Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of compressors, in particular to an exhaust baffle for a compressor and the compressor. BACKGROUND

[0002] During the operation of the compressor, the refrigerant oil is dissolved in the refrigerant, and thus circulates in the air conditioning system along with the refrigerant. The oil discharge rate refers to the ratio between the mass or volume of the refrigerant oil discharged along with the compressed refrigerant and the mass or volume of the exhaust gas of the compressor during the operation of the compressor, which is usually expressed in percentage or decimal form.

[0003] A suitable oil discharge rate is one of the important factors to ensure the stable operation of the compressor system. If the oil discharge rate is too high, the supply of refrigerant oil in the compressor will be insufficient, which will cause poor lubrication, increase the friction and wear between components, and ultimately shorten the service life of the compressor.

[0004] At present, in the existing design of the compressor, the separation effect of the refrigerant oil and the refrigerant is not ideal, so that the refrigerant oil is directly discharged from the exhaust pipe along with the refrigerant, thereby causing the oil discharge rate of the compressor to be too high. CONTENT

[0005] Therefore, the purpose of the present application is to provide an exhaust baffle for a compressor and the compressor to solve the problem of high oil discharge rate of the compressor in the existing design of the compressor.

[0006] According to the first aspect of the present application, an exhaust baffle for a compressor is provided, wherein the exhaust baffle for the compressor comprises: a baffle body installed on the inner wall of the shell of the compressor, the baffle body being arranged outside the inlet of the exhaust pipe of the compressor; and a through hole being formed in the side of the baffle body opposite to the rotation direction of the compressor.

[0007] Preferably, the baffle body comprises: a cover body portion arranged outside the inlet of the exhaust pipe; and a side plate portion arranged on the outer periphery of the cover body portion, the side plate portion being connected with the inner wall of the shell.

[0008] Preferably, the side of the side plate portion close to the shell is formed as an arc surface, and the side plate portion is arranged closely to the inner wall of the shell.

[0009] Preferably, the cover body portion comprises: a flat plate portion arranged vertically inside the shell, a space being arranged between the flat plate portion and the inner wall of the shell; and a plurality of inclined plate portions connected to the plurality of sides of the flat plate portion, the side plate portion being connected to the inclined plate portion.

[0010] Preferably, the lower side of the cover portion is formed as an open side, the side plate portion is provided on the side of the outer periphery of the cover portion other than the lower side, and the inclined plate portion is connected to the side of the flat plate portion other than the lower side.

[0011] Preferably, the passage is formed on the upper side of the baffle body, and a space is formed between the passage and the open side.

[0012] Preferably, a projection of the baffle body on a vertical plane parallel to the flat plate portion is a rectangle with a notch formed at a corner, and the notch is a projection of the passage on the vertical plane.

[0013] Preferably, the notch is formed on the flat plate portion, the inclined plate portion, and the side plate portion, the notch interrupts the connection between the inclined plate portions, and the part of the side plate portion not interrupted by the notch is formed as a continuous structure.

[0014] Preferably, the notch is rectangular.

[0015] According to the second aspect of the present application, a compressor is provided, wherein the compressor comprises the exhaust baffle for a compressor as described above.

[0016] The exhaust baffle for a compressor and the compressor of the present application have the baffle body installed on the inner wall of the casing of the compressor. The baffle body is arranged outside the inlet of the exhaust pipe of the compressor to block the refrigerant gas containing the refrigeration oil. The passage is formed on the side of the baffle body opposite to the rotation direction of the compressor. Since the refrigerant gas flows along the rotation direction of the compressor, the passage is arranged on the side of the baffle body opposite to the flow direction of the refrigerant gas, so that the refrigerant gas cannot directly flow to the exhaust pipe, the flow path and time of the refrigerant gas are increased, the separation of the refrigeration oil from the refrigerant is facilitated, and the oil discharge rate is reduced. Thus, the problem of high oil discharge rate of the compressor in the prior art design can be effectively solved.

[0035] As Figures 1 to 6 shown, a discharge baffle for a compressor according to a first aspect of the present application includes a baffle body 1 and a through port 2.

[0036] In the following description, reference is made to the Figures 1 to 6 The specific structure of the above components of the discharge baffle for a compressor and the connection relationship of the above components are specifically described.

[0037] As Figures 1 to 6 shown, in an embodiment, the baffle body 1 can be installed on the inner wall of the tube shell 4 of the compressor. The baffle body 1 can be covered outside the inlet of the discharge pipe 5 of the compressor to block the refrigerant gas with the refrigeration oil. The through port 2 can be opened on the side of the baffle body 1 opposite to the rotation direction 6 of the compressor. Since the refrigerant gas flows along the rotation direction 6 of the compressor, the through port 2 is arranged on the side of the baffle body 1 cover opposite to the flow direction of the refrigerant gas, so that the refrigerant gas cannot directly flow to the inlet of the discharge pipe 5, thereby increasing the flow path and flow time of the refrigerant gas, which is beneficial to the separation of the refrigeration oil from the refrigerant, thereby reducing the oil discharge rate.

[0038] Preferably, as Figure 1 and Figure 2As shown in the embodiment, the refrigerant gas with refrigeration oil flows into the interior of the compressor from the gas inlet pipe of the compressor, and becomes high-temperature and high-pressure refrigerant under the compression of the scroll disc. The high-temperature and high-pressure refrigerant flows along the rotating direction 6 of the compressor under the influence of the rotation of the compressor (i.e. the rotation of the compressor middle part) after entering the middle and lower cavities of the compressor through the gas passage, and finally flows out at the inlet of the gas outlet pipe 5. In this process, the refrigerant cannot directly reach the inlet of the gas outlet pipe 5 because the baffle body 1 is arranged outside the inlet of the gas outlet pipe 5 of the compressor. The through port 2 is arranged on the side of the baffle body 1 which is opposite to the rotating direction 6 of the compressor. Specifically, the rotating direction 6 of the compressor can be the clockwise direction (as viewed from top to bottom). At this time, the direction in which the end of the baffle body 1 provided with the through port 2 points to the opposite end is the counterclockwise direction (as viewed from top to bottom). In this way, the through port 2 is arranged opposite to the flowing direction of the refrigerant gas, so that the refrigerant gas with refrigeration oil is forced to bypass, and the separation of refrigeration oil from the refrigerant gas is promoted.

[0039] Preferably, as Figures 1 to 6 As shown in the embodiment, the baffle body 1 can include a cover part 10 and a side plate part 11. The cover part 10 is arranged outside the inlet of the gas outlet pipe 5 to block the refrigerant gas from directly entering the inlet of the gas outlet pipe 5. The side plate part 11 can be arranged on the outer periphery of the cover part 10, and can be integrally formed with the cover part 10. The side plate part 11 can be bolted to the inner wall of the shell 4 to fix the cover part 10 to the shell 4 of the compressor.

[0040] Further, preferably, as Figures 1 to 5 As shown in the embodiment, the side of the side plate part 11 close to the shell 4 can be formed as an arc surface, and the curvature of the arc surface can be equal to the curvature of the inner wall of the shell 4. In this way, when the side plate part 11 is installed on the shell 4, the plate surface of the side plate part 11 can tightly adhere to the inner wall of the shell 4 to prevent the refrigerant gas from flowing into the cover part 10 through the gap between the side plate part 11 and the shell 4.

[0041] Still preferably, as Figures 2 to 6As shown in the embodiment, the cover body 10 can include a flat plate portion 101 and a plurality of inclined plate portions 102. The flat plate portion 101 can be a plate member approximately in the shape of a rectangle. The flat plate portion 101 can be vertically arranged inside the tube shell 4, and a space can be provided between the flat plate portion 101 and the inner wall of the tube shell 4 for the circulation of refrigerant gas. The plurality of inclined plate portions 102 can be respectively connected to the plurality of sides of the flat plate portion 101. The inclined plate portion 102 can be a plate member approximately in the shape of a trapezoid, one end of the inclined plate portion 102 can be connected to the flat plate portion 101, and the other end of the inclined plate portion 102 can be connected to the side plate portion 11. Some of the plurality of inclined plate portions 102 can be connected to each other (some of the inclined plate portions 102 can not be connected to other inclined plate portions 102) to prevent refrigerant gas from flowing into the cover body 10 through the gap between two inclined plate portions 102.

[0042] Preferably, as Figures 1 to 6 As shown in the embodiment, in the embodiment, the lower side of the cover body 10 can be formed as the open side 3, i.e., an opening is formed between the lower side of the cover body 10 and the inner wall of the tube shell 4. In this case, the side plate portion 11 surrounds the sides of the cover body 10 except the lower side, and the inclined plate portion 102 is connected to the sides of the flat plate portion 101 except the lower side, so that the lower side of the cover body 10 is formed as the open side 3. In this way, when the refrigerant gas flows along the outer wall of the cover body 10, the refrigerant gas can enter the inside of the cover body 10 through the opening of the lower side of the cover body 10, so as to improve the discharge efficiency of the refrigerant gas.

[0043] Further, preferably, in the embodiment, the through port 2 can be formed in the upper side of the baffle body 1, so that a space is formed between the through port 2 and the open side 3. In this way, the through port 2 and the open side 3 are not connected as a whole, so as to improve the structural strength of the whole of the discharge baffle for the compressor.

[0044] Preferably, as Figure 3 As shown in the embodiment, in the embodiment, when a vertical plane parallel to the flat plate portion 101 is taken as a projection plane, the projection of the baffle body 1 on the projection plane can be a rectangle with a notch 20 formed at a corner, and the notch 20 can be the projection of the through port 2 on the projection plane. Preferably, the shape of the notch 20 can be a rectangle. In this way, the whole structure of the discharge baffle for the compressor can be more regular, so as to be easy to process and install.

[0045] Preferably, as Figures 3 to 6As shown in the embodiment, the notches 20 can be formed on the flat plate portion 101, the inclined plate portion 102 and the edge plate portion 11, i.e. the portions of the notches 20 on the flat plate portion 101, the inclined plate portion 102 and the edge plate portion 11 are connected to form the through port 2. The notches 20 separate the connection between the portions of the inclined plate portion 102, and the portions of the inclined plate portion 102 which are not separated are connected as a whole. The portions of the edge plate portion 11 which are not separated by the notches 20 can be formed as a continuous structure to ensure the structural strength of the whole.

[0046] In addition, as Figure 1 and Figure 2 As shown in the embodiment, the notches 20 can be formed on the flat plate portion 101, the inclined plate portion 102 and the edge plate portion 11, i.e. the portions of the notches 20 on the flat plate portion 101, the inclined plate portion 102 and the edge plate portion 11 are connected to form the through port 2. The notches 20 separate the connection between the portions of the inclined plate portion 102, and the portions of the inclined plate portion 102 which are not separated are connected as a whole. The portions of the edge plate portion 11 which are not separated by the notches 20 can be formed as a continuous structure to ensure the structural strength of the whole.

[0047] In use, the exhaust baffle for compressor can block the flow of refrigerant gas, avoid the refrigerant gas with refrigeration oil directly flowing to the inlet of the exhaust pipe 5, so that the refrigerant gas needs to be additionally bypassed. In this way, the flow path and flow time of the refrigerant gas are increased, which is beneficial to the separation of the refrigeration oil from the refrigerant, and reduces the oil discharge rate of the compressor.

[0048] Finally, it should be noted that: the above-described embodiments are merely specific embodiments of the present application, used to illustrate the technical solutions of the present application, and are not limiting, the protection scope of the present application is not limited thereto, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand: any person skilled in the art within the technical scope disclosed by the present application, they can still modify or easily think of changes to the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features; and these modifications, changes or replacements do not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and all should be covered in the protection scope of the present application.
