[0058] In the related art, a compression component is provided in the scroll compressor to compress the refrigerant, and the refrigerant discharged from the compression outlet of the compression component is quantitative, which is difficult to meet the demand for changing the displacement of the scroll compressor. In some existing technologies, a capacity regulating valve is provided on the end surface of the fixed scroll, and the capacity regulating valve moves and switches between a sealing position and a release position to change the displacement of the scroll compressor. However, this structural form is difficult to achieve further changes in displacement and cannot meet the various displacement requirements of the scroll compressor.

[0059] Reference below Figure 1-Figure 13 A compression component 1 according to an embodiment of the present invention is described.

[0060] like Figure 1-Figure 13 As shown, the compression component 1 according to the present invention includes: a first scroll 200 and a second scroll 100, wherein the second scroll 100 cooperates with the first scroll 200 to define a compression chamber; wherein a pressure regulating channel 260 is formed on at least one of the first scroll 200 and the second scroll 100, and a pressure regulating inlet 265 and a pressure regulating outlet 266 of the pressure regulating channel 260 are respectively connected to different positions of the compression chamber; and the opening of the pressure regulating channel 260 is adjustable. Specifically, the compression component 1 generally has an inlet suitable for medium to enter and an outlet suitable for medium to be discharged. In order to achieve variable displacement adjustment of the compression component 1, a pressure regulating channel 260 is provided in at least one of the first scroll 200 and the second scroll 100, so that the medium in the compression chamber located in the area where the pressure regulating inlet 265 is located can flow toward the area where the pressure regulating outlet 266 is located through the pressure regulating channel 260, thereby achieving the adjustment of the medium flow discharged by the outlet.

[0061] It is worth mentioning that the adjustable opening of the pressure regulating channel 260 may mean that the flow area of ​​the pressure regulating channel 260, the pressure regulating inlet 265, and the pressure regulating outlet 266 may be adjusted to adjust the opening of the pressure regulating channel 260; or, the adjustable opening of the pressure regulating channel 260 may also mean that the pressure regulating channel 260 may be constructed in multiple parts, the opening timings of different pressure regulating channels 260 may be the same or different, and the openings of different pressure regulating channels 260 may also be the same or different, so as to further adjust the effective displacement of the compression component 1, realize multi-stage variable displacement adjustment of the compression component 1, and meet the multi-displacement requirements of the compression component 1.

[0062] According to the compression component 1 of the present invention, a pressure regulating channel 260 with adjustable opening is set on the first scroll 200 and / or the second scroll 100 to connect different positions of the compression chamber and realize multi-stage variable displacement adjustment of the compression component 1, thereby better matching the cooling capacity requirements of the scroll compressor, improving the energy efficiency of the scroll compressor and reducing costs.

[0063] In some embodiments, the pressure regulating channel 260 is formed inside the first scroll 200 and / or the second scroll 100 , and no additional components are required, so as to achieve variable displacement regulation using the existing structure of the compression component 1 .

[0064] In some embodiments, the first scroll 200 is a fixed scroll, and the second scroll 100 is a movable scroll.

[0065] In some embodiments, since the pressure in the area where the compression component 1 is located at the compression outlet is relatively high, if the distance between the pressure regulating inlet 265 and the compression outlet is too close, the medium with a higher degree of compression will flow back to the area with a lower pressure, which will have a greater impact on the displacement of the compression component 1. Therefore, preferably, the pressure regulating inlet 265 and the compression outlet are spaced apart so that the pressure regulating channel 260 can achieve fine-tuning of the displacement of the compression component 1 without affecting the normal displacement of the compression component 1.

[0066] According to some embodiments of the present invention, a first scroll wheel 200 is provided with a first scroll tooth 210 on its surface, and the first scroll tooth 210 defines a compression channel 240, wherein the compression inlet of the compression channel 240 is connected to the inlet of the compression chamber, and the compression outlet of the compression channel 240 is connected to the outlet of the compression chamber; wherein the pressure regulating inlet 265 is located in the compression channel 240. In some embodiments, the second scroll 100 is spaced apart from the first scroll 200 and a second scroll tooth 110 is provided on the surface of the second scroll 100 facing the first scroll 200, and the second scroll tooth 110 is suitable for moving relative to the first scroll tooth 210 in the compression channel 240 to compress the medium passing through the compression channel 240; wherein a pressure regulating channel 260 is formed on at least one of the first scroll 200 and the second scroll 100, and a pressure regulating inlet 265 of the pressure regulating channel 260 is arranged adjacent to the compression outlet of the compression channel 240, and a pressure regulating outlet 266 of the pressure regulating channel 260 is located between the compression inlet and the pressure regulating inlet 265 of the compression channel 240.

[0067] Here, the second volute 110 meshes with the first volute 210 to achieve compression of the medium. The second volute 110 and the first volute 210 generally extend from the inlet to the outlet of the entire compression component 1. The number of the second volute 110 and the first volute 210 is not limited here. The part of the second scroll 100 and the first scroll 200 adjacent to the inlet is a low-pressure area, and the part adjacent to the outlet 250 is a high-pressure area. The compression channel 240 defined by the first volute 210 also has a compression inlet and a compression outlet. The compression inlet is arranged adjacent to the inlet of the entire compression component 1, and the compression outlet is connected to the outlet of the compression component 1. That is to say, the compression inlet is located in a relatively low-pressure area, and the compression outlet is located in a relatively high-pressure area. At the same time, the compression inlet is located in the compression channel 240, so that the medium in the compression channel 240 can flow toward the area where the pressure regulating outlet 266 in the compression chamber is located through the pressure regulating channel 260, so as to achieve the regulation of the medium flow discharged by the outlet.

[0068] In some embodiments, the compression outlet is the outlet 250 of the compression component 1 .

[0069] According to some embodiments of the present invention, the compression channel 240 is configured as a plurality of compression channels 240 arranged at intervals, and a pressure regulating inlet 265 is provided in at least one compression channel 240. At this time, one compression channel 240 may be provided with one pressure regulating inlet 265, or one compression channel 240 may be provided with a plurality of pressure regulating inlets 265, or a plurality of compression channels 240 may be provided with a pressure regulating inlet 265. The design may be based on actual conditions, so that the setting of the pressure regulating channel 260 can achieve various requirements for the displacement of the compression component 1.

[0070] Of course, it is understandable that one pressure regulating channel 260 may have multiple pressure regulating inlets 265 , and different pressure regulating inlets 265 may be located in different compression channels 240 or in the same compression channel 240 .

[0071] According to some embodiments of the present invention, the pressure regulating channel 260 is configured in multiples, and each compression channel 240 is provided with at least one pressure regulating inlet 265 of the pressure regulating channel 260. Here, at least one pressure regulating inlet 265 may be provided in each compression channel 240, so that each compression channel 240 is connected to at least one pressure regulating channel 260, thereby achieving the regulation of the medium flow in a single compression channel 240.

[0072] According to some embodiments of the present invention, the pressure regulating channel 260 is constructed in multiple configurations, and the medium flow rates of different pressure regulating channels 260 are the same or different. Here, the medium flow rate of the pressure regulating channel 260 can be adjusted by changing the openings of different pressure regulating channels 260, and the openings of different pressure regulating channels 260 can also be the same or different, so that the medium flow rates of different pressure regulating channels 260 are the same or different, so as to further adjust the effective displacement of the compression component 1, realize the multi-stage variable displacement adjustment of the compression component 1, and meet the multi-displacement requirements of the compression component 1.

[0073] In some embodiments, the first volute 210 is configured to be a plurality of first volutes 210 spaced apart in the circumferential direction of the first scroll 200, and a compression channel 240 is defined between adjacent first volutes 210, and a pressure regulating inlet 265 is provided in a region with a higher pressure in each compression channel 240, so that different pressure regulating channels 260 can adjust the medium discharge amount of different compression channels 240. The opening degrees of different compression channels 240 are adjustable, so that the reflux amount of different compression channels 240 is adjustable, and at the same time, the opening timing of different compression channels 240 is controllable, so that the quantitative adjustment of the medium refluxed through the compression channel 240 can be achieved, thereby achieving the quantitative adjustment of the effective displacement of the compression component 1.

[0074] According to some embodiments of the present invention, the pressure regulating outlet 266 is located between the inlet of the compression chamber and the compression inlet. In some embodiments, the pressure regulating inlet 265 of the pressure regulating channel 260 is arranged adjacent to the outlet, while the pressure regulating outlet 266 is arranged adjacent to the inlet. At this time, the pressure in the area where the pressure regulating inlet 265 is located is higher than the pressure in the area where the pressure regulating outlet 266 is located. When the pressure regulating channel 260 is opened, the medium can automatically flow from the pressure regulating inlet 265 through the pressure regulating channel 260 and flow back to the area with lower pressure through the pressure regulating outlet 266. The flow rate of the refluxed medium can be adjusted by changing the opening of the pressure regulating channel 260, thereby changing the flow rate of the medium discharged from the compression outlet, and realizing variable displacement adjustment of the compression component 1.

[0075] Also, the pressure regulating channel 260 can be completely closed, and the medium will not flow back to the area with lower pressure along the pressure regulating channel 260 to ensure the normal displacement of the compression component 1. As the opening of the pressure regulating channel 260 increases, the flow rate of the medium flowing back along the pressure regulating channel 260 increases, and the flow rate of the medium discharged from the compression outlet will decrease, so as to reduce the effective displacement of the compression component 1.

[0076] In some embodiments, Figure 7 As shown, the pressure regulating channel 260 is constructed in multiples, and the multiple pressure regulating channels 260 are arranged at intervals along the circumference of the first scroll 200, and the pressure regulating inlets 265 of the multiple pressure regulating channels 260 are also arranged at intervals along the circumference of the first scroll 200, so that the multiple pressure regulating inlets 265 can be arranged at intervals in the area with higher pressure, so as to disperse and reflux the medium in the area with higher pressure, and avoid the pressure regulating channel 260 having a greater impact on the medium flow. In addition, the opening timing of different pressure regulating channels 260 can be the same or different, so as to further realize the adjustment of the effective displacement of the compression component 1, realize the multi-stage variable displacement adjustment of the compression component 1, and meet the multi-displacement requirements of the compression component 1.

[0077] Furthermore, the positions of different pressure regulating inlets 265 and different pressure regulating outlets 266 can be arranged independently and arbitrarily according to actual needs.

[0078] According to some embodiments of the present invention, Figure 8-Figure 9 As shown, the compression component 1 further includes an adjusting member 300, at least part of which is movably disposed on at least one of the pressure regulating channel 260, the pressure regulating inlet 265, and the pressure regulating outlet 266 to adjust the opening of the pressure regulating channel 260. Specifically, the adjusting member 300 may be disposed on the second scroll 100 and / or the first scroll 200, and at least part of the adjusting member 300 is movably matched with at least one of the pressure regulating channel 260, the pressure regulating inlet 265, and the pressure regulating outlet 266 to adjust the flow area of ​​at least one of the pressure regulating channel 260, the pressure regulating inlet 265, and the pressure regulating outlet 266, thereby adjusting the opening of the pressure regulating channel 260.

[0079] In some embodiments, the regulating member 300 is configured as a solenoid valve, which can drive at least a portion of the solenoid valve to move after acquiring a driving signal to adjust the opening of the pressure regulating channel 260 . The regulating member 300 can also be controlled by other control elements.

[0080] According to some embodiments of the present invention, Figure 8As shown, the compression outlet is located at the radial inner side of the first scroll 200, the compression inlet is located at the radial outer side of the first scroll 200, and the pressure regulating channel 260 extends in the radial direction of the first scroll 200. Specifically, the inlet of the compression component 1 is located at the radial outer side, and the outlet 250 is located at the radial inner side. At this time, the compression inlet of the first scroll 200 is located at the radial outer side, the compression outlet is located at the radial inner side, and the pressure regulating channel 260 extends in the radial direction. At this time, the pressure regulating inlet 265 is located at the radial inner side, and the pressure regulating outlet 266 is located at the radial outer side, so that the pressure regulating channel 260 guides the medium in the higher pressure area to flow back to the higher pressure area.

[0081] According to some embodiments of the present invention, Figure 8 As shown, a pressure regulating channel 260 is provided inside the first scroll 200, and one side surface of the first scroll 200 in the thickness direction is a first surface, and the first surface is provided with a first volute 210 and provided with a pressure regulating inlet 265 and a pressure regulating outlet 266 connected to the pressure regulating channel 260, and at least part of the regulating member 300 is movably provided on the first scroll 200. Specifically, since the second scroll 100 will move when the compression component 1 is working, in order to ensure the connection stability between the regulating member 300 and the compression component 1, the pressure regulating channel 260 is provided inside the first scroll 200 to prevent the regulating member 300 from being separated from the second scroll 100 when the second scroll 100 is working, thereby ensuring the working stability of the compression component 1. The pressure regulating inlet 265 and the pressure regulating outlet 266 of the pressure regulating channel 260 are located on the side surface of the first scroll 200 provided with the first volute 210, so that the pressure regulating inlet 265 and the pressure regulating outlet 266 connect the compression channel 240 with the pressure regulating channel 260.

[0082] Here, the adjusting member 300 can be set at any position on the first scroll 200. The setting position of the adjusting member 300 can be realized so that at least part of the adjusting member 300 can be movably matched with at least one of the pressure regulating channel 260, the pressure regulating inlet 265 and the pressure regulating outlet 266 without affecting the normal operation of the first scroll 200, so that the adjusting member 300 can adjust the flow area of ​​at least one of the pressure regulating channel 260, the pressure regulating inlet 265 and the pressure regulating outlet 266 without affecting the operation of the compression component 1, thereby realizing the adjustment of the opening of the pressure regulating channel 260.

[0083] According to some embodiments of the present invention, a first mounting hole (not shown) is provided on the other side surface of the first scroll 200 in the thickness direction, and the first mounting hole is connected to the pressure regulating channel 260. The adjusting member 300 is movably arranged in the first mounting hole to adjust the flow area of ​​at least one of the pressure regulating channel 260, the pressure regulating inlet 265 and the pressure regulating outlet 266.

[0084] In some embodiments, the first mounting hole is connected to the pressure regulating channel 260 in the thickness direction, and the adjusting member 300 moves in the thickness direction through the first mounting hole to adjust the flow area of ​​the pressure regulating channel 260 .

[0085] According to some embodiments of the present invention, the first mounting hole is opposite to the pressure regulating inlet 265 or the pressure regulating outlet 266 in the thickness direction of the first scroll 200, and the adjusting member 300 moves in the thickness direction through the first mounting hole to adjust the flow area of ​​the pressure regulating inlet 265 or the pressure regulating outlet 266.

[0086] According to some embodiments of the present invention, Figure 6 As shown, the outer peripheral surface of the first scroll 200 in the radial direction is provided with a second mounting hole 216, the second mounting hole 216 is communicated with the pressure regulating channel 260, the adjusting member 300 is movably arranged in the second mounting hole 216, and at least a portion of the adjusting member 300 is suitable for moving along the pressure regulating channel 260 through the second mounting hole 216 to adjust the flow area of ​​the pressure regulating outlet 266. Specifically, the adjusting member 300 is located on the outer peripheral surface of the first scroll 200 in the radial direction. At this time, since the pressure regulating outlet 266 is located in the area of ​​the first scroll 200 with lower pressure, the distance between the pressure regulating outlet 266 and the adjusting member 300 is relatively close, so at least a portion of the adjusting member 300 is movably arranged in the pressure regulating channel 260, and is suitable for adjusting the flow area of ​​the pressure regulating outlet 266.

[0087] It is worth mentioning that when the extension direction of the second mounting hole 216 is consistent with the extension direction of the pressure regulating channel 260, the second mounting hole 216 can be processed on the radial outer peripheral surface of the first scroll 200, and the pressure regulating channel 260 can be processed at the same time. The second mounting hole 216 is opened on the radial outer peripheral surface of the first scroll 200 to facilitate the processing of the pressure regulating channel 260.

[0088] It can be understood that the setting position of the adjusting member 300 is not limited to that described in the above-mentioned embodiments. The adjusting member 300 can also be set at any position on the first scroll 200 so as not to affect the normal operation of the first scroll 200 and at least one of the pressure regulating channel 260, the pressure regulating inlet 265 and the pressure regulating outlet 266, so as to ensure that the adjusting member 300 can adjust the flow area of ​​at least one of the pressure regulating channel 260, the pressure regulating inlet 265 and the pressure regulating outlet 266 without affecting the operation of the compression component 1.

[0089] According to some embodiments of the present invention, Figure 8As shown, the adjusting member 300 includes a driving module 301 and an execution module 302. The driving module 301 is arranged on the first scroll 200 and is suitable for obtaining a driving signal. The execution module 302 is connected to the driving module 301 and is suitable for moving under the drive of the driving module 301 to adjust the opening of the pressure regulating channel 260. Specifically, the adjusting member 300 is constructed as at least one, and the execution module 302 of the adjusting member 300 can extend into the pressure regulating channel 260, and the execution module 302 moves to adjust the opening of the pressure regulating channel 260. The timing of the driving modules 301 of different adjusting members 300 obtaining the driving signal can be the same or different, so as to further realize the adjustment of the effective displacement of the compression component 1, realize the multi-stage variable displacement adjustment of the compression component 1, and meet the multi-displacement requirements of the compression component 1.

[0090] According to some embodiments of the present invention, one of the first scroll 200 and the second scroll 100 is a fixed scroll, and the other of the first scroll 200 and the second scroll 100 is a movable scroll.

[0091] In some embodiments, Figure 1-Figure 4 As shown, the first scroll gear 210 includes a first rack 211, a second rack 212, a third rack 213, and a fourth rack 214. The first rack 211, the second rack 212, the third rack 213, and the fourth rack 214 are respectively developed on the first scroll 200 along the profile line to define a first compression channel 241, a second compression channel 242, a third compression channel 243, and a fourth compression channel 244. The first compression channel 241, the second compression channel 242, the third compression channel 243, and the fourth compression channel 244 respectively accommodate the first movable scroll gear 111, the second movable scroll gear 112, the third movable scroll gear 113, and the fourth movable scroll gear 114 of the second scroll 100. Each compression channel 240 is provided with a compression outlet, and the compression outlet is correspondingly arranged with the outlet 250 of the compression component 1. The tooth heads 215 of multiple racks are connected together to ensure the strength of the first scroll gear 210. The second scroll 110 meshes with the first scroll 210 to form a plurality of compression chambers, and the change in the volume of the compression chambers realizes the suction, compression and exhaust of the scroll compressor. The multi-tooth scroll assembly has the advantage of smaller torque fluctuation during operation.

[0092] In some embodiments, the outlet 250 of the compression component 1 is located on the surface of the first scroll 200 and is disposed through it.

[0093] In some embodiments, Figure 5 As shown, a pressure regulating channel 260 is provided inside the first scroll 200, and the pressure regulating channel 260 connects the area with higher pressure and the area with lower pressure, and the on-off of the pressure regulating channel 260 is controlled by the solenoid valve to achieve displacement adjustment of the scroll compressor, and the structure is simple. The solenoid valve is provided on the first scroll 200, and the space arrangement is convenient.

[0094] In some embodiments, Figure 10-13 As shown, an exhaust valve plate 400 is also provided on the side of the first scroll 200 away from the first volute 210. The exhaust valve plate 400 can selectively close the outlet 250 of the compression component 1 to ensure the exhaust pressure and check the return. Here, the exhaust valve plate 400 is constructed to correspond to the compression outlets one by one, and includes a first exhaust valve plate 401, a second exhaust valve plate 402, a third exhaust valve plate 403, and a fourth exhaust valve plate 404. The first outlet 251, the second outlet 252, the third outlet 253, and the fourth outlet 254 are provided on the back of the first scroll 200. The first outlet 251, the second outlet 252, the third outlet 253, and the fourth outlet 254 are provided at the compression end position of the first compression channel 241, the second compression channel 242, the third compression channel 243, and the fourth compression channel 244. The first exhaust valve plate 401 , the second exhaust valve plate 402 , the third exhaust valve plate 403 , and the fourth exhaust valve plate 404 are exhaust valve plates 400 that are opened and closed independently of each other, and correspond to the first outlet 251 , the second outlet 252 , the third outlet 253 , and the fourth outlet 254 one by one.

[0095] In some embodiments, Figure 7 As shown, the pressure regulating channel 260 is constructed as a plurality of pressure regulating channels 261, a second pressure regulating channel 262, a third pressure regulating channel 263, and a fourth pressure regulating channel 264. The regulating member 300 is also constructed as a plurality of pressure regulating channels 260 corresponding to each other, and includes a first solenoid valve 310, a second solenoid valve 320, a third solenoid valve 330, and a fourth solenoid valve 340. The first solenoid valve 310, the second solenoid valve 320, the third solenoid valve 330, and the fourth solenoid valve 340 are arranged on the first scroll 200. Each solenoid valve is composed of a driving module 301 and an execution module 302. The driving module 301 controls the execution module 302 to perform linear motion to realize the opening and closing of the solenoid valve. The multi-stage variable displacement adjustment of the scroll compressor is realized by controlling the opening and closing of the solenoid valve. The first solenoid valve 310, the second solenoid valve 320, the third solenoid valve 330, and the fourth solenoid valve 340 are independently controlled to open and close. When 0 to 4 solenoid valves are opened, the corresponding 0 to 4 compression channels 240 are connected to the corresponding pressure regulating channels 260, and the effective displacement decreases, thereby realizing multi-stage regulation of the total displacement of the scroll compressor.

[0096] Here, for example, the initial effective displacement of the four compression channels 240 is V0. After the compression channel 240 is connected with the corresponding pressure regulating channel 260, the effective displacement of the first compression channel 241, the second compression channel 242, the third compression channel 243, and the fourth compression channel 244 becomes V1, V2, V3, and V4, respectively.

[0097] When all four solenoid valves are closed, there is no medium reflux in all compression passages 240, and the total displacement of the scroll compressor is 4V0;

[0098] When one solenoid valve is open and three solenoid valves are closed, one of the four compression passages 240 has medium reflux, and the total displacement of the scroll compressor has four situations, namely 3V0+V1, 3V0+V2, 3V0+V2, and 3V0+V4;

[0099] When two solenoid valves are opened and two solenoid valves are closed, two of the four compression passages 240 have medium reflux, and the total displacement of the scroll compressor has six cases, namely, 2V0+V1+V2, 2V0+V1+V3, 2V0+V1+V4, 2V0+V2+V3, 2V0+V2+V4, 2V0+V3+V4;

[0100] When three solenoid valves are opened and one solenoid valve is closed, three of the four compression passages 240 have medium reflux, and the total displacement of the scroll compressor has four situations, namely V0+V1+V2+V3, V0+V1+V2+V4, V0+V1+V3+V4, and V0+V2+V3+V4;

[0101] When all four solenoid valves are opened, medium refluxes through all compression passages 240 , and the total displacement of the scroll compressor is V1+V2+V3+V4.

[0102] In summary, for Figure 1 The compression component 1 in the illustrated embodiment can achieve at least 16 levels of variable displacement regulation through an independently arranged pressure regulating channel 260 and a corresponding solenoid valve.
