Description

Technical Field

[0001] This application relates to the field of compressor technology, and in particular to a compressor and an air conditioner. Background Technology

[0002] With the continuous development of compressor technology, compressors are playing an increasingly important role in people's lives. To improve the volumetric efficiency of compressors, low-pressure chamber compressors typically employ two methods to reduce axial leakage of the scroll teeth: 1. Adding a sealing strip to the tooth tip; 2. Setting a back pressure chamber on the back of the stationary disc to press the tips and roots of the moving and stationary scroll teeth together with back pressure. For the second method, selecting a suitable sealing structure is crucial for sealing reliability and cost. Summary of the Invention

[0003] The purpose of this application is to provide a compressor and an air conditioner that solve the problem of poor sealing reliability of the compressor.

[0004] To achieve the above objectives, this application provides a compressor, including: a housing, a partition, a fixed scroll plate, a moving scroll plate, a float assembly, and a seal. The partition plate is disposed within the receiving cavity of the housing, and the partition plate divides the receiving cavity into a first receiving cavity and a second receiving cavity. The pressures in the first receiving cavity and the second receiving cavity are different. The float assembly and the seal are both located between the partition plate and the fixed scroll plate. The float assembly includes at least two floats, and the seal includes at least one of a first sealing portion and a second sealing portion. The first sealing portion is connected to the inner edge of the float located on the inner side of the at least two floats, and the second sealing portion is connected to the outer edge of the float located on the outer side of the at least two floats.

[0005] As an optional implementation, the compressor further includes a connector located between the fixed scroll plate and the float assembly, the connector having a groove, and the float assembly disposed within the groove.

[0006] As an optional implementation, the fixed vortex disk has a first groove, and the floating plate assembly is disposed in the first groove.

[0007] As an optional implementation, the seal includes a first sealing portion and a second sealing portion. The float located on the inner side of the at least two floats abuts against the first inner wall of the first groove through the first sealing portion, and the float located on the outer side of the at least two floats abuts against the second inner wall of the first groove through the second sealing portion. The first inner wall and the second inner wall are disposed opposite to each other.

[0008] As an optional implementation, the at least two floats include a first float, a second float, and a third float. The second float and the first sealing part are both embedded in the first through hole of the first float. The third float is located outside the first float and forms a second groove with the first float. The second sealing part is at least partially embedded in the second groove.

[0009] As an optional implementation, the first sealing part is obtained by heat treatment process.

[0010] As an optional implementation, the second float and the third float are integrally formed.

[0011] As an optional implementation, the at least two floats include a fourth float and a fifth float, wherein at least a portion of the fifth float and the first sealing portion are embedded in the second through hole of the fourth float, and at least a portion of the second sealing portion is embedded in the inner wall of the first groove.

[0012] As an optional implementation, the at least two floats include a sixth float and a seventh float, the seventh float being located outside the sixth float, and the sixth float and the seventh float forming a third groove, the second sealing part being at least partially embedded in the third groove, and the first sealing part being disposed on the fixed vortex disk.

[0016] In this embodiment, since the first sealing part is connected to the inner edge of the float plate located on the inner side of at least two float plates, and the second sealing part is connected to the outer edge of the float plate located on the outer side of at least two float plates, the first sealing part and the second sealing part enhance the sealing performance of the compressor, thereby ensuring good sealing performance of the compressor. At the same time, it makes the fixing effect of the first sealing part and the second sealing part better, reducing the occurrence of movement of the first sealing part and the second sealing part during the operation of the compressor, and enhancing the sealing reliability of the compressor.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] like Figure 1As shown, this application embodiment provides a compressor, including: a housing 10, a partition 20, a fixed scroll plate 30, a moving scroll plate 40, a float assembly 50, and a seal 60. The partition 20 is disposed within the receiving cavity of the housing 10, and the partition 20 divides the receiving cavity into a first receiving cavity 11 and a second receiving cavity 12. The pressures in the first receiving cavity 11 and the second receiving cavity 12 are different. The float assembly 50 and the seal 60 are both located between the partition 20 and the fixed scroll plate 30. The float assembly 50 includes at least two floats. The seal 60 includes at least one of a first sealing part 61 and a second sealing part 62. The first sealing part 61 is connected to the inner edge of the float located on the inner side of the at least two floats, and the second sealing part 62 is connected to the outer edge of the float located on the outer side of the at least two floats.

[0030] The working principle of the embodiments of this application can be found in the following description:

[0031] Because the compressor includes a seal 60, and the seal 60 includes at least one of a first sealing portion 61 and a second sealing portion 62, the sealing performance of the compressor is enhanced, thereby ensuring good sealing performance. At the same time, the first sealing portion 61 of the seal 60 is connected to the inner edge of the float plate located on the inner side of the at least two float plates included in the float plate assembly 50, and the second sealing portion 62 of the seal 60 is connected to the outer edge of the float plate located on the outer side of the at least two float plates included in the float plate assembly 50. This makes the fixing effect of the first sealing portion 61 and the second sealing portion 62 better, reducing the occurrence of movement of the first sealing portion 61 and the second sealing portion 62 during compressor operation, and enhancing the sealing reliability of the compressor.

[0032] The first accommodating cavity 11 can be referred to as the exhaust zone, and the second accommodating cavity 12 can be referred to as the intake zone. The pressure in the first accommodating cavity 11 can be greater than the pressure in the second accommodating cavity 12.

[0033] The partition 20 is used to separate the first accommodating cavity 11 and the second accommodating cavity 12. Optionally, the partition 20 can abut against the opposite side walls of the housing 10, thereby dividing the accommodating cavity into the first accommodating cavity 11 and the second accommodating cavity 12.

[0034] The volumes of the first accommodating cavity 11 and the second accommodating cavity 12 are not limited here. Optionally, the volume of the first accommodating cavity 11 may be smaller than the volume of the second accommodating cavity 12.

[0035] It should be noted that the number of floats included in the float assembly 50 is not limited here; the number of floats can be 2, 3, or 4, etc.

[0036] The inner edge of the float located on the inner side of the at least two floats can be understood as follows: the at least two floats are staggered, so there is a float located on the inner side of the at least two staggered floats. The inner edge of the float located on the inner side of the at least two floats can refer to the inner edge of the through hole or groove opened on the float. Alternatively, the float may be surrounded by other floats to form a through hole or groove, and the inner edge of the float may refer to the part of the float corresponding to the inner edge of the through hole or groove.

[0037] For example, the float that is relatively inside among at least two floats can be understood as follows: when there are two floats, and the two floats are staggered, after projecting the two floats onto each other, if most of the projected projection of one float is overlapped by the projected projection of the other float, and in the non-overlapping part, the projected projection of the other float is larger than the projected projection of the first float, then the first float can be said to be relatively inside, and the other float relatively outside.

[0038] For example, when there are three floats, and the three floats are staggered, after projecting the three floats onto the orthographic projection, the float corresponding to the orthographic projection between the orthographic projections of the other two floats is said to be relatively located on the inner side, while the other two floats can be said to be relatively located on the outer side.

[0039] The outer edge of the float that is located on the outer side of the at least two floats can be understood as: the at least two floats are staggered, so there is a float that is located on the outer side of the at least two staggered floats, and the outer edge of the float that is located on the outer side of the at least two floats can refer to: the outer edge of the float that is located on the outer side of the at least two staggered floats.

[0040] Similarly, the outer edge of the floatboard located on the outer side of the at least two floatboards can be referred to in the example of the floatboard located on the inner side of the at least two floatboards mentioned above, and will not be repeated here.

[0041] It should be noted that, as an optional implementation, the compressor may also include a connector located between the fixed scroll plate 30 and the float assembly 50. The connector has a groove, and the float assembly 50 is disposed within the groove. This placement of the float assembly 50 within the groove enhances its positioning effect.

[0042] As an optional implementation, see [link to implementation details]. Figure 1The fixed vortex disk 30 and the floating plate assembly 50 enclose a back pressure chamber 70, and the fixed vortex disk 30 and the moving vortex disk 40 enclose a plurality of compression chambers 71. The back pressure chamber 70 communicates with at least a portion of the plurality of compression chambers 71. The first sealing part 61 separates the back pressure chamber 70 and the first accommodating cavity 11, and the second sealing part 62 separates the back pressure chamber 70 and the second accommodating cavity 12.

[0043] The back pressure chamber 70 can be connected to one of the multiple compression chambers 71, and the multiple compression chambers 71 can be arranged sequentially at intervals.

[0044] In this embodiment, since the fixed vortex disk 30 and the floating plate assembly 50 enclose a back pressure chamber 70, and the first sealing part 61 separates the back pressure chamber 70 and the first accommodating cavity 11, and the second sealing part 62 separates the back pressure chamber 70 and the second accommodating cavity 12, the sealing performance of the back pressure chamber 70 is enhanced, and the sealing problem of the back pressure chamber 70 is solved.

[0045] As an optional implementation, see [link to implementation details]. Figure 1 The fixed vortex disk 30 has a first groove 31, and the floating plate assembly 50 is disposed in the first groove 31.

[0046] In this embodiment, the float assembly 50 is disposed within the first groove 31, thereby enhancing the limiting effect on the float assembly 50.

[0047] As an optional implementation, the seal 60 includes a first sealing portion 61 and a second sealing portion 62. The float located on the inner side of the at least two floats abuts against the first inner wall of the first groove 31 through the first sealing portion 61, and the float located on the outer side of the at least two floats abuts against the second inner wall of the first groove 31 through the second sealing portion 62. The first inner wall and the second inner wall are disposed opposite to each other.

[0048] The first sealing part 61 and the second sealing part 62 can be two separate sealing elements 60, or the first sealing part 61 and the second sealing part 62 can be two parts of a single sealing element 60, that is, the first sealing part 61 and the second sealing part 62 can be an integrally formed structure.

[0049] Optionally, the first sealing part 61 can be referred to as the inner sealing part, and the second sealing part 62 can be referred to as the outer sealing part.

[0050] In this embodiment of the application, by simultaneously providing the first sealing part 61 and the second sealing part 62, the sealing effect can be further improved.

[0051] As another alternative implementation, see Figure 2 and Figure 3 The at least two floats include a first float 51, a second float 52, and a third float 53. The second float 52 and the first sealing part 61 are both embedded in the first through hole 511 of the first float 51. The third float 53 is located outside the first float 51, and the third float 53 and the first float 51 form a second groove. The second sealing part 62 is at least partially embedded in the second groove.

[0052] The first float plate 51 and the second float plate 52 can cooperate with each other to fix the first sealing part 61, while the third float plate 53 and the first float plate 51 can cooperate with each other to fix the second sealing part 62.

[0053] It should be noted that the materials of the first sealing part 61 and the second sealing part 62 may be the same or different.

[0054] The connection method between the first float plate 51 and the second float plate 52, and the connection method between the first float plate 51 and the third float plate 53 are not specifically limited here.

[0055] Optionally, the first float plate 51 and the second float plate 52 can be connected by interference fit, welding or thread, and the first float plate 51 and the third float plate 53 can also be connected by interference fit, welding or thread.

[0056] In this embodiment, at least two floats include a first float 51, a second float 52, and a third float 53. The second float 52 and the first sealing part 61 are both embedded in the first through hole 511 of the first float 51. The third float 53 is located outside the first float 51, and the third float 53 and the first float 51 form a second groove. This makes the float assembly 50 easy to maintain and install, with low installation cost and high installation efficiency, and also makes the float assembly 50 more reliable.

[0057] As an optional implementation, the first sealing part 61 is obtained by heat treatment process.

[0058] In this embodiment, only the first sealing part 61 is processed by heat treatment. Compared with the method that all sealing parts 60 need to be heat-processed, the processing cost in this embodiment is lower and the processing efficiency is higher.

[0059] As an optional implementation, see [link to implementation details]. Figure 4 , Figure 5 and Figure 6 The second float 52 and the third float 53 are integrally formed structures.

[0060] In this embodiment, the second float plate 52 and the third float plate 53 are integrally formed, which enhances the connection strength between the second float plate 52 and the third float plate 53.

[0061] As an optional implementation, see [link to implementation details]. Figure 7 , Figure 8 and Figure 9 The at least two floats include a fourth float 54 and a fifth float 55. The fifth float 55 and the first sealing part 61 are both embedded in the second through hole 541 of the fourth float 54. The second sealing part 62 is at least partially embedded in the inner wall of the first groove 31.

[0062] Optionally, a receiving groove may be provided on the inner wall of the first groove 31, and at least a portion of the second sealing part 62 may be embedded in the receiving groove.

[0063] In this embodiment, the first sealing part 61 is embedded in the second through hole 541 of the fourth float plate 54, while the second sealing part 62 is at least partially embedded in the inner wall of the first groove 31. This enhances the diversity and flexibility of the placement of the second sealing part 62 and improves the fixing performance of the second sealing part 62.

[0064] As an optional implementation, see [link to implementation details]. Figure 10 and Figure 11 The at least two floats include a sixth float 56 and a seventh float 57. The seventh float 57 is located outside the sixth float 56, and the sixth float 56 and the seventh float 57 form a third groove. The second sealing part 62 is at least partially embedded in the third groove, and the first sealing part 61 is disposed on the fixed vortex disk 30.

[0065] The specific location of the first sealing part 61 on the fixed scroll plate 30 is not limited here. Optionally, a connecting protrusion may be provided on the fixed scroll plate 30, and the connecting protrusion passes through the float assembly 50, and there is a gap between the connecting protrusion and the partition plate 20. The first sealing part 61 may be provided on the connecting protrusion.

[0066] Optionally, the compressor may also include an intermediate component 80, which may be located in the gap between the partition 20 and the float assembly 50.

[0067] It should be noted that, based on this embodiment, the intermediate component 80 can also be disposed between the connecting protrusion and the partition plate 20, and there can be a gap between the connecting protrusion and the intermediate component 80. Part of the structure of the intermediate component 80 can pass through the first air hole 21 on the partition plate 20, and a second air hole 81 can be opened in the intermediate component 80. A third air hole 32 can be opened on the fixed vortex disk 30. The first accommodating cavity 11 can communicate with at least a part of the compression chamber 71 through the first air hole 21, the second air hole 81, and the third air hole 32. Optionally, a filter element can be provided at the connection between the second air hole 81 and the third air hole 32 to enhance the filtration effect.

[0068] In this embodiment, the second sealing part 62 is at least partially embedded in the third groove, and the first sealing part 61 is disposed on the fixed scroll plate 30. This enhances the diversity and flexibility of the placement of the first sealing part 61 and improves the fixing performance of the first sealing part 61.

[0069] As an optional implementation, see [link to implementation details]. Figure 2 The first float 51 is provided with a weight reduction groove 512.

[0070] The specific structure of the weight reduction groove 512 is not limited here. Optionally, the cross-section of the weight reduction groove 512 can be rectangular, or the cross-section of the weight reduction groove 512 can be elliptical, etc.

[0071] In this embodiment of the application, by opening a weight-reducing groove 512 on the first float 51, the weight of the first float 51 can be reduced, thereby reducing the weight of the entire compressor.

[0072] It should be noted that, optionally, at least one of the second float plate 52, the third float plate 53, the fourth float plate 54, the fifth float plate 55, the sixth float plate 56 and the seventh float plate 57 may also have a weight reduction groove, which is not limited here.
