Description

Technical Field

[0001] This application relates to the field of compressor technology, and more specifically, to a liquid distributor fixing structure, a rotary compressor, and an air conditioner. Background Technology

[0002] With the development of technology, air conditioners are widely used in daily life. Among them, rotary compressors are mainly used in household air conditioning systems. Currently, low-noise and low-vibration compressors are the mainstream trend in compressor development. The distributor is generally the component with the greatest vibration in the compressor. When the compressor is running at high speed, the refrigerant in the distributor moves extremely fast, which will generate very turbulent airflow impacts on the radial and axial sides of the distributor, causing the compressor to vibrate at different frequencies. At the same time, there is a certain contradiction between the miniaturization and weight reduction of compressors and the reduction of compressor vibration. Excessive vibration will affect the reliability of the compressor and cause excessive noise, resulting in a poor user experience.

[0003] Existing compressor vibration reduction solutions mostly involve increasing the mass of specific external parts of the compressor or adding additional vibration damping pads to the compressor distributor. These improvements can mostly only balance the radial vibration of the distributor, with little improvement on the axial vibration of the distributor. Furthermore, the added devices increase the installation difficulty of the compressor and require additional costs. Summary of the Invention

[0004] This application provides a distributor fixing structure, a rotary compressor, and an air conditioner. The distributor fixing structure includes both a radial constraint portion to restrict the radial movement of the distributor and an axial constraint portion to restrict its axial movement. This allows for the restriction of both radial and axial movement of the distributor. It is worth noting that since each distributor has a different natural frequency, the resonant frequency with the compressor also differs. In this application, by changing the position of the axial constraint portion relative to the radial constraint portion, the axially enclosing area of ​​the axial constraint portion can enclose and press against different positions on the top and / or bottom spherical surfaces of the distributor, thereby changing the natural frequency of the distributor and preventing resonance between the distributor and the compressor. Specifically:

[0005] The first aspect of this application provides a distributor fixing structure for mounting on the housing of a compressor and fixing the compressor's distributor. The distributor fixing structure includes:

[0006] The radial constraint portion forms a radially encircling region, which is used to encircle and press against the outer peripheral surface of the dispenser to restrict the movement of the dispenser in the radial direction.

[0007] The axial constraint portion forms an axially enclosing region, which is used to enclose and press against the spherical surface of the top and / or bottom of the dispenser to restrict the movement of the dispenser in the axial direction.

[0008] The position of the axial constraint portion relative to the radial constraint portion can be adjusted so that the axially encircling area of ​​the axial constraint portion can encircle and press against different positions on the top and / or bottom spherical surfaces of the dispenser.

[0009] In the above technical solution, the radial constraint portion includes a connecting side close to the compressor housing and a non-connecting side away from the compressor housing;

[0016] Multiple connection points are formed on both axial supports. By changing the connection points of the axial pressure plate on the axial supports, the tilt angle of the axial pressure plate relative to the radial pressure plate can be changed, so that the axial encircling area formed by the axial pressure plate and the two axial supports can encircle and press against different positions on the top and / or bottom spherical surface of the dispenser.

[0017] In the above technical solution, the radial support includes an arc-shaped frame for cooperating with the housing wall of the compressor, and two radially bent frames formed at both ends of the arc-shaped frame in the length direction and in a bent shape. The two radially bent frames are symmetrical about the center position of the arc-shaped frame, and the radial pressure plate is an arc-shaped plate connected between the two radially bent frames.

[0018] Two axial supports are obliquely connected to two radially bent frames in a one-to-one correspondence, and are symmetrical about the center position of the arc frame, wherein the axial pressure plate is an arc plate connected between the two axial supports.

[0019] In the above technical solution, the two axial supports include a first axial support and a second axial support, and multiple connection points are formed on both the first axial support and the second axial support.

[0020] Multiple connection points on the first axial support and multiple connection points on the second axial support are divided into first mounting position, second mounting position, ... nth mounting position according to their height position;

[0021] The axial pressure plate, by being connected to different mounting positions, can change the tilt angle of the axial pressure plate relative to the radial pressure plate, so that the axial encircling area formed by the axial pressure plate and the two axial supports can encircle and press against different positions on the top and / or bottom spherical surface of the dispenser.

[0022] In the above technical solution, both axial supports are bent to form multiple support segments;

[0023] Each support segment has a connection point.

[0024] In the above technical solution, the axial support has multiple support segments that sequentially include a first support segment, a second support segment, ..., an nth support segment, from the side closest to the radial support to the side furthest from the radial support.

[0025] The inclination angle of the first support segment gradually decreases to that of the nth support segment, and an angle γ is formed between two adjacent support segments, which satisfies: 0°≤γ≤15°.

[0026] In the above technical solution, one of the two axial supports has a slot-type connection point, and the other has a bolt hole-type connection point.

[0027] One end of the axial pressure plate is engaged with a slotted connection point along its length, and the other end is threadedly connected to a bolt hole connection point.

[0028] In the above technical solution, the radial bracket has a groove at one end and a bolt hole at the other end in its length direction;

[0029] One end of the radial pressure plate is engaged with the slot of the radial bracket along its length, and the other end is threadedly engaged with the bolt hole of the radial bracket via a bolt.

[0030] In the above technical solution, the total height of the radial support and the axial support is H1, and the height of the axial support is h1.

[0031] Where h1 satisfies: 0.3H1≤h1≤0.5H1.

[0032] A second aspect of this application provides a rotary compressor, comprising:

[0033] chassis;

[0034] The dispenser and the dispenser fixing structure provided in the first aspect of the embodiments of this application, wherein the dispenser is fixed to the housing wall of the machine casing by the dispenser fixing structure;

[0035] The radial constraint portion of the distributor fixing structure surrounds and presses against the outer circumferential surface of the distributor to restrict the movement of the distributor in the radial direction, and the axial constraint portion of the distributor fixing structure surrounds and presses against the spherical surface of the top and / or bottom of the distributor to restrict the movement of the distributor in the axial direction.

[0036] In the above technical solution, the pump body of the rotary compressor is located in the bottom area of ​​the compressor;

[0037] The dispenser includes a lower spherical surface located near the pump body and an upper spherical surface located away from the pump body;

[0038] The axial constraint part of the separator fixing structure can wrap around and press against different positions on the spherical surface of the separator.

[0039] In the above technical solution, an inlet is provided at the middle position of the upper spherical surface of the separator, and an outlet is provided at the middle position of the lower spherical surface of the separator. The inlet is connected to a first pipeline, and the outlet is connected to one end of a second pipeline. The other end of the second pipeline is connected to the compression chamber of the pump body.

[0040] The upper spherical surface of the separator includes a first part of the upper spherical surface and a second part of the upper spherical surface that are symmetrical about the inlet. The first part of the upper spherical surface is located close to the compressor housing, and the second part of the upper spherical surface is located away from the compressor housing.

[0041] The axial constraint part of the distributor fixing structure can be wrapped around and pressed against different positions on the spherical surface of the second part of the distributor.

[0042] In the above technical solution, the radial constraint part of the distributor fixing structure radially constrains the area above the middle of the distributor, and the radial constraint part of the distributor fixing structure is spaced apart from the upper spherical surface of the distributor.

[0043] A third aspect of this application provides an air conditioner that includes the rotary compressor provided in the second aspect of this application.

[0044] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0045] The distributor fixing structure in this embodiment not only has a radial constraint portion that restricts the radial movement of the distributor, but also an axial constraint portion that restricts the axial movement of the distributor. Therefore, it can restrict the distributor's movement in both the radial and axial directions. It is worth noting that since each distributor has a different natural frequency, its resonant frequency with the compressor is also different. In this embodiment, by changing the position of the axial constraint portion relative to the radial constraint portion, the axially encircling area of ​​the axial constraint portion can encircle and press against different positions on the top and / or bottom spherical surfaces of the distributor, thereby changing the distributor's natural frequency and preventing resonance between the distributor and the compressor.

[0063] Background Introduction

[0064] Existing compressor vibration reduction solutions mostly involve increasing the mass of specific external parts of the compressor or adding additional vibration damping pads to the compressor distributor. These improvements can mostly only balance the radial vibration of the distributor, with little improvement on the axial vibration of the distributor. Furthermore, the added devices increase the installation difficulty of the compressor and require additional costs.

[0065] Example 1

[0066] Based on this, such as Figures 1-5 As shown, Embodiment 1 of this application provides a distributor fixing structure for mounting on the housing of a compressor and fixing the compressor's distributor. The distributor fixing structure includes:

[0067] The radial constraint portion 100 forms a radially enclosing region, which is used to enclose and press against the outer peripheral surface of the dispenser to restrict the movement of the dispenser in the radial direction.

[0068] The axial constraint portion 200 forms an axially enclosing region for enclosing and pressing against the spherical surface of the top and / or bottom of the dispenser to restrict the movement of the dispenser in the axial direction.

[0069] The position of the axial constraint portion 200 relative to the radial constraint portion 100 can be adjusted so that the axially encircling area of ​​the axial constraint portion 200 can encircle and press against different positions on the top and / or bottom spherical surface of the dispenser.

[0070] The distributor fixing structure in this embodiment not only has a radial constraint portion 100 that restricts the radial movement of the distributor, but also an axial constraint portion 200 that restricts the axial movement of the distributor. This allows for the restriction of both radial and axial movement of the distributor. It is worth noting that since each distributor has a different natural frequency, its resonant frequency with the compressor also differs. In this embodiment, by changing the position of the axial constraint portion 200 relative to the radial constraint portion 100, the axially encircling region of the axial constraint portion 200 can encircle and press against different positions on the top and / or bottom spherical surfaces of the distributor, thereby changing the natural frequency of the distributor and preventing resonance between the distributor and the compressor.

[0071] In this embodiment, the position of the axial constraint portion 200 of the distributor fixing structure is adjustable. This means that the axial constraint portion 200 can be adjusted according to the specific size and shape of the distributor and the specific requirements of the compressor to achieve the best fixing effect. This adjustability improves the adaptability and flexibility of the fixing structure. By adjusting the position of the axial constraint portion 200, the natural frequency of the distributor can be changed, thereby avoiding resonance between the distributor and the compressor. This is crucial for reducing noise and extending the service life of the compressor.

[0072] Furthermore, in some possible implementations, the radial constraint portion 100 includes a connecting side closer to the compressor housing and a non-connecting side farther from the compressor housing.

[0073] One end of the axial constraint portion 200 is connected to the connecting side of the radial constraint portion 100, and the other end extends obliquely toward the non-connecting side of the radial constraint portion 100.

[0074] The tilt angle of the axial constraint portion 200 can be adjusted so that the axially encircling area of ​​the axial constraint portion 200 can encircle and press against different positions on the top and / or bottom spherical surface of the dispenser.

[0075] The inclined extension of the axial constraint portion 200 in this embodiment can provide a better fixing effect because it can fit more closely to the spherical surface of the dispenser, thereby more effectively restricting the axial movement of the dispenser. Furthermore, the inclined angle of the axial constraint portion 200 is adjustable, which means that the inclined angle of the axial constraint portion can be adjusted according to the specific position and shape of the dispenser and the specific requirements of the compressor to achieve the best fixing effect.

[0076] Furthermore, in some possible implementations, the axial constraint portion 200 has an inclination angle of A relative to the radial constraint portion 100;

[0077] The preferred angle A is 30°≤A≤80°.

[0078] It should be noted that, in the embodiments of this application, the axial constraint portion 200 and the radial constraint portion 100, when projected onto the side, generally form a straight line. The inclination angle of the axial constraint portion 200 relative to the radial constraint portion 100, which is between 30° and 80°, refers to the included angle formed by the two portions after being projected onto the side. It should also be noted that the straight line formed by the axial constraint portion 200 and the radial constraint portion 100 after being projected onto the side does not need to be a perfectly straight line; it only needs to be generally straight.

[0079] Furthermore, in some possible embodiments, 4. the dispenser fixing structure according to any one of claims 1-3, characterized in that,

[0080] The radial constraint portion 100 includes a radial support 101 and a radial pressure plate 102. The radial support 101 is used to mate with the compressor housing, and the radial support 101 has a radial opening on the side away from the compressor housing. The radial pressure plate 102 is connected to the radial opening of the radial support 101 and surrounds the radial opening to define a radial encircling area between itself and the radial support 101.

[0081] The axial constraint portion 200 includes two axial supports 201 and an axial pressure plate 202. One end of each of the two axial supports 201 is connected to both ends of the radial opening of the radial support 101, and the other end extends obliquely toward the radial pressure plate 102. Both ends of the axial pressure plate 202 are connected to the extended ends of the two axial supports 201 and define an axial encircling area between the two axial supports 201.

[0082] Each of the two axial supports 201 has multiple connection points 2011. By changing the connection points of the axial pressure plate 202 on the axial support 201, the tilt angle of the axial pressure plate 202 relative to the radial pressure plate 102 can be changed, so that the axial encircling area formed by the axial pressure plate 202 and the two axial supports 201 can encircle and press against different positions on the top and / or bottom spherical surface of the dispenser.

[0083] In this embodiment, the radial support 101 and radial pressure plate 102 together define a radial encircling region, while the axial support 201 and axial pressure plate 202 together define an axial encircling region. This design allows for more precise control of the distributor's radial and axial constraints, thereby more effectively limiting the distributor's vibration. By forming multiple connection points 2011 on the axial support 201, the tilt angle of the axial pressure plate 202 relative to the radial pressure plate 102 can be changed. This design provides more adjustment options, allowing the fixing structure to adapt to the spherical surface of the distributor in different positions and shapes. Simultaneously, by adjusting the tilt angle of the axial pressure plate, the natural frequency of the distributor can be changed, thereby reducing the possibility of resonance with the compressor, reducing noise, and increasing the compressor's service life.

[0084] Furthermore, in some possible embodiments, the radial support 101 includes an arc-shaped frame 1011 for cooperating with the housing wall of the compressor, and two radially bent frames 1012 formed at both ends of the arc-shaped frame 1011 in the length direction and in a bent shape. The two radially bent frames 1012 are symmetrical about the center position of the arc-shaped frame 1011, wherein the radial pressure plate 102 is an arc-shaped plate connected between the two radially bent frames 1012.

[0085] Two axial supports 201 are obliquely connected to two radially bent supports 1012 in a one-to-one correspondence and are symmetrical about the center position of the arc-shaped support 1011, wherein the axial pressure plate 202 is an arc-shaped plate connected between the two axial supports 201.

[0086] In this embodiment, the symmetrical radial bending frame and axial support design enable a more uniform distribution of the entire fixing structure, which helps improve the stability and balance of the structure. Simultaneously, the fit between the arc-shaped frame and the compressor housing wall, along with the bending design of the radial bending frame, allows the fixing structure to fit more tightly against the compressor housing. Furthermore, the design of the arc-shaped frame and arc plate provides a larger contact area, which helps improve the strength and durability of the fixing structure, especially when subjected to distributor vibration. At the same time, the symmetrical design simplifies the manufacturing and assembly process, as symmetrical components can be manufactured using the same mold, reducing manufacturing complexity and cost. Moreover, the symmetrical connection between the axial support and the radial bending frame provides multiple adjustment points, allowing the position and tilt angle of the axial pressure plate to be adjusted as needed, improving the adjustment flexibility of the fixing structure.

[0087] Furthermore, in some possible implementations, the two axial supports 201 include a first axial support and a second axial support, and a plurality of connection points 2011 are formed on both the first axial support and the second axial support.

[0088] The multiple connection points 2011 on the first axial support and the multiple connection points 2011 on the second axial support are divided into first mounting position, second mounting position, ... nth mounting position according to their height position;

[0089] The axial pressure plate 202 can be connected to different mounting positions to change the tilt angle of the axial pressure plate 202 relative to the radial pressure plate 102, so that the axial encircling area formed by the axial pressure plate 202 and the two axial supports 201 can encircle and press against different positions on the top and / or bottom spherical surface of the dispenser.

[0090] In this embodiment, multiple connection points are formed on the first and second axial supports, and these points are divided into different mounting positions according to height. This design allows the axial pressure plate to be adjusted in height in the vertical direction to accommodate the spherical surface of the distributor at different heights. By changing the mounting position of the axial pressure plate, the tilt angle of the axial pressure plate relative to the radial pressure plate can be adjusted. This adjustment capability allows the fixing structure to better adapt to the specific shape and position of the distributor, improving the fixing effect. Multiple mounting positions provide more fixing options, allowing the axial pressure plate to be precisely positioned at the optimal position on the spherical surface of the distributor to achieve the best fixing effect. That is, by adjusting the tilt angle and position of the axial pressure plate, the vibration of the distributor can be more effectively controlled, reducing compressor noise and vibration, and improving overall performance.

[0091] It is worth noting that each of the above installation positions {first installation position, second installation position, ... nth installation position} includes two connection points 2011 at the same height. That is, the connection point 2011 at height h1 on the first axial support and the connection point 2011 at height h1 on the second axial support serve as the first installation position. Similarly, the connection point 2011 at height h2 on the first axial support and the connection point 2011 at height h2 on the second axial support serve as the second installation position, and so on up to the nth installation position.

[0092] Furthermore, in some possible implementations, one of the two axial supports has a slot-type connection point 2011 and the other has a bolt hole-type connection point 2011.

[0093] The axial pressure plate 202 is engaged with a slot-type connection point at one end along its length, and threadedly connected to a bolt hole-type connection point at the other end.

[0094] In this embodiment, two different connection methods are provided by forming slotted and bolt-hole connection points on the two axial supports respectively, increasing the flexibility and adaptability of the fixing structure. The slotted connection points allow for quick engagement and disengagement of the axial pressure plates, while the bolt-hole connection points provide a secure fixation. This design combines quick operation and stability, improving installation and maintenance efficiency. Simultaneously, the bolt-hole connection points provide strong fixing force through threaded connections, while the slotted connection points offer convenient positioning and fixation; the combination of both enhances the overall stability of the fixing structure.

[0095] Furthermore, in some possible embodiments, the radial bracket 101 has a slot formed at one end in its length direction and a bolt hole formed at the other end;

[0096] The radial pressure plate 102 is engaged with the slot of the radial bracket 101 at one end along its length, and the other end is engaged with the bolt hole of the radial bracket 101 by a bolt.

[0097] Furthermore, in some possible implementations, the total height of the radial support 101 and the axial support 201 is H1, and the height of the axial support 201 is h1.

[0098] Where h1 satisfies: 0.3H1≤h1≤0.5H1.

[0099] In this embodiment, by setting the ratio range of the axial support height h1 to the total height H1 to 0.3H1≤h1≤0.5H1, the rationality and balance of the fixed structure in spatial layout are ensured, which helps to achieve better mechanical distribution and structural stability. It is worth noting that, in order to effectively constrain the axial vibration of the distributor, the larger the horizontal angle A between the axial constraint part and the radial constraint part, the greater the axial constraint force. At the same time, for ease of processing and installation, the height of the axial support of the axial constraint part should not be greater than the height of the radial constraint part. Let the horizontal angle between the bent part and the radial constraint part be A, the height of the axial bent part be h1, and the total support height H1 be 0.3H1≤h1≤0.5H1. By adjusting the tilt angle of the axial pressure plate, the constraint position of the axial pressure plate on the distributor is changed, thereby changing the natural frequency of the distributor and avoiding resonance with the compressor. Preferably, the horizontal angle between the axial pressure plate and the radial pressure plate is 30°≤A<80°. Figure 4 As shown.

[0100] Furthermore, in a second aspect of embodiment 1 of this application, a rotary compressor is also provided, comprising:

[0101] Casing 300;

[0102] The dispenser 400 and the dispenser fixing structure provided in the first aspect of Embodiment 1 of this application are used to fix the dispenser 400 to the housing wall of the housing 300.

[0103] The radial constraint portion 100 of the distributor fixing structure surrounds and presses against the outer peripheral surface of the distributor 400 to restrict the movement of the distributor 400 in the radial direction, and the axial constraint portion 200 of the distributor fixing structure surrounds and presses against the spherical surface of the top and / or bottom of the distributor to restrict the movement of the distributor 400 in the axial direction.

[0104] Furthermore, in some possible implementations, such as Figure 5 As shown, the pump body of the rotary compressor is located in the bottom area of ​​the compressor;

[0105] The dispenser includes a lower spherical surface located near the pump body and an upper spherical surface located away from the pump body;

[0106] The axial constraint portion 200 of the distributor fixing structure can surround and press against different positions on the spherical surface of the distributor 400.

[0107] It is worth noting that since the pump body of the rotary compressor is located in the bottom area of ​​the compressor, the top of the distributor installed on the side of the compressor vibrates more. Based on this, in this embodiment, the axial constraint portion 200 of the distributor fixing structure is wrapped around and pressed against the upper spherical surface of the distributor, which has a better shockproof effect than wrapping the axial constraint portion 200 of the distributor fixing structure around and pressing against the lower spherical surface of the distributor.

[0108] Specifically, such as Figure 5 As shown, the middle position of the upper spherical surface of the distributor 400 is provided with an inlet, and the middle position of the lower spherical surface of the distributor 400 is provided with an outlet. The inlet is connected to a first pipeline, and the outlet is connected to one end of a second pipeline. The other end of the second pipeline is connected to the compression chamber of the pump body.

[0109] The upper spherical surface of the separator includes a first part of the upper spherical surface and a second part of the upper spherical surface that are symmetrical about the inlet. The first part of the upper spherical surface is located close to the compressor housing, and the second part of the upper spherical surface is located away from the compressor housing.

[0110] The axial constraint portion 200 of the distributor fixing structure can be wrapped around and pressed against different positions on the spherical surface of the second part of the distributor 400.

[0111] like Figure 5As shown, a second pipe connecting the distributor and the pump compression chamber is connected to the middle of the lower spherical surface of the distributor 400. Therefore, the bottom of the distributor 400 is supported, while the top of the distributor 400 is suspended. The vibration generated by the pump during operation is transmitted to the bottom of the distributor through the second pipe, and then from the bottom of the distributor to the top of the distributor. Therefore, the top of the distributor vibrates more. Based on this, in this embodiment, the axial constraint portion 200 of the distributor fixing structure surrounds and presses against the upper spherical surface of the distributor, which can effectively limit the vibration of the distributor at the position of maximum vibration.

[0112] Furthermore, in some possible embodiments, the radial constraint portion 100 of the distributor fixing structure radially constrains the region above the middle of the distributor 400, and the radial constraint portion 100 of the distributor fixing structure is spaced apart from the upper spherical surface of the distributor 400.

[0113] like Figure 5 As shown in the figure, and referring to the analysis above, the vibration of the distributor 400 is greatest in the top region. Therefore, by setting the radial constraint part of the distributor fixing structure in the region above the middle of the distributor 400, its constraint effect in the radial direction is more effective.

[0114] Furthermore, a third aspect of the present application also provides an air conditioner that includes the rotary compressor provided in the second aspect of the present application.

[0115] Furthermore, to better understand the design principles of the liquid distributor fixing structure, rotary compressor, and air conditioner in the embodiments of this application, the following will be combined with... Figures 1-5 Please provide a detailed explanation:

[0116] The compressor's distributor fixing structure includes a radial constraint portion 100 and an axial constraint portion 200, such as... Figure 1 As shown, the radial constraint part 100, through the radial pressure plate 102 and the rubber pad (not shown in the figure), can constrain the vibration of the distributor 400 in the radial direction to avoid the distributor 400 swinging left and right when the compressor is running; the axial constraint part 200 mainly constrains the vibration of the distributor 400 in the axial direction to reduce the vertical movement of the distributor 400 when the compressor is running.

[0117] In this embodiment, during the processing of the radial support 101 of the distributor fixing structure, an additional bending process is added, enabling the distributor support {radial support 101 and axial support 201} to function as a mounting and fixing point for two pressure plates {radial pressure plate 102 and axial pressure plate 202}. The radial pressure plate 102 is assembled in the same manner as in conventional assembly. The axial pressure plate 202 bypasses and presses against the spherical surface of the distributor's upper cover, and is locked onto the axial support 201 with self-tapping screws. This adds a flexible fulcrum for fixing the distributor, better securing it from multiple dimensions and achieving better vibration reduction. One end of the axial pressure plate 202 of the distributor fixing structure has a connecting hook, and one end of the axial support 201 of the distributor fixing structure has an installation port adapted to the connecting hook. The connecting hook engages with the installation port. The other end of the axial support 201 has a threaded mounting hole, and the second end of the axial pressure plate 202 has a through hole. The pressure plate is fixed to the bent portion with screws. In this embodiment of the application, when the operator needs to remove the liquid dispenser 400 from the mounting port, the operator can remove the connecting hook from the mounting port to release the liquid reservoir from its fixed state.

[0118] The side view of the liquid dispenser fixing structure in this embodiment is shown below. Figure 4 To effectively constrain the axial vibration of the distributor, the larger the horizontal angle A between the axial constraint part and the radial constraint part, the greater the axial constraint force. Simultaneously, for ease of processing and installation, the height of the axial support of the axial constraint part should not exceed the height of the radial constraint part. Let A be the horizontal angle between the bent part and the radial constraint part, h1 be the height of the axial bent part, and H1 be the total support height, where 0.3H1≤h1≤0.5H1. By adjusting the tilt angle of the axial pressure plate, the constraint position of the axial pressure plate on the distributor is changed, thereby altering the natural frequency of the distributor and preventing resonance with the compressor. Preferably, the horizontal angle between the axial pressure plate and the radial pressure plate is 30°≤A<80°.

[0119] In this embodiment of the application, the radial support 101 and the axial support 201 in the liquid dispenser fixing structure are integrally formed. Of course, in some possible technical solutions, the axial support 201 can also be connected to the radial support 101 by welding to more easily realize the installation pressure plate at different angles.

[0120] like Figure 2As shown, the axial support 201 is a single, non-bending support. Multiple connection points 2011 are directly mounted on this axial support 201. By setting mounting holes at different heights and inclination angles, modal analysis can be used to understand the vibration characteristics of the distributor. It can be found that the higher the position of the axial pressure plate 202, the higher the natural frequency of the distributor. When the distributor and compressor frequencies resonate, the pressure plate can be moved from a lower connection point to a higher connection point, thereby increasing the natural frequency of the distributor and avoiding resonance with the compressor. Alternatively, the pressure plate can be moved from a higher connection point to a lower connection point, thereby decreasing the natural frequency of the distributor and also avoiding resonance with the compressor. Figure 5 As shown.

[0121] Example 2

[0122] The difference between this embodiment and embodiment 1 is that: in this embodiment, both axial supports 201 of the liquid dispenser fixing structure are bent to form multiple support segments 201a;

[0123] Each support segment 201a has a connection point 2011.

[0124] Specifically, the axial support 201 comprises multiple support segments 201a, from the side closest to the radial support 101 to the side furthest from the radial support 101, including a first support segment, a second support segment, ..., an nth support segment;

[0125] The tilt angle of the first support segment gradually decreases to the tilt angle of the nth support segment.

[0126] In this embodiment, the assembly of the dispenser pressure plate and bracket is shown in [reference needed]. Figure 4 In this embodiment, the axial support 201 is configured as a multi-segment structure, with each segment having an installation opening and an installation hole. Compared to Embodiment 1, Embodiment 2 places the installation holes on different support segments 201a, providing a larger space for each installation hole. Furthermore, by setting an included angle γ between the two bent sections, a larger pressure plate installation angle can be achieved. It is recommended that 0°≤γ≤15°; this allows for better installation of the pressure plate, as an excessively large angle γ would make installation difficult.
