DETAILED DESCRIPTION
[0024] The following is a detailed description of the embodiments of the present invention. Although the present invention will be described and illustrated in conjunction with certain specific embodiments, it should be noted that the present invention is not limited to these embodiments. On the contrary, modifications or equivalent substitutions of the present invention are intended to fall within the scope of the claims of the present invention.
[0025] In addition, numerous specific details are provided in the following detailed description to better illustrate the present invention. Those skilled in the art will appreciate that the present invention can be practiced without these specific details. In other instances, well-known structures and components are not described in detail in order to highlight the main purpose of the present invention.
[0026] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments to make the characteristics and advantages of the present invention more apparent.
[0027] Please refer to Figure 1 and Figure 2 , which is a schematic diagram of the structure of the air outlet pipe of the liquid storage device according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, the liquid reservoir 10 includes: a cylinder 1, a partition 2, an air inlet pipe 3 and an air outlet pipe 4; the cylinder 1 has an inner cavity, the partition 2 is arranged in the inner cavity, and is connected to the cavity wall of the inner cavity to divide the inner cavity into a first inner cavity and a second inner cavity arranged along its axial direction (the numbers in the figure are not shown); one end of the cylinder 1 is provided with an air inlet interface connected to the first inner cavity (the numbers in the figure are not shown), and the air inlet pipe 3 is arranged at the air inlet interface and connected to the first inner cavity; the other end of the cylinder 1 is provided with an air outlet interface connected to the second inner cavity (the numbers in the figure are not shown), and the air outlet pipe 4 is arranged at the air outlet interface and connected to the second inner cavity; wherein, at least one flow hole 2a is provided on the partition 2, and the at least one flow hole 2a is arranged along the thickness direction of the partition 2 and passes through the partition 2.
[0028] Specifically, the air inlet pipe 3 is provided at one end of the cylinder 1, the air outlet pipe 4 is provided at the other end of the cylinder 1, and the partition plate 2 is provided inside the cylinder 1. Figure 1 As shown, the outer wall of the partition 2 is fixed to the inner wall of the cylinder 1 to divide the inner cavity into a first inner cavity and a second inner cavity arranged along its axial direction. The cylinder 1 is provided with an air inlet interface connected to the first inner cavity, one end of the air inlet pipe 3 extends into the first inner cavity, and the other end of the air inlet pipe 3 extends out of the cylinder 1. The cylinder 1 is also provided with an air outlet interface connected to the second inner cavity, one end of the air outlet pipe 4 extends into the second inner cavity, and the other end of the air outlet pipe 4 extends out of the cylinder.
[0029] Please continue to refer to Figure 1 and Figure 3, at least one through-hole 2a and at least one mounting hole 2b are provided on the partition 2, and the through-hole 2a and the mounting hole 2b maintain a preset distance. The through-hole 2a is used to suppress the upper and lower cavity modes of the liquid reservoir and reduce noise, and the mounting hole 2b is used to insert the air outlet pipe 4, and one end of the air outlet pipe 4 extends into the first inner cavity through the mounting hole 2b. In this embodiment, the air outlet pipe 4 is a double-tube structure. Accordingly, the partition 2 has two symmetrically arranged mounting holes 2b. As Figure 3 As shown, the distance between the two mounting holes 2b is L.
[0030] The number of the through holes 2a can be set according to the actual use scenario and is not limited here. The shape of the through holes 2a can be circular, elliptical, oblong or polygonal and is not limited here.
[0031] like Figure 3 As shown, in this embodiment, the partition plate 2 is provided with two symmetrically arranged flow holes 2a, and the distance between the two flow holes 2a is More preferably, the at least two through-holes 2a are located on the same circumference.
[0032] A simulation experiment was conducted on a compressor with two symmetrically arranged flow holes 2a on the partition 2, and a relationship curve between the ratio of the compressor noise offset frequency band to the original noise frequency band and the ratio of the total area of the flow holes 2a to the cross-sectional area of the cylinder 1 was obtained. Figure 4 As shown in the figure, the Y-axis direction shows the ratio of the noise offset frequency band of the liquid reservoir 10 to the original noise frequency band, and the X-axis direction shows the ratio of the total area of the flow holes 2a to the cross-sectional area of the cylinder 1. As the ratio of the total area of the flow holes 2a to the cross-sectional area of the cylinder 1 decreases, the ratio of the noise offset frequency band of the liquid reservoir 10 to the original noise frequency band increases, that is, the smaller the total area of the flow holes 2a, the greater the impact on the liquid reservoir cavity mode, and the more obvious the noise optimization effect.
[0033] Preferably, the ratio of the total area of the through holes 2a to the cross-sectional area of the cylinder 1 is less than 10%. Further, the ratio of the total area of the through holes 2a to the cross-sectional area of the cylinder 1 is less than 5%.
[0034] Accordingly, this embodiment further provides a compressor, which includes the above-mentioned liquid accumulator 10. Please refer to the above for details, which will not be repeated here.
[0035] In existing compressors, at least one partition is usually provided in the inner cavity of the liquid reservoir cylinder in a plane parallel to the radial direction of the cylinder. When the above-mentioned partition is arranged horizontally, the horizontal cavity mode of the liquid reservoir is close to the structural mode, which is easily excited, resulting in coupled resonance between the cavity and the structure, generating greater vibration and noise.
[0036] In the compressor provided in this embodiment, since the flow hole 2a is opened on the partition 2 of the liquid reservoir 10, the upper and lower cavity modes of the liquid reservoir can be suppressed during operation, thereby reducing the internal machine transmission sound and improving the user experience.
[0037] In summary, the liquid reservoir and compressor of the present invention, by providing flow holes on the partition of the liquid reservoir to suppress the cavity mode of the liquid reservoir, can effectively reduce noise and enhance the user experience.
[0038] The above content is a further detailed description of the present application in conjunction with specific preferred embodiments, and the specific implementation of the present application cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, and all of them should be considered to fall within the scope of protection of the present application.
