Description

Technical Field

[0001] The present application relates to the technical field of compressors, and in particular to a liquid accumulator and a compressor assembly. Background Art

[0002] In refrigeration equipment such as air conditioners, the liquid receiver, also known as the gas-liquid separator, is a key component of the compressor assembly. The receiver performs functions such as filtration, liquid storage, pressure stabilization, and oil return. Refrigerant flows from the evaporator's outlet pipe, passes through the receiver, and then enters the compressor pump. Because the evaporator outlet copper pipes of air conditioning systems from different manufacturers vary in specifications, different receiver models must be produced to match them. This increases the number of compressor assembly models and reduces their versatility.

[0003] Related art provides a liquid reservoir comprising a tank body with an opening on one side and a first cover, wherein the tank body and the cover internally form a chamber; the open side of the first cover is rotatably and sealedly connected to the open side of the tank body, and further comprising a first tube and a second tube for connecting the chamber with the outside, wherein the first tube is provided on the first cover, and the second tube is provided on the tank body. The first tube is provided on the first cover and can rotate with the first cover, so that the positions of the first and second tubes relative to the tank body are adjustable to meet the needs of different installation methods.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] In the related art, only the positions of the first tube and the second tube relative to the tank body can be adjusted by rotating the first cover. However, for evaporator outlet copper tubes with various sizes and specifications, the versatility of the liquid storage device still needs to be improved.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

[0045] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0046] In combination Figures 1-3 As shown, the embodiments of the present disclosure provide a liquid accumulator 10, which comprises a middle cylinder 30 and an upper end cover assembly 20.

[0047] The upper end cover assembly 20 comprises an upper end cover 21 and an air inlet pipe 22, the air inlet pipe 22 is arranged in the upper end cover 21; the upper end cover 21 is arranged at one end of the middle cylinder 30 along the axial direction; wherein the upper end cover 21 is detachably connected with the middle cylinder 30, so that the upper end cover assembly 20 can be replaced.

[0048] The air inlet pipe 22 is arranged in the upper end cover 21 and is used to connect the inside of the upper end cover 21 with the outside. In different upper cover assemblies, the size of the air inlet pipe 22 can be different, the position of the air inlet pipe 22 in the upper end cover 21 can be different, and the structure type of the upper end cover 21 can also be different.

[0049] By adopting the liquid accumulator 10 provided in the embodiments of the present disclosure, the upper end cover assembly 20 of different sizes and types can be flexibly replaced through the detachable connection between the upper end cover 21 and the middle cylinder 30, so that the size of the air inlet pipe 22 of the liquid accumulator 10 or the position of the air inlet pipe 22 can be adjusted. Such a design enables the liquid accumulator 10 to be adapted to various different specifications of the outlet copper pipe of the evaporator, and better improves the versatility of the liquid accumulator 10.

[0050] Optionally, in combination with the upper end cover assembly 20 shown in Figure 2 and Figure 3 , the upper end cover assembly 20 includes a first upper end cover assembly 23 or a second upper end cover assembly 24; wherein the parameters of the first upper end cover assembly 23 and the second upper end cover assembly 24 are different.

[0051] The upper end cover assembly 20 includes the first upper end cover assembly 23 or the second upper end cover assembly 24. The first upper end cover assembly 23 and the second upper end cover assembly 24 are alternatively matched with the middle cylinder.

[0052] When the upper end cover assembly 20 is the first upper end cover assembly 23, the upper end cover 21 is a first upper end cover 231, the air inlet pipe 22 is a first air inlet pipe 232, the first air inlet pipe 232 is arranged in the first upper end cover 231, and the first upper end cover 231 is detachably connected with the middle cylinder 30.

[0053] When the upper end cover assembly 20 is the second upper end cover assembly 24, the upper end cover 21 is a second upper end cover 241, the air inlet pipe 22 is a second air inlet pipe 242, the second air inlet pipe 242 is arranged in the second upper end cover 241, and the second upper end cover 241 is detachably connected with the middle cylinder 30.

[0054] Optionally, the parameters of the first upper end cover assembly 23 and the second upper end cover assembly 24 are different, including that the sizes of the pipe openings of the first air inlet pipe 232 and the second air inlet pipe 242 are different.

[0055] The sizes of the pipe openings of the first air inlet pipe 232 and the second air inlet pipe 242 are different, which means that the inner diameters of the pipe openings of the first air inlet pipe 232 and the second air inlet pipe 242 are different. The inner diameter of the pipe opening of the first air inlet pipe 232 is shown as Figure 2 in the figure, and the inner diameter of the pipe opening of the second air inlet pipe 242 is shown as Figure 3As shown in L10, L1≠L10. The first upper end cover assembly 23 or the second upper end cover assembly 24 can be replaced according to the requirement, so as to adjust the distance between the radial center of the inlet pipe 22 and the radial center of the upper end cover 21 of the reservoir 10. When the second inlet pipe 242 is arranged at the radial center of the second upper end cover 241, the radial center of the second inlet pipe 242 and the radial center of the second upper end cover 241 are on the same radial center line, and L10 is 0 at this time.

[0056] Optionally, the parameters of the first upper end cover assembly 23 and the second upper end cover assembly 24 are different, including the distance between the radial center of the first inlet pipe 232 and the radial center of the first upper end cover 231 and the distance between the radial center of the second inlet pipe 242 and the radial center of the second upper end cover 241.

[0057] The distance between the radial center of the first inlet pipe 232 and the radial center of the first upper end cover 231 is as shown in L1. Figure 2 The distance between the radial center of the second inlet pipe 242 and the radial center of the second upper end cover 241 is as shown in L10. Figure 3 The distance between the radial center of the first inlet pipe 232 and the radial center of the first upper end cover 231 is as shown in L1.

[0058] In different models of compressor assemblies, the radial distance requirement between the inlet pipe 22 of the reservoir 10 and the exhaust pipe 71 of the compressor 70 is different. By adjusting the distance between the radial center of the inlet pipe 22 and the radial center of the upper end cover 21, the distance between the radial center of the inlet pipe 22 and the radial center of the exhaust pipe 71 of the compressor 70 can be changed, so as to improve the universality of the compressor assembly.

[0059] Different sizes and positions of the inlet pipe 22 can adapt to evaporator outlet copper pipes with different diameters and different connection distances, so that the same model of the reservoir 10 can adapt to more models of air conditioning systems, thereby improving the universality and applicability of the reservoir 10. By simply replacing the upper end cover assembly 20, the size or position of the inlet pipe 22 can be adjusted, and the reservoir 10 can meet the specific requirements of different air conditioning systems. In this way, the need for customizing the reservoir 10 for specific systems is reduced, and the production and maintenance costs are also reduced.

[0060] Optionally, in combination with Figure 1 and Figure 4As shown, the middle cylinder 30 includes an extended cylinder section 40 and a main cylinder section 33, one end of the extended cylinder section 40 is detachably connected to the upper end cover 21; the main cylinder section 33 is detachably connected to the other end of the extended cylinder section 40; wherein, when the extended cylinder section 40 is removed from between the upper end cover 21 and the main cylinder section 33, the main cylinder section 33 is suitable for being detachably connected to the upper end cover 21.

[0061] The relatively large volume inside the liquid storage tank 10 can act as a buffer for the refrigerant, thereby maintaining the stability of the suction pressure, reducing suction pulsation, and thus playing a role in stabilizing pressure.

[0062] The refrigerant filling amount of refrigeration systems such as air conditioners of different specifications is different. The middle cylinder 30 is configured as a detachable extension cylinder section 40 and a main cylinder section 33. By disassembling and assembling the extension cylinder section 40, the effective volume inside the middle cylinder 30 can be adjusted.

[0063] The upper end cover 21 is adapted to both the expansion barrel section 40 and the main barrel section 33. The upper end cover 21 can be detachably connected to the expansion barrel section 40, and the upper end cover 21 can also be detachably connected to the main barrel section 33.

[0064] When the extended barrel section 40 is connected between the upper end cap 21 and the main barrel section 33, the effective volume of the liquid reservoir 10 is increased. When the extended barrel section 40 is removed, the main barrel section 33 is connected to the upper end cap 21, reducing the effective volume of the liquid reservoir 10. This design allows the internal effective volume of the liquid reservoir 10 to be adjusted, allowing it to adapt to different specifications of air conditioners and other refrigeration systems, thereby improving the adaptability of the liquid reservoir 10.

[0065] The axial length of the extended barrel section 40 is as follows: Figure 4 As shown in L3. The effective volume of the liquid reservoir 10 can be adjusted accordingly to the size of the refrigeration system. According to the refrigerant filling volume requirements of the refrigeration system, by adjusting the axial length of the extended barrel section 40, the volume of the liquid reservoir 10 can be obtained to match the refrigeration system.

[0066] Optionally, the extended barrel section 40 is threadedly connected to the main barrel section 33 ; and / or, the extended barrel section 40 is threadedly connected to the upper end cover 21 .

[0067] The extended barrel section 40 can be threadedly connected to the main barrel section 33, or it can be threadedly connected to the upper end cap 21. This application uses the example of the extended barrel section 40 being threadedly connected to both the main barrel section 33 and the upper end cap 21. The threaded connection is simple to operate and allows for quick disassembly and assembly of the extended barrel section 40, improving loading and unloading efficiency. Furthermore, the threaded connection provides a good sealing effect, preventing refrigerant leakage within the liquid reservoir 10.

[0068] Optionally, one of the extension cylinder segment 40 and the main cylinder segment 33 is provided with an inner thread, and the other is provided with an outer thread, the inner thread and the outer thread are matched to threadedly connect the extension cylinder segment 40 and the main cylinder segment 33. In this way, detachable connection between the extension cylinder segment 40 and the main cylinder segment 33 can be realized.

[0069] Optionally, one of the extension cylinder segment 40 and the upper end cover 21 is provided with an inner thread, and the other is provided with an outer thread, the inner thread and the outer thread are matched to threadedly connect the extension cylinder segment 40 and the upper end cover 21. In this way, detachable connection between the extension cylinder segment 40 and the upper end cover 21 can be realized.

[0070] Optionally, in combination with Figure 4 As shown in the drawings, the cylinder wall of the first end 44 of the extension cylinder segment 40 in the axial direction is provided with a first accommodation groove 441, the first accommodation groove 441 extends along the circumferential direction of the extension cylinder segment 40, the inner diameter of the upper end cover 21 is matched with the outer diameter of the first accommodation groove 441, so that when the extension cylinder segment 40 is connected to the upper end cover 21, the outer surface of the extension cylinder segment 40 is flush with the outer surface of the upper end cover 21.

[0071] The first end 44 of the extension cylinder segment 40 in the axial direction is provided with the first accommodation groove 441, so that the first end 44 of the extension segment in the axial direction can extend into the upper end cover 21. When connected, the first end 44 of the extension cylinder segment 40 can be closely matched with the upper end cover 21. The outer surface of the extension cylinder segment 40 is flush with the outer surface of the upper end cover 21, which can save external space occupation and improve the neatness and beauty of the overall appearance.

[0072] Optionally, in combination with Figure 4 As shown in the drawings, the cylinder wall of the second end 45 of the extension cylinder segment 40 in the axial direction is provided with a second accommodation groove 451, the second accommodation groove 451 extends along the circumferential direction of the extension cylinder segment 40, the inner diameter of the main cylinder segment 33 is matched with the outer diameter of the second accommodation groove 451, so that when the extension cylinder segment 40 is connected to the main cylinder segment 33, the outer surface of the extension cylinder segment 40 is flush with the outer surface of the main cylinder segment 33.

[0073] The second end 45 of the extension cylinder segment 40 in the axial direction is provided with the second accommodation groove 451, so that the second end 45 of the extension segment in the axial direction can extend into the main cylinder segment 33. When connected, the second end 45 of the extension cylinder segment 40 can be closely matched with the main cylinder segment 33. The outer surface of the extension cylinder segment 40 is flush with the outer surface of the main cylinder segment 33, which can save external space occupation and improve the neatness and beauty of the overall appearance.

[0074] Optionally, in combination with Figure 1 and Figure 4As shown, the extension cylinder segment 40 is configured with a first accommodating cavity 41, and the reservoir 10 further comprises a filter screen 42, which is arranged in the first accommodating cavity 41 and connected with the extension cylinder segment 40.

[0075] The filter screen 42 arranged in the first accommodating cavity 41 can prevent impurities from entering the reservoir 10, avoiding damage to the compressor assembly caused by impurities. The filter screen 42 is connected with the extension cylinder segment 40, and the extension cylinder segment 40 is detachably connected with the upper end cover 21 and the main cylinder segment 33, so that the filter screen 42 can be replaced or adjusted by detaching the extension cylinder segment 40. In this way, the maintenance efficiency of the filter screen 42 can be improved.

[0076] Optionally, in combination with Figure 1 and Figure 4 As shown, the extension cylinder segment 40 is configured with a first accommodating cavity 41, and the reservoir 10 further comprises a sound-absorbing structure 43, which is arranged in the first accommodating cavity 41 and connected with the extension cylinder segment 40.

[0077] The sound-absorbing structure 43 can effectively reduce the noise generated when the refrigerant flows in the reservoir 10. The sound-absorbing structure 43 is connected with the extension cylinder segment 40, and the extension cylinder segment 40 is detachably connected with the upper end cover 21 and the main cylinder segment 33, so that the sound-absorbing structure 43 can be replaced or adjusted by detaching the extension cylinder segment 40. In this way, the maintenance efficiency of the sound-absorbing structure 43 can be improved.

[0078] It can be understood that, in the case where the reservoir 10 is not provided with the extension cylinder segment 40, the filter screen 42 and the sound-absorbing structure 43 can also be arranged in the upper end cover 21 or the main cylinder segment 33.

[0079] Optionally, in combination with Figure 1 and Figure 5 As shown, the main cylinder segment 33 is configured with a second accommodating cavity 31, and the reservoir 10 further comprises an outlet pipe 50, which is arranged in the second accommodating cavity 31 and comprises a first pipe segment 51 and a second pipe segment 52 connected in series. The first pipe segment 51 extends along the axial direction of the middle cylinder 30, and the second pipe segment 52 is arranged at one end of the first pipe segment 51 facing the upper end cover 21 and is movably connected with the first pipe segment 51. The second pipe segment 52 can move towards or away from the upper end cover 21 relative to the first pipe segment 51, so that the length of the outlet pipe 50 is adjustable.

[0080] The outlet pipe 50 arranged in the second accommodating cavity 31 of the main cylinder segment 33 guides the flow of gaseous refrigerant. Since the axial end of the middle cylinder 30 can be replaced with different upper end cover assemblies 20, the adjustable length of the outlet pipe 50 enables the outlet pipe 50 to adapt to different upper end cover assemblies 20, avoiding interference between the outlet pipe 50 and the upper end cover assembly 20.

[0081] As Figure 5As shown, the length of the second pipe segment 52 is L2, i.e., the length of the air outlet pipe 50 can be adjusted in the range of L2.

[0082] In the case where the middle cylinder 30 comprises the extension cylinder segment 40 and the main cylinder segment 33 connected in communication, the filter screen 42 or the sound-absorbing structure 43 is arranged in the first cavity 41 of the extension cylinder segment 40, and the air outlet pipe 50 is arranged in the second cavity 31 of the main cylinder segment 33. The distance between the mounting center of the filter screen 42 or the sound-absorbing structure 43 and the upper end of the air outlet pipe 50 is shown as L4. Figure 4 The second pipe segment 52 is moved relative to the first pipe segment 51, so as to adjust the distance between the mounting center of the filter screen 42 or the sound-absorbing structure 43 and the upper end of the air outlet pipe 50, thereby preventing interference between the air outlet pipe 50 and the filter screen 42 or the sound-absorbing structure 43.

[0083] Optionally, in combination with Figure 1 and Figure 5 As shown, the second pipe segment 52 is sleeved outside the first pipe segment 51, and the second pipe segment 52 is in sliding connection with the first pipe segment 51 or the second pipe segment 52 is in threaded connection with the first pipe segment 51.

[0084] The sleeving connection mode of the second pipe segment 52 and the first pipe segment 51 can improve the connection stability between the first pipe segment 51 and the second pipe segment 52. The sliding connection between the second pipe segment 52 and the first pipe segment 51 enables the second pipe segment 52 to perform telescopic movement relative to the first pipe segment 51. The threaded connection between the second pipe segment 52 and the first pipe segment 51 enables the second pipe segment 52 to perform rotational movement relative to the first pipe segment 51. Both the sliding connection and the threaded connection can enable the air outlet pipe 50 to remain stable after the length adjustment, thereby preventing loosening of the connection between the first pipe segment 51 and the second pipe segment 52 due to vibration or pressure change.

[0085] Optionally, in combination with Figure 1 As shown, the liquid storage device 10 further comprises a fixing structure 32 connected between the first pipe segment 51 and the main cylinder segment 33. In this way, the first pipe segment 51 is fixedly connected to the main cylinder segment 33, thereby improving the stability of the air outlet pipe 50.

[0086] Optionally, in combination with Figure 1 As shown, the liquid storage device 10 further comprises a lower end cover 60 connected to one end of the main cylinder segment 33 away from the upper end cover 21; wherein the air outlet pipe 50 further comprises a third pipe segment 53 in communication with the first pipe segment 51, the third pipe segment 53 is arranged at one end of the first pipe segment 51 away from the upper end cover 21, and the third pipe segment 53 is arranged through the lower end cover 60.

[0087] The arrangement of the lower end cover 60 provides a sealed bottom for the liquid storage device 10. The arrangement of the third pipe segment 53 through the lower end cover 60 enables the air outlet pipe 50 to communicate with the outside from the bottom of the liquid storage device 10.

[0088] Optionally, in combination with Figure 1 As shown in FIG. 1, the first pipe section 51 extends as a straight pipe along the axial direction of the middle cylinder 30, and the third pipe section 53 extends as a bent pipe.

[0089] The first pipe section 51 is a straight pipe section of the gas outlet pipe 50, and extends linearly along the axial direction of the middle cylinder 30. The third pipe section 53 provides the gas outlet pipe 50 with the ability to change direction, so that the gas outlet pipe 50 can better adapt to the spatial layout between the liquid accumulator 10 and the compressor 70, facilitating the reasonable wiring of the pipeline.

[0090] Optionally, in combination with Figure 6 and Figure 7 As shown in FIG. 1, the present disclosure provides a compressor assembly, which comprises the compressor 70 and the liquid accumulator 10 as described in any one of the above embodiments.
