Description

Technical Field

[0001] This invention relates to the technical field of energy-saving motors, and specifically to a flow structure for a scroll compressor housing. Background Technology

[0002] Currently, scroll compressors are widely used as core power components in air conditioning, refrigeration, and heat pump systems. Their working principle primarily relies on the meshing of a stationary scroll and a moving scroll, forming multiple pairs of crescent-shaped compression chambers that move from the outer periphery to the center with their revolution. Traditional scroll compressors typically employ a constant tooth height structure for the scroll teeth, with a flat base plate. The compression chambers only undergo volume changes from large to small within the radial plane, and gas compression is mainly achieved through radial volume contraction. However, in actual operation, the traditional constant tooth height planar scroll structure has certain limitations: firstly, the rate of volume change in the compression chamber is limited by the planar profile, making it difficult to further improve the single-stage compression ratio; secondly, repeated friction in the axial clearance can easily cause gas leakage, affecting the compressor's volumetric efficiency and energy efficiency level. Summary of the Invention

[0003] In order to solve the above-mentioned problems in the prior art, the present invention aims to provide a scroll compressor housing flow structure with simple structure, high single-stage compression ratio, and no further expansion of shaft clearance due to friction.

[0004] The technical solution adopted in this invention is as follows: A scroll compressor housing flow structure, including a housing placed inside an air conditioner, and a compression module for compressing gas is provided inside the housing for compressing gas; The gas compression module includes a partially abutting main vortex block and an auxiliary vortex block, both of which have a planar spiral structure. A sealing cavity plate and a bottom fastening plate are respectively provided on the open sides of the gas compression module. An exhaust pipe is provided on the sealing cavity plate. The main vortex block passes through and is slidably connected to the sealing cavity plate. The side of the gas compression module away from the sealing cavity plate has a uniform spherical concave opening. A spherical protrusion is provided in the middle of the bottom fastening plate. The middle of the bottom fastening plate abuts against the main vortex block and is fixedly connected to the auxiliary vortex block. A sealing ring plate surrounding the gas compression module is provided between the bottom fastening plate and the main vortex block. An air inlet pipe is provided on the sealing ring plate. A power module is also provided on the bottom fastening plate to drive the bottom fastening plate to rotate cyclically.

[0005] In one embodiment, the housing includes a compressor cylinder body, with the ends of the compressor cylinder body respectively disposed on a dome cover and a bottom cover, the intake pipe passing through the compressor cylinder body, the exhaust pipe exiting the dome cover, and the power module positioned above the bottom cover.

[0006] In one embodiment, the power module includes a drive motor, which is fixedly connected to the inner cavity. The drive motor is supported and connected to the bottom cover by a support bearing. The output shaft end of the drive motor is provided with an oblique bending rod, which has an oblique bending structure. One end of the connecting block is rotatably connected to the center of the bottom fastening plate.

[0007] In one embodiment, the compressor cylinder has an insulating plate inside, which is rotatably connected through the drive motor shaft and divides the housing into two cavities, with the compression module placed in one of the cavities.

[0008] In one embodiment, a swing block is provided on the periphery of the bottom fastening plate, and a swing groove is provided on the swing block. The swing groove passes through the swing block. A fixedly connected lever is provided on the inner cavity side of the compressor body. The lever passes through and is slidably connected to the swing groove. The lever and the swing groove cooperate to move the bottom fastening plate by bending the lever obliquely.

[0009] In one embodiment, a thrust plate is provided on the side of the main vortex block that extends out of the sealing cavity plate. The main vortex block abuts against the thrust plate. The thrust plate is penetrated by the exhaust pipe. A top pressing plate is provided at the end of the thrust plate away from the main vortex block. The top pressing plate is fixedly connected to the inner cavity of the compressor cylinder by a connecting block. Several thrust springs are evenly arranged between the top pressing plate and the thrust plate.

[0010] In one embodiment, the main vortex block and the auxiliary vortex block are made of nickel-titanium alloy.

[0011] In one embodiment, the main vortex block and the auxiliary vortex block include two sets of axially symmetrically arranged movable plates. Several interlocking plates are provided on opposite sides of the two sets of movable plates. The interlocking plates are provided with V-shaped interlocking notches. The interlocking notches between two adjacent sets of interlocking plates interlock with each other. Long connecting plates and short connecting plates are provided at both ends of the movable plates respectively. The long connecting plates abut against the opposite sides of the adjacent movable plates, and the short connecting plates fasten to the outer side of the long connecting plates.

[0012] In one embodiment, one end of each of the two sets of movable plates is provided with a sealing plate to cover the cavity of the two sets of movable plates.

[0013] In one embodiment, the bite plates are arranged in a horizontal and vertical array, with adjacent columns of bite plates staggered sequentially.

[0014] The beneficial effects of this invention are as follows: It features a simple structure, a high single-stage compression ratio, and a scroll compressor housing flow structure that prevents further expansion of the shaft clearance due to friction. Specific implementation effects are shown below: After gas is introduced through the intake pipe, it flows into the cavity formed by the sealing ring plate, sealing cavity plate, and bottom fastening plate. At this point, the drive motor is activated. During the rotation of the drive motor, the oblique bending rod deflects the bottom fastening plate. Simultaneously, due to the guiding effect of the swing block on the deflector column, the rotation of the bottom fastening plate is transformed into a swinging motion by the sequential fixation of certain areas. This, combined with the auxiliary and main vortex blocks, achieves the effect of vortex compression, similar to existing technologies. However, because the main vortex block can slide within the sealing cavity plate, a new effect is produced during vortex compression: a progressively smaller crescent-shaped cavity. Because the bottoms of the main and auxiliary vortex blocks are spherical concave, they abut against the spherical protrusions of the bottom fastening plate. The compression ratio in the middle of this cavity is significantly higher than that at the front end, further improving the single-stage compression ratio. The auxiliary scroll block has a spherical concave bottom, which creates a large air leakage gap during rotation, affecting compression efficiency. Both the auxiliary and main scroll blocks are made of high-toughness materials. When the bottom clamping plate drives the auxiliary scroll block to rotate, the main scroll block is subjected to the thrust force of the thrust spring on the top pressing plate. The main scroll block slides within the sealing cavity plate. Since the main scroll block is composed of two sets of movable plates, the two sets of movable plates abut against the spherical protrusions of the bottom clamping plate at different positions during spiral compression. This creates a double-spiral sealing structure with the central vortex of the main scroll block as support and the outer spiral gradually moving away, similar to a spring with a gradually expanding outer diameter. This reduces the air leakage gap without increasing the gap due to friction, and it is not necessary to completely eliminate the gap. Traditional scroll compressors also have gaps; otherwise, they would cause a series of problems such as the inability to rotate.

[0015] Specifically, the two sets of movable plates form a cavity of movable size under the abutting action of the long and short connecting plates. The cavity deforms when the main vortex block moves. However, since this type of material is very easy to deform under pressure, the abutting interlocking plates are designed. Due to the interlocking notches, the interlocking plates provide support at the deformation point and provide restoring elasticity when misaligned. Since the abutting relationship is maintained between the bottom fastening plate and the main vortex block, the problem of gap expansion after high-frequency friction is also solved.

[0016] This structure, by adjusting the structure and active area of ​​the main vortex block and the auxiliary vortex block, achieves a better compression ratio when the auxiliary vortex block rotates, while solving the problem of increased friction gap. It has good practicality and economy, and is beneficial to the promotion and use of equipment. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0022] The following is combined with Figure 1-7 This invention describes a specific embodiment of a scroll compressor housing flow structure, which includes a housing placed inside an air conditioner. The housing is adjusted according to the shape of the air conditioner to avoid being too large or too small. A compression module for compressing gas is provided inside the housing. The gas compression module includes a partially abutting main vortex block 34 and an auxiliary vortex block 35. The shape can adopt the compression area shape of a general scroll compressor. The specific vortex parameters are existing technology and will not be described in detail. The principle of the existing scroll compressor is that the stationary scroll disk and the moving scroll disk mesh with each other to form a compression chamber. The volume of the compression chamber gradually decreases from the outer periphery to the center through the revolution of the moving scroll disk, thereby realizing gas compression. In this patent, the main vortex block 34 and the auxiliary vortex block 35 have a planar spiral structure on one side. The open surfaces on both sides of the gas compression module are respectively provided with a sealing cavity plate 33 and a bottom fastening plate 36. The sealing cavity plate 33 is provided with an exhaust pipe 12 for discharging high-pressure gas from the center. Similar to the prior art, the main vortex block 34 passes through and is slidably connected to the sealing cavity plate 33. The other side of the gas compression module away from the sealing cavity plate 33 has a uniform spherical concave opening. Specifically, after the gas is input through the air inlet pipe 11, the gas flows into the cavity formed by the sealing ring plate 331, the sealing cavity plate 33, and the bottom fastening plate 36. At this time, the drive motor 21 is started. During the rotation of the drive motor 21, the oblique bending rod 211 oscillates the bottom fastening plate 36 to rotate. At the same time, due to the guiding effect of the swing block 361 on the lever column 363, when the bottom fastening plate 36 rotates, the fixation of the bottom fastening plate 36 in a certain area in sequence makes the rotation of the bottom fastening plate 36 become a swinging winding, which, together with the auxiliary vortex block 35 and the main vortex block 34, achieves the effect of vortex compression. Compared to existing scroll compressors, which employ a constant tooth height structure for their scroll teeth and a flat bottom plate for the scroll disk, the existing scroll compressors only achieve volume changes from large to small within the radial plane, with gas compression primarily achieved through radial volume contraction. In contrast, in this invention, the main scroll block 34 can slide within the sealed cavity plate, and both the main scroll block 34 and the auxiliary scroll block 35 have spherical concave bottoms that abut against the spherical protrusions of the bottom fastening plate 36. This results in a significantly higher compression ratio within the structural cavity in the middle compared to the front compression area, further enhancing the single-stage compression ratio.

[0023] Specifically, the spherical concave surfaces of the main vortex block 34 and the auxiliary vortex block 35 are the same spherical surface, using a screw-in recessed form. The bottom fastening plate 36 has a spherical protrusion in the middle, and the middle of the bottom fastening plate 36 abuts against the main vortex block 34 and is fixedly connected to the auxiliary vortex block 35. A sealing ring plate 331 surrounding the gas compression module is provided between the bottom fastening plate 36 and the main vortex block 34. An air inlet pipe 11 is provided on the sealing ring plate 331. The upper part is also equipped with a power module to drive the bottom fastening plate 36 to rotate in a circular motion. The rotation method is the same as the existing vortex rotation method and can be adjusted according to the actual situation. Specifically, the friction part can use soft materials or isolation gaps similar to existing technologies, and can be controlled according to the actual situation, such as noise and cost. The main vortex block 34 can slide in the sealing cavity plate 33, which can produce a new effect during vortex pressing. The crescent-shaped cavity shrinks step by step. Since the bottom of the main vortex block 34 and the auxiliary vortex block 35 is a spherical concave opening, it is connected to the bottom fastening plate 36. The spherical protrusion of the plywood 36 creates contact, and the compression ratio in the structural cavity in the middle of the two is significantly higher than that at the front end. The single-stage compression ratio is further improved. The lifting position of the main vortex block 34 will also deform with the spherical protrusion of the bottom fastener plywood 36. The elastic deformation of the main vortex block 34 can be preset, so that it has a structural tendency to spiral outward before it moves, in order to meet the actual pressure holding requirements. Furthermore, the above structure can adaptively adjust the strength of the spherical concave opening of the main vortex block 34. Beneficially, the housing includes a compressor cylinder 1, with the ends of the compressor cylinder respectively located at a dome cover 102 and a bottom cover 101. An intake pipe 11 passes through the compressor cylinder 1, and an exhaust pipe 12 exits from the dome cover 102. The power module is located above the bottom cover 101. This structure is a traditional support structure, mainly utilizing existing pre-reserved installation locations in air conditioners, etc., making it easy to promote and use. Specifically, the power module includes a drive motor 21. The attached diagram does not show the fixed structure, but it is actually adjusted according to the actual situation. The drive motor 21 can be a DC or AC motor, which is automatically switched according to the driving amount and equipment requirements. The drive motor 21 is fixedly connected to the inner cavity. The drive motor 21 is supported and connected to the bottom cover 101 by the support bearing 22 to prevent the drive motor 21 from loosening or falling off due to vibration after bearing the load. The output shaft end of the drive motor 21 is provided with a slanted bending rod 211. The slanted bending rod 211 has a slanted bending structure. One end of the connecting block 311 is rotatably connected to the center of the bottom fastening plate 36 for turning and rotating the bottom fastening plate 36.

[0024] Beneficially, the inner cavity of the compressor body 1 is provided with an isolation plate 13. The isolation plate 13 is rotatably connected by the rotating shaft of the drive motor 21 and divides the housing into two cavities. The compression module is placed in one of the cavities, which can prevent gas leakage and maintain pressure. In practice, the position of the dome cover 102 is more compact. At the same time, even if there is a leak, the gas can be protected between the dome covers 102.

[0025] Beneficially, the bottom fastening plate 36 is provided with a swing block 361 on its periphery, and a swing groove 362 is provided on the swing block 361. The swing groove 362 can be adjusted to a straight groove or a curved groove according to the vortex pitch and the rotation axis; the specific configuration can be determined according to the actual situation. The swing groove 362 passes through the swing block 361. The compressor cylinder body 1 is provided with a fixedly connected lever column 363, which can be connected by a bracket or connecting block, as long as it does not affect the movement stroke. The lever column 363 passes through and slides to the swing groove 362. The lever column 363 and the swing groove 362 cooperate with the inclined bending rod 211 to move the bottom fastening plate 36. Specifically, this avoids rotating the auxiliary vortex block 35 when deflecting, and only allows for swinging and winding rotation.

[0026] Beneficially, a thrust plate 32 is provided on the side of the main vortex block 34 that extends out of the sealing cavity plate 33. The main vortex block 34 abuts against the thrust plate 32. The thrust plate 32 is penetrated by the exhaust pipe 12. A top pressing plate 31 is provided at the end of the thrust plate 32 away from the main vortex block 34. The top pressing plate 31 is fixedly connected to the inner cavity of the compressor cylinder 1 by the connecting block 311. Several thrust springs 321 are evenly arranged between the top pressing plate 31 and the thrust plate 32. In implementation, it can assist the concave side of the main vortex block 34 to fit against the bottom fastening plate 36. However, during the movement, often only part of the main vortex block 34 at the center and part of the inner ring abut against each other, and they will not fit completely.

[0027] Beneficially, the main vortex block 34 and the auxiliary vortex block 35 are made of nickel-titanium alloy, which has high elasticity, high toughness and high recovery ability, making it more suitable for this scenario.

[0028] Beneficially, the main vortex block 34 and the auxiliary vortex block 35 include two sets of axially symmetrically arranged movable plates 341. Several interlocking plates 343 are provided on opposite sides of the two sets of movable plates 341. The interlocking plates 343 have V-shaped interlocking notches 3431. The interlocking notches 3431 of similar interlocking plates 343 interlock with each other, but in case of misalignment, the structure will not create a blocking effect; instead, elastic support will be provided by deformation, preventing damage to the movable plates 341. During operation, the sliding area is locked in place. Both ends of the movable plate 341 are respectively provided with a long connecting plate 3411 and a short connecting plate 342. The long connecting plate 3411 abuts against the opposite side of adjacent movable plates 341, and the short connecting plate 342 fastens to the outside of the long connecting plate 3411. Specifically, one end of each set of movable plates 341 is provided with a sealing plate to cover the cavity of the two sets of movable plates 341. The attached figure shows a cross-section of the middle section. Advantageously, several interlocking plates 343 are arranged in a horizontal and vertical array, with adjacent vertical interlocking plates 343 staggered sequentially. In practice, due to the special properties of the material, bending may occur under high pressure, and gaps may also occur during deformation. This is addressed by using the main vortex block 34... The auxiliary vortex block 35 is changed to a cavity-type abutment structure. With slight deformation, the movable plate 341 and the extended plate 3411 seal the cavity. The gap between the contact surfaces can be abutted by two sets of movable plates 341, reducing the risk of air leakage. The staggered interlocking plates 343 improve mutual support, preventing bending of the movable plate 341 due to pressure in the middle. This solves the aforementioned problems and, with these effects, allows the main vortex block 34 and auxiliary vortex block 35 to better adapt to the relative movement between the spherical concave and spherical convex surfaces during compression. The flexible adjustment of the movable plates and the elastic support of the interlocking plates further optimize the sealing performance and reduce the leakage rate. Simultaneously, the use of nickel-titanium alloy material ensures that the structure maintains stable performance under long-term, high-frequency deformation and friction, extending the equipment's service life. This design not only improves the single-stage compression ratio but also effectively balances the relationship between compression efficiency and structural stability through a dynamic adjustment mechanism.

[0029] Working principle of this invention: After gas is input through the intake pipe 11, it flows into the cavity formed by the sealing ring plate 331, the sealing cavity plate 33, and the bottom fastening plate 36. At this time, the drive motor 21 is started. During the rotation of the drive motor 21, the oblique bending rod 211 oscillates and rotates the bottom fastening plate 36. At the same time, due to the guiding effect of the swing block 361 on the lever column 363, the rotation of the bottom fastening plate 36 is changed to swinging and winding due to the partial fixation of the bottom fastening plate 36. This, together with the auxiliary vortex block 35 and the main vortex block 34, achieves the effect of vortex compression, which is the same as the prior art. However, since the main vortex block 34 can slide in the sealing cavity plate 33, a new effect can be produced during vortex compression. The crescent-shaped cavity shrinks step by step. Since the bottom of the main vortex block 34 and the auxiliary vortex block 35 is a spherical concave opening, it abuts against the spherical protrusion of the bottom fastening plate 36. The compression ratio in the middle of the cavity is significantly higher than that at the front end. The single-stage compression ratio is further improved. The bottom of the vortex block 34 and the auxiliary vortex block 35 is a spherical concave opening, which will generate a large air leakage gap during rotation, affecting the compression efficiency. The auxiliary vortex block 35 and the main vortex block 34 are made of high toughness material. When the bottom fastening plate 36 drives the auxiliary vortex block 35 to rotate, the main vortex block 34 will be pushed by the thrust spring 321 on the top pressing plate 31 against the thrust plate 32. The main vortex block 34 slides in the sealing cavity plate 33. Since the main vortex block 34 is spliced ​​by two sets of movable plates 341, the two sets of movable plates 341 abut against the spherical protrusions of the bottom fastening plate 36 at different positions during spiral compression, creating a double spiral sealing structure with the central vortex of the main vortex block 34 as support and the outer spiral gradually moving away, similar to a spring with a gradually expanding outer diameter. This can reduce the air leakage gap, and at the same time, it will not cause the gap to increase due to friction, nor is it necessary to completely eliminate the gap. Traditional scroll compressors also have gaps, otherwise, a series of problems such as the inability to rotate will occur.

[0030] Specifically, the two sets of movable plates 341 form a cavity of movable size under the abutting action of the long connecting plate 3411 and the short connecting plate 342. The cavity deforms when the main vortex block 34 moves. However, since this type of material is very easy to deform under pressure, the abutting biting plate 343 is designed. Due to the interlocking notches 3431, the interlocking plates provide support at the deformation point and provide restoring elasticity when misaligned. Since the abutting relationship is maintained between the bottom fastening plate 36 and the main vortex block 34, the problem of gap expansion after high-frequency friction is also solved.
