Description

Technical Field

[0001] This utility model relates to the technical field of compressors, and in particular to a compressor and its cylinder assembly. Background Technology

[0002] With the continuous improvement of people's living standards, air conditioners have become an indispensable household appliance. The compressor is a crucial component of an air conditioner. The compressor in this technology includes an upper cylinder, a lower cylinder, and a crankshaft. Upper and lower rollers are mounted on the crankshaft, located in the upper and lower cylinders respectively, ensuring that both cylinders receive 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 into the lower cylinder. However, during operation, only a small amount of refrigerant enters the distribution channel from the intake channel, resulting in uneven air intake between the upper and lower cylinders and consequently, poor compressor output stability.

[0004] One objective of this invention is to solve the problem of how to improve the output stability of compressors in related technologies.

[0005] Another objective of this invention is to address the problem of how to reduce the manufacturing difficulty of cylinder components.

[0006] Specifically, this utility model provides a cylinder assembly for a compressor.

[0007] This utility model also provides a compressor.

[0008] The cylinder assembly for a compressor of this utility model includes: a first compression chamber; an intake passage communicating with the first compression chamber to supply gas to the first compression chamber; a second compression chamber; and a diversion channel, one end of which is disposed on the peripheral wall of the intake passage, and the other end of which is communicating with the second compression chamber; and the diversion channel includes a first channel segment defined by a plurality of overlapping holes; the inlet of the first channel segment is larger than the outlet of the first channel segment.

[0009] In some embodiments, the axes of the plurality of holes intersect at the same point.

[0010] In some embodiments, the plurality of holes include: a first hole, the axis of the first hole and the axis of the air intake channel are on the same plane; the axis of the first hole is perpendicular to the axis of the air intake channel; a second hole, the axis of the second hole is intersecting the axis of the air intake channel and is on the same plane; the axis of the second hole is inclined toward the first compression chamber along the gas flow direction.

[0011] In some embodiments, the diameter of the first hole is equal to the diameter of the second hole; the angle between the axis of the second hole and the axis of the air intake passage is 50° to 70°.

[0012] In some embodiments, the cylinder assembly further includes: a first cylinder body, the first cylinder body defining the first compression chamber, the intake passage being disposed on the first cylinder body; a first passage segment being disposed on the first cylinder body and penetrating a corresponding end face of the first cylinder body; the axis of the intake passage being perpendicular to the axis of the first compression chamber and being on the same plane; the axis of the first hole being parallel to the axis of the first compression chamber; and the intersection of the axis of the first hole and the axis of the second hole being located on a corresponding end face of the first cylinder body.

[0013] In some embodiments, the cylinder assembly further includes: a partition plate disposed on one side of the first cylinder body; and the partition plate abutting against a corresponding end face of the first cylinder body; the portion of the corresponding end face of the first cylinder body that is in complete contact with the partition plate is a sealing area; the distance between the opening edge of the first channel segment on the corresponding end face of the first cylinder body and the inner edge of the sealing area is greater than or equal to 1 mm; the distance between the opening edge of the first channel segment on the corresponding end face of the first cylinder body and the outer edge of the sealing area is greater than or equal to 1 mm.

[0014] In some embodiments, the diversion channel further includes a second channel segment disposed on the partition, the axis of the second channel segment being parallel to or coincident with the axis of the second hole; the diameter of the second channel segment being greater than or equal to the diameter of the second hole.

[0015] In some embodiments, the difference between the diameter of the second channel segment and the diameter of the second hole is greater than or equal to 0.2 mm.

[0016] In some embodiments, the cylinder assembly further includes: a second cylinder body for defining the second compression chamber and disposed on the side of the partition away from the first cylinder body; the diversion channel further includes a third channel segment disposed on the second cylinder body, the third channel segment being a groove disposed on the peripheral wall of the second compression chamber and penetrating the end face of the second cylinder body facing the partition.

[0018] The cylinder assembly for a compressor according to this embodiment includes a first compression chamber and a second compression chamber.

This allows the intake channel to supply refrigerant to the first compression chamber, and a portion of the refrigerant in the intake channel to the second compression chamber via the diversion channel, thereby reducing the manufacturing cost of the cylinder assembly. Furthermore, because the inlet of the first channel section is larger than its outlet, the intake volume of the first channel section is increased, and the refrigerant flow in the intake channel can flow more smoothly into the first channel section. This reduces the resistance of the diversion channel to the refrigerant flow, thereby increasing the intake volume of the second compression chamber and reducing the performance difference between the first and second compression chambers, thus improving the output stability of the compressor.

[0043] The cylinder assembly 10 for a compressor 20 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0044] like Figures 1-8 As shown, the cylinder assembly 10 for the compressor 20 in this embodiment of the present invention includes a first compression chamber 110, an intake passage 200, a second compression chamber 310, and a flow divider passage 400.

[0045] The intake passage 200 communicates with the first compression chamber 110 to supply gas to the first compression chamber 110. One end of the diversion passage 400 is disposed on the peripheral wall of the intake passage 200, and the other end communicates with the second compression chamber 310. The diversion passage 400 includes a first channel section 410, which is defined by a plurality of overlapping holes. The inlet 401 of the first channel section 410 is larger than the outlet of the first channel section 410. That is, the inlet 401 of the first channel section 410 is formed at this end of the diversion passage 400, and the inlet 401 of the first channel section 410 is formed on the inner wall surface of the intake passage 200.

[0046] Refrigerant enters the compressor 20 through the inlet of the intake passage 200. 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 intake passage 200. Another portion of the refrigerant in the intake passage 200, when flowing through the inlet 401 of the first passage section 410, enters the diversion passage 400 through the inlet 401 of the first passage section 410, and flows into the second compression chamber 310 through the other end of the diversion passage 400.

[0047] Compared with related technologies, the cylinder assembly 10 for compressor 20 in this embodiment includes a first compression chamber 110 and a second compression chamber 310. The first compression chamber 110 is connected to the intake passage 200, and the second compression chamber 310 is connected to the intake passage 200 through a diversion passage 400. This allows refrigerant to be delivered to the first compression chamber 110 via the intake passage 200, and a portion of the refrigerant in the intake passage 200 to be delivered to the second compression chamber 310 via the diversion passage 400, thereby reducing the manufacturing cost of the cylinder assembly 10 in this embodiment. Furthermore, since the inlet 401 of the first channel section 410 is larger than the outlet of the first channel section 410, the intake volume of the inlet 401 of the first channel section 410 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. Consequently, the intake volume of the second compression chamber 310 is increased, reducing the performance difference between the first compression chamber 110 and the second compression chamber 310, thereby improving the output stability of the compressor 20.

[0048] Furthermore, since the structure of the inlet 401 of the first channel section 410 being larger than the outlet of the first channel section 410 is naturally formed by the overlapping of multiple holes, the processing difficulty of the first channel section 410 is greatly reduced.

[0049] In some embodiments, the axes of the multiple holes intersect at the same point. For example... Figure 5 As shown, the 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. Because the axes of the multiple holes intersect at the same point, the refrigerant airflow flowing from the intake channel 200 into the first channel section 410 is fully mixed at the intersection of the multiple holes. This avoids excessively high local flow velocities or eddies in the diversion channel 400, and facilitates smoother entry of the refrigerant into the second compression chamber 310.

[0050] In some embodiments, such as Figure 4 and Figure 5 As shown, 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.

[0051] It should be noted that the number of holes is not limited to two, but can also be three, four, five or other numbers. The axis of at least one of the holes is set at an angle so that the inlet 401 of the first channel segment 410 formed by the multiple holes is larger than the outlet.

[0052] Furthermore, such as Figure 5 As 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.

[0053] Further, 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.

[0054] 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°.

[0055] 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.

[0056] Specifically, such as Figure 1 The cylinder assembly 10 of this embodiment further includes a first cylinder body 100, which defines a first compression chamber 110. An intake passage 200 is disposed on the first cylinder body 100. A first channel segment 410 is disposed on the first cylinder body 100 and penetrates the corresponding end face of the first cylinder body 100. The axis of the intake passage 200 is perpendicular to the axis of the first compression chamber 110, and the axis of the intake passage 200 and the axis of the first compression chamber 110 are on the same plane. The axis of the first hole 411 is parallel to the axis of the first compression chamber 110, and the intersection of the axis of the first hole 411 and the axis of the second hole 412 is located on the corresponding end face of the first cylinder body 100. Thus, the intake passage 200 and the first channel segment 410 are directly machined on the first cylinder body 100, reducing structural redundancy and lowering manufacturing costs.

[0057] In some embodiments, the cylinder assembly 10 of this utility model further includes a partition 500, which is disposed on one side of the first cylinder body 100 and abuts against the corresponding end face of the first cylinder body 100. The portion of the corresponding end face of the first cylinder body 100 that is in complete contact with the partition 500 is a sealing area, thereby preventing air leakage between the first cylinder body 100 and the partition 500.

[0058] 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.

[0059] 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 5 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.

[0060] 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 5 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.

[0061] 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.

[0062] In some embodiments, such as Figure 6 and Figure 7 As shown, the diversion channel 400 also includes a second channel section 420, which is disposed on the partition 500. The axis of the second channel section 420 is parallel to or coincides with the axis 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.

[0063] Furthermore, the diameter of the second channel segment 420 is greater than or equal to the diameter of the second hole 412. This makes it easier for the inlet of the second channel segment 420 to fully connect with the outlet of the first channel segment 410, thus reducing the difficulty of assembling the inlet of the second channel segment 420 with the second hole 412 during installation.

[0064] Optionally, the difference between the diameter of the second channel segment 420 and the diameter of the second hole 412 is greater than or equal to 0.2 mm. That is, the difference between the diameter of the second channel segment 420 and the diameter of the second hole 412 includes, but is not limited to, 0.2 mm, 0.22 mm, 0.25 mm, 0.3 mm, 0.37 mm, or 0.4 mm.

[0065] Furthermore, the cylinder assembly 10 of this utility model embodiment also includes a second cylinder body 300, which is used to define a second compression chamber 310. The second cylinder body 300 is disposed on the side of the partition 500 opposite to the first cylinder body 100.

[0066] In some embodiments, such as Figure 8 and Figure 9 As shown, the diversion channel 400 includes a third channel section 430, which is disposed within the peripheral wall of the second compression chamber 310. The third channel section 430 includes a first section 431 and a second section 434 connected in sequence. The axes of the first section 431 and the second section 434 intersect and lie on the same plane. Along the gas flow direction, both the axes of the first section 431 and the second section 434 are inclined towards the second compression chamber 310. Because both axes of the first section 431 and the second section 434 are 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. The inclination angle of the axis of the second section 434 is greater than the inclination angle of the axis of the first section 431.

[0067] Specifically, the third channel section 430 is disposed on the second cylinder body 300. The third channel section 430 is a groove disposed on the peripheral wall of the second compression chamber 310 and penetrating the end face of the second cylinder body 300 facing the partition plate 500. That is to say, the second section 434 is inclined towards the second compression chamber 310 to a greater extent than the first section 431 is inclined towards the second compression chamber 310.

[0068] The third channel section 430 includes a first section 431 and a second section 434 connected in sequence. The axes of both the first section 431 and the second section 434 are inclined towards the second compression chamber 310. Since the inclination angle of the second section 434's axis is greater than that of the first section 431's axis, 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. This significantly reduces the flow resistance of the refrigerant within the third channel section 430, thereby minimizing 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 20 is improved.

[0069] 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 cylinder assembly 10 in this embodiment and lowering manufacturing costs.

[0070] 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.

[0071] In some embodiments, the third channel segment 430 is a groove disposed on the peripheral wall of the second compression chamber 310. That is, the wall surface of the groove directly forms the third channel segment 430, increasing the flow area of ​​the refrigerant, thereby facilitating an increase in the intake volume of the second compression chamber 310. Furthermore, directly slotting the peripheral wall of the second compression chamber 310 to form the third channel segment 430 reduces manufacturing difficulty.

[0072] Specifically, the wall surface of the first section 431 includes a first arcuate surface 432 and two planar side surfaces 433 connected to the first arcuate surface 432. Each planar side surface 433 is tangent to the first arcuate surface 432, and the axis of the first section 431 is the axis of the first arcuate surface 432. That is to say, the outline of the inlet of the first section 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 section 431, thereby further improving the intake volume of the second compression chamber 310.

[0073] Furthermore, the wall surface of the second segment 434 is a second arc-shaped surface 435, and the axis of the second segment 434 is the axis of the second arc-shaped surface 435. The diameter of the first arc-shaped surface 432 is equal to the diameter of the second arc-shaped surface 435. That is to say, 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 and specifications. 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.

[0074] 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.

[0075] Furthermore, for example Figure 8 As shown, the tilt angle of the axis of the first segment 431 is b, and the tilt angle of the axis of the second segment 434 is c. The tilt angle of the axis of the first segment 431 is between 100° and 120°. Specifically, the tilt angle of the axis of the first segment 431 includes, but is not limited to, 100°, 102°, 109°, 110°, 114°, 116°, 117°, 118°, or 120°. The tilt angle of the axis of the second segment 434 is between 120° and 140°. Specifically, the tilt angle of the axis of the second segment 434 includes, but is not limited to, 120°, 122°, 126°, 130°, 134°, 136°, 137°, 139°, or 140°. The tilt angle of the axis of the second channel segment 420 is between 100° and 120°. The tilt angle of the axis of the second channel section 420 includes, but is not limited to, 100°, 102°, 109°, 110°, 114°, 116°, 117°, 118°, or 120°. This allows the refrigerant airflow to smoothly enter the second compression chamber 310 by sequentially passing through the second channel section 420, the first section 431, and the second section 434. Furthermore, it avoids the angles between the second channel section 420, the first section 431, and the second section 434 and the vertical direction being too small, which would result in an excessively large overall size of the second channel section 420, the first section 431, and the second section 434 in the vertical direction, thereby reducing the overall size of the cylinder assembly 10 and lowering manufacturing costs.

[0076] The compressor 20 of this utility model is described below with reference to the accompanying drawings.

[0077] like Figure 10 As shown, the compressor 20 of this utility model embodiment includes the cylinder assembly 10 of any of the above embodiments.

[0078] The compressor 20 of this embodiment includes a cylinder assembly 10 comprising a first compression chamber 110 and a second compression chamber 310. The first compression chamber 110 is connected to the intake passage 200, and the second compression chamber 310 is connected to the intake passage 200 via a diversion passage 400. Since the inlet 401 of the first passage section 410 is larger than the outlet of the first passage section 410, the intake volume of the inlet 401 of the first passage section 410 is increased. Furthermore, the refrigerant flow in the intake passage 200 can flow more smoothly into the first passage section 410, reducing the resistance of the diversion passage 400 to the refrigerant flow. This, in turn, increases the intake volume 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 20 of this embodiment.
