Description

Technical Field

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

[0002] Rotary compressors are widely used in refrigeration systems such as air conditioning, heat pumps, and freezing / refrigeration. The distributor is an essential component of the rotary compressor, playing a role in stabilizing pressure, separating oil and liquid, and filtering. The conventional design of compressors places the distributor on one side of the compressor. This arrangement not only increases the overall radial dimension of the compressor but also leads to a series of problems such as distributor swaying up and down and excessive refrigerant aerodynamic noise.

[0003] In existing technologies, to address these issues, most compressors place the distributor on the top, bottom, or inside of the compressor body, aiming to position the overall center of gravity along the compressor body's central axis. Based on the relative position of the distributor to the compressor body, they are broadly categorized as top-mounted distributors and bottom-mounted distributors. However, top-mounted distributors, located on the top of the compressor body, increase the overall axial dimension of the compressor and may cause the compressor to operate under low back pressure. Bottom-mounted distributors, located on the compressor body, also increase the overall axial dimension of the compressor. If placed inside the compressor body, they occupy the oil sump's volume; if placed outside, their hollow internal structure may not be able to support the weight of the compressor body, potentially causing damage. To solve these problems, a ring-shaped distributor is designed, fitted around the outside of the compressor body.

[0004] However, the existing annular distributor has the following problems: in order to achieve the pressure stabilization conditions of the compressor, increasing the cavity volume of the distributor increases the overall radial dimension of the compressor; in order to reduce the overall radial dimension of the compressor, the pressure stabilization conditions of the distributor cannot be achieved, and it may also be unable to achieve functions such as oil return, liquid separation and filtration.

[0005] In addition, existing liquid separators also suffer from excessive noise during operation.

[0006] Therefore, the existing compressor technology has a problem that the way the distributor is set cannot reduce the overall size of the compressor without affecting the effectiveness of the distributor. Summary of the Invention

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Please refer to Figures 1 to 6 The present invention provides a liquid separator suitable for compressor 1. Compressor 1 includes a housing 11. The liquid separator includes a liquid separator housing 23, a first protrusion 21 and a second protrusion 22. The liquid separator housing 23 is sleeved on the outside of the housing 11, and the liquid separator housing 23 and the housing 11 form a liquid separator chamber 3. The first protrusion 21 and the second protrusion 22 are arranged at intervals along the circumference of the liquid separator housing 23, and both the first protrusion 21 and the second protrusion 22 protrude from the outer circumferential surface of the liquid separator housing 23.

[0033] The first protrusion 21 has a first receiving cavity 211 and a first connecting hole that are interconnected. The liquid distribution housing 23 is provided with a first connecting opening for connecting the first receiving cavity 211 and the liquid distribution cavity 3. The first connecting hole is used to transport the gaseous refrigerant in the first receiving cavity 211 to the pump body 12 of the compressor 1. The second protrusion 22 has a second receiving cavity 221 and a second connecting hole 222 that are interconnected. The liquid distribution housing 23 is provided with a second connecting opening for connecting the second receiving cavity 221 and the liquid distribution cavity 3. The second connecting hole 222 is used to deliver refrigerant into the second receiving cavity 221.

[0034] This invention provides a liquid distributor suitable for a compressor 1. The compressor 1 includes a housing 11, and the liquid distributor includes a liquid distributor housing 23, a first protrusion 21, and a second protrusion 22. By providing a liquid distributor chamber 3 for gas-liquid separation of the refrigerant entering the chamber 3, a first connecting hole for conveying gaseous refrigerant from a first receiving chamber 211 to the pump body 12 of the compressor 1, and a second connecting hole 222 for conveying refrigerant into a second receiving chamber 221, the refrigerant entering the second receiving chamber 221 through the second connecting hole 222 undergoes gas-liquid separation in the liquid distributor chamber 3. The gaseous refrigerant then enters the first receiving chamber 211 and is subsequently conveyed to the pump body 12 of the compressor 1 through the first connecting hole. This prevents a large amount of liquid refrigerant from entering the pump body 12 and causing damage. Furthermore, the inclusion of the first and second protrusions 21 and 22 reduces the overall size of the liquid distributor, thus solving the problem in existing technologies where the liquid distributor cannot reduce the overall size of the compressor without affecting its performance.

[0035] Specifically, the shape and size of the first connecting opening are adapted to the shape and size of the connection between the liquid separator 23 and the first protrusion 21; the shape and size of the second connecting opening are adapted to the shape and size of the connection between the liquid separator 23 and the second protrusion 22; the liquid separator 23 is columnar, and the first protrusion 21 and the second protrusion 22 extend along the height direction of the liquid separator 23.

[0036] In addition, in order to facilitate the input of gaseous refrigerant into the pump body 12, the first connection hole is located at the bottom of the first protrusion 21; in order to facilitate the input of refrigerant into the second receiving cavity 221, the second connection hole 222 is located at the top of the second protrusion 22.

[0037] Optionally, the liquid separator 23 is cylindrical, and the axial direction of the liquid separator 23 coincides with the axial direction of the compressor 1.

[0038] Furthermore, the outer circumferential surface of the outer casing 11 is cylindrical. In order to reduce the size of the liquid separator while preventing the liquid separator from failing to achieve the pressure stabilization condition, the outer diameter of the outer casing 11 is d1, the outer circumferential surface of the liquid separator 23 is cylindrical, the outer diameter of the liquid separator 23 is d2, d2 is greater than or equal to 1.2d1 and less than or equal to 1.5d1; the axial height of the outer casing 11 is L1, the axial height of the liquid separator 23 is L2, L2 is greater than or equal to 0.5L1 and less than or equal to 1L1.

[0039] Optionally, the diameter of the second connecting hole 222 is greater than or equal to Φ1 and less than or equal to Φ3; the outer peripheral surface of the first protrusion 21 is arc-shaped, and the distance b1 between the tangent point on the inner wall of the first protrusion 21 along the radial direction of the compressor 1 and the outer wall of the housing 11 is greater than the diameter b2 of the second connecting hole 222.

[0040] In this embodiment, the distributor further includes a suction pipe 4 and a refrigerant pipe 5. The suction pipe 4 extends into the second receiving cavity 221 through the second connecting hole 222 and is connected to the second receiving cavity 221. The portion of the suction pipe 4 located in the second receiving cavity 221 is located between the first protrusion 21 and the outer casing 11 to deliver refrigerant to the dispensing chamber 3 through the suction pipe 4. One end of the refrigerant pipe 5 extends into the outer casing 11 through the first connecting hole and is connected to the pump body 12 of the compressor 1. The other end of the refrigerant pipe 5 is connected to the first receiving cavity 211. The portion of the refrigerant pipe 5 located in the first receiving cavity 211 is located between the second protrusion 22 and the outer casing 11 to deliver gaseous refrigerant to the pump body 12 through the refrigerant pipe 5.

[0041] like Figure 2 As shown, further, a refrigerant inlet is provided at the bottom of the housing 11, and the refrigerant inlet is connected to the first connection hole; the refrigerant pipe 5 includes a radial pipe section 51, a transition pipe section 52 and an axial pipe section 53 connected in sequence, the end of the radial pipe section 51 away from the transition pipe section 52 extends into the pump body 12 through the refrigerant inlet; the end of the axial pipe section 53 away from the transition pipe section 52 has a vent 531, so that gaseous refrigerant enters the refrigerant pipe 5 through the vent 531 and enters the pump body 12 through the refrigerant pipe 5; wherein, the center line of the radial pipe section 51 and the center line of the axial pipe section 53 are intersected.

[0042] Optionally, the liquid separator 23 is cylindrical, the centerline of the radial pipe section 51 extends radially along the liquid separator 23, and the centerline of the axial pipe section 53 extends axially along the liquid separator 23; at least part of the wall of the transition pipe section 52 is an arc-shaped pipe section.

[0043] Preferably, the outer diameter of the refrigerant pipe 5 is less than 9 mm; the outer periphery of the second protrusion 22 is arc-shaped, and the distance c1 between the tangent point on the inner wall of the second protrusion 22 along the radial direction of the compressor 1 and the outer casing 11 is greater than the outer diameter c2 of the refrigerant pipe 5; the distance between the vent 531 and the inner wall of the top of the liquid separator 23 is greater than or equal to 15 mm and less than or equal to 20 mm.

[0044] Furthermore, there is a first gap between the axial pipe section 53 and the second connecting opening; there is a second gap between the axial pipe section 53 and the inner wall surface of the second protrusion 22, so as to prevent the axial pipe section 53 from colliding with the second protrusion or the outer casing 11 under vibration during the operation of the dispenser, thereby reducing noise and extending the service life of the dispenser.

[0045] In addition, a plurality of oil return holes 532 are provided on one end of the axial pipe section 53 near the transition pipe section 52. At least some of the oil return holes 532 are spaced apart along the circumference of the axial pipe section 53. The diameter of the oil return holes 532 is less than 0.1 mm, so that the liquid refrigerant after gas-liquid separation in the liquid separation chamber 3 enters the pump body 12 through the oil return holes.

[0046] Specifically, the multiple oil return holes 532 are divided into multiple groups, and each group consists of multiple oil return holes 532 arranged circumferentially along the axial pipe section 53; the multiple groups of oil return holes 532 are arranged axially along the axial pipe section 53.

[0047] Generally, in order to filter impurities in the gaseous refrigerant, such as welding slag and debris, the distributor includes a filter element 6, which is covered on the vent 531.

[0048] Optionally, to increase the filtration area of ​​the filter element 6 and improve the filtration efficiency, the filter element 6 protrudes towards the side away from the refrigerant pipe 5; or the filter element 6 is recessed into the refrigerant pipe 5.

[0049] Furthermore, the outer casing 11 includes a top cover 111, and the liquid separator 23 has a contraction port at one end near the top cover 111. The contraction port is fitted onto the outer casing 11 and connected to it. The opening cross-section of the contraction port gradually decreases along the direction near the top cover 111. Since the liquid separator and the outer casing 11 of the compressor 1 are welded together, the gradually contracting liquid separator 23 in the direction near the top cover 111 presses the liquid separator 23 tightly against the outer casing 11, preventing the liquid separator from shifting relative to the outer casing 11 during use. Moreover, the inner diameter of the contraction port of the gradually contracting liquid separator 23 is the same as the outer diameter of the outer casing 11, which helps to ensure the coaxiality between the liquid separator and the outer casing 11.

[0050] Preferably, the first protrusion 21 and the second protrusion 22 are disposed at both ends along the same diametrical direction of the compressor 1.

[0051] Specifically, the wall thickness of the liquid separator housing 23 is greater than or equal to 3 mm and less than or equal to 5 mm; the displacement of the compressor 1 is a1, and the volume of the liquid separator 3 is a2, a2 ​​is greater than or equal to 30a1 and less than or equal to 40a1, so as to ensure that the pressure regulation of the liquid separator is achieved while reducing the overall size of the compressor, so as not to affect the performance of the liquid separator.

[0052] like Figure 4 As shown, in order to facilitate the installation of the liquid separator on the outer casing 11 of the compressor 1, the liquid separator housing 23 can be arbitrarily divided into multiple sections, and the liquid separator housing 23 sections are connected by welding.

[0053] like Figure 2 As shown, the compressor 1 also includes an oil tank 13 and a lower cover 112. The distance S1 between the bottom of the inner wall of the liquid separator 23 and the lowest point of the lower cover 112 is greater than the distance S2 between the top of the oil tank 13 and the lowest point of the lower cover 112, so as to prevent the high temperature oil in the oil tank 13 from affecting the refrigerant in the liquid separator 3 during the operation of the compressor 1.

[0054] Furthermore, the specific installation structure of the liquid dispenser in this embodiment is as follows:

[0055] One installation structure is as follows: Figures 1 to 3 As shown, the refrigerant inlet is located between the liquid separator 23 and the outer casing 11, and the refrigerant pipe 5 is located in the first receiving cavity 211. This arrangement protects the refrigerant pipe 5, preventing damage caused by partial exposure of the refrigerant pipe 5 to the air during use, and extending the service life of the refrigerant pipe 5.

[0056] Another installation structure is as follows: Figure 5 As shown, the refrigerant inlet is located outside the distributor, and the axial section 53 of the refrigerant pipe 5 is located in the first receiving cavity 211 at one end near the vent 531. This arrangement keeps the refrigerant in the distributor cavity 3 away from the high-temperature oil in the oil tank 13, preventing the high-temperature oil in the oil tank 13 from affecting the refrigerant in the distributor cavity 3 during the operation of the compressor 1.

[0057] A second aspect of the present invention provides a compressor, which includes a housing 11, a liquid distributor and a pump body 12 as described above, wherein the liquid distributor housing 23 is sleeved on the outside of the housing 11; the pump body 12 is disposed inside the housing 11 and communicates with the first receiving cavity 211 of the liquid distributor so that the gaseous refrigerant in the first receiving cavity 211 enters the pump body 12.

[0058] The compressor in this embodiment is a rotary compressor, which also includes a cylinder structure, a crankshaft structure, a roller structure, and a vane structure. The cylinder structure has an inner circumferential structure with a compression chamber communicating with a refrigerant inlet. The refrigerant inlet is located inside the compressor housing 11, where a vane groove is machined. The upper part of the vane groove has a groove bottom hole for cutting the groove and a spring hole for mounting a spring. The crankshaft structure has an eccentric roller in the middle, with its two sides, from top to bottom, referred to as the long shaft and short shaft. The crankshaft structure is driven to rotate by a motor structure. The roller structure, driven by the crankshaft structure, rotates eccentrically within the compression chamber, its outer cylindrical surface tangent to the inner wall of the compression chamber. The vane structure is slidably disposed within the vane groove, with its front end tightly engaged with the roller structure, and its rear end fixedly disposed within the spring hole and pressed against the spring limiting groove by a spring.

[0059] A third aspect of the present invention provides an air conditioner including the compressor 1 described above.

[0060] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0061] This invention provides a liquid separator suitable for a compressor 1. The compressor 1 includes a housing 11, and the liquid separator includes a liquid separator housing 23, a first protrusion 21, and a second protrusion 22. The liquid separator housing 23 is sleeved on the outside of the housing 11, forming a liquid separator chamber 3 between the liquid separator housing 23 and the housing 11. The first protrusion 21 and the second protrusion 22 are spaced apart circumferentially on the liquid separator housing 23, both protruding beyond the outer circumferential surface of the liquid separator housing 23. The first protrusion 21 has a first receiving cavity 211 and a first connecting hole that communicate with each other, and the liquid separator housing 23 has a first connecting opening for connecting the first receiving cavity 211 and the liquid separator chamber 3. The second protrusion 22 has a second receiving cavity 221 and a second connecting hole 222 that communicate with each other, and the liquid separator housing 23 has a second connecting opening for connecting the second receiving cavity 221 and the liquid separator chamber 3. By providing a liquid-liquid separation chamber 3 for gas-liquid separation of the refrigerant entering the liquid-liquid chamber 3; by providing a first connecting hole for transporting the gaseous refrigerant in the first receiving chamber 211 to the pump body 12 of the compressor 1; and by providing a second connecting hole 222 for transporting refrigerant into the second receiving chamber 221, the refrigerant entering the second receiving chamber 221 through the second connecting hole 222 undergoes gas-liquid separation in the liquid-liquid separation chamber 3. The gaseous refrigerant then enters the first receiving chamber 211 and is subsequently transported to the pump body 12 of the compressor 1 through the first connecting hole. This prevents a large amount of liquid refrigerant from entering the pump body 12 and causing pump failure. The body 12 is damaged, and because the first protrusion 21 and the second protrusion 22 are provided, the overall size of the distributor can be reduced. In addition, since the motor of the compressor 1 generates a lot of noise during operation, by setting the annular distributor, a cavity is added between the motor of the compressor 1 and the external environment, thereby reducing the overall noise of the compressor 1 during operation and achieving a noise reduction effect. This solves the problem in the prior art that the setting method of the distributor in the compressor cannot reduce the overall size of the compressor without affecting the use effect of the distributor.
