Description
Technical Field
The utility model belongs to the technical field of compressors, and particularly relates to a compressor and an air conditioning system with the same.
Background
Along with the development of frequency conversion technology, the operating frequency of the scroll compressor is continuously increased, the pump body of the scroll compressor needs more oil to ensure lubrication and sealing effects under high-frequency operation, the oil supply quantity of the conventional scroll compressor is positively related to the rotating speed through an oil pump at the bottom of a crankshaft, along with the increase of the operating frequency, the oil quantity entering the pump body is rapidly increased, but the oil content of refrigerant gas discharged out of the pump body is also rapidly increased, and if the oil discharge rate of the compressor is increased without control, the integral performance of a refrigerating system is influenced. And if oil in the cavity of the compressor does not timely flow back to the oil pool at the bottom of the compressor, the oil shortage of the compressor can be caused, and the reliability of the scroll compressor is affected. There is a need to enhance the ability of the scroll compressor to separate oil droplets from the refrigerant gas and return the oil to the sump.
The traditional vertical scroll compressor does not relate to an independent oil-gas separation structure, and refrigerant flows along the inner wall of a compressor shell after leaving a compression cavity, so that oil drops contained in the refrigerant are adsorbed on the wall surface to realize oil-gas separation, and separated refrigerant gas is discharged along an exhaust pipe of the compressor. And the separated oil flows downwards in the form of an oil film under the action of gravity, and the flow speed is low. However, the oil adsorption and separation capacity of the wall surface is limited, and the oil film thickness of the wall surface can reach a maximum value due to the limitation of the oil return capacity, so that oil drops cannot be further adsorbed at the moment, and the oil content of the refrigerant gas cannot be reduced continuously.
Referring to fig. 1, the existing oil-gas separation mode is to adjust the opening position of the exhaust channel or add a guide plate structure, avoid the oily refrigerant gas from directly discharging from the exhaust pipe after leaving the compression cavity, and enhance the oil separation effect of the wall surface adsorption by increasing the movement distance of the refrigerant gas in the compressor shell. The refrigerant gas enters the upper cavity and the lower cavity of the motor from different channels, then moves to the exhaust pipe to be discharged, and the movement track is longer. However, the oil separation effect of the scheme is limited, and the oil separation effect is poor under the high-frequency operation of the compressor.

In the process of rotating the crankshaft 5, the guide piece 1 is driven to synchronously rotate, the guide piece 1 guides the refrigerant to the stator coil 6, the stator coil 6 is formed by repeatedly winding thin copper wires on the stator core 13, a porous structure with large surface area is formed, and when the refrigerant containing oil passes through the stator coil 6, a great amount of oil drop particles in the refrigerant can be adsorbed by the great surface area and gathered into large oil drops which fall along with gravity. According to the utility model, the flow guide piece 1 is arranged to enable the refrigerant to flow onto the stator coil 6 in a concentrated manner, so that the refrigerant is fully contacted with the porous stator coil 6, oil is adsorbed and separated on the surface of the stator coil 6, the oil content of the refrigerant is reduced, the effects of enhancing the oil-gas separation capability and accelerating the oil backflow to the oil tank 16 are realized, the oil discharge rate of the compressor is reduced, and the energy efficiency of an air conditioning system is improved.
Referring to fig. 4 and 5 in combination, the inner side of the guide member 1 has inner blades 101, and the inner blades 101 are used for pushing the refrigerant to flow toward the stator coil 6.

In this embodiment, during the rotation of the guide member 1, the inner layer blades 101 rotate synchronously, so as to generate thrust for the refrigerant flowing into the inner layer blades 101, and push the refrigerant to continue flowing in the air inlet direction; simultaneously, the outer layer blades 102 also synchronously rotate, and because the arrangement positions of the outer layer blades 102 and the inner layer blades 101 are different, the outer layer blades 102 can generate thrust to the refrigerant flowing into the outer layer blades 102, and the refrigerant is pushed to flow in the direction opposite to the air inlet direction. According to the utility model, by arranging two layers of blades, the blades generate driving force, so that the inner layer of blades 101 and the outer layer of blades 102 generate refrigerants with opposite flow directions, the structure is simple, the application range is wider, and different gas flow requirements are met.
The inner layer blades 101 and the outer layer blades 102 are inclined and have opposite inclination angles.
Referring to fig. 6 and 7 in combination, as a specific embodiment, the inclination angle between the outer side of the inner layer vane 101 and the horizontal direction is smaller than 0 °, and the inclination angle between the outer side of the outer layer vane 102 and the horizontal direction is larger than 0 °, and due to the existence of the inclination angle, the refrigerant flows in two directions when flowing to the guide member 1, so that different refrigerant flow direction requirements can be satisfied.
The guide piece 1 comprises a connecting ring 103 and a separating ring 104, wherein the connecting ring 103 is arranged on the inner side of the separating ring 104, and the connecting ring 103 is connected with the rotating shaft; a plurality of inner-layer blades 101 are arranged at intervals in the circumferential direction of the connecting ring 103, one ends of the inner-layer blades 101 are connected with the inner wall of the connecting ring 103, and the other ends of the inner-layer blades 101 are connected with a separation ring 104; the spacer ring 104 is provided with a plurality of outer layer blades 102 at intervals in the circumferential direction, and the plurality of outer layer blades 102 are connected to the outer wall of the connection ring 103.
In the present embodiment, the connection ring 103 serves to mount the inner-layer blades 101 and to be connected to the rotation shaft, and the partition plate can partition the refrigerant flowing into the inner-layer blades 101 and the outer-layer blades 102. When the air inlet direction is downward, the refrigerant flows into the inner layer blade 101 in the rotating process, and after the refrigerant flows onto the inner layer blade 101 due to the existence of the inclination angle, the inner layer blade 101 pushes the refrigerant to continuously flow downward under the action of centrifugal force, and the refrigerant on the outer layer blade 102 flows, and the outer layer blade 102 pushes the refrigerant to move upward. According to the utility model, the inner layer blades 101 and the outer layer blades 102 are obliquely arranged, and two refrigerants with opposite flow directions are generated by combining the centrifugal force generated in the rotation process of the guide piece 1, so that the flow path of the refrigerants is prolonged.
Referring to fig. 8 and 12, the outer layer blade 102 forms the first refrigerant flow path 21 during rotation, the inner layer blade 101 forms the second refrigerant flow path 22 during rotation, and the refrigerant in the second refrigerant flow path 22 flows into the stator coil 6 before flowing into the first refrigerant flow path 21.
In this embodiment, taking the case of the vertical arrangement of the compressor as an example, during the rotation of the guide member 1, the refrigerant flows downward, the inner layer blade 101 pushes the refrigerant to move downward to form the second refrigerant flow path 22, the refrigerant in the second refrigerant flow path 22 continues to flow downward, and the refrigerant flows through the stator coil 6 and then continues to flow downward into the gap between the stator core 13 and the rotor 15. The outer layer blades 102 drive the refrigerant to move upward, thereby sucking the refrigerant entering the motor into the first refrigerant flow path 21.
According to the utility model, under the pushing of the inner layer blades 101, the refrigerant in the second refrigerant flow path 22 passes through the stator coil 6, the stator coil 6 is formed by repeatedly winding thin copper wires on the stator core 13, a porous structure with a large surface is formed, and when the refrigerant containing oil passes through the stator coil 6, the oil drop particles in the refrigerant can be adsorbed by the extremely large surface area and gathered into large oil drops which fall along with gravity. The utility model changes the flow path of the refrigerant through the guide piece 1 to realize the effects of enhancing the oil-gas separation capability and accelerating the return of oil to the oil pool 16, thereby reducing the oil discharge rate of the scroll compressor and improving the energy efficiency of an air conditioning system. In addition, since the direction of movement of the refrigerant in the second refrigerant flow path 22 is vertically downward, the flow path of the refrigerant is extended, and the discharge of the oil droplets is promoted even when the refrigerant flows in the same direction as the falling direction of the large oil droplets.
The air conditioner further comprises a shell 3, the shell 3 is provided with a first chamber 301 and a second chamber 302, the air guide piece 1 is positioned in the first chamber 301, the refrigerant in the first refrigerant flow path 21 flows into the first chamber 301 to be discharged, and the refrigerant in the second refrigerant flow path 22 sequentially flows through the stator coil 6 and the second chamber 302 and then flows into the first refrigerant flow path 21 to be discharged from the first chamber 301.
As a specific embodiment, the compressor of the present utility model is a scroll compressor, the crank shaft 5 cooperating with the rotor 15 of the motor rotates to drive the movable scroll 12 to perform circular motion, the movable scroll 12 meshes with the fixed scroll 11 to compress the refrigerant, the first chamber 301 is located above the second chamber 302, the first chamber 301 is communicated with the exhaust chamber 9, the compressed refrigerant flows into the first chamber 301 from the exhaust chamber 9 along the passage on the side of the fixed scroll 11 and the upper bracket 10, and is discharged after oil-gas separation from the first chamber 301.
In the present embodiment, a stator circulation groove 14 is formed between the inner wall of the casing 3 and the outer wall of the stator core 13, the refrigerant in the second refrigerant flow path 22 flows through the gaps of the stator coil 6, the stator core 13 and the rotor 15 into the second chamber 302, in the second chamber 302, the oil drops continue to drop into the oil pool 16 below by inertia, and the refrigerant deflects toward the stator circulation groove 14, and the rising air flow generated by the outer layer blades 102 flows into the first refrigerant flow path 21, thereby being brought back into the first chamber 301. In the process that the refrigerant enters the second chamber 302 from the first chamber 301 and returns to the first chamber 301, the oil content of the refrigerant is greatly reduced. In addition, the refrigerant can also take away the heat generated by the stator in the process of passing through the stator coil 6, so that the temperature of the motor can be effectively reduced. And when the refrigerant passes through the porous stator coil 6 and enters the second chamber 302, the speed distribution is more uniform, the impact on the liquid level of the bottom oil pool 16 is small, and the splashing of oil to the second chamber 302 is avoided.
