Description

Technical Field

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

[0002] Currently, rotary compressors account for the largest share of the household air conditioning market, and crankshaft wear failures are the most frequent cause of compressor malfunctions each year. The main cause of crankshaft failure is insufficient lubrication of the crankshaft sliding parts. For a single-cylinder rotary compressor crankshaft, which consists of a long shaft, a short shaft, and an eccentric shaft, three sliding parts of the main shaft require lubrication. In existing technology, the crankshaft center has an oil guide channel (i.e., the crankshaft center hole) for lubricating oil flow. This center oil hole is typically used with a spiral-structured oil guide vane to achieve the oil pumping function. The spiral-structured oil guide vane is a type of centrifugal pump, requiring crankshaft rotation to pump the lubricating oil.

[0003] However, the oil guide plate has an oil-facing surface and an oil-backing surface that are set opposite to each other. The oil supply on the oil-backing surface of the oil guide plate is naturally insufficient. When the oil guide hole connecting the crankshaft to its sliding part is located close to the oil-backing surface of the oil guide plate, the lubrication effect of the crankshaft sliding part will be affected, which in turn affects the lubrication effect of the crankshaft. Summary of the Invention

[0004] The main objective of this invention is to provide a compressor and an air conditioner having the same, in order to solve the technical problem of poor crankshaft lubrication in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a compressor is provided, comprising: a pump body assembly and a crankshaft, the crankshaft being disposed on the pump body assembly, the crankshaft having an oil guide channel extending along the extension direction of the crankshaft; an oil guide plate disposed within the oil guide channel, at least a portion of the oil guide plate abutting against the inner wall of the oil guide channel to divide the oil guide channel into an oil-facing area and an oil-returning area, wherein the side wall of the crankshaft is further provided with an oil guide hole facing the pump body assembly, the oil guide hole communicating with the oil-facing area or the oil-returning area; a connecting groove is provided on the inner wall of the oil guide channel, one end of the connecting groove communicating with the oil-facing area, and the other end of the connecting groove communicating with the oil-returning area, so that the oil-facing area communicates with the oil-returning area through the connecting groove.

[0006] Furthermore, the oil guide channel is a cylindrical channel, and at least a portion of the connecting groove extends circumferentially along the oil guide channel.

[0007] Furthermore, the connecting groove is a spiral oil groove.

[0008] Furthermore, the cross-section of the spiral oil groove is semi-circular, trapezoidal, rectangular, or triangular.

[0009] Furthermore, the connecting groove is an annular oil groove.

[0010] Furthermore, the sidewall of the oil guide hole is tangent to the bottom of the connecting groove.

[0011] Furthermore, there are multiple oil guide holes, which are spaced apart along the extension direction of the crankshaft. There are also multiple connecting grooves, which are arranged one-to-one with the multiple oil guide holes, and each connecting groove is connected to the corresponding oil guide hole.

[0012] Furthermore, the crankshaft includes a short shaft section and a long shaft section, an oil guide channel runs through the short shaft section and the long shaft section, at least a portion of the oil guide plate is located in the short shaft section, the oil guide hole includes a first oil guide hole disposed in the short shaft section, the connecting groove includes a first connecting groove communicating with the first oil guide hole; the pump body assembly includes: a first flange, the first flange is sleeved on the short shaft section, and the first oil guide hole is radially disposed towards the short shaft section.

[0013] Furthermore, the crankshaft includes a short shaft section, an eccentric section, and a long shaft section connected in sequence. The oil guide channel passes through the short shaft section, the eccentric section, and the long shaft section in sequence. The oil guide plate is located in the short shaft section and the eccentric section. The oil guide hole includes a second oil guide hole. The connecting groove includes a second connecting groove. Both the second oil guide hole and the connecting groove are located at the eccentric section. The second connecting groove communicates with the second oil guide hole.

[0014] According to another aspect of the present invention, an air conditioner is provided, the air conditioner including a compressor, the compressor being the compressor provided above.

[0015] By applying the technical solution of this invention, during operation, since the oil-facing zone is connected to the back oil-facing zone via a connecting groove, the lubricating oil in the oil-facing zone and the back oil-facing zone can flow to each other, thereby improving the uniformity of the lubricating oil in the oil-facing and back oil-facing zones. Thus, regardless of whether the oil guide hole is connected to the oil-facing zone or the back oil-facing zone, lubricating oil can smoothly enter the oil guide hole, facilitating lubrication between the crankshaft and the pump body assembly opposite to the oil guide hole, thereby improving the lubrication effect on the crankshaft. Therefore, the technical solution provided by this embodiment can solve the technical problem of poor crankshaft lubrication in the prior art. Attached Figure Description

[0029] 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.

[0030] like Figures 1 to 10As shown, according to Embodiment 1 of the present invention, a compressor 1 is provided. The compressor 1 includes a pump body assembly, a crankshaft 6, and an oil guide plate 11. The crankshaft 6 passes through the pump body assembly and has an oil guide channel 61 extending along the extension direction of the crankshaft 6. The oil guide plate 11 is disposed within the oil guide channel 61, and at least a portion of the oil guide plate 11 abuts against the inner wall of the oil guide channel 61, thereby dividing the oil guide channel 61 into an oil-facing area and an oil-repellent area. Specifically, in this embodiment, the oil guide plate 11 has an oil-facing surface and an oil-repellent surface arranged opposite to each other. The oil-facing surface and the inner wall of the oil guide channel 61 form an oil-facing area, and the oil-repellent surface and the inner wall of the oil guide channel 61 form an oil-repellent area. The oil guide plate 11 has a spiral structure to facilitate pumping the lubricating oil 12 at the bottom of the oil guide channel 61 to the upper part of the oil guide channel 61, so as to fully lubricate the entire crankshaft 6 and improve the lubrication effect. The crankshaft 6 has an oil guide hole on its side wall that faces the pump assembly and is connected to the oil-facing area or the back oil-facing area. The inner wall of the oil guide channel 61 has a connecting groove, one end of which is connected to the oil-facing area and the other end of which is connected to the back oil-facing area, so that the oil-facing area is connected to the back oil-facing area through the connecting groove.

[0031] With this structural arrangement, during operation, the oil-facing zone is connected to the back oil-facing zone via a connecting groove, allowing the lubricating oil 12 in both zones to flow freely. This improves the uniformity of the lubricating oil 12 in both zones. Thus, regardless of whether the oil guide hole connects to the oil-facing or back oil-facing zone, lubricating oil 12 can smoothly enter the guide hole, facilitating lubrication between the crankshaft 6 and the pump body assembly opposite the guide hole, thereby improving the lubrication effect on the crankshaft 6. Therefore, the technical solution provided in this embodiment can solve the technical problem of poor lubrication effect of the crankshaft 6 in the prior art.

[0032] In this embodiment, the oil guide channel 61 is a cylindrical channel, and at least a portion of the connecting groove extends circumferentially along the oil guide channel 61 to better connect the oil-facing area and the back oil-facing area, thereby improving the uniformity of the lubricating oil 12.

[0033] Specifically, the connecting groove can be a spiral oil groove 62. The above structure is simple, easy to manufacture, and also facilitates the connection between the oil-facing area and the back oil-facing area.

[0034] Specifically, the cross-section of the spiral oil groove 62 can be semi-circular, trapezoidal, rectangular, or triangular.

[0035] Alternatively, the connecting groove in this embodiment can be an annular oil groove 63. The annular oil groove 63 has a simple structure, is easy to manufacture, and also facilitates the connection between the oil-facing area and the back oil-facing area.

[0036] In this embodiment, the sidewall of the oil guide hole is tangent to the bottom of the connecting groove. This structural arrangement facilitates the smooth entry of lubricating oil 12 from the connecting groove into the oil guide hole, thereby improving the uniformity of the lubricating oil 12 distribution and thus better lubricating the crankshaft 6.

[0037] Specifically, in this embodiment, there can be multiple oil guide holes, which are spaced apart along the extension direction of the crankshaft 6. There are also multiple connecting grooves, each corresponding to one of the oil guide holes. Each connecting groove communicates with its corresponding oil guide hole, facilitating lubrication of different parts of the crankshaft 6 through the connecting grooves and corresponding oil guide holes, thus improving lubrication of the crankshaft 6. Specifically, when the connecting groove is an annular oil groove 63, both the oil guide holes and the connecting groove can be multiple. When the connecting groove is a spiral oil groove 62, both the oil guide holes and the connecting groove can be multiple; alternatively, there can be one spiral oil groove 62 with a relatively long length, and multiple oil guide holes. Specifically, in this embodiment, the connecting groove is located on the outside of the oil guide plate 11. The height of the connecting groove depends on the height of the oil guide plate 11, and the height of the connecting groove corresponds to the height of the oil guide plate 11, facilitating communication between the oil-facing area and the oil-returning area of ​​the oil guide plate 11.

[0038] In this embodiment, the crankshaft 6 includes a short shaft section 68 and a long shaft section 610. An oil guide channel 61 passes through both the short shaft section 68 and the long shaft section 610. At least a portion of the oil guide plate 11 is located within the short shaft section 68. The oil guide hole includes a first oil guide hole 64, which is disposed within the short shaft section 68. The connecting groove includes a first connecting groove, which communicates with the first oil guide hole 64. The pump body assembly includes a first flange 10 and a second flange 5. The first flange 10 is fitted onto the short shaft section 68, and the second flange 5 is fitted onto the long shaft section 610. The first flange 10 is located below the second flange 5; the first flange 10 is a lower flange, and the second flange 5 is an upper flange. The first oil guide hole 64 is radially arranged towards the short shaft section 68. This structural arrangement facilitates the entry of lubricating oil 12 through the first connecting groove into the first oil guide hole 64, thereby ensuring sufficient lubrication between the crankshaft 6 and the first flange 10 and improving the lubrication effect on the crankshaft 6. The connecting groove here can be an annular oil groove 63 or a spiral oil groove 62.

[0039] Specifically, in this embodiment, the short shaft section 68 is located below the long shaft section 610. When the crankshaft 6 rotates, it drives the oil guide plate 11 to rotate synchronously, so as to pump the lubricant in the oil guide channel 61 from the bottom of the short shaft section 68 towards the long shaft section 610, thereby improving the overall lubrication effect of the crankshaft 6. The second oil guide hole 65 is located at the end of the crankshaft 6 with a smaller eccentricity.

[0040] In this embodiment, the crankshaft 6 includes a short shaft section 68, an eccentric section 69, and a long shaft section 610 connected in sequence. An oil guide channel 61 passes through the short shaft section 68, the eccentric section 69, and the long shaft section 610 in sequence. An oil guide plate 11 is located within the short shaft section 68 and the eccentric section 69. The oil guide hole includes a second oil guide hole 65, and the connecting groove includes a second connecting groove. Both the second oil guide hole 65 and the connecting groove are located at the eccentric section 69, and the second connecting groove communicates with the second oil guide hole 65. This structural arrangement facilitates lubrication of the eccentric section 69 through the second connecting groove and the second oil guide hole 65, thereby improving the lubrication effect on the crankshaft 6. Specifically, the connecting groove here can be a spiral oil groove 62 or an annular oil groove 63.

[0041] In this embodiment, the compressor 1 also includes a housing 2, a stator 31, a rotor 32, a muffler 4, a cylinder 7, a vane 8, rollers 9, and an exhaust valve 13. During operation, the outer circle of the roller 9 fits tightly with the head of the vane 8, causing the cavity formed by the inner circle of the cylinder 7 and the outer circle of the roller 9 to be divided into two by the vane 8, forming an intake chamber (low-pressure chamber) and a compression chamber (high-pressure chamber). The low-temperature, low-pressure refrigerant from the refrigeration system enters the intake low-pressure chamber through the intake port of the cylinder 7. Driven by the motor rotor 32, the crankshaft 6 rotates synchronously, and the rollers 9 on the eccentric part of the crankshaft 6 also rotate accordingly. The low-temperature, low-pressure refrigerant in the intake low-pressure chamber of the cylinder 7 is gradually compressed due to the change in volume, and then compressed into a high-temperature, high-pressure refrigerant. After being compressed, it flows from the oblique cut of the high-pressure compression chamber of the cylinder 7 through the flange exhaust port and is discharged after the exhaust valve 13 is opened, finally returning to the refrigeration system to complete the refrigerant compression process of the entire refrigeration cycle.

[0042] During the operation of compressor 1, the lubricating oil 12 inside the pump body assembly flows as follows: the lubricating oil 12 at the bottom of the compressor housing 2 is immersed in the skirt of the upper flange (second flange 5) of the pump body assembly. During the operation of compressor 1, the motor rotor 32 drives the crankshaft 6 to rotate, and at the same time, the crankshaft 6 also drives the oil guide plate 11 assembled at its central oil hole to rotate. The rotation of the spiral structured oil guide plate 11 causes the lubricating oil 12 to flow from the bottom of the short shaft section 68 of crankshaft 6 into its central oil hole, and rises along the outer peripheral edge of the oil guide plate 11. The lubricating oil 12 flows sequentially into the first oil guide hole 64, the second oil guide hole 65, the third oil guide hole 66, and the fourth oil guide hole 67. Then, the lubricating oil 12 flows through the inner oil groove (first connecting groove) of the lower flange (first flange 10), the vertical groove of the eccentric part of crankshaft 6, and the inner hole of the upper flange to complete the lubrication between the short shaft of crankshaft 6 and the lower flange, the eccentric part of crankshaft 6 and the roller 9, and the long shaft of crankshaft 6 and the upper flange. It flows out from the opening end of the oil groove in the inner hole of the lower flange and the spiral oil groove 62 in the inner hole of the upper flange, and converges at the bottom of the shell 2.

[0043] When the oil guide plate 11 is installed in the center oil hole of the short shaft of the conventional crankshaft 6, and the oil guide hole of the short shaft of the crankshaft 6 is located on the oil-back side of the oil guide plate 11, the lubricating oil 12 is mainly concentrated on its oil-facing side because the oil guide plate 11 is a centrifugal pump. The oil distribution on its oil-back side is less, resulting in less oil flowing into the oil guide hole of the short shaft of the crankshaft 6. This ultimately affects the lubrication between the crankshaft 6 and the lower flange.

[0044] As shown in the figure, after the crankshaft 6 short shaft center oil hole is provided with an arc-shaped spiral oil groove 62 and equipped with an oil guide plate 11, the cross-sectional view of the oil guide hole position is shown. At this time, the presence of the spiral oil groove 62 in the crankshaft 6 center oil hole connects the oil-facing surface and the back oil-facing surface of the oil guide plate 11, thereby allowing the lubricating oil 12 on the oil-facing surface to flow into the back oil-facing surface, so that the oil volume on both sides is evenly distributed.

[0045] Specifically, since the spiral oil groove 62 is tangent to the oil guide hole, the lubricating oil 12 on the oil-facing surface of the oil guide plate 11 flows more smoothly into the oil guide hole after passing through the spiral oil groove 62, further increasing the amount of oil flowing into the oil guide hole.

[0046] As shown in the figure, the spiral oil groove 62 can also be replaced by an annular oil groove 63 in the center oil hole of the crankshaft 6. Essentially, they are the same and can be understood as a variation of the spiral oil groove 62. To reduce the machining difficulty of the crankshaft 6, the annular oil groove 63 is only provided at the location of the oil guide hole in the center oil hole of the crankshaft 6. Similarly, the presence of the annular oil groove 63 connects the oil-facing and back-facing surfaces of the oil guide plate 11, allowing the lubricating oil 12 on the oil-facing surface to flow into the back-facing surface, resulting in a more even distribution of oil on both sides. Furthermore, the annular groove is tangent to the oil guide hole, allowing the lubricating oil 12 to flow more smoothly into the oil guide hole.

[0047] As shown in the figure, the arc-shaped spiral oil groove 62 can be replaced with a trapezoidal spiral oil groove 62, which functions the same as in Embodiment 1, serving to guide the oil guide plate 11 to both sides.

[0048] This invention is also applicable to single-cylinder, double-cylinder, and above rotor 32-type compressors 1, etc. In this invention, a spiral oil groove 62 or annular oil groove 63 is provided in the central oil hole of the crankshaft 6 (the central oil hole is also the oil guide channel 61). This structure connects the oil-facing and back-facing surfaces of the oil guide plate 11, thereby achieving uniform oil distribution on both sides of the oil guide plate 11 during the oil pumping process. Furthermore, since the spiral oil groove 62 and annular oil groove 63 are tangential to the oil guide hole, this ensures a consistent oil supply regardless of whether the oil guide hole of the crankshaft 6 is located on the oil-facing or back-facing surface of the oil guide plate 11.

[0049] Embodiment 2 of the present invention provides an air conditioner, which includes a compressor 1, and the compressor 1 is the compressor 1 provided in the above embodiment.

[0050] As can be seen from the above description, the above embodiments of the present invention achieve the following technical effects: the present invention solves the problem of uneven oil distribution in the oil-facing and oil-backing areas during the oil pumping process of the spiral structure oil guide plate; and solves the problem of insufficient oil intake when the oil guide hole is located in the oil-backing area of ​​the oil guide plate.
