Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular, to a scroll compressor and an air conditioner. Background Art

[0002] In a scroll compressor, the moving disk and the stationary disk rotate and engage to compress the refrigerant from a low-pressure gas into a high-pressure gas. During the compression process, the moving disk moves away from the stationary disk, causing an increase in the axial clearance between the scroll teeth of the moving disk and the stationary disk, which easily leads to problems such as gas leakage and increased power consumption of the compressor. There are currently two relatively common solutions. One is to install a sealing strip on the top surface of the scroll teeth of the moving disk and the stationary disk to prevent internal leakage caused by an increase in the axial clearance. The other is to form a back pressure chamber between the back surface of the moving disk and the bracket, introduce intermediate-pressure refrigerant, and push the moving disk closer to the stationary disk to reduce the axial clearance and reduce gas internal leakage. However, the above solutions have the following disadvantages. First, installing a sealing strip on the scroll teeth requires machining a groove on the scroll teeth. Due to structural size limitations, machining is difficult, and the thin-wall structure is easily damaged, resulting in seal failure and reduced reliability. Second, there are relative rotating components in the components constituting the back pressure chamber. The moving disk rotates and translates relative to the bracket (or wear-resistant plate), and the crankshaft rotates relative to the bracket, making it difficult to seal the back pressure chamber. In the prior art, sealing of the back pressure chamber is also achieved by setting a seal on the mating surface between the moving disk and the bracket (or wear-resistant plate). However, due to the structural size limitations of the moving disk, the mating surface size between the moving disk and the wear-resistant plate is small, resulting in difficulty in machining the sealing groove, and the thin-wall structure of the groove reduces the reliability of the compressor. When friction occurs between the moving disk and the wear-resistant plate, causing part wear, the difficulty of sealing the back pressure chamber is further increased, and the sealing difficulty between the crankshaft and the bracket needs to be considered. The overall reliability of the back pressure chamber has not been improved.

[0003] Especially in the field of pure electric vehicles, the requirements for the compressor are that the volume is smaller and the weight is lighter, and it also needs to have higher performance. Therefore, a scroll compressor made of aluminum alloy material is usually used. However, due to the size limitations of the compressor and the poor wear resistance of aluminum alloy, in the face of problems such as compression chamber leakage and part wear, the defects of the prior art are more obvious, and the problem of anti-leakage cannot be well solved by the technical means in the prior art. Summary of the Invention

[0004] The main object of the present invention is to provide a scroll compressor and an air conditioner to solve the problem that the wear of the wear-resistant plate cannot be automatically compensated in the prior art.

[0005] To achieve the above object, according to one aspect of the present invention, a scroll compressor is provided, including: a stationary disk; a moving disk, the moving disk is meshed with the stationary disk to perform compression operation; a bracket, the moving disk is rotatably and translationally arranged relative to the bracket, and the bracket is provided with a receiving portion; a wear-resistant portion, the wear-resistant portion is located between the bracket and the moving disk; an elastic portion, at least part of the elastic portion is located in the receiving portion, and the elastic portion is used to apply an elastic force to the wear-resistant portion so that when the wear-resistant portion wears, the wear-resistant portion realizes automatic wear compensation.

[0006] Further, when the moving disk and the stationary disk perform compression operation, the elastic force applied by the elastic portion to the wear-resistant portion cancels out the axial force acting on the moving disk in the direction away from the stationary disk.

[0007] Further, the wear-resistant portion includes: an annular body, a first annular protrusion is formed on the surface of the annular body facing the moving disk, and the first annular protrusion cooperates with the moving disk to enclose a sealed space.

[0010] Further, a rotation and translation region is formed between the inner circle and the outer circle of the first annular protrusion, and the end of the second annular protrusion performs rotation and translation in the rotation and translation region.

[0011] Further, an oil return channel is provided at the outer edge of the annular body, and the oil return channel is located outside the first annular protrusion.

[0017] According to another aspect of the present invention, there is provided an air conditioner including a scroll compressor, and the scroll compressor is the above-mentioned scroll compressor.

[0018] By applying the technical solution of the present invention, an elastic portion is provided between the bracket and the wear-resistant portion for the moving disk and the static disk. When the wear-resistant portion generates a certain thickness of wear after long-term friction, the elastic portion jacks up the wear-resistant portion toward the moving disk side, causing the wear-resistant portion to move toward the moving disk side to compensate for the worn thickness of the wear-resistant portion, so that the wear-resistant portion realizes the function of automatic wear compensation, effectively improving the sealing reliability between the moving disk, the static disk and the bracket. By adding an elastic portion to the bracket and the wear-resistant portion, an elastic force is provided to push the moving disk toward the static disk. When the moving disk and the static disk compress the refrigerant, the axial force of the moving disk away from the static disk can be offset, and the back pressure effect can be achieved without additionally providing a back pressure chamber structure, eliminating the problem that the performance of the compressor decreases due to the failure of the back pressure chamber seal.

[0041] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present application is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and thus their description will be omitted.

[0042] Combined with Figures 1 to 7 As shown, according to an embodiment of the present invention, a scroll compressor is provided.

[0043] Specifically, as Figure 1 shown, the scroll compressor includes a stationary disk 3, a moving disk 4, a bracket 7, a wear-resistant part 5, and an elastic part 6. The moving disk 4 is meshed with the stationary disk 3 to perform a compression operation. The moving disk 4 is rotatably and translationally arranged relative to the bracket 7, and the bracket 7 is provided with a receiving part 71. The wear-resistant part 5 is located between the bracket 7 and the moving disk 4. At least a part of the elastic part 6 is located in the receiving part 71, and the elastic part 6 is used to apply an elastic force to the wear-resistant part 5 so that when the wear-resistant part 5 is worn, the wear-resistant part 5 realizes automatic wear compensation.

[0044] In this embodiment, by providing the elastic part 6 between the bracket 7 and the wear-resistant part 5, when the wear-resistant part 5 generates a certain thickness of wear after long-term friction, the elastic part 6 pushes the wear-resistant part toward the moving disk 4, so that the wear-resistant part 5 moves toward the moving disk 4 to compensate for the worn thickness of the wear-resistant part 5, thereby enabling the wear-resistant part 5 to realize the function of automatic wear compensation and effectively improving the sealing reliability between the moving disk 4 and the bracket. By adding the elastic part to the bracket 7 and the wear-resistant part 5, an elastic force is provided to push the moving disk 4 toward the stationary disk 3. When the moving disk 4 and the stationary disk 3 compress the refrigerant, the axial force of the moving disk 4 away from the stationary disk 3 can be offset, and the back pressure effect can be achieved without additionally providing a back pressure chamber structure, eliminating the problem of the compressor performance degradation caused by the failure of the back pressure chamber seal.

[0045] Wherein, when the moving disk 4 and the stationary disk 3 perform a compression operation, the elastic force applied by the elastic part 6 to the wear-resistant part 5 cancels out the axial force of the moving disk 4 in the direction away from the stationary disk 3. For example, when the moving disk 4 and the stationary disk 3 compress the refrigerant, the axial force of the moving disk 4 away from the stationary disk 3 can be offset, thereby effectively reducing the axial clearance between the scroll teeth of the moving disk 4 and the stationary disk 3, avoiding the problem of internal gas leakage of the compressor, and improving the sealing reliability between the moving disk 4 and the stationary disk 3 of the compressor.

[0046] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown in the figure, the wear-resistant part 5 includes an annular body. A first annular protrusion 51 is formed on the surface of the annular body facing the driving disk 4. The first annular protrusion 51 cooperates with the driving disk 4 to enclose a sealed space. Correspondingly, a second annular protrusion 41 is provided on the side of the driving disk 4 facing the wear-resistant part 5. The end face of the second annular protrusion 41 is in contact with the end face of the first annular protrusion 51. Such a setting enables the driving disk 4 to always be in contact with the wear-resistant part 5 during the operation of the compressor, which can improve the sealing reliability between the wear-resistant part 5 and the driving disk 4.

[0047] As Figure 3 , Figure 4 and Figure 5 shown in the figure, the second annular protrusion 41 is arranged along the outer edge of the driving disk 4, and the width of the second annular protrusion 41 in the radial direction of the driving disk 4 is smaller than the width of the first annular protrusion 51 in the radial direction of the driving disk 4. During the sliding process of the driving disk 4 during compression operation, the second annular protrusion 41 on the driving disk 4 and the first annular protrusion 51 on the wear-resistant part 5 have good contact in the radial direction of the driving disk 4, which improves the reliability of the compressor.

[0048] As Figure 3 , Figure 4 and Figure 5 shown in the figure, a rotation and translation region is formed between the inner circle and the outer circle of the first annular protrusion 51, and the end of the second annular protrusion 41 performs rotation and translation within the rotation and translation region. Ensure that the end of the second annular protrusion 41 performs rotation and translation within the rotation and translation region formed by the first annular protrusion 51. Make the second annular protrusion 41 and the first annular protrusion 51 on the wear-resistant part 5 have good contact in the radial direction of the driving disk 4, which improves the reliability of the compressor.

[0049] As Figure 1 , Figure 4 and Figure 5 shown in the figure, an oil return channel 52 is provided at the outer edge of the annular body in the wear-resistant part 5. The oil return channel 52 is located outside the first annular protrusion 51. When the compressor is working, the separated lubricating oil 11 enters the oil return channel 52 on the annular body in the wear-resistant part 5 through the oil return hole (not marked) on the static disk 3 and then enters the oil return groove 72 on the bracket 7. The lubricating oil 11 lubricates the bearing in the bracket 7 and is discharged into the low-pressure cavity 9 of the compressor.

[0050] As Figure 6As shown, the receiving portion 71 on the bracket 7 includes a receiving groove. The receiving groove is formed on the end face of the bracket 7 facing the moving disk 4. There are a plurality of receiving grooves, and the plurality of receiving grooves are arranged at intervals along the circumferential direction of the bracket 7. An elastic portion 6 is provided in each receiving groove. By placing the elastic portion 6 in the receiving groove, the refrigerant can be compressed under different working conditions. According to the different axial forces between the moving disk 4 and the static disk 3, the properties such as the material, quantity, and setting height of the elastic portion 6 placed can be selected to offset axial forces of different magnitudes. In this embodiment, the receiving grooves are arranged at intervals along the circumferential direction of the bracket 7, so that each part of the wear-resistant portion 5 along the circumferential direction can receive the elastic force of the elastic portion, ensuring that the wear-resistant portion 5 is uniformly stressed in the circumferential direction and will not shift, thereby enhancing the reliability of the circumferential seal between the moving disk 4 and the static disk 3.

[0051] An assembly hole for installing a crankshaft is formed in the middle of the bracket 7, and the receiving portion 71 includes an annular groove. The annular groove is formed on the end face of the bracket 7 facing the moving disk 4, and the annular groove is arranged concentrically with the assembly hole. Among them, there are a plurality of elastic portions 6, and the plurality of elastic portions 6 are arranged at intervals in the annular groove. Such a setting can also ensure that the wear-resistant portion 5 is uniformly stressed in the circumferential direction and will not shift. At the same time, it enables the wear-resistant portion to achieve the function of automatically compensating for friction loss.

[0052] As Figure 6 shown, an oil return groove 72 is formed on the bracket 7. The oil return groove 72 extends along the radial direction of the bracket 7 and is used to receive the lubricating oil 11 that enters the oil return channel on the annular body of the wear-resistant portion 5 through the oil return hole on the static disk 3.

[0053] As Figure 2 shown, the elastic portion 6 is a spring, pressure-resistant rubber, or elastic corrugated pipe. When the elastic portion 6 is installed in the receiving groove, it is ensured that the elastic portion 6 has an elastic force towards the wear-resistant portion 5. In this way, after long-term use, even if the wear-resistant portion 5 realizes automatic wear compensation, the elastic portion 6 is always in an effective state, that is, the force exerted by the elastic portion 6 towards the wear-resistant portion 5 will not disappear.

[0054] As Figure 7As shown, the scroll compressor further includes a guide member 8. At least a part of the guide member 8 is located within the accommodating portion 71. The first end of the elastic portion 6 is disposed along the outer peripheral side of the guide member 8. The second end of the elastic portion 6 abuts against the bracket 7. The elastic portion 6 applies an elastic force to the wear-resistant portion 5 through the guide member 8. By arranging the guide member 8 between the elastic portion 6 and the wear-resistant portion 5, the elastic portion 6 applies an elastic force to the wear-resistant portion 5 more reliably, thereby enhancing the sealing reliability between the moving disk 4 and the stationary disk 3. To limit the axial clearance amount when the moving disk 4 and the stationary disk 3 are engaged, the accommodating portion 71 can be configured as an annular groove having a stepped surface, and the guide member 8 and the elastic portion 6 are placed inside. The clearance between the guide member 8 and the stepped surface is defined, that is, this clearance ensures the maximum axial clearance between the moving disk 4 and the stationary disk 3, thereby ensuring the reliable operation of the compressor. Among them, the guide member 8 can be a columnar structure having a flange at one end, the elastic portion 6 is a spring, the wear-resistant portion 5 is a wear-resistant gasket, the end of the guide member 8 having the flange abuts against the wear-resistant gasket, the other end of the guide member 8 is inserted into the inner ring of the spring, and the spring abuts against the surface of the flange. Such an arrangement can ensure that the spring will not be offset when compressed, that is, such an arrangement can ensure that the elastic force applied by the spring toward the wear-resistant gasket is always along the axial direction of the moving disk 4.

[0055] Among them, the guide member 8 and the wear-resistant gasket can be arranged as an integral structure, which can further improve the reliability of the compressor.

[0056] In another embodiment of the present application, the scroll compressor is composed of a housing 13, a stator and a rotor (not shown), a crankshaft 14, a bracket 7, etc. Among them, a low-pressure chamber 9 is formed on the side of the bracket 7 away from the moving disk 4, the cavity in the middle of the meshing of the scroll teeth of the moving disk 4 and the stationary disk 3 is the compression chamber 10, and the high-pressure chamber 12 is formed by the back side of the stationary disk 3 and the front cover 1. The low-pressure gaseous refrigerant enters the low-pressure chamber 9 from the suction port 131, is compressed into medium-pressure gas by the moving disk 4 and the stationary disk 3, and then is discharged to the high-pressure chamber 12 through the exhaust hole of the stationary disk 3. When the moving disk 4 and the stationary disk 3 compress the refrigerant, the internal pressure gradually increases, generating a gas axial force, causing the moving disk 4 to move in a direction away from the stationary disk 3.

[0057] In the present application, to prevent the moving disk 4 from moving away from the stationary disk 3, an elastic portion 6 is provided at the positions of the bracket 7 and the wear-resistant portion 5. The elastic portion 6 is composed of a spring, pressure-resistant rubber or an elastic bellows. The moving disk 4 performs a rotational translation, and the second annular protrusion 41 on the back surface of the moving disk 4 contacts the wear-resistant portion 5. The operating area of the second annular protrusion 41 is the annular area of the end surface of the first annular protrusion 51. The elastic portion 6 is placed in the annular groove of the bracket 7 to apply an elastic force to support the first annular protrusion 51 on the wear-resistant portion 5. Ensure the axial clearance between the moving disk 4 and the stationary disk 3. At the same time, when the moving disk 4 and the wear-resistant portion 5 are worn after long-term friction, the wear-resistant portion 5 supported by the elastic portion 6 can be used to compensate for the wear amount.

[0058] The accommodating parts 71 on the bracket 7 can be provided in multiple numbers and are evenly arranged on the end face of the bracket 7. Optionally, the accommodating part 71 on the bracket 7 can also be provided as an annular groove, and the elastic part 6 is placed in the annular groove. By adopting the technical solution of the present application, there is no need to provide sealing parts such as shaft seals between the bracket 7 and the crankshaft 14, and there is no problem of leakage in the back pressure chamber. The compressor adopting this structure is simple and easy to process, effectively reducing the production cost of the compressor. An oil return channel 52 is arranged on the wear-resistant part 5, and an oil return groove 72 is arranged on the bracket 7. The oil return channel 52 on the wear-resistant part 5 is communicated with the oil return hole (not marked) of the static disk 3, and the oil return channel 52 on the wear-resistant part 5 is communicated with the oil return groove 72 on the bracket 7. After the gas in the high-pressure chamber 12 is separated by the oil and gas in the oil separation pipe 2, the gaseous refrigerant is discharged, and the separated lubricating oil 11 enters the oil return channel 52 on the wear-resistant part 5 through the oil return hole (not marked) of the static disk 3 and then enters the oil return groove 72 on the bracket 7. The lubricating oil 11 lubricates the bearing and is discharged into the low-pressure chamber 9.

[0059] The scroll compressor in the above embodiment can also be used in the technical field of air-conditioning equipment. That is, according to another aspect of the present invention, an air conditioner is provided. The air conditioner includes a scroll compressor, and the scroll compressor is the scroll compressor in the above embodiment.
