For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] Hereinafter, a compressor 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0051] like Figure 1-Figure 10 As shown, a compressor 100 according to an embodiment of the present invention includes: a motor assembly 1 and a compression assembly 2, the motor assembly 1 includes a crankshaft 12, the crankshaft 12 includes at least two driving parts 121 spaced apart along the axial direction, and two adjacent driving parts 121 are arranged at intervals along the circumferential direction of the crankshaft 12; the compression assembly 2 includes at least two moving plates 21, the crankshaft 12 is axially penetrated in the compression assembly 2, at least two moving plates 21 are connected one by one with at least two driving parts 121, and a compression chamber 24 is defined between two adjacent moving plates 21.

[0052] Thereby, the refrigerant compression efficiency of the compression chamber 24 can be improved, and the radial dimension of the compression assembly 2 along the crankshaft 12 can be made smaller, which is conducive to the miniaturization design of the compressor 100 and improves the practicability of the compressor 100.

[0053] First, if Figure 1-Figure 2As shown, the compressor 100 includes a motor assembly 1 and a compression assembly 2. The motor assembly 1 includes a motor 11 and a crankshaft 12, wherein the motor 11 is connected to the crankshaft 12 and is used to drive the crankshaft 12 to rotate around its own axis. The crankshaft 12 includes at least two driving parts 121, which are arranged spaced apart along the axial direction of the crankshaft 12, and the driving parts 121 are arranged to protrude outward along the radial direction of the crankshaft 12, and two adjacent driving parts 121 are arranged spaced apart along the circumferential direction of the crankshaft 12.

[0054] The compression assembly 2 includes at least two moving plates 21, which are arranged in sequence along the axial direction of the crankshaft 12. The crankshaft 12 is axially inserted into the compression assembly 2. The at least two moving plates 21 correspond to and are connected to at least two driving parts 121 one by one. The crankshaft 12 is used to drive the multiple moving plates 21 to eccentrically rotate through the multiple driving parts 121.

[0055] Specifically, two adjacent driving parts 121 may be arranged at opposite sides of the crankshaft 12 in the radial direction, so that the rotation angles of two adjacent moving plates 21 always differ by 180°, thereby ensuring that the compression chamber 24 can effectively achieve compression.

[0056] Specifically, when the compressor 100 is started, the motor 11 can drive the crankshaft 12 to rotate around its own axis, and the driving part 121 can rotate with the crankshaft 12 to drive the corresponding moving plate 21 to rotate eccentrically, and the compression chamber 24 constantly changes. The compression chamber 24 can suck in the refrigerant and compress it, and then discharge the compressed refrigerant to the outside.

[0057] Through the above arrangement, compared with the arrangement of the fixed scroll and the movable scroll, the compression chamber 24 defined by the double movable disks 21 has a higher refrigerant compression efficiency, and the movement range of a single movable disk 21 is smaller, which can make the radial dimension of the compression assembly 2 along the crankshaft 12 smaller, which is conducive to the miniaturization design of the compressor 100. In addition, since the two movable disks 21 are driven by the same crankshaft 12, the force exerted by the movable disks 21 on the crankshaft 12 can be partially offset, which is conducive to improving the running stability of the crankshaft 12.

[0058] According to the compressor 100 of the embodiment of the present invention, the compression chamber 24 is defined by two moving plates 21, so that the refrigerant compression efficiency of the compression chamber 24 can be improved, and the radial dimension of the compression component 2 along the crankshaft 12 can be made smaller, which is conducive to the miniaturization design of the compressor 100 and improves the practicability of the compressor 100.

[0059] In some embodiments of the present invention, Figure 3-Figure 6As shown, there are multiple moving disks 21, and any three moving disks 21 include an end moving disk 22 and an intermediate moving disk 23. The end moving disk 22 is located at the end position of the multiple moving disks 21, and the intermediate moving disk 23 is located at the middle position of the multiple moving disks 21, and the two sides of the intermediate moving disk 23 can respectively define a compression chamber 24 with the adjacent moving disks 21.

[0060] Exemplarily, the number of movable disks 21 can be three, and the three movable disks 21 include two end movable disks 22 and one middle movable disk 23. The end movable disks 22, the middle movable disk 23 and the end movable disks 22 are arranged in sequence, and the two sides of the middle movable disk 23 can respectively cooperate with the two end movable disks 22 to define two compression chambers 24; or, the number of movable disks 21 can be four, and the four movable disks 21 include two end movable disks 22 and two middle movable disks 23. The end movable disks 22, the middle movable disk 23, the middle movable disk 23 and the end movable disks 22 are arranged in sequence, and the two sides of the middle movable disk 23 can respectively cooperate with the adjacent movable disks 21 to define three compression chambers 24.

[0061] It should be noted that one of the two end moving disks 22 is provided with an exhaust hole 221 and the other is not provided with an exhaust hole 221 , and the end moving disk 22 provided with the exhaust hole 221 is located at the most downstream in the flow direction of the refrigerant.

[0062] Through the above arrangement, the space of the compressor 100 can be fully utilized, which is conducive to arranging more compression chambers 24, thereby improving the refrigerant compression effect of the compressor 100.

[0063] Of course, the present invention is not limited thereto, and the movable disc 21 may be divided into multiple groups, and the multiple groups of movable discs 21 are sequentially arranged along the axial direction of the crankshaft 12, and the two movable discs 21 in each group jointly define the compression chamber 24. In this way, the structure of the movable disc 21 can be simplified, which is conducive to reducing the processing difficulty of the compressor 100.

[0064] In some embodiments of the present invention, Figure 3 As shown, an upper-stage air outlet end of at least two compression chambers 24 is communicated with a lower-stage air inlet end of another compression chamber 24 to define multi-stage compression.

[0065] Exemplarily, the compression assembly 2 may include an end movable disc 22, an intermediate movable disc 23, and another end movable disc 22 arranged in sequence, the end movable disc 22 cooperates with the intermediate movable disc 23 to define a first compression chamber 241, the intermediate movable disc 23 cooperates with the other end movable disc 22 to define a second compression chamber 242, the first compression chamber 241 is located upstream of the second compression chamber 242, the air outlet end 244 of the first compression chamber 241 is formed as an upper air outlet end, the air inlet end 243 of the second compression chamber 242 is formed as a lower air inlet end, and the upper air outlet end of the first compression chamber 241 is connected to the lower air inlet end of the second compression chamber 242 to form a two-stage compression. In this way, the refrigerant compression effect of the compressor 100 can be guaranteed.

[0066] In some embodiments of the present invention, Figure 6-Figure 7 As shown, a flow passage 231 can be provided in the middle moving disk 23, and the flow passage 231 is connected to the upper air outlet and the lower air inlet, respectively. Through the above arrangement, the flow path of the refrigerant can be shortened, and the flow process of the refrigerant can be made more stable, thereby improving the compression effect of the compression assembly 2.

[0067] Of course, the present invention is not limited thereto, and a connecting pipe may be provided on the inner wall of the housing assembly 3, and the connecting pipe may connect the upper gas outlet and the lower gas inlet, thereby meeting different working conditions.

[0068] In some embodiments of the present invention, Figure 6-Figure 7 As shown, a flow channel 231 can be set to extend radially along the intermediate moving disk 23, and a lower-stage air inlet end is provided at the radial inner end of the flow channel 231 along the intermediate moving disk 23, and an upper-stage air outlet end is provided at the radial outer end of the flow channel 231 along the intermediate moving disk 23.

[0069] It can be understood that the air inlet end 243 of the compression chamber 24 is usually located at the edge of the movable disk 21 and the air outlet end 244 is located in the middle part of the movable disk 21. By setting the flow channel 231 to extend radially along the middle movable disk 23, the flow channel 231 can directly introduce the refrigerant discharged from the compression chamber 24 located upstream into the compression chamber 24 located downstream, which is beneficial to simplify the structure of the compression assembly 2.

[0070] In some embodiments of the present invention, Figure 3 As shown, the compressor 100 of the embodiment of the present invention further includes a housing assembly 3, the compression assembly 2 is arranged in the housing assembly 3, and a first stopper is arranged in the housing assembly 3, and the first stopper is used to cooperate with the intermediate moving plate 23 to limit the rotational freedom of the intermediate moving plate 23. Through the above arrangement, the self-rotation of the intermediate moving plate 23 can be limited, which is conducive to improving the operating stability of the compressor 100.

[0071] In some embodiments of the present invention, Figure 3 and Figure 8 As shown, the first limiting member can be constructed as a limiting ring 4, which is sleeved on the outer peripheral wall of the intermediate movable plate 23. A limiting pin 232 is provided at the edge of the intermediate movable plate 23, and the limiting pin 232 extends along the axial direction of the crankshaft 12. The limiting ring 4 is provided with a limiting pin ring 41 protruding inwardly, and the limiting pin ring 41 is used to be sleeved on the outer side of the limiting pin 232 and to cooperate with the limiting pin 232 in a limiting manner, so that the limiting pin ring 41 can limit the rotation of the intermediate movable plate 23 around its own axis through the limiting pin 232.

[0072] Through the above arrangement, the limiting effect of the limiting ring 4 can be ensured, the operating stability of the intermediate moving plate 23 is improved, and the limiting ring 4 is easy to arrange, which can reduce the difficulty of assembling the compressor 100.

[0074] Through the above arrangement, the matching reliability between the limiting ring 4 and the intermediate movable plate 23 can be improved, which is beneficial to improving the limiting effect of the limiting ring 4 on the intermediate movable plate 23 and improving the overall stability of the compressor 100.

[0075] In some embodiments of the present invention, Figure 4 , Figure 6 and Fig. 9 As shown, at least two moving disks 21 are multi-tooth moving disks, and the multi-tooth moving disks include a disk body 211 and a plurality of volutes 212. At least one side of the disk body 211 is provided with a plurality of volutes 212, and the plurality of volutes 212 located on the same side are arranged spaced apart along the circumference of the disk body 211. The plurality of volutes 212 on the same side of the multi-tooth moving disk cooperate with the plurality of volutes 212 of the adjacent multi-tooth moving disk to define a plurality of compression chambers 24. Each compression chamber 24 is provided with an outlet end 244 and an inlet end 243, and the refrigerant can flow into the corresponding compression chamber 24 from the inlet end 243 and be discharged from the outlet end 244 after compression.

[0076] Specifically, the number of the volute teeth 212 located on the same side of the multi-tooth moving plate can be 2-10, such as 2, 3, 4, 5, etc.

[0077] Through the above arrangement, at different positions of the moving disk 21 along the circumferential direction, a plurality of compression chambers 24 can respectively compress the refrigerant, and the gas torque of the compressor 100 is relatively uniform, which can improve the operating stability of the compression assembly 2.

[0078] In some embodiments of the present invention, Figure 3 As shown, the number of multi-toothed movable discs can be multiple, and any two adjacent multi-toothed movable discs cooperate to define multiple compression chambers 24. Through the above arrangement, the operating stability of the compression assembly 2 can be further improved, and the reliability of the compressor 100 can be improved.

[0079] In some embodiments of the present invention, Figure 3 and Figure 7As shown, the middle multi-toothed movable disk among any three multi-toothed movable disks may be provided with a plurality of flow passages 231 , and each flow passage 231 is used to connect two compression chambers 24 arranged along the axial direction of the crankshaft 12 .

[0080] Exemplarily, the compression assembly 2 may be provided with three multi-toothed movable disks, which are arranged in sequence along the axial direction of the crankshaft 12. The multi-toothed movable disk at one end and the multi-toothed movable disk in the middle define a plurality of first compression chambers 241, and the multi-toothed movable disk at the other end cooperates with the multi-toothed movable disk in the middle to define a plurality of second compression chambers 242, and the plurality of first compression chambers 241 and the plurality of second compression chambers 242 correspond one to one along the axial direction of the crankshaft 12. The first compression chamber 241 is located upstream of the second compression chamber 242, and the multi-toothed movable disk in the middle is provided with a plurality of flow passages 231, and the plurality of flow passages 231 are arranged at intervals along the circumference of the multi-toothed movable disk, and the plurality of flow passages 231 are used to respectively connect the plurality of first compression chambers 241 with the corresponding second compression chambers 242 to form a secondary compression.

[0081] Through the above arrangement, the flow path of the refrigerant can be shortened, the flow stability of the refrigerant can be improved, and the compression effect of the compressor 100 on the refrigerant can be ensured.
