Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a compressor and an air conditioner. Background Art

[0002] The oil discharge volume of the rotary compressor not only has a vital impact on the performance of the air-conditioning system, but also determines the amount of oil stored in the compressor, which directly affects the lubrication status of the compressor components. Therefore, this indicator is an important item in the evaluation of the compressor unit.

[0003] If the compressor discharges oil at a high rate, the oil circulation efficiency will be reduced, resulting in unstable machine operation. It will also increase friction among machine parts, thereby damaging them. Therefore, how to reduce oil discharge becomes an urgent problem to be solved. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] In view of this, in the first aspect, the utility model proposes a compressor, comprising: a shell, the shell having an air inlet and an air outlet; a compression part, located in the shell, the compression part is used to compress the refrigerant, the compression part has a compression chamber, and the compression chamber is connected to the air inlet; a stator, located in the shell; a rotor, coaxially arranged with the stator, the stator is sleeved on the rotor, the compression part is located on one axial side of the rotor, and the air outlet is located on the other axial side of the rotor; a rotating shaft, connected to the rotor and the compression part, the rotating shaft rotates synchronously with the rotor; a spoiler, connected to a side of the rotor away from the compression part, the spoiler is distributed along the circumference of the rotor, the spoiler is provided with a plurality of air holes, and the plurality of air holes are distributed along the circumference of the spoiler.

[0006] The stator and the rotor cooperate with each other so that the rotor can rotate relative to the stator. The rotor drives the compression part to operate through the rotating shaft. The refrigerant can enter the compression chamber through the air inlet. The refrigerant can be compressed when the compression part is in operation.

[0007] When the rotor rotates, the spoiler rotates with the rotor, and the refrigerant discharged from the compression part flows along the rotor to the other side of the rotor in the axial direction. The spoiler can disturb the gas near the axial end face of the rotor, thereby forming a disturbed airflow near the axial end face of the rotor. Driven by the disturbed airflow, part of the refrigerant flowing out of the rotor will flow radially toward the rotor. Since the vents are provided on the spoiler, the refrigerant can continue to flow toward the side wall of the shell through the vents. In the case where no spoiler is provided, the refrigerant flowing on the end face of the rotor will continue to flow toward the axial direction of the rotor to the air outlet. By adding a spoiler to disturb the refrigerant, the refrigerant first flows to the side of the shell and then flows to the air outlet. By increasing the distance and duration of the refrigerant flowing to the air outlet, more oil can be separated from the refrigerant, and the amount of oil driven by the refrigerant to the compressor will be reduced, thereby improving the circulation efficiency of the oil and ensuring the stable operation of the machine. The oil plays a role of lubrication and cooling in the machine. The above method reduces the amount of oil discharge, avoids increased friction of machine parts, and thus avoids damage to machine parts. Moreover, by reducing the amount of oil discharged, the probability of the heat exchanger, evaporator and associated pipelines being covered by oil film can be reduced, avoiding affecting the heat exchange capacity of the machine.

[0008] In addition, the compressor in the above technical solution provided by the utility model may also have the following additional technical features:

[0009] In some technical solutions, optionally, the spoiler includes: a mounting portion connected to a side of the rotor away from the compression portion; a spoiler portion connected to the mounting portion, the spoiler portion extending in a direction away from the rotor compared to the mounting portion, and the vent hole is arranged on the spoiler portion.

[0010] In order to install the spoiler on the rotor, a part of the spoiler needs to be fitted to the axial end face of the rotor, and in order to disturb the refrigerant, another part of the spoiler needs to be extended in a direction away from the rotor. Therefore, the mounting portion can be fitted to the end face of the rotor to ensure that the spoiler can be stably fixed to the rotor, the end of the spoiler is connected to the mounting portion, and there is an angle between the spoiler and the mounting portion, so that the spoiler is tilted on the axial end face of the rotor. When the vent hole is set on the spoiler, the disturbed refrigerant can pass through the spoiler, so that the refrigerant flows to the side of the shell.

[0011] In some technical solutions, optionally, the first end of the spoiler is connected to the mounting portion, and along the axial direction of the rotor, the distance between the second end of the spoiler and the rotor is L1, and the distance between the center line of the vent and the rotor is L2, and L1 and L2 satisfy 0.4L1≤L2≤0.6L1.

[0012] When L1 and L2 satisfy 0.4L1≤L2≤0.6L1, the vent is closer to the center of the spoiler. If the center of the vent is too close to the rotor, the refrigerant will have difficulty entering the vent, causing the spoiler to block the refrigerant flowing to the side of the shell. If the center of the vent is too close to the second end of the spoiler, the stiffness of the spoiler will be reduced, causing the spoiler to be easily deformed. Therefore, placing the center of the vent close to the center of the spoiler can ensure that the refrigerant can pass through the vent smoothly, and can also ensure the stiffness of the spoiler, preventing the spoiler from deforming when rotating.

[0013] In some technical solutions, optionally, there are multiple connecting lines on the flow cross-section of the vent hole, the connecting lines pass through the center line, and the length of the longest connecting line among the multiple connecting lines is set to L3, and L1 and L3 satisfy 0.3L1≤L3≤0.7L1.

[0014] In order to ensure that the refrigerant can pass through the vent hole smoothly, it is necessary to ensure that the vent hole has a sufficient flow cross-sectional area. The maximum length dimension in the flow cross section of the vent hole can be used to reflect the flow cross-sectional area of ​​the vent hole. If the maximum length of the line passing through the center line of the vent hole is too small, it means that the flow cross-sectional area of ​​the vent hole is too small, and the refrigerant is difficult to pass through the vent hole smoothly. If the maximum length of the line passing through the center line of the vent hole is too large, it means that the flow cross-sectional area of ​​the vent hole is too large, resulting in a low structural strength of the spoiler.

[0015] When L1 and L3 satisfy 0.3L1≤L3≤0.7L1, the flow cross-sectional area of ​​the vent hole is moderate, which will neither hinder the flow of the refrigerant nor easily reduce the structural strength of the spoiler, thereby avoiding deformation of the spoiler.

[0016] In some technical solutions, optionally, a plurality of mounting holes are provided on the mounting portion, and the plurality of mounting holes are distributed along the circumference of the mounting portion; the compressor further includes: a locking member, which passes through the mounting hole and is connected to the rotor to lock the mounting portion to the rotor.

[0017] A plurality of mounting holes are arranged in the circumferential direction of the mounting portion, so that a plurality of fixing points are formed in the circumferential direction of the mounting portion, thereby ensuring that the mounting portion can be stably locked on the rotor.

[0018] In some technical solutions, optionally, the compressor further includes: a balancing block connected to the mounting portion.

[0019] When the balancing block is installed on the mounting part, the imbalance of the rotor can be effectively reduced when it runs at high speed, avoiding problems such as mechanical vibration, excessive noise, premature bearing failure caused by the imbalance, and ensuring that the compressor has good performance and a long service life.

[0020] In some technical solutions, optionally, the distance between the side of the balancing weight facing away from the rotor and the rotor is L4, and the distance between the second end of the spoiler and the rotor is greater than L4.

[0021] With the circumferential end surface of the rotor as a reference plane, the spoiler is higher than the balancing block. Within this range, the balancing block can stably reduce the unbalance effect of the rotor during operation and ensure the stable operation of the rotor.

[0022] In some technical solutions, optionally, a flow hole is provided in the axial direction of the rotor, the flow hole passes through both axial ends of the rotor, and the flow hole is used for allowing the refrigerant to pass through; an avoidance hole is provided on the spoiler, the rotor has an axis, and the distance from the inner wall of the avoidance hole to the axis is greater than the distance from the inner wall of the flow hole to the axis.

[0023] A flow hole is arranged on the rotating shaft, and the flow hole penetrates the rotor along the axial direction of the rotor. The refrigerant discharged from the compression part can flow along the flow hole to the other axial side of the rotor. When the refrigerant flows out of the flow hole, the spoiler drives the refrigerant to flow to the side of the shell.

[0024] The spoiler is arranged on the other axial side of the rotor. In order to avoid the spoiler from blocking the flow hole, it is necessary to set the radial dimension of the inner wall of the avoidance hole to be larger than the radial dimension of the outermost edge of the flow hole to prevent the spoiler from blocking the upward refrigerant.

[0025] In some technical solutions, optionally, the flow cross-sectional area of ​​the flow hole is S1, the sum of the flow cross-sectional areas of the plurality of vent holes is S2, and S1 and S2 satisfy 0.7≤S2 / S1≤1.3.

[0026] The sum of the flow cross-sectional areas of multiple vents needs to be correlated with the flow cross-sectional area of ​​the flow holes. If the flow cross-sectional area of ​​the flow holes is much larger than the sum of the flow cross-sectional areas of multiple vents, most of the refrigerant will be unable to pass through the vents. If the flow cross-sectional area of ​​the flow holes is much smaller than the sum of the flow cross-sectional areas of multiple vents, it means that the flow cross-sectional area of ​​the vents is too large, which will damage the structure of the spoiler, or the material of the spoiler is used too much.

[0027] When S1 and S2 satisfy 0.7≤S2 / S1≤1.3, the flow cross-sectional area of ​​the flow hole and the sum of the flow cross-sectional areas of multiple ventilation holes match each other, which can not only ensure that the refrigerant can pass through the ventilation holes smoothly, but also avoid the cross-sectional area of ​​the ventilation holes being too large to damage the structural strength of the spoiler, and can also save the material usage of the spoiler.

[0028] In a second aspect, the utility model provides an air conditioner, comprising: a compressor as in the first aspect.

DETAILED DESCRIPTION

[0039] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0041] Refer to the following Figures 1 to 6A compressor and an air conditioner provided according to some embodiments of the utility model are described.

[0042] Combination Figure 1 and Figure 2 As shown, in an embodiment of the present utility model, a compressor is proposed, comprising: a housing 100, a compression unit 200, a stator 300, a rotor 400, a rotating shaft 500 and a spoiler 600, the housing 100 has an air inlet 110 and an air outlet 120, the compression unit 200 is located in the housing 100, the compression unit 200 is used to compress the refrigerant, the compression unit 200 has a compression chamber 260, and the compression chamber 260 is connected to the air inlet 110. The stator 300 is located in the housing 100, the rotor 400 is coaxially arranged with the stator 300, the stator 300 is sleeved on the rotor 400, and the compression unit 200 is located in the axial direction of the rotor 400 ( Figure 1 The arrow at a in the figure points to one side of the rotor 400 in the axial direction, and the air outlet 120 is located on the other side of the rotor 400 in the axial direction. The rotating shaft 500 is connected to the rotor 400 and the compression part 200, and the rotating shaft 500 rotates synchronously with the rotor 400. The spoiler 600 is connected to the side of the rotor 400 away from the compression part 200, and the spoiler 600 is arranged along the circumferential direction ( Figure 4 The arrow at b in the figure points to the circumferential direction of the rotor 400 . The spoiler 600 is provided with a plurality of vent holes 610 , which are distributed along the circumferential direction of the spoiler 600 .

[0043] The stator 300 and the rotor 400 cooperate with each other so that the rotor 400 can rotate relative to the stator 300. The rotor 400 drives the compression unit 200 to operate through the rotating shaft 500. The refrigerant can enter the compression chamber 260 through the air inlet 110. The refrigerant can be compressed when the compression unit 200 is in operation.

[0044] When the rotor 400 rotates, the spoiler 600 rotates with the rotor 400, and the refrigerant discharged from the compression part 200 flows along the rotor 400 to the other axial side of the rotor 400. The spoiler 600 can disturb the gas near the axial end face of the rotor 400, thereby forming a disturbed airflow near the axial end face of the rotor 400. Driven by the disturbed airflow, a part of the refrigerant flowing out of the rotor 400 will flow in the radial direction of the rotor 400. Since the vent 610 is provided on the spoiler 600, the refrigerant can continue to flow to the side wall of the housing 100 through the vent 610. In the case where the spoiler 600 is not provided, the refrigerant flowing on the end face of the rotor 400 will continue to flow to the outlet 120 in the axial direction of the rotor 400. By adding the spoiler 600 to disturb the refrigerant, the refrigerant first flows to the side of the housing 100, and then flows to the outlet 120. By increasing the distance and duration of the refrigerant flowing to the air outlet 120, more oil can be separated from the refrigerant, and the amount of oil driven by the compressor by the refrigerant will be reduced, thereby improving the circulation efficiency of the oil and ensuring the stable operation of the machine. The oil plays a role of lubrication and cooling in the machine. By reducing the amount of oil discharged in the above manner, the friction of machine parts is avoided to increase, thereby avoiding damage to machine parts. In addition, by reducing the amount of oil discharged, the probability of the heat exchanger, evaporator and auxiliary pipelines being covered by the oil film can be reduced, avoiding affecting the heat exchange capacity of the machine.

[0045] The vent holes 610 are evenly arranged on the spoiler 600 to facilitate the refrigerant rushing out of the rotor 400 to flow through the vent holes 610 under the action of centrifugal force.

[0046] Figure 5 The middle is a schematic diagram of the flow of the refrigerant when the spoiler 600 is not provided on the rotor 400. The refrigerant flows upward in a relatively concentrated manner. Figure 6 4 is a schematic diagram of the flow of the refrigerant when the spoiler 600 is provided on the rotor 400 , and the refrigerant is more distributed in the radial direction of the rotor 400 .

[0047] The compression part 200 includes: a piston 210, an upper bearing 220, a lower bearing 230, a cylinder 240 and a muffler 250. The rotating shaft 500 is connected to the piston 210. The muffler 250, the upper bearing 220 and the lower bearing 230 are sleeved on the rotating shaft 500. The compression part 200 realizes the compressor's compression suction, compression, exhaust and silencing process of the refrigerant. The housing 100 includes a sealed housing 130 and a main housing 140. The sealed housing 130 and the main housing 140 wrap the compression part 200 and the electric component. The electric component includes a rotor 400 and a stator 300.

[0048] The compressor further includes a liquid reservoir 900, which is located outside the housing 100. The muffler 250 is connected to the air inlet 110. The liquid reservoir 900 is used for lubricating oil separation and preventing liquid hammer from occurring in the compressor.

[0049] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the spoiler 600 includes: a mounting portion 620 and a spoiler portion 630, the mounting portion 620 is connected to a side of the rotor 400 that is away from the compression portion 200, the spoiler portion 630 is connected to the mounting portion 620, the spoiler portion 630 extends in a direction away from the rotor 400 compared to the mounting portion 620, and the vent 610 is provided on the spoiler portion 630.

[0050] In order to install the spoiler 600 to the rotor 400, a part of the spoiler 600 needs to be attached to the axial end face of the rotor 400, and in order to disturb the refrigerant, another part of the spoiler 600 needs to be extended in a direction away from the rotor 400. Therefore, the mounting portion 620 can be attached to the end face of the rotor 400 to ensure that the spoiler 600 can be stably fixed to the rotor 400, the end of the spoiler 630 is connected to the mounting portion 620, and there is an angle between the spoiler 630 and the mounting portion 620, so that the spoiler 630 is tilted on the axial end face of the rotor 400, and when the vent 610 is set on the spoiler 630, the disturbed refrigerant can pass through the spoiler 630, so that the refrigerant flows to the side of the housing 100.

[0051] The mounting portion 620 and the spoiler portion 630 form an L-shaped structure, and evenly distributed vent holes 610 are arranged on the side of the L-shaped structure.

[0052] Combination Figure 2 and Figure 3 As shown, in some embodiments, optionally, the first end of the spoiler 630 is connected to the mounting portion 620, and along the axial direction of the rotor 400, the distance between the second end of the spoiler 630 and the rotor 400 is L1, and the distance between the center line d of the vent 610 and the rotor 400 is L2, and L1 and L2 satisfy 0.4L1≤L2≤0.6L1.

[0053] When L1 and L2 satisfy 0.4L1≤L2≤0.6L1, the vent hole 610 is relatively close to the center of the spoiler 630. If the center of the vent hole 610 is too close to the rotor 400, the refrigerant will have difficulty entering the vent hole 610, causing the spoiler 630 to block the refrigerant flowing to the side of the housing 100. If the center of the vent hole 610 is too close to the second end of the spoiler 630, the rigidity of the spoiler 630 will be reduced, causing the spoiler 630 to be easily deformed. Therefore, placing the center of the vent hole 610 close to the center of the spoiler 630 can ensure that the refrigerant can pass through the vent hole 610 smoothly, and can also ensure the rigidity of the spoiler 630, and prevent the spoiler 630 from being deformed when rotating.

[0054] Combination Figure 2 and Figure 3 As shown, in some embodiments, optionally, there are multiple connecting lines on the flow section of the vent 610, and the connecting lines pass through the center line d. The length of the longest connecting line among the multiple connecting lines is set to L3, and L1 and L3 satisfy 0.3L1≤L3≤0.7L1.

[0055] In order to ensure that the refrigerant can smoothly pass through the vent hole 610, it is necessary to ensure that the vent hole 610 has a sufficient flow cross-sectional area. The maximum length dimension in the flow cross section of the vent hole 610 can be used to reflect the flow cross-sectional area of ​​the vent hole 610. If the maximum length of the line passing through the center line d of the vent hole 610 is too small, it means that the flow cross-sectional area of ​​the vent hole 610 is too small, and the refrigerant is difficult to smoothly pass through the vent hole 610. If the maximum length of the line passing through the center line d of the vent hole 610 is too large, it means that the flow cross-sectional area of ​​the vent hole 610 is too large, resulting in a low structural strength of the spoiler 630.

[0056] When L1 and L3 satisfy 0.3L1≤L3≤0.7L1, the flow cross-sectional area of ​​the vent hole 610 is moderate, which will neither hinder the flow of the refrigerant nor easily reduce the structural strength of the spoiler 630, thereby avoiding deformation of the spoiler 630.

[0057] In some embodiments, optionally, a plurality of mounting holes 621 are provided on the mounting portion 620, and the plurality of mounting holes 621 are arranged along the circumference of the mounting portion 620 ( Figure 4 The arrow pointing at b in the figure can also be used to indicate the circumferential distribution of the mounting portion 620. The compressor further includes a locking member 700, which passes through the mounting hole 621 and is connected to the rotor 400 to lock the mounting portion 620 to the rotor 400.

[0058] A plurality of mounting holes 621 are arranged in the circumferential direction of the mounting portion 620 , so that a plurality of fixing points are formed in the circumferential direction of the mounting portion 620 , thereby ensuring that the mounting portion 620 can be stably locked on the rotor 400 .

[0059] Illustratively, the mounting holes 621 are used to fasten the spoiler 600 and the rotor 400 with screws or rivets.

[0060] like Figure 1 As shown, in some embodiments, optionally, the compressor further includes: a balancing block 800 , and the balancing block 800 is connected to the mounting portion 620 .

[0061] When the balancing block 800 is assembled on the mounting portion 620, the rotor 400 can effectively reduce imbalance when running at high speed, avoid problems such as mechanical vibration, excessive noise, and premature bearing failure caused by imbalance, and ensure that the compressor has good performance and a long service life.

[0062] like Figure 1As shown, in some embodiments, optionally, the distance between the side of the balancing weight 800 facing away from the rotor 400 and the rotor 400 is L4, and the distance between the second end of the spoiler 630 and the rotor 400 is greater than L4.

[0063] Taking the circumferential end surface of the rotor 400 as the reference plane, the spoiler 630 is higher than the balancing block 800 . Within this range, the balancing block 800 can stably reduce the unbalance effect of the rotor 400 during operation, thereby ensuring the stable operation of the rotor 400 .

[0064] Combination Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, optionally, a through hole 410 is provided in the axial direction of the rotor 400, and the through hole 410 runs through both axial ends of the rotor 400, and the through hole 410 is used for the refrigerant to pass through. The spoiler 600 is provided with an avoidance hole 622, and the rotor 400 has an axis c, and the distance between the inner wall of the avoidance hole 622 and the axis c is greater than the distance between the inner wall of the through hole 410 and the axis c.

[0065] A flow hole 410 is provided on the rotating shaft 500 , and the flow hole 410 penetrates the rotor 400 along the axial direction of the rotor 400 . The refrigerant discharged from the compression part 200 can flow along the flow hole 410 to the other axial side of the rotor 400 . When the refrigerant flows out of the flow hole 410 , the spoiler 600 drives the refrigerant to flow toward the side of the shell 100 .

[0066] The spoiler 600 is arranged on the other axial side of the rotor 400. In order to avoid the spoiler 600 from blocking the flow hole 410, it is necessary to set the radial dimension of the inner wall of the avoidance hole 622 larger than the radial dimension of the outermost edge of the flow hole 410 to prevent the spoiler 600 from blocking the upward refrigerant.

[0067] Combination Figure 2 and Figure 4 As shown, in some embodiments, optionally, the flow cross-sectional area of ​​the flow hole 410 is S1, the sum of the flow cross-sectional areas of the plurality of vent holes 610 is S2, and S1 and S2 satisfy 0.7≤S2 / S1≤1.3.

[0068] The sum of the flow cross-sectional areas of the multiple air holes 610 needs to be associated with the flow cross-sectional area of ​​the flow hole 410. If the flow cross-sectional area of ​​the flow hole 410 is much larger than the sum of the flow cross-sectional areas of the multiple air holes 610, most of the refrigerant will not be able to pass through the air holes 610. If the flow cross-sectional area of ​​the flow hole 410 is much smaller than the sum of the flow cross-sectional areas of the multiple air holes 610, it means that the flow cross-sectional area of ​​the air hole 610 is too large, which will damage the structure of the spoiler 600, or the material usage of the spoiler 600 is too large.

[0069] When S1 and S2 satisfy 0.7≤S2 / S1≤1.3, the flow cross-sectional area of ​​the flow hole 410 and the sum of the flow cross-sectional areas of the multiple ventilation holes 610 match each other, which can not only ensure that the refrigerant can pass through the ventilation holes 610 smoothly, but also avoid the cross-sectional area of ​​the ventilation holes 610 being too large to damage the structural strength of the spoiler 600, and can also save the material usage of the spoiler 600.

[0070] Figure 4 In the figure, the shaded area on a through hole 410 is S1. Figure 3 In FIG. 1 , the shaded area at the mark 610 is the flow cross-sectional area of ​​one vent hole 610 , and the sum of the flow cross-sectional areas of multiple vent holes 610 is S2 .

[0071] By matching the area of ​​the vent hole 610 with the area of ​​the flow hole 410, the purpose of reducing oil discharge can be better achieved.

[0072] In an embodiment of the present utility model, an air conditioner is proposed, comprising: a compressor as in any of the above embodiments, and can achieve the same technical effects, which will not be described in detail here.

[0073] The spoiler 600 can disturb the gas near the axial end face of the rotor 400, thereby forming a disturbed airflow near the axial end face of the rotor 400. Driven by the disturbed airflow, a portion of the refrigerant flowing out of the rotor 400 will flow radially of the rotor 400. Since the vent 610 is provided on the spoiler 600, the refrigerant can continue to flow toward the side wall of the housing 100 through the vent 610. In the case where the spoiler 600 is not provided, the refrigerant flowing on the end face of the rotor 400 will continue to flow toward the axial direction of the rotor 400 to the air outlet 120. By adding the spoiler 600 to disturb the refrigerant, the refrigerant first flows toward the side of the housing 100 and then flows to the air outlet 120. By increasing the distance and duration of the refrigerant flowing to the air outlet 120, more oil can be separated from the refrigerant, and the amount of oil driven by the compressor by the refrigerant will be reduced, thereby improving the circulation efficiency of the oil and ensuring the stable operation of the machine. The oil plays a role of lubrication and cooling in the machine. By reducing the amount of oil discharged in the above manner, the friction of machine parts is avoided to increase, thereby avoiding damage to machine parts. In addition, by reducing the amount of oil discharged, the probability of the heat exchanger, evaporator and auxiliary pipelines being covered by the oil film can be reduced, avoiding affecting the heat exchange capacity of the machine.

[0074] In the present invention, the term "plurality" means two or more than two, unless otherwise clearly defined. The terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense.
