Description

Technical Field

[0001] The present application relates to the technical field of compressors, and in particular to a liquid distributor fixing structure, a rotary compressor and an air conditioner. Background Art

[0002] With the development of technology, air conditioners are widely used in daily life, among which rotary compressors are currently mainly used in household air-conditioning systems. Currently, low-noise vibration compressors are the mainstream trend in the development of compressors. The distributor is generally the component with the largest vibration in the compressor. When the compressor is running at high speed, the refrigerant in the distributor moves very fast, which will produce very turbulent air flow impact on the radial and axial directions of the distributor, causing the compressor to vibrate in different frequency bands. At the same time, there is a certain contradiction between the miniaturization and lightweight development of compressors and the reduction of compressor vibration. Excessive vibration will affect the reliability of the compressor and excessive noise will cause a poor user experience.

[0003] Most of the existing compressor vibration reduction solutions increase the mass of specific parts outside the compressor or add additional vibration-damping pads to the compressor distributor. Most of these improvement measures can only balance the radial vibration of the distributor, and have little improvement on the axial vibration of the distributor. In addition, the added devices increase the difficulty of compressor installation and require additional costs. Summary of the invention

[0063] Background

[0064] Most of the existing compressor vibration reduction solutions increase the mass of specific parts outside the compressor or add additional vibration-damping pads to the compressor distributor. Most of these improvement measures can only balance the radial vibration of the distributor, and have little improvement on the axial vibration of the distributor. In addition, the added devices increase the difficulty of compressor installation and require additional costs.

[0065] Example 1

[0066] Based on this, Figure 1-Figure 5 As shown, in a first aspect, embodiment 1 of the present application provides a liquid distributor fixing structure, which is used to be installed on a casing of a compressor and fix the liquid distributor of the compressor, and the liquid distributor fixing structure includes:

[0067] A radial constraint portion 100, the radial constraint portion 100 forms a radial embracing region, and the radial embracing region is used to embrace and press on the outer peripheral surface of the liquid dispenser to limit the movement of the liquid dispenser in the radial direction;

[0068] An axial restraining portion 200, the axial restraining portion 200 forms an axially embracing region, the axially embracing region is used to embrace and press on 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 restraining portion 200 relative to the radial restraining portion 100 can be adjusted so that the axial embracing region of the axial restraining portion 200 can embrace and press on different positions of the top and / or bottom spherical surfaces of the dispenser.

[0070] The fixed structure of the liquid dispenser in the embodiment of the present application not only has a radial constraint portion 100 for limiting the radial movement of the liquid dispenser, but also has an axial constraint portion 200 for limiting the axial movement of the liquid dispenser, so that it can not only limit the movement of the liquid dispenser in the radial direction, but also limit the movement of the liquid dispenser in the axial direction. It is worth noting that since the natural frequency of each liquid dispenser is different, the resonant frequency generated with the compressor is also different. In the embodiment of the present application, by changing the position of the axial constraint portion 200 relative to the radial constraint portion 100, the axial embracing area of ​​the axial constraint portion 200 can also be encircled and pressed on different positions on the top and / or bottom spherical surface of the liquid dispenser, thereby changing the natural frequency of the liquid dispenser, and then avoiding resonance between the liquid dispenser and the compressor.

[0071] The position of the axial constraint part 200 of the liquid distributor fixing structure in the embodiment of the present application is adjustable, which means that the axial constraint part 200 can be adjusted according to the specific size and shape of the liquid distributor and the specific requirements of the compressor to achieve the best fixing effect. This adjustment capability improves the adaptability and flexibility of the fixing structure. By adjusting the position of the axial constraint part 200, the natural frequency of the liquid distributor can be changed, thereby avoiding the resonance phenomenon between the liquid distributor and the compressor. This is very important for reducing noise and extending the service life of the compressor.

[0072] Further, in some possible implementations, the radially constrained portion 100 includes a connection side close to a compressor casing, and a non-connection side away from a compressor casing;

[0073] One end of the axial restraining portion 200 is connected to the connection side of the radial restraining portion 100, and the other end is inclinedly extended toward the non-connection side of the radial restraining portion 100;

[0074] The inclination angle of the axial restraining portion 200 can be adjusted so that the axial embracing area of ​​the axial restraining portion 200 can embrace and cover different positions on the top and / or bottom spherical surfaces of the dispenser.

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

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

[0077] The angle A preferably satisfies: 30°≤A≤80°.

[0078] It should be noted that the projections of the axial constraint portion 200 and the radial constraint portion 100 on the side mentioned in the embodiment of the present application are generally a straight line, and the inclination angle of the axial constraint portion 200 relative to the radial constraint portion 100 mentioned in the embodiment of the present application is between 30° and 80°, which refers to an angle formed between the two parts after the side projection. It should also be noted that the straight line presented by the axial constraint portion 200 and the radial constraint portion 100 after the side projection is not required to be a straight line, as long as it is generally linear.

[0079] Further, in some possible implementations, 4. The liquid dispenser fixing structure according to any one of claims 1 to 3 is characterized in that:

[0080] The radial restraining part 100 includes a radial support 101 and a radial pressure plate 102. The radial support 101 is used to cooperate with the casing of the compressor, and the radial support 101 is formed with a radial opening on a side away from the compressor casing. The radial pressure plate 102 is connected to the radial opening position of the radial support 101 and encloses the radial opening to define a radial embracing area between the radial support 101 and the radial pressure plate 102.

[0081] The axial restraining part 200 includes two axial supports 201 and an axial pressure plate 202. One end of the two axial supports 201 is correspondingly connected to the two ends of the radial opening of the radial support 101, and the other end is inclined to extend toward one side of the radial pressure plate 102. The two ends of the axial pressure plate 202 are correspondingly connected to the extended ends of the two axial supports 201 and define an axial embracing area between the two axial supports 201.

[0082] A plurality of connection points 2011 are formed on each of the two axial supports 201. By changing the connection points of the axial pressure plate 202 on the axial support 201, the inclination angle of the axial pressure plate 202 relative to the radial pressure plate 102 can be changed, so that the axial embracing area surrounded by the axial pressure plate 202 and the two axial supports 201 can be encircled and pressed on different positions on the top and / or bottom spherical surfaces of the dispenser.

[0083] The radial support 101 and the radial pressure plate 102 in the embodiment of the present application jointly define a radial embracing area, while the axial support 201 and the axial pressure plate 202 jointly define an axial embracing area. This design allows for more precise control of the radial and axial constraints of the dispenser, thereby more effectively limiting the vibration of the dispenser. By forming a plurality of connection points 2011 on the axial support 201, the inclination angle of the axial pressure plate 202 relative to the radial pressure plate 102 can be changed. This design provides more adjustment options, so that the fixed structure can adapt to the spherical surface of the dispenser in different positions and shapes. At the same time, by adjusting the inclination angle of the axial pressure plate, the natural frequency of the dispenser can be changed, thereby reducing the possibility of resonance with the compressor, reducing noise and increasing the service life of the compressor.

[0084] Further, in some possible implementations, the radial support 101 includes an arc frame 1011 for cooperating with the shell wall of the compressor, and two radial bending frames 1012 formed at both ends of the length direction of the arc frame 1011 and presenting a bent shape, the two radial bending frames 1012 are symmetrical about the center position of the arc frame 1011, wherein the radial pressure plate 102 is an arc plate connected between the two radial bending frames 1012;

[0085] The two axial supports 201 are connected to the two radial bending frames 1012 in a one-to-one manner and are symmetrical about the center position of the arc frame 1011 , wherein the axial pressure plate 202 is an arc plate connected between the two axial supports 201 .

[0086] In the embodiment of the present application, the symmetrical design of the radial bending frame and the axial support can make the distribution of the entire fixed structure more uniform, which helps to improve the stability and balance of the structure. At the same time, the coordination between the arc frame and the compressor housing wall, as well as the bending design of the radial bending frame, enable the fixed structure to fit the compressor casing more compactly. In addition, the design of the arc frame and the arc plate provides a larger contact area, which helps to improve the strength and durability of the fixed structure, especially when subjected to the vibration of the dispenser. At the same time, the symmetrical design can simplify the manufacturing and assembly process, because the symmetrical parts can be manufactured using the same mold, reducing manufacturing complexity and cost. The symmetrical connection between the axial support and the radial bending frame provides multiple adjustment points, so that the position and inclination angle of the axial pressure plate can be adjusted as needed, thereby improving the adjustment flexibility of the fixed structure.

[0087] Further, in some possible implementations, the two axial brackets 201 include a first axial bracket and a second axial bracket, and a plurality of connection points 2011 are formed on the first axial bracket and the second axial bracket;

[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 a first installation position, a second installation position, ... an nth installation position according to their height positions;

[0089] The axial pressure plate 202 can change the inclination angle of the axial pressure plate 202 relative to the radial pressure plate 102 by being connected to different installation positions, so that the axial surrounding area surrounded by the axial pressure plate 202 and the two axial brackets 201 can surround and press different positions on the top and / or bottom spherical surface of the dispenser.

[0090] In the embodiment of the present application, a plurality of connection points are formed on the first axial bracket and the second axial bracket, and are divided into different installation positions according to the height position. This design allows the axial pressure plate to be adjusted in height in the vertical direction to adapt to the spherical surface of the dispenser at different heights. By changing the installation position connected to the axial pressure plate, the inclination angle of the axial pressure plate relative to the radial pressure plate can be adjusted. This adjustment capability enables the fixed structure to better adapt to the specific shape and position of the dispenser and improve the fixing effect. Multiple installation positions provide more fixing options, so that the axial pressure plate can be accurately positioned at the optimal position of the spherical surface of the dispenser to achieve the best fixing effect. That is, by adjusting the inclination angle and position of the axial pressure plate, the vibration of the dispenser can be more effectively controlled, the noise and vibration of the compressor can be reduced, and the overall performance can be improved.

[0091] It is worth mentioning that each of the above-mentioned installation positions {the first installation position, the second installation position...the nth installation} includes two connection points 2011 at the same height, that is, the connection point 2011 at the height h1 on the first axial bracket and the connection point 2011 at the height h1 on the second axial bracket are used as the first installation position, and similarly, the connection point 2011 at the height h2 on the first axial bracket and the connection point 2011 at the height h2 on the second axial bracket are used as the second installation position, and so on to the nth installation position.

[0092] Further, in some possible implementations, one of the two axial supports is formed with a slot-type connection point 2011, and the other is formed with a bolt hole-type connection point 2011;

[0093] One end of the axial pressure plate 202 in the length direction is snap-fitted with a slot-type connection point, and the other end is threadedly connected with a bolt hole-type connection point.

[0094] In the embodiment of the present application, two different connection methods are provided by forming slot-type and bolt-hole-type connection points on the two axial brackets, respectively, thereby increasing the flexibility and adaptability of the fixed structure. The slot-type connection point allows the axial pressure plate to be quickly connected and disassembled, while the bolt-hole-type connection point provides a firm fixation. This design combines fast operation and stability, improving the efficiency of installation and maintenance. At the same time, the bolt-hole-type connection point provides a strong fixing force through a threaded connection, while the slot-type connection point provides convenient positioning and fixation. The combination of the two can improve the stability of the entire fixed structure.

[0095] Further, in some possible implementations, the radial bracket 101 is formed with a slot at one end in the length direction thereof and a bolt hole at the other end;

[0096] One end of the radial pressure plate 102 in the length direction is engaged with the slot of the radial bracket 101 , and the other end is threadedly engaged with the bolt hole of the radial bracket 101 through bolts.

[0097] Further, 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 the embodiment of the present application, by setting the ratio range of the height h1 of the axial support to the total height H1 to 0.3H1≤h1≤0.5H1, the rationality and balance of the fixed structure in the spatial layout are ensured, which helps to achieve better mechanical distribution and structural stability. It is worth noting that in order to effectively restrain the axial vibration of the dispenser, the larger the horizontal angle A of the axial constraint part relative to the radial constraint part, the greater the axial constraint force. At the same time, for the convenience 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. Assuming that the horizontal angle of the bending part relative to the radial constraint part is A, the height of the axial bending part is h1, and the total height of the bracket is H1, 0.3H1≤h1≤0.5H1, by adjusting the inclination angle of the axial pressure plate, the constraint position of the axial pressure plate on the dispenser is changed, thereby changing the natural frequency of the dispenser, thereby avoiding resonance with the compressor. The preferred horizontal angle of the axial pressure plate relative to the radial pressure plate is 30°≤A<80°, such as Figure 4 shown.

[0100] Furthermore, the second aspect of Embodiment 1 of the present application further provides a rotary compressor, comprising:

[0101] Housing 300;

[0102] The liquid dispenser 400 and the liquid dispenser fixing structure provided in the first aspect of Embodiment 1 of the present application, the liquid dispenser 400 is fixed to the housing wall of the housing 300 through the liquid dispenser fixing structure;

[0103] The radial constraint portion 100 of the dispenser fixing structure is pressed against the outer peripheral surface of the dispenser 400 to limit the movement of the dispenser 400 in the radial direction, and the axial constraint portion 200 of the dispenser fixing structure is pressed against the spherical surface of the top and / or bottom of the dispenser to limit the movement of the dispenser 400 in the axial direction.

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

[0105] The liquid distributor comprises a lower spherical surface arranged close to the pump body portion, and an upper spherical surface arranged away from the pump body portion;

[0106] The axial restraining portion 200 of the liquid dispenser fixing structure can embrace and cover different positions of the spherical surface of the liquid dispenser 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 position of the liquid distributor installed on the side of the compressor vibrates greatly. Based on this, in the embodiment of the present application, the axial constraint part 200 of the liquid distributor fixing structure is surrounded and pressed on the upper spherical surface of the liquid distributor. Compared with the axial constraint part 200 of the liquid distributor fixing structure being surrounded and pressed on the lower spherical surface of the liquid distributor, its shockproof effect is better.

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

[0109] The upper spherical surface of the liquid distributor comprises a first upper spherical surface and a second upper spherical surface symmetrical about the inlet, the first upper spherical surface is arranged close to the casing of the compressor, and the second upper spherical surface is arranged far from the casing of the compressor;

[0110] The axial restraining portion 200 of the liquid dispenser fixing structure can be pressed around different positions on the spherical surface of the second portion of the liquid dispenser 400 .

[0111] like Figure 5As shown, a second pipeline connecting the liquid separator and the compression chamber of the pump body is connected to the middle position of the lower spherical surface of the liquid separator 400, so that the bottom of the liquid separator 400 is supported and the top of the liquid separator 400 is in a suspended state, and the vibration generated by the pump body during operation is transmitted to the bottom of the liquid separator through the second pipeline, and then transmitted from the bottom of the liquid separator to the top of the liquid separator, so the top of the liquid separator vibrates greatly. Based on this, in the embodiment of the present application, the axial constraint part 200 of the liquid separator fixing structure is embraced and pressed on the upper spherical surface of the liquid separator, which can effectively limit the vibration of the liquid separator at the position of maximum vibration.

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

[0113] like Figure 5 As shown and referring to the above analysis, it can be known that the vibration of the dispenser 400 is the largest in the top area, so by setting the radial constraint part of the dispenser fixing structure in the area above the middle of the dispenser 400, the constraint effect in the radial direction is better.

[0114] Furthermore, the third aspect of the embodiment of the present application also provides an air conditioner, which includes the rotary compressor provided in the second aspect of embodiment 1 of the present application.

[0115] Further, in order to make the design principle of the liquid distributor fixing structure, rotary compressor and air conditioner in the embodiment of the present application clearer, the following is combined with Figure 1-Figure 5 To explain in detail:

[0116] The compressor liquid distributor fixing structure includes a radial constraint portion 100 and an axial constraint portion 200. Figure 1 As shown, the radial constraint part 100 can constrain the radial vibration of the liquid distributor 400 through the radial pressure plate 102 and the rubber pad {not shown in the figure} to prevent the liquid distributor 400 from swinging left and right when the compressor is running; the axial constraint part 200 is mainly used to constrain the axial vibration of the liquid distributor 400 to reduce the up and down movement of the liquid distributor 400 when the compressor is running.

[0117] In this embodiment, during the processing of the radial bracket 101 of the fixed structure of the dispenser, a bending process is added so that the dispenser bracket {radial bracket 101 and axial bracket 201} have the function of installing and fixing two pressure plates {radial pressure plate 102 and axial pressure plate 202}. The radial pressure plate 102 is the same as the conventional assembly, and the axial pressure plate 202 bypasses and presses on the spherical surface of the upper cover of the dispenser, and is locked on the axial bracket 201 with self-tapping screws. A flexible fulcrum is added to fix the dispenser, and the dispenser is better fixed in multiple directions to achieve a better vibration reduction effect. One end of the axial pressure plate 202 of the fixed structure of the dispenser has a connecting hook, and one end of the axial bracket 201 of the fixed structure of the dispenser has an installation port adapted to the connecting hook, and the connecting hook is buckled in the installation port. The other end of the axial bracket 201 has a threaded installation hole, and the second end of the axial pressure plate 202 has a through hole, and the pressure plate is fixed to the bending portion by screws. In the embodiment of the present application, when the operator needs to release the liquid dispenser 400 from being fixed, the operator can move the connecting hook out of the installation port to release the fixed state of the liquid reservoir.

[0118] The side view of the liquid dispenser fixing structure in the embodiment of the present application is as follows Figure 4 In order to effectively restrain the axial vibration of the dispenser, the larger the horizontal angle A of the axial restraining part relative to the radial restraining part, the greater the axial restraining force. At the same time, for the convenience of processing and installation, the height of the axial bracket of the axial restraining part should not be greater than the height of the radial restraining part. Assuming the horizontal angle of the bending part relative to the radial restraining part is A, the height of the axial bending part is h1, and the total height of the bracket is H1, 0.3H1≤h1≤0.5H1, by adjusting the inclination angle of the axial pressure plate, the restraining position of the axial pressure plate on the dispenser is changed, thereby changing the natural frequency of the dispenser, thereby avoiding resonance with the compressor. The preferred horizontal angle of the axial pressure plate relative to the radial pressure plate is 30°≤A<80°.

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

[0120] like Figure 2As shown, the axial bracket 201 is in the form of a single bracket without bending. At this time, multiple connection points 2011 are directly arranged on the axial bracket 201. By setting mounting holes with different inclination angles at different heights, the vibration characteristics of the liquid distributor can be understood through modal analysis. It can be found that the higher the position of the axial pressure plate 202, the higher the natural frequency of the liquid distributor. When the frequency of the liquid distributor and the compressor resonates, the pressure plate can be moved from a connection point at a low position to a connection point at a high position, thereby increasing the natural frequency of the liquid distributor and avoiding resonance with the compressor. The pressure plate can also be moved from a connection point at a high position to a connection point at a low position, thereby reducing the natural frequency of the liquid distributor and also avoiding resonance with the compressor. Figure 5 shown.

[0121] Example 2

[0122] The difference between this embodiment and embodiment 1 is that: the two axial brackets 201 of the liquid dispenser fixing structure in the embodiment of the present application are both bent to form a plurality of bracket segments 201a;

[0123] Each of the bracket segments 201a is provided with a connection point 2011 .

[0124] Specifically, the plurality of bracket segments 201a of the axial bracket 201 include a first bracket segment, a second bracket segment, ... an nth bracket segment in sequence from a side close to the radial bracket 101 to a side far away from the radial bracket 101;

[0125] The inclination angles of the first bracket segment to the nth bracket segment gradually decrease.

[0126] In this embodiment, the assembly of the dispenser pressure plate and the bracket is shown in FIG. Figure 4 In this embodiment, the axial support 201 is set to be multi-segmented, and each support segment is provided with a mounting opening and a mounting hole. Compared with embodiment 1, embodiment 2 sets the mounting holes on different support segments 201a, and the size space of each mounting hole is larger. Moreover, a larger pressure plate mounting angle can be achieved by setting an angle γ between the two bending portions, and it is recommended that 0°≤γ≤15°; the pressure plate can be better installed, and the pressure plate is difficult to install if the angle γ is too large.
