is running, resulting in noise problems in the air conditioning or refrigeration system. In addition, the vibration generated when the compressor is running will also be transmitted to the liquid reservoir steel pipe through the bend pipe connection, thereby causing vibration of the liquid reservoir and affecting the normal operation of the liquid reservoir itself. Summary of the invention

[0016] Along the direction from the first barrel section to the second barrel section, the height of the first barrel section is smaller than the height of the second barrel section.

[0017] Further, the liquid reservoir also includes a filter assembly;

[0018] Wherein, the filter assembly is arranged in the first cylinder; or, the filter assembly is arranged at the connection between the first cavity and the second cavity; and / or,

[0019] The filter of the filter assembly is extended along the height direction of the liquid storage cylinder.

Therefore, through the technical solution of the present invention, the technical problem that the compressor in the prior art is prone to vibration during operation can be solved.

[0052] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0053] like Figure 1 As shown, the first embodiment of the present invention provides a liquid reservoir, which is arranged on one side of the structure to be installed and connected to the structure to be installed, and the liquid reservoir includes a liquid reservoir cylinder 10, and the liquid reservoir cylinder 10 includes a first cylinder 11 and a second cylinder 12, the first cylinder 11 surrounds a first cavity 1101, and the second cylinder 12 surrounds a second cavity 1201 connected to the first cavity 1101; the first cylinder 11 has an inlet 111 for introducing a refrigerant, and the second cylinder 12 has an outlet 121 for discharging a refrigerant. Among them, the maximum diameter of the first cylinder 11 is smaller than the minimum diameter of the second cylinder 12; the central axis of the first cylinder 11 is located on the side of the central axis of the second cylinder 12 close to the structure to be installed.

[0054] The liquid reservoir provided by the first embodiment of the present invention is adopted. Since the central axis of the first cylinder 11 is located on the side of the central axis of the second cylinder 12 close to the structure to be installed, and the maximum diameter of the first cylinder 11 is smaller than the minimum diameter of the second cylinder 12, this offset cylinder design helps to shift the center of gravity of the liquid reservoir to the side of the structure to be installed. At the same time, compared with the conventional liquid reservoir structure, such a setting also effectively reduces the dead weight of the liquid reservoir cylinder 10 through the small diameter setting of the first cylinder 11, thereby further making the center of gravity of the liquid reservoir and the structure to be installed as a whole closer to the center of gravity of the structure to be installed. The optimized adjustment of the center of gravity makes the center of gravity of the liquid reservoir closer to the structure to be installed when the liquid reservoir is running, so that the center of gravity of the structure to be installed is as close as possible to its own appearance geometric center of gravity position, thereby reducing the influence of the connection between the liquid reservoir and the structure to be installed on the structure to be installed, effectively reducing the possibility of tilting and vibration of the structure to be installed, thereby reducing the possibility of vibration and tilting of the liquid reservoir, and enhancing the stability and reliability of the system. Therefore, the liquid reservoir provided by this embodiment can solve the technical problem that the compressor in the prior art is prone to vibration during operation.

[0055] Specifically, the structure to be installed is the compressor body 40 .

[0056] It should be noted that the liquid reservoir is also called a liquid distributor.

[0057] Specifically, Figure 1 As shown, in the first embodiment, D2>D1, D2 is the minimum diameter of the second cylinder 12, and D1 is the maximum diameter of the first cylinder 11. Figure 3 As shown, in the third embodiment, D5>D4, D5 is the minimum diameter of the second cylinder 12, and D4 is the maximum diameter of the first cylinder 11.

[0058] Specifically, along the extension direction of the first cylinder 11, at least part of the first cylinder 11 is arranged to protrude from the second cylinder 12. With such a structural arrangement, since the central axis of the first cylinder 11 is located on the side of the central axis of the second cylinder 12 close to the structure to be installed, the overall center of gravity of the accumulator is closer to the compressor to be installed or the basic structure of the refrigeration system, thereby significantly reducing the tilting phenomenon of the compressor during operation, effectively controlling the additional vibration caused by the deviation of the center of gravity, reducing the noise level of the system during operation, and improving the overall mechanical stability and durability.

[0059] Specifically, along the extension direction of the first cylinder 11, the height of the first cylinder 11 is greater than or equal to the height of the second cylinder 12. With such a structural arrangement, since the maximum diameter of the first cylinder 11 is smaller than the minimum diameter of the second cylinder 12, by making the height of the first cylinder 11 greater than or equal to the height of the second cylinder 12, the deadweight of the liquid reservoir cylinder 10 can be reduced as much as possible while ensuring that the volume of the liquid reservoir cylinder 10 is sufficient, thereby further making the center of gravity of the entirety of the liquid reservoir and the structure to be installed closer to the center of gravity of the structure to be installed.

[0060] Specifically, Figure 1 and Figure 2 As shown, in the first or second embodiment, L1≥L2, L1 is the height of the first cylinder 11, and L2 is the height of the second cylinder 12. Figure 3 As shown, in the third embodiment, L3+L4≥L5, L3+L4 is the height of the first cylinder 11, and L5 is the height of the second cylinder 12.

[0061] like Figure 1 and Figure 2 As shown, in Example 1 and Example 2, the first cylinder 11 is located above the second cylinder 12. Such a structural setting is conducive to the natural flow of the refrigerant inside the liquid reservoir. By utilizing gravity, the liquid refrigerant can be more easily deposited in the second cylinder 12, and the separation of gas and liquid is more effective, reducing the liquid hammer phenomenon, protecting the compressor, and improving the circulation efficiency of the refrigerant. At the same time, this layout makes the structural layout more reasonable, and the first cylinder 11 will not occupy too much lateral space, which is conducive to the compact design of the liquid reservoir, saving installation space, and is also easy to maintain and clean.

[0062] like Figure 3 As shown, in the third embodiment, the first cylinder 11 is located on the side of the second cylinder 12 close to the structure to be installed. Such a structural setting not only optimizes the center of gravity distribution of the liquid reservoir, making it closer to the structure to be installed, reducing the vibration and noise caused by the deviation of the center of gravity, but also makes the liquid reservoir more balanced and stable during the overall assembly, which helps to improve the overall performance and reliability of the refrigeration system.

[0063] In the third embodiment, the first barrel 11 includes a first barrel section 112 and a second barrel section 113 which are interconnected, and the first barrel section 112 is located above the second barrel section 113; the inlet 111 is arranged on the first barrel section 112; and the second barrel section 113 is arranged in communication with the second cavity 1201. Among them, the maximum diameter of the first barrel section 112 is smaller than the minimum diameter of the second barrel section 113. With such a structural setting, the deadweight of the first barrel 11 can be further reduced through the segmented design of the first barrel section 112 and the second barrel section 113, thereby reducing the deadweight of the liquid reservoir, thereby further making the center of gravity of the liquid reservoir and the structure to be installed as a whole closer to the center of gravity of the structure to be installed. At the same time, when the refrigerant enters the second barrel section 113, the flow rate slows down due to the increase in diameter, which is conducive to the further separation and stabilization of the refrigerant, improves the liquid-gas separation efficiency, protects the compressor from the direct impact of the liquid refrigerant, and enhances the safety and reliability of the system. In addition, this design allows the refrigerant to undergo a diameter change when transitioning from the first cylinder 11 to the second cylinder 12, thereby further reducing the speed and separating the liquid in the refrigerant. The larger cavity of the second cylinder 12 provides sufficient space for liquid deposition, preventing the liquid in the refrigerant from directly entering the compressor, reducing potential damage to the compressor, and also helping to improve the circulation efficiency of the refrigerant.

[0064] like Figure 3 As shown, in the third embodiment, D3<D4, D3 is the maximum diameter of the first barrel section 112, and D4 is the minimum diameter of the second barrel section 113.

[0065] Specifically, the maximum diameter of the second barrel section 113 is smaller than the minimum diameter of the second barrel 12. Such a structural setting first helps to reduce the deadweight of the first barrel 11, thereby reducing the deadweight of the liquid reservoir, and then making the center of gravity of the liquid reservoir and the structure to be installed closer to the center of gravity of the structure to be installed. At the same time, such a setting makes it necessary for the refrigerant to pass through a channel with a gradually increasing diameter when transitioning from the first barrel 11 to the second barrel 12. This design is conducive to the smooth transition of the refrigerant flow rate, reducing the impact of high-speed flow on the internal structure of the second barrel 12. At the same time, the sudden increase in diameter helps the liquid refrigerant to be thrown to the barrel wall due to the centrifugal force, so that it descends under the action of gravity and is deposited at the bottom of the second barrel 12, achieving more effective liquid-gas separation, reducing the risk of liquid refrigerant entering the compressor, protecting the compressor, and improving the stability and efficiency of the system operation.

[0066] like Figure 3 As shown, in the third embodiment, D4<D5, D4 is the maximum diameter of the second barrel section 113, and D5 is the minimum diameter of the second barrel body 12.

[0067] Specifically, along the direction from the first barrel section 112 to the second barrel section 113, the height of the second barrel section 113 is less than the height of the first barrel section 112. With such a structural arrangement, the deadweight of the liquid reservoir barrel 10 can be minimized, thereby further making the center of gravity of the liquid reservoir and the structure to be installed as a whole closer to the center of gravity of the structure to be installed. And this makes the flow path of the refrigerant designed to descend in the vertical direction when it flows from the first barrel section 112 into the second barrel section 113. This layout utilizes the effect of gravity, which helps the liquid refrigerant to naturally sink to the lower part of the liquid reservoir and separate from the gaseous refrigerant. At the same time, it reduces the turbulence and noise of the airflow when turning, improves the smoothness of the flow inside the liquid reservoir, further optimizes the liquid-gas separation effect of the refrigerant, and reduces the noise during system operation.

[0068] like Figure 3 As shown, in the third embodiment, L4<L3, L4 is the height of the second barrel section 113, and L3 is the height of the first barrel section 112.

[0069] Specifically, along the direction from the first barrel section 112 to the second barrel section 113, the height of the first barrel section 112 is less than the height of the second barrel 12. With such a structural arrangement, the liquid reservoir can be installed on the device more compactly while ensuring sufficient capacity, thereby reducing the occupation of the internal space of the device.

[0070] like Figure 3 As shown, in the third embodiment, L3<L5, L3 is the height of the first barrel section 112, and L5 is the height of the second barrel 12.

[0071] Specifically, the liquid storage device further includes a filter assembly 20. With such a structural arrangement, the filter assembly 20 can effectively filter impurities in the refrigerant to prevent them from entering key components such as the compressor, thereby avoiding damage or blockage to them, and improving the overall reliability and life of the system.

[0072] In the first or second embodiment, the filter assembly 20 is arranged in the first cylinder 11. With such a structural arrangement, since the first cylinder 11 is located on the air intake path of the refrigerant, this position arrangement can filter the incoming refrigerant at the first time, avoid the accumulation of impurities inside the liquid storage device, and reduce the pollution to the subsequent cavity, thereby ensuring the purity of the refrigerant and improving the efficiency of the entire refrigeration cycle.

[0073] In the third embodiment, the filter assembly 20 is disposed at the connection between the first cavity 1101 and the second cavity 1201. With such a structural arrangement, the refrigerant flowing from the first cavity 1101 to the second cavity 1201 can be filtered, ensuring that the refrigerant entering the second cavity 1201 is free of impurities.

[0074] Specifically, the filter of the filter assembly 20 is extended along the height direction of the liquid reservoir cylinder 10. With such a structural arrangement, the vertical arrangement of the filter reduces the risk of blockage caused by the impact of the refrigerant flow, and improves the long-term effectiveness of the filter and the convenience of maintenance of the liquid reservoir. At the same time, this design expands the effective filtration area of ​​the filter and improves the filtration efficiency. At the same time, the vertical arrangement prevents impurities from being evenly distributed on the entire filter surface when the refrigerant flows, but rather deposits more on the side where the filter straddles the bottom of the liquid reservoir cylinder 10, reducing early blockage of the filter caused by uneven distribution of impurities and extending the service life and cleaning cycle of the filter assembly 20.

[0075] Specifically, the liquid reservoir further includes a suction pipe 30, one end of which is inserted into the outlet 121. The other end of the suction pipe 30 is located in the second cavity 1201; or, the other end of the suction pipe 30 is located in the first cavity 1101. With such a structural arrangement, the design that one end of the suction pipe 30 is inserted into the outlet 121 ensures that when the refrigerant is transported from the inside of the liquid reservoir to the compressor body 40, it can be guided by the suction pipe 30, reducing the vortex and gas-liquid mixing phenomenon that may be generated when the refrigerant is directly drawn out from the outlet 121, thereby improving the stability and purity of the refrigerant transportation. The suction pipe 30 can more accurately control the flow path of the refrigerant, reduce the suction pulsation and vibration, and thus reduce the noise level of the liquid reservoir and the compressor. When the other end of the suction pipe 30 is located in the second cavity 1201, due to the combination of the first cylinder 11 and the second cylinder 12, the height of the second cylinder 12 is usually less than the height of the conventional liquid reservoir, which also shortens the length of the suction pipe 30, thereby helping to reduce the suction resistance and suction fluctuations. When the other end of the straw 30 is located in the first cavity 1101, since the central axis of the first cylinder 11 is located on the side of the central axis of the second cylinder 12 close to the structure to be installed, the arrangement of the straw 30 can better make the center of gravity of the liquid reservoir closer to the structure to be installed, thereby increasing the stability of the liquid reservoir.

[0076] Specifically, the suction tube 30 is a straight tube.

[0077] Specifically, the suction pipe 30 is a steel pipe.

[0078] In the first or third embodiment, there are at least two suction pipes 30 and at least two outlets 121, and the at least two suction pipes 30 and the at least two outlets 121 are arranged one by one; the other ends of the at least two suction pipes 30 are located in the second cavity 1201. With such a structural arrangement, the suction path of the refrigerant is increased, the suction efficiency is improved, and the refrigerant can be better distributed, avoiding the air flow turbulence and noise caused by the excessive suction volume of the single outlet 121. At the same time, the other ends of all the suction pipes 30 are located in the second cavity 1201. Since the second cavity 1201 is located at the lower part of the liquid reservoir, which is the main area for the deposition of refrigerant liquid, the gas is sucked in through multiple suction pipes 30, which can effectively avoid the suction of liquid refrigerant, reduce the risk of liquid hammer, and protect the compressor.

[0079] In the second embodiment, there are at least two straws 30 and at least two outlets 121, and the at least two straws 30 and the at least two outlets 121 are arranged in a one-to-one correspondence. The other end of one of the at least two straws 30 is located in the first cavity 1101, and the other end of the other of the at least two straws 30 is located in the second cavity 1201. With such a structural arrangement, the other end of the other of the at least two straws 30 is located in the second cavity 1201, which can reduce the length of the straw 30 and thus reduce its own weight. The other end of one of the at least two straws 30 is located in the first cavity 1101, which can make the center of gravity of the liquid reservoir closer to the structure to be installed, thereby enhancing the setting stability of the liquid reservoir.

[0080] Specifically, in order to improve the air suction efficiency of the suction tube 30 and reduce the air suction resistance, the central axis of at least one of the two suction tubes 30 coincides with the central axis of the first cavity 1101 .

[0081] Specifically, the liquid reservoir also includes an inlet pipe 60, which is usually arranged on the first cylinder 11, one end of which is connected to the refrigerant supply pipeline of the refrigeration system through an external interface, and the other end extends into the inlet 111. This design ensures that the refrigerant can directly and quickly enter the gaseous refrigerant area of ​​the liquid reservoir, which is conducive to the initial stabilization of the gaseous refrigerant and the condensation of droplets. The position selection of the inlet pipe 60 should also avoid directly aligning with the filter assembly 20 to prevent the high-speed refrigerant from directly impacting the filter, causing damage to the filter or increasing the flow resistance, affecting the operating efficiency of the system.

[0082] Specifically, the liquid accumulator further includes an outlet pipe 70, which is located on the second cylinder 12, one end of which is connected to the air intake port of the compressor body 40 through an external interface, and the other end extends into the outlet 121. The outlet pipe 70 is located at a lower position of the second cylinder 12, and the outlet pipe 70 can ensure that the purest gaseous refrigerant is sucked into the compressor, avoiding the mixing of liquid refrigerant or liquid droplets, reducing liquid hammer, and protecting the compressor. At the same time, a certain distance is maintained between the outlet pipe 70 and the first cylinder 11 to ensure that the gaseous refrigerant has enough time and space to be fully separated and stabilized inside the liquid accumulator, thereby improving the efficiency of liquid-gas separation.

[0083] Specifically, the outlet pipe 70 is a curved pipe.

[0084] Specifically, in order to improve the circulation efficiency of the refrigerant, there are at least two outlet pipes 70 and at least two outlets 121 , and the at least two outlet pipes 70 and the at least two outlets 121 are arranged in a one-to-one correspondence.

[0085] Specifically, in any one of the embodiments from Example 1 to Example 3, the liquid reservoir eliminates the partition structure in the conventional liquid reservoir, making the internal space of the liquid reservoir more concise and smooth, reducing the impact of air flow pulsation when the liquid reservoir inhales on the internal structure, reducing the noise during its operation, and reducing unnecessary components, thereby reducing manufacturing difficulty and cost.

[0086] like Figure 4 As shown, a fourth embodiment of the present invention provides a compressor, which includes a liquid reservoir and a compressor body 40 provided in any one of embodiments 1 to 3, and the compressor body 40 forms a structure to be installed.

[0087] In the compressor provided by the fourth embodiment of the present invention, since the central axis of the first cylinder 11 is located on the side of the central axis of the second cylinder 12 close to the compressor body 40, and the maximum diameter of the first cylinder 11 is smaller than the minimum diameter of the second cylinder 12, this offset cylinder design helps to shift the center of gravity of the accumulator to the compressor body 40 side. At the same time, compared with the conventional accumulator structure, such a setting also effectively reduces the deadweight of the accumulator cylinder 10 through the small diameter setting of the first cylinder 11, thereby further making the center of gravity of the compressor closer to the center of gravity of the compressor body 40. The optimized adjustment of the center of gravity makes the center of gravity of the accumulator closer to the compressor body 40 when the accumulator is running, so that the center of gravity of the compressor is as close as possible to the center of gravity position of the compressor body 40, thereby reducing the influence of the connection between the accumulator and the compressor body 40 on the compressor body 40, effectively reducing the possibility of tilting and vibration of the compressor body 40, thereby reducing the possibility of vibration and tilting of the accumulator, and enhancing the stability and reliability of the system. Therefore, the compressor provided by this embodiment can solve the technical problem that the compressor in the prior art is prone to vibration during operation.

[0088] Specifically, the compressor further includes a connecting bracket 50. The first cylinder 11 is located above the second cylinder 12, and the second cylinder 12 of the liquid reservoir and the compressor body 40 are both connected to the connecting bracket 50. With such a structural arrangement, the use of the connecting bracket 50 not only ensures a stable connection between the liquid reservoir and the compressor body 40, but also facilitates the installation and maintenance of the entire compressor. By making the second cylinder 12 and the compressor body 40 both connected to the connecting bracket 50, since the first cylinder 11 is located above the second cylinder 12, such an arrangement can lower the overall center of gravity of the compressor, thereby reducing the possibility of tilting or vibration of the compressor during operation.

[0089] Specifically, the compressor also includes a connecting bracket 50. Among them, the first cylinder 11 is located on the side of the second cylinder 12 close to the structure to be installed, and the first cylinder 11 of the liquid reservoir and the compressor body 40 are both connected to the connecting bracket 50. With such a structural arrangement, the center of gravity of the liquid reservoir can be closer to the compressor body 40, which helps to optimize the overall center of gravity distribution of the compressor, reduce vibration and noise caused by center of gravity deviation, and enhance the stability of the compressor during operation. The optimization of the center of gravity not only reduces the risk of tilting during the operation of the compressor, but also improves the overall reliability of the refrigeration system. And such an arrangement makes the structure of the entire compressor more compact, which is conducive to improving the layout flexibility and space utilization efficiency of the equipment in a limited space.

[0090] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0091] 1. Make the overall center of gravity of the compressor close to the center of the circle of the bottom support foot of the compressor assembly to avoid the problem of compressor tilting or increased vibration when the compressor is running;

[0092] 2. Reduce the vibration generated when the compressor is running, and reduce the vibration of the liquid receiver caused by the liquid receiver steel pipe transmitted to the liquid receiver through the elbow connection;

[0093] 3. Reduce the periodic impact of air flow pulsation on the liquid reservoir, further avoiding the vibration of the liquid reservoir;

[0094] 4. The installation of the internal partition of the liquid reservoir is cancelled, which further avoids the vibration of the liquid reservoir;

[0095] 5. The volume of the liquid reservoir is reduced, the internal structure of the liquid reservoir is optimized, and the cost of the compressor is reduced.

[0098] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0099] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0100] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
