[0040] The present application relates to the field of refrigeration, in particular to a compressor and air conditioner, the high-pressure gas of the existing scroll compressor is discharged by the static disc assembly, the high-pressure gas carries lubricating oil to form a gas-liquid mixture, when the gas-liquid mixture enters the upper cavity of the motor of the scroll compressor, part of the liquid droplets in the gas-liquid mixture is discharged by the exhaust pipe along with the gas, resulting in high oil discharge rate, and further resulting in low cooling capacity of the air conditioning system, heat exchange efficiency of the two devices is reduced, and the compressor is lubricated and lacks oil, etc. Hazards; part of the liquid droplets in the gas-liquid mixture entering the upper cavity of the motor adhere to the outer surface of the motor, resulting in low heat dissipation efficiency of the motor, affecting the working performance of the motor.

[0041] In view of the above technical problems, the present application provides a compressor and air conditioner.

[0042] As shown in Figures 1-3 The compressor comprises: a shell 1, a rotating shaft 2 and a gas flow channel are arranged in the shell 1, and a rotating block 3 is arranged on the rotating shaft 2; an oil separation cover 4 is fixed in the shell 1 and covers the outside of the rotating block 3, the oil separation cover 4 comprises a peripheral wall 401 and a bottom wall 402; a plurality of flow baffles 5 are arranged on the peripheral wall 401 around the rotating block 3, and a fluid passage 6 is formed between adjacent two flow baffles 5; the outlet of the gas flow channel leads to the rotating area of the rotating block 3; when the rotating shaft 2 rotates, the rotating block 3 can be driven to rotate to make the gas-liquid mixture flowing out of the fluid passage 6 outlet enter the fluid passage 6 and collide with the flow baffles 5.

[0043] The rotating shaft 2 rotates to drive the rotating block 3 to rotate, and the rotating block 3 drives the gas-liquid mixture entering the oil separation cover 4 to rotate, under the action of centrifugal force, the liquid drops with large particle size in the gas-liquid mixture move to the periphery and enter the fluid channel 6, and the liquid drops enter the fluid channel 6 and collide with the baffle 5 and adhere to the baffle 5 and flow downward to the bottom wall 402 under the action of gravity; the gas-liquid mixture containing liquid drops with small particle size directly collides with the baffle 5 and generates a baffle and vortex flow, and the liquid drops in the gas-liquid mixture are adsorbed to each other to form liquid drops with large particle size in the process of baffle and vortex flow, part of the liquid drops with large particle size move downward to the bottom wall 402 under the action of gravity, and part of the liquid drops collide with the baffle 5 under the action of gas flow and adhere to the baffle 5; since the liquid drops collide with the baffle 5 in the fluid channel 6, when the liquid drops collide with the baffle 5 and splash, the splashed liquid drops adhere to the baffle 5 again and flow downward to the bottom wall 402 under the action of gravity; if the liquid drop particle size is large, the liquid drop can finally adhere to the baffle 5 and flow downward to the bottom wall 402 under the action of gravity after multiple collisions with the baffle 5 in the fluid channel 6.

[0044] Preferably, as shown in the figure, one surface of the baffle 5 is protruded to form a protrusion 503; the protrusion 503 is located in the fluid channel 6 and forms a first interval 504 between the adjacent baffles 5. Figure 3

[0045] The fluid channel 6 includes the first interval 504, the gas-liquid mixture enters the fluid channel 6, and since the protrusion 503 is protruded in the fluid channel 6, the gas-liquid mixture flowing in the fluid channel 6 is more likely to collide with the protrusion 503 and generate a baffle and vortex flow, and the liquid drops in the gas-liquid mixture are separated in the process of baffle and vortex flow, part of the larger liquid drops flow downward to the bottom wall 402 under the action of gravity, part of the liquid drops directly adhere to the baffle 5 and flow downward, part of the liquid drops are adsorbed to each other to form larger liquid drops or move downward to the bottom wall 402, or adhere to the baffle 5 and move downward, or collide with the baffle 5 and splash, since the splashing process occurs in the fluid channel 6, the liquid drops after splashing are adsorbed, collide and splash for multiple times, and finally move downward to the bottom wall 402; the gas-liquid mixture continues to move to the outer edge after passing through the first interval 504.

[0046] The gas-liquid mixture can be further separated after passing through the first interval 504, preferably, as shown in the figure, the baffle 5 is provided with a second interval 505. Figure 3 ​As shown, the two plate surfaces of the baffle 5 are front surface and back surface respectively, the back surface of the baffle 5 is recessed so that the front surface of the baffle 5 is protruded; the recessed part of the back surface of the baffle 5 forms a groove 505, and the protruded part of the front surface of the baffle 5 forms a protrusion 503; the two adjacent baffles 5 are a first baffle 501 and a second baffle 502 respectively, the front surface of the first baffle 501 is opposite to the back surface of the second baffle 502, and the fluid channel 6 is located between the front surface of the first baffle 501 and the back surface of the second baffle 502.

[0047] After the part of the gas-liquid mixture collides with the protrusion 503 on the first baffle 501, it continues to flow to the peripheral wall 401 of the oil separation cover 4 and enters the groove 505 of the second baffle 502, and the gas-liquid mixture collides again in the groove 505 to generate a baffle and vortex, and the liquid droplets in the gas-liquid mixture are separated and move downward to the bottom wall 402; because the back surface of the baffle 5 is recessed to form the groove 505 at the same time, the front surface of the baffle 5 is protruded to form the protrusion 503, the groove 505 and the protrusion 503 increase the number of collisions of the gas-liquid mixture in the fluid channel 6, improve the gas-liquid separation effect, at the same time, the groove 505 and the protrusion 503 prolong the flow path of the gas-liquid mixture in the fluid channel 6, increase the area of interaction between the gas-liquid mixture and the baffle 5, and improve the separation effect of the liquid; because the groove 505 can form a more closed space than the protrusion 503, the collision, baffle and vortex of the gas-liquid mixture with the groove 505 are more violent than the collision, baffle and vortex of the gas-liquid mixture at the protrusion 503, which can separate out liquid droplets with smaller particle size.

[0048] To further improve the separation of liquid droplets in the gas-liquid mixture, after the gas-liquid mixture passes through the groove 505, preferably, as shown in Figures 1-3 As shown, the inner circumferential surface of the peripheral wall 401 is a cylindrical surface, and the opening direction of the fluid channel 6 in the radial direction of the peripheral wall 401 is opposite to the rotation direction of the rotating block 3; in this way, the gas-liquid mixture can more easily enter the fluid channel under the action of centrifugal force.

[0049] Further, the recess 505 of the baffle plate 5 can extend upward to the upper end surface of the baffle plate 5 and downward to the lower end surface of the baffle plate 5, so that the gas-liquid mixture can fully contact and collide with the protrusion 503 and the recess 505 in the up-down direction, thereby improving the droplet separation effect. The reverse surface of the baffle plate 5 includes a concave surface 506 of the recess 505 and a first plane 507 and a second plane 508 located on both sides of the concave surface 506, and the first plane 507 is connected with the cylindrical surface. The reverse surface of the baffle plate 5 is parallel to the axis of the rotating block 3, the first plane 507 and the cylindrical surface form an intersection straight line L, the plane P tangent to the cylindrical surface passes through the intersection straight line L, the included angle between the first plane 507 and the plane P is an acute angle, and the first plane 507 and the cylindrical surface form an oscillation space 7, and the fluid channel 6 includes the oscillation space 7.

[0050] By forming an acute angle between the first plane 507 and the plane P and rotating the rotating block 3 from the first baffle plate 501 to the second baffle plate 502, on the one hand, the rotating block 3 can make the centrifugal motion direction of the gas-liquid mixture consistent with the extension direction of the fluid channel 6 in the radial direction when rotating, so that the gas-liquid mixture can more easily enter the fluid channel 6. On the other hand, the acute angle between the first plane 507 and the plane P can form an oscillation space 7 between the first plane 507 and the cylindrical surface. The oscillation space 7 is more closed than the space in the recess 505. The collision, deflection and vortex of the gas-liquid mixture in the oscillation space 7 are more violent than those of the gas-liquid mixture with the recess 505. The droplet particle size separated in the oscillation space 7 is smaller than that separated in the recess 505.

[0051] In this way, the gas-liquid mixture sequentially passes through the protrusion 503, the recess 505 and the oscillation space 7 when entering the fluid channel 6. The protrusion 503, the recess 505 and the oscillation space 7 sequentially separate the droplets in the gas-liquid mixture in stages. The smaller the droplet particle size separated, the more downstream the gas-liquid mixture flows in the fluid channel 6, thereby effectively improving the efficiency of the droplet separation of the oil separation cover 4.

[0052] Further, the included angle between the first plane 507 and the second plane 508 can be β, and β is an obtuse angle. Further, the inlet diameter of the fluid channel 6 is small, the fluid channel 6 forms a relatively closed space, and the gas-liquid mixture can flow and collide more fully in the fluid channel 6.

[0053] Further, as shown in Figure 1 The circumferential wall 401 between the two adjacent baffle plates 5 forms a through hole 8 penetrating the circumferential wall 401, the part of the cylindrical surface between the through hole 8 and the straight line L forms a reflecting surface 403, and the reflecting surface 403 and the first plane 507 constitute the oscillation space 7. The gas-liquid mixture flowing through the fluid channel 6 is at least partially discharged from the oil separation cover 4 through the through hole 8.

[0054] After the gas-liquid mixture is separated in the fluid passage 6, the gas-liquid mixture containing less liquid droplets can be discharged from the through hole 8 of the oil separation cover 4, and of course can be discharged from the upper part of the oil separation cover 4; further, the plurality of baffles 5 are uniformly distributed along the circumference of the cylindrical surface; the filter screen is arranged at the through hole 8, and the filter screen is used to filter the liquid droplets and impurities in the gas-liquid mixture flowing through the through hole 8; the filter screen arranged at the through hole 8 can further separate the gas-liquid mixture after the gas-liquid mixture passes through the protrusions 503, the grooves 505 and the oscillation space 7, and can filter the solid impurities in the gas-liquid mixture, thereby improving the purity of the gas-liquid mixture and reducing the friction between the dynamic disc and the static disc.

[0055] Preferably, as shown in Figure 4 The connection between the bottom wall 402 and the peripheral wall 401 is concave downward to form an annular groove 404, and the bottom of the annular groove 404 forms an oil outlet 405; the second space 9 is formed between the baffles 5 and the surface of the bottom wall 402, and the liquid flowing downward from the baffles 5 to the bottom wall 402 can flow into the annular groove 404 through the second space 9, and the liquid in the annular groove 404 can flow out through the oil outlet 405; after the bottom wall 402 collects the liquid droplets separated by the oil separation cover 4, the liquid flows to the periphery through the second space 9 and enters the annular groove 404, so that the inner surface of the bottom wall 402 is high in the middle and low on the periphery, the oil outlet 405 is located at the lowest part of the groove, and the flow of the liquid on the bottom wall 402 and in the groove is accelerated, thereby avoiding the accumulation of the liquid on the bottom wall 402.

[0056] When the compressor is a scroll compressor, as shown in Figure 4 The scroll compressor comprises a support, the support is provided with a support fluid passage 12, the outlet of the support fluid passage 12 is connected to the rotating area of the rotating block, and the gas flow channel comprises the support fluid passage; the bottom wall 402 of the oil separation cover 4 is provided with a shaft hole 406, the oil separation cover 4 is sleeved on the rotating shaft 2 through the shaft hole 406 and is fixed on the support through the upper end of the peripheral wall 401; the outer wall surface of the peripheral wall 401 of the oil separation cover 4 and the inner wall surface of the oil separation cavity 11 form an annular cavity, the through hole 8 connects the inside of the oil separation cover 4 and the annular cavity; the oil outlet 405 of the annular groove 404 is connected to the oil pool through the oil discharge pipe 10; and the rotating shaft 2 is used to drive the dynamic disc assembly of the scroll compressor to move.

[0057] The scroll compressor is further provided with a static disc assembly fixed on the support, and the static disc assembly and the top wall of the shell 1 form an upper cavity of the pump body. The static disc assembly comprises a gas outlet at the upper end of the static disc assembly and a static disc flow-through groove at the edge of the static disc assembly. The gas outlet of the static disc assembly is communicated with the upper cavity of the pump body, the upper cavity of the pump body is communicated with the static disc flow-through groove, and the static disc flow-through groove is communicated with the support flow-through groove 12. The motor is provided with an output shaft, and the shaft 2 is connected with the dynamic disc assembly. When the motor works, the dynamic disc assembly rotates in a plane, and the rotating block 3 rotates. The rotating block 3 is a balance block of the dynamic disc assembly. The oil distribution cover 4 is fixed on the support through the upper end of the peripheral wall 401 of the oil distribution cover 4. The oil distribution cover 4 and the inner wall of the oil distribution cavity 11 form an annular cavity. The through hole 8 is communicated with the inner cavity of the oil distribution cover 4 and the annular cavity. The gas-liquid mixture flowing out of the through hole 8 enters the annular cavity and collides with the inner wall of the oil distribution cavity 11 under the action of centrifugal force, so that the liquid drops in the gas-liquid mixture adhere to the inner wall of the oil distribution cavity 11. The support communication groove is communicated with the inner cavity of the oil distribution cover 4, and the oil discharge port 405 is communicated with the oil pool through the oil discharge pipe 10. The liquid drops separated in the oil distribution cover 4 are collected on the bottom wall 402 and flow to the oil pool through the oil discharge pipe 10. The separated liquid drops directly flow downward to the surface of the motor, thereby improving the heat dissipation efficiency of the motor and ensuring the operation stability of the motor. In order to facilitate the fixing of the oil distribution cover 4 and the support, the support can form an outer circular surface, the diameter of the outer circular surface is slightly smaller than the diameter of the inner cylindrical surface of the oil distribution cover 4, the oil distribution cover 4 is sleeved on the outer circular surface of the support through the cylindrical surface of the oil distribution cover 4, and the oil distribution cover 4 can be fixed by welding or screws.

[0058] The gas-liquid mixture discharged from the outlet of the static disc assembly enters the oil distribution cover 4 in sequence through the upper cavity of the pump body, the static disc flow-through groove and the support flow-through groove 12. The balance block of the compressor is arranged in the oil distribution cover 4 as the rotating block 3. When the compressor works, the motor drives the dynamic disc assembly to move, and the balance block rotates to stir the gas-liquid mixture entering the oil distribution cover 4 and make the gas-liquid mixture do centrifugal motion and enter the fluid passage 6. The liquid drops separated in the separation cover are discharged through the oil discharge port 405 of the annular groove 404 and discharged to the oil pool through the oil discharge pipe 10, effectively avoiding the problem of insufficient lubricating oil caused by low oil level in the oil pool. The gas-liquid mixture discharged from the through hole 8 enters the annular cavity, the gas-liquid mixture in the annular cavity rotates under the driving of the motor rotor and collides with the inner wall of the annular cavity, and the gas-liquid mixture is separated again. The separated liquid drops adhere to the inner wall of the annular cavity and flow downward to the oil pool under the action of gravity. The distance between the balance block and the bottom wall 402 of the separation cover is controlled to be between 5-10 mm, so as to facilitate the flow of the liquid drops on the bottom wall 402.

[0059] The working process of the scroll compressor driven by the motor will be described below.

[0060] When the scroll compressor starts to work, the motor is energized to rotate, the output shaft of the motor, i.e. the rotating shaft 2 rotates, the rotating shaft 2 drives the moving disc assembly to move to compress the gas entering between the stationary disc assembly and the moving disc assembly, the compressed high-pressure gas contains lubricating oil, at this time the gas-liquid mixture is discharged from the gas outlet of the stationary disc assembly into the upper cavity of the pump body, and then passes through the stationary disc flow-through groove, the support flow-through groove 12, and enters the oil separation cavity 11, since the outlet of the support flow-through groove 12 is opposite to the upper end of the oil separation cover 4, the gas-liquid mixture flowing out of the support flow-through groove 12 flows downward into the oil separation cover 4 after entering the oil separation cavity 11;

[0061] When the rotating shaft 2 rotates, the balance block also rotates, that is, the rotating block 3 rotates, and the rotating block 3 drives the gas-liquid mixture in the oil distribution cover 4 of the oil distribution cover 4 to do centrifugal motion, and the movement direction of the centrifugal motion of the gas-liquid mixture is consistent with the extending direction of the fluid channel 6 in the radial direction; the gas-liquid mixture does centrifugal motion and enters the fluid channel 6, the liquid drops with large particle size in the gas-liquid mixture have large movement speed, the liquid drops with large particle size do centrifugal motion and collide with the flow baffles 5 on both sides of the fluid channel 6, when the liquid drops collide with the flow baffles 5, two results are caused, one is that the liquid drops adhere to the flow baffles 5 and flow downwards to the bottom wall 402, and the other is that the liquid drops splash into liquid drops with smaller particle size and move with the gas-liquid mixture in the fluid channel 6; the gas-liquid mixture continues to flow in the fluid channel 6 and collides with the protrusions 503 and generates a baffle and vortex flow, when the gas-liquid mixture collides with the protrusions 503, part of the liquid drops in the gas-liquid mixture adhere to the protrusions 503 and flow downwards to the bottom wall 402 under the action of gravity, in the process of the baffle and vortex flow, the liquid drops in the gas-liquid mixture collide with each other and absorb each other to form liquid drops with large particle size, part of the liquid drops formed by mutual absorption drop downwards to the bottom wall 402 under the action of gravity, since the gas-liquid mixture collides with the protrusions 503, the flow rate of the gas-liquid mixture is reduced, which is beneficial to the downward movement of the liquid drops under the action of gravity; part of the liquid drops continue to flow with the gas-liquid mixture and enter the recesses 505 and collide with the concave surfaces 506 of the recesses 505 and generate a baffle and vortex flow, when the gas-liquid mixture collides with the concave surfaces 506 of the recesses 505, part of the liquid drops in the gas-liquid mixture adhere to the concave surfaces 506 and flow downwards to the bottom wall 402 under the action of gravity, in the process of the baffle and vortex flow, the liquid drops in the gas-liquid mixture collide with each other and absorb each other to form liquid drops with large particle size, part of the liquid drops formed by mutual absorption drop downwards to the bottom wall 402 under the action of gravity; since the recesses 505 form a relatively closed space, the baffle and vortex flow of the gas-liquid mixture in the recesses 505 are more violent than the baffle and vortex flow formed by the protrusions, the liquid drops in the gas-liquid mixture collide with each other more violently and frequently in the baffle and vortex flow, so that the liquid drops with smaller particle size can absorb each other more fully, and the separation of the liquid drops in the gas-liquid mixture is further improved, since the gas-liquid mixture collides with the concave surfaces 506 of the recesses 505, the flow rate of the gas-liquid mixture is further reduced, which is beneficial to the downward movement of the liquid drops under the action of gravity;The gas-liquid mixture flows out of the groove 505 into the oscillation space 7 between the first plane 507 and the reflecting surface 403, collides with the first plane 507 and the reflecting surface 403, and generates a baffle and an eddy current in the oscillation space 7. When colliding with the first plane 507 and the reflecting surface 403, part of the liquid droplets in the gas-liquid mixture adhere to the first plane 507 and the reflecting surface 403 and flow downward to the bottom wall 402 under the action of gravity. In the process of the baffle and the eddy current, the liquid droplets in the gas-liquid mixture collide with each other and are adsorbed to form larger liquid droplets. The liquid droplets formed by mutual adsorption, part of which falls downward to the bottom wall 402 under the action of gravity, and part of which flows out into the annular cavity after being filtered by the filter screen through the through hole 8 on the peripheral wall 401; due to the acute angle between the first plane 507 and the plane P, the oscillation space 7 is more closed than the groove 505, the baffle and the eddy current of the gas-liquid mixture in the oscillation space 7 are more intense, and the mutual collision and adsorption between the liquid droplets in the gas-liquid mixture are also more intense and frequent, so as to further separate the liquid droplets in the gas-liquid mixture. Due to the collision of the gas-liquid mixture with the first plane 507 and the reflecting surface 403, the flow rate of the gas-liquid mixture is further reduced, which is beneficial to the downward movement of the liquid droplets under the action of gravity.

[0062] The gas-liquid mixture enters the fluid channel 6 in sequence through the protrusion 503, the groove 505 and the oscillation space 7, and the baffle and the eddy current generated by the gas-liquid mixture are intensified in sequence. The liquid droplets in the gas-liquid mixture are separated step by step, and the particle size of the separated liquid droplets also gradually decreases, improving the separation efficiency of the oil separation cover 4 on the liquid droplets in the gas-liquid mixture; when the gas-liquid mixture passes through the filter screen at the through hole 8, the liquid droplets in the gas-liquid mixture are again adsorbed by the filter screen and flow downward to the bottom wall 402 under the action of gravity; after the separated liquid droplets in the oil separation cover 4 flow onto the bottom wall 402, they flow along the bottom wall 402 under the action of gravity and enter the annular groove 404, and then flow along the groove under the action of gravity to the oil discharge port 405 of the annular groove 404. The oil discharge port 405 flows out and flows into the oil pool along the oil discharge pipe 10;

[0063] The gas-liquid mixture makes a circular motion in the annular cavity under the action of the rotor assembly of the motor, the liquid droplets in the gas-liquid mixture collide with the wall surface of the annular cavity and adhere to the wall surface of the annular cavity, and the liquid droplets adhered to the wall surface of the annular cavity flow downward to the oil pool under the action of gravity. After the gas-liquid mixture in the annular cavity separates the liquid droplets, it is discharged by the exhaust pipe on the casing 1 of the compressor; by separating the liquid droplets in the gas-liquid mixture, the oil discharge rate of the compressor is reduced, the oil amount of the lubricating oil in the oil pool of the compressor is stabilized, and the lubricating oil required for the parts in the compressor is ensured, thereby improving the working stability and reliability of the compressor.
