Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of scroll compressors, and particularly relates to a scroll compressor. BACKGROUND

[0002] The scroll compressor is a volumetric compression compressor, and the compression component is composed of a dynamic scroll plate and a static scroll plate. During the compression process, the relative revolution of the dynamic scroll plate and the static scroll plate forms continuous changes of the closed volume, so as to achieve the purpose of compressing the gas. The suction assembly is a core component in the scroll compressor, and mainly bears the input of the fluid. Due to the structural limitation of the pump body, the working state of the suction assembly often has more resistance loss. The large resistance loss not only reduces the performance of the compressor, but also may affect the reliability of the compressor. Effectively reducing the suction resistance loss can better improve the performance of the compressor.

[0003] The suction pipe of the scroll compressor is mostly arranged in the axial and radial directions. For the axial suction pipe, the suction cavity is arranged on the static scroll plate, and the suction pipe is inserted into the suction cavity along the axial direction of the static scroll plate. The bottom wall and the side wall of the existing suction cavity are basically in a right angle structure. When the fluid is sucked into the compression cavity through the suction pipe, it will impact the tooth bottom of the static scroll plate, causing large pressure loss.

[0004] In the prior art, an arc surface is arranged in the suction cavity to guide the flow. However, the force of the gas acting on the arc surface when entering the suction cavity is often in the radial direction of the static scroll plate, which is in one direction. This causes large vibration of the scroll compressor, which is not conducive to the stable operation of the scroll compressor.

[0005] How to reduce the vibration of the scroll compressor caused by the gas in the suction cavity is a technical problem to be solved at present. SUMMARY

[0008] In some embodiments, the spiral surface comprises a first flow guide portion capable of guiding gas to flow in a direction opposite to the center of the static scroll, and a second flow guide portion capable of guiding gas to flow in a tangential direction of the static scroll.

[0010] In some embodiments, a mounting shell is arranged in the suction chamber, the mounting shell is provided with an opening, the flow guide is arranged in the mounting shell, and the opening of the mounting shell is in communication with the inlet of the compression chamber.

[0011] In some embodiments, the end of the flow guide is located at the opening of the mounting shell, and the opening of the mounting shell is opposite to the inlet of the compression chamber.

[0012] In some embodiments, the flow guide further comprises a damping spring plate connected to the end of the flow guide, and the damping spring plate extends into the compression chamber.

[0013] In some embodiments, a second arc surface is arranged at the bottom of the suction chamber, and the second arc surface is capable of guiding gas to flow to the inlet of the compression chamber.

[0014] In some embodiments, the scroll compressor further comprises a suction pipe, when the mounting shell is arranged, the inlet of the mounting shell faces upward, and one end of the suction pipe inserted into the suction chamber abuts against the mounting shell.

[0017] By including the flow guide member with a spiral surface, when the gas passes through the spiral surface, the spiral surface guides the gas, so that the gas flows in an arc line shape in the suction cavity, the flow is smoother, the force of the gas on the static vortex disc in the suction cavity is along different directions, thereby reducing the vibration of the static vortex disc, and accordingly reducing the vibration of the scroll compressor.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative work belong to the scope of protection of the present application.

[0037] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0038] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0039] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0040] In existing scroll compressors, the suction copper pipe is arranged parallel to the axial direction of the stationary disc; such as Figures 13-15 As shown, fluid enters the intake channel from the intake port and then moves vertically downwards to the intake chamber. During this process, the airflow impacts the bottom of the intake chamber, causing drag loss. In addition to the impact loss, due to velocity differences and fluid stagnation, a vortex fluid is generated in the lower left corner near the wall. Influenced by this vortex fluid, the fluid in the intake chamber will flow back, causing intake loss. Figure 11 From the perspective of the suction path cross-section, the fluid enters the compression chamber in a straight line from the suction chamber. Subsequently, the fluid impacts the moving disc teeth, resulting in collision losses and causing instability in the moving disc's movement, which generates vibration. The existence of these factors causes compressor vibration, which generates noise, reduces suction efficiency, decreases cooling capacity, and lowers energy efficiency.

[0041] To address the aforementioned problems, this application provides a scroll compressor, in conjunction with [see also...]Figures 1-12 As shown in the figure, a scroll compressor comprises a static scroll 1, the static scroll 1 comprises helical static scroll teeth, two adjacent static scroll teeth form a compression chamber 3, the outermost end of the static scroll tooth and the adjacent static scroll tooth form the inlet of the compression chamber 3, the inlet of the compression chamber 3 is directed to the tangential direction of the static scroll 1, the outer edge of the static scroll 1 is provided with a suction chamber 4, the inlet of the suction chamber 4 is directed upward, the outlet of the suction chamber 4 is connected with the inlet of the compression chamber 3; the suction chamber 4 is provided with a flow guide member, the flow guide member comprises a spiral surface 504, the part of the gas entering the suction chamber 4 from the inlet of the suction chamber 4 is guided by the spiral surface 504 and then enters the compression chamber 3 along the tangential direction of the static scroll 1.

[0042] By comprising the spiral surface 504, when the gas passes through the spiral surface 504, the spiral surface 504 guides the gas, so that the gas flows in an arc shape in the suction chamber 4, the flow is smoother, the force of the gas on the static scroll in the suction chamber is along different directions, thereby reducing the vibration of the static scroll, and correspondingly reducing the vibration of the scroll compressor; since the static scroll 1 and the dynamic scroll 2 are engaged together, the part of the gas entering the suction chamber 4 from the inlet of the suction chamber 4 is guided by the spiral surface 504 and then enters the compression chamber 3 along the tangential direction of the static scroll 1, when the gas enters the compression chamber 3, the impact force of the gas on the dynamic tooth 201 of the dynamic scroll 2 is reduced. Specifically, first, compared with only one arc surface guiding the gas, by guiding the gas through the spiral surface 504 of the flow guide member, the spiral surface 504 will generate multiple forces on the gas in different directions, the resultant force of the multiple forces in different directions is smaller than the force generated by one arc surface on the gas, so that the impact force of the gas flow on the static scroll 1 is reduced, which is beneficial to improve the stability of the operation of the scroll compressor. Second, the gas entering the compression chamber 3 along the tangential direction of the static scroll 1 reduces the probability and intensity of collision between part of the gas and the tooth surface of the dynamic tooth 201 and the tooth surface of the static tooth 101; thereby reducing the vibration amplitude and frequency of the static scroll 1 and the dynamic scroll 2; third, the gas passes through the spiral surface 504, the kinetic energy and pressure loss of the gas are small, which is beneficial to improve the working performance of the scroll compressor; fourth, the spiral surface 504 guides the gas to reduce or even avoid the vortex of the gas at the right angle of the suction chamber 4, further avoids the backflow caused by the vortex of the gas, and reduces the suction resistance of the compressor.

[0043] Preferably, the spiral surface 504 comprises a first flow guide part and a second flow guide part, the first flow guide part can make the gas flow in a direction away from the center of the static scroll 1, and the second flow guide part can make the gas flow along the tangential direction of the static scroll 1.

[0044] As Figure 7 andFigure 8 As shown, the first flow guide part makes the gas flow in a direction opposite to the center of the static scroll 1, and correspondingly, the gas generates a force on the static scroll 1 towards the center of the static scroll 1. Considering that the suction cavity 4 is located at the outer edge of the static scroll 1, as shown, Figure 12 As shown, the support distance of the scroll compressor is L, L passes through the center of the scroll compressor, the distance is large, and the radial force of the gas on the scroll compressor makes it less likely to tip over, which is beneficial to improve the stability of the scroll compressor. The second flow guide part makes the gas flow along the tangential direction of the static scroll 1, so that the gas can enter the compression cavity 3 along the tangential direction of the static scroll 1.

[0045] Figure 9 The inclined surface formed by the spiral surface 504 in the static scroll 1 is opposite to the inclined surface formed by the spiral surface 504 in the static scroll 2, which makes the flow direction of the gas in the suction cavity 4 as shown, Figure 10 As shown, when the flow guide part 4 is arranged in the suction cavity 4, the gas first flows towards the center of the static scroll 1, and then flows into the compression cavity 3 along the tangential direction of the static scroll 1.

[0046] Preferably, as shown, Figure 6 The flow guide part further comprises a first arc surface 5012, which is connected with the first end of the spiral surface 504 along the flow direction of the gas, the first arc surface 5012 is a concave arc surface, and the first arc surface 5012 is opposite to the center of the static scroll 1. The first arc surface 5012 is opposite to the center of the static scroll 1, so that the gas flows away from the center of the static scroll 1 when passing through the first arc surface 5012.

[0047] In the projection of the axial direction of the static scroll 1, the length of the line passing through the center of the suction cavity 4 is the largest among the lines connecting any two points on the outer edge of the static scroll 1, and the inlet of the suction cavity 4 is upward. Therefore, by arranging the first arc surface 5012, the flow direction of the gas changes from the axial direction of the static scroll 1 to the direction away from the center of the static scroll 1 when the gas flows through the first arc surface 5012, which is beneficial to reduce the tipping torque generated by the gas when the flow direction changes from the axial direction of the static scroll 1 to the direction towards the center of the static scroll 1. Further, it is beneficial to improve the stability of the scroll compressor in operation.

[0048] Further, the first arc surface 5012 is connected with the spiral surface 504, which is beneficial to reduce the friction loss when the gas flows from the first arc surface 5012 to the spiral surface 504.

[0049] Preferably, as shown, Figure 1 and Figure 7As shown, the suction cavity 4 is provided with a mounting shell 503, the mounting shell 503 is provided with an opening, the flow guide is arranged in the mounting shell 503, and the opening of the mounting shell 503 is communicated with the inlet of the compression cavity 3.

[0050] By arranging the mounting shell 503, the flow guide is arranged in the mounting shell 503, and when mounting, the flow guide is only arranged in the mounting shell 503, and then the mounting shell 503 is arranged in the suction cavity 4, without changing the existing suction cavity 4, the existing scroll compressor can be improved, and the production efficiency of the scroll compressor is improved.

[0051] Further, the suction cavity 4 is cylindrical, and the circular pipe is clamped into the suction cavity 4 to be fixed. The opening of the mounting shell 503 penetrates the circular pipe in the axial direction of the circular pipe.

[0052] Preferably, the end of the flow guide is located at the opening of the mounting shell 503, and the opening of the mounting shell 503 is opposite to the inlet of the compression cavity 3.

[0053] When the gas enters the compression cavity 3 from the suction cavity 4, the width of the flow path of the gas in the suction cavity 4 is greater than that in the compression cavity 3, so that sufficient gas can enter the compression cavity 3, but this will cause the gas to collide with the inner wall of the suction cavity 4 during the flow from the suction cavity 4 to the compression cavity 3, resulting in slow gas flow and turbulent flow. By clamping the end of the flow guide into the opening of the mounting shell 503, the opening of the mounting shell 503 is opposite to the inlet of the compression cavity 3, so that the gas flowing along the flow guide can directly enter the compression cavity 3 without directly colliding with the scroll teeth of the static scroll 1, effectively reducing the vibration of the scroll compressor.

[0054] Preferably, the flow guide further comprises a damping spring, the damping spring is connected to the end of the flow guide, and the damping spring extends into the compression cavity 3.

[0055] After the gas enters the compression cavity 3 along the spiral surface 504, it continues to flow along the damping spring. The damping spring has a flow guiding effect on one hand, so that the gas can flow more smoothly in the compression cavity 3; on the other hand, since the dynamic scroll 2 is located below the static scroll 1, the damping spring can reduce the vibration of the gas in the axial direction of the scroll compressor, so as to reduce the impact of the gas on the bottom of the dynamic scroll 2 in the compression cavity 3, and improve the stability of the scroll compressor.

[0056] Preferably, as shown in Figure 11 As shown, the bottom of the suction cavity 4 is provided with a second arc surface 5022, and the second arc surface 5022 can guide the gas to flow to the inlet of the compression cavity 3.

[0057] The second arc surface 5022 is arranged at the bottom of the suction cavity 4, and the gas that fails to be guided by the spiral surface 504 is guided by the second arc surface 5022 and then enters the compression cavity 3, thereby further reducing the impact force and probability of the gas on the static scroll 1.

[0058] Preferably, as shown in Figure 1 and Figure 3 The scroll compressor further comprises a suction pipe 6, when the mounting shell 503 is arranged, the inlet of the mounting shell 503 faces upward, and the suction pipe 6 is inserted into the end of the suction cavity 4 and abuts against the mounting shell 503.

[0059] The end of the suction pipe 6 inserted into the suction cavity 4 abuts against the mounting shell 503, thereby fixing the mounting shell 503. By fixing the mounting shell 503 in the above manner, on the one hand, the mounting mode of the mounting shell 503 is simplified, and the production efficiency of the scroll compressor is improved; on the other hand, the outlet of the suction pipe 6 communicates with the inlet of the mounting shell 503, so that the gas in the suction pipe 6 can more smoothly enter the mounting shell 503, thereby reducing the flow resistance of the gas in the suction pipe 6 entering the mounting shell 503. When the mounting shell 503 is a circular pipe, the inner diameter of the circular pipe is the same as the inner diameter of the suction pipe 6, the suction pipe 6 abuts against the circular pipe, the inner wall of the suction pipe 6 abuts against the inner wall of the circular pipe, and the gas smoothly enters the circular pipe from the suction pipe 6, thereby reducing the flow resistance of the gas.

[0060] Preferably, as shown in Figure 6 The flow guide comprises a first flow guide 501 and a second flow guide 502 below the first flow guide 501, the first flow guide 501 comprises a first partition plate 5011 extending in the up-down direction, and the first partition plate 5011 divides the suction cavity into a first suction part and a second suction part in the radial direction of the static scroll 1; at least part of the gas entering the first suction part flows through the first flow guide 501, and at least part of the gas entering the second suction part flows through the second flow guide 502.

[0061] The guide vanes include two guide vanes arranged in sequence, the first guide vane 501 includes a first partition plate 5011, the first partition plate 5011 divides the gas entering the suction chamber 4 into a first part and a second part, part of the gas in the first part enters the compression chamber 3 through the first guide vane 501, and part of the gas in the second part enters the compression chamber 3 through the second guide vane 502. When a third guide vane or other guide structure is arranged below the second guide vane 502, the second guide vane 502 further includes a second partition plate 5021, the second partition plate 5021 divides the second part of the gas into a third part and a fourth part, part of the gas in the third part enters the compression chamber 3 through the second guide vane 502, and the fourth part of the gas flows downward, and part or all of the fourth part of the gas enters the compression chamber 3 through the third guide vane or other guide structure. By dividing the gas into multiple parts, the gas in multiple parts enters the compression chamber 3 through different guide vanes, which improves the smoothness of the gas flow.

[0062] Preferably, as shown in the projection of the axial direction of the static scroll 1, a line extending through the center of the inlet of the compression chamber 3 and along the tangential direction of the static scroll 1 is an intake center line P, and the center of the suction chamber 4 is arranged on the two sides of the intake center line P with the center of the static scroll 1. Figure 5 As shown in the projection of the axial direction of the static scroll 1, a line extending through the center of the inlet of the compression chamber 3 and along the tangential direction of the static scroll 1 is an intake center line P, and the center of the suction chamber 4 is arranged on the two sides of the intake center line P with the center of the static scroll 1.

[0063] Figure 5 As shown in the projection of the axial direction of the static scroll 1, a line extending through the center of the inlet of the compression chamber 3 and along the tangential direction of the static scroll 1 is an intake center line P, and the center of the suction chamber 4 is arranged on the two sides of the intake center line P with the center of the static scroll 1.

[0064] It is easy for those skilled in the art to understand that the advantageous technical features of the above-mentioned modes can be freely combined and superimposed without conflict.
