Description

Technical Field

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

[0002] As people's living standards improve, they have higher and higher requirements for environmental comfort, and air conditioners have become a necessity for almost every household. Rotary compressors are widely used in the field of household air conditioners due to their low production cost and low price. The vane is one of the core components of the compressor pump body, which directly affects the working efficiency and reliability of the compressor.

[0003] Due to the limitations of processing conditions, the vane groove structure of the cylinder cannot achieve the processing accuracy of surface grinding, so the shape and position tolerance and roughness of the vane groove are poor, which leads to large friction power consumption and leakage on the vane side, affecting the performance of the rotary compressor. During the operation of the rotary compressor, the vane slides back and forth in the vane groove of the cylinder. At the same time, the vane has relative motion friction with both sides of the vane groove of the cylinder, and when it moves in the compression chamber of the cylinder, it is offset by the pressure difference force of the gas on both sides, thereby increasing the friction power loss of the rotary compressor operation, increasing the power of the rotary compressor, but reducing the energy efficiency ratio. Moreover, the vane produces axial deformation along the vane groove, resulting in the decline of the vane's carrying capacity, tilting, fracture and other unfavorable phenomena. Therefore, the friction loss after the vane is deformed increases, the carrying capacity decreases, and the reliability of the rotary compressor is reduced. In the prior art, in order to reduce the wear of the vane, the method of increasing the gap and strengthening lubrication is often used to solve it, but this brings about problems such as poor sealing effect and large refrigerant leakage, which has a great impact on the performance of the compressor.

[0004] In view of this, there is an urgent need to improve the vane structure of the existing compressor to reduce the influence of the deformation of the vane on the performance of the compressor. Summary of the invention

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0040] In order to solve the technical problem that the vane 100 of the compressor in the prior art is deformed by heat during operation, resulting in increased friction loss and reduced bearing capacity of the vane 100 itself, refer to Figure 1-5 The present invention provides a vane 100, a compressor and an air conditioner, wherein the structural improvement of the vane 100 can reduce the influence of the deformation of the vane 100 on the performance of the compressor, and is applicable to compressors requiring the vane 100, especially rotary compressors, and also to various air conditioners containing compressors, such as vehicle air conditioners, household air conditioners and commercial air conditioners. The present invention is described in detail below through specific embodiments.

[0041] See also Figure 1-3 The present invention provides a slide 100, comprising a first slide body 10 and two second slide bodies 20. The first slide body 10 comprises a first side and a second side disposed opposite to each other, and the first side and the second side are both provided with a connector 11 and a first slot 12. Each second slide body 20 is respectively provided with a plug-in 21 and a second slot 22, and the second slot 22 and the plug-in 21 are disposed on a side of each second slide body 20 facing the first slide body 10, and each plug-in 21 is matched and connected with the corresponding connector 11, so that each second slide body 20 is respectively assembled on the first side and the second side, and the first slot 12 and the second slot 22 are communicated.

[0042] See also Figure 5 The following problems will interfere with the operation of the vane 100: First, the vane 100 slides in the vane slot 2002, and is deformed due to heat expansion during the sliding process. Since the vane 100 needs to keep in contact with the roller 2001 in the compression chamber 200 during operation, if the vane 100 is deformed along the sliding direction, the bearing capacity and reliability of the vane 100 will be reduced; second, since the vane 100 and the roller 2001 keep in contact during operation, as the roller 2001 rotates, the pressure on the vane 100 will be periodically offset. Under the load of the roller 2001, the reciprocating force change of the vane 100 will also cause the vane 100 to deform moderately. Therefore, the dual factors of thermal expansion and the pressure of the roller 2001 cause the vane 100 to deform.

[0043] The above technical solution provided by the embodiment of the present application is as follows: the structure of the slide 100 is set as a split structure, and the first slide body 10 and the second slide body 20 are connected by plugging. The first groove 12 provides a deformation space for the first slide body 10, and the second groove 22 provides a deformation space for the second slide body 20, allowing the slide 100 to expand due to heat and to deform under the pressure of the roller 2001, and the first groove 12 and the second groove 22 are connected, so that the overall deformation of the slide 100 is within a controllable range. The present invention has the following advantages:

[0044] Firstly, the deformation of the present invention mainly occurs inside the present invention, and the overall size expands and extends very little outward, thereby effectively reducing the friction loss between the sliding vane 100 and the sliding vane slot 2002 .

[0045] Secondly, since the deformation space is provided, the axial deformation of the vane 100 along the vane groove 2002 is avoided, thereby ensuring the load-bearing capacity of the vane 100 and avoiding adverse phenomena such as tilting and breakage; moreover, since the axial expansion of the vane 100 is effectively reduced, the design gap between the components in the compressor can be smaller, and there is no need to set an excessively large deformation space, thereby further ensuring the reliability of the compressor.

[0046] Thirdly, since there is no need to increase the gap of the vane groove 2002, the deformation of the vane 100 inwardly reduces wear and tear while also helping to form a thicker oil film to prevent leakage, thereby ensuring that the sealing performance of the compressor is not affected.

[0047] Moreover, after the assembly is completed, the first groove 12 and the second groove 22 are both enclosed inside the sliding vane 100, so that the sliding vane 100 has a complete outer surface, ensuring that the sliding vane 100 and the roller 2001 are in more stable contact, further improving the reliability of the compressor.

[0048] It can be understood that the plug-in 21 and the connector 11 are adapted to each other and are used to install and fix the first slider body 10 and the second slider body 20 together. In this embodiment, the plug-in 21 is a plug-in rod structure and the connector 11 is a socket structure. After the plug-in rod is inserted into the socket, they are connected by gluing, adding a sealing ring, etc. Of course, other methods can also be used to achieve a tight fit between the first slider body 10 and the second slider body 20.

[0049] In a preferred embodiment, the bottom wall and the side wall of each groove should be connected as smoothly as possible to prevent stress concentration between the bottom wall and the side wall, thereby greatly improving the elastic recovery of the slide 100, preventing alternating fracture at the intersection of the two, and improving the service life of the slide 100.

[0050] See also Figure 2 In a preferred embodiment, the first slide body 10 is provided with a third side, and the third side is provided with a groove 13 for cooperating with the driving member 2003, and the groove 13 separates the third side into two connecting parts 101. In this embodiment, the groove 13 is used to assemble with the driving member such as a hinge joint, so that the entire slide 100 slides in the slide groove 2002 under the action of the driving member 2003 and maintains contact with the roller 2001. The groove 13 separates the third side into two connecting parts 101, and the connecting part 101 is used to produce a pressing or positioning effect on the driving member. For example, when the driving member is a hinge joint, the groove 13 can not only ensure the rotation of the hinge joint, but also limit the position of the hinge joint.

[0051] See also Figure 2 and Figure 3 , further, in the above embodiment, the first groove 12 includes a blind groove 121 and a through groove 122. The blind groove 121 is respectively arranged on the first side and the second side in the forward direction and extends into the connecting portion 101; the through groove 122 passes through the first side and the second side. In this embodiment, in order to improve the structural deformation ability of the first vane body 10, the blind groove 121 and the through groove 122 are arranged at different positions, wherein the blind groove 121 is arranged in the connecting portion 101, which can effectively reduce the friction heat at the end of the first vane body 10 transferred to the middle area, and further can effectively reduce the axial expansion of the vane 100 along the vane groove 2002. Since the pump body assembly provides power for the roller 2001, the axial expansion of the vane 100 is reduced, which makes the design gap between the upper and lower flanges (or partitions) in the pump body assembly and the roller 2001 smaller, thereby facilitating the improvement of the sealing performance of the pump body and the energy efficiency of the compressor. The through slot 122 is disposed at a position far away from the groove 13 , so as to further increase the deformation space of the two side walls of the first slider body 10 , thereby improving its own flexibility.

[0052] Or further, in the above embodiment, the groove 13 includes a groove bottom 132 and two opposite groove walls 131. The two opposite groove walls 131 are respectively arranged on opposite sides of the connecting portion 101, and each groove wall 131 includes a first positioning groove 1311, a connecting surface 1312, and a second positioning groove 1313 connected in sequence. The two opposite first positioning grooves 1311 form a first matching area, the size of the first matching area is larger than the second matching area, and the two second positioning grooves 1313 form a second matching area. The groove bottom 132 is used to connect the two second positioning grooves 1313. The sizes of the first positioning groove 1311 and the second positioning groove 1313 are different, so that the first matching area and the second matching area are defined at different positions of the driving member. As mentioned above, the driving member is generally a hinged joint, then the first matching area and the second matching area should be spherical surfaces or conical surfaces with different radii, and the first positioning groove 1311 and the second positioning groove 1313 are correspondingly set to corresponding arc surfaces or conical surfaces. The connection surface 1312 is arranged so that there is a gap between the roller 2001 and the groove 13, thereby avoiding jamming in a high temperature operating environment.

[0053] See also Figure 3In a preferred embodiment, the second vane body 20 includes a bottom plate 201, a side arc plate 202 and three side flat plates 203, the bottom plate 201, the side arc plate 202 and the three side flat plates 203 enclose a second groove 22, and the side arc plate 202 is arranged on the side facing the compressor roller 2001 to form a point contact with the compressor roller 2001. The two second vane bodies 20 are connected to the first side and the second side of the second vane body 20. The second vane body 20 in this embodiment is a hollow polyhedron structure, the internal hollow space is the second groove 22, and the side arc plate 202 is arranged on the side abutting against the compressor roller 2001. The side arc plate 202 can ensure a large flexible deformation and also has a certain structural rigidity. Correspondingly, two side arc plates 202 are arranged on both sides of the entire slide 100, so that both ends of the slide 100 have a flexible structure, forming flexible protection for both ends of the slide 100, reducing the wear at both ends of the slide 100, and further reducing the axial expansion of the slide 100.

[0054] See also Figure 3 In a preferred embodiment, the first vane body 10 is provided with a fourth side, the fourth side faces the side of the compressor roller 2001, and the fourth side is provided with a convex arc surface 102 for contacting the compressor roller 2001. Since the contact position between the entire vane 100 and the roller 2001 is not fixed, it changes periodically with the rotation position of the roller 2001. Therefore, the first vane body 10 and the second vane body 20 will contact the roller 2001 in turn. The convex arc surface 102 is provided on the first vane body 10. In addition to ensuring close contact with the roller 2001, it can also cooperate with the second groove 22 inside to enhance the flexibility of the fourth side, thereby adjusting the axial expansion amount of the vane 100.

[0055] See also Figure 2 In a preferred embodiment, the distance between the first side and the second side is L1, the depth of the blind groove 121 is L2, 2≤L1 / L2≤5. The first slider body 10 is provided with a groove 13, and the blind groove 121 is divided into two sections to avoid the groove 13, which are respectively arranged on each connecting part 101, 2≤L1 / L2≤5. The distance between the connecting part 101 and the groove 13 is set within a certain range to avoid the groove 13 being too large to cause the positioning effect to fail to meet the expectations, and to avoid the groove 13 being too small to cause the positioning effect to fail to fully play.

[0056] In a preferred embodiment, the wall thickness of the side arc plate 202 and the side flat plate 203 is L3, 0.3mm≤L3≤3.5mm. Due to different compressor models and sizes, the size and size of the sliding vane 100 are also different. For the compressor models commonly used in household air conditioners, the wall thickness of the side arc plate 202 and the side flat plate 203 is set to 0.3mm≤L3≤3.5mm, which can make the deformation of the sliding vane 100 within a controllable range. Too large wall thickness will lead to excessive rigidity and affect deformation, and too small wall thickness will make the sliding vane 100 easily skew or break.

[0057] In a preferred embodiment, the height of the side arc plate 202 and the side flat plate 203 is H1, the depth of the second groove 22 is H2, and 1.1≤H1 / H2≤1.5. The size of the second slider body 20 not only needs to meet the assembly requirements, connect the plug-in 21 to the connector 11, but also enhance the flexibility of the second slider body 20, 1.1≤H1 / H2≤1.5 so that the second slider body 20 is a hollow structure, and the sufficient groove depth meets the deformation requirements of the slider 100.

[0058] See also Figure 4 In a preferred embodiment, the minimum wall thickness formed between the through slot 122 and the outer side surface of the first vane body 10 is L4, 0.3mm≤L4≤3.5mm. The through slot 122 runs through the first vane body 10, which is conducive to improving the flexibility of the two radial ends of the vane 100, thereby providing a deformation space for the deformation of the first vane body 10, and reducing the degree of wear between the vane 100 and the vane groove 2002. Considering the size of the first vane body 10, two or more through slots 122 are provided, so that the flexibility of each position of the first vane body 10 is basically the same, maintaining the stability of the center of gravity and the force balance of the overall structure.

[0059] In a preferred embodiment, the second groove 22 is a strip groove, and there are two plug-ins 21, which are spaced apart along the length direction of the second groove 22. In order to improve the stability of assembly, the number of plug-ins 21 is reasonably set according to the structure of the first slide body 10 and the second slide body 20, and two are set along the length direction of the second groove 22 to further improve the assembly accuracy. In this embodiment, the overall structure of the slide 100 is flat, the plug-in 21 is a plug-in rod structure, the plug-in direction is perpendicular to the second groove 22, and the connector 11 is set as a socket for easy assembly.

[0060] Furthermore, in the above embodiment, there is a gap between the two plugs 21 in the width direction of the strip groove. In order to improve the compactness of the structure, the plug 21 avoids the through groove 122 in the first groove 12, and the insertion hole and the through groove 122 are arranged in sequence along the thickness direction of the first slide body 10, so that the structure of the first slide body 10 is symmetrical, and thus remains stable when subjected to force.

[0061] Second, see Figure 5The present invention further provides a compressor, including a compression chamber 200, a roller 2001 rotatably disposed in the compression chamber 200, a vane groove 2002 disposed in the compression chamber 200, and a vane 100 of the above structure slidingly disposed in the vane groove 2002 and in contact with the roller 2001. The compressor of the present invention has all the technical effects of the above vane 100, which will not be described in detail here.

[0062] In a third aspect, the present invention further provides an air conditioner, comprising a compressor of the above structure.

[0063] The above technical solution provided by the embodiment of the present application is as follows: the structure of the slide 100 is set as a split structure, and the first slide body 10 and the second slide body 20 are connected by plugging. The first groove 12 provides a deformation space for the first slide body 10, and the second groove 22 provides a deformation space for the second slide body 20, allowing the slide 100 to expand due to heat and to deform under the pressure of the roller 2001, and the first groove 12 and the second groove 22 are connected, so that the overall deformation of the slide 100 is within a controllable range. The present invention has the following advantages:

[0064] First, the deformation of the present invention mainly occurs inside itself, and the overall size expands and extends outward very little, so it can effectively reduce the friction loss between the vane 100 and the vane slot 2002. Second, since the deformation space is provided, the axial deformation of the vane 100 along the vane slot 2002 is avoided, thereby ensuring the bearing capacity of the vane 100 and avoiding unfavorable phenomena such as tilting and breaking; and, since the axial expansion of the vane 100 is effectively reduced, the design gap between the components in the compressor can be smaller, and there is no need to set an excessively large deformation space, further ensuring the reliability of the compressor. Third, since there is no need to increase the gap of the vane slot 2002, the deformation of the vane 100 toward the inside of itself not only reduces wear, but also helps to form a thicker oil film to prevent leakage, which can ensure that the sealing performance of the compressor is not affected.

[0065] Moreover, after the assembly is completed, the first groove 12 and the second groove 22 are both enclosed inside the sliding vane 100, so that the sliding vane 100 has a complete outer surface, ensuring that the sliding vane 100 and the roller 2001 are in more stable contact, further improving the reliability of the compressor.
