Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular to a compressor and an air conditioner having the same. Background Art

[0002] In the prior art, the refrigerant discharged from the pump body assembly of the air conditioner compressor carries a large amount of oil and enters the exhaust chamber above the motor through the air flow channels of the stator assembly and the rotor assembly of the motor, wherein the oil and gas mixture passing through the rotor assembly of the motor is separated from the oil and gas under the action of the rotating centrifugal force of the rotor assembly and the oil baffle, and the separated oil is thrown onto the cavity wall of the exhaust chamber of the compressor, and flows back to the exhaust chamber or the oil pool below the motor along the gap between the outer peripheral surface of the stator assembly and the cavity wall of the exhaust chamber.

[0003] However, some refrigerant carrying a large amount of oil will rise into the exhaust chamber above the motor through the gap between the outer circumference of the stator assembly and the wall of the exhaust chamber. In this process, the resistance to the return of the oil in the gap between the outer circumference of the stator assembly and the wall of the exhaust chamber is increased, making it difficult for the oil separated in the exhaust chamber above the motor to flow back into the exhaust chamber or the oil pool below the motor, resulting in a high oil discharge rate of the compressor. A high oil discharge rate can easily lead to a drop in the oil level in the oil pool, and insufficient oil supply to the pump body leads to increased power consumption of the friction pair.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In order to solve the problem of high oil discharge rate of the compressor of the air conditioner in the prior art, the present invention provides a compressor and an air conditioner. The air conditioner includes a compressor, and the compressor is the compressor described above and below.

[0038] like Figure 1 and Figure 2 As shown, the compressor includes a shell 10, a motor 20, a pump body assembly 30 and a diverter 40, the shell 10 has an exhaust chamber 11; the motor 20 is arranged in the exhaust chamber 11, and the motor 20 has a first flow passage 211; the pump body assembly 30 is arranged in the exhaust chamber 11 and is located below the motor 20, and the pump body assembly 30 has an exhaust port; the diverter 40 is arranged in the exhaust chamber 11 and is located between the motor 20 and the pump body assembly 30, the diverter 40 has a second flow passage 411, and the first flow passage 211 and the exhaust port are both connected to the second flow passage 411; wherein, after the refrigerant discharged from the exhaust port enters the exhaust chamber 11 through the second flow passage 411 and the first flow passage 211 for oil-gas separation, the oil flows back to the oil pool through the gap formed between the outer peripheral surface of the motor 20 and the inner wall surface of the shell 10.

[0039] The present application provides a compressor with a diverter 40, which ensures that the exhaust and oil return of the compressor pump assembly 30 can operate independently, and is also beneficial to reducing the oil discharge rate of the compressor.

[0040] Specifically, by arranging the diversion part 40 between the motor 20 and the pump body assembly 30, and the first flow channel 211 of the motor 20 and the exhaust port of the pump body assembly 30 are both connected to the second flow channel 411 of the diversion part 40, the refrigerant carrying oil discharged from the exhaust port enters the exhaust chamber 11 above the motor 20 through the second flow channel 411 and the first flow channel 211 for oil-gas separation, and the separated oil flows back to the exhaust chamber 11 or the oil pool below the motor 20 through the gap between the outer peripheral surface of the motor 20 and the cavity wall of the exhaust chamber 11, thereby preventing the refrigerant carrying oil discharged from the exhaust port from entering the exhaust chamber 11 above the motor 20 upward from the gap between the outer peripheral surface of the motor 20 and the cavity wall of the exhaust chamber 11, thereby greatly reducing the reflux resistance of the separated oil from the gap between the outer peripheral surface of the motor 20 and the cavity wall of the exhaust chamber 11 into the exhaust chamber 11 below the motor 20 or the oil pool, which is beneficial to reducing the oil discharge rate of the compressor and further ensuring the working reliability of the compressor.

[0041] like Figures 1 to 7 As shown, the flow divider 40 includes an annular housing 41 having a second flow passage 411 ; the motor 20 includes a stator assembly 22 and a rotor assembly 21 , the stator assembly 22 is located on the outer peripheral side of the rotor assembly 21 , and the rotor assembly 21 has a first flow passage 211 .

[0042] It should be noted that in the present application, the annular shell 41 is mainly used to separate the exhaust gas in the exhaust chamber 11 of the compressor and the reflux of the oil, so as to prevent the reflux of the oil from being affected by the exhaust gas in the exhaust chamber 11 below the motor 20, thereby ensuring that an effective oil circulation can be formed in the shell 10 of the compressor, thereby ensuring the lubrication and heat dissipation requirements of the friction pair of the pump body assembly 30, and can also effectively reduce the oil discharge rate of the compressor.

[0043] It should be noted that, in the present application, in order to ensure that the refrigerant discharged from the exhaust port of the pump assembly 30 can smoothly pass through the second flow passage 411 and the first flow passage 211 into the exhaust chamber 11 above the motor 20, as shown in FIG. Figures 1 to 7As shown, the pump body assembly 30 has a groove structure 31, and the annular housing 41 includes a first assembly section 412, a first guide section 413 and a second guide section 414, wherein the first end of the first assembly section 412 is extended into the groove structure 31; the first end of the first guide section 413 is connected to the second end of the first assembly section 412, and the area of ​​the flow surface of the first guide section 413 is gradually increased in the direction away from the first assembly section 412; the first end of the second guide section 414 is connected to the second end of the first guide section 413, and the outer peripheral surface of the second guide section 414 is arranged with a gap between the cavity wall surface of the exhaust cavity 11, and the second end of the second guide section 414 is directly or indirectly connected to the housing 10. In this way, the installation reliability of the annular housing 41 is ensured, and the regularity of the compressor is ensured.

[0044] like Figures 1 to 4 As shown, the outer diameter of the first assembly section 412 is d2, the inner diameter of the groove structure 31 is D2, and the distance between the outer circumference of the first assembly section 412 and the groove wall of the groove structure 31 is b, wherein D2-d2=2b, 1mm≤b≤3mm. In this way, by optimizing the distance b between the outer circumference of the first assembly section 412 and the groove wall of the groove structure 31, it is avoided that the annular housing 41 interferes with the groove wall of the groove structure 31 during installation due to the distance b between the outer circumference of the first assembly section 412 and the groove wall of the groove structure 31 being too small, and it is also avoided that the refrigerant discharged from the exhaust port of the pump body assembly 30 leaks from the gap between the outer circumference of the first assembly section 412 and the groove wall of the groove structure 31 due to the distance b between the outer circumference of the first assembly section 412 and the groove wall of the groove structure 31 being too large, thereby ensuring the diversion reliability of the diversion part 40.

[0045] like Figures 1 to 4 As shown, the outer diameter of the second guide section 414 is d1, the cavity diameter of the exhaust cavity 11 is D1, and the distance between the outer peripheral surface of the second guide section 414 and the cavity wall surface of the exhaust cavity 11 is a, wherein D1-d1=2a, 1mm≤a≤3mm. In this way, by optimizing the distance a between the outer peripheral surface of the second guide section 414 and the cavity wall surface of the exhaust cavity 11, it is avoided that the annular housing 41 interferes with the inner wall surface of the housing 10 during installation due to the distance a between the outer peripheral surface of the second guide section 414 and the cavity wall surface of the exhaust cavity 11 being too small, and it is also avoided that the area of ​​the flow surface of the second guide section 414 is too small due to the distance a between the outer peripheral surface of the second guide section 414 and the cavity wall surface of the exhaust cavity 11 being too large, thereby ensuring that the second guide section 414 has a sufficiently large flow surface.

[0046] like Figures 1 to 7As shown, the annular housing 41 further includes a third flow guide section 415, a first end of the third flow guide section 415 is connected to a second end of the second flow guide section 414, a second end of the third flow guide section 415 is directly or indirectly connected to the housing 10, and an area of ​​a flow surface of the third flow guide section 415 is gradually reduced in a direction away from the second flow guide section 414. In this way, it is ensured that the refrigerant can smoothly enter the first flow channel 211 from the second flow channel 411.

[0047] like Figure 1 and Figure 2 As shown, the motor 20 further includes an insulating frame 23, which is disposed on the outer peripheral side of the stator assembly 22. The insulating frame 23 has a first clamping structure 231, and the third guide section 415 is provided with a second clamping structure 416 for clamping with the first clamping structure 231. In this way, the convenience of installation or removal of the annular housing 41 is ensured.

[0048] Optionally, the first clamping structure 231 is a clamping hook, and the second clamping structure 416 is a hook, so that the annular shell 41 is mounted on the insulating frame 23 in a hanging manner.

[0049] like Figure 4 and Figure 6 As shown, the annular housing 41 further includes a second assembly section 417, which is connected to the second end of the third guide section 415, and the second clamping structure 416 is located on the outer peripheral side of the second assembly section 417. In this way, the installation reliability of the second clamping structure 416 is ensured.

[0050] like Figures 1 to 4 As shown, the outer diameter of the second assembly section 417 is d3, the insulating frame 23 is annular, the inner diameter of the insulating frame 23 at a position opposite to the second assembly section 417 is D3, and the distance between the outer circumference of the second assembly section 417 and the inner wall of the insulating frame 23 is c, wherein D3-d3=2c, 0.5mm≤c≤2mm. In this way, by optimizing the distance c between the outer circumference of the second assembly section 417 and the inner wall of the insulating frame 23, it is avoided that the annular housing 41 interferes with the inner wall of the insulating frame 23 during installation due to the distance c between the outer circumference of the second assembly section 417 and the inner wall of the insulating frame 23 is too small, and it is also avoided that the area of ​​the flow surface of the second assembly section 417 is too small due to the distance c between the outer circumference of the second assembly section 417 and the inner wall of the insulating frame 23 is too large, thereby ensuring that the second assembly section 417 has a sufficiently large flow surface.

[0051] like Figures 1 to 4As shown, along the axial direction of the rotor assembly 21, the distance from the end surface of the first assembly section 412 to the end surface of the second assembly section 417 is h1, and the distance from the groove bottom surface of the groove structure 31 to the bottom of the stator assembly 22 is H1, wherein H1-h1=f, 0.5mm≤f≤2mm. In this way, while ensuring the compactness of the compressor, the compressor is ensured to have sufficient installation space to install the annular housing 41, which is conducive to improving the convenience of installation or disassembly of the annular housing 41.

[0052] like Figures 1 to 4 As shown, along the axial direction of the rotor assembly 21, the distance from the end face of the first end of the first guide section 413 to the end face of the second end of the third guide section 415 is h2, and the distance from the notch of the groove structure 31 to the bottom end face of the insulating skeleton 23 is H2, wherein H2-5mm≤h2≤H2. In this way, during the installation of the annular shell 41, interference between the first guide section 413 of the annular shell 41 and the groove wall surface of the groove structure 31 is avoided, thereby ensuring that the annular shell 41 can be smoothly installed in the exhaust chamber 11 of the compressor.

[0053] It should be noted that in the present application, by optimizing the overall structural dimensions of the annular shell 41, it is ensured that the oil flowing back from the cut edge of the stator assembly 22 and the oil flowing back from the wall of the coil of the stator assembly 22 can smoothly return to the oil pool, while ensuring that the exhaust space of the exhaust chamber 11 located below the motor 20 is large enough; in addition, it is also possible to reduce the oil intake rate of the compressor to avoid liquid hammer that causes the vane to detach and produce a rattling sound.

[0054] like Figures 5 to 7 As shown, a muffler 418 is provided in the circumferential direction of the annular housing 41. In this way, the muffler 418 plays a role in reducing noise, thereby reducing the exhaust noise of the compressor.

[0055] like Figures 5 to 7 As shown, the muffler 418 is a corrugated protrusion structure located in the second guide section 414; or, the muffler 418 is a hemispherical protrusion formed by a depression of a part of the inner wall surface of the annular shell 41. In this way, while ensuring the noise reduction reliability of the muffler 418 of the annular shell 41, it is helpful to reduce the difficulty of processing and manufacturing the muffler 418.

[0056] Optionally, the material of the annular shell 41 can be sheet metal or high-temperature resistant polymer material, which can further reduce the exhaust noise of the compressor.

[0057] Preferably, the annular shell 41 of the present application is made of the same plastic as the insulating frame 23 .

[0058] like Figure 8 and Fig. 9As shown, the stator assembly 22 includes a stator core 221, and a spiral groove 2211 is formed on the outer circumference of the stator core 221. The rotation direction of the spiral groove 2211 is opposite to the rotation direction of the rotor assembly 21. In this way, it is beneficial to reduce the reflux resistance of the oil separated from the exhaust cavity 11 above the motor 20, and also increase the resistance of the airflow passing through the gap between the outer circumference of the stator assembly 22 and the inner wall of the housing 10.

[0059] Optionally, when the rotation direction of the rotor assembly 21 is clockwise, the rotation direction of the spiral groove 2211 of the stator assembly 22 is counterclockwise; when the rotation direction of the rotor assembly 21 is counterclockwise, the rotation direction of the spiral groove 2211 of the stator assembly 22 is clockwise, and the helix angle of the spiral groove 2211 is B, where 10°≤B≤80°.

[0060] Preferably, the helix angle B of the spiral groove 2211 satisfies: 35°≤B≤55°.

[0061] It should be noted that in the present application, most of the oil separated from the exhaust chamber 11 above the motor 20 flows back to the oil pool through the cut edge of the stator assembly 22, and a small part of the oil is intercepted by the coil of the stator assembly 22, and gathers along the wall of the coil to the bottom of the insulating frame 23 and then returns to the oil pool.

[0062] It should be noted that, in the present application, in order to prevent bubbles generated under different working conditions of the compressor and when the operating frequency of the compressor changes from clogging the gap between the outer peripheral surface of the stator assembly 22 and the inner wall surface of the housing 10, the groove cross section of the spiral groove 2211 is optionally polygonal. In this way, even if there are bubbles in the gap between the outer peripheral surface of the stator assembly 22 and the inner wall surface of the housing 10, the interface of the bubbles is usually spherical or hemispherical under the action of surface tension, and it is impossible to fill the entire polygonal spiral groove 2211. There will be gaps at the corners of the polygonal spiral groove 2211, thereby ensuring that the oil can successfully complete the reflux operation.
