Description

Technical Field

[0001] This utility model relates to the technical field of air conditioners, and in particular to a compressor and an air conditioner having the same. Background Technology

[0002] Rotary compressors are currently mainly used in residential air conditioning systems. They act as power units to circulate refrigerant through pipelines to meet cooling or heating needs. The compressor in this technology includes an upper cylinder, a lower cylinder, and a crankshaft. The crankshaft has a first roller and a second roller, located in the upper and lower cylinders respectively, allowing for alternating intake of refrigerant during compressor operation. To reduce manufacturing costs, the compressor in this technology supplies refrigerant to the upper cylinder through an intake channel. The lower cylinder is connected to a distribution channel, which is also connected to the intake channel, allowing a portion of the refrigerant in the intake channel to flow into the distribution channel and then supply refrigerant to the lower cylinder. However, in this technology, the lower cylinder has a lower intake volume compared to the upper cylinder during operation, resulting in reduced output stability of the compressor.

[0055] The compressor 10 for an air conditioner 20 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0056] like Figures 1-10 As shown, the compressor 10 for the air conditioner 20 in this embodiment of the present invention includes a first compression chamber 110, an air intake channel 200, a second compression chamber 310, and a flow distribution channel 400.

[0057] The intake passage 200 includes a first intake section 210, the flow area of ​​which is the minimum flow area of ​​the intake passage 200. The first intake section 210 is directly connected to the first compression chamber 110. Alternatively, the first intake section 210 is connected to the first compression chamber 110 through an intake structure. One end of the diversion passage 400 is disposed on the peripheral wall of the first intake section 210 of the intake passage 200, and the other end communicates with the second compression chamber 310. The flow area of ​​the first intake section 210 is larger than the minimum flow area of ​​the diversion passage 400.

[0058] Refrigerant enters the compressor 10 through the inlet of the intake passage 200. When the first intake section 210 is directly connected to the first compression chamber 110, a portion of the refrigerant in the intake passage 200 flows along the extension direction of the intake passage 200 and flows into the first compression chamber 110 through the outlet of the first intake section 210. When the first intake section 210 is connected to the first compression chamber 110 through an intake structure, a portion of the refrigerant in the intake passage 200 sequentially enters the first compression chamber 110 through the first intake section 210 and the intake structure.

[0059] Another portion of the refrigerant in the intake passage 200 enters the split passage 400 through that end when it flows through one end of the split passage 400, and then flows into the second compression chamber 310 through the other end of the split passage 400.

[0060] Compared with related technologies, the compressor 10 for an air conditioner 20 in this embodiment includes a first compression chamber 110 and a second compression chamber 310. The first compression chamber 110 is directly or indirectly connected to the intake channel 200, and the second compression chamber 310 is connected to the intake channel 200 through a diversion channel 400. The flow area of ​​the first intake section 210 of the intake channel 200 is the minimum flow area of ​​the intake channel 200. One end of the diversion channel 400 is disposed on the peripheral wall of the first intake section 210 of the intake channel 200, and the flow area of ​​the first intake section 210 is larger than the minimum flow area of ​​the diversion channel 400. This improves the structure of the intake channel 200 and the diversion channel 400, making the intake of the first compression chamber 110 and the second compression chamber 310 more uniform, thus improving the output stability of the compressor 10 in this embodiment.

[0061] In some embodiments, such as Figure 2 As shown, the diversion channel 400 includes a first channel segment 410, a second channel segment 420, and a third channel segment 430.

[0062] One end of the first channel section 410 is disposed on the peripheral wall of the intake channel 200. Along the gas flow direction, the cross-sectional area of ​​the first channel section 410 gradually decreases. Alternatively, along the gas flow direction, the cross-sectional area of ​​the first channel section 410 first gradually decreases and then remains constant. This increases the intake volume of the diversion channel 400 and also allows the refrigerant flow in the intake channel 200 to flow more smoothly into the first channel section 410, reducing the resistance of the diversion channel 400 to the refrigerant flow, thus further increasing the intake volume of the second compression chamber 310.

[0063] The second channel section 420 is connected to the first channel section 410, and its cross-sectional area is equal along the gas flow direction. The third channel section 430 is a groove formed on the peripheral wall of the second compression chamber 310, and its cross-sectional area gradually decreases along the gas flow direction. That is, the extension direction of the third channel section 430 gradually slopes towards the second compression chamber 310, so as to promote the smooth flow of refrigerant in the third channel section 430 towards the second compression chamber 310, greatly reducing the flow resistance of the refrigerant in the third channel section 430.

[0064] Specifically, such as Figure 1As shown, the compressor 10 of this embodiment further includes a first cylinder body 100, a partition, and a second cylinder body 300. The first cylinder body 100 defines a first compression chamber 110, an intake passage 200 is disposed on the first cylinder body 100, and a first passage section 410 is disposed on the first cylinder body 100. The partition is disposed on one side of the first cylinder body 100, and a second passage section 420 is disposed on the partition. The second cylinder body 300 is disposed on the side of the partition facing away from the first cylinder body 100. The second cylinder body 300 defines a second compression chamber 310, and a third passage section 430 is disposed on the second cylinder body 300 and penetrates the end face of the second cylinder body 300 facing the partition. Thus, the intake passage 200 and the third passage section 430 are directly machined on the first cylinder block 100, the second passage section 420 is machined on the second cylinder block 300, and the first passage section 410 is machined on the second cylinder block 300, which reduces the structural redundancy of the compressor 10 in this embodiment and lowers the manufacturing cost.

[0065] In some embodiments, the compressor 10 of this utility model further includes a crankshaft 600, which has two rollers 610. One roller 610 is disposed in the first compression chamber 110, and the other roller 610 is disposed in the second compression chamber 310. Specifically, the first cylinder body 100, the partition plate, and the second cylinder body 300 are respectively provided with through holes for the crankshaft 600 to mate with, so that the crankshaft 600 is installed between the first cylinder body 100, the partition plate, and the second cylinder body 300. When the crankshaft 600 rotates, it drives the two rollers 610 to rotate in the first compression chamber 110 and the second compression chamber 310 respectively, so as to realize the alternating intake of air in the first compression chamber 110 and the second compression chamber 310.

[0066] Furthermore, the flow area S1 of the first intake section 210 is:

[0067] S1 = π·[(V1-aV2) / 2] 2 In the formula, the value of a ranges from 1 to 3.7.

[0068] Wherein, V1 is the volume of the larger of the first compression chamber 110 and the second compression chamber 310; V2 is the volume of the roller 610 corresponding to the larger of the first compression chamber 110 and the second compression chamber 310. Thus, determining the flow area of ​​the first intake section 210 based on the working volume of either the first compression chamber 110 or the second compression chamber 310 (the larger of the two) of the compressor 10 not only ensures that the first intake section 210 has a sufficiently large flow area to provide adequate refrigerant to the first compression chamber 110 and the second compression chamber 310, but also avoids the first intake section 210 from being too large, thereby reducing structural redundancy and helping to reduce the overall size of the compressor 10.

[0069] It should be noted that the specific value of 'a' needs to be determined according to the corresponding roller 610 specifications. That is, the value of 'a' includes, but is not limited to, 1, 1.2, 1.4, 1.7, 2.1, 2.3, 2.5, 2.8, 3, 3.4, or 3.7. For example, when the corresponding roller 610 has a diameter of 30mm and a thickness of 10mm, the value of 'a' is 1.13. As another example, when the corresponding roller 610 has a diameter of 50mm and a thickness of 10mm, the value of 'a' is 1.15. And as yet another example, when the corresponding roller 610 has a diameter of 40mm and a thickness of 10mm, the value of 'a' is 1.33.

[0070] In some embodiments, such as Figure 5 As shown, the intake structure is a through-hole 240, one end of which is connected to one end of the first intake section 210, and the other end of which is connected to the first compression chamber 110. The diameter of the through-hole 240 is smaller than the diameter of the first intake section 210. The intake channel 200 also includes a third intake section 230, the other end of which is connected to the third intake section 230. The diameter of the third intake section 230 is larger than the diameter of the first intake section 210. That is, the refrigerant enters the first compression chamber 110 sequentially through the second intake section 220, the first intake section 210, and the through-hole 240. Because the diameter of the second intake section 220 is larger than that of the first intake section 210, the large pressure drop loss caused by excessive refrigerant flow rate is reduced when the refrigerant flows into the second intake section 220.

[0071] In some embodiments, such as Figure 4 As shown, the intake passage 200 also includes a second intake section 220. One end of the first intake section 210 is connected to the first compression chamber 110, and the other end of the first intake section 210 is connected to the second intake section 220. The diameter of the second intake section 220 is larger than the diameter of the first intake section 210. That is, the refrigerant enters the first compression chamber 110 sequentially through the second intake section 220 and the first intake section 210. Because the diameter of the second intake section 220 is larger than the diameter of the first intake section 210, excessive refrigerant flow velocity during refrigerant inflow into the second intake section 220 can be avoided, preventing significant pressure drop losses. Furthermore, since the intake passage 200 only includes the first intake section 210 and the second intake section 220, the overall size of the intake passage 200 is relatively short, which is suitable for situations where the ratio of the diameter of the first cylinder block 100 to the diameter of the first compression chamber 110 is small, thus helping to reduce the overall size of the compressor 10.

[0072] In some embodiments, the minimum flow area of ​​the diversion channel 400 is located in the third channel section 430. This allows the first channel section 410 and the second channel section 420 to have a larger air intake volume, and allows for a smooth transition between the first channel section 410, the second channel section 420 and the third channel section 430, thereby reducing the resistance of the diversion channel 400 to the refrigerant airflow.

[0073] Optionally, the ratio of the flow area of ​​the first intake section 210 to the minimum flow area of ​​the diversion channel 400 is 1.1-8. Optionally, the ratio of the flow area of ​​the first intake section 210 to the minimum flow area of ​​the diversion channel 400 is 2.8-7.7. Optionally, the ratio of the flow area of ​​the first intake section 210 to the minimum flow area of ​​the diversion channel 400 is 4.5-6.1. This ensures that the flow area of ​​the first intake section 210 is greater than the minimum flow area of ​​the diversion channel 400 while avoiding an excessively large flow area of ​​the first intake section 210, which helps to reduce the overall size of the compressor 10 in this embodiment and lower manufacturing costs.

[0074] The ratio of the flow area of ​​the first air intake section 210 to the minimum flow area of ​​the diversion channel 400 is, but is not limited to, 1.1, 2.3, 2.7, 3.5, 4.5, 5.1, 5.9, 6.1, 7.2, 7.7 or 8.

[0075] In some embodiments, such as Figure 4 As shown, the first channel section 410 is defined by the overlapping of the first hole 411 and the second hole 412. Because the inlet of the diversion channel is larger than the outlet of the first channel section 410, the air intake of the diversion channel is increased. This also allows the refrigerant airflow in the intake channel 200 to flow more smoothly into the first channel section 410, reducing the resistance of the diversion channel 400 to the refrigerant airflow. This, in turn, increases the air intake of the second compression chamber 310, reduces the performance difference between the first compression chamber 110 and the second compression chamber 310, and improves the output stability of the compressor 10. Furthermore, the structure where the inlet of the diversion channel is larger than the outlet of the first channel section 410 is naturally formed by the overlapping of multiple holes, greatly reducing the processing difficulty of the first channel section 410.

[0076] Furthermore, such as Figure 5As shown, the axes of the first hole 411, the second hole 412, and the intake channel 200 are on the same plane; the axes of the first hole 411 and the second hole 412 are intersecting. The axis of the first hole 411 is perpendicular to the axis of the intake channel 200; the axis of the second hole 412 intersects the axis of the intake channel 200; along the gas flow direction, the axis of the second hole 412 is inclined towards the first compression chamber 110, and the second hole 412 is located on the side of the first hole 411 facing the first compression chamber 110. Since the axes of multiple holes intersect at the same point, the refrigerant airflow flowing into the first channel section 410 from the intake channel 200 is fully mixed at the intersection of multiple holes, thereby avoiding excessively high local flow velocity or eddy current generation in the diversion channel 400, which is conducive to the refrigerant entering the second compression chamber 310 more smoothly.

[0077] Specifically, the multiple holes include a first hole 411 and a second hole 412. The axis of the first hole 411 and the axis of the intake channel 200 are on the same plane and are perpendicular to the axis of the intake channel 200. The axis of the second hole 412 intersects the axis of the intake channel 200 and is on the same plane. Along the gas flow direction, the axis of the second hole 412 is inclined towards the first compression chamber 110. That is, the axes of the first hole 411 and the second hole 412 intersect at the same point, which can avoid excessively high local flow velocity or eddy currents in the diversion channel 400 and reduce the resistance of the diversion channel 400 to the refrigerant. Furthermore, by processing the first hole 411 and the second hole 412, the first channel section 410 naturally forms a structure where the inlet is larger than the outlet, reducing the number of processing steps required to form the first channel section 410 and lowering the processing difficulty, thus reducing manufacturing costs.

[0078] For example Figure 6 As shown, multiple holes are arranged in pairs. One hole extends vertically, with its axis represented by a vertically extending dashed line. The other hole is inclined, with its axis represented by a dashed line extending in the inclined direction.

[0079] It should be noted that the number of holes is not limited to two; there can be three, four, five, or other numbers. At least one of the holes is inclined so that the inlet of the diversion channel formed by the multiple holes is larger than the outlet.

[0080] In some embodiments, such as Figure 4 and Figure 5As shown, the diameter of the first hole 411 is equal to the diameter of the second hole 412. That is, when machining the first channel segment 410, the tool (e.g., a drill bit) used to machine the first hole 411 and the second hole 412 has the same size specifications. Therefore, the same tool can be used to machine the first hole 411 and the second hole 412, eliminating the need to change tools and thus further improving machining efficiency.

[0081] The angle between the axis of the second hole 412 and the axis of the intake passage 200 is 50° to 70°. Optionally, the angle between the axis of the second hole 412 and the axis of the intake passage 200 is 52° to 66°. Optionally, the angle between the axis of the second hole 412 and the axis of the intake passage 200 is 52° to 66°. Optionally, the angle between the axis of the second hole 412 and the axis of the intake passage 200 is 58° to 60°. This avoids the angle between the axis of the second hole 412 and the axis of the intake passage 200 being too large, reducing manufacturing difficulty.

[0082] The angle between the axis of the second hole 412 and the axis of the intake channel 200 includes, but is not limited to, 50°, 52°, 54°, 59°, 60°, 62°, 66°, 67° or 70°.

[0083] For example Figure 5 As shown, the diameter of the first hole 411 and the second hole 412 is L2, and the angle between the axis of the second hole 412 and the horizontal plane is a. Then the length L1 of the outlet of the first channel section 410 is L2 / sina.

[0084] In some embodiments, such as Figure 7 As shown, the cross-section of the second channel section 420 is circular, and the axis of the second channel section 420 is coaxial with the axis of the second hole 412. The diameter of the second channel section 420 is greater than or equal to the diameter of the second hole 412. Because the axis of the second channel section 420 is parallel to or coincides with the axis of the second hole 412, the refrigerant airflow in the first channel section 410 can flow smoothly into the second channel section 420, thereby reducing the resistance to the refrigerant airflow and improving the intake volume of the second compression chamber 310.

[0085] In some embodiments, such as Figure 1 As shown, the partition 500 is disposed on one side of the first cylinder body 100, and the partition 500 contacts and abuts against the corresponding end face of the first cylinder body 100. The part of the corresponding end face of the first cylinder body 100 that is in complete contact with the partition 500 is a sealed area, thereby preventing air leakage between the first cylinder body 100 and the partition 500.

[0086] Specifically, the partition 500 and the first cylinder body 100 are fastened together by screws, so that the corresponding end face of the first cylinder body 100 is in close contact with the part of the partition 500.

[0087] The distance between the opening edge of the first channel segment 410 on the corresponding end face of the first cylinder block 100 and the inner edge of the sealing area is greater than or equal to 1 mm. For example Figure 6 As shown, the distance between the opening edge of the first channel segment 410 on the corresponding end face of the first cylinder body 100 and the inner edge of the sealing area is L4. The distance between the opening edge of the first channel segment 410 on the corresponding end face of the first cylinder body 100 and the inner edge of the sealing area includes, but is not limited to, 1mm, 2mm, and 3mm.

[0088] The distance between the opening edge of the first channel segment 410 on the corresponding end face of the first cylinder block 100 and the outer edge of the sealing area is greater than or equal to 1 mm. For example Figure 6 As shown, the distance between the opening edge of the first channel segment 410 on the corresponding end face of the first cylinder body 100 and the outer edge of the sealing area is L3. The distance between the opening edge of the first channel segment 410 on the corresponding end face of the first cylinder body 100 and the outer edge of the sealing area includes, but is not limited to, 1mm, 2.2mm, and 3.3mm.

[0089] In other words, the distance between the opening edge of the first channel section 410 on the corresponding end face of the first cylinder body 100 and the outer or inner edge of the sealing area is at least 1 mm, thereby ensuring that there is a sufficiently large sealing area between the first cylinder body 100 and the partition 500, and ensuring that there is no air leakage between the first cylinder body 100 and the partition 500.

[0090] In some embodiments, such as Figure 8 As shown, the third channel segment 430 is a groove provided on the peripheral wall of the second compression chamber 310. That is to say, the wall surface of the groove directly forms the third channel segment 430, which increases the flow area of ​​the refrigerant, thereby helping to increase the intake volume of the second compression chamber 310. Furthermore, the third channel segment 430 is formed by directly slotting on the peripheral wall of the second compression chamber 310, which reduces the manufacturing difficulty.

[0091] In some embodiments, such as Figure 10As shown, the third channel section 430 includes a first groove section and a second groove section connected in sequence. Along the gas flow direction, the axes of both the first and second groove sections are inclined towards the second compression chamber 310. Because the axes of the first section 431 and the second section 434 are both inclined towards the second compression chamber 310, the refrigerant entering the third channel section 430 can gradually and smoothly flow towards the second compression chamber 310. Furthermore, the inclination angle of the axis of the second groove section is greater than that of the axis of the first groove section. That is, the degree to which the second section 434 is inclined towards the second compression chamber 310 is greater than the degree to which the first section 431 is inclined towards the second compression chamber 310.

[0092] In some implementations, such as Figure 10 As shown, the inclination angle of the axis of the second groove section is greater than the inclination angle of the axis of the second hole 412 towards the first compression chamber 110. The inclination angle of the axis of the second hole 412 towards the first compression chamber 110 is also greater than the inclination angle of the axis of the first groove section. In other words, the refrigerant in the third channel section 430 is guided sequentially by the first section 431 and the second section 434, gradually flowing smoothly towards the second compression chamber 310, greatly reducing the flow resistance of the refrigerant in the third channel section 430, thereby reducing the performance difference between the first compression chamber 110 and the second compression chamber 310. Especially when the first compression chamber 110 and the second compression chamber 310 operate alternately, the output stability of the compressor 10 is improved.

[0093] Furthermore, the tilt angle of the axis of the second section 434 is greater than that of the axis of the first section 431, which allows the third channel section 430 to bend at a larger angle. This eliminates the need for the second cylinder body 300 to have a large vertical dimension to accommodate the third channel section 430, thereby reducing the overall size of the compressor 10 in this embodiment and lowering manufacturing costs.

[0094] In some embodiments, the distance between the outlet of the third channel section 430 and the end face of the peripheral wall of the second compression chamber 310 away from the first compression chamber 110 is within 2 mm. That is, the outlet of the third channel section 430 is brought as close as possible to the end face of the peripheral wall of the second compression chamber 310 away from the first compression chamber 110, so that the first section 431 and the second section 434 can transition smoothly to a large extent, ensuring that the refrigerant can flow smoothly from the first section 431 to the second section 434, and reducing the flow resistance of the refrigerant.

[0095] In some embodiments, such as Figure 10As shown, the wall surface of the first groove segment includes a first arcuate surface 432 and two planar side surfaces 433 connected to the first arcuate surface 432, each planar side surface 433 being tangent to the first arcuate surface 432. The axis of the first groove segment is the axis of the first arcuate surface 432. That is, the outline of the inlet of the first segment 431 includes a semi-elliptical arc and two first straight lines connecting the two ends of the semi-elliptical arc, the first straight lines being tangent to the semi-elliptical arc. This greatly increases the inlet area of ​​the first segment 431, thereby further improving the intake volume of the second compression chamber 310.

[0096] The wall surface of the second groove segment is the second arc-shaped surface 435, and the axis of the second groove segment is the axis of the second arc-shaped surface 435. The diameters of the first arc-shaped surface 432, the second arc-shaped surface 435, and the second hole 412 are equal. The axis of the first groove segment and the axis of the second channel segment 420 are on the same plane, and the axis of the first groove segment and the axis of the second channel segment 420 intersect at the end face of the second cylinder body 300 facing the first compression chamber 110. When machining the third channel segment 430, the cutting tools (e.g., drill bits) used to machine the first segment 431 and the second segment 434 are of the same size. Therefore, the same cutting tool can be used to machine the first segment 431 and the second segment 434, eliminating the need to change cutting tools and thus further improving machining efficiency.

[0097] In addition, since the wall of the second section 434 is a second arc-shaped surface 435, the flow resistance when the refrigerant comes into contact with the second section 434 is reduced.

[0099] like Figure 11 As shown, the air conditioner 20 of this utility model embodiment includes the compressor 10 of any of the above embodiments.

[0100] The air conditioner 20 of this embodiment includes a compressor 10 comprising a first compression chamber 110 and a second compression chamber 310. The first compression chamber 110 is directly or indirectly connected to the intake passage 200, and the second compression chamber 310 is connected to the intake passage 200 via a diversion passage 400. The flow area of ​​the first intake section 210 of the intake passage 200 is the minimum flow area of ​​the intake passage 200. One end of the diversion passage 400 is disposed on the peripheral wall of the first intake section 210 of the intake passage 200, and the flow area of ​​the first intake section 210 is larger than the minimum flow area of ​​the diversion passage 400. This improves the structure of the intake passage 200 and the diversion passage 400, making the air intake of the intake passage 200 and the diversion passage 400 more uniform, thereby improving the output stability of the compressor 10 of this embodiment.
