Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and in particular to an exhaust component and a compressor. Background Art

[0002] Scroll compressors are widely used in systems such as air conditioners and heat pumps due to their high efficiency, compact size, and smooth operation. Traditional scroll compressors utilize an oil supply mechanism to lubricate the pump end faces by supplying refrigerant oil from the oil sump at the bottom of the compressor via the crankshaft. This results in a significant amount of oil being mixed with the refrigerant gas discharged from the stator during operation. This causes the oil inside the compressor to be carried away by the refrigerant gas and discharged outside the compressor, increasing the compressor's oil discharge rate, reducing compressor performance, and easily leading to oil starvation and wear on the pump end faces.

[0003] Since the oil inside the compressor in the prior art is easily carried away by the refrigerant gas and discharged to the outside of the compressor when the compressor is working, the oil discharge rate of the compressor increases, the performance of the compressor decreases, and it is easy to cause problems such as oil shortage and wear of the pump body. Therefore, the present invention studies and designs an exhaust component and a compressor. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that when the compressor is working, the oil inside the compressor is easily carried away by the refrigerant gas and discharged to the outside of the compressor, resulting in an increased oil discharge rate of the compressor, thereby providing an exhaust component and a compressor.

[0005] In order to solve the above problems, the present invention provides an exhaust assembly, which includes:

[0006] An exhaust slider and an exhaust stator, the exhaust slider is sleeved on the exhaust stator and can move on the exhaust stator along the center line direction of the exhaust stator. The exhaust stator is provided with an inlet, and a cavity is formed in the exhaust slider. The inlet is connected to the cavity so that an oil-gas mixture can enter the cavity through the inlet and perform oil-gas separation in the cavity. The exhaust slider has a first position for sealing the cavity and a second position for communicating with the outside. In the center line direction of the exhaust stator, a first gap is formed between the inner side wall of the exhaust slider on one side of the cavity and the outer side wall of the exhaust stator, and a second gap is formed between the inner side wall of the exhaust slider on the other side and the outer side wall of the exhaust stator. After the oil-gas mixture enters the cavity and performs oil-gas separation, the liquid can be discharged through the first gap and the gas can be discharged through the second gap.

[0007] In some embodiments, a limit plate is provided on the exhaust stator, and the limit plate is located on the exhaust stator near the second position relative to the first position. In the centerline direction of the exhaust stator, the first position, the second position and the limit plate are arranged in sequence. When the exhaust slider is located at the second position, the limit plate can limit the exhaust slider.

[0008] In some embodiments, a limiting column is provided on the end face of the limiting plate facing the second position. When the exhaust slider is located at the second position, the limiting column can be connected with the exhaust slider so that the limiting plate and the exhaust slider form a channel. After the gas flows out from the second gap, it is discharged through the channel.

[0009] In some embodiments, a third groove is provided on the end face of the exhaust slider facing the limit plate, and the third groove connects the inner wall of the exhaust slider and the outer wall of the exhaust slider. When the exhaust slider is located at the second position, the limit plate is connected to the exhaust slider so that the inner wall of the third groove and the limit plate form a channel, and the gas flows out from the second gap and is discharged through the channel.

[0010] In some embodiments, a fourth groove is provided on the inner sidewall of the exhaust slider along the circumference of the exhaust slider.

[0045] See also Figures 1 to 26 As shown, according to an embodiment of the present invention, an exhaust assembly is provided, comprising: an exhaust slider 1 and an exhaust stator 2, wherein the exhaust slider 1 is sleeved on the exhaust stator 2 and can move on the exhaust stator 2 along the centerline direction of the exhaust stator 2. The exhaust stator 2 is provided with an inlet, and a cavity 5 is formed therein. The inlet is connected to the cavity 5 so that an oil-gas mixture can enter the cavity 5 through the inlet and perform oil-gas separation in the cavity 5. The exhaust slider 1 has a first position for sealing the cavity 5 and a second position for communicating the cavity 5 with the outside. In the centerline direction of the exhaust stator 2, a first gap 6 is formed between the inner sidewall of the exhaust slider 1 on one side of the cavity 5 and the outer sidewall of the exhaust stator 2, and a second gap 7 is formed between the inner sidewall of the exhaust slider 1 on the other side and the outer sidewall of the exhaust stator 2. After the oil-gas mixture enters the cavity 5 and is separated, liquid can be discharged through the first gap 6 and gas can be discharged through the second gap 7. In this technical solution, the exhaust stator 2 is provided with an inlet, and the exhaust slider 1 has a cavity 5. When installing, the exhaust stator 2 is installed on the fixed scroll plate 13, and the inlet is connected to the exhaust port of the fixed scroll plate 13, and the inlet is always connected to the cavity 5. Figures 13 to 16As shown, when the compressor is running, the oil-gas mixture can enter the cavity 5 through the inlet and collide with the inner wall of the cavity 5, so that the oil-gas mixture generates turbulence in the cavity 5, so that the oil and gas are separated. The exhaust slider 1 can move on the exhaust stator 2. The exhaust slider 1 has a first position that seals the cavity 5. When the exhaust slider 1 is in the first position, the inner wall of the exhaust slider 1 is completely in contact with the outer wall of the exhaust stator 2 to seal the cavity 5. The exhaust slider 1 also has a second position that connects the cavity 5 to the outside. In the centerline direction of the exhaust stator 2, the inner side wall of the exhaust slider 1 on one side of the cavity 5 is in contact with the outer wall of the exhaust stator 2. A first gap 6 is formed between the outer walls, and a second gap 7 is formed between the inner wall of the exhaust slider 1 on the other side and the outer wall of the exhaust stator 2. Due to the push of the gas in the cavity 5, the exhaust slider 1 moves from the first position to the second position. The liquid after oil and gas separation is discharged through the first gap 6 under the action of gravity, and the gas is discharged through the second gap 7. This solves the problem of poor oil separation effect in the cavity of the existing compressor, reduces the oil discharge rate, improves performance and reliability, and has a simple structure and is easy to process. When the compressor finishes running, the fixed scroll 13 stops exhausting, and the exhaust slider 1 falls back to the first position along the exhaust stator 2. The cavity 5 is in a sealed state, thereby achieving the purpose of exhaust anti-reversal. Figure 1 As shown, the scroll compressor includes a crankshaft 3, a fixed scroll 13, an air intake pipe 14, a casing 15, a movable scroll 16, and an upper bracket 17, and its structure is the same as that of an existing scroll compressor.

[0046] In some embodiments, see Figures 2 to 12 As shown, the exhaust stator 2 is provided with a limit plate 4. The limit plate 4 is located on the exhaust stator 2 at a position closer to the second position relative to the first position. In the centerline direction of the exhaust stator 2, the first position, the second position, and the limit plate 4 are arranged in sequence. When the exhaust slider 1 is in the second position, the limit plate 4 can limit the exhaust slider 1. In this technical solution, the limit plate 4 is located on the exhaust stator 2 at a position closer to the second position relative to the first position. When the exhaust slider 1 is in the second position, the exhaust slider 1 is limited by the limit plate 4. When the pressure in the cavity 5 is too high, the exhaust slider 1 is prevented from separating from the exhaust stator 2 during movement, ensuring the stable operation of the exhaust assembly of the present invention. The limit plate 4 and the exhaust stator 2 can be connected by welding or other connection methods. In the present invention, the limit plate 4 and the exhaust stator 2 are connected by a threaded connection. The limit plate 4 or the exhaust stator 2 is provided with a stud. Conversely, the exhaust stator 2 or the limit plate 4 is provided with a screw hole, thereby connecting the limit plate 4 to the exhaust stator 2.

[0047] In some embodiments, see Figures 20 to 22As shown, a limiting post 8 is provided on the end surface of the limiting plate 4 facing the second position. When the exhaust slider 1 is in the second position, the limiting post 8 can connect with the exhaust slider 1, so that the limiting plate 4 and the exhaust slider 1 form a channel. After the gas flows out of the second gap 7, it is discharged through the channel. In this technical solution, the limiting post 8 is provided on the end surface of the limiting plate 4 facing the second position. The limiting post 8 not only limits the exhaust slider 1, preventing the exhaust slider 1 from separating from the exhaust stator 2 during movement when the pressure in the cavity 5 is too high, but also forms a channel between the limiting plate 4 and the exhaust slider 1. After the oil and gas mixture separates in the cavity 5, the gas flows out of the second gap 7 and is discharged through the channel. There are multiple limiting posts 8. When the limiting plate 4 is circular, the multiple limiting posts 8 are evenly arranged along the circumference of the limiting plate 4 to ensure uniform force on the exhaust slider 1 and the exhaust volume of the exhaust channel. A limiting column 8 is provided on the limiting plate 4, and the limiting plate 4 is installed on the exhaust stator 2. When the exhaust slider 1 moves up to the limiting column 8, a gap exists between the exhaust slider 1 and the limiting column 8, so that the exhausted refrigerant gas can be discharged from the gap.

[0048] In some embodiments, a third groove 18 is provided on the end surface of the exhaust slider 1 facing the stop plate 4. The third groove 18 connects the inner and outer walls of the exhaust slider 1. When the exhaust slider 1 is in the second position, the stop plate 4 abuts the exhaust slider 1, forming a channel between the inner wall of the third groove 18 and the stop plate 4. Gas flows out of the second gap 7 and is then discharged through the channel. In this technical solution, the third groove 18 connects the inner and outer walls of the exhaust slider 1. When the exhaust slider 1 is in the second position, the stop plate 4 abuts the exhaust slider 1, forming a channel between the third groove 18 and the stop plate 4. After the oil and gas mixture separates within the cavity 5, the gas flows out of the second gap 7 and is then discharged through the channel. Multiple third grooves 18 are provided. When the end surface of the exhaust slider 1 facing the stop plate 4 is circular, the multiple third grooves 18 are evenly spaced along the circumference of the stop plate 4 to ensure the exhaust volume of the exhaust channel. A groove is added to the top of the exhaust slider 1. At this time, there is no need to set a limit column 8 on the limit plate 4. When the exhaust slider 1 moves along the exhaust stator 2 to the limit plate 4, there is a gap between the groove on the top of the exhaust slider 1 and the limit plate 4, so that the exhausted refrigerant gas can be discharged from the gap, thereby achieving the purpose of oil and gas separation.

[0049] In some embodiments, a fourth groove is provided on the inner sidewall of the exhaust slider 1 along its circumference. When the exhaust slider 1 is in the first position, the inner wall of the fourth groove and the outer wall of the exhaust stator 2 enclose a cavity 5. In this technical solution, the cavity 5 is formed by the inner wall of the fourth groove and the outer wall of the exhaust stator 2. After entering the cavity 5, the oil-gas mixture collides with the inner wall of the cavity 5, thereby generating turbulent flow within the cavity 5 and separating the oil and gas. When the exhaust slider 1 is a rotating body, the fourth groove is an annular groove, maximizing the communication area between the cavity 5 and the second gap 7 and the first gap 6, ensuring that the separated gas and liquid can be quickly discharged through the second gap 7 and the first gap 6. Furthermore, the cavity 5 can also be completely located within the exhaust slider 1, with a connecting hole and multiple discharge grooves formed on the inner wall of the exhaust slider 1. The connecting hole connects to the inlet, and the gas and liquid are discharged through the discharge grooves.

[0050] In some embodiments, the exhaust stator 2 has a truncated cone structure, the inner side wall of the exhaust slider 1 matches the outer peripheral wall of the exhaust stator 2, and with the longitudinal section of the exhaust stator 2 as the projection surface, the angle between the end face of the exhaust stator 2 where the inlet is opened and the outer peripheral wall of the exhaust stator 2 is θ, and 20°<θ<90°. In this technical solution, the exhaust stator 2 has a truncated cone structure, the inner side wall of the exhaust slider 1 matches the outer peripheral wall of the exhaust stator 2, and the height of the exhaust stator 2 is greater than the height of the exhaust slider 1. Since the mating surface between the exhaust stator 2 and the exhaust slider 1 is truncated cone-shaped, or can be conical, when the exhaust slider 1 moves upward, a gap is generated between the exhaust stator 2 and the exhaust slider 1. As the slider moves upward, the gap gradually expands, thereby discharging the separated gas and liquid through the gap. See Figures 23 to 26As shown, when the compressor is at rest, the exhaust slider 1 is located at the bottom of the exhaust stator 2. The exhaust slider 1 and the exhaust stator 2 form a sealed cavity 5. When the compressor is running, the high-pressure oil-gas mixture generated by the pump body enters the inlet of the exhaust stator 2 through the exhaust port and is then discharged into the cavity 5 through the inlet. The discharged high-pressure mixture exerts an upward force on the exhaust slider 1, causing it to slide upward along the exhaust stator 2. Because the mating surface between the exhaust stator 2 and the exhaust slider 1 is tapered, when the exhaust slider 1 moves upward, a gap is generated between the exhaust stator 2 and the exhaust slider 1. As the exhaust slider 1 moves upward, the gap gradually expands. The oil-gas mixture discharged from the pump body generates turbulence in the cavity 5, which separates the oil and gas. The heavier oil droplets flow down from the first gap 6, enter the second groove 11 on the stator plate, and flow into the end surface of the stator plate through the second hole 12 to lubricate the pump body. The gas flows through the second gap 7 to the gap formed between the exhaust slider 1 and the limit column 8, and then flows out of the gap, thereby achieving the purpose of oil and gas separation. When the compressor stops running, the pump body stops exhausting, and the exhaust slider 1 falls back along the stator to the stator plate. The exhaust stator 2 and the exhaust slider 1 are in a sealed state, thereby achieving the purpose of exhaust anti-reversal. The exhaust stator 2 of the present invention is a conical structure, wherein 20°<θ<90°, the exhaust stator 2 is provided with a vertical hole at the bottom, and an inclined hole is provided on the outside, and the inclined hole is connected to the vertical hole; the exhaust stator 2 is installed on the stator plate. The exhaust slider 1 is provided with a conical through hole and a cylindrical groove inside, and its conical through hole is connected to the cylindrical hole; the exhaust slider 1 is installed on the exhaust stator 2 and can slide up and down along the exhaust stator 2.

[0051] In some embodiments, see Figures 18 to 20As shown, the exhaust component also includes a fixed vortex plate 13, which has an exhaust port. The exhaust stator 2 is arranged on the fixed vortex plate 13, and the inlet includes a first groove 10 and a first hole 9. The first groove 10 is connected to the exhaust port. One end of the first hole 9 is connected to the first groove 10, and the other end is connected to the cavity 5. In this technical solution, the exhaust component also includes a fixed vortex plate 13, and the inlet includes a first groove 10 and a first hole 9. The oil-gas mixture discharged from the fixed vortex plate 13 is transported to the cavity 5 through the first groove 10 and the first hole 9, so as to perform oil-gas separation. Preferably, a plurality of first holes 9 are provided along the circumference of the exhaust stator 2, and one end of the first hole 9 is connected to the first groove 10, and the other end is opened on the outer peripheral wall of the exhaust stator 2 to ensure communication with the cavity 5. The exhaust stator 2 is mounted on the fixed scroll 13 so that the first groove 10 is in communication with the exhaust port of the fixed scroll 13. Preferably, during installation, the opening of the first groove 10 completely covers the exhaust port. The surface of the first groove 10 of the exhaust stator 2 is sealed against the fixed scroll 13, allowing the oil-air mixture discharged from the exhaust port to completely enter the first groove 10 and then enter the cavity 5 through the first hole 9. The first groove 10 is vertical, and the first hole 9 is an inclined hole that is in communication with the first groove 10. The exhaust stator is mounted on the fixed scroll.

[0052] In some embodiments, the fixed scroll 13 is provided with a second groove 11, which is opposite to the first gap 6. After the liquid is discharged from the first gap 6, it can flow into the second groove 11 for convergence. In this technical solution, the fixed scroll 13 is provided with a second groove 11, which is opposite to the first gap 6. The second groove 11 acts as a confluence groove to collect the separated liquid, which eventually flows back into the compressor cavity and continues to lubricate various components as lubricant, thereby improving the utilization rate of the liquid.

[0053] In some embodiments, the fixed scroll 13 is provided with a second hole 12. The second hole 12 penetrates the fixed scroll 13 along the axial direction of the fixed scroll 13 and communicates with the second groove 11. The liquid in the second groove 11 can flow into the pump body of the compressor through the second hole 12. In this technical solution, the liquid converging in the second groove 11 is returned to the pump body of the compressor or the compressor oil sump through the second hole 12, thereby being reused, improving the utilization rate of the lubricating oil, and enhancing the performance of the compressor.

[0054] The present invention also provides a compressor including the aforementioned exhaust assembly. The scroll compressor of the present invention can solve the problem of poor oil separation within the cavity of existing compressors, reduce oil discharge rate, and improve performance and reliability. The scroll compressor of the present invention has a simple oil separation structure and is easy to manufacture. It also has an exhaust anti-reverse function, which can reduce suction resistance.

The above description is merely a preferred embodiment of the present invention.
