Description

Technical Field

[0001] This application relates to the field of scroll compressor technology, and in particular to an exhaust pipe assembly for a scroll compressor and a scroll compressor. Background Technology

[0002] Due to its inherent structural characteristics, the crankshaft of a scroll compressor agitates the airflow inside the compressor during rotation, causing the gas to mix with the refrigeration oil. This results in a higher oil content in the discharged gas. Increased oil discharge from a scroll compressor leads to a decrease in its performance.

[0003] The exhaust pipe of existing scroll compressors is only used as a pipeline for gas flow and cannot separate the refrigeration oil in the gas mixture. Utility Model Content

[0004] In view of this, the purpose of this application is to provide an exhaust pipe assembly for a scroll compressor and a scroll compressor, so as to solve the problem of high content of refrigeration oil in the gas discharged from the scroll compressor.

[0005] According to a first aspect of the present invention, an exhaust pipe assembly for a scroll compressor is provided, wherein the exhaust pipe assembly for the scroll compressor includes: an exhaust pipe connector seat, a first end of the exhaust pipe connector seat being connected to the scroll compressor, and a first channel being formed in the exhaust pipe connector seat; a helical blade disposed in the first channel; and an exhaust pipe connector installed at a second end of the exhaust pipe connector seat, and a second channel being formed in the exhaust pipe connector seat, the second channel being connected to the first channel.

[0006] Preferably, the exhaust pipe assembly for the scroll compressor further includes a filter screen disposed between the first channel and the second channel.

[0007] Preferably, the inner wall of the second end of the exhaust pipe connector seat is provided with an annular groove, the annular groove is connected to the port of the second end of the exhaust pipe connector seat, the end of the exhaust pipe connector is inserted into the annular groove, the filter screen includes a mesh part and an outer ring part, the mesh part is disposed in the outer ring part, and the outer ring part is sandwiched between the end of the exhaust pipe connector and the axial end of the annular groove.

[0008] Preferably, a threaded groove is formed on the inner wall of the exhaust pipe connector seat, and the outer periphery of the helical blade is engaged in the threaded groove.

[0009] Preferably, the spiral blade has a rod extending axially at its center.

[0010] Preferably, an annular mounting groove is formed on the outer wall of the first end of the exhaust pipe connector seat, and an exhaust hole is provided on the outer wall of the scroll compressor. The portion of the exhaust pipe connector seat with the mounting groove is inserted into the exhaust hole.

[0011] Preferably, the exhaust pipe connector seat is installed laterally on the scroll compressor, and the bottom of the inner wall of the exhaust pipe connector seat is provided with an axially extending oil groove, which communicates with the interior of the scroll compressor.

[0012] Preferably, the exhaust pipe connector has a bend in the middle, the end of the exhaust pipe connector connected to the exhaust pipe connector seat is arranged laterally, and the other end of the exhaust pipe connector extends vertically upward.

[0013] Preferably, the exhaust pipe connector seat is installed vertically on the scroll compressor, and the exhaust pipe connector extends vertically.

[0014] According to a second aspect of the present invention, a scroll compressor is provided, wherein the scroll compressor includes an exhaust pipe assembly for a scroll compressor as described above.

[0015] The present invention relates to an exhaust pipe assembly for a scroll compressor and a scroll compressor, wherein the first end of the exhaust pipe connector is connected to the scroll compressor. A first channel is formed within the exhaust pipe connector, and a helical blade is disposed within the first channel. An exhaust pipe connector is installed at the second end of the exhaust pipe connector, and a second channel is formed within the exhaust pipe connector, which is connected to the first channel. This arrangement ensures that the gas in the scroll compressor passes through the helical blades during discharge. Due to the high density of the refrigerant oil droplets mixed in the gas, after being guided by the helical blades, the refrigerant oil droplets in the gas separate from the gas under the action of centrifugal force, thereby reducing the oil discharge rate of the scroll compressor. This effectively solves the problem of high refrigerant oil content in the gas discharged from the scroll compressor.

[0031] like Figures 1 to 3As shown, according to a first aspect of the present invention, an exhaust pipe assembly for a scroll compressor is provided, the exhaust pipe assembly for the scroll compressor including an exhaust pipe connector seat 1, a spiral blade 2 and an exhaust pipe connector 3.

[0032] In the following description, reference will be made to Figures 1 to 3 The specific structure of the exhaust pipe assembly used in the scroll compressor and the connection relationship of the above-mentioned components are described in detail.

[0033] like Figures 1 to 3 As shown, in this embodiment, the exhaust pipe connector 1 can be a tubular structure. The first end of the exhaust pipe connector 1 can be connected to the scroll compressor. A first channel 10 is formed within the exhaust pipe connector 1, and the helical blade 2 can be disposed within the first channel 10. The exhaust pipe connector 3 can be installed at the second end of the exhaust pipe connector 1. A second channel 30 can be formed within the exhaust pipe connector 3, and the second channel 30 is connected to the first channel 10. This arrangement ensures that the gas in the scroll compressor passes through the helical blade 2 during discharge. Due to the high density of the refrigerant oil droplets mixed in the gas, after being guided by the helical blade 2, the refrigerant oil droplets in the gas will separate from the gas under centrifugal force, thereby reducing the oil discharge rate of the scroll compressor.

[0034] Preferred, such as Figures 1 to 3 As shown, in this embodiment, the exhaust pipe assembly for the scroll compressor may further include a filter screen 4. The filter screen 4 may be disposed between the first channel 10 and the second channel 30, so that after the gas passes through the guide of the spiral blades 2, it needs to be further filtered by the filter screen 4 before being discharged, thereby greatly reducing the content of residual refrigeration oil in the gas.

[0035] Furthermore, preferably, such as Figures 1 to 3 As shown, in this embodiment, an annular groove may be formed on the inner wall of the second end of the exhaust pipe connector seat 1. The annular groove may be connected to the port of the second end of the exhaust pipe connector seat 1, such that the diameter of the hole in the exhaust pipe connector seat 1 with the annular groove is larger than the diameter of the hole in other positions. The end of the exhaust pipe connector 3 may be inserted axially into the annular groove (i.e., inserted into the second end of the exhaust pipe connector seat 1).

[0036] Further optimized, such as Figures 1 to 3As shown, in this embodiment, the filter screen 4 may include a mesh portion 40 and an outer ring portion 41. The mesh portion 40 is used for filtration and is disposed within the outer ring portion 41. When the filter screen 4 is installed in the exhaust pipe connector seat 1, the outer ring portion 41 can be clamped between the end of the exhaust pipe connector 3 and the axial end of the annular groove (i.e., the radially protruding inner wall of the exhaust pipe connector seat 1), thereby fixing the position of the filter screen 4. After installation, the exhaust pipe connector seat 1, the filter screen 4, and the exhaust pipe connector 3 can be fixed by brazing to prevent movement during use.

[0037] Preferred, such as Figures 1 to 3 As shown, in this embodiment, a threaded groove 11 can be formed on the inner wall of the exhaust pipe connector seat 1. The outer periphery of the helical blade 2 can be engaged in the threaded groove 11, thereby fixing the helical blade 2 in the exhaust pipe connector seat 1. Further, preferably, a rod portion 20 extending axially can be provided in the center of the helical blade 2, and the rod portion 20 can be integrally formed with the helical blade 2. The operator can screw the helical blade 2 into the exhaust pipe connector seat 1 by screwing the rod portion 20 to complete the installation.

[0038] In addition, preferred, such as Figures 1 to 3 As shown, in this embodiment, an annular mounting groove 13 may be formed on the outer wall of the first end of the exhaust pipe connector 1. A circular exhaust hole is formed on the outer wall of the scroll compressor. The portion of the exhaust pipe connector 1 with the mounting groove 13 can be inserted into the exhaust hole, thereby connecting the exhaust pipe connector 1 to the interior of the scroll compressor. The exhaust pipe connector 1 can be welded to the outer wall of the scroll compressor, thereby tightly installing the exhaust pipe connector 1 onto the scroll compressor.

[0039] Preferably, in such Figure 1 and Figure 2 In the illustrated embodiment, the exhaust pipe connector 1 can be installed laterally (i.e., radially) on the scroll compressor. In this case, the exhaust pipe connector 1 can be installed on the casing 5 of the scroll compressor. An axially extending oil groove 12 can be formed at the bottom of the inner wall of the exhaust pipe connector 1. The oil groove 12 can communicate with the interior of the scroll compressor. After being guided by the spiral blades 2, the refrigeration oil droplets in the gas are separated and suspended on the inner wall of the exhaust pipe connector 1, and finally converge into the oil groove 12 under the action of gravity, and then flow back to the scroll compressor through the oil groove 12.

[0040] Furthermore, preferably, such as Figure 1 and Figure 2As shown, when the exhaust pipe connector 1 is installed laterally on the scroll compressor, a bend 31 can be provided in the middle of the exhaust pipe connector 3. This allows the end of the exhaust pipe connector 3 connected to the exhaust pipe connector 1 to be arranged laterally, while the other end of the exhaust pipe connector 3 extends vertically upward, so as to prevent the oil collected in the oil sump 12 from being discharged from the exhaust pipe connector 3.

[0041] Preferably, in such Figure 3 In the illustrated embodiment, the exhaust pipe connector 1 can be installed vertically (i.e., along the axial direction of the scroll compressor) on the scroll compressor. In this case, the exhaust pipe connector 1 can be installed on the top cover of the scroll compressor. The exhaust pipe connector 3 can extend vertically, in which case the refrigeration oil droplets separated from the gas will flow back into the scroll compressor under gravity.

[0042] In addition, such as Figure 1 As shown, according to a second aspect of the present invention, a scroll compressor is provided, the scroll compressor including the exhaust pipe assembly for a scroll compressor as described above.

[0043] During operation, the gas in the scroll compressor passes through the helical blades 2 upon discharge. Due to the high density of the refrigerant oil droplets mixed in the gas, these droplets separate from the gas under centrifugal force after being guided by the helical blades 2, effectively reducing the oil discharge rate of the scroll compressor. The filter 4 in the exhaust pipe assembly of the scroll compressor filters out residual refrigerant oil in the gas, further reducing the oil discharge rate of the scroll compressor.

[0044] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The scope of protection of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the scope of the technology disclosed in this application. Such modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
