Description

Technical Field

[0001] The present disclosure relates to the technical field of compressors, and in particular to an oil separator of a compressor, a compressor and an air conditioner. Background Art

[0002] At present, scroll compressors are commonly used in multi-split units. In order to balance the lubricating oil in multiple compressors, an oil equalizing pipe structure is set. When the amount of lubricating oil in the compressor increases and the liquid level exceeds the oil equalizing pipe, the upper end of the oil equalizing pipe is connected to the exhaust pipe, and the flow velocity inside it is high. According to the Bernoulli principle, low pressure is formed, and the excess lubricating oil is sucked out of the compressor. At present, the oil equalizing pipe used in scroll compressors is generally connected to the lower cavity of the motor. The fluid that returns from the trimming forms a vortex at the entrance of the oil equalizing pipe, which is not conducive to the separation of oil and gas. At the same time, the mixed fluid will be directly sucked into the oil equalizing pipe, resulting in the defects of high oil discharge rate and low cooling capacity of the compressor; and part of the fluid directly impacts the liquid surface through the gap of the support ring, causing liquid surface fluctuations.

[0003] Due to the problems in the prior art of multi-connected compressors, the exhaust oil mixture cannot be effectively separated and is sucked out from the oil balancing pipe, resulting in a high oil discharge rate of the compressor; the oil-gas mixture refluxes downward on the inner wall of the compressor and is sucked out from the oil balancing pipe, resulting in a high oil discharge rate of the compressor; when the fluid vortex near the oil balancing pipe in the lower chamber of the motor is stirred, the fluid with oil is directly discharged from the oil balancing pipe interface, resulting in a high oil discharge rate of the compressor; part of the fluid directly impacts the liquid surface through the gap between the support rings, causing liquid surface fluctuations and other technical problems. Therefore, the present invention studies and designs an oil separator, a compressor and an air conditioner for a compressor.

[0039] like Figure 1-4As shown, the present disclosure provides an oil separator for a compressor, which comprises:

[0040] The compressor comprises a housing 1, the oil distributor 100 is arranged inside the housing 1, the housing 1 is provided with an oil equalizing hole 2, and the oil equalizing hole 2 can guide the oil inside the housing 1; the housing of the compressor is connected with an oil equalizing pipe, and the oil equalizing pipe is located outside the housing and can be connected with the oil equalizing hole of the housing;

[0041] The oil separator 100 is arranged at the position of the oil balancing hole 2 and can cover the oil balancing hole 2. The oil separator 100 can absorb the oil-gas mixture flowing down from the top thereof, and perform oil and gas separation in the oil separator 100. The separated oil can reach the bottom oil pool of the compressor, and the separated gas can return to the shell 1.

[0042] The present invention provides an oil separator structure at the oil equalizing hole position inside the compressor housing, which can receive the oil-gas mixture from above and below and separate the oil and gas, discharge the separated oil into the bottom oil pool, and return the separated gas to the housing 1. The newly added oil separator structure is fixedly connected to the housing on the basis of the original oil equalizing pipe interface, and the oil equalizing pipe interface is separated from the fluid returning from the upper side. At the same time, the oil-gas mixture is separated by diversion, which can effectively avoid or reduce the situation where the oil-gas mixture is discharged outward from the oil equalizing hole; first, the oil separator structure is used to separate the oil and gas flowing downward from the stator cut edge. The mixture can be separated to reduce the mixing degree in the lower chamber, thereby reducing the oil discharge rate of the compressor; secondly, it can effectively isolate the influence of wall reflux, prevent the fluid after the wall return oil flows down from being directly sucked away by the oil balancing pipe, and reduce the oil discharge rate of the compressor; thirdly, it can reduce the situation where the fluid is directly discharged from the interface with oil when the fluid vortex near the oil balancing pipe in the lower chamber of the motor is stirred, and further reduce the oil discharge rate of the compressor; the present invention can reduce the impact of the exhaust gas on the oil pool surface through the gap of the support ring 11 by discharging the separated gas in the horizontal direction rather than the vertical direction, thereby reducing the fluctuation of the oil pool.

[0043] In some embodiments, the oil separator 100 includes a first part 3 and a second part 4, the first part 3 and the second part 4 are joined to define a separation chamber 5 therebetween, and the oil separator 100 also includes a third part 6, the third part 6 is located at the bottom of the separation chamber 5, the separation chamber 5 can inhale the oil-gas mixture flowing down from above, and the third part 6 can receive the impact of the oil-gas mixture from the separation chamber 5 to produce oil-gas separation. This is the preferred structural form of the oil separator disclosed in the present invention, the separation chamber can be formed by the first part and the second part, and the third part can impact the oil-gas mixture from top to bottom, thereby completing the oil-gas separation.

[0044] In some embodiments, a first channel 7 allowing the separated oil to flow can be defined between the third portion 6 and the first portion 3, and a second channel 8 and / or a third channel 9 allowing the separated gas to flow can also be defined between the third portion 6 and the first portion 3. The present disclosure can guide the separated oil to the oil pool at the bottom of the compressor housing by setting the first channel, and can guide the separated refrigerant gas to the inside of the compressor housing through the second channel and the third channel, thereby effectively avoiding the situation where the oil-gas mixture is directly discharged from the outside of the housing through the oil equalization hole position, resulting in excessive oil discharge from the compressor.

[0045] In some embodiments, the third portion 6 includes a first partition plate 61, a second partition portion 62 and a third partition plate 63, the second partition portion 62 is located between the first partition plate 61 and the third partition plate 63, and the first partition plate 61, the second partition portion 62, the third partition plate 63 and the first portion 3 jointly define the first channel 7;

[0046] When a second channel 8 is included, the first partition plate 61 and the first portion 3 jointly define the second channel 8 , and / or when a third channel 9 is included, the third partition plate 63 and the first portion 3 jointly define the third channel 9 .

[0047] This is the preferred structural form of the third part of the present invention. The first partition plate, the second partition plate and the third partition plate can define a first channel allowing oil to pass through the first part in the direction opposite to the oil equalizing hole, so that the oil is discharged from the first channel in the front and downward into the oil pool at the bottom. The first partition plate can define a second channel and a third channel in the side direction with the first part, so that the gas is discharged from the exhaust port of the side plate.

[0048] In some embodiments, the height of the upper end surface of the first partition plate 61 is higher than the height of the upper end surface of the second partition portion 62, and / or the height of the upper end surface of the third partition plate 63 is higher than the height of the upper end surface of the second partition portion 62. The upper end surface heights of the first partition plate and the third partition plate are both higher than the upper end surface height of the second partition portion, which can block the oil that impacts the upper end surface of the second partition portion and prevent the oil from being discharged from the gas channel of the side plate. Since the gas is lighter in density than the oil, it is above the oil and is discharged from the side directions of the first partition plate and the third partition plate, respectively, thereby effectively achieving the effect of oil and gas separation and separate extraction. The oil is guided to the bottom oil pool to ensure a sufficient amount of lubricating oil inside the compressor housing, while the gas is guided back into the housing to prevent the refrigerant from leaking out of the housing.

[0049] In some embodiments, the first end face 611 of the first partition plate 61 facing the first part 3 is arranged closer to the first part 3 than the second end face 621 of the second partition 62 facing the first part 3, and the third end face 631 of the third partition plate 63 facing the first part 3 is arranged closer to the first part 3 than the second end face 621 of the second partition 62 facing the first part; the first channel 7 includes a first groove structure defined by the first end face 611, the second end face 621 and the third end face 631. The present disclosure defines a first groove structure between the three end faces and between the first parts by having the first end face of the first partition plate be longer than the second end face of the second partition, and the third end face of the third partition plate be longer than the second end face of the second partition, so as to form a first channel allowing oil to pass through, and both the first end face and the third end face can play a role in sealing oil and gas.

[0050] In some embodiments, the second part 4 includes a base plate 41 and a guide part 42, the base plate 41 is fixedly connected to the housing 1, the lower end of the base plate 41 is connected to the third part 6, the guide part 42 is connected to the base plate 41, and the guide part 42 is located above the third part 6, and the guide part 42 can guide the airflow from top to bottom to the third part 6. The present disclosure also enables the oil separator to be fixed to the position of the oil equalizing hole of the housing through the base plate of the second part, the first part is fixedly connected to the second part, and the third part is fixed to the inner wall of the housing through the second part; the guide part can effectively guide the oil-gas mixture above to the third part for oil-gas separation.

[0051] In some embodiments, the second portion 4 further includes a filter component 43, which is connected to the base plate 41 and is located above the air guide 42, and can filter the airflow above the air guide 42. The filter component of the present disclosure can filter the oil-gas mixture before entering the air guide, remove impurities, and prevent the impurities from reaching the bottom oil pool through the oil separator.

[0052] In some embodiments, the guide portion 42 includes a first guide plate 421 and a second guide plate 422, a first opening 45 is provided between the upper end of the first guide plate 421 and the upper end of the second guide plate 422, a second opening 46 is provided between the lower end of the first guide plate 421 and the lower end of the second guide plate 422, and the width of the first opening 45 is greater than the width of the second opening 46. This is a preferred structural form of the guide portion of the present disclosure, that is, the oil-gas mixture can be guided by the first and second guide plates and the opening formed therebetween, and the space between the openings is a space for the oil-gas mixture to flow.

[0053] It is further preferred that a guide channel is defined between the first guide plate and the second guide plate, and the width of the guide channel gradually decreases from top to bottom.

[0054] In some embodiments, when the second part 4 further includes a filtering component 43:

[0055] One end of the filter component 43 is connected to the upper end of the first guide plate 421, and the other end is connected to the upper end of the second guide plate 422; and / or, the filter component 43 is a filter structure. The filter component of the present disclosure is connected and arranged between the upper ends of the first and second guide plates, and can fully filter the oil-gas mixture flowing into the space between the two guide plates.

[0056] In some embodiments, the filter component 43 is an upwardly protruding arched structure; and / or the projection surface of the first guide plate 421 on the substrate 41 is an arcuate plate structure, and the projection surface of the second guide plate 422 on the substrate 41 is an arcuate plate structure. The filter component is configured as an upwardly protruding arched structure to increase the filtering area, and the first and second guide plates of the arcuate plate structure can guide the airflow along the arcuate surface, thereby improving the guiding effect.

[0057] In some embodiments, the first part 3 includes a second groove structure 31, and the second groove structure 31 can accommodate the third part 6 therein. Preferably, the first part 3 has a streamlined shape, which can reduce the resistance of the airflow. The second groove structure of the first part of the present disclosure can be engaged with the second part and the third part, and the third part can be effectively accommodated therein.

[0058] In some embodiments, the lower end of the second groove structure 31 is a discharge port 311 for oil discharge, the lower end of the first part 3 opposite to the first partition plate 61 is formed as a first exhaust port 32, the second channel 8 is connected to the first exhaust port 32 to discharge gas, and the first exhaust port 32 is oriented in a non-vertical direction; the lower end of the first part 3 opposite to the third partition plate 63 is formed as a second exhaust port (not shown), the third channel 9 is connected to the second exhaust port (not shown) to discharge gas, and the second exhaust port (not shown) is oriented in a non-vertical direction. The present disclosure enables the oil to be discharged downward along the second groove through the first exhaust port through the discharge port at the lower end of the second groove structure, and the separated gas can be blown out in the lateral direction through the second channel and the third channel respectively through the first exhaust port set on the side of the first part and the second exhaust port set on the other side, rather than the vertical direction. Such a setting can effectively avoid the impact of the exhaust gas on the oil pool liquid surface through the gap of the support ring, and reduce the fluctuation of the oil pool.

[0059] In some embodiments, when the second part 4 includes a guide part 42: the second groove structure 31 includes a first section and a second section distributed from top to bottom in the vertical direction, the first section accommodates the guide part 42 therein, the second section accommodates the third part 6 therein, and the volume of the first section is smaller than the volume of the second section. This is the preferred structural form of the second groove structure disclosed in the present invention, that is, the volume of the second section located below is larger than the volume of the first section located above, because the second section is used to accommodate the third part, the first section is used to accommodate the guide part and the filter component, the volume of the third part is larger than the guide part, etc., so such a setting can ensure effective accommodation of the third part and the guide part.

[0060] In some embodiments, the third part 6 further includes a first transverse plate 64, one end of which is connected to the first partition plate 61, and the other end of which extends in a non-vertical direction to guide the airflow toward the first exhaust port 32; the third part 6 further includes a second transverse plate 65, one end of which is connected to the third partition plate 63, and the other end of which extends in a non-vertical direction to guide the airflow toward the second exhaust port (not shown). The airflows blown out of the second channel and the third channel can be guided in the lateral direction by the first transverse plate and the second transverse plate, respectively, so that the gas is blown out in the side direction, effectively avoiding the impact of the exhaust gas on the oil pool liquid surface through the support ring gap, and reducing the fluctuation of the oil pool.

[0061] In some embodiments, the second partition 62 includes a cavity 622 facing the housing 1 , and the cavity 622 can be communicated with the oil balancing hole 2 ;

[0062] A first balancing hole 612 is provided on the first partition plate 61, one end of the first balancing hole 612 can be connected to the cavity 622, and the other end can be connected to the outside of the first partition plate 61, so that the oil inside the shell 1 can be introduced into the cavity 622 through the first balancing hole 612 and discharged through the oil balancing hole 2; and / or, a second balancing hole (not shown) is provided on the third partition plate 63, one end of the second balancing hole (not shown) can be connected to the cavity 622, and the other end can be connected to the outside of the third partition plate 63, so that the oil inside the shell 1 can be introduced into the cavity 622 through the first balancing hole 612 and discharged through the oil balancing hole 2.

[0063] The present invention can connect the oil balancing holes through the arrangement of the cavity of the second partition, and the arrangement of the first balancing hole can enable the oil pool at the bottom of the compressor casing to be connected through the first and second balancing holes when the liquid level of the oil pool rises to the position of the first balancing hole and the second balancing hole, and then be discharged to the outside of the casing through the oil balancing holes. That is, when the amount of oil inside the compressor casing is sufficient, it is discharged outward through the oil balancing holes, and if the amount of oil is insufficient, the oil level is lower than the first balancing hole, so the oil in the casing will not be discharged from the oil balancing holes. The scheme of the present invention can effectively prevent the oil-gas mixture flowing from top to bottom from being discharged through the oil balancing holes, thereby effectively reducing the oil discharge amount of the compressor.

[0064] In some embodiments, the height of the first balancing hole 612 is equal to the height of the oil balancing hole 2, and the height of the second balancing hole (not shown) is equal to the height of the oil balancing hole 2. Such a design can ensure that the oil entering the cavity through the first and second balancing holes can be smoothly discharged through the oil balancing holes, thereby preventing excessive oil in the oil pool.

[0065] The present disclosure further provides a compressor, which includes the oil separator of the compressor as described in any of the preceding items, and also includes the shell 1 , the shell is provided with the oil balancing hole 2 , and the oil separator is arranged at the position of the oil balancing hole 2 .

[0066] In some embodiments, an oil balancing pipe 10 is further included. The oil balancing pipe 10 is located outside the housing 1 , and one end of the oil balancing pipe 10 is connected to the oil balancing hole 2 .

[0067] The present invention provides an oil separator structure for reducing the oil discharge rate of a scroll compressor and a compressor having the same. The oil separator structure is as follows: Figure 1 As shown, it is composed of an outer plate (i.e., the first part), a filter screen, and an inner plate (the second part 4), and a guide plate, an oil collecting platform, and a partition plate (the oil collecting platform and the partition plate constitute the third part 6) are arranged on the base plate, and the oil separator assembly is divided into different chambers and flow channels;

[0068] The guide plate, the oil collecting platform (third partition), the first and third partition plates are fixedly arranged on the base plate;

[0069] A filter screen is installed in the structure, which is an upward arched structure;

[0070] The guide plate is bent inwardly to guide the fluid to the center;

[0071] The oil collecting platform is in an arc shape, and is lowest near the center;

[0072] The partition plate divides the lower chamber into four parts, with the two sides being air flow channels (the second channel 8 and the third channel 9), the middle front part being the oil return channel (the first channel 7), and the rear part being the oil equalizing pipe inlet chamber (i.e., the cavity 622);

[0073] The upper edges of the partition plates on both sides are 2-3 mm higher than the oil collecting platform to prevent the collected lubricating oil from flowing down through the air flow channels on both sides and mixing again;

[0074] The left and right sides of the partition plate are provided with balancing holes, which penetrate the oil balancing pipe inlet cavity, and the height of the lower edge thereof is consistent with the height of the lower edge of the oil balancing pipe, so as to ensure that the oil balancing height of the oil balancing pipe is consistent;

[0075] The flow area of ​​the balancing hole is the same as the diameter of the oil balancing pipe;

[0076] The lower end of the partition plate is provided with first and second transverse plates, which can guide the fluid to a transverse discharge;

[0077] The lower end of the outer plate is provided with a first exhaust port 32 and a second exhaust port, which cooperate with the first and third partition plates to guide the separated gas out;

[0078] The diameter of the arc surface of the oil separator base plate and the outer plate mounting portion is the same as the diameter of the shell, which is convenient for fixed connection.

[0079] The oil separator separates the oil equalizing pipe interface from the fluid returning from the upper side. During the operation of the compressor, the fluid returning from the motor trim is separated by the turbulence of the filter and the guide plate, and the oil is collected on the oil collecting table and then returned through the oil return channel. The gas is discharged laterally through the air flow channels on both sides. In order to ensure that the oil equalizing function of the oil equalizing pipe is not affected, balance holes are opened at the air flow channels on both sides of the oil separator. The newly added oil separator structure can bring the following advantages: First, the oil-gas mixture flowing downward from the stator trim is separated by the oil separation structure, reducing the mixing degree of the lower cavity, thereby reducing the oil discharge rate of the compressor; second, the influence of the wall return flow is isolated to prevent the fluid after the wall return oil from flowing down from being directly sucked away by the oil equalizing pipe, thereby reducing the oil discharge rate of the compressor; third, the fluid carrying oil is directly discharged from the interface when the fluid vortex is stirred near the oil equalizing pipe in the lower cavity of the motor, further reducing the oil discharge rate of the compressor; fourth, the air flow is discharged laterally, which reduces the impact of the exhaust gas on the oil pool liquid surface through the gap of the support ring 11 and reduces the fluctuation of the oil pool.
