Description

Technical Field

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

[0002] The liquid accumulator is an indispensable component of the compressor. It is mainly used to separate the refrigerant returned from the refrigeration system into gas and liquid, and store liquid refrigerant and refrigeration oil at the same time to prevent the liquid refrigerant from being directly sucked into the compressor and causing liquid hammer, thereby ensuring the reliability of the compressor. It can be seen that the liquid accumulator plays a vital role in the performance of the compressor.

[0003] The accumulator typically consists of a cylindrical body, a long straight pipe connected to the accumulator's intake pipe, a curved pipe inside the cylinder, and a connecting pipe between the straight pipe and the compressor. These two pipes form the compressor's intake passage. As the compressor draws air through the accumulator, refrigerant gas exits the long straight pipe and enters the compressor's cylinder.

[0004] Usually, at least one partition is generally provided in the plane parallel to the radial direction of the cylinder in the inner cavity of the liquid reservoir cylinder. However, when the above-mentioned liquid reservoir partition is configured horizontally, the horizontal cavity mode of the liquid reservoir is closer to the structural mode, and it is easy to be excited, resulting in coupled resonance between the cavity and the structure, generating greater vibration and noise.

[0005] 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 the present invention, and therefore may include information that does not constitute prior art known to ordinary technicians in this field. Summary of the Invention

[0006] In response to the problems in the prior art, the purpose of the present invention is to provide a liquid reservoir and a compressor having the same, wherein the liquid reservoir has a partition with a three-dimensional conical structure. The partition of this structure prevents the coupling resonance between the liquid reservoir cavity and the structure, thereby reducing vibration noise.

[0007] Some embodiments of the present invention provide a liquid accumulator for a rotary compressor, the liquid accumulator comprising:

[0008] Cylinder;

[0009] an air inlet pipe, arranged at one end of the cylinder;

[0045] Figure 1 A schematic structural diagram of a liquid accumulator according to an embodiment of the present invention, which is used in a rotary compressor. Specifically, the liquid accumulator includes:

[0046] Cylinder 100;

[0047] The air inlet pipe 200 is provided at one end of the cylinder 100;

[0048] An air outlet pipe is provided at the other end of the cylinder 100, and the air outlet pipe includes an air outlet elbow 310 connected to the air intake of the compressor and an air outlet straight pipe 320 connected to the air outlet elbow and provided in the cylinder 100; and

[0049] The partition 400 is disposed inside the cylinder 100 . The partition 400 includes at least one three-dimensional conical structure. The straight air outlet pipe is disposed through the three-dimensional conical structure.

[0050] Figure 1 In the embodiment, the partition 400 includes a single three-dimensional conical structure, and the side view of the partition 400 is as shown in FIG. Figure 2 As shown, specifically, the three-dimensional conical structure includes a conical portion 440, a top portion 410 and a bottom portion 420. The conical portion 440 has two ends that are connected to the top portion 410 and the bottom portion 420, respectively. Optionally, the top portion 410 and the bottom portion 420 are cylindrical. When the partition 400 includes a single three-dimensional conical structure, the top portion 410 can be at the end of the air inlet pipe 200 of the liquid reservoir, as shown in FIG. Figure 1 It can also be at the end of the straight air outlet pipe 320 of the liquid reservoir.

[0051] In other embodiments, the partition 400 may also include two stacked three-dimensional conical structures, such as Figure 4 As shown, the air outlet straight pipe 320 is provided through two stacked three-dimensional cone structures. The two stacked three-dimensional cone structures can be integrated.

[0052] exist Figure 4 In the embodiment of the present invention, the partition 400 includes a three-dimensional conical structure with two bottoms 420 stacked on top of each other. Figure 5 The side view of the partition is shown; that is, the partition 400 is a structure formed by joining the bottoms 420 of two three-dimensional conical structures. Here, the conical portion 440 of the three-dimensional conical structure has a taper angle β. In actual use, the taper angle of the three-dimensional conical structure can be designed based on the size of the liquid reservoir barrel 100. Preferably, the taper angle β of the three-dimensional conical structure is between 30° and 120°.

[0053] In another embodiment, Figure 6 and Figure 7 As shown, the partition 400 comprises two three-dimensional conical structures with tops 410 stacked on top of each other, that is, the partition 400 is a structure formed by splicing the tops 410 of two three-dimensional conical structures. Similarly, the cone angle β of the three-dimensional conical structure can be between 30° and 120°.

[0054] The partition 400 of the liquid storage device of the present method is a spliced ​​structure of two three-dimensional conical structures. The partition 400 of this structure divides the inner cavity of the liquid storage device cylinder 100 into multiple chambers, so that the sound waves can be fully reflected in the inner cavity of the cylinder 100, thereby reducing the noise accompanying the refrigerant entering the liquid storage device in the pipeline and reducing the airflow noise generated when the gaseous refrigerant flows in the liquid storage device.

[0055] The partition of the liquid reservoir of the present invention comprises a three-dimensional conical structure. Whether in a single three-dimensional conical structure, or in embodiments where two three-dimensional conical structures are stacked at their bottoms, or two three-dimensional conical structures are stacked at their tops, the straight air outlet pipe 320 extends through the bottom of the three-dimensional conical structure of the partition 400. The partition and the straight air outlet pipe 320 are fixedly connected via the bottom of the three-dimensional conical structure of the partition 400 and the straight air outlet pipe 320, thereby securing the partition 400 within the liquid reservoir barrel 100.

[0056] In some embodiments, the bottom of the three-dimensional conical structure of the partition 400 and the air outlet straight pipe 320 can be fixedly connected to each other by welding or interference fit.

[0057] In the above embodiment, the partition is fixedly connected to the air outlet straight pipe through the bottom of the three-dimensional conical structure, which can reduce the vibration of the partition when the compressor is running, reduce the noise generated by the vibration of the partition, and improve the stability and efficiency of the compressor operation.

[0058] In other embodiments, the top of the three-dimensional conical structure of the partition 400 is fixedly connected to the inner wall of the cylinder 100. Specifically, the top of the three-dimensional conical structure of the partition 400 and the inner wall of the cylinder 100 can be fixedly connected by welding; or the top of the three-dimensional conical structure of the partition 400 can be placed in an annular groove provided on the inner wall of the liquid reservoir cylinder 100.

[0059] The partition 400 may be fixed in the liquid storage cylinder 100 by a fixed connection between the bottom of the three-dimensional conical structure of the partition 400 and the air outlet straight pipe 320, or by a fixed connection between the top of the three-dimensional conical structure of the partition 400 and the inner wall of the cylinder 100, or by both of the above fixed connections to make the partition have a more stable structure.

[0060] The partition of the liquid reservoir of the present invention includes two stacked three-dimensional conical structures. Regardless of a single three-dimensional conical structure, or an embodiment in which the bottoms of two three-dimensional conical structures are stacked, or the tops of two three-dimensional conical structures are stacked, the top of the three-dimensional conical structure is in contact with the cylinder 100 of the liquid reservoir, which can enhance the strength of the cylinder 100 of the liquid reservoir.

[0061] In some embodiments, at least one through hole 430 is provided on the partition 400. In this embodiment, a plurality of through holes 430 are provided. The through holes 430 are evenly distributed along the radial direction of the three-dimensional conical structure. Figure 8 In the embodiment, the partition 400 is provided with four rows of through holes evenly distributed along the radial direction of the three-dimensional conical structure. The number of through holes can be set according to the actual use scenario. The shape of the through holes is not limited and can be circular, elliptical, oblong, or polygonal.

[0062] Still other embodiments of the present invention provide a compressor comprising the above-mentioned accumulator. When the accumulator is used together with the compressor in an air-conditioning system, the refrigerant mixture in the refrigerant flow path enters the accumulator through the air inlet pipe, and the refrigerant flows directly to the suction channel of the compressor formed by the outlet elbow 310 and the outlet straight pipe 320 of the accumulator and then exits the accumulator (enters the compressor). The partition of the accumulator comprises a three-dimensional conical structure, which can adjust the horizontal cavity mode of the accumulator so that the horizontal cavity mode avoids the structural mode, thereby reducing the coupled resonance between the accumulator cavity and the structure, thereby reducing the noise generated by the coupled resonance. The compressor of the present invention has higher stability and efficiency.

[0063] In summary, the present invention provides a liquid reservoir and a compressor having the same, wherein the liquid reservoir is used for a rotary compressor, comprising: a cylinder; an air inlet pipe, arranged at one end of the cylinder; an air outlet pipe, arranged at the other end of the cylinder, the air outlet pipe comprising an air outlet elbow connected to the air intake of the compressor and an air outlet straight pipe connected to the air outlet elbow and arranged in the cylinder; and a partition, wherein the partition comprises at least one three-dimensional conical structure, and the air outlet straight pipe is passed through the three-dimensional conical structure. The partition of the liquid reservoir of the present invention includes a three-dimensional conical structure, which can adjust the horizontal cavity mode of the liquid reservoir so that the horizontal cavity mode avoids the structural mode, reduces the coupling resonance between the liquid reservoir cavity and the structure, and reduces the vibration noise of the liquid reservoir due to the coupling resonance when the compressor is running. The compressor with the above-mentioned liquid reservoir runs more stably and with lower noise; at the same time, the partition is fixedly connected to the air outlet straight pipe through the bottom of the three-dimensional conical structure, which can reduce the vibration of the partition when the compressor is running, reduce the noise generated by the vibration of the partition, and improve the stability and efficiency of the compressor operation; in addition, the top of the three-dimensional conical structure of the partition is in contact with the cylinder of the liquid reservoir, which plays a role in enhancing the strength of the cylinder of the liquid reservoir.
