Utility Model Content
[0003] The utility model aims to at least solve or improve the technical problem of severe wear between the orbiting scroll and the stationary scroll of a compressor in the prior art.
[0004] To this end, a first aspect of the present invention provides a compressor.
[0005] A second aspect of the present invention provides an electrical device.
[0006] In view of this, according to the first aspect of the present invention, the present invention proposes a compressor, comprising: a crankshaft, the crankshaft having a first oil guide channel; a movable scroll, connected to the crankshaft, the movable scroll having a second oil guide channel; a fixed scroll, matched with the movable scroll, the fixed scroll comprising a first disk body and a first volute, the fixed scroll having a first oil groove and a second oil groove, the second oil groove being located on the outside of the first oil groove, the first oil groove being arranged on the end face of the first disk body and the end face of the first volute, and the second oil groove being arranged on the end face of the first disk body; wherein, when the compressor is running, the first oil guide channel and the second oil guide channel transport oil to the first oil groove and the second oil groove.
[0007] The compressor proposed by the utility model includes a crankshaft, an orbiting scroll and a stationary scroll. The orbiting scroll and the stationary scroll cooperate with each other, and the crankshaft and the orbiting scroll are connected. The crankshaft can drive the scroll to move, so that the orbiting scroll and the stationary scroll do work to compress the refrigerant.
[0008] In addition, the crankshaft has a first oil guide channel, the movable scroll has a second oil guide channel, the first oil guide channel and the second oil guide channel are connected, the fixed scroll includes a first disk body and a first vortex, and the fixed scroll also has a first oil groove and a second oil groove, the first oil groove and the second oil groove are located on the end face of the fixed scroll, specifically, the first oil groove is located on the end face of the first disk body and the end face of the first vortex, the second oil groove is located on the end face of the first disk body, and the first oil groove and the second oil groove are both at least partially located on the end face of the first disk body, thereby making it possible for the first oil groove and the second oil groove to be connected to the second oil guide channel.
[0009] Moreover, when the compressor is running, the first oil guide channel and the second oil guide channel transport oil to the first oil groove and the second oil groove, thereby making the end surface of the first disk body and the end surface of the first volute better lubricated, and reducing the contact area between the orbiting scroll and the fixed scroll, thereby reducing the wear between the orbiting scroll and the fixed scroll, and reducing the possibility of leakage between the orbiting scroll and the fixed scroll.
[0010] In addition, the compressor according to the above technical solution provided by the present invention may also have the following additional technical features:
[0011] In some embodiments, optionally, the first oil groove includes: a first groove, located on the end surface of the first disk body, and when the compressor is running, the first groove and the second oil guide channel are intermittently connected; a second groove, at least part of the second groove is located on the first vortex, the second groove is connected to the first groove, and the second groove extends along the spiral direction of the first vortex.
[0012] In this embodiment, the first oil groove includes a first groove and a second groove, the first groove is arranged on the end surface of the first disk body, at least part of the second groove is arranged on the first vortex, and the second groove is connected to the first groove. When the compressor is running, the orbiting scroll moves relative to the fixed scroll, so that the position of the second oil guide channel changes, so that the first groove and the second oil guide channel are intermittently connected, so that the oil can form a certain pressure to ensure that a sufficient amount of oil is injected into the second groove at a single time, thereby ensuring the lubrication effect of the orbiting scroll and the fixed scroll.
[0013] Furthermore, the second groove extends along the spiral direction of the first volute, thereby improving the lubrication effect between the first volute and the orbiting scroll.
[0014] Furthermore, since the first oil guide channel and the second oil guide channel are connected to the first oil tank to transport oil, the high-pressure area in the compressor will be exhausted to the first oil tank. Therefore, the intermittent connection method can reduce the exhaust volume of the high-pressure area in the compressor and ensure the performance of the compressor.
[0015] In some embodiments, optionally, the first oil groove further includes: a third groove, located in the first disc body, the third groove is arranged around the first volute, and the third groove is connected to the first groove.
[0016] In this embodiment, the first oil groove also includes a third groove, which is connected to the first groove. The third groove is located in the first disk body and is arranged around the first vortex. When the compressor is running, the movable scroll moves relative to the fixed scroll, thereby changing the position of the second oil guide channel, so that the first groove and the second oil guide channel are intermittently connected, thereby limiting the exhaust volume of the high-pressure area to ensure that there is sufficient lubricating oil in the third groove while ensuring the pressure in the high-pressure area of the compressor, thereby ensuring the lubrication effect of the movable scroll and the fixed scroll.
[0017] Furthermore, the third groove further improves the lubrication effect between the orbiting scroll and the fixed scroll, thereby reducing wear between the orbiting scroll and the fixed scroll.
[0018] In some embodiments, optionally, the first groove includes a first side wall and a second side wall, the first side wall is close to the first volute, and both the first side wall and the second side wall protrude toward the first volute.
[0019] In this embodiment, the first groove includes a first side wall and a second side wall, the first side wall is close to the first vortex, and the first side wall and the second side wall both protrude toward the first vortex, thereby adapting to the movement trajectory of the movable scroll disk, and increasing the connection time between the first groove and the second oil guide channel while reducing the occupied area.
[0020] In some embodiments, optionally, the second groove and the third groove are both connected to the first side wall, the first side wall is an arc-shaped structure, and the second side wall is an arc-shaped structure.
[0021] In this embodiment, the second groove and the third groove are both connected to the first side wall, and after the oil enters the first groove, the second side wall can push the oil toward the first side wall, thereby pushing the oil into the second groove and the third groove, ensuring that there is sufficient oil in the second groove and the third groove, ensuring the lubrication effect between the orbiting scroll and the fixed scroll.
[0022] The first side wall is an arc-shaped structure, thereby reducing the impact of oil on the first side wall, and can provide a guiding path for the oil to facilitate the oil to enter the second groove and the third groove. The second side wall is an arc-shaped structure, which reduces the impact of oil on the second side wall, so that the oil can smoothly enter the second groove and the third groove.
[0023] Furthermore, the arc-shaped structure of the first side wall and the second side wall is more consistent with the motion trajectory of the orbiting scroll, thereby increasing the communication time between the second oil guide channel and the first groove, thereby increasing the oil inlet amount of the first groove.
[0024] In some embodiments, optionally, along the spiral direction of the first volute, the second groove extends along the first volute for at least one circle.
[0025] In this embodiment, since the first volute is a spiral structure, the second groove can be extended along the first volute for at least one circle along the spiral direction of the first volute, ensuring sufficient oil lubrication between the first volute and the orbiting scroll, thereby reducing the wear between the orbiting scroll and the fixed scroll, thereby ensuring the sealing between the first volute and the orbiting scroll.
[0026] In some embodiments, optionally, the second oil groove includes: a fourth groove, located on the end surface of the first disk body, and when the compressor is running, the fourth groove and the second oil guide channel are intermittently connected; a fifth groove, located on the end surface of the first disk body, the fifth groove is arranged around the first oil groove, and the fifth groove and the fourth groove are connected.
[0027] In this embodiment, the second oil groove includes a fourth groove and a fifth groove, the fourth groove and the fifth groove are connected, and the fourth groove and the fifth groove are both arranged on the end face of the first disk body. When the compressor is running, the movable scroll moves relative to the fixed scroll, thereby changing the position of the second oil guide channel, so that the fourth groove and the second oil guide channel are intermittently connected, so that the oil can form a certain pressure to ensure that a sufficient amount of oil is injected into the fifth groove at a single time, thereby ensuring the lubrication effect of the movable scroll and the fixed scroll.
[0028] In addition, since the first oil guide channel and the second oil guide channel will connect the high-pressure area and the low-pressure area in the compressor when they are connected to the first oil tank, the intermittent connection method can reduce the exhaust volume from the high-pressure area to the low-pressure area in the compressor, thereby ensuring the compression effect of the compressor on the refrigerant and ensuring the performance of the compressor.
[0029] In some embodiments, optionally, the depth of the fifth groove is greater than the depth of the fourth groove.
[0030] In this embodiment, the depth of the fifth groove is greater than that of the fourth groove, thereby limiting the amount of oil entering the fifth groove and reducing the amount of exhaust from the high-pressure area to the low-pressure area, thereby ensuring the performance of the compressor.
[0031] In some embodiments, optionally, during one rotation of the orbiting scroll, when the fourth groove and the second oil guide channel are in communication, the rotation angle of the orbiting scroll is less than or equal to 30°.
[0032] In this embodiment, when the compressor is running, the motion trajectory of the movable scroll is circular, and the movable scroll moves one circle for 360°. During the process of the movable scroll rotating one circle, when the fourth groove and the second oil guide channel are connected, the rotation angle of the movable scroll is less than or equal to 30°, and in other ranges greater than or equal to 330°, the fourth groove and the second oil guide channel are not connected, thereby reducing the exhaust volume from the high-pressure area to the low-pressure area, thereby ensuring the performance of the compressor.
[0033] In some embodiments, optionally, the first oil tank and the second oil tank are independent of each other.
[0034] In this embodiment, during the movement of the movable scroll, part of the second oil tank will be connected to the low-pressure area in the compressor, and the first oil tank and the second oil tank are set to be independent of each other and not connected. This can reduce the connection time between the high-pressure area and the low-pressure area of the compressor, thereby ensuring the performance of the compressor.
[0035] According to a second aspect of the present invention, the present invention provides an electrical device, including: the compressor provided by the embodiment of the first aspect.
[0036] The electrical equipment proposed in the present invention includes the compressor provided in the first embodiment, and therefore has the compressor provided in the first embodiment, which will not be described one by one here.

DETAILED DESCRIPTION
[0050] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.
[0051] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0052] Refer to the following Figures 1 to 9 To describe a compressor 100 and an electrical device according to some embodiments of the present invention. Figures 5 to 8 The arrows in the diagram indicate the direction of oil flow.
[0053] like Figure 1 and Figure 2 As shown, according to the first aspect of the present invention, the present invention proposes a compressor 100, which includes a crankshaft 110, a movable scroll 120 and a fixed scroll 130. The crankshaft 110 and the movable scroll 120 are connected to drive the movable scroll 120 to rotate synchronously, and the fixed scroll 130 and the movable scroll 120 cooperate with each other.
[0054] like Figures 1 to 8As shown, the crankshaft 110 has a first oil guide channel 112, which can be connected to the oil pool in the compressor 100. The movable scroll 120 has a second oil guide channel 122, and the first oil guide channel 112 and the second oil guide channel 122 are connected. The fixed scroll 130 includes a first disk body 132 and a first volute 134, and the first volute 134 is arranged on the first disk body 132. The fixed scroll 130 has a first oil groove 136 and a second oil groove 138, and the second oil groove 138 is located on the outside of the first oil groove 136. Part of the first oil groove 136 is arranged on the end surface of the first disk body 132 facing the crankshaft 110, and the other part of the first oil groove 136 is arranged on the end surface of the first volute 134 facing the crankshaft 110. The second oil groove 138 is arranged on the end surface of the first disk body 132 facing the crankshaft 110.
[0055] When the compressor 100 is running, the oil in the oil pool of the compressor 100 is transported to the first oil groove 136 and the second oil groove 138 through the first oil guide channel 112 and the second oil guide channel 122 .
[0056] The compressor 100 proposed in the present invention includes a crankshaft 110, an orbiting scroll 120 and a stationary scroll 130. The orbiting scroll 120 and the stationary scroll 130 cooperate with each other, and the crankshaft 110 and the orbiting scroll 120 are connected. The crankshaft 110 can drive the scroll 120 to move, so that the orbiting scroll 120 and the stationary scroll 130 do work to compress the refrigerant.
[0057] In addition, the crankshaft 110 has a first oil guide channel 112, the orbiting scroll 120 has a second oil guide channel 122, the first oil guide channel 112 and the second oil guide channel 122 are connected, the fixed scroll 130 includes a first disk body 132 and a first vortex 134, and the fixed scroll 130 also has a first oil groove 136 and a second oil groove 138. The first oil groove 136 and the second oil groove 138 are located on the end surface of the fixed scroll 130. Specifically, the first oil groove 136 is located on the end surface of the first disk body 132 and the end surface of the first vortex 134, and the second oil groove 138 is located on the end surface of the first disk body 132. The first oil groove 136 and the second oil groove 138 are both at least partially located on the end surface of the first disk body 132, so that the first oil groove 136 and the second oil groove 138 have the possibility of being connected to the second oil guide channel 122.
[0058] Moreover, when the compressor 100 is running, the first oil guide channel 112 and the second oil guide channel 122 transport oil to the first oil groove 136 and the second oil groove 138, thereby making the end surface of the first disk body 132 and the end surface of the first vortex 134 better lubricated, and reducing the contact area between the orbiting scroll 120 and the fixed scroll 130, thereby reducing the wear between the orbiting scroll 120 and the fixed scroll 130, and reducing the possibility of air leakage between the orbiting scroll 120 and the fixed scroll 130, effectively improving the reliability and performance of the compressor 100, and reducing the power consumption of the compressor 100.
[0059] The compressor 100 provided by the present invention utilizes the orbiting scroll 120 to guide the high-pressure oil to the end surface of the fixed scroll 130, that is, utilizes the orbiting scroll 120 to guide the high-pressure oil to between the fixed scroll 130 and the orbiting scroll 120, thereby minimizing the large-area contact between the orbiting scroll 120 and the fixed scroll 130, and guides oil through the first oil guide channel 112, the second oil guide channel 122, the first oil groove 136 and the second oil groove 138 to form an oil film lubrication between the orbiting scroll 120 and the fixed scroll 130.
[0060] like Figure 3 and Figure 4 As shown, in some embodiments, optionally, the first oil groove 136 includes a first groove 1362 and a second groove 1364, and the first groove 1362 is arranged on the end surface of the first disk body 132 facing the crankshaft 110. When the compressor 100 is running, the first groove 1362 and the second oil guide channel 122 are intermittently connected, and at least part of the second groove 1364 is arranged on the end surface of the first volute 134 facing the crankshaft 110. Another part of the second groove 1364 can be arranged on the end surface of the first disk body 132 facing the crankshaft 110. The second groove 1364 is connected to the first groove 1362, and the second groove 1364 extends along the spiral direction BA of the first volute 134.
[0061] In this embodiment, the first oil groove 136 includes a first groove 1362 and a second groove 1364. The first groove 1362 is provided on the end surface of the first plate body 132, and at least a portion of the second groove 1364 is provided on the first volute 134. In addition, the second groove 1364 and the first groove 1362 are connected. When the compressor 100 is running, the orbiting scroll 120 moves relative to the fixed scroll 130, thereby changing the position of the second oil guide channel 122, so that the first groove 1362 and the second oil guide channel 122 are intermittently connected, as shown in FIG. Figure 5 and Figure 6As shown, when the first groove 1362 and the second oil guide channel 122 are connected, the oil can enter the first groove 1362 through the second oil guide channel 122, and then enter the second groove 1364 from the first groove 1362, so that the oil can form a certain pressure to ensure that a sufficient amount of oil is injected into the second groove 1364 at a single time, thereby ensuring the lubrication effect of the orbiting scroll 120 and the fixed scroll 130.
[0062] Also, the second groove 1364 extends along the spiral direction BA of the first scroll 134 , thereby improving lubrication between the first scroll 134 and the orbiting scroll 120 .
[0063] Furthermore, since the first oil guide channel 112 and the second oil guide channel 122 are connected to the first oil groove 136 to transport oil, the high-pressure area in the compressor 100 will be exhausted to the first oil groove 136. Therefore, the intermittent connection method can reduce the exhaust volume of the high-pressure area in the compressor 100, thereby ensuring the performance of the compressor 100.
[0064] The second groove 1364 is spiral-shaped, and at least a portion of the second groove is disposed between the inner profile and the outer profile of the first volute 134 .
[0065] like Figure 3 and Figure 4 As shown, in some embodiments, optionally, the first oil groove 136 also includes a third groove 1366, and the third groove 1366 is arranged on the end surface of the first disk body 132 facing the crankshaft 110. The third groove 1366 is arranged around the first vortex 134, and the third groove 1366 and the first groove 1362 are connected.
[0066] In this embodiment, the first oil groove 136 also includes a third groove 1366, and the third groove 1366 is connected to the first groove 1362. The third groove 1366 is located in the first disk body 132 and is arranged around the first vortex 134. When the compressor 100 is running, the movable scroll 120 moves relative to the fixed scroll 130, so that the position of the second oil guide channel 122 changes, so that the first groove 1362 and the second oil guide channel 122 are intermittently connected, thereby limiting the exhaust of the high-pressure area to ensure that there is sufficient lubricating oil in the third groove 1366 while ensuring the pressure in the high-pressure area of the compressor 100, thereby ensuring the lubrication effect of the movable scroll 120 and the fixed scroll 130.
[0067] Furthermore, the third grooves 1366 further enhance the lubrication effect between the orbiting scroll 120 and the fixed scroll 130 , thereby reducing wear between the orbiting scroll 120 and the fixed scroll 130 .
[0068] The third groove 1366 is a ring-shaped structure.
[0069] like Figure 4 As shown, in some embodiments, optionally, the first groove 1362 includes a first side wall 1368 and a second side wall 1370, the first side wall 1368 and the second side wall 1370 are connected, the first side wall 1368 is close to the first vortex tooth 134, the second side wall 1370 is located on the side of the first side wall 1368 away from the first vortex tooth 134, the first side wall 1368 protrudes toward the first vortex tooth 134, and the second side wall 1370 protrudes toward the first vortex tooth 134.
[0070] In this embodiment, the first groove 1362 includes a first side wall 1368 and a second side wall 1370. The first side wall 1368 is close to the first vortex 134. The first side wall 1368 and the second side wall 1370 both protrude toward the first vortex 134, thereby adapting to the movement trajectory of the movable scroll 120. While reducing the occupied area, the connection time between the first groove 1362 and the second oil guide channel 122 is increased, thereby ensuring the lubrication and sealing effects between the movable scroll 120 and the fixed scroll 130.
[0071] like Figure 4 As shown, in some embodiments, optionally, the first groove 1362 includes a first side wall 1368 and a second side wall 1370, the first side wall 1368 and the second side wall 1370 are connected, and the first side wall 1368 is an arc-shaped structure, and the second side wall 1370 is an arc-shaped structure, wherein the first side wall 1368 is close to the first vortex 134, the second side wall 1370 is located on the side of the first side wall 1368 away from the first vortex 134, the first side wall 1368 protrudes toward the first vortex 134, the second side wall 1370 protrudes toward the first vortex 134, and the second groove 1364 and the third groove 1366 are arranged on the first side wall 1368.
[0072] In this embodiment, the first groove 1362 includes a first side wall 1368 and a second side wall 1370, and the first side wall 1368 is close to the first vortex tooth 134. The first side wall 1368 and the second side wall 1370 both protrude toward the first vortex tooth 134, and then after the oil enters the first groove 1362, the second side wall 1370 can push the oil toward the first side wall 1368, thereby pushing the oil into the second groove 1364 and the third groove 1366, ensuring that there is sufficient oil in the second groove 1364 and the third groove 1366, ensuring the lubrication effect between the movable scroll plate 120 and the fixed scroll plate 130.
[0073] The first side wall 1368 is an arc-shaped structure, which reduces the impact of oil on the first side wall 1368 and provides a guiding path for the oil to facilitate the oil to enter the second groove 1364 and the third groove 1366. The second side wall 1370 is an arc-shaped structure, which reduces the impact of oil on the second side wall 1370, so that the oil can smoothly enter the second groove 1364 and the third groove 1366.
[0074] In addition, the arc-shaped structure of the first side wall 1368 and the second side wall 1370 is more in line with the movement trajectory of the orbiting scroll 120, thereby increasing the connection time between the second oil guide channel 122 and the first groove 1362, so that the connection area between the first oil groove 136 and the second oil guide channel 122 of the orbiting scroll 120 should be as large as possible, thereby increasing the oil intake of the first groove 1362 and ensuring the lubrication effect between the orbiting scroll 120 and the fixed scroll 130.
[0075] Among them, the first groove 1362 of the first oil groove 136 has a first side wall 1368 close to the contour line that is a regular arc shape, and the second side wall 1370 away from the contour line has two protrusions, and the first side wall 1368 and the second side wall 1370 form a roughly "cat ear shape".
[0076] like Figure 4 As shown, in some embodiments, optionally, along the spiral direction BA of the first volute 134 , the second groove 1364 extends along the first volute 134 for at least one circle.
[0077] In this embodiment, since the first vortex 134 is a spiral structure, the second groove 1364 can extend along the first vortex 134 for at least one circle along the spiral direction BA of the first vortex 134, ensuring that there is sufficient oil lubrication between the first vortex 134 and the orbiting scroll 120, thereby reducing the wear between the orbiting scroll 120 and the fixed scroll 130.
[0078] Along the spiral direction BA of the first volute 134 , the second groove 1364 extends to the innermost circle of the first volute 134 .
[0079] like Figure 4 As shown, in some embodiments, the second oil groove 138 optionally includes a fourth groove 1382 and a fifth groove 1384. The fourth groove 1382 is provided on the end surface of the first plate 132 facing the crankshaft 110. When the compressor 100 is operating, the fourth groove 1382 and the second oil guide channel 122 are intermittently connected. The fifth groove 1384 is provided on the end surface of the first plate 132 facing the crankshaft 110. The fifth groove 1384 surrounds the first oil groove 136 and is connected to the fourth groove 1382. Furthermore, because the fifth groove 1384 surrounds the first oil groove 136, the size of the fifth groove 1384 is larger. When the orbiting scroll 120 moves, a portion of the fifth groove 1384 is connected to the low-pressure area of the compressor 100. The low-pressure area can be understood as the back pressure area on the side of the orbiting scroll 120 facing away from the fixed scroll 130.
[0080] In this embodiment, the second oil groove 138 includes a fourth groove 1382 and a fifth groove 1384, and the fourth groove 1382 and the fifth groove 1384 are connected. The fourth groove 1382 and the fifth groove 1384 are both provided on the end surface of the first plate body 132. When the compressor 100 is running, the orbiting scroll 120 moves relative to the fixed scroll 130, thereby changing the position of the second oil guide channel 122, so that the fourth groove 1382 and the second oil guide channel 122 are intermittently connected, as shown in FIG. Figure 7 and Figure 8 As shown, when the fourth groove 1382 and the second oil guide channel 122 are connected, the oil can enter the fourth groove 1382 through the second oil guide channel 122, and then enter the fifth groove 1384 from the fourth groove 1382, so that the oil can form a certain pressure to ensure that a sufficient amount of oil is injected into the fifth groove 1384 at a single time, thereby ensuring the lubrication effect of the movable scroll 120 and the fixed scroll 130.
[0081] In addition, since the first oil guide channel 112 and the second oil guide channel 122 will connect the high-pressure area and the low-pressure area in the compressor 100 when they are connected to the first oil groove 136, the intermittent connection method can reduce the exhaust volume from the high-pressure area to the low-pressure area in the compressor 100, thereby ensuring the compression effect of the compressor 100 on the refrigerant and ensuring the performance of the compressor 100.
[0082] The fifth groove 1384 is an annular structure, the fourth groove 1382 is a strip-shaped structure, and the inner ring or outer ring of the fourth groove 1382 and the fifth groove 1384 are connected.
[0083] like Figure 9 As shown, in some embodiments, optionally, the depth L2 of the fifth groove 1384 is greater than the depth L1 of the fourth groove 1382 .
[0084] In this embodiment, the depth L2 of the fifth groove 1384 is greater than the depth L1 of the fourth groove 1382, thereby limiting the amount of oil entering the fifth groove 1384 and reducing the exhaust volume from the high-pressure area to the low-pressure area, thereby ensuring the performance of the compressor 100.
[0085] In some embodiments, optionally, during one rotation of the orbiting scroll 120 , when the fourth groove 1382 and the second oil guide channel 122 are in communication, the rotation angle of the orbiting scroll 120 is less than or equal to 30°.
[0086] In this embodiment, when the compressor 100 is running, the motion trajectory of the movable scroll 120 is circular, and the movable scroll 120 rotates one circle for 360°. During the process of the movable scroll 120 rotating one circle, in the case of the fourth groove 1382 and the second oil guide channel 122, the rotation angle of the movable scroll 120 is less than or equal to 30°, and in the other range of the movable scroll 120 rotating greater than or equal to 330°, the fourth groove 1382 and the second oil guide channel 122 are not connected, thereby reducing the exhaust volume from the high-pressure area to the low-pressure area, thereby ensuring the performance of the compressor 100.
[0087] In the process of the movable scroll 120 rotating one circle, in the case of the fourth groove 1382 and the second oil guide channel 122, the rotation angle of the movable scroll 120 can be 30°, 25°, 20°, 15°, 10° or 5°.
[0088] like Figure 4 As shown, in some embodiments, optionally, the first oil groove 136 and the second oil groove 138 are independent of each other.
[0089] In this embodiment, during the movement of the orbiting scroll 120, a portion of the second oil groove 138 will communicate with the low-pressure area within the compressor 100. Therefore, the first oil groove 136 and the second oil groove 138 are independent of each other and are not connected. This can reduce the communication time between the high-pressure area and the low-pressure area of the compressor 100, thereby ensuring the performance of the compressor 100. In some embodiments, the compressor 100 optionally further includes a casing 140, a bracket 150, and a bearing 160. The bearing 160 is located between the orbiting scroll 120 and the crankshaft 110. The bracket 150 is disposed within the casing 140 and is used to support the orbiting scroll 120.
[0090] like Figures 1 to 9 As shown, the compressor 100 provided by the present invention includes: an orbiting scroll 120, a fixed scroll 130, a bearing 160, a crankshaft 110 and a bracket 150. The orbiting scroll 120 and the fixed scroll 130 form a compression chamber. The orbiting scroll 120 has an end. The bearing 160 is fixed on the orbiting scroll 120 and has a clearance fit with the crankshaft 110. A first oil guide channel 112 is provided in the crankshaft 110. The crankshaft 110 drives the orbiting scroll 120 to move horizontally. The bracket 150 is used to support the orbiting scroll 120. The fixed scroll 130 includes a first disk body 132 and a first volute 134 connected to the first disk body 132. Part of the end surface of the first disk body 132 and the end surface of the first volute 134 are connected to the orbiting scroll 120.
[0091] The orbiting scroll 120 has a second oil guide channel 122 , which is connected to the oil pool of the bearing 160 , and can guide oil to the end surface of the orbiting scroll 120 facing the fixed scroll 130 through the bearing 160 .
[0092] The end surface of the fixed scroll 130 facing the crankshaft 110 has a first oil groove 136 and a second oil groove 138, wherein the first oil groove 136 is irregularly arranged on the surface of the fixed scroll 130, and the first oil groove 136 and the second oil guide channel 122 are intermittently connected to the oil holes formed on the surface of the movable scroll 120, and the connection area between the first oil groove 136 and the second oil guide channel 122 of the movable scroll 120 should be as large as possible, and the second oil groove 138 is arranged on the periphery of the fixed scroll 130, and the second oil groove 138 and the second oil guide channel 122 are intermittently connected to the oil holes formed on the surface of the movable scroll 120, and the connection area between the second oil groove 138 and the second oil guide channel 122 is as small as possible, the second oil groove 138 is connected to the back pressure area on the back of the movable scroll 120, and the first oil groove 136 and the second oil groove 138 are not connected to each other.
[0093] The first oil groove 136 of the fixed scroll 130 guides oil from the second oil guide channel 122 of the orbiting scroll 120 and enters the center of the profile of the first volute 134 .
[0094] The first side wall 1368 of the first groove 1362 of the first oil groove 136 is in a regular arc shape close to the contour line, and the second side wall 1370 away from the contour line has two protrusions. The first side wall 1368 and the second side wall 1370 form a roughly "cat ear shape".
[0095] Furthermore, the fifth groove 1384 of the second oil groove 138 is not directly connected to the second oil guide channel 122, but is intermittently connected to the second oil guide channel 122 through the fourth groove 1382 with a smaller area, and when the orbiting scroll 120 rotates, the connection angle between the fourth groove 1382 and the second oil guide channel 122 is less than or equal to 30°.
