[0057] Under low-temperature heating conditions of the air conditioner, the energy efficiency attenuation is large, resulting in low APF energy efficiency of the air-conditioning system. The reason is that the compressor in the air conditioner discharges a large amount of oil under low-temperature heating conditions. The large amount of oil discharged by the compressor will cause the formation of oil film, which reduces the heat exchange efficiency of the air-conditioning system, thereby reducing the energy efficiency of the air-conditioning system.

[0058] Based on this, the following embodiments are proposed.

[0059] Embodiment 1:

[0060] This embodiment provides an oil discharge control assembly, which is arranged on a rotor, and the oil discharge control assembly includes:

[0061] A housing 1 is formed with a cavity 2, and the housing 1 has two relatively parallel first walls 101 and a second wall 102, the first wall 101 is provided with a plurality of first through holes 103 circumferentially spaced around the rotor axis, the second wall 102 is provided with a plurality of second through holes 104 circumferentially spaced around the rotor axis, and the plurality of first through holes 103 and the plurality of second through holes 104 are axially corresponding to each other in pairs to form a plurality of oil hole groups;

[0062] A control member 3, the control member 3 is disposed in the cavity 2 and has a first plate surface opposite to the first wall 101 and a second plate surface opposite to the second wall 102, the control member 3 is provided with a plurality of conducting holes penetrating the first plate surface and the second plate surface, the plurality of conducting holes are distributed at intervals along the circumference of the rotor, and can be connected to different oil hole groups as the rotation angle of the control member 3 is different;

[0063] The control member 3 is in driving connection with the rotor, and the control member 3 can rotate within a preset angle range relative to the housing 1;

[0064] A damping component 4 capable of deforming in the relative rotation direction between the control member 3 and the housing 1 is provided between the control member 3 and the housing 1;

[0065] The housing 1 and the control member 3 are configured such that, under different rotation speeds of the rotor and the action of the damping assembly 4 , the plurality of oil hole groups and the plurality of conducting holes form conductions with different oil flow rates.

[0066] In this embodiment, the oil discharge control component is used for a compressor. During operation of the compressor, its rotor drives the control component 3 to rotate. During this process, the housing 1 rotates along with the rotation of the control component 3, and the housing 1 does not interfere with the rotor. The compressor in the air conditioner discharges a large amount of oil under low-temperature heating conditions. A large amount of oil discharged by the compressor will cause the formation of an oil film, and the oil film generally covers the pipe wall in the air-conditioning system, resulting in a decrease in the heat exchange efficiency of the air-conditioning system. In addition, the oil discharged by the compressor is refrigeration oil, which takes away the heat of the air-conditioning system to a certain extent, further resulting in a decrease in the heating efficiency of the air-conditioning system.

[0067] Preferably, the housing 1 can be constructed as a rotor baffle in a compressor or the rotor baffle in the compressor can be directly set as a cavity structure as the housing 1 in the oil discharge control assembly. This structure is simple, low-cost, does not rely on an external control module, and enables the control component 3 to effectively control the oil discharge of the compressor.

[0068] The oil outlet control component in this embodiment is as follows: Figure 2As shown, the rotor drives the control member 3 in the second speed state, and the second speed state is the high-frequency operation of the compressor. At this time, the rotor rotates at a high speed, and it drives the control member 3 to rotate at a high speed. In this state, the control member 3 is limited in the second position by the damping component 4, that is, the control member 3 drives the shell 1 to rotate in the second position. In this state, there is an offset between the oil hole group and the conducting hole, that is, when the compressor is in the high-frequency operation state, some of the multiple oil hole groups are in an open state, and the other part is in a closed state, that is, the oil discharge amount of the compressor is reduced accordingly, and the oil discharge amount can maintain the lubrication effect of the high-frequency operation of the compressor and reduce friction power consumption. At the same time, the circulating refrigeration oil in the air-conditioning system, that is, the oil discharge of the compressor is reduced, and the generation of oil film is reduced, which effectively improves the heat exchange efficiency of the air-conditioning system and further improves the heating energy efficiency of the air-conditioning system.

[0069] like Figure 1 As shown, the rotor drives the control member 3 in the first speed state, and the first speed state is the low frequency operation or medium frequency operation of the compressor. At this time, the rotor rotation rate is low, and the control member 3 driven by the rotor has a low rotation rate. In this state, the control member 3 is limited in the first position by the damping component 4, that is, the control member 3 drives the housing 1 to rotate in the first position. In this state, the oil hole group and the conducting hole are relative to each other, and all the oil hole groups are in an open state, that is, when the compressor is in a low frequency or medium frequency operation state, the oil hole groups are in an open state, maintaining a large oil discharge volume of the compressor, reducing the accumulation of refrigeration oil in the compressor, avoiding the reduction of the effective mass flow rate of the refrigerant, and avoiding reducing the refrigeration capacity of the compressor. It can be understood by those skilled in the art that in the air-conditioning system, the refrigeration oil and the refrigerant together form a mixed fluid, and the mass of the mixed fluid is constant. Therefore, if the refrigeration oil (the oil discharge volume of the compressor) decreases, the refrigerant increases, and if the refrigeration oil increases, the refrigerant decreases.

[0070] By designing the damping component 4, the control component 3 has corresponding position limitations in the high-speed rotation state and the low-speed rotation state, so that the control component 3 can close part of the oil hole group in the high-speed rotation state to reduce the oil discharge of the compressor, that is, through the cooperation of the control component 3 and the damping component 4, the oil discharge of the compressor is cleverly controlled along with the compressor frequency conversion, so that when the compressor is running at medium and low frequencies, the oil discharge amount is not affected, and the refrigerant mass flow rate and the compressor cooling capacity are maintained accordingly. When the compressor is running at high frequency, the oil discharge amount is reduced, and the oil lubrication of the compressor pump body components can be maintained normally, reducing friction loss. At the same time, the amount of refrigeration oil circulating in the air-conditioning system is reduced, and the oil film covering the inner wall of the air-conditioning system pipeline is reduced, which effectively improves the heat exchange efficiency of the air-conditioning system, and further improves the heating energy efficiency of the air-conditioning system, and the APF energy efficiency of the air-conditioning system is not attenuated.

[0071] Optionally, in an implementation of this embodiment, as Figure 1-8 As shown,

[0072] The plurality of oil hole groups and the conducting holes are located on a circle with the same radius; the number of the plurality of first through holes, the plurality of second through holes, and the plurality of oil hole groups is n;

[0073] The plurality of conducting holes include m conducting small holes 301 and one conducting large hole 302, and the circumferential hole length of the conducting large hole 302 is set to be able to conduct nm oil hole groups arranged in sequence in the circumferential direction during the rotation of the control member, where n>m and nm≥2;

[0074] The rotor drives the control member 3 in the first speed state, the control member 3 is limited in the first position by the damping assembly 4, the m small conducting holes 301 are opposite to and connected with the m oil hole groups one by one, the large conducting holes 302 are opposite to and connected with the nm oil hole groups, and the n oil hole groups are all in an open state;

[0075] The rotor drives the control member 3 in the second speed state, and the control member 3 is limited in the second position by the damping assembly 4. The m small conducting holes 301 are staggered with the m oil hole groups one by one, and the large conducting holes 302 are opposite to and connected with the nm oil hole groups. The m oil hole groups are all in a closed state, and the nm oil hole groups are all in an open state.

[0076] In this embodiment, taking n=6 and m=3 as an example, the oil output control component is used for a compressor. During operation, the rotor of the compressor drives the control component 3 to rotate. During this process, the housing 1 rotates along with the rotation of the control component 3, and the housing 1 does not interfere with the rotor. The compressor in the air conditioner discharges a large amount of oil under low-temperature heating conditions. A large amount of oil discharged by the compressor will cause the formation of an oil film, and the oil film generally covers the pipe wall in the air-conditioning system, resulting in a decrease in the heat exchange efficiency of the air-conditioning system. In addition, the oil discharged by the compressor is refrigeration oil, which takes away the heat of the air-conditioning system to a certain extent, further resulting in a decrease in the heating energy efficiency of the air-conditioning system.

[0077] Preferably, the housing 1 can be constructed as a motor rotor baffle in a compressor, or the motor rotor baffle in the compressor can be directly set as a cavity structure as the housing 1 in the oil discharge control assembly. This structure is simple, low-cost, does not rely on an external control module, and enables the control component 3 to effectively control the oil discharge of the compressor.

[0078] The oil outlet control component in this embodiment is as follows: Figure 2As shown, the rotor drives the control member 3 in the second speed state, and the second speed state is the high-frequency operation of the compressor. At this time, the rotor rotates at a high speed, and it drives the control member 3 to rotate at a high speed. In this state, the control member 3 is limited in the second position by the damping component 4, that is, the control member 3 drives the shell 1 to rotate in the second position. In this state, the small conductive hole 301 is staggered with the three oil hole groups, and the large conductive hole 302 is opposite to the three oil hole groups. The three oil hole groups are all in a closed state, and the three oil hole groups are all in an open state. That is, when the compressor is in the high-frequency operation state, among the six oil hole groups, three oil hole groups are in an open state, and three oil hole groups are in a closed state, that is, the oil discharge amount of the compressor is reduced by half, and half of the oil discharge amount can maintain the lubrication effect of the high-frequency operation of the compressor, reduce friction power consumption, and at the same time, the circulating refrigeration oil in the air-conditioning system, that is, the oil discharge of the compressor is reduced, and the generation of oil film is reduced, which effectively improves the heat exchange efficiency of the air-conditioning system and further improves the heating energy efficiency of the air-conditioning system.

[0079] like Figure 1 As shown, the rotor drives the control member 3 in the first speed state, and the first speed state is the low frequency operation or medium frequency operation of the compressor. At this time, the rotor rotation rate is low, and the control member 3 is driven to rotate at a low rate. In this state, the control member 3 is limited in the first position by the damping component 4, that is, the control member 3 drives the housing 1 to rotate in the first position. In this state, the small conductive hole 301 is opposite to the three oil hole groups, and the large conductive hole 302 is opposite to the three oil hole groups. The six oil hole groups are all in an open state, that is, when the compressor is in a low frequency or medium frequency operation state, the oil hole groups are all in an open state, maintaining a large oil discharge volume of the compressor, reducing the accumulation of refrigeration oil in the compressor, avoiding the reduction of the effective mass flow rate of the refrigerant, and avoiding reducing the refrigeration capacity of the compressor. It can be understood by those skilled in the art that in the air-conditioning system, the refrigeration oil and the refrigerant together form a mixed fluid, and the mass of the mixed fluid is constant. Therefore, if the refrigeration oil (the oil discharge volume of the compressor) decreases, the refrigerant increases, and if the refrigeration oil increases, the refrigerant decreases.

[0080] By designing the damping component 4, the control component 3 has corresponding position limitations in the high-speed rotation state and the low-speed rotation state, so that the control component 3 can close part of the oil hole group in the high-speed rotation state to reduce the oil discharge of the compressor, that is, through the cooperation of the control component 3 and the damping component 4, the oil discharge of the compressor is cleverly controlled along with the compressor frequency conversion, so that when the compressor is running at medium and low frequencies, the oil discharge amount is not affected, and the refrigerant mass flow rate and the compressor cooling capacity are maintained accordingly. When the compressor is running at high frequency, the oil discharge amount is reduced, and the oil lubrication of the compressor pump body components can be maintained normally, reducing friction loss. At the same time, the amount of refrigeration oil circulating in the air-conditioning system is reduced, and the oil film covering the inner wall of the air-conditioning system pipeline is reduced, which effectively improves the heat exchange efficiency of the air-conditioning system, and further improves the heating energy efficiency of the air-conditioning system, and the APF energy efficiency of the air-conditioning system is not attenuated.

[0081] Optionally, in an implementation of this embodiment, as Figure 1-3 ,5-8,

[0082] A guide structure is disposed between the housing 1 and the control member 3 to allow both to rotate within the preset angle range.

[0083] Specifically, the guide structure includes a column 6 and a limiting hole 7;

[0085] The limiting hole 7 has a first limiting end 701 and a second limiting end 702 in the relative sliding direction with the column 6; when the rotor drives the control member 3 in a first speed state, the column 6 is located at the first limiting end 701, and the control member 3 is in the first position; when the rotor drives the control member 3 in a second speed state, the column 6 is located at the second limiting end 702, and the control member 3 is in the second position.

[0086] In this embodiment, preferably, the limiting hole 7 is an arc-shaped hole, the first limiting end 701 and the second limiting end 702 are respectively the two ends of the arc-shaped hole, and the limiting column 6 and the limiting hole 7 are both provided with 4 and are arranged along the annular interval;

[0087] When the compressor is running at medium and low frequencies, the limit column 6 is located at the first limit end 701. At this time, the first limit end 701 limits the limit column 6. When the compressor is running at high frequencies, the limit column 6 is located at the second limit end 702, that is, the cooperation between the limit column 6 and the limit hole 7 enables the control component 3 to only be switched between the first position and the second position, thereby making the movement of the control component 3 more stable and the control of the oil discharge amount of the compressor more stable.

[0088] Preferably, the housing 1 includes a housing seat and a housing cover connected to the housing seat, the housing seat forms the first wall 101 and a peripheral side wall 105 connected to the peripheral side of the first wall 101, the housing cover forms the second wall 102, and the housing seat and the housing cover together enclose the cavity 2;

[0089] There is a certain distance between the edge of the control member 3 and the surrounding side wall 105, and this distance forms an installation cavity for installing the damping component 4, which facilitates the installation of the damping component 4 between the control member 3 and the surrounding side wall 105, and the design of the installation cavity makes it easy for the damping component 4 to limit the control member 3.

[0090] Optionally, in an implementation of this embodiment, as Figure 1 , 2 ,5-8,

[0091] The first wall 101 and the second wall 102 are both circular walls;

[0092] The housing 1 further includes a peripheral side wall 105 connected between the first wall 101 and the second wall 102, and the peripheral side wall 105 is an arc surface;

[0093] The control member 3 is a nearly circular plate, and its circumferential side wall includes a first flat arc segment 303 and a second flat arc segment 304 that are oppositely arranged, and the first flat arc segment 303 and the second flat arc segment 304 are symmetrically arranged about the central axis of the control member 3;

[0094] The damping assembly 4 includes a damping block 401 and a damping elastic member 402. A first mounting cavity 501 is formed between the first flat arc segment 303 of the control member 3 and the peripheral side wall 105 of the shell. A second mounting cavity 502 is formed between the second flat arc segment 304 of the control member 3 and the peripheral side wall 105 of the shell. The damping block 401 is installed in the first mounting cavity 501, and the damping elastic member 402 is installed in the second mounting cavity 502.

[0095] Preferably, the control member 3 is a nearly circular plate body, and its circumferential side walls include a first flat arc segment 303 and a second flat arc segment 304 that are relatively arranged, a first circular arc segment opposite to the first flat arc segment 303, and a second circular arc segment opposite to the second flat arc segment 304. The first flat arc segment 303, the first circular arc segment, the second flat arc segment 304 and the second circular arc segment are sequentially connected to form a nearly circular plate body.

[0096] The term "nearly circular" is usually used to refer to a geometric shape that is close to a circle, but may not be a perfect circle. In geometry, a nearly circular figure may be an ellipse, an oblate, or another shape similar to a circle. Although these shapes are somewhat different from a circle, they look similar in appearance.

[0097] In this embodiment, when the compressor is running at medium and low frequencies, the rotation rate of the rotor is relatively low, which drives the control member 3 to rotate at a relatively low rate. In this state, the centrifugal force on the control member 3 is relatively small, and it is unable to overcome the resistance of the first damping surface 4011 in the damping block 401 and the pulling force of the damping elastic member 402. As a result, the control member 3 is jointly limited in the first position by the damping block 401 and the damping elastic member 402. The first position corresponds to the small conductive hole 301 being opposite to the three oil hole groups, and the large conductive hole 302 being opposite to the three oil hole groups, and all six oil hole groups are in an open state. As a result, when the compressor is running at a low or medium frequency, the oil hole groups are all in an open state, thereby maintaining a relatively large oil discharge volume of the compressor.

[0098] When the compressor is running at high frequency, the rotor rotates at a high speed, which drives the control member 3 to rotate at a high speed. In this state, the centrifugal force on the control member 3 is large, which can overcome the resistance of the first damping surface 4011 in the damping block 401 and the pulling force of the damping elastic member 402. As a result, the control member 3 and the second damping surface 4012 are abutted against the damped component 4 and limited in the second position. At this time, the second tensile force on the damping elastic member 402 is greater than the first tensile force on the control member 3 when the compressor is running at medium and low frequencies. The second position corresponds to the small conductive hole 301 being staggered with the three oil hole groups, and the large conductive hole 302 being opposite to the three oil hole groups. The three oil hole groups are all in a closed state, and the three oil hole groups are all in an open state. As a result, when the compressor is running at high frequency, three of the six oil hole groups are open and three are closed, thereby reducing the oil discharge of the compressor. When the compressor switches from high-frequency operation to medium-low frequency operation, the centrifugal force on the control component 3 returns to a smaller state. At this time, under the pull-back action of the damping elastic component 402, the control component 3 is reset to the first position again, thereby achieving that during the operation of the compressor, the oil discharge volume is always in a dynamic adjustment process, effectively maintaining the overall operating energy efficiency of the compressor.

[0099] Optionally, in an implementation of this embodiment, as Figure 1-8 As shown,

[0100] The small conductive hole 301 is a small arc-shaped hole, and the large conductive hole 302 is a large arc-shaped hole;

[0101] When the rotor drives the control member 3 at the first speed state, the three small arc holes correspond to three of the oil hole groups one by one, one arc hole corresponds to all of the other three oil hole groups, and the six oil hole groups are all in an open state;

[0102] When the rotor drives the control member 3 at the second speed state, the three small arc holes are staggered with three of the oil hole groups, and the three oil hole groups are all in a closed state, and one arc hole corresponds to all of the other three oil hole groups, and the other three oil hole groups are all in an open state.

[0103] In this embodiment, n=6, m=3, and the small conductive hole 301 is designed to be composed of three small arc holes and the large conductive hole 302 is designed to be composed of one arc hole, so that when the compressor is running at high frequency, the control member 3 is limited in the second position by the damping component 4, that is, the control member 3 drives the shell 1 to rotate in the second position. In this state, the three small arc holes are staggered with three of the oil hole groups, and the three oil hole groups are all in a closed state. One arc hole corresponds to all the other three oil hole groups, and the other three oil hole groups are all in an open state, so that when the compressor is running at high frequency, 3 of the 6 oil hole groups are in an open state and 3 are in a closed state, that is, the oil discharge of the compressor is reduced by half, and half of the oil discharge can maintain the lubrication effect of the high-frequency operation of the compressor, reduce friction power consumption, and at the same time, the circulating refrigeration oil in the air-conditioning system, that is, the oil discharge of the compressor is reduced, and the generation of oil film is reduced, which effectively improves the heat exchange efficiency of the air-conditioning system and further improves the heating energy efficiency of the air-conditioning system.

[0104] It is also convenient to realize that when the compressor is running at medium and low frequencies, the control member 3 is limited in the first position by the damping assembly 4, that is, the control member 3 drives the shell 1 to rotate in the first position. In this state, the three small arc holes correspond one-to-one to three of the oil hole groups, and the three oil hole groups are all in an open state. One arc hole corresponds to all the other three oil hole groups, and the other three oil hole groups are all in an open state. When the compressor is running at medium and low frequencies, the six oil hole groups are all in an open state, maintaining a large oil discharge volume of the compressor, reducing the accumulation of refrigerant oil in the compressor, avoiding a reduction in the effective mass flow rate of the refrigerant, and avoiding a reduction in the cooling capacity of the compressor.

[0105] Optionally, in an implementation of this embodiment, as Figure 5 , 11 As shown,

[0106] The damping block 401 includes a connecting surface located on one side of the damping block and a first damping surface 4011 and a second damping surface 4012 located on the other side of the damping block;

[0107] The connecting surface faces the circumferential side wall 105 of the shell and acts together with the circumferential side wall of the shell, the first damping surface 4011 and the second damping surface 4012 face the control member and a protrusion 4013 facing the control member is formed therebetween; when the control member 3 is driven by the rotor and is in a first speed state, the first flat arc segment 303 of the control member 3 abuts against the first damping surface 4011 and the control member 3 is limited in the first position; when the control member 3 is driven by the rotor and is in a second speed state, the first flat arc segment 303 of the control member 3 abuts against the second damping surface 4012 and the control member 3 is limited in the second position;

[0108] The two ends of the damping elastic member 402 are respectively connected to the peripheral side wall 105 and the control member 3. When the control member 3 is driven by the rotor and is in a first speed state, the damping elastic member 402 has a first tensile force. When the control member 3 is driven by the rotor and is in a second speed state, the damping elastic member 402 has a second tensile force, and the second tensile force is greater than the first tensile force.

[0109] In this embodiment, the protrusion 4013 is located between the first damping surface 4011 and the second damping surface 4012, and plays a role in relative positioning of the control member 3. That is, when the control member 3 is located in the first position or the second position, the setting of the protrusion 4013 can keep the position of the control member 3 stable in this state.

[0110] Optionally, in an implementation of this embodiment, as Figure 3 As shown,

[0111] An axial hole 8 is formed at the center of the first wall 101 and the second wall 102 . A shaft sleeve 9 opposite to the axial hole 8 is disposed at the center of the control member 3 . The rotor is transmission-connected to the shaft sleeve 9 and passes through the axial hole 8 .

[0112] In this embodiment, the arrangement of the shaft sleeve 9 facilitates direct transmission connection between the rotor in the compressor and the shaft sleeve 9, so that the control member 3 is directly driven by the rotor, and the arrangement of the shaft hole 8 facilitates direct penetration of the rotor, and the rotor itself has no connection relationship with the shaft hole 8 to avoid interference between the rotor and the housing 1, so that the housing 1 rotates completely with the rotation of the control member 3, thereby achieving the change of the relative position between the control member 3 and the housing 1 with the change of the rotation speed of the control member 3.

[0113] Optionally, in an implementation of this embodiment, as Fig.10 As shown,

[0114] The oil output control component is used for a motor rotor or a compressor rotor.

[0115] The housing 1 is designed as a shroud of the rotor or the shroud of the rotor is designed as the housing 1 .

[0116] This construction method makes the motor rotor or compressor rotor structure simple, and when the compressor is running at a low frequency, under the action of the damping component 4, the six oil holes of the rotor are in a conducting state, ensuring oil discharge, reducing the accumulation of refrigeration oil in the compressor, causing the effective mass flow of the refrigerant to decrease, thereby reducing the refrigeration capacity of the compressor. When the compressor is running at a high frequency, under the action of a large centrifugal force, the centrifugal force is greater than the damping force of the damping component 4, the control member 3 rotates clockwise in a small range, and the three oil holes near one end of the main balance block 10 are blocked, and the oil hole on the side of the secondary balance block 11 remains open, reducing high-frequency oil discharge, ensuring the lubrication of the high-frequency operation of the compressor, reducing friction power consumption, and at the same time, the circulating refrigeration oil of the two devices is reduced, reducing the generation of lubricating oil film of the two devices, improving heat exchange efficiency, and improving system capacity. The oil discharge amount of the compressor operation is effectively controlled, thereby affecting the APF of the system, and to a certain extent maintaining the compressor energy efficiency without attenuation after the shell is shortened.

[0117] Embodiment 2

[0118] like Fig. 9 , 10 As shown, this embodiment provides a compressor, including:

[0119] The oil outlet control assembly in the first embodiment;

[0120] The rotor 12, the oil outlet control assembly is arranged on a side wall of the rotor 12, the rotor 12 is provided with an oil hole opposite to the oil hole group, the rotor 12 and the oil outlet control assembly together constitute the rotor, the oil outlet control assembly is provided with a secondary balancing block 11, and the secondary balancing block 11 is close to the conducting large hole 302, and the main balancing block 10 is provided on the side wall of the rotor 12 opposite to the oil outlet control assembly.

[0121] In the existing air-conditioning system, with the increasing demand for efficiency improvement and cost reduction, the requirements for compressors are getting higher and higher. In some cases, due to limited installation space, there is a situation where the air-conditioning shell is shortened. In this case, the corresponding upper chamber volume of the motor is reduced, resulting in the compressor emitting more oil under the same amount of work conditions. The overall system energy efficiency APF of the air-conditioning is much different from that under low-temperature heating conditions when the shell is not shortened. The compressor provided in this embodiment is provided with an oil discharge control component on the rotor 12 in the compressor to control the oil discharge amount of the compressor under high-frequency and medium-low frequency operation conditions. The oil discharge control component controls the amount of oil flowing through the rotor oil hole at one end of the main balance block 10, that is, the oil discharge control component in the first embodiment is on the rotor 12, and the whole is similar to a rotor baffle, wherein the large conductive hole 302 is close to the auxiliary balance block 11, so that the oil hole at one end of the auxiliary balance block 11 is always open, and the oil discharge rate is adjusted by the relative or staggered conduction of the small conductive hole 301 close to one end of the main balance block 10 and the corresponding oil hole group. When the compressor is running at low frequency, under the action of the damping component 4, the six oil holes of the rotor are ensured to be in a conducting state, ensuring oil discharge, reducing the accumulation of refrigeration oil in the compressor, causing the effective mass flow of the refrigerant to decrease, thereby reducing the refrigeration capacity of the compressor. When the compressor is running at high frequency, under the action of a large centrifugal force, the centrifugal force is greater than the damping force of the damping component 4, and the control member 3 rotates clockwise in a small range, and the three oil holes near one end of the main balance block 10 are blocked, and the oil holes on the side of the secondary balance block 11 remain open, reducing high-frequency oil discharge, ensuring the lubrication of the high-frequency operation of the compressor, reducing friction power consumption, and at the same time reducing the circulating refrigeration oil of the two devices, reducing the generation of lubricating oil film of the two devices, improving heat exchange efficiency, and improving system capacity. The oil discharge volume of the compressor operation is effectively controlled, thereby affecting the APF of the system, and to a certain extent maintaining the compressor energy efficiency without attenuation after the shell is shortened.

[0122] Embodiment 3

[0123] This embodiment provides an air conditioner, including:

[0124] The oil output control component in Example 1, or the compressor in Example 2.

[0125] By designing the damping component 4, the control component 3 has corresponding position limitations in the high-speed rotation state and the low-speed rotation state, so that the control component 3 can close part of the oil hole group in the high-speed rotation state to reduce the oil discharge of the compressor, that is, through the cooperation of the control component 3 and the damping component 4, the oil discharge of the compressor is cleverly controlled along with the compressor frequency conversion, so that when the compressor is running at medium and low frequencies, the oil discharge amount is not affected, and the refrigerant mass flow rate and the compressor cooling capacity are maintained accordingly. When the compressor is running at high frequency, the oil discharge amount is reduced, and the oil lubrication of the compressor pump body components can be maintained normally, reducing friction loss. At the same time, the amount of refrigeration oil circulating in the air-conditioning system is reduced, and the oil film covering the inner wall of the air-conditioning system pipeline is reduced, which effectively improves the heat exchange efficiency of the air-conditioning system, and further improves the heating energy efficiency of the air-conditioning system, and the APF energy efficiency of the air-conditioning system is not attenuated.

[0126] In summary, the ingenious design of the oil outlet control component is:

[0127] First, by designing the damping component, the control component has corresponding position limitations in high-speed rotation and low-speed rotation, so that the control component can close part of the oil hole group in high-speed rotation to reduce the oil discharge of the compressor, that is, the oil discharge of the compressor is cleverly controlled along with the frequency conversion of the compressor through the cooperation of the control component and the damping component, so that when the compressor is running at medium and low frequencies, the oil discharge amount is not affected, and the refrigerant mass flow rate and the compressor cooling capacity are maintained accordingly. When the compressor is running at high frequency, the oil discharge amount is reduced, and the oil lubrication of the compressor pump body components can be maintained normally, reducing friction loss. At the same time, the amount of refrigeration oil circulating in the air-conditioning system is reduced, and the oil film covering the inner wall of the air-conditioning system pipeline is reduced, which effectively improves the heat exchange efficiency of the air-conditioning system, and further improves the heating energy efficiency of the air-conditioning system, and the APF energy efficiency of the air-conditioning system is not attenuated.

[0128] Second, the damping component is designed as a damping block combined with a damping elastic member. When the compressor is running at medium and low frequencies, the rotation speed of the control member driven by it is relatively low, and the centrifugal force on the control member is relatively small, which cannot overcome the resistance in the damping block and the tension of the damping elastic member. Therefore, the control member is limited to the first position by the damping block and the damping elastic member. The first position corresponds to the oil hole group being in an open state, so that the oil hole group is in an open state when the compressor is running at low or medium frequencies, and the compressor maintains a large oil discharge. When the compressor is running at high frequencies, the rotation speed of the control member driven by it is relatively high, and the centrifugal force on the control member is relatively large, which can overcome the resistance of the damping block and the tension of the damping elastic member. Therefore, the control member is limited to the second position by the damping component. The second position corresponds to a plurality of oil hole groups, half of which are open and half of which are closed, so that the compressor can reduce the oil discharge when it is running at high frequencies. When the compressor switches from high-frequency operation to medium- and low-frequency operation, the centrifugal force on the control member returns to a smaller state. At this time, under the pullback action of the damping elastic member, the control member is reset to the first position again. In this way, the oil discharge volume is always in a dynamic adjustment process during the operation of the compressor, effectively maintaining the overall operating energy efficiency of the compressor.
